重型肝炎低血糖的临床分析及防护对策

目的：探讨重型肝炎患者发生低血糖的临床意义,为针对性的防护提供依据。方法：检测20例健康献血员、44例急性肝炎、51例慢性肝炎及30例重型肝炎患者的空腹血糖水平进行比较,患者在发生低血糖症状时检测其血糖水平。结果：重型肝炎组的空腹血糖水平明显低于正常对照组、急性肝炎组及慢性肝炎组,在病程中低血糖发生率明显高于急性肝炎及慢性肝炎患者组,重型肝炎死亡组在病程中低血糖发生率明显高于存活组。结论：重型肝炎患者常发生低血糖,早期识别低血糖征兆,合理饮食,做好健康宣教是预防的关键;检测空腹血糖对判断重型肝炎危重程度和评估预后有重要意义。     

Secondary diseases in HIV-infected patients

During the period of 1980-1996 the dispensary observation of 50 HIV-infected patients was carried out. The clinical forms of the infection were distributed among these patients as follows: asymptomatic forms in 18 patients, persisting generalized lymphadenopathy in 8 patients, pre-AIDS in 14 patients, AIDS in 10 patients. Secondary infections were registered at the pre-AIDS stage. Dermatoses, oropharyngeal candidiasis occurred most frequently: in 52% of the HIV-infected patients. Herpes virus infection was registered in 46% of the patients. At the stage of AIDS during the generalized herpes virus and cytomegalovirus infections were registered in 5 and 7 patients respectively. Generalized forms of combined infections (herpes virus + fungi) prevailed, which caused the death of 7 patients at the terminal stage of AIDS.     

基于听觉刺激的意识障碍患者脑功能连通性研究

目的 目前对意识障碍（DOC）患者的分级评估仍是相关领域的重点和难点。因效性网络可以通过时间序列间的因果关系直观地反映信息传递方向,帮助人们更好地理解患者大脑不同区域之间的信息交互作用。本文结合脑电图和因效性网络探讨听觉刺激下无反应觉醒综合征（VS）患者与最低意识状态（MCS）患者的脑功能连通性差异。方法 共纳入23例DOC患者,采集并分析唤名刺激下的脑电信号,通过多元格兰杰因果方法构建脑功能网络,利用脑网络节点度、聚类系数、全局效率以及因果流向性等参量从脑区之间协同工作的角度对比研究听觉刺激下不同意识水平患者的网络特征。结果 唤名刺激下MCS患者的脑功能连通性强于VS患者,且呈现出因果流向差异,MCS与VS患者四个脑区的信息传递方向均不相同。结论 唤名听觉刺激下MCS患者的信息传递能力强于VS患者;与VS患者相比MCS患者为因果源的电极通道数增多,对其他脑区的信息输出增多。本研究可为DOC患者意识水平的分级评估提供一定的理论依据。     

Functional evaluation of the adenohypophysis with metoclopramide in hyperprolactinemic-amenorrheic women in relation to radiological findings on the sella turcica

The responses of the adenohypophyseal hormones to metoclopramide (MCP) were evaluated in hyperprolactinemic women with various radiological findings on the sella turcica. Serum PRL concentrations significantly increased after MCP administration in normal women, hyperprolactinemic patients with normal sella and patients with microadenoma, but not in macroadenoma patients with and without suprasellar expansion (SSE). The PRL response to MCP administration was significantly lower in hyperprolactinemic patients than in normal women. Serum TSH concentrations significantly increased after MCP administration in each group of subjects. The TSH response to MCP was significantly higher in patients with normal sella and patients with microadenoma than in normal women. However, the responses of PRL and TSH to MCP were not significantly different between patients with normal sella and patients with microadenoma. Therefore, they were not considered useful in distinguishing tumorous from nontumorous hyperprolactinemia. Serum LH concentrations significantly increased after MCP administration in patients with normal sella, patients with microadenoma and macroadenoma patients without SSE, but not in normal women or macroadenoma patients with SSE. The LH response to MCP was significantly higher in patients with microadenoma than in patients with normal sella. Serum FSH concentrations significantly increased after MCP administration only in patients with microadenoma. The different responses of the adenohypophyseal hormones to MCP in hyperprolactinemic women with various radiological findings on the sella turcica may be explained by the difference in the hypothalamic dopamine activity and in the impairment of the hypothalamic-pituitary system due to pituitary tumor.     

早期伤口切开对血循毒蛇咬伤患者预后的影响

目的探讨血循毒类毒蛇咬伤患者早期伤口切开对预后的影响。方法回顾性分析我院2011年3月~2014年3月诊治的血循毒类毒蛇咬伤患者223例的临床资料,总结并比较其临床特点及预后。结果本组患者轻度肿胀97例中,伤后12h内切开21例,未溃疡12例,Ⅰ°溃疡7例,Ⅱ°溃疡2例;晚期切开或未切开76例,未溃疡15例,Ⅰ°溃疡41例,Ⅱ°溃疡16例,Ⅲ°溃疡4例。中度肿胀患者85例中,伤后12h内切开32例,未溃疡8例,Ⅰ°溃疡21例,Ⅱ°溃疡2例,Ⅲ°溃疡1例;晚期切开或未切开53例,未溃疡6例,Ⅰ°溃疡16例,Ⅱ°溃疡24例,Ⅲ°溃疡7例。重度肿胀患者41例中,伤后12h内切开17例,Ⅰ°溃疡11例,Ⅱ°溃疡4例,Ⅲ°溃疡2例;晚期切开或未切开24例,Ⅰ°溃疡2例,Ⅱ°溃疡6例,Ⅲ°溃疡16例。在蛇伤后12h内切开的患者坏死溃疡的形成、肿胀程度的改善均明显优于晚期切开或未切开的患者,差异有显著统计学意义(P0.05)。结论随着患者凝血功能的改善,早期伤口切开对血循毒类毒蛇伤患者局部伤口状况有较好的改善作用。     

Five-and-a-half years' experience with percutaneous retrogasserian glycerol rhizotomy in treatment of trigeminal neuralgia

The results of treating trigeminal neuralgia with percutaneous retroganglionic glycerol rhizotomy in 319 patients from an overall series of 394 patients with 459 operations carried out over a period of 5 1/2 years are reported. Idiopathic trigeminal neuralgia was the diagnosis in 252 patients. 34 patients had trigeminal neuralgia associated with multiple sclerosis. The remaining 33 patients suffered from symptomatic trigeminal neuralgia or atypical facial pain. 230 patients (91.3%) with idiopathic trigeminal neuralgia and 30 patients (88.2%) with multiple sclerosis reported complete freedom from pain. In 12 patients (4.8%) of those with tic douloureux and in 1 patient (2.9%) with multiple sclerosis, pain was alleviated, and the patients required a reduced pharmacotherapy. 10 patients (3.9%) and 3 patients (8.8%) were considered to be treatment failures. The rate of recurrences within the first 2 years was 10.9 and 40.0%, respectively. In the long-term, the rate of recurrences in patients with tic douloureux was 36.9%. 144 patients (45.1%) noticed a hypesthesia. 132 patients (41.4%) had hypalgesia following the procedure, and there was a decrease of symptoms in the long-term observation in 20.0% of the patients. 59 patients (18.5%) developed dysesthesia postoperatively which regressed only to an inappreciable extent in the long-term course. In 16 patients (5.0%) exclusively with a preexisting organic lesion or who had received surgical pretreatment, there was a loss of corneal sensation. The investigation showed on the one hand the effectiveness of the method, but on the other hand also the possibility of marked sensory disorder in selected cases.     

Testicular responsiveness to long-term administration of hCG and hMG in patients with hypogonadotrophic hypogonadism

Steroidogenic responsiveness and amelioration of sperm number and motility following long-term intramuscular hCG and hMG administration were evaluated in 18 males with hypogonadotrophic hypogonadism (HH). The patients consisted of 13 patients with isolated gonadotrophin deficiency (IGD) and 5 patients hypophysectomized at an early or middle pubertal period. Basal serum levels of testosterone and 17 beta-estradiol were within prepubertal range in all patients before the treatment. Serum testosterone levels reached the normal adult male levels within 12-24 months of the treatment in only 2 of 7 younger patients and 1 of 6 older patients with IGD, whereas in all hypophysectomized patients serum levels of both testosterone and 17 beta-estradiol increased to the levels found in normal adult males within 6 months of the treatment. The mean peak levels of serum testosterone and 17 beta-estradiol, respectively, during the treatment were 2.1 +/- 0.8 (SD) ng/ml and 10.8 +/- 4.9 (SD) pg/ml in younger patients with IGD, 1.4 +/- 0.9 ng/ml and 9.7 +/- 5.1 pg/ml in older patients with IGD and 6.0 +/- 1.2 ng/ml and 34.2 +/- 14.8 pg/ml in hypophysectomized patients. Quantitative improvement in both sperm density and sperm motility were found in 4 of 7 younger patients, 1 of 6 older patients with IGD and all hypophysectomized patients, but only 3 of hypophysectomized patients (3 of 18 patients) could become fertile.     

Iron Absorption and Blood Loss in Patients with Hiatus Hernia

Iron absorption was measured in 28 patients, 19 of whom were anaemic. The mean absorption in the anaemic patients was 39% and in the non-anaemic patients 8%. Gastrointestinal blood loss was then measured in 26 of these patients. The mean estimated blood loss in the anaemic patients was 15 ml. a day and in the non-anaemic patients 3 ml. a day. In 16 of the 19 anaemic patients symptoms of anaemia were either the sole or the major complaint.     

幽门螺杆菌感染与慢性口臭关系的初步研究

目的 调查主诉口臭患者的幽门螺杆菌（H．pylori）感染率和主诉消化不良的口臭发生率。方法 研究对象为125例主诉慢性口臭患者和212例主诉慢性消化不良患者。口臭以口气挥发性硫化物（VSC）检测与闻诊联合诊断,H．pylori感染以^14C-尿素呼气试验诊断。结果 125例主诉慢性口臭的患者有87例是真性口臭,其余38例为假性口臭,真性口臭患者的H．pylori感染率显著高于假性口臭（40．2％和13．2％,P〈0．01）。212例主诉慢性消化不良的患者发生口臭105例（49．5％）、感染H．pylori 94例（44．3％）,H．pylori阳性患者的口臭发生率显著高于H．pylori阴性患者（57．5％和43．2％,P〈0．05）。无论何种主诉,大部分口臭患者属于VSC阳性（88．5％）,但H．pylori阳性患者和H．pylor阴性患者口气VSC水平差异无显著性,VSC阳性口臭和VSC阴性口臭的H．pylori感染率差异也无显著性。结论 H．pylori感染可能与口臭的发生有一定关系,但口气VSC并非由H．pylori直接产生。     

Atrial fibrillation precipitated by acute hypovolaemia.

Six patients with varying degrees of acute cardiorespiratory failure were seen. All patients deteriorated noticeably when rapid atrial fibrillation developed. In all patients intravenous digitalis failed to slow the ventricular response, and in three patients misguided attempts at electrical cardioversion failed. Haemodynamic monitoring showed a normal or low pulmonary artery occlusion pressure in all patients. Controlled expansion of plasma volume was associated with an immediate slowing of the heart rate in all patients, and the heart rate in all patients returned to sinus rhythm within 30 minutes of transfusion. It is suggested that hypovolaemia in critically ill patients may contribute to the development of atrial fibrillation.     

REGIONAL ISOLATION PERFUSION IN THE TREATMENT OF ADVANCED MALIGNANT DISEASE

Regional isolation perfusion with an alkylating agent was carried out in a small community hospital, using readily available equipment, ten times in nine cases of advanced malignant disease. Visible regression of tumor, either grossly or histologically, occurred in seven patients and decided subjective improvement occurred in five patients.The long range effect of the procedure could not be determined in the present series, not enough time having elapsed.Side effects included jaundice in four patients, massive necrosis of the tumor in one patient, nausea and vomiting in three patients, postoperative edema in five patients, wound infection in two patients, Horner''s syndrome in one patient, temporary alopecia in three patients, and depression of hemoglobin level in seven patients, of the leukocyte count in four patients and of the platelet count in four patients.A feature of the procedure used in the present series was a system of monitoring the escape of alkylating agent into the systemic circulation.     

131I]metaiodobenzylguanidine therapy in 20 patients with malignant pheochromocytoma.

Twenty patients, 16 male and 4 female (aged 11-76 years), with metastatic pheochromocytoma were treated in our Institution between 1985 and 1990. Metastases occurred in all patients: at presentation in 11 patients, with a 10 to 30 month delay in 7 patients, and 9 and 28 years later respectively in 2 patients. Catecholamines hyperproduction was present in all patients. Metaiodobenzylguanidine (MIBG) uptake was found in 16 patients after a diagnostic dose and only after a therapeutic dose in 1 patient. Surgery was performed on primary tumor (18 patients) and on distant metastases (10 patients). 131I-MIBG therapy was performed in 11 patients, 9 of whom were evaluable. The cumulative activity ranged from 3.7 to 26.3 GBq (100 to 711 mCi) in 1 to 6 courses. We observed symptomatic improvement (5 patients) and partial tumor response in 2 patients, which lasted for 28 and 9 months respectively, terminating with a rapidly progressing disease involving the bone marrow. Stabilisation was observed in 3 patients. Moderate myelosuppression occurred in 4 patients. Fifteen patients died with a median survival of 16 months (range 3-60). Response to therapy was poor and further evaluation of the presently available therapeutic approaches is needed.     

INDICATIONS FOR AND RESULTS FOLLOWING EXPLORATION OF THE COMMON BILE DUCT FOR STONES

Among 100 consecutive patients who had removal or drainage of the gallbladder and exploration of the common bile duct for stones, there were no serious, immediate or late complications and there were no operative deaths. Ninety-six of the 100 patients had stones in the gallbladder, in the common duct, or in both, and 52 of these patients had one or more stones in the common duct.Ten patients died subsequently of unrelated causes. Six patients were lost to followup. Of the 84 patients whose present condition is known, 75 or 89 per cent have had a completely satisfactory result. Six more patients have minor residual symptoms, and for them the result has been classified as good. In three patients, the results were unsatisfactory. Cholangiograms taken before the removal of the T-tube showed residual stones in two patients. In each instance, the stone or stones have been subsequently passed and both patients are in excellent condition.     

Sex difference in the paradoxical response of serum GH to thyrotrophin releasing hormone in cancer patients

It was demonstrated that thyrotropin-releasing hormone (TRH) elicited a paradoxical increase in basal GH levels in cancer patients. Out of 94 cancer patients, 50 were found to be GH responders and this phenomenon was more frequently recognized in female than in male cancer patients. In cancer patients under 59 years of age, the GH response to TRH was significantly greater in females than in males, although there was no sex difference in the GH response in patients above 60 years of age. In female cancer patients, the GH response to TRH was significantly greater in patients under 59 years of age than in patients above 60 years of age, while there was no age difference in the GH response in male cancer patients. It was concluded that paradoxical responses of serum GH to TRH were recognized in 53 per cent of cancer patients and were more frequently observed in female than in male cancer patients.     

Role of anti-cyclic citrullinated peptide antibodies in discriminating patients with rheumatoid arthritis from patients with chronic hepatitis C infection-associated polyarticular involvement

This study was performed to assess the utility of anti-cyclic citrullinated peptide (anti-CCP) antibodies in distinguishing between patients with rheumatoid arthritis (RA) and patients with polyarticular involvement associated with chronic hepatitis C virus (HCV) infection. Serum anti-CCP antibodies and rheumatoid factor (RF) were evaluated in 30 patients with RA, 8 patients with chronic HCV infection and associated articular involvement and 31 patients with chronic HCV infection without any joint involvement. In addition, we retrospectively analysed sera collected at the time of first visit in 10 patients originally presenting with symmetric polyarthritis and HCV and subsequently developing well-established RA. Anti-CCP antibodies and RF were detected by commercial second-generation anti-CCP2 enzyme-linked immunosorbent assay and immunonephelometry respectively. Anti-CCP antibodies were detected in 23 of 30 (76.6%) patients with RA but not in patients with chronic HCV infection irrespective of the presence of articular involvement. Conversely, RF was detected in 27 of 30 (90%) patients with RA, 3 of 8 (37.5%) patients with HCV-related arthropathy and 3 of 31 (9.7%) patients with HCV infection without joint involvement. Finally, anti-CCP antibodies were retrospectively detected in 6 of 10 (60%) patients with RA and HCV. This indicates that anti-CCP antibodies can be useful in discriminating patients with RA from patients with HCV-associated arthropathy.     

住院糖尿病患者中甲状腺结节的流行病学研究

目的:观察住院糖尿病患者中甲状腺结节的患病率,探讨二者间潜在的关系。方法:于2008年8月~2011年12月间对上海交通大学附属第一人民医院南院因糖尿病收治入院的全部患者进行甲状腺相关病史收集、血清甲状腺激素检测及超声波检查,以筛查甲状腺结节。结果:在收治的660例糖尿病患者中,住院期间发现并诊断合并有甲状腺结节患者为221例,患病率为33.5%。进一步分析糖尿病患者临床特征与甲状腺结节关系,男性为29.8%,女性为38.4%,明显高于男性患者,二者相比差异有统计学意义(P<0.05);糖尿病患者甲状腺结节患病率有随年龄增长而升高的趋势,与≤30岁年龄组相比,年龄51岁~70岁组及≥70岁组结节患病率均明显升高,差异有统计学意义(41.1%,37.6%15.4%,均P<0.05);1型糖尿病患者甲状腺结节患病率为24.1%,2型糖尿病中为35.3%,高于1型糖尿病,差异有统计学意义(P<0.05);糖尿病患者中,不同体重指数、病程、治疗方法组中甲状腺结节患病率相互比较均无明显差异性(均P>0.05)。结论:住院糖尿病患者中甲状腺结节患病率较高,尤其是女性、较大年龄及2型糖尿病患者更为突出,临床上有必要对这些患者进行甲状腺结节的筛查。     

The monoclonal antibody-defined CAR-3 antigen is a serological marker associated with pancreatic carcinoma

The monoclonal antibody-defined CAR-3 antigen is a new carcinoma associated marker which is expressed on a mucin-like molecule. Serum concentrations of CAR-3 were assayed in 181 patients with carcinomas of different organs, 20 patients with non-carcinomatous malignancies, 123 patients with inflammatory diseases and 150 healthy controls. Serum levels of CAR-3 were significantly increased in 51% of the patients with pancreatic carcinomas, in 60% of patients with biliary tract carcinomas and in about 15% of the patients with carcinomas of the digestive apparatus. Sera from patients with breast carcinomas were negative, as well as sera from patients with melanomas or sarcomas. CAR-3 values in samples from patients with chronic pancreatitis were constantly negative, as were samples from healthy donors. Significant concentrations of CAR-3 were detected in 20% of the sera from patients with acute pancreatitis and in 15% of the sera from patients with cirrhosis. Because of its high specificity for pancreatic carcinomas compared to chronic pancreatitis, CAR-3 seems a promising marker for distinguishing between neoplastic and chronic inflammatory diseases of the pancreas, whose differential diagnosis is difficult.     

Estrogen and progesterone receptors in gynecomastia

The etiology of gynecomastia is unknown. There seems to be no increased incidence of malignancies in patients with idiopathic gynecomastia; however, patients with Klinefelter syndrome exhibit an increased incidence of malignancy. The authors reviewed the results of 34 patients with gynecomastia diagnosed in adolescence who, following initial evaluation, had a mastectomy. The estrogen and progesterone receptors were analyzed in these patients. Three of the patients were diagnosed with Klinefelter syndrome. These three patients exhibited elevated amounts of estrogen and progesterone receptors. None of the patients who were not diagnosed with this syndrome demonstrated significant elevation of their estrogen or progesterone receptors. The presence of elevated estrogen and progesterone receptors in patients with Klinefelter syndrome provides a potential mechanism by which these patients may develop breast neoplasms. The absence of elevated estrogen and progesterone receptors in patients with idiopathic gynecomastia may serve to clarify why these patients' disease rarely degenerates into malignancy.     

Indications for and results following exploration of the common bile duct for stones

Among 100 consecutive patients who had removal or drainage of the gallbladder and exploration of the common bile duct for stones, there were no serious, immediate or late complications and there were no operative deaths. Ninety-six of the 100 patients had stones in the gallbladder, in the common duct, or in both, and 52 of these patients had one or more stones in the common duct. Ten patients died subsequently of unrelated causes. Six patients were lost to followup. Of the 84 patients whose present condition is known, 75 or 89 per cent have had a completely satisfactory result. Six more patients have minor residual symptoms, and for them the result has been classified as good. In three patients, the results were unsatisfactory. Cholangiograms taken before the removal of the T-tube showed residual stones in two patients. In each instance, the stone or stones have been subsequently passed and both patients are in excellent condition.     

Extracellular circulating nucleic acids in human plasma in health and disease

The concentration of extracellular DNA and RNA in blood plasma of healthy donors, trauma patients, patients with breast and lung cancer, nonmalignant breast tumors and nonmalignant lung diseases were estimated. Significant amounts of extracellular RNA were found in plasma of trauma patients. The concentration of DNA and RNA in plasma of trauma patients correlates with the extent of posttraumatic organ failure. Extracellular RNA was not found in the plasma of breast cancer patients and patients with nonmalignant breast tumors, whereas a very high concentration of extracellular RNA was found in patients with malignant and nonmalignant diseases of lung.
