1.5 Mb deletion of chromosome 4p16.3 associated with postnatal growth delay,psychomotor impairment,epilepsy, impulsive behavior and asynchronous skeletal development

Several Wolf-Hirschhorn syndrome patients have been studied, mouse models for a few candidate genes have been constructed and two WHS critical regions have been postulated, but the molecular basis of the syndrome remains poorly understood.     

规范化护理在急性肾出血介入微创栓塞治疗中的价值探讨

目的:探讨规范化护理在急性肾出血介入微创栓塞治疗中的价值。方法:回顾性分析我科38例急性肾出血患者采用明胶海绵、微弹簧圈、聚乙烯醇(PVA)等栓塞剂栓塞出血动脉,规范性做好介入术前、术中、术后护理。结果:除2例肉眼血尿持续10天,其他36例病人全部在术后3天内尿液由介入前全血尿转为淡红色,并在7天肉眼血尿彻底消失。结论:规范化护理是确保介入微创栓塞治疗急性肾出血顺利完成及成功的重要环节,加强术前、术中、术后护理能明显减少介入微创栓塞治疗后再出血的发生,提高介入治疗效果。     

哈白猪产后子宫内微生物区系的研究

实验通过用子宫内膜活检采样器采集子宫内容物样品、活菌计数、细菌的分离鉴定和药敏实验等方法 ,对 8头体重 12 0～ 15 0kg、年龄在 6～ 8岁的母猪产后子宫复旧期间子宫内的细菌进行研究 ,以探讨产后子宫内细菌的变化规律及对子宫复旧的影响。实验结果表明 ,在产后 0～ 1d ,子宫内细菌数量呈直线增加 ,在产后第 7d时 ,子宫内的细菌数量达到最多 ,此后其细菌数量逐渐下降 ;到产后第 2 5d时 ,子宫内的细菌数量已降为 (7.35± 2 .5 4 )× 10 2 个 /mg子宫样品。而细菌的种类在产后 1～ 7d较少 ,7～ 13d呈增长趋势 ,产后第 13d以后 ,细菌种类开始减少 ,直至接近于零。这说明产后子宫内环境经历了从污染到净化的过程 ,直至子宫复旧完毕。

Resection of meningiomas with implantable microwave coagulation

Implantable microwave coagulation was used to perform resection on 62 patients that had intracranial meningiomas. When 20–60 W microwave power was applied for 15 s, the temperature at the center of the tumor tissue was 43–63°C; 30 mm from the center, the temperature was under 40°C. Histological changes in the center of the tumor showed coagulative necrosis, diminished nuclei, and obliterated blood vessels. The changes at 10–20 mm from the center of the tumor showed coagulative necrosis and degeneration and, 30–50 mm from the center of the tumor, showed normal cell morphology after microwave coagulation. The thermal field in brain tumor has an effective diameter of about 40 mm. No side effects on the normal brain tissues were observed. The amount of blood loss during the operation was minimal while the meningioma was coagulated, especially when the meningioma was located at the skull base or in the parasagittal or cerebral convexity region. After microwave coagulation, the entire tumor could easily be removed. Among the 62 surgically treated cases, gross total tumor excision was 85%. No postoperative complications occurred after microwave coagulation, and there was no operative mortality in the series. We believe that this new technique has the advantage of simplicity, less blood loss, and smooth postoperative procedures. Hemostatic effects during the operation are satisfactory, and blood transfusion can be reduced by 50–60%. © 1996 Wiley-Liss, Inc.

Effect of Bleeding on Lipid Oxidation in the Chub Mackerel Muscle

Chub mackerel samples were prepared by two different methods of killing, struggling death in iced sea water (control) and instant death by mechanical bleeding (bleeding). The malonaldehyde content in the muscles of the bleeding sample were significantly higher than those of the control after 119 h of storage at 0 °C.     

Negligible effects of blood sampling on reproductive performance and return rates of Tree Swallows

Blood sampling is a frequently used method of collecting genetic and physiological data in natural populations, and understanding the possible impact of blood sampling on individuals and populations is important, both for the welfare of study organisms and to avoid introducing bias into analyses using bled individuals. Most studies of birds have revealed minimal negative effects of blood sampling. However, Brown and Brown (2009. Auk 126: 853–861) found that blood sampling reduced return rates of Cliff Swallows (Petrochelidon pyrrhonota), suggesting that these results are not always generalizable and that swallows (Hirundinidae) may be particularly sensitive to blood sampling. We examined the possible effects of blood sampling on the reproductive performance of female Tree Swallows (Tachycineta bicolor) and the return rates of both females and offspring in a population in New York state. To reduce the chances of Type II error, we tested 15 possible effects of blood sampling on reproductive performance and return rates using generalized linear mixed models. Overall, our results suggest that blood sampling had few negative effects on within‐year reproductive success or survival of adult females. The one exception was that bleeding nestlings had a negative effect on the number of young that fledged in broods of five or six nestlings. Bleeding did not negatively impact return rates of females or nestlings in our Tree Swallow population. Our results support those of other studies suggesting that blood sampling has few negative effects on within‐year reproductive success or survival of adult females, and reiterate the importance of systematically testing for possible effects with datasets compiled over multiple years because such effects may be impossible to detect via direct monitoring during a single breeding season.     

MCM10: An effective treatment target and a prognostic biomarker in patients with uterine corpus endometrial carcinoma

Molecular profiling has been applied for uterine corpus endometrial carcinoma (UCEC) management for many years. The aim of this study was to explore the role of MCM10 in UCEC and construct its overall survival (OS) prediction models. Data from TCGA, GEO, cbioPotal and COSMIC databases and the methods, such as GO, KEGG, GSEA, ssGSEA and PPI, were employed to bioinformatically detect the effects of MCM10 on UCEC. RT-PCR, Western blot and immunohistochemistry were used to validate the effects of MCM10 on UCEC. Based on Cox regression analysis using the data from TCGA and our clinical data, two OS prediction models for UCEC were established. Finally, the effects of MCM10 on UCEC were detected in vitro. Our study revealed that MCM10 was variated and overexpressed in UCEC tissue and involved in DNA replication, cell cycle, DNA repair and immune microenvironment in UCEC. Moreover, silencing MCM10 significantly inhibited the proliferation of UCEC cells in vitro. Importantly, based on MCM10 expression and clinical features, the OS prediction models were constructed with good accuracy. MCM10 could be an effective treatment target and a prognostic biomarker for UCEC patients. The OS prediction models might help establish the strategies of follow-up and treatment for UCEC patients.     

坤泰胶囊联合米非司酮治疗围绝经期功能失调性子宫出血的疗效及对bFGF、VEGF水平的影响

摘要 目的：分析坤泰胶囊联合米非司酮治疗围绝经期功能失调性子宫出血（DUB）的疗效及对碱性成纤维细胞生长因子（bFGF）、血管内皮细胞生长因子（VEGF）水平的影响。方法：选取2021年10月-2022年10月在合肥市第一人民医院滨湖院区妇科门诊就医的88例围绝经期DUB患者作为研究对象,采用随机数据表法将其分为研究组和对照组,每组各44例,两组患者入组后均给予常规对症治疗,对照组患者在此基础上给予口服米非司酮胶囊,用量为每日1次,每次10 mg。研究组患者在对照组疗法的基础上给予口服坤泰胶囊,用量为每日3次,每次2 g。两组患者均连续服用3个月。对两组患者的疗效指标及治疗前和治疗3个月时的子宫内膜厚度、血清卵泡刺激素（FSH）、黄体生成素（LH）、泌乳素（PRL）、雌二醇（E₂）、bFGF、VEGF水平进行比较。对两组患者治疗期间的不良反应进行比较。结果：研究组患者的疗效等级分布优于对照组,有效率高于对照组（P<0.05）。两组患者治疗前的子宫内膜厚度及血清性激素、bFGF、VEGF水平的差异均无统计学意义（P>0.05）,在治疗3个月末,两组患者的子宫内膜厚度及血清FSH、LH、PRL、E₂水平均较治疗前降低,血清bFGF、VEGF水平均较治疗前升高（P<0.05）,研究组患者在治疗3个月末的子宫内膜厚度及血清FSH、LH、PRL、E₂水平均低于对照组,血清bFGF、VEGF水平均高于对照组（P<0.05）。两组不良反应均为轻度,在未经治疗的情况下患者可耐受,未见因不良反应而中断治疗的患者。两组各项不良反应发生率和不良反应总发生率的差异均无统计学意义（P>0.05）。结论：在围绝经期DUB的治疗中,采用坤泰胶囊联合米非司酮的中西医治疗方案,在临床疗效优于单用米非司酮方案,能够更加显著地改善血清激素水平、抑制子宫内膜增生、提升bFGF、VEGF等血管生成因子的表达水平。
