HPV感染对阴道微生态炎症反应的影响

目的探究HPV感染与阴道微生态、炎症反应的关系。方法选取2017年11月至2018年11月在我院治疗的70例HPV感染患者(研究组),随机选取同一时期来我院进行体检的健康者70例(对照组)。治疗前后分别对研究组和对照组研究对象进行HPV检测、阴道分泌物检查以及炎症反应检查,观察并记录两组研究对象的情况。结果治疗前研究组患者HPV感染情况[高危型HPV感染31例(44.3%),低危型HPV感染为39例(55.7%)]明显高于对照组[高危型HPV感染2例(2.8%),低危型HPV感染5例(7.1%)](t=38.314 0、33.345 0,均P0.05);研究组患者阴道微生态(乳杆菌为3 000±50、厌氧菌为1 050±100、需氧菌为800±65)明显低于对照组(乳杆菌为5 114±222、厌氧菌为2 334±100、需氧菌为1 500±100)(t=15.395 1、14.521 1、16.126 0,均P0.05);研究组阴道炎症发病情况[阴道毛滴虫阴道炎29例(41.43%)、念珠菌阴道炎为22例(31.43%)、细菌性阴道炎19例(27.14%)]明显多于对照组[阴道毛滴虫阴道炎11例(15.71%)、念珠菌阴道炎9例(12.86%)、细菌性阴道炎8例(11.43%)](χ~2=11.340 0、7.002 0、5.552 0,均P0.05)。结论临床上HPV感染很常见,患者多伴发阴道炎症,HPV感染患者阴道正常菌群变少,阴道微生态环境紊乱。

Association of serum amyloid A levels with adipocyte size and serum levels of adipokines: Differences between men and women

The aim of this study was to characterize the association between adipocyte enlargement and circulating levels of serum amyloid A (SAA). Furthermore, we wanted to search for possible associations with measures of glycemic control and levels of circulating adipokines and/or inflammatory markers in men and women with a large range in body mass index. The study cohort consisted of 167 subjects, 114 non-diabetic and 53 with Type 2 diabetes. Adipocyte diameter as well as circulating levels of SAA, C-reactive protein (CRP), adiponectin, leptin, interleukin-6, tumor necrosis factor alpha, glucose and insulin were measured. Women had higher serum levels of SAA than men (p = 0.044). SAA levels were weakly but positively correlated with BMI (p = 0.043) and % body fat (p = 0.027) in all subjects as well as subcutaneous adipocyte diameter (p = 0.034) in women. Furthermore, in all subjects we found correlations between SAA levels and levels of CRP (p < 0.001), interleukin-6 (p < 0.001), leptin (p = 0.003), insulin (p = 0.006), HbA1c (p = 0.02) and HOMA-IR (p = 0.002). A majority of the correlations were strongest in women. In conclusion, serum levels of SAA are strongly correlated with serum levels of inflammatory markers as well as measures of glycemic control. There seems to be large sex differences in these associations suggesting that sex-specific factors need to be considered when analyzing SAA levels in relation to metabolic disease.     

Distinct distribution of HPV types among cancer-free Afro-Caribbean women from Tobago

Human papillomavirus (HPV), a sexually transmitted virus causes cervical carcinomas, and is associated with ∼36% of oropharyngeal tumours where HPV16 is the predominant genotype. The cervical cancer incidence rate in Trinidad and Tobago is about two times higher than the worldwide rate. We have for the first time determined the prevalence and type distribution of cervical HPV infections among cancer-free Afro-Caribbean women from Tobago, and compared it with the HPV subtypes observed in their oral cavity. Thirty-five per cent of the women were cervical HPV positive. The most common high-risk type detected in the cervix was HPV45 rather than HPV16 and 18. The prevalence of HPV infection in the oral mucosa was 6.6%. The distribution of HPV genotypes in healthy Tobagonian women is different from that reported in studies conducted in European and North American populations. This may have important implications for vaccine introduction in this and other Afro-Caribbean countries.     

Peripheral mononuclear blood cells contribute to the obesity-associated inflammatory state independently of glycemic status: involvement of the novel proinflammatory adipokines chemerin,chitinase-3-like protein 1, lipocalin-2 and osteopontin

Inflammation is a critical contributor to the pathogenesis of metabolic disorders with adipose tissue being crucial in the inflammatory response by releasing multiple adipokines with either pro- or anti-inflammatory activities with potential functions as metabolic regulators. Peripheral blood mononuclear cells (PBMC) have been proposed as representative of the inflammatory status in obesity. The aim of the present study was to evaluate the contribution of PBMC to the obesity-associated chronic inflammation analyzing the expression of novel adipokines. Samples obtained from 69 subjects were used in the study. Real-time PCR determinations were performed to quantify gene expression levels in PBMC of novel adipokines including chemerin, chitinase-3-like protein 1 (YKL-40), lipocalin-2 (LCN-2) and osteopontin (OPN), and their circulating concentrations were also determined by ELISA. We show, for the first time, that PBMC gene expression levels of chemerin (P < 0.0001), chitinase-3-like protein 1 (P = 0.010), lipocalin-2 (P < 0.0001) and osteopontin (P < 0.0001) were strongly upregulated in obesity independently of the glycemic state. Circulating concentrations of these adipokines followed the same trend being significantly higher (P < 0.05) in obese normoglycemic and type 2 diabetic patients compared to lean volunteers and also associated (P < 0.05) with their corresponding mRNA levels in PBMC. These results provide evidence that alterations in inflammation-related adipokines are manifest in PBMC, which might contribute to the low-grade chronic inflammation that characterizes obesity.

宫颈HPV16持续感染阶段宫颈P16和Ki67的表达及其与宫颈癌变的关系

目的:探讨宫颈人乳头状瘤病毒(HPV)16持续感染阶段宫颈P16和Ki67的表达及其与宫颈癌变的相关性。方法:采用P16/Ki67免疫组化双染法检测102例HPV16持续感染者、136例非持续感染者宫颈组织P16、Ki67蛋白的表达,并根据免疫组化结果分组为双染阳性组、双染阴性组。所有患者随访观察2年,比较两组患者的结局及宫颈癌前病变的发生率。结果:P16、Ki67及P16/Ki67双染的阳性率分别为40.3%、44.5%及34.0%,HPV16持续感染患者P16、Ki67及P16/Ki67双染的阳性率均显著高于非持续感染患者(P0.05)。HPV16持续感染患者的P16、Ki67蛋白表达呈显著正相关(P0.05)。HPV16持续感染患者中,双染阳性组的病情持续和进展比例明显高于双染阴性组,也明显高于HPV16非持续感染(双染阴性组、双染阳性组)患者(P0.05)。HPV16持续感染患者中,双染阳性组进展为HSIL及以上病变发生率为32.5%(13/40),显著高于双染阴性组6.5%(P0.05)。结论:P16,Ki67双染阳性在HPV16持续感染阶段与宫颈上皮内病变疾病进展成正相关,对HPV16持续感染进展为宫颈高度病变有预警价值,可作为HPV16阳性早期治疗的敏感指标。     

宫颈高危型HPV感染后的转归与阴道微生态的相关性分析

对宫颈高危型HPV HR-HPV感染后的转归进行阴道微生态及其危险因素分析, 以探讨宫颈高危型HPV感染后的转归与阴道微生态的相关性。

选取2019年7月至2020年9月在中山市博爱医院妇科门诊就诊的进行机会性宫颈癌筛查女性, 对其中符合研究纳入标准及排除标准的291例HR-HPV阳性者进行阴道微生态分析并随访, 在排除宫颈病变后, 6~12个月后再次进行HR-HPV检测, 若再次阳性者为持续感染组, 转阴性者为病毒清除组。分析2组的阴道微生态是否存在差异, 并进一步分析HR-HPV持续感染的危险因素。

符合研究纳入标准及排除标准的291例HR-HPV阳性者中持续感染组173例, 占59.45%, 平均年龄43.02岁±9.16岁(22~64岁); 病毒清除组118例, 占40.55%, 平均年龄40.26岁±9.00岁(24~66岁)。2组间年龄比较差异无统计学意义(F=0.041, P=0.839)。2组的阴道微生态分析表明, 病毒持续感染组的细菌性阴道病感染率、乳杆菌异常率、pH值异常率、白细胞酯酶阳性率分别为15.03%、41.62%、74.41%和22.54%, 这4项指标均大于病毒清除组, 2组间差异有统计学意义(χ²=7.088、14.369、9.585、4.487, P=0.008、＜0.001、0.002、0.034)。而2组在外阴阴道假丝酵母菌感染、滴虫性阴道炎、菌群密集度、多样性、过氧化氢酶、唾液酸苷酶、β-葡萄糖醛酸苷酶和乙酰氨基葡萄糖苷酶等指标方面的差异无统计学意义。Logistic回归分析显示乳杆菌异常、pH值异常是HR-HPV持续感染的危险因素, 其OR值分别为2.076(95%CI: 1.156~3.728)、2.121(95%CI: 1.218~3.688)(P＜0.05)。

宫颈HR-HPV感染后的转归与细菌性阴道病、白细胞酯酶阳性、乳杆菌异常及pH值异常存在一定的相关性, 尤其是乳杆菌异常、pH值异常是HR-HPV持续感染的危险因素, 需要重视。同时, 临床工作中可以考虑通过积极治疗下生殖道感染性疾病, 重建阴道微生态平衡, 以利于HR-HPV的清除, 降低宫颈病变的发生率。

     

细菌性阴道病与HPV感染、宫颈癌前上皮内瘤变及宫颈浸润癌相关性的研究进展

细菌性阴道病(bacterial vaginosis,BV)可以通过破坏机体的免疫调节作用使HPV在宫颈组织中持续感染,导致宫颈癌前上皮内瘤变(cervical intraepithelial neoplasia,CIN)和宫颈癌。同时对BV的诊断可以作为预测CIN发展和宫颈癌发生的生物预测方法,对BV的诊断除了传统的Amsel标准和Nugent评分外,还可通过16S rRNA高通量测序、探针检测和实时PCR等新的分子生物学方法来精确诊断。应用益生菌治疗菌群失调的同时可以预防CIN的发展和宫颈癌的发生,因此通过改善菌群失调来调节机体对HPV病毒的免疫反应可能成为治疗CIN和宫颈癌的新方法。     

Human Papillomavirus (HPV) 16 E6 seropositivity is elevated in subjects with oral HPV16 infection

IntroductionHuman Papillomavirus (HPV) 16 E6 serum antibodies are common in people with HPV-related oropharyngeal cancers (HPV-OPC), but not the general population. We explored HPV16 seroprevalence in people with and without oral HPV16 infection, the cause of HPV-OPC.MethodsOral rinse samples were collected semiannually and tested for 36 types of HPV DNA by PCR. HPV16 E6 serum antibodies were tested at the visit of first oral HPV detection in participants with prevalent (n = 54), or incident (n = 39) oral HPV16 DNA; or at baseline in matched participants with no oral HPV16 DNA (n = 155) using multiplex serology assay. Predictors of seropositivity were examined using logistic regression.ResultsHPV16 E6 seropositivity (7.5% vs 0.7%; p = 0.005) but not seropositivity to the other HPV16 antigens, was significantly more common in those with than without oral HPV16 infection. There were only 8 HPV16 E6 seropositive participants, but oral HPV16 DNA remained a strong predictor of E6 seropositivity after adjustment for other risk factors (aOR = 14.6 95%CI, 1.7–122.5). Seroprevalence was similar in those with prevalent (7.4%; 4/54), and incident (7.7%; 3/39) oral HPV16 infection (p = 1.00). E6 seroprevalence was associated with reduced oral HPV16 clearance, but was not statistically significant (HR = 0.65 95% CI, 0.16–2.70).Seropositive participants were primarily male (87.5%), HIV-positive (75.0%; median CD4 cell-count of 840) and had oral HPV16 DNA (87.5%). History of an HPV-related cancer (0/8) or HPV-related anogenital dysplasia (1/8) was rare, and 4 participants had recent screening showing no anogenital dysplasia.DiscussionHPV16 E6 seropositivity was higher among people with than without oral HPV16 infection, despite no known anogenital disease in these participants.     

Increased plasma levels of adipokines in preeclampsia: relationship to placenta and adipose tissue gene expression

Adipokines are predominantly secretory protein hormones from adipose tissue but may also originate in placenta and other organs. Cross-sectionally, we monitored maternal plasma concentration of adiponectin, resistin, and leptin and their mRNA expression in abdominal subcutaneous adipose tissue and placenta from preeclamptic (PE; n = 15) and healthy pregnant (HP; n = 23) women undergoing caesarean section. The study groups were similar in age and BMI, whereas HOMA-IR tended to be higher in the PE group. In fasting plasma samples, the PE group had higher concentrations of adiponectin (18.3 +/- 2.2 vs. 12.2 +/- 1.1 microg/ml, P = 0.011), resistin (5.68 +/- 0.41 vs. 4.65 +/- 0.32 ng/ml, P = 0.028), and leptin (34.4 +/- 3.2 vs. 22.7 +/- 2.1 ng/ml, P = 0.003) compared with the HP group. Adiponectin and leptin concentrations were still different between PE and HP after controlling for BMI and HOMA-IR, whereas resistin concentrations differed only after controlling for BMI but not HOMA-IR. We found similar mean mRNA levels of adiponectin, resistin, and leptin in abdominal subcutaneous adipose tissue in PE and HP women. When data were pooled from PE and HP women, resistin mRNA levels in adipose tissue also correlated with HOMA-IR (r = 0.470, P = 0.012) after controlling for BMI and pregnancy duration. Resistin mRNA levels in placenta were not significantly different between PE and HP, whereas leptin mRNA levels were higher in PE placenta compared with HP. Thus increased plasma concentrations of adiponectin and resistin in preeclampsia may not relate to altered expression levels in adipose tissue and placenta, whereas both plasma and placenta mRNA levels of leptin are increased in preeclampsia.     

保妇康栓联合LEEP锥切术治疗宫颈上皮内瘤变伴高危型HPV感染的疗效观察

目的 探讨保妇康栓联合LEEP锥切术治疗宫颈上皮内瘤变（CIN）伴高危型HPV感染的临床疗效。方法 选取2015年1月至2016年1月收治的CIN合并HPV感染患者120例,按照随机数字法分为观察组和对照组,每组60例,对照组给予LEEP术进行治疗,观察组在对照组基础上于术后给予保妇康栓进行治疗,观察并比较两组患者阴道出血量及出血时间、阴道排液量及时间、宫颈创面愈合时间,并对术后3个月、6个月CIN治疗效果及HPV清除效果进行评价。结果 观察组患者阴道出血量及出血时间、阴道排液量及时间、宫颈创面愈合时间均显著小于对照组（t=13.29、6.61、11.46、6.01、4.78,P<0.05）,且盆腔疼痛发生率显著低于对照组（χ2=11.64,P<0.05）。观察组患者术后3个月、术后6个月宫颈细胞学检查CIN治愈率为86.7%、96.7%,分别高于对照组的71.7%、81.7%（χ2=4.09、6.99,P<0.05）。观察组患者术后3个月、6个月HPV转阴分别为36例、47例,转阴率分别为60.0%、78.3%,对照组术后3个月、6个月HPV转阴分别21例、28例,转阴率分别为35.0%、46.7%。观察组患者术后3个月、6个月的HPV转阴率均显著高于对照组（χ2=5.64、12.84,P<0.05）。且观察组患者术后3个月、6个月单一基因型及混合基因型HPV转阴率也均显著高于对照组（χ2≥3.96,P<0.05）。结论 保妇康栓联合LEEP术可显著改善CIN伴高危型HPV感染患者术后临床症状,提高CIN治愈率和HPV转阴率。     

The association of depressive symptoms with inflammatory factors and adipokines in middle-aged and older Chinese

Background

Studies in Western populations find that depression is associated with inflammation and obesity. The present study aimed to evaluate the relation of depressive symptoms with inflammatory factors and adipose-derived adipokines in middle-aged and older Chinese.

Methodology/Principal Findings

Data were from 3289 community residents aged 50–70 from Beijing and Shanghai who participated in the Nutrition and Health of Aging Population in China project. Depressive symptoms were defined as a Center for Epidemiological Studies of Depression Scale (CES-D) score of 16 or higher. Plasma concentrations of C-reactive protein (CRP), interleukin-6 (IL-6), adiponectin, resistin, plasminogen activator inhibitor-1 (PAI-1) and retinol binding protein 4 (RBP4) were measured. Of the 3289 participants, 312 (9.5%) suffered from current depressive symptoms. IL-6 level was higher in participants with depressive symptoms compared to their counterparts in the crude analyses (1.17 vs. 1.05 pg/mL, p = 0.023) and this association lost statistical significance after multiple adjustments (1.13 vs. 1.10 pg/mL, p = 0.520). Depressive symptoms were not associated with increased mean levels of any other inflammatory factors or adipokines in the unadjusted or adjusted analyses.

Conclusions/Significance

We found no evidence that depressive symptoms were associated with inflammatory factors and adipokines in the middle-aged and older Chinese populations. Prospective studies and studies in clinically diagnosed patients are needed to confirm our results and clarify the relation of depression with inflammatory factors and adipokines.

Cervico-vaginal dysplasia--papillomavirus-induced and HIV-1 infection: role of correlated markers for prognostic evaluation

Sexually-transmitted diseases (STD) can facilitate the progression of HIV-1 infection. Among them, as we have previously demonstrated, cervico-vaginal dysplasia-papillomavirus (HPV)-induced, together with HSV-2 co-infection, seems to be correlated with a more evident immunodepression in HIV-positive women, compared with other sexually transmitted diseases. Here we have analysed some of the main correlated markers of HIV-1 infection progression: CD4 + T lymphocyte concentration, CD4 +/CD8 + T cells ratio, HIV-1 RNA loads and haemoglobin (Hb) concentration in 30 HIV-1 positive women co-infected with HPV, and suffering from cervico-vaginal dysplasia, in different stages. In particular, we noticed a positive correlation, evaluated by Spearman's test, between the degree of progression of dysplastic stages (CIN1 --> 3) until invasive carcinoma (IC) and HIV-1 RNA loads (C(s) = +0.78; p < 0.001), and in contrast, a negative correlation between the same stages of progression and respectively CD4 + T cell concentration (C(s) = -0.54; p = 0.01), ratio (C(s) = - 0.63; p = 0.002) and Hb concentration (C(s) = -0.85; p < 0.001). In conclusion, it is important to underline that low levels of Hb generally paralleled the degree of immunodepression. In fact CD4 + T cell levels and ratio positively correlated with Hb concentrations respectively, with C(s) = + 0.83; p < 0.001 and C(s) = + 0.90; p < 0.001. Finally, the most efficacious antiretroviral combined therapy (HAART = Highly Active Antiretroviral Therapy) can improve the above described laboratory parameters in HIV-1/HPV co-infected women and seems to prevent the progression of CIN1 to the following stages of the dysplastic disease.

目的 观察宫颈电环切除术(LEEP术)联合保妇康栓治疗宫颈上皮内瘤变(CIN)合并高危型人乳头瘤病毒(HPV)持续感染的疗效.方法 158例病例随机分为两组,对照组79例,治疗组79例.治疗组患者在LEEP术后于阴道内放置保妇康栓,对照组未放置任何药物.观察两组患者宫颈创面愈合时间、术后并发症的发生情况、CIN消退及高危型HPV持续感染的情况.结果 两组患者官颈创面愈合时间、并发症发生情况比较差异无统计学意义(P＞0.05);而CIN消退差异有统计学意义(P＜0.05);高危型HPV持续感染率差异有统计学意义(P＜0.01).结论 LEEP术联合保妇康栓治疗CIN合并高危型HPV持续感染疗效满意,是较为理想的方法.     

病毒持续性感染难治愈的因素及对策

病毒持续性感染引起的病程多为慢性或反复发作,难以治愈,在部分患者甚至可引发肿瘤或自身免疫性疾病等,是严重危害人类健康及造成社会重大经济负担的常见病及多发病。持续性感染难以治愈的原因涉及病毒基因组与宿主细胞染色体整合,或以附加体的形式长期存在,以及病毒的酶或蛋白抑制机体的免疫应答等特性。此外,机体天然免疫或获得性免疫低下、免疫网络失调及感染微环境改变等,也是病毒建立并维持持续性感染的原因。本文根据持续性感染难以治愈的原因,从病原学与机体免疫应答两方面研讨一些对策,希望以此为切入点,为治疗持续性感染提供新思路与新策略。
