Association between human papillomavirus infection and adverse pregnancy outcome / 预防医学

Objective To investigate the infection rate of human papillomavirus(HPV)among pregnant women, and to explore the effect of HPV infection on adverse pregnancy outcome. Methods A total of 1 679 pregnant women in hospital were collected for the research. The flow-through hybridization and genechip(HybriMax)method was used to detect the infection of HPV. Univariate analysis was used to analyze the factors affecting HPV infection in pregnant women. The binary logistic analysis was used to analyze risk factors affecting adverse pregnancy outcome. Results HPV infection rate was 31.39%(527/1 679), including 14.23%(239/1 679)of HR-HPV, 15.54%(261/1 679)of LR-HPV and 1.61%(27/1 679)of mixed of HR-HPV and LR-HPV. Univariate analysis showed that there was significant difference in initial sex age, education level and smoking history between infection group and non-infection group, with statistical difference(P<0.05). The incidence rate of adverse pregnancy outcomes in infection group(31.50%) was significant higher than that of non-infection group(9.81%), with statistical difference(P<0.01). The incidence rate of premature rupture of fetal membranes, newborn respiratory papillomatosis and other adverse pregnancy outcomes among HR-HPV group, LR-HPV group and mixed group had no significant difference (P>0.05). Binary logistic regression analysis showed HR-HPV infection(OR=4.194, 95% CI: 3.099-5.675), LR-HPV infection(OR=1.771, 95%CI: 1.288-2.434)and mixed type infection(OR= 3.350, 95%CI: 1.630-7.735)were the risk factors affecting adverse pregnancy outcome(P<0.01), however, age and times of gestation had no statistical significance in the binary logistic analysis(P>0.05). Conclusion HPV infection was the risk factors for adverse pregnancy outcome, which indicated that screening work in pre-pregnancy and pregnancy, and persisting in early prevention, early detection and early treatment could reduce the incidence rate of adverse pregnancy outcome.

Study on effect elements of anthers opening-closing movement and its cell morphology regulatory mechanism of Paris polyphylla var. yunnanensis / 中国中药杂志

In order to study the effect elements of anthers opening-closing movement of Paris polyphylla var. yunnanensis, and its cell morphology regulatory mechanism. Anthers daily opening in the morning and closing in the evening and its corresponding ecological elements changes were recorded. Different light, temperature, humidity experiment and artificial rainfall experiment were designed to observe the effect on anthers opening-closing movement, paraffin sections were made to observe the cell morphology change when the anthers daily opening and closing. The result showed that the movement of anthers daily opening and closing was regulated by ecological elements. The overall trend was high temperature and strong light, low humidity was favorable for anther opening, and low temperature, weak light, high humidity was favorable for anther closing. In this experiment, the effect of these ecological elements on the movement of anthers opening from strong to weak was humidity, temperature, light. The effect of these ecological elements on the movement of anthers closing from strong to weak was light, humidity, temperature. The direct contact of the raindrops causes the rapid closing of the anthers in the rain. Observing the cell morphology change when anthers opening and closing, it was a pollen sac dehydration and water-absorption process, different light, temperature and humidity conditions induce different physiological activities in the cell, which caused the cell osmotic pressure change, eventually resulting in anther opening and closing movement. But anthers closing caused by the rain was a simple physical adjustment process, the raindrops fell on the anthers directly, which caused anthers soaked water and change of the cell osmotic pressure, then resulting in anther closing.

Elemene's effect on apoptosis of human lung cancer cells of A549 and its related molecular mechanisms / 上海预防医学

Objective To study the inhibitory effect and molecular mechanism of elemene on A549 lung cancer cells. Methods Lung adenocarcinoma cancer cells A549 were treated with elemene of 10 mu g/mL, 20 mu g/mL, 40 mu g/mL, 80 mu g/mL, 160 mu g/mL, marked as observation group 1~5, with a blank control group 6 set up.The cell cycle and cell apoptosis rate were detected with flow cytometry at 24 h, 48 h, 72 h after elemene treatment, and eIF4E protein levels by Wsetern Bolt method. Results (1) At 24 h after treatment, there was no obvious change in each cell cycle, and the difference in cell percentage in G2/M phase, the sub-G1 phase was of no statistical significance ( P>0.05);and at 48 h, 72 h after treatment, the cell ratio in observation group during G2/M phase was significantly decreased compared with control group, and the difference between the two was statistically significant (P<0.05), but compared within the observation point, there was no statistical difference (P>0.05); The higher the concentration of elemene was, the more obvious was its inhibitory effect.( 2 ) With the growth of drug concentration, the cell apoptosis rate was markedly elevated .(3) In comparison with control group, 24 h after treatment, eIF4E expression in observation group was on the decline.And the higher the concentration was, the lower was the expression. Conclusion The inhibitory effect of elemene on A549 lung cancer cell is strong, and its influence on cell cycle is of dependency on dose and time; Cell apoptosis rate increased with the increase of drug concentration, but higher doses can cause side effects, reduce the apoptosisrate;physiological mechanism of A549 cell proliferation inhibition may be related to expression of inhibiting eIF4E.

Breeding system of Paris polyphylla var. yunnanensis / 中国中药杂志

<p><b>OBJECTIVE</b>To provide the basic guidance for seed breeding and cross-breeding of Paris polyphylla var. yunnanensis.</p><p><b>METHOD</b>The floral behavior and pollinators were observed; 0.5% TTC solution was used for the pollen viability test and benzidine and -H2O2 was used for estimation of the stigma receptivity. The mating systems were tested by out crossing index (OC1), and pollination experiment was carried out by bagged and emasculated test in the field.</p><p><b>RESULT</b>Commonly, stigma lobes spread slightly, and anthers started presenting the pollen from the outer ring while the flower was just beginning to open. Consequently, the distance between the stigma and its own pollen was relatively far, this "floral behavior" may be conducive to outcrossing. Then the flower entered the later period, while the stigma lobes spread widely, anthers all split, and this "floral behavior" shortened the stigma and its own pollen's distance, which may be conducive to selfing. P. polyphylla was partly protogynous. Stigma life-span was about 10-12 d. After anther dehiscence, the pollen viability maintained about 10% within 2 days, and 20% within 10 days. The value of out crossing index (OC1) was 4. By pollination experiment and pollinators observed, P. polyphylla was self-compatible, but no capacity for autonomous self-fertilization; In natural circumstances, outcrossing fructification rate was low, and mainly anemophilous. Assisted selfing-fertilization fructification rate was higher, spider was the main pollinators.</p><p><b>CONCLUSION</b>P. polyphylla has a mixed mating system with self-pollination and cross-pollination characteristics. Floral behavior has important adaptive significance in avoiding female and male interference, outcrossing, and delayed selfing. P. polyphylla is ambophily (a combination of both wind and insect pollination), pollinators changes due to environment. Pollen limitation is the main cause of low fructification rate under natural conditions.</p>

Relationship between aggressive behavior and interpersonal attribution in senior primary school students / 第二军医大学学报

Objective To obtain knowledge about aggressive behavior and interpersonal attribution of senior primary school students, and to explore the relationship between them. Methods Stratified random sampling was used to conduct a questionnaire survey in students of the fourth grade, fifth grade and sixth grade. The students were surveyed about their general situation and by aggressive behavior scale and interpersonal attribution scale. The relation between aggressive behavior and interpersonal attribution was analyzed using multiple linear regression. Results The score of aggressive behavior of male students was significantly higher than that of female students; the total, physical aggression, anger and hostility scores of male students of the fourth and fifth grades were significantly higher than those of sixth grade(P0. 05). Multiple linear regression analysis showed that scores of situation factor of external control and fortune were both positively correlated with scores of total aggressive behavior, physical aggression, indirect aggression, anger and hostility when gender and grade were adjusted(P<0. 05); the scores of effort factor of internal control and situation factor of external control had a positive correlation with score of verbal aggression(P<0. 05). Conclusion The aggressive behavior of senior primary school students is mainly correlated with the external control factors of interpersonal attribution. Students with higher score of external control factors have a higher score of aggressive behavior, suggesting that the intervening measures should be taken to change the interpersonal attribution style to prevent aggressive behavior among these students.

Treatment for prosthetic valve endocarditis after mitral valve replacement therapy / 中国综合临床

Objective To review the experience of treatment for prosthetic valve endocarditis(PVE)after mitral valve replacement(MVR)in 16 cases.Methods From September 1979 to December 2010,16 patients were diagnosed as PVE after MVR by modified Duke University diagnostic criteria.There were 10 males and 6 females.Their ages ranged from 19 to 55 years old(mean 28 years old).The incidence of PVE was 0.97％(16/1657)after MVR.Blood culture positive was in 5 cases.Medical treatment alone was performed in 10 patients who were treated by using Penicillin or Vancomycin with other broad-spectrum antibiotics,using Fluconazole and Amphotericin if necessary.Combined medical and surgical management were performed in 6 cases.One emergency case was operated because of obstinate heart failure.Five cases underwent operation after adequate antibiotics treatment and general condition improvement.The infective tissue and vegetation were aggressively debrided after the infective prosthetic valve removed.Before the new valve was replaced paravalvular tissue must be flushed with diluted iodine solution and large quantities of normal saline.Tricuspid valve repair (TVR)was performed during the same period in 3 cases.Results Hospital death occurred in 8 patients and only 2 patients were recovery in group with medical treatment only.The main reasons of death were infective shock and cardiac failure in 4 patients,cerebral complications(embolism or bleeding)and multiple organs failure in 4 cases.While 6 patients cured after combined medical and surgical management.Follow-up had been carried out in 8 cases for 1.7 to 15 years(mean 5.1 years).Eight years later one patient was re-operated because of severe tricuspid regurgitation and paravalvular leak.There was no PVE recurrence in others.Conclusion Combined medical and surgical management for PVE get a better result than medical treatment alone.Good prognosis lies in timely diagnosis,adequate antibiotics,aggressive debridement of infective tissue and better myocardium protection during operation.

Long-term effects of biodegradable versus durable polymer-coated sirolimus-eluting stents on coronary arterial wall morphology assessed by virtual histology intravascular ultrasound / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>The durable presence of polymer coating on drug-eluting stent (DES) surface may be one of the principal reasons for stent thrombosis. The long-term coronary arterial response to biodegradable polymer-coated sirolimus-eluting stent (BSES) in vivo remained unclear.</p><p><b>METHODS</b>Forty-one patients were enrolled in this study and virtual histology intravascular ultrasound (VH-IVUS) was performed to assess the native artery vascular responses to BSES compared with durable polymer-coated SES (DSES) during long-term follow-up (median: 8 months). The incidence of necrotic core abutting to the lumen was evaluated at follow-up.</p><p><b>RESULTS</b>With similar in-stent late luminal loss (0.15 mm (0.06-0.30 mm) vs. 0.19 mm (0.03-0.30 mm), P = 0.772), the overall incidence of necrotic core abutting to the lumen was significantly less in BSES group than in DSES group (44% vs. 63%, P < 0.05) (proximal 18%, stented site 14% and distal 12% in BSES group, proximal 19%, stented site 28% and distal 16% in DSES group). The DSES-treated segments had a significant higher incidence of necrotic core abutting to the lumen through the stent struts (73% vs. 36%, P < 0.01). In addition, more multiple necrotic core abutting to the lumen was observed in DSES group (overall: 63% vs. 36%, P < 0.05). Furthermore, when the stented segments with necrotic core abutting to the lumen had been taken into account only, DSES-treated lesions tended to contain more multiple necrotic core abutting to the lumen through the stent struts than BSES-treated lesions (74% vs. 33%), although there was no statistically significant difference between them (P = 0.06).</p><p><b>CONCLUSIONS</b>By VH-IVUS analysis at follow-up, a greater frequency of stable lesion morphometry was shown in lesions treated with BSESs compared with lesions treated with DSESs. The major reason was BSES produced less toxicity to the arterial wall and facilitated neointimal healing as a result of polymer coating on DES surface biodegraded as time went by.</p>

Effects of doxazosin and its enantiomers on serum lipid levels in rabbits fed by an atherogenic diet / 中国应用生理学杂志

<p><b>OBJECTIVE</b>To observe the effects of (-)doxazosin(DOX), (+)DOX and (+/-)DOX on serum lipid levels and the mortality rates of the rabbits fed by an atherogenic diet.</p><p><b>METHODS</b>Male white New Zealand rabbits were fed by an atherogenic diet for 4 weeks. 8 rabbits whose serum TC <10 mmol/L were confirmed as normal diet group and were fed normally. 40 rabbits whose serum TC >10 mmol/L were randomly divided into 4 groups (n=10): atherogenic diet group, atherogenic diet with (-)DOX group, atherogenic diet with (+)DOX group and atherogenic diet with (+/-)DOX group, which were intraperitoneally injected with (-)DOX, (+)DOX and (+/-)DOX for 9 weeks respectively. Normal and atherogenic diet group were intraperitoneally injected with double distilled water. After 9 weeks administration of (+/-)doxazosin and its enantiomers, effects of the three agents on serum levels of total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) were observed.</p><p><b>RESULTS</b>The mortality rate of the rabbits fed by an atherogenic diet for 13 weeks was 40%, and it was much higher than that of the rabbits fed by a normal diet (10%). The mortality rates in the rabbits treated with (-)DOX and (+/-)DOX were lower than that in the rabbits fed by a normal diet (10%). Serum LDL-C level of the rabbits was increased markedly after 4 weeks of atherogenic diet, and it was further increased significantly (P < 0.05 and P < 0.01) during the continued 9 weeks of atherogenic diet. However, serum LDL-C levels were not further increased significantly (P > 0.05) during the continued 9 weeks of atherogenic diet in the rabbits treated with (-)DOX, (+)DOX and (+/-)DOX, respectively.</p><p><b>CONCLUSION</b>(-)DOX and (+/-)DOX increase the survival rate and improve LDL-C disorder mildly in the rabbits fed by an atherogenic diet. The improvements in LDL-C induced by (-)DOX and (+/-)DOX, however, might not be the reason for exploration about the increased survival rate in the rabbits fed by an atherogenic diet.</p>

Coronary plaque characterization of nonculprit or nontarget lesions assessed by analysis of in vivo intracoronary ultrasound radio-frequency data / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Unheralded sudden death and acute myocardial infarction are common manifestations of coronary atherosclerosis. Such events are related to thrombotic occlusion at the site of non-flow limiting atherosclerotic plaques in epicardial coronary arteries. This study aimed to assess plaque characterization of nonculprit lesions in patients with acute coronary syndrome (ACS) compared with those with stable angina pectoris (SAP) determined by analysis of intravascular ultrasound (IVUS) radiofrequency (RF) data.</p><p><b>METHODS</b>In 81 patients, nonculprit vessels with < 50% diameter stenosis and nontarget segment of culprit vessels with < 50% diameter stenosis were studied with IVUS. Tissue maps were reconstructed from RF data using IVUS-Virtual Histology software.</p><p><b>RESULTS</b>Mean lipid core percentage was significantly higher in patients with ACS than in those with SAP ((25.78 +/- 6.30)% vs (9.11 +/- 4.90)%, P < 0.001). In addition, patients with SAP showed more fibrotic vessels ((59.66 +/- 16.87)% vs (49.07 +/- 10.20)%, P < 0.001). There was no significant difference in either mean calcium ((4.37 +/- 2.40)% vs (5.12 +/- 3.00)%, P = 0.225) or fibrolipid ((24.94 +/- 9.40)% vs (25.82 +/- 13.60)%, P = 0.731) percentages in nonculprit vessels, but the mean calcium percentage was significantly higher in nontarget lesions of culprit vessels ((5.51 +/- 3.29)% vs (3.57 +/- 2.10)%, P = 0.003). In addition, there was a positive correlation between lipid core and remodeling index (RI) (r = 0.847, P < 0.001) and a negative correlation between fibrous tissue and RI (r = -0.946, P < 0.001).</p><p><b>CONCLUSIONS</b>In this study, in both nonculprit vessels and nontarget lesion of culprit vessels, plaque characterization of nonculprit lesions determined by spectral analysis of IVUS RF data was significantly different in patients with ACS. The percentage of lipid core was significantly higher in patients with ACS than in those with SAP. Conversely, SAP patients showed more fibrotic content. In vivo plaque composition and morphological changes were related to remodeling of the coronary artery tree.</p>
