Objective To study the roles of soluble intercellular adhesion molecule 1(sICAM 1) in the pathogenesis of pregnancy induced hypertension (PIH). Methods Serum levels of sICAM 1 were measured by enzyme linked immunosorbent assay(ELISA) in 65 women with PIH (PIH group : 15 mild PIH, 24 moderate PIH and 26 severe PIH) and 25 normal pregnant women (control group). The serum levels of IL 1? and TNF ? were measured by chemiluminescent ELISA at the same time. Results Serum concentrations of sICAM 1 were significantly higher ( P

Objective To identify risk factors for anastomotic leakage,and study the influence of high ligation of the inferior mesenteric artery on anastomotic leakage after rectal cancer resection.Methods The chi-test and the student t test were used for statistics.Clinical data were analyzed for 291 patients who underwent rectal cancer resection between August 2008 and November 2011.Results Anastomotic leakage occurred in 27 (9.3％) patients.Anastomotic leakage significantly increased in patients with tumours located within 10 cm from the anal verge,in male patients,and intraoperative blood loss.The use of high ligation of inferior mesenteric artery,which was associated with lower tumor location and surgical modality,was not a risk factor for anastomotic leakage,though it was associated with tumor stage and postoperative urinary retention.Conclusions Anastomotic leakage after rectal cancer resection is related to the tumor level,male gender,and perioperative bleeding,use of a high tie was not associated with an increased rate of symptomatic anastomotic leakage.

The synchronized HeLa cells were used to study the effect of protein kinase A(PKA) inhibitor on the progression of S phase. Synchronized cell s in S phase were obtained by the method of TdR double block through 3H-T dR incorporation assay. The PKA inhibitor typeⅢ obviously increased the level of 3H-TdR incorporation of S phase in HeLa cells. In contrast with contro l, the activity of thymidine kinase (TK) in S phase increased, too. It indicated that PKA played an inhibitory role in S phase progression of HeLa cells. With t he method of Western blotting, the PKA inhibitor typeⅢ enhanced the level of C yclinA and PCNA, inhibited the expression of p21, which is a negative regulator of cell cycle, but had no effect on the expression of CDK2. The results showed t hat PKA could negatively regulate the S phase progression by affecting the level of CyclinA, PCNA and influencing the expression of p21 protein. This may be one of the molecular mechanisms which is involved in the negative regulation of S p hase progression by PKA in HeLa cells.

Objective • To explore the correlation of anxiety and depression with sleep quality and quality of life in elderly patients with percutaneous coronary intervention (PCI). Methods • A total of 297 elderly patients undergoing PCI were surveyed according to hospital anxiety and depression scale (HADS), Piusburgh sleep quality index (PSQI) and 12-item short form health survey version 2.0 (SF-12v2) on the day before they were discharged from two hospitals (Xinhua Hospital, Shanghai Jiao Tong University School of Medicine and Shanghai Sixth People's Hospital, Shanghai Jiao Tong University). All data was based on their subjective feelings in the past month. Spearman correlation analysis was performed on the scores of anxiety and depression to sleep quality and life quality. The multiple linear regression was used to analyze the influencing factors of life quality. Results • 21.5% of the patients were assessed as anxiety positive, and 22.2% were assessed as depression positive, both higher than those of the patients in general hospitals of China (both P=0.000). The average score of patients' sleep quality was 6.50±3.46, which was higher than the domestic norm (P=0.000). The average score of patients' quality of life was 132.20±30.83, the physiological score was 60.44±17.58, and the psychological score was 71.76±15.96. Correlation analysis showed that there was a significant positive correlation between total scores of anxiety and depression and total scores of sleep quality (P=0.026, P=0.027), and a significant negative correlation between total scores of anxiety and depression and total quality of life scores, the physiological scores and the psychological scores (all P=0.000). The linear regression equation of anxiety and depression scores and quality of life scores in elderly patients with PCI was significant (P=0.000, R2=0.246). Conclusion • The incidence of anxiety and depression in elderly PCI patients was high in the last month before admission, and the sleep was poor. The more obvious the anxiety or depression, the worse the quality of sleep and quality of life. Attention should be paid to the relations of anxiety and depression to sleep quality and quality of life, and efforts should be made to improve the negative emotions of patients and enhance their sleep quality and quality of life.

Objective To examine the different effects of impulsive and aggressive personality on college students' suicide attempt. Methods Four thousand nine hundred eighteen sophomores and juniors were selected according to the principle of cluster sampling from Beijing agricultural university and Beijing university of information science and tech?nology. Four thousand seven hundred ninety-seven of them completed the survey. Their impulsive and aggressive person?ality were evaluated by the Barratt Impulsiveness Scale-Chinese Versions (BIS-CV) and the Buss-Perry Aggression Questionnaire-Chinese Versions (AQ-CV). A self-made questionnaire were used to investigate suicidal idea and self-in?jury/suicidal behavior of college students. Results Among the sophomores and juniors, 18 participants had self-injury/suicidal behavior (3.75‰) and 1843 had suicidal idea (38.42%). Compared with the students who didn’t have self-inju?ry/suicidal behavior, those who once had self-injury/suicidal behavior had significantly higher BIS-CV score (P<0.01) and higher scores of non-planning and motor factors (P<0.05). They also had significantly higher score in AQ-CV and the factors of physical aggression, verbal aggression, anger, hostility and pointing to the self attacks (P<0.01). Conclu? sions The college students with self-injury/suicidal behavior have higher tendency in impulsive and aggressive personali?ty. Therefore, it is necessary to prevent suicide behavior, form high impulsive and aggressive intention and behavior.

Objective To investigate the mechanism and significance of low concentration nitric oxide (NO) inhalation in the treatment of pulmonary thromboembelism in swine. Method The pulmonary thromboem-bolism(PTE) model was made in 15 healthy infantile swines which were subsequently assigned to either control group (n = 8) or NO group (n = 7). Swines of the control group were not treated with any medicine, while 10 ppm of NO was administered by continuous inhalation for 2 hours to swines of NO group. Volume of physiological dead space (VDphy), volume of alveolar dead space (VDalv), intrapulmonary shunt (Qs/Qt), mean pulmonary arterial pressure (PAP), systolic blood pressure (SBP), heart rate (HR), cardiac output (CO), arterial blood pH (pH), arterial partial pressure of carbon dioxide (PaCO2) and arterial partial pressure of oxygen (PaO2) were measured 30 min before and 0 min, 30 min, 60 min, 120 min and 180 min after establishment of VIE. Results The post-FIE VDphy, VDalv, Qs/Qt and PAP in both groups increased markedly after PTE compared with the cor-responding pre-PTE measurements (P < 0.01). Post-FIE PaO2 of both groups decreased significandy (P <0.05 and P <0.01), while significance difference was found between pre- and post-PTE HR, SBP, CO, pH or PaCO2 in neither groups (P > 0.05). Both post-PTE PAP and VDalv in NO group were markedly lower(P <0.05 and P <0.01) and beth PaCO2 and PaO2 were much higher than those of the control group (P <0.05). No signi-fieant difference were found in other measurements between two groups. Conclusions Pulmonary arterial pressure may be lowered, alveoli dead space may be reduced and PaCO2 increased by low concentration NO inhalation for the treatment of PIE without decline in haemodynamic status.

Objective To investigate the mechanism and significance of low density nitric oxide (NO) in-halation combined with urokinase (UK) in treatment of pulmonary thromboembolism in swine. Method PIE model was estabhshed in 12 healthy infant swines, which were subsequently assigned to UK group or UK+NO ter establishment of the PIE model;in the UK+NO group, swines received continuous NO inhalation of 10 ppm NO for two hours in addition to administration of UK no done in the UK+NO group. Volume of physiological dead space (VDphy), volume of alveolar dead space (VDalv), intrapoulmonary shunt (Qs/Qt), mean ptdmonary arteri-al pressure (PAP), systolic blood pressure (SBP), heart rote (HR), cardiac output (CO), arterial blood pH val-ue, arterial partial pressure of carbon dioxide (PaCO2) and arterial partial pressure of oxygen (PaO2) were mea-sured at 30 min before and 0 min, 30 min, 60 rain, 120 min and 180min after establishment of pulmonary em-bolism.All date were analyzed by ANOVA (SNK-q test),and P<0.05 was considered as significantly differet. Results After PE, VDphy, VDalv, Qs/Qt and PAP of both groups increased markedly compared with the pre-PE values (P<0.01), but the post-PE PAP showed a tendency of decline as time passed. Post-PE PaO2 of both groups decreased significantly (P<0.05 and P<0.01). There were no significant differences in HR, SBP, CO, pH or PaCO2 between pre-PE and post-PE (P>0.05). Both pre- and Post-PE PAP of UK+NO group were markedly less than those of the UK group (P<0.05 and P<0.01). No significant difference was found in other measurements between the two groups. Conclusions UK combined with low density NO inhalation may lower pul-monary arterial pressure promptly to alleviate PIE without distur bance in hemodynamics or gas exchange status and without pulmonary raterial pressure rebound.

Objective To observe the changes of plasma neuropeptide Y(NPY) and neurotensin(NT) levels in patients with essential hypertension and the relationship between those changes and damage of cardiac function. Methods Eighty patients of essential hypertension and 28 normal controls were chosen. The cardiac function was divided into 3 classes on the standard of New York Heart Association(NYHA). The plasma NPY,NT concentration was determined by radioimmunoassay. Results The level of NPY in hypertension patients was higher than that of the normal controls(P

Objective To compare the number of lymph node dissected by intraoperative lymphatic mapping guided D2 gastrectomy and that by standard D2 gastrectomy plus lymphadenectomy in patients of advanced gastric cancer. Methods In this study 20 advanced gastric cancer cases received intraoperative peritumor injection of carbon nanoparticles suspension ( group 1 ) and D2 lymphadenectomy was guided by the black-stained lymph nodes. 21 cases undergoing standard D2 lymphadenectomy served as controls (group 2). The number of lymph nodes removed and the condition of lymphatic metastasis in two groups, blackstained lymph nodes in group 1, and postoperative complications were compared. Results The average lymph nodes dissected in group 1 (35. 1 ± 13.4) were higher than in control group (26.2 ±7.8). The differences were statistically significant (t =2. 126, P =0. 034). The number of removed N2 and N3 lymph nodes in group 1 were more than that in control group. The total black-stained ration of lymph nodes was 52. 7% in group 1. The positive rate of lymph nodes was higher in black-stained lymph nodes (27.6%) than in unstained lymph nodes ( 10. 8% ) in group 1 and in control group ( 16. 9% ). The differences were also statistically significant ( x2 = 6. 034, P = 0. 016; x2 = 5. 142, P = 0. 023 ). Postoperative afferent loop obstruction developed in one case in group 1. Conclusions Lymphatic mapping guided D2 radical gastrectomy plus lymphadenectomy increases the number of lymph nodes dessected and improves the efficiency of positive lymph nodes excision for patients of advanced gastric cancer.

Objective To study the relationship between the prevalence of hyperuricemia and thyroid dysfunction. Methods 10 405 active and retired workers aged 21 to 89 years in a Petrochemical Corporation in Ningho area of Zhejiang Province were included. Serum thyroid-stimulation hormone (TSH), free thyroxine thyroid diseases, the prevalence of thyroid dysfunction was 4.2%, 2.9% in male and 7.2% in female. The percentage of subjects with low TSH concentration was 0.4% in male and 0.9% in female,the percentage of TSH subjects,the serum uric acid was significantly increased in subjects with high TSH (P<0.05) and not an independent factor associated with hyperuricemia (OR=1.61 for male and 1.72 for female, P value was less than 0.01 for both). Conclusion The prevalence of hyperuricemia is significantly associated with increased TSH concentration. Overt or subclinical hypothyroidism may be risk factors for hyperuricemia.
