Subject To explore the features of the abnormalities of the sex chromatin and the sex chromosome of the patients with mental disorders. Methods The sex chromatin in the cells of buccal mucous membrane of the 2 784 patients with mental disorders were examined by using a blinding and random way. The chromosome karyotypes in peripheral blood were further examined in those whose measure showed abnormal. The comparison group consisted of 1 069 normal persons.Results Compaired with the control group,the average frequency of Y chromatin in the male patients [(28.0±6.6)%] and the average frequency of X chromatin in the female patients [(22.3±8.0)%] rose significantly ; the average frequency of X chromatin in the female patients of the schizophrenia subgroup and the affective disorder subgroup were higher than that of neurosis and psychogenic mental disorder subgroup. X chromatins of eight male patients were positive and the karyotypes of the abnormal X chromosome were 47,XXY in 3 cases and 47,XXY/46,XY in 5 cases, the rate of 47,XXY was 7.7 , it rose significantly to the control group. X chromatin of two female patients were negative and the karyotypes of the abnormal X chromosome was 45,X/46,XX, the rate of 45,X was 1.2 ; one female patient had double X chromatin and the karyotypes of the abnormal X chromosome was 47,XXX/46,XX,there is no abnormal sex chromatin and sex chromosome in the control group.Conclusions The higher rate of the sex chromatin might be closely associated with the tendency of heredity of mental disorders , and the rate of the lacking X chromosome in females and the increasing X chromosome in males rise in the patients with mental disorders.

Objective To assess the risk factors for pneumonia in patients with acute stroke. Methods Three hundred and forty patients with acute stroke were studied, and risk factors for pneumonia such as demographics, history of hypertension, diabetes and smoking, initial blood pressure, body temperature, fasting plasma glucose level, C-reactive protein, National Institutes of Health Stroke Scale ( NIHSS) scores, degree of dysphagia and mechanical ventilation were evaluated. Besides, the correlation between incidence of pneumonia and pneumonia scores in patients with acute stroke was studied. Results Pneumonia was developed in 63 patients (18.5%). Logistic regression analysis revealed that age, gender, initial NIHSS scores, dysphagia and mechanical ventilation were independent predictors for pneumonia (P <0.05). The incidence of pneumonia gradually increased with the pneumonia scores. Conclusion The occurrence of pneumonia after acute stroke is associated with older age, male gender, high NIHSS scores, dysphagia and mechanical ventilation. The pneumonia scores can be adopted to identify the risks of pneumonia after acute stroke.

Background and purpose:The study hasfound that tumornecrosis factor-related apoptosis inducing ligand (TRAIL) can enhance the cytotoxic effect of chemotherapeutic drugs on tumor cells. The aim of our study was to investigate the effects of the tumor TRAIL and cisplatin combined application on the growth and apoptosis of human ovarian cancer cell lines SKOV3 and OVCAR3, and the possible mechanism.Methods:Under the combined application of cisplatin and TRAIL, MTT method and flow cytometry were used to detect the proliferation and apoptosis of SKOV3 of OVCAR3 cells; the mRNA expression levels of death receptors, DR4 and DR5, were detected by real-time lfuorescent quantitative polymerase chain reaction (RTFQ-PCR). At the same time, the protein expression levels of DR4 and DR5 were detected by Western blot.Results:SKOV3 and OVCAR3 cells were sensitive to TRAIL protein, and with the increasing of TRAIL protein concentration, cell growth inhibitory rate up to 64%. When the
combination application of TRAIL and cisplatin, the inhibition rate of the two cells reached more than 92%, and the two drugs showed high synergistic effect, compared with the single drug group (P<0.05). Flowcytometry analysis indicated that the synergistic killing effect of TRAIL and cisplatin was mainly due to the cell apoptosis. RTFQ-PCR and Western blot detection results showed that the DR4 and DR5 were up-regulated under the combined application of TRAIL and cisplatin.Conclusion:In vitro, TRAIL and cisplatin combined application can signiifcantly inhibit the proliferation of human ovarian cancer cells and induce tumor cell apoptosis. TRAIL can obviously enhance the sensitivity of cisplatin to tumor cells. The mechanism may be related to the increased death receptor DR4 and DR5 expression level.

AIM:This study was to investigate the expression and significance of Bmi-1 in colorectal carcinoma (CRC),and to explore the effect of Bmi-1 on Ki67 expression in human CRC.METHODS:The samples from sixty CRC,thirty adenomas and twenty normal colorectal mucosal tissues were used in this study. The expression of Bmi-1 protein was detected by immunohistochemistry. The clinicopathological features and survival rate of patients were also analyzed.RESULTS:The overexpression of Bmi-1 was respectively 25.0%,6.7%and 0% in CRC and adenomas as well as normal colorectal mucosal tissues. The results showed that the expression of Bim-1 was significantly higher in CRC,compared with that in adenomas and normal colorectal mucosal tissues (P0.05). Kaplan-Meier survival analysis showed that the overexpression of Bmi-1 reduced significantly survival of CRC patients (P

Objective To compare the effect of midazolam and propofol on cytokine balance in patients undergoing cardiac valve replacement under CPB. Methods Twenty NYHA class Ⅱ - Ⅲ patients with rheumatic heart disease scheduled for elective cardiac valve replacement under CPB were randomly divided into 2 groups: midazolam group (M, n = 10) and propofol group (P, n = 10) . Patients with preoperative hepatic and renal dysfunction, coagulation defect and diabetes, primary hypertension and coronary artery disease were excluded. The patients were premedicated intramuscular morphine 0.1 mg?kg-1 and oral diazepam 0.1 mg?kg-1. Anesthesia was induced with midazolam 0.06-0.1 mg?kg-1 (group M) or propofol 1.0-1.5 mg?kg-1 (group P) and scopolamine 0.6 mg, fentanyl 4-10 ug?kg-1, vecuronium 0.1 mg?kg-1 and lidocaine 1.5 mg?kg-1, and maintained with intermittent iv boluses of midazolam 0.04-0.1 mg? kg-1 (group M) or propofol intravenous infusion at a rate of 3-5 mg?kg-1?h-1 supplemented with intermittent boluses of fentanyl and vecuronium. PETCO2 was maintained at 30-40 mm Hg during mechanical ventilation. BP, HR, ECG, CVP, PETCO2, SpO2 , nasal and rectal temperature were continuously monitored during operation. Blood samples were taken from artery before anesthesia (T1), at vena cava catheterization (T2), 30min after aortic cross-clamping (T3) and 10 min (T4), 1 h (T5), 2 h(T6), 4 h(T7) and 24 h(T8) after declamping of aorta for determination of Hct, IL-1, IL-8 and IL-10 by using ELISA. Results Plasma concentrations of IL-6, IL-8 and IL-10 were significantly increased at T4-7 as compared with the baseline value before anesthesia (T1) in both group. Plasma concentration of IL-8 in group P was significantly lower than that in group M at T7 ( P

[Objective]To explore the roles of TIDC(tumor infiltrating dendritic cell)and TIL-T(tumor infiltrating T lymphocyte)in tumor immunity of EBV-associated gastric carcinoma(EBVaGC)and their clinical significance.[Methods]TIDC and TIL-T in EBVaGC(n=49)and EBVnGC(EBV-negative gastric carcinoma)(n=20)were detected by immunohistochemistry method and then their subtypes and their relationships with clinical and pathological factors were analyzed.[Results]Mild infiltration was detected in 29 of 49(59.2%)EBVaGCs and 18 of 20(90%)EBVnGCs,while marked infiltration of TIDC was detected in 20 of 49(40.8%)EBVaGCs and 2 of 20(10%)EBVnGCs.And the difference between the two groups was significant (P=0.013).The number of TIL-T in EBVaGC was hisher than that in EBVnGC(P=0.017),and most of them were CTLs.The number of TIL-T was positively correlated with that of TIDC(r=0.386,n=49,P=0.006).The degree of TIL-T infiltration in EBVaGC had negative relationship with the lymph node metastasis(P<0.001),while TIDC had no relationship with the clinical features.[Conclusion]TIDC and TIL-T may play important roles in the tumor immunity of EBVaGC;TIDC may contribute to the TIL-T recruitment in EBVaGC.
