Background and purpose:MMMT is known as a rare malignancy in gynecological tumor. Because of its difficulty in diagnosis and treatment, the prognosis is extremely poor. This study was to discuss the clinicopathologic feature and PRA,PRB expressions of uterine MMMT. Methods:We analysed clinicopathologic data and the expressions of PRA,PRB by immunohistochemical staining on 17 cases of uterine MMMT, and 11 patients were followed up. Results:①The patients usually presented with abnormal vaginal bleeding with no specifi city clinically. ②The morphological changes were various and complicated, including epithelial and mesenchymal components and a variety of inter-permeated and transitional tissue elements.③The positive rate of PRA in stageⅠ and stageⅡ were 66.7% and 40%, and PRB in stage Ⅰ and stageⅡwere 55.6% and 20%, respectively. ④The mean survival time in stageⅠ,Ⅱ and Ⅲ were 43.8 months (32-59), 34.25 months (19~41) and 5 months, respectively. Conclusion:The diagnosis of uterine MMMT was mainly based on tissue morphology; the development of uterine MMMT might be related with the loss of PRA and PRB ; the clinical stage and the expression of PRA and PRB might be the prognostic factors for uterine MMMT.

OBJECTIVE To investigate the characteristic of multidrug resistant organisms(MDROs) in hospital or community-acquired infection,so that it can approach effective infection management.METHODS Patients infected by Staphylococcus,Enterococcus,Escherichia coli,Klpneumoniae and A.baumanni were investigated in a Hospital from June 2008 to May 2009.RESULTS Among total 929 strains of bacilli from patients,367 were MDROs infection,the detection rate of MDROs,CA-MDROs or HA-MDROs was 39.5%,35.6% and 51.4% respectioety infection;The detection rate of MDROs from HAI patients was significantly higher than that from CAI patients(?2=19.2 P=0.00).There were differences between HA-MDROs and CA-MDROs in different departments.MRSA,ESBLs-kp And PDR-AB were isolated mostly from sputum of patients,and ESBLs E.coli mostly from urine of CAI patients.CONCLUSIONS It is important to analyze the characteristic of HA-MDROs or CA-MDROs in the treatment of infection or use of antibiotics from experience.MDROs control is full of difficulties as a result of high CA-MDROs rates.

The changes in the tau protein phosphorylation and expression of bcl-2, and bax in rat parietal cortex neurons after focal cerebral ischemia-reperfusion (I/R) were explored, and the relationship between the tau protein phosphorylation and the expression of bax or apoptosis was clarified in order to elucidate the relationship between cerebral infarction and Alzheimer's disease. The rat focal cerebral I/R model was induced by occlusion of the right middle cerebral artery using the intraluminal suture method. The level of tau protein phosphorylation at Ser396, Ser404, Tyr231, Ser199/202 sites and the expression of bcl-2, bax and total tau 5 in rat parietal cortex during focal cerebral ischemia/reperfusion were detected by Western blot. The relationship between the tau protein phosphorylation and the expression of bax, or apoptosis was examined by TUNEL method and double-labeling immunofluorenscence method. The results showed that the level of tau hyperphosphorylation at Ser199 / 202, Ser396, Ser404, Tyr231 sites and the expression levels of bcl-2, and bax were significantly higher in I/R group than in the sham group, but the ratio of bcl-2/bax was decreased. Neuronal apoptosis, bax expression and the tau protein hyperphosphorylation were co-localized. It is suggested that Alzheimer's disease-like pathological changes occur after cerebral I/R. The highly abnormal phosphorylation of tau protein plays a key role in cerebral I/R-induced apoptosis. The cerebral infarction may contribute to Alzheimer's disease occurrence and development.

Objective To investigate the nutritional risks, undernutrition, and nutritional support among inpatients in tertiary hospitals in Tianjin using Nutritional Risk Screening 2002 (NRS2002). Methods Inpatients in six departments in two tertiary hospitals in Tianjin (Tianjin Nankai Hospital and Tianjin Chest Hospital ) were consecutively enrolled from March 2005 to March 2006. Their nutritional risks were screened using NRS 2002, and the nutritional support was investigated. Results A total of 1200 inpatients received nutritional screening, and 93.0% of them underwent NRS 2002 scoring. The prevalence of undernutrition was 9. 8% and the prevalence of nutritional risk was 42. 8%. Of these patients, 241 patients (46.4%) with NRS2002≥3 received nutrition support, and 244 patients (35.9%) with NRS2002 ＜3 received nutritional support Conclusions NRS2002 is suitable for nutritional risk screening among inpatients. Inpatients usually have nutritional risks or undernutrition. However, physicians at different levels in different regions have different awareness of such risks or conditions, and the clinical application of nutritional supports sometimes are inappropriate.

Objective To investigate the effects of functional electrical stimulation (FES) on motor function and the expression of bromodeoxyuridine (Brdu) + and glial fibrillary acid protein (GFAP) + in the subventricular zone (SVZ) of rats with acute cerebral infarction,and to explore it's mechanism. Methods A rat model of cerebral infarction was established using Longa's technique for middle cerebral artery occlusion (MCAO) with an intraluminal filament.The rats were randomly divided into a FES group,a placebo stimulation group and a control group.In each group,rats were randomly allocated into 1 d,3 d,7 d and 14 d subgroups (6 rats/subgroup).Superficial electrodes were pasted on the paralyzed forelimbs of rats in the FES group for connecting with the FES instrument,and FES treatment was carried out with a current of 4-5 mA for 15 min on the third day after the MCAO operation to produce extension of the wrist and the digits of the paralyzed forelimb.The rats in the placebo stimulation group were pasted with electrodes,but no FES was administered and they received no other treatment.Neurological deficits were evaluated using the modified neurological severity score (mNSS) before treatment and on the 1 st,3rd,7th,and 14th day after treatment. BrdU and GFAP positive cells in the SVZ were detected by immunofluorescence techniques.Results After 7 or 14 days the motor function of rats in the FES group had improved significantly compared with the placebo stimulation and control groups.Compared with the other two groups,the expression levels of BrdU+ and GFAP+ cells in the ischemic SVZ in the FES group were significantly higher at the 3rd,7th and 14th day.Conclusion FES can improve motor function after acute cerebral infarction and also promote the proliferation and differentiation of neural stem cells in the SVZ.

Objective To explore the method for detecting the connexin 43(Cx43) in detrusor of bladder in rats with detrusor instability.Methods The model of rats with detrusor instability was established.Ten rats in unstable bladder group were determined by filling cystonetry method controlled by 10 normal rats.The fluorescein isothiocyanate(FITC) was used to label the Cx43 and the tritin conjugated rhodamine was used to label the cell membrane of detrusor muscle.The Cx43 and the cell membrane of detrusor muscle were detected by laser scanning confocal microscopy(LSCM),and the images were analyzed by the image analysis program.Results The distinct images of Cx43 and cell membrane of detrusor muscle could be obtained by the LSCM.The expression of Cx43 and pixel density were increased significantly in rats of unstable bladder group than those of the control group(all P

Objective To study the effect of rice oil on secretory immunoglobulin A (sIgA) content in feces and disease outcome in children with acute diarrhea.Methods We selected 180 children with acute diarrhea hospitalized in Tianjin Children's Hospital during the period from January 2013 to October 2014.They were randomly divided with a random number table into rice oil group,montmorillonite powder group and control group (all n =60).The effect of treatment,duration before subsiding of diarrhea and vomit,length of hospital stay and sIgA content in feces before and after treatment were analyzed.Results The total effective rates in the rice oil group and the montmorillonite powder group (93.3％,96.7％) were significantly higher than that in the control group (76.7％,P =0.011,P =0.001).Length of hospital stay,duration before subsiding of diarrhea and vomit in the rice oil group and the montmorillonite powder group were significantly shorter than those in the control group[(5.6±1.4) d,(5.7±1.6) d vs.(6.9±1.8) d;(3.7±0.9) d,(3.5±0.9) d vs.(5.4±1.2) d;(2.8 ± 0.6) d,(3.2 ± 0.8) d vs.(5.1 ± 0.8) d;all P =0.000].The total effective rates,length of hospital stay,duration before subsiding of diarrhea showed no statistically significant differences between the rice oil group and the montmorillonite powder group (P =0.402,0.716,0.226),but the duration before subsiding of vomit in the rice oil group was significantly shorter than that in the montmorillonite powder group (P =0.016).Before treatment,the sIgA contents in feces in the control group,the montmorillonite powder group,the rice oil group were 0.527 ± 0.133,0.487 ± 0.109,0.534 ± 0.150,with no significant difference (P ＞ 0.05).Two days after treatment,sIgA contents in the rice oil group and the montmorillonite powder group (0.669 ±0.176,0.612 ± 0.161) were significantly higher than in the control group (0.541 ±0.149,P =0.000,0.014).There was no significant difference between the montmorillonite powder group and the rice oil group (P =0.067).Four days after treatment,sIgA content in the montmorillonite powder group (1.981 ±0.462) was significantly higher than in the control group (1.762 ±0.378,P =0.005),while sIgA content in the rice oil group (2.331 ± 0.494) was significantly higher than in the other 2 groups (P =0.000).Compared with the levels before treatment,sIgA content 2 days after treatment was not significantly changed in the control group (P =0.295),but was significantly elevated in the montmorillonite powder group and the rice oil group (both P =0.000).sIgA contents of all the three groups 4 days after treatment were significantly higher than the contents 2 days after treatment (all P =0.000).Conclusion The effect of rice oil on acute diarrhea in children is as same as that of montmorillonite powder,and may be better in mitigating vomit and promoting the secretion of intestinal sIgA.
