Objective:To find the rate of anxiety and depression in peritoneal dialysis (PD) patients,and the relationship between these emotion disorder and PD processes.Method:88 PD patients were studied, their mood state was evaluated with Hamilton Anxiety Scale and Hamilton Depression Scale. Nutritional indexes, residual renal function and dialysis adequacy, and inflammation status were also recorded as well as history of cardiac-cerebral vascular disease. These patients were followed for 2 years.Result:44.3% patients were detected as anxiety, and 56.8% depression. Higher SGA was associated with higher Hamilton anxiety/depression scale. Patients with higher anxiety and higher depression had lower serum albumin, lower protein intake, lower body index, and lower mid-arm muscle area and fat area. Anxiety and depression is related to cardiac-cerebral vascular diseases and diabetes.There was no significant relationship between Hamilton anxiety/depression score and patient's survival.Conclusion:There is a high rates of anxiety and depression in PD patients and it may be a potential risk factor of malnutrition.

Objective To explore the molecular effect and interaction among nephrin, podocin, CD2AP and ?-actinin-4. Methods Firstly, the recombinant RNA interference (RNAi) plasmid-psiRNA-hH1GFPzeo, specifically targeting to the mRNA of nephrin, podocin, CD2AP or ?-actinin-4, was respectively tansfected into the mouse podocyte clone (MPC5) to each knockdown (KD) the expression of nephrin, podocin, CD2AP or ?-actinin-4. Molecular distributions were revealed by confocal microscopy, and the mRNA and protein expressions were detected with semi-quantitative RT-PCR and Western blotting. Results (1)In podocin KD group (siPod966 and siPod54), the mRNAs of podocin and nephrin were not detected, their protein decreased 92% and 79%, 82% and 67%, respectively. The mRNA and protein level of CD2AP increased 62% and 42%, 71% and 46%, respectively, whereas ?-actinin-4 did not change. In nephrin KD group (siNep492), the mRNA expression and protein level of nephrin were not detected, CD2AP increased 35% and 48%, respectively; and whereas podocin and ?-actinin-4 did not change. In CD2AP KD group (siCda744 and siCda21), the mRNA of expression CD2AP was not detected, and its protein level decreased 92% and 83%, the mRNA and protein of nephrin decreased 60% and 48%, 76% and 72%, respectively; podocin increased 38% and 22%, 56% and 44%, respectively; whereas ?-actinin-4 did not change. In ?-actinin-4 KD group (siAct1790 and siAct319), the mRNAs expression of ?-actinin-4 and nephrin decreased 69% and 58%, 64% and 49%, respectively; their protein level decreased 81% and 55%, 71% and 64%, respectively. However, the mRNAs of podocin and CD2AP increased 50% and 34%, 45% and 28%, respectively; and their protein level increased 64% and 46%, 65% and 42%, respectively. (2) With their expression change, the distributions of nephrin, podocin and CD2AP shifted evidently from the cell membrane surface to the nucleus circumference, whereas ?-actinin-4 showed no change, which was still localized in the cytoplasm and further extended to foot processes. Conclusion (1) Nephrin might more independently play a crucial role in the slit diaphragm complex. (2) Alpha-actinin-4 might interact direcdy or indirectly with nephrin, podocin and CD2AP. (3) The relationship among these podocyte molecules might not be spontaneous, either a single-directional or bi-directional reaction. (4) The normal localization of these podocyte molecules might depend on their normal expression quantity.

Objective To evaluate the efficacy of metformin(MTF) in treatment of clomiphene (CC)-resistant patients with polycystic ovary syndrome (PCOS).Methods The published articles of randomized controlled trial (RCT) of comparison of MTF combined with CC and CC alone in treatment of CC-resistant PCOS were searched in PubMed,EMBASE,OVID,EBSCO databases and Cochrane Library,and these studies were screened under inclusion and exclusion criteria.The quality of included studies and extract data of comparison of ovulation rates and pregnancy rates were evaluated.And the Meta-analysis using statistic software RevMan 5.0 was completed.ResultTotal of 333 patients in total 8 trials were included.Meta analysis showed that MTF plus CC led to a significantly higher clinical ovulation rate ( OR =7.31,95 ％ CI:2.57 - 20.76,P ＜ 0.05 ) and pregnancy rate ( OR =7.93,95 ％ CI:2.45 - 25.63,P ＜ 0.05 ) than that of CC alone.Conclusion MTF can increase ovulation and pregnancy rates of CC-resistant PCOS women.

Objective To observe the effects of acetyl-l-carnitine (ALC) on autophagy, apoptosis and motor function after acute spinal cord injury (ASCI) in rats. Methods Thirty-six adult female Sprague-Dawley rats were randomly divided into sham operation group (Sham group, n=12), simple spinal cord injury group (SCI group, n=12), ALC treatment group (ALC group, n=12). Spinal cord injury model at the level of T10 segment was established using Allen's method. They were assessed with Basso-Beattle-Bresnahan (BBB) scale three days after injury. Then the rats were sacrificed, and the expression of microtubule associated protein 1 light chain 3 (LC3)-II in spinal cord was detect-ed with Western blotting and immunofluorescent labeling, and the number of apoptotic cells were assessed with TUNEL staining. Results The expression of LC3-II and the number of apoptotic cells increased in SCI group compared with those in Sham group (P<0.01), while the BBB score decreased (P<0.001). The expression of LC3-II increased and the number of apoptotic cells decreased in ALC group compared with those in SCI group (P<0.001), while the BBB score increased (P<0.01). Conclusion ALC may promote autophagy, and inhibit apopto-sis to improve the locomotor function after ASCI.

Objective To explore the molecular mechanisms underlying therapeutic responses of the anti-proteinuria drugs from the view of podocyte molecule. Methods Adriamycin (ADR) nephropathy was induced by a single tail intravenous injection of adriamycin. Lisinopril, prednisone and all-trans retinoic acid (ATRA) were administered once a day to the adriamycin-induced nephrotic rats at the first day after adriamycin injection respectively. Renal tissue samples were collected at day 3, 7, 14, and 28 after adriamycin injection respectively. The distribution, mRNA expression and protein expression of nephrin, podocin, CD2AP and ?-actinin-4 were examined by indirect immunofluorescence, real-time PCR and Western blotting, respectively. The interactions among nephrin and podocin, nephrin and CD2AP, as well as the nephrin phosphorylation were detected by immunoprecipitation, respectively.

Objective To analysis the clinical effects of biliary-pancreatic double stents in pancreatic cancer patients with obstructive jaundice.Methods From July 2008 to October 2011,a total of 60 patients with advanced pancreatic cancer were randomly divided into two groups to receive biliary-pancreatic double stents (n =28) or biliary stent only (n =32) according to the odd and even numbers of their admission date.Changes in liver function,abdominal pain,quality of life scores (QOL) were compared between two groups.Results The stents were placed successfully in 54 patients (90.0％),in which symptoms were relieved or gradually disappeared in all patients after the procedure.One week after stents placement,the serum total bilirubin decreased significantly from 164.32 ±45.16 μmol/L before ERCP to 63.25 ±27.06 μmol/L (P ＜ 0.05),other parameters including ALT,AST,AKP and r-GT were also decreased significantly compared with those of pre-ERCP (P ＜ 0.01),but there was no significant difference between the two groups (P ＞ 0.05).25 cases in double-stents group and 29 cases in single-stent group had varying degrees of pain relief at 7d after ERCP,but the overall pain relief rate and complete pain relief rate in double-stent group were significantly higher than those in single-stent group (92.0％ vs.55.2％; 64.0％ vs.34.5％,P＜0.05).At 7d and 14d after ERCP,Karnofsky QOL score were improved significantly in double-stent group (P ＜ 0.05).It was significantly better than single-stent group at 14d after ERCP (P ＜0.05).No death or other severe ERCP-related complications were observed.Conclusion Biliary-pancreatic stent placement for pancreatic cancer could significantly improve liver function and relieve obstructive pain.In the ways of alleviating pain and improving quality of life scores,it was better than ERCP biliary stent placement,especially for patients with pancreatic cancer combined obstructive pain.It indicated that biliary-pancreatic stent placement was better than simple biliary stent placement for advanced pancreatic head cancer patients with obstructive pain.
