Objective To explore a suitable mode of prenatal ultrasound diagnosis of fetal malformations with early neonatal surgical treatment. Methods Nine fetus with surgical malformations diagnosed prenatally by ultrasound in our hospital from Mar. 1998 to Dec. 2000 were analysed. Results There were two cases diagnosed in the second trimester, 7 in the third trimester, including 1 duodeneal atresia with annular pancreas, 1 abdominal wall defect, 1 congenital diaphragmatic hernia, 1 huge omphalocele, 1 high imperforate anus, 4 hydronephrosis (2 mild and 2 severe). Six cases were operated in neonatal period, two were treated conservatively, and one did induced abortion. All cases recovered except 1 death. Conclusions The mode of prenatal ultrasound diagnosis with surgery in early neonatal period is a suitable way in China before the fetal surgery is applied. It is important to make effort to increase sensitivity of sonographic diagnosis of fetal malformation and to get early treatment in perinatal period.

OBJECTIVE To develop a rapid method for simultaneously identifying Staphylococcus aureus(SA) and its resistance against meticillin. METHODS The target strains authenicated to Staphylococcus by traditional methods(appearance,Gram-stain,catalase) first,then using Slidex~staph.plus to authenticate SA;establishing traditional method or coagulase test and ATB-ID32STAPH system for verification.The penicillin-binding protein 2a(PBP2a) was examined by Slidex MRSA Detection,establishing resistance oxacillin sieving test and mecA gene was examined by PCR for verification. RESULTS The 135 strains were positive and 321 strains were negative for Slidex~staph.plus from 456 strains.The 127 S.aureus strains and eight others were confirmed from 135 positive strains finally,11 SA strains and 310 other strains were confirmed from 321 negative strains,there were 92.0% for sensitivity and 97.5% for specificity in this method.The 52 strains PBP2a positively confirmed to meticillin-resistant S.aureus(MRSA) using Slidex MRSA Detection and 57 MRSA strains were confirmed using resistance oxacillin sieving test or PCR from 138 strains.There were 91.2% for sensitivity and 100% for specifity in this method. CONCLUSIONS The duplex Slidex~-staph monoclonal antibody examinated to SA and confirmed to MRSA has higher sensitivity and specificity.

Objective To investigate the efficacy of laparoscopic surgery for intestinal atresia in neonates.Methods A perspective study,from February 2002 to November 2006,a series of 61 newborns with intestinal atresia were randomly divided into laparoscopic and open surgery groups.The intra-and post-operative records of the two groups were compared.Results The survival rate and postoperative complications of the two groups were similar (29/31 vs 28/30,x~2=0.001,P=0.973;and x~2=1.298,P= 0.862).In the laparoscopic group,the intestine was pulled out through the umbilical trocar and then resected;the umbilical area was normal after intestinal anastomosis;no scars or only small scars were observed on the abdomen after the operation.The two groups were followed up for 6 to 18 months.During the period,3 patients showed enterocolitis (2 in the laparoscopic group and 1 in the open surgery group);3 patients developed adhesive intestinal obstruction (1 in the laparoscopic group and 2 in the open surgery group), both the complications were cured by conservative therapies.Conclusions Laparoscopic surgery is simple,safe,and effective for intestinal atresia in newborn.

Protein poly ADP-ribosylation (PARylation) is a widespread post-translational modifica-tion at DNA lesions, which is catalyzed by poly(ADP-ribose) polymerases (PARPs). This modifi-cation regulates a number of biological processes including chromatin reorganization, DNA damage response (DDR), transcriptional regulation, apoptosis, and mitosis. PARP1, functioning as a DNA damage sensor, can be activated by DNA lesions, forming PAR chains that serve as a docking platform for DNA repair factors with high biochemical complexity. Here, we highlight molecular insights into PARylation recognition, the expanding role of PARylation in DDR path-ways, and the functional interaction between PARylation and ubiquitination, which will offer us a better understanding of the biological roles of this unique post-translational modification.

Objective To study the clinical efficacy and safety of leflunomide combined with irbesartan in the treatment of lupus nephritis . Methods 80 cases of patients with lupus nephritis in Yueqing Hospital Affiliated to Wenzhou Medical University from May 2014 to May 2016 were selected and randomly divided into leflunomide group ( leflunomide combined with irbesartan group ) and cyclophosphamide group ( cyclophosphamide combined with irbesartan group),40 cases in each group.The urine indexes and blood indexes levels,clinical curative effect,adverse reaction of the two groups were statistically analyzed.Results The 24h urine protein,urine beta 2-MG,urine red blood cell count,blood beta beta2-MG,ESR,Cr levels of the leflunomide group were significantly lower (P<0.05),the serum albumin,C3 levels were significantly higher (P<0.05),the total treatment efficiency 97.5%was significantly higher than the cyclophosphamide group 82.5%(P<0.05),the incidence of adverse reactions 5.0%was significantly lower than the cyclophosphamide group 22.5%(P<0.05).Conclusion Leflunomide combined with irbesartan is safe and effective in the treatment of lupus nephritis.

Objective To explore the gender differences in patients with primary hyperparathyroidism (PHPT) concurrent with upper urinary tract stone.Methods The clinical data of 40 PHPT concurrent with upper urinary tract stone cases treated from January 1997 to December 2013 were analyzed retrospectively.There were 21 males and 19 females,with an mean age of 51 years (26-77 years).All patients underwent operation for PHPT,with preoperative parathyroid hormone (PTH) level of (38.42± 30.11)pmol/L.The PTH level in female patients was significantly higher than that in male patients (29.37± 17.64pmol/L versus 48.47±40.55 pmol/L,P=0.04).Serum biochemical variables were monitored,and 21 cases had 24 h-urinalysis.Results Postoperative pathology confirmed 36 cases of parathyroid adenoma and 4cases of parathyroid hyperplasia.Hypercalcemia and hypophosphatemia were improved with no significant gender difference (both P＞0.05).But in 21 cases of 24 h-urinalysis,urinary calcium and phosphorus in males were significantly higher than those in females (8.26±2.60 mmol/24 h versus 6.08± 1.59 mmol/24 h,P=0.03; 7.03±1.44 mmol/24 h versus 5.42±1.25 mmol/24 h,P=0.01).Conclusion In patients with PHPT concurrent with urolithiasis,male patients may be more associated with hypercalciuria.

Aim To investigate effects of berberine (Ber) on the transport of P-gp substrates including cyclosporine A (CsA) and digoxin across Caco-2 and L-MDR cell monolayers. Methods Permeability coefficients and transport rates of digoxin and CsA across Caco-2 and L-MDR1 monolayers were measured in the presence of Ber(50 ?mol?L-1~5 mmol?L-1). Results The inhibition studies for digoxin transport showed a dose-dependent decrease in basal-to-apical direction across Caco-2 and L-MDR1 monolayers in the presence of Ber (50 ?mol?L-1~5 mmol?L-1). Both a dose-dependent decrease in basal-to-apical direction and an increase in apical-to-basal direction were observed for CsA transport across Caco-2 monolayers with different concentrations of Ber. The IC50 values calculated for Ber-induced inhibition of digoxin transport are 1.44 mmol?L-1 in Caco-2 cells and 1.24 mmol?L-1 in L-MDR1 cells, respectively. The IC50 value for Ber-induced inhibition of CsA transport is 607 ?mol?L-1 in Caco-2 cells. Conclusion It was suggested that the inhibition and saturation of P-gp transport activity might be involved in interactions between Ber and CsA.

OBJECTIVE:To evaluate the efficacy and safety of Fluvastatin vs. Xuezhikang for hyperlipidemia in patients after renal transplantation. METHODS: 56 hyperlipidemia patients after renal transplantation were enrolled: 32 were assigned to receive Fluvastatin (40～80 mg) po qd for 8 weeks and 24 to receive Xuezhikang (0.6 g) po bid for 8 weeks. Total cholesterol (TC),triglyceride (TG),low-density lipoprotein-cholesterol (LDL),high-density lipoprotein-cholesterol (HDL),liver function and renal function in two groups were measured before and after treatment. RESULTS: In Fluvastatin-treated group,the TC decreased from(7.39?1.98)mmol?L-1 to(5.62?0.93)mmol?L-1,LDL reduced from(3.68?1.13)mmol?L-1 to (2.86?0.83)mmol?L-1;in Xuezhikang-treated group,TC decreased from(6.82?1.29)mmol?L-1 to (5.56?1.19) mmol?L-1 and LDL decreased from (3.26?0.73) mmol?L-1 to (2.78?0.80) mmol?L-1,all showing significant differences as compared with before treatment(P 0.05). No obvious adverse effect was noted in either group during treatment. CONCLUSION: Both Fluvastatin and Xuezhikang are safe and effective for hyperlipidemia in patients after renal transplantation.

Objective:To study the effect of cyclosporin A based triple immunosuppressive therapy on the plasma glucose in renal transplant recipients.Method:680 renal transplant recipients treated with cyclosporine A combined with prednisone and mycophenolate mofefil from Jan.1996 to May 2007 were analysed.Result:The morbidities of impaired fast- ing glucose,impaired glucose tolerance and post-transplantation diabetes mellitus (PTDM) were 3.97%,5.15% and 8.09%,respectively.The daily doses and concentrations of CsA and the daily doses of prednisone in the impaired glucose tolerance group and PTDM group were significantly higher than those in the normal plasma glucose group.Conclusion:The daily doses and concentrations of CsA and the daily doses of prednisone were closely related to the impaired glucose toler- ance and PTDM of renal transplant recipients.

BACKGROUND:Previous studies have found that the susceptibility genes of adiponectin gene and calpain 10 gene of type 2 diabetes are closely related with the incidence of diabetes in Chinese renal transplantation patients. So, are other susceptibility genes of type 2 diabetes also associated with posttransplantation diabetes mel itus? OBJECTIVE:To investigate the association between the zinc transporter solute carrier family 30 member 8 (SLC30A8) gene polymorphism and the posttransplantation diabetes mel itus. METHODS:A total of 97 patients with posttransplantation diabetes mel itus and 301 patents without posttransplantation diabetes mel itus (control group) were selected, and then the SLC30A8 gene rs13266634 genotype was detected with real-time PCR method. The association between gene polymorphism and posttransplantation diabetes mel itus was analyzed with Logistic regression test. RESULTS AND CONCLUSION:There were significant differences in al ele frequencies and genotype distributions of rs13266634 between the patients with and without posttransplantation diabetes mel itus (P<0.05). After adjustments of age, sex, body weight and body mass index, the incidence of posttransplantation diabetes mel itus of the CC genotype patients was 2.108 times to that of the TT genotype patients (odds ratio=2.108, 95%confidence interval:1.075-4.131, P=0.044);and the incidence of posttransplantation diabetes mel itus of the CC+CT genotype patients was 1.862 times to that of the TT genotype patients (odds ratio=1.862, 95%confidence interval:1.049-3.306, P=0.034). The results suggest that the C-al ele in rs13266634 of SLC30A8 gene is the independent risk factor of posttransplantation diabetes mel itus.
