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.

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.

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.

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.

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.

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.

Objective To explore the clinical effect of the elderly far lateral lumbar disc herniation via Quadrant channel system under the Wiltse approach. Methods Thirty-three elderly patients suffering from far lateral lumbar disc herniation were treated by surgery, among whom 18 patients were treated by Quadrant minimally invasive channel system (Quadrant group), and 13 patients were treated by percutaneous transforaminal endoscopic discectomy (PTED group). The patients were followed up for 12 months, and the operation time, blood loss and length of incision were investigated. The JOA scores were compared preoperatively and postoperatively. Results The patients in two groups were followed up for 24 months, except 1 patient withdrew in Quadrant group. The incision length and blood loss in PTED group were superior to those in the Quadrant group:2.0-2.5 cm vs. 0.7 cm, (46.50± 15.20) ml vs.(23.87±6.58) ml, P<0.01, but the operation time in PTED group was longer than that in Quadrant group: (77.17 ± 8.71) min vs. (63.20 ±10.87) min, P<0.01.The two groups had achieved good curative effect, while JOA score in PTED group was superior to the Quadrant group 1 week after operation ( P<0.05), but in 3 month and 12 month two groups had no significant difference ( P>0.05). Conclusion Surgical treatment on elderly far lateral lumbar disc herniation via quadrant channel under wiltse approach is an effective method, and can achieve similar effect with PTED.

Objective To explore the histological properties of isolated chondrons and chondrocytes from rabbit knee cartilage,and to determine if these properties vary with age.Methods Three groups of rabbit knees were evaluated according to different age:(1) young (2 months,n=10);(2) adult (8 months,n=10);and (3) old (31 months,n=10).The cartilage structure,proteoglycan,collagen-2,and collagen-6 content were determined by light microscopic using hematoxylin-eosin (HE),Toluidine Blue,and col-2,6 staining.The chondrons were enzymatically isolated using 0.3 g/L dispase and 0.2 g/L collagenase-2 by shaking for 3 hours.The morphology and composition of isolated chondrons were observed by HE and collagen-6 immunostaining staining after overnight coverslip monolayer culture under a microscopy.Results The chondrocytes became sparser and the total content of proteoglycans and collagen-2 were decreased in the articular cartilage with age.Compared to the chondrocytes,the surrounding rim or capsule was more obvious in the isolated chondrons,and they exhibited obvious differences in shape.The cells within one cluster from different age groups were similar to the morphology observed in cartilage in situ.The adult and old chondrons generally possessed a thicker pericellular matrix with more enclosed cells,and the chondrons contained more cells can reach 47％.Conclusion These findings further suggest that the properties of the chondrons and pericellular matrix have an important influence on the biomechanical microenvironment of the knee joint cartilage degeneration that occurs with age.
