Objective To analyse the encoding gene sequence of extended spectrum ? lactamase produced by Klebsiella pneumoniae E95 strain in Zhejiang Province and identify its ESBLs subtype. Methods The gene of ESBLs produced by E95 strain was amplified by PCR. The purified PCR product was cloned into pGEM Teasy vector and then sequenced by Sanger's dideoxy chain termination composition method. Results The encoded gene of ESBLs was identified as SHV by PCR. Its PCR product had 812 nucleotides. It had the same gene sequence as the gene encoding SHV 12 discovered in Swiss. Conclusions The ESBLs produced by Klebsiella pneumoniae E95 strain isolated from a patient in Zhejiang Province is SHV 12.

Survivin is a member of the IAP family, which has been shown to localize to various components of the mitotic apparatus. Survivin is not only an apoptosis inhibitor, but a mitotic regulator as well. Survivin is Absolutely undetectable in normal tissues, but over-expressed in all the most common human cancers. Survivin is considered as an important target in cancer treatment, and the research on its molecular antagonists has gained encouraging achievements.

Objective Pneumoperitoneum is usually the result of hollow visceral perforation and requires emergent laparotomy.However,about 10% of patients lack a pathologic cause requiring surgical intervention and can be resolved with conservative management.The aim of this study is to discuss the indications for conservative management of pneumoperitoneum in children.Methods We retrospectively reviewed the data of 5 children with pneumoperitoneum without peritonitis treated in our pediatric surgery department between January 2009 and December 2010.Results There were 5 children with an average age 5.4 years.Radiologic examinations demonstrated pneumoperitoneum and visceral perforations were suspected in the local hospitals.The abdominal examination revealed no peritoneal signs in all patients.Among them,peritoneal aspirations were implemented in 4 patients and the results were negative.One of five patients underwent laparotomy that demonstrated no visceral perforation.The remaining four were successfully managed conservatively and the pneumoperitoneum was completely resolved between 3 and 9 days.All children were without abdominal symptoms and signs throughout at least 2 years follow-up.Conclusion The presence of free intraperitoneal air does not always indicate hollow visceral perforation and the need for emergent laparotomy.It appears that therapeutic effectiveness can be readily achieved with conservative management in children with pneumoperitoneum without peritonitis.

Intestinal flora is an important component of the body and is closely related to the health of infants and toddlers.There are many hypotheses about the origin and establishment mechanism of intestinal flora, but most theories are still controversial.The intestinal flora is not static, and its biodiversity and abundance will continue to differentiate and evolve with the growth and development of nurslings.It is now believed that intestinal flora plays a variety of roles in maintaining the homeostasis of the infant's internal environment.This review summarizes the basic research on the physiology of infantile intestinal flora in recent years, to provide some reference for the development of this branch in the field of pediatrics.

The First Affiliated Hospital of Zhejiang University founded an online hospital campus leveraging the Internet-plus environment. Supported by the offline hospital, this campus made full use of Internet features and advantages in its attempts to optimize the distribution of medical resources,to improve the accessibility of medical service, to reduce medical costs, and to expand the service coverage among others. Meanwhile,this online system, via interconnection with the hospital′s HIS system, achieved online medical insurance payment,prescriptions checking and drug delivery service.

Objective To explore the feasibility of coelocentesis in prenatal diagnosis.Methods Coelocentesis were applied on 58 women scheduled for at 6~12 weeks of gestation,and fetal heart rate before the procedure and 1,5,30 minutes afterwards and hemorrhage of amnionic cyst was observed.Y gene of sex-determining region was detected by polymerase chain reaction,and compared with chorionic villi sample.Results The total achievement ratio of coelocentesis was 96.6% of all cases in five minutes.The coelomic fluid was successfully aspirated at first attempt in 93.2% at 7~10 week's gestation,25.0% at 6~7weeks and 50.0% at 10 ~ 12 weeks.There was no significant difference in FHR between before coelocentesis and afterwards (P>0.05).The detection accurate rate of SRY was 91.1%,all female fetus were matched with those observation by chorionic villi sampling,and only 5 male fetus were not matched,the accurate rate was 80.8%.Conclusion Coclocentesis has the advantage of simple procedure,safe and high feasibility.The optimal time of coclocentesis is in the 7th to 10th week of gestation.

Objective To investigate the effects of advanced oxidation protein products (AOPP) in type 2 diabetic ocular muscles palsy (DOMP). Methods 58 DOMP patients and 50 type 2 diabetes patients were included in the research. Hemoglobin A1c (HbA1c), blood glucose (FPG), fasting insulin (FINS) and triglycerides (TG), total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL) were measured and recorded. Homeostasis model assessment was performed to evaluate the status of insulin resistance (HOMA-IR), basal insulin secretion (HOMA-β) and the insulin sensitivity index (ISI). Serum AOPP was measured by enzyme linked immunosorbent assay. Unconditional logistic regression model was used to evaluate the influencing factors of DOMP. Results The DOMP group showed higher levels of plasma AOPP, TG, LDL, FPG, FINS, HbA1c and HOMA-IR, but lower levels of HDL, HOMA-β and ISI than those of the T2DM group. Unconditional logistic regression analysis revealed that AOPP was an independent risk factors for DOMP (OR =3.01, P = 0.002). Conclusion AOPP may be involved in the pathogenesis of DOMP. AOPP could be a useful indicator for monitoring the development of DOMP and for evaluating its severity.

Objective To explore the change of glyoxalase I in type 2 diabetic ocular muscles palsy (DOMP) and its associations with advanced oxidation protein products (AOPP) and oxidative stress. Methods 58 DOMP patients, 50 T2DM and 30 normal controls were enrolled in this study. Levels of blood lipids, fasting blood glucose, hemoglobin A1c, insulin, serum glyoxalase I, AOPP, malondialdehyde (MDA), superoxide dismutase (SOD) and total antioxidant capacity (T-AOC) were measured. Homeostasis model assessment was performed to evaluate the status of insulin resistance (IR). Results Levels of high-density lipoprotein cholesterol, SOD and T-AOC were positively correlated with glyoxalase I and inversely associated to AOPP. Levels of triglycerides , low-density lipoprotein cholesterol , fasting blood glucose , hemoglobin A1c , IR and MDA were negatively correlated with glyoxalase I and positively related to AOPP. AOPP had an inverse association with glyoxalase I (r = -0.823, P < 0.001). Multivariate regression analysis showed that serum levels of glyoxalase I (Sβ = 0.554) and AOPP (Sβ= -0.469) were influencing factors of groups. Conclusion Serum glyoxalase I levels were significantly decreased in DOMP and correlated with AOPP and levels of oxidative stress , which suggest that glyoxalase I could play crucial roles on the development of DOMP.
