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 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.

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.

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.

Objecfive To study the effect of fibronectin(FN)and arginine-glycine-aspartateserine tetrapeptide (RGDS)on chemotherapy sensitivity of hepatocellular carcinoma(HCC)cell lines.Methods A HCC cell lines 7721 was divided into BSA group(BO),FN group(FO),RGDS group(RO)and FN+RGDS group(FR).Mitomycin-C(MMC)was added into each group with different concentrations for 2 h,12 h and 24 h.MTT assay was used to detect the survival rate of the tumor cell at different time,and fluorescent staining method and flow cytometry was used to detect the tumor cell's apoptosis.Results The survival rate and apoptosis rate was significantly different between each group with the treatment of MMC for 12 h or 24 h,and no statistical difference was found after incubation for 2 h.Conclusions With time FN down-regulates MMC induced apoptosis of the HCC cells.making HCC cells 1ess sensitive to chemotherapy,while RGDS enhances the sensitivity of HCC cells to chemotherapy.

Objective To discuss the value of intrapartum operation in management of birth defects and the prognosis. Methods From August 2008 to November 2009, 11 fetuses were identified with birth defects through 3D color Doppler ultrasound and confirmed by MRI and fetal karyotype in the Maternal Fetal Medicine Center, Affiliated Shengjing Hospital, China Medical University including three lymphangiomas,two congenital diaphragmatic hernias (CDH), one sacrococcygeal teratoma, three omphalocele and two gastroschisi. All the above identified birth defects were indications for surgery. All fetuses were born abdominally and received intrapartum operations, including three intrapartum fetal operations with placental infusion (two repairs of CDH, one sacrococcygeal teratoma resection), six ex-utero intrapartum treatment (EXIT; two repairs of omphalocele, two repairs of gastroschisi, two lymphangioma resection) and two surgeries in house (one omphalocele repair and one lymphangioma resection). Both the mothers and fetuses were regularly followed up. Results ( 1 ) Operations: the average operating time for the three intrapartum fetal operations was 89 minites, 5.5 minites for the six EXIT, during which EXIT was performed first,followed by blocking the umbilical circulation and neonatal surgery, and 37 minites for the two surgeries in house. All neonates survived except for one death from severe CDH at 3.5 hours after the operation. The average blood loss for cesarean section and fetal operation was 275 ml. All mothers recovered soon without fever or infection and were discharged three to five days after the operation. (2) Follow-ups: the ten survived neonates were followed up at 1 - 18 mouths at the pediatric clinics and all were growing and developing normally except for one baby with gastroschisi suffered from enteral torsion and feeding intolerance showed lower weight than babies at the same age, but catched up to normal at four months old after posture therapy. One baby with mild CDH developed pulmonary infection at two months after operation with 1/4 pneumothorax on chest X-ray, and were hospitalized for two weeks. At six months old, patent ductus arteriosus was diagnosed in the same baby and chest X-ray was normal. The baby with omphalocele was complicated with ventricular septal defect before operation and the cardiac function was normal during followups for one year. The baby with sacrococcygeal teratoma was reported to have no automatic micturition, but recovered to normal at one month of age. Conclusion Babies with certain birth defects can be managed through intrapartum operation with better outcomes.

To study the possible mechanism of the effect of glucagon-like peptide-1 (GLP-1) on injury to neonatal rat cardiomyocytes induced by hypoxia-reoxygenation. Lactate dehydrogenase activity [(210.0±11.5) vs (101.4±6.5) U/L] ,apoptosis rate [(8. 138±1. 512) vs(0. 575±0. 168)%] ,and caspase-3 activity [(44.52± 5.69)vs(19.98±1.97) ,all P<0.01] were all increased after hypoxia-reoxygenation. GLP-1 appears to directly act on cardiomyocytes and to protect them from hypoxia-reoxygenation injury [lactate dehydrogenase (190.2±9.0) U/ L, apoptosis rate (2.688±0.580) %, caspase-3 activity 30.34±4.18] mainly by inhibiting the apoptosis probably via the PBK/Akt signaling pathways.

Objectives:To assess bowel function and quality of life in patients with ulcerative colitis (UC)after ileal pouch anal anastomosis (IPAA).Methods:Clinical data of 37 UC patients after IPAA between 2014 and 2017 were retrospectively analyzed at Sir Run Run Shaw Hospital School of Medicine Zhejiang University. The IBDQ and Bowel Function questionnaire were used for analyzing correlation between clinical variables and quality of life or bowel function.Results:Laparoscopic operation was performed in 12 cases at stage 2 and 25 cases at stage 3. Postoperative defecation of stage 3 patients were better than that of stage 2 ( t=6.72, P<0.05). The number of daily defecation in age >45-year-old group was more than that in <45-year-old ( t=3.49, P<0.05), and the rate of evening stool seepage in the older group was higher than in the younger group( t=5.28, P<0.05). The total score of intestinal symptoms of IBDQ in patients of pouchitis was lower than that without pouchitis ( r=0.330, P<0.05). The total score in age >45 in terms of systemic symptoms ( r=0.349, P<0.05) and emotional function ( r=0.379, P<0.05) was higher than age <45. Conclusions:Outcomes of UC patients after IPAA are satisfactory, bowel function and quality of life is related with age, and stage of IPAA affect postoperative defecation.
