Objective To explore the clinical diagnosis and treatment of pediatric bridging bronchus deformity and brid-ging bronchus with pulmonary artery sling. Methods The clinical data of the 21 cases of diagnosed bronchial bridge deformity and bronchial bridge with pulmonary artery sling, the imaging findings of all the echocardiography, MSCT chest scan, enhanced CT and reconstructive image were retrospectively analyzed. Results In 21 cases, 10 were diagnosed as bronchial bridge only, among which three cases had other types of congenital heart disease;11 cases were diagnosed of pulmonary artery sling with pulmonary artery sling, among which 8 cases had other types of congenital heart disease;their average age of the 8 cases were all younger than 2 years old, except one case;most of them had the symptoms of recurrent respiratory tract infections and parox-ysmal dyspnea. According to Wells, bronchial bridge was divided into type I and typeⅡ;15 cases were type I, 6 cases were typeⅡ, 10 patients with bronchial bridge only were all type I, 5 cases of typeⅡwere associated with pulmonary artery sling. All of the 6 cases were diagnosed as typeⅡassociated with pulmonary artery sling. Conclusions Infants and young children with clini-cal recurrent respiratory tract infections should be considered the possibility of bronchus bridge deformity, and should be paid more attention to the possibility of pulmonary artery sling. MSCT plain chest scan, enhanced CT and airway reconstructive im-age are the important ways to diagnose the disease.

Antiphospholipid antibodies (APLs) are important for the diagnosis of antiphospholipid syndrome (APS),especially for predicting the risk of thrombosis and pathological pregnancy.However,the heterogeneity of antiphospholipid antibodies,lacking of standardization and significant interlaboratory variation binder the clinical application of APLs and better understanding of APS diagnosis and treatment.Therefore,it is urgent to establish a standardize system for antiphospholipid antibodies test and to improve the performance of the test and perform well-designed clinical evaluation.

According to the consensus criteria of antiphospholipid syndrome (APS),the diagnosis of APS requires the persistent presence of antiphospholipid antibodies (aPLs),indicating the critical role of aPLs in the diagnosis of APS.During the last decade,great efforts have been made to improve the laboratory detection and standardization of aPLs testing.Unfortunately,the heterogeneous nature of aPLs,lacking of standardization in aPLs test,and significant inter-laboratory variation have hampered the clinical application of aPLs test.In this commentary,the clinical application and standardization of aPLs test are focused on,and how to establish the standardization system in aPLs test in order to improve the performance of aPLs test in clinical practice are discussed.

Objective To investigate the effects of Xuebijing injection on T-lymphocyte subgroups and clinical efficacy in treatment of patients with severe pneumonia.Methods 60 patients with severe pneumonia were selected into the study.The patients were randomly divided into Xuebijing group (n =30) and control group (n =30).Patients in the control group were given routine therapy.The Xuebijing group received the treatment of routine therapy combined with Xuebijing injection.The changes of T lymphocyte subgroups and clinical efficacy were compared between the two groups.Results The levels of CD3,CD4,CD4/CD8 after treatment in Xuebijing group and control group were significantly higher than those of before treatment (t =4.95,4.89,4.96,3.13,3.11,3.09,all P ＜ 0.05),those in the Xuebijing group were significantly higher than control group (t =3.89,3.56,3.78,all P ＜ 0.05).The total effective rate in the Xuebijing group was 93.3％,which was significantly higher than 76.6％ in the control group (x2 =4.55,P ＜ 0.05).Conclusion Xuebijing injection combined with routine western medicine is quite effective in treatment severe pneumonia.Xuebijing can improve the immune function of patients.

Objective To detect COX-2 mRNA in cervical cancer and normal cervix, and explore the pathogenesis of adenocarcinoma of the uterine cervix. Methods COX-2 expression was detected by RT-PCR to explore the relationship between COX-2 and the adenocarcinogenon of cervical cancer in 36 cases of adenocarcinoma of the uterine cervix and 15 cases normal cervical tissue. Results The positive rate of COX-2 mRNA in adenocarcinoma of the uterine cervix tissues (55.6%) was higher than that of normal tissues ( 20. 0% ), the difference was significant ( P ＜ 0. 05). The expression of COX-2 mRNA was associated with stages and clinical grading of tumor ( P ＜ 0. 05), but no significant difference was found between stages and clinical grading of uterine cervix adenocarcinoma( P ＞ 0. 05). Conclusion The hyper expression of COX-2 mRNA in uterine cervix adenocarcinoma took part in the carcinogenesis of tumor.

ObjectiveTo explore the relation of the expression of intron 9 in CD44 gene,nm23 gene and the serum levels of TGFα and TNFα to the development, metastasis and prognosis of epithelial ovarian cancer. Methods The expressions of intron 9 in CD44 gene, nm23 gene, TGFα and TNFα in epithelial ovarian cancer were measured by semi -quantitative RT - PCR, immunohistochemical technique and radioimmunoassay ( RIA ). Results There was positive expression of intron 9 in CD44 gene,nm23 gene,TGFα and TNFα in 36 cases of epithelial ovarian cancer. The higher levels of nm23 gene and TGFa were obvious in early stage of ovarian cancer. ConclusionTo study the ovarian cancers biologic behavior with these multipe factors can provide theoretical basis for early diagnosis, gene therapy and predicting prognosis.

ObjectiveTo explore the effects of optional cesarean section on the level of plasma motilin and serum gastrin in umbilical blood and their relationship with gastroenteric symptoms of neonates. MethodsWe measured the concentrations of plasma motilin and serum gastrin in umbilical blood from neonates undergoing optional cesarean operation, emergency cesarean section and vaginal delivery by radioimmunoassay(RIA). ResultsFull-term deliveries undergoing optional cesarean section were with significant gastrointestinal symptoms. Plasma motilin and serum gastrin were significantly lower in neonates undergoing cesarean operation without birth initiate group(optional cesarean section)than that in cesarean section with birth initiate group and vaginal delivery group (P<0.05). ConclusionCesarean operation without birth initiate influences neonatal gastroenteric symptoms.Breast feeding which begins as early as possible will help to relieve those symptoms.

How to reduce immune response is an unprecedented challenge for rAAV gene medicine. Recent studies suggested that lowering dosage of the vector used could reduce immune response caused by rAAV gene medicine. Nevertheless, it would also decrease the transgene expression, leading to failure of gene treatment. It is therefore important to take appropriate steps to maintain high gene expression level and pharmacodynamic, while the dosage of rAAV used is reduced. Here, steps to enhancing gene therapy, such as optimization of the administration, reconstruction of the viral vector and selection of the promoter, are discussed in order to achieve maximum outcome.

Objective To evaluate the effect of sequential intrahepatic arterial FAM for the treatment of metastatic gastric cancer to the liver. Methods 14 patients with multiple hepatic metastases from gastric cancer were treated with sequential intrahepatic arterial FAM using the hepatic artery infusion port. Results Of 14 patients, CR, PR, NC and PD were observed in 1, 7, 4 and 2 cases respectively. The overall median survival was 15 months. The survival rate at 1, 2 and 3 years was 80.0%; 57.1% and 14.3% respectively. No severe complication was observed. Conclusions Sequential intrahepatic artery FAM is effective to increase the survival rate in patients with hepatic metastases from gastric cancer.

Objective To evaluate the efficacy of FAP combined intrahepatic artery with intravenous infusion chemotherapy in the treatment hepatic metastatic carcinoma. Methods 23 patients with metastatic hepatic carcinoma were diagnosed with CT or MRI. EPI 40mg/m 2, CDDP 60mg/m 2 were given intrahepcic arterial by means of one shot infusion and 5-FU 500mg/m2 (d1, d8) intravenously respectively. All patients were reexamined by with CT or MRI after 2～4 weeks. Results The total response rates was 74%. The survival rates at 1 year, 2 year and 3 year were 88 8%?7 9%;66 9%?12 3% and 24 6%?23 4% respectively. The median survival time was 25 months. Conclusions FAP was a traditional regimen,combined intrahepatic arterial and intravenous chemotherapy can improve response rate and prolong median survival to metastatic liver cancer .
