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.

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.

OBJECTIVE:To evaluate the utilization of traditional Chinese medicine(TCM) in our hospital and to provide reference for TCM pharmacy and rational use of TCM in the clinic.METHODS:1 052 outpatient prescriptions of TCM in our hospital from May to Oct.in 2009 were analyzed statistically by Microsoft Excel program.RESULTS:Prescriptions of respiratory system diseases in our hospital were mainly TCM prescription.TCM in middle-aged and aged group was a universal phenomenon.The ingredients in every prescription were excessive with high dosage.CONCLUSION:Clinicians and pharmacists should attach great importance on the application of TCM prescriptions to ensure safety and effectiveness of drug use.

Objective To study the pathologic and molecular genetic characteristics of Chinese patients with oculopharyngeal muscular dystrophy(OPMD).Methods The ultrastructural muscle biopsies in 6 patients were carried out by using transmission electron microscopy.The DNA was obtained through blood samples from patients(n=11) and the at-risk individuals(n=16).Amplification of the PABPN1 gene mutation region was performed by polymerase chain reaction(PCR).The sequences were obtained and compared with the genomic sequence of the human PABPN1 gene.Results Intranuclear inclusions(INIs) were found by electron microscopy in 4 patients,and the rate of appearance was 18%,20%,34% and 40%.Sequence analysis of exon 1 of PABPN1 gene showed abnormal expansions of the GCG-repeat—(GCG)_8 and(GCG)_(10) in 9 patients.Conclusions INIs might be found by electron microscopy in muscle biopsies of OPMD patients.The rate of appearance of INIs should have positive relationship with the amount of the GCG-repeat.PABPN1 gene mutations might be present among Chinese patients with OPMD,and should have a negative relationship with the age of onset.

OBJECTIVE: To study the clinical application of oral antihypertensive drugs in our hospital for the references of clinics on rational administration. METHODS: Statistical analysis on the application of oral antihypertensive drugs in our hospital from 2001 to 2004 was conducted in terms of the administration varieties, consumption sum, administration frequency, daily costs, etc. RESULTS: The yearly consumption sum of the oral antihypertensive drugs had been the highest among the cardiovascular drugs, with dihydropyridines and angiotensin-converting enzyme inhibitors dominating the first 2 places and with nifedipine retard tablets and amlodipine besylate tablets dominating the first 2 places in terms of the sequence of single variety. CONCLUSIONS: The application of oral antihypertensive drugs in our hospital is basically in line with the domestic and abroad general medication situation and corresponds to the current medication principle of antihypertensive drugs.
