Objective:To investigate the relationship between TGF-? 1mRNA and acute rejection of small intestinal allografts in rats.Methods:Rats were divided into two groups.Group Ⅰ:Wistar→SD Small intestinal transplantation,Group Ⅱ:Wistar→SD Small intestinal transplantation+CsA.The pathologic changes of allografts at 3 rdday,5 thday,7 thday after operation investigated and the transcription of IL-2,IFN- ?,and TGF-? 1mRNA was detected by semi-quantity RT-PCR.Results:Pathologic change:There was acute rejection at 3 rdday,and became severe at 7 thday in group Ⅰ,and there was only slight rejection at 7 thday in groupⅡ.TIFN-?、IL-2mRNA obviously increased after operation in groupⅠ.But they increased only a little in group Ⅱ.It had statistical significance between the two groups(P

OBJECTIVETo observe the efficacy of combination therapy of clomiphene and Chinese drugs for nourishing Shen and activating blood circulation (NSABC) in treating Stein-Leventhal syndrome caused sterility.

METHODSSixty-two patients with anovulation caused sterility were randomly divided into the treated group (n = 32) and the control group (n = 30). The treated grop was treated with the combination therapy and the control group treated by the same dosage of clomiphene alone.

RESULTSAfter treatment, when comparing with that before treatment, the endocrine hormones in the treated group improved significantly, showing a markedly decrease of androgen and luteotropic hormone, and increase of estrogen (P < 0.001). The periodic ovulation rate in the treated group reached 87%, the total pregnancy rate being 65.6%, with no occurrence of ovarian hyperstimulation syndrome (OHSS) and luteinized unruptured follicle syndrome (LUFS), while in the control group, the periodic ovulation rate was 66%, the total pregnancy rate 36.6%, with LUFS occurred in 4 patients. Comparison of the therapeutic effects between the two groups showed significant difference (P < 0.05).

CONCLUSIONThe combination therapy of clomiphene and NSABC has a better therapeutic effect in treating Stein-Leventhal syndrome caused sterility than that of using clomiphene alone.

Objective To investigate clinical significance of computed tomography (CT) scan in diagnosis of bronchial foreign body in children.Methods Twenty-one suspected children with bronchial foreign body were studied with spiral CT cross-section scan and coronal reconstruction and diagnosis was confirmed with bronchoscopy.Results The foreign body was displayed in all of 21 cases. CT scan showed foreign body was located in right main bronchial 12 cases, right middle bronchial 1 case, right inferior lobar bronchial 2 cases and left main bronchial 6 cases. Foreign bodies were extracted with bronchoscopy.Conclusion CT scan can display and locate accurately foreign body in bronchial of children,and has very important diagnostic value in patients having atypical histories, clinical and radiological findings.

Objective In a new hospital,the construction of the ethics committee is also gradually evolving.This article aims to describe the current status of the ethics committee,analyze and summarize identified problems in the operation of the ethics committee,to propose a solution for better construction of ethics committee.At the same time,it can also provide certain reference for the new establishment of Ethics Committee of other institutions.Methods This paper analyzes the construction and current situation of operation of the ethics committee in detail.Results The ethics committee is running well,but there are still some problems such as management mode to be further optimized and ethical review system to be further strengthened.Conclusions The construction and capacity building of the EC is a continuing effort.On-going improvement of identified problems plays significant role in better construction of the ethics committee.

Sterilization operation, as the key operation unit that affects the quality of Chinese materia medica (CMM) and its preparations, directly affects the safety, effectiveness, quality, and stability of medicine. The classification, principle, application status, advantages, and existing problems and countermeasures of CMM and its preparations were systematically analyzed. There are many sterilization processes for CMM and its preparations, including dry heat sterilization, moist heat sterilization, radiation sterilization, epoxy ethane gas sterilization, and so on, but they all have many problems and greatly affect the quality of CMM and its preparations. A sterilization process should be chosen according to the nature of CMM and its preparations, which is suitable for the CMM or the dosage form, so as to accelerate the development and transformation of new sterilization technique of the CMM and its preparations.

OBJECTIVE To investigate the HIV infections states in tumor patients for clinical diagnosis,treatment and to prevent HIV infection in the tumor hospital.METHODS The result of HIV detection in tumor patients from Dec 2000 to Aug 2006 was analyzed by the review statistics analysis.RESULTS Totally 48 101 tumor paients were detected,and the number of tumor patients with positive HIV antibody result was 51(0.106%).Among the positive patients there were 21 cases with blood transfusion history,14 cases with blood donating experience,2 cases with both these two kinds of experiences and 14 cases without the two kinds of experiences.Their rate was separately 41.0%,27.5%,4.0% and 27.5%.Most of the HIV positive patients had no clinical synptoms.CONCLUSIONS The HIV positive rate of patients with blood transfusion or blood donating is significantly higher than the patients without these experiences.The routine detection for the HIV before the operation,blood transfusion or other traumatic detection is very necessary.

0.35 U?L-1 was taken as standard of positive detection.Among all the 20 allergen,atopy could be diagnosed by one positive allergen detected.The controlling non-atopy group were the controlls.Reverse transcription polymerase chain reaction assay was used to detect viruses in the nasopharyngeal secretions of these patients,including respiratory syncytial viruses,rhincvirus,influenza virus,parainfluenza,human metocpneumo virus,human bocavirus,enterovirus.The virus-positive patients were then divided into 2 groups,atopic virus-positive group and non-atopic virus-positive group.Cytokines IL-12 and IL-27 were further determined using enzyme-linked immunosorbent assay me-thod.Results A total of 65 cases(56.0%) and 77 cases(66.4%) out of 116 cases of recurrent wheezing children,were found to be allergen-positive and virus-positive,respectively.The virus-positive rate was 75.4% in atopic group and 54.9% in non-atopic group.There was a significant difference in the virus-positive rates between the atopic and non-atopic group(?2=5.37,P0.05).Furthermore,serum IL-12 and IL-27 in the atopic group were significantly higher than those in the non-atopic group(t=2.579,2.573,Pa

Objective To evaluate the efficacy of tibial bone-skin flap grafts in the management of se- vere traumatic osteomyelitis complicated with bone and skin defect in leg to avoid amputation.Methods From March 1998 to Aug.2004,12 cases of the traumatic osteomyelitis complicated with bone and skin defect in leg were treated with vascularized tibial bone-skin flap graft.The longest flap was 17cm,widethest 10cm, The longest bone flap was 12cm.They were followed up for 0.6 to 5 years.Results All the tibial bone-skin flaps survived completely,2 cases of osteomyelitis recurred.The followed-up,from 0.5 to five years,showed good bone union in all cases,averageing 15 weeks.The infection was under control.The leg function and con- tour were satisfactory.Conclusion The tibial bone-skin flap has the advantages of having distinguished sign of anatomy,highly vascularized,easy to obtain,simply and flexible procedure,improving circulation,short- ens hospitalization and suitable for treatment of traumatic osteomyelitis complicated with bone and skin defect in leg.
