Objective To assess the efficacy and prognosis of a combination of endoscopic varices ligation(EVL) and Hassab procedure in patients with portal hypertension by miniature ultrasonic probe. Methods Twenty-three patients with esophageal varices received a combination of EVL and Hassab procedure for variceal eradication. The esophagus vascular structures were examined with endoscopy and miniature ultrasonic probe. Change of vascular structure was evaluated,recurrence and rebleeding of esophageal varices were investigated.Results After treatment,the esophageal varices were obliterated and collateral veins were diminished in size or obliterated. During a short-term follow-up,the recurrence and rebleeding rate of esophageal varices were 5.0 % and 0,respectively.Conclusions The combination of EVL and Hassab procedure can effectively shut off the portoazygous shunt,prevent esophageal varices bleeding. It is a simple and less cost procedure. The miniature ultrasonic probe plays a more important role in evaluating the treatments of esophageal varices.

Objective To evaluate the efficacy and safety of desloratadine citrate disodium versus epinastine for the treatment of chronic urticaria (CU).Methods A randomized,double-blind,double-dummy controlled clinical trial was conducted.Patients with CU were divided into test group and control group to be treated by oral desloratadine citrate disodium (8.8 mg/d) and epinastine (10 mg/d) respectively once a day for 28 days.All the patients were followed up after starting treatment.Therapeutic effect was evaluated,and adverse reactions were observed.Results One hundred and fifty-seven patients were enrolled in this study,and 142 patients were valid for evaluation of efficacy and safety at the end of study.After treatment for 28 days,there was no significant difference between the test group and control group in response rate (81.16 ％ vs.78.08 ％,P ＞ 0.05) or incidence rate of adverse reactions (13.89 ％ vs.12.16 ％,P＞ 0.05).Conclusion Desloratadine citrate disodium is effective and safe for the treatment of CU.

OBJECTIVE: By summary and analysis of rigid internal fixation for the treatment of maxillofacial fractures incision and exposure, investigate the plate reasonable surgical approach of fracture reduction and fixation titanium. METHOD: Summary of the 76 surgical cases, Counting the statistics of the number that the surgery ways choose by facial incision and fractures location, analysis of the indications for surgery and the advantages and disadvantages of various surgical approaches. Followed up for more than six months, in order to observe the recovery of occlusal function and the facial cosmetic results. RESULT: The upper jaw or cheek bone has the more possibility in facial fracture, which used of a small incision hidden under the lip gingival sulcus and lower eyelid. After six months, the facial wound healing recover in good occlusal with no obvious scarring. CONCLUSION Reasonable choice of surgical incision can make the fracture site exposure and the facial aesthetic effect into account.

OBJECTIVE: To analyze the current situation and developing trend of drugs used in hospitals of Guangdong Province .METHODS: The data of drugs purchased by 40 hospitals in Guangdong in the years 1999- 2001 was collected and analysed.RESULTS: The drug expenses increased year by year in years 1999- 2001.CONCLUSION: The sum of money of drugs consumed will increase year by year,however,the growth rate may decrease.The proportion of consumption of imported drugs will continuously decrease.

OBJECTIVE:To compare the costs and effectiveness of4treatment regimens for hypertension.METHODS:212cases of hypertension were randomly divided into4groups,group A treated with amlodipine,group B treated with fosino?pril,group C treated with candesartan cilexetil,and group D treated with losartan;the curative effects in each group were ob?served and cost-effectiveness analyses were made.RESULTS:The effective rate in group C was markedly higher than those in other3groups(P

Aim To investigate the effects of triptolide on the proliferation and apoptosis of cell line A549 in human Lung Adenocarcinoma. Methods MTT, DNA fragmentation assay, fluorescence stain and flow cytometric analysis were carried out.Results Triptolide notably reduced the survival rate of A549 cells, and inhibited the proliferation of A549 cells. The 50 % inhibitory concentration (IC50) for 72 h was 75 nmol?L-1 and it arrested the cell cycle at S phase at the concentration of 14 nmol?L-1 (P

Objective To investigate the differential diagnosis of Reye syndrome and the characteristics of primary carnitine deficiency,and to provide diagnostic strategy for similar cases.Methods There was a case presented with fever,poor response,convulsions and hepatomegaly hospitalized in Wuhan Children's Hospital,and the clinical manifestations were described,the physical examination was comprehensively conducted,the auxiliary examination results were recorded,some pediatric specialists from ICU,neurology department,genetic metabolic department,digestive system department were invited to discuss the case.The treatment was adjusted according to the suggested opinions;the treatment effects and the final diagnosis were tracked.Results The primary diagnosis of the case was central nervous system infection or toxic encephalopathy at the time of admission,but Reye syndrome could not be excluded.Although the cerebrospinal fluid test and brain MRI examination detected nothing abnormal,liver function suggested alanine aminotrans ferase ALT increase,blood sugar decrease,the liver volume increase,which was detected by liver ultrasound.Blood amino acids examination revealed the carnitine level decreased,and it was confirmed as primary carnitine deficiency in the end.L-carnitine was used to treat the disease,and its effect was good.Conclusions Great importance should be attached to children with onset age,physical check-up,and multidisciplinary cooperation.Use monism to explain the illness and the auxiliary inspection as far as possible,so that it can get early diagnosis and treatment,and the outcome is good.

AIM: To make comparative study on HPLC fingerprints of several kinds of Radix astragali from different sources. METHODS: ODS column was used,with mixture of acetonitrile and water as mobile phase in a gradient mode.The flow rate was 1.0 mL?min~(-1).The wavelength of measurement was at 203 nm. RESULTS: The fingerprints of Radix astragali were obtained. CONCLUSION: This method can be used to identify Radix astragali from different sources conveniently.

OBJECTIVE To evaluate application of cefoxitin disk diffusion method in detecting meticillin-resistant staphylococci(MRS)mediated by mecA gene.METHODS The cefoxitin disk diffusion method,oxacillin disk(diffusion) method,oxacillin agar dilution test,VITEK automicroscan as well as PCR amplification were performed and compared simultaneously for detection of MRS,and VITEK automicroscan was used in testing MIC.(RESULTS)(Among) 96 strains of Staphylococcus(16 S.aureus and 80 coagulase-negative staphylococci strains),54 strains of MRS(2 S.aureus and 52 coagulase-negative staphylococci strains) were identified by oxacillin disk(diffusion) method,oxacillin agar dilution test and VITEK automicroscan,48 mecA-genes were identified by PCR amplification(2 S.aureus and 46 coagulase-negative staphylococci strains) which was the same as by cefoxitin disk diffusion method.CONCLUSIONS The(cefoxitin) disk diffusion method is highly consistent with mecA gene method,and a reliable one of screening and(identifying) MRS mediated by mecA gene.

Purpose To construct expression vector of Fas extracellular region gene(eFas) ,to express and purify recombination protein and to prepare polyclonal antibody, which have laid a foundation of studying its function. Methods The eFas gene encoding sequence was acquired through overlapping PCR, and pET-22b ( + )/eFas expression vector was constructed. Then this vector was transformed into E. coli Rosetta-gami. Re-combinant protein was expression being induced by IPTG,and was purified using Ni-NTA matrix of affinity chromatograph. The purity of recombination protein was identified by SDS-PAGE. Hereafter, the purified eFas recombinant protein was immunized to New Zealand white rabbit in order to prepare polyclonal antibody. The titer of polyclonal antibody was determined by ELISA. Results The encoding sequence and expression vector of eFas was obtained while the interest protein was mainly expressed in the inclusion body. The eFas fusion protein's expression quantity accounts for more than 30% proportion of total E. coli protein. The eFas protein we obtained was provided with the purity of at least 95 % . Conclusion The successful constrution, expression and purification of FasL fusion protein and preparation of polyclonal antibody will provide some material for further studies of Fas.
