Celiac disease (CD) is a chronic autoimmune gastrointestinal disorder induced by ingestion of gluten-containing foods.In the past CD was thought prevalent only in Western countries,whereas it has been found common throughout the world and increasing numbers of Chinese patients has been reported recently.However,there are still many deficiencies in management of patients with CD in China and either the diagnosis or the treatment of CD is lacking evidence-based clinical pathway.We report a case of a young woman with CD presenting with chronic diarrhea,abdominal distention,and weight loss,whose outcome was improved by following evidence-based guidelines of medical nutrition therapy.Diagnosis and treatment of the patient was analyzed with review of foreign and domestic literature to provide readers reference of the standardized nutritional intervention of CD.

Objective To explore whether living in rural areas may reduce the risk of atopic sensitization. Methods The standardized questionnaires were answered by the parents of 2 986 school children during 2004 to 2005. Radioallergosorbent technique-fluorescence enzyme immunoassay (RAST-FEIA) was used to determine the level of specific IgE in the serum of the children. The risk factors were analyzed by Logistic regression. Results Compared with the subjects living in the towns from birth, the risk of atopic sensitization was lowest in the subjects living in the villages from birth (OR=0.32, 95%CI: 0.11-0.62) and it was moderate in the subjects who had relocated from village to town (OR=0.51, 95%CI: 0.28-0.92), there was a significant trend among them (P for trend

Objective:Toprepare poly-DL-lactide-poly (PELA) microspheres encapsulating recombinant tissue inhibitors of metalloproteinase-1 (TIMP-1) adenovirus, and to investigate their effects on the proliferation of hepatocellular carcinoma HepG2 cells. Methods: The microsphere was constructed by encapsulating recombinant adenovirus containing TIMP-1 in biodegradable PELA. The diameter of the microsphere, quantity of virus encapsulated, loading rate, and releasing kinetics were measured. HepG2 cells were infected with the microspheres; the infection efficiency was examined by fluorescent microscope; and the ultrastructure was observed by TEM. The expression of TIMP-1 mRNA in HepG2 cells was examined by semi-quantitative RT-PCR, and the proliferation of HepG2 cells was detected by MTT assay. Results: The microsphere encapsulating recombinant TIMP-1 adenovirus was successfully constructed, with its diameter, entrapment efficiency, and virus loading rate being 1.965, 60.0%, and 10.5×10~8/mg, respectively. About 60% of the viruses were released within 120 h, and the total releasing time was longer than 240 h. Infection with rAdTIMP-1 PELA microsphere efficiently induced TIMP-1 expression in HepG2 cells, and significantly inhibited the proliferation of HepG2 cells, with the inhibitory rate being 47%. Conclusion: PELA microsphere encapsulating recombinant TIMP-1 adenovirus can markedly inhibit the proliferation of HepG2 cells, which provides an experimental basis for the combining macromolecular chemistry and gene therapy for treatment of hepatocellular carcinoma.

Objective To evaluate the safety and feasibility of natural orifice transluminal endoscopic surgery(NOTES)with current available techniques and endoscopic accessories.Methods Transgastric and transvaginal endoscopic abdominal cavity exploration were performed in 6 female pigs.A needle-knife and a ERCP scalpel were used to make an anterior gastric wall incision,and a dilating balloon to expand the passage,through which a therapeutic gastroscope was sent into the abdominal cavity to seek the target organ.Partial liver resection was performed in 2 cases.For incision closure,a clip was applied to the incision orifice or it was just given putting-aside therapy.One week later,the abdominal cavity was examined via vagina.Another week later,it was observed via other incision of the stomach.Four weeks after the operation,the pigs were sacrificed.Adhesion,injury to the organs and closure of the incision were evaluated.Results Transgastric procedures were performed 12 times and transvaginal procedures 6 times.Mean operation time via stomach was 33.4±10.9 min.and that via vagina WaS 10.1±2.5 min.All animals recovered and gained weight after the operation.The incision healed up with no obvious complications.Re-exploration showed adhesion of various degrees,no effusion,or injury to the organs were observed.Ketamine plus propofol achieved satisfactory anesthetic effect with no complications.One of the two animals which underwent liver partial resection died of disphragmatic muscle perforation.Hemarrhage occurred twice,both in the procedures via satisfied.One case developed abdominal abscess.Conclusion It Was feasible and safe to perform NOTES via transgastric and transvaginal approach to the abdominal cavity and liver resection.But development of NOTES specific instruments is essential to the procedure.

ObjectiveTo investigate the treatment effects of comprehensive nursing intervention on patients with chronic obstructive pulmonary disease(COPD) treated by non-invasive mechanical ventilation with BiPAP mode.Methods96 patients with diagnosed COPD and using non-invasive mechanical ven- tilation with BiPAP mode were randomly divided into the control group(46 cases) which was treated with routine measures and the comprehensive nursing intervention group (50 cases) which adopted comprehen- sive nursing intervention according to experimental design. The frightening degree, incidence rate of com- plications and clinical treatment effect by ventilator were compared between the two groups.ResultsPa- tients compliance with treatment and clinical treatment effect by ventilator in the comprehensive nursing in- tervention group was better than that of the control group. The frightening degree and incidence rate ofcomplications were lower than those of the control group (P < 0.01 ).ConclusionsComprehensive nurs-ing intervention with non-invasive mechanical ventilation with BiPAP mode can improve the treatmentcompliance of COPD patients,reduce complications followed by non-invasive mechanical ventilation andreach the prospective treatment effect.

Objective To investigate the dynamic changes of plasma myoglobin(Mb),troponinⅠ(TnⅠ) and brain natriuretic peptide(BNP)levels in the course of acute myocardial infrction(AMI)and to detect the best marker for early diagnosis and outcome prediction.Methods Plasma Mb,TnⅠand BNP levels were measured in 49 patients with AMI both before and after thrombolysis therapy and 32 controls.Results Plasma levels of all the three markers were significantly higher in the AMI patients than those in the controls(P

Objective To observe the effect of intra-articular injection of dehydroepiandrosterone (DHEA)on the experimental osteoarthritis in rabbits and study the mechanism.Methods Forty rabbits un derwent unilateral anterior cruciate ligament transection(ACLT)and then divided into two groups randomly. 100?mol/L DHEA resolved in the dimethylsulphoxide were injected into the knees of experimental rabbits 4 weeks after transection,once a week for five weeks.Rabbits in the control group were treated under the same schedule using dimethylsulphoxide.All rabbits were killed 9 weeks after ACLT and the knee joints were evalu- ated by gross morphology and histology.The mRNA expression of metalloproteinases-3(MMP-3),tissue in- hibitor of metalloproteinases-1(TIMP-1)and interleukin-lbeta(IL-1?)in the cartilage and synovium was analyzed using reverse transcription polymerase chain reaction(RT-PCR).Results Gross morphologic in- spection and histological evaluation showed that the extent and grade of cartilage and synovium damage in the experimental group were less severe than the control group.The mRNA expression of MMP-3 in cartilage and synovium decreased significantly in the experimental group(both P＜0.05).The mRNA expression of TIMP-1 in cartilage and synovium increased significantly in the experimental group compared with that in the control group(both P＜0.05).No significant difference of IL-1?mRNA expression in cartilage was found between the experimental and the control groups(P＞0.05).The mRNA expression of IL-1?in the synovium was signifi- cantly suppressed in the experimental group compared with that in the control group(P＜0.01).Conclusion DHEA protects against cartilage degradation,alleviates synovium inflammation and inhibits the progression of osteoarthritis in the experimental model.Down-regulation of MMP-3 and up-regulation of TIMP-1 in cartilage and synovium and IL-1?in the synovium may be the mechanism of the protective effect of DHEA on os- teoarthritis.
