BACKGROUND: The morbidity of diabetes mellitus increased recently.There are few reports about the pulmonary function status of the patients with diabetes mellitus.OBJECTIVE: To comparably observe the difference of the pulmonary function status between patients with diabetes mellitus and normal persons,and to probe into the relationship between the course of disease of diabetes mellitus and the functional change of pulmonary function.DESIGN: Case controlled observation SETTING: Renmin Hospital, Wuhan University PARTICIPANTS: Totally 90 patients with diabetes mellitus hospitalized in the Renmin Hospital, Wuhan University between January 2000 and De cember 2003 were recruited. All the patients participated in the experiment voluntarily. Totally 20 cases were of insulin dependent diabetes mellitns (IDDM) and 70 cases were of non-insulin dependent diabetes mellitus (NIDDM). Another 90 cases were divided into 2 groups with the boundary line of 10 years: group with disease course ＜10 years (n=40) and group with disease course ＞10 years (n=50). And 30 normal persons with healthy pulmonary function was set as healthy control group, all the testees were voluntary participants in the experiment.METHODS: Pulmonary function index of the participants of each group was measured: vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1%), peak expiratory flow rate(PEFR)maximal voluntary ventilation (MVV) and comparison was performed between them.Comparison of the pulmonary function status of the patients between different levels of diabetes mellitus.pulmonary function between different groups : Compared with health control group, VC , FVC and MVV of the patients with diabetes mellitus was significantly decreased (t=1.999-2.301, P ＜ 0.05).There was no significant difference in the VC, FVC and MVV between patients with monary function between patients with different diabetes mellitus: the pulmonary function status in the group with disease course ＞10 years was improved less than that in the group with disease course ＜10 years [ VC (L):2.62±0.65 vs 3.25±1.25;FVC(L): 2.40±0.52 vs 3.21±0.98;FEV1%:75.31±2.31 vs 80.63±5.56;PEFR (L/s):4.33±0.68 vs 5.98±1.02;MVV (L/s): 76.22±6.98 vs 89.21±5.69 (t=2.012-2.350, P ＜ 0.05)].CONCLUSION: Pulmonary function of the patients with diabetes mellitus has reduced tendency compared with the normal persons, and the pulmonary function of the patients with long course of disease decreases significantly. More attention should be paid to diabetes patients' pulmonary function changes.

OBJECTIVE:To study the protective effect of Compound pueraria tablets on the aging model rats. METHODS:The rats were divided into normal group,model control group,positive control group (vitamin E) and Compond pueraria tablets high-dose,medium-dose and low-dose (800,400,200 mg/kg) groups. The aging model rats were made by injection of D-galac-tose solution for 30 d in latter 5 groups,and they were given relevant medicine at same time every 7 days for consecutive 56 days since 31st day. SOD activity and MDA content in the serum and myocardium and LPF contents in the myocardium were determined after the last dosing,and apoptotic cells were counted and the pathology of cerebral tissues were observed. RESULTS:Compared with normal group,the activity of SOD in the serum and myocardium were decreased significantly in model control group,MDA and LPF contents in the myocardium and the number of apoptotic cells were increased significantly(P<0.01);significant myocar-dial cell injury was found. Compared with model control group,the activity of SOD in the serum and myocardium were increased significantly,while MDA and LPF content in the myocardium and the number of apoptotic cells in Compound pueraria tablets high-dose,medium-dose and low-dose groups were decreased significantly(P<0.05 or P<0.01);myocardial cell morphology was improved significantly. CONCLUSIONS:Compound pueraria tablets has obvious protective effect on myocardial cells in aging rats induced by D-galactose,the mechanism maybe related to the increase of SOD activity and the decrease of the content of MDA and LPF.

Objective To analyze the effect of overweight on appendicitis and laparoscopic surgery.Methods Clinical data of 200 patients with laparoscopic appendectomy were analyzed retrospectively.Overweight and non-overweight patients were compared.The risk factors of appendicitis were analyzed.Results The operation time [(56.19 ± 30.42) min vs.(48.40 ± 21.03) min] and length of stay [(5.35 ± 2.04) d vs.(4.52 ± 1.49) d] between the overweight and non-overweight groups had statistically significant differences (t =2.040,P =0.043,t =3.219,P =0.002).Overweight was correlated with appendix inflammation (OR =0.149,P =0.000).Conclusion Over weight patients are prone to develope into complicated appendicitis.It should take surgeon's attention for more difficult operation and more complication.

Neurolymphomatosis(NL) is characterized by lymphomatous infiltration of the peripheral nervous system. We report a case of neurolymphomatosis(NL) which was confirmed by sural nerve biopsy. Sural nerve specimen from a 49-year-old female patient with weakness of limbs was examined with routine histochemical and immunohistochemistry staining, in which the first antibodies against CD3, CD20, CD45, CD45RO and CD68 were used. Numerous T-lymphoma cells invaded in the adipose tissue of epineurium of sural nerve. The nerve biopsy showed marked axonal degeneration of myelinated fibers. The clinical and histopathologic findings confirmed the diagnosis of neurolymphomatosis.

Objective To construct prokaryotic recombinant plasmids of transcriptional co-activator (TC) gene of Clonorchis sinensis, express and purify the recombinant protein and analyze its biological function. Methods A pair of primers was designed according to the known sequence of TC gene. The TC gene fragment was amplified by PCR. After purification and digestion with BamHⅠ and SalⅠ , the TC gene was connected to the prokaryotic expression vectors, pGEX-4T-1 and pET30a(+). By cloning target gene into these vectors, pGEX-4T-1 and pET30a(+), prokaryotic recombinant plasmids of TC gene were constructed and transferred into E.coli BL21. The positive expressed recombinants were detected by SDS-PAGE and Western blotting. Immobilized metal (Ni 2+ ) chelation affinity chromatography was used to purify His-TC produced by the expression of the recombinant protein pET30a(+)-TC. Results The recombinant plasmids, pGEX-4T-1-TC and pET30a(+)-TC, were constructed successfully. SDS-PAGE testified that the molecular weight of the recombinant protein was correct. Western blot analysis of GST-TC recombinant protein testified that the recombinant protein could be recognized by immunized rabbit serum, which means the protein is GST-immune active and the clone can express recombinant Clonorchis sinensis antigen. After affinity chromatography of the pET-TC protein, there was only one protein band with expected size on the SDS-PAGE gel. Conclusion The TC gene was screened from cDNA library of adult Clonorchis sinensis, cloned, expressed and purified. The purified protein of TC gene will be of importance for further research on the biological function of the gene.

OBJECTIVE:To study the effects Weide'an tablet on gastric function and the expressions of epidermal growth fac-tor(EGF)and its receptor(EGFR)in gastric tissue of model rats with stress-induced gastric injury,and investigate its mechanism in the treatment of gastric ulcer. METHODS:Rats were randomly divided into normal group (normal saline),model group (nor-mal saline),positive group (ranitidine hydrochloride,0.015 mg/kg) and Weide'an tablet high-dose,medium-dose,low-dose groups (1.7,0.87,0.43 g/kg),10 in each group. Except for normal group,rats in other groups were given fasting swimming in cold water to induce gastric ulcer model. After modeling,all rats were intragastrically administrated once a day,for 2 weeks. The body mass of rats in 0,7,14 d of administration was recorded. After 12 h of last administration,gastric juice secretion,gastric juice pH,gastric ulcer area and gastric mucosal damage index of rats were detected,and the expressions of EGF and EGFR in gas-tric tissue were detected. RESULTS:Compared with normal group,body mass and gastric juice pH in 7,14 d in model group were declined;gastric juice secretion and gastric ulcer area were increased,gastric mucosal damage index was increased;and the expressions of EGF and EGFR in gastric tissue were enhanced,with statistical significances(P<0.05 or P<0.01). Compared with model group,except that the body mass,gastric juice secretion,gastric juice pH and gastric ulcer area in Weide'an medium-dose group in 7 d,and body mass,gastric juice secretion,gastric juice pH,gastric ulcer area and the expression of EGF in gastric tis-sue in Weide'an low-dose group in 7,14 d were not significantly improved,above indexes were significantly improved in other ad-ministration groups(P<0.05 or P<0.01);and the effect of Weide'an tablet showed a certain dose-effect relationship. CONCLU-SIONS:Weide'an tablet can significantly improve the gastric function of model rats with stress-induced gastric injury;and the mechanism may be related with enhancing the expressions of EGF and EGFR and promoting ulcer healing.
