Objective To examine the circulating glucose and body weight in the transgenic MKR mouse model who expressed dominant-negative IGF-1 receptor and insulin receptor in skeletal muscle leading to systemic insulin resistance and diabetes. Methods MKR mice were genotyped by PCR analysis of tail DNA.And in these mice we examined the circulating glucose and body weight once a week from 1 to 16 weeks of age, and the circulating insulin and glucose tolerance at age of two-month-old by using C57 mice as controls. Results The descendents of MKR mice kept hereditary feature. And these mice had hyperglycaemia from 3 weeks of age,and an increasing body weight slowly(P

Objective To investigate the effect of tuftsin and its inhibitor on pancreas microcirculation in acute pancreatitis(AP). Methods Sprague Dawley (SD) rats were randomly divided into five groups. Murine AP model was produced by retrograde injection of 4% sodium taurocholate into pancreatic duct, tuftsin or its inhibitor was injected at a dosage of 75 ?g/kg. At the time of 0,3, 6, 12 h, pancreas was harvested for pathology of microthrombus. esults Microthrombus in control group was not different with that in tuftsin group; At the time of 3、6 and 12 h microthrombus in other 3 groups significantly increased than control group and tuftsin group; With time, microthrombus in AP group、AP+ tuftsin group and AP+inhibitor group increased steadily and statistically significant; Tuftsin inhibitor significantly decreased microthrombus at the time of 6、12 h.Conclusions In acute pancreatitis tuftsin deteriorated pancreas microcirculation, which could be partially reversed by the administration of tuftsin inhibitor.

OBJECTIVETo explore the curative effect and safety of acupuncture for mild cognitive disorders after stroke.
METHODSRandomized controlled trial was adopted and one hundred cases conforming to criteria were divided into a combined acupuncture and medication group (group A) and a medication group (group B), 50 cases in each group. The basic treatment of cerebrovascular disease was applied in two groups. The group A treated was with acupuncture at Baihui (GV 20), Shenting (GV 24) and Qucha (BL 4) etc. and oral administration of Nimodipine. In group B, Nimodipine was taken orally. The treatment lasted for 3 months, the scores of Mini-Mental State Examination (MMSE), modified Hasegawa Dementia Scale (HDS-R) and Barthel Index (BI) were observed before and after treatment in two groups.
RESULTSThe total effective rate in group A was 66.7% (32/48), which was superior to 30.4% (14/46) in group B (P < 0.05). The scores of MMSE, HDS-R and BI after treatment were apparently improved as compared with those before treatment in two groups (all P < 0.01). The improvements in group A were superior to those in group B (all P < 0.05). There was no adverse event reported during the treatment in two groups.
CONCLUSIONAcupuncture can improve activity of daily living and has significant effect in treating mild cognition disorders after stroke without adverse reactions.

Objective To investigate the relationship between interleukin-17 (IL-17) and vitiligo.Methods Totally,32 vitiligo patients and 30 healthy human controls were enrolled in this study.Blood samples were collected from all the subjects,and enzyme-linked immunosorbent assay (ELISA) was performed to determine the plasma levels of IL-17.The relationship of plasma IL-17 levels with disease stage,clinical course and lesion area was assessed.Results The plasma levels of IL-17 were significantly higher in the patients with progressive and stable vitiligo than in the healthy controls (both P < 0.05),and higher in the patients with progressive vitiligo than in those with stable vitiligo (P < 0.05).Moreover,the plasma levels of IL-17 were positively correlated with the area of vitiligo lesions (r =0.456,P < 0.05),but unrelated to the clinical course of vitiligo (r =0.239,P > 0.05).Conclusion IL-17 may play a certain role in the occurrence and development of vitiligo.

Objective To construct a full-length cDNA library of human normal kidney tissues and identify the quality of the library. Methods By using the template-switching mechanism at 5′end of mRNA technique to construct the library, a powerscript reverse transcriptase was used to transcribe, and a 5′-oligo fragment as an extended template was added to 5′ end of mRNA to enrich full-length cDNAs. After amplification, the ds cDNAs digested by sfi I and size-fractionated by columns were recombined into ?TripIEx 2 vectors. After package, the recombinant vectors were titered and the recombinant rate (blue/white) was determined,then the library was amplified. We identified the library using PCR reaction to determine the size of the inserts. Results The titer of cDNA library was 2.6?10 6pfu?mL -1, the rate of recombinant was above 95%, and the titer of amplified library was 9?10 11pfu?mL -1. The insert size ranged from 0.7 to 2 kb. Conclusion The cDNA library of human normal kidne we constructed is a highly efficient one and can be used for screening by probe and antibody to find the genes related to kidney diseases.
