Objective To estimate the influence of abnormal glucose metabolism during pregnancy and family history of cardio-cerebrovascular disease and/or diabetes on umbilical C-peptide concentrations. Methods Chesed 85 pregnant women who had prenatal examination and their newborns as the subjects. Thirty-six newborns of mothers with gestational diabetes mellitus, impaired glucose tolerance or diabetes mellitus with pregnancy and 49 newborns of mothers with normal glucose tolerance were randomly chosed as the control group. All newborns were also classified according to whether their maternal grandparents had history of diabetes and/or cardio-cerebrovaacular disease. Therefore, there were four groups in this study: 25 newborns in group A were of diabetic mothers and positive family history, 11 newborns in group B were of diabetic mothers but negative family history, 9 newborns in group C were of mothers with normal glucose tolerance but positive family history, 40 newborns in group D were of mothers with normal glucose tolerance and negative family history. The blood samples of umbilical veins were collected at the time of delivery. Umbilical C-peptide levels of the four groups were measured by radioimmunonssay. Results The umbilical C-peptide concentrations of newborns in group A, B, C, D were (2.22±1.52), (1.44±0.63), (1.13± 0.34), (1.31±0.69) μg/L respectively, the umbilical C-peptide concentrations of newborns in group A were elevated compared to those of other three groups (F=5.11, P=0.003), and there were no significant differences in C-peptide levels of newborns between the three groups (group B vs C P=0.499, group B vs D P=0.694, group C vs D P=0.642). Conclusion Special attention should be given to newborns of diabetic mothers and whose maternal grandparents have history of diabetes and/or cardio-cerebrovascular disease.

Objective To investigate the psychological characteristics of the patients with functional dyspep-sia(FD). Methods The Zung serf-rating anxiety scale(SAS) and the Zung serf-rating depression scale(SDS) were employed to evaluate the anxiety mood and depression mood respectively of 110 FD patients ( group A) and 100 healthy volunteers (group B). The incidences of anxiety and depression in patients < 60 years and patients ≥60 years in group A were determined respectively. Results The anxiety ( 50.2±10.5 ) and depression scores ( 51.8±10.8)of group A were higher than group B [ (33.6±5.7) , ( 42.9±9.6) ] with a significant difference ( P<0.01 ). In group A, the anxiety incidence(66.0% ) in patients < 60 years was higher than patients ≥ 60 years (38.3%) ,while the de-pression incidence in patients ≥60 years(61.7% ) was higher than patients <60 years(42.0% ) ,both with signifi-cant differences ( all P<0.05 ). Conclusion FD patients show the psychological characteristics of anxiety and de-pression, and the characteristics type may vary in different age groups.

Diabetic foot amputation rate( Wanger 4,5 grade) of CN group and NU group was 44. 44%(4/9),6. 90%(2/29) respectively,the difference was significant(χ2=4. 732,P=0. 020). Conclusion The characteristics of high?risk groups of diabetics Charcot foot in the people with diabetic foot neuropathic ulcerations are middle aged,no foot of ischemia,combine the diabetic autonomic neuropathy and the feet always with recurrent ulcers.

Objective The experiment aims at probing the best condition of the isolation and purification of rat islets. Methods The islets were isolated from rat pancreas by hepatopancreatic duct perfusing with collagenase and purified with Ficoll 400 discontinuous density gradient centrifugation.Then the purified islets were subjected to histological staining,electron microscopy and radioimmunoassay for identification of specificity and viability. Results The histological staining revealed that the viability and the purity of the purified islets were above 95% and 85% respectively.Electron microscopy showed that the purified islets were morphologically intact with clear membrane and plenty of secreting granules.Radioimmunoassay demonstrated the secreted insulin concerntration between low-glucose groups and high-glucose groups varied significantly,which verified the good function of the islets.Conclusion Hepatopancreatic duct perfusing with collagenase is a good method for digestion.There are many factors that influence the quantity and quality of the acquired islets,such as the completed expansion of pancreas,the concentration and viability of collagenase and the digested time,etc.

Objective To explore the effect of activities of daily living (ADL) training on hemiplegia after stroke. Methods 50 stroke patients with hemiplegia were divided into treatment group (n=27), who received ADL training and physical therapy, and control group (n= 23), who only received physical therapy. They were evaluated with modified Barthel index (MBI) and the Brunnstrom classification. Results After 6 months of treatment, the score of MBI improved more in the treatment group than in the control group (P<0.05), but there was no significant difference in Brunnstrom stage (P>0.05). Conclusion ADL training can improve the recovery of ADL in hemiplegics after stroke.。

273 chinese have been studied with high voltage electrophoresis and immumofixation to survey the polymorphism of the third component of human complement in Shaanxi Provice Two C_3 phenotypes were found in this population, they are C_3SS and C_3FS The frequencies of C_3SS and C_3FS are 98.53% and 1.47% respectively. The frequency of C_3S gene is 0.9926 and C_3F gene 0.0073. These results are similar to other studies in China and this group was in Hardy-Weinberg equilibrium. Compared with Negro and Caucasian, the chinese population in Shaanxi Province has a significant difference in C_3 polymorphism.

AIM: To investigate the role of hydrogen sulfide (H_2S) in the cholecystokinin octapeptide (CCK-8) attenuating lipopolysaccharide (LPS)-induced lung injury. METHODS: A rat model of lung injury induced by intravenous injection of LPS was developed. Male Wistar rats were divided into normal control group, LPS group, LPS+CCK-8 group and CCK-8 group. Six hours after LPS injection, partial pressure of oxygen in the arterial blood (PaO_2), H_2S content and cystathionine-γ-lyase (CSE) activity in lung tissue were detected. The mRNA expression of CSE in lung tissue was determined by RT-PCR;the structure of lung tissues was observed under optical microscope. RESULTS: Compared to normal control rats, the LPS-treated rats had significantly decreased PaO_2 level, increased index of quantitative assessment (IQA) score, while H_2S content, CSE activity and the mRNA expression of CSE in lung tissue were significantly increased (all P<0.05). Administration of CCK-8 into LPS-treated rats increased the PaO_2 level and alleviated the degree of lung injury (measured by IQA score). In addition, CCK-8 decreased H_2S content, CSE activity, and the mRNA expression of CSE (all P<0.05). No significant difference of the above-mentioned parameters between CCK-8 group and normal control group was observed. CONCLUSION: CCK-8 reduces LPS-induced lung injury through inhibiting the generation of endogenous H_2S.

Objective To investigate the relationship between the pathophysiology of Helicobacter pylori induced antral gastritis and the expression of human β -defensin (HBD) -2 in peptic ulcer before and after Helicobacter pylori eradication.Methods Patients in peptic ulcer with Helicobacter pylori-posilive (23 cases) or Helicobacter pylori-negative (20 cases) were included.And 30 normal individuals were as controls.Biopsied gastric mucosa specimens from Helicobacter pylori-positive or Helicobacter pylori-negative individuals were done and normal controls were used.The specimens were examined for pathophysiology diagnosis and HBD-2 expression by immunohistochemistry before and after Helicobacter pylori eradication.Results Helicobacter pylori infection was correlated with the histological severities of both inflammation activity and atrophy in antral gastritis (r =0.574,0.640,P ＜ 0.01 ).The expression of HBD-2 was positively correlated with Helicobacter pylori infection in all the specimens (r =0.533,0.577,P ＜ 0.01 ).Immunohistochemistry using anti-HBD-2 antiserum revealed that HBD-2 expression and inflammation activity had significantly decreased in gastric specimens obtained after Helicobacter pylori eradication(P ＜ 0.01 ).The expression of HBD-2 had no variance in the case failing in Helicobacter pylori eradication (P ＞0.05).Conclusions Helicobacter pylori infection induces HBD-2 expression in the human gastric epithelium.HBD-2 inhibits the growth of Helicobacter pylori in vitro,which suggests that HBD-2 plays an antibacterial or inhibition role in Helicobacter pylori induced gastritis.In other words,the absence of HBD-2 should enhance the histological inflammation of Helicobacter pylori induced antral gastritis.
