Objective To investigate the prevalence of renal insufficiency and its associated factors in type 2 diabetes mellitus with normoalbuminuria using estimated glomerular filtration rate ( eGFR) .Methods We retrospectively analyzed 10-year data of chronic complications in type 2 diabetics in-patient from the Chinese Diabetes Society.eGFR was estimated using the equation from Modification of Diet in Renal Disease(MDRD) study.The clinical characteristics as well as associated factors for low eGFR were analyzed among the normoalbuminuric type 2 diabetic patients.Results A total of 1351 type 2 diabetic patients were included, 755 patients with normoalbuminuria, 466 patients with microalbuminuria and 130 patients with macroalbuminuria respectively.Among the patients, 310 (22.9% ) had low eGFR (GFR <60 ml · min~(-1) · 1.73 m~(-2) ) , 19.7% (149/755) in the patients with normoalbuminuria, 21.9% (102/466) in microalbuminuria and 45.4% ( 59/130 ) in macroalbuminuria Patients with normoalbuminuria and low eGFR suffered more chronic complications than those with normoalbuminuria and normal eGFR, mainly retinopathy, cerebrovascular diseases and sensory neuropathy.Stepwise logistic regression analysis revealed that age ( OR = 1.042, P < 0.001), diabetic duration ( OR = 1.038, P = 0.045), systolic blood pressure (OR = 1.017, P < 0.001) were independently associated with renal impairment among the patients with normoalbuminuria.Body mass index ( OR = 0.868, P < 0.001) and HbAlc (OR =0.898, P =0.021) were also related with renal insufficiency.Conclusion A considerable proportion in type 2 diabetic patients without albuminuria may exist renal impairment, and eGFR estimation could benefit the evaluation of renal function in such patients.

BACKGROUND: The c-fos gene is commonly expressed in neurons,which may act as one of the signs of activities and reflection of injured neural cells.OBJECTIVE: To investigate the expression of hippocampal c-fos gene of rats with ischemic cerebral injury and the protective role of shenmai injection at the molecular level.DESIGN: Randomized controlled study.SETTING: Department of Histology and Embryology, Luzhou Medical College.MATERIALS: The experiment was completed at the Department of Histology and Embryology, Luzhou Medical College from January to March 2002. Totally 30 male Wistar rats were randomly divided into control group, ischemia group and treatment group with 10 in each group.METHODS: Bilateral common carotid arteries of rats in the ischemia and treatment groups were splinted for 30 minutes and reperfused for 1 hour to establish models of ischemic cerebral injury. Rats in the treatment group were injected with 2 mL/kg of shenmai (constituted with hongshen, dwarf lilyturf tuber and other Chinese herbal medicines) 30 minutes before ischemia. Rats in the ischemia group were not treated with any drugs, and rats in the control group were treated with sham operation but without splinting common carotid artery and giving any drugs. Hippocampal tissue of rats was obtained to make paraffin sections. In every group, one section from each rat was taken at random. Totally 100 neurons of every group were counted. Expression of c-fos gene in hippocampal neuron was observed according to the nuclear color of neurons (+++ as dark-brown mark;++ as brown mark; + as light brown mark; - as no brown mark).MAIN OUTCOME MEASURE: c-fos expression of hippocampal neurons of rats in each group.RESULTS: Totally 30 rats entered the final analysis. Expression of c-fos gene in hippocampal neurons was significantly more in the ischemia group than that in the control group (+++: 24/visions, 7/visions, P < 0.05); but that in the treatment group was less than that in the ischemia group (+++:13/visions, 24/visions, P < 0.05).CONCLUSION: Shenmai injection can reduce the expression of c-fos gene in hippocampal neurons of rats with ischemic cerebral injury, and can protect neural cells of ischemic cerebral injured tissue.

OBJECTIVETo promote development and utilization of Ophiocordyceps gracilis in xinjiang and provide basic data for researching and sustainable developing medicine fungus related to O. gracilis.
METHODA white strain SFYT002 isolated from the sclerotium of O. gracilis in Xinjiang was researched by morphological observation, ITS and 18SrDNA sequencing. The ITS and 18SrDNA sequences of the strain were determined, BLAST was compared with the other sequences of Tolypocladium in GenBank. The phylogenetic trees of ITS and 18SrDNA sequences were analyzed in Tolypocladium. In addition, the filter paper method was used to study the antibacterial effects.
RESULTThe main morphological characters of this strain were white cotton-like colonies, phialide with inflated base, drastically sharping with partially bending tips, small and transparent budding spores with being always assemble to spearhead and globular, subglobular or ellipse conidiospores. The phylogenetic trees of ITS and 18SrDNA sequences were constructed and analyzed in Tolypocladium. It was resulted that Tolypocladium was confirmed to be monophyletic, and the strain SFYT002 was the same as the systematic position of others of T. inflatum. Meanwhile, the antibacterial test was performed against the 4 common pathogenic bacteria. It was showed that both fermentation and its extracts of different polar from this strain possessed good anti-bacteria capacities.
CONCLUSIONThe strain SFYT02 was identified as T. inflatum, and inhibited effectively growth of bacteria.

Objective To investigate the therapeutic effects of fluorouracil implants in Stage Ⅲgastric carcinoma patients after radical gastreetomy. Methods The general state of health and cumulative survival of 200 stage Ⅲ gastric carcinoma patients undergone radical gastrectomy from January, 1999 to, December 2002 in the People's Hospital of Zhongshan City were analyzed, in which only 120 patients administrated fluorouracil implants during radical gastreetomy. The therapeutic effects of fluorouracil implants in stage Ⅲ gastric carcinoma patients after radical gastrectomy were observed. Results The differences of weight (P = 0.041), HGB(P =0.024), Plt(P =0.017), CEA(P =0.001), CA19-9(P =0.003) were significant between two groups. The incidence rate of nausea/emesis in group T (28 %) was higher than that in group O(17 %, P = 0.006), and incidence rates of myelosuppression(P =0.81), diarrhea(P =0.72), hepatic function lesion(P =0.97) and renal function lesion(P =0.20) were no significant. The cumulative 5-year survival rate of group T(45 %) was higher than that in group O (15 %, P =0.002). Conclusion Fluorouracil implants can improve the therapeutic effects on gastric carcinoma patients undergone radical gastrectomy.
