Objective To investigate the clinical significance of combined detection of serum sTWEAK and cystatin C in early di‐abetic nephropathy (DN) .Methods 35 patients with DN(DN group) ,56 patients with diabetes mellitus (DM ,DM group) and 40 healthy cases conducted physical examination (healthy control group) were selected and serum levels of sTWEAK and cystatin C were detected .And levels of glycosylated hemoglobin(HbA1c) and qualitative urine protein test were conducted in DM group .Re‐sults The serum sTWEAK level in DN group was lower than that in DM group ,and the serum cystatin C level was higher than that in DM group(P<0 .05) .The serum levels of sTWEAK in DM group and DM patients with negative qualitative urine protein were lower than that in healthy control group ,while the serum cystatin C levels were higher than that of control group (P<0 .05) . Compared with DM patients with HbA1C< 10% ,the serum cystatin C level was higher and serum sTWEAK level was lower of those with HbA1c>10% (P<0 .05) .Conclusion The combined detection of serum sTWEAK and cystatin C could be a sensitive index for early diagnosis of DN ,with important significance in the occurrence and development of DN .

Objective:To investigate the effect of short-term intensive treatment with insulin on metabolic control,?-cell function and insulin resistance in newly diagnosed type 2 diabetic patients. Methods:Thirty-eight newly diagnosed type 2 diabetic patients were randomly divided into two groups and treated with continuous subcutaneous insulin infusion(CSII) or multiple daily insulin injection(MDI) for 1 month.Fasting blood glucose(FBG) and lipid profiles were measured,and oral glucose tolerance test(OGTT)was performed before and after the treatment.The second phase insulin and C peptide secretions were measured by calculating area under curve(AUC) in OGTT.HOMA model was used to evaluate ?-cell function((HOMA-?)) and insulin resistance. Results:Excellent control of FBG was achieved after 1 month intensive treatment.(HOMA-?) was improved significantly. Conclusion:The excellent metabolic control and ?-cell function improvement can be achieved by short-term intensive insulin therapies like CSII or MDI.

Objective To investigate the antimicrobial resistance of clinical isolates from a hospital in Chongqing during one year according to CHINET project.Methods Disc diffusion test (K-B method) was employed to study the antimicrobial resistance. WHONET5 was used for data analysis.Results In one year period from 2004 to 2005,690 non-duplicate isolates were collect- ed.Enterobacter isolates showed the lowest resistance rate to imipenem and meropenem.About 37.5% of E.coli and 31.4% of K.pneumoniae isolates produced ESBLs,respectively.All ESBLs-producing strains were susceptible to imipenem and mer- openem.About 37.2%,39.4% and 48.9% of P.aeruginosa isolates were resistant to imipenem,meropenem and ceftazidime, respectively.Pandrug-resistant (PDR) P.aeruginosa was isolated from our hospital.All strains of A.baumannii were sus- ceptible to imipenem and meropenem.About 37.7% of A.baumannii were resistant to cefoperazone-sulbactam.Twenty-nine strains showed the same resistant pattern among non-susceptible strains of A.baumannii,mainly derived from 2 clones by PFGE analysis.Conclusions The surveillance results suggest that prevalent strain resistant to cefoperazone-sulbactam may pres- ent in some ICUs.Resistance rate to cefoperazone-sulbactam increased significantly.

Objective To investigate the utility of P504S(?-methylacyl-COA racemase), CK34?E12,p63 and PSA immunohistochemistry in the pathological diagnosis of prostatic adenocarcinoma (PAC).Methods The specimens of 46 cases of PAC,8 cases of prostatic high-grade intraepithelial neo- plasia (HGP1N) and 35 cases of benign prostatic hyperplasia (BPH) tissues were immunohistochemically stained with P504S,CK3413E12,p63 and PSA antibody,respectively.Results Of the 46 PAC cases,42 (91.3%) cases showed positive for P504S,including 25 cases (54.3%) who showed strongly and diffusely positive (+++) for cytoplasmic staining.In 7 (87.5%) of the 8 HGPIN cases,the specimens were also positive for P504S,and only 1(2.9%)of the 35 BPH cases showed focally weakly positive (+) for P504S.All the 8 HGPIN cases (100%) and 33 (94.3%) of the 35 BPH cases showed positive for CK34?E12 and p63,while all the 46 PAC cases showed negative for CK34?E12 and p63.In 44 (95.7%) of the 46 PAC cases,the specimens were positive staining for PSA.Conclusions P504S has high sensitivity and good specificity in the diagnosis of PAC.P504S staining in combination with HE,CK34?E12,p63 and PSA staining can improve the accurate diagnosis of PAC.

BACKGROUNDTo investigate whether neoadjuvant chemotherapy (MVP) could influence the safety of perioperative patients with non-small cell lung cancer (NSCLC).

METHODSThe regimen of chemotherapy was MVP (mitomycin+vindesine+cisplatin) for all patients. The patients undergoing 2 cycles of neoadjuvant chemotherapy, radical resection and 2 cycles of postoperative chemotherapy were compared with those undergoing similar resections and 4 cycles of similar postoperative chemotherapy.

RESULTSOf the 107 eligible patients, 66 patients were in the neoadjuvant-chemotherapy group and 41 in control group. There was no statistical difference between these two groups in the distributions of gender, age, tumor staging and pathology. The neoadjuvant-chemotherapy group had longer operative duration (P=0.262), more operative blood loss (P=0.704), more amount of operative transfusion (P=0.811) and total amount of perioperative transfusion (P=0.074), and less amount of post-operative drainage (P=0.061) than those of the control group, but no statistical difference was found among them. No statistical difference was detected between two groups in the mortality (P=0.674) and the morbidity such as arrhythmia (P=0.608), bronchial parietal fistula (P= 0.378 ), pneumonia (P=0.622) and respiratory failure (P=0.285).

CONCLUSIONSNeoadjuvant chemotherapy does not exert significant influence on the safety of perioperative patients with NSCLC.

Objective:To explore the effect of intragastric administration of diphenoxylate on inducing epilepsy in mice, as well as the changes in neurobehavioral and hippocampal neurons in mice.Methods:Forty C57 male mice aged 2-3 weeks were selected and divided into control group and diphenoxylate group using random number table method, with 20 mice in each group. The mice in the diphenoxylate group were given diphenoxylate (200 mg/kg) by gavage once a day for 14 consecutive days, while the control group mice were given an equal volume of 0.9% sodium chloride solution every day. After each gavage, the seizure status of mice within 2 hours was observed and the mice were graded based on the Racine score. Open field test, elevated cross test, and Morris water maze test were used to observe the neurobehavioral activities of mouse.A digital electroencephalogram machine was used to monitor the epileptic seizures of mice induced by diphenoxylate.Nissl staining was used to observe the damage of hippocampal neurons in mice.SPSS 25.0 software was used for statistical analysis of the data, and independent sample t-test was used for pairwise comparison. Results:The Racine grading results showed that the mice in diphenoxylate group exhibited grade 2 and 3 seizures at 1 hour after gavage. The EEG monitoring results showed that compared with before gavage, the frequency and amplitude of brain waves of mice in diphenoxylate group increased.In the open field test, the residence time in the central region of mice in diphenoxylate group was significantly lower than that of the control group ((12.21±3.37)s, (17.05±4.34)s, t=3.29, P<0.01). In the elevated cross test, the residence time in the open arm of mice in diphenoxylate group was significantly lower than that of the control group ((17.36±5.41)s, (26.70±9.06)s, t=3.31, P<0.01). In the Morris water maze test, the residence time in the platform quadrant of diphenoxylate group was significantly lower than that of the control group((22.08±6.76)s, (27.64±4.60)s, t=2.54, P<0.05). The residence time and the number of stays in the platform area of diphenoxylate group were both significantly lower than those of the control group(both P<0.05). Nissl staining showed that the number of hippocampal neurons in the CA3 region of mice treated with diphenoxylate was significantly lower than that in the control group((135.67±4.59), (140.67±2.73), P<0.05). Conclusion:Excessive diphenoxylate can induce seizures in mice, and the mice exhibit increased anxiety-like behavior and decreased spatial learning and memory abilities.
