Objective To observe the effect of compound Epi medium injection(CEI )on focal cerebral ischemia in rats.Methods Sixty Sprague -Dawsley rats were ran domly allocated to six groups:mimic operation group(n=10),model group(n=10),tetramethylpyrazine injection gro up(n=10),CEI groups(treated with large -,moderate -and small -dose of CEI respectively).Focal cerebral ischemia in rats was induced by occlusion of right middle cerebral artery and the effects of CEI on plasm a levels of TXA 2 and PGI 2 ,platelet aggregation ,SOD and MDA a ctivities and infarct size of brain were observed.Results CEI could increase PGI 2 level in plasma,lower platelet aggregation rate,increase SOD activity,decrease TXA 2 level and MDA content and lessen the i nfarct size of brain.Conclusion CEI can keep the balance of TXA 2 -PGI 2 ,inhibit platelet aggregation and i ncrease the volume of cerebral blood flow.Meanwhile,it can also elimi-nate oxygen free radicals,improve cerebral function and relie ve ischemic damage induced by acute c erebral infarction.

Objective To analyze the risk factors of subclavian venous catheter-related infections in patients with traumatic hemorrhagic shock (THS) and provide a basis for prevention and control of the infection. Methods A retrospective study was conducted. 357 patients with THS and indwelling of subclavian vein catheter admitted in the Department of Emergency of Affiliated Hospital of Sichuan Provincial Luzhou Medical College were enrolled, and according to the infection state, they were divided into infection group (56 cases) and non-infection group (301 cases). The patients' data of gender, age, history of underlying disease, catheter position, catheter indwelling time, time staying in hospital, situation of antimicrobial drug used, application of tracheotomy or not, white blood cell count (WBC) levels, etc were collected for univariate analysis. The resulting indexes with statistical significance were applied for carrying out the multivariate logistic regression analysis, and then the independent risk factors involved in the development of subclavian venous catheter-related infections in the shock patients could be screened out.Results In 357 patients with THS, 56 were infected (15.7%). Univariate analysis showed: age ≥ 60 years (χ2 = 19.839,P < 0.001), with diabetes mellitus in past history (χ2 = 6.252,P = 0.012), catheter indwelling time ≥ 7 days (χ2 = 19.261,P < 0.001), time staying in hospital ≥ 7 days (χ2 = 4.315,P = 0.038), time for use of antimicrobial drug≥ 7 days (χ2 = 16.161,P < 0.001), tracheotomy (χ2 = 40.969,P < 0.001), WBC < 4×109/L (χ2 = 39.451,P < 0.001) and the disease severity grade 4 - 5 (χ2 = 8.345,P = 0.004) were the risk factors of subclavian venous catheter-related infections in patients with THS. Multivariate analysis showed: catheter indwelling time ≥ 7 day [odds ratio (OR) = 16.713, 95% confidence interval (95%CI) 3.651 - 76.624), tracheotomy (OR = 6.861, 95%CI 2.377 - 18.246), WBC < 4×109/L (OR = 4.903, 95%CI 1.887 - 12.643) were the independent risk factors of subclavian venous catheter-related infections in THS patients.Conclusion The strict implementation of aseptic catheterization, shortening the time of catheter indwelling as much as possible and the rational use of antibiotics can effectively reduce and prevent the incidence of venous catheter-related infection in THS patients.

This study was aimed to explore factors related to microalbuminuria of early stage of diabetic nephropathy (DN). Through epidemiologic survey, syndrome data of patients with early stage of DN were collected. The analysis was made on relationship between MAU (strain) of early stage of DN patients and the influencing factors (variable) with logistic regression analysis. The influencing factors were investigated in the early stage of DN patients in MAU. The epidemiological study showed a close relationship between factors such as active living style, easy irritability, drinking, old age, long disease course, phlegm and dampness body constitution, qi-stagnation body constitution, purple or dark tongue, thin and rapid pulse, yin deficiency and heat pattern, qi-yin deficiency pattern, cold and dampness pattern with the incidence of early stage of DN. It was concluded that there were 114 cases of early stage of DN with MAU of 20-52 μg·mL-1. The risk factors contained easy irritability, qi-stagnation body constitution, purple or dark tongue, yin deficiency and heat pattern, qi-yin deficiency pattern, as well as cold and dampness pattern. The protective factor contained active living style. There were 95 cases of early stage of DN with MAU of 53-199 μg·mL-1. The risk factors contained drinking, old age, long disease course, phlegm and dampness body constitution, as well as thin and rapid pulse.

Objective To compare the efficiencies of enteral nutrition with nasogastric tube with that of enteral nutrition with endoscopic gastrostomy tube in ICU long-term bedridden patients. Methods A total of 6 patients who were admitted in our ICU between January 2008 and September 2009 were enrolled in this study. The expected completion of daily calorie supply, completion of total volume of nutrient fluid feeding, nutrient fluid backstreaming condition, and incidence rate of tube obstruction were compared between those supported with nasogastric tube and endoscopic gastrostomy tube. Results The completion of daily calorie supply and completion of total volume of nutrient fluid feeding were significantly superior in patients who were supported with endoscopic gastrostomy tube than those with nasogastric tube (P = 0. 002 and P = 0. 008, respectively). In addition, nutrient fluid backstreaming condition and incidence rate of tube obstruction were significantly lower than with nasogastric tube (P= 0. 011 and P = 0. 021, respectively). Conclusion Enteral nutrition with endoscopic gastrostomy tube is more efficient in reaching the nutrition support target than with nasogastric tube.

Objective To evaluate the validity and reliability of the Chinese version of Alcohol Withdrawal Scale (AWS). Methods Totally 175 patients diagnosed as alcohol dependence according to the criteria of ICD-10 were studied. Intraclass correlation coefficient (ICC) analysis was applied for examining interrater consistency and Cronbach' s α for internal consistency. Factor analysis was used to examine the construct validity. Correlation analysis between AWS and CGI,Revised Clinic Institute Alcohol Withdrawal Syndrome Scale(CIWA-Ar) were conducted to evaluate the criterion validity. Based on clinical criteria,ROC curve was calculated so as to test the discriminative ability and establish the cut-off point of the scale. Results ( 1 ) Reliability: ICC value was 0.93,and Cronbach's α was 0.83,which indicated good interrater and internal consistency. (2) Validity:the correlation coefficients of the two subscale with the total scale score were 0.78,0.83 respectively. The correlation coefficients between the subscale were 0. 81 and factor analysis revealed that each item of the scale had relatively high load on the primary factor (0.409 ～0.926). At the time of admission,the total score of the AWS was positively correlated with that of CGI ( r = 0.71, P < 0.05 ). The total score of the AWS also was positively correlated with that of CIWA-Ar ( r = 0. 86, P<0. 05). As treatment went on,total score of the AWS showed a downward trend,at the end of the first week,the total score of the AWS was positively correlated with that of CGI ( r = 0.62, P<0.05). (3)The cut-off point of AWS for mild alcohol withdrawal state was determined as ≥3. With this cut-off point,AWS had both high sensitivity (92.1% ) and specificity (73.5% ) ,and the area under curve (AUC) was 0. 91. The cut-off point of AWS for moderate withdrawal state was determined as ≥7, and the sensitivity and specificity of AWS were 94.3 % and 89.7 % respectively, with the AUC of 0.94. The cut-off point of AWS for severe withdrawal state was determined as ≥ 10. With this cut-off point AWS had both high sensitivity (94. 9% ) and high specificity (92.6% ) .with the AUC of 0.93. Conclusion AWS has good reliability and validity and can reflect the change of the disease and the efficacy of treatment.

Objective To investigate the effects of risperidone and its active metabolite, paliperidone (9-hydroxyrisperidone), on hyperactivity and deficient sensorimotor gating induced by MK-801 in rats. Methods Adult male Sprague-Dawley (SD) rats (n=96) were used in this study. The effects of risperidone (0.1 mg/kg) and paliperidone (0.05, 0.10 and 0.20 mg/kg) on MK-801-induced (0.40 mg/kg) hyperactivity were examined in 48 rats with with 8 animals per group.The effects of risperidone(0.5 mg/kg)and paliperidone(0.10,0.50,1.00 mg/kg)on MK-801-induced (0.25 mg/kg) deficit in prepulse inhibition (PPI) were examined in 48 rats with 8~10 animals per group. Results Risperidone (0.10 mg/kg) and paliperidone (0.05 mg/kg) diminished the MK-801-induced hyperactivity (P<0.05). But paliperidone (0.10, 0.20 mg/kg) group did not affect locomotor activity compared to the control group. Risperidone (0.10 mg/kg) and different doses of paliperidone (0.10, 0.50, 1.00 mg/kg) enhanced the PPI baseline in rats. However, only risperidone (0.10 mg/kg), but not paliperidone restored the MK-801-induced deficits in PPI. Conclusion Risperidone and paliperidone have different pharmacological actions on MK-801-induced hyperactivity and deficits in prepulse inhibition in rats, suggesting that pharmacological actions of paliperidone are different from those of risperidone, although paliperidone is the active metabolite of risperidone.

Objective To investigate the effects of repeated neonatal administration of dizocipline maleate (MK-801), the N-methyl-D-aspartate (NMDA) receptor antagonist, on the expression of NMDA receptor subunits NMDAR 1 (NR1), NMDAR2A (NR2A), NMDAR2B (NR2B) and the protein levels of nerve growth factor (NGF) in neonatal rats. Methods Neonatal Sprague-Dawley (SD) rats were randomly divided into research group and control group, with 15 ani-mals in each group. Rats were administrated subcutaneously with MK-801 or normal saline from postnatal day (PND) 5 to PND14 (0.25 mg/kg, twice a day). The expression levels of NR1, NR2A, NR2B and NGF were examined on PND15, PND42 and PND70 in the prefrontal cortex and hippocampus. Results At PND15 (neonatal period), there were no signifi-cant differences in the expression levels of NR1, NR2A, NR2B and NGF in the prefrontal cortex and hippocampus be- tween the two groups (P>0.05). At PND42 (adolescence), NGF protein levels in the prefrontal cortex was significantly low-er in research group than in control group [(56.19±37.87) vs. (152.54±53.92), P<0.01]. At PND70 (adulthood), the expres-sion of NR1, NR2A in the hippocampus was significantly higher in research group than in control group [NR1:(149.55%± 27.00%) vs. (100.00%±32.08%);NR2A:(171.54%±19.85%) vs. (100.00%±51.04%). P<0.05]. Conclusion Neonatal re-peated treatment of MK-801 increases the expression of NMDA receptor subunits NR1, NR2A in the hippocampus in adulthood while decreases the expression of NGF in the prefrontal cortex in adolescence, suggesting that neonatal block-ade of the NMDA receptor may influence the growth and development of the nervous system.

Objective To investigate the clinical efficacy of combination treatment of Ambroxol,Ipratropium and Budesonide during perioperative period in elderly patients with cardiac adenocarcinoma and chronic obstructive pulmonary disease(COPD).Methods A total of 126 elderly patients aged over 65 years diagnosed as cardiac adenocarcinoma and COPD were selected,and no chemotherapy was given to them before operation.Patients were randomly divided into experimental group(n＝ 62)and control group(n＝ 64).Intravenous infusion of Ambroxol hydrochloride and atomizing inhalation of Ipratropium were given in both groups,and the experimental group received budesonide additionally.The pulmonary function,postoperative pulmonary atelectasis,pulmonary infection,antibiotics application and hospitalization after operation were compared between the two groups.Results The forced expiratory volume at the first second(FEV1),forced vital capacity(FVC)and FEV1/FVC were higher in experimental group than in control group [(1.79 ± 0.52)1 vs.(1.33 ± 0.38)L,(2.44 ±0.43)Lvs.(1.93 ± 0.36)L and(73.91 ± 8.17)％ vs.(62.87 ± 7.23)％,respectively,allP＜0.05].The postoperative pulmonary atelectasis and pulmonary infection were lower in experimental group than in control group(4.8％ vs.15.6％,6.5％ vs.18.8％,respectively,both P＜0.05).The time for antibiotics application after operation had no difference between the two groups[(4.81±1.20) days vs.(5.98 ± 1.17)days,P ＞ 0.05].There was a significant difference in postoperative hospitalization between the two groups [(8.37 ± 0.27) days vs.(11.80 ± 0.33) days,P ＜ 0.05].Conclusions The combination treatment of Ambroxol hydrochloride,Ipratropium and Budesonide during perioperative period achieves better therapeutic effects than does the combination treatment of ambroxol hydrochloride and ipratropium in elderly patients with cardiac adenocarcinoma and COPD.

OBJECTIVE: To assess the association of genomic instability of epithelial cadherin 1 (CDH1) gene and clinicopathological characteristics of gastric cancer. METHODS: In total 120 paraffin-embedded gastric cancer tissue specimen were prepared, and genomic DNA was extracted. The genomic instability of the CDH1 gene was analyzed by immunohistochemistry and silver staining PCR-single-strand conformation polymorphism. RESULTS: The number of information individuals (heterozygotes) was 98 for the D16S752 locus. The detection rates for microsatellite instability (MSI) and loss of heterozygosity (LOH) at the D16S752 locus and the positive rate of CDH1 protein were 19.39%, 16.33% and 51.02%, respectively. The detection rate of MSI in TNM stages I or II was significantly higher than that in stages III or IV (P<0.05) while the detection rate of LOH was significantly lower than that in stages III or IV (P<0.05). The positive rate of CDH1 protein in TNM stages III or IV was significantly lower than that in stages I or II (P<0.05). The detection rate of MSI of cases with lymph node metastasis was significantly lower than that of without lymph node metastasis (P<0.05) while the detection rate of LOH was significantly higher than that without lymph node metastasis (P<0.05). The positive rate of CDH1 protein in patients with lymph node metastasis was significantly lower than that in patients without lymph node metastasis (P<0.05). The positive rate of CDH1 protein in MSI-positive group was significantly higher than that in MSI-negative group (P<0.05), and the positive rate of CDH1 protein in the LOH-positive group was significantly lower than that the LOH-negative group (P<0.05). CONCLUSION The genomic instability of the CDH1 gene is associated with the progression of gastric cancer. MSI at the D16S752 locus may be used as a molecular marker for early gastric cancer, while LOH at this locus mostly occurs in advanced gastric cancer and can be regarded as an effective indicators for malignancy evaluation and prognosis.
