OBJECTIVE:To discuss the characteristics and regularities of adverse drug reactions(ADR)occurring in our hospital.METHODS:A total of 1 451 ADR cases collected by ADR monitoring center in 2007 were analyzed statistically in respect of patients' age,routes of administration,drug category,ADR-involved organs or systems and clinical manifestations etc.RESULTS:Of the 1 451 ADR cases,72.16% of the ADR-inducing drugs were administered by intravenous drip,and most were associated with anti-infective drugs,predominantly penicillins,cephalosporins and quinolones.The ADR manifested predominantly as lesions of skin and its appendants.CONCLUSION:Rational drug use and ADR monitoring should be strengthened to reduce or avoid the occurrence of ADR.

Objective To observe the clinical efficacy of navel acupuncture in treating lumbar spinal stenosis. Method A total of 120 patients with lumbar spinal stenosis were randomized into a treatment group and a control group, 60 cases each. The treatment group was intervened by navel acupuncture based on syndrome differentiation of traditional Chinese medicine, while the control group was intervened by oral administration of Bulleyaconitine A tablets, 10 d as a treatment course, for successive 2 courses. The Visual Analogue Scale (VAS) was observed before and after the intervention, and the clinical efficacies were compared.Result The total effective rate was 98.3% in the treatment group versus 76.6% in the control group, and the between-group difference was statistically significant (P<0.01). The VAS scores were significantly changed after the intervention in both groups (P<0.05); the VAS score in the treatment group was significantly different from that in the control group after the treatment (P<0.05).Conclusion Navel acupuncture is an effective approach in treating lumbar spinal stenosis.

Aim To investigate the effect of preventive administration of icariin on learning and memory abili-ties and brain mitochondrial oxidative stress in senes-cence-accelerated mouse prone8 ( SAMP8 ) . Methods
The 6-month-old SAMP8 mice were randomly divid-ed into the SAMP8 model group, ICA groups (75, 150 mg · kg-1 ) , the positive Diethylstilbestrol ( DES ) group and estrogen receptor inhibitor ICI182780 com-bined with ICA (150 mg·kg-1 ) group, with 8 mice in each group. 8 same month old SAMR1 mice were selected as the normal control group. After oral admin-istration for 8 weeks, Morris water maze test and step-down passive test were used to investigate the effects of preventive administration of ICA on learning and mem-ory abilities in SAMP8 mice. Cerebral cortex mitochon-dria were isolated to determine the effect of preventive administration of ICA on the oxidative stress by detec-ting reactive oxygen species ( ROS) level, lipid perox-ides ( MDA ) content, glutathione GSH content and catalase ( CAT ) activity. Results Preventive treat-ment of ICA could significantly improve the abilities of place navigation and space exploration of SAMP8 mice, enhance their reflex ability in step-down passive test. ICA could also reduce the level of ROS and MDA content, increase GSH content in brain mitochondria of SAMP8 mice. CAT activity was not obviously changed. Compared with ICA high dose group, the learning and memory abilities of mice in ICA and estrogen receptor inhibitor ICI182780 co-administrated group were signif-icantly decreased. However,brain mitochondria oxida-tive stress was not changed obviously. Conclusion Preventive administration of icariin can significantly improve learning and memory abilities and brain mito-chondrial oxidative stress in SAMP8 mice. The mecha-nism of ICA improving learning and memory abilities may be related to its estrogen-like effect;while the ac-tion on brain mitochondrial oxidative stress may be in-dependent of estrogen receptor.

ObjectiveTo explore the relationship between the core self-evaluations,copying style and learning engagement of college students.Methods 250 college students were asked to complete the core self-evaluations scale,copying style scale and learning engagement scale.ResultsBivariate correlations results indicated that there was significantly positive correlation between the core self-evaluations,copying style and learning engagement in college students( r=0.179 ～ 0.586,P＜ 0.05 ) ; core self-evaluations affected motivation indirectly by the copying style; core self-evaluations had a direct influence on vigor and absorption; core self-evaluations had a indirect influence on vigor and absorption.ConclusionCopying style was a full mediator of the relationship of the core self-evaluations and motivation,but copying style partially mediated the relationship of the core self-evaluations and vigor and absorption.

Objective To investigate the associated effect of 125I implantation plus chemotherapy in local recurrent stage Ⅲ NSCLC patients.Methods From January 2006 to January 2009,34 patients documented with local recurrent stage Ⅲ NSCLC were divided into two groups by random number table.The treatment group was treated with 125I permanent implantation combined with DP regimen (docetaxel 60 mg/m2 + cisplatinum 75 mg/m2),while the control group received only DP chemotherapy.According to the TPS,the treatment group received CT-guided percutaneous implantation of 125 I seeds with a particle activity of 2.22 ×107-2.59 × 107 Bq.The prescribed dose was in the range of 90-110 Gy and the postoperatively matched peripheral dose (mPD) and D9o were verified by TPS.The control group received a DP chemotherapy regime for 4 cycles after the procedure.This study was approved by the ethics committee,and all patients signed informed consents.The follow up time was up to disease progression.Kaplan-Meier survival analysis was used to describe the local lesion control (LLC) time and progression free survival (PFS).Log-rank test was used in the comparison of the survival rates between the two groups.Fisher's exact test was used to analyze the differences of CR rate and recent efficiency between two groups.Results In the treatment group,postoperative mPD was 93.9-130.4 (M 116.7) Gy,and D90 was 103.6-148.2 (M 130.6) Gy.The LLC time was 4.7 to 24.0 months with a median of 11.6 (95％ CI:8.7-14.6) months.In two cases,there was no recurrence during the follow-up time of 24 months.PFS was 4.7 to 24.0 months with a median of 10.5 (95％ CI:7.4-13.6) months.The recent effective rate of the treatment group was 64.7％ (11/17).CR,PR,SD and PD were 41.2％ (7/17),23.5％ (4/17),23.5％ (4/17) and 11.8％ (2/17),respectively.In the control group,the LLC time was 4.5 to 11.4 months with a median of 7.5 (95 ％ CI:6.7-8.3) months,and the median of PFS was 6.5 (4.5-10.5) (95％ CI:5.7-8.3) months.The response rate,CR,PR,SD and PD were 41.2％ (7/17),5.9％ (1/17),35.3％ (6/17),35.3 ％ (6/17) and 23.5％ (4/17),respectively.There was no statistical significance of the recent effective rate between the treatment group and control group (P =0.30),but the LLC time (x2 =8.40,P ＜ 0.01),the median of PFS time (x2 =6.27,P ＜ 0.05) and CR (P =0.04) of the treatment group were all significantly higher than those of the control group.Concltusion The implantation of 125I seeds combined with chemotherapy for recurring stage Ⅲ NSCLC patients is safe and effective,and its efficacy is superior to the second line chemotherapy alone.

BACKGROUND: Apoptosis plays a key role in intestinal mucosal ischemia-reperfusion injury and recovery; meanwhile, effect of shenfu injection on apoptosis of intestinal epithelial cells during intestinal mucosal ischemia-reperfusion injury should be studied further.OBJECTIVE: To investigate the relationship between the apoptosis of intestinal epithelium and characteristics of intestinal mucosal ischemia-reperfusion injury and recovery.DESIGN: Randomized controlled animal experiment.SETTING: Department of General Surgery, Xianning Central Hospital;Department of General Surgery, Renmin Hospital of Wuhan University.MATERIALS: The experiment was carried out in the Central Laboratory,Xianning Central Hospital from March to August 2005. Fifty-four healthy male SD rats weighting 200-250 g were provided by Animal Center of Medical School, Wuhan University.METHODS: The rats were divided randomly into 3 experimental groups:control group (n=6), ischemia-reperfusion group (n=24) and shenfu treatment group (n=24). ① Pentobarbital sodium solution (40 mg/kg) was administrated into the intraperitoneal cavity to induce anaesthesia. Through a midline abdominal incision, the mesenteric blood vessel of a 15-cm segment of mid-intestine was occluded for 60-minute with an atraumatic vascular forceps. The control group underwent the same procedure except for unblocking the mesenteric blood vessel. At the end of 60 minutes ischemia period the forceps was removed to allow reperfusion, the abdominal cavity was closed. ShenFu injection (8 mL/kg ·h, 20 mL/kg ·d, produced from Yaan Three-Nine Pharmaceuticals Co, No: 030302) was injected 30 minutes before occlusion in SF treatment group, same quantity of 0.9% natrii chloride was injected in control group and ischemia-regeneration group at the same time, and oxygen was inbreathed during the operation and ischemia-regeneration. ② Experimental intestinal canals were sampled for the following analysis when all groups were respectively performed sham ischemia for 1 hour, intestinal ischemia for 1 hour and reperfusion for 1, 24and 72 hours. Sections were observed in light microscope. Histological mucosal damage in each sample was evaluated as followed scoring system: 0score, normal muscosal villi and gland; 1 score, slight lesion near the tip of the villi; 2 scores, slight lesion of subepithelial gland; 3 scores, development of subepithelial (Gruenhagen) spaces near the tip of the villi with capillary congestion; 4 scores, extension of the subepithelial space with moderate epithelial lifting from the lamina propria; 5 scores, a few denuded villous tips; 6 scores, massive denuded villi; 7 scores, denuded villi with exposed lamina propria and obvious gland lesion; 8 scores, disintegrateon of the lamina propria; 9 scores, haemorrhage and ulceration. ③ The Tunel method (TdT mediated biotin-dUTP nick and labeling; TdT-Frag EL DNA fragmentation detection kit) was used. Inbrief, this method allowed the identification of apoptosis nuclei in tissue samples through DNA fragment and labeling. Apoptosis Index (AI) was set as the average number of apoptosis cells in per 100 cells by observing ten high power fields of adjacent villi and crypts. ④ The mitotic phase of crypt epithelial nucleus within intestinal mucosa was observed in intestinal sections stained with haematoxylin and eosin. The number of cells with nucleus mitotic phase was counted in ten adjacent mucosal crypts, which was taken as the index of mitotic activity of intestinal mucosal epithelial cell.MAIN OUTCOME MEASURES: Intestinal mucosal histopathological changes, apoptosis of intestinal mucosal epithelial cell and mitotic activity of intestinal mucosal crypt.RESULTS: All 54 rats were involved in the final analysis. ①) Scores of histopathological changes were (0.65 ±0.35) points in 1-hour ischemia group, (3.87±0.86) points in 1-hour reperfusion group and (0.65±0.35)points in 24-hour reperfusion group; which were lower than those in ischemia-reperfusion group [(7.11±1.01), (8.05±1.34), (1.53±0.48) points; P＜ 0.05]. ② Indexes of apoptosis were 17.24±7.05 in 1-hour ischemia group, 24.20±9.87 in 1-hour reperfusion group, 11.49±4.71 in 24-hour reperfusion group and 6.02±2.16 in 72-hour reperfusion; which were lower than those in ischemia-reperfusion group (51.09±13.76, 54.89±15.58,23.54±9.64, 12.47±5.52; P ＜ 0.05). Activities of mitosis were 10.37±2.03and 11.72±2.07 in 1-hour ischemia group and 1-hour reperfusion group,respectively; which was higher than those in ischemia-reperfusion group(8.24±1.69, 9.95±1.93; P ＜ 0.05).CONCLUSION: Shenfu injection can significantly attenuate apoptosis of intestinal epithelium, increase crypt mitotic activity, and promote intestinal epithelium regeneration or repair.

ObjectiveTo determine the current students' social anxiety status and maternal factors in school students( grade 5-7) in Harbin,and provided scientific guidance relevant to students'social anxiety.Methods 1526 mother-child pairs collected by random cluster sampling,children completed the social anxiety scale for children (SASC),security scale,coping strategies questionnaire( consist of ambivalence and avoidance subscale),acceptance scale and psychological control scale,and mothers completed the center for epidemiologic studies depression inventory (CES-D),self-rating anxiety scale (SAS).ResultsThe total positive detection rate of social anxiety was 13.6％,there was no significantly difference between boys and girls (P ＞ 0.05) ; the positive detection rate of Grade 6 was higher than Grade 5 and Grade 7.There were positive correlation between social anxiety and mother's psychological control,mother's depression,mother's anxiety ( r =0.228,0.143,0.122) ; negative correlation with mother's acceptance( r =-0.214).Linear regression indicated that only three variables (mother's psychological control,mother's acceptance,mother's depression) were at the P ＜ 0.05 level.The regression coefficients for the three variables were 1.557,- 1.092 and 0.040,respectively.ConclusionMaternal highly psychological control,lowly acceptance and maternal anxiety depression all play a role in promoting the occurrence of students' social anxiety.

Objective To know the effect of pre-hospital emergency care for patients with acute cranio-cerebral injury. Methods Selected 312 patients with acute cranio-cerebral injury from Jan of 2005 to Jan of 2009 as the emergency group, selected 285 patients with acute cranio-cerebral injury from Jan of 2000 to Dec of 2004 as the control group. Retrospective analized the clinical condition between the two groups to know the effect of pre-hosptial emergency cares. Results There was significant difference of dead rate betweent the two groups, the prognosis of the two groups was also different. Conclusions Effective pre-hospital emergency care is very important for patients with acute eranio-cerebral injury, which can avoid certain complications and reduce dead rate.

Aim To investigate the effects of Ginkgo biloba extract(EGB)on tumor necrosis factor-alpha(TNF-?)in TNBS-induced colitis in rats and its mechanisms.Methods Colitis in rats was induced by colonic administration with 2,4,6-trinitrobenzene sulfonic acid(TNBS).Wistar rats were randomly divided into four groups,10 in each:normal group,model group,5-aminosalicylic acid(5-ASA group)and Ginkgo biloba extract group(EGB group).The levels of nitric oxide(NO),and glutathion peroxide(GSH-Px)were measured by biochemical methods.The expressions of TNF-? and nuclear factor kappaBp65(NF-?Bp65)in the colon tissues of colitis rats were detected by means of immunohistochemistry.The expressions of induce nitric oxide synthase(iNOS)in the colon tissues of colitis rats were detected by reverse transcription polymerase chain reaction(RT-PCR).The effects of EGB on colonic inflammation and macroscopic and histological damage were evaluated as well.Results Compared with the model group,treatment with EGB for 4 weeks significantly reduced colon macroscopic and histological damage,elevated the activities of GSH-Px and reduced the contents of NO,inhibited the protein expressions of TNF-? andNF-?Bp65,and decreased the mRNA levels of iNOS in the colon tissues of experimental colitis.Conclusions The probable mechanisms of EGB was that it ameliorated inflammatory injury in TNBS-induced colitis in rats by its reduction of TNF-?,NF-?Bp65 and iNOS levels.Then EGB could curb the inflammatory cascade effects of inflammatory mediators to protect ulcerative colitis.
