OBJECTIVETo investigate the reasonable proposal of prophylactic antibiotics use in selective colorectal operation.

METHODSOne hundred and sixty-five patients underwent colorectal surgery were randomized to Treatment 1 (55 cases), Treatment 2 (50 cases) and Control (60 cases) group. The Treatment 1 group was given oral MgSO4 solution at the night before operation, and Cefradine 2.0 g (I.V.) during the induction of anesthesia, continued with tow times of intravenous Cefradine 2.0 g and 0.5% Metronidazole 100 ml at an interval of 12 hours in 24 hours after the operation. The Treatment 2 group was given the same treatment as Treatment 1, but the antibiotics would not be withdrawn until 3-5 d after operation. On the basis of the treatment of Treatment 2 group, the Control group was given oral antibiotics 2-3 days before operation. Postoperative complications including surgical site infection, stoma leakage, dysbacteriosis, and WBC, body temperature, days of hospitalization and antibiotic expenses in the three groups were observed and compared.

RESULTSThere was no significant differences in surgical site infection, stoma leakage, WBC counting and its change, body temperature and hospital stay among the three groups (P > 0.05). The incidence rate of dysbacteriosis in Control group was significantly higher than that in Treatment 1 group (P < 0.05). The antibiotic expenses in the Treatment 1 group was significantly lower than those of the other two groups (P < 0.05).

CONCLUSIONSProphylactic antibiotic use during the induction of anesthesia and 24 hours after operation was reasonable in selective colorectal operation, it can prevent the surgical site infection effectively with good social-economic effects and fewer side effects.

OBJECTIVETo study the relation between single nucleotide polymorphism(SNP) at the 91T-->A(Phe31Ile) position of the STK15 gene and the susceptibility of esophageal squamous cell carcinoma (ESCC) in She county--a ESCC high incidence region in North China.

METHODSPolymerase-chain reaction(PCR)-restriction fragment length polymorphism (RFLP) analysis was used to detect the genotypes of STKl5 Phe31Ile(91T-->A) SNP, and the samples came from 296 ESCC patients and 302 healthy controls.

RESULTSThe risk of ESCC significantly increased in the group which had been smoking or having a family history of upper gastrointestinal cancer (UGIC) (the OR = 1.68 and 1.77, 95% CI: 1.34-2.10 and 1.44-2.19, respectively). Rates of the three genotypes (Phe/Phe, Phe/Ile, Ile/Ile) of the STK15 Phe31Ile (91T-->A) SNPs in ESCC patients were 11.5%, 34.8% and 53.7%, respectively, and were not significantly different from that in the healthy group (11.9%, 36.8% and 51.3%) (chi2 = 0.35, P = 0.84). When compared to Phe/Phe genotype, Phe/Ile and Ile/Ile of STK15 91T-->A(Phe31Ile)did not show effect on the risk of ESCC according to the odds ratio results which were 0.98 (95% CI: 0.57-1.69) and 1.09 (0.65-1.82) respectively. STK15 91T-->A (Phe31Ile) SNP also did not significantly influence on the development of ESCC even the samples were stratified by sex, smoking status and family history of upper gastrointestinal cancer.

CONCLUSIONThe STK15 Phe31Ile(91T-->A) polymorphisms seemed irrelevant with the risk of ESCC in She county.

OBJECTIVETo examine the reliability and validity of the 66-item version on the gross motor function measure (GMFM-66) to assess the gross motor functions of children below 3 years oldwith cerebral palsy.

METHODS298 valid samples were obtained from 171 children with cerebral palsy (male 126, female 45 with mean age 19 months, age range 3-36 months) measured with GMFM-88. Then a 73-item version of GMFM (GMFM-73) special for these children was obtained by Rasch analysis. Both GMFM-66 and GMFM-73 scores of to each sample were obtained. The reliability and validity of GMFM-66 were evaluated through analyzing the correlation between the scores and between the changed scores of these two GMFM versions. The relative precision of GMFM-73 versus GMFM-66 was also analyzed.

RESULTSSignificant correlations were found between the scores and between the changed scores of these two versions of GMFM. A 14% less gain in relative precision was achieved when using GMFM-73 versus GMFM-66.

CONCLUSIONResults indicated that the GMFM-66 had good reliability and validity in assessing the gross motor functions of children below 3 years old with cerebral palsy.

Objective To investigate the efficacy and safety of Bushen Huoxue Decoction in the treatment of carotid atherosclerotic plaque. Methods Totally 50 patients of carotid atherosclerotic plaque were collected to conduct health education. At the same time, they were given Bushen Huoxue Decoction, one dosage a day, twice a day, decoction, for 12 weeks. The correlation indexes of carotid artery before and after treatment were observed, and TCM syndrome integrals were evaluated before and after 4, 8 and 12 weeks treatment. FBG, TC, LDL-C, CRP HCY, IL-6, IGF-1, and OPG were detected before and after treatment. Hematuria routine, liver and renal function were monitored. Results After treatment, the Crouse score and the plaque grade score of carotid atherosclerotic plaque showed a tendency to decrease, without statistical significance (P=0.060, P=0.336). Carotid maximal plaque area and modified total score of carotid atherosclerotic plaque were significantly reduced compared with that before treatment (P<0.05). TCM syndrome integrals were significantly reduced compared with that before treatment (P<0.05), and the scores decreased significantly with the prolongation of treatment time. TCM syndrome integrals after 4, 8, and 12 weeks were significantly reduced compared with that before treatment (F=160.352, P<0.001). Total effective rate of treatment in the efficacy of TCM syndrome was 85.11％ (40/47). Serum levels of FBG and TC decreased significantly after the treatment compared with that before the treatment, with statistical significance (P<0.05). Serum levels of LDL-C, HCY, CRP, IL-6, IGF-1, and OPG all showed a tendency to decrease, without statistical significance (P>0.05). No abnormality in hematuria routine, liver and renal function examinations were found during the research. Conclusion Bushen Huoxue Decoction has obvious clinical efficacy for carotid atherosclerotic plaque, which can improve clinical symptoms of patients, it also could stabilize and reduce plaque with high safety.

Objective To investigate the clinical and imaging features of patients with Alzheimer' s disease (AD) and vascular dementia (VaD) and find an effective method to make differential diagnosis between the 2 entities. Methods One hundred and sixty-two patients with dementia,admitted to our hospital from August 2006 to June 2011, and 42 patients with dementia found from community epidemiological survey were chosen in our study; their clinical data were retrospectively collected and analyzed; in these patients,114 patients were with AD and 90 patients were with VaD.Mini Mental State Examination (MMSE) was performed on these patients and the cognitive competence,behavioral symptoms and imaging data of these patients were analyzed and compared. Results More female,higher education level and longer course of disease in patients with AD were noted as compared with those in patients with VaD (P＜0.05); the scores of attention and calculation in patients with VaD were obviously lower than those in patients with AD (P＜0.05); the scores of short-term memory,retelling and reading comprehension in patients with VaD were obviously higher than those in patients with AD (P＜0.05); the happening of repeated convergence behavior in patients with AD was much more often than that in patients with VaD (P＜0.05); patients with AD had higher ratio of shrinking hippocampus than patients with VaD, and the incidence of vascular disease in the brain of patients with VaD was significantly higher than that of patients with AD (P＜0.05). Conclusion Substantial differences on clinical and imaging features exist in AD and VaD patients,which can be attributed to the differences of lesion nature and distribution,as well as the underlying pathophysiological procedures of each disease.

Objective To explore the effects of Angiotensin (ANG)-( 1-7 ) on postangioplasty fibrotic remodeling and the involvement of TGF-β/Smad signaling pathway in this process. Methods Thirty two healthy New Zealand white rabbits were randomly divided into 4 groups: sham group, control group,ANG-(1-7) group and ANG-( 1-7 ) + A-779 group. Rabbits underwent angioplasty in the abdominal aorta or sham surgery. Subsequently, an osmotic minipump was implanted for saline, ANG-(1-7) (576 μg· kg~(-1) ·d~(-1)) or ANG-(1-7) + A-779 (576 μg · kg~(-1) · d~(-1)) delivery. Before and after 4 weeks treatment, the levels of ANG Ⅱ in plasma were measured by ELISA. At week 4, angiography and histomorphometric analysis were performed, mRNA levels of collagen Ⅰ and Ⅲ were assayed by RT-PCR and protein levels of TGF-β_1 and Stand2 in local vessel were assayed by Western blot. Results Following 4 weeks treatment,ANG-( 1-7 ) and ANG-( 1-7 ) + A-779 group displayed a significant elevation in lumen diameter [ (4. 11±0.10) mm and (3.34 ±0. 11) mm vs. (2.88 ±0.08) mm,P <0.05, respectively] and reduction in neointimal thickness [ (208 ± 17) μm and (407±25) μm vs. (448 ± 15) μm, P <0. 05, respectively],neointimal area [(0.27 ±0.09) mm~2 and (0.38 ±0.01) mm~2 vs. (0.41 ±0.02) mm~2, P<0.05,respectively] and restenosis rate [(28. 1 ±2.7)% and (36.8 ±2.2)% vs. (40. 1 ±2.7)% ,P<0.05,respectively] compared with control group. Collagen Ⅰ , Ⅲ mRNA and TGF-β_1 , Smad2 protein levels were significantly elevated in control group,ANG-(1-7) group and ANG-(1-7) + A-779 group compared to sham group ( P < 0. 01 or P < 0. 05 ) and reduced in ANG- (1-7) group compared to control group ( all P < 0. 05).Co-treatment with A-779 reversed the inhibitory action of ANG-( 1-7 ) . Plasma levels of ANG Ⅱ postangioplasty were similar in control and ANG-( 1-7 ) group and both were significantly higher than preoperation levels. Conclusion ANG-(1-7) attenuates postangioplasty collagen synthesis in rabbits possibly through down-regulating the expression of TGF-β_1 and inhibiting the activation of Smad2 pathway.

Objective To observe the clinical efficacy of acupuncture combined with acupoint catgut embedding therapy on back-shu and front-mu points and external application on shenque(RN8)point for premature ovarian failure(POF).Methods A total of 62 patients with POF were randomly divided into the observation group and the control group,with 31 patients in each group.The observation group was treated with acupuncture combined with acupoint catgut embedding therapy on back-shu and front-mu points and external application on shenque point,and the control group was treated with hormone replacement therapy.After three months of treatment,the clinical efficacy of the two groups was evaluated,and the changes in the traditional Chinese medicine(TCM)syndrome scores,as well as the ovarian volume,number of antral follicle,and antral follicle diameter of the patients in the two groups before and after treatment were observed.The changes of serum follicle stimulating hormone(FSH),luteinizing hormone(LH)and estradiol(E2)levels before and after treatment were compared between the two groups.Results(1)The total effective rate was 93.55%(29/31)in the observation group and 80.64%(25/31)in the control group.The efficacy of the observation group was significantly superior to that of the control group,and the difference was statistically significant(P＜0.05).(2)After treatment,the serum FSH,LH and E2 levels of patients in the two groups were significantly improved(P＜0.05),and the improvement in the observation group was significantly superior to that in the control group,with statistically significant differences(P＜0.05).(3)After treatment,ovarian volume,number of antral follicle,and antral follicle diameter were significantly improved in the two groups(P＜0.05),and the improvement in the observation group was significantly superior to that in the control group,and the difference was statistically significant(P＜0.05).Conclusion The treatment of POF with acupuncture combined with acupoint catgut embedding therapy on back-shu and front-mu points and external application on shenque point can significantly improve the clinical symptoms of the patients,conducive to the recovery of ovarian function,and significantly improve the sex hormone levels of the patients,with precise clinical efficacy.
