The similar(coefficients) of 2 isolates among the 7 ECO isolates from the gastroenterology ward and 2(isolates)(among) the 18 ECO isolates from the respiratory ward were more than 90%.The isolates whose similarity was more than 90% were also found in other wards.CONCLUSIONS There are vertical disseminations of single clone of ESBL-producing organisms in several wards,especially in the ICU.It is necessary to strengthen the management of(infection)-control.

Objective To compare the vibrating perception threshold (VPT) between normal subjects and subjects with cervical spondylosis of nerve root type, and to observe the clinical efficacy of acupoint injection at Quyuan (SI13) in releasing pain in cervical spondylosis of nerve root type.Method Sixty-three patients with cervical spondylosis of nerve root type were recruited and randomized into a treatment group of 35 cases and a control group of 28 cases. The treatment group received acupoint injection at Quyuan, and the control group received acupoint injection at Jiaji (EX-B2) points. The short-form McGill Pain Questionnaire (MPQ) was adopted. From the questionnaire, the Pain Rating Index (PRI), sensory (S), affective (A), and total (T) pain rating indexes, Visual Analogue Scale (VAS), and Present Pain Index (PPI) were used to comprehensively evaluate the pain improvement and to quantify the therapeutic efficacy, and the VPT was also considered. The Clinical Assessment Scale for Cervical Spondylosis (CASCS) by West China Rehabilitation Center was also used to analyze the result in the treatment group.Result After the intervention, the MPQ and VAS scores in the treatment group were significantly lower than those in the control group (P<0.05). The total effective rate of the treatment group was significantly higher than that of the control group (P<0.05). Meanwhile, the VPT was improved after the treatment.Conclusion Acupoint injection at Quyuan can produce a more significant efficacy than at Jiaji (EX-B2) in treating cervical spondylosis of nerve root type.

AIM　To explore whether dexamethasone-dextran (260 000) has the characteristics of site-specific delivery in rat gastrointestinal tract. METHODS　Dexamethasone prodrug and dexamethasone were administered to rat ig at the dose of 5 μmol*kg-1. The distribution of dexamethasone in the contents and mucosa of different parts of the rat GI tract at different time intervals and its concentration in plasma were determined by HPLC. RESULTS　Dexamethasone was mainly released in the cecum and colon contents and mucosa after oral administration of dexamethasone prodrug. The absorption was reduced significantly. The peak time of the drug in plasma was 8.1 h, and the peak concentration was 32 μg*L-1. However, free dexamethasone was found mainly in the contents and mucosa of the stomach, proximal and distal small intestine. The peak time of the drug in plasma was 2.2 h, and the peak concentration was 2120 μg*L-1. CONCLUSION Dexamethasone can be specifically delivered to the large intestine by using dexamethasone-dextran (260 000). It appears that the prodrug has a potential in the treatment of inflammatory bowel disease.

Objective To discuss the clinical effect of neoadjuvant chemotherapy combined tumor cells to destroy the loss in treatment of patients with advanced ovarian cancer.Methods One hundred and forty-four patients with advanced ovarian cancer were divided randomly into the control group(n=72) and research group (n=72).The patients of control group were given conventional chemotherapy(ovarian tumor remove first and then neoadjuvant chemotherapy) and the patients of research group were given neoadjuvant chemotherapy (neoadjuvant chemotherapy first and then ovarian tumor remove).The operation time, intraoperative blood loss, hospital stay, ideal reduction rate, clinical efficacy and postoperative complications between the two groups were compared.Results The operation time, intraoperative blood loss, hospital stay of the research group were obviously lower than that of the control group((124.6±21.3) min vs.(186.4±32.6) min, (382.5±62.3) ml vs.(618.5± 86.4) ml, (8.9± 1.3) d vs.(12.2± 3.4) d;t =5.623,9.646,5.257), while the ideal reduction rate of the research group were obviously higher than that of the control group(70.8％ vs.47.2％, x2 =8.735), the differences were statistically significant(P＜0.05).The clinical efficacy(87.5％ vs.52.8％, x2 =6.748) of the research group were obviously higher than that of the control group, while the postoperative incision infection (9.7％ vs.19.4％, x2 =4.452) and fever(4.2％ vs.15.3％,x2 =5.536) were obviously lower than that of the control group, the differences were statistically significant (P＜0.05).Conclusion The treatment of neoadjuvant chemotherapy can obviously increase the the clinical effect of treatment of patients with advanced ovarian cancer and decrease the postoperative complications, it is worth popularization and application.

Objective To explore the difference of four calculating methods used to determine the obesity. Methods Two thousand four hundred and forty six (2446) men and three hundred and seventy nine (379) women were measured height and body mass, Standard body mass, BMI, body fat ratio and obesity index(OI) were calculated with formula. According to the BMI≥ 25 kg/m2 , BMI ≥ 27 kg/m2 and BMI≥28 kg/m2, the obese adults were 1419,680 and 435 respectively;there were 649 adults that their body mass was over 20％standard body mass; there were 639 adults that their body fat ratio was over 25％(male)and 33％(female). Results For obesity determination, the adults who were 20％overweight and over standard body fat ratio were significantly different from those whose BMI were over 25 kg/m2 ( P＜0. 05 ) ;Those who were 20％overweight and over standard body fat ratio were not significantly different from those whose BMI were over 27 kg/m2 ( P＞0.05 ) ; Those who were 20％overweight and over standard body fat ratio were significantly different from those whose BMI were over 28 kg/m2 ( P＜0. 05 ). Conclusion Determining obesity with BMI≥27 kg/m2 is feasible and rational.
