OBJECTIVETo discuss the curative effect of traditional treatment and combination therapy for senile hip fracture.
METHODSUsing prospective methods to choose 300 cases of elderly patients with hip fractures from February 2011 to December 2012, which were randomly divided into comprehensive treatment group and conventional treatment group. After screening, 148 case were in comprehensive treatment group,including 62 males and 86 females with an average age of (78.76 +/- 7.32) years old ranging from 60 to 88; 45 cases were intertrochanteric fracture of femur, 103 cases were fracture of neck of femur; Singh index > or = IV in 74 cases, < IV in 74 cases;preoperative Harris score was 39.90 +/- 2.28. There were 146 cases in conventional treatment group,including 60 males and 86 females with an average age of (80.00 +/- 7.06) years old ranging from 66 to 96; 50 cases were intertrochanteric fracture of femur, 96 cases were fracture of neck of femur; Singh index > or = IV in 75 cases, < IV in 71 cases; preoperative Harris score was 40.10 +/- 2.81. Preoperative general situation,leaving bed time and hospital stay, the incidence of postoperative 12 weeks Singh index > or = IV and DPD/Cr value, Harris score at 12 months after operation and the incidence of fracture again of two groups were observed and compared.
RESULTSIn comprehensive treatment group 140 patients were followed up for 12 to 18 months with an anverage of 14.80 +/- 1.85. In conventional treatment group 132 patients were followed up for 12 to 14 months with an average of 12.75 +/- 0.79. There were no significant differences in age, gender, the classification of fracture, preoperative Harris hip score, preoperative Singh index > or = IV level and DPD/Cr value between the two groups (P > 0.05). Comprehensive treatment group had shorter leaving bed time and hospital stay, smaller postoperative 12 weeks DPD/Cr value and higher postoperative Harris score, higher incidence of postoperative 12 weeks Singh index > or = IV level, lower incidence of fracture again than conventional treatment group, there was statistically significant difference between two groups (P < 0.05).
CONCLUSIONFor the anti-osteoporosis effect, the comprehensive treatment group has more advantage than traditional treatment group in elderly hip fracture, which can further improve the elderly hip fracture treatment and provide the reference of evidence-based medicine cooperate with rehabilitation department.

OBJECTIVETo detect the expression level of interleukin 17 (IL-17) in the plasma and colonic mucosa of patients with ulcerative colitis (UC), and to explore the synergistic mechanism of qingchang huashi recipe (QHR) combined with Mesalazine.
METHODSRecruited were 24 mild or moderate UC patients of damp-heat inner accumulation syndrome (DHIAS). Their samples of intestinal tissues were histologically graded. They were assigned to the combination group and the Western medicine (WM) group, 12 in each group. Besides, another 12 healthy volunteers were recruited as the healthy control group. QHR combined Mesalazine were given to patients in the combination group, while those in the WM group took Mesalazine. The therapeutic course for all was 3 months. By the end of treatment the expression level of IL-17 in the plasma and colonic mucosa was detected using ELISA. The infiltration of IL-17 in the intestinal mucosal tissue was detected by immunohistochemical SP method.
RESULTSThe expression level of IL-17 in the plasma and colonic mucosa was significantly higher in UC patients than in healthy controls (P <0. 05). The higher the histological grading the higher the expression level. The expression level of IL-17 in plasma and colonic tissues decreased after treatment in the two treatment groups (P < 0.05). Besides, the expression level of IL-17 was lower in the combination group than in the WM group (P <0.05).
CONCLUSIONQHR combined Mesalazine could synergically enhance the effect and effectively inhibit intestinal inflammation through down-regulating the expression of IL-17.

ObjectiveTo investigate the feasibility of using the ratio of (Cho + Cr)/Cit derived by MRS to predict the differentiation grades of prostatic cancer and Gleason grading.Methods Five postoperative prostate specimens were spitted and layered according to the region of interest of MRS inspections.The correlation between the CC/C values of each region of interest in each layer and the Gleason scores of the corresponding pathological sections was analyzed.The optimum diagnostic cutoff value was determined by conducting the hypothesis test of the area below the ROC curve of the well and moderately differentiated groups and poorly differentiated ones on the basis of CC/C values with a Spearman test.Results A total of 90 regions with valid pathologic diagnosis were obtained,70 cancer-affected and 20 cancer-free.In MRS,a CC/C value above 0.86 was used as a criterion for defining a cancer-affected region As a result,65 cancer-affected regions and 25 cancer-free regions were identified,among which pathologic diagnosis confirmed 59 and 14,respectively.Spearman′s rank correlation analysis revealed that the CC/C values of the prostatic carcinoma had significant positive correlation with Gleason scores ( r =0.746,P =0.000).For the well and moderately differentiated groups,the hypothesis test about the cutoff value,which was obtained by calculating the area below the ROC curve,was of no statistical significance.For the poorly differentiated groups,the optimum cutoff value was defined as 0.948,and the sensitivity and specificity were 81.4% and 75.0%,respectively.It was also observed that the Gleason scores of the poorly differentiated endemic regions had positive correlation with the CC/C values ( r =0.605,P =0.000 ),suggesting that CC/C value was associated with the differentiation grade of the poorly differentiated prostatic cancer.When CC/C value was above 0.948,the poorly differentiated prostatic cancer was typically detected and Gleason score was often above 7.Conclusions CC/C values has positive correlation with Gleason scores.MRS may be used to predict the differentiation of prostate cancer.

Objective:Coherence analysis of the EEG is used to study the synchrony or coupling between cortical areas underlying the electrodes. However,the effects of intravenous anesthetics on EEG coherence have not been defined. Method: Forty patients were administered with intravenous thiopental (5mg/kg),propofol (2.5mg/kg ), ketamine(4mg/kg)or fentanyl(10?g/kg). The changes of coherences in total and in a given frequency band of the EEG(?.?.?.?) were measured with an AXON Systems Sentinel-4 Neurological monitor between two pair electrodes(Cz-F_7 vs Cz-F_8 and Cz-A_1 vs Cz-F_2). Result: The anesthetics had significantly different effects on the coherence by either increase or decrease. The variability of the coherences had no regular pattern,and no relationship to excitement or depression of the anesthetics and to potency of them. Conclusion:Each anesthetic above selectively depresses and excites generators of the EEG in quite different ways.
