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.

Objective:To explore the role of 6-CYANO-2,3-DIHYDROXY-7-NITROQUIN OXALINE (CNQX) in different types of synapse secretion.Methods:The spontaneous mEPSCs and eEPSCs at different extracellular concentrations of CNQX in cultured cortical or hippocampal neurons were recorded respectively.Results:The half inhibitory concentration (IC50) of CNQX in evoked neurotransmitter release was significantly higher than that of spontaneous release,indicating that the spontaneous neurotransmitter release was more sensitive to CNQX.No apparent difference was observed between cortical and hippocampal cells,suggesting that the blocking effect of CNQX was similar in different brain regions.Conclusion:CNQX might have differential regulating mechanisms between excitatory spontaneous and evoked neurotransmitter release,but without brain regions specificity.

AIM: To investigate the effects of lipid-induced insulin resistance on plasma resistin and ghrelin levels in awake rats. METHODS: A hyperinsulinaemic-euglycaemic clamp was established in awake chronically catheterized rats. Two groups of rats were studied either with a 4 h intraarterial infusion of lipid/heparin or saline. Insulin-mediated peripheral and hepatic glucose metabolism was assessed by insulin clamp combined with [~3H]-glucose infusion, and plasma resistin and ghrelin concentrations were examined before and after clamp with ELISA. RESULTS: During clamp, there was a significant increase in plasma free fatty acid (FFA, P

Objective This article is to discuss the best injection time after alcohol disinfection during the prophylactic immunization,provide theoretical support to guarantee the effect of disinfection in practical work,also guarantee the effect of vaccination especially for the vaccination of attenuated live vaccine at the same time reduce the side effect in disinfection.Methods Choosing the vaccination objects as experimental subject,each period contained 40 people,who were named as group A,B,C,D,E,with a total of 200 people.Using sterile cotton swab sampling and agar plate cultivation method,counting bacteria.Selecting vaccine either in liquid or in lyophilized form,counting the time of picking up the vaccine,dissolving it,suction and preparing the injector.Results After alcohol disinfection,there was 1 person and 1 colony growth in group A within 25 s.There were 1 person and 4 colonies growth in group B within 40 s.There were 3 persons and 3 to 12 colonies growth in group C within 60 s,there were 5 persons and 2 to 8 colonies growth in group D within 80 s,there were 8 persons and 3 to 13 colonies growth in group E within 100 s.The difference between group A,B,C and D was not statistically significant.All four groups mentioned above had significant difference compared with group E.The time of whole process for vaccine either in liquid or in lyophilized form was 1.05 min and 29 s.Conclusions During vaccine injection,especially injectable attenuated live vaccine,it is safe time to finish injecting within 25 to 45 seconds.In the operating process of vaccine inoculation,the freeting and drying dosage-form vaccine,the operation sequence must be set as dissolve the seedlings,disinfection,checkup information again and injections.For water dosage-form vaccine,the operation sequence is to disinfection,pulling out seedlings,checkup information again and injections.

Objective To observe the effects of dexamethasone (DEX) therapy on the clinical outcome and changes of lymphocyte subsets in children with mild and severe encephalitis.Methods Eighty-two children with mild and severe viral encephalitis were randomly divided into two groups: with DEX treatment (n=46) or without(n=36).The clinical efficacy was evaluated 3 weeks later, and the clinical manifestation were also observed. The changes of CD4~+,CD8~+ T lymphocyte percentage were determined by flow cytometry on admission and at 1 week,4 weeks after treatment.Another group of 20 cases was enrolled as control group.Results Compared with the control group,both the DEX treatment group and non-DEX treatment group showed a reduced CD4~+ lymphocyte count, an increased CD8~+ lymphocyte count(P

Objective To explore the changes of plasma somatostatin(SST) in children with septic shock.Methods The level of plasma SST in children with septic shock (test group,n=21) on an empty stomach at shock stage,blood pressure and heart rate recovery stage,recovery stage(at that time clinical symptoms and signs disappeared,infection indicators such as blood routine and CRP returned to normal,about 6-12 days after admission) were detected by competive radioimmunassay,the level of SST in healthy children(healthy control group,n=25) on an empty stomach on morning was detected,too.The levels of plasma SST between septic shock concbined with paralytic ileus group and without paralytic ileus group were compared.Results 1.Level of plasma SST of test group at shock stage[(44.60?16.83) ng/L]was significantly lower than that of control group[(123.15?6.57) ng/L](t=-12.16 P0.05).The level of plasma SST of children with paralytic ileus [(28.10?7.0) ng/L] was significantly lower than that of children without paralytic ileus [(56.98?9.44) ng/L](t=-7.70 P

Objective To investigate the histopathological and ultrastructural changes of corneal epithelium induced by erlotinib in mice.Methods Totally 30 6-8 weeks old male BALB/c mice were divided into three groups:Control group (n =12),experimental group (n =12),another 6 mice did nothing as the blank control.Experimental group used erlotinib eye drops and control group used PBS in both eyes,four times per day.At 1 day,7 days and 14 days after the intervention,corneal fluorescence staining (FL) was observed by slit lamp and graded.On the fourteenth day after the intervention,the eye balls of mice were taken,and the histopathological and ultrastructural changes of corneal epithelium and epithelial cells were observed by optical microscope and electron microscope,respectively.And protein of cornea was measured by Western Blot.Results Before the intervention,there was no significant difference in FL scores between the experimental group and control group (P ＞ 0.05).At 1 day,7 days and 14 days,FL score of experimental group was significantly higher than the groups of non-intervention,the difference was statistically significant (all P ＜ 0.05).While FL score of control group was not statistically significant before and after intervention (all P ＞ 0.05);Compared between two groups,there were statistical differences at 7 days,14 days in FL score (all P ＜ 0.05).In the experimental group,the histopathological changes of murine corneal epithelial cells had disorderly arrangement,increased layers of cells,and the inflammatory cells.Under electron microscope,the morphology of corneal epithelial surface cells was irregular and partially detached.The number of microvilli,desmosomes and hemidesmosomes were significantly decreased when compared to the control group.The expression of p-EGFR in experimental group was significantly less than that in control group,the difference was statistically significant (P ＜ 0.05).Conclusion Erlotinib can damage the tissue structure of corneal epithelium and ultrastructure of corneal epithelial cells in mice.And the mechanism is probably that erlotinib influence the corneal epithelium by inhibiting the EGFR activation.

The paper is aimed to identify SNP in Sarcandra glabra and Chloranthus spicatus, and authenticate S. glabra from Ch. spicatus and the mixture by using PCR amplification of specific alleles. SNPs in the ITS sequences of S. glabra and Ch. spicatus were found by ClustulX 2. 1 program and Bioedit software. Primers for authentic S. glabra and Ch. spicatus was designed according to the SNP site, and ITS sequence universal primers plus to the authentic primer to construct a multi-PCR reaction system, and then optimized the PCR reaction system. Five hundred and eighty band special for S. glabra and 470 bp band special for Ch. spicatus were found by using multi-PCR reaction. The multi-PCR reaction system could be applied to identify S. glabra and Ch. spicatus's leaves.
