Objective To analyse the clinical effect and mechanism of hirudin in the treatment of patients with lower limb venous thrombosis after fracture.Methods 56 patients who were diagnosed with lower limb venous thrombosis after fracture in our hospital were collected.All patients were randomly divided into experimental group (n:28) and control group (n:28).12h after fracture operation, patients in control group were treated with subcutaneous injection of low molecular weight heparin calcium, patients in experimental group were treated with Maixuekang capsule ( hirudin) orally on the basis of control group.Before and after the treatment, the plasma levels of thrombin antithrombin complex ( TAT) , thrombin activated fiber soluble inhibitor (TAFI), D-Dimer (D-D), fibrinogen (FIB), thrombin time (TT), prothrombin time (PT), activated partial thromboplastin time (APTT) and clinical effect were detected in all patients.Results After treatment, the total effective rate of experimental group ( 92.86%) was significantly higher than that of the control group ( 71.43%) ( P<0.05 );compared with control group, the plasma levels of TAT, TAFI were lower in the experimental group (P<0.05); the plasma levels of D-D, FIB were lower in the experimental group (P<0.05); the plasma levels of TT,PT,APTT were higher in the experimental group ( P<0.05 ) .Conclusion The hirudin could inhibit thrombin activation and coagulation function in fracture patients with lower limb venous thrombosis, decrease the plasma D-D and FIB levels for improving blood hypercoagulable state and preventing thrombosis,thus improve the clinical efficacy.

Objective To compare the masticatory efficiency of alveolar ridge restored by thermosetting resin full denture base and cast resin full denture base.Methods 30 patients with alveolar ridge were selected and divided intothe two groups by random number table and 15 cases in each group.Full denture with thermosetting resin base was worn in the first month in one group,and masticatory efficiency was measured.Then no false tooth was worn for a week,then full denture with cast resin base for a month,then masticatory efficiency was measured.In the other group,full denture with cast resin base was worn in the first month,and then masticatory efficiency was measured.Then no false tooth was worn for a week,then full denture with thermosetting resin base was worn for a month,then masticatory efficiency was measured.OD value as masticatory efficiency was measured by absorption spectrophotometry.Results The masticatory efficiency(OD value) of full denture with thermosetting resin base was (0.608 ± 0.124),and full denture with cast resin base was (0.885 ± 0.071).The masticatory efficiency of full denture with cast resin base was higher than that with thermosetting resin base (t =14.845,P ＜ 0.05).There was 13 cases of increased masticatory efficiency with hot coagulation resin base denture repair,the improved rate was 43.33 ％,while 24 cases with injection molding denture base denture repair,and the improved rate was 80.00％.The rate with injection molding denture base denture repair was higher than that with hot coagulation resin base denture repair(x2 =31.582,P ＜ 0.05).There was no significant adverse reaction in duration of test among all the patients.Conclusion The definition of full denture with cast resin base manufacture was high,and the masticatory efficiency of full denture with cast resin base is higher than that with thermosetting resin base,and the repair effects is better.It is worth of clinical application.

Purpose: To observe the long-term and recent clinical effect of needle-warming method plus functional training in the treatment of osteoarthritis of the knee joint. Methods:After 106 cases of the patients were divided into the needle-warming group and comprehensive group by the order of their first visit, the needle-warming group was treated by the needle-wanning method and the comprehensive group was treated by the needle-warming method plus functional training. After ten treatments, the clinical data in the two groups were evaluated upon Lequesne scale before and after the treatments. Three months later, follow-up survey was given to process the statistic management of the reoccurrence rate of the symptoms.Results: In the two groups after the treatment, the symptoms of the knee joint and daily life ability were obviously improved than the respective conditions before the treatment, and the integral decreased (P＜0.05), with no significant difference (P＞0.05) between the two groups. In the follow-up survey, there was a difference (P＜0.05) between the two groups in the positive rate of the recurrent symptoms. Conclusion: Certain therapeutic effect exists in the treatment of osteoarthritis of the knee joint by the needle-warming method. If functional training is combined,the therapeutic effect would be more stable, without easy reoccurrence.

Objective To investigate the effect of bed rest on acute nonspecific low back pain(ANLBP).Methods87 cases were randomly divided into bed rest group (42 cases) and free activity group (45 cases).The bed rest group would be proper activity indoor and step up activity outdoor after absolute in bed for a week.The free activity group would be prescribed free activity.At the same time,all of them received physiotherapy and non-steroidal anti-inflammatory drugs (NSAIDs).The visual analogous scale (VAS) were measured before and 2 weeks after treatment.The Roland-Morris disability questionnaire (RMDQ) were measured before and 2,6 weeks after treatment.ResultsThe difference of VAS and RMDQ scores between these 2 groups were not significant before treatment (P>0.05),but were significant 2 weeks after treatment(P<0.05).Further more,the difference of RMDQ scores between these 2 groups were not significant 6 weeks after treatment (P>0.05).ConclusionThe bed rest about patients could not promote,but delay the improvement of the pain and disability in the early period or later period recovery of ANLBP.

BACKGROUND:Acute exercise is believed to regulate appetite and influence feeding behaviors by controling the synthesis and secretion of gastrointestinal peptide hormones to regulate appetite and feeding behavior influence, but the smal sample size leads to widely different results.
OBJECTIVE:To clarify the effect of acute exercise on peptide YY levels in adults using Meta-analysis method. METHODS:A computer-based search of PubMed, Google Scholar, Sport Discus, Web of Knowledge and CNKI was performed for relevant articles published before January 2014. The literatures eligible were studied by evaluating the publication bias, checking the heterogeneity and analyzing the sensitivity by software of RevMan5.1.
RESULTS AND CONCLUSION:(1) There were a total of 188 participants in the 18 trials reported in 11 articles. The Meta-analysis results revealed a mean effect for acute exercise to increase peptide YY values (standardized mean difference=0.25, 95% confidence interval =0.05-0.46,P=0.01), and therefore, there was a significantly statistical difference in the peptide YY levels between the acute exercise group and control group (P< 0.05). Moreover, results from the sensitivity analysis showed no influences on the findings of Meta-analysis. (2) Five randomized controled trails in the three included articles were related to peptide YY (3-36). There was a maximal heterogeneity among these studies; therefore, a random-effect model was utilized. The result revealed a mean effect for acute exercise to increase peptide YY (3-36) values (standardized mean difference =1.80, 95% confidence interval =0.27-3.32,P=0.02). The findings from this meta-analysis show that acute exercise may influence appetite by increasing levels of peptide YY in adults.

Objective To investigate the correspond of microsatellite instability (MSI) on the prognosis and the effect of chemotherapy for colorectal cancer.Methods The publications about the MSI of colorectal cancer from January 2011 to October 2012 were searched.The Web of Knowledge and MEDLINE (PubMed) databases were used for searching English articles.The CNKI and WanFang databases were used for searching Chinese articles.Statistical analysis and graphics were performed with Comprehensive Meta Analysis V2 software.Results Thirty papers were included in this study.For the prognostic Meta-analysis,MSI-H was a protective factor for the overall survival of patients (OR =0.634,0.558-0.720; P ＜ 0.001).Simultaneously,MSI-H was a protective factor for the disease-free survival of patients (OR =0.571,0.479-0.681; P ＜ 0.001).After using of 5-Fu,the survival rate of MSS/MSI-L patients could be significantly elevated (OR =0.515,0.433-0.611; P ＜ 0.001).However,the survival rate of MSI-H patients did not increase significantly (0.631,0.302-1.318; P =0.220).Conclusions Both the overall survival and disease-free survival of MSI-H patients were significantly better than that of MSS/MSI-L patients.For MSS/MSI-L patients,the chemotherapy effect was remarkable.However,for MSI-H patients,there was no statistics difference between chemotherapy and no-chemotherapy group.

ObjectiveTo investigate the significance of hearing screening combined with gene screening for neonates with high-risk of hearing impairment.MethodsNeonates admitted to the Neonatal Department of Guangdong Women and Children Hospital between July 2013 and June 2014 were enrolled in this study. They were divided into high-risk group (with high-risk for hearing impairment) (n=3 129), and control group (n=5 106). Neonate hearing screening was carried out using otoacoustic emission and automated auditory brainstem response. Blood samples were collected using a standard protocol for detecting the mutations of four common deafness genes, includingGJB2,GJB3,SLC26A4 and mitochondrial 12s rRNA.Chi-square test was used to compare the differences of the pass rate of hearing screening and positive rate of gene mutations between the two groups.ResultsThe rates of failure on otoacoustic emission, automated auditory brainstem response or both in the high-risk group were 11.92% (373/3 129), 10.32% (323/3 129) and 4.83% (151/3 129), respectively, higher than those in the control group [5.03%(257/5 106), 6.56%(335/5 106) and 2.02% (103/5 106)] (χ2=130.265, 37.354 and 51.196, allP=0.000). In the high-risk group, the overall positive rate of gene mutations was 5.63% (176/3 129), and theGJB2 andSLC26A4 gene mutation rates were 3.04% (95/3 129) and 2.40% (75/3 129)], all higher than the control group [3.15% (161/5 106), 2.04% (104/5 106) and 1.06% (54/5106)] (χ2=30.301, 8.216 and 22.517, allP<0.01). But the mitochondria 12S rRNA gene andGJB3 gene mutation rates were the same in high-risk group and control group [0.19% (6/3 129) vs 0.06% (3/5 106); 0.03% (1/3 129) vs 0.00%(0/5 106), bothP>0.05]. The rates of failure on otoacoustic emission and automated auditory brainstem response of the neonates with deafness gene mutations were 9.50% (32/337) and 10.39% (35/337), respectively, higher than the neonates without [1.14% (90/7 898) and 1.29% (102/7 898)] (χ2=154.621 and 163.399, both P=0.000).ConclusionCombined hearing screening is of clinical significance for neonates with high-risk of hearing impairment.
