Objective This study aims to develop a lottery addiction scale (LAS) for Chinese welfare lot-tery buyers. Methods A scale made by authors was applied to 8238 welfare lottery buyers from 31 provinces,one sample of 4071 cases for exploratory factor analysis (EFA) ,and the other 4167 cases for confirmatory factor analy-sis (CFA). Results Through EFA, the scale consisted 10 items established, and it was divided into two factors: functional impairment and emotional dependency. These two factors could explain 45.5% of total variance, The scale was confirmed by CFA (X2/df=13.34 ;IFI=0.96 ;CFI=0.96 ;NFI=0.96 ;RSMEA = 0.054). The internal consistencies of the scale answered to the basic statistic criterion (r=0.59～0.74). Criteria validity shown by higher LAS scores in high expending group than low expending group was also satisfying. Conclusion The LAS has good psychometric features and could be applied to Chinese lottery buyers.

Objective To investigate the feasibility of biomedical fibrin glue in laparoscopic treatment of peptic ulcer perforation.Methods A total of 126 patients with peptic ulcer perforation were randomly divided into two groups (63 in each group).Biomedical fibrin glue was used in treatment group,and routine treatment was used in control group.The total volume of drainage after operation,rate of intestnial fistula and adhesions,allergy reaction,time of drainage tube removal,and average hospotal stay time were observed in both groups.Results There was no allergic reaction in treatment group.Total volume of drainage in treatment group was(65.3?7.5)mL,and (110.2?9.6)mL in control group,with a significant difference between the two groups(P

0.05).Conclusion Acupuncture has an effect on I/O curve amplitude of EPSP and PS,and on LTP induction of PS of dentate gyrus(DG) in rats after cerebral ischemia.However,the difference of effect of acupuncture at different doses on LTP induction is insignificant.

Purpose:To investigate the value of susceptibility-weighted imaging(SWI)in evaluating the histopathologic grade of cerebral astrocytomas.Materials and Methods: 18 patients with histologically proven cerebral astrocytomas,including 7 diffuse astrocytomas,3 ana-plastic astrocytomas and 8 glioblastomas before treatment were involved in this study.The features on SWI were analyzed in 18 cerebral astrocytomas.Results: The veins in the tumors were not detected in 7 diffuse astrocytomas.Slight edema round tumors appeared in all the diffuse astrocytomas.Plenty veins in the tumors and severe edema round the tumors appeared in 3 anaplastic astrocytomas and 8 glioblastomas.The hemorrhagic foci were detected in 1 anaplastic astrocytomas and 6 glioblastomas.The edema round the tumors were moderate or severe in all the anaplastic astrocytomas or glioblastomas.Conclusions: Susceptibility-weighted imaging can provide the informations about blood supply,hemorrhagic focus and edema round the tumors.SWI is very useful for preoperative evaluation of the histopathologic grade of cerebral astrocytomas,especially for evaluation of high or low grade astrocytomas.

Objective To summarize the clinical experience of laparoscopic total extraperitoneal hernia repair (TEP) combined with varicocele ligation for treating inguinal hernia combining with varicocele (VC).Methods Clinical data of 22 patients of inguinal hernia complicated with varicocele from April 2011 to April 2016 was retrospectively analyzed. All the patients were treated by TEP combined with high ligation of spermatic vein. Then monitor and analyzed clinical indexes intra- and postoperatively.Results The mean operation time was (55.0 ± 9.0) min, mean intraoperative blood loss was (5.5 ± 2.8) ml, all patients can eat after anesthesia recovery and off-bed after staying in bed for 24 hours; all patients don’t need postoperative analgesia; only 1 case suffered seroma postoperative; the average hospitalization time was (4.7 ± 0.9) days; postoperative follow-up of 1 to 5 year without recurrence.Conclusion The surgical effect of TEP combined with varicocele ligation is confirmed with less invasive, faster postoperative recovery and achieving an obvious social and economical effect, it is worthy of deserving further clinical application.

OBJECTIVETo assess the diagnostic efficacy of contrast-enhanced CT in diagnosing mandibular invasion of oral cancers.

METHODSPubMed, Excerpta Medica Database (EMBASE), the European Grey Literature Database, Chinese Biomedical Literature Database (CBM), and CQVIP were searched electronically on January 03, 2014. Hand-searching was also performed on 19 relevant Chinese journals. The methodological quality assessment, as suggested in Cochrane Handbook, and the data extraction of the studies included were performed by two reviewers in duplicate. Meta-analysis was conducted using the Meta Disc 1.4 software.

RESULTSFourteen studies that involved 642 participants were included. Among the seven prospective studies, one had a low bias risk and the rest had unclear bias risks. When mandibular invasion was diagnosed the Meta-analysis results showed that the pooled sensitivity (SEN) was 0.718 [95% confidence interval (CI), 0.665-0.767], the pooled specificity (SPE) was 0.909 (95% CI, 0.872-0.938), the area under curve (AUC) was 0.906 1, and the Q* was 0.837 8. When mandibular medullary invasion was diagnosed, the SEN was 0.787 (0.643-0.893), the SPE was 0.904 (0.790-0.968), the AUC was 0.949 6, and the Q* was 0.890 0. The Meta-regression results showed that the smaller slide thickness had a higher diagnosis efficacy.

CONCLUSIONCT showed a high efficacy in diagnosing mandibular or medullary invasion caused by oral cancers. With a high SPE, contrast-enhanced CT can confirm the clinical diagnosis of bone invasion effectively. In addition, selecting a smaller slide thickness CT can increase diagnosis efficacy.

Objective To investigate the effect of thrombelastography ( TEG ) monitoring on anticoagulation therapy in deep vein thrombosis ( DVT ) in the perioperative period of arthroplasty replacement through dynamic detecting of TEG.Methods 60 patients under went total knee arthroplasty ( TKA) were selected as the patient group from 2011 to 2013, Including 22 men and, 38 women, aging from 50 to 74 years old.These patients were divided into low molecular weight heparin ( LMWH ) group and rivaroxaban group according to random number table.Each group had 30 cases.Patients in both were all given routine dose anticoagulant drugs to prevent DVT.Other treatment were the same as conventional therapy for both group patients.Meannhile, 42 health examination participants were selected as the control group, 24 men and 18 women, aging from 45 to 75 years old.The parameters of TEG were measured by TEG@5000 thromboelastograph hemostasis system ( American Haemoscope Corporation).DVT was diagnosed by LOGIQ 7 color Doppler ultrasonic diagnostic apparatus of American GE Corporation. Data were analyzed by SPSS17.0.The predictive value of TEG on DVT was evaluated by receiver operating characteristic cure (ROC),sensitivity,specificity,positive predictive value (PPV) and negative predictive value (NPV). Results Abnormal detection rates of Angle,MA,CI in rivaroxaban group(36.7%,46.7%,36.7%) were higher than LMWH group ( 10.0%, 20.0%, 13.3%) , and the differences between both groups all had statistical significance between both group(χ2 =5.963,P=0.015;χ2 =4.800,P=0.028;χ2 =4.356,P=0.037).CI , MA and Angle had better clinical diagnostic value on DVT.Their sensitivity was 75.0%, 75.0% and 62.5%, specificity respectively was 80.8%, 76.9%and 78.8%respectively.MA=68.35 mm
could be the best clinical diagnosis of critical point on DVT at anticoagulation treatment endpoint.Conclusion TEG can monitor coagulation state of TKA patients, TEG′R can evaluate the safety and effectiveness of anticoagulation therapy on DVT.(Chin J Lab Med, 2015, 38:333-336)

High altitude polycythemia (HAPC) had become one of the main common chronic diseases, which had seriously threatened the health of Plateau people. In the Tibetan medicine classic bookSi-Bu Yi-Dian, there were recordings on HAPC treatment methods and medications, which had the unique advantages of identified therapeutic effect with little side effect. This article analyzed Tibetan medicine in the prevention and treatment of HAPC from aspects such as etiology and pathogenesis, clinical treatment advantages and modern innovation study. Questions were also raised on lacking of standardization on HAPC clinical effectiveness, as well as Tibetan medicine compound material basis and action mechanisms were unclear. It was proposed that based on the inheritance of Tibetan medicine theoretical basis and clinical therapeutic effect, the Tibetan medicine original thinking should be combined with modern science and technology, in order to strengthen the analysis of ancient literature collection in HAPC treatment and data mining in medication experiences. The clinical treatment standards and medication plan should be standardized. Methods of systems biology, such as metabolomics, can be used in the further study of the scientific connotation of HAPC treatment by Tibetan medicine.

Objective To investigate the predictive value and clinical significance of dynamic monitoring of thromboelas?tography (TEG) and D?dimer on anticoagulation therapy concurrenting DVT in the perioperative period of arthroplasty replace?ment. Methods All of 60 patients of total knee arthroplasty (TKA) were selected as patient group from 2011 to 2013. They were divided into low molecular weight heparin (LMWH) group and rivaroxaban group according to random number table. LM?WH group was given LMWH (xi fu quan) 4250 IUAXa 12 h after knee replacement, im, qd for 7 days, then rivaroxaban 10 mg, qd for 7 days. Rivaroxaban group was given rivaroxaban 10 mg 6 h after knee replacement, qd for 14 days. Meanwhile, 42 health examination participants were selected as control group. The parameters of TEG were detected by TEG 5000 thrombo?elastograph hemostasis system (American Haemoscope Corporation). Results D?dimer levels of postoperative before anticoagu?lation therapy were highest and there was statistical difference, while other parameters had no statistical difference. Intra?group comparison:the levels of R, K, Alpha, CI of TEG and D?D in LMWH group and the levels of Alpha, MA, CI of TEG and D?D in ri?varoxaban group had statistical difference, while other parameters' levels showed no statistical difference. At anticoagulation treat?ment endpoint, DVT occurred in 8 cases with an incidence of 13.3%(8/60). 7 cases were intramuscular vein thrombosis, and 1 case was popliteal vein thrombosis. The levels of Alpha, MA, CI of TEG and D?D in DVT group were higher than no DVT group, and there was statistical difference. TEG's CI, MA, Alpha and D?dimer had better clinical diagnostic value on DVT, whose area un?der receiver operating characteristic cure (ROC) respectively was 0.746, 0.733, 0.707 and 0.644, with sensitivity of 75%, 75%, 62.5%and 62.5%, specificity of 80.8%, 76.9%, 78.8%and 71.1%, positive predictive value of 37.5%, 33.3%, 31.3%and 25.0%, and negative predictive value of 95.4%, 95.2%, 93.2%and 93.1%. MA=68.35 mm was the best clinical diagnosis of critical point on DVT at anticoagulation treatment endpoint. Conclusion CI, MA, Alpha of TEG are better than D?dimer in predicting the inci?dence of DVT in the perioperative period of orthopaedics major operation. If these indexes are detected, the diagnosis value ’s ac?curacy of DVT will be improved.
