OBJECTIVETo explore methods and clinical effects of composite external fixtor in treating adult patients with unstable middle 1/3 of clavicular fractures.

METHODSFrom March 2008 to March 2011,36 patients with unstable middle 1/3 of clavicular fractures were treated with composite external fixtor. There were 24 males and 12 females, aged from 18 to 55 years old with an average of 43 years old. Twenty cases on the left side and 16 cases on the right side. Time from injury to operation was 2 to 6 days (averaged 3.5 days). According to Robinson classification, there were 7 cases with type 2A2, 18 cases with type 2B1, and 11 cases with type 2B2. No vessels and nerve damage occurred before opreation. The clinical effects were evaluated according to Neer scoring.

RESULTSAll cases were followed up from 6 to 12 months with an average of 8 months. The mean Neer score was 88.3 +/- 6.2, which included pain 31.6 +/- 3.2, functional score 25.7 +/- 2.2, range of motion score 21.1 +/- 1.7, and anatomy score 8.8 +/- 0.8. There were 22 cases in excellent, good in 13, fair in 1. Two cases occurred pin tract infection.

CONCLUSIONComposite external fixtor is an optional method in treating unstable middle 1/3 of clavicular fracture, and can obtain a good clinical effects.

OBJECTIVETo understand the real world, the use of ultra- treatment Shuxuetong injection on liver and kidney functions are affected.

METHODThe 18 hospitals of the country's HIS data sources from which to choose to use Shuxuetong injection, between the ages of 18 to 80 years, using Shuxuetong and the first seven days after discontinuation of at least 7 days has once aspartate aminotransferase or alanine aminotransferase, or creatinine or blood urea nitrogen were measured value as a research object, the number of days of medication is based on more than 14 days, divided into treatment group and the normal course of super-group to reach the normal range of physical and chemical indicators 200% of the upper limit is defined as abnormal. Using the propensity score method, balance the known confounding factors, differences in the occurrence of abnormal renal function and compared between the two groups.

RESULTThe treatment group and the normal course of super-group, resulting in alanine aminotransferase, aspartate aminotransferase, creatinine, urea nitrogen equally likely targets abnormal changes, no statistically significant difference.

CONCLUSIONBased on the available data did not find "super treatment using Shuxuetong damage the liver and kidney function" the situation, but the clinical disease lasts insist on the principle can not be arbitrarily extended treatment to prevent long-term medication.

OBJECTIVETo understand the real world Shuxuetong injection suspicious allergic factors.

METHODNational 18 hospitals of the hospital information system using Shuxuetong data, using design methods retrospective nested case-control, and contrast using Shuxuetong after the occurrence of allergic reactions in patients with non-allergic patients differences in age, gender, admission illness, allergies, etc.

RESULTBased on available data, indicate suspicious allergies affect Shuxuetong factors may be hospitalized illness, solvent, single dose, concomitant medications.

CONCLUSIONWhen using Shuxuetong for critically ill patients should use caution and pay attention to solvents, dose, combination therapy of choice clinically. Conclusions of this study need further study to be verified.

OBJECTIVETo evaluate the effectiveness of manual therapy and traction for lumbar disc herniation and analyze the current status of this kind of randomized clinical trial (RCT).

METHODSDatabase of CNKI, VIP, WANFANG, PubMed and OVID were searched. Some relevant journals were manually retrieved. A total of 2 874 literatures on manual therapy and traction for lumbar disc herniation were collected, of which 17 articles met the inclusion criteria. The Jadad score scale was used to evaluate the quality,and RevMan5.0 was used for meta-analysis of literatures.

RESULTSThe results of the meta-analysis of all trials involved were as followed:the combined effect of the effective rate was RR = 1.10, 95% CI [1.06, 1.14], the combined effect of the cure rate was RR = 1.36, 95% CI [1.21,1.52], the combined effect of the VAS was RR = 1.37, 95% CI [1.28, 1.45], the combined effect of the JOA was RR = 4.75, 95% CI [4.40, 5.09].

CONCLUSIONThe overall quality of the current RCT researches about manual therapy for lumbar disc herniation was lower,and did not support the conclusion that manual therapy was more effective than traction for lumbar disc herniation.

OBJECTIVETo investigate the effect of baicalein on the gap junction intercellular communication (GJIC) in the TM4 Sertoli cells of the mouse testis and its related mechanism.

METHODSWe measured the cytotoxicity of different concentrations of baicalein on the TM4 Sertoli cells in the mouse testis by MTT, detected the fluorescence transfer of the TM4 Sertoli cells by parachute assay, and determined the expression of the protein connexin 43 ( Cx43) in the baicalein-treated cells by Western blot and immunofluorescence assay.

RESULTSBaicalein produced no obvious cytotoxicity on the TM4 Sertoli cells at the concentration below 60 µmol/L but significantly increased their GJIC at 0-20 µmol/L (P < 0.01). Western blot and immunofluorescence assay showed that 0-20 µmol/L baicalein remarkably elevated the expression of Cx43 in the TM4 cells (P < 0.01) and on the membrane of the TM4 cells.

CONCLUSIONBaicalein at the concentration of 0-20 µmol/L can significantly enhance GJIC in mouse TM4 Sertoli cells by increasing the expression of the Cx43 protein.

OBJECTIVETo discuss the best strategy in tympanoplasty for cholesteatoma in pediatric patient. Both intact canal wall mastoidectomy with tympanoplasty (ICW) and canal wall down mastoidectomy with tympanoplasty (CWD) were the basic technique for cholesteatoma in pediatric patient. The outcomes of ICW and CWD as comparisons of different surgical technique were assessed.

METHODSA retrospective analysis of all cases of pediatric primary acquired cholesteatoma aged 4-14 years old between April, 1997 and October, 2003 was conducted. The follow-up information was completed. Forty-two patients (45 ears) were treated and followed from 1 to 7 years [ the average is (3.6 +/- 2. 6) years].

RESULTSICW was the primary surgical treatment in 20 patients (20 ears) initially, the recidivism rate was 30% ( 6/20), the achieved rate of pure-tone threshold average (PTA) was 77% (13/17); Twenty-five (two) patients (45 ears) underwent CWD, the recidivism rate was 4% (1/25), the achieved rate of PTA was 72% (18/25).

CONCLUSIONSICW had the advantage which could preserve the physical structure of the external acoustic meatus and had more profits for the treatment of cholesteatoma in pediatric patients, but it should be done for planned second stage surgery as a routine method that could get over the defect of recrudescence . If the function of eustachian tube was still not normal when planned second stage surgery operation was done, the CWD was suggested instead.
