OBJECTIVETo assess the efficacy and safety of mouse nerve growth factor (mNGF) in patients with peripheral nerve injury.

METHODSSuch electronic database as Cochrane Library (Issue 1, 2011), Medline (1950-2011), Embase (1980-2011), National Knowledge Infrastructure (1979-2011) were searched and meanwhile relevant journals such as Chinese Journal of Orthopaedics, Chinese Journal of Microsurgery, Chinese Journal of Neurosurgery, etc were searched as well to collect all randomized controlled trials and quasi-randomi- zed controlled trials of mNGF on patients with peripheral nerve injury. The quality of included studies was assessed according to the criteria recommended by the Cochrane Handbook for Systematic Reviews of Interventions and the data were extracted by two reviewers independently. Meta-analysis was conducted by RevMan 5.1 software.

RESULTSForty-one studies involving 3 304 patients with peripheral nerve injury were included. The results of meta-analysis showed that: (1) the total effective rate of peripheral nerve injury treatment in mNGF group was ob- viously higher than that in control group (OR equal to 6.36, 95% CI 4.96-8.15, P less than 0.01); (2) the scores of activities of daily living (ADL) in mNGF group was significantly higher than that in control group (weighted mean difference equal to 1.97, 95% CI 1.33-2.61, P less than 0.01); (3) the incidence of adverse reaction in mNGF group was higher than that in control group, (OR equal to 1.66, 95% CI 1.61-2.38, P equal to 0.006), but the adverse effects were mild, which could be relieved without specific treatment or just given symptomatic treatment, and disappeared at the end of treatment.

CONCLUSIONSThe mNGF therapy is effective for peripheral nerve injury. It can obviously improve patient's ADL. Though the incidence of adverse reaction in mNGF treatment group is higher than that in control group, this does not influence the treatment outcomes.

OBJECTIVETo evaluate the local recurrence and 5-year survival of proximal fibular osteosarcoma.

METHODSFrom October 1997 to July 2005, 12 patients with proximal fibular osteosarcoma were treated. There were 9 males and 3 females. The mean age at diagnosis was 16 (9-23) years old. Histopathological diagnosis were obtained by trut-cut biopsy, Enneking surgical stages of 12 lesions were as follows: 11 grade II B and 1 grade III. Induction chemotherapy was applied to all patients except one who left the hospital after the biopsy. Of 11 patients, 8 were performed Malawer type I resection, and 3 type II. All patients continued to get postoperative chemotherapy.

RESULTSRegular follow-up was applied. Only 1 patient was found local recurrence one year after operation and received re-resection, the others did not. Four patients died of lung metastases, including the one who did not get treated, one stage III and two II B patients. The range of follow up was 6 to 117 months. The evaluated 5 year disease-free survival of 11 patients who got treated was 72.7% by using Kaplan Meier survival analysis.

CONCLUSIONSThe local recurrence is low, and 5 year disease-free survival is acceptable, in accordance with present point that marginal resection may not impact survival for fibular osteosarcoma. No knee instability is found in this group after great care is taken for proper reconstruction of lateral collateral ligament and reinsertion of biceps femoris tendon on the lateral condyle of tibia.

Objective To compare the therapeutic effect of the combination of ~(99m)Tc-methnetium methylene diphosphunate and colloidal chromic,phosphate ~(32)p with the monotherapies in rats with adjuvant arthritis(AA).Methods In this study,50 Sprague-Dawley rats were randomly divided into five groups with 10 rats in each:normal control group(arthritis induced and treated with the same volume of normal saline via the same administration route),AA control group(arthritis induced with adjuvant and treated with normal sa- line),~(32)p colloid group(arthritis induced with adjuvant and treated with single intra-articular injection of col- luidal chromic phosphate ~(32)p 0.74 MBq and intra-peritoneal injection of normal saline every other clay),~(99m)Tc- MDP group(arthritis induced with adjuvant and treated with intra-peritoneal injection of ~(99m)Tc-MDP 2.5?10~(-3)?g/kg every other day and single intra-articular injection of normal saline),combination group(arthritis in- duced with adjuvant and treated with the combination of the two drugs).The diameter of the left hind ankle, serum levels of turnout necrosis factor(TNF)and interleukin-1?(IL-1?),and the pathological changes of an- kle joints were tested at different time points.Results The diameter of the left hind ankle at week 4 was smaller in the combination group than that of the ~(32)p colloid treatment alone group [(7.11?0.34)mm vs(7.57?0.29)mm,P

Objective To know the prevalence of chronic obstructive pulmonary disease(COPD) in patients with obstructive sleep apnea-hypopnea syndrome(OSAHS) in Kunming Yunnan Province, and the clinical symptom of OS.Methods Retrospective study of 4 636 cases of patients with snoring, excluding COPD in addition to chronic respiratory disease and assess the patient`s condition.The test included AHI, BMI, Epworth sleepiness scale, lung function.The index of OS was confirmed by AHI>5 times/h and FEV1/FVC<70%.Results During the period of 2006 to 2012, he prevalence of COPD in patients with OSAHS was 10.1% [95% confidence interval (CI) 9.1%-11.1%] in Kunming Yunnan Province.And male`s OS prevalence rate is higher than the female(male 10.2%;female 9.7%).The OS patients` average age was 56.9±14.1, the mean AHI was (47.46±26.79) times/h, and the average FEV1/FVC was 60.09%±23.57%.Polysomnographyresults show that patients suffered obvious hypoxiaat night in both OSAHS group and OS group, but it was more significant in OS group.Pulmonary function test showed that OS patients have more serious chronic obstructive pulmonary disease.Conclusions The prevalence of COPD in OSAHS patients was high in Kunming, Yunnan Province, and the prevalence rate in old group reached more than 24%.In addition, the sympotms of patients with OS were more severe than those with only OSAHS or COPD in lung function and hyoxemia.

Objective To evaluate the conventional ultrasound (US) and contrast-enhanced ultrasound (CEUS) in diagnosis of splenic trauma including its grading diagnosis. Methods US and CEUS in 42 patients with splenic trauma confirmed by CT and/or operation were performed during 9.2004-10.2007. All the data were compared and analyzed retrospectively. Results Of 42 patients with splenic trauma, 28 cases were detected and 14 cases were missed on US examination, whereas, 40 cases were detected and only 2 mild cases were missed on CEUS examination. The detection rate of lesions with CEUS was significantly higher than that of US (P<0.001) . Ten cases in grading the injury were underestimated by US, however, none of them were underestimated by CEUS. CEUS had good concordance with CT and/or operation in grading diagnosis of 42 cases except two mild cases. Conclusions CEUS has very good concordance with CT and/or operation in detecting injury and grading the splenic trauma compared with conventional US. CEUS as a new imaging technology has made great advance of ultrasoongraphy in evaluation of splenic trauma including injury grading,and it is very useful in clinical application.

Objective To investigate the molecular epidemiological characteristics of Staphylococcus aureus associated with bloodstream infection in hospital. Methods 47 Staphylococcus aureus strains isolated from bloodstream in PLA General Hospital were collected from January 2006 to December 2008. Susceptibility of the strains to 11 antimicrobial agents was detected and DNA homology of them was analyzed with Rep-based DiversiLab~(TM) Microbial Typing System. Panton-Valentine leukocidin (PVL)gene was determined by PCR. For methicillin-resistant Staphylococcus aureus (MRSA) strains,the genotypes of SCCmec were determined and ST239 clone was screened with multiplex PCR. Multilocus sequence typing (MLST) was used to determine the STs of the selected isolates. Results In the 47 Staphylococcus aureus isolated from blood,methicillin-resistant strains accounted for 51.1%,all belonged to SCCmec Ⅲ type,with only 2 pvl gene positive strains identified. 12 different patterns (A-L) were found among 47 strains with Rep-PCR. All MRSA strains clustered in the A and B subtypes. Conclusion Most MRSA strains isolated from blood in PLA General Hospital belonged to ST239-MRSA-SCCmec Ⅲ clone. DiversiLab~(TM) Microbial Typing System could provide a rapid and effective method to investigate the molecular epidemiological characteristics of Staphylococcus aureus in the hospital settings.

This study aims to investigate the change of plasma concentration of digoxin (DIG) in rats with ovariectomy. Twelve female SD rats were randomly assigned into ovariectomized group and sham group (n = 6). All rats plasma was collected after a single dose of 2 mg x kg(-1) DIG administrated orally, serum DIG concentration was determined by LC-MS/MS. The level of P-gp in the intestinal was analyzed by Western blotting. Pharmacokinetic calculations were performed on each individual using DAS 2.0 practical pharmacokinetic software. Compared with the sham group, C(max) of ovariectomized group decreased significantly (P < 0.01). There was no significant difference of AUC(0-t), and the level of P-gp was elevated in ovariectomized group. It was found that C(max) of DIG was significantly reduced after ovariectomy, and the change was associated with the decreased level of estrogen, which contributes to the increased level of P-gp.
