Objective To investigate surgical technique and clinical efficacy of Sky bone ex- pander kyphoplasty in the treatment of osteoporotic vertebral body compression fractures.Methods Eighteen cases with osteoporotic vertebral body compression fractures were treated with Sky bone expander kyphoplasty from August 2004 to November 2005.Under the local anesthesia,3.5-5ml of bone cements were injected into each pathologic vertebral body through unipedicle approach after reduction procedure was done with Sky bone expander.Results The postoperative follow-up ranged from 3 to 11 months, with an average of 4.5 months.Back pain was effectively relieved after the operation in all cases.No complications occurred.Conclusion The Sky bone expander kyphoplasty has the advantages of safe- ty,easy operation,minimal invasion,effective restoration of the vertebral body height and fast relief of pain.

OBJECTIVETo study the clinical efficacy of Fuzheng Jiedu Granule (FJG) in coronary heart disease (CHD) patients in long term contact with nickel (Ni) and its effect on electrocardiogram (ECG) and cardial enzymes.

METHODSSixty cases were randomly assigned to two groups with 30 cases in each group, the treatment group treated with FJG plus Western medicine and the control group given Western medicine alone. The therapeutic course in both groups was 4 weeks. Another 15 healthy subjects from the same region were taken as the healthy control. Changes of clinical symptoms and ECG were observed, and the serum levels of creatine kinase (CK), lactic acid (LD), lactic dehydrogenase (LDH), Na+-K+-ATPase, Ca2+-ATPase and Ni were detected before and after treatment.

RESULTSThe ameliorative effects on symptoms, signs and ECG in the treatment group were superior to those in the control group (P<0.05). Compared with healthy subjects, the serum levels of CK, LD, LDH and Ni were higher and the serum levels of Na+-K+-ATPase and Ca2+-ATPase were lower in patients before treatment; after treatment, the decrease of serum CK, LD, LDH and Ni levels and increase of serum Na+-K+-ATPase and Ca2+-ATPase were more significant in the treatment group than those in the control group (P<0.05 or P<0.01).

CONCLUSIONFJG can decrease the serum Ni level, recover the activity of myocardial enzymes, thus to improve symptoms and abnormal ECG figures in CHD patients.

Objective The purpose of this study was to investigate the expression of human mitochondrial transcription termi-nation factor-3 ( hMTERF3) in non-small cell lung cancer ( NSCLS) and to analyze its clinicopathological significance. Methods The paraffin block samples used in this study included 65 cases of NSCLC and 32 cases of normal alveolar epithelial tissues. We determined the expressions of hMTERF3 in NSCLC and normal alveolar epithelial tis-sues by immunohistochemistry, calculate the survival rate using the Kaplan-Meier method, and analyzed the risk factors affecting the prognosis of NSCLC using the Cox Proportional Hazard Model. Results In the 65 cases of NSCLC, 31 ( 47. 69%) showed positive expression of hMTERF3. The total survival time was significantly shor-ter in the patients with a high than in those with a low hMTERF3 ex-pression ([30.39±3.35] vs [57.61±7.12] mo, P<0.05). The riskfactors affecting the prognosis of NSCLC included positive expression of hMTERF3 (HR=3.302, 95% CI:1.598-6.905) and lymph node metastasis (HR=4.052, 95% CI: 1.212-12.398). Conclusion hMTERF3 is overexpressed in NSCLC. Highly expressed hMTERF3 and lymph node metastasis reduce the survival time of NSCLC patients, suggesting that hMTERF3 may be a potential bio-marker for the prognosis of NSCLC.

Objective To compare the different surveillance system evaluation guidelines proposed by US Center for Disease Control and Prevention (CDC) and WHO, so as to develop an evaluation strategy suitable for communicable disease surveillance systems in China. Methods Systematic collection and review on the guidelines that were proposed by US CDC and WHO.Situation analysis together with feasibility analysis were linked to the analysis of evaluation strategy used in China. Results US CDC guidelines were more appropriate for evaluating those single or appropriate for evaluating the multi-system or complicated system which focusing on data related to moment to start to evaluate the functions. Conclusion More flexible and comprehensive strategy based on national conditions is needed when constitute the national communicable disease surveillance evaluation guidelines. The multi-step strategy described in this article could be used as reference.

OBJECTIVE: Based on a retrospective analysis of the drunk driving cases, to explore the drunk drivers' personnel composition, occurrence time and psychology. METHODS: As a result of punishment of the drunk driving by criminal law for one year from May 1st, 2011 to April 30th, 2012, 91 drunk driving cases were statistically analyzed the easy-happening time of drunk driving, the drunk drivers' age, gender, occupational characteristics, domicile and psychological factors. RESULTS: In 97 drunk driving cases, 26-40 years old, non-local domiciled and non-professional male drivers were prone to drunk driving at night from 22:00 to 5:00. CONCLUSION The behavior of drunk driving is relevant to time, age, genders and occupation. The psychological characteristics of most drivers are fluky, making-life-easy, competitive and peacockish.

BACKGROUNDTo avoid the irritation of tendons and soft tissues as well as hardware-related problems, we designed an intramedullary fixation with bioabsorbable rods for the treatment of the metacarpal shaft fractures.

METHODSFive patients with nine shaft fractures of the fourth and fifth metacarpi were treated with intramedullary absorbable implants and followed up with an average of 4.2 months postoperatively.

RESULTSAt final follow-up, all patients achieved fracture union with no signs of inflammatory or subcutaneous effusion. There was no shortening, angulatory, or rotatory deformity. There was almost full active extension range of motion (ROM) of the metacarpophalangeal joints while the active flexion ROM of these joints was 80.7 ± 9.6°. Compared with the contralateral hand, the grip strength of the injured hand was 94.0 ± 9.6%. X-rays showed that the arch of the second to fifth metacarpal heads was smooth. There were no intramedullary lytic changes and soft tissue swellings.

CONCLUSIONThe intramedullary absorbable implants are a safe, simple, and practical treatment for fourth and fifth metacarpal fractures with good early clinical outcomes and no significant complications.

Chronic hepatitis B virus ( HBV) infection is a principal risk factor for liver cirrhosis and hepatocellular carcinoma in China , representing one of the major public health problems .Horizontal trans-mission of HBV in vaccinated children was greatly reduced due to widespread HBV vaccination in mainland China, which had limited effects on vertical transmission .Thus, vertical transmission became one of the main causes of HBV chronic infection .High HBV load (≥10 6 copies/mL ) and hepatitis B e antigen ( HBeAg )-positivity in maternal peripheral blood were independent risk factors for HBV intrauterine infection .Compared to HBV infection in early childhood and in adult , intrauterine HBV infection was more prone to developing chronic infection .To decrease vertical transmission of HBV , we recommend that young pregnant women with sero-positive for HBeAg and high serum HBV DNA level should receive antiviral treatment with nucleotide analogues since the 28 th gestation weeks .For newborns born to HBeAg-positive mother , hepatitis B immunoglobulin ( HBIG ) injection should be administrated in combination with HBV vaccination .
