Objective:To discuss the clinical efficacy of minimally invasive locking plate and the traditional open reduction with internal fixation in the treatment of proximal humerus fractures.Methods:89 cases of patients with proximal humeral fractures were selected and divided into two groups according to different surgical methods.The observation group (45 cases) was given minimally invasive locking plate,while the control group (44 cases) was treated with the traditional open reduction and internal fixation.The operation time,hospitalization time,fracture healing time,intraoperative blood loss,Neer score and Constant-Murley score at 1 month after postoperatiion were compared between two groups.Results:The operation time,hospitalization,fracture healing time of observation group were significantly shorter than those of the control group,and the bleeding amount of observation group was less than that of the control group (P＜0.05).At 1 months after operation,the Constant-Murley scores of observation group were significantly better than those of the control group (P＜0.05).The For Neer scores,excellent rate of observation group (91.1％) were significantly higher than those of the control group (68.1％,P＜0.05).Conclusion:Compared with the traditional open reduction with internal fixation,minimally invasive locking plate was better,safer,faster and more effectively for promoting the recovery of shoulder function of patient with proximal humerus fractures.

The main purpose of this study is to observe and analyze the characteristics and the clinical significance of long-term echocardiogram data in patients after mechanical aortic valve replacement operation. Fifty-five cases were recruited over 5 years after mechanical aortic valve replacement operation, with complete echocardiogram examination profiles. The 55 subjects were divided into predominate aortic stenosis group and predominate aortic regurgitation group, based on preoperative examinations. And another way of division was also carried out that according to the effective orifice area index (EOAI), the subjects were divided into three groups, i. e. , severe prosthesis-patient mismatch (PPM) group, moderate PPM group, and non PPM group. Characteristics of long-term echocardiogram data of the subjects were analyzed. Patients with aortic stenosis showed significantly decreased thickness of intraventricular septum and left ventricular posterior wall about half a year after operation (P < 0.05). Half a year after operation, patients with aortic regurgitation showed decreased left ventricular internal dimension diastole and left ventricular internal dimension systole, and increased ejection fraction (P < 0.05). Differences in mean aortic valve pressure gradient, forward blood flow across the aortic valves, and ejection fraction were not significant among those with severe PPM, moderate PPM, and non PPM groups (P > 0.05). Number of cases of ascending aorta dimension increased as time goes on and pathogenesis of other valve diseases. A conclusion could be drawn that the heart function of patients with aortic valve disease could be improved after mechanical aortic valve replacement operation, but pathologies in other valves and ascending aorta might be increased, and therefore periodical postoperative echocardiogram evaluation with long-term pharmaceutical therapy could be necessary.

Objective To investigate the relationship between hepatitis B virus (HBV) genotype,the mutation in basic core promoter(BCP)region/pre-core(Pre-C)region and the incidence of hepatocellular carcinoma(HCC) in Fusui county of Guangxi Zhuang Autonomous Region (Guangxi),a area with high incidence of HCC. Methods In this case-control study,53 HCC patients and 70 asymptomatic HBV carriers were enrolled. Blood samples were collected from them for serum separation and HBV DNA extraction. The DNA sequences of the S region and BCP/Pre-C region of HBV was determined by direct sequencing following nested-PCR amplification. The relationship between the genotype,gene mutation of HBV and the incidence of HCC was analyzed. Results The mutation rates of the A1762T/G1764A in the BCP region and the T1858C in the Pre-C region of HBV were significantly higher in HCC group than in control group(94.3%vs. 75.7%,P=0.006;50.9%vs. 31.4%,P=0.029). The mutation rate of A1775G was significantly higher in control group (28.6%) than in HCC group (13.2%)(P=0.041). Multiple logistic regression analysis indicated that A1762T/G1764A and T1858C mutations are the risk factors for the development of HCC (OR=5.459,95%CI:1.397- 21.332,P=0.015;OR=3.881,95%CI:1.462-10.305,P=0.006). A1775G is the protective factor in the development of HCC(OR=0.192,95%CI:0.059-0.622,P=0.006). Conclusion The present investigation showed that BCP A1762T/G1764A,A1775G and Pre-C T1858C mutations are correlated with the incidence of HCC in Fusui county of Guangxi.

Objective To perform digital 3D measurement of anatomic parameters associated with vertebral units fixed by ribs and pedicle fixation of T4-T10,providing evidence for clinical application.Methods Spiral CT scan of T4-T10 vertebrae was conducted in 15 normal adults without spinal disorder.The data were imported into computer to establish units and disc models of thoracic and rib vertebrae T4-T10 using Mimics 16.0 software and Ansys 11.0 finite element software.The following data were measured in the vertebral pedicle-rib unit fixation group (group A) by software:transverse diameter of vertebral pedicle-rib unit,length of the outside pedicle screw,inclination angle of pedicle screw,and maximum and minimum inclination angles of pedicle screw;the following data were also measured in the pedicle fixation group (group B) by software:pedicle transverse diameter,length of pedicle screw,inclination angle of pedicle screw,and maximum and minimum inclination angles of pedicle screw.The corresponding parameters were compared between groups A and B.Results In both groups,the transverse diameters and screw lengths gradually increased with the increase in the vertebral sequence while the inclination angle of pedicle screw,and maximum and minimum inclination angles of pedicle screw decreased with the increase in the vertebral sequence.All the parameters in groups A were significantly larger than the corresponding ones in group B (P ＜ 0.05).Conclusions Of the spinal segment of T4-T10,the rib vertebral unit fixation can provide greater safe screw angles and screw diameters for clinical surgery.This is of vital significance for reducing the surgical complexity and improving screw prehension.
