Objective To explore feasibility and clinic results of the MIPPO (minimally invasive percutaneous plate osteosynthesis) technique in treatment of humeral fractures. Methods 14 patients with humeral fracture underwent the MIPPO operation in our department. 7 of them were injured in a traffic accident, 4 in sports and 3 in daily life. There were 11 males and 3 females, with their ages ranging from 16 to 72 years. Of the 14 cases, 9 were proximal ones and 5 mid- distal ones, 3 were multiple injuries and 1 pathological fracture. Results The average intra- operative time was 80 minutes (ranging from 55 to 130 minutes). No patient received blood transfusion. The intra- operative blood loss was 100 to 200 mL. 14 cases were followed up for 8 weeks to 14 months. Their cuts healed at the primary stage. Their shoulder and elbow functions were fine. The fracture segments got satisfactory reduction with good apposition and alignment radiologically. The callus appeared 4 to 8 weeks postoperatively. Conclusion MIPPO is a safe and effective treatment for the humeral fracture with the benefits of less invasion, fewer complications and higher union rate.

Objective To explore the clinic results of the locking compression plate fixation for injuries at the posterior ring of pelvis. Methods 5 patients with injuries at the posterior ring of pelvis were treated with locking compression plate fixation. 2 of them resulted from crashing, 2 from crushing and 1 from falling. They included 4 males and 1 female and their average age was 35.6 years. According to AO classification system, there were 1 type B1, 2 type B2, 1 type B3 and 1 type C1; according to Dennis classification system, there were 4 section I fractures and 1 section II fracture. Results All the patients were available at follow-up, with a mean period of 5.8 months (ranging from 3 to 12 months). The average intraoperative time was 50 minutes (ranging from 30 to 80 minutes), and no patient underwent blood transfusion because the intraoperative blood loss was only 100 to 400 mL. There was no iatrogenic nerve injury and all the incisions healed during the primary procedure. The function and sense of sacroiliac joint and low extremities recovered to normal. Conclusion The locking compression plate fixation is one of the effective methods for treatment of injuries at the posterior ring of pelvis, for it is simple and minimally traumatic, and has a low rate of complications.

Objective To validate the technique and establish the reference jitter values in voluntarily activated extensor digitorum communis using a concentric needle electrode (CNE) in healthy Chinese adults.Methods From January to August 2013,forty-two Chinese subjects from healthy examination center of our hospital were prospectively studied,including 20 males and 22 females.Routine electromyogram was tested and jitter was recorded with CNE in all subjects.The jitter values of action potentials pairs of muscle fibers were expressed as the mean consecutive difference (MCD) after 20 analyzed potential pairs.Results The mean MCD of 42 subjects was (23.0 ± 3.1) μs ranging from 17 to 32 μs.The mean jitter value of all 840 potential pairs was (22.8 ± 7.5) μs ranging from 8 to 54 μs.Upper 95％ confidence limits for mean MCD and individual MCD were 29.2 μs and 37.8 μs,respectively.The mean value of MCD of 20 males and 22 females were (23.2 ± 2.8) μs and (22.8 ± 3.4) μs,respectively.There was no statistic difference between genders in MCD (t =0.44,P =0.66).There was no correlation between age and MCD (r =0.11,P =0.48).The mean value of mean interpotential interval was (802 ± 139) μs ranging from 541 to 1 160 μs.Conclusion The present study confirms the suitability of jitter analysis with CNE,which can serve as an objective and valuable method for testing the function of neuromuscular conjunctions.

Objective To investigate the detection of human bocavirus (HBoV) in children with acute respiratory infection and to explore the relationship between viral load and clinical characteristics of acute respiratory infection in children.Methods A total of 4 501 nasopharyngeal secretion samples were collected from hospitalized children with acute respiratory infection from January 2013 to June 2013.HBoV-positive children were divided into simple infection group and mixed infection group.Children with HBoV DNA≥1 × 104 copy/mL were categorized into high viral load group,while those with HBoV DNA ＜1 × 104 copy/mL were categorized into low viral load group.HBoV was determined by fluorescence quantitative polymerase chain reaction (PCR).Respiratory syncytial virus (RSV),influenza virus (Inf)-A,Inf-B,parainfluenza virus (Pinf)-Ⅰ 、Pinf-Ⅱ 、Pinf-Ⅲ and adeno virus antigen were detected by direct antigen-specific immunofluorescence assays.Mycoplasm Pnuemonia was detected by real-time fluorescence quantitative PCR.Serum mycoplasma antibodies were detected by enzyme-linked immunosorbent assay (ELISA).Bacteria was detected by sputum culture.Over the same period,23 children undergoing elective inguinal hernia operation with no respiratory infection or fever were considered as control group.The percentage of peripheral blood T lymphocyte subsets were tested by flow cytometry.Inter-group differences were compared using Chi-square test or Fisher exact test.Viral loads were compared using Mann-Whitney test.Results Two hundred and twenty-two HBoV-positive cases were detected with a positive rate of 5.41％ (222/4 105),33.33％ (74/222) of which were with high viral load and 66.67％ (148/222) were with low viral load.There was a high incidence in the age group of 1-2 years.The simple HBoV infection accounted for 24.32％,including 26 cases with high viral load and 28 cases with low viral load.Wheezing was more common in patients with high viral load than those with low viral load,and the difference was statistically significant (88.46 ％ vs 42.86 ％,x2 =12.295,P=0.001).Among the 222 HBoV-positive cases,the median viral load of HBoV in simple infection group was 3.86 × 103 copy/mL,and 1.0× 103 copy/mL in mixed infection group.The difference of the viral load between these two groups was statistically significant (Z =2.906,P =0.004).Mycoplasma and Streptococcus pneumonia were most commonly detected in the 168 patients with mixed infection.Percentages of CD3+ and CD3+/CD8+ subsets were significantly lower in HBoV simple infection group and mixed infection group,compared to control group (both P＜0.05).However,percentages of CD3 /CD19+,CD19+/ CD23+ subsets were significantly higher in HBoV simple infection group and mixed infection group,compared to control group (both P＜0.05).Conclusions HBoV is one of the pathogens causing acute respiratory tract infection in children,which lead to cellular immunity dysfunction in children.Moreover,children with higher HBoV load are more likely to develop wheezing.Co-infection with other pathogens should be considered in children with low HBoV load.

By analyzing data from a questionnaire survey on bilingual teaching, we evalueted the results of bilingual teaching for seven-year medical students and the main problems of bilingual teaching and solutions accordingly. An uneven English level on the part of teachers and students and imperfect materials etc. affect the overall results of bilingual teaching. Therefore persistent efforts need to be made in enhancing the teachers' English level, improving teaching methods and compiling proper textbooks so as to genuinely improve the bilingual teaching program.

Objective To invstigate the effect of high dose X-ray irradiation on the expression of multidrug resistance-1 (MDR1), Bcl-2, MMP7 genes. Methods A nasopharyngeal carcinoma cell line,CNE1, were irradiated with a total dose of 50 Gy. The resistance to the cisplatin of CNE1 cells and the irradiated CNE1 (CNE1 R) cells was detected by MTT. mRNAs expression of MDR1 , Bcl-2 and MMP7 was measured by quantitative RT-PCR. Results The expression of MDR1 increased in CNE1 R cells. The semiquantitative A value of MDR1 mRNA was 0.47 ±0.04, and the value of CNE1R cells (1st, 7th, 21st,28th, 35th, 42nd and 49th days after irradiation) were 0.67 ± 0. 06 (t = -5.44, P = 0. 003) ,0.70 ± 0. 01(t=-5.90,P=0. 002),0.73±0. 01(t= -6. 45,P=0. 001) ,0. 67 ± 0. 03 (t= -3.97,P=0.011),0.65 ±0.01(t = -4.43,P=0. 007),0. 62±0. 05(t= -2. 64,P=0.046) and 0.62 ±0.02(t = -3.34,P=0.021), respectively. Bcl-2 mRNA expression were 0.55 ±0.02 and 1.05 ±0.04(t = -9.93,P=0. 000) and MMP7 mRNA expression were 0.51 ±0.01 and 0.82 ±0.02(t = -8.51,P=0.000) in CNE1and CNE1 R cells. Conclusions The MDR1 expression was increased after a total dose of50 Gy irradiation,which may be related to the synchronous change of Bcl-2 and MMP7 genes.
