Objective To compare the clinical efficacy of percutaneous kyphoplasty (PKP) by balloon dilatation between unipedicular and bilateral pedicle approach for the treatment of osteoporotic vertebral compression fractures (OVCF). Methods From January 2012 to March 2014, 56 patients with single-level or double- level OVCF were randomly divided into two groups. 29 patients with 33 vertebral bodies were performed by PKP through unipedicular approach and 27 patients with 31 vertebral bodies through bipedicular approach , used PMMA bone cement filling vertebral. The clinical data of patients were prospectively analyzed and the clinical efficacy was compared between two groups. Results The VAS scores, Beck value, Cobb angle and ODI scores after operation improved in both groups (P < 0.01),but there were no significant difference between two groups(P > 0.05). The operative time, X-ray exposure time and volume of bone cement in unilateral group were less than that of bilateral group(P < 0.01). There were no significant difference in the incidence of bone cement leakage ,the pain relief and the incidence of complications between two groups (P > 0.05). Conclusion Both unipedicular and biopedicular PKP are significant improvement for the OVCF, vertebral strengthen showed similar efficacy, but the former has easy operation procedure, can shorten operative time and reduce X-ray exposure time and less volume of bone cement.

Objective: To learn the health literacy level and its influencing factors among junior high school students in Jiaxing, so as to provide basis for health promotion of adolescents. Methods: The junior high school students who had been studying and living in Jiaxing for more than six months were selected by multistage cluster random sampling method. A questionnaire survey was conducted to collect general information and health literacy level (including basic knowledge and concept, healthy lifestyle and behaviors, and basic skills) of these selected students. The multivariate logistic regression model was used to analyze the influencing factors for health literacy. Results : Of 1 773 questionnaires collected, 1 738 were valid, accounting for 98.03%. The level of health literacy in the junior high school students in Jiaxing was 22.84% ( 95%CI: 20.87%-24.82% ), The levels of basic knowledge and concept, healthy lifestyle and behaviors, and basic skills were 55.29% ( 95%CI: 52.95%-57.63% ), 21.75% ( 95%CI: 19.81%-23.69% ), 53.05% ( 95%CI: 50.70%-55.40%), respectively. Multivariate logistic regression analysis showed that the second grade and above ( OR: 1.609-1.835, 95%CI: 1.195-2.459 ), mother's educational level of technical secondary school/senior high school and above ( OR: 1.965-1.976, 95%CI: 1.276-3.357 ), and self-rated academic achievement of medium and above ( OR: 1.881-2.441, 95%CI: 1.359-3.335 ) were the promoting factors for health literacy level of junior high school students; self rated health status as unhealthy ( OR=0.254, 95%CI: 0.089-0.721 ) was an obstructive factor. Conclusions The health literacy level of the junior high school students in Jiaxing was 22.84%. The level of healthy lifestyle and behaviors was the lowest in three aspects. Grade, mother's educational level, self-rated academic performance and self-rated health status may have impacts on health literacy level of junior high school students.

Objective To study the accuracy of preoperative planning and postoperative satisfaction of prosthesis posi?tion by applying the personal surgical cutting guide (PSCG) to total knee arthroscopy (TKA) based on 3D printing technique. Meth?ods In this randomized study, 20 patients were selected from August 2014 to October 2015, who were randomly divided into two groups. In PSCG group, 4 males and 6 females were enrolled, with a mean age of 70.9±6.69 (from 59 to 78) years. In con?ventional instrumentation group, 2 males and 8 females were enrolled, with a mean age of 69.9 ± 6.35 (from 58 to 77) years. The conventional instrumentation group was treated with conventional TKA, while the PSCG group was treated with personal surgical cutting guides. Then the knee valgus angle of patients, the angle between prosthesis components on the coronal and the sagittal plane of two groups were evaluated. Subsequently the correlation of the actual osteotomy amount, the valgus angle, caster angle, external rotation angle between intra? and preoperative planning were compared in the PSCG group. Results Compared with the ideal value of each angle, the mean deviation of the hip?knee?ankle angle 0.77°±0.51°, frontal femoral compo?nent angle 0.37° ± 0.53° and frontal tibial component angle 0.11° ± 0.24° showed statistically significant difference between two groups (P<0.05). The mean deviation of the lateral femoral component angle and the lateral tibial component angle (respectively 8.26°±0.85°, 0.71°±0.77°) were smaller than that of the conventional instrumentation group, while the differences all had no statis?tically significant difference (P>0.05). The actual osteotomy amount, the valgus angle, caster angle, external rotation angle corre?lated well between intra?and preoperative planning (t=-2.547, 3.864, 0.537,-0.040,-1.290, P>0.05). Conclusion TKA assist?ed by PSCG can make lower extremity alignment and accuracy of prosthesis implantation more accurate compared with convention?al TKA, especially in hip?knee?ankle angle, frontal femoral component angle and frontal tibial component angle.

This study is to establish the fingerprint for Phyllanthus emblica and their tannin parts from different habitats by HPLC for its quality control. The determination was carried out on a Diamonsil C18 (4.6 mm x 250 mm, 5 microm) column, with methanol-0.2% glacial acetic acid as mobile phase with gradient elution at a flow rate of 1 mL x min(-1). The temperature was maintained at 30 degrees C and the detected wavelength is 260 nm, Thirteen chromatographic peaks were extracted as the common peaks of the fingerprint of P. emblica, and eleven as the common peaks of P. emblica tannin parts, and five peaks were identified by comparing with referent samples. The fingerprints of 8 samples were compared and classified by similarity evaluation, cluster analysis and principal component analysis (PCA). The similarity degrees of eight P. emblica were between 0.763 and 0.993, while tannin parts were between 0.903 and 0.991. All the samples of P. emblica and their tannin parts were classified into 3 categories. The method was so highly reproducible, simple and reliable that it could provide basis for quality control and evaluation of P. emblica from different habitats.

To investigate the neurotoxic effect of human immunodeficiency virus (HIV) gp120 on cultured dorsal root ganglion (DRG)neurons in vitro, dissociated and organotypic mouse embryo's DRG cell culture models were established. Both dissociated and organotypic DRG cultures were treated with HIV gp120 in different concentration (250 pmol/L and 1 nmol/L, respectively, 2 times/7 days). For dissociated DRG cultural cells, microtubule-associated protein 2 (MAP2) immunofluorescent labeling was processed for observing the changes of neuronal cell body and neurites. The change of the ultrastructure in the organotypic cultured DRG was observed by electron microscopy.The difference of the number and length of neurites between the control group and HIV gp120 treated groups were significant (P＜0.001),whereas there was no significant difference in the diameter of neurons between them (P＞0.05). The ultrastructural changes included the decrease or loss of cristae in mitochondria and accumulation of many high densed particles between the microtubules and the neurofilaments by using both the concentrations of HIV gp120 treatment. The present results indicate that HIV gp120 had a directly neurotoxic effect on the cultured DRG neurons, especially more sensitive to mitochondria.
