OBJECTIVETo compare clinical outcomes of bilateral transpedicular balloon kyphoplasty for the treatment of ordinary osteoporotic vertebral compressive fracture (OVCF) and severe osteoporotic vertebral compressive fracture.

METHODSFrom Junary 2009 to Febuary 2011, 60 patients (70 vertebrae) with osteoporotic vertebral compressive fracture were included. All patients were treated by bilateral transpedicular balloon kyphoplasty combined with postural reduction, including 10 males and 50 females aged from 59 to 90 years old with an average of 72.1 years old. In ordinary osteoporotic vertebral compressive fracture group, there were 38 patients (44 vertebrae) including 7 males and 31 females aged from 59 to 87 years old with an average of (71.8±6.1) years old. There were 6 patients with two vertebral fractures, 1 vertebra in T9, 5 vertebrae in T10, 7 vertebrae in T11, 13 vertebrae in T12, 9 vertebrae in L1, 4 vertebrae in L2, 4 vertebrae in L3, 1 vertebra in L4. While in severe osteoporotic vertebral compressive fracture group, there were 22 patients (26 vertebrae) including 3 males and 19 females aged from 63 to 90 years old with an average of (72.6±7.2) years old. There were 4 patients with two vertebral fractures, 1 vertebra in T9, 2 vertebrae in T10, 3 vertebrae in T11, 9 vertebrae in T12, 6 vertebrae in L1, 3 vertebrae in L2, 2 vertebrae in L3. Operative time, volume of bone cement injection, and vertebral height and changes of Cobb angle before and after operation were observed and compared. Postoperative average recovery rate of vertebral height and correct degree of Cobb angle were caculated and compared, VAS scoring were used to evaluate therapeutic effect.

RESULTSAll operations were completed sucessfully, and pain were relieved at 72 h after operation. All patients were followed up from 6 to 13 months with an average of 10.1 months. Postoperative vertebral height, Cobb angle and VAS score were improved better than that of before operation (P<0.05). Operative time in ordinary group was shorter than severe group, while volume of bone cement injection was more than that of severe group. Average recovery rate of vertebral height and correct degree of Cobb angle in ordinarty group was better than that of in severe group (P<0.05). There was no significant differences between two groups in VAS scores before and after operation (P> 0.05). Three cases (3 vertebrae) ocurred bone cement leakage in ordinarty group, while 5 cases (5 vertebrae) ocurred bone cement leakage in severe group, and there was no meaning between two groups (P>0.05).

CONCLUSIONKyphoplasty could receive satisfied curative effect in treating ordinary and servere patients with osteoporotic vertebral compressive fracture, but recovery of vertebral height and correct degree of Cobb angle in ordinary gourp was better than that of in servere group.

OBJECTIVE:To provide data and reference for pharmacist legislation. METHODS:Questionnaire survey was de-signed investigate and analyze the staffing situation,education level,professional composition,age composition,professional titles composition,continuing education and wage of pharmacists who worked in medical and health institutions from 16 states (cities) in Yunnan province,and suggestions were put forward for relevant legislation. RESULTS:Totally 10 questionnaires were received from provincial medical and health institutions,and 16 from state (city) Health and Family Planning Commission,with effective recovery of 100%;data covered 1 561 medical and health institutions,involving 7 409 pharmacists. The numbers of pharmacy per-sonnel/hospital beds in tertiary hospitals,secondary hospitals and class-1 hospitals were 1∶15.49,1∶17.50,1∶20.68,numbers of pharmacy personnel/health professional and technical personnel in hospital accounted for 5.62%,6.18%,5.30%,respectively;most pharmacists in tertiary hospitals were mainly undergraduate degree(35.21%),doctor degree accounted for 0.15%,the high-est ratio of education was junior college degree in secondary hospitals(41.60%)and class-1 hospitals(57.51%);most pharmacists graduated in pharmacy in tertiary hospitals(94.14%),70.22% in secondary hospitals and only 10.50% in class-1 hospitals;phar-macy personnel mainly held the pharmacist professional titles in tertiary,secondary and class-1 hospitals (33.83%,37.89% and 63.55%),senior professional titles accounted for 5.88%,2.71% and 0.21%,respectively;only a few have learning experience and almost less than 6 months (9.17%,5.84% and 21.32%),and 80 pharmacists were certificated as clinical pharmacists in the whole province;generally,all wage was concentrated in 2 000-2 999 per month (27.72%,41.80% and 55.90%,respectively). CONCLUSIONS:Shortage of hospital pharmacists and lack of senior personnel are the main problems in Yunnan province,and wage is not high,especially in primary hospital,this situation is more obvious. The current situation of pharmacists in the hospital should be more taken into consideration during the legislative process in aspects of clearing and guaranteeing access qualifications, responsibilities,status,rights and interests,and pharmaceutical technology and service charges should be established.

Objective To investigate the role of hypoxia inducible factor-1α (HIF-1α) and von Hippel-Lindau (VHL) in murine endochondral ossification. Methods The knockout of HIF-1α or VHL gene in murine osteoblasts was accomplished by conditional knockout technique at 4th, 8th and 12th week, and the differences between wild-type group and knock-out group in endochondral ossification were detected by HE staining, micro-CT scanning, trabecular bone area measurement, calcium content measurement, tetracycline fluorescence labeling, Real-time PCR and Western blotting. Results After knockout of HIF-1α gene in osteoblasts, the expression of vascular endothelial growth factor ( VEGF) reduced, the rate of new bone formation stepped down, the content of calcium became less, and the trabecular bone volume decreased (P <0.05) . After knockout of VHL gene in osteoblasts, the expression of VEGF increased, the rate of new bone formation stepped up, the content of calcium became more, and the trabecular bone volume was promoted (P < 0.001). Conclusion During murine endochondral ossification, VHL/HIF-1α signal pathway promotes angiogenesis through the stimulation of VEGF expression, which subsequently accelerates osteogenesis.
