OBJECTIVE:To learn the way to improve innovation efficiency of technological development and achievement transformation stages in pharmaceutical industry in China. METHODS:The input and output data of pharmaceutical industry in 28 provinces(regions,cities)of China from 2001-2013 were estimated by using stochastic frontier analysis(SFA)so as to obtain in-novation efficiency of two stages. According to average efficiency of two stages,pharmaceutical industry of 28 provinces(regions, cities)were divided into 4 categories for further analysis. RESULTS & CONCLUSIONS:The innovation efficiency of pharmaceuti-cal industry in China was 0.626 2 at technology development stage and 0.567 8 at transformation stage,indicating they were not high either and the transformation efficiency was lagged behind the development efficiency. The coefficient of variation of innova-tion efficiency at transformation stage(0.274 2)was higher than development stage(0.194 5),indicating the difference degree of innovation efficiency at transformation stage was larger than at development stage. The areas with higher efficiency in both stages were in Eastern and economically developed regions,and the Western region with rich natural resources had higher efficiency at technological development stage,indicating region economic level or resource advantages created the conditions for the pharmaceuti-cal industry to enhance the innovation efficiency. It is suggested to further strengthen scientific achievement communication between pharmaceutical enterprises and pharmaceutical research institutions,and pay more attention to develop national medicine and tradi-tional Chinese medicine in Western region.

Objective To discuss the relationship among Big Five-Personality, Resilience and General Health of the new recruits in a certain troop. Methods 205 new recruits completed the questionnaires, which include NEO Five-Factor Inventory ( NEO-FFI) , Connor-Davidso Resilience Meter (Chinese version) , and General Health Questionnaire (GHQ-12). Results The neuroticism trait of personality positively correlated to General Health( r = 0.50, P<0.001) and significantly predicted mental disease (β =0.4, P<0.01). The self-strengthening dimension of resilience was negatively related to general health ( r = - 0. 51 , P<0. 01 ). Furthermore, self-strengthening played partial mediating role between neuroticism and general health ( Sobel Z =2. 92, P<0. 01). Conclusion The neuroticism trait of personality is a risk factor for new recruits'mental health, while self-strengthening is a protective factor for it.

Objective To investigate the clinic features and risk factors for central nervous system (CNS) infection in patients with systemic lupus erythematosus. Methods Clinical data of 18 cases of hospitalized lupus patients with CNS infection were analyzed retrospectively.Thirty-three lupus patients without CNS infection were selected as control. Results There were significant differences between the CNS infection group and control group in the dosage of corticosteroid used for pulse therapy (22% vs 3%, P<0.05), the aver-age dosage of corticosteroid used within one year (35±18 vs 24±17, P<0.05), peripheral blood leukocyte count (4.4±3.4 vs 6.7±2.9, P<0.05) and lymphocyte count (0.7±0.6 vs 1.5±0.7, P<0.01), and clinical outcome (mortality rate was 22% vs 0, P<0.05). Conclusion The clinical manifestations of CNS infection may be atypical. Large-dosage corticosteroid therapy, higher daily dosage of corticosteroid used, decreased peripheral lymphocytes and leucocytes counts are risk factors of central nervous system infection in lupus patients.

Objective To study the brain development in infants of diabetic mother. Methods The development of cerebral grey matters and white matters was evaluated in 64 infants of pregnant diabetic mother by echoencephalography and medical image analysis system. The parameters were compared with 101 infants of non-diabetic mother. The early brain response function of newborns was assessed. The neurodevelopment after neonatal period was also evaluated. Results The brain in infants of diabetic mathers was immature.The average values of grey density in thalami (76.92?6.60) were significantly lower in full term infants of diabetic mathers than that of the infants of non-diabetic mathers (84.72?6.35). These were also obvious in white matters of frontal lobe [(62.68?5.21) vs (67.60?4.09)] and occipital lobe [(73.39?5.67) vs (78.61?2.95)] (P

Objective To study the hypoglycemic effect of total flavonoids from stems and leaves of scatellaria baicalensis (SSTF)on diabetic mice and to explore the therapeutic mechanism.Methods Diabetic mice models were established by intraperitoneal injection of alloxan(200 mg/kg),and the changes of mice blood glucose ,superoxide dismutase activity and malondialdelyde content were observed after preventive or curative treatment with SSTF.Results Preventive treat- ment with SSTF can obviously inhibit the increase of mice blood glucose induced by alloxan ,and the therapeutic treat- ment with SSTF can lower the blood glucose levels of diabetic mice.Both preventive and therapeutic treatment groups can increase serum superoxide dismutase activity and decrease malondialdelyde content.Conclusion SSTF have significant preventive and therapeutic effects on diabetic mice,and the mechanism is related to the anti-oxidation activity.

BACKGROUND:There are some controversies on the choice of immediate or delayed weight-bearing schemes of implants.
OBJECTIVE: To explore the weight bearing scheme for Bego implants based on implant stability quotient (ISQ) measured by Osstel, and to analyze the factors which influence implants’ stability.
METHODS:Seventy-four single Bego implants with ISQ≥ 50 in 62 patients were selected and randomly
divided into test group (36 single Bego implants in 31 patients) and control group (38 single Bego implants in 31 patients). Patients in the test group were given immediate loading, and patients in control group were given
delayed loading. Two groups’ ISQ of Bego implants after loading (1, 2, 3, 4, 6, 8 and 12 weeks) were compared, and factors which influence implants’ stability were analyzed.
RESULTS AND CONCLUSION:The lowest ISQ for immediate loading of the test group appeared in 2-3 weeks after loading, and that of the control group appeared in 3-4 weeks. There was no statistical difference between two groups on ISQ of Bego implants after bearing (1, 2, 3, 4, 6, 8 and 12 weeks) (P > 0.05). Multiple regression analysis showed that the factors including age, types of osseous substance and implant length were positively related with stability of Bego implants, yet oral hygiene was negatively related with stability of Bego implants. Immediate loading and delayed loading have similar stability to single Bego implants with ISQ≥ 50 measured by Osstel, so individualized weight bearing scheme may be selected according to patient’s own condition under the guidance of Osstel, further to improve implants’ success rate after loading.

BACKGROUND: It is difficult to in vitro isolate and culture the ovarian surface epithelium with high purity, strong vitality and stable biological characteristics. Tissue adherence and enzymatic digestion are commonly used for primary culture, but there are certain problems in cel col ection, cel viability and cel purity. OBJECTIVE: To establish a method for primary isolating, culturing and identifying human ovarian epithelium. METHODS: The ovarian surface epithelium was obtained with cel brush innovatively, and then the cells were isolated and purified with erythrocyte spal ation and differential adherence. The epidermal growth factor was added into the serum-free Dulbecco’s modified Eagle’s medium-F12 medium for cel culture. The cel morphology was observed under inverted microscope, and hematoxylin-eosin staining and immunocytochemical staining were used to identify the cells, then the growth curve was draw. RESULTS AND CONCLUSION: The ovarian surface epithelium became adherent after cultured for 24 hours, and reached fusion basical y after cultured for 6-12 days. The cells were polygonal or flat with strong transparency and refraction. The morphological characteristics of the cells were in line with those of the normal epithelial cells, and almost al the isolated cells could express the epithelial cells surface marker CK19. The cells could be passaged for 6-8 generations with wel growth and the cel growth curve was in “S” shape. The purity of the cells was more than 95%. The results suggest that cel brush method is simple to operate and can obtain a large amount of ovarian surface epithelium rapidly. The purity of the isolated cells can reach to 95% after treated with erythrocyte spal ation and differential adherence method and the cells are in stable growth.

Objective To investigate the clinical significance of anti-β2 glycoprotein Ⅰ(anti-β2GP Ⅰ)antibodies in patients with systemic lupus erythematosus(SLE)and to assess their association with lupus thrombocytopenia.Methods Anti-β2GP Ⅰ antibodies were tested in 108 SLE patients(including 37thrombocytopenia patients),30 patients with rheumatoid arthritis(RA)and 30 healthy individuals by enzyme-linked immunosorbent assay(ELISA).The clinical features and laboratory findings were collected,and the associations of anti-β2GP Ⅰ antibody with laboratory findings and disease activity were analyzed.Results Sensitivities of anti-β2GP Ⅰ antibody were 19.44%(21/108)in SLE and 10%(3/30)in RA,respectively.The specificity of anti-β2GP Ⅰ antibody was 95.0% in SLE.The anti-β2GP Ⅰ antibody titers of the SLE group were significantly higher than normal group(P ＜ 0.05).There was no significant correlation between anti-β2GP Ⅰ antibodies and thrombocytopenia(r =-0.028,P ＞0.05).Anti-β2GP Ⅰ antibody was positively correlated to anticardiolipin antibody(r = 0.566,P ＜ 0.01).No associations were found between anti-β2GP Ⅰ antibody and other clinical and laboratory features.There was no statistical correlation between the level of anti-β2GP Ⅰ antibody and SLEDAI scores.Conclusions Anti-β2GP Ⅰ antibody had high specificity in SLE.There was no significant correlation between anti-β2GP Ⅰ antibodies and lupus thrombocytopenia.

Objective To improve the diagnostic accuracy by analyzing the CT features of primary hepatic sarcoma.Methods The CT findings of 6 cases with primary hepatic sarcoma confirmed by histopathology were analyzed retrospectively,including primary hepatic angiosarcoma 2 cases,and epithelioid hemangioendothelioma,primary hepatic lymphoma,alveolar soft-part sarcoma,undif-ferentiated embryonal sarcoma,1 case each.Results Primary hepatic sarcoma appeared as multiple nodules with heterogeneous and progressive enhencement in one case,and a dominant mass with multiple satellite nodules in another case.Epithelioid hemangioendo-thelioma displayed as multifocal hepatic disease involving both liver lobes,more than half of the lesions were peripheral and extended to the liver margin.Primary hepatic lymphoma demonstrated as an ill-defined low-density lesion with irregular ring enhancement. Alveolar soft-part sarcoma presented as a well-defined low-density lesion with obviously heterogeneous enhancement in arterial phase.Undifferentiated embryonal sarcoma appeared as a huge cystic lesion with slightly margin enhancement.Conclusion The CT findings of primary hepatic sarcoma are associated with the pathological types,combining clinical symptoms with typical CT features are helpful to the diagnosis.The ultimate diagnosis relies on pathology and immune histochemistry.
