Objective To study the characteristics of plasma adiponectin levels exhibiting in gestation women and newborns, as well as the relationships between adiponectin levels and fetal birth weight. Methods Totally 98 subjects have been considered in this study, in-cluding venous blood samples of 36 healthy non-pregnant women (control group), 31 uncomplicated pregnant women (pregnancies group) and the cord blood samples taken at delivery of their singleton infants born at term (newborns group). The concentrations of adiponectin and insulin were determined by radioimmunoassay technique. And SPSS was used for statistical analyses. Results The adiponectin level in women of late period of gestation (WLPG) (11.10±5.72)g/ml was lower than that of other two groups, and the newborns average cord plasma level of adiponectin was (30.71±12.77) g/ml significantly higher than that of the control group (16.52±6.87) g/ml. The adipone-ctin level for WLPG was correlated with FINS and HOMA-IR (r = -0.411, -0.393, P <0.05). The adiponectin level in cord plasma was positively correlated with birth weight(r = 0.416, P < 0.05). The adiponectin level in WLPG was correlated neither with the adiponec-tin level nor body weights of their newborns. Conclusions The average cord plasma adiponectin level of newboms is significantly higher than that of the control group and WLPG. It is positively correlated with birth weight, which suggests that adiponectin may be involved in reg-ulating fetal growth. The adiponectin level in WLPG is correlated neither with the adiponectin level nor body weights of their newborns.

OBJECTIVETo investigate the effect of augmentative locking compression plate combined with bone graft in treating aseptic femoral shaft nonunion after intramedullary nailing.

METHODSTwenty-one cases with aseptic femoral shaft nonunion after intramedullary nailing from January 2007 to January 2013 were treated,including 18 males and 3 females with a mean age of 37.7 years (ranged from 23 to 64 years). The mean period of nonunion after surgery was 23.9 months (ranged from 9 to 62 months). According to Weber-Cech classification,10 of those 21 cases were hypertrophic nonunion,7 were atrophic, and 4 had oligotrophic fracture nonunion. All patients retained the original intramedullary nail, and applied with augmentation plating of 6 to 8 holes locking compression plate, unicortical fixation with 2 to 3 locking screws in the proximal or distal end, with simultaneous autologous iliac bone grafting. After treatment,all patients were allowed to partial weight-bearing until full weight-bearing according to the radiological results. All patients were followed up and were evaluated with clinical and imaging results.

RESULTSAll patients were followed up from 8 to 24 months, averaged (13.5±3.5) months,which showed clinical union at 4 to 8 months, averaged (6.0±1.0) months and radiological solid union at 7 to 12 months, averaged (9.1±1.5) months. No such complications as infection,hardware loosening or breaking were found.

CONCLUSIONAugmentative locking compression plate(LCP) combined with bone graft for aseptic femoral shaft nonunion after intramedullary nail has a satisfied clinical efficacy. It's an useful and simple method.

Objective:To detect the existence of IFNGR in the stellate ganglion in female goats .Methods:The stellate ganglia were taken from female goats .The expression of IFNGR was detected by PCR method and immunohistochemical SP staining .Results:The results showed that:IFNGR immunoreactive substances were distributed in neurons , supporting cells and passing fiber , and mainly in the cytomembrane and nuclei of neurons .The relative expression of IFNGR was very significantly higher than that of non-neuronal cells (P<0.01).The sequence of IFNGR1 gene amplified by PCR method contained 376 bp, and IFNGR1 gene of goats exhibited the highest homology with sheep(98%),followed by cattle(97%).Conclusion:The results suggested that the IFNGR in the Stellate Gan-glion of female goats mainly expressed and located in sympathetic postganglionic neurons which were provided with the conditions for the role of IFN-γ, which implied that the Stellate Ganglion may act as the critical point to concert the immune regulation of IFN -γand neu-roregulation of autonomic nerve on cardiovascular system .

OBJECTIVETo observe the effect of Chinese medicine and pharmacy (CMP) on the mortality of senile HIV/AIDS patients as adjunctive therapy.

METHODSHIV/AIDS patients of a certain rural area of Hanna Province, who were recruited in national CMP HIV treatment trial program (NTCMTP) in 2004, were enrolled as the CMP treatment group. HIV/AIDS patients in the same village without recruiting in NTCMTP were enrolled as the non-CMP treatment group. Data related to subjects were collected from the database of NTCMTP and National HAART Reporting System. Multiple regression analysis under Cox proportional hazard model was applied to examine the risk factors for death of senile HIV/AIDS patients.

RESULTSA total of 436 HIV/AIDS were enrolled in this study, 204 in the CMP treatment group and 232 in the non-CMP treatment group. There were 70 AIDS-relative deaths in the CMP treatment group, with 8-year mortality rate of 37.74%. There were 111 AIDS-relative deaths in the non-CMP treatment group, with 8-year mortality rate of 48.34%. The 8-year mortality rate was higher in the non-CMP treatment group than in the CMP treatment group (chi2 = 5.136, P < 0.05). Results of univariate Cox proportional hazards regression analysis showed the hazard ratio in the non-CMP treatment group was 1.41 times that of the CMP treatment group (P < 0.05). Result of multivariate Cox proportional hazards regression analysis showed the hazard ratio in the non-CMP treatment group was 1.44 times that of the CMP treatment group (P < 0.05). Besides, gender and marital conditions were significantly associated with death of HIV/AIDS patients.

CONCLUSIONCMP treatment was favorable to lower the mortality rate of senile HIV/AIDS patients, and its objective evaluation awaits for further prospective study.
