Objective To investigate the protective effect of the ethanol extract of vacciniuin bracteatum thumb leaf on acute liver injury induced by CC14 in mice. Methods Sixty mice were allocated into 6 groups randomly, respectively as the normal control group,the model group,the positive control group,the ethanol extract low,middle and high dose group. Each group had 10 mice. Acute hepatic injury model of mice was made by using CC14. The level of ALT, AST in blood serum and SOD,MDA in hepatic tissue were observed. The hepatic tissue was HE-stained conventionally and observed. Results Acute liver injury in mice could be successfully induced by CC14 ,as demonstrated by increased serum ALT, AST levels and severe histological observations. Pretreatment with the ethanol extract of vaccinium bracteatum thumb leaf indicated its potent protective effects on acute liver injury, as demonstrated by a significant decrease in ALT, AST and MDA. Conclusion The ethanol extract of vaccinium bracteatum thumb leaf had an obviously protective effect on acute liver injury induced by CC14, which could be due to its antioxidative stress effect.

BACKGROUND: With the increase of senile population, it needs to further improve their mental health when improving their physical health. To study the depressive status of retired elderly people in order to provide basis for effective community nursing intervention.OBJECTIVE: To investigate and analyze the depression incidence among retired elderly people and conducted correlative factors analysis in order to improve the nursing service to aged people's mental health.DESIGN: Cross-sectional sampling study towards retired senior people.SETTING: Nursing department of a medical college.PARTICIPANTS: This study was completed in Nursing Department of North China Coal Medical College during September to December 2002. It conducted questionnaire survey to 1 000 retired people in Tangshan city by family visit. There were 574 male and 426 female who aged from 60 to 88years old with mean age of 67 years.METHODS: To adopt geriatric depression scale and general condition questionnaire investigation to individuals.MAIN OUTCOME MEASURES: Depression scale score, depression incidence and frequency of correlative factors RESULTS: Mild depression accounts for 17.2% while moderate and severe depression account for 5% among retired elderly people. There is close relationship between factors such as retired veterans, female, low education,lack of social support, empty life, lack of exercise and poor self-assessed health and depression incidence(x2 = 9.80 - 175.93, P < 0. 05).CONCLUSION: The incidence of senile depression among retired elderly people is pretty high so that it is important to pay attention to mental care towards retried people when doing community nursing, especially to divorced, widowed, female and low educated retired people.

OBJECTIVE:To investigate the characteristics and regularity of lornoxicam related ADR,and to provide reference for rational and safe use of lornoxicam. METHODS:From Jan. 1,2006 to Dec. 31,2013,lornoxicam related ADR reports collect-ed by National ADR Monitoring System in Beijing were analyzed retrospectively about their characteristics and related factors. RE-SULTS:In the statistical period,there were 48 ADR reports related to lornoxicam. The people over 40 years age accounted for 62.5%. 38 patients used lornoxicam by intravenous infusion or intramuscular injection ,accounting for 79.17%. The clinical mani-festations were diverse and complex,in which skin(32.96%)and gastrointestinal damage(25.00%)were more common ADR oc-curred within 30 min,accounting for 35.42%,and it would be better after stopping drug or 1-3 days symptomatic treatment. CON-CLUSIONS:The rational use of lornoxicam can reduce the occurrence of ADR. Suggestion on the use of the drug,is that the pa-tient should be monitored for security,in order to reduce the risk of ADR.

Objective To optimize the process of extracting total saponins from Platycodon grandiflorum by orthogonal experimental design and central composite design-response surface method. Methods Independent variables were concentration of ethanol, reflux extraction time, reflux time and solvent fold. Dependent variables were extraction rate of total saponins in Platycodon grandiflorum and the yield of dry extract.Linear or nonlinear mathematic models were used to estimate the relationship between independent and dependent variables. Results The result of the orthogonal experimental design was 70%ethanol, 180 min for reflux, 6 fold of solvent and 2 times for extraction. The result of central composite design-response surface method was 70% ethanol, 140 min for reflux, 10 fold of solvent and 2 times for extraction. Conclusion The central composite design-response surface method is better than orthogonal experimental design in studying extraction process of Platycodon grandiflorum, which provides basis for feasibility of application of central composite design-response surface method in optimization of extraction process of Chinese traditional medicine.

OBJECTIVE:To investigate the effects of different doses of sufentanil citrate on hemodynamic indexes and stress response indexes of Crouzon syndrome children with craniofacial reconstruction. METHODS:60 cases of Crouzon syndrome under-going craniofacial reconstruction were selected from our hospital during Jan. 2010-Jan. 2016,and then randomly divided into group A,group B and group C,with 20 cases in each group. 3 groups were given pump injection of Propofol injection 4-8 mg/(kg·h)for anesthesia induction+Sufentanil citrate injection [group A 0.3 μg/(kg·h),pump injection;group B 0.6 μg/(kg·h),pump injection;group C 1.0 μg/kg,iv,0.5 h/time] for anesthesia maintenance, Cisatracurium besilate for injection 0.1 mg/kg,iv,every 40 min, drug withdrawal 5 min before the end of surgery. The hemodynamic indexes(MAP,HR)and stress response indexes(ACTH,cor-tisol)were observed in 3 groups at different time points as well as the occurrence of ADR. RESULTS:MAP levels of group C at 5 min after skin incision,1 h after operation and immediately at the end of surgery were significantly higher than before anesthesia, while those of group B were significantly higher than group C at same time points. HR of group A at 1 h after surgery and that of group B at 5 min after skin incision and 1 h after surgery were significantly higher than before anesthesias;HR of group B at 1 h after surgery was significantly lower than that of group A,and its HR at 5 min after skin incision and 1 h after surgery were signifi-cantly lower than those of group C. ACTH levels of 3 groups at 5 min after skin incision,1 h after surgery and immediately after the end of surgery were significantly higher than before anesthesia. ACTH levels of group B at 5 min after skin incision,1 h after surgery and immediately after the end of surgery were significantly lower than those of group A and C,and the group A was signifi-cantly lower than the group C at same time points. Cortisol levels of group A at 1 h after surgery,and those of group C at 5 min af-ter skin incision,1 h after surgery and immediately after the end of surgery were significantly higher than before anesthesia. Corti-sol levels of group B at 1 h after surgery were significantly lower than those of group A;cortisol levels of group A at 5 min after skin incision and immediately after the end of surgery and those of group B at 5 min after skin incision,1 h after surgery and imme-diately after the end of surgery were all significantly lower than those of group C. There were statistical significance all above(P<0.05). No obvious ADR was found in 3 groups. CONCLU-SIONS:Pump injection of sufentanil citrate 0.6 μg/(kg·h) can maintain analgesic effect of Crouzon syndrome children with craniofacial reconstruction,can keep hemodynamics sta-ble and effectively inhibit stress response during surgery with good safety.
