Objective To study comprehensive methods for senile hypertension and compared with conven-tional western medicine treatment,and provide reference to guide clinical hypertension treatment for the future. Methods 162 cases with senile hypertension were selected in our hospital,according to the order of treatment and the principle of informed consent,they were randomly divided into observation group and control group.The control group was given conventional western medicine treatment,the Nifedipine sustained release tablets joint irbesartan tab-lets.Based on the thinkings of health management,we established health records for observation group firstly,then as-sessed cardiovascular risk among patients.The patients with low,moderate risk were conducted the continuous monito-ring of blood pressure,health education,the key intervention in their way of life,established a good mentality.If the blood pressure was still unstable and out of control,we began to consider the use of drug.For patients with high risk or very high risk,besides the treatment considered,they needed immediate medical treatment supplemented by traditional Chinese medicine.Observation group was followed up for 1 time,and lasting for 6 months,then their blood pressure was measured again,the treatment effect and adverse reactions were evaluated.Results The total effective rate of ob-servation group was 96.7% (89 /92),which was significantly higher than that of control group 82.8% (58 /70),χ2 =9.12,P <0.01,the difference was statistically significant.After following up for 6 months,the systolic blood pressure of observation group fell to (126.1 ±21.5 )mmHg,t =7.548,P <0.01;diastolic blood pressure fell to (79.5 ±9.5)mmHg,t =10.703,P <0.01,the change was significantly different than before.The systolic blood pres-sure of control group fell to (145.3 ±26.7)mmHg,t =1.979,P <0.05,there was markedly reduced,diastolic blood pressure decreased too,but there was no statistical difference (P >0.05).So the effect of observation group was better than control group.Meanwhile,some adverse reaction occurred in both groups,but there was no significant difference. Conclusion With the thinking of health management for aged patients with hypertension,offer full -course treatment for them in order to increase the awareness of hypertension and establish healthy lifestyle,guide scientific and rational drug use.The integrated use of these methods can effectively improve the effect of the treatment of senile hyperten-sion,which is worthy of popularization and application.

BACKGROUND:The Specification of Quality Management for Medical Device Production (for Trial Implementation) issued by the China Food and Drug Administration (CFDA) on December 16, 2009 was demanded to be initially implemented in medical device manufacturers with a higher risk in sterility and implant before January 1, 2011. The revised version was published on December 29, 2014 and came into effect on March 1, 2015. OBJECTIVE:To put forward specific suggestions through analyzing the status of 31 sterile implantable medical device manufacturers in Sichuan Province and the corresponding implementation situation of the specification for trial implementation. METHODS:The relevant data of these 31 manufacturers were collected through the quality management system assessment, supervision and inspection, flight inspection and questionnaire survey. And the data were analyzed statistically. RESULTS AND CONCLUSION:The overall size of medical device manufacturers in Sichuan Province is small. There are still some other problems, such as no advanced equipment, low quality of employees, lack of funds and inappropriate management, in these manufacturers. Considering these, we have given some guiding recommendations from the aspects of production and supervision.

Objective To observe the protective effect of Naoli Zhibao(NZ) on mice with learning and memory impairment.Methods (1) Thirty-two NIH mice were randomized into pseudo-operation group,model group,and low-and high-dose NZ groups(at the dose of 4 and 8 g?kg-1?d-1 respectively).Except the pseudo-operation group,the mice in other groups received the operation of cerebral ischemia/reperfusion.After treatment for 10 days,the learning and memory abilities of the mice were observed by step-down test,and the contents of malondialdehyde(MDA) and nitric oxide(NO) as well as the activities of superoxide dismustase(SOD) and glutathione peroxidase(GSH-Px) were detected.Meanwhile,the free amino acid content in mice cerebral cortex was measured with high performance liquid chromatography.(2) Forty NIH mice aged 9 months were randomized into normal control group,mimetic aging group,and low-and high-dose NZ groups(at the dose of 4 and 8 g?kg-1?d-1 respectively).The mice models of mimetic aging were induced by intraperitoneal injection of D-galactose 0.5mL for 6 weeks,and the mice in NZ groups were also given gastric gavage of NZ for 6 weeks.After treatment,the learning and memory abilities of the mice were observed by step-down test,and the contents of epinephrine(E),norepinephrine(NE) and tryptophan(TP) in mice cerebral cortex were measured.Results (1) NZ significantly improved the memory ability of mice with cerebral ischemia/reperfusion injury(P

OBJECTIVE:To investigate the work status of clinical pharmacists in West China Hospital of Sichuan University and to provide rational suggestions for the development and improvement of clinical pharmacy. METHODS: The status of hospital clinical pharmacy and training of clinical pharmacy were studied by a questionnaire survey on 26 clinical pharmacists and an interview on 9 trainees majored in clinical pharmacy. RESULTS: The major tasks for hospital clinical pharmacists were to participate in clinical rounds, conduct pharmacy rounds alone, participate in patients’ treatment and outpatient pharmaceutical care, listen to case discussion, participate case consultation, coordinate with doctors to make medication plan, collect adverse drug reactions and give lecture among physicians etc. The pharmacists were welcome by most of the clinical departments. CONCLUSIONS: Clinical pharmacy in West Hospital of Sichuan University achieved a good beginning, but to achieve a further progress, the focus of clinical pharmacists’ work should be shifted to provide patient-centered pharmaceutical technical service, meanwhile, the support offered and the importance attached by the government as well as the efforts of clinical pharmacists are indispensible.

Objective To investigate the expression of C/EBP homology protein (CHOP) in peripheral brain tissue of patients with severe traumatic brain injury (TBI) and its correlation with the injury severity.Methods The study included peripheral brain tissues of 41 TBI patients (TBI group).Another 16 autopsy specimens succumbed to other diseases (except for TBI or other central nervous system diseases) were selected as controls.The control group and TBI group were subdivided into immaturity group (≤18 years),adult group (18-59 years) and elderly group (＞59 years).According to Glasgow Coma Scale (GCS) on admission,TBI group was classified as severe TBI group (GCS of 6-8) and particularly-severe TBI group (GCS of 3-5).CHOP expression in peripheral tissues after TBI was compared in between different age,gender and GCS.Nerve cell apoptosis was detected by TUNEL technique and correlation between CHOP level and apoptotic number was analyzed.Results There were no age and gender differences regarding CHOP expression in control group (P ＜ 0.05).Compared with control group,expression of CHOP presented notable up-regulation in TBI group (P ＜ 0.05).Expression of CHOP presented no gender difference in TBI group (P ＞ 0.05),but its expression was lower in the aged than in adult or immaturity (P ＜ 0.05) as well as notably higher in particularly-severe TBI group than in severe TBI group (P ＜ 0.05).Nerve cell apoptosis in TBI group was far greater in number than that in control group (P ＜0.05).A positive correlation was observed between CHOP level and apoptotic index (r =0.72,P ＜ 0.05).Conclusion Expression level of CHOP after TBI is closely related to the injury severity and nerve cell apoptosis,but the apoptosis pathway induced by CHOP may not be a major factor in secondary brain injury after TBI in the aged patients.

OBJECTIVE:To observe the efficacy and safety of Guizhi fuling capsule combined with mifepristone in treatment of uterine fibroids. METHODS:116 patients with uterine fibroids were randomly divided into control group and observation group. Control group was orally given Mifepristone tablet 25 mg,2 h before meal in the first day of menstrual period,once a day,for con-tinuous 10 d;observation group was additionally given Guizhi fuling capsule 3 pills in non-menstrual period,3 times a day. 3 months was regarded as a treatment course,it lasted 2 courses. Clinical efficacy,and E2,FSH,SHBG,uterine volume,menstrual blood volume,uterine fibroid volume and incidence of adverse reactions in 2 groups before and after treatment were observed. RE-SULTS:Total effective rate in observation group was significantly higher than control group,the difference was statistically signifi-cant(P<0.05). After treatment,the FSH,E2,uterine volume,menstrual blood volume and uterine fibroid volume in 2 groups were significantly lower than before,and observation group was lower than control group,the differences were statistically signifi-cant(P<0.05);but there were no significant difference in the SHBG and adverse reactions between 2 groups(P>0.05). CONCLU-SIONS:The clinical efficacy of Guizhi fuling capsule combined with mifepristone in treatment of uterine fibroids is more signifi-cant than mifepristone alone,with good safety.
