Objective To study the influence of valsartan combined with indapamide on the UmAlb level and blood pressure in patients with hypertension and diabetes mellitus.Methods 90 patients with hypertension and diabetes mellitus were selected and randomly divided into three groups by number table.30 cases of the control group A were treated with indapamide,30 cases of the control group B were treated with valsartan,30 cases of the observa-tion group were treated with indapamide combined with valsartan.After treatment,the clinical parameters and effect of the three groups were compared.Results After treatment,the systolic blood pressure and diastolic blood pressure of the three groups were decreased(all P <0.05),and the observation group decreased obviously(all P <0.05).The total effective rate of the observation group was 96.7%,which was higher than 86.6% of the control group A and 83.3% of the control group B(χ2 =4.1 2,4.22,all P <0.05).Conclusion In the treatment of hypertension and diabetes,the antihypertensive effect of indapamide combined with valsartan is obvious and can protect the renal func-tion,which should be promoted in clinical use.

OBJECTIVE To control abuse use of antibiotics.METHODS Various methods were used to strengthen the management of antibacterials,for example,fully exert the rational use antibiotics,enforce the training of the doctors and nurses for the rational use of the antibiotics,and stipulate the rules and principles for the use of antibiotics.RESULTS The management of antibacterials was strengthened,and the rational use of antibiotics was improved.CONCLUSIONS To enhance surveillance of antibacterial use and prevent antibacterial unrational use are propitious to control occurrence of nosocomial infections.

Objective To assess the relative value of individual positions in the functional departments of a general hospital in Beijing,for reference of improving the salary allocation system and fine management of human resources.Methods The expert consultation method and International Position Evaluation system were used to quantitatively assess the tasks,work difficulty,size of responsibility and the qualifications required for every.Results A total of 38 experts contributed to this research which studied 140 positions including all functional departments of this hospital.The department having the most positions is the finance department(17)and the least is the Youth League committee(1).The position scoring the highest(805)was the director of medical affairs department;that scoring the lowest(263)was the food and beverage service positions of the diet and nutrition department.There was an evident turning point at score 547.Conclusions Functional departments′ position setting of this hospital proves reasonable,and the assessment scoring can reflect the value of the position in related dimensions.The result can be used as reference indexes for the hospital to perfect its human resource management system and improve the remuneration precision.

This article was aimed to study the protection effects of Pa-Bing Formula No. 2 (PBFN-2) on neurons of substantia nigra in Parkinson's disease (PD) rats models in order to explore the possible mechanism of PBFN-2 in PD treatment. Rats were stereotaxically injected with 6-hydroxydopamine (6-OHDA) solution into the left stria-tum in two-site. Rat showed consistent right whirling and the number of rotation was more than 7 r·min-1 induced by APO in 30 min, then the rat was judged as PD model. A total of 14 rats modeled successfully were randomly di-vided into the model group and the treatment group. At the same time, the normal group and sham operation group were also established. Same volume of distilled water was given to the normal group, sham operation group and the model group. PBFN-2 (32.0 g·kg-1) was given to the treatment group for 4 weeks. Microscope was used to observe pathological changes of substantia nigra by nissl stain and changes of TH, Nrf2 and HO-1 immunohistochemical stain. The results showed that compared with the normal group, the nissl bodies were badly injured. Expressions of TH-positive cells were obviously reduced (P<0.01). The expression of Nrf2 nucleus protein and HO-1 protein were obviously increased in substantia nigra of PD rats in model group (P<0.01). Compared to the model group, PBFN-2 effectively increased nissl bodies in neuronal cells of substantia nigra of PD rats, and elevated the number of TH-immunoreactive cells in substantia nigra (P<0.05). The expressions of Nrf2 nucleus protein, HO-1 protein were significantly up-regulated (P<0.05). It was concluded that PBFN-2 had an obvious neuroprotection on the neuronal cells in substantia nigra of PD rats induced by 6-OHDA. The underlying mechanisms may be associated with regu-lation of Nrf2 nucleus protein and HO-1 protein expressions.

Aim To investigate how Farnesoid X re-ceptor (FXR),a nuclear hormone receptor,acts on neurological behaviors such as emotion,social behav-ior,memory and so on.Methods FXR’s function in central nervous system was evaluated by conducting a battery of behavioral tests including elevated plus maze test (EPMT),forced-swimming test (FST),social in-teraction test (SIT ), and passive avoidance test (PAT),and the contents of neurotransmitters were de-termined by the LC-MS /MS method in FXR knockout (KO)female mice and their wild-type controls.Re-sults FXR KO mice showed significantly increased immobility time in FST (P <0.01 ),and it showed in-creased tendency to enter the open arms in EMPT (P<0.01 ).The number of probing the open arms by FXR KO mice was more than that of the controls.Mo-reover,in SIT,FXR KO mice had remarkably in-creased sniffing interactions with the stranger mouse in the same cage (P <0.01 ).But in PAT,the latency for FXR KO mice to enter the dark chamber on the test day and the number of FXR KO mice to enter the dark chamber didn’t differ from those wild-type mice.In hippocampus,the contents of GABA,Glu,and NE were decreased prominently in FXR KO mice (P <0.05,P <0.05 and P <0.01 ,respectively)as well as the ratio of GABA to Glu (P <0.05).But in pre-frontal cortex,none of the neurotransmitters examined showed any difference between FXR KO mice and their controls.Conclusion FXR may be involved in main-tenance of the homeostasis of neural transmission in the central nervous system,thereby influences the emotion-al and social behavior in animals.

Aim To investigate the changes of behav-iors,neurotransmitters and depression related gene ex-pressions in hippocampus of C57BL/6 mice after olfac-tory bulbectomy (OB).Methods Forced swimming test (FST),tail suspension test (TST),open filed test (OFT),and elevated plus maze test (EPMT) were used to evaluate the behavioral changes 18 days after surgery. LC-MS/MS method was employed to measure the hippocampal neurotransmitters.Quantita-tive PCR approach was established to determine the hippocampal gene expressions associated with depres-sion.Results OB mice were hyperactive in OFT (P<0.05 ) accompanied with increased time spent in open arm of EPMT (P<0.01).Meanwhile,the sur-gery led to the reduction of the ratio of 5-HIAA/5-HT (P <0.01 ) but the increase of Glu/GABA (P <0.01 ) in hippocampus.Moreover,OB elevated the gene expressions of BDNF,Trkb,GDNF,CD1 1 b and TNF-αbut down-regulated that of TPH2 in hippocam-pus (P<0.05 ).Conclusion Behavioral alternation of OB mice was a result of comprehensive effect of the changes of neurotransmission and depression related genes,which call us special attention in using OB as an animal model for research and development of anti-depressants.
