OBJECTIVE:To develop a RP-HPLC method for determining the concentration of chlorhexidine(Ⅰ) in mouse serum METHODS:Ⅰ and the internal standard,diazepam,were extracted to ethyl acetate with sodium laurysulfonate as ion-pair Chromatographic separation was achieved on ?-Bondapak C18 column(3 9mm?300mm,10?m)equilibrated with 0 02mol/L potassium dihydrogen phosphate buffer solution (pH=3)∶methanol(44∶56,V/V),with UV detection at 257nm RESULTS:The calibrotion curve of Ⅰ was linear in the range of 0 5～10?g/ml,r=0 9 997 The avarage recovery was 104 67%(n=6) The within-day and between-day RSDs in serum concentrations of 1?4?8?g/ml were 1 5%?0 37%?0 26% and 2 45%?0 46%?1 27% respectively The minimum detectable concentration was 0 4?g/ml CONCLUSION:The developed method was sensitive,accurate and suitable for the determination of Ⅰ in mouse serum

OBJECTIVE:To investigate the anti-adherence effect and its mechanism of Xingnaojing(XNJ)injec?tion.METHODS:In mixed culture of rabbit’s PMN and brain microvascular endothelial cell(BMVEC),the effects of XNJ on LPS-induced PMN-BMVEC adhesion and the changes of PAF and NO levels were observed.RESULTS:XNJ could obviously decrease the PMN-BMVEC adhesion rate and the levels of NO and PAF in culture medium.CONCLUSION:XNJ can inhibit adhesion of PMN to BMVEC and release of some inflammatory media.The decrease of some inflammatory media may related to the reduction of adhesion.

0 05). A negative correlation was found between p16 expressions and the histological grade, clinical TNM stage, lymph-node metastasis and 5-years survival rate(P0 05), but associated with histological grade and lymph-node metastasis(P

Objective To observe the effects of saponins of Panax notoginseng (PNS) on the brain energy metabolism and mitochondrial respiratory function of oxidative damaged rat model mimic to Alzheimer disease (AD). Methods Oxidative damaged rat model mimic AD (AD group) was established by injection of dihydroxy fumaric acid (DHF) and FeCl3 ADP into the left lateral ventricle of rats. The contents of adenosine triphosphate (ATP), adenosine diphosphate (ADP), adenosine monophosphate (AMP), and phosphate creatine (Pcr) in brain were determined by high performance liquid chromatography (HPLC). The mitochondrial functions (R3, R4, P/O, and OPR) were observed by Clark oxygen electrode method. The difference in the above parameters in rats in the control group (injection of saline), model group, and administration group (injection of PNS) was observed. Results The levels of ATP, Pcr, and R3, R4, P/O, and OPR of rats in AD group were significantly lower than those in the control group (0.9% NaCl instead of DHF FeCl3 ADP), but those in PNS group were higher than those in the AD group. Conclusion PNS can improve brain energy metabolism and mitochondrial function of oxidative damaged rats, suggesting that PNS could be used for the treatment of AD.

Objective To prepare gliclazide (GZ) hydroxypropyl ? cyclodextrin (HP ? CD) inclusion complexes in order to enhance its aqueous solubility. Methods Inclusion complexes, prepared using 3 different methods of spray drying, freeze drying, and grinding, were identified by phase solubility analysis, infrared spectrophotometry, thermal analysis, and determination of the limited ammonium concentration. Results The HP ? CD inclusion complexes could be prepared by using the 3 different methods. The ratio of host/guest molecules was 1∶1. Ammonium residues were detected in inclusion complexes prepared by the freeze dried method. Conclusion The inclusion complexes can be prepared by the spray drying and grinding methods. The solubility of gliclazide can be significantly increased in the inclusion complexes.

In this article routine treatment and neck acupuncture were used in 95 cases with acutecerebral embolism. The results show that the evaluation of mark with Neurological Function Distress is remarkedly reduced,and cure rate and general effective rate are more higher than routine treatment (contrast,P<0.01) .This study suggests that neck acupuncture is a simple and effective theapy of cerebral embolism.

Employed staffs in military hospital are the basic power in the development of hospital, and they are playing an im-portant role in the military medical security.The article gives a detailed elaboration on the innovation and practice of employed staff man-agement in our hospital.In order to improve the efficiency and scientific management level of employed staffs, the innovative measure-ments in employment pattern, post management, education development, policy system, promotion passage are put forward in combination with current situation of employed staff in order to promote the construction of employed staffs and the development of the hospital.

Objective To analysis the effect of salbutamol combined with noninvasive ventilator on TNF-α,IL-6,IL-8 and serum CK-MB activity in patients with chronic obstructive pulmonary disease with respiratory failure.Methods 60 patients who were diagnosed with chronic obstructive pulmonary disease with respiratory failure were collected.All patients were randomly divided into experimental group and control group,30 cases in each group. Patients in the control group received noninvasive ventilator treatment, patients in the experimental group were given salbutamol treatment on the basis of control group treatment, after the treatment, the serum levels of TNF-α,IL-6,IL-8 and serum CK-MB activity were detected in all patients.Results After treatment, compared with control group, the serum level of TNFαwas lower in the experimental group,and the difference was statistically significant(P<0.05); the serum level of IL-6 and IL-8 were lower in the experimental group(P<0.05); the serum CK-MB activity was lower in the experimental group(P<0.05).Conclusion The salbutamol combined with noninvasive ventilator can significantly reduce the serum levels of TNF-α, IL-6, IL-8 and serum CK-MB activity in patients with chronic obstructive pulmonary disease with respiratory failure, reduce the inflammatory reaction and reduce the myocardial damage,and have a guiding significance for clinica.

Total body pan & scan radiotherapeutic instrument is a special bed whose heave and the vertical slide of its bedboard are controlled by the computer. The maximum vertical travel is about 2.3 meters. To distribute equal middle plane dose in the patient's body during scanning, the doctor divides the body into four segments and gives them different lengths and velocities as required. The instrument can travel as set automatically. The reliable interlock system is involved for the maximum safety. A serial of tests prove that the instrument runs stably and the dose distribution is very uniform.
