This study is to investigate the sedative and hypnotic effects of a novel compound H1208. The sedative activity of H1208 was investigated by recording the spontaneous locomotor activity of mice. The hypnotic property was evaluated by the latency and duration of sleep (loss of righting reflex) in mice and the effect of hypnotics on sleep pattern of electroencephalogram were studied in conscious, freely moving mice with chronically implanted electrodes. The brain monoamine neurotransmitters levels in mice were measured by high performance liquid chromatography-electrochemical detection. The spontaneous locomotor activity was decreased by 56.7% and 80.2% in H1208 (5 and 25 mg x kg(-1), ip) treated mice, respectively. The loss of righting reflex was directly induced in mice after H1208 (60 mg x kg(-1), ip) administration. The non-rapid eye movement sleep increased significantly by 131% and 259%, respectively, within 3 hours after H1208 (30 and 60 mg x kg(-1), ip) administration. However, the rapid eye movement sleep decreased significantly. The contents of DA in the striatum and cortex and 5-HT in the cortex decreased significantly. These results demonstrated that H1208 has potent sedative and hypnotic effects, which may be closely related to the decreased contents of DA and 5-HT in mouse brain.

Chlorogenic acid displays several important roles in the therapeutic properties of many herbs, such as antioxidant activity, antibacterial, antiviral, scavenging free radicals and exciting central nervous system. Only about one-third of chlorogenic acid was absorbed in its prototype, therefore, its gut metabolites play a more important role in the therapeutic properties of chlorogenic acid. It is necessary to consider not only the bioactivities of chlorogenic acid but also its gut metabolites. This review focuses on the potential activities and mechanisms of chlorogenic acid and its gut metabolites on central nervous system diseases.

OBJECTIVE To discuss the characteristics and risk factors of nosocomial infection inpatients with chronic kidney disease.METHODS The data from chronic kidney disease(CKD) patients retrospectively analyzed.RESULTS The nosocomial infection rate of CKD patients was 14.73%,urinary tract was the most comun site,The main-pathogens were Gram-negative bacteria,and then Gram-positive bacteria and fungii.The patients with diabetic nephropathy,lupus nephritis,aging,lower glomerular filtration rate,hypoproteinemia,anemia,and long time duration were easy to get nosocomial infection.CONCLUSIONS Nosocomial infection in CKD patients is related to underlying diseases,age,kidney function,serum albumin level,hemoglobin level,duration time in the hospital.

OBJECTIVE To discuss the clinical traits,pathogenesis and TCM stepwise treatments of fungal urinary tract infection.METHODS According to the risk factors and clinical character of fungal urinary tract infection,we clarified the mechanism of the disease.The principal aspect was spleen-kidney vacuity detriment and the secondary incidental was accumulated damp-heat and static blood in the lower burner,viz weaken healthy qi and excessive pathogenic factor.Hence during the clinical treatment we should regulate faculty condition.In the acute infection period we should give priority to dispel evils supplemented by the recovery of right qi.In the convalescence we should pay more attention to support right supplemented by dispelling.RESULTS The most common pathogen of fungal urinary tract infection was Candida albicans.The TCM stepwise treatments of fungal urinary tract infection together with regulatiy entire faculty condition had the characteristics of high efficacy and few side effects.CONCLUSIONS The TCM stepwise treatments of fungal urinary tract infection has more potentiality which deserves further study.

OBJECTIVE To study the situation of nosocomial infection of maintenance hemodialysis of chronic renal failure patients and discuss the risk factors and preventive measures.METHODS Retrospective analysis of our hospital clinical data in hemodialysis patients with nosocomial infection from Jan 2005 to Dec 2006 was taken.RESULTS There were 44 nosocomial infection cases from 89 cases.The infection rate was 49.43%.Hemodialysis patients were high-risk population of the nosocomial infection.The common infection site was the respiratory tract(52.27%),followed by central venous catheter-related infections(25.00%),urinary tract infections(15.91%) and intestinal infections(6.82%).The primary diseases of diabetic nephropathy,serious anemia,low albumin and elderly were the risk factors(P

BACKGROUND:Conventional rehabilitation evaluation call not provide more objective data for analysis,so all innovative method to monitor rehabilitation of the cervical spine is introduced.OBJECTIVE:The monitoring rehabilitation system of the cervical spine develops independently under Visual Basic 6.0 environment.It can gather both video and photos at dynamic and static states.According to the suitable feature points of the video,the system could calculate characteristic parameters,such as moving angles,distances,speed,acceleration,and integral curves.Thus,the system could create patients'database.RESULTS:The system could calculate different kinds of patients'characteristic parameters through data recording.Through the objective comparison of characteristic parameters,the turning flexibility of head and controlling capability for head turning could be reflected.CONCLUSl0N:The design is an innovation in the monitoring rehabilitation systems of the cervical spine.It makes up the shortcomings of conventional rehabilitation evaluation and objectively reflects the rehabilitation status of patients.

Twelve flavonoids were isolated from an ethanol extract of Machilus wangchiana by a combination of various chromatographic techniques including column chromatography over silica gel and Sephadex LH-20 and reversed-phase flash chromatography and HPLC. Their structures were identified by spectroscopic data analysis (IR, MS, and NMR) as (+)-catechin (1), (-)-epicatechin (2), 3'-O-methyl-(+)-catechin (3), 3'-O-methyl-(-)-epicatechin (4), 3, 5, 7, 2', 5'-pentahydroxy flavan (5), (-)-naringenin (6), (-)-eriodictyol (7), (-)-liquiritigenin (8), (2R,3R)-(+)-dihydrokaempferol (9), (2R,3S)-(-)-dihydro- kaempferol (10), (2R, 3R)-(+)-taxifolin (11), and quercetin (12). Compounds 1-10 are isolated from the genus Machilus for the first time.

OBJECTIVE To discuss the clinical traits,pathogenesis and traditional Chinese medicine(TCM) stepwise treatments of the patients who suffered from pulmonary infection after kidney transplantation.METHODS Because of patients after kidney transplantation easily suffered from pulmonary infection,which was characterized by non-typical symptoms,concealment and varity.In the aspects of the pathogenesis of this disease,the principal aspect of which was the weakened body resistance(kidney deficiency)and the secondary incidental was affected pathogenic factor(heat,toxin,stasis brewing in the lungs),viz weaken healthy qi and excessive pathogenic factor.Hence during the clinical treatment we should attach importance to regulate entire faculty condition.Considering the acute attack stage and restoration stage,we would differently inflict therapies of clearing heat,resolving toxin,quickening the blood,supplementing the kidney and nourishing yin,clearing heat and moistening the lung and so on,according to differentiation of symptoms and signs,in which way we could give attention to both the root and tip.RESULTS The TCM stepwise therapy of pulmonary infection after kidney transplantation had the characteristics of high efficacy,few side reactions and stable long-term curative effects.CONCLUSIONS The TCM therapy of pulmonary infection after kidney transplantation has more potentiality and predominance,which deserves further study.
