OBJECTIVE:To optimize and improve the quality standard for Compound pediatric anticough oral solution. METH-ODS:TLC was adopted for the qualitative identification of Glycyrrhiza uralensis;chemical reaction was adopted for the qualitative identification of ipecac tincture,ammonium chloride;and HPLC was adopted for the content determination of ammonium glycyrrhi-zinate:the column was Agilent Zorbax XDB C18 with mobile phase of acetonitrile-0.2 mol/L ammonium acetate(20∶80,V/V)at a flow rate of 1.0 ml/min,the detection wavelength was 250 nm,column temperature was 30℃,and the injection volume was 10 μl. RESULTS:TLC spots of G. uralensis were clear and well-separated,negative control without interference. Differential response of ipecac tincture and ammonium chloride showed significant positive characteristics. The linear range of ammonium glycyrrhizinate was 6.08-72.96 μg/ml (r=0.999 9);RSDs of precision,stability and reproducibility tests were lower than 1.0%;recovery was 99.69%-100.28%(RSD=0.20%,n=6). CONCLUSIONS:Optimizing and improving the standard are helpful for the quality con-trol of Compound pediatric anticough oral solution.

OBJECTIVE To analyze the correlation factors of nosocomial infection in patients after receiving craniocerebral operation.METHODS Totally 388 hospitalized patients after receiving craniocerebral operation from Jan 2006 to Dec 2006 were studied retrospectively.RESULTS From them 45 pateints were suffering from nosocomial infection and total incidence of nosocomial infection was 11.59%.Among them,60.0% was lower respiratory tract infection,11.11% was surgical wound infection and 8.89% was upper respiratory infection.Aging,length of stay and invasive operation(deep vein needle detaining,trachea incision,tracheal intubation,urinary canal and drainage tube dwelling) were the main correlation tactors.CONCLUSIONS Minimizing invasive operation and early removing various kinds of dwelling tubes,using antibiotics correctly,improving hospitalizd environment and strengthening wards management are the measures to reduce nosocomial infection according its correlation factors.

Objective To study the effect of relaxation therapy on sleeping quality of patients with post cran- iocerebral traumatic syndrome. Methods 90 cases with sleep disorders were randomly divided into the treatment group and the control group. The control group was given routine care and the treatment group was given relaxation therapy combined with routine care. Take pittsburgh sleep quality index (PSQI) as evaluation criteria. Results There was significant difference between the two groups( P < 0.01 ). Sleep quality was more improved by relaxation therapy in the experimental group than that of the control group. Conclusion Relaxation therapy can effectively im- prove sleep quality in patients with post craniocerebral traumatic syndrome.

Objective To improve the sleep quality of patients by evaluating the effect of relaxation training in combination with listening to music on sleep quality of patients with intracranial aneurysm who underwent endovascular interventional therapy. Methods 55 patients who reached the entrance standard were divided into the observation group (28 cases)and the control group(27 cases).The control group received routine nursing measures. The observation group were given relaxation training in combination with listening to music based on routine nursing measures. The sleep quality was appraised by Pittsburgh Sleep Quality Index (PSQI) and patients subjective feeling was investigated by self-designed questionnaires. Results The relaxation training in combination with listening to music ameliorated the sleep quality in the observation group compared with that of the control group(P＜0.01).Conclusion The relaxation training in combination with listening to music could improved the sleep quality of patients with intracranial aneurysm who underwent endovascular interventional therapy.

Objective To prepare insulin thiolated hyaluronic acid nanoparticles (Ins-HA-Cys-NPs)and study its physicochemical properties. Methods The Ins-HA-Cys-NPs was prepared by ultrasonic emulsifying method,and the properties of nanoparticles including morphology,mean diameter,Zeta potential,entrapment efficiency and drug loading efficiency were studied,as well as the cryoprotectant selection.Results The prepared nanoparticles was round in appearance and the mean diameter was(178.5 ±0.8)nm,the polydispersity index was (0.214 ±0.013)and the Zeta potential was -(38.47 ±0.46 )mV,while the entrapment efficiency was (48.85 ±0.66 )%,drug loading efficiency was (4.79 ±0.13 )%;10%mannitol as cryoprotectant provided uniform and well dispersed suspension of nanoparticles with blue opalescence after redispersion.Conclusion The thiolated hyaluronic acid nanoparticles may be used as the carrier for oral drug delivery system of insulin,and it provides a basis for studies on rats in vivo.

Objective The biological half-life in vivo of local anesthesia is short, high concentration in local tissue is in-clined to cause central nerve and cardiovascular toxicity due to the drug absorption into blood by blood vessels.The research was to pre-pare the poly ( lactide-co-glycolide) nanoparticle loaded with ropivacaine ( RVC-PLGA-NPS) , optimize its process, and determine its characteristics in vitro. Methods An oil-in-water emulsion solvent evaporation technique was adopted to prepare the RVC-PLGA-NPS.The formulation was optimized by central composite design/response surface method(CCD-RSM), with the encapsulation effi-ciency( EE) , drug loading( DL) and particle size as the indexes.Research was also made on itsin vitro release by fitting different model equations. Results The acquired nanoparticals were smooth, with the mean particle size (331.21±2.11) nm, DL (13.81±1.35)%and EE (74.82±2.53)%.The accumulative release rate of the nanoparticals was about 73%in 96 h, which showed that Higuchi func-tion fitted the release curve. Conclusion The RVC-PLGA-NPS made by emulsion solvent evaporation technique have obvious drug-release behaviour in vitro.

Objective:To establish and improve the quality standard for Lanqiao Jiedu oral liquid. Methods:A TLC was used for the qualitative identification of Forsythiae Fructus, Sophorae Tonkinensis Radix Et Rhizoma and Anemarrhenae Rhizoma. An HPLC was used for the qualitative identification of Isatidis Radix. Forsythin in Forsythiae Fructus was quantitatively identified by HPLC. Results:Forsythiae Fructus, Sophorae Tonkinensis Radix Et Rhizoma and Anemarrhenae Rhizoma showed clear spots and there was no interfer-ence from the negative control. The HPLC further confirmed Isatidis Radix was ( R, S)- epigoitrin. Quantitative study of forsythin re-vealed good specificity without interference from the negative control. Conclusion: The study provides an improved quality standard with high specificity and reproducibility, which can be applied in the quality control of Lanqiao Jiedu oral liquid.
