OBJECTIVE: To establish the HPLC method for the determination of chloramphenicol and dapsone in compound chloramphenicol cream. METHODS: The analytical column was Hypersil ODS and the mobile phase consisted of 0.1%sodium heptanesulfonate solution (a mixture of 0.1% sodium heptanesulfonate 500 mL and dimethylformamide 5 mL plus acetic acid glacial 0.5 mL)-acetonitrile (75∶25) at a flow rate of 1.0 mL?min-1. The detection wavelength was 272 nm and the sample size was 20 ?L. RESULTS: The linear ranges of chloramphenicol and dapsone were 25.59～153.54 ?g?mL-1 (r=0.999 9) and 12.57～75.42 ?g?mL-1 (r=0.999 9), respectively. The average recovery rates were 100.62% (RSD=0.92%) and 100.93% (RSD=1.22%), respectively. CONCLUSION: The method is simple and accurate and can be used for the quality control of compound chloramphenicol cream.

Objective To establish clonal human embryonic stem cell lines and investigate their biological characteristics. Methods Cells were derived from one inner cell mass of human blastocyst, multiplied for 20 passages, and then dissociated into single cell suspension by digestion with 0.5% trypsin. Single cell was picked up and plated into individual well of a 96-well plate containing feeder-layers directly under a dissection microscope. The outgrowth clones were passed by treatment with collagenase. Surface markers were detected by cytochemistry and histoimmunochemistry. Karyotypes were tested using standard G-banding techniques. The pluripotency was analyzed by inoculating cells into severe combined immunodeficient (SCID) mice. Results Two clonal human embryonic stem cell lines were established. Cells of these two lines possess the characteristics and differentiating potencies: normal 46 XX karyotypes; expressing a series of surface markers such as: alkaline phosphotase, stage-specific embryonic antigen (SSEA)-4, tumor recognition antigen (TRA)-1-60, TRA-1-81 etc; and forming teratomas comprising derivatives of three embryonic germ layers such as neural tissue, cartilage, squamous epithelium and columlar epithelium when injected into SCID mice. Conclusions The two single cell-cloned human embryonic stem (hES) cell lines were derived in our laboratory. The cells possess stable biological characteristics of undifferentiated hES cells.

Objective:To study the effect of cervical canal mucosa dng excision on cervical columnar eversion in Loop electrosurgical excision procedure(LEEP).Methods:A prospective randomized control trail was performed in 125 cervical intraepithelial neoplasia(CIN)patients.Cervix and cervical canal were conically excised with triangle electrode in 62 patients in the control group;in the study group,a small ring electrode was put into the cervical canal and the cervical canal mucosa was excised about 0.5～0.8cm,after excision as the control group.Follow-up was performed postoperatively in 1,3,6 months respectively.The operation time,the bleeding volume,the rate of cervical columnar eversion and cervical adhesion or stenosis were compared between the two groups.Results:The rate of cervical columnar eversion in the study group (1/63,1.59%)was lower than that in the control group(9/62,14.52%).There was significantly statistical difference between them(P=0.008).There was no statistical differences between them in the operation time,the bleeding volume,and the rate of cervical adhesion or stenosis (P>0.05).Conclusions:The cervical canal mucosa ring excision in LEEP can effectively prevent postoperative cervical columnar eversion.

Objective To test the reliability and validity of the Chinese version of Quality-of-Life Questionnaire for Mechanically Ventilated Patients (QOL-MV). Methods The English version of QOL-MV was revised and translated into Chinese version. The reliability and validity of the Chinese version of QOL-MV was tested in 120 mechanically ventilated patients. Results The Cronbachαcoefficient of the Chinese QOL-MV was 0.904. The item-level content validity index of Chinese QOL-MV were 0.86-1.00 and the scale-level content validity index of Chinese QOL-MV was 0.92. Two factors were extracted by factor analysis and the cumulated variance was 80.18%. The dimensional factor loading of each item was greater than 0.565. The correlation coefficient between the score of Chinese QOL-MV and the Euroqol Group′s 5-domain 3 Level Questionnaire (EQ-5D) and Richards Campbell Sleep Questionnaire (RCSQ) was 0.947 and 0.561 respectively (P<0.01). Conclusions The Chinese version of QOL-MV has been proved to be reliable and valid.It can be used to measure the quality-of-life for mechanically ventilated patients.

Objective:To evaluate the effect of clinical pharmacists in the continued therapy of stroke patients .Methods:Totally 146 cases were selected and randomly divided into the observation group and the control group according to the standard matching meth -od.The observation group was treated with the continued therapy .The control group was given one-month telephone follow-up after the discharge.The differences in the drug compliance (Morisky scale), systolic blood pressure (SBP), diastolic blood pressure (DBP), glycosylated hemoglobin (HbA1C), serum total cholesterol ( TC), low density lipoprotein ( LDL-C), health behaviors ( HPLPⅡscale) and relapse rate were compared between the two groups in the 3rd, 6th and 12th month after the discharge.Results:The differ-ences in the above indices were statistically significant between the two groups ( P <0.05) at the various time points , and those were more significant with time extending (P<0.01).The difference of the relapse rate in the 3rd, 6th and 12th month after the discharge between the two groups were significant .Conclusion: Clinical pharmacists can improve the drug compliance and health behaviors of stroke patients and reduce the relapse rate .It is worthy to be recommended in clinics .

Objective To study the brain development in infants of diabetic mother. Methods The development of cerebral grey matters and white matters was evaluated in 64 infants of pregnant diabetic mother by echoencephalography and medical image analysis system. The parameters were compared with 101 infants of non-diabetic mother. The early brain response function of newborns was assessed. The neurodevelopment after neonatal period was also evaluated. Results The brain in infants of diabetic mathers was immature.The average values of grey density in thalami (76.92?6.60) were significantly lower in full term infants of diabetic mathers than that of the infants of non-diabetic mathers (84.72?6.35). These were also obvious in white matters of frontal lobe [(62.68?5.21) vs (67.60?4.09)] and occipital lobe [(73.39?5.67) vs (78.61?2.95)] (P

Objective To understand the spectroscopic property of AO-H2SO4-KBrO3-naphthol system and the enhanced mechanism of resonance light scattering(RLS),and to develop a method for the determination of trace naphthols in urine.Methods In the dilute H2SO4 medium,naphthols could react with KBrO3 and AO to form ion-association complexes,which produced a new RLS spectrum and resulted in the great enhancement of RLS.The characteristics of RLS spectrum,three-dimensions fluorescence spectrum,absorption spectrum and fluorescence spectrum and the optimum conditions of reaction were studied.Results The enhanced intensity of RLS was 468 nm.The linear range was at 1.41?10-7-2.80?10-5 mol/L for ?-naphthol,1.28?10-7-3.00?10-5 mol/L for ?-naphthol.The relative coefficient and the limits were 0.999 6 and 0.422?10-7 mol/L,0.999 3 and 0.385?10-7 mol/L for ?-naphthol and ?-naphthol,respectively.The urine samples analysis of the relative standard deviation was 4.8%-7.3% and the average recovery rate was 90.7%(n=6).Conclusion This method is sensitive,simple,rapid and applicable to the determination of trace naphthols in human urine.
