ABSTRACT
OBJECTIVE: The aim of this study was to investigate ziprasidone plasma concentration, daily dose and clinical efficacy and safety in Han Chinese and Mongolian patients with first-episode schizophrenia. METHODS: A total of 123 inpatients affected by schizophrenia were recruited from the Mental Health Center of Inner Mongolia in China. Ziprasidone plasma concentration, clinical efficacy and side effects were systematically evaluated at baseline, and at 1, 2, 4, and 6 weeks. Metabolic measures such as changes in weight, body mass index (BMI), fasting blood glucose (FBG), triglycerides, and cholesterol, were also recorded. RESULTS: 90 patients completed the study. Compared with Han patients, on average, Mongolian patients received a significantly higher ziprasidone dosage for adequate symptom control during the 6-week period and had a lower plasma concentration-to-dose ratio. The Mongolian patients also experienced greater increases in weight and BMI. No significant differences between the two ethnic groups were found in the rate of reduction in the Positive and Negative Syndrome Scale (PANSS) score, Treatment Emergent Symptom Scale (TESS) total score, FBG, triglycerides, cholesterol or Q-Tc interval. CONCLUSION: Compared to Han Chinese patients, Mongolian patients appeared to have increased ziprasidone clearance and require higher doses to achieve effective treatment for schizophrenia.

Objective To study the expression of retinoblastoma(Rb) protein in patients with breast cancer and its significance.Methods The expressions of Rb protein were detected in 52 patients with breast cancer,20 patients with breast fibroadenoma or breast cystic hyperplasia(control group) by S-P immunohistochemical method.(Results The negative) rate of Rb expression in breast cancer(76.91%) was higher than that in control group(15.00%)(P0.05).Of all 46 follow-up patients with breast cancer,the peritoneal recurrence and metastatic rate was 10.53% in 38 cases of the negative expression of Rb protein,and while the rate was 0 in 8 cases of the positive expression of Rb protein,there was significant difference(P
ABSTRACT
Objective To investigate the non-alkaloid constituent of Hippeastrun vittatum (Amaryllidaceae). Methods Solvent extraction and column chromatography were used to isolate the non-alkaloid constituents, and physicochemical constants and spectroscopic analysis were employed for structural elucidation. Results Five glycosphingosilipids were isolated, and their structures were elucidated to be (2S,3R, 4E, 8Z)-2-[(2R-2-hydroxyhexadecanoyl) amido ]-4, 8-octadecadiene-1, 3-diol 1-O-β-D-glucopyranoside ( Ⅰ ), (2S, 3R, 4E, 8E)-2-[(2R-2-hydroxyhexadecanoyl) amido]-4, 8-octadecadiene-1, 3-diol 1O-β-D-glucopyranoside ( Ⅱ ), (2S, 3R, 4E, 8Z)-2-[(2R-2-hydroxyoctadecanoyl) amido]-4, 8-octadecadiene-1, 3-diol 1-O-β-D-glucopyranoside (Ⅲ), (2S, 3R, 4E, 8E)-2-[(2R-2-hydroxyoctadecanoyl)amido]4, 8-octadecadiene-1, 3-diol 1-O-β-D-glucopyranoside ( Ⅳ ), (2S, 3R, 4E, 8Z)-2-[(2R-2-hydroxyeicosadecanoyl) amido]-4, 8-octadecadiene-1, 3-diol 1-O-β-D-glucopyranoside (Ⅴ), respectively. Conclusion They are all isolated from the fresh bulbs of H. vittatum for the first time.
ABSTRACT
Objective:To study the value of detection of rpsl gene mutation in streptomy cin(SM)-resistance in clinical isolates of mycobacterium tuberculosis by PCR -SSCP,and to expect to set up a r apid detective method of rpsl gene mutation in mycobacterium tuberculosis,Method Eighty seven specimens isolated from patients were detected by PCR-SSCP silver staining,and using strain H 37Rv as a control,Results In 87 mycobacterium tuberculosis clinical isolates,the r psl DNA fragments from 16 drug-susceptible isolates had no mutation in rpsL gene ,48 of 62 sputum specimens showed rpsl gene mutation by PCR-SSCP,positive rate w as 77.4%.Conclusions The rpsL gene mutation is an important molecular mechanism of M.tuberc ulosis resistance to SM.PCR-SSCP might become a rapid detecting method of SM-r esistance of M.tuberculosis.
ABSTRACT
Objective To investigate the streptomycin(SM)-resistance of Mycobacterium tuberculosis (MTB) in urine and to examine their relationships with the mutation of rspL gene. Methods 47 strains of MTB were isolated from the urine of patients with renal tuberculosis.The mutation of rspL gene were analyzed by PCR-SSCP with silver-staining,and the strains were tested for the sensitivity to streptomycin. Results All the 47 strains had positive expression of rspL gene of MTB,with 28 SM-resistant and 19 SM-sensitive.Among the 28 SM-resistence strains 19(68%) had rspL gene mutation by SSCP testing.The 19 strains of SM-sensitive had no mutation. Conclusions Detecting mutation of MTB rspL gene in urine by PCR-SSCP can rapidly and exactly identify the MTB's sensitivity to streptomycin,which is significantly important in clinical treatment of anti-tuberculosis.
