The secondary hyperparathyroidism is one of the complications of chronic renal failure (CRF) and end stage renal failure (ESRD), and becomes more serious with the development of the primary disease. Parathyroid hormone (PTH) is considered as one of the biomarks of the development of renal failure. The purpose of this article will expound the physiological effects of the PTH, the causes and clinical significances of PTH rising in CRF and ESRD patients, the determination of PTH level, and the relationships between the increase of PTH and the polymorphism of CYP2D6, GSTT1,GSTM1.

Population pharmacokinetics(PPK),which is based on the principle of statistics,can be used to estimate various inter- and intra-individual factors which affect pharmacokinetics.By using Bayesian estimator,PPK can predict individual pharmacokinetic parameters accurately.PPK is widely used in the immunosuppressive therapy with cyclosporine,tacrolimus,mycophenolic acid and sirolimus.

Objective:To explore the feasibility of pharmacy trusteeship in Shanghai medical institutions to provide useful informa-tion for the reform of medicine without added profit and pharmacy transition to clinical pharmacy. Methods: On-site investigation of seven hospitals and one famous drug retail company in Shanghai was performed combined with the communication with relative person-nel and non-random sampling questionnaire survey on the staff of pharmacy. Statwing software was used in the statistical analysis of the data. Results: A total of 93 valid questionnaires in the study were taken back. Although one hospital has achieved great progress in pharmacy trusteeship, most of respondents had negative attitudes and the common thought was that pharmacy trusteeship did more harm than good to the development of clinical pharmacy at present. Conclusion: As a consequence of drug zero interest policy and clinical pharmacy development, pharmacy trusteeship should be explored and attempted. The duties and responsibilities of all parts in pharma-cy trusteeship should be definite in law in order to standardize drug retail market and protect the interests of patient.

Objective To investigate the clinical significance of quantitation of TGF-?1 mRNA of peripheral blood mononuclear cell (PBMC) in type 2 diabetic patients at different stages of nephropathy (DN). Methods TGF-?1 mRNA transcription in PBMC was analyzed quantitatively by RT-PCR and dot blot in 93 cases of type 2 diabetic patients and 35 normal controls. Correlation of TGF-?1 mRNA in PBMC with 24 hours urinary albumin excretion rate (UAER) was also analysed. Results TGF-?1 mRNA level of PBMC in type 2 diabetic patients was significantly higher than that in normal controls (1.56?1.00 vs 1.03?0.25, P

Objective To observe the dynamic changes in collagen type Ⅰ and collagen type Ⅲ in rabbits with schistosomiasis japonica and the treatment effect of gamma interferon on the degradation of collagens in schistosomal hepatic fibrosis.Methods Each rabbit was infected with 80?1 S japonicum cercariae. Liver operations were done at different time points after infection and the liver specimens were embedded with paraffin and stained with ? SMA, HE and picric acid Sirius red. The stained slides were observed under polarizing microscope and different collagen areas calculated by computer imagine analysis system. At the 16th week after infection, the infected rabbits received a single dose of praziquantel and gamma interferon for 8 weeks.Results The area percent of collagen type Ⅰ at the 28th week after infection (40 14?17 00) increased about seven fold compared with the 8th week group (5 73?3 40). The area percent of collagen type Ⅲ at the 28th week after infection (6 80?5 19) increased about six fold compared with the 8th week group (1 15?1 34). The ? SMA positive cells also increased significantly. After gamma interferon treatment, the area percent of collagen type Ⅰ and type Ⅲ decreased significantly, from 18 51?7 52 and 4 63?3 64 (before treatment) to 3 09?1 54 and 0 40?0 37 (0 and 4 weeks after treatment) ( P

AIM　To establish an allele specific PCR amplification (ASA-PCR) for determination of the genotype of CYP2D6*10B polymorphism in Chinese subjects. METHODS　CYP2D6*10B alleles of 65 healthy Chinese subjects were analyzed by a two-step PCR assay and the correlation of genotype and phenotype was studied. RESULTS　There were 20 CYP2D6*10B heterozygous genotypes subjects (wt/m) in 35 very extensive metabolizers (VEMs), which consisted the major part of VEM subjects (57%). Meanwhile, 20 subjects consisting 69% of 29 intermediate metabolizers were CYP2D6*10B homozygous mutant genotypes (m/m). The poor metabolizer was also m/m. The metabolic ratio of CYP2D6*10B m/m subjects were larger than wt/m and wild type, the values were -1.49±0.54, -2.20±0.49 and -2.47±0.61 (P<0.01). CONCLUSION　PCR-ASA was shown to be a rapid and specific method. It can be used to study the genetic polymorphism, especially CYP2D6 intermediate metabolism.

OBJECTIVE:To investigate the cognition of clinical pharmacists on the clinical pharmacy practice and their profes-sion,and provide reference for further developing clinical pharmacy practice. METHODS:A questionnaire was designed,and ran-dom sample was conducted for the clinical pharmacists from 30 secondary and tertiary hospitals in Shanghai,and the investigation results were analyzed statistically. RESULTS:Totally 130 questionnaires were sent out,and 102 were effectively received with valid response rate of 78.46%. 94.11% of the investigated subjects were willing to be a clinical pharmacist,but 17.65% of them consid-ered that they were incompetent for their work;29.41% of them thought the current situation of clinical pharmacy practice was not ideal;all the respondents considered that the clinical pharmacist system should be implemented in medical and health institu-tions;the cognition and evaluation of investigated subjects in tertiary hospitals on clinical pharmacy practice and their profession was generally higher than those in secondary hospitals(P<0.05). CONCLUSIONS:The clinical pharmacists in medical and health institutions in Shanghai showed high cognition on their profession,and the clinical pharmacy practice has already made some achievements,but many work still need to be improved. Therefore,clinical pharmacists should continuously study their profession-al knowledge and improve their professional skills and quality;hospitals and universities should strengthen the subject construction and personnel training of clinical pharmacy and deeply carry out the clinical pharmacist system;health administration departments should strengthen the related laws and regulations of clinical pharmacy;colleges and universities should strengthen the discipline construction and personnel training.

Objective To study the synthesis and degradation of collagen at the transcription level during liver fibrosis in rabbits with schistosomiasis japonica. Methods New Zealand rabbits infected with Schistosoma japonicum cercariae were served as animal models of liver fibrosis. The liver specimens were collected through operations at 4, 6, 8, 10, 12, 16, 20, 24 and 28 weeks after infection. TypeⅠcollagen, type Ⅲ collagen, type Ⅳ collagen, MMP\|1 and MMP\|9 mRNA levels of liver tissue were detected by RT\|PCR plus dot blotting, and the size of egg granulomas and the degree of liver fibrosis were measured by histopathological examinations. Results TypeⅠcollagen, type Ⅲ collagen, type Ⅳ collagen, MMP\|1 and MMP\|9 mRNA levels increased simultaneously in the early stage after the infection, mostly reaching their peaks at 10 weeks after infection. Compared with normal controls, type Ⅰ collagen, type Ⅲ collagen, type Ⅳ collagen, MMP\|1 and MMP\|9 mRNA levels increased by 12\^0 , 11\^0 , 6\^6 , 10\^0 and 11\^0\|fold, respectively, coinciding with the changes of egg granulomas. Thereafter, both collagen and collagenase mRNA levels decreased. TypesⅠ, Ⅲ and Ⅳ collagen mRNA levels declined to 2\|fold to 3\|fold compared with normal controls ( P 0\^05) at 28 weeks. This study showed that the synthesis and degradation of collagen remained dynamic balance in the early stage of schistosomiasis, while in the later stage the metabolism of collagen synthesis was higher than that of collagen degradation. Conclusion It was confirmed at the transcription level that when the metabolism of collagen synthesis was higher than that of collagen degradation in rabbits with schistosomiasis japonica, liver fibrosis might be produced.

Objective To study the change of the content of collagen typeⅠand collagen type Ⅲ (C-Ⅰ, C-Ⅲ) in liver and spleen of patients with advanced schistosomiasis japonica. Methods Sirius red staining was used to examine pathologically the liver and spleen biopsy materials from 55 patients at the advanced stage of schistosomiasis and 5 healthy persons as control. The stained slides were observed under polarizing microscope and results were interpreted by computer imaging analysis system. (Results) The content of C-Ⅰand C-Ⅲ in liver tissue and hepatic sinusoids increased significantly in the patients than that of the control (P

Objective To construct and screen a hepatic stellate cells(HSCs) subtracted cDNA library, in order to seek differentially expressed genes in mice infected with Schistosoma japonicum. Methods HSCs were isolated from mouse as targets, and cDNA fragments of normal mouse were compared to those of S.japonicum infected mice to find differentially expressed genes by technique of suppression subtractive hybridization(SSH). Differentially expressed cDNA fragments were then directly inserted into T/A cloning vector to set up the subtractive library. Amplification of the library was carried out with transformation of DH5?. A subtracted cDNA library was constructed and then hybridized with forward and backward subtracted probes for differential screening. One hundred positive bacterial clones were randomly selected for sequencing and BLAST analysis. Finally, virtual Northern blot confirmed such differential expression. Results The amplified library contained more than 400 positive bacterial clones. Random analysis of 100 clones with restriction enzyme digestion showed that all clones contained 200-600 bp inserts. 76 ESTs were obtained with 70 related to fibrosis caused by schistosomiasis or other etiological factors. Other 6 ESTs were not found in PubMed. Conclusion The subtracted cDNA library of differentially expressed genes of HSC in normal mice and schistosome-infected mice was constructed successfully with SSH and T/A cloning techniques.
