OBJECTIVE:To provide the basis for the formulation of the health intervention strategy for medical and health insti-tutions'pharmacists and provide reference for other related research. METHODS:A total of 180 medical and health institutions' pharmacists in Heilongjiang province were investigated and evaluated by work satisfaction MMSS scale(modified)and quality of life(SF-36)scale,and the relevant data were analyzed statistically. RESULTS:A total of 180 questionnaires were distributed and 134 valid questionnaires were collected. The effective recovery rate was 74.44%. The average score of work satisfaction degree was (3.44±0.79),which was at the middle level. The highest score was the relationship with colleagues and the lowest score was wel-fare. The physical function,the physiological function and the social function dimension of the respondents were higher thanChi-nese norm. The scores of physical pain,general health,vitality,emotional function and mental health were lower thanChinese norm,and there was statistical significance between the scores of the other dimensions andChinese norm(P<0.05),except for the physiological function and vitality dimension. Multivariate analysis showed that gender,duties,education,length of service and work satisfaction score had an effect on quality of life(P<0.05),among these factors,work satisfaction score was positively correlated with quality of life. CONCLUSIONS:The quality of life of medical and health institutions'pharmacists still needs to be improved,which is related to many influential factors,and job satisfaction is an important influential factor.

Objective To analyze the long-term prognosis and prognostic factors of idiopathic collapsing focal segmental glomerulosclerosis (FSGS) and not otherwise specified FSGS in children. Methods The clinical, pathology and follow-up data of patients with idiopathic collapsing FSGS and not otherwise specified FSGS were analyzed retrospectively by Kaplan-Meier method, univariate and multivariate Cox regression analysis. Results A total of 64 patients (29 idiopathic collapsing FSGS and 35 not otherwise specified FSGS) were diagnosed by renal biopsy. The 4-year renal survival rate of idiopathic collapsing FSGS and not otherwise specified FSGS were 48.3%, 74.3% respectively. Univariate analysis revealed that the renal survival time were 25.41±3.28 months in idiopathic collapsing patients, and 35.53±2.73 months in not otherwise specified patients. The different is significant (χ2=4.07,P=0.044). Multivariate Cox regression analysis showed that poor treatment response (HR=5.92, P<0.05) and renal insufficiency at early stage (HR=2.45, P<0.05) were independent risk factors of prognosis. Conclusions Compared with patients with not otherwise specified FSGS, the renal survival time is shorter in idiopathic collapsing FSGS patients. Patients with renal insufficiency and poor response to treatment have poorer prognosis.

Objective To investigate the association of PGC-1 α gene single nucleotide polymorphisms (SNPs) with type 2 diabetes mellitus in Southern China Han population. Methods 350 patients with type 2 diabetes mellitus and their parents and 366 normal Han volunteers were recruited in the study. Their blood specimens were collected to extract the genornic DNA. Thr394Thr(G/A), Gly482Ser(G/A), Thr528Thr(A/G) and Thr612Met (C/T) genotypes were identified by PCR-RFLP and DNA direct sequencing. The possible association was analyzed between diabetic patients with the specific cSNPs and their haplotypes by case-control and haplotype relative risk (HRR) and transmission disequilibrium test (TDT) methods. Results (1) The case- control study indicated that G and A allele frequencies of PGC-1 α gene Gly482Ser variant were 0.589, 0.411 in type 2 diabetic group and 0.687, 0.313 in normal group respectively (X<'2> = 15.076, P < 0.01). The allele frequencies of Thr394Thr, Thr528Thr, Thr612Met polymorphisms did not show significant difference between twogroups respectively (all P > 0.05). The distributions of Thr394Thr-Gly482Ser-Thr528Thr haplotypes in the diabetic group were significanly different from the controls (X<'2> = 40.2, P < 0.05) and had a linkage disequilibrium with type 2 diabetes mellitus (t = 2.503, P < 0.05). (2) The family-basod studies showed that 482A allele was transmitted more significantly both via TDT and extended TDT from heterozygous parents to patients than expected respectively (all P < 0.05). HRR also supported that the 482A allele was more often transmitted to patients than predicted by chance (X<'2> = 7.217, P = 0.007, HRR = 1. 450). TDT analyses of haplotypes suggested that the frequencies of 394A-482A-528A-612C,394A-482A-528A-612T, 394A-482A-528G-612C and 394A-482A-528G- 612T haplotypes significantly deviated from 0.5 (P < 0.05 or P < 0.01). Conclusion In Southern China Hanpopulation, type 2 diabetes mellitus is associated with the Gly482Ser variant of PGC-1α gene, and Thr394Thr (G/ A) variant of PGC-1α gene appears to play an auxiliary role in this association.

Objective To determine the random spot albuminuria to creatinine ratio (ACR) of normal pregnant women , to track the pregnancy outcome , and to discuss the predictive value of ACR in women with hy-pertensive disorders complicating pregnancy (HDCP). Methods Except for 87 pregnant women suffering from HDCP, 2 038 pregnant women were enrolled in this study. ACR, routine examinations of blood and urine, blood biochemical, 24-hr urinary protein were determined. Results ACR, but not 24-hr urinary protein level,was sig-nificantly higher in women with HDCP. There was positive correlation between the ACR and 24-hr urinary protein quantitation. Age, gestational weeks, ACR, red blood cells, fasting plasma glucose, serum creatinine, total pro-tein were the independent risk factors for HDCP. The sensitivity , specificity and optimal cut off value of ACR for predicting HDCP were 0.78, 0.63, 1.46 mg/mmol. Conclusions There was positive correlation between ACR and 24-hr urinary protein quantitation , and ACR provided a more sensitive pathway for early predictionof HDCP.

Purpose To explore the significance of three-dimensional reconstruction of fetus based on MRI scan data. Materials and Methods Three woman (more than 39 weeks' gestation) with a strong wish to have natural childbirth and voluntary to take the examination in Nanfang Hospital of Southern Medical University were recruited in the study. Mimics 10.01 software was used to do three-dimensional reconstruction. Results The fetal surface tissue showed low signal on the two-dimensional images, and amniotic fluid and lung, bladder, cerebrospinal fluid showed high signal. The placenta and uterine wall showed moderate to low signal. Those contributed to the clear boundary between fetal surface and other tissue surround. The three-dimensional fetus models were reconstructed successfully, which clearly demonstrated the main surface features and spatial position of the fetus. The fetal morphology and fetal position could be viewed in various directions. Conclusion Fetus surface can be reconstructed into three-dimensional model based on MRI data set, which has advantage of large visual field and can be observed at arbitrary angle. It provides a new method for morphological analysis and prenatal evaluation for fetal development and growth.
10.Discussion and analysis on point "Siguan".
Chinese Acupuncture & Moxibustion 2005;25(5):340-342
Point "Siguan" is seen in the Miraculous Pivot: Jiuzhen Shieryuan for the first time. From then on the doctors of every dynasties cited point "Siguan" and explained its content. But the authors hold that their explanations do not conform with the meaning in the Huangdi's Internal Classic. Therefore, the authors put forward their explanations for point "Siguan" and indicate that correct understanding of point "Siguan" is very important for treatment of diseases of five-zang organs.
