Mesenchymal stem cells (MSCs) are multipotent stem cells existing in multi-organs and can differentiate into several kinds of somatic cells. Recently it has been found that MSCs, under defined conditions in vivo or in vitro, can be induced to trans-differentiate into islet-like cells, which can secrete a small amount of insulin and lower blood glucose levels in diabetic mice. Thus, two major obstacles of islet transplantation, the insufficience of donor islets and immunologic rejection, might be solved simultaneously with this technique. This finding provides a new insight into treatment for diabetes.

Multivariate logistic regression showed that independent risk factors included age, ascites, MODS. ConclusionsIn case of severe acute pancreatitis,the independent risk factors related to mortality were age, ascites and MODS.

OBJECTIVE: To study the association of the vitamin D receptor gene BSM Ⅰ, TAQ Ⅰ and APA Ⅰ genetic polymorphisms with bone mineral density and biochemical markers of bone turnover in postmenopausal women.METHODS: ①total of 576 postmenopausal Han ethnic women of 48-84 (62.17±6.37) years old in Fuzhou city were investigated, on the basis of their informed consent, through random sampling method from January 2007 to December 2008. ②The subjects were recorded regarding to their age, menopause duration, body mineral index and postmenopausal fracture incidence. ③Dual energy X-ray absorptiometry was used for measuring the bone mineral density of vertebrae L<,2-4>, left femoral neck, trochanter and Ward's triangle. ④The genetic polymorphisms of vitamin D receptor gene BSM Ⅰ, TAQ Ⅰ and APA Ⅰ were detected using polymerase chain reaction-rastriction and fragment length polymorphism (PCR-RFLP) technique. ⑤The biochemical markers of bone turnover (serum bone gla protein, serum bone alkaline phosphatase, urinary pyddinoline and urinary deoxypyridinoline) were detected with enzyme linked immunosorbent assay.RESULTS: A total of 561 subjects up to standard were involved in the result analysis. ①There was no significant difference in bone mineral density among genotypes of vitamin D receptor gene BSM Ⅰ, TAQ Ⅰ and APA Ⅰ polymorphisms (P > 0.05). ②There was no significant difference in the biochemical markers of bone tumover among genotypes of BSM Ⅰ, TAQ Ⅰ and APA Ⅰ polymorphisms (P > 0.05). ③There was no significant difference in the incidence of osteoporosis among genotypes of BSM Ⅰ, TAQ Ⅰ and APA Ⅰ polymorphisms (P > 0.05). ④There was no significant difference in the incidence of postmenopausal fracture among genotypes of BSM Ⅰ, TAQ Ⅰ and APA Ⅰ polymorphisms (P > 0,05).CONCLUSION: BSM Ⅰ, TAQ Ⅰ and APA Ⅰ polymorphisms of the vitamin D receptor gene are not obviously associated with osteoporesis in postmenopausal women, and accordingly can not be taken as genetic markers of osteoporosis in postmenopausal women in Fuzhou.

Objective To investigate the correlation between bone mineral density(BMD)and the PXh haplotype combining estrogen receptor (ER) gene Xba Ⅰ , Pvu Ⅱ polymorphisms and osteocalcin gene Hind Ⅲ polymorphism in postmenopausal women.Methods In 307 subjects,the BMD of lumbar vertebrae and proximal femur were measured by dual energy X-ray absorptiometry and the Xba Ⅰ and Pvu Ⅱ polymorphisms of ER gene and the Hind Ⅲ potymorphism of osteocalcin gene were detected by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP).Results (1)The BMD of greater trochanter was significantly lower in XX genotype group than in xx genotype group ( P<0.05).The BMD of femoral neck, greater trochanter and Ward's triangle were lower in Xx genotype group[(0.695±0.087)g/cm2 , (0.592±0.106)g/cm2, (0.500±0.115) g/cm2] and X allele group[(0.697±0.088)g/cm2 , (0.594±0.105)g/cm2, (0.505±0.123)g/cm2] than in xx genotype group[(0.737±0.108) g/cm2,(0.653±0.119)g/cm2 ,(0.554±0.130)g/cM2] and non-X allele group[(0.737 ± 0.108) g/CM2, (0.653 ± 0.119) g/cm2 , (0.554 ± 0.130) g/cm2] ,respectively (all P<0.05 ).(2)The BMD of Ward's triangle was lower in PP genotype group and P allele group than in pp genotype group and non-P allele group (P<0.05).(3)The BMD of femoral neck, greater trochanter and Ward's triangle were lower in hh genotype group and h allele group than in I-IH genotype group, and were lower in non-h allele group than in HH genotype group(all P<0.05).(4)Women carrying PX, PXh haplotypes combining ER gene and osteocalcin gene had lower BMD at femoral neck than those not carrying PX,not carrying PXh haplotypes, respectively (all P<0.05).ConclusionsER gene(Xba Ⅰ) polymorphism and osteocalein gene(Hind Ⅲ) polymorphism are associated with BMD in postmenopausal women.The presence of X allele or h allele　shows negative influence on the BMD of postmenopausal women.The PXh haplotype is a suitable　genetic marker of postmenopausal women osteoporosis in Fuzhou area.

BACKGROUND:Studies have shown the bone mineral density of postmenopausal women is closely related to parathyroid hormone. But there are differences in different areas.
OBJECTIVE:To investigate the association between BstBⅠ polymorphism of parathyroid hormone gene with bone mineral density in postmenopausal women from Fuzhou area.
METHODS:The bone mineral densities of the lumbar spine, femoral neck, trochanter and Ward’s triangle were measured in 150 postmenopausal women by dual energy X-ray absorptiometry. The genotype of parathyroid hormone gene was determined by polymerase chain reaction-restriction fragment length polymorphism.
RESULTS AND CONCLUSION:(1) The distribution of parathyroid hormone genotypes were BB genotype 68.8%, Bb 24.1%, and bb 7.1%. The B al elic gene frequencies reached 81%, while b was 19%. The distribution fol owed the Hardy-Weinberg equilibrium. (2) Analysis of the relationship between the genotypes and bone mineral density:There was no significant difference in the bone mineral densities of the lumbar spine, femur, neck, trochanter and Ward’s triangle among the three genotypes (P>0.05). BstBⅠ gene polymorphism of parathyroid hormone gene is not correlated to bone mineral density, and there is no enough evidence to support genotype of parathyroid hormone gene as a genetic marker in predicting the risk of developing osteoperosis in Fuzhou postmenopausal women.

Objective To describe the status of breast reconstruction patients′decision regret, self-efficacy and satisfaction with information in the preoperative period, and discuss the correlation among them. Methods Four instruments were used to investigate 100 breast reconstruction patients in one tertiary hospital in Guangzhou, including participants′ personal profile, Decision Regret Scale, Modified Stanford Self-Efficacy Scale and the subscale of Information Satisfaction of Breast Reconstruction-Questionnaire. Results The mean score of Decision Regret Scale was (10.8 ± 2.5)points in breast reconstruction patients, and the minority of patients experienced decision regret (30%, 30/100). The mean score of self-efficacy and satisfaction with information in the preoperative period were (6.6±1.9) and (2.9± 0.6) points. The study also found that decision regret was negatively correlated with self-efficacy and satisfaction with information in the preoperative period (P < 0.01). Conclusions Totally 30 percent of patients experienced decision regret to undergo breast reconstruction. However, patients who had lower levels of self-efficacy and satisfaction with information in the preoperative period were at greater risk to experience decision regret to undergo breast reconstruction. The results may assist health care professionals to provide appropriate psychological support, care and information.

OBJECTIVETo investigate the effect of estrogen (E2), progesterone(P4), and paclitaxel (taxol) on the growth of primary human ovarian cancer cells in vitro and the expression of Drosha.

METHODSHuman ovarian cancer cells were treated with estrogen, progesterone or in combination with paclitaxel in vitro. The inhibition rate of ovarian cancer cells was assessed by methyl thiazolyl tetrazolium (MTT) assay. Apoptosis rate and cell cycle were determined by FACS analysis. The relative abundence of Drosha expression was detected by real-time quantitative PCR (qRT-PCR) and Western blotting.

RESULTSThe inhibition rate of the estrogen group, progesterone group, paclitaxel group, E2(+)Taxol group, P4(+)Taxol group was (31.53 ± 8.21)%, (25.22 ± 15.50)%, (46.71 ± 4.25)%, (69.46 ± 3.71)%, and (47.35 ± 39.02)%, respectively, significantly higher than that of the control group (0%, P<0.05 for all). Relative to the ER (-) in ovarian cancer cells,Drosha mRNA expression level of estrogen group, progesterone group, paclitaxel group, E2(+) Taxol group,and P4(+)Taxol group was 1.62 ± 0.10,1.60 ± 0.10,1.75 ± 0.16,1.95 ± 0.20, and 1.53 ± 0.06, respectively, significantly higher than that of the control group (1.00, P<0.05 for all). Relative to the ER (+)in ovarian cancer cells,the Drosha mRNA expression level of estrogen group, progesterone group, paclitaxel group, E2(+)taxol group, and P4(+)Taxol group was 1.03 ± 0.14, 1.60 ± 0.09, 1.75 ± 0.16, 1.60 ± 0.10, 1.53 ± 0.06, respectively except estrogen group, significantly higher than that of the control group (1.00, P<0.05). Relative to the ER (-) in ovarian cancer cells, the Drosha protein expression levels of the control group, estrogen group, progesterone group, paclitaxel group, E2(+) taxol group, and P4(+) Taxol group were 0.25 ± 0.05, 0.87 ± 0.30, 0.85 ± 0.38, 1.30 ± 0.21, 1.75 ± 0.83, 1.62 ± 0.82, respectively, with a significant difference between the experimental groups and the control group (P<0.05). Relative to the ER(+)ovarian cancer cells, the Drosha protein expression levels in the estrogen group, progesterone group, paclitaxel group, E2(+) taxol group, and P4(+) taxol group, were 0.28 ± 0.16, 0.85 ± 0.38, 1.30 ± 0.21, 0.94 ± 0.18, and 1.62 ± 0.82, respectively except estrogen group, significantly higher than that of the control group (0.25 ± 0.05, P<0.05 for all).

CONCLUSIONSEstrogen and progesterone in combination with paclitaxel can inhibit the growth of human ovarian cancer cells in vitro, and affect the cell apoptosis rate. Estrogen and taxol can alter the cell cycle. Estrogen and progesterone combined with paclitaxel show tumor suppressing or sensitizing effect through upregulated Drosha expression, and are associated with the estrogen receptor expression.
