This study was aimed to explore the clinical effect on treatment of climacteric syndrome by the combina-tion of Yi-Shen Yang-Xin Shu-Gan (YSYXSG) decoction and acupuncture therapy. A total of 78 female patients suffering from climacteric syndrome were selected and randomly divided into two groups, with 39 cases in each group. The control group was treated with oral administration of estradiol valerate. The treatment group was treated with the combination of YSYXSG decoction and acupuncture therapy on basis of western medicine treatment. Four-week was one treatment course. The treatment was continued for three treatment courses. Improvement state of both groups were compared by the integration of clinical symptoms before and after treatment as well as the Hamilton's Depression Scale (HAMD)/(HAMA). The results showed that according to the clinical symptoms, both groups had im-provements in varying degrees (P< 0.05, P< 0.01), in which HAMD, HAMA, FSH decreased (P< 0.05), and E2 in-creased (P< 0.05). The treatment group had more obvious superiority compared to the control group. There was sta-tistical significance between two groups (P < 0.05). The total efficiency rate of the treatment group was obviously higher than the control group with statistical significance (P < 0.05). It was concluded that combination of YSYXSG decoction, acupuncture therapy with hormonotherapy had more superiority in improving clinical symptoms, remitting emotion of anxiety-depression and controlling patient's condition compared with pure hormonotherapy, which had su-periority.

Ginsenosides,which belongs to triterpenoid saponins of plant terpenoids,are the main active components of the valuable medicinal herbs ginseng and American ginseng.Recent studies show that ginsenosides have a variety of beneficial effects,including anti-inflamatory,antioxidant,and anticancer effects.Ginsenosides are synthesized by complicated modification of triterpenoid skeleton after cyclization of 2,3-oxidosqualene through triterpene saponin synthesis pathway in which they share common early steps with phytosterols synthesis.It outlines recent advances for the biosynthesis of ginsenosides,the cloning and characterization of genes encoding key enzymes in the pathway and the basal framework of ginsenosides biosynthesis pathway.The prospects of secondary metabolism engineering in the biosynthesis of plant natural products and its application in ginsenosides biosynthesis are also discussed.

Objective:To analyze the correlation factors between peripapillary duodenal diverticulum (PDD) and choledochectasia by CT scan.Methods:The clinical data of 220 patients with duodenal diverticulum detected by multi-slice spiral CT scan and confirmed by gastrointestinal angiography or endoscopic retrograde cholangiopancreatography (ERCP) in Dahua Hospital, Xuhui District of Shanghai City were retrospectively analyzed. The correlation of the PDD, the contact of common bile duct (CBD), length of contact and exudation with choledochectasia in patients with PDD were analyzed.Results:A total of 236 duodenal diverticulum were found in 220 patients. Among them, there were 152 PDD, 41 diverticulum located superior to the duodenal papilla, 28 diverticulum located inferior to the duodenal papilla, 3 diverticulum located lateral to the duodenal papilla, and 12 diverticulumlocated in the horizontal portion. The incidence of choledochectasia in patients with PDD contacted with CBD was significantly higher than that in patients with PDD not contacted with CBD: 59.35% (73/123) vs. 37.93% (11/29), and there was statistical difference ( P<0.05); the incidence of choledochectasia in patients with contact length of PDD and CBD ≥1.5 cm was significantly higher than that in patients without contact of PDD and CBD and patients with contact length of PDD and CBD <1.5 cm: 82.43% (61/74) vs. 24.49% (12/49) and 37.93% (11/29), and there was statistical difference ( P<0.05); the incidence of choledochectasia in PDD patients with exudation was significantly higher than that in PDD patients without exudation: 10/11 vs. 52.48% (74/141), and there was statistical difference ( P<0.05). Conclusions:The patients with contact length of PDD and CBD ≥1.5 cm and patients with PDD combined with exudation could be prone to choledochectasia.

Objective To analyze the equity of health human resource allocation in public hospitals of Zhaotong city during 2008-2012,and to provide theoretical basis for the reasonable allocation of health resources.Methods The statistical description was used to analyze the number of the medical health resource,and Gini coefficient and Theli index were used to analyze the equity of health resource allocation in public hospitals of Zhaotong city.Results The amount of medical health resource showed an increasing tendency with low speed,and gaps among different areas were still existed.From 2008 to 2012,Gini coefficients of three medical health resources including the doctors,nurses and health technicians were all under 0.3.And the fluctuant tendency of the Theli Indexes and Gini coefficients were accordant with no significant increase or decrease as a whole.The combination of differences within region and difference between regions leaded to the inequity of health human resource allocation in Zhao tong city,and within region in the contribution rate of the total Theil index was greater than the difference between regions.Conclusions The quantity of health human resource is not enough in Zhaotong.The equity fluctuation of three health resources has no significatnt change.The differences within region mainly cause the inequity of health resource allocation in public hospitals of Zhao tong city.

Objective:To investigate the correlation of single nucleotide polymorphisms (SNPs) in the PRRC2A gene with the susceptibility to sporadic breast cancer among Han women in Jiangsu Province, China. Methods:Using the genotyping technique of matrix-assisted laser desorption-ionization time-of-flight mass spectrometry, we analyzed the polymorphisms of an SNP (chr6_31697494) in gene PRRC2A in 214 breast cancer patients and 212 healthy controls admitted to the Huaian Maternal and Child Health Care Hospital. The genotype frequencies were analyzed using a Chi-square test between the case and control groups. Unconditional lo-gistic regression analysis for calculating the odds ratio (OR) and 95%confidence interval (95%CI) was conducted by analyzing the cor-relation between the susceptibility to breast cancer and genotypes. Additional analysis was then performed based on the immunohisto-chemical results of the estrogen receptor (ER) and progesterone receptor (PR). Results:The genotype frequencies for chr6_31697494 between the case and control groups were not significantly different (P>0.05). Further analysis indicated that the genotype frequencies of the site were significantly different in the ER (+/-) groups or the PR (+/-) groups (P<0.05). Heterozygous genotype (chr6_31697494, CT) was related to the breast cancers with ER (+) and PR (+) (OR=0.40, 95%CI:0.33-0.47;OR=0.49, 95%CI:0.43-0.57, respectively). Conclusion:No significant difference was found between the polymorphism of chr6_31697494 in the PRRC2A gene and the suscepti-bility to breast cancer among Han women in Jiangsu Province. The heterozygous genotypes were associated with breast cancer tissues with ER (+) and PR (+).
