Dried roots and rhizomes of Salvia miltiorrhiza (Danshen) are among the most commonly used traditional Chinese medicines in clinic. The material basis for its efficacy mainly includes hydrophobic tanshinones and hydrophilic salvianolic acids. The traditional effects of Danshen are "removing stasis and relieving pain, activating blood to promote menstruation, clearing heart fire and tranquilization". According to modern pharmacological studies, Danshen and its main components have cardiovascular and cerebrovascular protective effect. Recent studies showed that Danshen and its main components also demonstrated protective effects on liver injury models induced by carbon tetrachloride, D-galactosamine, acetaminophen and alcohol. In this paper, the hepatoprotective effect and mechanism of Danshen were summarized and studied.

Objective To investigate the influence factors of birth defects. Methods The congenital malformational fetuses born from 13 week of gestation to 7 days after birth were selected as the study group between April 1st, 2009 and March 31st, 2010. The health born fetuses were set as control in the same period. Case-control and the three-level of monitor network of birth defects were used in the study in the participating 75 hospitals (Qingdao Women and Children's Medical Center, Affiliated Hospital of Medical College Qingdao University, Qingdao Municipal Hospital, etc.) . The study and control group's parents were interviewed by an uniformed questionnaire which was designed specially with influence factors of birth defects. Results (1) There are 466 congenital malformational fetuses in the total of 77 231 fetuses collected in 75 hospitals. The congenital malformational rate accounts for about 6. 034‰. The top six defect diseases were congenital heart disease (112 cases) , total harelip (cleft lip; cleft lip with palate; 85 cases) ,polydactyly (53 cases) , neural tube defects (38 cases) , congenital hydrocephalus (37 cases) and limb reduction defect (27 cases) in turn, which amounts to 353 cases (54.48% , 353/648). (2) Their mother education level in the birth-defect group (25. 6%) were significantly lower than that in control group (30. 0% , P < 0. 05). (3) The rate of passive smoking, drinking, raising pets of the parents in birth-defect group were significantly higher than that in control group (P < 0. 05). (4) The rate of exposure to harmful chemical and physical factors of mothers in birth defects group (13.9% and 20. 5% , respectively) was higher than that in control group (1.1% and 11.7% , respectively) , the difference between which were significant (P < 0. 01) . The rate of disease (34. 3%) , fever (13. 1%) , taking drugs (33. 8%) in pregnancy period in birth defect group were higher than that in control group (13. 5% , 1.5% and 9. 9% ,respectively) , the difference between which were significant (P <0. 01). The rate of bad moral irritation to the mother in pregnancy in birth defect group (11. 3%) was significantly higher than that in control group (1.4% , P<0.01). (5) There were 19 cases (2.9% , 19/648) with family heredity medical history in birth defect group, but there were none in the control group, the difference between which were significant (P<0. 01). There were 89 cases (13.7% , 89/648) with unusual birth history of their mothers in birth defect group, but there were 31 cases (4. 8% , 31/650) in control group, the difference between which were significant (P<0. 01). (6) Conditional Logistic Regression model was used for univalent and multivariate analysis. The results showed that main influence factors were identified as having important effect on birth defects, including mothers' exposure to harmful chemical factors (OR=13. 46) , disease (OR=3. 37) ,taking drugs (OR=2. 20) , exposure to bad moral irritation (OR=5. 44) , food-choosy (OR=1. 90) ,anemia (OR=1. 52) in gestational period, polyembryony (OR=4. 40) , father drinking (OR=1. 55) .While it was protective factors to supplement microelements such as the calcium iron and nutrient, etc. in pregnancy period (OR=0. 45). Conclusions First, the main birth defects were congenital heart disease, total harelip (cleft lip; cleft lip with palate) , polydactyly, neural tube defects, congenital hydrocephalus and limb reduction defect in turn. Second, the main influence factors identified as having important effect on birth defects were mothers' exposure to harmful chemical factors, ill, taking drugs, exposure to bad moral irritation, food-choosy, anemia in gestational period, polyembryony, father drinking. But it is protective factors to supplement microelements such as the calcium iron and nutrient, etc. in pregnancy period. Finally, it is the important part to prevent the birth defects by reducing and controlling dangerous factors in pregnancy period.

Objective To evaluate the significance of contrast medium (CM) volume and estimated glomerular filtration rate (CM/eGFR) in predicting contrast-induced nephropathy (CIN) after PCI. Methods A total of 307 patients after PCI were enrolled from Nanfang Hospital from May 2014 to October 2015. The patients were divided into the CIN group(n = 29) and the non-CIN group(n = 278) according to whether CIN within 72 hours after PCI. The baseline renal function was assessed by the sCr and CyC, respectively. Results Twenty-nine patients (9.4%, 29/307) developed CIN. There were significant differences in Age, CM、NTpro-BNP、IABP、 Periprocedural Hypotension、Preprocedural sCr/CyC between two groups (P < 0.05, respectively). The result of multivariate logistic regression analysis showed that Age, Cardiac function ≥Ⅲ level, IABP, use CCB, CM/eGFRMDRD, CM/eGFRCyC were independent risk predictors for CIN, respectively. Receiver Operating Characteristic (ROC) curve analysis showed that the area under the curve of CM/eGFRMDRD(AUC = 0.838) was superior to CM/eGFRCyC (AUC = 0.805) without significant difference. The sensitivity and specificity were 79.3%and 76.3%(Cut-off Point = 2.094), respectively. Conclusion Both the CM/eGFRMDRD and CM/eGFRCyC may be good methods to determine maximum CM before PCI and to predict CIN after PCI currently, without significant differences between these two predictors.

Objective To evaluate laparoscopic partial splenectomy (LPS) for benign splenic tumors.Method Data of 55 patients undergoing laparoscopic partial splenectomy (20 cases) vs total splenectomy (LTS in 35 cases) at Peking University Third Hospital from August 2008 to July 2016 were collected and retrospectively analyzed.Results There was no difference in sex,BMI,preoperative H GB,preoperative PLT,operation time,operative blood loss and hospital stay between two groups.Age in LPS cases was younger than LTS group,while the tumor size was larger.On the 4th day postoperatively,PLT level was significnatly higher in LTP group.More patients in LTS group suffered from thrombocytosis.Conclusions Laprtoscopic partial splenectomy is a safe and effective procedure for the management of splenic benign tumors.

The antitussive activity assay for the root extraction of Disporum cantoniense was carried out with coughing mice induced by ammonia liquor. The results showed that the ethanol and water extractions of D. cantoniense possess strong antitussive activity, and the high dose of the former was better than positive control, and then the constituents of the ethanol extraction were separated and purified by various modern chromatographic techniques. Their structures were identified by physico-chemical properties and spectroscopic data. As a result, eight compounds were isolated and identified as stigmast-4-en-3-one(1), (22E, 24R)-ergosta-5, 7, 22-trien-3beta-ol(2), obtucarbamate A(3), obtucarbamate B(4), neotigogenin(5), azo-2, 2'-bis[Z-(2,3-dihydroxy-4-methyl-5-methoxy) phenyl ethylene] (6),dimethyl {[carbonylbis (azanediyl)] bis( 2-methyl-5, 1-phenylene) j dicarbamate (7) , and quercetin-3-O-pB-D-glucopyranoside(8). All compounds were isolated from this plant for the first time, and the result of bioactivity-directed isolation showed that compounds 3, 4, and 6 had obvious effect on antitussive activity, and compound 6 had the same level as positive control.
