OBJECTIVE:To establish a rapid,accurate and standardized DNA barcode identification method for the ferulic me-dicinal plants. METHODS:Genomic DNA was extracted from Ferula sinkiangensis K. M. Shen and Ferula fukanensis K. M. Shen,ITS2 sequences were amplified and sequenced,analytical similarity search method was conducted,13 species 26 samples gene ITS2 sequences of ferulic medicinal plants in GenBank database were downloaded and comparatively analyzed;interspecies and intraspecies genetic distances were calculated,and phylogenetic tree was developed for cluster analysis. RESULTS:According to calculation,species genetic distances of the 15 species ranged 0.009-0.230,average genetic distance was 0.018;results of clus-ter analysis showed DNA barcode ITS2 sequences can cluster the 32 kinds of ferulic medicinal plants into different classes. CON-CLUSIONS:The established DNA barcode ITS2 sequences identification method can accurately and rapidly identify the genuine and false samples of ferulic species.

Objective: To study the action of kangfuxin solution on the experimental gastric ulcer.Methods: The rat gastric ulcer models induced by the ligated pylorus and burned acetic acid, the gastric moucosa injury model induced by the absolute ethyl alcohol were used.Results: Kanfuxin solution possessed the protective action on the rat gastric ulcer model induced by the ligated pylorus and rat gastic mucosa injury model induced by the absolute ethyl alcohol, but didn't affect the rat gastric ulcer model induced by burned acetic acid. Conclusion: Kangfuxin Solution also has the actions of inhibiting the output of gastric acid and pepsin.

Objective To evaluate the safety and efficacy of a device that called bipolar RF (Aluma) for non-ablative treatment of facial laxity.Methods Thirty-nine Chinese volunteers of skin types Ⅲ-Ⅳ,with facial laxity and periorbital rhytides,received five times treatments at 10 days interval with Aluma RF energies (6-10 W).Standardized photographs were taken at baseline and serially for 3 months after the last treatment.The photographs were evaluated to assess the improvement in skin Iaxity by both doctors and patients.Results At 1-3 months after the last treatment,the results showed significantly subjective improvement in skin 1axity of cheek(P＜0.05),and mild to moderate Subiective improvement in skin laxity of periorbital area,nasolabial fold and upper neck.There was no serious complication.Conclusion The bipolar radiofrequency produces mild to moderate improvement of facial laxity in Chinese with no serious adverse sequelae.A high patients'satisfaction is achieved.However,further studies are necessary to demonstrate the long-term effects of the procedure and to optimize treatment parameters.

Objective A prospective randomized controlled trial was carried out to explore the best time of In-domethacin suppositories administration for the prevention of post-ERCP pancreatitis in high-risk groups. Methods 81 patients were enrolled in the study finally. Patients were randomized into group A (100 mg rectal Indomethacin suppositories was administrated immediately after ERCP), group B (100 mg rectal Indomethacin suppositories was administrated half an hour after ERCP) and group C (ERCP alone group, which did not give Indomethacin supposito-ries). The level of serum amylase, urine amylase, serum CRP, serum IL-6, serum TNF-α were measured before, 3 h, 24 h and 48 h after ERCP, and the incidence of PEP and hyperamylasemia were analyzed. Results There was 1 case (4.00%) of PEP in group A, 2 cases (5.41%) of PEP in group B and 5 cases (26.31%) of PEP in group C;the incidences of PEP of group A and group B were significant lower than that in group C (P < 0.05). There was 1 case (4.00%) of hyperamylasemia in group A, 5 cases (13.51 %) of hyperamylasemia in group B and 6 cases (31.6 %) of hyperamylasemia in group C, and the incidences of hyperamylasemia of group A and group B were significant lower than that in group C ( P< 0.05). Conclusion Administration of 100 mg Indomethacin suppositories immediately or half an hour after ERCP can effectively reduce the incidence of PEP and hyperamylasemia.

Objective To validate the value of Simplified Renal Index Score(SRI) in predicting acute renal injury requiring renal replacement therapy(RRT-AKI) after cardiac valve surgery in Chinese adult patients.Methods An analysis was conducted for all the adult patients who underwent cardiac valve surgery from January 2010 to December 2014 in Changhai Hospital,Shanghai.A total of 3 183 adult patients were included.Based on SRI Score,the patients were divided into 3 risk stages:0 to 1 point,2 to 3 point,and 4 to 8 point.The incidence of RRT-AKI was compared between different stages.And the prediction value of the SRI model was assessed by area under the receiver operating characteristic curve (AU-ROC) and the model calibration was assessed with the Hosmer-Lemeshow (H-L) test.Results After surgery 52 (1.6％) patients developed acute kidney impairment and subsequently underwent renal replacement therapy.Patients with low values of simplified renal index (0-1),medium(2-3) and high values (4 and more) were found to have increasingly higher risk for renal replacement therapy of 0.8％ (95％ CI:0.005-0.012) 、3.8％ (95％ CI:0.026-0.052) 、20％ (95％ CI:0.010-0.720),respectively.TheAU-ROCwas0.68(95％ CI:0.610-0.760,P＜0.01).The H-L test was x2 =2.45,P=0.29.Conclusion SRI model gives a certain clinical significance,suggesting that high-values patients may occur RRT-AKI with a significantly higher risk than low-values patients.However,SRI model cannot give an accurate prediction value for RRT-AKI in Chinese adult patients after cardiac valve surgery.Direct clinical use of the model should be considered cautiously.

Objective To validate the value of Cleveland Clinical Score in predicting acute renal injury requiring renal replacement therapy(RRT-AKI) after cardiac valve surgery in Chinese adult patients.Methods An analysis was conducted for all the adult patients who underwent cardiac valve surgery from January 2010 to December 2014 in Changhai Hospital,Shanghai.A total of 3 230 adult patients were included.Based on Cleveland Clinical Score,the patients were divided into 3 risk stages:0 to 2 point,3 to 5 point,and 6 to 8 point.The incidence of RRT-AKI were compared between different stages.And the predictive value of the Cleveland Clinical Score model was assessed by area under the receiver operating characteristic curve(AUC-ROC) and the model calibration was assessed using the Hosmer-Lemeshow test.The patients were also divided into two groups:Non-RRT group and RRT-AKI group.The mortality were compared between these two groups.Results The incidence of RRT-AKI was 1.67％ vs the predicted ratio of RRT-AKI 1.70％ (x2 =0.018,P =0.892).Among the stage 1,2,and 3,the actual incidence of RRT-AKI,was 1.23％,2.66％,and 16.7％ vs the predicted incidence 0.40％,1.80％,and 9.50％,respectively.The AUC-ROC for Cleveland Clinical Score predicting RRT-AKI was 0.64 [95 ％ CI(0.57,0.71),P ＜0.01].Compared with Non-RRT group,the RRT-AKI group got a higher mortality(87.00％ vs 1.50％,x2 =1 330,P ＜0.01).Conclusion The Cleveland Clinical score had no real predictive value for RRT-AKI in Chinese adult patients after cardiac valve surgery.The incidence of RRT-AKI of the whole population and the stage 3 patients could be predicted by the model.And the patients with a high Cleveland score got a higher mortality than that of patients with a low Cleveland score.
