Field Efficacy of Six Kinds of Fungicides for Control and Prevention of Apple Powdery Mildew(Podosphaera leucotricha)

[Objective] This study aimed to screen effective fungicide for prevention and control of apple powdery mildew. [Method] Field efficacy of six kinds of fungi- cides with 18 concentrations against apple powdery mildew was investigated. [Re- sult] 4 000-fold triflumizole WP exhibited the highest control efficacy of 82.96%, fol- lowed by 3 000-fold triflumizole WP with control efficacy of 77.75%, while 800-fold and 1 000-fold 70% thiophanate methyl WP exhibited relatively low control efficacy, which was both lower than 60%. [Conclusion] In actual production, 4 000-fold triflu- mizole WP and 3 000-fold triflumizole WP should be used alternately to control and prevent apple powdery mildew.

Study on Promoting Cabbage Growth with Diethy Amioethyl Hexanoate 5% AS

Field efficacy trials showed that Diethy Amioethyl Hexanoate 5% AS could promote growth and increase yield of cabbage. The cabbage yield increase rate was up to 40.37% by using reagent dilution 2 000 -2 500 times twice, so Diethy Diethy Amioethyl Hexanoate 5% AS is an ideal agent for regulating cabbage growth and increasing yield.

Comparison of Immune Effect of Four Commercial Marek's Disease Vaccines in Wenchang Chicken

Marek＇s disease（MD） is a lymphoproliferative disease of domestic chickens caused by a highly infectious,oncogenic alpha-herpesvirus known as Marek＇s disease virus（MDV）.The aim of this study was to compare the efficacy of four commercial MDV vaccines in Wenchang chicken.The 1-day old Wenchang chickens tested were injected with one of four different vaccines or not unvaccinated as control;five days later,they were then challenged by virulent MDV strain MD5.The results showed that,in comparison with HVT vaccines,the CVI988 vaccine gave the immunized chickens more potent immunities against challenges of MDV strain MD5.

Effectiveness and Safety of Acupoint Application of Guan Xin Su He Pill (冠心苏合丸) for Patients with Chronic Stable Angina Pectoris: A Multi-Center, Randomized Controlled Trial

Objective To assess the clinical effectiveness of acupoint application(AP)of Guan Xin Su He Pill(冠心苏合丸,GXSHP)for patients with chronic stable angina pectoris(CSAP).Methods This study was carried out in 3 local hospitals in Chengdu,China.After baseline evaluation,eligible patients were randomly assigned to the placebo application for acupoints(PAA)group or the herbal application for acupoints(HAA)group.Patients in the HAA group underwent AP with herbal powder,which was mainly GXSHP,and patients in the PAA group underwent AP with sham drugs.For each treatment session,unilateral acupoints including Neiguan(PC 6),Danzhong(RN 17),Xinshu(BL 15)and Jueyinshu(BL 14),were stimulated for both groups.AP was performed 3 times a week with a 2-day interval for 4 weeks.The primary outcome was the frequency of angina pectoris attacks per week,while the secondary outcomes included angina pain intensity measured by the Visual Analogue Scale(VAS),dose of rescue oral drugs(nitroglycerin),scores on the Seattle Angina Questionnaire(SAQ),Self-Rating Anxiety Scale scores(SAS)and Self-Rating Depression Scale scores(SDS).Clinical outcomes were measured at week 0,4 and 8.The safety of AP of GXSHP treatment for CSAP were assessed.Results A total of 121 patients were enrolled.Baseline characteristics were comparable across the 2 groups.After treatment,the angina attack numbers in the HAA group were significantly reduced from 11.00 to 4.81(P<0.05).While,for PAA group,the angina frequency was not significantly improved(baseline 10.55;post-treatment 11.05).The HAA group had significantly fewer angina attacks than the PAA group(P<0.05).Pain intensity measured by VAS in HAA group was significantly reduced from 4.06 to 3.02(P<0.05).While,for PAA group,the VAS was significantly increased(baseline 3.62;post-treatment 3.96;P<0.05).Clinical outcomes showed better improvement after treatment in the HAA group than in the PAA group in terms of oral administration of rescue drugs,SAS,SDS and SAQ scores(P<0.05).The adverse events were also reported.Conclusion AP of GXSHP is a safe and effective treatment for CSAP patients(Registration No.NCT02029118).
