Physiology of Cold Resistance of Amorpha fruticosa L. cv. Jinye

With two-year-old Amorpha fruticosa L. cv. Jinye and A. fruticosa as the research objects, the relative conductivity, MDA content, soluble sugar content, solu- ble protein content and proline content in leaf were determined during natural drop in temperature, and the SOD, POD and COD activity in leaf were determined under artificial low temperature to explore the adaptability of A. fruticosa L. cv. Jinye to low temperature. The results showed that with the decrease in natural temperature, the content of MDA in A. fruticosa L. cv. Jinye was lower than that in the control, and the contents of osmotic adjustment substances （soluble sugar, soluble protein and proline） increased, indicating that A. fruticosa L. cv. Jinye had a stronger toler- ance to low temperature compared with A. fruticosa. The activity of SOD, POD and CAT in A. fruticosa L. cv. Jinye increased continuously, higher than that in the con- trol, indicating that the resisting ability of A. fruticosa L. cv. Jinye against low tem- perature was superior to that of the control. There was no significant difference in relative conductivity between A. fruticosa L. cv. Jinye and A. fruticosa.

Effectiveness and Safety of Jinye Baidu Granules(金叶败毒颗粒)for Acute Upper Respiratory Tract Infection:A Systematic Review and Meta-analysis

To evaluate the effectiveness and safety of Jinye Baidu Granules(金叶败毒颗粒)for acute upper respiratory tract infection(AURTI).Database such as CNKI,Wan-fang,VIP,Sino Med,Web of science,Clinical Trials gov,Medline、EMBASE,CENTRAL,Cochrane Library were retrieved to collect randomized controlled trials(RCTs)on Jinye Baidu Granules(金叶败毒颗粒)in treating AURTI from the estabslishment of the database to March 2019.A total of 2 reviewers independently screened the literature according to the inclusion and exclusion criteria,and extracted material and the quality evaluation of the included studies.Quality evaluation adopted Cochrane Handbook 5.1 evaluation standards and tools.Rev Man5.3 was used to perform Meta-analysis for the adopted study.Finally a total of 4 RCTs involving 636 patients were included.Meta-analysis results showed that:compared with conventional Western medicine alone,Jinye Baidu Granules(金叶败毒颗粒)combined with Western medicine in the treatment of acute upper respiratory tract infection can improve the total effective rate of clinical efficacy[RR=0.13,95%CI(0.06,0.29),P<0.00001],shorten the time of antipyretic time for acute upper respiratory tract infection[MD=–1.22,95%CI(–1.43,–1.00),P<0.00001],shorten the time of pharyngeal pain[MD=–1.97,95%CI(–2.97,–0.96),P<0.0001]and shorten the cough disappear time[MD=–1.97,95%CI(–2.97,–0.96),P<0.0001].There were 2 papers reporting adverse reactions during the study period,and one of them specifically reported diarrhea,nausea,vomiting and stomachache in the experimental group.In the control group:diarrhea,nausea and adverse reactions disappeared after drug withdrawal;the incidence of adverse reactions was 3.92%in the control group and 5.88%in the observation group.There was no significant difference between the 2 groups(P>0.05).Based on existing data and methods,the systematic evaluation showed that,compared with Western medicine alone,Jinye Baidu Granules(金叶败毒颗粒)combined with Western medicine alone could improve the total effective rate of clinical efficacy,reduce the time of fever,sore throat,and the disappearance of cough with less adverse reactions.However,due to the low quality of the included study,large samples,multicenter,randomized,double-blind trials and trials are still needed to randomized controlled trials with reference to the CONSORT standard and the STRICTA statement.

Effects of Jinye Baidu Granule (金叶败毒颗粒) on Fetal Growth and Development with Maternal Active Human Cytomegalovirus Infection

To evaluate the effects of Jinye Baidu Granule （金叶败毒颗粒, JYBDG）, a traditional Chinese medicine compound prescription, on fetal growth and development with maternal active human cytomegalovirus infection. Methods： A prospective, randomized and controlled trial was adopted during January 1996 to June 2002. From the pregnant women with an abnormal pregnant history, 240 cases were screened to be infected by human cytomegalovirus （HCMV） by enzyme-linked immunoabsorbent assay （ELISA） and reverse transcription polymerase chain reaction （RT-PCR）. They were assigned according to the random number table to two groups. The 122 cases in the treatment group were administrated with JYBDG, one package each time, three times a day for two continuous weeks, while the other 118 in the control group did not receive any treatment. The negative conversion rate of both HCMV-IgM and HCMV late mRNA, the positive rate of HCMV-DNA in placenta and the intrauterine transmission rate between the two groups were compared, and fetal growth and development in partial fetuses were also observed. Results： The negative conversion rate of both HCMV-IgM and HCMV late mRNA, the positive rate of HCMV-DNA in placenta and the intrauterine transmission rate in the treatment group were 77. 05% （94/122）, 48.98% （48/98） and 21.74% （10/46） respectively, while those in the control group were 38. 14% （45/118）, 67.50% （54/80） and 52.63% （20/38） respectively, all showing significant difference between the two groups （P〈0.01）. Totally 35 normal infants and 11 abnormal infants were born in the treatment group, and the number in the control group was 20 and 18 respectively, and comparison between the two groups showed significant difference （P〈0.01）. Six months of child birth, the scores of both mental development index （MDI） and psychomotor development index （PDI） of infants were higher in the treatment group （20 cases） than those in the control group （20 cases）, but there was no significant difference between the two groups （P〉0.05）. Conclusion： JYBDG could decrease the intrauterine transmission of HCMV and is beneficial to fetal growth and development.

Jinye Baidu granule for wind-warmth lung-heat disease(heat in the lung-wei)： protocol for a randomized, double-blind, parallel, controlled trial

OBJECTIVE: To observe the curative effect of Jinye Baidu granule in the treatment of fever and swollen and sore throat caused by wind-warmth lung-heat disease(heat in the lung-wei) to further identify the indications.METHODS: This randomized, double-blind, parallel, controlled trial will include patients with acute upper respiratory infection and wind-warmth lung-heat disease(heat in the lung-wei). Patientswith serious bacterial infection(white blood cell count > 12 × 10~9, neutrophils > 80%) will be excluded. Patients will be divided into three categories(blocks) according to their condition: fever only, a swollen and sore throat, and combined fever plus a swollen and sore throat. Patients within each of the three blocks will be further divided into a treatment group and a control group via stratified blocked randomization. The treatment group will be treated with Jinye Baidu granule, and the control group will be treated with Fufang Shuanghua granule. The primary outcome measure will be body temperature recovery time for patients with fever, throat symptom score for patients with a swollen and sore throat, and body temperature recovery time and throat symptom score for patients with combined fever plus a swollen and sore throat. Routine blood testing, urine testing, liver function, kidney function and ECG data of all patients will be collected as safety indices before and after enrollment, and adverse events will be recorded during the whole trial course.CONCLUSION: This study protocol will include stratified block analysis according to patients' symptoms, and identify the accurate clinical indications of Jinye Baidu granule. It will also enable safety evaluation from laboratory indices and adverse events, which will provide reliable evidence for clinical treatment.

金野紫穗槐对干旱胁迫的响应

为了解金野紫穗槐在干旱胁迫下的形态、生长和生理响应特征,探明其抗旱能力,以其二年生扦插苗为试验材料、紫穗槐二年生扦插苗为对照材料,采用盆栽和持续停水的干旱处理方法,研究干旱胁迫对试验苗木生长以及渗透调节等生理指标的影响。结果表明,随着干旱胁迫时间的延长,土壤相对含水量逐渐降低,金野紫穗槐的土壤含水量下降幅度更大,30 d干旱胁迫结束时土壤重度干旱,相对含水量为24.42%。试验期间,金野紫穗槐和紫穗槐株高均持续增长、地径则先增长后降低,但株高和地径的增量均持续下降,表明干旱胁迫抑制了两个树种的株高和地径生长。两个树种的MDA和可溶性糖含量均随干旱胁迫时间延长逐渐上升;游离脯氨酸(Pro)含量金野紫穗槐呈先上升后下降趋势,紫穗槐呈持续上升趋势。结合隶属函数分析可知金野紫穗槐的抗旱性低于紫穗槐;灰色关联分析发现株高和MDA含量与抗旱性关联度最大,其次为Pro和可溶性糖含量。金野紫穗槐抗旱能力弱于紫穗槐,但在干旱胁迫下其各项指标反应良好,适合在干旱区种植,可作为优良的彩叶树种在干旱少雨地区推广应用。

金叶紫穗槐抗寒生理研究

以二年生金叶紫穗槐(Amorpha fruticosa L.cv.Jinye)和紫穗槐(对照)枝条为对象,分别测定自然降温下叶片的电导率和丙二醛、可溶性糖、可溶性蛋白、脯氨酸的含量以及人工低温下的SOD、POD、CAT活性的变化,探讨金叶紫穗槐在低温条件下的适应能力。结果表明,随着自然温度的降低,金叶紫穗槐的丙二醛含量低于对照;渗透调节物质可溶性糖、可溶性蛋白和脯氨酸含量升高,比对照有更强的低温耐受能力;SOD、POD、CAT活性持续升高,高于对照,抵御低温的能力优于对照。不过金叶紫穗槐的相对电导率与对照的差异不显著。
