ABSTRACT
Objective:To evaluate the efficacy of Qingpeng ointment in the treatment of early herpes zoster neuralgia.Methods:From January to June 2019, sixty patients with herpes zoster (34 males and 26 females, aged 12 to 48 years, onset time of 1 to 7 days) were randomly divided into experimental group and control group. Both groups were given the same antiviral and neurotrophic therapy after admission. The experimental group was treated with Qingpeng ointment for external use in addition. The numerical rating scale (NRS), sleep score (AIS) and adverse reactions of the two groups were evaluated at pre-treatment, 3, 5, 7, 15 and 30 days after treatment.Results:Compared with pre-treatment, the NRS and AIS scores of the experimental group were significantly reduced at each time from day 3, and the difference was statistically significant. The NRS and AIS scores of the control group were reduced at each time from day 7, and the difference was statistically significant. Compared with control group, the NRS scores of the experimental group on the 3rd, 5th, and 7th days and the AIS scores on the 3rd and 5th days after treatment were lower than those of the control group, and the difference was statistically significant. There were no serious adverse reactions in the two groups.Conclusions:External application of Qingpeng ointment can quickly relieve early neuralgia in patients with herpes zoster, improve the patients＇ sleep, and there is no obvious adverse reaction.
ABSTRACT
OBJECTIVE： To provide reference for pharmaceutical enterprises to enhance the R&D capability and improve the R&D investment strategy. METHODS： The annual report data of 13 listed pharmaceutical enterprises in southwest China were collcted. Taking fixed assets， operating costs， the number of employees in service and the amount of R&D investment as input indicators， net profit， operating income and earnings per share as output indicators， the efficiency values were calculated by using MyDEA 1.0 software based on super-efficiency DEA model. The operating efficiency of enterprises with or without R&D input were compared； the contribution rate of R&D investment to enterprises were calculated. Finally， Wilcoxon symbolic rank test was carried out by using SPSS 20.0 software to compare the difference. RESULTS： From 2013 to 2015， 10 of the 13 listed pharmaceutical enterprises had increased their R&D investment， which indicated that listed pharmaceutical enterprises in southwest China paid more attention to R&D investment. For three consecutive years， the efficiency value of R&D investment of the 13 listed pharmaceutical enterprises was significantly higher than that of the enterprises without R&D investment， and the number of the former reaching DEA efficiency was more， indicating that R&D investment was positively correlated with the operational efficiency of pharmaceutical enterprises. The Wilcoxon symbol rank test also confirmed that R&D investment was an effect input. After three enterprises joined the R&D input index， their operational efficiency was improved， and their R&D contribution was greater. Five enterprises had zero R&D contribution， their efficiency value remained unchanged whether or not they joined R&D input. The R&D contribution of other listed pharmaceutical enterprises varied greatly in each year. CONCLUSIONS： At the overall level of the industry， enterprises should increase their R&D investment and pay attention to improving R&D efficiency， establish a sound R&D innovation system and R&D personnel training mechanism， establish an integrated training mode of production， learning and research； the government should create an environment to support R&D activities of pharmaceutical enterprises. For individual enterprises， different strategies should be adopted based on practical situation in order to improve the pulling effect of R&D input on the operational efficiency of enterprises.
ABSTRACT
OBJECTIVE:To provide reference for the sustainable development of pharmaceutical enterprises in Guizhou prov-ince. METHODS:A questionnaire was conducted for 55 pharmaceutical enterprises in Guizhou province,the basic situation of en-terprises,familiarity of related directors to Good Manufacture Practice of Drugs(GMP)and relevant policy,the current situation of implementing the new version GMP were investigated and statistically analyzed,problems were found,and corresponding coun-termeasures were put forward. RESULTS & CONCLUSIONS:Totally 55 questionnaires were sent out,49 valid ones were received with effectively recovery of 85.1%. The results showed 43 enterprises(87.8%)had passed the GMP authentication;only 13 enter-prises(26.5%)directors were very familiar with the new version GMP. In terms of personnel management,the head of production management and quality management and the authorized person of quality and personnel had not yet met related requirements of the new version GMP fully;in terms of equipment and production management,production area transformation(clean areas,lounges, warehouses,water use) and air purification system design in most enterprises met related requirements of the new version GMP, 23 enterprises (46.9%) still can not conduct fully inspection to products and materials;in terms of document management,there were still some enterprises not meeting the new version GMP standards fully,enterprises'documents(health area layout,air purifi-cation layout,management procedures,operating procedures,etc.) of production site were imperfect. According to the investiga-tion,the main existing problems included lack of funds in implementing the new version GMP reform,not enough understanding or familiarity with the new version GMP,relevant personnel management not reaching the designated position,equipment and pro-duction management needing to be strengthened,document management systemic being poor,risk management being not sound, etc. It is suggested that government should give all forms of capital policy and strengthen the training of the new version GMP;en-terprises should attach great importance to the relevant personnel management,strengthen the equipment and production manage-ment,set up perfect document management system and a sound system of risk management.
ABSTRACT
OBJECTIVE:To provide reference for the sustainable development of pharmaceutical industry in Guizhou province.METHODS:By literature review,personal interview and questionnaire survey,the current situation about the development of pharmaceutical industry in Guizhou province were investigated and analyzed,and the corresponding countermeasures and suggestions were put forward.RESULTS:The literatures were obtained from network literature by Baidu search engine,published data by government portal website of administrative department,documents by CNKI and VIE Five personal interviews involved the relevant management personnel in Policies and Regulations Department,Medicine and Cosmetics Production Supervision Department,Medical Device Supervision Department of Guizhou Province Food and Drug Administration.A total of 70 questionnaires (drug production enterprises as object) were sent out,and 57 valid questionnaires were collected with the effective recovery rate of 81.4％.In the present,there were a total of 175 pharmaceutical production enterprises (56.5％ in Guiyang city) and 106 medical device manufacturers in Guizhou province.Of 57 pharmaceutical manufacturing enterprises investigated,87.8％ of them were certified by the 2010 edition of Good Manufacturing Practice (GMP).The number of varieties of Chinese herbal medicines in Guizhou province ranked second in the whole country;total area of Chinese herbal medicine planting,wild protection and tending ranked third in the whole country in 2015;the industrial output value of Chinese patent medicine accounted for 85.1％ of the total output value of the pharmaceutical industry;but no approved new medicines were class 1 and 2 new medicines;R&D personnel with high education levels took small proportion significantly.The output capacity of chemical medicine industry was far lower than the average national level;the chemical industry output value accounted for only about 10％ of the total output value of the pharmaceutical industry in the province;the rate of success approval was almost zero for new drugs declared by drug manufacturers in recent years.Biological products industry was an emerging industry,currently there were only 3 biological products production enterprises.Of 341 products in medical device industry,there were 146 class Ⅰ products,190 class Ⅱ products and 5 classⅢproducts,manifesting as narrow coverage,few production type,relatively backward level.Seven percent of pharmaceutical production enterprise involved in the derivatives industry,and the development of TCM health care industry attracted more and more attention.CONCLUSIONS:The Chinese and national medicine industry has been the dominant force,the development of chemical medicine,biological products and medical device indusmy has lagged behind,and medicine derivatives industry needs to promote the integration of TCM and health-and-fitness.Thewhole industry strategic consciousness is comparatively backward,high-end R&D personnel is lack,and independent innovation ability is weak.It is suggested to done the top design,guide enterprises mergers and restructuring;develop characteristic medicine,support small molecule chemical medicines and biological products enterprises deeply;deepen the understanding of industrial policy,and increase investment in independent innovation;develop new medicine derivatives,and expand the pharmaceutical e-commerce sales channel;broaden the industry chain depth,breadth and width,and excavate medical big data.
ABSTRACT
The inverse cancer comorbidity in schizophrenia patients may be related to the genetic factors ,involving the regu‐lation of apoptosis .The tumour suppressor gene TP53 ,involved in neural apoptosis ,is one of the potential candidate genes associat‐ed with schizophrenia which might reduce colorectal cancer risk .We recruited 270 schizophrenia patients and 312 colorectal cancer patients without schizophrenia .To examine the genetic association between schizophrenia and colorectal cancer ,we analysed eight SNPs (rs12951053 ,rs1625895 ,rs2909430 ,rs9895829 ,rs1042522 ,rs8079544 ,rs8064946 ,rs17806770) covering 14 .35 kb in the re‐gion of TP53 .We observed that one of the eight genetic polymorphisms showed statistically significant differences between the colo‐rectal cancer subjects and the schizophrenia subjects (rs12951053 ,P=0 .000 1 ,OR 1 .70 ,95% CI 1 .30-2 .23) .In addition ,the hap‐lotype of A‐G (rs12951053‐rs8064946) ,giving a global P=0 .001 8 ,was the most significant .Our data indicate that the polymor‐phisms of rs12951053 in TP53 confer reduced susceptibility to colorectal cancer and suggest a potential protective mechanism a‐gainst colorectal cancer in the schizophrenia patients of Han Chinese origin .
ABSTRACT
<p><b>BACKGROUND</b>We evaluated the impact of the number of metastatic lymph nodes and the metastatic lymph nodes ratio (the ratio between metastatic lymph nodes and total dissected lymph nodes, MLNR) in patients with gastric adenocarcinoma following curative gastrectomy and also analyzed the relationship between the number of removed lymph nodes and prognosis in node-negative gastric cancer.</p><p><b>METHODS</b>From January 2005 to December 2010, 1 390 patients who were diagnosed with gastric adenocarcinoma and underwent curative gastrectomy were included. In particular, lymph node metastasis was not present in 515 patients. The number of metastatic lymph nodes and the metastatic lymph nodes ratio were selected for univariate and multivariate analyses to evaluate their influences on the disease outcome. The survival curve was presented according to the number of removed lymph nodes in node-negative gastric cancer using Kaplan-Meier plots.</p><p><b>RESULTS</b>The overall 5-year survival rate was 54% in this group. Univariate analysis revealed that age category, macroscopic appearance, histological grade, tumor size, depth of primary tumor invasion, number of metastatic lymph nodes, metastatic lymph nodes ratio, tumor, nodes, metastasis-classification (TNM) stage and status of lymphovascular, and vessel invasion have significant impact on survival. The number of metastatic lymph nodes and the metastatic lymph nodes ratio both have significant impact on survival (P < 0.001). However, in multivariate analyses, only the metastatic lymph nodes ratio was identified to be an independent prognostic factor (P < 0.001). The number of removed lymph nodes in node-negative was a strong prognostic factor of survival, the more lymph nodes dissected, the better the survival.</p><p><b>CONCLUSIONS</b>The metastatic lymph nodes ratio has more significant prognostic value for survival in patients with gastric cancer following curative gastrectomy than the number of metastatic lymph nodes. The number of removed lymph nodes might be an important prognostic factor for gastric cancer without lymph node metastasis.</p>
