ABSTRACT
ObjectiveTo understand the current situation and hot spots of research on the treatment of constipation by traditional Chinese medicine （TCM） in China and foreign countries， and provide references and directions for future research. MethodIn this study， the data analysis software CiteSpace 5.8.R3C was used to conduct bibliometrics analysis of the relevant papers on the treatment of constipation by TCM from January 1， 2000 to December 31， 2021 in China National Knowledge Infrastructure （CNKI） and Web of Science core database. The visual display was carried out. ResultAfter retrieval， 2 133 papers were included in CNKI database and 224 papers were included in Web of Science core database. The statistical analysis showed that the overall annual publication volume in China and foreign countries was on the rise， but the publication volume in China had been declining for the past two consecutive years. The author co-occurrence analysis showed that the authors with the largest number of publications in China and foreign countries were LIU Chunqiang and CHUNGWAH CHENG， respectively. The institution co-occurrence analysis showed that the institutions with the largest number of publications in China and foreign countries were the Anorectal Department of Longhua Hospital Affiliated to Shanghai University of TCM and Beijing University of Chinese Medicine， respectively. The keyword analysis showed that research in this field in China and foreign countries mainly focused on TCM therapy， clinical research， etiology and pathogenesis， etc. ConclusionThe research on the treatment of constipation by TCM is mainly concentrated in China， but there is no closely-related scientific research team. The research in this field in China and foreign countries is still developing. With the continuous deepening of research， all research institutions should pay attention to interdisciplinary intersection， highlight technological innovation， and strive to achieve greater breakthroughs in this field.
ABSTRACT
Objective:To conduct a systematic review and Meta-analysis of the efficacy and safety of Apatinib and tegafur in colonic cancer.Methods:With "Apatinib" "Tegafur" "Colonic cancer" as keywords, PubMed, Embase, Web of Science, Cochrane Library, WanFang Data, VIP, CNKI and CBM were searched from inception to December 2020 to collect randomized controlled trail about treatment for colonic cancer with Apatinib and Tegafur. Evaluated the portion remission and stable duration and progression-free survival. Meta-analysis was performed by using RevMan 5.3 software.Results:Meta-analysis showed that in colonic cancer patients, the portion remission and stable duration, tumor progression of Apatinib were not inferior to those of Tegafur ( RR=1.10, 95% CI: 0.71-1.71, P=0.640; RR=0.51, 95% CI: 0.28-1.32, P=0.205). But for progression-free survival, Apatinib was superior to Tegafur in overall patients( SMD=0.90, 95% CI: 0.42-1.37, P<0.000 1). Conclusion:In the treatment of colon cancer, compared with Tegafur, Apatinib can effectively improve the progression-free survival and has better overall survival.
ABSTRACT
Objective To evaluate the disinfect effects of glutaraldehyde, ortho-phthalaldehyde ( OPA ) and peracetic acid on gastroscopy disinfection. Methods Relevant literature from PubMed, Cochrane Library, web of science, Embase, CNKI, CBM, VIP were retrieved to collect the randomized controlled trials on disinfection by glutaraldehyde, OPA and peracetic acid on gastroscope. Literature was selected according to the inclusion and exclusion criteria. The RevMan 5. 3. 4. 0 statistic software was used to extract data and a meta-analysis was performed. Results A total of 18 RCT were included. There were significant differences in the disinfect effects between the OPA group and the glutaraldehyde group ( OR=2. 02, 95％CI:1. 88-1. 27, P<0. 00001), and between the peracetic acid group and the glutaraldehyde group ( OR = 2. 79, 95％CI:1. 52-5. 11, P = 0. 0009 ) . There were no significant differences in the disinfection effect between the OPA group and peracetic acid group ( OR=1. 30,95％CI:0. 62-2. 73, P=0. 49) . Conclusion The disinfect effects of OPA and peracetic acid are similar, which are superior to glutaraldehyde. Compared with OPA and glutaraldehyde, peracetic acid is a better choice considering its good disinfect effect and low cost.
ABSTRACT
OBJECTIVE To understand the epidemic condition on the resistant plasmids and their homology of the Staphylococcus aureus obtained from two hospitals in Gansu Province.METHODS The antibiotic sensitivity test,plasmid elimination,plasmid profile,and restriction endonuclease profile were used in analyzing the S.aureus resistant plasmids.RESULTS We isolated 15 strains of S.aureus from 196 samples in two different hospitals,the isolation rate was 7.7%.From them 86.7% isolates were resistant to the seven commonly used antibiotics in different degree.Only 13.3% strains were just resistant to one antimicrobial,the multi-resistant strains amounted for 46.7%.There were 12 isolates carried plasmids(80.0%).The results of plasmid elimination showed 11 strains carried resistant plasmids,and the one with 38 kb was a popular plasmid.The endonuclease profiles revealed that the same source strains had certain homology,there were similiar endonuclease profiles among strains in different wards.CONCLUSIONS The popular plasmids in different wards have certain homology,and they can be transferred among different strains of bacteria.
