ABSTRACT
@#Objective Through bibliometrics and visual analysis of the related studies on traditional Chinese medicine (TCM) treatment of immune thrombocytopenia (ITP), this study aims to sort out the overall research progress, hotspots, and trends in this field, and provide reference for further research in ITP. Methods The articles on ITP treated by TCM were retrieved from China National Knowledge Infrastructure (CNKI), Wanfang Database, China Science and Technology Journal Database (VIP), Web of Science Core Collection (WOSCC), and PubMed. The retrieval time was from the establishment of the databases to July 31, 2022. VOSviewer, CiteSpace, Carrot2, and NoteExpress were used for data analysis of the articles in terms of their quantities, types, and journals, and for visualization of research hotspots, authors, institutions, and keywords. Results 1 493 Chinese articles and 40 English articles were included. The articles in Chinese mainly focus on clinical trial research and clinical experience summary, while the English articles mainly focus on clinical trial research and animal research. The Chinese articles were published in 317 Chinese journals, while English articles were published in 29 English journals. Research hotspots include the clinical syndrome differentiation of ITP, the therapeutic effect of TCM compounds on ITP, and the mechanism of ITP treatment. Keyword analysis shows that there are many research achievements in integrated traditional Chinese and western medicine treatment, clinical research, famous doctors’ experience, TCM treatment, cellular immunity, and humoral immunity. The authors with the most articles in Chinese and English are Professor CHEN Xinyi and Professor MA Rou, respectively, and the research institutions with the most articles are Dongzhimen Hospital of Beijing University of Chinese Medicine and Xiyuan Hospital of China Academy of Chinese Medical Sciences. Chinese herbs often used to treat ITP clinically include Xianhecao (Agrimoniae Herba), Nvzhenzi (Ligustri Lucidi Fructus), Mohanlian (Ecliptae Herba), Zhongjiefeng (Sarcandrae Herba), etc., and the prescription usually used to treat ITP include Guipi Decoction (归脾汤), Xijiao Dihuang Decoction (犀角地黄汤), Bazhen Decoction (八珍汤), Erzhi Pill (二至丸), and Xiaochaihu Decoction (小柴胡汤). The main development trends toward retrospective study, TCM treatment mechanism, and data mining. Conclusion The research on TCM treatment of ITP has progressed steadily, but in-depth studies and close cooperation between research institutions are necessary for the modernization of TCM in treating ITP.
ABSTRACT
Objective:Both antibiotic resistant bacteria (ARBs) and antibiotic resistant genes (ARGs) are considered as one of the most dangerous environmental pollutants in the 21st century by the WHO. This study aims to understand the ARGs of Klebsiella pneumoniae (K. pneumoniae) with multiple drug resistance bacterium from the marine water collected from a beach at Sanya Bay, and to explore the antibiotic resistance mechanism of the K. pneumoniae, providing a basis for exploring the transfer of drug resistance genes of beach, and preventing and controlling the health risk of entertainment population.Methods:The sample of marine water were collected and screened by Mcconkey plate. The drug sensitive test was detected by Merieux VITEK2, The DNA was extracted and one strain of 16srDNA was sequenced and identified as K. pneumoniae. Whole-genome resequencing was performed using Illumina HiseqXten platform, and the obtained sequences were compared with NCBI blasting. The reference bacterium were multi-resistant K. pneumoniae HS11286. Plasmids were extracted and the resistant genes were identified.Results:The ARGs encoding protein was 117/4801 (identity > 40%) and the carrying rate was 2.436 9%. The identity of following ARGs of OKPB, sul1, rpoB, ef-tu, phoP, sul2, AAC(6’)-ib-cr, QnrB, floR, aadA16 were more than 99%. The strain showed resistance to ampicillin, ticacillin/clavulanic acid and chloramphenicol, and was intermediate to ampicillin/sulbactam, compound sulfamethoxazole, ciprofloxacin, minocycline. Preliminary positioning showed that Qnrs, sul1, tetA, cat, QacE were carried on plasmid.Conclusion:The multiple drug resistant bacteria strain has a variety of different resistant phenotypes, some ARGs can be easily spread by plasmid. It probably will bring exposure risk to people for entertainment. Sensibility of some antibiotics were on the brink of resistance, It is necessary to tracking corresponding antibiotics pollution and strengthening monitoring of ARBs and mobile resistant elements of bacteria.

ABSTRACT
Objective To explore the correlation of circRNAs' expression level to the negative-and positive symptoms of patients with schizophrenia (SZ).Methods Gene chip screening was performed with the peripheral blood samples from each five of SZ patients and normal controls.Nine circRNAs showing differentiate expression were confirmed,and further verification was done by real-time fluorescence quantitative PCR in 102 SZ patients and 103 normal controls.All the SZ patients were assessed with Positive and Negative Symptom Scale (PANSS).Results It was revealed that the expression levels of circRNA_102101,circRNA_102315,circRNA_104597,circRNA_101835 and circRNA_101836 were significantly down-regulated (P＜0.01 or P＜0.05),and circRNA_103102 and circRNA_103704 were up-regulated in SZ group (P＜0.01).The ACT value of circRNA_102101 and circRNA_103102 was positively correlated to the positive symptoms (P＜0.01 or P＜0.05),and the ACT value of circRNA_103704 also showed positive correlation with positive symptoms and general psychopathological symptoms (P＜0.01 or P＜0.05).The ACT values of circRNA_102101,circRNA_103102,circRNA_102315,circRNA_103704 and circRNA_102802 were correlated with thinking disorder (P＜0.01 or P＜0.05),and the ACT values of circRNA_102101,circRNA_103102,circRNA_104597,circRNA_103704 and circRNA_102802 were correlated with the activation (P＜0.01 or P＜0.05).The ACT values of circRNA_102101,circRNA_103102,circRNA_103704 and circRNA_102802 were positively correlated with paranoid (P＜0.01 or P＜0.05),and of circRNA_102101,circRNA_103102,circRNA_103704 and circRNA_102802 were markedly correlated with assault (P＜0.01 or P＜0.05).Therefore,circRNA_103704 was chosen into regressive equation of positive symptoms (P＜0.01),and circRNA_103704 and circRNA_102315 were chosen into regressive equation of general pathological findings (P＜0.01 or P＜0.05).Conclusion The expression levels of circRNA_103704 and circRNA_103102 are obviously up-regulated in SZ patients than in normal controls,and markedly correlated with the negative and positive SZ symptoms,so might be the dominant regulatory factors in the pathological process of schizophrenia.
ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the enhancing effects of ginsenoside Rg3 combined with mitomycin C and tegafur (MF) on postoperative chemotherapy in advanced gastric cancer.</p><p><b>METHODS</b>Seventy-one postoperative patients with advanced gastric cancer were randomly divided into two groups, the control group (n=33), which received treatment with only MF (Mitomycin C+Tegafur), and the trial group (n=38), which were treated with ginsenoside Rg3+MF. The serum VEGF levels in the control group and trial group were detected preoperatively and postoperatively, meanwhile, the serum VEGF levels in 30 healthy persons were detected as comparison. The relations between patients survival and serum VEGF levels were analyzed.</p><p><b>RESULTS</b>The levels of serum VEGF in advanced gastric cancer were higher than those in healthy persons [(297.8+/-129.6) pg/ml vs (212.3+/-67.5) pg/ml] (P<0.01), and were correlated with the depth of tumor invasion, lymph node metastasis, tumor size > 4 cm and TNM stage (P<0.05). Fourteen weeks after operation, the levels of serum VEGF in trial group decreased below those of preoperation and approached to normal range, while in the control group, the levels of serum VEGF decreased near those of preoperation only. The median survival of patients in trial group and control group were 40 and 25 months respectively. The survival rate of patients in trial group was significantly higher than that in control group (P=0.047).</p><p><b>CONCLUSION</b>The combined application of ginsenoside Rg3+MF chemotherapy can decrease the concentration of serum VEGF and improve the survival rate in advanced gastric cancer patients.</p>
