Objective Viral encephalitis is an infectious disease severely affecting human health.It is caused by a wide variety of viral pathogens,including herpes viruses,flaviviruses,enteroviruses,and other viruses.The laboratory diagnosis of viral encephalitis is a worldwide challenge.Recently,high-throughput sequencing technology has provided new tools for diagnosing central nervous system infections.Thus,In this study,we established a multipathogen detection platform for viral encephalitis based on amplicon sequencing. Methods We designed nine pairs of specific polymerase chain reaction(PCR)primers for the 12 viruses by reviewing the relevant literature.The detection ability of the primers was verified by software simulation and the detection of known positive samples.Amplicon sequencing was used to validate the samples,and consistency was compared with Sanger sequencing. Results The results showed that the target sequences of various pathogens were obtained at a coverage depth level greater than 20×,and the sequence lengths were consistent with the sizes of the predicted amplicons.The sequences were verified using the National Center for Biotechnology Information BLAST,and all results were consistent with the results of Sanger sequencing. Conclusion Amplicon-based high-throughput sequencing technology is feasible as a supplementary method for the pathogenic detection of viral encephalitis.It is also a useful tool for the high-volume screening of clinical samples.

RNA editing, an essential post-transcriptional reaction occurring in double-stranded RNA (dsRNA), generates informational diversity in the transcriptome and proteome. In mammals, the main type of RNA editing is the conversion of adenosine to inosine (A-to-I), processed by adenosine deaminases acting on the RNAs (ADARs) family, and interpreted as guanosine during nucleotide base-pairing. It has been reported that millions of nucleotide sites in human transcriptome undergo A-to-I editing events, catalyzed by the primarily responsible enzyme, ADAR1. In hematological malignancies including myeloid/lymphocytic leukemia and multiple myeloma, dysregulation of ADAR1 directly impacts the A-to-I editing states occurring in coding regions, non-coding regions, and immature miRNA precursors. Subsequently, aberrant A-to-I editing states result in altered molecular events, such as protein-coding sequence changes, intron retention, alternative splicing, and miRNA biogenesis inhibition. As a vital factor of the generation and stemness maintenance in leukemia stem cells (LSCs), disordered RNA editing drives the chaos of molecular regulatory network and ultimately promotes the cell proliferation, apoptosis inhibition and drug resistance. At present, novel drugs designed to target RNA editing(e.g., rebecsinib) are under development and have achieved outstanding results in animal experiments. Compared with traditional antitumor drugs, epigenetic antitumor drugs are expected to overcome the shackle of drug resistance and recurrence in hematological malignancies, and provide new treatment options for patients. This review summarized the recent advances in the regulation mechanism of ADAR1-mediated RNA editing events in hematologic malignancies, and further discussed the medical potential and clinical application of ADAR1.

Objective To explore the influence of Buqi Qingchang Decoction(composed of Buzhong Yiqi Decoction plus Baitouweng Decoction with Curcumae Radix and Curcumae Longae Rhizoma added)combined with XELOX chemotherapy and Bevacizumab targeted therapy on the clinical efficacy,quality of life and survival period of patients with metastatic colorectal cancer of qi deficiency and damp-heat syndrome.Methods A retrospective study was conducted in 70 patients with metastatic colorectal cancer of qi deficiency and damp-heat syndrome who were admitted to the Department of Oncology,Chongqing Hospital of the First Affiliated Hospital of Guangzhou University of Chinese Medicine(Chongqing Beibei District Hospital of Traditional Chinese Medicine)from December 2020 to December 2023.The patients were divided into an observation group and a control group according to the therapy,with 35 cases in each group.The control group was treated with XELOX chemotherapy combined with Bevacizumab targeted therapy,while the observation group was given oral administration of Buqi Qingchang Decoction together with chemotherapy and targeted therapy.The changes in the serum levels of tumor markers such as carcinoembryonic antigen(CEA)and carbohydrate antigen 199(CA199),and Karnofsky Performance Status(KPS)scores for quality of life in the two groups were observed before and after treatment.Moreover,the clinical efficacy,progression-free survival(PFS)and overall survival(OS)were compared between the two groups.Results(1)After treatment,the objective response rate(ORR)and disease control rate(DCR)in the observation group were 51.42％(18/35)and 85.71％(30/35),respectively,which were significantly higher than those in the control group[25.71％(9/35)and 54.29％(19/35),respectively],and the differences between the two groups were statistically significant(P＜0.05 or P＜0.01).(2)The PFS of the observation group was 16.7 months and that of the control group was 12.9 months,and the OS of the observation group was 23.3 months and that of the control group was 17.7 months.The PFS and OS of the observation group were significantly longer than those of the control group,and the differences were statistically significant(P＜0.05 or P＜0.01).(3)After treatment,the levels of serum CEA and CA199 in the two groups were significantly decreased compared with those before treatment(P＜0.05),and the KPS scores were significantly increased compared with those before treatment(P＜0.05).The decrease of serum CEA and CA1 99 levels and the increase of KPS scores in the observation group were superior to those in the control group,and the differences were statistically significant(P＜0.05).Conclusion XELOX chemotherapy and Bevacizumab regimen combined with Buqi Qingchang Decoction exerts certain effect in treating metastatic colorectal cancer.The combined therapy is effective on enhancing the efficacy to a certain extent,prolonging the survival period of patients,reducing the risk of disease progression,decreasing the levels of serum tumor markers,and improving the quality of life of patients.

OBJECTIVE To clarify the core content of traditional Chinese medicine （TCM） policy in the provinces of China， so as to provide reference for optimizing the structure of the policy system of traditional Chinese medicine in China and assisting the inheritance and innovation of TCM industry in various regions. METHODS The websites of directly affiliated organs in 31 provinces， excluding Hong Kong， Macao and Taiwan， were retrieved to collect the TCM policies released from 2000 to 2021. The importance of keywords in the TCM policies of each province was measured based on term frequency-inverse documentation frequency （TF-IDF） keyword extraction method， and the similarities and differences were analyzed among TCM policies. RESULTS & CONCLUSIONS A total of 99 documents related to TCM policies of various provinces were obtained in this study， most of which were released after 2016. The theme of national TCM policy covered four aspects： building TCM talent team， perfecting TCM service system， strengthening TCM resource management and promoting TCM industry innovation. The TF-IDF values of “medical institutions”“traditional Chinese medicine”“medical treatment” were higher than other keywords in each province， indicating that the provinces paid more attention to the construction of TCM service system and the management of TCM resources than other aspects. Anhui and Jiangsu， Beijing and Henan， Hubei and Jilin， Hubei and Tianjin， and Hubei and Yunnan had the more degree of similarity in TCM policies， which all contained 16 of the same keywords. Therefore， the above regions should be encouraged to strengthen exchanges and cooperation and realize mutual promotion and joint development. Among all the keywords whose importance ratio was greater than 0.2，“ Tibetan medicine” was unique to Qinghai and Tibet，“ disease type” was unique to Guangdong， and the TF-IDF value of “supervision and management” in Beijing was higher， indicating that the emphasis of TCM policy formulation in different provinces was various. Meanwhile， the top 10 keywords of TF- IDF value in all provinces did not have words related to financial input， and the TF-IDF values of “informatization” in most provinces did not rank at the top. It is suggested to increase financial input or encourage social financing， and add “Internet+new business” in the field of TCM.

OBJECTIVES: To construct a clinical prediction model for the impact of acupuncture on pregnancy outcomes in poor ovarian response (POR) patients, providing insights and methods for predicting pregnancy outcomes in POR patients undergoing acupuncture treatment. METHODS: Clinical data of 268 POR patients (2 cases were eliminated) primarily treated with "thirteen needle acupuncture for Tiaojing Cuyun (regulating menstruation and promoting pregnancy)" was collected from the international patient registry platform of acupuncture moxibustion (IPRPAM) from September 19, 2017 to April 30, 2023, involving 24 clinical centers including Acupuncture-Moxibustion Hospital of China Academy of Chinese Medical Sciences. LASSO and univariate Cox regression were used to screen factors influencing pregnancy outcomes, and a multivariate Cox regression model was established based on the screening results. The best model was selected using the Akaike information criterion (AIC), and a nomogram for clinical pregnancy prediction was constructed. The prediction model was evaluated using receiver operating characteristic (ROC) curves and calibration curves, and internal validation was performed using the Bootstrap method. RESULTS: (1) Age, level of anti-Müllerian hormone (AMH), and total treatment numbers of acupuncture were independent predictors of pregnancy outcomes in POR patients receiving acupuncture (P<0.05). (2) The AIC value of the best subset-Cox multivariate model (560.6) was the smallest, indicating it as the optimal model. (3) The areas under curve (AUCs) of the clinical prediction model after 6, 12, 24, and 36 months treatment were 0.627, 0.719, 0.770, and 0.766, respectively, and in the validation group, they were 0.620, 0.704, 0.759, and 0.765, indicating good discrimination and repeatability of the prediction model. (4) The calibration curve showed that the prediction curve of the clinical prediction model was close to the ideal model's prediction curve, indicating good calibration of the prediction model. CONCLUSIONS The clinical prediction model for the impact of acupuncture on pregnancy outcomes in POR patients based on the IPRPAM platform has good clinical application value and provides insights into predicting pregnancy outcomes in POR patients undergoing acupuncture treatment.

It is a cross-sectional study, a total of 1 680 patients with allergic rhinitis and/or asthma diagnosed at the Department of Allergic Reaction of Shanxi Bethune Hospital from July 2021 to June 2023 who underwent allergen sIgE testing and/or skin prick test were retrospectively enrolled.There were 772 males and 908 females.The age range was 3 to 88 years. The median age was 35 years.There were 108 cases in the child group (≤12 years old), 102 cases in the adolescent group (13-17 years old), 819 cases in the youth group (18-40 years old), 498 cases in the middle-aged group (41-65 years old), and 153 cases in the elderly group (>65 years old). There were 333 cases in the allergic rhinitis group, 827 cases in the allergic asthma group, and 520 cases in the allergic rhinitis with asthma group. There were 1 254 urban patients and 426 rural patients.There were 253 cases in the northern Shanxi region, 1 195 cases in the central Shanxi region, and 232 cases in the southern Shanxi region. Statistical analyses were performed using the χ ² test or Fisher's exact probability method to compare the differences in allergen sIgE positivity rates by sex, age, disease, living environment, and geography. The results showed that 1 027 patients (61.1%) were positive for at least one allergen sIgE, with Artemisia having the highest rate of positivity (603/1 680, 35.9%), followed by ragweed (302/1 680, 18.0%) and dust mite combinations (245/1 680, 14.6%). The number of individuals with single-allergen sIgE positivity was 357 (357/1 027, 34.8%), with the highest number of single-allergen sIgE positive results associated with Artemisia (114/357, 31.9%). The number of multiple-allergen sIgE positive results was 670 cases (670/1 027, 65.2%), with the highest number of patients having 2 allergen sIgE positive results (243/670, 36.3%). The overall positivity rate for allergen sIgE was significantly higher among males than among females (65.7% vs. 57.3%, χ²=12.405, P<0.001). Overall positivity for inhalant allergen sIgE was higher in the child and adolescent groups (88.0% vs. 88.2% vs. 59.8% vs. 40.2% vs. 19.0%, χ²=223.372, P<0.001), and food allergen sIgE positivity was highest in the child group (54.6% vs. 36.3% vs. 26.0% vs. 18.9% vs. 21.6%,χ²=66.383,P<0.001). The sIgE positivity rate of inhalant allergens was significantly higher in the allergic rhinitis group and the allergic rhinitis with asthma group than in the allergic asthma group, except for cockroaches and molds (P<0.05). The overall positive rate of allergen sIgE was significantly higher among urban patients than among rural patients (66.2% vs. 46.2%, χ²=53.230, P<0.001). The difference in the overall positive rate of allergen sIgE among patients from different regions was not statistically significant (56.1% vs. 62.0% vs. 62.1%, χ²=3.140, P=0.208). The sIgE positivity of dust mite combinations was significantly higher in the central Shanxi region and the southern Shanxi region than in the northern Shanxi region (15.5% vs. 18.1% vs. 7.1%,χ²=14.411, P=0.001). In conclusion, artemisia was the most important sensitizer for respiratory allergic diseases in Shanxi Province. The types of allergens and positivity rates were different for different sexes, ages, diseases, living environments, and regions. Therefore, patients with allergic diseases should be tested for allergens to help with the diagnosis, treatment and prevention of allergic diseases.
