ObjectiveTo provide a reference for the rational clinical use of cold Chinese medicines by sorting and analyzing their properties， flavors， meridian tropism， primary therapeutic indications， methods of administration， dosages， and precautions as recorded in the 2020 edition of Pharmacopoeia of the People's Republic of China （Chinese Pharmacopoeia）. MethodsCold Chinese medicines for internal and external use included in the 2020 edition of Chinese Pharmacopoeia were entered one by one， and their efficacy， properties， flavors， meridian tropism， methods of administration， dosages， and usage precautions were statistically classified and summarized to guide clinical medication use. ResultsA total of 259 cold Chinese medicines for internal use were included and categorized into 18 efficacy groups， mainly comprising heat-clearing drugs， water-excreting and dampness-draining drugs， and phlegm-resolving， cough- and asthma-relieving drugs. Their predominant flavors were bitter， sweet， and pungent， and they primarily entered the liver， lung， and stomach meridians. The main methods of administration included decocting first， grinding into powder for oral use， or preparing into pills or powders， with most dosages ranging from 9 to 15 g. A total of 83 cold Chinese medicines for external use were included， involving 16 efficacy categories. Their main flavors were bitter， sweet， and pungent， primarily entering the liver， lung， and large intestine meridians. The main external application methods were grinding into powder for topical use or preparing decoctions for fumigation and washing， with most dosages ranging from 9 to 15 g. Whether for internal or external use， cold Chinese medicines should be used with caution or contraindicated in pregnant women. ConclusionThe cold Chinese medicines included in the 2020 edition of the Chinese Pharmacopoeia are mainly suitable for patients with carbuncles， swellings， and coughs. However， in clinical practice， it is necessary to strictly follow the principles of syndrome differentiation and treatment， pay attention to administration methods and dosages， and use cold medicines rationally and effectively to improve clinical efficacy.

Objective To optimize the platelet enrichment method,and to analyze the concentration changes of key molecules in platelet-rich plasma(PRP)before and after activation,as well as the impact of its activated products on the proliferation of rat endothelial progenitor cells.Methods The tube double-centrifu-gation method was employed to optimize platelet enrichment,and the platelet count in the enriched PRP was measured.ELISA was used to detect the concentration changes of vascular endothelial growth factor(VEGF),endostatin(ES),and P-selectin(CD62P)in PRP before and after activation.The PRP was activated by using liquid nitrogen freeze-thaw method,and the effect of its activated products on the proliferation of rat endothelial progenitor cells was evaluated by using the methyl thiazolyl tetrazolium(MTT)assay.Results The optimal enrichment coefficient of platelets achieved by the double-centrifugation method was 4.63.After low-speed,long-duration double centrifugation,the platelet count was highest in the upper layer of the buffy coat.For PRP with a platelet count of 500× 109/L obtained by machine collection,the VEGF con-centrations before and after activation were(3 418.12±488.80)pg/mL and(4 530.04±308.30)pg/mL,re-spectively,the ES concentrations were(6 168.98±253.22)pg/mL and(6 594.65±82.47)pg/mL,respec-tively,the CD62P concentrations were(6 678.23±324.15)pg/mL and(17 630.53±746.24)pg/mL,respec-tively,statistically significant differences were observed in the above indicators before and after activation(P＜0.01).The activated PRP was diluted in a gradient manner by using a specialized culture medium for en-dothelial progenitor cells.MTT assay results indicated that,in the basal medium,the optimal volume fraction for promoting endothelial progenitor cell proliferation was 0.25％after 48 hours of culture;in the complete medium,the optimal volume fractions for promoting endothelial progenitor cell proliferation were 0.062 5％after 24 hours and 0.125％after 48 hours.Conclusion The concentrations of VEGF,ES,and CD62P in the optimized,enriched PRP exhibited significant changes before and after activation.The optimal volume fraction for promoting endothelial progenitor cell proliferation in the basal medium was 0.25％.

Objective:To evaluate the accuracy of the oral healthcare information provided by different large language models (LLM) to explore their feasibility and limitations in the application of oral auxiliary, treatment and health consultation.Methods:This study designed eight items comprising 47 questions in total related to the diagnosis and treatment of oral diseases [to assess the performance of LLM as an artificial intelligence (AI) medical assistant], and five items comprising 35 questions in total about oral health consultations (to assess the performance of LLM as a simulated doctor). These questions were answered individually by the five LLM models (Erine Bot, HuatuoGPT, Tongyi Qianwen, iFlytek Spark, ChatGPT). Two attending physicians with more than 5 years of experience independently rated the responses using the 3C criteria (correct, clear, concise), and the consistency between the raters was assessed using the Spearman rank correlation coefficient, and the Kruskal-Wallis test and Dunn post hoc test were used to assess the statistical differences between the models. Additionally, this study used 600 questions from the 2023 dental licensing examination to evaluate the time taken to answer, scores, and accuracy of each model.Results:As an AI medical assistant, LLM can assist doctors in diagnosis and treatment decision-making, with an inter-evaluator Spearman coefficient of 0.505 ( P<0.01). As a simulated doctor, LLM can carry out patient popularization, with an inter-evaluator Spearman coefficient of 0.533 ( P<0.01). The 3C scores of each model as an AI medical assistant and a simulated doctor were respectively: 2.00 (1.00, 3.00) and 2.00 (2.00, 3.00) points of Erine Bot, 1.00 (1.00, 2.00) and 2.00 (1.00, 2.00) points of HuatuoGPT, 2.00 (1.00, 2.00) and 2.00 (1.00, 3.00) points of Tongyi Qianwen, 2.00 (1.00, 2.00) and 2.00 (1.75, 2.25) points of iFlytek Spark, 3.00 (2.00, 3.00) and 3.00 (2.00, 3.00) points of ChatGPT (full score of 4 points). The Kruskal-Wallis test results showed that, as an AI medical assistant or a simulated doctor, there were statistically differences in the 3C scores among the five large language models (all P<0.001). The average score of the 5 LLMs on the dental licensing examination was 370.2, with an accuracy rate of 61.7% (370.2/600) and a time consumption of 94.6 min. Specifically, Erine Bot took 115 min, scored 363 points with an accuracy rate of 60.5% (363/600), HuatuoGPT took 224 min and scored 305 points with an accuracy rate of 50.8% (305/600), Tongyi Qianwen took 43 min, scored 438 points with an accuracy rate of 73.0% (438/600), iFlytek Spark took 32 min, scored 364 points with an accuracy rate of 60.7% (364/600), and ChatGPT took 59 min, scored 381 points with an accuracy rate of 63.5% (381/600). Conclusions:Based on the evaluation of LLM′s dual roles as an AI medical assistant and a simulated doctor, ChatGPT performes the best, with basically correct, clear and concise answers, followed by Erine Bot, Tongyi Qianwen and iFlytek Spark, with HuatuoGPT lagging behind significantly. In the dental licensing examination, all the 4 LLM, except for HuatuoGPT, reach the passing level, and the time consumpution for answering is significantly reduced compared to the 8 h required for the exam regulations in all of the five models. LLM has the feasibility of application in oral auxiliary, treatment and health consultation, and it can help both doctors and patients obtain medical information quickly. Howere, their outputs carry a risk of errors (since the 3C scoring results do not reach the full marks), so prudent judgment should be exercised when using them.

OBJECTIVE To conduct a literature review of one case of follicular lymphoma complicated with iliac bone Cryptococcus neoformans infection so as to raise the understanding of such pathogen in the field of HIV-negative Hodgkin's/non-Hodgkin's lymphoma.METHODS The clinical data were collected from one case of follicular lymphoma patient complicated with C.neoformans infection who was treated in Xinrui Hospital of Xin-wu District,Wuxi City on Feb.24,2023 and retrospectively analyzed.All of relevant literatures regarding to the subject were retrieved in Pubmed,CNKI,Wanfang and VIP databases,and the clinical data of the patients with HIV-negative Hodgkin's/non-Hodgkin's lymphoma with C.neoformans infection were screened out and summa-rized.RESULTS The case was a 28-year-old male and had the underlying disease of follicular lymphoma.The C.neoformans was detected by iliac bone histopathology and metagenome next generation sequencing(mNGS).The condition of the patient improved after the treatment with amphotericin B cholesterol sulphate com-pound and fluconazole.A total of 28 patients,with this case included,were involved in the literature review,23 of whom were male,and 5 were female,and the age ranged between 16 and 79 years old.With respect to major in-fection sites,there were 15(53.57％)cases of cerebral infection,9(32.14％)cases of blood infections,7(25.00％)cases of pulmonary infection,4(14.285％)cases of skin infections,2(7.14％)cases of muscle tis-sue infections,2(7.14％)cases of pleural effusion infections,2(7.14％)cases of bone infections and 1(3.57％)case of bone marrow infection.Totally 11 patients had disseminated Cryptococcus infection,accounting for 39.28％.CONCLUSIONS The C.neoformans infection is seldom detected in the patients with HIV-negative Hodgkin's/non-Hodgkin's lymphoma.The brain is the major infection site with the high probability of dissemina-ted infection.It is necessary for the hospital to deepen the understanding of the pathogen in the field of HIV-negative Hodgkin's/non-Hodgkin's lymphoma.

Epigenomic imbalance drives abnormal transcriptional processes,promoting the onset and progression of cancer.Although defective gene regulation generally affects carcinogenesis and tumor suppression networks,tumor immunogenicity and immune cells involved in antitumor responses may also be affected by epigenomic changes,which may have significant implications for the development and application of epigenetic therapy,cancer immunotherapy,and their combinations.Herein,we focus on the impact of epigenetic regulation on tumor immune cell function and the role of key abnormal epigenetic processes,DNA methylation,histone post-translational modification,and chromatin structure in tumor immunogenicity,and introduce these epigenetic research methods.We emphasize the value of small-molecule inhibitors of epigenetic modulators in enhancing antitumor immune responses and discuss the challenges of developing treatment plans that combine epigenetic therapy and immuno-therapy through the complex interaction between cancer epigenetics and cancer immunology.

Objective: To determine the heterogeneity for caries prevention service preferences among children in Anhui Province, so as to provide reference for the promotion and popularization of caries prevention services for school age children. Methods: Based on a discrete selection experiment, a face to face questionnaire survey was administered using a multi stage sampling method among 785 parents with children 3-12 years of age who were hospitalized in the stomatology clinics of 7 prefectures and cities in Anhui Province from October 2021 to October 2022. A mixed Logit model was used to evaluate caries prevention service preferences for children. Results: Four discrete choice experiment attributes included in the study were statistically significant for choice preference ( P <0.05). Compared with the control group, parents with a high school education or above preferred caries prevention services with 70%-<80% preventive effectiveness, 2-<5 and <2 km from the service point, and a high service cost ( β =0.38, 1.66, 1.64, 0.00); female parents preferred preventive services with 70%-<80% preventive effectiveness and a high service cost ( β =0.35, 0.01 ); parents of children <7 years of age preferred services with 70%-<80% preventive effectiveness ( β =0.75); parents of children with oral health preferred preventive services during winter and summer vacations ( β =-0.28); parents of children with caries preferred preventive services with a high cost per denticle ( β =0.00)( P <0.05). Conclusions Parents with different education levels, gender, child age, and oral health status have heterogeneity in dental caries prevention service preferences. The provision of targeted and precise services can improve the participation and coverage of caries prevention services for school age children.

Scoliosis is characterized by one or several segments of the spine bending sideways, accompanied by vertebral rotation and sagittal imbalance with complex etiology. Scoliosis can be caused by congenital vertebral abnormalities, asymmetry of the paraspinal muscles due to neurological lesions, and malnutrition or metabolic disorders of bone tissue. Growth hormone is a peptide hormone that plays a key role in promoting human growth and development, especially in bone growth. When the secretion of growth hormone in children or adolescents in the rapid growth stage is insufficient, it may lead to the occurrence of idiopathic short stature (ISS) and growth hormone deficiency (GHD). In clinic, ISS and GHD are mainly treated by recombinant human growth hormone (rhGH). According to some early clinical reports, in the process of rhGH treatment, many patients occur scoliosis or the original scoliosis progression is aggravated. Therefore, many scholars conclude that rhGH treatment of ISS or GHD will lead to the occurrence or development of scoliosis. However, with the increase of clinical statistics and the further progress of research, many scholars found that rhGH treatment of ISS or GHD will only increase the Cobb angle of patients with scoliosis, but will not lead to the occurrence of scoliosis, that is, rhGH treatment of ISS or GHD will not increase the prevalence of scoliosis. At present, whether rhGH treatment of ISS and GHD can lead to scoliosis and aggravation of scoliosis remains controversial. Therefore, this paper summarizes and analyzes the correlation research on the risk of scoliosis complications in children treated with rhGH, and concludes that age, gender, body mass index, and growth potential are risk factors for the development or progression of scoliosis during treatment, and discusses the balance of advantages and disadvantages of using rhGH for ISS or GHD to provide a direction for future clinical guidance.

Objective To analyze the epidemiological characteristics of hepatitis B in Guangzhou from 2006 to 2018. Methods The data were retrieved from the National Infectious Disease Surveillance Information Report Management System. Descriptive methods were used to analyze and summarize the results. Chi-square test was used for statistical analysis of classification data, and Joinpoint software was used to analyze the annual change percentage and trend. Results A total of 292 674 cases of hepatitis B were reported in Guangzhou from 2006 to 2018, and the annual average reported incidence was 182.2 per 100,000. Chronic hepatitis B was the main type, accounting for 89.9%. The incidence rate of males (241.6 / 105) was higher than that of females (117.9 / 105), with a ratio of 2.0:1. During the period from 2006-2018, the reported incidence of hepatitis B in Guangzhou first increased, reached the highest in 2008, and then decreased year by year. There was no significant difference in the number of HBV cases among different months. The average onset age of hepatitis B reported in Guangzhou was 39.3 years old, and the average onset age increased year by year from 2006 to 2018. Conclusion The incidence rate of hepatitis B in Guangzhou has decreased since 2008, but it was still higher than the national average incidence rate. The hepatitis B infection in Guangzhou remains a big issue. It is suggested to further strengthen the prevention and control of hepatitis B in adults by maintaining a national immunization program for children, thereby reducing the epidemiological level of hepatitis B in Guangzhou.
