It could support the query and discovery of nodes（syndrome elements， syndrome types and treatment methods）， as well as the relationship between each node. ConclusionBased on the literature data， this study constructed a knowledge map for TCM treatment of DPN， which brought together various methods of TCM treatment of DPN， including internal and external treatment. The whole chain knowledge structure of syndrome differentiation and classification for DPN treatment is formed from syndrome element analysis， syndrome type composition to treatment method selection， which can provide new ideas and methods for literature data to serve clinical and scientific research work， as well as reference for visualization of TCM literature knowledge， intellectualization of TCM knowledge services and the standardization of TCM diagnosis and treatment.

Analysis of pretreatment drug resistance and polymorphic sites in CRF08_BC strains among HIV-1 patients / 中华微生物学和免疫学杂志

Objective:To investigate the prevalence of pretreatment drug resistance and the genetic polymorphism of CRF08_BC strains among HIV-1 patients in China.Methods:This cross-sectional survey involved the plasma samples of HIV patients in a national pretreatment HIV drug resistance survey conducted in 2018. RNA was extracted from the samples. The fragments containing protease and partial reverse transcriptase (PR/RT) regions were obtained and sequenced. Drug resistance was analyzed using Stanford HIVdb Program. Differences in polymorphic mutations between drug-resistant and non-drug-resistant HIV-1 strains were analyzed by Chi-square test or Fisher′s exact test. The association between drug-resistant and polymorphic mutations was evaluated using CorMut R package. Molecular transmission networks were constructed using HIV-TRACE software. Results:Totally 465 partial pol sequences were obtained from individuals with CRF08_BC infection in 25 provinces and cities. The total pretreatment drug resistance rate was 17.8% (83/465). The pretreatment drug resistance rates to non-nucleoside reverse transcriptase inhibitors (NNRTIs), nucleoside reverse transcriptase inhibitors (NRTIs) and protease inhibitors (PIs) were 16.6% (77/465), 1.1% (5/465) and 0.9% (4/465), respectively. The resistance rate to rilpivirine (RPV) was the highest (15.7%, 73/465). The most common mutation was E138A (11.6%, 54/465). There were six polymorphic mutations (S162C, K102Q, T200A, V179E, I202V, T200M) that co-variated with E138A. The molecular transmission network showed that patients infected with CRF08_BC strains carrying the resistant mutations at position E138 mainly gathered in clusters in Yunnan and Sichuan, and the highest degree of connection was in Lincang, Yunnan. Conclusions:In China, HIV-1 CRF08_BC-infected patients showed a high rate of pretreatment resistance to one of the second-generation NNRTIs, namely RPV. Further researches were warranted to evaluate the impacts of co-mutations of the E138A mutation and polymorphic sites on HIV resistance and replicative capacity.

Clinical Evidence of Oral Chinese Patent Medicines in Treatment of Chronic Kidney Disease： A Scoping Review / 中国实验方剂学杂志

ObjectiveTo review the information and clinical studies of oral Chinese patent medicines （CPMs） for chronic kidney disease （CKD）. MethodThe CPMs for treating CKD were retrieved from the Pharmacopoeia of the People's Republic of China， National Essential Drugs List， and Medicine List for National Basic Medical Insurance， Employment Injury Insurance and Maternity Insurance. China National Knowledge Infrastructure（CNKI）， VIP， Wanfang Data， SinoMed， PubMed， Embase， Cochrane， and Web of Science were searched for the clinical trials of the treatment of CKD by CPMs from their inception dates to September 25， 2022. A database was established with the collected CPMs， and then the general conditions of the clinical trials were analyzed and presented visually. ResultA total of 16 CPMs for CKD were included in this study， including 5 classical traditional Chinese medicine （TCM） prescriptions involving Rehmanniae Radix and 11 new CPMs. The indications of the TCM prescriptions did not mention the corresponding western disease names， and those of the new CPMs mainly included chronic renal insufficiency， chronic renal failure， and chronic nephritis. Four CPMs were prepared with single Chinese medicine or active components. Specifically， Bailing Preparation and Jinshuibao Preparation were mainly prepared with the powder of Cordyceps， and the main components of Haikun Shenxi capsules and Huangkui capsules were fucoidan sulfate and the flower extract of Abelmoschi Corolla， respectively. The CPMs mainly exerted tonifying and eliminating effects on the lung， spleen， and kidney. A total of 892 clinical trials were screened out， covering all the areas in China and presented an increasing trend. Bailing Preparation was the most studied， followed by Niaoduqing Preparation. Among the 892 studies， 475 focused on single CPMs without combination with other CPMs or therapies. These studies mainly compared between conventional intervention and conventional intervention + CPM， which accounted for 75.58%. The 475 studies covered different kidney diseases， such as chronic kidney disease， chronic renal failure， nephrotic syndrome， diabetic kidney disease， IgA nephropathy， and membranous nephropathy， and involved a variety of populations including the elderly and children. Thirty-six studies evaluated TCM syndromes， reflecting the characteristics and advantages of TCM treatment. ConclusionThere are abundant oral CPMs for CKD， with varied efficacy and characteristics for different kidney diseases. However， the instruction manuals of the oral CPMs are not detailed or standard. According to the clinical research evidence in this field， the research on oral CPMs for CKD is characterized by a wide scope， rich study types， and wide disease coverage， while the sample size and quality remain to be improved.

Introduction to Health Research Priority Setting Methods and Application Recommendations of Methods in Field of Traditional Chinese Medicine / 中国实验方剂学杂志

Health research priority setting， based on the existing disease burden or healthcare needs， screens out specific areas or topics with relatively high research priority by scientific and systematic methods， and optimizes the allocation of health resources by influencing healthcare decision-making， so as to alleviate the imbalance between regional or global health and development. Many developed countries have carried out related research and practical work on different scales， and the World Health Organization （WHO） attaches great importance to the transformation and application of relevant achievements in developing countries. As the largest developing country in the world， China's research in this field started relatively late， and only a small number of scholars have carried out part of the localization methodology research and practice according to the specific national conditions. However， health research priority setting has not yet attracted the attention of large-scale research institutions or government organizations in China. Although the priority setting is rarely mentioned in the research on traditional Chinese medicine （TCM）， the research and decision-making on the diseases responding specifically to TCM can also be regarded as the practical work of exploring the priority of TCM. Policymakers have a sense of priority support in the "priority of TCM research"， but the decisions from the top design are mainly based on the consensus reached by high-level think tanks. There is a lack of extensive research， and moreover， the data of multiple stakeholders are not included. Therefore， it is urgent to introduce appropriate priority setting methods to solve the problem of transparency and scientificity in the decision-making process. Given the perspective of the specific implementation， the present study introduced three international priority setting methods， i.e.， the James Lind Alliance and Priority Setting Partnerships（JLAPSP，）the Child Health and Nutrition Research Initiative（CHNRI）， and the Council on Health Research and Development （COHRED）， and presented relevant recommendations on how to apply them in the research of TCM， which is expected to provide references for the local research.

Clinical Evidence of Chinese Patent Medicines in Treatment of Respiratory Diseases in Children： A Scoping Review / 中国实验方剂学杂志

ObjectiveThis study performed a scoping review to comprehensively analyze and report the information on the instructions of Chinese patent medicines and clinical research evidence for the treatment of respiratory diseases in children. MethodChinese patent medicines against respiratory diseases in children were obtained by searching the three major drug catalogues. The Chinese and English databases were searched for relevant literature，followed by data statistics and visualized analysis. ResultAfter screening and analysis，52 Chinese patent medicines were included，involving nine dosage forms. The main drugs were Scutellariae Radix，Armeniacae Semen Amarum，Forsythiae Fructus，etc. The main functions included clearing heat and releasing exterior syndrome，and relieving cough and dissipating phlegm. The indications mainly included common cold with wind-heat syndrome and cough in children. Adverse drug reactions and contraindications were only specified in 19.23% （10/52） of Chinese patent medicines，and the rest only displayed "unclear". A total of 279 articles were included，including 277 articles from Chinese Core Periodicals and two articles from SCIE. In terms of research type，those articles included 253 randomized controlled trials （RCTs，with six dosage form/dose comparisons involved），11 retrospective analyses based on Hospital Information System （HIS） data，one case series，13 systematic reviews/Meta-analyses （with two network Meta-analyses involved），and one economic evaluation article. Among them，72.76% （203/279） of the articles were published in the Core Journals of Chinese Science and Technology. Only 33 Chinese patent medicines were involved，and Xiaoer Feire Kechuan Oral Liquid was the top 1 under investigation，accounting for 15.71% （44/280）. The indicated diseases were mainly infantile pneumonia，bronchitis，respiratory tract infection，cough，asthma，and other western medicine diseases. Xiaoer Chiqiao Qingre Granules and Xiaoer Dingchuan Oral Liquid were used off-label. The sample size was concentrated in 51-150 cases，accounting for 67.17% （178/265）. The interventions in the experimental group were mainly Chinese patent medicine + western medicine + basic treatment or Chinese patent medicine + western medicine. The main outcomes were the effective rate and the improvement of clinical symptoms. The adverse reactions were mainly gastrointestinal reactions，drug-induced skin symptoms，etc.，and two studies have shown that drug doses were associated with adverse reactions. ConclusionIn research years，the research on Chinese patent medicines in the treatment of respiratory diseases in children has advanced rapidly. However，there are still some problems that need to be resolved in the future，such as incomplete information on drug content in the instruction，concentrated drugs to be studied，limited indications，failure to highlight the characteristics of traditional Chinese medicine （TCM） syndromes，unstandardized research design，and an incomplete reflection of Chinese patent medicine.

Causal relationship among quality factors, emotional responses, and satisfaction of school food service in Henan province, China

BACKGROUND/OBJECTIVES@#School food service has played an important role in promoting the health and physical condition of students by providing students with a balanced and nutritious diet. Therefore, boosting the quality of school food service and improving the students’ satisfaction is critical. For this purpose, this study examined the structural causal relationship among the quality of school food service factors, emotional responses, and satisfaction in China. @*SUBJECTS/METHODS@#This study was conducted with 4th–6th-grade students from 6 junior high schools in Henan province of China, with 590 questionnaire responses (87.3%) collected and statistically analyzed. @*RESULTS@#The school food service quality factors (including menu management, dietary education, facilities management, price and food distribution management, and personal hygiene during meals) must be enhanced to boost the students’ satisfaction. In addition, the study used questionnaire survey data to validate the full mediation of students’ emotional responses between school food service quality factors and student satisfaction. @*CONCLUSIONS@#Students’ emotions also play an important role in influencing the quality of school food service, all of which affect the emotional responses of students. Therefore, students’ positive emotions are an important indicator for improving the quality of school food service. A national support policy is necessary for the ongoing maintenance and development of various programs that drive students' satisfaction and promote the adoption of education guidelines for school food service in China.

Clinical Evidence on Treatment of Otorhinolaryngologic Diseases with Oral Chinese Patent Medicine： A Scoping Review / 中国实验方剂学杂志

This paper aims to systematically retrieve and summarize the clinical evidence on oral Chinese patent medicine in otorhinolaryngology by scoping review and analyze the distribution of the evidence， which is expected to serve as a reference for clinical practice and healthcare decision-making. Seven databases were searched （from inception to March 2022） for the clinical evidence of oral Chinese patent medicine in the prevention and treatment of otorhinolaryngologic diseases， and the distribution of the evidence was discussed. A total of 248 papers from core journals/SCI were included： 238 clinical studies （185 randomized controlled trials， 46 semi-/non-randomized controlled trials， 7 case series studies）， 5 systematic reviews， 4 guidelines/expert consensuses， and 1 pharmacoeconomic study. The papers covered 26 oral Chinese patent medicines and 40 otorhinolaryngological diseases （5 ear diseases， 22 nose diseases， and 13 throat diseases）. The majority of the clinical studies included 100-300 cases. The combination of Chinese patent medicine and western medicine is the common intervention in the experimental group. The outcomes were mainly “cure rate” and improvement of clinical symptoms. Common adverse events were nausea， vomiting， rash， headache， gastrointestinal discomfort， fatigue， etc. In summary， there is a lack of high-quality clinical evidence on oral Chinese patent medicine in otorhinolaryngology. In addition， the available studies have such problems as seldom use of recognized outcomes， low quality of clinical studies， and lack of pharmacoeconomic study. In future， efforts should be made to carry out more rigorous primary and secondary research and enhance the pharmacoeconomic evaluation， in a bid to explore the advantages of Chinese patent medicine in the treatment of otorhinolaryngologic diseases and promote the more rational allocation and application of health resources.

Four Oral Chinese Patent Medicines for Treatment of Functional Dyspepsia： A Rapid Health Technology Assessment / 中国实验方剂学杂志

ObjectiveTo evaluate the safety， efficacy， and economy of the four Chinese patent medicines （CPMs）， including Simotang oral liquid， Liuwei Anxiao capsule， Baohe pill， and Jianwei Xiaoshi oral liquid in the treatment of functional dyspepsia （FD） by a rapid health technology assessment （RHTA）， thus providing evidence support for clinical decision making. MethodChina National Knowledge Infrastructure （CNKI）， WanFang Database， VIP Chinese Technology Periodical Database （VIP）， China Biology Medicine disc （CBMdisc）， PubMed， EMBASE， Cochrane Library， and Web of Science were searched by computer from inception to March 2022. After literature screening， data extraction， and quality evaluation， the descriptive analysis of the results combined with visual charts was performed. Nineteen studies were included， involving 18 randomized controlled trials （RCTs） and 1 Meta-analysis. Neither economic studies nor health technology assessment （HTA） reports were retrieved. ResultThe four CPMs were safe and effective in the treatment of FD， but economic research was lacking. Among them， Simotang oral liquid could be used for children with FD and FD caused by qi and food stagnation， liver and spleen disharmony， and liver and spleen stagnation. Liuwei Anxiao capsule could be used for adult patients with FD caused by food stagnation. Baohe pill could be used for the elderly with FD. Jianwei Xiaoshi oral liquid could be used for children with FD caused by spleen and stomach weakness. ConclusionThe four CPMs have their advantages in the treatment of FD. Among them， the clinical universality of Simotang oral liquid is higher. However， the quality of clinical evidence is generally low， and comparative analysis among drug dosage forms is lacking. In the future， it is necessary to improve， apply， and promote RHTA for rapid evidence production while carrying out a more standardized and scientific evidence-based demonstration of the comprehensive clinical efficacy of CPMs.

Clinical Evidence of Treatment of Constipation with Oral Chinese Patent Medicine： A Scoping Review / 中国实验方剂学杂志

This study systematically and comprehensively sorted out the application status of Chinese patent medicines for the treatment of constipation in the clinic， to provide scientific evidence for future research directions and clinical drug use in this field. Based on the method of scoping review， the Chinese patent medicines for the treatment of constipation were retrieved from three drug lists to obtain the medicines that needed to be evaluated. A comprehensive and systematic search was carried out on the included studies on the treatment of constipation by Chinese patent medicines through eight Chinese and English databases， and the included studies were integrated and analyzed. The results were displayed in combination with charts. Thirty-four Chinese patent medicines and 118 studies were included in this study. According to the efficacies， Chinese patent medicines were divided into 4 categories， namely eliminating accumulation， purging fire， promoting Qi， and moistening bowels， involving 125 Chinese medicines. The overall attention of constipation research is on the rise. Marenwan （granules or soft capsules） gained the highest attention， with 42 studies， followed by Qirong Runchang oral liquid， with 21 studies， and Biantong tablets （capsules）， with 19 studies. There are 10 studies on Congrong Tongbian oral liquid. Seventeen Chinese patent medicines had no corresponding clinical research. There were 8 study design types， and all drugs were mainly randomized controlled trials except Danggui Longhui pill. Among the intervention types， the comparison between Chinese patent medicines and western medicines was the most. The highest outcome indicators were efficacy， safety evaluation， and main symptoms or scores， and there was a lack of a unified core outcome indicator set. There were few studies on adverse reactions and the economy. Only 11.86% of the studies were funded. Clinically， Chinese patent medicines are widely used in the treatment of constipation， and the amount of related research shows an increasing trend. However， some Chinese patent medicines lack corresponding clinical evidence， and the published research has problems such as unrigorous design， ununified criteria for efficacy evaluation， lack of comprehensive evidence studies， and insufficient funds. It is hoped that more investment will be made in this field in the future， and more attention will be paid to drugs with relatively blank research and constipation syndromes with few treatments. Comprehensive evidence studies such as systematic reviews should be carried out actively. And the study design should be standardized to provide reliable evidence for the treatment of constipation with Chinese patent medicines.

Changes of pancreatic gene expression and signal transduction pathway in large conductance calcium-activated potassium channels gene knockout rats detected by transcriptome sequencing / 中华胰腺病杂志

Objective:To investigate the differences of gene expression and signal transduction pathways in large conductance calcium-activated potassium channels(BKCa) gene knockout rats and analyze the role of BKCa gene in pancreas.Methods:Three adult female BKCa knockout SD rats (BKCa knockout group) were donated by Professor Wang Wei from Department of Pathology and Physiology of Basic Medical College of Capital Medical University, and three wild type adult femal SD rats were used as wide-type group. The whole pancreas was resected and RNA was extracted. RNA transcriptome sequencing (RNA-seq) technology was used for sequencing and DESeq2 differentiation analysis software was used for screening differentially expressed genes between two groups, and the gene ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment analysis were performed. The key genes were validated by RT-PCR.Results:18 258 genes were detected by sequencing in the 2 groups. There were statistically significant differences in the expression of 348 genes screened by DESeq2, 200 of which were highly expressed in the pancreas of BKCa knockout group, and 148 of which were low-expressed. 214 differentially expressed genes enrichments were found in GO database, including 25 involved in biological process, 18 in cell components and 14 molecular functions. All 348 differentially expressed genes were found in KEGG database, 15 of which were significantly enriched in PI3K/Akt signaling pathways. RT-PCR results showed that the expression of key genes Hsp90ab1, Hsp90aa1, Foxo3a and Col1a2 in the BKCa knockout group was significantly higher than that in wide type group ( P<0.0001), while Thbs1, Pik3r1 and Ppp genes were not significantly different. Conclusions:Differentially expressed genes and related important regulatory signaling pathways were screened out between BKCa knockout SD rats and wild-type SD rats at the transcriptional level, and PI3K/Akt pathway was found to be the most enriched, providing an important clue for predicting the function of BKCa in the pancreas.

AIM:To study the effects of N-palmitoylethanolamide ( PEA) on the anxiety-and depression-like behaviors of the mouse model induced by restraint stress , and to explore the possible mechanism of anxiolytic and antide-pressant effects of PEA .METHODS:The mice were intragastrically treated with 2.5, 5 and 10 mg/kg of PEA for 21 con-secutive days once daily .Thirty min after intragastric administration , the mice ( except the normal control group ) were placed in the glass tube to accept 4-h chronic restraint stress for 21 d.After the last administration , the mice were submit-ted to the forced stress test and the open field test (OFT) to observe the effects of PEA on the depression-like behaviors. The cumulative immobility time was recorded during the 4-min interval in the forced swimming test ( FST) or during the 5-min interval in the tail suspension test (TST).The elevated plus maze (EPM) test was used to investigate the effect of PEA on the mouse anxiety-like behaviors , and the water maze method was used to investigate the learning and memory abi-lities, spatial orientation and cognitive function of mice .After the behavior tests , the serum was collected and the hippo-campus was removed . The serum contents of adrenocorticotropic hormone ( ACTH ) , cortisol ( CORT ) and 5-hydroxytryptamine (5-HT) in the hippocampus were detected by ELISA .The changes of acetylcholinesterase ( AChE) ac-tivity in the hippocampal homogenate was measured by spectrophotometry .RESULTS:Compared with model group , in the FST or TST, the immobility time in the mice treated with PEA at 2.5~10 mg/kg and fluoxetine was significantly reduced . In the OFT, the total locomotion distance and total movement time were increased significantly in the mice , but only 10 mg/kg PEA and fluoxetine increased the numbers of rearing .In the EPM test , the percentage of the time spent in open arms, the entries into open arms and the total locomotion distance in 4 arms in the mice were significantly increased .In wa-ter maze test , PEA at 5 and 10 mg/kg and fluoxetine significantly shortened the latency to find the security zone in the mice, and PEA at 10 mg/kg and fluoxetine obviously shorten the swimming distance .Compared with model group , PEA at 10 mg/kg and fluoxetine reduced the mouse serum levels of ACTH and CORT , and the adrenal index , increased the 5-HT content and decreased the AChE activity in the hippocampus .CONCLUSION:PEA produces antagonistic effects on an-xiety-and depression-like behaviors in the mice induced by restraint stress .Its specific mechanism may be related to the re-gulation of the hypothalamic-pituitary-adrenal axis function by increasing the 5-HT level in hippocampus , thus participating in the regulation of central cholinergic system .

Clinical Observation of Catgut-embedding Therapy Based on Respiration-induced Reinforcing and Reducing for Treatment of Simple Obesity with Spleen Deficiency and Dampness Retention / 广州中医药大学学报

Objective To observe the therapeutic effect of catgut-embedding (CE) therapy based on respiration-induced reinforcing and reducing and electro-acupuncture (EA) therapy in treating simple obesity with spleen deficiency and dampness retention. Methods Sixty simlpe obesity patients with spleen deficiency and dampness retention were randomized into CE group and EA group, 30 cases in each group. The acupoints selected for the two groups were the same, and the points were Zhongwan, Shuifen, Qihai, Guanyuan, Tianshu, Liangmen, Daheng, Fujie, Quchi, Xuehai, Yinlingquan, Fenglong, and Ashi. CE group was given CE therapy with the needling for CE therapy referred to the respiration-induced reinforcing and reducing method, and EA group was given EA therapy for 2 continuous treatment courses, 4 weeks constituting one course. Body mass and body mass index (BMI) of the two groups before and after treatment were observed, and the clinical efficacy was also evaluated after treatment. Results (1) After treatment for 2 courses, body mass and BMI of the two groups were obviously decreased(P 0.05). (2) The total effective rate of CE group was 90.0% and that of EA group was 86.7%, and the difference between the two groups was insignificant (P > 0.05). Conclusion The therapeutic effect of CE therapy based on respiration-induced reinforcing and reducing in treating simple obesity with spleen deficiency and dampness retention is similar to that of EA therapy, and the patients can choose anyone of them for loosing body weight according to the preference.

Combined ozone hydrotherapy for atopic dermatitis:evaluation of efficacy and detection of interleukin-4 and nerve growth factor levels in peripheral blood from patients before and after treatment / 中华皮肤科杂志

Objective To evaluate the clinical efficacy and safety of combined ozone hydrotherapy for the treatment of atopic dermatitis(AD). Methods A total of 60 patients with moderate or severe AD aged from 6 to 65 years were enrolled, and randomly and equally divided into a test group and a control group. Both the two groups were treated with oral levocetirizine capsules 5 mg once a day, topical tacrolimus ointment twice a day, and topical moisturizers. The test group was additionally treated with ozone hydrotherapy 3- 5 times every week. The treatment lasted 2 weeks. The severity scoring of atopic dermatitis (SCORAD) score, visual analog scale (VAS) score, dermatology life quality index (DLQI) or children′s dermatology life quality index (CDLQI) score were assessed before and after the treatment, and compared between the two groups. Enzyme?linked immunosorbent assay(ELISA) was performed to measure the levels of interleukin?4(IL?4)and nerve growth factor(NGF)in peripheral blood from the patients before and after the treatment. Results After 2?week treatment, the SCORAD scores, VAS scores and DLQI/CDLQI scores significantly decreased from 42.13 ± 16.03, 7.14 ± 2.12 and 14.92 ± 5.94 before the treatment to 27.3 ± 11.01, 2.23 ± 1.31 and 9.69 ± 4.17 respectively in the test group(all P0.05). Conclusion Combined ozone hydrotherapy can effectively and safely improve the condition of patients with AD, likely by decreasing the levels of IL?4 in peripheral blood.
