Gastroesophageal reflux disease （GERD） is a prevalent chronic digestive disorder， affecting about 20% of the population. In addition to the typical symptoms of acid regurgitation and pyrosis， GERD can lead to chronic esophageal mucosal inflammation， thereby increasing the risk of esophageal carcinoma. Proton pump inhibitors （PPIs） have emerged as the primary pharmacological intervention due to their efficacy in reducing gastric acid production. However， the long-term use of PPIs is associated with various complications， including malabsorption of nutrients， heightened susceptibility to enteric infections， and an elevated risk of fractures. These concerns have driven the pursuit of safer and more efficacious therapeutic alternatives by both patients and healthcare providers. Recent studies have highlighted the role of persistent inflammation triggered by irritation of the esophageal epithelial cells in the pathogenesis of GERD. Such inflammation not only exacerbates mucosal damage but also contributes to the chronicity and complexity of the disease. Consequently， the development of novel anti-inflammatory therapeutic strategies has become a focus in contemporary research. Chinese herbal medicine prescriptions， with distinctive anti-inflammatory and antioxidant properties， offer a promising avenue for the management of GERD. These prescriptions， composed of a variety of herbal medicines， are prescribed in accordance with the traditional Chinese medicine （TCM） principle of harmonizing Qi， blood， and Yin-Yang， thereby addressing the underlying disease processes. Among the numerous Chinese herbal medicine prescriptions for GERD， ingredients such as Coptidis Rhizoma， Bupleuri Radix， Euodiae Fructus， Glycyrrhizae Radix et Rhizoma， and Atractylodis Macrocephalae Rhizoma are commonly utilized for their effects of inhibiting inflammation， modulating immune functions， and alleviating oxidative stress. Despite the potential in treating GERD， concrete evidence-based medical proof of these prescriptions remains limited. This review summarizes the anti-inflammatory mechanisms and prospects of Chinese herbal medicines in treating GERD， providing an outlook on the value of these medicines in the anti-inflammatory management of GERD.

BACKGROUND: Maturity-onset diabetes of the young (MODY) is the most common monogenic diabetes. The aim of this study was to assess the prevalence of MODY in phenotypic type 2 diabetes (T2DM) among Chinese young adults. METHODS: From April 2015 to October 2017, this cross-sectional study involved 2429 consecutive patients from 46 hospitals in China, newly diagnosed between 15 years and 45 years, with T2DM phenotype and negative for standardized glutamic acid decarboxylase antibody at the core laboratory. Sequencing using a custom monogenic diabetes gene panel was performed, and variants of 14 MODY genes were interpreted as per current guidelines. RESULTS: The survey determined 18 patients having genetic variants causing MODY (6 HNF1A , 5 GCK , 3 HNF4A , 2 INS , 1 PDX1 , and 1 PAX4 ). The prevalence of MODY was 0.74% (95% confidence interval [CI]: 0.40-1.08%). The clinical characteristics of MODY patients were not specific, 72.2% (13/18) of them were diagnosed after 35 years, 47.1% (8/17) had metabolic syndrome, and only 38.9% (7/18) had a family history of diabetes. No significant difference in manifestations except for hemoglobin A1c levels was found between MODY and non-MODY patients. CONCLUSION The prevalence of MODY in young adults with phenotypic T2DM was 0.74%, among which HNF1A -, GCK -, and HNF4A -MODY were the most common subtypes. Clinical features played a limited role in the recognition of MODY.

Methods: In vitro cultured hSFMSCs were divided into control group and IL-1β treated group(10 ng/ml IL-1β for 2 h), the activation of p38 MAPK was examined with western blot. Then, the gene expression and the secretion of IL-6 and IL-8 in control group, IL-1β treated group and p38 MAPK inhibitor pre-treated group(pretreatment with SB-203580 10 μmol/L prior to the addition of 10 ng/ml IL-1β) were examined by RT-PCR and cytometric bead array(CBA). Results: It was observed that the protein level of p-p38 MAPK, the secretion of IL-8 and IL-6 were increased in IL-1β treated group, and suppressed in p38 MAPK inhibitor pre-treated group. Conclusion: p38 MAPK pathway of SFMSCs might play a role in IL-6 and IL-8 secretion by SFMSCs in inflammatory environment.

Objective: To present the evolutionary path of Chinese Medical Ethics, analyze the development vein of periodical, explore the journal' s research focuses, and provide reference for related personnel to understand the development of the current research status in the field through visualization technology. Methods:Using biblio-metric method,taking "China National Knowledge Infrastructure" as source of data collection, we used the visual-ization software CiteSpace to draw scientific knowledge maps and analyzed literatures published from 1990 to 2014 in Chinese Medical Ethics. Results:The annualvolume of journal articles fluctuated upwards,with peaks in 1992, 2000 and 2009, and of which the most was in 2009, with 393 articles. "Medical Ethics" and "Doctor-patient Relationship" were hotwords in this field. The publications of domestic and foreign scholars promoted the interna-tional exchange and the development of Chinese medical ethics, and the most productive institutions were often col-leges or universities. Conclusion:Chinese Medical Ethics has effectively promoted the development of bioethics in China, more and more scholars are involved in the relative research of medical ethics, and the old, middle and young scientists and research teams inherit, cooperate and develop with each other. The cross-regional, inter-a-gency and interdisciplinary collaboration remains very limited, whichwill become the important factorinfluencingthe development of the field of Chinese medical ethics in the future.

Objective: To analyze related factors on the number of mesenchymal stem cells in the synovial fluid of the temporomandibular joint (TMJ) and provide an research basis for understanding of the source and biological role of mesenchymal stem cells derived from synovial fluid in TMJ. Methods: One hundred and twenty-two synovial fluid samples from 91 temporomandibular disorders (TMD) patients who visited in Department of TMJ Center, Guanghua School of Stomatology, Hospital of Stomatology, Sun Yat-sen University from March 2013 to December 2013 were collected in this study, and 6 TMJ synovial fluid samples from 6 normal volunteers who were studying in the North Campus of Sun Yat-sen University were also collected, so did their clinical information. Then the relation between the number of mesenchymal stem cells derived from synovial fluid and the health status of the joints, age of donor, disc perforation, condylar bony destruction, blood containing and visual analogue scale score of pain were investigated using Mann-Whitney U test and Spearman rank correlation test. Results: The number of mesenchymal stem cells derived from synovial fluid had no significant relation with visual analogue scale score of pain (r=0.041, P=0.672), blood containing (P=0.063), condylar bony destruction (P= 0.371). Linear correlation between the number of mesenchymal stem cells derived from synovial fluid and age of donor was very week (r=0.186, P=0.043). The number of mesenchymal stem cells up-regulated when the joint was in a disease state (P=0.001). The disc perforation group had more mesenchymal stem cells in synovial fluid than without disc perforation group (P=0.042). Conclusions The number of mesenchymal stem cells derived from synovial fluid in TMJ has no correlation with peripheral blood circulation and condylar bony destruction, while has close relation with soft tissue structure damage of the joint.

A method for simultaneous determination of PCDDs, dl-PCBs, BFRs and PBDD/Fs in flue gas from stationary source was developed. The sample was extracted by Soxhlet apparatus with toluene, and followed by purification through sulfuric acid partition and multi-layer silica gel column separation. The target compounds were then all separated by passing through the active carbon-dispersed silica gel column and reversal eluting. Gas chromatography coupled with a thermostable capillary column ( short length, thin stationary phase film) was operated at pulse injection mode. High resolution mass spectrometry set at low-electron-energy ionization was used for quantification. The high- and low-brominated compounds were determined simultaneously. The detection limits of this method were 0. 081-1. 2 pg for PCDD/Fs, 0. 10-0. 32 pg for dl-PCBs, 0. 14-12 pg for PBDEs, 0. 26-16 pg for new BFRs, 0. 44-3. 6 pg for tetra- to hepta-BDD/Fs and 8. 2-12 pg for OBDD/F. Recoveries ( RSDs) in spiked flue gas samples were 88%-115%(2. 9%-6. 1%) for PCDD/Fs, 84%-118% (3. 2%-10%) for dl-PCBs, 71%-135% (2. 1%-18%) for PBDEs, 71%-114% (2. 9%-7. 4%) for new BFRs, 83%-127% (5. 2%-10%) for tetra-to hepta-BDD/Fs and 52%-149% ( 23%-24%) for OBDD/F. All quality control data fell within the acceptable range specified in analysis standards for flue gas.

Objective To measure the costs of primary health services in the community for developing government compensation standard and prediction of budget in 201 5.Methods Literature review and panel discussions were used to build the index database.A two-round Delphi expert consultation determined the work to do and steps for community healthcare standards.60 community health centers were sampled by stratified random sampling for survey,and the work hours,workload and service volume of respective services in 2013 were measured according to the service standards of primary care.Results The community primary care consists of the categories of outpatient services,nursing care, laboratory tests and drug management,totaling 20 services and 88 working procedures.The total work hours of primary healthcare service at 60 community health centers were 2 557 187.9 hours,which is adjusted to 2 959 21 5.1 hours based on workload coefficients.Based on the income standards of employees at the community health centers investigated,and the human cost price which was recommended by the experts,the total costs of primary healthcare of the 60 centers were 245 million,248 million and 318 million respectively,and the average cost was 71.0 yuan,71.8 yuan and 92.1 yuan per visit respectively.By such standards,the government should subsidize 38.9 ~ 60.0 yuan per visit to the centers.The total expenditure of primary healthcare of all communities in Shenzhen in 201 5 was predicted to be 314 to 407 million,for which the government is expected to subsidize 1.68~2.58 billion.Conclusion The subsidies for community primary healthcare fall short as the cost per visit runs up in 2013 to 71.0 yuan per visit or more,far above the current subsidy of 32.1 yuan per person.The subsidy per visit should be made 50.0 yuan in 201 5.
