Acupuncture-moxibustion therapy has been known to ameliorate the symptoms of functional gastrointestinal disorders (FGIDs), although its mechanism remains unclear. The paper reviews the articles on acupuncture-moxibustion therapy for FGIDs in recent 5 years, and it is revealed that acupuncture-moxibustion therapy can alleviate FGIDs symptoms through regulating gastrointestinal motility, modulating visceral hypersensitivity, improving the impaired gastric-duodenal mucosal barrier and inflammation, balancing intestinal microbiota, and adjusting the gut-brain axis. Currently, the molecular mechanism of acupuncture-moxibustion therapy remains unknown for FGIDs, the specific disease target is not identified, and the interaction among various molecules is not elucidated adequately. The researches in the future should employ advanced technologies and methodologies to comprehensively and deeply explore and clarify the mechanism of acupuncture- moxibustion therapy for FGIDs.

OBJECTIVE: To analyze the rules of moxibustion for low back pain by ZHOU Meisheng by using data mining and knowledge graph technology. METHODS: Taking the medical cases of moxibustion for low back pain from ZHOU Meisheng's legacy manuscripts and existing works as the research objects, information on disease types, symptoms, tongue manifestations, pulse conditions, syndrome patterns, moxibustion methods and acupoints were collected. Frequency statistics and community analysis were conducted by the ancient and modern medical record cloud platform V 2.3.7, cluster analysis of high-frequency acupoints was performed by SPSS26.0, association rule analysis of high-frequency acupoints was performed by SPSS Modeler 18.0, and the generated linked data were imported into Cytoscape 3.9.1 for complex network analysis. Knowledge graph of moxibustion for low back pain by ZHOU Meisheng was constructed based on the results of data mining. The data storage and display of knowledge graph were realized through the Neo4j 3.5.25 graph database, and the Cypher query language was used for knowledge graph retrieval and discovery. RESULTS: A total of 219 medical cases were collected, involving 14 disease types, 85 related clinical symptoms, 5 related TCM syndrome types, and 6 moxibustion methods. The acupoints were mostly attributed to the governor vessel, the bladder meridian of foot-taiyang, non-meridian and non-acupoint areas. The core prescription of acupoints derived from complex network analysis included tender points, Shenshu (BL23), Jinsuo (GV8), Yinjiao (CV7), Yaoyangguan (GV3), Yanglingquan (GB34), which were largely coincides with high-frequency acupoints. Cluster analysis obtained 4 cluster combinations. Community analysis yielded 6 communities, each corresponding to different acupoints.The constructed knowledge graph contained 187 nodes and 696 relationships, by retrieving clinical elements related to low back pain, the disease-moxibustion association graph, disease-acupoint association graph, accompanying symptom-acupoint association graph and syndrome type-matching point association graph were obtained. CONCLUSION When treating low back pain with moxibustion, ZHOU Meisheng adopts the principle of promoting circulation, distinguishing diseases to determine the treatment, selecting acupoints according to the diseases, and matching points according to the symptoms.And taking tender points, Shenshu (BL23), Jinsuo (GV8), Yinjiao (CV7), Yaoyangguan (GV3), Yanglingquan (GB34) as core acupoints, combined with tenderness point selection, acupoint selection based on meridian and zangfu syndrome differentiation, "sunshine area" acupoint selection, yin-yang acupoint matching.

Objective:To investigate Helicobactor pylori (H. pylori) infection status and interfamilial transmission pattern in Zhengzhou area. Methods:A cross-sectional study was conducted from September 2020 to march 2021, among 731 individual from 266 families randomly selected from 9 communities of Zhengzhou area. H. pylori infection status was determined by serum antibody tests, and 13C-urea breath test was performed in the previously eradicated population to clarify the current infection status. The individual and familial infection rate, infection status for couples and children and adolescent were analyzed. Results:Among 731 individuals from 266 families, 397 of them were H. pylori positive. The individual infection rate was 54.31% (397/731); among infected individuals 77.83% (307/397) were infected with type Ⅰ strain, 22.67% (90/397) were infected by type Ⅱ strain. Annual household income ( χ2=0.419, 0.410, 0.213, all P>0.05), smoking history (χ 2=0.071, P>0.05), drinking history ( χ2=0.071, P>0.05), dining place ( χ2=0.009, P>0.05), gastrointestinal symptoms ( χ2=0.047, P>0.05), family history of gastric disease ( χ2=0.069, P>0.05), and history of gastric cancer ( χ2=0.004, P>0.05) had no significant differences between H. pylori-positive and -negative groups, but the infection rate in individuals with higher education level was lower ( χ2=4.449, P<0.05). The infection rate was significantly higher in≥18 age groups compared with<18 age groups ( χ2=6.531, 23.362, 20.671, 24.244, 37.948, 14.597 and 5.170, all P<0.05). The familial H. pylori infection rate was 87.59% (233/266), and in 61 families all member were infected (26.18%, 61/233). The positive rate was 23.08% (6/26) in 50 families with children under 18 years when both parents were infected. Among 231 coupled families, both couples were infected in 78 families (33.76%), one couple was infected in 113 families (48.92%), and both couples were not infected in 40 (17.32%). With the increase of marriage time, the infection rate of both spouses increased significantly ( χ2=7.775, 12.662, 15.487, all P<0.05). Conclusions:The distribution of H. pylori infection presents a family cluster pattern, and intrafamilial infection is an important transmission rout of H. pylori. The type I strain of H. pylori is the dominate strain in this area.

OBJECTIVE: To investigate the effects of high-altitude hypoxic environment on the expression of pregnane X receptor (PXR) in rat liver and related mechanism. METHODS: Wistar rats were randomly divided into five groups with 8 rats in each group, the rats were exposed to high-plateau hypoxia for 0 (control group), 12, 24, 36 and 48 h, respectively. Abdominal aortic blood samples were collected for blood gas analysis. HE staining was used to observe the pathological changes of liver tissue. The expression levels of PXR mRNA in liver tissues were determined by RT-PCR. Western blot analysis was performed to determine the protein expression of PXR and protease SUG1 in liver tissues of rats. RESULTS Compared with the control group, the blood pH of the rats decreased after 12 h of acute hypoxia. After 24 h exposed to hypoxia, SaO₂ was lower than 80%, PaO₂ was lower than 60 mmHg (1 mmHg=0.133 kPa); and PaCO₂ increased after 48 h exposed to hypoxia (P<0.05). There was obvious edema in the central vein of the liver tissue at 12 h and 24 h after exposure to hypoxia. The liver tissue of the rats exposed to hypoxia for 36 h and 48 h showed inflammatory infiltration. The expression of PXR mRNA was significantly decreased by 63%, 96%, 86%, and 85%at 12, 24, 36 h, and 48 h after exposure to hypoxia (all P<0.05), respectively. The protein expression of PXR was significantly up-regulated by 93%and 99%after 36 h and 48 h exposure to hypoxia (all P<0.05), respectively. The protein expression of proteinase SUG1 decreased by 14%, 34%and 46%after 24, 36 and 48 h after hypoxia (all P<0.01). CONCLUSIONS Acute hypoxia at high altitude can affect the expression of nuclear receptor PXR in rat liver, and protease SUG1 may be a regulatory factor for PXR expression in hypoxia.

Objective Lipid metabolism disorder can lead to male sterility, but its mechanism of affecting spermatogenesis and testis microenvironment remains unclear.This study aimed to investigate the effects of high fat diet on reproductive function and the expression of Ox-LDL within testis in male mice. Methods 16 C57BL/6 mice aged 8 weeks were divided into two groups by random number table method.High fat diet group was fed with high fat diet while normal fat diet group was fed with normal fat diet .At the end of 16 weeks, the levels of TG, TC, Ox-LDL and testosterone in serum were measured.The sperm concentration and motility from caudal epi-didymis were analyzed.The testis structure was observed by HE stai-ning.The localization and expression of Ox-LDL in testis were detec-ted by immunohistochemical technique. Results Compared with the normal diet group mice, the body weight (P<0.05) and the ser-um levels of TC [(2.31 ±0.33)mmol/L vs (6.54 ±0.31)mmol/L, P<0.01], Ox-LDL [(0.32 ±0.03)mg/L vs ( 0.44 ±0.06)mg/L, P<0.01] increased in high fat diet group mice significantly.The serum level of TG was of no significant difference(P>0.05).The serum level of testosterone[(3.64 ±0.43)mg/L vs (0.40 ±0.14) mg/L, P<0.01], the sperm concentration[(9.95 ±0.75)106/mL vs (5.66 ±1.51)106/mL, P<0.01] and the sperm motility[(54.69 ±17.84)%vs (32.48 ±5.80)%, P<0.01] decreased in high fat diet group significantly.HE staining also showed that the amount of Leydig cells, spermatids and spermatozoons reduced obvi-ously in high fat diet group.Immunohistochemistry staining showed that Ox-LDL was mainly distributed around Leydig cells of mice tes-tis.The expression of Ox-LDL in high fat diet group increased significantly ( P<0.01) . Conclusion The expression of Ox-LDL in Leydig cells of high fat diet C57BL/6J mice increases significantly, which may inhibit testosterone biosynthesis and affect spermatogen-ic function.
