To summarize Professor WANG Jianmin's experience in cathartic colon from "keeping sweet to return liquid". It is believed that the key to the pathogenesis of cathartic colon is fluid consumption and intestinal dryness， including yin depletion of spleen earth， and lack of sources for body fluids production； discordance of water and fire in kidneys， and irregular distribution of body fluids； and closure of the lungs and liver leads to inability of the flow of fluids. The treatment is based on the principle of "keeping sweet to return liquid"， using sweet medicinals mainly， assistant with sour， bland and acrid medicinals， and self-prescribed Lipi Shengjin Decoction （理脾生津汤）， Wenshen Runchang Decoction （温肾润肠汤）， Kaifei Shunchang Decoction （开肺顺肠汤）， Rougan Tongbian Decoction （柔肝通便汤） could be used to regulate spleen yin by the sweet and bland， and establish qi and promote fluid production； the sweet and warm medicinals can replenish water and fire， transform into qi， and distribute body fluids； the acrid and sweet can open lung depression， descend qi， and flow the body fluids； the sour and sweet can emolliate liver， move qi， and transform fluids.

Objective To investigate the molecular mechanism of ferroptosis inhibition induced by Porphyromonas gingi-v alis(Pg)in esophageal squamous cell carcinoma(ESCC).Methods Pg-infected KYSE30 cells and KYSE70 cells as well as un-infected control cells were insulted with RSL3,followed by measurement of mitophagy and mitochondrial reactive oxygen spe-cies(mitoROS)using fluorescent confocal microscopy.The ferroptosis-related markers including malondialdehyde(MDA)and glutathione peroxidase 4(GPX4)were gauged after mitochondrial autophagy inhibitor Mdivi-1 treatment in KYSE30 cells and KYSE70 cells.Hypoxia inducible factor-1α(HIF-1α)was activated or inhibited,respectively,followed by evaluation of mitophagy using confocal immunofluorescenct microscopy as well as the expression levels of SLC39A14 and IREB2 mRNA and protein u-sing Western blotting and RT-PCR.Results RSL3-induced ferroptosis in KYSE30 cells and KYSE70 ESCC cells was accompa-nied by the decrease in mitophagy activity.Pg infection alone increased mitophagy activity in ESCC cells,and combined treat-ment with Pg and RSL3 reversed the inhibitory effects on mitophagy and the subsequent occurrence of ferroptosis in ESCC cells induced by RSL3.Inhibition of mitophagy by Mdivi-1 rescued the anti-ferroptosis effect exerted by Pg infection.In ESCC cells,HIF-1α inhibition downregulated the mRNA and protein expression levels of SLC39A14 and IREB2 paralleled by mitophagy suppression,whereas HIF-1α activation reversed these effects.Conclusion Pg inhibits ferroptosis via HIF-1α-mediated mitoph-agy activation in ESCC.

The treatment process of multiple fertilization failure and salvage fertilization in a male infertile patient was retrospectively analyzed. The patient underwent in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) in another hospital for 3 cycles, all of which had fertilization abnormalities. The complex heterozygous mutation of PLCZ1 gene was detected by infertility gene paneland confirmed by Sanger sequencing in the Reproductive Medicine Center of Renmin Hospital, Hubei University of Medicine, and the gene mutation was derived from both parents. No abnormal mutations were found in the woman's genetic testing. The woman underwent progestin-primed ovarian stimulation, resulting in the retrieval of 9 oocytes. ICSI combined with 10 μmol/L ionomycin assisted oocyte activation (AOA) was applied to all mature eggs,resulting in 7 normal fertilized oocytes and 7 cleavage embryos, 2 high-quality cleavage embryos were frozen. Two months later, the woman underwent frozen-thawed embryo transfer to obtain biochemical pregnancy. Simultaneously, we reviewed the literature on PLCZ1 gene mutations and AOA related literature at home and abroad. From this case we can draw the following conclusions: 1) When no fertilization or polyspermia occurs in an IVF cycle and total fertilization fails in ICSI, genetic testing of both spouses is required to find genetic factors. 2) The mutation of PLCZ1 gene mainly leads to fertilization failure. ICSI combined with AOA is an effective method to rescue fertilization failure. Ionomycin has a significant effect on oocyte activation, and has no effect on embryo formation. However, we still need to accumulate case data to verify the safety of ionomycin AOA.

Objective:To investigate variation and correlation of type 2 intrinsic lymphocyte(ILC2)and related factors in acute and chronic brucellosis,to identify immune role of ILC2 in chronic brucellosis.Methods:Forty-three patients with acute brucel-losis and 45 patients with chronic brucellosis were compared with 49 healthy controls.ILC2 level in each group was detected by flow cytometry.mRNA level of GATA3 in PBMC was detected by fluorescence quantitative PCR.Serum IL-33,ST2,IL-4 and IL-13 levels were detected by ELISA.ALT and AST levels were measured by fully automatic biochemical analyzer.Results:ILC2 level,GATA3 mRNA in PBMC,serum IL-33,IL-4 and IL-13 levels in chronic brucellosis group were significantly higher than healthy control group and acute brucellosis group(P<0.01).Correlation analysis showed that ILC2 level was positively correlated with GATA3 mRNA,IL-33,IL-4 and IL-13 levels,while negatively correlated with ST2 level.ROC curve suggested that ILC2,GATA3,IL-33 and ST2 had good predictive ability for severity of brucellosis patients(AUC>0.7).Conclusion:Increase of ILC2 and its related factors are closely related to chronic brucella infection,which may play an important immune role in pathogenesis of brucella infection.

BACKGROUND: The effect of the interval between previous Helicobacter pylori (H. pylori) eradication and rescue treatment on therapeutic outcomes remains unknown. The aim of this study was to investigate the association between eradication rates and treatment interval durations in H. pylori infections. METHODS: This prospective observational study was conducted from December 2021 to February 2023 at six tertiary hospitals in Shandong, China. We recruited patients who were positive for H. pylori infection and required rescue treatment. Demographic information, previous times of eradication therapy, last eradication therapy date, and history of antibiotic use data were collected. The patients were divided into four groups based on the rescue treatment interval length: Group A, ≥4 weeks and ≤3 months; Group B, >3 and ≤6 months; Group C, >6 and ≤12 months; and Group D, >12 months. The primary outcome was the eradication rate of H. pylori . Drug compliance and adverse events (AEs) were also assessed. Pearson's χ2 test or Fisher's exact test was used to compare eradication rates between groups. RESULTS: A total of 670 patients were enrolled in this study. The intention-to-treat (ITT) eradication rates were 88.3% (158/179) in Group A, 89.6% (120/134) in Group B, 89.1% (123/138) in Group C, and 87.7% (192/219) in Group D. The per-protocol (PP) eradication rates were 92.9% (156/168) in Group A, 94.5% (120/127) in Group B, 94.5% (121/128) in Group C, and 93.6% (190/203) in Group D. There was no statistically significant difference in the eradication rates between groups in either the ITT ( P = 0.949) or PP analysis ( P = 0.921). No significant differences were observed in the incidence of AEs ( P = 0.934) or drug compliance ( P = 0.849) between groups. CONCLUSION: The interval duration of rescue treatment had no significant effect on H. pylori eradication rates or the incidence of AEs. REGISTRATION ClinicalTrials.gov , NCT05173493.

OBJECTIVE To investigate the time-effect relationship of ginger-partitioned moxibustion in treating fecal inconti-nence in patients with mild to moderate active Crohn's disease so as to optimize moxibustion duration and provide a basis for clinical application.METHODS A total of 128 patients with Crohn's disease complicated by fecal incontinence who met the inclusion crite-ria were selected as the study subjects.They were divided into a control group and three experimental groups(experimental group Ⅰ,Ⅱ,and Ⅲ)of 32 patients each using a stratified random method(with 1 dropout in experimental group Ⅰ).Patients in the control group received routine anti-tumor necrosis factor-α monoclonal antibody(adalimumab)treatment,while patients in the experimental groups received ginger moxibustion therapy in addition to the treatment provided to the control group.Among them,experimental groupⅠ received treatment for 20 minutes,experimental group Ⅱ for 40 minutes,and experimental group Ⅲ for 60 minutes.The course of treatment for all four groups was 3 months.Changes in TCM syndrome scores were compared before and after treatment in the four groups to assess clinical efficacy.The cleveland clinic incontinence score(CCIS)was used to assess the severity of fecal incontinence,the Crohn's disease activity index(CDAI)was used to assess the degree of disease activity,and the inflammatory bowel disease ques-tionnaire(IBDQ)was used to evaluate the quality of life.Anal pressure index and peripheral blood CRP and ESR levels were mea-sured,and the relationship between moxibustion time and effect was analyzed.RESULTS After 3 months of treatment,the total TCM syndrome scores of all four groups improved to varying degrees(P<0.05,P<0.01).The total scores of groups Ⅰ,Ⅱ,and Ⅲ were supe-rior to those of the control group(P<0.05,P<0.01),while group Ⅱ had the lowest total TCM syndrome score.Group Ⅱ had the high-est overall clinical effective rate,significantly better than both the control and group Ⅰ(P<0.05,P<0.01).CCIS scores,IBDQ scores and total scores,and peripheral blood ESR levels were significantly reduced in all four groups(P<0.01),with group Ⅱ having the low-est score,lower than both the control and group Ⅰ(P<0.05,P<0.01).CRP levels were significantly reduced in groups Ⅱ and Ⅲ(P<0.05,P<0.01),both lower than the control group(P<0.05,P<0.01),with group Ⅱ lower than group Ⅰ(P<0.01).Intestinal symptom scores in the IBDQ of groups Ⅱ and Ⅲ were significantly higher than those in the control group and group Ⅰ(P<0.05,P<0.01).The maximum resting pressure of the anal canal,rectal defecation threshold,and maximum tolerance capacity all increased significantly in the four groups(P<0.05,P<0.01),but there were no significant differences among the groups(P>0.05).During the treatment,two cases of mild skin redness occurred in group Ⅲ,which resolved after treatment,with no serious adverse reactions.CONCLUSION Ginger moxibustion in the treatment of Crohn's disease complicated by fecal incontinence exhibits a time-effect relationship,with 40 minutes as the optimal duration.It can effectively improve symptoms,control inflammation,enhance quality of life,and has good safety.

In this article, we reviewed and reported the diagnosis and treatment of a pregnant woman with spontaneous ovarian hyperstimulation syndrome (sOHSS) after artificial cycle frozen-thawed embryo transfer. The patient had twins after artificial cycle frozen-thawed single embryo transfer. In the second trimester pregnancy, the patient had sOHSS and was firstly received ovarian cyst puncture and aspiration to reduce abdominal distension significantly, then she continued the pregnancy and delivered 2 girls successfully. The sOHSS is a rare disease, so the early diagnose and appropriate treatment should be taken to alleviate the symptoms and improve patients prognosis.

OBJECTIVES: To explore the association between GPSM2 expression level and gastric cancer progression and analyze the functional pathways and action mechanism of GPSM2. METHODS: We analyzed GPSM2 expression levels in gastric cancer tumors based on data from the GEPIA database and the clinical data of 109 patients. Public databases enrichment analysis were used to assess the impact of GPSM2 expression level on survival outcomes and the functional pathways and action mechanism of GPSM2. We further observed the effects of GPSM2 knockdown and overexpression on proliferation, migration and apoptosis of MGC803 cells using CCK-8 assay, colony formation assay, flow cytometry and immunoblotting and on the growth of MGC803 cell xenografts in nude mice. RESULTS: Bioinformatic analysis and immunohistochemical staining of the clinical specimens both revealed high GPSM2 expressions in gastric cancer (P<0.01). A high GPSM2 expression was significantly correlated with T3-4 stages, N2-3 stages, a carcinoembryonic antigen (CEA) level ≥5 μg/L, and a carbohydrate antigen (CA) 19-9 level ≥37 kU/L (P<0.05). Cox regression analysis identified high GPSM2 expression as an independent risk factor affecting 5-year survival of the patients (P<0.05). Gene ontology (GO) analysis suggested that GPSM2 was involved in cell cycle regulation. In MGC803 cells, GPSM2 overexpression significantly promoted cell proliferation and G1/S transition and xenograft growth in nude mice. KEGG pathway enrichment analysis indicated that GPSM2 executed its biological functions by regulating the p53 signaling pathway, which was confirmed by the results of immunoblotting experiments showing suppression of p53 signaling pathway activity in GPSM2-over expressing MGC803 cells. CONCLUSIONS GPSM2 is highly expressed in gastric cancer to affect patient prognosis by promoting tumor cell proliferation and G1/S transition possibly via inhibiting the p53 pathway.

OBJECTIVES: To analyze MYO1B expression in gastric cancer, its association with long-term prognosis and its role in regulating biological behaviors of gastric cancer cells. METHODS: We analyzed MYO1B expression in gastric cancer and its correlation with tumor grade, tumor stage, and patient survival using the Cancer Public Database. We also examined MYO1B expression with immunohistochemistry in gastric cancer and paired adjacent tissues from 105 patients receiving radical surgery and analyzed its correlation with cancer progression and postoperative 5-year survival of the patients. GO and KEGG enrichment analyses were used to explore the biological functions of MYO1B and the key pathways. In cultured gastric cancer cells, we examined the changes in cell proliferation, migration and invasion following MYO1B overexpression and knockdown. RESULTS: Data from the Cancer Public Database showed that MYO1B expression was significantly higher in gastric cancer tissues than in normal tissues with strong correlations with tumor grade, stage and patient prognosis (P<0.05). In the clinical tissue samples, MYO1B was significantly overexpressed in gastric cancer tissues in positive correlation with Ki67 expression (r=0.689, P<0.05) and the parameters indicative of gastric cancer progression (CEA ≥5 μg/L, CA19-9 ≥37 kU/L, G3-4, T3-4, and N2-3) (P<0.05). Kaplan-Meier analysis and multivariate Cox regression analysis suggested that high MYO1B expression was associated with decreased postoperative 5-year survival and was an independent risk factor (HR: 3.522, 95%CI: 1.783-6.985, P<0.05). MYO1B expression level was a strong predictor of postoperative survival (cut-off value: 3.11, AUC: 0.753, P<0.05). GO and KEGG analyses suggested that MYO1B may regulate cell migration and the mTOR signaling pathway. In cultured gastric cancer cells, MYO1B overexpression significantly enhanced cell proliferation, migration, and invasion and promoted the phosphorylation of Akt and mTOR. CONCLUSIONS High MYO1B expression promotes proliferation, migration and invasion of gastric cancer cells and is correlated with poor patient prognosis.

OBJECTIVES: To investigate the impact of high expression of transmembrane and coiled helix structural domain 1 (TMCO1) on prognosis of gastric cancer and the possible mechanisms. METHODS: TMCO1 expression in gastric cancer and its effect on gastric cancer progression and prognosis were analyzed using publicly available databases and clinical data of patients undergoing radical surgery in our hospital, and its possible biological functions were explored using KEGG and GO analyses. In gastric cancer HGC-27 cells, the effects of lentivirus-mediated TMCO1 overexpression and TMCO1 silencing on cell apoptosis, proliferation, invasion and migration were examined. RESULTS: TMCO1 expression was significantly elevated in gastric cancer tissues (P<0.05), and its high expression was positively correlated with cancer progression (P<0.001) and a lowered postoperative 5-year survival rate of the patients (P<0.05). Bioinformatic analyses suggested that TMCO1 may affect gastric cancer cell apoptosis via Wnt signaling. In HGC-27 cells, TMCO1 overexpression significantly promoted tumor cell proliferation, inhibited cell apoptosis, and enhanced cell migration and invasion, whereas TMCO1 silencing produced the opposite effects. Western blotting showed that β-catenin levels were significantly upregulated in TMCO1-overexpressing cells and downregulated in cells with TMCO1 silencing. CONCLUSIONS TMCO1 is overexpressed in gastric cancer tissues, and its high expression promotes gastric cancer progression and affects long-term prognosis of the patients possibly by activating the Wnt/ β-catenin signaling pathway to inhibit apoptosis of gastric cancer cells.
