BACKGROUND:Endometrial receptivity is a key factor in embryo implantation in northwest Tibetan cashmere goats,and the expression of genes related to endometrial receptivity and their variable splicing are still unclear. OBJECTIVE:To analyze and explore genes and variable splicing events related to endometrial receptivity in northwest Tibetan cashmere goats. METHODS:On days 5 and 15 of pregnancy(representing pre receptive endometrium group and receptive endometrium group),three northwest Tibetan cashmere goats were randomly selected.Endometrial tissue was collected and stained with hematoxylin and eosin to observe tissue morphology.Immunohistochemical staining was used to detect the expression of endometrial receptive marker proteins leukemia inhibitory factor and vascular endothelial growth factor.After the total RNA was extracted and the quality test was qualified,transcriptome sequencing was performed to search differentially expressed mRNAs,lncRNAs,circRNAs,and miRNAs,perform functional prediction,and analyze alternative splicing mRNAs and lncRNAs related to endometrial receptivity. RESULTS AND CONCLUSION:(1)Compared with the pre receptive endometrium group,the expression levels of leukemia inhibitory factor and vascular endothelial growth factor proteins in the endometrial tissue of the receptive endometrium group were significantly increased.(2)The sequencing results showed that the differentially expressed genes were mostly mRNA and lncRNA genes,including 250 upregulated mRNAs,193 upregulated lncRNAs,135 downregulated mRNAs,and 123 downregulated lncRNAs,which were significantly enriched in the Wnt,Hedgehog,and Hippo signaling pathways.(3)Alternative splicing event analysis uncovered 8 differentially expressed variable splicing transcripts,which were all mRNA transcripts,including 2 downregulated and 6 upregulated,and were significantly associated with vascular endothelial growth factor receptor signaling,cell motility,and embryonic development.

Objective: To explore the role and mechanism of epiregulin (EREG) in clear cell renal cell carcinoma (ccRCC)，and to find biomarkers and therapeutic targets for ccRCC. Methods: Based on the data from The Cancer Genome Atlas (TCGA) and Genotype-Tissue Expression (GTEx) databases，the correlation between the expression level of EREG in ccRCC tissues and the clinical staging and survival of ccRCC patients was analyzed. The samples of 6 ccRCC cases treated in the Second Affiliated Hospital of the Air Force Medical University were collected. The expression of EREG was confirmed with immunohistochemistry and quantitative real-time polymerase chain reaction (q-PCR). The effects of EREG overexpression on the proliferation，cell cycle and apoptosis of ACHN cells were verified with CCK-8 and flow cytometry. Finally，the expressions of EREG，epidermal growth factor receptor (EGFR) and the downstream pathway proteins were detected with Western blotting. Results: Based on the databases，it was found that the expression of EREG in ccRCC samples was higher than that in adjacent tissues，and there was a positive correlation with the clinical stage. Survival analysis showed that high expression of EREG was a risk factor affecting the prognosis. The results of immunohistochemical staining and qPCR revealed that EREG was highly expressed in ccRCC. Flow cytometry showed that EREG overexpression promoted the proliferation of ACHN cells，enhanced cell cycle，and inhibited apoptosis. In addition，Western blotting suggested that EREG promoted the expressions of EREG，EGFR and the downstream proteins. Conclusion: The expression of EREG is associated with the prognosis of ccRCC patients. In vitro cell experiments have shown that it can promote the proliferation of ccRCC cells and inhibit their apoptosis，thereby leading to the progression of ccRCC. It can serve as a potential biomarker for prognosis prediction and a drug development target for ccRCC patients.

Erectile dysfunction (ED) is prevalent among men, but its relationship with dietary habits is uncertain. The aim of our study was to assess whether dietary patterns enhance erectile function by reviewing the literature published before August 1, 2022, via PubMed, Web of Science, and EMBASE databases. The data compiled included author details; publication dates, countries, treatments, patient numbers, ages, follow-ups, and clinical trial outcomes, such as ED cases, odds ratios (ORs), confidence intervals (CIs), and International Index of Erectile Function-5 (IIEF-5) scores with means and standard deviations. An analysis of 14 studies with 27 389 participants revealed that plant-based diets (OR = 0.71, 95% CI: 0.66-0.75; P < 0.00001), low-fat diets (OR = 0.27, 95% CI: 0.13-0.53; P = 0.0002), and alternative diets such as intermittent fasting and organic diets (OR = 0.54, 95% CI: 0.36-0.80; P = 0.002) significantly reduced ED risk. High-protein low-fat diets (hazard ratio [HR] = 1.38, 95% CI: 1.12-1.64; P < 0.00001) and high-carb low-fat diets (HR = 0.79, 95% CI: 0.55-1.04; P < 0.00001) improved IIEF-5 scores. Combined diet and exercise interventions decreased the likelihood of ED (OR = 0.49, 95% CI: 0.28-0.85; P = 0.01) and increased the IIEF-5 score (OR = 3.40, 95% CI: 1.69-5.11; P < 0.0001). Diets abundant in fruits and vegetables (OR = 0.97, 95% CI: 0.96-0.98; P < 0.00001) and nuts (OR = 0.54, 95% CI: 0.37-0.80; P = 0.002) were also correlated with lower ED risk. Our meta-analysis underscores a strong dietary-ED association, suggesting that low-fat/Mediterranean diets rich in produce and nuts could benefit ED management.

OBJECTIVE: To evaluate the efficacy and safety of a hospital-made resuscitation pack, a Chinese medicinal herbal compound formula designed to enhance recovery in post-bronchoscopy patients. METHODS: In this randomized, single-blind, placebo-controlled clinical trial, eligible patients were randomly assigned 1:1 to either the treatment or control groups. The patients in the treatment group applied the resuscitation pack, which contained aromatic compounded Chinese herbs. The patients in the control group applied a hospital-made, single herb placebo pack. Packs were placed on the Tiantu (CV 22) acupuncture point for 4 h as soon as the bronchoscopy finished. Efficacy indicators, such as recovery time, patients' symptoms including nausea and dizziness, and adverse events (AEs) were observed and compared. The outcome indices were evaluated at baseline, 1 and 24 h after the bronchoscopy. Subgroup analysis was further performed by patients' age and depth of sedation. RESULTS: When applying generalized estimating equations (GEE) to evaluate the intensity of post-bronchoscopy nausea and vomiting, the intensity was lower in the treatment group (163 cases) compared with the control group (162 cases; 95% CI: 0.004, 0.099, P=0.03]. Also, significantly lower intensity of nausea was observed in the 60-70 years of age subgroup (95% CI: 0.029, 0.169, P=0.006) and deep sedation subgroup (95% CI: 0.002, 0.124; P=0.04). There was no significant difference in dizziness between two groups by GEE (95% CI: -0.134, 0.297; P=0.459). In addition, no serious AEs were observed in either group. CONCLUSIONS Our study found that the resuscitation pack markedly improved patients' symptoms by reducing nausea and vomiting after bronchoscopy without AEs, compared with placebo in the perioperative period.

Objective To explore the clinical efficacy and safety of Beimu Zhizhu Prescription(derived from the modification of Zhizhu Pills)in the treatment of GERC by retrospectively analyzing the clinical data of 297 patients with gastroesophageal reflux cough(GERC).Methods A retrospective cohort study was conducted in a total of 297 patients with GERC of rebellious stomach qi type who were admitted to the Outpatient Department of Wangjing Hospital of China Academy of Chinese Medical Sciences from July 2021 to July 2023.The patients were divided into an exposure group(136 cases)and a non-exposure group(161 cases)according to the medication of Beimu Zhizhu Prescription or not.The exposure group was treated with Beimu Zhizhu Decoction,and the non-exposure group was treated with proton pump inhibitor of Esomeprazole Magnesium Enteric-coated Tablets.A total of 119 pairs of cases were obtained after propensity score matching(PSM)at the ratio of 1 to 1.The changes of salivary pepsin level before and after treatment in the two groups were observed.After two weeks and eight weeks of treatment,the cough response rate and the remission rates for reflux-related symptoms of acid reflux,heartburn,belching and gastric distension were compared between the two groups,and the incidence of adverse reactions was recorded.Results(1)After two weeks of treatment,the comparison of symptom remission rate after PSM showed that the cough response rate and the remission rates for reflux-related symptoms of acid reflux,heartburn,belching and gastric distension in the exposure group were 84.87％(101/119),80.77％(84/104),82.61％(76/92),82.5％(66/80),84.42％(65/77),respectively,and those in the non-exposure group were 73.95％(88/119),72.90％(78/107),70.41％(69/98),65.38％(51/78),64.38％(47/73),respectively.The intergroup comparison showed that the remission rates for all of the symptoms except for acid reflux in the exposure group was significantly superior to that in the non-exposure group(P＜0.05 or P＜0.01).After eight weeks of treatment,the cough response rate and the remission rates for reflux-related symptoms of acid reflux,heartburn,belching,and gastric distension in the exposure group were 94.74％(36/38),91.67％(33/36),91.43％(32/35),93.75％(30/32),94.12％(32/34),respectively,and those in the non-exposure group were 77.78％(35/45),74.42％(32/43),71.43％(30/42),68.42％(26/38),66.67％(24/36),respectively.The intergroup comparison showed that the remission rate of all of the symptoms in the exposure group was significantly superior to that in the non-exposure group(P＜0.05 or P＜0.01).(2)After two weeks of treatment,the comparison of salivary pepsin level after PSM showed that the salivary pepsin level of the exposure group was significantly lower than that before treatment(P＜0.01),while that of the non-exposure group was not significantly decreased(P＞0.05).The decrease of salivary pepsin level in the exposure group was significantly superior to that in the non-exposure group.Statistically significant differences were presented in the post-treatment salivary pepsin level after two weeks of treatment and in the pre-and post-treatment difference of salivary pepsin level between the two groups(P＜0.05 or P＜0.01).(3)There were four cases(2.48％)of adverse reactions in the non-exposure group,while no related adverse reactions occurred in the exposure group.There was no significant difference in the incidence of adverse reactions between the two groups(x2=1.180,P=0.178).Conclusion Beimu Zhizhu Decoction can effectively relieve cough and reflux-related symptoms of acid reflux,heartburn,belching,and gastric distension in patients with GERC of rebellious stomach qi type,reduce the level of salivary pepsin,and has high safety.

Objective To investigate the correlation between the level of N-terminal pro-Brain natriuretic peptide(NT-proBNP)and cardiorespiratory fitness following acute exposure to high altitude.Methods Forty-six subjects were recruited from the Second Affiliated Hospital of Army Medical University in June 2022,including 19 males and 27 females.After completing cardiopulmonary exercise test(CPET),serological detection of myocardial cell-related markers,and multiple metabolites at a plain altitude(300 meters above sea level),all subjects flew to a high-altitude location(3900 meters above sea level).Biomarker testing and CPET were repeated on the second and third days after arrival at high altitude.Changes in serum biomarker and key CPET indicators before and after rapid ascent to high altitude were compared,and the correlation between serum levels of various myocardial cell-related markers and metabolites and high altitude cardiorespiratory fitness was analyzed.Results Compared with the plain altitude,there was a significant decrease in maximal oxygen uptake after rapid ascent to high altitude[(25.41±6.20)ml/(kg.min)vs.(30.17±5.01)ml/(kg.min),P<0.001].Serum levels of NT-proBNP,Epinephrine(E),plasma renin activity(PRA),angiotensin Ⅱ(Ang Ⅱ),angiotensin-converting enzyme 2(ACE2)and leptin(LEP)significantly increased,with all differences being statistically significant(P<0.05)after acute high altitude exposure.In contrast,no statistically significant differences were observed for creatine kinase MB(CK-MB),cardiac troponin I(cTnI),myoglobin(Myo)and norepinephrine(NE)(P>0.05).Correlation analysis showed a significant negative correlation between NT-proBNP at plain altitude(r=-0.768,P<0.001)and at high altitude(r=-0.791,P<0.001)with maximal oxygen uptake at high altitude.Multivariate linear regression analysis indicated that maximal oxygen uptake at plain altitude(t=2.069,P=0.045),NT-proBNP at plain altitude(t=-2.436,P=0.020)and at high altitude(t=-3.578,P=0.001)were independent influencing factors of cardiorespiratory fitness at high altitude.Conclusion Cardiorespiratory fitness significantly decreases after rapid ascent to high altitude,and the baseline NT-proBNP level at plain altitude is closely related to cardiorespiratory fitness at high altitude,making it a potential predictor indicator for high altitude cardiorespiratory fitness.

Objective:To investigate the clinicopathological characteristics of gastrointestinal tumors with SWI/SNF complex deficiency and to perform a prognostic analysis of the patients.Methods:Gastrointestinal tumor cases with SWI/SNF complex deficiency expression diagnosed at the Department of Pathology, Zhongshan Hospital, Fudan University, Shanghai, China from August 2021 to May 2023 were collected. Hematoxylin and eosin (HE) stained slides were reviewed, and immunohistochemical results were analyzed. Clinical and pathological information was recorded, and relevant literature was reviewed.Results:A total of 36 cases of gastrointestinal tumor with loss of SWI/SNF complex expression were identified, including 28 males (77.8%) and 8 females (22.2%). The average age at diagnosis was 70 years (range 48-85 years). Clinical staging showed 3 cases in stage Ⅰ (8.3%), 12 cases in stage Ⅱ (33.3%), 19 cases in stage Ⅲ (52.8%), and 2 cases in stage Ⅳ (5.6%). Complete or partial loss of ARID1A expression was observed in 20 cases (55.6%); complete or partial loss of SMARCA2 expression was observed in 24 cases (66.7%). SMARCA4 exhibited complete loss of expression in 4 cases (11.1%). Eleven cases (30.6%) showed concurrent complete or partial losses of both ARID1A and SMARCA2 expression. Twelve cases (33.3%) had mismatch repair protein deficiency, all of which were characterized by MLH1/PMS2 absence. Mismatch repair protein deficiency was associated with loss of ARID1A expression ( P<0.01). Patients with mismatch repair protein deficiency were also associated with earlier clinical stage and a lower risk of lymph node metastasis compared to the ones with intact mismatch repair proteins ( P<0.05). Conclusions:SWI/SNF complex deficiency in gastrointestinal tumors is associated with dedifferentiation and often accompanied by mismatch repair protein deficiency. Compared to the cases with intact mismatch repair proteins, the cases with defective mismatch repair protein have an earlier clinical stage and a lower risk of lymph node metastasis.
