Objective To analyze the medication rules of Professor LAO Shaoxian in the treatment of gastric stuffiness based on syndrome differentiation.Methods The effective prescriptions for patients with gastric stuffiness treated by Professor LAO Shaoxian from March 2017 to March 2022 were collected,and the general information,chief complaints,diagnosis,syndrome differentiation and prescriptions of patients were extracted.Excel software and the ancient and modern medical records cloud platform(V 2.3.7)were used to construct the prescription database.Data mining function was used to carry out analysis of the syndrome type of prescription,analysis of the frequency and property of Chinese herbs,as well as association rule analysis and cluster analysis.Results A total of 272 prescriptions were included,involving 164 kinds of medicinal herbs.The main traditional Chinese medicine(TCM)syndrome types are damp-heat syndrome and qi stagnation syndrome.The frequency of 25 herbs was more than or equal to 30 times.The representative herbs is Pinellinae Rhizoma Praeparatum,Glycyrrhizae Radix et Rhizoma,Citri Reticulatae Pericarpium,Perillae Caulis and Aucklandiae Radix.The medicinal properties are mainly warm and flat.The medicinal flavors are spicy,bitter and sweet.The drug meridians mainly included the spleen,stomach and lung meridians,followed by the liver meridian.There were 23 core drug pairs obtained by association rules,such as"Aucklandiae Radix-Perillae Caulis","Citri Reticulatae Pericarpium-Perillae Caulis",and"Pinellinae Rhizoma Praeparatum-Citri Reticulatae Pericarpium".Clustering analysis of drugs can be divided into three combinations,which have the effects of regulating qi and relieving distension,resolving dampness,and clearing heat and detoxifying.Conclusion The core prescription of Professor LAO Shaoxian in the treatment of gastric stuffiness is Aucklandiae Radix,Perillae Caulis,Citri Reticulatae Pericarpium,Pinellinae Rhizoma Praeparatum,Glycyrrhizae Radix et Rhizoma,Kaki Calyx,Aurantii Fructus Immaturus and Arecae Pericarpium.It focuses on regulating qi movement of middle jiao and treating spleen and stomach simultaneously.The main therapeutic method is regulating qi and relieving distension.At the same time,attention should be paid to the application of dampness-dispelling and stagnation-removing,heat-clearing and detoxifying drugs.The clinical therapy of Professor LAO Shaoxian on gastric stuffiness is significant,which can be used as a reference for diagnosis and treatment.

Background and purpose:Colorectal cancer(CRC)is one of the major malignant tumors threatening human health worldwide,with long-term high incidence and mortality rate.Potassium channel modulatory factor 1(KCMF1)is a member of the E3 ubiquitin ligase family.It binds to target proteins through the RING domain and participates in the regulation of a variety of biological processes in vivo.However,the function of KCMF1 in CRC remains unclear.This study aimed to investigate the expression level of E3 ubiquitin ligase KCMF1 in colorectal tumor,and to explore the effects of KCMF1 on the proliferation of CRC cells and its underlying molecular mechanism.Methods:The The Cancer Genome Atlas(TCGA)and Genotype-Tissue Expression(GTEx)databases were used to analyze the expression level of KCMF1 in CRC tissues and adjacent tissues and the association between the KCMF1 expression and the prognosis of CRC patients.Furthermore,immunohistochemical staining was performed to detect the protein level of KCMF1 in 90 paired human CRC tissues and adjacent non-tumor tissues.Lentiviral shRNA delivery system was employed to specifically target the KCMF1 gene(shKCMF1)in HCT116 and HCT15 CRC cell lines.The effects of KCMF1 knockdown on cell proliferation,apoptosis and cell cycle distribution were assessed by methyl thiazoyl terazolium(MTT)assay,colony formation assay,Western blot and flow cytometry.Changes in the transcriptional profile in HCT116 cells upon KCMF1 knockdown were identified by RNA sequencing(RNA-Seq),and the affected signaling pathways were evaluated by bioinformatics analysis.Real-time fluorescence quantitative polymerase chain reaction(RTFQ-PCR),Western blot,luciferase reporter assay and cell immunofluorescence assay were utilized to validate the alteration of the affected signaling pathway.Results:The TCGA and GTEx databases and IHC results showed that the mRNA and protein expression levels of KCMF1 in CRC tissues were significantly upregulated compared with adjacent tissues(P＜0.01).KCMF1 expression level was negatively correlated with the survival time of patients with CRC(P＜0.01),and was positively associated with CRC clinical stage(P＜0.05).Compared with control cells,KCMF1 knockdown significantly inhibited the proliferation of HCT116 and HCT15 cells(P＜0.001),induced cell apoptosis(P＜0.001),and led to cell cycle arrest in G1 phase(P＜0.01).RNA-Seq analysis showed that KCMF1 was involved in the regulation of several signaling pathways,including nuclear factor-κB(NF-κB)signaling pathway.KCMF1 knockdown reduced the transcription levels of the target genes of NF-κB signaling pathway,including BCL-XL,XIAP and CIAP(P＜0.05),and suppressed the expression of phosphorylated p65 and nuclear translocation of p65(P＜0.01).Meanwhile,the activity of NF-κB reporter was reduced in tumor cells upon KCMF1 knockdown(P＜0.01).Conclusion:The expression of KCMF1 is significantly upregulated in human CRC tissues and positively associated with advanced clinical stage and poor prognosis.KCMF1 may promote the proliferation of CRC cells by activating the NF-κB signaling pathway.KCMF1 may be a potential new therapeutic target for CRC.

Antimicrobial resistance poses a serious threat to public health and is one of the major challenges worldwide. As global social, economic, and environmental changes lead to increased exposure of populations to antimicrobials, the antimicrobial resistance of pathogens has accelerated and resulted in weakened clinical infection treatment effects. This article reviews the main mechanisms and driving factors of the production and spread of antimicrobial resistance from the perspective of "One Health"and discusses methods and strategies for controlling antimicrobial resistance from multiple dimensions. It also looks forward to the prospects of research and prevention of drug resistance to explore antimicrobial resistance prevention and control strategies based on "One Health".

Objective:To investigate the effects of fasudil hydrochloride(FH) on Rho-associated kinase 2(ROCK2) protein and ferroptosis in hippocampal area during early brain injury in rats with subarachnoid hemorrhage(SAH).Methods:Total 36 SPF grade Sprague-Dawley rats were divided into 3 groups by random number table method: Sham group, SAH group and SAH+ FH (a ROCK2 protein inhibitor) group (FH goup) with 12 rats in each group.SAH animal model was established by internal carotid artery perforation.The rats in FH group were injected intraperitoneally with FH(15 mg/kg) 30 minutes after successful modeling, and rats in Sham group and SAH group were injected intraperitoneally with the same volume of 0.9% sodium chloride solution.Twenty-four hours after the intervention, shuttle box test was used to observe the learning and memory ability of rats.The Fe 2+ content in rat hippocampus tissue was detected by colorimetry, and the protein levels of ROCK2 and ferroptosis-related long-chain acyl-CoA synthetase 4(ACSL4) and glutathione peroxidase 4(GPX4) in hippocampus were detected by immunohistochemistry and Western blot.Statistical analysis was performed by SPSS 20.0 software.One-way ANOVA was used for multigroup comparison, and LSD test was used for further pairwise comparison. Results:(1)In the shuttle box test, there were statistically significant differences in the number of avoidance reactions and avoidance reaction time of rats among the three groups( F=20.348, 22.316, both P<0.05). The number of avoidance reaction in SAH group was less than that in Sham group ((17.92±2.94) times, (27.13±3.48) times, P<0.05), the time of avoidance reaction in SAH group was longer than that in Sham group ((9.15±2.87) s, (3.68±1.09) s, P<0.05), while the number of avoidance reaction in FH group ((21.63±4.11) times) was more than that in SAH group, and the time of avoidance reaction ((6.08±1.76) s) was shorter than that in SAH group (both P<0.05). (2) The colorimetry results showed that there was a statistically significant difference in the content of Fe 2+ in hippocampus of rats among the three groups( F=7.965, P<0.05). The Fe 2+ content in SAH group was significantly higher than that of Sham group((0.091±0.032) nmol/mg, (0.038±0.024) nmol/mg, P<0.05), and the Fe 2+ content in the FH group ((0.065±0.021) nmol/mg) was lower than that of SAH group ( P<0.05). (3) There were significant differences in the number of ROCK2, ACSL4 and GPX4 positive cells in hippocampus of rats among the three groups in immunohistochemistry ( F=7.602, 14.171, 36.077, all P<0.05). The positive cells of ROCK2 and ACSL4 in SAH group ((21.63±4.72), (55.13±19.41)) were significantly higher than those of Sham group ((11.63±3.62), (23.38±3.74)) (both P<0.05), and the positive cells of ROCK2 and ACSL4 in FH group ((15.88±6.64), (44.75±8.29)) were both lower than those of SAH group(both P<0.05), while the number of GPX4 positive cells in SAH group (25.38±6.30) was significantly lower than that of Sham group (60.25±10.36) ( P<0.05), and the number of GPX4 positive cells in FH group (45.13±7.51) was higher than that of SAH group( P<0.05). (4)The results of Western blot showed that there were significant differences in the expression levels of ROCK2, ACSL4 and GPX4 proteins in the hippocampus of rats among the three groups( F=4.812, 12.573, 10.849, all P<0.05). The protein expression levels of ROCK2 and ACSL4 in SAH group were significantly higher than those in Sham group(both P<0.05), and the protein expression levels of ROCK2 and ACSL4 in FH group were lower than those in SAH group (both P<0.05), while the expression level of GPX4 protein in SAH group (0.27±0.09) was significantly lower than that in Sham group( P<0.05), and the expression level of GPX4 protein in FH group was higher than that of SAH group ( P<0.05). Conclusion:FH can inhibit ferroptosis in the hippocampus and improve the learning and memory ability of rats, and the mechanism may be related with down-regulation of ROCK2 protein.

Objective:To analyze the incidence of congenital cleft lip and cleft palate in Shanxi province and its trend from 2010 to 2020.Methods:The clinical data of perinatal infants from 2010 to 2020 were collected from Shanxi Provincial Hospital Monitoring System, and the distribution, prenatal diagnosis, the incidence of cleft lip, cleft palate, and the trend were analyzed.Results:From 2010 to 2020, among 843 457 prenatal infants in Shanxi province, there were 1 264 cases of cleft lip and/or cleft palate with an overall incidence rate of 1 4.99/10 4. Among them 199 cases were cleft palate (15.74%) with an incidence rate of 2.36/10 4; 358 cases were cleft lip (28.33%) with an incidence rate of 4.24/10 4; 707 cases were cleft lip with cleft palate (55.93%) with an incidence rate of 8.38/10 4. The overall incidence of cleft lip and/or cleft palate was significantly decreased from 2010 to 2020 ( χ2=104.04, P<0.001). The incidence of cleft lip in rural area was higher than that in urban areas (19.13/10 4vs. 11.50/10 4, χ2=81.29, P<0.001); the incidence in male infants was higher than that in female infants (16.41/10 4vs. 13.41/10 4, χ2=90.59, P<0.001). There were significant differences in the incidence of cleft lip and cleft palate among different maternal ages ( χ2=58.40, P<0.001); the incidence in maternal age<20 years (21.66/10 4) and 20-<25 years (21.06/10 4) was higher than that of other groups. The proportion of prenatal diagnosis of total cleft lip was 27.85% (352/1 264), which showed an increasing trend ( χ2=6.96, P=0.008). Conclusion:From 2010 to 2020, the incidence of congenital cleft lip and palate in Shanxi province shows a decreasing trend, while the prenatal diagnosis rate shows an increasing trend.

A case is presented involving a patient with a history of pelvic fracture who experienced progressive difficulty in urination following the removal of a urethral catheter. Attempt to retain the catheter was unsuccessful, leading to an ultrasound-guided suprapubic puncture cystostomy. Subsequently, the patient developed persistent abdominal pain, distension, nausea, and vomiting. Analysis of turbid greyish-yellow thin purulent fluid obtained during abdominal paracentesis indicated the presence of peritonitis. Urgent surgical exploration revealed that the diversion tube had passed through the abdominal cavity and into the bladder. The entire abdominal cavity was filled with yellowish-thin purulent fluid. Intraoperatively, the patient presented with worsening hypotension, tachycardia, oliguria, and decreased skin temperature, suggestive of septic shock resulting from peritonitis. Prompt management, including antimicrobial therapy, hemodynamic support, and fluid resuscitation, successfully controlled the infectious symptoms, leading to complete recovery. In clinical practice, the emphasis is often placed on assessing injuries to intra-abdominal organs, whereas awareness and understanding of peritoneal injuries remain limited. As a result, postoperative peritonitis is frequently attributed solely to intra-abdominal organ damage, overlooking the potentially grave consequences of pure peritoneal injury. Therefore, it is imperative to enhance our recognition and knowledge regarding peritoneal injuries, enabling timely diagnosis and treatment to prevent the occurrence of complications.

Serine/arginine-rich splicing factor 7 (SRSF7), a known splicing factor, has been revealed to play oncogenic roles in multiple cancers. However, the mechanisms underlying its oncogenic roles have not been well addressed. Here, based on N⁶-methyladenosine (m⁶A) co-methylation network analysis across diverse cell lines, we find that the gene expression of SRSF7 is positively correlated with glioblastoma (GBM) cell-specific m⁶A methylation. We then indicate that SRSF7 is a novel m⁶A regulator, which specifically facilitates the m⁶A methylation near its binding sites on the mRNAs involved in cell proliferation and migration, through recruiting the methyltransferase complex. Moreover, SRSF7 promotes the proliferation and migration of GBM cells largely dependent on the presence of the m⁶A methyltransferase. The two m⁶A sites on the mRNA for PDZ-binding kinase (PBK) are regulated by SRSF7 and partially mediate the effects of SRSF7 in GBM cells through recognition by insulin-like growth factor 2 mRNA-binding protein 2 (IGF2BP2). Together, our discovery reveals a novel role of SRSF7 in regulating m⁶A and validates the presence and functional importance of temporal- and spatial-specific regulation of m⁶A mediated by RNA-binding proteins (RBPs).

Objective:To describe the baseline characteristics of the subjects enrolled in the China Quantitative CT (QCT) big data program in 2018—2019.Methods:Based on baseline data from the Chinese health big data project from January 2018 to December 2019 from the eligible enrolled population, measurements of bone mineral density (BMD) and visceral adipose tissue (VAT) were performed using Mindways′ QCT Pro Model 4 system. The baseline data of age, gender, regional distribution, height, weight, abdominal circumference, blood pressure, blood routine and blood biochemical tests were analyzed. And the single factor analysis of variance (ANOVA) was used to check the age related trend of BMD and VAT in both genders.Results:After screening the inclusion exclusion criteria and outliers of the main indicators, 86 113 people were enrolled in the project. The enrollment rate was 92.47%, including 35 431 (41.1%) women and 50 682 (58.9%) men, and the ratio of men to women was 1.43. The mean age was (50.3±12.7) years in all the subjects, and it was (50.2±12.8) years and (50.4±12.5) years in men and women, respectively, and there was no statistical difference between the two genders ( P>0.05). Total of 43 833 people were enrolled in east China, it was the largest group by region (50.90%), it was followed by central China (16 434 people, 19.08%), and the number of people enrolled in Northeast China was the lowest (2 914 people, 3.38%). The rate of completing of health information indicators related to the main outcome of the study were all above 70%, and there were significant differences between men and women (all P<0.05). The mean BMD was (139.33±46.76) mg/cm 3 in women, (135.90±36.48) mg/cm 3 in men, which showed a decreasing trend with age in both gender (both P<0.001); the mean intra-abdominal fat area was (116.39±56.23) cm 2 in women, (191.67±77.07) cm 2 in men, and there was an increasing trend with age in both men and women (both P<0.001). Conclusions:There are gender differences in BMD and VAT measured by QCT with different age tendency, and there are gender differences in health information index. Regional factors should also be taken into account for regional differences in the inclusion of data.
