Clinical Experience of External Application of Clearing Heat and Removing Dampness in Relieving Grade 2 to 3 Rash Caused by Programed Cell Death Protein 1 (PD-1)/Programed Cell Death Ligand 1 (PD-L1) Inhibitors: A Single-Center Retrospective Study.

OBJECTIVE: In China, grade 2 to 3 immune-related rash will probably lead to the interruption of immunotherapy. Corticosteroid (CS) is the main treatment, but not always effective. The external application of clearing heat and removing dampness, which is represented by Qing-Re-Li-Shi Formula (QRLSF), has been used in our hospital to treat immune-related cutaneous adverse events (ircAEs) for the last 5 years. The purpose of this study was to discuss its efficacy and safety in the treatment of grade 2 to 3 rash. METHODS: A retrospective study of patients with grade 2 to 3 immune-related rash in our hospital from December 2019 to December 2022 was conducted. These patients received QRLSF treatment. Clinical characteristics, treatment outcome, and health-related quality of life (HrQoL) were analyzed. RESULTS: Thirty patients with grade 2 to 3 rash (median onset time: 64.5 days) were included. The skin lesions of 24 cases (80%) returned to grade 1 with a median time of 8 days. The accompanying symptoms were also improved with median time of 3 to 4 days. The addition of antihistamine (AH) drug didn't increase the efficacy of QRLSF (AH + QRLSF: 75.00% vs QRLSF: 83.33%, P = .66). No significant difference was observed in the efficacy of QRLSF treatment regardless of whether patients had previously received CS therapy (untreated population: 88.24% vs treated population: 69.23%, P = .36). During 1-month follow-up, 2 cases (8.33%) underwent relapses. In terms of HrQoL, QRLSF treatment could significantly reduce the median scores of all domains of Skindex-16, including symptoms (39.58 vs 8.33, P < .0001), emotions (58.33 vs 15.48, P < .0001), functioning (46.67 vs 13.33, P < .0001) and composite (52.60 vs 14.06, P < .0001). CONCLUSION: External application of clearing heat and removing dampness was proven to be an effective and safe treatment for such patients. In the future, high-quality trials are required to determine its clinical application in the field of ircAEs.

SPOP promotes CREB5 ubiquitination to inhibit MET signaling in liver cancer.

Liver cancer is ranked as the sixth most prevalent from of malignancy globally and stands as the third primary contributor to cancer-related mortality. Metastasis is the main reason for liver cancer treatment failure and patient deaths. Speckle-type POZ protein (SPOP) serves as a crucial substrate junction protein within the cullin-RING E3 ligase complex, acting as a significant tumor suppressor in liver cancer. Nevertheless, the precise molecular mechanism underlying the role of SPOP in liver cancer metastasis remain elusive. In the current study, we identified cAMP response element binding 5 (CREB5) as a novel SPOP substrate in liver cancer. SPOP facilitates non-degradative K63-polyubiquitination of CREB5 on K432 site, consequently hindering its capacity to activate receptor tyrosine kinase MET. Moreover, liver cancer-associated SPOP mutant S119N disrupts the SPOP-CREB5 interactions and impairs the ubiquitination of CREB5.This disruption ultimately leads to the activation of the MET signaling pathway and enhances metastatic properties of hepatoma cells both in vitro and in vivo. In conclusion, our findings highlight the functional significance of the SPOP-CREB5-MET axis in liver cancer metastasis.

Network Pharmacology-Based Identification of Key Mechanisms of Xihuang Pill in the Treatment of Triple-Negative Breast Cancer Stem Cells.

Xihuang pill, an approved Chinese medicine formula (state medical permit number. Z11020073), is a commonly used adjuvant drug for cancer patients in China. Xihuang pill has a satisfactory effect in treating breast cancer in clinics, especially triple-negative breast cancer (TNBC), which is the most aggressive type of breast cancer, and finite effective therapies. However, the mechanism of Xihuang pill in treating TNBC remains unclear. The present study aims to explore the pharmacological mechanism of Xihuang pill in treating advanced TNBC. We identified the main chemical components of Xihuang pill by using HPLC-Q-TOF-MS/MS. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) analysis shows that serum containing Xihuang pill (XS) had no obvious killing effect on any subtype of breast cancer cells, but it inhibited mammosphere colony formation of two TNBC cell lines (4T1 and HCC1806 cells) and could enhance the inhibitory effect of paclitaxel (PTX) on the proliferation of 4T1 and HCC1806 cells when combined with PTX. Seventy-six active compounds in Xihuang pill, their 300 protein targets, and 16667 TNBC stem cell-related genes were identified. The drug-herb-active compound-target gene-disease network and enrichment analyses were constructed with 190 overlapping candidate targets. Through text mining and molecular docking, the target gene NR3C2 and its active compound naringenin were selected for further validation. According to the TCGA database, we observed that a high expression of NR3C2 promoted a higher survival probability regarding overall survival (OS). In vitro experiments indicated that naringenin presented an identical effect to XS, possibly by regulating the NR3C2 expression. Overall, this study explored the effect of Xihuang pill in treating advanced TNBC cells and showed that naringenin, which is the key active compound of Xihuang pill, could lessen the stemness of TNBC cells to produce a synergistic effect on PTX by regulating the NR3C2 gene.

Profiles of Bacillus spp. Isolated from the Rhizosphere of Suaeda glauca and Their Potential to Promote Plant Growth and Suppress Fungal Phytopathogens.

Members of the genus Bacillus are known to play an important role in promoting plant growth and protecting plants against phytopathogenic microorganisms. In this study, 21 isolates of Bacillus spp. were obtained from the root micro-ecosystem of Suaeda glauca. Analysis of the 16S rRNA genes indicated that the isolates belong to the species Bacillus amyloliquefaciens, Bacillus velezensis, Bacillus subtilis, Bacillus pumilus, Bacillus aryabhattai and Brevibacterium frigoritolerans. One of the interesting findings of this study is that the four strains B1, B5, B16 and B21 are dominant in rhizosphere soil. Based on gyrA, gyrB, and rpoB gene analyses, B1, B5, and B21 were identified as B. amyloliquefaciens and B16 was identified as B. velezensis. Estimation of antifungal activity showed that the isolate B1 had a significant inhibitory effect on Fusarium verticillioides, B5 and B16 on Colletotrichum capsici (syd.) Butl, and B21 on Rhizoctonia cerealis van der Hoeven. The four strains grew well in medium with 1-10% NaCl, a pH value of 5-8, and promoted the growth of Arabidopsis thaliana. Our results indicate that these strains may be promising agents for the biocontrol and promotion of plant growth and further study of the relevant bacteria will provide a useful reference for the development of microbial resources.

Clinical application of combined detection of SARS-CoV-2-specific antibody and nucleic acid.

BACKGROUND: The global outbreak of human severe acute respiratory syndrome coronavirus (SARS-CoV)-2 infection represents an urgent need for readily available, accurate and rapid diagnostic tests. Nucleic acid testing of respiratory tract specimens for SARS-CoV-2 is the current gold standard for diagnosis of coronavirus disease 2019 (COVID-19). However, the diagnostic accuracy of reverse transcription polymerase chain reaction (RT-PCR) tests for detecting SARS-CoV-2 nucleic acid may be lower than optimal. The detection of SARS-CoV-2-specific antibodies should be used as a serological non-invasive tool for the diagnosis and management of SARS-CoV-2 infection. AIM: To investigate the diagnostic value of SARS-CoV-2 IgM/IgG and nucleic acid detection in COVID-19. METHODS: We retrospectively analyzed 652 suspected COVID-19 patients, and 206 non-COVID-19 patients in Wuhan Integrated TCM and Western Medicine Hospital. Data on SARS-CoV-2 nucleic acid tests and serum antibody tests were collected to investigate the diagnostic value of nucleic acid RT-PCR test kits and immunoglobulin (Ig)M/IgG antibody test kits. The χ2 test was used to compare differences between categorical variables. A 95% confidence interval (CI) was provided by the Wilson score method. All analyses were performed with IBM SPSS Statistics version 22.0 (IBM Corp., Armonk, NY, United States). RESULTS: Of the 652 suspected COVID-19 patients, 237 (36.3%) had positive nucleic acid tests, 311 (47.7%) were positive for IgM, and 592 (90.8%) were positive for IgG. There was a significant difference in the positive detection rate between the IgM and IgG test groups (P < 0.001). Using the RT-PCR results as a reference, the specificity, sensitivity, and accuracy of IgM/IgG combined tests for SARS-CoV-2 infection were 98.5%, 95.8%, and 97.1%, respectively. Of the 415 suspected COVID-19 patients with negative nucleic acid test results, 366 had positive IgM/IgG tests with a positive detection rate of 88.2%. CONCLUSION: Our data indicate that serological IgM/IgG antibody combined test had high sensitivity and specificity for the diagnosis of SARS-CoV-2 infection, and can be used in combination with RT-PCR for the diagnosis of SARS-CoV-2 infection.

[Analysis of medication regularity and pharmacodynamic characteristics of traditional Chinese medicine treatment in 444 severe cases of COVID-19].

The coronavirus disease 2019(COVID-19) is developing rapidly and posing great threat to public health. There is no effective intervention for the severe patients, and their prognosis is poor. It is worth noting that in the fight against COVID-19, China has always put equal emphasis on both Chinese and Western medicine. Traditional Chinese medicine has played an important role in the whole process. It is of great significance to discuss the rules and characteristics of the prescription of traditional Chinese medicine in the treatment of COVID-19. In this study, information was collected from 444 severe COVID-19 patients who were admitted to a hospital designated to treat patients with severe COVID-19 in Wuhan before March 20, 2020. We collected traditional Chinese medicine prescriptions for patients with severe COVID-19, referred to Chinese Pharmacopoeia to standardize the names of traditional Chinese medicine, and extract the property, flavor and channel tropism of traditional Chinese medicines to analyze the rules of the prescriptions. IBM SPSS Modeler 18.0 software was used to conduct correlation analysis of traditional Chinese medicine. Effective traditional Chinese medicines against COVID-19 was identified by the TCMATCOV platform. In the end, 1 532 effective prescriptions were included. Among them, the high-frequency drugs are Poria, Astragali Radix, Pogostemonis Herba, Armeniacae Semen Amarum, Atractylodis Macrocephalae Rhizoma, Pinelliae Rhizoma, Glycyrrhizae Radix et Rhizoma, Magnoliae Officinalis Cortex, Ephedrae Herba, Cinna-momi Ramulus. Most of the drugs have the following functions: resolving dampness, replenishing deficiency, resolving phlegm, cough, and asthma. The core combinations are Pogostemonis Herba-Poria, Astragali Radix-Pogostemonis Herba-Poria, Amomi Fructus-Poria, Amomi Fructus-Pogostemonis Herba, Amomi Fructus-Astragali Radix. The majority of the medicines are with cold and warm properties, and the proportions are 41.03% and 38.46%, respectively. The medicinal flavors are mainly concentrated in sweet and bitter, and the proportions are 34.71% and 30.58%, respectively. The meridian of the drug is more into the lung, stomach and spleen, with lung accounting for 22.87%. From the analysis of high-frequency drugs to the core combinations, one can see that the main treatment principle for severe COVID-19 is to remove internal and external dampness, protect the spleen and stomach, remove evil energy, and support righteousness. TCMATCOV platform was used to calculate the network disturbances of the high-frequency drugs. It was found that the traditional Chinese medicine with a high disturbance score accounted for a high proportion of the classic anti-COVID-19 prescriptions used by clinicians. Among them, the drugs with top scores are Ephedrae Herba, Citri Reticulatae Pericarpium, Eupatorii Herba, Platycodonis Radix, Cinnamomi Ramulus, Astragali Radix, Magnoliae Officinalis Cortex, Atractylodis Macrocephalae Rhizoma, Pogostemonis Herba, Scutellariae Radix. After a further exploration of the action targets, it was showed that disease-specific factor TNF was the target of the above ten drugs, and traditional Chinese medicine can exert anti-inflammatory and immune-modulating effects.

Use of tunnel endoscopy for diagnosis of obscure submucosal esophageal adenocarcinoma: A case report and review of the literature with emphasis on causes of esophageal stenosis.

BACKGROUND: The tunnel endoscopic technique is the treatment of choice for submucosal tumors. However, the use of tunnel endoscopy to diagnose adenocarcinoma of the esophagus originating from the submucosa has not been well studied. CASE SUMMARY: A 74-year-old man who presented with dysphagia for half a year underwent a series of checks, such as gastroendoscopy, X-ray contrast examination of the upper digestive tract, endoscopic ultrasonography, high-resolution esophageal manometry, and positron emission computed tomography. It should be noted that the stenosis of the esophagus was too narrow for endoscopic ultrasound-guided fine needle aspiration. The cause remained undiagnosed. Eventually, the tunnel endoscopic technique was perform for the pathological examination in the submucosa and the final diagnosis was adenocarcinoma of the esophagus. The patient and family members chose expectant treatment due to the patient's age and the high costs of surgical treatment. CONCLUSION: Tunnel endoscopy could be used to diagnose tumors. Moreover, we review the literature to provide guidance regarding the causes of esophagostenosis.

[Effect of Fuzi Lizhong decoction in reducing liver injury of rats with non-alcoholic fatty liver via activating AMPK and suppressing NF-κBp65 pathway].

To investigate the protective effect and relevant mechanism of Fuzi Lizhong decoction (FZLZD) on liver of rats with non-alcoholic fatty liver disease (NAFLD), totally 32 male SPF Wistar rats were randomly divided into 4 groups: control group, model group, Yishanfu (YSF) group (200 mg·kg⁻¹·d⁻¹) and FZLZD group (10 g·kg⁻¹·d⁻¹), with 8 rats in each group. Rat model of NAFLD was prepared through the intragastric administration with fat emulsion for 4 weeks. After the successful modeling, rats in each administration group were continuously administered for 4 weeks. After 8 weeks, the rats in each group were put to death, and the pathological changes in liver tissue were detected by HE staining. Automatic biochemical analyzer was used to detect fasting serum lipid levels (T-Chol, TG, LDL-C, HDL-C) and liver functions (ALT, TP, ALB) of rats in each group. The rat liver index was calculated by weighing method. Enzyme-linked immunosorbent assay (ELISA) was used to detect the secretion of inflammatory cytokines TNF-α and IL-6 in liver tissue. Real-time quantitative PCR (qRT-PCR) was used to detect the mRNA expressions of fat metabolism-related factors SREBP-1c and FASN in liver tissue. Western blot was used to detect the p-AMPK and p-NF-κBp65 protein expressions in liver tissue. The results of HE staining showed that compared with the control group, the pathological changes in liver tissue in the model group rats were obvious; specifically, the outline of hepatic lobule was unclear, the hepatic cells showed diffuse steatosis of adipose tissue, and were accompanied by inflammatory infiltration, nuclear condensation, coloring deep; compared with the model group, liver lesions of all of the treatment groups were significantly alleviated; especially, the FZLZD group showed the most significant degree of remission. The results of serum test showed that the levels of serum lipids (T-Chol, TG, LDL-C, HDL-C), liver functions (ALT, TP, ALB) and liver index in model group were significantly higher than those in control group (P<0.01); compared with the model group, the indexes of serum lipid and liver function of rats in each treatment group were significantly decreased (P<0.01), and those in FZLZD group were significantly decreased (P<0.05), while those in YSF group were not significantly changed. The results of ELISA and qRT-PCR showed that compared with the control group, the secretion levels of TNF-α, IL-6 and the mRNA levels of SREBP-1c and FASN in the liver tissue of model group rats were significantly increased (P<0.01); compared with model group, the secretion levels of TNF-α, IL-6 and the mRNA levels of SREBP-1c, FASN in liver tissue of rats in each treatment group were significantly decreased (P<0.01); compared with YSF group, the secretion levels of TNF-α and IL-6 and the mRNA levels of SREBP-1c and FASN in FZLZD group were significantly different (P<0.01). Western blotting showed that compared with the model group, the protein expression of p-AMPK in liver tissue of rats in FZLZD group was significantly increased (P<0.01), while the protein expression of p-NF-κBp65 was significantly decreased (P<0.01). FZLZD can significantly improve hepatic pathological changes, reduce serum lipid levels, promote liver function and liver index in NAFLD rats, which may be associated with the activation of the AMPK pathway and thereby the inhibition of the expressions of SREBP-1c and FASN, and the inhibition of the NF-κBp65 pathway and thereby the reduction of the release of inflammatory factors.

[Effects of three Wenyang Jianpi Tang on cell proliferation and apoptosis of nonalcoholic fatty liver cells].

To investigate the effects of Sijunzi Tang, Lizhong Tang and Fuzi Lizhong Tang on the cell proliferation and apoptosis of nonalcoholic fatty liver cells through the nonalcoholic fatty liver cell model established by inducing L02 cells with oleic acid. Different concentrations of oleic acid were added into L02 cells to induce the nonalcoholic fatty liver cell model. Oil red O staining was used to observe fatty droplets of fatty liver cells. Automatic biochemical analyzer was used to detect the levels of aspartic transaminase(AST), alanine aminotransferase(ALT), total cholesterol(TC), and triglyceride(TG) in the cell supernatants. There were five groups, namely normal group, model group, model and Sijunzi Tang group, model and Lizhong Tang group, and model and Fuzi Lizhong Tang group. The cell proliferation and apoptosis of the five groups were detected by MTT colorimetry test and flow cytometer. The expressions of PCNA, cleaved caspase-3, cleaved caspase-8, cleaved caspase-9, Bax and Bcl-2 proteins of the five groups were detected by Western blot. The oil red O staining results showed that the optimum concentration of oleic acid that was used to induce nonalcoholic fatty liver cell models was 80 mg•L-1. The levels of AST, ALT, TC and TG in the nonalcoholic fatty liver cell supernatants were higher than that in normal liver cell supernatants(P<0.01). MTT colorimetry test and flow cytometer results showed that all of Sijunzi Tang, Lizhong Tang and Fuzi Lizhong Tang could effectively promote the cell proliferation, and inhibit the cellular apoptosis of nonalcoholic fatty liver cells(P<0.01). And Fuzi Lizhong Tang showed the best effect. Western blot results showed that Sijunzi Tang, Lizhong Tang and Fuzi Lizhong Tang could down-regulate the expressions of cleaved caspase-3, cleaved caspase-8, cleaved caspase-9 and Bax proteins, and up-regulate the expressions of PCNA and Bcl-2 proteins of nonalcoholic fatty liver cells. And Fuzi Lizhong Tang showed the best effect. In conclusion, all of Sijunzi Tang, Lizhong Tang and Fuzi Lizhong Tang could effectively promote the cell proliferation, and inhibit the cellular apoptosis of nonalcoholic fatty liver cells. And Fuzi Lizhong Tang showed the best effect. The pharmacodynamic mechanism may be related to the expressions of key factors in pathways related with proliferation and apoptosis mediated by the three decoctions.

[Colonization of grape leaves by endophytic Bacillus subtilis JL4 and its control of grape downy mildew]. / å† ç”Ÿæž¯è‰èŠ½å­¢æ†èŒJL4åœ¨è‘¡è„å¶ä¸Šçš„å®šæ®–åŠå ¶å¯¹è‘¡è„éœœéœ‰ç— çš„é˜²æ²».

In order to understand the colonization pattern of Bacillus subtilis JL4 both on and inside grape leaves, and its control of grape downy mildew, a shuttle vector pGFP78, carrying the GFP gene, was transformed into B. subtilis JL4, and a GFP-labelled transformant designated as JL4-gfp was obtained successfully. The stability of the marker and antagonistic activity to Plasmopara viticola of JL4-gfp were tested. JL4-gfp was spray inoculated on grape leaves in a vine yard and colonization of the leaves was investigated by dilution plating on selective medium. Leaves treated with JL4-gfp were collected and taken to the laboratory for inoculation of a sporangial suspension of P. viticola, to determine its control effect on grape downy mildew. The green fluorescence of the marked strain was stable for at least 10 subcultures, and JL4-gfp maintained wild type antagonistic activity against P. viticola. JL4-gfp was recovered from the grape leaves by dilution plating on medium supplemented with antibiotics. Numbers recovered from the leaf surface of grape leaves were 3.6×105, 2.7×105 and 3.1×103 CFU·g-1 at 0, 3 and 7 days after inoculation, and the population density inside the leaf tissue reached a maximum of 9.6×104 CFU·g-1 at 3 days after inoculation, but could not be recovered after 14 days. The efficiency of downy mildew control by the marked strain was more than 88.0% at 3 days after inoculation, but no significant control effect was observed after 7 days. Our results suggested that there was a positive correlation between the JL4-gfp population density and control efficiency of grape downy mildew, and a threshold colonization level at 105 CFU·g-1 was a prerequisite for this Bacillus strain to present efficient control effects.

[Efficacy of tongfu mixture for treating post-ERCP pancreatitis: a clinical study].

OBJECTIVE: To observe the clinical efficacy of Tongfu Mixture (TM) for post-ERCP pancreatitis (PEP). METHODS: Totally 54 PEP patients were randomly assigned to the control group (treated by routine therapy, 26 cases) and the TM treatment group (treated by TM, 28 cases). Clinical indices including the alleviation time of abdominal pain/distention, gastrointestinal function recovery time, and the post-surgical length of stay were observed. Blood amylase (AMY), C-reactive protein (CRP), plasma endotoxin (PLS), TNF-alpha, and IL-6 were detected before surgery, 12 h, 48 h, and 96 h after surgery. RESULTS: The alleviation time of abdominal pain/distention, the gastrointestinal function recovery time, and the post-surgical length of stay were obviously shorter in the TM treatment group than those in the control group (P < 0.05). The recovery of AMY and CRP were better in the TM treatment group than in the control group at post-operative 48 h and 96 h (P < 0.05). The levels of LPS, TNF-alpha, and IL-6 were lower in the TM group than in the control group at post-operative 96 h (P < 0.05). CONCLUSION: TM showed better clinical efficacy and could significantly decrease the post-surgical length of stay. post-ERCP pancreatitis; integrative medicine; Tongfu Mixture

Clinical trial with traditional Chinese medicine intervention ''tonifying the kidney to promote liver regeneration and repair by affecting stem cells and their microenvironment'' for chronic hepatitis B-associated liver failure.

AIM: To study the clinical efficacy of traditional Chinese medicine (TCM) intervention "tonifying the kidney to promote liver regeneration and repair by affecting stem cells and their microenvironment" ("TTK") for treating liver failure due to chronic hepatitis B. METHODS: We designed the study as a randomized controlled clinical trial. Registration number of Chinese Clinical Trial Registry is ChiCTR-TRC-12002961. A total of 144 patients with liver failure due to infection with chronic hepatitis B virus were enrolled in this randomized controlled clinical study. Participants were randomly assigned to the following three groups: (1) a modern medicine control group (MMC group, 36 patients); (2) a "tonifying qi and detoxification" ("TQD") group (72 patients); and (3) a "tonifying the kidney to promote liver regeneration and repair by affecting stem cells and their microenvironment" ("TTK") group (36 patients). Patients in the MMC group received general internal medicine treatment; patients in the "TQD" group were given a TCM formula "tonifying qi and detoxification" and general internal medicine treatment; patients in the "TTK" group were given a TCM formula of "TTK" and general internal medicine treatment. All participants were treated for 8 wk and then followed at 48 wk following their final treatment. The primary efficacy end point was the patient fatality rate in each group. Measurements of various virological and biochemical indicators served as secondary endpoints. The one-way analysis of variance and the t-test were used to compare patient outcomes in the different treatment groups. RESULTS: At the 48-wk post-treatment time point, the patient fatality rates in the MMC, "TQD", and "TTK" groups were 51.61%, 35.38%, and 16.67%, respectively, and the differences between groups were statistically significant (P < 0.05). However, there were no significant differences in the levels of hepatitis B virus DNA or prothrombin activity among the three groups (P > 0.05). Patients in the "TTK" group had significantly higher levels of serum total bilirubin compared to MMC subjects (339.40 µmol/L ± 270.09 µmol/L vs 176.13 µmol/L ± 185.70 µmol/L, P = 0.014). Serum albumin levels were significantly increased in both the "TQD" group and "TTK" group as compared with the MMC group (31.30 g/L ± 4.77 g/L, 30.72 g/L ± 2.89 g/L vs 28.57 g/L ± 4.56 g/L, P < 0.05). There were no significant differences in levels of alanine transaminase among the three groups (P > 0.05). Safety data showed that there was one case of stomachache in the "TQD" group and one case of gastrointestinal side effect in the "TTK" group. CONCLUSION: Treatment with "TTK" improved the survival rates of patients with liver failure due to chronic hepatitis B. Additionally, liver tissue was regenerated and liver function was restored.
