Hepatic encephalopathy is a difficult and critical disease with rapid progression and limited treatment methods in the field of liver disease， and it is urgently needed to make breakthroughs in its pathogenesis. Selection of appropriate prevention and treatment strategies is of great importance in delaying disease progression and reducing the incidence and mortality rates. This article reviews the theory of “turbid toxin pathogenesis” and related prevention and treatment strategies for hepatic encephalopathy in traditional Chinese medicine/Zhuang medicine， proposes a new theory of “turbid toxin pathogenesis”， analyzes the scientific connotations of “turbid”， “toxin”， and the theory of “turbid toxin pathogenesis”， and constructs the “four-step” prevention and treatment strategies for hepatic encephalopathy， thereby establishing the new clinical prevention and treatment regimen for hepatic encephalopathy represented by “four prescriptions and two techniques” and clarifying the effect mechanism and biological basis of core prescriptions and techniques in the prevention and treatment of hepatic encephalopathy， in order to provide a reference for the prevention and treatment of hepatic encephalopathy.

[Objective] To compare the clinical efficacy and safety of flexible ureteroscope lithotripsy (FURL) combined with flexible vacuum-assisted urethral access sheath (FV-UAS) and traditional UAS in the treatment of 1-2 cm lower renal calyceal stones, so as to provide reference for clinical practice. [Methods] Clinical data of 157 patients with 1-2 cm lower renal calyceal stones treated with FURL during Mar.2021 and Oct.2023 were retrospectively analyzed, including 80 treated with traditional UAS, and 77 with FV-UAS.General and clinical information of the two groups were compared. [Results] The immediate stone-free rate (SFR) (84.4% vs.67.5%, P=0.013) and final SFR (88.3% vs. 75.0%, P=0.032) of the FV-UAS group were significantly higher than those of the traditional UAS group, with significant difference.The incidence of postoperative complications such as fever, renal colic, and perirenal hematoma was significantly higher in the traditional UAS group than in the FV-UAS group (15.0% vs.5.2%, P=0.042). After treatment with anti-infective and analgesic drugs, both groups were improved, and no severe sepsis or septic shock occurred after surgery.The hospitalization expenses of the FV-UAS group were significantly lower than those of the traditional UAS group [ (18 341±1519)yuan vs.(19 152±1826)yuan, P=0.003]. [Conclusion] Compared to the traditional UAS, the combination of FURL and FV-UAS for the 1-2 cm lower renal calyceal stones has a high SFR and low incidence of complications.Patients experience less pain, recover faster and spend less.It's a new treatment option for inferior calyceal calculi.

Epidermal growth factor receptor (EGFR) exon 20 mutations represent a rare subset of genetic alterations in non-small cell lung cancer (NSCLC). Among them, the complex mutation H773_V774delinsLM is exceedingly uncommon, accounting for only 0.2%-1% of all EGFR mutations. It is currently believed that rare EGFR mutations are generally resistant to the first- and second-generation EGFR-tyrosine kinase inhibitors (EGFR-TKIs). Although the third-generation EGFR-TKIs have shown some efficacy in certain rare mutations, clinical evidence regarding their use in NSCLC patients with the H773_V774delinsLM mutation remains sparse, and their efficacy and safety are yet to be clarified. Here, we present the first documented case of a patient with EGFR H773_V774delinsLM-mutant lung adenocarcinoma who experienced remarkable tumor regression following treatment with furmonertinib. This case highlights the potential utility of furmonertinib in treating patients with this rare EGFR mutation and may provide valuable insight into emerging treatment strategies for similarly affected patients.

This study aimed to evaluate the efficacy and safety of combining albumin-bound paclitaxel (abpaclitaxel) and anlotinib for ovarian cancer. In this study, 44 patients diagnosed with platinum-resistant ovarian cancer were enrolled. Patients received ab-paclitaxel along with anlotinib until disease progression or intolerable toxicity. Efficacy was assessed according to RECIST 1.1 criteria or Rustin's criteria. The primary endpoint was the investigator-evaluated objective response rate (ORR). 44 patients were enrolled between January 2021 and March 2023 with a median age of 49 years. Twenty-nine had measurable lesions and 15 had non-measurable lesions. Overall, the investigator-evaluated ORR was 56.8% (25/44; 95% CI 0.411-0.713) in intention-to-treat population and 58.1% (25/43; 95% CI 0.422-0.726) in per-protocol population. The median progression-free survival was 9.8 months, and the median duration of response was 7.4 months. For safety, grade 3/4 adverse events (AEs) included leukopenia, gum pain, hypertension, and hand-foot syndrome. The response rates were 55.0% (11/20) in patients with previous use of antiangiogenic reagents and who had previous use of PARP inhibitors. The combination of ab-paclitaxel and anlotinib showed promising anti-tumor activity and a manageable safety profile in platinum-resistant ovarian cancer. Patients with previous use of antiangiogenic drugs or PARP inhibitors still benefited from this protocol.

Objective To investigate the effect and mechanism of Feixin Decoction(Astragali Radix,Pericae Semen,Carthami Flos,Descurainiae Semen Lepidii Semen,Paeoniae Radix Rubra,etc.)on monocrotaline-induced pulmonary arterial hypertension(PAH)rats based on peroxisome proliferator-activated receptor-γ/nuclear factor-κB(PPAR-γ/NF-κB)signaling pathway.Methods Forty-eight male SD rats were randomly divided into normal group,model group,Sildenafil group(0.025 g·kg-1)and low-,medium-and high-dose of Feixin Decoction groups(11.7,23.4,46.8 g·kg-1).PAH rat model was established by single intraperitoneal injection of monocrotaline solution(60 mg·kg-1).After 1 hour of modeling,the rats were given intragastric administration once a day for 28 days.Hemodynamic and echocardiographic parameters including right ventricular systolic pressure(RVSP),mean pulmonary artery pressure(mPAP),right ventricular hypertrophy index(RVHI),pulmonary artery acceleration time(PAAT),pulmonary artery ejection time(PET),tricuspid annular plane systolic excursion(TAPSE),right ventricular internal diameter(RVIDd)and right ventricular anterior wall thickness(RVAWT)were measured in each group.The pathological changes of pulmonary arterioles were observed by HE staining.The expression level of α-smooth muscle actin(α-SMA)in rat pulmonary artery was detected by immunofluorescence.The levels of plasma interleukin-1β(IL-1β),IL-6 and tumor necrosis factor-α(TNF-α)were detected by ELISA.The expression levels of PPAR-γ/NF-κB signaling pathway-related proteins were detected by immunohistochemistry and Western Blot.Results Compared with the normal group,the RVSP,mPAP,RVHI,RVIDd and RVAWT of the model group were significantly increased(P＜0.01).PAAT,PAAT/PET and TAPSE were significantly decreased(P＜0.01).The wall of pulmonary arterioles was significantly thickened,and the percentage of wall thickness of pulmonary arterioles to vascular diameter and the percentage of vascular wall area to total cross-sectional area of pulmonary arterioles were significantly increased(P＜0.01).The positive expression rate of α-SMA protein in pulmonary artery was significantly increased(P＜0.01).The levels of plasma IL-1β,IL-6 and TNF-α were significantly increased(P＜0.01).The positive expression rate of PPAR-γ protein in lung tissue was significantly decreased(P＜0.01),and the positive expression rate of NF-κB protein was significantly increased(P＜0.01).The protein expressions of PPAR-γ and IκB-α in lung tissue were significantly down-regulated(P＜0.01).The protein expression ratio of p-NF-κB/NF-κB was significantly increased(P＜0.01).Compared with the model group,RVSP,mPAP,RVHI,RVIDd and RVAWT in each administration group were significantly decreased(P＜0.05,P＜0.01),while PAAT,PAAT/PET and TAPSE were significantly increased(P＜0.05,P＜0.01).The thickness of the vascular wall was significantly reduced,and the percentage of the wall thickness of the pulmonary arterioles to the diameter of the blood vessels and the percentage of the vascular wall area to the total cross-sectional area of the small arteries were significantly reduced(P＜0.05,P＜0.01).The positive expression rate of α-SMA protein in pulmonary artery was significantly decreased(P＜0.05,P＜0.01).The plasma levels of IL-1β,IL-6 and TNF-α were significantly decreased(P＜0.05,P＜0.01).The positive expression rate of PPAR-γ protein in lung tissue was significantly increased(P＜0.05,P＜0.01),and the positive expression rate of NF-κB protein was significantly decreased(P＜0.05,P＜0.01).The protein expression of PPAR-γ in lung tissue was significantly up-regulated(P＜0.05,P＜0.01),and the protein expression ratio of p-NF-κB/NF-κB was significantly decreased(P＜0.01).The protein expression of IκB-α in the lung tissue of rats in the high-dose group of Feixin Decoction was significantly up-regulated(P＜0.01).Conclusion Feixin Decoction can improve pulmonary artery pressure,right ventricular dysfunction and pulmonary vascular remodeling in PAH rats induced by monocrotaline.The mechanism may be related to the regulation of PPAR-γ/NF-κB signaling pathway to inhibit inflammatory response.

[Objective] To explore the efficacy of disposable flexible ureteroscopic lithotripsy (FURL) with flexible vacuum-assisted ureteral access sheath (FV-UAS) in the treatment of 2-3 cm upper urinary tract stones, so as to provide reference for the treatment selection. [Methods] Clinical data of 178 patients with upper urinary tract stones who received FURL or minimally invasive percutaneous nephrolithotomy (MPCNL) at our hospital during Apr. 2022 and Oct. 2023 were retrospectively analyzed. The patients were divided into FV-UAS group (n=90, received FV-UAS combined with diaposable FURL treatment) and MPCNL group (n=88, received MPCNL). The general information, perioperative data, and postoperative stone-free rate (SFR) of the two groups were compared. [Results] All operations were successfully completed. The operation time was significantly longer in the FV-UAS group than in the MPCNL group [(66.5±6.7) min vs. (63.9±7.4) min, P=0.015]. However, the intraoperative hemoglobin reduction [(7.3±3.1)g/L vs.(11.4±5.9)g/L], postoperative hospital stay (P<0.001) [(2.2±0.7)d vs.(5.4±1.3)d], and visual analogue score (VAS) [(2.7±0.9)vs.(5.6±1.1)] were significantly lower in the FV-UAS group than in the MPCNL group (P<0.001). The incidence of persistent gross hematuria was significantly higher in the MPCNL group than in the FV-UAS group (12.5% vs. 3.3%, P=0.023). The FV-UAS group had a similar postoperative immediate (83.3%) and final SFR (95.6%) to those of the MPCNL group (89.8%, 96.6%, P>0.05). [Conclusion] The combination of FURL with FV-UAS for 2-3 cm upper urinary tract stones has a higher SFR and a lower complication rate.Patients experience endurable pain and fast recovery, which is worth promoting and applying in clinical practice.

In recent years,the morbidity and mortality of hepatocellular carcinoma(HCC)have been increasing worldwide,and the treatment strategies for HCC are still insufficient,which highlights the importance of exploring the pathogenesis and progression of HCC.Transient receptor potential(TRP)pathway is an important non-selective cation pathway,which is closely related to inflammatory response and sensory conduction.At present,a number of studies have shown that TRP pathway is also involved in the occurrence and development of HCC,inducing HCC invasion and migration.However,the overall potential mechanism and possible signal transduction pathways of TRP pathway in HCC remain unclear.Therefore,this article discusses the abnormal expression of TRP pathway in HCC,and reviews the key biological events of TRP pathway involved in the formation and progression of HCC,such as chronic liver inflammation-fibrosis progression,HCC cell proliferation,migration,apoptosis and HCC stem cell generation,and looks forward to its application prospect in HCC treatment.The aim is to better un-derstand the significance of TRP pathway in HCC,help to find new therapeutic targets and effective drugs,and open up a new situation for future clinical treatment.

BACKGROUND:Rotator cuff muscle degeneration(muscle atrophy,fibrosis and fatty infiltration)is a common condition after rotator cuff tears,which seriously affects shoulder function and surgical outcomes.Ginsenoside Rg1 has biological effects such as anti-oxidation,anti-apoptosis and lipid-lowering.However,the effect of ginsenoside Rg1 on muscle degeneration after rotator cuff tear has not been reported. OBJECTIVE:To investigate the effect of ginsenoside Rg1 on muscle degeneration after massive rotator cuff tear in mice. METHODS:Sixty C57BL/6J mice were randomly divided into sham group,model group,ginsenoside Rg1 low dose group and ginsenoside Rg1 high dose group,with 15 mice in each group.The skin of the right shoulder of mice in the sham group was cut and sutured.Massive rotator cuff tear mouse models of the right shoulder were established in the other three groups.Supraspinatus tendon and suprascapular nerve compression were administrated.Mice in the sham and model groups were intraperitoneally injected with 0.5 mL of saline after operation,while those in the ginsenoside Rg1 low and high dose groups were intraperitoneally injected with ginsenoside Rg1 30 and 60 mg/kg respectively,once a day,for 6 weeks.Mice were assessed for limb function by gait analysis the day after the last injection.After euthanasia,the supraspinatus muscle on the operated side was taken to measure the muscle atrophy rate and muscle contractility.Muscle tissue was stained with oil red O and Masson.RT-PCR was used to detect the expression of atrophy,fibrosis,and fatty infiltration related genes. RESULTS AND CONCLUSION:Compared with the model group,low-and high-dose ginsenoside Rg1 significantly increased paw print area and step length(P<0.05).Compared with the model group,low-and high-dose ginsenoside Rg1 significantly increased myofiber cross-sectional area and supraspinatus contractility(P<0.05),and significantly decreased wet muscle mass reduction ratio,fatty infiltration area ratio,and collagen fiber area ratio(P<0.05).Compared with the model group,low-and high-dose ginsenoside Rg1 significantly decreased the expression of atrophy,fibrosis,and fatty infiltration related genes(P<0.05).There was no significant difference in paw print area,supraspinatus muscle contractility,and myofiber cross-sectional area between ginsenoside Rg1 low and high dose groups(P>0.05),and all other indexes were better in the ginsenoside Rg1 high dose group than in the ginsenoside Rg1 low dose group(P<0.05).To conclude,ginsenoside Rg1 could significantly reduce muscle atrophy,fibrosis and fatty infiltration following massive rotator cuff tear in mice,which is beneficial to improve muscle strength and limb function.

ObjectiveTo evaluate the efficacy and safety of Lianhua Qingke tablets in the treatment of acute bronchitis in children with the syndrome of phlegm-heat obstructing lung. MethodA randomized， open， parallel controlled， and multi-center clinical study was conduted. Children with acute bronchitis （syndrome of phlegm-heat obstructing lung） were randomly assigned to an observation group and a control group. The control group received routine basic treatment， and the observation group was treated with Lianhua Qingke Tablets on the basis of routine basic treatment. After 7 days of treatment， the clinical efficacy， TCM efficacy， time to symptom disappearance， time to cough disappearance， and clinical safety were compared between the two groups. ResultA total of 248 children were included （124 in the observation group and 124 in the control group）. After 7 days of treatment， the total response rate in terms of clinical efficacy in the observation group was 96.8% （120/124）， which was higher than that （90.3%， 112/124） in the control group （Z=-5.034， P<0.01）. The total response rate in terms of TCM syndrome in the observation group was 97.6% （121/124）， which was higher than that （93.5%， 116/124） in the control group （χ²=-5.326， P<0.01）. The scores of physical signs and TCM symptoms in the observation group were lower than those in the control group at the time of taking medicine for 3 days and 7 days （P<0.01）. The time to symptom disappearance and the time to cough disappearance in the observation group were shorter than those in the control group （P<0.01）. Drug-related adverse reactions occurred in neither group. ConclusionLianhua Qingke tablets demonstrate a definite effect on acute bronchitis in children with the syndrome of phlegm-heat blocking lung. The tablets can significantly shorten the course of disease and relieve cough and TCM symptoms， with high safety， which is worthy of clinical application and promotion.

Hepatic fibrosis （HF） is a pathological process of abnormal repair of liver tissue structure caused by chronic liver injury， and its pathogenesis has not been fully clarified. Related studies have shown that programmed cell death may be associated with the onset of HF， and traditional Chinese medicine （TCM） has a significant effect in regulating programmed cell death to intervene against HF. This article reviews the main mechanism of the influence of programmed cell death on HF and discusses the possible mechanism of TCM regulation of programmed cell death in improving HF， which provides new ideas for TCM prevention and treatment of HF.
