Sweat pore serves as the central regulator for ascending, descending, exiting and entering of qi movement, the circulation of essence, blood, and body fluids, and the nourishment of zang-fu organs. Its proper function depends on maintaining smooth flow and avoiding stagnation. Cough variant asthma (CVA), in traditional Chinese medicine, falls under the "wind cough" category. The dysfunction of sweat pores' opening, closing, ascending, and descending is integral to the pathogenesis of CVA. This article focused on the dynamic changes in sweat pores' dysfunction throughout the progression of CVA, categorized into three stages,i.e. loss of pivot function, blockage of sweat pores, and lack of nourishment. The treatment approach centers on "wind medicinal opening sweat pores", so for the initial stage, the focus is on activating sweat pores and dispelling wind, diffusing the lungs and rectifying qi; for the progression stage, the strategy shifts to unblocking sweat pores and dispersing wind, clearing lung stagnation and resolving obstructions; for the resolution stage, the emphasis is on nourishing sweat pores and defending against wind, strengthening the lungs and consolidating the body's foundation. This approach provides a systematic approach to the clinical diagnosis and treatment of CVA.

Computational approaches, encompassing both physics-based and machine learning (ML) methodologies, have gained substantial traction in drug repurposing efforts targeting specific therapeutic entities. The human dopamine (DA) transporter (hDAT) is the primary therapeutic target of numerous psychiatric medications. However, traditional hDAT-targeting drugs, which interact with the primary binding site, encounter significant limitations, including addictive potential and stimulant effects. In this study, we propose an integrated workflow combining virtual screening based on weighted holistic atom localization and entity shape (WHALES) descriptors with in vitro experimental validation to repurpose novel hDAT-targeting drugs. Initially, WHALES descriptors facilitated a similarity search, employing four benztropine-like atypical inhibitors known to bind hDAT's allosteric site as templates. Consequently, from a compound library of 4,921 marketed and clinically tested drugs, we identified 27 candidate atypical inhibitors. Subsequently, ADMETlab was employed to predict the pharmacokinetic and toxicological properties of these candidates, while induced-fit docking (IFD) was performed to estimate their binding affinities. Six compounds were selected for in vitro assessments of neurotransmitter reuptake inhibitory activities. Among these, three exhibited significant inhibitory potency, with half maximal inhibitory concentration (IC50) values of 0.753 μM, 0.542 μM, and 1.210 μM, respectively. Finally, molecular dynamics (MD) simulations and end-point binding free energy analyses were conducted to elucidate and confirm the inhibitory mechanisms of the repurposed drugs against hDAT in its inward-open conformation. In conclusion, our study not only identifies promising active compounds as potential atypical inhibitors for novel therapeutic drug development targeting hDAT but also validates the effectiveness of our integrated computational and experimental workflow for drug repurposing.

Objective:To introduce the method of using anal fistula endoscope to treat chronic sinus tract leakage at rectal anastomosis site.Methods:We used anal fistula endoscopy to treat a patient with chronic sinus tract leakage after radical resection of rectal cancer, mainly including the following 5 steps: (1) establishing a water injection circulation system through the anus; (2) scraping off purulent coating and mucosa on the surface of the sinus tract with the brush; (3) hemostasis and removal of necrotic tissue with electrocoagulation rods; (4) filling the sinus tract with bioprotein gel; (5) compressing the sinus tract with transanal drainage tube.Results:The patient is a 70 year old male with rectal cancer. After undergoing 3D laparoscopic assisted radical resection of rectal cancer via abdominal anterior resection (Dixon's procedure) and diverting ileostomy surgery for more than 3 months, leakage of the rectal anastomosis was found through colonoscopy and anal iodine water contrast imaging .The patient started eating and flowing juice 6 hours after surgery, got out of bed 24 hours after surgery, and was discharged 48 hours after the removal of the anal canal. Three months after surgery, colonoscopy and transanal iodine hydrography showed that the sinus repair was intact. The diverting ileostomy was reduced 4 months after surgery.Conclusion:Anal fistula endoscope is safe and feasible for the treatment of chronic sinus tract anastomotic leakage in selected patients.

Objective:This study aims to compare the antiviral treatment similarities and differences in the population covered by the 2024 version of the World Health Organization's (WHO) hepatitis B prevention and treatment guidelines and the current Chinese hepatitis B prevention and treatment guidelines, so as to explore their impact on the indications for antiviral therapy in Chinese patients with chronic hepatitis B (CHB).Methods:The information of patients with chronic hepatitis B virus infection who did not receive antiviral treatment was collected through the registration database of the China Clinical Research Platform for Hepatitis B Elimination. Descriptive statistics were conducted on the demographic, blood, biochemical, and virological levels of patients according to the treatment recommendations of the two versions of the guidelines. The Mann-Whitney U test and χ2 test were used to compare the differences and proportional distribution of the treatment populations covered by the two guidelines. The χ2 test was used to analyze the coverage rate of different antiviral treatment indications.Results:A total of 21,134 CHB patients without antiviral treatment were enrolled. 69.4% of patients met the 2024 versions of the WHO guidelines' recommendations. 85.0% of patients met the current Chinese hepatitis B prevention and treatment guidelines. The WHO guidelines for antiviral therapy indications were met in younger patients with higher levels of ALT, AST, and APRI scores, as well as greater proportion of patients with higher viral loads (P<0.001). The WHO guidelines recommended a cut-off value of APRI>0.5, which raised the proportion of patients on antiviral therapy from 6.6% to 30.9%. 45.7% of patients met the antiviral indications for HBV DNA >2000 IU/ml with abnormal transaminase (ALT>30 U/L for males and ALT>19 U/L for females). The reduced APRI diagnostic cut-off value and ALT treatment threshold had further increased the treatment coverage rate by 91.6% in patients with chronic HBV infection in line with the 2024 versions of WHO guidelines.Conclusion:The reduction of the APRI diagnostic cut-off value and the ALT treatment threshold, based on the current hepatitis B guidelines of China, will further improve the treatment coverage of CHB patients.

Glaucoma is the leading irreversible blinding eye disease worldwide,and intraocular pressure(IOP)plays a key role in the occurrence and development of glaucoma.However,the underlying IOP regulatory mechanism remains un-clear.Currently,clinical IOP-lowering drugs work either by reducing aqueous humor formation or increasing aqueous hu-mor outflow with limited reduction amplitude.Recent studies demonstrate that IOP may be regulated by autonomic nerves.To understand the distribution and regulatory mechanism of autonomic nerves in the aqueous humor outflow pathway and provide new ideas for IOP-lowering study and novel drug exploration,we review the roles of the autonomic nervous system in the formation and outflow of aqueous humor in this article.
