ObjectiveTo investigate the mechanisms by which Bushen Tongluo Jiangzhuo prescription improves renal fibrosis in rats with chronic kidney disease （CKD） through the phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）/mammalian target of rapamycin （mTOR） signaling pathway. MethodsSeventy specific pathogen-free （SPF） Sprague-Dawley （SD） rats were randomly divided into a control group （n=15） and a modeling group （n=55）. Rats in the modeling group were administered a 2.5% adenine suspension at a dose of 200 mg·kg^-1·d^-1 by gavage for 4 weeks to establish a CKD model. Successfully modeled rats were randomly divided into a model group， an irbesartan group （20.25 mg·kg^-1·d^-1）， and Bushen Tongluo Jiangzhuo prescription low-， medium-， and high-dose groups （5.82， 11.64， and 23.28 g·kg^-1·d^-1， respectively）， with 10 rats in each group. Each group was administered an equal volume of physiological saline， the corresponding concentration of irbesartan， or Bushen Tongluo Jiangzhuo prescription by gavage for 12 weeks. Body weight and renal function indices were dynamically monitored. Serum creatinine （SCr）， blood urea nitrogen （BUN）， urine albumin-to-creatinine ratio （ACR）， 24-hour urinary total protein （24 hUTP）， aspartate aminotransferase （AST）， alanine aminotransferase （ALT）， interleukin-1β （IL-1β）， interleukin-6 （IL-6）， and tumor necrosis factor-α （TNF-α） levels were measured using an automatic biochemical analyzer. Renal histopathological changes were observed by hematoxylin-eosin （HE） and Masson staining. Immunohistochemistry （IHC） was used to detect the expression of PI3K， Akt， phosphorylated Akt （p-Akt）， and mTOR in renal tissues. Western blot was performed to assess the protein expression of PI3K， p-Akt， Akt， phosphorylated mTOR （p-mTOR）， and mTOR in renal tissues. Real-time quantitative polymerase chain reaction （Real-time PCR） was used to determine the mRNA expression levels of PI3K， Akt， and mTOR in renal tissues. ResultsCompared with the model group， rats in the irbesartan group and the low-， medium-， and high-dose Bushen Tongluo Jiangzhuo prescription groups showed significantly decreased levels of SCr， BUN， ACR， 24 hUTP， IL-1β， IL-6， and TNF-α （P<0.01）. AST levels were significantly increased （P<0.01）， while no significant difference was observed in ALT levels. Histopathological examination revealed that， compared with the model group， renal tubular epithelial cell edema and necrosis and Bowman's capsule dilation were alleviated， inflammatory cell infiltration was reduced， and interstitial and glomerular fibrosis was markedly improved in all treatment groups， with the most pronounced effect observed in the high-dose Bushen Tongluo Jiangzhuo prescription group. Real-time PCR results showed that mRNA expression levels of PI3K， Akt， and mTOR were significantly downregulated in the high-dose group （P<0.01）. IHC results demonstrated that PI3K and p-Akt expression levels in renal tissues were significantly decreased in the high-dose group （P<0.01）. Western blot analysis further confirmed that the expression levels of PI3K， p-Akt/Akt， and p-mTOR/mTOR were significantly reduced in the high-dose group （P<0.01）. ConclusionBushen Tongluo Jiangzhuo prescription improves renal function indices in CKD rats， reduces collagen deposition in renal tissues， and decreases serum inflammatory factor levels. Its protective effect on renal function may be achieved by activating autophagy through downregulation of the PI3K/Akt/mTOR signaling pathway， thereby alleviating renal fibrosis.

AIM: To analyze the pathological features, immunophenotype, and imaging findings of conjunctival lymphangiectasia(CL), and to explore the etiological mechanisms and provide a theoretical basis for clinical diagnosis and treatment. METHODS:This single-center descriptive cross-sectional study enrolled postoperative specimens from patients with CL who underwent surgical treatment in the hospital between Feb. 2023 and Sept. 2025. Routine hematoxylin and eosin(HE)staining and immunohistochemical staining(D2-40, CD31, CD34, CK)were performed. Anterior segment optical coherence tomography(AS-OCT)was used to observe the lesion morphology. The pathological results were comprehensively analyzed combined with clinical data. RESULTS: A total of postoperative specimens from 32 eyes of 32 patients with CL were enrolled, including 23 females(72%)and 9 males(28%), with a mean age of 53.03±12.47 y. All patients presented with single or multiple transparent cystic elevations beneath the bulbar conjunctiva. The postoperative pathological manifestations were characterized by dilation of conjunctival lymphatic vessels lined with a single layer of flattened endothelial cells, accompanied by edema and inflammatory infiltration in the surrounding stroma. All cases were positive for D2-40, confirming a lymphatic origin; some cases also expressed CD31 and CD34. AS-OCT revealed the lesions as unilocular or multilocular cystic spaces with low reflectivity. After complete surgical resection, the mean follow-up period was 16.2 mo with no recurrence.CONCLUSION:CL is a benign ocular surface lesion characterized by lymphatic vessel dilation. The endothelium co-expresses lymphatic and some vascular markers, suggesting that CL may belong to the spectrum of vascular malformations. AS-OCT has adjunctive diagnostic value, and surgical resection has definitive therapeutic efficacy.

Conjunctival lymphangiectasia is a low-incidence ocular surface disease that is currently rarely reported in the relevant literature. It may be related to cosmetic eyelid surgery, tumor, radiation or chemotherapy and other factors and often causes a foreign body sensation, lacrimation, eye pain, visual fatigue and other discomfort. These symptoms of constant eye irritation affect the patient's quality of life. At present, anterior segment optical coherence tomography can be used for clinical diagnosis, and the novel monoclonal antibody D2-40, as a marker of lymphatic endothelial cell dilatation, has high specificity in pathological diagnosis. Previous studies have not fully defined the pathogenesis of the disease, and treatment methods vary. Conventional treatment has resulted in varying degrees of damage to the conjunctiva in patients. In recent years, anti-vascular endothelial growth factor drugs have been reported to be effective in treating the disease with few complications. This article reviews the pathogenesis, diagnosis and treatment of this rare disease in order to gain a better understanding of conjunctival lymphangiectasia and provide more support for clinical diagnosis and treatment.

ObjectiveTo investigate the effect of the multidisciplinary team （MDT） management model in improving the prognosis of patients with cirrhotic portal hypertension. MethodsA total of 86 patients with cirrhotic portal hypertension who were admitted to Shenzhen Third People’s Hospital from May 2022 to July 2024 were enrolled， and according to whether the MDT treatment regimen was implemented， they were divided into execution group with 51 patients and non-execution group with 35 patients. Baseline clinical data were collected， and the patients were observed in terms of gastrointestinal bleeding， hepatic encephalopathy， liver cancer， and death from admission to the end of follow-up （January 2025）. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Wilcoxon rank-sum test was used for comparison of non-normally distributed continuous data between two groups； the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups. The Kaplan-Meier method was used to plot survival curves for the cumulative incidence rates of endpoint events （gastrointestinal bleeding， hepatic encephalopathy， liver cancer， and death）， and the Log-rank test was used for comparison between groups. The Cox proportional-hazards regression model analysis was used to investigate the effect of MDT management on the prognosis of patients. ResultsThere were significant differences between the execution group and the non-execution group in diameter of the portal vein （t=1.216， P=0.017） and ascites （χ²=4.515， P=0.034） at baseline. The patients were followed up for 14.6±6.2 months， and the survival curve analysis showed that there was a significant difference in the cumulative incidence rate of gastrointestinal bleeding between the two groups （χ²=4.573， P=0.024）， while there were no significant differences in the incidence rates of other outcome events between the two groups （all P>0.05）. The Cox regression analysis showed that the execution group had a reduced risk of gastrointestinal bleeding （hazard ratio=0.262， 95% confidence interval： 0.110 — 0.630， P=0.003）. ConclusionImplementation of the MDT treatment regimen can significantly reduce the short-term risk of gastrointestinal bleeding in patients with cirrhotic portal hypertension， while its long-term benefits require further follow-up verification.

ObjectiveTo explore the mechanism of Huanglian Wendantang on damp-heat type diabetes enteropathy rats based on the G protein coupled bile acid receptor 5/glucagon like peptide-1 （TGR5/GLP-1） signaling pathway and intestinal flora. MethodsA total of 72 male Sprague Dawley （SD） rats were adaptively fed for one week. Twelve SD rats were randomly selected as a blank group and fed with an ordinary diet. The rest of the SD rats were fasted for 12 hours without water. A rat model with damp-heat type diabetes enteropathy was made by left intraperitoneal injection of streptozotocin （55 mg·kg^-1） and high sugar and high fat diet （20% sucrose solution + high fat diet） in a humid and hot environment （artificial climate box： temperature 30-34 ℃， relative humidity： 85%-95%）. After successful modeling， the rats were randomly divided into a model group， a metformin group （200 mg·kg^-1）， low-dose， medium-dose， and high-dose Huanglian Wendantang groups （7.10， 14.20， 28.39 g·kg^-1）， with 12 rats in each group. The normal group and the model group were orally administered with physiological saline once a day for 6 consecutive weeks. During the observation period， the weight and blood glucose levels of rats were measured and recorded weekly. After the administration， fresh feces were collected from rats， and 16S rRNA sequencing technology was used to study the differences and changes in intestinal flora among different groups. The levels of tumor necrosis factor-α （TNF-α） and interleukin-6 （IL-6） in the serum of rats were detected by enzyme-linked immunosorbent assay （ELISA）， and the pathological morphological changes of colon tissue were examined. The expression of TGR5 and GLP-1 in colon tissue was detected by immunohistochemistry， and the expression of TGR5 and GLP-1 proteins in colon tissue was measured by Western blot. ResultsCompared with the blank group， the model group showed a decrease in body weight， an increase in blood glucose， and significant damp-heat symptoms. The levels of IL-6 and TNF-α in serum were significantly increased （P<0.01）. The expression of TGR5 and GLP-1 was decreased （P<0.01）， and the pathogenic bacteria were increased. Compared with the model group， the treatment groups exhibited improvements in body weight， blood glucose levels， and damp-heat syndrome in rats. Among them， the high-dose group of Huanglian Wendantang displayed the most significant improvement effect， with significantly reduced inflammation levels （P<0.01） and elevated expression of TGR5 and GLP-1 （P<0.01）. Colonic pathological sections showed that Huanglian Wendantang could effectively ameliorate colonic pathological changes. The 16S rRNA sequencing result indicated a significant increase in beneficial bacteria in the treatment groups. ConclusionHuanglian Wendantang can effectively ameliorate the damp-heat symptoms and blood glucose levels in rats with damp-heat type diabetes enteropathy， and it may exert an effect by regulating the TGR5/GLP-1 signaling pathway and intestinal flora disorder.

ObjectiveTo investigate the clinical efficacy and potential mechanism of Shengmai Jiuxin decoction in the treatment of acute decompensated heart failure （ADHF） with the traditional Chinese medicine （TCM） pattern of Qi and Yin deficiency， Yang deficiency， and blood stasis. MethodsA total of 68 patients diagnosed with ADHF of Qi and Yin deficiency， Yang deficiency， and blood stasis type were randomly assigned to an observation group （34 cases） and a control group （34 cases）. Both groups received conventional Western medical treatment， while the observation group was additionally administered Shengmai Jiuxin decoction. Parameters compared before and after treatment included： TCM syndrome score， TCM syndrome efficacy， New York Heart Association （NYHA） functional classification， left ventricular ejection fraction （LVEF）， N-terminal pro-B-type natriuretic peptide （NT-proBNP）， six-minute walk distance （6MWD）， hypoxia-inducible factor-1 alpha （HIF-1α）， vascular endothelial growth factor A （VEGF-A）， Caspase-3， and the number of rehospitalizations for heart failure within one month after discharge. ResultsThere were no significant differences in sex， age， vital signs， or underlying diseases between the two groups. Compared with baseline， both groups exhibited significant reductions in TCM syndrome scores， NT-proBNP， and HIF-1α levels （P<0.01）， as well as significant increases in 6MWD， LVEF， VEGF-A， and Caspase-3 levels （P<0.05， P<0.01）. After treatment， the observation group showed significantly greater reductions in TCM syndrome score， NT-proBNP， HIF-1α， and Caspase-3 levels compared with the control group （P<0.05） and significantly greater increases in 6MWD， TCM syndrome efficacy， and VEGF-A levels （P<0.05）. No significant differences were observed between the groups in NYHA functional classification， LVEF， or the number of rehospitalizations for heart failure within one month after discharge. No drug-related adverse events were reported in either group during the treatment period. ConclusionShengmai Jiuxin decoction can improve cardiac function and clinical symptoms in patients with ADHF of Qi and Yin deficiency， Yang deficiency， and blood stasis type. Its mechanisms may be related to the regulation of the HIF-1 signaling pathway by modulating targets such as HIF-1α， VEGF-A， and Caspase-3.

Objective:To compare the preoperative presentation, intraoperative findings, and postoperative outcomes between middle ear cholesteatoma with tympanosclerosis （MECwTS） and middle ear cholesteatoma without tympanosclerosis （MECw/oTS）, thereby investigating the clinical characteristics of MECwTS. Methods:A retrospective analysis was conducted on the clinical data of 120 patients with middle ear cholesteatoma. Patients were divided into two groups based on the presence or absence of concomitant tympanosclerosis: the MECwTS group （n=49） and the MECw/oTS group （n=71）. All patients underwent preoperative evaluations including temporal bone CT, otoscopic examination, pure-tone audiometry, tympanometry, and assessment using the Zurich Chronic Middle Ear Inventory （ZCMEI-21） quality of life scale. All patients underwent canal wall down mastoidectomy with tympanoplasty. Concurrent ossicular chain reconstruction was performed: partial ossicular replacement prosthesis （PORP） in 83 cases and total ossicular replacement prosthesis （TORP） in 37 cases. Intraoperative disease severity was assessed using the Cholesteatoma Comprehensive Score Scale （CCSS）. Postoperative follow-up lasted at least one year and included pure-tone audiometry, otoscopic examination, and the ZCMEI-21 scale administered at ≥1 year post-surgery. Preoperative and postoperative air-bone gap （ABG） and ZCMEI-21 scores were compared between the MECwTS and MECw/oTS groups. Additionally, surgical efficacy was defined as a postoperative ABG ≤20 dB; the hearing improvement efficacy of PORP versus TORP was compared based on this criterion. Results: ①Preoperative ABG showed no significant difference between the MECw/oTS and MECwTS groups（P>0.05）. Postoperative ABG was （18.65±10.21） dB in the MECw/oTS group versus （22.55±9.53） dB in the MECwTS group, demonstrating a statistically significant intergroup difference （P<0.05）. ②Intraoperative CCSS scores were significantly higher in the MECwTS group （8.04±2.18） compared to the MECw/oTS group （5.93±1.44） （P<0.05）. ③Preoperative ZCMEI-21 scores showed no significant difference between groups （P>0.05）. Postoperative ZCMEI-21 scores were （22.24±8.11） in the MECw/oTS group versus （27.02±7.21） in the MECwTS group, indicating a statistically significant difference （P<0.05）. ④Postoperative ABG ≤20 dB was achieved in 54 patients （65.06%, 54/83） in the PORP group and 16 patients （43.24%, 16/37） in the TORP group. This difference in efficacy rates was statistically significant （P<0.05）. The overall efficacy rate for ossiculoplasty was 58.33% （70/120）. Conclusion: Patients with MECwTS exhibit more severe middle ear and mastoid pathology compared to those with MECw/oTS, resulting in poorer postoperative hearing levels and quality of life outcomes. Both PORP and TORP implantation can improve postoperative hearing to some extent; however, PORP appears to offer superior hearing improvement efficacy compared to TORP.

Objective:To observe the effect of combining heat-sensitive moxibustion with action observation therapy in the treatment of spastic wrist and hand dysfunction post-stroke.Methods:Ninety stroke survivors with spasmodic wrist and hand dysfunction were randomly assigned to a heat-sensitive moxibustion group, an action observation group, or a combination group, each of 30. In addition to routine rehabilitation treatment, the groups received heat-sensitive moxibustion, action observation therapy or moxibustion followed by action observation therapy in 6 sessions a week over 6 weeks. Surface electromyography signals (iEMG and RMS) were recorded from the affected wrist and hand muscles before and after the treatment. All of the participants were also assessed using the Fugl-Meyer motor assessment for the upper extremities (FMA-UE).Results:After treatment, a significant improvement was observed in the average FMA-UE values, with that of the combination group (17.2±2.1) significantly higher than those of the other two groups. The average iEMG of the wrist flexors and extensors, the extensors of the fingers, and abductor pollicis brevis had increased significantly, with the combination group′s averages significantly higher than those of the other two groups. The average RMS values of those muscles had decreased significantly after the treatment, with those of the combination group significantly lower than the others.Conclusions:Combining heat-sensitive moxibustion and action observation therapy can significantly reduce muscle tension, and promote strength and better functioning of spastic wrist and hand muscles after a stroke. The combination is worthy of clinical application and promotion.
