ObjectiveTo observe the short-term and long-term efficacy of traditional Chinese medicine （TCM） surgical operations in treating mixed hemorrhoids. MethodsA multi-center retrospective cohort study was conducted， collecting clinical data from 17，831 mixed hemorrhoid surgery patients in 8 top-tier TCM hospitals in Jiangsu Province. Standardized and structured datasets were obtained through artificial intelligence models. Patients who underwent western surgical treatment were categorized into the western surgery group （11,646 cases）， and those receiving TCM surgical operations were categorized into the TCM surgery group （6185 cases）. Propensity score matching （1∶1 matching） was used to balance baseline data between groups. The primary outcome was the one-year recurrence rate， and secondary outcomes included the main symptoms （rectal bleeding， degree of prolapse） and secondary symptoms （anal distension， anal edema， wound secretion and exudation， anal stenosis， residual skin tags， perianal itching， and anal pain） measured on days 7， 28， and 60 after discharge. ResultsAfter matching， 2194 patients were included in each group. Symptom scores showed that at 28 days after discharge， the TCM surgical group had superior improvement in rectal bleeding ［OR=5.786， 95%CI （3.092，10.827）］， degree of prolapse ［OR=4.510， 95%CI （1.649，12.333）］， and anal edema ［OR=3.188， 95%CI （1.295，7.845）］ compared to the western surgical group. At 60 days post-discharge， the TCM group still showed advantages in improving rectal bleeding ［OR=5.237， 95%CI （1.077，25.464）］ and anal pain ［OR=11.697， 95%CI （1.186，115.336）］ （P＜0.05）. Long-term follow-up showed that the one-year recurrence rate in the TCM surgery group was 1.1% （8/726）， while that in the western surgery group was 2.3% （10/444）， with no statistically significant difference between the two groups （P＞0.05）. ConclusionBased on real-world data， TCM surgical treatment for mixed hemorrhoids shows significant short-term symptom improvement， particularly in terms of hemostasis， reducing swelling， and alleviating prolapse of anal masses.

Objective To explore the risk factors associated with the occurrence of dampness syndrome based on peripheral blood multiple laboratory indicators,construct predictive model and validate it.Methods A retrospective analysis was conducted on 180 patients who visited the Preventive Treatment Center of Guangdong Provincial Hospital of Chinese Medicine from May 2022 to December 2023.They were divided into two groups according to the diagnostic criteria:the damp syndrome of TCM group(n=118)and the balanced yin-yang constitution group(n=62),with the latter serving as the"non-syndrome"control group for dampness syndrome.Serum biochemical indicators were detected by electrochemiluminescence(ECL),immune cell subsets were analyzed through flow cytometer,and routine blood parameters were assessed using an automatic hematology analyzed.Logistic regression analysis was employed to screen risk factors and develop a predictive model.The Bootstrap method was used for data resampling to draw the receiver operating characteristic(ROC)curve,calibration curve,and clinical decision curve analysis(DCA)to evaluate the predictive value,consistency,and clinical efficacy of the model.Results Compared with the balanced yin-yang constitution group,the damp syndrome of TCM group showed increased levels of insulin(INS),non-high-density lipoprotein cholesterol(non HDL-C),red blood cells(RBC)and the proportion of CD4+T cells,the proportion of triglyceride(TG)>1.70 mmol/L,total cholesterol(TC)>5.20 mmol/L,low-density lipoprotein cholesterol(LDL-C)>3.37 mmol/L,and high-density lipoprotein cholesterol(HDL-C)≤1.15 mmol/L were also significantly higher,with statistical significance(U/t/χ2=-2.900～4 626,all P＜0.05).Logistic regression analysis showed that INS,TC>5.20 mmol/L,HDL-C≤1.15 mmol/L,and the proportion of CD4+T cells were independent risk factors for the occurrence of damp syndrome of TCM(all P＜0.05).Based on the screened risk factors,a forecasting model was established and a nomogram was plotted.The model had an area under the ROC curve area under curve(AUC)of 0.747(95%CI=0.672～0.822),a Brier score of 0.184 for the calibration curve,and demonstrated clinical net benefit at threshold probabilities ranging from 0.30 to 1.00.Conclusion The forecasting model constructed based on INS,TC>5.20 mmol/L,HDL-C≤1.15 mmol/L,and CD4+T cells ratio has a high predictive value for damp syndrome of TCM.

Objective:To investigate the independent predictors of the long-term clinical outcomes in patients with branch atheromatous disease (BAD) in lenticulostriate artery (LSA) territory.Methods:Patients with LSA-BAD admitted to the Department of Neurology, Zhongnan Hospital of Wuhan University from January 1, 2016 to June 1, 2019 were enrolled retrospectively. Their demography, vascular risk factor, and baseline clinical data were collected. The National Institutes of Health Stroke Scale (NIHSS) was used to evaluate the severity of stroke. The clinical outcomes were evaluated by the modified Rankin Scale at 6 months. 0-2 was defined as good outcome, and >2 was defined as poor outcome. Multivariate logistic regression analysis was used to determine the independent influencing factors of clinical outcomes in patients with LSA-BAD. Results:A total of 81 patients with LSA-BAD were enrolled. Their age 59.20±11.75 years (range, 39-81 years), 53 were male (65.4%), and median baseline NIHSS score was 1.0 (interquartile range, 0-4.0). Forty-one patients (50.6%) received intravenous thrombolysis. At 6-month follow-up after the onset, 63 patients (77.8%) had a good outcome, and 18 (22.2%) had a poor outcome. The baseline NIHSS score of the poor outcome group was significantly higher than that of the good outcome group (6.5 [0-9.0] vs. 1.0 [0-3.0]; Z=2.395, P=0.017), while the proportion of mild stroke (61.6% vs. 98.4%; χ2=17.595, P<0.001) and patients receiving intravenous thrombolysis (38.9% vs. 54.0%; χ2=4.450, P=0.035) were significantly lower than those of the good outcome group. Multivariate logistic regression analysis showed that after adjusting for other confounding factors, venous thrombolysis was independently correlated with the good outcome (odds ratio 0.099, 95% confidence interval 0.011-0.924; P=0.042), while the high baseline NIHSS score was independently associated with the poor outcome (odds ratio 1.736, 95% confidence interval 1.262-2.388; P=0.001). Conclusion:Intravenous thrombolysis is helpful to improve the outcomes of patients with LSA-BAD, and a higher baseline NIHSS score is an independent predictor of the poor outcome.

Objective:To study the effects of hydrogen molecule on the formation of pelvic and abdominal adhesions in dogs, and to explore its possible mechanism.Methods:The Beagle pelvic and abdominal adhesion model was constructed. 15 Beagle dogs were randomly divided into 3 groups: model control group, hydrogen treatment group and blank control group. The Phillips adhesion score was used to evalute the morphological adhesion degree. The morphology of intestinal, uterus and ovarian tissues was evaluated by hematoxylin-eosin (HE) staining. The inflammation biomarkers and oxygen free radical index were detected before modeling and on the 1st, 4th, 7th and 14th day after modeling. C-reactive protein (CRP), tumor necrosis factors-α (TNF-α) and interleukin(IL)-6 content in serum were detected by enzyme-linked immunosorbent assay (ELISA) kit; hydroxylamine method was used to detect the serum superoxide dismutase (SOD); thiobarbituric acid (TBA) colorimetric method was used to measure malondialdehyde concentration.Results:The Phillips adhesion score of the model control group was significantly higher than that of the blank control group ( P<0.05). The Phillips adhesion score of the hydrogen treatment group was significantly lower than that of the model control group ( P<0.05). In the hydrogen treatment group, the thickening of serous layer on the surface of intestine, uterus and ovary and the degree of inflammatory infiltration were lower than those in the model control group.The inflammatory indexes (leukocyte count, CRP, IL-6, TNF-α) and malondialdehyde level in the model control group were higher than those in the blank control group on the first day after modeling, and the superoxide dismutase (SOD) level was lower than that in the blank control group (all P<0.05); the inflammatory indexes and malondialdehyde level in the hy-drogen treatment group were lower than those in the model control group on the first day after modeling ( P<0.05), and the SOD level was higher than that in the model control group ( P<0.05). Conclusions:Hydrogen molecule can effectively inhibit the formation of pelvic adhesion in Beagle dogs, and its possible mechanism is to neutralize oxygen free radicals and reduce inflammatory reaction.

Objective: To explore the safety and effectiveness of 3D reconstruction in thoracoscopic posterior basal segmentectomy (S10). Methods: Between March 2018 to September 2018, 14 patients underwent thoracoscopic anatomical resection of the posterior basal segment of the lung (S10). Results: Of the 14 patients, including 5 males and 9 females, age (52.2±5.3)years, size (1.1±0.6)cm, 6 left S10 and 8 right S10. The number of pathological type of microinvasive adenocarcinoma, benign nodule, and metastatic carcinoma was 12, 1, and 1 cases. The average preoperative planning time was (44.9±5.7)min, and the average operation time was (134.8±26.3)min. The blood loss was (25.5±4.1)ml, with (8.1±2.7) lymphadenectomy, no positive metastasis. The coincidence rate of 3D reconstruction and intraoperative anastomosis in the tumor location, B10, A10, and V10 were 100%(14/14), 100%(14/14), 93%(13/14) and 71%(10/14). The median duration of chest tube insertion was (2.3±2.1)day. The incidence of postoperative complications was 21%(3/14), including 7%(1/14) of air leakage, 7%(1/14) of arrhythmia, 14%(2/14) of pulmonary infection, and 14%(2/14) of operation. All the cutting edge was >2 cm. There was no perioperative death, no conversion to thoracotomy or lobectomy. The mean follow-up time was (8.1±2.2)months. There were no recurrence, metastasis or death in the 14 patients. One patient had chronic cough and no hemoptysis. Conclusions Preoperative 3D reconstruction make the anatomic thoracoscopic posterior basal segmentectomy (S10) safer and more effective.

Objective To investigate the changes of fecal short-chain fatty acids (SCFA) and bile acid levels in patients with colon cancer.Methods Totally 189 patients with colon cancer (CC group),201 patients with adenomatous polyp (AP group),and 512 healthy patients (control group) who were confirmed by endoscopy were included in this study.The fecal SCFA and bile acid levels were measured by enzyme linked immunosorbent assay.Results The total bile acids,primary bile acids,and secondary bile acids were not significantly different among these three groups (P ＞ 0.05).The chenodeoxycholate level in the CC group [0.338 (0.101,0.416) mg/g] was significandy higher than that in AP group [0.241 (0.108,0.375) mg/g] and control group [0.248 (0.110,0.371) mg/g] (P=0.025,P=0.023),but was not significantly different between the AP groupand the control group (P ＞ 0.05).The deoxycholic acid level in CC group [0.375 (0.136,0.503) mg/g] and AP group [0.369 (0.113,0.494) mg/g] were significandy higher than that in control group [0.277 (0.115,0.412) mg/g] (P=0.026,P=0.024),and the difference between CC group and AP group was not statistically significant (P ＞ 0.05).The level of lithocholic acid in CC group [0.386 (0.147,0.507) mg/g] was significantly higher than those in the AP group [0.103 (0.012,0.238) mg/g] and control group [0.239 (0.081,0.405) rng/g] (P=0.011,P=0.027); also,its level in AP group was significantly lower than that in the control group (P =0.022).The levels of total short-chain fatty acids,acetic acid,propionic acid,and isovaleric acid were not significantly different among the control group,AP group,and CC group (P＞0.05).The levels of butyrate [0.105 (0.059,0.198) mg/g,0.090 (0.050,0.183) mg/g],isobutyl acid [0.036 (0.024,0.046) mg/g,0.025 (0.020,0.034) mg/g] in CC group and AP group were significantly higher than in the control group [0.081 (0.051,0.107) mg/g,0.021 (0.016,0.029) mg/g] (butyrate:P=0.026,P=0021; isobutyl acid:P=0.025,P=0.019),and the difference between CC group and AP group was statistically significant (butyrate:P =0.031; isobutyl acid:P =0.024).Conclusions Fetal chenodeoxycholic acid,lithocholic acid,butyric acid,and isobutyric acid may play a role in the developmem of colon cancer,while deoxycholic acid may also be implicated in both colon cancer and colon adenomas.No association is found between other SCFA and bile acids and colorectal cancer/adenoma.

OBJECTIVETo investigate the role of hepatocyte apoptosis and mitochondrial permeability transition pore (MPTP) opening in the pathogenesis of nonalcoholic fatty liver disease (NAFLD).

METHODSThirty male SD rats were randomized into normal diet group and high-fat diet group. At 4, 8 and 12 week of feeding. The hepatocyte apoptosis index (AI) was measured using flow cytometry, and MPTP opening was evaluated with ultraviolet spectrophotometry. Immunohistochemistry was employed to detect hepatic expressions of Bcl-2 and Bax, and Western blotting was used to detect Bax protein expression changes.

RESULTSHigh-fat feeding resulted in significantly increased hepatocyte AI at 4-12 weeks and gradually increased MPTP opening. In the high-fat diet group, hepatic Bcl-2 expression was detected but the positive cell number remained stable, whereas Bax-positive cell number increased steadily with time with progressively increased intensity of Bax protein expression, resulting in gradually decreased Bcl-2/Bax ratio.

CONCLUSIONHepatocyte apoptosis occurs in the rat model of NAFLD in close correlation with mitochondrial damage. Increased MPTP opening as the result of increased Bax expression and aberrant Bcl-2/Bax ratio is an important mechanism of hepatocyte mitochondrial damage in NAFLD.
