AIM:To analyze the influencing factors of visual outcome after vitrectomy for polypoidal choroidal vasculopathy(PCV)combined with vitreous hemorrhage and establish a predictive model.METHODS: A retrospective analysis was conducted on the clinical data of 129 cases(129 eyes)of patients who underwent vitrectomy for PCV combined with vitreous hemorrhage from June 2021 to January 2024 in our hospital. They were divided into elevated group(71 eyes)and non-elevated group(58 eyes)according to visual outcome at early posoperative stage(within 24 mo). Another 30 cases(30 eyes)of PCV with vitreous hemorrhage undergoing vitrectomy were selected as external validation data. The predictive value of the model for the postoperative visual outcomes of both internal and external populations was evaluated.RESULTS: The non-elevated group had a higher proportion of patients aged ≥60 years, diabetes, continuous abnormalities of the ellipsoid zone(EZ)during surgery, bleeding involving the macular fovea, and postoperative retinal scar formation than the elevated group were independent factors affecting postoperative visual acuity(all P<0.05). The AUC of the predictive model for predicting the postoperative visual outcomes of internal and external populations was 0.824(95%CI: 0.750-0.898)and 0.809(95%CI: 0.723-0.865), respectively.CONCLUSION:Patients aged ≥60 years, diabetes, intraoperative continuous abnormalities of EZ, bleeding involving the macular fovea, and postoperative retinal scar formation are influencing factors for visual outcome after vitrectomy in patients with PCV combined with vitreous hemorrhage. A predictive model based on those factors has been established, which has a certain predictive value for postoperative visual outcome.

Objective This study aims to explore the research hotspots and trends of Polygoni Multiflori Radix(processed)and provide a reference for follow-up research by bibliometric visualization analysis.Methods Relevant Polygoni Multiflori Radix literatures were collected through databases such as PubMed,Web of Science and China National Knowledge Infrastructure.Use CiteSpace 6.1.R6 software to do bibliometric analysis on the number and years of articles,research fields,countries/regions,institutions,authors,keywords,co-citation references,and build visual maps.Results A total of 1 517 literatures(1 131 Chinese literatures and 386 English literatures)were searched through databases in this review.We therefore conducted a quantitative analysis of accessible literature published over the last 30 years found that a very modest upward trend in publication volume from Chinese and a notable increase in publication over the world.Among the author teams,there was some cooperation,and the author team with the most published papers cooperated more closely,such as XIAO Xiao-he and WANG Jia-bo's team.In particular reducing toxicity and increasing efficiency by processing,and the toxicity and the rationalusage of Polygoni Multiflori Radix were a main research direction for nearly ten years.Meanwhile,through the co-occurrence analysis of keywords,we constructed and visualized a keyword network to explore the hotspots and future directions of Polygoni Multiflori Radix.We clearly found that effective and toxic homologous components,molecular mechanisms and early warning surveillance of hepatotoxicity might be the next topics for Polygoni Multiflori Radix.Conclusion The research on the homologous chemical components of Polygoni Multiflori Radix(processed)has been very active.The research on the conversion relationship and mechanism of homologous components of Polygoni Multiflori Radix(processed)and the mechanism of hepatotoxicity will be the research focus and development trend in this field.

Objective To investigate the effect of early postoperative abnormal blood glucose on the short-term prognosis of non-small cell lung cancer(NSCLC),and to analyze the clinical characteristics and risk factors related to poor early prognosis.Methods A total of 897 patients with NSCLC who underwent thoracoscopic surgery in Huadong Hospital,Fudan University from Jan 2020 to Aug 2021 were divided into hyperglycemia(HG)group(>7.8 mmol/L)and normal blood glucose(NG)group(≤7.8 mmol/L and≥3.9 mmol/L)according to the early postoperative blood glucose values.Additionally,the patients were divided into higher blood glucose fluctuation group(≥4 mmol/L)and the group with lower blood glucose fluctuation(<4 mmol/L)basing on the fasting blood glucose.Using Logistic regression models,column line charts,ROC curves and other methods,we aimed to clarify the impact of early postoperative blood glucose abnormalities on short-term prognosis,explore clinical characteristics associated with poor short-term outcomes,identify other high-risk factors,and establish relevant risk prediction models.Results Compared with the NG group,the incidence of postoperative pneumonia,thromboembolism,ICU admission rate,total length of hospital stay and hospital cost were significantly higher in the HG group(P<0.05).Higher blood glucose fluctuation group had a greater risk of ICU admission(P=0.003).Logistic regression analysis showed that age,preoperative fasting glucose,white blood cell count and cytokeratin 19 fragment antigen 21-1(CYFRA21-1)were risk factors for postoperative hyperglycemia(P<0.05).Contrary to the effect of BMI,diabetes,male patients,higher blood glucose fluctuation,white blood cell count and age were the risk factors for postoperative adverse events(P<0.05).The AUC of the column line chart model was 0.661(95%CI:0.624-0.698),indicating good discriminative ability for predicting poor short-term prognosis postoperatively.Calibration curves also demonstrated good consistency between predicted and actual probabilities.Conclusion Early postoperative blood glucose fluctuations independently impact the short-term prognosis of thoracoscopic NSCLC patients.Blood glucose combined with gender,BMI,white blood cell count,age and diabetes history can serve as predictive factors for poor short-term prognosis postoperatively.Additionally,a column line chart constructed based on these factors may aid clinicians in early intervention for NSCLC patients with indications.

Objective:To explore the role of mechanical hemodynamic support (MHS) in mapping and catheter ablation of patients with hemodynamically unstable ventricular tachycardia (VT), report single-center experience in a cohort of consecutive patients receiving VT ablation during MHS therapy, and provide evidence-based medical evidence for clinical practice.Methods:This was a retrospective cohort study. Patients with hemodynamically unstable VT who underwent catheter ablation with MHS at Beijing Anzhen Hospital, Capital Medical University between August 2021 and December 2023 were included. Patients were divided into rescue group and preventive group according to the purpose of treatment. Their demographic data, periprocedural details, and clinical outcomes were collected and analyzed.Results:A total of 15 patients with hemodynamically unstable VT were included (8 patients in the rescue group and 7 patients in the preventive group). The acute procedure was successful in all patients. One patient in the rescue group had surgical left ventricular assist device (LVAD) implantation, remaining 14 patients received extracorporeal membrane oxygenation (ECMO) for circulation support. ECMO decannulation was performed in 12 patients due to clinical and hemodynamic stability, of which 6 patients were decannulation immediately after surgery and the remaining patients were decannulation at 2.0 (2.5) d after surgery. Two patients in the rescue group died during the index admission due to refractory heart failure and cerebral hemorrhage. During a median follow-up of 30 d (1 d to 12 months), one patient with LVAD had one episode of ventricular fibrillation at 6 months after discharge, and no further episodes of ventricular fibrillation and/or VT occurred after treatment with antiarrhythmic drugs. No malignant ventricular arrhythmia occurred in the remaining 12 patients who were followed up.Conclusions:MHS contributes to the successful completion of mapping and catheter ablation in patients with hemodynamically unstable VT, providing desirable hemodynamic status for emergency and elective conditions.

Objective:To investigate the risk factors for high-output stoma (HOS) in patients undergoing rectal cancer radical resection combined with terminal ileostomy.Methods:A retrospective analysis was conducted on the medical records of 104 patients who underwent radical resection for rectal cancer combined with terminal ileostomy at Northern Jiangsu People′s Hospital from January 2020 to December 2022. Among them, 77 were male and 27 were female, with ages ranging from 31 to 84 years and an average age of 62.60 years. HOS was defined as an average stoma output ≥1500 mL/24 h within 3 days after resuming oral intake. Based on the presence of HOS post-surgery, patients were divided into the HOS group ( n=29) and the non-HOS group ( n=77). The two groups were compared based on gender, age, body mass index (BMI), preoperative albumin, hemoglobin, fasting blood glucose, surgery duration, surgical approach, intraoperative blood loss, postoperative albumin, hemoglobin, white blood cell count, and C-reactive protein (CRP). Data were analyzed using SPSS27.0. Continuous data were expressed as mean±standard deviation( ± s), and independent t-tests or non-parametric tests were used for group comparisons. Chi-square tests were used for categorical data, and logistic regression was employed to evaluate the influence of various factors on the occurrence of HOS. Results:There were no statistically significant differences between the two groups in terms of gender, preoperative albumin, hemoglobin, fasting blood glucose, surgery duration, surgical approach, intraoperative blood loss, postoperative albumin, hemoglobin, or white blood cell count ( P>0.05). Univariate logistic regression analysis indicated that older patients were more likely to develop HOS ( P=0.037, OR=1.047), those with lower BMI were at higher risk of HOS ( P<0.001, OR=0.448), and elevated postoperative CRP was associated with an increased likelihood of HOS ( P<0.001, OR=1.027). Multivariate logistic regression analysis showed that BMI ( OR=0.302, 95% CI: 0.164-0.555, P<0.001) and postoperative CRP ( OR=1.045, 95% CI: 1.023-1.068, P<0.001) were independent risk factors for the occurrence of HOS. Conclusion:Lower BMI and elevated postoperative CRP are significant independent risk factors for the development of HOS in rectal cancer patients.

Objective To investigate the effect of Xiao Chaihu Decoction and Xiangsha Liujunzi Decoction on the changes of gastric mucosal pathological score and gastrointestinal hormones in patients with chronic atrophic gastritis(CAG)of liver stagnation and spleen deficiency type.Methods A total of 156 cases of CAG patients with liver stagnation and spleen deficiency syndrome were randomly divided into a control group and an observation group,78 cases in each group.The control group was treated with conventional western medicine,and the observation group was treated with Xiao Chaihu Decoction and Xiangsha Liujunzi Decoction on the basis of treatment for the control group.The course of treatment covered four weeks.The changes in the scores of traditional Chinese medicine(TCM)symptoms such as epigastric distention and pain,poor appetite,loose stools,limb weakness,belching and acid regurgitation,gastric mucosal pathological scores and serum levels of gastrointestinal hormones of motilin(MTL)and gastrin(GAS)in the two groups were observed before and after treatment.The negative conversion rate of Helicobacter pylori(Hp)in the two groups was compared,and the clinical efficacy and safety of the two groups were evaluated.Results(1)After four weeks of treatment,the total effective rate of the observation group was 93.59％(73/78),which was significantly higher than 82.05％(64/78)of the control group,and the difference between the two groups was statistically significant(P＜0.05).(2)After treatment,the scores of TCM symptoms such as epigastric distention and pain,poor appetite,loose stool,limb weakness,belching and acid regurgitation in the two groups were significantly decreased compared with those before treatment(P＜0.05),and the decrease in the observation group was significantly superior to that in the control group(P＜0.05).(3)After treatment,the pathological scores of gastric mucosa in the two groups were significantly decreased when compared with those before treatment(P＜0.05),and the decrease in the observation group was more significant than that in the control group(P＜0.01).(4)After four weeks of treatment,the negative conversion rate of Hp in the observation group was 91.03％(71/78),which was significantly higher than that in the control group(75.64％,59/78),and the difference between the two groups was statistically significant(P＜0.05).(5)After treatment,the level of serum GAS in the two groups was significantly decreased(P＜0.05)and the serum MTL level was significantly increased compared with that before treatment(P＜0.05);the decrease of serum GAS level and the increase of serum MTL level in the observation group were significantly superior to those in the control group(P＜0.05).(6)There were no obvious abnormalities in the routine test of blood,urine,stool,kidney function,and liver function,electrocardiograph and other safety indicators during the treatment of the two groups of patients,no adverse reactions such as dizziness,rash and chest distress occurred either,with high safety.Conclusion Xiao Chaihu Decoction combined with Xiangsha Liujunzi Decoction exerts a significant therapeutic effect on GAS of liver stagnation and spleen deficiency type,which can effectively relieve the clinical symptoms,improve the pathological changes of gastric mucosa and promote Hp negative conversion.The therapeutic mechanism may be related to the regulation of gastrointestinal hormone levels.
