ObjectiveTo analyze the distribution characteristics of traditional Chinese medicine （TCM） syndrome elements in different risk populations of heart failure complicated with type 2 diabetes. MethodsClinical data of 675 type 2 diabetes patients were retrospectively collected. Lasso-multivariate Logistic regression was used to construct a clinical prediction nomogram model. Based on this， 441 non-heart failure patients were divided into a low-risk group （325 cases） and a high-risk group （116 cases） according to the median risk score of heart failure complicated with type 2 diabetes. TCM diagnostic information （four diagnostic methods） was collected for both groups， and factor analysis was applied to summarize the distribution of TCM syndrome elements in different risk populations. ResultsLasso-multivariate Logistic regression analysis identified age， disease duration， coronary heart disease， old myocardial infarction， arrhythmia， absolute neutrophil count， activated partial thromboplastin time， and α-hydroxybutyrate dehydrogenase as independent risk factors for heart failure complicated with type 2 diabetes. These were used as final predictive factors to construct the nomogram model. Model validation results showed that the area under the curve （AUC） of the receiver operating characteristic （ROC） curve for the modeling group and validation group were 0.934 and 0.935， respectively. The Hosmer-Lemeshow test （modeling group P = 0.996， validation group P = 0.121） indicated good model discrimination. Decision curve analysis showed that the curves for All and None crossed in the upper right corner， indicating high clinical utility. The low-risk and high-risk groups each obtained 14 common factors. Preliminary analysis revealed that the main disease elements in the low-risk group were qi deficiency （175 cases， 53.85%）， dampness （118 cases， 36.31%）， and heat （118 cases， 36.31%）， with the primary locations in the spleen （125 cases， 38.46%） and lungs （99 cases， 30.46%）. In the high-risk group， the main disease elements were yang deficiency （73 cases， 62.93%）， blood stasis （68 cases， 58.62%）， and heat （49 cases， 42.24%）， with the primary locations in the kidney （84 cases， 72.41%） and heart （70 cases， 60.34%）. ConclusionThe overall disease characteristics in different risk populations of type 2 diabetes patients with heart failure are a combination of deficiency and excess， with deficiency being predominant. Deficiency and heat are present throughout. The low-risk population mainly shows qi deficiency with dampness and heat， related to the spleen and lungs. The high-risk population shows yang deficiency with blood stasis and heat， related to the kidneys and heart.

Objective:To compare the postoperative recurrence rates between Thulium laser en bloc resection of bladder tumor (ERBT) and traditional transurethral resection of bladder tumor (TURBT) in treating patients with non-muscle invasive bladder cancer (NMIBC).Methods:A retrospective analysis was conducted on the clinical data of 1 439 patients with NMIBC who underwent either Thulium laser ERBT or TURBT in Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, between January 2010 and March 2024. Among them, 201 patients received Thulium laser ERBT, while 1 238 patients underwent TURBT. Propensity score matching (PSM) was employed in a 1∶1 ratio to eliminate selection bias due to non-random assignment, ensuring the comparability of clinical baseline data such as gender, age, pathological diagnosis, T stage, tumor grade, tumor size, and tumor number between the two groups. Kaplan-Meier method was used to generate recurrence-free survival curves for the matched groups, and the log-rank test was conducted to compare differences between the groups. Univariate and multivariate Cox regression analyses were performed to identify independent risk factors affecting postoperative recurrence.Results:After PSM matching, 193 patients were included in each group. There were no statistically significant differences between the two groups in terms of gender ( P=0.317), age ( P=0.207), pathological type ( P=0.756), T stage ( P=0.402), tumor grade ( P=0.965), tumor size ( P=0.821), or number of tumors ( P=0.421). The median follow-up time was 16.2(8.0, 33.9) months. Excluding patients with non-urothelial tumors such as adenocarcinoma and squamous cell carcinoma, there were 180 cases in the Thulium laser ERBT group and 184 cases in the TURBT group. Survival analysis showed that the postoperative recurrence rate of urothelial carcinoma patients in the Thulium laser ERBT group was lower than that in the TURBT group [20.0%(36/180) vs. 38.6%(71/184), P<0.001]. Stratified survival analysis indicated that in patients with tumor diameters ≤30 mm [22.3%(29/130) vs. 33.6%(45/134), P=0.017] or >30 mm [14.0%(7/50) vs. 52.0%(26/50), P=0.002], the Thulium laser ERBT group had lower postoperative recurrence rate compared to the TURBT group.Among patients with single tumor, the recurrence rate in the Thulium laser ERBT group was lower than in the TURBT group[10.5%(11/105) vs. 31.5%(35/111), P<0.001]. However, among patients with multiple tumors, there was no statistically significant difference in recurrence rates between the Thulium laser ERBT group and the TURBT group [35.7%(25/70) vs. 47.9%(34/71), P=0.061]. Univariate and multivariate Cox regression analyses indicated that Thulium laser ERBT treatment was an independent protective factor against postoperative recurrence in NMIBC patients ( HR=0.44, 95% CI 0.30-0.66, P<0.001). Patients with adenocarcinoma ( HR=5.85, 95% CI 2.07-16.51, P<0.001), squamous cell carcinoma ( HR=2.98, 95% CI 1.04-8.55, P=0.042), or other types of tumors ( HR=2.98, 95% CI 1.14-7.75, P=0.026) had higher risks of recurrence. High-grade tumor patients faced increased risks of postoperative recurrence ( HR=1.84, 95% CI 1.21-2.79, P=0.004). Additionally, tumors >30 mm had increased risks of postoperative recurrence compared to those ≤30 mm ( HR=2.00, 95% CI1.31-3.05, P=0.001). Patients with single tumor had significantly reduced risks of postoperative recurrence compared to those with multiple tumors ( HR=0.50, 95% CI 0.34-0.73, P<0.001). Conclusions:Regardless of tumor diameter (≤30 mm or >30 mm), Thulium laser ERBT significantly reduces the postoperative recurrence rate in patients with urothelial carcinoma compared to TURBT, with the advantage being more pronounced in patients with single bladder tumor. Additionally, patients with high-grade tumors, tumor diameters >30 mm, or multiple bladder tumors have higher risk of postoperative recurrence.

Objective:To investigate the influence of curative-intent resection with textbook outcomes of liver surgery (TOLS) on long-term prognosis of gallbladder carcinoma (GBC).Methods:The retrospective cohort study was conducted. The clinicopathological data of 824 patients with GBC in the national multicenter database of Biliary Surgery Group of Elite Group of Chinese Journal of Digestive Surgery, who were admitted to 15 medical centers from January 2014 to January 2021, were collected. There were 285 males and 539 females, aged (62±11)years. According to the evalua-tion criteria of TOLS, patients were divided into those who achieved TOLS and those who did not achieve TOLS. Measurement data with normal distribution were represented as Mean± SD, and com-parison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test. Comparison of ordinal data were conduc-ted using the Mann-Whitney U test. The Kaplan-Meier method was used to calculate survival rate and draw survival curve, and the Log-rank test was used for survival analysis. The COX stepwise regression model with backward Wald method was used for univariate and multivariate analyses. Results:(1) Achievement of TOLS. Of the 824 patients undergoing curative-intent resection for GBC, there were 510 cases achieving TOLS and 314 cases not achieving TOLS. (2) Follow-up. Of the 824 patients undergoing curative-intent resection for GBC, after excluding 112 deaths within 90 days after discharge, 712 cases were included for the survival analysis. The median follow-up time, median overall survival time and 5-year overall survival rate of the 510 patients achieving TOLS were 22.1(11.4,30.1)months, 47.6(30.6,64.6)months and 47.5%. The median follow-up time, median overall survival time and 5-year overall survival rate of the 202 patients not achieving TOLS were 14.0(6.8,25.5)months, 24.3(20.0,28.6)months and 21.0%. There was a significant difference in overall survival between patients achieving TOLS and patients not achieving TOLS ( χ2=58.491, P<0.05). (3) Analysis of factors influencing prognosis of patients. Results of multivariate analysis showed that TOLS, carcinoembryonic antigen (CEA), CA19-9, poorly differentiation of tumor, T2 stage of eighth edition of American Joint Committee on Cancer (AJCC) staging, T3 and T4 stage of eighth edition of AJCC staging, N1 stage of the eighth edition of AJCC staging, N2 stage of the eighth edition of AJCC staging, adjuvant therapy were independent factors influencing overall survival time of patients undergoing curative-intent resection for GBC ( hazard ratio=0.452, 1.479, 1.373, 1.612, 1.455, 1.481, 1.835, 1.978, 0.538, 95% c onfidence interval as 0.352-0.581, 1.141-1.964, 1.052-1.791, 1.259-2.063, 1.102-1.920, 1.022-2.147, 1.380-2.441, 1.342-2.915, 0.382-0.758, P<0.05). Conclusion:Patients under-going curative-intent resection for GBC with TOLS can achieve better long-term prognosis.

Diabetic macular edema(DME)is the most common complication of diabetic retinopathy,which can cause vision loss in patients.The nosogenesis of DME is complicated,and about 1/3 DME patients have poor response to anti-vascular endothelial growth factor therapy,which is defined as refractory DME.The early identification of the risk factors of refractory DME is crucial and helpful for doctors to predict the prognosis of DME and guide clinical treatment.This arti-cle reviews the risk factors of refractory DME.

AIM:To explore the effects of moderate-altitude exposure on intestinal flora in healthy individuals.METHODS:The aid-Tibet cadres,who were sent to work from Guangdong(average altitude<50 m)to Nyingchi(average altitude of 2 900 m),were recruited.A total of 76 samples were collected,including 42 samples from healthy adults with plateau living for 0 day and 34 samples from healthy adults with plateau living for 6 months.Fecal samples DNA were ex-tracted,sequenced by the 16S rDNA high-throughput sequencing technology and analyzed bioinformatically.RESULTS:Compared with the base group,α diversity was increased(P=4.00×10-4)and β diversity was decreased(P=1.00×10-3).After moderate altitude exposure,the relative abundance of phylum Proteobacteria(|LDA|>4,P<0.05),genus Escherich-ia-Shigella,species Enterococcus_faecalis,Haemophilus_influenzae and Helicobacter_sp._UNSW1.7sp decreased(adjust-ed P<0.05),wheras the relative abundance of phylum Bacteroidetes(|LDA|>4,P<0.05),genus Butyricimona,species Lactobacillus_sp._RA2113(s)and Butyricimonas_sp._Marseille-P2440(s)increased(adjusted P<0.05).The function-al prediction by PICRUSt showed a decrease in the relative abundance of pathway related to xenobiotics biodegradation and metabolism,membrane transport and amino acid metabolism(adjusted P<0.05).Conversely,the relative abundance of pathway related to biosynthesis of other secondary metabolites and nucleotide metabolism was increased(adjusted P<0.05).Finally,the results of microbiome phenotype prediction by BugBase showed that moderate altitude exposure im-proves the gut microbiota functions involving anaerobic oxygen tolerance and gram positive(adjusted P<0.05).And bacte-ria containing facultatively anaerobic oxygen tolerance,oxidative stress tolerance,gram negative and biofilm formation in the six-group decreased significantly compared with those in base group(adjusted P<0.05).CONCLUSION:Moderate altitude exposure impacts the diversity,abundance and function of intestinal flora in healthy population,suggesting that al-titude factors may have some influence on gut microbiota.

Guided by the concept of "blood-pulse-heart-spirit"， it is believed that stable angina combined with insomnia is caused by disturbance of blood vessels， which leads to loss of nourishment for the heart body and heart spirit， so the core treatment principle is to regulate the blood vessels and calm the mind. At the beginning of the disease， it shows as the liver fails to govern the free flow of qi， and disorders qi and blood； during the progress of the disease， it shows as spleen deficiency and phlegm stagnation， phlegm and blood stasis obstructing the vessels； the central mechanism of the disease shows as disturbance of blood vessels and insufficient heart yin. For the pattern of liver depression and blood stasis， pattern of phlegm and blood stasis blocking the vessels， and pattern of heart yin deficiency， it is recommended to treat by Wuzang Shenning Formula （五脏神宁方） to dredge the liver and regulate the vessels， Banxia Houpo Decoction （半夏厚朴汤） plus Gualou Xiebai Banxia Decoction （瓜蒌薤白半夏汤） to dissolve phlegm and regulate the vessels， and Yunpi Tiaoxin Decoction （运脾调心汤） to nourish the yin and regulate the vessels. Throughout the treatment， pattern differentiation and treatment is accompanied by the method of calming the mind with heavy sedatives and nourishing the blood to calm the mind， so as to achieve the purpose of regulating mind and heart together and treating the body and spirit at the same time.

Objective:To observe the efficacy and safety of subretinal injection of Aflibercept for the treatment of refractory or recurrent polypoidal choroidal vasculopathy (PCV).Methods:A prospective clinical research. From January to June 2022, 18 patients of 18 eyes with PCV diagnosed in The Affiliated Eye Hospital of Nanchang University were included in the study. All patients underwent best corrected visual acuity (BCVA), indocyanine green angiography and optical coherence tomography (OCT). The BCVA examination was performed using the international standard visual acuity chart, which was converted to logarithm of the minimum angle of resolution (logMAR) visual acuity during statistics. The large choroidal vessel thickness (LVCT), central retinal thickness (CRT), sub-foveal choroidal thickness (SFCT) and retinal pigment epithelium detachment (PED) height were measured by enhanced depth imaging technique of OCT. The choroidal vascular index (CVI) was calculated. There were 18 patients of 18 eyes, 11 males of 11 eyes and 7 females of 7 eyes. The age was (64.22±3.86) years old. The disease duration was (5.22±1.80) years. The patient had received intravitreal injection of anti-vascular endothelial growth factor (VEGF) drugs for (7.72±1.36) times. The logMAR BCVA of the affected eyes was 1.28±0.25. The SFCT, CRT, LVCT, PED height were (436.56±9.80), (432.44±44.29), (283.78±27.10), (342.44±50.18) μm, respectively, and CVI was 0.65±0.01. All eyes were treated with a single subretinal injection of 40 mg/ml Aflibercept 0.05 ml (including Aflibercept 2.0 mg). According to the results of OCT and BCVA after treatment, the lesions were divided into active type and static type. The active lesions were treated with intravitreal injection of Aflibercept at the same dose as before. Quiescent lesions were followed up. Examinations were performed 1-3, 6, 9 and 12 months after treatment using the same equipment and methods before treatment. The BCVA, LVCT, CRT, SFCT, PED height, CVI, interretinal or subretinal fluid, lesion regression rate, injection times, and complications during and after treatment were observed. The BCVA, SFCT, CRT, LVCT, PED height and CVI before and after treatment were compared by repeated measures analysis of variance.Results:Eighteen eyes received subretinal and/or intravitreal injection of Aflibercept (1.61±0.85) times (1-4 times). At the last follow-up, the polypoid lesions regressed in 4 eyes and PED disappeared in 1 eye. Compared with before treatment, BCVA ( F=50.298) gradually increased, CRT ( F=25.220), PED height ( F=144.16), SFCT ( F=69.77), LVCT ( F=136.69), CVI ( F=72.70) gradually decreased after treatment. The differences were statistically significant ( P<0.001). Macular hole occurred in 1 eye after treatment, and the hole closed spontaneously 3 months after treatment. No serious complications such as retinal tear, retinal detachment, endophthalmitis and vitreous hemorrhage occurred during and after treatment. Conclusion:Subretinal injection of Aflibercept is safe and effective in the treatment of refractory PCV.

Objective:To observe the efficacy and safety of vitrectomy combined with subretinal injection of alteplase (tPA) and intravitreal injection of Conbercept in the treatment of large area submacular hemorrhage (SMH) secondary to polypoidal choroidal vasculopathy (PCV).Methods:A retrospective clinical study. From January to September 2021, 32 eyes of 32 patients with massive SMH secondary to PCV diagnosed in the Affiliated Eye Hospital of Nanchang University were included in the study. Large SMH was defined as hemorrhage diameter ≥4 optic disc diameter (DD). There were 32 patients (32 eyes), 20 males and 12 females. The mean age was (72.36±8.62) years. All patients had unilateral disease.The duration from onset of symptoms to treatment was (7.21±3.36) days. All patients underwent best corrected visual acuity (BCVA) and optical coherence tomography (OCT) examination. BCVA examination was performed using the international standard visual acuity chart, which was converted to the logarithm of the minimum angle of resolution (logMAR) visual acuity during statistics. The central macular thickness (CMT) was measured by spectral domain-OCT. The average size of SMH was (6.82±1.53) DD. The logMAR BCVA 1.73±0.44; CMT was (727.96±236.40) μm. All patients were treated with 23G pars plana vitrectomy combined with subretinal injection of tPA and intravitreal injection of Conbercept. At 1, 3, 6 and 12 months after treatment, the same equipment and methods were used for relevant examinations before treatment. The changes of BCVA and CMT, the clearance rate of macular hemorrhage, and the complications during and after surgery were observed. BCVA and CMT before and after treatment were compared by repeated measures analysis of variance.Results:Compared with before treatment, BCVA gradually increased at 1, 3, 6 and 12 months after treatment, and the differences were statistically significant ( F=77.402, P<0.001). There was no significant difference in BCVA between any two groups at different time points after treatment ( P>0.05). Correlation analysis showed that BCVA at 12 months after treatment was negatively correlated with the course of disease ( r=-0.053, P=0.774). One week after treatment, macular hemorrhage was completely cleared in 30 eyes (93.75%, 30/32). The CMT was (458.56±246.21), (356.18±261.46), (345.82±212.38) and (334.64±165.54) μm at 1, 3, 6 and 12 months after treatment, respectively. Compared with before treatment, CMT decreased gradually after treatment, and the difference was statistically significant ( F=112.480, P<0.001). There were statistically significant differences in different follow-up time before and after treatment ( P<0.001). The number of treatments combined with Conbercept during and after surgery was (4.2±1.8) times. At the last follow-up, there was no recurrence of SMH, retinal interlamellar effusion and other complications. Conclusion:Subretinal injection of tPA combined with intravitreal injection of Conbercept is safe and effective in the treatment of large SMH secondary to PCV, and it can significantly improve the visual acuity of patients.

The clinical manifestations included wheezing, cough, fever and wheezing rale in the lungs. Diagnosis was ultimately confirmed through pathogens targeted next generation sequencing and pathological examination of respiratory coughs. Following comprehensive treatment that included antifungal therapy, the patient was cured and discharged with a good prognosis.

Objective:To investigate the effect of long-term oral aspirin on the changes in the aneurysm sac and persistent type Ⅱ endoleak after endovascular aortic repair (EVAR) of infrarenal abdominal aortic aneurysms based on propensity score-matched analysis.Methods:A retrospective cohort study was used to analyze the clinical data of 133 patients with infrarenal abdominal aortic aneurysms treated with EVAR from January 2019 to December 2021 in the Department of Vascular Surgery, Nanjing Drum Tower Hospital. There were 113 males and 20 females, aged (74.8±7.2) years (range: 59 to 95 years). Patients were divided into the group receiving aspirin ( n=80) and the group not taking aspirin ( n=53) based on whether they took aspirin regularly for a long time after surgery. The two groups were matched in a 1∶1 ratio using propensity score matching and the caliper value was 0.05. Cumulative probability curve was plotted using the Kaplan-Meier method and the Log-rank test was used to compare the differences in primary endpoint events (enlargement of the aneurysm sac, occurrence of persistent type Ⅱ endoleak) and secondary endpoint events (adverse cardiovascular events and clinically relevant bleeding events) between the two groups. Results:The follow-up time was (38.4±11.8) months (range: 30 to 58 months). Among the 133 patients, a total of 25 cases (18.8%) suffered enlargement of the aneurysm sac, including 20 cases in the group receiving aspirin and 5 cases in the group not taking aspirin; 35 cases (26.3%) suffered persistent type Ⅱ endoleak, including 26 cases in the group receiving aspirin and 9 cases in the group not taking aspirin. Adverse cardiovascular events occurred in 11 cases (8.3%) and clinically relevant bleeding events were reported in 5 cases (3.8%). A matched cohort was established after propensity score matching, resulting in 32 cases per group. The survival analysis found that the rate of aneurysm sac enlargement was significantly higher in the group receiving aspirin than that in the group not taking aspirin (Log-rank test: P=0.010), and the incidence of persistent type Ⅱ endoleak was significantly higher than that in the group not taking aspirin (Log-rank test: P=0.019). The incidence of adverse cardiovascular events and clinically relevant bleeding events were not significantly different in two groups (Log-rank test: P=0.061, P=0.286). Conclusions:The risk of aneurysm sac expansion and persistent type Ⅱ endoleak were significantly higher in patients taking long-term aspirin after EVAR than in the group not taking asprin. Therefore, high-risk abdominal aortic aneurysm patients who are prone to aneurysm sac expansion should be evaluated in advance so that the risks and benefits of surgery can be comprehensively evaluated and treatment strategies can be optimized.
