Objective To investigate the etiology and treatment of dysuria shortly after holmium laser enucleation of the prostate (HoLEP) for benign prostatic hyperplasia (BPH), so as to improve the therapeutic efficacy. Methods A retrospective analysis was conducted on 1361 BPH patients who received HoLEP at our hospital during Mar. 2018 and Mar. 2025. All patients underwent ultrasound, computed tomography (CT), urethral probing or radiography, cystourethroscopy, and urodynamic testing. The causes, treatments and prognosis of dysuria after operation were summarized. Results ninety-eight patients (7.2%) experienced dysuria within 3 months after surgery, and all patients received initial urethral dilation. Among the 62 cases with urethral stricture, 28 were treated with urethral dilation (average of 8 sessions), 16 underwent external urethral incision, 8 underwent anterior urethroplasty, and 10 underwent transurethral plasma incision for urethral stricture. Of the 12 cases with residual prostate tissue, 5 underwent urethral plasma prostatectomy and 7 received medication. All of the 12 cases with bladder neck contracture underwent transurethral plasma incision of the bladder neck and local drug injection. Five cases with intravesical blood clots underwent urethral blood clot irrigation, 2 of which developed active bleeding and then underwent electrocoagulation. Four cases with detrusor dysfunction had catheters re-indwelled for one week followed by medication. Two cases with stone and one case with tissue fragment impacted in the urethra underwent urethral holmium lithotripsy and cystoscopic removal. All patients underwent reoperation successfully and experienced complete resolution or significant improvement of urinary difficulties. Conclusion A certain proportion of patients experience dysuria after HoLEP, with diverse etiologies. The combination of prevention and treatment can reduce the incidence of dysuria.

Objective:To investigate the effects of different doses of ionizing radiation on the changes in nicotinamide adenine dinucleotide phosphate (NADPH) oxidase and reactive oxygen species (ROS) levels in the intestines of mice.Methods:C57BL/6 mice aged 6-8 weeks were randomly assigned to four groups (0 Gy, 0.1 Gy, 0.2 Gy, and 0.5 Gy; n=10/group) and subjected to single whole-body irradiation using a 60Co γ-ray source at a dose rate of 13 mGy/min. At 20 weeks post-irradiation, jejunal, ileal, and colonic tissues were collected. Immunohistochemistry, Western blotting, and reverse transcription-polymerase chain reaction (RT-PCR) were employed to assess mRNA and protein expression of NADPH oxidase components. Hydrogen peroxide (H 2O 2) levels and the expression of Nuclear Factor-kappa B (NF-κB), a transcriptional regulator of Dual Oxidase 2 (DUOX2), were also measured. Results:Compared with the 0 Gy group, mice in the 0.5 Gy group exhibited shortened villus length in the jejunum, villus fusion in the ileum, and increased crypt spacing in the colon, with statistically significant differences ( t=2.48, P < 0.05). No significant differences were observed in other dose groups compared to the 0 Gy group ( P > 0.05).The expression of H 2O 2 in the jejunum, ileum, and colon of the 0.1 Gy group was significantly elevated compared to the 0 Gy group ( t=4.12, 3.12, 3.12; P < 0.05). In the 0.5 Gy group, H 2O 2 expression in the jejunum and colon increased nearly twofold relative to the 0 Gy group ( t=8.67, 8.69; P < 0.05).At 20 weeks post-irradiation, DUOX2 protein expression levels in the jejunum, ileum, and colon were markedly higher in irradiated mice than in the 0 Gy group ( t=3.03, 10.29, 2.74; P < 0.05). DUOX2 mRNA levels in the jejunum, ileum, and colon of the 0.1 Gy group were significantly upregulated compared to the 0 Gy group ( t=12.75, 4.12, 11.14; P < 0.05). Additionally, NOX4 mRNA expression increased in the jejunum of the 0.2 Gy group ( t=4.54, P < 0.05) and in the ileum of the 0.1 Gy group ( t=4.13, P < 0.05).The nuclear factor kappa-B (NF-κB), a transcriptional regulator of DUOX2, showed an upward trend in expression in the jejunum, ileum, and colon of the 0.1 Gy group compared to the 0 Gy group, with statistically significant differences ( t=8.73, 8.18, 7.02; P < 0.05). Conclusion:Low-dose radiation induces long-term effects on the intestinal tract. Specifically, 0.5 Gy irradiation causes mild morphological alterations in the jejunum, ileum, and colon, while 0.1 Gy irradiation promotes the upregulation of DUOX2, a NADPH oxidase, in intestinal tissues.

Objective: To analyze the timeliness of antir-etroviral therapy (ART) and its influencing factors among newly reported HIV/AIDS cases in Wenzhou City, Zhejiang Province from 2016 to 2023, so as to provide a reference for improving the ART effect of HIV/AIDS cases. Methods: Newly reported HIV/AIDS cases in Wenzhou City from 2016 to 2023 were selected as the research subjects. Demographic information, the situation of the first CD4+ T lymphocyte (CD4 cell) test, baseline CD4 cell count, and ART situation were collected through the Chinese Disease Prevention and Control Information System. The timely rate of ART was analyzed, and the influencing factors for timely ART among HIV/AIDS cases were analyzed using a multivariable logistic regression model. Results: A total of 4 500 newly reported HIV/AIDS cases in Wenzhou City from 2016 to 2023 were included, among which 3 679 were males, accounting for 81.76%, and 821 were females, accounting for 18.24%. The median age was 46.24 (interquartile range, 26.23) years. Among these cases, 3 606 received timely ART, with a timely rate of 80.13%. The timely rate of ART increased from 57.54% in 2016 to 91.97% in 2023 (P<0.05). Multivariable logistic regression analysis showed that unmarried/divorced/widowed (OR=0.769, 95%CI: 0.641-0.922), detainees (OR=0.492, 95%CI: 0.269-0.900), untimely first CD4 cell test (OR=0.278, 95%CI: 0.234-0.330), baseline CD4 cell count ≥200 cells/µL (OR=0.709, 95%CI: 0.595-0.843) or undetected (OR=0.131, 95%CI: 0.080-0.213) were associated with a lower timeliness for ART among HIV/AIDS cases. Conclusion From 2016 to 2023, the timely rate of ART among newly reported HIV/AIDS cases in Wenzhou City showed an upward trend, which was mainly affected by marital status, case source, timeliness of the first CD4 cell test, and baseline CD4 cell count.

Objective:To investigate the effects of mobile intelligent cognitive training(MICT)on cognitive function,ac-tivities of daily living,and quality of life of patients with mild to moderate cognitive impairment after stroke in the community. Method:Ninty-two patients with mild to moderate cognitive impairment after stroke in the community were randomly divided into experimental group(n=46)and control group(n=46).Both groups received comprehen-sive management,and the experimental group received additional MICT for 12 weeks.The Mini-Mental State Examination(MMSE),Montreal Cognitive Assessment(MoCA),Prospective and Retrospective Memory Ques-tionnaire(PRMQ),Modified Barthel Index(MBI),Functional Activities Questionnaire(FAQ),and Quality of Life Index(QLI)were assessed before,4 weeks and 8 weeks after treatment,and 1-month follow-up after the end of treatment. Result:Before treatment,there was no significant difference in all scores between the two groups(P＞0.05).After 6 weeks of treatment,the MMSE,PRMQ,MBI,FAQ,and QLI scores of the two groups were im-proved(P＜0.05),and the MoCA,MBI,and QLI scores of the experimental group were higher than those of the control group(P＜0.05);After 12 weeks of treatment and 1 month of follow-up,the scores of MMSE,MoCA,PRMQ,MBI,FAQ,and QLI were significantly improved in two groups(P＜0.05),and all scores of the experimental group were better than those of the control group(P＜0.05). Conclusion:MICT can improve cognitive function,activities of daily living,and quality of life in patients with mild to moderate cognitive impairment after stroke in the community,with efficacy lasting at least 1 month.

OBJECTIVE To observe the clinical efficacy of Erdong Xiaoke Formula in the treatment of type 2 diabetes dry eyes with yin deficiency and heat excess syndrome and its effect on serum interleukin 17(IL-17)and interleukin 1β(IL-1β),and to ex-plore the therapeutic mechanism of Erdong Xiaoke Formula.METHODS 110 cases of type 2 diabetes patients with dry eyes of yin deficiency and heat excess syndrome from Jiangsu Province Hospital of Chinese Medicine were enrolled and randomly divided into a treatment group and a control group,55 cases each.5 cases dropped out of the treatment group and 4 cases dropped out of the control group.The control group was given a basic hypoglycemic regimen combined with topical sodium hyaluronate eye drops.The treatment group was given Erdong Xiaoke Formula in addition to the treatment in the control group.The treatment course for both groups was 4 weeks.Changes in TCM syndrome scores of the two groups of patients were observed before and after treatment,and the clinical effica-cy of TCM was evaluated.Blood glucose and pancreatic islet function-related indicators[fasting blood glucose(FBG),fasting insulin(FINS),fasting C-peptide(FCP),postprandial 2 h blood glucose(PBG),insulin secretion function index(HOMA-β),insulin re-sistance index(HOMA)-IR)],ocular surface indicators[tear break up time(BUT),corneal sodium fluorescein staining(FL),Schirmer Ⅰ test(SⅠT)],and inflammation-related indicators(IL-17,IL-1β)were detected.The occurrence of adverse reactions in the two groups of patients was observed during the treatment period.RESULTS After treatment,the total scores of TCM syn-dromes in both groups were significantly reduced(P＜0.01),the treatment group was better than the control group(P＜0.01),and the total effective rate of TCM syndromes in the treatment group was higher than that of the control group(P＜0.01);SⅠT and BUT of pa-tients in both groups increased significantly(P＜0.01),and the treatment group was better than the control group(P＜0.05,P＜0.01);the FL of patients in both groups significantly reduced(P＜0.01),and there was no significant difference between the groups;the ser-um IL-17 and IL-1β of the patients in the treatment group decreased significantly(P＜0.01),which was significantly better than that of the control group(P＜0.05).There were no significant changes in blood glucose and pancreatic islet function-related indicators in the two groups before and after treatment(P＞0.05).During the treatment,no obvious adverse reactions were observed in the two groups.CONCLUSION Erdong Xiaoke Formula can improve SⅠT,BUT,FL and eye symptoms in patients with diabetic dry eye,effectively treat diabetic dry eye,and reduce ocular surface inflammation.Its mechanism may be related to reducing serum inflammato-ry factors IL-17 and IL-1β.

Objective: To analyze the spatio-temporal distribution characteristics of new HIV/AIDS cases at ages of 50 years and older in Wenzhou City from 2006 to 2020, so as to provide insights into precise control of AIDS. Methods : The data of new HIV/AIDS cases aged 50 years and older in Wenzhou City from 2006 to 2020 were collected from the China Information System for Disease Control and Prevention. The temporal and spatial distribution characteristics of new HIV/AIDS cases at ages of 50 years and older were identified using global and local spatial autocorrelation analyses and spatial-temporal scan analysis. Results: Totally 1 917 new HIV/AIDS cases aged 50 years and older were detected in Wenzhou City from 2006 to 2020, and there were 179 new HIV/AIDS cases in 58 townships ( streets ) from 2006 to 2010, 643 cases in 113 townships ( streets ) from 2011 to 2015 and 1 095 cases in 147 townships ( streets ) from 2016 to 2020, respectively. The distribution of new HIV/AIDS cases appeared positive spatial autocorrelations from 2006 to 2010 ( Moran's I value=0.05, Z=1.976, P=0.046 ), from 2011 to 2015 ( Moran's I value=0.08, Z=2.314, P=0.028) and from 2016 to 2020 (Moran's I value=0.18, Z=3.956, P=0.003 ). Spatial-temporal scan analysis identified two clusters. The primary cluster mainly covered 70 towns ( streets ) in Lucheng Distrct, Ouhai District, Longwan District, Economic and Technical Development Region, Rui' an City and Pingyang County of Wenzhou City from January 1, 2014 to December 31, 2020, with a cluster radius of 34.30 km [log likelihood ratio ( LLR )=192.84, RR=2.60, P<0.001], and the secondary cluster was located in Hongqiao Township of Yueqing City from January 1, 2009 to December 31, 2015, with a cluster radius of 0 ( LLR=90.60, RR=7.27, P<0.001 ). Conclusions The number of new HIV/AIDS cases aged 50 years and older appeared a tendency towards a rise in Wenzhou City from 2006 to 2020, with spatial clusters that were predominantly identified in urban areas, Rui' an City and Pingyang County of Wenzhou City.

Objective:To investigate the effects of finasteride combined with tamsulosin hydrochloride administered during the perioperative period on glandular microvessel density in patients with benign prostatic hyperplasia.Methods:Ninety patients with benign prostatic hyperplasia who received treatment in Wenzhou Hospital of Integrated Traditional Chinese and Western Medicine from August 2017 to August 2019 were included in this study. They were randomly assigned to receive either oral tamsulosin hydrochloride alone (control group, n = 45) or oral finasteride combined with tamsulosin hydrochloride (observation group, n = 45) during the perioperative period of transurethral resection of the prostate. All patients received 6 weeks of medication. Clinical efficacy, adverse reactions, and urodynamic indexes, glandular microvessel density, International Prostatism Symptom Score, bother score, and urine color/degree of haematuria score pre- and post-treatment were compared between the two groups. Results:The maximum urinary flow rate in each group significantly increased 6 weeks after treatment compared with before treatment. The detrusor pressure and residual urine volume in each group decreased 6 weeks after treatment compared with before treatment. After 6 weeks of treatment, the maximum urinary flow rate was significantly higher in the observation group than in the control group [(15.63 ± 2.26) mL/s vs. (13.14 ± 2.23) mL/s], and residual urine volume was significantly lower in the observation group than in the control group [(29.19 ± 4.81) mL vs. (32.25 ± 5.52) mL, t = 5.26, 2.80, both P < 0.05). International Prostatism Symptom Score measured 6 weeks after treatment and urine color/degree of haematuria score measured 1 week after treatment were (12.09 ± 2.17) points and (1.51 ± 0.27) points, respectively in the observation group, which were significantly lower than those in the control group [(14.28 ± 2.22) points, (2.03 ± 0.38) points, t = 4.73, 7.48, both P < 0.05]. Factor VIII related antigen- and CD34-positive glandular microvessel density values in the observation group were (14.74 ± 3.05) counts/visual field and (19.41 ± 3.07) counts/visual field, respectively, which were significantly lower than those in the control group [(18.08 ± 3.16) counts/visual field, (22.27 ± 3.16) counts/visual field, t = 5.10, 4.35, both P < 0.05]. The incidence of postoperative hematuria was significantly lower in the observation group than in the control group [15.56% (7/45) vs. 35.56% (16/45), χ2 = 4.73, P < 0.05]. Conclusion:Compared with tamsulosin hydrochloride alone, finasteride combined with tamsulosin hydrochloride administered during the perioperative stage can greatly improve the urodynamic indexes of patients with benign prostatic hyperplasia, reduce microvessel density value, International Prostatism Symptom Score, bother score, and decrease the incidence of hematuria. The combined therapy provides a novel idea for preventing perioperative bleeding in patients with benign prostatic hyperplasia.

Background: Gastric mucosal atrophy and intestinal metaplasia (IM) are precancerous conditions of gastric cancer. Although Moluodan has been used in the treatment of chronic atrophic gastritis (CAG), there is little study on efficacy evaluation of Moluodan based on pathological stages. Aims: To assess the efficacy of Moluodan on reversal of gastric mucosal atrophy and IM based on OLGA and OLGIM staging systems, and to analyze the related factors. Methods: A total of 104 patients with CAG and IM from October 2019 to January 2022 at Xijing Hospital of Air Force Medical University were enrolled retrospectively in this study. All the patients received Moluodan treatment (one bag each time, three times daily) for 6 months. Changes of OLGA and OLGIM stages before and after treatment, and the related factors affecting the efficacy were analyzed. Results: After treatment with Moluodan for 6 months, the reversal rates for gastric mucosal atrophy and IM were 47.1% (49/104) and 51.0% (53/104), respectively, and the overall efficacy was 65.4% (68/104). There were 49.3% (34/69) and 52.4% (22/42) of patients with higher OLGA and OLGIM stages (III-) reversed to lower stages (0-Ⅱ), respectively. In addition, patients with OLGA and OLGIM stage III- showed a higher reversal rate than those with stage -Ⅱ (all P<0.01). No correlations were found between the demographic data, life and dietary styles, family history of gastric cancer, operation history, comorbidities, severity of mucosal inflammation and the efficacy of Moluodan (all P>0.05). Conclusions: Moluodan could reverse gastric mucosal atrophy and IM effectively in patients with CAG, which suggests that Moluodan has good potential in prevention of gastric cancer.
