Objective To explore the efficacy of ozone gas bath on necrotizing fasciitis after debride-ment.Methods Fifty patients with necrotizing fasciitis who underwent debridement in the First Affiliated Hospital of Guizhou University of Traditional Chinese Medicine from January 2020 to July 2024 were selected and divided into control group(25 cases)and observation group(25 cases)according to random number table method.The control group was given routine dressing change(normal saline,povidone iodine,hydrogen per-oxide,metronidazole sodium chloride injection),and the observation group was treated with ozone gas bath.The clinical efficacy,pain scores,laboratory indicators,postoperative complications,and total hospital days of the two groups were compared before and after treatment.Results Compared with the control group,the ob-servation group had a higher total effective rate(92.0%vs.68.0%),lower numerical rating scale for pain(NRS)scores at 1 week postoperatively,2 weeks postoperatively,and before discharge,as well as lower levels of WBC,C reactive protein(CRP),and procalcitonin(PCT),and a lower total incidence of complications(52.0%vs.80.0%).The hospital stay was shorter[(22.40±2.06)d vs.(29.28±2.28)d)],with statistical-ly significant differences(P<0.05).Conclusion Ozone gas bath can reduce postoperative pain and promote recovery in necrotizing fasciitis after debridement.

Objective:To investigate the effect of local anesthesia in patients with a PI-RADS score of 5 and ECOG score ≥2 for prostate puncture.Methods:Retrospective analysis of case data of 33 patients admitted to the Subei People's Hospital for prostate puncture from April 2020 to April 2022. Age (82.5±3.6) years. There were 18 cases with hypertensive disease, 8 cases with diabetes mellitus, and 6 cases with both diabetes mellitus and hypertensive disease. Body mass index (25.2±3.5) kg/m 2. prostate-specific antigen (PSA)(131.5±69.7) ng/ml. prostate volume (38.5±21.4) ml. all patients had a PI-RADS score of 5 on multiparametric magnetic resonance (mpMRI) and an Eastern Cooperative Oncology Group (ECOG) score ≥2. All 33 cases in this group underwent trans-perineal targeted prostate puncture using local anesthesia at the tip of the prostate. The visual analog score (VAS) and visual numeric score (VNS) were applied by the same surgeon to assess the patient's pain level and satisfaction at the time of puncture (VAS-1 and VNS-1) and 30 min after puncture (VAS-2 and VNS-2), and to record the duration of the procedure and the occurrence of postoperative complications. Results:In this group of 33 cases, the VAS-1 score was (1.9±0.3) and the VAS-2 score was (0.1±0.2); the VNS-1 score was (2.9±0.2) and the VNS-2 score was (3.9±0.1). Postoperative pathological results indicated that one of the 33 patients had a negative puncture result (pathology report indicating interstitial inflammation), while the rest of the patients had a positive puncture pathology report (puncture pathology report indicating prostate cancer), with a positive rate of 97%. One case of postoperative carnal haematuria occurred, which gradually improved after the patient was advised to drink water and take alpha-blockers. No perineal hematoma occurred, and all patients did not suffer complications such as urinary tract infection, urinary retention, azoospermia, vagal reaction, and infectious shock.Conclusion:In patients with a PI-RADS score of 5 and ECOG score ≥2, the use of single-hole local anesthesia for performing trans-perineal targeted puncture biopsy has the advantages of good paroxysmal pain and high safety.

The bioactive peptide could significantly promote the proliferation and insulin secretion from mouse islet MIN6 cells and rat islet INS-1 cells. The effect reached a climax at the concentration of 10 -5 mol/L. Conclusion:A novel bombesin bioactive peptide named QUB2995 was found from Hylarana Latouchii. It could significantly promote insulin secretion in MIN6 cells of mouse islets and INS-1 cells of rat islets, indicating its potential in the treatment of diabetes.

Objective:To explore the feasibility and safety of the clinical application of the diagnosis and treatment mode combining rapid frozen pathological examination of prostate biopsy tissue with radical prostatectomy.Methods:Suspected prostate cancer patients with PSA>10 ng/ml and PI-RADS score ≥4 in, Northern Jiangsu People's Hospital from April to September 2021 were collected. The included patients underwent mpMRI/TRUS image fusion-guided transperineal prostate targeted biopsy with 16G biopsy needle, 2-3 needles for biopsy, and rapid frozen pathological examination. Robot-assisted laparoscopic radical prostatectomy (RALP) was performed immediately for patients with prostate cancer with rapid freezing pathology. For undiagnosed prostate cancer, 18G biopsy needle for prostate targeted + systematic biopsy were used, 18-22 needles for systematic biopsy, and routine pathological examination. The baseline data, frozen pathological results, perioperative conditions, pathological results and follow-up data of all patients were collected.Results:Eleven patients were included in the study, the mean age of the patients was 69.9(66-73) years, the mean BMI was 22.8(19-26) kg/m 2, the mean PSA was 23.2(14.25-32.00), the mean prostate volume was 45(32-52) ml, mean PSAD 0.54(0.33-0.75). PI-RADS score was 4 in 3 cases and 5 in 8 cases; digital rectal examination was positive in 5 cases. All 11 cases underwent rapid freezing and the pathological results showed that: 9 cases were prostate adenocarcinoma, and RALP was performed immediately. The operation time was 111.5(96-126) min, the intraoperative blood loss was 78.9(55-105) ml, and the postoperative extubation time was 4.3(3.5-5.0) days, postoperative hospital stay 5.8(5.0-6.5) days. Postoperative pathology showed that Gleason score 3+ 4=7 in 1 case, 4+ 3=7 in 3 cases, 8 points in 4 cases, and 10 points in 1 case; 3 cases had positive resection margins, and 1 case had seminal vesicle invasion, the average number of dissected lymph nodes was 10.9 (8.5-14.0), and there was no tumor metastasis. Pathological T staging included 2 cases of T 2b stage, 5 cases of T 2c stage, 1 case of T 3a stage, and 1 case of T 3b stage. Two patients were undiagnosed by rapid freezing pathology, of which one was prostate adenocarcinoma with a Gleason score of 4+ 3=7, and then received RALP; the other one was prostate inflammation. 11 patients were followed up; the postoperative follow-up time was 3-7 months, with an average of 5.2 months. Among the 10 patients who underwent RALP, 8 patients recovered urinary continence 2 weeks after surgery, and all recovered within 2 months after surgery. Three patients with positive surgical margins were given regular androgen deprivation therapy in the second week after surgery. PSA did not drop below 0.1 ng/ml in patients with positive margins and seminal vesicle invasion 3 months after surgery. No complications of Clavien grade Ⅰ or higher occurred after operation and during follow-up. Conclusions:For patients with high suspicion of prostate cancer, rapid frozen pathological examination of prostate biopsy tissue is performed. RALP is performed immediately for patients with prostate cancer. The results show that this diagnosis and treatment model could be safe and feasible.

Objective: To investigate the clinical value of modified transperineal template-guided prostate biopsy (mTTPB) in the detection of prostate cancer. Methods: A total of 217 patients were enrolled in this study. All the patients were randomly divided into 2 groups. The control group (n=112) underwent transperineal template-guided prostate biopsy (TTPB) which was traditional transperineal template-guided 11-region biopsy. On the basis of the control group, the apex of prostate was divided into four areas for biopsy in the observation group (mTTPB). The positive rate of apex and the incidence of complications were analyzed. The prostatic specimens from the radical prostatectomy underwent whole mount sections examination. The prostate biopsy results were compared with the postoperative pathological results. Results: The average age of the control group and the observation group were (68.5±7.9) years and (67.3±8.5) years, PSA were (31.2±18.9) ng/ml and (29.7±19.5) ng/ml, prostate volume were (44.6±15.2) ml and (41.3±17.3) ml, respectively. In the control group, the positive rates of prostate cancer in 1-10 region were 24.1% (27/112), 27.7%(31/112), 23.2% (26/112), 28.6% (32/112), 26.8% (30/112), 25.0% (28/112), 26.8% (30/112), 19.6% (22/112), 25.9% (29/112), 25.0% (28/112), respectively, with an average of 25.3%. In the observation group, the positive rates in 1-10 region were 27.6% (29/105), 28.6% (30/105), 22.9% (24/105), 26.7% (28/105), 25.7% (27/105), 24.8% (26/105), 27.6% (29/105), 21.9% (23/105), 27.6% (29/105), 26.7% (28/105), respectively, with an average of 26.0%. There was no statistical difference between the two groups (P=0.904). The positive rate of apical prostate cancer in the control group and observation group was 37.5% (42/112) and 44.8% (47/105), respectively, and there was no statistical difference between the two groups (P=0.277). Patients were grouped according to PSA>20 ng/ml and PSA≤20 ng/ml. When PSA>20 ng/ml, the positive rate of apex was 58.6% (34/58) and 56.6% (30/53) respectively in the control group and the observation group, and there was no statistical difference between the two groups (P=0.830). When PSA≤20 ng/ml, the positive rate of apex was 14.8% (8/54) in the control group and 32.7% (17/52) in the observation group, with statistically significant differences (P=0.030). Before radical prostatectomy, 12 cases (57.1%) in the control group and 19 cases (73.1%) in the observation group showed apical invasion by biopsy. Results of whole mount sections examination in the control group showed that there were 19 cases (90.5%) with apical invasion, which was statistically different from that before surgery (P=0.035). The results of whole mount sections examination in the observation group showed that there were 23 cases (88.5%) with apex invasion, which had no statistical difference compared with that before surgery (P=0.291). There were no significant differences in the incidence of hematuria, fever, urinary retention and perineal discomfort between the observation group and the control group (all P>0.05). Conclusions mTTPB can significantly improve the detection rate of apical prostate cancer without increasing the incidence of complications, especially for patients with PSA≤20 ng/ml. Hence is safe and efficacious.

Objective To evaluate the clinical efficacy of brachytherapy with 125I seeds implantation in patients with castration resistant prostate cancer (CRPC).Methods Twenty-eight patients with CRPC from February 2010 to December 2015 in Northern Jiangsu People's Hospital were analyzed retrospectively.Patients were divided into 2 groups according to different treatment methods.Control group (n =13) received endocrine therapy,and study group (n =15) underwent brachytherapy combined with endocrine therapy.The progression was defined as posttreatment prostate specific antigen (PSA) ≥ 125％ PSA of baseline level.PSA-progression-free survival (PFS),overall survival (OS) and quality of life (physical functioning,social functioning,general health,general physical discomfort,urinary symptoms and treatment-related symptoms) of 2 groups were compared using Kaplan-Meier analysis and log-rank test.Results The median PSA-PFS and OS of study group were 29(24,37) months and 37(32,50) months respectively,both of them were longer than those of control group (13(7,21) months,19(14,23) months;x2 =13.300,19.362,both P＜0.01).Comparing with control group,the physical functioning,social functioning,general health and general physical discomfort of study group were improved.Conclusion Brachytherapy can effectively prolong the survival of CRPC patients and improve the patients' life quality.

Objective To evaluate the erectile function following transperineal template-guided prostate saturation biopsy (TFPSB).Methods From June 2013 to October 2015,patients underwent prostate biopsy.All patients were indicated for biopsy according to the criteria of "Guidance on diagnosis and treatment of urology in China".Exclusion criteria include medical history of PCa,severe urinary tract infection,severe cardiovascular and cerebrovascular diseases or abnormal blood coagulation.All patients were divided into observation group (TT'PSB) or control group (traditional trans-perineal template-guided prostate biopsy,TTPB) according to patients' condition,pubic anatomy,PSA abnormality,rectal examination,imaging examination and pain tolerance,etc.Patients were evaluated for pre-biopsy erectile function with the international index of erectile function (IIEF-5).All pathology confirmed prostate cancer patients were excluded.Concomitant systemic diseases and medications that would interfere with erectile function were recorded.Patients who withdrew from the trial or used the drugs such 5-phosphodiesterase inhibitors for sexual activity improvement were excluded.Ninety-seven patients in observation group and 84 patients in control group underwent further evaluation with the IIEF-5 questionnaire at 1,3 and 6 months post-biopsy.Results The average age of the observation group and the control group were (64.1 ± 7.9) years and (61.8 ±8.9) years,PSA were (7.2 ± 3.7) ng/ml and (6.7 ± 3.4) ng/ml,prostate volume were (47.8 ±21.5)ml and (49.2 ±22.2) ml,and the BMI were (21.4 ±3.1) kg/m2 and (20.6 ±3.4) kg/m2,respectively.There was no significant difference between the two groups (P ＞ 0.05) in term of above patients' characteristics.The pre-biopsy IIEF-5 score of the observation group and the control group were 19.1 ±4.5 and 19.7 ±4.3,which had no significant difference (t =-0.890,P=0.375).One month after biopsy,the IIEF-5 of two groups were 17.4 ±4.8 and 18.2 ±4.5 respectively and both group had statistically significant difference when compared with pre-biopsy (both P ＜ 0.05),however,there was no statistical significance at 3 and 6 months after biopsy.Besides,no significant difference of the IIEF-5 score was detected between two groups in 1,3 and 6 months.Conclusions Although TTPSB may resulted in temporary (1 month) post-biopsy erection dysfunction,the erectile function recovered to pre-biopsy level at 3-6 months post-biopsy.TTPSB did not increase the risk of ED compared with traditional TTPB.
