Objective To investigate the genetic polymorphism of HPA-1 to-16 antigens in Zhejiang Han population.Methods A total of 120 samples from unrelated donors of Zhejiang were genotyped by Polymerase Chain Reaction with Sequence-Specific Primers(PCR-SSP).Results The allele frequencies of HPA-1b,-2b,-3b,-6bw,-15b were 0.0125,0.0542,0.3833,0.0125 and 0.4833,respectively.HPA-4b,-5b,-7bw,-8bw,-9bw,-10bw,-11bw,-12bw,-13bw,-14bw and-16bw alleles were not detected.The mismatch probability(MP) of HPA-3 and 15 were 0.36 and 0.37,respectively,in raneom platelet transfusion.Conclusion There is no difference of HPA polymorphism distribution between Han population in Zhejiang and those in other areas of China.The polymorphism of HPA-3 and-15 are more abundant than other HPA antigens,so they may cause alloimmunity in random platelet transfusion recipients and between mothers and fetuses.

Premature ejaculation (PE) is a common male sexual dysfunction that can have significant effects on a couple's relationship. Behavioral therapy and psychotherapy are both safe and effective methods of treating PE. Ancient Chinese fangzhongshu (sexual skills and methods), which reflects a summary of expert experiences in sexology, contains many therapies for sexual dysfunction that are similar to those used in behavioral therapy or psychotherapy. A brief introduction dealing with the latest definitions of PE and treatment strategies drawn from behavioral therapy and psychotherapy is provided. Typical therapies for PE from ancient Chinese fangzhongshu are listed and briefly analyzed in order to define their domain of applicability and instructions for use. Ancient Chinese fangzhongshu contains many effective and safe therapies for PE. It should be incorporated into modern medical practice after critical analysis, and its scientific aspects should be promoted as a way of improving reproductive health, both to benefit individuals affected by PE and to promote traditional Chinese culture. Based on an analysis of the condition of the individual patient, one or multiple therapies guided by fangzhongshu can be expected to have an effect on the patient. Ancient Chinese fangzhongshu is of great value and should to be popularized and applied as a remedy for PE.

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 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.

Objective:To investigate the factors affecting the effect of periprostatic nerve block (PNB), establish a prediction model of pain degree, and verify the prediction efficiency.Methods:The clinical data of 314 patients who underwent transperineal prostate biopsy in our hospital from June 2022 to January 2023 were retrospectively analyzed. The median age was 71 (65, 76) years, the median prostate-specific antigen (PSA) was 14.6 (10.70, 24.65) ng/ml, and the median puncture needle number was 21 (19, 23) needles, median prostate volume 45.86 (31.52, 67.96) ml, median body mass index (BMI)24.02(22.97, 25.33)kg/m 2, including 109 patients with a history of diabetes, 90 patients with a history of surgery, and 57 patients with a history of severe trauma. The patients were divided into mild pain group (1-3 points), moderate pain group (4-6 points) and severe pain group (7-10 points) according to the intraoperative visual analogue scale (VAS). According to the clinical characteristics, the factors affecting the effect of PNB were analyzed by univariate analysis and multiple ordered logistic regression method. R language was used to construct a nomogram model for predicting PNB effect, receiver operating characteristic (ROC) curve and calibration curve were drawn, and Hosmer-Lemeshow test was carried out to verify the prediction efficiency of the model. Results:The results of univariate analysis showed that 171 patients in the mild pain group had a median age of 71 (65, 75) years, a median PSA14.5 (9.6, 24.6) ng/ml, a median number of puncture needles of 20 (18, 22), and a median prostate volume of 34.94 (26.36, 45.12) ml, median BMI24.17(23.14, 25.79)kg/m 2, including 74 patients with a history of diabetes, 51 patients with a history of surgery, and 40 patients with a history of severe trauma; There were 110 patients in the moderate pain group, the median age was 71 (65, 76) years, the median PSA14.8 (11.03, 24.27) ng/ml, the median number of puncture needles was 23 (20, 24) needles, median prostatic volume 63.24 (49.14, 78.72) ml, median BMI23.91(22.58, 24.88)kg/m 2, including 26 patients with a history of diabetes, 29 patients with a history of surgery, and 10 patients with a history of severe trauma; In the severe pain group, 33 patients had a median age of 73 (67, 78) years, a median PSA14.6 (10.85, 34.80) ng/ml, and a median puncture needle number of 23 (22.5, 24) needles, median prostate volume 70.64 (61.50, 104.51) ml, median BMI24.32(23.00, 26.06)kg/m 2, including 9 patients with a history of diabetes, 10 patients with a history of surgery, and 7 patients with a history of severe trauma. The results of univariate analysis showed that the number of puncture needles ( P<0.01), prostate volume ( P<0.01), history of diabetes ( P=0.002) and history of major trauma ( P= 0.009) were the factors affecting the effect of PNB. Multiple logistic regression analysis showed that puncture needle number ( P=0.009), prostate volume ( P<0.01) and diabetes history ( P=0.041) were independent risk factors for PNB effect. The area under ROC curve (AUC) of the moderate and above pain prediction model was 0.872, P<0.01; the area under ROC curve of the severe pain prediction model was 0.817, P<0.01; the result of Hosmer-Lemeshow test of the moderate and above pain prediction model was χ2=5.001, P=0.757. The results of the severe pain prediction model were χ2=4.452 and P=0.814. The calibration curve was established, which showed that the prediction probability of pain degree was in good agreement with the actual risk. Conclusions:The number of puncture needles, prostate volume and history of diabetes are the risk factors affecting the effect of PNB. The prediction model of PNB effect based on this model can be used to predict the pain degree of patients undergoing prostate biopsy after PNB.

The present study retrospectively analyzed the clinical data of 137 patients who underwent prostate in North Jiangsu People's Hospital from June 2020 to May 2021. All patients underwent peripheral prostatic nerve block anesthesia (PPNB). The observation group received 1% ropivacaine 32 ml local, and the control group received the same dose of lidocaine. There was no significant difference in general data before puncture between the two groups ( P>0.05). All 137 cases were performed by the same surgeon. The number of puncture needles in the observation group and the control group was (20.2±2.8) and (20.2±2.9), respectively, and the difference was not statistically significant ( P>0.05). The visual analogue scores (VAS-1) of pain during puncture in the observation group and the control group were (2.62±0.74) and (2.48±0.79) points, respectively. The visual numeric score (VNS-1) was (3.03±0.88) points and (3.15±0.80) points, respectively, and there was no significant difference ( P>0.05). 30 min after puncture, VAS-2 was (0.48±0.53) points and (0.30±0.47) points, VNS-2 was (3.31±0.48) points and (3.55±0.71) points, respectively.The differences were statistically significant ( P<0.05). There was no significant difference in overall complication rate between the two groups ( P=0.661).

Objective To investigate the antigen presentation characteristics of dendritic cells (DC) and B cells in cardiac grafts. Methods The heart of BALB/c mice was transplanted into the abdominal cavity of C57BL/6J mice. CD45⁺ cells in the heart graft were extracted and sorted by flow cytometry at postoperative 5 d, and single cell RNA sequencing was performed. Taking DC and B cell subsets in cardiac grafts as the main study cells, the changing trend, antigen presenting ability and intercellular communication with T cells after heart transplantation were analyzed by bioinformatics analysis and flow cytometry. Gene ontology (GO) function enrichment difference analysis was adopted to prove the specific function and the reliability annotation of cell subsets. Results Germinal center-like B cell (GC-L B) was the B cell subset with the largest increase in quantity during the acute rejection phase, accounting for 87%. Classical DC (cDC) 2 was the only DC subset with a significant increase in quantity during acute rejection of heart transplantation, accounting for 44% of DC subset, and it occupied the highest communication intensity with T cells after heart transplantation. Mononucleated DC (moDC) and memory B cell (MBC) were the main transmitters of T cell input signals in non-transplanted hearts, whereas transformed into cDC2 and GC-L B during the acute rejection phase. Among them, MBC and GC-L B were the main sources of T cell input signals in non-transplanted hearts and heart grafts. Conclusions Compared with DC, B cells occupy a higher number and weight in the intercellular communication with T cells in non-transplanted hearts and heart grafts, prompting that the antigen presenting activity of B cells is more active and stronger than DC in the early stage of acute rejection of heart transplantation.
