OBJECTIVE: To investigate the efficacy of 3D-printed navigation guided pudendal lead implantation on nervous regulation of lower urinary tract symptoms（LUTS） in male patients. METHODS: Twenty-eight male patients who underwent perineal nervous regulation treatment for LUTS in Gongli Hospital of Pudong New Area from October 2021 to October 2023 were randomly divided into observation group and control group. The technology assisted with 3D-printed navigation to regulate the genital nerves was used in observation group. And the patients in control group were treated with regulation of the genital nerves by routine puncture. Operation time of puncture, number of surgical punctures, and stimulator debugging time compared between the two groups. The improvement of postoperative symptoms and surgical complications of patients in the observation group were recorded as well. RESULT: A total of 12 male LUTS patients were included in the observation group, with an average age of 36.5±6.5 years, including 7 cases of frequent micturition, 3 cases of perineal pain, and 2 cases of dysuria. Four patients showed no significant improvement in symptoms, including two patients with pain and two cases of frequent micturition who did not undergo secondary surgery. While the other eight patients showed significant improvement in symptoms. The average time for successful puncture in control group was (21.13 ± 4.53) minutes, which was longer than that of the 3D-printed navigation group (［10.32 ± 3.42］ min) significantly (P<0.05). The average number of punctures in the ordinary puncture group was 5.62 ± 1.43, which was significantly higher than that in the 3D-printed navigation group (1.5 ± 0.56). There was no statistically significant difference in the average time for stimulator debugging between the two groups of patients. The conversion rate of the 3D-printed navigation group in the second phase was 66.7%, which was higher than that (37.5%) significantly (P<0.05). CONCLUSION 3D printing navigation of pudendal nerve electrode wire implantation can improve the accuracy of electrode implantation and the conversion rate to a certain extent, which has the advantages of reducing the difficulty of surgery.

Objective:To investigate the efficacy and adverse reactions of whole-lung low-dose radiotherapy (LDRT) in patients with severe/critical coronavirus disease 2019 (COVID-19).Methods:Eight patients with severe/critical COVID-19 treated in the Jiangyin Hospital Affiliated to Nantong University from January to June 2023 who were treated with whole-lung LDRT after deteriorating or failing to improve post-medical treatment were enrolled in this single-arm phase I clinical trial. They received anterior-posterior penetrating radiation in a supine or prone position, with a total dose range from 0.5 to 1.5 Gy and a dose weight ratio of 1∶1. The oxygenation status, inflammatory markers, and imaging changes before and after radiotherapy were analyzed, and patients were followed up for acute radiation-induced adverse reactions.Results:One week after LDRT, the SaO 2/FiO 2 or PaO 2/FiO 2 indices increased in seven patients (87.5%), inflammatory markers such as C-reactive protein (CRP) and interleukin-6 (IL-6) decreased in seven patients (87.5%), and chest CT/chest radiographs revealed a significant reduction in the extent of pneumonia involvement in 5 patients (62.5%). No evident acute radiation-related adverse reactions were observed. Conclusions:Whole-lung LDRT with a dose range from 0.5 to 1.5 Gy can reduce inflammatory markers, improve clinical symptoms, and promote inflammatory absorption in patients with severe/critical COVID-19 who responded poorly to medical treatment while not inducing acute adverse reactions.

Objective:To compare the diagnostic efficacy of 68Ga-PSMA-11 PET/ CT and multi-parameter magnetic resonance imaging (mpMRI) for pelvic lymph node metastases in prostate cancer patients who received neoadjuvant endocrinology or not after initial diagnosis. Methods:Data of 52 patients with moderate and high-risk prostate cancer admitted to Xijing Hospital from February to October 2023, aged (65.8±6.6) years, preoperative prostate-specific antigen (PSA) 26.67 (13.09, 84.89) ng/ml, were retrospectively analyzed. Before operation, there were 28 cases of cT 2stage, 16 cases of cT 3 stage and 8 cases of cT 4 stage. There were 22 cases of cN 0 and 30 cases of cN 1. All patients underwent 68Ga-PSMA-11 PET/CT and mpMRI at the same time, and were diagnosed positive lymph nodes in 28 and 21 cases, respectively. Risk stratification were high risk in 45 cases, and medium risk in 7 cases. According to the preoperative endocrine treatment, they were divided into the newly diagnosed group without treatment (24 cases) and the endocrine treated group (28 cases), whose ages were (65.0±7.1) years and (66.8±6.1) years, respectively. Preoperative PSA was 26.17 (16.73, 61.18) ng/ml and 27.32 (11.94, 130.18) ng/ml, respectively. Gleason scores ≤7 were in 10 cases (41.7%) and 6 cases (21.4%), and Gleason scores >7 were in 14 cases (58.3%) and 22 cases (78.6%), respectively. There were 15 (62.5%) and 13 (46.4%) cases of cT 1-2 stage, and 9 (37.5%) and 15 (53.6%) cases of cT 3-4 stage, respectively. There were 16 (66.7%) and 6 (21.4%) cases of stage N 0, 8 (33.3%) and 22 (78.6%) cases of stage N 1, respectively. There were 22 (91.7%) and 20 (71.4%) cases of stage M 0, 2 (8.3%) and 8 (28.6%) cases of stage M 1, respectively. PET/CT diagnosis of lymph node positive was in 9 cases (37.5%) and 19 cases (67.9%), and mpMRI diagnosis of lymph node positive was in 5 cases (20.8%) and 16 cases (57.1%). The number of positive lymph nodes diagnosed by PET/CT was 13 (72.2%) and 47 (90.1%), and the number of positive lymph nodes diagnosed by mpMRI was 8 (44.4%) and 32 (61.5%). There was no significant difference ( P>0.05). All patients underwent radical prostatectomy as well as enlarged pelvic lymph node resection. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of the two imaging examinations in the diagnosis of lymph node metastasis were compared according to the results of postoperative pathological examination of lymph nodes. Receiver operating characteristic (ROC) curve was used to compare the accuracy of the two imaging tests in the diagnosis of pelvic lymph node metastasis in the newly diagnosed untreated group and the endocrine treated group. Results:In this study, of 52 cases, 26 (50.0%) had positive lymph nodes by pathological examination. In this study, a total of 681 lymph nodes were dissected, with 70 lymph nodes (10.28%) being pathologically positive, and the positive rate of 26 patients was 17.99% (70/389). The PET/CT and mpMRI detection rates of 26 node-positive patients were 92.3% (24/26) and 57.7% (15/26), respectively. There were 9 (37.5%) and 17 (60.7%) lymph node positive patients in the untreated group and the endocrine therapy group, respectively. There were 320 and 361 lymph nodes were clear, with 18 (5.6%) and 52 (14.4%) positive lymph nodes, respectively. The detection rates of PET/CT and mpMRI were 88.89% (8/9) and 94.12% (16/17)in the untreated group, and 44.44% (4/9) and 64.71% (11/17)in the endocrine treated group, respectively. In the newly treated group, the area under the curve (AUC) of PET/CT and mpMRI for diagnosing positive lymph nodes were 0.911 and 0.689 ( P=0.027), the sensitivity were 88.9% and 44.4%, and the specificity were 93.3% and 93.3%, respectively. PPV were 88.9% and 80.0%, and NPV were 93.3% and 73.7%, respectively. In the endocrine therapy group, the AUC of PET/CT and mpMRI for lymph node positive diagnosis were 0.834 and 0.596 ( P=0.011), the sensitivity were 94.1% and 64.7%, the specificity were 72.7% and 54.5%, and the PPV were 84.2% and 68.8%, respectively. NPV were 88.9% and 50.0%, respectively. Conclusions:For prostate cancer patients, regardless of whether they receive neoadjuvant endocrine therapy, 68Ga-PSMA-11 PET/CT can accurately detect pelvic lymph node metastasis, and the diagnostic efficacy is significantly better than that of mpMRI.

OBJECTIVE: To investigate whether the combination of chemotherapy with staged Chinese herbal medicine (CHM) therapy could enhance health-related quality of life (QoL) in non-small-cell lung cancer (NSCLC) patients and prolong the time before deterioration of lung cancer symptoms, in comparison to chemotherapy alone. METHODS: A prospective, double-blind, randomized, controlled trial was conducted from December 14, 2017 to August 28, 2020. A total of 180 patients with stage I B-IIIA NSCLC from 5 hospitals in Shanghai were randomly divided into chemotherapy combined with CHM (chemo+CHM) group (120 cases) or chemotherapy combined with placebo (chemo+placebo) group (60 cases) using stratified blocking randomization. The European Organization for Research and Treatment of Cancer (EORTC) Quality-of-Life-Core 30 Scale (QLQ-C30) was used to evaluate the patient-reported outcomes (PROs) during postoperative adjuvant chemotherapy in patients with early-stage NSCLC. Adverse events (AEs) were assessed in the safety analysis. RESULTS: Out of the total 180 patients, 173 patients (116 in the chemo+CHM group and 57 in the chemo+placebo group) were included in the PRO analyses. The initial mean QLQ-C30 Global Health Status (GHS)/QoL scores at baseline were 57.16 ± 1.64 and 57.67 ± 2.25 for the two respective groups (P>0.05). Compared with baseline, the chemo+CHM group had an improvement in EORTC QLQ-C30 GHS/QoL score at week 18 [least squares mean (LSM) change 17.83, 95% confidence interval (CI) 14.29 to 21.38]. Conversely, the chemo+placebo group had a decrease in the score (LSM change -13.67, 95% CI -22.70 to -4.63). A significant between-group difference in the LSM GHS/QoL score was observed, amounting to 31.63 points (95% CI 25.61 to 37.64, P<0.001). The similar trends were observed in physical functioning, fatigue and appetite loss. At week 18, patients in the chemo+CHM group had a higher proportion of improvement or stabilization in GHS/QoL functional and symptom scores compared to chemo+placebo group (P<0.001). The median time to deterioration was longer in the chemo+CHM group for GHS/QoL score [hazard ratio (HR)=0.33, 95% CI 0.23 to 0.48, P<0.0010], physical functioning (HR=0.43, 95% CI 0.25 to 0.75, P=0.0005), fatigue (HR=0.47, 95% CI 0.30 to 0.72, P<0.0001) and appetite loss (HR=0.65, 95% CI 0.42 to 1.00, P=0.0215). The incidence of AEs was lower in the chemo+CHM group than in the chemo+placebo group (9.83% vs. 15.79%, P=0.52). CONCLUSION The staged CHM therapy could help improve the PROs of postoperative patients with early-stage NSCLC during adjuvant chemotherapy, which is worthy of further clinical research.

The aim of this study was to investigate the effect of baicalein on a Drosophila model of hereditary Parkinson's disease caused by gene mutations and to preliminarily elucidate the mechanism of baicalein in delaying hereditary Parkinson's disease. In this paper, PTEN-induced putative kinase 1 (PINK1)-RNAi Parkinson's Drosophila were used as the model group and wild-type Drosophila w¹¹¹⁸ were used as the control group. Different doses of baicalein and Madopa were administered to the model group to observe their effects on the life span, motor ability, the abnormal rate of wings, dopamine content and dopaminergic neurons of PINK1-RNAi Parkinson's Drosophila and their effects on mitochondrial dysfunction including adenosine triphosphate (ATP), mitochondrial DNA (mtDNA) and reactive oxygen species (ROS) content. The results showed that the effective administration doses of baicalein were 0.8 mg·mL^-1 for low concentration, 1.6 mg·mL^-1 for medium concentration and 3.2 mg·mL^-1 for high concentration, and the optimal administration dose of the positive drug Madopa was 0.1 μg·mL^-1. Baicalein and Madopa could significantly improve the life span, exercise ability and reduce the abnormal rate of wings of PINK1-RNAi male Drosophila (P < 0.05), and low dose baicalein showed the best effect; baicalein could improve the loss of dopaminergic neurons, and the effects of low dose and high dose were the best, but Madopa showed no significant effect; baicalein and Madopa had no significant effect on dopamine content (P > 0.05). Baicalein and Madopa could increase the ATP content of PINK1-RNAi male Drosophila (P < 0.05), and low dose baicalein showed the best effect; middle dose baicalein could significantly increase the mtDNA content of PINK1-RNAi male Drosophila (P < 0.05), but Madopa had no significant effect; baicalein and Madopa had no significant effect on ROS content (P > 0.05).

Objective: To evaluate the therapeutic efficacy of hematopoietic stem cell transplantation (HSCT) for Wiskott-Aldrich syndrome (WAS), and to analyze the factors related to the outcomes. Methods: The clinical data of 60 children with WAS received HSCT in Shanghai Children's Medical Center from January 2006 to December 2020 were retrospectively analyzed. All cases were treated with a myeloablative conditioning regimen with busulfan and cyclophosphamide, and a graft-versus-host disease (GVHD) prevention regimen based on cyclosporine and methotrexate. Implantation, GVHD, transplant-related complications, immune reconstitution and survival rate were observed. Survival analysis was performed by Kaplan-Meier method, and Log-Rank method was used for univariate comparison. Results: The 60 male patients had main clinical features as infection and bleeding. The age at diagnosis was 0.4 (0.3, 0.8) years, and the age at transplantation was 1.1 (0.6, 2.1) years. There were 20 cases of human leukocyte antigen matched transplantation and 40 mismatched transplantation; 35 patients received peripheral blood HSCT, and 25 cord blood HSCT. All cases were fully implanted. The incidence of acute GVHD (aGVHD) was 48% (29/60) and only 2 (7%) developed aGVHD of grade Ⅲ; the incidence of chronic GVHD (cGVHD) was 23% (13/56), and all cases were limited. The incidence of CMV and EBV infection was 35% (21/60) and 33% (20/60) respectively; and 7 patients developed CMV retinitis. The incidence of sinus obstruction syndrome was 8% (5/60), of whom 2 patients died. There were 7 cases (12%) of autoimmune hemocytopenia after transplantation. Natural killer cells were the earliest to recover after transplantation, and B cells and CD4⁺T cells returned to normal at about 180 days post HSCT. The 5-year overall survival rate (OS) of this group was 93% (95%CI 86%-99%), and the event free survial rate (EFS) was 87% (95%CI 78%-95%). EFS of non-CMV reactivation group is higher than that of CMV reactivation group (95% (37/39) vs.71% (15/21), χ²=5.22, P=0.022). Conclusions: The therapeutic efficacy of HSCT for WAS is satisfying, and the early application of HSCT in typical cases can achieve better outcome. CMV infection is the main factor affecting disease-free survival rate, which can be improved by strengthening the management of complications.

Objective: To explore the molecular features of chronic myelomonocytic leukemia (CMML) . Methods: According to 2022 World Health Organization (WHO 2022) classification, 113 CMML patients and 840 myelodysplastic syndrome (MDS) patients from March 2016 to October 2021 were reclassified, and the clinical and molecular features of CMML patients were analyzed. Results: Among 113 CMML patients, 23 (20.4%) were re-diagnosed as acute myeloid leukemia (AML), including 18 AML with NPM1 mutation, 3 AML with KMT2A rearrangement, and 2 AML with MECOM rearrangement. The remaining 90 patients met the WHO 2022 CMML criteria. In addition, 19 of 840 (2.3%) MDS patients met the WHO 2022 CMML criteria. At least one gene mutation was detected in 99% of CMML patients, and the median number of mutations was 4. The genes with mutation frequency ≥ 10% were: ASXL1 (48%), NRAS (34%), RUNX1 (33%), TET2 (28%), U2AF1 (23%), SRSF2 (21.1%), SETBP1 (20%), KRAS (17%), CBL (15.6%) and DNMT3A (11%). Paired analysis showed that SRSF2 was frequently co-mutated with ASXL1 (OR=4.129, 95% CI 1.481-11.510, Q=0.007) and TET2 (OR=5.276, 95% CI 1.979-14.065, Q=0.001). SRSF2 and TET2 frequently occurred in elderly (≥60 years) patients with myeloproliferative CMML (MP-CMML). U2AF1 mutations were often mutually exclusive with TET2 (OR=0.174, 95% CI 0.038-0.791, Q=0.024), and were common in younger (<60 years) patients with myelodysplastic CMML (MD-CMML). Compared with patients with absolute monocyte count (AMoC) ≥1×10(9)/L and <1×10(9)/L, the former had a higher median age of onset (60 years old vs 47 years old, P<0.001), white blood cell count (15.9×10(9)/L vs 4.4×10(9)/L, P<0.001), proportion of monocytes (21.5% vs 15%, P=0.001), and hemoglobin level (86 g/L vs 74 g/L, P=0.014). TET2 mutations (P=0.021) and SRSF2 mutations (P=0.011) were more common in patients with AMoC≥1×10(9)/L, whereas U2AF1 mutations (P<0.001) were more common in patients with AMoC<1×10(9)/L. There was no significant difference in the frequency of other gene mutations between the two groups. Conclusion: According to WHO 2022 classification, nearly 20% of CMML patients had AMoC<1×10(9)/L at the time of diagnosis, and MD-CMML and MP-CMML had different molecular features.

Objective:To study the efficacy of 68Ga-PSMA PET/CT in evaluating lymph node metastases (LNMs) in patients with prostate cancer (PCa). Methods:Patients who recieved 68Ga-PSMA PET /CT examination in the First Affiliated Hospital of Air Force Military Medical University from July 2021 to February 2022 were enrolled. The patients’ age was (64.4±6.1) years old, with median total prostate specific antigen (tPSA) 34.5 (6.1-99.0) ng/ ml, including PSA<10ng/ ml in 12 cases, 10-20ng/ ml in 21 cases, and > 20 ng/ml in 25 cases. Preoperative clinical staging: 1 case in T 1 stage, 38 cases in T 2 stage, 16 cases in T 3stage, 3 cases in T 4 stage. Preoperative Gleason score of 10 cases was <7, 20 cases was 7, and 28 cases was > 7. According to D 'Amico risk grouping criteria, there were 8 cases in the low-risk group, 20 cases in the medium-risk group and 30 cases in the high-risk group. Preoperative examination of 68Ga-PSMA PET/CT showed no distant metastasis such as visceral metastasis and bone metastasis. All patients underwent radical prostatectomy and pelvic lymph node dissection. The following patients were excluded: patients received preoperative prostate surgery, patients received endocrine therapy, chemotherapy and radiotherapy for prostate cancer before surgery, a history of other malignant tumors in the past 2 years, biopsy pathological diagnosis of neuroendocrine cell prostate cancer and other special types of prostate cancer, prior history of major pelvic surgery, etc. Radical prostatectomy was performed. 38 patients received laparoscopic surgery and 20 patients received robot-assisted laparoscopic surgery. The sensitivity and specificity of 68Ga-PSMA PET /CT for the diagnosis of lymph node metastasis of prostate cancer were calculated according to the comparison of lymph node metastasis in postoperative pathological results and preoperative examination. Results:Postoperative pathological diagnosis: Gleason score of 9 cases was <7, 19 cases was 7, and 30 cases was >7. 37 cases were in pT 2 stage, 17 cases in pT 3 stage, and 4 cases in T 4 stage. There were 12 cases (20.7%) of positive resection margin, and 7 cases (12.1%) of lymphatic fistula. There were 10 patients with lymph node metastasis diagnosed by 68Ga-PSMA PET/CT before surgery, and 17 positive lymph node regions. A total of 11 patients were pathologically positive in lymph nodes, and a total of 20 lymph nodes regions were positive. Based on the number of patients, the specificity and sensitivity of 68Ga-PSMA PET /CT in diagnosing lymph node metastasis in patients were 97.9% (46/47) and 81.2% (9/11), respectively. Based on the number of regional lymph nodes, the specificity and sensitivity of 68Ga-PSMA PET /CT for regional lymph node diagnosis were 99.4%(326/328) and 75.0%(15/20), respectively. The specificity of lymph node metastasis in the external iliac group, the internal iliac group and the obturator group were 100.0%(114/114), 99.1%(110/111) and 98.1%(101/103), and the sensitivity was 100.0%(2/2), 60.00%(3/5) and 69.2%(9/13), respectively. Conclusion:68Ga-PSMA PET/CT can be used as a strong tool for precise guidance of PLND in PCa patients.
