Objective To investigate the density,species composition,and seasonal prevalence of domestic rodents in different habitats within Lanzhou garrisons,providing basic information for rodent prevention and control.Methods A total of 12 monitoring sites were sampled across urban,suburban,and rural residential areas from 2014 to 2022.Rodent density was monitored using the night-trapping method in the middle of odd-numbered months.Results From 2014 to 2022,346 domestic rodents were captured using 122 035 effective traps,with an average domestic rodent density of 0.28％.The highest domestic rodent density was 0.63％in 2016,and the lowest was 0.07％in 2020,showing significant differences across years,with an overall trend of initially decreasing and then increasing(χ2=136.555,P<0.001).The dominant species was Rattus norvegicus,accounting for 83.24％of the total rodents captured.Rattus norvegicus accounted for a relatively high proportion across different years,with a statistically significant difference in species composition(χ2=20.931,P<0.05).Rodent densities and species composition also varied significantly among the monitored habitats(P<0.001),with the highest densities observed in rural residential areas and the lowest in urban areas.Seasonal variation in rodent densities showed a bimodal pattern,with smaller peaks in January or March and a larger peak in July.Conclusions Domestic rodent density in Lanzhou garrisons has shown an upward trend in the past few years.Rodent control measures should focus on barracks in rural residential areas,with targeted interventions to reduce the risk of rodent-borne diseases.

Objective:To analyze the gene mutation type and clinical phenotype of patients with PRRT2 mutation, and explore their relations with prognosis. Methods:A total of 18 patients with PRRT2 gene mutation (1 patient with novel mutation in PRRT2 gene, and 17 probands in 17 families with PRRT2 gene mutation) were enrolled in Department of Neurology, First Affiliated Hospital of Air Force Medical University from January 2018 to July 2023. Serum of the patients was collected for whole exon sequencing, and mutation sites and types of PRRT2 gene were analyzed. SWISS-MODEL website was used to predict the changes in protein structure caused by PRRT2 gene mutation. The relations of gene mutation type and clinical phenotype with prognosis of these patients were analyzed. Results:(1) All 18 patients with PRRT2 gene mutation were heterozygous mutation, including 12 frameshift mutations, 5 missense mutations, and 1 integer mutation. The clinical phenotype included benign familial infantile epilepsy (BFIE) in 5 patients, epilepsy in 6 patients, exercise-induced paroxysmal kinesigenic dyskinesia (PKD) in 5 patients, and infantile convulsion and choreoathetosis (ICCA) in 2 patients. A total of 8 mutation sites were found in 18 patients with PRRT2 gene mutation, of which 3 mutation sites have been reported, and 5 mutation sites have not been reported, including c.647(exon2)C>A, c.647(exon2)C>G, c.170(exon2)delC, c.981(exon3)C>G, and lossl(EXON: 2)(all). (2) Eighteen patients mainly accepted oxcarbazepine, levetiracetam, and sodium valproate in combination or monotherapy. Among them, 5 BFIE patients, 2 ICCA patients and 3 epilepsy patients were seizure-free after treatment. PKD patients did not respond well to oxcarbazepine. (3) Three frameshift mutations (mutation sites: c.649 [exon2]_c.650 [exon2] insC, c.640 [exon2]_c.641 [exon2] insC, and c.170 [exon2] delC) led to premature termination of protein translation, resulting in significant changes in protein structure. Four missense mutations (mutation sites: c.640[exo2]G>C, c.647[exon2]C>A, c.647[exon2]C>G, and c.981[exon3]C>G) had little effect on protein structure changes. No relation was found between changes of protein structure caused by different mutation types and prognosis. Conclusion:PRRT2 gene mutation patients with clinical phenotypes of BFIE and ICCA have good prognosis, but the mutation type is not related with the prognosis of patients.

Objective To evaluate the short-term efficacy and safety of catheter-directed thrombolysis(CDT)via femoral vein access and via anterior tibial vein access for lower extremity deep vein thrombosis(LEDVT).Methods The clinical data of 86 LEDVT patients,who were treated with CDT via healthy-side femoral vein access or via affected-side anterior tibial vein access at the Second Affiliated Hospital of Nanjing Medical University of China between January 2019 and December 2021,were retrospectively analyzed.Of the 86 patients,via femoral vein access was adopted in 40(FV group)and via anterior tibial vein access was adopted in 46(ATV group).The primary endpoints were the technical success rate and the thrombus removal rate.The secondary endpoints included the operation time and the complications.Results In the FV group and ATV group,the technical success rates were 92.5％and 100％respectively(P=0.097),the thrombus removal rates were(68.9+25.9)％and(78.3±21.0)％respectively(P=0.067),and the differences between the two groups were not statistically significant.The operation time in the FV group and ATV group was(64.1±14.8)min and(72.0±19.9)min respectively(P=0.037),and the difference between the two groups was statistically significant.The incidence of complications in the FV group and ATV group was 22.5％and 10.9％respectively(P=0.145),and the difference between the two groups was not statistically significant.Conclusion CDT therapy,regardless of via femoral vein access or via anterior tibial vein access,can effectively treat LEDVT with quite same clinical short-term efficacy and safety.

BACKGROUND: LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer. METHODS: We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels. RESULTS: On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]). CONCLUSION: LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile. TRIAL REGISTRATION ClinicalTrials.gov, NCT04563936.

【Objective】 To investigate the feasibility of laparoscopic simple prostatectomy (LSP) in the treatment of large volume benign prostate hyperplasia (BPH). 【Methods】 Clinical and follow-up data of 30 patients with large volume BPH treated with LSP in our hospital during Feb.2019 and Dec.2021 were retrospectively analyzed. All patients underwent extraperitoneal LSP operation. The perioperative and 1-12 month postoperative follow-up data were analyzed. 【Results】 The average prostate volume was (92.4±38.9) mL, operation time (125±45) min, and weight of resected prostate (60.25±16.90) g. The hemoglobin decreased by (12.21±7.25) g/d after operation. No blood transfusion was needed. There was no need for bladder irrigation after operation in 21 cases (70%), and 9 cases (30%) had bladder irrigation time of (0.95±0.49) d. The postoperative catheter indwelling time was (6.92±2.51) d, and hospital stay (5.36±1.63) d. During the follow-up of (9.25±5.4) months, there was 1 case of postoperative intestinal obstruction (Clavien-Dindo grade II), 1 case of transient urinary incontinence (Clavien-Dindo grade I), and 1 case of delayed hematuria (Clavien-Dindo grade I). No urethral stricture occurred. The maximum urinary flow rate (Qmax), post-void residual urine volume (PVR), International Prostate Symptom Score (IPSS) and quality of life (QoL) 3 months after operation were significantly improved compared with those before operation (P<0.05). There was no significant difference in sexual function before and after operation (P>0.05). 【Conclusion】 LSP is safe and effective in the treatment of large volume BPH. It has advantages of complete resection of glands, minor bleeding and short postoperative bladder irrigation time. However, it still needs to be confirmed by a prospective control study of large samples.

Objective: To explore the efficacy of adjuvant programmed cell death 1 (PD-1) monoclonal antibody immunotherapy in Chinese patients with resected stage Ⅱ-Ⅲ melanoma. Methods: A total of 296 patients who underwent radical surgery for stage Ⅱ-Ⅲ cutaneous orlimb melanoma at Fudan University Shanghai Cancer Center and Shanghai Electric Power Hospital between 2017 and 2021 and received adjuvant PD-1 monoclonal antibody immunotherapy, low-dose interferon (IFN), or observational follow-up were enrolled in this study. Patients were divided into the PD-1 monoclonal antibody group (164 cases) and the IFN or observation group (IFN/OBS group, 132 cases) based on postoperative adjuvant treatment methods. Patients' disease recurrence and survival were observed. Results: Among the 296 patients, 77 had cutaneous melanoma and 219 had limb melanoma; 110 were stage Ⅱ and 186 were stage Ⅲ. Among stage Ⅱ patients, the median recurrence-free survival (RFS) in the PD-1 monoclonal antibody group (46 cases) did not reach, while the median RFS in the IFN/OBS group (64 cases) was 36 months. The 1-year RFS rates were 85.3% and 92.1% and the 2-year RFS rates were 71.9% and 63.7% in the PD-1 monoclonal antibody group and the IFN/OBS group, respectively, with no statistically significant difference (P=0.394). Among stage Ⅲ patients, the median RFS rates in the PD-1 monoclonal antibody group (118 cases) and the IFN/OBS group (68 cases) were 23 and 13 months, respectively. The 1-year RFS rates were 70.0% and 51.8% and the 2-year RFS rates were 51.8% and 35.1%in the PD-1 monoclonal antibody group and the IFN/OBS group, respectively, with a statistically significant difference (P=0.010). Stratified analysis showed that the advantage of PD-1 monoclonal antibody adjuvant therapy in improving RFS persisted in the subgroups of primary ulceration (HR=0.558, 95% CI: 0.348-0.893), lymph node macroscopic metastasis (HR=0.486, 95% CI: 0.285-0.828), stage ⅢC (HR=0.389, 95% CI: 0.24-0.63), and the subgroup without BRAF/c-Kit/NRAS gene mutations (HR=0.347, 95% CI: 0.171-0.706). In terms of recurrence patterns, in stage Ⅱ patients, the recurrence and metastasis rate was 15.2% (7/46) in the PD-1 monoclonal antibody group, significantly lower than the IFN/OBS group [43.8% (28/64), P=0.002]. In stage Ⅲ melanoma patients, the recurrence and metastasis rate was 42.4% (50/118) in the PD-1 monoclonal antibody group, also lower than the IFN/OBS group [63.2% (43/68), P=0.006]. Conclusions: In real-world settings, compared with patients receiving low-dose IFN adjuvant therapy or observational follow-up, PD-1 monoclonal antibody immunotherapy can reduce the recurrence and metastasis rate of cutaneous and limb melanoma, and prolong the postoperative RFS of stage Ⅲ cutaneous and limb melanoma patients. Patients with a heavier tumor burden benefit more from immunotherapy.

Objective:To explore the expression of fructose bisphosphate aldolase A (ALDOA) in the bone marrow of patients with acute myeloid leukemia (AML) and the correlation with clinical features and prognosis.Methods:The bone marrow samples of 90 newly diagnosed AML (non-acute promyelocytic leukemia) patients and 18 allogeneic hematopoietic stem cell transplantation donors who were treated from January 2013 to December 2015 in the First Affiliated Hospital of Zhengzhou University and the Children's Hospital Affiliated to Zhengzhou University were collected. The relative expression level of ALDOA mRNA in bone marrow samples was detected by using real-time quantitative polymerase chain reaction (qRT-PCR). Clinical data of these patients were retrospectively analyzed, and the patients were divided into continuous complete remission (CR) group and refractory recurrent (RR) group according to the clinical response and follow-up results. The differences of the relative expression level of ALDOA mRNA between AML group and the normal control group, CR group and RR group were analyzed. Univariate and multivariate Cox regression risk model were used for analysis of factors influencing prognosis of AML patients.Results:The relative expression level of ALDOA mRNA in AML group was higher than that in normal control group [(5.71±0.44) vs. (1.10±0.08), t = 4.74, P<0.001]. The relative expression level of ALDOA mRNA in the RR group was higher than that in the CR group [(6.69±0.67) vs. (4.30±0.36) , t = 2.79, P < 0.001]. In addition, there were statistically significant differences in the proportion of patients with ALDOA mRNA high expression and those with ALDOA mRNA low expression stratified by the number of white blood cell, the proportion of bone marrow blasts and whether complete remission could be achieved or not after 1 course of induction therapy (all P < 0.05). Overall survival in patients with ALDOA high expression was worse than that in patients with ALDOA low expression ( χ2 = 5.59, P = 0.018). Multivariate analysis showed that white blood cell count, prognosis stratification, whether complete remission could be achieved or not after 1 course of induction therapy and ALDOA expression were the independent prognostic factors for the death of AML patients (all P < 0.05). Conclusions:ALDOA may play an important role in the development and progression of AML, and the expression level of ALDOA in the bone marrow can be used as an index for the prognosis assessment of AML patients and may be a potential therapeutic target for AML.
