[Objective] To evaluate the efficacy and safety of sacral neuromodulation (SNM) in the treatment of patients with benign prostatic hyperplasia (BPH) complicated with underactive bladder (UAB) who respond poorly to transurethral resection of the prostate (TURP). [Methods] A retrospective analysis was performed on 10 patients with BPH and UAB treated with TURP by the same surgeon in Zhongda Hospital Southeast University during Jan.2018 and Jan.2023.The residual urine volume was not significantly relieved after operation, and the maximum urine flow rate and urine volume per discharge were not significantly improved.All patients underwent phase I SNM, and urinary diaries were recorded before and after surgery to observe the average daily frequency of urination, volume per urination, maximum urine flow rate, and residual urine volume. [Results] The operation time was (97.6±11.2) min.During the postoperative test of 2-4 weeks, if the residual urine volume reduction by more than 50% was deemed as effective, SNM was effective in 6 patients (60.0%). Compared with preoperative results, the daily frequency of urination [(20.2±3.8) times vs. (13.2±3.2) times], volume per urination [(119.2±56.7) mL vs. (246.5±59.2) mL], maximum urine flow rate [(8.7±1.5) mL/s vs. (16.5±2.6) mL/s], and residual urine volume [(222.5±55.0) mL vs. (80.8±16.0) mL] were significantly improved, with statistical significance (P<0.05). There were no complications such as bleeding, infection, fever or pain.The 6 patients who had effective outcomes successfully completed phase II surgery, and the fistula was removed.During the follow-up of 1 year, the curative effect was stable, and there were no complications such as electrode displacement, incision infection, or pain in the irritation sites.The residual urine volume of the other 4 unsuccessful patients did not improve significantly, and the electrodes were removed and the vesicostomy tube was retained. [Conclusion] SNM is safe and effective in the treatment of BPH with UAB patients with poor curative effects after TURP.

With the widespread use of antibiotics, drug-resistant bacterial infections have become a significant threat to human health. Finding new antibacterial strategies that can effectively control drug-resistant bacterial infections has become an urgent task. Unlike small molecule drugs that target bacterial proteins, antisense oligonucleotide (ASO) can target genes related to bacterial resistance, pathogenesis, growth, reproduction and biofilm formation. By regulating the expression of these genes, ASO can inhibit or kill bacteria, providing a novel approach for the development of antibacterial drugs. To overcome the challenge of delivering antisense oligonucleotide into bacterial cells, various drug delivery systems have been applied in this field, including cell-penetrating peptides, lipid nanoparticles and inorganic nanoparticles, which have injected new momentum into the development of antisense oligonucleotide in the antibacterial realm. This review summarizes the current development of small nucleic acid drugs, the antibacterial mechanisms, targets, sequences and delivery vectors of antisense oligonucleotide, providing a reference for the research and development of antisense oligonucleotide in the treatment of bacterial infections.

Objective To analyze the relationship between bone cement leakage after balloon kyphoplasty(BKP)and balloon expansion pressure(BEP)in patients with osteoporotic vertebral compression fracture(OVCF).Methods The clinical data of 116 elderly patients with OVCF who received BKP in our hospital were retrospectively analyzed.All patients underwent X-ray examination and CT enhanced scan before surgery and 72 hours after surgery to evaluate the efficacy and the occurrence of bone cement leakage.According to whether the bone cement leaked or not,he patients were divided into the bone cement leakage group and the non-bone cement leakage group.The pain was assessed by visual analogue scale(VAS)score,and the disturbance of daily living was assessed by Barthel index score.The area under the curve(AUC)and optimal cut-off value of BEP and bone cement volume to predict bone cement leakage were analyzed using receiver operating characteristic(ROC)curve.The risk factors of bone cement leakage was analyzed by multivariate Logistic regression analysis.Results There were 82 cases of mono-segment operation,27 cases of double-segment operation,and 7 cases of three-segment operation,involving 157 vertebrae.The anterior vertebral height and posterior vertebral height,the local kyphosis Cobb angle at the sagittal plane,and thoracolumbar kyphosis angle after surgery were significantly corrected,and the VAS score and Barthel index score were better than those before surgery(P<0.05).The bone cement leakage after surgery occurred in 24 patients,including 1 case with pulmonary cement embolism.The intraoperative BEP and volume of bone cement in the bone cement leakage group were significantly higher than those in the non-bone cement leakage group(P<0.05).ROC curve analysis showed that both the intraoperative BEP(AUC=0.756)and bone cement volume(AUC=0.661)could predict cement leakage,with the optimal cut-off value of 135 psi and 6.08 mL,respectively.Multivariate Logistic regression analysis showed that BEP≥135 psi was a risk factor for bone cement leakage(OR=1.038,95%CI:1.018 to 1.058,P<0.001).Conclusion BKP is a safe and effective treatment for OVCF in elderly patients,higher BEP is a risk factor for cement leakage,and patients with BEP≥135 psi are at higher risk of bone cement leakage.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To analyze the therapeutic effect of sural neurocutaneous flap combined with antibiotic-impregnated calcium sulfate and autogenous iliac bone graft of chronic calcaneal osteomyelitis.Methods:A retrospective analysis was peformed in 29 patients with chronic calcaneal osteomyelitis treated with sural neurocutaneous flap combined with antibiotic-impregnated calcium sulfate and autogenous iliac bone graft in the Xi′an Honghui Hospital Affiliated to Xi′an Jiaotong University from April 2013 to January 2020. There were 19 males and 10 females, with the age of (45.38±12.85) years, ranged from 22 to 67 years. The course of disease was (16.00±6.96) months, ranged from 6 to 36 months. The skin defect area was (41.9±15.9) cm 2, ranged from 11.8 to 86.8 cm 2. The causes of injury: 18 cases of high fall, 6 cases of traffic accidents, 3 cases of heavy rolling, the remaining 2 cases were machine strangulation and sharp stab wounds. The inflammatory markers [white blood cell (WBC), erythrocyte sedimentation rate (ESR), procalcitonin (PCT), C reactive protein (CRP)] and bone healing time were recorded before operation, 2, 4, 8 weeks and 6 months after operation. During the follow-up period, the flap texture, survival were observed, and the ankle-posterior foot function recovery was evaluated by the American Association of Foot and Ankle Surgery (AOFAS) score were observed before and after the operation, and the incidence of complications were recorded. The measurement data were expressed as mean±standard deviation ( ± s), and the t-test was used for inter-group comparison; the levels of WBC, ESR, PCT and CRP at different time points before and after operation were compared by repeated measurement ANOVA, and the LSD t-test was used for pairwise comparison. Results:All the 29 patients were followed up for (14.51±6.10) months, ranged from 6 to 30 months. All the flaps survived without abrasion, ulceration, or skin protrusion, and all patients could walk normally with shoes. There were 28 cases of stage I bone healing, with an average of (5.87±2.07) months, ranged from 3 to 12 months. The inflammatory indexes was significantly decreased at different time points after operation ( P<0.05). There was no significant difference between 6 months and 8 weeks after operation ( P>0.05), while there was significant difference at other time points ( P<0.05). The ankle-posterior foot score of AOFAS at 6 months after treatment was significantly higher than that before treatment (83.44±7.93 vs 55.37±8.07), the differences was statistically significant ( P<0.05). The clinical efficacy of foot function recovery was excellent in 12 cases, good in 15 cases and fair in 2 cases among 29 patients .The excellent and good rate was 93.1% (27/29). One patient recurred 1 month after operation and was re-implanted with antibiotic-loaded calcium sulfate mixed autogenous iliac bone after debridement, no recurrence was found. The total complication rate was 31.0%, but there was no significant impact on the patient's life in the later period. All patients returned to daily life and work. Conclusion:The treatment of chronic calcaneal osteomyelitis with sural neurocutaneous flap combined with antibiotic-impregnated calcium sulfate and autogenous iliac bone graft can effectively control infection, reconstruct calcaneal and soft tissue structure, promote functional recovery of affected limb, and ultimately improve the patient′s quality of life.

Objective: To evaluate the predictive value of the proportion of hibernating myocardium (HM) in total perfusion defect (TPD) on reverse left ventricle remodeling (RR) after coronary artery bypass graft (CABG) in patients with heart failure with reduced ejection fraction (HFrEF) by ^99mTc-methoxyisobutylisonitrile (MIBI) single photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) combined with ¹⁸F-flurodeoxyglucose (FDG) gated myocardial imaging positron emission computed tomography (PET). Methods: Inpatients diagnosed with HFrEF at the Cardiac Surgery Center, Anzhen Hospital of Capital Medical University from January 2016 to January 2022 were prospectively recruited. MPI combined with ¹⁸F-FDG gated PET was performed before surgery for viability assessment and the patients received follow-up MPI and ¹⁸F-FDG gated PET at different stages (3-12 months) after surgery. Δ indicated changes (post-pre). Left ventricular end-systolic volume (ESV) reduced at least 10% was defined as RR, patients were divided into reverse remodeling (RR+) group and the non-reverse group (RR-). Binary logistic regression analysis was used to identify predictors of RR. Receiver operating characteristic (ROC) curve analysis was performed and the area under the curve (AUC) was calculated to assess the cut-off value for predicting RR. Additionally, we retrospectively enrolled inpatients with HFrEF at the Cardiac Surgery Center, Anzhen Hospital of Capital Medical University from January 2021 to January 2022 as the validation group, who underwent MPI and ¹⁸F-FDG gated PET before surgery. Echocardiography was performed before CABG and after CABG (3-12 months). In the validation group, the reliability of obtaining the cut-off value for the ROC curve was verified. Results: A total of 28 patients with HFrEF (26 males; age (56.9±8.7) years) were included in the prospective cohort. HM/TPD was significantly higher in the RR+ group than in the RR- group ((51.8%±17.9%) vs. (35.7%±13.9%), P=0.016). Binary logistic regression analysis revealed that HM/TPD was an independent predictor of RR (Odds ratio=1.073, 95% Confidence interval: 1.005-1.145, P=0.035). ROC curve analysis revealed that HM/TPD=38.3% yielded the highest sensitivity, specificity, and accuracy (all 75%) for predicting RR and the AUC was 0.786 (P=0.011). Meanwhile, a total of 100 patients with HFrEF (90 males; age (59.7±9.6) years) were included in the validation group. In the validation group, HM/TPD=38.3% predicted RR in HFrEF patients after CABG with the highest sensitivity, specificity and accuracy (82%, 60% and 73% respectively). Compared with the HFrEF patients in the HM/TPD<38.3% group (n=36), RR and cardiac function improved more significantly in the HM/TPD≥38.3% group (n=64) (all P<0.05). Conclusions: Preoperative HM/TPD ratio is an independent factor for predicting RR in patients with HFrEF after CABG, and HM/TPD≥38.3% can accurately predict RR and the improvement of cardiac function after CABG.

With the expansion of mpox virus infection from endemic to a global epidemic in 2022, the WHO declared that the mpox event constituted a Public Health Emergency of International Concern. Due to the high degree of gene sequence similarity among orthopox viruses and cross-reactive antibodies induced by orthoviruses, smallpox vaccination may affect the immune response induced by mpox virus infection. The analysis of the protective effects of smallpox vaccination against mpox virus infection will help define the focus of prevention and control. In this review, we clarify the protection of the smallpox vaccine against mpox virus infection by analyzing the correlation between smallpox vaccination, immune response status, and clinical data and providing evidence for the prevention, control, and strategies of mpox epidemics.

Objective: To investigate the influence of extending the waiting time on tumor regression after neoadjuvant chemoradiology (nCRT) in patients with locally advanced rectal cancer (LARC). Methods: Clinicopathological data from 728 LARC patients who completed nCRT treatment at the First Affiliated Hospital, Naval Medical University from January 2012 to December 2021 were collected for retrospective analysis. The primary research endpoint was the sustained complete response (SCR). There were 498 males and 230 females, with an age (M(IQR)) of 58 (15) years (range: 22 to 89 years). Logistic regression models were used to explore whether waiting time was an independent factor affecting SCR. Curve fitting was used to represent the relationship between the cumulative occurrence rate of SCR and the waiting time. The patients were divided into a conventional waiting time group (4 to <12 weeks, n=581) and an extended waiting time group (12 to<20 weeks, n=147). Comparisons regarding tumor regression, organ preservation, and surgical conditions between the two groups were made using the t test, Wilcoxon rank sum test, or χ² test as appropriate. The Log-rank test was used to elucidate the survival discrepancies between the two groups. Results: The SCR rate of all patients was 21.6% (157/728). The waiting time was an independent influencing factor for SCR, with each additional day corresponding to an OR value of 1.010 (95%CI: 1.001 to 1.020, P=0.031). The cumulative rate of SCR occurrence gradually increased with the extension of waiting time, with the fastest increase between the 9^th to <10^th week. The SCR rate in the extended waiting time group was higher (27.9%(41/147) vs. 20.0%(116/581), χ²=3.901, P=0.048), and the organ preservation rate during the follow-up period was higher (21.1%(31/147) vs. 10.7%(62/581), χ²=10.510, P=0.001). The 3-year local recurrence/regrowth-free survival rates were 94.0% and 91.1%, the 3-year disease-free survival rates were 76.6% and 75.4%, and the 3-year overall survival rates were 95.6% and 92.2% for the conventional and extended waiting time groups, respectively, with no statistical differences in local recurrence/regrowth-free survival, disease-free survival and overall survival between the two groups (χ²=1.878, P=0.171; χ²=0.078, P=0.780; χ²=1.265, P=0.261). Conclusions: An extended waiting time is conducive to tumor regression, and extending the waiting time to 12 to <20 weeks after nCRT can improve the SCR rate and organ preservation rate, without increasing the difficulty of surgery or altering the oncological outcomes of patients.
