[Objective] To compare the clinical efficacy of super pulse thulium laser enucleation of the prostate (SPThuLEP) with "open tunnel" and transurethral holmium laser enucleation of the prostate (HoLEP) in the treatment of benign prostatic hyperplasia (BPH), in order to provide reference for the treatment options of BPH. [Methods] The clinical data of 112 BPH patients treated in our hospital during Jan.2023 and Jul.2023 were retrospectively analyzed, including 65 treated with SPThuLEP with "open tunnel" and 57 with HoLEP.The operation time, postoperative hemoglobin decrease, postoperative bladder irrigation, catheter indwelling time, hospitalization time and complications were compared between the two groups.The changes of maximum urine flow rate (Qmax), international prostate symptom score (IPSS), quality of life score (QoL), postvoid residual (PVR) and prostate-specific antigen (PSA) were compared between the two groups before operation and one month after operation. [Results] All operations were successful without conversion to open or transurethral plasmakinetic resection.The postoperative decrease of hemoglobin in SPThuLEP group was lower than that in HoLEP group [(13.12±6.72) g/L vs. (21.02±6.51) g/L], with statistical difference (P<0.05). There were no significant differences in the operation time [(63.35±15.73) min vs.(61.02±17.55) min], postoperative bladder irrigation time [(1.07±0.45) d vs. (1.06±0.36) d], catheter indwelling time [(2.98±0.56) d vs. (3.01±0.63) d] and hospitalization time [(3.63±0.61) d vs.(3.79±0.76) d] between the two groups (P>0.05). No blood transfusion, secondary bleeding or unplanned hospitalization occurred, and there were no serious complications such as transurethral electroresection syndrome (TURS), urethral stricture and urinary incontinence.One month after operation, the Qmax, IPSS, QoL, PVR and PSA of the two groups were significantly improved compared with those before operation (P<0.05), but with no statistical difference between the two groups (P>0.05). [Conclusion] SPThuLEP with "open tunnel" has comparable efficacy as HoLEP in the treatment of BPH.With advantages of small amount of bleeding and high safety, this minimally invasive technique can be widely popularized in clinical practice.

Surgical treatment is one of the key approaches for non-small cell lung cancer (NSCLC). Regular postoperative follow-up is crucial for early detection and timely management of tumor recurrence, metastasis, or second primary tumors. A scientifically sound and reasonable follow-up strategy not only extends patient survival but also significantly improves quality of life, thereby enhancing overall prognosis. This consensus aims to build upon the previous version by incorporating the latest clinical research advancements and refining postoperative follow-up protocols for early-stage NSCLC patients based on different treatment modalities. It provides a scientific and practical reference for clinicians involved in the postoperative follow-up management of NSCLC. By optimizing follow-up strategies, this consensus seeks to promote the standardization and normalization of lung cancer diagnosis and treatment in China, helping more patients receive high-quality care and long-term management. Additionally, the release of this consensus is expected to provide insights for related research and clinical practice both domestically and internationally, driving continuous development and innovation in the field of postoperative management for NSCLC.

The accumulation of uremic toxins such as urea nitrogen, blood creatinine, and uric acid of patients with renal failure in vivo would lead to aggravated kidney damage. In this study, coated aldehyde oxy-starch (CAO) was used as an adsorbent to investigate its in vitro adsorption performance on renal failure indexes for urea, indoxyl sulfate (INS), monomethylamine (MMA), dimethylamine (DMA), uric acid (UA), and creatinine (Cr). The effects of variables such as pH, temperature, concentration, dosage, and time on the adsorption capacity of CAO were systematically investigated, employing analytical techniques of high-performance liquid chromatography (HPLC) and gas chromatography (GC). The results revealed that CAO exhibited a strong adsorption capacity for urea, INS, and MMA, alongside a moderate adsorption capacity for DMA, UA, and Cr. The adsorption kinetics and thermodynamic studies indicated that the adsorption of urea and UA by CAO were fitted in pseudo-first-order kinetics, and the adsorption isotherm aligned with the Freundlich adsorption model. The enthalpy change ΔH of urea in adsorption was in the range of 40 to 60 kJ·mol^-1, which demonstrated the presence of strong adsorption force due to the interactions of coordinating groups. The ΔH of UA was greater than 80 kJ·mol^-1, indicating the generation of chemical bonds during the adsorption. Both of them, Gibbs free energy ΔG was less than 0, within the range of -20 to 0 kJ·mol^-1, suggested that the adsorption of urea and UA by CAO occurred spontaneously as physical adsorption process. The adsorption entropy ΔS of urea and UA was > 0, which indicated an increase in entropy throughout the adsorption. The infrared spectroscopygram showed the formation of a chemical bond, specifically the imine bond, following the adsorption of urea by CAO, thereby indicating a chemical reaction during the adsorption. This study elucidates the adsorption mechanism of CAO on various indexes of renal failure, providing a scientific basis for its clinical usage.

BackgroundSevere mental disorders represent a major public health concern due to the high disability rates and substantial disease burden， which has garnered significant national attention and prompted their inclusion in public health project management systems. However， credible evidence regarding the current status of disease management and factors influencing disease stabilization among patients with severe mental disorders in Luzhou City， Sichuan Province， remains limited. ObjectiveTo investigate the current management status of patients with severe mental disorders in Luzhou City， Sichuan Province， and to analyze influencing factors of disease stabilization among patients under standardized care， so as to provide evidence-based insights for developing targeted management strategies to optimize clinical interventions for this patient population. MethodsIn March 2023， data were extracted from the Sichuan Mental Health Service Comprehensive Management Platform for patients with severe mental disorders in Luzhou City who received management between December 2017 and December 2022. Information on mental health service utilization and clinical status changes was collected. Trend analysis was conducted to evaluate temporal changes in key management indicators for severe mental disorders in Luzhou City. Logistic regression analysis was employed to identify factors influencing the disease stabilization or fluctuation of these patients. ResultsThis study enrolled a total of 20 232 patients. In Luzhou City， the stabilization rate and standardized management rate of severe mental disorders were 94.89% and 79.36% in 2017， respectively， which increased to 95.33% and 96.92% by 2022. The regular medication adherence rate rose from 34.42% in 2018 to 86.81% in 2022. In 2022， the regular medication adherence rate was 71.80% for schizophrenia， 55.26% for paranoid psychosis， and 51.43% for schizoaffective disorder. Multivariate analysis identified the following protective factors for disease stabilization： age of 18~39 years （OR=0.613， 95% CI： 0.409~0.918）， age of 40~65 years （OR=0.615， 95% CI： 0.407~0.931）， urban residence （OR=0.587， 95% CI： 0.478~0.720）， and regular medication adherence （OR=0.826， 95% CI： 0.702~0.973）. Risk factors for disease fluctuation included poor （OR=1.712， 95% CI： 1.436~2.040）， non-inclusion in care-support programs （OR=1.928， 95% CI： 1.694~2.193）， non-participation in community rehabilitation （OR=2.255， 95% CI： 1.930~2.634）， and intermittent medication adherence （OR=3.893， 95% CI： 2.548~5.946）. ConclusionThe stability rate， standardized management rate， and regular medication adherence rate of patients with severe mental disorders in Luzhou City have shown a year-by-year increase. Age， household registration status， economic condition， medication compliance， and community-based rehabilitation were identified as influencing factors for disease fluctuation in these patients. ［Funded by Luzhou Science and Technology Plan Project （number， 2022-ZRK-186）］

ObjectiveTo explore the incremental cost of central line-associated bloodstream infections （CLABSI） after central venous catheterization （CVC） in critically ill patients in the intensive care unit （ICU）， as well as the main cost of nosocomial infection prevention and control. By comparing these two costs， the medical personnel to pay more attention should CLABSI prevention and control from the perspectives of medical quality and economic benefits， and promote the implementation of prevention and control measures. MethodsCluster sampling was used to select 126 critically ill patients who underwent CVC in the ICU of a tertiary traditional Chinese medicine hospital from January 2021 to December 2023， including 65 cases in the CLABSI group and 61 in the non-CLABSI group. Patients’ data were retrospectively collected from the hospital medical records， including the disease type， gender， age， length of hospital stay， outcome， and hospitalization expenses. The costs of different hand hygiene methods and differing approaches to environmental cleaning and disinfection were analyzed and compared. ResultsThere were significant differences in the length of hospital stay （Z=-5.35， P<0.05） and total hospitalization expenses （Z=-6.79， P<0.05） between the CLABSI and non-CLABSI group. Total hospitalization expenses showed significant differences among patients with different lengths of hospital stay （H=43.01， P<0.05）， with much higher median one in those with 60 or more days of hospital stay than other patients. Greater differences of median total hospitalization expenses were found in males than in females （Z=-3.98， P<0.05）， as well as in patients aged 60-80 years than in patients of other ages （Z=-5.79， P<0.05）. ConclusionsThe occurrence of CLABSI significantly increases the ICU patients’ length of hospital stay and hospitalization expenses. There are differences in the costs of different hand hygiene methods and differing approaches to environmental cleaning and disinfection， but these costs are acceptable compared to the incremental costs directly attributable to CLABSI. Therefore， medical institutions should attach importance to the investment in prevention and control of nosocomial infections such as hand hygiene and environmental cleaning and disinfection， formulate practical， reasonable and feasible plans， and ensure their implementation， in order to avoid nosocomial infections， improve the medical quality， effectively control patients’ length of hospital stay and hospitalization costs， and strive to maintain patient safety.

Objective To analyze the pathogenic characteristics and drug sensitivity of candidaemia,and construct a short-term mortality risk prediction scoring model.Methods The clinical data of patients with candidaemia admitted to the 909 Hospital of Joint Logistics Support Force from January 2011 to December 2020 were retrospectively analyzed,and the composition of pathogen composition,drug sensitivity test results and incidence of hospitalized patients were analyzed.324 cases of candidaemia were randomly divided into modeling group(190 cases)and validation group(134 cases),and the risk factors were screened by binary logistic regression.According to the odds ratio(OR)score,the 30 day mortality risk prediction scoring model was constructed,and the predictive performance of the model was verified both in modeling and validation groups.Results 356 strains of Candida including 126 strains of C.albicans(35.39%),79 strains of C.tropicalis(22.19%),74 strains of C.parapsilosis(20.79%),48 strains of C.glabrata(13.48%),14 strains of C.guilliermondii(3.93%),8 strains of C.krusei(2.25%),and 7 strains of other Candida(1.97%)were detected in 336 patients with candidemia.The incidence of candidaemia among hospitalized patients increased from 0.20 ‰ in 2011 to 0.48 ‰ in 2020.The resistance rate of candida to amphotericin B was significantly lower than that of fluconazole,voriconazole and itraconazole(P＜0.05).Among the 324 cases included in the model,95 patients died in 30 days after diagnosis,and the mortality rate was 29.32%.The proportion of males,fever,and parenteral nutrition in modeling group was significantly higher than that in validation group(P＜0.05),while the proportion of chronic lung disease and surgical history within one month were lower than those in validation group(P＜0.05).Logistic regression analysis showed that chronic renal failure,mechanical ventilation,severe neutropenia,failure to receive anti-fungal treatment within 72 hours,and APACHE Ⅱ≥20 were risk factors for short-term death of candidaemia,the OR values were 3.179,1.970,2.979,2.080,and 2.399,and the risk scores were 6,4,6,4,and 5,respectively.The area under the curve(AUC)of the risk scoring model for modeling group was 0.792(95%CI 0.721-0.862),and the result of Hosmer-Lemeshow(H-L)test was P=0.305;The AUC of validation group was 0.796(95%CI 0.735-0.898),and the H-L test result was P=0.329.A risk score≤8 indicated a low risk group for short-term mortality,a score of 9-15 indicated a medium risk group,and a score≥16 indicated a high risk group.Conclusions The incidence of candidemia in hospitalized patients is increasing and the mortality is high.The risk prediction score model can effectively predict the short-term prognosis and facilitate the early identification of the prognosis.

Objective:To explore the clinical outcome of internal fixation in the treatment of AO C-type distal radius fracture accompanied with dorsoulnar fragment involving 1/8 to 1/3 of the articular surface of the lunate facet.Methods:A total of 55 patients of AO C-type distal radius fracture accompanied with dorsoulnar fragment involving 1/8 to 1/3 of the articular surface of the lunate facet from July 2017 to July 2022 in Tongji Hospital Affiliated to Tongji University were retrospectively analyzed. In the volar plate group (volar locking plate treatment alone), there were 22 cases, 11 males and 11 females, aged 56.7±10.1 years, 10 C1 type, 7 C2 type and 5 C3 type. There were 15 patients in the volar plate+dorsal plate group (treated with volar locking plate combined with dorsal plate), including 6 males and 9 females, aged 55.7±8.1 years old, 4 C1 type, 5 C2 type and 6 C3 type. In the volar plate+dorsal screw group (treated with volar locking plate combined with dorsal screw), there were 18 cases, 8 males and 10 females, aged 53.5±11.6 years, 7 cases of C1 type, 5 cases of C2 type, and 6 cases of C3 type. The operation time, postoperative radiographic indicators, wrist range of motion (ROM), disability of arm, shoulder and hand (DASH) score, visual analogue scale (VAS) and postoperative complications were evaluated and compared between the three groups.Results:All operations were successfully completed. Patients were followed up for 14.9 ± 2.2 months (range, 12-18 months), and the fracture healing time was 12.4±2.3 weeks (range, 9-16 weeks). The operative time of patients in the volar plate group, volar plate+dorsal plate group and volar plate+dorsal screw group was 54.3±7.6 min, 70.7±5.9 min and 65.8± 7.1 min, respectively. Patients in the volar plate group had less operative time ( F=27.04, P<0.001). The residual displacement of the dorsoulnar fragment in sagittal, coronal, and axial CT scans in the three groups were (1.3±0.8 mm, 0.6±0.4 mm, 0.7±0.4 mm), (1.1±0.8 mm, 0.6±0.4 mm, 0.6±0.6 mm), (1.4±0.8 mm, 0.7±0.4 mm, 0.7±0.5 mm). The displacement of the dorsoulnar fragment of the two groups of combined volar and dorsal internal fixation was smaller than that of the volar plate group ( P<0.05). The ROM of wrist flexion of the three groups at 3 months after operation were 44.2°±4.6°, 47.7°±5.9°, 48.8°±5.1°, the ROM of wrist extension were 39.8°±6.2°, 44.3°± 4.6°, 44.7°±5.1°, the wrist DASH scores were 23.0±4.2, 20.1±4.1 and 19.4±3.0, and the VAS were 2.3±1.2, 1.6±1.3 and 1.3±1.0, respectively. The ROM of wrist flexion and extension and DASH score in volar plate+dorsal plate group were better than those in volar plate group ( P<0.05). The ROM of wrist flexion and extension, DASH score and VAS in the volar plate+dorsal screw group were better than those in the volar plate group ( P<0.05). There were no significant differences in terms of the wrist ROM, DASH score and VAS at 12 months after operation among the three groups ( P>0.05). There were 2 patients in the volar plate group with reduction loss, 3 patients with wrist chronic pain; 1 patient in the volar plate combined with dorsal plate group with dorsal tendon irritation, and no complications in the volar plate combined with dorsal screw group. Conclusion:For AO C-type distal radius fractures accompanied with a dorsoulnar fragment involving 1/8 to 1/3 of the articular surface of the lunate facet, the use of combined volar and dorsal internal fixation can improve the reduction accuracy and stability of the dorsoulnar fragment, and contribute to the early rehabilitation of postoperative wrist joint function. The effect of combined dorsal screw is comparable to that of dorsal plate internal fixation, but the complications of screw internal fixation are less.

ObjectiveAt present, the matching reagents of commercially available rapid DNA instruments based on microfluidics chip technology are autosome short tandem repeat (STR) individual identification reagents. The non-recombining part of the human Y chromosome is widely used in forensic DNA analysis, particularly in cases where standard autosomal DNA profile is uninformative. Y-STR loci are useful markers to identify males and male lineages in forensic practice. In order to achieve rapid and fully integrated detection ofY-STR loci, this study constructed the RTyper Y27 microfluidic chip rapid detection system and validated the performance of this system. MethodsThe system was verified and evaluated by sensitivity, success rate, typing accuracy, peak height balance, sizing precision and accuracy, mock case sample tests, mixture detection ability, and inhibition tolerance. ResultsComplete Y-STR profiles can be obtained when the template amount of DNA standard 9948 was ≥8 ng, the number of blood cards was ≥3 pieces, and the number of oral swab scrapings was≥7 times. The success rate of fully integrated detection was 91.52%, and the concordance rates was 99.74% for 165 testing samples. The success rate of 115 blood spots in these samples was 90.43%, with a typing accuracy of 99.65%, the success rate of 50 buccal swabs was 94%, with a typing accuracy of 99.92%. There was no significant difference in typing accuracy between blood spots and buccal swab samples. The peak height ratio between different fluorescence channels was 89.81%. The standard deviation of allelic ladder for 10 runs was within 0.5 bp. The size differences between allele and corresponding allele in allelic ladder was within 0.5 bp. The maximum precision CV values within and between batches were 0.48% and 0.68%, respectively, which were lower than 15%. These data indicate that the system has good accuracy and precision. The system was capable of accurately typing oral swabs, blood cards, saliva cards, cigarette butts, blood swabs and seminal stains. Complete Y-STR profiles can be obtained and distinguish at the 1∶3 ratio of minor and major contributors in artificial male DNA mixtures. Complete Y-STR genotyping can be obtained under the interference of inhibitors, such as different concentrations of humic acid (50-400 mg/L), indigotin (20-100 nmol/L) and hemoglobin (100-500 μmol/L). ConclusionIn this study, the RTyper Y27 microfluidic chip rapid amplification system is combined with the Quick TargSeq 1.0 integrated system, and the Y-STR profile can be obtained in approximately 2 h. Through a series of verification experiments, the results show that the system has good repeatability, accuracy and stability, can meet the on-site Y-STR detection requirements, and can be used in forensic practice.
