Objective:To observe the role of impulsivity in cognitive impairment in manic episodes of bipolar Ⅰ disorder(BPDTI)patients.Methods:180 cases of patients with BPDTI manic episodes admitted to our hospital from February 2024 to December 2024 were selected as the manic group,and another 180 cases of volunteers who were psychologically tested as normal during the same period were selected as the healthy group.The impulse Barratt-11 scale(BIS-11)and the MATRICS Consensus Cognitive Test(MCCB)were used to investigate and evaluate impulsivity and cognitive function,and correlation analysis and risk factor analysis were conducted.Results:In the BIS-11 scale,there was no statistically significant difference between the two groups in the unplanned factor(P＞0.05),but there were significant differences compared between the two groups in cognitive,motor factors,and total score(P＜0.05).The MCCB scores of the manic group in information processing speed,working memory,word learning,visual learning,social cognition,reasoning and problem solving,and attention vigilance were significantly lower than those of the healthy group(P＜0.05).The relationship between BIS-11 total score and cognitive impulsivity factor and MCCB total score and word learning showed there were negative correlation(P＜0.05);The exercise factor in the BIS-11 scale were negatively correlated with the MCCB total score and working memory factor(P＜0.05);The unplanned factor in the BIS-11 scale showed there were negative correlation with the MCCB total score,word learning(P＜0.05),and information processing speed.BIS-11,the number of years of education was an influencing factor for BPDTI mania(P＜0.05).Conclusion:BPDTI mania patients had high impulsivity and cognitive impairment,high impulsivity and number of years of education were influencing factors for mania,high impulsivity affected cognitive function through corresponding brain regions,aggravating the condition.

Objective:To evaluate the efficacy and feasibility of a domestically developed robotic surgical system based on fiber-optic dedicated line communication in cross-regional urological telesurgery.Methods:This was multicenter，single-arm，retrospective case series study. The data of patients who underwent urological telesurgeries using the telesurgical system between January 2023 and December 2024 were analyzed. The cohort included 59 patients from seven hospitals across China. Among the patients，47 were male（79.7%）and 12 were female（20.3%），with a median age of 63.0（56.0，68.0）years and a body mass index of（24.7 ± 3.0）kg/m 2. Surgical procedures included 32 radical prostatectomies，24 partial nephrectomies，one radical nephrectomy，one adrenalectomy，and one ureteral reconstruction. The perioperative indicators，pathological results and postoperative complications were analyzed. The network monitoring data were collected，and the perioperative data of patients，remote system monitoring data and costs were compared between the two communication modes of optical transport network（OTN）and cloud-connect network（CCN）. Results:All 59 remote surgeries were successfully completed，with a mean operative time of（138.0 ± 54.0）minutes，median intraoperative blood loss of 50.0（30.0，100.0）ml and a postoperative hospital stay of 5.0（4.0，6.0）days. No cases required reoperation，Clavien-Dindo grade ≥3 complications，or readmission. The geographical distance between the primary and remote surgical sites ranged from 450 to 2 800 km. Network monitoring revealed increased bidirectional latency with distance increasing：the shortest latency time（Hefei-Hangzhou，450 km）was（16.59 ± 0.80）ms，while the longest（Harbin-Hangzhou，2 200 km）latency time was（53.31 ± 0.31）ms. Average frame loss per procedure was 0?1.27 frames. The results of subgroup analysis comparing OTN and CCN communication modes showed no significant differences in operative time［（130.7 ± 70.5）minutes vs.（142.1 ± 42.9）minutes， P = 0.442］，postoperative hospitalization［6.0（4.0，8.0）d vs. 5.0（4.0，6.0）d， P = 0.581］，or readmission rates（0 vs. 0）. However，CCN demonstrated significant cost advantages with 500 RMB per operation vs. 3 000 RMB per operation for OTN. Conclusions:Urological telesurgery using fiber-optic communication is feasible. The CCN mode，with its cost-effectiveness，excellent usability，and multi-point interconnection flexibility，is currently the preferred communication model for telesurgical applications.

Insulin-like growth factor 2 (IGF2) is a critical endocrine mediator implicated in male reproductive physiology. To investigate the correlation between IGF2 protein levels and various aspects of male infertility, specifically focusing on sperm quality, inflammation, and DNA damage, a cohort of 320 male participants was recruited from the Women's Hospital, Zhejiang University School of Medicine (Hangzhou, China) between 1 st January 2024 and 1 st March 2024. The relationship between IGF2 protein concentrations and sperm parameters was assessed, and Spearman correlation and linear regression analysis were employed to evaluate the independent associations between IGF2 protein levels and risk factors for infertility. Enzyme-linked immunosorbent assay (ELISA) was used to measure IGF2 protein levels in seminal plasma, alongside markers of inflammation (tumor necrosis factor-alpha [TNF-α] and interleukin-1β [IL-1β]). The relationship between seminal plasma IGF2 protein levels and DNA damage marker phosphorylated histone H2AX (γ-H2AX) was also explored. Our findings reveal that IGF2 protein expression decreased notably in patients with asthenospermia and teratospermia. Correlation analysis revealed nuanced associations between IGF2 protein levels and specific sperm parameters, and low IGF2 protein concentrations correlated with increased inflammation and DNA damage in sperm. The observed correlations between IGF2 protein levels and specific sperm parameters, along with its connection to inflammation and DNA damage, underscore the importance of IGF2 in the broader context of male reproductive health. These findings lay the groundwork for future research and potential therapeutic interventions targeting IGF2-related pathways to enhance male fertility.

The aim of this investigation was to determine the optimal storage medium for testicular hypothermic transportation and identify the ideal concentration for the application of the protective agent 5-aminolevulinic acid (5-ALA). Furthermore, this study aimed to explore the underlying mechanism of the protective effects of 5-ALA. First, we collected and stored mouse testicular fragments in different media, including Hank's balanced salt solution (HBSS; n = 5), Dulbecco's Modified Eagle Medium/Nutrient Mixture F-12 (DMEM/F12; n = 5), and alpha-minimum essential medium (αMEM; n = 5). Storage of testicular tissue in HBSS preserved the integrity of testicular morphology better than that in the DMEM/F12 group ( P < 0.05) and the αMEM group ( P < 0.01). Testicular fragments were subsequently placed in HBSS with various concentrations of 5-ALA (0 [control], 1 mmol l -1 , 2 mmol l -1 , and 5 mmol l -1 ) to determine the most effective concentration of 5-ALA. The 2 mmol l -1 5-ALA group ( n = 3) presented the highest positive rate of spermatogonial stem cells compared with those in the control, 1 mmol l -1 , and 5 mmol l -1 5-ALA groups. Finally, the tissue fragments were preserved in HBSS with control ( n = 3) and 2 mmol l -1 5-ALA ( n = 3) under low-temperature conditions. A comparative analysis was performed against fresh testes ( n = 3) to elucidate the underlying mechanism of 5-ALA. Gene set enrichment analysis (GSEA) for WikiPathways revealed that the p38 mitogen-activated protein kinase (MAPK) signaling pathway was downregulated in the 2 mmol l -1 5-ALA group compared with that in the control group (normalized enrichment score [NES] = -1.57, false discovery rate [FDR] = 0.229, and P = 0.019). In conclusion, these data suggest that using 2 mmol l -1 5-ALA in HBSS effectively protected the viability of spermatogonial stem cells upon hypothermic transportation.

Objective To investigate the feasibility of a "pericardial lining" modified Bentall procedure for the treatment of patients with aortic root aneurysm. Methods This was a retrospective study that consecutively enrolled patients treated at the Affiliated Suzhou Hospital of Nanjing Medical University, The Affiliated Traditional Chinese Medicine Hospital of Southwest Medical University, and the First People's Hospital of Guangyuan from January 2023 to February 2024. Preoperative clinical data, imaging findings (including echocardiography and CT scans of the aortic root and the entire aorta), details of coronary artery management, surgical outcomes, and postoperative follow-up results were collected. All patients underwent the "pericardial lining" modified Bentall procedure: the aortic valve was replaced, and an autologous pericardial patch was divided into three equal leaflets based on the circumference of the aortic annulus measured by a valve sizer. These leaflets were then sutured to the aortic annulus. Fenestrations were created in two of the pericardial leaflets for anastomosis with the left and right coronary ostia. The pericardial leaflets were sutured to the wall of the aortic sinuses to form an integrated structure, thereby narrowing the sinus portion. A prosthetic vascular graft was anastomosed to the proximal and distal aorta, and no aortic root-to-right atrium shunt was created. Results A total of 5 patients, aged 37 to 68 years, were included. The preoperative Society of Thoracic Surgeons (STS) risk scores ranged from 2.8% to 3.9%. The diameter of the ascending aorta was 40-73 mm, the left ventricular end-diastolic diameter (LVEDD) was 45-71 mm, and the left ventricular ejection fraction (LVEF) was 47%-64%. Intraoperatively, the aortic cross-clamp time ranged from 85 to 180 min, and the cardiopulmonary bypass time ranged from 110 to 302 min. Postoperative follow-up echocardiography revealed that the ascending aortic diameter was 27-35 mm, LVEDD was 39-57 mm, and LVEF was 43%-61%. All surgeries were completed successfully with satisfactory immediate outcomes and no intraoperative complications. During the follow-up period, there was no mortality or reoperation. Conclusion For patients with aortic root aneurysm, the "pericardial lining" modified Bentall procedure yields satisfactory preliminary results, and the technique is demonstrated to be feasible.

China is facing the double burden of high incidence of lung cancer and tuberculosis epidemic. Lung cancer combined with tuberculosis has a high incidence and complexity in clinical practice. High-risk groups include immunocompromised people, long-term smokers and people with a history of tuberculosis. The coexistence of the two diseases not only increases the difficulty of diagnosis and treatment decision-making, but also increases the risk of treatment-related adverse reactions and drug interactions. The guideline was developed by Committee of Integrated Rehabilitation for Lung Cancer, Chinese Anti-Cancer Association; Chinese and Western Integrated Lung Cancer Committee of Chinese Anti-Cancer Association; Society of Tuberculosis, Chinese Medical Association, aiming to standardize the diagnosis and treatment of lung cancer complicated with pulmonary tuberculosis. The guideline emphasizes the core position of combined diagnosis of multimodal imaging, etiology and pathology. It is proposed that anti-tuberculosis and anti-tumor treatment should be coordinated under the framework of multidisciplinary team, and drug interactions and timing optimization should be paid attention to. For surgical treatment, minimally invasive resection combined with systematic lymph node dissection is recommended after infection control. Systemic therapy requires individualized risk stratification and dynamic monitoring of efficacy and adverse reactions. Based on evidence-based medicine and Chinese clinical practice, combined with the accessibility of drugs and technologies, this guideline proposes a whole-process management pathway covering screening, diagnosis, treatment and follow-up, in order to improve the prognosis and quality of life of patients.

Objective To compare the clinical efficacy of ligament advanced reinforcement system(LARS)and autoge-nous hamstring tendon plus high-strength suture in arthroscopic reconstruction of posterior cruciate ligament(PCL).Methods A total of 96 patients with simple PCL injury treated with arthroscopic posterior cruciate ligament reconstructive surgery admit-ted to our hospital between August 2019 and December 2021 were selected for complete follow-up.There were 78 males and 18 females,40 cases of left leg and 56 cases of right leg,the aged from 20 to 56 years old with an average of(32.50±8.68)years old.The transplants were divided into two groups:LARS group(52 cases)and autogenous hamstring tendon plus high-strength suture group(44 cases).In the LARS group,there were 42 males and 10 females;with an average age of(31.84±8.62)years old;body mass index(BMI)was(24.73±2.29)kg·m-2;7 mm LARS was used to reconstruct PCL.In the autologous tendon group,there were 36 males and 8 females,with an average age of(33.06±8.99)years old,BMI was(23.52±2.16)kg·m-2,and the PCL was reconstructed with four strands of hamstring tendons and three pieces of Ethibond suture.All patients underwent functional rehabilitation guided exercise and were followed up regularly after surgery to objectively evaluate the stability of the knee joint by KT-1000 measurement of knee relaxation,and subjective evaluation of knee function by Lysholm score,Tegner score,and International Knee Documentation Council(IKDC)score.Data from preoperative,3,6,and 12 month follow-up were collected and analyzed by SPSS software to compare postoperative recovery and ligament relaxation between the two groups of patients.Results Ninety-six patients were followed up for 12 months.KT-1000 measurement of knee joint in autoge-nous tendon group and LARS group before operation[(10.73±1.46)points vs(10.55±1.53)points],6 months after operation[(3.02±0.75)points vs(2.35±0.60)points],12 months after operation[(3.77±1.76)points vs(2.44±0.60)points].There was significant difference between the two groups at 6 and 12 months after operation(P＜0.05),but there was no significant dif-ference between the two groups at 3 months after operation(P＞0.05).In the autogenous tendon group and LARS group,before operation and 12 months after operation,total Lysholm score[(40.6±16.8),(91.25±6.35)points vs(51.92±18.52),(92.35±5.30)points],Tegner score[(1.8±0.7),(5.8±0.6)points vs(1.7±0.8)、(5.7±0.7)points]and total IKDC score[(54.50±6.33),(83.90±3.93)points vs(54.40±4.24),(83.62±3.64)points],the differences were statistically significant(P＜0.05),indicating that the knee function of the two groups was improved after surgery.At 3 and 6 months after operation in the autoge-nous tendon group and LARS group,the total Lysholm score[(65.86±11.54),(74.60±6.46)points vs(73.46±6.42),(86.73±4.62)points],Tegner score[(2.5±0.6),(3.5±0.5)points vs(4.3±0.7),(5.0±1.4)points],the total scores of IKDC[(55.78±2.68),(70.62±4.74)points vs(65.31±4.60),(79.71±2.93)points].The difference between two groups was statistically sig-nificant(P＜0.05).The results showed that the function of the knee joint in the LARS group was better than that the autologous tendon group.However,at 12 months after the operation,there was no significant difference in the score of knee joint function between the two groups(P＞0.05).The results showed that the stability of LARS group was better than that of autologous tendon group.Conclusion Both the autogenous hamstring tendon plus high-strength suture and LARS reconstruction can significantly improve the knee function and stability,with satisfactory postoperative results.Howervr the LARS provides superior postopera-tive stability.

Aim To explore the effect and mechanism of the artesunate(ART)on hepatocellular carcinoma(HCC).Methods The cell lines MHCC-97H and HCC-LM3 were used to be detected.MTT and clone formation were used to determine the cell proliferation;Wound healing was used to detect the cell migration;Transwell was used to test the cell invasion.Flow-cy-tometry was used to detect cell apoptosis and cell cy-cle.RNA-seq and qRT-PCR was used to detect the genes expression.Results The proliferation,migra-tion and invasion of treated cells were obviously inhibi-ted(P＜0.01).Moreover,the apoptosis rate in-creased significantly,so did the proportion of G2/M cells.Transcriptomic analysis identified GADD45A as a potential target of ART through RNA-sequencing da-ta,and suggested that ART might induce apoptosis and cell cycle arrest through regulating the expression of GADD45A.In addition,the results of mechanism studies and signaling analysis suggested that GADD45A had interaction with its upstream gene NACC1(nucle-us accumbens associated 1).Moreover,after ART treatment,the expressions of GADD45A and NACC1 were changed significantly.Conclusion ART may be a potential drug to resist HCC by affecting the expres-sion of GADD45A and its upstream gene NACC1,which provides a new drug,a new direction and a new method for the clinical treatment of HCC.
