Objective:To investigate the effect of laparoscopic splenectomy and azygoportal disconnection (LSD) on liver synthesis and development of liver cirrhosis.Methods:This is a prospective case series study.The clinical data of liver cirrhotic patients with portal hypertension who received LSD at the Department of Hepatobiliary Surgery of Northern Jiangsu People′s Hospital Affiliated to Yangzhou University from September 2014 to January 2016 were included. This study analyzed the diameter of the portal vein, the velocity of portal blood flow, the routine blood parameters, the liver function, the synthetic proteins of liver (antithrombin Ⅲ (AT-Ⅲ), protein S, protein C), and the serum content of liver fibrotic markers(collagen type Ⅳ, procollagen type Ⅲ, laminin, hyaluronidase). Repeated measures ANOVA was used for comparison between multiple groups, and least significance difference was used for post-hoc multiple comparison.Results:A total of 106 patients were included in the study, including 70 males and 36 females, aged (51.8±9.8) years(range: 28 to 75 years).Compared with the preoperative results, the diameter of portal vein and the velocity of portal vein decreased after surgery ( F=14.03, 12.15, respectively, both P<0.01). Compared with the preoperative results, the total bilirubin, albumin, prothrombin time, international normalized ratio, Child-Pugh score and classification were improved ( F=17.96, 56.01, 66.63, 35.83, 33.49, and 27.50, respectively, all P<0.01), and the AT-Ⅲ, protein S, protein C,collagen type Ⅳ, procollagen type Ⅲ, laminin and hyaluronidase levels were also improved ( F=47.87, 36.26, 18.02, 2.79, 14.58, 44.35, and 14.38, respectively, all P<0.01). Compared with the preoperative period, the diameter of portal vein was reduced from the first week to the 24 th month after surgery ( t=5.45 to 9.39, all P<0.01). Compared with the preoperative period, the velocity of portal vein blood from the first week after surgery to the 24 th month after surgery was decreased ( t=4.02 to 8.43, all P<0.01). Compared with the preoperative period, routine blood parameters (white blood count, hemoglobin, platelet count), liver function (total bilirubin, albumin, prothrombin time, international normalized ratio, Child-Pugh score), liver synthetic protein (AT-Ⅲ, protein S, protein C) and liver fibrotic markers (collagen type Ⅳ, procollagen type Ⅲ, laminin, hyaluronidase) were improved to varying degrees at the 24th month after surgery ( t=-20.46 to 11.93, all P<0.01). Conclusion:Preliminary findings show that LSD can reduce portal vein pressure, restore blood cell number, and improve liver synthesis function and the degree of liver fibrosis in patients with portal hypertension in liver cirrhosis.

ObjectiveTo investigate the effect of the herb pair Cuscutae Semen-Lycii Fructus on oxidative stress-induced blood-testis barrier dysfunction and spermatogenesis in the rat model of oligoasthenozoospermia （OAS） and decipher the mechanism based on the silent information regulator 1 （SIRT1）/nuclear factor erythroid 2-related factor 2 （Nrf2） signaling pathway. MethodsThirty-five male SD rats were randomized into a blank group （n=7） and a modeling group （n=28）. The OAS model was established by gavage of hydrocortisone aqueous solution combined with single factor electrical stimulation. The modeled rats were randomly assigned into the following groups： model， Cuscutae Semen-Lycii Fructus granules （3.2 g·kg^-1）， Cuscutae Semen-Lycii Fructus total flavonoids （0.34 g·kg^-1）， and L-carnitine （0.38 g·kg^-1）， and treated for 4 weeks. The sperm quality of rats was assessed by an automatic sperm analyzer. The levels of superoxide dismutase （SOD）， malondialdehyde （MAD）， and glutathione peroxidase （GSH-Px） in the testicular tissue were determined by enzyme-linked immunosorbent assay. Hematoxylin-eosin staining was employed to reveal the pathological changes in the testicular tissue and score the spermatogenic function. Transmission electron microscopy was employed to observe the ultrastructural changes of Sertoli cells. Western blot and Real-time PCR were employed to determine the protein and mRNA levels， respectively， of SIRT1， Nrf2， Occludin， zonula occludens-1 （ZO-1）， connexin 43 （CX43）， and β-catenin. ResultsCompared with the blank group， the model group showed decreased total sperm count and motility （P<0.05， P<0.01）， obvious damage in the testicular tissue and blood-testis barrier structure， reduced score of spermatogenic function （P<0.01）， declined levels of GSH-Px and SOD in the testicular tissue （P<0.05）， elevated level of MDA， and down-regulated protein levels of SIRT1， Nrf2， ZO-1， CX43， β-catenin， and occludin （P<0.05， P<0.01） and mRNA levels of SIRT1， Nrf2， ZO-1， CX43， and β-catenin in the testicular tissue （P<0.05， P<0.01）. After treatment， the testicular tissue， blood-testis barrier structure， and score of spermatogenic function （P<0.01） were improved in the Cuscutae Semen-Lycii Fructus granules group， Cuscutae Semen-Lycii Fructus total flavonoids group， and L-carnitine group. Compared with the model group， the treatment groups presented lowered levels of GSH-Px and SOD （P<0.05， P<0.01）， and the Cuscutae Semen-Lycii Fructus granule group showed a decline in MDA level. The protein and mRNA levels of SIRT1， Nrf2， ZO-1， CX43， β-catenin， and occludin were up-regulated in the Cuscutae Semen-Lycii Fructus granules group and total flavonoids group （P<0.05， P<0.01）. ConclusionThe herb pair Cuscutae Semen-Lycii Fructus can regulate the SIRT1/Nrf2 pathway to inhibit oxidative stress and alleviate the blood-testis barrier damage， thereby improving the spermatogenic function in the rat model of OAS. Total flavonoids may be the material basis for the therapeutic effect of Cuscutae Semen-Lycii Fructus.

Objective: To investigate the abnormal fluctuation of coagulation function indicators in pediatric Burkitt lymphoma patients, and to analyze its correlation with disease progression and prognosis. Methods: The data of 172 children with Burkitt lymphoma in Children's Medical Center, Shanghai Jiao Tong University School of Medicine from January 2020 to December 2023 were retrospectively analyzed, and 120 healthy children were used as control group. Plasma prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), fibrinogen (Fib), International standardized ratio (INR), D-dimer (D-D), fibrinogen degradation products (FDP), and antithrombin (AT) were measured. Appropriate statistical methods were used to compare the data between two groups, and the Cox regression model was employed to analyze the influencing factors. A P-value <0.05 was considered statistically significant. Results: Levels of D-D, FDP, INR, and PT were significantly higher in children with Burkitt lymphoma than in the healthy controls [median (P25, P75) for the case group: 0.35 (0.13, 1.22), 3.10 (1.30, 10.20), 1.16 (1.06, 1.24), 12.60 (11.43, 13.50); median (P25, P75) for the healthy control group: 0.10 (0.07, 0.15), 0.60 (0.20, 1.08), 1.06 (1.02, 1.13), 11.50 (11.00, 12.30)](P<0.05). Levels of D-D, FDP, INR, PT, and TT were significantly elevated in children with recurrence compared to those without recurrence [median (P25, P75) for the recurrent group: 0.44 (0.16, 1.42), 3.85 (1.50, 12.25), 1.17 (1.08, 1.24), 12.70 (11.73, 13.50), 16.20 (14.80, 17.80); median (P25, P75) for the non-recurrent group: 0.21 (0.11, 0.69), 2.00 (1.00, 6.85), 1.11 (1.03, 1.24), 11.90 (11.10, 13.43), 15.20 (14.50, 16.40)](P<0.05). Levels of D-D, FDP in children with metastasis were significantly higher than those without metastasis [median (P25, P75) for the metastatic group: 0.51 (0.17, 1.84), 4.38 (1.70, 13.45); median (P25, P75) for the non-metastatic group: 0.20 (0.11, 0.39), 1.50 (1.00, 3.10)] (P<0.05). Levels of D-D and FDP were significantly higher in children with advanced stage than in those with early stage [median (P25, P75) for the high-stage group: 0.33 (0.14, 1.20), 3.10 (1.40, 10.23); median (P25, P75) for the low-stage group: 0.12 (0.08, 0.24), 0.90 (0.50, 2.50)] (P<0.05). Levels of D-D and FDP in high-risk children were significantly higher than those of low-risk [median (P25, P75) for the high-risk group: 0.28 (0.13, 1.01), 2.90 (1.15, 9.65); median (P25, P75) for the low-risk group: 0.12 (0.08, 0.17), 0.80 (0.43, 1.98)] (P<0.05). Levels of D-D, FDP, INR, and PT were significantly higher in children with poor prognosis than in those with favorable prognosis [median (P25, P75) for the poor prognosis group: 1.76 (0.80, 2.72), 13.45 (7.20, 25.30), 1.19 (1.12, 1.32), 12.85 (12.10, 14.35); median (P25, P75) for the favorable prognosis group: 0.23 (0.12, 0.52), 2.00 (1.00, 4.80), 1.14 (1.05, 1.23), 12.30 (11.40, 13.40)] (P<0.05).

Conclusion: Patients with Burkitt lymphoma exhibit coagulation disorders, which are influenced by recurrence, metastasis, clinical stage, risk stratification, and prognosis. In clinical practice, it is crucial to prioritize the monitoring of coagulation indicators to facilitate timely detection of coagulation dysfunction.

OBJECTIVE: To explore the application value of infrared thermography in the design and harvesting of ultrathin anterolateral thigh perforator flaps. METHODS: Between June 2024 and December 2024, 9 cases of ultrathin anterolateral thigh perforator flaps were designed and harvested with the assistance of infrared thermography. There were 7 males and 2 females, aged 21-61 years (mean, 39.8 years). The body mass index ranged from 19.49 to 26.45 kg/m² (mean, 23.85 kg/m²). Causes of injury included 5 cases of traffic accident injuries and 4 cases of machine crush injuries. There were 3 cases of leg wounds, 2 cases of foot wounds, and 4 cases of hand wounds. After debridement, the size of wound ranged from 7 cm×4 cm to 13 cm×11 cm. The time from admission to flap repair surgery was 5-12 days (mean, 7 days). Preoperatively, perforator localization was performed using a traditional Doppler flow detector and infrared thermography, respectively. The results were compared with the actual intraoperative locations; a discrepancy ≤10 mm was considered as consistent localization (positive), and the positive predictive value was calculated. All 9 cases were repaired with ultrathin anterolateral thigh perforator flaps designed and harvested based on thermographic images. The size of flap ranged from 8 cm×5 cm to 14 cm×8 cm, with a thickness of 3-6 mm (mean, 5.2 mm). One donor site was repaired with a full-thickness skin graft, and the others were sutured directly. Postoperatively, anti-inflammatory, anticoagulant, and anti-vascular spasm treatments were administered, and follow-up was conducted. RESULTS: The Doppler flow detector identified 22 perforating vessels within the set range, among which 16 were confirmed as superficial fascia layer perforators intraoperatively, with a positive predictive value of 72.7%. The infrared thermograph detected 23 superficial fascia layer perforating vessels, and 21 were verified intraoperatively, with a positive predictive value of 91.3%. There was no significant difference between the two methods [OR (95%CI)=3.93 (0.70, 22.15), P=0.100]. The perforator localization time of the infrared thermograph was (5.1±1.3) minutes, which was significantly shorter than that of the Doppler flow detector [(10.1±2.6) minutes; MD (95%CI)=-5.00 (-7.08, -2.91), P<0.001]. Postoperatively, 1 case of distal flap necrosis healed after dressing change; all other flaps survived successfully. The skin grafts at donor site survived, and all incisions healed by first intention. All patients were followed up 3-6 months (mean, 4.7 months). No pain or other discomfort occurred at the donor or recipient sites. All patients with foot wounds could walk with shoes, and no secondary flap revision was required. Flaps in 3 hand wound cases, 2 foot wound cases, and 3 leg wound cases recovered light touch and pressure sensation, but not pain or temperature sensation; the remaining 2 cases had no sensory recovery. CONCLUSION Preoperative localization using infrared thermography for repairing ultrathin anterolateral thigh perforator flaps can help evaluate the blood supply status of perforators, reduce complications, and improve surgical safety and flap survival rate.

Objective:This study explored the effect of nanoparticle-encapsulated curcumin on the highly expressed multidrug resistance gene 1 （MDR1） in a human low-differentiated nasopharyngeal carcinoma cell line （CNE2）. Methods:Curcumin/chitosan deoxycholic acid nanoparticles were prepared, and the cells were subjected to different treatments: radiotherapy, empty carriers, curcumin, and curcumin-loaded nanoparticles. Cell survival was analyzed using the clonogenic assay, and assessments of apoptosis, MDR1 levels, and miR593 levels were conducted. Results:The cell survival fractions in the curcumin group and the curcumin-loaded nanoparticles group were significantly reduced. Notably, higher apoptosis rates were observed in cells treated with curcumin or curcumin-loaded nanoparticles compared to those that received only radiotherapy. Moreover, a decreased MDR1 level was noted in both the curcumin group and the curcumin-loaded nanoparticles group, with further reduction in MDR1 expression observed in the nanoparticle group （P<0.05）. Enhanced expression of miR593 was found in the curcumin group and the curcumin-loaded nanoparticles group, with a relatively higher level in the nanoparticle group （P<0.05）. Curcumin encapsulated in nanoparticles exhibited a stronger radiosensitizing effect. The combination of curcumin and radiotherapy effectively inhibited nasopharyngeal carcinoma （NPC） tumor growth, suppressed MDR1 expression, and enhanced miR593 levels. After inhibiting miR593, MDR1 expression increased. The radiosensitizing effect of curcumin-loaded nanoparticles was regulated by miR593 rather than being triggered by MDR1. Conclusion:Curcumin-loaded nanoparticles mediated enhanced expression of miR593, which in turn inhibited the transcription and translation of the MDR1 gene, thereby reducing the radioresistance of NPC and effectively restraining its growth.

Tongue squamous cell carcinoma (TSCC) is a prevalent malignancy that afflicts the head and neck area and presents a high incidence of metastasis and invasion. Accurate diagnosis and effective treatment are essential for enhancing the quality of life and the survival rates of TSCC patients. The current treatment modalities for TSCC frequently suffer from a lack of specificity and efficacy. Nanoparticles with diagnostic and photothermal therapeutic properties may offer a new approach for the targeted therapy of TSCC. However, inadequate accumulation of photosensitizers at the tumor site diminishes the efficacy of photothermal therapy (PTT). This study modified gold nanodots (AuNDs) with the TSCC-targeting peptide HN-1 to improve the selectivity and therapeutic effects of PTT. The Au-HN-1 nanosystem effectively targeted the TSCC cells and was rapidly delivered to the tumor tissues compared to the AuNDs. The enhanced accumulation of photosensitizing agents at tumor sites achieved significant PTT effects in a mouse model of TSCC. Moreover, owing to its stable long-term fluorescence and high X-ray attenuation coefficient, the Au-HN-1 nanosystem can be used for fluorescence and computed tomography imaging of TSCC, rendering it useful for early tumor detection and accurate delineation of surgical margins. In conclusion, Au-HN-1 represents a promising nanomedicine for imaging-based diagnosis and targeted PTT of TSCC.

Objective To explore the effects of sacral neuromodulation (SNM) on urodynamic parameters during the storage phase in patients with neurogenic bladder (NB), so as to provide reference for evaluating the efficacy of SNM. Methods A total 49 NB patients undergoing SNM at our hospital during Oct.2012 and May 2025 were enrolled. Baseline data and video-urodynamic parameters were collected. Changes in maximum cystometric capacity, maximum detrusor pressure during storage phase, and bladder compliance before and after treatment were assessed. Improvements in detrusor overactivity (DO) and vesicoureteral reflux (VUR) were also analyzed. Results Among the 49 patients,27 were male and 22 were female, with a mean age of (37.41±15.15) years, a median disease duration of 5.0 (2.0,15.5) years, and a median follow-up of 11 (1,32) months. Up to 37 patients (75.5%) received permanent sacral nerve pulse generator implantation (permanent implant group), while the remaining 12 were classified as the non-permanent implant group. Before and after the test period, all patients showed a significant increase in maximum cystometric capacity [ (218.0 (93.0,358.5) mL vs.300.0 (238.5, 400.0) mL, P<0.001], a decrease in maximum detrusor pressure during the filling phase [32.0 (13.5,71.0) cmH_2 O vs. 20.0 (9.0,50.0) cmH_2 O, P<0.001], and an improvement in bladder compliance [11.8 (8.3,25.6) mL/cmH_2 O vs.26.7 (8.6,44.1) mL/cmH_2O, P<0.001]. In the permanent implant group, comparisons before and after the test period showed an increase in maximum bladder capacity [ (239.16±147.23) mL vs. (312.24±121.83) mL, P<0.001], a decrease in maximum detrusor pressure during filling[32.0 (15.0,58.0) cmH_2 O vs.15.0 (9.0,41.0) cmH_2 O, P<0.05], and improved bladder compliance [10.8 (8.3,23.6) mL/cmH_2 O vs.28.6 (8.6,41.4) mL/cmH_2 O, P<0.001]. No statistically significant differences in these parameters before and after the test period were observed in the non-permanent implant group (P>0.05). A total of 17 patients in the permanent implant group underwent follow-up video urodynamics. Compared to pre-test values, significant improvements were observed in maximum detrusor pressure during filling, and bladder compliance both at the end of the test period and at the last follow-up (P<0.05). However, no statistically significant differences were found in maximum cystometric capacity, maximum detrusor pressure during filling, and bladder compliance between the end of the test period and the last follow-up (P>0.05). Among the 49 patients,21 had DO and 20 had VUR. Both DO and VUR showed improvement after the test period and at the last follow-up. Conclusion SNM can effectively improve storage function in NB patients, ameliorate detrusor overactivity and bladder compliance, and relieve or eliminate VUR in some patients. Long-term follow-up confirms that SNM provides stable therapeutic effects, demonstrating significant clinical value.

Background Sleep disturbances in children and adolescents have become a global public health concern,with pronounced issues in the Western China.Despite this,research on the prevalence of insomnia and its influencing factors among children and adolescents in Chongqing is still lacking.Objective To understand the prevalence of insomnia and analyze its influencing factors among children and adolescents in Chongqing,so as to provide references for clinical interventions and preventive strategies of insomnia.Methods A stratified random sampling method was used to select 9 969 children and adolescents in Chongqing from November to December 2021.Insomnia Severity Index(ISI)and a self-designed questionnaire on awareness of core mental health knowledge were administered.Binary Logistic regression analysis was used to identify the influencing factors of insomnia in this population.Results A total of 3 578 children and adolescents(35.89％)were found to have insomnia symptoms.There were statistically significant differences in the detection of insomnia symptoms among gender,ethnicity,education level,domicile,only-child status,parental education level,introversion/extroversion,parental relationship,average monthly per capita income,family history of mental illness,medical insurance coverage,living situation and understanding of mental health knowledge(P<0.05 or 0.01).Binary Logistic regression analysis identified several risk factors for insomnia,including female gender(OR=1.301,95％CI:1.192～1.419),ethnic minority status(OR=1.163,95％CI:1.015～1.333),junior high school for education level(OR=1.985,95％CI:1.774～2.220),senior high school for education level(OR=3.085,95％CI:2.749～3.462),non-only-child status(OR=1.127,95％CI:1.013～1.253),degree of harmony between parents is not high or not harmonious[(OR=1.846,95％CI:1.669～2.041 for relatively harmonious;OR=2.524,95％CI:2.214～2.877 for generally harmonious;OR=2.452,95％CI:1.999～3.007 for not very harmonious;OR=2.926,95％CI:2.307～3.710 for very discordant)]and incomplete medical insurance coverage(OR=1.218,95％CI:1.093～1.358).Protective factors included an extroverted personality(OR=0.838,95％CI:0.766～0.917),absence of family history of mental illness(OR=0.719,95％CI:0.549～0.941),junior high school for mother's education level(OR=0.822,95％CI:0.734～0.920),senior high school or secondary specialized school for mother's education level(OR=0.862,95％CI:0.752～0.988),college and above for mother's education level(OR=0.748,95％CI:0.633～0.884)and knowledge of mental health(OR=0.854,95％CI:0.778～0.937).Conclusion The problem of insomnia among children and adolescents in Chongqing is quite serious.Risk factors for insomnia include female gender,ethnic minority status,higher education levels,being a non-only child,poor family relationships and incomplete medical insurance.Conversely,an extroverted personality,absence of family history of mental illness,higher maternal education and knowledge of mental health serve as protective factors against insomnia.
