Inguinal hernia is one of the most prevalent general surgical conditions affecting the elderly population.Currently, open or laparoscopic surgical repair represents the only curative approach.Among various surgical techniques, tension-free hernia repair via the preperitoneal space effectively addresses the complications associated with traditional surgical methods, such as excessive tension in the surgical area, postoperative pain and discomfort, and a subsequent decline in patients' quality of life.Nevertheless, a certain recurrence rate persists.This paper aims to highlight the insufficient research on preperitoneal hernia repair procedures within the field of hernia surgery and to conduct a comprehensive analysis of the primary factors contributing to postoperative recurrence.This analysis will be approached from three key perspectives: medical origins, individual patient variability, and the characteristics of the patch used.The goal is to provide a foundation for the theoretical framework and practical strategies aimed at reducing postoperative recurrence rates.

ObjectiveTo explore the effects of different dosage forms of Kaixinsan (KXS) on the morphology and function of mitochondria in rat models of Alzheimer's disease (AD) and potential mechanisms of action. MethodsMale SD rats were randomly assigned to a sham group, model group, treatment groups receiving KXS decoction, powders, and granules (3.08 g·kg-1), as well as donepezil group (0.51×10-3 g·kg-1), with 10 rats in each group. AD model was created using intracerebroventricular injection of streptozocin (STZ). After 30 days of administration, behavioral assessments were conducted, and mitochondrial morphology was observed using transmission electron microscopy. Mitochondrial respiratory chain complex content was measured via enzyme-linked immunosorbent assay (ELISA). Changes in mitochondrial membrane potential were measured via JC-1 staining, and superoxide dismutase (SOD) activity and reactive oxygen species (ROS) levels were measured via biochemical assays. The mRNA expression of adenosine 5'-monophosphate-activated protein kinase (AMPK), peroxisome proliferator-activated receptor gamma coactivator-1α (PGC-1α), and silent information regulator 3 (SIRT3) was detected by real-time fluorescent quantitative polymerase chain reaction (Real-time PCR), and Western blot was used to examine the protein expression levels of optic atrophy protein1 (OPA1), mitochondrial fission protein 1 (FIS1), AMPK, p-AMPK, PGC-1α, and SIRT3. ResultsCompared with the sham group, rats in the model group had significantly lower recognition index, spontaneous alternation rate, escape latency, number of platform crossings, time spent in the target quadrant, and percentage of distance traveled in the target quadrant distance (P<0.05, P<0.01). Significant mitochondrial damage was observed in the hippocampal tissue, with a marked decrease in mitochondrial respiratory chain complex content (P<0.01) and reduced mitochondrial membrane potential (P<0.05). Additionally, the SOD activity was reduced, while ROS levels were elevated (P<0.01). The mRNA expression of PGC-1α and SIRT3 was significantly downregulated (P<0.01), along with decreased protein expression levels of OPA1, p-AMPK/AMPK, PGC-1α, and SIRT3, whereas FIS1 protein expression was significantly upregulated (P<0.05, P<0.01). Compared with the model group, rats in KXS-treated groups (various dosage forms) showed significant improvement in behavioral indexes (P<0.05, P<0.01), reduced hippocampal mitochondrial damage, and more organized mitochondrial cristae. Mitochondrial respiratory chain complex content was significantly increased (P<0.05, P<0.01), and mitochondrial membrane potentials were elevated (P<0.05). SOD activity was elevated, and ROS levels were significantly reduced (P<0.05, P<0.01). Furthermore, the mRNA expression of PGC-1α and SIRT3 was upregulated, with increased protein levels of OPA1, p-AMPK/AMPK, PGC-1α, and SIRT3, while FIS1 protein expression levels were significantly reduced (P<0.05, P<0.01). Across the KXS-treated groups, the granule group showed a higher spontaneous alternation rate than the decoction and powder groups (P<0.05). ConclusionKXS decoction, powders, and granules can improve the learning and memory ability of rats, with granules being the most effective. The mechanism of action may involve activation of the AMPK/PGC-1α/SIRT3 signaling pathway, improvement of the mitochondrial function, and subsequent amelioration of the brain energy metabolism disorders.

Objective To explore the influencing factors for ischemic stroke in patients with unilateral moderate-to-severe extracranial internal carotid artery(ICA)stenosis and to construct a nomogram prediction model.Methods This study retrospectively and consecutively enrolled patients diagnosed with unilateral moderate-to-severe extracranial ICA stenosis and exhibited indications for carotid endarterectomy(CEA)hospitalized in the Department of Neurosurgery at the First Affiliated Hospital of Soochow University,between August 2019 and September 2024.The patients were divided into a stroke group and a non-stroke group,based on their clinical presentation and head MRI results.Baseline characteristics and clinical data including age,sex,body mass index,blood pressure(systolic and diastolic pressure[<140 mmHg,140-<160 mmHg,≥160 mmHg]),hypertension,diabetes,smoking and alcohol consumption history,use of statin and antiplatelet medication,fasting blood glucose,high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL-C),triglycerides(TG),total cholesterol(TC)were collected and ratios between LDL-C/HDL-C,TG/HDL-C,non-HDL-C(calculated according to equation:non-HDL-C=TC-HDL-C),and non-HDL-C/HDL-C(nHHR)were calculated based on aforementioned data.The clinical and baseline data were then compared between two groups.Imaging data included side of carotid artery stenosis(identified through neck vascular ultrasound,CT angiography and/or DSA),degree of carotid stenosis(with 50%-69%categorized as moderate stenosis,and,70%-99%as severe stenosis),plaque echogenicity(predominantly low,medium or high),plaque calcification(surface and basal calcification),plaque ulceration(exists or not),bilateral middle cerebral artery(MCA)hemodynamic parameters measured by transcranial Doppler ultrasound(including,mean flow velocity[Vm],peak systolic velocity[Vs],end-diastolic velocity[Vd]),and the pulsatility index(PI,calculated via formula:PI=[Vs-Vd]/Vm).The hemodynamic parameter differences(△Vm,△Vs,△Vd,△PI)between the healthy and affected MCA were calculated.The baseline,clinical and imaging data with P<0.05 in univariate analysis were included in multivariate Logistic regression analysis using forward stepwise selection to identify influencing factors for ischemic stroke in patients with unilateral moderate-to-severe extracranial ICA stenosis,and a nomogram prediction model was then constructed base on the analyzed results.Receiver operating characteristic curves were plotted,and the area under the curve(AUC)was calculated to evaluate the predictive performance of the nomogram.Delong's test was used to compare AUC differences between single indicators and the combined model.Results A total of 166 patients with unilateral moderate-to-severe extracranial ICA stenosis and CEA indication were included.In which,99 patients were in the stroke group and 67 patients were in the non-stroke group.The stroke group had a significantly higher proportion of hypertension patients(78.8%[78/99]vs.59.7%[40/67],P=0.008),higher systolic blood pressure([152±15]mmHg vs.[137±18]mmHg,P<0.01),higher diastolic blood pressure([84±10]mmHg vs.[80±10]mmHg,P=0.042),higher TG(1.33[0.95,1.77]mmol/L vs.1.10[0.87,1.48]mmol/L,P=0.019),higher TG/HDL-C(1.35[0.97,2.08]vs.1.07[0.81,1.52],P=0.003),and higher nHHR(2.89[2.25,3.61]vs.2.48[1.93,3.27],P=0.027)than the non-stroke group.The HDL-C was significantly lower in the stroke group(0.96[0.80,1.15]mmol/L vs.1.03[0.91,1.16]mmol/L,P=0.014).Statistically significant differences were also observed in the distribution of systolic blood pressure between the groups(P<0.01).No significant differences were found in other clinical data(all P>0.05).The proportion of patients with carotid plaque ulceration was higher in the stroke group(35.4%[35/99]vs.16.4%[11/67],P=0.007),while stenosis side,stenosis degree,plaque echogenicity,and plaque calcification type showed no significant differences between the groups(all P>0.05).△Vm(19[4,32]cm/s vs.10[-3,21]cm/s,P=0.001),△Vs(32[9,55]cm/s vs.24[3,40]cm/s,P=0.005),and △Vd(10[-1,19]cm/s vs.6[-3,12]cm/s,P=0.006)were significantly higher in the stroke group.No significant difference was found in △PI(P=0.076).Multivariate Logistic regression analysis identified high systolic blood pressure(OR,1.063,95%CI 1.036-1.090,P<0.01),high TG/HDL-C(OR,2.802,95%CI 1.551-5.061,P=0.001),high △Vm(OR,1.032,95%CI 1.010-1.055,P=0.004),and plaque ulceration(OR,2.777,95%CI 1.123-6.871,P=0.027)as independent risk factors for ischemic stroke in patients with unilateral moderate-to-severe extracranial ICA stenosis.Systolic blood pressure,TG/HDL-C,△Vm and plaque ulceration were involved in the construction of a combined predictive model for ischemic stroke in the targeted patient group(with unilateral moderate-to-severe extracranial ICA stenosis).The AUC of the combined prediction model was 0.828(95%CI 0.765-0.892,P<0.01),which was significantly higher than the predictive efficacy of any single factor(all P<0.01).Conclusions High systolic blood pressure,high TG/HDL-C ratio,high △Vm,and plaque ulceration are independent risk factors for ischemic stroke in patients with unilateral moderate-to-severe extracranial ICA stenosis.The nomogram prediction model based on these factors demonstrates good predictive value for assessing ischemic stroke risk in this patient population.

Objective:To explore the correlation between gross tumor volume (GTV) and prognosis of patients with esophageal cancer undergoing radiotherapy.Methods:A retrospective cohort study was conducted. The clinical data of 130 newly diagnosed esophageal squamous cell carcinoma patients who received radiotherapy at Shanxi Province Cancer Hospital from February 2016 to June 2018 were analyzed. All patients underwent conformal intensity-modulated radiotherapy (IMRT) for esophageal lesions. Pinnacle planning system was used to calculate GTV, and GTV classification was performed: GTV ≤ 30 cm 3 was classified as grade Ⅰ, GTV > 30 cm 3 and ≤ 60 cm 3 was classified as grade Ⅱ, and GTV > 60 cm 3 was classified as grade Ⅲ. Kaplan-Meier method was used to analyze the progression free survival (PFS) and overall survival (OS) of patients, and the multivariate Cox proportional hazards model was used to analyze the independent influencing factors of poor PFS and OS. Results:The median age of 130 patients [ M ( Q1, Q3)] was 59 years old (56 years old, 69 years old), with 90 males and 40 females; Karnofsky performance scores were all ≥ 70 points; tumors were located in the neck in 10 cases, upper chest in 34 cases, middle chest in 55 cases, and lower chest in 31 cases; clinical staging for esophageal carcinoma treated with non-surgical methods: 3 cases in stage Ⅰ, 37 cases in stage Ⅱ, 79 cases in stage Ⅲ, and 11 cases in stage Ⅳ; 25 cases were classified as GTV grade Ⅰ, 62 cases as GTV grade Ⅱ, and 43 cases as GTV grade Ⅲ. The 1-year PFS rate of 130 patients was 55%, the 2-year PFS rate was 19%, and the median PFS time was 14 months; the 1-year OS rate was 76%, the 2-year OS rate was 32%, and the median OS time was 20 months. PFS and OS of patients in stages Ⅰ+Ⅱ, Ⅲ and Ⅳ deteriorated sequentially, and the differences between the three groups were statistically significant (both P < 0.001); the PFS and OS of patients with GTV grades Ⅰ, Ⅱ and Ⅲ deteriorated sequentially, and the differences in PFS and OS between the three groups were statistically significant (both P < 0.001); there were no statistically significant differences in PFS and OS among patients of different genders, ages, and tumor locations (all P > 0.05). The results of multivariate Cox regression analysis showed that high clinical staging (stage Ⅳ vs. stage Ⅰ, HR = 8.34, 95% CI: 3.88-17.94, P < 0.001) and high GTV grading (grade Ⅱ vs. grade Ⅰ: HR = 6.81, 95% CI: 3.39-13.67, P < 0.001; grade Ⅲ vs. grade Ⅰ: HR = 23.97, 95% CI: 10.81-53.14, P < 0.001) were independent risk factors for poor PFS; high clinical staging (stage Ⅳ vs. stage Ⅰ: HR = 9.94, 95% CI: 4.50-21.97, P < 0.001) and high GTV grading (grade Ⅱ vs. grade Ⅰ: HR = 13.55, 95% CI: 5.58-32.91, P < 0.001; grade Ⅲ vs. grade Ⅰ: HR = 35.01, 95% CI: 13.57-90.34, P < 0.001) were independent risk factors for poor OS. Conclusions:GTV is associated with the prognosis of patients with esophageal cancer undergoing radiotherapy.

OBJECTIVE:
To carry out prenatal diagnosis and genetic analysis for a fetus with disorders of sex development (DSDs).
METHODS:
A fetus with DSDs who was identified at the Shenzhen People's Hospital in September 2021 was selected as the study subject. Combined molecular genetic techniques including quantitative fluorescence PCR (QF-PCR), multiplex ligation-dependent probe amplification (MLPA), chromosomal microarray analysis (CMA), quantitative real-time PCR (qPCR), as well as cytogenetic techniques such as karyotyping analysis and fluorescence in situ hybridization (FISH) were applied. Ultrasonography was used to observe the phenotype of sex development.
RESULTS:
Molecular genetic testing suggested that the fetus had mosaicism of Yq11.222qter deletion and X monosomy. Combined with the result of cytogenetic testing, its karyotype was determined as mos 45,X[34]/46,X,del(Y)(q11.222)[61]/47,X,del(Y)(q11.222),del(Y)(q11.222)[5]. Ultrasound examination suggested hypospadia, which was confirmed after elective abortion. Combined the results of genetic testing and phenotypic analysis, the fetus was ultimately diagnosed with DSDs.
CONCLUSION
This study has applied a variety of genetic techniques and ultrasonography to diagnose a fetus with DSDs with a complex karyotype.

Telephone follow-up is one of the important ways to follow up patients. High-quality follow-up can benefit both doctors and patients. However, clinical research-related follow-up is often faced with problems such as time-consuming, laborious and poor patient compliance. The authors belong to a team that has been committed to the study of patient-reported outcomes for a long time. The team has carried out long-term follow-up of symptoms, daily function and postoperative complications of more than 1 000 patients after lung cancer surgery, and accumulated certain experience. In this paper, the experience of telephone follow-up was summarized and discussed with relevant literatures from the aspects of clarifying the purpose of clinical research follow-up, understanding the needs of patients in follow-up, and using follow-up skills.
