Early identification of adolescent depression requires objective biomarkers. This study investigated the functional near-infrared spectroscopy (fNIRS) activation patterns and mismatch negativity (MMN) characteristics in adolescents with first-episode mild-to-moderate depression. We enrolled 33 patients and 33 matched healthy controls, measuring oxyhemoglobin (Oxy-Hb) concentration in the frontal cortex during verbal fluency tasks via fNIRS, and recording MMN latency/amplitude at Fz/Cz electrodes using event-related potentials (ERP). Compared with healthy controls, the depression group showed significantly prolonged MMN latency [Fz: (227.88 ± 31.08) ms vs. (208.70 ± 25.35) ms, P < 0.01; Cz: (223.73 ± 29.03) ms vs. (204.18 ± 22.43) ms, P < 0.01], and obviously reduced Fz amplitude [(2.42 ± 2.18) μV vs. (5.65 ± 5.59) μV, P = 0.03]. A significant positive correlation was observed between MMN latencies at Fz and Cz electrodes ( P < 0.01). Oxy-Hb in left frontopolar prefrontal channels (CH15/17) was significantly decreased in patient group ( P < 0.05). Our findings suggest that adolescents with depression exhibit hypofunction in the left prefrontal cortex and impaired automatic sensory processing. The combined application of fNIRS and ERP techniques may provide an objective basis for early clinical identification.

Objective:To investigate the safety of early antiplatelet therapy for non-cardioembolic mild stroke patients with thrombocytopenia.Methods:Data of acute ischemic stroke patients with baseline National Institutes of Health Stroke Scale(NIHSS)score≤3 and a platelet count<100×109/L were obtained from a multicenter register.Those who required anticoagulation or had other contraindications to antiplatelet therapy were excluded.Short-term safety outcomes were in-hospital bleeding events,while the long-term safety outcome was a 1-year all-cause death.The short-term neurological outcomes were evaluated by modified Rankin scale(mRS)score at discharge.Results:A total of 1868 non-cardioembolic mild stroke patients with thrombocytopenia were enrolled.Multivariate regression analyses showed that mono-antiplatelet therapy significantly increased the proportion of mRS score of 0-1 at discharge(OR=1.657,95%CI:1.253-2.192,P<0.01)and did not increase the risk of intracranial hemorrhage(OR=2.359,95%CI:0.301-18.503,P>0.05),compared with those without antiplatelet therapy.However,dual-antiplatelet therapy did not bring more neurological benefits(OR=0.923,95%CI:0.690-1.234,P>0.05),but increased the risk of gastrointestinal bleeding(OR= 2.837,95%CI:1.311-6.136,P<0.01)compared with those with mono-antiplatelet therapy.For patients with platelet counts≤75×109/L and>90×109/L,antiplatelet therapy significantly improved neurological functional outcomes(both P<0.05).For those with platelet counts(>75-90)×109/L,antiplatelet therapy resulted in a significant improvement of 1-year survival(P<0.05).For patients even with concurrent coagulation abnormalities,mono-antiplatelet therapy did not increase the risk of various types of bleeding(all P>0.05)but improved neurological functional outcomes(all P<0.01).There was no significant difference in the occurrence of bleeding events,1-year all-cause mortality risk,and neurological functional outcomes between aspirin and clopidogrel(all P>0.05).Conclusions:For non-cardioembolic mild stroke patients with thrombocytopenia,antiplatelet therapy remains a reasonable choice.Mono-antiplatelet therapy has the same efficiency as dual-antiplatelet therapy in neurological outcome improvement with lower risk of gastrointestinal bleeding.

Objective To investigate the risk factors of internal fixation failure in proximal femoral nail antirotation (PFNA) for treating intertrochanteric fracture.Methods The imageological data of 179 patients with intertrochanteric fracture receiving PFNA internal fixation were analyzed retrospectively.The univariate analysis was adopted to analyze the influence of the gender,degree of osteoporosis,AO/OTA fracture type,top apex distance (TAD),postoperative coxa vara,lateral wall state,fracture reduction situation and screw blade position on the internal fixation failure.The logistic regression model was constructed.The risk factors of internal fixation failure were analyzed.Results Among 179 patients,the internal fixation failure occurred in 16 cases.The univariate analysis showed the AO/OTA fracture type,TAD,postoperative coxa vara,lateral wall state,fracture reduction effect and screw blade location were related with the internal fixation failure (P<0.05).The logistic regression analysis prompted that postoperative coxa vara (OR=6.97,95％CI:2.24-21.68,P=0.001) and the lateral wall breakage (OR=3.08,95％CI:1.03-9.22,P=0.045) were the risk factors of internal fixation failure in femoral intertrochanteric fracture.Conclusion Coxa vara and lateral wall breakage are the risk factors of internal fixation failure in PENA for treating femoral intertrochanteric fracture,and the operation reduction should avoid the coxa vara appearance.

Objective To explore the application value of suture traction suspension method in endoscopic thyroid cancer radical surgery through the anterior chest approach.Methods A retrospective analysis was made on 108 cases of papillary thyroid cancer from January 2020 to December 2022,who underwent unilateral lobectomy and ipsilateral central lymph node dissection through anterior chest approach.After May 2021,the suture traction and suspension method was gradually carried out by using 2-0 polypropylene suture to suspend the muscles,trachea,and thyroid gland lobes.There were 51 cases in the suture traction suspension group and 57 cases in the conventional endoscopic group.The intraoperative and postoperative indicators were compared between the two groups.Results The surgery was successfully completed in both groups.As compared to the conventional endoscopic group,the suture traction suspension group had shorter surgical time for thyroidectomy[(35.3±7.3)min vs.(43.4±8.4)min,t =-5.342,P<0.001],shorter surgical time for central lymph node dissection[(20.1±3.5)min vs.(27.7±4.9)min,t =-9.271,P<0.001],less intraoperative bleeding[10(5-15)ml vs.15(5-30)ml,Z =-6.250,P<0.001],and more central lymph nodes dissected[8(3-13)vs.6(4-10),Z =3.272,P =0.001].There were fewer cases of transient recurrent laryngeal nerve injury after surgery in the suture traction suspension group,but no statistical significance was noted(1 case vs.8 cases,χ2 =3.678,P =0.055).There were no statistically significant differences in postoperative hospitalization time,postoperative lymph leakage,parathyroid gland detection in postoperative specimens,postoperative hypoparathyroidism,postoperative pain score,and postoperative cosmetic effect score between the two groups(P>0.05).Conclusion Suture traction suspension method can shorten surgical time,reduce intraoperative bleeding,reduce the occurrence of recurrent laryngeal nerve injury,and increase the number of central lymph node dissection.

Objective:To investigate the value of 3D CT reconstruction in diagnosis of chronic lateral ankle instability (CLAI) combined with syndesmotic diastasis (SD).Methods:A retrospective study was conducted to analyze the clinical data of 160 patients with CLAI who had been examined by arthroscopy from January 2018 to September 2022 at Department of Foot and Ankle Surgery, Wuhan Fourth Hospital. There were 64 males and 96 females with an age of (39.8±12.6) years. Eighty-one left and 79 right feet were affected; the time from injury to surgery was (27.3±11.6) months. The patients were divided into a widened interval group and a normal interval group according to the syndesmotic width measured, with 2 mm as a critical value. After preoperative 3D CT reconstruction, the differences in anterior tibiofibular distance, posterior tibiofibular distance, the narrowest tibiofibular distance, fibular translation, fibular rotation, and syndesmotic area (SA) were compared between the 2 groups. Univariate and multivariate analyses were performed successively to identify the risk factors. The receiver operating characteristic (ROC) curve was used to identify the best predictive factor and critical value. According to the findings of previous research, the above analyses were repeated to determine the best predictive factor and critical value respectively in the sex subgroup, fibular morphology subgroup and incisura feature subgroup.Results:The binary logistic regression showed that SA was a risk factor for CLAI combined with SD ( OR=1.196, 95% CI: 1.122 to 1.275, P < 0.001). The ROC curve revealed an area under curve of 0.847 and the difference critical value of 22.06 mm 2 that indicated a sensitivity of 80.4% and a specificity of 78.9%, respectively. Subgroup analyses showed that SA was suitable for male and female patients and patients with different fibular morphologies and incisura features but the difference critical values were different. Conclusion:In 3D CT reconstruction, measurement of SA may help the diagnosis of CLAI combined with SD.

Background and Aims:Recurrent laryngeal nerve (RLN) injury during endoscopic thyroid cancer radical surgery significantly affects postoperative recovery and quality of life. Avoiding RLN injury has always been a key concern during thyroid surgeries. Choosing an appropriate and safe approach to expose the RLN in endoscopic thyroid cancer surgery may reduce the risk of RLN injury. However,the optimal approach for RLN exposure in endoscopic thyroid cancer radical surgery through the anterior chest approach remains inconclusive. This study was performed to compare the surgical outcomes of using the medial and lateral approaches to expose the RLN in endoscopic thyroid cancer surgery through the anterior chest approach,so as to provide reference for clinical practice.Methods:The clinical data of 85 patients who underwent endoscopic thyroid cancer radical surgery (ipsilateral lobectomy and ipsilateral central lymph node dissection) via the anterior chest approach at Zhuzhou Hospital Affiliated to Xiangya Medical College,Central South University,from January 2020 to January 2023 were retrospectively analyzed. Among the patients,medial approach was used in 45 cases (medial approach group) and lateral approach was used for RLN exposure in 40 cases (lateral approach group). The main clinical variables were compared between the two groups. Results:No statistically significant differences were found in baseline data between the two groups (all P>0.05). Both groups successfully completed endoscopic thyroidectomy via the anterior chest approach with complete RLN exposure at the main trunk and its entry into the larynx. The RLN exposure time and endoscopic surgery time in the medial approach group were significantly shorter than those in the lateral approach group (both P<0.05). Intraoperative blood loss was significantly less in the medial approach group compared to the lateral approach group (P<0.05). There were no cases of transient RLN injury in the medial approach group,whereas 5 cases of transient RLN injury occurred in the lateral approach group,with a statistically significant difference (P<0.05). The medial approach group had fewer cases of thyroid tissue residue at the Berry's ligament and transient hypoparathyroidism than the lateral approach group,but the differences were not statistically significant (both P>0.05). There were no statistically significant differences between the two groups in postoperative hospital stay or postoperative drainage volume (both P>0.05). Conclusion:The medial approach for RLN exposure in endoscopic thyroid cancer surgery is safe and feasible. Compared to the lateral approach,it allows faster RLN exposure,effectively reduces the risk of transient RLN injury,decreases intraoperative blood loss and operative time,and may also reduce the incidence of transient hypoparathyroidism and thyroid tissue residue to some extent.

Female pelvic organ prolapse (POP) is caused by damage or loss of pelvic floor support, resulting in displacement of the pelvic organs, which leads to abnormalities in the position and function of the organs, mainly due to damage to the pelvic floor mechanical support structures caused by transvaginal birth, loss of elasticity of the pelvic floor mechanical support structures in old women, and loss of the ability to maintain the pelvic floor. The key to POP surgery is the repair of the apical vagina, but treatment based on this theory has failed to achieve satisfactory clinical outcomes. This article will analyze the common procedures of apical suspension in the treatment of mid-pelvic prolapse from the perspective of pelvic floor morphological features and pelvic floor biomechanics axially.

Objective:intrahepatic portocaval shunt (TIPS) in the treatment of hepatic sinusoidal obstruction syndrome (HSOS).Methods:A retrospective analysis was performed on 27 patients with HSOS who were treated with TIPS in our center from July 2018 to July 2020. The changes of portal vein pressure (PVP), portal vein pressure gradient (PPG) and liver function were observed, so as to evaluate the efficacy. Paired t test was adopted to evaluate the quantitative parameters, while χ2 test was used to analyze qualitative parameters, with P < 0.05 as statistical difference. Results:PVP decreased from (4.41 ± 0.18) kPa before shunt to (2.69 ± 0.11) kPa after shunt ( t = 82.41, P < 0.001), PPG decreased from (3.23 ± 0.18) kPa before shunt to (1.46 ± 0.23) kPa after shunt ( t = 32.41, P < 0.001). The liver function improved significantly after operation. After 24 months of follow-up, 3 patients developed stent restenosis and recanalized after balloon dilation. Three patients developed hepatic encephalopathy, which was improved after drug treatment. One patient underwent liver transplantation due to liver failure. Conclusion:TIPS is effective in the treatment of HSOS in the short and medium term, and can provide time for liver transplantation patients to wait for liver source.

Schizophrenia is a serious mental disease. The diagnosis of schizophrenia so far relies heavily on subjective evidence, including self-reported experiences by patients, manifestations described by relatives, and abnormal behaviors assessed by psychiatrists. The diagnosis, monitoring of the disease progression and therapy efficacy assessment are challenging due to the lack of established laboratory biomarkers. Based on the current literature, clinical consensus, guidelines, and expert recommendations, this review highlighted evidence-based potential laboratory biomarkers for the diagnosis of schizophrenia, including genetic biomarkers, neurotransmitters, neurodevelopmental-related proteins, and intestinal flora, and discussed the potential future directions for the application of these biomarkers in this field, aiming to provide an objective basis for the use of these biomarkers in the early and accurate diagnosis, treatment, and prognosis and rehabilitation assessment of schizophrenia.
