ObjectiveTo investigate the mechanism by which Feixin decoction treats hypoxic pulmonary hypertension （HPH） by regulating the peroxisome proliferator-activated receptor gamma （PPARγ）/nuclear factor-kappa B （NF-κB）/NOD-like receptor pyrin domain containing 3 （NLRP3） signaling pathway. MethodsForty-eight male SD rats were randomly allocated into normal， hypoxia， and low-， medium- and high-dose （5.85， 11.7， 23.4 g·kg^-1， respectively） Feixin decoction groups， with 8 rats in each group. Except the normal group， the remaining five groups were placed in a hypoxia chamber with an oxygen concentration of （10.0±0.5）% for 8 h per day， 28 days， and administrated with corresponding drugs during the modeling process. After 4 weeks of treatment， echocardiographic parameters ［pulmonary artery acceleration time （PAT）， pulmonary artery ejection time （PET）， right ventricular anterior wall thickness （RVAWd）， and tricuspid annular plane systolic excursion （TAPSE）］ were measured for each group. The right ventricular systolic pressure （RVSP） was measured by the right heart catheterization method， and the right ventricular hypertrophy index （RVHI） was calculated by weighing the heart. The pathological changes in pulmonary arterioles were observed by hematoxylin-eosin staining. The co-localization of α-smooth muscle actin （α-SMA） with NLRP3， N-terminal gasdermin D （N-GSDMD）， and cysteinyl aspartate-specific proteinase-1 （Caspase-1） in pulmonary arteries was detected by immunofluorescence. The protein levels of PPARγ， NF-κB， NLRP3， apoptosis-associated speck-like protein containing a CARD （ASC）， N-GSDMD， interleukin-1β （IL-1β）， interleukin-18（IL-18）， and cleaved Caspase-1 in the lung tissue was determined by Western blot. The ultrastructural changes in pulmonary artery smooth muscle cells （PASMCs） were observed by transmission electron microscopy. ResultsCompared with the normal group， the hypoxia group showed increased RVSP and RVHI （P<0.01）， decreased right heart function （P<0.01）， increased pulmonary vascular remodeling （P<0.01）， increased co-localization of α-SMA with NLRP3， N-GSDMD， and Caspase-1 in pulmonary arterioles （P<0.01）， up-regulated protein levels of NF-κB， NLRP3， ASC， N-GSDMD， IL-1β， IL-18， and cleaved Caspase-1 in the lung tissue （P<0.05， P<0.01）， a down-regulated protein level of PPARγ （P<0.05， P<0.01）， and pyroptosis in PASMCs. Compared with the hypoxia group， Feixin decoction reduced RVSP and RVHI， improved the right heart function and ameliorated pulmonary vascular remodeling （P<0.05， P<0.01）， decreased the co-localization of α-SMA with NLRP3， N-GSDMD， and Caspase-1 （P<0.05， P<0.01）， down-regulated the protein levels of NF-κB， NLRP3， ASC， N-GSDMD， IL-1β， IL-18， and cleaved Caspase-1 in the lung tissue （P<0.05， P<0.01）， up-regulated the protein level of PPARγ （P<0.05， P<0.01）， and alleviated pyroptosis in PASMCs. ConclusionFeixin decoction can ameliorate pulmonary vascular remodeling and right heart dysfunction in chronically induced HPH rats by regulating pyroptosis in PASMCs through the PPARγ/NF-κB/NLRP3 pathway.

OBJECTIVE: To investigate the effectiveness of the suture anchor technique without knots for reconstruction of the anterior talofibular ligament (ATFL) combined with the reinforcement of the inferior extensor retinaculum in treating chronic lateral ankle instability (CLAI). METHODS: The clinical data of 31 patients with CLAI who were admitted between August 2017 and December 2023 and met the selection criteria were retrospectively analyzed. There were 18 males and 13 females, with an age range from 20 to 48 years (mean, 34.6 years). All patients had a history of repeated ankle sprain, with a disease duration of 6-18 months (mean, 9.65 months). The anterior drawer test and inversion stress test were positive, and tenderness was present in the ligament area. Stress X-ray films of the ankle joint showed a talar tilt angle of (10.00±2.78)° and an anterior talar displacement of (9.48±1.96) mm on the affected side. MRI revealed discontinuity, tortuosity, or disappearance of the ATFL structure. Preoperatively, the visual analogue scale (VAS) score was 5.2±2.1, and the American Orthopaedic Foot and Ankle Society (AOFAS) score was 62.9±7.1. All patients underwent arthroscopic debridement of the ankle joint followed by reconstruction of the ATFL using the suture anchor technique without knots combined with reinforcement of the inferior extensor retinaculum. Postoperatively, pain and function were assessed using the VAS and AOFAS scores. Stress X-ray films were taken to measure the talar tilt angle and anterior talar displacement to evaluate changes in ankle joint stability. Patient satisfaction was assessed according to the Insall criteria. RESULTS: All 31 surgeries were successfully completed. One case had wound exudation, while the remaining surgical incisions healed by first intention. Two cases experienced numbness on the lateral aspect of the foot, which disappeared within 1 month after operation. All patients were followed up 15-84 months (mean, 47.2 months). No complication such as anchor loosening, recurrent lateral ankle instability, superficial peroneal nerve injury, rejection reaction, or wound infection occurred postoperatively. The anterior drawer test and inversion stress test were negative at 3 months after operation. Stress X-ray films taken at 3 months after operation showed the talar tilt angle of (2.86±1.72)° and the anterior talar displacement of (2.97±1.32) mm, both of which were significantly different from the preoperative values ( t=12.218, P<0.001; t=15.367, P<0.001). At last follow-up, 2 patients had ankle swelling after exercise, which resolved spontaneously with rest; all 31 patients returned to their pre-injury level of sports or had no significant discomfort in daily activities. At last follow-up, 25 patients were pain-free, 4 had mild pain after exercise, and 2 had mild pain after walking more than 2 000 meters. The VAS score was 0.8±0.9 and the AOFAS score was 91.6±4.1, both of which were significantly different from the preoperative scores ( t=10.851, P<0.001; t=-19.514, P<0.001). According to the Insall criteria, 24 patients were rated as excellent, 4 as good, and 3 as fair, with a satisfaction rate of 90.3%. CONCLUSION The suture anchor technique without knots for reconstruction of the ATFL combined with reinforcement of the inferior extensor retinaculum provides satisfactory short- and mid-term effectiveness in treating CLAI.

Addressing the enduring challenge of evaluating traditional Chinese medicines (TCMs), the integrated evidence chain-based effectiveness evaluation of TCMs (Eff-iEC) has emerged. This paper explored its capacity through a demonstration study that evaluated the effectiveness evidence of six commonly used anti-hepatic fibrosis Chinese patent medicines (CPMs), including Biejiajian Pill (BP), Dahuang Zhechong Pill (DZP), Biejia Ruangan Compound (BRC), Fuzheng Huayu Capsule (FHC), Anluo Huaxian Pill (AHP), and Heluo Shugan Capsule (HSC), using both Eff-iEC and the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system. The recognition of these CPMs within the TCM academic community was also assessed through their inclusion in relevant medical documents. Results showed that the evidence of BRC and FHC received higher assessments in both Eff-iEC and GRADE system, while the assessments for others varied. Analysis of community recognition revealed that Eff-iEC more accurately reflects the clinical value of these CPMs, exhibiting superior evaluative capabilities. By breaking through the conventional pattern of TCMs effectiveness evaluation, Eff-iEC offers a novel epistemology that better aligns with the clinical realities and reasoning of TCMs, providing a coherent methodology for clinical decision-making, new drug evaluations, and health policy formulation.

Objective : To explore the differences in oxidative stress levels between patients with and without non-suicidal self-injury(NSSI) behavior in depressive disorders, and their correlation with depressive symptoms, disease duration, and self-injury frequency. Methods : A total of 95 subjects were included in the study, including 65 patients with depression(patient group). They were divided into NSSI subgroup(31 cases) and Non-NSSI subgroup(34 cases) based on whether they had NSSI. 30 healthy control group cases(HC). Enzyme linked immunosorbent assay(ELISA) was used to detect the levels of superoxide dismutase(SOD), catalase(CAT), malondialdehyde(MDA), glutathione peroxidase(GPX), and oxidized low-density lipoprotein(OxLDL) in the peripheral blood of the subjects. The Hamilton depression rating scale(HAMD-17) was used to assess the patient′s condition, and the Ottawa self-injury inventory(OSI) was used to quantitatively evaluate the self-injury frequency of NSSI group patients. Results : The levels of SOD, CAT,MDA,GPX and OxLDL in the patient group were significantly higher than those in the control group(P<0.05). The levels of SOD, CAT, MDA,GPX and OxLDL in the NSSI subgroup were significantly higher than those in the Non-NSSI subgroup and the control group(P<0.05).The duration of the NSSI subgroup was positively correlated with the levels of SOD,CAT,and MDA(r=0.504,P=0.004; r=0.568,P=0.001; r=0.404,P=0.024),and the HAMD-17 score was positively correlated with the levels of SOD,CAT,and MDA(r=0.573,P=0.001; r=0.577,P=0.001; r=0.477,P=0.007). The frequency of self-injury was positively correlated with the levels of SOD and MDA(r=0.558,P=0.001; r=0.494,P=0.005). Conclusion The OS level of patients with depression is significantly higher than that of the healthy population,and among them,patients with depression accompanied by NSSI have a more significant increase in oxidative stress level. Elevated levels of OS may affect the severity,duration,and frequency of self-injurious behavior in patients with depression accompanied by NSSI.

Objective:To examine the feasibility and clinical effect of all-inside endoscopic procedure through two portals combined with double-hemisection Achilles tendon lengthening for Achilles tendon contracture.Methods:This is a retrospective case series study. From February 2021 to February 2023, the clinical data of 24 patients (30 feet) with Achilles tendon contracture treated with all-inside endoscopic procedure through two portals combined with double-hemisection Achilles tendon lengthening were analyzed retrospectively. There were 10 males and 14 females, aged (32.8±16.1) years (range: 9 to 62 years). There were 8 cases of left side only, 10 cases of right side only and 6 cases of bilateral. There were 14 cases (16 feet) of foot varus, 4 cases (6 feet) of foot valgus, and 6 cases (8 feet) without deformity. All patients underwent all-inside endoscopic procedure through two portals combined with double-hemisection Achilles tendon lengthening. The surgical effects were evaluated using the maximum dorsal extension angle of ankle joint in knee extension position, the visual analogue scale (VAS) of pain, the American Orthopedic Foot and Ankle Society ankle-hindfoot score(AOFAS-AH). Paired sample t test was used to compare the scores before and after operation.Results:All patients successfully completed the operation, and the operation time of Achilles tendon lengthening was (22.0±5.7)minutes (range: 15 to 35 minutes) and the intraoperative blood loss was (6.5±2.7)ml (range: 2 to 15 ml). All patients primarily healing without any complications such as sural nerve injury, Achilles tendon rupture, important blood vessel injury, and obvious decrease of lift heel strength of achilles tendon. All 24 patients were followed up for (17.2±4.5) months (range: 12 to 28 months). One patient suffered from lift heel′s weakness in one foot after operation, and recovered after repeated lift heel functional exercises. The ankle dorsiflexion function of two patients with calf triceps spasm were not improved after operation, and it was obviously improved after botulinum toxin injection. At the last follow-up, the maximum dorsal extension angle of ankle joint in knee extension position increased from -9.2°±7.6°(range:-25° to 5°) preoperatively to 14.5°±7.0°(range:0° to 28°)( t=24.83, P<0.01); the VAS score was reduced from (4.5±1.7) points (range:1 to 8 points) preoperatively to (1.5±0.9) points (range:0 to 3 points) ( t=9.53, P<0.01), the AOFAS-AH was increased from (60.5±11.4)points (range:38 to 85 points) to (90.8±5.4) points (range:80-100 points)( t=14.21, P<0.01). Conclusions:All-inside endoscopic procedure through two portals combined with double-hemisection Achilles tendon lengthening for Achilles tendon contracture not only provides Achilles tendon lengthening, but also avoids complications such as Achilles tendon rupture and sural nerve injury. It is an effective method for the treatment of Achilles tendon contracture.

[Objective]To summarize the theoretical viewpoints and therapeutic applications of Professor FU Wenbin in the treatment of persistent somatoform pain disorder(PSPD).[Methods]By following the teacher's clinical evidence,organizing medical cases and combining with literature search,this article analyzed and summarized Professor FU's identification ideas and clinical experience in treating PSPD by using the integrated acupuncture model with a medical case attached.[Results]Professor FU believes that the disease is the result of the joint influence of emotional factors and body meridians Qi and blood lesions,which belongs to"pain caused by Qi injury".The diagnosis and treatment concepts of"soothing the liver"and"regulating the mind"are also emphasized,as well as the combination of"acupuncture at the top priority,followed by moxibustion and consolidation at the end"integration of acupuncture and moxibustion mode of treatment.This article cites the case of a female patient with long-term lower abdominal distension and pain to detail the application of therapies.The pain was the main symptom associated with emotional effects,mostly due to the meridian Qi and blood stagnation,so it took acupuncture for"soothing the liver and regulating the mind"as the key rule of treatment.In the operation of acupuncture,Professor FU suggested the need to pay attention to patient's mind,to enter and exit the needle slowly,and to cross-reference the pulse with the symptoms.The selection of acupuncture points emphasized the elevation and harmonization of Qi and blood.Acupuncture,moxibustion,bloodletting and intradermal needle embedding and other traditional Chinese medicine special therapy treatments were used to treat PSPD.[Conclusion]Professor FU's treatment of PSPD focuses on"soothing the liver and regulating the mind",treating the mind and body together,and using acupuncture and moxibustion to achieve good clinical efficacy.The experience can also provide ideas for the treatment of psychosomatic diseases with acupuncture and moxibustion,which is worthwhile to learn from in the clinic.

Objective To monitor heart-related parameters of hypoxic pulmonary hypertension(PH)mouse models induced by hypoxia alone and hypoxia combined with vascular endothelial growth factor receptor inhibitor SU5416 using echocardiography,and to construct the prediction equation of right ventricular systolic pressure(RVSP).Twenty-four C57BL/6J male mice were randomly divided into simple hypoxia group(group A),hypoxia combined with SU5416 group(group B),control group(group C),each group 8 mice.Hypoxic PH models were constructed with hypoxia alone and hypoxia combined with SU5416 in group A and group B,respectively.Echocardiography was performed before and during modeling(2,3,4 weeks after interventions),and the relevant parameters were obtained.RVSP was measured using right heart catheterization after the last echocardiography.The changes of ultrasonic parameters were observed,the correlations of ultrasonic parameters 4 weeks after intervention with RVSP were observed,and linear equations for predicting RVSP were established.Results With time going,during modeling,pulmonary artery diameter(PAD),PAD/aorta diameter(AOD)and right ventricle anterior wall thickness(RVAWT)increased,while heart rate,pulmonary artery acceleration time(PAAT),PAAT/pulmonary artery ejection time(PAET)and tricuspid annular plane systolic excursion(TAPSE)decreased in group A and B(all P＜0.05).Three and 4 weeks after interventions,PAET,PAAT/PAET and TAPSE in group B decreased compared with those in group A(all P＜0.05).Four weeks after interventions,RVSP in group A and B were highly correlated with PAD/AOD,RVAWT,PAAT,PAAT/PAET and TAPSE(all P＜0.05).The linear regression equations of PAAT/PAET and TAPSE for predicting RVSP in simple hypoxic PH mice models included RVSP=-161.7 ×(PAAT/PAET)+63.85,as well as RVSP=-36.53 ×TAPSE+71.55,while of predicting RVSP in hypoxia combined with VEGFR-2 inhibitor PH mouse models were as follows:RVSP=-266.4 ×(PAAT/PAET)+91.59,RVSP=-69.14 × TAPSE+116.5.Conclusion Four weeks after inerventions,the phenotypes of hypoxic PH mouse models induced by hypoxia alone and hypoxia combined with SU5416 became obvious.Prediction equations of RVSP established based on PAAT/PAET and TAPSE obtained with echocardiography could provide references for relevant research.

Objective:To analyze the clinical characteristics and risk factors of asparaginase-associated pancreatitis(AAP)in children with acute lymphoblastic leukemia(ALL),and to investigate the impact of AAP on their prognosis following re-exposure to asparaginase(ASP).Methods:Clinical children data with ALL at Tongji Hospital,Tongji Medical College of Huazhong University of Science and Technology between January 2015 and June 2020 were collected to analyze the clinical features of AAP.Logistic regression was used to identify risk factors for AAP.Prognostic analysis was performed using the Log-rank test and Kaplan-Meier survival curves.Results:Overall,252 children with ALL were included,among whom 23(9.1%)developed AAP.Most AAP cases(82.6%)occurred during remission induction,with a medi-an time from the last ASP to AAP of 12 d.Elevated total cholesterol(≥3.5 mmol/L)at initial diagnosis was identified as an independent risk factor.Six children(26.1%)were re-exposed to ASP,leading to recurrent pancreatitis in 3 cases.The 5-year overall survival(OS)was signific-antly lower in the AAP group(78.3%±8.6%)compared to the non-AAP group(90.3%±2.2%)(P<0.05).Similarly,children who discontinued ASP due to AAP had a 5-year OS of 77.8%±9.8%,significantly lower than the control group(90.1%±2.1%).Conclusions:AAP typically oc-curred within 12 d of the last ASP administration and was associated with poorer 5-year OS.Re-exposure to ASP posed a risk of recurrent AAP;however,completing the ASP chemotherapy regimen may be crucial for improving prognosis.

Pulmonary hypertension(PH)is a progressive pulmonary vascular disease that can lead to right heart failure and death.In recent years,the incidence of PH has been increasing year by year and there is a lack of effective treatment.TCM can play an important synergistic role in the treatment of PH.Pulmonary vascular remodeling is a core pathological feature of PH,which is closely related to the physiological structure and pathological changes of the collaterals.Based on the collateral disease theory,this article described the key pathogenesis of PH in TCM and Western medicine,including the lesions of the pulmonary and cardiovascular complexes and pulmonary vascular remodeling,analyzed the physiology of the"collateral-vessel"in PH,sorting out the pathological correlation,and explored TCM targeting pulmonary vascular remodeling in the identification and treatment of PH,so as to provide a new way of thinking for the clinical treatment of PH.
