Mitochondrial quality control （MQC） homeostasis serves as a fundamental mechanism in maintaining the mitochondrial structure and function. Dysregulation of MQC contributes to the progression of acute ischemic stroke （AIS） through multiple pathways including disturbances in energy metabolism， increased oxidative stress， and imbalances in mitochondrial fusion and fission. Drawing upon the traditional Chinese medicine （TCM） theory of the kidney governing Yin and Yang， this study innovatively proposes an integrative model of "Yin-Yang dynamic balance-MQC homeostasis" to elucidate the underlying pathophysiological mechanisms. Specifically， kidney Yang deficiency and decline result in reduced driving force， thereby inhibiting mitochondrial fusion. This leads to decreased efficiency of oxidative phosphorylation and impaired adenosine triphosphate （ATP） production. Conversely， when kidney Yin is dysfunctional and excessive phlegm-blood stasis accumulates， mitochondrial fission becomes hyperactive， causing rapid accumulation of reactive oxygen species （ROS） and intensified oxidative stress. The interplay between these two pathological states culminates in the central TCM pathogenesis—Yin-Yang imbalance and disordered Qi and blood-of AIS. To address this pathogenesis， a therapeutic strategy is proposed： tonifying the kidney as the primary intervention to restore MQC homeostasis， supplemented by resolving phlegm and removing blood stasis to interrupt the deleterious cycle of cerebral vascular damage. This work integrates the holistic perspective of TCM with contemporary molecular insights， offering precise intervention targets along the "kidney-mitochondria axis" for the prevention and treatment of AIS， while establishing a novel integrative paradigm for stroke management that bridges traditional and modern medicine. Future research should focus on elucidating the molecular mechanisms through which TCM regulates MQC in AIS and integrating classical TCM theories with evidence-based medicine to facilitate the translation of theoretical insights into clinical applications.

Objective:To explore the intervention effects of the skill training for parents with autism child (STPAC) on toddlers with autism spectrum disorder (ASD).Methods:A multicenter non-randomized concurrent controlled study design was conducted. Thirty children with ASD aged 15-30 months, first diagnosed at the Children′s Hospital of Fudan University, the First Hospital of Jilin University, and Chengdu Women′s and Children′s Central Hospital from 2019 to 2020, were enrolled in the STPAC group. Thirty children with ASD who visited the same hospitals during the same period but refused the STPAC intervention were selected as the control group. The STPAC group received an 8-week intervention (3 h/week) followed by quarterly follow-ups for 1 year, while the control group voluntarily chose community-based routine interventions. The Griffiths development scales-Chinese (GDS-C) was used to assess the developmental levels, and the communication and symbolic behavior scales developmental profile infant-toddler checklist (CSBS-DP-ITC) was completed by the primary caregivers to evaluate social, language and symbolic behavior. The independent samples t-tests or Mann-Whitney U tests, etc.was used for inter-group comparison. The paired t-tests or Wilcoxon signed-rank tests, etc. was used for inter-group pre-post intervention comparison. Results:The STPAC group included 30 children (22 males and 8 females, aged (23.9±2.2) months), and the control group included 30 children (20 males and 10 females, aged (24.2±2.6) months). Before the intervention, there were no statistically differences in GDS-C development quotient (DQ) and CSBS-DP-ITC scores between groups (all P>0.05). After 1-year intervention, GDS-C DQ in personal-social, hearing-language, hand-eye coordination, performance domains of STPAC group and GDS-C DQ in personal-social, hearing-language domains of control group were all increased (all P<0.01). After 1-year intervention, CSBS-DP-ITC scores of both groups were all improved in socia, language, symbolic behavior, and total scores (all P<0.001). GDS-C DQ changes before and after 1 year of intervention in hearing-language, hand-eye coordination, performance domains of the STPAC group were all higher the those of control group (34(15, 48 vs. 10(-4, 39), 11±20 vs. -1±19, 23±25 vs. 8±22, all P<0.05). CSBS-DP-ITC scores changes before and after 1 year of intervention in social and total scores of the STPAC group were both higher the those of control group (10(5, 30) vs. 3(1, 7), 26±17 vs. 11±8, both P<0.001). Conclusion:Compared with the community routine interventions, the STPAC better improves the language, hand-eye coordination, visual-spatial, social communication, and play skills in ASD toddlers.

Objective:To investigate the effect of visceral obesity on the short-term curative effect of Da Vinci robotic-assisted radical resec-tion for rectal cancers.Methods:Clinical and pathological data of patients with rectal cancer undergoing Da Vinci robotic-assisted surgery,admitted to People's Hospital of Zhengzhou University and Cancer Hospital of Zhengzhou University from November 2019 to June 2022 were retrospectively analyzed.Visceral fat area(VFA)≥100 cm2 was used as the standard to define visceral obesity.Patients were categorized in-to visceral and non-visceral obesity groups.The short-term efficacy of the two groups was evaluated,and the influencing factors of post-operative complications were analyzed using univariate and multivariate Logistic regression.Results:Among a total of 169 patients,93 were included in the visceral obesity group and 76 in the non-visceral obesity group.There was no significant difference in the baseline data between the two groups(P>0.05).There was no conversion to laparotomy in the non-visceral obesity group,and the conversion rate was 1.1%(1/93)in the visceral obesity group.The second operation rate was 2.2%(2/93)in the visceral obesity group and 1.3%(1/76)in the non-visceral obesity group with no statistical difference between the two groups.There were no significant differences in the operation dur-ation,intraoperative blood loss,number of lymph node dissections,and total postoperative complication rate between the two groups(P>0.05).Multivariate Logistic regression analysis revealed that an NRS≥3 independently contributed as a risk factor for postoperative com-plications(OR=3.190,95%CI:1.240-8.210,P=0.016).Conclusions:An NRS≥3 is an independent risk factor for complications post-robotic rad-ical rectal cancer surgery.The robotic surgical platform can overcome obesity-related limitations and is equally safe and effective for pa-tients with visceral obesity presenting with rectal cancer.

Objective:To compare the efficacy, safety, and influencing factors among children with hepatitis B virus e antigen (HBeAg)-positive chronic hepatitis B (CHB) who received short-term therapy with pegylated interferon alfa-2a (Peg-IFNα-2a) or continuous therapy with entecavir (ETV).Methods:Quantitative data were compared using analysis of variance to compare the differences between groups. Enumeration data were compared by χ2 test (or Fisher's exact test). Univariate and multivariate logistic regressions were used to analyze the influencing factors. Results:Peg-IFNα-2a, ETV, and untreated group had HBsAg clearance rates of 46.2%, 5.3%, and 0 after 52 weeks of therapy, respectively. HBsAg clearance in the patients' group with Peg-IFNα-2a and ETV was all accompanied by anti-HBS positive conversion, and the difference was statistically significant ( χ2=13.616, P=0.001). Peg-IFNα-2a group was followed-up for 104 weeks. Peg-IFNα-2a, ETV, and the untreated group had HBsAg clearance rates of 46.2%, 10.5%, and 0%, respectively, and the differences were statistically significant ( χ2=11.056, P=0.004). Only one of the two children with HBsAg clearance in the ETV group had achieved anti-HBs antibodies, and the difference was statistically significant ( χ2=13.616, P=0.001). Univariate and multivariate logistic regression analysis showed that HBsAg clearance was associated with age and antiviral therapy. During treatment, adverse events such as fever ( n=4, 30.8%), rash ( n=4, 30.8%), fatigue ( n=1, 7.7%), leukopenia ( n=7, 53.8%), arthritis ( n=1, 7.7%), and alopecia ( n=3, 23.1%) were observed in the Peg-IFNα-2a group, while none were observed in the ETV group. Conclusion:Peg-IFNα-2a antiviral therapy produced higher HBsAg clearance than ETV in five-year-old and younger children with HBeAg-positive CHB, while ETV had fewer adverse events and was safer than Peg-IFNα-2a.

An essential step for cancer vaccination is to break the immunosuppression and elicit a tumor-specific immunity. A major hurdle against cancer therapeutic vaccination is the insufficient immune stimulation of the cancer vaccines and lack of a safe and efficient adjuvant for human use. We discovered a novel cancer immunostimulant, trichosanthin (TCS), that is a clinically used protein drug in China, and developed a well-adaptable protein-engineering method for making recombinant protein vaccines by fusion of an antigenic peptide, TCS, and a cell-penetrating peptide (CPP), termed an "all-in-one" vaccine, for transcutaneous cancer immunization. The TCS adjuvant effect on antigen presentation was investigated and the antitumor immunity of the vaccines was investigated using the different tumor models. The vaccines were prepared

Objective:To compare the baseline difference in the quantitative hepatitis B core antibody levels (qAnti-HBc) between non-response and response group in children with HBeAg-positive chronic hepatitis B (CHB) who received antiviral therapy, and further explore the proportion and functional activity of CD8 + memory T lymphocyte subsets with different qAnti-HBC levels in peripheral blood of children.Methods:The baseline anti-HBc quantification (qAnti-HBc) levels of 85 children with HBeAg-positive CHB who visited the Department of Infectious Diseases, Children's Hospital of Chongqing Medical University from June 2018 to December 2020 were detected retrospectively. The relationship between the baseline qAnti-HBc level and HBeAg serological response in 37 children who received antiviral therapy was analyzed. The proportion of CD8 + memory T lymphocyte subsets and the secretion levels of interferon (IFN) γ, and tumor necrosis factor (TNF) α in peripheral blood of 59 children at baseline were detected by flow cytometry. The relationship between qAnti-HBc level and the proportion and functional activity of CD8 + memory T lymphocyte subsets was analyzed. Pearson’s Chi-square test was used to compare the count data. Mann-Whitney U test or Kruskal-Wallis test was used to compare measurement data between two or more groups, and Spearman’s rank correlation analysis was used for the correlation between continuous variables. Results:Among 37 children who received entecavir (ETV, 21/37 cases) or pegylated interferon (Peg-IFN, 16/37 cases), 18 cases had developed HBeAg seroconversion (10/ 21 cases in the ETV group, 8/16 cases in the Peg-IFN group). The baseline qAnti-HBc level was significantly higher in the response group [4.71 (4.64~4.81) log 10IU/ml] than the non-response group children [4.54 (4.45~4.64) log 10IU/ml, Z = -3.316, P = 0.001]. The proportion of CD8 + Tem, CD38 +CD8 + Tem, CD38 +CD8 + Temra cells and the levels of IFNγ and TNFα secreted by CD8 + T lymphocytes were significantly higher in the high-qAnti-HBc group than the low-qAnti-HBc group ( P < 0.05). The proportion of CD8 + Tem, CD38 +CD8 + Tem and CD38 +CD8 + Temra cells was significantly higher in ALT > 1× upper limit of normal value (ULN) group than ALT≤1×ULN group ( P < 0.05). However, there were no significant differences in the levels of IFNγ and TNFα secreted by CD8 + T lymphocytes between the two groups ( P > 0.05). Spearman’s correlation analysis showed that qAnti-HBc was positively correlated with the proportion of CD8 + Tem, CD38 +CD8 + Tem, CD38 +CD8 + Temra cells and the level of IFNγ secreted by CD8 +T lymphocytes ( P < 0.05). Additionally, ALT was only positively correlated with the proportion of CD38 +CD8 + TEM and CD38 + CD8 + Temra cells ( P < 0.05). Conclusion:Raised baseline qAnti-HBc level is related to the HBeAg serological response to antiviral therapy in children with CHB. Peripheral blood effector CD8+ T lymphocytes of CHB children with higher qAnti-HBc show stronger phenotype and functional activation characteristics, which may shed some light on the underlying immune mechanism related to antiviral therapy efficacy in children with CHB.

Objective:To evaluate the optimized effect of infiltration between the popliteal artery and the capsule of the knee (IPACK)-adductor canal block (ACB) combined with general anesthesia when used for the total knee arthroplasty.Methods:Sixty patients of both sexes, aged 18-64 yr, with body mass index of 18-24 kg/m 2, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, scheduled for elective unilateral total knee arthroplasty, were divided into 2 groups ( n=30 each) using a random number table method: IPACK-ACB combined with general anesthesia group (group IA) and conventional anesthesia femoral nerve block-popliteal superior sciatic nerve block combined with general anesthesia group (group C). Before induction of general anaesthesia, 0.375% ropivacaine 15 ml was injected for IPACK and 0.375% ropivacaine 25 ml for ACB under the ultrasound guidance in group IA, femoral nerve block and popliteal superior sciatic nerve block was performed under the guidance of ultrasound combined with a nerve stimulator and 0.375% ropivacaine 20 ml was injected in group C. After confirming the efficacy of nerve block, total intravenous anesthesia was carried out to maintain bispectral index values at 40-60.Patient-controlled intravenous analgesia was performed with sufentanil after operation, and the visual analog scale score was maintained ≤ 3.The quadriceps muscle strength score was recorded when discharge from postanesthesia care unit and at 24, 48 and 72 h after surgery.The first postoperative off-bed time and development of foot drop in awake patients after surgery, requirement for rescue analgesia and adverse reactions were recorded.The postoperative length of hospital stay and score for patients′ satisfaction with postoperative recovery were also recorded. Results:Compared with group C, the postoperative quadriceps muscle strength scores and score for patients′ satisfaction with postoperative recovery were significantly increased, the incidence of postoperative foot drop was decreased, and the length of hospital stay and first postoperative off-bed time were shortened in group IA ( P<0.05). Conclusion:IPACK-ACB combined with general anesthesia may be an optimized strategy which is helpful for outcomes after total knee arthroplasty.

Objective To study the relationship between climatic factors and cerebral hemorrhagic disease.Methods A total of 1125 cerebral hemorrhage patients were included in this study.The relationship between the onset time of cerebral hemorrhage and daily climatice factors (including temperature,humidity,atmospheric pressure,wind direction and rainfall volume) was analyzed and the onset time of cerebral hemorrhage in each patient was analyzed according to the X2 test for goodness of fit.Results The number of male cerebral hemorrhagy patients was greater than that of female cerebral hemorrhage patients.The mean age of femalc cerebral hemorrhage patients was older than that of male cerebral hemorrhage patients (P＜0.01).The incidence of cerebral hemorrhage accounted for 11％ in January in a greatest number of such patients,accounted for 5.0％ in September in a smallest number of such paticnts,and was the highest at h 4-8 AM and at h 16-20 FM in ≤45 years old cerebral hemorrhage patients.Univariate correlation analysis showed that cerebral hemorrhage was negatively related with daily mean temperature,daily mean maximal and minimal temperature (r=-0.157,r =-0.163,r=-0.156,P＜0.05),positively related with daily mean atmospheric pressure (r=0.157,P＜0.05).Multivariate linear stepwise analysis showed that cerebral hemorrhage was related with daily mean temperature,maximal and minimal temperature,and daily mean atmospheric pressure (P＜0.05,P＜0.01).Conclusion The incidence of cerebral hemorrhage differs in seasons and months,is higher in winter and lower in summer,and is thus related with temperature,atmospheric pressure and wind direction.

Nanotechnology-based photothermal therapy has attracted great attention in the past decade. Nevertheless, photothermal therapy has some inherent drawbacks, such as the uneven heat production and limited laser penetration, often leading to insufficient treatment outcomes. Here, we developed a combination strategy to improve cancer therapy. The biomimetic albumin-modified gold nanorods (AuNRs) were prepared with incorporation of paclitaxel (PTX). This therapeutic system was characterized by several features. First, the albumin modification enhanced the biocompatibility and colloidal stability. Second, the surface-coated albumin promoted cellular uptake the albumin-binding protein pathway. Third, PTX was incorporated hydrophobic interaction between PTX and the albumin lipophilic domain. Fourth, the system can be used for combined photothermo-chemotherapy for yielding synergistic effects. The antitumor activity of the system was evaluated both and using the HCT116 colon cancer cell and tumor model. The combination therapy was found with an enhanced treatment efficiency and no obvious side effect. Most importantly, the thermal effect was also discovered with the ability to modulate the tumor microenvironments and suppress the macrophages polarization towards the M2 pro-tumor phenotype. It could be a mechanism for photothermal immunotherapy. The combination strategy and the system provide a potential method for cancer therapy.
