Attention deficit hyperactivity disorder （ADHD） is often accompanied by tic disorder. The core pathogenesis is considered to be ministerial fire scorching yin and internal stirring of deficient wind， which leads to disharmony between the body and spirit， resulting in clinical manifestations. The treatment principles emphasize nourishing yin fluids， calming ministerial fire， and extinguishing endogenous wind （内风）. The method of nourishing yin fluids is applied throughout the entire treatment process， commonly using ingredients such as Shudihuang （Rehmanniae Radix Praeparata）， Shanzhuyu （Corni Fructus）， Gouqizi （Lycii Fructus）， Wuweizi （Schisandrae Chinensis Fructus）， and Tusizi （Cuscutae Semen）. These are combined with approaches to harmonize the zang-fu organs， primarily including extinguishing liver wind， clearing heart fire， nourishing kidney water， and strengthening spleen earth， thereby stabilizing ministerial fire and extinguishing endogenous wind. Additionally， emotional regulation and smoothing emotional constraint are essential to improve clinical symptoms in children with ADHD comorbid with tic disorder.

Diabetic retinopathy（DR）， as one of the most common and serious microvascular complications of diabetes mellitus， seriously threatens human health， and belongs to "Xiaoke eye diseases" in traditional Chinese medicine（TCM）， which has been richly experienced by medical practitioners through the ages， but is mostly recorded in a piecemeal manner and has not been systematically researched. This disease is featured by long course and repeated attack， and is refractory， which belongs to the research category of "persistent illness entering collaterals". Systematic establishment of TCM collateral disease theory for guiding prevention and treatment of DR has important clinical value. On the basis of close correlation between tertiary collaterals at the terminal of collaterals and capillaries and microcirculation， the concept of "tertiary collaterals-microvascular" is proposed. It is pointed out that DR falls within the scope of "tertiary collaterals-microvascular" diseases， and presents four types of micro-pathological characteristics， including stasis， insufficiency， growth and bleeding of tertiary collaterals. It is concluded that "deficiency of both Qi and Yin" is the basic pathogenesis of DR， and "blood stasis and collateral obstruction" is the important pathogenesis and key factor. Thus， the treatment method of "dispersing blood stasis， dredging collateral， tonifying Qi and Yin， stopping hemorrhage and improving eyesight" is determined， and the formula of Tongluo Mingmu capsules is developed. The article tightly focuses on the pathological changes such as stasis， growth， insufficiency and bleeding of collaterals， addresses both symptoms and root causes， and plays a synergistic role of both dispersing stasis and stopping bleeding. In this way， it can realize the purpose of tonifying Qi and Yin to replenish the essence， dispersing stasis and dredging collaterals to meet the requirement， as well as stopping hemorrhage and improving eyesight to deal with changes. Fundamental researches demonstrate that Tongluo Mingmu capsules has synergy effects of protecting both retinal capillaries and retinal cells. Phase-Ⅲ clinical trial of new drug has proven definite clinical efficacy and good safety， which provides a new drug choice for enhancing clinical effect of DR， and further supports the scientific value of Luobing theory in preventing and treating DR and other clinically significant diseases.

ObjectiveThe full name of vertebroplasty is percutaneous vertebroplasty (PVP). It is a clinical technique that injects bone cement into the diseased vertebral body to achieve strengthening of the vertebra. The research on the safety and efficacy of bone cement is the basis for clinical application. In this study, vertebroplasty is used to evaluate and compare the safety and efficacy of Tecres and radiopaque bone cement in experimental pigs, and to determine the puncture method suitable for pigs and the pre-clinical evaluation method for the safety and efficacy of bone cement. MethodsTwenty-four experimental pigs (with a body weight of 60-80 kg) were randomly divided into an experimental group (Group A) and a control group (Group B). Group A was the Tecres bone cement group, and Group B was the radiopaque bone cement group, with 12 pigs in each group. Under the monitoring of a C-arm X-ray machine, the materials were implanted into the 1st lumbar vertebra (L1) and 4th lumbar vertebra (L4) of the pigs via percutaneous puncture using the unilateral pedicle approach. The animals were euthanized at 4 weeks and 26 weeks after the operation, respectively. The L4 vertebrae were taken for compressive strength testing, and the L1 vertebrae were taken for hard tissue pathological examination to observe the inflammatory response, bone necrosis, and degree of osseointegration at the implantation site. ResultsThe test results of compressive strength between groups A and B showed no significant difference at 4 weeks and 26 weeks after bone cement implantation (P > 0.05). Observation under an optical microscope (×100) revealed that at 4 weeks postoperatively, both groups A and B showed that the bone cement was surrounded by proliferative fibrous tissue, with lymphocyte infiltration around it. The bone cement was combined with bone tissue, the trabecular arrangement was disordered, and osteoblasts and a small amount of osteoid were formed. At 26 weeks postoperatively, bone cement was visible in both groups A and B. The new bone tissue was mineralized, the trabeculae were fused, the trabecular structure was regular and dense with good continuity, and no obvious inflammatory reaction was observed. ConclusionIn experimental pig vertebrae, there were no significant differences observed in the compressive strength, inflammation response, bone destruction, and integration with the bone between Tecres and non-radiopaque bone cement. Both exhibited good biocompatibility and osteogenic properties. It indicates that using vertebroplasty to evaluate the safety and efficacy of bone cement in pigs is scientifically sound.

Central memory T (Tcm) cells are a crucial subset in T cell development, playing an important role in long-term immune responses. Tcm cells exhibit strong proliferative capacity, long-term survival characteristics, and re-activation potential, enabling them to rapidly differentiate into effector T cells (Teff) upon antigen re-exposure, thus providing robust immune protection. The function of Tcm cells is regulated by various factors, including antigen exposure, cytokines, and metabolic conditions. A deeper understanding of their metabolic and epigenetic mechanisms under different pathological conditions will contribute to the development of more precise and effective immunotherapeutic strategies. This review elaborates on the origin and characteristics of Tcm cells, as well as their roles in antiviral responses, tumor immunity, and immunotherapy.

Objective To investigate the effect of palmitoleic acid(POA)on pyroptosis of cardiomyocytes after hy-poxia/reoxygenation-induced injury in the human myocardium.Methods The experiment comprised a control group(Control,normal culture),a hypoxia/reoxygenation group(HR),a palmitoleic acid-treated group(HR+POA),and an anhydrous ethanol control group(HR+ET).Cardiomyocytes viability was assessed using CCK-8 assay,and the level of pyroptosis of cardiomyocytes was measured through the double staining with Hoechst33342/PI and LDH assay.ELISA was employed to detect the release of inflammatory factors IL-1 β and IL-18 in the cell culture supernatant.qRT-PCR and Western blot were utilized to determine the relative expression levels of mRNA and protein of pyroptosis-related genes,namely NLRP3,ASC,Caspase-1,GSDMD,IL-1 β and IL-18,respective-ly.Results CCK-8 assay showed that the survival of hypoxic/reoxygenated cardiomyocytes increased with the ad-dition of POA at concentrations ranging from 25 to 100 μmol/L,as compared to the HR group;a hypoxia/reoxy-genation model of cardiomyocyte was established.The expression of protein and mRNA increased in NLRP3,ASC,Cleaved caspase-1,GSDMD-N,IL-Iβ and IL-18 vs the control group(P＜0.05),the positive percentage of Ho-echst33342/PI staining in cardiomyocytes increased significantly(P＜0.05),the release of LDH,IL-Iβ,and IL-18 increased(P＜0.05).After intervention with 100 μmol/L POA,the protein and mRNA expression levels of NLRP3,ASC,Cleaved caspase-1,GSDMD-N,IL-Iβ,and IL-18 were significantly reduced in the HR+POA group vs HR+ET group(P＜0.05).The positive percentage of Hoechst33342/PI staining in cardiomyocytes de-creased significantly,and the levels of LDH,IL-Iβ and IL-18 significantly decreased(P＜0.05).Conclusion Palmitoleic acid may alleviate hypoxia/reoxygenation-induced injury of cardiomyocytes by inhibiting pyroptosis and inflammatory response after hypoxia/reoxygenation in human myocardium.

Background::Bladder cancer, characterized by a high potential of tumor recurrence, has high lifelong monitoring and treatment costs. To date, tumor cells with intrinsic softness have been identified to function as cancer stem cells in several cancer types. Nonetheless, the existence of soft tumor cells in bladder tumors remains elusive. Thus, our study aimed to develop a microbarrier microfluidic chip to efficiently isolate deformable tumor cells from distinct types of bladder cancer cells.Methods::The stiffness of bladder cancer cells was determined by atomic force microscopy (AFM). The modified microfluidic chip was utilized to separate soft cells, and the 3D Matrigel culture system was to maintain the softness of tumor cells. Expression patterns of integrin β8 (ITGB8), protein kinase B (AKT), and mammalian target of rapamycin (mTOR) were determined by Western blotting. Double immunostaining was conducted to examine the interaction between F-actin and tripartite motif containing 59 (TRIM59). The stem-cell-like characteristics of soft cells were explored by colony formation assay and in vivo studies upon xenografted tumor models. Results::Using our newly designed microfluidic approach, we identified a small fraction of soft tumor cells in bladder cancer cells. More importantly, the existence of soft tumor cells was confirmed in clinical human bladder cancer specimens, in which the number of soft tumor cells was associated with tumor relapse. Furthermore, we demonstrated that the biomechanical stimuli arising from 3D Matrigel activated the F-actin/ITGB8/TRIM59/AKT/mTOR/glycolysis pathways to enhance the softness and tumorigenic capacity of tumor cells. Simultaneously, we detected a remarkable up-regulation in ITGB8, TRIM59, and phospho-AKT in clinical bladder recurrent tumors compared with their non-recurrent counterparts.Conclusions::The ITGB8/TRIM59/AKT/mTOR/glycolysis axis plays a crucial role in modulating tumor softness and stemness. Meanwhile, the soft tumor cells become more sensitive to chemotherapy after stiffening, that offers new insights for hampering tumor progression and recurrence.

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.

BACKGROUND:High ankle sprain is easily missed and leads to ankle dysfunction.Arthroscopy can detect hidden high ankle sprain.Suture-button elastic fixation can restore the biomechanical stability of the distal tibiofibular syndesmosis. OBJECTIVE:To explore the clinical efficacy of Suture-button elastic fixation for high ankle sprain under ankle arthroscopy. METHODS:A retrospective analysis was performed on 40 cases of high ankle sprain patients treated with Suture-button elastic fixation under ankle arthroscopy from August 2019 to August 2021 in the Department of Foot and Ankle Surgery,Wuhan Fourth Hospital.All patients underwent Suture-button elastic fixation.The American Orthopedic Foot and Ankle Society function score,Visual Analog Scale pain score,ankle range of motion,preoperative imaging data,and arthroscopic tibiofibular syndesmosis separation degree were recorded.Meislin criteria were used to evaluate the curative effect and postoperative complications were recorded. RESULTS AND CONCLUSION:(1)40 patients were followed up for 16-48 months after operation.(2)At the last follow-up,American Orthopedic Foot and Ankle Society score was(88.95±6.64 points).Visual Analog Scale score was(1.78±1.23 points).Ankle dorsiflexion range of motion was(33.50±5.79 degrees).Ankle plantarflexion range of motion was(34.50±5.97 degrees).There were statistically significant differences before and after surgery(P<0.05).(3)There was a low positive correlation between the radiographic separation index and the degree of arthroscopic separation(r=0.612,P<0.01).(4)The curative effect was evaluated by Meislin standard,with an excellent and good rate of 95%(38/40).Postoperative ankle joint pain was relieved,and ankle joint activities were significantly improved.(5)During the follow-up period,all patients had no nerve injury or incision infection.In 1 patient,the internal fixation was removed due to skin irritation and squatting sensation after operation.(6)It is concluded that Suture-button elastic fixation for high ankle sprain is effective under ankle arthroscopy in restoring ankle function and maintaining joint stability without the need for secondary removal,and it is worth clinical application.

Objective:To investigate the relationship between thyroid function abnormality-immune related adverse event (TFA-irAE) and treatment efficacy and survival in advanced cancer patients treated with programmed death-1 (PD-1) inhibitors.Methods:The clinical data of 90 patients with advanced cancer who received 6 cycles of PD-1 inhibitor treatment from January 2021 to June 2022 in Department of Oncology of Yuncheng Central Hospital Affiliated to Shanxi Medical University were collected. Serum levels of thyroid stimulating hormone (TSH), free thyroxine (FT 4), thyroid peroxidase antibody (TPOAb), and thyroglobulin antibody (TGAb) were measured by chemiluminescence immunoassay in patients after PD-1 inhibitor treatment, and the incidence of TFA-irAE was observed in the patients after 6 cycles of therapy. According to the occurrence of TFA-irAE, the patients were divided into TFA-irAE occurrence group ( n=40) and TFA-irAE non-occurrence group ( n=50), the therapeutic efficacy and survival of the two groups were calculated and compared. The thyroid function indexes of patients with different efficacy (33 cases in effective group and 57 cases in ineffective group) and patients with different prognosis (30 cases in survival group, 60 cases in death group) were compared, and the influencing factors of efficacy and survival were analyzed by multivariate logistic regression and Cox analysis. Kaplan-Meier survival curve was drawn, and the survival of TFA-irAE occurrence group and TFA-irAE non-occurrence group were compared by log-rank test. Results:One year after treatment, the treatment effective rate of TFA-irAE occurrence group and TFA-irAE non-occurrence group were 42.5% (17/40), 32.0% (16/50), respectively, with no statistically significant difference ( χ2=1.06, P=0.304). After 6 cycles of PD-1 inhibitor treatment, serum levels of TSH [ (2.56±0.41) mU/ml vs. (3.11±0.53) mU/ml], TPOAb [ (56.78±5.72) U/ml vs. (62.67±6.31) U/ml] and TGAb [ (81.57±8.23) U/ml vs. (92.34±9.31) U/ml] in the effective group were significantly lower than those in the ineffective group, with statistically significant differences ( t=4.45, P<0.001; t=3.89, P<0.001; t=5.29, P<0.001). The serum levels of TSH [ (2.69±0.46) mU/ml vs. (3.06±0.65) mU/ml], FT 4 [ (10.45±1.13) pmol/L vs. (11.50±1.36) pmol/L], TPOAb [ (56.27±5.61) U/ml vs. (62.47±6.34) U/ml] and TGAb [ (81.62±8.31) U/ml vs. (91.73±9.35) U/ml] in the survival group were significantly lower than those in the death group, with statistically significant differences ( t=2.27, P=0.025; t=3.02, P=0.003; t=3.79, P<0.001; t=4.19, P<0.001). Multivariate logistic regression analysis showed that TSH ( OR=1.52, 95% CI: 1.13-2.05, P=0.006), TPOAb ( OR=1.42, 95% CI: 1.13-1.78, P=0.002) and TGAb ( OR=1.35, 95% CI: 1.05-1.73, P=0.018) were all independent factors affecting the efficacy of patients with advanced cancer treated with PD-1 inhibitors. Multivariate Cox regression analysis showed that TSH ( HR=1.42, 95% CI: 1.06-1.92, P=0.030), TPOAb ( HR=1.31, 95% CI: 1.05-1.64, P=0.018), TGAb ( HR=1.41, 95% CI: 1.09-1.83, P=0.008) and FT 4 ( HR=1.36, 95% CI: 1.02-1.81, P=0.038) were all independent factors affecting the survival of patients with advanced cancer treated with PD-1 inhibitors. Survival analysis showed that the median overall survival in the TFA-irAE occurrence group and the TFA-irAE non-occurrence group were 10.8 and 8.0 months, respectively, with a statistically significant difference ( χ2=9.53, P=0.002) . Conclusion:Although the occurrence of TFA-irAE may have less effect on the efficacy of advanced tumor patients treated with PD-1 inhibitors, it may affect the survival of patients. TSH, TPOAb and TGAb are all independent influencing factors for the efficacy of patients with advanced tumors treated with PD-1 inhibitors, while TSH, TPOAb, TGAb and FT 4 are independent influencing factors for the survival of patients with advanced tumors treated with PD-1 inhibitors.
