Aging has emerged as a cutting edge and hotspot in global life science field， with anti-aging and geriatric disease prevention and treatment becoming critical issues urgently demanding solutions in international medical communities. In the face of the challenge of accelerating global population aging， in-depth exploration of aging mechanisms and the development of effective intervention strategies hold significant scientific and clinical value. This study supported by the national key research and development program of China， employed the essence-Qi-spirit theory of Qiluo doctrine as its guiding framework， focusing on the key scientific issue of the core traditional Chinese pathogenesis of aging， namely "depletion of kidney essence， deficiency of primordial Qi， and impairment of body and spirit". The treatment principle of "tonifying the kidney to replenish essence， harmonizing Yin and Yang， warming and invigorating primordial Qi， and nourishing the body and spirit" was established. Centered on holistic aging， systemic aging， and aging-related diseases， the research integrated multidisciplinary research approaches to construct multi-modal aging models and a multi-dimensional evaluation system， and it utilized multi-omics technologies to deeply analyze aging mechanisms. By systematically reviewing historical kidney-tonifying and anti-aging formulas and combining big data with artificial intelligence technologies， an information database of anti-aging traditional Chinese medicine substance was developed to reveal the differences and synergistic effects of various treatment methods and formulas on anti-aging. Based on this treatment method， the research integrated two millennia of kidney-tonifying medicinal experience to develop the innovative anti-aging traditional Chinese medicine， namely Bazhi Bushen capsules. It was validated that this capsule can delay holistic and systemic aging through multiple targets and mechanisms， thereby elucidating the scientific connotation of the essence-Qi-spirit theory of Qiluo doctrine in guiding anti-aging research from multiple dimensions and providing robust support for leveraging the advantages of traditional Chinese medicine to occupy the commanding heights of international anti-aging research.

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.

With the continuous development of new surgical technology, new equipment and new concepts, the research focused in the field of surgery is also in constant change. Among them, there are still confusion and controversies in the current clinical practice when facing the one-stop proposition of benefit population screening, advantageous surgical indication decision-making, surgical intervention timing selection, postoperative complication prediction and management. Therefore, our team tries to analyze whether the concept of"co-management of liver and pancreas"exists in clinical practice from the aspects of anatomy, physiology, histology and embryology of liver and pancreas, as well as the interaction between liver and pancreas, and explore the relationship between liver and pancreas in anatomy and tissue embryonic development, and the relationship between the concept of"co-management of liver and pancreas"and pancreatitis and pancreatic tumors as well as the concept of “co-management of liver and pancreas” applied in neoadjuvant chemoradiotherapy, and attempts to establish a new treatment pathway for pancreatic diseases based on this concept, in order to provide a new idea, new scheme and new possibility for the clinical research of pancreatic diseases and pancreatic surgery.

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.

Objective:To investigate the efficacy of lower face-lift combined with superficial musculoaponeurotic system (SMAS) flap augmentation in correcting nasolabial fold depression.Methods:A retrospective cohort of 26 female patients who underwent lower face-lift at the Third Affiliated Hospital of Zhengzhou University from June 2019 to December 2021 was included, with ages ranging from 45 to 63 (54.1±4.8) years. Patients were allocated into two groups according to surgical methods: 12 cases in the control group received lower face-lift alone, and 14 cases in the observation group underwent lower face-lift combined with SMAS flap augmentation of the nasolabial fold. Postoperative (face questionnaire,FACE-Q) scores at 3 months were compared between the two groups. In the observation group, modified Fitzpatrick wrinkle scale (MFWS) scores were compared before treatment and at 3, 6, and 12 months after surgery to assess improvement of nasolabial fold depression.Results:In the observation group, overall satisfaction with facial appearance, nasolabial fold assessment, and aging evaluation visual analog scores were (86.2±5.1), (86.9±7.3), and (88.2±6.7) scores, respectively, compared with (79.9±5.6), (76.3±7.0), and (79.6±5.4) scores in the control group, with statistically significant differences (all P<0.01). In the observation group, MFWS scores of nasolabial fold depression at 3, 6, 12 months after surgery decreased 2.3, 2.1, and 1.9 scores, respectively. Conclusion:Lower face-lift combined with SMAS flap augmentation achieves superior improvement in nasolabial fold depression.

Objective:To evaluate the efficacy and safety of sintilimab combined with bevacizumab in the second-line treatment of malignant pleural mesothelioma(MPM).Methods:This was a longitudinal study. Patients with MPM who had progressed after first-line treatment and were admitted to the Day-Care Outpatient Department of Medical Oncology, Ningguo People′s Hospital from February 2019 to February 2022 were included. General clinical data of the patients were collected at baseline. The patients were treated with the second-line treatment regimen of sintilimab (200 mg)+bevacizumab (15 mg/kg) on a 21-day cycle. Enhanced CT scans were performed every 3 cycles to evaluate the efficacy until tumor progression or death. Follow-up period ended in December 2023. The primary endpoints were progression-free survival (PFS) and overall survival (OS). Efficacy was evaluated according to the modified Response Evaluation Criteria in Solid Tumors (mRECIST), and the best response of each patient was recorded. The objective response rate (ORR) and disease control rate (DCR) were calculated. Adverse reactions were graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE), ranging from grade Ⅰto Ⅳ. Kaplan-Meier survival curves were used to analyze PFS and OS, and survival times were expressed as median values.Results:A total of 23 MPM patients were included, with the mean age of (55.04±13.27)years, 15 males, 8 females, 19 cases of epithelial type and 4 cases of non-epithelial type. The Eastern Cooperative Oncology Group (ECOG) performance status scores were 0-1 in 12 patients and 2 in 11 patients. There were 17 smokers and 6 non-smokers, 12 cases with PD-L1 positive and 11 cases with PD-L1 negative, and 6 cases with anti-angiogenic drugs and 17 cases without using anti-angiogenic drugs in the first-line treatment. Of the 23 patients, 1 achieved complete response (CR), 9 achieved partial response (PR), 7 had stable disease (SD), and 6 had progressive disease (PD). The ORR and DCR of the enrolled patients were 43.5% (10/23) and 73.9% (17/23), respectively. Kaplan-Meier survival analysis showed that the PFS of the enrolled patients was 7.50 (95% CI: 5.47-9.54) months, and the OS was 12.50 (95% CI: 1.07-23.93) months. The most common adverse reactions related to the treatment of sintilimab combined with bevacizumab were hypertension (14 cases (60.9%)), fatigue (10 cases (43.5%)), decreased appetite (8 cases (34.8%)), proteinuria (6 cases (26.1%)), pruritus (5 cases (21.7%)), constipation (4 cases (17.4%)) and nausea (3 cases (13.0%)), etc. Only 9 patients had grade Ⅲ adverse reactions (8 cases of hypertension and 1 case of nausea), and only 1 patient had grade Ⅳ adverse reaction (hypertension). Conclusion:Sintilimab combined with bevacizumab has some therapeutic effects on progressive MPM, and the adverse reactions are relatively mild.

Objective:To analyze the short-term efficacy and safety of robot-assisted laparoscopic partial nephrectomy（RAPN）for non-metastatic pathological stage T 3a renal cell carcinoma. Methods:The clinical and pathological data of 45 patients with pathologically confirmed non-metastatic T 3a renal cell carcinoma who underwent RAPN at Sun Yat-sen University Cancer Center between January 2016 and December 2023 were retrospectively reviewed. There were 30 males and 15 females. The average age of the cohort was（54.3±10.7）years，and the average clinical tumor diameter was（4.9±1.8）cm. Of all the patients，35（77.8%）were asymptomatic，7（15.6%）presented with hematuria，and 3（6.7%）presented with lumbar pain. Preoperative imaging assessed 34 patients（75.6%）as having clinical stage T 3a，all suspected of involving the collecting system or perirenal fat invasion；the remaining 11 patients（24.4%）were assessed as having stage T 1-2 disease. The median R.E.N.A.L. nephrectomy score was 8.0（7.0，10.0）. A history of hypertension，diabetes，or chronic kidney disease was present in 18 patients（40.0%）. The primary endpoint was progression-free survival，and the secondary endpoints included postoperative complications and short-term renal function outcomes. Survival curve was estimated using the Kaplan-Meier method，and renal function comparisons were made using the paired t-test. Results:The RAPN was performed through a transabdominal approach in 32 patients（71.1%），with a median estimated blood loss of 150.0（50.0，300.0）ml. Seven（15.6%）patients required intraoperative blood transfusion. The median length of postoperative hospital stay was 4.0（4.0，6.0）days. Postoperative complications occurred in 6 patients（13.3%），including 5（11.1%）with mild complications and 1（2.2%）with a severe complication. Renal function returned to baseline in 24 of 39 evaluable patients（61.5%），while 3 patients（7.7%）developed surgery-related chronic kidney disease 3 to 12 months postoperatively，but none required dialysis. The median follow-up time was 31.8（22.7，50.9）months，12（26.7%）patients received programmed cell death protein 1 inhibitor adjuvant therapy postoperatively. During follow-up，3 patients experienced tumor recurrence，the 3-year progression-free survival rate of the entire cohort was 95.4%.Conclusions:For some carefully selected patients with T 3a renal cell carcinoma，RAPN performed by experienced surgeons is a feasible and safe option，providing excellent short-term oncological outcomes，complication control，and renal function recovery. The long-term efficacy remains to be seen.

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.
