arcopenia is a systemic skeletal muscle disorder characterized by a decrease in skeletal muscle mass and progressive decline in function， with multiple signaling pathways involved in its occurrence and development. Among them， the AMP-activated protein kinase （AMPK） signaling pathway， as a key pathway regulating cellular energy homeostasis， plays an important role in the regulation of skeletal muscle metabolism and functional maintenance by improving abnormalities in glucose and lipid metabolism， balancing skeletal muscle protein synthesis and degradation， improving mitochondrial function， promoting autophagy， and inhibiting inflammatory responses and oxidative stress. This article reviews the research progress on how various traditional Chinese medicine （TCM） monomers， including polyphenols， flavonoids， and terpenoids； various traditional Chinese medicine extracts， such as those from Lycium barbarum ， Asini Corii Colla， and Panax quinquefolium ， and TCM compounds， such as Guiqi zhuangjin decoction， Jianpi qiangji granules， and Qigu capsules， intervene in sarcopenia by regulating the AMPK signaling pathway to promote muscle protein synthesis， inhibit protein degradation， improve mitochondrial function， and alleviate inflammation and oxidative stress. Additionally， their molecular mechanisms are explored. The aim is to deeply elucidate the basis of TCM in the prevention and treatment of sarcopenia and to provide theoretical support for the development of related innovative drugs.

Background: Epithelial ovarian cancer is the leading cause of death among gynecological malignancies. Platinum resistance remains a dilemma and bottleneck in treatment, and salvage chemotherapy has limited effectiveness. Recently, the role of secondary cytoreductive surgery (SCS) in patients with platinum-resistant recurrent ovarian cancer (ROC) has caused attention especially in patients with oligometastases. However, there is neither high-quality evidence-based evidence nor standardized criteria for selecting SCS for patients with platinum-resistant ROC until now. Methods This multicenter, randomized, controlled clinical trial is to evaluate the value of SCS and to clarify reliable criteria of utilizing SCS in women with ROC, which is led by Gynecologic Oncology Group, Women’s Hospital, Zhejiang University School of Medicine.Recruitment has started on January 1st, 2023, and is scheduled to end in December 2026.One hundred and forty participants with platinum-resistant ROC who meet the “RSCS criteria” will be randomized assigned at a ratio of 1:1 to either the experimental arm or the standard arm. Patients in the experimental arm will receive SCS followed by non-platinum single agent chemotherapy (paclitaxel, gemcitabine or liposomal adriamycin) for at least 4 cycles while patients in the standard arm will be provided with only non-platinum single agent chemotherapy. The primary outcome is progression-free survival. The secondary outcomes are overall survival, adverse events and health-related cancer-specific quality of life.

Objective To systematically evaluate the efficacy and safety of Compound Danshen Dripping Pills combined with conventional western medicine in the treatment of coronary heart disease complicated with diabetes mellitus.Methods Wanfang database,CNKI,VIP,SinoMed,Cochrane Library,PubMed,Embase and Web of Science databases were searched to collect randomized controlled trials(RCTs)of Compound Danshen dripping pills combined with conventional western medicine in the treatment of coronary heart disease complicated with diabetes mellitus.The retrieval time is from the establishment of the database to May 2023.Two researchers independently completed literature screening,data collation and risk of bias evaluation.RevMan 5.4 software was used for Meta-analysis.Results Twenty-four RCTs with a total of 2 546 patients were included.Meta-analysis showed that the treatment of Compound Danshen Dripping Pills combined with conventional western medicine was better than that of conventional western medicine in improving the total effective rate of coronary heart disease complicated with diabetes mellitus[OR=4.93,95%CI(3.49,6.98),P＜0.000 01],plasma adiponectin[MD= 2.79,95%CI(2.30,3.27),P＜0.000 01],reducing fasting blood glucose[SMD=-1.06,95%CI(-1.24,-0.88),P＜0.000 01],postprandial two-hour blood glucose[MD=-1.53,95%CI(-1.71,-1.35),P＜0.000 01],glycosylated hemoglobin[MD=-1.56,95%CI(-2.01,-1.11),P＜0.000 01],homocysteine[MD=-8.47,95%CI(-8.89,-7.97),P＜0.000 01],low density lipoprotein[MD=-0.46,95%CI(-0.69,-0.24),P＜0.000 01],total cholesterol[MD=-0.45,95%CI(-1.11,-0.20),P=0.005],triglycerides[MD=-0.42,95%CI(-0.50,-0.34),P＜0.000 01],interleukin 6[SMD=-1.34,95%CI(-1.61,-1.07),P＜0.000 01],cardiovascular adverse events[OR=0.35,95%CI(0.19,0.64),P=0.000 6],incidence of adverse reactions[OR=0.45,95%CI(0.24,0.86),P=0.01].Conclusion Compound Danshen Dripping Pills combined with conventional western medicine in the treatment of coronary heart disease with diabetes mellitus is more effective than conventional western medicine treatment,and with better safety.However,due to the limit of the quality of the included studies and other factors,the above conclusions still need to be verified by more high-quality clinical trials.

Objective:To explore the application of bilateral autogenous auricular concha cartilage graft in the construction of nasal tip cartilage complex in comprehensive rhinoplasty.Methods:From January 2016 to June 2019, a total of 521 rhinoplasty patients in the Second Xiangya Hospital and in the Health Medical Cosmetic Hospital received the operation, including 310 patients with primary rhinoplasty and 211 patients with secondary rhinoplasty. There were 12 males and 509 females, aged 18-53 years. Contracted nose patients with severe tissue destruction were excluded. The operation method: the bilateral auricular concha cartilage was cut and combined, including the nasal columella support graft, the anti derotation graft and the cap graft, and the combination of the nasal tip framework complex was constructed to shape the nasal tip framework. At the same time, the expanded polytetrafluoroethylene or silicone prosthesis was carved into willow leaf shape to elevate the bridge of the nose. Patients were followed up after operation. Physicians, patients and a third party were asked to evaluate the preoperative and postoperative photos of more than 6 months to evaluate the surgical effect. The results suggested that the three parties were regarded as significantly effective, two parties satisfied as effective, one party satisfied as average, all dissatisfied as poor; postoperative complications such as infection and prosthesis exposure were judged as invalid. At the same time, the changes of nose tip height and nose length were measured.Results:521 patients in this group got satisfactory appearance effect immediately after operation. After 6-24 months follow-up, the shape of the nose tip remained good, the color of blood circulation was normal, the appearance of the nose tip was natural and beautiful, three-dimensional and straight. Among the 521 cases, 471 cases were significantly improved, 30 cases were improved, 15 cases were acceptable and other 5 cases were poor. The satisfaction rate was 96% (501/521). The average height of nasal tip was(3.5±0.3) mm higher than that before operation. The average length of nose was(4.9±0.4) mm longer than that before operation.Conclusions:The combination of auricular concha cartilage framework and silica gel prosthesis or expanded polytetrafluoroethylene can be used as a routine method for primary rhinoplasty and secondary rhinoplasty.

Objective: To explore the establishment and application of three-dimensional model of deep inferior epigastric artery perforator flap based on computed tomography angiography (CTA). Methods: Six patients with breast absence after modified radical mastectomy because of breast cancer, 5 patients with congenital absence of vagina, and 6 patients with Paget′s disease of penis and scrotum were hospitalized in our unit from January 2012 to April 2017. The size of wounds after excision of the lesion or that of flaps needed for reconstruction ranged from 17 cm×5 cm to 25 cm×9 cm. Abdominal CTA was performed before the surgery, and data of CTA were sent to CT workstation to make three-dimensional model of deep inferior epigastric artery perforator flap according to shape and size of wound. The number, course, and location of deep inferior epigastric artery, vein, and their perforators, and the superficial inferior epigastric vein were observed in the above-mentioned three-dimensional model. The rectangular plane coordinate system with the umbilicus as the origin was established to locate and observe course and type of the largest deep inferior epigastric artery perforator in left and right side. Deep inferior epigastric artery perforator flaps were designed and deep inferior epigastric artery perforators etc. were marked according to three-dimensional models of the flaps before the surgery. The condition observed in three-dimensional model of the flap was compared with the clinical condition in the surgery of free transverse bilateral deep inferior epigastric artery perforator flap transplantation for breast reconstruction and longitudinal pedicled thinned unilateral deep inferior epigastric artery perforator flap transplantation for vagina reconstruction and wound repair of Paget′s disease of penis or scrotum. The size of flap ranged from 17 cm×6 cm to 25 cm×10 cm. Results: Seventeen three-dimensional models of deep inferior epigastric artery perforator flaps were established, including 6 bilateral models and 11 unilateral models. Seventy-two reliable deep inferior epigastric artery perforators were observed in the three-dimensional model with 3.2±0.7 in the right and 3.1±0.8 in the left. The locations of the largest deep inferior epigastric artery perforators in the right and left were [(-3.2±1.4) cm, (-1.0±0.7) cm] and [(4.0±1.2) cm, (-1.2±1.1) cm] respectively. Fourteen largest deep inferior epigastric artery perforators coursed directly and nine coursed tortuously in the rectus muscle. Twenty-three superficial inferior epigastric veins were detected in the three-dimensional models of the flaps. The number, location, and course of deep inferior epigastric artery and vein and superficial inferior epigastric vein observed in the three-dimensional model of deep inferior epigastric artery perforator flap were in accordance with the condition observed in the surgery. Seventy reliable deep inferior epigastric artery perforators were detected in the surgery, and the other 2 perforators were unclear due to bleeding. Course of these perforators were in accordance with the condition observed in the three-dimensional model. Deep inferior epigastric artery perforator flaps of all patients survived well with no complication except that 1 patient suffered from delayed healing of wound in perineum. During follow-up of 1 to 12 months, all flaps survived with good shape and texture. Conclusions The three-dimensional model of deep inferior epigastric artery perforator flap based on CTA can be established easily and can provide information of number, location, and course of deep inferior epigastric artery, vein, and their perforators, and superficial inferior epigastric vein to guide preoperative design and intraoperative dissection of the flap effectively.
