The theoretical basis of premature aging originates from The Yellow Emperor's Inner Classic. The etiology of premature aging is complex， and the disease mechanism is based on deficiency. The treatment for premature aging is based on tonicity. The essence-Qi-spirit theory of Qiluo doctrine summarizes that "essence is the origin of life， Qi is the driving force of life， and spirit is the embodiment of life"， which is the law of life. The theory puts forward the core disease mechanism of aging， which states that "deficiency of kidney essence is the root of aging， deficiency of primordial Qi is the key to aging， impairment of soma and spirit is the manifestation of aging". The theory also proposes the treatment of "tonifying kidney and supplementing essence， harmonizing Yin and Yang， warming and supporting primordial Qi， and nourishing soma and spirit" and the representative anti-aging drugs. The article unfolds from the perspective of the concepts of natural life span， premature senility before fifty， decline， and aging and also explains the origins and connotations of premature aging. The article explains the disease mechanism of premature aging under the guidance of the essence-Qi-spirit theory of Qiluo doctrine， which is "early deprivation of kidney essence， deficiency of primordial Qi， accumulation of deficiencies into impairment， and decline and impairment of soma and spirit"， summarizes the progress of modern medical research on the treatment of premature aging and representative drugs， and finds that Bazi Bushen capsules have a precise therapeutic effect on the overall premature aging， systematic functional decline， and related diseases. The study provides theoretical basis and new ideas to solve the problems of premature aging and geriatric diseases.

Objective To explore the diagnosis and treatment strategies for elderly patients with ground-glass opacity (GGO). Methods The imaging features and postoperative pathological findings of the elderly patients with pulmonary GGO receiving surgery in our hospital from 2017 to 2019 were retrospectively analyzed. The patients were divided into an elderly patient group and a non-elderly patient group based on their age. Results Finally 575 patients were included in the study. There were 281 elderly patients, including 83 males and 198 females, with an average age of (67.0±5.3) years. There were 294 non-elderly patients, including 88 males and 206 females, with an average age of (49.1±7.3) years. Compared with the non-elderly patients, elderly GGO patients showed the following distinct clinical features: long observation time for lesions (P=0.001), high proportion of rough edges of GGO (P<0.001), significant pleural signs (P＜0.001) and bronchial signs (P＜0.001), and high proportion of type Ⅱ-Ⅳ GGO (P<0.001), lobectomy type (P=0.013), and invasive lesions reported in postoperative pathology (P<0.001). There was no statistical difference in the average hospital stay between the two groups (P=0.106). Multivariate logistic regression analysis showed that GGO diameter and GGO type were the main factors affecting the operation. Observation time, GGO diameter, GGO type and pleural signs were the main influencing factors for postoperative pathological infiltrative lesions. The cut-off value of GGO diameter in predicting infiltrating lesions was 10.5 mm in the elderly patients group. Conclusion The size and type of GGO are important factors in predicting invasive lesions and selecting surgical methods. Elderly patients with radiographic manifestations of type Ⅱ-Ⅳ GGO lesions with a diameter greater than 10.5 mm should be closely followed up.

Objective:To evaluate the effect of anterior quadratus lumborum block at the lateral supra-arcuate ligament on the postoperative pulmonary function in patients undergoing robot-assisted laparoscopic radical prostatectomy under general anesthesia.Methods:Seventy-two American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ patients, aged 50-80 yr, with body mass index of 18.5-27.9 kg/m 2, scheduled for elective robot-assisted laparoscopic radical prostatectomy under general anesthesia, were divided into 2 groups ( n=36 each) using a random number table method: control group and observation group. After induction of general anesthesia, observation group underwent anterior quadratus lumborum block at the lateral supra-arcuate ligament under ultrasound guidance, with 20 ml of 0.375% ropivacaine administered on each side. Control group only received total intravenous anesthesia. Postoperative analgesia was provided by patient-controlled intravenous analgesia until 48 h after operation, and intravenous dezocine was administered as rescue analgesic when the visual analogue scale score at rest≥4. Pulmonary function was assessed at 1 day before surgery and 1-7 days after surgery. Forced vital capacity (FVC), forced expiratory volume in 1 s (FEV 1), maximal mid-expiratory flow rate (FEF 25%-75%), and time to recovery of 80% predicted pulmonary function were recorded. Arterial blood gas analysis was performed at 1 day before surgery and 1-3 days after surgery, and SpO 2, PaO 2 and PaCO 2 were recorded. The consumption of intraoperative remifentanil, effective pressing times of patient-controlled analgesia, and the number of patients required rescue analgesia were recorded. Postoperative pulmonary complications within 7 days after operation and re-hospitalization within 30 days were recorded. The time to first flatus, postoperative length of hospital stay and occurrence of adverse reactions (dizziness, nausea, vomiting) within 3 days after surgery were also recorded. Results:Compared with control group, FVC, FEV 1 and FEF 25%-75% were significantly increased postoperatively, the time to recovery of 80% FVC, FEV 1 and FEF 25%-75% was shortened, postoperative SpO 2 and PaO 2 were increased, postoperative PaCO 2 was decreased, the consumption of intraoperative remifentanil, effective pressing times of patient-controlled analgesia, and the number of patients required rescue analgesia were reduced, the postoperative time to first flatus and length of hospital stay were shortened, and the incidence of adverse reactions and pulmonary complications was decreased ( P<0.05). Conclusions:Anterior quadratus lumborum block at the lateral supra-arcuate ligament can improve postoperative pulmonary function, reduce adverse reactions, and promote early recovery for the patients undergoing robot-assisted laparoscopic radical prostatectomy under general anesthesia.

Nonalcoholic fatty liver disease(NAFLD)is a metabolic liver disease that ranges from relatively benign hepatic steatosis to nonalcoholic steatohepatitis(NASH).NASH is characterized by persistent liver damage,inflammation,and fibrosis which significantly increases the risk of end-stage liver diseases,such as liver cirrhosis and hepatocellular carcinoma.The pathogenesis of NAFLD/NASH is not yet fully understood,but its recent epigenetic advances have provided new insights into the mechanisms of this disease.This review summarized recent progress in this area which has laid a solid foundation for elucidating the pathogenesis of NAFLD and provides potential targets for early detection,diagnosis,and treatment of this disease.

Perimenopausal syndrome （MPS）， a common endocrine system disease， is one of the diseases responding specifically to traditional Chinese medicine （TCM）. The China Association of Chinese Medicine organized experts in endocrinology， gynecology， and interdisciplinary fields of both Western and Chinese medicine to discuss the advantages and challenges of diagnosing and treating MPS with Western medicine， TCM， and integrative medicine. Experts at the conference believe that MPS is initiated by estrogen decline and rooted in deficiency， with the pathogenesis being imbalance between Yin and Yang in the kidney. The hormone replacement therapy in Western medicine for menopause can rapidly alleviate related symptoms by quickly restoring the estrogen level and timely detect and delay complications of menopause， whereas such a therapy has certain risks， necessitating close monitoring of adverse reactions. Moreover， the various contraindications and precautions limit the clinical application of the hormone replacement therapy. TCM has advantages in synergistically alleviating symptoms such as hot flashes， sweating， sleep disorders， and emotional abnormalities of MPS without causing obvious adverse reactions. However， its efficacy is slower than the hormone replacement therapy， and the TCM evidence for preventing and treating complications of menopause remains unclear. Three suggestions were proposed for the future development of both Western and TCM for ameliorating MPS. First， an integrated diagnosis and treatment system for MPS with both Western and Chinese medicine should be established. Second， high-quality evidence-based interventions for MPS should be developed with TCM alone or in combination with Western medicine. Third， efforts should be made to promote the new TCM drug development and the interdisciplinary cooperation for treating MPS.

ObjectiveTo investigate the effect of mucin 1 (MUC1) on the proliferation and apoptosis of nasopharyngeal carcinoma (NPC) and its regulatory mechanism. MethodsThe 60 NPC and paired para-cancer normal tissues were collected from October 2020 to July 2021 in Quanzhou First Hospital. The expression of MUC1 was measured by real-time quantitative PCR (qPCR) in the patients with PNC. The 5-8F and HNE1 cells were transfected with siRNA control (si-control) or siRNA targeting MUC1 (si-MUC1). Cell proliferation was analyzed by cell counting kit-8 and colony formation assay, and apoptosis was analyzed by flow cytometry analysis in the 5-8F and HNE1 cells. The qPCR and ELISA were executed to analyze the levels of TNF-α and IL-6. Western blot was performed to measure the expression of MUC1, NF-кB and apoptosis-related proteins (Bax and Bcl-2). ResultsThe expression of MUC1 was up-regulated in the NPC tissues, and NPC patients with the high MUC1 expression were inclined to EBV infection, growth and metastasis of NPC. Loss of MUC1 restrained malignant features, including the proliferation and apoptosis, downregulated the expression of p-IкB、p-P65 and Bcl-2 and upregulated the expression of Bax in the NPC cells. ConclusionDownregulation of MUC1 restrained biological characteristics of malignancy, including cell proliferation and apoptosis, by inactivating NF-κB signaling pathway in NPC.

Objective To investigate the effect of ultrasound-guided anterior quadratus lumborum block at lateral supra-arcuate ligament on postoperative analgesia and inflammation response in elderly patients undergoing robot-assisted laparoscopic radical prostatectomy.Methods A total of 60 elderly patients who had undergone robot-assisted laparoscopic radical prostatectomy from June 2022 to June 2023 were randomly divided into a group of ultra-sound-guided anterior quadratus lumborum block at lateral supra-arcuate ligament combined with general anesthesia(observation group,n = 30)and a general anesthesia group(control group,n = 30).Both groups received patient-controlled intravenous analgesia after surgery.The first compression time of an analgesic pump and the numbers of effective compression and remedial analgesia were recorded.The VAS scores at postsurgical hours 2,12,24,and 48 during rest and coughing were recorded.Interleukin-6(IL-6)and systemic immunoinflammatory index(SII)at one day before surgery and two hours,one day and three days after surgery were recorded.Anal exhaust time,length of postoperative hospital stay and occurrence of adverse reactions were recorded.Results The observation group,as compared with the control group,had significantly longer first compression time of an analgesic pump and had fewer numbers of effective compressions and remedial analgesic administrations(P<0.05).The VAS scores during rest and coughing in the observation group were lower than those in the control group at postsurgical hours 2,12,24,and 48(P<0.05).As compared with one day before surgery,both IL-6 and SII in the two groups increased at 2 hours,1,and 3 days after surgery,but the changes in the observation group were lower than those in the control group(P<0.05).As compared with the control group,the observation group had shorter anal exhaust time and length of postoperative hospital stay,and a lower incidence of adverse reactions(P<0.05).Conclusions Ultrasound-guided anterior quadratus lumborum block at lateral supra-arcuate ligament can provide better postoperative analgesia,reduce inflammatory response and accelerate postoperative recovery in elderly patients undergoing robot-assisted laparoscopic radical prostatectomy.
