Osteoporosis is a common senile bone metabolism disease， clinically characterized by decreased bone mass， destruction of bone microstructure， increased bone fragility， and easy fracture. It tends to occur in the elderly and postmenopausal women， seriously threatening the quality of life and physical and mental health of the elderly. At present， the treatment of osteoporosis is mainly based on oral western medicines， such as calcium， Vitamin D， and bisphosphonates. Still， there are drawbacks such as a long medication cycle and many adverse reactions. In recent years， due to the advantages of multi-component， multi-pathway， and multi-target， some traditional Chinese medicines and effective ingredients can regulate the osteogenic and osteoclastic differentiation process in both directions and are widely used in the prevention and treatment of osteoporosis. Hippophae rhamnoides is a commonly used herbal medicine， and its fruits are rich in flavonoids， polyphenols， fatty acids， vitamins， and trace elements， which have been proven to have a good anti-osteoporosis effect. Isorhamnetin is the main effective ingredient of Hippophae rhamnoides fruits， which has many pharmacological effects such as anti-inflammation， anti-oxidative stress， anti-aging， and anti-tumor. Studies have shown that isorhamnetin can participate in the regulation of bone metabolism and has a good anti-osteoporosis effect. However， the pharmacological effects and related mechanisms of isorhamnetin against osteoporosis have not been systematically summarized. Therefore， this paper reviewed the pharmacological effects and related mechanisms of isorhamnetin against osteoporosis by referring to relevant literature to provide more basis for the development and application of isorhamnetin.

Objective To explore the clinical efficacy of arc-edge needle therapy based on Zaodian theory in the treatment of refractory tennis elbow.Methods 64 patients with refractory tennis elbow were collected and randomly divided into a control group and an observation group using a random number table method.Among them,32 cases in the control group were treated with local pain point injection.32 patients in the observation group were treated with arc-edge needle therapy once a week,with two treatments per group.The Number rating scale(NRS)Mayo,elbow joint performance score(MEPS)and Disabilities of the arm,shoulder and hand(DASH)score were recorded and compared between the two groups before treatment and at 1,2,4 and 24 weeks of follow-up after treatment,disease efficacy score(WDES)at 24 weeks of follow-up.Results During the treat-ment process,neither group of patients experienced serious adverse reactions.At each stage after treatment,two groups of NRS MEPS,DASH,and WDES at 24 weeks of follow-up all improved compared to before treatment.After one week of treatment,there was no statistically significant difference in NRS scores between the two groups(P>0.05).At follow-up visits at weeks 2,4,and 24,the NRS scores in the observation group were lower than those in the control group.After 1,2,4,and 24 weeks of follow-up after treatment,the DASH score was lower in the observation group than in the control group,and the MEPS score was higher in the observation group than in the control group,with statistically significant differences(P<0.05).After 24 weeks of treatment,the WDES of the observation group was better than that of the control group,and the difference was statistically significant(P<0.05).Conclusion Local pain point injection and arc-edge Zaodian release can alleviate pain and improve elbow joint function in the early stage of refractory tennis elbow.However,the long-term effect of local pain point injection treatment is not good,and the treatment effect of the observation group gradually improves.

Objective To explore the clinical value of preoperative Glasgow-Blatchford score(GBS)and AIMS65 score in predicting the prognosis of patients with non-variceal upper gastrointestinal bleeding after receiving interventional treatment.Methods The clinical data of 59 patients with non-variceal upper gastrointestinal bleeding,who received transcatheter arterial embolization(TAE)at the Department of Interventional Vascular Surgery,Shanghai Tenth People's Hospital of China between 2018 and 2021,were collected.The clinical value of GBS and AIMS65 score in predicting patient's outcome was analyzed.Results With the preoperative GBS and AIMS65 scores increasing,the mortality also increased.Compared with AIMS65 score(AUC=0.630,0.95％CI:0.494-0.752),GBS(AUC=0.823,95％CI:0.702-0.910)had a higher predictive value for postoperative in-hospital death in patients with non-variceal upper gastrointestinal bleeding after receiving interventional treatment.With a GBS cutoff＞9 points,the Youden index for predicting in-hospital death was 0.54.Conclusion In predicting the postoperative in-hospital death for patients with non-variceal upper gastrointestinal bleeding after receiving TAE,the clinical value of the preoperative GBS score is higher than that of AIMS65 score.

Objective:To investigate the correlation between 25-hydroxyvitamin D3 (25 (OH) D3), insulin-like growth factor 1 (IGF-1) and glycolipid metabolism in patients with diabetes 2 mellitus (T2DM), as well as their predictive value in retinopathy.Methods:A total of 120 T2DM patients admitted to Linyi Central Hospital of Shandong Province from Oct. 2020 to Oct.r 2023 were selected as the study objects (defined as the study group). Another 120 healthy volunteers who underwent physical examination in our hospital during the same period were selected as the control group. Serum 25 (OH) D3, IGF-1, fasting blood glucose (FBG), 2 h plasma glucose (2 hPG) ) and lipid levels (triglycerides) were compared between the two groups. The levels of TG, total cholesterol (TC) and serum 25 (OH) D3 and IGF-1 were analyzed by Pearson correlation analysis. At the same time, the patients in the study group were divided into diabetic group with retinopathy (DR Group, 40 cases) and non-retinopathy group (NDR group, 80 cases) according to the status of retinopathy. Multivariate analysis was used to analyze the risk factors affecting the occurrence of retinopathy in T2DM patients, and receiver operating characteristic (ROC) curve was drawn to analyze the predictive value of serum 25 (OH) D3 and IGF-1 levels in the occurrence of retinopathy in T2DM patients.Results:The level of serum 25 (OH) D3 was (36.15±4.25) nmol/L in the study group, lower than that in the control group (51.24±5.32) nmol/L ( P<0.05), and the level of IGF-1 was (30.26±4.52) mg/L was in the study group, higher than that in the control group ( P<0.05). The levels of FBG, 2 hPG, TG and TC in the study group were (8.67±2.52) mmol/L, (11.36±2.43) mmol/L, (2.05±0.72) mmol/L, (5.05±1.54) mmol/L respectively, higher than those in the control group [ (5.02±0.42) mmol/L, (6.32±0.54) mmol/L, (1.21±0.32) mmol/L, (3.42±0.68) mmol/L] ( P<0.05). Pearson correlation analysis showed that serum 25 (OH) D3 levels were negatively correlated with FBG, 2 hPG, TG and TC levels in T2DM patients ( r=-0.762, -0.782, -0.736, -0.721, P<0.05). Serum IGF-1 levels were positively correlated with the levels of FBG, 2 hPG, TG and TC in T2DM patients ( r=0.741, 0.756, 0.715, 0.698, P<0.05). Family history of diabetes in DR group, FBG, 2 hPG, TG, TC, IGF-1 levels was 35.00%, (9.31±2.49) mmol/L, (12.52±2.34) mmol/L, (2.76±0.61) mmol/L, (5.92±1.42) mmol/L, (37.89±4.41) mg/L respectively, higher than those in NDR group [16.25%, (8.35±2.15) mmol/L, (10.78±1.75) mmol/L, (1.69±0.52) mmol/L, (4.62±1.31) mmol/L, (26.45±4.06) mg/L] ( P<0.05). 25 (OH) D3 in DR group was (30.21±3.51) nmol/L, lower than that in NDR group (39.12±3.85) nmol/L ( P<0.05). Logistic regression analysis showed that family history of diabetes mellitus, duration of diabetes mellitus, 25 (OH) D3, IGF-1, FBG, 2hPG, TG and TC levels were all risk factors for the occurrence of retinopathy in elderly T2DM patients ( P<0.05). ROC curve analysis showed that AUC and sensitivity of 25 (OH) D3 and IGF-1 combined to predict retinopathy in elderly T2DM patients were 0.854 and 92.50%, respectively, higher than that of 25 (OH) D3 and IGF-1 alone ( P<0.05) . Conclusion:Serum 25 (OH) D3 and IGF-1 levels are abnormally expressed in elderly patients with T2DM, and there is a close relationship between glucose and lipid metabolism in elderly patients with T2DM, and the combined detection of these indicators has a higher predictive value for the occurrence of DR In elderly patients with T2DM.

With the aging of population, the elderly (≥65 years old) cancer patients have become one of the main populations for cancer care. For inoperable locally advanced head and neck squamous carcinomas, cisplatin-based concurrent chemoradiotherapy is the first-line choice. Several large clinical studies have shown that patients under 70 years of age can still benefit from concurrent chemoradiotherapy, while it should be cautious to apply chemotherapy to patients aged 70-80 years. For elderly patients who are intolerant to cisplatin, carboplatin or other regimens with less gastrointestinal and renal toxicity should be considered. Although anti-epidermal growth factor receptor (EGFR) monoclonal antibodies combined with radiotherapy has been proved to be more effective than radiotherapy alone in total patient population, age-subgroup analysis showed limited benefit in elderly patients. The safety of immune checkpoint inhibitors in elderly patients has been validated and those with high programmed death ligand-1 (PD-L1) expression may benefit from concurrent or neoadjuvant immunotherapy, however, high-level evidence is still lacking. For patients older than 80 years, radiotherapy alone may be superior to concurrent chemoradiotherapy, and hypofractionated radiotherapy for palliative purposes can be safely used in this population.

Hepatosteatosis is characterized by abnormal accumulation of triglycerides(TG),leading to prolonged and chronic inflammatory infiltration.To date,there is still a lack of effective and economical therapies for hepatosteatosis.Oridonin(ORI)is a major bioactive component extracted from the traditional Chinese medicinal herb Rabdosia rubescens.In this paper,we showed that ORI exerted significant protective ef-fects against hepatic steatosis,inflammation and fibrosis,which was dependent on LXRα signaling.It is reported that LXRα regulated lipid homeostasis between triglyceride(TG)and phosphatidylethanol-amine(PE)by promoting ATCL and EPT1 expression.Therefore,we implemented the lipidomic strategy and luciferase reporter assay to verify that ORI contributed to the homeostasis of lipids via the regulation of the ATGL gene associated with TG hydrolysis and the EPT1 gene related to PE synthesis in a LXRα-dependent manner,and the results showed the TG reduction and PE elevation.In detail,hepatic TG overload and lipotoxicity were reversed after ORI treatment by modulating the ATCL and EPT1 genes,respectively.Taken together,the data provide mechanistic insights to explain the bioactivity of ORI in attenuating TG accumulation and cytotoxicity and introduce exciting opportunities for developing novel natural activators of the LXRα-ATGL/EPT1 axis for pharmacologically treating hepatosteatosis and metabolic disorders.

Radiotherapy is an essential part of comprehensive treatment, as well as a radical treatment for head and neck cancer (HNC). The COVID-19 has continued so far, imposing a great impact on cancer care. Since conventional fractionated radiotherapy (CFRT, 2 Gy/F) requires as long as more than six weeks of treatment time, a huge challenge for epidemic control is created for both hospitals and patients. Hypofractionated radiotherapy (Hypo-RT) may be more suitable than CFRT for patients during pandemic by increasing the fraction size, thus reducing fraction number and treatment duration. Early studies have explored the application of Hypo-RT in HNC in palliative setting, which partially proved its safety and effectiveness. Recently, the efforts have been made in definitive treatment using hypofractionated regimen, as well as its combination with systemic treatment and immunotherapy. Indeed, regarding the pandemic of COVID-19, Hypo-RT has been recommended by several expert consensus in the HNC. In this review, relevant research progress was summarized and clinical implication of Hypo-RT in COVID-19 pandemic era was discussed.

Objective:To summarize experience and effect of the stylized operation step in the neck endoscopic thyroidectomy for papillary thyroid microcarcinoma (PTMC).Methods:The clinical data of 51 patients who underwent transthoracic breast approach scarless neck endoscopic thyroidectomy (SET) from January 2018 to September 2019 in Tungwah Hospital Affiliated to Sun Yat-sen University were retrospectively analyzed. The operative procedure used stylized operation steps: establishment of operating space, three-step method thyroidectomy, central lymph node dissection (CLND), close operating space.Results:Among 51 patients, 25 cases underwent unilateral thyroidectomy plus isthmic resection, 26 cases underwent total/near-total thyroidectomy, and 16 cases underwent preventive CLND. The recurrent laryngeal nerve (RLN) was exposed in all 51 cases, the external branches of the superior laryngeal nerve (EBSLN) was exposed in 35 cases, no procedure was converted into open neck incision thyroidectomy. Forty-two cases were followed up, 2 cases had postoperative hoarseness and unilateral recurrent laryngeal nerve paralysis, which were recovered 55 and 75 d after operation respectively. There was no bucking, voice blunt or permanent low calcium. One patient had abnormal sensation of neck skin after operation, and recovered gradually 3 months after operation.Conclusions:The stylized operation step in the SET can increase safety of surgery.

Hepatic ischemia-reperfusion injury (HIRI) is the main cause of liver damage and even multiple organ failure after complex liver surgery.When liver ischemia reperfusion occurs,the non-coding RNAs in the liver tissue is dysregulated and part of the non-coding RNAs with abnormal expression is involved in HIRI regulation.Non-coding RNAs to may be the intervention target for reducing HIRI.This article summarized the types and related functions of non-coding RNAs,the role of different non-coding RNAs in HIRI,and the interconnections between various non-coding RNAs in HIRI.
