The occurrence of diabetes mellitus （DM） is closely related to insulin resistance and islet β cell dysfunction. Modern studies have found that macrophages are widely present in the liver，fat，skeletal muscle，islets， and other tissues and organs. Macrophage M1/M2 polarization plays an important role in the occurrence and development of diabetes mellitus and its related complications by intervening in inflammatory response，improving insulin resistance，and promoting tissue repair. Most of the traditional Chinese medicines that regulate the activation and polarization of macrophages are Qi-replenishing and Yin-nourishing，heat-clearing， and detoxicating medicinal，which are consistent with the etiology and pathogenesis of diabetes and its related complications. Therefore，by summarizing the mechanisms between macrophage activation，polarization， and insulin resistance in various tissues，this paper reviewed traditional Chinese medicine and its effective components and compounds in improving diabetes mellitus and its related complications through multi-channel regulation of macrophage polarization and regulation of M1/M2 ratio，providing references for the future treatment of DM and its related complications with traditional Chinese medicine.

OBJECTIVE To evaluate the efficacy and safety of high-dose ilaprazole combined with amoxicillin for newly diagnosed elderly patients with Helicobacter pylori （Hp） infection， and analyze independent risk factors for failure of Hp infection eradication treatment. METHODS Totally 200 cases of newly diagnosed elderly patients with Hp infection in Xinxiang Central Hospital from August 1， 2021 to December 1， 2024 were selected and randomly divided into control group and study group， with 100 cases in each group. The control group was treated with classic quadruple therapy regimen （Amoxicillin capsules+ Clarithromycin tablets+Bismuth potassium citrate tablets+Ilaprazole enteric-coated tablets）. The study group was treated with high- dose Ilaprazole enteric-coated tablets+Amoxicillin capsules. All patients were administered medication for 2 weeks. Hp eradication rates in the two groups were compared using intention-to-treat （ITT） and per-protocol （PP） analyses. The incidence of adverse reactions in both groups was also recorded. The multiple-factor Logistic regression analysis was used to identify independent risk factors for failure of Hp infection eradication treatment. RESULTS In ITT and PP analyses， there was no significant difference of Hp eradication rates between the two groups （P＞0.05）. There was no significant difference in incidence of mild to moderate adverse reactions between the two groups （P＞0.05）. BMI ≤18.5 kg/m2， BMI ＞23.9 kg/m2， rural residence， concomitant diabetes and concomitant heart disease were identified as independent risk factors influencing the failure of Hp infection eradication treatment （P＜0.05）. CONCLUSIONS The efficacy and safety of high-dose ilaprazole combined with amoxicillin are comparable to classic quadruple therapy regimen in treating newly diagnosed elderly patients with Hp infection. Independent risk factors influencing the failure of Hp infection eradication treatment include BMI ≤18.5 kg/m2， BMI ＞23.9 kg/m2， rural residence， concomitant diabetes and concomitant heart disease.

The theory of "linkage between spleen and small intestine" has been put forward by doctors as early as the Ming dynasty. In traditional Chinese medicine， the spleen and small intestine cooperate and work together physiologically， and they are also closely related and interact with each other pathologically. The spleen governs transportation and transformation， which involves the function of the small intestine in transforming water and grain. The small intestine， governing the receiving and transformation of substances， depends on the normal transportation of the spleen. At the same time， it provides guarantee for the spleen to transform Qi and generate blood as well as ascend lucidity and descend turbidity. The dysfunction of spleen in transportation is closely related to the dysfunction of small intestine. The stability of intestinal microecology necessitates the normal functioning of the spleen. When the original balance of intestinal flora is disturbed， the spleen functioning will be affected. This study explored the pathogenesis and treatment of diabetes based on the physiological functions of the spleen and small intestine and the Western medicine targets of "nutrients-intestinal flora". According to modern medicine， nutrients are essential to maintain the normal physiological activities of the human body. Proper intake of nutrients can affect the absorption and metabolism of the human body for nutrients by regulating the composition and function of intestinal flora， so as to prevent the occurrence of diabetes. The imbalance of intestinal flora which harbors rich microorganisms may lead to the disturbance of energy metabolism and the dysfunction of the immune system， eventually leading to diabetes. As a metabolic disease， diabetes is closely related to the imbalance of intestinal flora and nutrient intake. Based on the theory of "linkage between spleen and small intestine"， this paper discusses the relationship between spleen and small intestine. Furthermore， this paper discusses the correlation between "spleen-small intestine" and "nutrients-intestinal flora" by reviewing the latest progress in modern medicine and clinical research， aiming to provide a theoretical basis and new ideas for the clinical prevention and treatment of type 2 diabetes mellitus.

BACKGROUND:Increasing studies have shown that autophagy plays an important role in the treatment of osteoarthritis,and moderate autophagy can preserve the normal physiological function of osteoarticular chondrocytes.Traditional Chinese medicine(TCM)monomers can target and modulate autophagy to treat osteoarthritis,and their characteristics such as single components,clear efficacy,low price,and easy availability have obvious benefits in the treatment of osteoarthritis.OBJECTIVE:To review the effects of TCM monomers on the targeted regulation of autophagy in the treatment of osteoarthritis and the research progress,with a view to laying a foundation for the treatment of osteoarthritis and even other bone metabolic diseases.METHODS:Relevant literature published from January 2012 to October 2022 was retrieved in PubMed,Web of Science,CNKI,and WanFang using the keywords of"traditional Chinese medicine,Chinese herbal monomer,autophagy,osteoarthritis"in English and Chinese.Inclusion and exclusion criteria were developed,and 63 relevant articles were finally included by screening through reading the title,abstract,and full-text content.RESULTS AND CONCLUSION:TCM monomers can treat osteoarthritis by targeting autophagy to inhibit chondrocyte apoptosis,protect cartilage extracellular matrix,reduce inflammation and antagonize oxidative stress injury.Different TCM monomers can regulate autophagy in the same way,and the same TCM monomers can affect autophagy in different ways.The combination of multiple monomers and the multi-target and multi-pathway regulation of autophagy by TCM monomers remain to be explored.The regulation of autophagy by TCM monomers can provide new ideas and strategies for the prevention and treatment of osteoarthritis.Moderate regulation of autophagy by TCM monomers to keep the autophagic flux unimpeded may be the key to treating osteoarthritis.

BACKGROUND:More and more studies have shown that oxidative stress should play an important role in the treatment of osteoporosis.Oxidative stress should cause the accumulation of oxidation activity,which will damage bone-related cells.Finally,it causes the imbalance of bone resorption and bone formation,resulting in a decrease in bone volume and the destruction of the slight structure.Research in recent years has found that some natural products can regulate oxidative stress to treat osteoporosis.The characteristics of extensive sources and small side effects have obvious advantages in the treatment of osteoporosis,and the efficacy is objective. OBJECTIVE:To discuss the mechanism of natural product regulation of oxidation stress in treatment of osteoporosis,conduct a review based on the latest related research progress,provide reference and ideas for more natural products to treat osteoporosis in the future,and provide data support for the clinical application of natural compounds in the treatment of osteoporosis. METHODS:"oxidative stress,free radical,antioxidant,phytotherapy,plant extracts,medicinal plants,herbal medicine,osteoporosis,bone density,bone loss"were used as the keywords in PubMed,Web of Science,Embase,Cochrane,VIP,CBM,WanFang,and CNKI databases to search relevant articles published from January 2010 to February 2023.Inclusion and exclusion criteria were developed,and 64 relevant articles were selected by reading titles,abstracts,and full texts. RESULTS AND CONCLUSION:(1)Some natural products have antioxidant effects and can regulate osteogenic differentiation,osteoblast bone matrix mineralization,osteoclast-mediated bone resorption,proliferation,differentiation,activity,and apoptosis of bone-related cells by improving oxidative stress,thus affecting bone metabolism.(2)These natural products with antioxidant effects play a role in treating osteoporosis by improving bone remodeling balance.(3)The research on the combination of a variety of natural products to improve osteoporosis remains to be explored.(4)The use of natural products to regulate oxidative stress may become a powerful weapon for the clinical treatment of osteoporosis in the future.

Objective:To investigate the clinicopathological factors and clinical significance of (micro)metastasis in No.12b lymph node in patients with gastric antrum cancer.Methods:This was a retrospective cohort study of data of 242 patients with gastric adenocarcinoma without distant metastasis, complete follow-up data, and no preoperative anti-tumor therapy or history of other malignancies. All study patients had undergone radical gastrectomy (at least D2 radical range) + No.12b lymph node dissection in the Department of Gastric Surgery of Liaoning Cancer Hospital from January 2007 to December 2012. Immunohistochemical staining with antibody CK8/18 was used to detect micrometastasis to lymph nodes. Patients with positive findings on hematoxylin and eosin stained specimens and/or CK8/18 positivity in No.12b lymph node were diagnosed as having No.12b (micro)metastasis and included in the No.12b positive group. All other patients were classified as 12b negative. We investigated the impact of No.12b (micro)metastasis by comparing the clinicopathological characteristics and recurrence free survival (RFS) of these two groups of patients and subjecting possible risk factors to statistical analysis.Results:Traditional hematoxylin-eosin staining showed that 15/242 patients were positive for No.12b lymph nodes and 227 were negative. A total of 241 negative No. 12b lymph nodes were detected. Immunohistochemical testing revealed that seven of these 241 No.12b lymph nodes (2.9%) were positive for micrometastasis. A further seven positive nodes were identified among the 227 nodes (3.1%) that had been evaluated as negative on hematoxylin–eosin-stained sections. Thus, 22 /242 patients' (9.1%) No.12b nodes were positive for micrometastases, the remaining 220 (90.9%) being negative. Factor analysis showed that No.12b lymph node (micro) metastasis is associated with more severe invasion of the gastric serosa (HR=3.873, 95%CI: 1.676-21.643, P=0.006), T3 stage (HR=1.615, 95%CI: 1.113-1.867, P=0.045), higher N stage (HR=1.768, 95%CI: 1.187-5.654, P=0.019), phase III of TNM stage (HR=2.129, 95%CI: 1.102-3.475, P=0.046), and lymph node metastasis in the No.1/No.8a/No.12a groups (HR=0.451, 95%CI: 0.121-0.552, P=0.035; HR=0.645, 95%CI:0.071-0.886, P=0.032; HR=1.512, 95%CI: 1.381-2.100, P=0.029, respectively). Survival analysis showed that the 5-year RFS of patients in the No.12b positive group was worse than that of those in the No.12b negative group (18.2% vs. 34.5%, P<0.001). Independent predictors of RFS were poorer differentiation of the primary tumor (HR=0.528, 95%CI:0.288-0.969, P=0.039), more severe serous invasion (HR=1.262, 95%CI:1.039-1.534, P=0.019), higher T/N/TNM stage (HR=4.880, 95%CI: 1.909-12.476, P<0.001; HR=2.332, 95%CI: 1.640-3.317, P<0.001; HR=0.139, 95%CI: 0.027-0.713, P=0.018, respectively), and lymph node metastasis in the No.12a/No.12b group(HR=0.698, 95%CI:0.518-0.941, P=0.018; HR=0.341, 95%CI:0.154-0.758, P=0.008, respectively). Conclusion:Detection of micrometastasis can improve the rate of positive lymph nodes. In patients with gastric antrum cancer, dissection of group No.12b lymph nodes may improve the prognosis of those with intraoperative evidence of tumor invasion into the serosa, more than two lymph node metastases, and suspicious lymph nodes in groups No.1 / No.8a / 12a.

Objective:To explore the application effect of Bandura's "model theory" in the teaching of internal medicine nursing.Methods:Based on Bandura's "model theory", the micro-video of nursing model expert was made and integrated into the teaching of internal medicine nursing. Using the convenient sampling method, a total of 81 students from 2 classes of grade 2019 nursing vocational college in School of Health and Social Care of Shanghai Urban Construction Vocational College were selected as the research objects. The students were divided into the control group ( n=42) and the study group ( n=39) by drawing lots. The students in the study group received micro video case teaching from internal medicine nursing model experts, while students in the control group received traditional PPT teaching in internal medicine nursing. After the implementation of the teaching, the implementation effect of the course was evaluated by using the Nurses' Professional Identity Rating Scale and programme performance. Results:After the teaching, the programme performance of the study group was (68.36±10.35), which was higher than (55.79±14.17) of the control group, and the difference was statistically significant ( P<0.01). After the teaching, the total score and 5 dimensions of Nurses' Professional Identity Rating Scale of nurses in the study group were higher than those in the control group, and the differences were statistically significant ( P<0.05) . Conclusions:The application of Bandura's "model theory" in the teaching of internal medicine nursing can effectively improve the programme performance and professional identity of nursing students in higher vocational colleges.

Objective:To explore any effect of upper limb swing training guided by rhythmic auditory stimulation (RAS) on the walking ability of stroke survivors.Methods:Eighty stroke survivors were randomly divided into an observation group and a control group. Both groups received conventional rehabilitation treatment, including neuromuscular facilitation, muscle strength training, balance training and gait training, but the observation group was additionally provided with RAS-guided upper limb swing training for 20min once a day, 5d per week for 6 weeks. Before and after the intervention, balance and lower limb function were quantified in both groups using Holden′s walking function classification, the Fugl-Meyer lower extremity motor function scale (FMA-LE), the Berg Balance Scale (BBS) and the 10m walk test (10MWT). Limits of stability were also quantified.Results:After the treatment, the average Holden, FMA-LE and BBS scores, as well as the average 10MWT time were significantly better in the observation group than in the control group. The average stability limits and their maintenance were also superior.Conclusion:RAS-guided upper limb swing training can improve the gait, walking ability, walking stability, walking speed and balance of stroke survivors.
