Objective To longitudinally investigate the characteristics of postoperative weight changes in patients with esophageal cancer and analyze its influencing factors, which can provide certain guidance for nutritional intervention in patients with esophageal cancer. Methods Patients with esophageal cancer who underwent surgical treatment at the Sichuan Cancer Hospital from December 2020 to February 2022 were prospectively included. The general information questionnaire and body composition analyzer were used to longitudinally investigate the patients’ weight and body composition before surgery (T0), 1 month after surgery (T1), 3 months after surgery (T2) and 6 months after surgery (T3), and the change characteristics were analyzed. The generalized estimating equation was used to analyze the influencing factors for postoperative weight changes in patients with esophageal cancer. Results A total of 130 patients were enrolled, including 110 males and 20 females, aged 42-79 (63.33±8.16) years. The weight and body composition of patients with esophageal cancer showed a continuous slow downward trend within 6 months after surgery. The weight loss rate of patients at 1, 3, and 6 months after surgery was 5.10%, 7.76%, and 9.86%, respectively. The analysis results of the influencing factors for postoperative weight showed that patients with the following characteristics had more weight loss: female (β=−7.703, P=0.001), ≥60 years (β=−3.657, P=0.010), smoking (β=4.622, P=0.010), low tumor differentiation degree (β=4.314, P=0.039), and high frequency of eating (β=−3.400, P=0.008). Conclusion Weight loss is an important health problem for patients with esophageal cancer after surgery, and patients have a continuous downward trend in weight within 6 months after surgery. Medical staff should pay special attention to the patients who are female, ≥60 years, having smoking history and low tumor differentiation degree.

"Dietary inquiry" is a core component of the diagnostic system in traditional Chinese medicine （TCM）， which can be divided into three aspects including appetite， eating capacity， and food preference. Abnormalities in appetite are mainly attributed to dysfunction of the mind and impaired regulatory mechanisms. Clinical inquiry should focus on hunger sensation and the willingness to eat voluntarily. Treatment should aim to soothe the liver， regulate the spleen， nourish and calm the mind. Abnormalities in eating capacity are related to disorders of qi movement and structural dysfunction， for which inquiry should focus on whether food descends smoothly and on postprandial reactions， and the corresponding treatment is descending qi， relieving fullness， and promoting bowel movement and digestion. Abnormalities in food preference arise from damage caused by the five flavors and imbalance of visceral qi， for which inquiry should focus on dietary preferences and whether eating brings comfort. It is important to distinguish between "stomach preference" and "oral preference"， and treatment should carefully differentiate flavor tendencies and correct imbalances through appropriate dietary flavors. By refining the content of dietary inquiry， this study explores how different dimensions of eating status reflect the holistic concept and syndrome differentiation-based treatment in TCM， providing a reference for the clinical diagnosis and treatment of spleen and stomach diseases and related disorders.

ObjectiveTo observe the effects of modified Chaihu Shugansan on the calmodulin-dependent protein kinase Ⅱ（CaMKⅡ）/cAMP-response element binding protein （CREB） signaling pathway in the hippocampus and heart tissue of a rat model with myocardial ischemia and depression and explore the mechanism by which this formula prevents and treats coronary heart disease combined with depression. MethodsThe model of myocardial ischemia combined with depression was established by high-fat diet， intraperitoneal injection of isoproterenol （ISO）， and chronic unpredictable mild stress （CUMS）. A total of 108 SD male rats were randomly divided into normal group， model group， high （23.4 g·kg^-1）， medium （11.7 g·kg^-1）， and low （5.85 g·kg^-1） dose groups of modified Chaihu Shugansan， CaMKⅡ inhibitor （KN93） group， and KN93 + high， medium， and low dose groups of modified Chaihu Shugansan， with 12 rats in each group. From the first day of modeling to the end of modeling， drugs were administered once a day. In the seventh and eighth weeks， the KN93 group and the KN93 + high， medium， and low dose groups of modified Chaihu Shugansan were intraperitoneally injected with KN93 three times weekly. At the end of the eighth week， behavioral tests including sucrose preference， open field， and elevated plus maze were conducted. Electrocardiogram （ECG） lead Ⅱ changes were observed in each group of rats， and hematoxylin-eosin （HE） staining was performed to observe changes in heart tissue. Serum levels of triglycerides （TG）， total cholesterol （TC）， high-density lipoprotein （HDL）， low-density lipoprotein （LDL）， and lactate dehydrogenase （LDH） were measured by using an enzyme-labeled instrument. Creatine kinase （CK） and creatine kinase-MB （CK-MB） were detected by ultraviolet spectrophotometry， while serum monocyte chemoattractant protein-1 （MCP-1） was measured by enzyme-linked immunosorbent assay （ELISA）. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to detect mRNA expression of CaMKⅡ and CREB in hippocampal and heart tissue， and Western blot was performed to assess protein expression of CaMKⅡ， phosphorylated （p）-CaMKⅡ， CREB， and p-CREB. ResultsCompared to the normal group， the model group showed significant reductions in sucrose preference rate， total activity distance in the open field， number of entries into the center area of the open field， and percentage of entries into the open arms of the elevated plus maze （P<0.01）. The ECG showed ST-segment elevation， and HE staining showed serious degeneration of myocardial fibers， disordered arrangement， and infiltration of a large number of inflammatory cells. In addition， serum TC and LDL levels increased （P<0.01）， and HDL level decreased （P<0.01）. CK， CK-MB， LDH， and MCP-1 levels significantly increased （P<0.05， P<0.01）. The mRNA expression of CaMKⅡ and CREB and the protein expression of p-CaMKⅡ and p-CREB decreased in the hippocampal tissue （P<0.05， P<0.01）， but those increased in the heart tissue （P<0.01）. Compared to the model group， the high， medium， and low dose groups of modified Chaihu Shugansan showed improvements in these abnormalities. The KN93 group had reduced sucrose preference， total activity distance in the open field， number of entries into the center area of the open field， and percentage of entries into the open arms of the elevated plus maze （P<0.01）， as well as decreased serum CK， CK-MB， LDH， and MCP-1 levels （P<0.05， P<0.01）. KN93 also reduced ST-segment elevation， alleviated the degeneration degree of myocardial fibrosis， and lowered inflammatory cell infiltration. The mRNA expression of CaMKⅡ and CREB and the protein expression of p-CaMKⅡ and p-CREB in both the hippocampal and heart tissue were reduced （P<0.05， P<0.01）. The KN93 + high， medium， and low dose groups of modified Chaihu Shugansan showed further improvements in these abnormalities compared to the KN93 group. ConclusionThe modified Chaihu Shugansan exerts antidepressant and myocardial protective effects in rats with myocardial ischemia and depression， possibly related to bidirectional regulation of the CaMKⅡ/CREB signaling pathway， with the high-dose modified Chaihu Shugansan showing the best effects.

Objective To observe the effects of four different modeling method on the hypothalamus-pituitary-adrenal(HPA)axis,blood rheology,platelet aggregation rate,and myocardial ischemia in rats,and to provide new ideas for the establishment of a rat model of"double heart"disease in line with clinical diagnosis and treatment characteristics.Methods Sixty-nine male Sprague-Dawley rats were divided randomly into a Control group(unstimulated),chronic unpredictable mild stimulation(CUMS)group,isoproterenol(ISO)group(intraperitoneal injection of ISO),high-fat diet(HFD)group(fed high-fat chow),and composite model(CUMS+ISO+HFD)group(n=12 rats in the Control and HFD groups;n=15 rats in the other three groups,respectively).Modeling procedures were carried out for a total of 8 weeks,with ISO injection started from week 6 of the experiment for a total of 3 weeks.At the end of modeling,rats in each group were subjected to absent-field and sugar-water preference behavioral tests.Electrocardiography(ECG)was performed to observe changes in ECG lead Ⅱ in each group.Serum levels of adrenocorticotropic hormone(ACTH),cortisol(Cor),corticosterone(CORT),endothelin-1(ET-1),and soluble intercellular adhesion molecule-1(sICAM-1)were detected by enzyme-linked immunosorbent assay.Myocardial histopathological changes were detected by hematoxylin/eosin(HE)staining.Serum total cholesterol(TC),triglycerides(TG),low-density lipoprotein cholesterol(LDL-C),and high-density lipoprotein cholesterol(HDL-C)were measured using an enzyme labeling instrument.Whole-blood high-cut viscosity(200 V/S),whole-blood low-cut viscosity(10 I/S),plasma viscosity,and fibrinogen were assessed using an automatic blood rheology analyzer.The maximum platelet aggregation rate(MAR)and average platelet aggregation rate(AAR)induced by arachidonic acid and adenosine diphosphate were detected using a whole-blood platelet aggregometer.Results Compared with the Control group,all four model groups had significantly lower absenteeism distance and number of entries into the central region in the absent-field test,and a lower sugar-water preference ratio(P＜0.01).ECG revealed ST-segment elevation in the ISO and CUMS+ISO+HFD groups,tachycardia in the CUMS group,and mild ST-segment elevation in the HFD.Serum ACTH,Cor,CORT,ET-1,and sICAM-1 were all significantly elevated in the four model groups(P＜0.01).HE staining showed that myocardial tissue was severely damaged in rats in the ISO and CUMS+ISO+HFD groups,with pathological changes such as localized fibrosis and inflammatory infiltration of the myocardium,while mild cardiomyocyte disarrangement and fracture was seen in the CUMS and HFD groups.Rats in the HFD group had increased serum TC and LDL(P＜0.01)and decreased HDL contents(P＜0.01).Compared with the Control group,whole-blood high-cut viscosity(200 V/S),whole-blood low-cut viscosity(10 I/S),plasma viscosity,and fibrinogen were all increased in the CUMS,HFD,and CUMS+ISO+HFD groups(P＜0.01,P＜0.05),while whole blood high-cut viscosity(200 V/S),whole blood low-cut viscosity(10 I/S),plasma viscosity,and fibrinogen levels were decreased in rats in the ISO group(P＜0.01,P＜0.05).MAR and AAR were significantly higher in rats in the CUMS,HFD,and CUMS+ISO+HFD groups(P＜0.01),while the platelet aggregation rate was decreased in the ISO group compared with the Control group(P＜0.01,P＜0.05).Conclusions These result showed that the rat CUMS+ISO+HFD model better reflected the complexity of clinical double heart disease than the other three models.

Objective:To study the implementation progress of the prevention and control measures for drinking water-borne endemic fluorosis and the changing trend of fluorosis conditions in Inner Mongolia Autonomous Region, comprehensively evaluate the effectiveness of prevention and control measures, and provide a basis for the next step of prevention and control of the disease.Methods:In 2015 and 2023, a cross-sectional survey method was used to investigate the water improvement situation, the operation of water improvement projects, the detection of fluoride level in water, and the prevalence of dental fluorosis in children aged 8 to 12 in all affected villages of 11 leagues (cities) in the entire autonomous region. The prevention and control effect of drinking water-borne endemic fluorosis in the entire autonomous region was evaluated.Results:The water improvement rates of all affected villages in the entire autonomous region in 2015 and 2023 were 84.12% (8 218/9 769) and 95.38% (8 944/9 377), respectively. The qualified rates of water fluoride in the villages with water improvement in the entire autonomous region were 66.21% (5 441/8 218) and 91.00% (8 139/8 944), respectively. The water improvement rate and water fluoride qualification rate of water improvement villages in 2023 were both higher than those in 2015, and the differences were statistically significant (χ 2 = 652.96, 1 593.81, P < 0.001). The detection rates of dental fluorosis in children aged 8 to 12 years in the entire autonomous region in 2015 and 2023 were 9.26% (7 548/81 484) and 4.46% (3 441/77 155), respectively. The detection rate of dental fluorosis in children in 2023 was lower than that in 2015, and the difference was statistically significant (χ 2 = 1 418.20, P < 0.001). In 2015 and 2023, the total compliance rate of all affected villages in the entire autonomous region reaching the control standards were 57.94% (5 660/ 9 769) and 92.37% (8 662/9 377), respectively. The total compliance rate of all affected villages in 2023 was higher than that in 2015, and the difference was statistically significant (χ 2 = 3 010.38, P < 0.001). Conclusions:Compared with 2015, the prevention and control measures of drinking water-borne endemic fluorosis in Inner Mongolia Autonomous Region have been effectively implemented in 2023, with a significant decrease in the detection rate of dental fluorosis in children. However, there are still a few affected villages that have not achieved the control standards, and prevention and control work still need to be further strengthened.

Objective:To investigate the characteristics of the population of skeletal fluorosis patients in drinking-tea-borne endemic fluorosis (referred to as drinking-tea-borne fluorosis) areas in Inner Mongolia Autonomous Region (referred to as Inner Mongolia) and the influencing factors of treatment willingness, and to provide a basis for improving the prevention and control measures of drinking-tea-borne fluorosis and the treatment plan of skeletal fluorosis.Methods:From August to October 2022, a face-to-face questionnaire survey was conducted in key areas of drinking-tea-borne fluorosis in Inner Mongolia (administrative villages with an average daily intake of tea fluoride > 3.5 mg and skeletal fluorosis patients identified by the general survey of drinking-tea-borne fluorosis in Inner Mongolia in 2019), and to investigate the demographic, severity, and treatment status of patients with skeletal fluorosis, analyze the demographic characteristics of patients with skeletal fluorosis and the influencing factors of treatment willingness.Results:A total of 734 patients with skeletal fluorosis were investigated, including 543 mild cases, 125 moderate cases and 66 severe cases. The gender ratio of patients with skeletal fluorosis was 0.71 ∶ 1.00 (305/429), the age was concentrated in > 50 - 70 years old (70.57%, 518/734), the proportion of Mongolians was 94.28% (692/734), the proportion of herders was 97.68% (717/734), the educational level was mainly primary school (54.63%, 401/734), and the proportion of poor households and immigrants who had moved to their current residence was 7.08% (52/734) and 8.04% (59/734), respectively. The distribution of the severity of skeletal fluorosis in patients of different ages, genders, and educational levels was compared, and the differences were statistically significant ( P < 0.05). Fifty-three point two seven percent (391/734) of the patients had a willingness to undergo non-pharmacological treatment, of which 69.82% (273/391) had already started non-pharmacological treatment, with a treatment effectiveness rate of 73.99% (202/273). Sixty-five point two six percent (479/734) of the patients had a willingness to receive medication treatment, of which 7.31% (35/479) had already started medication treatment, with a treatment effectiveness rate of 54.29% (19/35). Zero point two seven percent (2/734) of the patients expressed a willingness to undergo surgical treatment, while no patients underwent surgical treatment. Multivariate logistic regression analysis showed that the age, ethnicity, occupation, educational level, poverty status, immigrants status, and the severity of skeletal fluorosis were all influencing factors of non-pharmacological treatment willingness ( P < 0.05). Occupation, educational level, poverty status, immigrants status, and the severity of skeletal fluorosis were all influencing factors of medication treatment willingness ( P < 0.05). Conclusions:Patients with skeletal fluorosis caused by tea drinking in Inner Mongolia are mainly from Mongolian ethnic groups, herders, middle-aged and elderly people, and those with a lower educational levels. The willingness of patients to receive treatment is influenced by various factors, and corresponding intervention measures can be formulated and taken based on these influencing factors to effectively improve the disease prevention awareness and treatment willingness of patients and the public.
