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.

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 explore the reproductive health literacy of young female sailors,investigate the influence of long voyage on the health,and propose strategies on health education.Methods A total of 49 young female sailors were enrolled.Their healthy status was evaluated by annual medical records.The questionnaire survey was also conducted to evaluate general status related to reproductive health,knowledge pertaining to reproductive health,and health status after long voyage.Results Some female sailors had symptoms of thyroid diseases,such as hypothyroidism(32.65%),benign thyroid nodules(59.18%),and suspected papillary carcinoma(in one sailor,2.04%).Ultrasonography revealed breast nodules in 5 subjects(10.00%),mammary gland hyperplasia in 46 subjects(93.88%)and reproductive benign diseases in 6 subjects(12.24%).The physical and mental states significantly changed in the late stage of long voyage.The changes in work and living environment were the main factors affecting the emotional and psychological status in the long voyage.The discomfort in menstrual cycle piled up with the above-mentioned changes during a long voyage,and the menstruation significantly affected the duty of 36.73%of female sailors during a long voyage.Female sailors had little knowledge about the prevention and examination of breast cancer and thyroid cancer.Conclusion The living and work environment during a long voyage may affect the health of the thyroid,mammary gland and reproductive system of young female sailors.Active health education via online and offline ways is helpful to improve the health literacy and self-care of female sailors,subsequently enhancing the combat effectiveness.

Objective To explore the causal association between immune cells and allergic rhi-nitis using Mendelian randomization(MR)approach.Methods GWAS data for 731 types of im-mune cells and allergic rhinitis were obtained from genome-wide association study(GWAS)databas-es.A two-sample bidirectional MR analysis was conducted,with the inverse-variance weighted(IVW)method as the primary analytical approach,and the weighted median method,MR-Egger re-gression,simple mode method,and weighted mode method as supplementary approaches.Sensitivity analyses,including heterogeneity tests,pleiotropy tests,and the leave-one-out method,were per-formed.Bonferroni correction was applied to the preliminary results to enhance their reliability and rigor.Results The two-sample forward MR analysis revealed correlations between 67 immune cell phenotypes and allergic rhinitis.After Bonferroni correction,four immune cell phenotypes were finally identified.Among them,the expression of CD3 on CD39-positive activated CD4 regulatory T cells(OR=0.953,95％CI,0.931 to 0.978,P＜0.001,Padj=0.007),the expression of herpesvirus entry mediator(HVEM)on CD45RA-negative CD4+T cells(OR=0.965,95％CI,0.948 to 0.983,P＜0.001,Padj=0.008),and the percentage of human leukocyte antigen class DR(HLA-DR)-high-expressing monocytes among leukocytes(OR=0.929,95％CI,0.885 to 0.974,P=0.002,Padj=0.157)were protective factors for allergic rhinitis.In contrast,the percentage of transitional B cells among B cells(OR=1.094,95％CI,1.032 to 1.161,P=0.003,Padj=0.183)was a risk factor for allergic rhinitis.The reverse MR analysis showed no causal relationship between allergic rhinitis and the four immune cell phenotypes.Conclusion The two-sample forward MR analysis confirms a caus-al link between immune cells and allergic rhinitis.MR analysis has the advantages of reducing con-founding factor interference and avoiding reverse causation,providing a theoretical basis for in-depth research on immune mechanisms,sensitive biomarkers,and drug treatment targets of allergic rhinitis.

Objective:To investigate the distribution of physical and chemical water improvement areas of drinking water-borne endemic fluorosis in Inner Mongolia Autonomous Region, as well as the use of household water purifiers.Methods:From April to October 2021, a survey was conducted in a drinking water-borne endemic fluorosis areas in Inner Mongolia Autonomous Region where physical and chemical water improvement was carried out. The survey included the basic situation of the affected villages (number of permanent households, number of permanent residents, historical water fluoride content) and the use of residential water purifiers. Household peripheral water samples were collected to test the water fluoride content. Water purifier installation rate, normal usage rate, qualified water fluoride rate in normal usage, and the proportion of households covered by filter replacement departments were calculated.Results:In Inner Mongolia Autonomous Region, the physical and chemical water improvement areas of drinking water-borne endemic fluorosis were distributed in 2 735 villages in 11 leagues (cities) throughout the region, with 192 950 permanent households and 540 216 permanent residents. The average historical water fluoride content in all leagues (cities) was 2.18 mg/L, and the current average water fluoride content was 0.40 mg/L. A total of 134 763 water purifiers were installed, with an installation rate of 69.84% (134 763/192 950). A total of 10 773 households were surveyed, with 10 396 households using water purifiers normally and a normal usage rate of 96.50% (10 396/10 773). Among them, 10 158 households had qualified water fluoride of normal usage, with a qualified water fluoride rate of 97.71% (10 158/10 396). Of the 10 396 households using water purifiers normally, 3 974 households (38.23%) had filter cartridges used within one year, and 3 961 households had qualified water fluoride, with a qualified rate of water fluoride of 99.67% (3 961/3 974). Six thousand four hundred and twenty-two households (61.77%) had filter cartridges used for more than one year, with 6 197 households had qualified water fluoride and a qualified rate of water fluoride of 96.50% (6 197/6 422). There was a statistically significant difference in the qualified rate of water fluoride between purifiers with different filter cartridge usage times (χ 2 = 110.73, P < 0.001). Among the 10 773 surveyed households, the filter cartridges replacement department covered 10 470 households, accounting for 97.19% (10 470/10 773). Conclusions:In Inner Mongolia Autonomous Region, the physical and chemical water improvement areas of drinking water-borne endemic fluorosis are widely distributed, and the normal usage rate of household water purifiers is relatively high. The qualified rate of water fluoride in household water purifiers with filter cartridges used for more than one year is low.

In the past decades, significant progress has been achived in cartilage regeneration. The traditional techniques for constructing tissue engineering cartilage scaffold mainly include pore agent method (or template method), phase separation method, gas foaming method, freeze-drying method, electrospinning method, etc. Cartilage is heterogeneous, and it is difficult for traditional scaffolds to simulate the high anisotropy of cartilage. Therefore, functional regeneration of cartilage is challenging. With the progress of three-dimensional(3D) printing technology, it is possible to prepare functional bionic scaffolds with fine structure and gradient changes through co-deposition of biomaterials, cells and active biomolecules, so as to achieve functional cartilage regeneration. This article reviewed 3D printing technology of cartilage tissue engineering, and the application of 3D printing technology in cartilage regeneration at different anatomical positions (articular cartilage, auricle cartilage, nasal cartilage). In addition, the importance of preparing bionic constructs with regional structure gradient and regional composition gradient was discussed. 3D bioprinting technology, 4D printing techniques, smart biomaterials brought hope for the construction of bionic tissues and organs.

Objectives:We aimed to compare the impact of dissection and re-entry(DR)recanalizing pattern with non-DR on the in-hospital results and prognostic outcomes of patients treated successfully by percutaneous coronary intervention(PCI)of chronic total occlusion(CTO)and examine the benefit of DR in CTO PCI. Methods:A total of 815 consecutive patients with CTO meeting the inclusion criteria in the Department of Cardiology of the First Affiliated Hospital of PLA Air Force Military Medical University from January 2018 to December 2020 were enrolled and divided into DR group(n=239)and non-DR group(n=576)according to whether DR recanalizing pattern was used in the procedure.The clinical characteristics,coronary angiographic characteristics,procedure results,and complications were collected,and the prognostic outcomes within one year after the procedure were observed.Propensity score matching by the clinical and coronary angiographic characteristics was performed and results were compared with 208 matched patients in each group.The endpoints were the major adverse cardiovascular events(MACE)consisting of all-cause death and myocardial infarction,clinically driven target vessel revascularization(TVR)one year after the procedure,and in-hospital outcomes. Results:The mean age of all patients was(60.9±10.9)years old,and 87.4%were male.As compared with the non-DR group,the proportion of blunt cap,ambiguous,calcification,angle＞45°,and diseased landing zone,as well as mean J-CTO score was higher in the DR group(all P＜0.05).The mean stent length and median procedure time were longer in the DR group,median guidewires and consumed contrast volume was also higher in the DR group(all P＜0.001).Incidence of in-hospital death,myocardial infarction,perforation,side branch loss,bleeding of BARC 3rd grade and above,and contrast-related impairment of renal function were similar between the two groups(all P＞0.05).However,peripheral vascular complications occurred more frequently in the DR group(P=0.007).One year after the procedure,the incidence of MACE(2.9%vs.2.4%,log-rank P=0.750)and clinically driven TVR(5.8%vs.3.9%,log-rank P=0.365)as well as all-cause death(2.9%vs.1.0%,log-rank P=0.154)and myocardial infarction(0.5%vs.1.9%,log-rank P=0.184)were similar between the two matched groups.Multivariate Cox regression analysis showed no significant association between DR and MACE(HR=1.129,95%CI:0.427-2.979,P=0.807)and TVR(HR=0.606,95%CI:0.213-1.722,P=0.347).LVEF≤40%(HR=2.775,95%CI:1.137-6.774,P=0.025)and elevated residual SYNTAX score(HR=1.089,95%CI:1.032-1.150,P=0.002)were risk factors for MACE,and diseased landing zone(HR=2.144,95%CI:1.019-4.513,P=0.045),rescued ADR(HR=3.479,95%CI:1.109-10.919,P=0.033),and prolonged procedure time(HR=1.007,95%CI:1.002-1.013,P=0.007)were risk factors for TVR. Conclusions:CTO lesion recanalized with PCI utilizing DR operation pattern was associated with more complex characteristics,more devices and time consumed,and longer stent length,while no significant association was observed between DR operation pattern and MACE and TVR one year after the procedure,as well as in-hospital complication..

Objective:To investigate the epidemic status of drinking-tea type endemic fluorosis (fluorosis for short) in Inner Mongolia Autonomous Region (Inner Mongolia for short), and to provide theoretical basis and basic data for formulation and evaluation of prevention and control measures.Methods:From May to October 2022, a cross-sectional survey was conducted in key areas (168 administrative villages in 6 leagues or cities) identified in the 2019 regional census with tea drinking habits, daily per capita intake of tea fluoride > 3.5 mg, and patients with skeletal fluorosis. The drinking condition of brick tea in 10 households of each administrative village was investigated, and the brick tea samples were collected to detect fluoride level. The prevalence of dental fluorosis in children aged 8 - 12 and skeletal fluorosis in adults aged 16 and older was investigated, and urine samples of patients with skeletal fluorosis were collected to detect urinary fluoride levels.Results:Totally 98.40% (1 657/1 684) of the households in the surveyed areas had a habit of drinking brick tea, with an annual per capita consumption of brick tea and a daily per capita intake of tea fluoride of 5.07 kg and 5.38 mg, respectively. The qualified rate of fluoride level in brick tea samples was 55.64% (922/1 657), the average fluoride level of all other brick tea varieties exceeded the national standard limit (300 mg/kg) except for black brick tea (291.08 mg/kg). Totally 2 747 children aged 8 to 12 were examined, with a detection rate of 13.91% (382/2 747) for dental fluorosis. The disease was mainly mild. There was no statistically significant difference in the detection rate of dental fluorosis among different age groups (χ 2 = 5.53, P = 0.238). Totally 71 708 adults aged 16 and older were examined, and the detection rate of skeletal fluorosis was 1.02% (734/71 708). Patients were mainly aged between 50 and 70 years old, and the condition in each age group was mainly mild. Totally 715 urine samples of skeletal fluorosis patients were collected and tested, and 55.24% (395/715) of the urine samples had fluoride levels higher than 1.6 mg/L. Conclusions:In Inner Mongolia, the proportion of high fluoride brick tea in endemic areas of drinking-tea type fluorosis is high. The detection rates of dental fluorosis in children and skeletal fluorosis in adults are relatively high. The prevention and control situation of drinking-tea type fluorosis is still serious.
