Objective To investigate the dietary patterns of rural residents in the high-incidence areas of esophageal cancer (EC), and to explore the clustering and influencing factors of risk factors associated with high-incidence characteristics. Methods A special structured questionnaire was applied to conduct a face-to-face survey on the dietary patterns of rural residents in Yanting county of Sichuan Province from July to August 2021. Univariate and multivariate logistic regression models were used to analyze the influencing factors of risk factor clustering for EC. Results There were 838 valid questionnaires in this study. A total of 90.8% of rural residents used clean water such as tap water. In the past one year, the people who ate fruits and vegetables, soybean products, onions and garlic in high frequency accounted for 69.5%, 32.8% and 74.5%, respectively; the people who ate kimchi, pickled vegetables, sauerkraut, barbecue, hot food and mildew food in low frequency accounted for 59.2%, 79.6%, 68.2%, 90.3%, 80.9% and 90.3%, respectively. The clustering of risk factors for EC was found in 73.3% of residents, and the aggregation of two risk factors was the most common mode (28.2%), among which tumor history and preserved food was the main clustering pattern (4.6%). The logistic regression model revealed that the gender, age, marital status and occupation were independent influencing factors for the risk factors clustering of EC (P<0.05). Conclusion A majority of rural residents in high-incidence areas of EC in Yanting county have good eating habits, but the clustering of some risk factors is still at a high level. Gender, age, marital status, and occupation are influencing factors of the risk factors clustering of EC.

Objective To investigate the expressions of 12 cytokines(IL-1β,IL-2,IL-4,IL-5,IL-6,IL-8,IL-10,IL-12p70,IL-17,IFN-α,IFN-γ,TNF-α)and procalcitonin in patients with infective endocarditis(IE).Methods Ten IE patients admitted to our hospital from December 2021 to December 2022 were included into the IE group,10 patients with non-infectious and non-rheumatic valvular diseases who were admitted to our hospital at the same period were randomly selected as the control group,and blood sampling of all patients were conducted at admission.The expressions of 12 cytokines and blood routine indexes were detected by flow cytometry,and the level of procalcitonin was detected by ELISA.The correlations among the expression levels of cytokines in IE patients were analyzed by Pearson method and the correlations of IL-8 level and white blood cell count with procalcitonin in IE patients were analyzed by Spearman method.Results Compared with the control group,the levels of cytokines of IL-1β,IL-2,IL-6,IL-10,TNF-α,IFN-α,IFN-γ and IL-12p70 in the IE group were significantly increased(P<0.05),the white blood cell count,neutrophil percentage and procalcitonin were significantly increased(P<0.05).There was no significant difference in the percentage of monocytes between the two groups(P>0.05).IFN-α of IE patients was positively correlated with IL-2,TNF-α,IL-1β and IL-12p70,IL-2 was positively correlated with TNF-α and IL-1β,IL-12p70 was positively correlated with IFN-γ,and procalcitonin was significantly positively correlated with IL-8 and white blood cell count,with statistically significant differences(P<0.05).Conclusion The levels of IL-1β,IL-2,IL-6,IL-10,TNF-α,IFN-α,IFN-γ,IL-12p70 and procalcitonin in IE patients are significantly higher than those in the normal population,and the detections of these indicators are of guiding significance for the early diagnosis of IE and the evaluation of the severity of the disease.

Objective:To investigate the effects of different doses of rosuvastatin on blood lipid levels and 1-year outcomes in patients undergoing coronary artery bypass grafting.Methods:A total of 106 patients who underwent coronary artery bypass grafting at the Affiliated Hospital of Jining Medical University from February 2020 to February 2022 were prospectively selected and randomly divided into two groups using a random number table. The high-dose group (53 cases) was treated with 20 mg/d rosuvastatin, while the low-dose group (53 cases) was treated with 10 mg/d rosuvastatin. The two groups were compared after treatment in terms of the clinical efficacy, blood lipid levels [total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C)], cardiac function indicators [left ventricular end diastolic diameter (LVDD), left atrial diameter (LAD), left ventricular ejection fraction (LVEF), one-year follow-up [recurrence, readmission, death, major adverse cardiovascular events (MACE)], and adverse reactions (liver injury, elevated creatine kinase, gastrointestinal reactions, rash).Results:The total effective rate of the high-dose group was 94.34%(50/53) higher than that of the low-dose group, which was 77.36%(41/53) ( P<0.05); After treatment, the levels of TC, TG, and LDL-C in both groups decreased, while the level of HDL-C increased (all P<0.05), and the levels of TC, TG, and LDL-C in the high-dose group were lower than those in the low-dose group, while the level of HDL-C was higher than that in the low-dose group (all P<0.05); After treatment, LVDD and LAD in both groups decreased, while LVEF increased (all P<0.05), and LVDD and LAD in the high-dose group were lower than those in the low-dose group, while LVEF was higher than that in the low-dose group (all P<0.05); After a one-year follow-up, the recurrence rate of the high-dose group was 7.55%(4/53), and the readmission rate was 5.66% (3/53), both lower than those of the low-dose group [26.42%(14/53), 20.75%(11/53)] (all P<0.05). There was no statistically significant difference in case fatality rate, MACE, and incidence of adverse reactions between the two groups (all P>0.05). Conclusions:The use of high-dose rosuvastatin in patients undergoing coronary artery bypass grafting can effectively reduce blood lipid levels, improve cardiac function, and has high safety. It is worthy of clinical application.

Objective:To investigate the effect of autologous hematopoietic stem cell transplantation (auto-HSCT) bridging to chimeric antigen receptor T cell (CAR-T) immunotherapy for follicular lymphoma (FL) transformed to B-lymphoblastic leukemia/lymphoma (B-LBL).Methods:The diagnosis and treatment of 1 patient with FL transformed to B-LBL admitted to the First Hospital of Soochow University in August 2020 were retrospectively analyzed and the literature was reviewed.Results:The male patient was 65 years old, and was diagnosed as FL (stage Ⅳ group A, FL international prognostic index -1 score 3 points, high-risk group) in August 2020. And then he was given 6 courses of RB (rituximab combined with bendamustine) regimen, with complete remission (CR) at mid-term and end-stage PET-CT, followed by regular maintenance therapy with rituximab every 2 months, and disease progressed after 4 courses of maintenance therapy. According to the results of histopathology and bone marrow aspiration in December 2021, he was diagnosed B-LBL involving the bone marrow. Partial remission was achieved after induction therapy with zanubnulindb combined with hyper CVAD (cyclophosphamide + doxorubicin + vindesine + dexamethasone) regimen, followed by auto-HSCT bridging to CAR-T treatment targeting CD19 and CD22, which proceeded smoothly with cytokine release syndrome grade 0, immune effector cell-associated neurotoxicity syndrome grade 0. The patient successfully underwent hematopoietic reconstruction and orally taken ibrutinib after discharge. PET-CT indicated CR 2 months after transplantation and he was still in disease-free survival state.Conclusions:The prognosis of FL transformed to B-LBL is poor, and auto-HSCT bridging to CAR-T can improve the prognosis and prolong the survival time of patients who cannot undergo allogeneic hematopoietic stem cell transplantation.

ObjectiveTo understand the physical development level of 3-7 years old children in Zhag′yab， and to provide reference for local health decision-making. MethodsA cross-sectional study was conducted between June 2021 and July 2021， with a sample of 1 247 Tibetan children aged 3-7 years from kindergartens in 13 districts of Zhag′yab. Their height and weight were measured and the hemoglobin was detected by a unified method. Standard statistical method was adopted （Z-score method）. Z-scores of length /height-for-age （HAZ）， Z-scores of weight-for-age （WAZ）， Z-scores of body mass index （BMI）-for-age （BAZ） and Z-scores of weight-for-height （WHZ） were calculated by WHO Anthro v3.2.2 and WHO Anthro Plus. The nutritional status of children was evaluated according to WHO diagnostic criteria for malnutrition and anemia. ResultsThe average WAZ and HAZ of children aged 3 to 7 in Zhag′yab were lower than the WHO standards，except for the WAZ of 4-year old， the differences were statistically significant （P<0.05）. The overall detection rate of malnutrition was 25.7%， stunting， underweight， wasting， overweight， obesity and anemia were 11.6%， 11.8%， 10.8%， 3.3%， 1.8% and 29.3%， respectively. The detection rates of all indicators in boys were higher than those in girls， and the differences were not statistically significant （P>0.05）. The overweight rate and obesity rate of rural children were lower than those of urban children， and the other detection rates were higher than those of urban children. The differences of underweight rate， obesity rate and anemia rate were statistically significant between urban and rural children （P<0.05）. Among the detection rates of all indicators in different age groups， there were statistically significant differences in the overweight rate and the anemia rate （P<0.05）. The overweight rate of children aged 4 and the anemia rate of children aged 5 were the highest. ConclusionsThe physical development of children aged 3 to 7 in Zhag′yab is poor， and the prevalence of malnutrition and anemia is high. Underweight and anemia are more serious in rural children， and the overweight and obesity problem of urban children is emerging. More attention should be paid to promote their nutritional status. The prevention and intervention of children’s malnutrition should be strengthened in Zhag′yab.

OBJECTIVE: To build bridges between anti-α enolase antibody (anti-enolase 1 antibody, anti-ENO1 antibody) and common clinical and laboratory characteristics of systemic lupus erythematosus (SLE) and to analyze the role of anti-ENO1 antibody in the evaluation of SLE disease activity. METHODS: The SLE patients with retinopathy and without retinopathy were enrolled in the study, as well as healthy individuals whose gender and age matched with those of the SLE patients. Serum anti-ENO1 antibodies were measured using enzyme-linked immunosorbent assay (ELISA), presenting as intra-group positive rate and arbitrary units (AU) value. Clinical and laboratory data were obtained from medical records. RESULTS: The SLE retinopathy patients represented various fundus abnormalities. Ranked by percentage, the top three retinopathies were retinal hemorrhage (14/32, 43.75%), cotton-wool spots (8/32, 25.00%) and retinal vein occlusion (3/32, 9.38%). Among the 32 SLE retinopathy patients, 13 (40.63%) suffered from two or more fundus abnormalities. The positive rate and AU value of the SLE patients were higher than of the SLE patients without retinopathy (68.75% vs. 46.00%, P=0.043; 16.11%±10.35% vs. 12.06%±6.47%, P=0.045). Besides, the positive rate and AU value of the two SLE groups were both significantly higher than those of the healthy control group (P < 0.001). Compared with the SLE-without-retinopathy group, the systemic lupus erythematosus disease activity index (SLEDAI)-2000 of the SLE retinopathy patients were significantly higher than those of the SLE patients without retinopathy (17.41±4.25 vs. 9.48±5.35, P < 0.001). Dividing all the SLE patients into an anti-ENO1-positive group and an anti-ENO1-negative group, we found that anti-ENO1-positive was more likely to be correlated to developing fever and positive result of urine occult blood (P=0.011, P=0.042). Comparing with the patients with negative anti-ENO1 antibodies, the patients with positive anti-ENO1 antibodies had significantly higher erythrocyte sedimentation rate (ESR) [the median (range) was 29.50 (1.52-110.00) mg/L vs. 12.00 (4.00-101.00) mg/L, P=0.001], higher immunoglobulin G (IgG) [the median (range) was 14.30 (4.02-37.80) g/L vs. 10.46 (2.50-25.73) g/L, P=0.000 3], and higher blood platelet count (PLT) [(205.87×10⁹±67.98×10⁹) /L vs. (164.57×10⁹±69.57×10⁹) /L, P=0.008], as well as higher immunoglobulin A (IgA) [the median (range) was 2.85 (0.07-27.00) g/L vs. 2.05 (0.42-4.36) g/L, P=0.014]. CONCLUSION The positive rate and AU value of anti-ENO1 antibody suggested higher SLE disease activity and they were elevated in SLE and SLE retinopathy.

Objective:To investigate the effects of micropulse laser photocoagulation under threshold on serum malondialdehyde(MDA) and chemokine levels in patients with proliferative diabetic retinopathy(PDR).Methods:From October 2014 to February 2016, 102 patients with PDR who were treated in Lishui People's Hospital were selected and divided into two groups by random number table method, with 51 cases in each group.The patients in the control group were treated with traditional grating laser, and the patients in the observation group were treated with micropulse laser photocoagulation under threshold.The levels of MDA and chemokine were compared before and after treatment, and the changes of vision and clinical efficacy were observed.Results:The total effective rate of the observation group was 90.20%(46/51), which was higher than that of the control group [76.47%(39/51)](χ 2=19.585, P<0.01). Before treatment, there were no statistically significant differences in serum MDA, chemokine and visual acuity between the two groups(all P>0.05). After treatment, the serum MDA and chemokines in the observation group were (8.57±2.48)μmol/L and (1.58±0.51)ng/L, respectively, which were lower than those in the control group [(10.92±3.16)μmol/L and (2.83±0.92)ng/L]( t=4.178, 8.486, all P<0.05), which in both two groups after treatment were lower than those before treatment(all P<0.05). The visual acuity of the observation group was (0.66±0.19), which was higher than that of the control group(0.43±0.13)( t=7.135, P<0.05). Conclusion:Micropulse laser photocoagulation under threshold can effectively alleviate oxidative stress and reduce serum MDA and chemokine levels in patients with PDR.

Jieji Nabao is a common Tibetan herb. According to our ethnobotanical studies, one of its original plants is identified as Gentiana crassicaulis Duthie ex Burk. (Gentianaceae). Endemic to the Qinghai-Tibet Plateau, this medicinal alpine plant is a threatened species. In this study, 163 individuals from 20 populations of G. crassicaulis were collected throughout its geographical range and amplified fragment length polymorphism (AFLP) was used to investigate genetic variation in this species. A cluster analysis was performed on the AFLP data with Halenia elliptica and Gentiana straminea as the outgroups. From 64 pairs of AFLP primer combinations, 12 pairs were selected for amplification and a total of 315 bands were amplified, of which 254 bands were polymorphic, accounting for 80.63%. High genetic differentiation was detected between populations (87%), and low within populations (13%). The UPGMA (unweighted pair-group method with arithmetic means) tree was topologically consistent with the traditional taxonomic treatments at the species level, and the populations of G. crassicaulis were divided into two branches: one from Yunnan and Guizhou, the other from Tibet, Qinghai, Sichuan and Gansu. PCA analysis and the Mantel test showed that there was a positive correlation between genetic distance and geographical distance. In addition, combined with SSR and SNP markers within cpDNA, the genetic differentiation within the Sichuan population S1 was validated.
