ObjectiveTo compare the protective effects of water extracts from fresh and dried Dendrobium huoshanense on gastric mucosa in chronic atrophic gastritis （CAG）. MethodsMale SD rats （n=72） were randomly divided into 9 groups， with 8 rats in each group， which were normal group， model group， Yangwei Shu （4 g·kg^-1） group， low-， medium-， and high-dose fresh D. huoshanense （3.5， 7， and 14 g·kg^-1） groups， and low-， medium-， and high-dose dried D. huoshanense （0.7， 1.4， 2.8 g·kg^-1） groups. The CAG rat model was successfully established by inducing with N-methyl-N'-nitro-N-nitrosoguanidine （MNNG） and other factors for a total of 11 weeks. Then， the rats were intervened with fresh and dried D. huoshanense for 4 weeks. The serum and gastric tissues of the rats were collected. The changes in gastric juice secretion volume and gastric acid pH value in each group were observed. The gastric mucosal injury was observed by naked eyes and hematoxylin-eosin（HE） staining. The gastric mucus secretion level was determined by Alcian blue and periodic acid-Schiff staining（AB-PAS） staining. The expression levels of tight junction proteins Occludin and ZO-1 in gastric tissues were determined by immunofluorescence. The expression levels of serum pepsinogen Ⅰ （PG Ⅰ）， pepsinogen Ⅱ （PG Ⅱ）， gastrin 17 （G-17）， interleukin-1β （IL-1β）， interleukin-6 （IL-6）， and tumor necrosis factor-α （TNF-α） were determined by enzyme-linked immunosorbent assay （ELISA）. The expression levels of aquaporin 1 （AQP1）， aquaporin 3 （AQP3）， and aquaporin 4 （AQP4） in gastric tissues were determined by Western blot. ResultsCompared with the normal group， the model group showed an obviously reduced gastric juice secretion volume （P0.05）， significantly increased gastric acid pH value （P0.01）， gastric mucosa with obvious atrophy， and a significantly reduced gastric mucus secretion volume （P0.01）. The expression of Occludin and ZO-1 in the gastric mucosal barrier was significantly decreased （P0.01）. The levels of PG Ⅰ and PG Ⅱ in the serum were obviously decreased （P0.05， P0.01）， and the levels of G-17， IL-1β， IL-6， and TNF-α were significantly increased （P0.01）. The expression level of AQP1 in the gastric tissue was significantly upregulated （P0.01）， and the expression levels of AQP3 and AQP4 were significantly downregulated （P0.01）. Compared with the model group， each drug administration group could improve the gastric mucosal atrophy of CAG model rats to varying degrees， obviously increase the gastric juice secretion volume of the model rats （P0.05， P0.01）， significantly decrease the gastric acid pH value （P0.01）， obviously increase the gastric mucus secretion volume （P0.05， P0.01）， obviously decrease the expression levels of G-17， IL-6， IL-1β， and TNF-α （P0.05， P0.01）， obviously increase the expression levels of Occludin， ZO-1， PG Ⅰ， and PG Ⅱ （P0.05， P0.01）， obviously upregulate the expression levels of AQP3 and AQP4 （P0.05， P0.01）， and obviously downregulate the expression level of AQP1 （P0.05， P0.01）. ConclusionThe water extracts of fresh and dried D. huoshanense can exert therapeutic effects on CAG by improving gastric mucosal injury， reducing inflammation， and regulating water metabolism. Moreover， the dried D. huoshanense has a better effect.

Objective: To understand the level of nutritional literacy and its influencing factors among schoolage children in grades 4-9 in Guizhou Province, and to explore the relationship between nutritional literacy and physical health, so as to provide reference for improving nutritional literacy and physical health of schoolage children. Methods: Using multistage stratified cluster sampling method, 1 155 schoolage children in grades 4-6 in elementary school and grades 7-9 in secondary schools in three prefectural and municipal cities of Guizhou Province (Zunyi, Tongren, and Bijie) were sampled from February to July 2023, and were surveyed for nutritional literacy by using the "Food and Nutritional Literacy Questionnaire for Chinese Schoolage Children", and their physical health data (data on body measurement indicators, such as height, weight, lung capacity, and vertical jump) were obtained from the physical health surveillance platform. Pearson correlation analysis and binary Logistic regression modeling were used to explore the association between nutritional literacy and physical health. Results: The nutritional literacy score of the study population was (63.50±8.63), and the scores of each level of nutritional literacy in descending order were interactivity (66.09±13.99), functionality (63.84±8.80), and criticism (61.15±14.65); and the scores of cognitive domain of nutritional literacy, and skill domain were (64.71±10.77) (62.97±9.21); food selection, food preparation, and food intake dimension scores were (64.68±13.52) (56.39±12.17) (63.63±10.04), respectively. Differences in the total nutritional literacy scores of schoolaged children who were only children or not, by gender, ethnicity, grade level, primary caregiver, primary caregivers education, and family economic situation were statistically significant (t/F=2.88, -3.28, 5.02, 18.32, 4.67, 32.47, 32.53, P<0.05); the physical health pass rate was 85.8%, and the mean scores of the total physical health score, physical form, physical function, and physical fitness dimensions were (71.86±10.52) (93.29±12.06) (72.12±14.42) (67.26±13.13), respectively; after controlling for confounders, the nutritional literacy scores were positively correlated with physical health (OR=1.03, 95%CI=1.01-1.05, P<0.05). Conclusion Nutritional literacy scores of schoolage children in grades 4-9 in Guizhou Province are low, and there is a positive correlation between nutritional literacy and physical health in this school age children.

Objective:To investigate the dose-response relationship between physical activity and sarcopenia in middle-aged and elderly people in Urumqi, and then provide the reference to guide the middle-aged and elderly people to arrange exercise reasonably.Methods:A total of 1886 middle-aged and elderly people (aged ≥ 50 years old) from December 2018 to December 2019 in Cihui Health Management Center in Urumqi were selected as the research objects to conduct a questionnaire survey, collected general information and physical examination data, and used the International Physical activity questionnaire to investigate and evaluate their daily activities. Diagnostic criteria of the Asian Working Group on Sarcopenia (AWGS) 2019 were used. Logistic regression model was used to analyze the relationship between physical activity and sarcopenia, and restricted cubic spline was used to analyze the dose-response relationship between physical activity and sarcopenia.Results:Among the investigated subjects, 208 people suffered from sarcopenia, and the prevalence rate was 11%. Multivariate analysis showed that after adjusting for confounding factors such as demographic characteristics, moderate and high intensity physical activity was associated with a lower risk of sarcopenia compared with low intensity physical activity ( OR = 0.389, 95% CI 0.261-0.580; OR = 0.055, 95% CI 0.025-0.122). The dose-response relationship between physical activity and sarcopenia showed an approximate 1-shaped dose-response relationship between total physical activity and sarcopenia ( P<0.01). Conclusions:The strength of the association between physical activity and sarcopenia was approximately an "L" shaped curve, and increased physical activity was associated with a lower risk of sarcopenia when physical activity was between 2500 and 3500 MEt-min/week.

Objective:To explore the factors affecting the safety of home environment for device-aided elderly people, so as to provide a basis for improving the safety of the elderly's home environment and promoting aging-adapted reform.Methods:From August 2021 to March 2022, stratified cluster sampling was used to select 326 device-aided elderly people from 8 communities in Urumqi City as the research subject. The survey was conducted using the General Information Questionnaire, Capacity Assessment Standard Table for the Elderly, Home Environment Safety Assessment Scale for the Elderly, and Home Environment Ageing-adapted Reform Cognition and Needs Concise Questionnaire for the Elderly. Multiple linear regression was used to explore the influencing factors of home environment safety for device-aided elderly people.Results:A total of 326 questionnaires were distributed, and 305 valid questionnaires were collected, with an effective recovery rate of 93.56% (305/326) . The influencing factors of home environment safety for device-aided elderly people included housing area, self-evaluation of the home environment, chronic diseases, monthly pension income, and cognition of aging-adapted reform ( P<0.05) . Conclusions:The aging-adapted reform of home environment should focus on elderly people who suffer from chronic diseases, have poor self-evaluation of the environment, have low monthly pension income and cognition of aging-adapted reform. Relevant departments should promote the self-evaluation methods of home environment and knowledge on home aging-adapted reform.

Objective:To evaluate the effect of edaravone on long-term cognitive function in elderly patients undergoing hip replacement.Methods:A total of 160 patients, aged≥65 yr, undergoing elective hip replacement, were divided into 2 groups ( n=80 each) using the random sequence generated by the McLeod-modified Wichmann-Hill pseudo-random number generator: edaravone group (group E) and control group (group C). Spinal-epidural anesthesia was applied in two groups.Edaravone 60 mg (in 100 ml of normal saline, infusion rate 200 ml/h) was intravenously infused from the time point immediately after achieving the anesthesia plane until the following 30 min.Serum chemokine ligand 13 (CXCL13) and interleukin-6 (IL-6) concentrations were detected by enzyme-linked immunosorbent assay before anesthesia, during surgery (30 min after skin incision), and at postoperative days 1, 3 and 7.The Confusion Assessment Method Scale in Chinese was used to detect the postoperative delirium at postoperative days 1, 2, 3 and 7, and the Telephone Interview for Cognitive Status-Modified and ADL score were adopted to assess the cognitive function and quality of daily living, respectively, and the occurrence of cognitive impairment was recorded at 1 and 12 months after surgery. Results:Compared with group C, the total Telephone Interview for Cognitive Status-Modified score and ADL score were significantly increased, the incidence of postoperative delirium and cognitive impairment was decreased, and the serum CXCL13 and IL-6 concentrations were decreased during surgery and at each time point after surgery in group E ( P<0.05). Conclusion:Edaravone can reduce inflammatory responses and improve long-term cognitive function in elderly patients undergoing hip replacement.

China still has more than 30,000 patients of advanced schistosomiasis while new cases being reported consistently. D-dimer is a fibrin degradation product. As ascites being the dominating symptom in advanced schistosomiasis, the present study aimed to explore a prediction model of ascites with D-dimer and other clinical easy-achievable indicators. A case-control study nested in a prospective cohort was conducted in schistosomiasis-endemic area of southern China. A total of 291 patients of advanced schistosomiasis were first investigated in 2013 and further followed in 2014. Information on clinical history, physical examination, and abdominal ultrasonography, including the symptom of ascites was repeatedly collected. Result showed 44 patients having ascites. Most of the patients' ascites were confined in the kidney area with median area of 20 mm². The level of plasma D-dimer and pertinent liver function indicators were measured at the initial investigation in 2013. Compared with those without ascites, cases with ascites had significantly higher levels of D-dimer (0.71±2.44 μg/L vs 0.48±2.12 μg/L, P=0.005), as well ALB (44.5 vs 46.2, g/L) and Type IV collagen (50.04 vs 44.50 μg/L). Receiver operating characteristic curve analyses indicated a moderate predictive value of D-dimer by its own area under curve (AUC) of 0.64 (95% CI: 0.54–0.73) and the cutoff value as 0.81 μg/L. Dichotomized by the cutoff level, D-dimer along with other categorical variables generated a prediction model with AUC of 0.76 (95% CI: 0.68–0.89). Risks of patients with specific characteristics in the prediction model were summarized. Our study suggests that the plasma D-dimer level is a reliable predictor for incident ascites in advanced schistosomiasis japonica patients.

Objective To explore the relationship between sense of coherence and coping styles among patients at the stabile phase after peritoneal dialysis. Methods About 86 patients at stable phase after peritoneal dialysis were recruited in the investigation. The sense of coherence (SOC-13) and medical coping modes questionnaire (MCMQ) were used to evaluate the sense of coherence and coping styles. Results The average score of sense of coherence was (60.93±13.77), which was at a lower level. The scores of coping styles were confrontation, avoidance and resignation, ranked from high to low. Avoidance and resignation dimensions were higher than the norm in coping styles (all P<0.001) and there was no statistically significant difference between confrontation dimension and the norm (P>0.05). There was positive relationship between confrontation and the average score of sense of coherence, comprehensibility, manageability, meaningfulness (all P<0.05). There was negative relationship between resignation and the average score of sense of coherence, comprehensibility, manageability, meaningfulness (all P<0.001). Conclusions Patients at the stable phase after peritoneal dialysis have a lower sense of coherence and are inclined to confrontation and avoidance coping styles. The higher sense of coherence, the more positive coping styles PD patients use. Medical workers should provide personal interventions according to the results of the sense of coherence so that the patients take positive coping styles.

Objective To investigate the clinical features,the radiological characteristics,and the pathological changes of cerebral sparganosis.Methods We retrospectively collectted and summarized the clinical data of 42 patients with cerebral sparganosis from the Iinstitute of Anti-parasitic Diseases of Jiangxi Province and the First Affiliated Hospital of Nanchang University during January 2000 to January 2014.The follow-up period of the 42 patients ranged from 4 to 96 months.Results Forty-two cases (30 males and 12 females) with cerebral sparganosis were enrolled in the study.Among the 42 patients,34 cases suffered from seizures,16 cases experienced headaches,and 14 cases had limb weakness.The brain CT scan showed the small and punctuate calcifications scattering around the lesions in 18 cases.The features of enhanced MRI included aggregating ring-like enhancement in 38 cases,tunnel lesions in 14 cases,and lesion migration in 13 cases.Twenty-four of the 42 patients were performed surgery.The brain tissues revealed multiple inflammatory tunnels,in which live or degenerated larvae were identified in 20 cases,but only eosinophilia tunnels were observed in the other 4 cases.The serum and cerebro-spiral fluid specimens from 18 patients without surgery were positive to spirometra mansoni antigen.Their cerebral lesions disappeared and got a favorable prognosis after administration of praziquantel in long term follow-ups.Conclusions There is a high incidence of cerebral sparganosis in Poyang lake basin.The clinical features of cerebral sparganosis mainly include seizure,headache and hemiparesis.The enhanced lesions show knot or tunnel signs on multi-planar MRI which are associated with the multiple inflammatory tunnels of larvae migration.A longterm administration of high dose opraziquantel can also get a good treatment prognosis without the classical surgical therapy for cerebral sparganosis.

Objective To explore the influence of early rapidly increased amino acid dosaging on the nitrogen balance and growth in preterm infants.Methods A total of 37 prematures admitted to our NICU within 24 hours after birth and with birth weight of 1 000 g to 1 800 g from November 2011 to January 2013 were randomly divided into study group (n =18) and control group (n =19).Parenteral nutrition (PE) was provided in both groups within 24 hours after birth.The starting amino acid dose was 1.5g/kg per day,then rose by 1 g/kg per day in study group and by 0.5 g/kg per day in control group,until to maximum of 3.5 g/kg per day.The dosage of lipids,glucose,and electrolytes in parenteral nutrition was provided routinely.The trial was double-blinded.Results In the first 5 days of PE,the nitrogen balance had no significant difference between these two groups (F =0.025,P =0.652) ; however,the time of regaining birth weight was significantly shorter in study group [(7.23±2.48) d] than in control group [(9.42±2.03) d] (t=-2.090,P=0.044).There were no differences between these two groups in trems of completely feeding time,weight gain rate,head circumference growth rate,length of hospital stay,and hospital costs (all P ＞ 0.05).Meanwhile,the rates of neonatal necrotizing enterocolitis,sepsis,mechanical ventilation administration,and damage of hepatic and renal function were also not significantly different.The administration of different dosages of amino acids did not affect the energy intake in both groups (F =1.893,P =0.218).Conclusions Prematures need early amino acid administration,with a starting dosage of more than 1.5 g/(kg · d).Rapid increase of amino acid dosing will not affect early nitrogen balance in premature infants; meanwhile,it contributes to weight gain without increasing the complications and hospitalization costs.
