ABSTRACT
Hyperglycemia is prevalent and closely associated with pulmonary tuberculosis (PTB). This study aimed to investigate the effects of hyperglycemia on the outcomes of PTB treatment. This study comprised 791 patients with PTB in total. Patients with fasting plasma glucose levels of ≥ 6.1 mmol/L were diagnosed with hyperglycemia. Anthropometric and baseline demographic data were also collected. The treatment response was assessed based on clinical symptoms (sputum production, cough, chest pain, fever, hemoptysis, night sweats, loss of appetite, and fatigue), sputum smear, chest computed tomography (CT), and adverse gastrointestinal responses (vomiting, nausea, abdominal distension, diarrhea, and constipation). A generalized estimating equation (GEE) was used to evaluate these relationships. Hyperglycemia affected 266 (33.6%) of the 791 patients with PTB. In GEE analyses, patients with hyperglycemia exhibited a greater incidence of elevated tuberculosis (TB) scores (odds ratio (OR) 1.569; 95% CI 1.040-2.369), cough (OR 1.332; 95% CI 1.050-1.690), and night sweats (OR 1.694; 95% CI 1.288-2.335). Hyperglycemia was linked with a higher risk of positive sputum smears (OR 1.941; 95% CI 1.382-2.727). During therapy, hyperglycemia was also associated with an increased incidence of vomiting (OR 2.738; 95% CI 1.041-7.198), abdominal distension (OR 2.230; 95% CI 1.193-4.171), and constipation (OR 2.372; 95% CI 1.442-3.902). However, the CT results indicated that hyperglycemia did not affect pulmonary lesions in patients with TB. Patients with TB and hyperglycemia are at a higher risk of severe clinical manifestations, positive sputum smears, and adverse gastrointestinal effects and, therefore, the special situation of hyperglycemic patients should be considered in the prevention and treatment of TB.

Object:To explore the clinical effect of periacetabular osteotomy (PAO) in the treatment of developmental dysplasia of hip (DDH).Methods:The clinical data of 305 patients with DDH admitted to Tangshan Second Hospital from January 2012 to June 2018 were analyzed retrospectively. All patients were treated with PAO alone. There were 123 cases of left hip dysplasia, 131 cases of right hip dysplasia and 51 cases of double hip dysplasia (356 hips in total). The patients underwent X-ray examination before and on the second day after operation to compare the acetabular index and the lateral center edge angle (LCEA) and the anterior center edge angle (ACEA) of the acetabulum before and after operation. The ability of daily living and hip joint function were evaluated before and 6 months after operation, and Barthel index and Harris score of hip joint were compared before and after treatment. The measurement data with normal distribution are expressed in xˉ± s, and the paired t test was used for comparison before and after operation. The measurement data of non-normal distribution is expressed by M( Q1, Q3), and the comparison before and after surgery is performed by the rank sum test. Results:On the second day after operation, the LCEA and ACEA of 356 hip joints in 305 patients were greater than those before operation (32.5(20.0,47.5)° vs 8.5(-18.5 23.0)°, 29.0(18.5,52.3)° vs 2.5(-20.8, 24.5)°), while the acetabulum index was lower than that before operation (6.7(-8.4,12.5)° vs 26.8(10.0, 62.3)°), and the differences were statistically significant ( Z values were 51.50, 45.37, 32.22, all P<0.001). After 6 months of follow-up, the Barthel score and Harris score of the hip joint were higher than those before the operation (92.5±1.3) scores vs (65.6±1.5) scores, (96.4±2.5) scores vs (85.1±1.3) scores, and the difference was statistically significant ( t values were 335.56 and 89.70, both P<0.001). Conclusions:PAO can make the acetabulum cover the femoral head well through acetabular transposition, improve the ability of daily living and hip joint function of DDH patients, reduce pain, increase joint range of motion, and correct limb deformities. It is an effective means to treat DDH.
ABSTRACT
Infant nutritional status evaluation is a basic experimental skill in the experimental teaching of nutrition and food hygiene. The construction of this virtual simulation experiment can solve the problems of activeness and poor coordination of infants and young children in the actual operation of the experiment. And based on the application of this virtual simulation project, the experimental teaching method of preventive medicine was explored. This experiment adopted online and offline mixed teaching method, which enriches teaching measures and strengthens the standardized process of infant nutritional status evaluation. After 3 semesters of practice from spring 2018 to spring 2020, the proportion of students who achieved excellent grades was 30.09% (34/113), 56.02% (279/498) and 66.79% (1 080/1 617), respectively, which increased significantly year by year ( Ptrend < 0.001). Among all the 2 228 students, 1 983 students (89%) believed that this experimental teaching could better cultivate the ability of autonomous learning. Through the study of virtual simulation experiments, students have improved their subjective initiative, and laid a foundation for the improvement of students' overall quality and the requirements of school elite education.
ABSTRACT
The registered dietitian system started late in China, and since 2014 a working committee of registered dietitians has been formed by the Chinese Nutrition Society to establish a national accreditation system in accordance with the international standard academic and internship requirements. The data from the certification examinations and registrations were collected and analyzed. 8,328 registered dietitians were included in the study, with 5,673 registered dietitians (RD) and 2,655 registered dietetic technicians (DTR). Among them, 45.27% of RDs have master degree or above, and 66.44% of DTRs have bachelor or above. 53.25% RDs work in medical institutions, 14.77% in colleges and universities, and 14.56% in enterprises; 48.21% DTRs work in the medical institutions, 30.28% in enterprises, and 7.34% in the community. Although six years of work has initially established a foundation of standardized registered dietitian accreditation system, the problems of limited resources for academic education and the lack of legislative protection for the profession remain prominent.

Objective:To analyze the competence assessment examinations of registered dietitians in China during 2017-2021 to inform the training of dietetic professionals.Methods:A systematic review was conducted about the composition and changing trends of examination participants during 2017-2021. Participants were divided into subgroups based on gender, age, education, professional background and affiliations and the qualification rate was compared across different subgroups.Results:The number of examination participants showed an increasing trend overall, with the majority being females and aged 26-35 years. The ratio of participants with bachelor's: master's: doctor's degree was about 15: 9: 1. The proportion of participants majoring in nutrition science decreased from 32.1% to 20.3%, while that of participants majoring in other medical and food sciences increased. Among participants from healthcare institutions, a decreasing proportion of participants were with a major in nutrition science, while this proportion among participants from companies were stable at 38.8% to 50.2%. The average qualification rate was 35.7%, showing no significant differences among different gender and age groups. But the qualification rate varied significantly across subgroups with different education level, professional background, and affiliations ( P < 0.05). Subgroups with more advanced degrees showed higher qualification rate and the best rate was observed in the subgroups with professional background in nutrition science and from nutrition-related institutions. Conclusion:The training of dietetic professionals in China should be improved, lifelong learning should be promoted in nutrition practitioners, and the sustainable development of dietitians should be impelled.

ABSTRACT
Objective: To investigate effects of beta-carotene on instestine mucosa barrier function in rats damaged by X-ray radiation. Methods: 40 female SD rats were randomized into 4 groups as the normal control group (Group C) ,the radiation group (Group R) ,the β-C 5 mg/(kg · d) group (Group T1) and the β-C 10 mg/(kg · d) group (Group T2). After 14 days of continuous administration of peanut oil in groups C and R or beta-carotene (2. 5 mL/kg) in groups T1 and T2,the rats in groups R, T1 and T2 were radiated under a 9 Gy dose of X-ray. And then 3 days later,the rats were killed and the amount of diamine oxidase(DAO) and the level of bacterial endotoxin were detected. The structure and length of the crypt-villus axis (CVA) of jejunum were also observed and analyzed. Results: Obvious slow weight gain was observed in group R. Compared with group C, the CVA of group R was significantly shorter (P0.05). The CVA of group T1 was significantly longer than that of group R, but the intestinal mucosal injury was slighter(P 0. 05). Group T2 gained more than group T1 (P 0. 05). Conclusion: Beta-carotene may decrease the X-ray radiation damage on jejunum and maintain the normal function of gut mucosa barrier in rats.

Method:Three hundred subjects aged from 60 to 75y,128 males and 172 females were randomized into 5 groups:group 1(VE 200mg/d+VC 300 mg/d+?-C 16.7 mg/d) ,group 2(VE 200 mg/d+VC 300 mg/d+?-C 8.4 mg/d) ,group 3(VE 200 mg/d+VC 300 mg/d+?-C 5.6 mg/d) ,group 4(VE 200mg/d+VC 300mg/d) ,group 5(VE 5 mg/d) . The trial lasted 16 weeks. All subjects were asked to record the nutrients intake daily. The investigators followed-up and supervised the subjects irregularly. The samples of blood and urine were collected at the beginning and end of the trial. The proliferation of lymphocytes was detected by MTT and H2O2-induced erythrocyte hemolytic degrees were measured before and after the trial. Thefluidity of erythrocyte membrane was evaluated by fluorescence polarization(?) and microviscosity(?) . O6-MeG was analyzed by high performance capillary zone electrophoresis. Results:The proliferation of lymphocytes was increased and H2O2-induced erythrocyte hemolytic degrees were decreased from group 1 to group 4 at the end of trial with significant difference compared with control group 5. The ? and ? values were lower in 1 to 4 groups at the end of trial. O6-MeG was significantly lower in group 1 to 4 group at the end of trial,and group 1 lower than group 4. Conclusion:Different doses of natural antioxidant ?-carotene supplement combined with vitamin E and C could improve the function of erythrocyte and the proliferation of lymphocytes,and decrease DNA alkylating damage.
ABSTRACT
Aim To investigate whether d-?-tocopherol supplementation had protective effect on the pro-oxidant-antioxidant state following chronic ethanol treatment in mouse liver and its underlying mechanism.Methods Mice were randomly divided into 5 groups:control(NC),ethanol control(EC),d-?-tocopherol 1(TOC 1),d-?-tocopherol 2(TOC 2)and d-?-tocopherol 3(TOC 3)group.After ingesting ethanol(2.4 g ethanol?kg-1 bw),the mice were treated by d-?-tocopherol(25,50,100 mg?kg-1 bw?d-1,respectively),meanwhile,the normal control group and ethanol control group(2.4 g ethanol?kg-1 bw)were set up.The activities of glutathione peroxidase(GSH-Px),superoxide dismutase(SOD),ATPase and glutathione-S transferase(GST)in liver were measured,meanwhile the concentration of malondialdehyde(MDA)was determined when the mice were continuously treated for 60 d.Results There was significant change in all indices between the ethanol control group and normal control group(P
ABSTRACT
Objective:To study the effect of dietary supplementation of folic acid(FA),VC,VB 6 and taurine on teratogenesis of rats induced by cyclophosphamide. Methods:The teratogenesis was induced by cyclophosphamide. Dietary supplementation of FA, VC, VB 6 and taurine was used to depress teratogenesis in pregnant rats. Results:We found that cyclophosphamide administration resulted in decreased weight and length of the fetuses, increased rate of neural tube defects, and retarded ossification. Supplementation of the diet with FA alone or FA+VC+VB 6+taurine resulted in statistically greater fetal weight and length, decreased rate of neural tube defects, and increased ossification grade of supraoccipital bone. Conclusion:The mixture of FA+VC+VB 6+taurine is superior to FA alone in increasing fetal weight and length, reducing the incidence of neural tube defects, and ossification abnormalities of the supraoccipital bone.

ABSTRACT
Objective: The study was to exlpore the nutritional, antioxidative functions and toxicology of ascorbic acid in different levels in vitro. [WT5FZ]Methods: Hela (human transformed epithelial) cells incubated with three levels of ascorbic acid, i.e. 0.1 mmol/L, 0.25 mmol/L and 0.5 mmol/L, were calculated and a single cell gel electrophoresis (SCGE) was used for measuring DNA oxidative damage. [WT5FZ]Results: The results showed that there were no differences in spontaneous DNA damage of Hela cells incubated with three levels of ascorbic acid. However, there was a less DNA oxidative damage induced by H 2O 2 in 0.1 mmol/L and 0.25 mmol/L of ascorbic acid supplemented groups respectively than in control group. In contrast, more serious DNA damage was found in 0.5 mmol/L ascorbic acid supplemented group. [WT5FZ]Conclusion: It is suggested that the higher levels of ascorbic acid might not directly damage DNA; the moderate supplementation of ascorbic acid may increase antioxidative ability of cells; excess ascorbic acid is harmful to DNA and enhances the susceptibility to H 2O 2 potentially.
