Objective:To explore the application of group sandbox game intervention on emotional state and coping style in patients with gastric cancer.Methods:A total of 92 patients with gastric cancer treated with chemotherapy in the First People′s Hospital of Lianyungang from March 2018 to March 2019 were selected by convenient sampling method, they were divided into two groups according to admission time, 46 patients in the control group received conventional care after chemotherapy, and 46 patients in the observation group received group sandplay therapy for three months which was performed after chemotherapy. The Distress Thermometer(DT), Hamilton Depression Scale (HAMD), Hamilton Anxiety Scale (HAMA), Medical Copingmodes Questionnaire (MCMQ) were used to assess the emotional status and coping style of the patients before and after intervention.Results:After intervention, the DT, HAMA and HAMD scores of the observation group were 2.26±2.09, 13.52±2.50 and 16.47±3.61 respectively, and the DT, HAMA and HAMD scores of the control group were 3.36±2.23 and 20.85±4.53, 23.63±4.82, respectively. The DT, HAMA, HAMD scores in observation group were significantly lower than those in the control group, the difference between the two groups was statistically significant ( t value was 2.441, 9.608, 8.064, P<0.05). The dimensional score of the MCMQ measurement surface of the observation group after intervention was 18.35±3.19, and 14.25±3.04 in the control group. MCMQ scale escape and yield dimension scores in the observation group were 15.26±3.14, 10.24±2.56, and 17.81±2.59 and 12.84±2.64 in the control group. After the intervention, the observation group′s MCMQ surface score was higher than the control group, and the escape and yield dimension score was lower than that of the control group ( t value was 6.311, 4.249, 4.795, P<0.05). Conclusions:Group sandplay therapy can relieve negative emotion in patients with gastric cancer undergoing chemotherapy, and improve their coping style.

Objective To observe PDX-1 expression in the pancreas of type 2 diabetic rat model and effects of rosiglitazone (RGZ) on it. Methods Type 2 diabetic rat model was induced by long-term feeding with high-fat foods followed by a single intraperitoneal injection of low dose of streptozotocin (STZ). The morphological changes of pancreas were examined by microscopy and immunohistochemistry. The mRNA levels of PDX-1 and insulin were determined by RT-PCR. PDX-1 protein expression was detected with Western blot. Results The percentage of insulin-positive cells(12.75±2.18)，the average optical densities of PDX-1-positive area(0.240±0.051)，PDX-1 mRNA level (0.153±0.071)and PDX-1 protein level(0.253±0.028) were significantly lower in untreated diabetic rats than in the controls(42.61±2.68，0.648±0.087，0.49±0.032，0.720±0.036 respectively)(all P＜0.01)，and in RGZ-treated versus untreated group those parameters increased significantly (all P＜0.05~0.01). Conclusions Rosiglitazone could protect islet cell function，and improve PDX-1 expressions in both mRNA and protein levels.

Objective To analyze the contribution of dietary supplements to current vitamin mineral intakes in Beijing,China.Method By stratified cluster sampling method,3992 subjects aged 18y and above in 1440 households were investigated in 6 different regions in Beijing.Results The dietary intake of vitamin and mineral of men was higher than that of women,but the total intake of niacin and vitamin C was lower.Both dietary and total intake of vitamin and mineral in supplement users were higher that those in nonusers.In the group of supplement users,the contribution of supplement to thiamin,riboflavin and calcium intakes was 60% and 70%,47% and 45%,42% and 45% in men and women respectively.The percentage of supplement users who reached the current recommended intakes of vitamins and minerals was higher compared with that of nonusers,about 20 -30 percent higher for vitamin C and calcium.Conclusion The average intakes of vitamin and mineral are improved by using dietary supplements.Dietary supplements should be included in the future nutrition survey in China for improving the accuracy of nutrient’s intake.

Objective: To investigate the average dietary nutrients intake status among Chinese residents between 2010-2012, and to compare the difference between rural and urban areas. Methods: Data were collected from Chinese Nutrition and Health Surveillance between 2010-2012. Based on regional features and economic development levels, China's county-level divisions were classified into four types: big city, medium and small city, ordinary rural area and poor rural area. A total of 62 857 valid subjects, including 14 017, 16 539, 19 910 and 12 391 respondents in each group separately, were enrolled by Multi-stage stratified proportion to the population cluster random sampling method. The dietary survey was conducted by recalling the 24 h diet in 3 consecutive days and weighting condiment. The daily dietary intake of energy, macronutrient, dietary fiber, vitamin, and mineral substance per resident were calculated based on China Food Composition. Results: The average energy intake per resident in Mainland China was 9 047.1 kJ, with highest (9 719.3 kJ) in poor rural area and lowest (8 490.4 kJ) in medium and small city. The average dietary protein intake was 64.2 g, with highest (73.9 g) in big city and lowest (60.7 g) in poor rural area. The average dietary fat intake was 79.7 g, with highest (89.4 g) in big city and lowest (70.6 g) in poor rural area. The average intake of micronutrients of vitamin A, vitamin B₂, vitamin C, calcium, iron, phosphorus, zinc was separately 441.9 μg, 0.8 mg, 80.1 mg, 364.3 mg, and 21.4 mg; which were lower than Chinese Dietary Reference Intakes. The percentage of population whose average intake of vitamin A, vitamin B₂, vitamin C, calcium were lower than estimated average requirement was separately 77.0%, 90.2%, 67.7%, and 96.6%. Conclusion The supply of 3 macronutrient was sufficient in mainland China. However, it was a common issue that there was excessive intake of fat but deficient intake of micronutrients such as vitamin, calcium, iron and zinc. There were differences in nutrition intake among big city, medium and small city, ordinary rural area and poor rural area.

Dehydration is one of the key steps in the biosynthesis of mycolic acids and is vital to the growth of Mycobacterium tuberculosis (Mtb). Consequently, stalling dehydration cures tuberculosis (TB). Clinically used anti-TB drugs like thiacetazone (TAC) and isoxyl (ISO) as well as flavonoids inhibit the enzyme activity of the β-hydroxyacyl-ACP dehydratase HadAB complex. How this inhibition is exerted, has remained an enigma for years. Here, we describe the first crystal structures of the MtbHadAB complex bound with flavonoid inhibitor butein, 2',4,4'-trihydroxychalcone or fisetin. Despite sharing no sequence identity from Blast, HadA and HadB adopt a very similar hotdog fold. HadA forms a tight dimer with HadB in which the proteins are sitting side-by-side, but are oriented anti-parallel. While HadB contributes the catalytically critical His-Asp dyad, HadA binds the fatty acid substrate in a long channel. The atypical double hotdog fold with a single active site formed by MtbHadAB gives rise to a long, narrow cavity that vertically traverses the fatty acid binding channel. At the base of this cavity lies Cys61, which upon mutation to Ser confers drug-resistance in TB patients. We show that inhibitors bind in this cavity and protrude into the substrate binding channel. Thus, inhibitors of MtbHadAB exert their effect by occluding substrate from the active site. The unveiling of this mechanism of inhibition paves the way for accelerating development of next generation of anti-TB drugs.

OBJECTIVETo analyze the mean population intake of salt in Chinese adults in 2010-2012.

METHODSData were from the Chinese Nutrition and Health Surveillance in 2010-2012. The samples were selected through the method of probability proportion to size (PPS). The study objects were 55 531 adults aged 18 and over from 150 sites in 31 provinces, autonomous regions or municipalities in China. The information of oil, salt and other condiments for household was from the 3 d food weighed record. The average of salt intake for individuals was calculated based on the energy percentage in one family. The results presented the level of salt intake (x ± Sx) by analyzing the different demography characteristics. The results were calculated using complex weighting by the population data from National Bureau of Statistics in 2009.

RESULTSThe intake of salt was (9.6 ± 0.3) g/d and it was higher in men ((10.4 ± 0.4) g/d) than that in women ((8.8 ± 0.3) g/d). The intake in the age group of 40-49, 50-59 and 60-69 was (9.9 ± 0.5) g/d, (10.3 ± 0.4) g/d and (9.9 ± 0.3) g/d, respectively. The adults in rural ((10.2 ± 0.3) g/d) had a higher salt intake than that of urban ((9.0 ± 0.5) g/d). An average of salt intake was increased gradually in big city ((7.9 ± 0.3) g/d), medium /small city ((9.2 ± 0.6) g/d) , general rural ((9.9 ± 0.4) g/d) and poor rural ((10.8 ± 0.7)g/d).

CONCLUSIONThe mean salt intake among Chinese adults was still in a very high level. Something should be done to reduce the salt intake for the government and policy-makers.
