Objective　To evalute long-term effect of combined therapy (radical or palliative resection of carcer and intraperitoneal hyperthermic perfusion (IPHP) chemotherapy) for advenced garstric cancer (GC) from October 1987 to October 1997 in our haspital. The cases were randomly divided into two groups: IPHP group (37 cases) and control group (34 cases). In IPHP group, before suture the abdomine, heated 5-Fu solution in abdominal cavity should be maintained at 42～43℃ for 60 minutes. Results　After IPHP chemotherapy, 12 patients with cancer cells widespreading in abdominal carity, refractable ascites were disappeared. All the patients were dischargd after IPHP. The 5-year survival rate in IPHP group (51.6%) was significanfly highter than that in control group (32.3%) (P<0.05).

In order to explore the possibility of Jerusalem artichoke stalk for bioenergy conversion, we analyzed the main composition of whole stalk, pitch, and core of the stalk. Meanwhile, these parts were pretreated with different NaOH concentrations at 121 degrees C. Afterwards, enzymatic hydrolysis was performed to evaluate the pretreatment efficiency. Jerusalem artichoke stalk was characterized by relatively high lignin content (32.0%) compared with traditional crop stalks. The total carbohydrate content was close to that of crop stalks, but with higher cellulose content (40.5%) and lower hemicellulose (19.6%) than those of traditional crop stalks. After pretreatment, the lignin content in the whole stalk, pitch, and core decreased by 13.1%-13.4%, 8.3%-13.5%, and 19.9%-27.2%, respectively, compared with the unpretreated substrates. The hemicellulose content in the whole stalk, pitch, and core decreased 87.8%-96.9%, 87.6%-95.0%, and 74.0%-90.2%, respectively. Correspondingly, the cellulose content in the pretreated whole stalk, pitch, and core increased by 56.5%-60.2%, 52.2%-55.4%, and 62.7%-73.2%, respectively. Moreover, increase of NaOH concentration for pretreatment could improve the enzymatic hydrolysis of the whole stalk and pitch by 2.3-2.6 folds and 10.3-18.5 folds, respectively. The hydrolysis of pretreated stalk core decreased significantly as 2.0 mol/L NaOH was employed, although the increased NaOH concentration can also improve its hydrolysis performance. Based on these results, hot-NaOH can be regarded as an option for Jerusalem artichoke stalk pretreatment. Increasing NaOH concentration was beneficial to hemicellulose and lignin removal, and consequently improved sugar conversion. However, the potential decrease of sugar conversion of the pretreated core by higher NaOH concentration suggested further optimization on the pretreatment conditions should be performed.

Objective To verify the targeting regulatory relationship between microRNA -939 (miR -939) and CD2 -associated protein (CD2AP).Methods The online RegRNA software was used to predict the human CD2AP promoter for potential binding sites complementary to miR -939.HEK -293T cells were cotransfected with hu-man CD2AP promoter plasmid pGL3 -2K and microRNA negative control (miR -NC)or miR -939 mimics,and the relative luciferase activity(RLA)was detected at 24 h post -transfection.HEK -293T cells were transfected with miR -NC or miR -939 mimics for 48 h,and the CD2AP mRNA expression level was detected by adopting reverse tran-script and real -time fluorescence quantification -PCR,while the CD2AP protein expression level was detected by using Western blot.Results (1 )There were 2 miR -939 binding sites at CD2AP promoter region,located at -468 to -491 and -654 to -677 upstream of initiation codon ATG (marked as +1 )relatively.(2)At 30 nmol/L,50 nmol/L,the RLA in miR -NC group and miR -939 group were 6.81 ±0.88 vs 6.07 ±2.24,5.88 ±1 .44 vs 3.94 ± 0.79 relatively,and there were no significant differences between the 2 groups (t =3.04,2.06,all P >0.05),while the RLA between the 2 groups were 5.58 ±0.58 vs 3.29 ±0.64 at 1 00 nmol/L,and the difference was significant between the 2 groups(t =4.07,P <0.05).(3)At 30 nmol/L,50 nmol/L and 100 nmol/L,the relative CD2AP mRNA expression in miR -NC group and miR -939 group were 1 .00 ±0.01 vs 0.80 ±0.08,1 .00 ±0.00 vs 0.80 ±0.1 3 and 1 .00 ± 0.00 vs 0.72 ±0.07 relatively,while the CD2AP mRNA expression was decreased by 20% -30% at each concentration level,and there were significant differences between the 2 groups (t =4.44,2.93,6.84,all P <0.05).(4)At 50 nmol/L, the relative CD2AP protein expression in miR -NC group and miR -939 group were 0.48 ±0.09 vs 0.19 ±0.12,and the CD2AP protein expression was decreased,and the difference was significant (t =3.36,P <0.05).Conclusions CD2AP is the target gene of miR -939,and miR -939 can down -regulate the expression of CD2AP both in mRNA and protein levels by targeting its promoter region,which indicates that miR -939 may mediate the podocyte injury.

Objective: To explore the effectiveness of healthy school canteen intervention on nutritional literacy, food consumption, as well as attitude towards school canteen. Methods: A primary school in Taizhou City was selected as the intervention school, and another comparable primary school was selected as the control one. A total of 320 students (163 in the intervention group and 157 in the control group) received a comprehensive intervention based on the construction of a healthy school canteen in the school,incluling healthy dining environment,food impravement,chef training,nutrition and health education, while the control group did not receive any intervention. Questionnaires survey was administered to both groups before and after the intervention. Results: Before the intervention, no significant differences were found in the total scores of skills and nutrition literacy, frequency of food intake, behaviors and attitudes related to canteen construction between the two groups( P >0.05). Daily intake of vegetables, dairy products, fish/poultry/eggs/lean meat increased by 19.63, 15.95 and 19.63 percentage point respectively ( χ 2=15.25，9.14，13.93， P <0.01). The proportion of students reporting have read related intervention materials in the intervention group(95.71%) was higher than the control group(84.71%) ( χ 2= 11.04, P < 0.01 ). The students in favor of low salt, low oil and low sugar dishes in the intervention group (74.85%) was higher than in the control group(48.41%) ( χ 2=23.73, P <0.01). Conclusion Based on the comprehensive intervention of nutrition and health canteens can improve students nutrition literacy and dietary structure. It is recommended to adopt the form of "home school linkage" to carry out the construction of large sample, multi regional and long term nutrition and health canteens.

Cardiovascular diseases are the most important diseases that endanger national health, and its development process is complex and diverse. Various cardiovascular diseases caused by obesity, such as hyperlipidemia, hyperglycemia and atherosclerosis, are interrelated and interacted each other. Diet, as the main means of prevention and treatment, plays an important role in the occurrence and development of cardiovascular disease. Mori Fructus is one of the first ingredients that are listed in medicinal and edible food. With a wide range of applications in daily life, it contains polysaccharides(polysaccharide, APS), anthocyanins(anthocyanin, LCRA), flavonoids and other bioactive ingredients. With a wide range of antioxidant, anti-aging, hypoglycemic and hypolipidemic activities, these materials exert effects in alleviating diabetes, hyperglycemia, hyperlipidemia and other cardiovascular diseases. In this paper, we retrieved such databases as PubMed, Web of science, CNKI, VTTMS, Wan Fang, and collected literatures about the effect of single administration of mulberry on cardiovascular diseases in the past 15 years, with "mulberry and cardiovascular disease" as the key word, and summarized the latest progress. The results of many experimental studies have showed that different forms of mulberry can significantly alleviate obesity, diabetes, atherosclerosis, hyperlipidemia and hypertension, suggesting that the scope of action of Mori Fructus covers different pathological stages of cardiovascular diseases. This paper systematically analyzes and summarizes the application forms, efficacy and the existing problems of these experiments, and provides study thinking and development direction for the utilization and new product design of Mori Fructus-related products in the treatment of cardiovascular diseases.

Background Excessive intake of sugar-sweetened beverages (SSBs) is harmful to health. In recent decades, the consumption of SSBs by Chinese residents has increased rapidly, increasing the risk of death and burden of disease. Objective To analyze the knowledge level and influencing factors of SSBs for Chinese residents aged 18-64 years in 2021. Methods A multi-stage cluster random sampling approach was used to conduct a questionnaire survey among residents aged 18-64 years in 302 survey sites across the country in 2021, and 98567 valid questionnaires were obtained. Four questions are about SSBs among the questionnaire's 5 dimensions. Respondents who answered 3 or more questions correctly were considered to have a basic understanding of SSBs. Frequency and weighted proportion were used for description. With individual as level 1 and resident council (village council) as level 2, a two-level logistic regression model was applied to examine the influencing factors. A null model was used to determine whether the two-level logistic regression model was appropriate. Results The knowledge awareness rate of SSBs was 57.0% among the Chinese residents aged 18-64 years in 2021. The knowledge point with the lowest correct rate was "It is best to consume no more than 25 grams of added sugar per day" (22.6%), while the one with the highest correct rate was "Excessive intake of SSBs can increase the risk of obesity and diabetes" (81.1%). The results of the null model showed that SSBs knowledge level had a clustering effect at resident council (village council) level (t=25.00, P<0.0001), so a two-level model fit better than a one-level model. The results of the two-level logistic model revealed that residents who were female (OR=1.14, 95%CI: 1.11, 1.18) or working in medical and health (OR=1.36, 95%CI: 1.27, 1.45) and education institutions (OR=1.16, 95%CI: 1.07, 1.24) had a higher knowledge level compared to males or residents of other occupations. The knowledge level was lower among residents in central (OR=0.87, 95%CI: 0.77, 0.97) and western (OR=0.85, 95%CI: 0.75, 0.94) areas than in eastern areas. Those with chronic diseases (OR=0.81, 95%CI: 0.78, 0.84) and who did not know if they had a chronic disease (OR=0.75, 95%CI: 0.72, 0.78) had a lower knowledge level than those without chronic diseases. Compared with 18-24 years, the knowledge level was higher in ages 35-44 years (OR=1.07, 95%CI: 1.02, 1.12) and lower in ages 55-64 years (OR=0.92, 95%CI: 0.86, 0.97), and not different from the ages 25-34 years and 45-54 years. The knowledge level increased with the level of education, the trend was statistically significant (P＜0.001). Conclusion Only about half of Chinese adults aged 18-64 years had a basic understanding of SSBs in 2021. The awareness rate of added sugar intake was low in particular. The knowledge levels of male, central and western, or less educated populations were even lower. Awareness of the negative health outcomes of SSBs was high among the population.

The kidney is the body's most important organ and the protein components in urine could be detected for diagnosing certain diseases. The amount of IgG protein in urine could be used to determine the degree of kidney function damage. IgG protein in human urine was detected by vertical flow paper-based microfluidic chip, double-antibody sandwich immunoreaction, and cell phone image processing. The results showed that using an IgG antibody concentration of 500 μg/mL and a gold standard antibody concentration of 100 μg/mL, the image signal showed a good linear relationship in the range of IgG concentration of 0.2-3.2 μg/mL, with R²=0.973 3 achieved. A complete set of detection devices were designed and the detection method showed good non-specificity.
