Objective: To evaluate the effect of "healthy eating plate" based dietary management on diabetic inpatients. Methods: The patients with type 2 diabetes mellitus (T2DM) admitted to Daishan First People's Hospital from November 2019 to November 2020 were selected and randomly divided into two groups. The intervention group was given "healthy eating plate" based dietary management, while the control group was given routine dietary management. Demographic data and physical examination results were collected. Fasting blood glucose (FPG), glycosylated hemoglobin (HbA1c), triglyceride (TG) and total cholesterol (TC) were detected at admission, discharge and 3 months after discharge, and compared between the two groups by covariance and generalized estimating equation. Results: here were 52 patients aged (55.83±9.67) years in the intervention group, with 29 (55.77%) males and 23 (44.23%) females. There were 53 patients aged (57.54±11.09) years in the control group, with 32 (60.38%) males and 21 (39.62%) females. There were no significant differences in FPG, HbA1c, TG and TC levels between two groups at discharge (P>0.05). The level of HbA1c in the intervention group was significantly lower than that in the control group at 3 months after discharge (P<0.05); there were no significant differences in FPG, TG and TC levels (P>0.05). Conclusion The "healthy eating plate" based dietary management can better control the blood glucose of diabetic patients, and can help maintain the dietary treatment. It is worthy of promotion in diabetic patients.

Objective:To explore the association between sleep duration, sleep quality and the prevalence of hypertension in the elderly aged 65 years and above.Methods:This study was conducted among the elderly in communities in Yiwu, China from April to July, 2019, and participants were recruited through physical examination in the hospital. Face-to-face interview was performed to obtain basic information. Sleep duration and sleep quality were evaluated by Pittsburgh Sleep Quality Index (PSQI). Associations between sleep duration, sleep quality and hypertension were evaluated by multivariate logistic regression analysis.Results:A total of 3 169 elderly persons, aged ≥65 years old, were included in the study. The overall prevalence of hypertension was 50.8%. The elderly with very poor sleep quality and short sleep duration accounted for 22.4% and 28.5%, respectively. After adjusting for demographic characteristics, socioeconomic status, lifestyle and health status, the OR of hypertension for the elderly with very poor sleep quality was 1.42 (95% CI: 1.12-1.80) compared with those with very good sleep quality. Compared with the elderly with sleep duration of 6-7 h a night, the OR of hypertension for those with sleep duration <6 h was 1.37 (95% CI: 1.15-1.65). As the sleep quality decreased, the risk for hypertension increased. An U-shaped association was found between sleep duration and risk of hypertension. Subgroup analyses showed that this association existed in both men and women, but only significant in the elderly aged <75 years. Conclusion:Poor sleep quality and short sleep duration were associated with risk for hypertension in the elderly.

Objective:To explore the influencing factors of job burnout of medical staff and provide reference for the formulation of intervention measures.Methods:From November to December, 2018, a questionnaire survey was conducted among medical staff in a general hospital by using the research design of the current situation survey. A total of 1193 questionnaires were distributed and 939 questionnaires were returned, with a recovery rate of 78.7%, including 891 valid questionnaires and an effective recovery rate of 94.9%. Social support rating scale (SSRs) was used to evaluate social support, and Maslach Burnout Scale (MBI-GS) was used to evaluate job burnout. Single factor analysis was performed by chi square test and Fisher exact probability method. To explore the influencing factors of job burnout by using disordered multi classification logistic.Results:The average age was (27.47 ± 4.22) years old, female accounted for 71.5% (637/891) . The total physical examination rate of job burnout was 46.6%. The scores of emotional exhaustion, cynicism and decreased sense of achievement were (10.10±3.75) , (6.14±3.43) , (17.91±4.13) respectively. Multiple logistic regression analysis showed that, compared with the non detected job burnout, the young, working for 1-3 years, average sleep ≤6 hours, and poor social support were more likely to have mild job burnout ( OR=0.91, 0.40, 2.25, 2.38, P<0.05) ; female, high night shift frequency in the past year, average sleep ≤6 h. Those with poor social support were more likely to have moderate to severe job burnout ( OR=1.59, 2.94, 4.01, 2.40, 3.66, P<0.05) . Conclusion:Corresponding measures should be taken to reduce job burnout and improve work efficiency.

Objective:To evaluate and improve the performance of the newborn screening program for primary carnitine deficiency (PCD) based on tandem mass spectrometry and to investigate the incidence of PCD and molecular characteristics of SLC22A5 gene in Guangzhou.Methods:A total of 200 180 neonates born in Guangzhou from 2015 to 2019 were enrolled into the newborn screening program for PCD by tandem mass spectrometry at Guangzhou Newborn Screening Center. The positive results of screening for PCD was defined as free carnitine (C0) less than 10 μmol/L with decreased acylcarnitine species in dried blood spots of three to seven days after birth. Screen-positive newborns and their mothers were recalled for another blood spot sample. The diagnosis was confirmed based on decreased levels of C0 and acylcarnitine species in recalled blood spots and genetic analysis in SLC22A5 gene sequencing. The utility of using the sum of propionylcarnitine and palmitoylcarnitine (C3+C16) as a biomarker for acylcarnitine species in newborn screening was retrospectively evaluated. The levels of C0 and (C3+C16) at first screening were compared between newborns with PCD and newborns born to mothers with PCD by independent t test. The variant spectrum and known pathogenic variants carrier rate of SLC22A5 in 2 395 healthy children in Guangzhou Women and Children′s Medical Center through whole exon sequencing were analyzed. Results:Among 200 180 neonates, 239 (0.12%) cases were screen-positive for PCD. A total of 37 patients including 15 newborns and 22 mothers had confirmed PCD. The incidence of PCD was 1/13 345 in newborns and 1/9 099 in mothers, respectively. The positive predictive value of this program was 15.5%. Taking cutoff values of C0<8.5 μmol/L or C0 8.5~9.9 μmol/L with (C3+C16)<2 μmol/L, the number of screen-positive cases would be reduced from 810 to 224 without additional false negative case, when compared with cutoff value C0<10 μmol/L only. Both levels of C0 and (C3+C16) at first screening were not significant difference between newborns with PCD and newborns born to mothers with PCD ((6.2±2.4) vs. (5.0±1.8) μmol/L, (1.4±0.4) vs. (1.2±0.5) μmol/L, t=3.826, 0.326; P=0.058, 0.572). Seven PCD mothers experienced moderate fatigue and dizziness in the morning. One of them presented with cardiomyopathy in pregnancy. Genetic analysis of the SLC22A5 gene showed that p.S467C, p.F17L, p.R254X were the three most common variants in newborns with PCD. In PCD mothers and healthy children, the p.S467C, p.F17L and R399W were the three most common whereas the severe variant p.R254X was rare. The population carrier rate for pathogenic variants was 1 in 65 and the estimated incidence of PCD was about 1/16 500. Conclusions:Newborn screening can detect PCD both in newborns and mothers. Adding a quantitative biomarker (C3+C16) <2 μmol/L into the newborn screening program can improve the PCD screen performance. The severe variant p.R253X was common in PCD newborns but rare in PCD mothers and healthy children, indicating that the current screening program maybe failed to detect all PCD newborns and under-estimated the incidence rate of PCD in Guangzhou.

Objective To evaluate the influence of atopy on the prognosis of juvenile-onset systemic lupus erythematosus (JSLE).Methods The study was performed on 60 cases with JSLE diagnosed at the Department of Pediatrics,Renji Hospital Affiliated to School of Medicine of Shanghai Jiaotong University from October 2005 to April 2015.These patients were enrolled by mixed cohort study and subdivided into atopic group(26 cases) or non-atopic group(34 cases).The clinical and laboratory data of the disease onset,disease assessment scores,medications during follow-ups and remission/flare of the disease were recorded and analyzed to compare the difference between 2 groups.Results (1) The systemic lupus erythematosus disease activity index (SLEDAI) score [(17.080 ± 5.628) scores vs (12.590 ± 4.856) scores],anti-double-stranded DNA (anti-dsDNA) [(62.590 ± 43.602) IU/mL vs (40.230 ±30.189) IU/mL],erythrocyte sedimentation rate (ESR) [(59.150 ± 40.315) mm/1 h vs (40,350 ± 31.865)mm/1 h] were significantly elevated at onset in the atopic group compared with non-atopic controls (all P ＜ 0.05),while the complement C3[(0.450 ±0.218) g/L vs(0.640 ±0.333) g/L],C4 [(0.047 ±0.024) g/L vs(0.116 ±0.172) g/L] in atopic group was lower than those in the non-atopic group (all P ＜ 0.05).(2)During the follow ups of 1 and 6 months to 1 year,the JSLE patients with atopy always had higher SLEDA1 score compared with the non atopic controls(all P ＜ 0.05).(3)For medications,the daily cumulative glucocorticoid dose received by patients in the atopic group were larger than that of the non-atopic group,and the number of immunosuppressive agents used in the atopic group was more than that in the non-atopic controls (P ＜ 0.05).(4) During the 1-year follow-up,the rate of disease relapse in the atopic group was higher than that in the non-atopic group and the atopic group also needed much more time to reach disease remission (P ＜ 0.05).Conclusion JSLE patients combined with atopy may have an adverse influence on the prognosis of JSLE.

The aim of the study was to construct a recombinant adenovirus overexpression vector for Sterol Regulatory Element Binding Protein-1 (SREBP-1) of Xinong Saanen dairy goat, and to detect its effect on genes related to fatty acid metabolism in goat mammary epithelial cells, to establish foundation for further study of its roles in metabolism of fatty acid synthesis and lactation. First, we designed primers based on the SREBP-1 gene sequence in GenBank for PCR amplification and inserted the sequence into shuttle vector pAdTrack-CMV. The recombinant plasmid pAdTrack-CMV-SREBP-1 linearized by Pme I was transformed into E. coli BJ5183 competence cell containing the backbone vector pAdEasy-1 to obtain recombinant vector pAd-SREBP-1 by homologous recombination. pAd-SREBP-1 was linearized by Pac I and transfected into HEK 293 cell. Then we infected goat mammary epithelial cells with recombinant adenovirus which was packaged in HEK 293 cell line. The results showed that the recombinant adenovirus vector containing SREBP-1 was successfully constructed, and the titer of virus was 10(9) U/mL. Compared with the control group, mRNA level of SREBP-1 increased by about 15 times after infected for 48 h and 30 times after infected for 72 h. Fatty acid synthase (FASN) and Acetyl-CoA carboxylase (ACC) was upregulated by almost 2 times. The expression level of Peroxisome proliferator activated receptorgamma (PPARgamma) increased by 1.5 times. Liver X receptoralpha (LXRalpha) and Adipose triglyceride lipase (ATGL) upregulated by 1.2 times compared with that of control. But Stearoyl-coenzyme A desaturase (SCD) had no obvious change. In conclusion, SREBP-1 can activate the expression of genes related to fatty acid synthesis in mammary epithelial cells of Xinong Saanen dairy goat, demonstrated a regulatory function on the fatty acid metabolism in goat mammary gland.

Objective To investigate the effect of smoking and smoking cessation on the phosphorylation of IKK-β in type 2 diabetic rats. Methods Forty-two six-week-old Wistar rats were randomly divided into 4 groups: normal control(NC, n =7), diabetes control (DC, n =7), diabetes with smoking (DS, n = 14) and diabetes with smoking cessation(SC, n = 14). Rats in DS and SC groups were further assigned randomly into 8w and 12w subgroups. DS group was given passive smoking twice a day for 8 or 12 weeks, while SC group ceased passive smoking for 4 weeks after 8 or 12 weeks of smoking . Western blot method was used to detect the level of IKK-13 phosphorylation in skeletal muscle. Results Compared with the NC group,the phosphorylation of IKK-β protein in DC group was increased (0. 16±0. 05 vs 0. 30±0. 08, P < 0. 01). There was an increasing trend with the phosphorylation level of IKK-β in the DS (8w) subgroup, but there was no statistical difference between the DC group and SC(8w) subgroup (0. 40±0. 09 vs 0. 30±0. 08,0. 36±0. 10, P >0. 05). The phosphorylation level of IKK-β in DS(12w) group increased obviously, being significantly higher than that in the DC group and SC (12w) subgroup(0. 74 ± 0. 11 vs 0.30±0.08,0.35±0.07,P < 0.01). Conclusion With the prolongation of smoking duration, the phosphorylation of IKK-β in type 2 diabetic rats increased. After smoking cessation, the phosphorylation of IKK-β decreased. The phosphorylation of IKK-β may be involved in the mechanism by which smoking causes type 2 diabetes.

OBJECTIVE To study the feature of liver disease and liver failure complicated with fungous infection. METHODS The patients with liver disease complicated with fungous infection were collected form 1986 to 2005. The time was divided into four stages:from 1986 to 1990,from 1991 to 1995,from 1996 to 2000 and from 2001 to 2005. All patients with liver failure complicated with fungous infection in different stages were investigated for the incidence,the use of antibiotics and corticosteroids,the category and site of fungous infection and prognosis. RESULTS End-stage liver disease accounted for 82.6% and HBV infection was the main etiology in 475 cases of fungous infection. Fungous infection occurred mainly in hospital. Hospital acquired infection and community acquired infection were similar in different stages. The use of antibiotics and corticosteroids accounted for 88.8% and 48% in all patients before fungous infection,respectively. The use of antibiotics had no difference and the use of corticosteroids decreased in different stages. Candida were the main infection strains and the lungs and pharynx oralis were the main infection sites. The rate of healing and improvement of fungous infection and underlying diseases increased year by year. Healing and improvement rate of underlaying disease positively correlated with that of fungous infection. CONCLUSIONS End-stage liver disease patients are susceptible to fungous infection and Candida are the common infection strains. Lungs and pharynx oralis are the common infection sites. Anti-fungous therapy is important in the treatment of liver failure complicated with fungous infection.

OBJECTIVE To study clinical characteristics of liver failure with fungal infections in the elderly patients and risk factors associated with treatment failure.METHODS Eighty four elderly patients with liver failure followed by fungal infections since 1986 were divided into two groups: effective group and ineffective group.RESULTS The common pathogens were Candida albicans(58.33%),Aspergillus fumigatus(9.52%) and Candida tropicalis(8.33%).The lungs(43.88%),mouth(32.65%),intestinal tract(9.18%) and blood(5.10%) were the main sites of fungal infection.Among them after treatment,35 cases(41.67%) were effective compared with 49 cases(58.33%) ineffective.The risk factors for treatment failure included age,complication with multiple organ dysfunction syndrome(MODS) and aspergillosis.In multivariate analysis,we found MODS in patients was an independent factor in predicting the prognosis.CONCLUSIONS To improve the treatment outcome,important measures include preventing infection,enhancing the treatment of liver failure,monitoring and supporting multiple organs: heart,brain,lungs and kidneys,and promptly rational administration of antifungal agents in elderly patient with liver failure.
