Objective To investigate the expression of nuclear factor-κB (NF-κB) and p53 up-regulated modulator of apoptosis (PUMA) in acute lung injury (ALI) induced by severe acute pancreatitis (SAP), and the therapeutic role of proline dithiocarbamate (PDTC). Method SD rats weighed 200~ 250 g were randomly(random number) divided into sham operation group (A group, n = 18), ALI group (B group, n = 18) and PDTC treatment group (C group, n = 18). The model of SAP was eastablished by injecting 1 mL/kg of sodium tauarocholate into the pancreatic capsule of the rats in B group and C group. The model rats in C group were treated with PDTC one hour after modeling. Six rats of each group were sacrificed 6 h,12 h, and 24 hours after modeling. The histopathological changes in lung and pancreas were observed. The levels of NF-κB p65 and PUMA in lung were detected by using Western blotting, and the expressions of bcl-2, bax and caspase-3 mRNA in the lung were detected by using RT-PCR. The lung tissue was taken for examination under transmission electron microscope. TUNEL was used for detection of apoptotic alveolar epithelial cells. Results Six to 24 hours after modeling, the pathological scores in lung of ALI group were significantly higher than those of control group and PDTC group after sodium taurocholate injection ( P < 0.05). The levels of NF-κB p65 and PUMA, and the expressions of bax and caspase3 mRNA in ALI group at different intervals were higher than those in control group and PDTC group ( P < 0.05),whereas the expression of bcl-2 mRNA in ALI group was lower than that in control group and PDTC group ( P <0.05). The NF-κB p65 was correlated closely and positively with PUMA ( r= 0.987, P < 0.01). Higher activity of caspase-3 acrtive units was seen in ALI group than that in control group and PDTC group ( P < 0.05). The microvilli disappeared in ALI group 24 hours later. The apoptosis index in ALI group was higher than that in control group and PDTC group ( P < 0.05). Conclusions The apoptosis of alveolar epithelial cells of rats in ALI group is caused by PUMA activated by NF-κB. PDTC treatment can inhibit apoptosis of alveolar epithelial cells of rats in ALI group by inhibiting the activation of NF-κB.

Green tea or green tea extract (GT/GTE) has been demonstrated to reduce insulin resistance and improve glycemic control. However, evidence for this health beneficial effect is inconsistent. This systematic review evaluated the effect of GT/GTE on insulin resistance and glycemic control in people with pre-diabetes/type 2 diabetes mellitus (T2DM). Ovid MEDLINE, Embase, AMED, Web of Science, and the Cochrane Library were searched up to April 2017 for randomised controlled trials of participants with pre-diabetes or T2DM, where the intervention was GT/GTE. Meta-analysis was performed to assess the standardised mean difference (SMD) in biomarkers of insulin resistance and glycemic control between GT/GTE and placebo groups. Six studies (n=382) were pooled into random-effects meta-analysis. Overall, no differences were found between GT/GTE and the placebo for glycosylated hemoglobin (HbA1c: SMD, −0.32; 95% confidence interval [CI], −0.86 to 0.23), homeostatic model assessment for insulin resistance (HOMA-IR: SMD, 0.10; 95% CI, −0.17 to 0.38), fasting insulin (SMD, −0.25; 95% CI, −0.64 to 0.15), and fasting glucose (SMD, −0.10; 95% CI, −0.50 to 0.30). No evidence support the consumption of GT/GTE could reduce the levels of HbA1c, HOMA-IR, fasting insulin, or fasting glucose in people with pre-diabetes/T2DM. However, the studies included were small and of varying quality.

OBJECTIVES:
This study examined the associations between adverse childhood experiences (ACEs) and diabetes within a social-ecological framework, incorporating personal and environmental unfavorable conditions during childhood from family, school, and community contexts.
METHODS:
Data were obtained from the China Health and Retirement Longitudinal Study (2014 life history survey and 2015 survey), including 9,179 participants aged ≥45 years. ACEs were collected through self-report questionnaires, and participants were categorized based on the number of distinct ACEs experienced (0, 1, 2, 3, or ≥4 ACEs). Diabetes was defined by biomarkers, self-reported diagnosis, and treatment status. Logistic regression was conducted to explore the associations between ACEs and diabetes. Subgroup analyses were conducted by gender, age, and obesity status.
RESULTS:
Compared with participants without ACEs, those exposed to any ACE (odds ratio [OR], 1.19; 95% confidence interval [CI], 1.01 to 1.40), 3 ACEs (OR, 1.32; 95% CI, 1.07 to 1.62) and ≥4 ACEs (OR, 1.29; 95% CI, 1.07 to 1.56) had an increased risk of diabetes. For each additional ACE, the risk of diabetes increased by about 5%. Regarding the source of ACEs, those originating from the family (OR, 1.23; 95% CI, 1.08 to 1.41) were associated with diabetes. In terms of specific ACE types, family members with substance abuse (OR, 1.23; 95% CI, 1.01 to 1.52), emotional abuse (OR, 1.28; 95% CI, 1.12 to 1.46), and poor parental relationship (OR, 1.25; 95% CI, 1.09 to 1.43) were associated with diabetes.
CONCLUSIONS
ACEs, particularly those originating from the family, were associated with diabetes. Interventions aimed at preventing and mitigating ACEs are essential for the early prevention of diabetes.

OBJECTIVES:
This study aimed to investigate the associations of obesity phenotypes with hypertension stages, phenotypes, and transitions among middle-aged and older Chinese.
METHODS:
Using the 2011-2015 waves of the China Health and Retirement Longitudinal Study, we conducted a cross-sectional analysis included 9,015 subjects and a longitudinal analysis included 4,961 subjects, with 4,872 having full data on the hypertension stage and 4,784 having full data on the hypertension phenotype. Based on body mass index and waist circumstance, subjects were categorized into 4 mutually exclusive obesity phenotypes: normal weight with no central obesity (NWNCO), abnormal weight with no central obesity (AWNCO), normal weight with central obesity (NWCO), and abnormal weight with central obesity (AWCO). Hypertension stages were classified into normotension, pre-hypertension, stage 1 hypertension, and stage 2 hypertension. Hypertension phenotypes were categorized as normotension, pre-hypertension, isolated systolic hypertension (ISH), isolated diastolic hypertension (IDH), and systolic-diastolic hypertension (SDH). The association between obesity phenotypes and hypertension was estimated by logistic regression. A comparison between different sexes was conducted by testing the interaction effect of sex.
RESULTS:
NWCO was associated with normal→stage 2 (odds ratio [OR], 1.95; 95% confidence interval [CI], 1.11 to 3.42), maintained stage 1 (OR, 1.62; 95% CI, 1.14 to 2.29), and normal→ISH (OR, 1.39; 95% CI, 1.05 to 1.85). AWCO was associated with normal→stage 1 (OR, 1.75; 95% CI, 1.40 to 2.19), maintained stage 1 (OR, 2.77; 95% CI, 2.06 to 3.72), maintained stage 2 (OR, 2.80; 95% CI, 1.50 to 5.25), normal→ISH (OR, 1.56; 95% CI, 1.20 to 2.02), and normal→SDH (OR, 2.54; 95% CI, 1.72 to 3.75). An interaction effect of sex existed in the association between obesity phenotypes and hypertension stages.
CONCLUSIONS
This study highlights the importance of various obesity phenotypes and sex differences in hypertension progression. Tailored interventions for different obesity phenotypes may be warranted in hypertension management, taking into account sex-specific differences to improve outcomes.

Objective To investigate the relationship between exposure to famine in early life stage and hypertension phenotype and grade in middle and old age. Methods People born between 1951 and 1965 in the 2015 China Health and Elderly Care Follow-up Survey were included in the study, and were divided into unexposed group, fetal exposed group, childhood exposed group and adolescent exposed group according to the time of famine occurrence and birth year of the participants. Logistic regression model was used to explore the effects of different famine exposure periods in early life stage on hypertension classification (including normal high value, grade I, grade II and grade III) and phenotype (including isolated systolic hypertension[ISH], isolated diastolic hypertension [IDH] and combined systolic and diastolic hypertension [SDH]). Results Compared with unexposed group, fetal famine exposure (OR=1.59, 95% CI :1.10-2.30), childhood famine exposure (OR=1.67, 95% CI :1.04-2.70) and adolescent famine exposure (OR=3.42, 95% CI : 2.51-4.66) were the risk factors for ISH. Only famine exposure during adolescence (OR=1.54, 95% CI: 1.07-2.21) was a risk factor for SDH. In addition, fetal famine exposure (OR=1.41, 95% CI: 1.05-1.89) and adolescent famine exposure (OR=2.22 , 95% CI: 1.71-2.88) were risk factors for developing grade I hypertension. Famine exposure in childhood (OR=2.45, 95% CI: 1.21-4.94) and famine exposure in adolescence (OR=2.45, 95% CI: 1.44-4.19) were risk factors for grade 2 hypertension. Conclusion Famine exposure in early life stage was associated with the phenotype and grade of hypertension. Therefore, balanced nutrition in early life is important to prevent hypertension in adulthood.

Objective:
To investigate the diagnosis and treatment for enterocutaneous fistula (ECF) in China, and to explore the prognostic factors of ECF.
Methods:
A multi-center cross-sectional study was conducted based on the Registration System of Chinese Gastrointestinal Fistula and Intra-Abdominal Infections to collect the clinical data of ECF patients from 54 medical centers in 22 provinces/municipalities from January 1, 2018 to December 31, 2018. The clinical data included patient gender, age, length of hospital stay, intensive care unit (ICU) admission, underlying diseases, primary diseases, direct causes of ECF, location and type of ECF, complications, treatment and outcomes. All medical records were carefully filled in by the attending physicians, and then re-examined by more than two specialists. The diagnosis of ECF was based on the clinical manifestations, laboratory/imaging findings and intraoperative exploration.
Results:
A total of 1521 patients with ECF were enrolled, including 1099 males and 422 females, with a median age of 55 years. The top three primary diseases of ECF were malignant tumors in 626 cases (41.2%, including 540 gastrointestinal tumors, accounting for 86.3% of malignant tumors), gastrointestinal ulcers and perforations in 202 cases (13.3%), and trauma in 157 cases (10.3%). The direct causes of ECF were mainly surgical operation in 1194 cases (78.5%), followed by trauma in 156 (10.3%), spontaneous fistula due to Crohn
