A 63-year-old maintenance hemodialysis patient with diabetic nephropathy was reported. The patient was incapacitated, with systemic edema, heart failure, severe anemia, malnutrition, gastrointestinal bleeding, and intractable hypertension. We adopted integrated management methods such as "multidisciplinary collaboration" and "doctor-patient collaboration": by accurately controlling the volume load to protect the residual renal function, taking into account the treatment of underlying diseases and complications, integrating the clinical parameters of dialysis and the interdialysis period, and combining the subjective clinical symptom score with the objective index analysis, the objectives of effectively controlling the dry weight of patients, alleviating complications, improving nutrition and protecting the residual renal function were finally achieved. The quality of life of the patient had been significantly improved.

Pulmonary fibrosis (PF) is the pathological structure of incurable fibroproliferative lung diseases that are attributed to the repeated lung injury-caused failure of lung alveolar regeneration (LAR). Here, we report that repetitive lung damage results in a progressive accumulation of the transcriptional repressor SLUG in alveolar epithelial type II cells (AEC2s). The abnormal increased SLUG inhibits AEC2s from self-renewal and differentiation into alveolar epithelial type I cells (AEC1s). We found that the elevated SLUG represses the expression of the phosphate transporter SLC34A2 in AEC2s, which reduces intracellular phosphate and represses the phosphorylation of JNK and P38 MAPK, two critical kinases supporting LAR, leading to LAR failure. TRIB3, a stress sensor, interacts with the E3 ligase MDM2 to suppress SLUG degradation in AEC2s by impeding MDM2-catalyzed SLUG ubiquitination. Targeting SLUG degradation by disturbing the TRIB3/MDM2 interaction using a new synthetic staple peptide restores LAR capacity and exhibits potent therapeutic efficacy against experimental PF. Our study reveals a mechanism of the TRIB3-MDM2-SLUG-SLC34A2 axis causing the LAR failure in PF, which confers a potential strategy for treating patients with fibroproliferative lung diseases.

Conclusion Current evidence shows that biliary etiology and alcoholic etiology are unique influencing factors for ANP in the Eastern population, while Ranson score is a unique influencing factor in the Western population.BMI and extent of necrosis ≥30% are unique influencing factors for IPN in the Eastern population, while alcoholic etiology is a unique influencing factor in the Western population.

The cell cycle inhibitor P21 has been implicated in cell senescence and plays an important role in the injury-repair process following lung injury. Pulmonary fibrosis (PF) is a fibrotic lung disorder characterized by cell senescence in lung alveolar epithelial cells. In this study, we report that P21 expression was increased in alveolar epithelial type 2 cells (AEC2s) in a time-dependent manner following multiple bleomycin-induced PF. Repeated injury of AEC2s resulted in telomere shortening and triggered P21-dependent cell senescence. AEC2s with elevated expression of P21 lost their self-renewal and differentiation abilities. In particular, elevated P21 not only induced cell cycle arrest in AEC2s but also bound to P300 and β-catenin and inhibited AEC2 differentiation by disturbing the P300-β-catenin interaction. Meanwhile, senescent AEC2s triggered myofibroblast activation by releasing profibrotic cytokines. Knockdown of P21 restored AEC2-mediated lung alveolar regeneration in mice with chronic PF. The results of our study reveal a mechanism of P21-mediated lung regeneration failure during PF development, which suggests a potential strategy for the treatment of fibrotic lung diseases.

Background Long working hours (LWH) and shift work are harmful to the physical and mental health of occupational groups. Objective To understand the status quo of LWH and shift work of migrant workers in Shanghai, and to analyze the influence of the above two factors on sleep of the population. Methods From July to September 2018, a cross-sectional survey using questionnaires was conducted among 3215 in-service employees at seven workplaces with more than 300 employees in six selected districts of Shanghai using multi-stage random sampling method. A total of 2976 valid questionnaires were collected, with a valid response rate of 92.6%. The questionnaires included general demographic characteristics, personal health behavior, work-related factors, weekly working hours, shift work, and sleep. Univariate analysis and logistic regression analysis were used to investigate the relationships of LWH and shift work with sleep, and an interaction item was included to evaluate potential interaction between LWH and shift work. Result The average age of the subjects was (30.98±9.49) years old, the male to female ratio was 1∶1.20, and 2382 workers were reported without local residency (80.0%). Among the migrant workers, the average weekly working hours was (57.23±13.14) h, the proportions of LWH (weekly working hours>40 h), extra LWH (weekly working hours>55 h), and shift work were 80.6% (1919/2382), 60.3% (1436/2382), and 25.4% (600/2366), respectively, all above were significantly higher than those of local workers. The prevalence rates of insomnia and lack of sleep among the migrant workers were 46.3% (1091/2356) and 25.4% (597/2354), respectively. The results of logistic regression model showed that after adjusting demographic characteristics such as gender, age, education level, and monthly income, as well as occupation and personal health behavior, compared with working hours ≤40 h per week, working 55-60 h per week was a risk factor for insomnia of migrant workers (OR=1.33, 95%CI: 1.02-1.72), while working >60 h per week was a risk factor for both insomnia (OR=1.37, 95%CI: 1.05-1.78) and insufficient sleep (OR=1.73, 95%CI: 1.28-2.35) of migrant workers. Shift work was only associated with insomnia (OR=1.37, 95%CI: 1.11-1.69). Meanwhile, working hours>60 h per week and shift work had an interaction effect on insomnia of migrant workers (OR=2.35, 95%CI: 1.20-4.60). Conclusion LWH and shift work are prominent among migrant workers, and there is an interaction between LWH and shift work with insomnia.

Background The community is the main place for people's daily activities. A livable environment will improve the subjective well-being of residents. Objective To understand the current status of subjective well-being of residents in Pudong, Shanghai, and explore the impact of community environmental factors on residents' subjective well-being. Methods Using quota sampling, 6000 permanent residents from 12 sub-districts or towns in Pudong, Shanghai were selected to participate in an questionnaire survey. The questionnaire included three parts: participants' basic information, community environmental factors (neighborhood aesthetics, fitness environment, public service and security, natural environment), and subjective well-being. Using a multiple regression model, the influence of community environmental factors on the subjective well-being of residents was analyzed. Results A total of 5887 questionnaires were recovered, and the valid recovery rate was 98.1%. The subjective well-being score of the survey respondents was (7.03±1.61) points. There was no statistical difference in the subjective well-being score of study subjects of different gender and marital status groups; while those with different ages, education levels, occupations, and self-evaluated economic status showed statistical differences in their subjective well-being score (P<0.05). The multiple logistic regression analysis results showed that after controlling general demographic characteristics, with the low level as the control group (according predetermined cut-off values of 33.3% and 66.7%, the community environmental factors were divided into high-, medium-, and low-level groups), the OR values of subjective well-being of the high- and medium-level neighborhood aesthetics groups were 1.393 (95%CI: 1.173-1.654) and 1.235 (95%CI: 1.080-1.412); the OR values of the high- and medium-level fitness environment groups were 2.297 (95%CI: 1.929-2.734) and 1.349 (95%CI: 1.166-1.560); the OR values of the high- and medium-level public service and security groups were 1.101 (95%CI: 0.943-1.285) and 1.039 (95%CI: 0.905-1.193); the OR values of the high- and medium-level natural environment groups were 4.248 (95%CI: 3.321-5.434) and 1.652 (95%CI: 1.374-1.986), respectively. Conclusion Community environment factors could affect residents' subjective well-being, and good neighborhood aesthetics, fitness environment, natural environment have positive effects.

Background::The risk for chronic kidney disease (CKD) is influenced by genetic predisposition, sex, and lifestyle. Previous research indicates that coffee is a potentially protective factor in CKD. The current study aims to investigate whether sex disparity exists in the coffee–CKD association, and whether genetic risk of CKD or genetic polymorphisms of caffeine metabolism affect this association.Methods::A total of 359,906 participants from the UK Biobank who were enrolled between 2006 and 2010 were included in this prospective cohort study, which aimed to estimate the hazard ratios for coffee intake and incident CKD using a Cox proportional hazard model. Allele scores of CKD and caffeine metabolism were additionally adjusted for in a subsample with qualified genetic data ( n = 255,343). Analyses stratified by genetic predisposition, comorbidities, and sex hormones were performed. Tests based on Bayesian model averaging were conducted to ascertain the robustness of the results. Results::Coffee was inversely associated with CKD in a dose-dependent manner. The effects of coffee did not differ across different strata of genetic risk for CKD, but were more evident among slower genetically predicted caffeine metabolizers. Significant sex disparity was observed ( P value for interaction = 0.013), in that coffee drinking was only associated with the risk reduction of CKD in females. Subgroup analysis revealed that testosterone and sex hormone-binding globulin (SHBG), but not estradiol, modified the coffee–CKD association. Conclusions::In addition to the overall inverse coffee–CKD association that was observed in the general population, we could also establish that a sex disparity existed, in that females were more likely to experience the benefit of the association. Testosterone and SHBG may partly account for the sex disparity.

Median arcuate ligament syndrome(MALS)is compression of the celiac trunk by the median arcuate ligament.Median arcuate ligament release is the corner stone for the surgical treatment of MALS.Open surgery,laparoscopic surgery,and robot-assisted surgery have been developed,among which laparoscopic surgery has been proposed as the preferred approach in view of its minimal trauma and short hospital stay.Auxiliary celiac plexus neurolysis could further alleviate the patient's discomfort.Moreover,vascular reconstitution is of vital importance in the case of persistent stenosis in the celiac artery despite of median arcuate ligament decompression.Vascular reconstruction has satisfactory long-term patency rate,while endovascular treatment is less invasive.This article aims to summarize the consensuses and advances and shed light on the surgical treatment of MALS.

This commentary reviews the updates on laser and aesthetic medicine in recent two years and provide the evidence-based conclusion for recent laser treatments for our patients. Progress has been made in the following respects. Combined laser or drug treatment is better than single treatment for hypertrophic scar. The picosecond laser has recently been shown to be safe and effective for Asian atrophic acne scars. Picosecond laser with or without diffractive lens array (DLA) lens has been proved safe and effective for melasma. The effect of port-wine stains could only be increased by 5%-10% after 10 times of pulsed dye laser (PDL), so that more sessions has less benefit. Radiofrequency and focused ultrasound are still the mainstream devices for photoaging, but recently it has been proved that picosecond laser and CO 2 injection are also safe and effective. Nonablative laser is still the main device for improving facial pores and stretch marks.
