BACKGROUND: While emotional distress, encompassing anxiety and depression, has been associated with negative clinical outcomes, its impact across various clinical departments and general hospitals has been less explored. Previous studies with limited sample sizes have examined the effectiveness of specific treatments (e.g., antidepressants) rather than a systemic management strategy for outcome improvement in non-psychiatric inpatients. To enhance the understanding of the importance of addressing mental health care needs among non-psychiatric patients in general hospitals, this study retrospectively investigated the impacts of emotional distress and the effects of early detection and management of depression and anxiety on hospital length of stay (LOS) and rate of long LOS (LLOS, i.e., LOS >30 days) in a large sample of non-psychiatric inpatients. METHODS: This retrospective cohort study included 487,871 inpatients from 20 non-psychiatric departments of a general hospital. They were divided, according to whether they underwent a novel strategy to manage emotional distress which deployed the Huaxi Emotional Distress Index (HEI) for brief screening with grading psychological services (BS-GPS), into BS-GPS ( n = 178,883) and non-BS-GPS ( n = 308,988) cohorts. The LOS and rate of LLOS between the BS-GPS and non-BS-GPS cohorts and between subcohorts with and without clinically significant anxiety and/or depression (CSAD, i.e., HEI score ≥11 on admission to the hospital) in the BS-GPS cohort were compared using univariable analyses, multilevel analyses, and/or propensity score-matched analyses, respectively. RESULTS: The detection rate of CSAD in the BS-GPS cohort varied from 2.64% (95% confidence interval [CI]: 2.49%-2.81%) to 20.50% (95% CI: 19.43%-21.62%) across the 20 departments, with a average rate of 5.36%. Significant differences were observed in both the LOS and LLOS rates between the subcohorts with CSAD (12.7 days, 535/9590) and without CSAD (9.5 days, 3800/169,293) and between the BS-GPS (9.6 days, 4335/178,883) and non-BS-GPS (10.8 days, 11,483/308,988) cohorts. These differences remained significant after controlling for confounders using propensity score-matched comparisons. A multilevel analysis indicated that BS-GPS was negatively associated with both LOS and LLOS after controlling for sociodemographics and the departments of patient discharge and remained negatively associated with LLOS after controlling additionally for the year of patient discharge. CONCLUSION Emotional distress significantly prolonged the LOS and increased the LLOS of non-psychiatric inpatients across most departments and general hospitals. These impacts were moderated by the implementation of BS-GPS. Thus, BS-GPS has the potential as an effective, resource-saving strategy for enhancing mental health care and optimizing medical resources in general hospitals.

Objective To investigate the health status of workers exposed to noise in a brewery in Beijing and to analyze the relationship between hearing loss and blood pressure. Methods A total of 949 noise-exposed workers in a brewery who participated in occupational health examination were selected as the investigation subjects. A survey was conducted to investigate the pure tone hearing threshold and abnormal blood pressure of the workers with different characteristics, and to analyze the relationship between the two. Results Among the noise-exposed workers, the detection rates of hearing abnormality, hypertension, and increased systolic and diastolic blood pressure were 73.55%, 52.37%, 43.84% and 46.47%, respectively. The detection rates of hearing abnormality, indicators of hypertension, high frequency hearing threshold abnormality and increased binaural high frequency hearing threshold on average in males were higher than those in females (P < 0.05). Except that there was no statistically significant difference in weighted values of the better ear’s hearing thresholds among different working age groups (P> 0.05), the detection rates of other hearing abnormality, indicators of hypertension, speech frequency hearing threshold abnormality, high frequency hearing threshold abnormality，increased binaural high frequency hearing threshold on average and the weighted value of the better ear's hearing threshold all increased or had an increasing trend with the increase of age or working years (P< 0.05). The detection rates of hypertension in the groups with high frequency hearing threshold abnormality and increased binaural high frequency hearing threshold on average were higher than those in the normal group (P＜0.05). Conclusion The noise-exposed workers in the brewery have hearing impairment, which is related to the occurrence of hypertension. It is recommended to strengthen the publicity and education on noise protection and take protective measures to reduce the occurrence of occupational noise injury.

Alzheimer's disease (AD) is a leading cause of dementia in the elderly. Mitogen-activated protein kinase phosphatase 1 (MKP-1) plays a neuroprotective role in AD. However, the molecular mechanisms underlying the effects of MKP-1 on AD have not been extensively studied. MicroRNAs (miRNAs) regulate gene expression at the post-transcriptional level, thereby repressing mRNA translation. Here, we reported that the microRNA-429-3p (miR-429-3p) was significantly increased in the brain of APP23/PS45 AD model mice and N2A^APP AD model cells. We further found that miR-429-3p could downregulate MKP-1 expression by directly binding to its 3'-untranslated region (3' UTR). Inhibition of miR-429-3p by its antagomir (A-miR-429) restored the expression of MKP-1 to a control level and consequently reduced the amyloidogenic processing of APP and Aβ accumulation. More importantly, intranasal administration of A-miR-429 successfully ameliorated the deficits of hippocampal CA1 long-term potentiation and spatial learning and memory in AD model mice by suppressing extracellular signal-regulated kinase (ERK1/2)-mediated GluA1 hyperphosphorylation at Ser831 site, thereby increasing the surface expression of GluA1-containing α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors (AMPARs). Together, these results demonstrate that inhibiting miR-429-3p to upregulate MKP-1 effectively improves cognitive and synaptic functions in AD model mice, suggesting that miR-429/MKP-1 pathway may be a novel therapeutic target for AD treatment.

Objective To estimate the disease burden of silicosis in China from 1990 to 2021 and analyze its changing trend using the data from the Global Burden of Disease Study 2021 (GBD 2021), and to provide evidence for the prevention and control of silicosis. Methods Data on the incidence, prevalence, morbidity and death, mortality and disability-adjusted life year (DALY) of silicosis in China were extracted from the GBD 2021 to analyze the disease burden and age distribution of silicosis. The average annual percentage change (AAPC) was calculated to reflect the temporal trend of various disease burden indicators from 1990 to 2021. The results were then compared with those of the global population. Results In China, prevalent cases of silicosis increased by 116.62% from 79 075 in 1990 to 171 291 in 2021; incident cases of silicosis increased by 75.75% from 13 315 in 1990 to 23 401 in 2021; deaths of silicosis increased by 30.76% from 4 837 in 1990 to 6 326 in 2021; DALYs of silicosis increased by 14.84% from 150,729.65 person-years in 1990 to 173 091.06 person-years in 2021. The age-standardized rate of prevalence, incidence, mortality, DALY, YLL, and YLD of silicosis in China all showed a downward trend. The AAPC (95% CI) was -0.42% (-0.56% ~ -0.29%), -1.02% (-1.16 %~ -0.88%), -2.16% (-2.49% ~ -1.83%), -2.24% (-2.63% ~ -1.84%), -2.45% (-2.76% ~ -2.14%), and -0.42% (-0.54% ~ -0.29%), respectively. From 1990 to 2021, the age-standardized indicators of silicosis in China were all higher than the global level, and the differences were statistically significant (all P <0.05). The proportion of silicosis incident cases in the total incident cases of pneumoconiosis in China increased from 68.49% in 1990 to 78.58% in 2021. Conclusion The age-standardized indicators of silicosis in China showed a downward trend from 1990 to 2021, but the number of prevalent cases, incident cases, and DALYs showed an increasing trend. The age-standardized incident rate of silicosis in China remains at a high level, suggesting that further efforts should be made to prevent and control silicosis.

Objective To evaluate the relationship between ceftazidime-avibactam(CAZ-AVI)blood concentrations and efficacy in critically ill patients and to investigate the factors influencing blood levels.Methods The CAZ-AVI trough concentrations(Cmin)were detected in 29 patients who received CAZ-AVI treatment for at least 48 hours.The clinical materials of the patients were collected together for retrospective analysis.Results The Cmin of ceftazidime(CAZ)and avibactam(AVI)were(50.95±5.17)and(7.52±0.96)mg·L-1 in the effective group and(31.16±7.03)and(5.37±1.32)mg·L-1 in the ineffective group,respectively.The Cmin of CAZ in the effective group was significantly higher than in the ineffective group(P<0.05),and there was no significant difference in AVI Cmin between the two groups(P>0.05).Spearman's correlation analysis showed that CAZ Cmin was positively correlated with clinical efficacy(P<0.05),and no correlation between AVI Cmin and clinical efficacy(P>0.05).The optimal CAZ Cmin threshold was 24.59 mg·L-1.Multiple linear regression analysis showed that age and creatinine clearance was significantly correlated with the Cmin of CAZ,and creatinine clearance was significantly correlated with AVI Cmin(P<0.05).Conclusions The Cmin of CAZ correlates with efficacy,and it may be more beneficial for clinical treatment to keep the concentration of CAZ-AVI always greater than the minimum inhibitory concentration during the dosing interval.The creatinine clearance should be fully considered when optimizing CAZ-AVI dosage in critically ill patients.

Polymyxins are the first-line drugs used in multidrug resistance(MDR)Gram-negative infections.Polymyxin-induced nephrotoxicity is the major dose-limiting factor hindering its clinical use.It has been suggested that the mechanism of polymyxin-associated nephrotoxicity is related to its accumulation in the kidney upon extensive reabsorption from renal proximal tubular cells,and one or more renal transporters may mediate the process that polymyxins enter the renal tubular cells across cytomembrane.This review aimed to describe the roles of renal transporters in polymyxins reabsorption into the renal tubular cells and provide reference for reducing the nephrotoxicity of polymyxin.

The symptoms of pulmonary nodules are insidious,with inflammatory nodules,inflammatory granuloma,early invasive cancer and lung cancer,and the clinical differential diagnosis is still difficult.Regular CT follow-up observation of most pulmonary nodules provides a"window period"for TCM Intervention in pulmonary nodules.From the aspects of external cold attacking the lung,dense cold and humid geographical environment,cold diet,summer air conditioning,etc.,this paper considers that the soaking of cold pathogenic factors is the basic cause of the formation of pulmonary nodules,and cold phlegm are the basic pathogenesis of pulmonary nodules.The clinical manifestations of cold phlegm in pulmonary nodules are summarized from the two actual situations that can be distinguished from clinical symptoms and no symptoms.It is proposed that Mahuang Fuzi Xixin Decoction and Sanzi Yangqin decoction are the basic formulas,Discussion on the treatment of pulmonary nodules by warming yang and dispelling cold to cure the root cause,eliminating phlegm and softening hard mass to treat the symptoms;Improve the ability of TCM diagnosis and treatment of pulmonary nodules.

Objective:To systematically review the profile of lymph node dissection (LND) for patients with intrahepatic cholangiocarcinoma (ICC) in China.Methods:Using the key words "intrahepatic cholangiocarcinoma" "intrahepatic cholangiocellular carcinoma" "lymph node dissection" "lymphadenec-tomy" "lymph node metastasis", the databases including China Zhiwang, Wanfang, Weipu, Sinomed, PubMed, Embase, Web of Science, Scopus, Cochrane Library were systematically searched. Cohort studies or randomized controlled clinical trials with intraoperative LND documentation and with analysis on the clinicopathologic characteristics or prognostic influences on patients with ICC were included into this meta-analysis from the date of database creation to April 20, 2022. The risk of bias in non-randomized controlled trials was evaluated using the Newcastle-Ottawa scale. A meta-analysis of preoperative imaging lymph node enlargement rates, LND rates, and pathological lymph node metastasis rates were performed using R software.Results:Thirty-three relevant studies that met the systematic evaluation criteria were included, all of which were retrospective cohort studies. All these publications were of medium to high quality. Patients’ enrollment ranged from 1993 to 2020. Patients were enrolled from 20 provinces/autonomous regions/municipalities with a total of 39 medical centers and 4 278 patients. The meta-analysis indicated that the LND rate, preoperative imaging lymph node enlargement rate, pathological lymph node metastasis rate were 47.8%(95% CI: 41.3%-54.3%), 18.5%(95% CI: 7.5%-29.6%) and 51.2%(95% CI: 43.8%-58.6%), respectively. Subgroup analysis showed the LND rate was 36.0%(95% CI: 27.0%-45.0%) in studies with a median year of enrollment before 2010, 48.3% (95% CI: 38.1%-58.6%) in studies from 2010 to 2017, and 53.3%(95% CI: 43.3%-63.2%) in studies after 2017. The LND rates were statistically different in the studies in the different periods of patient enrollment ( P=0.032). Conclusion:The meta-analysis indicated that the overall LND rate for ICC in China was not high but showed an increasing tendency.

Objective:To evaluate the effect of surgery under propofol anesthesia during mid-pregnancy on the cognitive function and hippocampal histone deacetylase 2 (HDAC2)-cAMP response element-binding protein (CREB)-N-methyl-D-aspartate (NMDA) receptor 2B subunit (NR2B)-containing NMDA receptor (NR2B) signaling pathway in the offspring rats.Methods:Thirty healthy Sprague-Dawley rats at 14 days of gestation were divided into 3 groups ( n=10 each) using a random number table method: propofol anesthesia group (P group), surgery under propofol anesthesia group (S group) and control group (C group). In S group, propofol 20 mg/kg was injected via the caudal vein, and then propofol was continuously infused at a rate of 20 mg·kg -1·h -1 to maintain anesthesia for 4 h, and exploratory laparotomy was performed. Group P received no exploratory laparotomy and the other treatments were similar to those previously described in group S. The equal volume of normal saline was given instead in group C. The learning and memory of the offspring rats was assessed using Morris water maze test on postnatal day 30. The expression of HDAC2, phosphorylated CREB (p-CREB), NR2B, brain-derived neurotriphic factor (BDNF) and phosphorylated tyrosine kinase B (p-TrkB) in offspring′s hippocampi was evaluated by Western blot. Apoptosis in hippocampal neurons was detected by TUNEL staining. Results:Compared with group C, the escape latency was significantly prolonged, the frequency of crossing the original platform was decreased, the time spent in the second quadrant was shortened, the expression of HDAC2 was up-regulated, the expression of p-CREB, NR2B, BDNF and p-TrkB was down-regulated, and the apoptosis rate of the hippocampal neurons was increased in P and S groups ( P<0.05). Compared with P group, the escape latency was significantly prolonged, the frequency of crossing the original platform was decreased, the time spent in the second quadrant was shortened, the expression of HDAC2 was up-regulated, the expression of p-CREB, NR2B, BDNF and p-TrkB was down-regulated, and the apoptosis rate of the hippocampal neurons was increased in S group ( P<0.05). Conclusions:Surgery under propofol anesthesia during mid-pregnancy can decrease the cognitive function of offspring rats, and the mechanism is related to the regulation of HDAC2-CREB-NR2B signaling pathway and the promotion of apoptosis in hippocampal neurons.
