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.

BACKGROUND: As the efficacy of programmed cell death-1/programmed death-ligand 1 (PD-1/PD-L1) inhibitors combined with chemotherapy in curing breast cancer is still controversial, this meta-analysis compares the efficacy and safety of PD-1/PD-L1 inhibitors combined with chemotherapy and chemotherapy alone in the treatment of breast cancer, which provides guidance for the clinical treatment. METHODS: Relevant studies published as of April 2022 in the various databases including EMBASE, PubMed, and Cochrane Library were selected. Randomized controlled trials (RCTs) in which control patients underwent chemotherapy alone and experimental group patients underwent combination chemotherapy and PD-1/PD-L1 inhibitor treatment were included in this investigation. Investigations without complete information, researches from which information could not be extracted, duplicate articles, animal studies, review articles, and systematic reviews were excluded. STATA 15.1 was employed for all statistical analyses. RESULTS: In total, eight eligible studies were identified, revealing that combination chemotherapy and PD-1/PD-L1 inhibitor treatment was linked to significant increases in progression-free survival (PFS) relative to chemotherapy alone (hazard ratio [HR] = 0.83, 95% confidence interval [CI]: 0.70-0.99, P = 0.032) but not overall survival (HR = 0.92, 95% CI: 0.80-1.06, P = 0.273). Pooled adverse event rates were also increased within the group of combination treatment relative to the chemotherapy group (risk ratio [RR] = 1.08, 95% CI: 1.03-1.14, P = 0.002). Specifically, nausea rates were lesser within the group of combination treatment relative to the group of chemotherapy (RR = 0.48, 95% CI: 0.25-0.92, P = 0.026). Subgroup analyses indicated that the PFS of patients who underwent combination atezolizumab or pembrolizumab and chemotherapy treatment were substantially longer than those of patients who underwent chemotherapy alone (HR = 0.79, 95% CI: 0.69-0.89, P ≤0.001; HR = 0.79, 95% CI: 0.67-0.92, P = 0.002). CONCLUSIONS The pooled results suggest that combination chemotherapy and PD-1/PD-L1 inhibitor treatment approaches help prolong PFS in breast cancer patients, but have no statistically significant effect on overall survival (OS). Additionally, combination therapy can significantly improve complete response rate (CRR) compared with chemotherapy alone. However, combination therapy was associated with greater rates of adverse events.

Objective To establish a high performance liquid chromatography (HPLC) method for simultaneous determination of six aniline compounds (ADs) in workplace air. Methods GDH-1 air sampling tube was used to collect six co-existing ADs such as aniline, o-toluidine, N-methylaniline, m-methylaniline, p-methylaniline and N,N-dimethylaniline in the vapor and aerosol of workplace air. The samples were desorbed and eluted using a methanol solution containing 1.00% ammonia water, followed by separation on a C₁₈ chromatographic column and detection using a diode array detector. Results The quantification range of the method was 0.19 -253.50 mg/L, with the correlation coefficient of 0.999 9 for all six ADs. The minimum detection range was 0.02-0.06 mg/m³, and the minimum quantitation range was 0.04-0.19 mg/m³ [both calculated for a 15.0 L sample with a desorption (elution) solution volume of 3.00 mL]. The average desorption and elution efficiencies were 92.15%-104.41% (silica gel) and 94.29%-104.29% (filter membrane). The intra-assay relative standard deviation (RSD) ranged from 0.90%-9.72% (silica gel) and 0.57%-6.96% (filter membrane). The inter-assay RSD ranged from 2.03%-9.78% (silica gel) and 2.50%-8.62% (filter membrane). The samples were stable at room temperature for seven days. Conclusion This method can be used for the simultaneous determination of six ADs in workplace air.

Objective:To evaluate the clinical efficacy and safety of retrograde intrarenal surgery(RIRS) and miniaturized percutaneous nephrolithotomy(mini-PCNL) in the treatment of lower pole kidney stones with a diameter <1.5 cm.Methods:The data of 95 patients with lower pole kidney stones with a diameter <1.5 cm treated in Renmin Hospital of Wuhan University from June 2017 to October 2020 were retrospectively analyzed. According to different surgical methods, the patients were divided into RIRS group and mini-PCNL group. There were 51 cases in RIRS group and 44 cases in mini-PCNL group. There was no significant difference in age [(48.2±11.4) years vs. (46.4±14.1) years], body mass index [(21.9±2.4) kg/m 2 vs. (20.7±3.2) kg/m 2], gender [male/female: 37/14 vs. 24/20], stone CT [(746.42±164.24)HU vs. (858.62±148.72)HU], creatinine [(71.3±21.6)μmol/L vs. (63.5±20.3)μmol/L], stone location (left/right: 26/25 vs. 23/21), stone diameter [(10.5±2.1) mm vs. (12.5±2.4) mm], infundibulopelvic angle [(43.32±9.42) degrees vs. (43.82±10.34) degrees], infundibular length [(24.92±4.85)mm vs. (24.37±5.26)mm] and infundibular [(9.26±3.04)mm vs.(9.46±2.94)mm] between the two groups ( P>0.05). The operation time, stone-free rate, hospital stay and postoperative complications between the two groups were compared. Results:Compared with the mini-PCNL group, the RIRS group had significantly smaller decrease in postoperative hemoglobin [(1.53±0.92) g/L vs. (4.54±2.46) g/L, P<0.05], the postoperative hospital stay was shorter [(2.52±0.94) d vs. (4.51±1.25)d, P<0.05], and postoperative visual analogue score was lower [(2.43±0.92) vs. (3.24±0.76), P<0.05]. The operation time of the mini-PCNL group was shorter than that of the RIRS group [(42.32±13.28) min vs. (54.24±14.43)min, P<0.05]. There was no significant difference in postoperative complications [5.9% (3/51) vs. 11.4% (5/44), P>0.05], postoperative cveatinine [(71.3±21.6) μmol/L vs. (63.5±20.3) μmol/L, P>0.05], postoperative intestinal function recovery time [(25.46±10.28)h vs. (32.43±9.25)h, P>0.05] and stone-free rate [92.2% (47/51) vs. 97.7% (43/ 44), P>0.05] between the two groups. Conclusions:Both RIRS and mini-PCNL are effective and safe minimally invasive treatments for lower pole kidney stones with a diameter < 1.5 cm. RIRS has shorter operation time, less blood loss, lower pain score and faster postoperative recovery.

The Brodmann area(BA)-based map is one of the most widely used cortical maps for studies of human brain functions and in clinical practice;however,the molecular architecture of BAs remains unknown.The present study provided a global multiregional proteomic map of the human cerebral cortex by analyzing 29 BAs.These 29 BAs were grouped into 6 clusters based on similarities in proteomic patterns:the motor and sensory cluster,vision cluster,auditory and Broca's area cluster,Wernicke's area cluster,cingulate cortex cluster,and heterogeneous function cluster.We identified 474 cluster-specific and 134 BA-specific signature proteins whose functions are closely associated with specialized functions and disease vulnerability of the corresponding clus-ter or BA.The findings of the present study could provide explanations for the functional connec-tions between the anterior cingulate cortex and sensorimotor cortex and for anxiety-related function in the sensorimotor cortex.The brain transcriptome and proteome comparison indicates that they both could reflect the function of cerebral cortex,but show different characteristics.These pro-teomic data are publicly available at the Human Brain Proteome Atlas(www.brain-omics.com).Our results may enhance our understanding of the molecular basis of brain functions and provide an important resource to support human brain research.

Objective::This study was to supply information of the Duchenne muscular dystrophy (DMD) mutational spectrum in 303 Chinese families and further offer 5-year clinical experience of DMD/Becker muscular dystrophy genetic counseling and prenatal diagnosis.Methods::In this retrospective cohort study, three hundred and five pregnancies in 303 pregnant women who has a birth history of DMD/Becker muscular dystrophy patients underwent prenatal diagnosis using multiplex ligation-dependent probe amplification followed by Sanger sequencing between January 2014 and December 2018 at Peking Union Medical College Hospital. The mean age of pregnant women was (33.0 ± 4.1) years old. Karyotype analysis was performed to exclude fetal abnormal karyotype.Results::The detection rate of DMD gene mutation in 303 probands was (296/303) 97.7% with seven families having a negative genetic diagnosis. The mutational spectrum comprised of large arrangements in 288/303 (95.0%) and small mutations in 8/303 (2.6%). Carrier testing was performed among 204 pregnant women among whom, 108 mothers had the same mutation as family proband. Of the 305 pregnancies underwent prenatal diagnosis, 55 of 173 male fetuses were affected. We also performed karyotype analysis and found three abnormal karyotypes of trisomy 21. We even found a fetus with DMD gene mutation and trisomy 21 in a same fetus by further analysis. We also identified two times of germline mosaicism. Conclusion::This study demonstrated the distribution and mutation profile of 303 probands and 305 fetuses. Furthermore, considering the possbility of maternl germilne mosaicism, prenatal diagnosis should be suggested to mothers with a proband whether they carry the causative mutation in their blood or not.

Objective Establishment of an osimertinib-resistant PC-9/ZDOR cell line of human non-small cell lung cancer (NSCLC) , and exploration of its drug resistance mechanisms and the sensitivity of themotherapeutic drugs. Methods An osimertinib-resistant PC-9/ZDOR cell line was induced by increasing doses of osimertinib to gefitinib-resistant cells PC-9/ZD. Mutation analysis of EGFR genes was performed by NGS. Cell growth was measured by CCK-8 assay and the sensitivity of chemotherapy was determined via analysis of resistance index (RI).The expression of EGFR and its signal transduction protein was determined by western blot. Results (1) An osimertinib-resistant human NSCLC cell line PC-9/ZDOR was successfully established with resistance index of 44. (2) The evidence from NGS data showed the mutation and amplification of EGFR was eliminated in PC-9/ZDOR cells. (3) The data from Western blot showed that the expression of EGFR and its phosphorylated form protein such as P-AKT and P-ERK was significantly decreased in PC-9/ZDOR cells when compared with those in PC-9/ZD cells (P <0.05). (4) The sensitivity of PC-9/ZDOR cell lines to docetaxel, gemcitabine and paclitaxel was significantly higher than that of PC-9/ZD cell lines (P < 0.05) , while the sensitivity of PC-9/ZDOR cell lines to cisplatin and pemetrexed was similar to the one of PC-9/ZD cell lines (P> 0.05). Conclusions The PC-9/ZDOR cell lines is an osimertinibresistant human NSCLC cell line. Elimination of EGFR gene mutation and/or the decrease of protein expressions of EGFR, p-EGFR, p-ERK and p-AKT maybe serve as the mechanisms of acquired resistance to osimertinib. This osimertinib-resistant cell line, PC-9/ZDOR, showed a elevated level of sensitivity to taxanes and gemcitabine.

Objective : To investigate the influencing factors for depression and anxiety in patients with dysphagia after stroke. Methods: From May 2017 to June 2018,patients with post-stroke dysphagia in the Department of Rehabilitation Medicine of Zhejiang Hospital were recruited to collect their height,weight,education level,serum nutritional indicators and feeding patterns. Self-Rating Anxiety Scale and Self-Rating Depression Scale were employed to assess the incidence of anxiety and depression. Multivariate logistic regression model was used to analyze the influencing factors for depression and anxiety. Results : Among 96 patients enrolled,43 suffered from anxiety and depression,with the incidence of 44.79%. The results of multivariate logistic regression analysis showed that normal albumin（OR=0.208,95%CI：0.054-0.800）was a protective factor for anxiety,while indwelling gastric tube（OR=5.789,95%CI：1.654-20.260）was a risk factor. Normal transferrin（OR=0.189,95%CI：0.042-0.860）was a protective factor for depression,while indwelling gastric tube（OR=13.977,95%CI：1.472-132.667）was a risk factor. Conclusion Normal albumin and transferrin are the protective factors for anxiety and depression in patients with dysphagia after stroke,and indwelling gastric tube is the risk factor for anxiety or depression.
