Objective To explore the relationship and internal path between activities of daily living(ADL),sleep quality and mental health of community elderly people in Shanghai.Methods A questionnaire survey was conducted among community residents aged 60 years and older seeing doctors in community health care center of five streets in Shanghai during Sept to Dec,2021 using convenience sampling.Activities of Daily Living(ADL),Pittsburgh Sleep Quality Index(PSQI)and 10-item Kessler Psychological Distress Scale(K10)were adopted in the survey.Single factor analysis,correlation analysis and multiple linear regression were used to analyze the data.The effect relationship between the variables was tested using Bootstrap's mediated effects test.Results A total of 1 864 participants were included in the study.The average score was 15.53±4.47 for ADL,5.60±3.71 for PSQI and 15.50±6.28 for K10.The rate of ADL impairment,poor sleep quality,poor and very poor mental health of the elderly were 23.6%,27.3%,11.9%and 4.9%,respectively.ADL and sleep quality were all positively correlated with mental health(r=0.321,P＜0.001;r=0.466,P＜0.001);ADL was positively correlated with sleep quality(r=0.294,P＜0.001).Multiple linear results of factors influencing mental health showed that ADL(β= 0.457,95%CI:0.341-0.573),sleep quality(β =0.667,95%CI:0.598-0.737)and mental health were positively correlated(P＜0.001).Sleep quality partially mediated the relationship between ADL and mental health(95%CI:0.078-0.124)with an effect size of 33.0%.Conclusion Sleep quality is a mediator between ADL and mental health among community elderly people.Improving ADL and sleep quality may improve mental health in the population.

AIM: Yi Qi Yang Yin Decoction (YQYY) has been used to treat patients with rheumatoid arthritis (RA) and achieved good results in clinical applications, but the mechanism still needs to be explored. The purpose was to investigate the mechanism of YQYY in rats with collagen-induced arthritis. METHODS: The possible treatment target and signaling pathway were predicted by bioinformatics and network pharmacology analysis. Elisa,quantitative real-time polymerase chain reaction, and Western Blot were used to verify the mechanism of YQYY in treating RA. RESULTS: FABP4, MMP9 and PTGS2 were the most common predicational therapeutic targets. The results of pathology and CT showed that YQYY could improve ankle swelling, synovitis and bone erosion in CIA rats. Compared with the model group, YQYY or YQYY+MTX can significantly reduce the secretion of CRP, TNF-α, IL-1β and FABP4 in serum of CIA rats (P<0.05 or P<0.01), meanwhile, reduce the mRNA of FABP4, IKKα and p65 in synovial tissue (P<0.01), PPARγ was increased (P<0.01). YQYY could significantly reduce the expression of FABP4, IKKα and pp65 proteins in synovium, and suppress the activate of NF - κB signaling pathway. CONCLUSION: FABP4, MMP9 and PTGS2 may be the targets of YQYY decoction for RA treatment. YQYY can relieve joint symptoms in CIA rats, and regulate inflammation by inhibiting FABP4 / PPARγ/NF - κB signaling pathway, playing a role in the treatment of RA. The effect of YQYY combined with MTX was more prominent. This provided experimental evidence for the efficacy of YQYY decoction in clinical practice.

Objective:To analyze the variations of serum lymphocyte subsets, immunoglobulins, and complement levels in patients with cheilitis, and to explore the associations between the changes in serum immune levels and the onset of cheilitis.Methods:A retrospective analysis was conducted on 153 patients with cheilitis who visited the Department of Stomatology, The First Affiliated Hospital of Zhengzhou University from January 2017 to December 2023. They were compared with 50 healthy individuals who visited the physical examination department during the same period. The changes of serum lymphocyte subsets, immunoglobulins, and complement levels in patients with cheilitis were analyzed. Main detection indicators as the percentage of total T lymphocytes (T%), helper/inducer T lymphocytes (CD4 +T%), absolute numbers of total T lymphocytes (T#), absolute numbers of helper/inducer T lymphocytes (CD4 +T#), percentage of natural killer cells (NK%), absolute numbers of B lymphocytes (B#), immunoglobulins IgG, IgM and complement C3, C4 were included. Multivariate logistic regression was used to explore the relationship between serum lymphocyte subsets, immunoglobulins, complement levels and cheilitis. Subgroup analysis was further conducted on patients with cheilitis based on gender, age, cheilitis type and severity. Results:The levels of T% [69.54% (64.41%, 75.14%)], CD4 +T% [(35.09±7.10)%], T# [1 328.00 (1 054.00, 1 560.50)], and CD4 +T# [653.00 (505.00, 831.50)] in the cheilitis group were significantly lower than those in the control group respectively [72.33% (69.41%, 75.47%), (39.07±5.84)%, 1 483.50 (1 245.75, 1 805.25), 769.00 (687.25, 933.00), with the corresponding statistical test results of Z=-2.64, P=0.008; t=3.58, P<0.001; Z=-2.80, P=0.005; Z=-3.80, P<0.001]. The level of NK% [16.21% (12.16%, 21.29%)] was significantly higher in the cheilitis group compared to the control group [14.61% (10.97%, 17.87%)] ( Z=-2.28, P=0.023). IgG [12.29 (10.77, 13.73) g/L] and IgM levels [1.18 (0.86, 1.58) g/L] were significantly higher in the cheilitis group than in the control group respectively [11.52 (10.16, 12.91) g/L, 0.99 (0.77, 1.26) g/L] ( Z=-2.24, P=0.025; Z=-2.10, P=0.036), while complement C3 [(1.09±0.17) g/L] and C4 levels [0.23 (0.19, 0.28) g/L] were significantly lower in the cheilitis group compared to the control [(1.18±0.17) g/L, 0.31(0.24, 0.35) g/L] ( t=3.10, P=0.002; Z=-4.79, P<0.001). Logistic regression analysis showed that elevated IgG ( P=0.021), decreased C4 ( P<0.001), decreased CD4 +T% ( P=0.003), and decreased T# ( P=0.035) were independent influencing factors for the occurrence of cheilitis. The rate of abnormal lymphocyte immune analysis in the cheilitis group [68.0% (104/153)] was significantly higher than that in the control group [24.0% (12/50)] (χ 2=29.76, P<0.001). The rate of abnormal immunoglobulin and complement detection in the cheilitis group [41.8% (64/153)] was significantly higher than that in the control group [4.0% (2/50)] (χ 2=24.58, P<0.001). The rate of detection abnormalities in female patients with cheilitis [51.5% (53/103)] was significantly higher than in male ones [22.0% (11/50)] (χ 2=12.00, P=0.001). Patients with granulomatous cheilitis had significantly lower levels of T# [1 136.50 (663.75, 1 310.50)] and B# [162.50 (104.00, 225.50)] compared to those with chronic cheilitis [1 366.00 (1 063.03, 1 602.00), 202.48 (148.00, 298.00)] ( Z=-2.35, P=0.019; Z=-2.16, P=0.031). Conclusions:Patients with cheilitis exhibit a certain degree of imbalance on cellular immunity, humoral immunity, and innate immunity, which may be related to the onset of cheilitis.

Objective:To summarize the characteristics of color doppler flow imaging (CDFI) of ocular toxocariasis (OT) in children.Methods:A retrospective clinical study. From July 2014 to June 2020, 61 OT patients with 61 eyes diagnosed through clinical and laboratory testing in the Department of Ophthalmology of Beijing Tongren Hospital of Capital Medical University were included in the study. There were 45 males with 45 eyes and 16 females with 16 eye (male: female=2.81:1). Age were (6.93±2.50) years. The right eye and left eye were 29 and 32 eyes, respectively. Both eyes of the patient underwent two-dimensional ultrasound and CDFI examination. Two dimensional ultrasound was used to estimate the axial length (AL) of the affected eyes and healthy eyes on the opposite side. Among them, 52 cases were measured for AL using optical biometry and/or A-mode ultrasound. Vitreoretinal surgery was performed within one week after ultrasound examination. Two-dimensional ultrasound was used to observe the morphology of vitreous opacity, its connection to the eyeball wall, and whether posterior vitreous detachment and retinal detachment have occurred. CDFI examination was used to observe the presence of blood flow signals on the pathological membrane. The detection rates of different forms of vitreous opacity and traction retinal detachment were calculated. The location of proliferative lesions in the eye was analyzed. Paired t-test was performed to compare the AL of the affected eye and the healthy eye on the opposite side. Perform Kappa consistency test on the location of proliferative lesions was used during CDFI examination and vitreoretinal surgery. Results:All affected eyes have varying degrees of vitreous opacity. Among them, 23 eyes (37.7%, 23/61) showed typical "Christmas tree" like turbidity; 27 eyes (44.3%, 27/61) had clustered and striped echoes; 9 eyes (14.8%, 9/61) had weak punctate and strip echoes. Two eyes (3.3%, 2/61) showed a large amount of dense punctate and strip-shaped echoes. There were 50 eyes (82.0%, 50/61) with traction retinal detachment, of which 46 eyes (92.0%, 46/50) had visible blood flow signals on the detached retina, and the remaining 4 eyes (8.0%, 4/50) had no blood flow signals. During CDFI and surgery, there were 5 (8.2%, 5/61) and 4 (6.6%, 4/61) eyes with visible proliferative lesions in the periphery, respectively; 18 (29.5%, 18/61) and 14 (23.0%, 14/61) eyes were distributed in the posterior pole, respectively; there were 38 (62.3%, 38/61) and 43 (70.5%, 43/61) eyes with both peripheral and posterior polar regions, respectively. The consistency between CDFI and surgery in detecting the location of proliferative lesions was good ( κ=0.832, 95% confidence interval 0.691-0.973, P<0.001). The two-dimensional ultrasound measurement results showed that the AL of the affected eye was shorter than that of the contralateral healthy eye in 46 cases (75.4%, 46/61). Among the 52 patients who underwent AL biometry, the AL of the affected eye was shorter than that of the contralateral healthy eye by (0.63±0.68) mm, and the difference was statistically significant ( t=-6.738, P<0.05). Conclusions:CDFI can clearly display various intraocular lesions (vitreous opacity and traction retinal detachment) and eyeball sizes in children with OT. Vitreous opacity is often manifested as "Christmas tree" like, clustered, strip-shaped.

We aimed to identify the infectious source of a case of melioidosis,to provide evidence for the prevention and control of melioidosis in Shanxi Province,China.The patient developed repeated fever,fatigue,diarrhea,and other symptoms after being caught in the rain while traveling in Hainan Province.The blood culture was positive,and the bacterial strain was i-dentified as Burkholderia thayensis and sent to the provincial Center for Disease Control and Prevention for further evaluation.MALDI-TOF MS and biochemical identification were used to identify the strain,whole genome sequencing was performed after nucleic acid extraction,MLST type and drug-resistance genes were analyzed,and a phylogenetic tree was constructed.The iso-lated strain was identified as Burkholderia pseudomallei by MALDI-TOF MS and biochemistry,and the MLST type was 366.The whole gene sequencing analysis indicated a close evolutionary relationship with the three isolates in Hainan Province,with high homology.This case of melioidosis was indeed imported from Hainan Province,according to molecular tracing analysis and epidemiological investigation,thus suggesting that medical institutions and disease control departments should strengthen understanding of melioidosis,and improve the diagnosis and treatment ability.

Objective To investigate the epidemiological characteristics and mutation spectrum of monogenic diseases in Chinese population through a large-scale,multicenter carrier screening.Methods This study was conducted among a total of 33 104 participants(16 610 females)from 12 clinical centers across China.Carrier status for 223 genes was analyzed using high-throughput sequencing and different PCR methods.Results The overall combined carrier frequency was 55.58%for 197 autosomal genes and 1.84%for 26 X-linked genes in these participants.Among the 16 669 families,874 at-risk couples(5.24%)were identified.Specifically,584 couples(3.50%)were at risk for autosomal genes,306(1.84%)for X-linked genes,and 16 for both autosomal and X-linked genes.The most frequently detected autosomal at-risk genes included GJB2(autosomal recessive deafness type 1A,393 couples),HBA1/HBA2(α-thalassemia,36 couples),PAH(phenylketonuria,14 couples),and SMN1(spinal muscular atrophy,14 couples).The most frequently detected X-linked at-risk genes were G6PD(G6PD deficiency,236 couples),DMD(Duchenne muscular dystrophy,23 couples),and FMR1(fragile X syndrome,17 couples).After excluding GJB2 c.109G>A,the detection rate of at-risk couples was 3.91%(651/16 669),which was lowered to 1.72%(287/16 669)after further excluding G6PD.The theoretical incidence rate of severe monogenic birth defects was approximately 4.35‰(72.5/16 669).Screening for a battery of the top 22 most frequent genes in the at-risk couples could detect over 95%of at-risk couples,while screening for the top 54 genes further increased the detection rate to over 99%.Conclusion This study reveals the carrier frequencies of 223 monogenic genetic disorders in the Chinese population and provides evidence for carrier screening strategy development and panel design tailored to the Chinese population.In carrier testing,genetic counseling for specific genes or gene variants can be challenging,and the couples need to be informed of these difficulties before testing and provided with options for not screening these genes or gene variants.

OBJECTIVE To clarify the weight index and optimize the technology of compound Mingmu Yijing pills. METHODS Water content, dissolution time limit and bolus-forming pass rate were included as evaluation indexes. The analytic hierarchy process(AHP) and the criterion importance through inter-criteria correlation(CRITIC) method based on the objectivity of indicators were adopted, AHP-CRITIC mixed weighting method. In this way, the relative coefficients of each index were calculated for weight distribution and comprehensive score, and the molding process was optimized and verified by Box-Behnken response surface test.

This method finally optimized the forming process conditions of Mingmu Yijing pills as follows: adding water amount of 0.8 times, the damp mass infiltration for 0.5 h, drying temperature of 60 ℃, drying time of 8 h. The mean comprehensive score of validation experiment was 88.21, RSD was 0.29%. CONCLUSION AHP-CRITIC method scientifically determines the weight of multiple indicators, and the verification test confirms that the optimized molding process is stable and feasible, which can be used in practical large-scale production.

Objective To investigate the current status of off-label drug use(OLDU)management in tertiary hospitals of Guizhou province and to provide baseline evidence for developing a unified administration regulation for OLDU in Guizhou province.Methods In line with the relevant policies and regulations,a questionnaire including basic information about the person filling out the form,basic information about the hospitals,and information about OLDU was developed.The questionnaire was sent to 84 tertiary hospitals in Guizhou province through the Wenjuanxing.Results A total of 84 questionnaires were distributed and recovered,with a response rate of 100.00%.Of the 84 hospitals,77 had OLDU,of which 68(88.31%)had established a management system for OLDU.Among the 77 hospitals with OLDU,65(84.42%),42(54.55%),58(75.32%),36(46.75%),15(19.48%),and 21(27.27%)hospitals respectively,required approval from the Committee on Drug Administration and Pharmacotherapy before OLDU,restricted the qualifications of doctors prescribing OLDU,required informed consent from patients or their families before OLDU,recorded the matters and reasons in the medical records of patients treated with OLDU,followed up patients in their files and evaluated the reasonableness of the OLDU,and carried out special reviews for OLDU.Only 30(38.96%)hospitals have set up a catalogue of OLDUs,and 58(75.32%)hospitals have urgent needs to set up a unified provincial catalogue of OLDUs.Conclusion The pharmacy administration level of OLDU in tertiary hospitals of Guizhou province is relatively low,so there is an urgent need to establish a unified OLDU management system and medication catalog.

As a potent narcotic opioid analgesic,fentanyl has been used as intravenous anesthesia for clinical procedures while also being abused by drug users,resulting in an increasing number of deaths year by year,and thus it is urgent to develop rapid screening methods for fentanyl.In this study,by using a binary metal-organic framework MIL-88B(Fe/Ni)as an electrocatalyst,an electrochemical sensor based on multi-walled carbon nanotubes(MWCNTs)modified glassy carbon electrode(GCE)was constructed for rapid detection of fentanyl.The morphology,crystal structure and elemental characteristics of the synthesized MIL-88B(Fe/Ni)/MWCNTs and MIL-88B(Fe/Ni)composites were confirmed by scanning electron microscopy(SEM),energy dispersive X-ray spectroscopy(EDS),X-ray diffraction(XRD)and X-ray photoelectron spectroscopy(XPS).In addition,the electrochemical characterization also revealed that the synthesized MIL-88B(Fe/Ni)/MWCNTs composites modified GCE possessed low electrochemical impedance and large electrochemical surface area with ultra-high sensitivity to fentanyl.The experimental conditions for the electrochemical detection of fentanyl were optimized and the limit of detection(LOD,3Sb/M)for fentanyl was 0.015 μmol/L with a linear range of 0.04-10 μmol/L,and the reproducibility,selectivity and stability were all favorable.In addition,the developed sensor showed satisfactory performance in real samples,with recoveries ranging from 58.6%to 81.5%and from 82.7%to 97.5%in urine and blood,respectively,at concentration levels of 0.2-1.0 μmol/L.The proposed MIL-88B(Fe/Ni)/MWCNTs composite could be used as a novel electrode material for electrochemical detection of fentanyl,and had great potential for rapid detection of fentanyl in public security anti-drug or medical emergency.
