OBJECTIVE To evaluate the efficacy and safety of intranasal corticosteroids （INCS） combined with oral H1- antihistamine （AH） in the treatment of allergic rhinitis. METHODS A comprehensive literature search was conducted in PubMed， Embase， CNKI， and VIP database to collect randomized controlled trial （RCT） that INCS combined with AH （experimental group） versus INCS （control group） in the treatment of allergic rhinitis from the inception to December 31， 2024. After study selection， data extraction， and quality assessment， a meta-analysis was performed by using RevMan 5.3 software. RESULTS A total of 12 RCTs were included in the meta-analysis， with a total of 1 842 patients. Results of meta-analysis showed that， compared with the control group， patients in the experimental group had a greater reduction in sneezing scores， rhinorrhea scores， nasal congestion scores， nasal itching scores， total nasal symptom scores， total ocular symptom scores， and rhinoconjunctivitis quality of life questionnaire scores （P＜0.05）. The incidence of headache was lower in the experimental group （P＜0.05）； whereas there were no significant differences between the two groups in the incidence of nosebleed， dryness of the mouth and nose， drowsiness， fatigue， and total adverse events （P＞0.05）. CONCLUSIONS Compared with INCS monotherapy， the combination of INCS and oral AH provides superior efficacy and safety in the treatment of allergic rhinitis.

ObjectiveTo investigate the change in the expression of magnesium transporter 1 （MagT1） in peripheral blood CD8⁺ T cells in patients with chronic hepatitis B virus （HBV） infection， as well as the correlation of serum Mg²⁺ and MagT1 with HBV DNA load. MethodsA total of 102 patients with HBV infection who were admitted to Tangshan Workers’ Hospital from January 2022 to December 2023 were enrolled， and a case-control study was conducted. According to the stage of disease progression， the subjects were divided into chronic hepatitis B group with 40 patients， compensated liver cirrhosis group with 32 patients， and hepatocellular carcinoma group with 30 patients， and 32 healthy volunteers matched by age and sex were enrolled as normal control group. The serum concentration of Mg²⁺ was measured； RT-qPCR was used to measure the mRNA expression level of MagT1 in CD8⁺ T cells and serum HBV DNA load； flow cytometry was used to measure the expression levels of programmed death-1 （PD-1）， T-cell immunoglobulin and mucin-domain containing-3 （Tim-3）， and natural killer cell group 2D （NKG2D） on the surface of CD8⁺ T cells. A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups， and the SNK-q test was used for comparison between two groups； the chi-square test was used for comparison of categorical data between groups； a Pearson linear correlation analysis was used to investigate the correlation between the mRNA expression level of MagT1 and other related indicators. ResultsThere were significant differences in the serum level of Mg²⁺ and the mRNA expression level of MagT1 between the normal control group， the chronic hepatitis B group， the compensated liver cirrhosis group， and the hepatocellular carcinoma group （F=29.014 and 145.578， both P<0.001）. The Pearson correlation analysis showed that the serum level of Mg²⁺ and the mRNA expression level of MagT1 were positively correlated with HBV DNA load （r=0.335 and 0.394， both P<0.05）. The hepatocellular carcinoma group had the highest levels of PD-1 and Tim-3， followed by the compensated liver cirrhosis group， the chronic hepatitis B group， and the normal control group； the normal control group had the highest level of NKG2D， followed by the chronic hepatitis B group， the compensated liver cirrhosis group， and the hepatocellular carcinoma group （all P<0.001）. The Pearson correlation analysis showed that the mRNA expression level of MagT1 was negatively correlated with PD-1 and Tim-3 （r=-0.643 and -0.640， both P<0.05） and was positively correlated with NKG2D （r=0.655， P<0.05）. ConclusionThere is a reduction in the mRNA expression level of MagT1 in peripheral blood CD8⁺ T cells in patients with HBV infection， which is positively correlated with serum HBV DNA load. The reduction in the expression of MagT1 may contribute to CD8⁺ T cell exhaustion by impairing Mg²⁺ influx， manifesting as the upregulation of PD-1 and Tim-3 and the downregulation of NKG2D.

Background As a key to economic and social development, occupational groups with low levels of occupational health literacy (OHL) are considered vulnerable groups with high risks of work-related diseases and injuries. Therefore, improving the OHL of these groups is of great significance in reducing the burden on public health. Objective To master the four dimensional OHL levels and influencing factors of the key groups in Fuling District, Chongqing, and provide a basis for formulating health education programs for occupational groups in the future. Methods The Occupational Health Literacy Questionnaire of Key Populations was distributed online to investigate the key occupational groups in Fuling District through stratified cluster sampling. The survey collected data on basic demographic information, legal knowledge of occupational health, basic knowledge of occupational health protection, basic skills of occupational health protection, and healthy working style and behavior. Univariate analysis, logistic regression, and nomogram were used to analyze the above data. Results This survey distributed 4824 questionnaires, of which 4677 were valid, with a recovery rate of 97.0%. The dimensional OHL levels of key occupational groups in Fuling District from high to low were: healthy working style and behavior (79.1%), basic knowledge of occupational health protection (78.4%), legal knowledge of occupational health protection (43.3%), and basic skills of occupational health protection (37.6%). The results of logistic regression showed that the occupational health legal knowledge levels in the groups of high school/vocational high school/technical secondary school and above (reference: primary school and below) (OR=1.47, 95%CI: 1.05, 2.05), ≥3000 yuan of monthly income (reference: <3000 yuan of monthly income) (OR=1.39, 95%CI: 1.06, 1.84), and medium enterprises (reference: micro enterprises) (OR=1.84, 95%CI: 1.29, 2.63) were higher; the occupational health legal knowledge level in the electricity, heat, gas, and water production and supply industry was lower than that in the mining industry (OR=0.68, 95%CI: 0.47, 0.97); the basic knowledge levels of occupational health protection in the groups of ≥ 3 years of service (reference: < 3 years of service) (OR=0.78, 95%CI: 0.65, 0.94) and medium enterprises (reference: large enterprises) (OR=0.78, 95%CI: 0.64, 0.95) were lower; the basic knowledge level of occupational health protection in the ethnic minorities was higher than that in the Han ethnic group (OR=1.73, 95%CI: 1.04, 2.87); the occupational health protection basic skill level in the group of ≥ 3 years of service (reference: < 3 years of service) (OR=0.69, 95%CI: 0.60, 0.79) was higher; the level of healthy working style and behavior in the group of ≥ 11 years of service (reference: < 3 years of service) (OR=0.73, 95%CI: 0.59, 0.89) was lower; the level of healthy working style and behavior in the group of high school/vocational high school/technical secondary school and above (reference: primary school and below) (OR=1.60, 95%CI: 1.15, 2.23) was higher. The nomogram showed that educational level and monthly income had the greatest impact on the occupational health legal knowledge level; length of service had the greatest impact on the basic knowledge of occupational health protection level and the healthy working style and behavior level. Conclusion In the future, the focus of health education and health promotion in Fuling District should be implemented to improve the basic skills of occupational health protection and the legal knowledge of occupational health, especially for workers with low education, low income, from micro enterprises, and on the job, so as to improve their skills of occupational health protection and legal knowledge, and to control the occurrence of occupational or work-related diseases.

【Objective】 To study the concordance of identifying the presence or absence of KIR genes using flow reverse sequence-specific oligonucleotide probe (Flow-rSSO) hybridization and sequencing based typing-PCR (PCR-SBT) methods. 【Methods】 A total number of 131 cases of DNA samples from Han population were subjected to identify the presence or absence of all 16 KIR genes by Flow-rSSO method, and then sequenced at coding sequence for all 14 functional KIR genes using our in-house KIR PCR-SBT assay. The concordance of identifying the presence or absence of all functional KIR genes by Flow-rSSO and PCR-SBT was analyzed. Samples with inconsistent initial results were re-tested using the Flow-rSSO commercial kits with different Lot number, and further tested using the PCR-SSP commercial kit. 【Results】 The presence or absence of 14 functional KIR genes for 129 of 131 samples were completely in accordance via the PCR-SBT and Flow-rSSO methods. Two samples, one with 3DL1 negative, the other with both 2DS3 and 2DS5 negative initially-identified by Flow-rSSO, were actually all positive tested by PCR-SBT. Further retest by Flow-rSSO commercial kits with different Lot number and PCR-SSP commercial kit indicated that the two samples were all positive, which agreed well with PCR-SBT results. 【Conclusion】 In this paper, the initial test results of the presence or absence of KIR genes identified by Flow-rSSO for 2 samples were wrong, which indicated the importance of carrying out the quality control for reagents in KIR gene testing.

To explore the clinical effect, safety and effectiveness of ultrasound-guided rhomboid intercostal and subserratus plane (RISS) block for postoperative analgesia after minimally invasive McKeown esophagectomy (MIE-McKeown), and provide new ideas for the selection of postoperative analgesia programs for minimally invasive esophageal cancer surgery patients.

Objective:To investigate any anti-aging effect of repeated transcranial magnetic stimulation (rTMS) and explore the relationship between the effect and relief of clinical symptoms in patients with Parkinson′s disease (PD).Methods:A total of 108 PD patients were randomly divided into an rTMS group and a control group, each of 54, while another 54 healthy counterparts were selected to form a normal group. In addition to anti-PD drug therapy, the rTMS group was given daily rTMS treatment, 5 days a week for 4 weeks, while the control group received sham rTMS treatment, with no treatment of the normal group. Before the treatment and after 4 weeks of treatment as well as and 1 month after the ending of the treatment, the subjects′ clinical exercise symptoms were evaluated using the Unified Parkinson′s Disease Rating Scale (UPDRS), a timed exercise test and the 10m re-entry exercise test. Non-exercise symptoms were assessed using the Hamilton Depression Scale (HAMD), the Hamilton Anxiety Scale (HAMA) and the Mini-mental State Examination (MMSE). Fasting venous blood samples were analyzed to quantify the serum levels of tumor necrosis factor (TNF), interleukin-6 (IL-6), interleukin-1β (IL-1β) and matrix metalloproteinase-3 (MMP-3).Results:Four weeks and 1 month after the treatment, the average UPDRS scores, exercise test times and 10m re-entry exercise test results of the rTMS group were significantly better than those before treatment and significantly better than those of the control group at the same time point. The rTMS group′s average HAMA, HAMD and MMSE scores, as well as its average P300 latency and amplitude were also significantly better than those of the control group at the same time point and significantly better than those before treatment. After 4 weeks, the average MMP-3 content in the rTMS group was significantly lower than the control group′s average, and after a month the average levels of TNF, IL-6, IL-1β and MMP-3 of the rTMS group were all significantly different from those before treatment and those of the control group. The TNF, IL-6, IL-1β and MMP-3 levels were all positively correlated with the average UPDRS total score.Conclusion:High-frequency rTMS therapy can change the phenotypes related to cell senescence, and thus has good therapeutic effect on motor and non-motor symptoms of PD.

OBJECTIVE：To investigate the potential mechanism of Salvia miltiorrhiza in the treatment of postoperative abdominal adhesion （PAA）. METHODS ：Active components and target genes of S. miltiorrhiza were retrieved from TCMSP database，SwissADME database ，Perl database ，UniProt database and other databases. GeneCards ，OMIM and PubMed database were used to retrieve target genes related to PAA. Venn diagram was drawn by using mapping tool of bioinformatic online database so as to screen the intersecting targets of active component-PAA. STRING platform was adopted to establish target network related to active component-PAA and protein-protein interaction （PPI）network of intersecting targets ，etc.，and to screen hub genes. Gene ontology（GO）and Kyoto Encyclopedia of Genes and Genom es（KEGG）pathway enrichment were carried out by using R 3.6.1 software. Using the protein encoded by hub gene as receptor and tanshinone Ⅱ A as ligand ，the molecular docking was carried out with AutoDock 1.5.6 tool. RESULTS ：A total of 38 active components of S. miltiorrhiza with high gastrointestinal absorption and their corresponding 72 targets，755 PAA-related target genes were identified. Results of Venn diagram showed that there were 33 intersecting targets of active components of chuqi90@163.com S. miltiorrhiza with PAA. Tanshinone ⅡA，dihydrotanshinolac- tone and other components may be important nodes of the target network related to active component-PAA. FOS，APP，ACHE， CASP3 and PTGS2 may be the hub genes in PPI network of intersecting targets. Results of GO enrichment showed that the intersecting targets were mainly concentrated in adrenergic receptor activity ，catecholamine binding ，G protein-coupled amine receptor activity and so on ；KEGG pathway enrichment analysis showed that the intersecting targets were mainly enriched in neuroactive ligand-receptor interaction ，cGMP-PKG signaling pathway ，endocrine resistance ，EGFR-tyrosine kinase inhibitor resistance and calcium signaling pathway.Molecular docking analysis showed that tanshinone ⅡA could form hydrogen bonds with many amino acid residues such as VAL- 580 of proto oncogenes c-Fos ，amyloid precursor protein ，acetylcholinesterase，caspase 3 and prostaglandin G/H synthase 2. CONCLUSIONS ：The active components of S. miltiorrhiza play a role in the treatment of PAA by directly or indirectly acting on neuroactive ligand-receptor interaction ，cGMP-PKG signaling pathway ，endocrine resistance ， EGFR-tyrosine kinase inhibitor resistance resistance and calcium signaling pathway.

【Objective】 To investigate the management of adverse reactions to blood donation(ARBD) in blood services, so as to promote the surveillance of ARBD and improve the quality of blood donation service in Chongqing. 【Methods】 A questionnaire, involving the staff and facilities in blood donation sites as well as the prevention and treatment, the record and report, the following up and data related to ARBD was developed by Chongqing Society of Blood Transfusion in February 2019, and was issued to 18 blood services(1 blood center and its sub-center, 6 central blood stations and 11 hospital blood banks) in the Chongqing via email. The questionnaire was filled in and submitted before March 31 by management personnel participating in the investigation, and the data was collected, collated, revised and analyzed by Excel 2011. 【Results】 A total 19 questionnaires were collected, with the valid rate at 100%(19/19). 78.95%(15/19) of the blood services met the requirements of medical personnel allocation(>6 medical staff) when the number of daily blood collection was more than 60, and 100%(19/19)met the requirements of medical personnel allocation(2 to 6 medical staff) when the number of daily blood collection was less than 60. 89.47%(17/19) of the blood services were equipped with epinephrine hydrochloride, and 84.21%(16/19) with dexamethasone(an anti-allergic drug). There were significant differences in the allocation of other types of drugs. 100.00%(19/19) of the blood services formulated prevention and treatment measures concerning ARBD. In 2019, the incidence of ARBD in Chongqing was reported to be 0.54%(1 958 / 359 871), with the highestas [1.35%(223/16 543)] in subcenters and the lowest [0.32%(179/56 299)] in central blood centers (P<0.05). There was statistical significances in the incidences of ARBD reported by different blood stations(P<0.05). 【Conclusion】 The monitoring and management of ARBD among blood services in Chongqing should be further standardized in terms of staffing allocation, emergency drugs allocation and reporting, so as to gradually realize regional homogenization and ensure blood safety.

Objective The purpose of this study was to evaluate the degree of skin thickening of patients with systemic sclerosis (SSc) by high-frequecy ultrasound,as well as the value of ultrasound.Methods Thirty-one patients with SSc and 31 age-matched and sex-matched healthy control subjects were enrolled.Skin thickness,modified Rodnan skin score (mRss),disease activity index (DA1) and other clinical parameters within and between groups were compared using SPSS 21 software.Student's t test,x2 test or nonparametric testing was performed to compare between groups.The Pearson or Spearman methods were used to test correlation.Sensitivity and specificity of skin thickness detection by high-frequecy ultrasound were evaluated by using receiver operating characteristic (ROC) curve analysis.Results Total thickness of skin (TST) of patientswith SSc were positively correlated to the total mRss (r=0.416,P=0.020) and DAI (r=0.436,P=0.014).The skin thickness of patients with mRss 0,1,2 was higher than CNT [1.45(0.60),1.70(0.30) mm,1.60 (0.30) mm vs 1.30 (0.35) mm,Z=-3.242,-6.577,-5.090,P＜0.01].The cut-off value of TST used as the evaluation of skin change was 7.4 mm by ROC curve analysis,and the sensitivity and specificity of them was 77.40％ and 87.10％ respectively,and patients with thickened skin were more likely to suffer interstitial lung disease (ILD) (16 vs 1,x2=26.004,P=0.014),higher mRss [10(6) vs 4(5),Z=-2.499,P=0.031],DAI [(5.2±2.4) vs (2.3±1.7),t=-3.104,P＜0.01)] and CRP [(8.60 (10.48) mg/L vs 3.52 (4.93) mg/L,Z=-2.276,P=0.038].Conclusion US combined with mRss are helpful to evaluate the changes of skin and disease activity of patients in SSc.US can identify the early and subclinical skin involvement that may precede mRss,providing a more reliable tool for diagnosis,treat efficacy and prediction of organ damage.

Acute ischemic stroke is the most common type of stroke.At present,intravenous thrombolysis within 4.5 h after onset is still the most effective treatment method.Other reperfusion therapies such as endovascular thrombectomy are also shown to be safe and effective.However,some patients will have reocclusion and it is associated with poor outcome.This article reviews the mechanism and possible measures of prevention and treatment for restenosis after thrombolysis.
