Objective:To explore the clinical efficacy of areola approach endoscopic thyroidectomy (AET) and gasless axillary approach endoscopic thyroidectomy (GAET) in the treatment of papillary thyroid carcinoma (PTC) patients.Methods:A total of 96 PTC patients from the Thyroid Surgery Department of Linyi People’s Hospital from May. 2019 to May. 2022 were selected and randomly divided into 48 patients using a random number table method. The areola group received AET, while the armpit group received GAET. The surgical situation, postoperative recovery, relevant biochemical indicators [white blood cell count (WBC), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), parathyroid hormone (PTH), blood calcium] before and after surgery, postoperative pain level, discomfort level, neck function, and complications were compared between the two groups.Results:The surgical time and extubation time of the armpit group were (125.71±15.73) minutes and (3.12±0.53) days, respectively, which were shorter than those of the areola group (137.94±20.02) minutes and (3.48±0.46) days. The intraoperative bleeding volume was (14.19±4.16) mL, which was less than that of the areola group (22.65±7.39) mL, and the number of lymph nodes cleaned was 5.06±1.02, which was more than that of the areola group (4.23±1.14) ( P<0.05) ; there was no significant difference in postoperative drainage volume and hospital stay between the two groups ( P>0.05) ; Peripheral blood WBC in the armpit group on the 1st and 3rd day after surgery [ (5.69±0.15) ×10 9/L, (5.52±0.14) ] ×10 9/L, ESR [ (8.21±0.55) mm/h, (7.64±0.60) mm/h], CRP [ (10.06±1.78) ng/L, (8.93±1.33) ng/L] were lower than those in the areola group [ (5.83±0.21) ×10 9/L, (5.70±0.23) ×10 9/L, (8.87±0.74) mm/h, (8.19±0.68) mm/h, (12.45±1.90) ng/L, (10.45±1.50) ng/L] ( P<0.05). There was no significant difference in the levels of the above biochemical indicators 5 days after surgery ( P>0.05). There was no significant difference in peripheral blood PTH and calcium levels between the two groups on the 1st, 3rd, and 5th postoperative days ( P>0.05). The pain level [ (3.25±0.32) scores, (2.53±0.27) scores, (1.82±0.22) scores] and discomfort level [ (6.85±0.71) scores, (5.24±0.66) scores, (3.51±0.57) scores] in the axillary group were lower than those in the areola group [ (3.78±0.40) scores, (2.89±0.34) scores, (2.06±0.26) scores, (7.46±0.84) scores, (6.09±0.73) scores, (4.16±0.60) scores] on the 1st, 3rd, and 5th postoperative days ( P<0.05). The neck flexion, lateral flexion, and extension range of motion in the axillary group on the 3rd day after surgery were (33.16±3.09) °, (27.63±2.57) °, and (30.44 2.73) °, respectively, which were greater than those in the areola group[ (30.08±2.76) °, (25.14±2.30) °, and (27.98±2.54) °], and the swallowing disorder index was (30.16±4.97) points lower than the (34.83±4.13) points in the areola group ( P<0.05). The incidence of complications in the axillary group was 4.17% (2/48), lower than the 16.67% (8/48) in the areola group. Conclusion:GAET treatment for PTC patients can improve the effect of lymph node dissection, reduce the degree of surgical trauma, postoperative pain and discomfort, accelerate early postoperative recovery of neck function, and reduce complications.

Objective: To explore the neuroprotective effects of the Shaoyao Gancao decoction (SGD) against excitatory damage in PC12 cells and the role of the Src-NR2-nNOS pathway mediation by SGD in regulating γ-aminobutyric acid (GABA)-glutamate (Glu) homeostasis. Methods: N-Methyl-d-aspartic acid (NMDA) was used to establish a PC12 cell excitability injury model. To investigate the neuroprotective effect of SGD, a cell counting kit-8 (CCK-8) assay was used to determine PC12 cell viability, Annexin V/Propidium Iodide (Annexin V/PI) double staining was used to determine PC12 cell apoptosis, and Ca2+ concentration was observed using laser confocal microscopy. GABA receptor agonists and antagonists were used to analyze the neuroprotective interactions between γ-aminobutyric acid (GABA) and NMDA receptors. Additionally, molecular biology techniques were used to determine mRNA and protein expression in the Src-NR2-nNOS pathway. We analyzed the correlations between the regulatory sites of GABA and NMDA interactions, excitatory neurotoxicity, and brain damage at the molecular level. Results: NMDA excitotoxic injury manifested as a significant decrease in cell activity, increased apoptosis and caspase-3 protein expression, and a significant increase in intracellular Ca2+ concentration. Administration of SGD, a GABAA receptor agonist (muscimol), or a GABAB receptor agonist (baclofen) decreased intracellular Ca2+ concentrations, attenuated apoptosis, and reversed NMDA-induced upregulation of caspase-3, Src, NMDAR2A, NMDAR2B, and nNOS. Unexpectedly, a GABAA receptor antagonist (bicuculline) and a GABAB receptor antagonist (saclofen) failed to significantly increase excitatory neurotoxicity. Conclusions Taken together, these results not only provide an experimental basis for SGD administration in the clinical treatment of central nervous system injury diseases, but also suggest that the Src-NR2A-nNOS pathway may be a valuable target in excitotoxicity treatment.

Objective:To assess the changes of peripheral blood NK cells in patients with systemic lupus erythematosus (SLE) following belimumab and classic therapy.Methods:From January 2020 to March 2022, peripheral lymphocyte subsets were detected by flow cytometry in SLE patients treated with Belimumab and classic therapy. The duration of treatment was 24 weeks. A total of 40 treated SLE patients were enrolled. The lymphocyte subsets in healthy donors were used as normal control group. Paired sample t-test, rank-sum test, Spearman correlation and generalized linear mixed model were used for statistical analysis. Results:In contrast to healthy subjects, the numbers of NK cells in SLE patients before treatment were significantly decreased [276.0 (179.8, 384.0) cells/μl vs. 61.4 (43.0, 105.1) cells/μl; Z=-7.32, P<0.001], although that after treatment was higher than that before treatment [61.4 (43.0, 105.1) cells/μl vs. 107.7 (72.5, 186.5) cells/μl; Z= -3.22, P<0.001]. Generalized linear mixed model results showed that the increase in serum levels of C3 ( t= -2.94, P=0.006) and NK cells ( t=-2.25, P=0.031) were associated with a decrease of anti-dsDNA antibody titers. The cutoff value of elevated counts of NK cells after treatment was equal or more than 38.5 cells/μl with a sensitivity of 61.9% and a specificity of 81.2%. Compared with those with elevated counts of NK cells ≤38.5 cells/μl, patients with elevated counts of NK cells >38.5 cells/μl had a bigger difference anti-dsDNA antibody [49.2 (0.2, 207.2) vs. 156.2 (19.8, 260.7); Z=-1.55, P=0.120] and a bigger difference of SLEDAI-2000[4.5 (0.0, 10.0) vs. 13.0 (4.5, 18.0); Z=-2.52, P=0.012]. Conclusion:The change in the numbers of NK cells may serve as biomarkers for evaluating the therapeutic responses of SLE. Combinatory approaches employing belimumab and classic therapy may control SLE disease by increasing the number of NK cells

OBJECTIVE: To investigate the interventional effect of the Chinese herbal preparation Xi Fu Pai Chen(XFPC) on pulmonary inflammation and fibrosis in rats with silicosis. METHODS: A total of 144 adult specific pathogen free male SD rats were randomly divided into 6 groups: blank control group, silicosis model group, drug administration control group and groups of low-dose,medium-dose and high-dose XFPC, with 24 rats in each group. Lung silicosis model was established by single inhalation tracheal instillation method, which was treated with 50.0 g/L silica suspension, in groups except in the blank control group. On the 7 th day of modeling, the rats in the drug administration control group were orally given tetrandrine(5 mg/kg body weight), while those in the low-, medium-and high-dose groups were given 43, 86 and 192 g/L of XFPC by atomization inhalation once a day for 20 minutes, 5 days a week for 4 weeks. At the end of drug administration, the histopathological changes of the lung were observed. The number and classification of cells in bronchoalveolar lavage fluid(BALF)were examined, and the levels of malondialdehyde(MDA) and interferon-gamma(IFN-γ) in BALF were measured by enzyme-linked immunosorbent assay. RESULTS: On the 7 th day after modeling, the body weight in the drug administration control group and XFPC high-dose group decreased compared with the blank control group(P<0.05). On the 35 th day after modeling, the body weights of rats in the other 5 groups were lower than that in the blank control group(P<0.05). The pathological changes of lung tissue(infiltration of inflammatory cells, fibrosis and size of silicon nodule) in drug administration control group and XFPC low-dose group were better than those in silicosis model group by naked eyes and under light microscope. The lung coefficient, the proportion of neutrophils and the level of MDA and IFN-γ in BALF of the drug administration control group and XFPC low-dose group decreased(P<0.05), and the proportion of macrophages in BALF increased(P<0.05) compared with the silicosis model group. There was no significant difference in lung coefficients and the relevant indices of BALF between XFPC medium-, high-dose groups and silicosis model group(P>0.05). CONCLUSION: Low dosage XFPC can improve pulmonary fibrosis and inflammation in rats with silicosis, and its mechanism of action may be related to reducing the levels of IFN-γ and MDA in BALF.

Objective:To investigate the correlation between antiplatelet agents and the risk of ruptured intracranial aneurysm.Methods:Patients with intracranial aneurysm admitted to the Department of Neurology, East Hospital Area of Qingdao Municipal Hospital from June to December 2018 were selected retrospectively. The baseline data of patients and the characteristics of intracranial aneurysms were collected. The independent correlation between antiplatelet agents and the risk of ruptured intracranial aneurysm was identified by the univariable analysis and multivariate logistic regression analysis. Results:A total of 90 patients with intracranial aneurysm were included in the study. There were 31 males (34.44%) and 59 females (65.56%). The median diameter of the aneurysm was 4 mm. Forty-six patients taking antiplatelet agents before being diagnosed with intracranial aneurysm, of which 36 taking aspirin, 3 taking clopidogrel, and 7 taking aspirin+ clopidogrel. There were 31 patients (34.44%) with ruptured aneurysm and 59 (65.56%) with unruptured aneurysm. There were statistical differences in the proportion of patients with age <60 years ( P<0.05), diabetes ( P<0.1), ischemic heart disease ( P<0.05), history of previous stroke or transient ischemic attack ( P<0.01), internal carotid artery aneurysm ( P<0.01), anterior communicating artery aneurysm ( P<0.05), posterior communicating artery aneurysm ( P<0.01) and taking antiplatelet agents before diagnosis ( P<0.1) between the ruptured group and the unruptured group. Multivariate logistic regression analysis showed that age <60 years (odds ratio[ OR] 4.116, 95% confidence interval [ CI] 1.337-12.673; P=0.014), anterior communicating artery aneurysm ( OR 5.015, 95% CI 1.155-22.559; P=0.032) and posterior communicating artery aneurysm ( OR 68.796, 95% CI 6.762-699.951; P<0.001) were the independent risk factors for ruptured intracranial aneurysm, and taking antiplatelet agents was an independent protective factor for ruptured intracranial aneurysm ( OR 0.320, 95% CI 0.104-0.992; P=0.048). Conclusions:Taking antiplatelet agents, especially aspirin, does not increase the risk of ruptured intracranial aneurysm, but may be a protective factor of ruptured intracranial aneurysm. Unruptured aneurysms are not contraindications for antiplatelet therapy in patients with clear indications.

Objective:To investigate the distribution of fungal species and their sensitivity to antifungal drugs in children with invasive fungal infections.Methods:All the fungal strains primarily isolated from the sterile parts of children in Beijing Children′s Hospital, Capital Medical University from January 2010 to December 2016 were analyzed.The sensitivity of strains to 5-Fluorocytosine, Fluconazole, Amphotericin B, Itraconazole and Voriconazole was tested using ATB-FUNGUS 3 yeast drug sensitivity test strip in accordance with the standards of Clinical and Laboratory Standards Institute M27-A2.Statistical analysis of data was performed using WHONET 5.6 software.Results:Among 236 fungi isolated from aseptic samples, 64.0% (151 strains) were from blood, 22.9%(54 strains) from cerebrospinal fluid, 3.8%(9 strains) from bone marrow, 3.8%(9 strains) from ascites, 3.4%(8 strains) from pleural effusion and 2.1%(5 strains) from tissues.The top 3 dominant species detected in the 236 strains of fungi were Candida spp.(175 strains, 74.2%), Cryptococcus neoformans (31 strains, 13.1%), and Saccharomyces spp.(9 strains, 3.8%). Among the Candida spp., the main isolates were Candida albicans (107 strains, 61.1%), Candida parapsilosis (33 isolates, 18.9%), and Candida tropicalis (13 isolates, 7.4%). Rare fungi of Penicillium marneffei, Exophiala spp.and Rhizopys spp.were also detected. Candida spp.was 100% sensitive to Amphotericin B. Cryptococcus neoformans was 100% sensitive to Fluconazole, Voliconazole and Amphotericin B. Conclusions:The most common strain isolated from pediatric patients with invasive fungal infections is Candida spp., especially Candida albicans. Cryptococcus neoformans causes central nervous system and systemic disseminated infections that can′t be ignored.Amphotericin B has higher antibacterial activity against Candida spp.and Cryptococcus neoformans.Separation of species of invasive fungal infections and monitoring of drug resistance in children should be strengthened to effectively control invasive fungal infections and facilitate rational use of antifungal drugs.

Objective: Understanding mental health status of students with learning disabilities in Beijing to provide a basis for mental health promotion of students with learning disabilities. Methods: By means of random cluster sampling, 5 787 enrolled students in grade one and grade two of 11 public junior middle schools in Beijing were selected as the survey subjects. A self designed questionnaire was used to investigate the students’ learning disabilities and mental health status through anonymous self filling. Results: About 11.6% students self reported learning disabilities. The proportions of students with learning difficulty in mathematical reasoning and calculation were higher, 44.1% and 40.7% respectively. The reported rate of mental health problems was 38.3%. The top four of the 10 symptoms were obsessive compulsive symptoms, learning pressure, emotional instability and anxiety(2.19±0.77)(2.17±0.99)(2.09±0.90)(2.07±1.08). Compared with students without learning disabilities, students with self reported learning disabilities had poorer mental health status(OR=1.47), and learning disabilities were related to most factors of mental health. Different types of learning disabilities were associated with different mental health factors. Conclusion Mental health problems of students with learning disabilities are higher than that of students without learning disabilities. It is necessary to strengthen the mental health support for students with learning disabilities and improve their mental health.

The overall quality needs to be improved.

The results of studies on the association between tea consumption and Parkinson’s disease (PD) have been inconsistent. Therefore, the aim of this study was to perform an updated meta-analysis to better resolve any association between tea consumption and PD. We searched PubMed, Embase, and the Cochrane Library– from their commencement to November 2016 – for qualified studies that evaluated the associations between tea drinking and risk of PD. A total of nine case–control studies and three prospective cohort studies were included. The meta-analysis showed that tea consumption was associated with a reduced risk of developing PD(OR, 0.82; 95% CI, 0.69–0.98) when case–control studies and prospective cohort trials were considered together. Subgroup analysis on the category of tea consumption and risk of PD showed that black tea was not associated with PD (OR: 0.89; 95% CI, 0.64–1.24; I2 =0.0%), but other kinds of tea was associated with a reduced risk of developing PD (OR: 0.67; 95% CI, 0.48–0.95; I2 =0.0%). Subgroup analysis on the dose of tea consumption and PD risk showed that drinking more than one cup of tea daily was associated with a reduced risk of developing PD in case–control studies (OR: 0.38; 95% CI, 0.22–0.66; I2 =0.0%). No indication of publication bias was found. In conclusion, the current evidence showed that tea consumption was associated with a reduced risk of developing PD. The results of our subgroup analysis suggested that people who drinking more than one cup of non-black tea daily might have a reduced risk of developing PD
