Background The mental health problems of employees in administrative organs and public institutions are highly valued.However,there is a lack of understanding regarding the mental health status of employees in provincial and municipal administrative organs and public institutions in Qinghai region.Objective To analyze the anxiety and depression of employees in provincial and municipal administrative organs and public institutions in Qinghai region,so as to provide references for promoting their mental health and intervening in psychological problems.Methods From October 23 to 28,2022,a total of 3 096 employees in provincial and municipal administrative organs and public institutions in Qinghai region were enrolled using stratified cluster sampling technique,and were assessed using Self-rating Anxiety Scale(SAS)and Self-rating Depression Scale(SDS).Results A total of 1797(58.04％)employees in municipal and above administrative organs and public institutions in Qinghai region completed a valid questionnaire survey.Depressive symptoms were noted in 579(32.22％).SDS scores yielded statistical difference among the selected employees of different ethnicities,types of job positions and educational levels(F=9.074,101.488,4.477,P<0.01),and the severity of depressive symptoms also demonstrated statistical difference among the selected employees with different ethnicities,educational levels and types of job positions(H=49.196,17.028,160.848,P<0.01).Anxiety symptoms were detected in 711(39.57％)employees.SAS scores exhibited statistical difference among the employees with different genders,ages,ethnicities,educational levels,marital status and types of job positions(t=-4.571,F=6.648,3.950,5.243,12.008,22.253,P<0.01).Statistical differences were also illustrated in the severity of anxiety symptoms among the selected employees with different ages,genders,ethnicities,educational levels,marital status and types of job positions(H=24.361,-3.788,28.365,24.268,25.976,56.204,P<0.01).Conclusion About one-third of employees in municipal and above administrative organs and public institutions in Qinghai region may have symptoms of depression and anxiety.The depression symptoms are more severe among Tibetan people,those with low education levels and ordinary civil servants.The anxiety symptoms are more severe among employees aged 30 and below,those with low education levels,unmarried and those in technical positions.

Objective To analyze the clinical characteristics of pulmonary tuberculosis patients compli-cated with infection of Nocardia farcinica aiming to improve the diagnosis and treatment the disease.Methods The clinical data of 22 cases of pulmonary tuberculosis complicated with Nocardia farcinica infection admitted to Guang-zhou Chest Hospital from June 2020 to December 2023 were collected and the clinical manifestations,imaging,laboratory tests,treatment process,and disease outcomes were retrospectively analyzed.Results Among the 22 patients,there were 13 males and 9 females,aged 20～86 years,with a median age of 52 years.Common clinical manifestations included cough(22/22),sputum(21/22),and underlying diseases(13/22).One case was positive for cerebrospinal fluid culture,and 21 cases were positive for sputum culture.The culture period was 5～26 days,with a median culture period of 18 days.The imaging manifestations were mainly plaques,plaques and cavities,and the lesions were spread in both lungs(17/22)and cavities(11/22).After anti-tuberculosis treatment,the absorption of lung lesions in some patients was poor,and the absorption of the lesions was improved after anti-nocardia treat-ment.8 cases were cured,13 cases were improved and 1 case died.Conclusion The clinical symptoms of pa-tients with pulmonary tuberculosis complicated with Nocardia farcinica were atypical,the culture period of Nocardia was long,and the imaging manifestations were similar to pulmonary tuberculosis,which is prone to misdiagnosis and missed diagnosis.For patients with poor response to anti-tuberculosis treatment and slow lesion absorption,the possi-bility of a concurrent Nocardia infection should be considered.

Objective To compare the short-term clinical effects of unilateral dual-channel endoscopic discectomy(UBED)and percutaneous endoscopic intervertebral discectomy(PEID)in the treatment of L5S,Lumbar disc herniation,LDH.Methods From January 2019 to January 2021,a total of 57 cases of L5S,LDH treated by UBED or PEID were analyzed retrospectively,including 30 cases in UBED group and 27 cases in PEID group.The operation time,intraoperative fluoroscopy times,postoperative hospitalization days and surgical complications were compared between the two groups.The visual analogue scale(VAS)and oswestry disability index(ODI)were used to compare the postoperative quality of life of the two groups,and the modified MacNab criteria was used to evaluate the clinical efficacy in the last follow-up.Results The operation time of UBED group and PEID group was(75.30±8.44)minutes and(68.37±4.63)minutes,respectively,and the difference between the two groups was statistically significant(P＜0.05).VAS and ODI of 1 week,3 months,1 year and 1.5 years after surgery in 2 groups were significantly decreased compared with those before surgery,with statistical significance(P＜0.05).The VAS score of low back pain in UBED group was higher than that in PEID group[(3.87±1.14)points vs(2.70±0.67)points]at 1 week after surgery(P＜0.05),and there was no significant difference in VAS and ODI at the other time points(P＞0.05).There was no statistical difference in the results of modified MacNab criteria in the last follow-up(P＞0.05).There were 2 cases of dural tear in PEID group,1 case of dural tear in UBED group and 1 case of temporary nerve root injury in PEID group after operation,all of which were cured after symptomatic treatment.Conclusion Compared with PEID,UBED has a longer operation time,more trauma and more obvious low back pain in the short term after operation.The short-term curative effect of the two operations on L5S1 LDH is similar,the incidence of complications is low,and the times of fluoroscopy are few.Both operations are safe and effective.

Objective:To investigate the clinical and pathological characteristics of acquired immunodeficiency syndrome (AIDS) patients with intestinal Talaromycosis marneffei (TM) infection. Methods:A total of 64 AIDS patients who underwent colonoscopy in Guangzhou Eighth People′s Hospital from January, 2010 to December, 2018 were retrospectively collected. Among them, 32 patients were co-infected with TM (AIDS with intestinal TM infection group) and 32 patients were not (AIDS without intestinal TM infection group) according to the colonic mucosa pathology. The clinical manifestations and pathological differences were compared between the two groups. Nonparametric rank sum test and Fisher exact probability method were used for statistical analysis.Results:The proportions of patients presented with fever, cough, retroperitoneal lymph nodes tume faction, nausea and vomiting, abdominal muscle tension, abdominal tenderness and rebound pain in AIDS with intestinal TM infection group were 28 (87.5%), 16 (50.0%), 13 (40.6%), 9 (28.1%), 8 (25.0%), 20 (62.5%) and 12 (37.5%), respectively, which were all significantly higher than those in AIDS without intestinal TM infection group 11 (34.4%), 6 (18.8%), 3 (9.4%), 2 (6.2%), 1 (3.1%), 8 (25.0%) and 1 (3.1%), respectively, the differences were statistically significant (Fisher exact test, all P<0.05). The median counts of peripheral blood CD4 + T lymphocyte, lymphocytes, monocytes, hemoglobin, platelet and albumin in AIDS with intestinal TM infection group were 13.5/μL, 0.30×10 9/L, 0.16×10 9/L, 88 g/L, 122×10 9/L and 23.5 g/L, respectively, which were all significantly lower than those in AIDS without intestinal TM infection group 207.0/ μL, 1.35×10 9/L, 0.35×10 9/L, 128 g/L, 201×10 9/L and 37.5 g/L, respectively, the differences were all statistically significant ( Z=-6.111, -6.191, -4.273, -5.353, -2.974 and-6.666, respectively, all P<0.05). Multivariate logistic regression analysis showed that CD4 + T lymphocytes <50/μL, hemoglobin <90 g/L and fecal occult blood positive were independent risk factors for AIDS with intestinal TM infection. The main manifestations of colonoscopy in AIDS with intestinal TM infection group were discontinuous ulcers (31.2%(10/32)), erosion (31.2%(10/32)) or co-exitance of ulcer and erosion (21.9%(7/32)), while suspected tumor-like eminence lesions were less common (15.6%(5/32)). The pathological features of colon mucosa were ulcer and/or erosion (53.1%(17/32)), chronic inflammation (46.9%(15/32)) and inflammatory granuloma (43.8%(14/32)). Oval or round spore with apparent septum could be seen by special staining. In AIDS with intestinal TM infection group, 27 patients were cured or improved, five patients died or deteriorated, while all patients in the AIDS without intestinal TM infection group improved after treatment without death. Conclusions:There are no specific gastrointestinal symptoms in AIDS patients with intestinal TM infection, while the patients present with decreased immunological cells and multiple colony pathological features. Specific fungal spores can be seen.

Trauma is the leading cause of death for people under 40 years old in the world. At present, the rescue and treatment system of trauma patients in China is not yet well established, and the mortality of trauma patients is higher than those in the developed countries. Improving the treatment system is the key to reducing the trauma mortality. In order to innovate the service mode of trauma first aid, further promote the establishment of regional trauma first aid system, improve the ability of trauma treatment, reduce the mortality and disability rate of trauma patients in Jiangxi Province, recently Health Commission of Jiangxi Province and the First Affiliated Hospital of Nanchang University have reached a consensus on the establishment of Jiangxi trauma first aid center. In order to provide reference for the construction of trauma treatment system, the author analyzes the following aspects including functional positioning, basic requirements, organization management, and evaluation of core indicators.

OBJECTIVETo study the expression of EpCAM and E-cadherin in papillary thyroid carcinoma and to analyze its correlation with various clinicopathologic parameters.

METHODSImmunohistochemical study for EpCAM and E-cadherin was carried out in 91 cases of papillary thyroid carcinoma. Twenty-four cases of papillary hyperplasia of thyroid were used as controls.

RESULTSIn all of the 24 cases of papillary hyperplasia, EpCAM was located on the cell membrane, while in the 91 cases of papillary thyroid carcinoma studied, EpCAM was located within the cytoplasm, with 36.3% (33/91) showing nuclear localization as well. In all the papillary hyperplasia cases studied, E-cadherin showed membranous expression. E-cadherin expression was reduced in 84.6% (77/91) of papillary thyroid carcinoma, as compared with the surrounding native thyroid parenchyma. Amongst the 33 cases of papillary thyroid carcinoma which showed nuclear localization of EpCAM, 30 cases also showed reduced E-cadherin expression. There was a positive correlation between nuclear expression of EpCAM and loss of E-cadherin expression (P = 0.000; Spearman correlation coefficient = 0.857). Nuclear expression of EpCAM correlated with follicular variant of papillary thyroid carcinoma and presence of extrathyroidal extension ( P = 0.037 and 0.033, respectively). Loss of E-cadherin expression correlated with age of patients and presence of lymph node metastasis (P = 0.018 and 0.010, respectively).

CONCLUSIONSE-cadherin expression is reduced in papillary thyroid carcinoma, as compared with native thyroid parenchyma and papillary hyperplasia. Papillary thyroid carcinoma shows loss of EpCAM membranous expression and increased cytoplasmic/nuclear accumulation. Detection of these two markers may provide a valuable reference in defining the biologic behaviors of papillary thyroid carcinoma, including extrathyroidal extension and lymph node metastasis.

OBJECTIVETo compare the clinical characteristics of rifampin-dependent (R-dependent Mycobacterium tuberculosis) and rifampin-resistant (R-resistant Mycobacterium tuberculosis) patients with pulmonary tuberculosis.

METHODSThe clinical data including the demographic data, age groups, course of disease, history of chemotherapy with anti-TB drugs, and results of drug susceptibility test were collected from 61 cases of R-dependent pulmonary tuberculosis and 148 cases of R-resistant pulmonary tuberculosis treated between October, 2008 and January, 2012.

RESULTSMost of the R-dependent and R-resistant patients were between 30 and 44 years of age. The R-dependent patients included 12 receiving the first treatment patients and 49 with previous treatments, and the R-resistant patients included 11 without and 137 with previous treatments. The multi-drug resistant rate was 80.3% in R-dependent group, as compared to 92.6% in R-resistant group.

CONCLUSIONMost of the patients infected with R-dependent Mycobacterium tuberculosis are young or middle-aged, often having serious disease conditions. Detecting rifampin dependence is important for patients with initial treatment failure. Multi-drug resistance therapy guideline should be applied to patients infected with R-dependent Mycobacterium tuberculosis to improve the cure rate.
