Persistent left superior vena cava is a rare venous variant that is often combined with cardiovascular malformations. In thoracic surgery, especially mediastinal tumor resection, neglect of this variant may make the surgery difficult and risky, and careful preoperative imaging interpretation and adequate preoperative evaluation play an important role in the perioperative safety of the patient. In this paper, we reported a case of a 17-year-old female patient with a persistent left superior vena cava combined with mediastinal tumors. She was successfully discharged 5 days after thoracoscopic surgery, and after 3 years of postoperative follow-up, no tumor recurrence was observed.

Objective To observe the efficacy and safety of repetitive transcranial magnetic stimulation(rTMS)on refractory tinnitus and the differences of resting-state functional magnetic resonance imaging(rs-fMRI)imaging between before and after treatment,and to explore the possible central mechanism of rTMS regulation of tinnitus.Methods Thirty-seven patients with refractory tinnitus admitted in Affiliated Hospital of North Sichuan Medical College from September 2022 to February 2023 were selected and were divided into experimental group(n=20)and control group(n=1 7).The experimental group was given true rTMS treatment,and the control group was given sham stimulation with the same parameters.Tinnitus handicap inventory(THI)score,tinnitus loudness visual analogue scale(VAS)score and rs-fMRI scan were performed before and after treatment.Regional homogeneity(ReHo)was calculated after scanning,and the different brain regions were selected as the area of interest(ROI)and the whole brain functional connection(FC)was performed.Results There were no significant differences in age,gender,education level,tinnitus side,course of disease,hearing level,self-rating depression scale,self-rating anxiety scale the experimental group and control group.There were no significant differences in THI and VAS scores between the two groups before treatment;the THI and VAS scores in the experimental group decreased after 2 weeks of rTMS treatment(P＜0.001),while there was no significant difference in the two scores in the control group before and after treatment.Only 3 patients in the experimental group experienced left facial muscle tremor or transient mild scalp pain during treatment,without other serious side effects.The ReHo of the left cerebellar area 9 increased in the experimental group after rTMS(P＜0.005);the ReHo values in the right inferior temporal gyrus,left posterior central gyrus and left anterior central gyrus increased in the control group after intervention(P＜0.005).The FCs between the right inferior temporal gyrus and the left orbital inferior frontal gyrus,the left anterior cingulate gyrus increased in the experimental group(P＜0.005),and FC between the right inferior temporal gyrus and the left superior marginal gyrus decreased(P＜0.005).The FCs between the right cuneus and the left fusiform gyrus,right superior occipital gyrus decreased in the experimental group after rTMS(P＜0.005).The FC between the right cuneus and the left fusiform gyrus increased in the control group after intervention(P＜0.005),while other FCs remained unchanged.Conclusions rTMS has a certain therapeutic effect on refractory tinnitus with higher safety;regulation of auditory brain network and related non-auditory brain network may be one of the central mechanisms of rTMS treating refractory tinnitus.

Background Di(2-ethylhexyl) phthalate (DEHP) is the highest consumed and the most widely used phthalic acid ester, their effects on lipid metabolism have attracted the attention of many scholars. However, the associated mechanism is still unclear. Objective To observe the effect of DEHP on lipid metabolism in rats, probe its possible mechanism, and provide a research basis for the effect of DEHP on human lipid metabolism. Methods Forty healthy male SD rats were randomly divided into 4 groups: solvent control (0 mg·kg⁻¹ DEHP), low DEHP (187 mg·kg⁻¹), medium DEHP (375 mg·kg⁻¹), and high DEHP (750 mg·kg⁻¹) groups. DEHP was administered by oral gavage for 6 d per week, consecutively 8 weeks. The rats were weighed once a week during the exposure period. At 24 h after the last exposure, the rats were anesthetized with 20% urethane and sacrificed by apical puncture. Rat livers were harvested and weighed before hematoxylin-eosin (HE) histopathological observation. Reverse transcription-polymerase chain reaction (RT-PCR) was used to detect the mRNA levels of lipid metabolism-related genes Janus kinase 3 (JAK3), signal transducer and activator of transcription 5b (STAT5b), and peroxisome proliferator-activated receptor γ (PPARγ) in liver, and Western blot was used to detect the expression levels of lipid metabolism-related proteins JAK3, STAT5b, and PPARγ in liver. Results Compared with the control group, there was no significant difference in the body weight gain of the rats in each group (P>0.05). The liver organ coefficients of the DEHP exposure groups were higher than that of the control group (P<0.001), and increased with higher DEHP dosages. The level of high-density lipoprotein cholesterol (HDL-C) in serum decreased in all DEHP exposure groups (P<0.05), and the level of low-density lipoprotein cholesterol (LDL-C) in serum increased in the high DEHP group (P<0.05). The results of liver histopathological morphology showed that the hepatocytes of each DEHP group were enlarged and edematous in varying degrees, with loose stroma and irregular arrangement of cells, which were manifested as inflammatory cell infiltration and fatty degeneration of liver cells. Compared to the control group, the mRNA levels of JAK3, STAT5b, and PPARγ in liver tissues of rats in each DEHP group decreased (P<0.001). Compared to the control group, the relative expression levels of JAK3 in each DEHP group decreased (P<0.05), and the relative expression levels of STAT5b and PPARγ in the medium and high DEHP groups decreased (P<0.05). Conclusion DEHP exposure can induce abnormal lipid metabolism in rats, and the mechanism may be related to DEHP inhibiting the activation of JAK3/STAT5b/PPARγ signaling pathway.

Objective:To explored the feasibility and efficacy of a rapid ramp-up,2-week maximum regimen of venetoclax(VEN)plus low-dose cytarabine(LDAC)for treating relapsed/refractory acute myeloid leukemia(R/R AML).Methods:We retrospectively analyzed patients with venetoclax-na?ve R/R AML treated with VEN+LDAC between October 2018 and November 2023.On the first day,patients received 200 mg of VEN,and the dose was quickly increased to 400 mg for the rest of the treatment;cytarabine was administered subcutaneously at a low dose of 20 mg/m2/day.The treatment duration was 10 or 14 days,depending on the condition of bone marrow hyperplasia determined on the 8th day of treatment.No patients received venetoclax monotherapy.All patients responding to salvage therapy received VEN+LDAC until disease progression or transplantation.Results:Among the patients,the median follow-up duration was 27.5 months.No clinical mani-festations of tumor lysis syndrome(TLS)occurred during the treatment.The overall response rate(ORR)was 68.75%,including four com-plete responses(CR),one complete remission with incomplete hematologic recovery(CRi),and six partial responses(PR).The median num-ber of best treatment result cycles was one cycle.The median overall survival(OS)in the whole cohort was 5.8(0.5-47.2)months;the medi-an progression-free survival(PFS)was 22.2(7.3-42.9)months.The major adverse events were grade 3-4 hematologic adverse events and in-fections.Conclusions:The 8th-day myelosuppression-adjusted VEN+LDAC regimen is a feasible salvage option with a reasonable safety pro-file in patients with venetoclax-na?ve R/R AML.Most patients tolerated the 14-day treatment;the response was generally rapid in the re-sponding patients.

Purpose To observe the CT imaging features of dermatomyosistis patients with anti-melanoma differentiation related genes 5(MDA-5),and to analyze the relationship between CT imaging indicators and short-term prognosis of patients.Materials and Methods Sixty-seven MDA-5-positive dermatomyosistis patients admitted to China-Japan Friendship Hospital from January 2017 to December 2018 were retrospectively included.Prognosis of included patients in one year were followed-up.Analysis of the relationship between chest CT imaging and short-term poor prognosis.Results Among 67 patients,nine patients died in one year.There was a statistically significant difference between the two groups(the death group and the survivor group)in the interstitial lung disease(ILD)imaging types(χ2=0.198,P=0.025)and pulmonary/aortic diameter ratios(U=103.0,P=0.004).CT imaging of dermatomyosistis-ILD with anti-MDA5 antibody positive patients showed organizing pneumonia.Mortality of diffuse alveolar damage type was significantly higher than that of other types.Logistic regression analysis showed that pulmonary/aortic diameter ratio(OR:4.208,P=0.002)was a strong independent risk factor for the death of patients with anti-MDA5 antibody.Conclusion Most patients with anti-MDA5 antibody positive dermatomyositis show ILD,with the main feature of organic pneumonia.Patients with poor prognosis within 1 year have different types of ILD,while the pulmonary/aortic diameter ratio is a strong independent risk factor for the death of dermatomyosistis-ILD with anti-MDA5 antibody positive patients.

Objective: This study aimed to determine the predictive performance of non-contrast CT (NCCT) signs for hemorrhagic growth after intracerebral hemorrhage (ICH) when stratified by onset-to-imaging time (OIT). Materials and Methods: 1488 supratentorial ICH within 6 h of onset were consecutively recruited from six centers between January 2018 and August 2022. NCCT signs were classified according to density (hypodensities, swirl sign, black hole sign, blend sign, fluid level, and heterogeneous density) and shape (island sign, satellite sign, and irregular shape) features. Multivariable logistic regression was used to evaluate the association between NCCT signs and three types of hemorrhagic growth: hematoma expansion (HE), intraventricular hemorrhage growth (IVHG), and revised HE (RHE). The performance of the NCCT signs was evaluated using the positive predictive value (PPV) stratified by OIT. Results: Multivariable analysis showed that hypodensities were an independent predictor of HE (adjusted odds ratio [95% confidence interval] of 7.99 [4.87–13.40]), IVHG (3.64 [2.15–6.24]), and RHE (7.90 [4.93–12.90]). Similarly, OIT (for a 1-h increase) was an independent inverse predictor of HE (0.59 [0.52–0.66]), IVHG (0.72 [0.64–0.81]), and RHE (0.61 [0.54– 0.67]). Blend and island signs were independently associated with HE and RHE (10.60 [7.36–15.30] and 10.10 [7.10–14.60], respectively, for the blend sign and 2.75 [1.64–4.67] and 2.62 [1.60–4.30], respectively, for the island sign). Hypodensities demonstrated low PPVs of 0.41 (110/269) or lower for IVHG when stratified by OIT. When OIT was ≤ 2 h, the PPVs of hypodensities, blend sign, and island sign for RHE were 0.80 (215/269), 0.90 (142/157), and 0.83 (103/124), respectively. Conclusion Hypodensities, blend sign, and island sign were the best NCCT predictors of RHE when OIT was ≤ 2 h. NCCT signs may assist in earlier recognition of the risk of hemorrhagic growth and guide early intervention to prevent neurological deterioration resulting from hemorrhagic growth.

Objective To preliminarily verify the effectiveness and safety of bloodletting combined with drug bamboo cups in intervention of degenerative lumbar spinal stenosis,and to explore the prognostic factors that affect the efficacy of TCM regimens in the treatment of DLSS.Methods 64 consecutive patients with degenerative lumbar spinal stenosis were enrolled.Bloodletting combined with drug bamboo cup intervention was used.Acupoints were selected and treated with the same length of the governor channel of the lumbar spine,the first and second side lines of the bladder meridian and Ashi point,weekly 2 times,8 times per course,2 consecutive courses of treatment.Before treatment,after treatment,and 1 month follow-up,the changes of the patient's lumbar spinal stenosis specific scale(SSM),modified Oswestry dysfunction index(ODI),and 12 health survey summary scores(SF-12)were observed.Using SSM symptom or function score≥0.5,the criteria for grouping were first single-factor analysis,and then logistic regression was used to analyze the prognostic factors of the treatment.Results After 2 courses of treatment,the patient's SSM symptom score(2.25±0.56),SSM function score(2.06±0.67),ODI index(15.49±8.72),and SF-12 physiological score(36.31±7.35)were more significant than before treatment Improved,the difference was statistically significant(P<0.05),the SF-12 psychological score(49.70±9.47),the difference was not statistically significant compared with before treatment(P>0.05);the patient's SSM symptom score(2.22±0.54)was followed up for one month,SSM function score(2.09±0.66),ODI index(15.53±8.23),SF-12 physiological score(36.55±7.25),SF-12 psychological score(50.62±9.17),which are significantly better than before treatment,and the difference is statistically significant(P<0.05),the difference was not statistically significant(P>0.05)after 2 courses of treatment.The univariate logistic regression analysis of each influencing factor showed that:BMI,baseline symptom dimension,baseline functional dimension,foraminal stenosis,lateral recess stenosis,and two-stage stenosis had statistically significant differences between the effective and ineffective groups(P<0.05).Conclusion Bloodletting combined with drug bamboo cups has a certain clinical effect on degenerative lumbar spinal stenosis.

Background Occupational pneumoconiosis is the most common occupational disease in Qinghai Province and China. From the perspective of public health, it is important to assess the disease burden using disability-adjusted life years (DALY) and economic losses. Objective To evaluate the disease burden of occupational pneumoconiosis in Qinghai Province, and to provide a basis for the formulation and implementation of relevant prevention and control strategies. Methods Based on the registered data, a database of occupational pneumoconiosis cases confirmed and reported in Qinghai Province was established. The survival status and death dateof occupational pneumoconiosis patients from 2015 to 2019 were confirmed by on-site visit, telephone survey, matching search of Death Information Registration and Management System, and consulting other departments. The life loss due to occupational pneumoconiosis from 2015 to 2019 was assessed using DALY as an indicator and data from the Global Burden of Disease 2019 (GBD 2019) study. Inpatients with officially diagnosed occupational pneumoconiosis from a hospital in Qinghai Province in 2019 were selected as study subjects, the direct economic loss was evaluated with hospitalization expenses, and the indirect economic loss due to occupational pneumoconiosis in Qinghai Province in 2019 was calculated by human capital approach. Results From 2015 to 2019, 505 new cases of occupational pneumoconiosis were reported in Qinghai Province, and there were 348 death cases. Prevalent cases and years lost due to disability (YLD) due to occupational pneumoconiosis were increased, while DALY and years of life lost (YLL) due to occupational pneumoconiosis decreased firstly and then increased. In each year, there were 87% or more of the DALY, YLL, or YLD attributed to silicosis and coal workers' pneumoconiosis. In 2019, the occupational pneumoconiosis-associated DALY was 2173.55 person years. The total hospitalization expense incurred by 42 inpatients with occupational pneumoconiosis was 1256345.19 yuan. The total hospitalization expense and average daily cost of the inpatients with stageⅡand Ⅲ pneumoconiosis were higher than that of the inpatients with stageⅠ (P<0.05), and the hospitalization expense was higher in the ≥60 years age group than in the <60 years age group (P<0.05). In 2019, the indirect economic burden incurred by occupational pneumoconiosis in Qinghai Province was 44108581.65 yuan, and accounted for 0.15‰ of the gross domestic product (GDP) of the province. Conclusion The disease burden associated with occupational pneumoconiosis in Qinghai Province are outstanding. Silicosis and coal workers' pneumoconiosis are the key contributors. Targeted intervention measures including dust hazard control, enterprise management, follow-up and rehabilitation management of pneumoconiosis should be taken to prevent and control the occurrence and progression of pneumoconiosis and alleviate disease burden of pneumoconiosis.
