Efficacy of alcohol septal ablation in mildly symptomatic or severely symptomatic patients with hypertrophic obstructive cardiomyopathy / 中华心血管病杂志

Objective: To compare the prognosis of mildly or severely symptomatic patients with obstructive hypertrophic cardiomyopathy (OHCM) who underwent alcohol septal ablation (ASA). Methods: This retrospective study cohort consisted of patients with OHCM who received ASA treatment in Beijing Anzhen Hospital, Capital Medical University from March 2001 to August 2021. These patients were divided into mildly and severely symptomatic groups according to the severity of clinical symptoms. Long-term follow-up was conducted, and the following data were collected: duration of follow-up, postoperatire treatment, New York Heart Association (NYHA) classification, arrhythmia events and pacemaker implantation, echocardiographic parameters, and cause of death. Overall survival and survival free from OHCM-related death were observed, and the improvement of clinical symptoms and resting left ventricular outflow tract gradient (LVOTG) and the incidence of new-onset atrial fibrillation were evaluated. The Kaplan-Meier method and log-rank test were used to determine and compare the cumulative survival rates of the different groups. Cox regression analysis models were used to determine predictors of clinical events. Results: A total of 189 OHCM patients were included in this study, including 68 in the mildly symptomatic group and 121 in the severely symptomatic group. The median follow-up of the study was 6.0 (2.7, 10.6) years. There was no statistical difference in overall survival between the mildly symptomatic group (5-year and 10-year overall survival were 97.0% and 94.4%, respectively) and the severely symptomatic group (5-year and 10-year overall survival were 94.2% and 83.9%, respectively, P=0.405); there was also no statistical difference in survival free from OHCM-related death between the mildly symptomatic group (5-year and 10-year survival free from HCM-related death were 97.0% and 94.4%, respectively) and the severely symptomatic group (5-year and 10-year survival free from HCM-related death were 95.2% and 92.6%, respectively, P=0.846). In the mildly symptomatic group, NYHA classification was improved after ASA (P<0.001), among which 37 patients (54.4%) were in NYHA class Ⅰ, and the resting left ventricular outflow tract gradient (LVOTG) decreased from 67.6 (42.7, 90.1) mmHg (1 mmHg=0.133 kPa) to 24.4 (11.7, 35.6) mmHg (P<0.001). In severely symptomatic group, NYHA classification was also improved post ASA (P<0.001), among which 96 patients (79.3%) improved by at least one NYHA classification, and the resting LVOTG decreased from 69.6 (38.4, 96.1) mmHg to 19.0 (10.6, 39.8) mmHg (P<0.001). The incidence of new-onset atrial fibrillation was similar between the mildly and severely symptomatic groups (10.2% vs. 13.3%, P=0.565). Cox multivariate regression analysis showed that age was an independent predictor of all-cause mortality in OHCM patients post ASA (HR=1.068, 95%CI 1.002-1.139, P=0.042). Conclusions: Among patients with OHCM treated with ASA, overall survival and survival free from HCM-related death were similar between mildly symptomatic group and severely symptomatic group. ASA therapy can effectively relieve resting LVOTG and improve clinical symptoms in mildly or severely symptomatic patients with OHCM. Age was an independent predictor of all-cause mortality in OHCM patients post ASA.

The efficacy analysis of moderately hypofractionated IMRT combined with androgen deprivation therapy for locally advanced prostate cancer / 中华放射医学与防护杂志

Objective:To investigate the efficacy and adverse reactions of moderately hypofractionated intensity modulated radiation therapy (IMRT) combined with androgen deprivation therapy (ADT) for locally advanced prostate cancer (LAPC).Methods:This study retrospectively analyzed the medical records of 40 LAPC patients who were admitted in The Second Hospital of Dalian Medical University during 2014-2020. The planning gross target volume (PGTV) dose for prostate gland and seminal vesicle gland was 64.8-70.0 Gy/25-28 f, 2.4-2.8 Gy/f and the dose of PGTVnd in 20 cases with positive pelvic lymph nodes was 60.0-64.4 Gy/25-28 f, 2.3-2.4 Gy/f. The dose of planning target volume (PTV) for the drainage area of pelvic lymph nodes was 45.0-50.4 Gy/25-28 f. The enrolled patients were treated with long-term ADT, including neoadjuvant, simultaneous, and adjuvant therapies. The efficacy and adverse reactions were evaluated. The prognostic factors affecting the biochemical failure-free survival (BFFS) were analyzed.Results:The median follow-up time was 31 months. The 2- and 3-year overall survival (OS) rates were 100% and 96.9%, respectively. The 1-, 2-, and 3-year BFFS rates were 90%, 76.8% and 72%, respectively. The 1-, 2-, and 3-year distant metastasis-free survival (DMFS) rates were 92.2%, 82.8% and 75.1%, respectively. Gleason (GS) score ( χ2=10.00, P < 0.05) and adjacent tissue invasion ( χ2=8.85, P<0.05) were prognostic factors related to BFFS for LAPC. Adjacent tissue invasion and GS 9-10 were independent poor prognostic factors. The incidence of acute urinary adverse reaction and rectal injury (grade≥2) was 7.5% and 20%, respectively. The incidence of late urinary adverse reaction and rectal injury (grade≥2) was 12.5% and 17.5%, respectively. Adverse reactions at grade 3-4 did not occur. Conclusions:The moderately hypofractionated IMRT combined with ADT is feasible for LAPC treatment, achieving satisfactory survival effects. 70 Gy/25-28 f, 2.5-2.8 Gy/f is a safe and effective moderate hypofraction scheme. Adjacent tissue invasion and GS score are prognostic factors related to BFFS for LAPC.

Exposure to specific far-infrared ray based on gra-phene film promotes exercise capacity and glucose metabolism via AMPK / 中国药理学与毒理学杂志

OBJECTIVE AMPK activator,act as exer-cise mimetics,effective in preventing or ameliorating met-abolic diseases,including obesity and diabetes.Systemic activating of AMPK represents an important therapeutic strategy to treat metabolic diseases.However,whether far-infrared(FIR)hyperthermia therapy could be used as exercise mimetic to realize wide-ranging metabolic regu-lation,and its underling mechanisms remain unclear.METHODS The mice were subjected to hyperthermia in the FIR chamber(30±1)℃for 14 d.Exercise endurance was determined using a treadmill.Blood flow were mea-sured by the laser speckle contrast imaging.Combina-tion of microbiomic and metabolomic analysis,diversity of microbiota and metabolic profiling in muscle were detected.The microbiota disorder model via treatment with different cocktails of antibiotics(ABX).RESULTS The material characterization shows that the graphene synthesized by chemical vapour deposition(CVD)is dif-ferent from carbon fi ber,with single-layer structure and high electrothermal transform efficiency.The emission spectra generated by graphene-FIR device would maxi-mize matching those adsorbed by tissues(≈8.0 μm).Gra-phene-FIR improves core and epidermal temperature,and increases blood flow in femoral muscle and abdo-men.The diversity of gut microbiota was increased by graphene-FIR exposure.Graphene-FIR reduced the bac-teroidetes/firmicutes(B/F)ratio and increased the abun-dance of short-chain fatty acids(SCFA)-producing bac-teria,including Allobaculum,Blautia and Anaerostipes.Additionally,graphene-FIR stimulated the expression of SCFAs-sensing receptor(GPR 43),p-AMPK Thr172 and GLUT4,and increased the AMP/ATP ratio,thus enhanc-ing muscle glucose uptake.Metabolomic analyses revealed the significant changes in 25 metabolites,with twenty increased(eg.creatinine and phosphate)and five decreased(eg.lactic acid),and the marked impact of five metabolic pathways,including galactose metabo-lism,glycolysis,gluconeogenesis,fatty acid biosynthesis,butanoate metabolism,pyruvate metabolism.Further-more,a microbiota disorder model also demonstrates that the graphene-FIR effectively restore the exercise endurance with enhanced p-AMPK and GLUT4.CON-CLUSION Our results provide convincing evidence that graphene-based FIR therapy promoted exercise capacity and glucose metabolism via AMPK in gut-muscle axis.These novel insights into graphene-FIR therapy suggest a potential as an exercise mimetic for the treatment of metabolic disease in clinical.

Cannabinoid CB1 receptors are expressed in a sub-set of dopamine neurons and underlie cannabinoid modulation of DA release and DA-related behavior in mice / 中国药理学与毒理学杂志

OBJECTIVE Cannabinoids modulate do-pamine(DA)transmission and DA-related behavior,which has been thought to be mediated initially by acti-vation of cannabinoid CB1 receptors(CB1Rs)on GABA neurons.However,the cellular and receptor mechanisms underlying cannabinoids' psychoactive effects are not fully understood.The present study is to explore the pos-sible expression character of CB1Rs and elucidated the underlying mechanism of them.METHODS We took advantage of RNAscope in situ hybridization(ISH)assays and triple-staining assays to detect the CB1R-expressing neurons.We established an optical intracranial self-stimulation(OICSS)behavioral model by using opto-genetics to study dopaminergic reinforcement function.Natural and synthetic cannabinoids were used to study the function of CB1Rs.Conditional genetic depletion of CB1Rs and behavioral assay were performed to study the modulatory role of CB1Rs in DA-related behaviors.RESULTS We found that CB1Rs are also expressed in a subset of DA neurons and functionally underlie cannabi-noid action in male and female mice.ISH assays demon-strated CB1 mRNA in tyrosine hydroxylase(TH)-posi-tive DA neurons in the ventral tegmental area(VTA)and glutamate decarboxylase 1(GAD1)-positive GABA neu-rons.The CB1R expressing DA neurons were located mainly in the middle portion of the VTA with the number of CB1-TH colocalization progressively decreasing from the medial to the lateral VTA.Triple-staining assays indi-cated CB1R mRNA colocalization with both TH and vesicular glutamate transporter 2(VgluT2,a glutamate neuronal marker)in the medial VTA close to the midline of the brain.Optogenetic activation of this population of DA neurons was rewarding as assessed by OICSS.D9-tetrahydrocannabinol(D9-THC)or ACEA(a selective CB1R agonist)dose-dependently inhibited optical intra-cranial self-stimulation in DAT-Cre control mice,but not in conditional knockout mice with the CB1R gene absent in DA neurons.In addition,deletion of CB1Rs from DA neurons attenuated D9-THC-induced reduction in DA release in the NAc,locomotion,and anxiety.CONCLU-SION Our results indicated that CB1Rs are expressed in a subset of DA neurons that corelease DA and gluta-mate,and functionally underlie cannabinoid modulation of DA release and DA-related behavior.

Application of uterine artery blood flow ultrasonic parameters in prognosis evaluation of threatened abortion during early pregnancy / 中国基层医药

Objective:To explore the application value of uterine artery blood flow ultrasound parameters in evaluating the prognosis of threatened abortion during early pregnancy.Methods:In this non-randomized controlled prospective clinical study, 108 women with threatened abortion during early pregnancy (6-12 weeks of pregnancy) who received treatment in the Health Community Group of Yuhuan Second People's Hospital from July 2021 to December 2022 were included in the observation group. An additional 108 healthy women who were at the early stage of pregnancy were selected for the control group. Color Doppler ultrasound was performed in both groups to measure the ultrasonic parameters of uterine artery blood flow (peak systolic/end diastolic flow velocity, resistance index, pulsatility index) and compare their differences. The pregnant women in the observation group were followed up until 28 weeks of gestation, and their prognosis was analyzed. The pregnant women who had successfully insured their babies were included in the good prognosis group, and the pregnant women who had aborted their babies were included in the poor prognosis group. The ultrasonic parameters of uterine artery blood flow in the two groups were compared. Logistic regression analysis was used to analyze the correlation between ultrasound parameters of uterine artery blood flow and poor prognosis.Results:In the observation group, the systolic peak/end diastolic flow velocity, resistance index, and pulsatility index on the left side were (6.46 ± 1.71), (0.97 ± 0.30), (2.72 ± 0.89), respectively, and they were (6.49 ± 1.70), (0.96 ± 0.32), (2.70 ± 0.91) respectively on the right side, which were significantly greater than (3.90 ± 1.02), (0.64 ± 0.17), (1.36 ± 0.54), (3.91 ± 1.04), (0.62 ± 0.18), (1.35 ± 0.52) in the control group ( t = 13.36, 9.95, 13.58, 13.45, 9.62, 13.39, all P < 0.001). Twenty-eight-week follow-up results showed that 72 women (66.67%) in the observation group had successfully insured their babies and 36 women (33.33%) had aborted their babies. In the good prognosis group, the systolic peak/end diastolic flow velocity, resistance index, and pulsatile index were (7.95 ± 1.89), (1.22 ± 0.36), (3.06 ± 0.95) on the left side, and they were (7.45 ± 1.94), (1.24 ± 0.37), and (3.03 ± 0.96) on the right side, which were significantly greater than (4.72 ± 1.27), (0.77 ± 0.24), (1.74 ± 0.69), (4.74 ± 1.32), (0.75 ± 0.25), (1.77 ± 0.70) in the poor prognosis group ( t = 10.53, 7.73, 8.23, 8.55, 8.14, 7.76, all P < 0.001). Logistic regression analysis showed that peak systolic/end diastolic flow velocity and resistance index were risk factors for poor prognosis of threatened abortion during early pregnancy, while the pulsatility index had no significant correlation with poor prognosis of threatened abortion during early pregnancy. Conclusion:Uterine artery blood flow ultrasound parameters have a certain predictive value for the prognosis evaluation of threatened abortion during early pregnancy, which can provide an important reference for clinical fetal protection treatment and benefit the prognosis of pregnant women.

Analysis on the Current Status and Influencing Factors of Narrative Nursing Knowledge, Attitude, and Practice among Nurses in Grade A Tertiary Hospitals / 中国医学伦理学

【Objective:】 To understand the current status of narrative nursing knowledge, attitude, and practice (KAP) among nurses in grade A tertiary hospitals, and to provide a basis for the development of narrative nursing in relevant areas. 【Methods:】 Using convenience sampling methods, 931 nurses from three grade A tertiary hospitals in Xi’an were selected as subjects. A cross-sectional survey was conducted using the Clinical Nurses’ Narrative Nursing Knowledge and Trustworthiness Questionnaire and the General Self-Efficacy Scale. Multiple linear regression analysis was used to explore the influencing factors of nurses’ narrative nursing KAP. 【Results:】 The scores on the three dimensions of narrative nursing KAP were (23.70±2.99) points, (31.69±5.92) points, and (30.26±5.32) points, respectively. Nursing workload, general self-efficacy, professional title, and nursing satisfaction were the influencing factors of nurses’ narrative nursing knowledge dimension (P<0.05). There were statistically significant differences in nurses’ narrative nursing attitude dimension among nursing workload, general self-efficacy, professional title, monthly income, and nursing satisfaction (P<0.05). Nursing workload, general self-efficacy, nursing satisfaction, and accompanying experience were the influencing factors of nurses’ narrative nursing behavior dimension (P<0.05). 【Conclusion:】 Nurses in grade A tertiary hospitals have moderate narrative nursing knowledge, positive attitudes, and poor practice execution. The high nursing workload is the main barrier factor for the current development of narrative nursing. Nursing managers should actively build a diversified training system and guarantee system to boost the development of narrative nursing in clinical nursing work, and further promote the development of narrative nursing concepts.

Study on the Construction of a Doctor-patient Community from the Perspective of Struggle Spirit / 中国医学伦理学

Maintaining a harmonious doctor-patient relationship is an important foundation for the development of health care, and building a doctor-patient community is a key measure to maintain the harmonious doctor-patient relationship. To accelerate the construction of a doctor-patient community, it is necessary to establish a sense of struggle, grasp the connotation of a doctor-patient community, and understand its predicament, so as to propose targeted strategies for constructing a doctor-patient community. A doctor-patient community is a cooperative community, not a compromise community. The purpose of struggle is to better unite and cooperate. A doctor-patient community established under the guidance of struggle spirit is more united, more cohesive, and more effective. In the context of the new era, building a doctor-patient community faces the challenges of doctors being busy with "treatment" and neglecting emotional communication between doctors and patients, patients looking for "curing" and generating the illusion of omnipotence in medical skills, schools focusing on "medical skill" and weakening the cultivation of students’ humanities, the society lacking "integration" and disrupting the harmonious doctor-patient environment, etc. Building a doctor-patient community should strengthen emotional communication between doctors and patients, correct patients’ cognitive biases, enhance humanistic education, and create a good medical environment, with a view to promoting the healthy development of a doctor-patient community and facilitating the construction of the healthy China strategy.

Terpine-4-ol on inhibiting vascular smooth muscle cell calcification by improving mitochondrial dynamics / 药学学报

The aim of this study was to investigate the role and mechanism of terpinen-4-ol (T4O) on high glucose (HG) -induced calcification in vascular smooth muscle cell (VSMC). To investigate the role of T4O on HG-induced calcium deposition, osteogenic phenotypic transformation and mitochondrial dynamics in VSMC, Mdivi-1, a mitochondrial dynamin-related protein 1 (Drp-1) inhibitor, was used to analyze the correlation between mitochondrial dynamics and VSMC calcification and the role of T4O. Alizarin red S staining was used to observe calcium salt deposition and flow cytometry to detect intracellular Ca2+ content; Western blot and immunofluorescence were used to detect the expression of phenotypic switching-related markers α-smooth muscle actin (α-SMA), bone morphogenetic protein 2 (BMP2) and Runt related transcription factor 2 (Runx2), and mitochondrial dynamics-related markers mitofusin 1 (MFN1), mitofusin 2 (MFN2) and Drp-1. The results showed that low and high doses of T4O could inhibit HG-induced down-regulation of α-SMA, MFN1 and MFN2 expression levels, and up-regulation of BMP2, Runx2 and Drp-1 expression levels, reduce intracellular Ca2+ content and calcium salt deposition, and effectively inhibit HG-induced VSMC calcification and mitochondrial dynamics disorders. The T4O group, Mdivi-1 group and T4O+Mdivi-1 group were able to up-regulate the expression levels of HG-induced α-SMA, MFN1 and MFN2, down-regulate the protein expression levels of BMP2, Runx2 and Drp-1, and inhibit calcium salt deposition, and there was no significant difference between the above indexes in the T4O and T4O+Mdivi-1 groups. The above findings suggest that T4O can inhibit the expression level of Drp-1, regulate the disturbance of mitochondrial dynamics, and suppress HG-induced VSMC calcification.

ConclusionThis paper summarized nine items of telerehabilitation for patients with CHD, and analyzed the effects and related influencing factors of telerehabilitation on patients with CHD based on ICF.

Overexpression of miR-431-5p impairs mitochondrial function and induces apoptosis in gastric cancer cells via the Bax/Bcl-2/caspase3 pathway / 南方医科大学学报

OBJECTIVE@#To investigate the expression of microRNA miR-431-5p in gastric cancer (GC) tissues and its effects on apoptosis and mitochondrial function in GC cells.@*METHODS@#The expression level of miR-431-5p in 50 clinical samples of GC tissues and paired adjacent tissues was detected using real-time fluorescence quantitative PCR, and its correlation with the clinicopathological features of the patients was analyzed. A cultured human GC cell line (MKN-45 cells) were transfected with a miR-431-5p mimic or a negative control sequence, and the cell proliferation, apoptosis, mitochondrial number, mitochondrial potential, mitochondrial permeability transition pore (mPTP), reactive oxygen species (ROS) production and adenosine triphosphate (ATP) content were detected using CCK-8 assay, flow cytometry, fluorescent probe label, or ATP detection kit. The changes in the expression levels of the apoptotic proteins in the cells were detected with Western blotting.@*RESULTS@#The expression level of miR-431-5p was significantly lower in GC tissues than in the adjacent tissues (P < 0.001) and was significantly correlated with tumor differentiation (P=0.0227), T stage (P=0.0184), N stage (P=0.0005), TNM stage (P=0.0414) and vascular invasion (P=0.0107). In MKN-45 cells, overexpression of miR-431-5p obviously inhibited cell proliferation and induced cell apoptosis, causing also mitochondrial function impairment as shown by reduced mitochondrial number, lowered mitochondrial potential, increased mPTP opening, increased ROS production and reduced ATP content. Overexpression of miR-431-5p significantly downregulated the expression of Bcl-2 and increased the expressions of pro-apoptotic proteins p53, Bcl-2 and cleaved caspase-3 protein.@*CONCLUSION@#The expression of miR-431-5p is down-regulated in GC, which results in mitochondrial function impairment and promotes cell apoptosis by activating the Bax/Bcl-2/caspase3 signaling pathway, suggesting the potential role of miR-431-5p in targeted therapy for GC.

Genotype-environment interaction on arterial stiffness: A pedigree-based study / 北京大学学报(医学版)

OBJECTIVE@#To utilized the baseline data of the Beijing Fangshan Family Cohort Study, and to estimate whether the association between a healthy lifestyle and arterial stiffness might be modified by genetic effects.@*METHODS@#Probands and their relatives from 9 rural areas in Fangshan district, Beijing were included in this study. We developed a healthy lifestyle score based on five lifestyle behaviors: smoking, alcohol consumption, body mass index (BMI), dietary pattern, and physical activity. The measurements of arterial stiffness were brachial-ankle pulse wave velocity (baPWV) and ankle-brachial index (ABI). A variance component model was used to determine the heritability of arterial stiffness. Genotype-environment interaction effects were performed by the maximum likelihood methods. Subsequently, 45 candidate single nucleotide polymorphisms (SNPs) located in the glycolipid metabolism pathway were selected, and generalized estimated equations were used to assess the gene-environment interaction effects between particular genetic loci and healthy lifestyles.@*RESULTS@#A total of 6 302 study subjects across 3 225 pedigrees were enrolled in this study, with a mean age of 56.9 years and 45.1% male. Heritability of baPWV and ABI was 0.360 (95%CI: 0.302-0.418) and 0.243 (95%CI: 0.175-0.311), respectively. Significant genotype-healthy diet interaction on baPWV and genotype-BMI interaction on ABI were observed. Following the findings of genotype-environment interaction analysis, we further identified two SNPs located in ADAMTS9-AS2 and CDH13 might modify the association between healthy dietary pattern and arterial stiffness, indicating that adherence to a healthy dietary pattern might attenuate the genetic risk on arterial stiffness. Three SNPs in CDKAL1, ATP8B2 and SLC30A8 were shown to interact with BMI, implying that maintaining BMI within a healthy range might decrease the genetic risk of arterial stiffness.@*CONCLUSION@#The current study discovered that genotype-healthy dietary pattern and genotype-BMI interactions might affect the risk of arterial stiffness. Furthermore, we identified five genetic loci that might modify the relationship between healthy dietary pattern and BMI with arterial stiffness. Our findings suggested that a healthy lifestyle may reduce the genetic risk of arterial stiffness. This study has laid the groundwork for future research exploring mechanisms of arterial stiffness.

Feasibility of a single-port thoracoscopy-assisted five-step laparoscopic procedure via transabdominal diaphragmatic approach for No.111 lymphadenectomy in patients with Siewert type II esophageal gastric junction adenocarcinoma / 中华胃肠外科杂志

Objective: We aimed to explore the feasibility of a single-port thoracoscopy- assisted five-step laparoscopic procedure via transabdominal diaphragmatic(TD) approach(abbreviated as five-step maneuver) for No.111 lymphadenectomy in patients with Siewert type II esophageal gastric junction adenocarcinoma (AEG). Methods: This was a descriptive case series study. The inclusion criteria were as follows: (1) age 18-80 years; (2) diagnosis of Siewert type II AEG; (3) clinical tumor stage cT2-4aNanyM0; (4) meeting indications of the transthoracic single-port assisted laparoscopic five-step procedure incorporating lower mediastinal lymph node dissection via a TD approach; (5) Eastern Cooperative Oncology Group performance status (ECOG PS) 0-1; and (6) American Society of Anesthesiologists classification I, II, or III. The exclusion criteria included previous esophageal or gastric surgery, other cancers within the previous 5 years, pregnancy or lactation, and serious medical conditions. We retrospectively collected and analyzed the clinical data of 17 patients (age [mean ± SD], [63.6±11.9] years; and 12 men) who met the inclusion criteria in the Guangdong Provincial Hospital of Chinese Medicine from January 2022 to September 2022. No.111 lymphadenectomy was performed using five-step maneuver as follows: superior to the diaphragm, starting caudad to the pericardium, along the direction of the cardio-phrenic angle and ending at the upper part of the cardio-phrenic angle, right to the right pleura and left to the fibrous pericardium , completely exposing the cardio-phrenic angle. The primary outcome includes the numbers of harvested and of positive No.111 lymph nodes. Results: Seventeen patients (3 proximal gastrectomy and 14 total gastrectomy) had undergone the five-step maneuver including lower mediastinal lymphadenectomy without conversion to laparotomy or thoracotomy and all had achieved R0 resection with no perioperative deaths. The total operative time was (268.2±32.9) minutes, and the lower mediastinal lymph node dissection time was (34.0±6.0) minutes. The median estimated blood loss was 50 (20-350) ml. A median of 7 (2-17) mediastinal lymph nodes and 2(0-6) No. 111 lymph nodes were harvested. No. 111 lymph node metastasis was identified in 1 patient. The time to first flatus occurred 3 (2-4) days postoperatively and thoracic drainage was used for 7 (4-15) days. The median postoperative hospital stay was 9 (6-16) days. One patient had a chylous fistula that resolved with conservative treatment. No serious complications occurred in any patient. Conclusion: The single-port thoracoscopy-assisted five-step laparoscopic procedure via a TD approach can facilitate No. 111 lymphadenectomy with few complications.

Transcriptomic Effects of LINC01614 on Lung Cancer A549 Cells and Relevance of Drug Resistance / 肿瘤防治研究

Objective To investigate the biological role of LINC01614 in non-small cell lung cancer A549 cells and its drug resistance-related mechanism. Methods The CRISPR/Cas9 technology was used to construct the A549 cell model with knockdown of LINC01614. Transcriptome sequencing was performed on A549 cells knocked down with LINC01614. We validated the transcriptomic differential genes MCAM and ABCC3 at the gene level and MCAM at the protein level, detected the IC50 changes of A549 cells after knockdown of LINC01614 under the effect of different concentrations of cisplatin, and detected the effect of knockdown of LINC01614 on the migration ability of A549 cells. Results Of the 2 713 DEGs after knockdown of LINC01614, a total of 1 626 genes were up-regulated and 1, 087 genes were down-regulated. GO analysis showed that DEGs were associated with intracellular signaling, cell adhesion, and so on. Meanwhile, the KEGG analysis showed that DEGs were associated with the Wnt signaling pathway, TGF-β signaling pathway, and Rap1 signaling pathway. Selection of drug resistance-associated gene ABCC3 from DEGs for validation with MCAM: qRT-PCR results showed that knockdown of LINC01614 significantly down-regulated the expression of MCAM (P<0.05) and upregulated the expression of ABCC3 on A549 cells (P<0.05). After knockdown of LINC01614, the protein expression of MCAM, was significantly decreased in A549 cells (P<0.05); the IC50 of A549 cells to cisplatin was significantly increased (P<0.05); and the scratch healing rate of A549 cells was also significantly decreased (P<0.05). Conclusion LINC01614 may be associated with the proliferation, invasion, and apoptotic pathways of A549 cells. In addition, LINC01614 may exert its migration ability through MCAM and chemoresistance to cisplatin through ABCC3.

Meta analysis of the prevalence and influencing factors of WMSDs among dentists in China / 中华劳动卫生职业病杂志

Objective: To explore the relevant factors of work-related musculoskeletal disorders (WMSDs) among dentists through Meta analysis, providing a basis for the prevention and control of WMSDs among dentists. Methods: In April 2022, cross-sectional research literatures on the prevalence correlation of WMSDs among Chinese dentists were searched in databases such as China National Knowledge Infrastructure, Wanfang, VIP, PubMed, Web of Science, and Em Base database. The search was conducted from the establishment of the database until April 2022, literatures were selected using keywords such as musculoskeletal disorders and dentists. To extract gender, age, length of service, disease classification and other related influencing factors as indicator, and prevalence was selected as the outcome indicator. After evaluating the quality of the literatures, RevMan 5.3 software was used to calculate the combined RD (95%CI) values of the included literatures. Results: A total of 15 articles were included, with a total sample size of 3646 people. Meta analysis results showed that the prevalence of WMSDs among dentists in China was 80%, and the top three parts of the incidence rates were 65% of the waist, 58% of the neck, and 50% of the back. Gender, age, length of service, region and disease classification all increased the risk of WMSDs, and the combined effect size were 75%, 78%, 71%, 77% and 82% respectively (P<0.05) . Conclusion: The occurrence of WMSDs among dentists in China is related to multiple factors such as gender, age, length of service and disease classification. The above risk factors should be taken into account in the workplace and preventive measures should be actively implemented to prolong the working life of dentists.
