Tuberculosis (TB) is an infectious disease caused by Mycobacterium tuberculosis complex and is mainly manifested as pulmonary tuberculosis. Mycobacterium tuberculosis is characterized by high pathogenicity and drug resistance due to its high viability and lethality, and multidrug-resistant tuberculosis caused by it has become a global public health problem. Early and effective treatment is essential to prevent the emergence of drug-resistant strains. Commonly employed methods for the screening and diagnosis of TB include: clinical signs, imaging examinations (chest X-ray, computed tomography), sputum culture (L-J medium, BACTEC liquid culture system), and immunological tests (lipoarabinomannan antigen test, tuberculin skin test, interferon-gamma release test). In recent years, emerging molecular diagnostic methods such as GeneXpert MTB/RIF assay, loop-mediated isothermal amplification (LAMP), linear probe assay, and whole-genome sequencing have been used to diagnose and characterize TB. These methods not only identify Mycobacterium tuberculosis but also detect mutation sites associated with resistance to first-line anti-tuberculosis drugs (isoniazid, rifampicin, etc.), providing new possibilities for the diagnosis of drug-resistant Mycobacterium tuberculosis. In this paper, the advantages and disadvantages of some commonly used detection methods for tuberculosis are first reviewed, aiming at assisting clinicians to diagnose and treat the disease in a timely manner. Secondly, this paper explores the prospects of the latest high-throughput detection methods for drug-resistant Mycobacterium tuberculosis.

miR-135 is a highly conserved miRNA in mammals and includes miR-135a and miR-135b.Recent studies have shown that miR-135b is a key regulatory factor in cardio-cerebrovascular diseases.It is involved in regulating the pathological process of myocardial infarction,myocardial ischemia/reperfusion injury,cardiac hypertrophy,atrial fibrillation,diabetic cardiomyopathy,atherosclerosis,pulmonary hyperten-sion,cerebral ischemia/reperfusion injury,Parkinson's disease,and Alzheimer's disease.Obviously,miR-135b is an emerging player in cardio-cerebrovascular diseases and is expected to be an important target for the treatment of cardio-cerebrovascular diseases.However,the crucial role of miR-135b in cardio-cerebrovascular diseases and its underlying mechanism of action has not been reviewed.Therefore,in this review,we aimed to comprehensively summarize the role of miR-135b and the signaling pathway mediated by miR-135b in cardio-cerebrovascular diseases.Drugs targeting miR-135b for the treatment of diseases and related patents,highlighting the importance of this target and its utility as a therapeutic target for cardio-cerebrovascular diseases,have been discussed.

Objective:To explore the relationship between white matter integrity and cognitive function in first-episode children and adolescents with schizophrenia by diffusion tensor imaging (DTI).Methods:Totally 84 children and adolescents with first-episode schizophrenia who were hospitalized in the Department of Child and Adolescent Psychiatry at the Second Affiliated Hospital of Xinxiang Medical University from September 2017 to June 2021 were selected as the study group, and 35 healthy children and adolescents matched with the study group were selected as the control group. Positive and negative symptom scale (PANSS) was used to assess the patient's mental symptoms. Diffusion tensor imaging (DTI) scans were performed, and the structural integrity of white matter fibers in the brain was measured by tract-based spatial statistics (TBSS), with the indicators including fractional anisotropy (FA). The Chinese version of measurement and treatment research to improve cognition in schizophrenia consensus cognitive battery (MCCB) and the Stroop color-word test were used to evaluate the cognitive function of all subjects. SPSS 26.0 software was used to analyse the data by analysis of variance, independent sample t-test, Mann Whitney U-test and Pearson correlation analysis. Results:(1)The FA values of the right superior longitudinal tract (MNI: x=49, y=-40, z=31) and the left corticospinal tract (MNI: x=-27, y=-22, z=-19) in the study group were higher than those in the control group(both P<0.05). The FA values of the bilateral cingulate gyrus (MNI: x=-7, y=25, z=14; x=20, y=-50, z=25) and the occipital part of the corpus callosum radiation line (MNI: x=-19, y=-50, z=21) in the study group were lower than those in the control group(both P<0.05).(2)The trail making test score of the study group was higher than that of the control group( t=4.344, P<0.01), and the scores of the symbol coding, Hopkins verbal learning test-revised( HVLT-R), brief visuospatial memory test-revised(BVMT-R), word fluency test, number span, maze, Stroop word, Stroop color and Stroop color words were lower than those in the control group( t=-13.041--3.204, all P<0.05). (3) The FA value of right cingulate gyrus (hippocampus) was negatively correlated with the number span ( r=-0.269, P=0.023).The FA value in occipital part of the corpus callosum radiation line was positively correlated with the symbol code ( r=0.237, P=0.047).The FA value of the left lower longitudinal bundle was negatively correlated with the Stroop color and maze ( r=-0.289, -0.275; P=0.010, 0.020).The FA value of the right inferior longitudinal fasciculus was negatively correlated with the score of maze ( r=-0.254, P=0.032). The FA value of occipital part of the corpus callosum radiation line was positively correlated with positive symptom score ( r=0.170, P=0.040). Conclusion:Cognitive dysfunction in children and adolescent with first-episode schizophrenia may be related to abnormal white matter integrity in the brain.

ObjectiveTo evaluate the effect of Huatan Tongluo prescription on the vulnerability of atherosclerotic plaques in the carotid arteries of patients with hypertension of phlegm-stasis combination syndrome. MethodA total of 132 eligible patients were randomly divided into an observation group （66 cases） and a control group （66 cases）. The control group received oral atorvastatin calcium tablets and enteric-coated aspirin tablets， while the observation group received Huatan Tongluo prescription in addition to the treatment received by the control group. The treatment duration was 6 months. A carotid artery ultrasound examination was performed to record the number of plaques， the maximum plaque area， the maximum plaque cross-sectional thickness， and the intima-media thickness （IMT） of the carotid artery. Crouse score， plaque vulnerability score， and phlegm-stasis combination syndrome score were assessed. Blood lipid levels ［total cholesterol （TC）， triglyceride （TG）， high-density lipoprotein cholesterol （HDL-C）， and low-density lipoprotein cholesterol （LDL-C）］， inflammatory markers ［neutrophil-to-lymphocyte ratio （NLR）， monocyte-to-lymphocyte ratio （MLR）， interleukin-6 （IL-6）， and high-sensitivity C-reactive protein （hs-CRP）］， vascular endothelial function ［endothelin-1 （ET-1）， von Willebrand factor （vWF）， and nitric oxide （NO）］， and relevant proteins ［pentraxin 3 （PTX3） and galectin-3 （Gal-3）］ levels were measured. Safety evaluation was conducted， and comparisons were made in terms of carotid artery stenosis rate， plaque regression efficacy， and traditional Chinese medicine （TCM） syndrome efficacy. ResultCompared with the results before treatment， both groups showed significant reductions in IMT， plaque number， maximum plaque area， and maximum plaque cross-sectional thickness （P<0.05）. After treatment， the observation group exhibited more significant reductions in the above indicators compared with the control group （P<0.05）. After treatment， Crouse scores， plaque vulnerability scores， and phlegm-stasis combination syndrome scores in both groups were lower than those before treatment （P<0.05）. After treatment， the observation group had lower scores in these indicators than the control group （P<0.05）. In terms of blood lipid levels， both groups showed decreases in TC， TG， and LDL-C levels， and an increase in HDL-C levels after treatment compared to those before treatment （P<0.05）. The observation group exhibited greater improvements in these lipid parameters than the control group （P<0.05）. Inflammatory markers NLR， MLR， IL-6， and hs-CRP significantly decreased in both groups after treatment compared with those before treatment （P<0.05）. The observation group showed more significant reductions in these markers than the control group after treatment （P<0.05）. After treatment， both groups demonstrated decreases in levels of ET-1， vWF， PTX3， and Gal-3， along with an increase in NO levels compared with those before treatment （P<0.05）. The observation group showed more significant improvements in these markers than the control group after treatment （P<0.05）. After treatment， the observation group had a lower carotid artery stenosis rate than the control group （P<0.05）. The plaque regression efficacy rate was 51.72% （30/58） in the observation group， and the total effective rate of TCM syndrome was 84.48% （49/58）， both of which were higher than 18.64% （11/59） and 52.54% （31/59） in the control group （χ²=10.061， 13.799， P<0.05）. No adverse reactions related to the Huatan Tongluo prescription were observed during the treatment period. ConclusionIn addition to statin therapy， Huatan Tongluo prescription can effectively reverse carotid artery atherosclerotic plaques in patients with hypertension and carotid artery stenosis， reduce plaque vulnerability， exhibit lipid-lowering and anti-inflammatory effects， and improve vascular endothelial function. The treatment demonstrates favorable clinical efficacy and safety. Therefore， it is very worthy of clinical promotion and application.

Background: Excessive delivery of free fatty acids (FFAs) to the liver promotes steatosis and insulin resistance (IR), with IR defined as reduced glucose uptake, glycogen synthesis and anti-lipolysis stimulated by normal insulin levels. Whether the associations between FFAs and diabetes development differ between patients with and without nonalcoholic fatty liver disease (NAFLD) remains unclear. Methods: Consecutive subjects (2,220 NAFLD subjects and 1,790 non-NAFLD subjects according to ultrasound imaging) were enrolled from the First Affiliated Hospital of Sun Yat-sen University between 2009 and 2019. The homeostasis model assessment of insulin resistance (HOMA-IR) was calculated. Results: There was an approximate J-shaped relationship between FFA levels and HOMA-IR in the NAFLD group. Higher FFA concentration quartiles were associated with higher risks of IR (odds ratio [OR], 9.24; 95% confidence interval [CI], 6.43 to 13.36), prediabetes (OR, 10.48; 95% CI, 5.66 to 19.39), and type 2 diabetes mellitus (T2DM; OR, 19.43; 95% CI, 12.75 to 29.81) in the NAFLD group but not in the non-NAFLD group. The cut-off points for the FFA levels increased in a stepwise manner in discriminating IR, prediabetes and T2DM (573, 697, and 715 μmol/L) in the NAFLD group but not in non-NAFLD individuals. Conclusion A distinct dose-dependent relationship of FFA levels was found with IR, prediabetes and T2DM in NAFLD patients. Screening serum FFA levels in NAFLD patients would be valuable in preventing diabetes development.

Objective:To explore the effect of attribution training on cancer-related fatigue, quality of life and psychological state of patients after lung cancer surgery.Methods:From July 2019 to July 2020, convenience sampling was used to select 89 postoperative patients with lung cancer who were admitted to Peking Union Medical College Hospital. Patients were divided into the control group ( n=44) and the observation group ( n=45) with random number table method. The control group conducted routine nursing, and the observation group carried out attribution training on the basis of the control group. The general information of the two groups of patients was collected, and the Cancer Fatigue Scale (CFS) , WHO Quality of Life Scale-100 (WHOQOL-100) and Hospital Anxiety and Depression Scale (HADS) scores were compared between the two groups. Results:The WHOQOL-100 scores of the observation group were higher than those of the control group at one and three months after the intervention, and the differences were statistically significant ( P<0.05) . After the intervention, the CFS scores of the two groups of patients were lower than those before the intervention, and the CFS scores of the observation group was lower than that of the control group, and the differences were statistically significant ( P<0.05) . The HADS scores of the observation group were lower than those of the control group at one and three months after the intervention, and the differences were statistically significant ( P<0.05) . Conclusions:Attribution training can effectively improve the cancer-related fatigue, anxiety and depression in patients with lung cancer, and improve the quality of life of patients. It is worthy of clinical promotion.

Objective:To investigate the relationships of rs4658971 polymorphism of disrupted-in-schizophrinia-1 ( DISC1) gene with schizophrenia in children and adolescents and with the brain structure of such patients. Methods:(1) A total of 577 children and adolescents with schizophrenia were recruited from the Inpatient Department of the Second Affiliated Hospital of Xinxiang Medical University from October 2010 to December 2018, and 516 healthy children were selected as the control group.The rs4658971 polymorphism of DISC1 gene was detected by restriction fragment length polymorphism (PCR-RFLP). The differences of DISC1 genotype and allele frequencies between schizophrenia patients and healthy children were compared by Chi-square test.(2)One hundred and eighteen patients with the first-episode schizophrenia whose illness duration was no more than 12 months and 101 healthy children and adolescents were detected by 3.0T magnetic resonance imaging (MRI). The craniocerebral structures of patients with different DISC1 genotypes were analyzed by covariance with age as the covariant. Results:(1) The rs4658971 genotype frequencies(TT 6.6% vs.5.2%, TC 37.4% vs.38.4%, CC 56.0% vs.56.4%, χ2=0.91, P=0.63) and allele frequencies(C 74.70% vs.75.58%, T 25.30% vs.24.42%, χ2=0.23, P=0.63) of DISC1 gene in children and adolescents with schizophrenia were not significantly different from those in the healthy children.(2) Compared with the control group, the transverse diameter of the third ventricle was significantly enlarged in children and adolescent with schizophrenia [(4.68±1.41) mm vs.(4.06±1.36) mm, F=8.534, P=0.004], while the distance between the anterior feet of the lateral ventricle, the width of the caudate nucleus head and the thickness of the hippocampus were significantly reduced [(30.69±2.51) mm vs.(32.02±2.41) mm, (8.17±1.01) mm vs.(9.22±1.14) mm, (8.93±0.97) mm vs.(9.93±1.14) mm], and the differences were statistically significant( F=15.435, 40.201, 44.650, all P<0.001). The covariance analysis (with age as the covariant) showed that there was significant difference in the width of the caudate nucleus head between patients with CC genotype and those with CT+ TT genotype[(8.73±0.85) mm vs.(7.39±0.61) mm, F=41.376, P<0.001]. Conclusions:There are multiple brain structural changes in children and adolescents with first-episode schizophrenia.T allele carriers of DISC1 gene rs4658971 locus may be related to the reduced width of the caudate nucleus head in patients.

Objective:To evaluate the effect of interstitial lung disease(ILD) on postoperative morbidity and mortality in pulmonary resection for lung cancer patients.Methods:We retrospectively analyzed 971 patients undergoing pulmonary operation from January 2010 to January 2018 in our hospital. Clinical data including age, sex, history of chronic obstructive pulmonary disease(COPD), smoking history, smoking index, American Society of Anesthesiologists(ASA) classification, forced expiratory volume in 1 s(FEV1) % predict, surgical procedure, video assisted thoracoscopic surgery(VATS) or not, intraoperative blood transfusion, anesthesia time, operation time/one-lung ventilation time, blood loss, histology, postoperative morbidity, 60-days mortality, onset of acute exacerbation of interstitial lung disease(AE-ILD), drainage, extubation time, and postoperative stay were collected and analyzed.Results:There were 80(8.2%) and 891(91.8%) patients in ILD and non-ILD group, respectively. AE-ILD occurred in 5 patients, with a 60-day mortality of 80%. A multivariate regression analysis identified that the sex( P=0.023), ILD( P=0.001), COPD( P=0.027) were independent risk factors for postoperative morbidity. ILD( P=0.023) and postoperative morbidity( P=0.001) were independent risk factors for 60-day mortality in multivariate analysis. Conclusion:Patients with ILD had a higher incidence of postoperative morbidity and 60-day mortality. Based on the obvious postoperative morbidity and mortality, special attention and management should be taken in ILD patients.
