RESUMO
Anti-tuberculosis drug-induced liver injury(ATB-DILI) is the most common adverse reaction during anti-tuberculosis therapy in tuberculosis patients. At present, the diagnosis of ATB-DILI is mainly based on traditional biomarkers such as transaminases, but these indicators have low specificity for liver toxicity, they cannot explain the mechanism of liver injury and the early onset of ATB-DILI. Based on the prediction of disease severity, treatment and prevention, this paper described the current potential biomarkers of ATB-DILI.

A series of studies on the interventional diagnosis and treatment of tuberculosis(TB)were carried out by domestic and foreign researchers in 2023. The combination of minimally invasive interventional procedures with endoscopes, guidance, material acquisition techniques by multiple ways and multichannel and highly accurate laboratory testing techniques is becoming more and more widely practiced clinically, which has played an important role in the accurate diagnosis of problematic TB. Diagnostic procedures for pulmonary TB, tracheobronchial TB, mediastinal lymphatic TB and extrapulmonary TB included conventional flexible bronchoscopy and specific types of bronchoscopy(ultrathin bronchoscopy and endobronchial ultrasound), transbronchial needle aspiration biopsy, endobronchial ultrasound and virtual bronchoscopic navigation system-guided forceps biopsy, thoracoscopic cryobiopsy of pleura, percutaneous biopsy, and so on. The time to diagnosis has been significantly reduced and the diagnostic efficacy has been improved by the clinical specimen detection using either Gene Xpert MTB/RIF, Ultra, loop-mediated isothermal amplification, metagenomic next-generation sequencing, or nanopore sequencing, etc. Interventional therapy was focused on the following diseases: pulmonary TB with massive hemoptysis, tracheobronchial TB, pleural TB and TB-related fistulas. Interventional treatment of tracheobronchial TB mainly included the application of rigid bronchoscopy, bronchoscopic cold and thermal ablation treatment, endoscopic clamp, dilatations of narrow airway with balloon and stent placement, etc. The interventional treatment of pulmonary TB complicated by massive hemoptysis included endovascular embolization, coated stent placement, etc. Interventional treatment of pleural TB involved the application of thoracoscopy, endoscopic forceps, the implantation of stent and other occlusive devices and the closure of fistulas with autologous fat transplantation. In this article, we reviewed the progress of interventional diagnosis and treatment of TB by the search of published literatures from October 2022 to September 2023.

OBJECTIVE: Endometriosis is a common gynecological disease, affecting 5 to 10% of women of childbearing age. We analyzed pregnancy complications and neonatal outcomes of patients with pregnancies complicated with endometriosis. The aim of the study was to explore the effects of endometriosis on pregnancy and to evaluate the potential pregnancy risks associated with this disease. PATIENTS AND METHODS: The retrospective study included 3,809 parturients who were routinely examined, hospitalized and underwent cesarean section delivery in Fujian Maternal and Child Health Hospital from January 2014 to December 2020. Among them, 1,026 parturients were diagnosed with endometriosis after the cesarean section (endometriosis group), and 2,783 parturients without endometriosis comprised the control group. The endometriosis group was further divided into subgroups according to the severity of the disease: 882 parturients with stage â or â ¡ of endometriosis, and 144 parturients with stage â ¢ or â £ of endometriosis. General data of all patients and medical records of pregnancy complications and neonatal outcomes for each group were collected and retrospectively analyzed. RESULTS: There were no statistically significant differences in the age, gestational age, gestation, and parity times between all groups (p>0.05). The incidence of preeclampsia and placenta previa in the endometriosis group was higher than that in the control group (p<0.05). There was no significant difference in rates of other pregnancy complications, such as chronic hypertension with pregnancy, preeclampsia with chronic hypertension, hemolysis, elevated liver enzymes and low platelets (HELLP) syndrome, gestational diabetes mellitus (GDM), pregestational diabetes mellitus (PGDM), intrahepatic cholestasis of pregnancy (ICP), premature rupture of membranes or placental abruption between the two groups. The incidence of placenta previa in the group of patients with stage III/IV endometriosis was higher than in patients with stage I/II endometriosis (p<0.05). However, there was no significant difference in the incidence of other pregnancy complications. The amount of postpartum hemorrhage (1,000-1,500 ml) in the endometriosis group was greater than that in the control group, and the difference was statistically significant (p<0.05). However, there was no significant difference in the incidence of postpartum hemorrhage in patients with pregnancies complicated with endometriosis at different stages. CONCLUSIONS: In pregnant women, endometriosis is associated with an increased incidence of placenta previa that correlates with the severity of the disease. Pregnant women with endometriosis have higher rates of preeclampsia and postpartum hemorrhage, compared to women without endometriosis.

Objective: To investigate the risk factors for pulmonary atelectasis in adults with tracheobronchial tuberculosis(TBTB). Methods: Clinical data of adult patients (≥18 years old) with TBTB from February 2018 to December 2021 in Public Health Clinical Center of Chengdu were retrospectively analyzed. A total of 258 patients were included, with a male to female ratio of 1â¶1.43. The median age was 31(24, 48) years. Clinical data including clinical characteristics, previous misdiagnoses/missed diagnoses before admission, pulmonary atelectasis, the time from symptom onset to atelectasis and bronchoscopy, bronchoscopy and interventional treatment were collected according to the inclusion and exclusion criteria. Patients were divided into two groups according to whether they had pulmonary atelectasis. Differences between the two groups were compared. Binary logistic regression was used to analyze the risk factors for pulmonary atelectasis. Results: The prevalence of pulmonary atelectasis was 14.7%, which was most common in the left upper lobe (26.3%). The median time from symptom onset to atelectasis was 130.50(29.75,358.50)d, and the median time from atelectasis to bronchoscopy was 5(3,7)d. The median age, the proportion of misdiagnosis of TBTB before admission, and the time from symptom onset to bronchoscopy in the atelectasis group were higher than those without atelectasis, and the proportion of receiving bronchoscopy examination and interventional therapy previously, and the proportion of pulmonary cavities were lower than those without atelectasis (all P<0.05). The proportions of cicatrices stricture type and lumen occlusion type in the atelectasis group were higher than those without atelectasis, while the proportions of inflammatory infiltration type and ulceration necrosis type were lower than those without atelectasis (all P<0.05). Older age (OR=1.036, 95%CI: 1.012-1.061), previous misdiagnosis(OR=2.759, 95%CI: 1.100-6.922), longer time from symptom onset to bronchoscopy examination (OR=1.002, 95%CI: 1.000-1.005) and cicatrices stricture type (OR=2.989, 95%CI: 1.279-6.985) were independent risk factors for pulmonary atelectasis in adults with TBTB (all P<0.05). Of the patients with atelectasis who underwent bronchoscopy interventional therapy, 86.7% had lung reexpansion or partial reexpansion. Conclusions: The prevalence of pulmonary atelectasis is 14.7% in adult patients with TBTB. The most common site of atelectasis is left upper lobe. The TBTB type of lumen occlusion is complicated by pulmonary atelectasis in 100% of cases. Being older, misdiagnosed as other diseases, longer time from onset of symptoms to bronchoscopy examination, and being the cicatrices stricture type are factors for developing pulmonary atelectasis. Early diagnosis and treatment are needed to reduce the incidence of pulmonary atelectasis and increase the rate of pulmonary reexpansion.

With the emergence of new tuberculosis patients, the number of patients with tuberculosis sequelae is increasing, which not only increases the medical burden of tuberculosis sequelae year by year, but also affects the health-related quality of life (HRQOL) of patients. The HRQOL of patients with tuberculosis sequelae has gradually received attention, but there are few relevant studies. Studies have shown that HRQOL is related to various factors such as post-tuberculosis lung disease, adverse reaction to anti-tuberculosis drugs, decreased physical activity, psychological barriers, low economic status and marital status. This article reviewed the current situation of HRQOL in patients with sequelae of tuberculosis and its influencing factors, in order to provide a reference for improving the quality of life of patients with sequelae of tuberculosis.

Objective: To summarize the characteristics of patients with newly diagnosed multiple myeloma (NDMM) admitted at Ruijin Hospital affiliated to Shanghai Jiaotong University School of Medicine. We compared the clinical characteristics and prognoses among patients with non-extramedullary disease (EMD), bone-related extramedullary (EM-B) disease, and extraosseous extramedullary (EM-E) disease and further explored the effects of autologous hematopoietic stem cell transplantation (ASCT) for EMD. Methods: From January 2015 to January 2022, data of 114 patients (22%) with EMD out of 515 patients with NDMM were retrospectively analyzed; 91 (18%) and 23 (4%) patients comprised the EM-B and EM-E groups, respectively. The clinical characteristics of patients in all groups were compared with the Chi-square test. Progression-free survival (PFS) and overall survival (OS) of patients were analyzed by the Kaplan-Meier method. Independent prognostic factors were determined using multivariate Cox proportional hazard model. Results: There were no significant differences in age, gender, ISS stage, light chain, creatinine clearance, cytogenetic risk, 17p deletion, ASCT, and induction regimens among the three groups. Overall, 13% of EM-E patients had IgD-type M protein, which was significantly higher than that in EM-B patients (P=0.021). The median PFS of patients in the non-EMD, EM-B, and EM-E groups was 27.4, 23.1, and 14.0 months; the median OS was not reached, 76.8 months, and 25.6 months, respectively. The PFS (vs non-EMD, P=0.004; vs EM-B, P=0.036) and OS (vs non-EMD, P<0.001; vs EM-B, P=0.002) were significantly worse in patients with EM-E, while those were not significantly different between patients with EM-B and those with non-EMD. In the multivariate analysis, EM-E was an independent prognostic factor for OS in patients with NDMM (HR=8.779, P<0.001) and negatively impacted PFS (HR=1.874, P=0.050). In those who did not undergo ASCT, patients with EM-B had significantly worse OS than those with non-EMD (median 76.8 months vs. not reached, P=0.029). However, no significant difference was observed in the PFS and OS of patients with EM-B and those with non-EMD who underwent ASCT. Conclusions: Compared to patients with either non-EMD or EM-B, those with EM-E had the worst prognosis. EM-E was an independent risk factor for OS in patients with NDMM. ASCT can overcome the poor prognosis of EM-B.

Objective: To investigate the molecular regulatory mechanism of Mycobacterium tuberculosis (MTB) protein Rv0309 to promote the survival of Mycobacterium smegmatis (Ms) in macrophages. Methods: Using Ms as a model to study Mycobacterium tuberculosis, recombinant Ms transfected with pMV261 and PMV261-RV0309 in the control group and RAW264.7 cells were constructed. The effect of Rv0309 protein on intracellular survival of Ms was investigated by counting colony forming units (CFUs). Mass spectrometry was used to screen proteins interacting with host protein Rv0309, and immunocoprecipitate (Co-IP) was used to verify that host protein STUB1 could interact with host protein Rv0309. STUB1 gene knock-out RAW264.7 cells were infected with Ms, and CFUs were counted to explore the effect of protein Rv0309 on intracellular survival of Ms after STUB1 gene knock-out. STUB1 gene knock-out RAW264.7 cells were infected with Ms, and after obtaining samples, Western blotting assay was performed to explore the effect of protein Rv0309 on autophagy function of macrophages after STUB1 gene knock-out. Statistical analysis was performed using GraphPad Prism 8 software. T-test was selected for analysis in this experiment, with P<0.05 was considered statistically significant. Results: Western blotting showed that Rv0309 was expressed in M. smegmatis and secreted extracellularly. The CFUs of the Ms-Rv0309 group was higher than that of Ms-pMV261 group at 24 h after THP-1 macrophage infection, and the difference was statistically significant (P<0.05). The trend of infected RAW264.7 macrophages was the same as that of infected THP-1 macrophages. The Co-IP results showed that the corresponding Flag and HA bands appeared in the results of immunoprecipitation (IP):Flag and IP: HA. The level of CFUs in the experimental group with STUB1 deletion was significantly higher than that in the control group without STUB1 deletion. Compared with Ms-pMV261, the CFUs in the Ms-Rv0309 group was significantly higher than that in the Ms-pMV261 group. The gray scale of LC3â ¡ bands of Ms-Rv0309 in experimental group was lighter than that of Ms-pMV261 in the control group at the corresponding time point, and the result was most significant at 8 h (LC3â ¡/ß-actin: 0.76±0.05 vs 0.47±0.07), the difference being statistically significant (P<0.05). After STUB1 genome knock-out, the gray level of LC3â ¡ bands at the corresponding time was lighter than that without STUB1 genome knock-out. Comparison of the results of Ms-pMV261 and Ms-Rv0309 strains revealed that LC3â ¡ band gray Rv0309 group was lighter at the corresponding time compared with pMV261 group. Conclusions: MTB protein Rv0309 can be successfully expressed in M. smegmatis and secreted extracellularly, which can inhibit the autophagy process of macrophages. Protein Rv0309 interacts with host protein STUB1 to inhibit macrophage autophagy and promote intracellular survival of Ms.

Tuberculosis (TB) continues to be a global public health issue that threatens human health, and rapid and accurate pathogen detection is the key to early diagnosis and effective treatment. In recent years, the pathogenic diagnosis of tuberculosis is expanding from traditional bacteriological diagnosis to molecular diagnosis. In the past year, Xper MTB/RIF Ultra technology with good diagnostic performance has been applied more often to the detection of non-respiratory samples, and Xpert XDR and second-generation linear probe technology provided more basis for early and accurate diagnosis of multidrug resistance; genome sequencing technology has also been developed and applied more often to the detection of non-culture sample detection, and the cost and time required for detection have been relatively reduced. Truenat technology, which is more suitable for primary care centers, is more widely used; new TB detection technologies, such as cell-free DNA testing and mass spectrometry, are also being developed and are expected to become important tools for early and rapid diagnosis of TB and drug-resistant TB. In this review, we synthesized the major research results of molecular biology diagnosis of tuberculosis around the world from 1st October 2021 to 30th September 2022, and comprehensively evaluated the advantages, disadvantages and current application of molecular biology detection technologies to provide a significant basis for clinical decision-making.

Using low-energy electron diffraction and angle-resolved photoemission spectroscopy, we investigated the lattice and electronic structures of the Pb(111) surface upon the adsorption of Au atoms at the low temperature T = 40 K. Unlike earlier results showing the formation of PbAu-alloy layers at room temperature, we found that Au atoms form a ultra-thin superstructure, Au/Pb(111)-3 × 3, on top of the Pb(111) surface. Moreover, three surface-state bands, S1, S2, and S3, are induced within and immediately adjacent to the Pb bulk projected band gap centered at the surface zone boundary [Formula: see text] at the energies of - 0.02, - 1.05, and - 2.56 eV, respectively. First-principles calculation based on Au/Pb(111)-3 × 3 confirms the measured surface-state bands among which the most interesting are the S1 and S3 surface states. They are derived from surface resonances in Pb(111). Moreover, S1, which disperses across Fermi level, exhibits a large anisotropic Rashba splitting with α of 1.0 and 3.54 eVÅ in the two symmetry directions centered at [Formula: see text]. The corresponding Rashba splitting of S1 band in Cu/Pb(111)-3 × 3 and Ag/Pb(111)-3 × 3 were calculated for comparison.
RESUMO
At present, the number of cases with multidrug/rifampicin-resistant tuberculosis (MDR/RR-TB) in China ranks fourth in the world, and the prevention and control situation is still serious. Chemotherapy, as the most important treatment for MDR/RR-TB, was studied and explored by domestic and foreign researchers in 2022. New chemotherapeutic drugs such as delpazolid, sutezolid, telacebec and independently developed anti-tuberculosis drugs such as pyrifazimine, sudapyridine and JBD0131 are still in clinical trials. The efficacy, safety, tolerability, adverse reactions and drug resistance of bedaquiline, linezolid, delamanid and pretomanid have been studied extensively. Meanwhile, different new chemotherapy regimens centered on new drugs have been explored in-depth by international scholars. In this article, we reviewed the progress of chemotherapy of multidrug/rifampicin-resistant tuberculosis from October 2021 to September.

OBJECTIVE: Primary central nervous system (CNS) cancer is a predominant source of mortality and morbidity globally. This study aims to analyze the burden and variation trends of CNS cancer in China from 1990 to 2019. MATERIALS AND METHODS: In this cross-sectional study, we analyzed people of all ages with CNS cancer in China from January 1, 1990, to December 31, 2019. We collected the data including incidence, deaths, and disability-adjusted life-years (DALYs) from the Global Burden of Disease (GBD) study 2019. The age-standardized incidence rate (ASIR), age-standardized death rate (ASDR), and DALYs rate were compared by age and sex. RESULTS: In 2019, there were more than 94 (95% uncertainty intervals [CI]: 73-114) thousand incident cases, 63 (47-76) thousand deaths and 2.0 (1.5-2.5) million DALYs due to CNS cancer in China in 2019. From 1990 to 2019, the absolute number of incident cases, deaths, and DALYs increased by 107.0% (39.0 to 169.0), 67.0% (12.0 to 117.0), and 16.0% (-23.0 to 63.0). The ASIR increased by 28.0% (-16.0 to 64.0). ASDR and age-standardized DALYs rate decreased by -10.0% (-40.0 to 15.0) and -22.0% (-50.0 to 10.0), respectively. CONCLUSIONS: The overall burden due to CNS cancer in China remains high, as evidenced by the sharp increase in the incident cases, deaths, and DALYs from 1990 to 2019. Elderly patients and neonates show relatively high burden. Sex-specific differences in the incidence of CNS cancer in China are observed.

BACKGROUND: Metabolic syndrome (MetS) is a complex of interrelated risk factors, including central adiposity, increased blood pressure, hyperglycemia, elevated triglyceride levels and low high-density lipoprotein. Few studies have reported the genetic variants in the Sirt1 and Nrf2 genes (Sirt1 rs7895833 A > G, Sirt1 rs2273773 C > T and Nrf2 rs6721961 C > A) that increase the risk of type 2 diabetes mellitus and are correlated with some glycemic and metabolic traits in the Chinese Han population. METHODS: Our study recruited 141 individuals with MetS and 549 individuals without MetS to investigate the associations between three single nucleotide polymorphisms (SNPs) of Sirt1 and Nrf2 and the risk of MetS in a Chinese Han population using the PCR-CTPP method. RESULTS: This research showed that the risk of MetS was 2.41 times higher for the AA genotype (P = 0.038) and 1.94 times higher for the AG genotype (P = 0.016) compared with carriers of the GG genotype. The serum levels of low-density lipoprotein cholesterol and HOMA-IR were significantly higher (P < 0.05) in carriers of the AA genotype of Sirt1 rs7895833 than in carriers of the AG and GG genotypes in the general population. The serum level of total cholesterol in the AA genotype was lower (P = 0.033) than that in the other two genotypes. However, the genotype frequencies of Sirt1 rs2273773 and Nrf2 rs6721961 in the MetS group were not significantly different from those in the control subjects, and those two genetic variants were not correlated with metabolic traits. CONCLUSIONS: These results underscore the contributions of SNPs of Sirt1 rs7895833 to MetS susceptibility as well as glycemic and metabolic traits in a Chinese population.

The quarantine and treatment plays an important role in prevention and control of respiratory infectious diseases. It has been nearly 200 years since sanatorium model was adopted to isolate and treat patients with tuberculosis(TB). The era of the Republic of China was an important period for the model to sprout and expand. TB sanatorium was established in the early 20th century in China, and flourished in the 1930s. Establishment and changes of TB sanatoriums in Peking, Shanghai and Hangzhou during the era of the Republic of China, has great significance for sorting out the clues of China's anti-TB history, exploring historical trends of TB in China, and most important of all, summing up valuable lessons.
