AIM: To investigate the differences in the distribution of SRY-related HMG box 5 (SOX5) gene single nucleotide polymorphisms (SNPs) among stable chronic obstructive pulmonary disease (COPD) patients, COPD with pulmonary hypertension (PH) patients and healthy controls, and to explore the association of the SOX5 SNPs in COPD-related PH.METHODS: From April 2013 to April 2015, 250 patients with stable COPD were enrolled continuous-ly in Ningxia People’s Hospital according to COPD treatment guidelines (2013 edition).All the patients received echocar-diography, and were divided into COPD with PH group [pulmonary artery systolic pressure (PASP)≥50 mmHg, n =103] and COPD without PH group (PASP <50 mmHg, n =147).The healthy persons (matched for age, sex, race and smoking index, n =127) were selected as control group at the same period.Genotyping of SOX5 gene rs10842262 and rs11046966
loci was performed using MassARRAY genotyping system ( Sequenom).Genotype frequencies were calculated.RE-SULTS: Age, sex and smoking index showed no significantly difference between control group and COPD group, neither between COPD with PH group and COPD without PH group.Genotype frequencies of SOX5 gene rs10842262 and rs11046966 loci between control group and COPD group was of significant difference (P<0.05).Genotype frequencies of SOX5 gene rs10842262 and rs11046966 loci showed no significant difference between COPD with PH group and COPD without PH group.CONCLUSION: SOX5 gene rs10842262 and rs11046966 loci may play an important role in COPD, but not in COPD-related PH.

The new medical reform takes the major aim to facilitate the expansion of high-quality medical resources and balance the regional distribution of the resources so as to meet the people's growing demand for high-quality healthcare.To exem-plify the expansion and balance of the high-quality resources,this paper scrutinizes the cooperation between aiding and aided hos-pitals by taking a state-level regional medical center hospital in Guizhou Province as an example.With cooperation-oriented pro-jects,the hospital achieved a homogenized development with the hospitals in developed regions in management,personnel,tech-nology,discipline,and hospital culture by introducing the high-quality resources from those hospitals.Such homogenized devel-opments empower the high-quality development of health care services in the less-developed regions of southwest China.Further-more,the experience of the hospital offers a reference for the development of other aided hospitals of state-level regional medical centers under new circumstances.

In recent years, the incidence of thyroid diseases has increased significantly and ultrasound examination is the first choice for the diagnosis of thyroid diseases. At the same time, the level of medical image analysis based on deep learning has been rapidly improved. Ultrasonic image analysis has made a series of milestone breakthroughs, and deep learning algorithms have shown strong performance in the field of medical image segmentation and classification. This article first elaborates on the application of deep learning algorithms in thyroid ultrasound image segmentation, feature extraction, and classification differentiation. Secondly, it summarizes the algorithms for deep learning processing multimodal ultrasound images. Finally, it points out the problems in thyroid ultrasound image diagnosis at the current stage and looks forward to future development directions. This study can promote the application of deep learning in clinical ultrasound image diagnosis of thyroid, and provide reference for doctors to diagnose thyroid disease.

Objective:
Investigated the status quo of quality control of cancer chemotherapy in hospitals in Beijing to discover the main problems and provide the improvement measures.
Methods:
One medical record of cancer chemotherapy was taken every month for examination of quality control, and a total of 10 medical records in each hospital were examined. A total of 756 medical records from 76 hospitals were examined.
Results:
The results of analysis showed that the overall standardization and quality control of cancer chemotherapy was positively correlated with the grade of hospital. Only 36.8% of the hospitals were equipped with Pharmacy Intravenous Admixture Services (PIVAS). In terms of quality control of chemotherapy and medicine, the department of oncology had better performance than other departments (

Objective:To retrospectively analyze the treatment status of tyrosine kinase inhibitors (TKI) in newly diagnosed patients with chronic myeloid leukemia (CML) in China.Methods:Data of chronic phase (CP) and accelerated phase (AP) CML patients diagnosed from January 2006 to December 2022 from 77 centers, ≥18 years old, and receiving initial imatinib, nilotinib, dasatinib or flumatinib-therapy within 6 months after diagnosis in China with complete data were retrospectively interrogated. The choice of initial TKI, current TKI medications, treatment switch and reasons, treatment responses and outcomes as well as the variables associated with them were analyzed.Results:6 893 patients in CP ( n=6 453, 93.6%) or AP ( n=440, 6.4%) receiving initial imatinib ( n=4 906, 71.2%), nilotinib ( n=1 157, 16.8%), dasatinib ( n=298, 4.3%) or flumatinib ( n=532, 7.2%) -therapy. With the median follow-up of 43 ( IQR 22-75) months, 1 581 (22.9%) patients switched TKI due to resistance ( n=1 055, 15.3%), intolerance ( n=248, 3.6%), pursuit of better efficacy ( n=168, 2.4%), economic or other reasons ( n=110, 1.6%). The frequency of switching TKI in AP patients was significantly-higher than that in CP patients (44.1% vs 21.5%, P<0.001), and more AP patients switched TKI due to resistance than CP patients (75.3% vs 66.1%, P=0.011). Multi-variable analyses showed that male, lower HGB concentration and ELTS intermediate/high-risk cohort were associated with lower cytogenetic and molecular responses rate and poor outcomes in CP patients; higher WBC count and initial the second-generation TKI treatment, the higher response rates; Ph + ACA at diagnosis, poor PFS. However, Sokal intermediate/high-risk cohort was only significantly-associated with lower CCyR and MMR rates and the poor PFS. Lower HGB concentration and larger spleen size were significantly-associated with the lower cytogenetic and molecular response rates in AP patients; initial the second-generation TKI treatment, the higher treatment response rates; lower PLT count, higher blasts and Ph + ACA, poorer TFS; Ph + ACA, poorer OS. Conclusion:At present, the vast majority of newly-diagnosed CML-CP or AP patients could benefit from TKI treatment in the long term with the good treatment responses and survival outcomes.

Radiotherapy is widely used in the management of advanced colorectal cancer (CRC). However, the clinical efficacy is limited by the safe irradiated dose. Sensitizing tumor cells to radiotherapy via interrupting DNA repair is a promising approach to conquering the limitation. The BRCA1-BARD1 complex has been demonstrated to play a critical role in homologous recombination (HR) DSB repair, and its functions may be affected by HERC2 or BAP1. Accumulated evidence illustrates that the ubiquitination-deubiquitination balance is involved in these processes; however, the precise mechanism for the cross-talk among these proteins in HR repair following radiation hasn't been defined. Through activity-based profiling, we identified PT33 as an active entity for HR repair suppression. Subsequently, we revealed that BAP1 serves as a novel molecular target of PT33 via a CRISPR-based deubiquitinase screen. Mechanistically, pharmacological covalent inhibition of BAP1 with PT33 recruits HERC2 to compete with BARD1 for BRCA1 interaction, interrupting HR repair. Consequently, PT33 treatment can substantially enhance the sensitivity of CRC cells to radiotherapy in vitro and in vivo. Overall, these findings provide a mechanistic basis for PT33-induced HR suppression and may guide an effective strategy to improve therapeutic gain.
