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.

ObjectivePneumonia is an infectious inflammation of the alveoli， distal airway， and interstitium caused by bacterial， viral， and other pathogens. Maxing Shigantang， originated from Treatise On Cold Damage Diseases， is a classic prescription for treating pneumonia， with significant clinical efficacy. However， its treatment mechanism is still elusive. MethodIn that paper， the transcriptome-based multi-scale network pharmacology was used to reveal the overall pharmacological mechanism of Maxing Shigantang in treating pneumonia from six scales of tissue， cell， pathological process， biological process， signaling pathway， and target. ResultAt the tissue level， Maxing Shigantang mainly acted on the focal tissue of pneumonia-lung and the main inflammatory immune tissues-blood and spleen. Analysis of cell， pathological process and biological process suggested that Maxing Shigantang could treat pneumonia by reversing inflammatory and immune functions and improving cardiopulmonary and vascular injury caused by pneumonia. Analysis of signaling pathway and target showed that Maxing Shigantang regulated inflammatory immune response pathways such as "coronavirus disease-COVID-19" and "Toll-like receptor signaling pathway"， and related targets such as "MAPKAPK3" and "NRG1". ConclusionThis paper， from molecular to tissue levels， indicated Maxing Shigantang treated pneumonia mainly by regulating inflammatory immune response and improving cardiopulmonary and vascular injury.

Blast injury of the chest injury is the most common wound in modern war trauma and terrorist attacks, and is also the most fatal type of whole body explosion injury. Most patients with severe blast injury of the chest die in the early stage before hospitalization or during transportation, so first aid is critically important. At present, there exist widespread problems such as non-standard treatment and large difference in curative effect, while there lacks clinical treatment standards for blast injury of the chest. According to the principles of scientificity, practicality and advancement, the Trauma Society of Chinese Medical Association has formulated the guidance of classification, pre-hospital first aid, in-hospital treatment and major injury management strategies for blast injury of the chest, aiming to provide reference for clinical diagnosis and treatment.

Traumatic rib fractures are the most common injury in thoracic trauma. Previously，the patients with traumatic rib fractures were mostly treated non-surgically，of which 50%，especially those combined with flail chest presented chronic pain or chest wall deformities and over 30% had long-term disabilities，being unable to retain a full-time job. In the past two decades，thanks to the development of internal fixation material technology，the surgical treatment of rib fractures has achieved good outcomes. However，there are still some problems in clinical treatment，including inconsistency in surgical treatment and quality control in medical services. The current consensuses on the management of regional traumatic rib fractures published at home and abroad mainly focus on the guidance of the overall treatment decisions and plans，and relevant clinical guidelines abroad lacks progress in surgical treatment of rib fractures in recent years. Therefore，the Chinese Society of Traumatology affiliated to Chinese Medical Association and Chinese College of Trauma Surgeons affiliated to Chinese Medical Doctor Association，in conjunction with national multidisciplinary experts，formulate the Chinese Consensus for Surgical Treatment of Traumatic Rib Fractures（2021）following the principle of evidence-based medicine，scientific nature and practicality. This expert consensus puts forward some clear，applicable，and graded recommendations from aspects of preoperative imaging evaluation，surgical indications，timing of surgery，surgical methods，rib fracture sites for surgical fixation，internal fixation methods and material selections，treatment of combined injuries in rib fractures，in order to provide references for surgical treatment of traumatic rib fractures.

Objective To study the clinical characteristics and treatment of primary nasal B-cell lymphoma (PNBCL). Methods A retrospective analysis was performed based on the clinical records of 18 PNBCL cases who were treated from January 2009 to June 2015. The clinical manifestations, imaging features, diagnosis approaches and treatment of them were analyzed. Results The main symptoms were nasal obstruction and rhinorrhea. Of all patients, 15 cases were in Ann Arbor stageⅠE-ⅡE, and 3 cases were in Ann Arbor stageⅢE-Ⅳ. The median age was 51 years (12-76 years). The ratio of men to women was 11:7. Only 1 patient had B symptoms. Elevated LDH levels were observed in 4 patients. 13 patients were diffuse large B-cell lymphoma(DLBCL), 3 patients were mantle cell lymphoma, and 2 patients were Burkitt lymphoma. CT examination showed the abnormal nasal soft tissue shadow, with unilateral location and light to moderate enhancement. 14 patients received combination chemotherapy only, and 3 patients received chemotherapy and radiotherapy. Total effective rate was 82.3 % (14/17). At the time of last follow-up, 5 patients died, and the 3-year OS rate was 54.5%(6/11). Conclusions Most PNBCL patients are in Ann Arbor stageⅠE-ⅡE and B symptoms are rare, and the most common pathological types is DLBCL. The treatment for PNBCL is chemotherapy, radiotherapy can assist, but the prognosis is poor, and innovative chemotherapy regimens are necessary.

Objective To investigate the expression and clinical significance of DNMT1 and CCNA1 in different grades of cervical lesions. Methods Cervical tissues were selected from normal cervical(NC),low-grade cervical intraepithelial lesion(LSIL),high-grade cervical intraepithelial lesion(HSIL)and cervical squa-mous cell carcinoma(SCC)from each thirty patients.The expression of DNMT1 and CCNA1 mRNA and protein was examined by Western Blot analysis and qRT-PCR in cervical tissues. Results The expression of DNMT1 mRNA and protein in LSIL,HSIL and SCC was higher than in NC(F=117.93,P<0.05;F=61.24,P<0.05). Expression of DNMT1 mRNA and protein was increased steadily according to severity of cervical lesions(χ2trend=26.25,P<0.05;χ2trend=26.60,P<0.05).The expression of CCNA1 mRNA and protein in HSIL and SCC was lower than that in NC and LSIL(F = 77.04,P < 0.05;F = 57.15,P < 0.05). Expression of CCNA1 mRNA and protein was decreased steadily according to severity of cervical lesions(χ2trend=64.19,P<0.05;χ2trend=60.24,P<0.05). There was a negative correlation between expression of DNMT1 and CCNA1 protein in LSIL,HSIL,SCC (r=-0.75,-0.56,P<0.05). Conclusion In DNMT1 mRNA there is high expression of protein and in CCNA1 mRNA there is low expression of protein,but both may be related to the occurrence and development of cervical cancer.
