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.

Objective To evaluate the accuracies of two-dimensional ultrasound(2D-US)and three-dimensional ultrasound virtual organ computer-aided analysis(3D-VOCAL)in measuring uterine myoma volume(UMV).Methods Forty-five patients who underwent surgical treatment for uterine myoma at Longyan First Hospital,Fujian Medical University from October 2022 to April 2023 were selected.Preoperative measurements of UMV were performed using 2D-US and 3D-VOCAL,and the measurement results were compared with the actual UMV after surgical resection to assess the accuracies and repeatabilities of the two ultrasound techniques in measuring UMV.Results The UMV measurement consistency of 3D-VOCAL(ICC=0.992)was higher than that of 2D-US(ICC=0.976),and the ICC values of 3D-VOCAL were higher than those of 2D-US in UM of different sizes(all P<0.001).Statistically significant differences among 2D-US,3D-VOCAL and postoperative measurement results was found in UM with a maximum diameter≥8 cm(P<0.05),but not in UMV and UM with a maximum diameter<8 cm(P>0.05),and the further analysis showed that in UM with a maximum diameter≥8 cm,the UMV measured by 2D-US differed from postoperative measurement results(P<0.05).The differences between 3D-VOCAL measurement results and postoperative measurement results were trivial(P>0.05).There were greater intra-and interobserver agreements by 3D-VOCAL than 2D-US in UMV measurement.Conclusion 3D-VOCAL which is superior to 2D-US in preoperative UMV measurement is a simple,efficient,and reliable method,and it can provide theoretical bases for clinical follow-up.

Objective:To understand the current situation of postpartum maternal perceived spouse support for breastfeeding, and explore its mediating role in the spouse support for breastfeeding and maternal breastfeeding self-efficacy.Methods:From October 2021 to October 2022, convenience sampling was used to select 602 postpartum women (42 days postpartum) and their spouses who underwent follow-up visits at Obstetric Clinics in four ClassⅢ hospitals in Shanghai as the research subject. A questionnaire survey was conducted using the General Information Questionnaire, Partner Breastfeeding Influence Scale (PBIS) , and Breastfeeding Self-efficacy Scale Short Form (BSES-SF) .Results:The PBIS score of 602 postpartum women was (121.07±25.41) , and the PBIS score of 602 maternal spouses was (134.37±18.94) . Pearson correlation analysis results showed that maternal perceived spouse support has a positive correlation with spouse support ( P<0.01) , and a positive correlation with maternal self-efficacy in breastfeeding ( P<0.01) ; spouse support was positively correlated with maternal self-efficacy in breastfeeding ( P<0.01) . The mediating effect analysis that maternal perceived spouse support played a complete mediating role between spouse support and maternal self-efficacy in breastfeeding. Conclusions:There are both connections and differences between maternal perceived spouse support and spouse support, and the positive promoting effect of spouse support on maternal self-efficacy in breastfeeding can be completely mediated by maternal perception. Medical and nursing staff should pay attention to the assessment of maternal perceived spouse support and guide spouse breastfeeding support behavior based on maternal needs and experiences of spouse support, so as to improve breastfeeding outcomes.

The pure breastfeeding rate in China is relatively low, and excellent father's support can improve the outcome of breastfeeding. The current situation and influencing factors of father's support for breastfeeding at home and abroad are not clear, and the evaluation methods are not yet unified. Starting from the concept of father's support for breastfeeding, this paper introduces the evaluation tools for father's support for breastfeeding according to specific and non-specific classifications, focusing on analyzing and comparing the structure and application status of various tools, so as to provide a basis for finding or constructing evaluation tools suitable for China. At the same time, this paper summarizes the influencing factors of father's support for breastfeeding from four aspects, including father's sociodemographic characteristics, breastfeeding knowledge, attitude towards breastfeeding, and psychological state, providing reference for formulating interventions to improve father's support for breastfeeding and further promote breastfeeding.

Objective:To understand the present situation of self-acceptance of elderly in nursing home and explore its influencing factors, so as to provide basis for improving self-acceptance level of elderly in nursing home.Methods:Totally 415 elderly people in 3 Medical and nursing homes in Fuyang city of Anhui province were selected by Self-Acceptance Scale, and influencing factors were analyzed.Results:The total score of Self-Acceptance Scale of the elderly in nursing home was (44.11±7.25) points, the score rate was 67.86% (44.11/65), in the middle level; the results of multiple linear stepwise regression showed that the relationship with children, hobbies, number of children, length of stay in nursing home, frequency of visits and age were the main influencing factors ( F value was 48.228, P<0.001). Conclusion:The self-acceptance of the elderly in nursing home is in the middle level. The nursing home or social should pay attention to the higher age group and the newly admitted elderly in nursing home, give such people timely psychological guidance, help them to plan their later life, cultivate their interests and hobbies through recreational activities, and take corresponding measures to harmonize their relationship with their children in order to improve their self-acceptance level and promote mental health.

Objective:To study the efficacy of different systemic chemotherapy regimens as first-line and second-line therapy and to determine the prognostic factors for patients with advanced biliary tract cancer.Methods:The clinical data of patients with advanced biliary tract cancer who underwent systemic chemotherapy in Cancer Hospital of Chinese Academy of Medical Sciences from January 2011 to December 2018 were studied. The efficacy of chemotherapy on objective response rate (ORR) and disease control rate (DCR) were evaluated. Potential prognostic factors for survival were studied using the Cox proportional hazards models.Results:Of 151 patients enrolled into this study, there were 75 males and 76 females, with ages ranging from 31 to 77 years (median 58 years). Two treatment protocols were used: (1) 104 patients received a gemcitabine-based regimen (combined with platinums or fluorouracils) or a combination of platinums and fluorouracils, while (2) 47 patients received a combination of albumin-bound paclitaxel and S-1. The corresponding ORR for each group were 15.4%(16/104) and 27.6%(13/47), respectively, and the DCR were 65.4%(68/104) and 72.3%(34/47), respectively. Of 58 evaluable patients who received chemotherapy as a second-line therapy, 31 patients received the regimen containing gemcitabine, platinums or fluorouracils with an ORR of 3.2% (1/31) and a DCR of 35.5%(11/31); a total of 18 patients received the taxanes-based regimen with an ORR of 11.1%(2/18) and a DCR of 38.9%(7/18); 9 patients received the irinotecan-based regimen with an ORR of 22.2%(2/9) and a DCR of 44.4%(4/9). Univariate analysis showed positive liver metastasis and elevated carbohydrate antigen (CA)19-9 level to be significantly correlated with worse survival outcomes ( HR=1.540, 95% CI: 1.019-2.328, P=0.040 and HR=1.892, 95% CI: 1.123-3.188, P=0.017). Conclusion:For patients with advanced biliary tract cancer, in addition to the conventional regimens containing gemcitabine, platinums and fluorouracils, the combination of albumin-bound paclitaxel and S-1 was shown to be an effective chemotherapeutic regimen for these patients. Second-line chemotherapy was insufficient and ineffective, and an irinotecan-based regimen deserves to be further investigated. Liver metastasis and elevated CA19-9 level were worse prognosis after chemotherapy for patients with advanced biliary tract cancer.

Objective:To investigate the expressions and significances of transforming growth factor β 1 (TGF-β 1) and dimethylarginine dimethylaminohydrolase 2 (DDAH2) in different stages of early-stage lung adenocarcinoma, and to provide basis for accurate pathological diagnosis of lung adenocarcinoma. Methods:Sixty-two surgical specimens from patients with early-stage lung adenocarcinoma in Shanxi Bethune Hospital from January 2012 to June 2019 were selected. Most of the specimens contained more than one pathological type. According to the pathological types, they were divided into three groups: 18 cases of atypical adenomatous hyperplasia (AAH), 60 cases of adenocarcinoma in situ (AIS), and 55 cases of invasive carcinoma (CA) component in minimally invasive adenocarcinoma (MIA) and lepidic predominant adenocarcinoma (LPA), and the wall attached growth patterns were selected as control group. Immunohistochemistry was used to detect the expressions of TGF-β 1 and DDAH2 proteins in different pathological types of lesions and control tissues, and the correlation among them was analyzed. Results:TGF-β 1 and DDAH2 proteins were expressed in normal lung tissue epithelial cells, and the positive rates were high [46.8% (29/62) and 98.4% (61/62)]. The positive rates of TGF-β 1 and DDAH2 proteins in epithelial cells of AAH, AIS and CA increased gradually, the positive rate of TGF-β 1 protein was 16.7% (3/18), 31.7% (19/60) and 70.9% (39/55), the positive rate of DDAH2 protein was 66.6% (12/18), 81.7% (49/60) and 90.1% (49/55), and the differences of positive rates among different pathological types were statistically significant (all P < 0.01). The positive rates of TGF-β 1 and DDAH2 protein in interstitial fibroblasts of normal lung tissue, AAH, AIS and CA increased gradually, the positive rate of TGF-β 1 protein was 11.3% (7/62), 61.1% (11/18), 72.3% (44/60), and 83.6% (46/55), the positive rate of DDAH2 protein was 0 (0/62), 22.2% (4/18), 65.0% (39/60), and 98.2% (54/55), and the differences of positive rates among different pathological types were statistically significant (all P < 0.01). In lung adenocarcinoma tissues, there was a positive correlation between the expression of TGF-β 1 in epithelial cells and the expression of DDAH2 in interstitial fibroblasts ( r = 0.221, P = 0.011). Conclusions:The expression trend of TGF-β 1 and DDAH2 proteins in different pathological types of early-stage lung adenocarcinoma lesions may relate to the degree of lesions. The combined detection of TGF-β 1 and DDAH2 proteins is expected to be a biomarker for the auxiliary diagnosis of early-stage lung adenocarcinoma with different pathological types.

Objective:To study the effects of hyperbaric oxygen (HBO) therapy on immune function and quality of life in patients with breast cancer undergoing radiochemotherapy.Methods:A total of 100 breast cancer patients admitted in the Department of General Surgery of Fujian Provincial Hospital South Branch from the February of 2015 to the February of 2018 were selected as the study objects, and were divided into observation group and control group according to the random number table method, with 50 cases in each group. Patients in the control group were treated with chemoradiotherapy and other routine clinical symptomatic treatments. Patients in the observation group were treated with HBO therapy on the basis of the treatments of the control group. One week after treatment, the occurrence of ischemic necrosis of flap, subcutaneous hydrops, incision infection, and edema of the affected limbs were all evaluated and recorded. After 5 courses of treatment, the changes of WBC, PLT, hemoglobin content, and serum immune function indexes, CD4 + , CD8 + , and CD4 + /CD8 + of both the two groups before and after treatment were detected and compared. Results:After 5 courses of treatment, the occurrence of ischemic necrosis of flap, subcutaneous hydrops, incision infection, and edema of the affected limbs of the observation group were significantly lower than those of the control group (χ 2=8.073, P<0.01). WBC and PLT counts, hemoglobin content in the observation group were significantly higher than those in the control group( P<0.05). Compared with the control group, CD4 + , CD8 + and CD4 + /CD8 + were significantly increased in the observation group ( P<0.05). Conclusion:HBO therapy can improve the immune function indexes of breast cancer patients after radiochemotherapy and increase PLT, WBC count, and hemoglobin content, so as to significantly reduce the incidence of postoperative complications, which is worthy of popularization and application in clinic.

OBJECTIVE: Investigate the effect of oxidative stress on the occurrence and development of laryngeal squamous cell carcinoma associated with smoking, and the clinical diagnostic value of catalase on smoking related laryngeal squamous cell carcinoma. METHOD: Collecting 119 smokers(including the smoking related laryngeal cancer group 68 cases, the control group 51 cases), the indexes of catalase (CAT), malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione (GSH), nitric oxide (NO) in blood plasma and cancerous tissue in two groups were compared. The association between these oxidative stress indicators and the occurrence and severity of smoking related laryngeal squamous cell carcinoma was analysised by SPSS 17.0. RESULT: (1) Compared with control group, the smoke frequency and amount, CAT, MDA, GSH increased significantly in the smoking related laryngeal cancer group (P = 0.000; 0.000; 0.000; 0.000; 0.000); whereas SOD, NO decreased (P = 0.000; 0.000). (2) The lower the differentiation degree, the higher the serum CAT (P = 0.000) and the higher CAT, MDA, GSH of larynx tissue (P = 0.000; 0.000; 0.000), but the lower the serum NO (P = 0.000) and the lower SOD, NO of larynx tissue (P = 0.000; 0.000); The higher the clinical stage, the higher CAT of serum and larynx tissue and the higher GSH of larynx tissue (P = 0.000; 0.001), the lower NO of larynx tissue (P = 0.009). (3) The serum CAT, MDA were independent risk factors of smoking related laryngeal squamous cell carcinoma (OR = 1.060, 2.475; P < 0.01, P < 0.05). CONCLUSION Oxidative stress is the key factor of the occurrence of smoking related laryngeal squamous cell carcinoma, and the CAT can be used as the indicator of clinical diagnosis of smoking related laryngeal squamous cell carcinoma.
