Objective:Until recently, no consensus has been reached about the treatment of primary tumor in patients with meta-static breast cancer, and whether or not to excise it has not yet reached agreement. This study aimed to evaluate the value of surgical and nonsurgical treatment of primary tumor by analyzing the clinical data of patients with metastatic breast cancer. Methods:This re-view includes the data of 120 metastatic breast cancer patients. Their clinical data in Xiangyang Central Hospital (Hubei province) from January 2005 to December 2012 were collected. All cases were divided into surgical and nonsurgical groups, and the overall survival and symptomatic local progression rates were analyzed. Results:The 120 patients had a median follow-up of 52 months (range=10-92 months). A total of 55 cases were in the surgical group, 30 of whom had surgery before the metastatic diagnosis, and 65 cases were in the nonsurgical group. No significant differences were observed regarding the tumor classification, lymph-node classification, and meta-static site of the tumor in the two groups. Patients in the surgical group experienced longer overall survival (49 months vs. 33 months, P=0.016) and lower rates of symptomatic local progression (14.5%vs. 46.2%, P<0.001). Conclusion:This study demonstrated that the overall survival and symptomatic local control in the surgical group were better than those in the nonsurgical group. However, this hy-pothesis remains to be proved by multicenter clinical trials.

Objective: To investigate the incidence trend of tuberculosis in Haidong City, Qinghai Province from 2006 to 2020, and the effects of age, period, and cohort on tuberculosis incidence, so as to provide the basis for enhancing the prevention and control for tuberculosis. Methods: Data of tuberculosis cases in Haidong City from 2006 to 2020 were collected from the Chinese Disease Prevention and Control Information System. Incidence rates were calculated and standardized using data from the Sixth National Population Census in 2010. The trends in incidence of tuberculosis were analyzed by annual percent change (APC). Effects of age, period and cohort on the incidence of tuberculosis were analyzed by an age-period-cohort model. Results: The crude incidence rates of tuberculosis in Haidong City from 2006 to 2020 ranged from 37.69/105 to 100.93/105, and the standardized incidence rates ranged from 42.85/105 to 115.24/105. The standardized incidence rates from 2006 to 2015 showed a decreasing trend (APC=-7.148%, P<0.05), while there was no significant trend observed from 2015 to 2020 (all P>0.05). The age-period-cohort model analysis showed that the highest incidence risk of tuberculosis in Haidong City from 2006 to 2020 was observed in the age group of 20-<25 years (RR=2.973, 95%CI: 2.353-3.756), followed by the age group of 80-<85 years (RR=2.785, 95%CI: 2.206-3.516). The incidence risk of tuberculosis was higher in the period from 2016 to 2020 (RR=1.253, 95%CI: 1.203-1.306) compared to the period from 2011 to 2015 (RR=0.796, 95%CI: 0.770-0.823). Tuberculosis incidence risk was the highest in the birth cohort from 1936 to 1940 (RR=3.050, 95%CI: 2.356-3.949), and then gradually decreased over time thereafter. Conclusions The incidence of tuberculosis in Haidong City showed a decreasing trend from 2006 to 2015, while there was no significant trend observed from 2015 to 2020. The incidence risk of tuberculosis was higher in the age groups of 20-<25 years and 80-<85 years, and the risk decreased for those born in more recent years.

Objective To quantify the correlation between isometric and isokinetic tests of core muscles during trunk rotation. Methods The strength of the core muscles of 38 healthy males was measured isometrically and isokinetically ( at 60°/s) during trunk rotation.The left and right peak rotation torque ( LPT,RPT) and the ratio of left to right torque (L/R) were analyzed using correlation and regression analysis and paired t-tests. Results The subjects' LPTs and RPTs were positively correlated ( rL =0.644,P ≤ 0.01 ;rR =0.566,P≤0.01 ) There were significant differences in the L/R ratios determined using the two tests (r=0.663,P≤0.01 ).The regression equations predicting LPT and RPT were yL =22.330 + 0.937x and yR =32.752 +0.847x,respectively.Paired t-tests showed that tL =4.562,P≤0.01 and tR =3.855,P≤0.01 during left or right rotation.There was a significant difference,but there was no significant difference in LPT/RPT. Conclusion Isometric and isokinetic tests of core muscles during trunk rotation give results which are strongly correlated.Either can correctly reflect the maximal strength of core muscles during trunk rotation.Clinicinas may reasonably choose either testing method to assess patients and guide treatment according to the patient's clinical symptoms and the severity of the problem.

Objective:To investigate the clinical efficacy of ginkgo biloba extract dense tablets combined with pitavastatin in the treatment of elderly stable coronary heart disease (SCAD), as well as its impact on patients′ thrombotic status, neutrophil-to-lymphocyte ratio (NLR), and serum high-sensitivity C-reactive protein (hs-CRP) levels.Methods:A prospective study was conducted on 82 elderly SCAD patients admitted to the 928th Hospital of PLA Joint Logistics Support Force from October 2019 to December 2020. The patients were divided into an observation group and a control group using a random number table method, with 41 patients in each group. The control group received oral pitavastatin calcium tablets, while the observation group received oral ginkgo biloba extract dense tablets on the basis of the control group. After 8 weeks of continuous treatment, the clinical efficacy of the two groups was observed. The frequency of angina attacks, thrombotic status indicators [D-dimer (D-D), fibrinogen (FIB)], peripheral blood NLR, serum hs-CRP levels were compared before and after treatment between the two groups. The incidence of adverse reactions was compared between the two groups.Results:The total effective rate of the observation group was 78.05%(32/41), which was significantly higher than 56.10%(23/41) of the control group, and the difference was statistically significant ( P<0.05). After treatment, the frequency of angina attacks [weekly attack times, duration of single attack, severity (weekly nitroglycerin usage)] in both groups significantly improved compared with before treatment (all P<0.05), and the observation group improved more significantly (all P<0.05). After treatment, plasma D-D and FIB levels in both groups significantly decreased compared with before treatment (all P<0.05), and the observation group decreased more significantly (all P<0.05). Peripheral blood NLR and serum hs-CRP levels in both groups significantly decreased compared with before treatment (all P<0.05), and the observation group was significantly lower than the control group (all P<0.05). There was no significant difference in the incidence of adverse reactions between the observation group and the control group [9.76%(4/41) vs 7.32%(3/41)] ( P>0.05). Conclusions:The overall efficacy of ginkgo biloba extract dense tablets combined with pitavastatin in the treatment of elderly SCAD is exact, which can effectively improve patients′ angina attacks, thrombotic status and inflammatory state with good safety.

Objective:To observe the efficacy and safety of albumin paclitaxel in patients with advanced breast cancer.Methods:A retrospective analysis was performed on 138 patients with advanced breast cancer admitted to Xiangyang Central Hospital from June 2018 to June 2021. The patients were divided into groups according to molecular type, number of treatment lines for albumin paclitaxel, number of metastatic sites, specific metastatic sites, past use of docetaxel and paclitaxel and combination therapy of albumin paclitaxel. Median progression-free survival (mPFS) and treatment-related adverse reactions in different subgroups treated with albumin paclitaxel were investigated. Survival curves were plotted by Kaplan-Meier method and log-rank test was performed, and multivariate analysis was performed by Cox model.Results:The mPFS of the overall population was 8.2 months. The mPFS of triple negative breast cancer, human epidermal growth factor receptor-2 (HER-2) positive breast cancer and Luminal breast cancer were 6.4 months, 11.2 months and 8.1 months respectively, with a statistically significant difference (χ 2=7.42, P=0.025) . The mPFS of patients treated with first- and second-line albumin paclitaxel was 9.5 months, and the mPFS of patients treated with third- to seventh-line was 6.3 months (χ 2=3.86, P=0.049) . The mPFS of patients with ≤3 metastatic sites was 8.1 months, and the mPFS of patients with >3 metastatic sites was 7.0 months (χ 2=0.38, P=0.535) . The mPFS of patients with liver and brain metastases was 6.8 months, and the mPFS of patients with extrahepatic and extracerebral metastases was 9.6 months (χ 2=7.53, P=0.006) . The mPFS of patients who had previously treated with docetaxel and paclitaxel was 8.2 months, and the mPFS of patients who had not previously received docetaxel or paclitaxel was 9.6 months (χ 2=0.03, P=0.862) . The mPFS of patients with albumin paclitaxel combined with targeted therapy, combined with immunotherapy, combined with chemotherapy and monotherapy were 12.1, 7.8, 9.0 and 7.1 months respectively, with a statistically significant difference (χ 2=8.96, P=0.030) . Multivariate analysis showed that molecular type (triple negative breast cancer RR=1.87, 95% CI: 1.24-4.22, P=0.008; HER-2 positive breast cancer RR=0.63, 95% CI: 0.52-0.94, P=0.042) , number of treatment lines ( RR=0.67, 95% CI: 0.32-0.86, P=0.011) , specific metastatic sites ( RR=1.26, 95% CI: 1.12-2.75, P=0.014) and combination therapy (combined with targeted therapy RR=0.74, 95% CI: 0.16-0.86, P=0.021; combined with chemotherapy RR=0.93, 95% CI: 0.48-0.96, P=0.045; combined with immunotherapy RR=0.81, 95% CI: 0.17-0.78, P=0.032) were independent factors for prognosis. The main adverse reactions were alopecia, neutropenia, peripheral neurotoxicity and rash, and there was no death caused by adverse reactions. Conclusion:Albumin paclitaxel is effective in the treatment of advanced breast cancer with controllable adverse reactions.

Objective:To investigate the current situation and influencing factors of clinical nurses'clinical decision-making ability,and provide a reference and evidence for improving and enhancing the correct clinical decision-making ability of clinical nurses.Methods:A total of 300 clinical nurses in Shaanxi Province were selected as the research subjects by using the convenience sampling method.The General Information Questionnaire,Clinical Decision-Making Scale,and Comprehensive Decision-Making Style Scale were used to conduct the investigation and study.The influencing factors of clinical nurses'clinical decision-making ability were analyzed by using single-factor analysis and multivariate linear regression.Results:The total score of clinical nurses'clinical decision-making ability was(163.85±13.78)points,reaching the high-level standard of clinical decision-making ability(146.68-200.00)points.The results of Spearman rank correlation analysis showed that there was a significant positive correlation between the total score and the score of each dimension of clinical decision-making ability and the score of rational decision-making style(P<0.05).The score of the dimension of searching for information or new information was only negatively correlated with the score of intuitive-impulsive decision-making style(P<0.05).Avoidant decision-making style was negatively correlated with the scores of seeking information or new information,clarifying goals and values,the total score of clinical decision-making ability,and the dimensions of finding alternative solutions(P<0.05).The results of multiple linear regression showed that rational decision-making style can positively affect clinical nurses'clinical decision-making ability,while avoidance decision-making style can negatively affect it.Conclusion:The clinical nurses'clinical decision-making ability has been maintained at a relatively constant high level,and it is greatly influenced by rational and avoidant decision-making styles.Medical managers need to organize targeted training activities and other measures to promote the construction of clinical nurses'rational decision-making style and minimize the influence of avoidant decision-making style,thus improving the clinical nurses'clinical decision-making ability.
