Background: Cervical cancer is a common malignant tumor of the female reproductive system in the world, which is a serious threat to women's life and health. According to the latest report, the incidence of cervical cancer is 11.42 per 100 000, and the mortality rate is 3.77 per 100 000 in Yunnan Province, which is still higher than the national average. Although there have been some relevant studies on the risk factors of cervical cancer in recent years, research on ethnic minorities is lacking in Yunnan Province. Objective: To analyze and explore the related risk factors of cervical cancer in women of ethnic minorities in Yunnan Province, to provide the scientific basis for the development of cervical cancer prevention and control strategies and measures in this region. Methods: In total 1119 cervical cancer patients diagnosed by histopathology at the Yunnan Cancer Center (Yunnan Cancer Hospital) from January 2010 to December 2019 were selected as the case group. According to the 1:1 matching principle of the case–control study, 1119 patients with nonmalignant tumors of the same nationality, the same hospital, age difference less than 3 years old, were selected as the control group. Univariate and multivariate conditional logistic regression were used for statistical analysis. Results: Basic medical insurance for rural residents (OR = 3.659; P =  0.003), human papilloma virus (HPV) infection (OR  =  90.030; P <  0.001) and concurrent reproductive tract infections (OR = 1.992; P =  0.047) were risk factors for cervical cancer. Late first marriage(OR  =  0.881; P =  0.032), the number of normal childbirths ≤2 (OR  =  0.480, P =  0.033) and contraception (OR  =  0.291; P =  0.002) were positive factors for cervical cancer. Conclusion: The high incidence of cervical cancer in Yunnan minority women is the result of many factors: HPV infection is the highest risk factor for cervical cancer, women with reproductive tract infections and basic medical insurance for rural residents have a higher risk for cervical cancer; Late first marriage, the number of deliveries ≤2 and contraception are positive factors for cervical cancer.

Objective: To identify the efficacy and safety of multiple doses of intravenous tranexamic acid (IV‐TXA) following primary total knee arthroplasty (TKA) with a tourniquet. Methods: This is a single‐blind randomized controlled study that recruited osteoarthritis patients who had undergone primary unilateral TKA from May 2019 to May 2020 at our medical center. A total of 300 patients were randomly divided into three groups to receive: one dose (1 g) of IV‐TXA before skin incision combined with one dose (1.5 g) of intra‐articular tranexamic acid（IA‐TXA) followed by a single dose of IV‐TXA (1 g) for 3 h (group A); two doses of IV‐TXA (1 g) for 3 and 6 h (group B); or three doses of IV‐TXA (1 g) for 3, 6, and 12 h (group C) postoperatively. TKA with a tourniquet was performed by the same surgical team. The primary outcomes were total blood cell loss (TBL), hidden blood loss (HBL), maximum hemoglobin (Hb) drop, and transfusion rate. Secondary outcomes were levels of C‐reactive protein (CRP) and D‐dimer, and the incidence of postoperative complications. One‐way analysis of variance, subgroup analysis, and multivariate correlation analysis were used to calculate the differences among the three groups. Results: The study included 56 male and 244 female patients aged 60–80 years. The mean TBL, the mean HBL, and the maximum Hb drop in group C (471.2 ± 190.6 mL, 428.4 ± 190.3 mL, and 21.2 ± 3.8 g/L, respectively) were significantly lower than those in groups B (563.4 ± 224.6 mL, P = 0.030; 519.9 ± 226.4 mL, P = 0.033; and 23.2 ± 4.1 g/L, P = 0.001, respectively), and A (651.6 ± 254.1 mL, P < 0.001; 607.1 ± 254.3 mL, P < 0.001; and 25.1 ± 4.3 g/L, P < 0.001, respectively). No transfusions were required. The postoperative acute inflammatory reaction was less problematic for patients in Group C, and the incidence of thromboembolic events was similar among the groups (P > 0.05). In addition, there were positive correlations between the HBL and the tourniquet inflation time (r = 0.844, P < 0.001). Similarly, the level of CRP on POD1 (r = 0.393, P < 0.001) and POD3 (r = 0.149, P = 0.010), and the level of D‐dimer on POD1 (r = 0.382, P < 0.001) were positively correlated with the HBL. Conclusion: Three doses of postoperative IV‐TXA decreased blood loss and diminished the postoperative inflammatory and fibrinolytic response more than a single dose or two doses in elderly patients following TKA without increasing the incidence of adverse events.
