The incidence of venous thromboembolism(VTE) including deep venous thrombosis(DVT) and pulmonary embolism(PE) increases exponentially with age. Age is an independent risk factor, acute and chronic diseases and factors affecting blood coagulation and anticoagulation equilibrium are also associated with VTE. Homocysteine may be an independent risk factor for occlusive vascular disease. The author summarized the risk factor, mechanism of action, diagnosis and therapy of VTE.

Objective To study the expression of Survivin protein and its relation with the expression of Bcl-2, Bax in the tropho- blasts of human normal placenta. Methods The normal placental tissues (8 -9week ,18-23 week and 37-40week) were fixed, embed- ded, sectioned, and Survivin, Bcl-2, and Bax in the trophoblasts were detected with immunnohistochemistry. Result As the gestational age advanced , the staining intensity of Survivin in the trophoblasts was significantly decreased from the first trimester group to the second trimes- ter group to the term group (PU value: 11.74±0.8,9.95±0.43,8. 83 ~ O. 67, respectively, P <0.01 ), while the staining intensity of Bcl-2 and Bax in trophoblast was significantly increased (PU value of Bcl-2 : 4.33±0.60, 5.00±0.75,6.87±0.45, respectively, P<0.01 and PU value of Bax: 9.82±1.12,16.00±1.05,27.48±2.10, respectively, P <0.01 ). Expression of Survivin in trophoblasts has no rela- tionship with the expression of Bcl-2 and Bax (P>0.05 ). Conclusion Survivin may take part in the development of human normal pla- centa through the way of suppressing the apoptesis in trophoblasts. Expression of Survivin in trophoblasts has no relationship with the expres- sion of Bcl-2 and Bax, which indicate that they regulate apoptesis of trophoblasts via different biological pathways.

Objective:To investigate the therapeutic effect of open suture and selective suture in patients with high complexity anal fistula and its effect on anal function and complications.Methods:Prospectively selected 174 patients with high complex anal fistula who were hospitalized in the Anorectal Surgery Department of the Second People′s Hospital of Yibin City from December 2018 to December 2021 as the study subjects, including 138 males and 36 females, aged from 26 to 45 years, with an average of (35.20 ± 8.86) years. According to the admission order of patients, grouped them into single and double numbers, with single numbers being the control group ( n=87) and double numbers being the observation group ( n=87). The control group was treated with traditional incision and thread hanging therapy, while the observation group was treated with selective suture through incision and thread hanging therapy. Compared the surgical time, blood loss, surgical cost, wound healing time, and anal function at 6 months after surgery between the two groups of patients. Compared the treatment effects of two groups of patients at 6 months after surgery. Compared the postoperative complications within 6 months and recurrence within 1 year between the two groups. The measurement data subject to normal distribution were expressed by mean ± standard deviation( ± s). The two groups were compared by independent sample t test, and the count data were compared by Chi-square test. Rank sum test was used for comparison of hierarchical data. Results:The surgical time in the observation group was higher than that in the control group [(44.30 ± 8.11) min vs (42.18 ± 7.25) min, ( t=-2.44, P<0.05], and the surgical cost was higher than that in the control group [(1184.81 ± 372.68) yuan vs (835.28 ± 320.03) yuan, t=-8.75, P<0.001]. There was no statistically significant difference in blood loss data between the two groups [(19.57 ± 6.07) mL vs (18.35 ± 5.25) mL, t=-1.88, P>0.05]. The length of wound healing time in the observation group was lower than that in the control group [(24.18 ± 4.35) d vs (29.35 ± 5.08) d, t=11.09, P<0.001]. The anal function score of the observation group at 6 months after surgery was lower than that of the control group [(4.80 ± 1.21) score vs (6.71 ± 1.35) score, t=14.72, P<0.001]. All patients did not experience any loss of follow-up. In the comparison of treatment effects 6 months after surgery, the observation group had a better efficacy rating than control group ( Z=3.86, P<0.001). At 6 months after surgery, the incidence of complications in the observation group was lower than that in the control group [2.30% (2/87) vs 10.34% (9/87), χ2=4.76, P<0.05]. One year after surgery, the recurrence rate in the observation group was lower than that in the control group [2.30% (2/87) vs 10.34% (9/87), χ2=4.76, P<0.05]. Conclusion:The application of incision and thread-drawing selective suture in the treatment of patients with high complex anal fistula is beneficial to the treatment effect of patients, reduces postoperative complications, and protects the anal function of patients, with good use value.

Objective:To evaluate the clinical efficacy of omalizumab in the treatment of patients with chronic spontaneous urticaria accompanied by other allergic diseases.Methods:Clinical data were retrospectively collected from 74 patients, who were clinically diagnosed with chronic spontaneous urticaria and other allergic diseases, and received subcutaneous injections of omalizumab in the Department of Allergy, Tianjin Medical University General Hospital from June 2020 to September 2022. Types of allergic diseases, serum total IgE (tIgE) and allergen-specific IgE (sIgE) levels before treatment, treatment outcomes and adverse drug reactions were analyzed. Differences before and after treatment were assessed using paired t-test and Wilcoxon signed-rank sum test. Results:A total of 74 patients with chronic spontaneous urticaria were involved, including 29 with complicated allergic asthma (39.2%) , 61 with complicated allergic rhinitis (82.4%) , 6 with complicated atopic dermatitis (8.1%) , and 4 with food allergy (5.4%) . Before treatment, elevated serum tIgE or sIgE levels were observed in 44 (59.5%) patients. After the first omalizumab treatment, the urticaria control test (UCT) score significantly increased compared with that before treatment (16.00 [13.0.0, 16.00] vs. 6.00 [5.75, 9.00], Z = 7.39, P < 0.001) ; after 4 sessions of the omalizumab treatment, 82.5% (33/40) of the patients achieved complete control of urticaria symptoms or showed complete response. After omalizumab treatment, asthmatic attacks were decreased in 29 patients with allergic asthma, and asthma control test (ACT) scores significantly increased compared with those before treatment (21.07 ± 2.88 points [after the first treatment] vs. 18.48 ± 3.20 points [before treatment], t = 8.87, P < 0.001) ; among 61 patients with allergic rhinitis, global rhinitis symptom-based visual analog scale (VAS) scores (before treatment: 5.89 ± 1.29 points; after the first treatment: 3.28 ±1.46 points) and rhinoconjunctivitis quality of life questionnaire (RQLQ) scores (before treatment: 60.10 ± 20.53 points; after the first treatment: 37.26 ± 18.83 points) both significantly decreased after the first treatment ( t = 15.04, 10.01, respectively, both P < 0.001) , and rhinitis symptoms were relieved at the same time; skin itching was relieved in 4 patients with atopic dermatitis, and allergic symptoms after contact with food allergens were also relieved in the 2 patients with food allergy after omalizumab treatment. During the treatment, only 1 patient experienced erythematous swelling, induration, and pain at the injection site. Conclusions:In the treatment of chronic spontaneous urticaria accompanied by allergic diseases, the use of omalizumab not only effectively improved urticaria symptoms, but also well controlled allergic diseases, with a good safety profile. Multiple benefits may be achieved by the use of omalizumabin in patients with chronic spontaneous urticaria accompanied by other allergic diseases.

Liver cancer is one of the most common cancers in China. In recent years, liver cancer tends to be treated with comprehensive therapies, including surgery, ablation, interventional embolization, radiotherapy, chemotherapy, targeted therapy, immunotherapy, and liver transplantation. At present, the low surgical resectionrate is one of the main factors affecting the prognosis of liver cancer patients. Preoperative neoadjuvant therapy or conversion therapy for liver cancer can maximize the rate of surgical resection and improve the prognosis. With the rapid development of radiotherapy and immunotherapy in the comprehensive treatment of liver cancer, it has been gradually confirmed that the unique effects of preoperative radiotherapy and immune therapy for liver cancer can improve the prognosis of the patients. Therefore, this paper reviewed the research progress in the preoperative radiotherapy and immunotherapy for liver cancer by searching relevant literature and reports at home and abroad.
