Objective:To investigate the effect of statins on the severity of coronary artery lesion in patients with coronary heart disease, and to analyze the risk factors of clinical prognosis.Methods:A retrospective cohort study was conducted. The clinical data of 156 patients with coronary heart disease and completed the second re-examination of coronary CT angiography (CCTA) who were admitted to the department of cardiovascular medicine of Peking University People's Hospital from January 2017 to December 2021 were collected. According to whether they took statins regularly according to the doctor's instructions after being diagnosed with coronary heart disease based on the first CCTA examination, the patients were divided into statin group and non-statin group, and the clinical characteristics of the two groups and the results of the second re-examination of CCTA were compared and analyzed. According to whether the patients had major adverse cardiovascular and cerebrovascular events (MACCE) within 3-5 years after diagnosis of coronary heart disease, the patients were divided into MACCE group and non-MACCE group, and the clinical characteristics of the two groups were compared and analyzed. Multivariate Logistic regression analysis was used to screen the risk factors related to the adverse prognosis (occurrence of MACCE) of patients with coronary heart disease.Results:① A total of 156 patients with coronary heart disease were enrolled, including 113 patients (72.44%) in the statin group and 43 patients (27.56%) in the non-statin group. Except for low density lipoprotein (LDL) and serum creatinine (SCr), there was no significant difference in gender, age, body mass index (BMI), basic diseases, smoking history, the first CCTA display of coronary artery lesions and plaque characteristics, the interval between the two CCTA and other laboratory indicators between the two groups. Compared with the non-statin group, the statin group had a significant reduction in the overall increase rate of coronary artery stenosis score (Gensini score) in the CCTA re-examination and the incidence of MACCE [Gensini score increase rate: 25.66% (29/113) vs. 46.51% (20/43), incidence of MACCE: 9.73% (11/113) vs. 30.23% (13/43), both P < 0.05]. ② Among 156 patients with coronary heart disease, 24 cases (15.38%) experienced MACCE within 3-5 years after diagnosis, while 132 cases (84.62%) did not experience MACCE. The proportion of patients in the MACCE group who regularly took statins after diagnosis was significantly lower than that in the non-MACCE group [45.83% (11/24) vs. 77.27% (102/132), P < 0.01], and D-dimer and glycosylated hemoglobin (HbA1c) were significantly higher than those in the non-MACCE group [D-dimer (μg/L): 148.50 (101.25, 314.75) vs. 88.10 (59.03, 132.12), HbA1c: 6.45% (6.20%, 7.93%) vs. 6.10% (5.81%, 6.92%), both P < 0.05]. Compared with the non-MACCE group, in the first CCTA examination of patients in the MACCE group, the total percentage of atheroma volume (PAV), fibrous-fat PAV, necrotic core PAV and Gensini score were significantly increased [total PAV: 43.05% (29.19%, 60.60%) vs. 24.57% (16.94%, 39.09%), fibrous-fat PAV: 18.61% (8.48%, 26.44%) vs. 6.81% (4.16%, 12.57%), necrotic core PAV: 5.96% (2.98%, 8.71%) vs. 2.29% (1.47%, 4.36%), Gensini score: 30.25 (23.50, 38.30) vs. 19.50 (13.20, 31.10), all P < 0.05]. Multivariate Logistic regression analysis showed that regular use of statins [odds ratio ( OR) = 0.282, 95% confidence interval (95% CI) was 0.110-0.727, P = 0.008], D-dimer ( OR = 1.011, 95% CI was 1.005-1.017, P < 0.001), necrotic core PAV ( OR = 1.323, 95% CI was 1.120-1.563, P = 0.001) and Gensini score ( OR = 1.038, 95% CI was 1.004-1.073, P = 0.028) were independent risk factors for MACCE within 3-5 years after diagnosis in patients with coronary heart disease. Conclusions:For patients with coronary heart disease, D-dimer, necrotic core PAV, and Gensini scores should be closely monitored. Statins can effectively alleviate the severity of coronary artery disease and reduce the occurrence of MACCE in patients with coronary artery disease.

Apoptosis is an important means to regulate cell proliferation and maintain homeostasis. Recent researches have shown that the B-cell lymphoma-2 (BCL-2) family not only plays a dominant role in the regulation of normal cell apoptosis, but also plays a crucial role in the formation of tumor genesis, progression and subsequent drug resistance mediated by the escape mode of apoptosis. The phenomenon that BCL-2 family antagonized the apoptosis induced by antitumor drugs and then acquired drug resistance has been reported in the clinical treatment of hematologic lymphatic system tumors, breast cancer, lung cancer, gastric cancer and other diseases. Thus, specific inhibitors targeting anti-apoptotic members of the BCL-2 family have emerged with the development of research. In this paper, we systematically reviewed the regulation of apoptosis mediated by BCL-2 family and the drug resistance mediated by BCL-2 family. Meanwhile, we summarized the research advances of BCL-2 family specific inhibitors to provide new strategy for solving the problems on tumor therapeutic resistance and for finding new therapeutic targets in the future.

OBJECTIVE： To systematically evaluate the efficacy and safety of Tapentadol immediate-release preparation （Tap IR） for relieving severe acute pain after brachiocephalic arteritis， and to provide evidence-based reference for rational drug use. METHODS： Retrieved from PubMed， Medline， Cochrane library， CNKI， VIP， Wanfang database and American clinical trial database， randomized controlled trials （RCTs） about Tap IR （trial group） versus Oxycodone immediate-release preparation or placebo for relieving severe acute pain after brachiocephalic arteritis were collected. After literature screening， data extraction and literature quality evaluation with modified Jadad scale， Meta-analysis was conducted by using RevMan 5.3 software. RESULTS： A total of 6 RCTs were included， involving 2 378 patients. Results of Meta-analysis showed that 48 h total pain relief value （TOTPAR48） of trial group was significantly higher than control group [MD＝35.60，95％CI（27.31， 43.88）， P＜0.000 01]. Results of sub-group analysis showed that TOTPAR48 of trial group using Tap IR 50 mg [MD＝28.68， 95％CI （18.18， 39.17），P＜0.00 001]， 75 mg [MD＝39.97， 95％CI （34.21， 45.73）， P＜0.000 01] and 100 mg[MD＝38.50， 95％CI（1.46， 75.54），P＝0.04] were significantly higher than control group； TOTPAR48 of patients who received Tap IR 75 mg were significantly higher than patients who received Tap IR 50 mg [MD＝9.04，95％ CI（4.31， 13.77），P＝0.000 2]. There was no statistical significance in the utilization rate of rescue medicine （URM） between 2 groups [RR＝1.23，95％ CI（0.84， 1.80），P＝0.29]. Subgroup analysis showed that URM in patients who received Tap IR 75 mg was significantly lower than those receiving Tap IR 50 mg [RR＝0.62，95％CI（0.41， 0.94），P＝0.02]. The total difference of 48 h pain intensity （SPID48） in trial group was significantly lower than control group [MD＝－18.96，95％CI（－37.28，－0.64），P＝0.04]. Subgroup analysis showed that SPID48 in patients who received Tap IR 75 mg was significantly higher than those receiving Tap IR 50 mg [MD＝21.66，95％CI（8.93， 34.39），P＝0.000 9]. There was no statistical significance in the total change of pain impression （PGIC） between 2 groups [RR＝0.95，95％CI（0.88， 1.03），P＝0.23]. Subgroup analysis showed that PGIC in patients who received Tap IR 75 mg was significantly higher than those receiving Tap IR 50 mg [RR＝1.07，95％CI（1.01， 1.13），P＝0.02] but significantly lower than those receiving Tap IR 100 mg [RR＝0.86，95％CI（0.77， 0.97），P＝0.01]. The incidence of nausea， vomiting， constipation， dizziness and headache in trial group were significantly lower than control group （P＜0.05）. CONCLUSIONS： Tap IR shows good therapeutic efficacy and safety for severe acute pain after brachiocephalic arteritis， and the efficacy of Tap IR might be better when the dose of Tap IR is 75 mg.

Objective To discuss the clinical efficacy of surgical treatment of pathologic vertebral surgery for thoracic and lumbar tuberculosis. Methods All of 322 cases of thoracic and lumbar spinal tuberculosis patients from December 2003 to June 2014 were retrospectively analyzed in our department. All patients were underwent debridement, fusion and nerve decompres?sion surgery. According to different fixed methods, patients were divided into pathologic vertebral surgery group (fixation complet?ed within lesions invaded motion unit) including 91 males and 100 females, with an average age of 41.53 years, and non?pathologic vertebral surgery group (long segments or short segment fixation) including 61 males and 70 females, with an average age of 42.72 years. We observed the tuberculosis cure rate, degrees of deformity, pain and neurological recovery, operative time, blood loss and complications by follow?up. Results The average follow?up time was 75.52 months in pathologic vertebral surgery group and 76.21 months in non?pathologic vertebral surgery group. The total number of pathologic vertebras in pathologic vertebral surgery group and non?pathologic vertebral surgery group were 277 and 218 respectively, and the average was 1.45 and 1.66. The total number of fixed segments was 277 in pathologic vertebral surgery group and 485 in non?pathologic vertebral surgery group, and the average fixed segments was 1.45 and 3.70. The cure rate was 85.86%in pathologic vertebral surgery group and 85.49%in non?pathologic vertebral surgery group at 6 months postoperatively, and 98.95%and 98.47%at the last follow?up time, with no signifi?cant difference between groups. Graft fusion rate was 89.00%in pathologic vertebral surgery group and 89.31%in non?pathologic vertebral surgery group 6 months postoperatively, 98.38%and 98.47%at the last follow?up time, without significant difference. In lumbar spine, the average correction of Cobb's angle was 12.4° in pathologic vertebral surgery group and 13.1° in non?pathologic vertebral surgery group, and the average angle loss was 1.3 and 1.4°, with no significant difference. In thoracolumbar, the average correction of Cobb’s angle was 10.9°in pathologic vertebral surgery group and 11.1°in non?pathologic vertebral surgery group, and the average angle loss was 1.7°and 1.5° respectively, without significant difference. However, in thoracic, the average correction of Cobb's angle was 10.2° in pathologic vertebral surgery group and 12.7° in non?pathologic vertebral surgery group, and the average angle loss was 3.6° and 2.5°respectively, with significant difference. The mean operation time was 210.45 min in pathologic verte?bral surgery group and 210.45 min in non?pathologic vertebral surgery group, with significant difference. The average blood loss was 726.12 ml in pathologic vertebral surgery group and 726.12 ml in non?pathologic vertebral surgery group, with significant dif?ference. The complication rate was 11.51%in pathologic vertebral surgery group and 11.45%in non?pathologic vertebral surgery group, with no significant difference. Conclusion Pathologic vertebral surgery surgery is a safe, effective and feasible method of operation for treatment of thoracic and lumbar tuberculosis, which can effectively preserve adjacent normal vertebral motion unit features. The thoracic surgery was less satisfactory than the lumbar and thoracolumbar surgery.
