International Journal of Biomedical Engineering 2022;45(4):317-320
Objective:To explore and evaluate the effect of clinical toxicity nursing on the therapeutic effect of paclitaxel combined with cisplatin in the treatment of recurrent cervical cancer.Methods:Sixty patients with recurrent cervical cancer treated in the Second Hospital of Tianjin Medical University from May 2017 to May 2019 were randomly divided into two groups. The control group was given paclitaxel chemotherapy and routine nursing, and the study group was given paclitaxel combined with cisplatin and clinical toxicity nursing.Results:In the study group, the total effective rate of 93.3% was significantly higher than that of 73.3% in the control group ( P<0.05), and the levels of inflammatory indexes, including C-reactive protein (CRP), interleukin-6 (IL-6), white blood cell (WBC) and erythrocyte sedimentation rate (ESR) in the study group were lower than those in the control group ( P<0.05). The incidence of toxicity in the study group was 10.0% lower than that in the control group(36.7%, P<0.05). Conclusions:The use of paclitaxel combined with cisplatin chemotherapy for recurrent cervical cancer and clinical toxic reaction nursing can improve the effectiveness rate of treatment, reduce the levels of various inflammatory indicators, and reduce the incidence of toxic reactions with high safety, thus prolonging the survival time of patients, making it worthy of clinical application.

Objective To explore the effects of C/EBPα knockout in podocyte on diabetic nephropathy and its mechanisms.Methods C/EBPαloxp/loxp mice were crossed with podocin-cre mice to obtain F1 hybrids and then propagated until homozygous mice (C/EBPαf/f) were obtained.Diabetic nephropathy (DN) models were established by low-dose streptozotocin (STZ,100 mg/kg) administration after 25 weeks of normal diet or 45% high-fat diet treatment,and biochemical indicators of blood and urea were measured.The morphological characteristics and the proteins regulating oxidative stress and mitochondrial function were detected.Results The type 2 DN models were successfully constructed based on transgenic mice.The kidneys of 8-month-old C/EBPαf/f mice did not show obvious morphological changes,but after constructing DN models,they showed obvious renal impairment,inflammation and oxidative stress.Compared with wild-type DN mice,the protein levels of nephrin and E-cadherin in DN C/EBPαf/f mice with DN were significantly decreased (P < 0.01);fibronectin and Nrf2 protein levels were all increased (all P < 0.05).Keap1,phospho-AMPK and mitochondrial function related genes Pgc-1α protein levels were all decreased (all P < 0.05).Conclusion Podocyte C/EBPα knockout exacerbates diabetic nephropathy by promoting fibrosis and inhibiting Pgc-1α-mediated mitochondrial antioxidant function.

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.
