Objective. To systematically evaluate the efficacy and safety of pembrolizumab (PD-1/PD-L inhibitor) and adjuvant chemotherapy to treat NSCLC and provide evidence-based reference for clinical use. Methods. By searching the Cochrane Library, EMBASE, PubMed, and Web of Science, according to the inclusion criteria, literature selection, data extraction, and quality evaluation were carried out for the included literature. The I2 test was used to evaluate heterogeneity between studies, and the meta-analysis was performed using RevMan 5.3 software provided by Cochrane. Results. Finally, 14 relevant documents meeting the standards were included. It is a statistical difference in one-year survival rate [ OR = 1.50 , 95% CI (1.28, 1.76), P < 0.00001 , I 2 = 0 %, Z = 4.99 ]; overall response rate[OR =1.57, 95% CI (1.29, 1.90), P < 0.00001 , I 2 = 0 %, Z = 4.58 ]; progression-free survival [ OR = 2.99 , 95% CI (2.29, 3.91), P < 0.00001 , I 2 = 26 %, Z = 8.00 ]; and overall survival [ OR = 1.38 , 95% CI (1.07, 1.78), P = 0.01 , I 2 = 46 %, Z = 2.50 ] and reduces the incidence of adverse drug reactions [ OR = 2.54 , 95% CI (1.99, 3.25), P < 0.00001 , I 2 = 69 %, Z = 7.43 ]. Conclusion. Pembrolizumab adjuvant chemotherapy is effective in the treatment of advanced NSCLC, but attention should be paid to the occurrence of adverse reactions in clinical. Due to the limitations of the methodology included in the study, this conclusion required more validation of large-sample RCT. [ABSTRACT FROM AUTHOR]

Objective. A retrospective case-control study was performed to observe the effect and clinical significance of early electroacupuncture combined with enhanced recovery after surgery (ERAS) on pain perception and dysfunction after total knee arthroplasty (TKA). Methods. About 100 patients who diagnosed with TKA from February 2019 to April 2021 were enrolled in our hospital. The patients were arbitrarily assigned into control group and study group. The former group was cured with electroacupuncture in the early stage, and the latter group was intervened on the basis of early electroacupuncture combined with the concept of ERAS. The curative effect, the time of getting out of bed for the first time after operation, the time of postoperative rehabilitation, postoperative rehabilitation cost, pain score and knee joint function score, range of motion (ROM) of knee joint, low shear of whole blood viscosity, plasma viscosity, fibrinogen level, and postoperative complications were compared. Results. There exhibited no statistical difference in clinical data. In terms of the treatment effects, there were 27 cases of markedly effective, 22 cases of effective, and 1 case of ineffective in the study group, and the total effective rate was 98.00%; in the control group, 15 cases were markedly effective, 28 cases were effective, and 13 cases were ineffective, and the total effective rate was 86.00%. Compared to the control group, the total effective rate of the study group was higher (P < 0.05). And the first time to get out of bed and the postoperative rehabilitation time in the study group were lower. Compared to the control group (10113.42 ± 524.83) yuan, the postoperative rehabilitation cost in the study group (12401.71 ± 530.77) yuan was higher. In terms of the scores of VAS and HSS, there exhibited no remarkable difference before treatment (P > 0.05). After treatment, the VAS score lessened and the HSS score augmented the study group VAS score (1.76 ± 0.28); the score in the control group was lower compared to the control group (3.45 ± 0.36), and HSS scoring (83.48 ± 11.23) points higher compared to the control group (65.82 ± 10.44) points (P < 0.05). The ROM of knee joint augmented successively at the 1st, 2nd, 4th, and 8th week after treatment comparison between groups, the ROM of the knee joint in the study group at the 1st, 2nd, 4th, and 8th week was (49.47 ± 3.60)°, (64.38 ± 5.32)°, (86.93 ± 6.72)°, and (104.20 ± 9.11)°, is higher compared to the control group (46.53 ± 3.41)°, (61.52 ± 5.20)°, (78.42 ± 6.45)°, and (98.77 ± 8.67)° (P < 0.05). One day after operation, there exhibited no remarkable difference in whole blood viscosity low shear, plasma viscosity, and fibrinogen level (P > 0.05). However, there exhibited no remarkable difference in plasma viscosity and fibrinogen level at 1 day and 7 days after operation (P > 0.05). Seven days after operation, the whole blood viscosity, plasma viscosity, and fibrinogen in the study group were lower (P < 0.05). The probability of postoperative complications was compared. In the study group, there were 2 cases of limb swelling and pain, 1 case of joint stiffness, and no swelling and pain complicated with deep venous thrombosis, and the total incidence was 6.00%. In the control group, there were 5 cases of limb swelling and pain, 3 cases of joint stiffness, and 3 cases of swelling and pain complicated with deep venous thrombosis, with a total incidence of 22.00%. The incidence of adverse reactions in the study group was lower ( χ 2 = 5.317 P < 0.05). Conclusion. Early electroacupuncture combined with ERAS is of positive significance to the patients after TKA, which can reduce the pain, enhance the function of the knee joint, and promote the ROM of the knee joint, and can effectively shorten the first time out of bed and postoperative rehabilitation time and reduce whole blood viscosity low shear, plasma viscosity, and fibrinogen level, but the overall rehabilitation cost is high, and clinical application should be combined with the actual situation of patients.

Background. Recently, increasing studies have revealed that leptin is involved in the development of rheumatoid arthritis (RA). This study is aimed at exploring the association of leptin gene single nucleotide polymorphisms (SNPs) with susceptibility to RA in a Chinese population. Methods. We recruited 600 RA patients and 600 healthy controls from a Chinese population and analyzed their three leptin SNPs (rs10244329, rs2071045, and rs2167270) using the improved Multiplex Ligase Detection Reaction (iMLDR) assays. The associations of these SNPs with clinical manifestations of RA were also analyzed. Enzyme-linked immunosorbent assay (ELISA) was performed for plasma leptin determination. Results. No significant difference in either allele or genotype frequencies of these three SNPs between RA patients and healthy controls was observed (all P > 0.05). Association between the genotype effects of dominant, recessive models was also not found (all P > 0.05). No significant difference in plasma leptin levels was detected between RA patients and controls (P > 0.05). Conclusion. Leptin gene (rs10244329, rs2071045, and rs2167270) polymorphisms are not associated with RA genetic susceptibility and its clinical features in the Chinese population. [ABSTRACT FROM AUTHOR]

Chronic periodontitis (CP) is one of the most common chronic inflammatory diseases and cytokines play a pivotal role in the regulation of immune response. Interleukin-4 (IL-4) and interleukin-13 (IL-13) are anti-inflammatory cytokines and several polymorphisms of them have been proved involved in periodontal disease. This study aimed to evaluate whether three single nucleotide polymorphisms (SNPs), rs2070874 and rs2243248 from IL4 and rs1800925 from IL13, are associated with CP in a Han Chinese population consisting of 440 moderate or severe CP patients and 324 healthy controls. Genomic DNA extracted from buccal epithelial cells of the included participants were genotyped using a matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry method. No significant association between rs2070874 or rs1800925 and CP was found, while the frequencies of rs2243248 and two haplotypes C-G-T and C-T-T showed significant differences between the two groups. The results suggest that the polymorphism rs2243248 and haplotypes C-G-T and C-T-T may be associated with CP susceptibility in the present Han Chinese population. [ABSTRACT FROM AUTHOR]
