Objective:To construct a follow-up evaluation index system for "Diagnosis of Brucellosis" (WS 269-2019), and provide a reference basis for the next revision and improvement of the standard.Methods:The evaluation index system for "Diagnosis of Brucellosis" (WS 269-2019) was preliminarily established by consulting relevant references and materials. The experts in the field of diagnosis, treatment, prevention and control of brucellosis were selected, and two rounds of expert consultation were carried out in the form of questionnaires using the Delphi method. The necessity and availability of evaluation indicators were scored, and suggestions for modifying and adding indicators were put forward. Based on this, a standard follow-up evaluation index system was established. At the same time, a judgment matrix was constructed combined with the Saaty scale, and the analytic hierarchy process was used to calculate the weight of each index in the system.Results:After 2 rounds of expert ( n = 10) consultation, a standard follow-up evaluation index system for "Diagnosis of Brucellosis" (WS 269-2019) was constructed with 3 first-level indexes, 8 second-level indexes and 21 third-level indexes. The positive coefficients of experts in 2 rounds of questionnaires were both 100%; the coefficient of authority of experts was 0.82; the Kendall's coefficients of concordance of first-level, second-level and third-level indexes were 0.722, 0.260, and 0.181, respectively, with P < 0.05. Among the first-level indexes, the weight of standard quality evaluation was the highest (0.364), and the weight of standard implementation status was the lowest (0.278); among the second-level indexes, the combined weight of social benefits was the highest (0.186), and the combined weight of advanced nature was the lowest (0.043); among the third-level indexes, the combined weight of timely diagnosis rate was the highest (0.096), and the combined weight of consistency with technical data was the lowest (0.009). Conclusions:The constructed follow-up evaluation index system for "Diagnosis of Brucellosis" (WS 269-2019) is scientific and reliable, which evaluated qualitatively and quantitatively, reduces the defects of a single evaluation, and provides a basis for subsequent revision and improvement of the standard.

Objective:To investigate the effect of GTPBP4 silencing by RNA interference on the radiosensitivity of esphageal cancer EC9706 cells line.Methods:The expression data of GTPBP4 in esophageal cancer tissues was obtained from public Gene Expression Omnibus (GEO) database. Recombinant plasmid-mediated RNA interference (RNAi) was employed to transfect the esophageal cancer EC9706 cell to evaluate the influence of GTPBP4 silencing on the proliferation, apoptosis and radiosensitivity of esphageal cancer EC9706 cells. The expression levels of GTPBP4 mRNA and protein and apoptosis-associated proteins of Bax, cleaved caspase-9, cleaved caspase-3 and Bcl-2 were determined by qRT-PCR and Western blot. The cell proliferation was determined by MTT assay. The changes in cell apoptosis were detected AnnexinⅤ-FITC/PI double staining flow cytometry. The variations in radiosensitivity after radiation exposure were assessed by clone formation assay.Results:The expression level of GTPBP4 in the esophageal cancer tissues was significantly higher than that in the normal adjacent esophageal tissues ( P<0.001). qRT-PCR and Western blot demonstrated that the expression levels of GTPBP4 mRNA and protein in the GTPBP4-siRNA group were significantly lower than those in the blank and negative control groups (both P<0.001), suggesting that the plasmid was successfully transfected into the EC9706 cells. MTT assay indicated that the EC9706 cell proliferation rate was significantly inhibited ( P<0.001). Flow cytometry found that the apoptosis rate was significantly increased in the GTPBP4-siRNA group ( P<0.001). After GTPBP4 gene interference combined with radiotherapy, the cell sensitivity enhancement ratio was 1.716. The apoptosis rate of EC9706 cells was significantly increased in the GTPBP4-siRNA group ( P<0.001). The expression levels of apoptosis-associated proteins including cleaved caspase-9, cleaved caspase-3 and Bax were significantly up-regulated, whereas that of Bcl-2 was significantly down-regulated in the EC9706 cells in the GTPBP4-siRNA group ( P<0.001, P=0.001, P=0.001 and P=0.005). Conclusions:GTPBP4 gene is highly expressed in human esophageal cancer tissues. RNAi technology can effectively inhibit the expression of GTPBP4 gene in the EC9706 cells, thereby suppressing cell proliferation, inducing cell apoptosis and enhancing the radiosensitivity of cells.

Objective To investigate the effect of c?Met inhibitor AMG?102 on proliferation and radiosensitivity in laryngeal squamous carcinoma cells. Methods The effects of AMG?102 on proliferation and radiosensitivity of laryngeal squamous carcinoma cell lines Hep?2 and KBV200 were detected by 3?(4,5?dimethy?2?thiazolyl)?2, 5?diphenyl?2H tetrazolium bromide ( MTT ) assay and colony formation assay, respectively. The apoptosis of Hep?2 and KBV200 cells was detected by flow cytometry.The expression levels of c?Met, phospho?Met (p?Met), cleaved caspase?3 and Akt/p?Akt, Erk/p?Erk were detected by Western blot. Specific small interfering RNA targeting c?Met or plasmid of c?Met were transfected into Hep?2 and KBV200 cells to investigate the cell sensitivity to AMG?102. Results Compared with KBV200 cells, Hep?2 cells were more sensitive to AMG?102 with IC50 of 14 and 9 μmol/L, respectively. The relative expression levels of c?Met and p?Met proteins in Hep?2 cells were 194.48±0.57 and 177.76±1.53, respectively, which were significantly higher than those in KBV200 cells ( 171.24 ± 1.00 and 115.37 ± 0.56, respectively, P<0.001 for both). Exogenous hepatocyte growth factor (HGF) was added to increase the expression level of p?Met protein in KBV200 cells.The results showed that AMG?102 significantly reduced the expression of p?Met in KBV200 cells treated with HGF ( P<0.001). Compared with the dimethyl sulfoxide ( DMSO) group, AMG?102 treatment combined with radiotherapy significantly increased the radiosensitivity of Hep?2 cells ( SER=1.28, P<0.001). However, AMG?102 had little effect on the radiosensitivity of KBV200 cells (SER=1.18, P=0.002). Compared with the 4 Gy radiotherapy alone group and the 5 μmol/L of AMG?102 alone treatment group, the apoptosis rate of Hep?2 cells in the combined treatment group was significantly increased. Meanwhile, the expression level of cleaved caspase?3 protein was also markedly increased. However, there were no significant changes in the apoptotic rate and cleaved caspase?3 expression in each treatment group of KBV200 cells. Compared with DMSO treatment group, the expression levels of p?Met, p?Akt and p?Erk were significantly decreased in the 4 Gy radiotherapy group, 5 μmol/L of AMG?102 treatment group and combined treatment group of Hep?2 cells. And the levels of p?Met, p?Akt and p?Erk in the combined treatment group were significantly lower than those in the 4 Gy radiotherapy alone group and 5 μmol/L of AMG?102 treatment alone group. By contrast, in KBV200 cells, the expression of p?Met, p?Akt and p?Erk in each group was not changed. The relative expression of p?Met in Hep?2 cells before and after radiotherapy at 30 min, 1 h, 4 h, 8 h, 24 h were 99.89±0.61, 138.62±1.00, 163.07±5.00, 87.80±1.85, 90.67±0.65 and 94.09±1.41, respectively. The level of p?Met was slightly increased after radiotherapy at 30 min and 1 h (P<0.001 for all), whereas it was significantly decreased from 4 h to 24 h after radiotherapy (P<0.05 for all). By contrast, the expression of p?Met in KBV200 cells did not change with time after radiotherapy (P>0.05). The sensitivity of Hep?2 cells to AMG?102 was decreased after silencing of c?Met, while the sensitivity of KBV200 cells to AMG?102 was not significantly changed ( P>0.05). Moreover, the radiosensitivity of Hep?2 cells in c?Met knockdown group had a slightly increasing trend ( SER=1.07, P=0.068). After the treatment with 10 μmol/L of AMG?102, the proliferation rate of c?Met ectopically expressed KBV200 cells was 60.05%± 3.23%, It was significantly lower than that of the blank control 90.08%±1.04% and siRNA negative control (90.12%±1.01%, P<0.001). The results suggested that the overexpression of c?Met in KBV200 cells increased the radiosensitivity to AMG?102, whereas depletion of c?Met resulted in resistance to AMG?102 in Hep?2 cells. Furthermore, the radiosensitivity of KBV200 cells that overexpressed c?Met showed a decreased trend (SER=0.7, P=0.005). Conclusions c?Met inhibitor AMG?102 has a significant inhibitory effect on the proliferation of c?Met overexpressing laryngeal squamous carcinoma cells, leading to increased radiosensitivity. It suggests that molecular targeted therapy against c?Met receptor is more effective in c?Met overexpressed subtype of laryngeal squamous cell carcinoma.

Objective: To analyze and review the clinical efficacy of acupuncture (including electroacupuncture) alone for allergic rhinitis (AR) and to compare its efficacy with antihistamines and Chinese patent medicineBi Yan Kang Tablet. Methods: The search strategy, inclusion and exclusion criteria were made according to the principle of evidence-based medicine. We performed a systematic search on China National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full-text Database (Wanfang), Chongqing VIP Database (CQVIP), Chinese Biomedical Literature Database (CBM), PubMed, Excerpta Medica Database (EMBASE), Web of Science, Cochrane Library, and Cochrane Central Register of Controlled Trials (CENTRAL) for randomized controlled trials (RCTs) of acupuncture for allergic rhinitis between January 1990 and December 2015. The quality was evaluated by Cochrane Handbook for Systematic Reviews of Interventions Version 5.1, and the meta-analysis was conducted by RevMan 5.3 version. Results: Twenty eligible RCTs were included into the meta-analysis after selection. Compared with antihistamines, the meta-analysis showed RR=1.24>1, 95%CI[1.15, 1.33],P<0.00001, indicating that acupuncture achieved a better total effective rate for AR than antihistamines; MD=–0.93<0, 95%CI[–1.22, –0.63],P<0.00001, indicating that acupuncture is better than antihistamines in decreasing the total nasal symptom score (TNSS) in AR patients; and MD=1.46>0, 95%CI[–10.84, 13.75],P=0.82, indicating that there was no statistical difference between acupuncture and antihistamines in regulating immunoglobulin E (IgE) in AR patients. Compared withBi Yan Kang Tablet, the meta-analysis has shown RR=1.50>1, 95%CI[1.30, 1.73],P<0.00001, indicating that acupuncture achieved a better total effective rate for AR than Chinese patent medicineBi Yan KangTablet. Conclusion: Acupuncture alone can achieve a better total effective rate for AR than antihistamines andBi Yan Kang Tablet. It is also better than antihistamines in improving clinical symptom scores; however, whether acupuncture is better thanBi Yan KangTablet needs further proof. As far as current data are concerned, there was no statistical difference between acupuncture and antihistamines in improving serum IgE; further study is needed in this regard. The risk of bias due to absent randomization methods or blinding implementation decreased the evidence level of the overall conclusion.
