Objective:To understand application value of pathogen detection in elderly patients with respiratory infection by using multiple RT-PCR to detect 13 common pathogens of respiratory tract infection.Methods:This is a retrospective study, which included 317 elderly patients, aged 60 to 98 years with respiratory symptoms, who visited Geriatrics of the First Hospital of Shijiazhuang between June 2016 and May 2017. Sputum of each patient was collected. After the viral DNA/RNA was extracted, 13 respiratory pathogens were detected by multiplex RT-PCR and capillary electrophoresis. The clinical performance of the assay was evaluated in comparison to direct sequencing and Real-time PCR.Results:Compared with the direct sequencing and Real-time PCR, the accuracy of multiple RT-PCR was 99.93% (95% CI: 99.79%-99.98%), positive predictive value was 99.24% (95% CI: 97.78%-99.74%), negative predictive value was 100% (95% CI: 99.9%-100%), and Cohen’s kappa was 0.9958 (95% CI: 0.9652-1.026). Among the 317 elderly patients, the positive rate of respiratory infection was 75.7% (240/317). The highest was influenza A, 20.2% (64/317), mainly H3N2, 70.3% (45/64), followed by rhinovirus, adenovirus, Mycoplasma pneumoniae and influenza B, with the positive rates 15.5% (49/317), 13.6% (43/317), 11.0% (35/317) and 10.1% (32/317), respectively. In addition, 81 (25.6%) elderly patients were infected with two or more pathogens. Conclusions:Multiple RT-PCR meet the needs of clinical detection of respiratory pathogens and provide information for the prevention and treatment of respiratory system Infection.

Objective To explore the correlation between Triglyceride (TG), high density lipoprotein cholesterol (HDL-C), total cholesterol (TC) and diabetic Peripheral neuropathy, and to provide a clinical basis for the diagnosis of diabetic peripheral neuropathy. Methods A total of 48 patients with diabetic peripheral neuropathy diagnosed in our hospital from January 2017 to January 2018 were retrospectively analyzed and enrolled into the DPN group. Another 48 patients with type 2 diabetes admitted to our hospital during the same period were included in the T2DM group. The differences of triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C),low density lipoprotein cholesterol (LDL-C),and apolipoprotein B (ApoB) between the two groups were analyzed. And the correlation between these indicators and diabetic peripheral neuropathy were analyzed by logistic regression equation. Results The levels of TG, TC, LDL-C and ApoB in the DPN group were significantly higher than those in the T2DM group, and HDL-C was significantly lower in the DPN group than that in the T2DM group (P<0.05). Logistic regression equation analysis showed that TG, TC, and HDL-C, LDL-C, ApoB were risk factors for the onset of DPN (P<0.05). Conclusion The level of blood lipids in patients with diabetic peripheral neuropathy is higher than that in patients with diabetes alone. The levels of TG, TC and HDL-C,LDL-C, ApoB are closely related to the pathogenesis of DPN, which are important factors leading to neuromicrovascular disease.

BACKGROUND:Successful uterine spiral artery remodeling is necessary for normal pregnancy,in which vascular smooth muscle cells are important cells.Interferon-γ is associated with the loss of vascular smooth muscle cells during early pregnancy.However,the specific mechanism is not fully understood. OBJECTIVE:To investigate the effects of interferon-γ on migration and apoptosis of vascular smooth muscle cells through NLRP3/caspase-1/GSDMD pyroptosis pathway. METHODS:Human vascular smooth muscle cells were divided into control group and interferon-γ group.The control group was cultured normally,and the interferon-γ group was treated with 10 ng/mL interferon-γ for 24 hours.The migration ability of vascular smooth muscle cells was detected by Transwell assay.The apoptosis of vascular smooth muscle cells was detected by TUNEL assay and flow cytometry.The mRNA expression levels of NLRP3 and caspase-1 were detected by qPCR.Western blot assay was utilized to detect NLRP3,caspase-1,and cleaved N-terminal GSDMD protein expression levels. RESULTS AND CONCLUSION:Compared with the control group,the migration ability and apoptosis rate of vascular smooth muscle cells in interferon-γ group were significantly increased(P<0.05).Compared with the control group,the mRNA expression levels of NLRP3 and caspase-1 in vascular smooth muscle cells of interferon-γ group were significantly increased(P<0.05).Compared with control group,the expression levels of NLRP3,caspase-1,and cleaved N-terminal GSDMD protein in vascular smooth muscle cells in the interferon-γ group were significantly increased(P<0.05).The results suggest that interferon-γ may regulate the migration and apoptosis of vascular smooth muscle cells through NLRP3/caspase-1/GSDMD pyroptosis pathway.
10.Progress on matrix metalloproteinase inhibitors.
West China Journal of Stomatology 2017;35(2):208-214
Continuing advances in dentin bonding technology and adhesives revolutionized bonding of resin-based composite restorations. However, hybrid layers created by contemporary dentin adhesives present imperfect durability, and degradation of collagen matrix by endogenous enzymes is a significant factor causing destruction of hybrid layers. Bond durability can be improved by using enzyme inhibitors to prevent collagen degradation and to preserve integrity of collagen matrix. This review summarizes progress on matrix metalloproteinase inhibitors (including chlorhexidine, ethylenediaminetetraacetic acid, quaternary ammonium salt, tetracycline and its derivatives, hydroxamic acid inhibitors, bisphosphonate derivative, and cross-linking agents) and suggests prospects for these compounds.
