ABSTRACT
Objective@#To analyze the disinfection quality and influencing factors of nurseries in Nanjing during 2019-2021, so as to provide a scientific basis for optimizing preventive disinfection strategies and measures in nurseries.@*Methods@#Environmental samples from 389 nurseries in Nanjing from January 2019 to December 2021 were tested, and the change of disinfection quality qualification rate was compared.@*Results@#The overall disinfection qualification rate of nurseries of year 2019-2021 were 96.32%, 95.85% and 94.60%, respectively, showing a downward trend ( χ 2 trend =8.67, P <0.05). Specifically, disinfection qualification rate of object surfaces, staff hands and tableware showed a downward trend, while the disinfection qualification rate of dynamic air showed an upward trend, and the differences were statistically significant ( χ 2 trend =23.17, 12.32, 5.37, 21.48, P <0.05). The total qualification rate of disinfection in Jiangning and Liuhe districts increased during 2019-2021( χ 2 trend =21.46, 24.05, P <0.05).@*Conclusion@#Disinfection quality of nurseries in Nanjing has declined by year during 2019-2021, especially the object surfaces and staff hands. It is urgent to optimize and refine the strategies and measures for preventive disinfection in nurseries, strengthen the training of personnel on disinfection knowledge, and ensure the quality of disinfection in nurseries.
ABSTRACT
Balanitesaegyptiaca(L.) Delile (Zygophyllaceae), is used in traditional medicine for the treatment of intestinal worms, wounds, and inflammatory diseases. The purpose of this study is to assess the anti-proliferative effect and to analyse the pro-apoptotic and cell cycle arrest activities of B. aegyptiacaroot bark extract and fractions against colorectal cancer cells HCT-116 and HT-29. The cytotoxicity of the crude extract and fractions were evaluated by MTS assay. The most active fractionwas subjected to crystal violet assay, Hoechst staining, cell cycle arrest, and annexin V/PI assays on cancer cells to highlight its mechanismsof action. The ethyl acetate fraction demonstrated the most cytotoxic effect on HCT-116 and HT-29 with IC50values ranging between 3 and 4 μg/mL. At 10 μg/mL in the cell cycle arrest assay, the fraction increased G1 phase by 3.83% on HCT-116 and by 8.6% on HT-29 whilst G2/M phase was decreased by 5.63% on HCT-116 and by 6.62% on HT-29. Moreover, apoptotic cells were increased by 11.4% on HCT-116. The results suggest a potential source of anticancer molecules against colorectal cancer for isolation from the ethyl acetate fraction
ABSTRACT
@# Objective: : To observe the short-term efficacy and toxicity of apatinib monotherapy as well as docetaxel plus cisplatin in advanced gastric cancer. Method: : According to inclusion and exclusion criteria, 108 patients with advanced gastric cancer in the 105th Hospital of PLA were selected. According to random table grouping method, there were 54 cases in group A and 54 cases in group B. Patients in group A received continuous oral administration of apatinib alone, while group B received docetaxel plus cisplatin chemotherapy, with 3 weeks as a cycle and 4 cycles for a course. The efficacy and side effects were evaluated 3 months later. Results: : In groupA, there were 4 cases of CR, 25 cases of PR, 18 cases of SD and 7 cases of PD; the ORR was 53.7% and DCR was 87%. In group B, there were 2 cases of CR, 19 cases of PR, 21 cases of SD and 12 cases of PD; the ORR was 38.9% and DCR was 77.8%. The ORR and DCR in group A were significantly better than those in group B (P<0.05). The main adverse reactions were gastrointestinal reaction, myelosuppression, hypertension and hand-foot syndrome, all of which were grade 1 to 2; The incidence of bone marrow suppression and gastrointestinal reaction in group A was lower than that in group B (P<0.05), while the incidence of hand-foot syndrome and hypertension in group B was lower than that in group A (P<0.01). Conclusion： ：The short-term efficacy of targeted therapy of apatinib alone was better than that of docetaxel combined with cisplatin chemotherapy, and the toxicity and side effects of both regimens were controllable;Apatinib can be used as the primary regimen for the treatment of advanced gastric cancer.
ABSTRACT
Abstract Objective Hand hygiene (HH) is a critical component for controlling hospital-acquired infection (HAI). The present study was designed to develop an intervention approach to improve compliance with HH among healthcare workers in a hospital setting. Methods The HH intervention study was conducted in Guizhou Provincial People's Hospital, Guiyang, China and organized by its Department of HAI Management. It was an observational, prospective, quasiexperimental (before-after intervention) study. The study was divided into two phases: the baseline phase and the intervention phase. The investigative team included clinical monitoring staff and infection control practitioners who received a series of instructions on HH compliance, monitoring skills, and measurement of the use of HH products. Results Based on 27,852 observations in a 17-month period, the rate of compliance with HH improved from 37.78% at baseline to 75.90% after intervention. Significant improvement in compliance and an increase in consumption of HH products was observed after intervention. The per patient-day consumption of alcohol-based hand rub products and handwash agents increased by 4.75 mL and 4.55 mL, respectively. The consumption of paper towels increased 3.41 sheets per patient-day. During the same period, the prevalence rate of HAI decreased 0.83%. Conclusions This study demonstrates that a significant improvement in compliance with HH can be achieved through a systemic, multidimensional intervention approach involving all categories of healthcare workers in a hospital setting, which may result in a decrease of the HAI rate.

Background: Bullous pemphigoid (BP) is an acquired autoimmune subepidermal blistering disease characterized by circulating IgG autoantibodies directed against BP180 and BP230 hemidesmosomal proteins. Previous studies have demonstrated that antibodies against the NC16a domain of BP180 mediate BP pathogenesis, while antibodies against BP230 enhance the inflammatory response. Recently, commercial BP180-NC16a enzyme-linked immunosorbent assay (ELISA) and BP230 ELISA kits were developed to detect anti-BP180 and anti-BP230 autoantibodies in human BP sera. Aims: To evaluate the efficacy of BP180-NC16a ELISA and BP230 ELISA in the initial diagnosis of BP. Methods: Sera from 62 BP patients and 62 control subjects were tested by BP180-NC16a ELISA and BP230 ELISA and compared with findings from indirect immunofluorescence (IIF) and immunoblotting (IB) to determine the sensitivity and specificity of these assays. Results: The sensitivities of BP180-NC16a ELISA and BP230 ELISA were 87.1% (54/62) and 56.5% (35/62), respectively, and the specificities of both were 100% (62/62). Using both ELISAs for diagnosis increased the sensitivity to 95.2% (59/62) and was statistically comparable with IB sensitivity. Conclusions: ELISA is a convenient, effective, and reliable method for serodiagnosis of BP, and combined use of BP180-NC16a ELISA and BP230 ELISA can increase the sensitivity of this diagnostic approach.
ABSTRACT
Background: Previous reports have shown that indirect immunofluorescence (IIF) performed on sodium chloride-split skin (SSS) is helpful to differentiate epidermolysis bullosa acquisita (EBA) from bullous pemphigoid (BP). Antibodies of BP may bind to the epidermal side of SSS, while antibodies of EBA bind to the dermal side. Aims: To determine the accuracy of IIF-SSS in the differential diagnosis of EBA and BP utilizing immunoblotting (IB) analysis. Methods: Sera from 78 patients, diagnosed with BP by clinical features, histopathology, and direct immunofluorescence (DIF), were assayed using IIF-SSS and IB. Results: Of the 43 serum samples with an epidermal reaction to IIF-SSS assay, 42 were recognized with BP antigens (180 kDa or 230 kDa). Of the 11 serum samples with a dermal reaction pattern, 7 were recognized with the 290 kDa antigen of EBA and 3 with sera bound BP antigens. Seven serum samples with epidermal and dermal combined staining, of which 5 of them reacted with BP antigens, 1 reacted with both BP and EBA antigens. One serum sample from each group showed a negative result by IB. Approximately 9.0% (7/78) of patients diagnosed with BP using regular methods were actually EBA. Conclusions: Epidermal reaction using the IIF-SSS assay highly correlated with the diagnosis of BP. However, dermal reactions correlated poorly with EBA, with some serum samples from BP patients binding to dermal-side antigens. In both epidermal and dermal stained sera using IIF-SSS, there was a possibility of BP and EBA. Differential diagnosis should be confirmed using IB, especially in cases of dermal and double staining patterns assayed using IIF-SSS.
