Objective To evaluate nasal carriage and antimicrobial resistance of bacteria in health care workers (HCWs)in an intensive care unit (ICU),and provide basis for making prevention and control measures of health-care-associated infection(HAI).Methods From April 2014 to March 2015,nasal swabs from HCWs in ICU were collected,carriage and antimicrobial resistance of bacteria were detected.Results A total of 450 nasal swab speci-mens were taken,137 strains were isolated,isolation rate was 30.44%.There were no significant difference in na-sal carriage rates of bacteria in HCWs with different genders,ages,types of work,length of service,and education-al level (P >0.05);nasal carriage rates in HCWs at different seasons were significantly different (P <0.05 ).82 strains (59.85%)were gram-negative bacteria,the major were Klebsiella pneumoniae (21 .16%)and Enterobacter aerogenes (18.98%);55 strains (40.15% )were gram-positive bacteria,the major were Staphylococcus aureus (18.98%)and Staphylococcus epidermidis (15.33%).38 (27.74% )strains were multidrug-resistant strains. 7.69% (2/26)of Staphylococcus aureus were methicillin-resistant strains,3.45%(1/29)of Klebsiella pneumoniae and 3.85%(1/26)of Enterobacter aerogenes were imipenem-resistant strains.Conclusion Nasal carriage rate of bac-teria and detection rate of multidrug-resistant organisms in HCWs in ICU is high.

AIM: To apply molecular systematic techniques to revealing the genetic diversity of medicinal plant of Dendrobium candidum and its related species in Dendrobium.METHODS: The internal transcribed spacer(ITS) as well as 5.8S rDNA sequences of 40 samples of 25 species of Dendrobium were carried out on 25 dendrobi-um samples and amplified using PCR method and sequenced.Mega 3.1 was used to analyze the genetic diversity within the genus.Phylogenetic relationships among species in Dendrobium were estimated by maximum parsimony and neighbor-joining methods to construct similar ITS trees.RESULTS: The phylogenetic analysis indicated that Dendrobium candidum had a markedly difference in the interspecies and possessed the characteristic sequence site.CONCLUSION: ITS sequences as a good molecular marker for authentication between Dendrobium and outgroup is feasibility.

Objective To evaluate the performance and clinical utility of Verigene gram-negative blood culture ( BC-GN ) assay for a rapid identification of gram-negative bacteria and resistance genes . Methods Non-repetitive blood culture samples containing gram-negative bacteria were collected from inpa-tients in the Second Affiliated Hospital of Zhejiang University School of Medicine from June to October , 2013 .BC-GN assay was performed to identify the species and genetic resistance determinants of gram -nega-tive bacteria directly from the positive blood culture bottles .VITEK MS and the VITEK 2 Compact were used for species identification and antimicrobial susceptibility test , the results of which were considered as gold standards.The resistance genes were further validated by PCR amplification and sequencing analysis .A comparison of the results and time between the BC-GN assay and routine methods was conducted . Results The detection range of BC-GN assay almost covered all of the common gram-negative bacteria .BC-GN assay showed an advantage of high accuracy in the identification of Escherichia coli (13/13), Klebsiella pneumoniae (19/24), Klebsiella oxytoca (9/9), Pseudomonas aeruginosa (39/39), Serratia marcescens (4/5), Enterobacter spp.(6/8), Citrobacter spp.(11/11), Proteus spp.(6/6) and Acinetobacter spp. (24/24) with an overall accuracy of 94.24%for the identification of mono-microbial blood culture samples . Moreover , BC-GN assay accurately identified all of the bacteria and resistance genes from the two multi -mi-crobial samples .Species identification and resistance profiles could be 42 hours earlier available by using BC-GN assay than those by using routine methods .Conclusion BC-GN assay could simultaneously and ac-curately identify bacteria and resistance determinants from blood cultures within 2 hours.More time for clini-cally effective therapy could be achieved by using BC-GN assay for the reduction of mortality associated with bloodstream infection .

Gestational diabetes mellitus is one of the most common complications of pregnancy. Poor control of maternal blood glucose during pregnancy seriously threatens the short-term and long-term health of pregnant women and fetuses. Standardized blood glucose monitoring during pregnancy can significantly reduce the short-term and long-term complications of gestational diabetes mellitus mothers and infants, and blood glucose self-monitoring is currently the most widely used and most convenient blood glucose monitoring method in clinical practice. This article reviews the related concepts, main monitoring content, current situation, influencing factors and improvement strategies of blood glucose self-monitoring in patients with gestational diabetes mellitus. The aim is to raise the attention of medical and nursing staff to blood glucose self-monitoring in patients with gestational diabetes mellitus, and provide a theoretical basis for the prevention and treatment of adverse outcomes of gestational diabetes mellitus.

This paper introduced the development of medical specialists alliance in Zhejiang University. With Jinhua Central Hospital as an example,merits and setbacks of the 3-level trusteeship model in practice were discussed,with improvement recommendations raised for progress of the hierarchical medical system.

Objective:To investigate the clinical value of neuron specific enolase (NSE) and bispectral index (BIS ) in predicting the neurological prognosis in patients with severe intracerebral hemorrhage.Methods:Patients with severe intracerebral hemorrhage admitted to the ICU of Xiaolan Hospital of Southern Medical University from January 2019 to December 2020 were selected, and serum NSE detection and BIS monitoring were performed at an early stage. According to the Glasgow outcome scale (GOS) at 90 days after intracerebral hemorrhage, the patients were divided into the good neurologic prognosis group (GOS 4-5) and poor neurologic prognosis group (GOS 1-3). The levels of NSE and BIS between the two groups were compared. Receiver operating characteristic (ROC) curve and area under the curve (AUC) were used to evaluate the predictive value of NSE, BIS and their combination in predicting neurological prognosis.Results:A total of 126 patients with severe intracerebral hemorrhage were enrolled in this study, and 32 patients (25.4%) had poor neurological prognosis. The level of NSC in the poor neurological prognosis group was significantly higher than that in the good neurologic prognosis group [28 (13.7, 50.4) ng/mL vs. 13.5 (9.6, 18.5) ng/mL, P < 0.05], while the BIS level was significantly lower than that in the good neurologic prognosis group [32 (25.2, 45) vs. 55 (48, 62.2), P <0.05]. For detection of poor neurologic outcome in patients with severe intracerebral hemorrhage, NSE and BIS yielded the AUC values of 0.768 (0.685, 0.839) and 0.866 (0.793, 0.920), respectively, with cut-off values of 21.7 ng/mL and 47, respectively. The combination of NSE and BIS yielded a remarkably higher AUC value of 0.927 (0.867, 0.966) for predicting poor neurologic outcome than each index alone ( P<0.05). Conclusions:Early monitoring of NSE and BIS can effectively predict the neurological prognosis of patients with severe intracerebral hemorrhage, and the combination of NSE and BIS can further improve the prediction efficiency.
