Background: Ticks are one of the most common external parasites in dogs, and are associated with the transmission of a number of major zoonoses, which result in serious harm to human health and even death. Also, the increasing number of pet dogs and pet owners in China has caused concern regarding human tick-borne illnesses. Accordingly, studies are needed to gain a complete understanding of the bacterial composition and diversity of the ticks that parasitize dogs. Objectives: To date, there have been relatively few reports on the analysis of the bacterial community structure and diversity in ticks that parasitize dogs. The objective of this study was to investigate the microbial composition and diversity of parasitic ticks of dogs, and assessed the effect of tick sex and geographical region on the bacterial composition in two tick genera collected from dogs in China. Methods: A total of 178 whole ticks were subjected to a 16S ribosomal RNA (rRNA) next generation sequencing analysis. The Illumina MiSeq platform targeting the V3–V4 region of the 16S rRNA gene was used to characterize the bacterial communities of the collected ticks. Sequence analysis and taxonomic assignment were performed using QIIME 2 and the GreenGene database, respectively. After clustering the sequences into taxonomic units, the sequences were quality-filtered and rarefied. Results: After pooling 24 tick samples, we identified a total of 2,081 operational taxonomic units, which were assigned to 23 phyla and 328 genera, revealing a diverse bacterial community profile. The high, moderate and low prevalent taxa include 46, 101, and 182 genera, respectively. Among them, dominant taxa include environmental bacterial genera, such as Psychrobacter and Burkholderia. Additionally, some known tick-associated endosymbionts were also detected, including ,Coxiella, Rickettsia, and Ricketssiella. Also, the potentially pathogenic genera Staphylococcus and Pseudomonas were detected in the tick pools. Moreover, our preliminary study found that the differences in microbial communities are more dependent on the sampling location than tick sex in the tick specimens collected from dogs. Conclusions The findings of this study support the need for future research on the microbial population present in ticks collected from dogs in China.

The objective was to investigate the effect of kinsenoside (Kin) treatments on macrophage polarity and evaluate the resulting protection of chondrocytes to attenuate osteoarthritis (OA) progression. RAW264.7 macrophages were polarized to M1/M2 subtypes then administered with different concentrations of Kin. The polarization transitions were evaluated with quantitative real-time polymerase chain reaction (qRT-PCR), confocal observation and flow cytometry analysis. The mechanism of Kin repolarizing M1 macrophages was evaluated by Western blot. Further, macrophage conditioned medium (CM) and IL-1 were administered to chondrocytes. Micro-CT scanning and histological observations were conducted on anterior cruciate ligament transection (ACLT) mice with or without Kin treatment. We found that Kin repolarized M1 macrophages to the M2 phenotype. Mechanistically, Kin inhibited the phosphorylation of IB, which further reduced the downstream phosphorylation of P65 in nuclear factor-B (NF-B) signaling. Moreover, Kin inhibited mitogen-activated protein kinases (MAPK) signaling molecules p-JNK, p-ERK and p-P38. Additionally, Kin attenuated macrophage CM and IL-1-induced chondrocyte damage. , Kin reduced the infiltration of M1 macrophages, promoted M2 macrophages in the synovium, inhibited subchondral bone destruction and reduced articular cartilage damage induced by ACLT. All the results indicated that Kin is an effective therapeutic candidate for OA treatment.

Research on the deposition of inhalable particles in the alveoli of the lungs is important to the causes, development for common respiratory diseases such as emphysema, and even the optimization of clinical treatment and prevention programs of them. In this paper, an experimental model was established to simulate the deposition of terminal bronchioles and pulmonary acinus particles. The deposition rate of inhalable particles with different particle sizes in the pulmonary acinus was studied under different functional residual capacity. The results showed that the particle diameter was an important factor affecting the deposition of particles in the lung alveoli. Particles with 1 μm diameter had the highest deposition rate. With the functional residual capacity increasing, particulate deposition rate significantly reduced. The results of this study may provide data support and optimization strategy for target inhalation therapy of respiratory diseases such as emphysema and pneumoconiosis. The established model may also provide a feasible experimental model for studying the deposition of inhalable particles in the pulmonary alveoli.

OBJECTIVETo explore the molecular basis for an individual with CisAB subtype of the ABO blood group.

METHODSABO antigen and serum antibody of the proband were detected with a serological method. Exons 5 to 7 of the ABO gene were amplified with PCR and sequenced bidirectionally. Allele-specific amplification for exon 6 to 7 was also carried out.

RESULTSThe proband was assigned as a CisAB phenotype based on his serological characteristics. Heterozygous variations including 220C/T, 261G/del, 297A/G, 467C/T, 646A/T, 681A/G, 771C/T, 803G/C, 829A/G and 1009A/G of the ABO gene were identified through direct sequencing, which was assigned as CisAB01var/O02 genotype. Allele-specific amplification indicated that the proband carried an O02 allele and a CisAB01var allele. Compared with A102, the CisAB01var allele has two nucleotide substitutions at 803G>C and 1009A>G, which resulted in replacement of amino acid Gly by Ala at position 268 and Arg by Gly at position 337.

CONCLUSIONThe CisAB subtype was identified with 803G>C and 1009A>G variants in the α1,3-N-acetyl-galactosaminyltransferase gene compared with that of the A102 allele.

Objective To explore the application effects of Donabedian's structure-process-outcome three-dimension quality assessment model on perioperative blood glucose management among elderly patients with hip fracture. Methods From September 2016 to April 2017, a total of 129 elderly patients with hip fracture of the Third Hospital of Hebei Medical University were numbered according to admission order. From September to December 2016, a total of 62 cases were in control group receiving routine blood glucose management. From January to April 2017, 67 cases were in observation group treated with blood glucose management based on Donabedian's three-dimension quality assessment model. And then, we compared the blood glucose on admission and before discharge, waiting time before surgery, healing time of wound and cases of hypoglycemia. At the same time, we investigated the demands of training content of medical staff (n=133). Results There was no statistical difference in the first blood glucose 24 hours after admission and 2 hours after meal of patients between two groups (P＞0.05). After intervention, the waiting time before surgery, healing time of wound and incidence rate of hypoglycemia in observation group [(3.34±0.88) d, (4.43±1.38) d and (3/67, 4.5%)]were less than those in control group [(4.63±1.41) d, (6.47±2.24) d and (10/62, 16.1%)];the fasting blood glucose and blood glucose 2 hours after meal in observation group [(5.96±1.21), (7.60±0.96) mmol/L] were lower than those in control group [(10.80±1.14), (9.94±1.98) mmol/L]one day before discharge all with significant differences (P＜ 0.05). There was also significant difference in blood glucose 2 hours after meal in observation group before and after intervention (P＜0.05). The demands of training content of medical staff (n=133) included diet management, correct usage of insulin, oral hypoglycemic agents instruction, blood glucose monitoring management;the influencing factors on implementing blood glucose management involved busy work, inconsistent dinner time, insufficient knowledge, and so forth. Conclusions Blood glucose management process based on Donabedian's three-dimension quality assessment model can effectively control perioperative blood glucose among elderly patients with hip fracture, shorten waiting time before surgery as well as healing time of wound and reduce cases of hypoglycemia which makes for overall rehabilitation of patients.

Objective To explore the implementation methods and effects of precise quality control model mediated by nursing quality indexes in quality management.Methods Fifty-seven care units with complete quality control data were collected. From January to December 2015, the 57 using the traditional quality control mode were selected as control group, whilst from January to December 201657 units were chosen for the intervention group using precision quality control mode, that was, to select the number of indicators and target values, screening quality control points, unified the acquisition path of indicators, lock the key departments and monitoring points affecting the quality to carry out quality management performance. We observed the changes of the two groups of quality indicators.Results The nine process quality indicators including wards 6S management, first aid techniques, health education, primary care, first class and critical care nursing, safe treatment, operating nursing documents,drug and sterile product quality and pass rate of identity verification were significant difference between the two groups(P<0.05). The five outcome quality indicators including hospitalized patients fall, dosing defects, hospital pressure sores, burns and urinary uncontrolled extubation rates were significant difference between the two groups(P<0.05) as well.Conclusions The quality control model, which is mediated by the nursing quality index, is helpful to improve the nursing quality. It is an effective quality control mode to achieve continuous improvement of nursing quality.
