Objective:To construct the "Internet +" peripherally inserted central catheter (PICC) home nursing service quality evaluation index system, so as to provide objective basis for standardizing the "Internet +" PICC home nursing service quality evaluation.Methods:Based on the three-dimensional quality structure model of "structure-process-outcome", combined with literature research, semi-structured interviews, group discussions and Delphi method, 20 experts who were engaged in intravenous therapy nursing and had management or practical experience in "Internet + nursing services" were selected for two rounds of consultation to determine the "Internet?+" PICC home nursing service quality evaluation index system. The positive coefficient of experts was expressed by the effective response rate of the questionnaire and the rate of expert opinion submission. The degree of expert authority was expressed by the expert authority coefficient. The coordination degree of expert opinions was represented by the Kendall harmony coefficient. The concentration degree of expert opinions was usually expressed in terms of the importance assigned to the indicator, the coefficient of variation, and the full score rate (%) .Results:The effective response rates of the two rounds of consultation questionnaires were all 100%, with expert authority coefficients of 0.793 and 0.848 respectively. The Kendall coordination coefficients of expert opinions were 0.202-0.216 and 0.222-0.270 respectively ( P<0.05). After the second round of expert consultation, the mean importance assigned to all indicators was greater than 4.0, the coefficient of variation was less than 0.2, and the full score rate was greater than 20%. The final "Internet +"PICC home nursing service quality evaluation index system included 3 first-level indicators, 12 second-level indicators and 64 third-level indicators. Conclusions:The "Internet + " PICC home nursing service quality evaluation index system constructed is scientific, reliable and practical, and reflects the specialty characteristics. It can effectively evaluate the "Internet + " PICC home nursing service quality and provide guidance for continuous improvement.

OBJECTIVETo explore the effect of warming needling pretreatment for endometrial receptivity before frozen-thawed embryo transfer (FET).

METHODSFifty-six repeatedly embryo transfer (ET) failure patients with ultrasound showing follicular phase endometrium of C type, hysteroscopy examination presenting endometritis were randomly assigned into an observation group (25 cases) and a control group (31 cases). The patients in the observation group three months before ET were treated with antibiotics in the menstrual period, warming needle (once a day) at Zhongwan (CV 12), Tianshu (ST 25), Guanyuan (CV 4), Zhongji (CV 3), Zigong (EX-CA 1), Liangu (ST 34), Zusanli (ST 36), Shangjuxu (ST 37), Xiajuxu (ST 39) after menstruation until the ovulation stopped, and oral administration of progesterone was applied after ovulation. The patients in the control group three months before ET were treated with antibiotics in the menstrual period, and oral administration of progesterone was applied after ovulation. Continuous three menstrual periods were carried out for the both groups. The changes of endometrial thickness, type and endometrial blood flow and the outcome of FET were observed.

RESULTSEndometrial morphology and blood flow were improved after treatment in the two groups (all<0.01), with better results in the observation group (both<0.01). The embryo transplantation rate and pregnancy rate in the observation group were higher than those in the control group (both<0.01), and the early abortion rate decreased (<0.01).

CONCLUSIONSWarm needling may improve endometrial receptivity, embryo transplantation rate and pregnancy rate and decrease early abortion rate by regulating endometrial morphology and blood flow.

Objective:To investigate the protective effect of ulinastatin on sepsis-acute kidney injury (SA-AKI) by NF-κB signaling pathway.Methods:Total of 60 mice were randomly(random number) divided into sham group, cecal ligation puncture group (CLP group) and ulinastatin treatment group (CLP+UTI group). Ulinastatin treatment group was intraperitoneally injected with ulinastatin 50 000 U/kg once a day. 24 hours after operation, five mice were sacrificed, the kidney tissues were collected to observe renal histopathology by HE staining. The macrophage infiltration was observed by immunohistochemistry. The remaining mice in each group were used to calculate the survival rate of 7-day after operation. HK-2 cells were stimulated by LPS to obtain the SA-AKI model, and the cells were divided into control group, LPS group and LPS + UTI group. CCK-8 assay was used to detect cell viability, EdU assay was used to detect cell proliferation, and JC-1 assay was used to detect mitochondrial damage. The phosphorylation degree of NF-κB was detected by western blot. Inflammatory factors concentrations of cellular supernatant were detected by ELISA assay.Results:Compared with the sham group, the kidney tissue of mice in CLP group showed that kidney pathological obvious changed, the infiltration of macrophages increased, and the survival rate of mice decreased. CLP+ UTI group reduced the pathological changes and the infiltration of macrophages, improved the survival rate of mice. Compared with control group, LPS group obviously inhibited the cells activity and proliferation of HK-2 cells, damaged the mitochondrial membrane potential of HK-2 cells. Compared with LPS group, LPS+ UTI group attenuated the phosphorylation of NF-κB, decreased the secretion of inflammatory factors, rescued the activity and proliferation of HK-2 cells, and reduced the damage of HK-2 mitochondrial membrane potential.Conclusions:Ulinastatin can reduce mitochondrial damage, inhibit the secretion of inflammatory factors and improve the function of renal tubular epithelial cells through regulating NF-κB signaling pathway.

ObjectiveTo explore the mechanism of Huangqisan （HQS） in regulating autophagy to alleviate hepatic steatosis and improve non-alcoholic fatty liver disease （NAFLD） based on adenosine 5'-monophosphate-activated protein kinase （AMPK）/mammalian target of rapamycin （mTOR） signaling pathway. MethodThe main chemical components and targets of HQS and NAFLD-related targets were collected from database and the intersection targets were used for Gene Ontology （GO） functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analysis. The protein-protein interaction （PPI） network was constructed， and in vivo experimental verification was conducted. Sixty C57BL/6J male mice were randomly divided into normal control group （NCD）， model group high-fat diet （HFD）， metformin group （MET， 0.25 g·kg^-1）， low-dose Huangqisan group （HQS-L， 0.5 g·kg^-1）， and the high-dose Huangqisan group （HQS-H， 1 g·kg^-1）， with 12 mice in each group after a one-week acclimatization period. NAFLD model was induced by HFD， and intragastric administration was performed at the same time， once a day for 13 weeks. Random blood glucose， serum total cholesterol （TC）， triglyceride （TG）， non-esterified fatty acid （NEFA）， low density lipoprotein-chdesterol （LDL-C） levels， and liver TG content were determined. The liver weight was weighed， and liver index was calculated. Hematoxylin-eosin （HE） staining， oil red O staining， transmission electron microscope （TEM）， real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）， and Western blot were used to verify the effect and reveal the potential mechanism of C57BL/6J mice in vivo. ResultThrough network pharmacology analysis， combined with previous studies， it was predicted that HQS may improve NAFLD by regulating autophagy via the AMPK/mTOR signaling pathway. The result of in vivo experiment showed that， as compared with NCD group， random blood glucose， body weight， serum TC， LDL-C， NEFA， liver weight， liver index， and liver TG content of mice in the HFD groups were significantly increased （P<0.01）. HE staining showed massive lipid droplets （LDs） vacuolated， oil red O staining showed lipid accumulation in liver cells， and no obvious autophagosomes and autolysosome were observed under TEM. The relative mRNA expression of LC3A、LC3B、AMPKα1 and protein expression of AMPK， phosphory phosphorylated（p）-AMPK， and p-AMPK/AMPK were significantly down-regulated （P<0.01）， while the protein expression of microtubule-associated protein 1 light chain 3 （LC3）Ⅱ/Ⅰ and p-mTOR was significantly up-regulated （P<0.01）. As compared with HFD groups， liver weight， serum TG， and NEFA levels in HQS-L and HQS-H groups were significantly deceased （P<0.05， P<0.01）. HE staining and oil red O staining showed the improvement of liver pathological changes after HQS administration. Under TEM， a small amount of autophagosome and autolysosome were observed. Besides， liver index was significantly decreased in the HQS-L group （P<0.01）， and random blood glucose， serum TC level and liver TG content were significantly decreased in the HQS-H group （P<0.05）. The results of Western blot and Real-time PCR showed that the mRNA expression of LC3A and LC3B and the protein expression of LC3Ⅱ/Ⅰ， p-AMPK， and p-AMPK/AMPK were significantly up-regulated （P<0.01）， while the mRNA expressions of p62 and protein expression of p62 and p-mTOR were significantly down-regulated （P<0.05， P<0.01）. ConclusionHQS may promote autophagy and restore autophagy flux via the AMPK/mTOR signaling pathway to alleviate hepatic steatosis improving NAFLD.
