Objective:To explore the difference of blood pressure compliance rate in patients with continuous ambulatory peritoneal dialysis (CAPD) in the internet of things (IoT) follow-up and conventional care.Methods:CAPD patients from 3 peritoneal dialysis centers from May 2019 to October 2019 were included in this retrospective cohort study. They were divided into IoT group and conventional care group according to the way of follow-up. The difference in blood pressure compliance rate during 1 year of follow-up between the two groups was observed. The primary outcome was defined as the proportion of patients with blood pressure compliance rate≥85%.Results:A total of 75 patients were included in this study, in during 32 patients in IoT group and 43 patients in conventional care group. The comparison of baseline data between the two groups showed that the dialysis age of patients in IoT group was shorter ( P<0.01). After a median of 9(9, 12) months follow-up, the median blood pressure compliance rate was 85.2% (65.2%, 95.1%), and 25 patients (65.6%) in IoT group had met the target of blood pressure compliance rate≥85%, which was significantly higher than that in the conventional care group (17 cases, 39.5%) ( χ2=4.996, P=0.025). The cumulative probability of the target of blood pressure compliance rate≥85% was 97%, 90%, 90% and 52%, respectively in IoT group, while 95%, 86%, 55% and 34%, respectively in conventional care group after 3, 6, 9 and 12 months of follow-up, and the different between the two groups was significant (Log-rank χ2=4.774, P=0.029). Adjusted for age, sex and dialysis age, the multivariate Cox proportional risk regression model showed that serum creatinine level(for every 1 μmol/L increase, HR=1.002, 95% CI 1.000-1.003, P=0.033), follow-up mode (IoT follow-up vs conventional care, HR=0.023, 95% CI 0.003-0.210, P=0.001), follow-up times (for each additional time, HR=0.879, 95% CI 0.823-0.939, P<0.001) and the rate of weight compliance (for each increase of 1%, HR=0.964, 95% CI 0.939-0.991, P=0.008) was the independent influencing factors for the blood pressure compliance rate<85%. The results of subgroup analysis showed that patients with shorter dialysis age (<10 months) and in the centers where the nurses finished the PD follow-up work as part-time job had better blood pressure control in IoT follow-up. Conclusions:IoT follow-up is helpful to improve CAPD patients' blood pressure compliance rate. Elevated serum creatinine level at baseline is the independent risk factor associated with poor blood pressure compliance. However, IoT follow-up, more follow-up times and the elevated rate of weight compliance are the protective factors for blood pressure compliance. IoT follow-up mode is more recommended for patients with short dialysis age and for dialysis centers where most of the nurses are part-time.

Objective To investigate the expression of neurotrophins receptor 75NTR in human breast cancer resistant cell line and its correlation with multidrug resistance. Methods Western blot was used to detect the expression level of p75NTR protein in various breast cancer cell lines and multidrug resistant cell lines. The over-expression vector and siRNA vector of p75NTR were constructed by gene recombination method. Western blot was used to detect the expression levels of p75NTR protein in transfected p75NTR and p75NTR - siRNA breast cancer resistant cell line MDA-MB-231/ADR;the sensitivity of MDA-MB-231 and MDA-MB-231/ADR to different chemotherapeutic anticancer drug (PTX ,ADM ,GEM ,DDP ,OXA) and the multi-drug resistance effects in over-expression and knock-down p75NTR MDA-MB-231/ADR were detected by CCK-8 assay. Results Western blot result showed that the expressions of p75NTR protein in the multidrug-resistant breast cancer cell lines MDA-MB-231/ADR and MCF-7/5-FU were higher than that of other breast cancer cell lines. Over-expression of p75NTRcan up-regulate the expression of p75NTR protein in MDA-MB-231/ADR;the CCK-8 assay indicated that over-expression of p75NTR can effectively enhance the resistance of MDA-MB-231/ADR cells to ADM,GEM and OXA. Conclusion The expression of p75NTR in breast cancer resistant cell line is higher than that of its parental cell line;over-expression of p75NTR can reduce the sensitivity to chemotherapeutic drugs and promote its multidrug resistance.

Objective To explore the effect of evidence-based nursing intervention in senile patients with long-term nasal feeding.Methods Totals of 180 senile patients with long-term nasal feeding who were hospitalized from January, 2013 to June, 2015 were selected as the research objects and were randomly divided into observation group and control group according to the order of admission. Patients in the observation group were given nursing intervention and patients in the control group were given routine care. Complications of nasal feeding, amount of nasal feeding in single time and interval time of nasal feeding were compared between the two groups.Results There was no significant difference in the complications of nasal feeding between the two groups (P>0.05). But compared with the control group, the workload of the nasal feeding in the observation group was significantly reduced and the resting time of the digestive system of patients was prolonged obviously. Conclusions Application of evidence-based nursing intervention in senile patients with long-term nasal feeding can effectively reduce the workload of clinical nurses and reduce hungry sensation of patients.

A high performance liquid chromatography-inductively coupled plasma mass spectrometric ( HPLC-ICP-MS) method for analysis of selenocystine (SeCys2), selenite (SeⅣ), selenomethionine (SeMet) and selenate ( SeⅥ) was described. Chromatographic separation was performed using 8 mmol/L citric acid solution (pH 5). The potentially interfering 40Ar40Ar+ at selenium masses of m/z 80 was reduced using CH4 as a reactive cell gas in the dynamic reaction cell. The selenium species was extracted using ultrasonic extraction system with a mixture of protease K and lipase. The limits of detection for SeCys2 , SeⅣ, SeMet, and SeⅥwere observed as 0. 088, 0. 033, 0. 30, and 0. 17 ng/mL, respectively. The correlation coefficients were greater than 0 . 9995 . The recoveries were observed in the range of 95 . 1%-114 . 6%. The developed method was successfully applied for the determination of selenium species in Burdock and Panax notoginseng.

This article was aimed to study the action of antigout effects of compoundWeifu. Through the acute gouty arthritis models of rabbits and rats induced by micro-crystal sodium urate (MSU). The histopathological changes of synovial tissues among rabbits were observed. And the contents of TNF-α, IL-1β, IL-6 in rabbit serum were determined. The swelling degree of the rats’ feet and the content of prostaglandin E2 (PGE2) from the inflammatory exudate foot induced by MSU were also determined. The antigout effects of compoundWeifu were observed. The results showed that the grade of the vascular congestion, swelling and inflammatory cell infiltration in synovial tissues in the high-dose and medium-dose CompoundWeifu group had significantly improved (P <0.05). And the levels of TNF-α, IL-1β, IL-6 in serum were significantly decreased (P< 0.05, orP < 0.01). It can obviously reduce the swelling degree induced by MSU, and the level of PGE2 in the inflammatory exudate foot (P< 0.05, orP < 0.01). It was concluded that CompoundWeifu had obvious antigout effects in the study.

Objective To prospectively evaluate the risk factors of complete resection in early gastric cancer (EGC) with endoscopic submucosal dissection (ESD),and to guide the choice of treatment methods.Methods This study prospectively evaluated the endoscopic features of 66 EGCs,including the lesion size,presence or absence of ulceration,the extent of differentiation,invasion depth and entire margins of the EGC,then compared them with postoperative pathologic results and analysed these factors.Results The lesion size of the high grade intmepithelial neoplasia (H) group and the intramucosal carcinoma (M) group were mainly less than 30 mm (90.9％ vs.88.5％),but 57.1％ of the submucosal carcinoma (SM) were more than 30 mm.There was a significant difference between any two of three groups (P ＜ 0.05).Fourteen EGCs who got ulceration without invasion beyond mucosal muscularis underwent ESD successfully,and the basal or dissected margin had no residual tumor cells confirmed pathologically.And no tumor cell infiltration or lymph node metastasis was discovered.Of 45 EGCs with ESD,the underestimation rate for horizontal extent determined by white light and chromoendoscopy was higher than that of magnifying endoscopy with narrow-band imaging (ME-NBI) (15.6％ vs.2.2％,P ＜0.05).Diagnostic accuracy for the extent of differenciation by conventional endoscopy was 93.9％ (31/32,P ＞ 0.1),but it's unable to determine the extent of differentiation by ME-NBI.The accuracy of the group H was 84.8％ (28/33),that of M was 57.7％ (15/26),that of SM was 71.4％ (5/7),and there was a significant difference between group H and group M (P ＜ 0.05).Conclusion To achieve complete resection of EGC with ESD,the lesion more than 30 mm,presence of ulceration,undifferentiated type,deep infiltration should be considered as the risk factors,and it's also important to identify the horizontal extent of EGC to avoid unnecessary operation.
