Objective To analyze the effects of quality supervision and continuous improvement system on optimizing in-hospital diagnosis and treatment process in patients with acute ischemic stroke (AIS).Methods From September 2013 to May 2016,424 consecutive patients with AIS treated with intravenous thrombolysis and/or endovascular therapy in Changhai Hospital,the Second Military Medical University were enrolled retrospectively.They were analyzed according to the annual running process (the first year[from September 2013 to August 2014],the second year[from September 2014 to August 2015],and the third year[from September 2015 to May 2016]).The spend time and delay (DTN>60 min,DTP>90 min) rate of each treatment process in the first,second,and third year (time from door-to-imaging[DTI],door-to-needle[DTN],imaging-to-needle (ITN),door-to-groin puncture (DTP) and imaging-to-groin puncture (ITP) were compared.Taking the time periods (>median) of having significant differences of the spend time of the treatment processes as the dependent variables in the first,second,and third year,the influence of the years and treatment modalities on delay was observed.The difference of constituent ratio of the reasons for delay in intravenous thrombolysis and endovascular therapy (objective reasons/other reasons) in different years were analyzed.Results (1) DTIs were 23.0 (11.0,42.0) min,22.0 (10.1,39.0) min,and 13.0 (6.0,27.0) min,respectively,and DTNs were 50.0 (30.0,77.1) min,45.0 (30.0,70.2) min,and 36.0 (24.0,57.0) min,respectively in the first,second,and third year.The spending time was shortened year by year.There were significant differences among the different years (all P<0.01).The spending time of DTP had a tendency to be shortened,but there were significant differences among different years (P=0.06).There were no significant differences between the spending time of ITN and ITP (all P>0.05).(2) The DTN delay rates were 33.3% (40/120),20.7% (29/140),and 8.1% (9/111),respectively in the first,second,and third year.There were significant differences among the 3 years (x2=22.111,P<0.01).There were no significant differences among the DTP delay rates (P=0.08).(3) Multivariate Logistic regression analysis showed that taking the first years as a reference,the risk of DTI delay was reduced in the third year (OR,0.174,95%CI 0.101-0.298,P<0.01),the risks of DTN delay were reduced in the second and third year (OR,0.564,95%CI 0.338-0.941;OR,0.180,95%CI 0.101-0.320,all P<0.05).For simple intravenous thrombolysis,bridging therapy was a protective factor for the improvement of treatment efficiency in the DTI process (OR,0.530,95%CI 0.297-0.943,P=0.031).Compared with the bridging therapy,the direct endovascular therapy was a protective factor for DTP treatment (OR,0.427,95%CI 0.202-0.901,P=0.025).The remaining independent variables were not associated with the occurrence of DTN and DTP delay (all P>0.05).(4) During the three years,the delay of intravenous thrombolysis was mainly due to objective reasons.The constituent ratio of other reasons caused delay of intravenous thrombolysis was decreased year by year.There was no other reasons for delay in the third year).There was no significant difference in the constituent ratio of the delay reasons in endovascular treatment (x2=3.622,P=0.164).Conclusion Under the existing process and resource allocation,setting the DTN target time and implementing continuous quality improvement are conducive to the effective implementation of brain CT scan and continuous optimization of intravenous thrombolysis in the processes in AIS patients with the first diagnosis.

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.

Many factors contribute to a successful total knee arthroplasty, and postoperative coronal lower limb alignment has always been a focus of joint surgeons. Previous researches have suggested that neutral alignment can bring higher prosthesis survival rate and better knee function. However, the theory has been challenged in recent years.In this article, the author introduces the axis, alignment and osteotomy of total knee arthroplasty briefly and reviews the studies on the neutral alignment and kinematic alignment of recent years in order to provide some advice for the clinical operation.

OBJECTIVE: To explore the genetic basis for a child with Aspartylglucosaminuria (AGU). METHODS: Clinical data of the patient was analyzed. The child was subjected to trio-whole exome sequencing (WES) and copy number variation sequencing (CNV-seq), and candidate variant was verified by Sanger sequencing. RESULTS: The child was found to harbor homozygous c.319C>T (p.Arg107*) nonsense variant of the AGA gene, for which both of his parents were heterozygous carriers. No abnormality was found by CNV-seq analysis. The c.319C>T (p.Arg107*) variant was not found in population database, HGMD and other databases. Based on guidelines of the American College of Medical Genetics and Genomics, the variant was predicted to be pathogenic (PVS1+PM2+PP3). CONCLUSION The c.319C>T variant of the AGA gene probably underlay the autosomal recessive AGU in this child. Above finding has enabled genetic counseling and prenatal diagnosis for his parents.
