Objective To study the expression and significance of Ki-67 in gastrointestinal stromal tumors(GIST) with CD117 immunoreactive. Methods The expression of Ki-67 was detected by SP method in 25 cases of high risk GISTS, 18 cases of moderate GISTS and 33 cases of extremely low and low risk GISTS,which were compared with the follow-up results. The relationship between Ki-67 index (LI) and risk degree was analyzed. Results Forty patients with moderate and high risk GIST were followed-up, including 26 alive,12 die of GIST and 2 die of other causes. Compared with patients of extremely low and low risk GIST, Ki-67 LI＞5 % was correlated with moderate and high risk cases (P ＜0.01), meanwhile Ki-67 LI was positively correlated with tumor sizes of ＞5 cm and tumor mitotic cell count ＞5/50 HPF, but was not with locations(P ＞0.05). Conclusion Ki-67 LI＞5 %, tumor size＞5 cm and tumor mitotic cell count＞5/50 HPF are risk indicator for GIST with CD117 immunoreactive.

Objective:To construct the delirium prevention nursing program in ICU children and explore its clinical effect.Methods:The literature analysis and expert meeting method were used to construct the delirium prevention nursing program in ICU children. Using the convenient sampling method, a total of 315 ICU children who were admitted to Children's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from February to July 2020 were selected as the control group and 309 ICU children admitted from August 2020 to January 2021 were selected as the experimental group. The control group adopted routine nursing, while the experimental group adopted delirium prevention nursing program in ICU children on the basis of routine nursing. The differences in the incidence of delirium, mechanical ventilation time, ICU stay and ICU costs were compared between the two groups.Results:After the intervention, the incidence of delirium in the experimental group was 15.9% (49/309) and the ICU stay was 4.0 (2.5, 7.0) days, which were lower than 29.2% (92/315) and 5.0 (3.0, 10.0) d in the control group, and the differences were statistically significant (χ 2=15.892, Z=-2.341; P<0.05) . Conclusions:The establishment and application of delirium prevention nursing program for ICU children can effectively reduce the incidence of delirium in ICU children and length of stay in ICU.

OBJECTIVE: To explore the correlation of different glucose metabolism statues with chronic kidney disease (CKD) in middle-aged and elderly individuals in Lanzhou. METHODS: Based on the baseline data of REACTION Study in Lanzhou area, we randomly sampled 10 038 residents aged 40-75 years in 3 communities in Lanzhou, who were classified into normal glucose tolerance (NGT), impaired glucose regulation (IGR) and diabetes groups. The estimated glomerular filtration rate (eGFR) and urinary albumin-to-creatinine ratio (ACR) were used to assess the renal function and albuminuria, respectively. Binary logistic regression was performed to analyze the contribution of the risk factors to CKD. Polynominal regression was used to determine the trends of eGFR with the increment of ACR. RESULTS: Among all the participants, the prevalences of albuminuria, CKD and renal insufficiency (RI) were 26.2%, 27.4% and 2.5%, respectively. The prevalence of albuminuria, CKD and RI were significantly higher in the diabetes group than in IGR and NGT groups ( CONCLUSIONS Diabetes mellitus is a significant risk factor for albuminuria and RI, while IGR is not. Screening for albuminuria and eGFR is highly recommended for individuals with diabetes, hypertension, and obesity, especially in women and the elderly population.
