Objective To evaluate the prevalence, risk factors of nocturia and nocturia-related quality of life in Beijing area. Methods Age, hypertension, cardiovascular disease, diabetes mellitus, benign prostatic hyperplasia (BPH), alcohol abuse and smoking and nocturia status were analyzed using Logistic analysis. Multiple linear regression analysis was used to identify factors predicting the Nocturia-Quality of Life score. Results 1198 adults completed this query. 411 individuals (34.3%) answered that they arose for urination during night at least twice. The nocturia incidence increased with age from 8.6% in individuals younger than 40 to 67.7% in those older than 70. Hypertension (OR 2.322;95%CI:1.387,3.887) and diabetes (OR 2. 298;95%CI:1. 066,4. 954) were possible risk factors for nocturia. In male individuals, BPH (OR 3.900;95% CI: 1.890,8.049) was another risk factor. Gender was not found associated with nocturia. Increasing nocturia episodes (regression coefficient: - 2. 564; 95% CI:-3.08,-2.049) and decreasing total sleeping hours (regression coefficient: 1.738;95 %CI:0.948,2.527) were independent factors predicting a significantly lower N-QOL score. Conclusions Hypertension, diabetes and BPH are associated with nocturia, suggesting that multiple approaches are needed for the treatment of patients with nocturia. Nocturia has significant impact on N-QOL when the patient has two or more episodes per night.

Objective To evaluate the clinical significance of quantitative sensory testing (QST) in screening diabetic peripheral neuropathy of the early stage. Methods One hundred patients with type 2 diabetes mellitus were examined by nerve conduction velocity (NCV) and QST examination. With the NCV positive as the gold criterion for screening diabetic peripheral neuropathy of the early stage, the sensitivity and specificity of QST was further analyzed for diagnosis of the early stage diabetic peripheral neuropathy. Results Among the 100 patients with type 2 diabetes mellitus,there were 41 cases positive and 59 cases negative in NCV examination. On the other hand,there were 74 cases positive,and 26 cases negative in QST. The sensitivity and specificity of QST for the diagnosis of early stage diabetic peripheral neuropathy was 97.56% (40/41) and 42.37% (25/59). Conclusions In the screening of early stage diabetic peripheral neuropathy,QST shows higher detection sensitivity,but lower specificity than NCV examination. Therefore, QST may be an examination for the supplement of the routine electromyography.

Objective To explore the impact of metabolic syndrome (MS)in bone mineral density (BMD) in elderly male type 2 diabetics (T2DM). Methods One hundred and fourty cases were divided into MS group and non-MS(NMS)group according to with or without MS. Height,weight were measured, body mass index(BMI) were calculated and the total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), glycated hemoglobin (HbA1c)were tested. The bone mineral density (BMD) was measured by dual-energy X-ray absorptiometry (DEXA). The differences among these groups were compared and the risk factors for MS were analyzed. Results The MD, BMI, TC,TG in MS group was higher than that in NMS group (P < 0.05 vs. P < 0.01),and HDL-C was lower than NMS group (P < 0.05). Correlation analysis showed that BMD was negatively correlated with age , TG , HDL-C , and was positively correlated with BMI.The results of multiple stepwise regression analysis showed that age ,HDL-C,BMI were independent risk factors for BMD. Conclusion The BMD significantly increases in T2DM with MS.Obesity and low HDL-C have positive effects in bone mass.

Driver gene mutation is one of the most important cause of non-small cell lung cancer (NSCLC), as well as the drug target of target therapy. Patients with different driver mutations have different sensitivity to target therapy drug. So it is crucial to select target drug according to respective driver mutation. Nowadays more and more driver mutation detection come into clinical use for the guidance of NSCLC target therapy as well as more detection methods and commercial reagents were developed and utilized. Clinical and laboratory staff should be more cautious to select appropriate detection targets and reagents. Therefore, the relative target driver mutation and detection reagents in target therapy of NSCLC were reviewed in this paper, according to the China National Medical Products Administration, in order to provide reference for better selection of adequate methods and reagents as well as provide advice for personalized therapy of NSCLC patients.

Objective:To explore the application of transbronchial lung cryobiopsy guided by endobronchial ultrasound sheath (EBUS-GS-TBCB) in diagnosis of nonresolving pneumonias.Methods:Sixty patients with nonresolving pneumonias from March 2019 to July 2020 in Dalian Municipal Central Hospital were selected. The patients were divided into EBUS-GS-TBCB group (31 cases) and transbronchial forcep lung biopsy guided by endobronchial ultrasound sheath(EBUS-GS-TBLB) group (29 cases) by random digits table method.Results:The diagnostic rate of nonresolving pneumonias in EBUS-GS-TBCB group was significantly higher than that in EBUS-GS-TBLB group: 87.10% (27/31) vs. 65.52% (19/29), and there was statistical difference ( χ2 = 3.90, P = 0.048). There were no statistical difference in sensitivity, specificity, accuracy, positive predictive value and negative predictive value between 2 groups ( P>0.05). There were no statistical difference inthe shortest distance from lesions to pleura, incidence of pneumothorax and incidence of bleeding between EBUS-GS-TBCB group and EBUS-GS-TBLB group: (27.42 ± 2.88) mm vs. (27.01 ± 2.37) mm, 6.45%(2/31) vs. 3.45%(1/29) and 22.58%(7/31) vs. 13.79% (4/29), P>0.05. Among the causes of nonresolving pneumonias, infectious factors accounted for 21.67% (13/60), non infectious factors accounted for 66.67% (40/60), and uncertain causes accounted for 11.67% (7/60). Conclusions:The diagnostic rate of EBUS-GS-TBCB in nonresolving pneumonias is significantly higher than EBUS-GS-TBLB, and the complications such as bleeding and pneumothorax do not increase significantly.

BACKGROUND:
Little was known about the association among time in range (TIR), time above range (TAR), time below range (TBR), and cancer mortality among patients with type 2 diabetes. We aimed to investigate the association among TIR, TAR, TBR, and the risk of cancer mortality among patients with type 2 diabetes.
METHODS:
A total of 6225 patients with type 2 diabetes were prospectively recruited in Shanghai, China. TIR was measured with continuous glucose monitoring at baseline and was defined as the average percentage of time in the target glucose range during a 24 h period. Cox proportion hazard regression analysis was used to determine the association between TIR and the risk of cancer mortality.
RESULTS:
During a mean follow-up of 7.10 years, we confirmed 237 death events related to cancer. The multivariable-adjusted hazard ratio (HR) for cancer mortality was 1.32 (95% confidence interval [CI]: 1.01-1.75) in patients with TIR ≤70% compared with those with TIR >70%. When TIR was considered as a continuous variable, the multivariable-adjusted HR for cancer mortality associated with each 10% decrease in TIR was 1.07 (95% CI: 1.02-1.14). In the site-specific analysis, a significant association between TIR as a continuous variable and the risk of hepatocellular cancer was found (HR: 1.24; 95% CI: 1.09-1.41). However, no relationship between hemoglobin A1c and cancer mortality was observed (HR: 1.04; 95% CI: 0.97-1.10).
CONCLUSIONS
The present study found an inverse association of TIR with the risk of cancer mortality among patients with type 2 diabetes. New evidence of TIR was added into the clinical practice that TIR may be an optimal target of glycemic control among patients with type 2 diabetes.
