[Value of forced expiratory volume in 6 seconds (FEV(6)) in the evaluation of pulmonary function in Chinese elderly males].
Objective: To evaluate the value of forced expiratory volume in 6 seconds (FEV(6)) in the evaluation of pulmonary function in Chinese elderly males. Methods: Pulmonary function tests of elderly who had received regular physical examination in Beijing Hospital from July 2003 to April 2015 were analyzed on subjects with the following characteristics: aged 60 years or older, completion of bronchial dilation test and able to exhale for at least six seconds. The included subjects were divided into 2 groups: 60-<80 years group and ≥80 years group. ⋯ In pulmonary function middle group, FEV(1)/FEV(6) or FEV(1)/FVC had no correlation with inspiratory capacity or residual volume/total lung capacity (all P>0.05). Conclusions: FEV(6) and FEV(1)/FEV(6) are strongly correlated with FVC and FEV(1)/FVC, and there is excellent agreement between FEV(1)/FEV(6) and FEV(1)/FVC. FEV(6) is simple, easy to operate and with less influencing factors, which can be used as a valid alternative for FVC in diagnosing airflow obstruction in elderly males.

Controlled Clinical Trial[Utilisation of electrical impedance tomography and/or ultrasound and mammography in breast disease diagnosis: a controlled study].
Objective: To investigate the diagnostic accuracy of electrical impedance tomography (EIT) for benign and malignant breast diseases incomparison to conventional ultrasonography and mammography. Methods: A total of 121 patients with 126 breast lesions who underwent mammography ultrasonography and EIT were enrolled in the study. All of these lessions were were confirmed by pathological biopsy. ⋯ The accuracy, sensitivity and specificity of EIT combined with mammography were 95.5%, 97.4% and 93.9%, respectively, which were significantly higher than those of mammography (χ(2)=13.474, P<0.001; χ(2)=8.573, P=0.003; χ(2)=5.333, P=0.021). Conclusion: When together with ultrasound or mammography, electrical impedance tomography (EIT) could be a valuable complementary examination in the diagnosis of breast diseases. Furthermore, EIT could provide very useful additional information for metabolic assessment of mammary glands, which may be used for early screening of breast diseases.

[The clinical value of SUDOSCAN in diagnosis of diabetic distal symmetrical peripheral neuropathy].
Objective: To evaluate the clinical value of SUDOSCAN in diagnosis of diabetic distal symmetrical peripheral neuropathy. Methods: According to the diagnostic criteria for multiple diabetic distal symmetrical peripheral neuropathy, a total of 130 patients with type 2 diabetes mellitus (T2DM) in Department of Endocrinology, the Affiliated Hospital of Qingdao University between August 2015 and July 2016 were divided into two groups, diabetic peripheral neuropathy group (DPN group, 50 cases) and non-diabetic peripheral neuropathy group (NDPN group, 80 cases). Additional 80 healthy volunteers were selected as healthy control group (NC group). ⋯ The hands and feet ESC were positively correlated with SCV, and the correlation coefficient were 0.425 and 0.445, respectively (both P<0.01). The area under the receiver operating characteristic curve (ROC) of hands and feet ESC to evaluate diabetic symmetrical peripheral polyneuropathy were 0.785 and 0.768 (both P<0.01). Conclusion: SUDOSCAN is a promising tool for the diagnosis of diabetic symmetrical peripheral polyneuropathy.

Randomized Controlled Trial[Application of general anesthesia combined with epidural anesthesia/analgesia in rehabilitation after gastric cancer resection].
Objective: To investigate the efficacy of general anesthesia with epidural anesthesia and postoperative epidural analgesia in terms of pain relief and post-operative functional recovery. Methods: Ninety-six patients were randomly assigned to general anesthesia and intravenous analgesia group (GI) or general anesthesia combined with epidural anesthesia and epidural analgesia group (GE). ⋯ Results: (1) The postoperative VAS scores of patients in the group GE at 2, 24, 48, and 72 hours were significantly lower than those in the group GI. (2) Compared with the group GI, the patients in group GE had earlier postoperative flatus and a shorter postoperative hospital stay (8.4 ± 2.5 vs 10.0 ± 3.2, P=0.012 8). Conclusion: General anesthesia combined with epidural anesthesia and postoperative epidural analgesia could provide better pain relief, enhance early rehabilitation and reduce the duration of hospital.

[Efficacy comparison of three vascular recanalization in patients with acute vertebrobasilar occlusion].
Objectives: To investigate the therapeutic effects of intravenous thrombolysis, intra-artery thrombolysis, mechanical thrombectomy on patients with acute vertebrobasilar occlusion. Methods: Retrospective analysis of clinical data of patients with acute vertebrobasilar occlusion, admitted to Huai'an First People's Hospital and Bingtuan Qishi Hospital from January 2014 to January 2016, was performed. According to different vascular recanalization, these patients were divided into intravenous thrombolysis group, intra-artery thrombolysis group and mechanical thrombectomy group. ⋯ The good outcome(mRS≤2) at 3 months was more frequent in the mechanical thrombectomy group than the intravenous or intra-arterial thrombolysis group (χ(2)=9.799, P=0.007). The differences of symptomatic intracranial hemorrhage rate among the three treatment groups were not statistically significant(χ(2)=5.035, P=0.081). Conclusion: As compared with the intravenous or intra-arterial thrombolysis, the mechanical thrombectomy has better efficiency and safety in the treatment of acute vertebrobasilar occlusion.
