ABSTRACT
Objective To translate the Pulmonary Embolism Quality of Life (PEmb-QoL) Scale into Chinese and evaluate its reliability and validity. Methods The Chinese version of PEmb-QoL was translated from the original,back-translated and adjusted for cultural adaptation.The reliability and validity were tested in 212 patients with PE. Results The content validity index (CVI) of the PEmb-QoL Scale was 0.910, which indicated a desirable content validity. Factor analysis ex-tracted six common factors, which explained 82.177% of variance of the total scale, and each item had high factor loading quantity (>0.4).The test-retest reliability was 0.810, and Cronbach α was 0.894. Conclusions Chinese version of PEmb-QoL has been proved to be valid and reliable.It is a valuable tool for evaluating the quality of life among patients with pulmonary embolism disease.

ABSTRACT
PURPOSE: Obstructive sleep apnea and chronic obstructive pulmonary disease are independent risk factors of cardiovascular disease (CVD), and their coexistence is known as overlap syndrome (OS). Endothelial dysfunction is the initial stage of CVD; however, underlying mechanisms linking OS and CVD are not well understood. The aim of this study was to explore whether OS can lead to more severe inflammation and endothelial apoptosis by promoting endothelial dysfunction, and to assess the intervention effects of antioxidant tempol. MATERIALS AND METHODS: Male Wistar rats (n=66) were exposed to normal oxygen [normal control (NC) group], intermittent hypoxia (IH group), cigarette smoke (CH group), as well as cigarette smoke and IH (OS group). Tempol intervention was assessed in OS group treated with tempol (OST group) or NaCl (OSN group). After an 8-week challenge, lung tissues, serum, and fresh blood were harvested for analysis of endothelial markers and apoptosis. RESULTS: The levels of intracellular adhesion molecule-1, vascular cellular adhesion molecule-1, and apoptosis in circulating epithelial cells were the highest in OS group and the lowest in NC group. These levels were all greater in IH group than in CH group, and were lower in OST group than in OS and OSN groups (all p < 0.001). CONCLUSION: Synergistic effects of IH with cigarette smoke-induced emphysema produce a greater inflammatory status and endothelial apoptosis. OS-related inflammation and endothelial cell apoptosis may play important roles in promoting cardiovascular dysfunction, and antioxidant tempol could achieve a partial protective effect.

Objective To investigate the diagnostic value of transbronchial lung biopsy (TBLB) under virtual bronchoscopic navigation (direct path), endobronchial ultrasonography with a guide sheath (GS) and rapid on-site evaluation (ROSE) for solitary pulmonary nodules (SPNs). Methods One hundred and seventy-eight patients who were underwent transbronchial lung biopsy in the Tianjin Medical University General Hospital between January 2015 to December 2016 were retrospectively evaluated. CT images of all patients showed solitary pulmonary nodules surrounded by lung tissue, and ROSE was undergone during the procedure. The patients were divided into conventional (C-TBLB) group, virtual bronchoscopic navigation (VBN) group, endobronchial ultrasonography with a guide sheath (GS) group, and virtual bronchoscopic navigation combined with endobronchial ultrasonography with a guide sheath group (combination) depending on the different devices. The diagnostic yield and the location or the effect of lesion on the diagnostic rate were compared between four groups. The coincidence rate of ROSE and the histopathological findings of TBLB were compared. The value of ROSE for the early diagnosis of disease was further evaluated. Results The diagnostic rates were 32.5％(13/40), 66.7％(24/36), 68.2％(30/44) and 75.8％(44/58) for C-TBLB group, VBN group, GS group and combination group, respectively. There were significant differences in diagnostic rates between C-TBLB group and other tree groups (χ2=8.853, 10.677 and 18.293, P0.008). The diagnostic rates for peripheral pulmonary nodules were 12.5％ (2/16), 42.9％ (6/14), 40.0％ (4/10) and 75.9％(22/29) in C-TBLB group, VBN group, GS group and combination group. The diagnostic rate was significantly higher in combination group than that of other three groups (χ2=17.434, P<0.05). The result of ROSE was consistent with result of histopathology (Kappa = 0.775, P<0.001). The sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of ROSE during transbronchial biopsy for solitary pulmonary nodules were 90.7％, 87.0％, 86.7％, 90.9％ and 88.8％, respectively. No pneumothorax, hemoptysis or other serious complications were found in patients. Conclusion Virtual bronchoscopic navigation, endobronchial ultrasonography with a guide sheath for solitary pulmonary nodules by transbronchial lung biopsy can improve the diagnostic rate of solitary pulmonary nodules.
ABSTRACT
Objective To explore characteristics of sleep structure and the correlation with cognitive function in cerebral infarction combined with obstructive sleep apnea hypopnea syndrome (CI-OSAHS).Methods The patients with CI-OSAHS and OSAHS in Department of Neurology and Breathing Sleep Monitoring Room of Tianjin Medical University General Hospital from December 2009 till March 2011 were collected All the patients completed polysomography(PSG).Sixty patients were selected and divided into 3 groups based on PSG.These 3 groups were combined group 20 persons (CI-OSAHS),OSAHS group 20persons (OSAHS) and control group 20 persons (without cerebral infarction obstructive sleep apnea hypopnea syndrome).All the patients completed image examinations ( CT and MRI ) evaluation of the cognitive function by Mini-Mental State Examination(MMSE) and Montreal Cognitive Assessment(MoCA).Results Sleep structure:the awake time,non-rapid eye movement sleep (NREM) 1,NREM 2 and NREM periods in combined group and OSAHS group were significantly longer,the NREM3 + 4 and rapid eye movement(REM) periods were shorter than the control group.The NREM and NREM 1 periods in combined group were longer,the NREM 3 +4 and REM periods were shorter than the OSAHS group.The correlation analysis of cognitive function and breathing disorders and low oxygen related index:there was negative correlation between the total scores of cognitive function (MMSE and MoCA)and apnea hyponea index,oxygen desaturation index (ODI) ( MMSE r =-0.450,-0.671,MoCA r =-0.486,- 0.494,all P ＜0.05) while,was positive correlation between them and noctumal average hypoxemia and minimum hypoxemia ( MMSE r =0.477,0.485,MoCA r =0.507,0.482,all P ＜0.05) in the OSAHS group.There was negative correlation between ODI,arousal index and the total scores of MoCA in the combined group (MoCA r=-0.463,0.480,both P＜0.05),there was correlation between the total scores of MMSE and the other sleep parameters,but,there was no difference in statistics.The correlation analysis of cognitive function and sleep stages:There was positive correlation between the total scores of cognitive function ( MMSE and MoCA) and the NREM 3 + 4 periods ( r =0.521,0.474,both P ＜ 0.05 ) while,there was negative correlation between the total scores of MMSE and the N REM 1 + 2 periods (r =-0.458,P ＜ 0.05 )in the OSAHS group.There was positive correlation between the REM period and the total scores of MoCA (r =0.472,P ＜ 0.05 ).There was correlation between the total scores of MMSE and the sleep structure,but,there was no difference in statistics in combined group.Conclusions Patients with OSAHS have obvious sleep structure disorder.The awake time and light sleep periods are significantly longer than the control group,while,the deep sleep and REM periods are significantly shorter than the control group.The NREM 1 of the patients with CI-OSAHS is longer than the patients with OSAHS.The higher the AHI,the lower the night blood oxygen,the more obvious cognitive dysfunction The longer the awake time,the longer the light sleep,the shorter the deep sleep and REM periods,the more serious cognitive dysfunction.The correlation between the cognitive impairment and low oxygen is more apparent than sleep structure.There is apparent correlation among the total scores of MoCA,the degree of hypoxia and sleep structure in the patients with CI-OSAHS.The total scores of MoCA are more sensitivity than MMSE in mild vascular cognitive impairment.
ABSTRACT
This paper summarize the perioperative nursing of 11 patients with vaginal reconstruction using autologous buccal micro-mucosa. The preoperatively psychological nursing,meticulous specialist care and oral care,as well as postoperatively diet instruction,oral care,vaginal care,and serf-care instruction before discharge are the key points to reduce postoperative compli-cations and increase the success rate of surgery.
