Objective: To observe the clinical effect of Quyu-Huatan decoction combined with noninvasive positive pressure ventilation in treatment with moderate to severe obstructive sleep apnea hypopnea syndrome with phlegm dampness type. Methods: A total of 64 patients with moderate to severe obstructive sleep apnea hypopnea syndrome with phlegm dampness type were divided into observation group and control group according to the random number table method, with 32 cases in each group. The control group received routine clinical treatment combined with noninvasive positive pressure ventilation, while the observation group was treated with Quyu-Huatan decoction on the basis of the control group. After 4 weeks of treatment, the polysomnography (PSG) index (the apnea hypopnea index, AHI, the Oxygen saturation, SaO₂, the pulse pressure, PP, the longest apnea time), the degree of lethargy (Epworth sleepiness scale, ESS), the quality of sleep (Pittsburgh sleep quality index, PSQI) and the quality of life (Calgary mass index of life quality index, SAQLI) before and after the treatment of two groups were observed, and the clinical effect was compared. Results: The total effective rate of the observation group was 87.5% (28/32), which was significantly higher than that 68.8% (22/32) of the control group (Z=-3.187, P=0.000). After treatment, the AHI (8.59 ± 0.93 times/h vs. 18.62 ± 2.44 times/h, t=5.735), the PP (35.96 ± 4.02 mmHg vs. 43.33 ± 4.70 mmHg, t=5.083) and the longest apnea time (11.93 ± 1.86 s vs. 17.94 ± 2.43 s, t=4.863) of the observation group were significant lower than those of the control group (P<0.05), while the SaO2 content (93.07% ± 10.03% vs. 82.36% ± 9.37%, t=5.812) of the observation group were significant higher than those of the control group (P<0.05). After treatment, the ESS (5.33 ± 0.33 vs. 8.73 ± 0.96, t=4.682) and the PSQI (2.25 ± 0.31 vs. 5.68 ± 0.77, t=4.872) of the observation group were significant lower than those of the control group (P<0.05), and the SAQLI (6.12 ± 0.59 vs. 4.36 ± 0.53, t=4.631) of the observation group were significant higher than those of the control group (P<0.05). Conclusions The application of Quyu-Huatan decoction combined with noninvasive positive pressure ventilation in treatment with moderate to severe obstructive sleep apnea hypopnea syndrome with phlegm dampness type can improve sleep disordered breathing, relieve drowsiness, and improve sleep quality and quality of life.

Objective To analyse the influencing factors diagnosed by the virtual touch tissue quantification (VTQ) technology on the hardness of papillary thyroid carcinoma (PTC).Methods From May 2011 to March 2014,a total of 266 PTCs in 266 patients confirmed by pathology were enrolled in Shanghai Tenth People's Hospital.The shear wave velocity (SWV) values of PTCs were measured by VTQ.PTCs were divided into 2 groups including SWV ≥ 2.87 rn/s and SWV ＜ 2.87 rn/s.The x2 test was used to compare the basic clinical data,ultrasound features and immunohistochemical results between 2 groups.The influencing factors of SWV values of PTCs were analyzed by forward stepwise Logistic regression analysis.Results Of the 266 PTCs,183 were SWV ≥ 2.87 m/s and 83 were SWV ＜ 2.87 m/s.The x2 test showed that the ultrasound features of PTCs such as single or multiple,with or without central lymph node metastasis,location,size,shape,with or without posterior acoustic attenuation,with or without calcification,with or without capsule invasion,whether close to the trachea between the 2 groups were significant different (x2=4.233,4.740,9.910,4.988,4.416,4.737,7.154,8.559,all P ＜ 0.05 or 0.01).Logistic regression analysis demonstrated that nodules were single or multiple,location,with or without posterior acoustic attenuation,with or without calcification,whether close to the trachea were influencing factors of SWV value of PTCs.The regression equation was defined as Y=-2.507 + 0.670X1 (nodules were single or multiple) + 0.800X3 (location of nodules) + 0.851X6 (with or without posterior acoustic attenuation) + 0.628X7 (with or without calcification) + 1.106X9 (whether close to the trachea).Conclusions Multiple nodules,central lymph node metastasis,located isthmus,nodules size ＞ 10 mm,irregular shape,posterior acoustic attenuation,calcification,capsule invasion,close to the trachea were correlated with the diagnosis of PTC by VTQ technology.The more characteristics of nodules appeared,such as multiple nodules,located isthmus,posterior acoustic attenuation,calcification,close to the trachea,the harder PTCs were.
