Objective To explore the clinical significance of two new indexes including approximate entropy of oxygen saturation (SpO2ApEn) and saturation impairment time index (SITi) in assessing the severity of hypoxemia in obstructive sleep apnea hypopnea syndrome (OSAHS) patients.In addition,to investigate the correlation betewwn new indexes and other parameters.Methods The six hour polysomnography (PSG) of 500 patients with OSAHS and snorers in our hospital was retrospectively analyzed.According to the level of apnea hypopnea index (AHI),subjects were divided into four subgroups,namely 113 healthy controls,121 mild OSAHS,118 moderate OSAHS,and 148 severe OSAHA patients.SpO2 ApEn and SITi values among the four groups were compared.the correlations between SpO2 ApEn,SITi and other parameters were analyzed,including AHI,oxygen desaturation index (ODI),the lowest oxygen saturation(LSpO2) and the duration of oxygen saturation lower than 90％ (T ＜ 90％).Next,taking AHI as the gold standard,the significance of SpO2ApEn and SITi in assessing the severity of hypoxemia in OSAHS patients was explored by ROC curve analysis.Results SpO2ApEn and SITi between two each groups were significantly different (P ＜ 0.001) and increased synchronously with AHI.Spearman correlation analysis showed that SpO2ApEn and SITi had a good correlation with AHI (correlation coefficient r =0.765,r =0.678,P ＜ 0.O1).SpO2ApEn and SITi also had a good correlation with ODI,LSpO2and T ＜ 90％.According to the ROC analysis,the Boundary values of SpO2ApEn for mild,moderate and severe OSAHS patients were 16.70,17.81,and 20.03,respectively,and the corresponding SITi values were 3.685,4.055,and 4.445.Conclusion In this study,SpO2ApEn and SITi increased synchronously with AHI,SpO2ApEn and SITi had good correlations with AHI,ODI,LSpO2and T ＜90％.SpO2ApEn and SITi have important clinical significance for assessment of hypoxia severity in OSAHS patients.

Objective To evaluate the relationship between cranial CT characteristics and prognosis after first-ever primary supratentorial intracerebral hemorrhage (PSICH). Methods The data of clinic and CT in patients with first-ever PSICH were registered prospectively and followed up for 6 months. The relationship between the prognosis and the clinic data was analyzed using univariate and multivariate Logistical regression analysis.Results (1) The volume of hematoma was an independent CT predictor of death at 1st, 3rd and 6th month. (2) Both the volume of hematoma and secondary ventricular hemorrhage were independent CT predictors of death/disability at 6th month.Conclusions (1)The volume of hematoma can be used to predict death in patients with PSICH.(2)The volume of hematoma and secondary ventricular hemorrhage can be used to predict the death/disability rate of PSICH.

Objective To analyze the effect of different medical insurance payments on medical expenses so as to provide some suggestions for Guangdong Provincial Department of Offsite Medical Insurance Administration in its future policy-making.Methods An statistic analysis was conducted of medical expenses among patients who chose different medical insurance payments and their average length of stay.Results Medical expenses and average length of stay were statistically different among patients who chose different payments.Conclusion The medicare reimbursement′s inclusion of prevention and diagnosis should be recommended to establish a flexible referral system, reinforce the payments reform and increase the efficiency of social security funds.

Information of the acupuncture treatment ofdepression in 93 ancient books has been made statistics with computer Results showed that Heart Meridian, Pericardium Meridian, Bladder Meridian, Governor Vessel,Conception Vessel, Spleen Meridian and Stomach Meridian have been used frequently; as to areas, the medi al aspect of upper limbs, head and face, medial aspect of legs, upper back, chest and abdomen have been mostly selected; as to treatment methods, needling,moxibustion and blood-letting therapies have been utilized.

The data concerning the treatment of diarrhea by acupuncture in 62 ancient books are computerized and thus show that the ancient acupuncturists primarily used the acupoints of the conception vessel, stomach meridian, bladder meridian, and the foot yin meridians.As to the location, the acupoints on the abdomen, back,exterior side of leg and the hands and feet are used. The common techniques are moxibustion, hot compression,needling, blood letting, navel application and so on.
