OBJECTIVETo observe the effect of magnesium sulfate, Nifedipine Tablet (NT) combined Salvia Injection (SI) on endothelin-1 (ET-1), nitric oxide (NO), thromboxane A2(TXA2), prostacyclin I2(PG2), and hemorheology of preeclampsia patients.
METHODSTotally 704 preeclampsia patients were randomly assigned to the treatment group and the control group, 352 cases in each group. All patients were treated with magnesium sulfate combined NT (on the first day: slow intravenous injection of magnesium sulfate 5 g + intravenous dripping of magnesium sulfate injection 10 g + oral administration of NT 30 mg; on the second and third day, intravenous dripping of magnesium sulfate injection 10 g + oral administration of NT 30 mg), while those in the treatment group were dripped with SI additionally at 20 mL per day for 3 consecutive days. Before and after treatment plasma levels of endothelin-1 (ET-1), nitric oxide (NO), TXA2, PGi2, and hemorheology indicators [such as high blood viscosity (HBV), low blood viscosity (LBV), plasma viscosity (PV), erythrocyte rigidity index (ERI), fibrinogen (FIB)] of two groups were detected.
RESULTSCompared with the same group before treatment, serum levels of ET-1, TXA2, HBV, LBV, PV, ERI, and FIB decreased in the two groups after treatment (P <0. 05), but levels of NO and PG2 increased (P <0. 05). Compared with the control group in the same period, levels of ET-1, TXA2, HBV, LBV, PV, ERI, and FIB decreased in the treatment group after treatment (P <0. 05), but levels of NO and PGI2 increased (P <0. 05).
CONCLUSIONMagnesium sulfate, NT combined SI could effectively regulate the balance of ET-1/NO and TXA2/PGI2, and improve hemorheology of preeclampsia patients.

OBJECTIVETo explore the diagnostic value of pulse transit time (PTT) in children with sleep disordered breathing(SDB).
METHODSForty eight randomly selected snorers (2 - 13 years) with SDB were examined by PSG and PTT in the same time. Data obtained were analyzed by different technicians respectively. Statistics and analysis of the data were performed.
RESULTSApnea hypopnea index (AHI), obstructive apnea index (OAI), the lowest oxygen and micro-arousal index were obtained by PSG and PTT. The results was described as M [25 percentile; 75 percentile]: 4.9[1.3;10.1], 4.6[1.5;11.8]; 1.2[0.7;4.9], 1.3[0.6;5.0]; 0.93[0.85;0.95], 0.93[0.84;0.95]; 14.5[12.6;16.4], 26.0[17.4;30.6]. The difference of AHI, OAI, and the lowest oxygen were not significant (P > 0.05), while the PTT arousal index detection rate was higher than PSG (Z = -5.19, P < 0.01). There was no significant difference in the diagnosis of obstructive sleep apnea-hypopnea syndrome (OSAHS) and determination of degree of patient's condition (P > 0.05). PTT could identify upper airway resistance syndrome in children without OASHS.
CONCLUSIONSBoth methods can be used to diagnose SDB. However, PTT is easy to use and suitable for the diagnosis of SDB in children, especially for UARS.

OBJECTIVETo analyze the similarities and differences of the clinical manifestations between the children with upper airway resistance syndrome (UARS) and obstructive sleep apnea-hypopnea syndrome (OSAHS), and to explore the clinical features and characteristics of sleep respiratory parameters.
METHODSUsing the double-blind method, all children were diagnosed as UARS or OSAHS through the polysomnography test and the results of all children were analyzed by a sleep technician and an otolaryngologist. Another ENT doctor recorded their clinical and physical examination in detail.
RESULTSPolysomnography showed that the apnea-hypopnea index (AHI) and the lowest oxygen in 253 children with OSAHS were 3.60[2.00;7.55] times/h and 0.90[0.85;0.91], and were 0.90[0.50;1.10] times/h and 0.95[0.92;0.96] in 102 children with UARS, the difference of the two groups by rank test was statistically significant. The proportion of UARS and OSAHS was more common during preschool period than during school-age period. The chief complaint in two groups was sleep snoring, and the main symptoms were sleep restless, attention deficit/hyperactivity and breath with mouth open. The incidence rate of above symptoms were as follows, 94.1%, 72.5%, 62.7% and 37.3% in children with UARS, 92.9%, 78.7%, 57.7% and 45.5% in children with OSAHS. The difference was not significant by chi-square test (P>0.05). Tonsil and adenoid hypertrophy were also observed in the two groups, the difference was not significant (chi2 = 0.27, P= 0.87). However, the children with OSAHS were more apt to have the sleep apnea than with UARS, the difference was statistically significant (chi2 = 34.07, P<0.001).
CONCLUSIONSThe clinical manifestations of two groups are similar, the difference between UARS and OSAHS can not be determined by the patient's clinical performance. Sleep apnea can be more easily observed in children with OSAHS than that in UARS, the final diagnosis is based on polysomnography.

The inclusion complex of cordycepin ( COR ) with hydroxypropyl-β-cyclodextrin ( HPβCD ) was prepared by the method of saturated solution. The inclusion of HPβCD with COR in aqueous solution was studied by UV-vis spectroscopy, and the inclusion ratio of COR/HPβCD complex was determined with the Job plots. The COR/HPβCD complex was characterized and determined by means of 1 H NMR and 2D NMR, differential scanning calorimetry ( DSC ) , thermogravimetric analysis ( TG ) , X-ray diffraction ( XRD ) , Fourier transform infrared spectroscopy ( FTIR) and scanning electron microscope ( SEM) . The results showed that the COR/HPβCD complex ratio was 1:1 and the water solubility and stability of COR were obviously increased in the inclusion complex with HPβCD. The COR/HPβCD complex will be potentially useful for its medical application.
