Objective To explore the differences of memory functions and objective sleep parameters and their correlations in patients with insomnia disorder in different subtypes.Methods Eightynine patients with insomnia disorder,including 11 patients with difficulty initiating sleep(DIS),20 patients with early morning awakening(EMA),20 patients with difficulty maintaining sleep (DMS) and 38 patients with mixed sleep symptoms(MS) were enrolled between August 2012 and February 2014 in the Memory and Sleep Disorders Clinic of the First Affiliated Hospital of Anhui Medical University.Memory functions,including objective memory,spatial memory,working memory and reference memory were detected with nine boxes maze,and objective sleep profiles were assessed using polysomnography.Results The error numbers of spatial(H =15.404,P =0.002) and working (H =10.126,P =0.018) memories were significantly different among the 4 subtypes of patients,with more errors of spatial and working memory in the EMA (6.00 (5.00,8.00),5.00 (4.00,6.00)) and MS (5.00 (3.75,7.25),5.00 (2.75,7.00)) groups compared with the DMS (2.50 (2.00,4.00),2.00 (1.00,4.00)) group (tspstial =3.938,3.428;t =2.803,2.840;all P < 0.05).Sleep efficiency(H =7.929,P =0.048),REM sleep time(F =2.840,P =0.043) and the percentage of REM sleep time on total sleep time (REM%;H =7.913,P =0.048) were also significantly different among the 4 subtypes of patients,with lower sleep efficiency in the MS(69.7% (50.5%,78.7%)) group compared with the EMA (81.0% (64.8%,86.4%)) and DMS (80.2% (62.6%,88.9%)) groups (t =2.242,2.352;all P < 0.05),less REM sleep time (min) and REM% in the EMA(61.6 ±27.1,16.9% (13.1%,21.9%)) and MS(56.9 ±31.4,16.9% (11.5%,21.2%)) groups compared with the DMS (80.9 ± 32.7,22.3% (18.5%,25.5%)) group (qREM time =3.791,5.397;tREM% =2.513,2.612;all P <0.05).The error numbers of working memory and spatial memory negatively correlated with the REM sleep time (r =-0.387,-0.348;all P < 0.05) and REM% (r =-0.350,-0.354;all P < 0.05).Conclusions There are discrepancies in the spatial and working memories and subtle differences in the objective sleep parameters among the patients with different subtypes of insomnia disorder.The worse memories in insomnia disorder patients might be associated with the decreased REM sleep.

OBJECTIVE:
To explore the ways of quantitative and objective evaluation for analyzing the multiple influence factors on middle ear function in the patients with primarily diagnosed NPC, and to analyze the influence factors of middle ear function in the patients with primarily diagnosed nasopharyngeal carcinoma (NPC).
METHOD:
Three hundred and twenty cases (320 ears) of primarily diagnosed NPC patients were examinated with electric otoscope, acoustic immittance measurement, pure tone audiometry, nasopharynx and middle ear CT or MRI scanning, eustachian tube function examination, and electronic nasopharyngoscope. A series of quantitative methods, as the influence factors including T stage, clinical stage, location, diffusion type and form of tumor, eustachian tube function, pharynx mouth shape, imaging extension (nasal, skull base, pharyngeal recess, parapharyngeal space, tensor veli palatini muscle, levator veli palatini and so on), were used to evaluate the middle ear function. SPSS 13.0 was used to anlyze the single and multiple factors in statistics.
RESULT:
T stage, clinical stage, location, diffusion type, and form of tumor, pharynx mouth shape, imaging extension (nasal, skull base, pharyngeal recess, parapharyngeal space, tensor veli palatini muscle, levator veli palatini) were the single influence factors on the function of middle ear in primarily diagnosed NPC patients. The gender, age, pathological types, N staging and M staging of NPC patients primarily diagnosed had no effect on middle ear function. The multple factors analysis showed that T stage, tumor location, the function of eustachian tube, tensor veli palatini muscle invasion, and skull base invasion were independent factor of affecting the middle ear function on primarily diagnosed NPC patients.
CONCLUSION
In this study, the influence factors of middle ear function with primarily diagnosed NPC were related to T stage, location of tumor, the function of eustachian tube, tensor veli palatini muscle invasion, skull base invasion, otitis media and quantitative criteria. The way of quantitative analysis could be used to evaluate objectively the middle ear function in patients with primarily diagnosed NPC.

OBJECTIVETo explore the spatial and temporal distributions of animal plague in Junggar Basin natural plague focus.
METHODSData regarding plague antibody (F1) in serum of Great Gerbil (Rhombomys opimus, R. opimus) which were collected from 2005 to 2012 in Junggar Basin and analyzed. The changing rates on the positivity of F1 that appeared spatially and temporally were also analyzed.
RESULTSA total of 4 825 R. opimus serum samples were collected in 13 administrative regions in Junggar Basin.
RESULTSshowed that plague R. opimus existed in two areas-Gurbantonggut desert in the eastern-center and the clay desert of western Junggar Basin. However, in these two areas, the intensity of animal plague prevalence was different. In the former region where Yesinia pestis positive serum was detected from R. opimus, the detected rate of R. opimus was 8.39%. However, in the latter areas, the average positive rate was 1.56%. The changing trends of R. opimus plague prevalence were also varied annually. In the western Junggar Basin, the trend showed a slowly downward profile. The serum positive rate of R. opimus for Yesinia pestis decreased, from 7.59% in 2005 to 0.61% in 2008, and appeared as a resting state that none of the positive sample could be found since then. However, in the eastern-center Junggar Basin area-also named as Gurbantonggut desert which had been divided into 3 segments(western, central and eastern, according to related geographical characteristics), the changing trends of animal plague seemed quite complex. In the western segment, the animal plague had two epidemic peaks-in 2006 and 2010, with the interval of 4 years, with the higher peak of all the three geographic segments as 45.65% in 2010 and the positive serum of R. opimus for plague could be detected each year from 2006 to 2012. However, there were 3 epidemic peaks in the same period in the central and eastern segments. In the central segment, the peaks appeared in 2006, 2009 and 2011, with the intervals as 2.5 years and the average positive rate 8.92% was seen the lowest in Gurbantonggut desert. In the eastern segment, the first 2 peaks appeared the same season as in the central segment, but the third peak appeared in 2012, with the peak interval as 3 years. The positive rate of R. opimus for plague was also different in seasons, with the positive rate higher in autumn than in spring. These findings showed that the animal plague could be continuously prevalent from spring to autumn in the natural foci of plague in the Junggar Basin.
CONCLUSIONBoth geographical and temporal fluctuations of animal plague existed in the natural foci of Junggar Basin which was also named as geographical heterogeneity. Consequently, animal plague could be divided into two areas-the clay plains desert in the western and the Gurbantonggut desert in the eastern-center Junggar Basin.
