Objective To investigate the impact factors for temperature of cornea(TOC) and analyse the relationship between TOC and evaporative dry eye. Methods Two hundred and fifty-seven patients(405 eyes) with normal lacrimal secretion received dry eye tests.Patients were divided into positive group and negative group according to the results,and were randomly subdivided into 4 groups with different environment temperature(T) and relative humidity(RH).For all eyes,TOC,body surface temperature(TBS) of forehead and center corneal thickness(CCT) were measured right after blinking.The impact factors for TOC and the differences in TOC between positive group and negative group were analysed.Results TOC was positively correlated with TBS(r=0.89),T(r=0.75) and RH(r=0.60)(P

The growth-propagation and decolorization-degradation systems for the model dy e Biebrich Scarlet by Trametes hirsuta were established preliminar ily. It was showed that 30℃ and the static culture were better; the effects of compo nents in culture media on the efficiencies of decolorization and degradation wer e not significant; considering the convenience of observing the changes of dye c o lors and shortenig the culture period, the potato liquid medium had the advantag e of others as a preferable medium for reaction systems of Trametes hirsuta . The decolorization and degradation of all dyes Biebrich Scarlet and Direct Deep Blu e L-3RB, Reactive Blue X-BR, Basic Violet 5BN, and Methylene Blue by Tramete s hirsuta were better.

OBJECTIVE To investigate the significance of Epworth sleepiness scale(ESS)and modified Epworth sleepiness scale(MESS),and evaluate the feasibility of MESS in assessment of obstructive sleep apnea hypopnea syndrome(OSAHS).METHODS The ESS and MESS of 232 patients with OSAHS was recorded in their first visiting.The scores of ESS and MESS were analyzed with the parameters of polysomnography(PSG). RESULTS Both ESS and MESS can reflect the degree of sleepiness and anoxemia in OSAHS patients,but the MESS was more efficient than ESS.The difference of MESS score between normal group and severe OSAHS group was greater than that of ESS score.CONCLUSION MESS is concerned the living habit of Chinese,and can partly reflect the station of patient with OSAHS.MESS can also be a primary screening method for suspected patients with severe OSAHS.

Objective To explore the clinical performance and related factors of perimenopausal syndrome,cognition and demand for perimenopausal knowledge in community-dwelling women.Methods During June 2009 to December 2011,a cross-section survey of perimenopausal symptoms as well as cognition and demand for perimenopausal knowledge was conducted in 1546 women aged 45 to 65 years in Shanghai Changfeng Community.Results The average menopausal age of this population was (49.5 ±3.7) years.The total prevalence of perimenopausal syndrome was 75.7％ (n =1094) and 81.4％,76.5％,65.4％ in women with primary school,middle school and college education background respectively (P=0.007).Sexual disorders (80.8％),hot flushes & sweating (64.7％) and fatigue (55.8％) were the most common symptoms of perimenopause.The most serious symptoms affecting daily lives included urinary symptoms,unsatisfactory sexual life and hot flushes & sweating.And 391 (27.1％),238 (16.5％),285 (19.8％) and 296 (20.5％) women did not know the concept of perimenopausal syndrome,possible symptoms,health measures or symptoms requiring medical attention.The common methods of acquiring the knowledge of perimenopause were communicating with peers (458,31.7％),consulting professionals (364,25.2％) and searching health care information (225,17.6％).Conclusions In women,the prevalence of perimenopausal syndrome remains quite high.And a majority of them lack a sufficient knowledge of perimenopause and need professional guidance.

Objective To explore the treatment of children with EB virus infection accompanied by facial paralysis. Method The clinical data of a child with EB virus infection accompanied by facial paralysis was analyzed retrospectively, and the related literature were reviewed. Results A 2-year-old boy was admitted to hospital due to fever and mouth askew for 4 days. After admission, he was confirmed to have EB virus infection and viremia by serology and polymerase chain reaction, and then treated with acyclovir. The symptoms of facial paralysis and EB viremia disappeared completely 14 days after antiviral treatment. There was no recurrence in the short-term follow-up. Interestingly, the literature analysis shows that there is still limited evidence for the antiviral treatment by acyclovir in children with acute infection of EB virus associated with facial paralysis. Conclusion Antiviral treatment may be beneficial to EB viremia with facial paralysis.

Purpose:To study the clinical significance of CD44 level in tumor cells of esophageal carcinoma patients. Methods:Sixty-five esophageal carcinoma cases were examined to observe the CD44 expression rate in tumor cells and nor- mal mucosal cells by flow cytometry.These data were clinicopathologically analyzed and compared with statistical methods. Results:The CD44 expression rate in tumors cells of esophageal carcinoma was obviously higher than that in normal mucosal cells (P

Objective To investigate the relationship of gene polymorphisms of angiotensin eonvertion enzyme (ACE), aldosterone synthase (CYP11B2)and α-adducin with subclinical renal lesion. Methods I/D polymorphism of ACE gene, -344T/C polymorphism of CYP11B2 gene and 460G/T polymorphism of α-adduein gene were detected by polymerase chain reaction (PCR) and restrictive fragment length polymorphism(RFLP) in 604 normotensive subjects and 1081 primary hypertensive patients whose creatinine (Cr) were less than 2mg/L. The primary hypertensive and normotensive subjects were divided respectively into normal group (Ccr≥60ml/min) and subclinical renal lesion (Ccr＜60 ml/min) group, according to creatinine clearance rate (Ccr) calculated by Cockcroft-Gault equation. Results ANOVA, contingency X2 and partition of chi-square were selected. The frequencies of different genotypes of ACE, CYP11B2, and α-adducin were in agreement with Hardy-Weinberg equilibrium in our study. Normal renal function group (A group, n=512) and subclinical renal lesion group (B group, n=92) in normotensive subjects, and normal renal function group (C group, n=828) and subclinical renal lesion group (D group, n=252) in hypertensive patients were compared. The patients in B and D groups were older than those in A and C groups (P<0.01). But there were no significant differences in the age between B and D groups, and between A and C groups. The frequency of ACE-DD genotype in D group was the highest (22.6%) among four groups and the frequency of α-adducin-TT genotype in A group was the lowest (13.3%) among four groups (all P<0.01). The differences of genotype frequencies of ACE and α-adducin genes among other three groups were not significant. No significant difference was found in frequencies of genotypes of CYP11B2 among four groups. Conclusions Subclinical renal lesion is increased with the aging. ACE-DD genotype is related with hypertension and subclinical renal lesion, while α-adducin-TT genotype is related with hypertension and subclinical renal lesion. Association between the genotypes of CYP11B2 and subclinical renal lesion is not found.

Objective To investigate the accuracy for absolute quantification of brain creatine (Cr) concentration using long time echo (TE) point resolved spectroscopy (PRESS) sequence performed with an external standard and postprocessed with the linear combination of model spectra (LCModel).Methods Ten swine (3.1±0.6 kg) and an external standard phantom containing detectable compounds of known concentration were investigated in this study by using 1.5 T GE Signa scanner and a standard head coil. The single-voxel proton magnetic resonance spectroscopy (1H-MRS) data were acquired from the two ROIs (2 cm×2 cm×2 cm) placed in swine brain and external standard solution using PRESS sequence with TE 135 ms,TR 1500 ms,and 128 scan averages.The in vivo quantification of Cr was accomplished by LCModel.After 1H-MRS examination,each animal was sacrificed immediately.In vitro Cr concentration was analyzed by high performance liquid chromatography (HPLC).Results In the 1H-MRS group,the Cr concentration was (9.37±0.14)mmol/kg.In the HPLC group,the Cr concentration was (8.91±0.13)mmol/kg.Good agreement was obtained between these two methods (t=9.038,P=0.491).Conclusion The long echo time PRESS sequence performed with an external standard and processed with LCModel iS proven to be an accurate technique to detect the in vivo brain Cr concentration.
