Noninvasive continuous positive airway pressure (CPAP) for the ventilation treatment of obstructive sleep apnea-hypopnea syndrome (OSAHS) is the first-line treatment method. This article aims to describe the effect of surgical operation especially for the UPPP in the individualized comprehensive treatment of OSAHS and the importance of surgical technique. Lower compliance is the bottleneck of CPAP therapy in clinical application, for the OSAHS patients with treatment failure in CPAP or those cannot accept CPAP therapy, when with no other ideal instrument therapeutics, accurate diagnosis of position in airway obstruction with an adequate surgical operation is the treatment,of choice. Surgical operation is particularly important either as a fore-lying means to improve the CPAP treatment compliance or as an independence treatment method of OSAHS. The pharyngeal cavity is the most common obstructive plane in patients with OSAHS. The operation of traditional UPPP aiming at the expansion of pharyngeal cavity is the classics surgery to solve obstruction in this plane, the lower operation effective rate is the main reason of restriction in its development. How to improve the effective rate of surgical treatment of OSAHS is our surgical goal. The effective rate of surgical operation treatment in OSAHS rely on the following sides: to follow the OSAHS individualized comprehensive treatment principle, reasonable choice of surgical operation indication, the precise localization diagnosis of upper airway obstruction, adequate surgical operation and skilled surgical techniques.

To investigate the effects of the free radical, 1,1-Diphenyl-2-picylhydrazyl, on cochlear blood flow, 20 guinea pigs were divided into 3 groups at random, 6 for control group, 6 for 1 mmol/L group and 8 for 0.1 mmol/L group. 2 microliters vehicle or drugs were dropped into round window membrane (RWM). Cochlear microcirculation was monitored by laser Doppler flowmeter (LDF), and mean arterial blood flow (MABP), which was transferred by pressure conductor sensor and preamplifier, was simultaneously recorded on the computer. Our results showed that MABP was stable throughout the experiment. Cochlear blood flow (CBF) increased by 10.32% (P < 0.05) in 1 mmol/L group, and decreased by 4.89% in 0.1 mmol/L group (P < 0.05). In control group cochlear microcirculation showed no significant changes. It is concluded that DPPH exerted effects on cochlear microcirculation.

Objective To study dynamic response of serum lipid after fat meal in old persons with fasting TG≤1 70 mmol/L. Methods Using fat meal of 63 9 g/m 2 body surface area, TG, TC, HDL C and LDL C of both elderly and control groups in fasting status and 2, 4, 6 and 8 h after fat meal were determined. Results The TG value after fat meal was significantly higher than that in fasting status( P 0.05). Conclusions The expurgation of triglycerides is delayed in elderly people, meaning that the capacity for fat removal is decreased, and it is possibly the main cause of TG increase in the elderly.

Objective To explore the related factors influencing the prognosis of children with Tourette syndrome ( TS) . Methods We collected 420 outpatient cases of TS children in the department of pediatrics of Guangdong Provincial Hospital of Traditional Chinese Medicine from January of 2007 to October of 2010 as the research objects. Using the unified survey questionnaire, we observed the influencing factors of TS prognosis such as sex, onset age, mother’s pregnancy situation, the perinatal period, partiality for food intake, family relationship, the first symptom, the severity of disease, underlying diseases, comorbidities ( such as attention deficit hyperactivity disorder, anxiety disorder, and obsessive-compulsive disorder) , family history of psychiatric or neurological diseases, trace elements levels, electroencephalogram (EEG), antistreptolycin O (ASO), course of disease, and maintenance treatment. The related factors of prognosis was analyzed with single factor and multiple factors Logistic regression analysis. Results Among the 420 cases of TS children, 396 cases were included into the final analysis, 24 were lost and the follow-up lost rate was 5.7%. The remission rate of TS was 78.3%, and the uncured rate was 21.7%. The results of preliminary screening of the influencing factors by single factor Logistic analysis showed that the related influencing factors for TS prognosis were 12, and they were course of diseases, abnormal birth history, father’s education level, mother’s education level, upbringing methods, family history of psychiatric or neurological diseases, underlying disease history, comorbidities history, abnormal ASO, the severity of disease, the frequency of disease relapse, and the medication history of western medicine (P<0.05) . And then the obtained 12 factors were analyzed by the multiple fac tors Lo gistic regression analysis, the results showed that upbringing methods, comorbidities history, the severity of disease, and the frequency of disease relapse were correlated with TS prognosis ( P < 0.05) . Conclusion TS children will have poor prognosis when their parents spoil, indiscipline, beat and scold, and dictate them, or when the children have severe illness state, frequent recurrence of the disease, and the history of comorbidities ( atten tion deficit hyperactivity disorder, anxiety disorder, obsessive-compulsive disorder, etc.) .

Objective To investigate the effect of deltaNp63(ΔNp63) silencing on the proliferation of pancreatic cancer PANC1 cells.Methods ΔNp63 mRNA level in 23 pairs of pancreatic cancer and adjacent tissue specimen was detected by real-time PCR, andΔNp63 protein in human normal pancreatic ductal cell line HPDE6-C7 and pancreatic cancer cell line PANC1, CFPAC1 and BXPC3 was detected by Western blot.
