Chinese traditional health concepts are rooted in traditional culture,absorb the essence of various health concepts from Confucianism,Buddhism,Daoism and other schools,and form the unique and rich connotation health concepts.These simple concepts of health are historical origin and precious wealth of modem health concepts.Through analyzing the health outlook in traditional books and quoting some thoughts about physical health,mental health,human and social harmony,and ethical health,this paper excavated the character and limitation of traditional health concepts,and explored the enlightenment to modern health ideas.

Objective To find the normal range and features for auditory brainstem responses(ABR)of infants within six months,and the basic parameters for identifying the hearing impaired infants.Methods May 2006 to May 2008,60 normal infants and 20 normal adults received the ABR tests.The infants were divided into three groups:group A(6 weeks),group B(3 months)and group C(6 months).Each group consisted of 20 infants(40 ears)and the ABR data were statistically analyzed.Results At 100 dB nHL,the waveⅠ,Ⅲ,Ⅴ latencies of ABR for 6-week infants respectively were 1.49?0.08 ms,4.42?0.16 ms and 6.61?0.25 ms,for 3-month infants,1.47?0.07 ms,4.35?0.20 ms and 6.50?0.25 ms,for 6-month infants,1.45?0.07 ms,4.17?0.15 ms and 6.32?0.22 ms.At 80 dB nHL,the waveⅠ,Ⅲ,Ⅴ latencies of ABR for 6-week infants were 1.63?0.08 ms,4.52?0.17 ms and 6.74?0.26 ms,respectively,for 3-month infants,1.64?0.11 ms,4.44?0.20 ms and 6.67?0.26 ms,for 6-month infants,1.60?0.11 ms,4.27?0.16 ms and 6.43?0.24 ms.As the intensity of stimulating signals decreased,the peak latency of ABR became more delayed.The peak latencies of Ⅲ,Ⅴ waves and interval peak latencies of Ⅰ-Ⅲ and-Ⅴ waves for the infants were more delayed than those for adults,and became shorter with the increase of the infants' ages,but they failed to reach adults' levels even for 6-month infants.However,the length of wave Ⅰ of ABR for infants of different months was close to that for adults.The thresholds of ABR for the infants of different ages were not significantly different,all being close to the values for adults.Conclusion This study has analyzed the ABR wave features for the infants of three ages and this can help to define the reference ranges for the infants and to provide the parameters for early diagnosis of hearing loss among the infants.

Objective To investigate the skin reactions induced by to pical 0.1% tretinoin and its vehicle in mice.Methods 0.1% tretinoin and its v ehicle were applied separately on mice backs,once a day for 30 days.The skin r eactions,including erythema and scaling,were observed macroscopically and meas ured by biological instruments.Results Macroscopically the skin reactions of erythema and scaling induced by topical tretinoin occurred on day 3 after applic ation,reached its peak on day 6 and disappeared on day 12,and neither erythema nor abnormal scaling appeared in spite of continuing application until day 30.The erythema value measured was enhanced significantly on day 1 after applicatio n,reached its peak on day 6,maintained until day 9 and became normal on day 11.From then to day 30,it maintained at the normal level.The scaling value measu red enhanced significantly on day 3 after application,reached its peak on day 9 and became normal on day 27.Topical application of the vehicle induced neither skin reaction nor any change of erythema and scaling value.Conclusions Topic al application of 0.1% tretinoin induces skin reaction characterized by erythema and scaling.The reaction,transient but not related to the vehicle,experience s a process of "occurrence-peak-disappearance".

Objective To analyze epidemiological characteristics of mitochondrial DNA12SrRNA A1555G mutation in Chinese populations with non-syndromic sensorineural hearing loss by the literature review and find the main actual deficiencies in course of epidemiological study.Methods From Cbmdisc and PUBMED database pulled out were all published epidemiological literatures about Chinese mtDNA12SrRNA A1555G mutation from 1996 to 2008.Reviewed were the primary data of these studies including the number of samples,demographic characteristics of the samples,mutation frequencies,interrelations between the mutation and aminoglycoside exposure and so on.Results 21 papers out of 25 were induded in this study.The patients had non-syndromic sensorineural hearing loss from 14 regions of China.A total of 3 473 were found including 230 patients with A1555G mutation and the average mutation frequency was 6.62%.The samples in each regions ranged from 72 to 802 and the reported mutation frequencies were from 0.67%-14.6%.The statistical discrepancy was significant among mutation frequencies in different regions by χ~2 test(P=0.0000).The number of patients with aminoglycoside antibiotics exposure was 739 including 100 with A1555G mutation in all literatures.The proportions in different regions were from 2.70% to 33.33% with the average of 13.53%.The average proportion was significantly higher than the mutation frequency in patients with non-syndromic sensorineural hearing loss.Conclusion Some deficiencies in epidemiological research Omutation in China included age,ethnic,and geographic bias,insufficiency of samples,inadequate randomization and so on.Researchers should focus with more efforts on the epidemiological characteristics of A1555G mutation in Chinese people.

PurposeTo evaluate the feasibility of a low-dose contrast medium protocol for 64-slice spiral CT angiography (CTA) of cerebral and carotid using a low-tube-voltage setting, and to compare the display effect of cerebral and carotid arteries by low-tube-voltage low-dose contrast medium and routine-tube-voltage routine-dose contrast medium scanning, and to assess the effect on radiation dose.Materials and MethodsEighty consecutive patients were prospectively selected to perform cerebral and carotid CTA inspection. The patients were randomly divided into control group and low dose group with 40 people in each group. The voltage in control group was 120 kV and the contrast agent was 80 ml; those in low dose group were 80 kV and 50 ml, respectively. The artery image quality was evaluated and venous interference was scored. The CT value, signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR) and radiation dose in both groups were statistically analyzed.Results The consistency of uniform in artery image quality score and venous interference score was rather high according to the assessment of two physicians (Kappa=0.782 and 0.867). There was no statistical difference in artery image quality score, venous interference score, SNR and CNR between the two groups (Z=-0.864--0.032,P>0.05). The CT value in low dose group was higher than that in control group (differences with statistical significance,t=-8.789-1.715,P<0.05). The CT dose index of volume, dose-length product and effective dose in low dose group were all signiifcantly lower than those in control group (Z=-8.888,t=78.092 and 78.350, respectively,P<0.05).Conclusion The use of low tube voltage and low contrast dose in cerebral and carotid CTA examination can result in high quality images which meets the diagnostic needs and obviously reduce radiation dosage.

Objective To explore the more effective measures for the prevention of deep vein thrombosis (DVT ) by comparing the different efficacy between the multimodal strategy and liberal measures .Methods From July 2011 to June 2013 ,medical records of 289 patients who had accepted total knee replacement (TKR) were collected .Patients were divided into two groups according to whether exploring to the multimodal strategy or liberal measures after TKR .The multimodal strategy consisted of sequentially used perioperative intermittent pneumatic compression ,intermittent pneumatic compression ,and postoperative continues femoral nerve block analgesia .Patients in group A were treated during July 2011 to June 2012 ,and accepted liberal measures for the prevention of DVT .Patients in group B were treated after June 2012 ,and accepted multimodal strategy .The data of each group were collected for statistical analysis on the following aspects :DVT occurrence rate ,DVT distribution ,age ,gender ,body mass index ,disease ,operation duration ,volume of blood loss and transfusion during operation phase ,drainage volume after TKR .Results The DVT occurrence rate of patients in group B were significantly lower than that of patients in group A (P<0 .05) .No significant difference were foun-ded in the DVT distribution between the two groups(P>0 .05) .Conclusion The multimodal strategy consisted of sequentially used perioperative intermittent pneumatic compression ,postoperative low molecular weight heparin ,and postoperative continues femoral nerve block analgesia is more effective than liberal measures for the prevention of DVT .

It is the intent of this study to simulate the performance of trans-esophageal aortic blood oxygen saturation (SeO2) monitoring by using trans-esophageal echocardiography (TEE) probe to provide an evidence for proper positioning of placing SeO2 sensor. 25 selected cardiac surgical patients were involved. After anesthesia was induced and trachea was intubated, the multiplane TEE probe was inserted into the esophagus, and the depths from the fore-tooth to the location for detecting aorta were recorded when the distances between TEE probe and aorta anterior wall were shorter than 0.5 cm, 1 cm, and longer than 1 cm, respectively. The o'clock directions of TEE probe were also recorded. The multiplane TEE probe, with its one-use pediatric SpO2 sensor attached, was inserted, and its anterior structure was examined when trans-esophagus oximetry detected high quality SpO2 signals. The results showed the beginning position of detecting aortic SpO2 signal in esophagus was mid esophagus (24.8 +/- 4.4 cm from the fore-teeth), the moving range was 5-10 cm downward, the deepest depth of detecting descending aorta was 41.4 +/- 4.7 cm from the fore-tooth, and the direction was left-posterior. And photoplethymography (PPG) wave's form was changed when SpO2 probe's anterior structure was different.

_ Objective_ To analyze the relationship between the fasting plasma glucose ( FPG ) of pre-pregnancy women and occurrence of gestational diabetes mellitus( GDM) , and to explore the value of risk evaluation of GDM by lowerling cut-point for impaired fasting glucose ( IFG ) . Methods The general clinic check information before pregnancy, the plasma glucose levels during 24-28 weeks of pregnancy and pregnancy outcomes were collected prospectively in Weifang and Zhucheng Maternal and Child Health Hospital between February 2014 and November 2014. The FPG levels of the recruited women were lower than 6. 1 mmol/L. According to the criteria for GDM of Ministry of Health (MOH)of China in 2011, and based on the results of 75 g oral glucose tolerance test, pregnant women who underwent screening for GDM were recruited and separated into normal group and GDM group. Based on the FPG levels before pregnancy and according to the recommendation as American Diabetes Association ( ADA ) suggested in 2003, recruited women with normal FPG level according to World Health Organization ( WHO) criteria (1999)were divided into 5. 6-6. 1 mmol/L and<5. 6 mmol/L groups. Results Among the child-bearing age women with FPG<6. 1 mmol/L, the incidences of GDM and macrosomia were 19. 2% and 8. 2% respectively. In the group with FPG between 5. 6 and 6. 1 mmol/L, incidences of GDM and macrosomia were 34. 2% and 4. 7%respectively. While in the group with FPG<5. 6 mmol/L, incidences of GDM and macrosomia were 13. 2% and 15. 3% respectively. The risks of GDM and macrosomia were increased by 2. 6 times and 3. 3 times respectively in group with FPG between 5. 6 and 6. 1 mmol/L (34. 5%), compared with that in group with FPG<5. 6 mmol/L(P<0. 01). Age, FPG, and body mass index before pregnancy in GDM group were significantly higher than those in normal group. The receiver operating characteristic curves in predicting GDM showed that the optimum cut-points for age, FPG, and body mass index were 30 years old, 5. 55 mmol/L, and 23. 7 kg/m2 respectively. Conclusions The risk of GDM in childbearing aged women with FPG from 5. 55 to 6. 10 mmol/L was markedly increased. The optimum cut-point for FPG (5. 55 mmol/L) in predicting GDM was close to the low limit for IFG (5. 6 mmol/L) suggested by ADA in 2003. Decreasing the lower limit of IFG to 5. 6 mmol/L among women who checked before pregnancy and paying attention to those women with FPG from 5. 6 to 6. 1 mmol/L would have advantage to the evaluation and prevention of GDM.

OBJECTIVE: To investigate the efficacy of combined medical treatment on auditory neuropathy spectrum disorder and the effect of related factors on the prognosis. METHOD: Eleven cases (22 ears) diagnosed as auditory neuropathy spectrum disorder using multiple criteria including pure tone auditory threshold, impedance audiometry, acoustic reflexes, distortion products otoacoustic emission (DPOAE) and auditory brainstem response (ABR) were subjected to combined medical treatment . Eleven auditory neuropathy spectrum disorder patients diagnosed during the corresponding period but refused treatment were selected as control group. The change of pure tone auditory threshold and speech discrimination score after treatment or follow-up were evaluated for both 2 groups, and the relationship between the patients' gender, age, accompanying symptoms and curative effect were also analyzed. Data were analyzed by SPSS 19.0 statistical software using pared-sample t-test, independent-sample test and Pearson's chi-square test. RESULT: The effective rate of combined medical therapy was 59.09% (13/22) in the therapy group. PTA levels before and after-treatment were (53.92 +/- 18.86) dB HL and (47.44 +/- 14.98) dB HL respectively in 22 ears with the combined medical therapy, the improvement of which showed statistically significance (t = 5.20, P < 0.05). No obvious hearing change was noted in the 11 patients who refused therapy (P > 0.05). Speech discrimination score before and after-treatment were (29.20 +/- 25.80)% and (41.60 +/- 22.90)% respectively for the treatment group. The average improvement of speech discrimination score was (12.40 +/- 13.80)% with statistically significant difference (t = 4.02, P < 0.05). Patients accompanied with tinnitus had relatively poorer effect compared with individuals without tinnitus (t = -3.85, P < 0.05). Age is negatively correlated with the prognosis (r = -6.72, P < 0.05). Gender had no effect on the prognosis (P > 0.05). CONCLUSION The combined medical therapy with glucocorticoids helps improving the pure tone auditory threshold and speech discrimination score of auditory neuropathy spectrum disorder. In light of our findings we support the combined medical therapy as an option for patients with auditory neuropathy spectrum disorder.
