The potential advantage of Traditional Chinese Medicine(TCM) theories of disease prevention,especial the thinking mode of "health preservation from both physique and spirit "has been generally recognized and widely understood by international society increasingly.In TCM,methods of disease prevention are various and the "health preservation from both physique and spirit" is praised the highest.This article demonstrates the theory that preserving the spirit firstly and then combining with physique,also the methods of keeping an undisturbed spirit and protecting the physique from any harm,for the purpose to make new contribution to the mankind’s health-care industry.

Objective To explore the hemodynamic changes in the brains of newborns with intracranial hemorrhage.Methods Totally,61 newborns,born in Anyang Maternal and Child Health Hospital of Henan Province,with intracranial hemorrhage diagnosed by ultrasound in early neonatal period,and 50 healthy newborns,also born in the same hospital from December 1,2010 to June30,2012,were selected.Intracranial hemorrhage newborns were graded according to the severity of hemorrhage and divided into mild (n=45) and severe groups (n =7).The peak systolic flow velocity (Vs),end diastolic velocity (Vd),mean flow velocity (Vm) and resistance index (RI) in the middle cerebral artery (MCA) and anterior cerebral artery (ACA) of brain were measured by Doppler ultrasound.Ttest was applied for statistical analysis.Results Among the 61 neonates with intracranialhemorrhage,12(19.7％) were grade Ⅰ,42(68.9％) were grade Ⅱ,6(9.8％) were grade Ⅲ,and one (1.6％) was grade Ⅳ.The Vs,Vm and Vd of MCA and ACA in the mild and severe intracranial hemorrhage group were significantly lower than those in the control group,the differences were statistically significant [MCA:(55.1±9.1) cm/s,(53.0±6.5) cm/s vs (60.1± 10.3) cm/s;(34.2±6.1) cm/s,(32.5±5.2) cm/s vs (38.2±6.9) cm/s; (17.1±4.8) cm/s,(15.3± 4.0) cm/svs (20.2±5.3) cm/s.ACA:(41.3±11.7) cm/s,(39.4±9.2) cm/s vs (45.3±9.8) cm/s;(25.2±5.8) cm/s,(23.3±4.9) cm/s vs (28.1±5.9) cm/s;(15.0±3.9) cm/s,(13.2±3.1) cm/s vs (15.9±3.8) cm/s,all P＜0.05].But the RI values were significantly higher in the control group,the differences were statistically significant (MCA:0.70 ± 0.10,0.77 ± 0.07 vs 0.62 ± 0.10 ; ACA:0.67±0.06,0.73±0.08 vs 0.61±0.05;all P＜0.05).TheVs,Vm and Vd of MCA and ACA in the severe intracranial hemorrhage group were significantly lower than in the mild hemorrhage group,while the RI values were significantly higher,and the differences were statistically significant (all P＜0.05).Conclusions Newborns with intracranial hemorrhage have significant hemodynamic changes in the brain and more prominent changes could be found in those with severe intracranial hemorrhage.

Objective To explore the effective disinfection and management measures of standby aspirators. Methods Randomly sampled 17 standby aspirators in our hospital and examined whether their liquid storage bottles and covers were contaminated by pathogens.According to the situation,we developed appropriate measures to intervene.4 months after intervention,we sampled 17 standby aspirators which were tested again. Results 82.4% liquid storage bottles and 88.2% covers were contaminated. While the contamination rate after intervention was zero.The pathogens found were mainly Pseudomonas Aeruginosa, Klebsiella pneumoniae and other opportunistic pathogens.Conclusions To strengthen the disinfection management of standby aspirators can control the contamination of standby aspirators.

To investigate the effect of casein phosphopeptide-amorphic calcium phosphate(CPP-ACP) on the growth of Lactobacillus fermentum and to evaluate the possibility of CPP-ACP as a biological anticariogenic agent. Lactobacillus fermentum was inoculated in BHI with different concentrations of CPP-ACP and grew in anaerobic condition at 37 ℃ for 48 h. Used MTT method to evaluate the effects of CPP-ACP on the growth of Lactobacillus fermentum. CPP-ACP inhibited the growth of Lactobacillus fermentum effectively. With the concentration of CPP-ACP increasing, the values of A(550 nm) decreased. It was found that CPP-ACP had inhibitory effect on the growth of Lactobacillus fermentum, the inhibitory effect increased with CPP-ACP concentration.

ObjectiveTo assess the clinical value of minimally invasive transforaminal lumbar interbody fusion(TLIF) through the Wiltse approach for the treatment of lumbar spondylolisthesis. Methods Sixty-nine patients with lumbar spondylolisthesis were randomly divided into two groups. Group A underwent minimally invasive TLIF via the Wiltse approach, Group B via the traditional approach. There were 31 cases in group A, the affected level was L4.5 in 19 cases and L5S1 in 12. The degree of vertebrae slippage was Ⅰ degree in 17 cases,and Ⅱ degree in 14. There were 38 cases in group B, the affected level was L4,5 in 22 cases and L5S1 in 16. The degree of vertebrae slippage was Ⅰ in 21 cases, and Ⅱ in 17. The Japanese Orthopaedics Association (JOA) score, visual analogue scale (VAS) of low back pain and leg pain were evaluated at 3, 6, and 12 months follow-up. The post-operative dynamic X-rays, CT and/or MRI were used for image evaluation. ResultsThere was no statistically difference in operating time between the two groups. The incision length, blood loss and exposing time of group A were shorter than those of group B. The JOA scores, recovery rate, VAS of low back pain and leg pain, interbody fusion rate and atrophy rate of multifidus in group A were 24.7±3.5, 77.0％±3.1％, 1.0±0.7, 1.1±0.3, 71.0％±5.8％, 2.1±0.2, respectively, and in group B were 24.3±2.8, 73.6％±6.4％, 3.1±0.6, 1.8±0.5, 76.3％±6.1％, 0.5±0.1, respectively. The VAS of low back pain was lower in group A than in group B. The atrophy rate was better in group A than in group B. Conclusion Both TLIF approaches can acquire satisfactory clinical results. Minimally invasive TLIF through the Wiltse approach can significantly reduced damage of multifidus and incidence of chronic low back pain postoperative.

BACKGROUND: It is of great significance to understand the effects of different components of blood pressure on the occurrence of cerebrovascular diseases and administer proper decompression treatments in various situations.OBJECTIVE: To study the relationship of increased pulse pressure with the occurrence and severity degree of cerebral infarction by analyzing the data of pulse pressure recorded in hospitalized patients with acute cerebral infarction.DESIGN: Case-control analysis.SETTING: First Affiliated Hospital of Harbin Medical University.PARTICIPANTS: A total of 300 patients hospitalized at the First Affiliated Hospital of Harbin Medical University between June 2002 and January 2003 for ischemic cerebral infarction were enrolled, including 196males and 104 females aged (57.9±11.9) years. Another 199 persons who came to the same hospital for physical examination at the same period were set as normal group, including 110 males and 89 females aged (55.9±12.4)years.METHODS: ① Measurement of blood pressure: Systolic pressure and diastolic pressure of each person were recorded with mercury sphygmomanometer at the site of brachial artery of the right upper extremity and pulse pressure was calculated. ② Evaluation of neurological impairment:Upon hospital admission, each patient with ischemic cerebral infarction was evaluated with the stroke scale made by the National Institute of Health (NIHSS), in which a higher score means more severe infarction.MAIN OUTCOME MEASURES: ① Comparison of blood pressure parameters of subjects in the two groups. ② Distribution of different pulse pressure levels in the two groups. ③ Comparison of pulse pressure of subjects of different age in the two groups. ④ Results of non-parameters tests of neural function loss in cerebral infarction patients with different pulse pressure levels.RESULTS: ① Mean systolic pressure: It was significantly higher in the case group than in control group [(152±22), (133±19) mm Hg, t' =10.494,P ＜ 0.01]. Mean diastolic pressure: It was higher in the case group than in control group [(93±14), (81±11) mm Hg, t' = 10.129, P ＜ 0.01]. Meanpulse pressure: It was higher in the case group than in control group [(59.61±11.86), (51.93±14.10) mm Hg, t' =5.612, P ＜ 0.05]. Pairwise corre lation analysis showed that Pearson correlation coefficient between pulse pressure and systolic pressure was 0.789 (P ＜ 0.01); Pearson correlation.coefficient between pulse pressure and diastolic pressure was 0.169 (P ＜ 0.01). Therefore, there was a close correlation between pulse pressure and systolic pressure. ② Pulse pressure was distributed between 60 mm Hg and 69 mm Hg in most subjects in the case group, which accounted for 27.7%.It was 40-49 mm Hg in control group, which accounted for 35.7%. It indicated that the incidence rate was high when the pulse pressure was over 60 mm Hg in cerebral infarction. ③ Pulse pressure increased with age.The level of pulse pressure in 40-69 years case group was higher than that in 40-69 control group [(54±16), (45±9)mm Hg, t=4.86, P=0.000]. ④ Patients with cerebral infarction of different levels of pulse pressure were given non-parameter tests of neurological impairment evaluation. The resuits of Kruskal-Wallis test were χ2=4.779, P=0.572 ＞ 0.05; results of median test were as x2=8.365, P=0.213 ＞ 0.05. The results of the two non-parameter tests suggested that there was no significant differences in hospitalization evaluation, that is, although the pulse pressure increased obviously in cerebral infarction, the degree of increase had no correlation with the severity of neurological impairment.CONCLUSION: The increase of pulse pressure is related to the occurrence of cerebral infarction and is also an important factor for evaluating cerebral infarction. However, pulse pressure change is not related to the severity of cerebral infarction.

BACKGROUND: Medical order-obeying behavior(MOOB) in patients with essential hypertension(EH) cau directly affect the progression and prognosis of the disease. What factors, in turn, affect MOOB?OBJECTIVE:To analyze factors affecting MOOB in EH patients.DESIGN: Cross-sectional study.SETTING: Foreign Guests Ward of Qindu Stomatological Hospital, Fourth Military Medical University of Chinese PLA.PARTICIPANTS: A total of 205 patients with EH were admitted into the Foreign Guests Ward of Qindu Stomatological Hospital, Fourth Military Medical University of Chinese PLA from January 1998 to August 2000. Inclusion criteria: In accordance with WHO diagnostic criteria for hypertension. Exclusion criteria: Diabetes and other cardiovascular diseases. Altogether 164 patients with the mean age of (51 ± 5) years, 122 men and 42 women , accorded to the inclusion criteria.METHODS: The 164 patients were investigated with the self-designed questionnaire concerning MOOB in EH patients; patients' sex, educational level, family economic conditions, disease duration and other factors affecting MOOB were observed.MAIN OUTCOME MEASURES:Factors related to the patients' MOOB.RESULTS:53.0% (87/164) patients followed the medical orders and persisted in exercise therapy, 58.5 % ( 96 / 164 ) patients followed reasonable diet, 51.6% (32/164)patients quitted smoking and alcohol drinking, 82. 3% (135/164) received regular recheck-up, 64.6% (106/164) followed the medicinal treatment prescribed. Sex did not influence MOOB significantly. The rate of medical-order disobedience was higher in illiterate people and those with education below junior middle school level, but lower in those with education above senior middle school level(x2 =7.25, P < 0.01) . The disobedience rate was lower in patients with the mean income of > 500 yuan/month than in those with < 500 yuan/month(x2 = 39.4, P < 0.01),and was also lower in patients with disease duration < 1 year than those with disease duration > 1 year (x2 =5.66, P < 0.05).CONCLUSION; Medical order-obeying behavior in EH patients is poor, and it is significantly influenced by patients' educational level, family economic conditions and disease duration.

Objective To explore the relationship between the expression of Dishevelled2 and Vangl2 proteins and the development of mouse palate. Methods Twenty-four pregnant mice were randomly divided into eight groups, and the mouse embryos were obtained at eight clock of the pregnant day of thirteen(p13d8h), p13d14h,p13d22h,p14d8h,p14d14h,p14d22h,p15d8h and p15d22h respectively, then paraffin sections were made conventionally.The distrubution and dynamic changes of Dishevelled2 and Vangl2 proteins in the embryonic palatal shelves were detected by immunohistochemistry and image analysis. Results It was found that the two kinds of proteins expressed in the epithelium and mesenchyma of the mouse palatal shelves at different development stages. The expression levels of the Dishevelled2,in both of the epithelium and mesenchyme of the palatal shelves, increased first (p13d8h-p13d22h),then decreased rapidly(p13d22h-p14d14h), and then increased again(p14d14h-p15d22h). The expression of Vangl2 protein in the mesenchyma showed a similar trend to that of the Dishevelled2, but there was no obvious regularity in the epithelium. In addition, the expressive levels of both kinds of proteins in the epithelium were significantly higher than those in mesenchyma of the palatal shelves. Conclusion Dishevelled2 and Vangl2 proteins might directly or indirectly take part in the regulation process of mouse palate morphogenesis.
