Objective To provide clinical evidence for the optimal acupuncture time in acupuncture treatment of hearing disorder in kids with cerebral palsy.Method Ninety eligible patients were randomized into 3 groups, 30 in each group. Group A was treated for 30 min, group B for 45 min, and group C for 1 h. The hearing improvement was evaluated by using brain-stem auditory evoked potential (BAEP).Result The detection of BAEP showed that the latent and peak periods of wave I,Ⅲ, and V were significantly shortened in the 3 groups after intervention (P<0.01), suggesting that acupuncture can produce a marked efficacy in treating hearing disorder in cerebral palsy. The inter-group comparisons showed that the efficacy of group A was significantly higher than that of group B and C (P<0.05); there was no significant difference in comparing the efficacy between group B and C (P>0.05). It’s indicated that the optimal acupuncture time span should be 30 min.Conclusion With the same acupuncture skills, acupuncture for 30 min can produce a comparatively higher efficacy in treating infantile hearing disorder.

Objective To explore the risk factors of prehypertension and the relationship between blood pressure and atherosclerosis.Methods The data of 456 cases in the Department of General Medicine were cross-sectional analyzed,including 174 subjects with normotension and 282 with prehypertension.The information was consisted of demographic characteristics,blood pressure,blood biochemical metabolism index,brachia-ankle pulse wave velocity (baPWV),ankle-brachial index (ABI) and carotid intima media thickness (CIMT).Results Compared to normotension group,the levels of systolic pressure,diastolic pressure,pulse pressure,body mass index,fasting blood glucose,glycosylated hemoglobin,triglyceride,uric acid,and C-reactive protein in prehypertension group were significantly increased (P ＜ 0.05) ; and high-density lipoprotein cholesterol was significantly decreased (P ＜0.05) ; the body mass index(OR =1.185),triglyceride(OR =1.302),and fasting blood sugar (OR =1.690) were the independent risk factors of prehypertension ; baPWV and CIMT in prehypertension group were higher,but ABI and artery atheromatous plaque rate were not obvious changed.When baPWV or CIMT were set as the dependent variables,multiple linear regression analysis showed that systolic blood pressure(β =0.226,P =0.007),fasting blood glucose(β =0.209,P =0.018),and age(β =0.279,P =0.002) were risk factors of baPWV;systolic blood pressure(β =0.118,P =0.015),body mass index(β =0.109,P =0.001),and age(β =0.396,P =0.001) were risk factors of CIMT.Conclusions Body mass index,triglycerides,and fasting blood sugar were the independent risk factors of prehypertension.The early subclinical damage of hardening of the arteries was occurred in the prehypertension cases,and systolic blood pressure was closely related with baPWV or CIMT.

Objective To study the distribution of variable number tande repeat(VNTR) polymorphisms of the platelet membrane glycoprotein Ⅰ b? in Han nationality at Harbin and the relationship between these polymorpbisms and cerebral infarction(CI).Methods The identification of alleles and genotypes of VNTR polymorphism of the glycoprotein Ⅰ b? gene was performed by polymerase chain reaction (PCR)in 200 healthy individuls and 200 CI patients(77 lacunar infarction patients and 123 atherosclerotic thrombotic infarction patients),to analyze The relationship between gene polymorphisms and cerebral infarction.Results(1)There were three types of alleles:B、C、D,and five types genotypes:BC,BD,CC, CD,DD in Harbin Han nationality.No person with A allele and BB genotype was found.(2)No statistically significant differences of GP Ⅰ b? gene VNTR polymorphism was found between CI patients or subtype CI patients and controls(P=0.412 and 0.572,respectively).Conclusions(1)This study indicates that the C and D alleles of VNTR polymorphisms of GP Ⅰ b? are the main alleles while the CC and CD genotypes are the main genotypes in Harbin Han people.(2)Our findings indicate that no association exists between the VNTR polymorphism of platelet GP Ⅰ b? gene and CI.

It was the first time that the complotypes of 84 chromosomes from Han nationality healthyChinese families investigated and analyzed in Guangdong are a with the methods adopted fromthe international complement reference laboratory.The results showed 18 various complolypeswere identified.The precedent complotypes are SC31,SC42,SC32 and SC41.There were 7 com-potypes of them existing the linkage disequilibria.The highest allotypes gene frequencies of thefour loci of complotypes were respectively as follows,BF S for BF alleles,C2C for C2 alleles,C4A3 and C4A4 for C4A alleles,C4B2 and C4B1 for C4B alleles.The C4AQO allele for C4A lo-cus was 4.8% and 1.2%C4BQO alleles for C4B locus.The frequencies of major complolypesfrom the data showed the similarities among Mongolian,Caucasian,Japanese and south easternAsia populations.The significance of the different frepuencies between the complotypes has beendiscussed.

Objective To investigate the expression of integrin β3 and osteopontin(OPN) in eutopic and ectopic endometrium of adenomyosis. Methods From January 2007 to July 2008, the endometrium specimens were collected from 43 patients with adenomyosis undergoing hysterectomy in Peking University First Hospital. Eutopic endometrium were 11 in proliferative phase and 32 in secretory phase (18 cases in mid-secretory phase) were collected. Ectopic endometriums were also collected. In the mean time, it was chosen 41 cases with pure subserous uterine myoma or cervical intraepithelial neoplasia (CIN) Ⅱ-Ⅲ treated by hysterectomy as controls including 12 endometrium in proliferative phase and 29 endometrium in secretory phase (19 cases in mid-secretory phase). The expression of Integrin β3 subunit and OPN in the endometrium were assessed by immunohistochemical staining and quantitative real-time polymerase chain reaction. Results (1)Immunohistochemical staining showed that positive staining of integrin β3 and OPN were present predominantly in eutopic and ectopic endometrial glandular epithelium. There was significant different protein expression of integrin β3 and OPN, which were 1.6±0.8 and 1.7±0.7 in eutopic endometrium,1.7±0.7 and 1.8±0.9 in ectopic endometrium,2.1±0.9 and 2.0±0.9 in control endometrium (P<0.05). The protein expression of integrin β3 and OPN in eutopic endometrium of adenomyosis in the proliferative phase(0.8±0.4 and 0.7±0.3) were remarkably lower than those of the secretory phase(1.8±0.8 and 1.9±0.8,P<0.01). The protein expression of integrin β3 and OPN in the endometrium of controls in the proliferative phase(1.0±0.4 and 1.0±0.4) were significantly lower than those of the secretory phase(2.5±0.7 and 2.5±0.7)(P=0.000). In the mid-secretory phase, the protein expression of integrin β3(2.0±0.9) and OPN (2.1±0.8)in eutopic endometrium of adenomyosis were significantly lower than that of control endometrium(2.7±0.5 and 2.7±0.7)(P<0.01). (2)The mRNA expression level of integrin β and OPN in eutopic and ectopic endometrium were assessed by quantitative real-time PCR(result was shown by median index). It was observed that integrin β3 mRNA and OPN mRNA were significantly lower in the eutopic endometrium of adenomyosis (4.69 and 4.23), when compared with ectopic endometrium(7.96 and 14.84)and controls (13.47 and 17.40) (P<0.05). Eutopic endometrium had higher mRNA expression of integrin β and OPN mRNA in the secretory phase (5.54 and 11.40) than that in the proliferative phase(2.69 and 3.30) (P<0.01).The mRNA expression level of integrin β and OPN of control endometrium in the proliferative phase (3.12 and 4.75)were significantly lower than that in the secretory phase(19.94 and 21.00, P=0.000). The mRNA expression of integrin β and OPN were 10.10 and 14.34 in the mid-secretory phase, which were significantly lower than 21.50 and 24.18 in control endometrium(P<0.05). Conclusions High expression of integrin β3 and OPN in ectopic endometrium of adenomyosis may cause endometriotic lesions; abnormal expression of integrin β3 and OPN in the endometrium of adenomyosis during the implantation window may contribute to infertility in some patients.
