Objective To investigate the effects of different times of needle retention on cognitive function in patients with vascular cognitive impairment no dementia (VCIND). Methods One hundred and four VCIND patients were randomly allocated to group A of 35 cases, group B of 34 cases and group C of 35 cases. All the three groups received acupuncture plus medication. Of them, group A was given scalp acupuncture with 30 min retention of needles;group B, with 1 hr retention of needles;group C, with 10 hrs retention of needles. The Montreal Cognitive Assessment (MoCA) score and the ADL score were recorded in the three groups of patients before and after treatment. Results There were statistically significant pre-/post-treatment differences in the MoCA score and the ADL score in every group (P<0.05). There were statistically significant post-treatment differences in the MoCA score and the ADL score between group A or B and group C (P<0.05). Conclusions Acupuncture is an effective way to treat VCIND. It can improve cognitive function in the patients. Scalp acupuncture with 10 hrs retention of needles has a more marked effect.

Objective TO Provide information for clinical diagnosis and study the mechanism of sexual abnormality . Methods 6 cases of sexual abnormality were detected with PCR amplification and DNA sequencing techniques.ResultsSRY gene was positive in 45,XO male and 46,XY female whose DNA sequence of conserved region had no mutation.SRY gene was negative in 46,Xxmale.Three46,XY males with sexual abnormality showed SRY positive.Conclusions The sexual abnormality of 45,Xomale was caused by SRY positive.Conclusions The sexual abnormality of 45,XOmale was caused by SRY gene translocation .Sexual reverse infemale was caused by gene conseved region mutation but in male it might be caused by sexual related gene mutation on chromasome.

Objective To investigate the relationship between reading speed and center scotoma in age-related macular degeneration.Methods 46 eyes of 46 age-related macular degeneration patients underwent reading speed and center threshold examination,and the relationship was analysed.Results The mean reading speed was 183?60words/min,and had significant relationship with the deepness of the center scotoma.Conclusions The reading speed in age-related macular degeneration patient was decreased,and it related to the deepness of the center scotoma.

Objective To study the affection of acanthopanacis biochemical capsule to drug abortion in clinics.Methods 600healthy pregnant women were divided into three groups randomly;200 group A,oral intake of acanthopanacis biochemical capsule after drug abortion,200 group B oral intake of Yimuwan after drug abortion,200 group C as control.Results The discharging rate of pregnant cyst within 3days were 84.62% in grpup A,63.64% in group B and58.33% ingroup C.Theoccurrence rate of incomplete abortion within 2weeke were 1.50%in group A,6.00% in group B and 91.67% in group C .The rate of vagina bleeding within 2 weeks were 9.50% in group A,97.50% in group B and 69.80% in group C.The rate of vagina bleeding over 1 month were 1.00% in group A,6.50% in group B and 7.50%in group C.The emergency operation due to great hemorrhage were 1 in A,7 in B and 9 in C.The uterus infection were 1 in A,13 in B and 15 in C.Conclusions Acanthopanacis biochemical capsule could increase the successful fate of dug abortion within 3 days and decrease the chance of inconplete abortion .It could shorten the tine of vagina bleeding and the happening of complication.

Aim To evaluate the inhibitory effect of panaxynol(PNN) on the proliferation of rat aortic smooth muscle cell(RASMC) and its mechanisms.Methods Cell proliferation was determined using cell count and -TdR incorporation test.Fura-3/AM and confocal were used to measure intracelluar free Ca~(2+) concentration.Expression of mitochondrial transcription factor 1(mtTF1) mRNA was tested by using RT-PR.Results PNN inhibited the RASMC proliferation and DNA synthesis induced by serum and PDGF-BB in a dose-dependent manner.9 ?mol?L~(-1) of PNN inhibited the increase of intracelluar free Ca~(2+) concentration induced by PDGF-BB.PDGF-BB upregulated the expression of mtTF1 mRNA,which could be suppressed by 3,9 ?mol?L~(-1) of PNN significantly.Conclusions PNN can inhibit RASMC proliferation significantly,which might be related to the decrease of intracellular free Ca~(2+) concentration and mtTF1 mRNA expression.

Objective:To construct an expression plasmid of siRNA against gene hIAP-2 and to assess its effect on breast cancer cell line MCF-7.Methods: A hIAP-2 siRNA plasmid was constructed with mU6pro vector containing U6 promotor and its RNAi effect on MCF-7 cells was detected by RT-PCR and Western blot.The effects of the plasmid on MCF-7 proliferation were analyzed by MTT assay,on the cell cycle by flow cytometry,and on the cell morphology by Hoechst staining.The activity of caspase-3 was determined with its substrate Ac-DEVD-pNA and the expression of some related proteins was detected by Western blot.Results: The hIAP-2 siRNA plasmid knocked down hIAP-2 expression in MCF-7 cells specifically and obviously,inhibited tumor cell proliferation and arrested the MCF-7 cells at G_(1) phase.After hIAP-2 gene was silenced,MCF-7 cells became multinuclear and had macronucleus;procaspase-3 was activated and its expression was increased.The protein levels of I?B?(p37) and p21~(waf1) increased,of NF-?B(p65) decreased and Cyt C remained unchanged.Conclusion: hIAP-2 in MCF-7 cells plays a crucial role in cell proliferation and cell cycle progression.Mitotic cell death might be the main way of the cell death;G_(1) arrest after DNA damage might be associated with the p21~(waf1) increase.

Objective:To study the mental health status of middle school students in Three-Gorges area of Chongqing in order to provide theory support for mental health education. Methods:1 014 middle school students in Three-Gorges area were tested by SCL-90. Results:The occurrent rate of mental problems with students was 19.8%,of which the first three factors were hostility,compulsiveness and interpersonal sensitivity. Girls’ overall score and mean scores of interpersonal sensitivity, depression,anxiety and phobic anxiety were significantly higher than boys’. The overall score and factor mean scores of senior high school students were significantly higher than those of junior high school students’ except hostility and phobic anxiety factors. The mean scores of interpersonal sensitivity,hostility and phobic anxiety factors were significantly higher than the counterparts in the norms of middle school students,while the mean scores of somatization and anxiety factors were significantly lower than the counterpart in the norms of middle school students. Conclusion:The mental health status of middle school students in Three-Gorges area of Chongqing is poor,and mental health education should be enhanced by all of us.

It is the trend worthing a close attention in the 21st century to consider the quality of life while focusing on control of epileptic seizures simultaneously during the treatment of epilepsy and related services. The impact of the epilepsy on many aspects of quality of life are caused by many factors, including the type of epilepsy, site of the epileptic loci, onset age, frequency of attack, duration and course of disease, and especially side effects of anti-epileptic drugs. In the treatment of epilepsy, choice of drugs should be made based on benefits and adverse effects, it is necessary to achieve better therapeutic effects, but also to reduce the impact of drugs on the level of intelligence in children and to promote the single-drug treatment. The purpose of the treatment of epilepsy is no longer aimed at seizure free as the end point, consideration must be given to beth the control of seizure and the improvement of the quality of life.

Objective:The pathological characteristics of tissue obtained from the placental bed biopsies (method A), placental basal plate sections (method B) and placental bed vacuum suction(method C) were evaluated to find a best sampling method to study the uterine spiral arteries. Methods:Histology obtained from 33 patients using method A and B and obtained from 51 patients using method C was analysised ,retrospectively. The differences of tissue and the spiral artery pick-up rate were compared. Results:Both the decidua and myometrium could be obtained by method A and C. It is impossible to get myometrium by method B. The spiral artery pick-up rate of method C is significantly higher than that of method A(? 2 =7.31, P
