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 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.

ObjectiveTo investigate the correlation of TIMI risk score and plasma brain natriuretic peptide (BNP) in patients with Acute myocardial infarction. MethodsTIMI risk score were calculated in 63 patients with acute myocardial infarction;At the same time plasma brain natriuretic peptide were measured by enzyme-linked immune absorption assay(ELISA). Analyze the correlation of TIMI risk score and plasma brain natriuretic peptide. ResultsNine patients of 63 occurred cardiavascular events during hospitalization or follow-up( 14.3％ ). The incidence of MACE increased significantly with the rise of TIMI risk score and BNP level. The TIMI risk score was positively correlated with the plasma BNP level( r =0.73 ,P ＜ 0. 05 ). ConclusionThe higher TIMI risk score and BNP level, the worse the prognosis, it could be use to predict the prognosis.

Objective To explore the clinical efficacy of cetuximab combined FOLFOX chemotherapy on colon and colorectal cancer.Methods Forty patients with colon and colorectal cancer were randomly divided into observation group and control group,and 20 cases for each group.Patients in control group were treated with oxaliplatin + leucovorin + 5-fluorouracil,and in the observation group were given cetuximab (the first does was 400 mg/m2 at the first week,then the second week and follow weeks was 250 mg/m2 1 time/week for 6 week) plus the treatment as control group.The clinical efficacy,adverse effect and 1-year survival in the two groups were recorded.Results The total effective rate and clinical benefit rate in observation group were 60％ (12/20)and 85％ (17/20) respectively,which significantly higher than the control group (30％ (6/20) and 65 ％ (13/ 20),x2 =18.18,10.67,P ＜ 0.05).Skin rash rate in observation group was 55％ (11/20),which was significantly higher than that of control group (15％ (3/20),x2 =35.16,P ＜0.05).Half-year survival rate and 1-year survival rate of patients in observation group were 75％ (15/20) and 45％ (9/20) respectively,significantly higher than the control group (50％ (10/20) and 25％ (5/20),x2 =13.33,8.791,P ＜ 0.05)~ Conclusion Treatment scheme of Cetuximab combined FOLFOX chemotherapy is proved to be an effect of treating advanced colon and colorectal and be with the low adverse effect.

Systems biology is a new science of the 21st century, which resembles traditional Chinese medicine (TCM) in many aspects such as study method and design. Adoption of systems biology approach would do much help for exploring the scientific connotation of TCM syndrome and the modernization of Chinese herbal medicine. Its technological platforms, such as genomics, proteomics and metabonomics, provide powerful tools for the study of the essence of TCM syndrome and the function of herbal compound recipe. Compared with other molecular biological methods, such as genomics and proteomics, metabonomics method is more direct and more concise, especially for providing an effective method for the study of TCM therapy in preventing and treating kidney diseases.

Objective To analyze the clinical feature of X-linked chronic granulomatous disease (X-CGD) and gene mutation of CYBB. Method The clinical data of X-CGD in one child and the results of CYBB gene detection in his family were reviewed. Results This boy had onset in the neonatal period and presented with recurrent severe pulmonary infection as his main manifestation. Results of nitroblue tetrazolium test (NBT) in both non-stimulation group and LPS stimulation group in the child were 0, and neutrophil oxidation index (NOI) was 1.15. Gene analysis showed a deletion mutation in exon 6 of CYBB gene in the child (579-582delATTA), which resulted in frameshift mutation started from coding sequence of 189—isoleucine (I) and stop codon occured in advance in the 212th amino acid (I189fsX212). Both the child's mother and grandmother were carriers of the mutated gene. The same deletion mutation was not found in the CYBB gene in the amniocyte from the mother's next child. Conclusion One case of X-CGD patient with CYBB gene mutation and his families were diagnosed by gene detection. Prenatal diagnosis can avoid the birth of children with X-CGD.

The rational prescription evaluation is important for improving the medical quality and ensuring prescription safety.For the last few years, the health authorities have issued a series of files in order to regulate clini-cal medical conducts, and reduce the irrational prescription.Hospitals are also paying more attention to the rational medicine evaluation.The evaluation is likely to be doubted and resisted for the difference of evaluation personnel, e-valuation personnel quality and evaluation criterion.Therefore, the smooth development of hospital rational prescrip-tion evaluation need to adopt effective management measures, which is connected with responsibilities, guaranteed by rewards and punishments and based on actualities, and establish various evaluation management mechanism to ensure continuous correction and updating at work.

Objective To evaluate the effects and security of single or combined sufentanil application on sedation and analgesia for mechanically ventilated patients in intensive care unit(ICU).Method A total of 160 ICU patients with mechanical ventilation were randomly allocated into four groups:sufentanil group,sufentanil plus midazolam group,sufentanil plus dexmedetomidine group and fentanyl group.Facial pain scale(FPS),Ramsay score and vital signs were employed to assess the effects of different therapies on organ functions and adverse reactions.Result After the treatment,FPS in all groups were significantly decreased and maintained around 3 points.Ramsay scores were significantly increased(P <0.001)and the score in group given sufentanil combined with midazolam or dexmedetomidine at the time points of30 min,1 h,6 h were even higher.Compared with the preoperative data,indicators of lung function(PaCO2and blood lactic acid),liver function(AST)and renal function(Cr)were decreased in all groups(P <0.05).Respiratory rate in the fentanyl group was significantly higher than the others.Total consumption ofsufentanil in group with combined sufentanil application was significantly lower.No significant differencesin adverse reactions were noticed among the groups(P >0.05).Conclusion For mechanically ventilatedpatients,sufentanil has efficient sedative and analgesic effects with less physiological interference and severe adverse reactions.Combined application is beneficial in decreasing total sufentanil consumption andinhibition to respiratory system,which is worthy of being spread.
