Objective:To study the effect of articulation disorder on psychology action of cleft palate patients after operation.Methods:65 patients were asked to answer the psychology questionnaire.Results:The patients of misarticulation all have some degree of psychological disability,and unusual psychology action would affect pronunciation treatment.Conclusion:Patients with misarticulation have psychology problems in some degree,which would affect the clinic treatment of cleft palate.

In recent years, it was found that heart was significantly protected against ischemia-reperfusion injury if it was first preconditioned by brief ischemia or by administering a potassium channel opener. Both of these preconditioning strategies were found to require opening of a K(ATP) channel, we showed that this pivotal role was mediated by the mitochondrial ATP-sensitive K+ channel (mitoK(ATP)). As the mechanism was not clarified yet, this paper reviewed the evidence showing that the mechanism and the characters of mito K(ATP) and its cardioprotection against ischemia-reperfusion injury

Objective To evaluate the effects of hydrogen peroxide (H 2O 2) on cardiomyocytes and the protective effect of pinacidil preconditioning on injured primary cultured cardiomyocytes. Methods We isolated and cultured cardiomyocytes in neonatal mice by trypsin digestion technique. The cells were inoculated in 96-well culture plate at the density of 1?10 5/ml. Cells were divided into control group and 400, 600, and 800 ?mol/L H 2O 2 treatment groups. MTT assay was used to determine the cell vitality at 1, 3, 6, 12, and 24 h after H 2O 2 treatment. The effects of pinacidil preconditioning were also observed. Results The effect of H 2O 2 on the damages to cardiomyocytes was in dose- and time-dependent manners. Pretreatment with pinacidil at the concentrations of 1?10 -4 , 1?10 -5 , and 1?10 -6 mol/L, particularly 1?10 -6 mol/L, could increase the activity of cardiomyocytes treated with H 2O 2. Conclusion Pinacidil preconditioning at lower doses can protected cardiomyocytes from injuries induced by H 2O 2.

Objective To investigate the expression and significance of Peripheral blood of Toll-like receptor-4 and cytotoxic T lymphocyte-associated antigen-4 in patients with essential hypertension. Methods We selected 35 patients with hypertension and 20 healthy people.We used flow cytometry to investigate TLR4 expression levels, and ELISA to detect the expression of CTLA-4. Results TLR4 expression in peripheral blood of patients with hypertension was (8.63 ±1.16)%, significantly higher (5.27 ± 1.25)%.The difference was statistically significant (t = 6.16,P < 0.05); CTLA-4 expression in peripheral blood of patients with hypertension was significantly higher (P<0.05); Hypertensive patients with CTLA-4 positive rate and TC, LDL-C was positively correlated (P<0.05); TLR4 and CTLA-4 was positive correlation (r = 0.886,P < 0.05). Conclusions TLR4 and CTLA-4 were high expression in hypertensive patients with hypertension,and related to hypertension.

The integrator complex is multifunctional and contains at least 12 evolutionarily conserved subunits in hu-mans.It interacts with the C-terminal tail of the largest subunit of RNA-polymeraseⅡ ( RNAPⅡ) to promote 3′-end pro-cessing of small nuclear RNA (snRNA) U1/U2.It also interacts with RNAPⅡ, NELF and Spt5 to regulate NELF-mediated RNAPⅡpause/release and processivity at coding genes .Recently, the integrator complex is also reported to be involved in DNA damage response , dynein recruitment to the nuclear envelope , integrity of Cajal bodies , adipose differentiation , hem-atopoiesis , ciliogenesis , tumorigenesis and generation of viral microRNAs .This review discusses related research progress in the integrator complex .

BACKGROUND:Traditional total knee arthroplasty adopts medial parapatel ar approach, which induces severe trauma, requires long-term rehabilitation, and interferes the end point of quadriceps femoral tendon on superior patel ar pole. Total knee arthroplasty by subvastus approach has no impact on the knee-extension equipment, but it cannot provide sufficient exposure of surgical field and can induce damage to femoral muscle, so its application and safety need further exploration.
OBJECTIVE:To explore clinical effect of total knee arthroplasty by subvastus approach and medial parapatel ar approach.
METHODS:A total of 78 patients with 82 knees who were candidates for total knee arthroplasty were randomly divided into two groups. Treatment group (39 cases;41 knees) was given subvastus approach and control group (39 cases;41 knees) was given median parapatel ar approach. The knee function, range-of-motion of knee joint and complications after total knee arthroplasty were observed and compared.
RESULTS AND CONCLUSION:Compared with control group, the operation time in treatment group was significantly increased, while the postoperative wound drainage, straight leg raising time and walking time were obviously reduced (P<0.05). The scores of HSS before surgery and 12 weeks after surgery were not significantly different between the two groups (P>0.05), while at 1 and 6 weeks after surgery the scores in treatment group were significantly higher than those in control group (P<0.05). The range-of-motion of knee joint and MMT rank for quadriceps muscle were significantly improved in two groups after treatment (P<0.05), and those indicators in treatment group were more significant than the control group (P<0.05). The incidences of complications in treatment group and control group were 2.6%and 15.4%, respectively, with statistical y significant difference (P<0.05). The total knee arthroplasty by subvastus approach has less impact on the extensor mechanism, improves the recovery of knee function and range-of-motion of knee joint, and reduces the incidence of complications.
