OBJECTIVE:To evaluate the effect of temozolomide(TMZ)in combination with dexamethasone(DXM)on the proliferation of human gliocytoma U251 cells in vitro.METHODS:Human U251 cells were assigned to 1 of the 3 groups: TMZ(10,25,50,100,200,400?mol?L~(-1),respectively)alone or in combination with 40?mol?L~(-1)DXM(TMZ+DXM group)or control group(none drug).After treatment for 72 hours,the cell morphology,cell inhibition ratio,cell cycle and the apoptotic rate were detected.RESULTS:When TMZ concentration was greater than 100?mol?L~(-1)the cell inhibition ratio was higher in TMZ-treated group than in TMZ+DXM-treated group(P

BackgroundWith the number of diabetics increases,people pay more attention to the diabetic keratopathy.The major mechanism leading to diabetic keratopathy is diabetic corneal neuropathy.So it is significant to observe pathologic mechanism of diabetic corneal neuropathy. Objective To investigate the protective effects of edaravone( a free radical scavenger) on corneal nerve of rats with experimental diabetic corneal neuropathy,then explain the effects of oxidative stress in the pathologic mechanism of diabetic corneal neuropathy. Methods Seventy Sprague-Daxley male rats were taken as experimental subjects and 20 of them were used as normal control group.The remaining 50 were induced to be diabetic mellitus by a single intraperitoneal injection of streptozotocin and divided into 2 groups randomly:edaravone treated group and diabetic control group.In the edaravone treated group,edaravone(0.2 g/L) eye drops were used 3 times a day until the animal was killed.Five rats in each group were sacrificed at 6,8,10 and 12 weeks respectively.Then the corneal sensation,number of corneal nerve fibers,morphology,content of malondialdehyde(MDA) and activity of superoxide dismutase(SOD) in the corneal tissue were detected.ResultsIn the diabetic control group,the corneal sensation and the number of corneal nerve fibers were decreased,the density of neural network for cluster was sparse,the nerve activity was decreased,the content of MDA in the corneal tissue was significantly increased,the activity of SOD in the corneal tissue was significantly decreased (P＜0.01 ).Accompany with the course of disease,the above change was obvious day after day.Compared with the diabetic control group,the corneal sensation and the morphological abnormalities in corneal nerve of edaravone group were improved significantly which had the partial branches to the 12th week,the content of MDA in the corneal tissue was significantly decreased,the activity of SOD in the corneal tissue was significantly increased (P＜0.01).Conclusions Edaravone can lower diabetic corneal nerve of rats with experimental diabetic corneal neuropathyinjury,Oxidative stress may be a critical pathologic mechanism of diabetic corneal neuropathy.

There are one third of synthesized proteins must be secreted to the cell surface or to the surrounding environment to acquire their native functional state. Most of them are exported by Sec translocase (secretion pathway). Sec translocase consists of a membrane embedded protein-conducting channel, termed SecYEG and a peripherally associated motor domain, the ATPase SecA. The SecDFyajC heterotrimeric membrane protein complex can facilitates protein translocation. SecB is a molecular chaperone that functions in the protein translocation pathway. SecM (secretion monitor) encoded by the 5' region of the secM-secA mRNA, which elongation arrest is required for upregulated expression of SecA. The signal sequence in the N terminus of the nascent peptide is first recognized by the signal recognition particle (SRP). SecB, the Sec-system-specific chaperone, channels the preprotein to the Sec translocation pathway and, ad- ditionally, actively targets the bound precursor to the translocase by its ability to bind SecA. The preprotein-bearing SecA then binds to the membrane, at a high-affinity SecA-binding site, SecYEG, which constitutes a channel for polypeptide movement. Continued translocation requires cycles of ATP hydrolysis bySecA, which is thought to occur in a step-wise fashion with a step of 20~30 amino acid residues.

With Jianyu (LI 15), Jianliao (TE 14) and Jianzhen (SI 9) for instance, the three acupoints used to treat shoulder bi syndrome by needle knife, and through traceability and researching constant structure, the acupoint position, insertion trace, manipulation and clinical significance of needle knife medicine were discussed. Accurate position is one of the characteristics of acupoints selection of needle knife medicine. As for the acupoints selection method, the mean of body surface localization is always used. The phanerous or palpable bone processes, muscles and tendons are taken as positioning marks; pressing areas where appear sour, numb, or distensible and other sensations is considered as the principle of press positioning. So acupoints position method is the combination of observation and palpation. Different insertion methods can effectively relieve the accretive bursae synovialis, tendon, joint capsule and the compressed nerve, so that shoulder bi syndrome is relieved.

Objective To explore the clinical features and long-term prognosis of juvenile idiopathic arthritis (JIA)in children, as well as particular quality of life associated with the clinical features and therapeutic options. Methods Seventy patients from August 1997 to August 2007 were retrospectively reviewed and survey was conducted using a questionnaire indicating quality of life(CHAQ questionnaires and CHQ questionnaire, adjusted appropriately) either by phone,letter or out-patient follow-up approach.The manner of correlation and logistic regression was used to analyze quality of life associated with the clinical features and therapeutic options. Results (l)The majority (74.3%) of patients were diagnosed as systemic onset JIA. The Cronbach Alpha coefficient of questionnaire is 0.9599, with a higher inernal consistency reliability. The scales validity also had the higher construction. Sixty nine cases with 76.8 percent of the score showed good quality of life. Quality of life in children less than 5 years old was significantly different from those more than 5-year old( P < 0.05). The rank sum test of single-use NSAIDs group and NSAIDs adding other medicine group suggested that the two groups had differences in quality of life( P = 0.026) .The correlation coefficient between the variables of time from onset to formal treatment and quality of life scores was 0.329( P < 0.05), and "walking"as the dependent variable for the regression analysis showed regression coefficient was 0.15( P = 0.016). The variable grip had the significant relationship with the "disease onset to regular treatment, the initial number of joint involvement" respectively. Conclusion Systemic oneset JIA is the most common type of JIA. Most of JIA patients have a good prognosis.The major factors which may cause the decline in the quality of life are age, duration without therapy after the disease onset,and the compliance to medication.To achieve a better prognosis,more aggressive therapy may be needed and individulized.

Mechanical ventilation plays an important role in the treatment of preterm infants,especially respiratory problems.With improvement in both antenatal and neonatal care and therapeutic strategies,premature babies are surviving more than ever.However,the incidence of bronchpulmonary dysplasia remains high which affects the clihical outcomes of premature infants.Non-invasive respiratory support techniques have been used in attempts to decrease lung injury and the complications of preterm infants.This review will focus on various ventilation modalities for managing preterm infants with respiratory failure and lung protective ventilation strategies to minimize lung injury in preterm infants.

Objective To determine the frequency of the cholesteryl ester transfer protein (CETP)-TaqIB polymorphism and investigate its relationship with plasma lipid levels and coronary hert disease(CHD). Methods Two hundred and thirty-eight patients with CHD (CHD group) and 203 age-matched controls( control group) were selected, the CETp-TaqIB mutation was detected by restriction fragment length polymorphism of the CETP gene. Results In the total subjects, the frequency of B1 and B2 alleles were 59.4%(262/441 ) and 40.6%( 179/441 ) respectively. Compared with that in control group, the frequency of CETP genotype BIBI was higher in CHD group [39.9%(95/238) vs 29.6% ( 60/203 ), P<0.05], and the frequency of B1B2 was lower in CHD group [44.1%(105/238) vs 53.7%(109/203), P< 0.05]. Compared with that in the B2 homozygotes, high density lipoprotein cholesterol (HDL-C) and apolipoprotein (apo)A I level were significantly lower in the B1 homozygotes [(1.19±0.36) mmol/L vs (1.38±0.39) retool/L,( 1.17±0.33 ) g/L vs ( 1.30±0.31 ) g/L, P<0.05]. The B 1 homozygotes was associated with higher degree of cononary stenosis than the B2 carriers (P<0.05 ). There was no significant association between CETP-TaqIB genotype and the risk of CHD (P=0.147). Conclusions CETP-TaqIB polymorphism affects the concentrations of lipaproteins. There are significant associations between the B1 homozygotes and lowerHDL-C and apo A I levels. The B1 allele is not an independent risk factor for CHD.
