OBJECTIVEThis study is to evaluate the soft tissue change of Angle's Class II division 1 malocclusion patients with vertical growth pattern after tooth extraction orthodontic treatment, and to provide experimental results to help to make orthodontic treatment plan and treatments.

METHODS38 Angle's Class II division 1 malocclusion patients with vertical growth pattern and with tooth extraction orthodontic treatment were included in this study. The pre- and post-treatment cephalometric X-rays were made and 26 measurement items were measured. The change value of pre- and post-treatment, youngsters and adults were compared.

RESULTSTUL-EP, TLL-EP, upper and lower lip position, Stoms-Stomi, U1-Ptm were reduced after treatment. Upper lip sulcus and flange thickness, upper and lower lip length, upper and lower lip inclination angle, nasolabial angle, Z angle, mentolabial sulcus inclination angle were enlarged after treatment. The upper lip sulcus thickness, lower lip length and A'-Ptm of adolescent were enlarged, but adult were on the contrary. The change of upper lip length, mentolabial sulcus inclination angle and U1-Ptm between adolescent and adult was statistically different.

CONCLUSIONThe best treatment period of patients with Angle's Class II division 1 malocculsion with vertical growth pattern was in the rapid growth and development period of adolescent.

This study aims to assess if adverse drug reactions (ADRs) to parenterally administered salvianolate are allergic in origin. Hospital information system (HIS) data from 20 hospitals in China were used to carry out a retrospective nested case control design study. Included were patients who received dexamethasone for suspected allergic reactions after receiving parenterally administered salvianolate. These were compared with non-allergic reaction people. Single factor logistic regression and multiple factor logistic regression were used to analyze data. Condition on admission, allergic history, dosage, disease status and drug combinations were taken into account in cases of suspected allergic reactions. After analysis in two subgroups we found that the condition on admission had a significant effect, P values was < 0.000 1 on suspected cases of allergic reactions in the first subgroup analysis. For the second subgroup analysis, we found condition on solvents had a significant effects, P values was 0.005 1 on suspected cases of allergic reactions. We also found that using other four injections at the same time as parenterally administered salvianolate could be risky factors in suspected cases of allergic reactions. For the second subgroup analysis combining using three injections could increase risks. However, further research for verification is required. This study can provide guidance for safe clinical practice in using parenterally administered salvianolate.

Objective To analyze the impact factors for early renal damage in type 2 diabetic patients by the classification tree model.Methods A total of 601 patients with type 2 diabetes were enrolled.According to glomerular filtration rates and urine albumin quantification,the patients were divided into type 2 diabetes group (418 cases) and early diabetic renal damage group (183 cases).The clinical data of the patients were recorded to analyze the main influential factors for the microalbuminuria of type 2 diabetic patients using the Exhaustive CHAID classification tree algorithm.Results Six important explanatory variables were screened out by the classification tree model from the 34 candidate variables related to early renal damage,including fibrinogen,history of hypertension,retinopathy,Cys C levels,SBP and peripheral neuropathy.Elevated fibrinogen was the main factor.Conclusion The classification tree model can analyze the major influential factors of early renal damage in type 2 diabetic patients effectively,and it can help develop the prevention and treatment methods.

Objective To investigate the effect of advanced glycation end products (AGEs) on the disruption of tight junctions in rat glomerular endothelial cells (rGEnCs) and the role of renin-angiotensin system (RAS) in this pathological procedure.Methods Primary cultured rGEnCs were incubated with AGEs at concentrations of 20 mg/L,40 mg/L and 80 mg/L,for 6 h,12 h and 24 h respectively.The cells were treated with captopril (1 mmol/L) or valsartan (10 μ mol/L)to block RAS.The endothelial permeability was investigated by transendothelial electrical resistance and the flux of fluorescein isothiocyanate-conjugated bovine serum albumin.The expression of AGEs receptor (RAGE),tight junction proteins [occludin,claudin-5,junctional adhesion molecules A (JAM-A) and zona occludens-1 (ZO-1)]and RAS components [angiotensinogen,renin and angiotensin Ⅱ type 1 receptor (AT1)]were detected by Western blotting.Immunofluorescence was used to demonstrate the disruptions of the tight junction proteins.The activity of angiotensin converting enzyme (ACE) was evaluated by UV spectrophotometry.Angiotensin Ⅱ (Ang Ⅱ ) was measured by enzyme immunoassay.Results The monolayer permeability,the expression of RAGE,the activity of ACE,the concentration of Ang Ⅱ and the expression of AT1 of rGEnCs were increased after induced by AGEs.Meanwhile,AGEs decreased the expression of occludin,claudin5 and JAM-A and induced disruption of tight junction proteins.Pretreatment with anti-RAGE antibody (100 mg/L),captopril or valsartan could attenuate the detrimental effect of AGEs.Conclusion The changes of permeability induced by AGEs in glomerular endothelial cells are partly mediated by RAS through RAGE.

Objective To explore the effect of high glucose on the renin-angiotensin system (RAS) in rat glomerular endothelial cells and its probable mechanism.Methods Rat glomerular endothelial cells were stimulated by culture medium containing 5 mmol/L or 30 mmol/L glucose (with or without pre-treatment of captopril and chymostatin) for 12 h,24 h,48 h,72 h.ELISA,real-time PCR,Western blotting and confocal immunofluorescence microscopy were employed to examine the follows:the angiotensin Ⅱ (Ang Ⅱ ) concentration in cell lysate and the culture medium; the mRNA levels of angiotensinogen and renin; the protein levels of angiotensin Ⅱtype 1 receptor (AT1R),angiotensin Ⅱ type 2 receptor (AT2R),renin and angiotensinogen in cell lysate; localization of intracellular AT1R,AT2R and renin.Results Exposure to high glucose for only 12 h or 72 h resulted in a significant increase of Ang Ⅱ levels in the culture medium compared with control cells (P＜0.05),but only exposure to high glucose for 72 h resulted in a significant increase of Ang Ⅱ levels in the cell lysate compared with control cells (P＜0.05).However,exposure to high glucose for 24 h or 48 h had no effects on Ang Ⅱ levels in the cell lysate or culture medium.The captopril and chymostatin were able to antagonize high glucose induced Ang Ⅱ generation when exposure time was 72 h but not 12 h.Exposure to high glucoseincreased the mRNA level of angiotensinogen,but reduced the level of renin mRNA,meanwhile angiotensinogen protein increased,and AT1 protein reduced,but protein levels of AT2R and renin were unchanged.However,the transformation of AT2R from the cell nucleus to cytoplasm was observed.Conclusions High glucose can activate the local renin-angiotensin system in rat glomerular endothelial cells,and the probable mechanism may contribute to ACE and non-ACE pathways.The effects of high glucose on glomerular endothelial cells may also involve in the substrate and receptors of Ang Ⅱ.
