OBJECTIVETo analyze the asymmetry of measurements in facial asymmetry patients with skull positioning posterior-anterior radiographs after orthodontic-orthognathic treatment.

METHODSPosterior-anterior cephalometric radiography and cephalometric analysis were performed in forty-five patients with different degrees of facial asymmetry. A single sample t-test was conducted to compare the asymmetry of measurements before treatment and individual normal occlusion. The measurement and reference values in facial asymmetry patients who underwent orthodontic-orthognathic treatment were summated by analyzing the correlation coefficient. The paired t-test was employed to compare the difference between the two groups before and after the treatment.

RESULTSFourteen measurements were significantly different before the treatment and individual normal occlusion (P < 0.05). Me[X] exhibited a higher correlation index of Ag[X] in forty-five cases. Twenty-eight patients showed the main asymmetry in the mandibular body, whereas fifteen patients in the ramus. Two patients showed the main asymmetry in both mandibular body and ramus. Fifteen measurements were significantly different before and after the treatment (P < 0.05).

CONCLUSIONFacial asymmetry is mainly concentrated in one-third of the surface, primarily manifested in the mandibular body. Orthodontic-orthognathic treatment is preferred when Ag[X] is greater than the minimum reference value of 11.31%, Go[X] is greater than 9.79%, and Me[X] is greater than 5.2 mm.

ObjectiveTo explore the relationships among atrial natriuretic peptide (ANP) and cerebral vasospasm (CVS) following subarachnoid hemorrhage (SAH) and hyponatremia.MethodsPlasma ANP levels and serum natrium and blood flow rate of intracal major arterial were assessed at different times (1 to 3 days, 7 days and 14 days after SAH) in 42 patients with SAH. Correlation analysis was carried out among plasma ANP, blood sodium level and blood flow rate of intracal major arterial.Results28 patients had CVS. Plasma ANP levels in CVS patients significantly elevated compared with non-CVS and control subjects (P<0.05). Hyponatremia in CVS patients also significantly elevated compared with non-CVS subjects (P<0.05). Plasma ANP level had significant negative relationship with serum natrium level at the 7th day and 14th day (r2=-0.778,r3=-0.653;P<0.01,P<0.05) in SAH patients. Plasma ANP level had significant positive correlation with middle cerebral artery mean flow velocity on the 7th day (r3=0.702,P<0.05) in SAH patients. Middle cerebral artery mean flow velocity had significant negative relationship with serum natrium level on the 7th day and 14th day (r2=-0.693,r3=-0.653 , both P<0.05) in SAH patients.ConclusionANP might cause hyponatremia following SAH and play an important role in pathogenesis of earlier period CVS.

Objective To detect the expression of metallothionein-3 (MT-3)mRNA in human esophageal squamous cell carcinoma. Methods Five cell lines of human esophageal cancer,TE-1,TE-13,TTN,ECA-109 (cell lines of esophageal squamous cell carcinoma) and OE33 (cell lines of esophageal adenocarcinoma),were used in this study. RT-PCR was employed to detect the expression of MT-3 mRNA. Peripheral blood monouclear cells from normal subjects were served as controls. Results Sequencing of RT-PCR product certified the gene of MT-3 mRNA. It was revealed by gel electrophoresis that there was expression of MT-3 mRNA in each cell line. The relative expression of MT-3 mRNA was 0.230?0.023,0.516?0.020,0.140?0.009,0.176?0.015 and 0.085?0.011 in cell lines of TE-1,TE-13,TTN,ECA-109 and OE33,respectively,significantly lower than that in controls (0.762?0.026) (P

OBJECTIVETo explore the effects and molecular mechanisms of rhein on reducing starvation-induced autophagic protein expression in renal tubular epithelial ( NRK-52E) cells.

METHODHank's balanced salt solution (HBSS) was used to induce NRK-52E cells to be in the state of starvation. After the intervention of HBSS for 0, 0.5,1, 2 and 6 hours, firstly, the protein expression of microtubule-associated protein 1 light chain 3(LC3 I/II), which is a key protein in autophagy, was detected. Secondly, the protein expressions of mammalian target of rapamycin (mTOR) and phosphorylated-mTOR Ser2448 (p-mTOR S2448) were examined. And then, after the co-treatment of rhein (5 mg x L(-1)) and HBSS (1 mL) without or with mTOR inhibitor, rapamycin (100 nmol x L(-1)), the protein expressions of LC3 I/II, mTOR and p-mTOR S2448 were tested, respectively.

RESULTHBSS could induce the up-regulation of LC3 II and the down-regulation of p-mTOR S2448 at protein expression level in NRK-52E cells. The co-treatment of rhein and HBSS could reversely regulate the protein expressions of LC3 II and p-mTOR S2448 in NRK-52E cells significantly. The co-treatment of rapamycin, rhein and HBSS could recover the level of LC3 II protein expression in HBSS-intervened NRK-52E cells.

CONCLUSIONHBSS induces autophagy in renal tubular epithelial cells by inhibiting mTOR signaling pathway activation. Rhein reduces the autophagic protein expression in renal tubular epithelial cells through regulating mTOR signaling pathway activation, which is the possible effects and molecular mechanisms.
