Objective To investigate the protection effect of dexmedetomidine against H2O2 injury in Human renal tubular epithelial cells(HK-2 cells). Methods HK-2 cells cultured in vitro were randomly divided into four groups(n = 24): control group, dexmedetomidine pretreatment group, H2O2 injury group, H2O2 injury +dexmedetomidine pretreatment group. Cell viabilities were measured by MTS assay, cell apoptosis were detected using flow cytometry, and expression of HIF-1α protein was quantified by western blot. HK-2 cells were divided into 8 groups by combining with three treatment factors such as PI3K inhibitor LY294002, dexmedetomidine and H2O2 injury. MTS assay was used to detect cell viability and western blot was used to quantify protein expression of HIF-1α,Bcl-2 and Bax after treatment in each group. Results Dexmedetomidine significantly increased the level of HIF-1α、 Bcl-2 in HK-2 cells after H2O2 injury, thus improved viabilities and reduced apotosis of cells. Moreover, effect on H2O2 injury cells of Dexmedetomidine was reversed by PI3K inhibitor LY294002. Conclusion Dexmedetomidine could protect against H2O2 injury by up-regulating HIF-1α expression through activating PI3K/Akt/mTOR signaling pathway in HK-2 cells.

Objective: To study the cause of rapid thrombocytopenia and organ hemorrhage in congenital heart disease (CHD) patients after interventional occlusion. Methods: A total of 665 CHD patients received interventional occlusion in our hospital from 2011-01 to 2015-12 were enrolled. The patients were divided into 3 groups according to the defects: Atrial septal defect (ASD) group,n=100, Ventricular septal defect (VSD) group,n=100 and Patent ductus arteriosus (PDA) group,n=465. Pre- and post-interventional occlusion platelet levels, the relationship between PDA occluder diameter and platelet counts were compared. Pressure difference between both sides of occluder was randomly measured in a part of patients including 50 in ASD group, 50 in VSD group and 102 in PDA group. Based on occluder diameter, the 102 PDA patients were further divided into 2 subgroups: Giant PDA,n=42 and Medium-small PDA,n=60; pressure differences between both sides of occluder were compared between 2 subgroups. Results: No severe thrombocytopenia and organ hemorrhage occurred in ASD group or VSD group. PDA group had 36/465 (7.74%) patients with severe thrombocytopenia, 18 (3.87%) with organ hemorrhage and all of them occurred in giant PDA subgroup; the diameter of PDA occluder was negatively related to post-operative to platelet counts (r=-0.659,P=0.001). For pressure difference on both sides of occluder, compared with prior operation, PDA group showed increased systolic and diastolic pressure differences and increased mean pressure difference at immediately post operation, allP< 0.05; systolic pressure difference in VSD group was (56.57±15.33) mmHg, in Medium-small PDA subgroup was (58.33±26.65) mmHg and in Giant PDA subgroup was (94.66±27.62) mmHg which was much higher than those in VSD group and Medium-small PDA subgroup, allP<0.01. Conclusion: Rapid thrombocytopenia and organ hemorrhage in CHD after interventional occlusion only happened in giant PDA patients. High pressure difference formed high-speed ifltration blood lfow which may cause scouring damage on platelets and it was the main reason for thrombocytopenia occurrence.

Objective To discover the mutation of ADAR gene in a pedigree with dyschromatosis symmetrical hereditaria(DSH). Methods We investigated this family and collected blood samples of the individuals in this family. Mutation screening was carried out by PCR and direct sequencing. The allele specific primer was designed for the mutation point, and allele-specific PCR was carried out on the patients, normal family members and 40 normal individuals. Results A single nucleotide deletion (c.1642 delC) was identified in exon3 of ADAR gene in the patients of this family. This mutation was not detected in the normal family members and in any of the control individuals. Conclusion This single nucleotide deletion was responsible for the disease in the family.

Objective To compare clinical outcome of microvascular decompression (MVD) and percutaneous balloon compression (PBC) by using a prospective cohort study in order to provide a reliable evidence for the clinical decision-making. Methods Patients with trigeminal neuralgia hospitalized at Hangzhou First People′s Hospital in 2010 were chosen as database for cohort study. The patients were divided into MVD group (30 cases) and PBC group (30 cases). The clinical efficacy was followed by independent observers for 36 months after surgery. Chi-square test for hierarchical data, t test for quantitative data, and Kaplan-Meier plot for clinical outcomes were applied in the research. The endpoint was follow-up accomplishment or severe occurrence. Results Sixty patients were included in the research till the endpoint. The general records before surgery were almost the same with the literature records. By comparing painless period, mild and severe relapse, MVD group was superior to PBC group (P < 0.05). As for the painless survival period, MVD group was 96.7% of pain free after 1 year, 93.3% after 3 years, while PBC group was 90.0% after 1 year and 83.3% after 3 years. Regarding 3 years of follow-up, the relapse seemed occurred after 1 year in both groups. Conclusions As a curative and nondestructive procedure , MVD is more effective and has longer lasting pain free period , which should be considered as the first choice of treatment for trigeminal neuralgia in healthy people.

Meridians in human body were classified as white meridian and black meridian according to Tibetan medicine.Season and environment,improper diet,toxic heat and trauma were recognized as main reasons damaging the white meridian in Tibetan Medicine,leading to the emerge of white meridian disease induced by Long (one of the three factors) and blood disorder.White meridian disease in Tibetan medicine involved a series diseases,such as many clinical diseases,due to the damage of white meridian system caused by pathogenic factors.Stroke also belonged to white meridian disease.Drugs and treatments were selected based on the nature of disease such as cold and heat,onset,thelocation of disease and the three factors (Chi Ba,Long and Pei Gen).It was the fundamental principle of the treatment rules of white meridian disease in Tibetan medicine,namely,prescribing medication with the rule of diagnosis and treatment,comprehensive analysis of the causes of diseases and mastering the change law of diseases and syndromes in clinic.

Objective To describe the surgical technique and outcomes of arthroscopic reconstruction anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) and repair of the injured posteromedial complex (PMC) or posterolateral complex (PLC) structures of the knee joint in treatment of multiple ligaments injuries of knee. Methods From March 2005 to May 2007, 43 patients with multiple ligaments injuries of knee underwent arthroscopic reconstruction. Twenty-four patients were treated with arthroscopic reconstruction of combined ACL and PCL with allograft tendons and augmentation of PMC. The other 19 patients were treated with repair the PLC in addition to reconstruction of ACL and PCL. The International Knee Documentation Committee (IKDC) and Lysholm knee score were used for function evaluation. Results All patients were followed up for 24 to 48 months with an average of 33.10±9.65 months. The stability recovered when stress was applied to the knee at 0° and 20° of flexion. According to IKDC there was a significant improvement from severely abnormal (graded D) in 43 cases before surgery to normal (graded A) in 29 cases (67%), nearly normal (graded B) 11 cases (26%) and abnormal (graded C) 3 cases (7%) at follow-up. The average Lysholm score of the all cases were 46.7±4.2 and 89.6±2.8 before operation and at final follow-up, respectively (t=8.563, P＜0.01). Conclusion Excellence clinical results and good stability were achieved with arthrescopic reconstruction of ACL and PCL combined with repair or augmentation of the PMC and PLC simultaneously.
