Objective To discuss the clinical features and treatment measures on patients with medium volume of supratentorial hypertensive cerebral hemorrhage in the elderly.Methods The clinical data of 57 patients with medium volume of supratentorial hypertensive cerebral hemorrhage aged ≥ 70 years were analyzed retrospectively.Results All of 57 patients,15 cases accepted medical treatment,42 cases were treated with minimally invasive operation for 1-26 (4.6 ± 6.5) h after onset.Three cases died in hospital,7 cases were transferred or gave up,6 cases lived as plant,8 cases were severely maimed,11 cases were moderately maimed,22 cases [38.6％(22/57)] recovered favorably.The main clinical characteristics of elderly patients:long history of hypertension,blood pressure fluctuation; atypical symptoms of increased intracranial pressure; more complications such as arrhythmia and pulmonary infection; most of family members of patients were pessimistic to treatment.Conclusions All factors should be thought over about the treatment of elderly patients with medium volume of hypertensive cerebral hemorrhage.Individual treatment is reasonable.Do not emphasize on early operation,minimally invasive operation can be helpful for patients.

Objectives To compare the efficacy and adverse effects of combining all-trans retinoic acid and arsenic triox-ide with or without anthracyclines on the treatment of childhood acute promyelocytic leukemia (APL) patients. Methods The retrospective study included 46 children as newly diagnosed APL from January 1st, 2001 to December 31st , 2012. Efficacy and adverse effects for different induction therapies and in high and low white blood cell (WBC) count subgroups were studied. Results In the non antharcycline containing group, 2 patients died during remission induction, and in the antharcycline containing group none of the patients died. No statistical difference was observed between the antharcycline containing group and the non antharcycline containing group in complete remission, the length of time to achieve molecular complete remission and minimal residual disease quantitative analysis at the end of the induction. The mean duration of high WBC count subgroup in the anthar-cycline containing group was shortened than that of the non antharcycline containing group (P<0.05). The recovery time of the abnormal coagulation was found similar between these two groups. Conclusions The use of antharcycline in induction therapy could shorten the duration of high WBC count and reduced the WBC count peak , thus reduces the risk of early death.

Objective To evaluate the value and feasibility of tissue mitral annular displacement (TMAD) in the assessment of left ventricular global and segmental longitudinal systolic function and synchronization in patients with hypertrophic cardiomyopathy.Methods The study population consisted of 39 on-obstructive hypertrophic cardiomyopathy (nHCM) patients and 39 healthy volunteers matched by gender and age.Left ventricular global and segmental longitudinal were measured by speckle tracking imaging(STI).The mitral annular displacement (MAD) (anterioseptal,posterioseptal,anterior,lateral,posterior and inferior sites,respectively),peak of time (PT) and left ventricular systolic dyssynchrony index (SDI) were measured by TMAD.The correlation between LSR and MAD was analyzed,and the parameters of MAD and SDI for tow groups were compared.Results The rate of effectively track segments of TMAD was significantly higher than that of STI(98.7％ vs 77.9％,P ＜0.001).There were high correlationship between segmental LSR and MAD(r =-0.784,P ＜0.001),and global and MADglobal (r =-0.897,P ＜0.001).Compared with the control group,MAD of six spots and MADglobal were significantly decreased (P ＜ 0.001,respectively),SDI was significantly increased(P ＜0.001).Conclusions TMAD is a sensitive and reproducible method for the assessment of LV longitudinal functionin patients with nHCM.

Objectives To investigate the inlfuence of polymorphisms of SLC19A1 80G>A, MDR1 exon26C>T and MDR1 exon21G>T/A on curative effect and adverse reaction of high-dose methotrexate in patients with acute lymphoblastic leukemia. Methods MALDI-TOF-MS technique was used to detect the polymorphisms of SLC19A1 80G>A, MDR1 exon 26C>T and MDR1 exon21G>T/A in 108 patients with acute lymphoblastic leukemia (ALL). The relationship of genetic polymorphism, survival rate and toxicity was analyzed. Results The 36-month event-free survival was not related to any polymorphisms of MDR1 and SLC19A1. Patients with mutant types of MDR1 exon26C>T and MDR1 exon21G>T/A showed a much higher MTX plasma levels at 24 hours and higher incidence of hepatic injury (P<0.05). Conclusions The genetic polymorphism of MDR1 exon26>T, MDR1 exon21G>T/A has a large inlfuence on hepatic toxicity and plasma concentra-tions of MTX.

Background In recent years,with the contiunous progress of the refractive surgery,the operation skill of phakic intraocular lens(PIOL)implantation for correcting extreme high myopia,astigmatism,farsightedness have made greater progression,and its security,effectiveness in clinical attract much more attention. Objective This study was to evaluate the efficacy,safety and stability of Toric Implantable Collamer Lens(TICL)for extreme high myopic astigmatism. Methods This retrospective case series included 33 eyes of 27 patients from May 2008 to February 2009.A TICL was intraocularly implanted via a 3 mm clear corneal incision after paraocular anesthesia.Patients were examined preoperatively and followed-up at 1 day,1 week,1 month,3,6,12 and 18 months postoperatively.The examinations included uncorrected visual acuity,best corrected visual acuity(BCVA),slit lamp examination,refraction,intraocular pressure,endothelial cell morphometry,etc.The written informed consent was obtained from each patient before any medical procedure. Results The uncorrected visual acuity in 96.97% eyes was equal or improved after operation in comparison with BCVA of preoperation.The spherical refraction was within-1.00 D-+0.25 D.The cylinder refraction was within-1.00 D-0 D.The axial deviation of TICL within 10 degree was 93.94%(31/33).No significant differences were found in the intraocular pressure and endothelial cell morphometry between preoperation and postoperation(intraocular pressure:F=3.35,P=5.49;endothelial cell morphometry:t=1.835,P=0.082).The visual acuity and refraction were stable during the follow-up.Astigmatic axial rotation required surgical intervention on one eye.One eye occurred high intraocular pressure because of bigger TICL diameter.The intraocular pressure returned to normal after TICL was exchanged.No cataract occurred during the follow-up duration. Conclusion TICL implantation appears to be an effective,safe and reliable method for extreme high myopic astigmatism.

AIMTo evaluate whether protein phosphorylation and dephosphorylation in nuclei play roles in the development of myocardial hypertrophy, distribution of protein kinases and phosphatases in cell fractions were determined.

METHODSThe model of hypertensive rat was established by abdominal aortic constriction. Velocity and isopyknic gradient centrifugation was employed to fractionate rat myocardium to membrane, cytosol and nuclei. Enzymatic methods were employed to determine kinases and phosphatases.

RESULTSCompare with control group, the activity of CaMK increased by 101.1% (P < 0.01) and 40.16% (P < 0.01) respectively in nuclear and membranous fractions, changed without significance in cytosolic fraction; the activity of calcineurin in nuclei increased by 43.57%, (P < 0.05), lightly changed without significance in membranous and cytosolic fractions.

CONCLUSIONNuclear translocation of CaMK and calcineurin, might play important roles on overload-induced cardiac hypertrophy.

Phage antibody display technology is currently the most widely used in vitro antibody screening technology,which uses bacteriophages as a vector,and inserts exogenous antibody library genes into phage capsid protein genes,and expresses the capsid protein on the phage surface while also displays the antibody protein.Antibody drugs play an important role in tumor immunity and microbial immunity due to their targeting advantages,which is also an important driving force for them to become a hot spot in the field of pharmaceutical research and development.Therefore,this article reviews the background,basic principles,antibody library types and antibody fragment types of phage display technology,and looks forward to the latest progress and application prospects of fully human antibodies.

OBJECTIVETo compare the therapeutic effects of video-assisted thoracoscopic extended thymectomy (VATET) and transsternal extended thymectomy (TET) for myasthenia gravis (MG).

METHODThis study included 21 patients undergoing VATET through the "three holes" approach on the right chest and 32 undergoing TET with sternum dissection. The thymus was excised and the anterior mediastinum adipose tissue removed in both groups.

RESULTSVATET was associated with reduced intraoperative blood loss and longer operative time without the use of postoperative analgesics; very few patients were admitted into the intensive care unit (ICU), showing significant differences from the TET group (P<0.05). No significant difference was found between the two groups in tracheal tube removal time, length of stay in ICU, closed thoracic drainage removal time, and postoperative hospital stay, total hospital stay, postoperative complications, total hospitalization costs, or the rate of remission and improvement (P>0.05).

CONCLUSIONSCompared with TET, VATET requires only a small incision without leaving metal foreign body in the body, and the patients experience less postoperative pain and rapid recovery, with similar mid- and long-term clinical outcomes.

BACKGROUNDPeutz-Jeghers syndrome (PJS) is an autosomal dominantly inherited disease. STK11/LKB1 gene germline mutations have been identified as responsible for PJS. In our study, we investigated the molecular basis of PJS and evaluated correlation between the STK11 mutations and the Chinese population.

METHODSWe collected three pedigrees of PJS and screened the 9 exons and their flanking intronic sequences of STK11/LKB1 gene in the probands and normal individuals in the families using polymerase chain reaction (PCR) and direct sequencing.

RESULTSSequencing of the STK11 gene in the probands of 3 families revealed two novel mutations (c180C-->G and c998-1002delGCAGC) in exon 1 and exon 8, respectively. The mutation of c180C-->G resulted in a premature termination codon. The other mutation, a deletion of five nucleotides (998-1002delGCAGC) in exon 8, predicted to generate a translational frameshift and a termination at codon 1070.

CONCLUSIONSThe growing number of mutations in PJS pedigrees suggests the molecular basis of PJS. STK11 gene mutation can be detected in most patients with PJS.
