Chinese Journal of Primary Medicine and Pharmacy 2006;0(08):-
Objective To explore the clinic effects in duplication blepharoplasty with the multiple tiny inci- sions.Methods The line of drooping blepharon was set in routine in 183 patients,the incisions with 3~4mm long would be made in middle and the both canthi sides on the line,cutting 1.5~2mm long flaps of the muscle orbicularis oculi off in the down rim of the incisions.Excessive fats also released form the orbital septum in patients with swelling blepharon.Then put up the muscle tendon of blepharon and sutured with the slcin on the up rim of tarsal plate.Results The reaction of tissue after operation was very light,swelling in the incision could disappear after 7~23 days and the incision scars weretiny and unclear,tbe double-fold eyelids had a good appearance in long time.Con- clusion It is an effective and usable procedure to the patients without skin loosening or serious swelling blepharon by means of multiple tiny incisions in blepharoplasty.

Objective To select the calibrator for the conventional measurement system of serum a-Amylase (Amy).Methods The Amy levels of forty frozen serum samples were detected by the IFCC reference method (reference system),the conventional system A which used the Bioassay routine reagent and Randox calibrator,and was calibrated by the Roche PNPG7 method,and the conventional system B which used the Bioassay routine reagent and Randox calibrator,and was calibrated by the Rondox liquid stable PNPG7 method,respectively,and the acceptability of the two conventional systems was evaluated.Results The regression equations of the measurement values between the IFCC reference method and the conventional systems A and B were Y =0.964X +0.376 and Y =1.095X + 3.131,respectively.Among them,X and Y represented the results of the IFCC reference method and the conventional system,respectively.Compared with the IFCC reference method,the results of the conventional system A was reliable.Condusion With the guidance of the IFCC reference method,the domestic biochemical reagents matched with the suitable calibrators may provide the acceptable results.

Objective To explore the effects of low frequency electric stimulation on the clinical manifes- tation and its influence on the level of plasma Endothelin (ET),atrial natriuretic peptide (ANP),thromboxane B_2 (TXB_2),angiotensinⅡ(AngⅡ),Calcitonin Gene Related Peptide(CGRP) and Neuron-specific Enolase(NSE) and its clinical significance in the patients with vertebrobasilar insufficiency(VBI). Methods One hundred and tewenty cases of VBI patients were randomly divided into two groups:a treatment group and a control group.Both groups received routine drug treatment.The treatment group (n=60) was also treated with low frequency electric stimulation at bilateral mastoid processfes in addition.The improved rate of the clinical symptom,the plasma level of ET,ANP,TXB_2,AngⅡ,GRP and NSE were observed after treatment. Results The patients treated in the treatment group had significantly better outcome than the control group in terms of symptom relief.The effective rate was 87.93% and 67.80% in the treatment group and control group,respectively(P

Objective To exPlore the effect of mammalian target of raPamycin ( mTOR ) inhibitor eVerolimus on radiosensitiVity of human non_small cell lung cancer cell line in vitro by using eVerolimus to inhibit mTOR signaling Pathway of A549. Methods Human non_small cell lung cancer cell line A549 was subjected to radiation alone or in combination with eVerolimus treatment. The 50%inhibition concentration ( IC50 ) of eVerolimus in A549 cells was detected by methylthiazol tetrazolium ( MTT) assay in vitro. EVerolimus at the 20%inhibition concentration ( IC20 ) was used to Pretreat A549 cells for 24 h. Cells were then irradiated by X_ray with 2,4,6,8 Gy. The cell surViVal fraction was comPuted by clone formation. Cell surViVal curVe was fitted by multitarget one_hit model, and mean lethal dose ( D0 ), dose quasithreshold ( Dq ), surViVal fraction at 2 Gy ( SF2 ), and sensitization enhancement ratio (SER) were calculated. The exPression ofγ_H2AX was determined by Western blotting and then the relatiVe gray Values were analyzed. Results EVerolimus significantly imProVed the sensitiVity of A549 cells to radiation. The D0 , Dq and SF2 of eVerolimus+irradiation grouP were significantly lower than those of irradiation grouP. The SER was 1. 36. The residual amount of γ_H2AX Protein in the eVerolimus + irradiation grouP was significantly higher than that of the irradiation grouP. Conclusion EVerolimus inhibiting mTOR signaling Pathway can increase the radiosensitiVity of A549 cells.

Objective To investigate the possibility and feasibility of the whole genome microarray scanning technique in clinical cytogenetic diagnosis of an uncertain karyotype and mentally retarded child. Methods The karyotype analysis of the mental development delayed child was 47, XY+mar. Genomic DNA was extracted from the peripheral blood and the whole genome microarray scanning technique was used to analyze the derivative chromosome. Results The whole genome microar-ray scanning technique indicated the derivative chromosome fragment had originated from 9p13.1-p24.3. Conclusions Com-paring to conventional cytogenetic analysis methods, the whole genome microarray scanning technique is of high resolution, high-throughput and high accuracy, which can detect the submicroscopic chromosomal aberrations and replace the conven-tional karyotype analysis.

This study is to explore characteristic indexes in evaluation criteria for rat skin anaphylactoid test comparing skin blue spot OD values at the treated position and the control position in the same animal. Common contrast agents, traditional Chinese medicine injections and injections' active pharmaceutical ingredients or excipients in the existing clinical anaphylactoid reaction reports were taken as test drugs in the rat skin anaphylactoid test to define the K value: K > 2 represents positive anaphylactoid reaction, 1.2 ≤ K ≤ 2 represent doubtable anaphylactoid; K < 1.2 represents negative anaphylactoid reaction, which were taken as the criteria for evaluating anaphylactoid of tested drugs. The evaluation result and that for classic criteria were compared to study the applicability of K value. According to the comparison, K value, as the evaluation criteria in the rat skin anaphylactoid test, can more truly reflect the actual situation of skin aizen and minimize the error caused by animal individual factors. Compared with positive and negative two-level criteria for blue spot diameter, K value's positive, doubtable and negative three-level criteria are more objective and accurate. Therefore, K value can be used as the evaluation criteria in the rat skin anaphylactoid test.

Objective:To explore the development characteristics of empathy in adolescents and the relations with aggression.Methods:With multistage stratified random sampling method,15 738 middle school students were selected from 5 provinces across China.The Buss-Warren Aggression Questionnaire Revised in China (BWAQ-RC) and Interactional Reactivity Index (IRI-C)was used to measure adolescents'aggression and empathy.Results:Girls had higher level of empathy than boys (P <0.001).Age and gender were interacted in predicting empathetic con-cern (P <0.001).Perspective taking was significant negative predictor of indirect aggression,physical aggression, hostile and angry (P <0.001),while empathetic concern was significant positive predictor of indirect aggression, verbal aggression,hostile and angry (P <0.001).Empathy was divided into 4 class used the K-Means clustering a-nalysis,namely,low empathy class,high perspective taking class,high empathetic concern class,high perspective taking and empathetic concern class.In contrast to other classes,individuals in low empathy class were more likely to involve in physical aggression (P <0.05),and individuals in high level of perspective taking and empathetic con-cern class were related with less physical aggression and elevated verbal aggression (P <0.05).Individuals in high empathetic concern class exhibited more indirect aggression,hostile and anger than other subgroups (P <0.05). Conclusion:The unbalance development of the two components of empathy may be closely correlated with different conduction of aggressive behaviors.
