Aim To observe the protective effect of quercetin on rat cardiomyocyte apoptosis induced by adriamycin and explore its possible mechanism.Methods Cultured neonatal rat cardiomyocytes were randomly divided into six groups:normal control group, adriamycin group,quercetin control group, adriamycin+quercetin(25,50,100 ?mol?L-1)groups. The activity of LDH was detected by chromatometry, the cardiomyocyte viability was measured by MTT, the ultrastructure of cardiomyocyte was observed by electron microscope, the expression of protein Bcl-2 and Bax was analyzed by immunocytochemical, and the mRNA and protein of caspase-3 were detected by RT-PCR and Western blot respectively.Results Compared with the control group, the activity of LDH was increased but the viability of cardiomyocyte was decreased; the expression of Bax and caspase-3 was up-regulated while Bcl-2 was down-regulated in ADR group.Compared with ADR group, the above changes were lightened in adriamycin+quercetin groups. But the quercetin control group, in which cultured myocardial cells only exposed to quercetin without ADR, had no obvious changes.Conclusions Quercetin significantly inhibits the apoptosis induced by ADR in the cultured myocardial cells. Its mechanism is involved in the apoptosis-related pathways, including caspase-3, Bax and Bcl-2.

Objective To explore the effects of lamotrigine on the cognitive function and the quality of life in epilepsy patients.Methods This was a prospective study and 91 newly diagnosed epilepsy patients were enrolled.The neuropsychological tests score and the quality of life in epilepsy inventory(QOLIE-31) were obtained before and after the treatment with lamotrigine.A battery of neuropsychological tests comprised the auditory verbal learning test(AVLT), the logical memory test(LMT), the digital symbol test(DST), the stroop color word test(SCWT), the trail making test(TMT), the verbal fluency test(VFT), the WAIS block design test(WBDT), the WAIS digital span test(WDST)and the Boston naming test(BNT). Results The repeated assessments in the patients taking lamotrigine were associated with significant improvements in many domains.The greatest changes were observed in the immediate and delayed recall of AVLT, DST, the time consuming of SCWT card C and TMT test A and B, the immediate and delayed recall of LMT, VFT, WBDT and BNT.For the quality of life, significant improvements were recorded in the fields of the seizure worry(38.81?16.06 vs 45.68?15.18), the overall quality of life(59.12?13.50 vs 64.99?13.33), the social function(64.59?25.14 vs 69.41?22.70)and the self-health evaluation (71.18?13.73 vs 76.75?11.30).Conclusion Improvements of the cognitive function and the quality of life can be observed in the initial period of medication with lamotrigine in epilepsy patients.

AIMTo analyze the relationship between autosomal aberrations and testicular dysgenesis or spermatogenic arrest in Chinese patients and to map the corresponding regions on each autosome in regard to the recorded aberrations accompanying these distubances.

METHODSOne hundred and nineteen cases of aberrant karyotypes with testicular dysgenesis, azoospermia or oligozoospermia reported in five Chinese journals and one monograph were analyzed. For each autosome, the type and frequency of chromosomal aberrations were counted and the regions corresponding to the disturbances were mapped out.

RESULTSChromosomes 13, 14, 9, 21 exhibited a high frequency of aberration and bands 14q11 and 13p11 were the two regions showing the highest linkage to testicular dysgenesis or infertility. The frequency of chromosomal aberrations was higher in bands 9p11 and 22q than in others.

CONCLUSIONAutosomes 13, 14, 9 and 21 in the order of importance play a critical role in testicular development and spermatogenesis and other autosomes may also contribute; the following regions, 14q11, 13p11,9p11, and 22q, are of high significance.

BACKGROUND:Tissue factor (TF) is the initiation factor of the extrinsic coagulation pathway, and plays a critical role in the process of thrombosis. This study aimed to investigate the expression of TF and to explore their clinical effect on the pulmonary artery after acute pulmonary thromboembolism. METHODS:Thirty-four Japanese white rabbits (Level II animals) supplied by Tianjin Medical University were randomly assigned into:group A, specimens of the pulmonary artery taken 3 hours after pulmonary embolism (n=8); group B, specimens of the pulmonary artery taken 8 hours after pulmonary embolism (n=8); group C, specimens of the pulmonary artery taken 24 hours after pulmonary embolism (n=8); and control group, pseudo-operations performed without injection of autologous blood clots (n=10). The animal model of pulmonary thrombo-embolism was established by injection of autologous blood clots into the jugular vein through a 5F catheter, and was confirmed by digital subtraction angiography. The mRNA expression of TF in different parts of the pulmonary artery was accessed by RT-PCR. Theq test was used if there was a significant difference in a given continuous variable among the three groups assessed by ANOVA. The experiment equipment was supplied by the State Key Laboratory of Experimental Hematology, Institute of Hematology and Blood Diseases Hospital, the Chinese Academy of Medical Sciences and Peking Union Medical College. RESULTS:The TF expression in the specimen adjacent to emboli was stable at 3, 8 or 24 hours after embolism. The mRNA expression of TF at 3 and 8 hours after embolism was lower in the specimens taken from the distal end of the morbid pulmonary artery than those adjacent to emboli. While at 24 hours after embolism, there were similar mRNA levels in specimens either adjacent or distal to emboli. CONCLUSION:The high level of TF expression in pulmonary artery tissue adjacent to emboli could lead to locally increased coagulation activity, indicating the necessity of initiating anti-coagulation treatment as soon as possible after acute pulmonary embolism.

OBJECTIVETo explore the effective techniques for correction of lacrimal groove and palpebromalar groove deformity in the middle-aged and old people.

METHODThe lacrimal groove and palpebromalar groove deformity was corrected by the techniques of transcutaneous orbital fat releasing and pedicle orbital fat flap filling.
