Objective To analyse the dynamic changes of cardiac diseases over the past 30 years. Method All hospitalized patients of internal medicine department over the past 30 years in the 2nd Xiangya Hospital of Central South University were analyzed in order to understand the dynamic changes of cardiac diseases. Results The results showed the proportion of the heart diseases to all medical diseases was gradually increased during the past three decades. The constitution ratio of the classification of the heart disease was also changing continuously and progressively, with coronary heart disease ranking the first and, in contrast, rheumatic heart disease the second since 1980s. Meanwhile, the number and the proportion of the patients with cardiomyopathy and arrhythmias of unknown causes were increased. Anemic heart disease and cardiovascular syphilis had been wiped out since 1980s and 1990s respectively. Conclusion Classification of cardiac diseases changes gradually and continually during the past 30 years.

Objective To evaluate the performance of Cys C results among two detection system.Methods The particle-enhanced immunonephrometic assay was used in Dade Behring BNII. Immunoturbic assay was used in Hitachi 7170 to evaluate the JING' YUAN reagents.We compared the precison,linearity,interference,correlation,and calibrators agreement with Dade Behring BNII.Results The total CV of the samples that contain 0.6-5.0 mg/L was less than 10%.The Dade Behring and JING'YUAN method showed good linearity.Haemoglobin(10 g/L),Bilirubin(300 mg/L), Vitamin C(5 g/L)in the tested sample had no significant interference in the assay(interference 0.05) between JING' YUAN and Dade Behring reagents.Values were slightly lower than that from the Dade Behring BNII method,the mean bias was-0.16.The bias range was 1.1%-23% between JING'YUAN and Dade Behring for one sample.Conclusions The precision,linearity and interference test were suitable for routine Cys C measurement on automated biochemistry analyzer,but results has bias.

To discuss the effective method of decreasing the postoperative recurrence rate of recurrent pterygium.
●METHODS:Totally 126 cases (126 eyes) with recurrent pterygium were randomly divided into A group (56 cases) and B group ( 70 cases ). Group A was treated by pterygium conjunctive reverse transplantation combined with amniotic membrane transplantation, group B was treated by amniotic membrane transplantation. The followed-up time after surgery was 6-24mo.
●RESULTS:ln group A, postoperative 5-7d (average 5. 62± 1. 38d), cornea epithelium was repaired. ln group B, postoperative 7- 10d ( average 7. 38 ± 1. 12d), the corneal wound was healed. There was statistical significant difference between two groups (t = 4. 307,P<0. 05). Three cases recurrence were noted in A therapeutic group (56 cases), the recurrent rate was 5. 4%; Twelve cases recurrence were noted in B compared group (70 cases), the recurrent rate was 17. 1%. There was statistical significant difference between two groups(P<0. 05).
●CONCLUSlON: lt is suggested that pterygium conjunctive reverse transplantation combined with amniotic membrane transplantation is effective in the treatment of recurrent pterygium.

Objective To explore a better method to repair cervical cicatricle contracture deformity.Methods The cervicai cicatrical contraction deformity was repaird by the cervico-shoulder island skin flap with blood supply crossing and abundant anastomotic branches of the neck-shoulder blood vessels. After removing the cervical scar, the flaps were designed according to the size of the wound to be repaired, and the clinical anatomy of crossing and abundant anastomotic branches of the neck-shoulder blood vessels. The secondary wound of donor site was closed directly if the donor region was small, or closed by skin graft. Results Sixteen patients in this clinic were operated with this method, and venous return dysfunction occurred in 1 case, but blood circulation was improved after treatment. All the flaps survived with good appearance and texture. The extensive flap was created and transferred to the anterior neck by one stage without pre-expansion which met some patients'requirement of repairing cervical cicatricle contracture deformity. Conclusion The cervico-shoulder island skin flap, with abundant blood supply, is a new method to repair cervical cicatricle contracture deformity.

The PET tracer 5-([11C]methyloxy)-L-tryptophan (5-(11)CMTP) was prepared by nucleophilic fluorination and alkylation reaction via a two-step procedure in order to develop specific tumor probe. The biodistribution and microPET imaging of 5-(11)CMTP were executed. The results unveiled that the overall radiochemical yield with no decay correction was (14.6 ±7.2) %, the radiochemical purity was more than 95% and high uptake and long retention time of 5-(11)CMTP in liver, kidney and blood were observed but low uptake in brain and muscle were found, furthermore, high uptake of 5-(11)CMTP in tumor tissue was observed. It seems that 5-(11)CMTP will be a potential amino acid tracer for tumors imaging with PET.

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.
