Objective To study the clinicopathologic features,effective therapeutic regimen and prognosis of human immunodeficiency virus (HIV) infection with acute promyelocytic leukemia (APL) and chronic myeloid leukemia (CML).Methods Two cases of HIV infection concurrent with leukemia,one with APL,one with CML,were studied and relevant literatures were reviewed.Results Case 1 was HIV infection concurrent with APL,ATO was used to induce remission,in the eight day of therapy,the patient died of brain disorder.Case 2 was HIV infection concurrent with CML,hydroxycarbamide and interferon were used to induce remission,three month later,state of an illness progressed to acute phase,after combination chemotherapy,concurrent with lung multiple infection (fungus and pneumocystis carinii),at last,the patient died of respiratory failure.Conclusion HIV infection concurrent with acute and chronic leukemia has poor therapeutic effect,and is easy to infect seriously.

Objective To study change of the declarative memory in patients with the calcification of the pallidum.Method The Chinese version of Wechsler Memory Scale(WMS-RC)test and dmwing forgetting curve were applied in 30 patients and 30 normal controls.Results There was no differences in the WMS-CR test's scores between the two groups.The patients had poorly memory preservation rate at the delays of 2 hours((64.10±0.87)%Vs(44.83±1.57)%,P<0.01),despite normal memory preservation rate over 30 mins and the similar slope after the delays of l day in the forgetting curve.There were negative correlations between the size of calcification and the memory preservation rate at the delays of 2 hours and 9 hours(r=-0.743,r=-0.483.P<0.01).Conclusion The results may reflect the effect of the pallidum on"slower confiolidation"declamtive memory process which aroused by a consequence of the repeated firing of hippocampal-neocortieal connections while the patients have normal memory encoding and retrieval.

Objective To investigate the polymorphism of human cytomegalovius UL143 gene of low passage clinical isolates in Guangzhou,China.Method PCR was performed to amplify the entire HCMV ULl43 gene region of 3 clinical isolates,which had been proven by multiplex PCR.The amplification products were cloned into pMD18-T-Vector and subjected to sequencing.The result of DNA sequences were analyzed together with the one of published homologous sequences in GenBank from 14 clinical isolates.Result There were several stop codons in UL143 gene due to a base deletion in open reading frame (ORF) of D3 isolate,which could lead to produce non-functional protein.UL143 ORF of Toledo isolate consisted of 279 nueleotides,encoding a protein with 92 amino acids.UL143 ORFs of other isolates consisted of 252 nueleotides,encoding a protein with 83 amino acids.The DNA sequences were quite conserved and all the variations were base substitution.The amino acid sequences of different isolates were highly conserved.with variation of 1.2%-2.4%.There were no additional or deleted sites of post translational modification of UL143 protein in all clinical isolates except Toledo isolate.There were some differences in the secondary structure among different isolates.The isoelectric point of UL143 protein of all clinical isolates except Toledo isolate was 8.75.Conclusion All DNA and deduced amino acid sequences of UL143 gene shared great similarity among HCMV clinical strains regardless of their polymorphism.

Objective To investigate Chinese patients' preferences for different types of incisions for breast augmentation surgeries and to evaluate the impacts of preoperative education on patients' choices.Methods The 403 patients who underwent implantation surgeries during May 2012 to Dec.2016 were included in the survey.These patients were investigated with questionnaires before and after receiving preoperative education in order to ascertain their preferences and concerns based on comprehensive understanding of different types of incisions.Results After receiving the preoperative education on incisions,158 (39.21％) patients changed their initial choices.The number of patients who chose axillary or periareolar approaches decreased to 205 (50.87％) and 31 (7.69％) respectively,while the number of patients who chose IMF incisions increased to 167 (41.44 ％).The majority of patients who chose the axillary of periareola incisions cited easily-hidden scars as their primary selection criterion (81.95 ％ and 93.55 ％,respectively).However,the patients who opted for IMF incisions primarily concerned about the lower capsular contracture rate (31.74 ％),less tissue trauma (22.75 ％)and lower possibility of injury to the breast parenchyma (21.56 ％).Conclusions The preoperative education materials help the Chinese patients fully understand the characteristics of different types of incision locations and make proper decisions.
