HLA (human leukocyte antigen) is critical molecule relevant to immunoresponse, which is always involved in antigen presentation and determining killing activity of immune cells against tumor. The abnormal expression of HLA in lung cancer is believed to be a common phenomena of tumor biology. It has been demonstrated that HLA expression varies in various types of lung cancer, even in differential stages of one type of lung cancer. HLA expression is highly associated with genre, progression and prognosis of lung cancer. The thorough investigations of the relationship between HLA and lung cancer and of mechanism of HLA abnormality will provide useful information for studying of development of lung cancer and tumor immunotherapy.

The patient 1 was a 9-year-old boy of Hui nationality who presented with recurrent erythema over the face and auricles for 8 years.Telangiectasis and erythema developed on both cheeks 7 months after birth,which gradually spread to the auricles,forearms and both legs with a mild ichthyosiform appearance.At 5 years of age blisters and erosions appeared on the lips,which occurred and were aggravated after exposure to strong sunlight during summer and spontaneously subsided or disappeared in winter.The patient 2,a 3-year-old boy who was the younger brother of the patient 1,presented with recurrent erythema for 2 years.At 1 year of age,erythema began to appear on both cheeks and gradually spread to the buccal region,with mild pruritus and scaling.Meanwhile,the skin of both legs was dry and scaling and gave an ichthyosifonn appearance.The lesions usually appeared in early summer and gradually subsided in winter.No abnormality was found by systemic,laboratory,pathological or other auxiliary examination.Chromosomal abnormality was undetected.Body height was normal.The parents of the two siblings were first cousins.Both children were diagnosed with Bloom's syndrome.

Objective To investigate the clinical feature and prevalence of chronic actinic dermatitis in a four-generation family with both monovular twins affected by chronic actinic dermatitis.Methods The clinical and laboratory findings from monovular twins simultaneously affected by chronic actinic dermatitis and their four-family members were analyzed.Results There were 76 members in the four-generation family,with 22 members (including 14 males and 8 females) diagnosed with chronic actinic dermatitis.No positive results were found from laboratory examinations or environmental survey.Conclusion Chronic actinic dermatitis was inherited in an autosomal mode in this family.

Objective To define the stages of medical rescue after earthquake or tsunami disaster and their significance.Method Three stages of medical rescue were defined according to the clinical features of diseases in 3-37 days after earthquake or tsunami in Pakistan and Indonesia.The classification of diseases was based on the criteria of disaster medical rescue set by World Health Organization.Five diseases including injuries/wounds,acute upper respiratory tract infection,acute hemorrhagic enterocolitis,acute enterecolitis and other diseases of internal medicine except epidemic or suspected epidemic diseases were employed to define the stages of disaster medical rescue.Results Injuries/wounds mainly occurred in 6 days after disaster.The incidences were 61.45% to 79.52% and 61.48% to 72.35% in Pakistan and Indonesia,respectively.The incidence of acute upper respiratory tract infection reached to a considerably high rate one week after disaster.Other diseases usually appeared one week later with incidence of 33.93% to 71.11% and 31.50% to 52.11% in Pakistan and Indonesia,respectively.The rate of acute hemorrhagic enterocolitis was 2%o in Indonesia whereas 35‰of acute enterocolitis was found in Pakistan.Conclusion Three stages of disaster medical rescue could be well defined.(1)Early or critical stage(in 6 days after disaster):Treatment of injuries/wound and resuscitation was the primary step to deal with.(2)Intermediate of subaeute stage(7-30days following disaster):The incidences of various kinds of diseases increased and more medical resources were needed in order to treat the upper respiratory tract infection and to lower the disable rate,and to prevent the prevalence of epidemic diseases.(3)Later or recovery stage(1-3months after disaster):The general condition of victims became even better than that of those affected by commonly occurred local diseases,and during this period,there were shortages of medical facilities and medical personnel.Therefore,supplement of medical resources was required.The well defined stages of medical rescue have an important significance for medical rescue teams to treat victims and prevent epidemic diseases more efficiently and timely,and also provide a guidance of scientific basis for the logistics officers of local government as well as our government to make a proper and reasonable distribution of medical resources,and dispatch and arrangement of medical rescue teams.This guidance also helps to make victims re- reliant.

Objective To analyze the sensitivity of clinical isolates of Candida albicans to flucona- zole,to detect mutations in their ERG11 genes,and to investigate the correlation between ERG11 gene mutation and resistance to fluconazole.Methods Candida albicans was identified from clinical isolates of Candida spp..The sensitivity to fluconazole was detected in vitro by microdilution-basesd method and Rosco tablets method.Three pairs of primers were designed to amplify three fragments of ERG11 gene(483 bps, from 295 bp to777 bp;482bps,from 723 bp to 1204 bp;489 bps,from 1179 bp to 1667 bp)after the extracting of genomic DNA.PCR products were sequenced.Results Eighty clinical isolates of Candida spp.were collected,which included 52 isolates of Candida albicans,all of which were sensitive to flucona- zole.Nineteen mutations were detected in ERG11 gene of 5 fluconazole-sensitive clinical isolates.Of the 19 mutations,14 were samesense mutations,and the remaing 5 missense mutations(T495A,A530C, G640A,A945C and G1609A),resulting in amino acid substitution D116E,K128T,E165K,E266D and V488I,respectively in lanosterol 14 alpha-demethylase.E165K was a novel mutation.Conclusions The clinical isolates of Candida albicans were highly sensitive to fluconazole;E165K and V488I might not lead to the resistance of Candida albicans to fluconazole.
