Objective To explore clinical characteristics and treatment of the thrombotic microangiopathy (TMA) induced by malignant hypertension, and provide a better understanding of the disease. Methods The clinical manifestations, laboratory examinations, therapeutic methods and prognosis of 15 TMA patients induced by malignant hypertension were analyzed retrospectively. Results The clinical manifestations were characterized by microangiopathic hemolytic anemia, thrombocytopenia and kidney injury. None of the patients required plasma exchange therapy. After antihypertensive treatment, all of 15 patients were discharged with improved clinical condition, remoglobin levels and platelet count. Conclusions The TMA induced by malignant hypertension is different from the classic TMA. Improving the understanding of TMA induced by malignant hypertension will contribute to early diagnosis and targeted treatment.

Objective To investigate the relationship between the insertion/deletion(I/D) polymorphism of the angiotensin convcer-(ting) enzyme(ACE) gene and congenital heart disease(CHD) and to quest the predisposing gene of congenital heart disease by analyzing the polymorphism of the ACE gene in patients with CHD.Methods Sixty-eight patients with CHD were served as observing group,sixty-four patients without CHD as control group.We drew DNA of leukocyte from blood by the method of saturation phenol and chloroform and we amplified the ACE gene using the DNA polymerase chain reaction technique.The amplification products were employed electrohoresis in 2% sepharose.the polymorphism of the angiotensin converting enzyme gene was analyzed under ultraviolet lump.Results In the obser-(ving) group,the genotype distribution frequency of the ACE was II in 12(17.65%),DD in 32(47.06%) and ID in 24(35.29%),and in the control group,it was II in 20(31.25%),DD in 10(15.63%) and ID in 34(53.12%).Conclusions The study result clarifies that CHD has close correlation to the polymorphism of the angiotensin converting enzyme gene.The relative risk of DD genotype is higher than that of the others,and DD genotype possibly is the predisposing genotype of CHD D allele perhaps is the susceptibility gene of CHD.

Objective To analyze the clinical and molecular epidemiology in children with measles in Shanghai and identify the clinical characteristics and the prevalent genotype of measles virus.Methods The clinical features of measles-such as ages of onset,crowds and epidemiological data were retrospectively analyzed in 39 children with measles from Nov.2005 to Jun.2006 in Children′s Hospital Affiliated to Fudan University.Results of blood routine test,liver function test and chest X-ray were also included.Sputum examinations were carried out on the ones who had bronchitis or bronchopneumonia.Throat swab specimen within 3 days of the onset of rashes were collected and were sent to Center for Disease Control and Prevention (CDC) of Shanghai to isolate measles virus,then the genotypes of the isolated viruses were determined subsequently in CDC of China.Results Twenty-nine cases out of the 39 children were from foreign provinces (74.36%).Among of them,24 cases were younger than (or as young as) 9 months old.Among the 39 cases,35 children had never been inoculated with measles vaccine,and to speak of the ones who were younger than 8 months,the ratio was 57.14%.Five cases out of the 39 children had contacted with measles sufferers.Clinical manifestation were fever,rashes,Koplik spots and catarrh.Twenty-three cases were co-infected with respiratory system and only 8 cases were identified as infection with bacteria or other viruses.The genotype of all analyzed measles viruses belongs to H1a.Conclusions There are also some changes in age groups and endemic distribution,such as younger age and more immigrants except for the typical clinical manifestation of fever,rashes,Koplik spots and catarrh.The predominant genotype is still H1a as in most parts of China.There is no evidence to demonstrate any relationship between the raised morbidity of measles and the genovariation of measles virus.

0.05). Conclusions The distribution of the RMSh was widely ranged among hyperopic children,and some children expressed higher value of RMSh. As the pupil diameter got larger,the RMS value of HOA significantly increased. Vertical coma was more frequent dominating type of HOA among hyperopic children. (Ophthalmol CHN ,2006,15: 187-190)

Objective To explore surgical methods of removing polyacrylamide hydrogel (PAHG) and the right time of repairing the deformity of breast after removing PAHG.Methods We operated with endoscopy to remove PAHG through the lower mammary areolar incision.According to injection influence,we made the dicision whether to put the silicon gel prosthesis (hereafter referred to as prosthesis) simultaneously,and to fix the porsthesis,and to rebuild the imframammary fold of breast using biological repair membrane (hereafter referred to as membrane).Results In all 46 patients,39 patients' injection and their envelope were removed entirely.7 patients left part of the envelope because of its thin and wide characters.14 of them accepted prosthesis augmentation mammaplasty simultaneously and 5 of these accepted membrane repair.4 patients received prosthesis augmentation in stage Ⅱ.All patients' incision were primary healing.The incision scars were not obvious.1 patient with breast cancer suffered breast excision; 1 patient who received prosthesis and membrane simultaneously appeared prosthesis displacement after 3 months and fixed again.1 patient who received membrane appeared hydrops in residual cavity,and the membrane was removed finally.Conclusions This method with endoscopy through mammary areolae is necessary for cleaning PAHG entirely.We can use prosthesis to repair the deformity of breast after removing PAHG,and if necessary use membrane to fix the implant and rebuild the inframammary fold of the breast.

Objective To explore the effects of 1α,25-dihydroxyvitamin D3 [1,25(OH)2D3] on memory CD4+T cells of focal proliferative IgA nephropathy (IgAN)patients.Methods (1) Total of twenty incipient focal proliferative IgAN patients (Lee classification:Ⅲ level) were chosen as IgAN group and 20 healthy volunteers were chosen as healthy control group.The level of serum 1,25(OH)2D3 was measured by radioimmunoassay (RIA).Peripheral blood mononuclear cells (PBMCs) were separated by the method of Ficoll density gradient centrifugation and were stimulated with anti-CD3/anti-CD28 in the absence or presence of various concentrations of 1,25(OH)2D3,Dexamethasone(DEX) and 1,25(OH)2D3and DEX combined.PBMCs were cultured for 72 hours and the levels of IFN-γ,IL-4,IL-17A,Foxp3 were measured by flow cytometry(FCM),standing for the levels of Th1,Th2,Th17,Treg.(2) IgAN group was divided into two subgroups (proteinuria ＜ 1 g/24 h subgroup,proteinuria≥ 1 g/24 h subgroup),then the serum levels of 1,25(OH)2D3,IFN-γ,IL-4,IL-17A,Foxp3 were compared.Results Compared with healthy control group,serum 1,25(OH)2D3 level of IgAN group was significantly lower (P ＜ 0.05).Serum 1,25(OH)2D3 level in proteinuria≥ 1 g/24 h subgroup was significantly lower than proteinuria ＜ 1 g/24 h subgroup and healthy control group (P ＜ 0.05).The level in proteinuria ＜ 1 g/24 h subgroup was lower than healthy control group,but the difference was not statistically significant (P ＞ 0.05).(2) The levels of IFN-γ and IL-17A and the ratios of IFN-γ/IL-4,IL-17A/Foxp3 in IgAN group increased significantly compared with healthy control group (all P ＜ 0.05),and the level of Foxp3 decreased significantly (P ＜ 0.05).The level of IL-4 also increased,but the difference was not statistically significant (P ＞ 0.05).The levels of IFN-γand IL-17A and the ratio of IL-17A/Foxp3 in proteinuria≥ 1 g/24 h subgroup increased significantly,and the level of Foxp3 decreased significantly,compared with urinary protein ＜ 1 g/24 h subgroup and healthy control group (P ＜ 0.05).The ratio of IFN-γ/IL-4 in proteinuria≥1 g/24 h subgroup and proteinuria ＜ 1 g/24 h subgroup all increased,compared with healthy control group,and the ratio in proteinuria≥ 1 g/24 h subgroup increased significantly (P ＜ 0.05).There was no significant difference in the level of IL-4 among all groups.(3) After treatment with 1,25(OH)2D3,the levels of IFN-γ and IL-17A and the ratios of IFN-γ/IL-4 and IL-17A/Foxp3 decreased significantly,and the level of Foxp3 increased significantly (P ＜ 0.05),and these effects were more obvious as the increase of the drug concentration.The level of IL-4 did not change significantly.The combination of 1,25(OH)2D3 and DEX had a synergistic inhibition on the production of IFN-γ,IL-4,IL-17A,and the ratios of IFN-γ/IL-4 and IL-17A/Foxp3,and had a synergistic promotion on the production of Foxp3.Conclusions There is a certain extent of vitamin D deficiency in focal proliferative IgAN patients,which may be associated with the severity of proteinuria.The disorder of immunomodulatory effects of memory CD4+ T cell might exist in the patients of focal proliferative IgAN.1α,25-dihydroxyvitamin D3 might have beneficial effects on the immunoregulation of memory CD4+T cells of focal proliferative IgAN patients.
