Object To optimize the apheresis procedure of mononuclear cells from bone marrow for different clinical treatments. Methods Bone marrow mononuclear cells were separated from bone marrow using COBE Spectra apheresis system. Cell morphology, cell counts, positive expression of CD34, CD133 and CD271 were detected, and the obtaining percent of total nuclear cells and mononuclear cells were calculated. The relationships between cell-morphology and CD34, CD133 and CD271, were also analyzed. Results 1)The positive expression of CD271 was correlated with monocytes before and after apheresis (P

?AIM:To investigate the correlation between dry eye and different degrees of diabetic retinopathy ( DR ) in type 2 diabetic patients.?METHODS: In the cross-sectional study, 340 patients (340 eyes) with type 2 diabetes were enrolled. Tear film function tests including tear meniscus height, tear film breakup time ( BUT ) , fluorescein staining, Schirmer Ⅰtest were performed followed by surveying questionnaires about dry eye. Retinal status was evaluated by retinal color photography and indirect ophthalmoscopy exam with dilated pupils to evaluate DR and whether companied by macular edema.?RESULTS:The prevalence of dry eye was 49. 41%. The mean duration of diabetes in patients with dry eye was 11.15±7.07a, while 6.92±5.45a without dry eye(P<0.01). Dry eye had the positive correlation to the development of DR. The incidence of dry eye in people with mild nonproliferative diabetic retinopathy ( NPDR ) , moderate NPDR, severe NPDR and proliferative diabetic retinopathy (PDR) was 1. 097 times, 1. 724 times, 2. 86 times and 5. 43 times respectively, compared with people without DR. The occurrence of dry eye in people with macular edema increased by 3. 697 times compared with people without macular edema.?CONCLUSION: Dry eye was more prevalent in people with type 2 diabetes. The incidence of dry eye increased gradually with the occurrence and development of diabetic retinopathy.

Objective To understand the mortality rate and cause of the injury in Hebei province in order to provide scientific theoretical basis for drawing up effective prevention measures.Methods The injury deaths data was collected from 18 surveillance spots in Hebei province during 2004—2005,and the injury was classified with ICD-10 and the corresponding mortality rates were calculated.Results The average injury mortality rate was 54.02/100 000(the age-adjusted rate was 51.62/100 000).It was the 5 th-ranked cause of death.The leading five causes of injury were traffic injury by motor vehicles, traffic injury by non-motor vehicles,suicide,poisoning and fall,which accounted for 23.96%,22.05%,13.10%,11.99%, 5.62%,respectively.The average injury mortality rate in rural(58.48/100 000)was higher than in urban(31.60/100 000)(?~2= 255.82,P

Objective To explore the clinical features and surgical management of aged patients with acute cholecystitis,and try to command the opportunity and procedure of laparoseopic cholecystectomy(LC)better.Meth- ods Clinical data of 52 aged cases with acute cholecystits undergone LC were analyzed retrospectively.Results All of the patients(within 48h of the acute attack)were successfully recovered without serious operative complications. Conclusion Aged acute cholecystitis progressed rapidly and its operative difficulty and risk were higher;only if more attention was paid to perioperative managements and operative time and technical skill were mastered,early LC for the patients was safe and feasible.Therefore.it should be recommended in the great majority of cases except the des- perate patients whose general condition was too poor to operate.

Objective To understand human rhinovirus (HRV) etiology of acute lower respiratory tract infection (ALRTI) in children in Shanghai area and establish a nested reverse transcription- polymerase chain reaction (nested RT-PCR) assay.Methods Three hundred and forty-two naso- pharyngeal secretion (NPS) samples from ALRTI cases who were hospitalized were collected during January 2005—December 2005.Nested RT-PCR techniques were used to detect HRV-specific RNA.The PCR products were sequenced and data of nucleotides were analyzed.The proportion of HRV infection in children with ALRTI,the distribution of gender,age and season,and clinical char- acteristics were also investigated.Results Forty-six (13.5%) of 342 samples were HRV positive detected by nested RT-PCR.The sequences of 15 positive samples shared high homology of 83%- 97% with HRV sequence in GenBank.Within the 15 positive samples,nucleotide homology varied from 64.4% to 98.4%,and the ratio of genetic variation was from 1.6% to 48.3%./00.These 15 ampli- cons attribute to the two branches of HRV cladogram.The sequences of 15 amplieons were highly varied,in which single nucleotide mutation and several nearby nueleotides mutations were found. Ribonucleotide deletion and insertion in the nucleotide sequence was also found.HRV positive sam- ples were detected in 33 boys and 13 girls,respectively.The ratio of infection cases between boys and girls was 2.5:1.Of 46 HRV infected cases,27 (58.7%) were less than 12 months of age and 38 (82.6%) were less than 3 years old.HRV infected ALRTI occured all the year round and peaked from March to May.Of the patients whose NPS samples were HRV positive detected by nested RT-PCR,45 patients were diagnosed with bronchopneumonia and 1 was diagnosed with asthmatic bronchitis.Fever of most patients was moderate.The peripheral blood leukocyte counts in thirty-nine (84.8%) patients were less than 10?10~9/L.Neutrophil percentages in thirty-seven (80.4%) patients were less than 0.50.C-reactive protein of thirty-six (78.3%) patients were less than 8 mg/L. All of these features were the characteristics of viral pneumonia.The complications were not common and conditions of most patients were not severe.All the children were cured.Conclusions This nes- ted RT-PCR technique is highly specific,rapid and convenient for the detection of HRV RNA in NPS of patients with ALRTI and the genome of HRV viruses is highly variable.The incidence of HRV infection predominates in children in Shanghai area.ALRTI of HRV is short of specificity and condi- tions of most patients are not severe and their prognoses are fine.

Objective To investigate the roles of a variety of cytokines including transforming growth factor beta (TGF-β),interleukin-6 (IL-6) and interleukin-2 (IL-2) in the differentiation of CD+4 Tlymphocyte cells.Methods T lymphocyte cells either in human peripheral blood or routine spleen were cultured in vitro under different stimulation conditions.Flow cytometry was used to analyze the percentages of CD+4IL-17+ T-helper 17(Th17) cells,CD+8 IL-17+ T cells,CD+4 CD+25 FOXP+3 T regulatory (Treg) cells among activated T cells.Results Differentiation of Treg cells,Th17 cells and CD+8 IL-17+ T lymphocyte cells was enhanced when murine splenic T cells were cultured with TGF-β.The levels of expression were (7.8±2.2)%,(12.6±3.1)%,(10.1±2.6)% ,respectively.Experimental control group was severally same type of T cells without cytokine treatment.The levels of expression were (4.8±0.6) %,(1.7±0.5) %,(1.0±0.4) %,respectively.There were statistically significant differences among them (q=4.09,8.80,9.61.P<0.05 or P<0.01).Under combination treatment with IL-6 and TGF-β,(17.8±5.3) % Th17 cells and (15.0±4.2)% CDCD+8 IL-17CD+ T cells were induced,whereas the levels of Treg cells whose differentiation were restrained were (4.1±1.2) %.The differences were statistically significant compared with the level of same type of T cells in TGF-β group (q=5.03,5.17,5.04,P<0.01).Moreover,combination treatment with IL-2 and TGF-β decreased percentages of Th17 and CDCD+8 IL-17CD+ T cells and increased percentages of Treg cells in T cell population.There was an opposite effect when anti-IL-2 was apphed.The percentages of Th17 and CD+8 IL-17+ T cells were increased and the percentages of Treg cells were reduced The regulation trend of T lymphocyte cells in human peripheral blood was similar with those in routine spleen.Conclusion Various cytokines are of great importance in the regulation of the balance between Th17 and Treg cell.

Objective To understand the current status of advanced schistosomiasis in Pukou District,Nanjing City,so as to provide the evidence for its appropriate treatment. Method An epidemiological investigation and medical examinations were carried out based on the national standard for the people who either had been already identified as advanced schistosomiasis or were new suspects. Results There were 55 cases of advanced schistosomiasis in Pukou District,2013. Among them,51 cases (92.73%)were splenomegaly type and 4 cases(7.27%)were ascites type. Fifty-three cases(96.36%)were clinically cured,1 case(1.82%)was in the stable condition and 1 case(1.82%)still needed further treatment. In terms of the age,the youngest was 49 years and the oldest was 86 years. The gender distribution was male accounting for 58.18%(32 cases)and female 41.82%(23 cases). Conclusion The condition of patients with advanced schistosomiasis in Pukou District,Nanjing City is complicated. The investigation and treatment to the patients should be conducted regularly.

Objective To understand the characteristics of molecular epidemiology of enterovirus 71(EV71) in children with hand, foot and mouth disease (HFMD) in Shanghai area during the first half year of 2009. Methods Seventy-three throat swabs and 38 stool samples were collected from 95 hospitalized children with clinical diagnosis of HFMD in Children's Hospital of Fudan University during April to May 2009. TaqMan real-time reverse transcription-polymerase chain reaction (RT-PCR) and nest RT-PCR were used to detect EV71 VP1, followed by gene sequencing analysis. Results Six of the 73 throat swabs were EV71 positive with the detection rate of 8.2%. In the 38 stool samples, 24 were EV71 positive with the detection rate of 63.2%. Twenty-eight nested RT-PCR positive samples were sequenced and the genetic analysis showed that 27 were C4 subtype,which were absolute dominant strain and the other one was C2 subtype. The isolated strain from a fatal case was C4 subtype and there was no obvious mutation found in VP1 region. Conclusions EV71 is an important pathogen in HFMD children in Shanghai area during April to May 2009. C4 subtype strains are absolutely dominant, and accompanied by epidemic strains of subtype C2.
