Objective To understand the existing deficiency in the work of preventing HIV transmission from mother to child.Methods The diagnostic occasions of 179 HIV positive pregnant women(189 pregnant times)in some counties in Hubei,Shanxi,and Hebei were collected,including measures for prevention.The reasons for the missing prevention for HIV positive pregnant women were analyzed.Results The HIV positive rate in pregnant women in the counties enrolled in this study was 0.26‰.Percentage of HIV pregnant women who were found in antepartum,intrapartum,and postpartum were 66.7%,7.4%,and 25.9% respectively.Some HIV positive pregnant women missed the prevention in all of three periods.In HIV positive pregnant women found antepartum,some rejected prevention.The missing reason for HIV positive pregnant women found intrapartum failed to get ARV drug.HIV positive pregnant women found postpartum missed the prevention.Conclusions There is some progress in the work of preventing HIV transmission from mother to child in China,but some HIV positive pregnant women can not be detected in time,and the percentage of HIV pregnant women who have received comprehensive measures is low.The work of PMTCT therefore needs to be improved.

Objection To investigate the spectrum and survival status of HIV positive cancer in HuBei province, China. Methods HIV positive cancer patients were added up and followed up who had registered in Zhongnan Hospital between January 2004 and June 2009. The prognostic features were determined for HIV patients with cancer. Results The average age of HIV positive and HIV negative group who suffered with malignant neoplasm were 42.5±8.8 years and 55.1±13.7 years respectively (P ＜0.05), mean CD4 counts were (220.9±142.3)/μl and (554.4±174.3)/μl, respectively (P ＜0.05), the types of common cancer were NHL, cervical cancer, liver cancer and lung cancer, colon cancer, breast cancer, respectively. Anticancer and/or ART treatment were the important positive prognostic factors. Additional factors such as age and CD4 count were associated with survival of cancer patients with HIV infection. Conclusion Mean age of HIV positive cancer patients is about 42 years old. NHL, cervical cancer and liver cancer are HIV associated malignant tumor. ART and anticancer can effectively prolong the survival of HIV infected patients with cancer.

Objective To evaluate the prevalence and risk factors of human papillomaviruses (HPV)infection among human immunodeficiency virus(HIV)-positive women.Methods Totally 178HIV-positive and 122 HIV-negative women were enrolled.Structured interviews,peripheral CD4 + T cells counts and cervical specimens were obtained.Polymerase chain reaction(PCR)assay was used to identify HPV types. SPSS 16.0 was used for statistical analysis,and logistic regression was used to identify independent prognostic factors for high-risk HPV infection. Results HPV positive rate,high-risk and multiple HPV infection rates were 38.2% vs.12.3% ,35.4% vs.8.2% ,and 13.5% vs.3.3% in HIVpositive women and HIV-negative women,respectively,and the differences were of statistical significance (x2 =24.77,29.08 and 8.91,P ＜0.05).The common types of high-risk HPV were similar between HIV-positive and HIV-negative women(HPV16,52,58 and 18).CD4 + T count ＜ 350/pL,HIV-positive in husband,and HIV infection through sexual contact were risk factors for high-risk HPV infection in HIV-positive women.Conclusion sThe prevalence of HPV infection in HIV-infected women is high,especially for high-risk HPV infection and multiple infection.High-risk HPV infection usually occurs in HIV-positive women with low immune status,HIV infection through sexual contact and HIV-positive husband.

Objective To investigate the stability of immunophenotyping in the course of relapse or at treatment failure of patients with acute lymphoblastic leukemia(ALL) and that of immunophenotyping of positive minimal residual disease(MRD).Methods From Aug.2000 to Dec.2007,33 children with ALL who relapsed or treated failure were enrolled. These children were detected MRD by flow cytometry. The immunophenotyping of children who relapsed or treated failure were compared with that of initial therapy;the immunophenotyping of MRD relapsed was compared with that of initial therapy.Results 1.In 23 out of 27 cases (85.18%) with B-ALL,changed at least 1 antigen between diagnosis and relapse.Six children with CD45 down-modulation and 2 children with CD45 up-modulation.Two children with CD19 down-modulation and 1 child with CD19 up-modulation.Six children with CD34 down-modulation and 4 children with CD34 up-modulation. Five children with CD10 down-modulation and 7 children with CD10 up-modulation.2.Six children with T-ALL had the same expression in CD45 between relapse and treatment failure. 3.These were 15 children had the least 1 case MRD,25 cases MRD were detected,these was 1 case up-modulation in CD45,1 case down-modulation in CD19,2 cases up-modulation and 8 cases down-modulation in CD34,3 cases up-modulation and 6 cases down-modulation in CD10.Conclusions Immunophenotyping of children with ALL may change at relapse and treatment failure. The frequency of change in B-ALL is higher than that of in T-ALL,but the change can not impact the detection of MRD.

Objective To investigate prevalence HPV infections in cervix among HIV-infected Chinese women.Methods From September 2009 to May 2011,293 women with positive HIV underwent cervical cancer screening as study group matched with 200 women with negative HIV as control group.Questionnaires including demographic information and HIV associated information were collected,Pap smear and 23 subtype of HPV were performed in those women.The women with positive HPV were followed up per 6 months,and the period of following up were more than 12 months.Binary logistic analysis was used for high risk factors of HPV persistent infection.Results Prevalent HPV infection was 44.4％ (130/293) in study group and 20.0％ (40/200) in control group,respectively,which reached statistical difference( P ＜0.05).The most common genotype of HPV was HPV 16,which prevalence was 13.7％ (40/293)in study group and 7.0％ (14/200) in control group.The other HPV subtype prevalence was HPV-58,HPV-52,HPV- 43 and HPV-18,which was 9.2％ (27/293),8.2％ (24/293),8.2％ (24/293),6.8％ (20/293) in study group and 3.0％ (6/200),2.5％ (5/200),1.5％ (3/200),2.5％ (5/200) in control group.At time point of 12 months following up,the persistent prevalence of HPV was 47.5％ (48/101) in study group and 21.1％ (8/38) in control group,which reached statistical difference (P＜0.05).Multiple HPV infections ( OR =6.4,95 ％ CI:1.6 - 25.6),abnormal cytology ( OR =18.1,95 ％ CI:4.5 - 76.9 ) and lower CD4 T cell count (compaed with CD4 ＞3.5 × 108/L,if 2.0 × 108 ≤CD4 ≤3.5 × 108,OR =8.1,95％ CI:1.3 -56.3 ; if CD ＜ 2.0 × 108/L,OR =9.1,95％ CI:1.8 - 46.9 ) were independently associated with HPV persistence among HIV-positive subjects.Conclusions Prevalence and persistence of HPV infections were more common among HIV-positive Chinese women than those in HIV-negative Chinese women.Improving immune function,decreasing multiple HPV infections,treating abnormal cervical cytology could decrease prevalence of HPV infection.

Objective To compare the epidemiological characteristics of patients acquiring human immunodeficiency virus (HIV) infection through sexual contact or blood transfusion. Methods A total of 679 HIV/AIDS patients were recruited. The informed consents were obtained from all participants. CD4+T lymphocyte count, anti-syphilis and HIV-1 subtype of recruited cases were tested, and anti-HIV of their spouses was tested.Human papillomavirus (HPV) genotyping was performed in female patients. The data were analyzed by t test and chi square test. ResultsThere were 348 cases in heterosexual transmission group (STG) and 331 in blood transfusion group (BTG). HIV-1 genotyping was performed in 120 STG cases and 90％ (108/120) were mixed genotypes; HIV1 genotypes in 107 BTG cases were all subtype B'. Curable sexual transmitted diseases (STDs) in STG and BTG were identified in 293 and 156 cases, respectively. The incidence of cSTDs were 34.1％ (100/293) in STG and 5.8％ (9/156) in BTG (x2 =44. 541, P＜0.01). Forty-three females in STG and 138 females in BTG were tested for HPV, and the HPV infection rates ware 67.4％ (29/43) and 26.8％ (37/138), respectively (x2 =23. 361, P＜0.01). Among 348 cases in STG and 331 cases in BTG, the rate of HIV transmission between couples was 48.9％ (170/348) and 23.3％ (77/331),respectively (x2 =47. 991, P＜0. 05). ConclusionsThe diagnosis of HIV infection acquired through sexual contact is usually late, which results in a relatively high risk for viral transmission. Furthermore, the co-infection of HIV and HPV or other sex transmission disease is common.

OBJECTIVETo evaluate the value of transbronchial needle aspiration (TBNA) combined with transesophageal endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) in the diagnosis of mediastinal and pulmonary hilar lesions as well as in the lymph node staging (N staging) of lung cancer.

METHODS129 patients with mediastinal and pulmonary hilar lesions underwent either TBNA or EUS-FNA with cytological needle aspiration. The samples obtained from TBNA or EUS-FNA were examined by both cytologiy and histopathology.

RESULTSOf the 129 patients, 59 underwent TBNA and 70 EUS-FNA. The diagnostic rate were 84.7% (50/59) by TBNA and 94.3% (66/70) by EUS-FNA, resepectively. The diagnosis of 116 (89.9%) patients were confirmed by either TBNA or EUS-FNA. The pathological and cytological diagnostic rates were 92.2% (107/116) and 88.0% (102/116), resepectively. The diagnostic rate was elevated by 8.4% (9/107) through pathological examination. The histological classification rates by cytological and pathological examination were 73.8% (76/116) and 89.3% (92/103), respectively. The diagnostic rate of histological classification was elevated by 35.5% (27/76) through pathological examination.

CONCLUSIONThe combination of TBNA and EUS-FNA can improve the diagnostic rate for wider mediastinal and pulmlonary hilar lesions. Pathological examination of the samples obtained from the TBNA and EUS-FNA can elevate not only the rate of diagnosis but also the rate of histological classification.

OBJECTIVETo analyze the pathological type and clinical features of patients with lymphoma cell leukemia (LML).

METHODSAccording to the 2008 WHO classification of tumors of hematopoietic and lymphoid tissue, the pathological type and clinical features of 127 LML cases were analyzed retrospectively.

RESULTSThere were 15 kinds of NHL developed LML. The incidence in frequent order of them was B-lymphoblastic lymphoma, CLL/small lymphocytic lymphoma (SLL) and T-lymphoblastic lymphoma. The LML of T and B cell subtypes were 45 and 74, respectively. There was a significant difference in overall survival between T-LML and B-LML (P < 0.01). Eighty one patients presented LML at the same time of the NHL diagnosis and 46 during the course (1 - 88 months) of disease. Primary nodal and extranodal NHLs developed LML were 96 and 31 cases, respectively. The clinical manifestations of LBL and SLL patients differed from that of ALL and CLL patients.

CONCLUSIONLML is not a rare manifestation of NHL. Pathological types of NHL developed LML are 15 kinds in our patients. The clinical features of LML patients are somewhat special, especially for primary extranodal LML patients.

OBJECTIVETo explore biological exposure markers, we investigated the chromium content in peripheral erythrocytes from occupational population with broad ranges of soluble chromate exposure, as the candidate biomarker may provide the scientific evidence for health risk assessment in occupational chromate-exposed population.

METHODSA cross-sectional study was conducted in chromate exposed workers employed at a chromate factory in a district of Jinan city, Shandong Province. The studied population contained 114 workers from different processes of the chromate plants, which included 74 males and 40 females, with an age range from 25 to 52 years old, averaging at (35.83 +/- 6.14) years old; the length of service was ranging from 1 year to 37 years, an average of (14.20 +/- 6.77) years. In addition, 30 farmers in the countryside one hundred kilometers away from the factory, without exposure to chromate matched with exposed subjects by age, gender and smoking status were identified as a control group, which included 22 men and 8 women, with age ranging from 25 years old to 47 years old, having an average age of (36.13 +/- 6.17) years old. Personal information on age, chromate exposure, medical history, smoking habit and alcohol consumption was obtained at an interview. The air concentration of personal exposure was determined by individual sampling for 8 hours per day as shift work, and chromium was assayed by atomic absorption spectrometry. The chromium content in the erythrocytes from peripheral blood was determined by graphite furnace atomic absorption spectrometry. The potential plasma reduction capacity was determined by dibenzene anthracoamid dihydrazide spectrophotometry. The content of total vitamin C and reductive ascorbic acid were determined by 2, 4-dinitrobenzene hydrazine. The data were analyzed by SPSS10.0 software for statistical significance.

RESULTS(1) The results showed that the chromium levels in erythrocytes in the exposed group [(15.79 +/- 31.01) microg/L] were significantly higher than those in the control group [(3.21 +/- 2.20) microg/L] (P < 0.01). (2) There existed a dose-response relationship between the personal airborne chromate concentration and the chromium content in erythrocytes. As airborne chromate concentration lowered to 106.00 microg/m(3), the chromium content in erythrocytes increased, depending on the air concentration of chromate. (3) Correlation analysis showed that there was a significant positive correlation between airborne chromate concentration and the chromium content in erythrocytes (P < 0.01). (4) In multiple regression analysis, it was found that the potential plasma reduction capacity and reductive ascorbic acid may be a good indicator for oxidative stress produced by chromate exposure and be used to evaluate the effects on intracellular uptake of chromium (VI).

CONCLUSIONOur findings suggested that the chromium content in erythrocytes should be used as an effective exposed biomarker in the risk assessment for occupational chromate-exposure.
