status.Conclusion HPV6 and HPV-16 were the most two popular HPV types in the whole population,while HPV-16 was the most common type in CIN2+ population.HPV-16 seroprevalence increased with severity of cervical intraepithelial neoplasia.

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.

Objective To investigate the expression and correlation of NKG2D and sMICA in lung cancer patients. Methods By collecting 30 lung cancer patients as the test group,and taking 30 healthy volunteers as the contrast group, the expression of NKG2D and sMICA in the two groups were examined separately by FACS and ELISA method. Results The expressions of NKG2D in the two groups were (81.56±8.78) %, (85.63±6.62) %. The lung cancer patients were high remarkable. There was a significant difference between the two groups (P <0.05). The expression of sMICA in the two groups were (354.13 ±80.575) pg/ml,(216.53±48.175) pg/ml. The lung cancer patients were low remarkable. There was a significant difference between the two groups (P <0.01). There was a significant relation between the two groups (r =-0.349, P =0.006). Conclusion The expression of NKG2D and sMICA may provid one of the immune targets for diagnosing that can forecast the immune state and malignant metastasis of the lung cancer patients. The significant relation between NKG2D and sMICA may take on main role in the immune escaping of tumor. It may provide the suitable target of the patients for tumor organisms and immune treatment.

Objective: To investigate the human papillomavirus (HPV) positive rate and its usefulness in predicting CIN2+ in women with atypical squamous cells of undetermined significance (ASC-US) cervical cytology. Methods: A pooled analysis was conducted using published data of hospital classification, HPV positive rate and histopathologic diagnosis in ASC-US population during 2005 to 2017 from 104 studies which enrolled 28 923 ASC-US samples. Results: The overall HPV positive rate was 52.09% (range from 12.06% to 88.68%). The HPV positive rate in 79 tertiary hospitals of 21 244 cases was 52.46%, slightly higher than the 50.87% in 22 second-class hospitals of 6 925 cases. There was no significant difference between specialized hospitals and general hospitals. In addition, the positive rate of HC2 conducted in 66 hospitals with 19 791 cases was 53.13%, which was slightly higher than 51.10% of reverse hybridization from 24 hospitals with 6 338 cases. In 73 studies of 18 163 cases with histological diagnosis, the sensitivity of HPV for detecting CIN2+ was 90.16% (95%CI: 88.91% to 91.28%), specificity was 53.08% (95%CI: 53.02% to 54.57%), positive predictive value was 23.24% and negative predictive value was 97.24%. Conclusion HPV detection is clinically validated for ASC-US triage, but there is a wide variation of HPV positive rate in population of cervical cytological diagnosis as ASC-US in China, suggesting different diagnostic level between regions and hospitals and further improvement is needed.

AIMTo examine the impact and prognostic significance of alpha-tocopherol associated protein (TAP) expression in a series of prostate cancer patients.

METHODSTissues from 87 patients underwent radical prostatectomy were examined for TAP expression by immunohistochemistry. The relationships of the staining results, the clinic pathological characteristics and the recurrence times were analyzed.

RESULTSCompared with the adjacent areas of normal and benign glands, immunoreactivity of TAP was reduced in areas of prostate cancer. A lower TAP-positive cell number per mm(2) of the largest cancer area (defined as TAP-PN) was associated with higher clinical stage (r = -0.248, P = 0.0322). Inverse associations were found among the TAP-PN and positive lymph nodes (r = -0.231, P = 0.0325), preoperative prostate-specific antigen (PSA) levels (r = -0.423, P = 0.0043), tumor size (r= -0.315, P= 0.0210) and elevated tumor cell proliferation, which was indicated by the staining of Ki-67 (r = -0.308, P = 0.0026). TAP-PN was a significant predictor of recurrence univariately (P = 0.0006), as well as multivariately, adjusted for known markers including preoperative PSA, clinical stage, Gleason score, surgical margin, extra-prostatic extension, seminal vesicle invasion and lymph node metastasis (P = 0.0012).

CONCLUSIONReduced expression of TAP was associated with the cell proliferation status of prostate cancer, adverse pathological parameters and the increased risk of recurrence.

OBJECTIVETo observe the effects of NBD-peptide pretreatment of the donor dendritic cells in immune tolerance induction in mouse allograft recipients and investigate the mechanisms.

METHODSBALB/c mouse DCs pretreated with NBD-peptide (NBD-Peptide-DC) were injected into the recipient C57BL/6 mice 7 days before transplantation. Cervical heterotopic heart transplantation model was established using the cuff technique and the cardiac allograft survival time was observed. Pathological analysis were performed to examine the graft injection and the responsiveness of the recipient spleen T cell to the donor alloantigen was determined by mixed lymphocyte reaction (MLR). The serum levels of cytokines were determined using ELISA.

RESULTSThe cardiac allograft survival time in the NBD-Peptide-DC-treated group (21.83-/+3.54 days) was significantly longer than that in the Day9-DC group (13.33-/+2.58 days) and PBS-treated group (6.66-/+1.21 days) (P<0.01), with also significantly lower pathological grade for graft rejection (P<0.01). The donor-derived NBD-Peptide-DCs induced alloantigen-specific T-cell hyporesponsiveness. In the NBD-Peptide-DC-treated group, the serum levels of IL-12 and IFN-gamma decreased significantly (P<0.01), but the levels of IL-4 and IL-10 increased significantly (P<0.01).

CONCLUSIONInjection of donor-derived NBD-Peptide-DCs can leads to donor-specific tolerance in the transplant recipients, and the induction of recipient T-cell hyporesponsiveness and polarization of Th2 response may play important roles in immune tolerance to cardiac allografts.
