Conclusion Octreotide combined with glonoin have satisfied curative effect for EGVB patients, and had less untoward effect,it was worth generalizing.

Objective · To detect gingival thickness of the anterior teeth region of Han nationality youths in Shanghai by cone-beam computerized tomography (CBCT), and evaluate its clinical application feasibility and the gingival biotype. Methods · Firstly, gingival thickness in the same site (5 participators, 30 sites) was detected by bone sounding and CBCT respectively, and the data were compared. A total of 30 participators with healthy gingival were recruited to the study and examined by the CBCT, the gingival thickness of selected sites (330 sites) was assessed and compared. All the subjects were examined by the experienced doctors and classified into three groups, thick-type middle-type and thin-type. Gingival thickness range and the proportion of every type were obtained. All data analyses were performed using SPSS 13.0. Results · There was no statistical difference in the thickness of gingival measured by bone sounding and CBCT (P>0.05). The main gingival biotypes of Han nationality youths in Shanghai were thin-type and middle-type. The average gingival thickness of upper central incisors [(1.32±0.15) mm] was larger than those of upper lateral incisors [(1.07±0.16) mm,P=0.000] and upper canines [(1.08±0.18) mm, P=0.000]. Conclusion · CBCT is feasible for detecting gingival thickness. Gingival thickness of the upper central incisors is significantly larger than those of upper lateral incisors and upper canines. The main gingival biotype of Han nationality youths in Shanghai is middle-type, the proportion of thick-type is least.

Objective To investigate the feasibility of the functional pulmonary lobectomy (FPLT) by studying the blood-gas and morphology of the FPLT model. Methods 18 healthy dogs were divided into three groups randomly: Group A (n=6): the target bronchus and lung bubbles were filled with emulsion of iodine oil and pingyangmycin(PYM)and then target bronchus was occluded with polymethylmethacrylate(PMMA).Group B (n=6): the target bronchus was only occluded with PMMA and Group C (n=6): the target pulmonary lobe was resected. Artery blood gas were measured at the time of pre-operation and post-operation immediately and then 1st, 2nd, 3rd and 4th week after operation respectively. Chest radiolography and histology and bacterial culture of tissue of target lung lobe were made after 4 weeks. Results There was a significant difference in artery blood-gas among 3 groups pre-operation compared with post-operation immediately (P0.05) compared with 1st, 2nd, 3rd and 4th week after operation. It showed atelectasis radiologically and fibrosis of target lung lobe histologically and no bacterium grew in target tissue the 4th week after operation. There were 3 cases of lung atelectasises but no pulmonary fibrosis in group B. Conclusion FPLT may be obtained after the target bronchus and lung bubbles were filled with emulsion of iodine oil and PYM and then target bronchus were occluded.FPLT is a minimal invasive, safe and effective procedure and might partially replace the surgical pulmonary lobectomy in future.

Objective To observe the treatment effect of Buyang Huanwu Decoction combined with low molecular weight heparin calcium injection in treating deep venous thrombosis (DVT) in lower limb after cesarean section. Methods Seventy-six cases of DVT after cesarean were randomly divided into 2 groups. Thirty-six cases of control group were injected low molecular weight heparin calcium subcutaneously 100 AXaIU/kg twice daily, and forty cases of treatment group were treated with Buyang Huanwu Decoction additionally. After analysing the clinical symptoms and sign before and after treatment, HBV, LBV, PV, FIB, PLT, APTT, TT, PT and indexes of impedance plethysmography, CDFI were observed to evaluate the efficacy. Results After treatment, the total effective rate of treatment group was 97.5%(39/40), and the control group was 77.8%(28/36), the difference was statistically significant (P<0.05). The differences of hemorheological indexes (HBV, LBV, PV, FIB) and impedance plethysmography indexes between before and after treatment in treatment group were statistically significant (P<0.05), while the differences of blood coagulation indexes (APTT, TT, PT) were not significant (P>0.05). No adverse reaction was found during treatment. Conclusion The treatment of DVT after cesarean section with Buyang Huanwu Decoction combined with low molecular weight heparin calcium injection is safe and effective.

Objective To study the correlation of mitochondrial DNA mutation of spermatozoa and change of mitochondria-ultrastructure with male infertility. Methods The techniques of PCR and DNA sequence analysis were used to detect MTCYB and MTATP-6 fragments of 76 samples of semen with poor motility from infertile male.Of these samples five were identified with mitochondrial DNA deletion and transmission electron microscopic observations were made. Results Under the electron microscopic observations the 5 samples were all seen with abnormal volume of mitochondria in most spermatozoa tails either small or big, disorderly located and asymmetrically distributed;the axonemal structures of sperm wrapped in layers of mitochondria. These samples of sperm were noticeably different in form from those from fertile male. Conclusion Sperm mitochondria-ultrastructure change were observed in samples of sperm mitochondrial DNA mutation.Sperm mitochondrial mutation and its mitochondria-ultrastructure affect the energy supply of sperms during the process of fertilization which may result in male infertility.;

Objective To study the in vitro activity of T cells differentiated from bone marrow CD34+ cells of psoriatic patients with family histories. Methods Bone marrow CD34+ cells were isolated from psoriatic patients with family history and normal persons by immunomagnetic cell selection and induced to differentiate to T cells in thymic stromal microenvironment in vitro. CD3+ T cells were obtained by CD3+ cell selection system and the proportions of CD4+CD8- and CD4-CD8+ cells were measured by flow cytometry. The proliferation activity of T cells was measured by MTT colorimetry in both spontaneous proliferating group and superantigen (SAg)-stimulated group. And the levels of IL-4, IL-8 and IFN-? were quantified by enzyme-linked immunosorbent assay in culture supernatant. Results Mature CD4+CD8- cells and CD4-CD8+ cells were detected from CD3+ cells, which were derived from bone marrow CD34+ cells. When the psoriatic patients and normal controls were compared, there was no significant difference in the proportion of CD4+CD8- cells or that of CD4-CD8+ cells in CD3+ cells. The proliferation activity of T cells was significantly higher in the psoriatic patients than that in the normal controls. There was no statistical difference of IL-4?IL-8 or IFN-? levels in the supernatant of T cells between the spontaneous group and the normal control. However, the IFN-? and IL-8 levels in the supernatant of T cells were higher in the psoriatic patients than those in the normal controls after the SAg stimulation. Conclusion The abnormal activity of peripheral blood T cells from psoriatic patients with family history may be related to the bone marrow hematopoietic cells.

Objective:To raise awareness of acute myeloid leukemia (AML) combined with lymphoblastic lymphoma (LBL) in children.Methods:The clinical characteristics, diagnostic methods, treatment plans and prognosis of a child with AML combined with LBL who was admitted to the First Affiliated Hospital of Zhengzhou University in April 2016 were retrospectively analyzed, and the relevant literature was reviewed.Results:The patient was an 11-year-old boy with fever, abnormal hemogram and cervical lymph node enlargement as clinical manifestations. A biopsy of the cervical lymph node was performed and the patient was diagnosed as T-lymphoblastic lymphoma (T-LBL). After the bone marrow morphology, immunology, cytogenetics and molecular biology (MICM) classification examination, the diagnosis was AML. The patient met the diagnostic criteria of two diseases at the same time, and thus he was confirmed as AML combined with T-LBL. AML chemotherapy regimens were given, and the patient achieved complete remission and disease-free survived.Conclusions:AML with LBL is extremely rare in children. The diagnosis mainly depends on MICM classification examination of bone marrow and pathological examination of lymph nodes. There is currently no standard treatment scheme, and the prognosis is extremely poor. AML chemotherapy followed by bridging hematopoietic stem cell transplantation is the best treatment option for these patients.

Objective To detect mutations of p53 gene 2-4 exons from peripheral blood and to explore their relevance in HPV16-positive cervical cancer susceptibility and clinical significance. Methods Collected firstly cases from the Third Affiliated Hospital of Kunming Medical University from October 2012 to April 2014, included 167 cases HPV16-postive cervical cancer and 160 cases HPV-negative healthy women. Genomic DNA from the host peripheral venous blood was taken, mutations of p53 gene 2-4 exons were analyzed with software DNAstar after PCR and bidirectional sequencing. Meanwhile,mutations of p53 gene 2-4 exons among different clinicopathological characteristics in HPV16-postive cervical cancer were distinguished. Results (1)Three mutations and an 16-bp insertion/deletion sequences were found in p53 gene exons 2-4, included C/G mutation of single nucleotide polymorphism(SNP)11827 in intron2, A/C mutation of SNP11992 in intron3, C/G mutation in codon 72 (rs1042522) of exon4 and 16-bp(acctggagggctgggg) repeat insertion or deletion in intron3 (rs17878362), while deletion recorded as A1, insertion recorded as A2. No significant differences were found in each point allele and genotype frequency(P＞0.05). (2) Stratified analysis for cervical cancer group resulted with some differences. Compared group of non-squamous carcinoma with squamous carcinoma group, there were obviously decreased in allete A2 [11.8%(4/34) vs 3.5%(10/284); χ2=4.90,P=0.027], genotype A1A2 [4/17 vs 7.0%(10/142); χ2=5.14,P=0.023], and haplotype C-A2 [11.8%(4/34)vs 3.5%(10/284);χ2=4.91,P=0.027]. Compared with poorly differentiated group,allele C of SNP11827 and rs1042522 were obviously decreased in medium high differentiation group [50.8%(61/120)vs 38.8%(62/160);χ2=4.07,P=0.044], while haplotype G-A1 were apparently higher [49.2%(59/120)vs 61.2%(98/160);χ2=4.07,P=0.044], genotype GG of SNP11827 and rs1042522 were obviously decreased in superficial myometrial invasion depth group than that in deep myometrial invasion depth group [46.3%(25/54) vs 21.1%(8/38); χ2=7.06,P=0.029]. No significant differences were found between stage Ⅰ and Ⅱ, pelvic lymph node metastasis or not (all P＞0.05). Conclusions No obvious correlation is found between polymorphisms in exons 2-4 of p53 gene and susceptibility of HPV16-postive cervical cancer. But the patient with allete C and A2, genotype GG and A1A2, haplotype C-A2 and G-A1 may be increase risk of poorly differentiation, deep muscular invasion and bad pathological type. Analysis of p53 gene polymorphism may be provide a basis for the prognosis evaluation and individualized treatment of cervical cancer.

OBJECTIVETo study the expression of EpCAM and E-cadherin in papillary thyroid carcinoma and to analyze its correlation with various clinicopathologic parameters.

METHODSImmunohistochemical study for EpCAM and E-cadherin was carried out in 91 cases of papillary thyroid carcinoma. Twenty-four cases of papillary hyperplasia of thyroid were used as controls.

RESULTSIn all of the 24 cases of papillary hyperplasia, EpCAM was located on the cell membrane, while in the 91 cases of papillary thyroid carcinoma studied, EpCAM was located within the cytoplasm, with 36.3% (33/91) showing nuclear localization as well. In all the papillary hyperplasia cases studied, E-cadherin showed membranous expression. E-cadherin expression was reduced in 84.6% (77/91) of papillary thyroid carcinoma, as compared with the surrounding native thyroid parenchyma. Amongst the 33 cases of papillary thyroid carcinoma which showed nuclear localization of EpCAM, 30 cases also showed reduced E-cadherin expression. There was a positive correlation between nuclear expression of EpCAM and loss of E-cadherin expression (P = 0.000; Spearman correlation coefficient = 0.857). Nuclear expression of EpCAM correlated with follicular variant of papillary thyroid carcinoma and presence of extrathyroidal extension ( P = 0.037 and 0.033, respectively). Loss of E-cadherin expression correlated with age of patients and presence of lymph node metastasis (P = 0.018 and 0.010, respectively).

CONCLUSIONSE-cadherin expression is reduced in papillary thyroid carcinoma, as compared with native thyroid parenchyma and papillary hyperplasia. Papillary thyroid carcinoma shows loss of EpCAM membranous expression and increased cytoplasmic/nuclear accumulation. Detection of these two markers may provide a valuable reference in defining the biologic behaviors of papillary thyroid carcinoma, including extrathyroidal extension and lymph node metastasis.
