Objective To report 6 cases of hydroa vacciniforme-like cutaneous lymphoma,and to inves- tigate the relationship between this disorder and Epstein-Barr virus(EBV)infection.Methods Pathological and immunohistochemical examinations were performed in the biopsy specimens obtained from all 6 patients. Skin lesions were subjected to EBV encoded RNA(EBER)detection by in situ hybridization.Serological assay and quantification of EBV DNA were performed.Results All the 6 patients had recurrent papules, papulovesicles,necrosis and variola-like scar with chronic intermittent fever;four of the patients also presented with edema of the face,hands and feet.Pathologically,there were multilocular vesicles in the epidermis,and large numbers of infiltrating lymphocytes through the dermis.The cells were atypical with mitotic figures. Immunohistochemical staining of the lesions of 4 patients showed large quantities of cells expressing CD56, scattered cells expressing CD3 and CD45RO,and cells expressing grazyme B and T cell intracellular antigen-1 (TIA-1);a diagnosis of hydroa vacciniforme-like cutaneous NK/T lymphoma was made in these 4 cases. In the lesions of another 2 patients,the cells expressing CD3 and CD45RO,but not CD56,were observed; the diagnosis of hydroa vacciniforme-like cutaneous T-cell lymphoma was made in them.EBER was detected in the tumor cells of all the 6 patients.The IgG titers of anti-Epstein-Barr viral capsid antigen increased in all patients(1:5120 in 2 cases,1:2560 in 2 cases,1:1280 in 2 cases).The copies of EBV DNA were increased in the peripheral blood of both the two detected cases.A chronic active EBV infection was confirmed in all patients.Conclusions Hydroa vacciniforme-like cutaneous lymphoma is clinically characterized by edema of face,hands and feet,vesicular eruptions and variola like scars;histologically,it is characterized by infiltrates of atypical cells consistent with lymphoma,and necrosis in the center of vessels.NK/T is the primary immunophenotype of this disease.There is a close association between chronic active EBV infection and hydroa vacciniforme-like cutaneous lymphoma.

OBJECTIVEThis study explored the dynamic expression of the E3 ubiquitin-protein ligase gene, Arkadia, in response to carbon tetrachloride (CCl4)-induced liver fibrosis in a mouse model and investigated the differential expression that occurs following treatment with the anti-fibrotic bone morphogenetic protein-7 (BMP-7).

METHODSThirty healthy male imprinting control region (ICR) mice were randomly assigned to three groups: normal (control; n = 6), CCl4-induced model group (model; n = 18), and CCl4-induced model with BMP-7 treatment group (treatment; n = 6). The model group was further divided into three subgroups (n = 6 each) for analysis at 4, 8 and 12 weeks after fibrosis induction. Liver fibrosis was induced by hypodermic injections of 60% CCl4 /peanut oil (5 mL/kg) to the hind legs of mice two-times per week in alternating legs for a period of 12 weeks. At week 9, the treatment group of CCl4-induced mice were given an intraperitoneal injection of BMP-7 (300 pg/g) simultaneously with that day's hypodermic injection of 60% CCl4 /peanut oil, and then every other day for a period of four weeks. The pathological changes in liver tissues were observed after staining with hematoxylin-eosin (HE) and Masson's trichrome. Messenger RNA (mRNA) and protein expression of Arkadia in liver were evaluated using reverse transcription-polymerase chain reaction and immunohistochemistry and Western blotting, respectively.

RESULTSMouse models of liver fibrosis were successfully established by CCl4 exposure. Arkadia, Smad7 and TGF-beta1 mRNA levels were up-regulated in the model group in a time-dependent manner (vs. control group), and BMP-7 treatment led to significant down-regulation of the CCl4-induced expression of the three genes (vs. control group: F = 812.80, 451.46, and 998.96, respectively; P less than 0.01). At week 12, the mRNA levels of Arkadia, Smad7, and TGF-b1 were significantly lower in the BMP-7 treatment group than in the model group (t = 12.108, 18.737, and 16.364, respectively; P less than 0.01). Arkadia, Smad7, and TGF-b1 protein staining was weak in the portal area of control liver tissue. In contrast, the model group showed significantly stronger staining for all three proteins in the portal area and in the cytoplasm of liver cells. The staining of Arkadia, Smad7, and TGF-b1 proteins was significantly lower in the treatment group (vs. control group: F = 8.399, 609.690, and 900.561, respectively; P < 0.01). At week 12, the protein levels of Arkadia, Smad7, and TGF-b1 were significantly lower in the treatment group than in the model group (t = 23.438, 11.667, and 42.889, respectively; P < 0.01).

CONCLUSIONArkadia expression gradually increased along with the development of liver fibrosis but was suppressed by treatment with the anti-fibrotic factor, BMP-7.

OBJECTIVETo analyze and evaluate the acceptability of mifepristone compatible with misoprostone versus conventional surgical abortion among women under unwanted early pregnancy, so as to help the unexpected pregnant women to choose the satisfactory abortion, and to provide the evidence for clinicians to make a proper clinical decision.

METHODSSix medical databases were searched, including MEDLINE, EMBASE, Cochrane library, CBMdisc, CNKI and VIP, together with twelve journals hand-searched, and references of included studies additionally searched. Two qualified reviewers reviewed the original articles, evaluating qualities of articles, and extracting data independently. After heterogeneity test, the data was pooled using Revman software if capable, or descriptive analysis was applied.

RESULTSIn total, nine original clinical controlled trials were included, containing 3565 cases. Before abortion, more unwanted pregnant women chose the medical abortion because they believed medical abortion was less painful than surgical abortion (OR = 466.51, 95% CI: 91.37 - 2381.88), but medical abortion was less time-consuming than surgical abortion (OR = 0.02, 95% CI: 0.01 - 0.06). After abortion, satisfaction with medical abortion was similar to that with surgical abortion, with insignificant difference (P = 0.89). However, second choice and recommendation rates of medical abortion were much higher than those of surgical abortion with OR and 95% CI as 2.72, 2.13 - 3.47 and 4.19, 2.16 - 11.16, respectively.

CONCLUSIONSMedical abortion was less painful than surgical abortion and the rate of second choice and recommendation to others were all also higher than those of surgical abortion. However, the process of medical abortion was not as quick as surgical abortion but the satifacation of both methods seemed similar. Therefore, the two artificial abortion methods were not recommended to replace each other at the present time.

OBJECTIVE: To investigate the value of HE4,CA125 and ovarian malignant tumor risk prediction models(ROMA)in the diagnosis of ovarian epithelial malignant tumors.METHODS: The clinical and pathological data of 247 patients with ovarian tumors(EOC 139 cases,BOT 18 cases,and benign ovarian tumor 90 cases)and 39 patients with uterine fibroids in Liaoning Tumor Hospital from September 2016 to August 2017 were retrospectively analyzed. The levels of serum CA125 and HE4 were measured before operation. The ROMA values were calculated and the relationship between CA125,HE4,ROMA values and clinical pathological parameters were analyzed. The diagnostic evaluation index was calculated,the receiver operating characteristic(ROC)curve was drawn,and the AUC value was also calculated.RESULTS: The positive rate of HE4 in the ovarian epithelial malignant tumor group was significantly higher than that in other groups before and after menopause,the difference being statistically significant(P<0.05).The positive rate of CA125 in the group of malignant epithelial tumor of ovary was significantly higher than that in other groups after menopause,the difference being statistically significant(P<0.05),but there was no statistical difference before menopause(P>0.05).There was no significant statistical difference in the positive rate of ROMA before or after menopause(P>0.05).The sensitivity of CA125 was higher than that of HE4 and ROMA. Specificity of HE4 was higher than that of CA125 and ROMA.Correct diagnosis index of ROMA was higher than that of HE4 and CA125.CONCLUSION: For the diagnosis of ovarian malignant epithelial tumors,the combined detection of serum HE4 and CA125 and ROMA model is superior to the individual detection of HE4 and CA125.

PURPOSE: Professional hemodialysis (HD) nursing tends to be task-oriented and lack consideration of the client's viewpoint. This study aims to interpret the process of psychosocial adaptation to dealing with HD in people with end-stage renal disease (ESRD). METHODS: A grounded theory guided this study. Theoretical sampling included 15 people receiving HD at the HD center of a hospital from July to November 2010. Participants received an information sheet in writing, a verbal invitation, and informed consent forms before interviews were conducted. A constant comparative data analysis was analyzed using open, axial and selective coding. The computer software ATLAS.ti assisted data management. Credibility, transferability, dependability, and confirmability ensured the rigor of study process. RESULTS: This study identified "adopting life with hemodialysis", which captures the process of the psychosocial adaptation in people with ESRD as one transformation. Four categories that evolved from "adopting HD life" are (a) slipping into, (b) restricted to a renal world, (c) losing self control, and (d) stuck in an endless process. CONCLUSIONS: The findings of this investigation indicate the multidimensional requirements of people receiving maintenance dialysis, with an emphasis on the deficiency in psychosocial and emotional care. The study's findings contribute to clinical practice by increasing the understanding of the experience of chronic HD treatment from the recipient's viewpoint. The better our understanding, the better the care provided will meet the needs of the people receiving HD.

OBJECTIVETo investigate the correlation of Epstein-Barr virus (EBV) infection and childhood lymphoma.

METHODSParaffin-embedded specimens of lymphoma collected between 1996 and 2005, including 36 Hodgkin lymphomas (HL) and 51 non-Hodgkin lymphomas (NHL), were included in this study. Paraffin-embedded specimens of reactive hyperplasia of lymph nodes (RL) collected during the same period were used as controls. Immunohistochemical (IHC) assay was used to detect EBV-LMP1 and in situ hybridization (ISH) to detect EBV-EBERs.

RESULTSEBV was detected in 72.2% (26/36) of the Hodgkin lymphomas, 15.7% (8/51) of the non-Hodgkin lymphomas and 33.3% (15/45) of the reactive hyperplasia of lymph nodes. There was a significant difference among Hodgkin lymphoma, non-Hodgkin lymphoma and RL (P = 0. 000).

CONCLUSIONChildhood Hodgkin lymphoma is closely correlated with Epstein-Barr virus infection. However, the low rate of EBV infection detected in childhood non-Hodgkin lymphoma might be due to heterogeneous distribution of pathological types in this study.

OBJECTIVETo investigate the dynamic expression of TPM1 in rat model of hepatic fibrosis and hepatic stellate cells induced by TGFβ1.

METHODThirty male SD rats were divided into control group (n = 6) and model group (n = 24). The rat model of hepatic fibrosis was established by intraperitoneal injection of dimethylnitrosamine(DMN). The sera were collected from portal vein and liver tissues were taken from animals 2, 4, 6, 8 weeks HSC-T6 cells were cultured and induced 48 hours by 5 ng/ml TGF-β1. The pathological changes of liver were observed by Hematoxylin-Eosin and Masson Staining. Reverse Transcription-polymerase chain reaction (RT-PCR), immunohistochemistry and Western-blotting were used to determine the mRNA and protein expressions of TPM1, TGFβ1 and α-SMA in rat models and HSC-T6 cells and the localization of TPM1 in rat models.

RESULTSRat models of hepatic fibrosis were successfully established. TPM1 was lowly stained in the wall of blood vessels in portal areas in normal livers, in fibrotic livers TPM1 was mainly stained along the fibrotic septum. The mRNA and protein expressions of TPM1 and α-SMA in rat models of hepatic fibrosis increased at the week 2 and peaked at week 6, which was statistical significance compared to control group, P < 0.05; TGF-β1 increased at week 2 and it was higher than the levels in other groups at week 4, which was statistical significance compared to control group P < 0.05; Correlation analysis showed that TPM1 positively correlated with α-SMA and TGF-β1, rs = 0.688, rs = 0.692, P < 0.01. In HSC-T6, the mRNA expressions of TPM1 and α-SMA increased after being induced by TGF -beta1. compare with control group, the differences were significant, P less than 0.05.

CONCLUSIONTPM1 may be playing an important role in the occurrence and development of liver fibrosis. Maybe it could become a potential therapeutic target for hepatic fibrosis.

To study the effect of Siwu decoction on the function and expression of P-glycoprotein (P-gp) in Caco-2 cells. The Real-time quantitative poly-merase chain reaction (Q-PCR) was used to analyze the mRNA expression of MDR1 gene in Caco-2 cells. Flow cytometer was used to study the effect of Siwu decoction on the uptake of Rhodamine 123 in Caco-2 cells, in order to evaluate the efflux function of P-gp. Western blotting method was used to detect the effect of Siwu decoction on the P-gp protein expression of Caco-2 cells. Compared with the blank control group, after Caco-2 incubation with Siwu decoction at concentrations of 3.3, 5.0, 10.0 g x L(-1) for 24, 48, 72 h, the mRNA expression of MDR1 was up-regulated, suggesting the effect of Siwu decoction in inducing the expression of MDR1. After the administration with Siwu decoction in Caco-2 cells for 48 h, the uptake of Rhodamine 123 in Caco-2 cells decreased by respectively 16.6%, 22.1% (P < 0.05) and 45.4% (P < 0.01), indicating that the long-term administration of Siwu decoction can enhance the P-gp efflux function of Caco-2 cells. After the incubation of Caco-2 cells with Siwu decoction for 48 h, the P-gp protein expression on Caco-2 cell emebranes, demonstrating the effect of Siwu decoction in inducing the protein expression of P-gp.

Objective To identify the factors that influence the prognosis and particularly the survival of patients with corpus callosal gliomas. Methods A retrospective analysis of the clinical data was conducted involving 60 patients with corpus callosal gliomas treated between January, 1995 and December, 2007. All the patients underwent surgical tumor resection with postoperative radiotherapy and chemotherapy. Kaplan-Meier and Cox regression model were used to evaluate the possible prognostic factors including the patients' gender, age, preoperative Karnofsky performance status (KPS), tumor locations, preoperative epilepsy, histological grade, enhancement pattern on magnetic resonance imaging (MRI), extent of surgical resection, and tumor size. Results Kaplan-Meier analysis revealed that age, preoperative KPS score, and histological grade had significant influences on progression-free survival (PFS) and overall survival time of the patients. The tumor location had a significant impact on the overall survival time of the patients, but did not obviously affect the PFS. Multivariate analysis with the Cox regression model indicated that age, histological grade, and extent of surgical tumor resection significantly influenced the overall survival time of the patients, and age and histological grade of the tumor significantly affected the PFS. Conclusion A younger age, lower pathological grade and radical surgical resection of the tumor are the protective prognostic factors in patients with corpus callosal gliomas, while gender, tumor size, tumor location, and KPS score before operation have no prognostic significance.
