Objective To investigate the clinical and pathological characters and seize the diagnostic main points of minimal deviation adenocarcinoma of cervix to improve the accuracy of pathological diagnosis. Methods A clinic pathological review of 6 cases with minimal deviation adenocarcinoma was analyzed retrospectively. Results The main clinical symptoms were watery leucorrhagia, enlargement of the cervix with erosin and hardening. The pathological findings included hyperplasic and mild abnormality of the glands, invasion effects into the stroma could be observed in some glands and abortive glands with desmoplastic changes, or edema and inflammatory infiltration around the glands were also observed. Conclusion The detection rate of minimal deviation adenocarcinoma may increase by triple combination of clinic, cytology and histology.

The status of bioelectrical impedance measurement especially the multifrequency segmental bioelectrical impedance measurement of liver diseases is introduced.The multifrequency segmental bioelectrical impedance can well rule out the impact from the change of body weight caused by edema and ascites,and can evaluate the volume of ascites.Compared with single frequency bioelectrical impedance,the multi frequency bioelectrical impedance measurements probably display good prospect.It helps to produce objective judgement on nutrition status and energy metabolism for patients with liver diseases.The effect,however,needs further clinical research.

There are about 150 million people around the world with chronic hepatitis C virus (HCV)infection currently,of whom 20%will ultimately progress to cirrhosis and eventually die of end-stage liver disease and hepatocellular carcinoma.Interferon (IFN)has long been recognized as the cornerstone of the treatment of chronic hepatitis C because of its role in sustained virologic response and prevention of disease progression.However,it has limited efficacy and multiple adverse effects.In recent years,direct-acting antiviral agents (DAAs) have shown good efficacy.This review summarizes the recent advances in IFN-free anti-HCV therapeutic regimens based on DAAs.We believe that,with the emergence of DAAs,IFN-free therapies will develop rapidly and display better prospects.

In recent years, with the advances in life cycle of hepatitis C virus (HCV) and the approval of direct-acting antiviral agents (DAAs), great progress has been made in treatment of chronic hepatitis C (CHC).This article reviews the research progress of DAAs in CHC management, showing the possibility of the elimination of HCV infection by DAAs.DAAs have not been widely clinically used due to high medication costs, but can be used as a supplement for the combination therapy of pegylated interferon and ribavirin.

Objective To observe the clinical characteristics and efficacy of laser photocoagulation of aggressive posterior retinopathy of prematurity (AP-ROP).Methods Twenty-eight eyes of 14 infants with AP-ROP from May 2008 to December 2010 were enrolled in this study.The infants were examined using RetCam photography and indirect ophthalmoscopy.Among the 28 eyes,24 eyes were classified as zone one and 4 eyes zone two.All eyes were treated within 24 hours using binocular indirect ophthalmoscope and laser photocoagulation.The initial energy was 200 mW,using energy was 200 - 500 mW,exposure time was 200 ms.Every two photocoagulation spot was linked together,but no overlap.Follow-up ranged from 3 to 24 months,with a mean of 11.5 months. The retinal bloods,the iris surface vessels,the fiber hyperplasia on retina,retinal detachment or ruffle form were observed.Results Twenty-five of 28 eyes (89.3 ％) recovered or were classified as control; 1 of 28 eyes (3.6 ％) was suffered retinal detachment one month after treatment.The detachment was resolved through vitrectomy Surgery.Two of 28 eyes (7.1 ％)did poorly.The parents gave up treatment resulting in loss of vision.No treatment-related complications were observed during the follow-up period,such as damage to cornea,iris and lens. Conclusion Photocoagulation is a safe and effective way to treat most AP-ROP.

Objective To investigate the changes of ultrastructure and Bax,Bcl-2 expression of cerebral cortex in lymphostatic encephalopathy(LE).Methods LE models were established by occluding and removing both the shallow and deep cervical lymph nodes in rats.Ultrastructural changes of the cerebral cortex were observed at 1 d,2 d,3 d,5 d,7 d and 14 d after operation.Expression of Bax and Bcl-2 were examined by Western blot.Results Brain edema appeared under electron microscope in LE model group.The perivascular spaces in the cortex were enlarged and full of fluid,the dropsical nerve fibers had swelling and fragmented myelin sheath.Some neurons showed apoptotic conformation and some had characters of necrosis.The changes mentioned above were the most serious at day 5.The protein expression of Bax,Bcl-2 and the ratios of Bax/Bcl-2 in LE 3 d,5 d,7 d groups were significantly higher than those in normal control group(all P

BACKGROUND:Studies have found that sodium arsenite can cause the malignant transformation and tumorigenicity of HaCaT cels, but whether low concentrations of sodium arsenite can cause the malignant transformation is rarely reported.
OBJECTIVE:To study the effect of sodium arsenite on the malignant transformation of human immortalized keratinocyte cel lines.
METHODS:HaCaT cels were treated with different concentrations of sodium arsenite. MTT assay was used to determine the effect of sodium arsenite on HaCaT cel morphology and proliferation, flow cytometry used to detect the effect of sodium arsenite on HaCaT cel cycle, and soft agar colony formation experiments assay used to determine the effect of sodium arsenite on HaCaT cel colony formation capacity.
RESULTS AND CONCLUSION: HaCaT cels grew wel when the concentration of sodium arsenite was 5 mol/L, but the cel growth was inhibited under intervention with 10 and 50 mol/L sodium arsenite. HaCaT cels treated with 0.1 mol/L sodium arsenite were passaged to the 20th generation, and cel morphology had no notable changes; cels at passage 25 exhibited enlarged size and multiple nucleoli, which had a continued proliferation trend. Compared with the primarily cultured cels, 0.1 mol/L sodium arsenite-treated HaCaT cels at passages 15 and 25 had an increased proportion at S phase and G2/M phase, with strengthened proliferation ability and increased colony-forming efficiency, and moreover, the proliferation ability and colony-forming efficiency of passage 25 cels were higher than those of passage 15 cels. These experimental data show that high concentrations of sodium arsenite reduce HaCaT cel viability, and low concentrations of sodium sulfite have a certain influence on the morphology, cel cycle, proliferation ability and colony-forming efficiency of HaCaT cels, and moreover, the proliferation ability and colony-forming efficiency of human immortalized keratinocytes wil be strengthened with the increase of passage.

Objective To investigate the association of restriction fragment length polymorphisms (RFLP) in p.S267F of SLC10A1 gene with clinical outcomes of hepatitis B virus (HBV) infection. Methods Clinical data of 1 268 patients with HBV infections admitted in Public Health Clinical Center Affiliated to Fudan University during July 2014 and February 2015 were collected.Polymerase chain reaction-restriction fragment length polymorphism ( PCR-RFLP) method was used to genotype the p .S267F of SLC10A1 gene in all patients, and the potential association between variants in p .S267F of SLC10A1 gene and the clinical outcomes of HBV infection was analyzed .Results Among 1 268 patients with HBV infections, 1 226 were of genotype CC, and 42 were of genotype CT, so the variation rate in p.S267F was 3.31%(42/1 268).Compared with patients with genotype CC , patients with genotype CT had a higher incidence of acute HBV infections (13.6%vs.28.6%,χ2 =19.819, P<0.05) and a lower incidence of HBV-related liver cirrhosis or hepatocellular carcinoma (13.9% vs.4.8%, χ2 =18.945, P <0.05). Conclusion RFLP in p.S267F of SLC10A1 gene may be associated with chronicity and aggravation of HBV infection, and genotype CT is possibly a protective factor .
