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.

Thirty-one cases of limb pain after wind-stroke were treated by direct moxibustion with small moxa cones. Results showed that 12 cases got remarkable effects, 15 cases effect and 4 cases ineffectiveness, with a total effective rate of 87.1%.

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.

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

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 compare the myocardial enzyme spectrum of native mountain yaks ( Bos grunniens) , alien mountain yellow cattle ( Bos taurus domestica) and low altitude yellow cattle breeding in Qinghai plateau, explove the mechanism that the native mountain yaks adapt to the plateau environment.Methods The samples were treated by cervical bleeding to death, and whole blood was collected.Then serum were prepared from whole blood.The myocardial enzymes including aspartate amino transferase, creatine kinase, creatinine kinase-MB isoenzyme, lactate dehydrogenase, α-hydroxybutyrate dehydrogenase and.Results In the native mountain yaks and in the alien mountain yellow cattle, levels of AST, CK, CK-MB were significantly higher than those in the low altitude yellow cattle (P<0.05);compared with the alien mountain yellow cattle, levels of AST,CK were significantly higher than those in the native mountain yaks (P<0.05),CK-MB,LDH and HBDH were lower(P<0.05).The results suggested that under the high altitude and hypoxia environment, myocardial cell injury occurred in the alien mountain yellow cattle, thus various enzymes penetrated through the cells into the blood circulation, lead to the higher serum enzymatic levels.Conclusion The phenomenon indicates that the alien mountain yellow cattle is in a state of high altitude acclimatization.But the native mountain yaks are well adapte to the high altitude and hypoxia environment.

Purpose To investigate the expression of RNF2 in breast disease tissues and cell lines,and to analyze the association between expression of RNF2 and clinicopathological characteristics in breast carcinoma.Methods Expression of RNF2 protein and mRNA levels was detected using immunohistochemistry of EnVision two-step and qRT-PCR in breast carcinoma and benign breast disease as well as in cell lines.Results RNF2 expression was sigmificantly higher in breast carcinoma tissue specimens compared with benign breast disease specimens (P ＜0.05).Besides,the expression of RNF2 protein was significantly associated to tumor size,lymph node status and TNM stage (P ＜ 0.05 for both),but was not related to age,histological grade,the expression of ER,PR and HER-2 (P ＞ 0.05 for both).Higher expression of RNF2 mRNA was detected in breast carcinoma cell lines compared with breast epithelial cell lines (P ＜ 0.05).Conclusion RNF2 is overexpressed in breast carcinoma and can be a potential therapeutic target for breast carcinoma.

Objective To evaluate the effect of propofol on autophagy during oxygen-glucose deprivation and restoration (OGD/R) in human liver cells.Methods Human hepatic HL-7702 cells at the logarithmic growth phase were seeded into culture plates and randomly divided into 3 groups (n =12 each) using a random number table:control group (group C),OGD/R group,and propofol + OGD/R group (group P+OGD/R).The cells were cultured in normal culture medium in group C.In OGD/R and P+OGD/R groups,the cells were subjected to O2-glucose deprivation for 6 h followed by restoration of O2-glucose supply for 12 h.Propofol with a final concentration of 50 mmol/L was added at 10 min before oxygen-glucose deprivation.The cell viability was detected by MTT assay.The expression of autophagy-related proteins such as microtubule-associated protein light chain 3 (LC3) and Beclin-1 was evaluated by Western blot.Immunofluorescence was used to determine the number and distribution of autophagosomes.Results Compared with group C,the cell viability was significantly decreased,the expression of LC3 and Beclin-1 was significantly up-regulated (P＜0.05),and the number of autophagosomes was significantly increased in OGD/R and P+OGD/R groups.Compared with group OGD/R,the cell viability was significantly increased,the expression of LC3 and Beclin-1 was significantly down-regulated (P＜0.05),and the number of autophagosomes was significantly decreased in group P+OGD/R.Conclusion The mechanism by which propofol reduces OGD/R injury is probably related to inhibition of autophagy in human liver cells.
