Objective To analyze the clinical and pathological data of the minimal deviation adenocarcinoma (MDA) of the cervix, and to provide evidence based medicine for diagnosis and treatment. Methods Clinical case reports about MDA or malignant adenoma during 1980-2014 published on CNKI, WanFang, CBM, WeiPu and Medline were retrieved and combined with 2 case with the same diagnosis and treatment. Results Age of onset was 20-86 years old, and the average age was 44.8 years, with median age of 44.5 years. Clinical symptoms of MDA showed massive vaginal apocenosis or irregular bleeding. Gynecological examination common showed cervical hypertrophic and harden. The positive rate of cervical cytology examination was 9.73% (11/113). MDA diagnosed by cervical biopsy and conization accounted for 58.38% (108/185). Immunohistochemical showed that the positive rates of carcinoembryonic antigen, P53 and Ki-67 were 93.91%(108/115), 75.44%(43/57)and 100.00% (42/42). Main operation assisted with postoperative radiotherapy and chemotherapy, early diagnosis, clinical stage and operation methods played important roles in the prognosis. Conclusions The clinical symptoms and physical signs are not obvious for MDA which is difficult to diagnose, so it is easy to diagnose mistakenly and misdiagnose also. The positive rate of cervical cytology is usually lower, repeated and deep cervical biopsy or conization combined with immunohistochemistry can improve the accuracy of diagnosis. The individualized treatment should be selected according to clinical stage for the patients who were confirmed preoperatively.

Objective To investigate the role of losartan in AT2-R mediated renal protective effects in renovascular hypertension rat. Methods Male SD rats were divided into sham group and renovascular hypertension group in which Goldblatt methods were performed. The two groups were intragastically administered with losartan (respectively 0, 10, 20, 30 mg?kg-1?d-1) for 6 weeks. Then renal function was measured, the AT2-R expression in the non-ischemic kidney and the AngⅡ contents in non-ischemic kidney and plasma were determined. Results In renovascular hypertension rats, especially in the contralateral, non-ischemic kidney, the expression of AT2-R protein were up-regulated. Losartan increased the AngⅡ contents in non-ischemic kidney and plasma, mediated the natriuretic/diuretic effect and renal protective effect in renovascular hypertension rat and increased the expression of renal AT2-R. Conclusion In renovascular hypertension rat, losartan mediates renal natriuretic/diuretic effect and protects renal function through up-regulating AT2-R in kidney.

Objective To investigate the value of transcatheter arterial embolization in the treatment of obstinate nosebleeding. Methods Twenty patients with obstinate nosebleed failed with conventional therapy were performed internal maxillary arterial angiography. Transcatheter arterial embolization were carried out immediately after occurance of nosebleeding. PVA or gelfoam particles were injected into the bleeding arteries under fluoroscopy control. Nasal packing was removed to see whether bleeding was stopped. Results Active bleeding occurred in all 20 patients during angiography but was stopped in all patients after embolization without severe complications. Conclusions Transcatheter arterial embolization is an useful mini-invasive method in the treatment of obstinate nosebleeding.

OBJECTIVE:To evaluate clinical utilization and blood concentration monitoring of vancomycin in our hospital. METHODS: By retrospective survey method, the clinical information (primary diseases, bacteriological culture, blood concentration of vancomycin, clinical efficacy, renal function) of 41 inpatients who had been treated with vancomycin and their blood concentrations from Nov. 2005 to Dec. 2008 were analyzed statistically. RESULTS: The total response rate of vancomycin was 65.0%. The peak concentration of 62.7% cases were below 25 mg?L-1 while the valley value of 55.2% cases were below 5 mg?L-1. The incidence of renal dysfunction after treatment was 12.2%. CONCLUSION: The consumption and blood concentrations of vancomycin are close to low level in our hospital. It should be paid attention to the blood concentration monitoring of vancomycin to achieve an ideal individual administration according to clinical practice.

Objective To introduce the current progress of research on pancreatic encephalopathy(PE). Methods Collecting related articles to make this paper.Results (1) The reported incidence of PE was from 11% to 53%. (2).The main pathogenisis of PE was large quantity of enzymes, which were secreted by the pancreas, entering the blood and crossing the blood brain barrier resulting in brain damage. (3).The demyelination could be seen on the brain pathologically. (4).The main clinical features of PE were temporal confusion, coma and neurasthenic syndrome. (5).The treatments of PE include treating underline disease, trying gabexale mesilate(Foy), a new special enzyme inhibitor, and the symptom control treatment. Conclusions PE is a dangerous complication of pancreatitis with a very bad prognosis. Evaluated myelin basic potein(MBP)may be a early, reliable biochemical parameter for diagnosis of PE. A special enzyme inhibitor Foy may be very useful in treating PE.

TNF in sera from BALB/c mice treated with sepia was detected by L929 cell killing assay. Sera of the mice treated with saline were used as control. Results showed a significant TNF -inducing activity of sepia in animals. And the induced sera were also cytotoxic to human cancer cells,such as GM803 and Y99.

OBJECTIVE: To probe into the causes of drug repercussion of inpatients in psychiatric hospital to promote rational drug use. METHODS: Using HIS (hospital information system), the drug repercussion data in 8 psychiatirc departments (ward pharmacy) between 2004 and 2005 were analyzed statistically. RESULTS: Of the total 203 drug repercussion cases analzyed, most were resulted from alteration of doctor’s orders, man-made entry errors of drug information, and high drug costs etc. CONCLUSION: The effective way to reduce drug repercussion is to improve technical level and working attitude, establish good rules and regulations and standardize service conditions.

Objective This study investigated magnetic resonance imaging (MRI)manifestations and pathological changes after aquaporin-4 (AQP4)gene silencing in treatment of early cerebral infarction.Methods Ninety adult Wistar rats were randomly divided into con-trol group,infarction group and treatment group.All the above groups were assigned to five sub-groups according to the time point:0.5,1,2,4 and 6 hours,respectively (n= 6 for each group).For the right middle cerebral artery occlusion (MCAO-infarction group),the rats were separately injected with short hairpin RNA-AQP4 liposome (shRNA-AQP4+MCAO-control group)and in-terference agents (siRNA-AQP4 + MCAO-interference group).The rats in all groups were examined with T2 weighted image (T2 WI)and diffusion-weighted imaging (DWI).The rs-T2 WI,rs-DWI and relative apparent diffusion coefficient (ADC)of the big-gest high-signal-intensity layer on T2 WI and DWI were measured.Corresponding brain tissue was collected for pathological observa-tion.The data were analyzed using SPSS 13.0 software.Results Identical changes were detected between control and infarction groups.The high-signal intensity was found on DWI at 0.5 hour and on T2 WI at 2 hours after MCAO.rs-DWI and rs-T2 WI in-creased with time.The value of relative ADC decreased quickly within 2 hours after MCAO,and cytotoxic edema was significantly aggravated.The value of relative ADC increased slowly at 4 and 6 hours,but angioedema was detected during this period.There was significant change in relative ADC between the treatment and control groups at 0.5 to 4 hours (P < 0.01)and cytotoxic edema was significantly lightened.But there was no significant difference in relative ADC between treatment and control groups at 6 hours (P >0.05).However,angioedema was visible in this group at 6 hours.Above results confirmed that during early cerebral in-farction,the differential regions of DWI and T2 WI high-signal area were considered as cytotoxic edema,which was the pathologic basis of the decreased ADC values.AQP4 gene silencing could effectively reduce cytotoxic edema.Conclusion DWI and ADC value could reveal timely and exactly therapeutic outcomes of cytotoxic edema.The high-signal intensity on T2 WI represents angioedema, and AQP4 gene silencing has no obvious change.
