To improve the diagnosis of concomitance of cancer and cyst in the same kidney, a retrospective review of the imaging results of 10 patients with cystic renal cancers confirmed by surgery and pathologic study was performed. Excretory urography showed an avascular mass suggestive of a cyst. Ultrasonography revealed a cystic mass with thinkened and irregular walls,but it was unable to distinguish between a complicated and an extensively necrotic cancer.On CT scans,irregular cystic wall and definite early enhancement in solid component were observed.In some of the patients,there were mural nodules,septum and calcification. Some scans may show an almost cystic appearance,but one or more CT scans always showed some dense neoplastic tissue.This study indicated irregular and thickened cystic wall and septum,mural nodules and early enhancement of solid component were the characteristic findings for the CT diagnosis.This suggestive CT pattern must be particularly searched for at the base of the cyst,but may also be present in the periphery of the cyst.

MicroRNAs(miRNA)are a kind of small non -conding RNA,which negative regulate target genes expression at post -transcription level by binding 3'-untraslation region(3'UTR).Dysregulation of miRNA pro-files relate to cancer,immune disorders,cardiovascular disease,neurodegenerative diseases and metabolic diseases. miR -221 /222 are two similary miRNAs,which share the same promoter and have the same seed sequence.miR -221 /222 usually target to same target genes and co -regulate same processes and act as onco -miRNA roles.Howev-er,miR -221 /222 maybe act as suppressor in cancer which maybe dependent particular context.The roles of miR -221 /222 are reviewed in this article,will provide a comprehensive vision for comprehending the biological process of miR -221 /222 in carcinoma.

BACKGROUND: Botulinum toxin A has been applied to treat muscular convulsion by local injection and shows obvious effects in reducing muscular hypertonia with fewer side effects.OBJECTIVE: To assess the effect of botulinum toxin A on Meige's syndrome concerning facial convulsion, therapeutic effect, and side effects.DESIGN: Randomized self-control clinical study.SETTING: Neurological Department of Southwest Hospital Affiliated to the Third Military Medical University of Chinese PLA.PARTICIPANTS: Between June 2000 and May 2003, 24 outpatients were confirmed of having Meige's syndrome at the Neurological Department of Southwest Hospital, the Third Military Medical University of Chinese PLA and volunteered to receive botulinum toxin A (BTA) injection. Meige's syndrome was presented by convulsive eyelid closure in 10 cases, grinding teeth and smacking movement in 3 cases, involuntary blinking in 2 cases,frowning in 1 case, and mixed manifestations in 8 cases.METHODS: Totally 24 patients with Meige's syndrome were subjected to BTA injection at multiple spots of convulsive muscles by dosage of 2.5-5 U in each spot. Improvement of facial convulsion and curative effects were assessed at least once by clinical examination or telephone follow-up. Convulsion was graded in four degrees according to Cohen's scaling standard.Curative effects: [1] Complete alleviation: Convulsion was reduced to grade 0. [2] Obvious alleviation: Convulsion dropped by more than two grades. [3]Partial alleviation: Convulsion dropped by one grade. [4] Ineffective: Convulsion was not attenuated.MAIN OUTCOME MEASURES: [1] Changes of muscular convulsion intensity after BTA injection in patients with Meige's syndrome; [2] improvement of various symptoms after BTA injection; [3] side effects of BTA.RESULTS: Totally 24 patients entered the result analysis. [1] Before treatment, there were one case of grade 0- Ⅰ, 7 cases of grade Ⅱ, 10 cases of grade Ⅲ and 6 cases of grade Ⅳ, as compared to 16, 6, 2 and 0 cases, respectively, after treatment (χ2 = 95.489 4, P = 7.313 41×10-10). [2] BTA could alleviate eyelid convulsion in an average of 3 days, with curative effect reaching the peak in 2 weeks. Symptoms were found to be completely alleviated in 75% (18/24), obviously alleviated in 17% (4/24) and partially alleviated in 8% (2/24), with the total efficiency of 100%. The effective duration was 8-44 weeks with the average of 24.4 weeks. [3] Muscle weakness at the injected spot and incomplete muscular paralysis at the uninjected spots occurred for a short time after injection, but were alleviated automatically within 1-8 weeks.CONCLUSION: BTA can obviously reduce convulsive degree and enhance the effects in treating Meige's syndrome; moreover, selection of muscles to be injected into and injection spots will help reduce side effects.

Objective To investigate the mid-term effect of SolitaireAB stent-assisted interventional embolization with spring coils for the treatment of intracranial wide-necked aneurysms. Methods During the period from May 2009 to April 2013, a total of 49 patients with intracranial wide-necked aneurysm (49 aneurysms in total) received SolitaireAB stent-assisted interventional embolization treatment at authors’ hospital. In 41 patients, a total of 41 aneurysms were detected, of which ruptured aneurysm with bleeding was confirmed in 26 and un-ruptured aneurysm in 15. These 41 patients were followed up for 12-48 months. Based on modified Rankin scoring and DSA, CTA or MRA manifestations, the clinical results were evaluated. Results After the embolization treatment, re-bleeding of the aneurysm occurred in 2 cases, cerebral infarction in 3 cases, occlusion of the parent artery in one case and death in one case; the occurrence rate of complications was 14.2%. DSA, MRA or CTA performed at 12 months after the embolization treatment, showed that 32 aneurysms (78.0%) were completely obstructed, which was obviously higher than that observed on DSA performed immediately after the embolization procedure (21 aneurysms, 42.9%), the difference was statistically significant (P=0.02);residue of aneurismal neck was seen in 7 cases (17.1%) and partial occlusion in 2 cases (4.9%), which were much better than those observed on DSA that was performed immediately after the embolization procedure. Twenty-four aneurysms (58.5%) remained stable, showing no any change, and recurrence of aneurysm was observed in 4 cases (9.7%). At the last follow-up exam, the modified Rankin scoring showed that 0 point was seen in 18 cases (43.9%), one point in 10 cases (24.4%), 2 points in 5 cases (12.2%), 3 points in 4 cases (9.8%), 4 points in 2 cases (4.85%) and 5 points in 2 cases (4.85%). The self-care rate for daily activities was 80.5%, the prognosis was good. Conclusion For the treatment of intracranial wide-necked aneurysms, SolitaireAB stent-assisted interventional embolization with spring coils is safe and effective. This technique can improve the embolization rate and reduce the procedure-related complications.

Objective To analyze the correlation between serum interleukin (IL)-33 and early rheumatoid arthritis (RA) by testing the serum IL-33 of patients with RA.Methods One hundred patients with early RA whose disease duration was less than 1 year were selected,40 patients with osteoarthritis (OA) and 70 healthy controis were selected.The serum IL-33 levels of the three groups were detected by enzyme-linked immunosorbent assay (ELISA).The correlation between serum IL-33 levels and clinical features of patients with RA were analyzed.Kruskal-Wallis test,Mann-Whitney U test,X2 test and Spearman correlation analysis were used for statistical analysis. Results The level of serum IL-33 in RA patients [(282±871)pg/ml ] was significantlv higher than that of the healthy controls [(7±38) pg/ml,P

Objective To investigate the hemodynamic change of venous leakage in venogenic impotence. Methods Thirty-two patients with vasculogenic impotence were evaluated with conventional penile duplex sonography with spectral analysis and color Doppler imaging after intracavernosal injection of PGE1 to induce an erection.The color Doppler appearance of deep dorsal vein of penis,cavernous veins and bulbourethral vein wen observed and the correlativity with resistance index(RI)of cavernous artery were analyzed. Results After five minutes following intracavernous injection,the flow and diameter of the penis vein were continuous increased.The coefficient correlation r between the discharge of deep dorsal vein of penis,cavernous veins and bulbourethral vein with RI of cavernous artery were-0.55,-0.53,-0.24(P＜0.05).Considering the existence of mixed venous leakage,r between the discharge of vein of penis with RI of cavernous artery was-0.88(P＜0.001).Conclusions Higher qualitative ultrasound imaging could demonstrate venous leakage sensitively and assess the location and degree of venous leakage in venogenic impotence initially.
