Objective To compare the efficacy of pirarubicin with other intravesical chemothera peutic agents in preventing bladder tumor recurrence. Methods Databases such as Medline,EM Base,CBMDisc and PubMed,ScienceDirect,LWW,Springer,CJFD(Chinese Journal Fulhext Data base)and Chinese Periodicals Database of Science and Technology were systematicallv searehed for controlled studies involved with intravesical pirarubicin for the treattnent of bladder cancer.Eligible studies according to inclusion and exclusion criteria were selected,then recurrence data from included studies were retrieved for a meta-analysis. Results Fifteen studies met the inclusion criteria.Of these studies 10 compared efficacy of pirarubicin with mitomycin C,and the meta-analysis based on these 10 studies showed that pirarubicin was statistically superior to mitomycin C(OR=0.41,95%CI 0.27～0.61,P＜0.01).Of 6 studies,pirarubicin was compared with thiotepa(OR=0.35,95%CI 0.11～1.13,P＞0.05),adriamyein(OR=0.15,95% CI 0.03～O.76,P＜0.05),epirubicin(OR=0.53,95% CI 0.23～1.23,P＞0.05),hydroxycamptothecin(OR=0.25,95% CI 0.10～0.64,P＜0.05)and blank control respectively,statistical analysis indicated pirarubicin was significantly better than adriamycin,hydroxycamptothecin and blank control,and not statistically different from thiotepa and epirubicin. Conclusion Pirarubicin is effective in preventing bladder tumor recurrence,with efficacy better than chemotherapeutic agents such as mitomycin C,hydroxyeamptothecin,and adriamycin,thus can be a novel optional intravescial chemotherapeutic agent for bladder cancer.

Objective To explore the efficiency of arterial perfusion chemotherapy combined with embolization for the treatment of giant carcinoma of the kidney. Methods Arterial perfusion chemotherapy combined with embolization was performed through the renal artery in 21 cases of giant carcinoma of the kidney from April 1992 to April 2006. The chemotherapeutic agents contained carboplatin(300 mg), mitomycin(20 mg) and cyclophosphamide(800 mg). The embolization was conducted with anhydrous alcohol, sodium morrhuate, and lipiodol plus gelatin sponge. Results The arterial perfusion with embolization was successfully obtained in all 21 cases. Surgical resection was accomplished in 15 cases, 1 - 8 weeks after the embolization; revealing severely less or no blood supply to the tumor. Pathological findings showed marked necrosis of tumor cells with peripheral inflammatory infiltration, fibrous proliferation as well as capillary embolization. The survival rates at 1-, 2-, and 3-, year were 80%(12/15), 53.33%(8/15) and 40%(6/15) respectively. Conclusions Combination of perfusion chemotherapy and embolization through the renal artery for the treatment of giant carcinoma of the kidney offers promising clinical effects.

Intraocular pressure detection has a great significance for understanding the status of eye health, prevention and treatment of diseases such as glaucoma. Traditional intraocular pressure detection needs to be held in the hospital. It is not only time-consuming to doctors and patients, but also difficult to achieve 24 hour-continuous detection. Microminiaturization of the intraocular pressure sensor and wearing it as a contact lens, which is convenient, comfortable and noninvasive, can solve this problem because the soft contact lens with an embedded micro fabricated strain gauge allows the measurement of changes in corneal curvature to correlate to variations of intraocular pressure. We fabricated a strain gauge using micro-electron mechanical systems, and integrated with the contact lens made of polydimethylsiloxane (PDMS) using injection molding. The experimental results showed that the sensitivity was 100. 7 µV/µm. When attached to the corneal surface, the average sensitivity of sensor response of intraocular pressure can be 125.8 µV/mm Hg under the ideal condition.

Objective To investigate the metabolic profile of uric acid and the significance of the altered renal expression of urate trans-porter 1(URAT1) in patients with uric acid nephrolithiasis. Methods The data of 24 patients in our hospital from January 2012 to October 2013 were analyzed retrospectively. Participants in the research were divided into three groups:patients with uric acid nephrolithiasis,other patients with nephrolithiasis and normal participants. The basic clinical data and the related data of uric acid metabolition of participants were collected,URAT1 gene expression in renal tissures of three groups was detected by Real-time PCR technique. All data were statistically ana-lyzed and compared between these groups. Results Uric acid levels in plasma,body mass index and age were significantly higher in patients with uric acid nephrolithiasis than other two groups (P<0. 05),but urine PH value was significantly reduced in patients with uric acid neph-rolithiasis. Urine and uric acid output of 24 hours urine were no significant difference among the three groups (P>0. 05). The result of Real-time PCR suggested that the URAT1 renal expression was significantly higher in patients with uric acid nephrolithiasis than other two groups (P<0. 05). Conculusion Patients with uric acid nephrolithiasis are closely related with hyperuricemia,but unrelated with renal over-ex-cretion of uric acid. The upregulated URAT1 expression in the kidney may be an important molecular mechanism of the clinical features.

Objective To assess the effects of septal anterior ventricular exclusion(SAVE)procedure on left ventricular(LV)shape,volume and function in patients with post-infarction LV anterior aneurysm by intraoperative transesophageal echocardiography(TEE).Methods Twenty patients with LV anterior aneurysm underwent surgical ventrieular restoration(SVR)with the SAVE procedure.Intraoperative TEE was performed before cardiopulmonary bypass(CPB)and after weaning from CPB.LV volume and ejection fraction(EF)was measured using the biplane Simpson's method.LV end-diastolic and end-systolic volumes,indexed by body surface area(EDVI and ESVI,respectively)were calculated.To estimate the shape of LV,end-diastolic sphericity index(SI)of LV was determined.Results Compared with pre- CPB,after SVR,LV shape became more elliptical:SI increased from 0.76±0.04 to 0.84±0.05,P＜0.001.LV size became more normal:EDVI decreased from(121.51±16.91)ml/m2 to(60.27±9.93)ml/m2,P＜0.001,and ESVI decreased from(85.81±15.02)ml/m2 to (32.44±5.36)ml/m2,P＜0.001,respectively.EF was increased significantly:(46.02±3.90)% vs(29.52±6.0)%,P＜0.001.Conclusions The SAVE technique is easy to reshape LV to ellipsoid fogln and normal size and the resultant improved configuration may contribute to improving EF for patients with post-infarction LV anterior aneurysm.
