Objective To discuss the efficacy and safety of triamcinolone acetonide (TA)retrobulbar injection combined with panretinal photocoagulation (PRP)in the treatment of diabetic macular edema (DME), and to explain the advantages of this combination treatment method in treating DME.Methods Sixty-four cases (64 eyes) with macular edema due to diabetic retinopathy(DR)were randomly divided into combination treatment group(n=34,treated with TA retrobulbar injection combined with PRP)and PRP group(n=30,received PRP treatment only).The changes in the best corrected visual acuity (BCVA), the fovea centralis thickness (CMT), and the intraocular pressure(IOP)before treatment and in 1 month, 3 months, 6 months after treatment were compared. Results The BCVA was improved in both groups after treatment. However, the BCVA improvement in combination treatment group was statistically more significant (P<0.05)compared with PRP group in 1 month, 3 months and 6 months after treatment. The resolution of DME after treatment as compared with that before treatment,the CMT reduced in two groups in 1 month,3 months,6 months after treatment.At each stage,the CMT in combination treatment group was lower than PRP group (P<0.05 ). No complications of glaucoma, cataract,vitreous hemorrhage,retinal detachment,choroidal detachment,and endophthalmitis were found in all patients.Conclusion For the patients with DME,the combination treatment with TA retrobulbar injection and PRP has a better therapeutic effect than the sole PRP treatment in reducing the macular edema and improving the BCVA.The operation is simple and has less complication.

Background and purpose: Because of the aggressive nature of hilar cholangiocarcinoma and the absence of effective adjuvant therapy, surgical radical resection offers hilar cholangiocarcinoma patients the only choice. Research focus include preoperative assessment, the use of preoperative biliary drainage, the range of hepatic resection, and the range of lymphadenectomy. To investigate the clinical experience and efifcacy of combined hepatectomy in the treatment of hilar cholangiocarcinoma. Methods: Two hundred and seven patients with hilar cholangiocarcinoma treated surgically in the First Afifliated Hospital of Kunming Medical University form Jan. 2007 to Oct. 2013 were retrospectively analyzed. Results:Of the 207 patients, 125 patients who received radical resection (R0 resection) and the curative resection rate was 60.4%. One hundred and iffty-six cases were treated in combined hepatectomy group, 51 cases in non-hepatectomy group, the rate of R0 resection was 70.5%in hepatectomy group and 29.4%in non-hepatectomy group, and the difference was signiifcant (P<0.01). Two patients died perioperatively, the main postoperative complications included hepatic function insufifciency and bile leakage. One hundred and seventy-two patients were followed up, the median survival time of the 102 patients who received R0 resection was 45 months, and the 1, 3, 5 year survival rates were 96.1%, 59.1%and 17.2%. The median survival time of the 70 patients who received R1-2 resection was 26 months, and the 1, 3 year survival rates were 81.3%and 19.2%, and none of the patient survived for over 5 years. The survival rate of patients who received R0 resection was signiifcantly higher than those who received R1-2 resection (χ2=39.121, P<0.01). In the hepatectomy group was awarded the R0 resection in patients with postoperative 1, 3, 5 year survival rate was 97.8%, 63.9% and 18.0%, in non-hepatectomy group received R0 resection in patients with postoperative 1, 3, 5 year survival rate was 83.3%, 20.8%and 8.3%. There were signiifcant differences in the postoperative survival rate between both group (χ2=5.988, P=0.014). Conclusion:Radical excision is the key to improve the long term survival. Combined hemihepatectomy and standardized lymph node resection has signiifcantly improved the radical resection rate and the efifcacy of treatment for hilar cholangiocarcinoma.

AIM: Cystostomy is the traditionary method for detecting urodynamic indexes in mice, which de-stroys the continuity of the bladder, and there are significant differences between this method and the clinically used trans-urethral method.This study aims to develop an appropriate urethral catheter to investigate the advantages and application val-ue of transurethral method for urodynamic test.METHODS:A pediatric intravenous catheter was used for urethral catheter-ization on 8 female mice, and linked to connect the catheter to baroreceptor and micropump.The epidural catheter was also used as manometry tube.RESULTS:Using this method, the following urodynamic indicators has been successfully cap-tured:basal bladder pressure (BBP), bladder leak point pressure (BLPP), maximum voiding pressure (MVP), maxi-mum bladder capacity ( MBC ) , post-void residual urine volume ( PVR ) , voiding volume ( VV ) , efficiency of voiding ( EV) and bladder compliance ( BC) .CONCLUSION:This is the first successful simulation used in human body to a-chieve mouse urodynamic testing through the urethra catheter, which avoids the impact of cystostomy on urodynamics in mice, and the mice are able to keep long-term survival after tests for the follow-up molecular and genetic experiments.

Objective To observe any effect of low intensity pulsed ultrasound (LIPUS) on the expression of integrin-focal adhesion kinase (FAK)-mitogen-activated protein kinase (MAPK) mechanochemical transduction pathway-related proteins in the chondrocytes of rabbits with knee osteoarthritis (OA).Methods Of the 18 New Zealand white rabbits selected for the study,twelve received knee anterior cruciate ligament transection to model OA.The remaining 6 rabbits served as normal controls.At the 4th week after modeling the rabbits were sacrificed and chondrocytes were isolated and cultured in vitro.All the cultured cells were randomly divided into three groups:a normal control group (NC),an OA model group (OA) and an OA model plus LIPUS group (OA + LIPUS).When the cells had been cultured to the 2nd passage,the NC group and OA group cells had received no treatment.The OA + LIPUS group cells were exposed to 40 mW/cm2 of LIPUS for 20 min,once a day for 6 days.The expression of collagen protein type Ⅱ,aggrecan,MMP-13,integrin β1 p-FAK and p-p38,p-ERK1/2 and p-JNK Mapks were detected by Western blotting.Results Compared with the NC group,the expression of collagen type Ⅱ and aggrecan was significantly lower in the OA and OA + LIPUS groups,with more significantly lower expression of collagen type Ⅱ and aggrecan in the OA group than in the OA + LIPUS group.Compared with the NC group,the expression of MMP-13 was significantly higher in the OA and OA + LIPUS groups,with a significantly larger increase in the OA group.Compared with the NC group,the expression of integrin β1 and p-FAK was also significantly higher in the OA and OA + LIPUS groups,with a significantly larger increase in the OA + LIPUS group.Compared with the NC group,the expression of p-p38,p-ERK1/2 and p-JNK was also significantly higher in the OA group,but compared with the OA group,the expression of those kinases was,on average,significantly lower in the OA + LIPUS group.Conclusions LIPUS can inhibit the degradation of collagen type Ⅱ and aggrecan,and inhibit the expression of MMP-13,p-p38,p-ERK1/2 and p-JNK in OA chondrocytes,at least in vitro.At the same time,LIPUS can increase the expression of integrin β1 and p-FAK.The results show that LIPUS may activate an integrin-FAK-MAPK mechanochemical transduction pathway to induce changes in the extracellular matrix of chondrocytes.

BACKGROUND:Stem cel transplantation has gained considerable support recently. It provides new opportunities for treating diabetic neurogenic bladder. OBJECTIVE:To summarize the research progress in bone marrow mesenchymal stem cel s (BMSCs)transplantation in the treatment of diabetic neurogenic bladder. METHODS:The first author retrieved Sciencedirect, PubMed, Embase, Wangfang and CNKI databases, for relevant articles of BMSCs transplantation in the treatment of diabetic neurogenic bladder, published from 2000 to 2016. The key words were“bone marrow mesenchymal stem cel s, diabetic neurogenic bladder, differentiation, transplantation”in Chinese and English, respectively. RESULTS AND CONCLUSION:In patients with diabetic neurogenic bladder, the transplantation of BMSCs may provide safer and longer-lasting outcomes by repairing the damaged bladder and urethra. And it can produce various bioactive substances, which wil have nutritional paracrine effects on the bladder microenvironment, including anti-inflammation, promoting cel proliferation and improving cel survival. On the one hand, the BMSCs have the ability to migrate to the injury site via the blood circulation. On the other hand, BMSCs can produce various growth factors, as wel as the cytokines that can inhibit the inflammatory response. While the current clinical studies are lacking, its efficacy and safety needs further verification.
