AIM:To evaluate the effectiveness and safety between trabeculectomy with collagen matrix versus trabeculectomy with mitomycin C(MMC) for patients with primary open-angle glaucoma(POAG).METHODS:In this prospective randomized comparative study from January 2015 to December 2016.Thirty-two eyes presented with POAG were included in this study, 14 eyes treated by trabeculectomy with subconjunctival implant of collagen matrix (study group) and the other 18 eyes treated by trabeculectomy with mitomycin C.Postoperative IOP, the success rate of operation, number of postoperative glaucoma medications and postoperative complications were recorded.Each patient was followed up at least 6mo.RESULTS:The mean postoperative IOP was statistically different between the study group and the control group after 1d (P<0.05), while not statistically different at 1 and 1mo follow-up (P>0.05), and the mean postoperative IOP was statistically different between the two groups (P<0.05) at 3 and 6mo after surgery.There was no significant difference in the success rate of operation between the two groups at 6mo after operation (P>0.05).The IOP decreased at 1d after openations compared with before, kept stable at 1wk to 6mo.IOP of study group was lowen than control.IOP was controlled by glaucoma medications in the study group by 28% compared to control group by 33% at 6mo after operation, but there was no significant difference.There was no significant difference between the study group and the control group in complications (P<0.05).CONCLUSION:Trabeculectomy with collagen matrix implant is comparable to the use of MMC with a similar success rate in open-angle glaucoma and the range in reducing intraocular pressure was significantly higher than that of MMC and it can significantly avoid the occurrence of low IOP postoperatively, transient anterior chamber, conjunctival wound leakage complications has no advantages compared with the use of MMC.

Objective To explore the relationship between restoring Gissane angle and prognosis in calcaneal fracture surgery. Methods Forty patients with single side calcaneal fracture (SandersⅡ-Ⅲ), Gissane angle changed more than 15°and having performed open reduction and internal fixation with steel plate were enrolled. In them, 25 patients (experimental group) recovered Gissane angle in surgery referencing the healthy side with X-rays. Another 15 patients (control group) didn't recover Gissane angle. The ratio of calcaneum height and length was measured at 1 week after surgery. At 6 and 12 months after surgery, the function were valued by Maryland score. Results The ratio of calcaneum height and length in experimental group was significantly higher than that in control group:0.60± 0.04 vs. 0.55±0.05, and there was statistical difference (P<0.05). All the patients were followed up. At 6 and 12 months after surgery, the Maryland score in experimental group were significantly higher than those in control group:(88.9± 5.7) scores vs. (80.5±7.3) scores and (89.5 ±5.5) scores vs. (82.5 ±6.4) scores, and there were statistical differences (P<0.05). Conclusions Restoring Gissane angle is benefitial for prognosis. So in calcaneal fracture surgery, the Gissane angle should be recovered as much as possible referencing the healthy side.

Objective To study the effects of valsartan and triptergium glycosides on the abnormal expression of connective tissue growth factor(CTGF) in rats with diabetic nephropathy. Methods Sixty male SD rats were randomly divided into normal control group,diabetic nephropathy group(DN group),diabetic nephropathy treated with valsartan group(VAL group) and diabetic nephropathy treated with triptergium glycosides group(TG group).Diabetic nephropathy model was established by intraperitoneal injection of streptozotocin(STZ) in DN group,VAL group and TG group.The rats were sacrificed after 2,4,8 and 12 weeks.The body weight,blood glucose,renal function and urinary albumin excretion rate(UAER) were measured,and the expression of CTGFmRNA in kidney was detected by RT-PCR. Results Compared with control group,the levels of blood glucose,blood urea nitrogen,serum creatinine and UAER were significantly increased in DN group(P

Objective To study the relationship between the cancer patients'right to know the true diagnosis and their satisfaction degree with nursing service. Methods We randomly selected 746 patients from the tumor center, the circulation department,the respiration department and surgery department.Questionnaires were designed according to patients'right to know the true diagnosis and the results were analyzed. Results Cancer patients who don't know the true diagnosis wanted to acquire the true information about their diseases but nurses were supposed to keep secret of the actual diagnosis.This contradiction led to the impediment of communication between patients andf nurses compared with other department(P<0.05). Conclusion The right to know their true diagnosis proved to be important for cancer patients in that it could increase the compliance of patients and promote communications so that patients would accept nursing service and the satisfaction degree with nursing service would improved.

Objective:Breast cancer metastasis is a major cause of death. Lymphatic metastasis is one of the two main metastatic ways that is crucial to the metastasis process of breast cancer. To treat breast cancer metastasis, we prepared micelle-based drug carrier for lymphatic delivery. Methods:We used in vivo bioluminescence imaging for real-time dynamic monitoring of the inhibitory effect of polyethylene glycol phospholipid micelle encapsulating vinorelbine on breast cancer metastasis. Results: Compared with the free vinorelbine, vinorelbine-encapsulated micelles (NanoVin) showed a significantly enhanced anti-tumor activity both in primary and met-astatic tumors. Conclusion:Intravenous administration of NanoVin markedly prevented the metastasis of tumor cells through both he-matogenous and lymphatic systems. This study provides a new approach for treatment of metastatic tumors. Bioluminescence imaging is a powerful tool to dynamically monitor tumor metastasis and clinical therapeutic effect of anticancer drugs.
