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.

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 investigate the effect of all-trans retinoic acid (ATRA) on transforming growth factor β1 (TGF-β1)/Notch signaling pathway in injured podocytes induced by adriamycin (ADR) in vitro.Methods Podocytes cultured in vitro were randomly divided into normal group,model group,ATRA treatment control group,12-hour ATRA intervention group and 24-hour ATRA intervention group.Morphological changes were observed by using light microscope.The expressions of TGF-β1,podocin,Notch 1,Jagged 1 mRNA were evaluated through real-time polymerase chain reaction (RT-PCR) and the corresponding proteins were detected by using Western blot.Results (1) No obvious changes between normal group and ATRA treatment control group were revealed as the plump podocytes and distinct outline were found in light microscope,while podocytes in model group showed disordered arrangement,fuzzy boundary,atrophy,hypertrophy and increased cellular debris.Of note,the podocytes in 12-hour ATRA intervention group and 24-hour ATRA intervention group almost returned to normal.(2) In contrast with those in model group,the amounts of TGF-β1,Notchl,Jaggedl mRNA levels decreased in 12-hour ATRA intervention group (1.34 ±0.43 vs.4.16 ±0.31,1.67 ±0.2 vs.4.21 ±0.92,2.08 ±0.27 vs.5.14 ±0.63,q =23.83,11.45,19.67,all P ＜0.05) and 24-hour ATRA intervention group (1.22 ± 0.16 vs.4.16 ± 0.31,1.73 ± 0.53 vs.4.21 ± 0.92,2.08 ± 0.29 vs.5.14 ± 0.63,q =24.85,11.18,19.67,all P ＜ 0.05),and the differences were significant;similar trend was detected in the protein levels (1.04 ± 0.03 vs.4.31 ± 0.10,1.06 ± 0.04 vs.4.47 ± 0.24,1.07 ± 0.04 vs.4.20 ± 0.16,1.06 ±0.03 vs.4.31 ±0.10,1.07 ±0.03 vs.4.47 ±0.24,1.09 ±0.03 vs.4.20 ±0.16,q =163.50,69.61,90.36,162.50,69.40,89.78,all P ＜ 0.05),and the differences were significant;whereas the level of podocin mRNA (1.13 ±0.05 vs.0.40 ± 0.06,1.16 ± 0.03 vs.0.40 ± 0.06,q =36.50,38.00,all P ＜ 0.05) and protein (1.01 ± 0.01 vs.0.44 ±0.01,1.02 ±0.01 vs.0.44 ±0.01,q =180.25,183.41,all P ＜0.05) increased,and the differences were sig nificant.(3) The expressions of Notch1,Jagged1 mRNA were positively correlated with TGF-β1 mRNA (r =0.84,1.00,all P ＜ 0.05),but negatively correlated with podocin mRNA (r =-0.95,-0.94,all P ＜ 0.05) in model group.Conclusions ATRA might alleviate podocyte injury through cutting the expressions of TGF-β1,Notch1,Jagged1 and raising the expression of podocin in injured podocytes induced by ADR.

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.

To investigate the main factors influencing the quality of life and the relationship between quality of life and basic syndromes of traditional Chinese medicine (TCM) in patients with post hepatitic cirrhosis.

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.

Results:The nursing students in the experimental group of operating examination results was better than the control group(P<0.05).The application of case introduction and assessment approach of the team can develop good teamwork spirit(86.30%), communication skills(71.85%), consciousness of active learning(81.11%), clinical decision-making(75.93%), and clinical adaptive-ability(87.04%). Conclusion:The model of case introduction and assessment approach of the team can improve the clinical comprehensive ability partly.

AIM: To investigate the feasibility of establishment for chronic graft-versus-host disease (cGVHD) model in rats after allo-bone marrow transplantation (allo-BMT), in order to provide premise conditions for further studying the immuno-regulation role of mesenchymal stem cell (MSC) on GVHD after allo-BMT. METHODS: This experiment was finished in Laboratory of Pathology and Pathophysiology in Sun Yat-sen University from April to September 2006.①Six-week-old male Fischer344 rats (RT1Al) were used as donors while six-week-old female Waster (RT1Au) rats were used as recipients.②Recipient rats were given water supplemented with gentamycin (320 mg/L) and erythromycin (250 mg/L) three days before BMT. On the day of transplantation, recipient rats received 8.0 Gy (60Co ?, 0.7 Gy/min) total body irradiation. Within 6 hours following the irradiation, recipient rats in BMT group were transplanted with 0.8?108 cells via tail vein injection, while rats in control group only received the same volume injection of phosphate buffer. Each group included 10 animals. Evaluation of common living status was monitored including daily diet, activity, stool and urine, fur and body mass. Shaved skin, liver and intestine tissues were also analyzed histologically. RESULTS: ①All rats in the control group died within 17 days following the irradiation and most of them died on day 11 or 12 post-transplantation, while BMT group had higher survival rate, in addition to three rats died on days 12, 16, 18 respectively, whereas others were all alive through 60 days expectation period.②Rats in the BMT group had no clear symptoms of acute GVHD, such as rapid weight loss and severe diarrhea, however, the weight growth in rats of the BMT group was quite slow. Furthermore, 1 month following BMT, depilation phenomenon was evident in the head and back of recipients, and then extended to abdominal part and extremity with the increase of time. Two months following BMT, skin follicular dropout and slight dermal mononuclear infiltration were found. Hepatic disease was characterized by portal tract lymphocyte infiltration, fibrous thickening and sclerosis of the bile duct wall. Small bowel specimens showed clear inflammatory cell infiltration (neutrophils, acidophils, macrophages) within lamina propria. CONCLUSION: ①The cGVHD model can be established through allo-BMT from F344 to Wistar rats.②The typical histological signs of cGVHD are evident in skin, liver and intestine tissues, among which hepatic sign is the most dominant including portal tract and bile duct mononuclear infiltration followed by fibrous thickening and sclerosis of the bile duct wall.
