1.Fracture healing, delayed union and nonunion
Chinese Journal of Orthopaedic Trauma 2004;0(09):-
Fracture healing consists of four stages: hematoma and inflammation, granulation tissue formation, membranous and endochondral ossification, and remodeling. During these stages, the pathological changes are continuous and overlapping and numerous inflammatory factors and growth factors play a central role in the tissue regeneration and ossification. The fracture will eventually reach primary bone healing or callus healing depending on the stability of fracture site after treatment. The delayed union and nonunion can be assessed according to the treatment time, clinical examination, radiology and biomechanical testing. It is important to understand the differences between hypertropic and atrophic nonunions and the reasons that lead to nonunion. At last, methods to promote fracture healing are summarized and classified into four groups: biological, systemic, mechanical and biophysical ones.
2.Diagnosis of acute compartment syndrome
Chinese Journal of Orthopaedic Trauma 2004;0(10):-
Acute compartment syndrome (ACS) is still an emergent situation in traumatic orthopaedics. Its pathophysiologic mechanism and treatment principles have already been recognized and established widely. The main factors which affect the prognosis are early diagnosis and timing of surgical treatment. This review analyzes the methods of clinical and instrumental diagnosis,rectifies some misunderstandings in clinical evaluation and makes suggestions on appropriate monitoring.

4.Investigation and analysis on premenstrual syndrome among female college students
Chinese Journal of Practical Nursing 2016;32(25):1959-1962
Objective To assess the prevalence and impacts of premenstrual syndrome on female college students,and to provide scientific basis for health education. Methods In the cross-sectional study, a total of 900 female college students from three universities in Jinzhou city were investigated.The data were compiled using the questionnaire of Premenstrual Syndrome Scale by John Bancroft and the general information questionnaire.Results A total of 856 questionnaires were valid among the 900,the validity rate was 95.11%. Premenstrual syndrome was diagnosed in 32.7%(280/856)of all cases,distributed as 22.7%(194/856)mild,7.9%(68/856)moderate and 2.1%(18/856)severe. Binary Logistic regression analysis revealed that premenstrual syndrome was significantly associated with bad sleep condition, animal fat intake, yolk food intake, dysmenorrhea, early age at menarche. Conclusions The results showed that premenstrual syndrome is prevalent among female college students and that life style and nutritional factors may play an important role in this disorder. Therefore,health education and counseling services,as part of the overall health service,should be availed and provided to affected women.

6.Effects of interleukin-1βon MMP-13 expression in rat chondrocytes and its regulation of miR-27b
Tianjin Medical Journal 2015;(8):871-875
Objective To observe the effect of interleukin-1β(IL-1β) on expression of Matrix Metalloproteinases 13 (MMP-13) in rat chondrocytes and its regulation of miR-27b. Methods Chondrocytes were extracted from 7 Wistar male rats. Expression of MMP-13 were examined by Western blot at 0 h, 24 h, 48 h after IL-1βstimulation. Differential miRNAs expression profiles were examined by miRNAs microarray. The most obviously down-regulated miRNAs were confirmed by quantitative Real-time PCR. Targeted regulation relationship between miR-27b and MMP-13 was set up by Luciferase re?porter gene experiments. Results Expression of MMP-13 in rat chondrocytes was increased at a timely dependent manner upon IL-1βstimulation(P<0.05);Microarray revealed 36 miRNAs whose expression changed, among which 6(miR-27b, miR-31, miR-26a, miR-26b, miR-23, miR-204)were especially obvious. Real-time PCR confirmed that miR-27b was the one whose expression level were most down-regulated. Transient co-transfection of miR-27b mimics with luciferase expres?sion plasmids resulted in significant repression of luciferase activity in rat chondrocytes (P < 0.05). Conclusion IL-1βstimulation result in down-regulation of miR-27b and up-regulation of MMP-13 expression. MiR-27b and MMP-13 show targeted regulation relationship.
7.Collagen matrix compared with mitomycin C for treatment of primary open-angle glaucoma with trabeculectomy performed
International Eye Science 2017;17(9):1712-1715
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.
