ABSTRACT
Objective To investigate the clinical effect of Sodium Hyaluronate Injection and psychological intervention in the treatment of knee osteoarthritis. Methods The control group of patients with knee osteoarthritis treated treatment group in the conventional research on Sodium Hyaluronate Injection, Sodium Hyaluronate Injection treatment combined with psychological intervention, record the two groups before and after treatment of knee joint function changes. Results There was no significant difference between the two groups in the knee function before treatment. After the corresponding treatment, the Lysholm scores of the two groups were significantly higher than before, and the knee joint function improvement in the study group was better (P<0.05). Conclusion The application of sodium hyaluronate and psychological intervention in the treatment of osteoarthritis of knee joint can significantly improve the efficacy of patients, and is conducive to the protection of their physical and mental health, quality of life.
ABSTRACT
Objective To establish a method to quantify the residual cross-linker vinyl sulfone and its hydration product 1 ,4-Thioxane-1 ,1-Dioxide.Methods The polysaccharide was precipitated by ethanol,however vinyl sulfone and its hydration product were soluble,and can be analyzed by direct injection.The analysis was carried on Agilent DB-wax capillary column (30m ×0.53 mm,1.0 μm).The flame ionization detector (FID)and flame photometric detector (FPD)were used to detect samples and the efficiency were compared. Results The linear range of vinyl sulfone and its hydration product were separately 0.5 ~20μg/mL and 2~100μg/mL detected by FID.The Limit of Quantity (LOQ)were 0.8μg/mL and 2.3μg/mL, respctively.The Limit of Detection (LOD)were 2.6μg/mLand 7.6μg/mL,respectively,and the average recoveries (n=9)of them were 104.3%and 92.4%,respectively.Conclusion FID could meet the needs of the test,and this method is simple and accurate with high sensitivity and good repeatability,which can be used for quality control of trace vinyl sulfone and its hydration products 1 ,4-Thioxane-1 ,1-Dioxide in cross-linked sodium hyaluronate injection.
ABSTRACT
AIM: To compare the effect of treating cataract by sodium hyaluronate injection and lens - loop nucleus extraction of small incision cataract excision and explore more suitable method to promote the use of surgery in primary hospital. METHODS: All 146 cataract patients ( 166 eyes ) were allocated to two groups in random: the control group 78 patients ( 84 eyes ) received conventional lens loop for extracapsular cataract extraction;the experiment group 68 patients (82 eyes) underwent nucleus extraction in small incision with sodium hyaluronate injection for extracapsular cataract extraction. Postoperative visual acuity and intraoperative and postoperative complications were compared between two groups. RESULTS: Incidence of posterior capsule rupture difference was statistically significant (P 0. 05 ) in postoperative visual acuity, astigmatism degree and postoperative complications compared with those of pre-operation. CONCLUSION: Compared with the lens loop nucleus extraction, sodium hyaluronate injection for extracapsular cataract extraction can effectively protect the posterior lens capsule and can be promoted in small incision cataract surgery.
