Objective To study the application of contact oxidization and hydrolysis acidifying technology in hospital wastewater treatment. Methods Hydrolysis combined with chlorine dioxide disinfection was used in the engineering of treatment. Results Even if CODCr was 300 mg/L, BOD5 was 150 mg/L, SS was 300 mg/L, pH was 6-9 and large intestine bacteria number was 50 000/L, the wastewater quality met the requirement of related standard after treated with the present method. Conclusion The present technology was efficient, practical and economical.

Compared with hip replacement, internal fixation in the treatment of the elderly femoral neck fracture, especially the application of cannulated screws, is minimally invasive, easy to operate and economical. In recent years, it becomes the research focus in the field of orthopedic clinical research. However, configuration of cannulated screws is still controversial. Most clinicians believe that three cannulated screws being placed in parallel in an inverted triangle configuration is better than that in a triangular configuration in biomechanics and clinical effect. Nonparallel strong oblique nailing technique allows the screws to share more weight to reduce postoperative complications, so that it is more suitable for elderly patients with osteoporosis. However, the related complications of internal fixation such as nonunion, femoral neck shortening and other problems are still the focus of domestic and foreign scholars. Issues about how to control the indication of internal fixation surgery, understand related factors of the complications, and prevent complications are required to be further explored.

Objective To compare the clinical outcomes between oblique and non-oblique fixation with cannulated screws for femoral neck fractures in the elderly patients.Methods Totally 189 patients of over 65 years old were treated for femoral neck fracture from June 2007 to October 2013 at our department.Oblique fixation with cannulated screws was used in 130 cases.They were 43 males aud 87 females with an average age of 77.8 ± 7.5 years.According to Garden classification,40 cases were of Garden types Ⅰ and Ⅱ (undisplaced fractures),and 90 of Garden types Ⅲ and Ⅳ (displaced fractures).Of them 26 were Pauwells type Ⅲ.Non-oblique fixation with cannulated screws was conducted in 59 cases.They were 24 males and 35 females with an average age of 75.5 ± 8.2 years.According to Garden classification,12 cases were of Garden types Ⅰ and Ⅱ (undisplaced fractures),and 47 of Garden types Ⅲ and Ⅳ (displaced fractures).Of them,15 were Pauwells type Ⅲ.The fracture union,postoperative complications,rate of reoperation and Harris scores at the last follow-up were compared between the 2 groups.Results All the 189 patients were followed up for 10 to 38 months (average,17.4 months).The oblique fixation led to a union rate of 99.2％ (129/130),a fixation failure rate of 3.1％ (4/130) and a femoral head necrosis rate of 2.3％ (3/130),which were not significantly different from those resulted from the non-oblique fixation [98.3％ (58/59),10.2％ (6/59) and 5.1％ (3/59) respectively] (P ＞ 0.05).However,the rate of femoral neck shortening [35.4％ (46/130)] and the reoperation rate [3.1％ (4/130)] in the oblique fixation group were significantly lower than those in the non-oblique fixation group [50.8％ (30/59) and 15.3％ (9/59) respectively] (P ＜ 0.05).The mean Harris hip score at the last follow-up for the oblique fixation(75.7 ± 14.3) was significantly higher than that for the non-oblique fixation (70.8 ± 16.7) (P ＜ 0.05).Conclusion As oblique cannulated screwing can reduce the rates of femoral neck shortening and reoperation to some extent,it may be a better fixation choice than the non-oblique cannulated screwing for femoral neck fracture in elderly patients.

OBJECTIVE: To develop a unified and discriminative method for the characterization of different diclofenac sodium extended release tablets. METHODS The flow-through cell method was employed to investigate the dissolution characteristics of all the samples at different flow rates and in different dissolution media. The dissolution data under the finally selected dissolution condition was also used to analyze the similarity of dissolution curves and statistical significance of Weibull parameters. RESULTS: The dissolution behaviors of the samples were not significantly influenced by flow rates in the selected range. The dissolution at a flow rate of 4 mL · min-1 and in hydrochloric acid (0.1 mol · L-1) for one hour followed by water for another seven hours was satisfactory to discriminate the samples, which was demonstrated by f2 and Weibull parameters analysis. CONCLUSION: This method can be used for dissolution tests of diclofenac sodium extended release tablet samples from the manufacturers in this study with meanings in guiding both comprehensive investigation on the dissolution of diclofenac sodium extended release tablets and quality improvement of generic drugs.

Objective To investigate the effect of povidone iodine irrigation combined with levofloxacin eye drops on the inflammatory indexes, NO and antioxidant indices in serum and tear fluid of patients with diabetic cataract.Methods 50 cases of pati ents with diabetic cataract and admitted into the hospital during January 2013 to January 2015 were selected as the research objects all of whom received cataract surgery.According to the randomized double blind method, the patients were divided into two groups with 20 cases in each group.The control group received levofloxacin eye drops intervention before surgery while the observation group were treated withpovidone iodine irrigation, based on the control group.The inflammatory indexes (IL-2, sIL-2R, IL-6), NO, antioxidant indexes (TAC, SOD, CAT) and condition of postoperative infection were compared between the two groups before and after irrigation.ResuIts In the observation group, the sIL-2R, IL-6 and NO levels in serum and tear fluid after irrigation were significantly lower than those in the control group while IL-2, TAC, SOD and CAT were significantly higher than those in the control group.The differences were statistically significant (P<0.05).The postoperative infection rate of the observation group was 0.0% which was significantly lower than 16.0% of the control group.The difference was statistically significant ( P<0.05 ) .ConcIusion Povidone iodine irrigation combined with levofloxacin eye drops can significantly reduce the inflammatory reactions in patients with diabetic cataract and improve their antioxidant level.
