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.

Vitamin K deficiency is a common problem in neonates and infants,vitamin K deficiency bleeding can be life threatening.There is still a high incidence of vitamin K deficiency even if the prevention by retrospective analysis a large number of the global data.In recent years,with the increase of premature infants,incidence is higher than before,China is the same trend.There is no recognized prevention and treatment measures,and less related research data.Therefore,to carry out related investigation,to provide the basis for clinical prevention and treatment are an urgent task.

Objective:To analyze data of 5604 cases who received health examination in our hospital ,and understand morbidities of overweight and obesity in these people and their relationship with blood glucose level . Methods :Morning venous blood was taken from the 5604 subjects undergoing health examination to measure blood glucose lev‐el ,and their body weight and height were measured at the same time ,then body mass index (BMI) was calculated and analyzed .Results:Among the 5604 subjects , prevalence rates of overweight and obesity were 42.1% and 13. 3% respectively ,and they were 50% and 16. 4% in men ,and 25. 4% and 6. 8% in women respectively .Among different age groups (except ≥71 years group) , prevalence rate of overweight in men was significantly higher than that of women , P<0.01 all;except ≥61 years subjects , prevalence rate of obesity in men was significantly higher than that of women ,P<0.01 .In overweight group ,risk relative (RR) of impaired fasting blood glucose and dia‐betes mellitus to those of subjects with normal body weight was 2.32 (95% CI 1.91~2.82) and 2.92 (95% CI 2.31~3.70) respectively ;in obesity group , RR of impaired fasting blood glucose and diabetes mellitus to those of subjects with normal body weight was 3.2 (95% CI 2.57~3.99) and 5.17 (95% CI 4.53~5.90) respectively , P=0.001 all . Conclusion:Overweight and obesity have become a common problem among our customer groups .Compared with those with normal body weight ,overweight and obesity greatly increase risk ratio of impaired fasting blood glucose .

Objective To investigate the bacterial distribution and resistance of clinical isolates ,so as to provide basis for the clinical medication .Methods The drug susceptibility testing was performed by Kirby‐Bauer method or automated system .The re‐sults were analyzed by WHONET 5 .6 referring to the breakpoints of CLSI 2013 .Results Of 1 240 clinical iso1ates ,the gram‐posi‐tive cocci and gram‐negative bacteria accounted for 32 .7% and 67 .3% respectively .The top five of isolated strains were Escherichia coli ,Klebsiella spp ,coagulase negative staphylococci ,Staphylococcus aureus ,Streptococcus pneumonia;the first five of isolated spec‐imens constitute followed by sputum ,urine ,blood ,secretions and stool .The average prevalence of methicillin‐resistant strains in S . aureus (MRSA) and coagulase‐negative Staphylococcus (MRCNS)was 17 .1% and 74 .7% ,respectively ;no vancomycin ,teicoplanin or linezolid‐resistant strains were found;no vancomycin‐resistant strains were found in Enterococcus spp;Enterobacteriaceae was still highly susceptible to imipenem and meropenem (> 85% );extended spectrum beta‐lactamases(ESBLs) producing strains ac‐counted for 56 .7% of Escherichia coli ,and accounted for 18 .6% of Klebsiella pneumonia;the drug resistance rates of Pseudomonas aeruginosa to imipenem was 11 .9% .The drug resistance rates of Acinetobacter spp to imipenem was 19 .0% .Conclusion The main infection site of patients in this hospital is respiratory tract and attention should be paid to docimastic sample .The top five clinical i‐solates and drug resistance are roughly the same with the results of Chongqing drug resistance monitoring net .

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.

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.
