Objective To investigate the incidence trends,clinical features and prognosis of ischemic colitis (IC) in China,and improve the level of diagnosis and treatment of IC.Methods China National Knowledge Infrastructure and VIP Chinese Science and Technology Periodical Database were searched.The ending date of search was May 15,2014.Results A total of 324 references were found,which were published from 1982 to 2013.There were 9202 cases reported,3973 cases of males and 5229 cases of females,with the male/female ratio of 1 ∶ 1.32 and mean age of (63.6±7.8)years.The amount of references and cases reported began to rise after 2002.Estimated ratio of cumulative incidence was higher in the north than in other areas of China (x2 =1097.95,P=0.000).The most common IC accompanying diseases were hypertension,heart diseases,diabetes,hyperlipidemia and constipation.There were statistically significant differences in the accompanying diseases between different regions and different times.Drugs,enteroscopy,surgery and low blood volume might be the precipitating factors.Patients commonly complained of abdominal pain,diarrhea/ desiring to defecate and hematochezia.Computed tomography was feasible in detecting lesions.Colonoscopy was the main method for diagnosis.The lesions were most common located in the left half colon including sigmoid colon,descending colon and splenic flexure,with typically in a segmental manner.Pan-colon involvement or rectum involvement rarely occurred.Type of transient lesion was the predominant subtype,which was generally managed non-operatively with good prognosis.Different from the type of transient lesion,pathological changes in gangrenous type were located in the right half colon including hepatic flexure of transverse colon,ascending colon and ileocecal junction.Gangrenous type required prompt surgical intervention but the mortality was much higher.Conclusions Incidence of CI has been increasing year by year.Patients who complain of abdominal pain,diarrhea/desiring to defecate and hematochezia should be considered as IC,particularly in the elderly women and patients with cardiovascular disease.Diseased regions are mainly located in sigmoid colon,descending colon and splenic flexure.Transient colitis is the predominant subtype,which have good prognosis.

Objective:To observe the clinic effect of wild apricot in Xinjiang Uighur nationality on fatty liver.Methods:With a western medicine group as the control group,the treatment courses of both two groups were 12 weeks.The trial group was given wild apricot decoction orally,the control group was given vitamin B,C and Glucurolactone tables.Results:Wild apricot exerted a significant effect in lowering the fat and treating the fatty liver without any toxic and side-effects.Conclusion:Wild apricot in Xinjiang Uighur nationality served as a vital treatment to fatty livers,which was worth being further promoted in the clinical therapy.

Objective To investigate clinical effect of surgical repair and reconstruction of traumatic floating shoulder injuries (FSI). Methods Sixteen patients with FSI were treated with open re-duction and reconstructive internal plate fixation. Of all, one patient was with transverse clavicle fracture, six with oblique clavicle fracture and nine with comminuted clavicle fracture. There was one patient with type Ⅰ scapula fracture, three with type Ⅱ, four with type Ⅲ, six with type Ⅳ and two with type Ⅴ. The combined injuries included rib fracture plus hemopneumothorax in six patients, traumatic moist lung in two, craniocerebral injuries in two, hepatic and splenic rupture in two and brachial plexus damage in one. The average time from primary injury to operation was seven days (3-21 days). Results Fifteen out of 16 patients were followed up for 6-28 months (average 11 months). All patients obtained bone u-nion, without infection, loosening or breakage of internal fixation. According to Herscvici evaluation standard of function, the shoulder joint outcome was rated as excellent in 11 patients, good in three and fair in one, with excellence rate of 93%. Conclusion The surgical repair and reconstruction of FSI can, to a greatest extent, recover the anatomical structure and stability around the shoulder joint and shorten the immobilization period of joint, which is beneficial to functional restoration of the joint and de-crease of occurrence of complications.

Objective To investigate the effect of prosthetic replacement for senior patients with unstable intertrochanteric fractures of the femur.Methods Fifty-three senior patients with comminuted intertrochanteric fracture of the femur were subjected to total hip arthroplasty (n =23) and bipolar artificial femoral head replacement (n =30).Uncemented long-stem prostheses were used in 50 patients and cemented long-stem prostheses in 3.Time interval between admission and surgery was 3-13 days (mean 6 days).Results The total hip arthroplasty had the operation time for mean 90 minutes (range,80-110 minutes) and blood loss for mean 350 ml (range,260-410 ml).While the hemiarthroplasty had operation time for mean 65 minutes (range,50-90 minutes) and blood loss for mean 230 ml (range,180-290 ml).Fifty-one patients were available to mean 49.6-month follow-up (range,13-65 months).Four patients presented with frequent hip pain at a tolerable level after hemiarthroplasty and the symptom was relieved after oral non-steroidal anti-inflammatory drug therapy.One patient with postoperative infection was cured by timely debridement.Seven patients were died of heart and brain disorders in 5 years,with no relation to surgical complications.The period for fracture healing was mean 10 months,with excellence rate of 96％ for hip function but with no acetabulum abrasion,implant loosening or submersion.Conclusion Early prosthetic replacement is an effective treatment for unstable intertrochanteric femoral fractures in the elderly.

Objective To investigate the antimicrobial resistance of clinical strains of K lebsiella spp .isolated from 15 hospitals in China CHINET during 2012 .Methods Kirby-Bauer method and automatic microbiology analysis system were employed to study the antimicrobial resistance . WHONET 5 .6 software was applied for data analysis according to Clinical and Laboratory Standards Institute (CLSI) 2012 breakpoints .Results A total of 9 621 clinical K lebsiella isolates were analyzed ,including 8 772 strains of K . pneumoniae and 804 strains of K . oxytoca . About 54 .9% (5 285/9 621) of the K lebsiella strains were isolated from sputum ,and 16 .3% (1 564/9 621) were isolated from pediatric patients .Antimicrobial susceptibility testing showed that about 8 .9% ,10 .8% and 12 .9% of the strains were resistant to imipenem ,meropenem and ertapenem ,respectively .About 14 .1% and 17 .0% of the strains were resistant to piperacillin-tazobactam and cefoperazone-sulbactam , respectively . Carbapenem-resistant K lebsiella strains were identified from all the 15 hospitals ,including 945 strains of K .pneumoniae and 45 strains of K .oxytoca ,which were resistant to either imipenem ,meropenem or ertapenem .Conclusions The Klebsiella isolates collected from 15 hospitals in China during 2012 are relatively sensitive to carbapenems ,cefoperazone-sulbactam and piperacillin-tazobactam .The prevalence of carbapenem-resistant strains is still increasing in China ,about 10 .3% in 2012 ,and relatively higher in Eastern China .More efforts should be made to control the superbug .
