OBJECTIVETo observe therapeutic effects of locking titanium plate for the treatment of comminuted proximal humeral fracture in elderly.

METHODSFrom June 2011 to May 2013, 72 elderly patients with comminuted proximal humeral- fractures were divided into locking titanium plate group and anatomical plate group, 36 cases in each group. In locking titanium plate group, there were 16 males and 20 females aged from 60 to 79 years old with an average of (69.55±5.62) years old; 10 cases were type Neer II, 18 were type Neer III and 8 cases were type Neer IV in accordance with Neer classification; treated with locking titanium plate. In anatomical plate group, there were 15 males and 21 females aged from 60 to 81 years old with an average of (69.76±5.70) years old; 9 cases were type Neer II, 20 were type Neer III and 7 cases were type Neer IV; and treated with anatomical plate. Clinical effects, preoperative and postoperative Neer scoring, operative time, bone healing time and incidence of complications between two groups were compared.

RESULTSAll patients were followed up from 1 to 3 years with an average of 15 months. The excellent and good rate of locking titanium plate group (91.7%) was significantly higher than anatomical plate group (75.0%). Postoperative Neer score of two groups were improved obviously, but locking titanium plate group (92.51±7.85) was higher than anatomical plate group (83.64±8.56); there was no significant differences between two groups in operative time (P>0.05); bone healing time in locking titanium plate was (18.6±3.4) weeks, and shorter than anatomical plate group (24.3±3.9) weeks; incidence of complications in locking titanium plate was (5.6%) shorter than anatomical plate group (22.2%), and had obviously differences between two groups.

CONCLUSIONLocking titanium plate for the treatment of comminuted proximal humeral fracture in elderly plays an important role in good rate, bone healing time and Neer score. It has advantages of early rehabilitation exercise, less shoulder pain, rapid recovery of shoulder joint, less complications, safe and effective, and be worthy of clinical application, especially for senile osteoporosis patients.

The inflammatory bowel diseases (IBDs), consisting of ulcerative colitis (UC) and Crohn's disease (CD), are characterized by idiopathic, chronic inflammation of the gastrointestinal tract. The overall incidence of IBDs is constantly increasing in eastern countries. In comparison with the data from western nations, in China, the incidence of male IBDs is relatively higher, the onset age is older. The severity of most cases is mild to moderate. The occurrence of fistula and peri-anal involvement are rare. Although significant improvements of IBDs therapy have been achieved in recent years, there are still over 30% UC and 70% CD cases need at least one surgery throughout their life span. Here we review the literatures published in recent years about the surgical management of IBDs.

Objective To study the prevalence of mental disorders among the Chinese youths aged 15-34 years,in rural areas and to identify risk factors related to suicide.Methods A consecutive sampling strategy was used for suicidal cases in 16 randomly selected counties in Hunan,Liaoning,and Shandong provinces.Between 2005 and 2008,a total of 392 suicide cases were recruited with 416 community controls at the same age range,selected from the same areas one family member together with one close friend of each suicidal case were interviewed,using the psychological autopsy (PA) method.The same method with structured instruments was performed on the two informants for each control in the same community.SCID was used for the diagnosis of mental disease.Results 48.0％ of the suicides were diagnosed as having at least one mental disorder episode,in comparison with only 3.8％ among the controls.It was found that mental disorder was the most important risk factor for the Chinese young suicide cases in the rural areas.Conclusion As seen in the Western countries,mental disorder had also been the number one correlate on suicidal cases in China,with the difference as other social and psychological factors might have played relatively more important roles in China.

Myeloid differentiation factor MyD88 is a critical adaptor molecule that integrates and transduces intracellular signals in inducing the differentiation of dendritic cells (DCs).The domain regions within MyD88 was searched,it could potentially affect the function of dendritic cells and found that MyD88 aa155-171 motif not only regulate the activity of transcription factor NF-?B, but also control the production of cytokines and expression of costimulatory molecules. Indeed, aa155-171 motif deleted type MyD88 (MyD88155-171) transfected RAW264.7 cells exhibited the reduced NF-?B and AP-1 activity and interrupted the expression of CD86 and B7H1. Meanwhile, lower level expression of cytokines such as IL-12,IFN-? were also observed by means of cytokine array in MyD88-/-DC trasfected with MyD88155-171 as compared to the MyD88 transfected cells. Thus, aa155-171 motif inside MyD88 could affect the expression of costimulatory molecules, production of cytokines and transduction of Toll like receptor signal pathway, suggesting that this motif may play an important role in regulating responses of innate immune system.

Objective To investigate the antimicrobial resistance of Enterobacteriaceae isolated from patients of first class hospitals in China in 2012.Methods All the clinical isolates of Enterobacteriaceae were collected and the susceptibility tests of the isolates were performed by 557 first class hospitals around China from 1st Jan.2012 to 31st Dec.2012.The susceptibilities of isolates to antimicrobial agents were determined by using CLSI (2010) guideline and the susceptibility data were processed with Whonet 5.6 software.Results A total of 372052 clinical isolates were collected.Among all the strains Escherichia coli ( 161211starins, 43.3%) outnumbered the other bacteria, followed by Klebsiella pneu-moniae (112600 strains, 30.3%), Enterobacter clacaer (31887strains, 8.6 %).The most effective antimicrobials were carbapenems.The re-sistant rates of Escherichia coli to imipenem and meropenem were both be-low 12.5%, and the rates in other Enterobacteriaceae were below 10%.Besides this, piperacillin/tazobactam, cefoperazone/sulbactam and ami-kacin demonstrated good antibacterial activity against Enterobacteriaceae in vitro.Overall, little difference was observed in the resistant rates of Enterobacteriaceae isolated from first class hospi-tals in different parts of China.Conclusion Enterobacteriaceae from firs class hospital were of different degree resis-tance to various antimicrobial agents.Carbapenems remained very high activity against Enterobacteriaceae,but the car-bapenem resistance strains has appeared and the issue should be attracted attention.

Objective To investigate the antimicrobial resistance of nonfermenting gram-negative bacteria in China in 2012.Methods All the clinical isolates of nonfermenting gram -negative bacteria were collected from 557 tertiary hospitals from 1st January 2012 to 31st December 2012 in China.The antimicrobial susceptibilities of the isolates were de-termined by using various methods such as broth microdilution, disk diffusion, or E-test which according to CLSI 2012 guideline.The sus-ceptibility data were processed with WHONET 5.6 software.Results A total of 198334 nonfermenting gram-negative bacteria susceptibility data were obtained.Among all the isolates, the top 3 isolated nonfermenting gram-negative strains were Pseudomonas aeruginosa ( 80964 strains, 40.8%) , followed by Acinetobacter baumannii(67368 strains, 34.0%) , and Stenotrophomonas maltophilia ( 17520 strains, 8.8%).Against Pseudomonas aeruginosa, polymyxin B, tobramycin, ceftazidime, ciprofloxacin, levofloxacin, cefepime, gentamicin and cefoperazone/sulbactam ( CSL) were the only agents to which >70%of isolates were susceptible.No antibiotics except polymyxin B ( 96.9%) , minocycline ( 61.4%) , amikacin (58.7%), CSL (54.3%) and tobramycin (51.3%) were active more than 50% against Acinetobacter baumannii.Susceptibility rates of carbapenem against Acinetobacter baumannii were around 49%, about 9 percentage points higher than 2011 results.There are some differences among the monitoring results from various districts in China.The suscep-tibilities of Pseudomonas aeruginosa and Acinetobacter baumannii to the tested antimicrobial agents in Central China were generally low, whereas the antimicrobial susceptibilities of Acinetobacter baumannii from North China were genera-lly high.Conclusion The multidrug resistance of nonfermenting gram -negative bacteria, especially Acinetobacter baumannii, has become a worldwide problem.There are some differences among the susceptibilities of isolates from various districts.Polymyxin B has the most effective in vitro antimicrobial activity against Pseudomonas aeruginosa and Acinetobacter baumannii isolates, the emerging resistant isolates should cause enough attention.Further surveillance needed to be strengthened to prevent the further development and spread of resistant bacteria.
