Objective To evaluate antibacterial activities of Cefoperazone-Sulbactam upon gram negative bacilli,and compare the differences in susceptibility between two different concentrations of Cefoperazone-Sulbactam combination disc.Method A total of 381 strains of commonly occurred gram negative bacilli were found from 2nd Affiliated Hospital of Zhejiang University School of Medicine,Zhejiang Provincial People's Hospital,The Third Hospital of Hangzhou and Hangzhou Hospital of Traditional Chinese Medicine respectively.Susceptibility test was conducted by K-B method using 75 μg/disc Cefoperazone plus with 75 μg/disc Sulbactam(150 disc)and 75 μg/disc Cefoperazone with 30 μg/disc Sulbactam(105 disc),respectively.Meanwhile the minimal inhibitory concentration(MIC)of Cefoperazone-Sulbactam was determined by standard agar dilution.The data were analyzed by using WHONET 5.4 and SPSS.Results Disc diffusion method was carried out to detect the antibacterial activities upon Escherichia coli,Klebsiella pneumonia,Pseudomonas aeruginosa and Acinetobacter baumannii,using 105 disc and 150 disc,respectively.The data indicated that consistency rates between these two different discs were 26.3%,79.2%,83.7%and 33%,respectively.The k-related sample test was performed by using SPSS version 10.0 and shown that the P value was less than 0.05.Upon those organisms mentioned above,the consistency rates between the antibacterial activities of 105 disc and those of agar dilution were 77.8%,89.6%,70.9%and 77%,respectively.When it was going to compare agar dilution vs.150 disc upon the susceptibility of those organisms the consistency rates were 27.3%,79.2%,61.6%and 30%,respectively.Compared with agar dilution,the error rates of those two different concentration discs revealed that the false susceptibility and false intermediate of 105 disc were higher than those of 105 disc.ConclusionsThe results of susceptibility test showed that 105 disc was more close to agar dilution than that of 150 disc.However,the 150 disc used in clinic led to increase in sensitivity of susceptibility test to organisms.

OBJECTIVE: To investigate the factors affecting shoulder joint functions following artificial humeral head replacement. METHODS: A total of 22 patients with complex fracture of proximal humerus, managed by humeral head replacement in Changhai Hospital of The Second Military Medical University from June 2006 to December 2008 were collected, including 12 males and 10 females, with average age of 67 years (52-86 years). During the procedure, soft tissue damage was minimized, the bone of the tuberosity was reserved as much as possible, appropriate matching size of humerus head prosthesis was selected, and early staging functional rehabilitation was performed. Neer's scoring system was used to evaluate the treatment results after replacement. RESULTS: The 22 patients were followed up for 10-30 months, mean 22.6 months. The shoulder joint functions of 14 cases were recovered more quickly through early post-operative staging rehabilitation, No shoulder joint unstable and stiff occurred. The shoulder joint functions of 8 cases were recovered slowly as they complained pain and did not perform early physical therapy after surgery, shoulder joint of 2 cases presented little unstable and 1 case presented stiff. Only 4 cases of all complained occasionally slight shoulder pain, but could continue daily work. The mean movement ranges of shoulder were as follow: mean flexion for 96°(80°-103°), mean extension for 38° (32°-45°), mean abduction for 86°(80°-110°), mean adduction for 31°(30°-35°), mean external rotation for 32°(30°-37°) and internal rotation for 42° (10°-75°). No vasculardamage, nerve damage, lessening prosthesis or prosthesis dislocation was found in all cases. Based on Neer's scoring system, 5 cases were rated as excellent, 11 as good and 4 as fair, with excellent rate of 82% and case satisfaction rate of 87%. CONCLUSION: In order to recover maximally the shoulder joint functions for post-artificial humeral head replacement, we must try our best to avoid soft tissue damage, reserve the bone of the tuberosity, select appropriate humerus head prosthesis, perform early post-operative staging rehabilitation, as well as maintain a normal retroversion of the prosthesis.

OBJECTIVETo investigate the exerted force in different phases of the female menstrual cycle, as well as the changes in estrogen (E2), osteocalcin (OCN), receptor activator of nuclear factor-kappa B ligand (RANKL), and osteoprotegerin (OPG) levels in the gingival crevicular fluid (GCF) during orthodontic tooth movement, to provide a theoretical basis for the selection of the best opportunity for efficient tooth movement.

METHODSTwelve women (aged 18 years to 28 years) with extracted first premolars had been selected. Six women in the group were randomly selected as the menstrual period group, whereas the remaining six were assigned to the ovulation period group. Right canines were retracted with 1.5 N NiTi close coil spring. GCF samples were collected prior to the force exertion experiments at 0 (T0), 15 (T1), 30 (T2), and 45 d (T3). The levels of E2, OCN, OPG and RANKL in GCF were measured by chemiluminescence and enzymelinked immunosorbent assay.

RESULTSThe E2 and OCN levels were significantly higher in the ovulation period group than in the menstrual period group (P < 0.05). No significant differences were found in RANKL and OPG levels between the two groups (P > 0.05). Finally, no significant difference was found in RANKL/OPG ratio between the two groups (P > 0.05).

CONCLUSIONExerted force on teeth during the menstrual period may promote rapid tooth movement.

The research on intracellular trafficking of adenovirus has been described mainly through observations of subgroup C adenoviruses in transformed cell lines. The basic elements of the trafficking pathway include binding to receptors at the cell surface, internalization by endocytosis, lysis of the endosomal membrane, escape to the cytosol, intracellular trafficking along microtubules, nuclear pore docking, and viral genome translocation into the nucleus. More than 80% of the adenovirus genome is delivered to the nucleus in a highly efficient manner in approximately 1 h. However, exceptions to this trafficking pattern have been noted, including: variations based on target cell type, cell physiology, and adenovirus serotype. This review summarizes mechanism of adenovirus infection pathway and intracellular trafficking, providinging a foundation for the development of clinical adenoviral vector.
