Group A β-hemolytic streptococcus (GAS),namely Streptococcus pyogenes,is one of the most im-portant human pathogen.GAS can cause skin and mucous membrane superficial infectious diseases,life -threatening invasive disease,toxin -mediated diseases and immune -related diseases.Antibiotic is an effective mean to control GAS infection.The β-lactam antibiotics remain the first -choice treatment for GAS infection and the macrolides are often recommended as a replacement therapy for β-lactam antibiotics allergic patients or a means to blocking GAS exotoxin product.But with the widespread use of macrolides autibiotics,macrolide -resistant GAS spread in the world. This paper will elaborate the situation of macrolide -resistant clones.

Objective To explore the mechanism of therapeutic action of needle knife “regulating sinews and treating bones” on knee osteoarthritis (KOA) by observing the effect of needle knife intervention on KOA rabbit behaviors, mechanical characteristics of patellar ligament (PL), and expressions of interleukin-4 (IL-4), matrix metalloproteinase-3 (MMP-3) and aggrecan in knee cartilages.Methods Forty New Zealand rabbits were randomly allocated to blank, model, needle knife and electroacupuncture groups, 10 rabbits each. A rabbit model of KOA was made by the modified Videman method of immobilization in extension position. After model making, the needle knife and electroacupuncture groups received needle knife and electroacupuncture treatments, respectively. A behavioral assessment was made using the modified Lequesne MG knee grade evaluation method in every group after model making and treatment. The samples were taken after treatment. PL tension, stress relaxation and creep state were tested using a Bose Electro Force 3300 protracted test machine. Cartilage cell IL-4 expression was examined by ELISA. MMP-3 mRNA and aggrecan mRNA expressions were detected by real-time PCR.Results After model making, there was a statistically significant difference in the Lequesne MG score between the model and blank groups (P<0.01); there was no statistically significant difference in the Lequesne MG score between the needle knife or electroacupuncture group and the model group (P>0.05). There was a statistically significant post-treatment difference in the Lequesne MG score between the needle knife or electroacupuncture group and the model group (P<0.01,P<0.05) and between the needle knife and electroacupuncture groups (P<0.05). There were statistically significant post-treatment differences in PL maximum stress, maximum displacement, elastic modulus, stress relaxation rate and creep rate between the model and blank groups (P<0.01,P<0.05). There were statistically significant post-treatment post-treatment differences in PL maximum stress, maximum displacement, elastic modulus, stress relaxation rate and creep rate between the needle knife and model groups (P<0.01,P<0.05). There was a statistically significant post-treatment difference in elastic modulus between the electroacupuncture and model groups (P<0.01). The IL-4 content and aggrecan mRNA expression decreased significantly and MMP-3 mRNA expression increased significantly in the model group after model making and there were statistically significant differences compared with the blank group (P<0.01,P<0.05). After treatment, the IL-4 content increased significantly in the needle knife and electroacupuncture groups compared with the model group (P<0.01,P<0.05) and aggrecan mRNA expression tended to increase in the two groups. The regulation of aggrecan mRNA and MMP-3 mRNA expressions was better in the needle knife group than in the electroacupuncture groups, but there was no statistically significant difference compared with the model group (P>0.05).Conclusion The mechanism of action of needle knife treatment on KOA may be that it improves ligament mechanical characteristics, regulates intra-articular stress environment, and modulates aggrecan mRNA and MMP-3 mRNA expressions and inhibits cartilage degeneration through IL-4 mechanical signal pathway, to produce the therapeutic effect of “regulating sinews and treating bones”.

Objective To investigate the relationships among cerebellar mutism (CM), relapsed medulloblastoma (MB) and the primary tumor location.MethodsA retrospective analysis was conducted in 114 children over 3 years old with MB from November 2011 to April 2015.ResultsThe median onset age was 84.7 months (36.4 to 184.7 months) in 114 children with MB (77 boys and 37 girls), of whom there were 48 cases of recurrence. There were twenty two cases of CM and the overall incidence of CM was 19.3% (22/114). The incidence of CM was 19.7% (13/66) in non-recurrent cases and 18.8% (9/48) in recur-rent cases, and there was no signiifcant difference between two groups (P=0.899). The incidence of CM was 17.6% (9/51) in cas-es with primary tumor in the fourth ventricle, 7.1% (1/14) in cases with primary tumor in the cerebellar vermis, 21.4% (3/14) in cases with primary tumor in both fourth ventricle and cerebellar vermis, 45.5% (5/11) in cases with primary tumor in fourth ven-tricle and other parts of the brain, and 50.0% (4/8) in cases with primary tumor in cerebellar vermis and other parts of the brain. No CM incidence was observed in cases with primary tumor in central nerve system except for the fourth ventricle and cerebellar vermis. The incidence of CM between the cases with fourth ventricle/cerebellar vermis involvement and those without fourth ventricle/ cerebellar vermis involvement had signiifcant difference (P=0.039). ConclusionsThere is no relationship between CM and relapsed MB. Children with MB whose primary tumor is located in the fourth ventricle and/or the cerebellar vermis is susceptible to CM.

To ensure the stability of chemistry components and the convenience of operation, ultrasound method was chosen to study in this investigation. As the total common peaks area in chromatograms was set to be evaluation index, the influence on the technology caused by extraction time, ethanol concentration and liquid-to-solid ratio was studied by using single factor methodology, and the extraction technology of Paeoniae Radix Alba was optimized by using response surface methodology. The results showed that the extracting results were most affected by ethanol concentration; liquid-to-solid ratio came the second and extraction time thirdly. The optimum ultrasonic-assisted extraction conditions were as follow: the ultrasonic extraction time was 20.06 min, the ethanol concentration in solvent was 72.04%, and the liquid-to-solid ratio was 53.38 mL · g(-1), the predicted value of total common peaks area was 2.1608 x 10(8). Under the extraction conditions after optimization, the total common peaks area was 2.1422 x 10(8), and the relative deviation between the measured and predicted value was 0.86%, so the optimized extraction technology for Paeoniae Radix Alba is suitable and feasible. Besides, for the purpose of extracting more sufficiently and completely, the optimized extraction technology had more advantages than the extraction method recorded in the monogragh of Paeoniae Radix Alba in Chinese Pharmacopoeia, which will come true the assessment and utilization comprehensively.

OBJECTIVETo study measurement methods of acromioclavicular and coracoclavicular ligament injuries,its therapeutic effects and complications during internal fixation operation for the treatment of fresh acromioclavicular joint dislocations of Tossy type III.

METHODSFrom July 2003 to May 2012,127 patients with acromioclavicular joint dislocations of Tossy type III were treated with wire fixation from coracoid process to clavicle or hook-plate fixation. The patients were divided into group A (63 cases) and group B (64 cases) according to whether acromioclavicular ligament and coracoclavicular ligament were repaired or not. In group A (ligaments repaired), there were 39 males and 24 females with an average age of (33.25 +/- 8.46) years old (ranged from 17 to 59 years). And in group B (no ligaments repaired), there were 41 males and 23 females with an average age of (34.10 +/- 7.19) years (ranged from 19 to 57 years). The operation times, intraoperative blood loss, postoperative infections, internal fixation failure, recurrence and other complications, together with therapeutic effects were compared between two groups.

RESULTSThe outcome was analyzed according to Karlsson standard. In group A, 54 patients got an excellent result and 9 good according to Karlsson standard;the average operative time was (55.90 +/- 26.56) min; the average intraoperative bleeding amount was (99.80 +/- 50.30) ml; 1 patient had wire broken without re-dislocation at 16 weeks after operation, 3 patients got wound fat liquefaction and recovered after treatment, 1 patient had pain after shoulder joint motion and pain disappeared after implants were taken out. In group B, 52 patients got an excellent result and 12 good according to Karlsson standard; the average operative time was (49.50 +/- 23.14) min; the average intraoperative bleeding amount was (87.30 +/- 46.41) ml; 2 patients got wound fat liquefaction, and 2 patients had pain after shoulder joint motion. All the patients were followed up, and the duration ranged from 9 to 16 months. All internal steel-wire or hook plate were taken out during 4 to 9 months without acromioclavicular joint re dislocation. There were no significant difference in the average operative time, the average intraoperative blood less, complication recurrence rates of fixation failure, wound fat liquefaction, postoperative infection, acromioclavicular joint re-dislocation, and therapeutic effects between two groups.

CONCLUSIONBoth wire and clavicular hook plate fixation, performed for fresh acromioclavicular joint dislocation with Tossy type III, are simple, effective, less invasive method with less blood loss. In addition, the treatment without ligaments repaired could not increase incidence of complications.
