In response to problems from the development of multi-drug-resistant pathogenic bacteria,it is urgent to find new antimicrobials.Antimicrobial peptides(AMPs) are a kind of ideal new antimicrobials with the advantages including their potential for broad-spectrum activity,rapid bactericidal activity and low propensity for resistance development,and have a bright future.Alpha-helical antimicrobial peptides are a main kind of AMPs.The following features was reviewed and elucidated including the structure and activity relationship(SAR) from different aspects including the degree of helicity,hydrophobic moment,hydrophobicity,net positive charges and so on,and the application of SAR on the molecular design and improvement of AMPs.

OBJECTIVETo evaluate the preliminary curative effect of interspinous injections for the diagnosis and treatment of back pain caused by lumbar kissing spine (Baastrup's disease) under fluoroscopically guiding.
METHODSFrom November 2011 to March 2013,17 patients with back pain caused by Baastrup's disease were treated with fluoroscopically-guided interspinous injections, including 7 males and 10 females with an average age of 49.6 years old ranging from 40 to 71 years old; the duration of the disease ranged from 2 to 5 years with a mean of 3.7 years. The visual analogue scale (VAS) and the lumbar segments range of motion (ROM) was analyzed at pre-operation, 2 days, 3 months and final followed-up after operation, the effects were evaluated with modified Macnab standard.
RESULTSAll patients were follow-up from 6 to 10 months with an average of 7.6 months. The pre-operative VAS was 6.41 +/- 0.94, the postoperative VAS at different time points improved significantly comparing with pre-operation,and the differences were statistically significant (P < 0.01). There was no significant difference in VAS at different time points after operation (P > 0.05). The ROM of operated segment and adjacent segment was (4.88 +/- 0.86) degrees and (6.82 +/- 0.73) degrees respectively at pre-operation. The postoperative operated segment ROM at different time points improved significantly comparing with pre-operation, and the differences were statistically significant (P < 0.05). Compared with pre-operation, there was no significant difference in adjacent segment ROM at different time points after operation (P > 0.05). According to modified Macnab, the result was excellent in 6 cases, good in 7 cases, fair in 3 cases and poor in 1 case.
CONCLUSIONFluoroscopically-guided interspinous injections is an effective method for the diagnosis and treatment of Baastrup's disease. The method has advantages of simple operation, minimal invasion and safety, satisfactory short-term and medium-term therapeutic effect; it can also effectively lessen the pain of lumbar and back.

Objective To explore the application value of endoscopic thyroidectomy via breast approach without transection anterior cervical muscle group .Methods The clinical data of 130 patients which treated by thyroidectomy without transection ante‐rior cervical muscle group were analyzed ,retrospectively .There were 68 cases treated by endoscopic thyroidectomy via breast ap‐proach and 62 cases treated by conventional thyroidectomy .Results 68 patients underwent endoscopic thyroidectomy ,the mean time of operation was(127 .66 ± 29 .56)min ,which was longer than that in conventional group (89 .06 ± 24 .25)min(P<0 .01) ,but blood loss was significantly less in endoscopy group than that in conventional group(19 .13 ± 7 .37)mL vs .(50 .17 ± 29 .28)mL . (P<0 .01) .The patients treated by endoscopic thyroidectomy with neck pain induration were less than that in conventional group (1 case vs .7 case) ,P<0 .01 ,and the nerve dysfunction were (4 case vs .3 case) ,P>0 .05 ,the nerve dysfunction had no significant difference .Conclusion Endoscopic thyroidectomy via breast approach without transection anterior cervical muscle group has less blood loss ,lower neck pain induration rate ,hidden incisions and excellent cosmetic benefits .The method is safe and feasible .

Objective To assess the diagnostic value of MRCP before LC.Methods 944 cases with chronic calculous cholecystitis underwent MRCP before LC from June 2004 to June 2007 in our department.incidence rate of cholecvstolithiasis together with common bile duct stones and incidence rate of anatomic abnormity of bile duct were collected.Results The incidence rate of cholecvstolithiasis together with common bile duct stones were 8.1%(77/944),and the oecurence ofACBDS were 1.2%(11/944).The incidence rate of anatomic abnormity of bile duct were 3.7%(35/944).ConclusionMRCP can not only offer a excellent diagnostic value of ACBDS and anatomic abnormity of bile duct,but also reduce the occurrence of CBDS remainder and iatrogenic bile duct iniuries.

Objective To compare the effects of fluvastatin and valsartan on the inflammatory cytokines in the early stage of type 2 diabetic nephropathy and their protective effects on to diabetic nephropathy. Methods Ninety patients with early stage of type 2 diabetic nephropathy were divided into three groups, 30 patients receiving routine hypoglycemic agents (DN1) as control,30 patients receiving routine hypoglycemic agents plus valsartan (DN2) and the other 30 receiving routine hypoglycemic agents plus fluvastatin (DN3). Blood glucose, blood lipid,serum creatinine and C reactive protein(CRP),24-hour urine protein,urinary albumin excretion rate (UAER) and several inflammatory cytokine were measured before and after treatment. Results ( 1 ) No significant difference of the levels of serum CRP,TGF-β1,IL-6,TNF-α, IL-18 at the baseline were observedamong these three groups.In the DN2 group,after treatment,IL.6 was([15.99±2.87]ng/L and[17.64±2. 131 ,P <0. 05) ,TGF-β1 was ( [33.54 ±10. 69] μg/L and [40. 11 ± 12. 08] μg/L,t = -2. 921 ,P <0. 01 ),IL-18 was ( [139.65±66. 37] ng/L and [158.74±74. 20]ng/L,t = -2.053,P <0. 05),CRP was ( [5. 12±3. 54] mg/L and [6. 08 ±3. 39] mg/L, t = - 2. 072, P < 0. 05 ) after and before treatment, respectively. All abovemented indices significantly decreased after treatment. In the DN3 group, IL-6 was ( [15. 39 ±2. 77] ng/L ng/L,t = -3. 651 ,P <0. 01 ) ,TGF-β1 was ( [31.19 ±10. 48] μg/L and [37. 11± 11.76] μg/L,t = -2. 963,P<0.01),IL-18 was ([141.54 ±66.65] ng/L and [158.01±73.23] ng/L,t = -2. 182,P <0.05),CRP respectively. All abovemented indices significantly decreased after treatment No significant difference was observed on inflamaory factors after treatment between the DN2 and DN3 group ( P > 0. 05). (2) In the subgroup that there was no difference in blood pressure between before and after treatment in both the DN2 and DN3 group,in the DN3 group,UAER was ([63. 1 ±31.7] μg/min and[82.9±40.0] μg/min,t = -2. 145,P <0. 05) ,24 h total urokinase protein was ( [0. 14 ±0. 11] g/24 h and [0. 18±O. 15] g/24 h, t = - 2. 438, P <0. 05 ), microalbuminuria/urine creatinine was ( [ALb/Cr] [114. 7±68. 1] mg/g and [162.0±83.8] mg/g,t = - 2. 399, P < 0. 05 ) after and before treatment. All abovemention indices significantly decreased after treatment. In the DN3 group, UAER was ( [65.5 ±32. 6]μg/min and [83.5 ±42. 1]μg/min,t = - 2. 131, P <0. 05 ),24 h total urine protein was ( [0. 14 ±0. 11] g/24 h and [0. 18±0. 15] g/24 h, t = - 2. 438, P < 0. 05 ),0. 05 ) after and before treatment. All abovemention indices significantly decreased after treatment. No significant difference was observed after treatment between the DN2 and ON3 group ( P > 0. 05 ). Conclusion Both valsartan and fluvastatin are able to protect the renal function of patients with type 2 diabetic nephropathy by decreasing the levels of urine proteins and correlated serum inflammatory cytokines.
