Antimicrobial peptides, a cluster of small peptides secreted by the majority of creatures, have been demonstrated with activity against a wide range of microorganisms including bacteria, protozoa, yeast, fungi, viruses and even tumor cells. These peptides have some features such as broad spectrum , high effi-cacy and stability, little drug resistance. A lack of new antibiotics combined with emerging multi-drug resis-tance issues demands that new antimicrobial strategies be explored for treating these infections. It has been proposed that the antimicrobial peptides might form the foundation for a new class of clinically useful an-timicrobials. We review the advantages of these molecules in construction features and bioactivity, with the focus on the mechanism and clinical applications.

Objective To evaluate the association of islet autoantibodies [ glutamic acid decarboxylase antibody(GADA),protein tyrosine phosphatase antibody(IA-2A)and insulin autoantibodies(IAA)1 with HLA- DQ genotypes in the first-degree relatives of autoimmune type 1 diabetes mellitus.Methods This was a cross- sectional and case-control study.Three hundred and fifty-one first-degree relatives with normal glucose tolerance of patients with type 1 diabetes mellitus and 376 healthy controls were recruited and measured for GADA,IA-2A and IAA by radioligand assay,and 156 first-degree relatives of patients with autoimmune type 1 diabetes mellitus and 278 controls were typed for genetic polymorphisms of HLA-DQ with PCR sequencing-based typing method.Results (1)DQA1*03,DQBI*0303,*0401 alleles and DQA1 * 03-DQBI * 0303,DQA1 * 05-DQBI * 0201,DQA1 * 03-DQBI * 0401 haplotypes were significantly increased in the first-degree relatives of autoimmune type 1 diabetes mellitus(P

Objective To explore the status of postpartum mental health among pregnant women so as to take relevant measures to keep their mental health.Methods SCL-90 was used to measure the mental status of 146 pregnant women,and DXC-Ⅲ type was used to transforme data.Results Among 146 pregnant women,except for the factor of somatization,other factors were significantly different from norm( P ＜0.01 ).The average score of somatization,depression,hostility and paranoid in less than 30 years old group was ( 1.42 ± 0.37 ),( 1.32 ± 0.45 ),( 1.40 ± 0.60),( 1.24 ± 0.45 ) respectively which was higher than ( 1.26 ± 0.28 ),( 1.19 ±0.25 ),( 1.20 ± 0.34 ),( 1.12 ± 0.20 ) in more than 30 years old group,and the difference was statistically significant( t =2.73,2.03,2.27,2.01;P ＜ 0.01 ). The score of somatization,depression,anxiety,mental disorder in less than 30 days after delivery was significantly higher than that in more than 30 days after delivery (P ＜ 0.05).Conclusions Pregnant women after delivery have hostility mental and the younger they are,the more negative emotions they experience.So,society and family should pay attention to it and give more support.

OBJECTIVETo evaluate the sperm quality of college students in Chengdu area.

METHODSA computer assisted sperm analysis (CASA) was made of the sperm concentration, grade A sperm, grade B sperm, sperm viability rate and movement parameters (VCL, VAP, VSL, LIN, STR) of 549 volunteers from 14 colleges in Chengdu area. The volunteers were divided into normal and abnormal groups according to the criteria (sperm concentration > or = 20 x 10(6)/ml, grade A and B sperm > or = 50% or grade A sperm > or = 25%). The results were compared with the data reported in China.

RESULTSAmong the 549 volunteers, the sperm concentration was (50.90 +/- 27.31) x 10(6)/ml, grade A and B sperm was (42.21 +/- 15.38)%, grade A sperm was (29.48 +/- 13.71)%, and the sperm viability rate was (56.40 +/- 14.77)%. The volunteers with normal sperm accounted for 62.84% (345/549) in contrast with abnormal (37.16%, 204/549). Among the 204 volunteers with abnormal sperms, there were 187 (90.67%) with abnormal motility, 39 (19.21%) with abnormal concentration, 22 (10.78%) with both abnormal concentration and abnormal motility. There were no volunteers without sperm. Among the 345 volunteers with normal sperm, the VCL, VAP and VSL were above 25 microns/s, and the VCL, VAP, VSL, LIN and STR were significantly higher than those of the abnormal group (P < 0.01). Moreover, the sperm concentration and the sperm viability rate in 549 volunteers, including 345 volunteers with normal sperm, were lower than the data reported in China.

CONCLUSIONSDue attention should be paid to the sperm quality of the college students in Chengdu area, whose sperm concentration and sperm viability rate have a tendency to decrease.

Objective To evaluate the clinical effect in the treatment of the young patients(≤45 years old) with acute myocardial infarction(AMI)underwent emergent percutaneous transluminal coronary angioplasty(PTCA) combined with Lipo-PGE_1.Methods 39 patients with AMI(paroxysm within 12 hours),were underwent emergent PTCA(coronary stem performed in some patients),including 18 cases which were treated combined with Lipo-PGE_1 in the mean time.And the clinical efficacy and the results of short-period follow-up were recorded.Results The in- farctive vasculars were re-open in 37 patients(23 cares were routinely placed translunrinal srents),and the successful rate was 94.9 %.Those who also used Lipo-PGE_1 were re-open in 17 patients.The successful rate was 94.4 %,their ST segments on EKG 30 minutes after operations reduced significantly than that of patients who did not use Lipo- PGE_1,their cardial functions were also improved significantly 24 hours after operations and no side effects on blood pressure and heart rate were observed.Conclusion The emergent PTCA combined with Lipo-PGE_1 for acute my- ocardial infarction can protect the cardial function and show a better early therapy effect.

OBJECTIVESTo compare the outcomes after liver resection for a single small hepatocellular carcinoma (HCC) (≤ 5 cm) between non-cirrhotic patients and cirrhotic patients, and to explore the influence of liver cirrhosis on recurrence and overall survival after liver resection in patients with a single small HCC.

METHODSA consecutive series of 256 patients with a single small HCC undergoing liver resection from April 2001 to October 2009 was retrospectively reviewed. Among the 256 patients, 227 patients were male, and 29 were female. The medium age was 49 years (ranged, 14 - 79 years); 224 (87.5%) patients were positive for hepatitis B surface antigen, 241 (94.1%) patients were with preoperative liver function of Child-Pugh grade A. The entire cohort were divided into non-cirrhosis group (n = 44) and cirrhosis group (n = 212). Univariate analysis and then multivariate analysis were performed to determine the prognostic factors of recurrence and overall survival after liver resection for all patients.

RESULTSThe 1-, 3-, 5-year recurrence-free survival rates after liver resection were 93.0%, 85.3%, and 68.5%, respectively, in non-cirrhosis group, while 81.1%, 58.6%, and 45.0%, respectively, in cirrhosis group. The 1-, 3-, 5-year overall survival rates after liver resection were 100%, 92.5%, and 92.5%, respectively, in non-cirrhosis group, while 93.8%, 78.7%, and 67.8%, respectively, in cirrhosis group. Both the recurrence-free survival and overall survival of non-cirrhosis group were significantly better than those of cirrhosis group (χ(2) = 8.756, P = 0.003; χ(2) = 8.603, P = 0.003). Cirrhosis, absence of tumor capsule, presence of microvascular invasion and moderate/poor tumor differentiation were the independent adverse prognostic factors for recurrence-free survival and overall survival in patients with a single small HCC after liver resection.

CONCLUSIONSCirrhosis is an important adverse prognostic factor for long-term survival in patients with a single small HCC after liver resection. Liver resection resulted in much worse survival for cirrhotic patients compared to non-cirrhotic patients.

OBJECTIVETo study the commodity specification and grade standard of Pseudostellaria Radix, for standardizing market order and achieving industrialization, standardization and modernization of Pseudostellariae Radix.

METHODThe different areas and grade medicinal materials of Pseudostellariae Radix were respectively measured in quantitative characteristics of appearance, and the present grade classification of Pseudostellaria Radix was scientifically verified by the content of polysaccharide. Then the determination data were evaluated by spss correlation analysis, principal component analysis and cluster analysis. So combining with the actual production, the commodity grade standard of Pseudostellariae Radix was formulated.

RESULTCorrelation analysis indicated that the present grade classification of Pseudostellaria Radix was reasonable, and the more the grade of Pseudostellariae Radix was high, the more the content of polysaccharide was high. Meanwhile, length as a classification index was not suitable for the commodity grade standard of Pseudostellariae Radix. Using principal component analysis and cluster analysis, combining actual production, the thickest diameter, weight of single root tuber and the number of 50 g root tuber were filtrated and the grade was divided into 5 ranks: big, mid- dle, small selected goods, big ungraded goods and small ungraded goods.

CONCLUSIONthe commodity specification and grade standard of Pseudostellariae Radix that mainly included the thickest diameter, weight of single root tuber and the number of 50 g root tuber was formulated, the standard was divided into 5 grade. Each grade was not only consistent with the present situation of medicinal materials market, it could also reflected the intrinsic quality of Pseudostellariae Radix. In conclusion, the standard could be used as a classifica- tion basis to the commodity specification and grade.
