OBJECTIVETo investigate the role of autophagy in acute lung injury (ALI) caused by multiple trauma in rats via pretreat with 3-methyladenine (3-MA).

METHODSForty-five Sprague-Dawley male rats, with age of 4 months and body weight of 250-300 g,were randomly divided into three groups. In the sham group, the rats received sphenotresia only;in the control group, the rats were made model of femur shaft fracture combined with brain injury, and treated with physiological saline by abdominal cavity at 1 hour before making model; in the 3-MA group, the rats were made model of femur shaft fracture combined with brain injury,and treated with 3-MA of 10 mg/kg by abdominal cavity at 1 hour before making model. Histologic changes and the concentration of related inflammatory factors in the damaged lung tissue were examined at 48 h after opteration, at the same time, the effect of 3-MA on the expression of LC-3 II and Beclin-1 was examined through reverse transcriptase polymerase chain reaction technique (RT-PCR).

RESULTSCompared with sham group, LC-3 II and Beclin-1 level in control group at 48 h after operation were obviously increased (P < 0.01). Compared with control group, LC-3 II and Beclin-1 level in 3-MA group at 48 h after operation were obviously decreased (P < 0.01). Compared with sham group, the level of proinflammatory cytokines (TNF-α and IL-6) in control group obviously enhanced (P < 0.01). Compared with control group, above items in 3-MA group was obviously lower (P < 0.01). Compared with control group,the histopathological damage of lung in 3-MA group obviously reduced (P < 0.01).

CONCLUSIONAutophagy can aggravate the acute lung injury caused by fracture of shaft of femur combined with brain injuries,but 3-MA can reduce tissue damage by inhibiting the autophagy and inflammatory response.

Objective To explore the way to compile a global military medical literature collection and perspectives for its research.Methods The names of military medical research institutions and their trends of development were summa-rized via semantic analysis.The collection of retrieval words for military medical research institutions( then the collection) was constructed based on expert consultation.The names of military medical research institutions were collect-ed with manual screening after retrieval withthe collection.The literature collection of military medical research institu-tions was completed with coordinated retrieved of their papers and other publications.Results According to different needs of information analysis, the literature collection of military medical research institutions could be analyzed in terms of their size, types of development, and academic authority.Conclusion Based onthe collection, the military medical research institutions collected in this article included institutions that used to be neglected during the course of information tracking of military medicine.Three kinds of institutions should be paid more attention to.The institutions were the ones with a large number of papers and citations, the ones whose papers increased or decreased dramatically, as well as the ones whose research directions were the priority fields of Chinese PLA.

Glycyrrhiza uralensis Fisch. ex DC is widely used in traditional Chinese medicine (TCM). Among its various active components, glycyrrhizic acid is believed to be the marker component. Squalene synthase (SQS) and beta-amyrin synthase (beta-AS) are key enzymes in the biosynthetic pathway of glycyrrhizic acid in G uralensis. To reveal the effects of co-expression of SQS1 and beta-AS genes on this pathway, 7 yeast expression vectors harboring different SQS1 variants and beta-AS were constructed and expressed in Saccharomyces cerevisiae as fusion proteins. TLC and GC-MS results showed that co-expression of SQS1 and beta-AS enhanced the accumulation of beta-amyrin. The effects of SQS12 were more obvious than the other two SQS1 variants. This study is significant for further investigations concerned with exploring the biosynthesis of glycyrrhizic acid in vitro and strengthening the efficacy of G. uralensis by means of increasing the content of glycyrrhizic acid.

Professional assessment in Chinese Higher Education has made great progress in three stages: the sporadic practice, trial and promotion. The authors present several comments on the characteristics and the professional assessment standards of clinical pharmacy in China, and focus on the scientific system of professional assessment.

Objective:To investigate the clinic effect of r-MHT and hematoma aspiration on the traumatic intracerebral hematoma.Methods:89 cases with traumatic intracerebral hematoma were given hematoma aspiration,47 of them were given r-MHT and hematoma aspiration,the clinic effect on the 1st,7th,14th day after treatment were evaluated by NIHSS,the hematoma volume before treatment on the 1st,7th,14th day after treatment were counted by Dotian formula.Results:The effective rate of treatment group was 93.6％,which was significantly higher than that of the control group (P＜0.05).The NIHSS score of treatment group was significantly higher than that of the control group(P＜0.05) on the 1 st day,1st,2nd week after treatment (P＜0.05).Conclusion:r-MHT and hematoma aspiration couldn effectively reduce the brain damage,improve the patient's neurological fumction in treating traumatic intracerebral hematoma.

OBJECTIVETo investigate the relationship between the second to the fourth digit ratio (2D:4D) and body mass index (BMI) in infertile men of the Han ethnic group in Ningxia.

METHODSUsing anthropometry, we calculated the mean ratio of 2D:4D and BMI of 197 infertile men and 148 normal healthy male controls, followed by analysis of their relationship.

RESULTSThe BMI was correlated positively with the 2D:4D ratio of the left hand in the infertile men (P < 0.05) and in the patients with a higher 2D:4D ratio of the left hand (P < 0.05), but negatively with the 2D:4D ratio of the righ/left (Dr-1) (left: P < 0.01; Dr-l: P < 0.05). The mean 2D: 4D ratio and BMI were both lower in the normal control than in the infertile men, with statistically significant differences in BMI (P < 0.05) and the 2D:4D ratio of the left hand (P < 0.05).

CONCLUSIONThere is a correlation between the 2D:4D ratio and BMI in infertile men.
