Chinese Journal of Biochemical Pharmaceutics 2017;37(6):91-93,96
Objective To explore influence of antibiotics and Jiuyi Dan combined with incision-thread-drawing procedure on perianal abscess patients' level of activin A (ACTA) and C-reactive protein (CRP).Methods120 cases of perianal abscess patients in our hospital during March 2015 to December 2016 Coloproctology were selected, they were divided into the experiment group and the control group by random number method.All of patients were taken incision-thread-drawing procedure.Then the experimental group were given nine one antibiotics and Jiuyi Dan, the control group were given antibiotics.The cure rate, 6months after the recurrence rate, average healing time of the wound, and wound edema rate of two groups were observed.Levels of ACTA and CRP expression levels of two groups of patients before and after operation were analyzed.ResultsPatients in the experimental group cure rate was 96.7% higher than that of the control group (P<0.05), the recurrence rate of patients in the experimental group than in the control group, the difference was not statistically significant;the patients in the experimental group the average healing time was (20.67±3.22) d shorter than the average healing time of patients in the control group (29.48±3.15) d, patients in the experimental group wound edema rate of 5% was significantly lower than in the control group 20% (P<0.05);3D ACTA, the expression level of CRP was significantly higher than the preoperative 7 d levels after operation in the two groups (P<0.05);after 7d, the expression level of the two groups of patients with ACTA and CRP were significantly lower than the preoperative level of expression of 7d (P<0.05), experimental group levels of ACTA were significantly lower than the control group, the difference was statistically significant (P<0.05);postoperative 14d patients, ACTA levels of two groups were significantly lower than the levels before operation (P<0.05).ConclusionPerianal abscess can be treated effectively and patients levels of Acta and CRP were obviously dereased by Jiuyi Dan combined with incision-thread-drawing procedure combined, postoperative inflammatory reaction could be importantly alleviated, it was worth clinical promotion.

50% was defined as significant stenosis. Results A 98.7% (778/788) of the coronary artery segments (vessel diameter ≥1.5 mm) could be visualized by 64-slice spiral CT. Compared with catheter angiography in the detection of coronary stenosis, the overall sensitivity, specificity, positive predictive value, negative predictive value and the accuracy of 64-slice CT coronary angiography were 81.9%, 99.0%, 95.9%, 95.1%, and 95.2% respectively. Overall sensitivity would be 91.8% if corrected methodologically. The sensitivity after methodological correction became 91.8%. Conclusion Sixty-four-slice spiral CT examiniation provides a promising non-invasive approach in detecting coronary stenosis with fairly good accuracy, but can not totally replace catheter coronary angiography yet.

7. Research Progress of Nanoparticle Carriers and Their Biological Effects
Chinese Pharmaceutical Journal 2017;52(10):814-818
In recent years, nanoparticle as drug carriers have been widely used in the pharmaceutical field. For some poorly soluble drugs or drugs with strong toxicity and side effects, the design of different nano drug carriers can help achieve improved solubility and targeted therapy. The nano targeted drug delivery system can deliver drug specifically to the target sites and realize controlled release of drugs, thereby increasing the bioavailability and efficacy of drugs and reducing the toxicity and side effects. In this paper, the recent progress in studies on the design of nanoparticles, their biological effects, and their application in the field of medicine are reviewed.

Anthocyanin biosynthesis is one of the thoroughly studied enzymatic pathways in biology, but little is known about the molecular mechanisms of its final stage: the transport of the anthocyanins into the vacuole. A clear picture of the dynamic trafficking of flavonoids is only now beginning to emerge. So far four different models have been proposed to explain the transport of anthocyanins from biosynthetic sites to the central vacuole, and four types of transporters have been found associated with the transport of anthocyanins: glutathione S-transferase, multidrug resistance-associated protein, multidrug and toxic compound extrusion, bilitranslocase-homologue. The functions of these proteins and related genes have also been studied. Although different models have been proposed, cellular and subcellular information is still lacking for reconciliation of different lines of evidence in various anthocyanin sequestration studies. According to the information available, through sequence analysis, gene expression analysis, subcellular positioning and complementation experiments, the function and location of these transporters can be explored, and the anthocyanin transport mechanism can be better understood.
