Objective:To study the in vitro and in vivo transdermal enhancement of one kind of arginine oligomer-chitosan ( CS-R9). Methods: In vitro mouse skin as the barrier, Franz diffusion cells were used to study the transdermal property of tinidazole ( TNZ) solution in vitro enhanced by CS-R9 using TNZ solution as the negative control and TNZ solution with Azone as the positive control. The rats were randomly divided into three groups, TNZ solution group ( the negative group) , TNZ solution with Azone group (the positive group) and TNZ solution with CS-R9 group. At the predetermined time intervals, 0. 5 ml blood was withdrawn from the rats and TNZ concentration was detected by HPLC to evaluate the enhancement of CS-R9 on TNZ in vivo. Results:Compared with the negative group, CS-R9 had significant enhancement on TNZ trandermal penetration in vitro(P <0.05), and showed no significant difference with Azone (P>0. 05). The in vivo results showed CS-R9 exhibited similar transdermal enhancement on TNZ as Azone at the same concentration (P>0. 05), and CS-R9 had sustalned-release property. Conclusion: CS-R9 has promising transdermal en-hancement on TNZ, which is valuable to be studied further.

Type 2 diabetes is a complex metabolic disease, accompanied by insulin resistance and elevated blood glucose. As the disease progresses, hyperglucagonemia will occur. Glucagon has a significant effect on glucose increase and energy expenditure. In recent years, several glucagon receptor (GCGR) antagonists were developed. They lowered blood glucose in clinical studies, along with side effects, such as increased blood lipids and elevated liver transaminase. In order to solve these problems, glucagon like peptide 1 receptor (GLP-1R)/GCGR co-agonists were developed, which not only lower blood glucose, but also reduce weight and promote lipolysis. In this review, we will focus on the biological effects of glucagon, the treatments of GCGR antagonists, and GLP-1R/GCGR co-agonists on type 2 diabetes.

AIM:To discuss Daidzein intravitreal injection whether has protective and recovery effects on acute nerve damages.
METHODS:After the crush models of acute optic nerve were set up, 72 males SD rats were divided into 4 groups randomly as common group without surgery, FBS negative control group, Daidzein treatment group ( 10μmol/L, 100μmol/L, 1000μmol/L ) and positive control group using rats nerve growth factor ( mNGF, 100ng/mL ). Three days after interference, all experimental animals were executed. HE staining was used to evaluate morphologic change of the retina, immunohisochemical staining and western-blot tests for identifying and quantifying the distinct expression of Caspase-3 and GAP-43 among the groups.
RESULTS: Compared with the normal group and negative control group, retinal morphology of different concentrations of each Daidzein treatment group and positive control group was more complete, the expression of Caspase-3 protein was relatively lower, the expression of GAP-43 protein was relatively higher, the differences have statistically significance (P<0. 05).CONCLUSION: Daizein injection in the vitreous cavity has the capacity of protection and restoration in rat's acute nerve damages.

BACKGROUND:Acute poisoning is frequently encountered at emergency department. This study was to investigate the epidemiology and characteristics of patients with acute poisoning who were treated at the Emergency Center, Fujian Provincial Hospital, China. METHODS:We retrospectively analyzed the gender, age, causes of poisoning, types of poisons, poisoning route, emergency diagnoses, outcomes, and prognoses of these patients. RESULTS:Altogether 2867 patients with acute poisoning were treated from January 2004 to December 2009. The ratio of male to female was 1:1.04, and their average age was 33.8 years. Of the 2867 patients, 76.39％ were between 18 and 40 years old. The incidence of acute poisoning was as high as 11.33％ in January each year. The incidence of poisoning was in a descending order:alcohol poisoning (54.55％), medication poisoning (25.95％), pesticide poisoning (5.65％), and drug poisoning (4.88％). Most (56.44％) of the patients with drug poisoning were under 25 years and their mean age was significantly lower than that of patients with medication poisoning or alcohol poisoning (P < 0.01). Approximately 69.54％ of the patients were followed up after emergency treatment, 30.39％ were hospitalized, and four patients died. CONCLUSIONS:Acute poisoning is largely alcohol poisoning and medication poisoning in a city. The emergency green channel "pre-hospital emergency care-emergency department-hospital treatment"can significantly improve the survival rate of patients with acute poisoning.

Ten percent of mutants increased the potency of daptomycin by streptomycin-resistance method, including the mutant LC-54, which could produce daptomycin 81. 2 mg/L, which was 39% higher than that of the beginning strain by flask fermentation.

OBJECTIVETo evaluate the clinical effectiveness of Yiqi Huoxue Tongyang Xiezhuo Recipe (YHTXR, capable of supplementing qi, activating blood, warming yang, and discharge turbidity) in treating coronary atherosclerotic heart disease (CAHD). and chronic heart failure (CHF) with carotid plaque patients, and to explore new ways of Chinese medicine (CM).

METHODSTotally 69 CAHD-CHF patients of qi deficiency phlegm stasis syndrome (QDPSS) with carotid plaque were recruited in this study using parallel cohort method. They were assigned to the treatment group (35 cases) and the control group (34 cases). Patients in the control group received routine treatment of Western medicine, while those in the treatment group were additionally treated with YHTXR (twice daily). The therapeutic course for all was three months. Cardiac function levels, echocardiography, carotid plaque, blood lipids and safety indicators were observed before and after treatment.

RESULTSAfter treatment the improvement of cardiac function levels was better in the treatment group than in the control group (P < 0.05). Decreased LDL-C levels were higher in the treatment group than in the control group (P < 0.01). There was statistical difference in left ventricular ejection fraction (LVEF), carotid intima-media thickness (IMT), LDL-C, TC, TG in the treatment group between before and after treatment (P < 0.05). LDL-C and TG also decreased in the control group after treatment (P <0.05). There was no significant difference in the left ventricular ejection fraction, carotid IMT, or TC in the control group between before and after treatment (P > 0.05). There was no significant difference in stroke volume, left ventricular end-diastolic diameter, the area of carotid artery plaque, or HDL-C in the two groups between before and after treatment (P > 0.05).

CONCLUSIONSYHTXR could effectively improve cardiac functions of CAHD-CHF patients of QDPSS with carotid plaque, reduce blood lipids and IMT. It had no significant adverse reactions for elderly patients in short term.
