OBJECTIVE: To study the effect of taspine hydrochloride (TA/HCl) on skin wound healing in rats and its mechanism. METHODS: Bilateral round wounds were made on the backs of SD rats. The effect of TA/HCl on the skin wound was evaluated through determining closure time and contracting ability of the skin wound, observing histopathological characteristics and measuring contents of hydroxyproline (Hyp) and protein in the wound tissue. RESULTS: The closure time of the skin wounds was significantly shorter in the TA/HCl-treated groups than that in the model group. The percentages of wound contraction were higher in the TA/HCl-treated groups than that in the dimethyl sulfoxide (DMSO) control group of the same group (P<0.05 or P<0.01) on the 3rd to 14th days after wounding. The content of the protein in the wound tissue in the TA/HCl-treated group (2 mg/ml) was higher than that in the model group (P<0.05) on the 3rd to 7th days after wounding, and it arrived at the peak on the 7th day and gradually decreased to the normal level in skin tissue on the 14th to 21st days after wounding. The contents of Hyp in the wound tissues in the TA/HCl-treated groups were higher than that in the model group (P<0.05 or P<0.015) on the 3rd to 21st days after wounding, and they arrived at the peak on the 14th day and at the normal level in skin tissue on the 21st day. Histopathological test results showed that TA/HCl could promote the formation of newly born capillaries in the early period of the wound healing. CONCLUSION: TA/HCl has the ability of promoting skin wound healing in rats, and it can also accelerate the growth of newly born capillaries and raise the production of protein and collagen in wound tissue.

OBJECTIVE:To provide reference for rational use of antibacterial drugs in the clinic. METHODS:In retrospective study,outpatient and emergency antibacterial drugs prescriptions were randomly selected from a hospital during 2013-2014,and then analyzed statistically. DDDs of antibacterial drugs were analyzed by using DDD method. RESULTS:From 2013-2014,the ap-plication rate of antibacterial drugs in the hospital declined substantially from 13.8% to 11.9%,and the rate of irrational use dropped from 2.7% to 1.2%. The application rate of antibacterial drugs was higher in pediatric department,emergency department and urology department;drug cost per capita was higher in infectious department,nephrology department and emergency depart-ment. The application rate of antibacterial drugs in pediatric department decreased greatly in 2014,compared with 2013,maintain-ing about 40%. The application rate of antibacterial drugs in emergency department during Jan.-Sept. in 2014 was lower than corre-sponding period in 2013,and that of the hospital during Jan.-Sept. in 2014 was lower than corresponding period in 2013,but dur-ing Oct.-Dec. in 2014 was slightly higher than corresponding period in 2013. Single type of antibacterial drugs were mainly used in outpatient department,accounting for 91.50% and 90.77% of antibacterial drug prescriptions in 2013 and 2014;two-drug account-ed for 8.44% and 9.11%. The top 3 antibacterial drugs in the list of DDDs during 2013-2014 were roxithromycin,cefuroxime and cefminox. CONCLUSIONS:The use of antibacterial drugs is up to the requirements of Nation Special Rectification Actirity for Clin-ical Application of Antibacterial Drugs in 2013. The prescription comment improve the quality of antibacterial drug prescriptions and rational use index greatly in outpatient department,but the application rate of antibacterial drugs is too high in some depart-ment. There still is irrational use of antibacterial drugs.

Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease. The prevalence of NAFLD is increasing year by year in the world, which seriously threaten the public health. The pathogenesis of NAFLD is complex, and there is no specific treatment for NAFLD. Natural-derived compounds have the characteristics of multi-target and multi-mechanism, which can improve the curative effect and reduce the toxic and side effects by regulating multiple factors of the disease. They are ideal drugs for treating complex diseases and have unique advantages in improving NAFLD. However, low intestinal absorption, poor bioavailability, and single medicine efficiency limit the utilization of many compounds, and further drug development and clinical application are challenging. This paper reviews the research progress of natural-derived compounds in the prevention and treatment of NAFLD in recent years, analyzes the existing problems, and discusses the improvement strategies, so as to provide reference for related research.

China Journal of Orthopaedics and Traumatology 2010;23(6):466-467
OBJECTIVETo explore the clinical efficacy and safety of balloon kyphoplasty for the aged osteoporotic vertebral compression fractures.
METHODSFrom June 2006 to August 2009, balloon kyphoplasty was performed on 26 patients (30 vertebral bodies), who presented painful vertebral compression fractures. They were 10 males and 16 femals, with an average age of 70 years ranging from 59 to 78 years. The operative segments were 4 cases in T11 vertebraes, T12 in 10, L1 in 12, L2 in 3, L4 in 1. The reduction of compressed vertebrae was displayed by X-ray, and the patients were followed up by observation of the visual analog scale and complications.
RESULTSAll cases had rapid, significant and sustained improvements in postoperative pain following balloon kyphoplasty. Visual analog scale was reduced from (8.6 +/- 0.2) to (2.0 +/- 0.3) points. The anterior and midline vertebral body heights in 30 fractured vertebral bodies increased from pre-operative (18.34 +/- 3.25) mm, (14.36 +/- 2.56) mm up to pro-operative (20.51 +/- 1.34) mm, (19.66 +/- 1.28) mm (P < 0.05) respectively. No severe leakage occured.
CONCLUSIONBalloon kyphoplasty in treatment of osteoporotic vertebral compression fractures can restore the height of fractured vertebra, relieve pain and improve the spinal function with satisfactory clinical outcomes.

Objective: To investigate the absorption and transepithelial transport characteristics of scutellarin and scutellarein in the human colonic adenocarcinoma cell (Caco-2) monolayer model. The influence factors on these two compounds' absorption were investigated, such as buffer solution, duration of culture, and inhibitors of multidrug resistance-associated protein 2 (MRP(2)), breast cancer drug resistance protein (BCRP) and P-glycoprotein (P-gp). Methods: By using Caco-2 monolayer as an intestinal epithelial cell model, the transport process was studied from apical (AP) side to basolateral (BL) side or from BL to AP. The two compounds were determined by high-performance liquid chromatography coupled with diode-array-detector detection. Transport parameters and apparent permeability coeffients (P(app)) were calculated. Results: The P(app) values of scutellarin and scutellarein were different in two buffer solutions, respectively. In phosphate buffered saline, scutellarin had no absorption from AP to BL, while its P(app) value was 0.74×10(-6) to 1.58×10(-6) cm/s from BL to AP. The P(app) values of scutellarein were 4.33×10(-6) to 6.79×10(-6) cm/s and 1.32×10(-6) to 2.56×10(-6) cm/s from AP to BL and from BL to AP, respectively. The P(app) value gradually decreased with time. The absorption of scutellarein was better than that of scutellarin. The scutellarin absorption was improved by verapamil, MK-571 and reserpine. The scutellarein absorption was improved by verapamil whereas its excretion was improved by MK-571. Conclusion: Absorption of scutellarin is difficult in Caco-2 monolayer cells, which contributes to its low bioavailability. Scutellarein absorption is better than scutellarin absorption. Scutellarein transepithelial transport is passive diffusion. The inhibitor of P-gp can improve scutellarin and scutellarein transportation. The inhibitors of MRP(2) and BCRP can promote transportation of scutellarin. The inhibitor of MRP(2) can promote efflux of scutellarein. The multidrug resistance-associated protein may be the second reason for low bioavailability of scutellarin.

OBJECTIVE:To provide reference for the formulation of correct antifungal treatment strategy,and to promote stan-dard use of antifungal agent. METHODS:A retrospective survey was conducted for 138 haematologic patients from May 2013 to May 2014 in a third grade class A hospital,of whom all had used antifungal drugs during hospitalization. We collected all patients' information and analyzed it statistically. RESULTS:Of 138 haematologic patients,3 were proven IFD (all were Candida infec-tion),6 were probable IFD,12 were possible IFD,and 117 were undefined IFD. The positive rates of fungi pathogenic detection, fungal smear,G-test,and GM-test were 15.3%,9.4%,6.4% and 23.4% respectively. 6 kinds of antifungal were used,and vori-conazole had the highest frequency,followed by fluconazole,itraconazole,amphotericin B,caspofungin and micafungin. 62.3%patients used only one kind of antifungal,but 15.9% patients used 2 or more kinds of antifungal. The average medication course was 20.5 days(1 day to 125 days). Irrational drug use showed improper drug selection,unreasonable dose,and replacing antifun-gal with insufficient basis. CONCLUSIONS:The antifungal use in haematologic patients in the hospital is consistent with the re-quirements of guidelines,but there are still some issues as insufficient antifurgal drug treatment course to be further standardized.
