Danshen is one of the traditional Chinese herbal medicines and nas a long history or being used clinically in the treatment of cardiovascular and cerebrovascular conditions such as coronary heart disease and angina pectoris. Tanshinone IIA is a derivative of phenanthrene-quinone isolated from Danshen. It has been reported to be the major bioactive compound of Danshen and has diverse biological effects. Recent studies demonstrated that tanshinone IIA had neuroprotective effects on experimental ischemic stroke through its antiinflammatory, anti-oxidant, anti-apoptosis effects and its inhibitory effect on excitatory amino acid toxicity. In this review, we summarized all the recent progresses on the protective effect of tanshinone IIA on cerebral ischemic stroke. Hopefully, this article will throw some light on further study and application of tanshinone IIA.

OBJECTIVETo explore clinical effects of internal fixation in treating displaced clavicle fracture combined with coracoid process.

METHODSFrom January 2005 to July 2012, 9 patients with displaced clavicle fracture combined with coracoid process were treated by internal fixation. Among them, there were 6 males and 3 females with an average age of 40.1 (ranged from 20 to 57) years old. According to Eyres classification: 3 cases were type II B, 1 case was type II A, 3 cases were type III B, and 2 cases were type V A. All patients had history of injury, and diagnosed as coracoid fracture X-ray and CT before operation. Herscovici criteria was used to evaluate function of shoulders joint after operation.

RESULTSSeven of 9 patients were followed up from 6 to 18 (averaged 11) months. The incisions were healed at stage I, coracoid process obtained bony healing, and reduction of acromioclavicular joint well. According to Herscovici criteria, 6 patients got excellent results and 1 in good.

CONCLUSIONInternal fixation for the treatment of displaced clavicle fracture combined with coracoid process could restore physiological anatomical position of coracoid process, and benefit for recovery of limb function.

Objective To investigate the relationship of the changes of bone density and biochemical marker of bone turnover with osteoporosis in the elderly with type 2 diabetes mellitus(T2DM). Methods A total of 102 elderly patients with type 2 diabetes and 42 healthy subjects (normal controls) were included in this study.The bone mineral density (BMD) of lumbar vertebrae and femur were measured by dual-energy X-ray absorptiometry (DXA).The T2 DM subjects were divided into two groups:osteoporosis group (56 cases) and non-osteoporosis group (46 cases).The levels of total procollagen type Ⅰ amino-terminal propeptide (TP Ⅰ NP),β-isomerized carboxyterminal propeptide (β-CTx),parathyroid hormone (PTH),serum calcium (Ca2+),serum phosphorus (P),alkaline phosphatase (ALP),fasting blood glucose(FBG),glycosylated hemoglobin (HbAlc) and body mass index (BMI) were detected. The correlations between BMD of the osteoporosis group and other related factors were analyzed. Results The BMD values of lumbar vertebrae and femur neck,troch,ward's triangle in the osteoporosis group were decreased as compared with control(t=9.006,6.347,7.387,5.321,P＜ 0.01) and the serum TP Ⅰ NP,β-CTx,PTH,ALP,FBG,HbAlc,Creatinine and albumin/Cr in the osteoporosis group were significantly higher than controls(t=2.212,4.431,2.215,3.544,0.433,1.629,0.365,5.436,P＜0.01 or P＜0.05),the 25-(OH)VD3 in the osteoporosis group was lower than in controls(t=2.700,P＜0.01).Correlation analysis showed TP Ⅰ NP was negatively correlated with the BMD of femoral Troch and Ward's triangle (r=-0.413,-0.375,P＜0.01),and β CTx was negatively correlated with the BMD of femoral Troch (r=-0.301,P＜0.05).The TP Ⅰ NP,β-CTx in the overweight group and obesity group were higher than in normal group(F=50.59,51.28; F =96.20,95.71,all P＜0.01);the melbine group had higher TP Ⅰ NP,β-CTx than the thiazolidinedione and sulfonylurea group(F=32.33,33.35,F=31.07,39.18,P＜0.01);the TP Ⅰ NP,β-CTx in the better blood glucose control group were lower than in the bad control group(F=11.32,13.69,P＜0.01);the TP Ⅰ NP,β-CTx in the group with complication were increased as compared with no complication group(F=52.75,70.34,P＜0.01).Conclusions The spine BMD in elderly T2DM patients is decreased to some degree.The combined application of TP Ⅰ NP and β-CTx is helpful for the early diagnosis of osteoporosis in patients with type 2 diabetes.

Field avian infectious bronchitis virus (IBV) designated as JS/9 5/03, which was isolated from Jiangsu province of china, was cultivated in chicken emb ryo. It's single strain RNA was extracted from purified virus and worked as temp late of reverse transcription polymerase chain reaction (RT-PCR), a pair of pri mer designed according to megalign results of published IBV sequences in Genbank was used to amplify the neucleocapsid gene, the RT-PCR product was sequenced d irectly. Sequence analysis revealed that the sequence of JS/95/03 is most homolo gized with that of M41 strain.

Objective To study the relationship between the choice of operation and the efficacy on hepa- tolithiasis.Methods From Januray of 1995 to December of 2006,89 patients with hepatolithiasis underwent surgical treatment were retrospectively analyzed.Of them 33 cases underwent hepaticoplasty,hepatolobectomy in 7 cases, cholangiojejunostomy in 22 cases,choledocholithotomy with T-tube drainage in 27 cases.Results Out of the 89 cas- es,follow-up was completed in 81 cases for 6 months to 12 years.The postoperative stone residual rate of the group which underwent hepaticoplasty was 15.15 %(5/33)and cholannitis recurrence rate was 12.50 %(4/32),hepa- tolobecromy was 14.29%(1/7)and 16.67%(1/6),cholangiojejunostomy was 18.18%(4/22)and 30%(6/20), choledocholithotomy with T-tube drainage was 33.33 %(9/27)and 29.17 %(7/24).Conclusion Hepaticoplasty and hepatolobecromy were superior to cholangiojejunostomy and choledocholithotomy with T-tube drainage for treat- ment of hepatolithiasis.

Malignant tumors are major diseases that endanger human health. Due to their complex and variable microenvironment, most anti-tumor drugs cannot precisely reach the focal tissue and be released in a controlled manner. Intelligent responsive nano carriers have become a hot spot in the field of anti-tumor drug delivery systems. As an excellent nano material, mesoporous silica has the advantages of non-toxic, stable, adjustable pore volume and pore diameter, and easy functional modification on the surface. By virtue of its perceptive response to the tumor microenvironment or physiological changes, it can achieve the targeted drug release or controlled drug release of the drug delivery system in the tissue, making it an ideal carrier for intelligent response drug delivery system. In this paper, we review the design strategies and current research status of smart responsive anti-tumor drug delivery systems based on mesoporous silica, in order to provide a reference for the development of anti-tumor drug nanoformulations.
