To prepare bio-degradable albumin microspheres containing carboplatin. METHODS: Bovin serum albumin microspheres containing carboplatin were prepared by using emulsion-direct heat cross linking techniques. RESULTS: The microsphere was yellow, powdery, with a mean diameter of 58.2 μm. The microphere loaded (11.26±0.48)% carboplatin. The trapping efficiency was (84.5±3.6)%. The pattern of drug releasing from the microspheres in vitro fitted to zero order release plot, with an initial burst in the first 2 hours. The releasing rate can be expressed by the follow equation: Q=21.90+8.50 t (d), r=0.995 8. t50=3 d. Stored at 4 ℃ and 37 ℃ respectively for 3 months, the microspheres did not alter much in shape, size and drug content. CONCLUSIONS: This method is simple, reproducible, having high drug trapping efficiency. The microsphere obtained is stable and release drug at a consistant rate in vitro, leading to a prosperity in clinical use.

Objective:To study the protective effect of electroacupuncture on stem cell proliferation and differentiation in dentate gyrus (DG) in aged rats with focal cerebral ischemia reperfusion injury. Methods:We duplicated focal cerebral ischemia model with MCAO,with ischemia 3h,I/R1,3,7,14,21d points. The effect of electroacupuncture on the nervous dysfunction score,the water content of cerebral constitution and the stem cell proliferation and differentiation in dentate gyrus were observed,and the non-acupoint group was as control. Results:The nervous dysfunction score (all the time points),the water content of cerebral tissue (I/R1,3,7d),BrdU positive cells (all the time points),BrdU/NeuN positive cells (all the time points),BrdU/GFAP positive cells (I/R7,14,21d),in model group were higher than those of the sham-operated group (P

This study is to investigate the effect of FK506 on expression of hepatocyte growth factor (HGF) in rats' spinal cord following peripheral nerve injury and to elucidate the mechanisms for neuroprotective property of FK506. Fifty male rats were randomly divided into normal group, injury group and treatment group. Models of peripheral nerve injury were established by bilateral transection of sciatic nerve 0.5 cm distal to piriform muscle. Then the treatment group received subcutaneous injection of FK506 (1 mg/kg) at the back of neck, while the injury group was given 0.9% saline. The L(4-6) spinal cords were harvested at various time points after the surgery. Western blotting and immunofluorescent staining were used to detect the level and position of HGF in spinal cord. Immunofluorescent staining showed that HGF-positive neurons were located in anterior horn, intermediate zone and posterior horn of gray matter in normal spinal cord. Western blotting revealed that there was no significant difference in the expressions of HGF between the injury group and the normal group, while the expression of HGF was significantly higher in the treatment group than in the injury group 7 and 14 days after surgery. It is suggested that peripheral nerve injury does not result in up-regulation of the expression of HGF in spinal cord, while FK506 may induce high expression of endogenous HGF after injury thereby protecting neurons and promoting axonal outgrowth.

Objective To systematically evaluate the risk factors for upper extremity lymphedema after breast cancer treatment and the strength of their associations.Methods PubMed,Ovid,EMbase,and the Cochrane Library were searched to identify clinical trials published up to December 2012.The quality of included studies was assessed by the Newcastle-Ottawa Scale;data analysis was performed by Stata 10.0 and RevMan 5.2;the strength of associations between risk factors and breast cancer-related upper extremity lymphedema was described as odds ratio (OR) and 95％ confidence intervals (CI).Results Twenty-two studies involving 10106 patients were included in the meta-analysis.The risk factors for upper extremity lymphedema after breast cancer treatment mainly included axillary lymph node dissection (OR =2.72,95％ CI=1.06-6.99,P=0.038),hypertension (OR=1.84,95％ CI=1.38-2.44,P=0.000),body mass index (OR =1.68,95％ CI=1.22-2.32,P =0.001),and radiotherapy (OR =1.65,95％ CI =1.20-2.25,P =0.002),while no significant associations were found for such factors as chemotherapy,age,number of positive lymph nodes,and number of dissected lymph nodes.Conclusions The incidence of upper extremity lymphedema is high among patients with breast cancer after treatment,and axillary lymph node dissection,hypertension,body mass index,and radiotherapy are the main risk factors for lymphedema after breast cancer treatment.

Purpose:The value of color doppler ultrasonography( CDUS) in monitoring hemodynamic changes was investigated in patients with hyperdynamic circulatory state before and during 730 days after orthotopic liver transplantation.Materials and Methods:83 cases of orthotopic liver transplantation (OLT) were examined by CDUS to assess the hemodynamic changes of portal vein,hepatic artery,splenic artery and longitudinal diameter of the spleen ( LDS).Results:(1) Portal flow velocity ( PFV) was significantly lower in pre-OLT but higher than controls (P < 0.05 ) during 730 days after OLT.Resistance index of the hepatic artery ( HARI) in pre-OLT and within 7 days- after OLT was significantly higher (P<0.05).(2) Resistance index of splenic artery ( SARI) was also significantly higher in pre-OLT (P < 0.05 ).LDS was significantly higher after OLT than in both pre-OLT phase and controls(P<0.05).Conclusions: In early stage after OLT,HARI changed from high to low value and so did PFV,which kept the stability of hepatic blood flow.In late stage,high PFV and large spleen improved,but could not back to normal.

Objective To investigate the intervention of Chinese herb Shengjiang San(SJS)for the imbal-ances of serum Th1/Th2 cells and related regulatory factors in sepsis patients. Methods Fifty-five sepsis patients were randomly divided into two groups:conventional treatment group of 27 cases and SJS group of 28 cases. Nine cases of healthy volunteers were enrolled as control group in the study. Cases of conventional group were treated with western medicine only and cases of SJS group were treated with both western medicine and Chinese herb SJS (100 mL twice one day). The therapy course of both groups was 3 days. Score of Chinese medical syndromes ,se-rum level of leukocyte count,C reactive protein(CRP)and procalcitonin(PCT),serum T-bet,GATA-3,Th1&Th2 cells in the proportion of whole CD4+Th cells and Th1/Th2 ratio were compared respectively in each group be-fore and after treatment. Results There were significant differences between SJS group and conventional group in score of Chinese medical syndromes,serum level of leukocyte count,T-bet,GATA-3,Th1&Th2 cells in the pro-portion of whole CD4+Th cells and Th1/Th2 ratio(P<0.05 or P<0.01). There were no significant differences be-tween the two groups in serum level of CRP,PCT and GATA3. Compared with control group,there were signifi-cant differences in all indicators except GATA3 of the two groups(P<0.01). Conclusion Chinese herb Shengji-ang San has an effective benefits to Chinese medical syndromes,inflammatory reaction,the imbalance of serum Th1/T2 and related regulatory factors(T-bet&GATA-3)in sepsis patients.
