Objective BALB/C mice were inoculated subcutaneously with hepatoma 22 (H22) cells, and the treatment effect of thalidomide and intratumor injection of ethanol extract of Scutellaria Barbata (SB) on tumor growth were evaluated. Methods In vitro, mouse H22 liver cells were cultivated, and H22 cells in the logarithmic growth phase were tested. SB was extracted in the ethanol recirculation. A total of 28 BALB/C male mice inoculated subcutaneously with H22 cells were randomly divided into 4 groups, 7 mice per group. Group A:intragastric administration with thalidomide. Group B:SB intratumor injection. Group C:combination of thalidomide and SB with the same administration as Group A and Group B. Group D (control group):1% Ethanol 0.2~0.5 mL intratumor injection. Tumor volumes of four groups were observed and the tumors were weighed. The microvessel densities (MVD) of all transplantation tumors were measured by immunohistochemical staining with anti-CD31 monoclonal antibody. Results There were statistically significant differences between Group C and Group A (P 0.05). The studies showed statistically differences between Group C and Group A (P

Construction of artificial cell factory to produce specific compounds of interest needs wild strain to be genetically engineered. In recent years, with the reconstruction of many genome-scale metabolic networks, a number of methods have been proposed based on metabolic network analysis for predicting genetic modification targets that lead to overproduction of compounds of interest. These approaches use constraints of stoichiometry and reaction reversibility in genome-scale models of metabolism and adopt different mathematical algorithms to predict modification targets, and thus can discover new targets that are difficult to find through traditional intuitive methods. In this review, we introduce the principle, merit, demerit and application of various strain optimization methods in detail. The main problems in existing methods and perspectives on this emerging research field are also discussed, aiming to provide guidance to choose the appropriate methods according to different types of products and the reliability of the predicted results.

ObjectiveTo discuss the clinical efficacy of hyperextension reduction with percutaneous kyphoplasty in treatment for osteoporotic vertebral compression fracture.MethodsTwenty-three patients with 23 vertebral compression fractures underwent hyperextension reduction with percutaneous kyphoplasty from September 2010 to October 2011.The vasual analogue scale(VAS) score and complications were recorded during followed up.Results All cases were successfully experienced the procedure using unilateral or bilateral percutaneous pedicle underwent hyperextension reduction.The operation time was (75 ± 45) minutes,the mean volume of cement injected into each vertebral body was(4.9 ± 1.9) ml.All patients had successful intervention without spinal cord injury,pulmonary embolism.Followed up(7.5 ± 6.5 ) months,the symptoms of the patients were improved,preoperative VAS score was (7.5 ± 0.7 ) scores,reduced to (3.4 ±0.4) scores at day 1 postoperatively,(2.7 ±0.5) scores at day 7 postoperatively and (2.3 ±0.5) scores at month 1 postoperatively,there was significant difference between preoperative and postoperative (P< 0.05).ConclusionsApplication of hyperextension reduction with percutaneous kyphoplasty can relieve pain and restore the vertebral body height,it may be an effective treatment method for patients with osteoporotic vertebral compression fracture.

HPLC was conducted to determine the content of carbinoxamine maleate,release degree of original preparations and self-made suspensions was compared,drug-loading capacity was calculated. RESULTS:The drug amount in preparing drug-loaded resin was 2%,reaction temperature was 25 ℃,and reaction time was 4 h;the drug-loading capacity in surface coating was 35%,amount of coating material was 10%,and reaction temperature was 40 ℃. The drug-loading capacities of sustained particles before and after coating were 35.23%,32.72%,respectively;the yield was 96.82%. The carbinoxamine ma-leate in prepared sustained-release suspension accounted for 98.76% of the labeled amount;release degree in 10 h reached about 80%,f2 was 65.73. CONCLUSIONS:Carbinoxamine maleate sustained-release suspension is prepared successfully,and its release is similar to the original preparation.
