Esophageal carcinoma represents high incidence and mortality rate in China.Irinotecan (CPT-11) has shown promising activity in a number of gastrointestinal cancers,including esophageal cancer.This article reviews recent clinical trials of irinotecan-based chemotherapy and radiochemotherapy in esophageal carcinoma.

[Objective]To explore improved operation treatment of fractures of olecranon and internal or external malleolus by fixing them internally with needle wire amend tension band.[Method]A total of 89 cases of olecranon fracture and 63 cases of internal and external malleolus fracture were treated by the amended traditional tension belt using needle wire nails.[Result]Sixty-eight and 55 of these cases(80.9%) had been followed-up respectively for 2.5 years in average,the longest follow-up period was 5 years and the shortest was 6 months.It shows through evaluation with Wolfgang post curative standard that 65 and 53 cases were excellent in curative effect(95.9%),3 and 2 cases had moderate result(4.1%),and there was no worse case.The average fracture cure time was 1.5 months.[Conclusion]The improvement of traditional tension belt in olecranon and internal or external malleolus fracture operation by using needle wire nails has the following advantages:(1)Simplifying operation procedures;(2)Reducing number of steel nails;(3)Keeping the biomechanical principle of the tension band and internal AO fixing advantage;(4)Reducing the phenomena of "tension loss" caused by expanded steel wire holes as a result of osteonecrosis,and avoiding internal loose complication.The disadvantage of this method is that the fixation has to be taken out through operation.

The quality management of drug research,development,registration,production and marketing strengthened by good practice for pharmaceuticals ensure the drag safety,effectiveness and quality control.Teaching of new drug research and evaluation in compliance with good practice for pharmaceuticals will be of value in making teaching content close to actual work,extending the students'knowledge and training student's good habits in scientific study.

Objective To elucidate the effect of multi-kinase inhibitor sorafenib on anaplastic thyroid carcinoma cells in the presence or absence of metformin.Methods SW1736 and C643 cells were treated with sorafenib in the presence or absence of metformin for various periods of time.Cell viability was detected by MTT.Cell cycle and cell apoptosis were measured by flow cytometry.Caspase-3 activity was detected by colorimetric kit.Western blot was used to analyze pERK phosphorylation and cyclinD1 expression.Results Sorafenib inhibited the growth of anaplastic thyroid carcinoma cells and induced cell cycle arrest and cell apoptosis.The EC50 of sorafenib in SW1736 and C643 was 3.68 μmol/L and 4.87 μmol/L respectively.After sorafenib ± metformin treatment,the caspase3 activity was 131.5 ％ and 278.0％ (P＜0.01) in SW1736 cells,127.2％ and 196.6％ (P＜0.01) in C643 cells.On the molecular level,sorafenib inhibited the phosphorylation of ERK and decreased the expression of cyclinD1.Metformin amplified the growth inhibitory effect of sorafenib on anaplastic thyroid carcinoma cells.The cell viability was 0.76 ± 0.17 and 0.30 ± 0.04 (P＜0.01) in SW1736 cells,0.72 ± 0.09 and 0.34 ± 0.10 (P＜0.001) in C643 cells after 2.5 μmol/L sorafenib without or with 5 mmol/L metformin treatment.Conclusions The combination of sorafenib and metformin may be a potent strategy for the treatment of anaplastic thyroid carcinoma and other advanced cancers.

The standard research platform construction is one of the business construction tasks in the national Chinese medicine clinical research base. The base of HuBei province focused on tasks of base construction, clinical scientific research of key disease study to present the idea and method of standard research platform construction in order to complete the construction task .

Objective To investigate the effect of elispheric motion on balance and walking ability of hemiplegic patients after stroke. Methods From September to December, 2016, 40 hemiplegic patients after stroke were randomly divided into control group (n=20) and ob-servation group (n=20). Both groups received conventional rehabilitation, additionally, the control group received juggling ball training, and the observation group received elispheric motion combined with juggling ball training, 20 minutes a day, six days a week for six weeks. They were assessed with the Fugl-Meyer Assessment-Sensory (FMA-S), Fugl-Meyer Assessment-Lower Extremity (FMA-LE), Berg Bal-ance Scale (BBS) and TimedUp and GoTest (TUGT) before and six weeks after training. Results After training, the scores of FMA-S, FMA-LE, BBS significantly increased (t>10.012, P<0.05) in both groups, and were higher in the observation group than in the control group (t>2.129, P<0.05);the time of TUGT significantly shortened (t>10.001, P<0.001) in both groups, and were shorter in the observation group than in the control group (t>4.669, P<0.05). Conclusion Elispheric motion can facilitate to improve the balance and walking ability of hemi-plegic patients after stroke.

OBJECTIVE To determine pathogens and drug resistance of lower respiratory tract infection in patients receiving mechanical ventilation in ICU and to provide the reference for clinical prevention and treatment.(METHODS) The ages,underlying diseases,pathogens distribution and resistance rate of Gram-negative bacteria of 110 cases patients receiving mechanical ventilation and being complicated lower respiratory tract infection in ICU were investigated.RESULTS Totally 110 strains of pathogens were isolated by bacterial culturing.The ratio of the Gram-negative bacteria to total bacteria isolated was 72.7%(80 strains) and of the Gram-positive bacteria was(18.2%)(19 strains),of the fungi was 10%(11 strains),among them the Pseudomonas aeruginosa contributed the majority,and ESBLs accounted for 38.8%,MRSA contributed 31.6% in Staphylococcus.Multidrug-(resistance) of Gram-negative bacteria to antimicrobial agents was serious.CONCLUSIONS Gram-negative bacteria are the majority of the pathogens,isolated from patients with lower respiratory tract infection in ICU receiving mechanical ventilation.It is suggested that there be urgent need for surveillance of bacterial resistance and rational use of antimicrobial(agents) during clinical therapy.

Objective:To observe the applications of damage control surgery(DCS) theory in selective abdominal operations.Methods:Two patients suffered from abdominal huge tumour were included in this clinical observation.DCS method was used in the first case when uncontrollable haemorrhage happened in the operation.In the second case,the DCS method was planed before operation.Results:Both the two patients were healed.The second one had no dangerous states after operation.Conclusion:In selective abdominal operation,perioperative DCS method should be considered if some life-threatening risks may happen in the operative procedure.
