This study was aimed to analyze the similarities of characteristics between members of“metal family” in the five elements. Wittgenstein’s family resemblance theory was used in the analysis of members assigned to the category of“metal family”, which included metal, autumn, west, white, pungent and lung. The results showed that there was family resemblance between members of“metal family”. It was concluded that members were classified into the category of“metal family” through analogical reasoning of family resemblance. Any member to be classified as a member of“metal family” showed similarity with at least one of other family members. Certain member in the“metal family” had similarities in different aspects with multiple members in the family. Any two members of“metal family” may not always have any similarities. It can be deduced that certain physiological functions of lung were not owned by the lung itself, but by the characteristics of“metal family”. The range of“metal family” can be expanded and multiplied. The“metal family” can build new members in different areas.

In recent years,with the development of molecular biology,people gradually realize the tumor is composed of a series of development of the molecular mechanisms that trigger.The progress of targeted therapy for cancer patients brings new hope.Cetuximab through competitive combination with growth factor receptor blocking selective the growth of tumor cells,and achieved significant results.This is cetuximab in colo rectal cancer research progress of targeted therapy are reviewed in this paper.

This study was aimed to investigate renal protective effects and mechanism of Gui-Zhi(GZ) decoction in hyperuricemic mice.Potassium oxonate was used to induce hyperuricemia mouse model.Mice were randomly divided into 6 groups,which were the blank control group,model group,allopurinol group (5 mg·kg-1) and GZ decoction group (900,1 799 and 3 598 mg·kg-1).Hematoxylin eosin staining was used to observe the histopathological changes of renal tissues in mice.Commercial assay kits were used to measure levels of uric acid (UA),creatinine (Cr) and blood urea nitrogen (BUN) in serum and urine,as well as the xanthine oxidase (XOD) activity in liver.Renal protein levels of urate transporter 1 (URAT1),glucose transporter 9 (GLUT9),ATP-binding cassette G member 2 (ABCG2),organic cation transporter 1 (OCT1),OCT2,organic cation/carnitine transporter 1 (OCTN1) and OCTN2 were detected by western blot.The results showed that compared with the model group,GZ decoction can obviously decrease serum levels of UA,Cr and BUN,increase urine levels of UA and Cr,resulting in the elevation of fractional excretion of UA in hyperuricemic mice.Additionally,GZ decoction obviously inhibited hepatic XOD activity in hyperuricemic mice.Furthermore,GZ decoction downregulated renal URAT1 and GLUT9 protein levels,upregulated renal ABCG2,as well as OCT1,OCT2,OCTN1 and OCTN2 protein levels in hyperuricemic mice.It was concluded that GZ decoction had hypouricemic and renal protective effects in hyperuricemic mice,which might be associated with the reduction of UA production via inhibiting hepatic XOD activity,promoting UA and other organic ion excretion via regulating renal organic ion transporter protein levels.

Objective To summarize and analyze the effect of hand hygiene(HH)cost on the incidence of health-care-associated infection (HAI),evaluate continuous improvement method,and provide data for hospital manage-ment.Methods The cost of HH project and incidence of HAI in a hospital from January 2013 to June 2014,as well as HH compliance in the first half year of 2014 were investigated.Results Semiannual statistics were performed, the cost of HH project in the first half of 2013,second half of 2013,and first half of 2014 were 283 490,414 232, and 522 345 yuan respectively,compared with the first half of 2013,the cost of HH in the first half of 2014 in-creased by 84.26%;incidence of HAI were 3.13%,3.33%,and 3.03% respectively,difference was significant(χ2=10.37,P <0.001).In the first half of 2014,HH compliance rate increased from 35.00% in January to 59.49% in June.The top three factors that affecting the implementation of HH were busy work,had no time for handwashing;inadequate HH facilities or supplies;inadequate knowledge about HH.Conclusion Increasing the investment of HH products can improve HH compliance and reduce the incidence of HAI.

ObjectiveTheaimofthisstudywastoprovideabetterpositivecontrolforallergictestbycomparing the allergic effect of two kinds of positive materials , human albumin and ovalbumin , on active systemic anaphylaxis in guinea pig.Methods Guinea pigs were randomly divided into 14 groups, and were given human albumin , ovalbumin (2, 10, 100 mg/animal), or 0.9%sodium chloride injection as test substances , to assess the symptoms and incidence of systemic allergic responses induced by different sensitizing substances in different challenge doses and different challenge intervals.Results In the range of 2 to 100 mg/animal, the guinea pigs showed a 100%incidence rate of positive allergic reaction to human albumin and ovalbumin , the severity of anaphylactic symptoms was increasing along with the increase of sensitizing doses and challenge doses , and the allergic reaction was more strong induced by the same dose of ovalbumin than human albumin .Conclusions Our findings indicate that in the active systemic anaphylaxis test in guinea pigs , we recommend ovalbumin as the positive control in a dose of 2 mg/animal.

Objective To evaluate the treatment of interapleural talc on the patients with malignant pleural effusion.Method There were 44 patients with malignant pleural effusion in the study.Every cases was inserted a chest drain to release the effusion with the rate of 200 ml per 2 hours.When there was no evidence of fluid in the pleural space as assessed by plain chest roentgenography,the talc slurry containing 4 g talc、40 ml of saline solution (0.9%) and 5 ml of 2% lidocaine was injected via the intercostal drain into the pleural space.An additional 20 ml of saline solution was used to flush the drain.Then,the drain was clamped,and the patient was asked to change position to allow adequate distribution of talc.After 2 hours,the drain was opened again.When the drainage decreased to less than 150 ml per 24 hours,the chest drain was removed.Result complete success was observed in 36 cases (81.8%),partial success in 6 cases (13.7%),and ineffective success in 2 cases (4.5%).There were 21 (47.7%) and 24 (54.4%) cases experienced pleuritic pain and fever after talc pleurodesis respectively,1 cases suffered from respiratory insufficiency which controled by using glucocorticoid later.Conclusion The talc pleurodesis is an effective treatment for the patients with malignant pleural effusion.It is safe and easily performed,and should be used extensively in clinic.

Objective To evaluate the clinical effect of splenic internal jugular shunt for Budd Chiari Syndrome (BCS). Methods A retrospective analysis was made on the clinical data of 21 patients of BCS who underwent this operation. Results There was no death in 21 patients receiving this operation, The average post operative reduction of FPP was 0.97Kpa.2 suffered postoperative lung infection . Abdominal incision infection occurred in one patient. Tweenty cases were followed up for one month to forty five months. Lower extremity varicose veins and abdomen wall varicose veins basically disappeared a month postoperatively; ascites vanished completely 3 months postoperatively,and lower limb ulcer healed 6 months postoperatively. Seventeen patients followed by CDFI showed that no thrombus was found in their artificial vessel. Barium meal studies in 12 cases displayed that oesophageal varicose veins had basically disappeared during the follow up period. Conclusions Splenic jugular shunt bridged by artifical vessel is safe,effective and less traumatic for patients with type III and some patients with type II Budd Chiari syndrome. It is currently the best choice for treatment of BCS.
