ABSTRACT
Through the analysis of patent jurisprudence, it is proved that the Classical Prescription of Traditional Chinese Medicine (CPTCM) belongs to the scope of "existing technology" in the Law of Patent, and has lost the foundation of obtaining patent rights. Taking Japan's CPTCM as an example, based on the analysis of the administration of CPTCM and patent applications related to CPTCM in Japan, it is proved that CPTCM can not obtain patent authorization in Japan. Through the comparison of patent in China, the United States, Europe and worldwide region, it is proved that China is still the main source of patent applications for Traditional Chinese Medicine. At the end of the article, the author puts forward the suggestion of "active protection". It is believed that we should abandon the concept of patent-only protection and improve the influence of Traditional Chinese Medicine in worldwide from the aspects of industrial development, promotion ofits application, and intellectual property protection.

ABSTRACT
Objective To explore the risk factors for early rebleeding in patients with peptic ulcer bleeding (PUB) .Methods From June 2006 to May 2017 ,a total of 1210 hospitalized patients with PUB from The General Hospital of Ningxia Medical University were enrolled . Totally 1040 patients with bleeding stopped after the treatment were taken as the control group . And 170 patients with early rebleeding were as the rebleeding group .The clinical data of the patients in two groups were analyzed . Chi-square test ,t-test and multivariate factors analysis were performed for statistical analysis . Results Between control group and rebleeding group ,there were statistical significances in gender ,age ,place of residence , hematemesis , shock , volume of blood transfusion , anticoagulant use , combined diseases , hemoglobin level ,albumin level ,urea nitrogen ,neutrophil ratio ,platelet count ,ulcer location ,maximum ulcer diameter ,Forrest classification and endoscopic treatment (all P< 0 .05) .The rate of endoscopic hemostasis of rebleeding group (92 .56％ ,112/121) was lower than that of control group (98 .70％ ,228/231) , and the difference was statistically significant (χ2=13 .609 ,P=0 .001) .The result of multivariate logistic regression analysis showed that Forrest classification (odds ratio (OR)= 7 .735 , P< 0 .01) ,hemoglobin (OR=7 .332 ,P=0 .040) ,shock (OR=5 .245 , P<0 .01) and ulcer size (OR=2 .360 , P=0 .029) were independent risk factors for rebleeding in patients with PUB .The effect of Forrest classification better than hemoglobin ,hemoglobin better than shock and shock better than ulcer size in assessing the risk of rebleeding .Conclusions Forrest classification ,hemoglobin ,shock ,ulcer size are the risk factors for rebleeding in patients with PUB .Endoscopic hemostasis can reduce the risk of rebleeding .
ABSTRACT
Objective To analyze the risk factors of mortality in hospitalized patients with peptic ulcer bleeding (PUB).Methods From January 2003 to December 2012,1 210 patients with PUB were collected.Among them,1 170 patients were cured (cured group) and 40 patients died (dead group).The general information and clinical data of patients were collected,which included gender,age,smoking history,non-steroidal anti-inflammatory drugs intake,haematemesis,shock,blood infusion and rebleeding.The information of patients combined with other diseases was also collected.The lab findings and gastroendoscopy findings were also collected,including hemoglobin,platelets,serum albumin,blood urea nitrogen,serum creatinine levels,coagulation,location of ulcer and Forrest classification.Chi-square test was performed for comparison between groups of count data.The t-test was used for comparison between groups of measurement data and normally distributed,and Mann-Whitney rank sum test was used for non-normal distribution.The risk factors of mortality of patients with PUB were analyzed by univariate and multivariate Logistic regression analysis.Results The rates of age over 65,combined with other diseases,shock,rebleeding,abnormal coagulation,Forrest classification above Ⅱ b,medicine spraying to stop bleeding under gastroendoscope,gastroendoscopic hemostasis with titanium clip and operation of dead group (57.5％,23/40; 27.5％,11/40; 25.0％,10/40; 42.5％,17/40; 25.0％,10/40; 35.0％,14/40; 15.0％,6/40; 12.5％,5/40 and 17.5％,7/40) were all higher than those of cured group (25.0％,293/1 170; 7.4％,86/1 170; 12.5％,146/1 170; 13.1％,153/1 170; 5.1％,60/1 170; 20.9％,244/1 170; 4.8％,56/1 170; 4.1％,48/1 170 and 6.5％,76/1 170).The differences were statistically significant (x2 =21.117,18.651,5.400,27.728,9.203,4.613,6.332,4.661 and 5.710,all P＜0.05).The serum albumin level of dead group ((28.71±7.13) g/L) was lower than that of cured group ((32.82±7.55) g/L) and the difference was statistically significant (t=2.215,P＜0.05).Between the groups,there were no significant differences in gender distribution,rate of patients smoking,rate of patients taking non-steroidal anti-inflammatory drugs,rate of patients with haematemesis,volume of blood infusion,location of ulcer,dosage of proton pump inhibitor (PPI),average hemoglobin level,blood urea nitrogen level,serum creatinine and platelet count (all P＞0.01).Age over 65,combined with other diseases and rebleeding were the independent risk factors of mortality of patients with PUB during hospitalization (OR=4.821,12.959 and9.627,all P＜0.01).Conclusion Age over 65,combined with other diseases and rebleeding are the independent risk factors of mortality of patients with PUB during hospitalization.
