The original purpose of establishing intellectual property law is to encourage the incentive to innovation. The anti-competitive exercise of intellectual property rights may adversely affect competition and innovation. The developed countries have tailored their competition laws by issuing guidelines and regulations to cover IP issues. The Chinese antimonopoly law 2008 only has Article 55 referring to the application of antimonopoly law to IP rights, it needs to be clarified. Appropriate competition law towards IP related area should be compatible with the socio-economic context of the country. The EU competition law model cannot be directly transplanted into China, due to its unique local context. This paper is to explore how to suggest appropriate ways to tailor Chinese antimonopoly law towards patent licensing related anti-competitive practices through the comparative study between China and EU.

Background: In physical activity or labor, the human body is in a state of high intensity stress, and allparts or physiological functions of the body respond positively to maintain or balance the need formovement. The human body has many physiological changes in the process of movement, and fatigue isthe external manifestation of various complex changes inside the human body. Fatigue is also a physiologicalmechanism of self-protection after the body reaches a certain level of activity, which can preventthe occurrence of life-threatening excessive functional failure. The generation of fatigue is a very complexprocess, and its mechanism has not been concluded yet. Therefore, it is an important work to search andscreen the effective components of natural plants that have anti-fatigue effect and to explore theirmechanism. Methods: This was a 8-week, randomized, double-blind, placebo-controlled clinical trial. A total of 110subjects who passed physical examination were included according to the scheme design, and randomlydivided into a test group which was given KRG and a placebo control group. The calculation is carried outaccording to the standard of sub-high-intensity exercise test. Results: There was no adverse effect on safety index of subjects after taking red ginseng capsule. AfterKRG treatment, subjective strength grade is significant lower than placebo treatment. Blood lactic acidcontent is significantly get lower after trial in KRG group, and significant lower than placebo group. Creatine phosphokinase(CK) content is significantly get lower after trial in KRG group, and significantlower than placebo group. Conclusion: According to the criterion in the test scheme, the result shows that KRG is helpful onrelieving physical fatigue.

Background/Aims: Real-world studies assessing the effectiveness and safety of sofosbuvir/velpatasvir (SOF/VEL) plus ribavirin (RBV) for Child-Pugh B/C hepatitis C virus (HCV)-related cirrhosis are limited. Methods: We included 107 patients with Child-Pugh B/C HCV-related cirrhosis receiving SOF/VEL plus RBV for 12 weeks in Taiwan. The sustained virologic response rates at off-treatment week 12 (SVR<sub>12</sub>) for the evaluable population (EP), modified EP, and per-protocol population (PP) were assessed. The safety profiles were reported. Results: The SVR<sub>12</sub> rates in the EP, modified EP and PP were 89.7% (95% confidence interval [CI], 82.5-94.2%), 94.1% (95% CI, 87.8-97.3%), and 100% (95% CI, 96.2-100%). Number of patients who failed to achieve SVR<sub>12</sub> were attributed to virologic failures. The SVR<sub>12</sub> rates were comparable regardless of patient characteristics. One patient discontinued treatment because of adverse events (AEs). Twenty-four patients had serious AEs and six died, but none were related to SOF/VEL or RBV. Among the 96 patients achieving SVR<sub>12</sub>, 84.4% and 64.6% had improved Child-Pugh and model for endstage liver disease (MELD) scores. Multivariate analysis revealed that a baseline MELD score ≥15 was associated with an improved MELD score of ≥3 (odds ratio, 4.13; 95% CI, 1.16-14.71; P=0.02). Patients with chronic kidney disease (CKD) stage 1 had more significant estimated glomerular filtration rate declines than patients with CKD stage 2 (-0.42 mL/min/1.73 ㎡/month; P=0.01) or stage 3 (-0.56 mL/min/1.73 ㎡/month; P<0.001). Conclusions: SOF/VEL plus RBV for 12 weeks is efficacious and well-tolerated for Child-Pugh B/C HCV-related cirrhosis. (Clin Mol Hepatol 2021;27:575-588)

In recent years, immunotherapy has emergedas a novel antitumor strategy in addition to traditional surgery,radiotherapy and chemotherapy. It uniquely focuses onimmune cells and immunomodulators in the tumor microenvironmentand helps eliminate tumors at the root by rebuildingthe immune system. Despite remarkable breakthroughs,cancer immunotherapy still faces many challenges: lack ofpredictable and prognostic biomarkers, adverse side eff ects,acquired treatment resistance, high costs, etc. Therefore,more effi cacious and effi cient, safer and cheaper antitumorimmunomodulatory drugs have become an urgent requirement. For decades, plant-derived natural products obtainedfrom land and sea have provided the most important sourcefor the development of antitumor drugs. Currently, moreattention is being paid to the discovery of potential cancerimmunotherapy modulators from plant-derived naturalproducts, such as polysaccharides, phenols, terpenoids, quinonesand alkaloids. Some of these agents have outstandingadvantages of multitargeting and low side eff ects and lowcost compared to conventional immunotherapeutic agents.

The objectives of this paper were to construct a full-length cDNA library and to isolate genes that confer salt tolerance from the leaves of salinity-tolerant wild eggplant variety, ‘Torvum Vigor’ (Solanum torvum Swartz). A full-length cDNA library from the leaves was successfully constructed by a switching mechanism at 5’-end of RNA transcript (SMART) approach and a long-distance PCR (LD-PCR) technique. The titer of the primary cDNA library was 3.6 ×106 cfu・mL-1 and that of the amplified library was 1.2 × 1010 cfu・mL-1. Gel electrophoresis results showed that most of the cDNA inserts ranged from 0.40 to 2.5 kb, with a recombination rate of 99%. A total of 427 randomly selected positive clones were sequenced. After removing the unsuccessful reads, 364 datasets were obtained and have been submitted to the NCBI Nucleotide Sequence Database under GenBank accession numbers JK265131-JK265494. Among the 364 submitted sequences, 74.45% of them contained full-length coding regions. BLASTX analysis revealed that 62.36% of the ‘Torvum Vigor’ expressed sequence tags (ESTs) possessed homology to known or putative proteins of other organisms. Seven genes that might be responsible for the encoding of known proteins in other organisms were identified to confer salt tolerance. This evidence demonstrated that the cDNA library constructed was a full-length library of high quality. It could be a useful resource for further research in the cloning of stress-related genes, which could be utilized in the genetic improvement of vegetable crops using transgenic technology.

Background: To explore the expression of DcR3 protein and its clinicopathological significance in bladder urothelial carcinomas (BUC). Materials and Methods: Immunohistochemistry was performed to detect the expression of DcR3, caspase-3, Bcl-2, VEGF, Ki-67, PCNA and P53 in 166 BUC and 56 normal bladder tissues. Western blotting was used to detect the expression of DcR3 in the supernatants of cultured BUC cells. Results: Overexpression of DcR3 was found in BUC tissues and cell lines, with significant elevation as compared to normal bladder tissues (p<0.0001). Higher DcR3 expression was related to the status of invasion, lymph node metastasis and recurrence. Furthermore, DcR3 expression was negatively correlated with caspase-3 and positively associated with Bcl-2, VEGF, Ki-67 labeling index (LI), PCNA LI and P53 (all p<0.0001), respectively. Conclusions: DcR3 may play a crucial role as an oncogene in tumorigenesis, deterioration and progress of BUC via influencing related pathways of apoptosis, proliferation and angiogenesis. The detection of DcR3 protein in the formalinfixed and paraffin-embedded samples could assist to predict in prognosis of BUC patients.
