Abstract
Objective: To evaluate the hemostatic efficacy, safety and immunogenicity of recombinant human thrombin in the treatment of liver wounds that still ooze after conventional surgical hemostasis. Methods: A multicenter, stratified randomized, double-blind, placebo-controlled phase Ⅲ trial with a planned enrollment of 510 subjects at 33 centers, with a 2∶1 randomization to the thrombin group versus the placebo group. An interim analysis will be conducted after approximately 70% of the subjects have completed the observation period. The primary efficacy endpoint was the rate of hemostasis within 6 minutes at the point of bleeding that could be evaluated. Safety analysis was performed one month after surgery, and the positive rates of anti-drug antibody (ADA) and neutralizing antibody were evaluated. Results: At the interim analysis, a total of 348 subjects had been randomized and received the study drug (215 were male and 133 were female). They were aged 19-69 (52.9±10.9)years. Among them, 232 were in the thrombin group and 116 were in the placebo group, with balanced and comparable demographics and baseline characteristics between the two groups. The hemostasis rate at 6 minutes was 71.6% (95%CI:65.75%-77.36%) in the thrombin group and 44.0% (95%CI: 34.93%-53.00%) in the placebo group, respectively (P<0.001). No grade≥3 drug-related adverse events and no drug-related deaths were reported from the study.No recombinant human thrombin-induced immunologically-enhanced ADA or immunologically-induced ADA was detected after topical use in subjects. Conclusion: Recombinant human thrombin has shown significant hemostatic efficacy and good safety in controlling bleeding during liver resection surgery, while also demonstrating low immunogenicity characteristics.

Abstract
As a gene therapy strategy, RNA interference (RNAi) offers tremendous tumor therapy potential. However, its therapeutic efficacy is restricted by its inferior ability for targeted delivery and cellular uptake of small interfering RNA (siRNA). This study sought to develop a dual-ligand nanoparticle (NP) system loaded with siRNA to promote targeted delivery and therapeutic efficacy. We synthesized a dual receptor-targeted chitosan nanosystem (GCGA), whose target function was controlled by the ligands of galactose of lactobionic acid (LA) and glycyrrhetinic acid (GA). By loading siPAK1, an siRNA targeting P21-activated kinase 1 (PAK1), a molecular-targeted therapeutic dual-ligand NP (GCGA-siPAK1) was established. We investigated the synergistic effect of these two targeting units in hepatocellular carcinoma (HCC). In particular, GCGA-siPAK1 enhanced the NP targeting ability and promoted siPAK1 cell uptake. Subsequently, dramatic decreases in cell proliferation, invasion, and migration, with an apparent increase in cell apoptosis, were observed in treated cells. Furthermore, this dual-ligand NP gene delivery system demonstrated significant anti-tumor effects in tumor-bearing mice. Finally, we illuminated the molecular mechanism, whereby GCGA-siPAK1 promotes endogenous cell apoptosis through the PAK1/MEK/ERK pathway. Thus, the dual-target property effectively promotes the HCC therapeutic effect and provides a promising gene therapy strategy for clinical applications.

Abstract
Photodynamic therapy (PDT) is an effective oncotherapy and has been approved for clinical application. Unfortunately, its therapeutic efficacy is usually overshadowed by tumor angiogenesis. Thus, a detailed understanding of the tumor angiogenesis upon PDT is imperative. This study aimed to investigate the potential contribution and mechanism of P-21-activated kinase 1 (PAK1) in PDT-induced tumor angiogenesis. Firstly, we found that PAK1 was upregulated upon PDT and associated with tumor angiogenesis. Then, we elucidated the underlying molecular mechanism. Activation of PAK1 prevents hypoxia-inducible factor 1 alpha (HIF-1α) protein from ubiquitin-mediated degradation. Thereafter, HIF-1α accumulation results in the upregulation of vascular endothelial growth factor (VEGF), thus promoting tumor angiogenesis. More importantly, we determined that PAK1 knockdown effectually repressed tumor angiogenesis, which contributes to enhance the therapeutic effect of PDT. Together, PAK1 is a potential novel pharmaceutical target for inhibiting PDT-induced tumor angiogenesis, and PAK1 suppression in combination with PDT may be a potentially effective strategy for anti-tumor therapy.

Abstract
Photosensitizer (PS) serves as the central element of photodynamic therapy (PDT). The use of common nanoparticles (NPs) for PDT has typically been rendered less effective by the undesirable aggregation-caused quenching (ACQ) effect, resulting in quenched fluorescence and reduced reactive oxygen species (ROS) generation that diminish the imaging quality and PDT efficacy. To overcome the ACQ effect and to enhance the overall efficacy of PDT, herein, integrin ανβ3-targeted organic nanodots for image-guided PDT were designed and synthesized based on a red emissive aggregation-induced emission (AIE) PS. Methods: The TPETS nanodots were prepared by nano-precipitation method and further conjugated with thiolated cRGD (cRGD-SH) through a click reaction to yield the targeted TPETS nanodots (T-TPETS nanodots). Nanodots were characterized for encapsulation efficiency, conjugation rate, particle size, absorption and emission spectra and ROS production. The targeted fluorescence imaging and antitumor efficacy of T-TPETS nanodot were evaluated both in vitro and in vivo. The mechanism of cell apoptosis induced by T-TPETS nanodot mediated-PDT was explored. The biocompatibility and toxicity of the nanodots was examined using cytotoxicity test, hemolysis assay, blood biochemistry test and histological staining. Results: The obtained nanodots show bright red fluorescence and highly effective 1O2 generation in aggregate state. Both in vitro and in vivo experiments demonstrate that the nanodots exhibit excellent tumor-targeted imaging performance, which facilitates image-guided PDT for tumor ablation in a hepatocellular carcinoma model. Detailed analysis reveals that the nanodot-mediated PDT is able to induce time- and concentration-dependent cell death. The use of PDT at a high PDT intensity leads to direct cell necrosis, while cell apoptosis via the mitochondria-mediated pathway is achieved under low PDT intensity. Conclusion: Our results suggest that well-designed AIE nanodots are promising for image-guided PDT applications.

Abstract
Photodynamic therapy (PDT) is a palliative technique that can improve median survival with minimal invasion for cholangiocarcinoma (CC) patients. An ideal photosensitizer (PS) is critical to guarantee the efficacy of PDT. However, conventional PSs have some obvious drawbacks, such as lack of specificity and easy aggregation in aqueous media that limit their further application in the clinic. We herein fully take advantage of a red emissive aggregation-induced emission (AIE) PS to fabricate integrin ανβ3 targeted organic AIE dots for image-guided PDT via a simple and straightforward one-step strategy. The obtained AIE dots exhibit high specificity to CC as well as excellent antitumor effect both in vitro and in vivo. Different from conventional PSs and previously reported PS-loaded nanostructures, the AIE dots do not suffer from aggregation-caused fluorescence quenching and reduction in reactive oxygen species production when the AIE PS molecules are in an aggregated state. The significant antitumor effect, as well as good biocompatibility and negligible toxicity, makes the AIE dots promising for future translational research in CC diagnosis and therapy.

Abstract
Hepatocellular carcinoma (HCC) is the most common primary liver cancer with high morbidity and mortality worldwide. Chemotherapy is recommended to patients with intermediate or advanced stage cancer. However, the conventional chemotherapy yields low desired response rates due to multidrug resistance, fast clearance rate, nonspecific delivery, severe side effects, low drug concentration in cancer cells, and so on. Nanoparticle-mediated targeted drug delivery system can surmount the aforementioned obstacles through enhanced permeability and retention effect and active targeting as a novel approach of therapeutics for HCC in recent years. The active targeting is triggered by ligands on the delivery system, which recognize with and internalize into hepatoma cells with high specificity and efficiency. This review focuses on the latest targeted delivery systems for HCC and summarizes the ligands that can enhance the capacity of active targeting, to provide some insight into future research in nanomedicine for HCC.

Abstract
Toll-like receptor (TLR) signaling has been implicated in inflammatory-related cancers. The upregulation of TLR signaling in hepatocellular carcinoma (HCC) suggests that it may play an essential role in the prognosis of chronic and inflammatory diseases that ultimately culminate in HCC. Here, we provide evidence about the involvement of the TLR pathway in the initiation, progression, and metastasis of HCC. The differential expression of TLR in epithelial cells has also been discussed. In particular, we emphasize the physiological role of TLR4 in the development and pathogenesis of HCC and propose novel and promising approaches for HCC therapeutics with the aid of TLR ligands.

Abstract
In order to improve the embryogenic callus induction rate and the regeneration rate of JiaHe-ZaoZhan rice, the influence of different factors were investigated, media with different hormones were used. Induction medium was supplemented with 1.5 mg/L 2,4-D + 3 mg/L NAA + 0.1 mg/L KT + 1 mg/L phytic acid + 20 mg/L PAA. Embryogenic call were treated under the condition of 25 degrees C before transferring to regeneration medium, the regeneration medium contained 0.5 mg/L 6-BA + 3 mg/L NAA + 0.5 mg/L KT + 1 mg/L phytic acid. The experiment results indicated that the hormone treatments had certain effects on the callus induction. Under the optimal medium, culture condition and the hormone treatments, the embryogenic callus induction could reach over 95%, and dry treatment of embryogenic callus had been found to increase the frequency of plant regeneration, significantly the plant regeneration rate could reach over 80%. Transplanted into pots, the young plants grew well. Then a experimental system with stability and high regenerating efficiency has been established for the mature seeds of rice (JiaHe-ZaoZhan).

Abstract
In this study 12 Japanese long ear rabbits were used as models of acute cholangitis of severe type (ACST), and also an increasing pressure apparatus of self-made caecus to form high pressure of the biliary tract. The animals were observed for changes in blood dynamics in an attempt to explore the effect and relation of high pressure of biliary tract and infective element in pathogenesis of ACST. It was found that when the biliary pressure was increased within 120 min in the 20 kPa group, the blood endotoxin level showed no obvious increment (P > 0.05), but the decreased range of average MAP (mean artery pressure) was over 4 kPa, and the cardiac output also decreased evidently (P < 0.05), and that when the biliary pressure was decreased, MAP and cardiac output were restored to normal gradually. Of these animals 3 didn't restore their normal condition when the blood pressure decreased to zero and died finally. Meanwhile the electric discharge frequency of the right greater splanchnic nerves increased (P < 0.05), but when pressure was reduced, the frequency slowed down. From the above findings, the authors came to the conclusion that the rapid increase of the biliary tract pressure is the important factor leading to a decrease in blood pressure of ACST, and even bringing about irreversible shock, which is involved in the activity of splanchnic nerves.

Abstract
In order to study the mechanism of decreased blood pressure caused by an acute increase in biliary tract pressure, we observed house rabbit model of self-made caecus for changes in cardiovascular function when biliary tract pressure was increased. It was found that both the blood pressure and cardiac output evidently decreased (P < 0.05) parallelly, and the systolic pressure decreased more markedly than diastolic pressure. At the same time there was fluctuation in heart rate and in central venous pressure; but there was no significant difference between them (P > 0.05), suggesting that in the absence of infective agents, the increased biliary tract pressure can bring about a decrease in cardiac output, which is an important factor contributing to an early blood pressure decrease in acute cholangitis of severe type (ACST).
