Abstract:
Ribosomal proteins (RP) are important components of ribosomes and play key roles in ribosome biogenesis and protein translation. In addition, ribosomal proteins also possess many extra-ribosomal functions, such as regulation of gene expression, cell proliferation, differentiation, apoptosis, DNA repair, and many other cellular processes. The dysfunction of RP is closely related to the occurrence and development of various diseases including blood, metabolism, cardiovascular diseases and tumors, and RP might become potential therapeutic targets for a variety of diseases. The research progress on RP, including the basic functions of RP, extra-ribosomal properties, and the connections with human diseases were reviewed and their potential as biomarkers and therapeutic targets in diseases were discussed in this paper.

Abstract:
Solenopsis invicta is a kind of invasive pest that causes serious damage to local agriculture, environment, and human health. They attack mainly with venom within stingers. Those who are allergic to the venom would suffer a systemic anaphylaxis, even fatal shock, after being stinged by these ants. Many studies reveal that their venom is mainly composed by water, insoluble alkaloids and trace proteins, within which alkaloids are the main cause of burning sensation and blisters, while allergic reactions are caused by proteins or peptides. The research progress of toxic substances in the venom of Solenopsis invicta as well as the roles and functions of each component were reviewed in this paper.

Abstract:
Objective To provide theoretical reference and practical basis for accurately choosing the suitable packaging forms for different Injections. Methods Based on the raw materials in the common packaging forms of injections, the research and application progress on different packaging forms for injections were reviewed by analyzing the characteristics and technical requirements of different packaging forms, and the current registration information of pharmaceutical packaging materials in the Center for Drug Evaluation, NMPA were introduced. Results For preparations with small single-dose and low-cost, the ampoules or injection vials could be chosen. Powder injections are usually packaged in injection vials. For rescue medicines and valuable medicines, the pre-filled syringes could be chosen. For chronic disease treatment drugs (such as insulin) that require long-term injection, or some injections for emergency use, a pen-type syringe package that patients can inject themselves could be used. Neutral glass packaging or plastic packaging should be used for some acidic or alkaline. Conclusion The drug manufacturers should comprehensively consider the physicochemical properties of drugs, the performance of packaging raw materials, compatibility test results, price-cost, and convenience in carrying and use when choosing the appropriate packaging form to ensure the quality, safety, and effectivity of drugs.

Abstract:
Linear ubiquitination is an important post-translational modification that has been discovered in recent years. The linear ubiquitin chain is formed by the linkage of glycine residue of one ubiquitin protein to the methionine residue of another ubiquitin. This process is regulated by the linear ubiquitin chain assembly complex (LUBAC) and the OTU deubiquitinase with linear linkage specificity (OTULIN). Linear ubiquitination is involved in various biological processes, including immune response, inflammation, and cell apoptosis. Recent studies have shown that linear ubiquitination is closely related to the occurrence, development, and drug resistance of tumors by affecting signaling pathways such as NF-κB and Wnt/β-catenin. The research progress on the function of LUBAC and OTULIN in tumors was reviewed in this paper.

Abstract:
Objective To investigate the solubility and stability of Tetrodotoxin (TTX) in different solvents, and the effect of temperature and pH on its stability. Method Solutions of TTX in different matrices were prepared. Their concentrations at different temperatures and pH buffers were determined by high performance liquid chromatography and their solubility and stability were analyzed and calculated. Result TTX was most soluble at pH 3.5 and its solubility decreased as the pH increased. TTX degraded most rapidly under strong alkali conditions, with complete degradation after 20 min of reaction at 0.1 mol/L sodium hydroxide and 70 ℃. The stability test results similarly demonstrated that TTX was least stable under alkaline conditions. In a PBS buffered solution at 37 ℃, pH 7.4, TTX concentration began to decrease consistently at 1~10h, with a degradation rate of 88.07±0.27% after 28 days. Conclusion TTX is readily soluble in acidic aqueous solutions at pH 3.5 and almost insoluble in alkaline aqueous solutions. Its stability is closely related to the temperature and pH of the medium. It is more stable in acidic aqueous solutions and easily degrades under alkaline conditions, and its degradation process could be accelerated by increasing temperature.

Abstract:
Objective To explore the fluctuation characteristics of long-term doctor's order workload in pharmacy intravenous admixture services (PIVAS) and build a daily workload fluctuation prediction model and provide reference for the adjustment of PIVAS work mode. Methods Daily workload data of long-term doctor’s orders from PIVAS in the East Campus of Zhongshan Hospital affiliated to Fudan University from July 2020 to June 2021 were selected , and the time series analysis method was used to analyze the workload fluctuation characteristics and a prediction model was established. The accuracy of the model was verified by fitting parameters and prediction results. Results The fluctuation of PIVAS long-term doctor's daily workload data had the characteristics of periodicity, short-term slow rise and irregular variation. The Winters multiplier model was used to fit the series with R2 = 0.777, the significance value of Ljung-Box statistic value (P value) was 0.060, and the mean absolute error percentage between the fitted and actual values was 4.45%, indicating that the model fitting accuracy was high. The average relative deviation between the predicted and actual results was 3.81%, indicating that the model prediction was effective. Conclusion The model constructed in this study could be used for the analysis and prediction of long-term doctor's orders workload of PIVAS. However, because the workload of doctor's orders has fluctuations such as periodicity and irregular changes, it is necessary to adjust the working model according to the fluctuation characteristics of the workload and the prediction results to ensure the efficient operation of PIVAS.
