This study aimed to explore key quality control factors that affected the prognosis of intensive care unit (ICU) patients in Chinese mainland over six years (2015-2020). The data for this study were from 31 provincial and municipal hospitals (3425 hospital ICUs) and included 2 110 685 ICU patients, for a total of 27 607 376 ICU hospitalization days. We found that 15 initially established quality control indicators were good predictors of patient prognosis, including percentage of ICU patients out of all inpatients (%), percentage of ICU bed occupancy of total inpatient bed occupancy (%), percentage of all ICU inpatients with an APACHE II score ⩾15 (%), three-hour (surviving sepsis campaign) SSC bundle compliance (%), six-hour SSC bundle compliance (%), rate of microbe detection before antibiotics (%), percentage of drug deep venous thrombosis (DVT) prophylaxis (%), percentage of unplanned endotracheal extubations (%), percentage of patients reintubated within 48 hours (%), unplanned transfers to the ICU (%), 48-h ICU readmission rate (%), ventilator associated pneumonia (VAP) (per 1000 ventilator days), catheter related blood stream infection (CRBSI) (per 1000 catheter days), catheter-associated urinary tract infections (CAUTI) (per 1000 catheter days), in-hospital mortality (%). When exploratory factor analysis was applied, the 15 indicators were divided into 6 core elements that varied in weight regarding quality evaluation: nosocomial infection management (21.35%), compliance with the Surviving Sepsis Campaign guidelines (17.97%), ICU resources (17.46%), airway management (15.53%), prevention of deep-vein thrombosis (14.07%), and severity of patient condition (13.61%). Based on the different weights of the core elements associated with the 15 indicators, we developed an integrated quality scoring system defined as F score=21.35%xnosocomial infection management + 17.97%xcompliance with SSC guidelines + 17.46%×ICU resources + 15.53%×airway management + 14.07%×DVT prevention + 13.61%×severity of patient condition. This evidence-based quality scoring system will help in assessing the key elements of quality management and establish a foundation for further optimization of the quality control indicator system.

In the context of Pharma 4.0, the design tools that support the pharmaceutical Quality by Design(QbD) are iterating fast toward intelligent or smart design. The conventional development methods for traditional Chinese medicine(TCM) preparations have the limitations such as over dependence on experience, low dimensions for the designed experiment parameters, poor compatibility between the process and equipment, and high trial-and-error cost during process scale-up. Therefore, this paper innovatively proposed the intelligent co-design involving material, process, and equipment for manufacturing high-quality TCM preparations, and introduced the design philosophy, targets, tools, and applications with TCM oral solid dosage(OSD) as an example. In terms of design philosophy, the pharmaceutical design tetrahedron composed of critical material attributes, critical process parameters, critical equipment attributes, and critical quality attributes was developed. The design targets were put forward based on the product performance classification system. The design tools involve a design platform that contains several modules, such a as the iTCM material database, the processing route classification system, the system modeling and simulation, and reliability-based optimization. The roles of different modules in obtaining essential and universal design knowledge of the key common manufacturing units were introduced. At last, the applications of the co-design methodology involving material, process, and equipment in the high shear wet granulation process development and the improvement of the dissolving or dispersion capability of TCM formula granules are illustrated. The research on advanced pharmaceutical design theory and methodology will help enhance the efficiency and reliability of drug development, improve the product quality, and promote the innovation of high-end TCM products across the industry.

Objective To screen differentially expressed genes (DEGs) associated with chronic schistosomiasis japonica-induced hepatic fibrosis and analyze their functions. Methods The dataset of gene expression profiles of patients with chronic schistosomiasis japonica-induced hepatic fibrosis was downloaded from the Gene Expression Omnibus (GEO) database, and DEGs were screened using R package. The biological functions of DEGs were characterized using Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses. In addition, the protein-protein interaction (PPI) network of DEGs was created to screen the hub genes. Results A total of 62 DEGs were identified, including 12 down-regulated genes and 50 up-regulated genes. GO enrichment analysis showed that DEGs were mainly enriched in 116 biological processes, including fatty acid, sulfur compound, acyl-coenzyme A and thioester metabolism; 19 cellular components, including mitochondrial matrix, outer mitochondrial membrane and organelle outer membrane; and 7 molecular functions, including insulin-like growth factor binding and oxidoreductase activity. KEGG pathway enrichment analysis that the DEGs were significantly enriched in phosphatidylinositol-3-kinase/serine/threonine protein kinase (PI3K/Akt), mitogen-activated protein kinase (MAPK), calcium metabolism and cyclic adenosine monophosphate (cAMP) signaling. PPI network analysis identified six hub genes involved in the development of chronic schistosomiasis japonica-induced hepatic fibrosis, including ACACA, ACSL1, GPAM, THRSP, PLIN1 and DGAT2, and ACSL1, ACACA and PLIN1 were the top 3 hub genes. Conclusions ACSL1, ACACA and PLIN1 may be the hub genes associated with the development of chronic schistosomiasis japonica-induced hepatic fibrosis, and abnormal lipid metabolism mediated by these DEGs may play an important role in the development of chronic schistosomiasis japonica-induced hepatic fibrosis.

Objective: Systematically summarize the research progress of clinical trials of gastric cancer oncology drugs and the overview of marketed drugs in China from 2012 to 2021, providing data and decision-making evidence for relevant departments. Methods: Based on the registration database of the drug clinical trial registration and information disclosure platform of Food and Drug Administration of China and the data query system of domestic and imported drugs, the information on gastric cancer drug clinical trials, investigational drugs and marketed drugs from January 1, 2012 to December 31, 2021 was analyzed, and the differences between Chinese and foreign enterprises in terms of trial scope, trial phase, treatment lines and drug type, effect and mechanism studies were compared. Results: A total of 114 drug clinical trials related to gastric tumor were registered in China from 2012 to 2021, accounting for 3.7% (114/3 041) of all anticancer drug clinical trials in the same period, the registration number showed a significant growth rate after 2016 and reached its peak with 32 trials in 2020. Among them, 85 (74.6%, 85/114) trials were initiated by Chinese pharmaceutical enterprise. Compared with foreign pharmaceutical enterprise, Chinese pharmaceutical enterprise had higher rates of phase I trials (35.3% vs 6.9%, P=0.001), but the rate of international multicenter trials (11.9% vs 67.9%, P<0.001) was relatively low. There were 76 different drugs involved in relevant clinical trials, of which 65 (85.5%) were targeted drugs. For targeted drugs, HER2 is the most common one (14 types), followed by PD-1 and multi-target VEGER. In the past ten years, 3 of 4 marketed drugs for gastric cancer treatment were domestic and included in the national medical insurance directory. Conclusions: From 2012 to 2021, China has made some progress in drug research and development for gastric carcinoma. However, compared with the serious disease burden, it is still insufficient. Targeted strengthening of research and development of investment in many aspects of gastric cancer drugs, such as new target discovery, matured target excavating, combination drug development and early line therapy promotion, is the key work in the future, especially for domestic companies.

During the coronavirus disease (COVID-19) epidemic, there have been concerns about the impact of vaccines on people's fertility, including the fertility of those who are currently preparing for pregnancy and those who might become pregnant in future. However, there is still a lack of research on the effect of the COVID-19 vaccine on male fertility, and it is not surprising that couples and donors have concerns regarding vaccination. In this study, a retrospective cohort study was conducted to examine semen quality before and after receipt of the inactivated COVID-19 vaccine. There were no statistically significant changes in semen parameters (volume, sperm concentration, progressive motility, and total progressive motile count) after two doses of vaccine (all P > 0.05). In summary, our study updates the most recent studies on the effects of the COVID-19 vaccine on male fertility, and the information from this study could be used to guide fertility recommendations for assisted reproductive technology (ART) patients and donors.

Through consulting the ancient herbs, medical books and modern literature, this paper made textual research on the name, origin, producing area, quality evaluation, collection and processing of medicinal materials of Sang (Mori Folium, Mori Cortex, Mori Ramulus, Mori Fructus) in famous classical formulas, in order to provide a basis for the development of famous classical formulas containing medicinal materials of Sang. According to the research, Mori Folium and Mori Cortex were first used as medicines in Shengnong Bencaojing , Mori Ramulus was first used as medicine in Jinxiaofang, and Mori Fructus was first used as medicine in Xinxiu Bencao. Before the Tang dynasty, there were Nyusang and Shansang. Since Tang dynasty, there were many sources of medicinal materials of Sang, including Baisang (Morus alba), Jisang (M. australis), Shansang (M. mongolica), etc. According to textual research, the mainstream varieties were M. australis, M. alba and their cultivated varieties. In modern times, according to the relevant information and the Chinese Pharmacopoeia, M. alba is the original base. In ancient times, the origin of mulberry changed with the development of sericulture, mulberry has been widely planted since the Song dynasty. In the Ming and Qing dynasties, mulberry has been planted most in Jiangsu and Zhejiang. In modern times, they are mainly produced in Jiangsu, Zhejiang, Anhui, Hunan and other places. In recent years, due to the related policies and strategies such as "moving silkworms from east to west", the center of silkworm breeding has gradually transferred to the west. As for the quality evaluation and harvesting and processing of mulberry medicinal materials, Most of the ancient and modern records of Mori Folium are the same. They are harvested after frost, and dried after removing impurities. The quality is better when the leaves are large and thick, yellowish green, holding prickly hands and undergoing frost. The harvesting period of Mori Cortex is slightly different in ancient and modern records. Ancient books record that it can be harvested all the year round, but in modern times, it is mostly harvested from late autumn to the next spring. The processing methods include removing soil and fibrous roots, scraping off yellow-brown rough skin, peeling off white skin and drying in the sun. The quality is better when they are white, thick, flexible, free of rough skin and full of powder. There are few records about the collection, processing and quality evaluation of Mori Ramulus and Mori Fructus in ancient Chinese herbal books. According to modern literature, Mori Ramulus is usually collected in late spring and early summer, with leaves removed, slightly dried, sliced while fresh, and dried in the sun. The best quality of Mori Ramulus is fine and tender with the yellow and white section. Mori Fructus is harvested from April to June when the fruit turns red, and dried in the sun, or slightly steamed and dried in the sun, and it is better to be big, dark purple, oily and thick. There are many processing methods of mulberry medicinal materials. Ancient books record stir frying, baking, burning and steaming of Mori Folium, in modern times, there is honey-roasted method, but most of them are used as raw products. In ancient materia medica, Mori Cortex has firing method, baking method, stir-frying method, honey-fried method, etc. In modern times, there are stir-fried and honey-fried methods, and most of them are used as raw products. Ancient books record that Mori Ramulus has cutting and frying methods, while modern ones have cutting, frying, wine-processed and bran-processed methods. Processing methods of Mori Fructus are consistent in ancient and modern times, and they are mostly dried after being cleaned or steamed. Based on the research results, it is suggested that M. alba should be selected as mulberry medicinal materials in the famous classical formulas, and appropriate medicinal parts and processing methods can be selected according to the indications of the famous classical formulas.
