ObjectivePolygoni Multiflori Radix is a commonly used tonic traditional Chinese medicine （TCM） in clinical practice， but liver injury has often been reported in recent years. Some related preparations containing Polygoni Multiflori Radix have been reported by the National Medical Products Administration many times for the risk of liver injury. This has caused extensive discussion on the potential toxicity of TCM in China and abroad， which has limited the clinical use of Polygoni Multiflori Radix to some extent. To understand the adverse reactions of Polygoni Multiflori Radix， the safe and rational use of Polygoni Multiflori Radix in clinical practice was discussed. MethodsThe pharmacovigilance thought of modern Chinese medicine and the TCM pharmacovigilance system framework of ''identification of poison， use of poison， anti-poison， and detoxification'' were employed to mine the relevant toxicity records， usage and dosage， processing compatibility， and contraindication of taking Polygoni Multiflori Radix in ancient books. The drug safety information of Polygoni Multiflori Radix was summarized by comparing with modern reports. ResultsA total of 74 ancient books related to Polygoni Multiflori Radix were included， suggesting that the toxicity of Polygoni Multiflori Radix was recognized in ancient times. The main chemical components of Polygoni Multiflori Radix had both efficacy and toxicity， and the adverse reactions may be related to long-term use， excessive use， and individual differences. The results showed that the toxic components of Polygoni Multiflori Radix could be reduced by peeling， steaming with black beans， and processing without iron tools. The toxic effects of Polygoni Multiflori Radix could be reduced by the compatibility of Polygoni Multiflori Radix with Poria， Psoraleae Fructus， and Cistanches Herba. ConclusionReasonable dosage， standard processing， correct compatibility， and syndrome differentiation are the key points to standardize the use of Polygoni Multiflori Radix and reduce the incidence of adverse reactions. Clinically， the toxicity classification of TCM should be strengthened， and the susceptible population should be prioritized. The detection indicators and early warning mechanisms should be improved， and precise drug dosage and course of treatment should be guaranteed. These measures can ensure the safe use of Polygoni Multiflori Radix.

Liver diseases are a group of complex clinical conditions caused by various factors and can lead to hepatocyte damage and liver dysfunction， posing a serious threat to human health. The cyclic GMP-AMP synthase （cGAS）-stimulator of interferon genes （STING） signaling pathway plays a key regulatory role in the course of liver diseases and is involved in the development， progression， and treatment of various diseases such as viral hepatitis， nonalcoholic fatty liver disease， liver fibrosis， and liver cancer. This article reviews the regulatory mechanisms of the cGAS-STING signaling pathway in processes such as inflammation， autophagy， antiviral response， and oxidative stress， analyzes its molecular function in liver diseases， and explores its application prospect as a potential target for the treatment of liver diseases， in order to provide a theoretical basis for developing novel therapeutic strategies for liver diseases.

Epigenomic imbalance drives abnormal transcriptional processes,promoting the onset and progression of cancer.Although defective gene regulation generally affects carcinogenesis and tumor suppression networks,tumor immunogenicity and immune cells involved in antitumor responses may also be affected by epigenomic changes,which may have significant implications for the development and application of epigenetic therapy,cancer immunotherapy,and their combinations.Herein,we focus on the impact of epigenetic regulation on tumor immune cell function and the role of key abnormal epigenetic processes,DNA methylation,histone post-translational modification,and chromatin structure in tumor immunogenicity,and introduce these epigenetic research methods.We emphasize the value of small-molecule inhibitors of epigenetic modulators in enhancing antitumor immune responses and discuss the challenges of developing treatment plans that combine epigenetic therapy and immuno-therapy through the complex interaction between cancer epigenetics and cancer immunology.

OBJECTIVE To provide reference for the adjustment of antibiotic treatment regimens， identification of adverse reactions， and individualized pharmaceutical care for melioidosis sepsis （MS）. METHODS Clinical pharmacists participated in the intensive and eradicating therapeutic processes for an MS patient by using blood concentration and gene detection. Based on the literature， antibiotic treatment regimens of MS were adjusted by determining the blood concentrations of β-lactam and trimethoprim/ sulfamethoxazole （TMP/SMZ） and calculating PK/PD parameters. The causes of adverse drug reactions were analyzed and addressed by detecting drug-related gene polymorphisms through high-throughput sequencing. RESULTS Clinical pharmacists used blood concentration and genetic testing methods to propose adjustments to imipenem-cilastatin sodium dosage and analyze the causes of various adverse drug reactions. PK/PD targets were calculated by measuring the blood concentrations of β-lactam and TMP/SMZ. Clinical pharmacists explained to clinical doctors the compliance status of patients with melioidosis in sepsis and non- sepsis stages through reviewing guidelines and literature； the results of blood concentration and genetic test were used to analyze the correlation of neurotoxicity of MS patients with B14） IMP cmin， and it was found that nephrotoxicity was not related to the cmax of TMP/SMZ， but to the patient’s water intake. After whole-process antibiotic treatment， the patient’s condition improved and was discharged， and the adverse reactions were effectively treated. CONCLUSIONS Clinical pharmacists use blood concentration and genetic tests to assist clinicians in formulating MS treatment regimens， and provide whole-course pharmaceutical care for a MS patient. This method has improved the safety and effectiveness of clinical drug therapy.

Progesterone is currently the first-line drug for clinical treatment and prevention of threatened abortion and habitual abortion. However， due to its special chemical structure， its solubility is low， which limits its clinical application. Therefore， the new technology and new dosage form of progesterone solubilization preparation is an important direction of its research and development. In this paper， the research progress of progesterone solubilization preparation technology in recent years is reviewed. It is found that the water solubility of progesterone can be enhanced by solid dispersion technology， inclusion technology， micronization， nanocrystallization （ including nanosuspensions， polymer micelles， nanoparticles， etc. ）， liposome technology， self- emulsification， cocrystal technology， and 3D printing. Eight technologies are used to increase the solubility of progesterone， improve its bioavailability and reduce its toxic and side effects， to serve the clinic better.

In recent years, organ donation and transplantation have entered a stage of steady development in China. Nevertheless, the shortage of transplant organs and the contradiction between supply and demand of organs are still the bottlenecks to achieve the strategy of "self-sufficiency in organ transplantation" advocated by the World Health Organization (WHO). The key reasons for donor loss described in the "critical pathway of organ donation" defined by the WHO include the identification and referral of potential donors and the maintenance and repair of organs. Smooth development, high efficiency and high-quality development of organ donation cannot be achieved without the support of intensive care medicine, which are highly associated with the cognition, recognition and participation of intensive care unit(ICU) staff. In this article, research progress in ICU staff’s cognition, attitude and willingness for organ donation were reviewed and relevant influencing factors were discussed, aiming to offer targeted suggestions on how to resolve these difficulties.

OBJECTIVE To prepare progesterone-2-chloro-4-nitroaniline cocrystal （CNA） so as to improve the solubility of progesterone and primarily evaluate the safety of the progesterone cocrystal in vivo. METHODS Using progesterone as the main body and CNA as the ligand， progesterone-CNA cocrystal was prepared with solvent evaporation method. The cocrystal was characterized by X-ray single crystal diffraction， X-ray powder diffraction （XRPD）， differential scanning calorimetry （DSC） and Fourier transform infrared spectroscopy （IR）. The dissolution rate of cocrystal was compared with those of progesterone and physical mixture. Forty-eight female KM mice were randomly divided into normal group （phosphate buffer containing 0.1% dimethyl sulfoxide）， progesterone group （16 mg/kg）， CNA group （9 mg/kg）， progesterone-CNA cocrystal low-dose， medium- dose and high-dose groups （6， 12.5， 25 mg/kg）， with 8 mice in each group. They were given relevant medicine/solvent intramuscularly， once a day， for consecutive 14 d. The safety of cocrystal was evaluated primarily by determining/observing the changes in body weight， organ index， tissue morphology， blood routine indicators， and liver and kidney function indicators. RESULTS The new crystal structure in the X-ray single crystal diffraction results， the new characteristic peak in the XRPD pattern， the change of melting point in the DSC results， and the change of the characteristic peak position in the range of 3 500- 2 750 cm－1 and 1 700-1 250 cm－1 in the infrared spectrum all Δ 基金项目国家重点研发计划项目（No.2022YFC3502100） indicated that progesterone-CNA cocrystal was successfully ＊第一作者 硕士研究生 。研究方向 ：药物制备技术与工艺 。 prepared， and the dissolution rate of cocrystal was more than E-mail：SWB_1221@163.com # 通信作者教授，硕士生导师，博士。研究方向：药物制备技术与 twice that of the progesterone raw material drug.

Compared with normal group， uterine indexes of mice in progesterone group and progesterone-CNA cocrystal groups were significantly increased （P＞0.05）， and endometrium was also thickened； there was no statistical difference in the changes of body mass， liver and kidney function， liver index， kidney index， the number of leukocyte， lymphocyte and neutrophil in routine blood test among those groups （P＞0.05）， and the morphology of liver and kidney tissue has also no significant difference. However， the number of plasma red blood cells in the progesterone group decreased significantly （P＜0.05）， and there was no statistical significance in the number difference of red blood cells among progesterone-CNA cocrystal groups （P＞0.05）. CONCLUSIONS The progesterone-CNA cocrystal is successfully prepared with good safety in vivo， which significantly improve the solubility of progesterone.

Objective:To investigate the current status of activation in patients with spinal cord injury and analyze its influencing factors.Methods:Using the convenient sampling method, a total of 127 patients from Department of Spinal Surgery in the Third Affiliated Hospital of Soochow University from October 2020 to August 2021 were selected as the research objects. The patients were investigated by General Data Questionnaire, Patient Activation Measure (PAM) , General Self-Efficacy Scale (GSES) , Connor-Davidson Resilience Scale (CD-RISC) , Social Support Rating Scale (SSRS) and Hospital Anxiety and Depression Scale (HADS) . Multiple linear hierarchical regression analysis was used to investigate the influencing factors of activation in patients with spinal cord injury.Results:A total of 127 questionnaires were sent out, and 122 were effectively received, with the effective recovery of 96.1%. The score of activation in patients with spinal cord injury was (54.71±7.23) . Regression analysis showed that injury site, mental resilience and social support were the main influencing factors of activation ( P<0.05) , and the global regression model explained 50.0% of the variation in activation in patients with spinal cord injury. Conclusions:Patients with spinal cord injury generally have moderate levels of activation during hospitalization. The activation of patients with spinal cord injury is a positive psychosocial resource, and rehabilitation nurses should pay more attention to it, and improve the mental resilience and social support of patients, so as to further enhance the activation of patients.

Objective:To provide evidence for optimizing the screening strategy for gastric cancer (GC), we evaluated the risk of incident GC for individuals with different precancerous gastric lesions in a prospective cohort study.Methods:Based on the National Upper Gastrointestinal Cancer Early Detection Program launched in Linqu, Shandong, a high-risk area of gastric cancer in China, we included a total of 14 087 subjects diagnosed with different gastric lesions stages by endoscopic screening from 2012 to 2018. Study subjects were prospectively followed up until December 31, 2019. The incidence of GC during the follow-up was ascertained by repeated endoscopic examinations, cancer, death registry reports, and active follow-up of study subjects and was confirmed by reviewing medical records extracted from the hospital information management system. The Poisson regression model was applied to calculate the relative risk ( RR) and 95% CI for GC occurrence among subjects with different gastric lesions. Results:Among 14 087 subjects with different gastric lesions as determined by their first endoscopic examination in 2012-2018, 7 608 (54.00%) had a global diagnosis of superficial gastritis (SG), 2 848 (20.22%) had chronic atrophic gastritis (CAG), 3 103 (22.03%) had intestinal metaplasia (IM), and 520 (3.69%) had low-grade intestinal neoplasia (LGIN). During the follow-up, 109 subjects were diagnosed with GC, including 63 with high-grade intestinal neoplasia (HGIN) and 46 with invasive GC. Compared to subjects having normal gastric mucosa or SG, those with CAG ( RR=3.85, 95% CI: 2.04-7.28), IM ( RR=5.18, 95% CI: 2.79-9.60), and LGIN ( RR=19.08, 95% CI: 9.97-36.53) had significantly increased risk of progression to GC. Individuals with these gastric lesions had an elevated risk of developing HGIN and invasive GC. For subjects with LGIN, the RR was 22.96 (95% CI: 9.71-54.27) for developing HGIN and 14.64 (95% CI: 5.37-39.93) for developing invasive GC. Subgroup analyses found that all age group subjects with LGIN diagnosed during the initial endoscopic examination had a significantly increased risk of developing the GC. Conclusions:Our large-scale prospective study on a high-risk area of GC showed that most residents aged 40-69 years had gastric lesions of different stages. Subjects with more advanced gastric lesions had a significantly increased risk of progression to GC.
