Sphingomyelin phosphodiesterase 3 (SMPD3) encodes neutral sphingomyelinase 2 (nSMase2), which plays an important role in tumor development as a key enzyme regulating cell growth variation and inducing apoptosis with the important messenger molecule ceramide. On one hand, the common epigenetic alteration of SMPD3 methylation mediates carcinogenesis through the disruption of gene expression by regulating cell proliferation, differentiation, and apoptosis. Meanwhile, SMPD3 also induces apoptosis and cell cycle arrest in tumor cells through its hydrolysis products. On the other hand, SMPD3 is also closely related to pro-cancer processes such as exosome secretion, inflammatory response, and tumor cell proliferation. In this paper, the biological action of SMPD3 in tumor diseases was reviewed to enhance the understanding of the role of SMPD3 in the development of different tumors and provide broader ideas for basic research and clinical diagnosis and treatment of tumor diseases.

Gei Herba is a traditional folk herbal medicine with a variety of functions such as replenishing Qi and invigorating spleen, tonifying blood and nourishing Yin, moistening lung and resolving phlegm, activating blood and alleviating edema, moving Qi, and activating blood. The reports about the pharmacological effects of this herbal medicine have been increasing in recent years. By reviewing the ancient and modern literature about Gei Herba, we systematically organized the name, original plants, nature, taste, and functions of this herbal medicine, and summarized the modern pharmacological studies and clinical applications of Gei Herba in cardiovascular and cerebrovascular diseases. Gei Herba was first recorded in the name of "Dijiao" in the Geng Xin Yu Ce(《庚辛玉册》) written in the Ming Dynasty. It is derived from Geum japonicum var. chinense (Rosaceae) and sometimes confused with Adina rubella (Rubiaceae). This medicine had numerous synonyms in the local materia medica books. Gei Herba is widely distributed and harvested in summer and autumn, with the dried whole grass used as medicine. The historical records of the nature, taste, meridian tropism, main functions, and indications of Gei Herba are not consistent. It is generally believed that Gei Herba is pungent, bitter, sweet, cool, and has tropism to the liver, spleen, and lung meridians. Based on the effects of tonifying Qi, activating blood, and nourishing Yin, modern pharmacological studies have reported that the extracts of Gei Herba and the tannin phenolic acid compounds and triterpenoids isolated from Gei Herba have therapeutic effects on cardiovascular and cerebrovascular diseases such as hypertension, myocardial ischemia, cerebral ischemia, and vascular dementia. This study provides a reference for discovering the clinical advantages of Gei Herba and developing new drugs.

Despite exciting achievements with some malignancies, immunotherapy for hypoimmunogenic cancers, especially glioblastoma (GBM), remains a formidable clinical challenge. Poor immunogenicity and deficient immune infiltrates are two major limitations to an effective cancer-specific immune response. Herein, we propose that an injectable signal-amplifying nanocomposite/hydrogel system consisting of granulocyte-macrophage colony-stimulating factor and imiquimod-loaded antigen-capturing nanoparticles can simultaneously amplify the chemotactic signal of antigen-presenting cells and the "danger" signal of GBM. We demonstrated the feasibility of this strategy in two scenarios of GBM. In the first scenario, we showed that this simultaneous amplification system, in conjunction with local chemotherapy, enhanced both the immunogenicity and immune infiltrates in a recurrent GBM model; thus, ultimately making a cold GBM hot and suppressing postoperative relapse. Encouraged by excellent efficacy, we further exploited this signal-amplifying system to improve the efficiency of vaccine lysate in the treatment of refractory multiple GBM, a disease with limited clinical treatment options. In general, this biomaterial-based immune signal amplification system represents a unique approach to restore GBM-specific immunity and may provide a beneficial preliminary treatment for other clinically refractory malignancies.

Objective:To explore the clinical risk factors of post-transplantation diabetes mellitus (PTDM) and establish a risk prediction model in kidney recipients.Methods:The clinical data and postoperative bedside measurements of blood glucose (BG) were retrospectively reviewed for 305 renal transplant recipients at First Affiliated Hospital of Zhejiang University School of Medicine from October 2018 to August 2019.According to whether or not PTDM occurred, they were assigned into two groups of PTDM (n=34) and non-PTDM (n=271). Risk factors were screened through single/multi-factor Logistic regression and PTDM prediction model was established.Results:The incidence rate of PTDM was 11.15%(34/305). Logistic regression analysis indicated that deceased donor, age ≥40 years, female, pre-hemoglobin A1c (Pre-HbA1c) and postoperative bedside BG value ≥11.1 mmol/L were the correlated factors for the occurrence of PTDM.Among them, female ( OR=3.13, 95% CI: 1.28-7.61), Pre-HbA1c ( OR=2.05, 95% CI: 1.12-3.74) and BG ≥11.1 mmol/L at 4pm Day 2/3 post-operation ( OR=19.08, 95% CI: 4.34-83.87) were risk factors for the occurrence of PTDM, The area under the model curve was 0.86 (95% CI: 0.79-0.93) with a Jordan index of 0.65, a sensitivity of 82.8% and a specificity of 82.3%. Conclusions:Female, Pre-HbA1c and fasting BG at 4 pm Day 2/3 post-operation ≥ 11.1 mmol/L are risk factors for the occurrence of PTDM.The prediction model has a decent predictive value.It is conducive to early clinical interventions and lowering the incidence rate of PTDM.

Objective:To summarize our experience in 13 cases of intestinal autotransplantation (IATx) after resection of lesions involving the roots of mesenteric vessels.Methods:The clinical data of 13 patients undergoing IATx in Xijing hospital were retrospectively analyzed. The etiology, surgical procedure and complications were analyzed. The patients were followed up by telephone and regular evaluations.Results:All 13 cases of IATx were successfully completed. For 12 patients who were diagnosed with tumors involving the mesenteric roots, the tumors were removed for cure intent avoiding massive intestinal resection. Pancreaticoduodenectomy was carried out simultaneously in 11 cases. The postoperative complication rate was 85% (11/13). The autograft was resected in 1 patient on the 1st postoperative day due to necrosis from mesenteric thrombosis, leading to short bowel syndrome. One-year survival was 69% (9/13). Among 4 deaths, 1 patient died of liver metastasis, and another died of liver and lung metastases. Five patients were alive 2 years postoperatively.Conclusion:IATx while-technically challenging, avoiding short small bowel syndrome in properly selected patients after resection of lesions especially benign ones involving the roots of mesenteric vessels that were traditionally considered to be "unresectable".
