Application of PARP inhibitors combined with immune checkpoint inhibitors in ovarian cancer.

The advent of polyadenosine diphosphate ribose polymerase inhibitors (PARPi) has brought about significant changes in the field of ovarian cancer treatment. However, in 2022, Rucaparib, Olaparib, and Niraparib, had their marketing approval revoked for third-line and subsequent therapies due to an increased potential for adverse events. Consequently, the exploration of new treatment modalities remains imperative. Recently, the integration of PARPi with immune checkpoint inhibitors (ICIs) has emerged as a potential remedy option within the context of ovarian cancer. This article offers a comprehensive examination of the mechanisms and applications of PARPi and ICIs in the treatment of ovarian cancer. It synthesizes the existing evidence supporting their combined use and discusses key considerations that merit attention in ongoing development efforts.

Cost-Effectiveness of Domestic PD-1 Inhibitor Camrelizumab Combined With Chemotherapy in the First-Line Treatment of Advanced Nonsquamous Non-Small-Cell Lung Cancer in China.

Objective: Camrelizumab is the first domestic PD-1inhibitor approved to be combined with chemotherapy as a first-line therapy for advanced nonsquamous non-small-cell lung cancer (NSCLC) in China. The purpose of this study was to determine whether using camrelizumab in the first-line setting is cost-effective in China when compared with traditional chemotherapy or the imported PD-1inhibitor pembrolizumab. Material and Methods: A Markov model was built to simulate 3-week patient transitions over a 30-year horizon from the perspective of the Chinese healthcare system. Health states included stable disease, first progression, second progression, and death. A direct comparison between first-line camrelizumab in combination with pemetrexed and carboplatin (CPC) and pemetrexed plus carboplatin (PC) was performed by calculating transition probabilities from the CameL trial. An indirect comparison between first-line CPC and pembrolizumab in combination with pemetrexed and platinum (PPP) was performed by calculating transition probabilities using a network meta-analysis. Costs in the Chinese setting were collected from the local public database and literatures. Sensitivity analyses explored the uncertainty around model parameters. Results: In the primary analysis, first-line CPC gained an additional 0.41 quality-adjusted life-years (QALYs) with an incremental cost of $3,486 compared with PC, resulting in an incremental cost-effectiveness ratio (ICER) of $8,378 per QALY gained. In the secondary analysis, first-line PPP yielded an additional 0.10 QALYs at an incremental cost of $6,710, resulting in an ICER of $65,563 per QALY gained. Conclusion: For Chinese patients with advanced nonsquamous NSCLC without targetable genetic aberrations, our primary analysis results supported first-line CPC as a cost-effective treatment compared with traditional PC chemotherapy. The findings of our secondary analysis suggested that first-line PPP would not be a cost-effective option compared with first-line CPC. This analysis provided strong evidence for promoting the widespread use of first-line CPC in China and, to some extent, stimulated the enthusiasm for the development of domestic cancer drugs.

IgG Fc binding protein (FCGBP) as a prognostic marker of low-grade glioma and its correlation analysis with immune infiltration / 细胞与分子免疫学杂志

Objective To identify the possibility of IgG Fc binding protein (FCGBP) acting as a prognostic marker of low-grade glioma (LGG) and its correlation with immune infiltration. Methods The expression of FCGBP was analyzed in pan-cancer using The Cancer Genome Atlas (TCGA), Genotypic tissue expression (GTEX), and China Glioma Genome Atlas (CGGA) database. Then, GSE15824 and GSE68848 datasets were selected for further verification. And gene expression Profile Interaction analysis (GEPIA) database and R language were used to analyze the relationship between FCGBP and survival prognosis. Metascape and GSEA were used for functional annotation and enrichment analysis. Finally, the expression of FCGBP gene in LGG immune microenvironment and its correlation with immune cells were analyzed by TIMER database. Results FCGBP was highly expressed in LGG tissues, indicating poor prognosis of LGG patients. Receiver operating characteristic (ROC) curve analysis and COX analysis showed that FCGBP was an independent risk factor for the prognosis of LGG. Moreover, Gene Ontology (GO) demonstrated that FCGBP was involved in cell metabolism, localization, positive, and negative regulation of biological processes, as well as biological adhesion, response to viral and microbial stimulation, and inflammation. GSEA pathway enrichment analysis showed that FCGBP was significantly correlated with Janus kinase/signal transducer and activator of transcription (JAK/STAT) pathway, Toll-like receptor (TLR) pathway, chemokine pathway, and P53 pathway. In addition, FCGBP expression was positively correlated with the expression of most immune cells in the immune microenvironment of LGG. Conclusion The high expression of FCGBP in LGG is a risk factor for survival and prognosis, and it is positively correlated with the expression of immune cells.

Progress in research of prophylactic therapy in contacts of rifampicin-resistant tuberculosis patients / 中华流行病学杂志

Tuberculosis (TB) prophylactic therapy for latent infection, which can reduce the risk for the development of active TB, is an important measure in TB control. China recommends prophylactic therapy for latent tuberculosis infection (LTBI) in some key populations to reduce the risk for TB. Contacts of patients with multi-drug and rifampicin-resistant TB (MDR/RR-TB) are at high risk for the infection with drug-resistant pathogen, however, no unified prophylactic therapy regimen has been recommended for LTBI due to exposure to MDR/RR-TB patients. This paper summarizes the current MDR/RR-TB prophylactic therapy regimen and its protection effect based on the results of the retrieval of literature, guidelines, expert consensus and technical specifications to provide reference for the prevention and control of LTBI.

Objective • To investigate the effect of medium frequency electrical stimulation on the expression of neurotrophin-3(NT-3) in the mandibular protrusion of SD rats. Methods • Sixty male SD rats were randomly divided into three groups (n=20): blank control group, conditioned control group (treated with functional appliance, but without medium frequency electrical stimulation) and experimental group (treated with functional appliance and medium frequency electrical stimulation). Five rats in each group were sacrificed on the 3rd, 7th, 14th and 21st day to prepare the samples of masseter muscle. Immunohistochemistry and quantitative real-time PCR methods were used to detect the protein and mRNA expressions of NT-3 in the masseter muscle of rats. Results • The protein and mRNA expressions of NT-3 were increased firstly and then decreased in the conditioned control group and the experimental group, compared with those in the blank control group. Moreover, the protein and mRNA expressions of NT-3 in the conditioned control group were still higher than those in the blank control group on the 21st day (both P<0.05), while the protein and mRNA expressions of NT-3 in the experimental group almost returned to the normal level on the 21st day. Conclusion • Medium frequency electrical stimulation may accelerate the rate of neuromuscular reconstruction and shorten the time of functional orthopedic therapy in rats.

Objective:To investigation of efficacy and safety of Ticagrelor vs.Clopidogrel as add-on to a common therapy of Aspirin in elderly patients with acute ST-segment elevation myocardial infarction(STEMI)and undergoing percutaneous coronary intervention(PCI). Methods:A total of 208 elderly patients with STEMI and receiving PCI were divided into the Ticagrelor group(n=103, receiving Ticagrelor 180 mg, followed by 90 mg twice a day)and the Clopidogrel group(n=105, receiving Clopidogrel 600 mg, followed by 75 mg/d)as add-on to a common therapy of Aspirin(300 mg before operation, followed by 100 mg/d). Both groups were treated for 12 months.Coronary artery blood flow, platelet aggregation rate, left ventricular ejection fraction(LVEF), left ventricular end-diastolic diameter(LVEDD), bleeding events and major adverse cardiovascular events(MACE)after PCI were compared between the two groups.Results:The TIMI(thrombolysis in myocardial infarction)grading after PCI was better in the Ticagrelor group than in the Clopidogrel group( Z=2.58, P=0.010). The incidence of no-reflow or slow blood flow was lower in the Ticagrelor group than in the Clopidogrel group(6.8% or 7/103 vs. 19.1% or 20/105, χ2=6.91, P=0.009). The variance analysis of repeated data showed that the platelet aggregation rate was decreased along with time in both groups( Ftime=87.54, P<0.001). The decrement of platelet aggregation rate was higher in the Ticagrelor group than in the Clopidogrel group( Ftime×group=6.16, P<0.001). The overall level of platelet aggregation was lower in the Ticagrelor group than in the Clopidogrel group( Fgroup=17.84, P<0.001). The platelet aggregation rates at 1 hour, 1 day and 3 days after operation were lower in the Ticagrelor group than in the Clopidogrel group( t=14.39, 13.19 and 6.53, respectively, P<0.001). LVEF was increased in both groups after PCI( t=7.46 and 4.33, all P<0.001), while LVEF was higher in the ticagrelor group than in the clopidogrel group( t=4.28, P<0.001). LVEDD was decreased in both groups after PCI( t=9.36 and 6.47, all P<0.001), while LVEDD was lower in the ticagrelor group than in the clopidogrel group( t=4.38, P<0.001). There were no significant differences in the incidences of hemorrhage and MACE between the two groups( χ2=0.91 and 2.32, all P>0.05). Conclusions:Ticagrelor has good anti-platelet aggregation effect in the treatment of STEMI after PCI in the elderly, and it reduces the incidences of no-or slow reflow, improves cardiac function.

Mechanistic evaluation of gastro-protective effects of KangFuXinYe on indomethacin-induced gastric damage in rats / 中国天然药物

KangFuXinYe (KFX), the ethanol extract of the dried whole body of Periplaneta americana, is a well-known important Chinese medicine preparation that has been used to treat digestive diseases such as gastric ulcers for many years in China. However, its therapeutic effect and mechanism are not yet well understood. Thus, the aim of this study was to investigate the gastro-protective effects of KangFuXinYe (KFX) in indomethacin-induced gastric damage. Rats were randomly divided into six groups as follows: control, treated with indomethacin (35 mg·kg), different dosages of KFX (2.57, 5.14 and 10.28 mL·kg, respectively) plus indomethacin, and sucralfate (1.71 mL·kg) plus indomethacin. After treatment, rat serum, stomach and gastric homogenates were collected for biochemical tests and examination of histopathology firstly. Rat serum was further used for metabolomics analysis to research possible mechanisms. Our results showed that KFX treatment alleviated indomethacin-induced histopathologic damage in rat gastric mucosa. Meanwhile, its treatment significantly increased cyclooxygenase-1 (COX-1), prostaglandin E (PGE) and epidermal growth factor (EGF) levels in rat serum and gastric mucosa. Moreover, KFX decreased cyclooxygenase-2 (COX-2) and interleukin-6 (IL-6) levels. Nine metabolites were identified which intensities significantly changed in gastric damage rats, including 5-hydroxyindoleacetic acid, indoxylsulfuric acid, indolelactic acid, 4-hydroxyindole, pantothenic acid, isobutyryl carnitine, 3-methyl-2-oxovaleric acid, sphingosine 1-phosphate, and indometacin. These metabolic deviations came to closer to normal levels after KFX intervention. The results indicate that KFX (10.28 mL·kg) exerts protective effects on indomethacin-induced gastric damage by possible mechanisms of action (regulating tryptophan metabolism, protecting the mitochondria, and adjusting lipid metabolism, and reducing excessive indomethacin).

Effect of Traditional Chinese Medicine and Western Medicine Therapy on Gestational Diabetes Mellitus / 中国实验方剂学杂志

In recent years, as the level of economic life has improved, the incidence of gestational diabetes mellitus has increased year by year. Gestational diabetes mellitus (GDM) has been a serious threat to maternal and newborn health. The pathogenesis of gestational diabetes is not very clear, and may be closely associated with insulin resistance, genetic susceptibility, inflammatory response, metabolic disorders. According to the gestational diabetes diagnostic standard,24-28 weeks pregnant women keep an empty stomach over 8 h, taken 75 g oral glucose directly, and then receive the oral glucose tolerance test. GDM is diagnosed as fasting blood-glucose> 5.1 mmol · L-1,1-hour postprandial blood glucose>10.0 mmol · L-1,and 2-hour postprandial blood glucose>8.5 mmol · L-1. Western medicine treatment is mainly based on diet, exercise, drugs, education, monitoring and insulin therapy according to blood glucose. Meanwhile, GDM is a type of diabetes in traditional Chinese medicine. GDM is prevented and treated with diets and traditional method sports and Chinese herbs. Therefore, integrated Chinese and western medicine therapy can maximize the curative effect, reduce the incidence of gestational diabetes mellitus, and effectively improve the adverse outcome and prognosis of patients with gestational diabetes mellitus from mother to child.
