Gardeniae Fructus, a traditional Chinese medicine, has significant pharmacological activities such as clearing heat and detoxifying, promoting bile secretion and protecting liver injury. It is widely used in clinical practice for treating conditions like fever-induced restlessness, damp-heat jaundice, dysuria with pain, and fire-toxin sores. Gardeniae Fructus has been included in "list of items that are both food and medicine", so it is also used as an ingredient in food and health products. However, recent toxicological studies have shown that Gardeniae Fructus has certain potential hepatotoxicity, and its improper use may pose a risk. Therefore, it is necessary to clarify the dual regulatory effects and their scientific connotations of Gardeniae Fructus on efficacy and toxicity. Based on the current progress in clinical, pharmacological and toxicological researches, this paper will discuss the characteristics and possible mechanisms of the dual effects of efficacy and toxicity of Gardeniae Fructus, and propose thoughts on the rational clinical use and scientific supervision of Gardeniae Fructus.

Objective:To analyze ultrasonographic manifestations and genetic etiology of nine fetuses with 7q11.23 duplication syndrome.Methods:Ultrasonographic finding, pregnancy outcome and follow-up of nine fetuses detected at the Prenatal Diagnosis Center of the Third Affiliated Hospital of Zhengzhou University from January 2017 to December 2021 were retrospectively analyzed.Results:The fetuses were found to harbor a duplication in the 7q11.23 region by chromosomal microarray analysis (CMA). Among these, five had shown ventriculomegaly, including four syndromic and one non-syndromic. For the remainders, one had ventricular septal defect and mild tricuspid regurgitation, one had echogenic intracardiac focus, whilst another two were normal. Five couples had accepted parental verification, and the results confirmed that the 7q11.23 duplication carried by their fetuses were de novo in origin. Following genetic counseling, seven couples had opted to terminate their pregnancies. Two fetuses were delivered at full term, and follow-up had found no abnormalities. Conclusion:Prenatal ultrasonographic manifestations of fetuses with 7q11.23 duplication syndrome are variable. CMA can provide assistance for their diagnosis and genetic counseling.

Objective To explore the effects of dihydromyricetin on the proliferation,apoptosis,and invasion of endometrial cancer(EC)cells and its possible mechanisms.Methods Ishikawa cells in the logarithmic growth phase were taken and divided into the control group,20 μmol/L dihydromyricetin intervention group,40 μmol/L dihydromyricetin intervention group,and 80 μmol/L dihydromyricetin intervention group,which were treated with different final concentrations of dihydromyricetin(0 μmol/L,20 μmol/L,40 μmol/L,80 μmol/L).Then,CCK-8 assay and flow cytometry were used to detect the effects of dihydromyricetin on the cell proliferation and apoptosis.Transwell experiment was used to detect the effect of dihydromyricetin on the cell invasion.qRT-PCR and Western blot were used to detect the effects of dihydromyricetin on the cell expression of miR-21 and PTEN.Results Compared with the control group,the cell proliferation inhibition rate and apoptosis rate in the dihydromyricetin intervention group were significantly increased(P<0.05),and gradually increased with the increase of dihydromyricetin concentration(P<0.05).Compared with the control group,the numbers of migration and invasion cells in the dihydromyricetin intervention group were significantly decreased(P<0.05),and gradually decreased with the increase of dihydromyricetin concentration(P<0.05).Compared with the control group,the cell expression of miR-21 in the dihydromyricetin intervention group was significantly decreased(P<0.05),and gradually decreased with the increase of dihydromyricetin concentration(P<0.05),the expression levels of PTEN mRNA and protein were significantly increased(P<0.05),and gradually increased with the increase of dihydromyricetin concentration(P<0.05).Conclusion Dihydromyricetin can inhibit the growth and metastasis of EC cells,and the inhibitory effect is positively correlated with its concentration.The mechanism may be related to the effect of dihydromyricetin on the miR-21/PTEN signaling pathway of EC cells.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

{L-End}Objective To study the intervention effect of hydrogen on early inflammation in a rat silicosis model and its mechanism. {L-End}Methods Wistar rats of specific pathogen free were randomly divided into the control group, model group, tetrandrine group, hydrogen group and combined intervention group, with 10 rats in each group. The rats in the last four groups were treated with a dose of l.00 mL silica suspension with a mass concentration of 50.0 g/L by a one-time non-exposed tracheal method. The rats in the control group were given 0.9% sodium chloride solution in equal volume. After 24 hours of dust exposure, rats of the tetrandrine group were given 30 mg/kg body mass tetrandrine by gavage daily, rats of the hydrogen group were given 66.6% hydrogen inhalation continuously for four hours daily, rats of the combined intervention group were given the same interventions as the rats in the tetrandrine group and the hydrogen group, rats in the control group and model group were given 0.9% sodium chloride solution in equal volume by gavage. After 14 days of treatment, the lung coefficient of rats was determined, and lung histopathology was performed. The level of malondialdehyde in serum was detected by colorimetry. The level of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) in serum were detected by enzyme-linked immunosorbent assay. The relative expression of nucleotide-binding oligomerization domain-like receptor thermal protein domain associated protein 3 (NLRP3), nuclear factor-κB (NF-κB) p65, NF-κB phosphorylated p65 (NF-κB p-p65), cysteinyl aspartate specific proteinase1 (Caspase1) and apoptosis-associated speck-like protein containing a CARD (ASC) in serum were detected in lung tissues by Western blot. The relative expression of NLRP3 and NF-κB p65 in lung tissues were detected by immunohistochemistry. {L-End}Results The result of pulmonary histopathology showed that the model group had obvious alveolar rupture and fusion, interstitial lymphocyte and macrophage infiltration, and alveolar wall thickening, collagen fibre deposition, and mild fibrotic hyperplasia, compared with the control group. The pathological outcomes of lung tissues in the three treated groups were alleviated compared with the model group, and the alveolar structure was more complete and the alveolar wall was thinner and the fewer collagen fibres in the rats of combined intervention group, compared with tetrandrine group and hydrogen group. The lung coefficient and Szapiel score of rats of the tetrandrine group, hydrogen group and combined intervention group were lower than those of the model group (all P<0.05). The levels of serum malondialdehyde, TNF-α and IL-1β in lung tissues, and the relative expression of NLRP3, NF-κB p65, NF-κB P-p65, Caspase1 and ASC in lung tissues increased in the model group, compared with the control group (all P<0.05). The indexes above decreased in the three treated groups than those in the model group (all P<0.05). The indexes above decreased in the combined intervention group than those in the tetrandrine group and hydrogen group (all P<0.05), except for the level of malondialdehyde in serum and the relative expression of NF-κB p-p65 in lung tissue. {L-End}Conclusion Hydrogen can intervene the early inflammation of silicosis through NF-κB/ NLRP3 signaling pathway.

Aim To investigate the effect of Lulong Zaisheng Decoction II on chemotherapy-induced bone marrow suppression in nude mice bearing colorectal cancer. Methods Male BALB/C nude mice were inoculated with human colon cancer cell HT-29 under the armpit. The tumor bearing nude mice were randomly divided into five groups: control group, chemotherapy group, positive drug group, Lulong Zaisheng Decoction II groups with high and low doses. The mice were given drugs by gavage once a day for 10 consecutive days. From the fourth day of the experiment, except for the control group, the nude mice were intraperitoneally injected with 5-FU at dose of 25 mg • kg

Objective To investigate the treatment outcomes,prognosis,and risk factors of treatment failure of peritoneal dialysis associated peritonitis (PDAP) caused by Klebsiella pneumoniae,and thus provide clinical evidence for the prevention and treatment of this disease. Methods The clinical data of PDAP patients at four peritoneal dialysis centers from January 1,2014 to December 31,2019 were collected retrospectively.The treatment outcomes and prognosis were compared between the patients with PDAP caused by Klebsiella.pneumoniae and that caused by Escherichia coli.Kaplan-Meier method was employed to establish the survival curve of technical failure,and multivariate Logistic regression to analyze the risk factors of the treatment failure of PADP caused by Klebsiella pneumoniae. Results In the 4 peritoneal dialysis centers,1034 cases of PDAP occurred in 586 patients from 2014 to 2019,including 21 cases caused by Klebsiella pneumoniae and 98 cases caused by Escherichia coli.The incidence of Klebsiella pneumoniae caused PDAP was 0.0048 times per patient per year on average,ranging from 0.0024 to 0.0124 times per patient per year during 2014-2019.According to the Kaplan-Meier survival curve,the technical failure rate of Klebsiella pneumoniae caused PDAP was higher than that of Escherichia coli caused PDAP (P=0.022).The multivariate Logistic regression model showed that long-term dialysis was an independent risk factor for the treatment failure of Klebsiella pneumoniae caused PDAP (OR=1.082,95%CI=1.011-1.158,P=0.023).Klebsiella pneumoniae was highly sensitive to amikacin,meropenem,imipenem,piperacillin,and cefotetan,and it was highly resistant to ampicillin (81.82%),cefazolin (53.33%),tetracycline (50.00%),cefotaxime (43.75%),and chloramphenicol (42.86%). Conclusion The PDAP caused by Klebsiella pneumoniae had worse prognosis than that caused by Escherichia coli,and long-term dialysis was an independent risk factor for the treatment failure of Klebsiella pneumoniae caused PDAP.

Objective To analyze the genetic subtypes of human immunodeficiency virus (HIV) and the prevalence of pretreatment drug resistance in the newly reported HIV-infected men in Guangxi. Methods The stratified random sampling method was employed to select the newly reported HIV-infected men aged≥50 years old in 14 cities of Guangxi from January to June in 2020.The pol gene of HIV-1 was amplified by nested reverse transcription polymerase chain reaction and then sequenced.The mutation sites associated with drug resistance and the degree of drug resistance were then analyzed. Results A total of 615 HIV-infected men were included in the study.The genetic subtypes of CRF01_AE,CRF07_BC,and CRF08_BC accounted for 57.4% (353/615),17.1% (105/615),and 22.4% (138/615),respectively.The mutations associated with the resistance to nucleoside reverse transcriptase inhibitors (NRTI),non-nucleoside reverse transcriptase inhibitors (NNRTI),and protease inhibitors occurred in 8 (1.3%),18 (2.9%),and 0 patients,respectively.M184V (0.7%) and K103N (1.8%) were the mutations with the highest occurrence rates for the resistance to NRTIs and NNRTIs,respectively.Twenty-two (3.6%) patients were resistant to at least one type of inhibitors.Specifically,4 (0.7%),14 (2.3%),4 (0.7%),and 0 patients were resistant to NRTIs,NNRTIs,both NRTIs and NNRTIs,and protease inhibitors,respectively.The pretreatment resistance to NNRTIs had much higher frequency than that to NRTIs (2.9% vs.1.3%;χ²=3.929,P=0.047).The prevalence of pretreatment resistance to lamivudine,zidovudine,tenofovir,abacavir,rilpivirine,efavirenz,nevirapine,and lopinavir/ritonavir was 0.8%, 0.3%, 0.7%, 1.0%, 1.3%, 2.8%, 2.9%, and 0, respectively. Conclusions CRF01_AE,CRF07_BC,and CRF08_BC are the three major strains of HIV-infected men≥50 years old newly reported in Guangxi,2020,and the pretreatment drug resistance demonstrates low prevalence.

Objective: To analyze the status of statins use and low-density lipoprotein cholesterol (LDL-C) management in patients with atrial fibrillation (AF) and very high/high risk of atherosclerotic cardiovascular disease (ASCVD) from Chinese Atrial Fibrillation Registry (CAFR). Methods: A total of 9 119 patients with AF were recruited in CAFR between January 1, 2015 to December 31, 2018, patients at very high and high risk of ASCVD were included in this study. Demographics, medical history, cardiovascular risk factors, and laboratory test results were collected. In patients with very high-risk, a threshold of 1.8 mmol/L was used as LDL-C management target and in patients with high risk, a threshold of 2.6 mmol/L was used as LDL-C management target. Statins use and LDL-C compliance rate were analyzed, multiple regression analysis was performed to explore the influencing factors of statins use. Results: 3 833 patients were selected (1 912 (21.0%) in very high risk of ASCVD group and 1 921 (21.1%) in high risk of ASCVD group). The proportion of patients with very high and high risk of ASCVD taking statins was 60.2% (1 151/1 912) and 38.6% (741/1 921), respectively. Attainment rate of LDL-C management target in patients with very high and high risk were 26.7% (511/1 912) and 36.4% (700/1 921), respectively. Conclusion: The proportion of statins use and attainment rate of LDL-C management target are low in AF patients with very high and high risk of ASCVD in this cohort. The comprehensive management in AF patients should be further strengthened, especially the primary prevention of cardiovascular disease in AF patients with very high and high risk of ASCVD.
