OBJECTIVE To optimize the freeze-drying process for sheep placenta slices. METHODS An orthogonal test design was used with pre-freezing time， drying time and drying temperature as indicators to screen for the optimal freeze-drying process for sheep placenta slices. The peptide content， ethanol-soluble extract content， and freeze-drying rate of sheep placenta were used as indicators，the analytic hierarchy process-criteria importance through intercriteria correlation （AHP-CRITIC） method was employed to determine the weight of each indicator and calculate the comprehensive score， which was verified using the technique for order of preference by similarity to ideal solution （TOPSIS） model. RESULTS The optimal preparation process was found to be the pre-freezing time of 2 hours， the drying time of 16 hours， and the drying temperature of 30 °C. The average values of peptide content， ethanol-soluble extract content， and freeze-drying rate for three batches of samples were 5.883 mg/mL， 27.1%， and 95.77%， respectively； the comprehensive scores of three batches were 96.42， 99.18 and 99.58， with RSD of 1.75%. CONCLUSIONS This study successfully optimized the freeze-drying process for sheep placenta slices， which can provide a reference for the quality standard setting and industrial production of this type of slice.

Objective:To analyze the effects of SARS-CoV-2 infection and vaccination on virus mutation.Methods:The whole genome sequencing sequences of 2 659 local SARS-CoV-2 specimens from Jiangsu Province in 2023 were selected for analysis, and relevant information such as demographic and clinical characteristics were collected, and the effects of infection and vaccination on the genome-wide mutation rate and S gene′s selective pressure of the virus were analyzed by univariate and multivariate linear regression models.Results:The average age of these infected patients was 55.0 (31.0, 74.0) years, 1 150 cases (43.2%) in the age group of ≥60 years, 1 367 cases (51.4%) were males, 2 044 cases (76.9%) had a history of COVID-19 vaccination, and 1 629 cases (61.3%) had the first-time infection. The clinical symptoms of the infected patients were mainly mild, with a total of 2434 cases (91.5%), and 29 cases (1.1%) with severe symptoms or more. The average substitution rate of SARS-CoV-2 was 9.69 (9.38, 9.98)×10 -4 subs/site/year, and the dN/dS value of the S gene was 6.08 (5.56, 8.66), which was significantly greater than that of 1 ( P<0.001), indicating positive selection. The result of univariate and multivariate linear regression model analysis showed that the SARS-CoV-2 substitution rate was higher in those with vaccination history and reinfection, aged 20-30 years, ≥60 years, and the SARS-CoV-2 substitution rate was lower in males with moderate clinical symptoms and severe disease and above. Those with a history of vaccination and reinfection, aged 50-60 years old, ≥60 years old have smaller S gene dN/dS. Conclusions:Under the immune pressure exerted by vaccination and infection, the genome-wide mutation of SARS-COV-2 accelerated, but the non-synonymous mutation rate of the S gene decreased. The mechanism causing these phenomena needs further study.

The gut microbiota plays a pivotal role in the immunomodulatory and protumorigenic microenviron-ment of colorectal cancer(CRC).However,the effect of ginsenoside Rk3(Rk3)on CRC and gut microbiota remains unclear.Therefore,the purpose of this study is to explore the potential effect of Rk3 on CRC from the perspective of gut microbiota and immune regulation.Our results reveal that treatment with Rk3 significantly suppresses the formation of colon tumors,repairs intestinal barrier damage,and regulates the gut microbiota imbalance caused by CRC,including enrichment of probiotics such as Akkermansia muciniphila and Barnesiella intestinihominis,and clearance of pathogenic Desulfovibrio.Subsequent metabolomics data demonstrate that Rk3 can modulate the metabolism of amino acids and bile acids,particularly by upregulating glutamine,which has the potential to regulate the immune response.Furthermore,we elucidate the regulatory effects of Rk3 on chemokines and inflammatory factors associated with group 3 innate lymphoid cells(ILC3s)and T helper 17(Th17)signaling pathways,which inhibits the hyperactivation of the Janus kinase-signal transducer and activator of transcription 3(JAK-STAT3)signaling pathway.These results indicate that Rk3 modulates gut microbiota,regulates ILC3s immune response,and inhibits the JAK-STAT3 signaling pathway to suppress the development of colon tumors.More importantly,the results of fecal microbiota transplantation suggest that the inhibitory effect of Rk3 on colon tumors and its regulation of ILC3 immune responses are mediated by the gut microbiota.In summary,these findings emphasize that Rk3 can be utilized as a regulator of the gut microbiota for the prevention and treatment of CRC.

Aim To investigate the effects of Cartham-us tinctorius L.extract(CTLE)on oxidative stress,lipid metabolism,and apoptosis levels of mice with al-cohol-induced liver injury and its mechanism of action.Methods The mouse model of alcohol-associated liver disease was established by chronic alcohol feeding and acute alcohol gavage.Mice were randomly divided into four groups.During the modeling period,the state changes of mice were observed every day,and their weight was recorded.At the end of modeling,blood and liver tissues were collected from each group of mice.The blood of mice was analyzed biochemically,and HE staining and Oil Red O staining were used to evaluate further the degree of pathological damage in the liver of mice.Quantitative real-time PCR(qPCR)and Western blot were applied to detect the mRNA and protein expression levels of p-PI3K,PI3K,p-Akt,Akt,p-mTOR,mTOR,p-FoxO1,FoxO1,p-FoxO3a,FoxO3a,p-FoxO4,FoxO4,BCL and BAX factors.Results Compared to the model group,the CTLE administration group showed improved hepatic patho-logical injury and reduced lipid deposition.The bio-chemical indexes in serum and liver,such as ALT,AST,TG,TC,and MDA levels were reduced,while GSH and SOD levels increased.Regulating the PI3K/Akt/FoxO pathway resulted in increased production of SOD,which reduced damage and apoptosis caused by reactive oxygen species(ROS).Conclusions CTLE can exert anti-oxidative stress and anti-apoptotic effects through the PI3K/Akt/FoxO pathway and attenuates alcoholic liver injury in mice,providing new ideas for the treatment of alcoholic liver disease and the develop-ment of related drugs.

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.

Objective To investigate the effects of Carthamus tinctorius L.extract(CTLE)on the levels of oxidative stress and inflammation in mice with ethanol-induced alcoholic liver disease and its mechanism of action.Methods SPF-grade C57BL/6 male mice were randomly divided into four groups:control group,model group,low-CTLE group(50 mg·kg-1),and high-CTLE group(100 mg·kg-1).The control group was given Lieber-Decarli liquid diet,and the other groups were given Lieber-Decarli alcohol diet to construct a chronic alcoholic liver injury model in mice.Serum and liver tissues of mice were collected and serum biochemical indexes of mice were detected.HE and oil red O staining were applied to observe pathological changes in mouse liver tissues.Real-time fluorescence quantitative PCR and Western Blot were used to detect the mRNA and protein expression levels of Keap1/Nrf2 and STAT3/NF-κB pathway-related factors.Results Compared with the model group,the ALT,AST,LDL-C,and MDA levels were significantly reduced(P＜0.05,P＜0.01),while the levels of HDL-C,SOD,and GSH were increased dramatically in the administered group(P＜0.05,P＜0.01),which indicated that CTLE has specific protective and antioxidant effects on alcoholic liver injury in mice.HE staining and oil red O staining showed that the hepatic lesions and lipid deposition of mice were ameliorated.It enhances the antioxidant and anti-inflammatory effects of the body by activating the mRNA and protein expression levels of antioxidant factors related to the Keap1/Nrf2 pathway and inhibiting the mRNA and protein expression levels of inflammatory factors related to STAT3/NF-κB pathway(P＜0.05,P＜0.01).Conclusion It was shown that CTLE could exert anti-oxidative stress and anti-inflammatory effects through regulating Keap1/Nrf2 and STAT3/NF-κB signaling pathways to attenuate alcoholic liver injury in mice.This study may provide a new idea for the treatment of alcoholic liver disease and the subsequent study of molecular mechanisms.

BACKGROUND: LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer. METHODS: We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels. RESULTS: On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]). CONCLUSION: LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile. TRIAL REGISTRATION ClinicalTrials.gov, NCT04563936.

Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.
