Objective To explore the efficacy and safety of recombinant human anti-severe acute respiratory syn-drome coronavirus 2(anti-SARS-CoV-2)monoclonal antibody injection(F61 injection)in the treatment of patients with coronavirus disease 2019(COVID-19)combined with renal damage.Methods Patients with COVID-19 and renal damage who visited the PLA General Hospital from January to February 2023 were selected.Subjects were randomly divided into two groups.Control group was treated with conventional anti-COVID-19 therapy,while trial group was treated with conventional anti-COVID-19 therapy combined with F61 injection.A 15-day follow-up was conducted after drug administration.Clinical symptoms,laboratory tests,electrocardiogram,and chest CT of pa-tients were performed to analyze the efficacy and safety of F61 injection.Results Twelve subjects(7 in trial group and 5 in control group)were included in study.Neither group had any clinical progression or death cases.The ave-rage time for negative conversion of nucleic acid of SARS-CoV-2 in control group and trial group were 3.2 days and 1.57 days(P=0.046),respectively.The scores of COVID-19 related target symptom in the trial group on the 3rd and 5th day after medication were both lower than those of the control group(both P＜0.05).According to the clinical staging and World Health Organization 10-point graded disease progression scale,both groups of subjects improved but didn't show statistical differences(P＞0.05).For safety,trial group didn't present any infusion-re-lated adverse event.Subjects in both groups demonstrated varying degrees of elevated blood glucose,elevated urine glucose,elevated urobilinogen,positive urine casts,and cardiac arrhythmia,but the differences were not statistica-lly significant(all P＞0.05).Conclusion F61 injection has initially demonstrated safety and clinical benefit in trea-ting patients with COVID-19 combined with renal damage.As the domestically produced drug,it has good clinical accessibility and may provide more options for clinical practice.

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 factors influencing the occurrence of poor surgical incision healing after gynecologic open surgery in elderly patients, and to construct a risk prediction model.Methods:A retrospective cohort study was conducted to collect perioperative data from 255 elderly patients(age ≥60 years at the time of surgery)who underwent gynecologic open abdominal surgery in Beijing Hospital from September 2021 to September 2023, and the patients were divided into 204 cases of the well-healed group and 51 cases of the poorly healed group according to the healing of their abdominal incision conditions, and all the included samples were randomly split into the training set of 179 cases and the validation set of 76 cases according to a ratio of 7∶3.Risk factors for poor incision healing were screened using univariate analysis and multifactorial Logistic regression analysis, and a column-line diagram model was constructed.The predictive value of the model was examined using the receiver operating characteristic(ROC)curve, the internal validation of the model was performed using the Bootstrap method, the clinical application value of the model was evaluated by plotting the calibration curve, and the predictive performance of the model was compared by calculating the net reclassification index(NRI)and the integrated discriminant improvement index(IDI).Results:The results of univariate analysis showed that age, body mass index(BMI), preoperative abdominal wall thickness, intraoperative bleeding, preoperative albumin, postoperative minimum albumin, ascites, nature of the disease, and perioperative albumin supplementation were correlated with abdominal incision healing(all P<0.05).Multifactorial Logistic regression analysis showed that perioperative albumin supplementation( OR=0.07, 95% CI: 0.01-0.44, P=0.008), age( OR=1.28, 95% CI: 1.12-1.52, P<0.001), preoperative abdominal wall thickness( OR=5.75, 95% CI: 2.81-15.74, P<0.001), and postoperative minimum albumin( OR=0.82, 95% CI: 0.69-0.97, P=0.017)were the influencing factors of abdominal incision healing.Plotting the ROC curves of the column-line graphical model showed that the area under the curve(AUC)for the training set and the internal validation set were 0.982(95% CI: 0.967-0.997)and 0.961(95% CI: 0.906-1.000), respectively.The model was validated using the Bootstrap self-sampling method, and the calibration curve showed that the model predicted well with good calibration, and NRI and IDI indicated that the predictive value of the four combined was higher than that of a single index for poor incision healing. Conclusions:The prediction model established in this study(including 4 indicators of age, preoperative abdominal wall thickness, perioperative albumin supplementation, and postoperative minimum albumin)has been statistically tested and internally validated to predict the risk of poorly healed abdominal incisions in elderly women in the perioperative period, facilitating timely clinical adjustment of treatment for high-risk patients.

OBJECTIVE: To evaluate the efficacy and safety of Jianpi Jieyu Decoction (JJD) for treating patients with mild-to-moderate depression of Xin (Heart)-Pi (Spleen) deficiency (XPD) syndrome. METHODS: In this multi-center, randomized, controlled study, 140 patients with mild-to-moderate depression of XPD syndrome were included from Xiyuan Hospital of China Academy of Chinese Medical Sciences and Botou Hospital of Traditional Chinese Medicine from December 2017 to December 2019. They were randomly divided into JJD group and paroxetine group by using a random number table, with 70 cases in each group. The patients in the JJD group were given JJD one dose per day (twice daily at morning and evening, 100 mL each time), and the patients in the paroxetine group were given paroxetine (10 mg/d in week 1; 20 mg/d in weeks 2-6), both orally administration for a total of 6 weeks. The primary outcome was the change of 17-item Hamilton Depression Rating Scale (HAMD-17) score at week 6 from baseline. The secondary outcomes included the Hamilton Anxiety Scale (HAMA) score, Traditional Chinese Medicine Symptom Scale (TCMSS), and Clinlcal Global Impression (CGI) scores at the 2nd, 4th, and 6th weekends of treatment, HAMD-17 response (defined as a reduction in score of >50%) and HAMD-17 remission (defined as a score of ⩽7) at the end of the 6th week of treatment. Adverse events (AEs) were also recorded. RESULTS: From baseline to week 6, the HAMD-17 scores decreased 10.2 ± 4.0 and 9.1 ± 4.9 points in the JJD and paroxetine groups, respectively (P=0.689). The HAMD-17 response occurred in 60% of patients in the JJD group and in 50% of those in the paroxetine group (P=0.292); HAMD-17 remission occurred in 45.7% and 30% of patients, respectively (P=0.128). The differences of CGI scores at the 6th week were not statistically significant (P>0.05). There were significant differences in HAMD-17 scores between the two groups at 2nd and 4th week (P=0.001 and P=0.014). The HAMA scores declined 8.1 ± 3.0 and 6.9 ± 4.3 points from baseline to week 6 in the JJD and paroxetine groups, respectively (P=0.905 between groups). At 4th week of treatment, there was a significant difference in HAMA between the two groups (P=0.037). TCMSS decreased 11.4 ± 5.1, and 10.1 ± 6.8 points in the JJD and paroxetine groups, respectively (P=0.080 between groups). At the 6th week, the incidence of AEs in the JJD group was significantly lower than that in the paroxetine group (7.14% vs. 22.86%, P<0.05). CONCLUSION Compared with paroxetine, JJD was associated with a significantly lower incidence of AEs in patients with mild-to-moderate depression of XPD syndrome, with no difference in efficacy at 6 weeks.

The treatment of refractory Glaucoma is a difficult problem in clinical ophthalmology. For refractory glaucoma patients with hyphema, shallow anterior chamber, anterior conglutination of peripheral chamber angle, corneal endothelium dystrophy or decompensated, at present, there is no effective treatment. In order to solve this problem, a new type posterior integral glaucoma valve with IOP control device was designed using medical titanium alloy, and the valve model was established by Abaqus software, and the stiffness and preload of the valve were analyzed by finite element method. The results showed that the opening and closing of the valve were controlled automatically by the pressure difference between the front and back of the valve, and the opening and flow rate of the valve increase dynamically with the increase of intraocular pressure, and finally reached the set ideal IOP value of steady state.

Objective: To analyze the prevalence of dry and wet age-related macular degeneration (AMD) in patients with diabetes, hypertension and hyperlipidemia, and to analyze the risk factors for AMD. Methods: A population-based cross-sectional epidemiologic study was conducted involving 14,440 individuals. We assessed the prevalence of dry and wet AMD in diabetic and non-diabetic subjects and analyzed the risk factors for AMD. Results: The prevalence of wet AMD in diabetic and non-diabetic patients was 0.3% and 0.5%, respectively, and the prevalence of dry AMD was 17% and 16.4%, respectively. The prevalence of wet AMD in healthy, hypertensive, hyperlipidemic, and hypertensive/hyperlipidemic populations was 0.5%, 0.3%, 0.2%, and 0.7%, respectively. The prevalence of dry AMD in healthy, hypertensive, hyperlipidemic, and hypertensive/hyperlipidemic populations was 16.6%, 16.2%, 15.2%, and 17.2%, respectively. Age, sex, body mass index, and use of hypoglycemic drugs or lowering blood pressure drugs were corrected in the risk factor analysis of AMD. Diabetes, diabetes/hypertension, diabetes/hyperlipidemia, and diabetes/hypertension/hyperlipidemia were analyzed. None of the factors analyzed in the current study increased the risk for the onset of AMD. Conclusion There was no significant difference in the prevalence of wet and dry AMD among diabetic and non-diabetic subjects. Similarly, there was no significant difference in the prevalence of wet and dry AMD among subjects with hypertension and hyperlipidemia. Diabetes co-existing with hypertension and hyperlipidemia were not shown to be risk factors for the onset of dry AMD.

ObjectiveTo analyze the differential components in water extract of Chuanxiong Rhizoma before and after processing with wine， and to explore the molecular mechanism of Chuanxiong Rhizoma processed with wine in enhancing anti-cerebral ischemia injury. MethodUltra high performance liquid chromatography tandem quadrupole orbitrap high resolution mass spectrometry （UHPLC-Q-Orbitrap HRMS） was used to qualitatively analyze the main chemical components in water extract of Chuanxiong Rhizoma based on the spectral information of compound， comparison of reference substance and references. The chemical pattern recognition method was used to screen the differential components of Chuanxiong Rhizoma before and after processing. Based on these differential components， the potential targets of differential components were predicted by online databases， and the related targets of cerebral ischemia were searched. Cytoscape 3.6.0 was used to establish the network diagram of differential components-action targets-diseases of Chuanxiong Rhizoma processed with wine. The protein-protein interaction （PPI） network of intersection targets was constructed by STRING 11.5. The potential targets of differential components against cerebral ischemia were analyzed by Gene Ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） enrichment analysis through DAVID 6.8. At the same time， the chemical compounds with high relative content and increased peak area after wine processing were docked with their corresponding targets to verify the mechanism of enhanced effect after wine processing. ResultA total of 71 chemical components were identified from Chuanxiong Rhizoma， 34 differential components and 603 potential targets were screened out. At the same time， a total of 769 disease targets and 60 intersection targets were obtained. Seven key targets were identified through PPI network analysis， including JUN， signal transducer and activator of transcription 3 （STAT3）， mitogen-activated protein kinase 3 （MAPK3）， interleukin-1β （IL-1β）， vascular endothelial growth factor A （VEGFA）， Caspase-3 （CASP3） and mtrix metalloproteinase 9 （MMP9）. Tumor necrosis factor （TNF） signaling pathway was the main differential signaling pathway. The results of molecular docking showed that differential components （senkyunolide K， senkyunolide F， 3-n-butylphthalide， Z，Z′-6，8′，7，3′-diligustilide， ferulic acid and Z-ligustilide） and corresponding targets had good binding activities. ConclusionThe synergistic mechanism of Chuanxiong Rhizoma processed with wine may be related to the enhanced inhibitory effect of inflammatory reaction.

BACKGROUND: Prospective analyses have yet to identify a consistent relationship between sleep duration and the incidence of gastrointestinal (GI) cancers. The effect of changes in sleep duration on GI cancer incidence has scarcely been studied. Therefore, we aimed to examine the association between baseline sleep duration and annual changes in sleep duration and GI cancer risk in a large population-based cohort study. METHODS: A total of 123,495 participants with baseline information and 83,511 participants with annual changes in sleep duration information were prospectively observed from 2006 to 2015 for cancer incidence. Cox proportional-hazards models were used to calculate hazard ratios (HRs) and their confidence intervals (CIs) for GI cancers according to sleep duration and annual changes in sleep duration. RESULTS: In baseline sleep duration analyses, short sleep duration (≤5 h) was significantly associated with a lower risk of GI cancer in females (HR: 0.31, 95% CI: 0.10-0.90), and a linear relationship between baseline sleep duration and GI cancer was observed (P = 0.010), especially in males and in the >50-year-old group. In the annual changes in sleep duration analyses, with stable category (0 to -15 min/year) as the control group, decreased sleep duration (≤-15 min/year) was significantly associated with the development of GI cancer (HR: 1.29; 95% CI: 1.04-1.61), especially in the >50-year-old group (HR: 1.32; 95% CI: 1.01-1.71), and increased sleep duration (>0 min/year) was significantly associated with GI cancer in females (HR: 2.89; 95% CI: 1.14-7.30). CONCLUSIONS Both sleep duration and annual changes in sleep duration were associated with the incidence of GI cancer.

1-deoxy-D-xylulose-5-phosphate synthase2(DXS2) is the first key enzyme of the MEP pathway,which plays an important role in terpene biosynthesis of plants. According to the data of Swertia mussotii transcriptome, DXS2 gene(Gen Bank number MH535905) was cloned and named as Sm DXS2. The bioinformatics results showed that Sm DXS2 has no intron,with a 2 145 bp open reading frame encoding a polypeptide of 714 amino acids. They are belonging to 20 kinds of amino acids,and the most abundant amino acids include Ala,Gly and Trp. The predicted protein molecular weight was 76. 91 k Da and its theoretical isoelectric point(p I) was6. 5,which belonging to a hydrophilic protein. α-Helix and loop were the major motifs of predicted secondary structure of DXS2. The three function domains are TPP＿superfamily,Transket＿pyr＿ superfamily and Transketolase＿C superfamily,respectively. The Sm DXS2 protein shared high identity with other DXS2 proteins of plants. Phylogenetic analysis showed that Sm DXS2 protein is grouped with the gentian DXS2 protein. The recombinant protein of Sm DXS2 gene in Escherichia coli was approximately 92. 00 k Da(containing sumo-His tag protein 13 k Da),which was consistent with the anticipated size.This work will provide a foundation for further functional research of Sm DXS2 protein and increasing the product of iridoid compound by genetic engineering in S. mussotii.
