This study applied the grading of recommendations assessment, development and evaluation(GRADE) system and the integrated evidence chain-based effectiveness evaluation of traditional Chinese medicine(Eff-iEC) to evaluate the evidence for 12 commonly used Chinese patent medicines for the treatment of osteoporosis, which are frequently recommended in guidelines or expert consensuses. The results showed that Xianling Gubao Capsules/Tablets were rated as C(low-level evidence) according to the GRADE system, and as BA~+B~+(intermediate evidence) according to the Eff-iEC system. Jintiange Capsules were rated as C(low-level evidence) by the GRADE system, and as AA~+B(high-level evidence) by the Eff-iEC system. Gushukang Granules/Capsules were rated as C(low-level evidence) by GRADE system, and as BA~+B~+(intermediate evidence) by Eff-iEC system. Zuogui Pills were rated as C(low-level evidence) by GRADE system, and as AA~(++)B~+(high-level evidence) by Eff-iEC system. Qianggu Capsules were rated as D(extremely low-level evidence) by GRADE system, and as AA~+B~+(high-level evidence) by Eff-iEC system. Zhuanggu Zhitong Capsules were rated as D(extremely low-level evidence) by GRADE system, and as BA~+B(intermediate evidence) by Eff-iEC system. Jingui Shenqi Pills were rated as D(extremely low-level evidence) by GRADE system, and as AA~+B(high-level evidence) by Eff-iEC system. Quanduzhong Capsules were rated as D(extremely low-level evidence) by GRADE system, and as AD~+B~+(low-level evidence) by Eff-iEC system. Epimedium Total Flavones Capsules were rated as D(extremely low-level evidence) by GRADE system, and as AAB~+(high-level evidence) by Eff-iEC system. Yougui Pills were rated as D(extremely low-level evidence) by GRADE system, and as AA~(++)B~(+ )(high-level evidence) by Eff-iEC system. Qigu Capsules were rated as D(extremely low-level evidence) by GRADE system, and as BB~+B(intermediate evidence) by Eff-iEC system. Liuwei Dihuang Pills were rated as C(low-level evidence) by GRADE system, and as AA~(++)B~+(high-level evidence) by Eff-iEC system. Overall, the Eff-iEC system provides a more comprehensive assessment of the effectiveness evidence for traditional Chinese medicine(TCM) than the GRADE system. However, it still has certain limitations that hinder its wider promotion and application. In terms of clinical evidence evaluation, both the Eff-iEC and GRADE systems reflect that the current clinical research quality on Chinese patent medicines for the treatment of osteoporosis is generally low. High-quality clinical trials are still needed in the future to further validate clinical efficacy.

Inflammatory bowel disease (IBD) is a chronic inflammatory disorder of the gastrointestinal tract, which increases the incidence of colorectal cancer (CRC). In the pathophysiology of IBD, ubiquitination/deubiquitination plays a critical regulatory function. Josephin domain containing 2 (JOSD2), a deubiquitinating enzyme, controls cell proliferation and carcinogenesis. However, its role in IBD remains unknown. Colitis mice model developed by dextran sodium sulfate (DSS) or colon tissues from individuals with ulcerative colitis and Crohn's disease showed a significant upregulation of JOSD2 expression in the macrophages. JOSD2 deficiency exacerbated the phenotypes of DSS-induced colitis by enhancing colon inflammation. DSS-challenged mice with myeloid-specific JOSD2 deletion developed severe colitis after bone marrow transplantation. Mechanistically, JOSD2 binds to the C-terminal of inosine-5'-monophosphate dehydrogenase 2 (IMPDH2) and preferentially cleaves K63-linked polyubiquitin chains at the K134 site, suppressing IMPDH2 activity and preventing activation of nuclear factor kappa B (NF-κB) and inflammation in macrophages. It was also shown that JOSD2 knockout significantly exacerbated increased azoxymethane (AOM)/DSS-induced CRC, and AAV6-mediated JOSD2 overexpression in macrophages prevented the development of colitis in mice. These outcomes reveal a novel role for JOSD2 in colitis through deubiquitinating IMPDH2, suggesting that targeting JOSD2 is a potential strategy for treating IBD.

Hemorrhagic shock is a common clinical emergency that can aggravate cell injury after resuscitation. Astrocytes are crucial for the survival of neurons because they regulate the surrounding ionic microenvironment of neurons. Although hemorrhagic shock and resuscitation (HSR) injury can impair cognition, it remains unclear how this insult directly affects astrocytes. In this study, we established an HSR model by bleeding and re-transfusion in mice. The social interaction test and new object recognition test were applied to evaluate post-operative cognitive changes, and the results suggest that mice experience cognitive impairment following exposure to HSR. In the HSR group, the power spectral density of β and γ oscillations decreased, and the coupling of the θ oscillation phase and γ oscillation amplitude was abnormal, which indicated abnormal neuronal oscillation and cognitive impairment after HSR exposure. In brief, cognitive impairment in mice is strongly correlated with Ca²⁺ signal strength in lateral septum astrocytes following HSR.

Objectives:To investigate the effect and mechanism of mitochondrial targeting peptide SS-31 on senescence and pyroptosis of nucleus pulposus(NP)cells induced by inflammation.Methods:NP cells were isolated and cultured in vitro from 6-week-old male SD rats,and were divided into control group,lipopolysaccharide(LPS)group,and LPS+SS-31 group;And the control group of cells received no treatment,LPS group of cells were treated with 100μg/mL LPS for 24h,and LPS+SS-31 group of cells were pre-treated with SS-31 30min before LPS intervention.The levels of cellular senescence and pyroptosis were assessed in each group using β-galactosidase(SA-β-Gal)staining and westem blot(WB)assay;Transmission electron mi-croscopy and oxygen consumption rate(OCR)assay were used to analyze the mitochondrial function of NP cells in each group;The expressions of phosphorylated nuclear factor-κB-p65(p-NF-κB-p65),cyclic GMP-AMP synthase(cGAS),and interferon stimulating gene(STING)in each group were detected by WB and im-munofluorescence;Hematoxylin-eosin(HE)staining,immunohistochemistry(IHC)staining and WB assay were performed to analyze the effects of in vivo injection of SS-31 on intervertebral disc degeneration,senescence,and pyroptosis.Results:The positive SA-β-Gal staining of NP cells,expression of senescence marker pro-teins(p53,p21),and pyroptosis-related molecules(NLRP3,Caspase-1 p20)were significantly lower in the LPS+SS-31 group compared with the LPS group(P＜0.05);Transmission electron microscopy(TEM)showed that the mitochondrial swelling of NP cells was round,the matrix was translucent,and the interstitial lumen of the mitochondrial cristae was dilated in the LPS group,while the mitochondrial swelling was subsided,and the morphology of mitochondria tended to be normalized in the LPS+SS-31 group.Meanwhile,the maximum respi-ration level of NP cells was significantly enhanced in the LPS+SS-31 group compared with the LPS group(P＜0.05).The results of WB and immunofluorescence showed that LPS significantly up-regulated the expression of p-NF-κB-p65,cGAS,and STING(P＜0.05),while SS-31 pretreatment significantly inhibited the expression of p-NF-κB-p65,cGAS and STING in NP cells induced by LPS(P＜0.05).Finally,in vivo experiments con-firmed that local injection of SS-31 reduced the senescence and pyroptosis of NP cells,and alleviated the degeneration of intervertebral disc induced by annulus fibropuncture.Conclusions:SS-31 alleviates inflamma-tion-induced senescence and pyroptosis of NP cells,which is related to the inhibition of NF-κB signaling pathway and cGAS/STING signaling pathway.

Objective To investigate the clinical efficacy and safety of facilitated percutaneous coronary intervention(PCI)with half-dose recombinant staphylokinase(r-SAK)in patients with ST-segment elevation myocardial infarction(STEMI)who are expected to undergo PCI within 120 minutes.Methods From October 2021 to August 2022,a total of 200 STEMI patients in eight centers were included and randomly assigned in a 1﹕1 ratio to either r-SAK group or control group.Patients received loading doses of aspirin and ticagrelor and intravenous heparin and were randomized to receive an intravenous bolus of either 5 mg r-SAK or normal saline prior to PCI.The outcomes were set as ST-segment resolution(STR)at 60-90 minutes after PCI,the proportion and transition of pathological Q waves on the 5th day after PCI,and the proportion of high-sensitivity cardiac troponin T(hs-cTnT)peaking within 12 hours of onset.The safety outcome was major bleeding events defined as Bleeding Academic Research Consortium(BARC)≥type 3 bleeding during hospitalization.Results Compared with the control group,the r-SAK group had a higher proportion of STR≥70%within 60-90 minutes after PCI(58.3%vs.40.3%,P=0.009);a lower proportion of pathological Q waves(59.1%vs.74.1%,P=0.040);a lower rate of Q wave progression(14.8%vs.43.2%,P＜0.001);a higher rate of Q wave disappearance(12.5%vs.3.7%,P=0.027);and a higher proportion of hs-cTnT peaking within 12 hours of symptom onset[31/40(77.5%)vs.17/33(51.5%),P=0.027].Regarding the safety outcome,no significant difference in BARC≥type 3 bleeding was found between the two groups during hospitalization(P＞0.05).Conclusions For STEMI patients who were expected to undergo primary PCI within 120 minutes of symptom onset,the facilitated PCI with half-dose r-SAK significantly increased the proportion of STR≥70%at 60-90 minutes after PCI,reduced the formation of pathological Q waves,and shortened the time to peak hs-cTnT,without increasing the risk of bleeding,which should be an alternative reperfusion strategy worthy of further study.

Bovine rotavirus(BRV)is an important pathogen causing diarrhea in calves.To understand the genomic charac-teristics and genetic variations in bovine rotavirus,and to further enrich data on the biological characteristics of rotavirus,we aimed to amplify 11 gene segments of the isolated and cultured G6P[1]bovine rotavirus BLL strain,perform whole genome se-quencing,and analyze the molecular characteristics.MEGA7.0 and DNAMAN software were used for homology and typing a-nalysis,and the whole genome phylogenetic tree was constructed to analyze genetic evolution relationships.The complete geno-type of the BLL strain was G6-P[1]-I2-R2-C2-M2-A3-N2-T6-E2-H3.Phylogenetic analysis of the VP7 and VP4 genes of the BLL strain showed that the VP7 gene had the highest homology with RVA/Cow-wt/HB01/China/2021,and the VP4 gene of the BLL strain was in the same branch as RVA/Human-tc/ISR/Ro8059/1995.From the sequence alignment of VP8*amino acids,the sialic acid domain of the BLL strain was found to be similar to that in other P[1]strains,but different from those in other types of strains,except for residue 189,which was the same as that in Ro8059 but different from that in other strains.The results suggested that the BLL strain might potentially infect humans.Therefore,continued monitoring and study of the biological characteristics of this strain are necessary to provide more information and evidence supporting further research on the cross-species transmission of group A rotavirus in China.

OBJECTIVE: To identify prognostic genes associated with lysosome-dependent cell death (LDCD) in patients with gastric cancer (GC). METHODS: Differentially expressed genes (DEGs) were identified using The Cancer Genome Atlas - Stomach Adenocarcinoma. Weighted gene co-expression network analysis was performed to identify the key module genes associated with LDCD score. Candidate genes were identified by DEGs and key module genes. Univariate Cox regression analysis, and least absolute shrinkage and selection operator regression and multivariate Cox regression analyses were performed for the selection of prognostic genes, and risk module was established. Subsequently, key cells were identified in the single-cell dataset (GSE183904), and prognostic gene expression was analyzed. Cell proliferation and migration were assessed using the Cell Counting Kit-8 assay and the wound healing assay. RESULTS: A total of 4,465 DEGs, 95 candidate genes, and 4 prognostic genes, including C19orf59, BATF2, TNFAIP2, and TNFSF18, were identified in the analysis. Receiver operating characteristic curves indicated the excellent predictive power of the risk model. Three key cell types (B cells, chief cells, and endothelial/pericyte cells) were identified in the GSE183904 dataset. C19orf59 and TNFAIP2 exhibited predominant expression in macrophage species, whereas TNFAIP2 evolved over time in endothelial/pericyte cells and chief cells. Functional experiments confirmed that interfering with C19orf59 inhibited proliferation and migration in GC cells. CONCLUSION C19orf59, BATF2, TNFAIP2, and TNFSF18 are prognostic genes associated with LDCD in GC. Furthermore, the risk model established in this study showed robust predictive power.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective To clarify the biomechanical properties of oblique lumbar interbody fusion(OLIF)combined with lateral plate(LP)fixation under different bone conditions by means of finite element(FE)analysis,so as to provide mechanical basis for clinical practice.Methods The three-dimensional nonlinear L3_5 FE model of the spine was constructed.Different material properties were assigned to each part of the model to establish a model of normal bone(NB),osteopenia(OS)and osteoporosis(OP)of the lumbar spine.OLIF combined with the following three internal fixation models were established.For NB,there were OLIF alone(M0),OLIF+LP fixation(M1),and OLIF+bilateral pedicle screw(BPS)fixation(M2);for OS,there were OLIF alone(N0),OLIF+LP fixation(N1),and OLIF+BPS fixation(N2);for OP,there were OLIF alone(P0),OLIF+LP fixation(P1),and OLIF+BPS fixation(P2).A 500 N load was applied on the upper surface of L3 to represent the weight of the upper body,and a 7.5 N·m moment was used to simulate the vertebral motion under six different conditions:flexion(FL),extension(EX),left bending(LB),right bending(RB),left rotation(LR)and right rotation(RR).The range of motion(ROM)of the fixed segment of NB,OS and OP models was calculated,and the overall stress of the vertebral body,the stress of the cage and the internal fixation device were recorded.Results Compared with the complete model,the stability of each surgical model increased.Compared with M0,ROM of M1 decreased,especially in the LB and RB,which was roughly equivalent to the stability of BPS but weaker than BPS in the control FL and EX direction.The situation in OS and OP model was similar to that in NB.Under the same internal fixation,L4_5 ROM gradually increased with bone deterioration.The overall intervertebral ROM of N1 in the FL direction increased by 16.1％compared with M1,P1 in the FL direction increased by 32.1％compared with M1,and P1 in the FL direction increased by 19.0％compared with N1.With the increase of posterior internal fixation,the overall stress of vertebral body,Cage and internal fixation stress showed a downward trend.Under the same internal fixation,with the loss of bone mass,the overall stress of the model gradually increased.Compared with M0,P0 increased the most in LR,reaching 56.5％.In the NB and OS models,the peak stress of the LP fixation under FL exceeded the minimum yield strength of the material by 22.7％and 33.8％,respectively,and was less than the minimum fatigue strength and yield strength of the material under the rest of the motion.In the OP,the peak stress of the internal fixation exceeded the minimum fatigue strength of the material at FL and EX,and reached 53.3％(＞50％)at FL.Conclusions Under NB and OS,OLIF combined with LP fixation can significantly improve the stability of the surgical segment,especially in LB and RB directions,and the overall stability is weaker than that of BPS fixation.Under OP,FL and EX may increase the risk of internal fixation failure.Combination with BPS fixation should be considered to improve the safety of fixation.

Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China. Telemedicine, which shortens the distance of medical professionals and the gap of disease diagnosis and treatments in various regions through electronic information, can effectively solve the current problem. Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.
