Cervical spine health issues not only seriously affect patients' quality of life but also impose a heavy burden on the social healthcare system. Existing guidelines lack sufficient clinical guidance on lifestyle and work habits, such as exercise, posture, daily routine, and diet, making it difficult to meet practical needs. To address this, relying on the China Association of Chinese Medicine, Wangjing Hospital of China Academy of Chinese Medical Sciences took the lead and joined hands with more than ten institutions to form a multidisciplinary guideline development group. For the first time, the group developed the Guidelines for Cervical Spine Health Intervention based on evidence-based medicine methods, strictly following the standardized procedures outlined in the World Health Organization Handbook for Guideline Development and the Guiding Principles for the Formulation/Revision of Clinical Practice Guidelines in China (2022 Edition). This proposal systematically explains the methods and steps for developing the guideline, aiming to make the guideline development process scientific, standardized, and transparent.

Immunotherapy has emerged as a revolutionary approach to treat immune-related diseases. Dendritic cells (DCs) play a pivotal role in orchestrating immune responses, making them an attractive target for immunotherapeutic interventions. Modulation of gene expression in DCs using genome editing techniques, such as the CRISPR-Cas system, is important for regulating DC functions. However, the precise delivery of CRISPR-based therapies to DCs has posed a significant challenge. While lipid nanoparticles (LNPs) have been extensively studied for gene editing in tumor cells, their potential application in DCs has remained relatively unexplored. This study investigates the important role of cholesterol in regulating the efficiency of BAMEA-O16B lipid-assisted nanoparticles (BLANs) as carriers of CRISPR/Cas9 for gene editing in DCs. Remarkably, BLANs with low cholesterol density exhibit exceptional mRNA uptake, improved endosomal escape, and efficient single-guide RNA release capabilities. Administration of BLAN_mCas9/gPD-L1 results in substantial PD-L1 gene knockout in conventional dendritic cells (cDCs), accompanied by heightened cDC1 activation, T cell stimulation, and significant suppression of tumor growth. The study underscores the pivotal role of cholesterol density within LNPs, revealing potent influence on gene editing efficacy within DCs. This strategy holds immense promise for the field of cancer immunotherapy, offering a novel avenue for treating immune-related diseases.

Cerebral ischemia-reperfusion injury(CIRI) is a complex cascade process and seriously hinders the recovery of patients with acute ischemic stroke, which has become an urgent public health issue to be addressed. Silent information regulators(SIRTs) are a family of nicotinamide adenine dinucleotide(NAD~+)-dependent deacetylases, capable of deacylating the histone and non-histone lysine groups. Accumulating evidence has demonstrated that SIRTs are able to regulate the pathological processes such as oxidative stress, inflammatory response, mitochondrial dysfunction, and programmed cell death of CIRI through post-translational deacetylation, and exert the neuroprotection function. In this study, we reviewed the papers about the role and regulatory mechanisms of SIRTs in the pathological process of CIRI published in the past decade. Further, we summarized the research advance in the prevention and treatment of CIRI with Chinese medicine targeting SIRTs and the related signaling pathways. This review will provide new targets and theoretical support for the clinical application of Chinese medicine in treating CIRI during the occurrence of ischemic stroke.

ObjectiveTo study the effect and mechanism of Wuwei Xiaoduyin in treating rat renal mesangial cells （HBZY-1） induced by lipopolysaccharide （LPS） through the nuclear factor-κB （NF-κB） signaling pathway. MethodRat HBZY-1 cells were randomly assigned into the normal group， model group， benazepril （50 μmol·L^-1） group， and high- and low-dose （2.75 and 0.69 g·kg^-1） Wuwei Xiaoduyin groups. The normal group， model group， and benazepril group were treated with 10% normal rat serum， and the Wuwei Xiaoduyin groups with 10% medicated serum. Except the normal group， the other four groups were treated with LPS （100 ng·mL^-1） for modeling in vitro. The changes of cell morphology were observed under optical microscope. The expression of NF-κB p65 was detected by immunofluorescence （IF） method. Methyl thiazolyl tetrazolium （MTT） colorimetry was employed to detect cytotoxicity and cell proliferation. The levels of interleukin-1β （IL-1β）， intercellular adhesion molecule-1 （ICAM-1）， laminin （LN）， and fibronectin （FN） in cell supernatant were determined by enzyme-linked immunosorbent assay （ELISA）. The mRNA levels of IL-1β， FN， and NF-κB p65 were measured by real-time fluorescence quantitative PCR. The protein levels of phosphorylated inhibitor of NF-κB kinase β （p-IKKβ）， phosphorylated NF-κB inhibitor （p-IκBα）， and NF-κB p65 were determined by Western blot. ResultCompared with the normal group， the modeling increased cell proliferation （P<0.01）， elevated the levels of IL-1β， ICAM-1， LN， and FN in cell supernatant （P<0.01）， and up-regulated the mRNA levels of IL-1β， FN， and NF-κB p65 （P<0.01） and the protein levels of p-IKKβ， p-IκBα， and NF-κB p65 （P<0.01）. Such changes were recovered by benazepril and Wuwei Xiaoduyin （P<0.05， P<0.01）. ConclusionWuwei Xiaoduyin can mitigate the inflammatory injury of renal mesangial cells induced by LPS by inhibiting the NF-κB signaling pathway.

OBJECTIVE: To evaluate the efficacy of plasma exchange therapy on crescentic IgA nephropathy (IgAN). METHODS: A retrospective analysis was performed in a cohort of patients with crescentic IgAN from January 2012 to September 2020 at 9 sites across China. Clinical and pathological data, as well as therapeutic regimens, were collected. In order to minimize the effect of potential confounders in baseline characteristics, propensity score matching using a 1 ∶1 ratio nearest neighbor algorithm was performed between the adjunctive plasma exchange therapy group and the intensive immunosuppressive therapy group. The primary outcome was end-stage of kidney disease (ESKD). Kaplan-Meier method was used to compare the difference in renal survival between the two groups. RESULTS: A total of 95 crescentic IgAN patients with acute kidney disease were included in this study, including 37 (38.9%) patients receiving adjunctive plasma exchange therapy, and 58 (61.1%) patients receiving intensive immunosuppressive therapy. In the whole cohort, the baseline eGFR was 12.77 (7.28, 21.29) mL/(min·1.73 m²), 24-hour urinary protein quantification was 5.9 (4.0, 8.9) g, and crescent percentage was 64.71% (54.55%, 73.68%). In the study, 23 patients in each group were matched after propensity score matching The median follow-up time was 7 (1, 26) months. As a whole, 29 patients (63.0%) reached ESKD, including 16 patients (69.6%) in the adjunctive plasma exchange therapy group and 13 (56.5%) patients in the intensive immunosuppressive therapy group.. There were no stastical difference between the two groups in terms of baseline eGFR [14.30 (9.31, 17.58) mL/(min·1.73 m²) vs. 11.45 (5.59, 20.79) mL/(min·1.73 m²)], 24-hour urinary protein (7.4±3.4) g vs. (6.6±3.8) g, crescent percentage 64.49%±13.23% vs. 66.41%±12.65% and the proportion of patients received steroid therapy[23 (100.0%) vs. 21 (91.3%)] (All P>0.05). Kaplan-Meier survival analysis demonstrated that there was no significant difference in renal survival rate between the two groups (Log-rank test, P=0.933). CONCLUSION The adjunctive plasma exchange therapy in addition to conventional intense immunosuppressive therapy did not additionally improve the prognosis of crescentic IgA nephropathy.

Nonalcoholic fatty liver disease (NAFLD) is regarded as the most common liver disease with no approved therapeutic drug currently. Silymarin, an extract from the seeds of Silybum marianum, has been used for centuries for the treatment of various liver diseases. Although the hepatoprotective effect of silybin against NAFLD is widely accepted, the underlying mechanism and therapeutic target remain unclear. In this study, NAFLD mice caused by methionine-choline deficient (MCD) diet were orally administrated with silybin to explore the possible mechanism and target. To clarify the contribution of peroxisome proliferator-activated receptor α (PPARα), PPARα antagonist GW6471 was co-administrated with silybin to NAFLD mice. Since silybin was proven as a PPARα partial agonist, the combined effect of silybin with PPARα agonist, fenofibrate, was then evaluated in NAFLD mice. Serum and liver samples were collected to analyze the pharmacological efficacy and expression of PPARα and its targets. As expected, silybin significantly protected mice from MCD-induced NAFLD. Furthermore, silybin reduced lipid accumulation via activating PPARα, inducing the expression of liver cytosolic fatty acid-binding protein, carnitine palmitoyltransferase (Cpt)-1a, Cpt-2, medium chain acyl-CoA dehydrogenase and stearoyl-CoA desaturase-1, and suppressing fatty acid synthase and acetyl-CoA carboxylase α. GW6471 abolished the effect of silybin on PPARα signal and hepatoprotective effect against NAFLD. Moreover, as a partial agonist for PPARα, silybin impaired the powerful lipid-lowering effect of fenofibrate when used together. Taken together, silybin protected mice against NAFLD via activating PPARα to diminish lipid accumulation and it is not suggested to simultaneously take silybin and classical PPARα agonists for NAFLD therapy.

Pancreatic cancer is the most common digestive tract tumor with an increasing incidence in recent years. The poor prognosis of pancreatic cancer is mainly because of the inability of detecting tumor at an early stage,its high potential for early dissemination,and its relatively poor sensitivity to chemotherapy. Most patients have lost the opportunity for surgery when they are diagnosed,which resulted in an urgent need for the development of more effective and safe therapies for pancreatic cancer. However,the current clinical cancer chemotherapy based on gemcitabine leads to poor prognosis in pancreatic patients. With the continuous research on the biological and cellular signaling pathways of pancreatic cancer,there have emerged a great many of novel agents,including new chemotherapeutic,targetable and immune-modulatory drugs,and some drugs have achieved encouraging results. Furthermore,as an alternative and supplementary method,traditional Chinese medicine has shown good application prospects in the field of pancreatic cancer treatment. This article reviews the current status of drug therapy for pancreatic cancer,summarizes the strength and weakness of existing therapeutic drugs in the application process,gives prospects of possible breakthroughs for the pharmacotherapy in the future,and provides certain new ideas and lessons for subsequent drug development.

The combination of morphological characteristics and DNA barcodes was used to a systematic study of Hippocampus spinosissimus,laying the foundation for rapid and accurate identification for the medical seahorse species. According to the reported literature and observation on seahorse samples,the typical characteristics of the H. spinosissimus include highly developed spiny,much short nose,single or double cheeks and strongly developed spines bordering pouch. Genomic DNAs of H. spinosissimus and other related seahorse species were extracted using the TIANamp Marine Animals DNA Kit. The COⅠ and ATP6 genes were amplified and sequenced in both directions. After the verification by Blast,the GC content,intraspecific and interspecific genetic distance,and the Neighbor joining( NJ) phylogenetic trees were analyzed by MEGA 7. The lengths of the COⅠ and ATP6 genes were 649 bp and 602-603 bp,respectively,with the average GC content of 39. 96% and 35. 37%. The maximum intraspecific genetic distances in H. spinosissimus based on COⅠ and ATP were both far less than the minimum interspecific genetic distance between H. spinosissimus and other seahorses,suggesting a significant barcoding gap. NJ analysis results of COⅠ and ATP6 exhibited that all H. spinosissimus species clustered together,indicating that the two DNA barcode could identify H. spinosissimus from other seahorses accurately and quickly. In addition,H. spinosissimus shared a close genetic relationship between H. kelloggi according to the NJ tree. Furthermore,there exits three stable subgroup structure of H. spinosissimus,indicating that COⅠ and ATP6 barcodes could be applied the indicator for the geographical ecology research of H. spinosissimus. The results obtained the typical morphological and molecular identification characteristics of H. spinosissimus,which played central roles for the development of species identification. This study provides an important basis data for expanding the medical seahorse resources and ensuring the safety of clinical medicine.

OBJECTIVETo evaluate the effect and safety of Kuanxiong Aerosol (, KA) on patients with angina pectoris.

METHODSBlock randomization was performed to randomly allocate 750 patients into KA (376 cases) and control groups (374 cases). During an angina attack, the KA group received 3 consecutive sublingual sprays of KA (0.6 mL per spray). The control group received 1 sublingual nitroglycerin tablet (NT, 0.5 mg/tablet). Log-rank tests and Kaplan-Meier estimations were used to estimate the angina remission rates at 6 time-points after treatment (1, 2, 3, 4, 5, and >5 min). Logistic regression analysis was performed to observe the factors inflfluencing the rate of effective angina remission, and the remission rates and incidences of adverse reactions were compared for different Canadian Cardiovascular Society (CCS) classes of angina.

RESULTSThe 5-min remission rates in the KA and control groups were not signifificantly different (94.41% vs. 90.64%, P>0.05). The angina CCS class signifificantly inflfluenced the rate of remission (95% confidence interval = 0.483-0.740, P<0.01). In the CCS subgroup analysis, the 3-and 5-min remission rates for KA and NT were similar in the CCSII and III subgroups (P>0.05), while they were signifificantly better for KA in the CCSI and II subgroups (P<0.05 or P<0.01). Furthermore, the incidence of adverse reactions was signifificantly lower in the KA group than in the control group for the CCSII and III subgroups (9.29% vs. 26.22%, 10.13% vs. 20.88%, P<0.05 or P<0.01).

CONCLUSIONSKA is not inferior to NT in the remission of angina. Furthermore, in CCSII and III patients, KA is superior to NT, with a lower incidence of adverse reactions. (Registration No. ChiCTRIPR-15007204).

Leukemia stem cells (LSC) that were found in chronic myeloid leukemia (CML) responsible for the abnormal proliferation with the potential of self-renewal and multi-directional differentiation are involved in the pathophysiological process for drug resistance and relapse of CML. Autophagy, a conservative lysosomal degradation process that mediates cell degradation and recycling process, plays crucial roles in maintaining the homeostasis and function of intracellular environment. Recent studies suggested that autophagy is involved in the regulation of LSC differentiation and also closely related to the chemo-sensitivity of CML. In this review, we focused on the role of autophagy on chemotherapy sensitivity of CML as well as the leukemia stem cell function for the development of new anti-leukemia drugs.
