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.

Objective To evaluate the characteristics of the mass balance and pharmacokinetics of[14 C]birociclib in Chinese male healthy volunteers after a single oral administration.Methods This study used a 14 C labeled method to investigate the mass balance and biological transformation of birociclib in human.Subjects were given a single oral dose of 360 mg/50 pCi of[14 C]birociclib suspension after meals.The blood,urine,and fecal samples were collected at specified time points/intervals after administration.The radiation levels of 14 C labeled birociclib-related compounds in the blood,plasma,urine,and feces were analyzed using liquid scintillation counting.In addition,a combination of high-performance liquid chromatography and on-line/off-line isotope detectors was used to obtain radioactive isotope metabolite spectra of plasma,urine,and fecal samples,and high-resolution mass spectrometry was used to identify the main metabolites.Results A total of 6 healthy male subjects were enrolled in this study.The median peak time of radioactive components in plasma was 5.00 h and the average terminal elimination half-life was 43.70 h after administration.The radioactive components were basically excreted and cleared from the body within 288.00 hours after administration,and average cumulative recovery rate of radioactive drugs was(94.10±8.19)％.The radioactive drugs were mainly excreted through feces,accounting for(84.60±7.10)％of the dose of radioactive drugs administered.Urine was the secondary excretory pathway,accounting for 9.41％of the dose of radioactive drugs administered.Metabolic analysis indicated that the prototype drug was the main radioactive components in plasma samples.The main metabolites in plasma were RM4(XZP-5286),RM6(XZP-3584),and RM7(XZP-5736).The drugs were mainly cleared from the body in the form of prototype drugs and metabolites.In addition to prototype drugs,a total of 9 metabolites were identified and analyzed in plasma,urine,and fecal samples,all of which were phase 1 metabolites.The main metabolic and clearance pathways of drugs in the body were deethylation,diisopropylat ion,oxidation,etc.Conclusion After a single oral administration of[14C]birociclib suspension to healthy subjects,it was mainly cleared from the body in the form of prototype drugs and metabolites,with feces as the main excretory pathway and urine as the secondary excretory pathway.Drugs mainly undergo metabolic reactions in the body,such as deethylation,diisopropylation,and oxidation.The subjects were well tolerance after administration.

Based on the strategy of metabolomics combined with bioinformatics, this study analyzed the potential allergens and mechanism of pseudo-allergic reactions (PARs) induced by the combined use of Reduning injection and penicillin G injection. All animal experiments and welfare are in accordance with the requirements of the First Affiliated Experimental Animal Ethics and Animal Welfare Committee of Henan University of Chinese Medicine (approval number: YFYDW2020002). Based on UPLC-Q-TOF/MS technology combined with UNIFI software, a total of 21 compounds were identified in Reduning and penicillin G mixed injection. Based on molecular docking technology, 10 potential allergens with strong binding activity to MrgprX2 agonist sites were further screened. Metabolomics analysis using UPLC-Q-TOF/MS technology revealed that 34 differential metabolites such as arachidonic acid, phosphatidylcholine, phosphatidylserine, prostaglandins, and leukotrienes were endogenous differential metabolites of PARs caused by combined use of Reduning injection and penicillin G injection. Through the analysis of the "potential allergen-target-endogenous differential metabolite" interaction network, the chlorogenic acids (such as chlorogenic acid, neochlorogenic acid, cryptochlorogenic acid, and isochlorogenic acid A) and β-lactam allergens in the combination of the two may be mainly regulated by PLD1, PLA2G12A and CYP1A1. The three upstream signal target proteins mainly activate the arachidonic acid metabolic pathway, promote the degranulation of mast cells, release downstream endogenous inflammatory mediators, and induce PARs.

Establish a production line with controllable process and high intelligence, contribute to improve the quality and production efficiency of aconite processed by microwave, and promote the transformation and application of aconite processed by microwave. According to the principle of aconite detoxification and the characteristics of industrial microwave equipment, an industrial production line of aconite processed by microwave was established with diester alkaloids and monoester alkaloids as indicators, and pilot production was carried out. At the same time, the content of active constituents and efficacy were compared with that of the main processed products, such as Shengfupian, Baifupian and Heishunpian. The results showed that the industrial production of aconite processed by microwave can be divided into two stages: "Liquid seal to detoxification - drying and puffing". The content of monoester alkaloids in 10 batches of aconite processed by microwave was 0.071%-0.166% and the content of diester alkaloids was 0.004%-0.016%, which met the relevant requirements of the Chinese Pharmacopoeia in 2020. Compared with Heishunpian and Baifupian, the retention rate of the effective components of aconite processed by microwave was higher. Pharmacological experiments showed that aconite processed by microwave not only retained the anti-inflammatory and analgesic activities of Heishunpian and Baifupian, but also significantly increased the levels of leukocytes and lymphocytes in mice with liver cancer chemotherapy, enhanced the CD4/CD8 ratio in spleen cells of mice (P < 0.05), thus regulating the body's immunity. However, this effect of Baifupian was weak, while Heishunpian and Shengfupian had no such effect. Through the above research, this study established microwave processing line with controllable process and high intelligence, as well produced the aconite processed by microwave with low toxicity and stable quality. It laid a foundation for the industrialized continuous production and clinical positioning of aconite by microwave processed, and provided scientific support for the development and application of microwave technology in the field of traditional Chinese medicine. All animal experiments in this study were reviewed and approved by the Experimental Animal Ethics Committee of Chengdu University of Traditional Chinese Medicine before being carried out (Approval No. 2020-28).

In this study, the crude polysaccharides was extracted from Shengfupian and purified by Sevag deproteinization. Then, the purified neutral polysaccharide fragment was obtained by the DEAE-52 cellulose chromatography column and Sephadex G-100 co-lumn. The structure of polysaccharides was characterized by ultraviolet spectroscopy, infrared spectroscopy, ion chromatography, and gel permeation chromatography. To investigate the anti-inflammatory activity of Shengfupian polysaccharides, LPS was used to induce inflammation in RAW264.7 cells. The expression of the CD86 antibody on surface of M1 cells, the function of macrophages, and the content of NO and IL-6 in the supernatant were examined. An immunodepression model of H22 tumor-bearing mice was established, and the immunomodulatory activity of Shengfupian polysaccharides was evaluated based on the tumor inhibition rate, immune organ index and function, and serum cytokine levels. Research indicated that Shengfupian polysaccharides(80 251 Da) was composed of arabinose, galactose, glucose, and fructose with molar ratio of 0.004∶0.018∶0.913∶0.065. It was smooth and lumpy under the scanning electron microscope. In the concentration range of 25-200 μg·mL~(-1), Shengfupian polysaccharides exhibited little or no toxicity to RAW264.7 cells and could inhibit the polarization of cells to the M1 type and reduce the content of NO and IL-6 in the cell supernatant. It could suppress the phagocytosis of cells at the concentration of 25 μg·mL~(-1), while enhancing the phagocytosis of RAW264.7 cells within the concentration range of 100-200 μg·mL~(-1). The 200 mg·kg~(-1) Shengfupian polysaccharides could alleviate the spleen injury caused by cyclophosphamide, increase the levels of IL-1β and IL-6, and decrease the level of TNF-α in the serum of mice. In conclusion, Shengfupian polysaccharides has anti-inflammatory effect and weak immunomodulatory effect, which may the material basis of Aconm Lateralis Radix Praeparaia for dispelling cold and relieving pain.

OBJECTIVE: To investigate the efficacy and safety of daratumumab in treatment of multiple myeloma (MM) patients with renal impairment (RI). METHODS: The clinical data of 15 MM patients with RI who received daratumumab-based regimen from January 2021 to March 2022 in three centers were retrospectively analyzed. Patients were treated with daratumumab or daratumumab combined with dexamethasone or daratumumab combined with bortezomib and dexamethasone and the curative effect and survival were analyzed. RESULTS: The median age of 15 patients was 64 (ranged 54-82) years old. Six patients were IgG-MM, 2 were IgA-MM,1 was IgD-MM and 6 were light chain MM. Median estinated glomerular filtration rate (eGFR) was 22.48 ml/(min·1.73 M₂). Overall response rate of 11 patients with MM was 91% (≥MR), including 1 case of stringent complete response (sCR), 2 cases of very good partial response (VGPR), 3 cases of partial response (PR) and 4 cases of minor response (MR). The rate of renal response was 60%(9/15), including 4 cases of complete response (CR), 1 case of PR and 4 cases of MR. A median time of optimal renal response was 21 (ranged 7-56) days. With a median follow-up of 3 months, the median progression-free survival and overall survival of all patients were not reached. After treatment with daratumumab-based regimen, grade 1-2 neutropenia was the most common hematological adverse reaction. Non-hematological adverse reactions were mainly infusion-related adverse reactions and infections. CONCLUSION Daratumumab-based regimens have good short-term efficacy and safety in the treatment of multiple myeloma patients with renal impairment.

Objective:To compare the clinical efficacy between bone transport technique combined with bone grafting plus internal fixation and simple bone transport technique in the treatment of large segmental bone defects at lower limbs after trauma.Methods:A retrospective study was conducted to analyze the clinical data of 42 patients with large segmental bone defects at lower limbs after trauma who had been treated at Department of Trauma Orthopaedics, Honghui Hospital Affiliated to Medicine College, Xi'an Jiaotong University from September 2015 to September 2019. The patients were divided into 2 groups according to the different methods of repairing bone defects. In group A of 18 patients subjected to bone transport combined with bone grafting plus internal fixation, there were 11 males and 7 females with an age of (35.2±10.3) years, and 12 tibial defects and 6 femoral defects; in group B of 24 patients subjected to simple bone transport, there were 15 males and 9 females with an age of (37.3±9.4) years, and 17 tibial defects and 7 femoral defects. The external fixation time (EFT), external fixation index (EFI), total cure time and complications were recorded and compared between the 2 groups. At the last follow-up, the Ennecking score for limb functional recovery (score/total score 30) and Self-rating Anxiety Scale (SAS) were used to evaluate respectively the functional recovery of the limbs and postoperative anxiety.Results:The 2 groups were comparable because there was no significant difference between them in preoperative general data or follow-up time ( P>0.05). There was no statistically significant difference in the number of surgeries between the 2 groups ( P>0.05). The EFT [(5.9±1.5) months], EFI [(0.45±0.09) months/cm], total treatment time [(16.2±2.4) months], Ennecking score for limb functional recovery (87.0%±8.6%), SAS score [(43.2±9.0) points], and complications per capita [(0.4±0.2) times/case] in group A were significantly better than those in group B [(15.3±4.2) months, (1.19±0.28) months/cm, (19.7±3.5) months, (77.3%±9.2%), (58.2±9.3) points, and (1.2±0.5) times/case] (all P<0.05). Conclusion:In the treatment of large segmental bone defects at lower limbs, compared with simple bone transport technique, bone transport technique combined with bone grafting plus internal fixation has advantages of shorter external fixation time and overall cure time, a lower rate of complications, and better functional recovery of the limbs.

The electrophysiological activity of the gastrointestinal tract and the mechanical anti-reflux structure of the gastroesophageal junction are the basis of the anti-reflux function of the stomach. Proximal gastrectomy destroys the mechanical structure and normal electrophysiological channels of the anti-reflux. Therefore, the residual gastric function is disordered. Moreover, gastroesophageal reflux is one of the most serious complications. The emergence of various types of anti-reflux surgery through the mechanism of reconstructing mechanical anti-reflux barrier and establishing buffer zone, and the preservation of, the pacing area and vagus nerve of the stomach, the continuity of the jejunal bowel, the original gastroenteric electrophysiological activity of the gastrointestinal tract, and the physiological function of the pyloric sphincter, are all important measures for gastric conservative operations. There are many types of reconstructive approaches after proximal gastrectomy. The design based on the anti-reflux mechanism and the functional reconstruction of mechanical barrier, and the protection of gastrointestinal electrophysiological activities are important considerations for the selected of reconstructive approaches after proximal gastrectomy. In clinical practice, we should consider the principle of individualization and the safety of radical resection of tumor to select a rational reconstructive approaches after proximal gastrectomy.

ObjectiveTo explore the association between daily executive function and core symptoms， the symptoms of attention deficit hyperactivity disorder （ADHD） in children with autism spectrum disorder （ASD）， and the moderating effect of theory of mind and other cognitive abilities on this association. MethodsChildren aged 6-12 years with ASD were recruited， and 86 children were identified according to the inclusion and exclusion criteria. Wechsler Intelligence Test for Children， Fourth Edition （WISC-Ⅳ）， Strange Story Test （SST） and Behavior Rating Inventory of Executive Function （BRIEF） were used to evaluate children's cognitive ability. Swanson Nolan and Pelham-Version Ⅳ Scale （SNAP-Ⅳ）， Social Responsiveness Scale （SRS）， and Repetitive Behavior Scale-Revise （RBS-R） were used to assess the severity of ADHD symptoms， social impairment， and repetitive stereotyped behavior. Multiple linear regression was used to explore the association between daily executive function and ADHD symptoms， social impairment， repetitive stereotyped behaviors. ResultsAfter controlling for the score of strange stories， verbal comprehension index （VCI） and other factors， the full scale score and each index of BRIEF were positively correlated with full scale score of SNAP （b = 0.619-0.741， b’ = 0.637-0.755）， SRS （b = 0.928-1.200， b’ = 0.417-0.513） and RBS-R （b = 0.326-0.525， b’ = 0.339-0.520） in children with ASD （P< 0.05）， and the SNAP total score was more strongly correlated with the full scale BRIEF score and each index score （b’ = 0.637-0.755，P< 0.01）. In addition to daily executive function， strange stories score （b = -2.218- -1.839） and age （b = 3.181-4.037） were also the important factors affecting the social function of children with ASD （P< 0.01）. There were no moderating effects of strange stories score and age on the association between BRIEF score and full scale score of SNAP， SRS， and RBS-R（P> 0.05）. ConclusionThe deficits of daily executive function in school-aged ASD children are significantly associated with core symptoms and ADHD symptoms， and the association is independent of other cognitive domains， such as theory of mind and verbal comprehension intelligence quotient.
