Evidence mapping was used to systematically analyze the clinical research evidence of oral Chinese patent medicines in the treatment of intracerebral hemorrhage(ICH), thus revealing the distribution and quality of evidence in this field. The relevant articles were retrieved from CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase, Cochrane Library, and Web of Science from inception to July 5, 2024. The distribution characteristics of evidence were presented numerically and graphically. A total of 35 Chinese patent medicines were identified, involving 261 articles. The basic information of the 35 Chinese patent medicines, publication trend, traditional Chinese medicine(TCM) syndromes, interventions, and outcome indicators were compared and analyzed, and the methodological quality of the articles was evaluated. The results indicated that the clinical scope of Chinese patent medicines in the treatment of ICH was broad. However, the available studies inadequately emphasized the advantages and characteristics of TCM, lacked the safety information and the standards for evaluating outcome indicators, and paid insufficient attention to cognitive ability and neuropsychology. In addition, these articles demonstrated low quality. It is recommended that follow-up clinical research should be standardized and highlight the characteristics of TCM. In the analysis of outcome indicators, TCM syndrome evaluation should be taken as an important outcome indicator, and the evaluation criteria should be unified. Moreover, more attention should be paid to patients' cognitive ability and neuropsychology. The holder of marketing license of Chinese patent medicines should standardize the clinical position and improve the safety information in the medicine instructions according to the relevant requirements of the National Medical Products Administration. Additionally, the proportion of Chinese patent medicines in the category A list of medical insurance should be increased, and the limited medical resources should be rationally allocated.

Objective To observe the cage subsidence after oblique lateral interbody fusion(OLIF)for lumbar spondylo-sis,summarize the characteristics of the cage subsidence,analyze causes,and propose preventive measures.Methods The data of 144 patients of lumbar spine lesions admitted to our hospital from October 2015 to December 2018 were retrospectively ana-lyzed.There were 43 males and 101 females,and the age ranged from 20 to 81 years old,with an average of(60.90±10.06)years old.Disease types:17 patients of lumbar intervertebral disc degenerative disease,12 patients of giant lumbar disc hernia-tion,5 patients of discogenic low back pain,33 patients of lumbar spinal stenosis,26 patients of lumbar degenerative spondy-lolisthesis,28 patients of lumbar spondylolisthesis with spondylolisthesis,11 patients of adjacent vertebral disease after lumbar internal fixation,7 patients of primary spondylitis in the inflammatory outcome stage,and 5 patients of lumbar degenerative scoliosis.Preoperative dual-energy X-ray bone mineral density examination showed 57 patients of osteopenia or osteoporosis,and 87 patients of normal bone density.The number of fusion segments:124 patients of single-segment,11 patients of two-seg-ment,8 patients of three-segment,four-segment 1 patient.There were 40 patients treated by stand-alone OLIF,and 104 patients by OLIF combined with posterior pedicle screw.Observed the occurrence of fusion cage settlement after operation,conducted monofactor analysis on possible risk factors,and observed the influence of fusion cage settlement on clinical results.Results All operations were successfully completed,the median operation time was 99 min,and the median intraoperative blood loss was 106 ml.Intraoperative endplate injury occurred in 30 patients and vertebral fracture occurred in 5 patients.The mean follow-up was(14.57±7.14)months from 6 to 30 months.During the follow-up,except for the patients of primary lumbar interstitial in-flammation and some patients of lumbar spondylolisthesis with spondylolisthesis,the others all had different degrees of cage subsidence.Cage subsidence classification:119 patients were normal subsidence,and 25 patients were abnormal subsidence(23 patients were grade Ⅰ,and 2 patients were grade Ⅱ).There was no loosening or rupture of the pedicle screw system.The height of the intervertebral space recovered from the preoperative average(9.48±1.84)mm to the postoperative average(12.65±2.03)mm,and the average(10.51±1.81)mm at the last follow-up.There were statistical differences between postop-erative and preoperative,and between the last follow-up and postoperative.The interbody fusion rate was 94.4％.The low back pain VAS decreased from the preoperative average(6.55±2.2 9)to the last follow-up(1.40±0.82),and there was statistically significant different.The leg pain VAS decreased from the preoperative average(4.72±1.49)to the final follow-up(0.60± 0.03),and the difference was statistically significant(t=9.13,P＜0.000 1).The ODI index recovered from the preoperative av-erage(38.50±6.98)％to the latest follow-up(11.30±3.27)％,and there was statistically significant different.The complication rate was 31.3％(45/144),and the reoperation rate was 9.72％(14/144).Among them,8 patients were reoperated due to fusion cage subsidence or displacement,accounting for 57.14％(8/14)of reoperation.The fusion cage subsidence in this group had obvious characteristics.The monofactor analysis showed that the number of abnormal subsidence patients in the osteopenia or osteoporosis group,Stand-alone OLIF group,2 or more segments fusion group,and endplate injury group was higher than that in the normal bone mass group,OLIF combined with pedicle screw fixation group,single segment fusion group,and no endplate injury group,and the comparison had statistical differences.Conclusion Cage subsidence is a common phenomenon after 0-LIF surgery.Preoperative osteopenia or osteoporosis,Stand-alone OLIF,2 or more segments of fusion and intraoperative end-plate injury may be important factors for postoperative fusion cage subsidence.Although there is no significant correlation be-tween the degree of cage subsidence and clinical symptoms,there is a risk of cage migration,and prevention needs to be strengthened to reduce serious complications caused by fusion of cage subsidence,including reoperation.

In this study, fluvoxamine maleate sustained-release pellet system tablets were prepared and were used to evaluate their release behaviors in vitro. Fluvoxamine maleate pellets were prepared using centrifugal-spherization method and coated by fluidized bed as bottom-spray. The multi-unit sustained-release pellets and appropriate excipients for prescription volumes were mixed uniformly and then compressed to tablets. Screening and determining the optimal formulation of drug loaded pellets through L8 (2⁴) Taguchi experiment. Using Minitab software to design a DOE experiment with 2⁴ partial factors, including material temperature, fan speed, atomization pressure, and spray rate to optimize the bottom spray coating process. Taking monostearate glycerol ester with a particle size of 24-40 mesh as the main diluent for tableting to relieve the delamination phenomenon between pellets and excipients during tablet pressing and reduce mechanical damage to the coating film. By examining the powder fluidity indexes such as angle of repose, bulk density, tapped density, and Hausner ratio of mixed particles, it was found that the flowability and compressibility are good and suitable for direct compression. Evaluate the basic properties of the sustained-release tablets, investigate the in vitro release behavior and study the release mechanism. The results of in vitro release test showed that the self-made sustained-release tablets could disintegrate into independent pellet units in phosphate buffer at pH 6.8 and release slowly within 24 h, which conformed to the first-order drug release model. The fluvoxamine maleate sustained-release pellet system tablets meet the requirements of preparation design and has a great commercial prospect.

Objective:To establish an in vivo infection model of West Nile virus (WNV) pseudovirus and evaluate the neutralizing activity of antibody WNV-XH1.Methods:A stable cell line that can package the WNV pseudovirus was established in the early stage to prepare the pseudovirus supernatant. The supernatant was concentrated and infected BHK21 cells to detect the titer of the pseudovirus. After intraperitoneal injection of the pseudovirus into C57BL/J mice, bioluminescence imaging was performed to observe the infection status of the pseudovirus in the mice. After simultaneous infection, blood was collected and ELISA was used to detect NS1 levels in mouse serum. The in vivo functional activity of antibody WNV-XH1 was evaluated using the established mouse infection model.Results:Fluorescence was detected in C57BL/J mice infected with WNV pseudovirus, and the NS1 levels in the peripheral blood serum of mice infected with pseudovirus were significantly higher than those of non infected mice (1.453±0.09vs0.305±0.018). After intravenous administration of WNV-XH1 antibody before the attack, the fluorescence signal in the mice decreased and the serum NS1 level decreased (0.384±0.015).Conclusions:A successful in vivo infection model of WNV pseudovirus was established, and it was confirmed that the antibody WNV-XH1 had a protective effect against WNV pseudovirus infection in vivo.

Objective To investigate the protective effect and mechanism of CDK4/6 inhibitor palbociclib against radiation-induced injury in rats'small intestinal crypt epithelial cell line(IEC-6).Methods(1)Using CCK-8 colorimetric assay,colony formation assay,the PI staining method,Annexin V-FITC/PI dual staining and Western blot,the impact of palbociclib on proliferation,cell cycle dynamics,apoptosis,DNA damage,as well as phosphorylation events at Rb-780 and 795 sites in irradiated IEC-6 cells was investigated.(2)An IEC-6 cell line overexpressing Rb was established,and the effects of Rb overexpression on proliferation,cell cycle,and apoptosis in the IEC-6 cell line were assessed using the CCK-8 colorimetric assay,PI staining method,Annexin V-PE/7-AAD dual staining and Western blot.Additionally,the impact of Rb overexpression on the protective effect of palbociclib against radiation damage was verified in the Rb-overexpressing IEC-6 cell line.Results(1)Administration of palbociclib was demonstrated to enhance the proliferative capacity of IEC-6 cells following exposure to 10 Gy X-ray irradiation,increase colony formation ability post 4-8 Gy X-ray exposure while concomitantly reducing the proportion of cells in the G2/M phase after 10 Gy irradiation and diminishing apoptosis in irradiated IEC-6 cells.Protein expression analysis revealed that palbociclib inhibited phosphorylation at Rb-780 and 795 sites and attenuated the production of γ-H2AX in IEC-6 cells following irradiation.(2)After transfection of IEC-6 cells with Rb overexpression lentivirus,there was a significant increase in the total protein expression of Rb.The phosphorylation levels at Rb-780 and 795 sites were markedly elevated.Consequently,cell proliferation was accelerated,the proportion of cells in the S phase of the cell cycle increased,and the apoptotic rate significantly rose after exposure to 10 Gy X-ray irradiation.(3)Treatment with a lower dose of palbociclib(0.05 μmol/L)was found to suppress the phosphorylation of Rb at 780 and 795 sites in IEC-6 cells overexpressing Rb.Additionally,it reduced apoptosis in IEC-6 cells overexpressing Rb following exposure to 10 Gy X-ray irradiation.However,this treatment did not inhibit the phosphorylation of Rb at 780 and 795 sites in IEC-6 cells transfected with the empty vector,nor did it exert a protective effect against radiation-induced damage in these cells.Conclusion The CDK4/6 inhibitor palbociclib demonstrates significant protective effects against radiation-induced damage in rats'intestinal crypt epithelial cell line(IEC-6),with the Rb protein potentially playing a crucial role in mediating this radioprotective response.

Objective:To understand the etiology,clinical characteristics and prognosis of secondary hemophagocytic syndrome(HLH),so as to improve the understanding of HLH and reduce the rates of misdiagnosis and missed diagnosis of HLH.Methods:A retrospective study was conducted to analyze the cause,clinical characteristics,laboratory findings,therapy and outcomes of 75 adult patients with secondary HLH admitted to our hospital from January 2015 to December 2021.Follow-up continued until the last discharge time.Results:Among 75 patients,infection-related HLH was the most common(45.33％),followed by lymphoma-related HLH(17.33％).Fever was the most common clinical manifestation(97.67％).Laboratory indicators such as NK cell activity(98.31％low or absent),sCD25(93.22％increased),and serum ferritin(94.44％elevated)had higher sensitivity in diagnosis.By comparing the clinical manifestations and laboratory indicators of HLH patients with different causes,sex,lymph node enlargement and bone marrow morphology were more valuable for the diagnosis of primary disease(all P＜0.05).By comparing the treatment and clinical outcomes of HLH patients with different causes,the highest clinical remission rate(83.3％)was achieved in patients with autoimmune disease-related HLH treated with hormone+cyclosporine(P＜0.05).The overall 12-month survival rate of all patients was 26.7％,in which the infection-related HLH was the lowest(14.7％)while autoimmune disease-related HLH was the highest(63.6％).Conclusion:The causes and clinical characteristics of adult secondary HLH are varied,with poor prognosis and heterogeneity in disease severity.It is important to identify HLH cause early for diagnosis and needed to further understand HLH.

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.
