The treatment of migraine is categorized into acute treatment and preventive treatment,and existing guidelines for the treatment of migraine usually describe the regimens for the two treatment methods separately,while some studies in recent years have found a close relationship between the two treatment methods.With the introduction of calcito-nin gene-related peptide-antagonizing drugs,such treatment methods may transcend the traditional dividing line between the acute and preventive treatment drugs,offering the possibility of an entirely new approach for the treatment of migraine,whereby acute treatment may have prophylactic benefits and prophylactic treatment may have the effect of acute treatment.At the same time,clinicians should understand that acute and preventive treatment methods are not absolutely indepen-dent treatment modes,and they are closely associated with each other,both with the ultimate goal of better migraine man-agement.Clinicians should develop individualized treatment regimens based on the specific condition of the patient,in or-der to improve the efficacy of acute and preventive treatment methods and reduce disease burden.

Atherosclerosis （AS） is a chronic inflammatory pathological process in which lipid and/or fibrous substances are deposited in the intima of arteries， and it is one of the pathological bases of many cardiovascular and cerebrovascular diseases. Endoplasmic reticulum stress （ERS） is a protective mechanism of cell adaptation. Moderate ERS can reduce abnormal protein aggregation and increase the degradation of misfolded proteins to repair and stabilize the internal environment， while excessive ERS can cause unfolded protein reaction， activate inflammation， oxidative stress， apoptosis， autophagy， and other downstream pathways， and lead to cell damage， or even apoptosis. A large number of studies have shown that ERS mediates a variety of pathological processes related to AS， affects endothelial cells， smooth muscle cells， macrophages， endothelial progenitor cells， and other cell components closely related to its occurrence and development， influences the progress of AS by regulating cell function， and promotes the formation of AS plaque， the transformation of stable plaque to unstable plaque， and the rupture of unstable plaque. Regulation of ERS may be a key target for the prevention and treatment of AS， and it is a research hotspot at present. Traditional Chinese medicine （TCM） believes that the origin of AS is the imbalance of Yin and Yang， the disharmony of Zangfu organs， and the abnormal operation of Qi， blood， and body fluid， which leads to the accumulation of phlegm， blood stasis， and other pathological products in the pulse channels， making the blood flow blocked or misfunction and causing the disease， which belongs to the syndrome of deficiency in origin and excess in superficiality. As the pathogenesis of AS is complex， and the symptoms are diverse， TCM has significant advantages in treating AS because of its multiple targets， multiple pathways， stable efficacy， strong individualization， and high safety. This paper systematically elaborated on the role of ERS in the occurrence and development of AS and summarized the mechanism research on the regulation and control of ERS by Chinese herbal monomer， Chinese herbal extract， Chinese herbal compound， and proprietary medicine， so as to provide a theoretical basis for clinical research and drug development in the prevention and treatment of AS.

Objective:To analyze three reconstruction techniques and mid-term clinical outcomes of hip revision for acetabular bone defect after total hip arthroplasty (THA).Methods:This is a retrospective case series study. Included in the study were 109 patients (109 hips) with acetabular bone defect after THA reconstructions in hip revisions from January 2015 to December 2021 in the Senior Department of Orthopaedics, the Forth Medical Center of Chinese People′s Liberation Army General Hospital and the Department of Orthopaedics, the First Medical Center of Chinese People′s Liberation Army General Hospital. According to the preoperative simulated surgeries and different bone defect reconstruction techniques, patients were divided into a normal cup group, an augment group or a triflange group,respectively. There were 54 patients (54 hips) in the normal cup group, reconstructed with the uncemented porous metal cup (including Jumbo cup), with 23 males and 31 females, aged (59.6±9.9) years (range:32 to 76 years); 44 patients (44 hips) in the augment group, reconstructed with the individualized three-dimensional (3D) printed porous metal augment and uncemented porous metal cup, with 18 males and 26 females, aged (52.8±13.6) years(range:17 to 76 years); 11 patients (11 hips) in the triflange group, reconstructed by the individualized 3D printed porous metal triflange cup, with 5 males and 6 females, aged (59.4±11.2) years (range: 43 to 78 years). Radiographic results, including rotation center height, rotation center offset, and leg length discrepancy (LLD) and clinical results, including Harris hip score (HHS) and visual analogue scale(VAS) were evaluated outpatient at 3, 6, 12 months after the operation and annually thereafter. The last follow-up was completed in March 2024, and all parameters at the last follow-up and before the operation were compared. Paired sample t test and repeated measurement ANOVA were used for the radiographic and clinical parameters before and after the operation. Results:All hip revisions for patients with acetabular bone defect after THA were completed and followed for more than two years. The follow-up time of the normal cup group was (6.5±1.7) years (range: 2.8 to 9.3 years), and that of the augment group was (6.0±1.3) years (range: 3.5 to 9.0 years). The follow-up time of the triflange group was (2.8±0.6) years (range: 2.0 to 3.8 years). At the last follow-up, the rotation center height, rotation center offset and LLD of 54 hips in the normal cup group were (24.2±5.6) mm, (29.1±5.5) mm and (4.6±3.3) mm, respectively, and the rotation center height and LLD were significantly lower than those of the preoperative hips ( t=9.671, P<0.01; t=6.073, P<0.01). In the augment group, the rotational center height, the rotation center offset and the LLD of 44 hips were (22.4±9.0) mm, (25.4±5.5) mm and (6.0±4.0) mm, respectively, which were significantly lower than those of the preoperative hips ( t=9.071, P<0.01; t=11.345, P<0.01; t=4.927, P<0.01). In the triflange group, the rotational center height, the rotation center offset and LLD of 11 hips were (22.7±6.0) mm,(30.9±8.0) mm and (5.3±2.2) mm, respectively, and the rotation center height and LLD were significantly lower than those of the preoperative hips ( t=2.716, P=0.022; t=6.226, P<0.01). At the last follow-up, fractures occurred in 3 patients and dislocation occurred in 1 patient in the normal cup group, and fracture reduction and closed reduction were administered under anesthesia, respectively. In the augment group, dislocation occurred in 1 patient and open reduction under anesthesia was performed. The HHS and VAS of the three groups improved significantly after surgery and the differences were statistically significant (all P<0.01). There was no complication in the triflange group. The X-ray at the last follow-up showed that all prostheses and augments were in stable positions and no loosening or migration was observed. Conclusions:For patients with acetabular bone defect after THA undergoing hip revisions, preoperative surgical simulation and rehearsal could help surgeons choose convenient and efficient reconstruction techniques. The targeted selection of Jumbo cup, individualized 3D printed metal augment, and customized triflange cup could achieve satisfactory clinical outcomes.

ObjectiveTo establish an ischemia-reperfusion model in cynomolgus macaques and to analyse the effects of edaravone intervention. MethodsA total of fifteen adult male cynomolgus macaques were randomly divided into three groups: sham operation (Sham group, n=3), ischemia-reperfusion model (Model group, n=6) and edaravone treatment (Edaravone group, n=6). Ischemic-reperfusion model of cynomolgus macaques was established by clamping the M1 branch of the left cerebral artery for 1 h. After 2 h of reperfusion, the animals in Edaravone group were injected with 0.5 mg/kg edaravone intravenously for intervention treatment, while the animals in Sham and Model groups were injected with an equal volume of normal saline intravenously, twice a day, from the 2nd to 7th day. The behavioral video recordings, clinical observations and neurological deficit scores of cynomolgus macaques were obtained, and brain edema volume and cerebral ischemia volume were statistically analyzed. ResultsCompared with the Sham group, the animals in Model group showed typical symptoms of ischemic stroke, with a significant increase in the neurological deficit score， the volumes of edema and infarct of brain tissue (all P＜0.01). Compared with Model group, the neurological deficit score, the volumes of edema and infarct of brain tissue were significantly reduced in Edaravone group (all P＜0.05). ConclusionAn animal model of ischemia-reperfusion in cynomolgus macaques was successfully established, and edaravone was confirmed to alleviate the damage caused by ischemia-reperfusion.

Objective:To investigate the serum antibody level in children with pertussis in Hangzhou city, and to evaluate the incidence of pertussis in children and the immunization effect of vaccine.Methods:A retrospective study was conducted.The pertussis toxin IgG antibody levels in 1 486 children aged 0-14 who received physical exa-mination in Hangzhou Children′s Hospital from January to December 2018 of were collected and analyzed.Serum antibody level ≥30 IU/mL was considered seropositive.The children enrolled were divided into the 0-3-year-old, 4-6-year-old, 7-9-year-old and 10-14-year-old groups; then the children under 3 years old were subdivided into groups of 0-<3 months, 3-<6 months, 6-<9 months, 9-<12 months, 12-<18 months, and 18-≤ 36 months; finally, the children were grouped according to their vaccination times, the pertussis toxin IgG antibody level and the infection rate of pertussis were compared among different groups by Mann- Whitney U, Kruskal- Wallis and χ2 tests. Results:The overall positive rate of the pertussis toxin IgG antibody was 23.62% (351/1 486), and the median antibody concentration was 6.60 IU/mL.Among children aged 0-14, the 0-3-year-old children had the highest positive rate of the pertussis toxin IgG antibody and the highest median antibody concentration, which were 24.58% (29/118) and 6.95 IU/mL, respectively.There was no significant difference in the antibody positive rate and the median antibody concentration among different age groups (all P>0.05). Among different subgroups of children aged 0-3, the pertussis toxin IgG antibody positive rate and the median antibody concentration were statistically significant (all P<0.05). It was predicted that the pertussis infection rate in children over 3 years old in Hangzhou was about 45.99%.The patients receiving more than 3 doses of vaccination accounted for 87.48% (1 300/1 486), and their antibody positive rate was 25.46% (331/1 300). After excluding unvaccinated children, the comparison results suggested that there was statistical significance in the antibody positive rate and median antibody concentration among different vaccination groups ( χ2=24.467, 67.438, all P<0.001). Conclusions:The serum pertussis toxin IgG antibody positive rate in children aged 0-14 in Hangzhou is low, but their predicted pertussis infection rate is higher.Children aged 0-14 are easy to become a main source of infection.Therefore, it is necessary to pay attention to and strengthen the vaccination plan and research, enhance the monitoring of the infection source, and prevent the " recurrence of pertussis" .

Objective:To evaluate the long-term clinical outcomes of total hip arthroplasty with the 4th ceramic-on-ceramic bearing in patients with history of hip injury.Methods:During December 2008 to December 2011, a total of 153 patients (157 hips) with history of hip injury were treated with 4th ceramic-on-ceramic bearing total hip arthroplasty. There were 25 cases (25 hips) were not followed up (16.3%). Ultimately, a total of 128 cases (132 hips) aged 49.26±14.18 (range 17-76) years including 87 males and 41 females were included in the study. In these patients, there were 15 cases (11.4%) with acetabular fracture, 90 cases (68.2%) with femoral fracture, 5 cases (3.8%) with hip dislocation and 22 cases (16.7%) with unknown history. Clinical outcomes, including operation duration, Harris score, range of motion, complications and noises, were evaluated. The survivorship was investigated by using Kaplan-Meier method.Results:The operation duration was 135.61±41.65 (range 64-320) min. The average follow-up duration was 9.62±0.82 (range 8.2-11.3) years. The Harris score increased from preoperative 44.07±19.71 to 94.03±4.10 at the last follow-up ( t=24.155, P<0.001). The range of hip motion increased from 75.90±28.05 degrees to 117.14±12.36 degrees ( t=13.176, P<0.001). There was no significant difference in Harris scores and ranges of motion among the groups with different history of fracture and dislocation. There were periprosthetic fracture in 1 case and hip dislocation in 2 cases. There was no periprosthetic hip infection or fracture of ceramic liner during the follow up. Thirteen cases (13 hips, 9.8%), including squeaking in 9 cases (6.8%) and clicking in 4 cases (3.0%), reported hip noise without pain and impairment on the quality of life. The survivorship was 100% at 10 years when regarded revision as an end point. However, the survivorship was 99.24% (95% CI: 97.8%, 100%) at 10 years when reoperation revision as an end point. Conclusion:Total hip arthroplasty with 4th ceramic-on-ceramic bearing could have excellent results for patients with a history of hip fracture or dislocation in the long-term follow-up. Although the prevalence of hip noise was about 10% in this cohort study, there was no impairment on the quality of life.

Objective: To evaluate the effect of dexmedetomidine on renal fibrosis in a mouse model of renal ischemia-reperfusion (I/R) and the role of serine-threonine kinase (Akt). Methods: Sixty male C57BL/6 mice, aged 8 weeks, weighing 20-25 g, were divided into 5 groups (n=12 each) using a random number table method: sham operation group (S group), renal I/R group (I/R group), renal I/R plus dexmedetomidine group (I/R + D group), renal I/R plus dexmedetomidine plus Akt agonist SC79 group (I/R + D + SC group), and renal I/R plus dexmedetomidine plus normal saline group (I/R+ D+ NS group). Renal I/R injury model was established by clamping the bilateral renal pedicle for 30 min followed by reperfusion.Dexmedetomidine was intraperitoneally injected at 30 min before surgery in I/R+ D, I/R+ D+ SC and I/R+ D+ NS groups.SC79 was intraperitoneally injected as a bolus of 0.04 mg/kg at 1 min of reperfusion, followed by an intraperitoneal injection of the same dose every 24 h until day 7.The serum blood urea nitrogen (BUN) and Scr concentrations were detected at 24 h of reperfusion.Renal tissues were taken, and the damage to the renal tubules was scored.Renal tissues were removed at 14 days of reperfusion to detect the degree of renal fibrosis and expression of collagen 1 (COL1), fibronectin (FN), and α-smooth actin (α-SMA) (by immunofluorescence and Western blot). The expression of phosphorylated Akt (p-Akt) in renal tissues was determined by Western blot at 24 h and 14 day of reperfusion. Results: Compared with group S, the serum BUN and Scr concentrations, renal tubule damage score and degree of renal fibrosis were significantly increased, and the expression of COL1, FN, α-SMA and p-Akt was up-regulated in group I/R (P<0.05). Compared with I/R group, the serum BUN and Scr concentrations, renal tubular damage score and degree of renal fibrosis were significantly decreased, and the expression of COL1, FN, α-SMA and p-Akt was down-regulated in I/R+ D and I/R+ D+ NS groups (P<0.05). Compared with I/R+ D group, the serum BUN and Scr concentrations, renal tubule damage score and degree of renal fibrosis were significantly increased , and the expression of COL1, FN, α-SMA and p-Akt was up-regulated in I/R+ D+ SC group (P<0.05). Conclusion Dexmedetomidine can reduce the degree of renal fibrosis in a mouse model of renal I/R and the mechanism is related to inhibiting activation of Akt.

Objective: To investigate the microbiological test, antibiotic sensitivity and surgical treatment of periprosthetic joint infection(PJI) cases in post total hip arthroplasty (THA) and total knee arthroplasty (TKA) patients. Methods: A retrospective cross-sectional survey was conducted on 318 patients who underwent THA or TKA in 9 clinical centers in Beijing from January 2014 to December 2016.The data of microbiology, antibiotic sensitivity and surgical treatment were collected.The average age of patients was (62.3±13.1) years old (range: 21-86 years old), including 145 males and 173 females.The body mass index was (25.6±3.8) kg/m ² (range: 15.6-38.1 kg/m²). Results: In total, 318 patients had microorganisms detected by periprosthetic tissue culture or synovial fluid culture, 209 cases (65.7%) had Gram-positive bacteria, 29 cases (9.1%) had Gram-negative bacteria, 10 cases (3.1%) had fungi, 3 cases (0.9%) had non-tuberculous mycobacteria, 72 cases (22.6%) were negative, 69 cases (21.7%) had methicillin-resistant bacteria. The antibiotic sensitivity results showed that the overall resistance rate of penicillin, cefuroxime, amoxicillin+clavulanic acid was 79.9%, 69.9%, and 68.1%, respectively; meropenem, vancomycin, and linezolid resistance rate was 0. For the treatment methods of hip and knee PJI, two-stage revision surgery acounted for 72.9% (108/148) and 64.1% (109/170), respectively. One-stage revision surgery accounted for 21.6% (32/148) and 7.6% (13/170), and open debridement surgery accounted for 4.7%(7/148) and 26.4% (45/170). Conclusions Gram-positive bacteria was still the main pathogen of PJI.The methicillin-resistant bacteria and rare bacteria should be payed attention to. The Majority of hip and knee PJI cases were treated by two-stage revision surgery.

Objectives: To analyze the cardiac T2* value, liver iron concentration (LIC) , and related laboratory parameters in myelodysplastic syndrome (MDS) with iron overload and evaluate the changes of organ functions after iron chelation therapy. To explore the value of magnetic resonance imaging (MRI) T2* in making early diagnosis and assessing organs iron overload. Methods: Retrospective investigation was used to observe the cardiac T2* value, LIC, iron metabolism parameters and related laboratory parameters of 85 MDS patients from Nov 2014 to Jan 2018. Among them, 7 MDS patients with Low/Int-1 have received iron chelation therapy for 6 months during two MRI examinations. The above parameters were collected before and after iron chelation therapy for comparison. Results: Correlations were found between heart T2* value and age (rs=-0.290, P=0.007) and left ventricular ejection fraction (LVEF) (rs=0.265, P=0.009) . There was a significant negative correlation between heart T2* value and blood transfusion units (rs=-0.701, P<0.001) . There was a significant positive correlation between LIC and serum ferritin (SF) (rs=0.577, P<0.001) . There was also a correlation between LIC and ALT (rs=0.268, P=0.014) and blood transfusion units (rs=0.244, P=0.034) . There was no correlation between heart T2* and pro-BNP, SF (all P>0.05) , and no correlation between LIC and age (P>0.05) . The increase of heart T2* between the normal and abnormal groups was statistically significant (P=0.005) , but the iron overload ratio of the heart T2*<20 ms was not significant between the two groups. There was statistical significance in the proportion of severe liver iron overload (LIC>15 mg/g DW) (P=0.045) . After iron chelation therapy, the values of SF, transferrin saturation, ALT, AST, pro-BNP and LIC of 7 patients were decreased compared with values before iron chelation therapy, and the peripheral blood cell level was increased. However, the changes of LVEF and T2* values after iron chelation were not obvious. Conclusion MRI T2* may be a predictor of iron overload in patients with MDS in early stage, and may be more valuable compare with LVEF, SF and other laboratory indicators. The safety and repeatability of MRI cardiac T2* examination are recognized, and it can be used as an ideal detection for patients with iron overload.
