Objective To analyze and compare the treatment of HeppleⅤ talus osteochondral injury(OLT)with autologous periosteal iliac bone graft and allogeneic bone powder combined with platelet rich gel(PRP).Methods Totally 62 HeppleⅤOLT patients admitted to our hospital from October 2018 to October 2022 were selected as the research subjects.They were divided into a transplantation group(31 patients received autologous periosteal iliac bone transplantation treatment)and a combination group(31 patients received allogeneic bone powder combined with PRP treatment)based on their treatment methods.Conduct a 12 month postoperative outpatient follow-up study on patients,evaluate and compare the treatment effectiveness,ankle joint range of motion(ROM),American Society of Orthopedic Foot and Ankle Surgeons(AOFAS)ankle posterior foot score,pain score,satisfaction,and incidence of complications between the two groups of patients at 12 months after surgery.Results The total effective rate of the transplantation group(96.77%)was not significantly different from that of the combination group(93.55%,P>0.05).At 12 months after surgery,the ROM and AOFAS scores of both groups improved(P<0.05),and there was no statistically significant difference between the groups(P>0.05).At 1 month,3 months,6 months,and 12 months after surgery,the pain scores of both groups decreased compared to before surgery(P<0.05).The subjective overall satisfaction of patients in the transplantation group(77.42%)was lower than that in the combination group(96.77%,P<0.05).The total incidence of complications in the transplantation group(19.35%)was significantly higher than that in the combination group(3.23%,P<0.05).Conclusion Allogeneic bone powder combined with PRP can avoid additional surgical incisions,increase patient subjective satisfaction,and increase the incidence of postoperative complications.

Objective:To analyze the incidence trend and epidemiological characteristics of typhoid fever in Fujian Province from 2011 to 2022, and understand the high-incidence population and hotspot areas, and provide evidences to develop more targeted prevention and control measures.Methods:The surveillance data of typhoid fever during 2011-2022 in Fujian Province were obtained from the National Disease Reporting Information System and analyzed with SAS 9.4. The spatial autocorrelation analysis of typhoid fever incidence at county/district levels was performed with ArcGlS 10.8.Results:A total of 5 126 cases of typhoid fever were reported in Fujian Province from 2011 to 2022, with an average annual incidence rate of 1.10/100 000. The average annual incidence rate was 0.96/100 000 from 2011 to 2015, 1.49/100 000 from 2016 to 2019, and 0.81/100 000 from 2020 to 2022. The disease occurred all the year round, with high epidemic season from May to September. A total of 23.59% (1 209/5 126) of the cases occurred at the age of 0-4, and 9.62% (493/5 126) at the age of 5-9. The male to female ratio of the cases was 0.97∶1 (2 524∶2 602) for the whole population, 1.19∶1 (925∶777) for people under 10 years old, 0.75∶1 (1 060∶1 404) for people between 10 and 54 years old, and 1.28∶1 (539∶421) for people over 55 years old. Cases in Ningde City accounted for 30.65% (1 571/5 126) of the total cases. Most hotspots were occurred in Ningde City. Recurrent and clustered cases were found in family members.Conclusions:Typhoid fever was prevalent at a low level in Fujian Province during 2011-2022, indicating that strengthening the prevention and control measures should target key areas and populations. The incidence of typhoid fever in Fujian Province showed spatial aggregation phenomenon, and most cases gathered in Ningde City. Intensive study for the influencing factors of spatial clustering should be conducted.

Abstract OBJECTIVE To explore the material basis and mechanism of Crataegi Fructus in improving metabolic hypertension(MH) by using network pharmacology and molecular docking technique.METHODS The components of Crataegi Fructus were collected by HERB, ETCM database and literature survey; screening all ingredients of Crataegi Fructus to improve MH targets through databases such as SwissTargetPrediction and GeneCards; build "active ingredient-target-disease" network of Crataegi Fructus with Cytoscape software; DAVID was used to analyze GO enrichment and KEGG pathway. The core components and core targets were verified by molecular docking with Autodock software. RESULTS The total of 89 active components were screened from Crataegi Fructus and acted on 84 targets. Among them, the core active components of Crataegi Fructus to improve MH were maslinic acid, fomefficinic acid B, linolenic acid, linoleic acid, methyl-n-nonylketone, apigenin, ursolic acid, etc. The core targets were CYP19A1, PPARA, ESR1, PTGS2, PPARG, NR3C1, MMP9, TNF, etc. The mechanism of action mainly involved multiple signaling pathways such as inflammation, glycolipid metabolism, and vascular endothelial function. Molecular docking showed that the core active ingredients of Crataegi Fructus had high affinity with core targets. CONCLUSION Crataegi Fructus may regulate multiple signaling pathways such as TNF, IL-17, AGE-RAGE, HIF-1, cGMP-PKG through multi-component regulation, thereby inhibiting inflammatory response, improving glucose and lipid metabolism abnormalities, and improving vascular endothelial function, so as to comprehensively exert the role of improving MH in various aspects.

Spinocerebellar ataxias are a high clinically and genetically heterogeneous group of neurodegenerative disorders, usually belongs to autosomal dominant hereditary cerebellar ataxia. Spinocerebellar ataxia type 5 (SCA5) is one of the extremely rare subtypes and caused by heterozygous mutation of SPTBN2 gene. A case of infant-onset SCA5 patient is reported, mainly manifested as global developmental delay, ataxia and dysarthria, carrying the heterozygous missense variant c.1438C>T (p. Arg480Trp) in the SPTBN2 gene. This mutation may have an important impact on functional regions of the β-Ⅲ spectrin, leading to the occurrence of disease.

Objective:To explore the surgical strategy of coronary artery bypass grafting(CABG) for moderate ischemic mitral regurgitation(IMR), and to clarify the impact of mitral valve surgical intervention(MVS) on the long-term prognosis of such patients.Methods:The clinical data of 234 consecutive patients with moderate IMR who received CABG from January 2013 to December 2018 were retrospectively included, with 184 males and 50 females. The age ranged from 29 to 78 years, with a mean of(61.5 ± 8.7) years old. According to whether MVS was performed at the same time, they were divided into CABG group(108 cases, CABG alone) and CABG+ MVS group(126 cases, CABG+ MVS at the same time). The long-term cardiac events, all-cause deaths, major cardiovascular and cerebrovascular adverse events(MACCE) and other end events were followed up. A matching queue was established by propensity matching score for statistical analysis.Results:After propensity matching score, a matching queue was established, including 78 pairs of patients. Survival analysis showed that the incidence of long-term cardiac events and postoperative new onset atrial fibrillation in CABG+ MVS group was significantly higher( P<0.05). However, there was no significant difference between the two groups in all-cause mortality, cardiogenic mortality, and the incidence of MACCE events( P>0.05). Cox regression analysis showed that simultaneous CABG+ MVS was a risk factor for long-term cardiac events and new postoperative atrial fibrillation. The results of subgroup studies showed that for patients without tricuspid regurgitation before operation, left ventricular end diastolic diameter>55 mm, and left ventricular ejection fraction(LVEF) ≤0.55, the probability of cardiac events after MVS at the same time of CABG was higher( P<0.05). However, patients with no tricuspid regurgitation before operation, left ventricular end diastolic diameter>55 mm, LVEF≤0.55, and left atrial diameter≥40 mm had a higher probability of atrial fibrillation after MVS at the same time of CABG( P<0.05). Conclusion:CABG can improve left ventricular remodeling in patients with moderate IMR, whether MVS intervention is performed at the same time or not, and the long-term survival rate of both is similar. CABG+ MVS in the same period can maintain a low residual reflux, but the incidence of long-term cardiac events and arrhythmias is high. The longer-term prognosis needs to be further studied. The surgical strategy of such patients should be selected individually according to the specific situation and the surgical quality in medical centers.

After a long-term co-evolution, alphaherpesviruses have established mutual adaptability with their hosts. Some alphaherpesviruses have typical neurotropic characteristics, which have received extensive attention and in-depth research. Neurotropic alphaherpesviruses can break through the host barrier to infect neurons and multiply in large numbers in the neuron cell body to complete further proliferation or establish latent infection in the cell body. Either in the process of infecting neurons or further spreading, alphaherpesviruses will undergo transmission along axons or dendrites, so this process is an integral part of the life cycle of the viruses, and is also a key factor for the viruses to spread in nervous system. Therefore, studies on transportation of alphaherpesviruses in neurons will provide new insights of the viruses and promote the development of corresponding vaccines or targeted therapeutic pharmaceuticals. In addition, the neurotropism of alphaherpesviruses is conducive to the analysis of nerve circuits. Herein, the mechanisms of alphaherpesvirus transport in axons were reviewed, and the research direction and application of the transport of alphaherpesviruses in axons were put forward, which can provide reference for the prevention and control of alphaherpesviral infections.

Objective Big endothelin-1(big ET-1) is associated with the prognosis of various cardiovascular diseases. This study is to explore the predictive value of plasma big ET-1 level for long-term outcome after mitral valvuloplasty in patients with moderate to severe chronic ischemic mitral insufficiency .Methods A total of 142 consecutive patients with moderate to severe chronic ischemic mitral regurgitation who underwent coronary artery bypass grafting and mitral valvuloplasty were enrolled at our center from January 2009 to December 2015.The clinical baseline data were collected and recorded.All patients were followed up.The mortalities and major adverse cardiovascular and cerebrovascular events during the follow-up period were re-corded.Results A total of 142 patients were enrolled, with mean age of(59.4 ±8.3) years.During(51.9 ±22.6) months follow-up, 19 cases(13.4％) died and 35 cases(24.6％) had major adverse cardiovascular and cerebrovascular events.Uni-variate and multivariate Cox regression analysis showed that big ET-1 was an independent risk factor for all-cause mortality (HR=3.970, 95％CI:1.535-10.268) and major adverse cardiovascular and cerebrovascular events(HR=2.754, 95％CI:1.238-6.129).In addition, left ventricular ejection fraction, pulmonary hypertension and stroke history were independent risk factors for all-cause mortality , while left ventricular ejection fraction , stroke history were independent risk factors for major adverse cardiovascular and cerebrovascular events.Conclusion Long-term outcomes of simultaneous coronary artery bypass grafting and mitral valvuloplasty for moderate to severe ischemic mitral insufficiency are satisfactory and big ET-1 is an inde-pendent risk factor for long-term outcomes of these patients.

Objective     To analyze the results of intra-aortic balloon pump (IABP) support in patients receiving coronary artery bypass graft (CABG) and the risk factors of postoperative death. Methods     The clinical data of 334 patients undergoing CABG procedure and receiving IABP support in Fuwai Hospital from January 1999 to April 2012 were retrospectively analyzed. According to the IABP insertion timing, the patients were divided into three groups: pre-, intra- and postoperative IABP groups. There were 45 males and 11 females aged 60.5±10.7 years in the preoperative IABP group, 84 males and 23 females aged 61.1±8.4 years in the intraoperative IABP group and 119 males and 52 females aged 61.4±8.5 years in the postoperative IABP group. Outcomes of the three groups were compared, including mortality, major complications, ICU stay, hospital stay and total costs. Multivariable logistic regression analysis was used to predict independent risk factors for postoperative in-hospital death. Results     The total in-hospital mortality was 16.8% (56/334). Mortality was significantly different among the pre-, intra- and postoperative IABP groups (3.6% vs. 23.4% vs. 17.0%, P=0.006). There was no significant difference in complications among the three groups (P=0.960). Multivariable logistic regression analysis indicated that independent risk factors for postoperative mortality included old age (OR=1.05, P=0.040), female (OR=3.34, P<0.001) and increasing left ventricular end-diastolic diameter (LVEDD, OR=1.06, P=0.040). Preoperative IABP support was protective factor (OR=0.10, P=0.050). Conclusion     The results of IABP support in CABG   patients are satisfactory, and patients with preoperative IABP have a lower mortality. Risk factors for postoperative death include old age, female and increasing LVEDD. Preoperative IABP support is a protective factor.
