Objective:To investigate the clinical characteristics and survival analysis of myelodysplastic syndromes(MDS)with RUNX1 gene mutation.Methods:Clinical data of 177 newly diagnosed MDS patients admitted to the Department of Hematology,the Second Affiliated Hospital of Air Force Military Medical University from October 1,2015 to October 31,2022 were retrospectively analyzed.Gene mutation detection was performed by second-generation sequencing technology,and clinical characteristics and prognosis of patients with RUNX1 gene mutation were analyzed.Results:A total of 30 cases(16.95％)of RUNX1 gene mutations were detected,including 15 missense mutations(50.0％),9 frameshift deletion mutations(30.0％),4 splice site mutations(13.3％),1 insertion mutation(3.3％),and 1 nonsense mutation(3.3％).Patients with RUNX1 mutations had a median age of 68.5 years at diagnosis(range:62.25-78.50 years old).There were no significantly differences between RUNX1 mutations and wild type patients in age distribution,gender,peripheral blood white blood cell count,hemoglobin level,bone marrow and peripheral blood blasts ratio,IPSS-R cytogenetics,IPSS-R stage,etc.(P＞0.05).However,there were statistically significant differences in platelet count and whether complicated karyotype.Compared with patients without RUNX1 gene mutation,patients with RUNX1 gene mutation had lower platelet count(P=0.018),and were less likely to have complicated karyotype at initial diagnosis(P=0.01).Cox proportional hazards model analysis showed that when other co variates remained unchanged,the higher the platelet count,the better the survival of patients(HR=0.995,95％CI:0.990-0.999,P=0.036);In the IPSS-M prognostic stratification,keeping other covariates unchanged,the risk of progression or death of myelodysplastic syndrome was significantly lower in the medium to high-risk and low-risk groups compared with the high-risk group(HR=0.149,95％CI:0.031-0.721,P=0.018;HR=0.026,95％CI:0.003-0.234,P=0.001).Survival analysis showed that MDS patients with RUNX1 gene mutation had worse overall survival time(P＜0.001).Patients with RUNX1 mutation had worse OS than non-mutation patients in the early WHO group.RUNX1 mutation and IPSS-M risk stratification mean OS and mean LFS were worse in low-risk patients than in non-mutated patients.Conclusion:RUNX1 gene mutation is an adverse prognostic factor in MDS patients,especially in the IPSS-M prognosis stratification group of low-risk,medium-low risk,medium-high risk and WHO classification of early patients.

Objective To describe the current state of research and future research hotspots through a metrological analysis of the literature in the field of forensic anthropological remains identification re-search.Methods The data retrieved and extracted from the Web of Science Core Collection (WoSCC),the core database of the Web of Science information service platform (hereinafter referred to as "WoS"),was used to analyze the trends and topic changes in research on forensic identification of human re-mains from 1991 to 2022.Network visualisation of publication trends,countries (regions),institutions,authors and topics related to the identification of remains in forensic anthropology was analysed using python 3.9.2 and Gephi 0.10.Results A total of 873 papers written in English in the field of forensic anthropological remains identification research were obtained.The journal with the largest number of publications was Forensic Science International (164 articles).The country (region) with the largest number of published papers was China (90 articles).Katholieke Univ Leuven (Netherlands,21 articles) was the institution with the largest number of publications.Topic analysis revealed that the focus of forensic anthropological remains identification research was sex estimation and age estimation,and the most commonly studied remains were teeth.Conclusion The volume of publications in the field of forensic anthropological remains identification research has a distinct phasing.However,the scope of both international and domestic collaborations remains limited.Traditionally,human remains identifica-tion has primarily relied on key areas such as the pelvis,skull,and teeth.Looking ahead,future re-search will likely focus on the more accurate and efficient identification of multiple skeletal remains through the use of machine learning and deep learning techniques.

OBJECTIVE To evaluate the post-marketing safety of Compound porcine cerebroside and ganglioside injection in patients with ischemic stroke. METHODS A drug-induced， prospective， non-controlled clinical study design was conducted. Using the patients with ischemic stroke who received Compound porcine cerebroside and ganglioside injection at least once in 46 secondary class A and above medical institutions across the country from April 2020 to May 2021 as the monitoring objects， and their basic data， medication information and the occurrence of adverse drug reactions were analyzed. RESULTS Among 13 514 patients with ischemic stroke， the incidence of adverse events was 10.01%， and the incidence of adverse reactions related to Compound porcine cerebroside and ganglioside injection was 0.33%. Drug-related adverse drug reactions were mild or moderate， concentrated in the gastrointestinal system （18 cases）， skin and subcutaneous tissue （10 cases）， nervous system （7 cases） and other systems/organs， mainly including constipation， abdominal pain， diarrhea， rash， pruritus， dizziness and other symptoms. Most of the patients （91.03%） recovered or improved after treatment， and 2 patients died. Among the 45 patients with adverse drug reactions， 84.44% were cured or improved after drug withdrawal or symptomatic treatment， and 15.56% had no significant change. The incidence of adverse drug reactions in tertiary hospitals was significantly higher than that in secondary hospitals， and the incidence of adverse drug reactions in patients with allergic history was significantly higher than that in patients without allergic history （P＜0.05）. Irrational drug use was found in 2.76% of patients， and the incidence of adverse drug reactions（2.95%） was significantly higher than that in patients without irrational drug use（0.26%，P＜0.05）. CONCLUSIONS The adverse drug reaction symptoms of ischemic stroke patients treated with Compound porcine cerebroside and ganglioside injection are relatively common， the incidence rate is generally low， and it is related to the patients’ physique and whether the drug use is standardized.

Objective:To study the predictive value of Barcelona clinic liver cancer (BCLC) staging system combined with albumin-indocyanine green (ALICE) score (ALICE-BCLC) in hepatectomy for hepatocellular carcinoma, and compare it with BCLC staging system combined with Child-Pugh score (CP-BCLC).Methods:The clinical data of 311 patients with hepatocellular carcinoma who underwent hepatectomy at Jinhua Hospital Affiliated to Zhejiang University from April 2012 to June 2021 were analyzed retrospectively. There were 271 males and 40 females, with a median age of 59 years old (range 26 to 92 years old). These patients were divided into two groups based on the ALICE-BCLC: the ALICE-BCLC grade 0 group ( n=63) and the ALICE-BCLC grade A group ( n=248); and another two groups based on the CP-BCLC: the CP-BCLC grade 0 group ( n=58) and the CP-BCLC grade A group ( n=253). The clinical data, including indocyanine green retention rate at 15 min, and albumin were collected and the scores were calculated. Follow-up was conducted by combining outpatient visits with telephone calls. The survival rate was calculated by the life method, and survival curves were drawn by the Kaplan-Meier method. The multivariate Cox regression model was used to determine the main factors affecting prognosis. Weighted Kappa was used to compare consistency of the two staging systems. Results:Multivariate analysis showed that a maximum tumor diameter >5 cm, total bilirubin >18 μmol/L, major hepatectomy, CP-BCLC grade A and ALICE-BCLC grade A to be independent risk factors affecting overall survival of patients with hepatocellular carcinoma after liver resection with curative intent (all P<0.05). The median survival of patients in the CP-BCLC grade 0 group and the CP-BCLC grade A group were 43.0 and 28.0 months, respectively. There was a significant difference between the two groups ( P=0.017). The median survival of patients in the ALICE-BCLC grade 0 group and the ALICE-BCLC grade A group were 41.4 and 28.1 months, respectively. There was a significant difference between the two groups ( P=0.035). The weighted Kappa coefficient of ALICE-BCLC and CP-BCLC was 0.949, showing a strong consistency ( P<0.001). Conclusion:ALICE-BCLC showed a good predictive value for prognosis of hepatocellular carcinoma after liver resection, and it had a similar overall prognostic discrimination ability as CP-BCLC.

Authoritative experts in the industry were invited to give comment and guidance to form a report. Centering on clinical research of dominant diseases， thematic research was carried out in the aspects of practice， human experience-based evidence， and transformation path. Through the systematic study of the dominant diseases， the advantages of TCM in different stages of disease treatment were excavated to constantly improve the prevention and treatment ability of TCM and carry forward the advancement of TCM theory and practice. At the same time， the communication and understanding between traditional Chinese and western medicine were improved， laying the foundation for the further formation of industry guidelines or consensus and comprehensive promotion. These seminars are expected to provide references for the development of policy planning， clinical diagnosis and treatment， health economy， and social services in TCM and lay the foundation for the formation of a new modern diagnosis and treatment system with Chinese characteristics.

Objective:To explore the clinical efficacy of Masquelet technique combined with tissue flap transfer in the treatment of infectious composite bone and soft tissue defects in the early and middle stages after internal fixation for tibial fractures.Methods:From October 2017 to November 2020, 12 patients (13 tibial fractures) with infectious bone and soft tissue defects in the early and middle stages after internal fixation were treated in the Department of Orthopaedics, 988th Hospital of the Joint Logistics Support Force of CPLA by two-phased surgery with retaining internal fixation. Phase I procedures were thoroughly removal of the infected lesions and failed screws, preserving internal implants as many as possible, implantation of absorbable calcium sulphate and an antibiotics blended string of beads into the distal and proximal medullary cavity of the fractured bones, filling the bone defect and wrapping the internal implants with antibiotics loaded bone cement. The size of defects was 3.5 cm × 5.0 cm-7.5 cm × 14.5 cm, and the flaps for wound coverage sized 4.0 cm × 5.5 cm-8.0 cm × 15.0 cm. As for the repair of donor site, 8 limbs were sutured directly, 5 limbs could not be closed completely, and the remaining wounds were covered by skin grafting after suture. Based on well control of infection and stable clinical signs, fillings of bone cement were then removed in Phase II surgery, or 6-9 weeks after primary surgery. Autologous cancellous bone pieces or composite allogeneic bone were fully implanted around the induction membrane formed by Masquelet technique, and auxiliary steel plates were implanted for internal fixation of unstable fractures. After discharge, the patients visited the outpatient clinic regularly, and combined with Wechat follow-up. The texture, colour and bone healing were observed. At the last follow-up, the function of the affected limbs were assessed according to Johner-Wruhs evaluation standard.Results:After Phase I surgery, 13 flaps survived smoothly without vascular compromise. The wounds healed in Phase I. Two patients (2 sides) had recurrent infections. Re-debridement was performed and external fixation was applied after removal of internal fixation. After Phase II surgery, all patients were included in 12-26 months of follow-up, with an average of 18 months. Thirteen lower leg fractures healed well, and the time of bone healing was 16-25 (average 19.5) weeks. The Johner Wruhs criteria was used in evaluation of the function of affected limbs, and it was found that 6 patients were in excellent, 5 in good and 2 in fair.Conclusion:It is feasible while preserving the internal implants, to use membrane induction technique (Masquelet technique) combined with flap transfer, together with the absorbable calcium sulphate antibiotic sustained-release beads as a carrier in the phased treatment of infectious bone defects and bone exposure in the early and middle stages after the surgery of tibial internal fixation. It also gives a higher rate of excellence in surgical outcome. This study explores a treatment procedure for traumatic bone infection combined with composite soft tissue defects.

OBJECTIVE: To analyze the intellectual landscape and emerging research trends of Chinese medicine (CM) in the management of pediatric asthma through a scientometric study. METHODS: Publications related to CM in the management of pediatric asthma were retrieved from the Web of Science Core Collection using relevant keywords. A scientometric study was performed using CiteSpace and VOSviewer. RESULTS: A total of 1,673 original articles and reviews from 1991 to 2019 were included in the analysis. The amount of annual publications had a gradual increase with time. USA was the major contributor both in country and institution analyses. Based on the co-citation, the published journals were grouped into 4 clusters. Keyword analysis indicated that the main hotspots were: (1) comprehensive management; (2) risk factors, mechanism, and prevalence; (3) prevention and treatment; (4) inflammation; and (5) environmental research. Lastly, we predicted that three emerging trends were quality of life promotion, immune response, and combination therapy. CONCLUSIONS CM research in the management of pediatric asthma will maintain the current trend of steady growth. This scientometric analysis may help scientists to identify the areas of interests and future directions in the field.

Objective:To investiagte the ability of albumin-indocyanine green (ALICE) score, albumin-bilirubin (ALBI) score and Child-Pugh score in predicting postoperative liver failure (PHLF) in patients with hepatocellular carcinoma, and to determine the clinical value of ALICE score.Methods:The clinical data of 397 patients with hepatocellular carcinoma who underwent hepatectomy in the Department of Hepatobiliary and Pancreatic Surgery, Jinhua Hospital Affiliated to Zhejiang University from June 2015 to June 2021 were retrospectively analyzed, including 350 males and 47 females, aged (58.9±11.2) years. Univariate and multivariate logistic regression were used to analyze the risk factors of PHLF. The predictive ability of ALICE score for PHLF was evaluated by receiver operating characteristic (ROC) curve, and compared with ALBI score and Child-Pugh score.Results:There were 74 patients with PHLF and 323 patients without PHLF. Multivariate logistic regression analysis showed that Child-Pugh score ( OR=1.630, 95% CI: 1.251-2.486, P=0.034), ALBI score ( OR=1.863, 95% CI: 1.028-3.119, P=0.049) and ALICE score ( OR=1.759, 95% CI: 1.216-3.078, P=0.038) were independent risk factors for PHLF in patients with hepatocellular carcinoma, and the risk of PHLF increased with the increase of grade. The area under the ROC curve of ALICE score predicting PHLF in patients with hepatocellular carcinoma was 0.613 (95% CI: 0.564-0.662), the area under the ALBI score was 0.612 (95% CI: 0.563-0.661), and the area under the Child-Pugh score was 0.555 (95% CI: 0.505-0.605). The ALICE score was better than the Child-Pugh score, and the difference was statistically significant ( z=2.04, P=0.041). In small liver resection patients, ALICE score was better than Child-Pugh score ( z=2.61, P=0.009). There was no significant difference betwenn ALICE score and ALBI score ( z=0.06, P=0.954). Conclusion:ALICE score can predict the occurrence of PHLF in patients with hepatocellular carcinoma, especially in patients with small liver resection, its value is similar to ALBI score, but better than Child-Pugh score.

Objective:To investigate the efficacy of the nutrient vessel of medial and lateral sural subcutaneous nerve chimeric tissue flap based on posterior perforating branch of peroneal artery to repair the composite tissue defect in the Achilles tendon area.Methods:From January 2016 to June 2021, 12 patients suffering from infectious wound with defect of Achilles tendon were treated in the Department of Trauma and Microscopic Orthopaedics, 988th Hospital of the Joint Logistics Support Force of PLA. The area of soft tissue defect around Achilles tendon was 2.5 cm× 4.5 cm-8.0 cm×12.5 cm, and the length of the defect of Achilles tendon was 3.0-7.0 cm. The defect around the Achilles tendon were repaired with the nutrient vessel of medial and lateral sural subcutaneous nerve chimeric Achilles tendon flap (ATF) and the posterior perforating branch of peroneal artery was used as the vessel of blood supply. The size of flap was 3.0 cm×5.0 cm-9.0 cm×13.0 cm, and the size of the ATF was 3.0 cm×4.0 cm-3.0 cm×8.0 cm. The donor sites were sutured directly (8 cases) or repaired with skin graft (4 cases). External fixation were put on for 6 weeks after surgery. Then the external fixation was removed and the functional exercise gradually started. Outpatient clinic follow-ups were carried out regularly. Thermann Achilles tendon function assessment system was used to evaluate the last follow-up.Results:The chimeric ATF was harvested and the blood supply of each flap was good during the operation. There was no vascular crisis after surgery. The flaps survived smoothly and the wound achieved grade A healing. All patients were entered follow-up that lasted for 10-24 months. There was good appearance of flaps with minor bloating, and the colour of flaps was similar to the skin around the receiving site. The texture was soft with normal function of the lower legs and ankle. Tendon function was evaluated by Thermann Achilles tendon function assessment system, the result were 8 cases in excellent and 4 cases in good.Conclusion:The nutrient vessel of medial and lateral sural subcutaneous nerve chimeric tissue flap based on posterior perforating branch of peroneal artery can accurately repair a composite tissue defect in the Achilles tendon area, and it is one of the effective methods for the repair of a composite soft tissue wound with Achilles tendon defect.

Objective To analyze the polymorphism of Plasmodium lactate dehydrogenase (pLDH) gene and predict B-cell epitopes in pLDH peptides in four species of human malaria parasites. Methods The blood samples and epidemiological characteristics were collected from malaria cases in Yunnan Province registered in the National Notifiable Disease Report System. The pLDH genes of four human Plasmodium species were amplified using nested PCR assay and sequenced. The polymorphisms of pLDH genes was analyzed using the software MEGA version 7.0.26 and DnaSP version 5.10, and the B-cell epitopes were predicted in pLDH peptides using the Immune Epitope Database (IEDB). Results The sequences of P. vivax LDH (PvLDH), P. falciparum LDH (PfLDH), P. ovale LDH (PoLDH) and P. malariae LDH (PmLDH) genes were obtained from 153, 29, 17 and 11 blood samples from patients with P. vivax, P. falciparum, P. ovale and P. malariae malaria, respectively, which included 15, 2, 4 and 2 haplotypes and had a nucleotide diversity (π) of 0.104. A high level of intra-species differentiation was seen in the PoLDH gene (π = 0.012), and the π values were all < 0.001 for PvLDH, PfLDH and PmLDH genes. Active regions of B-cell antigen were predicted in the pLDH peptide chain of four human malaria parasites, of 4 to 5 in each chain, and the activity score was approximately 0.430. Among these peptide chains, the “86-PGKSDKEWNRD-96” short-peptide was a B-cell epitope shared by all four species of human malaria parasites, and the “266-GQYGHS (T)-271” short-peptide was present in PvLDH and PoLDH peptide chains, while “212-EEVEGIFDR-220” was only found in the PvLDH peptide chain, and “208-LISDAE-213” was only seen in the PfLDH peptide chain. Conclusions The PoLDH gene polymorphism may be derived from the weak negative purification selection, while PvLDH, PfLDH and PmLDH genes may maintain a relatively conservative state. There may be two B-cell epitopes “212-EEVEGIFDR-220” and “208-LISDAE-213” in the proximal region of the C terminal in the pLDH peptide chain, which is feasible to differentiate between P. vivax and P. falciparum infections.
