The Compilation Instructions for Expert Consensus on Clinical Application of Dieda Huoxue capsules systematically expound the development methods and evidence-based basis of this consensus. In view of the weak clinical application evidence and ambiguous indications of Dieda Huoxue capsules， the Institute of Basic Research in Clinical Medicine of the China Academy of Chinese Medical Sciences and Wangjing Hospital took the lead and collaborated with 33 experts from 28 medical institutions nationwide. They strictly followed the World Health Organization （WHO） guideline-making norms and the Grading of Recommendations Assessment， Development and Evaluations （GRADE） evidence-grading system and completed the compilation through multidisciplinary cooperation. The workflow included constructing clinical questions （19 items were screened by the nominal group technique）， retrieving evidence （from Chinese and English databases and grey literature）， assessing safety （integrating drug monitoring data and clinical investigations）， and forming recommendations and consensus suggestions （3 recommendations were reached via the GRADE grid method， and 16 consensus suggestions were reached by the majority vote rule）. The results indicate that the consensus clearly states that this medicine （Dieda Huoxue capsules） is applicable to conditions like traumatic injury， blood stasis-induced pain， and sudden lumbar sprains. The recommended dose is 6 capsules each time， twice a day. Combining oral administration with external application can enhance the efficacy， and elderly patients should take the medicine at intervals. Safety monitoring suggests that it should be used with caution in people with a bleeding tendency and those with an allergic constitution. The compilation process involved three rounds of reviews by internal and external experts. Literature analysis， the Delphi method， and clinical applicability tests were employed to ensure methodological rigor. The compilation instructions comprehensively present key aspects such as project approval and registration， conflict-of-interest statements， and evidence evaluation through 12 appendices， providing methodological support for the clinical translation of the consensus. In the future， it will be continuously improved through a dynamic revision mechanism.

Objective:To explore the potential of integrating virtual surgery with three-dimensional (3D) printed guides in the surgical management of mandibular benign tumors and subsequent reconstruction of bone defects.Methods:A retrospective analysis was conducted on the clinical data of patients who underwent computer-assisted resection and vascularized fibular flap reconstruction for benign mandibular tumors at the Department of Oral and Maxillofacial Surgery, First Affiliated Hospital of Zhengzhou University, from June 2013 to December 2020. According to the utilization of guide plates for mandibular and fibular osteotomy during surgical procedures or not, the patients were categorized into two cohorts: a guide plate cohort and a non-guide plate cohort. In the guide plate group, custom-designed gudie plates based on virtual surgical plans were fabricated using 3D printing technology and employed intraoperatively; In the non-guide plate group, surgery was exclusively performed based on virtual surgical plan and prebent titanium plate without any supplementary plating. The measured outcomes included fibular flap osteotomy, operation duration, and clinical flap survival. Computed tomography images obtained one week post-surgery were utilized to assess the intersegmental commissure degree between fibular segments as well as between fibular segments and mandible, commissure degree between fibular segments and prebent titanium plate, and condyle position. The satisfaction of patients with their facial appearance was evaluated 6 months after the surgery using a visual analogue scale. Statistical analysis was conducted using SPSS 21.0 software. Independent sample t-tests was utilized to compare the duration of operation and and postoperative evaluation of facial appearance, the Chi-square tests was utilized for condyle position, commissure degrees among interactions involving fibular segments, prebent titanium plates, bone segments( P<0.05 denoted statistical significance). Results:A total of 30 patients were enrolled, comprising 17 males and 13 females, with a median age of 24 years (16-64 years). The preparation process of fibular flaps proceeded smoothly. The required length of fibula was measured as (14.1 ± 1.9) cm (5.7-18.1 cm), while the number of fibular segments ranged from 2 to 4, averaging at approximately 2.9 ± 0.6. The mandibular defects were repaired using a single-layer fibula in 12 cases, a vascularized folded fibula in 7 cases and a combination of vascularized and non-vascularized fibula in 11 cases. The operation time for the guide plate group was recorded as ( 335.9 ± 64.0) min (240-433 min), while it was observed to be (470.7 ± 140.5 ) min (280-680 min) for the non-guide plate group.The postoperative follow-up duration ranged from 9 to 23 months, with an average period of 11 months. All fibular flaps demonstrated clinical survival. The number of patients with good commissure degree between fibular and mandibular segments, between prebent titanium plate and fibular and mandibular segments and the position of condyle were 15, 15 and 13 cases in guide plate group, 10, 13 and 11 cases in non-guide plate group respectively. The statistical analysis revealed a significant difference ( P<0.05) in the degree of commissure between the fibular and the mandibular segments (15/15 vs. 10/15) in the two groups. Both groups exhibited high levels of satisfaction regarding their postoperative facial appearance at the 6 months follow-up, observed to be 9.6±0.5 and 9.3±0.5 respectively, and the statisticla analysis revealed non-significant difference ( P>0.05). Conclusion:The integration of virtual surgery with 3D printed guide plates can effectively reduce operative time and improve precision in the repair and reconstruction of free-fibular flaps following resection of benign tumors of the mandible.

Objective:To investigate the therapeutic effect of digital technology assisted design of fibula flap for the repair of maxillary tumor defect and implant denture.Methods:A retrospective analysis was performed in patients with benign maxillary tumors who were admitted to Department of Oral and Maxillofacial Surgery, the First Affiliated Hospital of Zhengzhou Universityfrom March 2018 to October 2020. Before the surgery, the virtual tumor resection, fibula reconstruction and stereomodels were printed for the fabrication of fibular osteotomy guide plates.And titanium plates were prefabricated with the stereomodels. Personalized titanium meshes were prebent manually. During the operation, the tumor was removed according to the osteotomy guide plate.The fibula was reshaped according to the surgical plan and the guide plate.And maxillary defects were reconstructed using the fibular flap combined with a prebent personalized titanium mesh.Straumann implants were implanted 6-9 months after bone grafting.The upper porcelain crown was repaired 3-4 months after implantation to restore the occlusal relationship and masticatory function. The facial appearance, masticatory function and peri-implant inflammation were followed up.Results:A total of 12 cases were included in this study, 7 males and 5 females, aged 20-55 years, with a median age 36 years old. Among them, there were 3 cases of ossifying fibroma, 7 cases of ameloblastoma, and 2 cases of odontogenic myxoma.According to the James Brown classification, there were 4 cases of Type Ⅱb, 3 cases of Type Ⅱc, 3 cases of Type Ⅱd, and 2 cases of Type Ⅲb. Tumor resection and fibula reconstruction went smoothly in 12 patients and all the free fibular flaps survived 14 days after surgery. The patients had maxillofacial symmetry, good occlusal relationship after the implant repair, and normal chewing and masticatory functions, after 12-48 months of follow-up, with an average of 26 months. The mouth opening reached 2.8-3.3 cm, without obvious peri-implantitis.Conclusion:The use of digital technology to design fibula flap to repair the defect after maxillary tumor resection and implant denture can not only restore the patients’ facial contour, but also restore their occlusal relationship and masticatory function.

Objective:To evaluate the value of preoperative vascular ultrasound parameters in predicting the postoperative lower extremity deep venous thrombosis (DVT) in patients with gynecological malignant tumors.Methods:Ninety-nine patients with gynecological malignant tumors, aged>18 yr, with body mass index<30 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, scheduled for elective surgery under general anesthesia, were selected. Vascular ultrasound examination was performed before surgery. The flow velocity and diameter of common femoral vein (CFV), deep femoral vein (DFV), popliteal vein (POV), and intermuscular vein (IMV) were recorded. Ultrasound examination of lower limb veins (including anterior tibial vein, posterior tibial vein, IMV, CFV, DFV, POV) were conducted at 1-8 days after surgery to determine whether a DVT occurred. The receiver operating charcateristic curve was used to evaluate the accuracy of each indicator in predicting the lower extremity DVT, and the cut-off value was determined based on the maximum principle of Jorden index. Results:The incidence of lower extremity DVT was 13.1%. The area under the curve (95% confidence interval) of the preoperative CFV flow velocity and diameter, DFV flow velocity and diameter, POV flow velocity and diameter, IMV flow velocity and diameter in predicting the lower extremity DVT were 0.769 (0.616-0.923) and 0.800 (0.644-0.950), 0.797 (0.641-0.954) and 0.771 (0.596-0.945), 0.806 (0.645-0.968) and 0.754 (0.606-0.903), 0.764 (0.615-0.914) and 0.818 (0.645-0.990), respectively ( P<0.05), and the predicted cut-off values were 27.13 cm/s and 11.93 mm, 19.31 cm/s and 10.15 mm, 16.04 cm/s and 8.79 mm, 14.39 cm/s and 8.68 mm, respectively, and the sensitivity and specificity were 90.0%, 71.4% and 90.0%, 74.3%; 90.0%, 74.3% and 90.0%, 68.6%; 90.0%, 82.9% and 90.0%, 72.9%; 90.0%, 70.0% and 80.0%, 87.1%, respectively. Conclusions:Preoperative vascular vascular ultrasound parameters can accurately predict the occurrence of postoperative lower extremity DVT in patients with gynecological malignant tumors.

Objective To monitor the antifungal resistance of clinical isolates of Candida spp.in the East China region.Methods MALDI-TOF MS or molecular methods were used to re-identify the strains collected from January 2018 to December 2022.Antifungal susceptibility testing was performed using the broth microdilution method.The susceptibility test results were interpreted according to the breakpoints of 2022 Clinical and Laboratory Standards Institute(CLSI)documents M27 M44s-Ed3 and M57s-Ed4.Results A total of 3 026 strains of Candida were collected,65.33％of which were isolated from sterile body sites,mainly from blood(38.86％)and pleural effusion/ascites(10.21％).The predominant species of Candida were Candida albicans(44.51％),followed by Candida parapsilosis complex(19.46％),Candida tropicalis(13.98％),Candida glabrata(10.34％),and other Candida species(0.79％).Candida albicans showed overall high susceptibility rates to the 10 antifungal drugs tested(the lowest rate being 93.62％).Only 2.97％of the strains showed dose-dependent susceptibility(SDD)to fluconazole.Candida parapsilosis complex had a SDD rate of 2.61％and a resistance rate of 9.42％to fluconazole,and susceptibility rates above 90％to other drugs.Candida glabrata had a SDD rate of 92.01％and a resistance rate of 7.99％to fluconazole,resistance rates of 32.27％and 48.24％to posaconazole and voriconazole non-wild-type strains(NWT),respectively,and susceptibility rates above 90％to other drugs.Candida tropicalis had resistance rates of 29.55％and 26.24％to fluconazole and voriconazole,respectively,resistance rates of 76.60％and 21.99％to posaconazole and echinocandins non-wild-type strains(NWT),and a resistance rate of 2.36％to echinocandins.Conclusions The prevalence and species distribution of Candida spp.in the East China region are consistent with previous domestic and international reports.Candida glabrata exhibits certain degree of resistance to fluconazole,while Candida tropicalis demonstrates higher resistance to triazole drugs.Additionally,echinocandins resistance has emerged in Candida albicans,Candida glabrata,Candida tropicalis,and Candida parapsilosis.

Objective To investigate the effect of linear echoendoscope guided precise endoscopic sphincterotomy(EST)on positive rates of bile amylase(BA)and bile bacteria as well as occult pancreaticobiliary reflux(OPBR)in patients with calculus of common bile duct after endoscopic retrograde cholangiopancreatography(ERCP).Methods The subjects of this study,146 patients with calculus of common bile duct who underwent EST for ERCP from June 2021 to February 2023,were divided into two groups based on EST type,each with 73 cases.Observation group was administrated with linear echoendoscope guided precise EST,control group was administrated traditional EST.The operation conditions of both groups were observed.Liver function indexes[total bilirubin(TBiL),conjugated bilirubin(CB)and alanine aminotransferase(ALT)],inflammatory and stress indicators[C-reactive protein(CRP),high mobility group box-1 protein(HMGB1),cortisol(Cor),norepinephrine(NE)],and the positive rates of BA and bile bacteria were compared between the two groups before operation and 1,3 days after operation.The postoperative complications and recurrence rate 12 months after operation were recorded.Results There was no significant difference in the success rate of lithotomy and operation time between the two groups(P>0.05).The intraoperative blood loss in the observation group was less than that in the control group,and the hospital stay was shorter than that in the control group,and the differences were statistically significant(P<0.05).1 and 3 days after surgery,TBiL,CB and ALT in two groups were lower than those before surgery,the differences were statistically significant(P<0.05),but there was no statistically significant difference between groups(P>0.05).1 and 3 days after surgery,serum CRP,HMGB1,Cor and NE levels and BA concentration in two groups were higher than those before surgery,and observation group was lower than control group,with statistical significance(P<0.05).The positive rate of biliary bacteria 1 and 3 days after surgery in the control group was higher than that before surgery,the difference was statistically significant(P<0.05);the positive rate of biliary bacteria in the observation group was not significantly different at different time points before and after surgery(P>0.05);the positive rate of biliary bacteria in the observation group was lower than that in the control group 1 and 3 days after surgery(P<0.05).The incidence of OPBR and postoperative recurrence rate at 12 months in the observation group(15.07%and 1.37%)were lower than those in the control group(57.53%and 10.96%),and the differences were statistically significant(P<0.05).Conclusion Linear echoendoscope guided precise EST is more effective in mitigating duodenal papillary sphincter injury,preventing duodenal-biliary reflux,inhibiting BA secretion and bacterial proliferation,and reducing the risk of OPBR than traditional EST.
