Oropharyngeal squamous cell carcinoma(OPSCC)is a malignant tumor originating from the squamous epithelium of the oro-pharyngeal mucosa,accounting for more than 90％of oropharyngeal malignancies.In recent years,human papillomavirus(HPV)infec-tion has become one of the primary etiological factors of oropharyngeal squamous carcinoma.The incidence of HPV-associated oropharyn-geal squamous carcinoma has been rising annually,with a noticeable trend toward younger populations,posing a significant threat to hu-man health.Due to the distinct biological behavior and clinical characteristics of HPV-associated oropharyngeal squamous carcinoma com-pared to its non-HPV-related counterpart,the diagnostic and treatment strategies for oropharyngeal squamous carcinoma have undergone substantial changes.Prevention and screening for oropharyngeal squamous carcinoma are of critical importance.The diagnostic and treat-ment process involves multi-disciplinary collaboration,including oral and maxillofacial surgery,otolaryngology,head and neck surgery,oncology,radiology and pathology.Based on evidence from clinical practice,a comprehensive,integrated diagnostic and therapeutic ap-proach has been established,centered around the concept of"prevention,screening,diagnosis,treatment,and rehabilitation",covering the entire patient lifecycle and providing a valuable reference for clinical practice.

Oral squamous cell carcinoma(OSCC)is a malignant lesion originating from the oral mucosal squamous epithelium,account-ing for over 80％of oral and maxillofacial malignancies.Key etiological factors include tobacco,alcohol abuse,and betel quid chewing.In China,its incidence has shown an overall upward trend,posing a significant threat to public health.OSCC exhibits high local invasive-ness,making early diagnosis critical for improving prognosis.Its clinical management requires close multidisciplinary collaboration among oral and maxillofacial surgery,head and neck surgery,radiation oncology,medical oncology,reconstructive surgery,radiology,patholo-gy,and nutritional support teams.Given the increasing disease burden of OSCC and rapid development of multidisciplinary collaborative models,an expert panel has formulated this integrated management consensus based on evidence-based medicine and extensive deliber-ation.Centered on the'Prevention-Screening-Diagnosis-Treatment-Rehabilitation'framework,the consensus provides comprehensive guidance for the entire disease course of OSCC patients,aiming to standardize clinical practice.

In recent decades,the incidence of human papillomavirus(HPV)-associated oropharyngeal squamous cell carcinoma(OPSCC)has shown a marked increase.Significant changes have also occurred in the OPSCC diagnosis and treatment paradigm.Deter-mining HPV status prior to treatment is now essential,and radiotherapy/chemotherapy,immunotherapy,and minimally invasive surgical techniques have progressively emerged as key modalities for managing OPSCC.However,alongside these paradigm shifts,a comprehen-sive technical consensus guiding the entire diagnostic and therapeutic process for OPSCC patients is currently lacking.Given China's large population base and the rising incidence of OPSCC,an expert panel convened to develop a clinical technical consensus on OPSCC diagno-sis and management tailored to China's specific context.This consensus aims to further enhance and standardize understanding of OPSCC management techniques among relevant healthcare professionals.

ObjectiveTo analyze the microbial diversity in the rhizosphere soil of Gastrodia elata with different yields and explore the influence of soil microorganisms on the yield of G. elata. MethodThe experiment adopted the 16S DNA and ITS high-throughput sequencing technologies to study the diversity of the bacterial and fungal community in the rhizosphere soil of G. elata with high yield （GC） and low yield （DC）. ResultProteobacteria， Firmicutes， and other unidentified Bacteria were dominant in the rhizosphere soil of G. elata. The dominant rhizosphere fungi were Ascomycota， Basidiomycota， and Mortierellomycota. There was no significant difference in microbial community abundance in the high-yield and low-yield rhizosphere soil of G. elata， but there was a significant difference in species composition. Thirty-eight microbes such as Bradyrhizobium， Schleiferilactobacillus， and Archaeorhizomyces were gathered in large numbers in the high-yield rhizosphere soil， and thirty microbes such as Fusarium， Coprinellus， and Nitrosotalea were gathered in large numbers in the low-yield rhizosphere soil. At the level of genus and species， there were six different species in the high-yield and low-yield rhizosphere soil of G. elata， among which Russula mariae， Archeaeorhizomyces， and Ilyonectria were gathered in the high-yield rhizosphere soil of G. elata， while Nitrosotalea， Coprinellus disserminatus， and Fusarium were gathered in the low-yield rhizosphere soil of G. elata. ConclusionThere are different microorganisms in the rhizosphere soil of G. elata with different yields， and it is speculated that these microorganisms are related to the yields of G. elata. The research results are expected to provide a vital theoretical basis for the follow-up study of the high yield of G. elata.

Objective To evaluate the safety and efficiency of the unibody bifurcate endografts in treating aortoiliac occlusive disease. Methods We performed a retrospective review of patients with aortoiliac occlusive disease who underwent endovascular revascularization with unibody bifurcated endografts. Data of demography, operative details, and outcomes were collected. Results From March 2016 to December 2017, 7 patients (6 males and 1 female) were treated using this endovascular technique. Technical success was achieved in all patients and there were no procedure related complications. The aortoiliac reconstructions remained patent within the median follow up of 11.0 (range 6.3-21.3) months, and all the patients clinically were improved an average of 1.71 Rutherford categories. Conclusions Endovascular repairment using an unibody bifurcated endograft for aortoiliac occlusive disease is feasible and effective, and has excellent short and midterm patency; however, the long?term patency need to be consequently observed.

Radiomics and radiogenomics are used to provide comprehensive tumor biological characte-ristics and further clinical information by extracting,screening and analyzing the most valuable quantitative ra-diomics features. In recent years,numerous studies have shown that radiomics plays a role in the diagnosis, treatment and predicting efficacy and prognosis of lung cancer. Radiogenomics shows a great value in the pre-diction of lung cancer gene phenotype and individualized precision treatment by combining radiomics features with genomics,proteomics and so on. Radiomics and radiogenomics are non-invasive,quantitative,and repro-ducible,and they can provide multidirectional tumor biological characteristics,which are expected to be widely used in the precise medical treatment of lung cancer in the future.

BACKGROUND:The main clinical manifestation of senile arteriosclerosis obliterans is lower limb ischemia, which is currently difficult to treat. One method is by autologous stem cell transplantation into the muscles of ischemic limbs to improve the formation of new capillaries and restore lower limb blood flow. Endothelial progenitor cell marker CD34+ cell transplantation has been shown to promote angiogenesis in ischemic limbs. Therefore, we propose that peripheral blood autologous CD34+ cell transplantation in older adult patients with atherosclerotic ischemia could effectively promote angiogenesis.OBJECTIVE:To assume that peripheral blood autologous CD34+ cell transplantation in the elderly with atherosclerotic ischemia could effectively promote angiogenesis.METHODS:This is a prospective, single-center, open-label, randomized, and controlled clinical trial that will be completed at the Qingdao No. 9 People's Hospital, China. Twenty older adult patients with atherosclerotic lower limb ischemia will be randomized into two groups. In the cell transplantation group (n=10), peripheral blood CD34+ cells transfected with vascular endothelial growth factor 165 (VEGF165) gene will be intramuscularly transplanted into the ischemic limbs in older adult patients with atherosclerotic lower limb ischemia. In the control group (n=10), normal saline will be intramuscularly injected into the ischemic limbs. All patients will be followed up for 6 months. The primary outcome will be ankle-brachial indices before and 6 months after transplantation to assess lower limb ischemia in both groups.The secondary outcomes will be the number of microvessels in the lower limb muscles before and 6 months after transplantation, the morphology of new blood vessels revealed by CT angiography, the number of VEGF-immunoreactive cells 6 months after transplantation and the incidence of adverse reactions. The trial was registered at the ClinicalTrials.gov (identifier:NCT03098771), and the study protocol was approved by the Ethics Committee of Qingdao No. 9 People's Hospital of China. All protocols will be in accordance with Declaration of Helsinki,formulated by the World Medical Association. All patients will be informed of study protocols and provide a written informed consent prior to the beginning of the trial.DISCUSSION:This trial will begin in January 2018 and finish in December 2019. We aim to quantify the effects of VEGF165 gene-modified CD34+ cell transplantation in the treatment of older adult patients with atherosclerotic ischemia to develop a new effective treatment of lower limb ischemia.
