Objective:To explore the application and key points of microchannel approaches in resec-tion of cervical intraspinal tumors.Methods:A retrospective analysis was performed on 51 cases of cervi-cal spinal canal tumors from February 2017 to March 2020.Among them,5 cases were located epidural space,6 cases were located epidural and subdural space,and 40 cases were located under the subdural extramedullary space(6 cases were located on the ventral side of the spinal cord).The maximum diameter ranged from 0.5 to 3.0 cm.The clinical manifestations included neck,shoulder or upper limb pain 43 cases,sensory disturbance(numbness)in 22 cases,and limb weakness in 8 cases.The micro-channel keyhole technique was used to expose the tumor,and the tumor was resected microscopically.Results:In this study,35 patients underwent hemilaminectomy,12 patients underwent interlaminar fenestration,2 patients underwent medial 1/4 facetectomy on the basis of hemilaminectomy or interlaminar fenestration.Two tumors were resected through anatomy space(no bone was resected).The degree of tumor resection included total resection in 50 cases and subtotal resection in 1 case.The type of the tumor included 36 schwannomas,12 meningiomas,2 enterogenic cysts and 1 dermoid cyst.There was no infec-tion and cerebrospinal fluid leakage postoperatively.Limb numbness occurred in 7 patients.The average follow-up time was 15 months(3 to 36 months).No deformity such as cervical instability or kyphosis was found.The tumor had no recurrence.Conclusion:The cervical spinal canal is relatively wide,cervical tumors with no more than three segments can be fully exposed by means of microchannel technology.Besides intramedullary or malignant tumors,they can be microsurgically removed.Preservation of the skeletal muscle structure of cervical spine is beneficial to recover the anatomy and function of cervical spine.The electrophysiological monitoring helps to avoid spinal cord or nerve root injury.

Objective To evaluate the value of miniprobe endoscopic ultrasound(EUS)in guiding endoscopic treatment of small-diameter(maximum diameter less than 1 cm)and low-grade(G1 grade)rectum neuroendocrine neoplasm(R-NEN),and to provide evidence and clues for its clinical application and further research.Methods The clinical data of 85 cases of low-grade(G1 grade)R-NEN with a maximum diameter of less than 1 cm who underwent endoscopic treatment in our center from January 2014 to December 2020 were retrospectively analyzed.The patients were divided into the EUS group(37 cases)and control group(48 cases)according to whether EUS was performed before endoscopic treatment.The positive rate of incision margin,the incidence of complications,the recurrence rate,the hospital stay,the cost of hospitalization and endoscopic therapy were compared between the two groups.Results The positive rate of incision margin in the EUS group was significantly lower than that in control group(P<0.05).There was no significant difference in the incidence of complications,tumor recurrence rate,hospital stay or hospital costs between the two groups(P>0.05).There was statistically significant difference in the endoscopic therapy between the two groups(P<0.05).Conclusion Evaluating the lesion depth of small-diameter and low-grade(G1 grade)R-NEN before surgery by miniprobe EUS and selecting endoscopic surgery according to its results of can significantly reduce the residual risk of resection margin tumors.

Osteoporotic proximal humeral fracture (OPHF) is one of the common osteoporotic fractures in the aged, with an incidence only lower than vertebral compression fracture, hip fracture, and distal radius fracture. OPHF, secondary to osteoporosis and characterized by poor bone quality, comminuted fracture pattern, slow healing, and severely impaired shoulder joint function, poses a big challenge to the current clinical diagnosis and treatment. In the field of diagnosis, treatment, and rehabilitation of OPHF, traditional Chinese and Western medicine have accumulated rich experience and evidence from evidence-based medicine and achieved favorable outcomes. However, there is still a lack of guidance from a relevant consensus as to how to integrate the advantages of the two medical systems and achieve the integrated diagnosis and treatment. To promote the diagnosis and treatment of OPHF with integrated traditional Chinese and Western medicine, relevant experts from Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine have been organized to formulate Expert consensus on the diagnosis and treatment of osteoporotic proximal humeral fracture with integrated traditional Chinese and Western medicine ( version 2024) by searching related literatures and based on the evidences from evidence-based medicine. This consensus consists of 13 recommendations about the diagnosis, treatment and rehabilitation of OPHF with integrated traditional Chinese medicine and Western medicine, aimed at standardizing, systematizing, and personalizing the diagnosis and treatment of OPHF with integrated traditional Chinse and Western medicine to improve the patients ′ function.

With the development of population aging, the incidence of lower limb artery ischemic diseases is gradually increasing. Although various treatments such as medication and endovascular surgery are currently available, patients with compromised microcirculation in the distal limbs and poor outflow pathways often do not achieve satisfactory results. Additionally, these treatments can be costly, and long-term patency rates are not ideal. The amendment in situ autologous great saphenous vein arterialization surgery utilizes the patient′s great saphenous vein to provide arterial blood in a retrograde manner and re-establishes blood supply to the tissues through the venous microcirculation system in the distal foot. This approach can achieve good limb salvage results and long-term patency. Therefore, this article aims to elaborate on the methods and value of amendment in situ autologous great saphenous vein arterialization surgery.

ObjectiveTo explore the syndrome elements and evolving patterns of patients with hepatitis B virus-related acute on chronic liver failure （HBV-ACLF） at different stages. MethodsClinical information of 1,058 hospitalized HBV-ACLF patients， including 618 in the early stage， 355 in the middle stage， and 85 in the late stage， were collected from 18 clinical centers across 12 regions nationwide from January 1， 2012 to February 28， 2015. The “Hepatitis B-related Chronic and Acute Liver Failure Chinese Medicine Clinical Questionnaire” were designed to investigate the basic information of the patients， like the four diagnostic information （including symptoms， tongue， pulse） of traditional Chinese medicine （TCM）， and to count the frequency of the appearance of the four diagnostic information. Factor analysis and cluster analysis were employed to determine and statistically analyze the syndrome elements and patterns of HBV-ACLF patients at different stages. ResultsThere were 76 four diagnostic information from 1058 HBV-ACLF patients， and 53 four diagnostic information with a frequency of occurrence ≥ 5% were used as factor analysis entries， including 36 symptom information， 12 tongue information， and 5 pulse information. Four types of TCM patterns were identified in HBV-ACLF， which were liver-gallbladder damp-heat pattern， qi deficiency and blood stasis pattern， liver-kidney yin deficiency pattern， and spleen-kidney yang-deficiency pattern. In the early stage， heat （39.4%， 359/912） and dampness （27.5%， 251/912） were most common， and the pattern of the disease was dominated by liver-gallbladder damp-heat pattern （74.6%， 461/618）； in the middle stage， dampness （30.2%， 187/619） and blood stasis （20.7%， 128/619） were most common， and the patterns of the disease were dominated by liver-gallbladder damp-heat pattern （53.2%， 189/355）， and qi deficiency and blood stasis pattern （27.6%， 98/355）； and in the late stage， the pattern of the disease was dominated by qi deficiency （26.3%， 40/152） and yin deficiency （20.4%， 31/152）， and the patterns were dominated by qi deficiency and blood stasis pattern （36.5%， 31/85）， and liver-gallbladder damp-heat pattern （25.9%， 22/85）. ConclusionThere are significant differences in the distribution of syndrome elements and patterns at different stages of HBV-ACLF， presenting an overall trend of evolving patterns as "from excess to deficiency， transforming from excess to deficiency"， which is damp-heat → blood stasis → qi-blood yin-yang deficiency.
