ABSTRACT
Proteus syndrome is a rare congenital hamartomatous syndrome characterized by the asymmetric and disproportionate overgrowth of limbs, emergence of connective tissue nevi, epidermal nevi, ysregulated adipose tissue, and vascular malformations. The Proteus syndrome is caused by mosaicism of somatic activating mutation in the AKT1 gene which locates at chromosome 14q32.3. This syndrome is extremely rare, making it difficult to diagnose. The most commonly used diagnostic criteria are too complicated to be used in clinical practice. Surgery can partially alleviate the clinical symptoms of overgrowth, but it can't inhibit the progression of the disease. This article summarizes the diagnostic criteria, treatment principles, and perioperative managements for Proteus syndrome in the world. The article proposes the highly suspected morphological manifestations of Proteus syndrome was based on clinical experiences of the author.The article emphasizes using genetic detection of pathological tissue as the gold standard for diagnosis, and suggests targeted therapy as the optimal treatment for Proteus syndrome.
ABSTRACT
Nail-patella syndrome (NPS) is a hereditary rare disease that can involve fingernail, patella, elbow, and iliac bones. In this article, we report a case of a girl-9 and 1 quarter years old who had asthmatic contractures in both elbows, thumbnail hypoplasia in both hands, patellar dislocation of both knees, iliac angle protrusion of both sides, and scoliosis. Whole exome sequencing suggests the presence of a LMX1B NM_002316.4:c.706G > C(p.Ala236Pro) mutation. NPS is an autosomal dominant disease associated with gene mutation of LMX1B, which can be diagnosed by combining the patient′s clinical manifestations and genetic results. The treatment now only targets on symptoms, relieving the localized severe lesion but not cure right now.
ABSTRACT
PIK3CA-related overgrowth spectrum (PROS) is a rare condition characterized by disproportionate overgrowth of head, neck, trunk, or extremity, caused by PIK3CA gene mutation. This condition has negative impact on the physical appearance, functions, and psychosocial well-being of the patients. The condition causes social and economic burden, too. The gold standard for the diagnosis of PROS is the genetic testing using somatic tissue, but detecting low-level mosaic mutations of PIK3CA gene remains a challenge. There is no specific treatment now. Supportive management including surgery and other interventions have limited effects in improving cosmetic outcome and functions. Multidisciplinary collaboration is the key to the success of managing PROS. Targeted gene therapy is promising in improving the outcome for patients with severe PROS. Patients diagnosed with negative genetics test by the clinical measures are often ineligible for novel gene therapy. This article reviews the clinical manifestations, diagnosis, and treatments of PROS, aiming to improve the current understanding of this rare condition.
ABSTRACT
Objective:To investigate the early and middle term clinical efficacies of 3D-printed metal prostheses in the reconstruction of bone defects after osteotomy in malignant bone tumors.Methods:A total of 34 patients with malignant bone tumors of lower extremity femur and tibia who underwent 3D printing individualized metal prosthesis replacement surgery in the Department of Bone and Soft Tissue of Affiliated Cancer Hospital of Zhengzhou University from March 2019 to March 2022 were retrospectively analyzed. There were 23 males and 11 females, with an average age of 19.1±15.2 years (range, 7-80 years). There were 22 children and adolescents younger than 18 years old. There were 3 cases in the proximal femur, 15 cases in the middle and distal femur, 10 cases in the proximal tibia and 6 cases in the distal tibia. According to the final pathological diagnosis, 24 cases of osteosarcoma, 6 cases of Ewing's sarcoma, 2 cases of undifferentiated sarcoma, 1 case of osteosarcoma, and 1 case of malignant giant cell tumor of bone were enrolled in this study. Postoperative complications, wound healing, periprosthetic fracture and aseptic loosening, tumor outcome (evaluated by tumor control evaluation criteria), and length difference of lower limbs were recorded. Response evaluation criteria in solid tumor (RECIST) was used to evaluate tumor outcomes. Prosthetic-bone interface healing was evaluated postoperatively, and the function was evaluated based on Musculoskeletal Oncology Society (MSTS) 93.Results:The length of lesions was 70-240 mm in 34 patients, with an average of 125.5±35.4 mm. The length of osteotomy was 80-275 mm, with an average of 160.2±33.9 mm. No tumor was found on the osteotomy surface. The customized prosthesis was firmly installed and closely matched with the side of the preserved articular surface. There were 2 patients with local incision fat liquefaction and 4 patients with superficial wound infection, which healed after debridement and antibiotic treatment. One distal tibia osteosarcoma case developed severe periprosthetic infection 2 months after surgery, resulting in prosthesis implantation failure, limb movement pain and poor ankle function. After removal of the prosthesis, infection control and osteogenesis with the Ilizarov technique, the infection was completely controlled and local osteogenesis was possible. The remaining 33 patients had a good prosthetic-bone interface union. One case was found to have localized bone resorption on the contact surface of the prosthesis 7 months after operation, but the metal prosthesis and screws were not loose. The incisions healed well in other patients, without infection, prosthesis loosening, fracture or other complications. All patients survived and were followed up for 13.8±5.6 months (range, 7-27 months). During the follow-up, there was no recurrence of tumor at the osteotomy end in all patients, but 5 patients developed lung metastasis. At the end of the last follow-up, all patients survived. Among them, 16 patients had unequal length of lower limbs, including 10 cases within 2 cm, 3 cases between 2-5 cm, and 3 cases over 5 cm. With the exception of one patient whose prosthesis was removed due to infection, the MSTS 93 of the other patients was 24.9±2.2 (range, 19-28), and were rated as excellent in 26 cases and good in 7 cases. According to the RECIST evaluation criteria, 26 of 34 patients had complete response, 5 had disease progression, and 3 had stable disease.Conclusion:3D printed metal prosthesis is one of the effective methods for the treatment of bone defects after resection of malignant bone tumors in lower limbs, which is safe, reliable and has satisfactory early curative effect.
ABSTRACT
Diabetic retinopathy(DR)is the most common microvascular complication of patients with diabetes mellitus, and it has become one of the leading causes of visual impairment among working-age people worldwide. The pathogenesis of DR is complicated with multiple mechanisms. Plenty of studies have indicated that circadian rhythm and clock genes are closely related to the pathogenesis of DR. Circadian rhythm is a physiological process regulated by clock genes, which takes 24h as a cycle and is consistent with the changes of light and dark outside. Circadian rhythm regulates various physiological activities of the body. The disturbance of circadian rhythm induces DR by affecting the blood glucose level and the physiological homeostasis of the eye in patients with diabetes mellitus, and clock genes may be involved in the pathogenesis of DR by regulating oxidative stress response, inflammatory response, retinal autophagy rhythm, mitochondrial dysfunction and endothelial progenitor cell function. This paper will introduce the generation and regulation mechanism of circadian rhythm, as well as the internal circadian rhythm of retina, and further discuss the influence of circadian rhythm and clock genes on the occurrence and development of DR, aiming to provide a reference for the prevention and treatment of DR.
ABSTRACT
OBJECTIVE@#To screen better promoters and provide more powerful tools for basic research and gene therapy of hemophilia.@*METHODS@#Bioinformatics methods were used to analyze the promoters expressing housekeeping genes with high abundance, so as to select potential candidate promoters. The GFP reporter gene vector was constructed, and the packaging efficiency of the novel promoter was investigated with EF1 α promoter as control, and the transcription and activities of the reporter gene were investigated too. The activity of the candidate promoter was investigated by loading F9 gene.@*RESULTS@#The most potential RPS6 promoter was obtained by screening. There was no difference in lentiviral packaging between EF1 α-LV and RPS6-LV, and their virus titer were consistent. In 293T cells, the transduction efficiency and mean fluorescence intensity of RPS6pro-LV and EF1 αpro-LV were proportional to the lentiviral dose. The transfection efficiency of both promoters in different types of cells was in the following order: 293T>HEL>MSC; Compared with EF1 αpro-LV, RPS6pro-LV could obtain a higher fluorescence intensity in MSC cells, and RPS6pro-LV was more stable in long-term cultured HEL cells infected with two lentiviruses respectively. The results of RT-qPCR, Western blot and FIX activity (FIX∶C) detection of K562 cell culture supernatant showed that FIX expression in the EF1 α-F9 and RPS6-F9 groups was higher than that in the unloaded control group, and there was no significant difference in FIX expression between the EF1 α-F9 and RPS6-F9 groups.@*CONCLUSION@#After screening and optimization, a promoter was obtained, which can be widely used for exogenous gene expression. The high stability and viability of the promoter were confirmed by long-term culture and active gene expression, which providing a powerful tool for basic research and clinical gene therapy of hemophilia.

ABSTRACT
Objective:To investigate the risk factors of cervical lymph node metastasis (LNM) and survival analysis in patients with medullary thyroid carcinoma (MTC) .Methods:93 patients with MTC admitted to the Department of General Surgery and Department of Otorhinolaryngology, First Medical Center of PLA General Hospital from Sep. 2008 to Aug. 2020 were analyzed retrospectively, including 45 males and 48 females, with an average age of 47 years old. SPSS 26.0 statistical software was used for data processing of the initial surgical year and procedures, tumor pathological stages, preoperative calcitonin (Ctn) level, preoperative carcinoembryonic antigen (CEA) level, LNM status, recurrence free survival (RFS) , etc. The risk factors of LNM and prognosis of MTC patients were analyzed by COX univariate and multivariate regression. Kaplan Meier method was used to estimate the survival rates of independent risk factors affecting prognosis and draw their survival curves.Results:The median follow-up time of 93 patients was 53 months, ranging from 2 to 192 months. The 1-year, 3-year, 5-year and 10-year survival rates were 97.8%, 96.6%, 94.6% and 88.9% respectively. Multivariate COX regression analysis showed that Initial surgical procedures ( P=0.018) and preoperative Ctn level ( P=0.012) were independent risk factors of central cervical LNM. Preoperative Ctn level ( P=0.028) and Capsule invasion ( P=0.024) were the independent risk factors of lateral cervical LNM. Preoperative Ctn level≥180.30 pg/ml and ≥234.15pg/ml indicated central and lateral cervical LNM respectively (all P<0.001) . Distant metastasis was an independent risk factor of RFS ( P=0.037) of MTC. Conclusions:Standardized surgical procedures are recommended for initial treatment of MTC, which can reduce the possibility of residual occult metastasis and the risk of reoperation. Distant metastasis affects prognosis of MTC.
ABSTRACT
In this study, black phosphorus nanosheets (BP) were prepared by the ordinary liquid phase method, and resveratrol was loaded on the BP after being modified by polyethylene glycol. The brain targeting of BP was investigated by fluorescent protein labeling, and the effects of black phosphorus on cerebral ischemia/reperfusion injury were studied by 2,3,5-triphenyltetrazolium chloride (TTC) staining, neurobehavioral evaluation, and brain edema. Protein immunoblotting analysis was used to explore the molecular mechanism of the BP drug delivery system on ischemic brain injury. Hemolysis test and hematoxylin-eosin (H&E) staining were used to evaluate its biocompatibility. The results showed that BP had excellent drug loading capacity, uniform drug loading system structure and particle size, stable drug release curve, and excellent photothermal effect. Through the analysis and comparison of fluorescence intensity, it was found that BP can increase the permeability of blood-brain barrier (BBB) under the condition of near-infrared light assisted irradiation, and make drugs more pass through the BBB. In addition, the black phosphorus nano tablet drug delivery system can significantly improve the neurobehavioral disorder of mice after modeling, and the cerebral infarction area and brain edema degree are significantly decreased. Western blot experiments showed that the drug delivery system could play an anti-ischemic brain injury role by activating the expression of antioxidant signaling pathway proteins nuclear factor E2-related factor 2 (Nrf2) and heme oxygenase-1 (HO-1). The hemolysis test and H&E test results of the BP drug carrier system showed that it had no obvious toxicity and high safety. In conclusion, the BP prepared in this study had high drug loading, good photothermal performance, and high safety. Under the near-infrared condition, they also have certain brain targeting ability, which can improve the therapeutic effect of drugs in the brain. Animal welfare and experimental procedures were following the regulations of the Animal Ethics Committee of the First Affiliated Hospital of Shihezi University.

Arterial stiffness plays a major role in the pathogenesis of numerous age-related diseases.Pulse wave velocity, distensibility, wave reflection, and pulse pressure are used to assess arterial stiffness, but the features and clinical significance of each parameter are different.Combined application of these parameters can comprehensively evaluate arterial stiffness.This review summarizes the methods and research progress of noninvasive assessment of arterial stiffness.
ABSTRACT
OBJECTIVES@#This study aimed to assess the influence of different types of rapid maxillary expansion on root resorption (RR).@*METHODS@#Literature searches were carried out electronically in five English and two Chinese databases. Randomized controlled trials (RCTs), controlled clinical trials (CCTs), cohort studies, and case-control studies were included. The data were extracted by three authors. The risk of bias in the RCTs and nonrandomized studies were assessed in accordance with corresponding scales.@*RESULTS@#Among the 400 articles identified, seven were included for the final analysis. Three studies were graded as high value of evidence, while two and another two studies were graded as moderate value and low value, respectively. According to the available evidence, the tooth-borne maxillary expansion caused more obvious RR of anchorage teeth than the bone-borne one. In addition, the Haas-type palatal acrylic pads could not effectively reduce the degree of RR. The difference in the design of the retainer between the tooth-borne maxillary expansion (the use of a band or wire framework to connect the anchorage tooth) did not cause the difference in the incidence and degree of RR.@*CONCLUSIONS@#Clinical evidence suggested that bone-borne maxillary expansion may decrease the amount of RR, while the amounts of resorption did not significantly differ between Haas and Hyrax and between different retainer types of Hyrax.

Objective:To investigate the infiltration of immune cells and prognosis in papillary thyroid carcinoma (PTC) with cervical lymph nodes metastases.Methods:The RNA-seq data and clinicopathological data of PTC patients were downloaded from the Cancer Genome Atlas (TCGA) database. There were 85 patients in the PTC with cervical lymph nodes metastases group and 23 patients in the control group, according to the inclusion and exclusion criteria. CIBERSORT deconvolution algorithm was used to calculate the infiltration ratio of 22 kinds of immune cells in PTC with cervical lymph nodes metastases. Different immune infiltrating cells were compared between PTC with cervical lymph nodes metastases and normal thyroid. The correlation between clinical characteristics (age, gender, extra-thyroid invasion and TNM stage) and infiltration of immune cells were evaluated, then different immune cells related to the prognosis of PTC with cervical lymph nodes metastases patients were screened by Kaplan-Meier analysis.Results:The B cells naive, B cells memory, T cells CD8, macrophages M1, mast cells activated and eosinophils were down-regulated in tumor tissue compared with normal. Macrophages M0, macrophages M2, dendritic cells resting, dendritic cells activated and mast cells resting were higher in tumor tissue compared with that of normal. Macrophages M0, macrophages M2 and dendritic cells resting were positively correlated with extra-thyroid invasion and TNM stage, and patients with a high proportion of those immune cells had a shorter progression-free survival (PFS) . The B cells naive and T cells CD8 were negatively correlated with extra-thyroid invasion and TNM stage, and patients with a high proportion of those immune cells had a longer progression-free survival (PFS) .Conclusions:The pattern of immune cell infiltration of PTC with cervical lymph nodes metastases has specificity, and it was related to clinical characteristics and prognosis. This study provides theoretical evidences and new insights for the role of immune cell microenvironment in PTC lymph node metastasis.
ABSTRACT
Objective:To investigate the epidemiological and clinicopathological characteristics of thyroid cancer.Methods:Data of 13 673 thyroid cancer patients admitted to the First Medical Center of PLA General Hospital from Jan. 2014 to Dec. 2019 were retrospectively analyzed. According to the admission criteria, 9 662 patients were screened out, including 2 768 males and 6 894 females, with an average age of 43.98±11.28 years. According to the year of diagnosis and treatment, the incidence of thyroid cancer, the changing trend of age of new cases, the average length of hospitalization, the pathological classification of the tumor, the size of the primary tumor, multifocal tumor, and the rate of lymph node metastasis were statistically analyzed. The surgical methods were summarized and discussed.Results:① Characteristics of population economics: the ratio of males to females were 1.00:2.49, the number of cases increased year by year, and the rate of increase of female was higher than that of male. The average age of onset of the patients was (43.98±11.28) years old, and the incidence rate of the young population increased by 6.0%, showing a younger trend. The mean length of hospital stay was (7.21±2.85) d, and the length of hospital stay decreased. ② Clinicopathological features: There were 9 513 cases of papillary thyroid carcinoma (PTC) (98.46%) , 45 cases of follicular thyroid carcinoma (FTC) (0.47%) , 58 cases of medullary carcinoma (MTC) (0.60%) and 18 cases of poorly differentiated thyroid carcinoma (PDTC) (0.19%) . There were 2 cases (0.02%) of undifferentiated thyroid carcinoma (ATC) and 26 cases (0.26%) of a particular type. The tumor size was (1.10±0.85) cm, among which the microcarcinoma (D ≤1 cm) accounted for 64.5% and showed an increasing trend year by year, with the fastest growth rate. There were 3 809 cases of multifocal carcinoma (39.4%) , and the proportion of multifocal carcinoma increased year by year in recent 3 years. The central region and lateral region lymph node metastasis rates were 33.0% and 13.0%, respectively. Correlation analysis showed that the differences were statistically significant except for pathological types ( P<0.05) . ③ Surgical methods: in the first 3 years, 2 224 patients (84.2%) underwent normative primary resection, which increased to 94.9% in the last 3 years. In the first 3 years, 2 033 patients (77.0%) underwent central lymph node dissection, which increased to 91.8% in the last 3 years. In the first 3 years, 188 cases (50.5%) underwent normative lateral cervical dissection, which increased to 71.6% in the last 3 years. Conclusions:The incidence of thyroid cancer is increasing year by year, showing a younger trend; Papillary carcinoma accounts for 98.5% of thyroid cancer. The proportion of microcarcinoma and multifocal carcinoma is increasing. The rate of lymph node metastasis in the central region and lateral region is increasing; surgery is gradually standardized, and it is necessary to standardize the diagnosis and treatment of thyroid cancer and postoperative follow-up.
ABSTRACT
Objective:To investigate the prognostic factors and pathological characteristics of mixed subtype thyroid cancer (MSTC) .Methods:Data of 41 cases of MSTC, which were confirmed by postoperative pathology, among from 24, 912 cases of thyroid cancer admitted in Mar. 2005 to Aug. 2020 in the First Medical Center of Chinese People’s Liberation Army General Hospital, were retrospectively analyzed. 37 cases underwent surgical treatment, while 4 cases only underwent puncture to confirm the pathology due to physical conditions, and no surgical treatment was performed. The tumor size, number of lesions, capsule invasion, AJCC 8th TNM staging, surgical methods, radiotherapy and chemotherapy were collected. The MSTC patients in the group were followed up to obtain the postoperative situation. SPSS 25.0 and R studio statistical software was used for data processing, and Cox single factor and multivariate regression were used to analyze independent risk factors.Results:In the 41 cases, there were 9 cases of papillary carcinoma (PTC) mixed with follicular carcinoma (FTC) , and 8 cases of mixed medullary and follicular carcinoma (MMFTC) . There were 15 cases of poorly differentiated thyroid cancer (PDTC) , 4 cases of squamous cell carcinoma of thyroid (SCCT) , and 5 cases of undifferentiated thyroid carcinoma (ATC) . The median follow-up time was 18 months, and 11 patients died during the follow-up, with a mortality rate of 26.8%. Average onset age was (51.41+15.69) years. 4 cases had postoperative recurrence during the follow-up, including 2 cases of local recurrence, and 2 cases of distant metastasis. Single factor results showed that age, degree of tumor differentiation, surgical method, radiotherapy and chemotherapy were the risk factors affecting the prognosis of patients with MSTC ( P<0.05) . Multivariate analysis showed that age at diagnosis ( P=0.007) and surgical procedure ( P=0.017) were independent risk factors for prognosis in patients with MSTC. Conclusion:Middle-aged and elderly women are at high risk for MSTC, and the degree of tumor differentiation is proportional to survival. Due to the multi-type and pleomorphic pathological findings, a reasonable treatment plan has good effects on prognosis of MSTC.
ABSTRACT
With the increasing number of complex and difficult thyroid cancer patients, the traditional medical model is difficult to solve the problem of diagnosis and treatment of patients optimally. In recent years, multidisciplinary team (MDT) model is applied clinically. For complex and difficult thyroid cancer diseases, the model can play a multidisciplinary advantage and provide more personalized and accurate diagnosis and treatment scheme for patients. The diagnosis and treatment of complex and difficult thyroid cancer involve thyroid surgery, otolaryngology, thoracic surgery, anesthesiology, endocrinology, nuclear medicine, radiotherapy, oncology, ultrasound, imaging, pathology and other disciplines. Based on the important role of MDT in diagnosis, treatment, nursing, postoperative management and clinical research of thyroid cancer, as well as the challenges and difficulties faced in implementation of MDT, the status and progress of multi-disciplinary comprehensive diagnosis and treatment of thyroid cancer will be systematically elaborated in the paper.
ABSTRACT
Liver fibrosis is a pathological process characterized by excess deposition of extracellular matrix (ECM) that are mainly derived from activated hepatic stellate cells. Previous studies suggested that ligustroflavone (LF) was an ingredient of Ligustrum lucidum Ait. with activities of anti-inflammation and anti-oxidation. In this study, we investigated whether LF had any effect on liver fibrosis. In our study, we established a mouse model of carbon tetrachloride (CCl
ABSTRACT
OBJECTIVE@#To compare the clinical effect on intestinal dysfunction of spinal cord injury (SCI) between the comprehensive therapy of moxibustion (moxibustion for opening the governor vessel and regulating the spirit) and rehabilitation training and the simple treatment with rehabilitation training.@*METHODS@#A total of 60 patients with intestinal dysfunction of SCI were randomized into a comprehensive therapy group and a rehabilitation group, 30 cases in each one (3 cases were dropped out in each group). On the base of the routine western medicine treatment and rehabilitation training, the bowel training and rectal function training were provided, once a day in the rehabilitation group. In the comprehensive therapy group, on the base of the treatment as the rehabilitation group, the moxibustion was exerted at Yaoyangguan (GV 3), Mingmen (GV 4), Zhiyang (GV 9), Dazhui (GV 14) and Baihui (GV 20), etc, once a day, 30 min each time. In both groups, the treatment for 4 weeks was as one course and 3 courses of treatment were required. Separately, before treatment, after 4, 8 and 12 weeks of treatment, the scores of neurogenic bowel dysfunction (NBD) and World Health Organization quality of life scale (WHOQOL-BREF) were observed and the clinical effect was evaluated after 12 weeks of treatment.@*RESULTS@#After treatment, the total effective rate was 88.9% (24/27) in the comprehensive therapy group, which was higher than 74.1% (20/27) in the rehabilitation group (<0.05). After 4, 8 and 12 weeks of treatment, NBD scores were all reduced obviously as compared with those before treatment in the two groups (all <0.01). After 8 and 12 weeks of treatment, NBD scores in the comprehensive therapy group were lower than the rehabilitation group (both <0.05). After 4, 8 and 12 weeks of treatment, the scores of all of the domains (psychology, physiology, social relations and environment) in WHOQOL-BREF were higher than those before treatment in the two groups (all <0.01). After 4 weeks of treatment, the scores in the psychology and physiology domains in the comprehensive therapy group were higher than the rehabilitation group (all <0.05). After 8 and 12 weeks of treatment, the scores of all of the domains in the comprehensive therapy group were higher than the rehabilitation group (all <0.05).@*CONCLUSION@#The comprehensive treatment of moxibustion and rehabilitation training achieves the better effect on intestinal dysfunction of SCI than the simple rehabilitation training and greatly improves the quality of life in SCI patients.

OBJECTIVE@#To investigate the effects of IRF1 on the homeostasis and differentiation of K562 cells.@*METHODS@#Three different vectors were constructed to screen the best strategy for IRF1 overexpression. The effect of IRF1 on cell proliferation and apoptosis was explored by cell count and apoptotic surface marker detection. Likely, the effect of IRF1 on cell differentiation was analyzed by differentiational surface marker assay. Finally, the regulation mechanism at mRNA level was analyzed by RT-qPCR.@*RESULTS@#The single open reading frame constructed by P2A-T2A element showed the highest expression intensity, and it was the best approach to realize IRF1 enhancement. Cell counts showed that IRF1 had no significant effect on the proliferation of K562. Annexin V and 7-AAD labeling exhibited strong anti-apoptotic function of IRF1 against AraC induction. Flow cytometry revealed that IRF1 overexpression could also further increase the proportion of CD71CD235a cells. RT-qPCR confirmed its upregulation effect on CD235a and TAL1.@*CONCLUSION@#IRF1 enhancement alters the homeostasis characteristics of K562 cells, increases the anti-apoptotic ability and raises the potential to downstream differentiation, suggesting that IRF1 may play an important regulatory role in the hematopoietic development, including erythropoiesis.
ABSTRACT
In recent years, with the rising incidence of thyroid cancer and the improvement of medical standards, the pathological types of thyroid cancer have been refined and improved. It is found in clinical work that a small number of patients’ tumors are not limited to a single pathological type, but that two or more pathological subtypes of the same patient are mixed together. This type is called mixed subtype thyroid cancer (MSTC) , whose cytology is diverse and complex, is highly dependent on the results of postoperative pathological examination. At present, there are few studies on MSTC diagnostic criteria, auxiliary examinations and treatment options. Therefore, the case characteristics and clinical diagnosis and treatment of this subtype of thyroid cancer are a new direction of exploration. This article reviews study of MSTC from the aspects of definition, disease characteristics, and auxiliary examinations, and explores the progress of MSTC diagnosis and treatment research, providing a new perspective for the clinical diagnosis and treatment of this type of disease for clinical reference.
ABSTRACT
We retrieved the PDTC patient medical record in our center who have received multi-disciplinary comprehensive treatment in March 2019. By reviewing his treatment process, we hope to improve the recognition of this disease and provide reference for individualized programs.
