RESUMO
Objective: To explore the clinical characteristics of neutrophil extracellular trap (NET) in patients with severe cerebral venous sinus thrombosis (CVST) and to study their prognostic value in the acute and subacute phases. Methods: This study is a retrospective case series analysis. Clinical and pathological data of 52 patients with severe cerebral venous sinus thrombosis who underwent endovascular treatment in the Department of Neurosurgery, Tianjin Huanhu Hospital from June 2019 to June 2022 were retrospectively analyzed. There were 20 males and 32 females, with an age of (40.1±13.6) years(range:18 to 66 years). Forty-five healthy physical examinees were included in the control group. High-resolution MRI was used to stage the thrombus, with 11 cases in the acute group, 28 cases in the subacute group, and 13 cases in the chronic group. Thrombus specimens were obtained through endovascular treatment, and the fluorescence intensity of NET in peripheral blood at different time points was analyzed by immunofluorescence contrast,including the double-stranded DNA structure and adhesion protein components (citrolinated histone H3 (CitH3), myeloperoxidase-DNA complex(MPO-DNA), neutrophil elastase (NE)). The NET markers were determined by ELISA. Spearman rank correlation analysis was used to analyze the correlation between the NET markers in peripheral blood of patients with severe cerebral venous sinus thrombosis in the acute and subacute phases and the volume of venous sinus thrombus, the degree of venous sinus recanalization after treatment, and the discharge modified Rankin scale(mRS)score. The accuracy of NET markers in predicting the prognosis of patients with severe cerebral venous sinus thrombosis was analyzed by drawing receiver operating characteristic (ROC) curve and calculating the area under the curve (AUC). Results: The results of immunofluorescence staining and ELISA showed that no NET structure was formed in the peripheral blood of the control group, while CitH3, MPO-DNA and NE levels in the peripheral blood of CVST patients were increased, among which the acute stage group was the highest, followed by the subacute group, and the chronic group was the lowest. Spearman correlation analysis showed that CitH3, MPO-DNA and NE levels in peripheral blood of patients in acute group and subacute group were positively correlated with thrombus volume and mRS score at discharge (P<0.05). The levels of CitH3 and MPO-DNA in peripheral blood of patients with complete venous sinus recanalization were lower than those of patients with partial venous sinus recanalization (P<0.01). ROC curve analysis results showed that MPO-DNA and NE had no predictive ability for the prognosis of CVST patients (P values were 0.614 and 0.324, respectively), and the AUC of CitH3 was 0.800 (95%CI: 0.638~0.962, P=0.032), the best cut-off value was 13.5 µg/L, the sensitivity was 100%, and the specificity was 58.8%. Conclusions: A large number of NET are formed in patients with severe cerebral venous sinus thrombosis in acute stage. Patients with severe cerebral venous sinus thrombosis in acute stage and subacute stage with high peripheral blood NET content has a low rate of complete sinus revascularization and poor neurological function recovery after treatment.

Objective: To analyze the treatment outcomes and prognoses of children with head and neck non-parameningeal rhabdomyosarcoma (HNnPM RMS). Methods: A retrospective analysis was performed on the clinical data of children with HNnPM RMS admitted to Beijing Children's Hospital from September 2012 to September 2022. The clinical features, comprehensive treatment modes and prognoses of the patients were analyzed. The overall survival rate (OS) and event free survival rate (EFS) were calculated using the Kaplan-Meier method, and univariate analysis was performed using the Log-rank test. Results: A total of 70 children were included in this study, 38 males and 32 females, with a median age of 47 months (2-210 months). Pathological subtypes including the embryonal in 27 cases, the alveolar in 36 cases and the spindle cell and sclerosing in 7 cases. Thirty children (83.3%) with alveolar type were positive for FOXO1 gene fusion. All 70 children underwent chemotherapy, including 38 with neoadjuvant chemotherapy and 32 with adjuvant chemotherapy. Sixty of 70 children underwent surgery, of whom, 10 underwent two or more surgeries. There were 63 children underwent radiotherapy, including 54 with intensity-modulated radiation therapy, 4 with particle implantation and 5 with proton therapy. The median follow-up was 45 (5-113) months, the 5-year OS was 73.2%, and the 5-year EFS was 57.7%. Univariate analysis showed lymph node metastasis (χ2=5.022, P=0.025), distant metastasis (χ2=8.258, P=0.004), and high Intergroup Rhabdomyosarcoma Study (IRS) group (χ2=9.859, P=0.029) as risk factors for poor prognosis. Before June 2016, the 5-year OS based on BCH-RMS-2006 scheme was 63.6%, and after 2016, the 5-year OS based on CCCG-RMS-2016 scheme was 79.6%. Conclusion: Multidisciplinary combined standardized treatment can offer good treatment outcome and prognosis for children with HNnPM RMS. Local control is a key to the efficacy of comprehensive treatment.

Objective: To understand the epidemiological characteristics of public health emergency events (PHEE) of varicella in China from 2006 to 2021 and related response performances. Methods: The data of varicella PHEE in 31 provinces of China from 2006 to 2021 were collected through the Public Health Emergency Management Information System, Microsoft Excel 2019 software and SPSS 26.0 statistical software were used to conduct descriptive epidemiological, statistical analysis on the time, area, location distribution, scale and epidemic management. Results: A total of 11 443 PHEE involving 341 048 related cases were reported from 2006 to 2021, with an annual attack rate of 1.78%-3.80% and a total attack rate of 2.33% (341 048/14 624 042). The number of PHEE and related cases of varicella decreased from 1 107 (35 349) in 2007 to 262 (6 884) in 2012 (Z=-2.40, P<0.001), then increased year by year to 1 318 (42 649) in 2019 (Z=2.58, P<0.001), with a significant decline since 2020. The varicella PHEE in China presents the seasonal characteristics,the peak is from April to June and from October to December, respectively. The sub-peak of varicella PHEE in eastern China generally appears 1-2 months earlier than in central and western China. Varicella PHEE reports are mainly distributed in eastern China, the attack rate is relatively high in western China, school-reported varicella PHEE was 88.26% of the total reports (10 099/11 443). The epidemic scale of varrcella PHEE typically range from 10 to 29 cases per year among the given outbreaks. The M (Q1, Q3) of average number of cases, average duration, and average reporting interval of PHEE were 23 (16,35), 20 (14, 26) days, and 9 (5,19) days, respectively, and the reporting interval was positively correlated with the duration (r=0.854, P<0.001). Conclusions: The varicella PHEE in China from 2006 to 2021 has not been effectively controlled. Schools are the key places to prevent and control varicella PHEE. Improving the sensitivity of varicella PHEE monitoring, strengthening the timely disposal of varicella epidemic, and promoting varicella vaccination are effective measures to prevent and control varicella PHEE.

Objective: To investigate the clinical features, diagnosis, prognosis of malignant mesothelioma of the tunica vaginalis testis (MMTVT). Methods: The clinicopathological data of 7 patients with MMTVT who treated at Sun Yat-sen University Cancer Center between January 2010 and October 2022 were retrospectively reviewed. Cases were first diagnosed at (M (IQR)) 49 (23) years old (range: 27 to 64 years old). The main clinical manifestations were scrotal enlargement (7 cases) and hydrocele (2 cases). Results: Three patients underwent radical orchiectomy as initial treatment, 2 cases underwent hydrocelectomy due to diagnosis of hydrocele, followed by radical orchiectomy at Sun Yat-sen University Cancer Center, and 2 cases underwent transscrotal orchiectomy. Common tumor markers of testicular cancer were not significantly elevated in MMTVT. The expression of tumor PD-L1 was positive in 2 out of the 3 cases. One patient received adjuvant chemotherapy and 2 patients received first-line chemotherapy after tumor recurrence. Chemotherapy regimens used include cisplatin+pemetrexed. Up to October 2022, 3 cases relapsed, of which 2 cases died. The median overall survival was 35 months (range: 4 to 87 months) and the median progression-free survival was 6 months (range: 2 to 87 months). Conclusions: MMTVT at early stage should be treated with early radical orchiectomy and followed up closely after surgery. The cisplatin+pemetrexed regimen is a common option for the treatment of metastatic MMTVT, while whether immune checkpoint inhibitors could serve as a second-line treatment option deserves further research.

To discuss the effect of varicella vaccination on the clinical characteristics of herpes zoster (shingles) cases aged 20 years and under, and analyze its clinical features. Based on the Yichang Health Big Data Platform, a descriptive study was conducted to collect the information of cases aged 20 years and under in three medical institutions of Yichang Central People's Hospital, Yichang First People's Hospital and Yichang Second People's Hospital from March 2019 to September 2020. According to the history of varicella vaccine, cases were divided into vaccination group and non-vaccination group, and their clinical features and outcomes were compared. The results showed that 46 shingles cases, aged from 7 to 20 years old, were included in this study. 26 males (56.5%), 20 females (43.5%), 15 cases in vaccination group (32.6%) and 31 cases in non-vaccination group (67.4%). 28 cases had thoracic involvement, followed by lumbar (n=8), cranial (n=7) involvements and extremities (n=7). The spread of herpes skin area: 2 cases involved too large area, 21 cases of 10 cm×10 cm, 14 cases of 5 cm×5 cm, 9 cases of 1 cm×1 cm. Herpes number: 26 cases had 10-49 herpes, followed by <10 herpes (n=9), uncountable herpes (n=7) and 50-99 herpes (n=4). The clinical course[M(Q1,Q3)] lasted 20.5 (13.5,24.8) d averagely, 5 cases had postherpetic neuralgia (PHN) and 1 case had respiratory complications. Shingles decrustation time was significantly shorter in vaccination group (Z=-2.01, P<0.05), and there was no significant difference in other characteristics by vaccination. In conclusion, the number and spread of shingles in most children and adolescents are less, and the complications such as PHN are less. Varicella vaccination can reduce the decrustation time and relieve shingles cases with some clinical symptoms.

We studied the effect of fibroblast growth factor receptor 3 (FGFR3) inhibitor BGJ-398 on the differentiation of bone marrow mesenchymal stem cells (BM MSC) into osteoblasts in wild type (wt) mice and in animals with mutation in TBXT gene (mt) and possible differences in the pluripotency of these cells. Cytology tests showed that the cultured BM MSC could differentiate into osteoblasts and adipocytes. The effect of different BGJ-398 concentrations on the expression of FGFR3, RUNX2, SMAD1, SMAD4, SMAD5, SMAD6, SMAD7, and SMAD8 were studied by quantitative reverse transcription PCR. The expression of RUNX2 protein was evaluated by Western blotting. BM MSC of mt and wt mice did not differ in pluripotency and expressed the same membrane marker antigens. BGJ-398 inhibitor reduced the expression of FGFR3 and RUNX2. In BM MSC from mt and wt mice have similar gene expression (and its changing) in FGFR3, RUNX2, SMAD1, SMAD4, SMAD5, SMAD6, SMAD7, and SMAD8 genes. Thus, our experiments confirmed the effect of decreased expression of FGFR3 on osteogenic differentiation of BM MSC from wt and mt mice. However, BM MSC from mt and wt mice did not differ in pluripotency and are an adequate model for laboratory research.

RESUMO
Objective: To investigate the application and clinical efficacy of ultrasound debridement method in residual burn wounds. Methods: A retrospective cohort study was conducted. From August 2017 to August 2021, 64 patients with residual burn wounds who met the inclusion criteria were admitted to the 980th Hospital of the Joint Logistic Support Force of PLA. According to the debridement method adopted for the residual wounds, the patients were divided into ultrasound debridement group (34 cases, 22 males and 12 females, aged (31±13) years) and traditional debridement group (30 cases, 19 males and 11 females, aged (32±13) years). After the corresponding debridement, the wounds of patients in the two groups were selected for stamp skin grafting or large skin grafting according to the wound site and skin donor status. For unhealed wounds after stage â surgery, secondary debridement and skin grafting were be performed, with the wound debridement methods in the 2 groups being the same as those of stage â , respectively. On postoperative day 3, drug-sensitive test was used to detect the bacteria in the wound and the positive rate of bacteria was calculate. On postoperative day 7, the survival rate of skin slices in wound and the incidence of subcutaneous hematoma were calculated. At discharge, wound healing time and debridement times of patients were counted, and the secondary debridement rate was calculated. Data were statistically analyzed with independent sample t test or chi-square test. Results: On postoperative day 3, the wounds in ultrasound debridement group were infected with Staphylococcus aureus in 2 cases and Pseudomonas aeruginosa in 2 cases, and the wounds in traditional debridement group were infected with Staphylococcus aureus in 5 cases, Pseudomonas aeruginosa in 3 cases, Acinetobacter baumannii in 1 cases, Klebsiella pneumoniae in 1 cases, and Enterobacter cloacae in 1 cases. The positive rate of bacteria of wound in ultrasound debridement group was significantly lower than that in traditional debridement group (χ2=5.51, P<0.05). On postoperative day 7, the survival rate of skin grafts in ultrasound debridement group was (92±5) %, which was significantly higher than (84±10) % in traditional debridement group (χ2=6.78, P<0.01); the incidence of subcutaneous hematoma in ultrasound debridement group was 17.6% (6/34), which was significantly lower than 40.0%( 12/30) in traditional debridement group, χ2=3.94, P<0.05. At discharge, the wound healing time in ultrasound debridement group was (11.0±2.0) d, which was significantly shorter than (13.0±3.1) d in traditional debridement group (t=3.81, P<0.01); the secondary debridement rate of wounds in ultrasound debridement group was 2.9% (1/34), which was significantly lower than 20.0% (6/30) in traditional debridement group (χ2=4.76, P<0.05). Conclusions: Ultrasound debridement method can significantly reduce the bacterial load of residual burn wounds, reduce postoperative hematoma formation, and promote the survival of skin grafts to shorten the course of disease of patients.

Objective: To investigate the clinical features of obesity indicators in patients with endometrial atypical hyperplasia (EAH) and early endometrial cancer (EC) and analyze the relationship between these indexes and effect of fertility preservation therapy. Methods: The clinical data of patients with EAH, EC and endometrial benign lesions treated in Peking University People's Hospital from January 1, 2018 to June 30, 2021 who required fertility-sparing treatment were collected, and obesity indicators were calculated and analyzed retrospectively. Results: (1) Obesity indicators: the obesity [body mass index (BMI) ≥28 kg/m2] rate of patients with fertility preservation treatment was 40% (32/80), and abdominal obesity [waist circumference (WC) ≥80 cm] rate was 79% (63/80), and obesity indicators [BMI, WC, waist-hip ratio (WHR), weight height ratio (WHTR), body roundness index (BRI), lipid accumulation index (LAP), visceral adiposity index (VAI)] were higher than those with endometrial benign lesions (all P<0.001). (2) Related factors affecting the efficacy of fertility preservation treatment and their predictive value: EC, higher BMI, WC, WHR, WHTR and BRI were risk factors for lower complete remission rate after nine months' treatment (all P<0.05). The predictive values of BRI and WHTR combined with pathological type were superior to other indicators [area under the curve (AUC)=0.716; AUC=0.714]. (3) Relation of obesity indicators and glucolipid indicators:BMI, WC, WHR, WHTR, BRI, LAP and VAI were positively correlated with homeostasis model assessment-insulin resistance index, glycosylated hemoglobin, and triacylglycerol (all P<0.05); while VAI was negatively correlated with high density lipoprotein cholesterol (P<0.001). Conclusions: For patients with EAH and EC treated with fertility preservation therapy, abnormal obesity indexes affect the treatment effect. BRI and WHTR combined pathology have good predictive value for effect of fertility preservation treatment. In clinical practice, appropriate indicators could be selected to evaluate body shape, glucolipid metabolism and predict efficacy.

Monkeypox is a rare infectious disease caused by the monkeypox virus, which used to occur endemically in central and western Africa. As of 25th May, a total of 219 recently confirmed cases of monkeypox have been reported from 19 non-endemic countries. This outbreak unusually takes place in non-endemic areas for monkeypox virus and has exhibited features of high risk of human-to-human transmission. Onset of multiple human monkeypox cases may be related to the decreased level of herd cross-immunity after the cessation of smallpox vaccination. Moreover, behavioral patterns in specific populations may account for the human-to-human transmission in this outbreak. Currently, possibility of global epidemic of monkeypox is extremely low, but China should be cautious about risks of importation of monkeypox cases. The key to prevention and control is to establish a surveillance system to identify suspicious cases and close contacts as soon as possible.

Objective: To evaluate the improvement of papilledema and visual acuities in patients with idiopathic intracranial hypertension (IIH) after venous sinus stenting. Methods: The clinical data of 8 IIH patients who met the inclusion criteria underwent venous sinus stenting between January 2013 and December 2016 at Department of Neurosurgery, Tianjin Huanhu Hospital were analyzed retrospectively. There were 6 females and 3 males,aged (32.9±14.4)years (range:19 to 57 years).The thickness of the retinal nerve fiber layer (RNFL) was measured by optical coherence tomography. Fundus,visual acuity and visual field examination were performed before and after operation. If pressure gradient ≥10 mmHg(1 mmHg=0.133 kPa) across the venous stenosis was indicated by intraoperative pressure measurement,the patient would be treated with venous sinus stenting. Intracranial pressure was measured by lumbar puncture 3 to 7 days after operation. RNFL thickness and eye examination were detected 6 months after surgery. CT venogram was used to observe the sinus venous conditions. Paired t test was used to compare the data before and after surgery. Results: All the 8 patients underwent venous sinus stenting successfully. The mean pressure gradient across the venous stenosis was reduced from (24±9.2) mmHg to (2.6±2.0) mmHg (t=8.02,P<0.01). Intracranial pressure decreased from preoperative (41.4±12.7) cmH2O(1 cmH2O=0.098 kPa) to postoperative (12.9±3.3) cmH2O (t=7.08, P<0.01). The RNFL thickness decreased from (275.3±68.3)µm to (131.4±31.8)µm(t=5.80,P<0.05) 6 months after surgery and the baseline visual acuity was improved from(M(QR))0.24 (0.25) to 0.65 (0.23)(Z=-2.52,P<0.05).Papilledema was significantly improved in 6 patients,and no significant change in 2 patients. CT venogram indicated adjacent stent restenosis in 1 patient. Conclusion: Venous sinus stenting can effectively improve papilledema and visual acuity caused by IIH.

Objective: To investigate the clinical diagnosis and treatment of congenital laryngotracheoesophageal cleft (LTEC) in children. Methods: The clinical data of 8 children (including 7 males and 1 female)with congenital laryngotracheoesophageal cleft from January 2016 to June 2020 were retrospectively analyzed. The median diagnosing age was 3.75 months (5 days to 12 months). According to the modified Benjamin Inglis classification proposed by Sandu in 2006,there were 3 cases of type â ¡, 3 cases of type â ¢a, 1 case of type â ¢b and 1 case of type â £a. All children were followed up regularly. Results: Six patients were treated for recurrent bronchopneumonia and aspiration during feeding. The patients were first treated in the pneumology departmentt or intensive care unit. Six patients combined with other malformations. Endoscopic repair operations were performed in 6 cases (3 cases of type â ¡, 3 cases of type â ¢ a), 1 case of LTEC was operated through cervical approach, and 1 case of type IVa LTEC associated with VACTERL was repaired under thoracoscope combined with suspension laryngoscope. Seven patients underwent tracheotomy before or during the repair operations. Gastrostomy was performed in 2 children. The operations were successfully performed in all cases. Three children with type â ¡ LTEC recovered well and decannulated. One case of type â ¢a was followed up for 5 months with occasionally choking while feeding. Two cases of type â ¢a, 1 case of type â ¢b and 1 case of type â £a died due to severe reflux, tracheomalacia or respiratory failure. Conclusions: Congenital LTEC is a rare congenital malformation which is difficult to diagnose for the poor specificity of clinical manifestations. LTEC needs to be classified by endoscopy examination under general anesthesia. Severe cases of LTEC have poorer outcomes than the mild cases, and the perioperative managements need multi-disciplinary cooperation to reduce the mortality.

Objective: To explore the noise exposure level and the health status of workers in transportation equipment manufacturing industry, and provide a scientific basis for guidance and implementation of intervention measures. Methods: From January to December in 2019, a total of 2088 noise workers from a large enterprise were selected by cluster sampling method in railway transportation equipment manufacturing, automobile manufacturing and aerospace aircraft manufacturing enterprises. The worker's noise exposure level was detected. Occupational health checkups were performed on the noise workers including electrical audiometry, blood pressure and electrocardiogram. χ(2) test and trend χ(2) test were used to analyze the data. Results: The noise exposure level of 66.9% (1396/2088) workers exceeded 85 dB (A) , and the median noise level was 87.9 (84.3-90.3) dB (A) . Among them, workers of railway transportation equipment manufacturing enterprises had the highest noise exposure level[89.9 (87.8-91.6) dB (A) ]. The detection rate of high-frequency hearing loss, abnormal blood pressure and abnormal electrocardiogram of noise workers were 15.7% (327/2088) , 18.1% (378/2088) and 6.1% (128/2088) , respectively. The differences in the detection rates of high-frequency hearing loss, abnormal blood pressure, and abnormal electrocardiogram in workers of railway transportation equipment manufacturing enterprises, automobile manufacturing enterprises, and aerospace manufacturing enterprises were statistically significant (P<0.05) . Workers of railway transportation equipment manufacturing enterprises had higher detection rates of high-frequency hearing loss (17.6%, 186/1056) . Workers of aerospace manufacturing enterprises had higher detection rates of abnormal blood pressure and abnormal electrocardiogram (26.3%, 169/642; 10.0%, 64/642) . The differences in the detection rates of high-frequency hearing loss, abnormal blood pressure and abnormal electrocardiogram of noise workers were statistically significant in different age and working age groups, and gradually increased with age and working age (P<0.05) . The difference in the detection rate of high-frequency hearing loss of noise workers was statistically significant in different noise intensity groups, and the overall trend was increasing (P<0.05) . Conclusion: The transportation equipment manufacturing industry has serious noise hazards, especially the railway transportation equipment manufacturing industry. Long-term occupational noise exposure can adversely affect workers' hearing and cardiovascular system. Enterprises should strengthen occupational health inspections, and at the same time, take personal protective measures to protect the health of workers.

Objective: To discuss the complications and postoperative outcomes of tracheotomy with different etiology in children. Methods: One hundred and eighty-six patients underwent tracheotomy were retrospectively analyzed from January 2016 to December 2018,including 117 males and 69 females. The children aged from 4 days to 14 years (median age 31.5months). One case was operated under local anesthesia in emergency room, 2 cases were operated under local anesthesia in pediatric intensive care unit, the rest 183 cases were operated under general anesthesia in operation room. The 186 children were divided into four groups according to their direct causes of tracheotomy. Group A(90 cases): Neuromuscular disease and severe infection,Group B(26 cases): Head and neck tumor,Group C(57 cases): Congenital malformation and upper airway obstruction,Group D(13 cases): Accidental injury. The basic information, surgical complications and postoperative outcomes were recorded and analyzed. All patients were followed up by clinic or by telephone. Spss 19.0 software was used for statistical analysis. Results: One hundred and eighty-six patients were followed up for one to four years. 33 children lost the follow-up and 46 died. Among the 186 patients, 23 cases had emergency tracheotomy (12.4%). The rate of emergency tracheotomy in group C(16 cases, 28.1%) was higher than that in the other three groups(χ2=28.08,P<0.05). The average age of patients and hospital stay in group C were significantly lower than those in the other three groups (F=33.76,P<0.05; F=14.95,P<0.05). Incision bleeding occurred in 11 cases, Subcutaneous emphysema occurred in 6 cases and accidental decannulation occurred in 10 cases (4 cases within 2 weeks and 6 after 2 weeks). Six patients underwent tracheocutaneous fistula closure operation after decannulation and the stoma healed spontaneously in other extubated children. Two patients underwent secondary tracheotomy due to accidental decannulation, and three patients underwent secondary tracheotomy for dyspnea after decannulation. In 107 cases of survival children, decannulation was successful in 65 patients and failed in 42 patients. The average duration of wearing tracheal tube was 8.8 months. The decannulation rates in the four groups were 55.6%, 45%, 69% and 77.8%, with no significant difference. Conclusions: The complications after tracheotomy in children are rare, and no severe complications occurred in long-term tracheotomy patients. The duration of wearing tracheal tube is related to the treatment of their primary disease.

OBJECTIVE: The incidence of thyroid cancer is rising globally. Most patients progress slowly, but some patients develop lymph node and distant metastasis earlier, and their prognosis is poor. Therefore, early diagnosis and warning of malignancy are very meaningful for such patients. SAS1B gene is a newly discovered protein expressed on the surface of mature egg cells and has metalloendopeptidase activity. We aimed at exploring whether SAS1B is involved in the occurrence of thyroid cancer, and at providing evidence for early diagnosis and targeted therapy of thyroid cancer. PATIENTS AND METHODS: In this study, a rabbit anti-human SAS1B polyclonal antibody was prepared by gene recombination technology. The indirect ELISA method was used to detect the SAS1B protein expression in the serum of 69 patients with thyroid cancer and 55 normal controls, and the relevant pathological factors were analyzed. Immunohistochemistry and PCR technology were used to investigate the expression levels of SAS1B protein and mRNA in 30 thyroid cancer tissues and 23 control thyroid tissues. RESULTS: The titer of SAS1B recombinant antibody was 1:51200. The expression of SAS1B in the serum of patients with thyroid cancer was higher than that in the normal control group (p<0.01). The antibody had a good sensitivity in serum detection of cancer patients (p=0.008<0.01), the linear regression analysis result was that the expression of SAS1B gene was related to tumor envelope invasion and lymph node metastasis (p=0.003<0.01, p=0.003<0.01), and it was irrelevant to the patient's gender, age, tumor mass size, number of cancer foci, pathological stage, etc. (p>0.05). The results of immunohistochemistry showed that SAS1B protein was mainly located in the cytoplasm and membrane of thyroid cancer cells. The expression intensity in thyroid cancer tissues was higher than that in control tissues (p<0.05), but it was not expressed in normal thyroid tissues. Antibodies showed a good sensitivity that was used to detect thyroid cancer tissues (p=0.000<0.01). The results of ordinary PCR detection using thyroid cancer tissue and control thyroid tissue showed that the amplification products of the three domains (N-terminal, C-terminal and catalytic domain) of the SAS1B gene showed high expression in thyroid cancer tissue. q-PCR results showed that the expression of SAS1B gene in thyroid cancer and control thyroid tissue was higher than that in control group (p<0.05), and the genes of Aurora A and BARD1 related to centrosome replication and DNA replication forks protection during the proliferation were highly expressed in thyroid cancer tissue. The study results suggested that SAS1B was involved in the carcinogenesis of thyroid cancer. The Hum_mPLoc.2.0 software, PSORT â ¡ software and UniProt software were used to predict that SAS1B protein had secretory protein properties. CONCLUSIONS: The above data indicate that the SAS1B gene is closely related to the process of thyroid cancer and can serve as a good tumor marker that can be used for early diagnosis and early warning of thyroid malignancy.
