ABSTRACT

Abstract Introduction Ultrasound sonography provides a quick method for determining which nodule to sample for fine needle aspiration biopsy in thyroid nodules. On the other hand, the computed tomography examination is not restricted by echo attenuation and distinguishes between benign and malignant nodules. Objective To compare computed tomography examinations against ultrasound/fine needle aspiration biopsy in the differential diagnosis of thyroid nodules. Methods Data regarding computed tomography examinations, sonographic finding following fine needle aspiration biopsy, and tumor histology of 953 nodules from 698 patients who underwent thyroidectomy were collected and analyzed. The beneficial score for detection of the malignant tumor for each adopted modality was evaluated. Results Ultrasound images did not show a well-circumscribed solid mass in 89 nodules, and ultimately did not detect nodules in fine needle aspiration biopsies (false positive non-malignant nodules). Ultrasound images showed parenchymatous disease (false positive malignant nodules) in several nodules. Computed tomography examinations demonstrated higher difficulty in detection of malignant nodules of 1.0-2.0 cm size than ultrasound examination following fine needle aspiration biopsies; compared to tumor histological data, computed tomography examinations had a sensitivity of 0.879. Conclusion Computed tomography examinations are a more reliable method for differential diagnosis of thyroid nodules than ultrasound examinations followed by fine needle aspiration biopsy. Level of Evidence III.


Resumo Introdução A ultrassonografia é um método rápido para determinar de qual nódulo se deve coletar uma amostra para biópsia por aspiração com agulha fina. Por outro lado, o exame de tomografia computadorizada não é restringido pela atenuação do eco e distingue entre nódulos benignos e malignos. Objetivo Comparar exames tomográficos versus biópsia por ultrassonografia/aspiração por agulha fina no diagnóstico diferencial de nódulos tireoidianos. Método Dados sobre exames tomográficos, achados ultrassonográficos após biópsia por aspiração com agulha fina e histologia tumoral de 953 nódulos de 698 pacientes submetidos à tireoidectomia foram coletados e analisados. O escore de benefício para detecção do tumor maligno para cada modalidade adotada foi avaliado. Resultados As imagens de ultrassom não mostraram uma lesão sólida bem circunscrita em 89 nódulos; e na análise final não foram detectados nódulos nas biópsias por aspiração com agulha fina (nódulos não malignos falsos positivos). As imagens ultrassonográficas mostraram doença parenquimatosa (nódulos malignos falsos positivos) em vários nódulos. Os exames de tomografia computadorizada apresentaram grandes dificuldades na detecção de nódulos malignos de 1,0-2,0 cm de tamanho em comparação com o exame de ultrassonografia após biópsias por aspiração com agulha fina; comparados aos dados histológicos do tumor, os exames de tomografia computadorizada apresentaram sensibilidade de 0,879. Conclusão Os exames de tomografia computadorizada são um método mais confiável para o diagnóstico diferencial de nódulos tireoidianos do que os exames de ultrassonografia, seguidos por biópsia por aspiração com agulha fina.

ABSTRACT

Chrysanthemi Indici Flos(CIF), the capitulum of Chrysanthemum indicum, is widely used in proprietary Chinese medicine and daily chemical products. At present, CIF is mainly produced from wild resources and rarely cultivated. This study aims to reveal the correlations between linarin content in CIF and climatic factors in different habitats, and provide a theoretical basis for suitable zoning and rational production of medicinal materials. The content of linarin in CIF was determined by HPLC. Grey relational analysis and Pearson correlation analysis were carried out for linarin content with climatic factors. The results showed that the content of linarin in CIF was significantly different among different habitats. The grey relational degrees of climatic factors with linarin content was in an order of average annual precipitation>annual average sunshine hours>annual average temperature>longitude>annual frost-free period>latitude>altitude. Longitude, annual average temperature and average annual precipitation had significantly positive correlations with the content of linarin in CIF, whereas latitude and altitude showed negative correlations with it. The annual frost-free period and annual average sunshine hours had no significant correlation with the content of linarin in CIF. The content of linarin in CIF varied significantly in different habitats. High longitude, low latitude, low altitude, high annual average temperature and high annual average precipitation could be used as indicators for the habitats of high-quality Ch. indicum. This study provides a reference for selecting suitable producing areas of Ch. indicum and establishing artificial cultivation system.

ABSTRACT

The study is aiming at investigating the application of entropy weight TOPSIS method in the comparison of the scavenging effect of DPPH, ABTS and hydroxyl radical and the inhibition effect of xanthine oxidase(XOD) and lipoxygenase(LOX) of Chrysanthemum indicum. The DPPH, ABTS, salicylic acid and spectrophotometry were used to determine the scavenging effect of DPPH, ABTS and hydroxyl radical and the inhibition effect of xanthine oxidase(XOD) and lipoxygenase(LOX) of Ch. indicum from 31 different areas in vitro. Take the half inhibition rate of as the evaluation index, two principal components were extracted by the principal component analysis, and their cumulative contribution rate reached at 92.4%. The different areas of Ch. indicum could be divided into Dabei Mountain and Qinling-Taihang Mountain by use principal component to analysis. The entropy weight TOPSIS method was used to objectively assign weights to five indexes, calculate the weight of each index and set up the best and worst scheme of the evaluation object, and the relative proximity(C_i) was used as the measure to construct the multi-index comprehensive evaluation model of Ch. indicum. And then sort with the relative proximity value. The results showed that the relative proximity was between 0.098 and 0.983 which represents there were significant differences in the scavenging effect of DPPH, ABTS and hydroxyl radical and the inhibition effect of xanthine oxidase(XOD) and lipoxygenase(LOX) between extracts of Ch. indicum from different areas. The Ch. indicum from Dabie Mountain area have a relatively high relative degree of measurement and high-quality ranking. Taken together, the quality of Ch. indicum.from the Dabie Mountain area is better. The index weight coefficient and the classification result of producing area are basically consistent with the result of principal component analysis. The results show that the TOPSIS method based on entropy weight method can be used to evaluate the comprehensive quality of Ch. indicum.

ABSTRACT

Chinese medicinal material is the foundation of traditional Chinese medicine(TCM) industry. Its quality is not only closely related to the health of residents but also the key to the development of the TCM industry. Pesticide residues, heavy metals and mycotoxins are the major pollutants of Chinese medicinal materials. In recent years, quite a number of rapid detection methods for pollutants have been constructed. Among them, surface-enhanced Raman scattering(SERS), which has been widely used in food chemistry, environmental analysis, and other fields because of its speediness and non-destructiveness, shows its great potential in the pollutant detection in Chinese medicinal material. This paper firstly reviews the application of SERS for the detection of common pollutants in Chinese medicinal material. We then discussed the characteristics and advantages of SERS technique for pesticide detection, including the principle, SERS substrate design, specific recognition, etc. Finally, simultaneous detection of multiple pesticide residues in Chinese medicinal material was explored.

ABSTRACT

Drug-induced liver injury and herbal preparations containing pyrrolizidine alkaloid (PA) have gained global attention. The purpose of this research was to investigate the effects and mechanisms of Alismatis Rhizoma, a traditional Chinese medicine, to protect against acute liver injury in mice induced by senecionine (SEN), a representative toxic PA compound. All experiments were approved by the Animal Research Committee of Shanghai University of Traditional Chinese Medicine. Animal welfare and the animal experimental protocols were strictly consistent with related ethics regulations of Shanghai University of Traditional Chinese Medicine. Acute liver injury was induced by a single intragastric administration of SEN (50 mg·kg-1). Mice in the protection groups received intragastric administration of Alismatis Rhizoma water extract (WE, 18 g·kg-1 per day) or ethanol extract (EE, 18 g·kg-1 per day) 5 days before SEN treatment. The results show that Alismatis Rhizoma extracts can significantly attenuate acute liver injury in mice. Mice in the protection groups showed decreased serum activities of alanine aminotransferase and aspartate aminotransferase, as well as decreased total bile acids. In addition, the infiltration of inflammatory cells, sinusoidal hemorrhage, and hepatic necrosis in SEN-treatment mice was clearly attenuated in the protection groups. Interestingly, EE showed a better effect than WE. The content of principal bile acids in serum and the mRNA and protein expression of key factors related to bile acid metabolism were also measured. Alismatis Rhizoma up-regulated the bile acid transporters and drug metabolism enzymes, consistent with the observed bile acid homeostasis and alleviation of SEN-induced injury to hepatocytes. The present study points to the possibility of utilizing Alismatis Rhizoma for protection against liver injury caused by drugs and preparations containing PA.

ABSTRACT

OBJECTIVE:To stud y the effects of sinapine thiocyanate (ST) on the proliferation ,epithelial mesenchymal transformation(EMT)and metastasis of human cutaneous squamous cell carcinoma SCL- 1 cells,and to investigate its possible mechanism. METHODS :Human cutaneous squamous cell carcinoma SCL- 1 cells were divided into blank control group (0.1% DMSO) and ST different concentration groups (5,10,20 μmol/L). CCK- 8 assay,5-ethynyl-2′-deoxyuridine(EDU)test, scratch test and Transwell chamber invasion test were adopted to test the proliferation ,migration and invasion ability. The expression of N-cadherin and E-cadherin were detected by Western blot and immunofluorescence assay . Other SCL- 1 cells were collected and divided into blank control group (0.1% DMSO),ST group (20 μmol/L),ST+NSC228155 group [ 20 μmol/L ST+100 μmol/L NSC228155(EGFR agonist )] and ST+SC 79 group [ 20 μmol/L ST+20 μmol/L SC79(PI3K/Akt agonist )]. The proliferation ,migration and invasion ability of SCL- 1 cells in each group were detected by CCK- 8 assay,scratch test and Transwell chamber invasion assay. The expression of epidermal growth factor receptor (EGFR),phosphatidylinositol 3 kinase(PI3K),phosphorylated phosphatidylinositol 3 kinase(p-PI3k),protein kinase B (Akt)and phosphorylated protein Akt (p-Akt)protein of cells in blank control group and ST different concentration groups(5,10,20 μmol/L)were determined by Western blot assay so as to validate the relationship between ST effect and EGFR/ PI3K/Akt signaling pathway. SCL- 1 cells and human normal skin fibroblasts cell WS 1 were divided into blank control group (0.1% DMSO),ST group (20 μmol//L),ZD1839 group(positive control ,20 μmol//L,EGFR inhibitor )and LY 294002 group(positive control,20 μmol//L,PI3K/Akt inhibitor ). CCK- 8 assay was used to detect the cell proliferation in order to evaluate the cells cytotoxicity of ST. RESULTS :Compared with blank control group ,the proliferation ,migration and invasion ability of SCL- 1 cells were significantly decreased in 5,10,20 μmol/L ST groups(P<0.05). Western blot and immunofluorescence assay showed that the expression of N-cadherin in SCL- 1 cells were decreased significantly in 5,10,20 μmol/L ST groups(P<0.05),while the protein expression of E-cadherin was increased significantly (P<0.05);the protein expressions of EGFR ,p-PI3K and p-Akt were significantly decreased (P<0.05). Compared with ST group ,the proliferation ,migration and invasion ability of SCL- 1 cells were increased significantly in ST + NSC 228155 group and ST + SC 79 group (P<0.05). Compared with blank control group ,the proliferation ability of WS 1 cells had no significant change in ST group ,while the proliferation ability of SCL- 1 cells was decreased significantly (P<0.05);the proliferation ability of the two kinds of cells were decreased significantly in ZD 1839 group and LY 294002 group(P<0.05). Compared with ST group ,the proliferation ability of WS 1 cells was decreased significantly in ZD1839 group and LY 294002 group(P<0.05),but there was no significant difference in the proliferation ability of SCL- 1 cells (P>0.05). CONCLUSIONS :ST may inhibit the proliferation ,EMT and metastasis of SCL- 1 cells through inhibiting the activation of EGFR/PI 3K/Akt signaling pathway ,and its side effects are few.

ABSTRACT

This study aims to investigate the effect of baicalein on the metastasis of esophageal squamous cell carcinoma (ESCC) cells, and to elucidate the potential molecular mechanisms. Wound healing and Transwell migration and invasion assays were performed to detect the effect of baicalein on the migration and invasion of EC9706 and KYSE30 cells; the nude mice models of lung metastasis were applied to examine the function of baicalein in metastasis of ESCC by using KYSE30 cells. All animals were received humane care according to the Institutional Animal Care Guidelines approved by the Experimental Animal Ethical Committee of Henan University. Western blot assay was used to detect the protein levels of ERK/ELK-1/Snail signaling pathway. The data showed that baicalein significantly inhibited the migration and invasion of EC9706 and KYSE30 cells; Mechanistically, baicalein treatment led to a dramatically reduced expression of phosphorylated extracellular signal-regulated kinase 1/2 (p-ERK1/2, T202/Y204), p-ETS-domain containing protein-1 (p-ELK-1, S383), Snail, N-cadherin, and Vimentin, and a statistical increase of E-cadherin expression in EC9706 and KYSE30 cells; Furthermore, the inhibition of ERK1/2 by U0126 or siRNA remarkably enhanced the effect of baicalein on the above proteins. In summary, baicalein probably inhibits the migration, invasion, and metastasis of ESCC cells via blocking the ERK/ELK-1/Snail signaling pathway.

ABSTRACT

Nanomedicine has great potential in cancer therapy, but the complex tumor microenvironment greatly prevents nanomedicine from being effectively delivered into tumor in vivo. It has been widely accepted that the encapsulated drugs in the nanoparticles have to go through five major cascading steps, including blood circulation, accumulation in tumor, penetration into the depth of tumor tissue, internalization by tumor cells and then intracellular drug release, before they can exert the anti-tumor efficacy. Among the five steps, drug accumulation in tumor and penetration in the depth of tumor have been the two major issues undermines the antitumor efficacy of nanomedicine. This paper summarizes the new major progress in improving the tumor accumulation and penetration of nanomedicine, especially the technologies that appeared or developed in the last five years.

ABSTRACT

Objective:To evaluatte the high risk factors of stent occlusion in patients with acute iliofemoral vein thrombosis and Cockett syndrome.Methods:The clinical data of 178 patients of Cockett syndrome and acute lower extremity deep vein thrombosis from Jan 2014 to Dec 2016 was analyzed retrospectively. All patients underwent catheter directed thrombolysis or percutaneous mechanical thrombectomy combined with stent placement. The patency rate of stent was followed up by color Doppler ultrasound. Patients were divided into study group (stent occlusion) and control group (stent patency).Results:The stent patency rate at 6 months was 83.7%, body mass index ( OR=1.245, 95% CI: 1.097-1.413), time of thrombosis more than 2 weeks ( OR=3.899, 95% CI: 1.147-13.257), low thrombus clearance ( OR=0.238, 95% CI: 0.117-0.486) was the high risk factor of short-term stent occlusion. Stent patency rate at 3 years was 75.3%, body mass index( OR=1.225, 95% CI: 1.076-1.394), thrombosis history more than 2 weeks( OR=11.777, 95% CI: 2.576-53.832), malignant tumor( OR=4.444, 95% CI: 1.153-17.127) , compression therapy( OR=0.332, 95% CI: 0.113-0.977), low thrombus clearance( OR=0.184, 95% CI: 0.089-0.381), long stents( OR=8.427, 95% CI: 2.329-30.488) was the high risk factor for mid-term stent occlusion. Conclusions:Obesity, the duration of thrombus longer than 2 weeks and low thrombus clearance are the high risk factors of early stent occlusion, while malignant tumor, irregular compression therapy and long stents may lead to lower medium and long term patency rate of the stent.

ABSTRACT

In recent years, with the development of sequencing technology and research on molecular changes in different races of prostate cancer, it has been found that the pathogenesis of prostate cancer showed obvious ethnic differences. This article reviewed the research progress of ETS fusion genes, FOXA1, SPOP, IDH1 and other driver genes in prostate cancer. And the research of molecular typing of prostate cancer showed different patterns of molecular changes in Chinese and western populations. The molecular changes of prostate cancer in western populations were dominated by ETS fusion gene, while those in Chinese populations were dominated by gene mutations, mainly FOXA1 and SPOP mutations. Moreover, the dominant fusion gene in Chinese prostate cancer was not ETS fusion gene, but SCHLAP1-UBE2E3.

ABSTRACT

Objective:To investigate the factors related to recurrence and prognosis of retroperitoneal liposarcoma.Method:The clinical data of patients with primary retroperitoneal liposarcoma who underwent surgical treatment in the First Affiliated Hospital of Zhengzhou University from June 2011 to January 2020 were analyzed retrospectively. There were 42 males and 47 females and patients’median age was 53 (26-78). Sixty-five cases were treated by operation in our hospital, and 24 cases were primarily treated by the operation in another hospital. The clinical manifestations of the initial diagnosis included retroperitoneal mass in 41 cases, abdominal distension in 12 cases, abdominal pain in 10 cases, fever in 11 cases, nausea, vomiting and poor appetite in 8 cases, frequent urination and dysuria in 6 cases, and bilateral lower limb edema in 1 case. Preoperative CT imaging showed that the tumor body was located in the retroperitoneal kidney area in 58 cases, while in the retroperitoneal space or the pelvic extraperitoneal space in 31 cases. There were 55 single cases and 34 multiple cases. The median tumor length was 20(3-52) cm. Among the primarily treated 65 patients, 47(72.3%) were considered as primary retroperitoneal liposarcoma by preoperative imaging examination. Among the 89 patients treated by surgery, 78 underwent endoscopic surgery, among which 21 underwent laparoscopic surgery, 38 cases of retroperitoneal laparoscopic surgery, 19 cases of Da Vinci robot-assisted laparoscopic surgery. Open operation was performed in 11 cases. There were 87 patients undergoing radical resection and 2 patients undergoing palliative resection. Forty-two patients underwent intraoperative combined resection of the adjacent organs. The recurrence and survival status of patients were followed up.Results:All the 89 patients underwent the operation successfully, with the median operative blood loss of 200 (10-2000) ml. There were 23 cases being diagnosed of well differentiated liposarcoma, 40 cases of dedifferentiated, 20 cases of myxoid/round, 5 cases of myxoid liposarcoma, and 1 cases of mixed type. Pathologically, there 42 cases with low grade histology and 47 cases with high grade histology. In this study, 89 patients were followed up for 3 to 108 months, and the median follow-up time was 28 months. The 5-year recurrence free survival rate, disease-free survival rate and overall survival rate of the patients were 16.7%, 16.1% and 52.6%, respectively. There were 57 patients presenting local recurrence, 1 patient of lung metastasis, and 1 patient of liver metastasis, and the median disease-free survival time was 24 months. There were 42 patients died of the disease, with a median survival time of 64 months. Univariate analysis showed that intraoperative blood loss( P<0.01), whether multiple cases( P<0.01), pathologic types( P<0.01), and histological grades ( P<0.01) were related to disease-free survival.The intraoperative blood loss( P<0.01), multiple cases( P<0.05), pathologic types ( P<0.05), and recurrence ( P<0.01)were related with overall survival. Gender, age, tumor size, tumor location, whether primary surgery, radical resection or combined resection of adjacent organ had no effect on the prognosis of patients ( P>0.05). Cox regression model multivariate analysis revealed that surgical bleeding ( RR=2.360, 95% CI 1.313-4.241, P=0.004), multiple tumor ( RR=1.899, 95% CI 1.068-3.375, P=0.029), and pathological type ( RR=4.976, 95% CI 1.622-15.264, P=0.005) were independent factors affecting disease-free survival. The recurrence was an independent factor affecting the overall survival of patients ( RR=31.495, 95% CI 1.062-933.684, P=0.046). Conclusions:Retroperitoneal liposarcoma is a rare disease with high recurrence rate. The intraoperative blood loss, whether multiplicity and pathological type are independent factors affecting the disease-free survival, and recurrence is independent factors affecting the overall survival.

ABSTRACT

Objective:To explore the clinical features and prognosis of urachal carcinoma.Methods:The clinical data of 35 patients with urachal carcinoma admitted to the First Affiliated Hospital of Zhengzhou University from August 2011 to November 2019 were analyzed retrospectively. There were 23 males and 12 females, with a male to female ratio of 1.92∶1. The average age was (52.1±13.9) years old, and the median age was 55 years old. There were 8 patients with a history of smoking and 3 patients with a history of drinking. There were 5 cases of hypertension, 5 cases of diabetes, 2 cases of coronary heart disease, and 1 case of cerebral infarction. The first symptoms were hematuria in 25 cases, lower abdominal pain in 4 cases, abdominal mass in 2 cases, umbilical discharge in 1 case, and asymptomatic in 4 cases.Preoperative CT examination showed that the tumor was located on the top wall of the bladder in 24 cases and the front wall of the bladder in 11 cases. There were 25 solid tumors and 10 cystic tumors. The maximum diameter of the tumor was 1.5 to 11.0 cm, and the median maximum diameter of the tumor was 4.0 cm. Preoperative cystoscopy detected masses on the anterior or top wall of the bladder and urachal carcinoma was suspected in 35 cases. All 35 cases underwent enlarged partial cystectomy (conventional resection of the umbilical part), and 3 cases underwent pelvic lymph node dissection at the same time. Among them, 19 cases underwent open surgery, 14 cases underwent laparoscopic surgery, and 2 cases underwent Da Vinci robot assisted laparoscopic surgery.Results:According to Mayo staging, there were 10 cases of stage Ⅰ, 18 cases of stage Ⅱ, 1 case of stage Ⅲ, and 6 cases of stage Ⅳ. The overall follow-up rate was 91.4% (32/35), and the median follow-up time was 41 (3-103) months. The 1-year survival rate was 82.5%, the 3-year survival rate was 59.3%, and the 5-year survival rate was 53.9%. Univariate analysis showed that age ( P=0.033), maximum tumor diameter ( P=0.011), lymph node metastasis ( P=0.002), distant metastasis ( P=0.011), pathological grade ( P=0.001), Mayo staging ( P=0.026) were ralated prognostic factors (all P<0.05). Cox multivariate analysis showed that the pathologically poor differentiation ( HR=1.640, 95% CI 1.112-2.418, P=0.013), and the largest tumor diameter ≥4cm were ( HR=5.000, 95% CI 1.099-22.755, P=0.037). Independent factors affecting patient prognosis. Conclusions:Urachal carcinoma is a malignant bladder tumor with insidient onset. Most of the first diagnosis symptoms are hematuria. When diagnosed, most patients are in the middle and late stages of clinical grading, and the prognosis is poor.Pathological grade and maximum tumor diameter are independent factors that affect the prognosis of patients with urachal carcinoma. The higher was the pathological grade, and the larger was the maximum tumor diameter, the worse was the prognosis.

ABSTRACT

Objective:To implement an intervention with community-dwelling middle-aged and elderly people through a new science promotion approach, and to evaluate changes in the level of bone health awareness.Methods:From April 2017 to June 2017, 200 community-dwelling middle-aged and elderly people aged 50 years and over were randomly included.They were divided into the intervention group receiving a new science promotion intervention(n=100, with 50 males and 50 females)and the control group(n=100, with 50 males and 50 females). Baseline and follow-up assessments of bone health awareness were performed before and after the one-year intervention.A questionnaire survey on preferences for different types of science promotion articles in WeChat accounts was conducted.Differences in scores for intervention effects before and after intervention were compared between the two groups.Potential influencing factors for the scale score were examined by a multi-factor analysis.Results:After one year of intervention, scores for intervention effects were higher in the intervention group than in the control group( P<0.001). In the intervention group, scores were higher after intervention than before intervention( P<0.001). In the control group, scores after follow-up were slightly higher than those at baseline(29.4±11.4 vs.27.9±10.1, P<0.001). The increase in scores before and after intervention was greater in the intervention group than in the control group( P<0.001). Baseline score, group designation, history of drinking and diabetes impacted the scores in middle-aged and elderly women, while other factors did not.Most middle-aged and older people preferred texts illustrated with pictures, and older people were more receptive to videos. Conclusions:The new science promotion method is beneficial to bone health management, can improve bone health awareness in middle-aged and elderly people.

Objective:To investigate the feasibility and clinical effects of thoracic endoscopic-assisted anterior-lateral decompression and fusion for thoracolumbar or upper lumbar disc herniation (LDH) associated with vertebral osteochondrosis (VO).Methods:From December 2017 to December 2019, 10 patients of thoracolumbar or upper LDH associated with VO were treated with thoracic endoscopic-assisted anterior-lateral decompression and fusion, including 6 men and 4 women, with an average 49.2 years old (range, 37 to 65 years old). The involved levels included T 12L 1 in 5 cases, L 1, 2 in 2 cases and L 2, 3 in 3 cases. There were 4 cases of simple thoracolumbar or upper LDH associated with VO and 6 cases of thoracolumbar or upper LDH associated with VO combined with ligamentum flavum hyperplasia and ossification or kyphosis (combined with posterior decompression and internal fixation or posterior correction surgery). The visual analogue scale (VAS), Oswestry disability index (ODI) and anterior and posterior height of intervertebral space were evaluated at follow-up. The clinical effects were evaluated according to the modified MacNab criteria. Results:The operation was performed successfully in all the patients. During the operation, the herniated disc and ossification were clearly exposed and completely removed, with the sufficient decompression of spinal cord, nerve root and dural sac. The operation duration was 115.4±23.8 minutes (range, 70 to 180 mins). Intraoperative bleed loss was 122.6±21.3 ml (range, 40 to 310 ml). The patients were followed up for averagely 21.6 months (range, 12 to 36 months). At the final follow-up, VAS score decreased from preoperative 7.2±1.9 to 1.8±1.1, and ODI decreased from preoperative 64.3%±13.9% to 16.3%±5.1% ( P<0.05). The anterior height of intervertebral space recovered from preoperative 7.8±1.5 mm to 11.9±2.3 mm, and the posterior height of intervertebral space recovered from preoperative 4.5±1.1 mm to 7.4±1.6 mm ( P<0.05). According to modified MacNab criteria, the results were excellent in 9 cases and good in 1 case. Conclusion:For thoracolumbar or upper LDH associated with VO, thoracic endoscopic-assisted anterior-lateral decompression and fusion provided clear vision of the surgical field, fully exposed and completely removed the herniated disc and ossification, which achieved satisfactory short-term results.

ABSTRACT

Objective:To evaluate the assistant role of manifestations under tracheoscopy in the diagnosis of invasive pulmonary aspergillosis (IPA) in severe patients.Methods:A retrospective study was conducted. The patients with suspected IPA admitted to intensive care unit (ICU) of Affiliated Hospital of Binzhou Medical College from January 2015 to December 2019 were enrolled. The diagnosis, clinical diagnosis and suspected diagnosis were made according to the grading criteria of Guidelines for the diagnosis and treatment of invasive fungal infection in severe patients (2007). Those who met the criteria were enrolled in the IPA group, and those who did not meet the criteria or other pathogens were enrolled in the non-IPA group. The general data of the patients were collected, and the changes of tracheal and bronchial mucosa under tracheal microscope before and after treatment were recorded, as well as the results of galactomannan (GM) test and aetiology culture of bronchoalveolar lavage fluid (BALF). The baseline, bronchoscopy and pulmonary CT manifestations and their dynamic changes were compared in each group. Results:A total of 142 patients with suspected IPA were finally enrolled. Among them, 12 were pathologically proven IPA, 77 were probable IPA, 22 were possible IPA, and 31 were undefined IPA. Of the 142 patients, 60 had typical manifestations of mucosal injury under bronchoscopy, including 7 proven IPA patients (58.3%), 52 probable IPA patients (67.5%), and 1 possible IPA patient (4.5%), but none undefined IPA patient. The patients undergoing lung CT scan were 12 proven IPA patients (100%), 73 probable IPA patients (94.8%), and 21 possible IPA patients (95.5%), respectively. Most of the Chest CT showed patchy or strip density increasing and other non-specific manifestations. There were 3 proven IPA patients (25.0%), 7 probable IPA patients (9.0%), and 0 possible IPA patient (0%) who had typical IPA CT manifestations (halo sign and cavity or crescent sign). Among the patients of proven IPA and probable IPA (89 cases), there were a total of 35 cases with endoscopic airway mucosal injury and tracheoscopy reexamination ≥ 3 times. All the 35 patients received anti-aspergillus treatment, among which 16 survived and 19 died. Among the 16 patients who survived, the microscopic appearance of mucosal injury was gradually reduced and the clinical manifestations were gradually improved. Of the 19 patients who died, 16 had deteriorated endoscopic airway mucosal injury.Conclusions:The specific manifestations of severe patients with bronchial mucosal injury are of great significance in the diagnosis of IPA. In the case of severe patients who cannot receive pathological examination or chest CT in time, dynamic observation of the changes of airway mucosal injury is a simple auxiliary method to discover the changes of patients' condition in time, evaluate the effect of antifungal therapy and the prognosis of IPA.

ABSTRACT

Objective:To provide clinical data for early identification and diagnosis of vascular embolism in children.Methods:We collected and analyzed the clinical data of children with vascular embolism diagnosed at the Children Medical Center of the First Affiliated Hospital of Hunan Normal University from January 2017 to January 2020.Results:A total of 29 children with vascular embolism were included.The male to female ratio was 2.2∶1(20/9); the age range was 1 month to 13 years, and the median age(IQR) was 16 (6-41)months.Among them, 22 cases were diagnosed with venous thrombosis, including 13 children with lower limb venous thrombosis(13/29, 44.8%), and six children with intracranial venous thrombosis(6/29, 20.7%). Arterial embolism was found in six cases, and left atrial appendage thrombosis was found in one case.Severe pneumonia was the most common primary disease(19/29, 65.5%), followed by cardiopulmonary resuscitation(3/29, 10.3%), and Kawasaki disease(3/29, 10.3%). Analysis on the risk factors of vascular embolization diseases, including catheter-related, long-term bed rest, elevated D-dimer, mechanical ventilation, and intravenous hormone administration, showed that 89.2%(25/29)had ≥3 risk factors at the same time, and 82.8%(24/29)had ≥5 risk factors at the same time.Conclusion:In children with vascular thrombotic diseases, deep venous thrombosis, especially lower extremity venous thrombosis, are common.The severe pneumonia is more common in primary disease.Children with multiple risk factors have a higher risk of developing vascular embolism.In clinic, coagulation function should be monitored and local symptoms should be observed for early identification.

ABSTRACT

Objective:To explore the effect of group painting art therapy on negative symptoms, the cognitive status and social function of patients with schizophrenia during rehabilitation.Methods:A total of 114 patients with schizophrenia recovered from May 2018 to May 2019 in Zhangjiakou Shalingzi Hospital. They were divided into two groups according to the random number table method with 57 case in each group, the control group was given routine nursing, and the observation group received group painting art therapy on the basis of routine nursing. The Positive And Negative Symptoms Scale (PANSS), MATRICS Consensus Cognitive Battery(MCCB), and Social Disability Screening Schedule (SDSS) were used to evaluate the symptoms, cognitive status, and social function improvement of the two groups before and after intervention.Results:There were no significant differences in the negative symptom scores and positive symptom scores of the PANSS between the two groups of patients before the intervention ( P>0.05). After the intervention, the scores of negative symptoms and general psychopathology were (11.83 ± 3.19), (17.30 ± 4.93) points in the observation group and (13.57 ± 2.85), (20.34 ± 5.12) points in the control group, the differences were significant ( t values were 2.789, 2.932, P<0.05). After the intervention, the 7-dimensional MCCB scores of the two groups of patients decreased, and the scores of the observation group were significantly lower than those of the control group ( t values were 2.046-3.238, P<0.05). After the intervention, the score of SDSS was (11.63±2.71) points in the observation group and (13.84 ±3.14) points in the control group, the differences were significant( t value was 3.653, P<0.01). Conclusions:The use of group painting art therapy in patients with schizophrenia during rehabilitation can promote the improvement of negative symptoms and improve the cognitive and social functions of patients.

ABSTRACT

@#Objective    To evaluate the clinical outcomes of larynx-preserving limited resection with total thoracic esophagectomy and gastric pull-up reconstruction for the treatment of cervical esophageal squamous cell carcinoma (ESCC) without tumor involvement of the larynx and hypopharynx compared with the upper thoracic ESCC. Methods    Retrospective and comparative analysis of consecutive patients with cervical and upper thoracic ESCC who underwent R0 surgical resection from 2006 to 2011 in our center was performed. Kaplan-Meier method was used to calculate the patients’ survival. Results    In total, 44 pairs of patients, including 71 males and 17 females with an average age of 60.66±8.49 years were enrolled in the study after propensity score matching. The baseline characteristics of the two groups of patients were well balanced. There was no statistical difference in the operation time (P=0.100), blood loss (P=0.685), mortality rate in 30 days (P=1.000), total complication rate (P=0.829), cervical anastomosis leakage (P=0.816), mechanical ventilation (P=1.000), normal oral diet within 15 days (P=0.822) and anastomosis recurrence rate (P=0.676) between the two groups. Survival analysis showed that there was no statistical difference in survival time between the cervical group [31.83 (95%CI 8.65-55.02) months] and upper thoracic group [37.73 (95%CI 25.29-50.18) months, P=0.533]. The 5-year survival rates were 32.6% and 42.1%, respectively. Conclusion    Larynx-preserving limited resection  with total thoracic esophagectomy and gastric pull-up reconstruction for the treatment of cervical ESCC without involvement of the larynx and hypopharynx may result in a similar clinical outcome to upper thoracic ESCC.
