ABSTRACT

Objective:To analyze imaging features of lymphoepithelial carcinoma (LEC) of salivary gland through conventional CT, MRI and functional MRI.Methods:From March 2010 to March 2020, a total of 75 patients with salivary gland LEC who were initially diagnosed and confirmed by postoperative pathology were retrospectively collected in the Ninth People′s Hospital Affiliated to Shanghai Jiaotong University Medical College. The preoperative CT and MRI findings were analyzed. Information including location, size, shape, boundary, density/signal intensity and enhancement degree of lesions were evaluated by conventional CT and MRI. The ADC value and time-intensity curve (TIC) pattern of lesions were measured from DWI and dynamic contrast enhanced (DCE)-MRI.Results:Among 75 cases of LEC in salivary gland, 56 cases had solitary lesions, 38 cases were round/oval or irregular, 34 cases were irregular morphology. Only 1 case exhibited calcification and 5 cases had necrotic regions. In 68 cases with CT images, 28 cases showed moderate enhancement and 30 cases showed intense enhancement. In 12 cases with MRI, 11 cases showed iso-intensity on T 1WI and 12 cases showed slightly hyperintensity on T 2WI. After contrast injection, 11 cases showed homogeneous enhancement and all of the 12 cases showed intense enhancement. The ADC value of LEC in salivary gland was (0.68±0.05)×10?3 mm 2/s and the TIC type of all the 12 cases was type Ⅱ (fast rising platform type). Conclusion:The LEC of salivary gland is single, has homogeneous texture, moderate enhancement and low ADC value. DCE-MRI shows type Ⅱ TIC curve. Morphological features combined with functional MRI features are helpful for accurate preoperative imaging diagnosis and differential diagnosis.

ABSTRACT

Objective:To determine the prevalence of AIDS/HIV, sexual behavior, knowledge, and access to HIV-related services among college students in Taizhou from 2016 through 2018, and provide scientific evidence for developing targeted strategies and measures. Methods:Based on the National HIV/AIDS Sentinel Surveillance, a cross-sectional survey was conducted annually among college students in three sentinels by a multi-stage cluster sampling across Taizhou, using questionnaire and laboratory examination. Results:A total of 4 185 college students were surveyed during 2016–2018, in which the proportion of reporting sexual behavior was 7.7%, with 58.4% using condom at. Sexual behavior, with fixed sexual partners, casual partners, commercial partners, and homosexual partners accounted for 68.7%, 23%, 4.0%, and 4.0%, respectively. Sexual experience and sexual behavior with fixed partners were statistically different among colleges and gender, which was much higher in male and vocational schools. The awareness rate of HIV/AIDS knowledge was 65.8%; 3.6% was found to have HIV voluntary counseling and testing, in which 7.8% had sexual behavior, indicating an upward trend over years. No college student tested positive for HIV from 2016 to 2018, and only one tested positive for anti-syphilis antibody and one positive for anti-hepatitis C antibody. Conclusions:Young male and vocational students in Taizhou are likely to have more sexual behavior and lower awareness on HIV/AIDS. College students have at-risk sexual behavior, insufficient awareness of HIV/AIDS, which may facilitate high risk of infection. It warrants further strengthening HIV/AIDS health education.

ABSTRACT

Objective:To investigate the association of muscle mass loss with atherosclerosis in elderly patients with type 2 diabetes mellitus(T2DM).Methods:A total of 322 patients with T2DM aged≥60 years old were divided into muscle mass loss group( n=152) and non-muscle mass loss group( n=170) according to their appendicular skeletal muscle mass index(ASMI). All participants underwent physical examination, dual-energy X-ray absorptiometry check, carotid and lower extremity ultrasound, as well as laboratory tests. Results:Among 322 patients, 49(15.22%) patients were suffered from sarcopenia and 152(47.2%) patients with reduced muscle mass. The carotid and lower extremity atherosclerosis grades in the muscle mass loss group were significantly higher than those in the non-muscle mass loss group( P<0.05), with lower body mass index(BMI), T-score, ASMI, uric acid, and homeostasis model assessment of insulin resistance index( P<0.05). Multivariate logistic regression analysis showed that carotid atherosclerosis and lower extremity atherosclerosis were risk factors for muscle mass loss while BMI and 25-(OH)D 3 were protective factors for muscle mass loss. There existed a consistency in carotid atherosclerosis grade and lower extremity atherosclerosis grade of elderly patients with T2DM( P<0.01). Conclusion:Atherosclerosis has a predictive value for early sarcopenia in elderly patients with T2DM.

ABSTRACT

Colorectal cancer patients with potential resectable liver metastases may benefit from hepatectomy or other local treatment to achieve R 0 resection or no evidence disease after conversion treatment by chemotherapy with or without target therapy. FOLFOX or FOLFIRI combined with cetuximab is appropriate for RAS and BRAF wide type and primary tumor at left-side colon cancer and rectal cancer. It is complex for RAS and BRAF wide type and primary tumor at right-side colon cancer or RAS or BRAF mutated patients. FOLFOXIRI combined with bevacizumab may be the first choice for those patients with young age and good performance score to achieve best conversion chance, while FOLFOX/CapeOx/FOLFIRI combined with bevacizumab could be the second choice. A surgical re-evaluation should be planned every 2 months after initiation of conversion treatment in multi-disciplinary treatment assessment. Once it is demonstrated conversion treatment is successful, surgery should be performed as soon as possible.

ABSTRACT

OBJECTIVE@#To investigate the nutritional status of children with cerebral palsy (CP) and the clinical effectiveness of Subjective Global Nutritional Assessment (SGNA) in nutritional assessment of hospitalized children with CP.@*METHODS@#A total of 208 children with CP, aged 1-5 years, who were hospitalized from April to October 2019 were enrolled as subjects. SGNA was used to investigate nutritional status, and the Z-score method recommended by the World Health Organization was used as a reference standard to validate the clinical effectiveness of SGNA.@*RESULTS@#The detection rate of malnutrition in children with CP was 42.3% by SGNA and 39.4% by the Z-score method (P>0.05). The application of SGNA showed high consistency between different evaluators (κ=0.621, P<0.001). With the Z-score method as the reference standard, SGNA had a sensitivity of 80.5%, a specificity of 82.5%, a positive predictive value of 75.0%, and a negative predictive value of 86.7%, and high consistency was observed between the two evaluation methods (κ=0.622, P<0.001). SGNA was moderately consistent with weight-for-age Z-score and height-for-age Z-score (κ=0.495 and 0.478 respectively, P<0.001) and was poorly consistent with weight-for-height Z-score (κ=0.197, P<0.05).@*CONCLUSIONS@#There is a relatively high incidence rate of malnutrition in children with CP. SGNA can be used as a tool to assess the nutritional status of children with CP.

ABSTRACT

Objective:To explore the related factors of muscle mass loss in patients with type 2 diabetes mellitus, and to provide evidence for prevention of sarcopenia in type 2 diabetic patients.Methods:A cross-sectional survey was used to select type 2 diabetic patients admitted to the Department of Endocrinology, Affiliated Hospital of Qingdao University from January 2019 to August 2019. All subjects underwent dual-energy X-ray absorptiometry check. According to the diagnostic criteria of the Asian Working Group for Sarcopenia (AWGS), the subjects were divided into a muscle reduction group and a non-muscle reduction group. Data including age, gender, body mass index, course of disease, blood index, urinary albumin-creatinin ration (UACR), and appendicular skeletal muscle index (ASMI) were collected. The relevant clinical data of viscera fat/subcutaneous fat (VAT/SAT), percentage of abdominal fat/percentage of hip fat (A/G), grip strength, and pace were analyzed for the related factors of muscle mass loss in type 2 diabetic patients.Results:A total of 369 patients with type 2 diabetes were enrolled, including 42 patients with sarcopenia (an incidence rate of 11.38%), and 155 patients with reduced muscle mass (an incidence of 42.01%). Age, systolic blood pressure, high density lipoprotein-cholesterol, UACR, VAT/SAT, and A/G in the muscle reduction group were higher than those in the non-muscle reduction group ( P<0.05). The parameter of body mass index, homeostasis model assessment for insulin resistance, estimated glomerular filtration rate (eGFR), ASMI, and grip strength were lower in the muscle reduction group than in the non-muscle reduction group ( P<0.05). Multivariate logistic regression analysis showed age, UACR, A/G, and VAT/SAT were risk factors for muscle loss, body mass index, eGFR, and grip strength were protective factors for muscle mass reduction. Conclusion:It is of great practical significance for type 2 diabetic patients, especially those with advanced age, central obesity, low body mass index, low grip strength, low glomerular filtration rate, and high UACR to perform an early screening and to begin an early intervention.

ABSTRACT

Schisandrol B (SolB) is one of the active constituents from a traditional Chinese medicine Schisandra chinensis or Schisandra sphenanthera. Our previous studies found that SolB exerts hepatoprotective effects against drug-induced liver injury and promotes liver regeneration. We further found that SolB significantly induces liver enlargement but the mechanisms remain unclear. The purpose of this study was to investigate the change of lipidome in liver tissues during SolB-induced hepatomegaly. The animal experiment protocol was approved by the Institutional Animal Care and Use Committee at Sun Yat-sen University. Serum and liver samples of male C57BL/6 mice were collected after intraperitoneal injection of SolB (100 mg·kg-1·d-1) for 5 days. Lipidomics analysis was performed using Q Exactive UHPLC-MS/MS system. The results showed that SolB significantly promoted liver enlargement in mice without liver injury and inflammation. Lipid accumulation was observed in the liver tissues after SolB treatment. Thirty-five lipids were identified with significant change and triglycerides (TG) were found to have the most significant increase in SolB-treated group, indicating the increase of energy production during SolB-induced hepatomegaly. This study reveals the impact of SolB on lipid metabolism and provides a potential explanation for liver enlargement induced by SolB.

ABSTRACT

OBJECTIVE@#To observe the clinical effect of fire needling on dysphagia due to pseudobulbar paralysis after stroke and to compare the difference in clinical effect between fire needling and swallowing function rehabilitation training.@*METHODS@#A total of 76 patients with dysphagia due to pseudobulbar paralysis after stroke were randomly divided into an observation group and a control group, 38 cases in each group (1 case dropped out in the control group). The both groups were based on conventional western medication treatment. Fire needle pricking was exerted at Lianquan (CV 23), Fengchi (GB 20), Wangu (GB 12), Shuigou (GV 26), Neiguan (PC 6) and Zusanli (ST 36) without needle retaining every other day in the observation group. The control group was treated with the swallowing function rehabilitation training. In both groups, treatment for 2 weeks was as one course and 2 courses of treatment with 2-day interval were required. After treatment, swallowing scores of Fujishima Ichiro and swallow quality of life questionnaire (SWAL-QOL) scores were observed in both groups, and the clinical effect was compared. Follow-up of swallowing scores of Fujishima Ichiro in 4 weeks after treatment was completed to evaluate the clinical effect.@*RESULTS@#The clinical effective rates after treatment and follow-up were 92.1% (35/38) and 94.7% (36/38) in the observation group, higher than 75.7% (28/37) and 83.8% (31/37) in the control group (<0.05). After treatment, the swallowing scores of Fujishima Ichiro and SWAL-QOL scores were increased in the two groups (<0.05), and those in the observation group were higher than the control group (<0.05). The swallowing scores of Fujishima Ichiro were increased during follow-up in the two groups (<0.05).@*CONCLUSION@#Fire needling has a better effect than conventional rehabilitation training in the treatment of dysphagia due to pseudobulbar paralysis after stroke, which can obviously improve the swallowing function and quality of life in patients with dysphagia.

ABSTRACT

Tumor biomarkers play important roles in tumor growth, invasion, and metastasis. Imaging of specific biomarkers will help to understand different biological activities, thereby achieving precise medicine for each head and neck squamous cell carcinoma (HNSCC) patient. Here, we describe various molecular targets and molecular imaging modalities for HNSCC imaging. An extensive search was undertaken in the PubMed database with the keywords including "HNSCC," "molecular imaging," "biomarker," and "multimodal imaging." Imaging targets in HNSCC consist of the epidermal growth factor receptor, cluster of differentiation 44 variant 6 (CD44v6), and mesenchymal-epithelial transition factor and integrins. Targeted molecular imaging modalities in HNSCC include optical imaging, ultrasound, magnetic resonance imaging, positron emission tomography, and single-photon emission computed tomography. Making the most of each single imaging method, targeted multimodal imaging has a great potential in the accurate diagnosis and therapy of HNSCC. By visualizing tumor biomarkers at cellular and molecular levels in vivo, targeted molecular imaging can be used to identify specific genetic and metabolic aberrations, thereby accelerating personalized treatment development for HNSCC patients.

ABSTRACT

The infructescence of Platycarya strobilacea is the dry infructescence of P. strobilacea, which is a traditional medicinal plant in China. It has functions of clearing up heat and detoxification, dispelling wind and relieving pain, activating blood circulation and removing stasis, clearing orifices and expelling pus. It is commonly used by people to treat various complications caused by acute and chronic rhinitis, sinusitis and acute upper respiratory tract infection, and is a kind of Chinese medicine with excellent development space and utilization value and has broad market prospects. There are many chemical constituents in the infructescence of P. strobilacea, including volatile oils, Phenols, flavonoids, terpenoids, carbohydrates and other compounds. Among them, volatile oils are the most abundant, but lack of correlated activity studies. Phenolic compounds, flavonoids and terpenoids are the main pharmacogenetics constituents. However, few of these compounds have been isolated and identified. Modern pharmacological studies have shown that the infructescence of P. strobilacea has many pharmacological activities, such as anti-tumor, anti-virus, anti-inflammatory and bacteriostasis, anti-aging, growth promotion, hypotension and sedation, but the existing studies mainly focus on anti-virus, anti-inflammatory and bacteriostasis, anti-tumor effects, and other activities have not been further explored. In the future, the chemical constituents and pharmacological activities of the infructescence of P. strobilacea should be studied in depth, and its mechanism should be further clarified so that it can be more fully and reasonably applied. By consulting domestic and foreign literature in recent years in CNKI, VIP database, Wanfang date, PubMed and other databases. The chemical constituents, pharmacological effects and clinical application of the infructescence of P. strobilacea were summarized and expounded its research progress in order to provide theoretical reference for further research and further development and application of the Infructescence of P. strobilacea.

ABSTRACT

OBJECTIVE: To observe the effect of deep acupuncture of Tiantu (CV22), etc. in combination with rehabilitation training on swallowing function of patients with post-stroke dysphasia. METHODS: A total of 70 patients suffering from post-stroke dysphagia were randomly divided into control group (conventional acupuncture+ swallowing rehabilitation training) and treatment group (deep acupuncture of CV22 + rehabilitation training, n= 35 cases in each group). The swallowing rehabilitation procedure was conducted 30 min every time, twice daily, 5 times a week for 3 weeks. In patients of the treatment group, after deep insertion (about 80 mm) along the posterior margin of the manubrium sterna, the filiform needle in CV22 was lifted and thrusted repeatedly 9 times till the patient experienced a feeling of foreign matter blocking, followed by retaining the needle for 30 min. For patients of the control group, Lianquan (CV23) was punctured with 3 acupuncture needles (one vertical needling and bilateral slope needling toward the tongue root), and Fengfu (GV16), bilateral Bailao (EX-NH23), bilateral Renying (ST9) and bilateral Jialianquan (Extra) were punctured vertically with filiform needles. The treatment was conducted once daily, 5 times a week for 3 weeks. The swallowing function was evaluated by using Kubota water swallowing test (KWST) scale (0-5 points), Fujishima Ichiro rating scale (FIRS, 0-10 points), and video fluoroscopic swallowing study (VFSS, 0-10 points), separately. The therapeutic effect was also assessed according to the clinical scale scores and VFSS results. RESULTS: Following the treatment, of the two 35 cases in the control and treatment groups, 4 (11.43%) and 8 (22.86%) experienced marked improvement in their symptoms, 22 (62.86%) and 23 (65.71%) were effective, and 9 (25.71%) and 4 (11.43%) were failed, with the effective rates being 74.29% and 88.57%, respectively. After the treatment, the KWST score of the two groups were significantly decreased in comparison with their own pre-treatment (P<0.05), while the FIRS and VFSS scores of the two groups were considerably increased in comparison with their own pre-treatment (P<0.05). The therapeutic effects of the treatment group were obviously superior to those of the control group in the effective rate, lowering KWST score and in raising FIRS and VFSS scores (P<0.05).. CONCLUSION: Acupuncture plus swallowing rehabilitation training is effective in improving the swallowing function of stroke patients with dysphagia, and the deep acupuncture stimulation of CV22 is apparently better than conventional acupuncture in the therapeutic effect.

ABSTRACT

Perioperative treatment combined with radical resection is the major approach to cure non-metastatic colon cancer. A precise evaluation and perioperative treatment would probably improve the R0 resection rate, recurrence-free survival and overall survival of colon cancer patients. Recently, individualized treatment is the mainstream due to the development of molecular pathology and multi-disciplinary therapy. The indications and course of perioperative treatment and preoperative neoadjuvant therapy of colon cancer are still in intense discussion. The present review will mainly discuss three topics. Firstly, the various reaction of adjuvant therapy to stage II colon cancer is caused by patients′ heterogeneity. Choosing stratified treatment for these patients according to clinical and molecular pathological features is the future. Secondly, we discuss the adjuvant chemotherapy course for stage III colon cancer according to the Chinese Society of Clinical Oncology (CSCO) guideline and the progress of this field. Lastly, we summarize the status and significance of colon cancer neoadjuvant therapy.

ABSTRACT

Objective To explore the value of texture analysis on ADC maps in the preoperative prediction of histological grade of tongue and mouth floor squamous cell carcinoma (SCC). Methods Forty?nine pathologically confirmed tongue and mouth floor SCC with definite grading from May 2015 to June 2018 were retrospectively analyzed, including 21 cases of gradeⅠ, 21 cases of gradeⅡand 7 cases of gradeⅢ. All subjects underwent preoperative MRI examination with DWI included. Two doctors delineated whole tumor region of interest and extracted texture parameters by the 3D Slicer software, including 8 histogram parameters, 11 grey?level co?occurrence matrix (GLCM) parameters and 7 gray?level run?length matrix (GLRLM) parameters. Intraclass correlation coefficient (ICC) was used to evaluate the inter?observer delineation agreement, and the texture parameters with excellent reproducibility (ICC>0.8) were used for analysis only. Mann?Whitney U test was used to compare the differences of ADC texture parameters between grade Ⅰ and grade Ⅱ?Ⅲ SCCs. Stepwise logistic regression was used to determine the independent predictors and to build combined model. ROC analysis was used to explore the performance of texture parameter and model in predicting histological grade of tongue and mouth floor SCCs. Pearson correlation coefficient was used to evaluate the correlation between texture parameters with statistical significance. Results (1) Excellent inter?observer delineation agreement (ICC: 0.81-0.98) was observed in 69.23% (18/26) texture parameters, including 6 histogram parameters, 7 GLCM parameters and 5 GLRLM parameters. (2) Among histogram parameters, significantly higher 10 percentile ADC value (ADC10) and significantly lower energy and entropy were shown in gradeⅠcompared with gradeⅡandⅢSCCs (all P<0.05). Among GLCM parameters, significantly lower joint entropy, difference entropy, sum entropy, difference variance, difference average and contrast were shown in grade Ⅰ SCCs (all P<0.05). Among GLRLM parameters, significantly lower gray?level nonuniformity and run?length nonuniformity were shown in gradeⅠSCCs (all P<0.05). ADC10 and entropy were identified as independent predictors. The ADC10 and entropy were 960(913, 1 178)×10?6mm2/s and 4.32(4.06, 4.76) in gradeⅠSCCs, and 888(816, 987)×10?6mm2/s and 4.88(4.57, 5.29) in gradeⅡ?ⅢSCCs respectively. The area under ROC curve (AUC) of ADC10, entropy and combined model were 0.72, 0.75, 0.81. (3) Significant correlation (|r|≥0.5) was observed among 52.73% (29/55)texture parameters with statistical significance. Conclusion Texture analysis on ADC maps can provide more quantitative information, which can be more accurately in discriminating grade Ⅰfrom gradeⅡ?Ⅲtongue and mouth floor SCCs.
