ABSTRACT

Five patients with mediastinal bronchogenic cyst (MBC) were treated with endoscopic submucosal tunnel dissection (ESTD) between January 2018 and October 2019 at the Department of Gastroenterology in Henan Provincial People′s Hospital. Lesions were located in the middle or lower esophageal level, with diameters≤3.5 cm. The tunnel establishment time was 13-18 min, and the tumor stripping time was 30-51 min. The number of titanium clips used for tunnel closure was 5-8. The tumors were completely resected. No major bleeding or hypoxemia occurred during the operation and no serious adverse reactions occurred after the operation. Postoperative pain scores were all ≤3. The hospital stay was 4-7 days. There was no tumor residue and recurrence during 4-23 months of follow-up.It is suggested that ESTD for MBC which derived from post mediastinum and located at the lower or middle level esophagus is safe and effective.

ABSTRACT

Objective:To explore the application effect of magnetic resonance imaging (MRI) sequence experiment based on virtual simulation software in undergraduate teaching of medical imaging technology.Methods:Fifty-six undergraduate students from the Batch 2015 and Batch 2016 medical imaging technology of West China Clinical Medical College of Sichuan University were recruited in this study. They were divided into 2 groups: experimental group (Batch 2016) and control group (Batch 2015). The experimental group adopted the teaching method based on virtual simulation experiment, and the control group used the teaching method based on traditional small-sized magnetic resonance. The after-class test scores and final exam scores of the two groups of students were compared, and the questionnaire survey on teaching effectiveness was conducted for students in the experimental group SPSS 21.0 was used for ttest and Mann-Whitney Utest. Results:The scores of theoretical knowledge and the final grades in the experimental group were significantly higher than those of the control group [(84.55 ± 6.57) points vs. (79.37 ± 6.13) points; (90.03 ± 4.72) points vs. (80.06 ± 7.29) points, all P< 0.05). The effective recovery rate of the questionnaires was 100%, and the questionnaire survey showed that the experimental group was significantly superior to the control group in such four aspects as increasing subject interest, expanding relevant knowledge, solving clinical work, and promoting teamwork ( P< 0.05). Conclusion:In MRI sequence teaching, the teaching method based on virtual simulation software can increase the students' interests in learning, strengthen their understanding of MRI principles, then effectively improve the teaching effect of medical imaging undergraduate education.

ABSTRACT

Clinical practice of medical imaging technology undergraduates is a key link in the transformation from imaging technology students to imaging technologists. However, there are a series of problems leading to poor practice effect, e.g., imaging technology involves a lot of learning contents, and the teachers' level is uneven. Based on the above problems, some improvements have been implemented, including the establishment of the admission lecture system and tutor responsibility system, application of pluralistic teaching methods, standardizing the examination system of interns, flexible adjustment of practice time arrangements, training of practice teaching team, and so on. Finally, the quality and effect of undergraduate practice teaching in medical imaging technology has been improved significantly.

ABSTRACT

Objective:To understand the risk characteristics of high-risk population of chronic disease in Shanghai, and provide theoretical basis for screening management and health intervention. Methods:The data from the 2013 Shanghai Non-communicable and Chronic Diseases Surveillance was used for analysis. People (aged 35 and over) who had no diagnosis of hypertension, diabetes and dyslipidemia but met the criteria for high-risk groups of chronic diseases were included in the study. Finally, 3 682 participants were included. Results:In this high-risk population, 62.90% of the subjects has total serum cholesterol level of 5.2-6.2 mmol/L, 35.88% had blood pressure level of (130-139)/(85-89) mmHg, 30.50% had abdominal obesity, 27.68% were current smokers, and 8.75% had fasting blood glucose level of 6.1-7.0 mmol/L. Among the different risk characteristics, the detection rate of smoking risk in men was higher than that in women (64.51% vs. 1.49%). On the contrary, the detection rate of waist circumference and serum total cholesterol risk in women was higher than that in men (34.90% vs. 24.31% and 72.30% vs. 49.67%, respectively). The differences were statistically significant (P<0.05). The detection rates of the five high-risk characteristics were not the same in all age groups. The detection rate of blood pressure risk was relatively low, and the cholesterol risk was relatively high in the highly educated population. The blood pressure risk was the highest among agricultural practitioners (42.26%). The detection rate of smoking risk was the highest in rural areas (31.45%), and the risk of cholesterol was the highest in urban areas (68.54%). The differences were statistically significant (P<0.05). Among the high-risk groups of chronic diseases in Shanghai, the distribution of high-risk characteristics in genders, ages, and occupational types were not the same and the differences were statistically significant (P<0.05). Conclusions:The level of risk characteristics among high-risk groups of chronic diseases in Shanghai is relatively high. Relevant departments should carry out targeted health interventions for different populations to reduce the level of risk factors in high-risk groups of chronic diseases and control the potential risk of chronic diseases.

ABSTRACT

Objective:To understand the epidemiological characteristics of high-risk population of hypertension in Shanghai, and to provide references for health management and targeted lifestyle intervention of the high-risk population in community. Methods:The data from the 2013 Shanghai Non-communicable and Chronic Diseases Surveillance were used. The subjects who met the criteria of high-risk population of hypertension were included, and 11 753 subjects were finally identified, to analyze the distribution and level of risk characteristics. Result:Among six high-risk characteristics of hypertension, the detection rate of high salt in diet was the highest (55.3%), followed by overweight/obesity (44.0%), family history of hypertension (41.6%), and blood pressure level of (130-139)/(85-89) mmHg (31.7%). The detection rate of excessive drinking was the lowest (5.0%). The percentage of population with one or two high-risk characteristics was higher than that with three or more high-risk characteristics (76.9% vs. 23.1%). Systolic blood pressure, diastolic blood pressure, fasting plasma glucose level, and body mass index in the male high-risk group were higher than those in the female group, and the differences were statistically significant (P<0.05). Systolic blood pressure, diastolic blood pressure, fasting plasma glucose level, body mass index and daily salt intake were different between different age groups, educational level and occupational types (P<0.05). Systolic blood pressure, diastolic blood pressure, body mass index and daily salt intake were significantly different among high-risk groups with different marital status (P<0.05). The daily salt intake and systolic blood pressure levels of high-risk population in different areas were significantly different (P<0.05). Conclusion:We should identify high-risk groups of hypertension as early as possible and actively carry out community health management and targeted lifestyle interventions. The focus should be on the groups and individuals with high-risk characteristics such as dietary high salt and overweight/obesity, male, middle-aged and low-educated groups. In this way, we can reduce the level of high-risk characteristics, prevent and delay the occurrence of hypertension.

ABSTRACT

OBJECTIVE: To explore the therapeutic effect of tetrandrine(TET) on silicosis model rats and its toxic effect on liver and kidney function. METHODS: The specific pathogen free healthy male Wistar rats were randomly divided into the control group, the model group and the TET group, with 14 rats in each group. By un-exposure tracheal injection method, the rats in the model and TET groups were given one-time tracheal infusion of free silicon dioxide suspension with a mass concentration of 50 g/L to establish the rat model of silicosis. Rats in the control group were infused with 1 mL of 0.9% sodium chloride solution with the same method. On the second day after the model was established, the TET group was given 30 mg/kg body mass of TET solution by gavage. The other two groups were given the same amount of 0.9% sodium chloride solution. The treatment was once per day, six times per week. Seven rats in each group were sacrificed on the 28 th and 56 th days after modeling. The morphological change of the lung, liver and kidney tissues of each group was observed. The enzyme-linked immunosorbent assay was used to detect the level of tumor necrosis factor-α(TNF-α), transforming growth factor-β1(TGF-β1), interleukin(IL)-1β and IL-6, in the lung tissues of rats in each group. The activities of aminotransferase(ALT), aspartate aminotransferase(AST) and the levels blood urea nitrogen(BUN), creatinine(CRE) were detected by automatic biochemical analyzer. RESULTS: The lung organ coefficients of rats in the TET group were lower than those of the model group on the 28 th and 56 th days(all P<0.05). The lung organ coefficient of the rats in the TET group on the 56 th day was higher than that in the same group on the 28 th day(P<0.05). The lung tissue structure of the control group was normal. After modeling, the lung tissues of rats in model group showed different degrees of pathological changes such as alveolar structure destruction, inflammatory cell infiltration, and fibrosis on the 28 th and 56 th days. The degree of pathological changes in TET group was less than that of the model group. In the lung tissues of rats in the model group, the levels of TNF-α, TGF-β1, IL-1β and IL-6 were higher than those of the control group(all P<0.01). The levels of TNF-α, TGF-β1, IL-1β and IL-6 in the lung tissues of rats in the TET group were lower than that of the model group(all P<0.01), but there was no statistically significant difference when compared with the control group(all P>0.05). The activities of ALT and AST in the TET group were higher than those in the model group and the control group(all P<0.01). The level of serum BUN in TET group was higher than that in control group(P<0.01), but it showed no statistical difference when compared with the control group(P>0.05). The level of serum CRE in each group showed no significant difference(P>0.05). There were no abnormal pathological changes found in the liver and kidney tissues of rats in each group at different times. CONCLUSION: TET can reduce the inflammatory response in silicosis rats and improve lung tissue fibrosis; however, the therapeutic dose may have certain toxicity to the liver and kidney of the silicosis rats.

ABSTRACT

OBJECTIVE@#To investigate the effects of different acupuncture manipulations on Deqi sensations and surface myoelectricity, and explore the correlation between Deqi sensations and needling manipulations.@*METHODS@#Forty-five healthy participants accepted twirling, lifting-thrusting, and twirling plus lifting-thrusting manipulanions at right Zusanli (ST 36), respectively. The acupuncturist's and participants' Deqi sensations were collected by MGH Acupuncture Sensation Scale (MASS). The intensity and occurrence rate of soreness, dull pain, pressure, heaviness, fullness, numbness, sharp pain, warmth, coolness, and throbbing feelings of participants, and tightness, smooth, and tangle feelings of acupuncturist were measured. The correlation between the acupuncturist's and participant's Deqi sensations was analyzed. Surface electromyogram (EMG) were recorded before, during and after needling in 30 participants. The integrated EMG (iEMG), mean power frequency (MPF) and media frequency (MF) were analyzed.@*RESULT@#Both fullness and soreness of participants and tightness of acupuncturist were the most frequently occurred ones. A positive correlation between participants' fullness and acupuncturist's tightness was observed during the three aforementioned needling manipulations (P1). Almost all the needling sensations measured in the present study could be induced by the three needling manipulations. However, strength of Deqi sensations was exhibited as lifting-thrusting > twirling plus lifting-thrusting > twirling according to MASS index. The iEMG values were increased and MPF, MF values were decreased during needling compaired to those before needling, especially during lifting-thrusting (P<0.01).@*CONCLUSIONS@#The intensity and occurrence rate of the different Deqi sensations induced by different needling manipulations were basically similar. The fullness and soreness were both the most frequently induced Deqi sensations. The strongest Deqi sensation could be induced by lifting-thrusting manipulation. There is a positive correlation between participants' fullness and acupuncturist's tightness during the three needling manipulations. The myoelectricity around the acupoint is related to Deqi responses. (Registration No. AMCTR-IOR-20000314).

ABSTRACT

OBJECTIVE@#To analyze the characteristics, prognosis and risk factors of bloodstream infection in patients with hematological malignancies in the tropics, so as to provide evidence for the prevention and treatment of bloodstream infection.@*METHODS@#The clinical features, blood culture results and prognosis of patients with bloodstream infection in patients with hematological malignancies admitted to Hainan Hospital of PLA General Hospital were retrospectively studied.@*RESULTS@#The most common primary infection site of the 81 patients with hematological malignancies was lung (46.91%), followed by PICC (11.11%). The detection rate of Gram-positive bacteria and Gram-negative bacteria in the blood culture was 60.98% and 30.02%, respectively. Coagulase-negative staphylococci was the most common Gram-positive bacteria resulting in bloodstream infection in our study. Of the Gram-negatives, Klebsiella pneumoniae (34.38%) was predominant, followed by Escherichia coli (18.75%) and Pseudomonas aeruginosa (18.75%). Gram-positive bacteria was highly sensitive (100%) to vancomycin, linezolid and tigecycline. Study showed that Gram-negative bacteria had low sensitive to quinolones, in particular, the resistance rate of Escherichia coli to quinolones was as high as 83.33%. In terms of overall survival (OS), the 30-days OS of patients with Gram-negative and Gram-positive septicemia was 77.42% and 92.00%, respectively. There was no statistically significant difference between the two groups. Multivariate analysis revealed that septic shock (P=0.001, RR=269.27) was an independent risk factor for 30-day mortality, and remission status (P=0.027, RR=0.114) was an independent predictor of a favourable outcome of bloodstream infection in patients with hematological malignancies.@*CONCLUSION@#Gram-positive bacteria are the main pathogens causing bloodstream infections in patients with hematological malignancies in the tropics. Improving the care of PICC is an important measure to reduce the incidence of bloodstream infection in patients with hematological malignancies in the tropics. A correct treatment relieving disease and effective prevention and treatment of septic shock can reduce mortality of patients with bloodstream infection in patients with hematological malignancies in the tropics.

ABSTRACT

The article was to study the effect of local photodynamics therapy combined with carbon dioxide lattice laser - "light needles" for the treatment of basal cell carcinoma (BCC). 5-Aminolevulinic acid (5-ALA) cubic liquid crystal using glyceryl monostearate (GMO) as the substrate was prepared. The cytotoxicity of 5-ALA cubic liquid crystal combined with light needles in vitro were evaluated. The pharmacodynamics study of 5-ALA cubic liquid crystal combined with light needles of high or low energy for BCC was carried out based on the pathological changes, tumor volume, vascular endothelial growth factor (VEGF) expression and the recurrence rate, which has been approved by the Ethics Committee of Beijing Institute of Radiation Medicine. The cubic liquid crystal was isotropic with the lattice of PN3M. The cytotoxicity of 5-ALA cubic liquid crystal combined with light needles was much higher than that of 5-ALA or light needles alone. Compared with light needles or photodynamic therapy alone, 5-ALA cubic liquid crystal combined with light needles of high energy could prevent the BCC metastasis and of low energy could inhibit BCC growth. It demonstrated the obvious therapeutical effects for BCC. 5-ALA cubic liquid crystal combined with light needles can effectively treat BCC, which provides a new choice for clinical BCC treatment.

ABSTRACT

This study integrates metabolomics and network pharmacology techniques to systematically analyze the possible mechanism of Pudilan Xiaoyan oral liquid (PDL) in the treatment of acute respiratory infections. GC-MS metabolomics analysis found 8 endogenous metabolites, 3-phosphoglycerate, α-aminoadipate, D-ribulose-5-phosphate, β-mannosylglyceric acid, D-fructose, urea, D-maltose and ornithine in the serum of mice with acute respiratory infection induced by LPS; these substances can be used as biomarkers for PDL use in the treatment of acute respiratory infections. Biological network studies revealed 10 potential targets for intervention by PDL in the glycolysis and pentose phosphate pathways, including GPI, G6PD, H6PD, PFKM, TALDO1, TKT, GAPDH, HK1, PKLR and TPI1. All animal experiments were carried out with approval of the Animal Ethics Committee of Nanjing University of Chinese Medicine. Our findings indicate that the strategy of combining metabolomics and network analysis can provide information on the possible mechanism of PDL in acute respiratory infections, and reveal that PDL may ameliorate the pathological process of acute respiratory infections by regulating disordered metabolic pathways.

ABSTRACT

Biomarkers are defined as a characteristic that is objectively measured and evaluated as an indicator of normal biological processes, pathogenic processes, or pharmacological responses to a therapeutic intervention. Biomarkers can help the decision-making process for new drug research and development, provide guidance for the early clinical development of candidate drugs and reduce the risk of failure. Therefore, as a key factor in the development of new drugs, the discovery and research on biomarkers has increased the interest of the pharmaceutical industry and regulatory agencies. Guidelines on the development and use of biomarkers have been issued by drug regulatory agencies including the EMA, FDA and ICH. Biomarkers are encouraged to be used to facilitate drug development by these relevant regulatory agencies, and also to be used to monitor the safety and efficacy of drugs in post-marketing drug surveillance. The application of biomarkers is encouraged at different stages of a drug's life cycle, including at the stage of basic science research and target identification, prototype design or discovery, preclinical development, clinical development, FDA filling/approval and launch, as well as post-marketing was reviewed. The identification, development, and application of biomarkers in pharmaceutical research is discussed.

ABSTRACT

The research on the historical production areas of Dao-di herbs is of great value to the quality evaluation, production base and protection for geographic indications of Dao-di herbs. Current studies mostly focused on the sorting of written sources, but neglected the excavation of image records such as historical maps and topographic maps. This paper aims at exploreing the geographical scope and evolution mode of historical production area of the Dao-di herbs by combining the method of historical map labelling with the traditional literature and historical research methods. It can be divided into three steps: production area name extraction, historical map labelling and textual research on the historical production area of Dao-di herbs. This method may provide a better way to show the geographical scope and topographic features of the historical production areas of Dao-di herbs through historical maps labelling, which is essential to further explore the evolution of production areas of Dao-di herbs from ancient times to the present by comparing historical maps of different periods, and may be helpful to discover the reasons for the formation and evolution of historical producing areas of Dao-di herbs from different perspectives such as environment, climate, humanities, economy, policy, etc. In addition, the historical map database can be used for map labelling to help establish the relationship between the dynasties, historical names, and change cha-racteristics of the scope of the historical production areas of Dao-di herbs in the following research.
