ABSTRACT

Hepatocellular carcinoma (HCC) is the second leading cause of disease-related death in China and greatly threatens the health of residents. Recent studies have shown that traditional Chinese medicine plays an important role in the comprehensive treatment of HCC. Huaier granules have been recommended for the treatment of HCC, and its mechanism of action includes inhibiting angiogenesis, inhibiting the proliferation of HCC cells, inhibiting invasion and metastasis, inducing cell apoptosis, and regulating immune function. This article summarizes the research advances in the anti-HCC mechanism of Huaier granules and its application in clinical practice, in order to provide a reference for subsequent research and clinical treatment.

ABSTRACT

Objective To investigate the clinical effect of simultaneous surgical resection of hepatic and pancreatic lesions versus systemic chemotherapy in treatment of resectable pancreatic cancer with liver metastasis (PCLM). Methods A retrospective analysis was performed for related data of the patients with PCLM who were admitted to Shengjing Hospital of China Medical University from January 2013 to May 2020, and the patients with resectable PCLM were screened out and then divided into surgery group and chemotherapy group. The propensity score matching (PSM) method was used to reduce the impact of data bias and confounding factors. The independent samples t -test or the Mann- Whitney U test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups. The Kaplan-Meier method was used to calculate survival time, and the log-rank test was used for evaluation. The univariate and multivariate Cox regression models were used to investigate the independent risk factors for survival. Results A total of 56 patients with resectable PCLM were screened out, with 33 patients in the surgery group and 23 patients in the chemotherapy group, and there were 15 patients in each group after PSM. The surgery group had a significantly shorter median overall survival time than the chemotherapy group before PSM (6.6 months vs 10.4 months, χ 2 =4.476, P =0.034) and after PSM (6.4 months vs 10.5 months, χ 2 =4.309, P =0.038). The multivariate Cox regression analysis showed that poorly differentiated tumor (hazard ratio [ HR ]=4.945, 95% confidence interval [ CI ]: 1.980-12.348, P =0.001) and absence of postoperative chemotherapy ( HR =3.670, 95% CI : 1.437-9.376, P =0.007) were independent risk factors for poor prognosis in patients with PCLM. Conclusion Compared with chemotherapy, simultaneous surgical resection of hepatic and pancreatic lesions fails to prolong the overall survival time of patients with resectable PCLM. Patients with poorly differentiated tumor and those without postoperative chemotherapy tend to have poor prognosis.

ABSTRACT

The bone formation promoter recombinant human parathyroid hormone 1-34 [PTH (1-34)] has a short half-life and low bioavailability. In this study, we prepared a biodegradable and temperature-sensitive hyaluronic acid-poly-N-isopropyl acrylamide (AHA-g-PNIPAAm), and further investigated its effects of PTH (1-34) release and cell behavior as drug carrier. The structure of AHA-g-PNIPAAM was confirmed by hydrogen nuclear magnetic resonance spectroscopy and infrared spectroscopy. Next, PTH (1-34) loaded thermo-sensitive hydrogels were prepared by physical swelling method and their stability was investigated. The morphology of hydrogel was observed by scanning electron microscope. The minimum critical transition temperature and drug release behavior of hydrogels were investigated by ultraviolet spectrophotometry. The tetrazolium-based colorimetric assay (MTT assay) was used to investigate the toxicity and proliferation effects of PTH (1-34)-loaded thermo-sensitive hydrogel on mouse mononuclear macrophage RAW264.7 and mouse precranial osteoblasts MC3T3-E1. The effect of PTH (1-34)-loaded thermo-sensitive hydrogel on the differentiation of RAW264.7 was investigated by the tartrate-resistant acid phosphatase assay. The results showed that the PTH (1-34)-loaded thermo-sensitive hydrogel prepared in this study displayed regular three-dimensional honeycomb structure, and had good stability, thermo-sensitivity and sustained and controlled release properties, which could promote the proliferation of MC3T3-E1 cells more effectively and inhibit the differentiation of RAW264.7 into osteoclasts.

ABSTRACT

Liver-resident natural killer (LrNK) cells, as a type of newly discovered tissue-resident natural killer cells, have a strong immune killing function. During the development and progression of hepatocellular carcinoma (HCC), the function of LrNK cells is impaired and such cells may promote the progression of HCC by upregulating the expression of related immune checkpoints. Based on the latest research, this article reviews the immune function of LrNK cells and their role in the development and progression of HCC, in order to explore the application prospect of these cells in HCC immunotherapy.

ABSTRACT

Objective:To explore the relationship between arrival time and the retention in emergency room and the prognosis in patients with severe trauma.Methods:The clinical data of 1 738 emergency trauma patients in emergency intensive care from trauma center information system of the First Affiliated Hospital of Soochow University were extracted. The emergency retention was the time in the emergency room ≥ 4 h. The 24 h of the day was divided into three shifts at 8:00, 15:00 and 22:00. Logistic regression model was used to calculate the crude OR and adjusted OR after adjustment by age, sex and RTS of emergency shifts, and COX regression analysis was performed with emergency death as the endpoint. Results:Among the total of 1 738 patients with severe trauma, there were 852 (49.02%) cases of emergency retention. Taking the morning shift as the reference baseline, the risks of emergency retention in middle shift and night shift were increased gradually. The OR value of night shift was statistically significant ( P<0.01), and the crude OR and adjusted OR were 2.21 (95% CI: 1.71-2.86) and 2.36 (95% CI: 1.76-3.18), respectively. The univariate COX regression model indicated that the crude HR of night shift was statistically significant ( HR=0.26, 95% CI: 0.08-0.90, P=0.033). However, the multivariate COX regression model showed no statistically significant differences in the adjusted HR of middle shift ( HR=0.96, 95% CI: 0.43-2.14, P=0.914) and night shift ( HR=0.40, 95% CI: 0.08-1.85, P=0.238), respectively. Conclusions:The arrival time of emergency trauma patients might be a contributor to the emergency retention, and night shift patients are more likely to encounter retention, but there is no significant effect on patient death.

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@#: This study aims to investigate the relationship between aneurysm wall enhancement and clinical rupture risks based on the magnetic resonance vessel wall imaging (MR-VWI) quantitative methods. @*Methods@#: One hundred and eight patients with 127 unruptured aneurysms were prospectively enrolled from Feburary 2016 to October 2017. Aneurysms were divided into high risk (≥10) and intermediate-low risk group (<10) according to the PHASES (Population, Hypertension, Age, Size of aneurysm, Earlier SAH history from another aneurysm, Site of aneurysm) scores. Clinical risk factors, aneurysm morphology, and wall enhancement index (WEI) calculated using 3D MR-VWI were analyzed and compared. @*Results@#: In comparison of high-risk and intermediated-low risk groups, univariate analysis showed that neck width (4.5±3.3 mm vs. 3.4±1.7 mm, p=0.002), the presence of wall enhancement (100.0% vs. 62.9%, p<0.001), and WEI (1.6±0.6 vs. 0.8±0.8, p<0.001) were significantly associated with high rupture risk. Multivariate regression analysis revealed that WEI was the most important factor in predicting high rupture risk (odds ratio, 2.6; 95% confidence interval, 1.4–4.9; p=0.002). The receiver operating characteristic (ROC) curve analysis can efficiently differentiate higher risk aneurysms (area under the curve, 0.780; p<0.001) which have a reliable WEI cutoff value (1.04; sensitivity, 0.833; specificity, 0.67) predictive of high rupture risk. @*Conclusion@#: Aneurysms with higher rupture risk based on PHASES score demonstrate increased neck width, wall enhancement, and the enhancement intensity. Higher WEI in unruptured aneurysms has a predictive value for increased rupture risk.

ABSTRACT

@#Currently, titanium alloys are widely used in the field of stomatology; however, owing to long-term exposure to a complex microbial environment, dental plaques easily form on the surface of the materials, affecting the use efficiency and the service life of the materials. The antibacterial titanium alloy is a new kind of titanium alloy with antimicrobials added through surface modification or overall modification. Based on the location of antibacterial agents in titanium alloy materials, antibacterial titanium alloys can be divided into coating and alloy types. The antibacterial effect of coated antibacterial titanium alloy is good, but the disadvantage is that most of the coatings are not wear-resistant. The widely-used antibacterial agent of the alloy type is metal elements, which can be evenly distributed in the alloy, and the antibacterial properties are stable and long-lasting. Based on whether antibacterial agents can be released, antibacterial titanium alloys can be further divided into active antibacterial and passive antibacterial types. Active antibacterial type titanium alloys can release loaded antibacterial agents, and the antibacterial effect is more obvious, but the release duration of antibacterial agents is relatively short. Passive antibacterial titanium alloys exhibit an antibacterial effect by contact sterilization or inhibition of bacterial adhesion instead of releasing antibacterial agents. The antibacterial titanium alloy can inhibit the adhesion of bacteria on the surface of the material and prolong the service life of oral orthodontic appliances, implants and titanium plates. Moreover, the mechanical properties of the titanium alloy after antibacterial modification are not significantly affected, and the addition of antibacterial agents such as hydroxyapatite can increase the osteogenic function of the material. Therefore, the alloy has good application prospects in the fields of dental implant, orthodontic treatment and oral and maxillofacial surgery. However, most of the current studies on antibacterial titanium alloys are in vitro experiments, and their long-term clinical effects and antibacterial mechanisms are still unclear and need further study.

ABSTRACT

Objective To analyze the epidemiological characteristics of COVID-19 cases reported in Xianyang City from January to February 2020. Methods We retrospectively studied 17 COVID-19 patients diagnosed in Xianyang Central Hospital. The patients were characterized clinically and epidemiologically. Results The 17 patients included 10 male and 7 female, with an average age of(39.59±17.31)years. The median interval of time between onset and diagnosis was four days(1-10 days), whereas the median duration of COVID-19 was 16 days(3-23 days). Of the patients, six were mild, 10 were pneumonia, and one was severe. A total of 15 patients had fever as the onset, accompanied by fatigue, sore throat, sputum, vomit, muscle soreness; the other two patients were asymptomatic. There were no complications documented in all the patients. Patients had low levels of white blood cells and lymphocytes. Chest CT scan showed diverse diffuse ground-glass shadow. Eleven patients had travel history in Wuhan before the onset, four patients had contact with people who had travel history or residence history in Wuhan, and the other two patients did not report epidemiological exposure history. In addition, four of the 17 patients were clustered cases. Conclusion General population is susceptible to COVID-19. The majority of the confirmed cases have epidemiological exposure history. Routine examination, including white blood cell, lymphocyte count and CT scan may facilitate early diagnosis.

ABSTRACT

Background@#Type 2 diabetes mellitus (T2DM) is characterized by elevated fasting glucagon and impaired suppression of postprandial glucagon secretion, which may participate in diabetic complications. Therefore, we investigated the associations of plasma glucagon with estimated glomerular filtration rate (eGFR), albuminuria and diabetic kidney disease (DKD) in T2DM patients. @*Methods@#Fasting glucagon and postchallenge glucagon (assessed by area under the glucagon curve [AUCgla]) levels were determined during oral glucose tolerance tests. Patients with an eGFR <60 mL/min/1.73 m2 and/or a urinary albumin-to-creatinine ratio (UACR) ≥30 mg/g who presented with diabetic retinopathy were identified as having DKD. @*Results@#Of the 2,436 recruited patients, fasting glucagon was correlated with eGFR and UACR (r=–0.112 and r=0.157, respectively; P<0.001), and AUCgla was also correlated with eGFR and UACR (r=–0.267 and r=0.234, respectively; P<0.001). Moreover, 31.7% (n=771) presented with DKD; the prevalence of DKD was 27.3%, 27.6%, 32.5%, and 39.2% in the first (Q1), second (Q2), third (Q3), and fourth quartile (Q4) of fasting glucagon, respectively; and the corresponding prevalence for AUCgla was 25.9%, 22.7%, 33.7%, and 44.4%, respectively. Furthermore, after adjusting for other clinical covariates, the adjusted odds ratios (ORs; 95% confidence intervals) for DKD in Q2, Q3, and Q4 versus Q1 of fasting glucagon were 0.946 (0.697 to 1.284), 1.209 (0.895 to 1.634), and 1.521 (1.129 to 2.049), respectively; the corresponding ORs of AUCgla were 0.825 (0.611 to 1.114), 1.323 (0.989 to 1.769), and 2.066 (1.546 to 2.760), respectively. Additionally, when we restricted our analysis in patients with glycosylated hemoglobin <7.0% (n=471), we found fasting glucagon and AUCgla were still independently associated with DKD. @*Conclusion@#Both increased fasting and postchallenge glucagon levels were independently associated with DKD in T2DM patients.

ABSTRACT

Objective:Nuclear magnetic resonance spectroscopy (NMR) was used to detect the species and content of metabolites in urine of patients with inherited metabolic diseases, and to explore the application value of NMR technology in the diagnosis of inherited metabolic diseases.Methods:Urine samples were collected from 20 patients with inherited metabolic diseases diagnosed in Xinhua Hospital, Shanghai Jiaotong University School of Medicine from March to June 2019, including 9 cases of methylmalonic acidemia (MMA). NMR pulse length-based concentration determination and Gas chromatography mass spectrometry (GC/MS) semi-quantitative method were used to detect the composition of metabolites in urine samples of patients with inherited metabolic diseases, and the levels of abnormal metabolites in the two methods were analyzed.Results:NMR technology can detect the levels of characteristic metabolites significantly increased in the urine of patients with MMA, isovalerinemia, glutaric acidemia, propionic acidemia, 3-methylcrotonyl-CoA carboxylase deficiency, ornithine carbamyltransferase deficiency, Citrin deficiency, Canavan disease, tyrosinemia and lysinuria protein intolerance. The average is 8 times of the upper limit of the reference value, and the highest is 545 times. Compared to GC/MS, NMR technology can detect the levels of various metabolites such as organic acids, amino acids and sugars. In 9 cases of untreated MMA,the median levels of methylmalonic acid and 3-hydroxypropionic acid in NMR [1 800 (180-12 000) and 50 (0-270) mmol/mol Cr] were higher than the reference values (0-31, 0-35). The median levels of methylmalonic acid and methylmalonic acid in GC/MS [136.56 (43.79-518.67) and 4.87 (1.52-7.52)] were higher than the reference values (0-4 and 0-0.7).Conclusions:NMR and GC/MS technologies are specific for the diagnosis of organic acidemia. The primary component detected by GC/MS is organic acid. NMR technology can break through this limitation and measure the level of various metabolites in urine, which provides a more theoretical basis for the diagnosis and research of inherited metabolic disease.

ABSTRACT

Objective:To evaluate the clinical value of the transcutaneous neuromodulation (TN) in improving gastrointestinal function after gastrointestinal tumor operation.Methods:From April 2019 to June 2020, at The Affiliated People′s Hospital of Ningbo University, 100 patients who underwent gastrointestinal tumor surgery were included. The 100 patients were randomly divided into treatment group(receiving TN treatment, 50 cases)and control group (receiving sham TN treatment, 50 cases). The clinical data of the two groups was compared to evaluate the recovery of gastrointestinal function, which included the time of first defecation, time of first flatus, time of first ambulation, time of resuming diet, the incidence of nausea and vomiting within 3 d after operation and pain score (0 to 10). Heart rate variability (HRV) was compared between two groups to analyze the possible mechanism of TN improving gastrointestinal function after gastrointestinal tumor surgery. Independent sample t test and Chi-square test were used for statistical analysis. Results:Among 100 patients, there were 63 male and 37 female patients, the age was (67.0±11.3) years old, ranged from 28 to 92 years old. Compared with the control group, the time of first defecation, first flatus, first ambulation and resuming diet of treatment group reduced by 31.0%, 39.8%, 38.0% and 32.4% ((72.1±3.0) h vs.(104.5±2.9) h, (49.4±5.7) h vs.(82.1±3.1) h, (3.1±0.7) d vs.(5.0±0.9) d, (4.8±0.9) d vs. (7.1±0.8) d)), respectively; the pain scores on the day 2 and day 3 after operation and incidence of nausea and vomiting within 3 d after operation decreased by 50.0%, 65.5%, 26.0%(1.5±0.6 vs. 3.0±0.7, 1.0±0.6 vs. 2.9±0.6, 16.0%, 8/50 vs. 42.0%, 21/50), respectively, and the differences were statistically significant ( t=54.28, 35.72, 11.67, 13.66, 12.00 and 14.90, χ2=8.21, all P<0.01). The results of HRV analysis showed that the high frequency on day 3 was higher than that on day 1 of treatment group, and the ratio of low frequency to high frequency after operation was lower than that before operation of treatment group (0.5±0.1 vs. 0.4±0.1, 1.2±0.7 vs. 1.9±1.0), and the differences were statistically significant( t=-4.81 and 4.26, both P<0.01), which indicated TN could enhance vagal activity. Conclusions:TN promote the recovery of gastrointestinal function after gastrointestinal tumor operation, and can be used as an adjuvant therapy to accelerate the recovery of gastrointestinal function after gastrointestinal tumor operation.

ABSTRACT

Objective:To investigate Chinese dermatologists′ perceptions of the correlation between diet and psoriasis, and to analyze factors influencing their perceptions.Methods:An exploratory survey study was conducted among Chinese dermatologists via the WeChat and Umer doctor platforms. The questionnaire consisted of 3 sections including career background characteristics (11 items) , dietary suggestions (3 items) and perceptions of effects of diet on psoriasis (19 items) . The results were expressed in frequency, assessed by chi-square test, and variables with significant differences were subjected to binary logistic regression analysis.Results:A total of 3 905 valid questionnaires were received. Among these responders, 91% believed psoriasis could be affected by dietary factors, and most believed certain diets could aggravate the severity of psoriasis; most dermatologists (80.1%) suggested patients avoid some foods or drinks, and the top 5 foods or drinks suggested to be avoided were seafood (2 950, 94.34%) , spicy food (2 599, 83.11%) , wine (2 588, 82.76%) , mutton (1 995, 63.8%) and beef (1 979, 63.29%) . Logistic regression analysis revealed that doctors with a college degree, practitioners of traditional Chinese medicine or integrated traditional Chinese and Western medicine, and those from hospitals of traditional Chinese medicine were more likely to suggest food or drink avoidance (all P < 0.001) ; practitioners of Western medicine ( P < 0.001) and those specializing in psoriasis ( P < 0.001) were more likely to inform that there was no need for food or drink avoidance, while those from municipal or county hospitals were less likely to inform that ( P = 0.025, 0.042, respectively) . Practitioners of traditional Chinese medicine ( P < 0.001) or integrated traditional Chinese and Western medicine ( P = 0.004) were more likely to believe that foods could aggravate the disease condition, while clinicians with working experience of more than 20 years ( P < 0.01) and those with a doctor degree ( P = 0.008) were less likely to think so; doctors with a college degree, and those from traditional Chinese medicine hospitals were more likely to believe that drinks could aggravate the disease condition (both P < 0.05) ; practitioners of traditional Chinese medicine or integrated traditional Chinese and Western medicine, those with intermediate and senior professional titles, those working at psoriasis specialty clinics and those engaged in psoriasis basic research were more likely to believe that foods could relieve the disease condition (all P < 0.05) ; doctors from traditional Chinese medicine hospitals, those with working experience of > 5 years, those with a college degree, and those engaged in psoriasis basic research were more likely to believe that drinks could relieve the condition (all P < 0.05) . Conclusion:A relatively high proportion of Chinese dermatologists had the viewpoints that diets were correlated with the severity of psoriasis and there was a need for food or drink avoidance, and this perception was related to academic degree, practicing category of clinicians, as well as the type and location of the hospital.

ABSTRACT

Objective:To evaluate the role of CXC chemokine receptor 6 (CXCR6)-mediated activation of natural killer T (NKT) cells in renal fibrosis following acute kidney injury (AKI) in mice.Methods:Eighteen male wild-type C57BL/6 mice and 18 CXCR6 knockout C57BL/6 mice, aged 8-10 weeks, weighing 20-30 g, were divided into 6 groups ( n=6 each) using a random number table method: wild-type mouse control group (group WT-CON), CXCR6 knockout mouse control group (group CXCR6 -/--CON), wild-type mouse with AKI group (group WT-AKI), CXCR6 knockout mouse with AKI group (group CXCR6 -/--AKI), wild-type mouse with AKI + NKT cell adoptive transfer group (group WT-AKI-NKT) and CXCR6 knockout mouse with AKI + NKT cell adoptive transfer group (group CXCR6 -/--AKI-NKT). Folic acid 250 mg/kg was intraperitoneally injected to establish the model of renal fibrosis in mice with AKI.NKT cellsuspension 250 μl(1×10 6 cells) was injected through the tail vein on the 4th and 9th days after folic acid injection in group WT-AKI-NKT and group CXCR6 -/--AKI-NKT, respectively.Blood samples were taken from orbital at day 14 after folic acid injection for determination of the concentrations of serum blood urea nitrogen (BUN) and creatinine (Cr). The animals were sacrificed, and renal tissues were obtained for observation of the area of renal fibrosis (by Sirius red staining) and renal injury (using H&E staining) which was scored and for determination of the proportion of CD1d Tetramer+ cells (by flow cytometry), the number of CD206 and α-smooth muscle actin (α-SMA) double positive (CD206 + -α-SMA + ) cells (by immunofluorescence) and expression of interleukin (IL)-4 and IL-13 mRNA (by real-time polymerase chain reaction). Results:Compared with group WT-CON, the BUN and Cr levels, renal injury scores, area of renal fibrosis, proportion of CD1d Tetramer + cells and CD206 + -α-SMA + cell count were significantly increased, and the expression of IL-4 and IL-13 mRNA was up-regulated in group WT-AKI and WT-AKI-NKT ( P<0.05). Compared with group WT-AKI, the BUN and Cr levels, renal injury scores, area of renal fibrosis, proportion of CD1d Tetramer + cells and CD206 + -α-SMA + cell count were significantly increased, and the expression of IL-4 and IL-13 mRNA was up-regulated in group WT-AKI-NKT ( P<0.05), and the BUN and Cr levels, renal injury scores, area of renal fibrosis, proportion of CD1d Tetramer + cells and CD206 + -α-SMA + cell count were significantly decreased, and the expression of IL-4 and IL-13 mRNA was down-regulated in group CXCR6 -/--AKI ( P<0.05). Compared with group CXCR6 -/--CON, the BUN and Cr levels, renal injury scores, area of renal fibrosis, proportion of CD1d Tetramer + cells and CD206 + -α-SMA + cell count were significantly increased in group CXCR6 -/--AKI and group CXCR6 -/--AKI-NKT ( P<0.05). Compared with group CXCR6 -/--AKI, the BUN and Cr levels, renal injury scores, area of renal fibrosis, proportion of CD1d Tetramer + cells and CD206 + -α-SMA + cell count were significantly increased, and the expression of IL-4 and IL-13 mRNA was up-regulated in group CXCR6 -/--AKI-NKT ( P<0.05). Conclusion:CXCR6-mediated activation of NKT cells is involved in renal fibrosis following AKI in mice, and the mechanism may be related to promoting Th2 cytokine-mediated M2 macrophage-myofibroblast transformation.

ABSTRACT

Traumatic rib fractures are the most common injury in thoracic trauma. Previously,the patients with traumatic rib fractures were mostly treated non-surgically,of which 50%,especially those combined with flail chest presented chronic pain or chest wall deformities and over 30% had long-term disabilities,being unable to retain a full-time job. In the past two decades,thanks to the development of internal fixation material technology,the surgical treatment of rib fractures has achieved good outcomes. However,there are still some problems in clinical treatment,including inconsistency in surgical treatment and quality control in medical services. The current consensuses on the management of regional traumatic rib fractures published at home and abroad mainly focus on the guidance of the overall treatment decisions and plans,and relevant clinical guidelines abroad lacks progress in surgical treatment of rib fractures in recent years. Therefore,the Chinese Society of Traumatology affiliated to Chinese Medical Association and Chinese College of Trauma Surgeons affiliated to Chinese Medical Doctor Association,in conjunction with national multidisciplinary experts,formulate the Chinese Consensus for Surgical Treatment of Traumatic Rib Fractures(2021)following the principle of evidence-based medicine,scientific nature and practicality. This expert consensus puts forward some clear,applicable,and graded recommendations from aspects of preoperative imaging evaluation,surgical indications,timing of surgery,surgical methods,rib fracture sites for surgical fixation,internal fixation methods and material selections,treatment of combined injuries in rib fractures,in order to provide references for surgical treatment of traumatic rib fractures.

ABSTRACT

Objective:To examine whether the combination of quantitative regional apparent diffusion coefficient (ADC) and amplitude-integrated electroencephalogram (aEEG) can predict the outcome of comatose patients with severe traumatic brain injury (sTBI).Methods:A prospective study was conducted. The patients with coma caused by sTBI [Glasgow coma scale (GCS) < 8] admitted to Suqian First Hospital from January 2016 to June 2019 were enrolled. All patients underwent aEEG examination and magnetic resonance imaging (MRI) scan within 1 week after emergency treatment. The ADC values of 9 regions of interest (frontal gray matter and white matter, parietal gray matter and white matter, temporal gray matter and white matter, caudate nucleus of basal ganglia, lenticular nucleus and thalamus) were measured by head MRI, and the mean ADC values of frontal lobe, parietal lobe, temporal lobe and basal ganglia were calculated respectively. According to the follow-up results after 12 months, the differences of each index between patients with poor prognosis [Glasgow outcome score (GOS) 1-2] and patients with good prognosis (GOS 3-5) were compared; the receiver operating characteristic curve (ROC curve) was drawn to evaluate the predictive ability of aEEG and ADC for the good prognosis of patients with sTBI, and the predictive value of the combination of aEEG and ADC.Results:A total of 52 patients with sTBI were enrolled, with mean age of (36.7±13.9) years old, 35 of whom were male. Within 12 months follow-up, 29 patients had achieved favorable outcomes and 23 patients had unfavorable outcome. There were 21, 17 and 14 patients with aEEG , and grade, respectively, and 19, 10 and 0 patients had good prognosis respectively. ADC values of 9 regions of interest in patients with good prognosis were significantly higher than those in patients with poor prognosis (×10 -6 mm 2/s: 924±107 vs. 531±87 in frontal gray matter, 804±95 vs. 481±74 in frontal white matter, 831±93 vs. 683±72 in temporal gray matter, 726±87 vs. 654±63 in temporal white matter, 767±79 vs. 690±75 in parietal gray matter, 716±84 vs. 642±62 in parietal white matter, 689±70 vs. 465±68 in caudate nucleus, 723±84 vs. 587±71 in lenticular nucleus, 807±79 vs. 497±67 in thalamus, all P < 0.01). ROC curve analysis showed that the area under ROC curve (AUC) of aEEG for predicting good prognosis of sTBI patients was 0.826, when the cut-off value of aEEG was < 1.5, the sensitivity was 94.7% and the specificity was 72.8%. Among the ADC value prediction abilities in the interested areas, the prediction of ADC value in frontal lobe and basal ganglia area were better than that in sTBI patients. AUC was 0.817 and 0.903 respectively. The best cut-off values were > 726×10 -6 mm 2/s and > 624×10 -6 mm 2/s respectively, the sensitivity of predicting prognosis were both 100%, and the specificity was 63.4% and 61.8%. A model combining frontal ADC and basal ganglia ADC with aEEG was 91.0% sensitive and 93.7% specific for favorable outcome of sTBI patients. Conclusion:Combination of the quantitative measurement of regional ADC and aEEG may be useful for predicting the outcome of the patients with sTBI.

ABSTRACT

The cross-cultural sensitivity scale (ISS) and the self-made cross-cultural communication Traditional Chinese Medicine (TCM) professional ability test were used to investigate the ability of 151 young and middle-aged doctors (under 45 years old) in Xiyuan Hospital of Chinese Academy of Chinese Medicine. SPSS 21.0 was used to describe the statistics of the questionnaire data. ANOVA was used to analyze the factors that affected the capability, and Pearson to analyze the relevance of the internal structure of this capability. The final score of the test was 3.73±0.54 points (5 points in total). The capability of spreading TCM of young and middle-aged doctors had a significant positive correlation with their individual professional background, English language proficiency, and oversea experience ( P<0.05). The result showed that the correlation among 5 dimensions of cross-cultural sensitivity was significant, and there was a significant correlation between cross-cultural sensitivity and professional competence to spread TCM ( r>0.5, P<0.01). The young and middle-aged doctors in this hospital had an overall high score in this survey, and it was necessary to improve interaction enjoyment and strengthen professional English training. When selecting relevant talents, it should be noted that those with educational background of TCM and integrated TCM and western medicine were more suitable as workers to spread TCM. Educational background, English ability, and relevant experience showed a significant impact on capability to spread TCM. It was recommended to carry out quantitative testing of the capability to spread TCM of young and middle-aged doctors widely. When selecting talents for cross-cultural spreading of TCM, attention should be paid on factors that related to the capability.
