ABSTRACT
Objective:To explore the effect of case-based learning (CBL) combined with mind mapping on pathophysiology teaching.Methods:Totally 124 undergraduate students from Batch 2017 of Yanjing Medical College of Capital Medical University were selected as research subjects, and they were divided into experimental group ( n=60) and control group ( n=64). The traditional teaching method was used in the control group, while the experimental group adopted CBL combined with mind mapping teaching method. At the end of the course, the teaching effectiveness was evaluated by the usual grades from Mosoteach online teaching platform and test performances. SPSS 17.0 was used to perform Wilcoxon rank sum test and the Welch's correction t test. Results:The initiative of students in the experimental group was significantly improved than that in the control group ( P<0.001), and the understanding ability was also better in the experimental group than the control group ( P=0.020). The average theoretical scores of the experimental group were significantly better than those of the control group ( P=0.036), with the main manifestations that the scores of objective questions were higher than those of the control group ( P<0.001), and the scores of short answer and discussion questions were higher than those of the control group ( P=0.006). There was no significant difference in noun interpretation scores between the two groups ( P=0.302). Conclusion:The CBL combined with mind mapping can significantly improve the teaching quality of pathophysiology.
ABSTRACT
Breastcancerin females, which is consideredthe most dreadfuldisease in India andthe worldas compared toother gynaecological cancers,demands extensive care and proper medicationin order to control itsprogressive growth. In addition to the conventional care ofthe patients, Complementary andAlternative Medicine(CAM)is administeredin a controlled way through proper guidance and counselling in orderto attainimprovedphysical andmental health forthe patients.Objective: The aim of the study wasto assess the effectiveness of CAMcomprehensive nursing interventionsand their benefit forpatients who havebreast cancer and gynaecological tumours.Methods: Statistical data was used to map the adult womendiagnosed with breast and gynaecological cancer and who were set to start new chemotherapy treatments. A total of 450 patients from different states of East India were enrolled in the studyover a period of four years. The patients wereselectedbased on their preference for undergoing CAM.The research was conducted usingacross-sectionalanonymous self-administered questionnaireto examine women's perspectivestowards the use of CAM and itseffect on their mental andphysical health.Results:42%of the women preferred theuseofCAM astheir alternative treatment. Breast cancer patients disclosed that 48.1% of them had used CAM and 39% of women with gynaecological cancersstated that they had usedCAM. The results further indicated a less frequent deteriorationin the health of CAM users(38.4%) thantonon-users(55%). In terms of those who utilizedvitamins and nutritional diets,60% of the participants reported using a proper diet, including antioxidants, minerals, vitamins and herbs etc. 37% opted for spiritual healing through yoga, 26% utilized energy healing, 42.4% utilized acupuncture,72% preferred massagesand 23% of patients utilized chiropractic methods.The use of CAM was foundmainlyin the patients with proper education and awareness and those with a family history of cancer who were not receiving the necessary care from their previous primary physician.Conclusion:CAM still requiresextensive research in terms of its applications in dealing with patients and in orderto successfully launch programmes aimed at promoting its useworldwide andto eradicate all the other false notions about it.[Ethiop.

Under the National Cancer Registry Program,the breast, cervix, uteri,and oral cavity(7)are the most common cancer sitesin women. According to statistics, 50-60% of all cancers amongIndian women are commonly found inthe cervix uteri, breast, corpus uteri and ovaries,which are the main organs forcancer invasion. The percentage of women who experience these types of cancer is increases, with more women becoming susceptible to breast cancer, in women up to 3-8% suffer fromovarian cancer,0.5-4.8%have cancer of the corpus uteri, 1-3% have vulva and/or gestational trophoblastic tumours and a staggering75,000 or more women have breast cancer. With the advancements of the disease through time,research programs were also improved in order to enable the improvement of existing measures and/or the development of new measures aimed at combating the diseas and decreasing mortality rates. Apart from the conventional chemotherapy technique,various other programs have been introduced andencorporated into treatment regimes in order to improve the lives of those who are affected by cancer.Complementary andAlternative Medicine (CAM) emphasizesthe methods and practices that are therapeutic and which help diagnose or curethe disease,these methods are intended tocomplement the conventional methods and can be used in place of mainstream medicine. Women with breast cancer and other gynaecological tumoursare increasingly inclined towards the use of CAM. With the increasing number of cancer reports in Indiaand the world,and with the principal amount leading to mortality, women with proper education and awareness are inclined to choosealternative methods rather than the old conventional ones. The side-effects resulting from the chemotherapy are immense and toxic,which is one of the reasons women are inclined to choose.Various research projects and cumulative studies have been conducted in order to review and discoverthe

Mechanosensitive ion channels (MSCs) are key molecules in the mechano-electrical transduction of arterial baroreceptors. Among them, acid-sensing ion channel 2 (ASIC2) and transient receptor potential vanilloid subfamily member 1 (TRPV1) have been studied extensively and documented to play important roles. In this study, experiments using aortic arch–aortic nerve preparations isolated from rats revealed that both ASIC2 and TRPV1 are functionally necessary, as blocking either abrogated nearly all pressure-dependent neural discharge. However, whether ASIC2 and TRPV1 work in coordination remained unclear. So we carried out cell-attached patch-clamp recordings in HEK293T cells co-expressing ASIC2 and TRPV1 and found that inhibition of ASIC2 completely blocked stretch-activated currents while inhibition of TRPV1 only partially blocked these currents. Immunofluorescence staining of aortic arch–aortic adventitia from rats showed that ASIC2 and TRPV1 are co-localized in the aortic nerve endings, and co-immunoprecipitation assays confirmed that the two proteins form a compact complex in HEK293T cells and in baroreceptors. Moreover, protein modeling analysis, exogenous co-immunoprecipitation assays, and biotin pull-down assays indicated that ASIC2 and TRPV1 interact directly. In summary, our research suggests that ASIC2 and TRPV1 form a compact complex and function synergistically in the mechano-electrical transduction of arterial baroreceptors. The model of synergism between MSCs may have important biological significance beyond ASIC2 and TRPV1.
ABSTRACT
Objective:To investigate the characteristics and influencing factors of esophageal stenosis after endoscopic submucosal dissection (ESD) for early esophageal carcinoma.Methods:Patients who underwent ESD in the Digestive Endoscopy Center of the Second Affiliated Hospital of Army Medical University from January 2011 to December 2018 were included. The data were obtained from medical records and follow-up. The influencing factors of stenosis were determined by single factor and Cox regression analysis.Results:A total of 654 patients underwent ESD and 79 (12.1%) of them developed postoperative esophageal stenosis. The median time of stenosis development was 27 (17, 43) days. The morphology and lesion circumferential proportion were independent factors for the occurrence of stenosis after ESD. The stenosis incidence of type Ⅱa was 6.601 times (95% CI: 1.518-28.709, P=0.012) compared with that of type Ⅱc. The incidence of stenosis in lesions with 75%-<100% and 100% circumference was 17.408 times (95% CI: 8.009-37.839, P<0.001)and 52.439 times (95% CI: 23.905-115.029, P<0.001) respectively compared with that of patients <75%. Among the 79 patients, 27 had severe stenosis, and the lesion circumferential proportion was an independent factor for stenosis. Compared with the group of lesion circumferential proportion of less than 75%, the incidences of stenosis of lesion circumferential proportion of 75%-<100% and 100% were 7.775 (95% CI: 1.977-30.577, P=0.003) and 70.062 (95% CI: 19.879-246.926, P<0.001) times respectively. Conclusion:The morphology and lesion circumferential proportion are two independent factors for the occurrence of esophageal stenosis after ESD. Additionally, lesion circumferential proportion is an independent factor for the occurrence of severe esophageal stenosis after ESD.
ABSTRACT
Objective:To compare the clinical effects of two enteral nutritional emulsions, TP-HE and TPF, in elderly patients with severe pneumonia.Methods:This was a randomized study with contemporaneous controls.A total of 56 elderly patients over 65 years old who met the diagnostic criteria for severe pneumonia and were receiving insulin were enrolled.They were randomly divided into the observation group(n=28, enteral TPF-HE at a uniform rate through a nasogastric tube)and the control group(n=28 cases, enteral TPF at a uniform rate through a nasogastric tube). The total daily energy supply was calculates based on the ideal weights of patients.Prealbumin(PA), serum albumin(ALB), body mass index(BMI)and hemoglobin(Hb)were continuously measured at 1, 2, 3, 4, 5, 6 and 7 days after treatment.The effects of the enteral nutritional emulsions in elderly patients with severe pneumonia were analyzed by using repeated measures analysis of variance in a general linear model.Results:There was no significant difference in PA(244.5±55.1)mg/L vs.(237.8±40.4)mg/L, ALB(37.6±5.6)mg/L vs.(38.3±5.5)mg/L, BMI(21.9±0.2)kg/m 2vs.(22.4±0.2)kg/m 2)or Hb(104.4±26.8)mg/L vs.(103.6±25.6)mg/L between the TP-HE group and the TPF group before admission( P>0.05). The energy received from the enteral nutritional emulsions was not significantly different between the TP-HE group and the TPF group(79.8±4.8)kcal/d vs.(79.3±6.6)kcal/d( P>0.05). PA and serum ALB levels had significant differences between the TP-HE group and the TPF group at 1, 2, 3, 4, 5, 6 and 7 days after treatment( P<0.01 or 0.05). Increases in PA and serum ALB levels varied at certain time points between the TP-HE group and the TPF group.Hb levels had no significant difference at 1 and 2 days( P>0.05), but were significantly different at other time points between the two groups( P<0.01). There was no significant difference in BMI between the two groups( F=1.709, P>0.05). Conclusions:Both of the enteral nutrition emulsions can improve PA, ALB and Hb levels, with TP-HE offering more significant effects on PA, ALB and Hb levels.There is no difference in BMI at any time point whether patients receive TP-HE or TPF.
ABSTRACT
Objective:To explore the differential diagnosis of pancreatic acinar cell carcinoma (PACC) and pancreatic ductal adenocarcinoma (PDAC) based on multidetector computed tomography (MDCT) features.Methods:The clinical, pathological and MDCT imaging data of 26 patients with pathologically confirmed PACC and 145 patients with pathologically confirmed PDAC who underwent MDCT from November 2013 to April 2021 were retrospectively studied. The differences of MDCT features including tumor location, tumor size, common pancreatic duct and bile duct dilatation, pancreatitis, lymph node metastasis, cyst, pancreatic parenchyma atrophy, duodenal involvement, bile ductal and vascular involvement between the two groups were compared. Univariate analysis and multivariate analysis by logistic regression models were performed to identify the independent predictive factors for PACC.Results:The tumor size, bile duct dilatation, lymph node metastasis, pancreatic parenchyma atrophy and vascular involvement were significantly different between PACC group and PDAC group (all P value<0.05). Multivariate analysis revealed that the tumor size ( OR=1.07, 95% CI 1.028-1.15, P=0.001), lymph node metastasis ( OR=0.23, 95% CI 0.065-0.800, P=0.02), pancreatic parenchyma atrophy ( OR=0.15, 95% CI 0.048-0.490, P=0.002) were closely associated with PACC. Conclusions:The tumor size, bile duct dilatation, lymph node metastasis, pancreatic parenchyma atrophy and vascular involvement evaluated by MDCT had a certain value in differentiating PACC from PDAC, and the tumor size, lymph node metastasis and pancreatic parenchyma atrophy were independent predictors for the diagnosis of PACC.
ABSTRACT
Objective:To accurately identify the relationship between the arterial radiomics score (rad-score) and pathologic superior mesenteric vein (SMV) resection margin in patients with pancreatic head cancer.Methods:The clinical data of 181 patients with pathologically confirmed pancreatic head cancer, who underwent multi-slice computed tomography (MDCT) within one month of resection in the First Affiliated Hospital of Naval Medical University between January 2016 and December 2018 were collected. Based on the pathology of SMV resection margin, the patients were divided into SMV negative margin group ( n=127) and SMV positive margin group ( n=54). The clinical, pathological and radiological features were compared between two groups. 3D slicer software was used to draw the region of interest in each layer of the primary CT arterial images for tumor segmentation. Rython package was applied to extract the radiomics features of pancreatic tumors after segmentation and the extracted features were reduced and chosen using the least absolute shrinkage and selection operator (Lasso) logistic regression algorithm. Lasso logistic regression formula was applied to calculated the arterial rad-score. Univariate and multivariate logistic regression models were used to analyze the association between the arterial rad-score and SMV resection margin. ROC was drawn and AUC, sensitivity, specificity and accuracy for diagnosing the SMV resection margin were calculated. The clinical usefulness of arterial rad-score for diagnosing SMV resection margin was determined by decision curve analysis (DCA). Results:There were statistical differences on LVSI and the touching angle of tumor and SMV/portal vein (PV) between SMV negative margin group and SMV positive margin group (all P<0.001). A total of 1 029 arterial radiomics CT features were obtained, and 14-selected arterial phase features associated with SMV resection margin were determined after being reduced by the Lasso logistic regression algorithm. Univariate analysis showed that the arterial radiomics score, LVSI, the touching angle of tumor and SMV/PV were all correlated with SMV resection margin (all P<0.001). Multivariate analyses confirmed that patients with high arterial radiomics score had a 3.63-fold risk of positive resection margin compared with that with low arterial radiomics score, and a higher arterial rad-score was associated with a higher risk of SMV positive resection margin ( P<0.0001). At the cut-off value of -0.711, AUC of the arterial rad-score for diagnosing SMV resection margin was 0.838, and the sensitivity, specificity and accuracy was 77.8%, 75.6% and 76.24%. Decision curve analysis demonstrated that the percentage of the arterial radiomics score for predicting the positive SMV resection margin was >0.02, and the application of the arterial radiomics score could benefit the patients. Conclusions:The arterial rad-score was strongly correlated with SMV resection margin of pancreatic cancer, and can accurately predict SMV resection margin and provide a new tool for preoperative noninvasive evaluation of the SMV resection margin.

Objective@#To examine whether the long-term resting heart rate (RHR) pattern can predict the risk of cardiovascular and cerebrovascular diseases (CVDs).@*Methods@#This prospective cohort study included 63 040 participants who took part in the health examination in 2006 and one of the health examinations on 2008 or 2010 and were free of myocardial infarction, stroke, arrhythmia, cancer and not treated with β-recepter blocker. The outcomes were the first occurrence of myocardial infarction and stroke during the follow up ended on December 31, 2015. RHRs were measured in 2006, 2008, and 2010. We used latent mixture modeling SAS Proc procedure to identify RHR trajectories. We identified 4 distinct RHR trajectory patterns based on the data derived from 2006 and on the pattern change during 2006 to 2010 (low-stable, moderate-stable, moderate-increasing, elevated-decreasing). Collected the general clinical data of the patients. Cox regression model was used to determine the association between RHR trajectory patterns and the risk of CVDs during follow up. Hazard ratio (HR) with 95% confidence intervals (CI) were calculated using Cox regression modeling.@*Results@#There were statistical significance among the 4 distinct RHR trajectory patterns on the following variables: age, gender, smoking status, drinking status, physical activity, education status, history of use antihypertensive drugs, history of hypertension,history of diabetes, body mass index, triglycerides, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, fasting blood glucose, and the level of high-sensitivity C-reactive protein (all P<0.01). The moderate-increasing pattern experienced the highest risk of developing stroke and CVDs among all 4 patterns. The cumulative incidence of cerebral infarction, cerebral hemorrhage and CVDs in the order of low-stable trajectory, moderate-stable trajectory and moderate-increasing trajectory. The cumulative incidences of cerebral infarction, cerebral hemorrhage and CVDs in elevated-decreasing trajectory group were significantly lower than those in moderate-increasing trajectory group, but higher than those in moderate-stable trajectory group. Compared to the low-stable pattern, adjusted HR was 1.3 (95%CI 1.0-1.6) for the moderate-increasing pattern after adjustment for potential confounders.@*Conclusion@#Our study finds that individuals with moderate-increasing RHR trajectory pattern are associated with higher risk of cardiovascular and CVDs.
ABSTRACT
PURPOSE: Obstructive sleep apnea and chronic obstructive pulmonary disease are independent risk factors of cardiovascular disease (CVD), and their coexistence is known as overlap syndrome (OS). Endothelial dysfunction is the initial stage of CVD; however, underlying mechanisms linking OS and CVD are not well understood. The aim of this study was to explore whether OS can lead to more severe inflammation and endothelial apoptosis by promoting endothelial dysfunction, and to assess the intervention effects of antioxidant tempol. MATERIALS AND METHODS: Male Wistar rats (n=66) were exposed to normal oxygen [normal control (NC) group], intermittent hypoxia (IH group), cigarette smoke (CH group), as well as cigarette smoke and IH (OS group). Tempol intervention was assessed in OS group treated with tempol (OST group) or NaCl (OSN group). After an 8-week challenge, lung tissues, serum, and fresh blood were harvested for analysis of endothelial markers and apoptosis. RESULTS: The levels of intracellular adhesion molecule-1, vascular cellular adhesion molecule-1, and apoptosis in circulating epithelial cells were the highest in OS group and the lowest in NC group. These levels were all greater in IH group than in CH group, and were lower in OST group than in OS and OSN groups (all p < 0.001). CONCLUSION: Synergistic effects of IH with cigarette smoke-induced emphysema produce a greater inflammatory status and endothelial apoptosis. OS-related inflammation and endothelial cell apoptosis may play important roles in promoting cardiovascular dysfunction, and antioxidant tempol could achieve a partial protective effect.

ABSTRACT
Objective To guide clinicians to strengthen tumor screening in patients with acute cerebral infarction by analyzing the clinical manifestation,laboratory examinations and imaging features of patients with acute cerebral infarction as the first manifestation of occult malignant tumors. Methods From January 2013 to January 2015,1139 patients with acute cerebral infarction admitted to the Department of Neurology,Peking University Third Hospital were collected. Eight of them (0. 7% )were found to have somatic malignancy during hospitalization. The clinical manifestations,risk factors,imaging changes,Ddimer levels and other laboratory results and prognosis were reviewed,and the related literature was reviewed and discussed. Results Eight patients with cerebral infarction as the first manifestation of malignant tumor,their ages were 58 -78 (70 ±3)years old,6 were males,2 were female. Five of them were lung cancer. Intrahepatic cholangiocarcinoma,colon cancer and prostate cancer were in 1 case respectively. Three patients who had multiple cerebral infarctions died of respiratory failure during hospitalization,and the intervals between diagnosis and death were 49,95 and 28 d,respectively. Five patients improved the Ddimer test,including 2 of them had elevated levels of D-dimer (0. 73 μg/ L and 3. 0 μg/ L respectively);in 8 patients with improved creatine kinase isoenzyme MB (CK-MB)test,the CK-MB levels were elevated in 2 patients (31 U/ L and 49 U/ L respectively),and one of the patients was diagnosed as acute myocardial infarction. All the patients improved head magnetic resonance imaging (MRI)diffusion-weighted imaging (DWI)and cerebral vascular examination,and only one patient with cerebral infarction was consistent with the stenotic vessels. Six patients had bilateral cerebral hemisphere infarctions,and multiple cerebral infarction occurred in the anterior and posterior circulation simultaneously,and MRI-DWI indicated that the cerebral infarction lesions were numerous small or large area cerebral infarctions in multiple vessels. Conclusion In patients with multiple cerebral infarction with unknown etiology,especially those with early recurrent stroke,attention should be paid to the possibility of somatic malignancy,and the early recurrence of acute cerebral infarction suggests poor prognosis.

Objective To compare faster rehabilitation of different surgical approaches in total hip arthroplasty (THA)patients using a direct anterior approach or posterolateral approach.Methods Sixty-eight patients (35 in direct anterior THA and 33 in posterolateral THA) from September 2015 to March 2016 were recruited in the present study.The incision length,operation duration,intraoperative blood loss,serum creatinekinase (CK),C-reactive protein (CRP),erythrocyte sedimentation rate (ESR),interleukin-6 (IL-6) and visual analogue scale (VAS) pain score were compared between two groups respectively.The Harris hip score,the University of California at Los Angeles (UCLA) pain,walking,and activity scores,postoperative hospital length of stays,gait analysis,component placement and complications were also compared.Results The mean incision length,operation duration,intraoperative blood loss were 11.23±0.97 cm,73.77±9.20 min and 157.15±35.83 ml in the DAA group respectively,while those in PLA group were 15.16±1.12 cm,64.12±13.31 min and 126.97±45.45 ml.The mean incision length of the DAA group were significantly less than that of the PLA group.The DAA group underwent longer operation time that associated with more intraoperative blood loss.The levels of CK and inflammation markers were increased in the PLA group compared with those in the DAA group.The VAS pain score was less in the DAA group than the PLA group within postoperative 72 hours.Functional recovery in the DAA group was faster than that in the PLA group based on the Harris hip score,UCLA scores,and gait analysis up to 3 months.There was no difference in these outcomes between the groups beyond 6 months.The average postoperative hospital length of stay was 2.95±0.24 days and 3.35±0.51 days for the DAA group and PLA group respectively.The patients in DAA group required less postoperative hospital length of stays.The angle of acetabular cup anteversion in the DAA group (16.4°±2.3°) was lesser than that in the PLA group (20.4°±2.8°).There was one intraoperative nondisplaced greater trochanter fracture in the DAA group,whereas no intraoperative complications were occurred in the PLA group.Conclusion The present study showed that using direct anterior approach in THA provided significant benefits for patients in terms of muscle damage,VAS score,hospital length of stays and functional recovery in the early stage postoperatively compared to using posterolateral approach.
ABSTRACT
Objective Nontraumatic convexity subarachnoid hemorrhage (cSAH) complicating acute ischemic stroke is rare.Here we report four cases and review the relevant literature.Methods All cSAH cases at Peking University Third Hospital between January 2010 and December 2014 were collected and those associated with acute cerebral infarction were identified.Clinical medical records,neuroimaging data,treatment and prognosis were retrospectively reviewed.Results We found four cSAH patients with co-existing acute cerebral infarction.Two had ipsilateral middle cerebral artery (MCA) stenosis,one had ipsilateral internal carotid artery (ICA) stenosis,and the fourth case did not present significant cerebrovascular stenosis on magnetic resonance angiogram but had atrial fibrillation.All patients underwent brain magnetic resonance imaging (MRI) and none showed signs of cerebral amyloid angiopathy.One patient took oral Plaix because of the progression of ischemic stroke and the other three did not receive oral antiplatelet medications Three patients who were followed up for one to three years remained in stable condition.Conclusions Patients with cSAH complicated by ischemic stroke usually have a good prognosis.Most patients show significant atherosclerotic stenosis of ipsilateral vessels.MRI and assessment of extracranial and intracranial cerebral vessels for cSAH patients are recommended.
ABSTRACT
Objective To investigate the impact of different kinds of laparoscopic surgery including conventional blunt elimination and modified acute elimination on sex hormone, antral follicle count and ovarian volume of patients with endometriosis (EMs). Methods 100 patients with EMs were chosen from January 2013 to April 2016 and randomly divided into control group (50 patients) with conventional blunt elimination and observation group (50 patients) with modified acute elimination; and the thickness of elimination lesion, the removal rate of ovary cortex, the thickness of ovarian cortex, the level of serum sex hormones, the AFC number of affected side and the volume of ovary before and after operation of the two groups were compared. Results There was no significant difference in the thickness of lesion elimination, the removal rate and removed thickness of ovarian cortical between the two groups (P > 0.05). The thickness of lesion elimination and the thickness of ovarian cortex in middle position of observation group were significantly lower than that in control group (P 0.05). There was no significant difference in the levels of AFC number of affected side before and after treatment (P > 0.05). The levels of AFC number of affected side in hilus ovarii of control group after treatment were significantly lower than that before treatment (P < 0.05). The volume of ovary of both groups after treatment were significantly lower than that before treatment (P < 0.05). The volume of ovary of observation group after treatment were significantly higher than that in control group (P < 0.05). Conclusion Compared with conventional blunt elimination, modified acute elimination in the treatment of patients with EMs can efficiently shorten the operation time, reduce the surgical trauma degree, speed up the recovery process after operation, regulate the level of FSH and AMH and be helpful to protect the ovarian reserve function.
