Objective To explore the correlationships between microperfusion diffusion indexes derived from intravoxel incoherent motion(IVIM)and perfusion values measured by arterial spin labeling (ASL)in renal allograft. Methods A total of 76 renal allograft recipients and 26 age-matched volunteers (group 0)were included in this prospective study. All subjects were underwent conventional MRI, IVIM and ASL MRI which were performed in the oblique-sagittal plane. Seventy-six recipients were divided into two groups based on the estimated glomerular filtration rate(eGFR):recipients with good allograft function(group 1, eGFR≥ 60 ml · min-1 · 1.73m-2,n=44)and recipients with impaired allograft function(group 2, eGFR<60 ml · min-1 · 1.73m-2,n=32). Three IVIM indexes values, including true diffusion coefficient(ADCslow), pseudo-diffusion coef fi cient(ADCfast), perfusion fraction(PF), and one ASL index value of renal cortex(renal blood flow, RBF)were measured. One-way analysis of variance and the least significant difference were used to compare the different of each cortical index values among three groups. Correlations between the ADCslow, ADCfast, PF, RBF and eGFR as well as the correlation among the indexes were evaluated using Pearson correlation coefficients. Results For cortical ADCslow, ADCfast, PF and RBF values, allografts with good function and impaired function showed significantly differences compared healthy controls(all P<0.01). In allografts with good function, cortical ADCslow,ADCfast,PF showed no significantly differences compared with controls(all P>0.05), but RBF value was significantly lower(P<0.05). The ADCslow, ADCfast, PF and RBF values of renal cortex were significantly lower in allografts with impaired function compared to allografts with good function(all P<0.01). In renal allografts, there were significant positive correlations between cortical ADCslow, ADCfast, PF, RBF value and eGFR(r values were 0.604, 0.552, 0.579 and 0.673, all P<0.01). Cortical ADCfast and PF value exhibited a significant correlation with RBF for recipients(r values were 0.501 and 0.423, all P<0.01). Conclusion Cortical ADCfast and PF values derived from IVIM and RBF measured by ASL show a significant positive correlation in renal allografts.

From December 2019, Coronavirus disease 2019 (COVID-19) pneumonia (formerly known as the 2019 novel Coronavirus [2019-nCoV]) broke out in Wuhan, China. In this study, we present serial CT findings in a 40-year-old female patient with COVID-19 pneumonia who presented with the symptoms of fever, chest tightness, and fatigue. She was diagnosed with COVID-19 infection confirmed by real-time reverse-transcriptase-polymerase chain reaction. CT showed rapidly progressing peripheral consolidations and ground-glass opacities in both lungs. After treatment, the lesions were shown to be almost absorbed leaving the fibrous lesions.

Objective To investigate the effect of omeprazole on plasma concentration, efficacy and adverse reactions of capecitabine in patients with colon cancer. Methods Seventy?two patients with colon cancer treated with capecitabine were analysed retrospective. The patients treated with capecitabine combined with omeprazole were identified as experimental group and the capecitabine treatment alone as control group. The differences of blood concentration and the side effects of capecitabine between these two groups were compared. Results The plasma concentration of 5?Fluorouracilum in experimental group was ( 126.25 ± 50.59) μg／ml, without significant difference of (123.09±56.70) μg／ml in control group (P＝0.121). The incidence of Ⅲ to Ⅳ degree bone marrow suppression, nausea, vomiting, diarrhea and hand?foot syndrome in experimental group were 13.8%, 0%, 0% and 19.4%, respectively. In control group, the incidence ofⅢto Ⅳdegree bone marrow suppression, nausea, vomiting, diarrhea and the hand?foot syndrome were 11.1%, 0%, 0% and 19.4%, respectively, without significant difference of experimental group ( P＞0.05). The incidence of acid reflux and heartburn in the control group was 72.2%, significantly higher than 44.4% of the experimental group ( P＜0.05). The objective response rate ( ORR) and progression?free survival time (PFS) in these two groups were 30.6% and 33.3%, and 8.0 month and 8.5 month, respectively, without significant difference (P＞0.05). Conclusion The intravenous omeprazole attenuates reflux and heartburn of colon cancer patients treated with capecitabine, without affecting its plasma concentration and side effects and has no impact on the PFS of these patients.

Chronic subdural hematoma (cSDH) occurs in acute subdural hemorrhage after head trauma or converts from effusion. Traditional treatment is based on conservative treatment and surgical drainage. The effective rate of conservative treatment is only 3%-18%; even with drilling drainage treatment, the recurrence rate is as high as 33%. Recently, the middle meningeal artery embolization technique based on pathological analysis can greatly reduce the recurrence rate, and the operation is simple and curative effect is exact. This article reviews the pathogenesis of cSDH and progress of interventional therapy.

Objective:To explore the mental health level of Chinese adults aged 20~79 years and its association with exercise based on the surveillance data.Methods:A cross-sectional study was conducted in a total of 161 901 samples from the Fifth National Physical Fitness Surveillance, including 121 928 adults aged 20-59 years and 39 973 elderly aged 60-79 years. The mental health status was assessed by a comprehensive questionnaire, and the participation in frequency and duration of exercise were investigated. Chi-square test and Logistic regression were applied to test the relationship between exercise and mental health using SPSS 26.0 software.Results:The rate of depressive symptoms among residents aged 20-79 years in China was 16.6%(26 311/158 518). In the adults aged 20-59 years, the rates of depression and anxiety symptoms were 18.0%(21 465/119 409) and 13.8%(16 435/119 444), respectively, and the proportion of those who often or always felt stressed was 15.3%(18 373/120 444). In the elderly aged 60-79 years, the rate of depression symptoms was 12.4%(4 846/39 109), the proportion of those with loneliness scale scores higher than 25 was 32.8%(12 650/38 525), and 4.0%(1 587/39 395) elderly often or always felt stressed. Compared with the non-exercisers, the risk of depression symptoms in the exercisers was reduced by 20% ( β=-0.22, OR=0.80, 95% CI: 0.78-0.82). With increased frequency and intensity of physical exercise, the mental health condition improved significantly. For those who exercised at least 3 days a week and had moderate intensity or above, the detection rate of depression symptoms decreased by 35% ( β=-0.39, OR=0.65, 95% CI: 0.63-0.67).The negative associations between exercise and depression were found in different ages, genders and resident subgroups. The risk of anxiety was 6% lower in the adults who participated in physical activity ( β=-0.06, OR=0.94, 95% CI: 0.91-0.97) and 15% lower in those who exercised over 3 days per week at moderate-to-vigorous intensity ( β=-0.16, OR=0.85, 95% CI: 0.81-0.89). No association between exercise and risk of stress was observed ( P>0.05), but the positive effect was also found as exercise frequency and intensity increased. Older adults with exercise had a reduced risk of high loneliness scores by 50% ( β=-0.70, OR=0.50, 95% CI: 0.47-0.52) and a 35% lower detection of stress risk ( β=-0.43, OR=0.65, 95% CI: 0.59-0.72). Conclusion:Exercise was significantly and meaningfully associated with self-reported mental health.Exercise can actively and effectively prevent and improve mental health.

BACKGROUND:Kidney deficiency and blood stasis syndrome are common traditional Chinese medicine syndromes observed in knee osteoarthritis,which serve as fundamental pathogenesis factors.There exists a significant connection between the two.Previous studies have demonstrated that kidney deficiency and blood stasis syndrome effectively contribute to knee joint cartilage degeneration and the progression of knee osteoarthritis.However,the mechanisms underlying the promotion of knee joint cartilage damage remain unclear and require further investigation. OBJECTIVE:To investigate the influence of kidney deficiency and blood stasis syndrome on the progression of knee osteoarthritis in Sprague-Dawley rats. METHODS:Sixteen Sprague-Dawley rats were randomly divided into two groups:a model observation group and a control group,with eight rats in each group.Animal models of kidney deficiency were induced by ovary removal in the model observation group,while the control group was given a sham procedure for ovarian removal.Two months after modeling,both groups underwent modified HULTH surgery to induce knee osteoarthritis.One week after modified HULTH surgery,the model observation group was subcutaneously given adrenaline hydrochloride to make blood stasis models,while the control group was subcutaneously given normal saline.At the 5th week after modified HULTH surgery,blood rheology,coagulation parameters,triiodothyronine,tetraiodothyronine,and estradiol levels were measured.Knee joint X-ray images were taken,and knee joint sections were stained with safranin O-fast green,hematoxylin-eosin,and immunohistochemistry. RESULTS AND CONCLUSION:Compared with the control group,the model observation group exhibited significant increases in whole blood viscosity at low,medium,and high shear rates,as well as increased plasma viscosity.Fibronectin levels in the coagulation parameters were significantly increased,while prothrombin time and activated partial thromboplastin time were significantly decreased.Triiodothyronine,tetraiodothyronine,and estradiol levels were all significantly decreased.Radiographic results showed that the model observation group exhibited more severe degree of knee joint space narrowing and surface roughness,with the appearance of high-density shadows.Hematoxylin-eosin and safranin O-fast green staining demonstrated more severe cartilage damage in the model observation group,with significantly higher OARSI and Mankin scores compared with the control group.Compared with the control group,immunohistochemistry results showed a significant reduction in the expression of extracellular matrix type II collagen and aggrecan protein in the cartilage of the model observation group rats.Moreover,there was a significant increase in the expression of matrix metalloproteinase 13 and aggrecanase 5,which are inflammatory factors.These results indicate that the Sprague-Dawley rat model of knee osteoarthritis with kidney deficiency and blood stasis was successfully established.Kidney deficiency and blood stasis syndrome further aggravate cartilage extracellular matrix degradation and cartilage degeneration by promoting the expression of inflammatory factors,thereby promoting the progression of knee osteoarthritis in rats.
