Objective To explore the value of abnormal imaging findings on susceptibility weighted imaging (SWI) in delayed graft function (DGF). Methods The conventional MRI and SWI images of 26 cases with DGF and 20 cases with normal renal function of transplanted kidneys were retrospectively analyzed. Patients with cysts and angiomyolipomas were excluded. Normal structures of transplanted kidney were identified. If lesions of abnormal signal intensity were found in the transplanted kidney, the location, border and signal intensity compared to renal cortex would be analyzed. The differences in signal intensity between the abnormal signal lesions and normal renal cortex in the same SWI layer of DGF were compared by using independent-sample t test. The differences in positive detection rate of discovering the abnormal signal lesions in DGF between conventional MRI and SWI were compared by using McNemar test. Results Of the 26 cases with DGF, one case was found to exhibit abnormally low signal lesions with fuzzy boundary located at junctional zone between cortex and medulla on both conventional MRI and SWI images. Ten cases were found to exhibit abnormally low signal lesions with fuzzy boundary located at junctional zone between cortex and medulla on SWI images only. Fifteen cases exhibited no abnormal signal lesions on both conventional MRI and SWI images. Twenty cases with normal renal function of transplanted kidney, no abnormal signal lesions were found on both conventional MRI and SWI images. The differences in signal intensity between the abnormally low signal lesions (130±20) and normal renal cortex (177±25) in the same SWI layer of 11 cases with DGF were statistically significant (t=-4.582,P<0.01). The differences in positive detection rate of discovering the abnormally low signal lesions in DGF between conventional MRI [3.8%(1/26)] and SWI [42.3% (11/26)] were statistically significant (χ2=8.100,P=0.002). Conclusions Abnormally low signal lesions with fuzzy boundary located at junctional zone between cortex and medulla on SWI images suggest the presence of DGF. Compared with conventional MRI, SWI appears to be superior in detecting the abnormally low signal lesions.

Perioperative neurocognitive disorder(PND)significantly threatens brain health,leading to prolonged hospitalization,increased patient mortality risk,and poor long-term prognosis.Sleep disorder may substantially elevate the risk of neurocognitive dysfunction.However,the specific role of sleep in PND development remains to be elucidated.In addition,controversy exists over whether interventions for perioperative sleep disorder can effectively prevent PND.Therefore,this review aims to explore the basic function and regulatory principles of sleep,the clinical characteristics of perioperative sleep disorder,its role and potential mechanisms in PND development.Furthermore,we also provide new evidence on the potential therapeutic strategies to modulate sleep disorder for PND management,to improve patient's neurocognitive prognosis and long-term outcomes.

Objective To analyze the disease burden caused by occupational coal workers' pneumoconiosis (CWP) in Anhui Methods Province. A total of 1 649 patients with occupational CWP diagnosed in Anhui Province from 1950 to 2019 were selected as the study subjects using a retrospective study method. Age, gender, survival time, location, working age of disease onset, age of death, stage and date of diagnosis of CWP, comorbidities at the time of investigation, hospitalization and outpatient expenses in the past year, cost of absence from work, cost of absence from work of caregivers, and cost of nutrition and transportation were investigated. The years of life lost, years lived with disability (YLDs), disability adjusted life years (DALYs) Results and economic losses were calculated. Among these patients, 1 405 cases survived and 244 cases died. In the age range - - - of 20.0 70.0 years, the YLDs of surviving patients were 2.12 22.20 (8.19±3.59) person years. The YLDs of patients with disease vs - P complications was higher than that of patients without complications [(8.55±3.95) (7.87±3.21) person years, <0.01]. The total - - DALYs of the patients was 14 031.59 person years, and the average per capita DALYs was 8.51 person years. Its YLDs accounted for 82.0 % of the total DALYs. The total economic loss caused by CWP in the 1 405 surviving patients was 354.903 0 Conclusion million yuan, and the average per capita economic loss was 252 600 yuan. The disease burden caused by CWP is relatively high in Anhui Province. In addition to early detection, diagnosis and treatment, it is necessary to focus on prevention and treatment of CWP complications to reduce the disease burden.

Objective:To explore the effect of total hip arthroplasty via modified direct anterior approach on hip function, balance function and gait parameters in patients undergoing primary total hip arthroplasty.Methods:Eighty-nine patients who underwent total hip arthroplasty for the first time in Anqing First People′s Hospital of Anhui Medical University from January 2020 to December 2021 were selected as the study subjects by prospective study, and they were divided into the observation group (modified direct anterior approach total hip arthroplasty, 45 cases) and the control group [direct anterior approach (DAA) total hip arthroplasty, 44 cases] according to the random number table method. Perioperative indexes of the two groups were observed and complications were counted, and hip function, balance function, gait parameters and follow-up imaging data were compared between the two groups at 1 year after postoperative follow-up.Results:After treatment, the anal exhaust time, hospital stay, blood loss, ambulation time and postoperative feeding time in observation group were shorter or less than those in control group:(9.15 ± 1.33) h vs. (10.89 ± 1.53) h, (5.07 ± 2.21) d vs. (7.04 ± 2.23) d, (53.48 ± 12.43) ml vs. (64.44 ± 12.53) ml, (4.07 ± 0.21) d vs. (6.15 ± 1.24) d, (0.47 ± 0.13) d vs. (0.75 ± 0.24) d, P<0.05.

At 1-month follow-up after surgery, there were no statistical differences in acetabular cup anteversion angle, abduction angle, femoral stem peripheral zona pellucida score, and lower limb lebgth between the two groups ( P>0.05). Conclusions:Modified direct anterior approach total hip arthroplasty can promote postoperative recovery, improve hip function, enhance balance function, reduce risk of complications, and improve gait parameters.

OBJECTIVETo investigate the effect of catenin p120 (p120ctn) translocation on the malignant features of hepatocellular carcinoma and its interrelation with beta-catenin in E-cadherin-mediated cell signaling.

METHODSExpression and translocation of p120ctn, tyrosine phosphorylation, and its binding capacity to E-cadherin were detected by DNA transfection, immunoblotting and immunoprecipitation. Cellular localization of p120ctn and beta-catenin was detected by immunofluorescent microscopy. Cell adhesion, cell migration and cell proliferation were also studied.

RESULTSExpression of p120ctn increased after cells transfected with p120ctn isoform 3A, and it was located mainly at cell-cell contact region. Its binding to E-cadherin was enhanced. After EGF stimulation, tyrosine phosphorylation of p120ctn was increased, membrane expression of p120ctn and beta-catenin was decreased while cytosol expression was increased. It was translocated into the nucleus, cell adhesiveness was increased but mobility decreased. With over-expression of p120ctn, beta-catenin was recruited by nucleus export. Cell proliferation was reduced but it was increased after EGF treatment.

CONCLUSIONp120tn plays an important role in cell adhesion, migration and proliferation of hepatocellular carcinoma, and its tyrosine phosphorylation might contribute to this mechanism. There might be a competitive relationship between p120ctn and beta-catenin.

OBJECTIVETo observe early intervention effects of Modified Shuyu Pill (MSP) on vascular cognitive impairment no dementia (VCIND).

METHODSTotally 100 patients VCIND were randomly assigned to the treatment group (43 cases) and the control group (33 cases). On the basis of the treatment targeting risk factors of blood vessels, patients in the treatment group were treated by MSP, while those in the control group were treated by donepezil hydrochloride. The therapeutic course was 16 weeks. The neuropsychological scales [mini-mental state examination (MMSE) and Montreal cognitive assessment (MOCA) score] and Chinese medicine dementia syndromes scales were observed before and after treatment.

RESULTSThe MMSE and MOCA score of the two groups increased when compared with the same group before treatment (P < 0.01). But there was no statistical difference in MMSE or MOCA score after treatment between the two groups (P > 0.05). The Chinese medicine dementia syndromes scales significantly decreased in the treatment group when compared with before treatment (P < 0.01). But there was no statistical difference in Chinese medicine dementia syndromes scales in the control group between before and after treatment (P > 0.05). There was statistical difference in Chinese medicine dementia syndromes scales after treatment between the two groups (P < 0.01).

CONCLUSIONMSP could effectively intervene the progress of VCIND.
