Objective:To investigate the current situation of coping styles in Crohn's disease patients and its related influencing factors.Methods:A total of 80 patients with Crohn's disease admitted to our hospital from Apri 2021 to Dec 2022 were selected to evaluate their coping styles with a simple coping style questionnaire,and relevant data were collected.The factors affecting the coping styles of Crohn's disease were analyzed by multivariable logistic regression.Results:Among the 80 patients,29 cases were negative coping,the incidence was 36.25% .There were 51 patients with positive coping(63.75% ).Educational level,simplified Crohn's disease activity index(CDAI)score,adverse psychology,social support and type D personality were associated with negative coping(P＜0.05).Gender,age,family history,working status,monthly family income,place of residence,and marital status were not associated with negative coping in patients with Crohn's disease(P＞0.05).Multivariable logistic regression analysis showed that education level of high school or below(OR=2.945,95% CI:1.139-7.614),higher CDAI score(OR=11.999,95% CI:4.387-32.815),poor psychology(OR=5.950,95% CI:2.180-16.239),low social support(OR=3.598,95% CI:1.370-9.448)and type D personality(OR=3.208,95% CI:1.118-8.904)were risk factors for negative coping in patients with Crohn's disease(P＜0.05).Conclusions:The incidence of negative coping in patients with Crohn's disease is higher,which is related to high school education or below,high CDAI score,poor psychology,low social support,and type D personality.Therefore,clinical measures can be taken to promote patients to actively cope with the disease.

ObjectiveTo investigate the clinical efficacy and safety of Qihuang Jianpi Zishen granules in the treatment of cardiac involvement in systemic lupus erythematosus （SLE）. MethodA total of 62 SLE patients with cardiac involvement treated in the Department of Rheumatology and Immunology， the First Affiliated Hospital of Anhui University of Chinese Medicine from June 2021 to December 2022 were randomized into control and observation groups （n=31）. The control group was treated with methylprednisolone tablets and hydroxychloroquine sulfate tablets， and the observation group with Qihuang Jianpi Zishen granules on the basis of the therapy in the control group. After 12 weeks of treatment， the two groups were compared in terms of the therapeutic effect， cardiac function indicators ［left atrial end-diastolic diameter （LADd）， left ventricular end-diastolic diameter （LVDd）， left ventricular posterior wall thickness （LVPWTd）， peak blood flow velocity in early diastolic period （peak E）， peak blood flow velocity in late diastolic period （peak A）， E/A ratio， stroke volume （SV）， left ventricular ejection fraction （LVEF）， left ventricular short axis shortening rate （LVFS）， and B-type natriuretic peptide （BNP）］， vascular damage indicators ［nitric oxide （NO）， endothelin-1 （ET-1）， vascular endothelial growth factor （VEGF）， and homocysteine （Hcy）］， inflammation indicators ［erythrocyte sedimentation rate （ESR） and hypersensitive C-reactive protein （Hs-CRP）］， anti-double-stranded DNA （dsDNA） antibodies， disease activity index （SLEDAI） score， mitigation of symptoms and signs， and occurrence of adverse reactions. ResultThe total response rate in the observation group was 87.09%， which was higher than that （67.74%） in the control group （P<0.01）， and the incidence of adverse reactions had no significant difference between the two groups. After treatment， the control group showed lowered LVDd， LVPWTd， BNP， ET-1， VEGF， and Hcy （P<0.05） and increased E peak， E/A ratio， SV， LVEF， and LVFS （P<0.05）. In the observation group， LADd， LVDd， LVPWTd， peak A， BNP， NO， ET-1， VEGF， and Hcy decreased （P<0.05）， while peak E， E/A ratio， SV， LVEF and LVFS increased （P<0.05） after treatment. The treatment in both groups decreased the scores of palpitation， chest tightness， dyspnea， and edema （P<0.05）， reduced ESR， Hs-CRP， ds-DNA， and SLEDAI （P<0.05）. After treatment， the observation group had lower LADd， LVDd， LVPWTd， peak A， BNP， and scores of palpation， chest tightness， dyspnea， and edema （P<0.05） and higher peak E， E/A ratio， SV， LVEF， and LVFS （P<0.05） than the control group. In addition， the observation group had lower NO， ET-1， VEGF， Hcy， ESR， Hs-CRP， ds-DNA， and SLEDAI than the control group （P<0.05）. ConclusionQihuang Jianpi Zishen granules combined with hydroxychloroquine sulfate and methylprednisolone can improve multiple indicators and mitigate the symptoms and signs of SLE patients with cardiac involvement， demonstrating a clinical application value.

Purpose To investigate the clinicopathological characteristics,diagnosis,and differential diagnosis of invasive mucinous adenocarcinoma(IMA)and mixed invasive mucinous and non-mucinous adenocarcinoma(mIMA).Methods The clinical data were collected in 36 patients with primary IMA and 17 patients with mIMA,and the expression of TTF-1,CK7,CK20,SATB2,CDX2,EGFR,HNF4a,etc.was detected by immunohistochemical EnVision two-step method.The Sanger se-quencing and the FISH were used for KRAS mutation and NRG1 gene rearrangement detection.The clinicopathological character-istics were analyzed with review of relevant literature.Results There were 9 cases(25.0％)and 3(8.3％)cases of papillary and micropapillary structures in IMA,while 13 cases(76.5％)(P＜0.001)and 9 cases(52.9％)(P=0.001)were present in mIMA.There were 5 cases(13.9％)of high nuclear grade of IMA and 10 cases(58.8％)of high nuclear grade of mIMA(P=0.002).TTF-1 had a positive rate of 37.5％in IMA,but 60.0％and 80.0％in the mucinous adenocarcinoma and non-mucinous adenocarcinoma components of mIMA(P=0.021),respectively.The positive rates of CK7,CK20,and CDX2 in IMA were 90.6％,21.9％,and 9.4％,and the positive rates in mucinous adenocarcinoma and non-mucinous adenocarcinoma components of mIMA were 100％,20％,20％and 100％,6.7％,6.7％,respectively and no SATB2 expression was found in all cases.There was no significant difference in the expres-sion of total EGFR and two EGFR mutation-specific antibodies(L858R,DEL19)between IMA and mIMA.There were 3 cases of mucinous adenocarcinoma with L858R positive in mIMA,and 2 of them were negative for non-mueinous adenocarcinoma.In another case,the non-mueinous adenocarcinoma component of mIMA expressed DEL19,but the mucinous adenocarcinoma component was not expressed.The positive rate of HNF4a in IMA was 72.0％(18/25),and those of HNF4a in mucinous adenocarcinoma and non-mucinous adenocarcinoma in mIMA were 41.7％(5/12)and 33.3％(4/12),respectively(P=0.048).KRAS gene sequencing was carried out in 19 cases of IMA,among which 9 cases(47.4％)had mutations,G12D and G12V were most commonly detected,and 4 cases of mIMA were sequenced,but none of them showed KRAS mutations.FISH detection showed that 2 cases(7.1％)IMAs had NRG1 translocation rearrangement.Conclusion Pulmonary mIMA is more aggressive than IMA.For example,mIMA has significantly more papillary structure,micropapillary structure,and high nu-clear grade cases than IMA.The differences in immunohisto-chemical expression and KRAS mutation between the two are sta-tistically significant.

Objective:To investigate the molecular mechanism of sorafenib against hepatocellular carcinoma.Methods:Sorafenib efficacy was screened and verified by the hepatocellular carcinoma patient-derived tumor xenograft (PDX) model. Veterinary B-mode ultrasonography and in vivo confocal laser scanning microscopy were used to observe PDX angiogenesis. Immunohistochemistry was used to observe the expression of proliferation and angiogenesis-related proteins in PDX tissue. Real-time quantitative PCR technology was used to observe the RUNX3 gene in PDX tissues. SPSS 17.0 statistical software was used for statistical analysis.Results:Four cases of PDX were used to screen the efficacy of sorafenib. PDX1 had a significant response to sorafenib, with an inhibition rate of 68.07%. Compared with the control group, sorafenib had significantly inhibited PDX1 relative tumor volume (5.76±2.14 vs. 11.71±2.87, P<0.05). Cell division index (39.50±7.72 vs. 67.10±9.14, P<0.05) and Ki67 expression (288.6±43.40 vs. 531.70±55.60, P<0.05) were significantly decreased. Veterinary B-mode ultrasonography showed evident blood flow signals in PDX1 tumors. In vivo confocal laser scanning microscopy results showed that sorafenib had significantly reduced the total vessel length (1573.00±236.21 vs. 2675.03±162.00, P<0.05) and area (11 145.33±1931.97 vs. 20 105.37±885.93, P<0.05)) of PDX1 tumors. Immunohistochemical results showed that sorafenib had significantly down-regulated the protein expressions of CD34 (27.55±3.76 vs. 45.47±5.57, P<0.05), VEGF (16.33±2.86 vs. 22.77±3.20, P<0.05) and MVD (38.75±6.01 vs. 55.50±8.61, P<0.05). Real-time PCR results showed that sorafenib had significantly up-regulated RUNX3 gene expression (2.14±0.71 vs. 1.00±0.36, P<0.05). However, there was a negative correlation between the expression of RUNX3 gene and the ratio of VEGF-positive cells in sorafenib group ( R2=0.509 7). Conclusion:Sorafenib may inhibit the PDX angiogenesis and the growth of hepatocellular carcinoma by regulating the RUNX3-VEGF pathway.

Objective: To probe into the mechanism and interventional effects of silybin-phospholipid complex on amiodarone-induced steatosis in mice. Methods: Eight-week-old male C57BL/6 mice were divided into three groups (5 mice in each group): a control group (WT) with normal diet, a model group with amiodarone 150mg/kg/d by oral gavage (AM), and an intervention group on amiodarone 150mg/kg/d combined with silybin-phospholipid complex(AM+SILIPHOS. All mice were fed their assigned diet for one week. Then, one week later, serum alanine aminotransferase, aspartate aminotransferase, triglyceride, total cholesterol and high-density lipoprotein were detected of each group. A liver pathological change was observed by oil red O and H&E staining. Ultrastructural pathological changes of hepatocytes were observed to evaluate the intervention effect by transmission electron microscopy. RT-q PCR was used to detect the expression of peroxisome proliferator-activated receptor alpha and its regulated lipid metabolism genes CPTI, CPTII, Acot1, Acot2, ACOX, Cyp4a10 and Cyp4a14 in liver tissues. Intra-group comparison was done by paired t-test. One-way ANOVA was used for comparison between groups and semi-quantitative data were tested using Mann-Whitney U test. Results: Oil Red O and H&E staining results of liver tissue in the intervention group showed that intrahepatic steatosis was significantly reduced when compared to model group. Transmission electron microscopy showed that the model group had pyknotic nuclei, mitochondrial swelling, structural damage, and lysosomal degradation whereas the intervention group had hepatic nucleus without pyknosis, reduced mitochondrial swelling and slight structural damage than that of model group. RT-q PCR results showed that the expression of peroxisome proliferator-activated receptor alpha, CPTI, CPTII, Acot1, Acot2, ACOX, Cyp4a10 and Cyp4a14 were increased in the model group but the expression of CPTI, Cyp4a14, Acot1 and peroxisome proliferator-activated receptor alpha were decreased in the intervention group (P < 0.05). Conclusion Silybin-phospholipid complex can alleviate amiodarone-induced steatosis, and its mechanism may play a role in protecting mitochondrial function and regulating fatty acid metabolism. Thus, silybin-phospholipid complex has potential intervention effect on amiodarone-induced fatty liver.

Objective To study the effect of nursing intervention on the catheter prolapse of the powerpPICC (high pressure injection type PICC catheter). Methods A total of 140 patients with powerpPICC were divided into observation group and control group by the catheter inserting time, with 70 cases in each group. The observation group received conventional nursing care, and the control group the targeted care measures based on analysis of catheter prolapse in the observation group. Result The rate of catheter prolapse in the observation group was significantly higher than that of the control group (P<0.05). Conclusions The prolapse of powerpPICC is related to catheter material, exposed length, fixed method, patient's compliance, catheter caring method. The care measures based on the different causes can decrease the rate of catheter prolapse and extend its duration.

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.

Objective To explore any changes in the surface electromyography (sEMG) signals measured on the spastic upper limb muscles of stroke parents during maximum isometric voluntary contraction and to analyze any abnormal synergy patterns quantitatively in order to design better rehabilitation programs for developing coordination.Methods Ten stroke survivors with hemiparesis were selected into a patient group and ten healthy counterparts were recruited into a control group.sEMG signals were recorded bilaterally from the flexor carpi ulnaris (FCU),biceps brachii (BB),triceps brachii (TB) and deltoid (D) during maximum isometric voluntary contractions involving wrist flexion and extension,elbow flexion and extension,and shoulder abduction.The two groups' co-contraction ratios (CR) and co-activation ratios were calculated and compared.Results During elbow flexion and extension the average CR of the BB on the affected side was significantly higher than that on the unaffected side and also significantly higher than the control group average.The average CR of the TB on the affected side was significantly higher than that of the healthy controls.In all cases the average CR of the BB was larger than that of the TB.The difference in CR between the TB and the BB on the affected side was significantly larger than on the unaffected side and the control group average.During elbow flexion,the co-activation ratio of the FCU,TB and D on the affected side was significantly higher than on the unaffected side and among the healthy controls,and the co-activation ratio of the FCU on the affected side was significantly higher than that of the D and TB.During elbow extension,the co-activation ratio of the FCU,BB and D on the affected side was significantly higher in the same way,and the co-activation ratio of the FCU on the affected side was again significantly higher than that of the D and BB.During wrist flexion,the average co-activation ratio of the BB and D on the affected side was significantly greater than that on the unaffected side and among the healthy controls,and the co-activation ratio of the BB on the affected side was significantly higher than that of the D and TB.During shoulder abduction,the co-activation ratio of the BB on the affected side was significantly larger than on the unaffected side and among the healthy controls.Conclusion After a stroke the upper limbs often show flexor spasticity and abnormal synergy patterns.Rehabilitation strategy should be adopted to tackle these so as to enhance overall limb coordination.
