Objective To investigate the strengths and weaknesses of SPAIR and WE in iShim-IVIM of breast gland MRI scanning. Methods Twenty patients with breast tumor underwent iShim-IVIM and DCE-MRI scanning by SPAIR and WE technology. SNR ,CNR and ADC of the SPAIR-iShim and WE-iShim imaging were cal-culated and imaging quality were evaluated. Statistical analysis was done afterwards. Results The SNR and CNR of WE technology is higher than those of SPAIR statistically (P<0.05). There is no significant statistical differ-ence in score of the images between SPAIR and WE(P>0.05). The ADC of the center of the tumor has no signifi-cant statistical difference between SPAIR and WE(P>0.05). Conclusion The quality of the images using WE is significantly improved than SPAIR ,but both of them can meet the diagnostic requirements ,and the ADC has no statistical difference as well.

Objective:To investigate the efficacy of octreotide combined with thrombin in the treatment of upper gastrointestinal bleeding in schistosomiasis cirrhotic patients.Methods:Using prospective design, from January 2017 to January 2019, 86 patients with upper gastrointestinal bleeding caused by schistosomiasis cirrhosis in Binzhou People's Hospital were selected as subjects, aged 34 - 62 years. According to the random number table method, they were divided into control group ( n = 43) and observation group ( n = 43). In two groups, the patients were given 20 U of pituitrin (with a drip rate of 0.4 U/min), after 24 h of treatment, it was changed to a half-dose maintenance, and was stopped after 24 h of bleeding control; 0.1 mg octreotide was used for intravenous injection, continuous intravenous pumping at a rate of 25 μg/h, and continued to pump 2 to 3 days after controlling bleeding. On this basis, the patients in the observation group were perfused with 10 U/ml thrombin. It was implemented once at an interval of 4 hours for 3 days. The clinical efficacy, hemostasis and adverse reactions were compared between the two groups. At the same time, the blood flow of portal vein and splenic vein and liver function indexes [total bilirubin (TBil), glutamic pyruvic transaminase (ALT), glutamic oxaloacetic transaminase (AST)] were compared between the two groups after 3 days of treatment. Results:The total effective rate in the observation group (93.02%, 40/43) was significantly higher than that in the control group (76.74%, 33/43, P < 0.05). The hemostatic time, blood transfusion volume and rebleeding rate in the observation group [(19.25 ± 3.28) h, (214.58 ± 42.45) ml, 6.98% (3/43)] were significantly lower than those in the control group [(27.47 ± 3.93) h, (394.66 ± 67.52) ml, 27.91% (12/43), P <0.05]. After 3 days of treatment, the blood flow of portal vein and splenic vein in the observation group [(276.68 ± 54.36), (552.49 ± 67.83) ml/min] were significantly lower than those in the control group [(307.52 ± 59.67), (598.53 ± 73.28) ml/min, P < 0.05]. After 3 days of treatment, the levels of serum TBil, AST and ALT in the observation group [(42.96 ± 8.44) μmol/L, (36.47 ± 6.53) U/L, (31.74 ± 6.39) U/L] were significantly lower than those in the control group [(73.36 ± 9.67) μmol/L, (54.25 ± 8.74) U/L, (50.28 ± 9.26) U/L, P < 0.05]. The total incidence of adverse reactions in the observation group (16.28%, 7/43) was significantly lower than that in the control group (37.21%, 16/43, P < 0.05). Conclusions:Octreotide combined with thrombin is effective in the treatment of upper gastrointestinal bleeding caused by schistosomiasis cirrhosis. It can effectively control bleeding, improve portal vein and splenic vein blood flow and liver function, and has high safety, so it is worthy of clinical promotion.

Objective:To investigate the correlation between thyroid function index and serum visfatin in patients with acute pancreatitis (AP).Methods:Using a prospective design, 65 patients with AP treated in Binzhou People's Hospital from December 2017 to December 2019 were selected as the research subjects. They were divided into mild acute pancreatitis (MAP) group ( n = 35) and severe acute pancreatitis (SAP) group ( n = 30) according to the acute physiology and chronic health Ⅱ (APACHE Ⅱ) score ( < 8, ≥8 scores). At the same time, 40 healthy people were selected as the control group. The serum levels of free thyroxine (FT 4), free triiodothyronine (FT 3) and thyrotropin (TSH) were measured by chemiluminescence immunoassay. Radioimmunoassay was used to measure serum reverse triiodothyronine (rT 3) level, and enzyme-linked immunosorbent assay was used to measure serum visfatin level. Pearson method was used to analyze the correlation between thyroid function index and serum visfatin in patients with AP. Results:The FT 4 [(14.02 ± 3.63), (15.68 ± 3.05) pmol/L], FT 3 [(2.34 ± 0.80), (3.66 ± 0.65) pmol/L], and TSH levels [(2.78 ± 0.85), (3.10 ± 0.57) mU/L] in SAP and MAP groups were significantly lower than those in control group [(17.03 ± 3.96), (6.04 ± 1.55) pmol/L, (4.88 ± 2.30) mU/L, P < 0.05], but the rT 3 levels [(1.63 ± 1.12), (1.23 ± 0.26) nmol/L] were significantly higher than that in control group [(0.97 ± 0.28) nmol/L, P < 0.05]. There was significant difference in serum FT 3 levels between SAP and MAP groups ( P < 0.05). The serum visfatin levels of SAP, MAP and control groups were (10.75 ± 2.92), (3.70 ± 1.73), (2.30 ± 1.31) ng/ml, the difference between the three groups was statistically significant ( F = 67.174, P < 0.05). The serum visfatin levels in SAP and MAP groups were higher than that in control group, and that in SAP group was higher than that in MAP group ( P < 0.05). There were negative correlations between serum FT 3 level and visfatin level in SAP and MAP groups ( r = - 0.672, - 0.610, P < 0.05). Conclusions:The serum visfatin level and thyroid function index of AP patients are abnormal. The levels of FT 3 and visfatin are correlated with the severity of AP patients, and there is a negative correlation between the levels of FT 3 and visfatin. Detection of thyroid function index is helpful to judge the AP patient's condition.

Objective To investigate the effect of tooth extraction with antibiotics on atherosclerosis, and to examine the expression of serum interleukin 6(IL-6) and the pathological changes of the carotid artery in chronic periodontitis(CP) rats with or without atherosclerosis(As).Methods A total of 44 SD rats were randomly divided into four groups, group A(normal control), group B(As), group C(CP),group D(CP+As).After model establishment, group C and group D were randomly divided into group C1/D1 (tooth extraction) and group C2/D2(tooth extraction with antibiotics) according to random number table and received the corresponding oral intervention treatment respectively.Serum IL-6 levels were determined by enzyme linked immunosorbent assay(ELISA) respectively one week before the intervention, one week after the first intervention, one, three, five weeks after the second intervention.The pathological changes of the carotid artery were accessed under light microscope.Results At all sampling time points, the levels of serum IL-6 in group B, C, D were higher than that of group A, with group D 1 being increased most obviously,significantly higher than that of group A(P＜ 0.001).One week after the second intervention, the content of IL-6 in group C and group D peaked[C1(127.0±29.9) ng/L, C2: (120.6±23.1) ng/L, D1: (175.1±50.8) ng/L,D2: (160.5±37.7) ng/L], and was significantly higher than that of group B[B: (43.4±7.5) ng/L, P＜0.001].Then they all had varying degrees of decline, 5 weeks after the second intervention, group C1 and D1 were still higher than that of group B, but group C2 and D2 were lower than that of group B.At all sampling time points, the levels of serum IL-6 in group C2/D2 were lower than those in group C1/D1, 5 weeks after the second intervention the difference was most obvious and statistically significant(P＜0.001).Pathology showed that the carotid artery wall in group A was normal.The carotid artery wall was thickened in group B,inflammatory cells and foam cells could be seen, and elastic fibers disordered.The carotid artery wall in group C 1 was uneven, foam cells and a small amount of inflammatory cells were visible, and elastic fiber disordered.Obvious thickening was not seen in the carotid artery wall of group C2, a small amount of foam cells and inflammatory cells were found, and elastic fiber mildly disordered.The carotid artery wall in group D1 was obviously uneven, calcium salt deposits were visible in the artery wall, a large amount of inflammatory cells and foam cells could be found, and elastic fiber disordered.Obvious thickening was not seen in the carotid artery wall of group D2, a small amount of inflammatory cells and a large amount of foam cells could be seen, and elastic fiber disordered.Conclusions Periodontitis and hyperlipidemia could increase the level of serum IL-6 and the risk of the As.In chronic periodontitis rats with or without atherosclerosis, when periodontal inflammation was not controlled, tooth extraction may increase the risk of the As.At the time of tooth extraction, giving the anti-inflammatory treatment can reduce the risk to a certain extent.

Objective To investigate the clinical application of skin bridge preopening window drainage in enhanced recovery of mixed hemorrhoids surgically treated with external dissection and internal ligation.Methods A total of 620 patients with mixed hemorrhoids surgically treated with external dissection and internal ligation were retrospectively analyzed from March 1,2021-February 28,2022.Patients were divided into the observation group(n=304)and the control group(n=316)according to the single and even numbers randomly generated at the time of admission.In the observation group,on the basis of conventional operation and drug treatment in the control group,most of them chose to implement preopening window drainage of the skin bridge according to the intraoperative evaluation of the anal skin bridge according to the unified evaluation criteria.Symptom-sign scoring scale used to evaluate the anal edema and pain after the operation.To compare and analyze differences in anal edema,anal pain and the postoperative hospital stay between the observation group and the control.Results The average daily edema scores of the observation group and the control group were 0.56 and 1.2 points,respectively.The average daily edema score of the observation group was lower than that of the control group,with the statistically significant differences(P＜0.05).The average daily pain scores of the observation group and the control group were 0.6 and 1.201+0.289 points,respectively.The average daily pain score of the observation group was lower than that of the control group,with the statistically significant differences(P＜0.05).The average hospitalization days of the observation group and the control group were 8 days and 10 days,respectively.The average length of stay in the observation group was less than that in the control group,with the statistically significant differences(P＜0.05).Conclusion Skin bridge preopening window drainage can effectively relieve the degree of anal edema and pain in patients with mixed hemorrhoids surgically treated with external dissection and internal ligation,improve clinical efficacy,shorten the postoperative hospital stay.It has practical value and clinical significance for enhanced recovery.

Objective:To evaluate the mid-term complication rates of the Hui-Jing one-stage procedure (lingual mucosa combined with longitudinal preputial island flap onlay urethroplasty + tubularized incised plate glansplasty)versus the classic Bracka staged surgery for children with severe hypospadias.Methods:A retrospective analysis was conducted on clinical data of 75 children with proximal hypospadias who were treated at the Seventh Medical Center of PLA General Hospital from March 2017 to June 2022. Of these patients, 31 cases (15 cases penoscrotal type and 16 cases perineal type) were underwent the Bracka two-stage surgery with a median age of 38 months (24.0, 44.5) and 44 cases underwent the Hui-Jing one-stage procedure (23 cases penoscrotal type and 21 perineal type) with a median age of 40.5 months (20.75, 90.5). The length of urethral plate defect after correction of penile curvature was (4.30±0.84)cm in the Bracka group and (4.56±0.79)cm in the Hui-Jing group, which also showed no significant difference.There was no statistically significant difference of the median age and the position of preoperative urethral opening between the two groups( P=0.47, P=0.74). The first stage of Bracka repair consists of orthoplasty and urethral bed substitution with free preputial graft. After 6 months, the urethral plate created from free graft was tabularized to form neourethra; Hui-Jing procedure group used the free lingual mucosal as urethral plate substitution, then we conducted longitudinal preputial island flap Onlay and Snodgrass phalloplasty. The incidence of postoperative urethral fistula, urethral stricture and urethral diverticulum was compared between the two groups of cases and the difference in efficacy between the two procedures was assessed. Results:Among the 75 patients included in the study, there was no statistically significant difference in age or location of urethral meatus between the Bracka and Hui-Jing groups. In Bracka group, 9 cases of urethral stricture (29.0%), 6 case of urethral fistula (19.4%), and 2 cases of urethral diverticulum (6.5%) occurred after surgery, while 12 cases of urethral fistula (27.3%) and 3 case of urethral fistula (6.8%) occurred in the Hui-Jing group. No urethral stricture occurred in Hui-Jing group. There was no statistically significant difference in overall incidence of complications between the two groups [17/31(54.8%) vs.15/44(34.1%), P=0.12]. The incidence of urethral fistula and urethral diverticulum show no significant differences between two groups(19.4% vs 27.3, P=0.61, 6.5% vs. 6.8%, P=0.13). The number of operation in Bracka group was (2.68±1.03) and the hospitalization cost was (12 984.63±3 808.15) Yuan, while the number of operation in Hui-Jing group was (1.36±0.53) and the hospitalization cost was (8 490.54±3 136.84) Yuan. Conclusions:The Hui-Jing one-stage procedure can be used for the surgical treatment of children with severe hypospadias. There is no urethral stricture happened in Hui-Jing group, while the general complication incidence and incidence of urethral fistula and diverticulum show no differences.

Objective:To analyze the relationship between stress hyperglycemia (SHG) and the prognosis of acute myocardial infarction (AMI) without diabetes mellitus (DM).Methods:Using a retrospective cohort study method, 396 AMI patients without DM or impaired glucose tolerance (IGT) and admitted glycated hemoglobin A 1c (HbA 1c)≤6.0% from January 2018 to December 2020 in Xuanwu Hospital, Capital Medical University were selected. Among them, 238 patients did not have SHG at admission (group A), 85 patients had SHG at admission but their blood glucose level did not reach the diagnostic criteria for DM (group B), and 73 patients had SHG at admission and their blood glucose level reached the diagnostic criteria for DM (group C). The baseline data and the incidence of main adverse cardiovascular and cerebrovascular events (MACCE) were recorded. Multivariate Cox regression was used to analyze the independent risk factors of MACCE after discharge in AMI patients without DM. Results:The incidence of MACCE after discharge in group B and group C was significantly higher than that in group A: 29.4% (25/85) and 35.6% (26/73) vs. 18.5% (44/238), the incidence in group C was significantly higher than that in group B, and there was statistical difference ( P<0.05). Multivariate Cox regression analysis result showed that SHG on admission was an independent risk factor for MACCE after discharge in AMI patients without DM ( P<0.05), and LVEF on admission was an independent protective factor for MACCE after discharge in AMI patients without DM ( P<0.01). Conclusions:SHG on admission is the independent risk factor of MACCE in AMI patient without DM. Early detection, assessment and proper intervention measures based on clinical reality should be advocated for the AMI patients with SHG to further improve the prognosis.

Objective:To explore the regulatory effects of long non-coding RNA H19(LncRNA H19)on the osteogenic differentia-tion of MC3T3-E1 cells under the stimulation of advanced glycation end products(AGEs).Methods:MC3T3-E1 cells were cultured under the stimulation of 10 μg/mL AGEs.The cells were observed by alkaline phosphatase(ALP)staining after 7 d and alizarin red staining after 21 d culture respectively.Cell transfection technology was used to overexpress LncRNA H19 in the cells,RT-qPCR was used to detect the mRNA expression levels of ALP,Runx-2,OCN,SP7 before and after transfection of LncRNA H19.Western blotting was used to detect the protein expression of Runx-2 and[3-catenin in the cells.Results:Under the stimulation of AGEs,the ALP stai-ning color of MC3T3-E1 cells became lighter,the formation of calcified nodules was reduced,the mRNA expression levels of ALP,Runx-2,OCN,SP7 and LncRNA H19 were decreased(P＜0.05),and the protein expression level of Runx-2 was decreased.After transfection of LncRNA H19(lv-H19),the mRNA expression of LncRNA H19 was significantly up-regulated(P＜0.05),the mRNA expression of ALP,Runx-2,OCN and SP7 genes was increased(P＜0.05),ALP staining was deeper,and the expression of β-catenin was increased.Conclusion:Under the stimulation of AGEs,LncRNA H19 may affect the osteogenic differentiation of MC3T3-E1 cells by activating the expression of WNT/[3-catenin.
