Objective To investigate the clinical value of echo-tracking(ET) technique in evaluating the carotid elasticity in patients with hyperuricemia and hyperuricemia combined with hyperlipidemia.Methods One hundred and twenty patients with hyperuricemia were divided into two group:group of hyperuricemia (group A) and group of hyperuricemia combined with hyperlipidemia (group B).Sixty normal persons were served as the control group.ET was used to measure the carotid artery elastic modulus including stiffness parameters (β),pressure-strain elastic modulus (Ep),arterial compliance (AC),augmentation index (AI) and pulse wave conducting velocity (PWVβ).Then the statistical data were analyzed to observe the changes of each parameter.Results In the comparison of three groups,elastic function index β,Ep,PWVβ and AI in group A and group B were higher than those of control group (P ＜0.05) ;however,AC was lower than that of control group (P ＜ 0.05).Compared with group A,elastic function index β,Ep,PWVβ,AI was higher in group B,while the AC was lower than that of group B (P ＜0.05).Conclusions ET may be helpful to prevent atherosclerotic changes and to provide the basis for the clinical diagonosis and treatment atherosclerotic changes.

Objective To evaluate the clinical value of multi-tomographic imaging mode of three-dimensional ultrasound combined with surface imaging in diagnosing and staging bladder tumors.Methods Seventy-five patients were examined with three-dimensional ultrasound and two-dimensional ultrasound.In addition,54 cases were undergone preoperative multislice spiral CT.All cases were proved by pathology after operation.Results The qualitation accuracy in the diagnosis of bladder tumor with two-dimensional ultrasound was 93.3%(70/75) and that of three-dimensional ultrasound was 98.7%(74/75).The staging accuracy rates with two-dimensional ultrasound and three-dimensional ultrasound were 83.5%(106/127) and 93.2%(123/132) respectively.The difference of bladder tumor staging between three-dimensional ultrasound and two-dimensional ultrasound was significant (P＜0.05).The qualitation accuracy in the diagnosis of bladder tumor with CT was 90.7%(49/54).The preoperative staging rate of CT was 79.7%(59/74),compared with that of three-dimensional ultrasound,the difference was significant(P＜0.05).Conclusions Multi-tomographic imaging mode of three-dimensional ultrasound combined with surface imaging can provide useful information and makes an improvement in detecting and staging bladder tumors.

Objective To evaluate the significance of color Doppler ultrasound examination of renal blood flow combined with the detection of bone morphogenetic protein-7(BMP-7)in early diagnosis of type 2 diabetic nephropathy.Methods Blood BMP-7 level was tested in 90 patients with type 2 diabetic nephropathy and 30 controls,and parameters of renal blood flow were measured by color Doppler ultrasound examination.Blood BMP-7 level as well as resistant index(RI)of segmental renal artery(SRA)and interlobar renal artery(IRA),were compared between these two groups.Results Compared with controls,blood BMP-7 level gradually decreased with the aggravation of diabetic kidney damage(P＜0.01).The peak systolic velocity(Vmax)and the end diastolic velocity(Vmin)of SRA and TRA were slowed gradually,while RI increased(P＜0.01).Blood BMP-7 level was negatively correlated with IRA's and SRA's RI of IRA and SRA(r =-0.603,P＜0.01;r =-0.652,P＜0.01).Conclusions Color Doppler ultrasound examination of renal blood flow combined with detection of BMP-7 might play an important role in early diagnosis of type 2 diabetic nephropathy.

Objective To investigate the influence of diabetes mellitus (DM) on left ventricular(LV) remodeling in patients with acute ST-segment elevation myocardial infarction (STEMI) treated by primary percutaneous coronary intervention (PCI) within 12 hours of symptom onset. Methods Four hundred and fifty-one consecutive patients with acute STEMI treated by primary PCI were prospectively enrolled in the current study. Baseline, angiographic and PCI features and prevalence of LV remodeling at one-week during hospitalization and 6-month clinical follow-up by two-dimensional echocardiography were compared between 93 diabetic and 358 non-diabetic patients. Results Despite similar baseline clinical and angiographic characteristics, symptom-to-door time was longer (399±106 min vs. 321±116 min, P=0.006) and prevalence of multivessel disease was higher (65.6%vs. 51.7%, P=0.02) in diabetic patients. More patients in diabetic group had LV remodeling at 6-month clinical follow-up (29.0%vs. 17.3%, P=0.01), and DM was an independent predictor of LV remodeling (RR 2.1, 95%CI 1.31-4.79, P=0.02). The rate of rehospitalization due to heart failure did not differ between diabetic and non-diabetic patients (12.9%vs. 8.1%, P=0.15), however, more adverse events occurred in patients with LV remodeling comparing to those without LV remodeling (25.8% vs. 6.6%, P < 0.001). Conclusions Diabetic patients with STEMI often have an increased risk of LV remodeling after treated by primary PCI. Thus, comprehensive therapeutic strategy for diabetic patients presented with STEMI is required considering the poor prognosis of these patients with LV remodeling.

Objective To explore the value of virtual touch tissue quantification (VTQ ) in the diagnosis of pancreas early damage of patients with hyperuricemia(HUA) .Methods Sixty‐five cases of patients with normal glucose tolerance and HUA (HUA group) and 42 cases of patients with HUA and impaired glucose tolerance (IGT group) were included in the study ,and other 150 health subjects were taken as control group .After routine ultrasound examination ,the pancreas shear wave velocity values (Vs) of different groups were measured by VTQ technology ,and the results were analyzed .Results Compared with the control group ,the rate of the abnormai ultrasonogram of pancreas in IGT group showed obvious increasing trend but there was no significantly difference between the other groups(both P >0 0.5) .The Vs of the normal control group ,HUA group ,and IGT group were (1 2.1 ± 0 1.5)m/s ,(1 4.1 ± 0 1.3)m/s and (1 5.9 ± 0 1.5)m/s ,respectively .The Vs of HUA group and IGT group were higher than that of the control group (both P <0 0.5) ,and the Vs of IGT group was significantly higher than that of HUA group ( P <0 0.5) .Conclusions Hyperuricemia may cause pancreas damage ,and with the disease progress ,the pancreas damage became more serious ,and VTQ technology may play an important role on the diagnosis of pancreas early damage in HUA patients .

OBJECTIVETo investigate miR-20a expression in human glioma and normal brain tissues and its effect on the proliferation of glioma cells in vitro.

METHODSThe expression of miR-20a was detected in human normal brain tissues and glioma tissues by real-time RT-PCR. miR-20a mimics were synthesized and transfected into U251 cells via liposome, and the cell proliferation were detected using MTT assay and flow cytometry.

RESULTSThe glioma tissues showed significantly up-regulated expression of miR-20a compared with normal brain tissues (P=0.035). The expression level of miR-20a was higher in high-grade than in low-grade gliomas. miR-20a mimics significantly enhanced the proliferation of U251 cells and the percentage of S-phase cells.

CONCLUSIONmiR-20a shows potent effect in promoting the growth of glioma cells, suggesting its important role in the pathogenesis of human glioma.

Objective To assess the efficacy, safety and surgical strategies of clipping without coil removal in recurrent aneurysms after previous coil embolization. Methods Five patients with recurrent embolized aneurysms underwent microsurgical treatment in our hospital from May 2012 to July 2014 were chosen. Posterior communicating aneurysms were noted in two patients and anterior communicating ones in three patients. The initial sizes ranged from 3-10 mm in diameter; in these aneurysms, the initial coiling results indicated complete occlusion in 5 patients. The mean recurrence latency was 14 months (ranged from 0.7-30 months). Surgical treatment without coil removal in recurrent aneurysms was performed and their clinical data and treatment efficacy were retrospectively analyzed. Results Microsurgical clippings without coil removal were used in all 5 patients. No postoperative morbidity was observed (one had left arm monoparesis, one had psychiatric symptoms, and one had blepharoptosis and recovered soon); postoperative imaging studies revealed complete occlusion of the aneurysms. There were no recurrent aneurysms during the follow-up period (6 and 12 months after surgery) by CT scan. Conclusion The microsurgical clipping without coil removal for recurrent lesions of embolized aneurysms is effective and safe when it is technically feasible.

Objective To explore the efficacy and safety of Kegel exercise combined with biofeedback electrical stimulation in the treatment of postpartum pelvic floor dysfunction(PFD).Methods A total of 100 postpartum PFD patients diagnosed and treated in Shaoxing Maternal and Child Health Care Hospital from January 2022 to May 2023 were selected and divided into KEG group and combination group according to random number table method,with 50 cases in each group.Patients in KEG group were given Kegel exercise,and patients in combination group were treated with Kegel exercise combined with biofeedback electrical stimulation.The clinical efficacy,pelvic floor electrophysiological indexes,bladder neck mobility,urethral rotation angle and sexual function were compared between two groups.Results The total effective rate of combination group was significantly higher than that of KEG group(x2=4.891,P=0.026).After treatment,the anterior resting average electromyogram value(aEMG),posterior resting aEMG,slow muscle aEMG and fast muscle maximum electromyogram value(mEMG)of pelvic floor muscles and sexual satisfaction scores in two groups were significantly higher than before treatment,bladder neck mobility and urethral rotation angle in combination group were significantly lower than before treatment,the duration of vaginal contraction in combination group was significantly longer than before treatment,and the pain score of coitus in combination group was significantly lower than before treatment(P＜0.05).The anterior resting aEMG,posterior resting aEMG,slow muscle aEMG and fast muscle mEMG of pelvic floor muscles and sexual satisfaction scores in combination group were significantly higher than those in KEG group,bladder neck mobility and urethral rotation angle were significantly lower than those in KEG group,the duration of vaginal contraction was significantly longer than that in KEG group,and the pain score of coitus was significantly lower than that in KEG group(P＜0.05).No complications occurred in both groups after treatment.Conclusion Kegel exercise combined with biofeedback electrical stimulation can significantly improve pelvic floor muscle function,sexual function and urinary function in patients with postpartum PFD with good safety,and its efficacy is better than Kegel exercise.
