Objective:To explore the clinical effect ofpaishitang combined with tamsulosin hydrochloride on the patient with up per urinary calculi after extracorporeal shock wave lithotripsy (ESWL).Methods:120 cases with upper urinary calculi in our hospital from January 2015 to September 2016 were selected and divided into two groups according to the random number table,60 cases in each group.ESWL was given to both groups of patients and provided with tamsulosin hydrochloride postoperation,then paishitang were additionally given to the patients in the observation group.The clinical effect and changes of serum creatinine (Scr),neutrophil gelatinase as sociated lipocalin (NGAL),cystatin C (Cys-C) and glomerular filtration rate (GFR) levels before and after treatment were compared between two groups.Results:The total effective rate of observation group was 96.67％,which was 86.67％ in the control group,no signifi cant difference was found in the total effective rate between the two groups(P＜0.05).The stone discharge rate was 95.00％ in the observation group,which was significantly higher than that of the control group (P＜0.05);the incidence rate of renal colic was 6.67％,which was significantly lower than that of the control group(P＜0.05),the stone discharge time and the duration of hematuria were significantly shorter than those in the control group (P＜0.01).There was no significant difference in the recurrence rate between the two groups within one year (P＞0.05).The serum NGAL and Cys-C levels of both groups were gradually increased while the GFR levels were gradually decreased on the 1st,2nd day postoperation,but all the index mentioned above gradually recovered on the 3rd day postoperation.The levels of NGAL and Cys-C in the observation group were significantly lower than those in the control group on the 1st,3rd day postoperation while the GFR was significantly higher in the observation group than those of control group on the 1st,3rd day postoperation(P＜0.01).No significant difference was found in the Scr at different time points postoperation between two groups(P＞0.05).Conclusion:Paishitang combined with tamsulosin hydrochloride had significant clinical effect on thpatient with upper urinary calculus after ESWL and could effectively improve the renal injury induced by ESWL.

Recombinant human BMP-2 was compounded with chitosan/gelatin/hydroxyapatite(HCG) scaffold and the complex was sterilized by 60Co radiating. Osteoblast isolated from cranial bones of newborn rat was primary cultured and seeded onto the complexes. 3 days after culturing, scanning electron microscope(SEM) was applied to detect the compatibility of the cell with the complex. SEM showed osteoblast attached closely with the complex and grew well in its pores. Then the complexes with osteoblast modification were implanted into athymic nude mice subcutaneously. 8 weeks after implantation, X-ray photograph and histological observation were applied to detect the bone formation of the complexes. Under X-ray a high-density areas consistent with the shape of the implanted complex could be seen. Histological observation also proved there was bone formation in the interspace of the complex. A conclusion was drawn that rhBMP-2 compounded HCG scaffold had good osteogenesis ability in vivo.

Objective To investigate the effect of selenium on proliferation and apoptosis of chondrocytes of articular cartilage cultured in vitro in Kaschin-Beck disease(KBD) patients and normal person, to explore the role of selenium in control of KBD, and to provide evidence for selenium's effect on the growth of normal cartilage cells. Methods The articular cartilage samples of grade Ⅱ and Ⅲ KBD patients were selected according to the national "Clinical Diagnosis of KBD" (GB 16003-1995). Chondrocytes of 5 KBD and 5 non-endemic normal accidentswere separated and cultured in vitro. KBD group and control group were given different doses of selenium (0,0.0125,0.0250,0.0500,0.1000,0.2500,0.5000,1.0000 mg/L, respectively). Methyl thiazolyl tetrazolium (MTT),flow cytometric analysis, and immunocytochemical staining were used to observe the effect of selenium on cell growth and apoptosis in KBD and normal persons. Results MTT results showed that the cell proliferation rate in each dosage group of the control group at the 6th day(0.086 ± 0.025,0.077 ± 0.012,0.073 ± 0.027,0.071 ± 0.017,0.058 ± 0.028,0.052 ± 0.028 and 0.046 ± 0.037) was significantly lower than that of 0 mg/L group(0.138 ± 0.026,all P ＜ 0.05);the average cell proliferation rate was negative( - 0.001 ± 0.001, - 0.003 ± 0.000, - 0.003 ± 0.001and - 0.004 ± 0.001 ) in 0.1000 - 1.0000 mg/L dose group, which was significantly lower than that of the 0 mg/L group(0.025 ± 0.003, all P ＜ 0.05);compared with 0 mg/L group(0. 115 ± 0.011), the KBD 0.2500 mg/L dose group promoted cell proliferation(0.128 ± 0.037, P ＜ 0.05), the KBD 1.0000 mg/L dose group inhibited cell growth (0.071 ± 0.019, P ＜ 0.05). The apoptotic rate of 0.0500 - 1.0000 mg/L dose control group [ (18.88 ± 0.02)%,(17.58 ± 0.01)%, (17.09 ± 0.04)%, (56.00 ± 0.02)%, (57.85 ± 0.03)% ] were higher than that of the 0 mg/L group[(13.51 ± 0.01)%, all P ＜ 0.05];compared with 0 mg/L group[(25.84 ± 0.02)%], the apoptotic rate in KBD 0.0250 - 0.2500 mg/L dose group [ ( 13.69 ± 0.02) %, ( 15.96 ± 0.03 ) %, ( 16.68 ± 0.03 ) %, ( 16.67 ± 0.02) % ]were lower, and the apoptotic rate in 0.5000, 1.0000 mg/L dose group [ (59.58 ± 0.03)%, (73.48 ± 0.04)% ] were significantly higher(all P ＜ 0.05). The Fas expression in KBD 0.0500 - 0.2500 mg/L dose groups[ (41.2 ± 1.5)%,(40.3 ± 2.0)%, (50.2 ± 2.5)%] were lower than those of the same dose control group with selenium intervention [(52.4 ± 1.0)%, (67.2 ± 4.0)%, (75.1 ± 5.0)%, all P ＜ 0.05], the caspase-3 expression in KBD 0.0500,0.1000 mg/L dose groups[ (40.8 ± 1.1 )%, (45.1 ± 2.1 )%] were lower than those of the same dose control group with selenium intervention[ (68.0 ± 3.0)%, (70.6 ± 3.5)%, all P ＜ 0.05 ]. Conclusions Appropriate dose of selenium supplementation (0.1000 - 0.2500 mg/L) could promote the growth of KBD chondrocyte, decrease cell apoptosis,but have a damage when the dose of selenium ＞ 0.5000 mg/L;doses of selenium that could promote the growth of KBD chondrocyte does not mean to promote the growth of normal cartilage cells in vivo.

Objective To investigate the efficiency of radiofrequency ablation (RFA) and microwave ablation (MWA) in treating uterine leiomyoma.Methods The clinical data of thermal ablation with RFA and MWA were retrospectively analyzed in 42 patients.All patients were followed up at least 12 months to observe the therapeutic effects after the treatment.The changes of vital signs and the size of uterine leiomyoma,the score of uterine leiomyoma symptom and quality of Iife(UFS-QOL) were compared after RFA or MWA,the two thermal ablations techniques of clinic efficiency and influence on complications were analyzed.Results 23 patients received treatment of RFA and 19 patients received MWA,the visual analogue scale(VAS)during operation and postoperation were statistically significant differences between the two groups(P ＜0.05).The sizes of uterine leiomyoma were significantly reduced after the thermal ablation,the differences of volume within two groups in different time were statistics significance(P ＜0.05),but there were no statistics significance differences between two groups (P ＞0.05).The symptoms in two groups were improved significantly after treatment and the scores of UFS-QOL were no statistics significance differences between two groups (P ＞0.05).Conclusions Both of RFA and MWA have significant clinic efficiency in treating uterine leiomyoma.Compared with MWA,RFA with lower adverse reactions during operation and postoperation.

Objective To study the influence factors of real-time shear wave elastography(SWE) on the elasticity of focal liver lesions (FLLs) measurement.Methods The mean Young's modulus of 160 FLLs were measured by SWE.The relation between elasticity with different aspects of FLLs were analyzed including postures (supine and left lateral position),respiratory phases (end of inspiratory and expiratory),the probe position (rib and intercostal space) and different operators.Results There were significant differences between different postures and respiratory phases in the elasticity measurement of FLLs by SWE (P ＜0.05).There was no significant difference between robe position and different operators in the elasticity measurement of FLLs by SWE(P ＞0.05).Conclusions The postures and respiratory phases can impact the elasticity measurement of FLLs by SWE.
