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.

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 explore the CT findings of mucoepidermoid carcinoma (MEC) of the tracheobronchial tree and improve the diagnostic accuracy. Methods The CT images, histopathological and clinical data in 24 patients with pathologically proved MEC of the tracheobroncbial tree were retrospectively analyzed. Results The clinical symptoms included cough, sputum, fever, wheezing, chest pain and hemoptysis. The patient was proved to be low-grade (n=19) and high-grade (n=5) MEC histopathologically. One lesion was located in trachea, 6 in main bronchus, 12 in lobar bronchus and 5 in segmental, subsegmental and distal bronchus. The tumor presented as no-invasive endotracheobronchial well-defined round-like nodule (n=13, locating in lobar and higher bronchus) and columnar sharp (n=3, locating in main bronchus), or intra-and-extraluminal well-defined round-like nodule or mass (n=6, locating in lobar and lower bronchus) and irregular mass with invasive pattern (n=2, high-grade type). The density of lesion was similar to the muscule and the calcification within lesion was showed in 4 patients on non-enhanced CT. The lesion had marked enhancement in 17 patients on enhanced CT. Obstructive changes were found in 20 patients. Conclusion MEC of the tracheobronchial tree is usually low-grade malignancy and locates in main and lobar bronchus with no-invasive well-defined airway mass, marked enhancement and calcification on CT.

Objective To investigate the angiographic manifestation of the proper esophageal artery (PEA),the hish risk factom for the presence of the anomalous PEA in hemoptysis and to evaluate the safety of transcatheter aaefial embolization(TAE) of the PEA using gelatin sponge(GS).Methods Selective esophageal arteriography WSS performed in forty-three patients with hemoptysis,including 15 cases of pulmonary tuberculosis,18 cases of bmnchiectasis,7 cases of posttuberculous bronchiectasis and three cases of lung cancer. One case experienced failure of bronchial arterial embolization. The angiographic manifestation of the PEAs Was studied.The complications of the procedure and clinical results were observed in the patients who underwent TAE using GS.Results Thirty-nine PEAs were catheterized selectively in 37 patients(86.0%).Eighteen anomalous PEAs(46.2%)were catheterized selectively in 17 patients (45.9%).The anomalous PEAs showed tortuosity,dilatation,hyperplasia,shunting with pulmonary artery and anastomosis with the bronchial artery.All lesions involved basal segment of inferior pulmonary lobar. Bronchiectasis Was the most frequent disease for PEA abnormality. No complications occurred and satisfactory curative effect Was achieved with TAE of the anomalous PEAs.Conclusions It is necessary to perform selective proper esophageal arteriography when the lesion involves basal segment of inferior pulmonary lobar in hemoptysis.Supplemental TAE of the anomalous PEA using GS is safe and valuable in the management of hemoptysis.
