(5.89 ± 2.24) mg/L] in amlodipine group , P<0.01 all .Conclusion:Amlodipine can more significantly reduce levels of TNF‐α,IL‐6 and hsCRP ,inhibit inflammatory reaction than those of nifedipine and contribute to blood pressure control in patients with essential hypertension .

Aim To investigate the effects of breviscapine(Bre)on Na+,K+-ATPase activity of proximal tubule(PT) and its renal protection in early diabetic rats. Methods The rats were divided into three groups: diabetic model (DM group), Bre treatment (Bre group) and normal control (NC group). Rats were administrated with Bre(20 mg?kg-1?d-1, ip) in Bre group, with normal saline(ip) in DM and NC groups for four weeks after diabetes induction with streptozotocin (STZ 65 mg?kg-1, ip) in Bre and DM groups. The urine and blood samples were collected from two intra-ureteral cannulas and the heart, respectively, under anesthesia four weeks after diabetes induction. After one of the renal arteries being perfused, the renal cortex was incubated and PT segments were microdissected freehand under microscope before the Na+,K+-ATPase activity in the segments were assessed by liquid scintillation counter. The blood glucose, levels of creatinine in serum and in urine were assayed. The microalbumin , ?2-microglobulin(?2-MG) of urine and endogenous digitalis-like substance (EDLS) of serum were measured respectively by radioimmunoassay. Results The PT Na+,K+-ATPase activity in NC group was(959.11?117.35) pmolPi?mm-1?h-1, and that in DM group was significant higher for (1893.53?383.90) pmolPi?mm-1?h-1 than it(P

Objective To explore the effect of chronic low lead exposure on molecular pathological mechanisms of learning and memory of rats at the developmental stage Methods The changes of N methyl D aspartate receptor 1 (NMDAR 1) mRNA expression in rat hippocampus were observed by using digoxigenin labled anti sense oligonucleotide probes in situ hybridization technique Results The changes in NMDAR 1 mRNA levels in Pb exposed rat hippocampus were found to be dependent upon the developmental period of exposure and the region of the hippocampus analyzed Hippocampal NMDAR 1 mRNA levels increased significantly in the CA1 (18 75%) and CA3 (13 2%) ( P

Objective To improve the level of diagnosis and treatment of the sharp injury in the back. Methods 47 cases which were treated from Jan 1991 to May 2000 were reviewed. ResultsAmong 37 cases who underwent the exploration, 5 cases died. Among 10 cases who underwent conservative treatment, 2 cases died. ConclusionThe condition of sharp injury in the back is very complicated,it is easy to be misdiagnosed, the mortality is high. Saving should be equalled with the diagnosis and treatment. The application of wound exploration, abdominal puncture, ultrasound examination and X-ray checking is valuable to the diagnosis. The patients with operation indications should be operated at once,while the others should be observed for some time to prevent the delayed clinical manifestation.

Objective To investigate management strategy of minimally invasive surgery for common bile duct stones. Methods Three hundred and four cases of common bile duct stones were divided into 3 groups receiving respectively endoscopic papillary balloon delation plus laparoscopic cholecystectomy ( EPBD group, 35 cases ), endoscopic sphincterotomy plus LC ( EST group, 138 cases), and Laparoscopic common bile duct exploration plus LC (LCBDE group, 131 cases). Results There was no significant difference in treatment success rate, short-term complications and bile duct retained stones among these three group ( x2 = 1. 930, 0. 038, and 0. 427 respectively, P > 0. 05 ). There was significant difference among these three groups in operation time ( F = 17.941, P = 0. 000 ), and the operation time in LCBDE group was shorter than that in other two groups( EPBD-EST: P = 0. 122, EST-LCBDE:P = 0. 000, EPBD-LCBDE:P = 0. 020 ). There was significant difference among these three groups in postoperative hospital stay (F =24. 016,P =0. 000) ,and the postoperative hospital stay in EPBD group was shorter than that in other two groups ( EPBD-EST: P = 0. 000, EST-LCBDE : P = 0. 198, EPBD-LCBDE : P = 0. 000 ). In EPBD group,bile duct recurrent stones was found in 2 cases(6. 7% ) and cholangitis in 1 case(33% ) and no duodenal papilla stenosis was encountered; In LCBDE group, bile duct recurrent stones were found in 7 cases (6. 0% ), cholangitis in 3 cases ( 2. 6% ), and there was no duodenal papilla stenosis; In EST group, bile duct recurrent stones were complicated in 18 cases ( 15.8% ), duodenal papilla stenosis in 9 cases (7.9%), and cholangitis in 14 cases( 12. 3% ). There were significant differences among these three groups for these three complications( x2 = 6. 482, 9. 160, and 12. 020 respectively,P < 0. 05 ), and the rate of complications in EST group was higher than that in other two groups. Conclusion For common bile duct stones, EPBD is the first choice followed by LCBDE while EST is only indicated for very few cases.

Objective To investigate the clinical outcomes derived from Ningmitai combined with tamsulosin to prevent double-J stent syndrome after laser lithotripsy with ureteroscope. Methods 117 patients underwent laser lithotripsy with ureteroscope and then placed a double-J stent for draining were collected from January 2010 to January 2013. Patients with double-J stent placement were divided into four groups determined by dosage regimen. Tamsulosin group (30 cases) was treated with tamsulosin (0.4 mg once daily) lonely, Ningmitai group (29 cases) was treated with Ningmitai (1.52 g, trice time a day) lonely, tamsulosin combined Ningmitai group (30 cases) was treated with tamsulosin and Ningmitai at the same time, operation control group (28 cases) was neither tamsulosin nor Ningmitai. The catheter was removed on the 3rd day post-lithotripsy and then remained double-J stent for 1 month. The scores of urinary tract, pain and the incidence of gross hematuria were assessed. Results The significant differences in the improvement of symptom score (χ2=22.038, P=0.000), pain score (χ2=9.876, P=0.020) and hematuria (χ2=8.000, P=0.046) were found among tamsulosin group, Ningmitai group, and tamsulosin combined Ningmitai group. The number of patients with symptomless, slight symptom in tamsulosin combined Ningmitai group were higher than those of tamsulosin group, Ningmitai group, operation control group (symptomeless:14 vs. 6, 3 and 2 cases;slight symptom:13 vs. 9, 5, 4 cases). The number of patients with>Ⅱpain score (7 vs. 9, 14, 17 cases) and incidence of hematuriag [26.6%(8/30) vs. 56.7%(17/30), 58.6% (17/29), 53.6% (15/28)] were lower in tamsulosin combined Ningmitai group than those of tamsulosin group, Ningmitai group, operation control group. The drug combination of Ningmitai with tamsulosin had the synergism to relived symptom and pain, and showed the more obviousthan lonely use. Conclusion The drug combination of Ningmitai with tamsulosin can be used in clinic for prophylactic purpose to prevent double-J syndrome.

Objective:To explore the correlation of serum albumin level at admission with clinical prognoses in patients with acute traumatic brain injury (TBI).Methods:One hundred and fifty-four patients with acute moderate-extreme severe TBI (Glasgow Coma Scale [GCS] scores of 3-12 at admission) in Department of Neurosurgery, General Hospital of Western Theater Command from January 1, 2019 to December 31, 2020 were chosen. The comprehensive clinical data of these patients were collected, including age, gender, GCS scores, serum albumin level (hypoalbuminemia defined as<35 g/L), hemoglobin level, comorbidities, treatment measures, and prognoses 6 months after discharge (poor prognosis defined as Glasgow outcome Scale [GOS] scores of 1-2, and good prognosis defined as GOS scores of 3-5). Univariate and multivariate Logistic regressions were used to identify the independent factors for clinical prognoses of these patients, and differences in poor prognosis rate, length of ICU stay, and total hospital cost were compared between different groups.Results:Among the 154 patients, 43 had poor prognosis and 111 had good prognosis. Serum albumin level at admission ( OR=0.916, 95% CI: 0.843-0.996, P=0.001) and GCS scores at admission ( OR=0.701, 95% CI: 0.594-0.828, P<0.001) were independent factors for prognosis. Patients with hypoalbuminemia ( n=70) displayed significantly higher poor prognosis rate, longer ICU stays, and increased total hospitalization cost compared with those without hypoalbuminemia ( n=84, P<0.05); specifically, in patients with GCS scores of 9-12 at admission ( n=58), those with hypoalbuminemia ( n=27) exhibited significantly higher poor prognosis rate, longer ICU stays, and higher total hospitalization cost than their non-hypoalbuminemia counterparts ( n=31, P<0.05); similarly, in patients with GCS scores of 3-8 at admission ( n=96), those with hypoalbuminemia ( n=74) had significantly higher poor prognosis rate than their non-hypoalbuminemia counterparts ( n=22, P<0.05). In patients with good prognosis, those with hypoalbuminemia ( n=56) showed significantly longer total hospital stays, prolonged ICU stays, and increased total hospitalization cost compared with those without hypoalbuminemia ( n=55, P<0.05). Conclusion:Low serum albumin level at admission is likely to lead to poor prognosis, prolonged ICU stays and increased total hospitalization cost in patients with acute TBI.
