Objective To study the influence of Compound Salvia injection combined with cefoperazone sulbactam sodium on renal function and renal interstitial fibrosis in elderly patients with chronic pyelonephritis (CPN).Methods From April 2013 to July 2014, 126 cases of CPN were divided into observation group ( n =63 ) and control group ( n =63 ) according to the order of admission to hospital.All patients were given cefoperazone sulbactam sodium, and patients in observation group were added Compound Salvia injection.The clinical efficacy of treatment were evaluated between two groups, renal function and TGF-β1 were observed and compared before and after treatment in two groups.Results After treatment, HE staining of nephridial tissue showed renal interstitial fibrosis in observation group obvious improved more.The overall response rate of observation patients (90.48%) was significantly higher (74.60%) than control group, and the relapse rate of observation group (1.59%) was significantly lower than control group (14.29%), and there were statistically significant differences (P<0.05).After treatment, urinary albumin (11.4 ±3.1) mg/L, BUN (5.7 ±0.5) mmol/L, and Scr (103.2 ±10.4)μmol/L of observation group were significantly lower than control group, respectively (P<0.05).After treatment, TGF-β1 level (103.4 ±32.5) ng/L of observation group was significantly lower than control group (202.4 ±35.2) ng/L(P<0.05).There was no significant difference in adverse reactions between two groups.Conclusions Compound Salvia injection combined with cefoperazone sulbactam sodium has good efficacy.can significantly improve renal function, delay renal interstitial fibrosis in treatment of elderly patients with chronic pyelonephritis.

Objective To evaluate the effect of Ganoderma lucidum on drug resistance of the cisplantin-resistant ovarian cancer cell line(A2780CP).Methods The A2780CP cells were randomly divided into control group and test group.The cells in control group and test group were incubated in culture media alone and in culture media containing Ganoderma lucidum 0.5 mg/ml for 48 h respectively.The resistance index(RI) of A2780CP was determined by WST-1 assay.The expression of Akt,Bcl-2 and p53 protein was measured by Western blot.Results The RI was significantly deeressed,the expression of Akt and Bcl-2 protein was down-regulated,while p53 protein expression was up-regulated in test group as compared with control group(P<0.05).Conclusion Ganoderma lueidum can reduce the resistance of A2780 CP cells to cisplantin by down-regulating the expression of Akt and Bcl-2 and up-regulating p53 expression in A2780CP cells.

Disasters are traumatic events that are always incongruent with our existing cognitive structures. Immediate negative psychological impact and traumatic related psychiatric disorders are popular among survivals involving the disasters. Super-half of survivals involving the "5" 12" Wenchuan earthquake experienced the symptoms of anxiety or increased arousal. 12.59% of survivals were met with the ASD diagnosis. 21.29% of adults and 10.21% of adolescents were met with the PTSD diagnosis 5 months after the major earthquake. Immediately negative psychological impact and high prevalence of traumatic related psychiatric disorders among survivals were confirmed.More effort should be paid on the disaster related patients in emergency department with psychiatric issues. Also, the long-term psychological service is necessary for Sichuan Pest-Disaster Reconstruction Projects.

Objective To investigate effect of trepibutone tablet combined with ursodeoxycholic acid in treatment of patients with gallstone. Methods 200 cases with gallstone were diagnosed and randomly divided into observation group and control group from February 2013 to February 2014.100 cases in control group were given ursodeoxycholic acid treatment 50 mg/(kg? d),two times per day for six month.On the basis of control group observation group were treated with trepibutone one tablet per day,three times per day,4 weeks for 1 course, 2 weeks of treatment interval between 4 courses, totally for four courses.After treatment, patients were followed up and recorded gallbladder wall thickness, gallbladder functional status. Results After 6 months of treatment in patients with gallbladder wall thickness of observation group ( 2.77 ±0.38 ) mm was superior to control group (3.24 ±0.36)mm(P<0.05).After 6 months of treatment in patients with gallbladder function score of observation group (58.75 ±4.79) was better than control group (53.11 ±5.02) ( P<0.05).Recurrence rate of observation group was 9% better than that of control group 18%(χ2 =3.468,P<0.05)after treatment for 6 months.Conclusion Effect of trepibutone tablet combined with ursodeoxycholic acid in treatment of patients with gallstone is well.There is no obvious side effects during the treatment.

Objective: To investigate the diagnostic value of non-specific diagnostic indicators for bacterial neonatal late-onset sepsis. Methods: A total of 55 children with bacterial neonatal late-onset sepsis in Langfang People's Hospital were selected as sepsis group.Another 67 cases of non-infected newborns were selected as control group.White blood cell, platelet and C-reactive protein were retrospectively analyzed for diagnostic value.Meanwhile, percentage of neutrophils and mean platelet volume were analyzed for diagnostic value. Results: When the bacterial neonatal late-onset sepsis occurred, the sensitivity(41.8%), specificity(95.6%) and positive predictive value(92.0%) of C-reactive protein were high.The sensitivity(18.2%, 10.9%), positive predictive value(71.4%, 85.7%) of white blood cell and platelet were low, but specificity(94%, 98.5%) was high.The percentage of neutrophils [(62.01±22.16)] and mean platelet volume[(11.60±0.98)] were higher than those of the control group [(36.58±11.06), (10.88±0.95)], and the differences were statistically significant(all P<0.05). Conclusion C-reactive protein has greater diagnostic value for bacterial neonatal late-onset sepsis.The percentage of neutrophils and mean platelet volume have some diagnostic value.

Objective:To study the safety of different peripherally inserted central catheter (PICC) dressing replacement frequencies in preterm infants.Method:From June 2017 to February 2020, preterm infants were enrolled in this prospective randomized controlled study. Preterm infants with PICC were randomly assigned into 7 d, 11 d and 14 d dressing replacement groups using online randomization software. Polyurethane transparent dressing and the same dressing replacement method were used in all three groups. The incidences of catheter-related bloodstream infection (CRBSI) and positive skin bacterial culture at dressing site were compared among the three groups.Result:A total of 296 cases were enrolled, including 96 cases in the 7 d group, 108 cases in the 11 d group and 92 cases in the 14 d group. The incidences of CRBSI in three groups were 2.5/1 000 catheter day in 7 d group, 1.1/1 000 catheter day in 11 d group and 0.8/1 000 catheter day in 14 d group. The incidences of catheter pathogen colonization were 1.0% in 7 d group, 0.9% in 11 d group and 0% in 14 d group. The positive rates of skin bacterial culture at dressing site were 1.0% in 7 d group, 2.8% in 11d group and 2.2% in 14 d group. The incidences of PICC exit site infection in three groups were 1.0% in 7 d group, 0.9% in 11d group and 1.1% in 14 d group and no significant differences existed among the groups ( P>0.05). Gram-positive cocci were the main bacteria [91.7% (11/12)] of CRBSI and skin bacterial culture at dressing site and gram negative bacilli accounted for 8.3% (1/12). No fungal infection were found. Conclusion:It is safe to replace the PICC dressing in premature infants as needed within 14 days if the dressing is intact without curling, bleeding and exudation.

OBJECTIVE: To explore the effect of long-term low-dose ionizing radiation exposure on arterial vascular elasticity in female residents. METHODS: A cluster random sampling method was used,95 female residents in 2 regions with high external γ radiation dose rate in the high radiation background area( HBRA) in Yangjiang City were selected as the HBRA group,and 96 female residents from the control area( CA) in Enping City were chosen as the CA group. The height,body mass,waist circumference,hip circumference and blood pressure were measured in individuals of these two groups. The fasting blood samples of elbow vein were collected to measure high-density lipoprotein cholesterol( HDL-C),low-density lipoprotein cholesterol( LDL-C),triglycerides( TG) and blood glucose. The cardio-ankle vascular index( CAVI) was measured using the blood pressure and pulse check device. RESULTS: The CAVI of the CA and HBRA groups were( 8. 09 ±1. 03) and( 8. 35 ± 1. 60) m/s,respectively. The abnormal rates of CAVI were 25. 00% and 29. 47%,respectively. The results of multiple linear regression analysis showed that after adjustment for age,HDL-C,LDL-C,TG,hypertension,abnormal glucose metabolism and abdominal obesity,the CAVI adjustment mean values of the CA and HBRA groups were8. 19 and 8. 25 m/s,respectively. The HBRA group was about 0. 73% higher than the CA group,but the difference was not statistically significant( standardized partial regression coefficient = 0. 021,P > 0. 05). After matching age of both groups,the difference of the adjusted mean of CAVI between the two groups was not statistically significant( P > 0. 05).CONCLUSION: Long-term low-dose radiation exposure is not associated with atherosclerosis in female population.
