The prevalence of renal involvement in primary Sjogren′s syndrome: a meta-analysis / 中国医师杂志

Objective:Renal involvement in primary Sjogren′s syndrome (pSS) has been considered rare, and recent studies have shown that there was a large difference in the prevalence of the disease, which has been reported to range from 0.03% to 67%. The meta-analysis was to determine the prevalence of renal involvement in pSS patients.Methods:The study on pSS renal involvement was conducted in Pubmed, Embase and Cochrane Library from January 2002 to May 2019. After logarithmic conversion of the prevalence rate, meta-analysis of random effect model was carried out to explore the prevalence of pSS renal involvement. Subgroup analysis and meta regression analysis were used to explore the source of heterogeneity. We also performed sensitivity analysis and assessments of publication bias by Begger′s test.Results:The meta-analysis included eighteen observational studies of 8 888 participants. The result in random effects model showed that the combined prevalence was 9.0% (95% CI: 6.0%-12.0%), with significant heterogeneity between these studies ( I2=97%, P<0.01). The source of heterogeneity was explained by a stratified analysis of region, type of study, and the diagnostic criteria for renal involvement. Sensitivity analysis showed that the result was robust and Begger′s test did not detect the presence of publication bias. Conclusions:The prevalence of renal involvement in pSS is 9.0%. Due to huge heterogeneity, large multicenter prospective studies will be needed to determine its prevalence and the relationship between pSS and kidney.

Objective To study the influence of intravenous injection of dezocine and fentanyl under general anesthesia on analepsia and analgesia after children appendectomy.Methods 86 children needed peritoneoscope appendectomy were enrolled in the study.All patients were randomized into two groups.The patients in group A were given intravenous injection of dezocine at half an hour before the end of the operation.The patients in group B were given intravenous injection of fentanyl before the end of the operation.The operation length,the postoperative catheter removal time and the heart rate,respiratory rate,mean arterial pressure,blood pressure saturability at the time of stopping using narcotic (T1),the time of catheter removal (T2),10min after catheter removal (T3) of the two groups were observed and recorded.At half an hour after catheter removal,Riker sedation-agitation scale and FLACC of two groups were estimated.Results The heart rate[(112.47±8.06)beats/min,(111.29±9.03)beats/min] and mean arterial pressure[(69.49±7.33)mmHg,(68.72±6.93)mmHg] of group A at T2,T3 were significantly lower than those of group B[heart rate: (126.98±7.24)beats/min,(131.54±8.62)beats/min and mean arterial pressure: (76.81±5.18)mmHg,(72.05±3.76)mmHg, heart rate tT2=3.294,tT3=5.018;mean arterial pressure tT2=4.029,tT3=2.287,all P<0.05].Besides,the FLACC score[(3.62±0.73)points] and Riker score[(2.93±0.75)points] of group A at half an hour after catheter removal were significantly lower than those of group B[(5.06±0.92)points,(3.96±1.17)points,tFLACC=6.390,tRiker=2.119,all P<0.05].Conclusion Intravenous injection of properdezocine at half an hour before the end of the operation has good postoperative analgesia effect for children appendectomy and children wake up in a more stable state,and the occurrence rate of postoperative analgesia and adverse reaction is low, so it has less influence on cardiovascular reaction and is applicable for clinical application.

Study on the Mechanism of Butylphthalide Delaying Renal Fibrosis of Mice Model with Unilateral Ureteral Obstruction / 实用医学杂志

Objective To study on the possible mechanism of butylphthalide delaying renal fibrosis of mice with obstructive nephropathy. Methods Totally 72 male CD-1 mice of clean grade were selected and randomly assigned into 4 groups: sham operation group (Sham), model group (UUO), control group (ACEI) and treatment group (NBP). The mice in the control group (ACEI) and the treatment group (NBP) were given benazepril and butylphthalide by gavage, and the mice in sham operation group (Sham) and model group (UUO) were given normal saline by gavage. Six mice were sacrificed at the third, 7th, 14th day, respectively. The obstructive renal tissue was selected for immunohistochemical staining and western blot. Results (1)With the longer time of ureteral obstruction, the expression of Nrf-2 was gradually strengthened in time-dependent manner;(2)Compared with the model group, the levels of Nrf-2 and γ-GCS in butylphthalide group were significantly increased, and the expression of type Ⅰ collagen was decreased significantly (P < 0.05). The expression of Nrf-2 and γ-GCS in each time points was stronger than that in the benazepril group (P < 0.05). Correlation analysis showed that: there was a positive correlation between Nrf-2 and γ-GCS (r = 0.930) and a negative correlation between Nrf-2 and the expression level of type Ⅰ collagen(r = -0.859). Conclusion Butylphthalide can relieve renal interstitial injury caused by oxidative stress and delay the progress of renal interstitial fibrosis by activation of Nrf-2 pathway and up-regulated expression ofγ-GCS.

Objective To explore the impact of different doses of butylphthalide on renal interstitial fibrosis in mice with obstructive nephropathy, and to discuss the correlation between Nrf-2 expression level and renal interstitial fibrosis. Methods Totally 72 male CD-1 mice of clean grade were selected and randomly assigned into 4 groups:sham operation group (Sham), model group (UUO), low dose of butylphthalide group (NBPL) and high dose of butylphthalide group (NBPH). In addition to the control group, UUO model was established in other three groups. NBPL group was given NBP 150 mg/(kg· d) by gavage since postoperative day 1,NBPH group was given NBP 220 mg/(kg·d) by gavage. Sham group and UUO group were given equal volume of saline by gavage. Six mice were sacrificed at the third, 7th, 14th day, respectively. The obstructive renal tissue was selected for immunohistochemical staining and Western blot assay. The expression levels of Nrf- 2 and type Ⅰ collagen were detected by Western blot assay. Results The IOD value of type Ⅰ collagen was increased with time in UUO group, and which showed a gradual decreasing trend in Sham group, NBPL group and NBPH group (P<0.05). The IOD values at different time points were significantly higher in UUO group, NBPL group and NBPH group compared to those of Sham group. The IOD values were significantly decreased in NBPL and NBPH groups than that of UUO group, and IOD value was lower in NBPH group than that of NBPL group (P<0.05). Western blot assay showed that IOD values of Nrf-2 and type Ⅰ collagen at 7 d and 14 d were increased in UUO group, NBPL group and NBPH group compared with those of Sham group. The IOD values of Nrf-2 protein were increased, and IOD values of type Ⅰcollagen were decreased, in NBPL group and NBPH group than those of UUO group. The IOD value of Nrf-2 protein was decreased in NBPL group than that of NBPH group, but the IOD value of type Ⅰcollagen was increased in NBPL group than that of NBPH group (P<0.05). Conclusion NBP can improve renal interstitial fibrosis in UUO mice, which may be related with the increased expression of Nrf-2 and the down-regulated expression of type I collagen.
