Objective:
To investigate the factors affecting drug-induced liver injury among patients with pulmonary tuberculosis in Ningbo City from 2015 to 2019, so as to provide insights into the prevention of drug-induced liver injury.
Methods:
Demographic features, presence of drug-induced liver injury, and disease history prior to anti-tuberculosis therapy were captured from patients with pulmonary tuberculosis in Ningbo City from 2015 to 2019 through the Tuberculosis Management Information System of the Chinese Disease Control and Prevention Information System and Ningbo Regional Diagnosis and Treatment Information Platform. Factors affecting drug-induced liver injury was identified using the multivariable logistic regression analysis.
Results:
A total of 9 397 patients with pulmonary tuberculosis were enrolled, among whom 66.43% ( 6 242 case ) were male, 65.89% ( 6 192 cases ) were at ages of <60 years, and 92.35% ( 8 678 cases ) were treatment-naïve. There were 1 425 patients with drug-induced liver injury (15.16% incidence), including 729 cases with grade 1 (51.16%), 24 cases with grade 2 (1.68%), 7 cases with grade 3 (0.49%), 7 cases with grade 4 ( 0.49% ), and 658 cases with ungraded drug-induced liver injury ( 46.18% ). The median duration between drug administration and development of drug-induced liver injury was 24 ( interquartile range, 44 ) days. Multivariable logistic regression analysis identified treatment-naïve ( OR=1.464, 95%CI: 1.153-1.859 ) and history of liver disease ( OR=2.001, 95%CI: 1.709-2.342) as risk factors for drug-induced liver injury in patients with pulmonary tuberculosis.
Conclusion
The incidence of drug-induced liver injury was 15.16% among pulmonary tuberculosis patients in Ningbo City from 2015 to 2019. Treatment-naïve and a history of liver disease are associated with drug-induced liver injury among patients with pulmonary tuberculosis.

[ ABSTRACT] AIM:To establish the insulin resistance rat model for evaluating the correlation of omentin-1 level and insulin resistance.METHODS: SPF male Wistar rats ( n =30 ) were randomly divided into normal control group (NC, n=15) and high-fat diet group (HF, n=15).The rats in NC group were fed with basic diet.The insulin resistant model was established by feeding the rats with high-fat diet in HF group.After 10 weeks, 5 rats in each group were as-sessed by the technique of hyperinsulinaemic-euglycaemic clamp.After the insulin resistant model was successfully estab-lished, the body weight and fasting blood glucose were detected.The concentration of fasting serum omentin-1 was analyzed by ELISA.Fasting serum insulin was measured by radioimmunoassay.RESULTS: No difference of fasting blood glucose between the 2 groups was observed.The level of fasting serum insulin in HF group was significantly higher than that in NC group ( P <0.05 ) .The level of serum omentin-1 in HF group were significantly decreased compared with NC group (P<0.01).Pearson’s correlation analysis showed that negative correlations between serum omentin-1 and fasting serum insulin (r=-0.654,P<0.01), serum omentin-1 and free fatty acid (r=-0.446, P<0.05) was found.CONCLU-SION:In rats, serum omentin-1 level began to decrease at insulin resistance stage.As serum omentin-1 level decreased, the basal insulin level increased, indicating that decreased serum omentin-1 level may be an early factor of IR, diabetes and cardiovascular diseases.

Objective To investigate podocyte number, the expression of nephrin and transforming growth factor-β1(TGF-β1) in adriamycin-induced-nephropathy rat model and its significance. Methods The rat adriamycin nephrosis model was constructed to detect blood and urine biochemical indicators and observe the pathological changes of renal tissues by light microscope and electron microscope. The expression levels of nephrin and TGF-β1 as well as the podocyte number were examined at different time points by immunohistochemistry. Results The pathological changes of the renal tissues were obvious. Nephrin presented a weak signal at the end of the first week (P<0.05). TGF-β1 started to increase (P<0.05) while the podocyte number started to decrease at the end of the eighth week (P<0.05). Expression of nephrin was negatively correlated with the P<0.05) and serum creatinine (r=-0.71, P<0.05). Expression of TGF-β1 was blood urea nitrogen (r=0.62, P<0.05) and serum creatinine (r=0.59, urinary protein (r=-0.63, P<0.05), blood urea nitrogen (r=-0.72, P<0.05) and serum creatinine (r=-0.76, P<0.05); it was positively correlated with nephrin (r=0.78, P<0.01) but negatively correlated with TGF-β1 (r=-0.64, P<0.05). Conclusion The acute and chronic adriamycin nephrosis models were twice every two weeks. The genesis and development of proteinuria are closely related to the abnormal expression of nephrin. Focal segmental glomerulosclerosis occurs when the podocyte number decreases and TGF-β1 accelerates it.

Objective To observe the effect of shock lymph drainage on multiple organ injury of rats with traumatic hemorrhagic shock (THS) and discuss the relating mechanism. Methods Male Wistar rats were divided into control group, lymph drainage group and lymph return group. The THS model was established in lymph drainage group and lymph return group, when the shock mesenteric lymph was drained in lymph drainage group. The change of the mean arterial pressure ( MAP), the biochemical indices of liver, kidney, myocardium and acid-base, the morphology, ATP contents and ATPase activities of lung, kidney, liver and myocardium were observed. Results The MAP at multiple time points after 80 minutes of infusion, the ATP contents and ATPase activities of multiple organs in lymph drainage group were higher than those in lymph return group. Multiple biochemical indices in lymph drainage group were superior to those in lymph return group, with statistical difference. The inflammation, congestion, degeneration and necrosis were found in organs of lymph return group, but only mild lesions could be seen in lymph drainage group. Conclusions The shock lymph drainage can alleviate multiple organ injury of THS rats, mechanism of which is correlated with improvement of the energy metabolism and maintenance of MAP and acid-base status.
