Objective To discuss the mechanism of Liuwei Dihuang Decoction against renal interstitial fibrosis. Methods The rat models of renal interstitial fibrosis were induced by 5/6 nephrectomy, and were randomly divided into sham-operation group, model group, Liuwei Dihuang Decoction group and enalapril group. Liuwei Dihuang Decoction group was given 6.25 g/(kg?d) of Liuwei Dihuang Decoction for gavage, enalapril group was given 10 mg/(kg?d) enalapril for gavage, sham-operation group and model group were given 10 mL/(kg?d) of distilled water for gavage, 1 time per day for 12 weeks. Expressions of HIF-1α, CollI, and CollIII in kidney tissue were detected by immunohistochemistry. Results Compared with the sham-operation group, the expressions of HIF-1α, CollI, and CollIII of renal tissue in the model group significantly increased (P<0.05). Compared with the model group, Liuwei Dihuang Decoction group and enalapril group can inhibit the expressions of HIF-1α, CollI, and CollIII (P<0.05), and Liuwei Dihuang Decoction group was better than enalapril group (P<0.05). Conclusion The mechanism of Liuwei Dihuang Decoction against renal interstitial fibrosis may improve the renal tissue of chronic hypoxia to play the role of preventing renal interstitial fibrosis by decreasing the expressions of HIF-1α, CollI, and CollIII.

Objective To observe the effect of Chinese yam polysaccharide on the expression of hypoxia inducible factor-1α (HIF-1α) and vascular endothelial growth factor (VEGF) in rats with renal ischemia reperfusion injury. Methods SD rats were randomly divided into sham operation group, model group and Chinese yam polysaccharide group. Renal ischemia reperfusion injury model in rats was prepared. Seven days before operation, Chinese yam polysaccharide group was gastrically administrated with yam polysaccharide (200 mg/kg) daily, sham operation group and model group with same volume of saline respectively. BUN and SCr were detected postoperative 6 h, the protein expression of HIF-1αin renal tissue was detected by Western Blot, and HIF-1αand VEGF mRNA expression in renal tissue were detected by RT-PCR. Results Compared with sham operation group, serum levels of BUN and SCr of model group and Chinese yam polysaccharides group increased (P<0.01), and the mRNA and protein expression of HIF-1α, mRNA expression of VEGF in renal tissue increased (P<0.01). Compared with model group, serum levels of BUN and SCr of Chinese yam polysaccharide group decreased (P<0.01), and HIF-1α mRNA and protein expression, VEGF mRNA expression in renal tissue increased (P<0.01). Conclusion Chinese yam polysaccharide has obvious protective effect on renal ischemia reperfusion injury, which may be related with up-regulation of HIF-1αexpression and induction of VEGF expression.

Objective: To analyze the influencing factors for hospitalization costs among stroke patients with different subtypes, so as to provide the reference for reducing the economic burden of patients. Methods: Data of patients with hemorrhagic or ischemic stroke who were discharged from hospitals in Nanshan District, Shenzhen City from January 1, 2016 to December 31, 2021 were collected through Hospital Information System. Hospitalization costs were analyzed between hemorrhagic and ischemic stroke patients, and factors affecting hospitalization costs among stroke patients with different subtypes were identified using a structural equation model. Results: A total of 10 298 patients with stroke were recruited, including 2 820 patients with hemorrhagic stroke (27.38%) and 7 478 patients with ischemic stroke (72.62%). The patients with hemorrhagic stroke had a median duration of hospital stay of 19.00 (interquartile range, 18.00) d, and a median hospitalization cost of 26 759.48 (interquartile range, 51 000.87) Yuan. The patients with ischemic stroke had a median duration of hospital stay of 12.00 (interquartile range, 10.00) d, and a median hospitalization cost of 12 199.87 (interquartile range, 13 290.20) Yuan. Structural equation model analysis showed that department of hospitalization, discharge status, ways of leaving hospital, surgery and hypertension had direct effects on hospitalization costs and indirect effects on hospitalization costs through duration of hospital stay among hemorrhagic stroke patients, and duration of hospital stay had the highest total effect (0.684), followed by surgery (0.632). Employment status, admission route, department of hospitalization, ways of leaving hospital, payment mode, surgery and dyslipidemia had direct effects on hospitalization costs and indirect effects on hospitalization costs through duration of hospital stay among ischemic stroke patients, and duration of hospital stay (0.746), surgery (0.424) and department of hospitalization (0.151) ranked the top three in total effects. Conclusion The hospitalization cost is relatively high among stroke patients in Nanshan District, and duration of hospital stay and surgery have great influence on hospitalization costs among stroke patients with different subtypes.
