Objective:To evaluate the clinical curative effect of Shenqi-Gushen Decoction on patients with chronic renal failure (CRF) of qi-yin deficiency syndrome. Methods:A total of 82 patients with CRF meeting inclusion criteria in the hospital were enrolled between June 2018 and January 2021. According to random number table method, they were divided into control group and observation group, 41 in each group. The control group was treated with routine western medicine, while the observation group was treated with Shenqi-Gushen Decoction on basis of control group. All were treated for 2 months. Before and after treatment, Traditional Chinese Medicine (TCM) symptoms were scored. The serum creatinine (SCr) and blood urea nitrogen (BUN) were detected by full-automatic biochemical analyzer. The levels of IL-6, TNF-α and hypersensitive C-reactive protein (hs-CRP) were detected by ELISA. The levels of hemoglobin (Hb), serum albumin (Alb) and prealbumin (PA) were detected by immune scatter turbidity. And clinical curative effect was evaluated. Results:The total response rate [80.5% (33/41) vs. 46.3% (19/41); χ2=5.861, P=0.015] in the observation group was significantly higher than that of the control group. After treatment, scores of TCM symptoms in observation group was significantly lower than that of the control group ( t=23.468, P<0.01), levels of serum SCr [(421.19 ± 43.82) μmol/L vs. (488.71 ± 48.39) μmol/L, t=6.623] and BUN [(19.54 ± 1.26) mmol/L vs. (24.12 ± 2.42) mmol/L, t=10.749] were significantly lower than those in the control group ( P<0.01), and eGFR [(47.71 ± 4.68) ml/min vs. (42.51 ± 4.55) ml/min, t=5.101] was significantly higher than that of control group ( P<0.01). After treatment, levels of serum IL-6, TNF-α and hs-CRP in observation group were significantly lower than those in the control group ( t=3.412, 3.714, 2.466, P<0.01 or P<0.05), while levels of Hb, Alb and PA were significantly higher than those in the control group ( t=4.462, 5.807, 2.256, P<0.01 or P<0.05). Conclusion:Shenqi-Gushen Decoction combined with routine western medicine can improve clinical syndromes, renal function, micro-inflammation response, nutrition status and curative effect in patients with CRF of qi-yin deficiency syndrome.

Objective: To investigate the stress and stress distribution generated on each component of implant prosthodontic system and surrounding cortical bone when different diameters of screw-access hole (SAH) were prepared on molar crown. Methods: A fimite element(FE) model of partial mandible without first molar was set up, and an Bego implant was insert into it. A total of 5 models of the crown were computer-simulated by varying the diameter (Φ = 0-4 mm) of the SAH. The loading forces were 200 N axially (0°) and 100 N obliquely (45°) respectively on occlusive surface. The FE analysis was performed by computer. Results: Φ ≤3 mm: stress on occlusal surface of crown was almost unchanged and mainly distributed in the loading area. Φ = 4 mm, stress appeared an obvious rise and reached the maximum, the stress concentration under vertical load was changed to the hole margin. In vertical loading, screw could remain at a relatively low stress level when diameter did not exceed 1 mm. No changes on other components was observed. Conclusion: SAH diameter of 1 mm is recommended when a cement-and screw-retained crown is used in posterior region.

Objective:To analyze the mechanism of Jindan Tablets, Xiaoyan Lidan Tablets and ursodeoxycholic acid in the treatment of gallstone and cholecystitis based on network pharmacology; To conduct a comparative analysis.Methods:The chemical components of Jindan Tablets, Xiaoyan Lidan Tablets and ursodeoxycholic acid and their drug targets were collected from Traditional Chinese Medicine Database and Analysis Platform (TCMSP). DAVID 6.8 database was used to search for the associated diseases of the drug targets. The disease targets of gallstone and cholecystitis were collected from GeneCards and other databases. The protein-protein interactions network was established based on the intersecting targets of three drugs and two diseases. KEGG enrichment analysis was performed based on the DAVID 6.8 database. Cytoscape 3.7.1 software was used to construct a complex network and topology analysis of component- target- disease between three drugs and diseases.Results:222 chemical components and 3 133 drug targets were collected for Jindan Tablets. 104 chemical components and 1 425 action targets were collected for Xiaoyan Lidan Tablets. 1 chemical component and 119 action targets were collected for ursodeoxycholic acid. The three drugs were associated with 31 diseases. 1 382 disease targets for gallstones and cholecystitis were collected. There were 237, 163 and 33 targets for gallstones and cholecystitis in the three drugs, of which 17 were shared by the three drugs and 20 were shared by Jindan Tablets and Xiaoyan Lidan Tablets. Based on the DAVID database, 113, 74 and 10 significant KEGG enrichment pathways were obtained for the three drugs respectively.Conclusions:The three drugs shared many targets and pathways in the treatment of gallstones and cholecystitis, which all had the function of regulating metabolism and inhibiting inflammatory response, while participating in apoptosis, oxidative stress and cancer pathology process. However, they had their own special effects, with Jindan Tablets favoring involving in the cancer process and inhibition of inflammation, and promoting angiogenesis. Xiaoyan Lidan Tablets and ursodeoxycholic acid focused on regulating cholesterol metabolism, and Xiaoyan Lidan Tablets also regulated steroid metabolism and inhibit inflammation, while ursodeoxycholic acid regulated bile acid metabolism.
