Objective To observe he effects of new Tangshenkang on α-SMA and E-cadherin of human renal tubular epithelial cell HK-2 in high concentrations of glucose; To explore the mechanism of new Tangshenkang on the prevention and treatment of diabetic renal fibrosis. Methods The HK-2 cells were cultured and divided into control group, high glucose group, animal serum control group, new Tangshenkang low-, medium-, and high-dosage group. After medicine intervention, cell proliferation was tested by MTT assay, and contents of α-SMA and E-cadherin were observed by ELISA assay. Results Compared with control group, α-SMA of HK-2 cultured with high glucose was much notable, but the content of E-cadherin significantly decreased, with statistical significance (P<0.05). The content of α-SMA of HK-2 cultured with new Tangshenkang decreased, and the content of E-cadherin increased; cell proliferation was markedly inhibited in culture medium supernatant of HK-2 cells cultured with high glucose plus new Tangshenkang compared with only high glucose, with statistical significance. Conclusion New Tangshenkang can inhibit cell proliferation and epithelial-myofibroblast transdifferentiation of HK-2 cell induced by high glucose, and prevent the development of diabetic renal fibrosis to a certain extent.

ObjectiveTo explore the possible mechanism of pediatric tuina therapy in treating anorexia nervosa. MethodsTotally 120 children with anorexia nervosa were randomly divided into a tuina group and a medication group， with 60 cases in each group. Sixty healthy children undergoing physical examinations were recruited as the healthy control group. Children in the tuina group received traditional pediatric tuina therapy， while those in the medication group received orally chewed Jianwei Xiaoshi tablets. Each treatment course lasted for 7 days， with a 1-day interval between courses， and a total of 4 courses were administered. Before and after treatment， seven indicators including gastric motility frequency， gastric area， gastric area 30 minutes after drinking， anterior-posterior diameter and area during gastric fundus dilation， anterior-posterior diameter and area during gastric fundus contraction were measured using a color Doppler ultrasound diagnostic instrument in children from the healthy control group， tuina group， and medication group. Additionally， gastric emptying rate at 30 minutes， changes in anterior-posterior diameter and area during gastric fundus contraction， and changes in gastric area were compared. ResultsThis study ultimately included 60 healthy children in the control group， 59 children in the tuina group， and 51 children in the medication group. Compared with the control group at baseline， the gastric area and the anterior-posterior diameter and area during gastric fundus contraction increased， while the gastric emptying rate， gastric motility frequency， and changes in anterior-posterior diameter during gastric fundus contraction decreased in both the tuina group and medication group， with only a decrease in gastric area during gastric fundus contraction observed in the tuina group （P＜0.05）. Compared with baseline， after treatment， the gastric emptying rate， gastric motility frequency， and changes in anterior-posterior diameter and area during gastric fundus contraction increased in the tuina group， while the gastric area and area during gastric fundus contraction decreased 30 minutes after treatment； in the medication group， gastric motility frequency and changes in anterior-posterior diameter during gastric fundus contraction increased， while the area during gastric fundus contraction decreased （P＜0.05 or P＜0.01）. Compared with the medication group after treatment， the gastric area decreased 30 minutes after treatment， while the gastric emptying rate and gastric motility frequency increased （P＜0.05）. ConclusionThe possible mechanism of pediatric tuina therapy in treating anorexia nervosa is to promote gastric motility and gastric emptying， thereby improving gastrointestinal dysfunction in children.

Objective Evaluate the performance of the encephalon state index(ESI)in depth of anesthesia monitoring during clinical surgery,compared with the bispectral index(BIS).Methods ESI and BIS data were collected from 60 patients in a single-center clinical trial to compare their efficacy in measuring the depth of anesthesia.Results Consistency analysis revealed mean differences and standard deviations of-0.18±5.42 and-0.11±6.51 between ESI and BIS for awake and anesthetized states,respectively.Correlation analysis showed a correlation coefficient of 0.92 throughout the operative period.Prediction probability analysis indicated that both ESI and BIS had prediction probabilities of 0.97,effectively predicting anesthesia status.Conclusion ESI and BIS show good equivalence in monitoring depth of anesthesia during clinical surgery,which meet the requirements of clinical anesthesia.
