Objective To investigate the effects of Pollen Typhae total flavone (PTF) on INS-1 pancreaticβcell damage induced by palmitic acid ( PA) . Methods INS-1 pancreatic β cells were given long-term induction with PA to establish the impaired cell model, and then were intervened with PTF. Cell viability was determined by tetrazolium salt ( XTT) colorimetry. Results PA impaired the viabilities of INS-1 pancreatic β cells in concentration- and time-dependent manner, and PTF improved the impairment of INS-1 pancreatic β cells induced by PA in concentration -dependent manner. Moreover, PTF showed better improvement on the impairment when the INS-1 pancreatic β cells were impaired more seriously by PA. Conclusion PTF has effects on ameliorating the impairment of INS-1 pancreaticβcells induced by PA for long time.

BACKGROUND: Above curative dose, there is a dose-dependent correlation of the survival rate of fat transplantation with vascular endothelial growth factor (VEGF), the curative dose of VEGF determines the tissue volume of transplanted fat. OBJECTIVE: To investigate the changes of the blood supply rebuilding and the survival rate of the fat transplant in the microenvironment of continuous infusion of VEGF using osmotic pump. DESIGN, TIME AND SETTING: A cellular morphology observational experiment was performed from September 2007 to October 2008 in Department of Plastic Surgery at the Affiliated Hospital of Guangdong Medical College. MATERIALS: Ninety healthy SD rats were used to establish autologous fat transplantation models. Human VEGF was produced by American ONCOGEN Corporation. Type Alzet2002 mini-osmotic pump was produced by American Alzet Corporation. METHODS: Ninety rats were equally divided into 3 groups randomly. The operation control group was only processed into autologous fat transplantation; Experimental control group received autologous fat transplantation and continuous infusion of 2 000 ?L physiological saline using osmotic pump at a speed of 0.5 ?L/h for 14 days; Experimental group received autologous fat transplantation and continuous infusion of 2 000 ?L physiological saline containing 1 ?g VEGF using osmotic pump at a speed of 0.5 ?L/h for 14 days. MAIN OUTCOME MEASURES: At the 7th, 14th, 28th, 42nd, 64th days postoperation, the graft’s survival volumes were measured using mini-scale test tube; the cell morphology changes were observed with hematoxylin-eosin stain; The newly born microvessels on experimental group and control groups were researched with immunohistochemistry staining. RESULTS: At 14 days postoperation, the graft’s survival volumes of experimental group was higher than operation control group and experimental control group (P 0.05). At each time point, the vascular density of the fat transplant in the experimental group was higher than that in other groups (P 0.05). CONCLUSION: VEGF can speed up vasifaction and raise fat graft survival significantly.

Objective To investigate the effect of sorafenib in ameliorating renal fibrosis and its possible mechanisms.Methods Rats were subjected to unilateral ureteral obstruction (UUO ) and intragastrically administered sorafenib.NRK-52E cells were treated with transforming growth factor-β1 (TGF-β1)and sorafenib. HE staining was used to visualize renal fibrosis.α-SMA and E-cadherin expressions in kidney tissue and NRK-52E cells were performed using immunofluorescence.The cell cycle of NRK-52E cells was determined by flow cytometry analysis.Smad3 and p-Smad3 protein expressions in NRK-52E cells were detected by Western blot analysis. Results HE staining showed that kidney interstitial fibrosis,tubular atrophy,and inflammatory cell infiltration in the sorafenib-treated UUO groups were significantly decreased compared with the vehicle-treated UUO group (P<0.05).Compared with those in UUO and TGF-β-stimulated NRK-52E groups,the expression of a-SMA decreased but E-cadherin expression increased in the UUO kidneys and NRK-52E cells of the sorafenib-treated groups (P<0.05).After 24 h stimulation with TGF-β1 5 ng/mL,the number of cell cycles arrested in G0/G1 phase was significantly increased and the number of cells that entered G2 ,S phase decreased (P<0 .0 5 ).Compared with that in TGF-β-stimulated NRK-52E groups, p-Smad3 decreased in the sorafenib-treated groups (P<0.05). Conclusion Our results suggest that sorafenib may be useful for the treatment of renal fibrosis through suppressing TGF-β/Smad3 signaling.

OBJECTIVE To establish the fingerprint of Qiguiling mixture and the method for the content determination of 4 kinds of active components such as calycosin-7-glucoside， so as to control the quality of Qiguiling mixture. METHODS The fingerprints of 12 batches of Qiguiling mixture were established by HPLC. SPSS 25.0 software was used for cluster analysis and principal component analysis， and SIMCA 14.1 software was used for orthogonal partial least squares-discriminant analysis. The variable importance in projection （VIP） value greater than 1.0 was used as the index to screen the differential components. The contents of calycosin-7-glucoside， glycyrrhizin and glycyrrhizic acid were calculated by the quantitative analysis of multi- components by single marker （QAMS） with hesperidin as the internal reference， and the results were compared with external standard method. RESULTS In the fingerprints of 12 batches of samples， 17 common peaks were identified， and the similarities were more than 0.940. A total of 4 common peaks were identified， which were calycosin-7-glucoside （peak 6）， glycyrrhizin （peak 8）， hesperidin （peak 12）， and glycyrrhizic acid （peak 17）. The 12 batches of samples could be clustered into two categories， S4， S7-S9 and S11-S12 were clustered into one category， and the other batches of samples were clustered into one category. The cumulative variance contribution rate of the six principal components was 85.840%， and VIP values of peaks 15， 14， 4， 8 （glycyrrhizin） and 9 were all greater than 1.0. The relative error between the results of QAMS and external standard method was less than 5% （n＝3） for the contents of calycosin-7-glucoside， glycyrrhizin and glycyrrhizic acid. CONCLUSIONS Established HPLC fingerprint and content determination method in this study can be used for quality control of Qigiling mixture. Five components such as glycyrrhizin are the differential components.

Periarticular fracture of the shoulder is a common type of fractures in the elderly. Postoperative adverse events such as internal fixation failure, humeral head ischemic necrosis and upper limb dysfunction occur frequently, which seriously endangers the exercise and health of the elderly. Compared with the fracture with normal bone mass, the osteoporotic periarticular fracture of the shoulder is complicated with slow healing and poor rehabilitation, so the clinical management becomes more difficult. At present, there is no targeted guideline or consensus for this type of fracture in China. In such context, experts from Youth Osteoporosis Group of Chinese Orthopedic Association, Orthopedic Expert Committee of Geriatrics Branch of Chinese Association of Gerontology and Geriatrics, Osteoporosis Group of Youth Committee of Chinese Association of Orthopedic Surgeons and Osteoporosis Committee of Shanghai Association of Chinese Integrative Medicine developed the Chinese expert consensus on the diagnosis and treatment of osteoporotic periarticular fracture of the shoulder in the elderly ( version 2023). Nine recommendations were put forward from the aspects of diagnosis, treatment strategies and rehabilitation of osteoporotic periarticular fracture of the shoulder, hoping to promote the standardized, systematic and personalized diagnosis and treatment concept and improve functional outcomes and quality of life in elderly patients with osteoporotic periarticular fracture of the shoulder.
