Objective To observe the effect of fasudil on cytoskeleton reconstruction in mouse podocytes induced by angiotensin Ⅱ (Ang Ⅱ),as well as to study the protective mechanism of fasudil in the pathological changes of podocytes.Methods Conditionally immortalized mouse podocytes were treated with Ang Ⅱ (10-7 mol/L).The podocytes were pre-incubated for 30 min or 60 min with various concentrations of fasudil (10-8,10-7,10-5 mol/L),then Ang Ⅱ (10-7 mol/L) were added and furtherincubated for 24 hours.The cytoskeleton distribution of podocyte as indicated by F-actin and synaptopodin was observed by fluorescence microscopy and Western blotting.At the same time,the activity of Rho signal pathway that mediates actin filament polymerization was analyzed by measuring the extent of Rho-associated coiled-coil-containing protein kinase 1 (ROCK-1) and myosin phosphatase-1 (MYPT1).Results Compared to the control group,AngⅡ disrupted the podocyte actin cytoskeleton and significantly decreased the expression of synaptopodin (P < 0.05),while fasudil stabilized the actin filaments,and improved the synaptopodin expression (P < 0.05).The expression enhancement of ROCK-1 and MYPT1 by Ang Ⅱ were reduced significantly by fasudil (P<0.05).Conclusion The cytoskeleton reconstruction of podocytes can be induced by Ang Ⅱ and inhibited by fasudil,which suggests that the protective effect of fasudil may be partially contributed to the Rho/ROCK signaling pathway.

OBJECTIVE:To study the feasibility of overflow dissolution method for evaluating the drug in vitro sustained re-lease performance. METHODS:Overflow dissolution method was established by simulating the drugs elimination in vivo. Using Nifedipine sustained-elease tablets(Ⅰ)from 2 different manufacturers as model drug A,B,concentration-time curve,cumulative release rate- time curve,release velocity-time curve of model drugs in release pool at 3 different overflow speed (0,1.50,3.00 mL/min)were investigated. RESULTS:When overflow speed was 0,the cumulative dissolution was consistent with that of the con-ventional dissolution method. As the overflow speed increased,cmax of drug A,B was decreased [A:(8.89±0.20),(5.21±0.04), (3.51±0.03)μg/mL;B:(7.62±0.05),(4.80±0.09),(2.89±0.04)μg/mL];cumulative release rate was increased [A:(85.47± 2.45)%,(94.29 ± 2.44)%,(96.04 ± 2.56)%;B:(73.28 ± 1.13)%,(78.46 ± 1.94)%,(82.50 ± 1.69)%] ;tmax was ahead (A:1.5,1.0,0.5 h;B:2.0,1.0,0.5 h). CONCLUSIONS:Overflow dissolution method has avoided the inhibition of too large drug concentration on drug release,making complete drug release and more accurate evaluation of in vivo sustained release performance of the preparation.

Objective To study the clinical significance of platelet, coagulation ,and fibrinolysis alteration in perioperative period in patients with different Child classifications of cirrhosis. Methods Alterations on the platelet count and the indices of coagulation and fibrinolysis in 17 cases of Child B class who underwent portal-systemic shunt, and 6 cases of Child C class who underwent portal-azygus vein disconnection were detected. Results Before operation,except the decrease in platelet count, there as no significant difference in the indices of other platelet function, coagulation and fibrinolysis in patients with Child B class compared with control group. While in patients with Child C class, the platelet count decreased, and GMP-140, FPA and D-dimer increased greatly. After operation, GMP-140 increased in patients with Child B class, while decreased in patients with child C class. The platelet count and factorⅧ:C in patients with Child C class decreased significantly compared with those with Child B class. Conclusions Operation may induce DIC in patients with Child C class, so it is necessary to determine the fibrinogen and factorⅧ:C during the operation.

OBJECTIVETo investigate whether the impairment of grafted liver after transplantation was induced by the same inflammatory cells in cold and warm ischemia.
METHODSMale SD rats were divided into two groups randomly, 24 grafted livers in each group were stored for 120 or 240 min at 4 degrees Centigrade Ringer's solution. Also male SD rats were divided into three groups, in which 24 grafted livers in each group were experienced warm ischemia ranged from 90, 120 to 150 min from non-heart-beating donor. The recipients were killed after 1, 3, 6, and 24 hours of transplantation for sample collection.
RESULTSAlong with the prolongation of cold and warm ischemia time, the serum ALT and AST levels were increased gradually after transplantation. Light microscopy showed some necroses in hepatocytes after 3 and 6 hours of transplantation in cold ischemia, and some neutrophilic infiltration in sinusoids. There were a large number of hepatocytes necroses after 3, 6 hours of transplantation in warm ischemia from non-heart-beating donor and a lot of lymphocytic infiltration in sinusoids. The findings in electron microscopy were as the same as those found in light microscopy, and the lymphocytes which infiltrated in sinusoids in warm ischemia were identified as T lymphocytes in electron microscopy.
CONCLUSIONSThe impairment of grafted livers after transplantation seems to be induced by two different inflammatory cells in cold and warm ischemia, that is, neutrophils mediate the cold ischemia-reperfusion, and T lymphocytes mediate the warm ischemia-reperfusion from non-heart-beating donor.

This paper discussed the pathogenesis and treatment ideas of recurrent angina pectoris after percutaneous coronary intervention (PCI) based on qi and blood vessels. It is believed that patients after PCI often have poor qi and blood circulation and damaged vessels and collaterals as the basis, and subsequently suffer from binding of phlegm and stasis, accumulated and sticky, which further lead to the vessels congested and blocked, qi and blood declined, and the body and functions of the heart damaged. Accordingly, in terms of the treatment principles, it has been proposed to regulate qi and transport blood, unblock and nourish vessels, dissolve phlegm and dispel stasis, direct turbidity downward and unblock collaterals, supplement qi and nourish the body, unblock vessels and rejuvenate meridians, by using self-made Tiaoqi Yunxue Formula (调气运血方), self-made Huoxue Jiangzhuo Formula (活血降浊方) and self-made Shenrong Tongmai Formula (参茸通脉方) in their modifications respectively, in order to provide reference for clinical diagnosis and treatment.

Osteoporotic proximal humeral fracture (OPHF) is one of the common osteoporotic fractures in the aged, with an incidence only lower than vertebral compression fracture, hip fracture, and distal radius fracture. OPHF, secondary to osteoporosis and characterized by poor bone quality, comminuted fracture pattern, slow healing, and severely impaired shoulder joint function, poses a big challenge to the current clinical diagnosis and treatment. In the field of diagnosis, treatment, and rehabilitation of OPHF, traditional Chinese and Western medicine have accumulated rich experience and evidence from evidence-based medicine and achieved favorable outcomes. However, there is still a lack of guidance from a relevant consensus as to how to integrate the advantages of the two medical systems and achieve the integrated diagnosis and treatment. To promote the diagnosis and treatment of OPHF with integrated traditional Chinese and Western medicine, relevant experts from Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine have been organized to formulate Expert consensus on the diagnosis and treatment of osteoporotic proximal humeral fracture with integrated traditional Chinese and Western medicine ( version 2024) by searching related literatures and based on the evidences from evidence-based medicine. This consensus consists of 13 recommendations about the diagnosis, treatment and rehabilitation of OPHF with integrated traditional Chinese medicine and Western medicine, aimed at standardizing, systematizing, and personalizing the diagnosis and treatment of OPHF with integrated traditional Chinse and Western medicine to improve the patients ′ function.
