The overall concept is the core theory of traditional Chinese medicine ( TCM ) diagnosis and treat-ment system. During the process of building TCM effect evaluation on coronary heart disease (CHD), with the defined connotation and extension of heart diseases , except the consideration on its clinical symptoms , TCM four diagnosis and various current modern cardiovascular disease diagnostic methods should be organically com-bined according to the original macro basis . The micro quantitative evaluation is given on therapeutic effect of disease treatment in order to construct the complete TCM effect evaluation system.

AIM: To study urinary concentration of aquaporin-2 water channel protein(AQP2) at different stages of chronic heart failure(CHF) rats and its relation to hyponatremia. METHODS: Male Sprague-Dawley rats(200～250 g) underwent either a left coronary artery ligation (a model of CHF) or a sham-operation. At different stage after surgery, urinary AQP2 concentration was measured by Western blot. 24-hours urine volume, serum sodium and urine osmolality were measured at the same time. RESULTS: There were two peaks of urinary excretion of AQP2 in severe heart failure rats model: one was the third day after operation, the other was the 9th week. Serum sodium and urine osmolality were significantly different in CHF rats as compared with sham-operated rats. Seven weeks after surgery, urinary AQP2 concentration was increased significantly insevere CHF rats compared with the mild ones and the control ones(365%?103% vs 179%?81% and 99%?48%, P

Objective To observe the protective and anti-inflammatory effects of Emodin and Geniposide compatibility on the intestinal mucosal barrier function damage in rats with systemic inflammatory response syndrome(SIRS).Methods Male Sprague-Dawley(SD)rats aged 6-8 weeks were randomly divided into normal control group,model group,Emodin group,Geniposide group,Emodin and Geniposide compatibility group(compatibility group),and Ulinastatin group.The SIRS model in rats was established by abdominal injection of yeast polysaccharide.The Emodin,Geniposide,Ulinastatin,and compatibility groups received administration immediately and 12 hours after the injection of yeast polysaccharide.After 24 hours of modeling,the contents of D-lactate(D-LA),diamine oxidase(DAO),endotoxin(ET),tumor necrosis factor-α(TNF-α),interleukins(IL-1β,IL-6,IL-10)in the serum of each group were measured;The small intestine was taken for histopathological examination,and the positive protein expression levels of nuclear factor-κB p65(NF-κB p65)and Toll-like receptor 4(TLR-4)in the small intestine tissue were determined by immuno histochemistry.Results Compared with the normal control group,the levels of D-LA,DAO,ET,TNF-α,IL-1β,IL-6 and IL-10 in the serum of the model group were significantly increased[D-LA(μmol/L):99.11±11.93 vs.36.94±1.92,DAO(U/L):5 018.80±759.00 vs.2 253.23±372.40,ET(μg/L):0.36±0.04 vs.0.15±0.02,TNF-α(ng/L):66.61±20.88 vs.9.47±0.78,IL-1β(ng/L):63.73±7.64 vs.25.86±5.90,IL-6(ng/L):392.00±56.47 vs.111.17±36.22,IL-10(ng/L):41.90±8.12 vs.19.75±1.54,all P<0.05],histopathological observations showed that the small intestine mucosa was significantly swollen,the arrangement of mucosal epithelial cells was disordered,and there was cell shedding,increased infiltration of inflammatory cells in the intestinal mucosa,decreased goblet cells,loose and congested lamina propria;the positive protein expression of TLR-4 and NF-κB in the small intestine tissue was enhanced[TLR-4 positive protein expression(A value):0.59±0.08 vs.0.27±0.04,NF-κB positive protein expression(A value):0.65±0.07 vs.0.30±0.06,both P<0.05].Compared with the model group,the levels of D-LA,DAO,and ET in the serum of the Emodin group,Geniposide group,Ulinastatin group,and compatibility group were significantly decreased[D-LA(μmol/L):67.49±8.32,69.08±6.76,69.17±5.63,58.16±7.12 vs.99.11±11.93,DAO(U/L):3 659.38±563.90,3 713.29±354.70,3 575.30±444.4,3 087.01±227.50 vs.5 018.80±759.0,ET(μg/L):0.27±0.04,0.24±0.03,0.23±0.03,0.20±0.02 vs.0.36±0.04,all P<0.05],and the contents of pro-inflammatory factors TNF-α,IL-1β,and IL-6 were significantly decreased[TNF-α(ng/L):44.34±10.63,39.23±11.74,35.80±11.49,28.74±9.56 vs.66.61±20.88,IL-1β(ng/L):50.30±8.22,46.74±5.10,48.25±5.16,40.84±5.02 vs.63.73±7.64,IL-6(ng/L):299.27±50.65,263.98±37.62,281.84±63.24,216.72±38.90 vs.392.00±56.47,all P<0.05].The levels of serum anti-inflammatory factor IL-10 were significantly increased(ng/L:92.63±32.83,87.34±30.79,71.66±16.82,133.70±39.40 vs.41.90±8.12,all P<0.05).The pathological changes in the intestinal tissue of the Emodin group,Geniposide group,compatibility group,and Ulinastatin group were reduced,and the positive expressions of NF-κB p65 and TLR-4 proteins in the small intestine tissue were significantly decreased[TLR-4 positive protein expression(A value):0.49±0.03,0.47±0.08,0.36±0.08,0.42±0.06 vs.0.59±0.08,NF-κB p65 positive protein expression(A value):0.50±0.06,0.49±0.07,0.42±0.06,0.46±0.09 vs.0.65±0.07,all P<0.05].Compared with the Emodin group and Geniposide group,the serum D-LA,DAO,ET,TNF-α,IL-1β,and IL-6 in the compatibility group were significantly decreased,the serum IL-10 level was significantly increased,the pathological changes in the intestinal tissue were reduced,and the expression levels of NF-κB p65 and TLR-4 in the small intestine tissue were significantly decreased(all P<0.05).Conclusions Emodin and Geniposide can help relieve SIRS induced by yeast polysaccharide,and their effect is related to protecting the intestinal mucosal barrier and inhibiting the inflammatory response.When combined,they exhibit a synergistic effect.

Objective To evaluate the effect of conversion from mycophenolic acid (MPA) to mizoribine (MZR) in renal transplant recipients with gastrointestinal tract (GI) symptoms.Methods A total of 355 renal transplant recipients with GI symptoms caused by MPA administration were enrolled from April 2015 to March 2017 in 25 different renal transplant centers in China.The symptomatic improvement of GI before (baseline) and after conversion to MZR (1,2,4 weeks) was assessed by each item of GI symptoms indication.In addition,the efficacy and safety of the conversion therapy during 12 months were determined.Results Patients showed improvement in GI symptoms including diarrhea,abdominal pain,abdominal distention and stomachache after conversion to MZR 1,2,4 weeks (P＜0.05).In patients with different severity of diarrhea,conversion to MZR therapy significantly improved diarrhea (P＜0.05).During 12 months,no patient experienced clinical immune rejection.We did not observe any infections,leucopenia and other serious side effects.Conclusion MZR could markedly improve GI symptoms caused by MPA administration in renal transplant recipients.

The positive human leukocyte antigen (HLA) antibody present in kidney transplant recipients affects both surgery and rejection, and also affects the long-term survival of the transplanted kidney. During the third kidney transplant, bilateral axillary fossa and iliac vessel were destroyed. It was very difficult for selection or separation of surgical vessels because the adhesions and scar formation was easy to damage blood vessels and intestinal tubes. A case with strong positive HLA antibody undergoing the third kidney transplant in our hospital was successfully solved the problems, such as less transplant space and vascular scar adhesion. Rituximab, rabbit anti-human thymocyte immunoglobulin, and methylprednisolone treated-antibodies were used in the operation. The immune function test was used to develop individualized treatment after the operation. The postoperative creatinine and urine volume tended to be stable, and the 16-month follow-up renal function was good.

Ubiquitination is one of the most major post-translational modifications playing important role in regulation of intra-cellular proteins' stability, degradation, localization and biological activity. However, these proteins are difficult to be detected due to their low abundance, short half-life. In this study, ubiquitin-binding domains (UBDs) were constructed to purify the ubiquitinated proteins from Hep3B cells. Ubiquitinated proteins and sites were detected by LC-MS/MS. A total of 1 900 potential ubiquitinated proteins were identified. Among them, 158 ubiquitinated sites were identified, belonging to 102 proteins. Bioinformatics analysis revealed that the enriched pathways of ubiquitinated proteins were closely related to tumor occurrence and development. The dysfunction of ubiquitin-proteasome has a high correlation with cell signaling and extracellular matrix changing in tumor cells.

OBJECTIVE: To assess the value of Ploton silver staining and phalloidin-iFlour 488 staining in observation of the morphology of osteocyte dendrites of mice at different developmental stages. METHODS: The humerus and femurs were harvested from mice at 0 (P0), 5 (P5), 15 (P15), 21 (P21), 28 (P28), and 35 days (P35) after birth to prepare cryo-sections and paraffin sections. HE staining of P35 mouse femur sections served as a reference for observing osteocytes in the trabecular bone and cortical bone. The humeral sections at different developmental stages were stained with Ploton silver staining to observe the morphology of osteocytes and canaliculi, and the canalicular lengths in the cortical and trabecular bones of the humerus of the mice in each developmental stage were recorded. The cryo-sections of the humerus from P10 and P15 mice were stained with phalloidin iFlour-488 to observe the morphology of osteocytes and measurement of the length of osteocyte dendrites in the cortical bone. RESULTS: In the trabecular bone of the humerus of P0-P15 mice, Ploton silver staining only visualized the outline of the osteocytes, and the morphology of the canaliculi was poorly defined. In P21 or older mice, Ploton silver staining revealed the morphology of the trabecular bone osteocytes and the canaliculi, which were neatly arranged and whose lengths increased significantly with age (P21 CONCLUSIONS Mouse osteocyte dendrites elongate progressively and their arrangement gradually becomes regular with age. Ploton silver staining can clearly visualize the morphology of the osteocytes and the canaliculi in adult mice but not in mice in early stages of development. Phalloidin iFlour-488 staining for labeling the cytoskeleton can be applied for mouse osteocytes at all developmental stages and allows morphological observation of mouse osteocytes in early developmental stages.
