Aim To investigate the effect on antagonism of benthiactzine and atropine against the function of muscarinic acetylcholine receptors by desensitization of nicotinic acetylcholine receptors. Methods The whole cell recording configuration of patch-clamp technique was used and the cell model was rat SCG neurons. To identify antagonists' antimuscarinic effect, mAchRs mediated IM-inhibition was measured and nicotine and oxotremorine were used. Results After de sensitization of nAChRs,the antimuscarinic effect ofboth benthiactzine and atropine decreased compared to the normal condition. The decreased antimuscarinic effect of benthiactzine was weaker than that of atro-pine. The antimuscarinic effect of both benthiactzine and atropine recovered gradually with the recovery of nAChRs from desensitization. Conclusion Desensiti-zation of nAChRs weakens the antagonists' antimuscarinic effect.

Inner fistula by abdomino-back anastomosis of cephalic vein to radial artery was erformed in 86 patients with hemodialysis (test group) and end-to side arteriovenous anastomosis was performed in 85 cases (control group).There were no significant differences in postoperative anastomotic blood flow and vascular complications between two groups (P ＞ 0.05);however the average time consuming for operation in test group was shorter than that in control group (36 min vs.75 min,P ＜ 0.01).The minimally invasive abdomino-back anastomosis is a desired arteriovenous fistula method for hemodialysis patients.

Objective To summarize the experience of long-term survival of the patients under- going orthotopic heart transplantation.Methods Heart transplantation was performed on 2 cases of dilated cardiomyopathy and one case of Keshan disease.Before operation,pulmonary artery pressure was 42-53 mm Hg(5.60-7.07 kPa)and pulmonary vascular resistance 5.6-7.0 wood.The body weight difference between donors and receptors was 10%-15%.There were three same antigens in HLA zygosity experiment for all of three patients.Two cases were subjected to standard heart trans- plantation and one case to whole heart transplantation.All the atriums and big vessels were sutured by evting suture method.Cyclosporin A,azathioprine and corticosteroid were used to prevent patients from rejection.Results Survival time of 3 patients was 13 years and 10 months,12 years and 10 years and 3 months.Heart functions of three patients were NYHAⅠand all of 3 patients are living and working commonly.Six,3 and 1 rejection(s)occurred in 3 patients respectively and cured by appro- priate treatment.Electrocardiogram revealed that case 1 and case 2 had two P waves and case 3 sinus rhythm.Ultrasonic cardiogram showed that in case 1 and case 2,the left and right atriums were enlarged and tricuspid valve had slight backstreaming,and in case 3,all of the cardiac chambers were normal and had no backstreaming of tricuspid valve and mitral valve.No abnormal findings were found in 3 cases by 4-9 times of coronary arteriongraphy.Conclusion The important factors for the patients' long-term survival after heart transplantation include the choice of appropriate donors and acceptors, protection of donors' hearts,selection of appropriate operations and suture methods,rational use of im- munosuppressants and prevention of cardiac allograft vasculopathy.

Objective To investigate the effects of CD24 on CCl4-induced murine liver fibrosis and to analyze the possible molecular mechanism.Methods Wild type (WT) and CD24 knockout (CD24-/-) C57BL/6 mice were treated with CCl4 through intraperitoneal injection.Levels of ALT in serum samples were detected and liver tissues were stained with hematoxylin and eosin (HE) to assess liver tissue injury.Sirius Red staining was used to observe liver fibrosis.Real-time PCR was performed to detect the expression of α-SMA (α-smooth muscle actin), Col1a1 (Collagen, typeⅠ, alpha 1), TGF-β1 (transforming growth factor-β1) and CD24 at mRNA level in liver tissues.Western blot was performed to analyze the expression of α-SMA and Col1a1 at protein level.Flow cytometry analysis was used to detect the macrophages in liver tissues.ELISA was used to detect the expression of TGF-β1 in the culture supernatants of M1 and M2 macrophages.Results The expression of CD24 at both mRNA and protein levels were up-regulated in mice with CCl4-induced liver fibrosis.HE staining showed that liver inflammation in CD24-/-mice was more severe than that in WT mice after treated with CCl4.Sirius Red staining of paraffin-embadded liver sections revealed that compared with WT mice, CD24-/-mice presented with more severe liver fibrosis.Moreover, α-SMA and Col1a1, indicators of liver fibrosis, in CD24-/-mice were significantly higher than those in WT mice.Flow cytometry analysis showed that murine hepatic macrophages significantly increased in CD24-/-mice than in WT mice following CCl4 treatment.Real-time PCR analysis also confirmed that significantly enhanced expression of TGF-β1 at mRNA level in liver tissues was observed in CD24-/-mice than in WT mice.TGF-β1 secreted in the culture supernatant of M2 macrophages derived from CD24-/-mice group was more than that of the WT mice group.No significant difference in TGF-β1 secretion in culture supernatant of M1 macrophages was observed between the two groups.Conclusion Taken together, these data suggest that CD24 plays an important role in attenuating CCl4-induced chronic inflammation and hepatic fibrosis in mice.The mechanism of CD24 in alleviating liver fibrosis might be through regulating intrahepatic macrophages, inhibiting the secretion of TGF-β1 by M2 macrophages and suppressing the activation of hepatic stellate cells.

BACKGROUND: The complications of systemic inflammatory response syndrome (SIRS) include acute lung injury, acute kidney injury, shock, and multiple organ dysfunction syndrome (MODS). In recent years, how to clear inflammatory mediators has become a hot topic in critical care medicine. Researchers hypothesize that continuous blood purification (CBP) can effectively eliminate a variety of inflammatory mediators which participate in the occurrence of MODS and adjust the immune imbalance. This study aimed to observe the effects of CBP in MODS patients. METHODS: In this retrospective clinical study, a total of 38 MODS patients, 18 males and 20 females, were enrolled. After conventional therapy, all the patients received CBP. Biochemistry, blood gas analysis, oxygenation index, mean arterial blood pressure (MAP), acute physiology and chronic health evaluation (APACHE) II scores were monitored. RESULTS: After CBP, the vital signs of patients were rapidly stable, and electrolyte disorders and acid-base imbalance were corrected. Renal function, blood gas, oxygenation index were all improved. MAP was increased, and APACHE II score was significantly decreased. All patients had good tolerance, stable hemodynamics, and no obvious adverse reaction on CBP compared with pre-CBP. CONCLUSION: CBP can effectively clean toxins, correct electrolyte acid-base balance, and improve systemic inflammatory response syndrome and the organ function of MODS patients.

Through potted inoculation test at room temperature and indoor analysis, the photosynthetic parameters and physiological and biochemical indexes of Paris polyphylla var. yunnanensis were observed after 28 arbuscular mycorrhizal (AM) fungi were injected into the P. polyphylla var. yunnanensis growing in a sterile soil environment. The results showed that AM fungi established a good symbiosis with P. polyphylla var. yunnanensis. The AM fungi influenced the photosynthetic parameters and physiological and biochemical indexes of P. polyphylla var. yunnanensis. And the influences were varied depending on different AM fungi. The application of AM fungi improved photosynthesis intensity of P. polyphylla var. yunnanensis mesophyll cells, the contents of soluble protein and soluble sugar, protective enzyme activity of P. polyphylla var. yunnanensis leaf, which was beneficial to resist the adverse environment and promote the growth of P. polyphylla var. yunnanensis. Otherwise, there was a certain mutual selectivity between P. polyphylla var. yunnanensis and AM fungi. From the comprehensive effect of inoculation, Racocetra coralloidea, Scutellospora calospora, Claroideoglomus claroideum, S. pellucida and Rhizophagus clarus were the most suitable AM fungi to P. polyphylla var. yunnanensis when P. polyphylla var. yunnanensis was planted in the field.

In this paper, the action of suet oil in the preparation of self-assembled micelles of the active flavonoids in Epimedium in the simulated human environment was researched. Twelve suet oil samples were collected from different growing areas and different positions of sheep or goat to simulate the formation of micelles. Then the effects of the fatty acids in suet oil on the preparation of self-assembled micelles were studied furthermore. The results showed that the micelles had a dispersed state and spherical smooth surface. To compare the diameter, potential, encapsulation efficiency and drug loading of the 12 batches micelles, the micelles prepared by the suet oil from Qinghai were more stable and had a higher encapsulation efficiency. The fatty acids in suet oil could promote the formation of self-assembled micelles, but the whole suet oil had a better effect. Above all the study, we confirmed that the suet oil promoted the formation of self-assembled micelles of the flavonoids in Epimedium, it laid foundation for further research about increasing the efficacy of Epimedium and improved the absorption of the active flavonoids in Epimedium.
