Objective To observe the influence of Kuailvning capsule(KLN)and its drug serum on the concentration of Ca2 + in rat ventricular muscle cells.Methods SD rats were randomly divided into five groups:the control group,serum control group,KLN high -dose group,KLN medium -dose group and KLN low -dose group,six mice in each group.The rat ventricular myocytes were separated by enzymatic hydrolysis.The influence of KLN and its drug serum on the concentration of Ca2 + in rat ventricular muscle cells were observed by Fluo -3 /AMprobe.Results The mean fluorescence intensity of cytosolic Ca2 + in the KLN high -dose group,KLN medium -dose group and KLN low -dose group after 50s,100s,150s,200s,250s were [(18.75 ±1.55),(16.69 ±0.93),(17.76 ±1.26)], [(25.47 ±1.118),(17.86 ±1.49),(17.81 ±1.13)],[(29.05 ±1.31),(20.14 ±1.73),(18.26 ±1.37)], [(35.21 ±1.33),(23.19 ±0.97),(18.18 ±1.46)],[(41.08 ±1.21),(26.34 ±1.69),(17.91 ±1.01)], which were higher than those in the control group(F =5.556,7.007,8.816,10.208,12.232,all P <0.01 ).The mean fluorescence intensity of cytosolic Ca2 + in the KLN high -dose group after 50s,100s,150s,200s,250s were (17.85 ±1.69),(18.95 ±1.73),(21.85 ±1.39),(23.01 ±1.48),(24.07 ±1.42),which were higher than those in the serum control group(t =3.642,4.406,6.074,7.402,8.625,all P <0.01 ).The mean fluorescence intensity of cytosolic Ca2 + in the KLN medium -dose group after 100s,150s,200s,250s were (18.01 ±1.42), (18.76 ±1.22),(19.73 ±1.37),(21.04 ±1.16),which were higher than those in the serum control group(t =3.902,4.033,4.126,4.326,all P <0.01).There were no statistically significant difference between the KLN low -dose group and the serum control group(P >0.05).Conclusion KLN drug serum can promote myocardial cell spon-taneous extracellular calcium influx,the mechanism of KLN antiarrhythmic effect may be related to the Ca2 + channel.

Chondroitin sulfate proteoglycans ( CSPGs) is one kind of proteins that covalently bind with chondroitin sulfate.CSPGs play important roles in the growth and development of the central nervous system and the pathological reaction of nervous injury.This article reviews the functional and mechanism studies of CSPGs in the repair of nerve system injury.

Objective To evaluate the level of MMP-2 and COX-2 Protein in bladder transitional cell carcinoma tissue and explore their relationships. Methods A total of 42 patients with bladder transitional cell carcinoma, including Ta-T1 (n=18), T2-T4 (n=24), G1(n=12), G2 (n=19), G3 (n=11), metastasis (n=26) and without metastasis (n=16), were enrolled in the study. Eight normal bladder tissues were selected as control group. Western blotting was performed todetect the mRNA level of MMP-2 and COX-2. Results The relative COX-2 protein level of Ta-T1 (0.729±0.458), T2-T4 (1.248±0.425), G1 (0.61±0.486), G2 (1.055±0.406), G3 (1.422±0.341) were all higher than that of the control group significantly (0.31±0.149, t = 3.56, 4.13; F = 5.98, P ＜0.05). The relative MMP-2 protein level of Ta-T1 (0.844±0.345), T2-T4 (1.458±0.463), G1 (0.971 ±0.370), G2(1.445±0.378), G3 (1.755±0.387) were all higher than that of the control group (0.460±0.213, t = 3.91, 4.83;F = 6.35, P ＜0.05). The COX-2 and MMP-2 protein level in tumor tissues with and without metastasis were 1.246±0.426 vs 0.668±0.421, 1.430±0.461 vs 0.814±0.341, t = 5.89, 6.27, P ＜0.01, respectively. The level of COX-2 protein was positively correlated with MMP-2 positively (r =0.48, P ＜0.01). Conclusion MMP-2 and COX-2 protein are highly expressed in bladder transitional cell carcinoma tissue and their expression is positively correlated with the malignant degree. MMP-2 and COX-2 might play a synergetic role in the carcinogenesis of bladder transitional cell carcinoma.

Objective To investigate the treatment of septic shock(SS) from upper urinary obstruction(UUO). Methods Continuous veno-venous haemofiltration(CVVH) combined with surgical method was applied to 42 SS patients from UUO. Their general conditions, liver and kidney functions, APACHE Ⅱ, therapeutic intervention scorisystem(TISS), multiple organ dysfunction syndrome (MODS), complication rate and main outcomes were analysed comparing with traditional therapies groups(n=30). Results Compared with those traditional therapies, the APACHEⅡ , MODS and TISS score decreased (P＜0.05). Thirty-seven out of 42 patients survived and the survival rate was 88.0% during ICU. Conclusion CVVH combined with surgical methods may effectively decrease the incidence of complications and mortality of SS from UUO, and the mechanism may be related to the remove of mediators of inflammation.

Objective To observe the expression levels of kidney injury molecule-1(KIM-1) in renal tissues of ischemia-reperfusion rats,and to explore the value in the diagnosis of acute kidney injury.Methods Rats were randomly divided into two groups,control(CON) group (n=64) and acute kidney ischemia reperfusion injury (AIKI) group (n=64).Rats were sacrificed following reperfusion 2h,6h,24h,48h,72h,1 week (w),2 w,and 4 w.The changes of morphology were checked on HE staining sections under light microscope.The extent of tubulointerstitial injury was determined by Sayhan classification.The distribution and expression of KIM-1 in renal tissue were observed by immunohistochemistry and Western blotting.Serum samples were collected and serum creatinine measurement was performed at different reperfusion time points.Results (1) Compared with the CON group,the renal tubulointerstitial injury scores of AIKI group were significantly higher at all times after reperfusion (P<0.01).(2) The expression of KIM-1 was consistent with the tubulointerstitial injury.The positive correlation between KIM-1 and the tubulointerstitial injury scores was significant(r=0.887,P=0.003).(3) Compared with the CON group,serum creatinine in AIKI group was significant higher at 2h,6h,24h,48h,72h after reperfusion (P<0.05).Serum creatinine had no correlation with the damage of renal tubulointerstitial.Conclusion The expression of KIM-1 increases significantly in renal ischemia reperfusion injury,and it is consistent with the tubulointerstitial injury.Compared with serum creatinine,KIM-1 may be a more accurate biomarker of renal damage.

Based on recent studies which have shown that gut microbiota plays an important role in the pathogenesis of non-alcoholic fatty liver disease (NAFLD), the article elaborates on the relationship of NAFLD with intestinal endotoxemia, short-chain fatty acids, bile acid metabolism, and endogenous ethanol. By illustrating the author′s research progress in the relationship between traditional Chinese medicine (TCM) regulation of gut microbiota and NAFLD treatment, the article proposes that this approach is not only a clinical practice of TCM in the modern era, it may also become a new strategy in the treatment of NAFLD.

Objective:To explore the effect of traditional Chinese medicine fumigation and washing on the clinical indicators of elderly patients with distal radius fractures after small splint fixation.Methods:From November 2015 to November 2018, 180 elderly patients with fracture of the distal radius in Ningbo Hospital of Traditional Chinese Medicine were selected, and they were divided into control group and observation group according to the random digital table method, with 90 cases in each group.The two groups were given manual reduction and small splint fixation treatment, and the observation group was treated with traditional Chinese medicine fumigation on the basis of the control group therapy.The related inflammatory cytokines in patients plasma and serum viscosity(TNF-α, IL-1, IL-6) were detected, and the clinical curative effect and adverse reactions were observed.Results:Before treatment, there were no statistically significant differences in plasma viscosity and blood inflammatory factors(TNF-α, IL-1, IL-6) between the two groups( t=-0.171, -0.126, 0.483, 0.459, all P>0.05). After treatment, the above indicators in the two groups were significantly lower than those before treatment(observation group: t=38.970, 14.684, 72.258, 53.612; control group: t=20.098, 19.045, 33.962, 34.822, all P<0.05), which in the observation group were lower than those in the control group ( t=-30.239, -7.043, -31.815, -10.359, all P<0.05). The total effective rate of the observation group was 88.88%(80/90), which was higher than 71.11%(64/90) of the control group, the difference was statistically significant between the two groups(χ2=8.889, P<0.05). Conclusion:For the elderly patients with distal radius fracture, the combination of reduction and small splint fixation and fumigation with traditional Chinese medicine can significantly improve the hemorheology of the patients and reduce the contents of inflammatory factors in the body, with significant efficacy and no adverse reactions, which is worthy of clinical application.
