Objective:To explore the clinical effect of multidisciplinary cooperation model in the prevention of acquired dysphagia in ICU.Methods:A multidisciplinary team was set up to collect 118 patients in Neurosurgery ICU of our hospital as the research object. The patients were divided into the experimental group and the control group, 59 cases in each group. The control group implemented the routine nursing measures of ICU, and the experimental group implemented the multidisciplinary cooperative nursing mode. The incidence of ICU acquired swallowing disorders (ICU-ASD) and complications of the two groups were compared.Results:There was no significant difference between the two groups in the incidence of swallowing dysfunction 24 hours after tracheal extubation ( P>0.05). The incidence of swallowing dysfunction 48 hours and 72 hours after tracheal extubation in the control group was 11.86% (7/59) and 16.95% (10/59) respectively, while the test group was 1.69% (1/59) and 3.39% (2/59) respectively. The difference was statistically significant ( χ 2values were 4.827 to 7.230, P< 0.05 or 0.01); the incidence of aspiration, aspiration pneumonia and malnutrition in the control group were 11.86% (7/59), 10.17% (6/59) and 8.47% (5/59), respectively, while the test group were 1.69% (1/59), 0 and 0, respectively, with statistically significant difference ( χ 2value was 4.827, P< 0.05). Conclusion:Multidisciplinary cooperation model can effectively prevent the incidence of ICU-ASD, and ultimately reduce the incidence of complications.

Objective: To observe the effect of Yi Jin Jing (Sinew-transforming Qigong Exercises) on the muscle strength in senile sarcopenia. Methods: Sixty-five old people with sarcopenia were randomized into Yi Jin Jing group and a blank control group. Thirty-three patients in Yi Jin Jing group practiced Yi Jin Jing (Sinew-transforming Qigong Exercises), while 32 patients in the blank control group didn't receive any interventions. The muscle strength was measured before and after 12-week training. Results: During the study, each group had 1 dropout. The muscle strength was improved after 12-week training in Yi Jin Jing group, and the difference was statistically significant (P<0.05); there was no significant difference in the blank control group (P>0.05). After the intervention, there was a significant difference between Yi Jin Jing group and the blank control group in comparing the muscle strength (P<0.05). Conclusion: Constant Yi Jin Jing (Sinew-transforming Qigong Exercises) training can notably improve skeletal muscle strength in senile sarcopenia.

OBJECTIVETo compare the changes of digestive and absorptive functions in three different models of Pi-deficiency syndrome (PDS).

METHODSExperimental mice were divided into four groups, the control group(CG), the rhubarb group (RG), the exhaustion group (EG) and the over-exertion group(OG). Criteria including general physical signs, D-xylose excretion rate, serum amylase activity, velocity of stomach emptying and enterokinesia, serum gastrin content and indexes of organs were determined before and after treatment.

RESULTSDecrease of D-xylose excretion rate and increase of stomach emptying and enterokinesia velocity appeared in all the three PDS models. As compared with CG, changes of all indices in OG were significant, while the decreasing of spleen index and serum amylase activity in EG, and the changes of serum gastrin content and thymus index in RG were insignificantly different.

CONCLUSIONAll the changes in various criteria showed that PDS mice model established by over-exertion was superior to that established by frequently used methods as purging with rhubarb and exhausting by swimming.

OBJECTIVETo observe the effect of Tangke Decoction (TD) on the expression of TGF-beta1/Smad4 of rats with early diabetes and to explore the effect and mechanism of TD against the renal injury induced by diabetes.

METHODSSD rats were randomly divided into the normal control group (n = 12), the model group (n = 10), the Chinese herbs prevented group (n =10), the Chinese herbs treated group (n = 10), and the Western medicine control group (n = 10). TD (18 mg/kg) was given by gastrogavage to rats in the Chinese herbs prevented group immediately after successful modeling for 12 weeks, once daily. At the 4th week of successful modeling, rats in the rest 4 groups were administered by gastrogavage. Equal volume of normal saline was given to rats in the model group and the normal control group. Benazepril suspension (1 mg/kg) was administered by gastrogavage to rats in the Western medicine control group for 8 weeks, once daily. TD (18 mg/kg) was given by gastrogavage to rats in the Chinese herbs treated group for 8 weeks, once daily. The body weight, kidney weight, index of kidney weight, fasting blood sugar, 24 h urinary albumin excretion rate were examined after experiment. The pathological changes of the renal tissue were observed by HE staining, Masson staining, and electron microscope. The expression of renal transforming growth factor-beta1, (TGF-beta1) and Smad4 were detected using immunohistochemical assay.

RESULTSCompared with the normal control group, the body weight of rats decreased significantly; the kidney weight, index of kidney weight, blood sugar, 24 h urinary protein excretion, the urinary albumin excretion rate,TGF-beta1 and Smad4 expression increased significantly in the model group (all P < 0.01). Compared with the model group, the aforesaid indices were improved in each treatment group with statistical difference (P < 0.05, P < 0.01). Compared with the Western medicine control group, the kidney weight, index of kidney weight, blood sugar, 24 h urinary protein excretion, and the urinary albumin excretion rate were obviously improved in the Chinese herbs prevented group (P < 0.01). The renal pathological changes were most obvious in the model group significantly, but they were improved in all treatment groups.

CONCLUSIONTD could obviously improve the symptoms of diabetes and down-regulate the expression of renal TGF-beta1 and Smad4 of early diabetic nephropathy rats, which suggested that TD had certain preventive effect on early diabetic nephropathy.

AIMIn order to elucidate the underlying mechanism of depressed maximal isometric twitch tension normalized by cross sectional area of muscle strip in unloaded soleus.

METHODSThe soleus and extensor digitorum longus (EDL) muscle strips were perfused in vitro and treated by 2,3-Butanedione monoxime (BDM).

RESULTSThe BDM decreased Pt of soleus and EDL in a concentration-dependent manner. The Pt could restored completely to normal level after washing out BDM. The isometric twitch duration was not altered during 1 mmol/L BDM of perfusion, but was shortened at 10 mmol/L dose. The time from maximal to half Pt in EDL was shorter than that in soleus during 10 mmol/L BDM of perfusion. The inhibitory effects of BDM on myosin ATPase activity were higher in EDL than in soleus. The inhibitory extent of BDM on myosin ATPase activity of soleus and EDL was lower than that on Pt.

CONCLUSIONThese results suggest that reduction in cross-bridge function of skeletal muscle may be one of reasons induced a decrease in its Pt. BDM is not a specific inhibitor on myosin ATPase activity and can affect multiple parts of excitation-contraction coupling in skeletal muscle.

This study is to establish physiologically based pharmacokinetic (PBPK) models of famitinib in rat and monkey, and then to predict the pharmacokinetics and tissue distribution of famitinib in human based on the PBPK models. According to published paper, previous studies and the chemical properties of famitinib predicted by ACD/ADME suite and SimCYP, the PBPK models of rat and monkey were established and optimized using GastroPlus. And then, the PBPK models were applied to predict the pharmacokinetic and tissue distribution of famitinib in human. The results showed that the PBPK models of rat and monkey can fit the observed data well, and the AUC0-∞, ratios of observed and calculated data in rat and monkey were 1.00 and 0.97, respectively. The AUC0-∞, ratios of observed and predicted data in human were 1.63 (rat to human) and 1.57 (monkey to human), respectively. The rat and monkey PBPK models of famitinib were well established, and the PBPK models were applied in predicting pharmacokinetic of famitinib in human successfully. Hence, the PBPK model of famitinib in human could be applied in future drug-drug interaction study.
