To explore the new pattern of Chinese medicine solid preparations (CMSP) in vitro dissolution, a method testing the bio-thermal activity in combination with UPLC was used. Microcalorimetry was used to obtain the characteristic metabolic growth power-time curves and a series of biothermodynamic parameters of the inhibition of Staphylococcus aureus by Yinhuang tablet dissolving solutions at the pH 6.8 (phosphate buffer) dissolution medium at different times. From these results, the cumulative dissolution of Yinhuang tablet based on bio-thermal activity was obtained. The dissolution rates of two components of chlorogenic acid and baicalin were determined by UPLC method. Then f2 similar factor method was used to evaluate the relevance of these two methods. The result showed that f2 values all were more than 50, indicating that there is a good correlation between the two methods of measuring the dissolution rate. It is feasible to determine CMSP in vitro dissolution by using bio-thermal activity, and to provide new evaluation methods for controlling the quality of CMSP.

[Objective] To investigate the changes of CD4~+ CD25~+ regulatory T cells (Tr) in peripheral blood and their relation with their body mass index (BMI) of children with acute attack asthma. [Methods] Peripheral blood was obtained from 70 children with acute attack asthma, 30 remission children, and 50 normal control children. Then 70 children with acute attack asthma, were divided by normal weight group (40 cases) and overweight group (30 cases). The levels of CD4~+CD25~+Tr of the patients were tested by flow cytometry (FCM), and their BMI were calculated. [ Results] The levels of CD4~+ CD25~+ Tr [(6.17± 1.72)%] in acute attack group were lower than that in remission group [(7.56±1.48)%] or that in the control group [(7.13± 1.48)%] (P<0.05), but no difference between that in the remission and that in the control (P>0.05). The CD4~+CD25~+Tr of asthmatic children with normal weight [(6.34±1.71)%] was higher than that of asthmatic children with overweight [(4.74±1.20)%] (P<0.05). There was a remarkably negative correlation between the level of CD4~+ CD25~+ Tr of asthmatic children [(6.17±1.72)%] and the BMI (16.00±2.14) (r_p=-0.814, P<0.05). [Conclusion] The levels of CD4~+ CD25~+Tr are remarkable decrease in attack asthmatic children, and more decrease in overweight patients. There is remarkably negative correlation between the levels of CD4~+CD25~+ Tr in peripheral blood of attack asthmatic children and their BMI.

It was concluded that ethanol , acetone and hexane extracts of 11 TCMs including Salvia miltiorrhiza, Cnidium monnieri, Polygonum tinctorium, Taraxacum mongolicum, Morus alba, Glycyrrhiza uralensis, Curcuma longa, Arnebia euchroma, Lobelia chinen-sis , Chrysanthemum indicum and Buddleja officinalis show strong inhibition on Bacillus subtilis , Bacillus cereus , Staphylococcus aureus .

Objective To investigate the effects of bisoprolol combined with rosuvastatin on endothelial function and inflammation in patients with coronary slow flow (CSF). Methods Ninety CSF patients treated from August 2014 to October 2015 were randomly divided into control group, statin group and combined group, thirty cases in each group. The control group was given conventional therapy (aspirin 100 mg/d and isosorbide mononitrate 60 mg/d), statin group was given rosuvastatin 10 mg/d on the basic of control group, while the combined group was given bisoprolol 5 mg/d on the basic therapy of statin group. The serum concentrations of nitric oxide (NO), endothelin-1(ET-1), high-sensitivity c-reactive protein (hs-CRP) and interleukin-6 (IL-6) were detected before treatment and 8 weeks after treatment. The improvement of patients with angina pectoris was evaluated. Results After eight-week treatment, the NO levels were significantly increased in combined group and statin group, while the ET-1, hs-CRP and IL-6 levels were significantly decreased than those before the treatment (P<0.05). At the same time, comparing with the statin group and control group, the NO level was increased in combined group (P<0.05), while the ET-1, hs-CRP, and IL-6 levels decreased significantly (P<0.05). There were significant differences in the effective rates between the combined group (90.0%) and the statin group (83.3%), which were higher than those in control group (56.7%). Conclusion Bisoprolol combined with rosuvastatin can improve the endothelial function and anti-inflammatory in the treatment of CSF.

Objective To evaluate the safety and efficacy of a newly designed anti-reflux metallic stent (ARMS) for malignant extra-hepatic biliary obstruction. Methods A total of 23 patients with unresectable biliary malignancy in the middle or lower part of common bile duct underwent endoscopic retrograde cholangiopancreatography (ERCP) and ARMs placement. The success rate, early complications, stent patency and patients' survival were recorded. Results The ARMSs were successfully placed in all patients and no procedure-related complication was recorded. The average operation time was similar to that of self-expanding metallic stents (SEMs). In 22 patients completing the follow-up, the total serum bilirubin dropped to normal within one month in 20. ARMs dysfunction occurred in 6, including tumor in-growth in 1, overgrowth in 2, and stent dislodgement in 3. Other patients were free of biliary symptoms until death or at the end of follow-up. The average stent patency of ARMs was 14 months. Patency rates at 3, 6, and 12 months were 95%, 74% and 56%, respectively. The mean patient survival was 7. 9 months ( 1-14 months).Postoperative survival rates at 3,6 and 12 months were 91.0%, 81.3% and 17. 2%, respectively. Conclusion Endoscopic placement of novel ARMs in patients with extra-hepatic biliary tumors is feasible,safe and effective.

Objective To evaluate the effect of intensity-modulated radiation therapy(IMRT) on parotid function in nasopharyngeal carcinoma(NPC). Methods Eighty-three NPC patients received prima-ry IMRT between 2001 and 2003. Xerostomia before radiotherapy, at the end of radiotherapy, at 6-month, 1-,2-,3-,4- and 5-year after radiotherapy were investigated, respectively. The relation between xerostomia and parotid dose distribution was analyzed. Results Of all the patients,4,31,31 and 17 had stage Ⅰ,Ⅱ,Ⅲ and ⅣA disease, respectively. Sixteen patients received chemo-radiotherapy. The median followed-up time was 65 months. The 5-year local control and regional control rate were 96% and 95% ,respectively. The 5-year overall survival rate was 80%. The mild xerostomia rate at the seven time points was 42%, 51%, 71%, 77%, 58%, 38% and 26%. The corresponding moderate xerostomia rate was 52%, 53%, 21%,8%, 3%, 2% and 2%, respectively. No serious xerostomia was observed. The mean dose of the bilateral parotid glands was 34.34 Gy. Xerostomia at 6-month after radiotherapy was positively correlated with the mean dose of the parotid glands, and D50 was the independent factor in predicting the xerostomia. Parotid function was well protected when the mean dose and D50 were no more than 33 Gy and 29 Gy,respectively. Conclusions IMRT can improve the local-regional control of NPC and protect the parotid glands from radiation-induced in-jury.
