By using the method of philology, 65 Hui prescriptions for treating cough were been collected to compare Arabic and Chinese names of pennisetum, anemarrhenae, honey, pease, white mustard, perilla and towel gourd stem. The Countif function in Microsoft Excel 2007 was used to count frequency of drugs in the prescriptions and summarize eight common Hui medicine for treating cough, namely sugar, honey, almond, fritillaria, liquorice, orange peel, white mulberry root-bark and lily. According to the commonly used drugs, philological studies and theories of Hui medicines, pathology and therapy of Hui medicines for treating cough were preliminarily inferred. In this study, 35 practical prescriptions and 30 simple and convenient Halal dietary prescriptions were summarized from collected prescriptions according to relevant literatures. On the basis of the long-lasting unique dietary therapy culture developed for Hui people, the simple and practical dietary prescriptions were defined according indications, therapy, prescription name and composition, and eight types of drug-admixed foods were summarized to relieve pains and improve health awareness and quality of life. Meanwhile, this study could also enrich and perfect the prescriptions, provide new ideas for improving health of patients, and lay a certain realistic foundation for further study of Hui medicines.

Studying the essence of syndromes (Zheng) in traditional Chinese medicine (TCM) is a fundamental challenge in basic theoretical research of TCM. The relationship between any given syndrome and biochemical indicators is one of the important aspects of the study. As the indexes selected in each study are specific to a particular Western medical disease diagnosis, and the disease factor is inevitably introduced into the study, the effect of disease factor on the index changes cannot be assessed effectively by traditional data processing methods. This is known as "the same syndrome with different reasons", which has resulted in confusion in TCM research. This study aimed at providing a mathematical tool to address this issue. Based on information theory and the residual-split method, the syndrome information, which was covered in the index variation, was quantitatively calculated in this paper as an independent part of the disease factor. A mathematical model capable of objectively assessing and statistically testing the effect of the syndrome factor on the index changes was established. Applying this model to literature data of studies on the relationship between cyclic nucleotides and yang-deficiency syndrome showed following results. First, the values of yang-deficiency syndrome information were negative for cyclic adenosine monophosphate (cAMP) while positive for cyclic guanosine monophosphate (cGMP) in all included literature. This indicated that the group of yang-deficiency syndrome was correlated with an obvious trend of reduced cAMP levels and increased cGMP levels. Second, the statistical test results of yang-deficiency syndrome information of the two indexes were different among the literature included. The quality of original data was considered as a possible reason. Third, the significant differences between the yang-deficiency group of a specific disease and the normal group may, in some cases, be caused by a disease factor rather than a syndrome factor. The mathematical model provided a reasonable mathematical tool for the analysis of disease factor and syndrome factor in clinical research of TCM, suggesting that the mathematical model may give rise to innovative ideas and methods in the study of syndromes.

Intestinal schistosomiasis is a kind of intravascular parasitic diseases, and chronic inflammation of colon is one of the basic pathological changes of the sickness.However, the mechanism of caveolin-1 and tight junction proteins in the pathogenesis of intestinal schistosomiasis is still unclear.Aims: To study the expressions and significances of caveolin-1 and tight junction protein occludin, claudin-1 in schistosomiasis colitis in mice.Methods: Forty BALB/c male mice were randomly divided into control group and infection group.Schistosomiasis colitis model was established by placing 40 Schistosoma Japonicum cercarie on the abdomen.Mice were sacrificed after 8 weeks.HE staining was performed.The permeability of intestinal vascular endothelium was detected by Evans blue method.The leukocyte counts in peritoneal lavage fluid were measured.qPCR was used to determine the mRNA expressions of caveolin-1, occludin, claudin-1 and eNOS in colon tissue.Western blotting and immunohistochemistry were used to detect the protein expressions of caveolin-1 and occludin.Results: Large number of egg granuloma was observed in colon submucosa and accompanied by extensive inflammatory cells infiltration in infection group.Compared with control group, content of Evans blue and leukocyte counts in peritoneal lavage fluid were significantly increased (P<0.05);mRNA expressions of caveolin-1, occludin, claudin-1 were significantly decreased (P<0.01);protein expressions and positivity rates of caveolin-1 and occludin were significantly decreased in infection group (P<0.05).Conclusions: Down-regulation of expressions of caveolin-1, occludin and claudin-1 can induce leukocyte accumulation via increasing the permeability of intestinal vascular endothelial cells, thereby involving in the development of schistosomiasis colitis.

Knowledge Discovery in Databases is gaining attention and raising new hopes for traditional Chinese medicine (TCM) researchers. It is a useful tool in understanding and deciphering TCM theories. Aiming for a better understanding of Chinese herbal property theory (CHPT), this paper performed an improved association rule learning to analyze semistructured text in the book entitled Shennong's Classic of Materia Medica. The text was firstly annotated and transformed to well-structured multidimensional data. Subsequently, an Apriori algorithm was employed for producing association rules after the sensitivity analysis of parameters. From the confirmed 120 resulting rules that described the intrinsic relationships between herbal property (qi, flavor and their combinations) and herbal efficacy, two novel fundamental principles underlying CHPT were acquired and further elucidated: (1) the many-to-one mapping of herbal efficacy to herbal property; (2) the nonrandom overlap between the related efficacy of qi and flavor. This work provided an innovative knowledge about CHPT, which would be helpful for its modern research.

Objective To investigate the dosimetric properties of PTW 60019 synthetic diamond detector in small photon beams.Methods A PTW 60019 synthetic diamond detector was tested under 6 and 10 MV photon beams,respectively.Linearity with dose,dose rate dependence and off-axis ratio were measured and compared to those measured by an IBA SFD.Percentage depth doses were measured and compared to those measured by an IBA SFD and a PTW 31010 semiflex chamber.Total scatter factors were measured and compared to those measured by an IBA SFD and a PTW 31016 PinPoint chamber.Results The dose response of a PTW 60019 synthetic diamond detector showed a good linear behavior as a function of dose,with observed deviations below 0.2％ over a dose range from 100 to 1 000 MU.The dose rate response was almost independent,with deviations below 0.2％ in the dose rate range from 37 to 614 MU/min.For the fields of 20-100 mm in diameter,there were dose differences in percentage depth doses within 1％ as compared to an IBA SFD and a PTW 31010 semiflex chamber.For the 10 mm diameter field,the differences were up to 5.8％ in the build-up region.Off-axis ratios measurements showed a good agreement among the involved detectors (＜ 1％).The higher differences appeared in the penumbra region.A good agreement was also found in terms of total scatter factor measurements for the related detectors.Conclusions The observed dosimetric properties of the PTW 60019 synthetic diamond detector indicate that it is a suitable candidate for small photon beam dosimetry.

Objective To investigate the effects of different doses of propofor on ATP-sensitive K~+currents(I_KATP)in human atrial myocytes and the underlying mechsnism.Methods A small piece of myocardiumwas obtained from right atrium in patients undergoing atrial septal defect or ventricular septal defect surgery.Themyocardium specimen was placed in cold Ca~(2+)-free cardioplegic solution aerated with 100% oxygen.Themyocardium specimen was cut into small chunks(1 mm~3).Atrial myocytes were isolated by enzymatic dissociationtechnique.The effects of propofol on I_KATP in atrial myocytes were studied using the whole-cell configuration ofpatch-clamp technique.Results The outward currents were recorded with a pipitte solution containing 0.3mmol?L~(-1) ATP.The currents were inhibited by glibendamide 10 ?mol?L~(-1),a specific K_ATP channel inhibitor,suggesting that the outward currents were I_KATP.I_KATP aws activited by propofol in a dose-dependent manner.Conclusion Propefol can activate the I_KATP in human myocytes in a concentration-dependent manner and themechanism of its myocardial depressant action may be partly explained.

Objective To investigate the feasibility and clinical efficacy of the interventional thrombolytic therapy in acute segmental renal infarction.Methods From December 2007 to November 2015 data of patients with acute segmental renal infarction treated in our institute were retrospectively reviewed. There were 5 male patients and 2 female patients, All patients age ranged from 45 to 76 years old ( median 70 years old), All patients had clinical symptoms,including left flank pain with vomiting in 3 patients and right flank pain with vomiting in 4 cases. 4 cases with cerebral thrombosis, atrial fibrillation and hypertension, 3 cases had hypertension and diabetes.4 cases was possible of renal artery embolism diagnosed by Doppler ultrasound, renal arteries showed no abnormality, while other 3 cases had no obvious symptoms.CT test revealed low density area wedge-shaped, coated substrate edge, but no obvious occupying lesions in the pole of the kidneys.Furthermore, enhanced scan showed uneven enhancement, delayed distortion, and the lesion density below the renal parenchyma in the pole of the kidneys.Digital subtraction angiography ( DSA) were performed and the patients were given saline 20 ml and urokinase200 000 U at 15 minutes interval through indwelling catheter injection two times, followed by normal saline 20 ml and urokinase100 000 U injection once.Subsequently, the patients were given urokinase 100 000 U through the indwelling catheters infusion every four hours.Concurrently, the patients were given 6 000 U of low molecular weight heparin sodium injection subcutaneously every 12 h, as well as expansion treatment. 24 hours after the treatment, observing the infarction area by the original DSA catheter angiography.Results All patients were successfully treated.Followed up for 3 months to 7 years, 1 patient died of cerebral infarction and hypertension after 8 months, other patients were alive without evidence of renal infarction recurrence in CT examination, and condition of patients with atrial fibrillation gradually recovered. Conclusion The diagnosis of ASRI requires enhanced CT and DSA examination due to its rare incidence and the high misdiagnosis rate in clinic.Early diagnosis and use of interventional thrombolytic therapy method is a feasible and effective treatment method.

Objective To evaluate the reliability of a rat model of acute cerebral ischemia and reperfusion by using cerebral perfusion functional CT.Methods A stable and reversible focal ischemia model with unilateral middle cerebral artery occlusion was established and evaluated by CT perfusion imaging and TTC staining.Results Artificial Occlusion of the MCA resulted in ipsilateral cerebral infarcts in all study animals.Hypoperfusion was definitely recorded in all CT perfusion images obtained after MCA occlusion and was significantly correlated with the final lesion size.Blood flow was restored after pulling the thread out of the artery.Conclusions The method of establishing an acute focal cerebral ischemia and reperfusion model by thread insertion in our study is simple and stable.If we can screen the stroke model with CT perfusion examination,the error caused by variance of model can be reduced.Thereby it provides a platform for researchers to investigate acute cerebral ischemia and recirculation.

Objective To investigate the feasibility of using CT texture analysis to differentiate among lipid-poor adrenal adenoma,pheochromocytoma and adrenal metastases.Methods 66 lipid-poor adrenal adenoma,98 pheochromocytoma and 101 adrenal metastases lesions were analyzed retrospectively.All the patients had abdominal non-enhanced CT and adrenal enhanced CT scans.We used TexRAD software to analyze the textural features of CT images and compared the differences in each texture parameter among three adrenal lesions.Results On non-enhanced CT images,there were significant differences in Mean and Kurtosis at all the texture scales(SSF 0-6) among the three types of adrenal lesions (P<0.05),as well as SD at fine and coarse texture scale (SSF 2,6)(P<0.05).Entropy (SSF 0-3, 5-6) and MPP (SSF 0-2, 4-6) were significantly lower in lipid-poor adrenal adenoma and adrenal metastases than that in pheochromocytoma (P<0.05).There were significant differences in Skewness (SSF 0-3) among three types of lesions, which was lowest in pheochromocytoma and highest in adrenal metastases.On enhanced CT images, Mean, SD, Entrophy and MPP showed significantly differences among the three types of adrenal lesions at all the texture scales (SSF 0-6) (P<0.05), which were all highest in pheochromocytoma and lowest in adrenal metastases.Skewness (SSF 0) and Kurtosis (SSF 0, 2) were significantly lower in adrenal metastases than that in lipid-poor adrenal adenoma and pheochromocytoma (P<0.05).Conclusion There are significant differences in CT texture analysis parameters among lipid-poor adrenal adenoma,pheochromocytoma and adrenal metastases.CT texture analysis has potential clinical application values in differentiating these three adrenal lesions.
