Objective To observe the distribution of TCM syndromes in patients with functional constipation (FC). Methods One hundred and five cases of patients with FC were analyzed with relevant factors and summarized to syndromes of FC by cluster analysis. Results There was a correlation between distribution of syndromes of FC and patient's age, job occupation, course of disease, incentives and patient's eating habits. The distribution of syndromes analyzed by cluster analysis was consistent with diagnostic criteria. Conclusion The syndromes of FC are divided into heat constipation, qi constipation, deficiency constipation and cold constipation. Among these syndromes, the number of excess constipation patients especially heat constipation is more than the number of others.

Drug transporters are functional membrane proteins located in various tissues, which play vital roles in absorption, distribution and excretion of drugs, especially those located in intestine, liver and kidney. The expression and function of transporters will alter in diseases state, which affects the therapeutic effects of drugs by altering their pharmacokinetics. In this review, we focus on the alterations in related transporters and the effect on the drug therapy in common intestinal diseases, liver diseases, kidney diseases and diabetes mellitus.

Objective: To study the influences of steam distillation (SD) on the isomerization of the essential oils of Angelica sinensis (Oliv.) Diel. Methods: SD、GC、GC-MS. Results: The duration of the extraction of essential oils of Angelica sinensis (Oliv.) Diels. by SD was about 14 h, and the yield of (Z)-ligustilide was about 67.1 percent of total (Z)-ligustilide. During the SD, it produced some new components in the essential oils, for example 4-hydroxy-3-methylacetophenone, 2,4,5-benzaldehyde,2,4,5-trimethyl-et al. Conclusion: The results suggested that the extraction of essential oils of Angelica sinensis (Oliv.) Diels. by SD had some disadvantages.

Objective Toexplore the findings of bile flow artifacts (BFA)on MR cholangiopancreatography(MRCP). MethodsEighty five patients with normal common bile duct (CBD)and 95 patients with dilated CBD who had MRCP examination were studied retrospectively. Findings of BFA on original thin images of MRCP were recorded. Date were tested by Chi-square test and Spearman ceefficient of rank correlation analysis. ResultsThe rate of BFA in CBD with normal group was 38. 8％ ( 33/85 ), in dilated group was 83.2％ (79/95), there was statistically significant difference between them( x2 ＝ 37. 512,P ＝ 0. 000). BFA was not observed when the diameter of CBD was no more than 4 mm. BFA was partly observed when the diameter of CBD was 4 mm ＜ ψ≤ 8 mm, single- string sign was predominant findings (52.6％ ,30/57 ). Three-string sign was predominant findings in CBD with slight-dilated group ( 85.7％,36/42). Multi-string sign was predominant findings in CBD with medium-dilated group (84. 6％, 22/26 ).There was statistically significant difference between each groups ( x2 ＝ 284. 561, P ＝ 0. 000 ).BFA had different manifestations with CBD of different diameter, there was relative between them ( r ＝ 0. 553, P ＝0. 000). ConclusionBFA can occur in CBD with normal diameter. CBD with dilated group has higher rate of BFA than CBD with normal diameter. Manifestations of BFA are relative with the diameter of CBD.

Objective To investigate the imaging characteristics of autoimmune pancreatitis (AIP)and its diagnostic value.Methods Imaging examinations and clinical data of 13 patients with AIP were reviewed retrospectively.Results All patients had enlargement of pancreas either diffusely ( n =11 ) or focally in pancreatic head ( n =2 ).The swollen pancreas was of homogeneous density on CT scan ( n =13 ),hypointense on T1-weighted images and mildly hyperintense on T2-weighted images in 4 patients.It was demonstrated as mild enhancement on artery phase of dynamic imaging and progressive enhancement on portal and delayed phase images.Capsule-like enhanced rim was presented around the pancreas in 9 patients.Stricture or obliteration of the common bile duct located in pancreatic head was found in 10 patients accompanied by intrahepatic bile duct dilation.Pancreatic duct was invisible on axial images in 11 cases.Among the 6 patients underwent MRCP,it was showed diffuse and irregular narrowing of the main pancreatic duct and stricture of common bile duct located in pancreatic head in 4 cases.ERCP showed diffuse and irregular narrowing of the main pancreatic duct in 7 cases.Extra-pancreatic lesion included veins around pancreas involvement in 8 cases;multiple low density renal lesions in 6 cases; retroperitoneal fibrosis in 2 cases; stricture of hilar duct,interstitial lung disease and ankylosing spondylitis in 1 case,respectively.Conclusions AIP shows some characteristic imaging features,and imaging examinations play an important role in the diagnosis of AIP.Recognition of extra-pancreatic lesions aids in the correct diagnosis of AIP.

Objective To systematically evaluate the influence of acupuncture-moxibustion on the peroneal nerve conduction velocity in type 2 diabetic peripheral neuropathy (DPN), and to provide clinical references for acupuncture-moxibustion treatment for DPN.Method By searching the CBM, CNKI, VIP, Wanfang, Pubmed, Springer and Medline databases, randomized controlled trials (RCT) of acupuncture-moxibustion for the type 2 DPN published from January 2000 to January 2014 were retrieved and the relevant data of the peroneal nerve conduction velocity were collected for methodological evaluation. RevMan 5.1 software was adopted to conduct the meta-analysis.Result Totally 10 RCTs were recruited with 685 cases involved, including 355 cases in the treatment group and 330 cases in the control group. The meta-analysis results indicated that acupuncture-moxibustion can produce a better effect in improving the motor nerve conduction velocity (MNCV) and sensory nerve conduction velocity (SNCV) of peroneal nerve in type 2 DPN than the treatments used in the control group, and the differences were statistically significant between the two groups [MD=3.55, 95%CI (0.79, 6.31); MD=4.10, 95%CI (0.22, 7.99)].Conclusion Acupuncture-moxibustion can improve the peroneal nerve conduction velocity in type 2 DPN, and thus is worth application in clinic. Due to the limitation of the included studies, such as small sample size and low quality of the articles and high probability of bias, RCTs of large sample size and high quality are required to confirm the above conclusions.

Objective To determine the significance of thymidine phosphorylase for prognosis of HCC.Methods The clinical data and pathological finding of 65 patients with HCC treated in our hospital were retrospectively analyzed.Immunohistochemical staining was performed to evaluate the expression of TP and MVD count.Statistical analysis was used to analyze the relationship between TP expression and other pathological parameters.Survival curves in 54 patients were plotted using the Kaplan-Meier method.Results The positive expressed rate of HCC tissues was significantly higher than that of normal liver tissues (P<0.01).MVD count in positive-TP group and negative-TP group was respectively 16.14±5.11,10.11±4.55.The difference between two groups had statistical significance (P<0.01).TP expression was positively correlated with tumor size,Edmondson-Steiner grade,tumor capsule status,microsatellite marker and tumor thrombi in portal vein (TTPV).The rate of postoperational recurrence after one,two and three years in TP-positive group was respectively 40%,66.7%,79.2% and it was respectively 27.4%,31.3% and 45.7% in TP-negative group.The postoperative recurrence rate after two years and three years in poitive-TP group was significantly higher than that in negative-TP group (P<0.01).In 54 patients with HCC followed up successfully,the total survival rate in TP-positive group was significantly lower than in TP-negative group (P<0.01).Conclusion TP plays an important role in neovascularization of HCC and TP may be a new prognosis index of HCC.
