Objective To assess the value of endoscopic ultrasonography (EUS) and abdominal CT scan on preoperative T and N staging of advanced gastric cancer.Methods A total of 188 patients with advanced gastric cancer received EUS and CT scan to evaluate the T and N staging and lymphatic metastasis before surgical operation.The postoperative pathologic results acted as gold standard for comparison of the two methods.The results consistent with pathologic results were considered as correct otherwise were incorrect.The accuracy of EUS and CT and the each consistency of two methods with pathology were analyzed.Results For T staging, the accuracy of EUS and CT was 87.2%(164/188), 76.6%(144/188), respectively, and Kappa value of EUS and CT was 0.726 and 0.509, respectively.There was a statistical difference between the two methods(χ2=7.181,P=0.007).For lymph node metastasis, the accuracy of EUS and CT was 72.9%(137/188) and 79.8%(150/188), respectively, and Kappa value of EUS and CT was 0.397 and 0.487, respectively.No statistical difference was found between them(χ2=0.963,P=0.326).The consistency test between the two methods for T and N staging and lymph node metastasis revealed that the Kappa value was 0.507 and 0.649, respectively.The accuracy of EUS on T staging was 93.0%, 93.3%, 96.8% and 91.5% in cardiac cancer, gastric fundus cancer, gastric corpus cancer, and gastric antrum cancer, respectively.Corresponding Kappa value in the 4 different positions were 0.843,0.881,0.940 and 0.710, respectively according to consistency tests.The accuracy of gastric antrum cancer with pylorus invasion was 63.2% and the consistency test Kappa value was 0.340.Conclusion EUS is an accurate method for T staging and lymphatic metastasis of advanced gastric cancer, but there is a lower accuracy for T staging of gastric antrum cancer with pylorus invasion.

A Comprehensive review was present on the sources, enzyme stru cture, enzyme reaction mechanism and the application of the nitrilase.

The aim of this study is to prepare self-microemulsifying drug delivery system (SMEDDS) of the mixture of paeonol (Pae) and borneol (Bor). Solubility test, ternary phase diagrams and simplex lattice method were employed to screen and optimize the formulation of the mixture of Pae and Bor-loaded SMEDDS. After formed into microemulsions, the particle diameter (PD) was determined and a TEM was employed to observe the microemulsions' morphology. The contents of Pae and Bor were determined by gas chromatography. As a result, while ethyl oleate (EO) as the oil phase, cremophor EL35 (EL35) as surfactant and Transcutol HP (HP) as cosurfactant, the range of the microemulsion on the ternary phase diagram was larger than other combinations. And at a ratio of 20:45:35, the microemulsions' PD was about 34 nm and the polydispersity index (PI) was about 0.2. There were 16% of Pae, 2% of Bor, 16% of EO, 37% of EL35 and 29% of HP in the prepared SMEDDS. The preparation process of the Pae and Bor-loaded SMEDDS based on Xingbi Fang is simple and feasible. This study provides a reference for the researches on the related traditional Chinese medicine and the related components.

OBJECTIVE To investigate the curative effect and mechanism of allo-bone marrow mes-enchymal stem cell(BM-MSC)infusion in the experimental autoimmune thyroiditis(EAT)mouse model. METHODS An EAT mouse model was established in C57BL/ 6 mice using porcine thyroglobulin(PTg) and Freund adjuvant,while BM-MSCs were injected into the EAT mice of BM-MSC treated group,3×105 per mouse on the 0,7th,14th and 21st day. On the 28th day,all the mice were sacrificed,and thyroid tissue was isolated,embedded in paraffin and stained with HE staining for histological examination. Serum was collected to assess the level of thyroglobulin antibodies( TgAb ) ,thyroid microsomal autoantibodies( TmAb),antithyroid peroxidase antibodies( TPOAb),3,5,3 ',5 '-tetraiodothyronine (TT4),3,5,3 '-triiodothyronine( TT3),interleukin-10( lL-10) and interferon-γ( lFN-γ ). RESULTS① Thyroid tissue in model group showed inflammatory response and infiltration. The level of TmAb, TgAb and TPOAb was significantly increased compared with normal control group,but the level of TT4 was decreased while there was no change in the level of TT3,suggesting that an EAT mouse model was established. ② The thyroid in model group and BM-MSC treated group showed inflammatory response and inflammatory cell infiltration,but the response in BM-MSC treated group was weaker than in model group. ③ Compared with model group,the level of TgAb,TmAb,TPOAb and lFN-γ was decreased obvi-ously(P﹤0.05),the level of TT4 and lL-10 was increased significantly(P﹤0.05),but the level of TT3 changed little in BM-MSC treated group. CONCLUSION BM-MSCs may partly restore the immunologi-cal homeostasis state. The mechanism may be related to its modulation of immune balance of Th1/ Th2.

Objective To explore the effect of surgical treatment on primary gastrointestinal non-Hodgking lymphoma(NHL) in children.Methods Nine cases of clinical and follow-up data of primary gastrointestinal NHL were studied retrospectively to evaluate the effect of surgical treatment on primary gastrointestinal NHL in children.Results Seven cases were male and 2 cases were female.The mean age was(5.59?3.27)years old.The clinical manifestation included abdominal mass (7 cases),abdominal pain (5 cases),fever (2 cases),haematemesis and melena (2 cases),constipation (1 case) and paroxysmal abdominal pain with vomiting (1 case).Nine cases were diagnosed as primary gastrointestinal NHL,including 1 case of intussusception,1 case of acute appendicitis,2 cases of gastrointestinal obstruction,2 cases of gastrointestinal bleeding and 3 cases of abdominal mass.One case received the operation of intussusception reduction,tumor resection and intestinal anastomosis.One case received appendectomy.One case received the operation of tumor biopsy and transverse colon colostomy.Six cases received laparotomy.Six cases were diagnosed as Burkitt lymphoma.One case was anaplastic large cell lymphoma and 2 cases were diffuse large B-cell lymphoma.One case was at stage Ⅰ,1 case was at stage ⅠE,2 cases were at stage Ⅱ,3 cases were at stage ⅡE and 2 cases were at stage Ⅲ.Nine patients had received operation.One case died after operation and 8 cases had received combined chemotherapy.The 1 and 3 years survival rates were 75.0% and 37.5%,respectively.Conclusions Acute abdomen is often the first symptom of primary gastrointestinal NHL in children and comprehensive surgical treatment is an effective procedure for it.

Objective To study the nasal mucosa absorption of paeonol ofXingbi microemulsion-based thermo-sensitive gel in rats; To evaluate the nasal mucosa absorption of medicine and the rationality of preparation form.Methods According to the nasal administration method, the blood medicine concentration of paeonol was determined at different time points.Results The nasal administration bioavailability of paeonol in Xingbi microemulsion-based thermo-sensitive gel was 78.68%, the plasma concentration reached the maximum (0.3404 μg/mL) after 3 min of administration, and the average residence time was 9.23 h. After reaching Cmax, The plasma concentration changed similar to intravenous administration of paeonol. The concentration data of paeonol in plasma was consistent with a two-compartment model, with a weight of 1.Conclusion Xingbi microemulsion-based thermo- sensitive gel has a higher bioavailability, and the preparation form was reasonable.

OBJECTIVETo systematically assess the efficacy and safety of Rhodiola in treating chronic stable angina pectoris.

METHODSOur group searched the Cochrane library, PubMed, Embase, Chinese biomedical literature database (CBM), VIP database (VIP), Chinese Journal Full-text Database (CNKI) for the literature published in English and Chinese till April 2013. Randomized controlled trials (RCTs) were included on the therapeutic effect of Rhodiola or Rhodiola plus conventional Western medicine in comparison with the conventional Western medicine treatment on stable angina. Data were extracted according the data extraction form. The literature methodological quality was assessed by using the Cochrane handbook, and data analyzed by Rev-Man 5.2 Software for Meta-analysis. The effect indicators of outcomes was expressed by odds ratio (OR) and 95% CI.

RESULTSA total of 7 randomized controlled trials, 662 cases of stable angina pectoris patients met the inclusion criteria and all published in Chinese, without one scientific design and high quality literature. Compared with the conventional Western medicine treatment, combined with oral administration of Rhodiola could improve the efficiency of anti-angina (OR = 2.49, 95% CI: 1.02 - 6.09). Combined with intravenous infusion of Rhodiola could also improve the efficacy of angina pectoris (OR = 4.86, 95% CI: 2.4 - 9.82). Oral administration of Rhodiola couldn't improve ECG efficacy (OR = 1.25, 95% CI: 0.67 - 2.34). Intravenous infusion of Rhodiola could improve the clinical efficacy (OR = 2.94, 95% CI: 1.61 - 5.35). Combined with the conventional treatment, intravenous infusion of Rhodiola could improve the whole blood viscosity (low and high shear rates) and inverse variance (IV) (-1.36 and -0.99, 95% CI: -1.65 - 1.07 and -1.26 - 0.71), but could not reduce serum fibrinogen and D-dimer level. The incidence rate of adverse reactions was higher than that of the conventional treatment combined with Rhodiola (OR = 0.1, 95% CI: 0.02 - 0.51).

CONCLUSIONSOn the basis of routine treatment, Rhodiola could further improve patients' symptoms. Combined with intravenous medication, Rhodiola could increase the ECG improvement rate, and reduce adverse reactions. But the methodological quality of included studies was poor, the number of samples was small, and influence factors such as the intervention period was short. This conclusion needs scientific and rational design in a larger sample, multicenter clinical trial to verify.

Objective:It has been proposed that blood pressure variability(BPV) is positively related to end-organ damage(EOD) in hypertension.The present work was designed to observe the effects of long-term treatment with nitrendipine and hydralazine on BPV and EOD in spontaneously hypertensive rats(SHR),to examine the hypothesis that lowering BPV with an antihypertensive drug is an important factor in organ protection.Design and methods:Drugs were mixed in rat chow.After 4 months of drug administration,blood pressure was recorded continuously in conscious freely moving rats for 24 h.The heart,kidneys,and brain were then isolated and examined.Results:It was found that nitrendipine significantly decreased blood pressure and BPV,and significantly decreased EOD score in SHR.Hydralazine decreased blood pressure,but did not lower BPV.No effect on EOD was found in hydralazine-treated rats.In control rat(n=38),EOD score was weakly related to systolic blood pressure(r=0.331,P<0.05) and closely related to long-term systolic BPV(r=0.551,P<0.01).In nitrendipine-treated rats,EOD score was closely related to long-term systolic BPV(r=0.602,P<0.01),but not to blood pressure level(r=0.174,P>0.05).Conclusion:BPV plays an important role in the organ-protecting effects of nitrendipine.
