Transcranial Doppler can be used for diagnosing,monitoring,identifying the site of arterial occlusion,selecting appropriate cases for thrombolysis,and monitoring arterial recanalization during intravenous thrombolysis,and intra-arterial and intravenous thrombolysis with recombinant tissue plasminogen activator,The continuous monitoring of low frequency transcranial ultrasound has the effect of assisted thrombolysis;however,there are still controversies on the frequencies used in clinical practice.Transcranial Doppler assisted with microbubble contrast agent may further enhance the effect of thrombolysis.

Objective To investigate the diagnostic accuracy of 13C urea breath test (13C-UBT)in the diagnosis of Helicobacter pylori (Hp) infection in patients with gastric remnant.Methods A total of 94 gastric remnant patients (gastric remnant group) and 100 non-gastric remnant patients (control group) received 13C-UBT.According to the course of the disease,the gastric remnant group were divided into group 1 (29 cases,≤5 years),group 2 (33 cases,6 to 10 years) and group 3 (32cases,＞10 years).Before surgery,the diagnosis of Hp infection was according to 13C-UBT and gastric mucosa tissue staining.After surgery,the diagnosis was according to gastric mucosa tissue staining.The applying value of 13C-UBT in gastric remnant patients was evaluated.The consistency of results between 13C-UBT and gastric mucosa tissue staining were evaluated by the Kappa test.Results In gastric remnant group,the Hp infection rate after surgery (37.2％) was obviously lower than that before operation (79.8％;x2 =35.058,P＜0.01) and that of control group (77.0％).After surgery,the Hp infection rate of patients with Billroth Ⅱ gastrectomy (24.4％) was lower than that of patients with Billroth Ⅰ gastrectomy (47.2％ ; x2 =5.133,P=0.023).Before surgery,the Hp infection rate of gastric remnant subgroups were similar (P＞0.05).With the extension of the postoperative course,the Hp infection rate gradually decreased in gastric remnant subgroups (group 1:58.6％,group 2:36.4％,group 3:18.8％; x2=7.839,P=0.021).Setting the cut-off point at 2.0‰ in the gastric remnant group and 3.5‰ in the control group,the accuracy rate of diagnosis was the highest (92.6％ and 96.0％).There was good consistency between the results of 13C-UBT and gastric mucosa tissue staining (Kappa =0.84,P＜0.01).Conclusion With suitable operation and standard,13C-UBT may be a easy,safe and effective assay applied in the gastric remnant patients.

Rhizome atractylodes macrocephalae is the dry roots of Atractylodes macrocephala Koidz. It is one of commonly used Chinese medicine. In the ″Shennong's Herbal″, it was listed as the top grade. It mainly contains volatile oil, atractylenolides, atractylodes polysaccharides, glycosides and amino acids.And it has the medical functions of good for spleen and intestine, diuretic and dehumidifi?cation, hidroschesis, miscarriage prevention and soon.In order to provide references for further devel?opment and utilization, this paper systematic arranged the Chinese medicine atractylodes chemical composition, pharmacological effects, processing technology and effect of processing technology on chemical composition and pharmacological action.

To simplify the macrocyclic fragment and to modify the zinc binding group of the natural product apicidin, two series of S-hexyl (heptyl) ethanethioate derivatives were designed and synthesized. Twenty-six compounds were synthesized and confirmed with 1H NMR, IR, MS and HR-MS spectrum, which were not reported. Take vorinostat as control, their antiporliferative activities against cancer cell lines, MCF-7 and HL-60, were tested with MTT assay or trypan blue staining method. Generally in both series it was found that, the chiral carbon atom at 7 position is not necessary, compounds II-1, II-3, II-6 and II-13 showed good activity on HL-60 cells in vitro, with the IC50 values less than 10 micromol x L(-1). II-7 and II-8 showed stronger activity against MCF-7 than Vorinostat, with the IC50 of 3.19 and 6.29 micromol x L(-1), respectively.

OBJECTIVETo investigate the rule of lymph-node metastasis in gastric cardia cancer and the rational extent of lymph node dissection.

METHODSClinicopathological data of 77 patients with gastric cardia cancer were reviewed and the relationship between extent of lymph-node dissection and prognosis was analyzed retrospectively.

RESULTS(1) The lymph node metastasis rates were 64.9% for N(1), 14.3% for N(2) and 10.4% for N(3). (2) No lymph node metastasis was detected in T(1) stage tumor and maximum diameter of less than 2.0 cm. The lymph node metastasis rates were 20% for T(2), 68.2% for T(3) and 82.8% for T(4) respectively. (3) Lymph node No.1, 3, 2 were often involved in the metastasis of lymph node group 1, and No.7, 8, 10, 9 in Group 2. In lymph node group 3, lymph node metastasis rates were 6.5% for No.5, 1.3% for No.6, 1.3% for No.16 and 2.6% for No.107-110. (4) The five-year survival rates were 36.5% for D(3), 31.3% for D(2), and 22.7% for D(1) lymphadenectomy respectively. The survival rates of patients undergone D(2) and D(3) lymphadenectomy were significantly higher than that undergone D(1) dissection (P<0.05).

CONCLUSIOND(2) or more than D(2) lymphadenectomy associated with enlargement of esophageal hiatus via laparotomy, lower partial esophagectomy and total gastrectomy is able to achieve surgical resectability and improve the survival rate of gastric cardia cancer patients.

Increasing attention has been focused on the antitumor activity of artemisinin derivatives in recent years, for artemisinin had been reported to have cytotoxic effects against HL-60, P388 and MCF-7 tumor cells. We report here the synthesis and evaluation for antitumor activity of a series of artemisinin-ether derivatives bearing tetrahydropyrrole, morpholine, piperidine, substituted piperidines and azoles with various linkers. Sixteen 10-O-substituted dihydroartemisinin derivatives were designed and synthesized, all of which have never been reported in literatures and whose antiproliferative effects on human breast cancer MCF-7, MCF-7/Adr and HL-60 cells were determined by MTT assay or direct cell counting. Each of these artemisinin derivatives possessed better effects than dihydroartemisinin evidently against HL-60 and MCF-7 cells growth, while less potent than doxorubicin. All target compounds exhibited significantly improved potency compared to DHA and doxorubicin on the doxorubicin-resistant MCF-7/Adr cells, so did they in their sensitive counterparts MCF-7 cells. Among them, compounds GF02, GH04 and ZH04 showed strong activity against these three cell lines growth. Further research is undergoing.
