Inner fistula by abdomino-back anastomosis of cephalic vein to radial artery was erformed in 86 patients with hemodialysis (test group) and end-to side arteriovenous anastomosis was performed in 85 cases (control group).There were no significant differences in postoperative anastomotic blood flow and vascular complications between two groups (P ＞ 0.05);however the average time consuming for operation in test group was shorter than that in control group (36 min vs.75 min,P ＜ 0.01).The minimally invasive abdomino-back anastomosis is a desired arteriovenous fistula method for hemodialysis patients.

Astragalus polysaccharides was lounded to 4-(2-aminoethylphenol), followed by labeling the APS-Tyr with fluorescein-5-isothiocyanate (FITC) at the secondary amino group. The absorption enhancement effects of low molecular weight chitosan and protamine on astragalus polysaccharides were evaluated via Caco-2 cell culture model. The results show that the fluorecent labeling compound has good stability and high sensitivity. On the other hand low molecular weight chitosan and protamine also can promoted absorption of the astragalus polysaccharides without any cytotoxity, and the absorption increase was more significant with increasing the amount of low molecular weight chitosan and protamine. At the same time, the low molecular weight chitosan has slightly better effect. The transepithelial electric resistance (TEER) of Caco-2 cells show that absorption enhancers could improve its membrane transport permeability by opening tight junctions between cells and increasing the cell membrane fluidity.

OBJECTIVETo summarize the complications and the early clinical effect of less invasive stabilization system and the femoral condylar support plates in the treatment of AO type C distal femoral fractures.

METHODSFrom September 2007 to February 2012, 46 patients with AO type C distal femoral fractures were retrospectively studied. Of all patients 25 were treated with less invasive stabilization system including 14 males and 11 females with a mean age of (56.3±4.2) years old; according to AO classification, there were 14 cases of C1, 8 cases of C2 and 3 cases of C3 with a mean hospital stay of (15.6±1.7) days. While 21 cases were treated with femoral condylar support plates fixation including 12 males and 9 females with a mean age of (53.8±5.1) years old;there were 13 cases of C1, 6 cases of C2 and 2 cases of C3 with a mean hospital stay of (17.8±2.2) days. Comparative analysis was performed from the operation related index,postoperative complications and Evanich score of the knee joint function between the two groups at follow-up.

RESULTSAll 46 patients were followed up from 13 to 38 months with a mean time of 19.6 months after surgery. Complications included 1 case with infection,3 cases with internal fixation failure, 1 case with nonunion and 1 case with activity limitation of the affected knee. The differences in the incision length, blood loss, fracture healing time were significant between two groups (P<0.05), while there was no significant difference in the duration of operations, hospital stays and the incidence of postoperative complications between two groups (P>0.05). The statistical significance was also found in the Evanich score at last follow-up between two groups (P<0.05).

CONCLUSIONPatients with less invasive stabilization system fixation had the characteristics of less trauma, shorter fracture healing time and better functional recovery. Less invasive stabilization system had became one of the ideal internal fixations in the treatment of AO type C distal femoral fractures.

Objective To investigate whether pantoprazole (PPZ), a proton pump inhibitor,could reverse the transmember pH gradient by inhibiting vacuolar H+-ATPase so as to increase the sensitivity of human gastric adenocarcinoma cell line SGC7901 to antitumor drugs and to evaluate the optimal time of drug administration, dosage of PPZ and the possible mechanism. Methods Western blotting and immunofluorescent staining were used to determine the expression and intracellular distribution of vacuolar H+-ATPase in human gastric adenocarcinoma cell line SGC7901 with or without PPZ pretreatment. 2', 7'-bis-(2-carboxyethyl)-5-(and-6)-carboxyfluorescein, acetoxymethyl ester (BCECF-AM) fluorescent probe was used to measure the intracellular pH value of human gastric adenocarcinoma cell line SGC7901 which pretreated with different dose and time of PPI. Methyl thiazolyl tetrazolium (MTT) assay and annexin V-fluorescent isothiocyanate-propidium iodide double staining were performed to evaluate the cytotoxic effects and apoptosis of cells treated with antitumor drugs combined with PPZ. Adriamycin (ADR) was used as probe to estimate drug accumulation and retention with PPZ pretreatment. Results After 24 hours, the expression of vacuolar H+-ATPase in cells pretreated with PPZ of 10 μg/ml (1.19±0.03) or 100 μg/ml (0. 70±0.03) was significantly lower than that in blank control (1.53±0. 05), but this expression was increased by pretreatment with PPZ of 1 μg/ml (2.29 +0.06, P<0.05). The inhibitory effects of PPZ (10 μg/ml) on vacuolar H+-ATPase was observed at 6 hours (0.32±0.02)and 12 hours (0. 13±0.02). And it could alter the intracellular distribution of vacuolar H+-ATPase at 24-hours. The intracellular pH value in cells pretreated with PPZ of 10 μg/ml (7.44±0. 09 ) or 100 μg/ml (7.31 ± 0. 06) was significantly decreased in comparison with untreated cells (7.51±0.05, P< 0. 01). After administration of anti-tumor drugs, the viability in SGC7901 cells pretreated with PPZ for 24 hours (58.71%±1.18 %) was significantly lower than that in cells untreated with PPZ (74. 33% ± 1.77%, P<0.05), while thetotal and early apoptotic rates in former cells(80.81% ±1. 16% and 77.52 %±1.13 %, respectively) were significantly higher than those in later cells (26. 42%±1.19% and 23. 18% ±0.92%,respectively,P < 0. 01). And the ADR releasing index in cells treated with PPZ (20, 50 and 100 μg/ml) for 24 hours was obviously lower than that in the blank control (0. 164±0. 013, 0. 162±0.015, 0. 152±0. 012 vs 0. 277±0. 011, respectively, P<0. 01). Conclusion The sensitivity of human gastric adenocarcinoma cell line to antitumor drugs may be increased by pretreatment with PPZ.

Many Chinese drugs (CHD) have showed their significant effects of integral immune-regulation, and lots of researches have conducted in recent years for exploring their mechanism from different levels, like cytological, molecular and genetic levels. In this paper, the relation between immune-regulation of CHD and Toll-like receptors/nuclear factor-kappaB (TLRs/NF-kappaB) signaling pathway was introduced in brief based upon the achievements of previous researches. It was pointed out that the two are closely related, to explore mechanism of CHD in this way is meaningful not only for further deepening the theoretical understanding of CHD's pharmacological immunoregulation, but also be practically facilitate for enhancing therapeutic efficacy of CHD and developing new CHD.
