OBJECTIVETo search for a convenient and effective needling method for treatment of hiccup.

METHODSNinety-four cases were randomly divided into treatment group treated by acupuncture at Tianding (LI 17) and a control group treated by selected routine acupoints, 47 cases in each group. They were respectively treated based on differentiation of symptoms and signs for less than 10 sessions, and their therapeutic effects were compared.

RESULTSThe therapeutic effects on primary excess syndrome of intractable hiccup in the two groups were superior to that secondary deficiency syndrome (both P < 0.05); there was no significant difference between the two groups in the therapeutic effect (P > 0.05).

CONCLUSIONAcupuncture at Tianding (LI 17) is a convenient method for hiccup with a definite therapeutic effect.

Objective To investigate the hepatoprotective effect of silybin-phosphatidylcholine complex(SPC) in sepsis rats.Me-(thods) Fifty Wistar immature rats were randomly divided into 3 groups:normal control(10 cases),septic group(30 cases) and interfe-(rence) group(10 cases).In septic group and interference group,rats were treated by cecal ligation and puncture(CLP).Meanwhile,the interference group was given SPC before 2 hours of CLP and after 2 hours of CLP.Blood of rats was taken from all groups to determine the levels of serum tumor necrosis factor-?(TNF-?),interleukin-1(IL-1),alanine aminotransferase(ALT) and aspartate aminotransferase(AST) at varying intervals.Results The levels of serum TNF-?,IL-1,ALT and AST after CLP were significantly elevated in septic group compared with the normal control group(P

Objective: To select the telomerase positive cancer cell lines of gastrointestinal tract and to provide a convinced methodology for future telomerase study. Methods: Fifteen cancer cell lines (carcinoma of stomach 4, of liver 6, of pancreas 2, of colon 3) were cultured and telomerase activity were detected by TRAP-ELISA. The normal hepatic cells were taken as control. Results: Thirteen cell lines were telomerase positive in the 15 lines(86.7%). Conclusion: Most of gastrointestinal tract cancer lines express telomerase, indicating the detection of telomerase activity has clinical potential.

Ticks are obligate ectoparasites and vectors of arboviruses, vickettsiate, spirochetes and parasitil protozoa of humans and domestic animals. Immunological protection of mammalian hosts against tick infestation has been proposed as the most sustainable alternative tick control method to the current use of acaricides. The success of this method is dependent on the identification of key molecules for use as tick vaccine antigens. Proteolytic enzymes are involved in a wide range of cellular processes, thus they can be considered as good target antigens for a tick vaccine. In the present study, we used rapid amplification of cDNA ends protocol and primers that were designed based on the consensus amino acid motifs flanking present in all papain-like cysteine proteinases, to amplify, sequence and characterize two Rhipicephalus haemaphysaloides haemaphysaloides cathepsin L-like cysteine proteinases, named as cysA and cysB. The full length of cysA is 1168bp, encoding a 332 amino acid residue polypeptide with 36.33kD predicted molecular mass; the full length of cysB is 1153bp, encoding a 335 amino acid residue polypeptide with 37.56kD predicted molecular mass. The consensus amino acid motifs flanking presence in both deduced amino acid sequences. And both genes show high sequence homology to other tick cathepsin L-like cysteine proteinase, so they were identified as members of the cysteine proteinase gene family. Expression analysis by RT-PCR revealed that cysA and cysB were expressed differently in different periods of tick development.

Objective To assese the healing of stoma after magnetic anastomosis for the reconstruction of biliary-enteric continuity under severe inflammation.
Methods Acute bile duct injury was constructed as a bile peritonitis model in mongrel dogs (n=32). Magnetic anastomosis (group A, n=16) and traditional suture anastomosis (group B, n=16) were performed to reconstruct the biliary-enteric continuity in one stage. Half of the dogs in each group were euthanized on the 30th postoperative day, and the other half on the 90th postoperative day to harvest the stoma region. The healing conditions of the stoma after the 2 anastomotic approaches were observed with naked eyes, under light microscope and scanning electron microscope.
Results The stoma leakage rate (50%versus 0%on the 30th postoperative day, 37.5%versus 12.5%on the 90th postoperative day, both P<0.05) and stenosis degree (13.9%±0.3%versus 7.1%±0.3%on the 30th postoperative day, 17.2%±0.4%versus 9.4%±0.4%on the 90th postoperative day, both P<0.01) were significantly higher in group B than in group A. Compared with traditional manual anastomoses, the histological analysis under light and electron microscope showed a more continuous stoma with more regular epithelium proliferation and collagen arrangement, less inflammation in group A.
Conclusions Magnetic anastomosis stent ensures better healing of the stoma even under the circumstance of severe inflammation.
