OBJECTIVETo study the protective effect of dl-tetrahydropalmatine(dl-THP) on liver injury induced by carbon tetrachloride (CC4) in mice.

METHODMice were administracted with dl-tetrahydropalmatine ip 20, 40 mg x kg(-1) daily for 9 d respectively, and then actue liver injury model was induced by 0.1% carbon tetrachloride ip 20 mL x kg(-1). The mice were killed 17 h after injection ip of CCl4, serum alanine and aspartate aminotransferase (ALT and AST) activity were measured, and maleic dialdehyde (MDA) and superoxide dismutase(SOD) activity in liver were detected.

RESULTdl-THP significantly reduced the level of serum ALT and AST, inhibited lipoperxidation in liver, while increased SOD activity in liver tissue. Degeneration of hepatocytes was obviously prevented in mice treated with dl-THP, and the liver histological structure was well maintained.

CONCLUSIONdl-THP has inhibitory effects on liver injury induced by CCl4 in mice. The mechanisms may be related with its effects of reducing lipid peroxidation product.

OBJECTIVETo construct tissue-engineered neural complex in vitro and study its effect in repairing acutely injured spinal cord in adult rats.

METHODSNeural stem cells were harvested from the spinal cord of embryo rats and propagated in vitro. Then the neural stem cells were seeded into polyglycolic acid scaffolds and co-cultured with extract of embryonic spinal cord in vitro. Immunofluorescence histochemistry and scanning electron microscope were used to observe the microstructure of this complex. Animal model of spine semi-transection was made and tissue-engineered neural complex was implanted by surgical intervention. Six weeks after transplantation, functional evaluation and histochemistry were applied to evaluate the functional recovery and anatomic reconstruction.

RESULTSThe tissue-engineered neural complex had a distinct structure, which contained neonatal neurons, oligodendrocytes and astrocytes. After tissue-engineered neural complex was implanted into the injured spinal cord, the cell components such as neurons, astrocytes and oligodendrocytes, could survive and keep on developing. The adult rats suffering from spinal cord injury got an obvious neurological recovery in motor skills.

CONCLUSIONSThe tissue-engineered neural complex appears to have therapeutic effects on the functional recovery and anatomic reconstruction of the adult rats with spinal cord injury.

OBJECTIVETo evaluate the efficacy and safety of live combined Bifidobacterium, Lactobacillus and Enterococcus capsules in treatment of irritable bowel syndrome.

METHODSEighty-five patients [male 32, female 53; age (45.31+/-11.72) years] were given live combined Bifidobacterium, Lactobacillus and Enterococcus capsules 1260 mg/d t.i.d.x4 weeks. Syndrome scales were used to evaluate the efficacy in gastrointestinal syndrome. Fecal flora was also measured before and after the treatment. Six bacteria were cultured and the colony forming units were counted in stool. SPSS was used for data analysis.

RESULTSSeventy-four patients finished the follow-up. No side-effect was found. For treatment of irritable bowel syndrome, the effective rate of live combined Bifidobacterium, Lactobacillus and Enterococcus capsules was 56.8% in the second week, 74.3% in the fourth week and 73.0% in the sixth week. Single symptom was improved, especially in abdominal pain and stool character. The probiotica containing live combined Bifidobacterium, Lactobacillus and Enterococcus could increase bifidobacterium count (P<0.01) and lactobacillus count (P<0.05); decrease bacteroides count (P<0.05) and enterococci count (P<0.01); No obvious changes were observed in clostridium difficile colonitis and enterobacteriaceae (P>0.05).

CONCLUSIONThe result of the study indicated that the administration of live combined Bifidobacterium, Lactobacillus and Enterococcus improved the symptom of irritable bowel syndrome and that there was a gradual increase of this effect. Thereafter conditions remained stable for 2 weeks. That improvement may be associated with alterations in gastrointestinal flora.

OBJECTIVETo compare the influences of stapedectomy and small fenestra stapedotomy on the hearing of guinea pigs.

METHODSTwenty-four (48 ears) guinea pigs were randomized equally into two groups, and the left ears were subjected to stapedectomy and total stapes replacement with a prosthesis, or sham operation (12 ears) to expose the footplate of the stapes and the round window. Each guinea pig was tested by ABR perioperatively. Four guinea pigs were chosen randomly from each group and decapitated for morphological examination by light microscopy and scanning electron microscopy after ABR test.

RESULTSIn the sham operation group, the post-operative latencies of each wave, the intervals and the hearing threshold exhibited no significant changes other than prolonged latency of wave I. In stapedectomy group, the hearing threshold increased to 23.75-/+3.77 dBSPL 1 h after operation with significantly prolonged post-operative latencies of all the waves and intervals but for III-IV interval, which was shortened. The latencies of each wave (especially waves I and III) in the stapedectomy group were increased by a greater magnitude than those in the sham operation group, but the intervals were comparable between the two groups. No significant difference was noted in the parameters of ABR either 1 h or 1 day after the operation between the two groups, in which the architecture of cochleas remained intact with similar number of spiral ganglion cells. The stereocilia of the outer hearing cells (OHC) were normal in the sham operation group while in stapedectomy group, slight stereocilia disorder occurred but became normal 1 day after operation. No obvious changes were found in the stereocilia of the inner hearing cell (IHC) in either groups.

CONCLUSIONStapedectomy can induce mild hearing loss without seriously damaging the function of the cochlea in guinea pigs.
