OBJECTIVETo observe the effects of H. dulcis on relieving alcohol toxicity by animal experiments.

METHODMale kunming mice were ovraiectomized and randomly divided into 5 groups: control group, model group, and aqueous extracts of H. dulcis group at 0.5, 0.25, 0.125 g x mL(-1). The acute alcohlism animals induced by gastral administration with "Er Guo Tou" and the alchol concentrations in serum were detected after treated with the extracts within 0.5-3 h by biochemical enzymes.

RESULTThe alcohol concentration in blood was up to the maximum in 0.5-1.5 h. However, the alcohol concentrations in blood of aqueous extract from H. dulcis group were decreased in 0.5-3 h. The activity of ADH in the liver in aqueous extract of H. dulcis group was increased in 2-3 h, while it was significantly increased in 1-1.5 h (P <0.05).

CONCLUSIONThe aqueous extract of H. dulcis could reduce the alchol concentration in blood of animals and inrease the activity of ADH after given alcohol. It means the extract has the effect of relieving alcohol toxicity and preventing drunkenness through restraining the absorption of alcohol in the gastrointestinal tract and promoting the metabolism of alcohol in the liver.

OBJECTIVETo evaluate the outcome of Titanium elastic intramedullary nailing (TEN) for the treatment of displaced midclavicular fractures.

METHODSBetween February 2010 and February 2013, 62 patients with displaced midclavicular fractures were treated by TEN, including 27 males and 35 females with an average age of 37.6 years old ranging from 15 to 67 years. The course of disease was from 1 to 9 days (means 2.7 days). Thirty-nine cases were treated by closed reduction and 23 cases by assistant small incision. Based on OTA (the Orthopaedic Trauma Association classification) classification, 31 cases of simple fractures involved 5 cases of 06-A1,15 cases of 06-A2,11 cases of 06-A3; 31 cases of wedge fractures involved 4 cases of 06-B1,12 cases of 06-B2,15 cases of 06-B3. Postoperative pain relief were evaluated by VAS score,and operation time,fracture healing time were recorded. After 6 weeks and after removing internal fixation shoulder joint function was evaluated by Constant score, and shoulder joint function were assessed by Herscovici score after 6 weeks.

RESULTSExcept 2 cases were lost to follow-up, 2 cases did not remove internal fixation, 3 cases' fractures were nonunion, the remaining 55 patients received follow-up for an average time of 11.4 months. The average preoperative VAS score was 5.20±0.71, and it turned to be 1.550.59 at 3 days after operation. The average operative duration was 40 min (15 to 65 min). The average bone healing time was (2.71±0.54) months (2 to 5 months). No difference about bone healing time was found between simple fractures and wedge fractures,and between the patients treated by closed reduction and assistant small incision. According to Herscovici standard, the shoulder function was excellent in 49 cases, good in 4, fair in 1, and poor in 1. Simple fractures achieved better Constant score than wedge fractures at 6 weeks postoperatively, whereas no difference was found at 4 weeks after fixation removal.

CONCLUSIONTitanium elastic nails (TEN) for treatment of displaced midclavicular fractures has advantages of good clinical effect,rapid pain relief,fast recovery of shoulder joint function. For OTA classification type B patients with comminuted fracture can replace steel to achieve very good effect, but to grasp the appropriate.

Multilocus sequence typing (MLST) is a molecular genotyping method based on nucleotide sequencing. The procedure of this method characterizes isolates of bacterial species using the DNA sequencing of multiple housekeeping genes(usually seven). For each housekeeping gene, the different sequences present within a bacterial species are assigned as distinct alleles.For each isolate, the alleles at each of the loci define the allelic profile or sequence type (ST). MLST has the advantages of being robust (based on genetic data) and electronically portable to generate data that allow rapid and global comparisons between different laboratories. In this paper, the principle, method, data analysis, application, advantages and flaws of MLST are introduced.

OBJECTIVETo evaluate the clinical efficacy and efficacy sustainable time of acupuncture in knee osteoarthritis (KOA).

METHODSThe non-randomized concurrent control trial was adopted. One hundred and ninety-three cases of KOA were divided into an immediate acupuncture group (group A, 97 cases) and a delayed acupunc-weeks at the end of treatment. In group B, the same acupuncture therapy was applied after waiting 4 weeks. The acupoints in the two groups were Liangqiu (ST 34), Dubi (ST 35), Zusanli (ST 36), Yanglingquan (GB 34), Yinlingquan (SP 9), Xuehai (SP 10), Xiyan (EX-LE 4), Xiyangguan (GB 33). WOMAC (Western Ontario and McMasters Universities Osteoarthritis) was used for the assessment of the primary index and VAS (visual analogue scale) was for the secondary index. The evaluation was accomplished by the patients at the beginning of trial, on the 4th and 8th weeks. In each group, 72 patients finished the trial and the data of the lost cases were included in the final data analysis.

RESULTSIn the 4th week of trial, WOMAC score was (25. 8+/-22.0) in group A difference (P<0. 001). VAS scorewas (31. 8+/-24. and was (43.8+/-22.2) in group B, indicating the significant 6) in group A and was (56. 6 +/-25. 8) in group B, indicating very significant difference (P<0. 001). In the 8th week, the efficacy was reduced slightly in the follow-up of group A, but it was improved apparently as compared Acupuncture relieves joint pain and improves joint function obviously.by th patiĩeffr,a Mtaetfti-?an tf ri-with that before treatment.

CONCLUSIONAcupuncture relieves joint pain and improves joint function obviously.The effect of acupuncture is still sustainable in 4 weeks after terminating the treatment.

OBJECTIVEThis study examined the biochemical metabolism by proton magnetic resonance spectroscopy ('H-MRS) in order to explore the value of 'H-MRS in idiopathic epilepsy in children.

METHODSThirty-three children with idiopathic epilepsy (14 cases with history of febrile seizures and 19 cases without) and six normal controls experienced MRI of the skull and brain and single-voxel 'H-MRS examinations of the hippocampi-temporal lobe. The signal intensities of N-acetylaspartate (NAA), eatine+phosphocreatine (Cr), choline-containing compounds (Cho) and lactate (Lac) and the ratios of NAA/ (Cho+Cr) and Lac/Cr were compared between the patients and normal controls.

RESULTSMRI examination showed that only one child with epilepsy had myelin dysplasia. 'H-MRS examination showed that the ratio of NAA/ (Cho+Cr) in the epilepsy group was lower than that in the control group (0.64+/-0.07 vs 0.73+/-0.05; P<0.01). The epileptic children with history of febrile seizures had a more decreased ratio of NAA/ (Cho+Cr) compared with those without the history (0.61+/-0.07 vs 0.66+/-0.06; P<0.05). There were no significant differences in the ratio of Lac/Cr between the epilepsy and the control groups.

CONCLUSIONS'H-MRS may provide early information on brain injury sensitively and non-invasively in children with epilepsy. It may be used for diagnosis and prognosis evaluation of epilepsy.

OBJECTIVETo investigate the association between the morphological features of biopsy-diagnosed high grade intraepithelial neoplasia in the gastric mucosa and the postoperative pathology.

METHODSFifty-one patients with biopsy-diagnosed high grade intraepithelial neoplasia in the gastric mucosa were retrospectively analyzed. Thirty-three patients underwent surgery. The morphology of lesions under endoscopy and histopathological findings of the surgical specimens were investigated.

RESULTSOf the 51 patients, 43 had superficial lesions similar to early gastric cancer under endoscopy, 8 were similar to advanced carcinoma. In the 33 surgical cases, high grade intraepithelial neoplasia of gastric mucosa was confirmed on postoperative pathological examination in 13 (39.4%) patients, adenocarcinoma was identified in the remaining 20 patients (60.6%), including 14 early gastric cancers and 6 advanced carcinomas. Thirteen cases with high grade intraepithelial neoplasia confirmed postoperatively were superficial elevated or flat lesions less than 20 mm.

CONCLUSIONSPatients with biopsy-diagnosed high grade intraepithelial neoplasia in the gastric mucosa have a high risk of cancer. Thus aggressive follow-up and appropriate surgical interventions are recommended to avoid misdiagnosis.
