The change of kirenol, darutigenol and darutoside in Siegesbeckia and its first to ninth processed products were studied, and the ten fingerprints were compared, which provided the experimental basis for the study of Siegesbeckia processing tech- nology. The samples were analysed by HPLC on a SunFire-C18 column (4.6 mm x 150 mm, 5 μm) with gradient elution of acetonitrile (0.1% formic acid)-water (0.1% formic acid) at a flow rate of 1.0 mL x min(-1). Column temperaturewas 30 °C and the detected wavelength was 215, 320 nm. The calibration curves of kirenol, darutigenol and darutoside were linear in the range of 2.180-26.16, 2.900-34.80, and 1.012-6.072 mg x L(-1), respectively, and the average recoveries were 96.4%, 97.2% and 96.3% wit RSD 2.2%, 1.7% and 2.4%. This method was simple, the result was stable and had good repeatability, recovery and precision. The re- sult was the basis of the chemical contents variation in the processing of Siegesbeckia Herbs and further clarifying the effect of the changing.

BACKGROUND: The lateral radiograph-based system described by Tsuyama is used widely to classify ossification of the posterior longitudinal ligament (OPLL) of the cervical spine. However, OPLL is a complex 3-dimensional (3-D) lesion, not a simple and uniplanar one, which is often difficult to identify on a lateral radiograph. Furthermore, its reliability among spine surgeons has not been investigated. Given the popularity of a reconstructed computed tomography (CT), this study examined the inter- and intra-observer reliability of lateral radiograph-based OPLL classification using that modality. METHODS: Five spine surgeons independently reviewed the lateral radiograph, axial CT, 2-D (sagittal) and 3-D reconstructed CT images of 108 OPLL patients on 2 separate occasions. Based on these images, the reviewers classified each OPLL case according to the Tsuyama's system. The kappa values were used to assess the statistical reliability. RESULTS: The inter- and intra-observer kappa values were only 0.51 and 0.67 for the lateral radiograph, even in combination with the axial CT images, 0.70 and 0.85 for 2-D CT images, and 0.76 and 0.86 for 3-D CT images, respectively. These kappa values showed a good-to-excellent range for the 2-D and 3-D reconstructed CT images while those of the lateral radiograph indicated a fair range. According to the OPLL types, the inter- and intra-observer reliability was low in the continuous type and high in the circumscribed type on the lateral radiograph. However, the low reliability of the continuous type on lateral radiograph was overcome somewhat using 2-D and 3-D reconstructed CT images. CONCLUSIONS: The inter- and intra-observer kappa values were only 0.51 and 0.67 for the lateral radiograph, even in combination with the axial CT images, 0.70 and 0.85 for 2-D CT images, and 0.76 and 0.86 for 3-D CT images, respectively. These kappa values showed a good-to-excellent range for the 2-D and 3-D reconstructed CT images while those of the lateral radiograph indicated a fair range. According to the OPLL types, the inter- and intra-observer reliability was low in the continuous type and high in the circumscribed type on the lateral radiograph. However, the low reliability of the continuous type on lateral radiograph was overcome somewhat using 2-D and 3-D reconstructed CT images.

OBJECTIVETo probe a better method for treatment of trigeminal neuralgia. Methods One hundred and four cases of trigeminal neuralgia were randomly divided into a treatment group (n=57) and a control group (n=47). The treatment group were treated witb acupoint injection of 2000 microg of VitB12, with Xiaguan (ST 7) selected as main point, and the control group witb oral administration of Carbamazepine. The therapeutic effect were analyzed after 3 tberapeutic courses.

RESULTSTbe cured and markedly effective rate and the effective rate were 82.5% and 98.2% in the treatment group, and 57.4% and 8O.9% in the control group, with a very significant difference between the two groups (P < 0.01). After treatment, there was a very significant difference in the cumulative score of pain between the two groups (P < 0.01).

CONCLUSIONAcupoint injection of VitB12 has a better therapeutic effect than that of oral administration of Carbamazepine.

Objective To observe the changes of serum and fecal taurine-conjugated bile acid levels and its association with glucose metabolism during the spontaneous development of type 2 diabetes in OLETO rats.Methods Twenty male OLETF rats(4 weeks old)were included and 10 male LETO rats of the same age were used as the normal control group.OLETF rats were fed with high fat diet whereas LETO rats were fed with normal diet.Serum and fecal taurine-conjugated bile acid levels of OLETF rats were tested at different stage of diabetes including baseline, normal glucose tolerance, impaired glucose tolerance and diabetes periods, and the association of taurine-conjugated bile acid level with body weight, blood glucose, and glucose-regulating hormones were also investigated.Results Compared with LETO rats, the baseline serum levels of taurine-conjugated bile acid in OLETF rats did not change, but the levels of fecal taurine-conjugated bile acid including taurine-conjugated chenodeoxycholic acid(TCDCA), taurocholic acid(TCA)and taurine-conjugated deoxycholic acid(TDCA)were significantly decreased [(14.25±7.18 vs 0.90±0.31)mg/kg,(7.12±4.14 vs 1.30±0.35)mg/kg,(4.30±1.78 vs 1.02±0.14)mg/kg, all P<0.01].During the development of diabetes, the fecal levels of TCDCA, TCA and TDCA were still lower than those in the control rats.TDCA was negatively associated with the level of fasting blood glucose(r=-0.470, P=0.032),but positively associated with the serum level of glucagon-like peptide(GLP)-l(r=0.406, P=0.044).Conclusion The decrease of intestinal taurine-conjugated bile acid level is involved in the development of diabetes in OLETF rats.Intestinal TDCA may regulate the secretion of GLP-1 by paracrine pathway.

Objective To analyse the reflection spectrum samples of three primaries (blue, red and yellow, dominating life and death) in TCM complexional inspection, and investigate the difference between life complexion and death complexion to improve the objective and systematic development of TCM complexional inspection.Methods The analysis of reflection spectrum was carried out to compare kingfisher feather, dry grass-blade, cockscomb, coagulated blood, crab abdomen, Zhishi (Fructus Aurantii Immaturus), and the apex of nose and forehead of normal person, i.e. the complexion was recorded and the characteristics were analysed by using the method of spectrum.Results The results showed that the spectrum analysis on blue (kingfisher feather), red (cockscomb) and yellow (crab abdomen), which dominated life, had unitary wave crest in reflection spectrum and vivid complexion. The spectrum analysis on blue (dry grass-blade), red (coagulated blood) and yellow (Zhishi), which dominated death, showed that the reflection spectrum was composed of multiple types of complexion (composite complexion) and the complexion was dark and gloomy. The complexion of normal person manifested faint redn and yellow, and sufficiency of qi and blood.Conclusion The correct analysis on TCM complexional inspection and identification of vivid or gloomy complexion can reflect the difference between the types of complexion dominating life and death, and improve the objective development of TCM complexional inspection.

PURPOSE: We report a rare case of ocular siderosis with delayed-onset secondary glaucoma occurring 10 years after cataract and iron foreign body removal. CASE SUMMARY: A 47-year-old male who suffered an ocular injury with an iron material to his left eye 3 years prior to his initial visit was treated in our clinic for a cataract with siderosis lentis. Ten years after he underwent cataract surgery he developed secondary open-angle glaucoma. Trabecular block taken during trabeculectomy showed no iron material, however, a fibrosclerotic change was observed. CONCLUSIONS: In patients with a history of traumatic siderosis lentis, a potential risk of siderosis remains for a long period.

PURPOSE: It is important to diagnose paragonimiasis in early active stage because it can be dured by chemotherapy. However, it is difficult to make a correct diagnosis of cerebral paragonimiasis in the early active stage, and the radiographic findings of cerebral paragonimiasis have been rarely reported. Thus, this experimental study was designed to produce early active cerebral paragonimiasis and to demonstrate radiologic-pathologic correlations. MATERIALS AND METHODS: In 8 cats, 7-8 metacercariae of Paragonimus westerrnani were directly introduced into the brain parenchyma of each cat's after trephination of the skull. In anogher 16 cats, the juvenile worms and the adult worms that had developed for varying periods (2 weeks, 4 weeks, 6 weeks, 8 weeks and 12 weeks) in the lunges of another cats were introduced into the brain parenchyma of each cat's with the same procedures described above. Follw-up MR images and chest radiographs were obtained at 2 days, 1 weeks, 2 weeks, 4 weeks and 8 weeks after innoculation. The autopsies and histopathological examinations of the cat's brain were undertaken in 22 cats. In 9 cats that were suspected with pulmonary lesions on chest radiograph, the soft tissue radiographs of inflated-fixed lungs were obtained. RESULTS: In one cat with innoculation of adult worm, acute suppurative inflammation of the brain parenchyma was demonstrated. But the other cats with innoculction of adult worm or juvenile worm and the cats with innoulation of metacercaris did not reveal any evidence of acute cerebral paragonimiasis. More than half of the introduced metacercariae(5 out of 8 cats) were found in the lung parenchyma, while only 25%(4 out of 16 cats) of the adult worm innoculated cats were. CONCLUSION: Acute suppurative inflammation suggesting acute stage cerebral paragonimiasis was obtained in one case of adult worm innoculated cat. Most of the innoculated metacercariae and some of the juvenile worms or adult worms were migrated to the lungs.

OBJECTIVES: Neurobiological models for obsessive-compulsive disorder(OCD) have consistently implicated prefrontal-striatal circuits in the pathophysiology of this disorder. But, prior studies have inconsistently found alteration in caudate and frontal lobe volumes in patients with OCD. This study was undertaken in the hope that semi-automated linear transformation methods would elucidate the morphometric differences of various parts of brain between OCD and normal control group. METHODS: Thirteen patients meeting the DSM-IV criteria for OCD, and 9 psychiatrically normal comparison subjects participated in the study. 3-D brain MRIs using Spoiled gradient-recalled (SPGR) sequence were acquired for each subjects. After spatially normalized according to Talairach and Tournoux's coordinates, the gray and white matters were segmented by semiautomated methods using fuzzy algorithm. Each lobal volumes was measured according to Talairach and Tournoux's coordinates, and the region of interests of caudate nuclei was manually traced. The frontal lobe was divided into 3 subregions; dorsolateral prefrontal cortex, orbital frontal cortex, mesial frontal cortex accoring to the coordinates and Broadman's cytoarchitectonics. RESULTS: Only the volume of left and right frontal gray matter showed a significant difference between OCD and normal subjects. In OCD, the frontal gray matter volume was increased in tendency. There's no difference in laterality and no coorelation with clinical severities. CONCLUSION: Findings of increased frontal gray matter volumes in patients implicate a structural abnormality of these brain regions in the pathophysiology of OCD. The increased frontal gray matter volumes reflect a epiphenomena due to increased cerebral blood flows and metabolic rates before the structural changes may occur.
