1.BIOCHANIN A PROTECTS DOPAMINERGIC NEURONS BY INHIBITING MICROGLIA ACTIVATION
Acta Nutrimenta Sinica 2004;0(06):-
Objective:To explore the protective effect of biochanin A(Bioch A) on lipopolysaccharide(LPS) -induced dopaminergic neurodegeneration. Method:An in vitro model of LPS-induced dopaminergic neurodegeneration was used to investigate the protective effect of Bioch A on dopaminergic neurons against LPS-induced neurotoxicity by measuring [3H] DA uptake and counting TH-immunoreactive cells. Microglia were visualized by staining for the CR3 complement receptor with monoclonal antibody OX-42. The production of nitric oxide(NO) was determined by measuring the accumulated levels of nitrite in the culture supernatant with the Griess reagent,and release of tumor necrosis factor-?(TNF-?) was measured by immunosorbent assay. The production of superoxide was determined by measuring the superoxide dismutase(SOD) -inhibitable reduction of cytochrome C. Results:BiochA dose-dependently attenuated LPS-induced decrease in dopamine(DA) uptake and the number of dopaminergic neurons in rat mesencephalic neuron-glia cultures. BiochA also significantly inhibited LPS-induced activation of microglia and production of TNF-?,NO and superoxide in rat mesencephalic neuron-glia cultures and microglia-enriched cultures. Conclusion:Biochanin A may protect dopaminergic neurons from LPS-induced injury and its effectiveness in inhibiting microglia activation may underlie one of the mechanisms.

ObjectiveTo evaluate the intraoperative neuromonitoring of the external branch of the superior laryngeal nerve (EBSLN) during Micooli's endoscopic thyroidectomy in order to avoid nerve injury.MethodsIn this study,36 patients with 56 nerves at risk were enrolled from February 2011 to September 2011.A positive signal is determined by observing contractions of the cricothyroid muscle to locate the EBSLN.The relationship between EBSLN and the upper pole of the thyroid or the inferior constrictor muscle was studied.The VHI-10 table was used for evaluation pre- and postoperatively. ResultsAll 56 nerves were located successfully,26 nerves(46.4% ) crossed the superior thyroid artery more than 1 cm apart from the upper pole of the thyroid gland,while the other 30 nerves(53.6% ) did less than 1 cm.In cases where the diameter was longer than 5 cm,the nerves crossed the artery at less than 1.0 cm from the upper pole in 73% cases(P =0.006).There was no significant difference between VHI-10 results before and after surgery (P > 0.05). ConclusionsIntraoperative neuromonitoring is useful and helpful in avoiding nerve injury by locating EBSLN.

In order to get more pulse diagram valuable information, we summarized the traditional acceleration in the pulse chart based on the calculation of a new high-precision calculation of the acceleration pulse graph algorithms, being suitable for a large amount of data to adapt to requirements of high-resolution digital pulse diagram analysis, optimizing the acceleration pulse mapping process, reducing the impact of noise on data analysis, and improving the ability to distinguish details of the image. In addition, we used the spectrum analysis diagram for high-precision acceleration pulse. By doing so, we overcomed the traditional acceleration noise in the pulse data as the large loss, we found flat pulse, slippery pulse, taut pulse acceleration spectrum of feature points in the new Chinese medical traditional pulses. We then were able to recognize the pulse diagram calculated at the acceleration level to identify the frequency domain.

Objective To discuss the management of renal cell carcinoma(RCC) associated with von Hippel-Lindau(VHL) disease. Methods Clinical data were analyzed retrospectively from 28 ca-ses ( 16 males and 12 females, with a mean age of 45 years), of whom 15 had bilateral RCC and 13 had unilateral RCC. VHL germline mutation was analyzed in 25 cases. Nephron sparing surgery (NSS) or radical nephrectomy was performed in 24 cases. Results VHL germline mutations were detected in 25 cases including 14 asymptomatic patients. Among 29 solid renal tumors in 9 cases observed for a mean time of 44 months (range 12 to 86), the mean increase in tumor size was 0. 531 cm/year. There were 19(65.5%) tumors>3 cm at the end of follow-up but only 1 developed retroperitoneum lymph nodes metastasis. A total of 87 solid tumors were removed and 62 (71.3%) solid tumors were man-aged by NSS. Pathological results showed 86 clear cell carcinomas (73 Fuhrman Ⅰ and 12 Fuhrman Ⅱ ) and 1 calcified lesion. During mean follow-up of 50(5-237) months, local recurrence occurred in 4 cases treated with NSS; 26 patients were alive at the end of follow-up. Conclusions DNA testing might be helpful in the earlier detection of asymptomatic VHL patients. Most solid renal tumors in VHL disease grow slowly. The majority of the tumors >3 cm may still be indolent and do not metas-tasize during longer follow-up and can be observed. NSS is effective and safe for RCC in VHL disease.

Objective:To investigate the drug resistance of Yersinia pestis to 11 kinds of antibiotics in the natural foci of plague in Inner Mongolia Autonomous Region, and to provide a theoretical basis for scientifically and effectively selecting antibiotics for treatment of the plague. Methods:A total of 137 strains of Yersinia pestis isolated from the natural foci of plague in Inner Mongolia Autonomous Region at different times, regions, hosts and vectors were collected. According to Clinical and Laboratory Standard Institute (CLSI), the agar plate dilution method was used to determine the minimum inhibitory concentration (MIC) of the 11 kinds of antibiotics against 137 strains of Yersinia pestis, including ofloxacin, ciprofloxacin, kanamycin, streptomycin, ceftriaxone, ampicillin, chloramphenicol, spectinomycin, cefuroxime, tetracycline and sulfamethoxazole-trimethoprim. The MIC 50 and MIC 90 (the minimum concentration of drug which could inhibit 50% and 90% of bacterial growth) were calculated, and their sensitivity was determined according to CLSI standards. Results:Among 137 strains of Yersinia pestis tested, no strains of Yersinia pestis had single or multiple resistance to ofloxacin, ciprofloxacin, kanamycin, streptomycin, ceftriaxone, ampicillin, chloramphenicol, spectinomycin, cefuroxime, tetracycline and sulfamethoxazole-trimethoprim. According to CLSI standards, 137 strains of Yersinia pestis were all sensitive to the 11 kinds of antibiotics; among them, ofloxacin, ciprofloxacin, ceftriaxone and sulfamethoxazole-trimethoprim had higher antibacterial activity, with MIC 90 < 0.250 μg/ ml; the antibacterial activity of spectinomycin was the lowest, with MIC 90 of 16.000 μg/ml. Conclusions:The Yersinia pestis isolated from the natural foci of plague in Inner Mongolia Autonomous Region is not found to have single or multiple resistance to the 11 kinds of antibiotics. Continuous drug resistance monitoring of Yersinia pestis should be carried out to provide a basis for clinical medication.
