Objective: To investigate the anti-oxidation activity of astaxanthin. Method: Free radical scavenging properties were investigated in modified chemical system. The antioxidation activity of astaxanthin and vitamin E for linoleic acid autooxidation, hydroxy radical and DPPH radical was detected by spectrophotometry. Results: Astaxanthin could inhibit autooxidation of linoleic acid effectively and its inhibition and elimination rate to hydroxy radical was higher than vitamin E. The elimination rate was 95.98% at the concentration of 50 ?g/ml astaxanthin. Although the effect of astaxanthin on eliminating DPPH radical was slightly lower than vitamin E, but the elimination rate still high to 97.0% at concentration of 80 ?g/ml. Conclusion: Astaxanthin has obvious anti-oxidation activity.

OBJECTIVE: By analysing the video-nystagmography findings of positional tests,to evaluate the therapeutic effect of the patients with horikontal semicircular canal cupulolithiasis (HSC-Cup). METHOD: A retrospective study of 36 patients with HSC-Cup. The induced nystagmus in roll tests was recorded by videonystagmography, whose direction, latency, intensity and time characteristics were analysed. All of the 36 patients were treated with lying position avoiding normal side and oral-taken betahistine mesilate tablets. A week later return visits and curative effects evaluation were made. RESULT: Horizontal apogeotropic nystagmus was induced by turning left or right in HSC-Cup roll tests. The time of latency and duration turning to normal and lesion side were(0. 93 ± 0. 65)s and(1. 01 ± 0. 78)s, (100.58 ± 36. 56)s and (118. 65 ± 143. 71)s, which showed no statistically significant difference (P>0. 05). The duration of nystagmus was more than 60 seconds. The intensity of nystagmus turning to normal and lesion side were(45.58 ± 28.71)°/s and (20.42 ± 16. 64)°/s. The intensity turning to normal side was greater than lesion side obviously. The difference was statistically significant (P<0. 05). Twenty-three patients withright HSC-Cup, and 13 patients with left HSC-Cup were taken in count. They were treated with above methods and return visit a week later. Twenty-eight patients (77. 77%) were cured, 36 patients (100. 00%) were improved. There were 4 patients recurrence during the follow-up. CONCLUSION The direction and duration time of induced nystagmus are available to diagnose the HSC-Cup. The lesion side may determined according to the intensity of induced nystagmus. Lying position avoiding normal side and oral-taken betahistine mesilate tablets is an effective treatment methods for HSC-Cup.

Objective:To explore the proliferation inhibition and radiosensitization of Biyanqing granule on nasopharyngeal carci -noma cell line CNE-2 in vitro.Methods:CNE-2 cells were cultured in vitro.The inhibition of Biyanqing granule on the proliferation of CNE-2 cell was evaluated by MTT assay .Radiosensitization was explored by clone formation assay , and cell cycle and apopotosis were observed by flow cytometry ( FCM) .Results:Biyanqing granule could inhibit the proliferation of CNE-2 in a time-and dose-dependent manner.The IC50 in 24, 48 and 72 h was 70.79, 60.13 and 51.63 mg· ml-1(calculated according to the weight of all medicinal ma-terial), respectively.The colony formation assay showed that Biyanqing granule combined with radiation could significantly reduce the colony formation of CNE-2 cells.With the concentration increase of the main drug , the colony formation of CNE-2 cells was reduced . The number of colony formation in the negative control group , the radiation group , 10 mg· ml-1 and 20 mg· ml-1 Biyanqing combined with radiation groups (calculated according to the weight of all medicinal material ) was significant different (P<0.05).With the main drug concentration increasing , the percentage of G 2/M phase and apoptotic cells were both increased , and compared with the con-trol group, the difference was significant (P<0.05).Conclusion:Biyanqing granule can not only inhibit CNE-2 cells but also block CNE-2 cells in G2/M to improve the radiosensitization of CNE-2 cells.

Objective To investigate the effect of meridian-unblocking and mind-regulating acupuncture pretreatment on neurobehavioral functions and cerebral water content and explore its mechanism for modulating miRNA664 and MMP9 expressions in cerebral ischemia/reperfusion rats.Methods One hundred and thirty Wistar rats were randomized into group A (electroacupuncture pretreatment) of 30 rats, group B (moxibustion pretreatment) of 30 rats, group C (aspirin pretreatment) of 30 rats, group D (model) of 30 rats and group E (blank control) of 10 rats. Group A received electroacupuncture; group B, suspended moxibustion with moxa sticks; group C, an oral gavage of aspirin 10 mg/kg. A model of cerebral ischemia/reperfusion was made in every group after seven days. Rat neurobehavioral functions were observed and cerebral water content and relative miRNA664 and MMP9 expressions in the cortical region were determined at 24 hours after reperfusion.Results There was a statistically significant difference in the neurobehavioral score between group A, B, C or D and group E (P<0.01), between group A or B and group C (P<0.01) and between groups A and B (P<0.01). There were statistically significant differences in cerebral water content and relative miRNA664 and MMP9 expressions between group A, B, C or D and group E (P<0.01,P<0.05), between group A, B or C and group D (P<0.01), between group A or B and group C (P<0.01,P<0.05) and between groups A and B (P<0.01,P<0.05).Conclusions Meridian-unblocking and mind-regulating acupuncture pretreatment can effectively decrease the neurobehavioral score and cerebral water content and reduce relative MMP9 expression through modulating miRNA664 expression in cerebral ischemia/reperfusion rats. One of the mechanisms of Du meridian-unblocking and mind-regulating acupuncture pretreatment for protecting the brain may be reducing relative MMP9 expression, inducing tolerance to cerebral ischemia and relieving cerebral edema by the modulation of miRNA664 expression.

Objective　To analyze the clinicopathologic characteristics and treatment of primary and secondary bladder mucosa lymphoma.　Methods　From June 1996 to September 2011,8 cases of bladder mucosa lymphoma patients including primary bladder mucosa lymphoma patients (2 males and 3 females)and secondary bladder mucosa lymphoma patients ( 1 male and 2 females) were treated in our institute.The patient's mean age was 68 years (ranged from 57 to 78 years),and the other 3 secondary bladder mucosa lymphoma patient's mean age was 61 years (ranged from 41 to 81 years).7 of 8 patients accepted transurethral resection of bladder tumor combined with CHOP chemotherapy and radiotherapy,and 1 patient abandoned treatment.CHOP chemotherapy and radiotherapy were performed at 2 weeks post-operatively.Secondary bladder mucosa lymphoma patients accepted 3-dimensional conformal 6000 cGy radiotherapy.Urinary CT examination showed that there were round or oval irregular tumors in the wall of urinary bladder,whose diameters were 1 to 4 cm.Tumor edges were glossy and tumor density were uniform.In addition,the bladder wall with tumor was uneven.In contrasted CT,the tumors appeared obviously enhanced.7 cases had cauliflower-like tumors found by cystoscope,and there were necrosis-calcification area in the center of tumors.1case appeared multiple tumors,which consisted of one big tumor and three smaller ones.　Results　There were 5 cases of primary bladder mucosa lymphoma, including 3 bladder mucosa associated lymphoma (MAL) cases and 2 diffuse large B cell lymphoma cases.There were 3 secondary bladder mucosa lymphoma cases including 2 diffuse large B cell lymphoma cases and 1 generalized follicular cystic central lymphoma case,which belongs to the tuberous sclerosis Hodgkin lymphoma.Immunohistochemical analysis showed that CD20,CD21,CD43 staining were positive in low grade MAL (3 cases).However,CD3,CD20,CD31 staining were positivein high grade MAL (5 cases). All patients were followed up 3 to 44 months.3 cases of secondary malignant lymphoma patients died after diagnosed after 3 to 13 months.5 cases of primary malignant lymphoma patients were all survived. 1 case recurred 14 months after surgery and accepted TURBT and CHOP chemotherapy again.Pathologic diagnosis showed the transformation from peripheral zone of bladder mucosa associated lymphoma to diffuse large B cell lymphoma.The patient was free of recurrence.　Conclusions　MAL and diffuse large B cell lymphoma are the most common type of bladder mucosa lymphoma.Primary and secondary diffuse large B cell lymphoma have similarities in histological analysis,but the former prognosis is better than the latter's. Transurethral resection of bladder tumor combined with chemotherapy and radiotherapy can prevent the relapse of MAL in short term and long term with good tolerance,and can be used as ideal treatment of MALT.

OBJECTIVETo evaluate prostate specific antigen (PSA) and transition zone index (TZI) as predictors of acute urinary retention (AUR) in men with benign prostate hyperplasia(BPH).

METHODSThe complete data of 602 cases of BPH were reviewed and analyzed.

RESULTSMean serum PSA and TZI were (6.60 +/- 3.4) microgram/L and (0.71 +/- 0.14) in AUR group, (3.51 +/- 2.3) microgram/L and (0.46 +/- 0.21) in non-AUR group, respectively. There were significant differences in serum PSA and TZI between the two groups(P < 0.05). The difference in incidence of AUR between serum PSA < 4.0 micrograms/L, 4.0-10.0 micrograms/L and PSA > 10.0 micrograms/L was significant (P < 0.05). There was significant positive correlation between serum PSA and TZI(r = 0.213, P < 0.01).

CONCLUSIONSerum PSA and TZI were powerful predictors of the risk of AUR in men with BPH.

Objective To explore the effect of Ginkgo biloba extract (EGb761) on apoptosis of K-ras mutational human colon cancer cells DLD1(DLD1/G13D)and its mechanism. Methods Human colon cancer cell lines DLD1/G13D and DLD1 with K-ras wild type(DLD1/WT)were cultured in vitro,the cell proliferation and apoptosis after 24 h of EGb761 were measured. Proteins involved in related signal pathway were detected by Western blot or ELISA. Results EGb761 reduced cell proliferation and induced cell apoptosis in a concentration-dependent manner in DLD1/WT and DLD1/G13D cells. EGb761 downregulated the expression of RIP1, impaired the phosphorylation of IκB and decreased the level of NF-κB in DLD1/WT and DLD1/G13D cells[DLD1/G13D: (24±4)%, DLD1/WT: (29±9)%(P<0.05). Conclusion EGb761 restrains the proliferation and induces the apoptosis of DLD1/WT and DLD1/G13D cells. The mechanism may be related to the degradation of RIP-1 and inhibition of activation of NF-κB signaling pathway.

OBJECTIVETo explore the mechanism of lumen loss of the left circumflex ostium after main vessel stent implantation.

METHODSTwenty-eight patients undergoing provisional T technique were enrolled in this study. Intravascular ultrasound (IVUS) examination was performed before and after main vessel stenting and kissing balloon post-dilatation to evaluate the geometrical changes of the vessels.

RESULTSThe CSA of LCX ostium lumen decreased significantly from 5.9∓2 mm(2) to 4.9∓1.9 mm(2) (P<0.01) after the procedure, and the CSA of LCX ostium P and M increased from 5.4∓2.9 mmmm(2) to 5.7∓2.9 mm(2) (P=0.21) after the main vessel stenting. The changes in LCX ostium lumen CSA was correlated with the changes of LCX ostium EEM CSA but not the LCX ostium P and M CSA. After kissing balloon post-dilatation, the CSA of LCX ostium lumen increased from 4.9∓1.9 mm(2) to 5.5∓1.9 mm(2) (P<0.01) , and the CSA of LCX ostium P and M showed no obvious changes (5.7∓2.9 mmmm(2) vs 5.7∓2.6 mmmm(2), P=0.89). The changes of LCX ostium lumen CSA were correlated with the those of the LCX ostium EEM CSA (R=0.432, P=0.02).

CONCLUSIONAfter stent implantation from the LMCA to the LAD, most of lumen losses of the LCX are due to carina shift, and in occasional cases, plaque shift occurs from the distal LMCA to the ostium of the LCX. Kissing balloon technique can adjust carina shift but can not improve plaque shift.
