ObjectiveTo investigate the loss of heterozygosity (LOH) on 6q in bladder tumor.MethodsD6S404 and D6434 microsatellite markers near 6q21 were tested by PCR-SSLP-stain method on tumor DNA from 31 cases of bladder tumor.ResultsAmong these 31 cases of bladder tumor,LOH was detected in tumor tissues on site for D6S404 (35.5%) and D6S434(22.6%).ConclusionOne or more tumor suppressor gene near 6q21 maybe relevant for the development of bladder tumor.

OBJECTIVE: The study was carried out on application of CODIS loci (FGA, vWA, CSF1PO, TH01, TPOX, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51 and D21S11) in 100 cases of excluding paternity. METHODS: The PCR amplified products of Profiler Plus and Cofiler amplification kit were injected into a capillary on the ABI PRISM 310 Genetic Analyzer. GeneScan software analyzed the collected data, which can then be imported into Genotyper software for genotyping of alleles. RESULTS: In the group of Mother-Child-Alleged Father, more than 3 STR loci incompatibilities between alleged father and child were found in all observed cases, the mean incompatibility was 6.63; In the group of Alleged Father-Child, 94.0% of all cases observed was found more than 3 STR loci incompatibilities, the mean incompatibility was 5.01. CONCLUSION The results showed that CODIS loci had good application to excluding paternity, and the choice of hyperpolymorphic markers in investigation, which were valued by DP, H and PE, had direct relation with the augmentation of incompatibilities in excluding paternity.

OBJECTIVE: The study was carried out on the evaluation of number and value of STR loci applied in paternity identification. METHODS: A total of 13 STR loci, divided into four groups, was observed in 102 cases of paternity exclusion and 100 cases of paternity inclusion. PCR amplified products of 13 STR loci were injected into a capillary on the ABI PRISM 310 Genetic Analyzer. GeneScan software analyzed the collected data, which can then be imported into Genotyper software for genotyping of alleles. RESULTS: At least 3 STR loci incompatibilities between alleged father and child were found in all paternity exclusion cases of two observed groups which Cumulative Probability of Exclusion (CPE) was more than 99.99%, and in all paternity inclusion cases of those same observed groups, their Relative Chance of Paternity(RCP) could be over 99.99%. CONCLUSION The exclusion of paternity should be based on at least three STR loci incompatibilities in the identification practice. As a criterion for evaluation of the number and value of STR loci applied in paternity test, CPE should reach 99.99%.

Objective To investigate the risk factors of perivascular space change after brain tumor surgery.Methods According to the occurrence of postoperative perivascular space change,80 cases of glioma patients were divided into perivascular space and reconstruction group(observation group,n=38)and normal postoperative perivascular space group(control group,n=42).Compared the general data,sur-gery,tumor related indicators and postoperative complications of the two groups,and analyzed the influencing factors of the perivascular space changes after brain tumor surgery.Results In the observation group,the operation time of the patients was(95.38 ±9.21)min,which was significantly longer than(75.36 ±9.05)min in the control group.The intraoperative blood loss was(290.32 ±45.47)mL in the observation group,which was significantly more than(247.19 ±36.75)mL in the control group,and the difference was statistically significant (P<0.05).The tumor site located in the left hemisphere,tumor volume more than 40.0 cm3,high grade glioma,and proportion of patients with postoperative complications in the observation group were all higher than those of the control group,and the difference between the two groups was statistically significant(P<0.05).Multivariate Logistic regression analysis showed that age,tumor location,tumor volume,patho-logical grade and complications were significantly correlated with the changes of perivascular space after surgery(P<0.05).Conclusion Advanced age,tumor located in the left side of the brain,large tumor volume,severe pathology,postoperative epilepsy,chronic intracranial hy-pertension and other complications were the risk factors affecting the changes of perivascular space in patients with glioma.

OBJECTIVETo study the effects of Liangge San to the expression of CD14 and scaverger receptor(SR) in the kupffer cells of liver and the pathological changes of liver tissue of endotoxemia-mice.

METHODThe model was established with intravenous injection of lipopolysaccharide (LPS) and at the same time different dose Liangge San were given. The expression of CD14 and scaverger receptor were detected with immunohigtochemistry at the 2nd, 4th, 8th hour ofter injury and analyzed with computer image system, and the pathological changes of liver tissue were also observed.

RESULTAt the three different hours, the expression of CD14 and scaverger receptor in macrophages of liver of LPS-injury group showed significant increase and significant decrease respectively, compared with that of the blank-control group (P < 0.01). The expression in dexamethasone group and Liangge San different dose groups were intermediate between those in injury group and those in control group. Compared with expression of LPS-injury group, those of dexamethasone group and Liangge San different dose groups showed significant differences (P < 0.01), especially that of Liangge San high dose group. Liver cells showed vacuole change. Changes of CD14 and SR expression were paralleled with the severity of liver damages of the mice.

CONCLUSIONLiangge San can inhibite the up-regulation of CD14 expression and down-regulation of scaverger receptor expression in a dosage-dependent manner and also alleviate the damages of liver induced by LPS.

OBJECTIVETo detect the expression and distribution of metallothionein 2 (MT-2) in middle ear cholesteatoma, and to explore the relationship of MT-2 with interleukin 1α (IL-1α) and interleukin 6 (IL-6), and well as to explore the role of MT-2 in the pathogenetic mechanism of middle ear cholesteatoma.

METHODSUsing the immunohistochemistry and reverse transcription polymerase chain reaction to examine the expressions of MT-2, IL-1α and IL-6 protein and MT-2 mRNA in twenty-five middle ears' cholesteatoma and seven normal external ears' canal skin. The influence of cholesteatoma debris on the MT-2 mRNA and protein of HaCaT cell were further analyzed.

RESULTSAccording to immunohistochemistry research, the expressions of MT-2, IL-1α and IL-6 were extremely higher in middle ear cholesteatoma than those in normal external ears' canal skin (P < 0.05). The result of RT-PCR showed that there was significant difference between the expression of MT-2 mRNA of and middle ear cholesteatoma than those in normal external ear canal skin (t = 15.38, P < 0.05). There was a positive correlation between the expression of MT-2 and that of IL-1α (r = 0.856, P < 0.05). There was also positive correlation between the expression of MT-2 and that of IL-6 (r = 0.714, P < 0.05). MT-2 mRNA and protein of HaCaT cell significantly increased when exposed to cholesteatoma debris in a dose dependent manner.

CONCLUSIONSMT-2, IL-1α and IL-6 may play an important role in the pathogenetic process of middle ear cholesteatoma. Cholesteatoma debris may involve in the proliferation of middle ear cholesteatoma by activation of MT-2.

OBJECTIVETo investigate the influence of tinnitus frequency on medication and prognosis in patients with chronic subjective tinnitus.

METHODSSeventy-two patients (Ninety-three ears) diagnosed as chronic subjective tinnitus were studied from October 2010 to March 2011. All cases were divided into low frequency(twenty-three ears), medium frequency(fourteen ears) and high frequency (fifty-six ears) according to tinnitus matching test. All cases were treated with microcirculation promotion and steroid therapy (5% glucose 250 ml + ginkgo biloba extract 87.5 mg + dexamethasone 10 mg intravenous drip). Curative effect was evaluated and the factors of prognosis were analyzed after three weeks.

RESULTSAfter medication, results were acquired as follows: recovery in 0 ear (0%), excellent in 0 ear (0%), effective in 18 ears (19.4%), invalid in 75 ear (80.6%). The effective percentage was 39.1%, 35.7% and 7.1%, respectively. There was significant difference between these groups, but no significant difference between low frequency and medium frequency. Logistic regression analysis showed that the difference of frequency was significant prognostic factors for medication.

CONCLUSIONSMicrocirculation promotion and steroid therapy had a poor treatment effect in patients with chronic subjective tinnitus. The prognosis of chronic low-medium frequency tinnitus was better than chronic high frequency tinnitus. The difference of frequency retained significant influence on effects and prognosis of medication.
