Objective To investigate the clinical value of individualization of transrectal ultrasound guided prostate biopsy strategies for prostate cancer detection.Methods Ninety-seven patients who were considered having prostate cancer underwent individualization prostate biopsy strategies as individualization group.Fifty-two patients who were considered having prostate cancer underwent systemic 6-core prostate biopsy as control group.The detection rate of prostate cancer and rate of complications were compared between two groups.Results The detection rate of prostate cancer in individualization group was 43.3 ％(42/97),there was no significant difference in age and prostate volume between the prostate cancer patients and the non-prostate cancer patients(P＞0.05),but the prostate specific antigen(PSA)level of the prostate cancer patients was significantly higher than that of the non-prostate cancer patients[(26.4±2.9)μ g/L vs.(11.2±3.1)μ g/L,P=0.0000].The detection rate of prostate cancer in control group was 23.1％(12/52),the detection rate of prostate cancer in individualization group was significantly higher than that in control group(P=0.014).There was no significant difference in the rate of complications between two groups(P＞0.05).Conclusions The first detection rate of prostate cancer in individualization of transrectal ultrasound guided prostate biopsy strategies is higher than that by systemic 6-core prostate biopsy,and the rate of complications is not increased.The individualization of transrectal ultrasound guided prostate biopsy strategies for prostate cancer is good,safety,deserve clinical expansion.

Objective To investigate the relationship between genetic polymorphism in glutathione S-transferases T1, M1 and P1 and susceptibility to reflux esophagitis. Methods Genomic DNA was isolated from peripheral blood from the patients with reflux esophagitis (n=109), cases with negative endoscopy reflux disease (NERD) (n=97) and controls (n=97). Genes GSTM1 and GSTT1 were detected by multiplex PCR. A A→G polymorphism of codon 104 of the gene GSTP1 was detected using PCR-based restriction fragment length polymorphisms ( PCR-RFLP ) with Alw26I. Results The frequency of variant GSTP1 genotypes (*A/*B and*B/*B) was found to be 40.4% among the patients with reflux esophagitis compared with 24.7% among cases with gastroesophageal reflux without esophagitis and 21.6% among controls (P

The authors retrospectively analysed 67(63 in cervical cord)cases of traumatic SCIWOAR with positive MR abnormalities. It was deduced that the cases of SCIWOAR might be related with (1)those traumatic forces resulting in SCI being not so heavy and severe, (2)the cases orignally with cervical spondylopathy,(3)the limitation of the conventional X-ray examination for SCI,and (4)the cases of children relativly rare in our country and hospital.The ALL hematomas are the pathognomonic signs in the case of the acute cervical SCI within one week.The analysis demonstrated that MR investigation of the traumatic spine could give the clinical activities the correct diagnosis of different degree of SCI and dependable reference.

[Objective]To determine the effect of Oxfenmino hydrochloric acid on delayed allergic reaction in mouse. [ Method ] 120 ICR mice weighing 18~22g, half female and half male, were randomly and averagely divided into 6 groups according to weight:control group and model group (treated with distilled water at a dosage of 10ml/kg), three Oxfenmino hydrochloric acid groups (treated with Oxfenmino hydrochloric acid at a dosage of 10.0mg/kg, 5.0mg/kg and 2.5mg/kg respectively) and positive drug group (treated with CsA at a dosage of 15mg/kg); they were orally administered one time every day. After a continuous week of administration, all the groups were smeared evenly with 1%DNFB solution on the abdomen for allergy except the control group. Five days after allergy, 1%DNFB solution was smeared to right ear of all mice to stimulate the allergic reaction except that the control group was smeared with non-allergenic substance. 24 hours after attack, the auricle swelling, spleen index and thymus index in right mouse were determined. [ Result] Different dosages of Oxfenmino hydrochloric acid benefited to reduce auricle swelling, spleen index and thymus index in mouse with allergic reaction induced by DNFB at different degree. [ Conclusion] Oxfenmino hydrochloric acid can inhibit the delayed allergic reaction in mouse induced by DNFB and depress the ability of specific cell-mediated immunity.

A novel electrochemiluminescence ( ECL) method for the determination of L-cysteine ( L-Cys) was established. water-soluble CdS quantum dots ( QDs) with Cd2+rich surface were synthesized via a controllable one-poe approach. The mercapto group in L-cysteine molecule can specifically interact with excessive Cd2+on the surface of CdS QDs, resulting in enhancement of ECL intensity of the CdS QDs, which can be used for the detection of L-Cys. Under the optimal experimental conditions, the enhancement of ECL intensity was linear with the concentration of L-Cys in the range of 5. 0×10-9-1. 0×10-5 mol/L. The limit detection of (S/N=3) was 1. 2×10-9 mol/L. In comparison with other methods for detecting L-Cys, this method is more simple and selective, and can be applied to detect L-Cys in real sample with satisfactory results.

Objective To establish a rapid specific quantitative assay for Bacillus anthracis detection. Methods According to the principle of complex probe quantitative assay, the primers and quantitative probes targeted at chromatosome DNA rpoB were designed and applied to detect Bacillus anthracis.
