Objective To study the clinical significance of urinary mtcroprotems examination on early diagnosis of kidney damage of children with obesity. Method Urinary microproteins were tested in 40 obese children by enzyme - linked immunosorbent assay and 50 healthy children as controls. Results Urinary microprotem examination were abnormal in 8 obese children. Albumin in 5 cases increased, and transferrin(TRF) with retinol-binding protein in 1 case increased meanwhile. TRF in 3 cases increased. One case was abnormal by kidney biopsy.Conclusion Urinary microprotem examination was the sensitive index in early diagnosis of obesity-related glomerulopathy in children.

Objective To evaluate the significance of the panel of 6 microsatellites in detection of bladder cancer. Methods In the tumor tissue and urine sediment of 32 cases of bladder cancer 10 microsatellites were chosen and PCR-SSLP silver staining assay was conducted according to the methods described in the literature and our previous study.15 cases of non-bladder cancer served as controls. Results Microsatellite alternate (MA) was found in 30 out of 32 cases of bladder cancers,the sensitivity being 93.8%.The MA of urine sediment of 15 cases of non-bladder cancer was negative,the specifity being 100.0%.Among the 10 microsatellites, 6 ones were chosen;the MA positivity of the panel of the 6 ones was 90.6% (29/32).This result was not significantly different from that of the panel of 10 microsatellites. Conclusions MA assay is a sensitive,effective method for detection of bladder cancer.Compared with the panel of 10 microsatellites,the panel of 6 microsatellites may be a better tool for detection of bladder cancer.

Objective To develop an assay method for quantitative analysis of cocaine in rat's serum by high-performance liquid chromatography (HPLC). Method Serum samples (30?l) were extracted with 2% isoamyl alcohol and hexane. The organic phase was extracted with 0.1 mol/L HC1. The quantitative analysis was achieved by using a 5?m reversed-phase Kromasil CIS column with mobile phase of 0.04mol/ L phosphate buffer solution (containing 0.26 mmol/L tetrabutylammonium chloride , pH3.2) - acetonitrile (83:17). The wave length of the ultraviolet detection was performed at 235nm. Results The lowest limit of the detection limit was 25ng/ml. The recovery of the cocaine was 71 %. Conclusion The method is sensitive, simple and easy to perform.

The mature seeds and excised embryos of Dalbergia odorifera were used as materials to study the effect of moisture content on their survival, as well as the effect of rapid freezing and vitrification freezing method on seeds and in vitro embryos cryopreservation. The results showed that the germination rate and vigor decreased from 82.67%, 85% to 18.35%, 25% respectively, when the seed moisture content decreased from 15.04% to 8.14%; and the germination rate decreased from 82.67% to 37.50%, 25.37% respectively by vitrification freezing method and rapid freezing method, when the seed moisture content decreased from 15.04% to 9.37%. Among all the moisture content gradient, 12.35% moisture reached the maximal germination rate, which were 63.58% and 50.45% respectively by vitrification freezing and rapid freezing; and when the embryo moisture content was 26.32%, the germination rate decreased from 95.67% to 58.31% and 33.82% respectively by vitrification freezing and rapid freezing. And when the moisture content was in the range of 14.17% -21.34%, the germination rate was a bit of decrease. The experiment results showed that the optimum conditions of seed cryopreservation were: moisture content 12.35%, vitrification freezing; and the optimum conditions of in vitro embryo cryopreservation were: moisture 15.04%, vitrification freezing. In conclusion, the effects of moisture content on germination rate after cryopreservation in D. odorifera seeds and embryo were significant, and vitrification freezing method is much better than rapid freezing method.

Objective To investigate the possibility of microsatellite alteration (MA) in diagnosis of bladder cancer of Chinese people, and find the better panel which will be used in clinic. Methods A total of 6 and 10microsatellite markers were chosen, PCR-SSLP silver staining assay was performed in 31 and 32 bladder cancers tissue,exfoliate cells in urine and 10, 15 non-bladder cancers exfoliate cells in urine, respectively. Results MA (+) was found in 28 out of 31, 30 out of 32 bladder cancers, and the sensitivity was 90.3%, 93.7% respectively. The MA of urine sediment of 25 non-bladder cancers was negative, and the specificity was 100%. The cytology was carried out among 19 out of 31, 20 out of 32 bladder cancers at the same time, 2 cases ( 10.3 %) and 3 cases ( 15 % ) were found cancer positive, and the sensitivity is significantly lower than that by the analysis of MA in exfoliated cells. Conclusion MA was not associated with grade and stage of the bladder cancer. MA assay is a sensitive and effective method for the early detection of bladder cancer and post-operation surveillance.

AIM: To investigate the pharmacodynamic effects of Huahong Capsule on the anti-bacteria,anti-inflammation,antipyretic and analgesic effects. METHODS: The death rate of mice infected by staphylococcus aureus or Escherichia coli was observed to investigate the antibacterial effects.Crotonoil-induced auricle edema,cotton ball-induced granuloma and trauma-induced toe congestion were performed to investigate the anti-inflammatory effects in mice.Endotoxin-induced fever was performed to observe the antipyretic effect in rabbit.Mouse twisting numbers induced by acetic acid,mouse pain threshold after heat stimulation and rat twisting numbers of dysmenorrhea were observed to investigate the analgesic effects. RESULTS: Huahong Capsule had a tendency to decrease the death rate of mice infected by bacteria.It could remarkably inhibit edema of auricle of ear,formation of granuloma and toe congestion in mice.It decreased obviously the temperature raised by endotoxin in rabbit.It could reduce mouse twisting numbers and prolong pain thresholds. CONCLUSION: Huahong Capsule has pharmacological effects in accordance with its clinical functions and uses.

Objective To investigate the influence of CD4+CD25+ regulatory T cells (Tregs) on the disease progression in MRL/lps mice. Methods Tregs were separated by using magnetic beads from splenic cells of MRL/lps mice and BALB/c mice, and concentrated. Twenty-four MRLAps mice were equally divided into 3 groups, test group 1 injected with Tregs from MRL/lps mice, test group 2 injected with Tregs from BALB/c mice, and control group injected with physiological sodium chloride solution. Three weeks later, the levels of urine protein as well as serum anti-dsDNA antibody were determined; subsequently, the mice were sacrificed followed by histopathological and immunopathological examination of renal tissue. Results A significant decline was observed in the test group 1 compared with the test group 2 and control group in the urine protein score (10.63 ± 4.17 vs. 20.00 ± 5.35 and 18.75 ± 8.34, both P < 0.05), serum anti-dsDNA antibody level (5.36 ± 2.40 pg/ml vs. 9.57 ± 1.97 pg/ml and 10.75 ± 3.98 pg/ml, both P < 0.05), glomerular sclerosis index [(32.00 ± 12.09)% vs. (45.50 ± 13.68)% and (47.50 ± 10.78)%, both P< 0.05], and immunofluorescence intensity of IgG immune complex in renal tissue (1.88 ± 0.99 vs. 2.88 ± 0.64 and 2.75 ± 0.71, both P< 0.05). No significant difference was noted in renal tubule interstitial impairment index between the 3 groups (4.63 ± 1.92, 6.00 ± 1.07 and 5.75 ± 1.28, all P> 0.05). There was no statistical difference between the test group 2 and control group in terms of any of the above parameters (all P > 0.05). Conclusions Injection of Tregs from homologous mice could significantly down-regulate proteinuria degree, serum anti-dsDNA antibody level, glomerular sclerosis index and IgG immune complex level in renal tissue, and thereby decelerate the progression of renal impairment in MRL/lps mice.

ObjectiveTo investigate the effect of speech therapy on mental health of patients with aphasia. MethodsCRRCAE and SCL-90 were used to assess the speech and mental state in 28 aphasia patients. All aphasia patients were treated by using speech therapy and the changes before and after treatment were compared. ResultsThe scores in listening comprehension, repetition, naming, reading,reading comprehension, writing and counting were distinctly higher at post-treatment than that at pre-treatment. All SCL-90 factor's levels at post-treatment were distinctly reduced than that at preat post-treatment(P<0.01).Conclusions Speech therapy can improve the language function,as well as mitigate the mental symptoms.
