This paper aimed to investigate the botanical origins of Isatidis Radix and Isatidis Folium, and clarify the confusion of its classification. The second internal transcribed spacer (ITS2) of ribosomal DNA, the chloroplast matK gene of 22 samples from some major production areas were amplified and sequenced. Sequence assembly and consensus sequence generation were performed using the CodonCode Aligner. Phylogenetic study was performed using MEGA 4.0 software in accordance with the Kimura 2-Parameter (K2P) model, and the phylogenetic tree was constructed using the neighbor-joining methods. The results showed that the length of ITS2 sequence of the botanical origins of Isatidis Radix and Isatidis Folium was 191 bp. The sequence showed that some samples had several SNP sites, and some samples had heterozygosis sites. In the NJ tree, based on ITS2 sequence, the studied samples were separated into two groups, and one of them was gathered with Isatis tinctoria L. The studied samples also were divided into two groups obviously based on the chloroplast matK gene. In conclusion, our results support that the botanical origins of Isatidis Radix and Isatidis Folium are Isatis indigotica Fortune, and Isatis indigotica and Isatis tinctoria are two distinct species. This study doesn't support the opinion about the combination of these two species in Flora of China.

Objective To observe the expression of leukocyte-function-associated antigen-1(LFA-1)immunoreaction in children with febrile seizures(FS),and explore the neuroimmunomodulation mechanisms in the pathogenesis of FS.Methods Adopting flow cytometry(FCM),the levels of LFA-1 contained in blood serum and peripheral blood mononuclear cells(PBMC)of 60 cases [simple FS(SFS)30 cases;complex FS(CFS)30 cases] with febrile convulsion were analyzed,and compared with those in a normal group(30 cases).Out of 60 children with FS group,the LFA-1 mRNA in 20 cases with SFS and 20 cases with CFS was analyzed,and LFA-1 mRNA in19 health children taken out from control group(30 cases)was analyzed.The real-time PCR was used to detect the expression of PBMC LFA-1 mRNA.Results The expression of LFA-1 in the surface of PBMC of the 3 groups,the highest LFA-1 level was in the SFS group(50.89?21.36),the lowest LFA-1 level was in the CFS group(34.35?11.45),and control group was(41.39?16.30).Significant differences were found in 3 groups(Pa

OBJECTIVETo investigate the change of JNK and c-Jun in lung injury associated with paraquat poisoning of rats.

METHODS46 Rats were randomly divided into four groups: PQ group (n = 12), control group (n = 10), PQ + ZnPP group (n = 12) and PQ + Hm group (n = 12). The rats were injected with 2% PQ (25 mg/kg, ip) in PQ group. ZnPP and Hemin (10 mg/kg, 10 mg/ml) were injected through inguinal vein before intraperitoneal administration of 2% paraquat in PQ + ZnPP group and PQ + Hm group respectively. The rats were injected NS (1 ml/kg, ip) in control group. HE dyeing of lung tissue and MDA content of plasma were used for estimating the injury of lung tissue. The content of CO in the lung tissue was determined. The expression of HO-1 mRNA of the lung tissue was detected by the reverse transcription-polymerase chain reaction. The phosphorylation of JNK and c-Jun was evaluated by Western blot analysis.

RESULTSThe degree of lung injury in PQ group and PQ + ZnPP group was higher than that in control group and PQ + Hm group. But in PQ + Hm group the degree of lung injury was lower. The content of MDA in PQ group and PQ + ZnPP group was higher than that in control group and PQ + Hm group (P < 0.01). The content of MDA in PQ + Hm group was higher than that in control group (P < 0.05). The content of CO in lung tissue in PQ group, PQ + ZnPP group and PQ + Hm group was and (1.08 +/- 0.15 mg/L) respectively, and higher than that in control group (P < 0.01). The content of CO in lung tissue in PQ + Hm group was significantly higher than that in PQ + ZnPP group (P < 0.01). The expression of HO-1 and the phosphorylation of JNK (55.24 +/- 9.34, 38.15 +/- 10.71, 128.55 +/- 19.43) and c-Jun (23.16 +/- 4.85, 15.49 +/- 3.13, 44.89 +/- 10.37) were increased remarkably in PQ group, PQ + ZnPP group and PQ + Hm group. Those in PQ + Hm group were higher significantly than PQ group and PQ + ZnPP group (P < 0.01). Those in PQ + ZnPP group were lower than PQ group (P < 0.05).

CONCLUSIONThe increase of CO of lung tissue in rats at the lung injury associated with paraquat poisoning reduces the acute lung injury of rats. The level of JNK and c-Jun phosphorylation increases obviously, especially after Hemin is utilized.

AIM:To study the feasibility of recombinant adeno-associated virus(rAAV)as a vector to transfer the green fluorescent protein(GFP)gene as a target gene into rabbit retina.METHODS:Intravitreal injection of rAAV-gfp was performed in either eye for each rabbit with the other eye taken as control.At the 3rd,7th,and 14th day after injection,the eyeballs were removed,and the retinas were flat-mounted on glass slides to inspect the retinal fluorescence,respectively.RESULTS:After intravitreal injection of rAAV-gfp,the presence of fluorescent spots in the cytoplasm of retinal cells indicated that GFP gene was efficiently transferred and expressed in the rabbit retina.CONCLUSION:Recombinant adeno-associated virus is a reliable and simple vector for transferring target gene,e.g.,GFP gene,to the retina.

In drowning cases, it is difficult to judge whether the deceased died from drowning or throwing into the water after killed or identificate the cause of death of the decomposed corps in forensic practices. The diatom test is still considered as the important assistant evidence in drowning cases. This paper reviews research progress on technologies in recent years of forensic diatom test, and the application value of the new developing approach in the field of forensic medicine.
