Acetyl-CoA C-acetyltransferase (AACT) is the first enzyme in the terpene synthesis pathway, catalyzed two units of acetyl-CoA to acetoacetyl-CoA. In order to study the tanshinone biosynthesis in Salvia miltiorrhiza, a novel AACT gene, SmAACT, was cloned using cDNA microarray and RACE strategy. The full length cDNA of SmAACT is 1 623 bp (accession No. EF635969), which contained a 1 200 bp open reading frame (ORF) encoding a 399 amino acid protein. Nine introns were found in the genomic sequence. SmAACT was upregulated by YE and Ag+ elicitors both with cDNA microarray and quantitative RT-PCR analyses along with the accumulation of tanshinones. Sequence homology comparison and phylogenetic analysis all suggested that SmAACT belonged to the class of acetyl-CoA C-acetyltransferase. The transcription level of SmAACT was relatively higher in root than that in stem and leaf tissues. SNP analysis revealed that SmAACT was highly variable in the region of 6 to 9 introns with 33 SNPs in the 600 bp region, there are 5 SNPs in the cDNA region while they are all synonymous cSNPs. Some special genotypes were found in Salvia miltiorrhiza from different areas. SmAACT will be an useful gene for further analyze the mechanism of gene regulation among the tanshinones biosynthesis.

The purpose of the present study is to establish a rapid and effective PCR method for the identification of B. multicinctus. Based on sequence alignment of B. multicinctus and its adulterants, we found that Cyt b gene is a good molecular genetic marker for the authentication of B. multicinctus. On the basis of the sequence data, a pair of highly specialized primers was designed. The templates were extracted by the DNA purification system. Key factors such as annealing temperature, concentration of Taq enzyme and cycle numbers were analyzed and optimized. The modified PCR program consisted of an initial denaturation step at 95 degrees C for 5 min, followed by 30 cycles of 95 degrees C for 30 s and 55 degrees C for 45 s and a final extension at 72 degrees C for 5 min. Thirteen samples of B. multicinctus were identified accurately from their 20 adulterants in 4 hours. The results indicated it is a highly accurate, rapid and applicable method for the authentication of B. multicinctus.

ObjectiveTo analysis the clinic outcome(similarities & differences, indication and caution)of repairing fingertip soft tissue defect with two kind of reverse digital artery island flaps with the palmar cutaneous branch of proper digital nerve.MethodsFrom January 2000 to Auguest 2008, all 500cases (514 fingers) were repaired with reverse homodigital artery island flap (263 fingers of 250 cases) and reverse cross finger digital artery island flap(251 fingers of 250 cases).All cases were followed up from 3-8years,compared with flap range,finger extension,sensory rehabilitation,et al. ResultsAll flaps (A & Bgroup) of 500 cases (514 fingers) survived.According to flap range,cross finger flap was better than homodigital flap (P < 0.05); according to finger extension,homodigital flap better than cross finger flap (P <0.05); according to sensory rehabilitation,homodigital flap little better than cross finger flap(P < 0.05); according to long-term follow-up, all had no obviously different (P > 0.05).ConclusionHomodigital flap can cover distal soft tissue defect less than 2.0 cm× 2.5 cm, cross finger flap is a better choice for more than 2.0cm×3.0cm of distal soft tissue defect. According to the flap cover area, cross finger flap is first choice,and to finger extension & sensory rehabilitation,homodigital flap is first choice; accoding to finger movements,two kinds of flaps are all good choice.

BACKGROUND: Infrared spectrum technology has potential and important value of application in diagnosing disease and analyzing pathology, as well as providing references for proper treatment. OBJECTIVE: To analyze the distinctive pathological information in the spectrums of infrared radiation at Neiguan (PC 6) acupoint of patients with coronary atherosclerotic heart disease (CAHD). DESIGN: Case-control study.SETFING: Longhua Hospital Affiliated to Shanghai University of Traditional Chinese Medicine. PARTICIPANTS: The study was conducted from April 2003 to April 2005 in patients with CAHD from Out-Patient Clinic in Longhua Hospital (21 males and 29 females, averagely 58.1 years). Forty-seven healthy volunteers were all from advertisement (25 males and 22 females, averagely 50.6 years). All the subjects were voluntary. METHODS: PHE201, a high-sensitive infrared spectrum detective device (Shanghai Institute of Technical Physics of Chinese Academy of Sciences, China) was applied to detect the spectrums of infrared radiation at Neiguan in 50 patients with CAHD and 47 healthy adults were selected as control for comparison. The scanning range was from 1.5μ m to 16μ m,73 detected wavelength spots were scanned at Neiguan of all the subjects, and the scanning spacing was 0.2μ m. MAIN OUTCOME MEASURES: Intensity of infrared radiation at Neiguan between CAHD patients and normal controls at different wavelengths. RESULTS: The intensities of infrared radiation of CAHD patients were significantly different from that of the healthy volunteers at 32 spots of the right Neiguan as well as at 23 spots of the left Neiguan among the 73 detected wavelength spots(P < 0.05-0.001). At 2-2.5μ m wavelength spots that were related to the energy metabolism, the intensities of infrared radiation of CAHD patients were significantly lower than the healthy volunteers (P < 0.05-0.005). Concerning the difference in intensities of infrared radiation between the left and the right Neiguan, the CAHD patients had more wavelength spots than healthy volunteers did (P < 0.001). CONCLUSION: ①Distinctive pathological information exists in the infrared spectrums at Neiguan in CAHD patients. ②CAHD patients have hypo-activities of energy metabolism and hypo-function ofqi and blood in the area of Neiguan.

OBJECTIVE: To observe the effect of infrared laser stimulation on Neiguan (PC 6) for bradycardia of rabbits induced by injection of pituitrin. METHODS: 10.6 microm CO(2) infrared laser, 650 nm semiconductor red laser and the compound laser of their aggregation were sent out by a compound laser sanatory instrument to stimulate Neiguan (PC 6) respectively for the purpose of analyzing the differences of the effects exerted by infrared laser and red laser as well as the changes of the effects after their aggregation. RESULTS: After 30 min and 40 min of the injection of pituitrin, the heart rate showed no significant difference between 10.6 microm CO(2) infrared laser group and the normal control group (P>0.05). However, the heart rate showed significant difference between the 650 nm semiconductor red laser group and the normal control group (P<0.05). After 30 min of the injection of pituitrin, the heart rate of the compound laser group were significantly different to that of the untreated group (P<0.05), and it was not significantly different to that of the normal control group (P>0.05). However, the heart rate of non-acupoint stimulated by the compound laser group showed no significant difference to that of the untreated group (P>0.05), and it was significantly different to that of the normal control group (P<0.05). CONCLUSION: Stimulation on Neiguan with 10.6 microm CO(2) infrared laser can evidently improve the bradycardia induced by injection of pituitrin, while the 650 nm semiconductor red laser has no such function, but they have coordinating effect. The thermal effect produced by CO(2) infrared laser stimulating acupoint is probably beneficial for semiconductor laser penetrating skin as well as the biochemical reactions it carries. The improvement of heart rate produced by the laser stimulation on Neiguan (PC 6) has relative specificity.
