OBJECTIVETo observe the effect of San-huang-sheng-fu oil on wounds of full-thickness scald in rabbits.

METHODSFull-thickness scald wounds with area of 6 cm(2) were reproduced on both sides of the back in 9 experimental rabbits by water vapor. These rabbits were divided into sesame oil (S1), San-huang-sheng-fu oil (S2), and mupirocin ointment (M) groups according to the random number table, with 3 rabbits (6 wounds) in each group. Two wounds of each rabbit in the three groups were respectively treated with sesame oil, San-huang-sheng-fu oil, and mupirocin ointment, in a dose of 0.15 mL/cm(2), 2-3 times per day. The general condition of wounds was observed on post scald day (PSD) 1, 11, 22, and 45. The wound healing time was recorded. The wound healing rate was calculated on PSD 5, 11, 15, and 22. All the rabbits were sacrificed on PSD 45, and wound tissues were subjected to histomorphological study with HE staining. The protein expressions of transforming growth factor β1 (TGF-β1), basic fibroblast growth factor (bFGF), and vascular endothelial growth factor (VEGF) were observed with immunofluorescence staining for the other part of wound tissues. Data were processed with one-way analysis of variance or LSD-t test.

RESULTS(1) The wound healing quality of rabbits in S2 group was better than that in the other two groups. (2) The wound healing time of rabbits in S2 group [(11.2 ± 2.3) d] was significantly shorter than that in S1 group [(21.2 ± 3.1) d, t = 2.591, P < 0.05]. (3) The wound healing rate of rabbit in each group was increased gradually on PSD 5-22. The wound healing rates of rabbits in S2 group on PSD 5-22 were significantly higher than those in S1 group (with t values from 3.920 to 8.605, P values all below 0.05). (4) Histomorphological observation showed that the structure of wound tissues in S2 group was in much better integrity than that in the other two groups, including regenerated hair follicles in the corium layer and regularly arranged collagen fibers. The protein expressions of TGF-β1, bFGF, and VEGF in S2 group were all higher than those in the other two groups.

CONCLUSIONSSan-huang-sheng-fu oil can up-regulate the protein expressions of TGF-β1, bFGF, and VEGF, induce vascular regeneration, promote wound healing, and shorten wound healing time.

The paper is aimed to study the dynamic accumulation regulation of curcumin (Cur), demethoxycurcumin (DMC) and bisdemethoxyeurcumin (BDMC) in three strains of Curcuma longa, and provide scientific references for formalized cultivation, timely harvesting, quality control and breeding cultivation of C. longa. The accumulation regulation of the three curcumin derivatives was basically the same in rhizome of three strains. The relative contents decreased along with plant development growing, while the accumulation per hectare increased with plant development growing. The accumulation of curcuminoids per hectare could be taken as the assessment standard for the best harvest time of C. longa. A3 was the best strain in terms of Cur and BDMC content.

Psychrotrophs were isolated by using four media from low-temperature sewage of sewage treatment plant in Urumqi, Xinjiang. Totally, 154 strains were obtained including 12 filamentous fungi, 46 yeasts, 6 actinomycetes and 90 bacteria. The results of tolerance tests of the isolates to salt, phenol and SDS, and enzyme producing characters of amylase, proteinase and esterase were shown. Then 60 bacterial strains were chosen for 16S rRNA gene sequencing and analysis. The blasting results showed that the strains were assigned to 13 recognized genera , and the Strain 39 exhibited 96.6% similarity to Acinetobacter lwoffii(DSM2403), indicating that it might be a novel species. These results suggested that there were a lot of psychrotrophs and rich bacterial diversity in low-temperature sewage. In addition, which maybe an important and potential library of microbial resources.

OBJECTIVE: To investigate the changes of electrode impedance, THR/MCL values, and dynamic range (DR) in Combi 40+ cochlear implant after implantation. METHOD: A respective study was carried out collecting 20 consecutively implanted children's electrode impedances, THR/MCL values, and DR at seven time point during the first three years after implantation. Their variation and correlations were analyzed. RESULT: Overall, electrode impedances were lowest during the operation, and significantly rise to the highest at the first stimulation, then followed by a gradual decrease. After three months, electrode impedance of apical and medial cochlear segment were basically stable, while that of the basal segment was gradually increased. Dynamic range (DR) of apical and medial group electrode increased early after the operation and showed a stabilization from the second year, whereas that of basal group have a downward trend since the first year. However, the electric charge of each group increased significantly after three months, and then become stable after first year. Otherwise, a stronger negative rectilinear correlation was found between impedance changes with DR than with THR/MCL level. CONCLUSION The electrode impedances vary clue to different electrode position. Measuring the electrode impedance can effectively evaluate the working status of Combi C40+ cochlear implant. The dynamic range of the electrode was negatively correlated with the impedances, which made it possible to predict the width of the dynamic range by measuring the impedance 3 or 6 months after operation.
