The study aimed to clone the open reading frame of cinnamate 4-hydroxylase (C4H) from Aquilaria sinensis and analyze the bioinformatics and expression of the gene. One unique sequence containing C4H domain was discovered in our previous reported wound transcriptome dataset of A. sinensis. The open reading frame of C4H was cloned by RT-PCR strategy with the template of mixed RNA extracted from A. sinensis stem which treated by different wound time. The bioinformatic analysis of this gene and its corresponding protein was performed. C4H expression profiles in responds to MeJA (methyl jasmonate) application were analyzed by real-time PCR. The length of C4H open reading frame (ORF) was 1 515 bp, encoding 514 amino acids. The GenBank accession number is KF134783. Inducible-experiments showed that the genes were induced by mechanical wound as well as MeJA induction, and reached the highest expression level at 8 h and 20 h, respectively. The full-length cDNA of C4H and its expression patterns will provide a foundation for further research on its function in the molecular mechanisms of aromatic compounds and flavonoids biosynthesis.

Objective To analyze C4d deposition in the patients with late acute renal allograft rejection,and explore the role of C4d in grafts survival and grafts loss. Methods Thirty-six patients clinical and pathologically diagnosed as having acute rejection more than one year post-transplant were selected. C4d was detected by immunohistochemistry in renal allograft biopsies. The effect of C4d deposition on long-term graft survival was studied. Results Among 36 recipients with late acute renal allograft rejection, 16 cases were positive for C4d (44.4 %) and 20 negative for C4d (55.6 %). Five cases experienced graft loss in C4d positive group (31.3 %), while 6 cases in C4d negative group (30.0%). There was no significant difference in the graft loss rate between C4d-positive group and C4d-negative group. Log-Rank test demonstrated there was no significant difference in graft survival between C4d-positive group and C4d-negative group. The count of the interstitial infiltrated eosinophils in renal allograft was (9.4 + 4.5) and (2.6 + 1.8) respectively in the C4d-positive group and C4dnegative group (P<0.05). Conclusion C4d deposition in peritubular capillary of the recipients with late acute renal allograft rejection might not be a prognostic marker for graft outcome.

Objective:To observe the clinical efficacy of Governor Vessel-unblocking and brain-refreshing scalp acupuncture for cerebral palsy (CP) complicated with intellectual disabilities. Methods:A total of 300 CP cases aged between 1 and 5 years were randomly allocated into a treatment group (n=150) and a control group (n=150). Patients in the treatment group were treated with Governor Vessel-unblocking and brain- refreshing scalp acupuncture combined with rehabilitation training, whereas patients in the control group received rehabilitation training alone. The Beijing Gesell developmental (Gesell) scale and gross motor function measure (GMFM) scale were used to assess the motor and intellectual development before and 3 months after the treatment. In addition, the head CT/MRI examination was applied to assess the brain nerve repair before and after the treatment. Results:After the treatment, the total effective rate in the treatment group was 78.0%, versus 42.7% in the control group, showing a statistical significance (P<0.05). As for scores of five subscales in the Gesell scale, there were significant intra-group differences in the treatment group (allP<0.05); and the scores in the treatment group were significantly better than those in the control group (allP<0.05). As for scores of five dimensions in GMFM scale, there were significant intra-group differences in the treatment group (allP<0.05); and the scores in the treatment group were significantly better than those in the control group (allP<0.05). According to the head CT/MRI findings, the total effective rate was 73.3% in the treatment group, versus 62.0% in the control group, showing a statistical significance (P<0.05). Conclusion:When used in combination with rehabilitative training, Governor Vessel-unblocking and brain-refreshing scalp acupuncture can significantly improve the clinical efficacy for cerebral palsy complicated with intellectual disabilities. It can also improve the patients' motor function, intelligence and language ability.
