Objective To summarize the diagnosis and treatment experience of adenine phosphoribosyltransferase deficiency after kidney transplantation. Methods Clinical data of 1 patient with adenine phosphoribosyltransferase deficiency after kidney transplantation were retrospectively analyzed. Clinical characteristics, diagnosis, treatment and prognosis of adenine phosphoribosyltransferase deficiency were summarized by literature review. Results Renal biopsy showed that salt crystallization was found in most renal tubule lumen and positive results were observed under polarized light microscopy. After allopurinol, hemodialysis and anti-crystallization treatment, the graft function was gradually recovered. After postoperative 1-year follow-up, the patient's renal function was properly recovered. Conclusions Adenine phosphoribosyltransferase deficiency after kidney transplantation may lead to delayed graft function or graft dysfunction. Early detection, diagnosis and treatment may delay disease progression and improve renal function.

OBJECTIVE To establish the HPLC fingerprint of Jianpi huayu decoction, and to determine the contents of 8 components. METHODS Thermo Hypersil Gold C18 column was used with mobile phase consisted of methanol-0.05% phosphoric acid aqueous solution (gradient elution) at the flow rate of 1.0 mL/min. The column temperature was 30 ℃, the injection volume was 5 μL. The detection wavelength of matrine was 211 nm, and the other components’ detection wavelength was 283 nm. The similarity evaluation of HPLC fingerprints for 10 batches of Jianpi huayu decoction was performed by using the Similarity Evaluation System of Chromatographic Fingerprint of Traditional Chinese Medicine (2012 edition). The contents of chlorogenic acid, vanillic acid, p-coumaric acid, ferulic acid, hesperidin, quercetin, bergapten and matrine in the samples were determined by HPLC. RESULTS HPLC fingerprint of Jianpi huayu decoction was established. A total of 27 common peaks were identified, and 8 components were identified. The similarity between 10 batches of samples and the control map ranged from 0.942-0.999. RSDs of precision, repeatability and stability tests were less than 3% (n=6). The average recoveries of chlorogenic acid, vanillic acid, p-coumaric acid, ferulic acid, hesperidin, quercetin, bergapten and matrine were 99.48%, 101.32%, 101.18%, 100.79%, 101.12%, 99.19%, 99.81% and 102.46%, respectively; RSDs were 1.34%, 0.93%, 1.90%, 1.84%, 0.54%, 1.53%, 1.33% and 1.01%, respectively (n=6). The contents were 0.021-0.061, 0.025-0.034, 0.116-0.295, 0.006- 0.062, 0.014-0.053, 0.017-0.026, 0.014-0.027 and 14.05-24.11 mg/g, respectively. CONCLUSIONS The established fingerprint and content determination method can provide a reference for the quality control and subsequent preparation development for Jianpi huayu decoction.

Plant diterpenoids are widely distributed and abundant natural products with diverse structures and functions in nature, which have been commonly used in pharmaceutical, agricultural and industrial production. In recent years, plant diterpenoids have attracted increasing attention, including their biosynthetic pathways, transcriptional regulatory networks, and biological functions. Herein, the biosynthetic pathways of diterpenoids are summarized in a modular fashion. Further, the regulatory network between diterpene biosynthesis and environmental factors is reviewed. Insights into diterpene metabolism may drive elucidation of complex active diterpene pathways and serve as a knowledge repository for metabolic engineering and cell factory construction.

Objective To investigate clinical effect of local decompression and selective interbody fusion with pedicle screw fixation technique for the treatment of degenerative lumbar scoliosis. Methods Medical records of 122 degenerative lumbar scoliosis patients were retrospectively studied. All cases were treated by selective interbody fusion,local decompression and pedicle screw fixation. Group A(L5 fusion)and group B(S1 fusion)un?derwent imaging analysis,and Suk criteria was used to evaluate the fixation,decompression,bone graft fusion. JOA scores were used to evaluate curative effect of excellent and good rate. Results There were no significant difference in operating time,blood loss and postoperative drainage volume between two groups. Follow?up period for all patients is(16.2 ± 0.8)months. X?ray revealed that Cobb′s angle on the coronal plane,the correction rate of lor?dosis and sagittal Cobb′s angle after treatment,the correction rate of lordosis in group B were better than in group A (P<0.05). There were no significant differences in intervertebral fusion rate,low back pain score of JOA and the effective rate at final follow?up between two groups(P>0.05). There was no infection or screw breakage and pulling out. The incidence rate of adjacent vertebral body disease in group A was higher than that in group B(P < 0.05). Conclusions Local decompression and selective interbody fusion with pedicle screw fixation technique for the treat?ment of degenerative lumbar scoliosis can produce satisfactory short to mid?term clinical curative effect.

OBJECTIVETo explore the effect of lentivirus-mediated shRNA interference of Cx26 on epithelial-mesenchymal transition (EMT) and invasion of highly invasive human hepatocellular carcinoma cells in vitro.
METHODSSK-Hep-1 cells were infected with the lentivirus for delivering Cx26 shRNA, and the stably transfected cells were selected by puromycin. The interference efficiency of shRNA-Cx26 was assessed with real-time PCR and Western blotting. The morphological changes of the transfected SK-Hep-1 cells were observed microscopically, and the protein expressions of E-cadherin and vimentin were detected using Western blotting. The effect of Cx26 interference on the invasiveness of SK-Hep-1 cells was determined by Transwell invasion assay.
RESULTSCompared with SK-Hep-1 cells infected with empty EGFP vector and uninfected cells, the cells transfected with shRNA-Cx26 showed significantly reduced mRNA and protein expressions of Cx26 (P<0.01), which resulted in obvious morphological conversion from mesenchymal cells to epithelial cells. shRNA-Cx26-transfected cells showed significantly increased E-cadherin protein expression (P<0.01) but decreased vimentin expression (P<0.01) with obviously attenuated invasive ability in vitro (P<0.01).
CONCLUSIONTargeted down-regulation of Cx26 expression can inhibit the EMT and invasion of SK-Hep-1 cells in vitro.
