In this study, a composite cell model for evaluation of idiosyncratic drug-induced liver injury (IDILI) was established in vitro from the perspective of immune inflammation. And this model was used to evaluate the risk of IDILI for 2,3,5,4'-tetrahydroxy-cis-stilbene-2-O-β-glucoside (Cis-SG) and 2,3,5,4'-tetrahydroxy-trans-stilbene-2-O-β-glucoside (Trans-SG). To determine the low, medium, and high dosage of Cis-SG and Trans-SG, CellTiter-Glo^® 3D Cell Viability Assay was used to detect the effects of Cis-SG and Trans-SG on cell viability of HepG2 cells in three dimensional (3D) culture, and MTT assay was used to detect the effects of Cis-SG and Trans-SG on cell viability of THP-1 derived macrophages. THP-1 derived macrophages were incubated by Cis-SG and Trans-SG directly or supernatants from HepG2 cells incubated with them. Enzyme linked immunosorbent assay (ELISA) was used to detect the levels of interleukin-1β (IL-1β) in the supernatants of the THP-1 derived macrophages. Western blot and reverse transcription-polymerase chain reaction (RT-PCR) were used to determine the expression of apoptosis-associated speck-like protein (ASC), Nod-like receptor protein 3 (NLRP3), cysteinyl aspartate specific proteinase-1 (caspase-1), and IL-1β in THP-1 derived macrophages. The results showed that there was no effect on the secretion of IL-1β in THP-1 derived macrophages incubated by Cis-SG and Trans-SG directly. However, the secretion of IL-1β, the protein and mRNA expression of ASC, NLRP3, caspase-1, and IL-1β significantly increased in THP-1 derived macrophages incubated by supernatants from HepG2 cells incubated with 1, 5, and 25 μmol·L^-1 Cis-SG or 25 μmol·L^-1 Trans-SG. In summary, the composite cell model for evaluation of IDILI established in vitro has been successfully applied in testing Cis-SG and Trans-SG. This composite cell model is helpful to evaluate and screen drugs with IDILI risk in vitro preliminarily, which provides methods for predicting and solving the idiosyncratic liver toxicity of drugs.

AIM: To evaluate the safety, efficacy and stability of posterior chamber phakic intraocular lens ( ICL ) implanation and clear lens extraction for the correction of high myopia.
METHODS: The study enrolled 56 cases ( 100 eyes ) of high myopia. Group I comprised 32 cases ( 58 eyes ) receiving ICL implantation and Group II comprised 24 cases (42 eyes) undergoing clear lens extraction. In this study, we evaluated the two groups of subject's the visual and refractive results, intraocular pressure ( IOP ) , endothelial cell density ( ECD ) , anterior chamber depth ( ACD) , lens transparency, the surgical complications as well as visual adverse symptoms before and after surgery.
RESULTS: The postoperative subjects in group I and group II were followed, uncorrected vision acuity ( UCVA)>0. 5 were 69. 0% in group I and 71. 4% in group II after 3mo. UCVA>0. 5 were 72. 4% in group I and 73. 8% in group II after 1a. Predictability of the manifest spherical equivalent refraction within±1. 00D was achieved in 62. 1%of eyes in group I and 57. 1% in group II after 1a. The central vault of the ICL ( distance from posterior surface of ICL to the crystalline lens ) measured with anterior segment optical coherence tomography ( AS-OCT ) was 0. 35-0. 54 (0. 40±0. 16) mm. Twelve point one percent of eyes in group I and 7. 1% of eyes in group II had transient mild increase in IOP. Here were statistically significant differences between preoperative and postoperative ECD (P<0. 001 ). Complications of surgery: 1 eye had ICL spontaneous rotation, 2 eyes had anterior subcapsular cataract, 4 eyes noticed halos around lights at night in group I. Three eyes had posterior capsule mild opacification, 3 eyes noticed halos around lights at night, 12 eyes had difficulty in near vision in group II.
CONCLUSION: ICL implantation and clear lens extraction are effective, safe and predictable surgical option for the management of high myopia. No severe complications occurred, but its long time effect and safety still need more time to prove.

OBJECTIVETo explore the effect of electro-acupuncture to improve the bladder function after acute spinal cord injury in rats and its possible mechanism.

METHODSSixty healthy adult male SD rats of SPF grade, with body weight of 220 to 250 g, one week after feeding adaptation, were randomly divided into sham operation group, model group, electro-acupuncture group, electro-acupuncture control group with 15 rats in each group. Sham operation group underwent no stimulation, and the moderate damage model of spinal cord injury were made in other three groups according to modified Allens method. The model group were not treated, electro-acupuncture group were treated with electro-acupuncture on Zhibianxue and Shuidaoxue, and electro-acupuncture control group were treated with electro-acupuncture on 0.5 inch next to Zhibianxue and Shuidaoxue. The frequency of 2/100 Hz, current of 1 mA, stimulation time of 15 min, once a day, left and right alternately stimulate every time, for a total of 7 times. The changes of residual urine volume and urine output in rats at the 1st and the 7th days after operation were observed. And 7 d later, the rats were sacrificed and the injured spinal cord were taken out to observe the apoptosis, and to detect the changes of Bcl-2, Bax, Bad content.

RESULTSAfter modeling,the rats of three groups showed different bladder dysfunction. In electro-acupuncture group and electro-acupuncture control group, the residual urine volume of the 7th day after operation was significant lower than the 1st day after operation (P < 0.001), and there was statistically significant difference on the 7th day after operation between two groups (P < 0.001). Compared with model group, the urine output of electro-acupuncture group and electro-acupuncture control group was significantly increased on the 7th day after operation, and there was sig- nificant difference between electro-acupuncture group and electro-acupuncture control group (P < 0.001). Electro-acupuncture can inhibit apoptosis of spinal cord neurons by TUNEL detection. Postoperative at 7 d, the rate of nerve cell apoptosis in electro -acupuncture group and electro-acupuncture control group was significant increased than model group (P < 0.01, P < 0.05), and there was significant difference between electro-acupuncture group and electro-acupuncture control group (P < 0.005). Compared with model group, the positive expression rate of Bax, Bad decreased (P < 0.01, P < 0.05), and Bcl-2 increased (P < 0.01) in electro-acupuncture group and electro-acupuncture control group,there was significant difference between electro-acupuncture group and electro-acupuncture control group (P < 0.01).

CONCLUSIONElectro-acupuncture can obviously promote the repair of acute spinal cord injury,its mechanism may be through increasing Bcl-2, inhibiting the expression of Bax, Bad, which inhibits the apoptosis of spinal cord neurons.

Objective To construct PPAR?and PPAR?response element (PPRE)-controlled luciferase expression vectors,and to determine whether the traditional Chinese medicine emodin activates PPAR?and improves the glucose uptake by HepG2 hepatocytes.Methods (1) PPAR?and PPRE luciferase expression vectors were constructed and were applied to screen more than 20 ingredients of the traditional Chinese medicine. (2) HepG2 cells were incubated with emodin which can activate PPAR?and PPRE luciferase activity,and the PPAR?mRNA expression level was evaluated by RT-PCR/Southern blot.(3) PPAR?and glucose transporter 2 (Glut2) proteins were determined by Western blot analysis in HepG2 cells treated with emodin.(4) The glucose uptake rate was measured using 2-deoxy-[~3H]-D-glucose in HepG2 cells after treatment with emodin.Results (1) Emodin stimulated luciferase activity controlled by PPRE in dose-dependent manner at concentrations of 0.04 to 180?mol/L in COS-7 cells.The highest value was about 4 folds of control in the cells treated with 90?mol/L emodin (P

In order to confirm the role that the 49th amino acid residue plays in enzymatic inactivity of Glutamine 49 phospholipase A2(Gln49-PLA2),site-directed mutagenesis of its 49th amino acid gene codon was conducted using PCR.Aspartic acid 49 phospholipase A2(Asp49-PLA2-Q49D-PLA2),the mutant of Gln49-PLA2 was expressed in E.coli with pET32a+ vector.The fusion protein,expressed as inclusion body,after being denatured,was on-column refolded and purified by immobilized metal affinity chromatography(IMAC),and then cleaved by Factor Xa.The mature Q49D-PLA2 mutant was obtained by Hitrap SP cation exchange and Superdex 75 gel filtration chromatography,with the recovery rate of 1.3%,and the specific activity of the mature Q49D-PLA2 mutant was 72 U/mg.It has been demonstrated that the 49th glutamine amino acid residue is the main reason in enzymatic inactivity of Gln49-PLA2 and the results are helpful for denatured protein refolding,especially in rich disulfide bonds conditions.

Objective: To discuss the application principle in tuina manipulation for lumbar intervertebral disc herniation (LIDH) in Chinese literatures published in recent 30 years. Methods: The three major Chinese databases, Wanfang Academic Journal Full-text Database (Wanfang), Chongqing VIP Database (CQVIP) and China National Knowledge Infrastructure (CNKI), were searched to collect the studies of tuina manipulations in treatment of LIDH published in recent 30 years. Clustering analysis was applied to analyze the top 20 tuina manipulations for LIDH. Results: The top 20 most frequently used manipulations for LIDH were Gun-rolling, Rou-kneading, Dian-digital pressing, oblique Ban-pulling, An-pressing, Tanbo-plucking, Bashen-pulling and extending, horizontal Tui-pushing, Na-grasping, Anrou-pressing and kneading, Dou-shaking, Yao-rocking, Ca-scrubbing, Pai-patting, post-extension Ban-pulling, Mo-rubbing, Zhen-vibrating, Nie-pinching, fist-back Ji-tapping, and dorsal Shen-extending methods. The involved manipulations can be divided into two categories by the treated body areas. One category is applied to the soft tissues, including Gun-rolling, Rou-kneading, Dian-digital pressing, An-pressing, Tanbo-plucking, horizontal Tui-pushing, Na-grasping, Anrou-pressing and kneading, Ca-scrubbing, Pai-patting, Mo-rubbing, Zhen-vibrating, Nie-pinching, and fist-back Ji-tapping methods. The other category is applied to bones and joints, including oblique Ban-pulling, Bashen-pulling and extending, Dou-shaking, Yao-rocking, post-extension Ban-pulling, and dorsal Shen-extending methods. Conclusion: Based on the treated body area, the tuina manipulations applied to treat LIDH are predominated by the ones performed on soft tissues, assisted by those on bones and joints. From the way of force exertion, the involved manipulations are majorly the swinging methods, followed by squeezing and pressing ones. The manipulations applied to bones and joints are predominated by the Ban-pulling ones, followed by the Bashen-pulling and extending ones.

Severe root rot was observed in fields of cabbages (Brassica oleracea L.) in 2015 in China. Cardinal symptoms of this disease included root rot and wilting leaves. A fungus was isolated from diseased tissues consistently. Based on the morphological features and molecular analysis of the ITS-5.8S rDNA and D1/D2 domain of the 28S rRNA gene, it was identified as Plectosphaerella cucumerina. This is the first report of P. cucumerina causing cabbage root rot in China and the world.
