OBJECTIVETo investigate the theoretical model of the three-dimensional structure of mosquitocidal Cry30Ca2 and its molecular docking with N-acetylgalactosamine.
METHODSThe theoretical model of Cry30Ca2 was predicted by homology modeling on the structure of the Cry4Ba. Docking studies were performed to investigate the interaction of Cry30Ca2 with N-acetylgalactosamine on the putative receptor.
RESULTSCry30Ca2 toxin is a rather compact molecule composed of three distinct domains and has approximate overall dimensions of 95 by 75 by 60Å. Domain II is a helix bundle, Domain II consists of three antiparallel β-sheets, Domain III is composed of two β-sheets that adopt a β-sandwich fold. Residue 321Ile in loop1, residues 342Gln 343Thr and 345Gln in loop2, residue 393Tyr in loop3 of Cry30Ca2 are responsible for the interactions with GalNAc via 7 hydrogen bonds, 6 of them were related to the oxygen atoms of hydroxyls of the ligand, and one to the nitrogen of the ligand.
CONCLUSIONThe 3D structure of Cry30Ca2 resembles the previously reported Cry toxin structures but shows still some distinctions. Several residues in the loops of the apex of domain II are responsible for the interactions with N-acetylgalactosamine.

Objective To provide clinical evidence for the optimal acupuncture time in acupuncture treatment of hearing disorder in kids with cerebral palsy.Method Ninety eligible patients were randomized into 3 groups, 30 in each group. Group A was treated for 30 min, group B for 45 min, and group C for 1 h. The hearing improvement was evaluated by using brain-stem auditory evoked potential (BAEP).Result The detection of BAEP showed that the latent and peak periods of wave I,Ⅲ, and V were significantly shortened in the 3 groups after intervention (P<0.01), suggesting that acupuncture can produce a marked efficacy in treating hearing disorder in cerebral palsy. The inter-group comparisons showed that the efficacy of group A was significantly higher than that of group B and C (P<0.05); there was no significant difference in comparing the efficacy between group B and C (P>0.05). It’s indicated that the optimal acupuncture time span should be 30 min.Conclusion With the same acupuncture skills, acupuncture for 30 min can produce a comparatively higher efficacy in treating infantile hearing disorder.

AIM:To investigate efficacy of ranibizumab combined with laser treatment for patients with branch retinal vein occlusion (BRVO) and macular edema.METHODS: We selected 67 patients (67 eyes) with BRVO and macular edema in our hospital from March 2013 to June 2016, they were randomly divided into observation group (n=31) and control group (n=36).The observation group was treated with ranibizumab combined with laser treatment.The control group was treated with macular grid photocoagulation.We observed best corrected visual acuity (BCVA), centre macular thickness (CMT) and macular leakage of two groups.RESULTS: The BCVA of observation group at 1, 2 and 3mo after treatment were 0.41±0.07, 0.42±0.05 and 0.48±0.05, significantly higher than those of the control group (P<0.05).The CMT of observation group at 1, 2 and 3mo after treatment were 203.11±59.13μm, 201.41±56.22μm and 204.22±60.13μm, significantly lower than those of the control group (P<0.05).The blood vessel leakage of observation group at 3mo after treatment was significantly better than that of the control group (P<0.05).No leakage ratio in the observation group was 71%.There were no postoperative infection, aseptic endophthalmitis and other complications in the two groups.CONCLUSION: Ranibizumab combined with laser treatment in patients with BRVO and macular edema has better curative effect, can improve the visual acuity of patients, eliminate macular edema, and is safe and reliable.

Objective To investigate the aetiology of acute exacerbations of COPD (AECOPD),and the effects of moxifloxacin in the treatment of AECOPD.Methods Patients with stable COPD based on GOLD criteria were included in the study.Sputum collected at first exacerbation was analyzed for bacteria count and culture.IL-6,IL-8 and TNF-?were measured by enzyme- linked immunosorbent assay (ELISA).Eligible patients were randomized to receive moxifloxacin (400 mg qd for 5 days) or ce- faclor (250 mg q8h for 7 days).Efficacy parameters were evaluated at 7 and 14 days after treatment initiation and 1 year later. Results Of the 46 patients with moderate or severe COPD (male 38,moderate 24),21 (45.65%) were microbiologically evalu- able at baseline.The main pathogen was Haemophilus influenzae (10/21).Clinical efficacy rate was 87.0% in moxifloxacin group and 82.6% in cefaclor group.Bacterial eradication rate was 80.0% and 72.7% respectively.The difference between groups was not statistically significant in terms of clinical or microbiological efficacy.In moxifloxacin arm,the frequency of ex- acerbation was 2.6?1.0,significantly lower than control arm (3.5?1.4,P

Aim To explore the effect of prenatal expo-sure to lipopolysaccharide ( LPS ) on lipid metabolism in mice offspring from the starting point of FAT/CD36 expression.Methods 8-week old C57 mice mated 2∶1, then they were caged separately , marked as preg-nancy 0 d.The pregnant mice were given single intrap-eritoneal injection of 75 μg? kg -1 LPS, and the con-trol received injections of 0.2 mL saline .The perirenal adipose of female mice and epididymis adipose of male mice were collected in 4 w,8 w,12 w,respectively. The weight of visceral adipose tissue and the free fatty acid( FFA) and triglyceride ( TG) of adipose tissue and FAT/CD36 of offspring mice were quantitated .Results The body weight of offspring of LPS group was also significantly higher than that of NS group , and LPS group offspring displayed increased adipose tissue wet weights , the expression of TG and FFA was increased in LPS group compared with NS .Especially , prenatal exposure to inflammatory stimulation resulted in marked increase of FAT/CD36 and abnormal adipocyte development .Conclusions Inflammation induced by prenatal exposure to LPS results in increased body weight , adipose coefficient and FAT/CD36 that might develop into obesity in adult mice .These results are relevant in that anomalous local adipose tissue and FAT/CD36 regulation may be an important mechanism underlying obesity .
