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 observe the delayed brain myelination of children with phenylketonuria(PKU)combined with epilepsia,and explore effectiveness of the treatment and provide an objective criteria for patient recovering evaluation.Methods There were 42 PKU patients,aged 3 to 72 months were selected.The concentration of phenylalanine tested by high pressure liquid chromatography was greater than 1.2 mmol/L in blood,diagnosed as PKU.According to electroencephalogram and clinical symptom,21 cases were diagnosed as epilepsy,the other 21 cases were used as control group.All patients were taken MRI before treatment.Myelination in 10 sections(cerebellum,pons,mesencephalon,internal capsule posterior limb,corpus callosum,internal capsule anterior limb,occipital lobe,parietal lobe,temporal lobe,frontal lobe)were evaluated.Results Delayed myelinations were located mainly in the cerebral lobes and corpus callosum,average delayed incidence of the 10 region was 44.8% in epilepsy group and 30.9% in control group.The incidence of the corpus callsum was 80.9% in epilepsy group,52.4% in control group,the number of sections of delayed myelination showed statistically significant between 2 groups(P

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.

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

Objective To measure the expression of activin receptor-like kinases 1(ALK1)in dermal fibroblasts from patients with systemic scleroderma(SSc)and to estimate its role in the production of fibronectin and plasminogen activator inhibitor-1(PAI-1).Methods Dermal fibroblasts were isolated from the lesions of 12 patients with SSc as well as the normal skin of 14 healthy controls,and subjected to a primary culture.The third-passage fibroblasts were used in the next experiment.Western blot and indirect immunofluorescence technique were utilized to quantify the expression of ALK1.A specific siRNA targeting ALK1 was designed,constructed,and transiently transfected into the control dermal fibroblasts,which were then classified into 2 groups to be cultured with or without the presence of transforming growth factor(TGF)-β1 for 72 hours followed by the detection of fibronectin and PAI-1 expression with Western blot.Results As Western blot and direct immunofluorescence technique showed,both control and SSc fibroblasts showed an expression of ALK1 in the cytoplasm and membrane,and the expression intensity of ALK1 in SSc fibroblasts was significantly higher than that in the control fibroblasts(1.97 ± 0.05 vs.1.12 ± 0.03,t =50.96,P ＜ 0.05).The expression of ALK1,fibronectin and PAI-1 was decreased by 90％,58％ and 31％ respectively in specific siRNA-transfected SSc fibroblasts compared with the control siRNA-transfected fibroblasts.TGFβ1 significantly increased the expression of ALK1,fibronectin and PAI-1 in the control siRNA-transfected fibroblasts,but the increase was markedly inhibited by the siRNA-targeting ALK1.Conlusion TGFβ1 can promote the production of fibronectin and PAI-1 via ALK1 in fibroblasts,and ALK1 may be involved in the development of sclerosis in SSc.

BACKGROUND:Prefabricated customized bone flaps have the advantages of few trauma, good vascularization, ossification with predetermined shape, and can be used to restore bone defects with compromised blood bed.
OBJECTIVE:To establish animal models of mandibular reconstruction with prefabricated, customized bone flaps.
METHODS:After computed tomography scanning of nine rhesus’ head, customized meshes were made. After loading with recombinant human bone morphogenetic protein-2-incorporated demineralized freeze-dried bone al ograft (DFDBA) or coral ine hydroxyapatite (CHA), the constructs were implanted in latissimus dorsi muscle. Meanwhile, segmental mandibular defects were created, and the customized meshes loaded with DFDBA, CHA, or recombinant human bone morphogenetic protein-2-incooperated DFDBA and CHA were implanted in situ. At 13 weeks, prefabricated bone flaps with recombinant human bone morphogenetic protein-2-incorporated DFDBA or CHA were transferred to repair segmental mandibular defects. Clinical and histological analyses were used to evaluate the ossification and vascularization of the prefabricated implants in ectopic and orthotopic sites.
RESULTS AND CONCLUSION:Segmental mandibular defects were successful y restored with prefabricated bone flaps and recombinant human bone morphogenetic protein-2-incorporated CHA in situ, but other segmental mandibular defects remained with recombinant human bone morphogenetic protein-2-incorporated DFDBA, DFDBA and CHA in situ. Moreover, mandibles reconstructed with prefabricated bone flaps revealed more regenerated and homogeneous bone formation than other reconstructions. These findings suggest that the animal model of mandibular reconstruction with prefabricated, customized bone in rhesus monkey is applicable.

Background: Acute mastitis is an acute infectious disease of breast. Antibiotic treatment is often unable to obtain a good effect, and we should actively look for a safe and effective non-drug therapy. Objective: To validate the clinical efficacy of kneading and dispersing manipulation in treatment of early-stage acute mastitis. Design, setting, participants and interventions: According to the multicenter randomized controlled trial design, 198 cases of acute mastitis from Yueyang Hospital of Integrated Traditional Chinese Medicine, Longhua Hospital, and Shanghai Yangpu Maternity and Child Health Hospital were randomly divided into treatment group and control group. There were 99 cases in each group. Patients in the treatment group were only treated with manipulation, and cefradine was orally administered to patients in the control group. Main outcome measures: The local breast lump size, clinical symptoms and the adverse reactions in the two groups were observed before and after the treatment. Results: The total response rates in the treatment and control group were 95.92% (94/98) and 80% (76/95) respectively. There was a significant difference in the total response rate between the two groups (P<0.05). There were significant differences in the score of breast lump size, and the score of signs and symptoms between the two groups (P<0.05). Conclusion: Kneading and dispersing manipulation has certain effects on early-stage acute mastitis, and the therapy is safe and repeatable.
