BACKGROUND: Cecropins are a kind of micromolecule protein with antibacterial activity. Eukaryotic cell-expressed or artificially synthesized Cecropins is characterized by low efficiency and high cost. OBJECTIVE: To clone and express an antibacterial peptide gene of Musca domestica Cecropin A, and to identify recombinant expression product. METHODS: Mature Musca domestica Cecropin A encoding nucleotide sequence was searched from the GenBank and amplified by RT-PCR. The gene of Musca domestica Cecropin A was cloned into prokaryotic expression vector pET32a and fused with gene of Thioredoxin (Trx) and expressed in E.coli BL2l (DE3). After induction by isopropyl-β-D-thiogalactoside, the sera of the immunized rabbits were collected after rabbits were immunized with the hemolymph of housefly larvae. Recombinant protein was identified by western blot analysis and N-[Tris(hydroxymethyl)methyl]glycine-sodium dodecylsulfate-polyacrylamide gel electrophoresis.RESULTS AND CONCLUSION: After induction by isopropyl-β-D-thiogalactoside, E.coli BL21 expressed mature Cecropin. Rabbit anti- housefly larvae sera, N-[Tris(hydroxymethyl)methyl]glycine-sodium dodecylsulfate-polyacrylamide gel electrophoresis and western blot analysis results confirmed that expression products were mature Cecropin. These suggest that prokaryotic expression system can be utilized to obtain natural mature Cecropin.

MicroRNA (miRNA) regulate the expression of target mRNA according to the specific base pairing. They are involved in proliferation,differentiation and apoptosis of cells. The expression of miRNA has distinct differences between normal tissues and cancers, miRNA can be oncogenes but also suppressor genes, they play an important role in cancer. And miRNA are promising to be a new therapeutic target. In this review, we will discuss the advance in the research of miRNA in cancer.

BACKGROUND: Fiber posts are currently perceived as promising alternatives to cast metal posts, as their elastic modulus are similar to that of dentin, producing a favorable stress distribution and providing more esthetic outcomes for endodontically treated teeth. Failure of a fiber post and composite resin core often occurs at the junction between the two materials. This failure process requires better characterization.OBJECTIVE: To compare the bond strength of fiber posts after three surface treatments to a composite resin. METHODS: The coronal portions of 20 mandibular premolars with a single root canal were removed and were endodontically treated. After post space preparation, the roots were divided into four groups and the fiber posts and resin cores were lured. In the three testing groups, the surfaces of fiber posts were silaned, sandblasted or etched with hydrogen peroxide. In the control group, the surfaces of fiber posts were not treated. All specimens were exposed to cyclic loadings and thermal cycles. The roots were sectioned into slices with 1 mm thickness and their bond strengths were tested with a universal material testing machine. Test piece following testing was placed under optical microscope to observe the breakage method.RESULTS AND CONCLUSION: Stickiness strength was significantly greater in the sandblasted and hydrogen peroxide groups compared with the control group (P < 0.05). No significant difference in stickiness strength was determined between the sandblasted and hydrogen peroxide groups (P > 0.05). No significant difference in stickiness strength was detected between the silaned and control groups (P > 0.05). The splicing destruction among each group was the main breakage method between materials and fiber posts. The surface treatment of fiber posts with sandblast or hydrogen peroxide significantly enhanced the bond strength of the composite resin tested. The surface treatment of fiber posts with silane did not enhance the bond strength of the composite resin.

Atrial fibrillation is the most common arrhythmia in clinical practice.However,the therapeutic effects of traditional antiarrhythmic medicines are far from satisfactory,because of the high rate of arrhythmia recurrence and the potential proarrhythmia effect.Recently,with the further investigation of the mechanisms that initiate and perpetuate atrial fibrillation,and the support of extensive data from clinical trials and animal experiments,thera-peutics based on anti-inflammation,antioxidation,regulation on renin-angiotensin-aldosterone system(RAAS)and gap junction may be new therapeutic targets for the treatment of arrhythmia.In this paper,the potential molecular mechanisms involved in these processes and several clinical trials about some non-traditional antiarrhythmic medi-cines were reviewed,in order to propose a new idea about the development of antiarrhythmic medicines.

Objective To observe the clinical efficacy of tongue acupuncture plus balloon dilatation in treating deglutition disorders due to achalasia of the cricopharyngeus muscle after cerebral stroke.Method Forty-eight patients with deglutition disorders due to achalasia of the cricopharyngeus muscle after cerebral stroke were randomized into a treatment group and a control group, 24 cases each. The two groups both received conventional rehabilitation training. In addition, the treatment group was given tongue acupuncture plus balloon dilatation, and the control group was by balloon dilatation alone. The two groups were treated once a day, for a total of 4 weeks. The water drinking test score and Standardized Swallowing Assessment (SSA) were evaluated before and after the treatment.Result The water drinking test and SSA scores were significantly changed after the intervention in both groups (P<0.05). After the treatment, the water drinking test and SSA scores in the treatment group were significantly different from those in the control group (P<0.05).Conclusion Tongue needling plus balloon dilatation is an effective approach in treating deglutition disorders due to achalasia of the cricopharyngeus muscle after cerebral stroke.

ObjectiveTo investigate the clinicalefficacy of warm needling plus Chinese herb fumigation in treating plantar fasciitis.MethodSixty-one patients with plantar fasciitis were randomly allocated to a treatment group of 31 cases and a control group of 30 cases. The treatment group receivedwarm needling plus Chinese herb fumigation and the control group, warm needling alone.ResultThe total efficacy rate and the cure rate were 100.0% and 61.3%, respectively, in the treatment group and 96.7%and 40.0%, respectively, in the control group. There was no statistically significant difference in the total efficacy rate between the two groups (P>0.05), but the cure rate was significantly higher in the treatment group than in the control group and there was a statistically significant difference between the two groups (P<0.05). There was a statistically significant pre-/post-treatment difference in the VAS score in the two groups (P<0.01), indicating that both the groups had a good analgesic effect. There was a statistically significant post-treatment difference in the VAS score between the treatment and control groups (P<0.01), indicating that theanalgesic effect was better in the treatment group than in the control group.ConclusionThe efficacy of warm needling plus Chinese herb fumigation is better than that of warm needling alone in treating plantar fasciitis.

Lung cancer is the most common cancer worldwide, accounting for approximately 18%of all cancer-related deaths. Circulating tumor cells (CTCs) have the capacity to spread into the blood stream. This capacity of CTCs is one of the most critical fac-tors for unfavorable clinical outcome of patients with NSCLC. Detection of CTCs using a simple blood test may assist in early detec-tion of lung cancer. Researchers have attempted to isolate CTCs from peripheral blood using various techniques. Although reports on CTC detection are abundant, methodological aspects concerning sensitivity, specificity, and reproducibility have prevented a clear ap-praisal of the clinical impact. This paper gives a brief description of each CTC detection method.

Objective To investigate the clinical features,diagnosis and treatment of dementia with Lewy bodies(DLB).Methods A clinical, neuropsychological ,neuroimaging and therapeutic analysis on 8 cases of clinically diagnosed dementia with Lewy bodies was conducted.Results Fluctuating cognition(FC) was the first symptom in all 8 patients,followed by persistent visual hallucinations and Parkinsonism. Patients showed moderate dementia and severe constructional disabilities .The ratings of FC were mild to moderate with scores 4-10(mean 7.4?2.1). The UPDRS scores ranged from 31 to 71 (mean 47.8?14.3). The polysomnography of the patient with REM sleep behavior disorder showed augmented submental muscle activity during REM and no EEG epileptiform activity. MRI or CT scans showed global brain atrophy in all 8 patients. SPECT of Sleep patient showed impaired striatal dopaminergic function . L-dopa and donepezil therapy were effective.Conclusions The main clinical features of DLB are fluctuating cognition, persistent visual hallucinations and extrapyramidal motor symptoms. The diagnosis relies on history and current symptoms, neuropsychological testing and findings of neuroimaging. L-dopa and cholinesterase-inhibitor drugs can improve mobility and cognitive symptoms in DLB.
