AIM: To observe the effects of H_2O_2 on apoptosis of skeletal muscle satellite cells (SMSC)and mitochondrial membrane potential (MMP), and protective effect of erythropoietin(EPO). METHODS: SMSC in vitro were divided into three groups: H_2O_2 group, H_2O_2+EPO group and control. Apoptosis rate and the means were obverted by monofluorescence flow cytometry. The morphological change of apoptosis cells were observed under fluorescence microscopy after Hoechst 33258 staining. RESULTS: The cells in H_2O_2 group show the highest apoptosis rate (22.13±1.79)%. In H_2O_2+EPO group, apoptosis rate were (16.47±2.53)%, (4.97±0.55)% and (2.93±0.47)% according to the EPO treated levels (10, 20 or 40 kU/L), respectively. MMP level in H_2O_2 group was the lowest 9.70±0.09. MMP levels in H_2O_2+EPO group were 12.67±0.32, 27.90±0.66, 44.53±0.93, respectively according to the EPO treated levels (10, 20 or 40 kU/L). In control group, apoptosis rate was 1.93±0.57 and MMP was 51.37±0.64. In H_2O_2 group and H_2O_2+ low dosage EPO group, Hoechst 33258 staining showed obvious apoptosis. CONCLUSION: EPO inhibits the apoptosis induced by H_2O_2 and stabilizes the MMP, which is related to the dosage of EPO.

Nanobodies are derived from the variable domain of the heavy-chain antibodies (HCAbs) that occur naturally in the serum of Camelidae. They are the smallest antibody fragments capable to bind antigens. With the characteristics of their increased solubility, increased domain stabilities, nanomolar affinities, easy crossing the blood-brain barrier, easy generation, engineering, optimization and tailoring, easy humanization, nanobodies have extensive application prospects in diagnosis and detection. Although nanobody has demonstrated tremendous success, a number of practical challenges limit its broader applications in disease diagnosis and detection, including construction of a phage library and selection of nanobody fragments with high affinity and immunogold labeling technique. Here, we review several recent findings on the use of nanobodies in molecular diagnostics and suggest some practical strategies in resolving the current challenges in this attractive research area, particularly to optimize the affinity, solubility, humanization of nanobodies.

Objective To observe the degeneration of Brugia malayi in Meriones unguiculatus model. Methods Microfilaria of Brugia malayi derived from Meriones unguiculatus was used to infect Anopheles sinensis . Infective stage larvae (L 3) from mosquito vector were collected and inoculated into abdomen of Meriones unguiculatus. Successive 33 generations of the parasite in the rodent model have been observed. Results Since 1974 when the animal model was established, the parasite has lasted for 33 generations, the positive rate of Meriones unguiculatus with microfilaria gradually reduced from 80% of the 28th generation to 16% of the 32nd generation and finally to 0 at the 33rd generation. Conclusion It became difficult for the larvae of Brugia malayi to develop and/or reproduce in the animal model after multiple inoculations for generations.

BACKGROUND: Traditional glass ion sealant has a poor abradability and a low rupture strength. The sealant on the occlusal surfaces easily fell off, and is difficult to replace resin sealant. OBJECTIVE: To observe the effects of traditional resin sealant and atraumatic restorative treatment (ART) glass ionomer-based pit and fissure sealant for the young children. METHODS: Randomized comparison method was used to compare ART glass ionomer-based pit on molars of one side with resin sealant on the opposite side in 89 3-year-old children. RESULTS AND CONCLUSION: The retention rates of ART glass ionomer sealant after 6 and 18 months were significantly lower than those of resin sealant (P < 0.05). The caducous position of ART gliass ionomer sealant was the second deciduous molar of the lower mandible, but the caducous position of resin sealant was the second deciduous molar of the upper mandible. The secondary caries rate of ART glass ionomer sealant was significantly lower than that of resin sealant at 6 months. No significant difference was determined between groups at 18 months. These suggest that ART glass ionomer pit and fissure sealant has lower drop-out rate, simple operation and low cost with excellent caries-preventing effect. Since it is economically superior to resin sealant, the method is worth popularizing in caries-preventing projects.

BACKGROUND: It has been reported that glass ionomer sealants have a poor wear resistance and low rupture strength that are easy to fall off on the occlusal surfaces. OBJECTIVE: To observe the effects of high-strength glass ionomer via the atraumatic restorative treatment (ART) on the pit and fissure of deciduous teeth in the young children. METHODS: A self-controlled method was used to compare ART glass ionomer-based pit and fissure seal on unilateral molars with resin sealant on the contralateral side in 89 children aged 3 years. RESULTS AND CONCLUSION: The retention rates of ART glass ionomer sealant after 6 and 18 months were 94.15% and 77.72%, respectively. At 6 months after treatment, ART gliass ionomer sealant was more caducous in mandibular second deciduous molars > mandibular first deciduous molars > maxillary second deciduous molars > maxillary first deciduous molars; at 18 months after treatment, the rank was mandibular second deciduous molars > maxillary second deciduous molars > mandibular first deciduous molars > maxillary first deciduous molars. The second deciduous molar of the lower mandible, but the caducous position of resin sealant was the second deciduous molar of the upper mandible. The caries prevalence rate of the deciduous teeth treated with ART glass ionomer sealant was significantly lower than that without sealant at 6 and 18 months (P < 0.01). These findings indicate that ART glass ionomer pit and fissure sealant is of a lower drop-out rate, easy to operate and of low cost with excellent caries-preventing effect.

In this study,adults of Armillifer agkistrodontis (A.agkistrodontis) were collected from Agkistrodon acutus,and then the eggs were separated to feed mice.In the next step,when the infection model was established,blood serum of infected mice were collected after 1,2 and 3 weeks,respectively.Furthermore,ELISA and dot- ELISA were used to detect the dynamic change of specific antibodies and circulating antigens respectively.The specific antibodies increased from 8th week,reached the top at 12th week,decreased from 16th week,and then maintain at the same level constantly.Meanwhile,the specific antibodies were typed.It is evident that IgM antibody appeared first.However,it was substitute by IgG1 after 16 weeks.Moreover,the circulating antigens have been detected in the 1st week by dot-ELISA.Then,the dilution between 1:8 to 1:128were founded in 3rd week.The highest dilution with 1:256 appeared at 8th week,maintained before 11th week and then decreased gradually,which might provide a significant clinical implication for early diagnosis of circulating antigens.
