Objective:To review the clinical efficacy of botulinum toxin type A(BTX-A)in the treatment of trigeminal neuralgia (TN).Methods:The main bibliographic databases were searched from English and Chinese literatures on the topic and the refer-ences of the identified articles were also searched for additional studies.2 reviewers assessed the quality of the included studies and extracted data duplicate.Results:3 Chinese and 1 English reports with 203 participants were included.However,substantial hetero-geneity(I2 =77%)precluded meta-analysis and the results were individually described.3 trials reported that BTX-A was more effec-tive than the control and 1 showed no difference between groups.Adverse effects of BTX-A were reported in 4 reports and were mild to moderate.Conclusion:BTX-A is effective in treating TN with few adverse effects.However,the evidence is weak because of a few studies included and most of them with low methodological quality.Further studies with high quality are needed to testify the evidence.

Objective To know the eutrophic state of Fenhe 1 reservoir. Methods The eutrophic level of Fenhe reservoir 1 was evaluated through measuring transparence,the total concentration of nitrogen(TN),phosphorus(TP),chlorophyll-a level(Chla) and the total count of the algal cells and calculating water TLI(∑). Results Water transparence in low water period was higher than that in common water period,TN concentration in low water period was higher than that in common water period,and it obviously exceeded the related standard limit in Surface Water Environment Quality Standard (GB3838—2002); TP concertration in common water period and low water period did not exceed the limit; Chla level was low;TLI(∑) in common water period and low water period was lower than 50. The total count of the algal cells was 1.67?106/L in low water period,which was much more than that(9.5?104/L) in the common water period. Conclusion Fenhe reservoir 1 is in mesotropher state.

Objective This paper aimed to evaluate the effect of preoperative embolization on the intraoperative blood loss of sacrum chordoma.Methods forty patients involved with the spinal chordoma were retrospectively analyzed in this study.The preoperative embolization group consisted of 16 sacrum chordoma patients were embolizationed by gelatin sponge particles (10 male and6 female)age from 35 to 71 years old,(mean 57.9 years) ; and the control group consisted of 4 sacrum chordoma patients (3 male and 1 female),age from 43 to 61 years old(mean 51.8 years).analyzed the predictive value of preoperative embolization in correlation with the intraoperative blood loss.Results The mean blood loss (2025.0 ±818.5)ml of sacrum chordoma in the preoperative embolization group was insignificantly than that (1950.0 ± 802.1) ml in the control group,(P ＞ 0.05).Conclusion The study shows that the preoperative feeding artery embolization of the spinal tumor has no significant effect on the intraoperative blood loss in the surgical excision of the sacrum chordoma.

AIM: To study the effects of disulfiram/copper complex (DSF/Cu) on ultrastructures and mechan-ical properties of human breast cancer and normal breast epithelial cells by atomic force microscopy (AFM) based on the nanoscale resolution and piconewton force measurement level.METHODS: The change of cell cycle and apoptotic rate of MCF-7 cells and MCF-10A cells induced by DSF/Cu were compared by flow cytometry.The cell surface morphology, ultra-structure, height, width and roughness were detected by AFM.The effects of DSF/Cu on the hardness (Young’s modu-lus) of the 2 kinds of cells were determined by AFM with indentation technique.RESULTS: DSF/Cu significantly in-duced apoptosis of the MCF-7 cells in a dose-dependent manner, whereas had little effect on the MCF-10A cells.The cell cycle analysis showed that DSF/Cu induced G2 /M arrest in the MCF-7 cells, but led to G0 /G1 arrest in the MCF-10A cells.The AFM images showed that the MCF-7 cells shrank and showed smaller and smoother morphology, and the filopo-dia were retracted obviously, even some became into lamellipodia, or disappeared completely after treated with DSF/Cu at concentrations of 400 and 800 nmol/L.The quantitative analysis indicated that the MCF-7 cells showed smaller width and
larger height, and the root mean square roughness and average roughness were decreased significantly in a dose-dependent manner after treated with DSF/Cu at concentrations of 400 and 800 nmol/L.However, little effect in the MCF-10A cells was observed.The biomechanics test at a single cell level demonstrated that the Young’s modulus of the MCF-7 cells and MCF-10A cells were both increased, yet the proportion increased in the MCF-7 cells was much higher than that in the MCF-10A cells after treated with DSF/Cu at concentrations of 400 and 800 nmol/L.CONCLUSION: DSF/Cu has strong antitumor effect on breast cancer with high efficiency and low toxicity by changing the properties of the biomechanics specifically.
