Objective To observe the branches and distribution of the tibial nerve and analyze the compressed position of it.Methods Twenty sides of adult cadavers were anatomized and the tibial nerve branches in ankle,foot,the internal and external plantar tunnel were observed.Correlated data was measured and recorded.Results ① The tendinous part of abductor hallucis muscle that was located under the muscle and consisted the surface of the internal and external plantar tunnel was(8.62?0.79)cm in length,(3.01?0.30)cm in width,and the thickness of it was about(0.24?0.02)cm.The internal and external nerves were located in the internal and external tunnel.The length of the internal tunnel was about(4.58?0.41)cm,and the diameter was(1.11?0.10)cm.The length of the external tunnel was about(2.58?0.23)cm,the diameter was about(0.96?0.08)cm.② Internal hell nerve was in an isolated tunnel interior the hell,which was the hell tunnel.The length of the hell tunnel was about(3.03?0.21)cm,the diameter was(1.07?0.09)cm.Conclusion The tibial nerve branches can be compressed at internal,external plantar tunnel or the heel tunnel.When making neurolysis of the tibial nerve for tarsal tunnel syndrome patients,except for the flexor retinaculum,the internal and external plantar tunnel and the hell tunnel should also be decompressed especially for the patients with the symptom of compressed single branch.

Objective To establish a capillary gas chromatography method for the determination of trinitrotoluene (TNT) in workplace air.Methods Using dichloromethane as the eluent,the air was drawn through a glass fiber filter to collect TNT,TNT was extracted from the filter with dichloromethane by an ultrasonic shaker,and the sample was analyzed by OV-17 elastic quartz electron capture detector capillary gas chromatography.Results Under the optimal condition,the lowest detection limit was 0.006 ?g/ml,the lowest detection concentration was 0.001 3 mg/m~3 (based on 45 L air sample).When the concentration of standard solution was 0.040-2.0 ?g/ml,the linear equation was good,r=0.999 8,RSDs were between 0.66%-3.62%,the recovery rates were 90.4%-95.5%.When sample was collected by fiberglass filter paper,the efficiency of desorption was more than 90%,and was stable for at least 7 days at 2℃-8℃.Conclusion This method is applicable to the determination of trinitrotoluene in workplace air.

Objective To explore the long-term efficacy of botulinum toxin type A injections on facial beauty and its long-term safety.Methods A total of 33 beauty-seekers with botulinum toxin type A treatment for more than five years were reviewed as observation group,using digital muscle palpation meter (Myoton PRO) for the determination of the orbicularis oculi muscle and masseter muscle tension (F),the muscle characteristic parameters,such as muscle hardness (S) using a homemade facial questionnaire test for satisfactory rate of beauty from both beauty-seekers and physicians.At sametime,33 normal adults that never accepted botulinum toxin injection with matched age and gender were collected as control group.The same-sex indicators were dtermined and compared with using statistic analysis t test.Results The pairwised parameters of the same sex and site were comparied between the two groups;average F and S values in the observation group were lower than those of the control group,but no statistically significant difference were observed between the two groups (P＞0.05);in the observation group,average appearance age was 7.3 years younger than the control group,and the facial shape improved significantly.Conclusions Long-term and repeated application of botulinum toxin A is able to remove crow's feet and decrease the masseter and so the injection is safe with high satisfaction to beauty-seekers.

A commonly used Chinese crude drug Allii Macrostemonis Bulbus has been shown to possess good anticancer activities and related properties such as antioxidation, nitrite scavenging, nitrosamine synthesis blocking and immune enhancement, and has been widely used as an effective auxiliary drug in the treatment of some malignant tumors. This paper systematically reviews the advances in the study of anticancer-related activities of Allii Macrostemonis Bulbus's various components such as raw juice, extracts, saponins, volatile oil, polysaccharides, nitrogen compounds, etc.

Objective To analyze the expression of the placenta Grb10 from women conceived by transferred thawed blastocyst,and to evaluate the security of blastocysts vitrification.Methods A cross-sectional study was performed in the Department of Obstetrics and Gynecology of Fujian Provincial Maternity and Children's Hospital from January 2012 to May 2014,50 women conceived by transferring thawing blastocyst and 50 natural pregnancy control women were enrolled in this study.The expression of Grb10 protein was detected by immunohistochemistry and Western blot,and the expression of Grb10 mRNA was detected by Realtime PCR method.Results Comparison of two cases of gestational age,gestational age,fetal sex,fetal body weight,body length,head circumference,abdominal circumference,there were no significant differences(P＞0.05),comparison of placental area,placental weight,the difference was statistically significant(P＜0.05).Real-time PCR and Western blot results showed that,there was no significant difference in the expression of Grb10 mRNA and protein between the two groups(P＞0.05).Conclusion Blastocysts vitrification may increase the area and quality of delivery of placenta,however,there was no significant change in the expression of Grb10 in placenta.

Objective To explore the application value of 320-slice spiral CT myocardial perfusion technique in the evaluation of cardiac function in patients with coronary artery disease.Methods 24 patients with known reversible myocardial ischemia with coro-nary heart disease and 13 cases of normal were detected by 320-slice spiral CT myocardial perfusion scan in resting and after dobu-tamine-induced stress,measured the values of cardiac function indexes(ESV、EDV、SV、EF)in resting and after dobutamine-induced stress respectively,the results were analyzed by paired t test and independent sample t test,when the P value is less than 0.05,con-sidered statistically significant or correlation.Results The values of cardiac function indexes (ESV,EDV,SV)between the resting and after dobutamine-induced stress were significantly different except EF value in normal group.But only the EF value was signifi-cantly different in CHD,the rest values of cardiac function indexes(ESV,EDV,SV)no significant difference.Each corresponding value of cardiac function indexes in resting and after dobutamine-induced stress was significantly different between the CHD and the normal.Conclusion The dobutamine-induced stress myocardial perfusion with 320-slice spiral CT can judge the impaired degree of cardiac function in patients with myocardial ischemia,provide the basis for comprehensive evaluation of coronary artery disease and its prognosis.
