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.

ObjectiveTo examine the effects of temsirolimus, an inhibitor of mammalian target of rapamycin, on bladder cancer cell lines T24 and BIU-87 in vitro and in vivo for purpose of evaluating the probability of mTOR targeted therapy for bladder cancer.MethodsAfter being treated by a different concentration of temsirolimus, T24 and BIU-87 cells were tested by MTT assay for cell proliferation activity.Cell cycle and apoptosis analysis were performed with flow cytometer. Wound scratch assay was used for cell migration activity and transwell motility assay. Western blot analysis was used to test the mTOR phosphorylation. Subcutaneous inoculation of 6-week-old nude mice was performed using 1 × 106 T24 cells in 50% matrigel for both control (n = 10) and temsirolimus (n = 10) groups. The volume of tumors was examined and then the expression of Ki-67 was detected by immunohistochemistry.ResultsTemsirolimus significantly inhibited proliferation of T24 and BIU-87 cells in a dose- and time-dependent manner. After administration of temsirolimus on T24 and BIU-87 cell lines for 24 h, the rate of wound healing in 0 nmol/L groups were (88.9 ± 14. 1 ) % and ( 83.6 ± 16.3)% , which were higher than in the 5 nmol/L groups, which were (42.7 ± 11.6) % and ( 36.9 ± 9.7 ) % ( P < 0.05 ). In the transwell motility assay, the number of cells in the 0 nmol/L group was 26.5 ± 5.8 and 28.2 ± 4.6, which was higher than in the 5 nmol/L group ( 19.0 ±3. 8 and 21.3 ± 5.1, respectively) (P < 0. 05). When temsirolimus was administered on T24 and BIU-87 cell lines for 48 h the percentages of cells delayed in phase G0/G1 in 5 nmol/L group were ( 77.46 ±6.11)% and (73. 39 ± 4. 94)% respectively, and higher than in the 0 nmol/L group, which were (65.99 ±5.01 )% 、(60.15 ±3.98)% (P <0.05). There was no statistically significant difference in the apoptosis rate between the two groups (P > 0.05 ). In Western blot analysis, the ratios of p-mTOR/β-actin were 0.92 ±0.09 and 1.01 ± 0.08 in 0 nmol/L group, and higher than in the 5 nmol/L group (0.47 ±0.05、0.04 ±0. 01 ) (P < 0.05 ). After administration of temsirolimus for 21 days, the tumor volume in nude mice in the control group were 351.1 ± 139.9 mm3 , which was larger than 351.1 ± 139.9 mm3 in the temsirolimus group ( P < 0.05 ). The positive rate of Ki-67 expression was ( 67.3 ± 8.4 ) % in the control group, which was higher than in the temsirolimus group ( 35.5 ± 6.7 ) % ( P < 0.05 ).ConclusionsThis study provides in vitro and in vivo evidence that temsirolimus may inhibit the viability of bladder cancer cells and temsirolimus could be exploited as a potential therapeutic strategy in bladder cancer.

The high molecular weight glutenin subunits (HMW-GS) are the main components of storage proteins of wheat,and play a critical role in determining the visco-elastic properties of gluten. There are both quantitative and qualitative effects of HMW-GS on the processing properties of wheat. Current knowledge of the molecular structures,compositions and properties of the gluten proteins of wheat is summarized in details,and the role of the HMW-GS in determining the quality of the grain for breadmaking and how their amount and composition can be manipulated leading to changes in dough mixing properties is also discussed systematically.

The source of seed cells has always been the major problem in cartilage tissue engineering.Bone marrow stromal cells (BMSCs) have gradually become an optimal source of seed cells for cartilage engineering due to their high proliferative potential,multi-lineage differentiation potential and easiness to be obtained with minute trauma.The great challenge is how to get abundant BMSCs with a high purity and how to induce them in vitro into chondrogenic phenotype.This review aims to discuss the various strategies that can induce BMSCs chondrogenic differentiation in vitro so as to offer beneficial reference for constructing cartilage with BMSCs as seed cells.

Objective To study prevention and treatment for patients during the intermittent period of maintaining hemodialysis complicated by acute left heart failure. Methods The treating process of 126 examples suffered from acute left heart failure during the intermittent period of 14 225 person-time maintaining hemodialysis in 143 patients were retrospectively analyzed. Results In this case group, 0.89% suffered from acute left heart failure during the intermittent period of hemodialysis and the successful rescuing rate was 88.9%. Conclusions Applying the treatment of emergency hemodialysis, quickly filtering body fluid, the curative effect is reliable and rapid. It is one of the best ways to cure patients suffered from acute left heart failure during the intermittent period of maintaining hemodialysis. Combined with other treatments, it will be able to improve the successful rate, and ensure the sufficiency of hemodialysis. United with other steps of reducing blood pressure, such as using angiotensin converting enzyme inhibitors, angiotensin II receptor blocker, and ? receptor blocker, it is an effective countermeasure to prevent patients suffering from acute left heart failure during the intermittent period of maintaining hemodialysis, and effectively reduces its appearance as well.

Sailuotong (SLT) is a compound preparation composed of ginseng, ginkgo and saffron for the treatment of vascular dementia In order to identify its material foundation and provide evidence for therapeutic regimen, the pharmacokinetics and brain distribution of ginsenosides were investigated after intragastric administration of SLT. An LC-MS/MS method was developed for the determination of 7 ginsenosides in rat plasma simultaneously. Statistical analysis of obtained data demonstrated that the method has achieved the desired linearity, precision, accuracy and sensitivity. After administration of SLT at 60 mg x kg(-1) dose, 7 ginsengosides were all absorbed into systematic circulation. The quantitative and statistical analysis of gensenosides in plasma showed that protopanaxdiol saponins exhibited higher concentration and longer half life than protopanaxatriol saponins. The mean value of half life of ginsenosides Rg1, Re, Rb1, Rb2/b3, Rc and Rd were 15.26, 2.46, 18.41, 27.70, 21.86 and 61.58 h respectively. The peak concentration of them were 7.15, 2.83, 55.32, 30.22, 21.42, 8.81 microg x L(-1) respectively. The determination of brain distribution at different time after dosing revealed ginsenosides entered into brain promptly but the concentration declined along with time rapidly. The ginsenosides with higher concentration in brain were Rg1, Re, Rb1 and Rc. These findings demonstrated ginsenosides could be absorbed in blood and penetrated into brain rapidly. Some ginsenosides, especially Rg1 and Re, might be the main components directly effecting neurocyte in brain taking advantage of their better brain distribution. While ginsenosides of mostly protopanaxdiol saponins might protect brain mainly depending on peripheral efficacy in virtue of their long residence in blood, by which higher concentration could be reached after multiple dosing.
