In freeze replicas of the hippocampus of guinea pig, gap junctions were observed on the E-face of the CA_1 pyramidal cells and the apical dendrites, the intramembranous particles aggregated as a large or a small area and arranged regularly or irregularly.

This paper gives a general introduction of HIV/AIDS treatment with Traditional Chinese Medicine (TCM) in China during the past 20 years. Although the role of TCM in treatment of HIV/AIDS is promising, there is still a long way to go.

In this paper, a method for dose calculation with pencil beam kernels constructed by point kernel superposition was proposed to accelerate the dose calculation during intensity optimization iteration. With this method, the direct aperture optimization method can be integrated in the planning system based on point kernel convolution/superposition model. The dose calculation time was also reduced during the iteration. From the result of the phantom and clinical patient data test, it was concluded that this method could be used for the intensity optimization of iteration dose calculation as the satisfied precision due to the optimization result coherence obtained. By implementing the method in the planning system product based on point kernel convolution/superposition model, a lot of additional research and development works for the pencil beam dose calculation model as well as the product maintenance cost can be avoided.

mTOR signaling pathway is a highly conserved intracellular signaling pathway,which partici-pates in several signaling pathways, such as PI3K/AKT/mTOR, AKT/TSC1-TSC2/Rheb/mTOR, LKB1-AMPK-TSC-mTOR and FGF-10-Spry2-mTORC1-STAT3/HIF-1α-VEGF-A. mTOR signaling implicate in the regulation of the development of lung and many pulmonary diseases in many aspects,may be connected to bron-chopulmonary dysplasia. Bronchopulmonary dysplasia is one of the very common chronic lung diseases in pre-term,physical and chemical factors have been shown to induce acute lung injury, aberrant wound healing and lung fibrosis in the immature lung. This review summarizes relationship of mTOR signaling among lung develop-ment,acute lung injury and lung fibrosis,to explore the role of mTOR signaling in the development of bronchop-ulmonary dysplasia,in hope of providing novel method in the prevention and treatment of bronchopulmonary dysplasia.

Dietary management plays an important role in the diabetes mellitus therapies. Effective dietary management can find the deficit of dietary management in patients with diabetes mellitus. Recently these tools primarily were consisted in the comprehensive diabetes mellitus management instruments and a fraction of the ones aim at the evaluation of the dietary management for diabetes. Timely and effective assessment of the effect on diabetes diet management depends on these tools. Therefore, the feasibilities, usefulness and deficit about these instruments were analyzed to prompt the application and investigation of the instruments in the future.

Objective: To evaluate dimensions of the nasopalatine canal and the relationship between the canal and the central incisors, and the canal and the crest, by using cone-beam computed tomography ( CBCT) . Methods:This study included 129 CBCTs, and the sagittal slices were used to measure the lower diameter ( Sda) , median diameter ( Sdb) , and higher diameter ( Sdc) , for calculating the average sagittal diameter ( Sd ); the coronal slices through canals were used to measure the lower diameter ( Hda) , median diameter ( Hdb ) , and higher diameter ( Hdc ) for calculating the average horizontal diameter ( Hd) , length ( H);the sagittal slices were used to measure the buccal bone thickness off the canal ( Bt) , and the distance to the crest off the lowest point ( At) , the horizontal slices were used to measure the distance between the canal and the central incisors ( Id) . These subjects were divided into two groups by gender;and divided into three groups by ages: (1) ≤30 years old, (2) 31 -50 years old, and (3) ≥51 years old. SPSS 17. 0 statistical software was used for statistical analysis. Results:The overall Sd was (3. 41 ± 0. 87) mm, the Hd was (5. 16 ± 0. 93) mm, and the difference was statisti-cally significant. The H was (14. 29 ± 3. 27) mm, the Bt was (7. 49 ± 1. 05) mm, the At was (8. 25 ± 1. 71) mm, and the Id was (2. 71 ± 0. 89) mm. Of the male and female, the Sd were (3. 64 ± 0. 90) mm and (3. 28 ± 0. 82) mm, P=0. 017; the Hd were (4. 98 ± 0. 89) mm and (5. 27 ± 0. 94) mm, P=0. 081;the H were (15. 47 ± 2. 75) mm and (13. 59 ± 3. 32) mm, P=0. 001;the Bt were (7. 90 ± 0. 96) mm and (7. 25 ± 1. 03) mm, P=0. 001; the At were (7. 41 ± 1. 86) mm and (8. 44 ± 1. 90) mm, P=0. 001; the Id were (2. 71 ± 0. 87) mm and (2. 72 ± 0. 91) mm, P =0. 983. Among the groups, no statistically significant differences were detected of the Sd (P =0. 325), of the Hd (P =0 . 636 ) , of the H ( P=0 . 292 ) , and of the Bt ( P=0 . 116 );statistically significant differences were de-tected of the At ( P=0 . 010 ) , and of the Id ( P<0 . 001 ) . Conclusion:The nasopalatine canal anatomy is highly variable. Gender is related to the nasopalatine canal length, Bt width, and At distance. While age was related to At, and Id, but no effect on nasopalatine dimensions. The CBCT is a useful device for studying the nasopalatine canal in three dimensions, prior to dental implant placement.

ObjectiveTo observe the clinical efficacy ofShu Feng An Shen(expelling wind and calming mind) needling plus distal points selection in treating cluster headache.MethodForty patients with cluster headache were divided into two groups by using random number table, 20 cases in each group. The treatment group was intervened byShu Feng An Shenneedling plus distal points selection, while the control group was by acupuncture with conventional points selection. The pain intensity score (Visual Analogue Scale, VAS), lasting duration and attack frequency were observed.ResultThe VAS score, lasting duration and attack frequency were significantly reduced after treatment in the two groups (P<0.01), and the reduction was more significant in the treatment group (P<0.01).ConclusionShu Feng An Shenneedling plus distal points selection can produce a more significant efficacy in reducing pain intensity, lasting duration, and attack frequency in treating cluster headache compared with acupuncture with conventional points selection.

Objective To demonstrate the effect of bilateral adrenalectomy (ADX) on the susceptibility to NMDA-induced seizure and hippocampal CRH mRNA in young rats. Methods 60 Wistar rats at P10 were divided into control group, ADX group and Sham-ADX group. In the next day after operation, 7 mg/kg NMDA was injected to induce seizure, and incubation period (in minutes) as well as degree was evaluated. In situ hybridization was used to detect hippocampal CRH mRNA expression. Results Latency was (43.65 ± 2.96) minutes in control group, (35.05 ± 2.35)minutes in ADX group and (42.60 ± 1.90)minutes in Sham-ADX group. Latency in the ADX rats increased significantly (F = 73.73, P < 0.05). The seizure scale was (4.40 ± 0.60) in control group, (5.56 ± 0.76) in ADX group and (4.55 ± 0.76) in Sham-ADX group. The severity of seizures in ADX group increased significantly compared with the control and Sham-ADX groups (F = 15.52, P <0.05). CRH mRNA expression was 20% in control group, 55% in ADX group and 15% in Sham-ADX group. CRH mRNA in the ADX group was significantly elevated (χ2 = 9.048, P < 0.05). Conclusion Adrenalectomy exacerbates NMDA-induced spasm seizures in young rats , which might be related to CRH mRNA expression in the hippocampus.
