The first metatarsophalangeal joint bending plays an important role in the foot movement. However, the existing researches mainly focused on the movement scope of the joint and the clinical treatments of related foot diseases. In order to investigate the effects of the first metatarsophalangeal joint bending on human walking gait stability, the present researchers recruited 6 healthy young men to perform the first metatarsophalangeal joint constraint (FMJC) and barefoot (BF) walking tests. Data of the temporal and spatial parameters, the joint angles of lower limbs, the ground reaction forces (GRF) and utilized coefficients of friction (UCOF) were collected and analyzed. The results showed that, since hip and knee could produce compensation motions, the FMJC had no significant effects on waking gait, but the slip and fall probability increased significantly.

Objective To investigate the effect of nuclear factor-?B(NF-?B) on the regulation of cyclooxygenase-2(COX-2) and Caspase-3 in hippocampal neurons after traumatic brain injury(TBI) in rats,and explore the neuroprotective effect and the possible mechanism of progesterone(PROG) in hippocampal neurons after TBI.Methods Forty-five male Spraque-Dawley rats were randomly divided into 3 groups: sham-operated group(n=15),TBI group(n=15) and PROG-treated group(n=15,intraperitoneal injection of PROG 16 mg/kg in 1 and 6 h after injury).The rat model of TBI was duplicated with the improved Feeney's method.The rats were sacrificed in 24 h after injury and their brain was resected.Nissl staining,immunohistochemical staining and Western blot assay for NF-?B,COX-2 and Caspase-3 was used to observe the changes of positive cell numbers and protein levels in the hippocampal neurons.Results The numbers of immunoreactive neurons to NF-?B(24.0?2.5),COX-2(35.9?2.7) and Caspase-3(25.1?2.7) were significantly increased in the hippocampus at 24 h after TBI when compared with the positive neuron numbers of NF-?B(1.9?0.9),COX-2(1.5?0.7) and Caspase-3(1.8?0.8) in sham group.After the treatment of PROG,the positive cell number of NF-?B(14.2?1.8),COX-2(16.6?2.7),Caspase-3(11.2?2.4) was reduced obviously as compared with the TBI group(P

AIM　To discuss the intraspecific relationship in Magnolia officinalis and the genuineness of Cortex Magnoliae officinalis, and to find some DNA characters of certified “Houpo”. METHODS　Thirty-three samples from eleven locations, which can represent most of the distribution of M.officinalis, were selected. The total DNA was extracted. Severty-four random primers were tried to get good amplification. RESULTS One hundred and sixteen bands amplified from seventeen primers, were clustered by NTSYS-pc software. Three branches were obtained. Some distinctive primers and bands, which represent certified species or fine breed, were obtained also. CONCLUSION　1) M.officinalis should be divided into three geographic clans instead of two subspecies or varieties, they are, a) typical officinalis, b) typical biloba and c) Middle type. This conclusion agrees with the leaf form and other characters. 2) The genetic difference between “Chuanpo” and “Wenpo” is evident and the difference is in correspondence with the quantities of their chemical constituents. So, the genetic difference is the main reason of the genuineness of Cortex Magnoliae officinalis. 3) These results may be used to establish DNA database for identification of Cortex Magnoliae officinalis.

BACKGROUND: It has been thought that posterior cervical decompression increases the risk of cervical instability and the stress on posterior longitudinal ligament may change growth factor expression in vivo. However, the association between BMP-4 expression and heterotopic bone formation has not been confirmed. Bone morphogenetic protein 4 (BMP-4) is one of factors that can lead to heterotopic bone formation alone.OBJECTIVE: To observe the effects of posterior cervical decompression on BMP-4 mRNA expression in the posterior longitudinal ligament.DESIGN, TIME AND SETTING: A randomized controlled animal experiment was performed in Taishan Medical College between January 2005 and December 2006.MATERIALS: A total of 48 adult Sprague Dawley rats of either gender and of clean grade, weighing 270-350 g, were included in this study.METHODS: All rats were randomly and evenly divided into 3 groups: experimental, sham-operated, and blank control. In the experimental group, C36 laminectomy for decompression was performed.In the sham-operated group: only skin incision was made. Rats in the blank control group received no any treatment. Four rats were allocated for each time point (1, 2, 4, and 8 weeks post-surgery) for harvesting posterior longitudinal ligament.MAIN OUTCOME MEASURES: Detection of BMP-4 mRNA expression in the cervical posterior longitudinal ligament by semi-quantitative reverse transcription-polymerase chain reaction.RESULTS: In the experimental group, obvious BMP-4 mRNA expression was found at 1-8 weeks post-surgery. While no BMP-4 mRNA expression was found at all times in the sham-operated and blank control groups.CONCLUSION: Posterior cervical decompression can increase BMP-4 mRNA expression in the posterior longitudinal ligament.Endogenous BMP-4 may contribute to ligamentous ossification and development post-surgery.

Objective To evaluate the effect of hyperthermic intraperitoneal perfusion on blood coagulation in patients undergoing laparoscope-assisted radical surgery for gastric cancer.Methods Forty patients of both sexes, aged 40-60 yr, weighing 50-80 kg, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ , undergoing elective radical surgery for gastric cancer, were equally randomized into control group (group C) and hyperthermic intraperitoneal perfusion group (group HIP).The patients were treated with hyperthermic intraperitoneal perfusion for 1 h after the end of the radical surgery in group R.Before induction of anesthesia (T0) , immediately before hyperthermic intraperitoneal perfusion (T1), and at 1 h of hyperthermic intraperitoneal perfusion (T2) , venous blood samples were collected, blood coagulation was measured using thromboelastography, and the reaction time, coagulation time, α angle and maximal amplitude were recorded.Results Compared with group C, no significant change was found in blood coagulation parameters at T0 and T1 (P＞0.05), the reaction time and coagulation time were significantly increased, and α angle and maximal amplitude were decreased at T2 in group HIP (P＜0.05).Conclusion Hyperthermic intraperitoneal perfusion can improve blood coagulation in the patients undergoing laparoscope-assisted radical surgery for gastric cancer.

Objective To explore the effect of Astragalus polysaccharides (APS) on the function and quantity of islet β cells in rats with type 2 diabetes mellitus (T2DM). Methods SD rats were randomly divided into normal control group, T2DM model group and APS treatment group, with 8 rats in each group. The T2DM rats in the T2DM model group was induced by the combination of high fat diet and streptozotocin, and the rats in the APS treatment group was treated with APS (700 mg·kg-1·d-1, content of APS being 70%). The rats were sacrificed after 8 weeks of drug intervention, and the serum samples were collected to measure fasting blood glucose (FBG), triglyceride (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) and fasting insulin (FINS), and to calculate insulin secretion index (HOMA-β value). Pancreas tissues were extracted and stained with Hematoxylin-Eosin to observe the pancreatic histopathological characteristics, and the quantity of islet β cells was observed and calculated with immuno-histochemical method. Results (1) Compared with the normal control group, the rats in T2DM model group had significant increases in the FBG, TG and LDL-C, and significant decreases in the HDL-C, FINS and HOMA-β (P<0.05); compared with the T2DM model group, the rats in APS treatment group had significant decreases in the FBG, TG and LDL-C (P<0.05), and significant increases in the FINS and HOMA-β (P<0.05). (2) Compared with the normal control group, the rats in T2DM model group showed a significant atrophy of the islet accompanied by loss of granular and vacuolar degeneration, and the number of the islet β cells was significantly reduced (P<0.05); compared with the T2DM model group, the rats in APS treatment group showed a significant increase in the islet volume accompanied by improvement of islet degranulation and vacuolar degeneration, and had a significant increase in the number of islet β cells (P<0.05). Conclusion APS can improve the glucose and lipid metabolisms of the T2DM rats, which may be caused by increasing insulin secretion through the protective effect on pancreatic islet β cells.

Puerarin (PUE), as an isoflavone component, has a wide range of pharmacological activities, while its poorly aqueous solubility limits the development of solid oral dosage forms. In this study, PUE along with nicotinamide (NIC) were prepared into the coamorphous system by solvent-evaporation method and characterized by powder X-ray diffraction (PXRD), differential scanning calorimetry (DSC) and Fourier transform infrared spectroscopy (FT-IR). In addition, its dissolution behavior and solubilization mechanism were also investigated. PUE-NIC coamorphous was a single homogeneous binary system, with a single glass transition temperature at 35.1 ℃. In comparison to crystalline PUE, during the dissolution process, coamorphous PUE-NIC not only exhibited the "liquid-liquid phase separation" (LLPS) phenomenon, but the formation of A_p type complexation (1∶1 and 1∶2) between PUE and NIC molecules was also verified, which significantly improved the solubility of PUE and prolonged the supersaturation time, and would benefit its absorption.
