There are three major ways of for the treatments of post-stroke cognitive impairment.Medicine,acupuncture and the cognitive training is the most popular.Both clinical reports and experimental studies proved positive effect of acupuncture to post-stroke cognitive function impairment.There are more clinical reports and comprehensive mechanism studies on the Brain-activating and Orifice-opening Acupuncture than the other two popular treatments of acupuncture for cognitive function impairment.Acupuncture show positive effect on post-stroke cognitive function impairment.Further studies are required to validate whether acupuncture has better curative effect than cognitive training.

A rapid and sensitive liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS) method for quantification of sitagliptin in human plasma and urine had been developed. This method was applied to the pharmacokinetics study of sitagliptin tablet after single- and multiple-dosing in Chinese population. Plasma samples were prepared by a liquid-liquid extracted method, and urine samples were diluted. Compounds were analyzed by multiple reaction monitoring (MRM) mode with a electrospray ionization (ESI) interface. Mobile phase consisted of methanol and water (85 : 15, v/v). The linear concentration range of calibration curve was 0.5-1 000 ng.mL-1. and 0.2-100 µg.mL , intra-run/between-run accuracy was 98.98%-103.69% and 97.63%-102.29%, intra-run/between-run precision was <5.51% and 4.26% for plasma and urine sample, respectively. The stability of sitagliptin stock solution was tested for 55 days at -30 °C. Sitagliptin was stable when stored under the following conditions: 24 hours in the autosampler after sample preparation; 24 hours at room temperature, after 3 freeze and thaw cycles (from -30 °C to room temperature), 40 days at -30 °C for plasma and urine samples. The absolute recovery in plasma was 71.1%, and no matrix effect was founded. This method was proved simple, specific, sensitive, rapid and suitable for pharmacokinetics study of sitagliptin in human being.

Objective To investigate the effect of different temperature moxibustion on serum IL-1β, IL-2 and TNF-αcontents in acute adjuvant arthritis rats and provide a basis for the mechanism of local anti-inflammatory and immune action of moxibustion. Methods A rat model of adjuvant arthritis (AA) was made by Freund’s complete adjuvant (FCA) modeling method. Of 32 SD rats, 8 were randomly selected as a normal group and the other 24 for model making. After successful model making, the rats were randomly allocated to model, treatment 1 and treatment 2 groups, 8 rats each. Treatment 1 and 2 groups received moxibustion. Local temperature at moxibustion point was controlled at (38±1)℃in treatment 1 group and at (45±1)℃in treatment 2 group. Rat serum IL-1β, IL-2 and TNF-αcontents were measured by enzyme-linked immunosorbent assay (ELISA). Results There were statistically significant differences in serum IL-1β, IL-2 and TNF-αcontents between the model, treatment 1 or treatment 2 group and the normal group (P<0.01). There was a statistically significant difference in serum IL-2 content between treatment 1 and the model groups (P<0.01). There were statistically significant differences in serum IL-1β, IL-2 and TNF-αcontents between treatment 2 group and the model or treatment 1 group (P<0.01). Conclusions Moxibustion has a reducing effect on serum IL-1βand TNF-αcontents and a raising effect on IL-2 content. 45℃moxibustion temperature can improve the effect of moxi bustion. The anti-inflammatory action of moxibustion may be through the mechanism of reducing serum IL-1βand TNF-αcontents and raising IL-2 content, which relieve body inflammatory reaction. The action of moxibustion needs proper moxibustion temperature.

As an important indicator of total hip arthroplasty (THA) the rate and degree of offset reconstruction play an important role in improving the prognosis and life quality of patients. The reconstruction of femoral offset is closely related to reserved length of calcar femorale, the head and neck length of prosthesis, angle degree of neck shaft and whether lower limb is isometric. Reconstruction strategy includes making a meticulous and standard measurement before the surgery, predicting the reserved length of calcar femorale, selecting a prosthesis with approximate anatomical neck-shaft angle and reconstructing offset by adjusting the head and neck length of the prosthetic during the operation. The aim of this article was to introduce the research progress and influence of offset on hip function, prosthetic wear and postoperative complications such as pain, limp and unequal leg length, and to discuss the reconstruction strategy.

BACKGROUND: Percutaneous kyphoplasty (PKP) and percutaneous vertebroplasty (PVP) have been shown to obtain satisfactory clinical efficacy in the treatment of spinal sandwich fracture compared with conventional conservative method, but a further investigation on the related biomechanical characteristics is required. OBJECTIVE: To compare the biomechanics characteristics of PVP and PKP for spinal sandwich fracture. METHODS: The finite element models of PVP and PKP were constructed based on the finite element model of spinal sandwich fracture. The deformation and stress distribution characteristics were analyzed after loaded. RESULTS AND CONCLUSION: After PVP for L1, T11sandwich fracture, the stiffness at the thoracic and lumbar segments, the maximum stress and deformation at the sandwich vertebrae showed no obvious improvement, and the stress concentration at the anterior column of sandwich vertebrae was not improved significantly (from 26.12 Mpa to 23.37 Mpa, reduced by 10.53%). Meanwhile, PKP significantly increased the stiffness at the thoracic and lumbar segments, the maximum stress and deformation of the sandwich vertebrae were significantly decreased (from 27.15 Mpa to 17.52 Mpa, reduced by 36.71%).

OBJECTIVETo observe the hypotensive effects of Qindan Capsule (QC) on spontaneous hypertensive rats (SHR) and its effect on the contents of endothelin (ET), calcitonin gene-related peptide (CGRP) and angiotensin-II (Ang-II ) in plasma and vascular tissues, and to investigate the possible mechanism of QC in lowering blood pressure.

METHODSForty SHRs were divided into 5 groups: the high dosage QC group [QCHD, 750 mg/(kgxd)], the low dosage QC group [QCLD, 150 mg/(kgxd) ], the Niuhuang Jiangya Pill group [NJP, 200 mg/(kgxd) ], the Captopril group [ 15 mg/(kg d) land the model group, 8 in each group. Meanwhile, a normal control group consisting of 8 Wistar-Kyoto (WKY) rats was set up also. All the rats were administered with medicine through gastrogavage. Systolic blood pressure (SBP), level of ET, CGRP and Ang-II in plasma and Ang-II in tissues of mesenteric artery were detected in all the rats after 12 weeks of treatment.

RESULTSThe level of SBP after treatment in the QCHD group was lower than that in the model group (P<0.01), but with no significant difference as compared with that in the Captopril group and the NJP group (P>0.05). After treatment, the plasma level of ET was lower and CGRP higher than those in the model group (both P<0.05), and also higher than those in the NJP and Captopril group (both P<0.05). As for the content of Ang-II , in mesenteric arterial tissues, it was lower in the QCHD group than that in the model group ( P<0.05), but in plasma, it showed no significant difference between the two groups (P>0.05).

CONCLUSIONQC has a satisfactory hypotensive action on SHR rats, and its mechanism may be associated with the regulation on plasma vasoactive peptide and regional renin-angiotensin system.
