Objective To compare the clinical effects of electroacupuncture at antagonistic motor points and at acupoints on ankle varus post stroke. Methods 96 patients with ankle varus post stroke were randomly divided into treatment group (n=48) and control group (n=48). All the patients accepted Bobath approach. The treatment group accepted electroacupuncture at antagonistic motor points, while the control group at antagonistic acupoints. They were assessed with Holden functional ambulation category, modified Ashworth scale and dorsiflexion- eversion grade of ankle before and after 4 weeks of treatment. Results The ambulation, spasticity of ankle, and dorsiflexion-eversion of ankle improved in both groups after treatment (P<0.05), and improved more in the treatment group than in the control group (P<0.05). Conclusion Electroacupuncture at antagonistic motor points may release spasticity of ankle post stroke more effective than at acpoints

OBJECTIVETo investigate the potential of Gomphidius viscidus, a kind of ectomycorrhizal fungi, for phytoremediation of anthracene in soil.

METHODSAbsorptioe changes of micro-habitat were studied in detail.

CONCLUSIONEctomycorrhizal plants have a strong potential for remediation of polycyclic aromatic hydrocarn characteristics of both active and inactivated mycelia.

RESULTSA high calculated adsorption capacity of 1,886.79 mg/g and 1,515.15 mg/g at 25 °C, pH 6.0 for active and inactivated mycelia respectively, was obtained based on Langmuir model. The ANT biosorption was more ideally characterized by the Langmuir model than by the Freundlich model. The biosorption of anthracene to biomass was extremely fast and could be modeled with pseudo-second order adsorption kinetics. Moreover, ectomycorrhizal mycelia demonstrated a strong ability to adjust the physiological process to get adapted to the change of micro-habitat.

OBJECTIVETo explore the therapeutic effects of internal fixation with Herbert screws for the treatment of Pipkin type I and type II femoral head fractures.

METHODSFrom January 2008 to December 2012, 23 patients with Pipkin type I and type II femoral head fractures were treated with open reduction and internal fixation by Herbert screws through Kocher-Langenbeck approach. Twenty-three patients (aged 18 to 52 years with a mean of 35.5 years, including 18 males and 5 females patients, 8 left hips and 15 right hips) with femoral head fractures and posterior hip dislocation. The fracture was classified according to Pipkin classification based on the radiographic findings, 5 patients had type I and 18 had type II fractures. The duration time from admission to the operation ranged from 6 to 72 h (averaged 32 h). The clinical and radiographic outcomes of the patients were measured using Thompson-Epstein scoring scale. The Harris hip score(HHS) was used to evaluate and compare hip functions at the latest follow-up between affected and healthy sides.

RESULTSAll the patients were followed up, and the duration ranged from 20 to 48 months (averaged 30 months). According to Thompson-Epstein system, 12 patients got an excellent result, 6 good, 4 fair and 1 poor. The average HHS at the finial follow-up was 87.80 ± 8.46 (ranged from 66 to 95), which is similar to that in the healthy side 90.10 ± 6.35 (ranged from 72 to 98) (t = 1.044, P = 0.302). The complications such as deep infection, and deep vein thrombosis were not found. At the 3rd year during follow-up,4 patients had avascular necrosis of femoral head. At the 1st year of follow-up, 1 patient had hip pain after walking,screws loosening and shift after trauma,and serious complications of traumatic arthritis. All the 5 patients were treated with total hip arthroplasties.

CONCLUSIONThe treatment of internal fixation with Herbert screws through the Kocher-Langenbeck approach is effective for Pipkin type I and type II femoral head fracture. The method is reliable and valuable for recommendation. However, such fracture may have avascular necrosis of femoral head and complication of traumatic arthritis, which should be observed carefully in clinic with preparation of the prevention and treatment measures.

Objective To investigate the effects of maternal long-term exposure to low-dose trichlorfon on the serum paraoxonase (PON) activity of pregnant mice and development of embryos. Methods Female ICR mice (n=120) were randomly divided into control group and trichlorfon groups of different doses,and were managed by intragastric injection with trichlorfon of 0,2,10 and 50mg/kg,respectively. All the mice were managed once a day for a consecutive of 27 days,and were subjected to mating. The pregnant mice were continued to be managed with trichlorfon for 3 days,and were sacrificed on day 3 of gestation. The serum PON and acetylcholinesterase (AchE) activities were detected,and the development of embryos was evaluated. Results The serum PON activity of 2,10 and 50mg/kg trichlorfon group were (14.15?1.22),(12.78?1.80) and (10.45?1.95)IU/mL,respectively,and that of 50mg/kg trichlorfon group was significantly lower than that of control group [(13.37?2.31)IU/mL] (P0.05),while the the percentage of abnormal embryos of 50mg/kg trichlorfon group had an increased tendency. Conclusion Long-term exposure to low-dose trichlorfon can inhibit serum PON and AchE activity in pregnant mice without obvious effect on the development of embryos.

Objective To investigate the changes of thyroid hormone in peritoneal dialysis patients and analyse its impact factors, as well as the therapeutic effects of small dose of thyroxine.Methods 150 uremic patients in Hunan Provincial People’s Hospital from December 2013 to December 2014 were selected, 70 cases of uremia non-dialysis patients were divided into group A, while 80 uremia peritoneal dialysis for more than half a year were divided into group B.70 cases healthy examinees during the same period in our hospital were selected as control group ( group C ) . The total triiodothyronine (T3), total thyroxine (T4), free triiodothyronine (FT3), free thyroxine (FT4), thyroid stimulating hormone (TSH), hemoglobin (Hb), serum albumin (ALB), total cholesterol (TC), triglyceride (TG), serum creatinine (SCr), C reactive protein (CRP) and left ventricular ejection fraction ( LVEF) , subjective global assessment of nutritional act ( SGA) and other indicators were detected in three groups.Patients in group B were divided into two sub-groups according to thyroid hormone levels: B1 group had normal thyroid level while B2 abnormal.And the administration of small dose of thyroid hormone was given to patients in group B2, and the effect of the administration was evaluated by the above indexes.Results The FT3 in group A and B were significantly lower than that in group C (P<0.01).There were significant differences of levels of ALB, CRP, SGA between group B1 and group B2, and the FT3 level in group B was significant correlated with SGA, ALB, LVEF(r=0.815,P<0.001;r=0.780,P<0.001;r=0.953,P<0.001).After treated with small dose of thyroid hormone, FT3 and LVEF were improved while FT4, TSH, ALB, SGA, CRP were not improved in group B2.Conclusion The thyroid hormone level in patients with continuous ambulatory peritoneal dialysis decreases which is dominated with FT3.The decreased thyroid level is significantly correlated with nutrition ( ALB, SGA) and left ventricular function.The administration of small dose of thyroid hormone can improve the left ventricular systolic function.

The heat shock protein ClpB is a member of the Clp family and functions as molecular chaperones. ClpB is related to the acquired thermotolerance in organisms. A cDNA of 3144 bp was screened out of a tomato cDNA library. The polypeptide deduced from the longest ORF contains 980 amino acid residues, and was classified into HSP100/ClpB family based on the result of molecular phylogenesis analysis. Thus it was named as LeHSP110/ClpB according to its calculated molecular weight. LeHSP110/ClpB was characteristic of heat-inducibility but no constitutive expression, and was demonstrated to locate in chloroplastic stroma. An antisense cDNA fragment of LeHsp110/ClpB under the control of CaMV 35S promoter was introduced into tomato by Agrobacterium tumefactions-mediated method. At high temperature, the mRNA levels of LeHsp110/ClpB in antisense transgenic plants were lower than those in control plants. The PS II of transgenic plants is more sensitive to high temperature than that of control plants according to data of Fv/Fm. These results clearly showed that HSP110/ClpB plays an important role in thermotolerance of high plants.
