Objective To apply a hand function laserimager to evaluate the effect of acupuncture on hand dysfunction after stroke. Meth-ods From January to June, 2016, 18 stroke patients with upper limb dysfunction were divided into control group (n=9) and acupuncture group (n=9). The control group received routine medication and rehabilitation, while the acupuncture group received acupuncture in addi-tion. They were assessed with modified Ashworth Scale (MAS), Fugl-Meyer Assessment (FMA) of upper limb motor function and modified Bathel Index (MBI) before and after three-week treatment, while the region of interest (ROI) of their hands was tested with the hand func-tion laserimager. Results The scores of MAS and FMA improved after treatment in both groups (t>4.44, P<0.01), and improved in the score of MBI in the acupuncture group (t=3.95, P<0.01). The scores of MAS, FMA, and MBI improved more in the acupuncture group than in the control group (t>3.17, P<0.01). Meanwhile, the scores of ROI decreased in the affected hands after treatment (t>7.78, P<0.001), and de-creased more in the acupuncture group than in the control group (t=-2.23, P<0.05). No significant difference was observed in the scores of ROI of the unaffected hands (t=-0.11, P>0.05) between groups. Conclusion The hand function laserimager, which responds to the blood perfusion of the hand, can be used as a tool to evaluate the hand function.

Objective To study the influence of different body serum iron levels on follicle stimulating hormone (FSH),luteinizing hormone (LH) and uterine ovarian index,and explore the body serum iron level effects on female mice sexual maturity further.Methods 36 three weeks C57BL/6J female mice were randomly divided into the normal control group,strengthen-iron 1 group and strengthen-iron 2 group,12 cases in each group.The normal control group with normal diet(310mgFe/kg),strengthen-iron 1 group and strengthen-iron 2 group were given high -iron diets(respectively with 465mgFe/kg and 620mgFe/kg) after born 3 weeks.each group body,uterus and ovary mass after 2 weeks were checked;colorimetric method was used to detect the serum iron level;the serum follicle stimulating hormone (FSH) and luteinizing hormone(LH) were detected by chemiluminescent immunoassay.Results The body of mice serum iron levels,uterine ovarian index (uterine ovarian wet mass/body mass) and follicle stimulating hormone(FSH) level of strengthen-iron 1 group and strengthen-iron 2 group were higher than those of normal control group (F =9.11,11.11,7.09,all P ＜ 0.01).Luteinizing hormone (LH) level of the strengthen-iron group was higher than those of normal control group (F =3.89,P ＜ 0.05).Conclusion Uterine ovarian index,follicle stimulating hormone level and luteinizing hormone level were affected with increased serum iron level;It suggests that the increasing serum iron level can cause female mice sexual maturity in advance.

Evaluation of the permeability mainly focuses on intestinal absorption in biopharmaceutics classification system (BCS). It is more complicated that the absorption and metabolism under multicomponent environment in biopharmaceutics classification system of Chinese materia medica (CMMBCS) compared with single component environment, which needs suitable mathematical models to be described. Therefore, with full consideration of existing single component mathematical algorithm combining with the characteristics of intestinal absorption and metabolism, we explored and designed a new mathematical algorithm of intestinal absorption and metabolism of multicomponent drug. Then we put forward a new coefficient, P (influence), the relative change rate of the single component's intestinal absorption and metabolism under multicomponent environment compared with single component environment, which described the influences of intestinal absorption and metabolism of the component under multicomponent environment. Moreover, P (influence) highlights the distinctive characteristics of multicomponent drug's intestinal absorption and metabolism, and lays the foundation for the construction of CMMBCS.

OBJECTIVETo study cognitive function and cerebral metabolic changes in patients with transient global amnesia (TGA).

METHODSThree patients with TGA were given mini-mental state examination (MMSE), revised Wechsler memory scale (WMS-R) examination and magnetic resonance imaging (MRI) scans after they had been diagnosed as TGA. Using (18)F labelled deoxyglucose as tracer, patients were given a positron emission tomography (PET) examination at different periods during recovery.

RESULTSNo obvious abnormality was found in MMSE and MRI scans in the three patients. However, WMS-R examination and cerebral PET imaging displayed cognitive dysfunction of varying degrees and low metabolism in local areas related to memory in 2 of 3 patients.

CONCLUSIONSIn TGA patients, cognitive function and cerebral metabolic levels are closely correlated with duration of symptoms. It is necessary to stop the TGA attack as quickly as possible early time.

Objective:To explore the protective effect of agmatine on mice with multiple organ failure (MODS) induced by yeast polysaccharide(ZYM) on the expression of inflammatory factors.Methods:ZYM induced inflammation model was established by intraperitoneal injection of ZYM in mice.All mice were divided into blank group,ZYM group and ZYM+AGM group.The mice feeding, white cell count,heart rate and so on were observed before and after the modeling to determine whether the model was successful.The liver function of mice,renal function,myocardial enzymes and other biochemical indicators were detected after the success of the model;and through the qPCR and ELISA method for detection of blood tumor necrosis factor alpha (TNF-alpha),interleukin 1 beta (IL-1 beta),interleukin 6 (IL-6),IL-10 gene and protein secretion level.Results: After the injection of ZYM,mice looked disorganized, activity and reduce consumption;the functional serological indexes of various organs of the mice were detected,which showed that the function of the viscera was serious.Compared with the blank control group,the serum parameters of ZYM group and ZYM+AGM group were significantly higher,and the inflammatory factors TNF-α,IL-1,IL-6 and IL-10 were significantly increased (P<0.05).Compared with ZYM group,ZYM+AGM serum markers of organ function decreased,inflammatory factor TNF-α,IL-1β,IL-6 decreased significantly (P<0.05),while there was no significant difference in IL-10 (P>0.05); and the mouse spirit,eating and activity had no significant change.Conclusion:Intraperitoneal injection of 500 mg/kg ZYM can successfully construct a model of MODS,AGM by reducing the release of inflammatory factors,play a protective role in the function of various organs of MODS mice.

OBJECTIVE: To investigate the changes of electrode impedance, THR/MCL values, and dynamic range (DR) in Combi 40+ cochlear implant after implantation. METHOD: A respective study was carried out collecting 20 consecutively implanted children's electrode impedances, THR/MCL values, and DR at seven time point during the first three years after implantation. Their variation and correlations were analyzed. RESULT: Overall, electrode impedances were lowest during the operation, and significantly rise to the highest at the first stimulation, then followed by a gradual decrease. After three months, electrode impedance of apical and medial cochlear segment were basically stable, while that of the basal segment was gradually increased. Dynamic range (DR) of apical and medial group electrode increased early after the operation and showed a stabilization from the second year, whereas that of basal group have a downward trend since the first year. However, the electric charge of each group increased significantly after three months, and then become stable after first year. Otherwise, a stronger negative rectilinear correlation was found between impedance changes with DR than with THR/MCL level. CONCLUSION The electrode impedances vary clue to different electrode position. Measuring the electrode impedance can effectively evaluate the working status of Combi C40+ cochlear implant. The dynamic range of the electrode was negatively correlated with the impedances, which made it possible to predict the width of the dynamic range by measuring the impedance 3 or 6 months after operation.

Objective Cold knife conization combined with frozen section were usually used in assessing the severity of the disease and the scope of the operation in cervical intraepithelial neoplasia class Ⅲ (CIN Ⅲ) patients before the total hysterectomy.In this study,LEEP biopsy combined with frozen section was used for preoperative assessment in CIN Ⅲ patients.The clinical value of this approach in assessing disease severity and operation scope before total hysterectomy will be analyzed.Methods We retrospectively analyzed the results of colposcopy biopsy,LEEP biopsy frozen sections,paraffin sections and postoperative residual cervix pathological biopsy in 168 cases with CIN Ⅲ admitted to our hospital from January 2011 to December 2012.Results LEEP biopsy combined with frozen sections showed that 64.88％ (109/168) results of frozen section were consistent with the results of cervical colposcopy biopsy,22.02％ (37/168) were degraded and 13.09％ (22/168) were upgraded to microfocal invasive cancer or invasive cancer.The pathological results of paraffin section showed that 109 cases(64.88％) of CIN Ⅲ lever,33 cases (19.6％) of inflammatory and CIN Ⅰ-H,26 cases (15.4％) of micro invasive carcinoma and invasive carcinoma were consistent with the results of cervical colposcopy biopsy.The accuracy of LEEP frozen biopsy was 95.2％ (κ=0).Among the 146 residual cervixs of CIN Ⅲ patients diagnosised by LEEP biopsy,51.3 ％ (75/146) had pathological changes.Comparison of cervical col poscopy biopsy and final diagnosis,26 cases of invasive cancer were missed diagnosis by cervical colposcopy biopsy.Conclusion LEEP biopsy combined with frozen section can provide a quick and accurate assessment before cystectomy in CIN Ⅲ patients.It is feasible to determine the surgical range according to frozen section biopsy.

To research the effect of Ginseng Radix et Rhizoma and Aconiti Lateralis Radix Praeparata compatibility on cardiac toxicity in rats by UPLC-Q-TOF/MS, and explore the endogenous markers and molecule mechanism. Different compatibility of Shenfu decoction were given to male Wistar rats at dosage of 20 g · kg(-1) for 7 days, collected the serum, and analyze the endogenous metabolites effected by Shenfu formulation by principal component analysis and partial least-squares analysis. Results showed that content of glutathione, phosphatidylcholine and citric acid decreased in mixed-decoction group, while ascorbic acid, uric acid, D-galactose, tryptophan, L-phenylalanine increased. The results showed cardiac toxicity of Aconiti Lateralis Radix Praeparata in Shenfu mixed-decoction. Shenfu co-decoction group showed a similar or weaker trend compared with control group, but most of them do not have a statistically significant. The results indicated the scientific basis of Shenfu compatibility by comparison of co-decoction group with mixed-decoction group. Shenfu compatibility can reduce cardiac toxicity induced by Aconiti Lateralis Radix Praeparata, and citric acid, glutathione, phosphatidyl choline, uric acid might be regarded as potential markers of cardiotoxicity.

OBJECTIVETo evaluate the clinical significance of IgH and TCR gamma gene rearrangement in plasma free DNA in patients with non-Hodgkin Lymphoma (NHL).

METHODSPlasma free DNA in 74 patients with NHL were extracted and identified by Globin gene. IgH (FR3A/VLJH), TCR gamma (TVG/TJX) clonal rearrangements were amplified by PCR and compared with results of mononuclear cell DNA and pathological biopsy sample DNA.

RESULTSPlasma free DNAs were successfully obtained from 58 cases (35 B-NHL and 23 T-NHL) of newly diagnostic, refractory and relapsed NHL out of total 74 patients (78.4%), but not found in the rest 16 patients in remission. Of 35 B-NHL cases, 31 showed IgH rearrangement (88.6%), and none with TCR gamma rearrangement; of 23 T-NHL cases, 8 showed TCR gamma rearrangement (34.8%), and 2 with IgH gene rearrangement synchronously. In comparison with the results of IgH and TCR gamma gene rearrangement in biopsy samples in 30 B-NHL cases, 26 cases in plasma free DNA (86.7%) and 24 in biopsy samples (80%) were positive (P > 0.05). In 20 T-NHL patients, 7 cases in plasma cell-free DNA (35%) and 6 cases in biopsy samples (30%) were positive (P >0.05).

CONCLUSIONSTumor-derived DNA could be detected in plasma from underlying cancer patients. For NHL patients, detecting IgH and TCR gamma gene rearrangement in plasma free DNA has the same clinical significance as in biopsy samples.
