Objective To study the effect of cognitive dysfunction of gangliosides on in the treatment of the patients with traumatic brain injury intraoperative and postoperative. Methods From February 2015 to August 2016, 100 patients with cognitive dysfunction after operation were randomly divided into two groups, the control group and the experimental group, 50 cases in each group. The control group were received routine treatment, including medication, brain rehabilitation, and dehydration and intracranial pressure reduction. At this basis, the experimental group were treated with gangliosides. The clinical indexes in the experimental group and the control group were compared and analyzed. Results The cure rate was 90% in the experimental group, and 54% in the control group. The difference in the two groups has statistically significant (P<0.05). Before treatment, there was no significant difference of the MMSE in the two groups. After treatment, the MMSE score in the experimental group was (28.34 ± 4.12) points, and the score of MMSE in the control group was (22.19 ± 5.49) points. The difference in the two groups has statistically significant (P<0.05). Conclusion The effect of cognitive dysfunction is better which ganglioside was used on the treatment of the patients with traumatic brain injury intraoperative and postoperative, and the cure rate is higher. It has the significance of further popularization and application.

Objective: To investigate the relationship between prolactin (PRL) cleavage and the occurrence of hypertension, heart failure (HF) in post-menopausal female patients.
Methods: A total of 216 post-menopausal female subjects were enrolled in our study and they were divided into 3 groups: Hypertension group,n=80 patients with essential hypertension, Hypertension + HF group,n=76 and Control group,n=60 post-menopausal women form regular physical examination. The full length (23 kD PRL), 16 kD PRL fragment, lipid peroxide (LPO), total antioxidant status (TAS), left ventricular ejection fraction (LVEF), NT-proBNP, creatinine, uric acid, fasting blood glucose (FBG) and BMI were examined and compared among different groups.
Results:①There were no real differences in age, creatinine, uric acid, FBG and BMI among groups,P>0.05.②Compared with Control group, Hypertension group had increased LPO and decreased TAS; compared with Control group and Hypertension group, Hypertension + HF group had increased LPO and decreased TAS.③Compared with Control group, Hypertension + HF group showed lower level of 23KD PRL, higher level of 16KD PRL and the higher ratio of 16KD PRL/23KD PRL,P<0.05-0.01.④Pearson correlation analysis indicated that LPO was negatively related to 23KD PRL (r=-0.784,P<0.01), positively related to 16KD PRL (r=0.807, P<0.01); TAS was positively related to 23KD PRL (r=0.768, P<0.01), negatively related to 16KD PRL (r=-0.777P<0.01); 23KD PRL was positively related to LVEF (r=0.852, P<0.01), negatively related to NT-proBNP (r=-0.832P<0.01); 16KD PRL was negatively related to LVEF (r=-0.850,P<0.01), positively related to NT-proBNP (r=0.814,P<0.01).
Conclusion: PRL cleavage was highly related to the occurrence of hypertension and HF in post-menopausal female patients.

Objective To develop a rapid SERS detection method based on monolithic column for detection of dye adul-terated natural indigo .Methods The dyes in natural indigo were extracted and mixed with silver colloid .The spectra were re-corded after applying the mixture solution to the monolithic column since the intertwined pores in monolithic column could con-tribute for the distribution of silver nanoparticles .Results SERS signals of malachite green dyed natural indigo at quantity as low as 500 μg/kg could be obtained .Conclusion This simple ,fast and specific SERS detection method based on monolithic col-umn could be used for rapid detection of stained natural indigo .

Objective To evaluate the clinical performance of chemiluminescent immunoassay (CLIA) on anti-nuclear antibody(ANA) specific autoantibodies testing.Methods A multi-center clinical study A total of 811 Sera samples were collected from 6 collaborating hospitals during the period of April to July 2016, and tested with CLIA and line immunoassay (LIA) in parallel for autoantibodies to ribonucleoprotein(RNP), smith antigen(Sm), SSA/Ro60,SSB/La, centromere protein B(CENPB), double-stranded DNA(dsDNA), nucleosome(Nuc), and ribosome P protein(Rib-P).The positive rate,specificity and qualitative coincidence rate for each antibody between CLIA and LIA methods were analyzed.All discrepant samples for systemic lupus erythematosus (SLE) highly specific autoantibodies (including anti-Sm, dsDNA, Nuc and Rib-P) were retested by enzyme linked immunosorbent assay (ELISA) and further analyzed with SLE disease cohort using McNemar test.Results The positive rate and specificity of CLIA and LIA for antibodies to ANA specific antigens were comparable.Excellent qualitative coincidence were found between CLIA and LIA for the detection of anti-RNP, SSA/Ro60, SSB/La and CENPB (Kappa>0.75), while the coincidence rate foranti-Sm, dsDNA, Nuc and Rib-P detection were moderate (0.4

ObjectiveTo observe the lower limb muscle activation strategy of healthy middle-aged and old women during stair ascent and descent with surface electromyography. MethodsFrom August, 2021 to February, 2022, 20 healthy middle-aged and old women were measured the surface electromyography root mean square (RMS) and integrated electromyography (iEMG) of bilateral vastus lateral, rectus femoris, vastus medialis, biceps femoris and semitendinosus during stair ascent and descent, and co-contraction ratio was calculated. ResultsDuring stair ascent, the RMS of bilateral vastus lateral, rectus femoris and vastus medialis was higher at starting stage than at following stage (|t| > 6.650, P < 0.001), while the RMS of biceps femoris and semitendinosus was lower (t > 3.559, P < 0.01); and the co-contraction ratio of hamstrings/quadriceps was lower at starting stage than at following stage (t > 8.185, P < 0.001). During stair descent, the RMS of bilateral vastus lateral, vastus medialis, biceps femoris and semitendinosus was higher at following stage than at starting stage (t > 2.345, P < 0.05), as well as the co-contraction ratio of hamstrings/quadriceps (t > 2.405, P < 0.05). ConclusionThe activities of the muscles around the knees are almost symmetrical during stair ascent and descent for healthy middle-aged and old women. The activation and co-contraction ratio of quadriceps and hamstring are various at starting/following stages.
