ObjectiveTo observe the effect of transcutaneous acupoint electrical stimulation (TAES) on the ovariangranulosa cell apoptosis-related proteins, Bcl-2 and Bax, as well as the oocyte quality in theolder women with kidney deficiency receiving in vitro fertilization-embryo transfer (IVF-ET).MethodSixty-six older women with kidney deficiency who were receiving IVF-ET because of the fallopian tube factor were randomized into a treatment group (intervened by TAES) and a control group (intervened by sham acupuncture), 33 in each group. The kidney-deficiency syndrome score, HCG E2/follicle count per day, excellent follicle rate, excellent embryo rate, and clinical pregnancy rate were observed and compared between the two groups; Western blot was used to detect the expression of protein Bcl-2 and Bax.ResultCompared to the control group, the treatment group had significant improvement in kidney-deficiencysymptoms (P<0.01), significant increases in theHCG E2/follicle count per day, excellent follicle rate, and excellent embryo rate (P<0.05), enhanced expression of Bcl-2 protein (P<0.01), and decreased expression of Bax protein (P<0.01); while there were no significant differences in comparing theretrievedoocyte number and clinical pregnancy rate (P>0.05). The expression of Bcl-2 and Bax proteins were markedlycorrelatedwith IVF-related indexes (P<0.05).ConclusionTAES can improve the kidney-deficiency symptoms and the quality of oocyte and embryo inolder women; this action is possibly related to the regulation of expression of the cell apoptosis-related protein Bcl-2 and Bax, as well as the decrease ofgranulosecell apoptosis.

Objective To investigate the effect of Ginkgo biloba extract on serum divalent metal transporter1 ( DMT1 ) , glucose regulated protein 75(grp75) and nerve function in patients with Parkinson disease.Methods 38 cases of patients loith parkinson disease according to different drugs were divided into experimental group and control group, 19 cases in each group.Control group was treated with levodopa and Benserazide tablet, experimental group on the basis of control group, was given Ginkgo biloba extract tablets, treatment for 4 weeks.After treatment, DMT1, grp75 and cognitive function of all patients in substantia nigra were detected.ResuIts Compared with before treatment, two groups of patients with lower DMT1 level (P<0.05), compared with control group, experimental group of patients with lower DMT1 levels (P<0.05).Compared with pre-treatment, two groups of patients grp75 level was higher (P<0.05), compared with control group, experimental group after treatment grp75 level was higher (P<0.05).Compared with before treatment, the two groups of patients with MoCA scores were higher (P<0.05), HAMD scores were lower (P<0.05).Compared with control group, experimental group after treatment MoCA scores were higher (P<0.05), HAMD scores were lower (P<0.05).ConcIusion Ginkgo biloba extract can significantly reduce the level of DMT1 in the substantia nigra of Parkinson patients, increase the level of grp75, and improve the cognitive function.

Objective To establish a simple, cost-effective method to measure reactive oxygen metabolites ( ROMs) using automatic biochemical analyzer.Methods Serum samples were collected from 50 healthy individuals and 50 hospitalized patientsin Beijing Hospital from September 2013 to November 2013.By setting up and optimizing parameters on automatic biochemical analyzer, a new method of measuring ROMS was established with TBHP as calibrator.130 healthy non-smokers were recruited in Beijing Hospital from November 2013 to December 2013 to establish reference interval, including 73 males and 57 females.The average age was 68.8 ±12.5.According to CLSI documents, there was the establishment of the new method including precision, limit of blank ( LoB ) , limit of detection ( LoD ) , limit of quantitation (LoQ), linearity,interference testing, and reference interval.Results The intra assay imprecision was 1. 5%-4.1% and the total imprecision was 4.4%-9.9%.LoB was 0.85 mmol/L TBHP;LoD was 2. 7mmol/L TBHP;LoQ was 5.9mmol/L TBHP.The linearity was 5.9-600 mmol/L (R2 =0.995).When triglyceride≤28.58 mmol/L, hemoglobin≤173 g/L, vitamin C≤60 mg/dl and bilirubin≤73.8 μmol/L, the deviation was -7.6%, 4.6%, -98.9%, 19.1%respectively.The normal reference interval was 61.9 -88.1 mmol/L TBHP.Conclusions The newly-established method has good performances of precision,LOD and linearity, which can meet the clinical needs.The interference of triglyceride and hemoglobin is small, while vitamin C and bilirubin have stronger interference on measurement.( Chin J Lab Med,2015,38:163-167)

Objective To study the expression of urokinase-type plasminogen activator (uPA) and its relation with expression of receptor (urokinase-type plasminogen activator receptor uPAR) in epithelial ovari- an cancer (OEC) and with the clinic prognosis.Methods Expression of uPA and uPAR protein was detected by Streptavidin-biotin-HRP in 68 cases of epithelial ovarian cancer and compared with that in 10 cases of borderline tumor,10 cases of benign tumor and 10 cases of normal tissue,and correlation between them was analyzed.The different expression groups of uPA was correlated with the prognosis of ovarian epithelial can- cer.The expression of uPA showed a correlation with short survival time (P

OBJECTIVETo explore the performance patterns of reaction point Jingtong in balance acupuncture through multi-center and big-sample clinical investigation. Methods The Jingtong points of balance acupuncture on healthy side and affected side were observed among 230 cases of cervical spondylosis and scores of self-discomfort in reaction point, color of skin, changes of skin, morphology of subcutaneous tissue and abnormal pressing pain were recorded. The software SPSS 15.0 was applied to statistically analyze the recorded scores.

RESULTSAmong 230 cases, the reaction point appeared in 226 cases, accounting for 98. 3%. Among the 226 cases who had reaction point, the total score of symptom and sign was (1.08+/-1.09) on the healthy side and (0. 84+/-1. 36) on the affected side, which had statistical significance (P<0. 01); score of self-discomfort in reaction point was (0. 76 +/-0. 83) on the healthy side and (0. 40+/-0.80) on the affected side, which had statistical significance (P<0.01); the score of skin color was (0.10+/-0.36) on the healthy side and (0. 03+/- 0. 19) on the affected side, which had statistical significance (P<0. 05); the score of abnormal pressing pain was (2. 47+/-2. 46) on the healthy side and (1. 39+/-2. 37) on the affected side, which had statistical significance (P<0. 01).

CONCLUSIONThe total score of symptom and sign of reaction point Jingtong on the healthy side is higher than that on the affected side, indicating positive reaction of Jingtong on the healthy side has specificity for cervical spondylosis. When patient has cervical spondylosis on either side of neck, the other side will have anomaly in Jingtong.
