Characteristics of Tremor in Young or Late Onset Parkinson's Disease / 中国康复理论与实践

Objective To compare the characteristics of tremor and improvement after acute levodopa challenge test in young onset Parkinson's disease(YOPD)and late onset Parkinson's disease(LOPD)with a cross-sectional study. Methods From Match to September,2017,70 Parkinson's disease inpatients with rest or postural tremor in at least one extremity were included,in which 23 patients were in YOPD group,and other 47 in LOPD group according to their ages of onset.They finished acute levodopa challenge test and were analyzed for dominant tremor frequen-cy,amplitude and rhythm under resting state,posturing and holding 1000 grams state,respectively. Results YOPD group was younger(t=-2.423,P<0.01)with lower Hoehn-Yahr stage(χ2=-4.604,P<0.05),and needed less equivalent dose of levodopa at early stage(first five years)(t=-2.119,P<0.05).There was a bigger ratio of patients with rest tremor in frequency of four to six Hz in YOPD group than in LOPD group(χ2=3.896,P<0.05). Rigidity and bradykinesia scores of LOPD group positively correlated with the course of disease (r=0.34, P<0.05),while it was not found in YOPD group. Conclusion Tremor expresses most in the classical way in YOPD patients,and tremor analysis could help to diagnose young adults. Both YOPD and LOPD patients get well in acute levodopa challenge test, while YOPD patients need less equivalent dose of levodopa at early stage.

Treatment of premature ovarian failure by bushen huoxue recipe combined estrogen and progesterone: a clinical research / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To observe the clinical efficacy of bushen huoxue recipe (BHR) combined estrogen and progesterone in treating premature ovarian failure (POF), and to explore an effective treatment program of POF by integrative medicine.</p><p><b>METHODS</b>Totally 265 POF patients were randomly assigned to 3 groups, i.e., Group I (86 cases, treated by BHR),Group II (88 cases,treated by conjugated estrogens and medroxyprogesterone acetate), and Group III (91 cases,treated by BHR +conjugated estrogens and medroxyprogesterone acetate). The therapeutic course for each group was 6 months. The main symptoms (including menstrual cycle, hectic fever, night sweat, vaginal dryness, and low libido), laboratory indices [including follicle stimulating hormone (FSH), luteotropic hormone (LH), estradiol (E2), and inhibin B (INH-B)], B-ultrasound indicators (including endometrial thickness, ovarian volume, and antral follicle count), and adverse reactions were observed in the three groups at the end of treatment and 6 months after treatment.</p><p><b>RESULTS</b>Compared with before treatment, the main symptoms, laboratory indices, and B-ultrasound indicators were statistically improved in the three groups at the end of treatment and 6 months after treatment (P <0.05, P <0.01). Better effects were obtained in Group III in improving symptoms of the menstrual cycle, vaginal dryness, and low libido, lowering levels of FSH and LH, elevating levels of E2and INH-B, and ameliorating the endometrial thickness, the ovarian volume, and the antral follicle count (P <0.05, P <0.01). No obvious adverse reaction occurred in the three groups.</p><p><b>CONCLUSION</b>BHR combined estrogen and progesterone showed better clinical efficacy than use of BHR or estrogen/progesterone alone, indicating it was an effective treatment program for POF.</p>

Study on effects of acupuncture on mice dysmenorrhea model and the mechanism / 中国针灸

<p><b>OBJECTIVE</b>To probe the mechanism of acupuncture in treatment of dysmenorrhea.</p><p><b>METHODS</b>Adult mice with no pregnancy were randomly divided into a normal group, a model group, an acupuncture group and a medication group. The model group, the acupuncture group and the medication group were modeled by Diethylstilbestrol and Ocytocin. For the acupuncture group, at the 7th day of modeling, acupuncture was given at "Sanyinjiao" (SP 6), "Diji" (SP 8), once a day, for 5 days; and at the 7th day of modeling, Yimucao Gao 0.6 mg/g was given intragastrically to the medication group for 5 days. The stretching latent period and the number of stretching within 30 min were observed, and mRNA levels of ocytocin receptor (OctR) and vasopressin receptor (VasR) in the uterus tissue were detected with RT-PCR method.</p><p><b>RESULTS</b>Compared with the model group, the stretching latent period extended (P < 0.05) and the number of stretching within 30 min significantly decreased (P < 0.05); and there were significant differences in the mRNA levels of ocytocin receptor and vasopressin receptor in the uterus tissue in the model group as compared with those in other 3 groups (P < 0.05, P < 0.01).</p><p><b>CONCLUSION</b>Acupuncture can improve the dysmenorrheal symptom to a certain extent, and the mechanism is possibly related to regulative effects of acupuncture on hormones-mediating receptors in mice.</p>

Study on fingerprints of Citrus aurantium from different places by capillary electrophoresis / 中国中药杂志

<p><b>OBJECTIVE</b>To develop a high performance capillary electrophoresis method for Citrus aurantium fingerprints to control its quality.</p><p><b>METHOD</b>The background electrolyte (BGE) was an 80 mmol x L(-1) boric acid solution containing 15 mmol x L(-1) borate. The pH of the BGE was adjusted to 9.70 with KOH solution. The detection wavelength was 201 nm and a voltage of 16 kV was applied. The sample hydrodynamic injection was 0.4 ps with a duration time of 8 sec. C. aurantium was extracted by water and a set of capillary electrophoresis fingerprints (CEFP) containing 12 co-possessing peaks was obtained.</p><p><b>RESULT</b>There were good similarities between the standard CEFP and each set of CEFP of C. aurantium collected from eleven different places, and their similarity coefficients were between 0.973 and 0.996.</p><p><b>CONCLUSION</b>The CEFP has acceptable precision, reproducibility and stability and can be used for the quality control of C. aurantium.</p>
