[Effect of Astragali Radix with different sulfur fumigation technologies on immune function in mice].

To investigate the effect of Astragali Radix with different sulfur fumigation technologies on immune function in mice, and observe the effect of different Astragali Radix samples on carbon clearance in cyclophosphamide induced immunosuppressed mice, on immune organ weight in immunosuppressed mice and on delayed type hypersensitivity response (DTH) induced by 2,4 dinitrochlorobenzene. Carbon clearance index, phagocytic index, organ index and ear swelling rate were taken as the indexes. The results showed that, all of the Astragali Radix with different sulfur fumigation technologies markedly increased the carbon clearance index K, phagocytic index α, immune organ weight and improved the ability of DTH response in immunosuppressed mice.

[Analysis of lignans and their metabolites derived from Schisandra chinensis and vinegar Schisandra chinensis in rats’ plasma, bile, urine and faeces based on UHPLC-QTOF/MS].

UHPLC-QTOF/MS technique was used to study the differences of lignans and their metabolites derived from Schisandra chinensis and vinegar Schisandra chinensis in rat plasma, bile, urine and faeces by the data processing techniques such as the dynamic background subtract(DBS), mass defect filtering(MDF) and enhance peak list (EPL) in analysis. In order to enhance accuracy for Schisandra chinensis hepatoprotective effect, we established rat acute alcoholic liver injury model in this experiment, and studied the prototype components and metabolisms of Schisandra lignans in vivo under pathological condition. The main ingredients of alcohol extract are lignans, including deoxyschizandrin, schisandrin B, schizandrin C, schizandrol, schizandrol B,schisantherin, schisantherin B, schisanhenol, gomisin G, gomisin J.

[Effects of electroacupuncture on pain reactions, expression of spinal kappa-opioid receptor and contents of enkephalin and beta-endorphin in periaqueductal gray of midbrain in dysmenorrhea model rats].

Objective: To observe effects of electroacupuncture (EA) on the expression of kappa-opioid receptor in the dorsal horn of the spinal cord and contents of enkephalin(ENK) and beta-endorphin (beta-EP) in the periaqueductal gray (PAG) of midbrain in dysmenorrheal rats, so as to reveal its underlying mechanism in relieving dysmenorrhea.

Methods: A total of 80 female SD rats were randomized into saline control (control), model, Sanyinjiao (SP 6), Xuanzhong (GB 39), non-acupoint groups (16 rats/group). Dysmenorrhea model was established by subcutaneous injection of estradiol benzoate (0.

[Effects of instant electroacupuncture at the different acupoints on IP3 in the uterus tissue of dysmenorrhea model rats].

Objective: To compare the effects of instant electroacupuncture (EA) at the different acupoints on IP3 in the uterus tissue of dysmenorrhea model rats so as to investigate the specificity of acupoints.

Methods: Fifty female SD rats were randomly divided into a saline group, a model group, a Sanyinjiao (SF 6) group, a Xuehai (SP 10) group and a Hegu (LI 4) group, 10 rats in each group. The rats were given subcutaneous injection of Estradiol Beozoate injection for 10 consecutive days except those in the saline group, and intraperitoneal injection of 2U Oxytocin at 1 h after the last administration to create the dysmenorrhea rats model, and the saline group was given the same dose of saline every day.

[Effects of electroacupuncture of "Sanyinjiao" (SP 6) on contents of MDA and beta-EP, and expression of HSP 70 in the uterus in rats with dysmenorrhea].

Objective: To investigate the effect of electroacupuncture (EA) of "Sanyinjiao" (SP 6) on the uterus in dysmenorrhea rats so as to study its underlying analgesic mechanism.

Methods: A total of 48 SD rats during diestrus were randomized into normal saline (control) group, model group and acupuncture group according to a random number table, with 16 rats in each group. Dysmenorrhea model was established by subcutaneous injection of Estradiol benzoate (0.

[Neural apoptosis and apoptosis-related genes in intracerebral hemorrhage patients].

Objective: To observe the neural apoptosis and expression of apoptosis-related genes in brain in order to elucidate the regulation mechanism in the perihematomal region of intracerebral hemorrhage (ICH) patients.

Methods: Specimens of perihematomal region in human brain were obtained from 29 patients undergoing surgical evacuation of an intracerebral hematoma. Specimens of brain tissue were collected from the corpses of 6 persons within 3 hours after the accidental death.
