The present study aimed to investigate the effect and the mechanisms of Bu-zhong-yi-qi-tang (BZYQ) on Spleen-Qi deficiency rat's model using nuclear magnetic resonance (NMR) metabolomics and multivariate statistical analysis methods. The rat Spleen-Qi deficiency model was established as follows: oral administration of Radix Rhei extract, loaded swimming and starvation for 24 h. The body weight and motor behavior of the rats were measured and recorded once a week. BZYQ could significantly improve body weight and behavioral of Spleen-Qi deficiency model rats compared with the model group (P < 0.05, 0.01). After drug administration, the changes in the levels of endogenous metabolites in the spleen including decreasing lactate, taurine and hypoxanthine, increasing glutamate and scyllo-inositol compared with the model group. The metabolomics approach is an effective tool for the investigation of the pharmacologic mechanism of BZYQ and it is helpful to further research.

OBJECTIVETo observe the effect of Bushen Wenyang Huayu Recipe (BWHR) on hypoxia inducible factor-1α (HIF-1α), proline hydroxylase2 (PHD2), von Hippel Lindau disease (VHL) suppressor gene expressions in endometriosis (EM) rats with Shen yang deficiency blood stasis syndrome (SYDBSS), and to explore the pathogenesis of EM and the mechanism of BWHR for treating EM.

METHODSTotally 50 SD rats were randomly divided into five groups, i.e., the blank control group, the sham-operation group, the model group, the Chinese medicine (CM) group, and the Western medicine (WM) group, 10 in each group. Rats in the blank control group and the sham-operation group were fed routinely. Rats in the rest 3 groups received 30-day "extended refrigerator freezing and ice water immersion" and combined with " autotransplantation" to establish EM rat model with SYDBSS. One Milliliter BWHR at 3.33 g/mL was administered to rats in the CM group by gastrogavage. Gestrinone at the daily dose of 0. 5 mg/kg was administered to rats in the WM group by gastrogavage. Equal volume of normal saline was administered to rats in the model group, the blank control group, and the sham-operation group. The size and morphology of ectopic foci in rats were observed after 4 weeks of medication. Expressions of serum CA125, plasma cyclic adenosine monophosphate (cAMP), and plasma cyclic guanosine monophosphate (cGMP) were detected by radioimmunoassay. Morphological changes of eutopic endometrium and ectopic tissue were observed under the optical microscope by HE staining. Protein expressions and contents of HIF-lα, PHD2, and VHL were detected by immunohistochemical SABC method and Western blot. mRNA expressions of HIF-1α, PHD2, and VHL were detected by RT-PCR.

RESULTSThe ectopic foci grew significantly in the model group. Their volumes were obviously contracted after treated by CM and WM. Compared with the blank control group and the sham-operation group, serum CA125 and plasma cGMP obviously increased, cAMP obviously decreased (P < 0.05); expressions and contents of HIF-1α mRNA and protein all decreased (P < 0.05); mRNA and protein expressions and contents of PHD2 and VHL all decreased in the model group (P < 0.05). Compared with model group, levels of CA125 and cGMP obviously decreased; cAMP levels obviously increased, expressions and contents of HIF-1α mRNA and protein all increased, mRNA and protein expressions and contents of PHD2 and VHL all increased in the WM group and the CM group (P < 0.05). Compared with the CM group, PHD2 protein contents were higher in the WM group (P < 0.05). HIF-1α was negatively correlated with PHD2 (r = -0.799, P = 0.00). HIF-1α was negatively correlated with VHL (r = -0. 625, P = 0.003).

CONCLUSIONSBWHR could effectively treat EM. Its mechanism might be associated with reducing contents of HIF-1α, serum CA125, and plasma cGMP, and up-regulating expressions of PHD2, VHL, and cAMP.

Objective To explore the effects of forepaw sensorimotor deprivation in early life on hippocampus-dependent spatial reference learning and memory in rats. Methods Newborn SD rats were randomly assigned to experiment group (deprivation of forepaw sensorimotor function, n=53) and control group(n=55). Rats of postnatal day 13 (PN13) in experiment group were seleeted, and models of forepaw sensorimotor deprivation were established by microsurgical technique. Open field tests and Morris water maze tests were performed during the time periods of PN25(PN21-31), PN35 (PN31-39), PN45(PN41-50) and PN60(PN56-64) to evaluate the locomotor activity and spatial reference learning and memory, respectively. Results In open field tests, there was no significant difference in parameters of locomotor activity and exploratory behavior between the two groups (P>0.05). In Morris water maze tests, eontrol group performed significantly better than experiment group during training sessions and probe tests on PN25 and PN35 (P<0.05). While on PN45, although there was no significant difference between the two groups during training sessions, control group performed significantly better than experiment group during probe tests (P<0.05). Conclusion The deprivation of forepaw sensorimotor in early life has no signifieant effect on the locomotor activity and exploratory behavior of rats, but can impair the spatial reference learning and memory.

Objective: To observe the efficacy of long-retaining scalp acupuncture plus interactive training in improving upper- extremity dysfunction in cerebral stroke patients. Methods: Ninety-five patients with upper-extremity dysfunction after cerebral stroke were randomized into two groups, with 48 cases in the treatment group and 47 cases in the control group. Conventional internal medicine treatment was offered to both groups. In both groups, Anterior Oblique Line of Vertex-temporal (MS 6, the middle 2/5) and Posterior Oblique Line of Vertex-temporal (MS 7, the middle 2/5) were selected from the same side of the brain lesion (the side apposing to the hemiplegic limb) for scalp acupuncture treatment. In the treatment group, the scalp acupuncture needles were retained for 7 h, in combination with interactive training, while the needles were also retained for 7 h in the control group but without interactive training. Prior to treatment and at 2-week and 4-week treatment, the two groups were scored using the functional test for the hemiplegic upper extremity-Hong Kong (FTHUE-HK) and simplified Fugl-Meyer assessment-upper extremity (FMA-UE). Results: The total effective rate was 97.9％ in the treatment group, higher than 74.5％ in the control group (P<0.01). The FTHUE-HK score was higher at 2-week and 4-week treatment than before treatment in both groups, presenting statistically significant intra-group differences (all P<0.001); the FTHUE-HK score was higher at 4-week treatment than at 2-week treatment in both groups, presenting statistically significant intra-group differences (both P<0.001). At 2-week and 4-week treatment, the FTHUE-HK score was higher in the treatment group than in the control group, showing significant between-group differences (both P<0.05). During the whole treatment process, the treatment group had higher FTHUE-HK scores compared with the control group, but there was no statistical significance comparing the change of the score between the two groups at 2-week treatment (P>0.05), while the between-group difference in the change of the score was statistically significant at 4-week treatment (P<0.05). The FMA-UE score was higher at 2-week and 4-weeks treatment than before treatment in both groups, presenting statistically significant intra-group differences (all P<0.001); the FMA-UE score was higher at 4-week treatment than at 2-week treatment in both groups, presenting statistically significant intra-group differences (both P<0.001). At 2-week and 4-week treatment, the FMA-UE was higher in the treatment group than in the control group, and the between-group differences were statistically significant (both P<0.01). The FMA-UE score rose gradually with the increase of treatment session, and there was statistical significance comparing the change of the score between the two groups at 2-week and 4-week treatment, respectively (both P<0.05). Conclusion: Long-retaining scalp acupuncture plus interactive training results in more significant efficacy than long-retaining scalp acupuncture alone in improving the upper-limb dysfunction after cerebral stroke and the advantage becomes more notable after 2-week consecutive treatment.

Objective To investigate the effect of fibreoptic endoscopic evaluation of swallowing (FEES) in the assessment of dysphagia. Methods Fifty - two patients with neurogenic dysphagia underwent FEES and videofluoroscopy (VF) within a 2 - day period. The results obtained were compared. Results FEES with all consistencies revealed premature leakage in 48.1%, pooling in 75.0%, penetration in 69.2%, and aspiration in 55.8%, silent aspiration in 28.8% of patients. VF revealed above items in 44.2%, 63.5%, 57.7%, 46.2% , 21.2%, respectively. The FEES was then measured against the VF for sensitivity, specificity, positive predictive value, and negative predictive value. FEES showed higher sensibitity and negative coincidence rate of penetration(90.0%, 81.3%) ,aspiration(87.5% ,87.0%) and silent aspiration(90.9%, 97.3%). According to the severity, the dysphagia in patients was classified into no penetration, penetration, aspiration and silent aspiration. A weighted Kappa value of 0.713 signified "substantial" agreement between the two tests. Conclusions FEES is an effective and valuable tool for evaluating oropharyngeal dysphagia,and is helpful in guiding the patients for diet and rehabilitation.
