Objective To explore the changes of GRO-α and VEGF in the peritoneal fluid of women with endometriosis and their correlation. Methods The levels of GRO-α and VEGF were detected by enzyme linked immunosorbent assay ( ELISA ) method in 39 cases of endometriosis and 25 normal cases of without endometriosis. Results The levels of GRO-αand VEGF in the peritoneal fluid of EMs group were ( 108.77 ± 20. 58 ) pg/ml and ( 199. 67 ± 99. 26 ) pg/ml separately, and it was significantly higher than those in control group ( 71.07 ± 18. 96 ) pg/ml, ( 115.46 ± 32. 39 ) pg/ml. The differences were statically significant( P <0. 05). The level of GRO-α in the peritoneal fluid of the patients in stage Ⅰ and Ⅱ was sig-nificantly lower than that in stage Ⅲ and Ⅳ[(99.43 ± 16.05)pg/ml vs (117.65 ± 20.8)pg/ml, P <0. 05] , while the level of VEGF in the peritoneal fluid of the patients in stage Ⅰ and Ⅱ was significantly higher than that in stage Ⅲ and Ⅳ[(246. 89 ± 114. 34) pg/ml vs ( 152. 82 ± 54. 55 ) pg/ml, P < 0. 05] .There was positive correlation between the level of GRO-α and r-AFS ( r = 0. 439, P < 0. 05 ), but no cor-relation between the level of VEGF and r-AFS ( r = -0. 210, P >0.05). There was no correlation be-tween peritoneal fluid levels of GRO-α and VEGF in the EMs group ( r =-0. 05, P>0. 05). Conclusion Compared with control group, the levels of GRO-α and VEGF in peritoneal fluid of women with endome-triosis were significantly increased, which indicated that the increased GR0-α and VEGF secretion involved in the pathogenesis of this disease. There was correlation between the peritoneal fluid level of GRO-α and the degree of EMs.

Objective To investigate the therapeutic effect of acupuncture combined with Vitalstim electric stimulation therapy for treatment of patients with dysphagia after ischemic stroke.Methods Ninety-two patients with dysphagia after ischemic stroke in accord with the criteria of enrollment in this study were admitted to the Department of Acupuncture of the First Affiliated Hospital of Tianjin Traditional Chinese Medicine University from May 2014 to November 2016, and they were divided into a control group and an observation group by random number table, 46 cases in each group. Both groups were treated with stroke conventional drug therapy and feeding swallowing rehabilitation training, in addition, Vitalstim swallowing therapeutic electrical stimulation therapy was used in the control group, and acupuncture combined with Vitalstim stimulation were applied in observation group. The changes of swallowing ability score, video fluoroscopic swallowing study (VFSS) score and adverse reactions were observed before and after treatment in the two groups, and the curative effect of combined method was evaluated.Results Compared with those before treatment, the swallowing ability and VFSS score of two groups after treatment were obviously higher, and the degrees of changesin observation group were more significant than those in control group (swallowing score: 8.12±1.13 vs. 7.45±1.04, VFSS score: 7.97±1.05 vs. 5.67±0.88, allP < 0.05); the total efficiency in the observation group was markedly higher than that in the control group [95.7% (44/46) vs. 78.3%(36/46)], the adverse reactions (wrong aspiration, pulmonary infection) in the observation group were significantly lower than those in the control group [10.9% (5/46) vs. 28.3% (13/46)], and there were statistically significant differences between the two groups (bothP < 0.05).Conclusions Acupuncture combined with Vitalstim electric stimulation therapy can improve the swallowing ability in patients with dysphagia after ischemic stroke, and the therapy has less adverse reactions; compared with the simple Vitalstim electric stimulation therapy, in the aspect of improving swallowing ability, the therapeutic effect of combined therapy is more significant.

Objective To analyze the clinical data of selective uterine arterial embolization in treating uterine leiomyoma retrospectively. Methods Super-selective arterial embolization were performed using Seldinger's technique. The degree of shrinkage of uterine and leiomyoma were measured, and the influence of the treatment on ovarian function was analysed as well. Results After embolization, uterine and leiomyoma significantly shrinked. Uterine leiomyoma artery embolization(UAE) had no influence on ovarian function. Conclusions UAE is an effective method in treating uterine leiomyoma.

Using different models of focal cerebral ischemia, the temporal and spatial rules of metabolism and energy changes in the post-ischemia brain tissue were measured by proton magnetic resonance spectroscopy (1HMRS) to provide valuable information for judging the prognosis of acute focal cerebral ischemia and carrying out effective therapy. Nine healthy Sprague-Dawly rats (both sexes) were randomly divided into two groups: The rats in the group A (n = 4) were occluded with self-thrombus for 1 h; The rats in the group B (n = 5) were occluded with thread-emboli for 1 h. The 1H MRS at 30, 40, 50, 60 min respectively was examined and the metabolic changes of NAA, Cho and Lac in the regions of interest were semiquantitatively analyzed. The spectrum integral calculus area ratio of NAA, Cho, Lac to Pcr + Cr was set as the criterion. The values of NAA.Cho in the regions of interest were declined gradually within 1 h after ischemia, especially, the ratio of Cho/(Pcr + Cr), NAA/(Pcr + Cr) at 60 min had significant difference with that at 50 min (P < 0.05). The ratio of Lac/(Pcr + Cr) began to decrease at 40 min from initial increase of Lac in both A and B groups. MR proton spectrum analysis was a non-invasive, direct and comprehensive tool for the study of cellular metabolism and the status of the biochemical energy in acute ischemia stroke.

BACKGROUND: Presently, it is a certain preventive effect of local emplacement of various isolated materials during operation and postoperatively drug-controlled inflammatory reaction on adhesion between epidural and nerve root after laminectomy.OBJECTIVE: To study the preventive effect of chitosan and titanium net on epidural cicatricle adhesion after laminectomy.DESIGN, TIME AND SETTING: Randomized controlled animal study, which was performed in Guiyang Medical College from June to December 2005.MATERIALS: Eighty adult rabbits, weighing (2.0±0.2) kg, were used to establish vertebral plate resection models. Chitosan was provided by Shanghai Qisheng Biological Agent Industry Company, and titanium net by Guizhou Kelun Pharmacology Company Limited.METHODS: Eighty adult rabbits were randomly divided into four groups, including control group (0.5 mL saline), titanium net group (titanium net in the size of 1.0 cm × 0.8 cm was covered on defect region of vertebral plate and fixed on processus spinosus of upper and lower cone, bilateral muscles and soft tissues), chitosan group (2 mL chitosan), and chitosan + titanium net group (combination of chitosan and titanium net). Six rabbits were sacrificed in the 2nd and 4th weeks postoperatively, and eight rabbits were chosen as the samples in the 8th week.MAIN OUTCOME MEASURES: Morphological changes of cicatricle.RESULTS: Cicatricle was clearer in the control group. Titanium net could relieve peripheral cicatricle of dura mater and effectively isolate peripheral cicatricial tissue and spinal dura meter. Chitosan could remarkably prevent from cicatricle adhesion and inhibit inflammatory reaction. The combination of chitosan and titanium net could effectively inhibit proliferation of cicatricle surrounding dura meter.CONCLUSION: Association of chitosan and titanium net can effectively inhibit cicatricle adhesion surrounding dura meter after laminectomy.

Objective To investigate the effects of long term exposure of 18F-FDG-PET/CT X-rays on rabbit immune system.Methods The rabbits were irradiated with 18F-FDG-PET/CT every day and this irradiation treatment continued for 3 months.At each month,the total number of white blood cells,thymus index and spleen index,phagocytic index,immune globulins,TNF-α and IL-1 in peripheral blood and serum were detected.Results After long-term 18F-FDG-PET/CT irradiation,the total number of white blood cells increased,the thymus and spleen index decreased (t =3.144-72.903,P ＜ 0.05),the phagocytic index and phagocytic percentage decreased after 1 or 2 months(t =2.719-11.859,P ＜ 0.05),and the number of immune cells marked with CD4 + increased but CD8 + decreased(t =6.433-29.877,P ＜ 0.05).In addition,the level of immune globulin in the serum decreased,but the expressions of TNF-α and IL-1β increased (t =2.720-28.775,P ＜ 0.05).Conclusions 18F-FDG-PET/CT has some damage effects on the immune system of male Japanese big ear rabbit,suggesting that the negative effects of PET-CT should be paid close attention to during clinical application.
