Objective To investigate the clinical efficacy of fluoroscopy-guided intestinal adhesion lysis, as a new non-surgical method, in treating incomplete adhesive small intestinal obstruction in order to improve the therapeutic results of adhesive intestinal obstruction. Methods A total of 93 patients with incomplete adhesive small intestinal obstruction were enrolled in this study. The patients were divided into study group (n=49) and control group (n=44). Fluoroscopy-guided intestinal adhesion lysis together with restoration of inter-intestinal loop enterocele was carried out for the patients of the study group , while traditional conservative surgical therapy was employed for the patients of the control group. The study group was comparable with the control group in patients’ age, gender, medical history, disease course, X-ray findings, etc. Results Of the 49 cases in the study group, complete cure was obtained in 40 with a cure rate of 81.6%. The mean hospitalization day was 0.3 day, and the average operation time was 3.25 hours. Among the 44 patients in the control group, complete cure was obtained in 37 with a cure rate of 84.1%. The mean hospitalization day was 7.6 days, and the average therapeutic time was 183.26 hours. Conclusion For the treatment of incomplete adhesive small intestinal obstruction , the therapeutic efficacy of fluoroscopy-guided intestinal adhesion lysis together with restoration of inter-intestinal loop enterocele is better than that of traditional conservative surgical therapy.

Objective The purpose of this investigation was to investigate the neuroprotective effects of rhubarb for ICH,as well as its mechanism.Methods ICH was produced in adult Spargue-Dawley rats by injection of collagenase IV(0.05U/0.5uL).Intraperitoneal injection of rhubarb (70mg/kg) or saline,was started at 3,6 or 12 hours post-ICH respectivdy.Casepase-3 activity.TUNEL and neurological behavior function were performed 24hours after ICH.Results Rhubarb siven at 3 or 6 hours can inhibit casepase-3 activity(P<0.001),reduce TUNEL positive cells(P<0.05) and attenuate apomorphine-induced rotation(P<0.05) at 24 hours after ICH.However,the animals which were treated 12 hours showed no improvement.Conclusion Rhubarb may be a potential drug for ICH patients for its possible effect of inhibiting apoptosis.

Objective:To observe the clinical efficacy of Ba-pulling and Qian-traction manipulation with neck suspension and movement for acute cervical radiculopathy. Methods: A total of 85 patients who met the inclusion criteria were randomized into an observation group and a control group by random numbers, with 43 cases in the observation group and 42 cases in the control group. The observation group was treated with Ba-pulling and Qian-traction manipulation with neck suspension and movement;while the control group was treated with Bashen-pulling and stretching manipulation in a supine position. The treatment was performed once a day, 10 times as a treatment course. The therapeutic efficacy was evaluated after 1 treatment course, and the changes in the scores of visual analog scale (VAS) and neck disability index (NDI) were observed. Results: The total effective rate was 97.7% in the observation group, and 83.3% in the control group, and the difference between the two groups was statistically significant (P＜0.05). After treatment, the VAS and NDI scores of both groups were significantly decreased (both P＜0.01), and the differences in the VAS and NDI scores between the two groups were statistically significant (both P＜0.01). Conclusion: Both Ba-pulling and Qian-traction manipulation with neck suspension and movement and Bashen-pulling and stretching manipulation in a supine position can relieve pain and improve cervical function in patients with acute cervical radiculopathy, and Ba-pulling and Qian-traction manipulation with neck suspension and movement can produce more significant efficacy than Bashen-pulling and stretching manipulation in a supine position.

To investigate the protective effect of preconditioning with hyperoside ( Hyp) against myocardial ischemia-reperfusion injury (MIRI) in rats and the role of PI3K/Akt signaling pathway. MIRI was established by ligation of left anterior descending coronary artery for 30 min followed by reperfusion for 120 min in rats. Male SD rats were randomly divided into five groups: sham group,model group (MIRI),Hyp preconditioning group(Hyp), Hyp preconditioning + LY294002 (a PI3K/Akt signaling pathway inhibitor) group (Hyp + LY), and LY294002 group (LY). At the end of reperfusion, hemodynamic parameters were recorded as left ventricular systolic pressure (LVSP) , left ventricular end-diastolic pressure ( LVEDP) and maximal rate of increase and decrease of left ventricular pressure (± dP/dt(max)). Myocardial infaret size, the oxidative stress markers, myocardial enzymes indicators and inflammatory factors were also analyzed. The expressions of Akt, p-Akt, Bax and Bcl-2 proteins was detected by using Western blot method. The results showed that Hyp preconditioning remarkably improved cardiac constriction and relaxation function, reduced myocardial infarct size and enhanced the activities of oxidative stress markers about correlated to MIRI, such as superoxide dismutase (SOD), catalase (CAT) and glutathione-peroxidase (GSH-Px) and decreased the contents of malondialdehyde (MDA) as compared with MIRI group. Simultaneouly, the levels of myocardial enzymes, i. e. creatine kinase ( CK) and creatine kinase MB isoenzyme (CK-MB), and inflammatory factors, for instance tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6) were decreased. Hyp pretreatment apparently restrained myocardial apoptosis as evidenced by decreasing the level of Bax expression, increasing the levels of phosphorylation of Akt and Bcl-2 expression. These effects were inhibited by LY294002, a blocker of PI3K/Akt signaling pathway. These findings indicated that the cardioprotection of Hyp preconditioning against MIRI may be related to activating PI3K/Akt signaling pathway, upregulating the expression of BCL-2 protein and down-regulating the expression of Bax protein.

To investigate the effects and potential mechanisms of hyperoside (Hyp) on the vascular endothelium function in middle cerebral artery (MCA) ex vivo in rats. Isolated arterial segments from MCAs of rats were used for surveying vasomotoricity in a pressurized chamber. Transmembrane potential was recorded by using glass microelectrodes to evaluate hyperpolarization. Hyp (1 x 10(-6)-1 x 10(-4) mol . L-1) was utilized to observe the effect on 1 x 10(-7) mol . L-1 U46619-preconstricted MCA in rats. The results showed that 1 x 10(-6)-1 x 10(-4) mol . L-1 Hyp significantly induced concentration-dependent vasodilatation and hyperpolarization, leading to the maximal diastolic ratio of (73. 2 ± 6. 1)% and maximal changes in membrane potentials of (-13. 2 ± 2. 2) mV. Hyp still elicited vasorelaxation and hyperpolarization by removal of endothelium in MCA of rat, which was notably attenuated as compared with vascular endothelium-intact group (P <0. 01). In the MCAs preconstricted by U46619 (1 x 10(-7) mol . L-1), Hyp (1 x 10(-6)-1 x 10(-4) mol . L-1) produced concentration-dependent vasorelaxation and hyperpolarizition that were partially attenuated by 3 x 10(-5) mol . L-1 L-NAME(a NOS inhibitor) plus 1 x 10(-5) mol . L-1 PGI2 ,(a synthetase inhibitor). The residual effects were further decreased by 1 x 10(-3) mol . L-1 TEA (an inhibitor of Ca2+-activated potassium channel) or 1 x 10(-5) mol . L-1 PPG (a blocker of endogenous H2S synthese-CSE). Similarly, 1 x 10(-5)-1 x 10(-3) mol . L-1 NaHS (a donor of exogenous H2S) or 1 x 10(-5)-1 x 10(-3) mol . L-1 L-Cys (the substrate of endogenous H2S synthesis) obviously evoked dose-dependent vasodilatation and hyperpolarization of MCA in rats. These findings indicated that Hyp may induce endothelium-dependent and endothelium-independent responses. And the endothelium-dependent vasodilatation may be related to the increases of endogenous H2S that has been promoted Hyp in the endotheliocyte of MCAs, and activated Kca and opening of Kca channels, resulting in the hyperpolarization of vascular smooth muscle cell membrane and subsequent reduction of Ca2+ influx and vasodilation.

OBJECTIVE: to explore the relationship between the maxillary sinus volume and the amount of alveolar bone, and the effect of molar loss upon the maxillary sinus was further analyzed,by measuring adult maxillary sinus volume, sinus ridge distance, and calculating the gasification coefficient of maxillary sinus. METHOD: One hundred and ninety cases (361 maxillary sinus) with CT examinations were collected, they were divided into group A and group B, 121 cases (242 maxillary sinus) of normal subjects served as group A, 42 cases (65 maxillary sinus) with molar part off were B group, in which 31 maxillary sinus with a molar loss were group B1,22 maxillary sinus with two molar loss were B2 group,12 maxillary sinus with three molar loss (one molar remains) were B3 group, 27 cases (54 maxillary sinus) with upper teeth off were C group. Bymeasureing the maxillary sinus volume, sinus ridge distance and the size of the maxillary sinus, calculating the gasification coefficient, we analyzed the relationship between maxillary volume and sinus ridge distance, and comparatively analyzed the differences among the three groups in the size, gasification coefficient, volume of maxillary sinus and sinus ridge distance. RESULT: In the normal group,the volume of maxillary sinus and sinus ridge distance had a correlation coefficient of -0. 63,(P< 0.05); Sinus ridge distance in group A was larger than the other two groups (P<0.05), and larger in B group than in C group (P<0. 05), anteroposterior maxillary sinus diameter and reft-right diameter in C group was greater than in A group and B group(P<0.05), group C gasification coeffiecent was less than A group and B group (P<0. 05). CONCLUSION The volume of maxillary sinus is negatively correlated with the amont of alveolar bone; Upper teeth's shedding promotes maxillary sinus deformation; Maxiuary sinus volume has a tendency to decrease.

The effectiveness and safety of acupuncture-moxibustion for the treatment of agrypnia was systematically reviewed. The clinical randomized controlled trial (RCT) of acupuncture-moxibustion for agrypnia were collected. The literature and document on acupuncture-moxibustion RCT for the treatment of agrypnia that published from January of 2001 to March of 2012 was searched with computer in PubMed, CNKI, Wanfang and VIP database. According to Cochrane Handbook 5. 1. 0, the bias risk and quality assessment were performed on every included trial and RevMan 5. 0 software was applied to make the Meta analysis. Totally 14 researches were included, involving 2662 cases. The Meta analysis showed that the differences of total effective rate between acupuncture-moxibustion and clinical routine treatment were significant [RR = 1.16, 95% CI (1.12, 1.19), Z = 9.32, P < 0.000 01]. The results indicate that total effective rate of acupuncture-moxibustion for agrypnia is obviously superior to that of clinical routine treatment, meaning clinical efficacy of acupuncture-moxibustion is served credit.
