OBJECTIVETo evaluate the efficacy and safety of Yigan Fupi Decoction (YFD) in the treatment of irritable bowel syndrome with diarrhea (IBS-D) patients.

METHODSA randomized controlled clinical trail was carried out in patients with IBS-D. All patients were randomly assigned to the treatment group (58 cases, treated with YFD) and the control group (58 cases, treated with Pinaverium Bromide Tablet). The treatment course was 4 weeks for all patients. The total effective rate, the stool property and state, the quality of life (QOL), and TCM syndrome efficacy were assessed by IBS bowel symptom severity scale (IBS-BSS), IBS defecation state questionnaire (IBS-DSQ), IBS quality of life questionnaire (IBS-QOL), and traditional Chinese medicine pattern curative effect scoring system (TCM-PES) before and after treatment.

RESULTSThere was no statistical difference in the total effective rate between the two groups (82.76% vs. 77.59%, P > 0.05). The treatment group was superior in the total IBS-BSS integral to the control group (P < 0.05). The total effective rate of improving the stool property was better in the treatment group than in the control group (81.03% vs. 72.41%, P < 0.05). Besides, the number of days for emergent defecation among 10 days was less in the treatment group than in the control group (P < 0.05). The improvement of the total IBS-QOL integral and the total integral of TCM syndrome were better in the treatment group than in the control group (P < 0.01). The total effective rate of TCM-PES was better in the treatment group than in the control group (84.48% vs. 70.69%, P < 0.05).

CONCLUSIONYFD was effective in the treatment of IBS-D patients of Gan-qi invading Pi syndrome, and could effectively relieve bowel symptoms, improve the stool property and the defecation frequency, elevate their QOL, and attenuate Gan-qi invading Pi syndrome with favorable safety and compliance.

Background Allograft rejection is a main cause of failure of penetrating keratoplasty,especially in the patient with high risk of rejection condition.Previous study on allograft rejection mechanism focused on limbal and corneal neovascularization,but these factors did not explain all the phenomena of allograft rejection.Research found that immune cells appeared in iris and ciliary body when rejection occurred,but the relationship between these immune cells and allograft rejection is unclear Objective This study was to evaluate the relationship between diversity of vascular permeability in the iris and ciliary body and allograft rejection after penetrating keratoplasty.Methods Seventy clean eight-week-old BALB/c mice were divided into allogeneic corneal transplantation group (60 mice) and blank control group (10 mice).Allogeneic corneal transplantation was performed with the same age of C57BL/6 mice as donor and BALB/c mice as the recipients.The grafts were examined under the slit lamp microscope and scored based on the criteria of Hegde.The mice were sacrificed and iris and ciliary tissue were obtained 5,10 days and rejection after surgery.Immunohistochemistry and reverse transcription PCR (RT-PCR) was used respectively to detect the expression diversities of occludin,zonula occludens protein-1 (ZO-1),matrix metalloproteinase-9(MMP-9),major histocompatibility complex-Ⅱ (MHC-Ⅱ),and CCR5,CCR7 and their mRNA in iris and ciliary body.Image-J image analysis software was used to calculate the quantity of positive cells on iris wholemount,and absorbance of target genes (A values).The use and care of the experimental animals complied the ARVO Resolution on the Use of Animals in Research.Results The mean survival time of corneal gratts was (17±3) days after operation.The mean score was 0.6 in 5 days and 0.5 in 10 days,and 3.3 in 18 days after operation.Expression of ZO-1 reduced significantly,and that of MMP-9 increased obviously at the time of rejection.MHC Ⅱ + cells were scattered in iris and ciliary body in normal mice,and the number of the positive cells (cells/field) was increased after operation with a peak value when rejection occurred.A significant difference was seen between normal mice and rejection mice (1559.67±350.29 vs.4021.83±495.18) (P=0.000).The expressions of occludin mRNA and ZO-1 mRNA in the iris and ciliary body decreased obviously in the rejection mice.Compared with normal mice,theA value of ZO-1 and occluding were 36.74±3.13 vs.110.11±11.88 and 57.54±3.41 vs.59.90±3.50respectively,with significant differences between them (all P＜0.05).The expressions of MMP-9 mRNA,CCR5 mRNA and CCR7 mRNA in the iris and ciliary body increased gradually with the time lapse after operation and peaked when the rejection appeared.The A value of MMP-9 mRNA,CCR5 mRNA and CCR7 mRNA were significantly higher than those of normal mice (20.29±1.19 vs.2.77±0.85 for MMP-9 mRNA; 35.43±2.56 vs.9.11±0.29 for CCR5 mRNA,and 60.83±0.87 vs.0.89 ±0.95 for CCR7 mRNA) respectively (all P＜0.05).Conclusions The permeability of vascules in the iris and ciliary body increase during the allograft rejection after penetrating keratoplasty.Increased antigen presenting cells were also detected.

Objective To explore the value of color doppler ultrasonography by bed side in the early diagnosis of HIE in full term neonates.Methods The changes of cerebral parenchymal and cerebral arterial blood stream parameter on 35 cases of neonates clinically diagnosed HIE of mild and moderate degree and 40 cases of normal newborns on the 24,48 and 72 hours after birth were observed by color doppler ultrasonography by bed side.Results 1.The cerebral parenchyma was even echo in normal newborns,but it was maldistributed and reinforced in mild asphyxia neonates and it was more serious in moderate degree.The echo of cerebral parenchyma in mild degree was near normal in 48 hours after birth,while the echo of cerebral parenchyma in moderate degree was still maldistributed and reinforced in 48 and 72 hours after birth.2.There was obvious changes in the cerebral arterial blood stream parameter and hemodynamics of the asphyxia newborns compared with normals.The systolic peak velocity(Vs)and end diastolic velocity(Vd)of the cerebral arteries in mild and moderate degree were obviously lower than that of control group in 24,48 hours after birth(Pa0.05).3.Resistance index(RI)of the cerebral arteries in mild and moderate degree were higher than that of control group in 24,48 hours after birth(Pa0.05).Conclusion Color doppler ultrasonography by bed side is a convenient,noninvasive method for diagnosing HIE.

BACKGROUNDSeveral randomized controlled trials (RCTs) have compared endoscopic and symptomatic relapses in patients with erosive gastroesophageal reflux disease (GERD). We have summarized current evidence for rabeprazole 10 or 20 mg once daily for GERD maintenance treatment over 1 or 5 years.

METHODSMEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials were searched, through August 2012, for eligible RCTs of adults with erosive GERD. The efficacies of rabeprazole 10 and 20 mg/d were compared.

RESULTSThe search identified 288 citations, and five RCTs containing 1480 patients were considered eligible. Heartburn relapse rates did not differ significantly between patients treated with rabeprazole 10 and 20 mg/d for 1 year (relative risk (RR) = 1.29; 95% confidence interval (CI): 0.97-1.72), but differed in patients treated for 5 years (RR = 1.274; 95% CI: 1.005-1.615). Endoscopic relapse rates differed significantly between rabeprazole 10 and 20 mg/d for 1 year (RR = 1.92; 95% CI: 1.21-3.06), for 5 years (RR = 1.667; 95% CI: 1.073-2.589), and in combined 1- and 5-year maintenance trials (RR = 1.785; 95% CI: 1.298-2.456).

CONCLUSIONRabeprazole 20 mg/d was superior to rabeprazole 10 mg/d in preventing endoscopic relapse of erosive GERD, but that the two dosages were equivalent in symptomatic relief over 1 year.

Objective To investigate the relationship of the levels of peroxisome proliferator- activated receptor-?(PPAR-?)mRNA,MMP-9 with the severity of coronary artery lesions in patients with coronary heart disease(CHD).Methods One hundred and fifty three patients with CHD who underwent coronary angiography were admitted.The expression of PPAR-?mRNA in lymphocytes of peripheral blood was detected by using RT-PCR,the level of MMP-9 enzyme was measured by enzyme-linked immunosorent assay,and the severity of coronary artery lesions were analyzed. Results As compared with control(0.624-0.13),PPAR-?mRNA expression was significantly lower in CHD patients(0.4+0.12).Negative correlation was found between PPAR-?mRNA and the classification(r=-0.56,P＜0.01)of coronary artery lesions,so was the number of coronary artery lesions(r=-0.42,P＜0.01).MMP-9 level was significantly higher in CHD patients(1.27?0.16)?g/L than that in controls(1.21?0.05)?g/L.Positive correlation was found between MMP-9 level and the classification(r=0.36,P＜0.01)of coronary artery lesions,so was the number of coronary artery lesions(r=0.30,P＜0.01).Negative correlation was also found between PPAR-?mRNA expression and MMP-9 level.Conclusions PPAR-?is a negative regulator of coronary artery lesions and PPAR-?inhibits the activation of MMP-9.It may be a valuable method for protecting patients from the incident of coronary artery disease to activate the expression of PPAR-?and decrease the level of MMP-9.

Objective To evaluate the value of measuring ankle brachial index (ABI) for diagnosing peripheral arterial disease(PAD)compared with conventional digital subtraction angiography (DSA) as the reference standard.Methotis A total of 383 consecutive inpatients (245 male.mean age 64.1 ±11.7 years) underwent both conventional DSA and ABI measurements.Results The rate of statin intervention was 90.9%,ACEI 69.2%,antiplatelet 96.6% and β-blockers 67.9%.The intravascular stenosis was classified into six degrees:normal,<30%,30%-49%,50%-69%,70%-89% and≥90%.Compared to the traditional gold standard (DSA) in diagnosis PDA.the ABI value decreased in proportion to the sevefity of PAD (the ABI value was 1.08±0.11,1.05±0.16,0.99±0.17,0.66±0.24,0.55±0.28 and 0.54±0.00 respectively in the six ranks).There was a significant correlation between DSA and ABI in diagnosis PAD.Conclusion ABI measurement is an accurate and reliable non-invasive altemative to conventional DSA in the assessment of lower extremity arteries in patients with peripheral arterial disease.

OBJECTIVETo investigate the influence on costal cartilage reparative regeneration by replanting the small blocks of autogeneic cartilage into the perichondrial pocket at the donor-site.

METHODS16 rabbits (8-10 weeks old, 1.8-2.2 kg) were randomly divided into four groups as three experimental groups and one control group. The 1.5 cm in length of costal cartilage defect was made in experimental groups with the perichondrium and costochondral junction left completely intact. The cartilage defect was closed by 3 methods as saturation directly, or replanting the small blocks of autogeneic cartilage, or plugging bio-protein jelly after cartilage replanting. Each experimental group was handled with two methods in two sides of costal cartilage. No operation was performed in control group. All the rabbits were sacrificed 16 weeks after operation. The appearance of thoracic cage and new-formed tissue at the defect site were examined grossly. Haematoxylin-eosin staining was performed to evaluate the characteristics of new-formed tissues and biomechanical detection was used to measure intension of new-formed tissues.

RESULTSThe appearance of thoracic cage was normal in every experimental group. Histological study showed that the defect was filled with abundant fibrous tissue in each group. The chipping of cartilage survived effectively with little proliferation. Biomechanical detection showed that the intension of new-formed tissue in the non-replanted group [(193.92 +/- 41.41) N] was obviously less than that in the replanted group [(318.88 +/- 28.28) N], or bio-protein jelly group [(301.00 +/- 39.52) N], or control group [(300.54 +/- 38.35) N] (P < 0.01). Furthermore, there was no statistical difference between the latter three groups (P > 0.05).

CONCLUSIONSAlthough replanting the chipping of cartilage can't promote reparative regeneration of hyaline cartilage, it can definitively strengthen the intensity of new-formed tissue, reinforce thoracic stability. It may also indirectly decrease the incidence rate of postoperative chest wall deformity.

OBJECTIVETo investigate the factors affecting clinical therapeutic effect on acute tetramine poisoning.

METHODSUsing Logistic regression to analyze the relationships among the degree of tetramine poisoning, time of onset, time of admission, exposure history, sex, age, unithol, gastric lavage, etc with the death of poisonded patients.

RESULTSThe fatality rate of patient with tetramine poisoning who got gastric lavage was less than that who did not (5.85% vs 38.00%, P < 0.01). In patients who got gastric lavage, the fatality rates were increased with the degree of tetramine poisoning (control: 0%, mild poisoning: 3.07%, severe poisoning: 9.14%, P < 0.05). There was no significant difference in fatality between using unithol and not using patients (7.22% vs 8.25%, P > 0.05).

CONCLUSIONUnithol has no significant influence of clinical therapeutic effect on tetramine poisoning patients and dose not reduce the fatality rate of patient with tetramine poisoning, but gastric lavage and the degree of tetramine poisoning do. Logistic regression analysis showed that gastric lavage is the main factor affecting the therapeutic effect on tetramine poisoning.
