OBJECTIVETo explore the effect of Sedum sarmentosum Bunge Extract (SSBE) on severe acute pancreatitis (SAP) induced acute lung injury (ALI) model rats and their excessive inflammatory reactions.

METHODSForty-two healthy adult male Sprague-Dawley (SD) rats were randomly divided into 3 groups, the sham-operated control group (C), the SAP group (SAP), and the SSBE treated group (SSBE), 14 in each group. SAP induced ALl rat model was induced by retrograde injection of 5% sodium taurocholate (1 mL/kg) into the pancreatic duct. SSBE (100 m/kg) was administrated subcutaneously after the establishment of the SAP model. Equal dose of SSBE was injected again 12 h later. Equal volume of normal saline was administrated in the same way for rats in the C group and the SAP group. Rats were sacrificed after successful modeling and samples taken at 12 and 24 h. Pathological changes in the pancreas and the lung tissue were observed under light microscope. The ascites, serum amylase (AMS), wet/dry proportion (W/D) of the lung tissue, activities of myeloperoxidase (MPO), interleukin-1 (IL-1), IL-6, and tumor necrosis factor-alpha (TNF-alpha) were also measured.

RESULTSAscites and serum AMS activities significantly increased; MPO, IL-1, IL-6, TNF-alpha contents, and W/D ratio also significantly increased in the SAP group, when compared with the C group (P<0.05). Compared with the SAP group, those parameters were all attenuated in the SSBE group at 12 and 24 h (P<0.05, P<0.01). Pathological changes in the pancreas and the lung tissue were alleviated in the SSBE group under light microscope. The injury degree ranged between that of the C group and the SAP group.

CONCLUSIONSSBE could relieve the ALl in SAP model rats, which could be achieved through alleviating inflammation responses of SAP rats.

OBJECTIVETo study the changes and significance of serum hypoxia-inducible factor-1α (HIF-1α), endothelin-1 (ET-1) and calcium (Ca(2+)) levels in neonates with hypoxic pulmonary hypertension (HPH).

METHODSSeventy-five neonates with HPH (29 mild, 25 moderate and 21 severe) and 22 hospitalized neonates with non-HPH (control group) were enrolled. Pulmonary artery systolic blood pressure (PASP) was measured by bedside echocardiography within 24 hrs after birth. Serum levels of HIF-1α and ET-1 were measured using ELASA. Serum Ca2+ concentrations were measured with ion selective electrode.

RESULTSSerum levels of HIF-1α and ET-1 in the HPH group increased significantly compared with those in the control group (P<0.01), and were positively related with PASP (Rhif-1α=0.75, P<0.01; Ret-1=0.56,P<0.05). Serum Ca2+ levels in neonates with severe HPH were significantly lower than those in the control group (P<0.05). There were no correlation between serum Ca2+ levels and PASP.

CONCLUSIONSSerum HIF-1α and ET-1 levels are positively related with PASP in neonates with HPH, suggesting that serum HIF-1α and ET-1 may be involved in the occurrence of neonatal HPH. Serum Ca2+ levels are reduced in severe neonates with HPH, suggesting that serum Ca2+ may play a role in the occurrence of severe HPH.

OBJECTIVETo study the role of Tei index in the evaluation of left ventricular dysfunction in neonates with hypoxemia.

METHODSFifty-two neonates with hypoxemia (20 mild, 16 moderate, 16 severe) and 40 normal neonates (control group) were enrolled. On postnatal days 1, 3 and 7, Doppler echocardiography was used to measure the indexes reflecting systolic and diastolic cardiac functions: ejection fraction of left ventricular (LVEF), E/A ratio of mitral value and Tei index of left ventricular (LV-Tei).

RESULTSLVEF and E/A ratio of left ventricular in the moderate hypoxemia group were significantly lower than those in the control group on postnatal days 1 and 3 (P<0.01). LVEF and E/A ratio of left ventricular in the severe hypoxemia group were significantly lower than those in the control group on postnatal days 1, 3 and 7 (P<0.01 or 0.05). Compared with the control group, LV-Tei increased significantly in the mild hypoxemia group on postnatal day 1 and increased significantly in the moderate and severe hypoxemia groups on postnatal days 1 and 3 (P<0.01). There was a negative correlation between PaO2 and LV-Tei in the hypoxemia group on postnatal days 1 and 3 (r=-0.50, P<0.05; r=-0.71, P<0.01 respectively).

CONCLUSIONSLV-Tei can be used as a sensitive indicator for the evaluation of left ventricular dysfunction in neonates with hypoxemia.

Acetaminophen (APAP, also known as paracetamol)-induced liver injury is the leading cause of drug-induced liver injury in the world. Wuzhi Tablet (WZ, an ethanol extract of Schisandra sphenanthera) is widely used in clinical practice to protect liver function. Our previous studies have shown that pretreatment with WZ for 3 days can significantly protect against APAP-induced liver injury; however, the effect of different intervals between APAP and WZ treatment on APAP-induced liver injury remains unclear. In this study, the change in liver injury indexes, APAP metabolites, and the activity of cytochrome P450 (CYP450) enzymes after treatment with WZ and APAP at different intervals were determined. The animal experiment was reviewed and approved by the Animal Ethics Committee of Sun Yat-sen University. The results show that 0 h, 0.5 h, and 2 h pretreatment with WZ significantly protected against APAP-induced liver injury in mice, as evidenced by a significant decrease in biochemical parameters such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), and malonaldehyde (MDA). WZ inhibited the metabolic activation of APAP mediated by CYP450 enzymes and reduced the formation of APAP metabolites. This study further demonstrates that pretreatment with WZ at different intervals (0 h, 0.5 h, and 2 h before APAP dosing) exerts a significant hepatoprotective effect against APAP-induced liver injury, and a single-dose of WZ inhibits the activity of CYP450 enzymes related to APAP metabolic activation, thereby protecting against APAP-induced hepatotoxicity.

OBJECTIVETo explore the effects of integrative medicine (IM) rehabilitation protocolon motor function, activity of daily living, and quality of life (QOL) in hemiplegia patients after stroke.

METHODSTotally 120 patients with post-stroke hemiplegia were allocated to four groups using sealed envalope drawing, i.e., the rehabilitation group, the Chinese medical treatment group, the acupuncture group, and the comprehensive rehabilitation group, 30 cases in each group. Based on routine rehabilitative training, patients in the Chinese medical treatment group, the acupuncture group, and the compre-hensive rehabilitation group received standardized treatment based on syndrome typing, Shi's Consciousness-Restoring Resuscitation acupuncture, Chinese herbs + acupuncture comprehensive rehabilitatino protocol, respectively. The treatmet cycle consisted of 4 weeks with 24-week follow-ups. Fugl-Meyer motor assessment (FMA), Modified Barthel Index (MBI), and Stroke-Specific Quality of Life Scale(SS-QQL), and safety assessment were taken as main effect indices before treatment, at week 4 of treatment, at week 12 and 24 of follow-ups, respectively.

RESULTSThere was no statistical difference in FMA score, MBI score, SS-QOL score among the four groups before treatment (P > 0.05). These scores were significantly improved in the four groups at week 4 of treatment, week 12 and 24 of follow-ups, respectively (P < 0.05). Besides, FMA score and SS-QOL score were significantly improved in the comprehensive rehabilitation group at each corresponding time point, as compared with other treatment groups (P < 0.05).

CONCLUSIONSThe comprehensive protocol could significantly improve motor function, activity of daily living in hemiplegia patients after stroke, and further improve their QOL. Its effect was better than other single treatment.

Objective To study the sensitivity and specificity of gold-immunochromatography assay (GICA) for detection of Yersiniapestis(Y. pestis ) F1 antigen. Methods Viscera organ(liver and spleen) specimens of 308 mice with virulent Y. pestis infection and 225 control specimens of rats(217 Spermophilus dauricus, 5 mice,3 guinea pigs) were detected by GICA dipstick with monoclonal antibody against plague F1 antigen (F1MAb).Meanwhile, micro-method of reverse indirect hemagglutination assay(RIHA) and bacteria culture were carried out for parallel testing. Results Bacteriological examination of 225 control specimens, and F1 antigen detected with GICA and RIHA were all negative. No cross-reaction with related Yersinia pseudotuberculosis at 1 x 108 cfu/ml level was found in GICA and RIHA. Detection sensitivity of Y. pestis by GICA and RIHA were 2.5 × 105 cfu/ml and 2.0 × 105 cfu/ml, respectively, and of F1 antigen were 1μg/L and 10 μg/L, respectively. Coincidence was 97.94% (522/533) between GICA and bacteriological test, Kappa = 0.959, and the difference was statistically insignificant(x2 = 0.36, P ＞ 0.05); and 97.94%(522/533) between GICA and RIHA, Kappa = 0.959, with statistically significant difference in the positive detection rates(x2 = 9.09, P ＜ 0.05). Out of the 308 infected mice, 284 were positive of plague bacterial cultured, In 284 samples with positive bacterial culture, there were 280 of positive detected by GICA for F1 antigen, positive rate of F1 antigen was 98.59%, higher than that by RIHA[the positive rate of 96.13%(522/533)], with statistically significant difference(x2 = 5.14, P ＜ 0.05). Sensitivity of GICA was 98.59% (280/284), specificity was 97.19% (242/249), positive predictive value (PPV) was 97.56% (280/287),negative predictive value ( NPV ) was 98.37% (242/246), and Youden index was 0.9578. Conclusions GICA is sensitive and specific, fast and simple in detection of F1 antigen of the plague. It's a valuable detection technique for early and rapid diagnosis of plague.

OBJECTIVETo study the surgical treatment of recurrent laryngeal nerve (RLN) injury caused by thyroid operation.

METHODSFrom 1970 to 2001, 50 patients with RLN injury were caused by thyroid operation. The causes, location, type, operative procedures and follow-up were retrospectively analyzed.

RESULTSUnilateral RLN injury occurred in 46 cases and bilateral nerve injury in 4 cases. The RLN injuries were located within 2cm below the point of RLN entering to throat in 45 nerves (83.3%), other places in 6 nerves (11.3%), and unknown location in 3 nerves (5.4%). Transection of the nerve was found in 19 nerves (36.5%), suture or scare pressing the nerve in 35 nerves (64.8%). All the injured nerves were repaired surgically. Meanwhile all 4 patients with bilateral RLN injuries underwent tracheotomy. Of the 50 cases, 44 cases (88.0%) were followed up for more than 1.5 years. Among the 44 followed-up patients, phonation was restored to normal or obvious improvement in 42 cases (95.5%), and improvement in 2 (4.5%). Of the 35 patients with 39 nerves underwent indirect or direct laryngoscopy, the affected vocal cord movement entirely recovered in 21 cords (53.8%), partially recovered in 7 cords (17.9%), uncovered in 11 cords (28.3%). There was no relation between the recovery of phonation or vocal cord movement with the timing or the procedure of repairing operation.

CONCLUSIONSThe location of most RLN injuries caused by thyroid surgery are just below the point of RLN entering to throat, and most are mechanical injury, and need operation to resolve the cause. Once the RLN injury is made, an operation should be performed as early as possible.

Objective To provide the foundation of theory on prevention of hypoxia-induced pulmonary hypertension (HPH) by investigating the concentrations in the serum and expression levels in the lung tissue,and by studying the roles of hypoxia-inducible factor-1 α (HIF-1 α),endothelin-1 (ET-1) and adrenomedullin (ADM) in newborn rats with HPH.Methods Seventy-two newborn rats were randomly divided into hypoxic group(hypoxia exposure) and normoxic group.The mean pulmonary arteria pressure (mPAP),concentrations in the serum and expression levels in the lung tissue of the above-mentioned factors were measured in these neonatal rats after 3,5,7,10,14 and 21 days,including hypoxic group and normoxic group,respectively.The morphology of pulmonary arterioles was observed and the vascular remodeling indexes were measured.Results 1.Compared with the normoxic group,the mPAP increased with the prolonged hypoxic time in the hypoxic group(P ＜ 0.05).2.Concentrations in the serum and expression levels in the lung tissue of HIF-1 α were higher than those of the normoxic group on 3,5,7,10,14 days (all P ＜ 0.05).The serum concentration of ET-1 elevated significantly in the hypoxic group at each time point,and ET-1 mRNA increased only on 3 and 5 days of the hypoxia group.The serum concentration of ADM level in the hypoxic group was higher than that of the normoxic group on 3 and 5 days,but lower than the normoxic group after 14 and 21 days of hypoxia,and the expression of ADM mRNA in the lung tissue was higher on 3 and 5 days in the hypoxic group.3.Morphology and ultrastructure of the pulmonary arteries change were found after 7 days of hypoxia exposure.Conclusions HIF-1α may regulate ET-1 and ADM in the pathogenesis of HPH.ET-1 plays a powerful role by pulmonary vasoconstriction and vascular remodeling,whereas ADM displays the protective effects on blood vessels in the early stages of HPH.Pulmonary vascular remodeling occurs in the hypoxic group after 7 days of hypoxia.
