OBJECTIVEYoung C57BL/6 (B6) mice were treated with a specific tolerogen-dual analogue (Lys262-Ala207) intranasally to observe its effect on the invasion process of mice model and the clinical symptoms, to assess its clinical effects, and to explore the underlying mechanisms and feasibility of nasal mucosal tolerance explored.

METHODSPassively transferred myasthenia gravis (PTMG) was induced by mAb35 on B6 young female mice. Sixty mice were divided equally into three groups: tolerance group, model group and control group. Lys262-Ala207 was given intranasally (250 microg/mouse) to tolerance group with mAb35 for 10 successive days before immunization. Model group received PBS 50 microl only. The body weight and clinical scores were evaluated. The serum levels of AChRAb and the main cytokines (IL-4, IFN-gamma, TGF-beta1) were detected with ELISA.

RESULTSThe model group had typical myasthenia symptoms. B6 mice of tolerance group had less severe symptoms compared with control groups. The clinical symptoms of tolerance group were relieved. The level of AChRAb in tolerance group [(16.01 +/- 1.09) mg/L] was significantly lower than that of model group [(28.12 +/- 1.28) mg/L] (t = 44.37, P < 0.01). IL-4 and IFN-gamma levels in tolerance group [(141.02 +/- 3.11) ng/L, (187.99 +/- 4.67) ng/L] were significantly lower than those of model group [(193.37 +/- 3.95) ng/L, (320.46 +/- 2.14) ng/L] (t = 37.20, 51.69, P < 0.01). The level of TGF-beta1 in tolerance group [(437.19 +/- 1.93) ng/L] was higher than that of model group [(175.63 +/- 3.12) ng/L] (t = 36.07, P < 0.01). But there were still significant change as compared to those in control group (t = 26.65, 31.05, 49.02, P < 0.01).

CONCLUSIONSNasal administration of Lys262-Ala207 ameliorated muscular weakness in PTMG young mice. The therapeutic effect is possibly correlated with the function of immune system.

Objective To study the peripheral neutrophils activation mesenteric lymph in a murine hemorrhagic shock model.Methods In this study,18 male Sprague-Dawley rats were evenly divided into 3 groups.Group A:rats subjected to hemorrhagic-shock and Ringer's lactate(RL)resuscitation,group B:rats suffered from no blood loss but received same amount of RL as in group A,and group C:rats experience no blood loss nor RL transfusion.The main mesenteric lymphatic duct was cannulated with 24G catheter in all rats.In group A,blood was withdrawn through femoral artery until mean arterial pressure reached 40?5 mm Hg,the pressure was maintained for 90 min.In group B,no blood was withdrawn,these two groups received RL 3 times as the blood withdrawn,in group C,no blood was withdrawn,nor fluid was given.Lymph samples during pre-shock,the first hour and second hour post-shock or sham shock were collected and was used to induce PMN activation.Mesenteric lymph-induced rat PMN(polymorphonuclear neutrophil)adhesion molecule expression(CD18 and CD11b)and neutrophil respiratory burst activity was examined using a FACS flow cytometer.Results In group A,1st hour and 2 nd hour post-shock mesenteric lymph induced rat PMN activation,the expression of CD11b was 63.28?1.13%,61.23? 1.16%,respectively,compared with control(P

Objective To evaluate laparoscopic radical cholecystectomy for T2 gallbladder cancers.Methods A retrospective analysis was made on 44 patients with pathology confirmed T2 gallbladder cancer undergoing laparoscopic vs open radical cholecystectomy.The clinicopathological and follow-up data were compared.Results Laparoscopic cholecystectomy was performed in 32 patients,the implantation metastasis rate of this approach has no statistical differences compared with the open cholecystectomy (P =1.000).26 patients underwent laparoscopic radical resection and the remaining 18 patients underwent open radical resection.There was no statistical difference in operation time (P =0.953),blood loss (P =0.193)and postoperative complications (P =1.000),but the laparoscopic radical resection group is superior to the open group on postoperative pain grading (P =0.022),ambulation time (P =0.000),nothing per mouth time (P =0.000) and length of hospital stay (P =0.048).The mean number of lymph nodes retrieved was 5 ±4 (range 1-12) in the laparoscopic radical group and 6 ± 3 (range 1-12) in the open group (P =0.983);the 1,3,5 year survival rates was 92.3％,70.3％,61.5％ and 92.3％,76.3％,69.3％,respectively(P =0.473).Conclusions Initial laparoscopic cholecystectomy does not increase the rate of seeding metastasis in the context of intact gallbladder carcinoma.Totall laparoscopic radical resection is feasible in selected T2 gallbladder cancer patients.

OBJECTIVETo observe the effect of Qingfei Peiyuan Micro-pill (QPM) on HIV/AIDS patients with pulmonary infection of phlegm heat obstructing lung syndrome (PHOLS).

METHODSTotally 141 HIV/AIDS patients with pulmonary infection of PHOLS were randomly assigned to the treatment group (94 cases) and the control group (47cases). On the basis of Western medicine, patients in the treatment group took QPM. The therapeutic course for all was 28 days. The improvement of symptoms and signs was observed. The body temperature (BT), chest X ray, and white blood cells (WBCs) were detected.

RESULTSThe Chinese medical syndrome score was lower in the treatment group than in the control group at the 7th, 21st, and 28th day of treatment, showing statistical difference (P < 0.05). The efficacy was better in the treatment group than in the control group at the 7th, 21st, and 28th day of treatment, showing statistical difference (P < 0.05). The BT was lower in the treatment group than in the control group on the 7th day. There was no statistical difference in the patient number with normal WBCs on the 7th day (P > 0.05). But there was statistical difference in the patient number with normal WBCs on the 14th, 21st, and 28th day of treatment (P < 0.05). There was no statistical difference in the patient number with normal chest X ray on the 7th and 28th day of treatment (P > 0.05). But there was statistical difference in the patient number with normal chest X ray on the 14th and 21 st day of treatment (P < 0.05).

CONCLUSIONQPM had certain complementary effect on HIV/AIDS patients with pulmonary infection of PHOLS.

To investigate the mechanism of agarwood formation in Aquilaria sinensis induced by Lasiodiplodia theobromae, the fermentation liquor of L. theobromae was analyzed qualitatively and quantitatively by gas chromatography-mass spectrometry (GC-MS). JAs were detected in the fermentation liquor. The effect of the fermentation liquor on the abundance of sesquiterpenes in the callus of A. sinensis was analyzed by solid phase microextraction-gas chromatography-mass spectrometry (SPME-GC-MS). And the fermentation liquor stimulated alpha-guaiene, alpha-humulene and delta-guaiene biosynthesis in calli. It was inferred that L. theobromae produced JAs, which resulted in a significant increase of sesquiterpenes in A. sinensis.

OBJECTIVETo analyze the variation of serum insulin levels in critically ill children and investigate the underlying mechanism and clinical significance to provide the basis for treatment.

METHODTotally 332 critically ill children admitted in pediatric intensive care unit (PICU) of Hunan Children's Hospital from Nov., 2011 to April, 2012 were studied. The high insulin group (n = 332) was defined as insulin levels within 24 h > 11.1 mU/L and was divided into 2 groups: mildly elevated group (n = 194): 11.10 - 33.30 mU/L, increased three times group (n = 138): > 33.3 mU/L. Insulin, C-peptide and blood glucose were measured within 24 hours after admission, on day 3 and 7. Other results of inflammatory markers, lactate, cardiac enzymes, amylase, pancreatic ultrasound, hepatic and renal function as well as indicators related to severity and prognosis were recorded after admission.

RESULTThe peak of insulin level was seen on day 1, then presented a downward trend and reached the normal level on day 7. The peaks of blood glucose and C-peptide level were seen on day 1 then declined, the levels on day 7 were still slightly higher than normal level. The insulin level on admission (41.47 ± 30.85) mU/L were positively correlated with lactic acid (2.29 ± 1.81) mmol/L and procalcitonin level (5.08 ± 6.70) ng/ml (r = 0.370, P = 0.000; r = 0.168, P = 0.002) (P < 0.01). The insulin level on admission in children with 1 organ failure (41.24 ± 22.60) mU/L or 2 or multiple organ failure (48.98 ± 22.17) mU/L was higher than that in children with non-organ failure (34.11 ± 29.84) mU/L (U = 1621.001, P = 0.000;U = 1300.000, P = 0.000) (P < 0.01). The insulin level on admission in death group (52.99 ± 32.34) mU/L was higher than that in survival group (32.85 ± 24.10) mU/L (U = 1585.000, P = 0.000) (P < 0.01). Ten cases in death group were complicated with pancreatic damage and the average insulin level on admission was (65.29 ± 50.53) mU/L.

CONCLUSIONThe high insulin level was correlated with the degree of inflammatory response, ischemia and hypoxia. The high insulin level in critically ill children was relevant to the pancreatic damage, the severity of the disease, organ dysfunction, and evaluation of prognosis.
