Objective To explore the levels of neuron-specific enolase(NSE)in serum and cerebrospinal fluid(CSF) of children with convulsion,and its significance to the diagnosis of neuronal damage was evaluated.Methods Sixty patients were enrolled,and they were divided into 4 groups:non-nervous system disease group,peripheral nervous system disease group,brief convulsion group,and prolonged/status convulsion group.The levels of NSE in serum and CSF were detected in 4 groups,and the electroencephalography(EEG) and computed tomography/magnetic resonance imaging(CT/MRI) examinations were taken to observe the changes in patients with convulsion.Results The levels of NSE in serum and CSF of children with convulsion increased significant,especially in the prolonged/status convulsion group.Changes of NSE levels in serum and CSF were similar.Meanwhile,significant changes were found in EEG between the brief convulsion group and prolonged/status convulsion group;but no significantly changes were found in CT/MRI between the 2 groups.Conclusions NSE detection might be valuable to the diagnosis for neuronal damage in early time.The changes of NSE levels are similar to those in EEG,which are more sensitive than the changes in CT/MRI.It is very important to combine the NSE detection in serum or CSF and EEG examination in early time after convulsion for judgement to the neuronal damage and prognosis.

ObjectiveTo investigate the expression of T helper (Th) 17 cells and the related interleukin 17 (IL-17) in acute renal allograft rejection in mice and its significance.Methods We established a mouse renal allograft model,in which mice were randomly divided into a renal isograft group and an acute renal allograft rejection group.Three and 7 d after the transplantation,the serum interferon (IFN)-γand IL-17 levels in the mice were determined by enzyme-linked immunosorbent assay,the percentage of Th1 and Th17 cells in the total kidney-infiltrating lymphocytes was investigated by flow cytometry,and the transplanted kidney species were given routine pathological examination after fixation with 10％ formalin.ResultsCompared with the isograft group,the allograft mice showed a significantly higher content of IL-17 (P ＜0.05 ) but not IFN-γ in the serum 3 d after transplantation,and showed significantly higher serum IL-17 and IFN-γcontents 7 d after transplantation (P ＜ 0.05 ).Also,compared with the isograft group,the allograft mice exhibited significantly higher percentage of Th1 and Th17 cells on both day 3 and day 7 ( P ＜ 0.05 ).In the allograft group,the contents of serum IFN-γand IL-17 and the percentage of Th1 and Th17 cells were significantly higher on day 7 than on day 3 (P ＜ 0.05 ).Routine pathological examination indicated that,as time passed,the allograft mice showed gradually stronger rejection responses.ConclusionTh17 cells might play an important role in the development of acute renal allograft rejection,and IL-17 can be used as an early indicator of acute rejection.

Objective To investigate the effect of propofol on nNOS expression after focal cerebral ischemia-reperfusion in rats and the possible mechanism of protective effect of propofol on brain. Method Seventy-eight male Wistar rats, weighting 250 ~ 300 g, were randomly divided into 3 groups:(1)Sham operation group (S group, n=6) was performed with scham operation; (2) Ischemia-reperfusion group (group I-R, n=36) was subjected to 2-hour right middle cerebral artery occlusion and then reperfusion was followed, saline (1 mg/kg) was injected into the right lateral cerebral ventricle using microsyringe before reperfusion;(3) Propefol group (group P, n=36) was injected with propofol (1mg/kg) into the right lateral cerebral ventricle using microsyringe right after ischemia. Group I-R and group P were divided into 3 subgroups according to the reperfusion time: 1 h, 3 h and 6 h. The neurological function of all rats were tested before reperfusion. The cerebral infarction area of the whole brain was calculated with TIC staining (n=6). The pathological change of brain was observed from HE staining (n=6) and the nNOS protein expression was obtained by immuno- histochemical method (n=6). Results Compared with I-R group, the neurological function was better in group P(P

OBJECTIVETo analyze the rules for acupoint selection of acupuncture and moxibustion in domestic clinical treatment of perimenopausal syndrome based on data mining technology in modern times.

METHODSThe relevant literature were retrieved from Chinese Biomedical Literature Database (CBM), China National Knowledge Infrastructure (CNKI) and Wanfang database on this disease treated with clinical acupuncture and moxibustion in China from 1978 to 2013. The database of acupuncture-moxibustion prescription was set up. The relevant regulations of data mining technology were used to analyze the rules for acupoint selection.

RESULTSTotally, 211 papers, 254 acupuncture-moxibustion prescriptions and 130 acupoints were included. The total frequency of acupoints application was 2193 times, with 14 meridians involved. The utilization of the acupoints in the lower limbs and on the back were 33.0% (723/2193) and 23.8% (521/2193) and those of yin and yang meridians were 51.8% (1136/2193) and 44.0% (965/2193), respectively. The utilization of the specific acupoints accounted for 88.7% (1946/2193).

CONCLUSIONIn clinical treatment of perimenopausal syndrome with acupuncture and moxibustion in modern times, the acupoint selection from involved meridians is the basis, associated with multiple methods of acupoint combination; yin and yang meridians are equally important and the specific acupoints are considered particularly critical in application.

Background and purpose: Syndecan-1 and HPA-1 may be involved in the progression of invasion and metastasis of many malignant tumors, but there are few reports about the relationship between the two gene expressions in gastric carcinomas. This study was aimed to explore the expression of Syndecan-1 and HPA-1 mRNA in gastric carcinoma and their relationship with the invasion and metastasis of gastric carcinoma. Methods: Real-time polymerase chain reation (RT-PCR) was used to detect mRNA of Syndecan-1 and HPA-1 in 58 cases of gastric carcinoma, 58 paired adjacent gastric carcinoma (2 cm from carcinoma), and 58 surgical marginal normal gastric mucosa tissues (5 cm from carcinoma). Then we analyzed their relationship with clinico-pathological characteristics of gastric carcinoma. Results: The upregulation of Syndecan-1 mRNA was significantly higher in normal gastric mucosa (98.3%) than that in paired adjacent mucosa (25.9%) and gastric carcinoma (5.2%) (all P<0.001).The upregulation of Syndecan-1 mRNA was significantly higher in paired adjacent mucosa than that in gastric carcinoma (all P<0.05). The upregulation of HPA-1 mRNA was significantly higher in gastric carcinoma (86.2%) than that in paired adjacent gastric carcinoma (27.6%) and normal gastric mucosa (5.2%) (P<0.001). The upregulation of HPA-1 mRNA was significantly higher in paired adjacent gastric carcinoma than that in normal gastric mucosa (all the same P<0.05). The downregulation of Syndecan-1 and the upregulation of HPA-1 had relationship with the degree of differentiation, depth of infiltration, lymph node metastasis, distant metastasis and TNM staging of gastric carcinoma (P<0.05). Conclusion: The upregulation of Syndecan-1 mRNA was significantly higher in normal gastric mucosa. The upregulation of HPA-1 mRNA was significantly higher in gastric carcinoma. Also, the expression of Syndecan-1 and HPA-1 could predict the invasion and metastasis of gastric carcinoma. Determination of Syndecan-1 and HPA-1 may be of value in the treatment as well as in the prediction for prognosis of gastric cancer.

Objective To evaluate the effect of BML-111 on NF-κB pathway during acute lung injury induced by hemorrhagic shock and resuscitation in rats.Methods Thirty-two adult male Sprague-Dawley rats,weighing 200-250 g,were randomly divided into 4 groups (n =8 each) using a random number table:sham operation group (group S),hemorrhagic shock and resuscitation group (group HSR),BML-111 group,and BML-111 + BOC-2 (lipoxin A4 receptor antagonist) group (group BOC-2).The animals were anesthetized with intraperitoneal pentobarbital sodium.Hemorrhagic shock was induced by blood letting and maintained for 30 min.The animals were then resuscitated for 30 min by infusion of the shed blood and lactated Ringer's solution.In group BOC-2,BOC-2 (50 μg/kg) was injected intraperitoneally before blood letting.In BML-111 and BOC-2 groups,BML-111 (1 mg/kg) was injected intraperitoneally at the beginning of resuscitation.The rats were sacrificed at 2 h after the end of resuscitation and lungs were removed for determination of pathological changes,myeloperoxidase (MPO) activity,intercellular adhesion molecule-1 (ICAM-1) expression (by immunohistochemistry),tumor necrosis factor-alpha (TNF-α) content (by ELISA),and NF-κB p65 and IκB-α expression (by Western blot).Results Compared with group S,the MPO activity,ICAM-1 expression,and TNF-α content were significantly increased,NF-κB p65 expression was up-regulated,and IκB-α expression was down-regulated in group HSR.Compared with group.HSR,the MPO activity,ICAM-1 expression,and TNF-α content were significantly decreased,NF-κB p65 expression was down-regulated,IκB-α expression was up-regulated,and pathological changes of lung were attenuated in group BML-111.Compared with group BML-111,the MPO activity,ICAM-1 expression,and TNF-α content were significantly increased,NF-κB p65 expression was up-regulated,and lκ:B-α expression was down-regulated,and pathological changes of lung were aggravated in group BOC-2.Conclusion BML-1 11 inhibits activation of NF-κB pathway and inflammatory responses,thus mitigating acute lung injury induced by hemorrhagic shock and resuscitation in rats.
