Objective To observe the efficacy of treating cerebral hemorrhage with operation combined with Chinese medicines with the functions of stopping endogenous wind, eliminating phlegm and removing blood stusis. Methods A total of 142 patients after surgery for cerebral hemorrhage were randomly recurited into two groups: a treatment group (n= 41 ) was administrated with Chinese medicines of stopping endogenous wind, eliminating phlegm and removing blood stasis, and a control group (n=41) accepted conventional treatment after the surgery. Results The therapeutic effects in the treatment group was superior to that in control group (X2=13.12, P<0.05) . Conclusion It is effective to treat cerebral hemorrhage with operation combined with Chinese medicines with the functions of stopping endogenous wind, eliminating phlegm and removing blood stasis.

Objective To investigate the possibility of inducing anergy by blocking the CD40/CD154 and B7/CD28 costimulatory pathways and the reversal condition of anergic cells. Methods Splenocyte proliferation in primary mixed lymphocyte reaction (MLR) consisting of BALB/c as responder and C3H as stimulator was measured by the addition of different levels of anti-CD154 and anti-CD80 monocolonal antibody (mAb). To test the reversal condition of anergic cells induced by combined anti-CD154 and anti-CD80 mAbs blocking, C3H or C57BL/6J spleenocytes were irradiated, or different concentrations of recombinant mouse interleukin-2 (rmIL-2), or both C3H splenocytes and rmIL-2 were added to the anergic cells. Results The proliferation of anergic cells treated with both mAbs in the primary MLR was strongly inhibited in a dose-dependent manner. The cells proliferated in response to third party (C57BL/6J) stimulator. The cells did not respond to original (C3H) stimulator, and they also failed to proliferated in response to the addition of exogenous IL-2. Furthermore, the anergic state was reversed by both original (C3H) stimulator and the addition of exogenous rmIL-2. Conclusion The blockade of CD40/CD154 and B7/CD28 costimulatory pathways induces alloantigen-specific anergy, and the anergic state can be reversed by both antigen restimulation and the addition of exogenous IL-2.

Objective To investigate the value of the acupuncture with Medicinal herbs in the treatment of the intractable hiccup after severe craniocerebral injury. Methods Sixty patients diagnosed of intractable hiccup after severe craniocerebral injury were randomly recruited into a therapeutic group and a control group. The therapeutic group was treated with acupuncture and medicinal herbs, while the control group was treated with western medicine. The therapeutic course for both groups was one week. The efficacy was evaluated by observing the cure rate, improvement rate and non effective rate respectively. Results In the therapeutic group :23 patients were cured and the total effective rate was 96.67%;While in the control group: 12 patients were cured and the total effective rate was 70.00%. The effective rate of therapeutic group was obviously better than the control group. Conclusion Acupuncture with medicinal herbs in the treatment of the intractable hiccup after severe craniocerebral injury has good efficacy.

MRF4 is one of muscle regulatory factors and plays critical roles during skeletal muscle development. The muscle development is important for the fish growth which is an important economic factor for the fish culture. To analyze the function of MRF4 in fish, the founder MRF4 antibody was prepared. The flounder MRF4 was cloned, ligated into prokaryotic expression vector pET-30b and expressed in strain E. coli BL21 (DE3). The recombinant flounder MRF4 fusion protein was soluble and purified with cobalt IMAC resins. To prepare MRF4 polyclonal antibodies, rabbits were immunized with the soluble protein and the increasing level of antibodies was determined by Western blot. Also, the endogenous flounder MRF4 was recognized by the anti-serum. The result further proved the existence of the anti-MRF4 antibody in the anti-serum, which will be useful for studies on the function of flounder MRF4.

Objective To explore the effect of neural stem cells (NSCs) transplantation on neurogenesis in an alzheimer' disease mouse model and its related mechanism.Methods A total of 16 12-month old aPP/PS1 double transgenic aD mice were randomly divided into two groups:NSC group (receiving NSCs transplantation in the bilateral hippocampi,n=8) and PBS group as the negative control group (receiving an equal quantity of 0.01M/L phosphate buffer saline,n=8).another 8 wild type mice without any treatment were selected as the positive control group (Wt group).at five weeks after transplantation,the expressions of doublecortin (DCX) and nestin in the hippocampal dentate gyrus (DG) and subgranular zone (SGZ) were analyzed by immunofluorescence staining,the number of positive cells in these regions were counted by confocal microscopy,and Morris water maze (MWM) test was used to assess cognitive function in all mice.Results NSC group showed the enhanced spatial learning and memory ability in Morris water maze (MWM) as compared to PBS group,but it was still lower than that in Wt mice (both P＜0.05).Immunofluorescence staining showed NSCs induced the increased positive cells expressing DCX and nestin in the NSC group as compared with PBS group (F＝85.400 and 55.687,both P＜0.001).However,the number of DCX positive cells was still lower in NSC group than in Wt group (P＜0.05).There was no significant difference in the number of Nestin-positive cells between the NSC group and the Wt group (P＞ 0.05).Conclusions NSCs transplantation can promote endogenous neurogenesis via the increased expression of DCX-and Nestin positive cells in the hippocampal DG/SGZ in aD mice,which improves the cognitive abilities in aD mice in some extent.

Objective To retrospectively analyze computerized tomography (CT) imaging features of colorectal cancer with chronic schistosomiasis in order to improve the diagnostic accuracy.Methods Eighty patients whose diagnosis was pathologically confirmed as colorectal cancer with schistosomiasis were collected from Tongji Hospital and Kunshan Chinese Medicine Hospital from January 2007 to December 2012.All the patients underwent abdominal plain CT and contrast-enhanced CT scan.The lesion location,morphology,size,calcification features,enhancement patterns and cancer metastasis were evaluated and compared by two radiologists who were blind to the diagnosis.Twenty colorectal cancer cases without schistosomiasis from the same area were also collected as controls.Results CT imaging showed that the tumors all occurred in the colon and rectum in 80 patients,mainly in colon descendens,colon sigmoideum and rectum.The lesion was characterized by irregular bowel wall thickening with soft tissue masses,and the average length of impaired intestine was (21.35 ± 4.50) cm.The lesions were solitary in 68 cases (85.0％) and were multifocal in 12 cases (15.0％).Linear,spotty and small patchy calcifications were seen in all the patients,with margins unclear in 59 patients (73.8％) and margins clear in 21 patients (26.2％).Early phase enhancement was seen in 68 cases (85.0％),of which 45 cases (56.2％) had homogenous enhancement and 23 cases (28.8％) had heterogeneous enhancement.Late phase enhancement was seen in 73 cases (91.2％) and necrosis was hardly seen.Only two cases (2.5％) had liver metastasis without lymphatic metastasis.All the 20 colorectal cancer cases without schistosomiasis presented with single lesion,which was characterized by irregular bowel wall thickening and local ulcer.The average length of impaired intestine was (6.90±3.40) cm.No calcification was seen in these lesions.All cases had early phase lesion with remarkable heterogeneous enhancement with low density necrotic area.The late phase enhancement was decreased.Four cases (20.0％) had liver metastasis.Compared to cases without schistosomiasis,cases with schistosomiasis tended to have multifocal (x2=100,P=0.000) and longer lesion (t=45.506,P=0.000),and more calcification (x2=100,P=0.000).The early phase heterogeneous enhancement was less frequent (x2 =88,P=0.000) and late phase enhancement was more frequent (x2=100,P=0.000).The liver metastasis rate was significantly lower (x2 =8.688,P =0.014).Conclusions The CT imaging of colorectal cancer with schistosomiasis is characterized by calcifications inside the tumor with obscured margins and multiple intestinal segments involvement.Hematogenous metastasis and lymphatic metastasis are rarely seen.

Objective To evaluate the effects of different concentrations and different duration of sevoflurane anesthesia on cognitive function in mice.Methods Fifty adult male C57BL/6 mice,weighing 20-24 g,aged 10 weeks,were randomly divided into 5 groups (n =10 each) using a random number table:control group (group C),1.3％ sevoflurane inhaled for0.5 h group (group S1),1.3％ sevoflurane inhaled for 2.0 h group (group S2),2.5％ sevoflurane inhaled for 2.0 h group (group S3),and 2.5％ sevoflurane inhaled for 4.0 h group (group S4).At 2 weeks after anesthesia,Morris water maze test was performed,and the escape latency and frequency of crossing the original platform were recorded.After the end of the test,the mice were sacrificed,and brains were removed to detect the expression of 2B subunit-containing N-methyl-D-aspartate receptors (NR2B) and activated caspase-3 in the hippocampus.Results Compared with group C,the escape latency was significantly shortened,and the frequency of crossing the original platform was increased in S1-3 groups,and the escape latency was prolonged,and no significant change was found in the frequency of crossing the original platform in group S4.Compared with group C,the expression of NR2B in hippocampal tissues was up-regulated in S1-4 groups,and the expression of activated caspase-3 in hippocampal tissues was up-regulated in S3 and S4 groups.Conclusion The reason for different effects of sevoflurane anesthesia on cognitive function is related to the concentration and duration in mice.

Objective To investigate the effect of different durations of low-concentration isoflurane anesthesia on the expression of 2B subunits-containing N-methyl-D-aspartate receptors (NR2B) in the hippocampus of mice.Methods Forty C57BL/6 mice, aged 10 weeks, weighing 20-24 g, were randomly divided into 5 groups (n=8 each) using a random number table: control group (group C);0.7％-1.0％ isoflurane inhaled for 30 min group (group I1);0.7％-1.0％ isoflurane inhaled for 2 h group (group I2);0.7％-1.0％ isoflurane inhaled for 4 h group (group I3);0.7％-1.0％ isoflurane inhaled for 6 h group (group I4).Morris water maze test was carried out at 48 h after the end of anesthesia, and the escape latency and frequency of crossing the original platform were recorded.The mice were sacrificed after the end of the test, and the hippocampi were removed for determination of the expression of activated caspase-3 and NR2B (using Western blot analysis).Results Compared with group C, the escape latency was significantly shortened, and the frequency of crossing the original platform was increased in I1 and I2 groups, no significant changes were found in the activated caspase-3 expression, and the expression of NR2B was up-regulated in I1, I2 and I3 groups, and the escape latency was prolonged, the frequency of crossing the original platform was decreased, the activated caspase-3 expression was up-regulated, and the expression of NR2B was down-regulated in group I4.Conclusion The mechanism underlying the effect produced by different durations of low-concentration isoflurane anesthesia on the cognitive function is related to the expression of NR2B in the hippocampus of mice.
