Objective To explore the characteristic of SPECT/CT imaging of osteolytic lesions with increased bone metabolism and its correlation with CT manifestation. Methods Twenty?one cancer patients with bone metastases underwent 99 Tcm?MDP SPECT/CT imaging ( 13 males, 8 females; age: ( 60. 52 ± 6?85) years) were retrospectively studied. The imaging characteristic of the lesion with high uptake of 99Tcm?MDP was observed and the correlation between the lesion/background ( L/B ) ratio and CT manifestation were analyzed. One?way analysis of variance, two?sample t test and linear correlation analysis were used. Results A total of 111 lesions were found in 21 patients by 99 Tcm?MDP whole?body bone scan, and 125 le?sions were found by SPECT/CT imaging, including 111 lesions with increased bone metabolism and abnor?mal CT manifestation and 14 osteolytic lesions with decreased bone metabolism. In 111 lesions with in?creased bone metabolism, there were 23(20.72%) osteolytic lesions, 54 (48.65%) osteoblastic lesions and 34 (30.63%) mixed lesions. The L/B ratio of osteolytic lesions with increased bone metabolism (11.82± 6?61) was lower than that of osteoblastic lesions (20.03±13.24) and that of mixed lesions (25.42±19.51;F=6.00, P<0?05) . The CT value of osteolytic lesions with increased bone metabolism was higher than that of osteolytic lesions with decreased bone metabolism :(167.53±79.21) HU vs (88.63±49.16) HU; t=3?345, P<0.05. The L/B ratio of lesions with increased bone metabolism was positively correlated to CT val?ue(r=0.404, P<0?05). Conclusions A part of lesions with increased bone metabolism on SPECT/CT im?ages are osteolytic lesions. The L/B ratio of them is positively correlated to CT value. SPECT/CT imaging can reduce missed diagnosis and misdiagnosis.

Objective To study the influence of valproate sodium(VPA)on neuroprotective effects of topiramate(TPM).Methods For-ty-eight 3-4 week-old male Wistar rats were randomly divided into 4 groups of 12 rats each.Group A was negative control rats,and groups B-D were rat model of epilepsy,induced by pentylenetetrazol(PTZ).The rats in 2 experimental groups were adminstered intragastrically with TPM 40 mg/kg and TPM 40 mg/kg+ VPA 200 mg/kg;2 control groups(groups A and B)with the equal amount of distilled water administration.After 2-month administration,changes of the behavior,levels of serum neuron-specific enolase(NSE)and the pathological in hippocampus were examined.Results The level of NSE in the group of TPM were significantly lower than that in masculine group,but no difference between masculine group and the TPM plus VPA.The pathological change in hippocampus were abatement in the group of TPM.Conclusion TPM plus high dosage of VPA will impaire the neuroprotective effects of TPM.
5. Stem cell therapy in stroke: Mechanism and progress in clinical research
Chinese Journal of Pharmacology and Toxicology 2019;33(2):81-92
Stroke is the leading cause of death and major cause of diability in China, but with few effective therapies. As few as 3%-5% of ischemic stroke patients have access to drug treatment with tissue plasminogen activators, and no drug treatment is available to patients of hemorrhagic stroke. Stem cell therapy has been proposed as a potential regenerative strategy for stroke patients. In the future, stroke stem cell research can be combined with genetic editing, 3D and other emerging technologies or drug treatments, to promote the development of stroke stem cell regenerative medicine. Based on the guidelines for stem cell research of stroke, this review elaborates on the action mechanism and clinical reasearch of stem cells for the treatment of stroke, including neural stem cells (human neural precursor cell line NT2/D1 and human immortalized neural stem cell line CTX) and adult stem cells (bone marrow mononuclear cells, mesenchymal stem cells, and multipotent adult progenitor cells), while disclosing the limitations of stem cell therapy. In the future, stem cell research in stroke can be combined with gene editing technology and drug treatment to improve the safety and effectiveness of stem cell therapy in the hope of promoting the research of regenerative medicine for stroke.

Objective To investigate the possibility of using well-differentiated human airway epithelial cells (HAE) to isolate and identify human influenza A virus from a stale respiratory tract specimen.Methods The stale specimen used in this study was a nasopharyngeal swab specimen collected from a patient with unexplained pneumonia in Qinghai in 2010.It was positive for influenza A virus (H3N2) RNA, but negative for hemagglutination.Equal amount of the specimen was inoculated on HAE and on Madin-Darby canine kidney (MDCK) cells for virus isolation and passage.Cytopathic effects were observed daily after inoculation.Hemagglutination inhibition test was performed at every passage.Electron microscope was used to observe viral morphology.Viral genome was sequenced, followed by molecular evolutionary analysis.Results No progeny virus was isolated in MDCK cells, while a influenza A virus subtype H3N2 strain [A/Qinghai/178/2010(H3N2)] was isolated in HAE with a typical morphology and cytopathic effect of influenza A infection.The hemagglutination inhibition activity was 1∶16.Results of the molecular evolutionary analysis of viral genome showed that the influenza A virus (H3N2) strain was highly homologous to the A/Nanjing/1655/2010(H3N2) strain, which was isolated during the 2010 influenza pandemic in Nanjing.Conclusion HAE can be used for isolation and identification of virus from stale respiratory tract specimens.It is more sensitive than MDCK cells with regard to human influenza virus isolation.

OBJECTIVE To observe the effects of glycogen synthase 3β (GSK-3β) in the regula-tion of NLRP3 inflammasome activation after acute myocardial infarction (MI) in Sprague Dawley(SD) rats. METHODS Ligation of the left anterior descending (LAD) in SD rats was used to establish an acute myocardial infarction model. SD rats were randomly divided into 3 groups (n=10, each group):sham group,MI group,and MI+SB group:the GSK-3β inhibitor(SB216763)was given 1 h by intrave-nous injection(0.6 mg·kg-1·d-1)before surgery.The serum and heart tissue were collected to measure lactate dehydrogenase (LDH) and IL-1β content and mRNA and protein levels of NLRP3, ASC, Cas-pase-1,IL-1β and GSK-3β after 2 days and 7 days operation,respectively.RESULTS The serum levels of LDH and IL-1β in the MI group were significantly higher than those in the sham group(P<0.01),and the MI+SB group was obviously lower than the MI group(P<0.01).In addition,mRNA and protein levels of NNLRP3, ASC, Caspase-1, IL-1β and GSK-3β expressions in MI group were clearly increased (P<0.01) compared with those in sham group.These indicators were significantly decreased in SB+MI group (P<0.01). Interestingly, the indicators were all higher at 7 days than 2 days. CONCLUSION GSK-3β inhibition induces cardioprotection via attenuating the activation of NLRP3 inflammasome after the acute myocardial infarction in rats.

The different biological functions were studied in mouse bone marrow-derived endothelial progenitor cells isolated by differential time attachment to obtain the optimal adherent time in this study. Density gradient centrifugation-isolated bone marrow mononuclear cells were seeded on the fibronectin-coated dish. The 1-day cultured unattached cells were seeded on the second dish for 2 more days. Then unattached cells in the second dish were seeded on the third dish. The cells on 3 dishes were defined as 1-day adherent cells, 3-day adherent cells and 3-day unattached cells, respectively. After 20-day culture, the biological functions, such as the percentage of biomarkers, the ability of adhesion, and the ability of forming tubes in vitro were analyzed. The results showed that the percentages of positive CD34, FLK-1, and CD34/FLK-1 expressions in 1-day attached cells were significantly increased compared to those in the 3-day adherent or unattached cells (P < 0.01), which showed the strongest adhesion ability. The expression of eNOS in 1- or 3-day adherent cells was significantly higher than that in 3-day unattached cells (P < 0.01). The expression of VEGF in 3-day adherent cells was significantly higher than that in 1-day adherent cells or 3-day unattached cells (P < 0.01). These results suggest the biological functions of 1-day adherent cells are significantly stronger than that of 3-day adherent or unattached cells. VEGF expression in 3-day adherent cells is higher than that in 1-day adherent cells or 3-day unattached cells. The expression of eNOS in 1-day adherent cells or 3-day adherent cells is higher than that in 3-day unattached cells. The optimal adherent time to obtain mouse bone marrow-derived endothelial progenitor cells is 1-3 d.

Chinese Acupuncture & Moxibustion 2014;34(7):721-724
ABSTRACT The taboos of man-spirit (RenShen) and bottom-spirit (KaoShen) are two kinds of time-related contraindications that are more commonly seen in the literature of acupuncture and moxibustion. The meaning of man-spirit is often extended to qi-blood or mind, or else directly equals to heaven-spirit (TianShen). It is highly possible that the bottom-spirit is subordinate to man-spirit, and both Taoist philosophy and the SanCai theory declare the importance of bottom in human body. The violation of contraindications could lead to diseases in the neighborhood where man-spirit travels. However, the results are generally recorded as ulcer, lingering disease and death in most medical texts. From Ming dynasty, more and more doctors have expressed disapproval of man-spirit and bottom-spirit.
