Objective To observe the dynamic changes of CPP32 mRNA in hippocampus following temporary whole cerebral ischemia in rats and to explore the mechanism of neuron apoptosis induced by cerebral ischemia.Methods The model of temporary whole cerebral ischemia in rats were induced by carotid artery negative pressure shunt and the expression of CPP32 mRNA were detected with fluorescence quantify RT PCR.Results Compared with the naive group, the expression of CPP32 mRNA did not increase insignificantly in sham operation group. Compared with sham operation group, the expression of CPP32 mRNA in ischemia group trended to increase at 6 h after ischemia and increased by 53% at 12 h and 223% at 24 h after ischemia. It kept in high level and decreased at 72 h after ischemia.Conclusion The expression of CPP32 mRNA in hippocampus could be induced by temporary whole cerebral ischemia. It began to increase at 6 h, reached its fastigium at 24 h and tended to decrease at 72 h after ischemia. The enhanced gene transcription of CPP32 plays an important role in the neuron apoptosis induced by cerebral ischemia.

OBJECTIVE:To evaluate the efficacy and safety of salmon calcitonin plus Xianling gubao for osteoporosis and ostealgia in postmenopausal women. METHODS:160 women with postmenopausal osteoporosis and ostealgia were randomized to 3 groups (treatment group and 2 control groups):the treatment group received(500 IU q.d) salmon calcitonin nasal spray plus Xianling gubao(1.5 g b.i.d orally); the control group Ⅰ received(500 IU q.d) salmon calcitonin nasal spray alone and the control group Ⅱ received Xianling gubao(1.5 g b.i.d orally) alone. All the patients received oral Caltrate D (1 tablet q.d). A course was defined as 30 days. After treatment for a total of 3 courses,the nature and degree of ostealgia in all the patients were assessed,and the outcome indexes were measured and the adverse drug reactions were recorded. RESULTS:There were significant differences between the treatment group and two control groups in total effective rates(92.59% for treatment group vs. 69.81% for control group Ⅰ and 67.92% for control group Ⅱ,P0.05). CONCLUSION:Treatment of osteoporosis and ostealgia in postmenopausal women with salmon calcitonin plus Xianling gubao has been proved to be safe and effective in that the bone density can be increased effectively and the osteoporotic pain of lumbar and back of the patients can be relieved.

Multiple myeloma is a neoplasm of mature and immature plasma cells, it remains an incurable disease using conventional chemotherapy and increasing aggressive approaches. In recent years, due to the better understanding of myeloma biology, genetics and tumor formation, there are lots of new active drugs or combinational chemotherapy regimens having been developed, such as proteasome inhibitors, immunomodulatory agents etc, they are more effective than conventional chemotherapy. This article summarizes the recent advances with the new options for the treatment of multiple myeloma.

Objective:To explore the correlation among risk factors of hypertension and waist-to-height ratio (WHtR) in officers of regiment and above in troops stationed in Zhejiang .Methods :A total of 2641 officers of regi-ment and above from troops stationed in Zhejiang ,who participated in annual physical examination in our hospital from 2012 to 2013 ,were selected .Correlation among body mass index (BMI) ,waist circumference (WC) ,WHtR , waist/hip ratio (WHR) and blood pressure were analyzed ;receiver operator characteristic curve (ROC) was used to compare and analyze the predictive value of above four indexes on hypertension and judge the optimal cut-off point . Results :(1) Pearson correlation analysis indicated that WHtR was positively correlated with WC ,BMI ,WHR ,sys-tolic and diastolic blood pressure (r=0.25~0.94 ,P<0.005~ <0.001);(2) Among above four indexes ,WHtR had the largest area under the ROC curve 0.697 (95% CI 0.676~0.718) and the optimal cut-off point was 0.51 ;and it's 0.651 (95% CI 0.639~0.662) for BMI ,0.689 (95% CI 0.664~0.751) for WC and 0.685 (95% CI 0.672~0.698) for WHR ;for morbidity risk of hypertension ,compared with BMI ,WC and WHR ,WHtR possessed the most balanced sensitivity (60.68% ) and specificity (70.74% ) ,and the largest OR 4.12 (3.71~4.59) .Conclusion:(1) Among officers of regiment and above in troops stationed in Zhejiang ,anthropometric indexes are closely relat-ed to blood pressure ,which can be regarded as simple indexes for predicting and assessing morbidity risk of the popu-lation ;(2) Waist-to-height ratio may be the best anthropometric index evaluating risk of hypertension in these popu-lation and its optimal cuf-off point is 0.51 for predicting hypertension .

Objective To investigate the correlation between vertical infection of hepatitis B virus(HBV) and Hofbauer cell in placenta.Methods Placental structural change,the correlation between HBV infection and Hofbauer cell in 14 vertical transmission cases(HBsAg and HBV-DNA seropositive in both mothers and their neonates),62 non-vertical transmission cases(HBsAg and HBV-DNA seropositive in mothers,but HBsAg and HBV-DNA seronegative in their neonates) and 10 controls(HBsAg and HBV-DNA seronegative in both mothers and their neonates) were determined by inmumohistochemical techniques and photomicroscopy.Results 1.necrosis,edema,villi capillary sclerosis,intravillifibrosis,fibrinoial sendimentation,morphokarrioleukocyet,lymphacyte,granulocyte were observed in placentas both vertical transmission cases and non-vertical transmission cases.2.Placental HBsAg postive rate in vertical transmission cases was 100%,but 58% in non-vertical transmission cases.There was significant difference in two groups(P=(0.013)).The positive sign was observed in trophoblast cell,Hofbauer cell and endothelial cell.3.Total Hobauer cell and ones combined with HBV in placentas of vertical transmission cases obviously increased(P

Objective To study the adjuvant effects of chitosan on Helicobacter pylori (H.pylori) vaccine.Methods A total of 20 adult mice were randomly divided into four groups.Mice in groups Ⅰ,Ⅱ,Ⅲ, and Ⅳ were orally immunized with PBS,H.pylori antigen alone,H.pylori antigen plus chitosan solution or H. pylori antigen plus chitosan particles,respectively.An ELISA was used to detect anti-H.pylori IgA in saliva and gastric mucosa ,interlukin(IL)-2,IL-4,IL-10 levels in gastric mucosa.Immunohistochemical method was used to detect secretory IgA in gastric mucosa.Results ①The levels of special anti-H.pylori IgA in saliva and gastric mucosa in the groups with chitosan as adjuvant were significantly higher than those in the group without adjuvants and control groups(P

DNA methylation is closely related to the genesis and development of glioma.The CpG islands hypermethylation in promoter region of DNA repair genes,cell cycle controlling genes,apoptosis related genes,tumor suppressor genes and invasion related genes are found in glioma.Finding the specific methylation profile and molecular marker of glioma is helpful for the pathology class,early diagnosis and prognostic evalua-tion.Meanwhile,DNA methylation has the characteristic of reversibility,which may provide new ways for the treatment of glioma.

Atherosclerosis is the most important cause of ischemic stroke. microRNAs can play an important role in the lipid metabolism, vascular inflammatory response, angiogenesis, as wel as smooth muscle cel proliferation and phenotypic conversion, etc. by regulating the functions of vascular endothelial cel s, vascular smooth muscle cel s, and mononuclear macrophages. It is closely associated with the occurrence and development of atherosclerosis. This article mainly reviews the regulatory effect of microRNAs on lipid metabolism and vascular inflammatory response in pathogenesis of atherosclerosis.
