AIM： To evaluate the prevalence and predictive factors of osteoporosis in patients with gastric adenocarcinoma alter gastrectomy.METhoDS： The study included 133 patients diagnosed with gastric adenocarcinoma but who did not undergo prior diagnostic work-up for osteoporosis. Bone mineral density （BMD） was measured by dual-energy X-ray absorptiometry （DXA） and vertebral deformity was assessed by plain X-rays. We evaluated the effects of age, sex, body mass index （BMI）, anemia, back pain, vertebral deformity, tumor staging, reconstruction type, and past medical history to determine predictive factors of osteoporosis in these patients.RESULTS： The prevalence of osteoporosis in the lumbar spine was 38.3% （male, 28.9%; female, 54.0%）, and 15.0% in the femoral neck （male, 10.8%; female, 22.0%）. The vertebral deformity rate was 46.6% （male, 43.4%; female, 52.0%）. Age, BMI and hemoglobin correlated with BMD （P 〈 0.01）. In males, anemia and age 〉 64 years were independent predictive factors of osteoporosis in multivariate analysis. In females, back pain was an independent factor for osteoporosis.CONCLUSION： The results of this study revealed that prevalence of osteoporosis and vertebral bone deformity rate were high in gastric cancer patients, regardless of post-gastrectomy duration and operation type. Early diagnosis and a proper management plan must be established in these patients.

Hemangioperioltoma is a rare tumor especially when it rises in the peritoneal cavity. We present a case of a 60-year-old woman with an isolated recurrent hemangiopericytoma of the liver. The patient presented with a palpable right upper quadrant abdominal mass, which occurred 7 years after undergoing resection of a malignant hemangiopericytoma arising from the greater omentum. She had not followed up 6 mo after surgery. Various imaging studies showed a single large, well-capsulated liver tumor with central necrosis, accompanied by hypervascularity typical of a vascular tumor. Preoperative laboratory HBsAg and anti-HCV workup were both negative. Under the impression of recurrent malignant hemangiopericytoma, right trisegmentectomy was performed to completely resect the tumor. Pathological examination confirmed the diagnosis of recurrent hemangiopericytoma. Even though the incidence of the hemangiopericytoma is relatively low, malignant hemangiopericytoma has a tendency to recur frequently after a long-term disease-free interval. Also, the recurrent hemangiopericytoma is not easily detected early during follow-up until it becomes symptomatic because there are no specific tumor markers, and because of the diversity with regard to site of recurrence. The authors suggest that Positron Emission Tomogram （PET） may be a useful tool for the detection of recurrent hemangioperioltoma. We describe herein some characteristics and behaviors of malignant hemangiopericytoma, particularly after surgical resection.

OBJECTIVE: To show whether Danggui Sini plus Wuzhuyu Shengjiang Tang(DSWST) has any transient effect on erythrocyte deformability in normal ***: A total of 25 subjects [mean age(27.8± 1.8) years] was enrolled in this study. The study was designed as a cross-over trial in which the subjects took part for 2 d. On the first day, blood samples were collected at baseline and 1-2 h after administration of water, whereas, on the second day, instead of water, the subjects were administered DSWST after the baseline blood sampling. The blood samples collected at baseline and after the administration water or DSWST, were examined for erythrocyte ***: The elongation index increased significantly after 2 h(P = 0.009) compared to the baseline after DSWST intake. however, after water intake, there was no significant differenceobserved. When comparing the percent change of erythrocyte deformability between DSWST and water, we found that after 2 h of administration,DSWST improved erythrocyte deformability significantly compared to water(P < 0.001).CONCLUSION: DSWST has a transient effect on erythrocyte deformability in normal subjects.

Objectives： Chunghyuldan （CHD）, a combinatorial drug that has anti-hyperlipidemic and anti inflammatory activities, has been shown to reduce infarct volume in a focal ischemia-reperfusion rat model. To explore the molecular basis of CHD＇s neuroprotective effect, we examined whether CHD shows a cell-protective activity and has a regulatory effect on Bax and/or B-cell leukemia/lymphoma 2 （Bcl-2） expression in mouse neuroblastoma 2a （N2a） cells subjected to hypoxia-reoxygenation （H/R）. Methods： In order to evaluate the effects of CHD on the cytotoxicity induced from hypoxia or H/R condition, lactate dehydrogenase （LDH） assay was performed. To explore whether the suppression of neural damage when pre-treated with CHD is associated with its anti-apoptotic effect, the CHD effect on the expression of Bcl-2 and Bax was analyzed by Western blotting analysis. Results： Cytotoxicity of N2a cell line was slightly increased in 42 h hypoxia condition and dramatically increased under the H/R condition. CHD treatment markedly decreased the cytotoxicity in both conditions （P〈0.01, P〈0.05）. H/R markedly increased the expression of the pro-apoptotic protein, Bax, but slightly increased the expression of the anti-apoptotic protein, Bcl-2, compared with the normoxia or hypoxia group. CHD significantly decreased Bax expression （P〈0.01） and slightly decreased Bcl-2 expression （P〉0.05）, resulted in a reduction of Bax/Bcl-2 ratio in N2a cells subjected to H/R. Conclusion： CHD has neuroprotective effect in N2a cells subjected to H/R, which might be derived at least in part from its ability to decrease the expression of the pro-apoptotic protein, Bax.

Objective： TO determine whether jaw-tapping movement, a classically described as an indication of personal well-being and mental health, stimulates the memory and the cognitive regions of the brain and is associated with improved brain performance. Methods： Twelve healthy right-handed female subjects completed the study. Each patient performed a jaw-tapping task and an n-back task during functional magnetic resonance imaging （fMRI）. The subjects were trained to carry out the jaw-tapping movement at home twice a day for 4 weeks. The fMRI was repeated when they returned. Results： During the first and second jaw-tapping session, both sides of precentral gyrus and the right middle frontal gyrus （BA 6） were activated. And during the second session of the jaw-tapping task, parts of frontal lobe and temporal lobe related to memory function were more activated. In addition, the total percent task accuracy in n-beck task significantly increased after 4 weeks of jaw- tapping movement. After jaw-tapping training for 4 weeks, brain areas related to memory showed significantly increased blood oxygen level dependent signals. Conclusion： Jaw-tapping movement might be a useful exercise for stimulating the memory and cognitive regions of the brain.
