Objective:To investigate the effects of genistein (Gen) on apoptosis in human osteoblast. Methods:Human periosteum was maintained in DMEM medium containing 10% newborn calf serum through four passages to isolate and proliferate osteoblast. Then, cells were maintained in phenol red-free DMEM supplemented with 5% charcoal-stripped FCS for 4 d before addition of treatments. Flow cytometer and DNA fragment were used to explore apoptosis in osteoblast, and immunohistochemistry was used to study protein expression of Bax, Bcl-2 and caspase-3. Results:Estrogen depletion could induce apoptosis in human osteoblast. With the similarity of 10-8 mol/L E2, at the conentrations of 10-6 mol/L and 10-5 mol/L, Gen could inhibit apoptosis induced by estrogen depletion. Compared with vehicle control, Gen significantly decreased protein expression of Bax and caspase-3 and increased protein expression of Bcl-2. Conclusion:Genistein could inhibit apoptosis induced by estrogen depletion in human osteoblast.

Background and purpose:Tumour cell is recognized and rejected by immunocytes.The local infiltration of immunocytes and the clinical curative effect after the percutaneous microwave coagulation therapy(PMCT) is worthy of further study.We investigated the local immune response after PMCT under ultrasound guidance and evaluated if the local immune response had any influence on the prognosis of patients.Methods:89 cases of patients with hepatocellular carcinoma were treated by PMCT.At the time of the fourth week after PMCT and before PMCT,the patients were given percutaneous biopsy under ultrasound guidance.And the samples were stained by immunohistochemical methods.Then the infiltration of CD4+、CD57+ and CD68+ of local treatment areas were compared before and after the treatment of PMCT.Meanwhile,the patients underwent follow-up to survey the possibility of recrudescence.Moreover,the authors analyzed the relation between the infiltration of immunocytes and recrudescence.Results:A few CD4、CD57 and CD68 positive cells were observed in the cancer stoma and tissues surroundings the liver before PMCT.After PMCT,the immunocytes of CD4、CD57 and CD68 positive cells were significantly increased both in the cancer and the adjacent liver tissue.These immunocytes were enlarged in size.The infiltration of CD4+、CD57+ and CD68+ increased significantly in post-PMCT as compared with those of pre-PMCT(P

Objective To study the macrophage immune response after the percutaneous microwave coagulation therapy (PMCT) under the ultrasound guide. Methods Eighty-nine cases of primary hepatic carcinoma patients were treated by PMCT. At the time of the fourth week after PMCT and before PMCT, the patients were given percutaneous biopsy under ultrasound guide. And the samples were stained by immunohistochemical methods. Then the infiltration of macrophage on local treatment areas were compared before and after the treatment. Moreover the function of immunocytes were observed by electronic microscope. Results The infiltration of macrophage increased significantly in post-PMCT as compared with that in pre-PMCT. And there were more protuberance from the macrophage and much more lysosome and endoplasmic reticulum and mitochondrium observed by electronic microscope. Conclusion The local macrophage cellular immunity can be more improved after the primary hepatic carcinoma treated by PMCT.

Objective To assess the value of multi-slice spiral CT angiography (MSCTA) in diagnosis of posterior nutcracker syndrome (NCS). Methods MSCTA of 15 patients clinically diagnosed as posterior NCS (patient group) and 50 subjects with normal renal vessels (control group) were retrospectively analyzed. The anatomy, course and relationship to the adjacent structure of left renal vein (LRV) and its branches were observed. The anteroposterior diameter (d1) and cross areas (s1) of the angle of control group and posterior abdominal artery (AA), the anteroposterior diameter (d2) and cross areas (s2) at the largest lumen near the renal hilar were measured and the ratio of s2/s1 and d2/ d1 were calculated.Results All LRVs posterior AA of patient group were compressed and narrowing with dilating apparently near the renal hilar. The difference of d2 was not significant (P>0.05), but of other values were significant (P<0.05).Conclusion MSCTA can show anatomy and three-dimentional trend clearly of LRV for posterior NCS, and evaluate the extent of narrow and dilating lumen accurately with cross areas measuring.

Objective To observe the therapeutic effects and comphcations of treatment by using transcatheter arterial chemombolization(TACE) combined with functional splenic embolization(FSE) on patients with primary hepatocelluar carcinoma (HCC) combinded with hypersplenism.Methods Eighty HCC patients with hypersplenism were randomly divided into two groups by computer program.Observation group was treated with TACE and FSE,while control group was treated by only TACE.The iodine oil deposition,blood routine parameters and related complications were observed.Results (1) After one-month' s treatment,abdominal CT scan showed that 38 cases(79.17%) of patients in the observation group and 27 cases (84.38%) of patients in control group had iodine oil deposition in over 50% of the tumor area.(2) The white blood cell counting in observation group were (7.65 ± 2.3) × 109/L,(5.89 ± 1.9) × 109/L,(5.02 ± 1.7) × 109/L in the follow-up examination 1 week,1month and 3 month after splenic embolization,respectively,which were significantly increased from the preoperative level of (2.21 ± 1.1) × 109/L(P < 0.05).Platelets counting were (93 ± 29)× 109/L,(127 ± 32) × 109/L and (119 ± 26) × 109/L in observation group at 1 week,1 month and 3 month after splenic embolization,respectively,which were significantly higher than the preoperative level of (39 ± 20)× 109/L (P < 0.05).In the control group,there were no statistically significant difference between the preoperative and postoperative levels (P > 0.05).(3) Both of the the two groups showed no serious complications.Conclusion TACE combined with FSE is a safe and an effective method to treat hypersplenism combined in HCC patients.

Objective:To investigate the current status of cognitive frailty among elderly patients in Urumqi and to identify its influencing factors.Methods:From March to December 2019, the elderly from 3 tertiary hospitals′ geriatrics centers in Urumqi were recruited using the general information questionnaire, FRAIL Scale, Montreal Cognitive Assessment and Clinical Dementia Rating.Results:A total of 1 006 elderly patients were surveyed, among which, 131(13.0%) cases were deemed to have developed cognitive frailty. The results of multivariate logistic regression analysis showed that age, depression, Instrumental Activities of Daily Living Scale score and diabetes were influencing factors of cognitive frailty ( P<0.001). Conclusion:The prevalence rate of cognitive frailty in elderly patients is relatively high. Medical staff should attach great importance to the assessment of cognitive frailty in elderly patients and take targeted intervention in time to prevent, slow down or reverse the onset and development of cognitive frailty.

Objective:To survey the status quo of awareness, demands and satisfaction of Traditional Chinese Medicine (TCM) service among the elderly residents in nursing home.Methods:A randomized survey on the status quo of TCM service was conducted from May to July 2019 among 237 elderly in 9 long-term care facilities close to a TCM hospital in Pudong New Area. The awareness, demands, satisfaction and influencing factors were analyzed.Results:Among 237 participants, only 1(0.4%)knew the TCM and its care well, however, 195 (82.3%) showed demands of TCM service. There were significant differences in the scores of demands and satisfaction of TCM among participants with different age, education level, marital status, medical insurance and health level ( P<0.05). Among the 16 TCM services, the three with top demand scores were acupoint massage (3.54±1.21), TCM health education (3.29±1.08), TCM drug iontophoresis (3.23±1.26); the three with top satisfaction scores were TCM health education (3.38±0.94), traditional health exercise (3.33±0.95), moxibustion (3.32±1.15). The demands and satisfactory were most correlated with each other in the guidance TCM medication ( r=0.996) and TCM herb tea ( r=0.988); and least correlated in the identification of TCM constitution ( r=0.305) and acupoint massage ( r=0.484). Conclusions:Among the elderly in long-term care facilities the awareness of TCM is at a low level, while the demands of TCM service are high. It is necessary to promote TCM service for elderly in long-term care facilities through TCM health education and developing the TCM products and appropriate techniques.
