Objective To investigate the therapeutic effect of autologous stem cell transplantation research for patients with cerebral hemorrhage sequelae under the stereotactic.Methods One hundred patients with cerebral hemorrhage from Jan.2011 to Sep.2013 in our hospital were selected and randomly divided into the experimental group (n =50) and the control group (n =50).The patients of experimental group were given autologous stem cell transplantation under the stereotactic in 6 months after cerebral hemorrhage,while the patients in control group were just given traditional treatment.At 6,7 and 12 months after cerebral hemorrhage,rate with neural function defect scale and functional independence measure(FIM) scores of the two groups were compared.Results FIM scores in the experimental group was 102.08 ± 8.28,significant higher than that in control group(95.28±8.75,P＜0.05).Functional independence measure scores in the experimental group at 7 months after cerebral hemorrhage was 13.12±4.00,significant lower than that in control group(20.40±4.33,P ＜0.05).While,there was no statistical difference at 6 months and 12 months after cerebral hemorrhage between the two groups(P＞0.05).Conclusion The therapeutic of autologous stem cell transplantation on patients with cerebral hemorrhage sequelae under the stereotactic is benefit at short term,but the long term therapy effective still needs further study.

Objective To observe the anti-inflammation effect of antidromic electronic stimulation of rat dorsal roots. Methods Cross-excitation between adjacent primary afferent fibers and subcutaneous injection of 2% FM were adopted here as two inflammatory models. The firing rate and mechanical threshold of single units after cross-excitation were collected. The phosphorylated cAMP response element binding protein (p-CREB) level in spinal cord induced by formalin was visualized with immunohistology. Results Antidromic electronic stimulation (ADES) of dorsal roots could significantly inhibit the p-CREB over expression to FM injected in the contralateral hindpaw, and the increase in firing rate and mechanical threshold induced by cross-excitation were also inhibited by the ADES. Conclusion Antidromic electronic stimulation of the dorsal root may produce a systemic anti-inflamma-tion capacity.

Objective To investigate the influence of CO2-insufflation pressure on invasion potential of the colon cancer cells.Methods With an in vitro artificial pneumoperitoneum model,SW1116 human colon cancer cells were exposed to CO2-insufflation of 5 different pressure groups:6,9,12,15 mm Hg and control group,respectively for 1 h.The invasion capacities of SW1116 cells exposed to CO2-insufflation of 5 different pressure groups were detected by cell adhesion/invasion assay in vitro.Results Immediately following exposure to 15 mm Hg CO2 insufflation,the invasion of SW1116 cells decreased significantly compared to the cells before exposure.At the 0 h time point,the cells exposed to 15 mm Hg were significantly less invasive than those exposed to the other insufflation pressure(P

AIM: To observe the influence of Ganoderma lucidum spores on the cytokine IL-1? and c-Fos in the brain tissue of epilepsy rats. METHODS: The IL-1? level was examined by radioimmunoassay and the c-Fos expression was measured by immunohistochemical assay. RESULTS: Comparing the Ganoderma lucidum spores group with the epilepsy model group: c-Fos positive cell count in brain cortex and hippocampus in treatment group was obviously reduced. IL-1? level in brain tissue was also reduced obviously. CONCLUSION: Ganoderma lucidum spores effectively reduces cytokine IL-1? in brain tissue of epilepsy rats, improves the immunity dysfunction and plays a role in anti-epilepsy through suppressing c-Fos expression in epilepsy rats brain tissue and blocking of LRG.

Objective:Based on the occupational cohort of Beijing Medical Examination Center, to explored the relevant factors of nonalcoholic fatty liver disease (NAFLD), and to provide scientific basis for screening and early diagnosis of NAFLD in high-risk population.Methods:Based on the cohort of occupational population who underwent physical examination in Beijing physical examination center from January to December 2009, the physical examination indexes were collected, and a retrospective survival cohort with a follow-up period of 3 years was established.According to the idea of nested case-control study, each case was randomly matched with the same gender, age and physical examination time in the same month by using the method of random sampling without putting back.Conditional logistic regression model was established by using the matched data.The diagnostic value of related indicators for NAFLD was analyzed by receiver operating characteristic curve (ROC).Results:A total of 1 194 subjects were included, including 684 males (57.3%, 684/1 194) and 510 females (42.7%, 510/1 194). The age was (50.8±11.6) years.The age ranged from 24.0 to 88.0 years.There were 597 patients with NAFLD, including 342 males and 255 females.Logistic regression analysis showed that body mass index, high density lipoprotein cholesterol, hemoglobin, platelet count, uric acid and urea nitrogen were statistically significant in male model (all P<0.05). Body mass index( OR=1.242, 95% CI 1.143-1.349, P<0.001), hemoglobin( OR=1.034, 95% CI 1.015-1.053, P<0.001), platelet( OR=1.005, 95% CI 1.002-1.009, P=0.005), uric acid( OR=1.004, 95% CI 1.001-1.006, P=0.004), high density lipoprotein cholesterol( OR=0.377, 95% CI 0.184-0.775, P=0.008) and urea nitrogen( OR=0.807, 95% CI 0.693-0.938, P=0.005) were protective factors for NAFLD in male patients..Body mass index( OR=1.552, 95% CI 1.366-1.762, P<0.001), triglyceride ( OR=2.606, 95% CI 1.616-4.204, P<0.001), blood glucose( OR=2.199, 95% CI 1.332-3.631, P=0.002), uric acid( OR=1.005, 95% CI 1.001-1.010, P=0.024) in female model were statistically significant ( P<0.05), and were risk factors for NAFLD in female patients. Conclusion:The incidence rate of NAFLD was different among different gender and age, body mass index, high density lipoprotein cholesterol, hemoglobin, platelet count, uric acid, urea nitrogen, triglyceride and blood glucose were closely related to the incidence of NAFLD.

Objective To study the effect of intratumor angiogenesis and vascular growth factor(VEGF), basic fibroblase growth factor(bFGF), Platelet-derived growth factor (PDGF), and their receptors(flt-1 bFGFR.PDGFR) on the invasion, metaslasis of pancreatic carcimoma(PC) and the relationship between the expressions of three kinds of angiogenic factors, their receptors and microvessel count(MVC). Methods Tis- sue sections of 51 PC and 32 acute or chronic pancreatitis were examined by in situ hybridization for the expression of VEGF bFGF.PDGF, and by immunohistochemistry for the expression of the three kinds of angiogenic factor receptors and MVC.

Objective To introduce a novel femoral distractor which is applied in close reduction and internal fixation (CRIF) with antegrade intramedullary nail for femoral shaft fractures.Methods From September 2010 to March 2015,85 patients with femoral shaft fracture were treated by CRIF with antegrade intramedullary nail in which our self-designed novel distractor was used.They were 64 males and 21 females,with an average age of 36.6 years.By AO classification,we had 32 cases of type 32-A,40 cases of type 32-B,and 13 cases of type 32-C.The intervals between injury and surgery averaged 7.5 days (range,from 1 to 16 days).The fracture was located at the upper shaft in 26 cases,at the middle shaft in 57 cases,at the middle shaft and ipsilateral neck in one,and at the lower shaft and ipsilateral intertrochanteric site in one.Their operation time,intraoperative blood loss,intra-and post-operative complications,and fracture union time were recorded and analyzed.Results Successful close reduction was achieved in all the 85 patients with no iatrogenic injury to major vessels or nerves.Operation time averaged 105.5 minutes;time for X-ray exposure averaged 25.8 seconds;intraoperative blood loss averaged 209.2 mL.The 85 patients received follow-ups from 8 to 24 months (mean,16.3 months).Fracture union was achieved in 83 cases after an average duration of 7.8 weeks (range,from 4 to 12 weeks),but nonunion occurred in 2 cases.One-year follow-ups revealed recovery of normal function of the affected knee in all,with no limb shortening ＞ 10 mm,rotational angulation ＞ 15°,or lateral or anteroposterior angulation ＞ 10°.No incision infection,deep vein thrombosis or pulmonary embolism happened during the entire follow-up.Conclusion Our self-designed novel distractor can facilitate CRIF with antegrade intramedullary nail for femoral shaft fractures,and avoid the complications and inconvenience associated with a traction table.

Objective To investigate the influence of CO_2-insufflation on the expression of some adhesion molecules.Methods With an artificial pneumoperitoneum model in vitro, SW1116 colon carcinoma cells were exposed to CO_2-insufflation at different pressure (6, 9, 12 and 15 mmHg) for 1 hour. Control groups were exposed to room air. E-cadherin, ICAM-1, E-selectin, CD44 and CD44v6 were measured 0, 12, 24, 48 and 72 hours after CO_2-insufflation using flowcytometry and the mRNA level of these adhesion molecules were detected by real-time PCR.Results In transcription level the expression of ICAM-1 and CD44v6 on SW1116 cell line increased significantly in 6mmHg CO_2-insufflation group, in 9mmHg and 12mmHg group, E-cadherin,CD44 and CD44v6 increased significantly, and when the pressure was 15mmHg, CD44v6 increased (P

Objective To evaluate whether S-100β protein could be a serum marker for traumatic spinal cord injury (SCI). Methods From June, 2013 to October, 2014, 24 patients with complete SCI were measured the serum S-100β protein concentrations with en-zyme-linked immunosorbent assay, one week, three and six months after SCI. Serum from ten healthy persons was as normal control. Re-sults The serum S-100βprotein concentrations increased one week and 3 months after SCI (Z>4.273, P<0.001). Conclusion The increase of serum S-100βprotein may help assessing early impairment after complete SCI.

Objective:To analyze the effect of home quarantine on blood glucose and lipids in healthy adults during the COVID-19 epidemic times.Method:From April 7, 2020 to May 1, 2020, 512 adults wereexamined in Beijing physical examination center, of which 87 adults aged olderthan 18, received community closed management or home quarantine from January 23, 2020 to March 30, 2020, and theadultshad physical examination in Beijing physical examination center in the same month of 2018 and 2019 were selected as controls. The change trend of blood glucose and blood lipid acrossthe three years was analyzed by one-way repeated measurement of variance, and the difference of blood lipid and blood glucose between two years of physical examination was further analyzed by Bonferroni method. Datawereanalyzed by gender.Result:Among the 87 subjects, 36 (41.4%) were male and 51(58.6%) were female. The average age was (46.3±13.2) years and ranged from 24 to 74. The difference of high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), triglyceride (TG), total cholesterol (TC) and fasting blood glucose (FBG) among 2018, 2019 and 2020 was statistically significant (all P<0.05), while differences in LDL-C, TC and FBG were statistically significant for males (all P<0.05) and HDL-C, LDL-C, TC and FBG were statistically significant for females (all P<0.05). HDL-C in 2018and 2020were significantly lower than that in 2019 [(1.27±0.29), (1.30±0.31) vs. (1.36±0.34) mmol/L], LDL-C in 2020was significantly higher than that in 2018and 2019 [(3.11±0.88) vs. (2.81±0.77), (2.84±0.71) mmol/L], TG in 2020 was significantly higher than that in 2019[(1.54±1.17) vs. (1.32±0.80) mmol/L], TC in 2019and 2020were significantly higher than that in 2018 [(4.88±0.94), (5.10±0.99) vs. (4.63±0.90) mmol/L], and the FBG in 2019and 2020were significantly lower than that in 2018 [(5.34±1.17), (5.44±1.58) vs. (5.84±1.70) mmol/L] (all P<0.05). The comparative analysis of men and women showed that the means of LDL-C, TG, TC and FBG of men were higher than those of women while the mean of HDL-C was lower than that of women in each year; compared with 2019, the increase of LDL-C and TC of men was obvious while the decrease of HDL-C of women was obvious (all P<0.05) in 2020. Conclusion:During the epidemic period of COVID-19, the home quarantine has adverse effects on blood glucose and lipid.
