Objective: To investigate the therapeutic effect of acupuncture plus hyperbaric oxygen in treating hypoxemic infantile encephalopathy (HIE). Methods: Fifty-nine HIE children were divided into treatment (33 cases) and control (26 cases) groups. Both groups were treated by basic therapy of removing acidosis, controlling cerebral edema and convulsion, and intravenous drip of cerebrolysin or citicoline. The treatment group was treated by acupuncture plus hyperbaric oxygen and the control group was treated by hyperbaric oxygen only. Results: The total effective rate was 97.0% in the treatment group and 73.1% in the control group. Statistical analysis showed a highly significant difference (P＜0.01). Conclusion: Acupuncture plus hyperbaric oxygen was better than simple hyperbaric oxygen in treating HIE. Its main manifestations were shortening the course of disease, increasing cure rate, decreasing death rate and reducing the occurrence of sequelae.HIE children should be treated as early as possible.

To study the influence of foreign plasmid DNA on spleen metabolism in immune-stimulated mice via the gastrointestinal tract. Mice were oral administered by pipette with 200?g of plasmid pcDNA3 and spleen were isolated at 4h and 18h after oral administration. Total RNA were extracted from spleen and spleen gene expression profile of Balb/c mice was analyzed by using Affymetrix oligonucleotide genechip after oral plasmid pcDNA3 administration. Functional cluster analysis was conducted by Genmapp and MAPPFinder software. By functional cluster analyzing the genes which were up-regulated more than twofolds, Genmapp results showed that plenty of metabolic pathway were induced in spleen after oral administration of plasmid pcDNA3. These metabolic process included purine metabolism, pyrimidine metabolism, protein synthesis, cholesterol synthesis, fatty acid synthesis, Glycolysis, TCA cycle and mitochondria oxidative phosphorylation pathway. The similar results also took place at 18h after oral administration. The result indicated that foreign plasmid DNA can modulate metabolism process in spleen of mice via the gastrointestinal tract, and may help understand the mechanism of action of foreign plasmid DNA uptaked via the gastrointestinal tract.

Objective To explore the effects of Buyang Huanwu decoction(BYHWD)on expressions of nuclear factor-κB p65(NF-κBp65)and its inhibitor( I-κB)in signal transduction of NF-κB in brain tissue of rats with focal cerebral ischemia injury. Methods 180 Sprague-Dawley(SD)rats were randomly divided into normal group,sham-operated group,model group,pynolidine dithiocarbamate(PDTC)group,minocycline(MC)group and BYHWD treatment group,each group 30 rats. The rats of PDTC group were given PDTC 100 mg?kg-1?d-1 by intra-peritoneal injection. In MC group,MC was given by filling the stomach,the dose was 2.35 g?kg-1?d-1,the drug solution was prepared by adding the distilled water,and the total volume of drug solution to fill the stomach was kept at the same volume in various groups,thus the concentration of the drug was different. In BYHWD group,BYHWD was given,the dose was reduced to 5 g?kg-1?d-1 according to the body surface area dose conversion formula about people and animals. In sham-operated group and model group,the distilled water was given in the same volume as other drug solution. The protein expression levels of NF-κBp65 and I-κB in ischemic tissues were examined by using immunohistochemical method on the time points 7,14 and 21 days after treatment in each group. Results Compared with model group, the cell numbers with expression of NF-κBp65 in PDTC group,MC group and BYHWD group were significantly decreased along with the prolongation of therapy time,the decrease in number was more and more,until 21 days,it reached the valley level(cell/400 times HP:44.00±6.91,45.33±6.55,18.67±2.14 vs. 126.00±5.78,all P<0.05);the number of cells with expression of I-κB was obviously increased,the differences being statistically significant(all P<0.05),but the differences in expression of NF-κBp65 among the treatment groups at the different time points were not statistically significant(all P>0.05). After treatment for 7 days,the number of cells with positive expression of I-κB protein in BYHWD group was less than that in MC group(cell/400 times HP:55.00±3.40 vs. 72.50±4.29,P<0.05);after treatment for 14 days,the number in BYHWD group was approximately the same as that in the MC group, the difference being not statistically significant(93.50±6.15 vs. 93.00±6.20,P>0.05),and after treatment for 21 days,the number in BYHWD group was significantly higher than that in MC group(88.83±4.95 vs. 71.17±7.16, P<0.05). Conclusion BYHWD can regulate the expressions of inflammatory cytokine I-κB and NF-κB in signal transduction of NF-κB in ischemic brain tissue to inhibit the inflammatory reaction,thus it has the protective effect on cerebral ischemia.

BACKGROUND: Hallux valgus is a common orthopedic disease, and its causes are complex and treatment is varied. The mechanical analysis of hallux valgus is an issue of concern. The finite element analysis makes it predictable to treat hallux valgus. OBJECTIVE: To explore the clinical application of finite element analysis in biomechanical study of hallux valgus.METHODS: The first author searched CNKI and PubMed databases from January 1980 to March 2017 using the key words of "finite element, hallux valgus" in English and Chinese, respectively. The repetitive, irrelevant and low-quality articles were excluded. Finally 33 eligible articles were included in accordance with the inclusion criteria, and the critical issues of finite element analysis applied in hallux valgus were reviewed. RESULTS AND CONCLUSION: (1) There are many researches concerning finite element of hallux valgus, which mostly require physicians to work with engineers. These methods are already very mature, but most of the model and material properties of the data come from foreign researches. (2) The finite element analysis is important and reliable for the etiology of hallux valgus, preoperative planning and prognosis. (3) The finite element model of the hallux valgus is only used on static analysis and gait cycle analysis, the modeling details and definition of material properties still need to be improved.

Objective To study the clinicopathologic features of brain tumors in patients with medically intractable epilepsy. Methods The clinical, radiologic and pathologic features of brain tumors in thirty-six patients with intractable epilepsy encountered during the period from 2008 to 2014 in the Epilepsy Center of Haidian Hospital were retrospectively reviewed. Results There were 18 males and 18 females in thirty-six patients. The mean age of seizure onset and disease duration were (14.05 ± 1.67) years and (10.04 ± 1.19) years respectively. The histological types of brain tumors included ganglioglioma (12/36, WHO gradeⅠ,1/36, WHO gradeⅡ), dysembryeplastic neuroepithelial tumor (2/36, WHO gradeⅠ), pleomorphic xanthoastrocytoma (1/36, WHO gradeⅡ), angiocentric glioma (1/36, WHO gradeⅠ), astrocytoma (4/36, WHO gradeⅡ), oligoastrocytoma (1/36, WHO gradeⅡ, 2/36, WHO gradeⅠ-Ⅱ), oligodendroglioma (1/36, WHO gradeⅠ-Ⅱ,1/36, WHO grade Ⅱ), cavernous hemangioma (4/36) and Sturge-Weber syndrome (1/36). Most of these tumors were located in temporal lobe (25/36, 69.4%). Patients were followed up for 0.5-7 years after operation. One patient was lost for follow up. Seizure outcome after the epilepsy operation revealed that 28 patients (77.8%) had Engel gradeⅠ, 4 patients (11.1%) had Engel gradeⅡ,2 patients (5.6%) had Engel gradeⅢ,1 patient (2.8%) had Engel gradeⅣ. Conclusion Brain tumors in patients with medically intractable epilepsy are almost low grade tumors of the nervous system. Focal cortical dysplasia is existed in most brain tissues from the epilepsy operation. Low grade tumors of the nervous system have close relation with focal cortical dysplasia in patients with medically intractable epilepsy. It is possible that the classifications of pathology diagnosis has connection with prognosis.

BACKGROUND: Oral inflammatory diseases usually cause alveolar bone loss and odontoseisis, and further impact dental occlusion. Extracorporeal shock wave therapy (ESWT) is a promising method for the repair of alveolar bone and improving osteogenic activity of alveolar osteoblasts, but its therapeutic efficacy and related mechanisms remain unclear. OBJECTIVE: To compare the effect of different intensities of ESWT on the proliferation and osteogenesis abilities of rat alveolar osteoblasts. METHODS: The rat alveolar osteoblasts were obtained and cultured in vitro, and further identified by alkaline phosphatase staining. 0.18, 0.36, and 0.50 mJ/mm2 ESWT was used to stimulate the rat alveolar osteoblasts, 100 pulses, respectively. RESULTS AND CONCLUSION: The levels of alkaline phosphatase and bone morphogenetic protein 2 were significantly increased in the 0.36 and 0.18 mJ/mm2 ESWT groups, especially in the 0.36 mJ/mm2 ESWT group (P < 0.05). 0.50 mJ/mm2 ESWT significantly decreased the proliferation ability of rat alveolar osteoblasts and downregulated the levels of alkaline phosphatase and bone morphogenetic protein 2 (P < 0.05). To conclude, ESWT (< 0.36 mJ/mm2) can improve the osteogenesis ability of rat alveolar osteoblasts with the intensity increasing, which provides a theoretical basis for the clinical use of ESWT in the alveolar bone repair.

ObjectiveTo systematically evaluate the value of contrast-enhanced endoscopic ultrasonography (CE-EUS) in the differential diagnosis of mass-type chronic pancreatitis and pancreatic cancer. MethodsCNKI, Wanfang Data, CBM, PubMed, Embase, and the Cochrane Library were searched for Chinese and English articles on the value of CE-EUC in the differential diagnosis of mass-type chronic pancreatitis and pancreatic cancer published up to December 31, 2018. Secondary screening, scoring, and data extraction were performed, and then Meta-Disc1.4 and stata12.0 software were used for meta-analysis. ResultsA total of 20 articles with 1888 patients were included in this study. The meta-analysis showed that in the differential diagnosis of mass-type chronic pancreatitis and pancreatic cancer, CE-EUS had a pooled sensitivity of 86% (95% confidence interval ［CI］: 83%-89%), a specificity of 93% (95%CI: 92%-95%), a positive likelihood ratio of 12.01 (95%CI: 9.72-14.85), a negative likelihood ratio of 0.16 (95%CI: 0.10-0.26), a diagnostic odds ratio of 76.12 (95%CI: 54.50-106.31), and an area under the summary receiver operating characteristic curve of 0.965 5. No sources of heterogeneity were found in the threshold effect test, the meta-regression analysis, and the sensitivity analysis. After the four articles causing heterogeneity were excluded, the heterogeneity of all included articles was reduced to an acceptable range, and there were no significant changes in the results of the meta-analysis. ConclusionCE-EUS has a good value in the differential diagnosis of mass-type chronic pancreatitis and pancreatic cancer, and its application in clinical practice can improve the diagnostic rate of pancreatic cancer.

Objective To study the doses and methods of F1 antigen(F1Ag) to immune Balb/c mice during the establishment of hybridoma cell strains. Secreting McAbs against F1Ag of Yersinia pestis. Methods Balb/c mice of seven to nine weeks old were randomly divided into six groups. The first four groups were 150, 100, 50 and 25 μg F1Ag inoculated group, having multipoint hypodermic inoculation of F1Ag of 150, 100, 50 and 25 μg followed by multipoint hypodermic inoculation of F1Ag of 100 μg for a second time and then intraperitoneal injection of 100 μg. Next, hypodermically inoculated group received F1Ag of 100 μg for three times in multiple points. Finally, the intraperitoneal injection group was intraperitoneally inoculated with F1Ag of 100 μg for three times. Emulsification liquid of F1Ag + Complete Frednd's adjuvant(CFA) of equivalence was used in the first inoculation, emulsification liquid of F1Ag + Incomplete Frednd's adjuvant(IFA) balanced mix in the second, F1Ag liquid in the third. One week afterwards, tail blood of the mice was collected to test antibody titers of anti-F1Ag by double antigens sandwich enzyme linked immunosorbent assay (DAgS-ELISA) and trace indirect hemagglutination assay(IHA). Results The levels of antibody of anti-F1Ag in 150,100,50 and 25 μg groups had statistics difference (DAgS-ELISA method: G = 12 173.87,13 440.37,15 024.19 and 4466.72, F= 3.11, P< 0.05;IHA: G = 19 972.32,18 089.40,23 170.47 and 4871.08, F = 4.11, P < 0.05). Immune effect of the 3 groups of 150, 100 and 50 μg was almost the same (P> 0.05), and excelled as compared with that in 25 μg group with statistics difference(DAgS-ELISA method: t = 2.18,2.39,2.73, P < 0.05;IHA: t = 2.54,2.73,3.13, P< 0.05). The titer of F1 antibody had an increasing trend from the 100 μg group to hypodermic group and intraperitoneal injection groups, but without statistics difference (DAgS-ELISA method: G = 8933.44, 9986.16, 13 440.37;IHA: G = 13 777.25,16 384.00, 18 089.40, F = 0.66,0.25, all P > 0.05). Conclusions Hyodermical inoculation of F1Ag with the first dose of 50 μg in multiple points for mouse is appropriate, and a strengthening dose of 100 μg in an intraperitoneal injection may shorten the immune period.
