OBJECTIVETo explore incidence rate, influencing factors, leakage routes,and preventative measures of bone cement leakages in vertebral internal reinforcement operation including percutaneous vertebroplasty and percutaneous kyphoplasty.

METHODSFrom January 2010 to January 2012,94 patients with osteoporotic vertebral compressive fracture,vertebral metastases and vertebral hemangioma were treated by vertebral internal reinforcement operation. Among them, there were 39 males and 55 females aged 55 to 86 with an average of 69.4 years old. The reasons, types, incidence and complications of bone cement leakage were analyzed.

RESULTSTotally 21 patients (26 vertebral) occurred bone cement leakage, the main routes included basivertebral veins, and bone cortex, which mainly located on adjacent intervertebrae and around vertebral body, and most of them were asymptomatic leakage. For the treatment of OVCFs, incidence of bone cement leakage in PKP was lower than that of PVP (P < 0.05), while incidince of PVP in treating vertebral metastases was worse than in treating OVCFs (P < 0.05).

CONCLUSIONBone cement leakage is a common complication in PVP and PKP. Careful analysis before operation, cautiously monitors and grasp operation indication in operation can decrease incidence of it.

Objective To observe effects of ganoderma lucidum triterpenoids(GLT) on learning and memory function and anti-oxidative ability of aging model mice induced by D-galactose. Methods Senile model mice were established by D-galactose hypodermic injection for 8 weeks.GLT had been administered to two therapy groups.All the mice of different groups were tested with Morris water maze.Then the mice were killed and biochemically assayed of total anti-oxidative capacity(T-AOC),superoxide dismutase(SOD) and malondialdehyde(MDA) in the brain. Results The model mice showed worse ability in learning and memory in comparison with control mice.The T-AOC activity and SOD activity in the brain decreased and the MDA content increased in model rats in comparison with control.GLT significantly improved the changes mentioned above. Conclusion GLT improved the learning and memory dysfunction in aging model mice by modulation of the anti-oxidative ability.

Objective To compare the infectivity between laboratory adapted human inununodefi- ciency virus(HIV-1) and primary HIV-1 isolates for different mucosal epithelial cell lines. Methods Mu-cosal epithelial cells Caco-2, T-84, HeLa and lymphocyte MT-4 were infected with laboratory adapted HIV-1 SF33 and 2 primary HIV-1 isolates (02010561, 02010141). Culture supernatant and cells were collected respectively on 3-4 days interval after virus inoculation. The former was tested for HIV-1 antigen P24 level and viral load, and the latter was tested for total viral DNA and integrated viral DNA. Results All 3 virus strains could infect MT-4 cells and integrate into their genome. Only HIV-1 SF33 could infect Caco-2 cells but could not integrate into their genomic DNA. Both HIV-1 SF33 and 02010561 infected HeLa cells but only integration of HIV-1 SF33 was detected. All the 3 HIV-1 strains infected T-84 cells but only the integra-tion of HIV-1 SF33 and 02010141 was observed. Conclusion Although laboratory adapted and primary HIV-1 strains are able to infect human mucosal epithelial cell lines, transient or productive infection estab-lished in different mucosal epithelial cells is dependent on the character of cells and virus strains.

OBJECTIVETo compare the efficacy difference in the treatment of functional dyspepsia between acupuncture at the acupoints selected by pattern/syndrome differentiation and domperidone.

METHODSSeventy cases were randomized into an acupuncture group (35 cases) and a western medication group (35 cases). In the acupuncture group, Zusanli (ST 36) and Neiguan (PC 6) were selected. Taichong (LR 3) and Neiting (ST 44) were added for excess syndrome while Gongsun (SP 4) and Yinlingquan (SP 9) were added for deficiency syndrome. A pair of electrodes was attached to one acupoint and an assistant point (2 mm next to the acupoint centripetally) and stimulated with disperse-dense wave at 2 Hz/100 Hz, once a day. In the western medication group, domperidone was prescribed for oral administration, 10 mg each time, three times a day. In the two groups, the treatment of 5 days made one session and 4 sessions were required totally. Nepean dyspepsia index (NDI) was compared after treatment, 1, 2, 3, 4 and 5 months after treatment between the two groups respectively.

RESULTSThe score of symptom and score of life quality in NDI after treatment and at each follow-up time point were improved obviously in the acupuncture group as compared with those before treatment (all P < 0.01). In the western mediation group, the score of symptom and the score of life quality in NDI after treatment and in follow-up of 1, 2 and 3 months were improved obviously as compared with those before treatment (all P < 0.01), but the differences were not significant in follow-up of 4 and 5 months (both P > 0.05). Compared with the western medication group, the symptom score of NDI was reduced obviously after treatment and in each time point of follow-up in the acupuncture group (P < 0.05, P < 0.01), and the score of life quality was increased obviously (P < 0.05, P < 0.01).

CONCLUSIONAcupuncture at the acupoints selected by pattern/syndrome differentiation and domperidone are effective in the treatment of functional dyspepsia. Domperidone is unsatisfactory in the long-term effect, but acupuncture achieves the positive short-term and long-term effects on functional dyspepsia.

Background and purpose: L-asparaginase (L-Asp) is an important drug in the treatment of childhood lymphoid neoplasms at present, but a lot of adverse reactions of L-Asp were observed. Pegasparaginase (PEG-Asp) is available in China in recent years. This study aimed to explore efifcacy and side-effect of PEG-Asp as ifrst-line treatment in childhood acute lymphoblastic leukemia (ALL) and lymphoblastic lymphoma (LBL). Methods:A total number of 211 ALL or LBL patients were treated with CCLG 2008 or BFM-90 protocol with PEG-Asp or L-Asp between Apr. 2008 and Mar. 2013;42 patients, among whom, were 35 ALL patients and 7 LBL patients, were treated with PEG-Asp as ifrst-line treatment;169 patients were treated with L-Asp as ifrst-line treatment (including 53 patients treated with L-Asp during induction protocol; with PEG-Asp during consolidate protocol). The clinical outcome and adverse reaction of PEG-Asp with L-Asp were observe and compared. Results: There were 35 ALL patients in PEG-Asp ifrst-line treatment group and the complete remission rate after 1 course of PEG-Asp was 97.1%,however, which was 83.3%of high risk ALL patients. The complete remission rate of 7 LBL patients of PEG-Asp ifrst-line treatment group was 57.1%. There was no signiifcant difference between 2 groups (P>0.05). Thirty-four patients relapsed including 5 patients of PEG-Asp ifrst-line treatment group, 16 patients of L-Asp ifrst-line treatment group and 13 patients treated with L-Asp during induction protocol and with PEG-Asp during consolidate protocol. Thirty-one patients died including 3, 18, 10 patients in 3 groups respectively. Twenty-two patients died of relapse, 4 died without remission, 5 died of complications. There was also no signiifcant difference between 2 groups (P>0.05). The incidence rates of adverse reactions were 47.6% and 63.3% respectively. Anaphylaxis, liver functions abnormalities, blood coagulation abnormalities, gastrointestinal reaction, hyperglycemia and pancreatitis were common in our patients. The incidence rate of anaphylaxis in PEG-Asp as ifrst-line treatment group was lower than other groups (P=0.03). But there was no signiifcant difference been observed in the incidence of other adverse reaction. Conclusion: The short-term efifcacy of PEG-Asp as the ifrst-line treatment in childhood leukemia and lymphoma was satisfactory and the incidence rate of anaphylaxis was lower. However, we will still pay much attention to adverse reaction monitoring of PEG-Asp.

Objective To investigate the effect of low frequency electric deep brain stimulation on amygdale kindling in rats.Methods The amygdale kinkling model of rats was established by operation on the brain.The effects of low frequency deep brain electric stimulation used alone or in combination with anti-epilepsy drugs were ob- served in terms of severity of seizure attack reflected by Racine's scale and afterdischarge duration recorded in electro- encephalogram.Results Fifteen minutes of low frequency electric stimulation at 1 Hz and 100 to 350?A effective- ly inhibited amygdale kindling as demonstrated by a significant decrease of afterdischarge duration,and decreased the severity of seizure attack (P

Objective To probe the effects of nuclear factor kappa B (NF-?B) on cell apoptosis and left ventricular segmental function in acute ischemia repeffusion in dogs.Method Twenty-four dogs were randomly divided into three groups:without left anterior artery (lAD) ligation group (C group),LAD was occluded 30 min following reperfusion 120 minutes in isehemical reperfusion group (IR group),and dogs were administered with PDTC before LAD ligation in ischemical reperfusion plus pyorrole dithitocarbamate group (PDTC group).The left ventricular segmental function was detected by echo cardiography using strain rate anlysis software.EF measured by Simpson's method.Cardiac myocyte apoptosis numbers were determined by terminal deoxynudeotidy transferease-mediated biotinylated deoxyuridine triphosphate nick end labeling (TUNEL).lmmunohistochemistry and western-blot anylysis of NF-?B protein expression.Results NF-?B was obviously expression on injury myocardium of IR group,and increased significantly in contrast to control group (P0.05)Conclusions NF-?B might play an important role in acute myocardial ischemia reperfusion.PDTC reduces myocardial iscbemia/repeffasion injury by preventing expression of factor NF-?B.

The vip3A gene of Bt9816C was cloned and the sequencing result was submitted to GenBank (accession no.AY945939). The gene was identified as a novel vip3Aa gene, which was assigned name vip3Aa18 by the Bacillus thuringiensis delta-endotoxin nomenclature committee. Subsequently, vip3Aa18 was expressed in Escherichia coli BL21 and bioassay demonstrated that the purified recombinant Vip3Aa18 had high toxicity against Helicoverpa armigera and Spodoptera exigua. The results of sequence analysis revealed that a carbohydrate binding domain exists on the C-termini 536 to 667 residues of Vip3Aa18,which maybe participate in binding to midgut receptors in susceptible insects. Moreover, a transmembrane helices located on N-termini 272 to 292 residues was proposed responding for pore formation. Furthermore, a putative disulfide bond was found in the Vip3Aa18 sequence. The specific structures and sites of Vip3Aa18 sequence imply potential function.

Objective To investigate the clinical characteristics of infectious diseases of CNS.Methods Inpatients treated in the second hospital of Hebei Medical University from 1996 to 2005 were subjected to retrospective study.Results During 10 years,the hospitalization number of infectious diseases of CNS was 3929.The proportion of inpatients with viral meningitis(encephalitis),cerebral cysticercosis,tuberculous meningitis(TBM),purulent meningitis(PM)and cryptococcal meningitis(CM) was 63.8%,17.4%,7.7%,0.7% respectively.The hospitalization number of viral meningitis (encephalitis),TBM,PM and CM in the 2001—2005 5-year period was 53.5%,21.3%,35.3%,and 77.3% higher than that of the 1996—2000 period.Whereas the hospitalization number of cerebral cysticercosis decreased by 32.4% than that of the last 5 years.The peak months of viral meningitis (encephalitis)in a year were July,August and September.The peak months of TBM in a year were April, May and June.The case fatality of viral meningitis(encephalitis),cerebral cysticercosis,TBM,PM and CM was 8.1%,6.9%,22.4%,12.9%,33.3% respectively.Conclusions In the past l0 years,the incidence of common infectious diseases of CNS has increased in Shijiazhuang except cerebral cysticercoids. Our vigilance should be improved and some effective measures should be adopted to keep away infectious diseases of CNS.
