OBJECTIVE: To study the correlation of daily living activities with location and severity of trau- matic brain injury (TBI) and to provide a theoretical basis for improving the accuracy of expert opinion. METHODS: Five hundred and one cases of patients with TBI were selected. Detailed records included following: pre-injury situation, location and severity of injury, treatment and education. Daily living activi- ties scale (Barthel index) was applied to test the subjects' daily living activities. The relevance among location and severity of TBI and Barthel index was statistically analyzed. RESULTS: In mild TBI group, there was no significant difference in Barthel index among each location (P>0.05). In moderate TBI group, there were significant differences in Barthel index between subarachnoid hemorrhage and cerebral lobe injury, also between parietal, occipital lobes injury and frontal lobe injury, parietal, occipital lobes injury and temporal lobe (P<0.05), respectively, whereas no significant difference in Barthel index between frontal lobe injury and temporal lobe injury (P>0.05). In severe TBI, there were significant differences in Barthel index between every two different locations (P<0.05). CONCLUSION There is some correlation between the location of TBI and Barthel index, which provides an important reference value for analyzing and determining daily living activities after TBI.

Objective:To observe the effect of acupuncture in regulating ubiquitin-proteasome pathway (UPP),and discuss the action of acupuncture in intervening heroin-induced brain damage.Methods:Thirty male Sprague-Dawley (SD) rats were divided into a control group,a model group and an acupuncture group by using the random number table.Rats in the model and acupuncture groups received intramuscular heroin injection for successive 8 d at a progressively increased dose.Afterwards,the injection was suspended for 5 d for withdrawal.The heroin relapse rat model was established by repeating the drug addiction and withdrawal process for 3 times.The control group followed the step of the model establishment,but was given intramuscular injection of normal saline at the stage of addiction and no intervention at the stage of withdrawal;the model group was given intramuscular heroin injection at a progressively increased dose at the addiction stage and no intervention at the withdrawal stage;the acupuncture group was dealt in the same way as the model group at the addiction stage,but received acupuncture at Baihui (GV 20) and Dazhui (GV 14) at the withdrawal stage,with the needles retained for 30 min each time,1 session a day,for successive 5 d.On the 39th day,brain tissues were extracted from the hippocampus and ventral tegmental area (VTA) of the three groups of rats.The apoptosis of brain nerve cells was detected by using terminal deoxynucleotidyl transferase-mediated nick and labeling (TUNEL).The mRNA and protein expressions of ubiquitin (Ub),ubiquitin protein ligase (E3) and 26S were examined by immunohistochemistry and quantitative real-time polymerase chain reaction (RT-qPCR).Results:Compared with the model group,rat's hippocampus and VTA in the acupuncture group showed significantly fewer cells positively stained by TUNEL staining (P＜0.01),and its mRNA and protein expressions of Ub,E3,26S were significantly lower (P＜0.01).Conclusion:Reducing nerve cell apoptosis and regulating the mRNA and protein expressions of Ub,E3 and 26S in rat's hippocampus and VTA are possibly one of the action mechanisms of acupuncture in intervening heroin-induced brain damage.

The effect of acupuncture on substance withdrawl syndromes and craving relapse prevention of the recent 10 years were reviewed as well as its mechanism. The therapeutic effect and the possible mechanism were analyzed on the basis. From the three aspects of anti protracted abstinence symptoms, craving relapse prevention and mechanism of acupuncture, the development tendency and the prospect of application on drug withdrawl with acupuncture were expected. And it is proposed that clinical observation of acupuncture intervention on craving should be developed, the mechanism of acupuncture impact on cognitive behavior, blocking study and memory processing related to drug addiction should be explored, so as to further give play to the advantages of acupuncture on anti-drug addiction.

OBJECTIVESTo study the occurrence of different anomalies associated with hypospadias and to instruct relevant treatment in clinical practice.

METHODSThree hundred and forty-one cases of hypospadias were investigated, all treated respectively corresponding to their specific anomalies.

RESULTSThe morbidity of associated anomalies in cases of hypospadias was as high as 21.1%. Most of the anomaly cases were undescended testes and inguinal hernia, and the incidence of associated anomalies was related to the degree of hypospadias.

CONCLUSIONSHypospadias is not just a local dysmorphic problem but rather a local manifestation of a systemic disease. It is necessary to take those associated anomalies as a systemic whole and attach enough importance to their clinical treatment.

BACKGROUNDAmyloid β(1-42) (Aβ(42)) peptide vaccination has been proved to be effective in reducing amyloid burden in brain and improving cognitive function in Alzheimer's disease (AD) mouse models. But the phase II trial of Aβ(42) peptide vaccine was halted because of T cell-mediated meningoencephalitis. In this study, a DNA vaccine, p(Aβ(3-10))(10)-CpG, was constructed to test whether it would induce predominant T(H)2 immune response upon immunization of BALB/c mice.

METHODSBALB/c mice were vaccinated intramuscularly with p(Aβ(3-10))(10)-CpG plasmids. Aβ(42) peptide, pcDNA3.1(+) empty vector and PBS were injected to the control groups. Expression of interesting gene in injected muscle was identified by immunohistochemistry. Anti-Aβ antibody titers, isotype profiles as well as cytokines in ex vivo splenocytes culture supernatants were analyzed by enzyme-linked immunosorbent assay (ELISA).

RESULTSP(Aβ(3-10))(10)-CpG plasmid was expressed in muscle after injection detected by immunohistochemistry. The p(Aβ(3-10))(10)-CpG vaccine induced high titers of anti-Aβ antibodies in BALB/c mice. And isotype of the antibodies was mainly IgG1, the IgG1/IgG2a ratio for the p(Aβ(3-10))(10)-CpG group was approximately 5 times greater than that for the Aβ(42) peptide group. Ex vivo cultured splenocytes isolated from mice immunized with p(Aβ(3-10))(10)-CpG exhibited high interleukin-4 response and low interleukin-γ (IFN-γ) response.

CONCLUSIONSImmunization with p(Aβ(3-10))(10)-CpG vaccine primarily induces a T(H)2 type of response, thus reduces the probability of inflammation. This p(Aβ(3-10))(10)-CpG vaccine possesses the basic factors required for a safe and effective AD vaccine.

BACKGROUNDCT perfusion imaging (CTP) has been proved to be a powerful functional imaging technique. This study aimed to evaluate the value of CTP in guiding biopsy of pulmonary lumps.

METHODSA total of 147 patients with pulmonary lumps who had CT guided biopsies were enrolled in this study from February 2005 to June 2007. The patients were assigned to 3 groups: 33 cases guided by CTP as group I, 45 cases guided by contrast-enhanced scan of CT as group II, and 69 cases guided by plain scan of CT as group III. Each group was subdivided into central and peripheral types according to the location of the lumps. The achievement ratio of biopsy, the accuracy in grouping, and grading of lung cancer, and the incidence of complication were compared.

RESULTSThe total achievement ratios of biopsy from group I to III were 100% (33/33), 91% (41/45), and 80% (55/69) respectively, and the difference was statistically significant between group I and III (P < 0.05). For the central type, they were 100% (18/18), 88% (15/17), and 79% (11/14) respectively, and the difference was also statistically significant between group I and III (P < 0.05). For the peripheral type, they were 100% (15/15), 93% (26/28), and 80% (44/55) respectivelies, and the difference was not statistically significant among the three groups. The total accuracies in grouping and grading of lung cancer from group I to III were 100% (27/27), 91% (31/34), and 72% (33/46) respectively, and the difference was statistically significant between group I and III and between group II and III (P < 0.05). For the central type, they were 100% (16/16), 94% (16/17), and 70% (8/12) respectively, and the difference was statistically significant between group I and III (P < 0.05). For the peripheral type, they were 100% (11/11), 88% (15/17), and 72% (26/36) respectively, and the difference was statistically significant between group I and III (P < 0.05). The total incidence of complication from group I to III were 15% (5/33), 27% (12/45), and 43% (30/69) respectively, and the difference was statistically significant between group I and III (P < 0.01). For the central type, they were 11% (2/18), 24% (4/17), and 57% (8/14) respectively, and the difference was statistically significant between group I and III (P < 0.01). For the peripheral type, they were 20% (3/15), 29% (8/28), and 40% (22/55) respectively, and no statistically significant difference was found among the three groups.

CONCLUSIONSCTP guided biopsy of pulmonary lumps using multi-detector row CT has the potential to improve the accuracy of histopathological diagnosis with a lower risk and higher achievement ratio. More research and technical improvements are needed before it is widely used.

This study was aimed to investigate clinical and prognostic significances of 4 target antigens (CD19, CD20, CD22 and CD33) for antibody-based immunotherapy and to evaluate the applications of these antibody-based target therapy to adult acute lymphoblastic leukemia (ALL). The immunophenotype of 220 adult patients with ALL were analyzed by four-color flow Cytometry, and cytogenetic and molecular parameters were detected by conventional cytogenetics, fluorescence in situ hybridization, real-time quantitative PCR, nested PCR and DNA sequencing. The results showed that CD19 positive (CD19(+)) cases were more in female (46.4% vs. 23.4%, P = 0.006), elderly patients aged > 60 years (14.4% vs. 2.1%, P = 0.022), CD33(+) co-expression cases (47.8% vs. 12.0%, P = 0.001) and genetic high-risk group (55.8% vs. 20.8%, P = 0.002) compared with CD19 negative (CD19(-)) cases; CD20(+) cases had lower co-expression of CD13 than CD20(-) cases (31.6% vs.67.1%, P = 0.000) and no significant prognostic indications for CD20(+) was observed; CD22(+) cases had higher relapse rate at 12-month than CD22(-) cases (93.9% vs.57.1%, P = 0.041) in B-ALL patients; CD33(+) cases had higher incidence of Ph(+) than CD33(-) cases (43.5% vs.19.4%, P = 0.007) and significantly correlated with Ph(+) (r = 0.261, P = 0.006). It is concluded that elucidation of the characteristics of the target antigens (CD19, CD20, CD22, CD33) used for antibody-based immunotherapy will help hematologists making the correct decision whether and when to use these antibody-based target therapies.
