Objective: To observe the effect of electroacupuncture (EA) on serum interleukin (IL)-6, IL-8 and IL-10 in rat models of cerebral ischemia-reperfusion, and to discover the mechanism of EA in preventing and treating cerebral ischemia.
Methods:Male Sprague Dawley (SD) rats were randomized into a sham-operation (SO) group, a model control (MC) group, and an EA group, which were sub-grouped into a 6-hour group and a 24-hour group. In the SO group, rats only received vessel separation with filament placed inside without any treatment. In the MC and EA groups, the focal cerebral ischemia-reperfusion model was induced by using modified Longa method with intraluminal filament. The MC group didn’t receive any treatment;the EA group received EA at Baihui (GV 20) and Dazhui (GV 14) with sparse-dense wave for 30 min. The levels of serum IL-6, IL-8 and IL-10 were detected by using Elisa test.
Results: Six hours after ischemia-reperfusion injury, the levels of serum IL-6, IL-8 and IL-10 in the MC group were significantly higher than those in the SO group (P<0.01, P<0.05, P<0.05);the level of serum IL-8 in the EA group was significantly lower than that in the MC group (P<0.05), while there were no significant differences in comparing IL-6 and IL-10 between the EA group and the MC group. Twenty-four hours after ischemia-reperfusion injury, the levels of serum IL-6 and IL-8 in the EA group were significantly lower than those in the MC group (both P<0.05), while there were no significant differences in comparing the level of IL-10 among the three groups.
Conclusion:Early intervention by EA can regulate the levels of serum IL-6 and IL-8 in cerebral ischemic injury.

OBJECTIVETo compare therapeutic effects between clavicular hook plate and tension band fixation for the treatment of Allman type II to III sternoclavicular joint dislocations.

METHODSA retrospective survey was analyzed from May 2000 to September 2008. A total of 31 patients with Allman type II to III sternoclavicular joint dislocations were followed up. Sixteen patients were fixed with the clavicular hook plate (Group A) including 11 males and 5 females, with a mean age of (37.4 +/- 7.3) years. Fifteen patients were treated with tension band fixation (Group B) including 9 males and 6 females, with a mean age of (35.6 +/- 5.1) years. The indexes of intra-operation and during the hospital stay, the clinical outcomes and postoperative complications were statistically compared.

RESULTSAll the patients were followed up for 12 to 37 months, with an average of 20 months. There was no significant differences in data of operative time, blood loss and length of incision between the two group (P > 0.05); however, the economic cost was significantly much more in Group A (P < 0.01). Also, there was statistically difference in the incidence of complications between the two groups (P = 0.023), which were 2 patients in Group A and 8 patients in Group B. According to Rockwood evaluation criteria, in group A, 13 patients got an excellent result, 2 good and 1 poor; in group B, 10 patients got an excellent result, 3 good, 1 poor and 1 bad. There were no statistical difference in good and excellent rate.

CONCLUSIONThe clavicular hook plate for the treatment of Allman type II to III sternoclavicular joint dislocation is believed to be as good as tension band fixation, but there are fewer complications and in favor of early exercise.

The present study investigated the relationship between DNA-dependent protein kinase (DNA-PK) and radiosensitivity of nasopharyngeal carcinoma (NPC) cell lines. The dose-survival relationship for NPC cell lines, CNE1 and CNE2, was analyzed using clonogenic formation assay, the activity of DNA-PK of the two cell lines was measured using the Signa TECT DNA-PK assay kit, and the localization and expression of Kus (a heterodimer) and DNA-PKcs protein in CNE1 and CNE2 before irradiation and 15 min, 1 h, 6 h, 12 h, 24 h after 4 Gy irradiation were analyzed by immunofluorescence, laser scanning confocal microscope (LSCM) and Western blot. The results showed that the surviving fraction of CNE1 was higher than that of CNE2 at each dose. The DNA-PK activity of CNE1 was also significantly higher than that of CNE2 before and after irradiation (P<0.05), while the expression of total Ku70/Ku80 in CNE1 and CNE2 had no significant difference. Increasing translocation of Ku70 and Ku80 from the cytoplasm to the nuclei in the two cell lines was observed with increase of irradiation time as detected by Western blot, and the immunofluorescence of the DNA-PK complex subunits showed greater nuclear translocation in CNE1 than CNE2 after irradiation. The results suggest that the relatively higher radio-resistance of CNE1 correlates with the higher activity of DNA-PK as compared to that of more radiosensitive CNE2 (or lower radio-resistance) before and after irradiation. Thus, DNA-PK activity may be a useful predictor of radiosensitivity of NPC.

OBJECTIVETo evaluate the correlation between standardized uptake valus (SUV) of 18F-fluorodeoxyglucose (18 F-FDG) of tumor at PET/CT examination and the expression of glucose transporter-1 (Glutl) and Ki-67 in esophageal cancer.

METHODS56 patients with esophageal cancer were evaluated with 18 F-FDG PET/CT examination before operation. The expression of Glut1 and Ki-67 antigen in the tumor tissues was detected by immunohistochemistry after operation.

RESULTS(1) Positive rate of Glutl and Ki-67 expression in esophageal cancer tissues was 100% , respectively. There was a positive correlation between the expression of Glutl and Ki-67 and the clinical stages and differentiation of the tumor. The more the tumor and the clinical stages were advanced and the lower was the tumor differentiation, the more Glutl and Ki-67 were expressed. (2) There were abnormal radioactive high uptake regions on PET/CT imaging of esophagus in the 56 patients, which were confirmed by pathology as the primary carcinoma. The SUV was higher than 2. 5. There was a gradually increasing tendency in SUV along with the lowering of the tumor differentiation and the advance of clinical stages. (3)There was a correlation between the expression of Glutl, Ki-67 and the SUV, the more Glutl and Ki-67 were expressed, the higher the SUV of tumor 18F-FDG at PET/CT examination was in esophageal tumor tissues.

CONCLUSIONThere is a widespread expression of Glutl in esophageal cancer tissues, and the SUV may be used to indirectly evaluate the proliferative capacity of esophageal cancer.

OBJECTIVETo investigate the phenotype, frequency and function of CD4+ T cell subsets and the relevant cytokines, as well as the relationship between these cells and appearance of pneumonia of novel (H1N1) influenza A patients.

METHODS68 healthy people, 53 confirmed novel A(H1N1) influenza patients without pneumonia and 16 confirmed severe novel A (H1N1) influenza patients with pneumonia were enrolled in this study. Viral load in nasopharyngeal swabs specimens was measured by real time PCR assay. The phenotype and percentage of CD4+ T cell subsets including Th1, Th2, Th17, and Treg cells were measured by Flow cytometry analysis. The relevant cytokines in plasma including TGF-beta, IL-6 and IFN-gamma were measured by ELISA. Data was analyzed by one way ANOVA.

RESULTSIt was found that peak viral load and viral shedding period of severe patients with pneumonia was significantly increased compared with mild patients without pneumonia (P < 0.05). The percentage of Th17 cells of severe patients with pneumonia was significantly diminished compared to that of healthy subjects and mild patients without pneumonia (P < 0.05). However, Th1, Th2, Treg cells frequencies had no significant differences (P > 0.05) among these three groups. The level of TGF-beta in plasma for the severe patients with pneumonia was also significantly decreased compared to that of healthy subject and mild patients without pneumonia (P < 0.05). The viral shedding period inversely correlated with the frequency of Th17 cells (r = - 0.38, P < 0.05).

CONCLUSIONH1N1 influenza A virus can inhibit Th17 cells to differentiate, particularly more extent in patients with pneumonia. Impaired Th17 cells may correlate with viral clearance and pneumonia of novel H1N1 influenza A patients.

OBJECTIVETo investigate the relationship of susceptibility loci in chromosomes 1q21-25 and 6p21-25 and schizophrenia subtypes in Chinese population.

METHODSA genomic scan and parametric and non-parametric analyses were performed on 242 individuals from 36 schizophrenia pedigrees, including 19 paranoid schizophrenia and 17 undifferentiated schizophrenia pedigrees, from Henan province of China using 5 microsatellite markers in the chromosome region 1q21-25 and 8 microsatellite markers in the chromosome region 6p21-25, which were the candidates of previous studies. All affected subjects were diagnosed and typed according to the criteria of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revised (DSM-IV-TR; American Psychiatric Association, 2000). All subjects signed informed consent.

RESULTSIn chromosome 1, parametric analysis under the dominant inheritance mode of all 36 pedigrees showed that the maximum multi-point heterogeneity Log of odds score method (HLOD) score was 1.33 (α = 0.38). The non-parametric analysis and the single point and multi-point nonparametric linkage (NPL) scores suggested linkage at D1S484, D1S2878, and D1S196. In the 19 paranoid schizophrenias pedigrees, linkage was not observed for any of the 5 markers. In the 17 undifferentiated schizophrenia pedigrees, the multi-point NPL score was 1.60 (P= 0.0367) at D1S484. The single point NPL score was 1.95(P= 0.0145) and the multi-point NPL score was 2.39 (P= 0.0041) at D1S2878. Additionally, the multi-point NPL score was 1.74 (P= 0.0255) at D1S196. These same three loci showed suggestive linkage during the integrative analysis of all 36 pedigrees. In chromosome 6, parametric linkage analysis under the dominant and recessive inheritance and the non-parametric linkage analysis of all 36 pedigrees and the 17 undifferentiated schizophrenia pedigrees, linkage was not observed for any of the 8 markers. In the 19 paranoid schizophrenias pedigrees, parametric analysis showed that under recessive inheritance mode the maximum single-point HLOD score was 1.26 (α = 0.40) and the multi-point HLOD was 1.12 (α = 0.38) at D6S289 in the chromosome 6p23. In nonparametric analysis, the single-point NPL score was 1.52 (P= 0.0402) and the multi-point NPL score was 1.92 (P= 0.0206) at D6S289.

CONCLUSIONSusceptibility genes correlated with undifferentiated schizophrenia pedigrees from D1S484, D1S2878, D1S196 loci, and those correlated with paranoid schizophrenia pedigrees from D6S289 locus are likely present in chromosome regions 1q23.3 and 1q24.2, and chromosome region 6p23, respectively.
