Objective To detect whether and where brain functional connectivity exists in the resting state of patients with early-onset schizophrenia by using functional magnetic resonance imaging (fMRI). Methods Nineteen early-onset schizophrenic patients were diagnosed with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) of American Psychiatric Association. The 19 early-onset schizophrenic patients and another 19 healthy volunteers underwent fMRI in resting state. Cingulate gyrus was selected as region of interest and the difference was analyzed in the cingulate gyrus functional connectivity pattern between the 19 patients with early-onset schizophrenia (EOS) and 19 matched controls using resting-state fMRI. A two-sample t test was performed on the individual in a voxel by voxel manner. Results Statistical map was set a combined threshold of P＜0.005 and the number of voxel>20. Functional connectivity in the resting state was abnormal in the patients,including decreased functional connectivity and increased functional connectivity. The abnormal area was distributed all over the brain. The brain area with decreased functional connectivity included bilateral posterior cerebellar lobes, superior frontal gyrus, middle frontal gyrus, gyrus rectus,hippocampus, cuneus gyrus,fusiform gyrus,middle occipital gyrus,inferior occipital gyrus, right inferior temporal gyrus,right middle temporal gyrus, and right angular gyrus. The brain area with increased functional connectivity included left middle temporal and left inferior temporal gyrus. Conclusion Abnormal cingulate gyrus functional connectivity of schizophrenia might exist in the resting state. Resting state fMRI is important for the research of schizophrenia.

AIM: Research report that bone marrow stem cells mobilized by recombinan human granulocyte colony-stimulating factor (rhG-CSF) can migrate to lesion spot of infarction, thus decrease brain edema and brain injury after cerebral ischemia. But the report about the effect of drug on brain edema after cerebral hemorrhage is rare. This study investigated the effects of bone mar- row stem cells mobilized by rhG-CSF on reducing formation of brain edema and downregulation of matrix metalloproteinase (MMP)-9 in the peripheral area after intracerebral hemorrhage (ICH) in rats. METHODS:The experiments were performed at the Central Laboratory of Luzhou Medical College from March to November in 2006. ① 144 healthy male SD rats, (300?20)g, were provided by Animal Department of Luzhou Medical College. The experimental procedures of disposing animals were accorded with ethical standards. ②Experimental rats were assigned randomly into a sham operation group, a ICH group and a treatment group, equally. According to the method of Yang, rat models of ICH were made by the method cutting off tail of rat to obtain autoblood in the ICH and treatment groups. Rats in the sham operation group received saline instead of autoblood. Rats in the treatment group were administered with rhG-CSF (60 ?g/kg) by intrap- eritoneal injection after 1 hour. ③The water contents and MMP-9 were measured in each group by immunohistochemical method. RESULTS:Of 144 rats, 16 rats dropped out, among which 7 rats were estimated as 0 grade and 9 rats died, and all were supple- mented. ①The water contents were higher in the ICH group than in the sham operation group (P

BACKGROUND: Recombinant human granulocyte colony-stimulating factor (rhG-CSF) can mobilize endothelial progenitor cells and enhance new vessels at cerebral ischemia region. OBJECTIVE: To investigate the effects of rhG-CSF on the new microvascular expressions in rat perihematoma after intracerebral hemorrhage. DESIGN, TIME AND SETTING: A randomized control animal experiment was performed at the Central Laboratory of Luzhou Medical College from March to November 2006. MATERIALS: A total of 72 healthy male Sprague Dawley rats and rhG-CSF were used for this study. METHODS: Seventy-two rats were equally and randomly assigned into the sham operation group, the hemorrhage group, the treatment group. According to rat brain stereotaxic atlas, models of intracerebral hemorrhage were made by infusing autoblood from rat tails. Rats in the sham operation group were infused with saline instead of autoblood. Rats in the treatment group were administered rhG-CSF (60 ?g/kg) by intraperitoneal injection at 1 hour after operation. Rats in the sham operation and hemorrhage groups were left intact. MAIN OUTCOME MEASURES: The microvascular expressions of CD34+ in perihematoma were detected at 6, 12, 24, 48 and 72 hours, 7 days; Four rats in each time point. Microvascular production was measured by changes in CD34. The more the CD34 antigens, the more the new vessels were. RESULTS: In the hemorrhage group, the microvascular expressions of CD34+ were significantly higher compared to the sham operation group (P 0.05). Significant differences were measured at 6, 12, 24 and 48 hours (P

OBJECTIVE: To evaluate the inhibiting effects of the root of Mallotus apelta (Lour.) Muell.-Arg. on duck hepatitis B virus (D-HBV) in vivo. METHODS: Forty nestling ducks with congenitally infection of D-HBV detected by PCR were randomly divided into five groups: untreated group, lamivudine-treated group, and high-, medium- and low-dose root of Mallotus apelta-treated groups. The ducks in the lamivudine-treated group were fed lamivudine with a dose of 50 mg/kg once. Ducks in the three-dose Mallotus apelta-treated groups were treated with different doses of decoction of this herbal medicine for 21 days respectively. The serum content of D-HBV DNA was determined by quantitative real-time PCR technique before and 7 days after the treatment, and on the 7th, 14th and 21st day of the treatment. Liver biopsy was also executed before and after the treatment to observe the histopathological changes. RESULTS: Lamivudine showed a rapid inhibiting effect on D-HBV DNA, but this effect didn't last long, and the serum level of D-HBV DNA increased again after treatment. The serum level of D-HBV DNA dropped markedly in the high- and medium-dose Mallotus apelta-treated groups on the 14th and 21st day. Low-dose Mallotus apelta revealed no obvious inhibiting effect on D-HBV. After treatment, the inhibiting effect in the root of Mallotus apelta-treated group continued as compared with that in the untreated group. The histopathological changes of liver tissues showed that the inflammation in the high-dose root of Mallotus apelta-treated group was weakened as compared with that in the lamivudine-treated group. CONCLUSION: The root of Mallotus apelta has therapeutic effect on D-HBV. It can restrain the duplication of D-HBV in vivo. Although this effect is weaker than that of lamivudine, it continues longer. Thus this herbal medicine is an effective, safe and economical drug for hepatitis B.

Objective To investigate the incidence of sub-health fatigue among medical workers exposing to radioactive rays, and to observe the therapeutic effect of Bushen Jianpi recipe on sub-health fatigue. Methods An investigation was carried out among 1 056 medical workers exposing to radioactive rays which were from the medical and sanitary institutions of Guangzhou city. Sixty cases subjecting to the inclusion criteria were sampled from the investigated population by epidemiological methods for the randomized controlled trial. The subjects were evenly randomized into treatment group and control group. Both groups received health education and health-promoting lifestyle, and the treatment group was given self-prescribed Bushen Jianpi recipe additionally. The treatment lasted for 4 weeks. The scores of Multidimensional Fatigue Inventory ( MFI-20) and Sub-health Measurement Scale Version 1.0 ( SHMS V1.0) were observed before and after treatment, and the therapeutic effect was evaluated after treatment. Results ( 1) We got 976 effective questionnaires, and the effective response rate was 92.4%. Among the admitted 976 workers, the incidence of sub-health state was 66.8% (652/976) and that of sub-health fatigue is 31.4% ( 205/976). ( 2) The total effective rate was 80.0% in the treatment group and was 36.7% in the control group, the difference being significant ( P<0.01). ( 3) After treatment, the scores of MFI-20 and SHMS V1.0 were decreased in the treatmeat group, and fatigue symptom scores were decreased in the control group ( P<0.05 or P<0.01) , the decrease in the treatment group being superior to that in the control group ( P<0.05 or P<0.01). Conclusion The incidence of sub-health fatigue is popular in the medical workers exposing to radioactive rays, and Bushen Jianpi recipe has an effect on improving the sub-health fatigue.

Objective: To explore the relationship between isochronous substitution and BMI, waist circumference (WC), and body fat rate (FAT) among physical activity (PA), sedentary (SB), and sleep (SLP), so as to provide effective measures for obesity control in adolescents. Methods: A total of 193 adolescents aged 12-15 (90 males and 103 females) was randomly selected, and their height, weight, and BMI were measured using routine testing methods from May to August 2022. The PA, SB and SLP of the participants were measured using a 3D accelerometer (ActiGraph GT3X+). Results: The arithmetic mean value overestimated SLP (40.8%) and SB (39.6%) to some extent, and underestimated LPA (16.1%) and MVPA (3.5%) to some extent. Based on the ISM at 15 min, MVPA was substituted for other activity, BMI Z decreased by 0.17-0.22 units, WC Z decreased by 0.16-0.20 units, and FAT Z decreased by 0.17-0.22 units. The substitution between MVPA and for other activity exhibited significant asymmetry. The effects of MVPA substitutions for SB was the largest, followed by the effects of MVPA substitutions for SLP, and the effects of MVPA substitutions for LPA was the lowest. As MVPA substitutions for other behaviors, it reached its maximum (0.06-0.08 units ) when the MVPA time increased by 5 minutes. Conclusions MVPA plays an irreplaceable role in the control of adolescent obesity . While reducing SB time, MVPA duration should be increased to ensure that the daily MVPA duration is not less than 55 minutes in order to effectively control obesity.
