Objective To research the applications of resting-state functional MRI in conjunction with voxel-based morphometry on cerebral functions and structures in patients with schizophrenia. Methods Thirty-two patients with schizophrenia and 32 healthy people underwent resting state functional magnetic resonance imaging (Rs-fMRI)and sagittal scanning T1WI with 3D FFE Pulse Sequence. Rest1.8 software was applied to calculate the differences of amplitude of standardized low-frequency fluctuation(ALFF)between the two groups,then the voxel-based morphometry(VBM)data of abnormal brain regions were evaluated to compare the differences of grey matter intensity. Finally,combining with ALEF and VBM,we explored the changes of cerebral functions and structures. Results As compared to the control group ,the ALFF-elevated regions were the right putamen ,the left orbital frontal cortex extending to the left putamen and left dorsal-lateral superior frontal gyrus;the ALFF-decreased regions were the right inferior tempotalgyrus,the left posterior cingulated gyrus and the left angular gyrus(P<0.05). No elevated regions of grey matter intensity were found in the patient group. Conclusions Extensive abnormal active regions of the brain under resting state could be found in patients with schizophrenia ,the grey matter intensity of abnormal regions also decreased generally. They are in accordance with the glutamate-hypothesis of schizophrenia ,which involves extensive impairments of neurons ,disorders of neurotransmitter′s circulations and balances.

Objective To explore the necessity of opening nephrostomy tube for patients with septic shock follow-ing the indwelling double-J stent of post-percutaneous nephrolithotomy (PCNL),and provide reference for the treatment of septic shock after PCNL.Methods 60 patients with septic shock after PCNL in a hospital from January 1,2015 to December 30,2016 were chosen,patients were randomly divided into clipping nephrostomy tube group (clipping group,n =30) and opening nephrostomy tube group (opening group,n =30),clinical data of two groups of patients were collected and analyzed.Results After 24-hour treatment,heart rate (HR),mean arterial pressure (MAP),oxygen saturation (SpO2),serum lactate (Lac),and hourly urine volume all improved in both groups of patient compared with pre-treatment(all P＜0.05);HR,MAP,SpO2,Lac,and hourly urine volume in opening group after 24-hour treatment were all significantly different from clipping group (all P＜0.05).Levels of serum procalcitonin (PCT) and C-reactive protein (CRP) in two groups after 3-day treatment decreased significantly compared with pre-treatment (both P＜0.05);PCT and CRP levels in opening group after 3-day treatment were both significantly lower than clipping group (both P＜0.05);cure rate of two groups were both 100.00％,hospitalization time and extubation time in opening group were both shorter than clipping group,and cost was less than clipping group,difference were all significant(all P＜0.05).Conclusion Opening nephrostomy tube on the basis of indwelling double-J stent is necessary for patients with septic shock after PCNL.

The dosage-efficacy/toxicity relationship of the 50% alcohol extracts of Polygonum multiflorum was comparatively investigated on either normal or CCl4-induced chronic liver injury rats, by determining the general condition, serum biochemical indices and liver histopathology, coupled with the factor analysis. The dosages were 10 and 20 g raw materials per kg body weight. Compared with the normal control group, the normal high dose group showed significant increases of the serum alanine transaminase (ALT), total bilirubin (TBIL), high mobility group box 1 (HMGB-1) and interleukin-1β (IL-1β) (P < 0.05 or P < 0.01), as well the frequent incidences of inflammatory cell infiltration, hepatic sinus enlargement and fiber stripes formation in histopathological sections. Compared with the model control group, the model low dose group showed significant declines of serum ALT, aspartate transaminase (AST) and total bile acid (TBA) (P < 0.05), as well the alleviation of vacuoles of hepatocytes, but no amelioration of the inflammatory cell infiltration and fibrous tissue hyperplasia; moreover, the model high dose group showed significant degeneration declines of serum HMGB-1, tumor necrosis factor-α (TNF-α) and IL-1β (P < 0.05, P < 0.01), as well the evident alleviation of vacuoles degeneration of hepatocytes, inflammatory cells infiltration and fibrosis degree. The factor analysis showed that the low dosage treatment had almost neither injuring effect on the normal rats nor protective effect on the model rats; while the high dosage treatment showed observable injuring effect on the normal rats, expressed by the significant increases of the factor-1 (HMGB-1, TNF-α and IL-1β as the main contributors) and factor-2 (TBIL, ALT and TBA as the main contributors) relative to the normal control group. The liver protective effect of the high dosage treatment could be observed with the significant reduction of the factor-1, indicating the effective alleviation of the expression of inflammatory cytokines. In conclusion, it could illustrated the phenomenon of symptom-based prescription theory of Polygonum multiflorum on rat livers: the high dosage of the herb had either an injuring effect on normal rats, or a therapeutic effect on the rats with chronic liver injury.

BACKGROUNDIrradiation dose and volume are the major physical factors of radiation-induced lung injury. The study investigated the relationships between the irradiation dose and volume in radiation-induced lung injury by setting up a model of graded volume irradiation of the rat lung.

METHODSAnimals were randomly assigned to three groups. The ELEKTA precise 2.03 treatment plan system was applied to calculate the irradiation dose and volume. The treatment plan for the three groups was: group 1 received a "high dose to a small volume" (25% volume group) with the mean irradiation volume being 1.748 cm(3) (25% lung volume); the total dose and mean lung dose (MLD) were 4610 cGy and 2006 cGy, respectively (bilateral AP-PA fields, source to axis distance (SAD) = 100 cm, 6MVX, single irradiation); Group 2 received a "low dose to a large volume" (100% volume group) with the mean irradiation volume being 6.99 cm(3) (100% lung volume); the total dose was 1153 cGy. MLD was 2006 cGy, which was the same as that of group 1 (bilateral AP-PA fields, SAD = 100 cm, 6MVX, single irradiation); Group 3 was a control group. With the exception of receiving no irradiation, group 3 had rest steps that were the same as those of the experimental groups. After irradiation, functional, histopathological, and CT changes were compared every two weeks till the 16th week.

RESULTSFunctionally, after irradiation breath rate (BR) increases were observed in both group 1 and group 2, especially during the period of 6th - 8th weeks. The changes of BR in the 100% volume group were earlier and faster. For the 25% volume group, although pathology was more severe, hardly any obvious increase in BR was observed. Radiographic changes were observed during the early period (the 4th week) and the most obvious changes manifested during the mediated period (the 8th week). The extensiveness of high density and the decreased lung permeability were presented in the 100% volume group, and ground glass opacity and patchy consolidation were presented in the 25% volume group without pleural effusion, pleural thickening, and lung shrinking. Morphologically, the 100% volume group mainly presented signs of vascular damage, including signs of vascular wall edemas, hypertrophy, and sclerosis. The 25% volume group mainly presented with erythrocyte cell exudation, inflammation, and parenchymal damage.

CONCLUSIONSThe delivery of a small dose of radiation to a large volume is not safe. A low dose smeared out over large volumes, albeit reversible, may lead to fatal respiratory dysfunction. Damage to the lung may be more dependent on the volume of irradiation than on the radiation dose. Clinically, the safest approach is to limit both the volume of the irradiated normal lung and the amount of received radiation.

Objective To learn the current status of health literacy of residents in Wenling City, and to explore the relationship between health literacy and socioeconomic status. Methods A total of 3200 residents aged 15-69 years old from 6 townships were selected by stratified multi-stage random sampling method and probability proportionate to size sampling (PPS) method, and a questionnaire surveyed was conducted. Results Totally 3189 questionnaires were effective and the overall level of health literacy of residents was 19.79％ (631/3189) . The percentages of residents who had the basic health knowledge and concept, healthy lifestyle and behavior, health related skills were 23.27％、 24.21％ and 23.83％, respectively. About 55.47％ of residents had the literacy of safety and first-aid, which was the highest, followed by 38.66％ with scientific health belief, 32.77％ with literacy for disease prevention, 26.12％ with health information, 14.14％ with primary medical care and 7.49％ with the literacy for chronic disease prevention. Logistic regression model showed that the health literacy level with institutions class was 2.25 times of manual workers class, and the health literacy level of people have bachelor degree or above was 6.93 times less literate or illiterate, and the health literacy level of family income of 200 thousand Yuan and above was 7.70 times of 0～50 thousand Yuan. The health literacy were different among different socioeconomic status residents (P<0.01) . Conclusion There are obvious gaps in health literacy among different socioeconomic status groups. Health education should be strengthened among residents, especially among the manual workers class, low education class and low income class.
