Objective To explore the impact and protective mechanisms of head cooling on neural activity during passive hyperthermia.Methods Sixteen subjects were randomly exposed for 1 h to three different conditions: normal (25℃), hot (50℃) and head cooling (chamber:50℃,cold packs:5℃),after environment exposure, rs-fMRI were performed.Regional homogeneity(ReHo) datum at three different conditions were analyzed by REST2.0 to obtain brain areas with statistical difference.Brain voxel with statistical difference were selected as ROIs to ReHo values and were analyzed by One-Way ANOVA with SPSS18.0.Neural activity of brain areas with statistical difference were compared in any two groups by Post hoc.Results The brain regions showing differences among three groups included right orbital frontal cortex,left middle frontal gyrus,bilateral amygdala,left middle temporal gyrus,left hippocampus,bilateral parietal inferior, left precentral gyrus.Compared with normal group, ReHo increased in right orbital frontal cortex, and decreased in left precentral gyrus,left middle frontal gyrus,left parietal inferior,but no changed in bilateral amygdala,left middle temporal gyrus,left hippocampus,right parietal inferior in head cooling group.Compared with hot group,head cooling group showed increased ReHo in left middle temporal gyrus,left hippocampus,right parietal inferior,and decreased ReHo in bilateral amygdala,left parietal inferior,unchanged ReHo in right orbital frontal cortex, left precentral gyrus, left middle frontal gyrus.Conclusion The specified alterations of ReHo may reflect that the head cooling could partially eliminate the impact of passive hyperthermia, and is closely linked with emotional function.

Objective To analyze the clinical effects of the diverse prevention strategies on donation after citizen's death (DCD) donor fungal infection.Methods A retrospective study was performed on the clinical data of the antifungal preventive scheme to 261 DCD donors from January 2015 to August 2015 (the first period) and September 2015 to December 2016 (the second period) in Tongji Hospital.During the first period,the donors were administrated by ICU doctors and the antifungal agents were not applied as routine.The processes of organ procurement and trim were in accordance with the past experience.During the second period,the donor maintenance was reinforced,including antifungal preventive scheme,aseptic manipulation of organ procurement and rinsing and immersing allografts with broad-spectrum antibiotics or diluting povidone-iodine solutions during organ trim.Microbial culture specimens were performed in 1 574 samples including blood samples,perfusion fluids and arterial tissues and the pathogen distribution at the different periods was identified.Result In the microbial culture specimens of 1 574 samples,907 strains of pathogens were detected,including 799 strains of bacteria and 108 strains of fungi.The positive rate of fungi was 12.0％ (108/907) of all pathogens,and 17.3％ (108/626) of fungal cultures specimens.The fungi positive rate in the second period (13.6％,59/433) was significantly lower than that in the first period (25.4％,49/193,P＜ 0.05).Conclusion It is essential to reduce the incidence of donor fungal infection by increasing the microbial cultures and antifungal preventive scheme.And it is necessary that the organ procurement organization team enhances the risk awareness of donor-derived fungal infection and improves the aseptic manipulation of organ procurement.Additionally,rinsing and immersing allografts with broad-spectrum antibiotics or diluting povidone-iodine solutions may be a better option for preventing the donor-derived fungal infection during the allograft trim.

AIM To investigate the clinical therapeutic effects of modified Shenqi Decoction in treating earlyto-middle stage nontraumatic osteonecrosis of femoral head (NONFH) due to kindey deficiency and blood stasis syndrome,and its impacts on serum TNF-α,CRP,NO,SOD as well.METHODS Totally,104 cases of eligible patients were randomly divided into traditional Chinese medicine (TCM) group,chemical medicine group and TCM combined with chemical medicine group,38 cases in each group,for a three-month course of treatment.The TCM group was dosed with modified Shenqi Decoction,the chemical medicine group with sodium alendronate,and the TCM combined with chemical medicine group with both modified Shenqi Decoction and sodium alendronate.The Harris SF-36,SF-36,FPS-R and TCM symptoms assessment were applied to estimating the efficacy of three groups before and after the treatment.So were the check of the serum TNF-α,CRP,NO,SOD levels,and rates of efficiency after treatments and six-month follow-ups,and incidence of adverse reactions during the treatment among all the three groups.RESULTS The efficiency rates were found to be in the following sequence:the chemical medicine group (76.5％) ＜ the TCM group (83.8％) ＜ the TCM combined with chemical medicine group (97.2％) (P ＜ 0.05).The TCM combined with chemical medicine group had its post-treatment scores of Harris SF-36,FPS-R,FPS-R,TCM symptom and the serum TNF-α,CRP,NO,SOD levels significantly improved as compared with other two groups (P ＜ 0.05).And the revealed incidence of adverse reactions was ranked as the TCM group (2.7％) ＜ the TCM combined with chemical group (30.6％) ＜ the chemical medicine group (70.6％) (P ＜ 0.05).CONCLUSION Modified Shenqi Decoction is superior to sodium alendronate in the treatment of NONFH due to kidney deficiency and blood stasis syndrome for its better performance in both the efficacy and the incidence of adverse reactions,and its synergistic effect with use of sodium alendronate may associate with its capability in offsetting the adverse reactions of sodium alendronate.

OBJECTIVETo investigate genotypes of the hepatitis B virus (HBV) and alanine aminotransferase (ALT) levels of HBeAg negative patients with chronic hepatitis B and liver cirrhosis.

METHODSHBV serological markers and ALT levels were detected in 62 patients with chronic hepatitis B and 41 cases with liver cirrhosis, using enzyme linked absorbent immunoassays and an enzyme method, respectively. A polymerase chain reaction of S region was used for HBV genotyping.

RESULTSOf the 62 patients with chronic hepatitis B, 21 (33.9%) were HBeAg negative, and 41 (66.1%) HBeAg positive. Among 41 cases with liver cirrhosis, 28 (68.3%) were HBeAg negative, and 13 (31.7%) HBeAg positive. Of these 62 patients with chronic hepatitis B, 53 (85.5%) were infected with HBV genotype C, and 9 (14.5%) with genotype B. Thirty-nine (95.1%) of the 41 patients with liver cirrhosis were infected with genotype C, and 2 (4.9%) with genotype B. The proportion of HBeAg negative chronic hepatitis B patients with ALT level > 40 U/L was lower than that of the HBeAg positive group (47.6% and 85.4%, respectively) (P < 0.01). The percentage of ALT levels > 40 U/L of the negative patients with liver cirrhosis was also lower as compared to that of the HBeAg positive patients, but there was no statistical difference between the two groups, because of the small sample size (P > 0.05).

CONCLUSIONThe proportion of HBeAg negative patients is high in the group of chronic hepatitis B and liver cirrhosis. These patients have relatively low ALT levels, and mainly have HBV genotype C infection.

Aim To observe the effect of capsaicin on the experimental autoimmune neuritis (EAN) in rats and explore the mechanism.Methods To induce EAN,male Lewis rats were immunized with peripheralnerve myelin sheath antigen (P257481) peptide and complete Freund's adjuvant (CFA) mixed liquor.Rapamycin (RAPA,2.5 mg · kg-1) was administered by intraperitoneal injection 0.5 h after immunization and capsaicin (1 mg · kg-1 · d-1) was administered by intragastric administration 1.0 h after immunization for 15 days.The incidence and clinical characteristics of EAN were observed.The clinical scores of neurological signs were completed and body weight was measured.Pathological morphology of sciatic nerve was observed by HE staining and Lauck fast blue staining.Ultrastructure of sciatic nerve was observed by transmission electron microscope.Levels of serum tumor necrosis factor alpha (TNF-α),interferon gamma (IFN-γ),interleukin 1β (IL-1β) and intedeukin-6 (IL-6) were tested by enzyme linked immunosorbent assay (ELISA).Expressions of autophagy related protein were measured by Western blot.Results Compared with EAN group,the clinical scores of neurological signs significantly decreased from day 7 to day 16 of post-immunization (P ＜ 0.05),body weight significantly increased from day 3 to day 16 of post-immunization (P ＜ 0.05),demyelination obviously decreased,inflammatory cell infiltration number obviously decreased (P ＜ 0.05),the levels of TNF-α,IFN-γ,IL-1β and IL-6 significantly decreased (P ＜ 0.05),the number of autophagosome in axon of sciatic nerve significantly decreased (P ＜ 0.05),and expressions of Beclin-1 and LC3-Ⅱ and the ratio of LC3-Ⅱ and LC3-Ⅰ were significantly down-regulated,and the expression of p62 was significantly up-regulated (P ＜ 0.05) in EAN + capsaicin group.Rapamycin partially reversed the action of capsaicin.Conclusions Capsaicin inhibits EAN in rats,and the mechanism may be related with the inhibition of autophagy activity.

Salivary analysis can be used to assess the severity of caries. Of the known salivary proteins, a paucity of information exists concerning the role of proteinase 3 (PR3), a serine protease of the chymotrypsin family, in dental caries. Whole, unstimulated saliva was collected from children with varying degrees of active caries and tested using a Human Protease Array Kit and an enzyme-linked immunosorbent assay. A significantly decreased concentration of salivary PR3 was noted with increasing severity of dental caries (P<0.01); a positive correlation (r=0.87; P<0.01; Pearson's correlation analysis) was also observed between salivary pH and PR3 concentration. In an antibacterial test, a PR3 concentration of 250 ng·mL⁻¹ or higher significantly inhibited Streptococcus mutans UA159 growth after 12 h of incubation (P<0.05). These studies indicate that PR3 is a salivary factor associated with the severity of dental caries, as suggested by the negative relationship between salivary PR3 concentration and the severity of caries as well as the susceptibility of S. mutans to PR3.

OBJECTIVE: To investigate whether there is a difference in cerebellar development between appropriate -for-gestational-age (AGA) infants and small-for-gestational-age (SGA) infants. METHODS: A total of 165 AGA infants and 105 SGA infants, with a gestational age of 26-40 weeks, were enrolled in this study. Within 24-48 hours after birth, ultrasound examination was performed to measure the transverse diameter of the cerebellum, the height of the vermis, the area of the vermis, the perimeter of the vermis, and the area and perimeter of the cerebellum on transverse section. A Pearson correlation analysis was used to investigate the correlation between cerebellar measurements and gestational age. RESULTS: In both AGA and SGA infants, all cerebellar measurements were positively correlated with gestational age (r=0.50-0.81, P<0.05). In AGA and SGA infants, there were no significant differences in the measurements between the 25-27 weeks, 28-30 weeks, and 31-33 weeks of gestational age subgroups (P>0.05), while in the 34-36 weeks and 37-40 weeks subgroups, the SGA infants had significantly lower measurements than the AGA infants (P<0.05). CONCLUSIONS The SGA infants with a gestational age of <34 weeks have intrauterine cerebellar development similar to AGA infants, but those with a gestational age of ≥34 weeks have poorer intrauterine cerebellar development than AGA infants.
