Objective: On the basis of the dominant frequency index of functional connectivity, the "brain age" analysis method was used to explore abnormal development patterns of sensorimotor networks in boys with autism spectrum disorder(ASD). Methods: The resting state functional magnetic resonance data (7-12 years old) for 105 boys with ASD and 102 matched boys with normal development from the ABIDE public database were screened. Functional connection networks in different frequency bands of sensorimotor related brain regions were constructed for each individual, and the frequency of the strongest connection were constructed as the optimal frequency of the connection. Brain age analysis was used to explore the difference between brain age and chronological age in boys with ASD. Results: The brain sensorimotor network of boys with ASD showed an abnormal development pattern of overdevelopment followed by underdevelopment, and the transition between the two patterns occurred at approximately 7.8 years of age. Older boys with ASD (older than 10 years) whose underdevelopment trend was suppressed had lower ASD severity( r=-0.43, P < 0.05 ). Conclusion The brain sensorimotor network in boys with ASD has an abnormal development process, and the brain chronological age difference in the sensorimotor network has potential as a neuroimaging marker to measure the development of ASD.

AIMTo investigate the preventive effects of Panax notoginseng saponins (PNS) and Ginkgo biloba extracts (GbE) on acute oxygen toxicity and the possible mechanisms.

METHODSMice were injected intraperitoneally with PNS and GbE for 5 days, then were exposed to 500 kPa hyperbaric oxygen (HBO) for 60 min, the convulsion latency, times and interval were observed. Moreover, reactive oxygen (RO) unit, MDA, NO, GSH levels and GSH-Px, CAT, MAO activities of mice brain were determined after they were exposed to HBO for 15 min.

RESULTSPNS and GbE could markedly prolong the convulsion latency and interval, reduce convulsion times, decrease contents of MDA and NO in mice brain, keep RO unit, GSH and GSH-Px at higher levels, but had no effects on CAT and MAO activities.

CONCLUSIONPNS and GbE could effectively prevent acute oxygen toxicity, which were related to their antioxidant activities.

To test the hypothesis that concentration polarization of atherogenic lipids may occur in the arterial system and play an important role in localization of atherosclerosis, we simulated and measured in vitro the luminal surface concentration of low density lipoprotein (LDL) in local stenosis at the distal end of carotid artery by number simulation and laser scanning confocal microscopy, then we designed carotid stenosis model to test the role of LDL concentration polarization in atherogenesis. The in vitro experiment showed that the luminal surface LDL concentration was higher than the bulk concentration as predicted by the concentration polarization theory. The relative luminal surface LDL concentration changed with the flow velocity and ratio of stenosis. The wall concentration of LDL was highest in the round tube with 40% stenosis at the same velocity, while the wall concentration of LDL was higher when Re was 250 than Re was 500 at the same extent of narrowness. The animal experiment also revealed that general atherogenic plaques obviously occurred at the distal end of local stenosis where concentration polarized. The results strongly support our hypothesis that concentration polarization of lipoproteins occurs in local stenosis at the distal end of carotid artery, and this in turn promotes the localization of atherosclerosis which develops in the arterial system.

BACKGROUNDOur previous study had demonstrated that ulinastatin (UTI) had a neuroprotective effect in experimental autoimmune encephalomyelitis (EAE). Methylprednisolone has been recommended to be a standard drug in multiple sclerosis (MS) therapies. The present study was to investigate the protective effects of UTI combined methylprednisolone in EAE.

METHODSMice were divided into a UTI treatment group, a methylprednisolone treatment group, a combined treatment group with UTI and methylprednisolone, a normal saline treatment group, and a normal control group. EAE mice were induced in groups receiving different combined treatments, or respective monotherapies. Demyelination was evaluated by Solochrome cyanin staining. 2',3'-cyclic nucleotide 3'-phosphodiesterase (CNP)/ myelin basic protein (MBP)/ the precursor form of nerve growth factor (proNGF)/p75/ inducible nitric oxide synthase (iNOS) proteins in cerebral cortex of EAE were detected by Western blotting.

RESULTSThe combined treatment group had a lower clinical score (0.61 ± 0.06) and demyelinating score (1.33 ± 0.33) than the groups with normal saline (clinical score: 1.39 ± 0.08, P < 0.001; demyelinating score: 2.75 ± 0.49, P < 0.05) or monotheraphies. Compared with the saline treated EAE group, UTI combined methylprednisolone significantly increased expressions of CNP (1.14 ± 0.06 vs. 0.65 ± 0.04, P < 0.001), MBP (1.28 ± 0.14 vs. 0.44 ± 0.17, P < 0.001), and decreased expressions of proNGF (1.08 ± 0.10 vs. 2.32 ± 0.12, P < 0.001), p75 (1.13 ± 0.13 vs. 2.33 ± 0.17, P < 0.001), and iNOS (1.05 ± 0.31 vs. 2.17 ± 0.13, P < 0.001) proteins in EAE. Furthermore, UTI combined methylprednisolone could significantly upregulate MBP (1.28 ± 0.14 vs. 1.01 ± 0.15, P < 0.05) expression and downregulate iNOS (1.05 ± 0.31 vs. 1.35 ± 0.14, P < 0.05) expression compared to methylprednisolone treatment EAE group. And proNGF expression was significantly lower in combined treatment (1.08 ± 0.10) than that in UTI (1.51 ± 0.24, P < 0.05) or methylprednisolone (1.31 ± 0.04, P < 0.05) treatment group.

CONCLUSIONCombination treatment of UTI with methylprednisolone was shown to protect EAE, suggesting that combination therapy is a potential novel treatment in MS.

OBJECTIVEIn mid-July 2005, five patients presented with septic shock to a hospital in Ziyang city in Sichuan, China, to identify the etiology of the unknown reason disease, an epidemiological, clinical, and laboratory study were conducted.

METHODSAn enhanced surveillance program were established in Sichuan, the following activities were introduced: active case finding in Sichuan of (a) laboratory diagnosed Streptococcus suis infection and (b) clinically diagnosed probable cases with exposure history; supplemented by (c) monitoring reports on meningococcal meningitis. Streptococcus suis serotype 2 infection was confirmed by culture and biochemical reactions, followed by sequencing for specific genes for serotype and virulence factors.

RESULTSFrom June 10 to August 21, 2005, 68 laboratory confirmed cases of human Streptococcus suis infections were reported. All were villagers who gave a history of direct exposure to deceased or sick pigs in their backyards where slaughtering was performed. Twenty six (38%) presented with toxic shock syndrome of which 15 (58%) died. Other presentations were septicaemia or meningitis. All isolates were tested positive for genes for tuf, species-specific 16S rRNA, cps2J, mrp, ef and sly. There were 136 clinically diagnosed probable cases with similar exposure history but incomplete laboratory investigations.

CONCLUSIONAn outbreak of human Streptococcus suis serotype 2 infections occurred in villagers after direct exposure to deceased or sick pigs in Sichuan. Prohibition of slaughtering in backyards brought the outbreak to a halt. A virulent strain of the bacteria is speculated to be in circulation, and is responsible for the unusual presentation of toxic shock syndrome with high case fatality.

The aim of this research is to investigate the effects of paeoniflorin and menthol on the physiological function of Calu-3 cell membrane during the transport of puerarin. Calu-3 cell was used as the cell model to simulate nasal mucosa tissues, and the cell membrane fluidity, Na⁺-K⁺-ATPase activity and Ca²⁺-ATPase activity were detected by fluorescence recovery after photobleaching(FRAP) and ultramicro enzyme activity testing, in order to explore the mechanism of compatible drugs on promoting puerarin transport. The results showed that when puerarin associated with low, middle and high concentration of menthol or both paeoniflorin and menthol, the fluorescence recovery rate was increased significantly, while Na⁺-K⁺-ATPase activity had no significant change and Ca²⁺-ATPase activity was enhanced significantly as compared with puerarin alone. Therefore, it was concluded that menthol had the abilit of promoting the transport and the mechanism might be related to increasing membrane fluidity and activating Ca²⁺-ATPase.

OBJECTIVE: To observe the therapeutic effect between acupuncture combined with medication and simple medication on migraine and cerebral hemodynamics. METHODS: A total of 120 patients with migraine were randomized into an acupuncture plus medication group (60 cases, 3 cases dropped off) and a medication group (60 cases, 6 cases dropped off). In the medication group, flunarizine hydrochloride capsule was given orally before sleep, 10 mg a day. On the basis of the treatment in the medication group, acupuncture was applied at Sizhukong (TE 23), Shuaigu (GB 8), Taiyang (EX-HN 5), Fengchi (GB 20) and etc. in the acupuncture plus medication group, 30 min each time, once a day. Treatment for 4 weeks was required in both groups. Before and after treatment, the visual analogue scale (VAS) score, indexes of cerebral hemodynamic [blood flow velocity of anterior cerebral artery (ACA), middle cerebral artery (MCA), posterior cerebral artery (PCA), vertebral artery (VA) and basilar artery (BA)] and total TCM syndrome score were observed, and the clinical therapeutic effect and the incidence of the adverse events were evaluated in both groups. RESULTS: Compared before treatment, the VAS scores, the blood flow velocity of ACA, MCA, PCA, VA, BA and the total TCM syndrome scores were decreased in both groups ( CONCLUSION Acupuncture combined with flunarizine hydrochloride capsule can effectively relieve the pain in patients with migraine, reduce the cerebral blood flow velocity, the efficacy is superior to simple flunarizine hydrochloride capsule.
