Treatment determination based on syndrome differentiation is the key of Chinese medicine. A feasible way of improving the clinical therapy effectiveness is needed to correctly differentiate the syndrome classifications based on the clinical manifestations. In this paper, a novel data mining method based on manifold ranking (MR) is proposed to explore the relation between syndromes and symptoms for viral hepatitis. Since MR could take the symptom data with expert differentiation and the symptom data without expert differentiation into the task of syndrome classification, the clinical information used for modeling the syndrome features is greatly enlarged so as to improve the precise of syndrome classification. In addition, the proposed method of syndrome classification could also avoid two disadvantages in previous methods: linear relation of the clinical data and mutually exclusive symptoms among different syndromes. And it could help exploit the latent relation between syndromes and symptoms more effectively. Better performance of syndrome classification is able to be achieved according to the experimental results and the clinical experts.

BACKGROUNDFunctional electrical stimulation (FES) is known to promote the recovery of motor function in rats with ischemia and to upregulate the expression of growth factors which support brain neurogenesis. In this study, we investigated whether postischemic FES could improve functional outcomes and modulate neurogenesis in the subventricular zone (SVZ) after focal cerebral ischemia.

METHODSAdult male Sprague-Dawley rats with permanent middle cerebral artery occlusion (MCAO) were randomly assigned to the control group, the placebo stimulation group, and the FES group. The rats in each group were further assigned to one of four therapeutic periods (1, 3, 7, or 14 days). FES was delivered 48 hours after the MCAO procedure and divided into two 10-minute sessions on each day of treatment with a 10-minute rest between them. Two intraperitoneal injections of bromodeoxyuridine (BrdU) were given 4 hours apart every day beginning 48 hours after the MCAO. Neurogenesis was evaluated by immunofuorescence staining. Wnt-3 which is strongly implicated in the proliferation and differentiation of neural stem cells (NSCs) was investigated by Western blotting analysis. The data were subjected to one- way analysis of variance (ANOVA), followed by a Tukey/Kramer or Dunnett post hoc test.

RESULTSFES significantly increased the number of BrdU-positive cells and BrdU/glial fibrillary acidic protein double- positive neural progenitor cells in the SVZ on days 7 and 14 of the treatment (P < 0.05). The number of BrdU/doublecortin (DCX) double-positive migrating neuroblast cells in the ipsilateral SVZ on day 14 of the FES treatment group ((522.77 ± 33.32) cells/mm(2)) was significantly increased compared with the control group ((262.58 ± 35.11) cells/mm(2), P < 0.05) and the placebo group ((266.17 ± 47.98) cells/mm(2), P < 0.05). However, only a few BrdU/neuron-specific nuclear protein-positive cells were observed by day 14 of the treatment. At day 7, Wnt-3 was upregulated in the ipsilateral SVZs of the rats receiving FES ((0.44 ± 0.05)%) compared with those of the control group rats ((0.31 ± 0.02)%, P < 0.05) or the placebo group rats ((0.31 ± 0.04)%, P < 0.05). At day 14, the corresponding values were (0.56 ± 0.05)% in the FES group compared with those of the control group rats ((0.50 ± 0.06)%, P < 0.05) or the placebo group rats ((0.48 ± 0.06)%, P < 0.05).

CONCLUSIONFES augments the proliferation, differentiation, and migration of NSCs and thus promotes neurogenesis, which may be related to the improvement of neurological outcomes.

Objective: Whether metabolic redistribution occurs in patients with white matter hyperintensities (WMHs) on magnetic resonance imaging (MRI) is unknown. This study aimed 1) to propose a measure of the brain metabolic network for an individual patient and preliminarily apply it to identify impaired metabolic networks in patients with WMHs, and 2) to explore the clinical and imaging features of metabolic redistribution in patients with WMHs. Materials and Methods: This study included 50 patients with WMHs and 70 healthy controls (HCs) who underwent 18F-fluorodeoxyglucose-positron emission tomography/MRI. Various global property parameters according to graph theory and an individual parameter of brain metabolic network called “individual contribution index” were obtained. Parameter values were compared between the WMH and HC groups. The performance of the parameters in discriminating between the two groups was assessed using the area under the receiver operating characteristic curve (AUC). The correlation between the individual contribution index and Fazekas score was assessed, and the interaction between age and individual contribution index was determined. A generalized linear model was fitted with the individual contribution index as the dependent variable and the mean standardized uptake value (SUVmean) of nodes in the whole-brain network or seven classic functional networks as independent variables to determine their association. Results: The means ± standard deviations of the individual contribution index were (0.697 ± 10.9) x 10-3 and (0.0967 ± 0.0545) x 10-3 in the WMH and HC groups, respectively (p < 0.001). The AUC of the individual contribution index was 0.864 (95% confidence interval, 0.785–0.943). A positive correlation was identified between the individual contribution index and the Fazekas scores in patients with WMHs (r = 0.57, p < 0.001). Age and individual contribution index demonstrated a significant interaction effect on the Fazekas score. A significant direct association was observed between the individual contribution index and the SUVmean of the limbic network (p < 0.001). Conclusion The individual contribution index may demonstrate the redistribution of the brain metabolic network in patients with WMHs.

Infections by Cronobacter spp. are hazardous to infants since they can lead to neonatal meningitis, bacteremia, and necrotizing enterocolitis. Cronobacter spp. are frequently resistant to β-lactam derivatives, macrolides, and aminoglycosides. In addition, multi-resistant strains have also been detected. In China, the isolation rate of Cronobacter spp. from commercial powdered infant formula (PIF) or follow-up formula (FUF) is relatively high. Nevertheless, clinical cases of Cronobacter infection have been ignored to date. Here we describe two cases of Cronobacter infection detected at the Wuhan Women and Children Medical Care Center Hospital (Wuhan City, China). We provide the genomic analysis of the isolates and the antibiotic-resistance profiles of the two strains. The Cronobacter strains identified in this study were not susceptible to third-generation cephalosporins, aminoglycoside, and/or trimethoprim-sulfamethoxazole. Whole genome sequencing revealed various genes known to encode antibiotic resistance. Future studies are needed to determine whether the genes predicted in this study are functional. As with Enterobacter spp., the antibiotic resistance of Cronobacter is a serious issue that requires more attention.

OBJECTIVE: To evaluate the effects of auricular acupoint bloodletting (AB) and auricular acupressure (AA) on sleep quality and the levels of melatonin (MT), glutamic acid (Glu), and γ -aminobutyric acid (GABA) in college students with primary insomnia, and to explore the possible mechanism. METHODS: Totally 74 college students at Hebei University of Chinese Medicine with primary insomnia were selected from October 2019 to October 2020. All patients were assigned to AB+AA group (37 cases, received combination of AB and AA) and AA group (37 cases, received only AA on the same acupoints) by a random number table. Each group was treated twice a week for 4 weeks. The Pittsburgh Sleep Quality Index (PSQI) score, Chinese medicine (CM) syndrome score, total effective rate, serum concentrations of MT, Glu, and GABA, and Glu/GABA ratio were compared between the two groups after treatment and at follow-up. The safety of therapy was also evaluated. RESULTS: After 4-week treatment, the total scores of PSQI, each PSQI component score, and the CM syndrome scores in both groups all decreased (P<0.05); the serum MT concentrations in both groups all increased (P<0.05). The concentrations of Glu and GABA in the AB+AA group were significantly higher than those in the AA group after treatment (P<0.05). However, there was no significant difference in the ratio of Glu/GABA in both groups before and after treatment (P>0.05). At follow-up, the CM syndrome score in the AB+AA group was significantly lower than that in the AA group (P<0.05). There was no significant difference between the two groups in total effective rates and adverse events (P>0.05). CONCLUSIONS Both AB+AA and AA can relieve insomnia symptoms, but a stronger long-term effect were observed for AB+AA. AB+AA can promote the secretion of MT, increase the levels of Glu and GABA more effective than AA, and regulate their imbalance, and thus it may be benificial for treating insomnia.
