Objective To explore the family adaptability and cohesion in cerebral palsy children.Methods A total of 225 children were selected in two hospitals of Anhui province from May to November in 2014.Their parents or family primary caregivers were interviewed using Family Adaptability and Cohesion Scale,Second Edition-Chinese version (FACESII-CV) and self-designed general information questionnaire.Results The actual family types of 225 cerebral palsy children families were:102 cases of intermediate type (45.3％),76 cases of extreme type (33.8％),47 cases of balance type (20.9％),while the ideal family types were:92 cases of intermediate type (40.9％),62 cases of extreme type (27.6％),71 cases of balance type (31.5％),it was significant between the actual and the ideal family types (x2=6.817,P＜0.05).The actual and ideal scores of family adaptability and cohesion scale were (64.09 ± 12.23) points,(43.28 ± 9.91) points and (73.91 ± 9.31) points,(52.73 ± 7.16) points,respectively,the difference was significant (t=-9.049,-10.976,P＜0.01).The scores in the family which the mother had a higher culture degree (F=7.075,8.499,P＜0.01),the cerebral palsy children did not live with grandparents (t=5.925,4.138,P＜0.05),the one-child family (t=5.370,4.652,P＜0.05) were higher.Conclusions The relationship between family members are estranged in most cerebral palsy children families,the ability of family coping with stuff is low and the family function is poor,in addition,the family adaptability and cohesion are mainly affected by the mother's culture degree,whether live with grandparents,the number of children.All above these are need to be intervented early to improve family function.

BACKGROUND:Currently, there is a lack of efficient, non-invasive way to transplant stem cels to the target organ or tissue. Exploring a way to guide targeting transplantation of stem cels and to improve the efficiency of stem cel homing is now one of focuses in the field of stem cels research.
OBJECTIVE: To establish a simple and feasible method to chemicaly modify the cel surface using biotin-streptavidin reaction system, and to evaluate the efficiency of this method to label bone marrow mesenchymal stem cels (BMSCs) and its effects on cel biological functions.
METHODS: Passage 3 BMSCs were obtained by whole bone marrow culture method and verified by flow cytometry. Biotin, streptavidin, sulfonated biotin-N-hydroxy-succinimide were used to equip the adhesion molecule ligand, sialyated LewisX (SLeX), to the BMSCs surface. The labeling rate of BMSCs was assessed using fluorescence microscope, the vitality of BMSCs was evaluated by trypan blue staining, and the proliferation of BMSCs was evaluated by cel counting kit-8 assay. Adipogenic and osteogenic inductions were used to evaluate the effect of the method on the multi-differentiation function of BMSCs.
RESULTS AND CONCLUSION: After culture for 2 weeks, passage 3 BMSCs were obtained and confirmed by expressing CD90, CD29 and lack of CD34, CD45. Biotin, streptavidin, sulfonated biotin-N-hydroxy-succinimide were successfuly used to equip sialyated LewisX (SLeX) to the BMSCs surface and had minor effects on the vitality, proliferation, and differentiation of BMSCs. This method was simple for surface modification and had a high modification rate of 88%. The homing of BMSCs modified by this method to the target organ or tissue could be greatly enhanced. Therefore, this method potentialy could have extensive and important applications.

Objective To provide the anatomical basis for the flap based on the perforator of Plantar arch,through investigation of the morphological features of the perforator of the arch of the foot.Methods From November,2015 to March,2016,the first metatarsal base and the fifth metatarsal tuberosity were chosen as the observation point on 25 specimens of adult human feet perfused with red latex.The following contents were observed under surgical magnifier:①The origin,courses,branches and distribution of the perforator of Plantar arch.②The anastomoses among the perforator of Plantar arch and the fete arteriosum dorsale pedis.Mimic operation was performed on another fresh specimen perfused with red latex.Results There were 3 perforators in Plantar arch,which passed through the 2nd-4th metatarsal dorsal muscles to the dorsi pedis and then divided into an ascending branch and a descending branch.The ascending branch anastomosed with the rete arteriosum dorsale pedis,and the descending branch stretched to the 2nd-4th plantar arteries.The initiative outer diameters of the 1st-3rd dorsal perforators of Plantar arch were (1.5 ± 0.3)mm,(1.1 ± 0.4) mm and (0.9-± 0.3) mm respectively,and the lengths of the stem were (1.1 ± 0.2) cm,(1.5 ± 0.1) cm and (1.5 ± 0.5) cm respectively.Conclusion The flap can be used for repair of soft-tissue defects of dorsal and front foot through dorsal transposition or a V-Y advancing flap with the perforator of Plantar arch as its vascular pedicle.

Objective Treatment and histopathological observation of demodex canis in beagle dogs .Methods Using the method of direct smear for microscopic examination of demodex canis.Histopathological observation on the skin of the parasitic parts after routine paraffin section and HE staining .Results (1) Clinical observation: The red spots and hair removal was appeared on limbs , eyes, lower abdomen and other parts of the skin of canine patients .The skin of the limbs becomes thicker and wrinkles .(2) Blood routine examination:Basically normal.(3) Microscope observation:The results showed that a large number of worms and eggs of small demodex canis could be found .(4) Histopathological observation:Hair follicles showed a large number of demodex mites and eggs.The sebaceous glands and sweat glands have normal morphology and no mites was found .A large number of eosinophils and neutrophil infiltration were seen around the hair follicles.It was also found that the formation of multifocal granuloma:the granuloma was oval shaped .(5) Treatment programme:The combination of medication and the strengthening of environmental control has been shown to be effective . Conclusions Granuloma caused by demodex canis can be divided into immune granuloma .It may not be possible to destroy the sebaceous glands after infection with small demodex canis.Whether the sebaceous gland is infected with the demodex canis may be associated with the worm species or course of disease .

Objective: The etiology of schizophrenia is unknown and is associated with abnormal spontaneous brain activity. There are no consistent results regarding the change in spontaneous brain activity of people with schizophrenia. In this study, we determined the specific changes in the amplitude of low-frequency fluctuation/fractional amplitude of low-frequency fluctuation (ALFF/fALFF) and regional homogeneity (ReHo) in patients with drug-naïve first-episode schizophrenia (Dn-FES). Methods: A comprehensive search of databases such as PubMed, Web of Science, and Embase was conducted to find articles on resting-state functional magnetic resonance imaging using ALFF/fALFF and ReHo in schizophrenia patients compared to healthy controls (HCs) and then, anatomical/activation likelihood estimation was performed. Results: Eighteen eligible studies were included in this meta-analysis. Compared to the spontaneous brain activity of HCs, we found changes in spontaneous brain activity in Dn-FES based on these two methods, mainly including the frontal lobe, putamen, lateral globus pallidus, insula, cerebellum, and posterior cingulate cortex. Conclusion We found that widespread abnormalities of spontaneous brain activity occur in the early stages of the onset of schizophrenia and may provide a reference for the early intervention of schizophrenia.

Long-chain dicarboxylic acid (DCA), a building block for synthesizing a variety of high value-added chemicals, has been widely used in agriculture, chemical, and pharmaceutical industries. The global demand for DCA is increasing in recent years. Compared with chemical synthesis which requires harsh conditions and complicated processes, fermentative production of DCA has many unparalleled advantages, such as low cost and mild reaction conditions. In this review, we summarized the chemical and microbial synthesis methods for DCA and the commercialization status of the fermentation process. Moreover, the advances of using molecular and metabolic engineering to create high-yielding strains for efficient production of DCA were highlighted. Furthermore, the challenges remaining in the microbial fermentation process were also discussed. Finally, the perspectives for developing high titer DCA producing strains by synthetic biology were proposed.
