Abstract
The retrospective study included 122 cases of multiple glioma and 183 cases of single glioma. Of these, there were 74 males and 48 female with multiple gliomas, aged 18 to 83 (53±13) years, and 104 males and 79 females with single gliomas, aged 10 to 84 (51±14) years. A standard spatial-based lesion analysis method was used for constructing a spatially distributed frequency heatmap of multiple gliomas, to observe the characteristics of their white matter invasion sites. The spatial distribution was more frequent in the subventricular zone, corpus callosum and cingulate gyrus in the multiple glioma group compared to the single glioma group (P<0.001).The white matter areas of multiple gliomas were more extensively involved, with more frequent involvement of the conjoined fibers (corpus callosum, P<0.05) and contact fibers (cingulate, dome, 0.05<P<0.10) areas.The spatial distribution of the brain and the white matter invasion of multiple gliomas have certain site specificity.

Abstract
Objective: To investigate the early clinical outcomes of hip anterior short incision and open reduction and internal fixation for the treatment of children with Delbet Ⅱ femoral neck fracture. Methods: A retrospective analysis of 12 children with DelbetⅡ femoral neck fractures was performed with the anterior short incision approach at Department of Pediatric Orthopaedic, Children's Hospital, Nanjing Medical University from January 2014 to August 2016. There were 7 males and 5 females including 8 cases at left side and 4 cases at right side,aged (11.5±0.8) years (range: 8-14 years).Patients underwent surgery in (12.0±0.9) hours (range: 6-20 hours) after the injury. Displaced fractures were treated by open reduction if closed reduction failed.The surgical incision was performed with the anterior inferior iliac spine centered on, extending along the groin crease, and the length was 3 to 4 cm. The interval between the sartorius and the tensor fascia latae was applied, and the direct and indirect head of rectus femoris were resected to visualize the hip joint capsule. T-shaped incision was made in the capsule. After the reduction was obtained, two or three compression canulated screws were used to fix the fracture site. The healing time, complications and corresponding record outcome by X-ray and clinical examination were recorded. At the latest follow-up,the results were analyzed using the Ratliff criteria and clinical outcomes were assessed by pain, restrictive hip movement, normal activity or the avoidance of games, and the femoral neck in the radiograph. Results: Twelve patients had been followed-up for (30.0±4.1)months(range: 24-36 months). X-ray showed the fractures' healing time was (8.0±0.4) weeks(range: 7-9 weeks). Ten of the 12 fractures healed after one operation and were associated with no evidence of osteonecrosis of the femoral head. One case occurred premature physeal closure. There were no cases with fracture relocation, coaxvara, delayed union and nonunion or any significant postoperative complications. There was no infection, flexible internal fixation or ruptures. According to Ratliff grade, 9 cases of 12 patients were fine and 3 cases was acceptable. Conclusions: Satisfactory short-term effects can be achieved by a mini-incision on the anterior hip for Delbet Ⅱ pediatric femur neck fractures. The anterior incision has the advantage of less trauma, smaller incision scar, better fracture reduction and fixation, and less wound complications.

Abstract
Fluoride, which is often added to toothpaste or mouthwash in order to protect teeth from decay, may be a novel therapeutic approach for acceleration of periodontal regeneration. Therefore, we investigated the effects of fluoride on proliferation and mineralization in human periodontal ligament cells in vitro. The periodontal ligament cells were stimulated with various concentrations of NaF added into osteogenic inductive medium. Immunohistochemistry of cell identification, cell proliferation, alkaline phosphatase (ALP) activity assay, Alizarin red S staining and quantitative real-time-polymerase chain reaction (RT-PCR) were performed. Moderate concentrations of NaF (50-500 μmol/L) had pro-proliferation effects, while 500 μmol/L had the best effects. ALP activity and calcium content were significantly enhanced by 10 μmol/L NaF with osteogenic inductive medium. Quantitative RT-PCR data varied in genes as a result of different NaF concentrations and treatment periods. We conclude that moderate concentrations of NaF can stimulate proliferation and mineralization in periodontal ligament cells. These in vitro findings may provide a novel therapeutic approach for acceleration of periodontal regeneration by addition of suitable concentrations of NaF into the medication for periodontitis treatment, i.e., into periodontal packs and tissue patches.

Abstract
Objective: To clarify the age patterns and types of differences so as to provide reference on prevention and interventions of hand, foot and mouth disease (HFMD) cases, in Hubei province. Methods: We collected the HFMD case information of Hubei province from the Chinese National Notifiable Infectious Disease Reporting System in 2009-2015 while the information on pathogens from the laboratory monitoring system of Center for Disease Control and Prevention at all levels in Hubei province. All the data were stratified by age, disease severity, laboratory confirmation status, and serotypes of enterovirus. Results: There were 495 783 reported HFMD cases from 2009 to 2015, in Hubei province, of which 1 045 were severe with 99 fatal. The annual notification rate was 1 231.0/10(6). HFMD cases were concentrated mainly in 0.5-5 year olds, with highest severity and mortality seen in 6-11 month-olds. The predominated pathogen in mild laboratory-confirmed cases each year, in order during 2009-2015 as: EV71, Cox A16, Cox A16, Cox A16, EV71, Cox A16 and other EV. HFMD showed semiannual peaks in April-June, November-December, and with more cases in the even years than in the odd years. Conclusions: Children aged 0.5 to 5 years with 6 to 11 month-olds in particular, were the focused groups of attention in Hubei province. Our findings provided evidence for the improvement on monitoring program. Targeted intervention approaches should be strengthened to reduce the mortality and morbidity of HFMD in the province.

Abstract
OBJECTIVE To summarize surgical experience during the conduction of robotic mitral valve repair and evaluate the long-term follow-up results. METHODS From January 2007 to September 2014, 110 consecutive patients underwent robotic mitral valve repair under da Vinci Surgical System (Intuitive Surgical, USA) in Chinese PLA General Hospital were enrolled. The age of the patients was 14 to 65(45±12) years old. The male to female ratio was 2.3∶1. Among them, 95.5%(105/110) of the cases was diagnosed as mitral regurgitation and 4.5%(5/110) of them was diagnosed as mitral stenosis, and most of them (63.3%) needed triangular or quadrangular resection. Nitinol U-clips (58.1%), running suture (31.2%) and Cor-Knot™ suture device (10.8%) were used to secure the annuloplasty ring. The operative data were collected and patients were regularly followed up echocardiographically as long as 7 years. RESULTS All the surgeries were finished by the same surgeon. One case required conversion to sternotomy. The mean cardiopulmonary bypass (CPB) and cross-clamp time was 70 to 152 (121.0±34.3) and 47 to 122 (82.6±25.3) minutes respectively. After surgery, one death (0.91%) and two cases of stroke (1.82%) occurred. Three cases of early prosthetic failure (2.73%) were noticed. All patients were successfully followed up for a median of 50 (range, 1 month to 7 years) months and 94.5%(104/110) of them had no re-operation. CONCLUSION Robotic mitral valve repair is a safe and effective surgical method with excellent long-term outcomes.

Abstract
The exotoxin SLT-IIeB from the Escherichia coli Ee strain was expressed in E. coli, and the recombinant protein was purified, mixed with the Ee strain, then emulsified with oil-emulsion adjuvants to obtain a mixed subunit bacterin. Groups of Kunming mice were immunized at weeks 0 and 2, and challenged intraperitoneally with the Ee strain at week 4. Antibodies were detected by ELISA and an agglutination test. After the second immunization, the antibody level increased and the rate of immune protection against the Ee strain was 70 and 91.7% in the subunit bacterin and bacterin groups, respectively. Therefore, the mixed subunit bacterin provided good protection against the homologous Ee strain, which provides a basis for further research, into high-efficacy vaccines against porcine edema disease.

Abstract
Five fresh tibias removed from 30-40 years old dead males were osteotomized at one-third supra-medium segment and then fixed by an unilateral adjustable external fixator (UAEF) to be used as a model of external fixation of tibial fracture. For each loading test under different configurations of UAEF, the ratio of the force-displacement was used to determine its stiffness value. The weakest mode of the UAEF device is in AP bending. Under each mode of compression, distraction, anteroposterial and lateral bending and torsion loading, increasing the pin number or pin diameter or pin separation, and/or reduction of pin group separation can significantly increase the stiffness values of UAEF (P < 0.01). These data revealed that UAEF is suitable for the external fixation of tibial fracture.

Abstract
We have proposed (Randall, L. L., and Hardy, S. J. S. (1986) Cell 46, 921-928) that during export of protein from Escherichia coli, there is a kinetic partitioning between the pathway that leads to productive translocation and the pathway that leads to folding of precursors into a stable conformation that is incompatible with export. This model predicts that a decrease in rate along the productive pathway resulting from a defect in the leader sequence could be partially overcome by slowing the folding of the precursor and thereby increasing the time during which that polypeptide would be competent to enter the export pathway. Here it is shown that a change in the mature portion of maltose-binding protein that is known to suppress a mutation in the leader sequence (Cover, W. H., Ryan, J. P., Bassford, P. J., Jr., Walsh, K. A., Bollinger, J., and Randall, L. L. (1987) J. Bacteriol. 169, 1794-1800) also decreases the rate of folding of the precursor.
