Abstract
Glioblastoma (GBM) is an extremely aggressive primary brain tumor with poor prognosis, short survival time post-diagnosis and high recurrence. Currently, no cure for GBM exists. The identification of an effective therapeutic modality for GBM remains a high priority amongst medical professionals and researches. In recent studies, inhalant cannabidiol (CBD) has demonstrated promise in effectively inhibiting GBM tumor growth. However, exactly how CBD treatment affects the physiology of these tumor cells remains unclear. Stress granules (SG) (a sub-class of biomolecular condensates (BMC)) are dynamic, membrane-less intracellular microstructures which contain proteins and nucleic acids. The formation and signaling of SGs and BMCs plays a significant role in regulating malignancies. This study investigates whether inhaled CBD may play an intervening role towards SGs in GBM tumor cells. Integrated bioinformatics approaches were preformed to gain further insights. This includes use of Immunohistochemistry and flow cytometry to measure SGs, as well as expression and phosphorylation of eukaryotic initiation factor-2α (eIF2α). The findings of this study reveal that CBD receptors (and co-regulated genes) have the potential to play an important biological role in the formation of BMCs within GBM. In this experiment, CBD treatment significantly increased the volume of TIAR-1. This increase directly correlated with elevation in both eIF2α expression and p-eIF2α in CBD treated tissues in comparison to the placebo group (p < 0.05). These results suggest that inhalant CBD significantly up-regulated SGs in GBM, and thus support a theory of targeting BMCs as a potential therapeutic substrate for treating GBM.

Abstract
Introduction: Glioblastoma (GBM) is the most common invasive brain tumor composed of diverse cell types with poor prognosis. The highly complex tumor microenvironment (TME) and its interaction with tumor cells play important roles in the development, progression, and durability of GBM. Angiogenic and immune factors are two major components of TME of GBM; their interplay is a major determinant of tumor vascularization, immune profile, as well as immune unresponsiveness of GBM. Given the ineffectiveness of current standard therapies (surgery, radiotherapy, and concomitant chemotherapy) in managing patients with GBM, it is necessary to develop new ways of treating these lethal brain tumors. Targeting TME, altering tumor ecosystem may be a viable therapeutic strategy with beneficial effects for patients in their fight against GBM. Materials and Methods: Given the potential therapeutic effects of cannabidiol (CBD) in a wide spectrum of diseases, including malignancies, we tested, for the first time, whether inhalant CBD can inhibit GBM tumor growth using a well-established orthotopic murine model. Optical imaging, histology, immunohistochemistry, and flow cytometry were employed to describe the outcomes such as tumor progression, cancer cell signaling pathways, and the TME. Results: Our findings showed that inhalation of CBD was able to not only limit the tumor growth but also to alter the dynamics of TME by repressing P-selectin, apelin, and interleukin (IL)-8, as well as blocking a key immune checkpoint-indoleamine 2,3-dioxygenase (IDO). In addition, CBD enhanced the cluster of differentiation (CD) 103 expression, indicating improved antigen presentation, promoted CD8 immune responses, and reduced innate Lymphoid Cells within the tumor. Conclusion: Overall, our novel findings support the possible therapeutic role of inhaled CBD as an effective, relatively safe, and easy to administer treatment adjunct for GBM with significant impacts on the cellular and molecular signaling of TME, warranting further research.

Abstract
Objective: To investigate the feasibility of only surgical resection for nasal vestibular squamous cell carcinoma and the efficacy of perforator flap of ipsilateral nasolabial sulcus in repairing postoperative defects. Methods: The clinical data of 8 cases with squamous cell carcinoma of the nasal vestibule who admitted to Department of Facial Plastic and Reconstructive Surgery, Eye & ENT Hospital, Fudan University were analyzed, including 6 males and 2 females, aged from 38 to 75 years. The tumor of the nasal vestibule was eradicated in time after making definite diagnosis of lesions, then the perforators flap of the ipsilateral nasolabial sulcus was used for repairment, without performing further chemotherapy or radiotherapy after surgery. The tumor recurrence, facial appearance, nostril form, donor area scar, nasal ventilation function, and cutaneous sensation were evaluated after surgery. Descriptive analysis was used in this research. Results: There were 2 cases of stage T1 and 6 cases of stage T2 in 8 cases. After 32 to 45 months of following-up, no recurrence accurred and all the flaps survived well. However, there was about 2 mm necrosis of the transplanted flap in the lateral foot of the alar in one case, which was healed well by carrying out wound care after 10 d. And the dark color flap was occurred in another case, showing the flap's backflow trouble, yet it was improved with addressing timely during 5 d postoperation. Pincusion-like deformity of the transplanted flap occurred in 4 cases (50%), which subsided gradually after 6 months. The morphology of the anterior nostril was altered in 4 cases (50%), but there was no ventilation trouble and no need for addressment in any case. The postoperative facial appearance was rated as excellentor good with hidden scar in the donor site, and the sensation of the transplanted flaps was indistinct from the surrounding tissue after 3 months. Conclusions: Surgical resection of nasal vestibular squamous cell carcinoma with tumor stage T1-2 is a feasible treatment. And it is the one of the best reconstructive methods of the perforator flap of the ipsilateral nasolabial sulcus to repair the deformities after the surgery.

Abstract
Elabela is a component of the apelinergic system and may exert a cardioprotective role by regulating the innate immune responses. Innate lymphoid cells (ILCs) have a significant role in initiating and progressing immune-inflammatory responses. While ILCs have been intensively investigated during the last decade, little is known about their relationship with the apelinergic system and their cardiac diversity in a gender-based paradigm. In this study, we investigated the polarization of cardiac ILCs by Elabela in males versus females in a mouse model. Using flow cytometry and immunohistochemistry analyses, we showed a potential interplay between Elabela and cardiac ILCs and whether such interactions depend on sexual dimorphism. Our findings showed, for the first time, that Elabela is expressed by cardiac ILCs, and its expression is higher in females' ILC class 3 (ILC3s) compared to males. Females had higher frequencies of ILC1s, and Elabela was able to suppress T-cell activation and the expression of co-stimulatory CD28 in a mixed lymphocyte reaction assay (MLR). In conclusion, our results suggest, for the first time, a protective role for Elabela through its interplay with ILCs and that it can be used as an immunotherapeutic target in the treatment of cardiovascular disorders in a gender-based fashion.

Abstract
White-eyed orbital blowout fractures in the pediatric population can present with acute onset diplopia, ophthalmalgia, and abnormal duction. These findings are attributed to the tendency of younger bone to break and reapproximate owing to greater elasticity. This phenomenon, commonly referred to as the greenstick fracture, increases the risk of entrapment of surrounding soft tissue structures in orbital floor fractures. Further concern arises in the presence of an oculocardiac reflex, which requires urgent intervention to prevent serious bradycardia. Prolonged entrapment can go unnoticed and result in irreversible ischemic damage to entrapped tissues. This case discusses the presentation 16-year-old female who sustained a left sided, white-eyed blowout fracture from a face-first ground level fall. On admission, she displayed restrictive strabismus and mild periorbital edema around the left eye. Vertical gaze was restricted when looking inferiorly on the affected side. With sustained upward gaze, her heart rate decreased from 99 to 81 beats per minute. High-resolution non-contrast computed tomography scans of the head showed entrapment of the inferior rectus muscle and periorbital fat. Liberation of entrapped tissues with reduction of bony segments was performed urgently, utilizing a MEDPOR® Titan 3D orbital floor plate and secured with two screws. The patient had an uneventful postoperative period and showed considerable improvements in periorbital edema, duction, and ophthalmalgia on the affected side. In addition, the oculocardiac reflex could no longer be elicited on prolonged upward gaze. Mild and improving paresthesia was noted in the maxillary distribution of the left trigeminal nerve. Sensory deficits like this are the result of fracture communication with the infraorbital canal, which may cause irritation of the infraorbital nerve responsible for sensation by the maxillary division. By postoperative week 7, she had complete resolution of periorbital edema, indiscernible duction abnormalities, and complete healing of surgical incision sites, and an oculocardiac reflex could not be elicited.

Abstract
Aging is a complex phenomenon associated with a wide spectrum of physical and physiological changes affecting every part of all metazoans, if they escape death prior to reaching maturity. Critical to survival, the immune system evolved as the principal component of response to injury and defense against pathogen invasions. Because how significantly immune system affects and is affected by aging, several neologisms now appear to encapsulate these reciprocal relationships, such as Immunosenescence. The central part of Immunosenescence is Inflammaging -a sustained, low-grade, sterile inflammation occurring after reaching reproductive prime. Once initiated, the impact of Inflammaging and its adverse effects determine the direction and magnitudes of further Inflammaging. In this article, we review the nature of this vicious cycle, we will propose that phytocannabinoids as immune regulators may possess the potential as effective adjunctive therapies to slow and, in certain cases, reverse the pathologic senescence to permit a more healthy aging.

Abstract
To compare changes in platelet related parameters in obese patients before and after sleeve gastrectomy (SG), we retrospectively analyzed the clinical data of 31 obese patients who underwent SG in Peking Union Medical College Hospital from December 2012 to September 2020. Results showed that compared with those before surgery, platelet count (PLT) decreased significantly at 2-12 weeks of follow-up (P=0.009), while platelet distribution width (PDW), mean platelet volume (MPV), and large platelet ratio (P-LCR) increased significantly at the same periods of follow-up after operation (P<0.001). However, the levels of PDW, MPV, and P-LCR began to decrease at 16-55 weeks when compared with those at 2-12 weeks of follow-up (P<0.01). PLT was positively correlated with white blood cells and neutrophils at 2-12 weeks of follow-up and positively correlated with high sensitivity C-reactive protein at 16-55 weeks of follow-up after operation (P<0.05).

Abstract
BACKGROUND Acute respiratory distress syndrome (ARDS) is a life-threatening clinical syndrome whose potential to become one of the most grievous challenges of the healthcare system evidenced by the COVID-19 pandemic. Considering the lack of target-specific treatment for ARDS, it is absolutely exigent to have an effective therapeutic modality to reduce hospitalization and mortality rate as well as to improve quality of life and outcomes for ARDS patients. ARDS is a systemic inflammatory disease starting with the pulmonary system and involves all other organs in a morbid bidirectional fashion. Mounting evidence including our findings supporting the notion that cannabinoids have potential to be targeted as regulatory therapeutic modalities in the treatment of inflammatory diseases. Therefore, it is plausible to test their capabilities as alternative therapies in the treatment of ARDS. In this study, we investigated the potential protective effects of cannabichromene (CBC) in an experimental model of ARDS. METHODS We used, for the first time, an inhalant CBC treatment as a potential therapeutic target in a murine model of ARDS-like symptoms. ARDS was induced by intranasal administration of Poly(I:C), a synthetic mismatched double-stranded RNA, into the C57BL/6 mice (6-10 male mice/group, including sham, placebo, and CBC treated), three once-daily doses followed by a daily dose of inhalant CBC or placebo for the period of 8 days starting the first dose 2 h after the second Poly(I:C) treatment. We employed histologic, immunohistochemistry, and flow cytometry methods to assess the findings. Statistical analysis was performed by using one way analysis of variance (ANOVA) followed by Newman-Keuls post hoc test to determine the differences among the means of all experimental groups and to establish significance (p < 0.05) among all groups. RESULTS Our data showed that CBC was able to reverse the hypoxia (increasing blood O2 saturation by 8%), ameliorate the symptoms of ARDS (reducing the pro-inflammatory cytokines by 50% in lung and blood), and protect the lung tissues from further destruction. Further analysis showed that CBC may wield its protective effects through transient receptor potential (TRP) cation channels, TRPA1 and TRPV1, increasing their expression by 5-folds in lung tissues compared to sham and untreated mice, re-establishing the homeostasis and immune balance. CONCLUSION Our findings suggest that inhalant CBC may be an effective alternative therapeutic target in the treatment of ARDS. In addition, Increased expression of TRPs cation channels after CBC treatment proposes a novel role for TRPs (TRPA1 and TRPV2) as new potential mechanism to interpret the beneficial effects of CBC as well as other cannabinoids in the treatment of ARDS as well as other inflammatory diseases. Importantly, delivering CBC through an inhaler device is a translational model supporting the feasibility of trial with human subjects, authorizing further research.

Abstract
There is a dire need for due innovative therapeutic modalities to improve outcomes of AD patients. In this study, we tested whether cannabidiol (CBD) improves outcomes in a translational model of familial AD and to investigate if CBD regulates interleukin (IL)-33 and triggering receptor expressed on myeloid cells 2 (TREM2), which are associated with improved cognitive function. CBD was administered to 5xFAD mice, which recapitulate early onset, familial AD. Behavioral tests and immunoassays were used to evaluate cognitive and motor outcomes. Our findings suggest that CBD treatment enhanced IL-33 and TREM2 expression, ameliorated the symptoms of AD, and retarded cognitive decline.

Abstract
Introduction: In addition to hand washing and wearing masks, social distancing and reducing exposure time to <15 minutes are the most effective measures against the spread of COVID-19. Unfortunately, three of these guidelines are very difficult, if not impossible, for nursing babies: they cannot wear masks, stay six feet away from the lactating breasts, nor consistently finish within 15 minutes while nursing. We report a case of a nursing mother with SARS-CoV-2 infection, documenting changes of immune cells and cytokines in breast milk with and without the infection. Case Description: With Institutional Review Board (IRB) approval, we obtained expressed breast milk samples from a lactating mother before and during SARS-CoV-2 infection as documented by reverse transcription-PCR. Using flow cytometry analysis, we measured the immune cell profiles and expression of cytokines such as interferon alpha (IFNα) in milk leukocytes before and during infection. Results: There was an eightfold increase in IFNα+ milk leukocytes, from 1% before SARS-CoV-2 infection to 8% when actively infected. The milk macrophages showed the highest increase in IFNα expression. Both T and B lymphocytes showed mild increase. Innate lymphoid cells, neutrophils, and natural killer cells showed no increase in IFNα expression and the dendritic cells actually showed a reduction. Conclusion: We document the presence and high expression of IFNα in the breast milk macrophages of a lactating mother with confirmed COVID-19, compared with her milk before the infection.

Abstract
Considering lack of target-specific antiviral treatment and vaccination for COVID-19, it is absolutely exigent to have an effective therapeutic modality to reduce hospitalization and mortality rate as well as to improve COVID-19-infected patient outcomes. In a follow-up study to our recent findings indicating the potential of Cannabidiol (CBD) in the treatment of acute respiratory distress syndrome (ARDS), here we show for the first time that CBD may ameliorate the symptoms of ARDS through up-regulation of apelin, a peptide with significant role in the central and peripheral regulation of immunity, CNS, metabolic and cardiovascular system. By administering intranasal Poly (I:C), a synthetic viral dsRNA, while we were able to mimic the symptoms of ARDS in a murine model, interestingly, there was a significant decrease in the expression of apelin in both blood and lung tissues. CBD treatment was able to reverse the symptoms of ARDS towards a normal level. Importantly, CBD treatment increased the apelin expression significantly, suggesting a potential crosstalk between apelinergic system and CBD may be the therapeutic target in the treatment of inflammatory diseases such as COVID-19 and many other pathologic conditions.

Abstract
Introduction: In the absence of effective antivirals and vaccination, the pandemic of COVID-19 remains the most significant challenge to our health care system in decades. There is an urgent need for definitive therapeutic intervention. Clinical reports indicate that the cytokine storm associated with acute respiratory distress syndrome (ARDS) is the leading cause of mortality in severe cases of some respiratory viral infections, including COVID-19. In recent years, cannabinoids have been investigated extensively due to their potential effects on the human body. Among all cannabinoids, cannabidiol (CBD) has demonstrated potent anti-inflammatory effects in a variety of pathological conditions. Therefore, it is logical to explore whether CBD can reduce the cytokine storm and treat ARDS. Materials and Methods: In this study, we show that intranasal application of Poly(I:C), a synthetic analogue of viral double-stranded RNA, simulated symptoms of severe viral infections inducing signs of ARDS and cytokine storm. Discussion: The administration of CBD downregulated the level of proinflammatory cytokines and ameliorated the clinical symptoms of Poly I:C-induced ARDS. Conclusion: Our results suggest a potential protective role for CBD during ARDS that may extend CBD as part of the treatment of COVID-19 by reducing the cytokine storm, protecting pulmonary tissues, and re-establishing inflammatory homeostasis.

Abstract
Human nutrient metabolism, developed millions of years ago, is anachronistic. Adaptive features that offered survival advantages are now great liabilities. The current dietary pattern, coupled with massively reduced physical activities, causes an epidemic of obesity and chronic metabolic diseases, such as type 2 diabetes mellitus. Chronic inflammation is a major contributing factor to the initiation and progression of most metabolic and cardiovascular diseases. Among all components of an innate immune system, due to their dual roles as phagocytic as well as antigen-presenting cells, macrophages play an important role in the regulation of inflammatory responses, affecting the body’s microenvironment and homeostasis. Earlier studies have established the beneficial, anti-inflammatory effects of whole body vibration (WBV) as a partial exercise mimetic, including reversing the effects of glucose intolerance and hepatic steatosis. Here for the first time, we describe potential mechanisms by which WBV may improve metabolic status and ameliorate the adverse consequences through macrophage polarization and altering the fecal microbiome.

Abstract
Three recent advances in immunology, genetics, and microbiology have ushered in a new era in the continued efforts to better understand and treat oral diseases, moving ever closer to the three Ps of modern healthcare: personalized, predictive, and preventive medicine (PPPM). The discovery of now 15 subtypes of innate lymphoid cells, the refinement of DNA sequencing, and culture-independent characterization of the entire microbial community begin to reveal this complex adaptive network. All these advances warrant a systematic review as they have changed and will continue to change dental medicine. We will update dental professionals on these advances as related to oral diseases and associated pathologies in other organ systems such as premature labor, arthrosclerosis, and cancer. The five objectives are:Introduce the concept of microbiota and microbiomeExplain how we study microbiota and microbiomeDescribe the types and functions of innate lymphoid cellsInventory the unique demands of the oral cavityProvide a heuristic model to integrate the aboveConclusions and expert recommendations.

Abstract
BACKGROUND Malignant melanoma is a complex malignancy with significant morbidity and mortality. The incidence continues to rise, and despite advances in treatment, the prognosis is poor. Thus, it is necessary to develop novel strategies to treat this aggressive cancer. Synthetic cannabinoids have been implicated in inhibiting cancer cell proliferation, reducing tumor growth, and reducing metastasis. We developed a unique study focusing on the effects of treatment with a cannabinoid derivative on malignant melanoma tumors in a murine model. METHODS Murine B16F10 melanoma tumors were established subcutaneously in C57BL/6 mice. Mice were then treated with intraperitoneal injections of vehicle twice per week (control-group 1, n = 6), Cisplatin 5 mg/kg/wk (group 2; n = 6), and Cannabidiol (CBD) 5 mg/kg twice per week (group 3; n = 6). Tumors were measured and volume calculated as (4π/3) × (width/2)2 × (length/2). Tumor size and survival curves were measured. Results were compared using a one-way ANOVA with multiple comparison test. RESULTS A significant decrease in tumor size was detected in mice treated with CBD when compared with the control group (P = 0.01). The survival curve of melanoma tumors treated with CBD increased when compared with the control group and was statistically significant (P = 0.04). The growth curve and survival curve of melanoma tumors treated with Cisplatin were significantly decreased and increased, respectively, when compared with the control and CBD-treated groups. Mice treated with Cisplatin demonstrated the longest survival time, but the quality of life and movement of CBD-treated mice were observed to be better. CONCLUSIONS We demonstrate a potential beneficial therapeutic effect of cannabinoids, which could influence the course of melanoma in a murine model. Increased survival and less tumorgenicity are novel findings that should guide research to better understand the mechanisms by which cannabinoids could be utilized as adjunctive treatment of cancer, specifically melanoma. Further studies are necessary to evaluate this potentially new and novel treatment of malignant melanoma.

Abstract
Many important events occur at birth. The fetus is suddenly removed from a protected intra-uterine environment that is aquatic, warm, and nearly sterile, to the dry, cold external world laden with microbes. To survive, the neonate must interact with many organisms, making use of some, while vigorously defending against the others like a nation conducting trade with friendly countries and guarding against hostile ones from invading it, waging wars if necessary. Although, the neonatal immune system is plastic, however, it is highly tolerant which is due to both the fetal development during gestation as well as significant sudden changes in fetal environment and enormous exposure to the new antigens and intestinal bacteria and their products. This “quiescent mode” of innate immune system is part of a highly regulated process to fulfill all requirements of multi-layered process of early life, implemented effectively through the cells of innate immune system. While, most of the neonatal innate immune cells (e.g., neutrophils and monocytes) present contained activity and lower frequencies compared to their adult counterparts, innate lymphoid cells (ILCs), a distinct cellular component of innate immunity, show higher level of activity and presence during period of infancy compared to later stages of life and adulthood, which may suggest a role for ILCs in variable susceptibility to certain conditions during life time. In this review, while we focus on the characteristics and status of ILCs in neonatal immune system, we also draw an analogy from a national defense perspective because of the great similarities between that and the immune system by providing the known biological counterparts of all five core operational elements, the five Ds of defense, detection, discrimination, deployment, destruction, and de-escalation, with special focus on innate immunity, maternal support, and influence during the neonatal and infancy periods.

Abstract
Objective: To explore the factors associated with illicit drug use (IDU) intention in secondary vocational school students based on theory of triadic influence (TTI), and provide theoretical foundation for IDU prevention education. Methods: A total of 8 870 students were selected from secondary vocational schools in 5 cities in China through multistage cluster sampling. A self-administered questionnaire was used to collect the information about students' sensation seeking (SS), parental monitoring (PM), perceived availability of drug (PAD), social benefit expectancies(SBE), refusal efficacy (RE) and social norms and IDU intention. Based on the TTI, the logistic regression model was used to analyze the factors associated with IDU. Results: Among the intrapersonal stream of influence, the higher levels of SS was the risk factor associated with IDU (OR=1.71, 95%CI: 1.22-2.41, P<0.01), medium RE level (OR=0.18, 95%CI: 0.14-0.23, P<0.001) and high RE level (OR=0.17, 95%CI: 0.13-0.22, P<0.001) were the protective factors for IDU intention. Among the interpersonal stream of influence, medium PM level (OR=0.46, 95%CI: 0.37- 0.56, P<0.001) and high PM level (OR=0.33, 95%CI: 0.24-0.46, P<0.001) were the protective factors for IDU intention, perceived others' drug use as well as perceived others' approval of substance use were risk factors for IDU intentions (P<0.001); Among sociocultural environmental stream of influence, perceived easy availability of drugs (OR=3.47, 95%CI: 2.69-4.48, P<0.001) and perceived SBE of drugs (OR=2.04, 95%CI: 1.69-2.46, P<0.001) were risk factors for IDU intentions (P<0.001). Conclusions: High levels of SS and SBE, perceived easier availability of substance, perceived others' substance use and perceived others' approval of substance use positively predict the students' intention of IDU. IDU prevention education for adolescents should be focused on the above factors, and parental supervision and students' refuse skills should be improved.

Abstract
Objective: To evaluate the complexity of human sagittal suture patterns and to investigate whether the suture complexity correlates with age. Design: Geometric patterns of the sagittal sutures from 104 dry human skulls from the Terry Collection and 16 computed tomography images from the Bosma Collection, aged 2 months to 60 years, were digitized. The complexity of the patterns was presented by suture length, curved suture (or skull) length, and length ratio and the frequency and amplitude contents by the discrete Fourier transform (DFT) analysis. Results: The suture length along the skull showed a positive correlation with age from 2 months to 10 years, reflecting the growth of the skull. The suture length ratio, R, a measure of the complexity of the suture pattern, had a similar trend to suture length (i.e., increased with age to about 10 years and leveled off afterward, accompanied by a large scatter). The major frequency from the DFT analysis indicated an age-related development in suture complexity from infants to about 10 years and no further change for individuals older than 10 years. Conclusions: Quantitative analyses of human sagittal suture using length, length ratio, and DFT indicated that there is a progressive increase in the complexity of sagittal sutural waveform with age, especially in the early ages. These findings agree with the observations from animal experiments that sagittal sutural waveform is the result of intrinsic tissue response to extrinsic forces such as those generated by the temporalis.

Abstract
Blunt abdominal injury with kidney laceration is not unusually seen in high-energy traffic accident. It can present with no symptoms and yet lead to fatal complications. High-grade lacerations of kidney (American Association for the Surgery of Trauma [AAST] grade IV to V) will show up with contrast extravasation and disrupted kidney/pelvicalyceal system morphology in computed tomography (CT). However, it is rare to see kidney dislocation from retroperitoneal space because of the presence of the Gerota's fascia. We present a case of a 16-year-old boy suffering from traffic accident with blunt truncal/abdominal injury. The contrast CT of abdomen revealed that his left kidney was dislocated from the original retroperitoneal space and sagged to the lower retroperitoneal cavity. We performed emergency left nephrectomy. He recovered well and there was no complication noted after the surgical intervention. We also review the literature of kidney laceration regarding diagnosis and treatment. (Hong Kong j.emerg.med. 2016;24:176-179)

Abstract
Thyroid hormone is important for skull bone growth, which primarily occurs at the cranial sutures and synchondroses. Thyroid hormones regulate metabolism and act in all stages of cartilage and bone development and maintenance by interacting with growth hormone and regulating insulin-like growth factor. Aberrant thyroid hormone levels and exposure during development are exogenous factors that may exacerbate susceptibility to craniofacial abnormalities potentially through changes in growth at the synchondroses of the cranial base. To elucidate the direct effect of in utero therapeutic thyroxine exposure on the synchondroses in developing mice, we provided scaled doses of the thyroid replacement drug, levothyroxine, in drinking water to pregnant C57BL6 wild-type dams. The skulls of resulting pups were subjected to micro-computed tomography analysis revealing less bone volume relative to tissue volume in the synchondroses of mouse pups exposed in utero to levothyroxine. Histological assessment of the cranial base area indicated more active synchondroses as measured by metabolic factors including Igf1. The cranial base of the pups exposed to high levels of levothyroxine also contained more collagen fiber matrix and an increase in markers of bone formation. Such changes due to exposure to exogenous thyroid hormone may drive overall morphological changes. Thus, excess thyroid hormone exposure to the fetus during pregnancy may lead to altered craniofacial growth and increased risk of anomalies in offspring.

Abstract
Innate lymphoid cells (ILCs) are master regulators of immune and inflammatory responses, but their own regulatory mechanisms and functional roles of their subtypes (i.e., ILC1s-ILC3s) remain largely unresolved. Interestingly, AMP-activated protein kinase (AMPK), influences inflammatory responses, but its role in modulation of ILCs is not known. Periodontitis is a prevalent disorder with impairment of immune and inflammatory responses contributing importantly to its pathogenesis; however, neither the role of ILCs nor AMPK has been explored in this condition. We tested the hypotheses that (a) periodontitis increases ILCs and expression of relevant cytokines thereby contributing to inflammation and (b) knockdown of AMPK worsens indices of periodontitis in association with further increases in subtypes of ILCs and cytokine expression. The studies utilized wild-type (WT) and AMPK knockout (KO) mice, subjected to ligature-induced periodontitis or sham operation, in association with the use of micro-CT for assessment of bone loss, immunogold electron microscopy to show presence of ILCs in periodontal tissues, flow cytometry for quantitative assessment of subtypes of ILCs and RT-polymerase chain reaction analyses to measure mRNA expression of several relevant cytokines. The results for the first time show (a) presence of each subtype of ILCs in periodontal tissues of sham control and periodontitis animals, (b) that periodontitis is associated with increased frequencies of ILC1s-ILC3s with the effect more marked for ILC2s and differential phenotypic marker expression for ILC3s, (c) that AMPK KO mice display exacerbation of indices of periodontitis in association with further increases in the frequency of subtypes of ILCs with persistence of ILC2s effect, and (d) that periodontitis increased mRNA for interleukin (IL)-33, but not IL-5 or IL-13, in WT mice but expression of these cytokines was markedly increased in AMPK KO mice with periodontitis. Subsequently, we showed that human periodontitis is associated with increases in each ILCs subtype with the effect more marked for ILC2s and that mRNA expressions for IL-33 and IL-5 are markedly greater for sites affected by periodontitis than healthy sites. Collectively, these novel observations indicate a pivotal role for ILCs in pathogenesis of periodontitis and that AMPK is a regulator of their phenotype expression in this condition.

Abstract
Whole-body vibration (WBV) has gained attention as a potential exercise mimetic, but direct comparisons with the metabolic effects of exercise are scarce. To determine whether WBV recapitulates the metabolic and osteogenic effects of physical activity, we exposed male wild-type (WT) and leptin receptor-deficient (db/db) mice to daily treadmill exercise (TE) or WBV for 3 months. Body weights were analyzed and compared with WT and db/db mice that remained sedentary. Glucose and insulin tolerance testing revealed comparable attenuation of hyperglycemia and insulin resistance in db/db mice following TE or WBV. Both interventions reduced body weight in db/db mice and normalized muscle fiber diameter. TE or WBV also attenuated adipocyte hypertrophy in visceral adipose tissue and reduced hepatic lipid content in db/db mice. Although the effects of leptin receptor deficiency on cortical bone structure were not eliminated by either intervention, exercise and WBV increased circulating levels of osteocalcin in db/db mice. In the context of increased serum osteocalcin, the modest effects of TE and WBV on bone geometry, mineralization, and biomechanics may reflect subtle increases in osteoblast activity in multiple areas of the skeleton. Taken together, these observations indicate that WBV recapitulates the effects of exercise on metabolism in type 2 diabetes.

Abstract
As people are getting a better understanding of organism's metabolism and the concept of disease treatment is being continuously updated, parenteral and enteral nutrition become an inter discipline subject that serves for the clinic and involves a number of disciplines. Just in the past five years, related guidelines at home and abroad have been published as much as more than 40. In order to better serve the clinical decision making, this text attempts to give a carding and interpretation from the three aspects of nutrition screening and assessment, the implementing of nutritional intervention and the progress of special nutrition support. It is observed that the standard clinical nutrition diagnosis and treatment process has been formed consensus. But in the practical application, there are still many details need to confirm and further study.

Abstract
BACKGROUND Recruitment of stem cells to sites of tissue injury constitutes an important mechanism aimed at tissue repair and regeneration. However, it is not clear how the diabetic milieu affects the viability of endogenous stem cells. Thus, we tested the hypothesis that diabetes mellitus is associated with increased apoptosis which, in turn, contributes to reduction in stem cells and the manifestation of type 2 diabetic nephropathy. METHODS Sixteen-week-old male obese type 2 diabetic db/db mice, and their appropriate controls, were used for assessment of the status of endothelial progenitor cells (EPCs), mesenchymal stem cells (MSCs), and hematopoetic stem cells (HSCs) in the peripheral blood and renal tissue using specific cell markers. Further, we explored whether diabetic animals display greater apoptosis of stem cell subsets. RESULTS The peripheral blood cells of db/db mice displayed reduction in EPCs (p < 0.05) compared to those of db/m controls. Further, kidney cells prepared from experimental groups also showed reductions in EPCs, MSCs, and HSCs. We also observed increased apoptosis of stem cell subsets in cells prepared from kidneys of db/db than those of db/m mice. CONCLUSIONS The present study shows a similar pattern of decline in stem cell subsets in peripheral blood and kidneys of db/db mice, an effect likely related to increased apoptosis. Collectively, the results suggest that apoptosis of stem cells likely contributes to eventual manifestation of renal failure in diabetes mellitus. Monitoring of blood levels of stem cell subsets could predict failure of their reparative and protective effects and eventual manifestations of diabetic complications.

Abstract
BACKGROUND A lack of agreement on definitions and terminology used for nutrition-related concepts and procedures limits the development of clinical nutrition practice and research. OBJECTIVE This initiative aimed to reach a consensus for terminology for core nutritional concepts and procedures. METHODS The European Society of Clinical Nutrition and Metabolism (ESPEN) appointed a consensus group of clinical scientists to perform a modified Delphi process that encompassed e-mail communication, face-to-face meetings, in-group ballots and an electronic ESPEN membership Delphi round. RESULTS Five key areas related to clinical nutrition were identified: concepts; procedures; organisation; delivery; and products. One core concept of clinical nutrition is malnutrition/undernutrition, which includes disease-related malnutrition (DRM) with (eq. cachexia) and without inflammation, and malnutrition/undernutrition without disease, e.g. hunger-related malnutrition. Over-nutrition (overweight and obesity) is another core concept. Sarcopenia and frailty were agreed to be separate conditions often associated with malnutrition. Examples of nutritional procedures identified include screening for subjects at nutritional risk followed by a complete nutritional assessment. Hospital and care facility catering are the basic organizational forms for providing nutrition. Oral nutritional supplementation is the preferred way of nutrition therapy but if inadequate then other forms of medical nutrition therapy, i.e. enteral tube feeding and parenteral (intravenous) nutrition, becomes the major way of nutrient delivery. CONCLUSION An agreement of basic nutritional terminology to be used in clinical practice, research, and the ESPEN guideline developments has been established. This terminology consensus may help to support future global consensus efforts and updates of classification systems such as the International Classification of Disease (ICD). The continuous growth of knowledge in all areas addressed in this statement will provide the foundation for future revisions.

Abstract
BACKGROUND Craniosynostosis, the premature fusion of one or more of the cranial sutures, is estimated to occur in 1:1800 to 2500 births. Genetic murine models of craniosynostosis exist, but often imperfectly model human patients. Case, cohort, and surveillance studies have identified excess thyroid hormone as an agent that can either cause or exacerbate human cases of craniosynostosis. METHODS Here we investigate the influence of in utero and in vitro exogenous thyroid hormone exposure on a murine model of craniosynostosis, Twist 1 +/-. RESULTS By 15 days post-natal, there was evidence of coronal suture fusion in the Twist 1 +/- model, regardless of exposure. With the exception of craniofacial width, there were no significant effects of exposure; however, the Twist 1 +/- phenotype was significantly different from the wild-type control. Twist 1 +/- cranial suture cells did not respond to thyroxine treatment as measured by proliferation, osteogenic differentiation, and gene expression of osteogenic markers. However, treatment of these cells did result in modulation of thyroid associated gene expression. CONCLUSION Our findings suggest the phenotypic effects of the genetic mutation largely outweighed the effects of thyroxine exposure in the Twist 1 +/- model. These results highlight difficultly in experimentally modeling gene-environment interactions for craniosynostotic phenotypes.

Abstract
Abstract
Introduction:
Autophagy is a catabolic pathway utilized for energy metabolism in nutrient-depleted tumors. Recent studies have reported autophagy to be a survival mechanism found in cancer during stress secondary to cancer progression or treatment. In this study we tested for autophagic activity in malignant melanoma tumors via detection of LC3 antibody following treatment with Cannabidiol (CBD) and cisplatin. The objective of this study was to investigate the effect of treatment with a cannabinoid derivative on autophagic activity in malignant melanoma.
Materials and Methods:
Murine B16F10 melanoma tumors were established subcutaneously in C57BL/6 mice. These mice were then subjected to treatment with local vehicle (PBS) injection (control - group 1, n = 5), systemic Cisplatin injection (group 2; n = 5), and local cannabidiol injection (group 3; n = 5). Tumor cells were subsequently submitted to immunohistochemistry, Brightfield microscopy, and quantitative analysis (Bioquant) for LC3 expression.
Results:
The expression level of LC3 was significantly reduced in groups 2 and 3 when compared to the control group 1. Quantitative measurement of the slides using Bioquant software confirmed our immunohistochemistry and microscopic results.
Conclusions:
If CBD does indeed decrease autophagic activity, it may represent a new and novel therapeutic target in the treatment of malignant melanoma. Additional studies to clarify the specific relationship between CBD and autophagy are in progress and will be reported upon completion.

Abstract
The stromal compartment of adipose tissue harbors multipotent cells known as adipose-derived stem cells (ASCs). These cells can differentiate into various lineages including osteogenic, chrondrogenic, adipogenic, and neurogenic; this cellular fraction may be easily obtained in large quantities through a clinically safe liposuction procedure. Therefore, ASCs offer exceptional opportunities for tissue engineering and regenerative medicine. However, current practices involving ASCs typically use fetal bovine serum (FBS)-based cryopreservation solutions that are associated with risks of immunological reactions and of transmitting infectious diseases and prions. To realize clinical applications of ASCs, serum- and xeno-free defined cryopreservation methods are needed. To this end, an animal product-free chemically defined cryopreservation medium was formulated by adding two antioxidants (reduced glutathione and ascorbic acid 2-phosphate), two polymers (PVA and ficoll), two permeating cryoprotectants (ethylene glycol and dimethylsulfoxide), a disaccharide (trehalose), and a calcium chelator (EGTA) to HEPES-buffered DMEM/F12. To limit the number of experimental groups, the concentration of trehalose, both polymers, and EGTA was fixed while the presence of the permeating CPAs and antioxidants was varied. ASCs suspended either in different versions of the defined medium or in the conventional undefined cryopreservation medium (10% dimethylsulfoxide+10% DMEM/F12+80% serum) were cooled to -70°C at 1°C/min before being plunged into liquid nitrogen. Samples were thawed either in air or in a water bath at 37°C. The presence of antioxidants along with 3.5% concentration of each penetrating cryoprotectant improved the freezing outcome to the level of the undefined cryopreservation medium, but the plating efficiency was still lower than that of unfrozen controls. Subsequently, increasing the concentration of both permeating cryoprotectants to 5% further improved the plating efficiency to the level of unfrozen controls. Moreover, ASCs cryopreserved in this defined medium retained their multipotency and chromosomal normality. These results are of significance for tissue engineering and clinical applications of stem cells.

Abstract
BACKGROUND AND OBJECTIVE Indoleamine 2,3-dioxygenase (IDO) is one of the major pathways for metabolism of tryptophan in a variety of cells, including immune cells. Increasing evidence indicates that IDO is a critical player in establishing the balance between immunity and tolerance and ultimately in the maintenance of homeostasis. By inducing inflammation in gingival tissue, we tested the hypothesis that IDO is a pivotal player in regulating the immune and inflammatory responses of gingiva. MATERIAL AND METHODS We utilized the IDO knockout mouse model in conjunction with lipopolysaccharide (LPS)-induced inflammation. Accordingly, wild-type and IDO knockout mice were injected with LPS or vehicle in the anterior mandibular gingiva, twice over a 2-wk period, which was followed by procurement of gingival tissue for histopathology and preparation of tissue for flow cytometry-based studies. RESULTS Clinical and histological examinations revealed a marked adverse impact of IDO deficiency on gingival inflammation. These observations were consistent with a more marked increase in the number of cells positive for the proinflammatory cytokine interleukin (IL)-17, but no significant change in the number of cells positive for the anti-inflammatory cytokine IL-10, in LPS-treated IDO knockout mice. Consistent with the more marked proinflammatory impact of IDO deficiency, the percentage of regulatory T cells was much reduced in gingival tissue of LPS-treated IDO knockout mice than in gingival tissue of wild-type mice. These proinflammatory changes were accompanied with a prominent increase in apoptotic and necrotic cell death in gingival tissue of IDO knockout mice compared with wild-type mice. CONCLUSION Collectively, our findings support a major role for IDO in the development of gingival inflammation, as an example of an inflammatory condition, and lay the foundation for subsequent studies to explore it as a novel immunotherapy target.

Abstract
It is noteworthy that the incidence of thyroid cancer around the world has increased significantly in recent decades, raising an imperative need to research its pathogenesis, diagnosis and treatment. Up to now, fine needle aspiration biopsy (FNAB) of thyroid has been acknowledged to discriminate benign from malignant thyroid nodules with the highest sensitivity and specificity. However, 10% to 40% thyroid nodules cannot be discriminated by FNAB. Therefore, it is vitally important to look for highly-correlated tumor makers in molecule level. BRAF mutation is a focus in thyroid cancer research, and some studies showed that this mutation is essential to the onset and development of thyroid cancer, especially papillary thyroid cancer. Joint detection of BRAF mutation could improve diagnostic sensitivity of thyroid cancer, which is crucial for thyroid cancer diagnosis and classification. As for treatment, the discovery of target gene enabled molecule therapy for thyroid cancer, raising hopes for patients with thyroid cancer that refractory to conventional treatments. Currently, many molecule therapeutics relating to BRAF has already undergone clinical trials. It is believed that further research on BRAF-thyroid cancer relationship could create a new field for diagnosis and treatment of thyroid cancer, and set a mode for discovering others molecule markers.

Abstract
Background We recently showed that an imbalance between the pro-inflammatory
cytokine, interleukin (IL)-17, and the developmental endothelial locus-1 (Del-1)
likely contributes to inflammation and salivary gland abnormalities in Sjögren’s
syndrome (SS). The glucocorticoid-induced leucine zipper (GILZ) protein is a
pivotal player in mediating the anti-inflammatory effects of glucocorticoids.
However, its status and role in salivary gland inflammation and dysfunction in SS
are not established. Thus, we tested the hypothesis that SS is associated with
reduced GILZ expression, thereby contributing to Del-1/Il-17 imbalance and
inflammation in salivary glands. Methods We utilized the nonobese diabetic (NOD) mice, a model of SS-like
disease as well as lower-lip biopsy samples of subjects without or with a
diagnosis of SS in association with immunostaining studies. These studies were
complemented with in vitro and flow-cytometry studies whereby interleukin
(IL)-23-treated salivary gland cells were co-cultured with GILZ-expressing cells
or control cells; IL-23 is known to increase generation of IL-17. Results Salivary glands of NOD mice displayed marked leukocyte infiltration
and reduced GILZ expression in association with increased IL-17 but decreased
Del-1 expression. A similar pattern was observed for lower-lip biopsy samples of
SS than non-SS subjects. Further, IL-23-treated salivary gland cells displayed
marked increase in IL-17 but reduced Del-1 positive cells which were reversed with
co-culturing with GILZ-expressing cells but not control cells. Collectively, the
results are suggestive of dysregulation of GILZ playing a role in inflammation and
associated Del-1/Il-17 imbalance in SS. Conclusions Complementing our demonstration of Del-1/IL-17 imbalance in salivary
glands in SS, the present study has established the relevance and significance of
GILZ as a novel predictive and prognostic molecular fingerprint for SS. Thus,
assessment of minor salivary gland GILZ expression, in conjunction with
Del-1/IL-17 imbalance, could potentially offer a more sensitive approach to help
with diagnosis of SS, at early stage of the disease, than that based on leukocyte
infiltration. Future studies should establish whether treatment with GILZ
ameliorates signs and symptoms of salivary malfunction of SS for which effective
treatment options remain elusive.

Abstract
Abstract
Introduction: Innate lymphoid cells (ILCs), have emerged as novel important immune effector cells, playing a critical role also in tumor immune-surveillance. Recently, it was shown that the number of ILCs in patients with different types of cancer is significantly reduced after chemotherapy/radiotherapy as compared to healthy donors. However, so far, no data on ILC frequency, subset distribution and function in patients with melanoma are available. Therefore, we analyzed the frequency, subset distribution and function of ILCs in a murine model of melanoma with/without treatment, a parameter that is of paramount importance to understand the role of ILCs during melanoma and to assess the impact of current treatments on this type of cancer.
Methods: C57/BL6 mice were injected with B16F10 murine melanoma cell line (1 x 106 cells/mouse, subcutaneous). Tumor growth monitored. Once tumors reached 12mm in size, the mice were sacrificed and tumor cells subjected to flow-cytometry and cell culture to identify the ILC subclasses in the tumor.
Results: Our findings establish, for the first time in melanoma at diagnosis, base-line reference values for ILC frequency and function, as well as the ILC subtype distribution.
Conclusion: Our studies extend previously published work on changes in innate lymphoid cells. Our findings will help better understanding of tumor microenvironment and its interaction with immune system. These values indicate the potential of ILCs as crucial players in the treatment of cancer, specifically melanoma.

Abstract
There is a worsening epidemic of obesity and diabetes in the world. Life style interventions including dietary changes and increase in exercise can improve glucose metabolism and health in general. However, standard exercise programs are strenuous, time-consuming, and thus have low long-term compliance issues. We tested the feasibility of using high frequency, low amplitude whole body vibration (WBV) therapy to improve glucose metabolism in young type 2 diabetic (T2DM) mice. We also aimed to investigate the postulated anti-inflammatory and cytoprotective properties of WBV. Male db/db and db/m mice were exposed to high frequency, low-amplitude WBV. Outcome parameters comprised of body weight, hemoglobin A1c (HbA1c) level, as well as interleukin (IL)-17 (a marker of helper T cells), forkhead box P3 (Foxp3; a marker of regulatory T cells), and gammaH2AX (an index of DNA injury) expression. Furthermore, a 24 h metabolic cage study was carried out immediately after the WBV protocol and fluid intake, urine excretion and urine osmolality were determined. WBV did not affect body weight but improved HbA1c levels in db/db mice. Vibrated db/db mice demonstrated less fluid intake and urine excretion but better urinary concentrating ability than their non-vibrated controls. Pro-inflammatory changes were significantly reduced, as indicated by reduced IL-17 but increased Foxp3 expression. WBV reduced gammaH2AX in db/db mice suggestive of cytoprotective effect. However, WBV was largely without significant effects on assessed parameters in db/m mice. Collectively, our findings suggest that daily, short duration WBV may improve glycemic control, polydipsia, polyuria, and urine osmolality in T2DM in association with reduced inflammation. Thus, WBV may be a viable adjunctive treatment strategy in T2DM.

Abstract
Purpose The inhibition of serum glucocorticoid-regulated kinase-1 (SGK-1) has been found to decrease growth of colon and prostate cancer cells. The purpose of this study is to evaluate the therapeutic effect of SGK-1 inhibition in head and neck squamous cell carcinoma (SCC). Experimental Design Human head and neck tumors (HTB41/43) were established in athymic mice. Growth rates between mice treated with vehicle (PBS) injection (group 1, n = 5), SGK-1 Inhibitor GSK 650394 (group 2, n = 6), systemic cisplatin (group 3, n = 6), and a combination of SGK-1 Inhibitor and cisplatin (group 4, n = 6) were compared using repeated measures one-way ANOVA with Newman-Keuls Multiple Comparison Test. Tumor cells were subsequently submitted to further analyses. Results At the end of the experiment mean tumor sizes were 122.33+/−105.86, 76.73+/−36.09, 94.52+/−75.92, and 25.76+/−14.89 mm2 (mean +/− SD) for groups 1 to 4. Groups 2 and 3 showed decreased tumor growth compared to controls (p<0.001). Group 4 displayed even greater growth suppression (p<0.0001). Importantly, group 4 fared better than group 3 (p<0.001). CD44 expression was reduced in group 2 (p<0.05), and to an even greater extent in groups 3 and 4 (p<0.0025). A trend towards reduction of HER 2 expression was noted in group 4. Conclusions SGK-1 inhibition suppresses tumor growth, and in combination with systemic cisplatin exceeds the effect of cisplatin alone. Decreased expression of CD44 and HER 2 implies depletion of tumor stem cells, and less tumorigenicity. SGK-1 inhibition represents a potential modality of local control for palliation in advanced cases.

Abstract
Objectives: Investigate if facial fractures predispose patients to developing Parkinson’s disease. Facial trauma ranges from lacerations to complex facial fractures. These fractures can result from sports, motor vehicle collisions, or assaults. The long-term neurologic effects of facial fractures have not been studied. Significant force is required to break midface buttresses or the mandible. Such force is transmitted toward the cranial vault contents. The location of the basal ganglia along the skull base predispose this area to higher strain. Chronic traumatic encephalopathy (CTE) shows similar neurologic damage related to repeated head injuries, as seen in the NFL and boxing. Methods: A total of 146 Parkinson’s patients were recruited from the neurology clinic. They were given a voluntary survey. This survey consisted of demographic questions: sex, age, age of diagnosis, involvement in sports, and history of facial fractures. The incidences of facial fracture ICD9 820.0 were analyzed with Wolfram Alpha and then chi-square. Results: Twenty-two of 146 (15%) had a positive history of facial fractures. Of the 22, 9 (6%) experienced multiple fractures. Twenty-six of 146 (17.8%) patients were involved in contact sports, with 7 out of 26 patients having fractures and participating in sports. Utilizing Wolfram Alpha, the incidence of ICD9 820.0 was calculated to be 1 out of 4100 (0.024%) in the US population. A chi-square test comparing our results showed a P value of .023 Conclusions: Based on these statistically significant results, patients who experience facial fractures show an increased predilection for developing Parkinson’s disease.

Abstract
Craniosynostosis (CS) is a relatively common birth defect resulting from the premature fusion of one or more cranial sutures. Human genetic studies have identified several genes in association with CS. One such gene that has been implicated in both syndromic (Saethre-Chotzen syndrome) and nonsyndromic forms of CS in humans is TWIST1. In this study, a heterozygous Twist1 knock out (Twist1(+/-) ) mouse model was used to study the craniofacial shape changes associated with the partial loss of function. A geometric morphometric approach was used to analyze landmark data derived from microcomputed tomography scans to compare craniofacial shape between 17 Twist1(+/-) mice and 26 of their Twist1(+/+) (wild type) littermate controls at 15 days of age. The results show that despite the purported wide variation in synostotic severity, Twist1(+/-) mice have a consistent pattern of craniofacial dysmorphology affecting all major regions of the skull. Similar to Saethre-Chotzen, the calvarium is acrocephalic and wide with an overall brachycephalic shape. Mutant mice also exhibited a shortened cranial base and a wider and shorted face, consistent with coronal CS associated phenotypes. The results suggest that these differences are at least partially the direct result of the Twist1 haploinsufficiency on the developing craniofacial skeleton. This study provides a quantitative phenotype complement to the developmental and molecular genetic research previously done on Twist1. These results can be used to generate further hypotheses about the effect of Twist1 and premature suture fusion on the entire craniofacial skeleton.

Abstract
We used a newly developed electrochemical method, real-time resistance measurement, based on loop-mediated isothermal amplification (LAMP), with real-time resistance monitoring and derivative analysis. DNA extracted from specimens was amplified through LAMP reaction. The 2 products of LAMP, DNA and pyrophosphate, both are negative ions; they combine with positive dye (crystal violet) and positive ions (Mg(2+)), which leads to an increase in the resistivity of the reaction liquid. The changes of resistivity were measured in real-time with a specially designed resistance electrode, to detect Clostridium difficile DNA. We found that electrochemical detection of C. difficile could be completed in 0.5-1 h, with a detection limit of 10(2) CFU/mL, with high accuracy (95.0%), sensitivity (91.1%), and specificity (97.3%) compared to PCR methods. C. difficile is commonly associated with antibiotic-induced diarrhea. Due to the difficulty in performing anaerobic culture and cytotoxicity neutralization assays, a simple, rapid, sensitive, and accurate method is preferred. We conclude that real-time resistance measurement is a rapid, sensitive, and stable method for the diagnosis of C. difficile infection that could be applied to gene chips and pocket instruments.

Abstract
The incidence of craniosynostosis is one in every 1,800–2500 births. The gene-environment model proposes that if a genetic predisposition is coupled with environmental exposures, the effects can be multiplicative resulting in severely abnormal phenotypes. At present, very little is known about the role of gene-environment interactions in modulating craniosynostosis phenotypes, but prior evidence suggests a role for endocrine factors. Here we provide a report of the effects of thyroid hormone exposure on murine calvaria cells. Murine derived calvaria cells were exposed to critical doses of pharmaceutical thyroxine and analyzed after 3 and 7 days of treatment. Endpoint assays were designed to determine the effects of the hormone exposure on markers of osteogenesis and included, proliferation assay, quantitative ALP activity assay, targeted qPCR for mRNA expression of Runx2, Alp, Ocn, and Twist1, genechip array for 28,853 targets, and targeted osteogenic microarray with qPCR confirmations. Exposure to thyroxine stimulated the cells to express ALP in a dose dependent manner. There were no patterns of difference observed for proliferation. Targeted RNA expression data confirmed expression increases for Alp and Ocn at 7 days in culture. The genechip array suggests substantive expression differences for 46 gene targets and the targeted osteogenesis microarray indicated 23 targets with substantive differences. 11 gene targets were chosen for qPCR confirmation because of their known association with bone or craniosynostosis (Col2a1, Dmp1, Fgf1, 2, Igf1, Mmp9, Phex, Tnf, Htra1, Por, and Dcn). We confirmed substantive increases in mRNA for Phex, FGF1, 2, Tnf, Dmp1, Htra1, Por, Igf1 and Mmp9, and substantive decreases for Dcn. It appears thyroid hormone may exert its effects through increasing osteogenesis. Targets isolated suggest a possible interaction for those gene products associated with calvarial suture growth and homeostasis as well as craniosynostosis.

Abstract
SYNOPSIS Major liver resection prevents intrahepatic tumor recurrence in T2 hepatocellular carcinoma patients with microvascular invasion or daughter nodules. BACKGROUND AND OBJECTIVES There is no consensus on whether major or minor hepatectomy is better for hepatocellular carcinoma (HCC) patients. We investigated the outcomes of liver resection type in resectable HCC patients. METHODS Two hundred sixty-three HCC patients with Child-Pugh class A liver function who underwent curative hepatectomy were enrolled. Among them, 186 patients had pathologic stage T1 HCC and 77 had stage T2 HCC. Patients were also classed according to the type of resection (major or minor). Clinicopathologic characteristics and outcomes were compared. RESULTS Patients with T1 HCC who underwent major resection had a higher rate of blood transfusion than those who underwent minor resection (P < 0.001). The disease-free survival rate of T2 patients who underwent major resection was better than that of patients who underwent minor resection (P = 0.004). The overall survival rates of T1 and T2 HCC patients did not differ significantly between those with major or minor resection. CONCLUSIONS Major liver resection is recommended for T2 HCC patients with adequate remnant liver function because it results in a better disease-free survival rate than does minor resection in these patients. Minor liver resection is suggested for T1 HCC patients, except for those with a tumor sitting close to vessels, because it is associated with a low incidence of blood transfusion and a good survival rate.

Abstract
AIMS/HYPOTHESIS Haem oxygenase 1 (HO-1) has strong anti-apoptotic, anti-inflammatory and antioxidative effects that help protect cells against various forms of immune attack. We investigated whether transgenic expression of Ho-1 (also known as Hmox1) in pancreatic beta cells would protect NOD mice from autoimmune damage and prolong graft survival following islet transplantation. METHODS To evaluate the protective effect of beta cell-specific HO-1 in autoimmune diabetes, we used an insulin promoter-driven murine Ho-1 construct (pIns-mHo-1) to generate a transgenic NOD mouse. Transgene expression, insulitis and the incidence of diabetes in mice were characterised. Lymphocyte composition, the development of T helper (Th)1, Th2 and T regulatory (Treg) cells, T cell proliferation and lymphocyte-mediated disease transfer were analysed. The potential effects of transgenic islets and islet transplantation on apoptosis, inflammation and the generation of reactive oxygen species (ROS) and reactive nitrogen species (RNS) were evaluated. RESULTS Transgenic mice showed less severe insulitis and a lower incidence of diabetes than non-transgenic control littermates. Lymphocyte composition and functions were not affected. Islets from transgenic mice expressed lower levels of proinflammatory cytokines/chemokines, proapoptotic gene expression and amounts of ROS/RNS, and were more resistant to TNF-α- and IFN-γ-induced apoptosis. Islet grafts from transgenic mice also survived longer in diabetic recipients than control islets. CONCLUSIONS/INTERPRETATION Transgenic overexpression of Ho-1 in beta cells protected NOD mice from diabetes and delayed the autoimmune destruction of islet grafts, providing valuable insight into the development of better strategies for clinical islet transplantation in patients with type 1 diabetes.

Abstract
OBJECTIVES Although phytobezoars are a rare cause of gastrointestinal obstruction, they are most commonly found in patients with previous gastric surgery. It is well known that predisposing factors of phytobezoar formation are ingestion of fruits containing soluble tannin, presence of dilute hydrochloric acid in the stomach, and gastric stasis or delayed emptying. We investigated whether intake of acid-suppressing drugs that neutralize gastric acidity or inhibit gastric acid secretion to constitute a hypo-acidic condition, increases the risk of phytobezoar formation. MATERIALS AND METHODS Between September 1992 and October 2008, 32 patients (24 male and 8 female) with gastrointestinal phytobezoars were diagnosed either surgically or endoscopically at the Tri-Service General Hospital, Taipei, Republic of China. The data were collected from hospital records and analyzed retrospectively. RESULTS Eighteen (56.25%) of all patients had previous gastric surgery and 6 (42.9%) of the 14 patients who had not undergone surgery had diabetes mellitus. The majority of admissions were during winter and spring (between October and March) (P < 0.01) and none of the patients had taken acid-suppressing drugs during the 6 months before detection of gastrointestinal phytobezoars. CONCLUSIONS In our study, intake of acid-suppressing drugs did not increase the risk of phytobezoar formation in patients with normal gastric motility. Moreover, we believe that the major factor in phytobezoar formation is gastric stasis or delayed emptying, which sufficiently prolongs the retention period of materials in the stomach, while dilute hydrochloric acid is a minor factor.
