ABSTRACT
X-linked hypophosphatemia (XLH) represents the most common form of familial hypophosphatemia. Although significant advances have been made in the treatment of bone pathology, patients undergoing therapy continue to experience significantly decreased oral health-related quality of life. The following study addresses this persistent oral disease by further investigating the effect of DMP1 expression on the differentiation of XLH dental pulp cells. Dental pulp cells were isolated from the third molars of XLH and healthy controls and stable transduction of full-length human DMP1 were achieved. RNA sequencing was performed to evaluate the genetic changes following the induction of odontogenic differentiation. RNAseq data shows the upregulation of inhibitors of the canonical Wnt pathway in XLH cells, while constitutive expression of full-length DMP1 in XLH cells reversed this effect during odontogenic differentiation. These results imply that inhibition of the canonical Wnt pathway may contribute to the pathophysiology of XLH and suggest a new therapeutic strategy for the management of oral disease.

X-linked hypophosphatemia (XLH) is a rare disease of elevated fibroblast growth factor 23 (FGF23) production that leads to hypophosphatemia and impaired mineralization of bone and teeth. The clinical manifestations of XLH include a high prevalence of dental abscesses and periodontal disease, likely driven by poorly formed structures of the dentoalveolar complex, including the alveolar bone, cementum, dentin, and periodontal ligament. Our previous studies have demonstrated that sclerostin antibody (Scl-Ab) treatment improves phosphate homeostasis, and increases long bone mass, strength, and mineralization in the Hyp mouse model of XLH. In the current study, we investigated whether Scl-Ab impacts the dentoalveolar structures of Hyp mice. Male and female wild-type and Hyp littermates were injected with 25 mg·kg-1 of vehicle or Scl-Ab twice weekly beginning at 12 weeks of age and euthanized at 20 weeks of age. Scl-Ab increased alveolar bone mass in both male and female mice and alveolar tissue mineral density in the male mice. The positive effects of Scl-Ab were consistent with an increase in the fraction of active (nonphosphorylated) β-catenin, dentin matrix protein 1 (DMP1) and osteopontin stained alveolar osteocytes. Scl-Ab had no effect on the mass and mineralization of dentin, enamel, acellular or cellular cementum. There was a nonsignificant trend toward increased periodontal ligament (PDL) attachment fraction within the Hyp mice. Additional PDL fiber structural parameters were not affected by Scl-Ab. The current study demonstrates that Scl-Ab can improve alveolar bone in adult Hyp mice.

Vascular dementia(VD)is caused by cerebrovascular diseases,either hemorrhage or ischemic damage in the brain,with ischemia being the most common.In recent years,increasing efforts have been made to study the etiology,pathogenesis,and prevention of VD.The establishment of appropriate animal models to study the mechanism of VD and explore the efficacy of VD treatments has become an important issue in this research field.On the basis of conventional method,such as bilateral occlusion of common carotid arteries(2VO)and four-vessel occlusion,researchers have modified these method to improve stability with better reflection of the clinical manifestations of VD.This review summarizes these modified method and discusses possible cellular and molecular mechanisms and their advantages and disadvantages.
ABSTRACT
Objective:To explore the predictive value of peripheral blood CD34-positive cell count for the stem cell mobilization effect of plerixafor in patients with multiple myeloma (MM).Methods:The clinical data of 12 MM patients who used plerixafor for stem cell mobilization in the First Affiliated Hospital of Guangxi Medical University from December 2019 to February 2021 were retrospectively analyzed. The changes of peripheral blood CD34-positive cell count and the collection status of stem cell in all patients before and after the mobilization of plerixafor were analyzed.Results:Twelve patients were included in this study. These patients were in international staging system (ISS) stage Ⅱ-Ⅲ, and the induction therapy was mainly VRD regimen. The CD34-positive cell count was increased after the use of plerixafor in all patients no matter which mobilization strategies were used before plerixafor. The CD34-positive cell count was 3.63/μl (0.72-13.53/μl) and 32.11/μl (8.52-53.68/μl) before and after the use of plerixafor, and the difference was statistically significant ( Z = -0.40, P<0.001); the median increasing time was 11.50 times (1.61-23.71 times). The mobilization failure occurred in 1 patient. The CD34-positive cell count in his blood was less than 1/μl before the use of plerixafor; though increased 11.83 times after the use of plerixafor, the CD34-positive cell count was still less than 10/μl. Pearson analysis showed that among the patients with CD34-positive cell count less than 4/μl before the use of plerixafor, there was a positive correlation in peripheral blood CD34-positive cell count before and after the use of plerixafor ( r = 0.80, P = 0.032). Conclusions:The peripheral blood CD34-positive cell count has a certain predictive value for the stem cell mobilization effect of plerixafor in MM patients.
ABSTRACT
OBJECTIVE@#To observe the therapeutic effect of different doses of dihydroartemisinin (DHA) on atopic dermatitis (AD) in mice and explore the mechanism.@*METHODS@#Forty-two C57BL/6 mice were randomly divided into 7 groups (@*RESULTS@#Treatment with 25, 75, and 125 mg/kg DHA and dexamethasone all alleviated AD symptoms of mice, reduced the severity scores of skin lesions, and ameliorated pathological changes of the skin tissue. DHA at 125 mg/kg produced the most obvious therapeutic effect and significantly alleviated mast cell infiltration in the lesions as compared with the other treatment groups (@*CONCLUSIONS@#DHA is effective for the treatment of AD in mice with an optimal dose of 125 mg/kg. The therapeutic effect of DHA is achieved probably through regulation of local immunity by inhibiting mast cell infiltration in the lesions.

<p><b>OBJECTIVE</b>To explore the diagnosis, treatment and long-term outcome of late acute rejection (LAR) following adult orthotropic liver transplantation (OLT).</p><p><b>METHODS</b>A total of 398 consecutive adult patients who underwent OLT in Organ Transplant Center, the First Affiliated Hospital, Sun Yat-sen University between January 2007 and December 2012 were reviewed retrospectively. There were 48 patients (12. 1%) developed to LAR, including 43 male patients and 5 female patients, with an average age of (52 ± 13) years(18 - 70 years). The mean body mass index was (22.1 ± 4. 5) kg/m2 (15. 4 - 30. 4 kg/m2). The indications of the liver transplantation recipients included 16 cases of end-staged liver cirrhosis after hepatitis B or C(33. 3%), 14 cases with severe hepatitis (29. 2%), 9 cases of primary liver cancer(18. 5%), 5 cases of alcoholic liver cirrhosis (10. 4%), 1 case with autoimmune liver disease (2. 1%) , the other 3 cases (6. 3%). They were followed up by outpatient service, telephone and other means. Survival curves were generated with the Kaplan-Meier method and Cox proportional hazards modeling was used for predictors of mortality. Statistically significant variables found by single factor regression analysis were put into the Cox proportional hazards regression model of multivariate analysis.</p><p><b>RESULTS</b>The time-to-event was 23. 6 months after OLT which were more common in the first year to the third year post-transplant (26/48,52. 4%). Thirty-five cases were assessed as mild, 11 cases were assessed as moderate, and 2 cases were assessed as severe ,based on the Banff schema. After adjustment to the immunosuppressive regimen, the overall recovery rate reached to 81. 3%. The rate of steroid-resistant acute rejection was 11. 8% (4/34). Inadequate immunosuppression and steroid pulsation were two independent risk factors affecting the prognosis of LAR (P = 0. 008, P = 0. 003, respectively).</p><p><b>CONCLUSIONS</b>LAR is an uncommon complication after OLT. Inadequate immunosuppression and steroid pulsation are the major risk factors for prognosis of LAR. Improving patient compliance and strengthening blood concentration surveillance can increase the patient survival.</p>

ABSTRACT
Objective To investigate the role of precursor of brain derived neurotrophic factor (proBDNF) in the improvement of motor function of rats subjected to cord transection. Methods Spinal cord transection was performed at T10 level. The rats were divided into sham operation group and artificial cerebrospinal fluid group. Then, the rats were subjected to proBDNF antibody treatment. The efficiency of proBDNF block was also determined by immunohistochemistry. BBB scale scores were used to e-valuate the effect of ProBDNF block on the motor function of the rats with spinal cord transection. Results Compared with control rats, proBDNF treatment showed a marked down-regulation of proBDNF protein in the spinal cord and could significantly improve the motor function. BBB scores in proBDNF block group was higher than those in artificial cerebrospinal fluid group. Conclusion The proBDNF block is available to the recovery of the motor function in hindlimbs in cord transected rats, suggesting that proBDNF could be as a member of candidate molecules for SCI therapy in the future.

Objective To investigate the effects of human S100A6 on β-catenin in human osteosarcoma cell lines MG63 and U2OS. Methods Cell lines MG63 and U2OS were infected by recombinant adenoviruses carrying human S100A6 and its siRNA gene, AdS100A6 and AdSiS100A6 respectively, to up-regulate and down-regulate the ex-pression of S100A6. Then RT-PCR, Western blot and immunocytochemistry were used to detect mRNA and protein (level and/or distribution) of β-catenin. Results In both cell lines, with up-regulated S100A6, expression of β-catenin mRNA and protein increased(P <0. 05) and β-catenin protein increase was more obvious in nuclear than in cytoplasma; while down-regulating S100A6, both the mRNA and protein level of β-catenin decreased (P<0. 05) ; β-catenin protein decrease was more obvious in nuclear than in cytoplasma, too. Conclusion In-creasing Wnt/β-catenin signaling activity may be a mechanism that S100A6 involves in tumor development.
