Human dental pulp stem/stromal cells in clinical practice

Dental pulp stem/stromal cells(DPSCs)are fibroblast-like,neural crest-derived,and multipotent cells that can differentiate into several lineages.They are relatively easy to isolate from healthy and inflamed pulps,with little ethical concerns and can be successfully cryopreserved and thawed.The therapeutic effects of DPSCs derived from animal or human sources have been extensively studied through in-vitro and in-vivo animal experiments and the findings indicated that DPSCs are effective not only for dental diseases but also for systemic diseases.Understanding that translational research is a critical step through which the fundamental scientific discoveries could be translated into applicable diagnostics and therapeutics that directly benefit humans,several clinical studies were carried out to generate evidence for the efficacy and safety of autogenous or allogeneic human DPSCs(hDPSCs)as a treatment modality for use in cell-based therapy,regenerative medicine/dentistry and tissue engineering.In clinical medicine,hDPSCs were effective for treating acute ischemic stroke and human exfoliated deciduous teeth-conditioned medium(SHED-CM)repaired vascular damage of the corpus cavernous,which is the main cause of erectile dysfunction.Whereas in clinical dentistry,autologous SHED was able to rege-nerate necrotic dental pulp after implantation into injured teeth,and micrografts enriched with autologous hDPSCs and collagen sponge were considered a treatment option for human intrabony defects.In contrast,hDPSCs did not add a significant regenerative effect when they were used for the treatment of post-extraction sockets.Large-scale clinical studies across diverse populations are still lacking to provide robust evidence on the safety and efficacy of hDPSCs as a new treatment option for various human diseases including dental-related problems.

Studies on Human Dietary Requirements and Safe Range of Dietary Intakes of Selenium in China and Their Application in the Prevention of Related Endemic Diseases

The human dietary selenium requirement in China has been estimated by various methods. The minimum dietary selenium requircment for the prevention of Keshan disease (KD) was found to be around 17 μg/d. On the other hand, an intake of 40 μg/d is required to maintain the plasma glutathione peroxidase (GPx) activity at plateau. Hence 40 μg/d is considered as the adequate dietary selenium requirement. Studies conducted in a chronic selenosis area indicate thai the toxic dietary selenlum inlake (adverse effect level), which would maintain the characteristic fingernail changes, was approximately 1600 μg/d. The mean value of dietary selenium intakes, which enabled the five patients to recover from fingernail lesions, was found to be 819 ±126μg/d. At a 95% confidence limit, the lower limit is around 600μg/d. Therefore, 600 and 400μg/d were suggested as the individual daily maximum safe selenium intake and the safe dietary selenium intake, respectively,The results were used in the prevention of Se-related endemic KD and Kashin-Beck disease (KBD)

Letter from Li Peng Chairman of the Standing Committee of the National People's Congress, To China Society for Human Rights Studies

China Society for Human Rights Studies, I would like to extend my warm greetings to the launch of your Human Rights magazine. Enjoying human rights fully is a lofty goal long pursued after by human race. Over the years when they carried out revolution, construction and reforms, the Chinese people have struggled indomitably and strived incessantly to achieve this goal. Progress made in this regard has caught worldwide attention. When struggling for, safeguarding, promoting and developing human rights, the Chinese people have always combined the universality prin-

THE STUDIES ON MONOCLONAL ANTIBODY SZ-39 AGAINST HUMAN GLIOMA CELLS

A hybridoma cell line SZ-39 secreting monoclonal antibody against the human glioma cell has been established by a fusion between NS-1 myeloma cells and spleen cells from mice immunized with human glioma cell lines. Monoclonal antibody (McAb) SZ-39 was analyzed by ELISA, quantitative absorption, indirect immunofluorescence and ABC immunohistology. McAb SZ-39 strongly bound to 9/10 glioma cell lines, 17/20 glioma tissues, weakly bound to one liver cancer cell line and 1/2 lung cancer line, but they did not band with other tested human cancer linse. NcAb SZ-39 have no cross-reaction with lymphocyte, ABC red blood cells, white blood cells, blood platelet, normal bone marrow cells, fibroblast cells and 12 normal human tissues.The result indicated the antigen recognized by McAb SZ-39 may be a glioma-associated antigen <GAA). This GAA was analyzed by means of Western blotting. It was a MW 180 Kd glycopro-tein. The 131I-McAb SZ-39 specifically localized in human glioma xenografted in nude mice that indicate it may be useful in radioimmunoimaging and as a target for immunotherapy on human glioma.

Role of gut microbiota in ischemic stroke:A narrative review of human and animal studies

The high incidence,mortality,and disability associated with ischemic stroke pose a significant threat to human health.The intestinal microbiota significantly influences the onset,progression,and prognosis of ischemic stroke.Gut flora plays a pivotal role in brain-gut interactions.The reflection of changes in the gut and brain caused by gut microbes faciltates the investigation of early warning biomarkers and potential therapeutic targets for ischemic stroke.In this narrative review of the relationship between gut microbiota and ischemic stroke,we primarily discuss three topics,grounded in real-world human and animal studies.First,we examined the relationship between ischemic stroke and intestinal microbiota and its metabolites,delineate the overall characteristics of intestinal microbiota dysregulation in ischemic stroke,and assess the potential clinical value,prevailing research controversies,and unique phenomena of intestinal microbiota metabolites such as trimethylamine N-oxide and short-chain fatty acids in ischemic stroke.Second,we explored the potential communication pathways between intestinal flora and ischemic stroke based on the brain-gut axis,encompassing metabolic pathways,immune pathways,and neural pathways.Finally,we encapsulated the factors influencing the severity of ischemic stroke via intestinal flora,the pharmacological and nonpharmacological interventions that modulate intestinal flora in treating ischemic stroke,and the current research landscape of intestinal flora in the context of ischemic stroke sequelae.

Therapeutic Approach for Hair Growth and Regeneration Using Bioactive Formulation Containing Mesenchymal Stromal Cell-Derived Conditioned Medium

Background and Aims: Androgenetic alopecia (AGA) is a common form of hair loss in both men and women. Despite its high prevalence and associated patient morbidity, the approved therapeutic options are limited to finasteride and minoxidil. The present study is aimed at assessing the efficacy of hair serum formulation, Trichosera®containing Bone marrow-derived mesenchymal stromal cells conditioned media as an active ingredient, for hair fall control and hair regrowth in healthy Indian human volunteers. Methods: The product was made using a 20% concentration of 10X Conditioned Media along with excipients. The final product was tested for physicochemical parameters, biomarkers, total protein content and microbial limits as per our in-house specifications. Results: The primary irritation patch test showed that the product is non-irritant and dermatologically safe. A clinical study on 40 subjects was conducted to evaluate the effectiveness of the bioactive formulation in hair fall control and hair regrowth in healthy volunteers. Phototrichogram measurement showed hair density and hair growth rate increased significantly by 11.54% and 18.66% at week 24. Hair tensile strength also increased significantly by 41.10% at 12 weeks follow-up. Hair pull test, to see a reduction in pulled hair and comb’s test to show a decrease in hair fall significantly improved from week 4 onwards. There were no significant adverse events in response to the product application. Conclusion: It is concluded that the hair serum product is completely safe on direct application to the scalp and showed significant improvement in the hair growth rate, hair density, scalp condition and reduction in hair fall. .

Prolonged intestinal mucosal acidosis is associated with multiple organ failure in human acute pancreatitis: Gastric tonometry revisited

AIM： To evaluate whether multiple determinations of intramucosal pH （pHi） in acute pancreatitis （AP） patients could provide additional information of the disease severity during early hospitalization. METHODS： Twenty-one patients suffering from acute pancreatitis were monitored by gastric tonometry in the first 72 h after hospital admission. RESULTS： In the survivor group （n = 15） the initially low phi values returned to normal level （pHi ≥ 7.32） within 48 h （median pHi： d 1： 7.21; d 2： 7.32; d 3： 7.33）. In contrast, pHi values in the non-survivor group n = 6） were persistently either below or in the low normal range （median pHi 7.12; 7.12; 7.07 respectively）, but pHi differences between the two groups reached significance only after 24 h （P 〈 0.01）. Mucosal acidosis detected at any time during the monitored period was associated with the emergence of single or multiple organ dysfunction （P 〈 0.01）. CONCLUSION： Prolonged gastric mucosal acidosis was associated with remote organ dysfunction and failure in Acute Pancreatitis, however, correlation with the fatal outcome became significant only 24 h after admission. Due to its non-invasive nature gastric tonometry may supplement the pro-inflammatory markers to achieve a multi-faceted monitoring of the disease.

Noni juice is not hepatotoxic

Noni juice （Morinda citrifolia） has been approved for use as a safe food within the European Union, following a review of safety. Since approval, three cases of acute hepatitis in Austrian noni juice consumers have been published, where a causal link is suggested between the liver dysfunction and ingestion of anthraquinones from the plant. Measurements of liver function in a human clinical safety study of TAHITIAN NONI Juice, as well as subacute and subchronic animal toxicity tests revealed no evidence of adverse liver effects at doses many times higher than those reported in the case studies. Additionally, M. citrifolia anthraquinones occur in the fruit in quantities too small to be of any toxicological significance. Further, these do not have chemical structures capable of being reduced to reactive anthrone radicals, which were implicated in previous cases of herbal hepototoxicity. The available data reveals no evidence of liver toxicity.
