ABSTRACT

Diabetes mellitus and pancreatic ductal adenocarcinoma are two common diseases worldwidely which are both derived from different components of pancreas. The pancreatic and duodenal homeobox-1 (PDX1) is an essential transcription factor for the early development of pancreas that is required for the differentiation of all pancreatic cell lineages. Current evidence suggests an important role of PDX1 in both the origin and progression of pancreatic diseases. In this review, we discussed recent studies of PDX1 in diabetes mellitus and pancreatic cancer, and the therapeutic strategies derived from this transcription factor.

ABSTRACT

INTRODUCTION@#Isolated oval window atresia (OWA) is a rare cause of congenital conductive middle ear deafness and may be overlooked owing to the normal appearance of the external ear. This anomaly has been previously described, although the published numbers with both imaging and surgical findings are few. Our aim is to correlate the imaging features of OWA with intraoperative findings.@*MATERIALS AND METHODS@#This is a single-centre retrospective evaluation of patients who were diagnosed with OWA and who received surgery from January 1999 to July 2006. No new case was diagnosed after 2006 to the time of preparation of this manuscript. High resolution computed tomography (HRCT) imaging of the temporal bones of the patients were retrospectively evaluated by 2 head and neck radiologists. Images were evaluated for the absence of the oval window, ossicular chain abnormalities, position of the facial nerve canal, and other malformations. Imaging findings were then correlated with surgical findings.@*RESULTS@#A total of 9 ears in 7 patients (two of whom with bilateral lesions) had surgery for OWA. All patients had concomitant findings of absent stapes footplate with normal, deformed or absent stapes superstructure and an inferiorly displaced facial nerve canal. HRCT was sensitive in identifying OWA and associated ossicular chain and facial nerve abnormalities, which were documented surgically.@*CONCLUSION@#OWA is a rare entity that can be diagnosed with certainty on HRCT, best visualised on coronal plane. Imaging findings of associated middle ear abnormalities, position of the facial nerve canal, which is invariably mal-positioned, and associated deformity of the incus are important for presurgical planning and consent.

ABSTRACT

The aim of this paper was to investigate the effect of Dingkun Dan on endometrial receptivity in rats with multiple lesions. Forty SD female rats with regular sexual cycle were randomly divided into 5 groups, control group, model group, progynova group, Dingkun Dan group and combination group. The thin endometrium model of kidney-yang deficiency was established in all the other rats except normal control group. The rats in normal control group were free to drink and eat; the rats in the model group were administered with distilled water; the rats in the progynova group were treated with progynova; rats in Dingkun Dan group were treated with Dingkun Dan, and the rats in combination group were treated with Dingkun Dan and progynova. After 15 days, serum levels of OPN, VEGF and MMP-9 were measured by ELISA. HE staining, immunohistochemistry and RT-PCR were used to analyze endome-trial morphology, endometrial thickness and the treatment mechanism of Dingkun Dan. As compared with the control group, the serum levels of OPN, VEGF and MMP-9 in the model group were significantly increased(P<0.01). As compared with the model group, the serum levels of OPN and MMP-9 were decreased in Dingkun Dan group(P<0.05, P<0.01). As compared with the control group, endometrial stromal cells were fewer, the endometrium glands and blood vessels were sparse, and the endometrium was thinner significantly in the model group(P<0.01). As compared with the model group, there were more endometrial glands, rich intimal vessels, and dense stromal cells in various treatment groups, and the endometrium were thickened significantly in the treatment groups(P<0.01). As compared with the control group, the expression area of CK19 in the model group was decreased significantly(P<0.01). As compared with the model group, the expression area of CK19 in each treatment group was increased significantly(P<0.05). As compared with the control group, endometrial β-catenin and MMP-9 mRNA expression levels were increased significantly in the model group(P<0.05), while VEGF mRNA expression was decreased(P<0.05). As compared with the model group, MMP-9 mRNA expression was decreased significantly in the progynova group and the combination group(P<0.05). Dingkun Dan combined with progynova can improve endometrial receptivity by up-regulating expression of β-catenin, VEGF mRNA and down-regulating the expression of MMP-9 mRNA in the injury rats.

ABSTRACT

Tripterygium wilfordii Hook F (TwHF) and its extracts have long been used for the treatment of rheumatoid arthritis, autoimmune diseases, and kidney disease due to their anti-inflammatory, immunoregulatory, and other pharmacological effects. However, the clinical immunoregulatory effects of TwHF and its extracts remain unclear, so we reviewed their effects for use in clinical practice. This review provides a comprehensive summary of the recent literature on the immunoregulatory effects of TwHF and its extracts in clinical studies. TwHF and its extracts affect the proliferation and activation of Tand B cells; ratio of Tcell subsets; inflammatory response of monocytes, macrophages, and immunoglobulins; and secretion of many cytokines. Together, these effects dictate immune function in a variety of diseases. TwHF and its extracts can be used alone or in combination with existing therapies against many immune disorders through immunomodulation.

ABSTRACT

A 68-year-old woman presented with weight loss of 7 kg over two years. Clinical examination revealed no specific abnormality and the patient was otherwise asymptomatic. Chest radiography performed to screen for malignancy revealed a soft tissue opacity projected over the mediastinum. Computed tomography of the thorax showed an enhancing anterior mediastinal mass with heterogeneous enhancement and contrast pooling in the arterial phase, followed by homogeneous enhancement in the venous phase, consistent with an aneurysm arising from the superior vena cava. This case highlights superior vena cava aneurysms as extremely rare causes of anterior mediastinal masses. Other causes of anterior mediastinal masses were also discussed.

ABSTRACT

OBJECTIVE@#To investigate the correlation between soluble receptor for advanced glycation end products (sRAGE) level in the follicular fluid and ovarian responsiveness in non-PCOS patients undergoing controlled ovarian hyperstimulation.@*METHODS@#Ninety non-PCOS patients underwent IVF/ICSI using a short-acting long protocol for ovarian stimulation with a GnRH agonist. For each patient, the level of sRAGE in the follicular fluid was measured by enzyme linked immunosorbent assay (ELISA), and the data including the clinical baseline state, hormone level, number of oocytes obtained and the fertilization rate were collected.@*RESULTS@#Follicular fluid sRAGE level showed significant negative correlations with basal FSH level (=0.0036) and Gn dose ( 15) than in cases with oocytes obtained within the range of the target numbers (7-15) and below the target number (< 7) ( < 0.0001 and =0.0012, respectively).@*CONCLUSIONS@#Follicular fluid sRAGE level can reflect ovarian reserve function in non-PCOS patients, the number of oocytes obtained and the fertilization rate, and can thus predict ovarian responsiveness during controlled hyperstimulation in nonPCOS patients.

ABSTRACT

Alzheimer's disease (AD) is characterized clinically as irreversible cognitive dysfunction. Although a significant progress has been made in the study of AD pathogenesis, the effective measures to block AD progress have not been satisfactory. Abnormal autophagy is thought to be involved in the pathogenesis of AD, and regulation of autophagy may become a new strategy for AD treatment. Some medicines, which regulate autophagy by mTOR-dependent and independent (Bcl-2/Beclin-1, GSK-3β, and p-AKT) pathways, have shown excellent effects in alleviating AD symptoms. In addition, certain compounds extracted from plants have also been reported to regulate autophagy and prevent AD progression through multiple pathways and multiple targets. This article reviews the recent advances in the regulation of autophagy and AD treatment. It provides a new theoretical basis for clinical treatment of AD.

ABSTRACT

Previous work has demonstrated that the sensitization of spinal neurons and microglia is important in the development of pain behaviors induced by BmK I, a Na channel activator and a major peptide component of the venom of the scorpion Buthus martensi Karsch (BmK). We found that the expression of P2X7 receptors (P2X7Rs) was up-regulated in the ipsilateral spinal dorsal horn after BmK I injection in rats. P2X7R was selectively localized in microglia but not astrocytes or neurons. Similarly, interleukin 1β (IL-1β) was selectively up-regulated in microglia in the spinal dorsal horn after BmK I injection. Intrathecal injection of P2X7R antagonists largely reduced BmK I-induced spontaneous and evoked pain behaviors, and the up-regulation of P2X7R and IL-1β in the spinal cord. These data suggested that the up-regulation of P2X7Rs mediates microglial activation in the spinal dorsal horn, and therefore contributes to the development of BmK I-induced pain.

ABSTRACT

The decreased efficacy and severe side effects of antibiotics, as well the increase of multidrug resistant pathogens are seriously threatening human health. It has become an urgent task for the whole world to actively respond to threats and establish effective prevention and control plans. Traditional Chinese medicine (TCM) has a long history with exact curative effect in the treatment of infectious diseases. It not only inhibits pathogens and eliminates endotoxin, but also has therapeutic effect on inflammation, immune abnormality and overall disorder caused by infection. Antibiotics mainly inhibit the pathogen itself, while the combination of TCM and antibiotics is complementary with each other and is considered as a feasible solution to the challenges. Some clinical observations have shown that TCM has potentiality of enhancing antibiotics efficiency and reducing toxicity. Exploring its mechanism is the necessary measure to optimize and popularize treatment regimen. Firstly, multi-level and multi-dimensional systematic pharmacology network analysis methods are used to predict the mechanism of TCM combined with antibiotics in the treatment of infectious diseases, so as to provide the evidence for further empirical research and selection of test indicators. Then by following the principle of corresponding drug use in specific TCM syndromes, the antibiotics and TCM are individually and jointly applied to treat patients with specific syndrome conditions of infectious diseases. Besides routine and comprehensive evaluation of synergistic and attenuated effect of the combined drug use, multi-omics technique is also used to find the subtle effects of these two drugs at a molecular level. The sensitive and stable clinical biomarkers of synergism and attenuation of combined drug use are determined by using biomolecular network analysis technology. Finally, taking these biomarkers as clues, the biotransformation process and regulation mechanism of the biomarkers are traced back in animal models of infectious diseases and cell level, and all of these are clinically verified. As a result, the mechanism of efficacy enhancing and toxicity reducing of combined drug use can be revealed, providing basis for the promotion and application of such combined drug use.

ABSTRACT

Objective:To observe the clinical efficacy of aspirin combined with modified Yupingfeng San on patients with recurrent spontaneous abortion and Seronegative antiphospholipid syndrome. Method:From December 2016 to March 2018, 109 cases of recurrent spontaneous abortion patients with seronegative antiphospholipid syndrome in Affiliated Hospital of Nanjing University of Chinese Medicine were selected as the study objects. According to the random number table, they were divided into three groups:blank group, control group and study group. The blank group was treated with folic acid tablets, 1 pill/time, qd, as placebo, the control group was treated with folic acid tablets, 1 pill/time, qd, Danshen pills, 4 pills/time, tid, and aspirin, 1 pill/time, tid, and the study group was treated with folic acid tablets, 1 pill/time, qd, aspirin, 1 pill/time, tid, and modified Yupingfeng San, 150 mL/time, bid. These patients were all asked for pregnancy preparation for 1 year and treated with aspirin, 1 pill/time, tid, and progesterone pills, 1 pill/time, tid, since the beginning of pregnancy until 13 weeks or abortion. The pregnancy rate, miscarriage rate, coagulation index before and after treatment, traditional Chinese medicine (TCM) symptom score as well as months of abortion were all observed and compared. Result:The coagulation index and TCM symptom score of the study group were significantly lower than those before treatment (PPPPPConclusion:The data proved that the combination of anti-coagulation medicine with either single herb or herbal compound can improve the curative effect of the patients, and traditional Chinese herbal compound can regulate the immune system, reduce the thrombosis and improve the symptoms of TCM, which made the curative efficacy more prominent. However, more samples were needed for further research. Because the time of fetal protection may not change the outcome of pregnancy, the therapy should be maintained at least until the end of the early pregnancy.

ABSTRACT

To explore the influence for combination of nourishing yin and tonifying yang sequential therapy (NYTYST) with Western medicine in treating anovulatory infertility rats with diminished ovarian reserve (DOR) based on TGF-β1/Smads signaling pathway. 
 Methods: A total of 40 female rats were randomly divided into 5 groups, a normal control group, a model group, a Western medicine group, a NYTYST group and a combination group (n=8 in each group). The DOR model was established through orally taking tripterygium pill for continuous 2 weeks. The normal control group and the model group were treated with saline for 10 days. The Western medicine group was treated with hormone replacement therapy (HRT) and ovarian stimulation. The NYTYST group was treated with nourishing yin herbs in proestrus and tonifying yang herbs in late estrus and the combination group was treated with Chinese herb and Western drugs for 10 days. HE staining was used to observe histopathologic changes in ovary. Expression levels of transforming growth factor β1 receptor (TGF-β1R) in rats ovarian were detected by immunohistochemistry. Expression levels of Smad2, Smad3 and Smad7 protein in rat ovarian were detected by Western blot.
 Results: Compared with the control group, the numbers of developing follicles, mature follicles and corpus luteum were decreased , while atrefic follicles were increased significantly in the model group (P<0.01); the levels of TGF-β1R, Smad2 and Smad3 were decreased significantly, while Smad7 was increased significantly (P<0.01). Compared with the model group, the numbers of developing follicles, mature follicles and corpus luteum, Smad2 and Smad3 expression were increased, while atrefic follicles and Smad7 were decreased significantly in the treatment group (P<0.05 or P<0.01). The numbers of developing follicles and corpus luteum in the combination group was superior to the Western medicine group (P<0.05). Compared with the Western medicine group, the levels of TGF-β1R, Smad2 and Smad3 were increased significantly, while Smad7 was decreased significantly in the combination group (P<0.05 or P<0.01). 
 Conclusion: NYTYST combined with Western medicine can improve the function of ovaries reserve by up-regulation of TGF-β1R, Smad2 and Smad3 while down-regulation of Smad7 in DOR rats.

ABSTRACT

There is still a need for better protection against or mitigation of the effects of ionizing radiation following conventional radiotherapy or accidental exposure. The objective of our current study was to investigate the possible roles of matrix metalloproteinase inhibitor, ilomastat, in the protection of mice from total body radiation (TBI), and the underlying protective mechanisms. Ilomastat treatment increased the survival of mice after TBI. Ilomastat pretreatment promoted recovery of hematological and immunological cells in mice after 6 Gy γ-ray TBI. Our findings suggest the potential of ilomastat to protect against or mitigate the effects of radiation.

ABSTRACT

Panax notoginseng is one of the most important traditional Chinese medicinal herbs, and it is mainly distributed in Yunnan and Guangxi Provinces and only can be planted in a very narrow geographical environment. Its yield is significantly limited by continuous cropping obstacles in the cultivation process, which has seriously affected the application and development of P. notoginseng. The dynamic patterns of root and soil rhizosphere microbial community response were main reasons for the continuous cropping obstacle. In this paper, the dynamic changes of the root and rhizosphere systems, pathogenic microorganisms and symbiotic microorganisms in the formation of P. notoginseng continuous cropping obstacles were analyzed, and the progress in this field was summarized. Two methods for studying soil and root microorganism of continuous cropping process are proposed: 1. The dynamic analysis of microorganism in the rhizosphere and root of P. notoginseng must be completed with the method of pure-culture and culture-independent; 2.
