In recent years, neurotoxicity caused by traditional Chinese medicine (TCM) has frequently occurred and has become one of the important factors restricting the development and application of TCM. TCM contains active components and its dosage-effect relationship is the key to determine its pharmacological activity and toxic effects. Among them, the endogenous toxic components include alkaloids, glycosides, diterpenoids, animal and plant toxic proteins and heavy metals, and so on; exogenous toxic components mainly refer to some harmful elements and pesticide residues during the cultivation, processing, transportation and storage of medicinal materials that are not synthesized by themselves. Effect on the processes such as oxidative stress, inflammation, ion exchange, and energy metabolism may be important mechanisms of TCM-induced neurotoxicity. Neural cells, myelin cells, axons and neurotransmitter systems are common targets of TCM-induced neurotoxicity. In the future, we can use modern research methods and big data mining means to establish a safety evaluation mode of “toxic symptoms-poisoning dose-toxic original agent-detoxification scheme” with the basic component group of toxic substances as the core, so as to provide support for development and clinical intervention of neurotoxic traditional Chinese medicine.

ObjectiveTo investigate the effect and mechanism of Nongsuo Dangguiwan in improving ovarian oxidative stress in rats with ovarian dysfunction. MethodThirty-six adult female SD rats were randomly divided into normal group, model group, positive drug group (Femoston, 0.3 mg·kg-1), and high-, medium-, and low-dose groups of concentrated Nongsuo Dangguiwan (2.08, 4.16, 8.32 g·kg-1), with six rats in each group. Rats, except for those in the normal group, were injected with 80 mg·kg-1 vinyl cyclohexene dioxide (VCD) per day for 14 consecutive days to induce ovarian dysfunction. From the 15th day, rats were treated with corresponding drugs by gavage, while those in the model group received 2 mL·kg-1 saline, once daily for 28 consecutive days. The ovarian index, levels of related hormones including estradiol (E2), follicle-stimulating hormone (FSH), luteinizing hormone (LH), and anti-mullerian hormone (AMH) in serum, as well as superoxide dismutase (SOD) activity and glutathione (GSH) content in serum were measured by enzyme-linked immunosorbent assay (ELISA). The malondialdehyde (MDA) content in serum was detected by the thiobarbituric acid (TAB) method. Ovarian morphology was observed by hematoxylin-eosin (HE) staining. The expression of nuclear factor E2-related factor 2 (Nrf2), heme oxygenase-1 (HO-1), SOD2, and SOD1 in ovarian tissues was detected by immunohistochemistry (IHC) and Western blot. ResultCompared with the normal group, the model group showed a significant reduction in growing follicles in the ovary, loose arrangement of granulosa cells in the follicle, decreased body weight, ovarian index, and serum AMH and E2 levels, increased LH and FSH levels (P<0.01), reduced levels of SOD and GSH in serum (P<0.01), and increased MDA level (P<0.01). Compared with the model group, the groups with drug intervention showed increased ovarian index (P<0.05, P<0.01), increased serum E2 level (P<0.05, P<0.01), decreased FSH, AMH, and LH levels (P<0.05, P<0.01), increased number of growing follicles in the ovary, potentiated SOD activity in serum, increased GSH content, decreased MDA content (P<0.05, P<0.01), and up-regulated expression levels of Nrf2, HO-1, SOD2, and SOD1 proteins in ovarian tissues (P<0.05, P<0.01). ConclusionNongsuo Dangguiwan can regulate serum hormone levels, increase the expression of Nrf2, HO-1, SOD2, and SOD1 in ovarian tissues, and improve ovarian antioxidant capacity to resist oxidative stress injury, thereby improving ovarian reserve function.

ObjectiveTo explore the mechanism of Jianpi Yishen Huazhuo prescription in the improvement of ovarian function in polycystic ovary syndrome (PCOS). MethodSeventy female SD rats in SPF grade were randomly divided into 6 groups, 15 in the blank group and 15 in the model group, 10 in the metformin group (0.1 g·kg-1·d-1), and 10 in the low (1.275 g·kg-1·d-1), medium (2.55 g·kg-1·d-1), and high-dose (5.10 g·kg-1·d-1) Jianpi Yishen Huazhuo prescription groups. The blank group was given normal saline (10 mL·kg-1·d-1) by gavage and ordinary feed, and the other groups were given letrozole (1 mg·kg-1·d-1) by gavage combined with high-fat feed for 21 days to induce the model of PCOS. After modeling, the blank group and model group were given equal volume normal saline by gavage, and each drug group was given the corresponding dose of the drug by gavage for 30 days. The changes in body mass and fasting blood glucose (FPG) of rats before and after modeling were compared. Hematoxylin eosin (HE) staining was used to observe the morphological change in the ovaries of rats in each group. The serum levels of follicle stimulating hormone (FSH), luteinizing hormone (LH), testosterone (T), anti-Mullerian hormone (AMH), and estradiol (E2) were measured by enzyme-linked immunosorbent assay (ELISA), and the LH/FSH ratio was calculated. Immunohistochemical staining (IHC) and Western blot were used to detect the protein expression levels of nucleoside binding oligomerization domain protein like receptor 3 (NALP3), apoptosis-associated speck-like protein (ASC), cysteine protease-1 (Caspase-1), nuclear transcription factor-κB (NF-κB), interleukin-1β (IL-1β), interleukin-18 (IL-18), and interleukin-6 (IL-6) in the rat ovaries. ResultAs compared with the blank group, large follicles with polycystic expansion were found in the ovaries of the model group, no dominant follicles were found, the granular layer of follicles decreased and arranged loosely, and the number of corpus luteum decreased significantly. Serum T, LH, AMH and LH/FSH increased in the model group (P<0.05, P<0.01), while FSH and E2 decreased (P<0.05, P<0.01). The relative protein expression levels of NALP3, ASC, Caspase-1, NF-κB, IL-1β, IL-18, and IL-6 increased (P<0.05, P<0.01) in the ovaries of the model group. Compared with the model group, the low, medium, and high-dose Jianpi Yishen Huazhuo prescription groups and the metformin group showed growing follicles and corpus luteum at all levels, the number of cystic expanding follicles decreased, the thickness of follicular granular layer increased, the number of follicular fluid increased, mature follicles were visible, and the local morphology of oocytes was complete. Serum T, LH, AMH, and LH/FSH in these groups decreased (P<0.05, P<0.01), while E2 and FSH increased (P<0.05). The relative protein expressions of NALP3, ASC, Caspase-1, NF-κB, IL-1β, IL-18, and IL-6 in the ovaries of these groups decreased (P<0.05, P<0.01). There was no significant difference among the treatment groups. ConclusionBy inhibiting the activation of NLRP3 inflammasome, Jianpi Yishen Huazhuo prescription reduces the release of NALP3, ASC, Caspase-1, NF-κB, IL-18, IL-1β, and IL-6 inflammatory factors in ovarian tissues, regulates endocrine level, and effectively reduces PCOS inflammatory statu, so as to play a role in improving ovarian function.

Despite complications were significantly reduced due to the popularity of percutaneous coronary intervention (PCI) in clinical trials, reperfusion injury and chronic cardiac remodeling significantly contribute to poor prognosis and rehabilitation in AMI patients. We revealed the effects of HSP47 on myocardial ischemia-reperfusion injury (IRI) and shed light on the underlying molecular mechanism. We generated adult mice with lentivirus-mediated or miRNA (mi1/133TS)-aided cardiac fibroblast-selective HSP47 overexpression. Myocardial IRI was induced by 45-min occlusion of the left anterior descending (LAD) artery followed by 24 h reperfusion in mice, while ischemia-mediated cardiac remodeling was induced by four weeks of reperfusion. Also, the role of HSP47 in fibrogenesis was evaluated in cardiac fibroblasts following hypoxia-reoxygenation (HR). Extensive HSP47 was observed in murine infarcted hearts, human ischemic hearts, and cardiac fibroblasts and accelerated oxidative stress and apoptosis after myocardial IRI. Cardiac fibroblast-selective HSP47 overexpression exacerbated cardiac dysfunction caused by chronic myocardial IRI and presented deteriorative fibrosis and cell proliferation. HSP47 upregulation in cardiac fibroblasts promoted TGFβ1-Smad4 pathway activation and Smad4 deubiquitination by recruiting ubiquitin-specific peptidase 10 (USP10) in fibroblasts. However, cardiac fibroblast specific USP10 deficiency abolished HSP47-mediated fibrogenesis in hearts. Moreover, blockage of HSP47 with Col003 disturbed fibrogenesis in fibroblasts following HR. Altogether, cardiac fibroblast HSP47 aggravates fibrosis post-myocardial IRI by enhancing USP10-dependent Smad4 deubiquitination, which provided a potential strategy for myocardial IRI and cardiac remodeling.

Objective To study the role of C3a and C5a in focal segmental glomerulosclerosis (FSGS) patients. Methods (1) A total of 66 patients with FSGS confirmed by renal biopsy were selected, including 18 cases of tip lesion, 11 cases of perihilar, 22 cases of not otherwise specified (NOS), 10 cases of cellular, and 5 cases of collapsing FSGS. The normal renal tissue resected from patients with kidney tumor was taken as a negative control. The expression of C3a and C5a in renal tissues was detected by immunohistochemistry. (2) Serum and urine samples from these 66 FSGS patients were collected, and serum and urine samples from 10 healthy adult selected from the same physical examination center in the same term were used as normal controls. The levels of C3a and C5a in serum and urine were detected by enzyme - linked immunosorbent assay (ELISA). Results (1) Immunohistochemical results showed that C3a and C5a were deposited in glomerulus of FSGS patients, and no deposition in normal renal tissues. The semi - quantitative score showed that kidney C3a score was significantly correlated with serum creatinine (r=0.547, P<0.001) and 24 h urine protein (r=0.329, P=0.007) in FSGS patients, and kidney C5a score was also significantly correlated with serum creatinine (r=0.415, P<0.001) and 24 h urine protein (r=0.414, P<0.001) in FSGS patients. (2) The levels of serum C3a and C5a in FSGS patients were higher than those in healthy adults (both P<0.05), but there was no significant difference among the five pathological types (P>0.05). The levels of urinary C3a/urinary creatinine, urinary C5a/urinary creatinine were higher in FSGS patients than those in healthy adults (all P<0.05). The levels of urine C3a/urinary creatinine and urinary C5a/urinary creatinine in collapsing FSGS were higher than other FSGS types (all P<0.01), but there was no significant difference among the tip lesion, the perihilar, the not otherwise specified and the cellular (P>0.05). (3) Urinary C3a/urinary creatinine levels were significantly correlated with serum creatinine (r=0.774, P<0.001) and 24 h urine protein (r=0.430, P<0.001) in FSGS patients, and urinary C5a/urinary creatinine levels were also significantly correlated with serum creatinine (r=0.677, P<0.001) and 24 h urine protein (r=0.333, P=0.007) in FSGS patients. Conclusion Complement C3a and C5a may be involved in the pathogenesis of FSGS and may be related to the severity of FSGS.

BACKGROUND:Stem cel transplantation has gained considerable support recently. It provides new opportunities for treating diabetic neurogenic bladder. OBJECTIVE:To summarize the research progress in bone marrow mesenchymal stem cel s (BMSCs)transplantation in the treatment of diabetic neurogenic bladder. METHODS:The first author retrieved Sciencedirect, PubMed, Embase, Wangfang and CNKI databases, for relevant articles of BMSCs transplantation in the treatment of diabetic neurogenic bladder, published from 2000 to 2016. The key words were“bone marrow mesenchymal stem cel s, diabetic neurogenic bladder, differentiation, transplantation”in Chinese and English, respectively. RESULTS AND CONCLUSION:In patients with diabetic neurogenic bladder, the transplantation of BMSCs may provide safer and longer-lasting outcomes by repairing the damaged bladder and urethra. And it can produce various bioactive substances, which wil have nutritional paracrine effects on the bladder microenvironment, including anti-inflammation, promoting cel proliferation and improving cel survival. On the one hand, the BMSCs have the ability to migrate to the injury site via the blood circulation. On the other hand, BMSCs can produce various growth factors, as wel as the cytokines that can inhibit the inflammatory response. While the current clinical studies are lacking, its efficacy and safety needs further verification.
