Objective · To observe effect of 17β estrodial (17β E2) with different concentrations on C type natriuretic peptide (CNP), insulin like growth factor 1 (IGF1), and natriuretic peptide receptor B (NPR-B) expression and proliferation of growth plate chondrocytes of rats in vitro. Methods · Eight Wistar rats were sacrificed and their epiphyseal cartilages of the upper tibias were separated to obtain chondrocytes on the 14th day after birth. Then chondrocytes were cultured with 17β E2 in different concentrations (10-4、10-6、10-8、10-10 and 10-12 mol/L) for 48 h, while control group was cultured without 17β E2. CCK8 method, ELISA and qRT-PCR were used to analyze the proliferation of chondrocytes, the levels of CNP and IGF1 in culture medium and mRNA levels of CNP, NPR-B and IGF1, respectively. Results · 17β E2 in different concentrations affected the proliferation of growth plate chondrocytes significantly. When the concentration of 17β E2 was 10-8 mol/L, it had the strongest effect on the cell proliferation. When the concentration increased to 10-4 mol/L, the proliferation of chondrocytes was inhibited. With the increasement of 17β E2 concentration, the levels of CNP in the culture medium and the mRNA levels of CNP in the chondrocytes were significantly different. The highest levels of CNP protein and mRNA both appeared in 10-8 mol/L group, while the lowest levels both appeared in 10-4 mol/L group. IGF1 and its mRNA also reached the highest levels in 10-8 mol/L group,but the lowest concentration and mRNA level were in 10-10 mol/L group and 10-12 mol/L, respectively. Both CNP mRNA and protein levels were positive correlated with the proliferation of chondrocytes (P=0.000). Nevertheless, there was no significant correlation between the proliferation of chondrocytes and IGF1 mRNA or protein levels (P>0.05). Conclusion · 17β E2 modulates proliferation of rat growth plate chondrocytes in a dose-effect manner. It enhances proliferation at relatively low concentrations (10-10-10-8 mol/L) and inhibits proliferation at high concentration. This effect is positively related to CNP expression in chondrocytes.

Objective To study the early diagnostic predictors and key follow-up parameters for girls with rapidly progressive central precocious puberty (RP-CPP). Methods A total of 260 girls with CPP participated in a prospective, nonrandomized, multi-center, nested case control study. After follow-up six months without any therapy, 114 girls were divided into RP-CPP (n=70) and slowly progressive CPP (SP-CPP) (n=44) groups. Results The basal serum LH and insulin-like growth factor Ⅰstandard deviation score (IGF-ⅠSDS) were the important risk factors of RP-CPP (OR 4.04, 1.578), especially the former. The receiver operating characteristic (ROC) curve revealed that the areas under the ROC curve of basal LH and IGF-ⅠSDS were 0.83 and 0.807, respectively. The levels of basal LH and IGF-ⅠSDS were at 0.52 mIU/ml and 0.35 respectively for the accuracy diagnosis of RP-CPP with the maximum Youden indexs. After follow-up for six months, the change levels of height, breast stages, bone age/chronological age ratio, serum LH, uterine and ovarian volume in RP-CPP group were significantly higher than those in SP-CPP group (all P<0.05). Conclusions The level of basal serum LH and IGF-ⅠSDS may be used as the risk predictors for early diagnosis for girls with RP-CPP. The change levels of basal LH, progress rates of gonad and sex character, height, and impaired growth potential seem to be the key follow-up parameters for CPP progress.

PTPN11 is the most common mutation gene of RAS disease, which is located in the upstream of RAS/MAPK pathway and participates in signal transduction. Because the molecular mechanism of RAS's disease involves the same pathway, it may present a certain commonality in clinic, but the different genotypes with PTPN11 mutation may also express different phenotypes. Therefore, it is not easy to identify and diagnose this disease early in clinic. The present article aims to analyze the correlation between the clinical phenotype and genotype of 4 patients with RAS disease.

OBJECTIVE To analyze the clinical manifestations and characteristics of adverse drug reactions (ADR) induced by dronedarone,and to provide reference for clinically safe drug use. METHODS Retrieved from PubMed database, Wanfang database,CNKI and VIP (up to August 31st, 2022),ADR cases of dronedarone were analyzed retrospectively in respect of patient’s age,gender,nationality,usage and dosage of dronedarone,and occurrence time,clinical manifestations,treatment measures and outcome of ADR,etc. RESULTS A total of 26 case reports were included,with a total of 27 patients. The age of the patients was 41-86 years old,with an average age of 68.8 years. The proportion of patients aged 60-79 was the largest (20 cases,74.1%). There was no significant difference in the number of males (14 cases) and females (13 cases). The patients came from 6 countries, of which the United States was the largest (16 cases,59.3%). The dosage of 14 patients was 400 mg bid;one patient was 200 mg bid;the dosage for 12 patients was not specified. The most ADR cases (16 cases,59.3%) occurred within 1 month,of which 11 cases(40.7%) occurred within 1 week,and there were no ADR reports with medication more than 12 months. Organs/systems involved in ADRs were mainly liver and biliary diseases (7 case times,23.3%),skin and subcutaneous tissue diseases (6 case times, 20.0%),respiratory tract,thoracic and mediastinal diseases (5 case times,16.7%). In addition,ADR also occurred in heart diseases, kidney and urinary system diseases,vascular diseases,medical examinations and eye diseases. Among 27 patients,there were 3 cases of death,the ADR were bronchiolitis obliterans with organizing pneumonia,toxic epidermal necrolysis and hepatic failure, respectively. One patient underwent liver transplantation. CONCLUSIONS Dronedarone can cause multiple organ system ADR. Before use,it is necessary to improve the examination including ECG,liver function,lung function,etc. and strengthen drug use monitoring within one month after the start of use,especially the ADR of hepatobiliary,skin and respiratory system. The occurrence of severe ADR has no obvious relationship with the duration of medication; even if it is taken safely for a long time,it still needs continuous pharmaceutical monitoring and follow-up to ensure the clinical medication safety of patients.

OBJECTIVE To investigate the role of the complement C3/C3aR signaling pathway in the prefrontal cortex and colon neuroglia cell interactions during meth-amphetamine(METH)addiction,to observe the effects of TLR4 inhibitors as well as complement C3 elimination on METH reward and relapse behavior,and to explore the neuroinflammatory mechanisms of complement C3 acti-vation in METH addiction.METHODS ①A 14 d and 28 d rat METH addiction model was established to observe the effects of TLR4 antagonist ibudilast 3 mg·kg-1 and 10 mg·kg-1 on self-administration,reward motivation,relapse,and natural reward behavior in METH-trained 14 d rats and the effects of 0.02 mg·kg-1 complement C3 antago-nist on self-administration behavior in METH-trained 28 d rats.② Differences in the expression of TLR4,NF-κB,GRP94,C3,cathepsin L,CD68,and GFAP in the pre-frontal cortex of each group were examined using West-ern blotting.③ In addition,the expression of ATF6 in the prefrontal cortex of each group and the effects on neuro-nal and microglia/macrophage INOS,CD206 GRP94,and complement C3/C3aR.RESULTS ① Endoplasmic reticulum stress occurred in neurons and microglia after METH exposure depending on GRP94 and unfolded pro-tein responses to the ATF6 pathway.In addition,it acti-vates the TLR4-NF-κB pathway.② Microglia with high complement C3/C3aR expression in the prefrontal cortex were recruited to synaptic pruning and phagocytic responses around neurons with high GRP94,comple-ment C3/C3aR expression and these effects were blocked by complement C3 antagonists.③ In the rec-tum,GRP94 functions as a molecular chaperone for com-plement C3 and cathepsin L.Crosstalk occurs between enteric neurons high in GRP94,complement C3,and macrophages high in C3aR,located in the submucosa,lamina propria,and muscular,respectively,and all of these effects are blocked by complement C3 antago-nists.④ Treatment with the TLR4 antagonist ibudilast inhibits self-administration,reward motivation,and cue-or METH-priming in METH-trained 14 d rats,but fails to affect natural reward behavior.Ibudilast treatment attenu-ates the TLR4-NF-κB inflammatory pathway and comple-ments C3/C3aR pathway in the prefrontal cortex.CON-CLUSION Activation of the complement C3/C3aR signal-ing pathway by TLR4-NF-κB inflammatory signaling in the prefrontal cortex mediates the METH addiction pro-cess,providing an experimental basis for the clinical treatment of METH addiction,and targeting TLR4/NF-κB inflammatory signaling and complement C3/C3aR may be a new way to intervene in METH addiction.
