Objective To investigate the relationship between serum adiponectin levels and body composition of perimenopausal and postmenopausal women in central and western Gansu province, and explore the influencing factors of adiponectin levels. Methods The body weight, body mass index(BMI), waist-to-hip, fat mass, percentage of body fat, visceral fat mass and muscle mass of 638 women(317 in perimenopausal period and 321 in postmenopausal period) in central and western Gansu were measured by bioelectrical impedance analyzer. Enzyme linked immunosorbent assay (ELISA)was used to measure serum adiponectin levels. Pearson correlation analysis and multiple liner regression were used to investigate the relationship between adiponectin levels and body composition. Results The body muscle mass of women living in central and western Gansu province showed a downward trend after menopause period compared to those who were in perimenopause. The waist circumference, waist-hip ratio, percentage of body fat, visceral fat mass of postmenopauseal women showed an increasing trend compared to perimenopausal. There were no significant differences in BMI, fat mass and serum adiponectin levels. Overall, serum adiponectin levels were positively correlated with body fat percentage and visceral fat mass, and negatively correlated with muscle mass, and the main influencing factors of serum adiponectin levels were visceral fat mass. Conclusion The main influencing factors of serum adiponectin levels in perimenopausal and postmenopausal women living in central and western Gansu province are the visceral fat mass.

Research advances on stimulator of interferon genes (STING) and its agonists / 药学学报

As a key signal transduction molecule involved in the innate immune response, stimulator of interferon genes (STING) is triggered by cytosolic DNA from pathogen and host origins, and plays an important role in inducing the secretion of type I interferons and proinflammatory cytokines, thereby defending against viral and intracellular bacterial infections and regulating the production of spontaneous antitumor immune responses in vivo. Thus, STING agonists have shown useful therapeutic effects for pathogen infection and cancer. In the past decade research on STING and its agonists has progressed rapidly. Here, we summarize recent advances in the structure and activation of STING and the mechanism of the cGAS-STING pathway. In particular, we review research advances of STING agonists, analyze the crystal structure of STING in complex with its agonists and the structure-activity relationship of STING agonists, and summarize the strong challenges of developing STING agonists.

Secondary injury in rats with intra-cerebral hematoma: a 7 Tesla high-field strength MRI study / 中华神经医学杂志

Objective To dynamically analyze the evolutionary process of cerebral edema absorption and the level of local iron in rats with intra-cerebral hematoma by high-field strength 7 Tesla MRI and explore the characteristics and mechanism of secondary injury after intra-cerebral hematoma.Methods Sixteen adult SD rats (about 150 g) were randomly divided into experimental group (n=10) and control group (n=6).Rat models in the experimental group were established by performing injection of 50 μL their own venous blood into their right caudate nucleus accurately. Rats in the control group were used normal saline,instead.After that,head MRI (T2 and T2-star scans) was performed 1,2,3,7 and 14 d after the injection; their imaging features were compared. Results Nine rats in the experimental group survived and 1 died after the operation; in the early days (within 3 d), the T2 weighing imaging showed that the time of relaxation surrounding the hematoma was longer than that in control group,suggesting that the zone of the edema surrounding the hematoma became more clearly.In the early days (within 3 d),T2-weighted imaging was clear,and the time of relaxation surrounding the hematoma increased rapidly,steadily improved 3 d after the operation and reached its peak level 7 dafter the operation; the damage area absorption decreased steadily but turned widening 3 d later and reached the peak 7 d later.T2-star value reached the peak rapidly 3 d after the operation,and then,moderated the downturn.The rats in the control group showed no obvious signal changes under MRI,except those with needle tract injury. Conclusion Secondary injury after intra-cerebral hemorrhage shows a rapidly injury progress in the short terrn at first,and then,has intensify again after a stable period; the local iron diffusion trend is synchronized to the secondary injury,suggesting that iron may play a key role in the mechanism of secondary brain edema.

Establishment of a cell-based 2009 H1N1 influenza neuraminidase inhibitors evaluation system / 药学学报

This study is to establish a cell-based model targeting to neuraminidase (NA) of the 2009 H1N1 influenza A virus. NA is an influenza virus structural protein with enzymatic activity of the cleavage of HA-sialic acid interaction to release new viral particles from cells. A model of HIV-1 (pNL4-3.Luc.R(-)E(-)) based pseudovirions packed with HA [hemagglutinin, A/VietNam/1203/2004 (H5N1)] and NA [A/California/04/2009 (H1N1)] was established to evaluate compounds activities on NA function. The viral release can be blocked by neuraminidase inhibitors, oseltamivir and oseltamivir carboxylate, with IC50 of (61 +/- 31) nmol L(-1) and (5.5 +/- 2.9) nmol L(-1) respectively. A point mutation of H275Y on NA leads oseltamivir-resistance. This corresponding mutation was introduced into the system which was also confirmed by oseltamivir and oseltamivir carboxylate.

Cell proliferation inhibited by TIP-6 through autophagy in human hepatoma cell line HepG2 and human normal hepatocyte cell line L02 / 细胞与分子免疫学杂志

AIM: To investigate the effect of 7-(4-methoxyphenyl)-5, 8a-diphenyl-1,2, 3, 7, 8, 8a-hexahydroimidazo[1,2-a] pyridine (TIP-6) on cell proliferation in human hepatoma cell line HepG2 and human normal hepatocyte cell line L02. METHODS: Typan blue assay was used to check the effect of TIP-6 on cell proliferation. The changes of cell morphology were observed by the phase contrast microscope. Flow cytometry (FCM) was used to check cell cycle. Autophagy and autophagic cell death were detected after acridine orange (AO) staining under fluorescent microscopy. Apoptosis was analyzed by Annexin V/7-AAD, DAPI staining and DNA ladder. NF-κB expression was detected with cellular immunochemistry. RESULTS: Cell proliferation inhibiting effect was appeared when treated with TIP6 from 60 μmol/L to 200 μmol/L, which was correlated with treated concentrations and time. The proliferation rates were just 12.10% and 18.75% (vs control) under 200 μmol/L 72 h in HepG2 and L02 respectively. Vacuolization were found more and more frequently with the increasing of TIP-6 concentrations and treated time prolonged. FCM results indicated that cells were blocked in G2/M phase, and more sensitive were found in HepG2 than L02. AO staining results indicated that the phenomenon of autophagy and autophagic cell death were occurred and appeared more potent with more TIP-6 and longer time treated. No apoptosis markers were found with Annexin V/7-AAD and DAPI staining, and no DNA ladders were found either, these indicated that TIP6 didnt induce apoptosis in these cells. NF-κB was found increased after treated with TIP-6, and the autophagic vacuole became more and more with the increasing of NF-κB protein, but the proliferation rates decreased at the same time. CONCLUSION: TIP-6 inhibited cell proliferation and induced autophagy and autophagic cell death in HepG2 and L02 cells. NF-κB activation may be involved in these effects.

Effects of α1-adrenergic receptor on the proliferation of cholangiocarcinoma cells / 中华消化外科杂志

Objective To investigate the correlation between α1-adrenergic receptor and the pathological behavior of cholangiocarcinoma, and the effects of norepinephrine (NE) on the proliferation of cholangiocarcinoma cell line QBC939. Methods Thirty-six samples of cholangiocarcinoma were resected in Southwest Hospital from August 2002 to March 2008. The expression of α1-adrenergic receptor in the 36 samples of cholangiocarcinoma tissue and 4 samples of normal bile duct tissue were detected by SABC technique. The proliferation of cholangio-carcinoma cell line QBC939 was detected after processing the cells with NE, phentolamine and prazosin. All the data were analyzed by chi-square test. Results The high positive expression rate of α1-adrenergic receptor was 68% (17/25) in patients with lymph node metastasis, which was significantly higher than 9% (1/11) in patients without lymph node metastasis (χ2=10.604, P<0.05). The high positive expression rate of α1-adrenergic receptor was 85% (11/13) in patients with middle and low positioned cholangiocarcinoma, which was significantly higher than 30% (7/23) in patients with hilar cholangiocarcinoma (χ2=9.753, P<0.05). NE promoted the proliferation of cholangiocarcinoma cell line QBC939 by stimulating the expression of α1-adrenergic receptor, and in a concentration-dependent manner. The proliferative effect was weakened as time passed by, and it was eliminated by phentolamine and prazosin. Conclusions The expression of α1-adrenergic receptor is diverse due to lymph node metastasis and the location of the tumor, α1-adrenergic receptor with high expression may play an important role in the proliferation and metastasis of cholangiocarcinoma.
