To establish a sensitive and specific method for simultaneous determination of gestodene, etonogestrel and ethinylestradiol in plasma by LC-MS/MS, plasma samples were extracted and derivatized before injection. An ESI ion source was used and operated in the positive ion mode with multiple reaction monitoring (MRM). Norgestrel was chosen as internal standard and performed on a C18 (100 mm x 2.1 mm, 5 microm) column. The concentrations of gestodene, etonogestrel and ethinylestradiol were measured, using step-gradient mobile phase and step-gradient flow rate. The method was validated over the concentration range of 0.1-20 ng x mL(-1) for gestodene and etonogestrel and 0.01-2 ng x mL(-1) for ethinylestradiol, and showed excellent linearity. The intra- and inter-assay accuracy and precision were below 10.0% and recovery was 93.6%-110.9% over the three concentration levels evaluated. The method was applied in pharmacokinetic study of the compound gestodene patch and the compound etonogestrel patch in rabbits. The LC-MS/MS method was selective, accurate and sensitive, especially the LOQ were 100 pg x mL(-1) for gestodene and etonogestrel and 10 pg x mL(-1) for ethinylestradiol. The method was successfully applied in pharmacokinetic study for contraceptives.

Objective To investigate the cardiac protection of Hsp27 against endotoxic cardiac depression mediated by activation of PI3K/Akt pathway and the suppression of NFκB-mediated inflammatory response in mice. Method (1) Transgenic mice with cardiac specific overexpression of Hsp27 (Hsp27 Tg) and wild littermate controls (WT) were given 10 mg/kg LPS injected intraperitoneally to induce endotoxemia, (2) The cardiac function measurement in mice was performed by using echocardiography 6 hours after LPS treatment (n = 6), (3) The activity of PBK/Akt pathway was evaluated by Western blot for [hosphor-Akt (p-Akt) and phosphor-Gsk-3β (p-Gsk-3β) one hour after LPS administration ( n = 4)], (4) Activity of inflammatory response was evaluated by protein degradation of IκBα (n = 4), (5) The apoptosis of myocardial cells was determined by TUNEL assay on the paraffin section of cardiac tissue 24 hours after LPS exposure (n = 4). Results (1) Hsp27 attenuated cardiac dysfunction significantly following LPS treatment. Compared with the primary value, LPS induced the depression of cardiac function both in WT rats and Hsp27Tg rats. However, the cardiac dysfunction was attenuated significantly in Hsp27Tg rats compared with that in WT rats ( P < 0.01 or 0.05) . (2) Hsp27 attenuated IκBα degradation after LPS administration. Compared with the primary value, LPS led to LκBα degradation by (72.92 + 9.20) % in WT rats and by (41.43 + 24.10) % in Hsp27Tg rats. The overexpression of Hsp27 lessened the IκBα degradation significantly (P < 0.05). The similar results were obtained in rat myocardial cell culture of experiments. (3) Hsp27 enhanced the activation of PI3K/Akt signaling following LPS exposure. One hour after LPS administration, the relative levels of p-Akt and p-GSK-30 were (3.11 + 0.83) and (3.19 + 1.04), respectively in WT rats, and (5.13 + 0.73) and (5.71 + 1.20) in Hsp27Tg rats, respectively. Compared with WT rats, the levels of p-Akt and p-GSK-3β were significantly higher in Hsp27Tg rats (P < 0.05). (4) The Hsp27 lessened LPS-induced the apopto-sis of myocardial cells. Twenty-four hours after LPS treatment, the percentages of myocardial cell apoptosis were (6.46+ 1.74)% in WT rats and (2.88 + 0.91)% in Hsp27Tg rats. Compared with WT rats, LPS-induced apoptosis in myocardial cells was significantly decreased in Hsp27Tg rats (P < 0.01). Conclusions The overexpression ofHsp27 attenuates cardiac dysfunction significantly during endotoxemia, and the mechanisms may be attributed to the activation of PDK/Akt signaling pathway.

Objective:To investigate the iodine content distribution of drinking water in Jiangsu Province.Methods:In 2017, the iodine content in drinking water of residents in townships (streets, hereinafter referred to as townships) of Jiangsu Province was investigated. Administrative villages (neighborhood committees, hereinafter referred to as administrative villages) of Jiangsu Province were selected as units for the investigation of townships with the median water iodine greater than 10 μg/L. Delimitation criteria: the median iodine content of water < 40 μg/L was iodine deficiency area, 40-100 μg/L was suitable iodine area, and > 100 μg/L was high iodine area.Results:A total of 1 285 townships were surveyed in 101 counties (cities, districts) in 13 cities, and the median water iodine in townships was 7.28 μg/L. Among them, there were 875 townships with median water iodine < 10 μg/L, accounting for 68.09%; 315 townships 10-< 40 μg/L, accounting for 24.51%; 56 townships 40-100 μg/L, accounting for 4.36%; 39 townships > 100 μg/L, accounting for 3.04%. The water iodine survey at the administrative village level was conducted in 5 864 administrative villages in 410 townships in 6 cities. Among them, 769 administrative villages with median water iodine < 10 μg/L, accounting for 13.11%; 3 558 administrative villages 10 - < 40 μg/L, accounting for 60.68%; 613 administrative villages 40 - 100 μg/L, accounting for 10.45%; and 924 administrative villages > 100 μg/L, accounting for 15.76%.Conclusion:According to the water iodine, there are iodine deficiency, suitable iodine and high iodine areas in Jiangsu Province, mainly in iodine deficiency areas.

Objective To study the effects of heat shock proetin 27(Hsp27)on the cardiac dysfunction induced by endotoxemia.Method All experiments were performed in the geriatric lab of the First Affiliated Hospital Of Nanjing Medical University,and in the Animal Model Center of Nanjing University.The genotyping of the transgenic mice with cardiac-specific overexpression of Hsp27(Hsp27 Tg)was assayed by PCR and the expression of Hsp27 was determined by western blot.Hsp27 Tg and its wild type littermates(WT)were intraperitoneally injected with LPS(10 mg/kg),and 24 hours later,cardiac function was measured by echocardiography(n=6/group).The accumulated mice mortality was recorded within 70 hous after intraperitoneal injection of LPS(20mg/kg)(n=37/WT,n=27/Hsp27Tg).The NF-kB activity for cardiac-tissue samples was analyzed by electrophoretic mobility shift assay(ENSA)and for cell culture samples by dual-reporter gene assay(n=4/group).The comparison of multiple groups was performed by one-way analysis of variance(ANOVA),and comparison of two groups was performed by Scheffe-test.Survival curves were analyzed by the log-rank test.P＜0.05 wns considered to be significant.Results The high expression of Hsp27 exhibited in myocardium of Hsp27 Tg,whereas not in myocardium of WT.LPS significantly reduced the cardiac function both in Hsp27 Tg and WT.However,compaled with LPS-treated WT,cardiac function was more significantly improved as evidenced by the increases of EF by 27.33%and FS by 37.09%(P＜0.01 or P＜0.05).Seventy hours after LPS injection,the mortality was 11.11% in Hsp27 Tg and 37.84% in WT.Compared with WT,the survival rate of Hsp27 Tg significantly increased(P＜0.05).The NF-kB activation was significantly inhibited by Hsp27(P＜0.01 or P＜0.05).Conclusions The high cardiac-specific expression of Hsp27 significantly inhibits cardiac dysfunction induced by endotoxemia,and at the same time improve the survival rate.The mechanism may be connected with Hsp27 downregulating NF-kB-activation induced by LPS.

Objective:To investigate the effects of Bifidobacterium animalis subsp. lactis BB-12 on hippocampal neuroinflammation and cognitive function of mice after whole brain radiotherapy. Methods:A total of sixty male C57BL/6J mice aged 7-8 weeks were randomly divided into 5 groups with 12 mice in each group: control group (Con group), probiotic group (BB-12 group), irradiation group (IR group), irradiation and Memantine group (IR+ Memantine group), irradiation and probiotic group (IR+ BB-12 group). The model of radiation-induced brain injury of mice was established by 10 Gy whole brain radiotherapy with a medical linear accelerator. Y-maze test was used to evaluate the cognitive function. The activation of microglia and astrocytes was observed by immunofluorescence staining. The expressions of inflammatory cytokines interleukin-1β (IL-1β), IL-6 and tumor necrosis factor-α (TNF-α) were detected by quantitative real-time reverse transcription polymerase chain reaction (QRT-PCR) and Western blot.Results:Y-maze test showed that, compared with Con group, the percentage of the times of reaching the novel arm in the total times of the three arms decreased significantly in the IR group ( t=5.04, P<0.05). BB-12 mitigated radiation-induced cognitive dysfunction ( t=4.72, P<0.05). Compared with Con group, the number ( t=3.05, 7.18, P<0.05) and circularity index ( t=6.23, 2.52, P<0.05) of Iba1 and GFAP positive cells were increased, the microglia and astrocytes were activated in the hippocampus of IR group, but these alterations were eliminated by BB-12. After whole brain IR, the mRNA and protein expression levels of inflammatory cytokines IL-1β, IL-6 and TNF-α in the hippocampus of mice were significantly increased compared with Con group ( tmRNA =4.10, 3.04, 4.18, P<0.05; tprotein=11.49, 7.04, 8.42, P<0.05), which were also significantly reduced by BB-12 compared with IR group ( tmRNA=4.20, 3.40, 2.84, P<0.05; tprotein=6.36, 4.03, 3.75, P<0.05). Conclusions:Bifidobacterium animalis BB-12 can suppress neuroinflammation mediated by microglia and astrocytes in the hippocampus of mice after radiotherapy and alleviates IR-induced cognitive dysfunction. Therefore, BB-12 has potential application in alleviating radiation induced brain injury.

Objective To evaluate the impact of overall burden of cerebral small vessel disease(CSVD)combined with intracranial large artery atherosclerosis(ICAS)on cognitive function in very old patients.Methods A total of 178 advanced elderly patients admitted to Department of General Medicine of Wuhan Central Hospital between January 2013 and December 2022 were re-cruited in this retrospective study.According to the results of Montreal Cognitive Assessment Scale,they were divided into dementia group(n=83)and non-dementia group(n=95).All pa-tients underwent brain MRI imaging,MRI susceptibility weighted imaging and cerebral angiogra-phy.Based on these imaging findings of MRI,the effect of total burden score of CSVD and athero-sclerosis on cognition were evaluated.The volumes of 14 different gyri in the left and right brain were measured in the patients with CSVD burden score ≤2 and those ≥3.Results There were significantly more patients with numbers of microbleeding foci＞10 and lacunar foci ≥5 in the dementia group than the non-dementia group(P＜0.01).But,no statistical difference was seen in intracranial and extracranial arterial stenosis between the two groups(P＞0.05).The volumes of left and right anterior cingulate gyrus,left and right paracingulate cortex,right hippocampus,left parahippocampal gyrus,right transverse temporal gyrus and left inferior temporal gyrus were no-tably smaller in the CSVD score ≥3 group than the CSVD ≤2 group(1723.444 vs 1867.167,1590.167 vs 1595.670,1481.466 vs 1509.540,1543.831 vs 1585.505,1038.345 vs 1305.831,1220.525 vs 1392.352,P＜0.05).Conclusion Cognitive function in the advanced elderly is mainly affected by the burden of CSVD,and atherosclerotic stenosis of large arteries is not the main fac-tor affecting cognitive function.The total burden of CSVD is correlated with atrophy of some gyri.

Objective To explore the effects of Humulus lupulus L. extract (HLE) and xanthohumol (XN) on preventing glucocorticoid-induced osteoporosis (GIOP). Methods The GIOP model was established by intraperitoneal injection of dexamethasone (DEX). Bone microstructure, bone mineral density and serum biochemical indexes were evaluated by Micro-CT and ELISA kits. The levels of cells proliferation and ALP activity, and the expression of bone formation related proteins were assayed with primary osteoblasts injured by DEX. Results HLE and XN significantly alleviated the bone microstructure damage, enhanced the bone mineral density, and improved the trabecular parameters in GIOP mice. In vitro experiments showed that HLE and XN can prevent bone loss not only by improving cell proliferation and ALP activity, but also through increasing the expression of bone γ-glutamic acid-containing proteins (BGP), bone morphogenetic protein 2 (BMP-2) and runt-related transcription factor 2 (Runx-2). Conclusion This study confirmed that HLE and XN had anti-GIOP effects for the first time. It provides a new resource for the development of anti-osteoporosis medications.
