Objective To investigate the occurrence of adverse events of lurasidone in the U.S.Food and Drug Administration Adverse Event Reporting System(FAERS)database by using Open Vigil FDA2.1,to enrich the experience and provide the basis for the clinical use of the drug in China.Methods Using Open Vigil FDA2.1,adverse event data were extracted from the FAERS database for a total of 51 quarters from the 4th quarter of 2010 to the 3rd quarter of 2023,and the ratio of reporting ratio(ROR)method and the proportional reporting ratio(PRR)method were used for data mining and analysis.Results A total of 32 728 adverse event reports with lurasidone as the first suspected drug was obtained,with a larger proportion of females(54.26％)and occurring mostly in adults(18 to 59 years).After the screening,326 preferred term(PT)signals were obtained,involving 20 system-organ classifications(injury,poisoning and procedural complications,general disorders and administration site conditions,psychiatric disorders,etc.).Among them,PTs with the higher frequency of occurrence included off label use,feeling abnormal,crying,anxiety,depression,insomnia,etc.PTs with stronger signal strength included activation syndrome,mania,tongue movement disturbance,hypoprolactinaemia,akathisia,etc.Multiple new suspected adverse drug reactions were unearthed,including hypoprolactinaemia,emotional poverty,stiff tongue,etc.Conclusion Lurasidone has a favorable safety profile,and women need to closely monitor prolactin levels when taking this medication.The drug is relatively safe for use in pregnant,puerperal and perinatal women and patients with poor metabolic function.Hypoprolactinaemia and restless leg syndrome are new rare suspected adverse events with lurasidone.

Objective: To investigate the relationship between body mass index (BMI) and sexual development in Chinese children. Methods: A nationwide multicenter and population-based large cross-sectional study was conducted in 13 provinces, autonomous regions and municipalities of China from January 2017 to December 2018. Data on sex, age, height, weight were collected, BMI was calculated and sexual characteristics were analyzed. The subjects were divided into four groups based on age, including ages 3-<6 years, 6-<10 years, 10-<15 years and 15-<18 years. Multiple Logistic regression models were used for evaluating the associations of BMI with sexual development in children. Dichotomous Logistic regression was used to compare the differences in the distribution of early and non-early puberty among normal weight, overweight and obese groups. Curves were drawn to analyze the relationship between the percentage of early puberty and BMI distribution in girls and boys at different Tanner stages. Results: A total of 208 179 healthy children (96 471 girls and 111 708 boys) were enrolled in this study. The OR values of B2, B3 and B4+ in overweight girls were 1.72 (95%CI: 1.56-1.89), 3.19 (95%CI: 2.86-3.57), 7.14 (95%CI: 6.33-8.05) and in obese girls were 2.05 (95%CI: 1.88-2.24), 4.98 (95%CI: 4.49-5.53), 11.21 (95%CI: 9.98-12.59), respectively; while the OR values of G2, G3, G4+ in overweight boys were 1.27 (95%CI: 1.17-1.38), 1.52 (95%CI: 1.36-1.70), 1.88 (95%CI: 1.66-2.14) and in obese boys were 1.27 (95%CI: 1.17-1.37), 1.59 (95%CI: 1.43-1.78), and 1.93 (95%CI: 1.70-2.18) (compared with normal weight Tanner 1 group,all P<0.01). Analysis in different age groups found that OR values of obese girls at B2 stage and boys at G2 stage were 2.02 (95%CI: 1.06-3.86) and 2.32 (95%CI:1.05-5.12) in preschool children aged 3-<6 years, respectively (both P<0.05). And in the age group of 6-10 years, overweight girls had a 5.45-fold risk and obese girls had a 12.54-fold risk of B3 stage compared to girls with normal BMI. Compared with normal weight children, the risk of early puberty was 2.67 times higher in overweight girls, 3.63 times higher in obese girls, and 1.22 times higher in overweight boys, 1.35 times higher in obese boys (all P<0.01). Among the children at each Tanner stages, the percentage of early puberty increased with the increase of BMI, from 5.7% (80/1 397), 16.1% (48/299), 13.8% (27/195) to 25.7% (198/769), 65.1% (209/321), 65.4% (157/240) in girls aged 8-<9, 10-<11 and 11-<12 years, and 6.6% (34/513), 18.7% (51/273), 21.6% (57/264) to 13.3% (96/722), 46.4% (140/302), 47.5% (105/221) in boys aged 9-<10, 12-<13 and 13-<14 years, respectively. Conclusions: BMI is positively correlated with sexual development in both Chinese boys and girls, and the correlation is stronger in girls. Obesity is a risk factor for precocious puberty in preschool children aged 3-<6 years, and 6-<10 years of age is a high risk period for early development in obese girls.

Objective To evaluate the uncertainty in the determination of lamotrigine (LTG) in human serum with high performance liquid chromatography (HPLC).Methods It was analyzed that the influences of various factors for detection results,including weighing,solution preparation,serum extraction,calibration curve fitting repeatability and so on.The expanded uncertainty was evaluated and combined by each component of uncertainty.Results The expanded uncertainty of lamotrigine at low (1.50 μg · mL-1),middle (8.00 μg · mL-1),high (20.00 μg · mL-1) concentrations were UL =0.30,UM =0.53,UH =0.98,respectively (P =95％,k =2).The corresponding test concentration were (1.51 ±0.30),(8.22±0.53),(20.40±0.98) μg · mL-1,respectively.Conclusion The relative uncertainty on the determination of lamotrigine in human serum by HPLC was mainly caused by repeatability,calibration curve fitting and extraction recovery;repeatability and calibration curve fitting were the important factor in influencing the results of low concentrations.

To study effects of APG, Span-Tween and A6/25 emulsifier cream system on transdermal absorption in vitro of baicalin, matrine, glycyrrhetinic acid and emodin in emulsifier. Permeations studies were carried out in vitro with excised mice skin by improved Franz diffusion cells. The cumulative penetration amounts and the retention amounts of Chinese herbal medicinal ingredients in three kinds of emulsifier cream systems were determined by HPLC. The effects of different Chinese herbal medicinal ingredients in the same emulsifier system and the same herbal medicinal ingredients in different emulsifier systems on cumulative permeation amount, skin retention amount and permeation rate were investigated. According to the results, the order of different Chinese herbal medicinal ingredients in same kinds of emulsifier system by the cumulative permeation amount and the permeation rate were matrine>baicalin>glycyrrhetinic acid>emodin. With respect to the effect of different emulsifier systems on cumulative permeation amount and permeation rate of the same herbal medicinal ingredients, glycyrrhetinic acid and emodin showed no significant difference, Span-Tween emulsifier cream system had higher cumulative permeation amount and permeation rate. The cumulative permeation amount and the permeation rate of Chinese herbal medicinal ingredients in the three kinds of emulsifier cream systems had an identical regularity. However, the cumulative permeation amount, the skin retension amount and the permeation rate of the same herbal medicinal ingredients in different emulsifier systems had no regularity.

OBJECTIVETo explore the protection of high intensity microwave radiation on hypothalamo-pituitary-adrenal axis (HPAA) activity and hippocampal CA1 structure in rats and the protectiveeffect of Qindan Granule (QG) on radiation injured rats.

METHODSTotally 48 Wistar rats were randomlydivided into 8 groups, i.e., the normal control group, post-radiation day 1, 7, and 10 groups, 7 and 10days prevention groups, day 7 and 10 treatment groups, 6 in each group. Rats in prevention groups wererespectively administered with QG liquid (1 mL/100 g, 4. 75 g crude drugs) for 7 days and 10 days bygastrogavage and then microwave radiation. Then preventive effect for radiation injury was statisticallycalculated with the normal control group and the post-radiation day 1 group. Rats in treatment groupswere firstly irradiated, and then administered with QG liquid (1 mL/100 g, 4.75 g crude drugs). Finally preventive effect for radiation injury was statistically calculated with the normal control group, post-radiation day 7 and 10 groups. Contents of corticotrophin releasing hormone (CRH), beta endorphin (beta-EP), adrenocorticotropic hormone (ACTH), and heat shock protein 70 (HSP70) were detected. Morphological changes and structure of hippocampal CA1 region were observed under light microscope.

RESULTSCompared with the normal control group, contents of CRH and beta-EP significantly decreased in each radiation group. Serum contents of ACTH and beta-EP significantly increased in post-radiation day 1 and 7 groups (P < 0.05). Compared with radiation groups, beta-EP content in serum and pituitary significantly increased, and serum ACTH content significantly decreased in prevention groups (P < 0.05). Pituitary contents of CRH and beta-EP significantly increased in prevention groups. Serum contents of ACTH, beta-EP, and HSP70 were significantly lower in day 7 treatment group than post-radiation day 7 group (P < 0.05). Morphological results showed that pyramidal neurons in the hippocampal CA1 region arranged in disorder, with swollen cells, shrunken and condensed nucleus, dark dyeing cytoplasm, unclear structure. Vessels in partial regions were dilated with static blood; tissues were swollen and sparse. In prevention and treatment groups pathological damage of hippocampal CA1 region was obviously attenuated; neurons were arranged more regularly; swollen, pycnotic, or deleted neuron number were decreased; vascular dilatation and congestion was lessened.

CONCLUSIONQG could affect HPAA function and activity of high intensity microwave radiated rats, showing certain preventive and therapeutic effects of microwave radiated rats by adjusting synthesis and release of partial bioactive peptides and hormones in HPAA, improving pathological injury in hippocampal CA1 region.

Sex hormone estrogen is one of the most active intrinsic angiogenesis regulators; its therapeutic use has been limited due to its carcinogenic potential. Plant-derived phytoestrogens are attractive alternatives, but reports on their angiogenic activities often lack in-depth analysis and sometimes are controversial. Herein, we report a data-mining study with the existing literature, using IPA system to classify and characterize phytoestrogens based on their angiogenic properties and pharmacological consequences. We found that pro-angiogenic phytoestrogens functioned predominantly as cardiovascular protectors whereas anti-angiogenic phytoestrogens played a role in cancer prevention and therapy. This bidirectional regulation were shown to be target-selective and, for the most part, estrogen-receptor-dependent. The transactivation properties of ERα and ERβ by phytoestrogens were examined in the context of angiogenesis-related gene transcription. ERα and ERβ were shown to signal in opposite ways when complexed with the phytoestrogen for bidirectional regulation of angiogenesis. With ERα, phytoestrogen activated or inhibited transcription of some angiogenesis-related genes, resulting in the promotion of angiogenesis, whereas, with ERβ, phytoestrogen regulated transcription of angiogenesis-related genes, resulting in inhibition of angiogenesis. Therefore, the selectivity of phytoestrogen to ERα and ERβ may be critical in the balance of pro- or anti-angiogenesis process.
