Tripterygium wilfordii multiglucoside,the primary active constituent of the Chinese materia medica of Tripterygium wilfordii,has anti-inflammatory and immune-regulation properties and is widely used to treat kidney and rheumatic and immunological diseases.However,the potential adverse effects of Tripterygium wilfordii multiglucoside on pediatric gonadal development have limited its clinical application in pediatrics.According to the traditional Chinese medicine theory,the reproductive toxicity of Tripterygium wilfordii is closely associated with deficiency in kidney essence and tian gui disorder.Based on the"kidney essence-tian gui"theory,this study elucidates the transformation of"kidney essence to tian gui"through the qi transformation of"original noumenon to supreme ultimate,"which is synergistically regulated by the accumulation of kidney qi,consolidation of spleen qi,and conveyance and dispersion of liver qi.It is channeled through the interconnected pathways of the thoroughfare channel,conception channel,and governor channel.The physiological process of"kidney essence to tian gui"is damaged by the bitter,cold,and toxicity of Tripterygium wilfordii,leading to kidney asthenia,spleen deficiency,liver depression,and meridian stagnation,causing tian gui dysregulation.Therefore,this study offers traditional Chinese medicine prevention and treatment strategies for pediatric medication safety,including nourishing the kidney essence to replenish the tian gui source,enhancing the middle jiao to strengthen the tian gui guard,regulating liver qi to promote the operation of tian gui,and unblocking the thoroughfare channel,conception channel,and governor channel to ensure the unobstructed pathway of tian gui.

Guided by the theory of "kidney generates marrow"， the study elaborates the viewpoint that the route of Yin Heel Channel （阴跷脉） is consistent with the "kidney-marrow-brain" axis from the perspective of the circulation of the meridians and the relationship between the zang-fu organs. Accordingly， it is believed that disease of Yin Heel Channel and dysfunction of the "kidney-marrow-brain" axis are the core pathogenesis of children enuresis， and it is elaborated from the following three major aspects， firstly， insufficient kidney essence， dysfunction of the "kidney-marrow-brain" axis， secondly， disease of Yin Heel Channel and deficiency and cold in lower jiao， and thirdly， disease of Yin Heel Channel and loss of nourishment of Chong Vessel. It is proposed to use the mode of "firstly needle， secondly moxibustion， and lastly consolidation" to treat children enuresis. Needle is to adjust yin and yang， warm yang and tonify kidney， and wake up the brain and open the orifices. The acupoints in Yin Heel Channel such as Zhaohai （KI 6）， Jiaoxin （KI 8） and confluence points of the eight extraordinary vessels such as Waiguan （TE 5）， Zulinqi （GB 41） are used， together with Baihui （GV 20）， Yintang （EX-HN 3）， Guanyuan （CV 4）， Qixue （KI 13）， Dazhong （KI 4）. Moxibustion is to reinforce healthy qi and warm yang， bank up the root and consolidate the original qi by moxibustion at Shenque （CV 8）， Mingmen （GV 4）， and Xuanshu （GV 5）. Consolidation is to use acupoints application to consolidate the therapeutic effect， and Guanyuan （CV 4） & Pangguangshu （BL 28）， Qihai （CV 6） & Zhishi （BL 52）， and Shenque （CV 8） & Ciliao （BL 32） are commonly used as the three groups of acupoints to warm the kidney and stop collapse， regulate and tonify the qi and blood.

Pien Tze Huang(PZH),a class-1 nationally protected traditional Chinese medicine(TCM),has been used to treat liver diseases such as hepatitis;however,the effect of PZH on the progression of sepsis is un-known.Here,we reported that PZH attenuated lipopolysaccharide(LPS)-induced sepsis in mice and reduced LPS-induced production of proinflammatory cytokines in macrophages by inhibiting the acti-vation of mitogen-activated protein kinase(MAPK)and nuclear factor-kappa B(NF-κB)signalling.Mechanistically,PZH stimulated signal transducer and activator of transcription 3(STAT3)phosphory-lation to induce the expression of A20,which could inhibit the activation of NF-κB and MAPK signalling.Knockdown of the bile acid(BA)receptor G protein-coupled bile acid receptor 1(TGR5)in macrophages abolished the effects of PZH on STAT3 phosphorylation and A20 induction,as well as the LPS-induced inflammatory response,suggesting that BAs in PZH may mediate its anti-inflammatory effects by acti-vating TGR5.Consistently,deprivation of BAs in PZH by cholestyramine resin reduced the effects of PZH on the expression of phosphorylated-STAT3 and A20,the activation of NF-κB and MAPK signalling,and the production of proinflammatory cytokines,whereas the addition of BAs to cholestyramine resin-treated PZH partially restored the inhibitory effects on the production of proinflammatory cytokines.Overall,our study identifies BAs as the effective components in PZH that activate TGR5-STAT3-A20 signalling to ameliorate LPS-induced sepsis.

Objective To investigate the gross alpha and gross beta radioactivity levels in drinking water around Shidao Bay Nuclear Power Plant before its operation. Methods Ten sampling sites were set up within 30 km of Shidao Bay Nuclear Power Plant. From 2018 to 2021, samples were collected during the dry season and wet season each year and were tested in a laboratory according to Standard examination methods for drinking water—radiological parameters (GB/T 5750.13—2006). Results From 2018 to 2021, the gross alpha radioactivity in drinking water within 30 km of Shidao Bay Nuclear Power Plant was within the range of about 0.004-0.420 Bq/L, which does not exceed the guided gross alpha radioactivity specified in the National Standard; from 2018 to 2021, the gross beta radioactivity level was about 0.008-1.050 Bq/L. In 2018, the gross beta radioactivity at the sampling site 4.7 km from the Nuclear Power Plant exceeded the guided level specified in the National Standards for Drinking Water Quality (GB 5749—2006), but it fell within the guided level in a repeat laboratory test after deducting the effect of ⁴⁰K on the gross beta radioactivity. Conclusion After deducting the effect of ⁴⁰K on the gross beta radioactivity, the gross alpha and gross beta radioactivity levels in drinking water within 30 km of Shidao Bay Nuclear Power Plant are within the guided levels specified in the National Standards.

Objective To analyze the radionuclide levels in food and the committed effective dose due to food intake in residents around the Shidaowan Nuclear Power Plant (SNPP). Methods Daily food samples were collected within 30 km radius around the nuclear power plant in 2019—2022. The radioactivity levels before and after the operation of SNPP were determined. The data were combined with the dietary consumption of residents in Shandong province, China to estimate the committed effective dose. Results The radionuclides ²³⁸U, ²³²Th, ²²⁶Ra, and ⁴⁰K in food were at normal background levels, and the average radioactivity was (0.062 ± 0.004), (0.121 ± 0.007), (0.162 ± 0.010), and (92.4 ± 5.5) Bq/kg fresh weight. Trace ¹³⁷Cs and ⁹⁰Sr were detected in some food samples and the average radioactivity was (0.047 ± 0.003) and (0.193 ± 0.200) Bq/kg fresh weight. The levels of radionuclides did not increase after the operation of SNPP compared with that before operation. The estimated committed effective dose in residents due to food intake was 0.205 mSv. Conclusion The radioactivity of food in the area around SNPP shows no difference before and after operation, and the dose burden is low in local residents.

Chest trauma is one of the most common injuries. Venous thromboembolism (VTE) as a common complication of chest trauma seriously affects the quality of patients′ life and even leads to death. Although there are some consensus and guidelines on the prevention and treatment of VTE at home and abroad, the current literatures lack specificity considering the diagnosis, treatment and prevention of VTE in patients with chest trauma have their own characteristics, especially for those with blunt trauma. Accordingly, China Chest Injury Research Society and editorial board of Chinese Journal of Traumatology organized relevant domestic experts to jointly formulate the Chinese expert consensus on the diagnosis, treatment and prevention of chest trauma venous thromboembolism associated with chest trauma (2022 version). This consensus provides expert recommendations of different levels as academic guidance in terms of the characteristics, clinical manifestations, risk assessment, diagnosis, treatment, and prevention of chest trauma-related VTE, so as to offer a reference for clinical application.
