Objective To investigate the clinical effects and safety of spiral stone basket assisted with FURL in the treatment of unilateral upper ureteral stones for diameter>1.0 cm. Methods 140 patients with unilateral upper ureteral stones for diameter>1.0 cm from January 2012 to December 2015 were randomly divided into control group (70 patients) with FURL used alone and observation group (70 patients) with spiral stone basket assisted application on the basis of control group;the perioperative clinical indicators, the lithotripsy success rate, the stone clearance rate, the stone removal rate and the postoperative complication incidence of both groups were compared. Results The operation time of observation group was signiifcantly longer than control group (P<0.05). There was no signiifcant difference in the blood loss volume in operation and hospitalization time between 2 groups (P>0.05). The lithotripsy success rate and the stone clearance rate of observation group was signiifcantly higher than control group (P<0.05). The stone removal rate of observation group was signiifcantly lower than control group (P<0.05). The postoperative complication incidence of observation group was no difference between 2 groups (P> 0.05). The total treatment expenses of observation group was signiifcantly fewer than control group (P<0.05). Conclusion Spiral stone basket assisted with FURL in the treatment of unilateral upper ureteral stones for diameter>1.0 cm can efifciently higher the stone removal effects, reduce the stone removal risk and not increase the postoperative complications incidence.

Objective:To evaluate the stability and bio-safety of warming moxibustion gel-unguentums( WMG) . Methods: With the commercially available package and at 40℃ ± 2℃, RH (75% ± 5%) for six months,the stability of WMG was inspected. Guinea pig skin sensitization test, rabbit skin irritation test and cell toxicity test were used to investigate the safety. Results:Compared to the results of 0 month, there was no difference in the sample character, containing paste percentage, adhesion, shape, weight difference and all theindices in TLC identification. Cell toxicity test showed that WMG had slight cytotoxicity. Guinea pig skin sensitization test and rabbit skin irritation test indicated that the grade of skin reaction was zero and the primary stimulus index of skin tissues was also zero. Conclusion:The quality of WMG is stable and the production preparation technology is feasible. Moreover, it is safe in transder-mal administration.

Doxorubicin(DOX)is a commonly administered chemotherapy drug for treating hematological malignancies and solid tumors;however,its clinical application is limited by significant cardiotoxicity.Cynaroside(Cyn)is a flavonoid glycoside distributed in honeysuckle,with confirmed potential biological functions in regulating inflammation,pyroptosis,and oxidative stress.Herein,the effects of Cyn were evaluated in a DOX-induced cardiotoxicity(DIC)mouse model,which was established by intraperitoneal injections of DOX(5 mg/kg)once a week for three weeks.The mice in the treatment group received dexrazoxane,MCC950,and Cyn every two days.Blood biochemistry,histopathology,immunohistochemistry,reverse transcription-quantitative polymerase chain reaction(RT-qPCR),and western blotting were conducted to investigate the cardioprotective effects and potential mechanisms of Cyn treatment.The results demonstrated the significant benefits of Cyn treatment in mitigating DIC;it could effectively alleviate oxidative stress to a certain extent,maintain the equilibrium of cell apoptosis,and enhance the cardiac function of mice.These effects were realized via regulating the transcription levels of pyroptosis-related genes,such as nucleotide-binding oligomerization domain-like receptor protein 3(NLRP3),caspase-1,and gasdermin D(GSDMD).Mechanistically,for DOX-induced myocardial injury,Cyn could significantly modulate the expression of pivotal genes,including adenosine monophosphate-activated protein kinase(AMPK),peroxisome proliferator-activated receptor γ coactivator-1α(PGC-1α),sirtuin 3(SIRT3),and nuclear factor erythroid 2-related factor 2(Nrf2).We attribute it to the mediation of AMPK/SIRT3/Nrf2 pathway,which plays a central role in preventing DOX-induced cardiomyocyte injury.In conclusion,the present study confirms the therapeutic potential of Cyn in DIC by regulating the AMPK/SIRT3/Nrf2 pathway.

On January 22, 2020, China National Center for Bioinformation (CNCB) released the 2019 Novel Coronavirus Resource (2019nCoVR), an open-access information resource for the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). 2019nCoVR features a comprehensive integra-tion of sequence and clinical information for all publicly available SARS-CoV-2 isolates, which are manually curated with value-added annotations and quality evaluated by an automated in-house pipeline. Of particular note, 2019nCoVR offers systematic analyses to generate a dynamic landscape of SARS-CoV-2 genomic variations at a global scale. It provides all identified variants and their detailed statistics for each virus isolate, and congregates the quality score, functional annotation,and population frequency for each variant. Spatiotemporal change for each variant can be visualized and historical viral haplotype network maps for the course of the outbreak are also generated based on all complete and high-quality genomes available. Moreover, 2019nCoVR provides a full collection of SARS-CoV-2 relevant literature on the coronavirus disease 2019 (COVID-19), including published papers from PubMed as well as preprints from services such as bioRxiv and medRxiv through Europe PMC. Furthermore, by linking with relevant databases in CNCB, 2019nCoVR offers data submission services for raw sequence reads and assembled genomes, and data sharing with NCBI. Collectively, SARS-CoV-2 is updated daily to collect the latest information on genome sequences, variants, hap-lotypes, and literature for a timely reflection, making 2019nCoVR a valuable resource for the global research community. 2019nCoVR is accessible at https://bigd.big.ac.cn/ncov/.

【Objective】 To determine the reference range of thromboelastogram(TEG) and establish a TEG feature for local population by measuring TEG parameters in healthy adults in Shenzhen comparing the difference between gender and age, and analyzing the reference data provided by reagent manufacturer. 【Methods】 A total of 916 healthy adults, aged between 19 to 59, who did their regular health checks in our hospital from September 2020 to August 2021 were selected. The TEG(from Lepu Medical Technology Co., Ltd.) was performed, and the clot reaction time(R), clot formation time(K), coagulation angle(α-Angle), maximum amplitude(MA), coagulation index(CI), fibrinolysis index LY30 and the estimated percent lysis (EPL) were analyzed. 【Results】 The reference ranges of TEG parameters, including R, K, α-Angle, MA, CI, LY30 and EPL, of 916 healthy adults from Shenzhen were 3.25~8.19 min, 0.66~3.18min, 47.70~76.56deg, 50.05~72.91mm, -4.3~3.4, 0~2.2% and 0~3%, respectively. The value of α-Angle, CI, K, LY30, MA and R didn’t all meet the given range provided by the manufacturer; some were exceeding and some inferior to. A total of 227 out of 916 individuals presented abnormal results, relative to the references, in at least one parameter, and 78 were diagnosed of abnormal coagulation based on the given reference range, with a specificity of 75.2%. 【Conclusion】 The reference range of TEG parameters of Shenzhen locals is significantly different from that provided by manufacturers. And it is imperative for local TEG laboratories to establish their own reference ranges according to age and gender groups based on local population characteristics.
