This article systematically analyzes the historical evolution of the name， origin， quality evaluation， harvesting， processing and other aspects of Picrorhizae Rhizoma by referring to the medical books， prescription books， and other documents of the past dynasties， combined with relevant modern research materials， in order to provide a basis for the development and utilization of famous classical formulas containing this medicinal herb. The research results indicate that Picrorhizae Rhizoma was first recorded in New Revised Materia Medica from the Tang dynasty. Throughout history， Huhuanglian has been used as its official name， and there are also aliases such as Gehu Luze， Jiahuanglian and Hulian. The main source of past dynasties is the the rhizomes of Picrorhiza kurrooa and P. scrophulariiflora. In ancient times， Picrorhizae Rhizoma was mainly imported by foreign traders via Guangzhou and other regions， and also produced in China， mainly in Xizang. In ancient times， it was harvested and dried in early August of the lunar calendar， while in modern times， it is mostly harvested from July to September， with the best quality being those with thick and crispy rhizomes without impurities， and bitter taste. Throughout history， Picrorhizae Rhizoma was collected， washed， sliced， and dried before being used as a raw material for medicine， it has a bitter and cold taste， mainly used to treat bone steaming， hot flashes， infantile chancre fever， and dysentery. There is no significant difference in taste and efficacy between ancient and modern times. Based on the research results， it is recommended that the rhizomes of P. scrophulariiflora in the 2020 edition of Chinese Pharmacopoeia， or the rhizomes of P. kurrooa， can be used in famous classical formulas containing this medicinal herb， which can be processed according to the processing requirements marked by the original formula. For those without clear processing requirements， the dried raw products are used as medicine.

Hyperkalemia is one of the common ion metabolism disorders in clinical practice. Hyperkalemia is defined as serum potassium higher than 5.0 mmol/L according to the guidelines at home and abroad. Acute severe hyperkalemia can cause serious consequences, such as flaccid paralysis, fatal arrhythmia, and even cardiac arrest. The use of renin-angiotensin- aldosterone system inhibitors, β-blockers and diuretics, low-sodium and high-potassium diets, and the presence of related comorbidities increase the occurrence of hyperkalemia. Hyperkalemia risk exist in all clinical departments, but there is a lack of a standardization in the management of multi- department cooperation in hospital. Therefore, a number of domestic nephrology and cardiology department experts have discussed a management model for multi-department cooperation in hyperkalemia, formulating the management standard on hospital evaluation, early warning, diagnosis and treatment, and process. This can promote each department to more effectively participate in nosocomial hyperkalemia diagnosis and treatment, as well as the long-term management of chronic hyperkalemia, improving the quality of hyperkalemia management in hospital.

Objectives:Present study analyzed the efficacy and safety of percutaneous coronary intervention(PCI)using the distal transradial access(dTRA)for patients with complex coronary lesions. Methods:A total of 10 033 patients with complex coronary artery lesions(type B2 and type C lesions)who underwent percutaneous coronary intervention(PCI)via dTRA or conventional transradial access(TRA)at Fuwai Hospital between June 2021 and May 2022 were included(9 625 patients in the TRA group and 408 patients in the dTRA group).After propensity score matching,391 patients were included in each group.Baseline data,PCI intraoperative data(including lesion characteristics,intervention success rate,etc.),and incidence of major bleeding related to the access were compared between the two groups before and after propensity score matching. Results:Before propensity score matching,the proportions of patients with hypertension,hyperlipidemia,family history of coronary heart disease,history of myocardial infarction,and history of coronary artery bypass grafting were significantly higher in the dTRA group than in the TRA group(all P<0.05).After propensity score matching,the baseline data of the two groups were similar(all P>0.05).Before propensity score matching,compared with the TRA group,patients in the dTRA group had a higher proportion of patients with type B2 lesions,while the proportions of patients with type C lesions and those using intravascular ultrasound(IVUS)were lower(all P<0.05).The proportion of patients with chronic complete occlusion was similar between the two groups(P>0.05).After propensity score matching,compared with the TRA group,patients in the dTRA group had a lower proportion using IVUS and had a higher percent of stent implantation(both P<0.05).There was no statistically significant difference between the two groups in terms of SYNTAX score,guide catheter size,target lesion distribution,proportion of patients using intra-aortic balloon counterpulsation,success rate of intervention procedures,and incidence of major bleeding events related to the access(all P>0.05). Conclusions:Compared with the conventional TRA,interventional treatment of complex lesions through dTRA is equally safe and effective for patients with complex coronary lesions.

Objective To evaluate the effect of water exchange method versus conventional methods including air insufflation and carbon dioxide insufflation method for the quality of colonoscopy.Methods We searched related randomized controlled trials published up to October 2022 from PubMed,Web of Science,the Cochrane Library,SinoMed databases,CNKI,Wanfang data.Two reviewers independently searched the literatures based on standards to extract the data and evaluate the quality.Meta-analysis was conducted by RevMan 5.4.1.Results 23 studies involving 10654 patients were included.Although cecal intubation time was prolonged in water exchange(MD=1.81,95％CI:1.28～2.35,P=0.000),but water exchange had higher adenoma detection rate(ADR)(O(R)=1.40,95％CI:1.26～1.55,P=0.000),cecal intubation rate(O(R)=1.62,95％CI:1.24～2.10,P=0.000)and scores of bowel preparation quality(MD=0.61,95％CI:0.42～0.79,P=0.000)compared with conventional colonoscopy.In addition,WE had significantly lower pain sores(MD=-1.07,95％CI:-1.39～-0.76,P=0.000),number of abdominal compression(O(R)=0.42,95％CI:0.29～0.60,P=0.000)and number of position change(O(R)=0.59,95％CI:0.42～0.82,P=0.002)than conventional colonoscopy.Conclusion Although water exchange colonoscopy prolongs cecal intubation time,but it can significantly increase ADR,cecal intubation rate and scores of bowel preparation quality.Beyond that,water exchange reduces patient pain,the proportion of abdominal compression and position change.Water exchange is a better choice for high-quality colonoscopy.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Purpose: This study aimed to investigate whether nighttime elective surgery influenced the short-term outcomes and prognosis of hepatocellular carcinoma (HCC) patients. Methods: The 1,339 HCC patients who underwent hepatectomy were divided into the daytime surgery group (8 a.m.–6 p.m., n = 1,105) and the nighttime surgery group (after 6 p.m., n = 234) based on the start time of surgery. The 1:2 propensity score matching (PSM) analysis was used to control confounding factors. The short-term outcomes of HCC patients in the 2 groups were compared before and after PSM. Factors associated with major complications (Clavien-Dindo grade, ≥III) and textbook oncologic outcomes (TOO) were separately identified by multivariable logistic regression based on variables screened via least absolute shrinkage and selection operator (LASSO). The Kaplan-Meier method was used to analyze overall survival (OS) and recurrence-free survival (RFS). Results: TOO was achieved after surgery in 897 HCC patients. HCC patients in the nighttime surgery group had a higher body mass index (P = 0.010). After 1:2 PSM, the baseline characteristics of patients between the 2 groups were similar. Short-term outcomes in HCC patients were comparable both before and after PSM (all Ps > 0.05), as were TOO in the 2 groups before (P = 0.673) and after PSM (P = 0.333). In our LASSO-logistic regression, nighttime surgery was not an independent factor associated with major complications or TOO. Both groups also had similar OS (P = 0.950) and RFS (P = 0.740) after PSM. Conclusion Our study revealed the safety of nighttime elective hepatectomy for HCC patients.

Indolylarylsulfones (IASs) are classical HIV-1 non-nucleoside reverse transcriptase inhibitors (NNRTIs) with a unique scaffold and possess potent antiviral activity. To address the high cytotoxicity and improve safety profiles of IASs, we introduced various sulfonamide groups linked by alkyl diamine chain to explore the entrance channel of non-nucleoside inhibitors binding pocket. 48 compounds were designed and synthesized to evaluate their anti-HIV-1 activities and reverse transcriptase inhibition activities. Especially, compound R₁₀L₄ was endowed with significant inhibitory activity towards wild-type HIV-1 (EC_50(WT) = 0.007 μmol/L, SI = 30,930) as well as a panel of single-mutant strains exemplified by L100I (EC₅₀ = 0.017 μmol/L, SI = 13,055), E138K (EC₅₀ = 0.017 μmol/L, SI = 13,123) and Y181C (EC₅₀ = 0.045 μmol/L, SI = 4753) which were superior to Nevirapine and Etravirine. Notably, R₁₀L₄ was characterized with significantly reduced cytotoxicity (CC₅₀ = 216.51 μmol/L) and showed no remarkable in vivo toxic effects (acute and subacute toxicity). Moreover, the computer-based docking study was also employed to characterize the binding mode between R₁₀L₄ and HIV-1 RT. Additionally, R₁₀L₄ presented an acceptable pharmacokinetic profile. Collectively, these results deliver precious insights for next optimization and indicate that the sulfonamide IAS derivatives are promising NNRTIs for further development.

Background:Complete colonoscopy is key to the diagnosis and treatment of colorectal disease,its role in reducing the morbidity and mortality of colorectal cancer is well known.Nonetheless,there are numerous factors,not just from the endoscopist's perspective but also from the patient's,that can potentially increase the difficulty of completing a colonoscopy.Aims:To identify patient-related factors that influenced the difficulty of a colonoscopy.Methods:Through two rounds of expert consultation,the factors that might affect the difficulty of colonoscopy were selected.A total of 1621 consecutive painless colonoscopies from Jan.2021 to Jan.2022 at the endoscopy center of The Affiliated Wuxi People's Hospital of Nanjing Medical University were evaluated in a retrospective manner.Factors including demographic data,cecal insertion time,adenoma detection rate and so on were recorded.These factors were analyzed to determine their association with difficulty by using Logistic regression model.Results:A total of 29 patient-related factors affecting the difficulty of colonoscopy were selected.Through retrospective analysis,the mean age of 1621 cases was(47.45±13.27)years,of which 45.8%were male and the mean body mass index was(23.32±3.11)kg/m2.Logistic regression analysis revealed that age≥60 years(OR=2.890,95%CI:1.957-4.269,P<0.001),female gender(OR=0.324,95%CI:0.217-0.484,P<0.001),history of gynecological surgery(OR=14.895,95%CI:9.741-22.776,P<0.001),constipation for 20-30 years(OR= 1.412,95%CI:0.925-2.156,P=0.010)were independent risk factors for difficult colonoscopy.Conclusions:This retrospective study identified several patient-related factors that influence the technical difficulty of colonoscopy.These findings had implications for practice and teaching of colonoscopy.

Objective:To investigate the effects of TRIB3 activation of Wnt/β-catenin signaling pathway on the growth and pro-liferation of laryngeal carcinoma TU686 cells in vitro and expression of peripheral immunosuppressive molecules in transplanted mice.Methods:Protein and RNA expressions of TRIB3 were detected in vitro cells(human immortalized epidermal cell line HaCat and laryngeal carcinoma cell line TU686)and tissues(laryngeal carcinoma and adjacent tissues),respectively.Laryngeal carcinoma TU686 cells were cultured in vitro and divided into negative control group(NC group)and TRIB3 knockdown group(sh-TRIB3 group),total protein and RNA of cells were extracted to verify the expression level of TRIB3 in two groups.After successful verifica-tion,proliferation ability of TU686 cells was detected by CCK-8,colony cloning and flow cytometry.Protein expression levels of Wnt,Cyclin-D1,C-myc,β-catenin and p-β-catenin in two groups were detected by Western blot.Correlation analysis verified the correla-tion between TRIB3 and Wnt,Cyclin-D1,C-myc,β-catenin,p-β-catenin protein expressions.TRIB3-low expressing nude mouse transplanted tumor model(TRIB3 sgRNA group)was constructed by knockdown the TRIB3 core plasmid,and a parallel control group(Control sgRNA group)was set up,tumor growth volume and weight were observed,and serum immunosuppressive molecules expres-sions was determined by ELISA.Results:Compared with HaCat cells and normal paracarcinoma tissues,TRIB3 was highly expressed in TU686 cells and laryngeal carcinoma tissues.Compared with negative control group,proliferation ability of TU686 cells was signifi-cantly inhibited after TRIB3 knockdown,and cell growth was blocked in G1/S phase.Expressions of Wnt,Cyclin-D1,C-myc andβ-catenin protein in Wnt/β-catenin signaling pathway were decreased significantly,while expression of p-β-catenin was increased significantly.TRIB3 was significantly correlated with protein expression levels of Wnt,Cyclin-D1,β-catenin and p-β-catenin.The in vivo results showed that compared with Control sgRNA group,tumor growth volume and weight of mice in TRIB3 sgRNA group were significantly decreased,and expressions of serum immunosuppressive molecules IL-4,IL-6,IL-10,TGF-β and PGE2 were signifi-cantly decreased.Conclusion:TRIB3 is highly expressed in TU686 cells,and TRIB3 can inhibit growth and proliferation of TU686 cells and transplanted tumors by activating Wnt/β-catenin-related signaling pathways,and reverse tumor immunosuppressive microen-vironment,suggesting that TRIB3 may be an effective target for laryngeal cancer.
