Objective To systematically evaluate the clinical efficacy of the prescriptions for softening hardness to dissipate mass combined with Levothyroxine Sodium in the treatment of postoperative thyroid cancer,and to provide evidence-based medical proof for clinical treatment of postoperative thyroid cancer.Methods Computer search was performed in the major domestic and oversea databases for the retrieval of clinical randomized controlled trials(RCTs)of prescriptions for softening hardness to dissipate mass combined with Levothyroxine Sodium for the treatment of postoperative thyroid cancer.After screening the literature according to the inclusion and exclusion criteria,the quality of the included literature was evaluated using the tools for analysis of the bias recommended by Cochrane Reviewer's Handbook and the modified JADAD rating scale,and meta-analysis was performed using RevMan 5.4 software.Results A total of 11 RCTs involving 749 patients were eventually included.The results of meta-analysis showed that compared with Levothyroxine Sodium alone,prescriptions for softening hardness to dissipate mass combined with Levothyroxine Sodium significantly enhanced the efficacy of postoperative patients with thyroid cancer(RR=1.30,95%CI[1.21,1.41],Z = 6.81,P＜0.000 01),and improved the thyroid functions parameters of serum thyroid stimulating hormone(TSH)(SMD=-1.75,95%CI[-2.38,-1.13],Z = 5.47,P＜0.000 01),thyroglobulin(TG)(SMD=-1.13,95%CI[-1.71,-0.55],Z = 3.81,P = 0.000 1),free triiodothyronine(FT3)(SMD=3.42,95%CI[0.73,6.10],Z = 2.50,P = 0.01),free thyroxine(FT4)(SMD=1.85,95%CI[0.05,3.66],Z = 2.02,P = 0.04),and thyroglobulin antibody(TgAb)(SMD=-0.63,95%CI[-1.11,-0.15],Z = 2.55,P = 0.01),increased Karnofsky Performance Status(KPS)scores(SMD= 2.19,95%CI[1.30,3.08],Z = 4.81,P＜0.000 01),shortened the time for the relief of clinical symptoms after thyroid cancer surgery(MD=-4.67,95%CI[-5.38,-3.96],Z = 12.87,P＜0.000 01),reduced the diameter of the largest thyroid nodule after thyroid cancer surgery(MD=-2.51,95%CI[-3.13,-1.89],Z = 7.94,P＜0.000 01),regulated the immune function indicators of T lymphocyte population CD3+(MD=8.68,95%CI[4.97,12.39],Z = 4.59,P＜0.000 01)and CD4+(MD=10.77,95%CI[5.46,16.08],Z = 3.97,P＜0.000 1)levels,and reduced the incidence of postoperative complications of thyroid cancer(RR=0.34,95%CI[0.18,0.65],Z = 3.26,P = 0.001).The differences were all statistically significant(P＜0.05).Conclusion prescriptions for softening hardness to dissipate mass combined with Levothyroxine Sodium can enhance the efficacy of postoperative patients with thyroid cancer.The combined therapy is superior to Levothyroxine Sodium alone in improving thyroid function indicators,KPS score,time for the relief of clinical symptoms,diameter of the largest thyroid nodule,immune function indicators,and the incidence of postoperative complications.However,due to the small amount of included trials and the fact that the prescriptions for softening hardness to dissipate mass vary in the composition,the conclusions of the analysis need to be confirmed by more high-quality,multi-center,large-sample clinically randomized controlled trials.

Paroxysmal nocturnal hemoglobinuria (PNH) is an acquired clonal hematopoietic stem cell disease caused by abnormal expression of glycosylphosphatidylinositol (GPI) on the cell membrane due to mutations in the phosphatidylinositol glycan class A(PIGA) gene. It is commonly characterized by intravascular hemolysis, repeated thrombosis, and bone marrow failure, as well as multiple systemic involvement symptoms such as renal dysfunction, pulmonary hypertension, swallowing difficulties, chest pain, abdominal pain, and erectile dysfunction. Due to the rarity of PNH and its strong heterogeneity in clinical manifestations, multidisciplinary collaboration is often required for diagnosis and treatment. Peking Union Medical College Hospital, relying on the rare disease diagnosis and treatment platform, has invited multidisciplinary clinical experts to form a unified opinion on the diagnosis and treatment of PNH, and formulated the Expert Consensus of Multidisciplinary Diagnosis and Treatment for Paroxysmal Nocturnal Hemoglobinuria (2024), with the hope of promoting the standardization of PNH diagnosis and treatment.

Refractory prolactinoma is the most common pituitary neuroendocrine tumor.Dopamine receptor agonists(DA)are the primary choice for drug treatment.Most patients with prolactinomas respond well to DA.However,a minority of prolactinomas patients still show resistance to DA.Although drug-resistant and refractory prolactinomas are rare in clinical practice,their treatment is extremely challenging.Even a combination of drug therapy,multiple surgeries,and radiotherapy may not yield satisfactory outcomes.Therefore,standardizing the diagnosis and treatment process and pathway for refractory prolactionmas and exploring more effective multidisciplinary collaborative treatment strategies are urgent problems to be solved.In the clinical management of refractory prolactinomas,it is often necessary to consider the patient's condition comprehensively,replace other types of DA,or consider surgery,radiotherapy,and immunotherapy,which requires multidisciplinary diagnosis and treatment.This review synthesizes the latest literature at home and abroad to systematically discuss the latest advances in drug therapy,surgery,and radiotherapy treatments for refractory prolactionmas,aiming to provide new ideas for basic research,clinical diagnosis and treatment.

OBJECTIVE: To investigate the mechanism of nucleolin (NCL) involved in lymphoma proliferation by regulating thymidine kinase 1 (TK1). METHODS: Twenty-three patients with diffuse large B-cell lymphoma (DLBCL) were selected and divided into initial treatment group (14 cases) and relapsed/refractory group (9 cases). Serum TK1 and C23 protein in peripheral blood mononuclear cells were detected. Cell models of CA46-NCL-KD (CA46-NCL-knockdown) and CA46-NCL-KNC (CA46-NCL-knockdown negative control) were established by lentivirus vector mediated transfection in Burkitt lymphoma cell line CA46. The half maximal inhibitory concentration (IC₅₀) of CA46-NCL-KD, CA46-NCL-KNC, and CA46 to adriamycin were detected by cell proliferation assay (MTS). The expression of NCL mRNA and protein in CA46-NCL-KD and CA46-NCL-KNC cells were dectected by Q-PCR and Western blot, respectively. The cell cycle of CA46-NCL-KD, CA46-NCL-KNC, and CA46 cells were detected by flow cytometry. The expression of TK1 protein in CA46-NCL-KD and CA46-NCL-KNC cells was detected by an enhanced chemiluminescence (ECL) dot blot assay. RESULTS: The level of serum TK1 in the initial treatment group was 0.43(0-30-1.01) pmol/L, which was lower than 10.56(2.19-14.99) pmol/L in the relapsed/refractory group (P<0-01), and the relative expression level of NCL protein in peripheral blood was also significantly lower. The IC₅₀ of CA46-C23-KD cells to adriamycin was (0.147±0.02) μg/ml, which was significantly lower than (0.301±0.04) μg/ml of CA46-C23-KNC cells and (0.338±0.05) μg/ml of CA46 cells (P<0.05). Compared with CA46-NCL-KNC cells, the expression of NCL mRNA and protein, TK1 protein decreased in CA46-NCL-KD cells, and the proportion of S phase and G₂/M phase also decreased, while G0/G1 phase increased in cell cycle. CONCLUSION The increased expression of NCL in DLBCL and CA46 cells indicates low sensitivity to drug. NCL may participate in regulation of lymphoma proliferation by affecting TK1 expression, thereby affecting the drug sensitivity.

Objective: To investigate the factors influencing total bilirubin elevation and its correlation with UGT1A1 gene polymorphism in the early postoperative period of transjugular intrahepatic portosystemic shunt (TIPS). Methods: 104 cases with portal hypertension and esophageal variceal hemorrhage (EVB) treated with elective TIPS treatment were selected as the study subjects and were divided into a bilirubin-elevated group and a normal bilirubin group according to the total bilirubin elevation level during the early postoperative period. Univariate analysis and logistic regression were used to analyze the factors influencing total bilirubin elevation in the early postoperative period. PCR amplification and first-generation sequencing technology were used to detect the polymorphic loci of the UGT1A1 gene promoter TATA box, enhancer c.-3279 T > G, c.211G > A, and c.686C > A. Logistic regression was used to analyze the correlation of four locus alleles and genotypes with elevated total bilirubin in the early postoperative period. Results: Among the 104 cases, 47 patients were in the bilirubin elevated group, including 35 males (74.5%) and 12 females (25.5%), aged (50.72 ± 12.56) years. There were 57 cases in the normal bilirubin group, including 42 males (73.7%) and 15 females (26.3%), aged (51.63 ± 11.10) years. There was no statistically significant difference in age (t = -0.391, P = 0.697) and gender (χ(2) = 0.008, P = 0.928) between the two groups of patients. Univariate analysis revealed that preoperative alanine transaminase (ALT) level (χ(2) = 5.954, P = 0.015), total bilirubin level (χ(2) = 16.638, P < 0.001), MELD score (χ(2) = 10.054, P = 0.018), Child-Pugh score (χ(2) = 6.844, P = 0.022), and postoperative portal vein branch development (χ(2) = 6.738, P = 0.034) were statistically significantly different between the two groups. Logistic regression analysis showed that preoperative ALT level, total bilirubin level, and portal vein branch development after TIPS were correlated with the elevated total bilirubin in the early postoperative period. The polymorphism of the c.211G > A locus of the UGT1A1 gene correlation had elevated total bilirubin in the early postoperative period of TIPS. The risk of elevated total bilirubin was increased in the population carrying allele A (P = 0.001, OR = 4.049) in the early postoperative period. Allelic polymorphisms in the TATA box promoter region and enhancer c.-3279 T > G and c.686C > A had no statistically significant difference between the bilirubin-elevated group and the normal bilirubin group. Conclusion: The preoperative ALT level, total bilirubin level, and portal vein branch development are correlated with the elevated total bilirubin in early postoperative patients. The polymorphisms of the UGT1A1 gene and enhancer c.211G > A are correlated with the occurrence of elevated total bilirubin in the early postoperative period of TIPS. Allele A carrier may have a higher risk of elevated total bilirubin in the early postoperative period.

ObjectiveTo explore the mechanism of Xueniao capsule in the treatment of acute pyelonephritis （APN） by network pharmacology and experimental verification. MethodThe effect of Xueniao capsule on APN was investigated based on the APN model in rats. The Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP）， Chemistryl Database， and SymMap were searched for the chemical components of Smilacis Chinae Rhizoma，Coicis Semen， and Trachycarpi Petiolus. The target information of the components was collected from PharmMapper and SwissTargetPrediction， and disease target information from Therapeutic Target Database （TTD）， DrugBank， DisGeNET， GeneCards， and Online Mendelian Inheritance in Man（OMIM）. The key genes of Xueniao capsule for APN underwent Gene Ontology（GO） and Kyoto Encyclopedia of Genes and Genomes（KEGG） pathway enrichment analyses by Metascap. Real-time quantitative polymerase chain reaction （PCR） and Western blot were employed to verify the prediction results. ResultCompared with the blank group and the sham operation group， the model group showed an increased ratio of the left kidney to the right kidney and organ index（P<0.05， P<0.01），up-regulated white blood cells （WBC），neutrophils （NEUT），monocytes （MONO）， and lymphocytes （LY）（P<0.05， P<0.01）， and elevated levels of nuclear factor-κB（NF-κB）， interleukin-6 （IL-6）， and tumor necrosis factor-α （TNF-α）（P<0.05， P<0.01）. Compared with the model group， the norfloxacin group， the low- and high-dose Xueniao capsule groups showed a decreased ratio of the left kidney to the right kidney and organ index（P<0.05， P<0.01）， dwindled levels of WBC， NEUT， MONO， and LY（P<0.05， P<0.01）， and reduced levels of NF-κB， IL-6， and TNF-α（P<0.05， P<0.01）. The medium-dose Xueniao capsule group showed a decreased ratio of the left kidney to the right kidney and organ index（P<0.05， P<0.01）， reduced levels of WBC， NEUT， MONO， and LY（P<0.05， P<0.01）， and dwindled levels of IL-6 and TNF-α（P<0.05， P<0.01）. Network pharmacological analysis revealed 17 active compounds from Smilacis Chinae Rhizoma， 18 active compounds from Coicis Semen， six active compounds from Trachycarpi Petiolus， and 39 key genes for the treatment of APN in Xueniao capsule. GO enrichment analysis demonstrated 704 biological processes， 22 cellular components， and 59 molecular functions. Sixty-two pathways were enriched in KEGG enrichment analysis. The experimental verification results showed that compared with the blank group， the model group showed increased mRNA expression of prostaglandin-endoperoxide synthase 2 （PTGS2）， mitogen-activated protein kinase 1 （MAPK1）/extracellular signal-regulated protein kinase 2 （ERK2），phosphoinositide 3 kinase （PI3K），protein kinase B2（Akt2），Janus kinase 2 （JAK2），and signal transducer and activator of transcription 3 （STAT3）and protein expression of PI3K， Akt2， JAK2， and STAT3 （P<0.05， P<0.01）. Compared with the model group， the low-dose Xueniao capsule group showed decreased mRNA expression of MAPK1， PI3K， JAK2， and STAT3 and protein expression of PI3K， JAK2， and STAT3 （P<0.05， P<0.01）. The medium-dose Xueniao capsule group showed decreased mRNA expression of MAPK1， PTGS2， PI3K， JAK2， and STAT3， and protein expression of PI3K， JAK2， and STAT3 （P<0.05， P<0.01）. The high-dose Xueniao capsule group showed reduced mRNA expression of PTGS2， MAPK1， PI3K， Akt2， JAK2， and STAT3 and protein expression of PI3K， Akt2， JAK2， and STAT3 （P<0.05， P<0.01）. ConclusionXueniao capsule has a certain curative effect on APN via multiple targets and multiple pathways. The mechanism may be related to the inhibition of the PI3K/Akt signaling pathway and the JAK2/STAT3 signaling pathway.

Chicoric acid， a hydroxycinnamic acid with the molecular formula C₂₂H₁₈O₁₂， is an important active ingredient in Taraxacum mongolicum， Echinacea purpurea， Cichorium intybus and other natural plants， and it helps plants protect themselves from insects and infection from viruses， bacteria， fungi， and nematodes. Modern pharmacological research suggests that chicoric acid has significant bioactivities such as anti-inflammatory， antioxidant， immune-regulating， antibacterial， antiviral and anti-tumor properties. The first reported bioactivity of chicoric acid is its inhibitory effect on human immunodeficiency virus （HIV）. With the development and application of molecular biology and related technologies， the inhibitory activities of chicoric acid on other viruses as well as its mechanism of action have been frequently reported. Another study indicates that chicoric acid has significant inhibitory effects on different pathogenic bacteria. This paper summarized the research progress on the antiviral and antibacterial effects of chicoric acid through a comprehensive review of relevant literature in China and abroad in the past 20 years. Studies have shown that chicoric acid has significant inhibitory activities against various viruses such as HIV， hepatitis B virus （HBV）， respiratory syncytial virus （RSV）， and herpes simplex virus （HSV）， as well as different pathogenic bacteria such as Staphylococcus aureus， Yersinia enterocolitica and Mycobacterium tuberculosis. This study is expected to provide references for in-depth research on chicoric acid against pathogenic microorganisms and antiviral and antibacterial study of traditional Chinese medicine.

Objective:To explore the feasibility of applying quantitative flow ratio(QFR) to assess the degree of coronary artery functional stenosis before surgery, and to guide coronary artery bypass grafting(CABG) revascularization strategy.Methods:The study prospectively included a total of 154 patients who were electively treated with CABG in the 11th ward of the Department of Cardiac Surgery of Beijing Anzhen Hospital from January 2019 to September 2020, and their coronary angiography visually showed stenosis of the coronary artery to perform QFR analysis to know the diseased blood vessels. For functional stenosis, the surgeon was blinded to the results of QFR analysis before surgery. Collect its baseline data, perioperative data and recent clinical outcomes for summary analysis.Results:One year later, the coronary artery CTA showed that the occlusion rate of functionally significant disease(QFR<0.8) was 5.5%, and that of non-functionally significant disease(QFR≥0.8) was 15.6%. There was no difference in angina class or repeat interventions between patients with or without occluded bypass grafts.Conclusion:According to QFR analysis, coronary arteries with functional non-significant disease have a higher risk of grafts failure than those with functionally significant disease. For coronary arteries with negative QFR lesions, the risk of occlusion of arterial grafts is higher than that of venous. However, this finding is not significantly related to clinical prognosis, because patients with patency or occlusion of the grafts in non-significant lesions have not found excessive angina pectoris or repeated coronary interventions. QFR-guided selection of coronary surgery strategies is safe and feasible.

Objective: To investigate the clinical value of the bipolar tweezers-clamp for the hepatic parenchymal transection in the resection of hepatocellular carcinoma. Methods: From January 2020 to January 2021,63 patients with the hepatocellular carcinoma for hepatectomy at Department of Hepatopancreatobiliary Surgery,Yuebei People's Hospital Affiliated to Shantou University Medical College were analyzed retrospectively.According to the different instruments used in the hepatic parenchymal transection,the patients were divided into bipolar tweezers-clamp group and ultrasonic scalpel group.There were 32 patients in bipolar tweezers-clamp group,with age of (55.5±10.5)years(range:37 to 78 years),including 22 males and 10 females,tumor size was (6.0±3.4)cm(range:2.4 to 13.4 cm). There were 6 patients with portal vein tumor thrombus and 5 patients with portal hypertension. There were 31 patients in ultrasonic scalpel group,with aged(57.8±10.1)years(range:37 to 79 years),including 27males and 4 females,tumor size was(7.9±5.1)cm(range: 2.4 to 21.3 cm),3 patients with portal vein tumor thrombus and 2 patients with portal hypertension. The preoperative baseline data,operation time,blood loss,postoperative liver function and the complications were compared between two groups using t test,χ² test and Fisher exact probabilityrespectively. Results: The operation was successfully completed in both groups.Compared with the ultrasonic scalpel group,the operation time was significantly shorter((219.3±76.4)minutes vs.(294.0±100.8)minutes,t=-3.322,P=0.002),the blood loss was less((250(475)ml vs. 500(1 050)ml,t=-2.307,P=0.026),the concentrate red blood cells transfusion volume was less(0.92(0.88)U vs. 2.32(4.00)U,Z=-1.987,P=0.047) in the bipolar tweezers-clamp group.The postoperative serum ALB level was higher in the bipolar tweezers-clamp group than that in the ultrasonic scalpel group((33.5±6.1)g/L vs. (29.5±4.2)g/L,t=3.226,P=0.020) on postoperative day 1;((35.7±4.5)g/L vs.(30.1±3.2)g/L,t=5.575,P<0.01) on postoperative day 3;((33.2±3.7)g/L vs. (31.0±4.4)g/L,t=3.020,P=0.004) on postoperative day 7. There was no significant difference in serum ALT,TBIL and PT level between the two groups(all P>0.05).No postoperative bile leakage occurred in both groups.The postoperative complications occurred in 8 cases(25.0%)in the bipolar tweezers-clamp group,including liver failure in one,and in 11 cases(35.5%)in the ultrasonic scalpel group,including liver failure in two(P>0.05). Conclusion: The bipolar tweezers-clamp is a safe and reliable method for the hepatic parenchymal transaction,which is quick and less bleeding during the hepatic resection.
