Research progress on regulation of glucocorticoids on immune cells / 中国免疫学杂志

The immune system is the defender of human health,whose dysregulation is the source of various diseases.Re-duced immune defense and immune surveillance capabilities lead to difficulties in removing pathogens and malignant cells,thus increasing morbidity and mortality risk.Stress is a major factor in the decline of the immune system.In past studies,it has been demon-strated both in animal and humans that stress increases the levels of neuroendocrine hormones in the body,particularly glucocorticoids and catecholamines.Through the action of these stress hormones,stress has a number of detrimental effects on immune function,and this review combs through the progress of research on the regulation of immune cells by glucocorticoids.

The Clinical Application Value of Modified Laparoscopic Radical Surgery with-out Uterine Manipulator in Early Cervical Cancer / 实用妇产科杂志

Objective:To explore the clinical value of modified laparoscopic radical surgery without uterine ma-nipulator in the treatment of early cervical cancer.Methods:A retrospective analysis was conducted on the clinical data of 105 patients with early cervical cancer(stages ⅠB1,ⅠB2,ⅡA1)who underwent radical resection of cer-vical cancer in West China Second University Hospital,Sichuan University from January 2019 to January 2020.According to the operation methods,the patients were divided into uterine lifter-free group(35 cases),uterine lifter group(35 cases)and laparotomy group(35 cases).The operation duration,intraoperative blood loss,number of resected lymph nodes,postoperative anal exhaust time,drainage tube placement time,hospitalization time,inci-dence of surgical complications,recurrence rate and mortality rate were compared among the three groups.Re-sults:There was no statistically significant difference in the number of lymph node resection,the postoperative anal exhaust time,drainage tube placement time and hospitalization time among the three groups(P>0.05).Comparison between two groups showed that the operation time of the group without uterine lifting was longer than that of the laparotomy group,and the intraoperative bleeding volume and the Postoperative anal exhaust time of the laparotomy group were more than those of the other two groups,and the differences were statistically signif-icant(P<0.05).There were 18 cases of surgical complications in the three groups.The incidence rate of uterine lifter-free group,laparotomy group and uterine lifter group was 11.4%,20.0%and 20.0%,respectively,with no statistically significant difference(P>0.05).There were 8 patients with recurrence 2 years after operation,the re-currence rates of the uterine lifter-free group,the laparotomy group and the uterine lifter group were 0,5.7%and 17.1%,respectively,the difference was statistically significant(P<0.05).The recurrence rate of the group with-out uterine lifting was significantly lower than that of the uterine lifting group(P<0.05).There were0 death in the non-lifting group,0 in the laparotomy group,and 1 case in the uterine lifting device group within 2 years after oper-ation,the difference was no statistically significant(P>0.05).Conclusions:The modified laparoscopic radical re-section without uterine lifter can reduce the risk of tumor recurrence in laparoscopic radical resection with uterine lifter,which is equivalent to the treatment effect of open surgery,and does not increase the risk of surgical compli-cations.It has clinical application value.

ObjectiveTo screen the differential markers by analyzing volatile components in Dalbergia odorifera and its counterfeits， in order to provide reference for authentication of D. odorifera. MethodThe volatile components in D. odorifera and its counterfeits were detected by headspace gas chromatography-mass spectrometry（HS-GC-MS）， and the GC conditions were heated by procedure（the initial temperature of the column was 50 ℃， the retention time was 1 min， and then the temperature was raised to 300 ℃ at 10 ℃ for 10 min）， the carrier gas was helium， and the flow rate was 1.0 mL·min-1， the split ratio was 10∶1， and the injection volume was 1 mL. The MS conditions used electron bombardment ionization（EI） with the scanning range of m/z 35-550. The compound species were identified by database matching， the relative content of each component was calculated by the peak area normalization method， and principal component analysis（PCA）， orthogonal partial least squares-discrimination analysis（OPLS-DA） and cluster analysis were performed on the detection results by SIMCA 14.1 software， and the differential components of D. odorifera and its counterfeits were screened out according to the variable importance in the projection（VIP） value>2 and P<0.05. ResultA total of 26， 17， 8， 22， 24 and 7 volatile components were identified from D. odorifera， D. bariensis， D. latifolia， D. benthamii， D. pinnata and D. cochinchinensis， respectively. Among them， there were 11 unique volatile components of D. odorifera， 6 unique volatile components of D. bariensis， 3 unique volatile components of D. latifolia， 6 unique volatile components of D. benthamii， 8 unique volatile components of D. pinnata， 4 unique volatile components of D. cochinchinensis. The PCA results showed that， except for D. latifolia and D. cochinchinensis， which could not be clearly distinguished， D. odorifera and other counterfeits could be distributed in a certain area， respectively. The OPLS-DA results showed that D. odorifera and its five counterfeits were clustered into one group each， indicating significant differences in volatile components between D. odorifera and its counterfeits. Finally， a total of 31 differential markers of volatile components between D. odoriferae and its counterfeits were screened. ConclusionHS-GC-MS combined with SIMCA 14.1 software can systematically elucidate the volatile differential components between D. odorifera and its counterfeits， which is suitable for rapid identification of them.

ObjectiveTo analyze the migrating components absorbed into blood of the aqueous extract of Euphorbia helioscopia， and to explore the pharmacodynamic material basis of the aqueous extract of E. helioscopia against chronic obstructive pulmonary disease（COPD）. MethodUltra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry（UPLC-Q-TOF-MS/MS） was used to detecte the migrating components absorbed into blood of rats after intragastric administration of aqueous extract of E. helioscopia. An Agilent RRHD SB-C18 column（3 mm×100 mm， 1.8 μm） was used with 0.1% formic acid aqueous solution（A）-acetonitrile（B） as the mobile phase for gradient elution（0-15 min， 5%-30%B； 15-20 min， 30%-50%B； 20-30 min， 50%-95%B； 30-35 min， 95%-5%B）， and the detection wavelength of 190-800 nm， column temperature of 40 ℃， flow rate of 0.3 mL∙min-1 and injection volume of 4 μL. The electrospray ionization（ESI） was used in positive and negative ion modes， and the detection range was m/z 50-1 250. Network pharmacology was used to screen out the key components and the key targets of COPD through the interaction analysis. Metascape database was used to predict the molecular function， biological process， cellular composition and signal pathways mainly involved in the anti-COPD effect of E. helioscopia. Molecular docking technique was used to determine the affinity of key targets with key components. ResultA total of 29 migrating components absorbed into blood of rats were identified after intragastric administration of aqueous extract of E. helioscopia， 9 of which were prototype components and 20 were metabolites. Network pharmacological analysis showed that luteolin， quercetin， apigenin， naringenin and helioscopinolide C were the key components of E. helioscopia against COPD， and vascular endothelial growth factor A（VEGFA）， albumin（ALB）， protein kinase B1（Akt1）， tumor necrosis factor（TNF） and interleukin-6（IL-6） were the key targets. Molecular docking results showed that one diterpene lactone（helioscopinolide C） and three flavonoids（naringenin， luteolin， apigenin） in the migrating components absorbed into blood all had strong binding activity to the key targets of E. helioscopia against COPD. ConclusionNaringenin， helioscopinolide C， luteolin and apigenin may be the main anti-COPD active substances of E. helioscopia.

Analysis of influencing factors for underdiagnosis of high-grade squamous intraepithelial lesion of the uterine cervix and cervical cancer by colposcopy / 肿瘤研究与临床

Objective:To investigate the influencing factors for underdiagnosis of high-grade squamous intraepithelial lesion (HSIL) of the uterine cervix and cervical cancer by colposcopy.Methods:The clinical data of 957 patients who underwent colposcopy and were diagnosed as HSIL or cervical cancer by histopathology at the Second Hospital of Shanxi Medical University from January 2017 to June 2022 were retrospectively analyzed, and logistic regression was used to analyze the influencing factors for underdiagnosis of HSIL and cervical cancer by colposcopy.Results:The results of univariate analysis showed that the underdiagnosis of HSIL and cervical cancer by colposcopy was related to whether or not menopause was present, whether or not there was coitus bleeding, whether or not there was irregular bleeding, liquid-based thin-layer cytology test (TCT) results, the morphology of the uterine cervix, the results of acetowhitening test, the results of iodine test, whether or not there was cuffed crypt (gland) openings, whether or not there was mosaicism, whether or not there was punctate vessels, whether or not the transformed zone was completely visible, the type of transformed zone, and whether or not the lesions involved the glands (all P < 0.05), but the underdiagnosis didn't related to whether or not there was human papillomavirus (HPV) infection, whether or not there was high-risk HPV multiple infections and the results of endocervical curettage (all P > 0.05). The results of multivariate logistic regression analysis showed that irregular bleeding ( OR = 4.279, 95% CI 2.170-8.441, P < 0.001), atypical squamous cells of uncertain significance (ASC-US) by TCT ( OR = 0.415, 95% CI 0.226-0.761, P = 0.004), atypical squamous cells, cannot exclud high-grade squamous intraepithelial lesion (ASC-H)/HSIL by TCT ( OR = 0.389, 95% CI 0.206-0.735, P = 0.004), thick acetowhite epithelium by acetowhitening test ( OR = 0.015, 95% CI 0.004-0.055, P < 0.001), and punctate vessels ( OR = 0.327, 95% CI 0.173-0.616, P = 0.001) were independent influencing factors for underdiagnosis of HSIL and cervical cancer by colposcopy. Conclusions:A history of irregular bleeding is a risk factor for underdiagnosis of HSIL of the uterine cervix and cervical cancer by colposcopy, while TCT results of ASC-US, ASC-H/HSIL and colposcopic visualization of thick acetowhite epithelium and punctate vessels could reduce the risk of underdiagnosis

Potential therapeutic effects and applications of Eucommiae Folium in secondary hypertension / 药物分析学报

Eucommiae Folium(EF),a traditional Chinese medicine,has been used to treat secondary hypertension,including renal hypertension and salt-sensitive hypertension,as well as hypertension caused by thoracic aortic endothelial dysfunction,a high-fat diet,and oxidized low-density lipoprotein.The antihyperten-sive components of EF are divided into four categories:flavonoids,iridoids,lignans,and phenyl-propanoids,such as chlorogenic acid,geniposide acid and pinoresinol diglucoside.EF regulates the occurrence and development of hypertension by regulating biological processes,such as inhibiting inflammation,regulating the nitric oxide synthase pathway,reducing oxidative stress levels,regulating endothelial vasoactive factors,and lowering blood pressure.However,its molecular antihypertensive mechanisms are still unclear and require further investigation.In this review,by consulting the relevant literature on the antihypertensive effects of EF and using network pharmacology,we summarized the active ingredients and pharmacological mechanisms of EF in the treatment of hypertension to clarify how EF is associated with secondary hypertension,the related components,and underlying mechanisms.The results of the network pharmacology analysis indicated that EF treats hypertension through a multi-component,multi-target and multi-pathway mechanism.In particular,we discussed the role of EF tar-gets in the treatment of hypertension,including epithelial sodium channel,heat shock protein70,rho-associated protein kinase 1,catalase,and superoxide dismutase.The relevant signal transduction path-ways,the ras homolog family member A(RhoA)/Rho-associated protein kinase(ROCK)and nicotinamide adenine dinucleotide phosphate(NADPH)oxidase/eNOS/NO/Ca2+pathways,are also discussed.

Comparison of five-year survival status of patients with liver cirrhosis and esophagogastric varices bleeding treated by transjugular intrahepatic portosystemic shunt and drug combined with endoscopic treatment / 中华消化杂志

Objective:To investigate the clinical efficacy and prognosis of transjugular intrahepatic portosystemic shunt (TIPS) and drug combined with endoscopic treatment in patients with liver cirrhosis and esophagogastric variceal bleeding (EGVB).Methods:From January 2012 to December 2013, at the First Affiliated Hospital of Xi′an Jiaotong University, the data of 147 patients with liver cirrhosis and EGVB undergoing TIPS or drug combined with endoscopic treatment were retrospectively collected, with 87 cases in TIPS treatment group and 60 in drug combined with endoscopic treatment group.The 5 years follow-up data were analyzed, and the overall survival rates, rebleeding-free survival rates and hepatic encephalopathy-free survival rates at 6 weeks, 1 year, 2 years and 5 years after treatment of two groups were compared. Independent sample t test, Mann-Whitney U test, chi-square test, Fisher exact test, Z test, log-rank test and trend test were used for statistical analysis. Results:There were no significant differences in age, gender, etiology, Child-Pugh classification, initial liver function, coagulation function, liver ascites, previous history of hepatic encephalopathy, blood pressure and preoperative blood transfusion history between the TIPS treatment group and combination of drugs and endoscopy treatment group (all P>0.05). Forty-one patients died within 5 years, of which 20 (48.8%) died of rebleeding and 6 (14.6%) died of hepatic encephalopathy. There were no significant differences in 6-week, 1-year and 2-year overall survival rates between the TIPS group and drug combined with endoscopic treatment group (all P>0.05), however the 5-year overall survival rate of the TIPS treatment group was higher than that of the drug combined with endoscopic treatment group (78.4% vs. 63.2%), and the difference was statistically significant ( Z=2.06, P=0.048). The 6-week, 1-year, 2-year, 5-year rebleeding-free survival rates of the TIPS group were 97.7%, 96.5%, 88.9% and 70.9%, respectively, which were all higher than those of the drug combined with endoscopic treatment group (86.7%, 53.3%, 43.3% and 27.1%), and the differences were statistically significant ( Z=2.35, 6.39, 6.26 and 4.80, all P<0.05). There were no significant differences in hepatic encephalopathy-free survival rates at 6 weeks, 1 year and 2 years after treatment between the TIPS group and drug combined with endoscopic treatment group (all P>0.05), however the 5-year hepatic encephalopathy-free survival rate of the TIPS treatment group was lower than that of the drug combined with endoscopic treatment group (67.7% vs. 86.7%), and the difference was statistically significant ( Z=2.28, P=0.030). The lower the Child-Pugh classification, the higher the cumulative 5-year survival rate ( χ2=6.75, P<0.01). There was no statistically significant difference in the 5-year overall survival rate in patients with the same Child-Pugh classification between the TIPS group and the drug combined with endoscopic treatment group (all P>0.05). Conclusions:The efficacy of TIPS is better than that of the drug combined with endoscopic treatment in treating EGVB. Even the long-term risk of hepatic encephalopathy of TIPS is higher, the short-term, middle-term and long-term rebleeding rate are decreased. Patients with Child-Pugh grade C do not need to avoid TIPS when choosing the treatment, the earlier the TIPS used, the better survival benefit will be obtained.

Influence of cardiopulmonary bypass on postoperative brain cognitive function of children with congenital heart disease / 中华实用儿科临床杂志

Congenital heart disease (CHD) is the most common congenital malformation disease in infants.With the rapid development of clinical treatment, the survival rate of children with CHD increased significantly.However, postoperative complications in children with CHD, including heart failure, heart arrythmia, pulmonary hypertension and brain cognitive dysfunction, are another challenge, among which, brain cognitive dysfunction has been gradually recognized and valued by scholars.At present, the effect of cardiopulmonary bypass on brain cognitive function of children with CHD has been studied by a variety of research methods, including molecular biological technique, magnetic resonance imaging technique, optical imaging technology, brain electrical activity monitoring technology and nervous development scale.Varying degrees of brain cognitive dysfunction will occur in children with CHD after heart surgery, which is closely associated with many factors such as systemic inflammatory response related to cardiopulmonary bypass, cerebral ischemia-reperfustion injury, the duration of cardiopulmonary bypass, aortic cross clamp time, deep hypothermia circulatory arrest time, dynamic changes of temperature, degree of hemodilution and blood gas management strategy.The influence of cardiopulmonary bypass on postoperative brain cognitive function in children with CHD is reviewed in this paper, in order to provide reference for clinical diagnosis and treatment, and to improve the prognosis of children with CHD.

Objective To investigate the preliminary clinical efficacy of percutaneous plate internal fixation with fracture reduction oriented forcep in the treatment of lower humeral fractures. Methods A retrospective case control study was conducted to analyze the clinical data of 46 patients with lower humeral fractures admitted to Wuzhong People's Hospital of Suzhou from October 2013 to March 2015. There were 25 males and 21 females, aged 19-76 years, with an average age of 45. 7 years. A total of 22 patients ( percutaneous group) were treated with minimally invasive percutaneous internal fixation with self-developed fracture reduction oriented forcep according to the dimensionality reduction method (DRM). The other 24 patients (control group) were treated with open reduction internal fixation. The length of incision, operation time, intraoperative blood loss, fracture healing time, the American Foot and Ankle Surgery Association ( AOFAS ) ankle-hindfoot score at the last follow-up, and postoperative complications were compared between the two groups. Results All patients were followed up for 12-24 months, with an average of 14. 6 months. There were statistically significant differences between percutaneous group and control group in incision length [(7.1 ±0.8)cm vs. (8.8 ±0.7)cm, operation time [(32.5 ±4.9)min vs. (39.2 ±4.3)min], intraoperative blood loss [(8.0 ±2.7) ml vs. (31.0 ± 11.4)ml], and fracture healing time (16.4 ±2.3)weeks vs. (19.5 ±2.9)weeks], respectively (all P<0.05). In percutaneous group, the AOFAS ankle-hindfoot score was (92.3 ±5.9)points (range, 75-99 points ) , and the overall results were good and excellent in 21/22 ( 96％) including excellent results in 18 patients, good in three, fair in one and poor in 0. In control group, the AOFAS ankle-hindfoot score was (91.8 ±4.9)points (range, 76-99 points), and the overall results were good and excellent in 23/24 (96％) including excellent results in 20 patients, good in three, fair in one and poor in 0. There was no significant difference in the excellent and good rate between two groups (P>0. 05). Poor wound healing was observed in one patient in control group. No case of nonunion was found in either group. Conclusion For lower humeral fractures, the percutaneous plate internal fixation with fracture reduction oriented forcep has the characteristics of simple operation, shortened operation time, reduced soft tissue injury and blood loss, and quick healing of the fracture, which is worthy of clinical application.

The correlation analysis between the neutrophil-lymphocyte ratio and systemic lupus erythematosus viscera involvement and disease activity / 中华肾脏病杂志

Objective To investigate the correlation between neutrophil-lymphocyte ratio (NLR) and disease activity of systemic lupus erythematosus (SLE),and the changes of NLR in different organ involvement of SLE patients.Methods A total of 155 SLE patients and 135 healthy controls from the Rheumatology Department of Xiangya Hospital were enrolled in this study from 2010 to 2018.Patients with SLE were divided into lupus nephritis group (LN group) and non-lupus nephritis group (non-LN group),serositis group and non-serositis group,according to whether they had kidney involvement or serositis.According to the SLE disease activity index 2000(SLEDAI-2000),the patients were divided into mild to moderate disease activity group (SLEDAI score ＜ 15) and severe disease activity group (SLEDAI score≥ 15).The NLR values of the above groups were compared.Spearman's correlation analysis was used to analyze the correlation between NLR and SLE patients' laboratory indexes.Multiple linear regression model was used to analyze the relationship between NLR and SLE disease activity.Receiver operating characteristic curve (ROC) was used to evaluate the value of NLR in SLE diagnosis and activity assessment.Results (1)The NLR value of SLE patients was significantly higher than that of healthy control group,and the difference was statistically significant (P ＜ 0.01).(2)The NLR value of SLE patients in the LN group was higher than that in the non-LN group,and the NLR value of SLE patients with serositis was higher than that in the group without serositis,with statistically significant differences (both P ＜ 0.05).(3)The NLR value of SLE patients in the severe disease activity group was higher than that in the mild and moderate disease activity group,and the difference was statistically significant (P ＜ 0.01).(4)NLR of SLE patients was positively correlated with CRP (rs=0.188,P=0.019),SLEDAI score (rs=0.264,P=0.001),and negatively correlated with total serum protein (rs=-0.250,P=0.002) and serum albumin (rs=-0.329,P ＜ 0.001),respectively.(5) Multiple linear regression showed that NLR was independently associated with SLE disease activity (B=0.351,95％CI 0.012-0.690,t=2.047,P=0.042).(6) According to ROC curve,the optimal cut-off value of NLR for SLE diagnosis was 2.17 (sensitivity 60.0％,specificity 83.1％,AUC=0.744),and the best cut-off value for predicting the activity of severe disease activity in SLE patients was 3.28 (sensitivity 58.5％,specificity 78.1％,AUC=0.700).Conclusion NLR is closely related to renal involvement,serositis and disease activity in SLE patients,which indicates that NLR,as a new inflammatory indicator,is of great significance for the assessment of SLE disease activity and organ involvement.

Endocrine-related injuries associated with immune checkpoint inhibitors: what endocrinologists and oncologists should know / 中华内分泌代谢杂志

The development of medications known as immune checkpoint inhibitors(ICPis) has been a milestone of cancer therapy. However, the increasing use of ICPis in recent years has caused a diverse spectrum of immune-related adverse events, including endocrine glands injury. ICPis-induced endocrinopathies are new challenges brought by advances of medicine as well as become the hot topics in both endocrinology and oncology. It is important that endocrinologists and oncologists should know how to perform proper assessment and clinical management once ICPis-induced endocrinopathies occur. Interdisciplinary collaboration is required to deal with this medical problem in order to improve overall survival and quality of life for patients with various cancer.

Porcine transcription factor AP-2δ promotes porcine circovirus type 2 replication through enhancing the activity of the rep gene promoter / 生物工程学报

Several putative transcription factor binding sites (TFBSs) exist in the PCV2 rep gene promoter. To explore if porcine circovirus type 2 (PCV2) could regulate the viral replication by using these TFBSs, we conducted electrophoretic mobility shift assay (EMSA), DNA-pull down and liquid chromatography-tandem mass spectrometric (LC-MS/MS) assays. EMSA confirmed the binding activity of the rep gene promoter with nuclear proteins of host cells. DNA-pull down and LC-MS/MS identified the porcine transcription factor AP-2δ (poTFAP2δ) could bind the PCV2 rep gene promoter. Dual-luciferase reporter assay, quantitative real-time PCR, Western blotting and indirect immunofluorescent assay demonstrated that poTFAP2δ could not only promote the activity of the rep gene promoter, but also enhance the transcription/translation activity of the rep/cap gene and the virus titer of PCV2 during the entire life cycle of PCV2 infection. This study revealed the molecular mechanism of PCV2 using host proteins to enhance the viral replication, provided a new perspective for studying the pathogenic mechanism of PCV2 from virus and host interactions, and provided a theoretical basis for developing highly effective PCV2 vaccines.

Hyperuricemia is an independent risk factor for renal pathological damage and poor prognosis in lupus nephritis patients / 中南大学学报(医学版)

To explore the correlation between hyperuricemia and renal damage in patients with lupus nephritis (LN).
 Methods: The data for clinical features, laboratory and renal pathological examination were collected from 177 renal biopsy-proven LN patients with or without hyperuricemia and were retrospectively analyzed to determine the correlation between serum uric acid and renal damage.
 Results: LN patients with hyperuricemia group had higher rate of hypertension and higher level of blood urea nitrogen and serum creatinine while lower estimated glomerular filtration rate (eGFR) and lower positive rate of anti-U1RNP antibody (P<0.05). In the LN patients with hyperuricemia group, renal pathological scores, including acitive index, chronic index and tubulointerstitial lesions, were higher than those in the LN patients without hyperuricemia group (P<0.05). The level of serum uric acid was positively correlated with serum creatinine, renal pathological classification and renal pathological scores while negatively correlated with eGFR (P<0.05).
 Conclusion: LN patients with hyperuricemia are associated with more serious renal damage. Hyperuricemia is an important predictor for poor prognosis in patients with LN.
