ObjectiveTo investigate the effect of Naoqingtong decoction （NQT） on the kidney damage and the inflammatory factors NOD-like receptor protein 3 （NLRP3）， apoptosis-associated speck-like protein containing a C-terminal caspase recruitment domain （ASC）， cysteinyl aspartate-specific proteinase-1 （Caspase-1）， interleukin-6 （IL-6）， and tumor necrosis factor-α （TNF-α） in spontaneously hypertensive rats （SHRs）. MethodsTwenty-four SHRs were randomized into a model group， a low-dose （12.9 g·kg^-1·d^-1） NQT （NQT-L） group， a high-dose （25.8 g·kg^-1·d^-1） NQT group （NQT-H）， and a captopril （CTP， 20 mg·kg^-1·d^-1） group， with 6 rats in each group. In addition， 6 homozygous male Wistar-Kyoto rats were used as the control group. The control and model groups were administrated with the same amount of normal saline by gavage for 8 weeks. General behaviors of rats were observed during the intervention period， and the blood pressure was measured periodically. At the end of intervention， the body mass was weighed， and both kidneys were collected and weighed for the calculation of the renal index. Hematoxylin-eosin staining was performed to observe the pathological changes in the kidney tissue. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） and Western blot were employed to determine the expression levels of NLRP3， ASC， Caspase-1， IL-6， and TNF-α in the kidney tissue. ResultsDuring the experiment period， the control group had normal mental status， food intake， and activity， while the model group showed thinning of hair， loss of luster， reduced activity， loss of appetite， fecal adhesion， and irritability， and some of the skin had scratches or blood scabs. The above symptoms were alleviated to different degrees after 8 weeks of NQT administration. An intelligent non-invasive sphygmomanometer was used to measure the tail artery pressure of rats， which showed that the systolic and diastolic blood pressure of rats in the model group was higher than that in the control group （P<0.01）. Compared with the model group， drug interventions lowered the systolic and diastolic blood pressure （P<0.05， P<0.01）. Compared with the control group， the model group showed severe pathological damage in the kidney tissue， which was alleviated in each drug intervention group. Compared with the control group， the model group showed up-regulated expression levels of NLRP3， ASC， Caspase-1， IL-6， and TNF-α in the kidney tissue （P<0.05， P<0.01）. Compared with the model group， the drug intervention groups showed down-regulated expression levels of NLRP3， ASC， Caspase-1， IL-6， and TNF-α in the kidney tissue （P<0.05， P<0.01）. ConclusionNQT can lower the blood pressure in SHRs by inhibiting the activation of NLRP3 inflammasomes， suppressing renal inflammation， and ameliorating hypertensive kidney damage.

Background Lung cancer is a malignancy of high incidence rate and mortality in China.The fear of relapse can affect the patient's treatment compliance and reduce their quality of life.There have been previous studies on the relationship between fear of lung cancer relapse and disease perception,as well as disease perception and psychological flexibility.However,current research on the status quo of fear of lung cancer relapse and its correlation with illness perception and psychological flexibility is limited.Objective To explore the fear of cancer relapse and its relations with illness perception and psychological flexibility in patients with lung cancer,and to provide references for subsequent related clinical interventions.Methods A total of 96 patients were selected as the research subjects,who were pathologically diagnosed with lung cancer and admitted to Fuyang People's Hospital from January 2021 to July 2022.Fear of Progression Questionnaire-Short Form(FoP-Q-SF),Brief Illness Perception Questionnaire(BIPQ)and Acceptance and Action Questionnaire-Ⅱ(AAQ-Ⅱ)were used for evaluation.Pearson correlation analysis was used to examine the correlation between scores of various scales,and multiple linear regression analysis was used to explore the influencing factors of relapse fear in lung cancer patients.Results The total FoP-Q-SF score of lung cancer patients was(35.35±7.66)and a total of 65 cases(67.71%)had a FoP-Q-SF score&ge;34.As relevant analyses showed,the BIPQ total score of lung cancer patients was positively correlated with the total score,social family dimension score and physiological health dimension score of Fop-Q-SF(r=0.586,0.445,0.475,P<0.05),the AAQ-Ⅱ score was positively correlated with the total score,social family dimension score and physiological health dimension score of FoP-Q-SF(r=0.485,0.652,0.513,P<0.05).According to the results of single factor analysis and multiple linear regression analysis,age(β=-0.142,P<0.01),education level(β=-0.254,P<0.01),monthly household income(β=-0.527,P<0.01),illness perception(β=0.847,P<0.01)and psychological flexibility(β=0.781,P<0.01)are all factors influencing the fear of relapse in lung cancer patients.Conclusion Most lung cancer patients have a fear of recurrence.It is not only related to illness perception and psychological flexibility,but also influenced by factors including age,education level and monthly family income.

Conclusion:IMRT containing lymph node irradiation in the internal breast region after left breast cancer surgery brings a certain degree of increased cardiac dose, but it is feasible to control it within a certain range and does not affect the patients' cardiac function or quality of life in the short term.

OBJECTIVE: To analyze the clinical characteristics and spectrum of SPTB gene variants among 16 Chinese children with Hereditary spherocytosis (HS) and explore their genotype-phenotype correlation. METHODS: Sixteen children who were diagnosed with HS at the Affiliated Hospital of Capital Institute of Pediatrics from November 2018 to July 2022 were selected as the research subjects. Genetic testing was carried out by whole exome sequencing. Candidate variants were verified by Sanger sequencing and subjected to bioinformatic analysis and prediction of 3D structure of the protein. Correlation between the SPTB genotypes and clinical phenotypes was analyzed using Chi-squared test. RESULTS: The male-to-female ratio of the HS patients was 6 : 10, with the median age being 7-year-and-10-month. Clinical features of the patients have included anemia, reticulocytosis and gradual onset of splenomegaly. Mild, moderate and severe anemia have respectively occurred in 56.25% (9/16), 31.25% (5/16) and 12.50% (2/16) of the patients. SPTB gene variants were detected in all patients, among which 10 were unreported previously and 7 were de novo in origin. Loss of function (LOF) variants accounted for 93.75% (15/16). Only one missense variant was detected. Eleven, 4 and 1 of the variants had occurred in the repeat domain, CH1 domain, and dimerization domain, respectively. There was no significant correlation between the type or domain of the SPTB gene variants with the clinical features such as severity of anemia (x² = 3.345, P > 0.05). All of the variants were predicted to be pathogenic or likely pathogenic based on the guidelines from the American College of Medical Genetics and Genomics. CONCLUSION Mild to moderate anemia are predominant clinical features of the HS children harboring a SPTB gene variant, for which LOF variants are the main mutational type. The clinical feature of HS is unaffected by the type of the variants.

Objective To evaluate the changes in the right ventricular systolic and diastolic function during the early period after cardiopulmonary bypass (CPB) in patients undergoing coronary artery bypass grafting (CABG).Methods Eighteen ASA physical status Ⅱ or Ⅲ patients of both sexes,with coronary heart disease (NYHA Ⅱ or Ⅲ),aged 50-80 yr,weighing 51-96 kg,with left ventricular ejection fraction≥50％,scheduled for elective CABG under CPB,were enrolled in this study.Before splitting of sternum and at 5 min after termination of CPB,the parameters of hemodynamics,cardiac output (CO)and variables of right ventricular function (using transesophageal echocardiography) including tricuspid annular plane systolic excursion (TAPSE),right ventricular fractional area change (RVFAC),tricuspid annular peak velocity during isovolumic contraction (IVV),peak velocity during ejection phases (St),early diastolic peak velocity (Et),late diastolic peak velocity (At),E/Et ratio and Et/At ratio were recorded.Results Compared with the baseline value before splitting of sternum,TAPSE,IVV,St,RVFAC,CO,E,Et and At were significantly increased,and no significant change was found in the parameters of hemodynamics and E/Et and Et/At ratios at 5 min after termination of CPB.Conclusion For the patients undergoing CABG,the right ventricular systolic function is significantly enhanced,and there is no obvious improvement in the right ventricular diastolic function during the early period after CPB.

Objective To analyze the sensitivity and specificity of several volume parameters regarding volume responsiveness.The studied volume parameters include pulmonary artery obstruc-tion pressure (PAOP),central venous pressure (CVP),right ventricular end-diastolic volume (RV-EDV)measured by Swan-Ganz pulmonary artery catheter and left ventricular end-diastolic area (LVEDA),inferior vena cava diameter (IVC)measured by transesophageal echocardiography (TEE). Methods Twelve patients with ASA Ⅱ or Ⅲ,scheduled for coronary artery bypass grafting were studied.After anesthesia induction,the TEE probe was put into the esophagus and Swan-Ganz cathe-ter was placed in right internal jugular venous.Measurements were made at the time before cutting the skin (T0 ),20 min after divorcing from cardiopulmonary bypass or finishing vascular anastomosis in off-pump surgery(T1 ),10 min after rapid infusion (T2 )and 30 min after rapid infusion (T3 ),re-spectively.Results The values of PAOP,IVC,LVEDA,COLVOT at time T2 increased significantly compared to those at time T1 (P <0.01).No obvious correlation (r=-0.298 5、r=-0.091 8、r=-0.243 6)was observed between △CVP、△PAOP、△RVEDV and △COLVOT (the difference between T2 and T1 );Meanwhile,△IVC and △LVEDA were well correlated to △COLVOT (r= 0.445 0、r=0.612 0).Using more than 1 5% change of COLVOT after volume expansion as definition of positive re-sponse,the areas under the receiver operating characteristic curves of CVP,PAOP,RVEDV,IVC and LVEDA were 0.389 (95% CI 0.035-0.743 ),0.458 (95% CI 0.109-0.807 ),0.333 (95% CI 0-0.671 ), 0.903 (95% CI 0.701-1.000 ) and 0.889 (95% CI 0.661-1.000 ), respectively. Conclusion PAOP,IVC,LVEDA,CO are more sensitive to the change of volume;while CVP and RVEDV have weak responses to volume changes.This indicates that IVC and RVEDA have more ad-vantage to estimate cardiac output increase and guide volume therapy.

Objective To evaluate the changes in early left ventricular myocardial diastolic function after cardiopulmonary bypass (CPB) in the patients undergoing mitral valve replacement.Methods Twenty patients of both sexes,aged 40-70 yr,of ASA physical status Ⅱ or Ⅲ (NYHA Ⅱ or Ⅲ),with left ventricular ejection fraction (LVEF) ≥ 45 ％,scheduled for elective mitral valve replacement with CPB,were enrolled in the study.Global and regional left ventricular diastolic function was measured by using TEE.After splitting of sternum and at 30 and 90 min after termination of CPB,HR,mean arterial pressure,central venous pressure,cardiac index,LVEF,early diastolic transmitral velocity (E),early diastolic tissue velocity (Ea),right ventricular early myocardial velocity (Em) and right ventricular late myocardial velocity (Am).E/Ea and Em/Am ratios were calculated.Results There was no significant difference in the parameters of hemodynamics and left ventricular diastolic function at each time point before and after CPB.LVEF was greater than 50％ and E/Ea ratio was greater than 20 at each time point in the patients.Conclusion There is no further damage to the early left ventricular myocardial diastolic function after CPB in the patients undergoing mitral valve replacement.

Objective To evaluate the effect of sevoflurane preconditioning on the left ventricular function in patients undergoing coronary artery bypass grafting (CABG) with cardiopulmonary bypass (CPB).Methods Thirty ASA physical status Ⅱ or Ⅲ patients,aged 42-70 yr,with body height 152-181 cm,weighing 43-78 kg,scheduled for elective CABG under CPB,were randomly divided into 2 groups (n =15 each) using a random number table:control group (group C) and sevoflurane preconditioning group (group SP).Group SP inhaled sevoflurane with the end-tidal concentration corresponding to 1 MAC for 30 min after endotracheal intubation.Before sevoflurane preconditioning (T0) and at 60 min after termination of CPB (T1),mean arterial pressure (MAP),stroke volume index (SVI),pulmonary artery obstruction pressure and the TEE variables including left ventricular ejection fraction (LVEF),peak E wave velocity (E),systolic wave velocity (S),and diastolic wave velocity (D),and low propagation velocity (Vp) were recorded.S/D ratio and E/Vp ratio were calculated.Extubation time and duration of ICU stay were also recorded.Results Compared with the baseline value at T0,HR was significantly increased at T1 (P ＜ 0.05 or 0.01),and no significant change was found in the other parameters of the left ventricle function in the two groups (P ＞ 0.05).There was no significant difference in the parameters of the left ventricle function,extubation time and duration of ICU stay between SP group and C group (P ＞ 0.05).Conclusion Preconditioning with inhalation of sevoflurane with the end-tidal concentration corresponding to 1 MAC before CPB does not produce myocardial protection in terms of the left ventricular function or exerts little effect on the short-term outcomes.

In order to enhance the utilization efficiency, reduce the environmental pollution of traditional chemical treatment and the agriculture waste incineration; we studied the ligninase production by Coprinus comatus, Aspergillus niger and Trichoderma reesei through the plate screening. The results showed that C. comatus mixed culture with T. reesei have a good compatibility and higher yields of Laccase.
