Objective:To analyze the effect of birth parity on life expectancy (LE) and healthy life expectancy (HLE) among rural women.Method:A total of 15 304 women aged 40 to 79 years who participated in baseline and follow-up surveys were selected from a rural cohort in Henan province. The LE and HLE of women with different birth parity were calculated by using multi-state life table.Results:There were 1 195 (7.8%), 7 782 (50.8%), 3 867 (25.3%) and 2 460 (16.1%) women with 1, 2, 3 and 4 birth parities, respectively, and the M ( Q1 and Q3) of age were 50.3 (47.3, 53.4) and 53.3 (48.8, 60.7), 62.6 (55.4, 66.9) and 69.5 (64.7, 73.4) years old, respectively. LE at 40 years old was 44.5, 44.8, 45.1 and 45.4 years old, and HLE was 17.7, 18.3, 18.8 and 19.3 years old, respectively. LE at age 40 increased by 0.3, 0.6, and 0.9 years in women with 2, 3, and 4 birth parities or more and HLE increased by 0.5, 1.1, and 1.6 years, respectively, compared with women with 1 birth parity. For women with higher and lower socioeconomic status who had 4 birth parities or more, the LE at age 40 was 47.1 and 43.9 years, respectively, an increase of 0.2 and 0.1 years over women with 1 birth parity, respectively; and the HLE was 20.4 and 18.7 years, respectively, an increase of 1.4 and 1.3 years over women with 1 birth parity, respectively. Conclusion:LE and HLE show an upward trend with the increase of birth parity among rural women.

Background::Risk assessment and treatment stratification for three-vessel coronary disease (TVD) remain challenging. This study aimed to investigate the prognostic value of left atrial volume index (LAVI) with the Synergy Between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) score II, and its association with the long-term prognosis after three strategies (percutaneous coronary intervention [PCI], coronary artery bypass grafting [CABG], and medical therapy [MT]) in patients with TVD.Methods::This study was a post hoc analysis of a large, prospective cohort of patients with TVD in China, that aimed to determine the long-term outcomes after PCI, CABG, or optimal MT alone. A total of 8943 patients with TVD were consecutively enrolled between 2004 and 2011 at Fuwai Hospital. A total of 7818 patients with available baseline LAVI data were included in the study. Baseline, procedural, and follow-up data were collected. The primary endpoint was major adverse cardiac and cerebrovascular events (MACCE), which was a composite of all-cause death, myocardial infarction (MI), and stroke. Secondary endpoints included all-cause death, cardiac death, MI, revascularization, and stroke. Long-term outcomes were evaluated among LAVI quartile groups. Results::During a median follow-up of 6.6 years, a higher LAVI was strongly associated with increased risk of MACCE (Q3: hazard ratio [HR] 1.20, 95% confidence interval [CI] 1.06-1.37, P = 0.005; Q4: HR 1.85, 95%CI 1.64-2.09, P <0.001), all-cause death (Q3: HR 1.41, 95% CI 1.17-1.69, P <0.001; Q4: HR 2.54, 95%CI 2.16-3.00, P <0.001), and cardiac death (Q3: HR 1.81, 95% CI 1.39-2.37, P <0.001; Q4: HR 3.47, 95%CI 2.71-4.43, P <0.001). Moreover, LAVI significantly improved discrimination and reclassification of the SYNTAX score II. Notably, there was a significant interaction between LAVI quartiles and treatment strategies for MACCE. CABG was associated with lower risk of MACCE than MT alone, regardless of LAVI quartiles. Among patients in the fourth quartile, PCI was associated with significantly increased risk of cardiac death compared with CABG (HR: 5.25, 95% CI: 1.97-14.03, P = 0.001). Conclusions::LAVI is a potential index for risk stratification and therapeutic decision-making in patients with three-vessel coronary disease. CABG is associated with improved long-term outcomes compared with MT alone, regardless of LAVI quartiles. When LAVI is severely elevated, PCI is associated with higher risk of cardiac death than CABG.

Background::Sentinel lymph node (SLN) biopsy is gradually accepted as the standard of care in breast cancer patients with down-staged axillary disease after neoadjuvant chemotherapy (NAC). However, it is still difficult to precisely define pre-NAC clinical node-positive (cN1) and post-NAC clinical node-negative (ycN0). This prospective single-center trial was designed to evaluate the feasibility and accuracy of standard targeted axillary dissection (TAD) after NAC in highly selective pre-NAC cN1 patients (not considering ultrasound-based axillary ycN staging).Methods::This prospective trial included patients with initial pre-NAC cT1–3N1M0 invasive breast cancer but with a rigorous definition of cN1 from the Affiliated Cancer Hospital of Zhengzhou University. When NAC was effective (including complete and partial responses) and preoperative axillary palpation was negative, preoperative ultrasound-based axillary staging was not considered, and all patients underwent TAD followed by axillary lymph node (LN) dissection. The detection rate (DR) and false-negative rate (FNR) of TAD were calculated.Results::A total of 82 patients were included, and 77 of them were eligible for data analysis. The DR for TAD was 94.8% (73/77). There were 26 patients with one abnormal LN at the time of diagnosis based on ultrasound, 45 patients with two, and 2 patients with three. One patient had one TAD LN, four patients had two TAD LNs, and 68 patients had three or more TAD LNs. Preoperative axillary palpation yielded negative results for all 73 patients who successfully underwent TAD. Preoperative ultrasound-based ycN0 and ycN+ conditions were detected for 52 and 21 cases, respectively. The FNR was 7.4% (2/27) for standard TAD (≥3 SLNs), which was lower than that of all successful TAD (≥1 SLN; 10.0%, 3/30).Conclusions::In rigorously defined pre-NAC cN1 breast cancer patients, standard TAD is feasible for those with negative axillary palpation after NAC, and FNR is also less than 10%.Registration::chictr.org.cn, ChiCTR2100049093

Objective To compare the changes of the medical animal resources(MAR)in Sichuan based on the data of the 3rd Chinese Materia Medica Resource Inventory(CMMRI,1983-1986)and the 4th CMMRI(2020-2022).Methods After field investigation and identification of the photos of the animals,the data of the MAR in Sichuan found in the 4th CMMRI were analyzed and compared with the data of 3rd CMMRI.Results 745 species of MAR were found in Sichuan during the 4th CMMRI,including 212 families and 468 genera.Compared with the 108 species found in 3rd CMMRI,the number of MAR in Sichuan had greatly increased,The Aves was found to have 243 species of MAR,which is the most plenty one among the 7 classes.There were 14 families which have more than 10 species of MAR.The family,Cyprinidae had 48 species of MAR.There were 33 common Chinese medicinal herbs and 3 genuine medicinal materials including Cordyceps sinensis,musk and Venenum bufonis were found in this investigation.The new distributions of Liangshan Cordyceps and Cordyceps gunnii were found in the investigation,and the new resources of Atypus heterothecus was found in Mountain Emei.There were 140 species of key protection of wild medicinal animals,including 44 species of animals under first-class protection and 96 species of animals under second-class protection.There were 230 species of animals which had important ecological,scientific,and social values,too.Conclusion Sichuan was plenty of medical animal resources and the protection of the forest musk deer,the Cordyceps sinensis and the pangolin was need to be strengthened.

Interarterial subtype of coronary artery with anomalous aortic origin is a rare and congenital cardiovascular malformation,manifested by chest pain and syncope after exertion or activity,which can lead to decreased cardiac contractility,myocardial infarction,and even sudden death.Here we report a case of an adolescent patient,who presented with chest pain during activity accompanied by syncope and lost consciousness.Initially diagnosed with acute myocardial infarction,the patient was subsequently diagnosed as interarterial subtype of a coronary artery originating from anomalous aorta after echocardiography,coronary angiography,coronary CT angiography examinations.After anomalous coronary artery correction and coronary angioplasty,the paitent recovered well.

Objective    To investigate the prevalence, severity and consequences of acute kidney injury (AKI) in the patients who underwent total cavopulmonary connection (TCPC). Methods    The clinical data of TCPC patients in our center from January 1, 2010 to December 31, 2014 were collected and retrospectively analyzed. The patients with renal replacement therapy, missing serum creatinine data before operation or combined with valve procedures were excluded. We identified whether AKI was associated with hospital length of stay, ICU duration, mechanical ventilation duration, hospital acquired infection, and early mortality by univariable and multivariable analyses. Results    A total of 163 patients were included. AKI occurred in 57% of patients (n=93), mild AKI in 26.4% (n=43), moderate AKI in 12.3% (n=20) and severe AKI in 18.4% (n=30). Compared with the no AKI group, the AKI group had higher hospital acquired infection rate (15.1% vs. 0.0%, P<0.001). AKI was independently associated with hospital length of stay (median, 10 d, 95%CI  3.9-16.0,  P=0.001), ICU duration (median, 103.9, 95%CI 48.6-159.2, P<0.001) , but not associated with mechanical ventilation duration (median, 8 h vs. 7 h, P=0.529). Conclusion    Postoperative AKI in the patients undergoing TCPC is common. AKI is associated with higher hospital acquired infection rate, longer hospital length of stay and ICU duration, but not associated with mechanical ventilation duration.

Objective To identify the risk factors of ventilator-associated pneumonia (VAP) in infants after surgical correction for tetralogy of Fallot (TOF).Methods This study performed at Guangdong general hospital in China,130 infants (less than 12 months,mechanical ventilation time≥48 h) undergoing surgical correction for TOF were included between January 2013 and December 2017.Ventilator-associated pneumonia was defined according to the CDC/NHSN definitions guidelines issued in 2008.T test or Wilcoxon rank sum test was used in univariate analysis,and the variables with P ＜ 0.05 in the univariate analysis were added to a multiple logistic regression to identify the risk factors of VAP in infants after surgical correction for Tetralogy of Fallot.The area under the receiver operating characteristic (ROC) curve was calculated as a measure of accuracy.Results A total of 130 infants were included,however,VAP was found in 34 (26.2％) infants.The single variables significantly associated with a risk of VAP were:pre-operative hypoxic,pre-operative pneumonia,pre-operative mechanical ventilation support,prolonged cardiopulmonary bypass time,reintubation,pulmonary atelectasis,pleural effusion hydrothorax,prolonged mechanical ventilation support time,low cardiac output and transfusion of erythrocyte concentrate or fresh frozen plasma.Multiple logistic regression analysis showed prolonged cardiopulmonary bypass time (OR =1.02),reintubation (OR =16.111),pulmonary atelectasis (OR =8.133),low cardiac output (OR =7.649) and prolonged mechanical ventilation support time (OR =1.014) were independent risk factors for VAP in infants after TOF surgical correction.The area under the curve demonstrates the accuracy of the model.Conclusion The occurrence rate of VAP was high and risk factors for VAP after TOF surgical correction were complex.These results can be used to prevent and reduce the occurrence of VAP.
