Objective:To analyze the impact of health education based on the integrated theory of health behavior change on the cardiac function, exercise endurance and nursing satisfaction in patients with chronic heart failure.Methods:In this randomized controlled trial, 130 patients with chronic heart failure admitted to Quzhou Hospital Affiliated with Wenzhou Medical University from June 2020 to December 2022 were selected as the research subjects. The patients were randomly divided into a control group and an experimental group (65 cases in each group) with a random number table method. The patients in the control group were given routine nursing care, the experimental group were given health education based on the integration theory of health behavior change on the basis of the control group, mainly including health assessment, health education, behavioral intervention, psychological support, etc. The intervention time for both group was 4 weeks. The independent sample t-test, χ2 test and Mann Whitney U test were applied to compare the improvement of cardiac function, plasma brain natriuretic peptide (BNP), echocardiographic indexes [left ventricular ejection fraction (LVEF), left ventricular volume index (LVMI) and left ventricular end-diastolic diameter (LVEDD)] and exercise endurance [maximum oxygen uptake (VO 2max), maximum power and exhaustion time] between the two groups, and the nursing satisfaction of the two groups was compared too. Based on the above results, the impact of health education based on the integrated theory of health behavior change on the cardiac function, exercise endurance and nursing satisfaction in patients with chronic heart failure were analyzed. Results:There was no statistically significant difference in various indicators between the two groups before intervention (all P>0.05). After the intervention, the BNP, LVMI and LVEDD in the experimental group were all clearly lower than those in the control group [(572.87±89.72) vs (680.46±104.32) mg/L, (140.74±9.54) vs (151.91±11.52) g/m 2 and (77.62±4.32) vs (80.31±5.57) mm, respectively], and they were all significantly lower than those before intervention [(963.41±228.69) mg/L, (170.33±12.61) g/m 2 and (90.10±6.77) mm, respectively]. The LVEF, the VO 2max, maximum power, exhaustion time, and nursing satisfaction in the experimental group were all significantly higher than those in the control group [54.55%±3.80% vs 52.16%±4.18%, (16.77±2.82) vs (15.61±3.15) ml·kg -1·ml -1, (88.91±7.13) vs (85.72±8.24) W, (13.47±1.62) vs (12.00±1.56) min, 95.4% vs 84.6%], and they were all significantly higher than those before intervention [50.11%±4.22%, (14.03±3.26) ml·kg -1·ml -1, (81.42±6.46) W, (10.02±0.82) min, respectively] (all P<0.05). Conclusion:Health education based on the integration theory of health behavior change is beneficial for improving the cardiac function, exercise endurance and nursing satisfaction in patients with chronic heart failure.

The WUSCHEL related-homeobox (WOX) family is one of the plant-specific transcription factor families, playing important roles in plant growth and development. In this study, 51 WOX gene family members were identified from the genome data of Brassica juncea by searching and screening with HUMMER, Smart and other software. Their protein molecular weight, amino acids numbers, and isoelectric point were analyzed by using Expasy online software. Furthermore, bioinformatics software was used to systematically analyze the evolutionary relationship, conservative region, and gene structure of the WOX gene family. The mustard WOX gene family was divided into three subfamilies: ancient clade, intermediate clade, and WUS clade/modern clade. Structural analysis showed that the type, organization form and gene structure of the conservative domain of WOX transcription factor family members in the same subfamily were highly consistent, while there was a certain diversity among different subfamilies. 51 WOX genes are distributed unevenly on 18 chromosomes of mustard. Most of the promoters of these genes contain cis acting elements related to light, hormone and abiotic stress. Using transcriptome data and real-time fluorescence quantitative PCR (qRT-PCR) analysis, it was found that the expression of mustard WOX gene was spatio-temporal specific, among which BjuWOX25, BjuWOX33, and BjuWOX49 might play an important role in the development of silique, and BjuWOX10, BjuWOX32, and BjuWOX11, BjuWOX23 respectively might play an important role in the response to drought and high temperature stresses. The above results may facilitate the functional study of mustard WOX gene family.

This recommendations includes the epidemiology, diagnosis, management, maternal care, medication treatment, care of birth and newborns, and psychological support associated with maternal SARS-CoV-2 infection. It is hoped that the recommendations will effectively help the clinical management of maternal SARS-CoV-2 infection.

【Objective】 To analyze the hepatitis B virus (HBV) infection data of blood donors from 18 domestic blood stations, so as to investigate the HBV infection situation of blood donors. 【Methods】 The positive rate of HBV and its distribution characteristics of regions, the percentage of HBsAg+ ELISA in first-time vs repeated blood donors, and the percentage of HBsAg-/HBV DNA+ blood donors of 18 domestic blood stations during 2017 to 2020 were collected from the Working Platform for Practice Comparison of Blood Centers, and the HBV infection among blood donors were statistically analyzed. 【Results】 From 2017 to 2020, the positive rate of HBV in blood donors among 18 domestic blood stations was 13.48/10 000-144.02/10 000, with the average HBV positive rate in eastern, central and western region at 26.14/10 000, 51.98/10 000 and 41.00/10 000, respectively. The HBsAg+ rate by ELISA among first-time and repeated blood donors was 14.55/10 000-305.39/10 000 vs 1.04/10 000-87.43/10 000 The HBsAg-/HBV DNA+ yield was 1.80/10 000-35.31/10 000. 【Conclusion】 The distribution of HBV infection in blood donors has regional characteristics, and HBV prevalence was low in repeated blood donors. HBsAg ELISA combined with HBV DNA detection can better ensure blood safety.

Objective:To summarize and analyze the current application status of oral mucosal graft (OMG) technique in the repair of ureteral strictures in China, and clarify the feasibility, safety and effectiveness of this technique.Methods:The 175 patients who underwent repair of ureteral stricture using oral mucosal patches from June 2015 to February 2022 were etrospectively analyzed in 14 medical centers in China, including 49 cases in Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, 32 cases in Affiliated Seventh Medical Center of PLA General Hospital, 3 cases in The Second Hospital of Anhui Medical University, 6 cases in The First Affiliated Hospital of Zhengzhou University, 56 cases in Peking University First Hospital, 3 cases in Sir Run Run Shaw Hospital, Zhejiang University School of Medicine, 3 cases in Shanghai Sixth People' s Hospital, 4 cases in General Hospital of Estern Theater Command, 4 cases in Lanzhou University Second Hospital, 2 cases in Guizhou Province People 's Hospital, 2 cases in Peking University People' s Hospital, 5 cases in Jinzhou First People's Hospital, 5 cases in The First Affiliated Hospital of Wannan Medical College, 1 case in Shandong Provincial Hospital. In this study, 127 patients (72.6%) used lingual mucosal patches, 32(18.3%) labial mucosa, and 16(9.1%) buccal mucosa. The surgical approach for OMG ureteral reconstruction was mainly minimally invasive, with robot-assisted laparoscopy in 84 patients (48.0%), traditional laparoscopic surgery in 87 patients (49.7%), and open surgery in only 4 patients (2.3%). There were 133 males and 42 females with an average age of (35.0±17.2) years. The mean body mass index (BMI) and stenosis length were (23.1±4.1) kg/m 2 and (4.7±1.8) cm, respectively. The stricture was located in the left ureter in 116 patients, right ureter in 58 case and bilateral ureter in 1 case. The most common causes of ureteral stricture were endoscopic surgery in 88(50.3%)patients, congenital stricture in 55(31.4%)patients, failed ureteroplasty in 29(16.6%)patients, history of extracorporeal shock wave lithotripsy in 13(7.4%)patients, radiotherapy history in 3(1.7%)patients and other causes in 6(3.4%)patients. Strictures were mainly located in the upper ureter, accounting for 61.7% (108/175 cases), followed by 36.0% (63/175) at the ureteropelvic junction and 2.3%(4/175)in the middle ureter. According to the surgical methods, the patients were divided into robot-assisted laparoscopic surgery group ( n=84), traditional laparoscopic surgery group ( n=87)and open surgery group ( n=4). Subgroup analysis of patients in robot-assisted laparoscopic and traditional laparoscopic surgery groups was performed. There were no significant difference in preoperative data between the two groups except for age (32.0±18.3) years vs.(37.0±15.9)years, P=0.040], BMI[(22.5±4.3)kg/m 2 vs. (23.7±3.6)kg/m 2, P=0.028], and etiology of stenosis [endoscopic injury, 34(40.5%) vs. 53(60.9%), P=0.012]. Preoperative hydronephrosis and stricture length were assessed by CTU and ureterography. Ureterography 7-9 weeks after surgery showed patency of the reconstructed segment, or no recurrence of hydronephrosis was judged as success. Evaluate the operation method, operation time, success rate, length of OMG in repairing ureteral stricture between laparoscopic and robot-assisted groups. Results:The overall success rate of oral mucosal graft repair surgery reached 97.7%(171/175). The success rate of ureteral reconstruction in the two groups were 96.4%(81/84)and 98.9%(86/87), respectively ( P=0.351), and the difference was not statistically significant. There was no significant difference for operation time, intraoperative blood loss, and mean oral mucosal length between the robotic and laparoscopic groups[(244.7±85.8) min and (222.7±83.5)min ( P=0.116), (58.9±38.6) ml and (68.4±45.5) ml ( P=0.217), (5.0±2.0) cm and (4.6±1.5) cm ( P=0.350)], respectively.Postoperative complications were reported in 23 (13.1%) patients, such as fever, urinary leakage, lymphatic leakage, infection, but only 2 (1.4%) cases patients had complications of Clavien-Dindo score ≥ Ⅲ. The two patients developed urinary stricture after surgery with failed conservative treatment, and no urinary stricture occurred following endoscopic treatment.The short-term (three months after surgery)incidence of complications in the site where the oral mucosa was taken, such as difficulty in opening mouth, pain, and swelling, was 12.0% (21/175), and there was no significant difference for oral complications between patients harvesting different length of mucosal graft. Conclusions:Ureteroplasty with oral mucosal graft is a safe, feasible and reliable technique for ureteral reconstruction. At present, minimally invasive technology is the main surgical approach for ureteroplasty, and there is no significant difference in operation time and success rate between robotic surgery and laparoscopic surgery.

Objective:To evaluate the clinical outcomes and safety of haploidentical hematopoietic stem cell transplantation (haplo-HSCT) using a conditioning regimen based on total body irradiation (TBI) and rabbit anti-human thymocyte globulin (rATG) in the management of chemotherapy-resistant advanced peripheral T-cell lymphoma (PTCL) .Methods:Clinical data of 11 patients with chemotherapy-resistant advanced PTCL who underwent haplo-HSCT with a TBI+rATG-based conditioning regimen at the Department of Hematology, Shanghai Liquan Hospital and Shanghai Zhaxin Integrated Traditional Chinese and Western Medicine Hospital, from September 2019 to December 2022 were retrospectively analyzed.Results:①Among the 11 patients (six males and five females), with a median age of 40 years (range: 22-58 years), there were six cases of PTCL, not otherwise specified (PTCL-NOS), three cases of angioimmunoblastic T-cell lymphoma (AITL), one case of large-cell transformation of mycosis fungoides (MF-LCT), and one case of T-cell large granular lymphocytic leukemia (T-LGLL). According to the Lugano staging system, all patients were in stage Ⅲ or Ⅳ, and eight patients had B symptoms. Before transplantation, the median number of prior lines of chemotherapy was 4 (range: 2-10), and all patients had progressive disease (PD). The median time from diagnosis to transplantation was 17 months (range: 6-36 months). ②The conditioning regimen consisted of a TBI dose of 10 Gy, administered at 2 Gy on day -8 and 4 Gy from day -7 to day -6, rATG was administered at a daily dose of 2.5 mg/kg from day -5 to day -2. Etoposide (VP-16) was given at a dose of 15 mg/kg/d from day -5 to day -4, while cyclophosphamide (CTX) was administered at a dose of 50 mg/kg/d from day -3 to day -2. In patients with central nervous system involvement, etoposide and cyclophosphamide were replaced with thiotepa (TT) at a dose of 5 mg/kg/d from day -5 to day -4. Additionally, cytarabine (Ara-C) was added at a dose of 2.0 g/m 2 twice a day from day -3 to day -2 into the conditioning. ③Successful engraftment was achieved in all patients, with a median time to neutrophil engraftment of 14.5 d (range: 11-16 d) and a median time to platelet engraftment of 13 days (range: 8-18 days). Acute graft-versus-host disease (aGVHD) occurred in one patient (grade Ⅰ-Ⅱ), and another patient experienced grade Ⅲ-Ⅳ aGVHD. Among the eight survivors, four developed chronic GVHD (cGVHD). ④Post-transplantation, nine patients achieved complete response (CR). ⑤Hematopoietic suppression occurred in all patients after conditioning, with three experiencing diarrhea, four developing mucositis, three exhibiting elevated transaminase/bilirubin levels, and seven developing infectious complications. These non-hematologic adverse events were effectively managed. ⑥At one year post-transplantation, the non-relapse mortality (NRM) was (22.5±14.0) %, the cumulative incidence of relapse (CIR) was (20.2±12.7) %, and overall survival (OS) rate was (72.7±13.4) %, and disease-free survival (DFS) rate was (63.6±14.5) % . Conclusion:TBI+rATG-based conditioning regimen for haplo-HSCT is an effective and safe treatment approach for patients with chemotherapy-resistant advanced PTCL.

ObjectiveTo investigate the level of humanized nursing abilities of nursing staff in rehabilitation department, and to explore the relationship with attitudes toward the persons with disabilities and work achievement. MethodsFrom December, 2020 to March, 2021, 196 nursing staff in rehabilitation department in eight tertiary hospitals in Jinzhou, Panjin, Yingkou and Fushun in Liaoning, China were investigated with attitude of healthcare professionals toward persons with disability scale, work achievement scale and Healthcare Professional Humanization Scale for Nursing (HUMAS). ResultsThe score of HUMAS was (73.39±10.75), and the average score of total items was (3.86±0.57). The scores of attitudes toward the persons with disabilities and work achievement positively correlated with the score of HUMAS (r = 0.208~0.774, P < 0.01). Work achievement partially mediated the attitudes toward the persons with disabilities and the humanized nursing abilities, with mediating effect of 0.420, accounting for 52.83% of the total effect. ConclusionThe humanized nursing ability of nursing staff in rehabilitation department needs to be improved. The better the attitudes toward the persons with disabilities are, the higher the work achievements are, the higher the humanized nursing abilities are. Attitudes toward the persons with disabilities among nursing staff in rehabilitation department may not only directly affect humanized nursing abilities, but also indirectly affect the humanized nursing abilities through the sense of work achievement.

BACKGROUND: Gestational diabetes mellitus (GDM) brings health issues for both mothers and offspring, and GDM prevention is as important as GDM management. It was shown that a history of GDM was significantly associated with a higher maternal risk for GDM recurrence. The incidence of GDM recurrence was unclear because of the incidence of second-child was low before 2016 in China. We aim to investigate the prevalence of GDM recurrence and its associated high-risk factors which may be useful for the prediction of GDM recurrence in China. METHODS: A retrospective study was conducted which enrolled participants who underwent regular prenatal examination and delivered twice in the same hospital of 18 research centers. All participants were enrolled from January 2018 to October 2018, where they delivered the second baby during this period. A total of 6204 women were enrolled in this study, and 1002 women with a history of GDM were analyzed further. All participants enrolled in the study had an oral glucose tolerance test (OGTT) result at 24 to 28 weeks and were diagnosed as GDM in the first pregnancy according to the OGTT value (when any one of the following values is met or exceeded to the 75-g OGTT: 0 h [fasting], ≥5.10 mmol/L; 1 h, ≥10.00 mmol/L; and 2 h, ≥8.50 mmol/L). The prevalence of GDM recurrence and development of type 2 diabetes mellitus were calculated, and its related risk factors were analyzed. RESULTS: In 6204 participants, there are 1002 women (1002/6204,16.15%) with a history of GDM and 5202 women (5202/6204, 83.85%) without a history of GDM. There are significant differences in age (32.43 ± 4.03 years vs. 33.00 ± 3.34 years vs. 32.19 ± 3.37 years, P  < 0.001), pregnancy interval (4.06 ± 1.44 years vs. 3.52 ± 1.43 years vs. 3.38 ± 1.35 years, P  = 0.004), prepregnancy body mass index (BMI) (27.40 ± 4.62 kg/m2vs. 23.50 ± 3.52 kg/m2vs. 22.55 ± 3.47 kg/m2, P < 0.001), history of delivered macrosomia (22.7% vs. 11.0% vs. 6.2%, P < 0.001) among the development of diabetes mellitus (DM), recurrence of GDM, and normal women. Moreover, it seems so important in the degree of abnormal glucose metabolism in the first pregnancy to the recurrence of GDM and the development of DM. There are significant differences in OGTT levels of the first pregnancy such as area under the curve of OGTT value (18.31 ± 1.90 mmol/L vs. 16.27 ± 1.93 mmol/L vs. 15.55 ± 1.92 mmol/L, P < 0.001), OGTT fasting value (5.43 ± 0.48 mmol/L vs. 5.16 ± 0.49 mmol/L vs. 5.02 ± 0.47 mmol/L, P < 0.001), OGTT 1-hour value (10.93 ± 1.34 mmol/L vs. 9.69 ± 1.53 mmol/L vs. 9.15 ± 1.58 mmol/L, P < 0.001), OGTT 2-hour value (9.30 ± 1.66 mmol/L vs. 8.01 ± 1.32 mmol/L vs. 7.79 ± 1.38 mmol/L, P < 0.001), incidence of impaired fasting glucose (IFG) (fasting plasma glucose ≥5.6 mmol/L) (31.3% vs. 14.6% vs. 8.8%, P < 0.001), and incidence of two or more abnormal OGTT values (68.8% vs. 39.7% vs. 23.9%, P < 0.001) among the three groups. Using multivariate analysis, the factors, such as age (1.07 [1.02-1.12], P = 0.006), prepregnancy BMI (1.07 [1.02, 1.12], P  = 0.003), and area under the curve of OGTT in the first pregnancy (1.14 [1.02, 1.26], P  = 0.02), have an effect on maternal GDM recurrence; the factors, such as age (1.28 [1.01-1.61], P  = 0.04), pre-pregnancy BMI (1.26 [1.04, 1.53], P = 0.02), and area under the curve of OGTT in the first pregnancy (1.65 [1.04, 2.62], P = 0.03), have an effect on maternal DM developed further. CONCLUSIONS The history of GDM was significantly associated with a higher maternal risk for GDM recurrence during follow-up after the first pregnancy. The associated risk factors for GDM recurrence or development of DM include age, high pre-pregnancy BMI, history of delivered macrosomia, the OGTT level in the first pregnancy, such as the high area under the curve of OGTT, IFG, and two or more abnormal OGTT values. To prevent GDM recurrence, women with a history of GDM should do the preconception counseling before preparing next pregnancy.

Objective:To explore the effect of exercise intervention on regulation of Toll-like receptor 4 (TLR4) signaling pathway in overweight and obese pregnant women.Methods:The cohort was based on a randomized controlled trial (RCT) carried out by the same research group in Peking University First Hospital from December 2014 to July 2016. Overweight and obese patients who delivered by elective cesarean section without pregnancy complications were recruited, among which 12 cases in the exercise group and 11 cases in the control group were selected. Real-time polymerase chain reaction, Western Blot, and Luminex experiments were used to compare the expression of TLR4-myeloid differentiation factor 8(MyD88)-nuclear factor-κB(NF-κB) pathway in peripheral blood mononuclear cell (PBMC), rectus abdominis muscle, omental adipose, and subcutaneous adipose, as well as the levels of inflammatory factors (TNF-α, IL-1β, IL-10) in plasma between the two groups. Two independent samples t-test, generalized estimating equation, Chi-square test, and Pearson correlation analysis were adopted for statistical analysis. Results:(1) The expression of inflammatory factors TNF-α and IL-1β in the exercise group showed a downward trend compared with the control in the second and third trimester, but none of the differences were statistically significant (all P>0.05). (2) The mRNA expression of TLR4, MyD88, and NF-κB and the protein expression of TLR4 and NF-κB in PBMC of the exercise group were significantly lower than those in the control group during pregnancy (TLR4 mRNA: 0.06±0.03 vs 0.10±0.04 in the second trimester, 0.05±0.02 vs 0.11±0.05 in the third trimester, χ2=8.07; MyD88 mRNA: 0.09±0.03 vs 0.11±0.03 in the second trimester, 0.10±0.04 vs 0.17±0.06 in the third trimester, χ2=5.81; NF-κB mRNA: 0.10±0.03 vs 0.17±0.08 in the second trimester, 0.08±0.03 vs 0.20±0.08 in the third trimester, χ2=14.71; TLR4 protein: 1.7±0.5 vs 1.9±0.8 in the second trimester, 1.7±0.4 vs 2.3±0.8 in the third trimester, χ2=5.83; NF-κB protein: 1.0±0.4 vs 1.5±0.4 in the second trimester, 1.2±0.3 vs 1.5±0.5 in the third trimester, χ2=4.73; all P<0.05). Moreover, the differences in the mRNA expression of TLR4, MyD88, and NF-κB and TLR4 protein expression in PBMC between the two groups gradually increased. (3) NF-κB in rectus abdominis and omental adipose tissue (0.04±0.02 vs 0.08±0.04, t=－3.72; 0.25±0.05 vs 0.63±0.21, t=－5.41; both P<0.05) and TLR4 and MyD88 in subcutaneous adipose tissue (0.12±0.03 vs 0.30±0.10, t=－5.30; 0.24±0.09 vs 0.44±0.08, t=－5.38; both P<0.05) were observed a decreased mRNA level in the exercise group compared with the control group. The protein level of MyD88 and NF-κB in omental adipose tissue and NF-κB in subcutaneous adipose tissue in the exercise group were significantly lower than those in the control group (1.1±0.5 vs 2.0±0.8, t=－3.15; 1.3±0.5 vs 2.0±0.9, t=－2.23; 1.2±0.5 vs 1.9±0.8, t=－2.80, all P<0.05). (4) The expressions of TLR4 and NF-κB mRNA ( r=0.453 and 0.485) in rectus abdominis muscle, NF-κB mRNA, TLR4 and MyD88 protein ( r=0.539, 0.437 and 0.527) in omental adipose in the two groups were positively correlated with the level of fasting blood glucose ( P<0.05). Conclusions:Regular exercise during pregnancy can down-regulate the expression and activation of the TLR4-MyD88-NFκB pathway in overweight and obese pregnant women. The expression of related factors along this pathway has a certain correlation with fasting blood glucose.

Perineal tear is a common complication of vaginal delivery and will seriously affect the quality of life of these women, if is severe. Given to there was no evidence-based clinical guideline for the prevention and management of perineal tear in China, this evidence-based guideline was developed, based on the methods of WHO handbook for guideline development. Systematic reviews were conducted according to the Cochrane handbook and GRADE was used to assess the quality and certainty of the evidence. Detailed recommendations are provided for 19 clinical questions in the prevention and management of perineal laceration, aiming to guide clinical practice and improve the quality of life of this group of women.
