OBJECTIVE:To explore the effects of umbilical therapy by Rheum plamatum combined with early colonic irriga-tion on the quality of life in elderly patients with colon stoma. METHODS:80 patients underwent radical resection of abdominoperi-neal rectal carcinoma were randomly divided into control group and observation,with 40 cases in each group. Control group was given early colonic irrigation;observation group was additionally given umbilical therapy by R. plamatum. Treatment course of 2 groups lasted for one month,and both were followed up for 6 months after treatment. The quality by life in 2 groups was evaluated by using QLQ-C30,and therapy costs were calculated before and after treatment. RESULTS:Compared with before treatment, function score and total health score of 2 groups improved significantly in 1,3,6 months after treatment,while symptom score and single item score decreased significantly,with statistical significance(P<0.05). In 1,3,6 months after treatment,role func-tion,social function,cognitive function,emotional function and total health score of observation group were significantly higher than those of control group,and insomnia and pain score were significantly lower than control group,with statistical significance (P<0.05). 3 and 6 months after treatment,diarrhea and economic difficulty score of observation group were significantly lower than those of control group,with statistical significance(P<0.05). 1 months after treatment,loss of appetite score of observation group were significantly lower than those of control group,with statistical significance (P<0.05). 6 months after treatment, fa-tigue,nausea and vomiting score of observation group were significantly lower than those of control group,with statistical signifi-cance (P<0.05). 6 months after treatment,nursing cost,drug cost and total cost of observation group were significantly lower than those of control group,with statistical significance(P<0.05). CONCLUSIONS:The umbilical therapy by R. plamatum com-bined with early colonic irrigation can improve the quality of life in elderly patients with colon stoma significantly and reduce treat-ment cost.

AIM:To construct myocardium-specific nucleolin ( Ncl) transgenic mice and to provide an animal model for the studies of the myocardial protection of nucleolin .METHODS:To create nucleolin transgenic mice , a myo-cardium-specific expression plasmid of nucleolin ( Alpha-MyHC clone 26-Ncl) was constructed .The gene type of transgenic mice was identified by PCR and the nucleolin protein level was tested by Western blotting .The myocardium morphology , heart weight index (HWI) and left ventricular pressure maximum rise rate were observed in nucleolin transgenic (TG) mice and wild-type ( WT) mice.RESULTS:We gained 4 transgenic mice (51, 52, 56 and 86 lines, only 52 line and 86 line were eugonic) by PCR.Western blotting analysis showed the expression of nucleolin up-regulated specifically in the myocardium .However , the myocardium morphology , HWI and left ventricular pressure maximum rise rate in the nucleolin transgenic mice were similar to those in the wild-type mice.CONCLUSION:We constructed myocardium-specific nucleo-lin transgenic mice successfully .

AIM: To investigate the effect of nucleolin on diabetic cardiomyopathy in mice.METHODS: A type II diabetic cardiomyopathy mouse model was prepared using a cardiac-specific nucleolin-overexpressing transgenic mice.The mice were divided into wild-type mouse control group, nucleolin transgenic mouse control group, wild-type mouse diabetes group and nucleolin transgenic mouse diabetes group.Wheat germ agglutinin (WGA) fluorescent dye, Masson staining and PowerLab system detection were used to further clarify the role of nucleolin on cardiac hypertrophy, fibrosis and cardiac function in type II diabetic cardiomyopathy mice.RESULTS: Compared with wild-type mouse control group, no significant increase in blood glucose level was found, while genetical myocardial cell hypertrophy was significantly attenuated in nucleolin transgenic mouse diabetes group.The collagen fibers were also significantly reduced, and hemodynamic indexes ± dp/dtmax, left ventricular end-diastolic pressure, left ventricular systolic pressure and heart rate were also improved.The above differences were statistically significant.CONCLUSION: Nucleolin may reduce the occurrence of myocardial hypertrophy and fibrosis, thus improving the cardiac function of diabetic cardiomyopathy mice.

Purpose: Anxiety, depression, and poor quality of life (QOL) were considered important concerns that hindered the rehabilitation of breast cancer survivors. A number of studies have investigated the effects of physical activity, but they have not reached the same conclusions. This review aimed to identify the effects of physical activity on QOL, anxiety, and depression in breast cancer survivors. Methods: PubMed, Embase, Web of Science, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycINFO, SinoMed, CNKI, Vip, and WanFang databases were searched for the time period between January 1, 2012, and April 30, 2022. Studies were included if they were randomized controlled trials of the effects of physical activity on QOL, anxiety, or depression in breast cancer survivors. The tools of the Joanna Briggs Institute were used to assess the quality of the included studies. R software version 4.3.1 was used for meta-analysis. Results: A total of 26 studies, involving 2105 participants, were included in the systematic review. Among these, 20 studies involving 1228 participants were included in the meta-analysis. Compared with the control group, the results indicated that physical activity can significantly improve QOL(Hedges' g = 0.67; 95% CI 0.41–0.92) and reduce anxiety (Hedges' g = −0.28; 95% CI −0.46 to −0.10) in breast cancer survivors. However, the effect of physical activity on depression (Hedges' g = −0.46; 95% CI −0.99 to 0.06) was not statistically significant. Conclusions Physical activity was an effective intervention to improve QOL and reduce anxiety in breast cancer survivors, as well as showed positive trends in depression, although without statistical significance. More well-designed studies are required to clarify the effects of different types of physical activities on the QOL, anxiety, and depression among breast cancer survivors.

OBJECTIVE: To investigate the nucleolus expression in the diabetic cardiomyopathy. METHODS: The rats were divided into a control group and a type II diabetic cardiomyopathy group (model group). In the model group, rats were fed with high-fat and high-sugar food (rats were intravenously injected with 60 mg/kg chain urea with cephalosporins in the 5th and 6th weeks in mice). The level of blood glucose was determined at the end of 8th week and the level of fasting blood glucose was examined at the end of 20th week. The ratio of the heart mass and body mass was calculated, and the pathological changes in myocardial morphology were observed. The immunohistochemical method and Western blot were used to detect the expression level of myocardial nucleolin. RESULTS: The level of fasting blood glucose was significantly increased in the diabetic model group than that in the control group (P<0.05). Rats in the model group were found hypertrophic cardic cells, with fracture, dissolusion, and disordered arrangement. Immunohistochemical staining and Western blot showed the protein levels of myocardial nucleolin in the model group were obviously higher than those in the control group (P<0.05). CONCLUSION Nucleolin may play a role in the pathogenesis and development of the diabetic cardiomyopathy.

Objective To analyze the clinical features and prognosis of acute myeloid leukemia (AML) patients with incomplete blood recovery [platelet count (Plt) < 100 ×109/L or absolute neutrophil count (ANC)<1.0×109/L] at the first time of achieving morphologic complete remission(CR). Methods The clinical data of 302 AML patients (non-M3) who were treated at the First Affiliated Hospital of Zhengzhou University from January 2010 to September 2015 were retrospectively reviewed. They were divided into CR group (Plt≥100×109/L and ANC≥1.0×109/L) and CR with incomplete blood recovery group (Plt<100×109/L or ANC<1.0 ×109/L) according to the condition of blood count at the first time of achieving morphologic CR. The clinical features and prognostic differences between the two groups were compared, and univariate analysis and mutivariate analysis were performed to compare the recurrence and survival of AML with incomplete blood recovery. Results Two hundred and sixteen (71.5%) patients were in CR group and 86 (28.5%) were in CR with incomplete blood recovery group. There was no statistically difference between the two groups in terms of age, high white blood cell, peripheral blasts ratio, France-American-Britain (FAB) type, cytogenetic risk classification and FLT3-ITD/NPM1 gene mutation (all P>0.05). Bone marrow blasts before therapy and the proportion of bone marrow CR in the first course of chemotherapy in CR group were higher than those in CR with incomplete blood recovery group (both P< 0.05), and the proportion of minimal residual disease (MRD) positive patients was lower in CR group (P=0.004). Bone marrow proliferation at the time of achieving morphologic CR was more active in CR group (P=0.001). The 3-year relapse rate in CR group was lower than that in CR with incomplete blood recovery group (P= 0.003), and overall survival (OS) rate and disease-free survival (DFS) rate were higher than those in CR with incomplete blood recovery group (both P< 0.05). Multivariate prognostic analysis for relapse, OS rate and DFS rate showed that high risk karyotype,≥2 courses of induction therapy and neutrophils not recovery were independent risk factors for AML patients with incomplete blood recovery (all P>0.05). In addition, FLT3-ITD positive was an independent risk factor for OS rate(P< 0.001), and peripheral blood blasts ≥0.60 was an independent risk factor for DFS rate (P= 0.047). Conclusions AML patients with incomplete blood recovery at the first time of achieving morphologic CR have a poor prognosis. AML patients with high-risk karyotype, ≥2 courses of induction therapy, incomplete neutrophils recovery may have a worse prognosis, and they should be regarded as high-risk groups and given more aggressive treatment.

Objective:To optimize the strategy of Nuss procedure with open approach via median sternotomy for pectus excavatum(PE) with congenital heart disease(CHD).Methods:25 PE patients with CHD treated in our center from January 2017 to November 2021 were reviewed and divided into two groups. The CHD surgery and open Nuss procedure with median sternotomy were performed concomitantly in 9 cases(group A), whose height of(121.7±28.0)cm, weight of(22.2±14.0)kg, age of(7.65±4.08) years old, and Haller index of 3.99±1.37. 16 cases underwent open Nuss procedure via median re-sternotomy after congenital heart surgery(group B), whose height of(130.9±27.2)cm, weight of(26.5±14.3)kg, age of(8.82±4.09) years old, and Haller index of 4.18 ± 0.97. The cardiac anatomy, cardiac function and the severity of PE of all patients were evaluated by echocardiography and computed tomography preoperatively. The preoperative gender, appearance of PE, types of associated CHD, retrosternal adhesion and the interval between open Nuss procedure and CHD surgery were collected. The details of operation, hospital stay, intraoperative adverse events, postoperative complications and follow-up were collected.Results:All the operations were accomplished successfully in 25 children. No intraoperative complications occurred. One had a postoperative wound infection in group A. The operation time of group A was significantly longer than that of group B[(3.78±1.54) h vs.(2.19±0.94) h, P<0.05]. There was no significant difference in the mechanical ventilation time between the two groups[(22.50±45.64) h vs.(4.18±1.41) h, P=0.263]. The ICU stay of group A was significantly longer than that of group B[(4.00±6.42) days vs.(1.13±0.34) days, P<0.05]. There was no significant difference in the length of hospital stay between the two groups[(16.00±15.18) days vs.(9.19±2.31) days, P=0.419]. The Nuss bar was removed in 14 cases of the two groups, with a interval of(27.9±11.25) months after open Nuss procedure, the postoperative Haller Index was 2.48±0.49. There was no difference of LVEF in postoperative and preoperative echocardiography(0.663±0.028 vs. 0.659±0.038, P=0.533). The FVC and FEV1 were significantly improved compared with before operation[(87.2±3.9)% vs.(84.1±8.2)%]. The outcome was good. Conclusion:For PE patients with CHD, one-stage or staged individualized Nuss procedure with open approach via median sternotomy can be performed after careful preoperative evaluation. A skillful median re-sternotomy and widely dissecting retrosternal adhesion between sternum and anterior wall of heart are necessary to avoid serious intraoperative complications such as massive heart bleeding and ensure good sternal elevation.

Objective Mitral valve regurgitation often leads to cardiac insufficiency or even heart failure .Methods We tried a mitral valve annuloplasty with a ring to improve the effect of mitral valvuloplasty , 5 males and 6 females; aged(8.0 ± 4.5)years;weight(26.1 ±13.9)kg.From February 2015 to December 2017, 11 children underwent mitral valve annuloplasty with an mitral valve ring in our hospital.Immediately after surgery, the degree of mitral valve regurgitation was significant im-proved from moderate-severe to mild-moderate(P<0.05).Results 1 case of early death, 1 case had a mitral valve replace-ment because of early hemolysis.The rest of the children were discharged smoothly.The follow-up of 3 months of mitral valve regurgitation was not aggravated comparing with that immediately after surgery(P>0.05).There was no worsening of cardiac function at follow-up(P>0.05), and no other adverse events.Therefore, artificial mitral annuloplasty with a ring is effective in treating mitral regurgitation in children .The annulus had potential growth characteristics and did not require lifelong oral an-ticoagulant.Conclusion For some patients with difficulty, this method of mitral valvuloplasty can enlarge the surgical indica-tion and improve the quality of life of children.The treatment effect is good.

Objective:To observe the clinical characteristics of pressure regulation frequency of shunt pump in patients with hydrocephalus after ventriculoperitoneal shunt, and explore the correlation between frequencies of shunt pump and prognoses of these patients.Methods:One hundred and one patients underwent ventriculoperitoneal shunt in our hospital from January 2018 to December 2018 were selected. According to the frequencies of postoperative pressure regulation of these patients, they were divided into non-pressure regulation group, low-frequency pressure regulation group (1-2 times) and high-frequency pressure regulation group (2 times or more). The relations of high-pressure hydrocephalus/normal pressure hydrocephalus with pressure regulation frequency, and relation between causes of pressure regulation and pressure regulation frequency were compared, and the prognoses of patients with different pressure regulation frequencies were analyzed.Results:Among the 101 patients with implanted adjustable pressure shunt, 34 had no pressure regulation after surgery, 52 had low-frequency pressure regulation, and 15 had high-frequency pressure regulation. The percentages of patients accepted low-frequency pressure regulation and high-frequency pressure regulation in patients with high-pressure hydrocephalus were significantly higher than those with normal pressure hydrocephalus ( P<0.05). The proportions of patients with insufficient shunt, excessive shunt or magnetic field interference in the low-frequency pressure regulation group were significantly higher than those in the high-frequency pressure regulation group ( P<0.05), while the proportions of patients with abnormal shunt (stagger of insufficient shunt, excessive shunt) in the low-frequency pressure regulation group were significantly lower than those in the high-frequency pressure regulation group ( P<0.05). There were 7 patients with poor curative effect, including 4 patients from the low-frequency pressure regulation group and 3 from the high-frequency pressure regulation group. The prognoses of patients with different pressure regulation frequencies were statistically different( P<0.05), the good prognosis rate of patients in the non-pressure regulation group, low-frequency pressure regulation group and high-frequency pressure regulation group decreased successively. Conclusion:About 66.3% patients need pressure regulation treatment again after hydrocephalus-ventriculoperitoneal shunt; the rate of poor efficacy in patients accepted high-frequency pressure regulation is obviously higher than that in patients accepted low-frequency pressure regulation, which needs clinical attention.

The "vicious cycle" established between tumor growth and osteolysis aggravates the process of breast cancer bone metastasis, leading to life-threatening skeletal-related events that severely reduce survival and quality of life. To effectively interrupt the "vicious cycle", innovative therapeutic strategies that not only reduce osteolysis but also relieve tumor burden are urgently needed. Herein, a bone-seeking moiety, alendronate (ALN), functionalized coordination polymer nanoparticles (DZ@ALN) co-delivering cisplatin prodrug (DSP) and antiresorptive agent zoledronate (ZOL)
