Objective:To explore the relationship between hemoglobin variability (Hb-var) and risk of all-cause death and cardiovascular death in patients with peritoneal dialysis (PD), and to provide basis for reducing the risk of death in PD patients.Methods:It was a multicenter retrospective cohort study. The clinical data of regular PD patients from Nanfang Hospital of Southern Medical University, Shunde Hospital of Southern Medical University, Foshan First People's Hospital and Ganzhou People's Hospital from July 1, 2008 to December 31, 2019 were collected. Hb-var was calculated based on hemoglobin at baseline before PD and in the first year after PD. The patients were divided into low Hb-var group, moderate Hb-var group and high Hb-var group according to the tertiles of first year Hb-var, and the differences of baseline clinical data among three groups were compared. Follow-up endpoints included death, transfer to hemodialysis, transfer to kidney transplantation, transfer to other centers, loss of follow-up, or on December 31, 2021. Cox regression analysis model was used to analyze the association of the first-year Hb-var with all-cause death and cardiovascular death. Fine-Gray competitive risk regression model was used to evaluate the impact of competitive events on mortality risk.Results:A total of 1 562 patients with PD were included in the study, aged (47.6±13.8) years old, with 821 males (52.6%) and baseline hemoglobin of 81 (69, 94) g/L. Hb-var in the first year of PD was 26.6 (16.7, 40.3) g/L. There were statistically significant differences in age, body mass index, serum albumin, hemoglobin, serum creatinine, serum calcium, serum phosphorus, intact parathyroid hormone and the proportion of renin-angiotensin system inhibitors among low Hb-var group (<20.0 g/L), moderate Hb-var group (20.0-35.5 g/L) and high Hb-var group (≥35.5 g/L, all P<0.05). The follow-up time was 33 (19, 51) months, and 208 patients (13.3%) died, among which 111 patients (53.4%) died of cardiovascular death. Multivariate Cox regression analysis showed that the higher Hb-var in the first year, the lower the risk of all-cause death ( HR=0.98, 95% CI 0.97-0.99, P=0.018) and cardiovascular death ( HR=0.98, 95% CI 0.97-0.99, P=0.041) in PD patients. Compared with low Hb-var group, the risk of all-cause death ( HR=0.56, 95% CI 0.37-0.82, P=0.003) and cardiovascular death ( HR=0.54, 95% CI 0.31-0.95, P=0.032) was lowest in the high Hb-var group. The competitive risk regression model analysis showed that Hb-var in the first year was still negatively correlated with the risk of all-cause death ( HR=0.98, 95% CI 0.97-0.99, P=0.041) and cardiovascular death ( HR=0.98, 95% CI 0.97-0.99, P=0.039). Conclusion:High Hb-var in the first year is associated with low risk of all-cause death and cardiovascular death in PD patients with severe anemia at baseline.

This paper reviews the researches on acupuncture preconditioning before surgery in recent years and explores its application value from three aspects, i.e. relieving preoperative anxiety, preventing from postoperative cognitive dysfunction, and preventing from postoperative gastrointestinal dysfunction. As a relatively safe non-drug treatment, acupuncture has the underlying advantages in participating into multidisciplinary coordination in the enhanced recovery after surgery (ERAS). By building up higher-quality medical evidences and revealing the effect mechanism of acupuncture from multi-dimenisonal aspects, it is expected that acupuncture technology can be coordinated with ERAS to optimize the clinical path in the perioperative period, and boost the development of the perioperative medicine ultimately.

OBJECTIVES: To investigate the clinical treatment outcomes and the changes of the outcomes over time in extremely preterm twins in Guangdong Province, China. METHODS: A retrospective analysis was performed for 269 pairs of extremely preterm twins with a gestational age of <28 weeks who were admitted to the department of neonatology in 26 grade A tertiary hospitals in Guangdong Province from January 2008 to December 2017. According to the admission time, they were divided into two groups: 2008-2012 and 2013-2017. Besides, each pair of twins was divided into the heavier infant and the lighter infant subgroups according to birth weight. The perinatal data of mothers and hospitalization data of neonates were collected. The survival rate of twins and the incidence rate of complications were compared between the 2008-2012 and 2013-2017 groups. RESULTS: Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of severe asphyxia and smaller head circumference at birth (P<0.05). The mortality rates of both of the twins, the heavier infant of the twins, and the lighter infant of the twins were lower in the 2013-2017 group compared with the 2008-2012 group (P<0.05). Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of pulmonary hemorrhage, patent ductus arteriosus (PDA), periventricular-intraventricular hemorrhage (P-IVH), and neonatal respiratory distress syndrome (NRDS) and a higher incidence rate of bronchopulmonary dysplasia (P<0.05). CONCLUSIONS There is a significant increase in the survival rate over time in extremely preterm twins with a gestational age of <28 weeks in the 26 grade A tertiary hospitals in Guangdong Province. The incidences of severe asphyxia, pulmonary hemorrhage, PDA, P-IVH, and NRDS decrease in both the heavier and lighter infants of the twins, but the incidence of bronchopulmonary dysplasia increases. With the improvement of diagnosis and treatment, the multidisciplinary collaboration between different fields of fetal medicine including prenatal diagnosis, obstetrics, and neonatology is needed in the future to jointly develop management strategies for twin pregnancy.

Objective:To explore the relationship between low serum albumin levels and its duration on first episode of peritonitis in peritoneal dialysis (PD) patients.Methods:PD patients who were regularly followed up in the Pearl River Delta region from September 1, 2000 to July 6, 2021 in Shunde Hospital of Southern Medical University, Nanfang Hospital of Southern Medical University, and Foshan First People′s Hospital were retrospectively selected. The patients were divided into low serum albumin group (LSA group, mean albumin<35 g/L), moderate serum albumin group (MSA group, 35 g/L≤mean albumin<40 g/L) and high serum albumin group (HSA group, mean albumin≥40 g/L) according to the mean albumin of the patients, and the differences among the three groups were compared. The Kaplan-Meier survival analysis method was used to compare the risk of peritonitis events in different mean albumin groups and different durations of hypoalbuminemia. The multivariate Cox regression model was used to analyze the relationship between serum albumin levels and duration of hypoalbuminemia and new-onset peritonitis.Results:A total of 1 853 PD patients were included in this study, aged (49.72±15.34) years, and 1 036(55.9%) males. There were 551 patients (29.7%) in the LSA group, 920 patients (49.7%) in the MSA group, and 382 patients (20.6%) in the HSA group. The median follow-up was 37 (15, 66) months and there were 508 patients (27.4%) with new-onset peritonitis during the follow-up. Compared with the LSA group, the incidence of new peritonitis in the MSA group and HSA group was lower ( χ2=14.053, P<0.001; χ2=21.857, P<0.001), but there was no significant difference in the incidence of new peritonitis between the HSA group and MSA group. The Kaplan-Meier survival analysis showed that the cumulative incidence of peritonitis in the LSA group was significantly higher than that in the MSA group and HSA group (Log-rank χ2=22.128, P<0.001). Compared with PD patients with normal serum albumin, the patients with longer duration of hypoalbuminemia tended to have a higher incidence of new peritonitis. Multivariate Cox regression analysis showed that the mean albumin<35 g/L (LSA group/MSA group, HR=1.495, 95% CI 1.198-1.866, P<0.001; LSA group/HSA group, HR=1.459, 95% CI 1.104-1.928, P=0.008) was an independent risk factor of new-onset peritonitis in PD patients and the prolongation of duration of hypoalbuminemia had a significantly higher risk of new-onset peritonitis ( HR=1.013, 95% CI 1.003-1.024, P=0.014). Conclusion:The mean albumin<35 g/L and prolong duration of hypoalbuminemia are independent risk factors of PD-related peritonitis in PD patients.

There is urgent need to discover effective traditional Chinese medicine(TCM) for treating coronavirus disease 2019(COVID-19). The development of a bioinformatic tool is beneficial to predict the efficacy of TCM against COVID-19. Here we deve-loped a prediction platform TCMATCOV to predict the efficacy of the anti-coronavirus pneumonia effect of TCM, based on the interaction network imitating the disease network of COVID-19. This COVID-19 network model was constructed by protein-protein interactions of differentially expressed genes in mouse pneumonia caused by SARS-CoV and cytokines specifically up-regulated by COVID-19. TCMATCOV adopted quantitative evaluation algorithm of disease network disturbance after multi-target drug attack to predict potential drug effects. Based on the TCMATCOV platform, 106 TCM were calculated and predicted. Among them, the TCM with a high disturbance score account for a high proportion of the classic anti-COVID-19 prescriptions used by clinicians, suggesting that TCMATCOV has a good prediction ability to discover the effective TCM. The five flavors of Chinese medicine with a disturbance score greater than 1 are mainly spicy and bitter. The main meridian of these TCM is lung, heart, spleen, liver, and stomach meridian. The TCM related with QI and warm TCM have higher disturbance score. As a prediction tool for anti-COVID-19 TCM prescription, TCMATCOV platform possesses the potential to discovery possible effective TCM against COVID-19.

Objective: To evaluate the efficacy and safety of pegylated recombinant human granulocyte colony-stimulating factor (PEG-rhG-CSF) in prophylaxis neutropenia after chemotherapy in patients with lymphoma. Methods: This was a multicenter, single arm, open, phase Ⅳ clinical trial. Included 410 patients with lymphoma received multiple cycles of chemotherapy and PEG-rhG-CSF was administrated as prophylactic. The primary endpoint was the incidence of Ⅲ/Ⅳ grade neutropenia and febrile neutropenia (FN) after each chemotherapy cycle. Meanwhile the rate of antibiotics application during the whole period of chemotherapy was observed. Results: ①Among the 410 patients, 8 cases (1.95%) were contrary to the selected criteria, 35 cases (8.54%) lost, 19 cases (4.63%) experienced adverse events, 12 cases (2.93%) were eligible for the termination criteria, 15 cases (3.66%) develpoed disease progression or recurrence, thus the rest 321 cases (78.29%) were into the Per Protocol Set. ②During the first to fourth treatment cycles, the incidences of grade Ⅳ neutropenia after prophylactic use of PEG-rhG-CSF were 19.14% (49/256) , 12.5% (32/256) , 12.18% (24/197) , 13.61% (20/147) , respectively. The incidences of FN were 3.52% (9/256) , 0.39% (1/256) , 2.54% (5/197) , 2.04% (3/147) , respectively. After secondary prophylactic use of PEG-rhG-CSF, the incidences of Ⅳ grade neutropenia decreased from 61.54% (40/65) in the screening cycle to 16.92% (11/65) , 18.46% (12/65) and 20.75% (11/53) in 1-3 cycles, respectively. The incidences of FN decreased from 16.92% (11/65) in the screening cycle to 1.54% (1/65) , 4.62% (3/65) , 3.77% (2/53) in 1-3 cycles, respectively. ③The proportion of patients who received antibiotic therapy during the whole period of chemotherapy was 34.39% (141/410) . ④The incidence of adverse events associated with PEG-rhG-CSF was 4.63% (19/410) . The most common adverse events were bone pain[3.90% (16/410) ], fatigue (0.49%) and fever (0.24%) . Conclusion During the chemotherapy in patients with lymphoma, the prophylactic use of PEG-rhG-CSF could effectively reduce the incidences of grade Ⅲ/Ⅳ neutropenia and FN, which ensures that patients with lymphoma receive standard-dose chemotherapy to improve its cure rate.

Objective To observe the influence of nursing intervention on postpartum depression and breastfeeding compliance in primipara.Methods From August 2013 to April 2015,146 women received cesarean section in North Jiaochang Branch of Hanzhong Central Hospital were randomly divided into intervention group and control group with 73 cases in each group.The control group was treated with routine nursing measures,and the intervention group with both routine care and nursing intervention.Self-Rating Depression Scale (SDS) and Self-Rating Anxiety Scale (SAS) were used to evaluate the negative emotions of maternal postpartum.Breastfeeding Self-Efficacy Scale (BSES) were used to evaluate the confidence of maternal breast feeding.The breast feeding compliance between the two groups was compared.The breast feeding rates of the two groups were compared in 1 week and 1 month after discharge.Results Compared with the control group,the SDS and SAS scores of the intervention group were significantly lower (P＜0.05).The breastfeeding confidence of the intervention group was significantly better than the control group and the difference was statistically significant (P＜0.05).The compliance of breast feeding of the intervention group was 97.26％ significantly higher than that of the control group (78.08％)with a statistically significant difference (P＜0.05).After one-week and one-month follow-up,the rate of breastfeeding of the intervention group was significantly higher than that of the control group (95.89％ VS 83.56％;91.78％ VS 72.60％,P＜0.05).Concltsion The nursing intervention measures for primipara after cesarean section can significantly break bad mood,enhance maternal breastfeeding confidence,increase the rate of breastfeeding compliance and are worthy of promotion.

The present study aimed at investigating the possible effects of β-elemene on the progression of atherosclerosis in a rabbit model. The rabbit atherosclerosis model was established by the combination of balloon angioplasty-induced endothelial injury and an atherogenic diet fed to the rabbits. New Zealand White rabbits were randomly divided into four groups (8/group): the normal control group (fed with normal chow diet), and three experimental groups, placebo group, atorvastatin group, and β-elemene group (received the atherogenic diet). After two weeks on the diet, the three experimental groups underwent balloon injury at right common carotid artery and were treated with drugs or placebo for five weeks. Serum lipids were measured. Carotid artery lesions were isolated for histological and immunohistochemical analysis. In vitro, RAW264.7 macrophages were pretreated with β-elemene and ox-LDL for 24 h and the viability of macrophages was assayed using the MTT method. TNF-α and IL-6 were also determined. Compared with the control group, the thickness of the atherosclerosis lesion in the placebo group was significantly increased; The thickness the drug treatment groups were significantly decreased, compared with that of the placebo group. The infiltration of macrophage was markedly reduced in the β-elemene group compared with that of the placebo group. β-elemene treatment also reduced the levels of TC, TG, and LDL-C, compared with the placebo group. β-elemene decreased the TNF-α and IL-6 levels in vitro. In conclusion, our results demonstrated that β-elemene retarded the progression of atherosclerosis in vivo and in vitro, which may be related to the capacity of β-elemene to reduce the infiltration of macrophages and suppress inflammatory factors.

OBJECTIVETo analyze the measles immunity level of persistent population in Beijing.

METHODSA total of 2125 objects from 10 age groups, who had been living in Beijing for over 6 months, were selected from urban and rural areas in Beijing in 2012. Demographic characteristics, history of measles and vaccine immunization were investigated by questionnaire. 5 ml blood sample of each subject was collected, and the Measles IgG antibody was measured by ELISA assay.

RESULTSPositive rate of measles antibody was 84.71% (1800/2125) and standardized positive rate was 88.07% . Median of antibody was 960.46 IU/L. Positive rate and median of measles antibody were significantly different between population from different age groups (χ(2) = 341.60, P < 0.01; H = 216.27, P < 0.01). Antibody positive rate and median were lowest in the <1 year age group, which were separately 43.06% (90/209) and 185.80 IU/L; and highest in the 1-4 (97.31% (181/186) and 2448.81 IU/L) and 5-9 years age group (96.46% (218/226) and 1910.72 IU/L). The range of antibody positive rate and median in adults of ≥ 15 years were 81.98%-90.14% and 744.38-1474.84 IU/L. Antibody positive rate and median in persistent population, which were separately 82.45% (883/1071) and 899.82 IU/L, were lower than those in migrant population, which were 87.00% (917/1054) and 166.19 IU/L, respectively (χ(2) = 8.51, P < 0.01;U = 538 704.00, P < 0.01). Antibody positive rate and median in population with vaccination history, which were separately 91.95% (891/969) and 1443.11 IU/L, were higher than those population without vaccination history and people whose history unknown (32.95% (57/173) , 127.33 IU/L; 86.67% (852/983) , 923.73 IU/L). The difference showed statistical significance (χ(2) = 399.92, P < 0.01; H = 202.11, P < 0.01).

CONCLUSIONAmong the persistent population in China, measles antibody level among the children aging 1-9 years old was high enough to prevent outbreak and epidemic of measles. However, we should try our best to strengthen the measles antibody level among the babies younger than 1 year old and the migrant population aging between 15 and 40 years old.
