Effects of High-flux Hemodialysis With Narrative Care on Clinical Efficacy and Prognostic Quality of Life of Patients With Chronic Renal Failure.

Context: Chronic renal failure (CRF) is the outcome of the continuous progression of various chronic kidney diseases. Effective treatment of a wide range of diseases may require decreasing patients' negative emotions and enhancing their disease resilience. Narrative care focuses on patients' inner awareness, feelings, and experience of a disease, stimulating positive energy in the face of it. Objective: The study intended to investigate the effects of using narrative care during high flux hemodialysis (HFHD) on clinical outcomes and prognosis of quality of life (QoL) for patients with chronic renal failure (CRF), to provide a reliable theoretical reference for future clinical treatment. Design: The research team performed a randomized controlled trial. Setting: The study took place at the Blood Purification Center at the Affiliated Hospital of Medical School at Ningbo University in Ningbo, Zhejiang, China. Participants: Participants were 78 patients with CRF who received treat with HFHD at the hospital between January 2021 and August 2022. Intervention: The research team divided participants into two groups using the random number table method, with 39 participants in each group: (1) and intervention group who received narrative nursing care and (2) a control group who receive the usual care. Outcome Measures: The research team: (1) evaluated the clinical efficacy for both groups; (2) at baseline and postintervention, measured participants' blood creatinine (SCr) and blood urea nitrogen (BUN) using blood sampling; (3) counted adverse effects; (4) investigated participants' nursing satisfaction postintervention; (5) at baseline and postintervention, assessed psychology and QoL using the Self-Assessment Scale for Anxiety (SAS), the Self-Assessment Scale for Depression (SDS), and the General Quality of Life Inventory (GQOLI-74) scale. Results: No statistically significant differences existed between the groups in terms of efficacy or renal function postintervention (P > .05). The incidence of adverse reactions was significantly lower in the intervention group than in the control group postintervention (P = .033), and the group's nursing satisfaction was significantly higher (P = .042). In addition, participants' SAS and SDS scores decreased significantly in the intervention group postintervention (P < .05), while no change occurred for the control group (P > .05). Finally, the GQOLI-74 scores were all significantly higher in the intervention group than in the control group. Conclusions: Narrative care can effectively enhance the safety of HFHD treatment in CRF patients and reduce patients' negative emotions postintervention, which is important for improving their QoL.

Impacts of Acupuncture Plus Acupoint Application on Intestinal Function and Expression of MAPK and ERK in Colon Tissue of Rats.

Context: Slow transit constipation (STC) has a high incidence worldwide, which not only seriously affects patients' normal lives but also may cause malignant intestinal lesions. Among the limited treatment options for STC, traditional Chinese medicine (TCM) is considered to be the key to STC treatment in the future. Objective: The study intended to examine the impacts of acupuncture plus acupoint application on MAPK and ERK in STC rats, with the aim of preliminarily exploring the relevant mechanisms for treating STC as well as providing new ideas and means for future clinical treatment. Design: The research team designed a randomized, controlled animal study. Setting: The study was carried out at department of Department of Rehabilitation, Affiliated Hospital of Medical School of Ningbo University, Ningbo, Zhejiang, China. Animals: The animals were 30 six-to-eight-week-old, Sprague Dawley (SD) rats, half male and half female and weighing a mean of 200 ± 20 g. Intervention: The rats were randomly assigned to one of three groups, 10 rats in each group: a negative control group that wasn't induced with STC and received no treatments; a positive control group, the model group (MG), that was induced with STC and received no treatments; and an intervention group that was induced with STC and received the investigated treatments. The intervention group was treated with acupuncture at Tianshu point (ST25) and received acupoint application from Chinese medicine. Outcome Measures: The study measured the alterations in the rats' body weight and feces, as well as the rats' intestinal motility, using intragastric administration of activated carbon. The rats were killed to obtain their intestinal tissues, for measuring expression of mitogen-activated protein kinase (MAPK) and extracellular signal-regulated kinase (ERK) using Western blotting and polymerase chain reaction (PCR). Results: Postintervention, at 28 days after induction of STC, the rats' weights weren't significantly different in the intervention and control groups (P > .05) but were significantly higher than that in the model group (P < .05). The rats' weights in the intervention and control groups gradually increased significantly, while those in the model group gradually decreased significantly (P < .05). The defecation volume and fecal water content (FWS) decreased in the significantly model group but increased significantly in the intervention group (P < .05). The intestinal motility test revealed no significant differences in the propulsion rate between the intervention and control groups (P > .05), but the rate was significantly lower in the model group than that of the intervention group (P < .05). The intestinal fecal residue in the model group was the highest among the three groups, followed in descending order by the intervention group and the control group, with the differences being statistically significant (P < .05). In addition, the MAPK and ERK in the model group significantly increased, and the values were significantly higher in the intervention group than those of the model group (P < .05). Conclusions: Acupuncture plus acupoint application can validly improve the defecation and intestinal motility of STC rats, possibly through inhibiting MAPK and ERK.

Selenium level surveillance for the year 2007 of Keshan disease in endemic areas and analysis on surveillance results between 2003 and 2007.

Selenium deficiency is widely accepted as a fundamental cause of Keshan disease (KD). In the present study, the selenium levels of hair and food samples of KD in some endemic areas were measured; the prevalence and incidence of KD for the year 2007 in these areas were surveyed. The results for KD surveillance from 2003 to 2007 were analyzed. The selenium level was measured fluorometrically. In 2007, a total of 19,280 residents were surveyed in 15 provinces. The prevalence and incidence of KD were 3.0% and 4.9‰, respectively. In KD and control subjects, the mean levels of hair selenium were respectively 0.3223 mg/kg and 0.4466 mg/kg. The mean level of staple food selenium was 0.0227 ± 0.0144 mg/kg. During the 5 years, the selenium content in hair was always kept at a normal level within inhabitants of KD-endemic areas, but that in staple food was always kept at a lower level. These results indicate that the pathogenic factor has not been drastically eliminated even with the increasing selenium level of internal environment and is still continually damaging public health of KD in endemic areas. Since KD is still a serious threat to public health in its endemic areas, it is of great importance to pay attention to the prevention and control of this disease.
