ObjectiveTo explore the effect of home visit based on empowerment education on psychotic symptoms, self-management ability and well-being of schizophrenia patients in home rehabilitation. MethodsA total of 87 cases of schizophrenia patients who met the diagnostic criteria of International Classification of Diseases, tenth edition (ICD-10) and were recovering at home in Caiba town, Yibin city from January to July 2021 were selected by random sampling method as research subjects. They were divided into experimental group (n=43) and control group (n=44) according to the random number table method. The two groups received routine family visits, and the experimental group received family visits based on empowerment education. The intervention cycle of the two groups was 6 months. Before and after the intervention, the severity of psychotic symptoms, self-management ability and well-being of the patients in the two groups were assessed with the Brief Psychiatric Rating Scale (BPRS), the Schizophrenia Self-Management Instrument Scale (SSMIS) and the Index of Well-Being Scale (IWB). ResultsAfter intervention, the intra group comparison showed that the BPRS score in the experimental group was lower than that before the intervention (t=4.550, P<0.01), the SSMIS scores in both groups were higher than those before intervention (t=-17.107, -6.367, P<0.01), and the IWB score in the experimental group was higher than that before intervention (t=-9.239, P<0.01). The comparison between groups showed that the BPRS score of the experimental group was lower than that of the control group, and the SSMIS and IWB scores were higher than those of the control group (t=-3.899, 10.564, 9.690, P<0.01). ConclusionThe implementation of family visit based on empowerment education may help to improve the psychotic symptoms of home rehabilitation schizophrenia, and improve their self-management ability and well-being.

Chinese Journal of Child Health Care 2024;32(4):445-450
【Objective】 To explore the correlation of serum vitamin D level of children aged 0 to 3 years with their caregivers′ nutritional knowledge, attitude and practice (KAP) in Yibin, in order to provide reference for the prevention of vitamin D deficiency in children. 【Methods】 A total of 783 children aged 0 to 3 years who underwent child health care at the First People′s Hospital of Yibin from January to December 2020 were selected into this study. Children′s general conditions (feeding, growth and development, lifestyle, etc.) were collected, and venous blood samples were taken to detect serum 25-(OH)D concentration using the chemiluminescence method. The caregivers′ nutritional KAP was investigated using a self-designed knowledge-attitude-practice questionnaire. The relationship between the children′s vitamin D nutritional status and their caregivers′ nutritional KAP was analyzed using pearson correlation analysis. 【Results】 1) The exclusive breastfeeding rate of children aged 0 to 3 years was about 62.2%. Significant differences were found in outdoor activity time and average vitamin D supplementation among different age groups (t=9.030, 10.260, P<0.05). 2) The average concentration of serum 25-(OH)D was (36.8±8.7)ng/mL, and the incidence of vitamin D deficiency was 21.84%. Significant differences were found in serum 25-(OH)D level and the incidence of vitamin D deficiency among children of different ages, body shapes, outdoor activities, and vitamin D supplementation (t/F: 2.220 - 6.302, χ2: 5.346 - 33.134, P<0.05). 3) The caregivers′ nutritional KAP scores were 78.9±9.9, 88.1±8.3, and 78.3±11.8, respectively, with parents scoring higher than other caregivers (P<0.05). 4) Serum 25-(OH)D level was positively correlated with the nutritional knowledge, attitude, and behavior scores of caregivers (r=0.805, 0.650, 0.831, P<0.05). The caregivers′ nutritional KAP grade was correlated with vitamin D deficiency (P<0.05). 5) Overweight/obesity was a possible risk factor for vitamin D deficiency in children (OR=2.126, 95%CI: 1.162 - 3.887). Outdoor activity duration ≥2h/d (OR=0.592, 95%CI: 0.392 - 0.895), regular vitamin D supplementation (OR=0.618, 95%CI: 0.456 - 0.838), and good nutritional behavior of caregivers(OR=0.725, 95%CI: 0.563 - 0.933) were protective factors for vitamin D deficiency in children (P<0.05). 【Conclusions】 The prevalence of vitamin D deficiency is high among children aged 0 to 3 years in Yibin, and it is related to the nutritional KAP of their caregivers. Improving the nutritional KAP of caregivers can help prevent and manage vitamin D deficiency in children.

Totally, 125 elderly inpatients with aspiration pneumonia (AP) were enrolled from departments of respiratory medicine and neurology at Zhongnan Hospital, Wuhan during June 2005 to October 2009 for analysis. Results showed that listlessness was manifested in 70 cases (56%), primary neurological illness in 80 cases (64%), 57 of them (46%) complicated with respiratory failure and 26 died with case-fatality of 21%. Main pathogen for them was Gram-negative bacillus, accounting for 57% of the total. Two kinds or more of antibiotics had ever been administered in 98 cases (78%), with an average length of antibiotics use for 28 days, ranging from one day to 128 days. Nasal feeding was instituted for those with choking over their feeding and coughing, and their inspired feeding was aspirated from the trachea or bronchi and lavished with bronchoscopy, with 38 cases by tracheal intubation, 26 by tracheotomy and 42 with artificial ventilation. Their average duration of hospital stay spanned 28 days with an average cost of 25 000 RMB yuan per capita, significantly higher than that for those with common pneumonia. In conclusion, clinical features of these elderly patients with AP were not so typical, most of them manifest severe, with lots of medical cost and bad prognosis.

To investigate effects of tumor necrosis factor-alpha(TNF-alpha) and granulocyte-colony stimulation factor(G-CSF) on the transplantation rate of rabbit mesenchymal stem cells (MSCs) through intracoronary injection. Japanese white ears rabbits (2-3 months old) were used as myocardial injury models by intravenously injecting adriamycin, then they were divided into three groups randomly: (1) Blank group, (2) TNF-alpha group; (3) G-CSF group. There were 7 rabbits each group. Before transplantation, MSCs and rabbit models were neither intervened by cytokine in blank group; in TNF-alpha group, rabbits were injected TNF-alpha (5 microg/kg) through ear-edge vein one day before transplantation, MSCs were pretreated by TNF-alpha (10ng/ml)12 hours before transplantation. In G-CSF group, rabbits were injected G-CSF(10 microg/kg) intramuscular each day 3 days before transplantation. MSCs were pretreated by G-CSF(10 ng/ ml) 12 hours before transplantation. Separated by density gradient centrifugation and labeled by 4,6-biamidine-2-phenyliodole (DAPI) after cells expanded in vitro, MSCs were then transplanted through the root of aorta when the ascending aorta occluded above the sinus aortae. Myocardial pathological sections were made after 4 weeks and count transplanted cells under laser scanning confocal microscope and statiscally analyze. The amount of cells transplanted in rabbit myocardial were much more in TNF-alpha group G-CSF group than in blank group, there was statistically significant difference (P < 0.001). It sugested that TNF-alpha and G-CSF intervened the cultured MSCs, and animal model of myocardial injury could elevate the transplantation rate of intracoronary injection rabbit mesenchymal stem cells. The mechanism may have relation to that cytokine can enhance the attachment of MSCs to cardiac microvascular endothelium (CMVE).

Chinese Journal of Gastrointestinal Surgery 2015;18(12):1253-1255
OBJECTIVETo discuss the clinical characteristics of remnant gastric cancer (RGC).
METHODSClinical data of 163 patients with RGC admitted to our department from January 2005 to January 2015 were collected and reviewed.
RESULTSThe time duration of all the RGC patients between primary gastrectomy and occurrence of RGC ranged from 9 to 46 years (median 27.5 years). Among 163 patients, 112(68.7%) patients manifested as discomfort in the upper abdominal region, 47(28.8%) patients had hematemesis and melena, 38(23.3%) had vomiting, 17(10.4%) had swallowing difficulty and 12 (7.4%) had decreased weights. In pathology, 127 (77.9%) cases were median or low grade adenocarcinoma; 114(69.8%) patients were Borrmann type III( gastric cancer under endoscope; 145 (88.9%) patients were TNM III(-IIII( gastric cancer. A total of 106 patients underwent operation, including 75(70.8%) patients of radical resection and 31(29.3%) patients of palliative resection. Patients mainly received Billroth II( anastomosis (77.4%) as digestive tract reconstruction, while 57 cases did not receive surgical operation. The overall 1-, 3-, and 5-year survival rates of the patients were 76.1%, 43.4%, 25.8% respectively. The median survival time of patients receiving radical resection and those receiving palliative resection was 34.6 months and 16.4 months respectively, whereas patients who did not receive surgical operation died 3-8 months after initial diagnosis.
CONCLUSIONSRegular gastroscopy is necessary for patients undergoing gastrectomy for over 10 years. Radical resection is of great importance in the treatment of remnant gastric cancer.
