Objective To investigate curative efficacy of tetramethylpyrazine in combination with chemotherapy in treatment of medium and advanced liver cancer and its effects on level of brain-derived neurotrophic factor ( BDNF).Methods 90 patients of medium and advanced liver cancer who received therapy from January 2011 to June 2012 were selected as research objects.According to therapeutic schemes, those patients were divided into the control group (n=42) and the observation group (n=48).The control group was treated with transcatheter hepatic arterial chemoembolization ( TACE) , while the observation group was treated with tetramethylpyrazine in combination with TACE.Then, the short-term curative efficacy, long-term curative efficacy, level of BDNF and adverse reactions were compared.Results The total short-term therapeutic efficacy ratio in the observation group was statistically higher than that in the control group ( 83.3% vs 64.3%, P <0.05 ).During the three-year follow-up, the one-year and two-year survival rate in the observation group was statistically same with that in the control group respectively (75.0% vs 66.7%, 66.7% vs 59.5%), while the three-year survival rate was statistically higher than that in the control group (52.1%vs 30.9%, P<0.05).After treatment, in comparison with the control group, level of BDNF in the observation group was statistically lower(P<0.05).During treatment, incidences of liver function deterioration, abdo minal pain and diarrhea, nausea and vomiting, fever and headache in two groups were statistically same.Conclusion Tetramethylpyrazine in combination with TACE is effective for medium and advanced liver cancer, which can increase short-term and survival rate to some extent, significantly reduce level of BDNF with not increasing incidence of adverse reactions.

With the mutual communication and penetration of traditional Chinese medicine and modem medicine,the combination of traditional Chinese and western medicine is common in clinical practice.However,since western-style doctor is usually lack of traditional Chinese medicine theory knowledge,many problems exist in the combination of Chinese and western medicine.The problem that Chinese medicine containing ephedra alkaloids in combination with western medicine in pediatric medicine is especially serious.Because of the complexity of the children's drugs,improper use of the ephedra alkaloids is prone to adverse reactions.A comprehensive analysis of drugs containing ephedra alkaloids existing in the pediatric clinical application is performed,and in order to provide guidance for clinical rational drug use.

Objective: To investigate the prevalence of work-related musculoskeletal disorders(WMSDs) among intensive care unit (ICU) nurses, assess its relationship with ergonomic load and overall exposure levels. Methods: A total of 272 ICU nurses from two tertiary hospitals in a city were selected as the research subjects using convenient sampling method. The Chinese Musculoskeletal Disorder Questionnaire was used to investigate the prevalence of WMSDs among the ICU nurses. The Quick Exposure Check (QEC) was used to assess the ergonomic load on the back, shoulder/arm, hand/wrist, and neck during different clinical nursing operations. Results: The annual prevalence of WMSDs was 75.7% among ICU nurses. The annual prevalence of WMSDs in different body parts, from high to low, was as follows： lower back, neck, shoulder/arm, back, knee, hip/leg, hand/wrist, ankle/foot, and elbow (54.8% vs 43.4% vs 40.8% vs 36.0% vs 21.3% vs 19.9% vs 18.8% vs 18.4% vs 8.1%, P<0.01). ICU nurses had the highest QEC scores on the back (dynamic), shoulder/arm, hand/wrist, and neck with assisting patient turning (all P<0.05) among the six clinical nursing items. During the operation of patient turning, patient lifting, patient bathing, and bed sheet changing for bedridden patients, the back (dynamic) and shoulder/arm were at a high load level, while the hand/wrist and neck were at a mild load level. When nurses were providing tracheostomy care and oral care for intubated patients, their back (static), shoulder/arm, hand/wrist, and neck were at a mild load level. The overall exposure rate for assisting patient turning, patient lifting, oral care for intubated patients, bed sheet changing for bedridden patients, patient bathing, and tracheostomy care were 77.8%, 66.5%, 63.6%, 60.2%, 58.5%, and 57.4%, respectively. The risk for assisting patient turning was classified as level four, while the risk for other clinical nursing items was level three. Conclusion: The prevalence of WMSDs in ICU nurses is high. Both ergonomic load level and total exposure rate of back, shoulder/arm, hand/wrist and neck were high during clinical nursing operations.

Objective To explore the role and mechanism of thymosin β4 (Tβ4) in the treatment of non-alcoholic fatty liver disease (NAFLD).Methods Forty male C57BL/J6 mice were divided into normal group,NAFLD group,low dose Tβ4 group and high dose Tβ4 group with 10 mice in each group.NAFLD mice model was established by feeding with high fat and high sugar diet for 16 weeks.The mice in low-dose Tβ4 group and high dose Tβ4 group were intraperitonealy injected with Tβ4 at 0.05 mg · kg-1 · d-1 and 0.20 mg · kg-1 · d-1,respectively,for eight weeks.The liver function indexes and serum tumor necrosis factor-α (TNF-α) level were detected;the pathological changes of liver tissue were observed under optical microscope and non-alcoholic fatty liver disease activity score (NAS) was evaluated.The protein expression levels of nuclear factor-κB p65 (NF-κB p65) and nuclear factor κB inhibit protein a (IκBa) at the protein level in liver tissue were measured by Western blotting method.The expression of TNF-α in liver tissue was detected by immunohistochemistry.Mean integral absorbance (MIA) was calculated.T test was performed for groups comparison.Results The levels of alanine aminotransferase (ALT),γ-glutamine transferase (GGT) and serum TNF-α levels of high dose Tβ4 group were all lower than those of NAFLD group ((28±17) U/L vs.(76±29) U/L,(61±39) U/L vs.(102±56) U/L,(144.1± 48.2) ng/L vs.(187.3±58.8) ng/L,respectively),and the differences were statistically significant (t=4.52,2.78 and 2.30,all P＜0.05).The NAS of low dose Tβ4 group and high dose Tβ4 group were both lower than that of NAFLD group (3.7±40.4,2.3±0.3 vs.4.6±0.3),and the differences were statistically significant (t=5.69 and 17.14,both P＜0.01).The relative expression level of Tβ4 protein of NAFLD group was lower than that of normal group (0.2±0.1 vs.1.4±0.6),and the difference was statistically significant (t=6.24,P＜0.01).The relative expression levels of Tβ4 and IκBa of high dose Tβ4 group were higher than those of NAFLD group (1.0±0.3,0.5±0.3 vs.0.2±0.1),and the differences were statistically significant (t=8.00 and 3.00,both P＜0.01).The relative expression level of NF-κB p65 in liver tissue of high dose Tβ4 group was lower than that of NAFLD group (0.6±0.3 vs.1.5±0.7),and the difference was statistically significant (t=3.74,P＜0.01).The MIA of high dose Tβ4 group was lower than that of NAFLD group (0.4±0.2 vs.0.7±0.3),and the difference was statistically significant (t=2.63,P＜ 0.01).Conclusion Tβ4 can effectively treat NAFLD probably through inhibiting the NF-κB pathway.

Objective:To investigate the current situation and influencing factors of patients′ satisfaction with nursing humanistic care, and to provide reference for improving the quality of such care provided by hospitals.Methods:From July to August 2022, outpatients and inpatients in 30 provinces were selected by multi-stage stratified sampling as the survey objects. A cross-sectional survey was conducted on an online platform, using the general information questionnaire and Chinese version of methodist health care system nurse caring instrument revised by the research group. The latter instrument consists of 12 dimensions. namely care coordination, competence, teaching/learning, emotional support, respect for individuality, physical comfort, availability, helping/trusting relationship, patient/family engagement, physical environment, spiritual environment and outcomes. Descriptive analysis was performed on the data collected by the questionnaires, and independent sample t-test and one-way ANOVA were used to analyze the influencing factors of patient satisfaction. Results:A total of 107 hospitals were selected for questionnaire survey, including 86 tertiary hospitals and 21 secondary hospitals, and 29 108 valid questionnaires were recovered. The patient satisfaction with nursing humanistic care scored (5.40±0.86); the top three dimensions were competence (5.50±0.89), emotional support (5.47±0.88) and helping/trusting relationship (5.46±0.86); the lowest scoring dimensions were teaching/learning (5.38±1.01), spiritual environment (5.36±1.04) and patient/family engagement (5.11±1.28). Differences with gender, age, marital status, child status, educational level, occupation, place of residence, economic region, per capita monthly income of the family, type of medical insurance, medical department visited and surgery or not presented significant differences on the patient satisfaction with nursing humanistic care scores ( P<0.05). Conclusions:The satisfaction of patients with hospital′s nursing humanistic care in China was at the middle to upper level. In the future, health education for patients should be strengthened, and a mode of family-engaged nursing humanistic care should be constructed in line with the Chinese cultural background. In the process of nursing services, the particularity of patient groups should be considered to better meet their needs.

OBJECTIVES: To investigate the status and the related factors of nursing behaviors for pressure injury, and to provide the evidence for standardizing pressure injury management. METHODS: A total of 1 039 clinical nursing staff from 4 general hospitals in Changsha from December 1 to 30, 2017 were selected by a stratified random sampling procedure. Nurses' demographic information such as age, gender, title, educational attainment, and department were collected. We investigated the status of nursing behaviors on pressure injury by a self-designed questionnaire, assessed nurses' knowledge of pressure injury and nurses' attitude of pressure injury using the Pressure Ulcer Knowledge Test and Attitude towards Pressure Ulcer Prevention Instrument, respectively, compared the nursing behaviors on pressure injury with different backgrounds, used multiple linear regression to analyze the influential factors for nursing behaviors on pressure injury, and conducted the Pearson correlation analysis for nurses' knowledge, attitude, and behaviors on the pressure injury. RESULTS: The overall nursing behaviors score on pressure injury was 155.96±17.29. The 5 dimensional scores from high to low were: risk assessment (4.42±0.49), prevention actions (4.40±0.50), risk understanding (4.35±0.52), injury assessment and interventions (4.27±0.55), and health education (4.25±0.63). A significant difference was found in the nursing behavior scores of pressure injury among ages, lengths of service, education, and training times (all ˂0.05). There was no correlation between nurses' knowledge and behaviors (=0.606). The nurses' attitude was positively correlated with their behaviors (=0.307, ˂0.001), and the nurses' knowledge was also positively correlated with their attitudes (=0.212, ˂0.001). The results of multiple linear regression showed that the length of service (≤5 years), training times (1-2 times), education (diploma or below), the scores of nurses' knowledge, and the scores of nurses' attitude were independent influencial factors of nurses' behaviors on pressure injury. CONCLUSIONS The nursing staff in the general hospital of Changsha has a high level of nursing behaviors on pressure injury, and they has good sense of responsibility and confidence. However, personal competence in pressure injury is insufficient and still needs to be improved. The nursing managers should focus on the nurses' attitude and training frequency, increasing the experience in nursing the pressure injury and practical level, and arouse the highly educated nurses' enthusiasm and sense of accomplishment to prevent pressure injury, thus reducing the incidence of pressure injury.

To develop an intervention protocol for children's unintentional injury risk behaviors, and to evaluate the feasibility of the protocol.
 Methods: By theoretically analyzing the influential factors for children's unintentional injury risk behaviors, children's cognitive development characteristics and the social learning theory, an intervention protocol was established on the basis of changing the unintentional injury attribution and negative information transmission of risk behavior consequences. A primary school in Changsha city was selected by random cluster sampling. A community-based randomized controlled trial was conducted on the selected students once a week for 5 consecutive weeks. The scores of unintentional injury risk behavior before intervention, 3 months and 6 months after intervention, and the frequency before intervention and 6 months after intervention, were collected and compared.
 Results: A total of 194 children were included in the study: 98 in the intervention group; 96 in the control group; 96 (49.5%) boys and 98 (50.5%) girls between 7 and 8 years old. The scores of unintentional injury risk behavior for children in the intervention group at 3 and 6 months after intervention were 14.42±5.67 and 14.14±8.95, respectively, lower than those before the intervention (16.85±8.48) and in the control group (P=0.001). The number of minor unintentional injuries in the intervention group decreased from 119 to 56, and the number of children suffering 2 or more injuries dropped from 34 to 10 (P<0.001) at 6 months after the intervention, while both of them were lower than that in the control group (P=0.011). Similar changes were observed in some slight or more serious unintentional injuries (P=0.030).
 Conclusion: The protocol for changing the attribution to unintentional injury and negative information transmission for risk behavior consequences was proved to effectively reduce children's unintentional injury risk behaviors and relevant events.
