Objective:To systematically evaluate and integrate the qualitative research of nursing students participating in hospice care practice experience, to provide a basis for the better development of hospice care education.Methods:A computer search was conducted on the China national knowledge infrastructure, Chinese Biomedical Literature Database, VIP database, Wanfang Medical Database, Cochrane Library, Embase, Web of Science, and PubMed for qualitative research on nursing students' participation in hospice care practices. The search period was from the establishment of the database to February 2023. The quality of the included literature was evaluated using the qualitative research quality evaluation criteria of the Australian JBI Evidence Based Health Care Center. A aggregative integration method was used for result integration.Results:A total of 16 articles were included, and 46 major research results were extracted and summarized into 9 new categories, forming 4 integrated results: providing hospice care services for patients and their families; emotional experience of nursing dying patients; coping with negative experience and harvesting personal growth; needs and difficulties.Conclusions:Nursing students experience multiple emotional experiences in hospice care practice, and are eager to help and support in various aspects. It is suggested for managers to pay attention to the inner experience and needs of nursing students, improve hospice care education in China, and improve the end-of-life care ability of nursing students.

Objective To explore the affective response and dynamic attributes of obese adolescents in high-and moderate-intensity interval training.Methods Between February and July 2023,a total of 42 obese adolescents(Age:12.3±0.5 years,BMI:24.0±1.1 kg/m2)were recruited and randomly divided into a high-intensity interval training group(HIIT),a moderate-intensity interval training group(MIIT),and a non-training control group.Before and after the intervention,all groups were measured and compared their weight,BMI,body composition(body fat percentage and visceral adipose fat),car-diorespiratory fitness(VO2max),and affective response during exercise(affect valence,perceived arousal,rating of perceived exertion),as well as post-exercise enjoyment.Results After the 12-week interven-tion,there were significant decrease in the average BMI,body fat percentage,and visceral adipose tis-sue in the HIIT group(P<0.05),but a significant increase in the average VO2max(P<0.05).Moreover,a-fter the training,the average VO2max of the HIIT group was significantly higher than the MIIT group(P<0.05).Meanwhile,both HIIT and MIIT had a positive effect on emotional valence and post-exercise enjoyment.However,MIIT participants had more positive affect responses than HIIT ones,while the arousal(P<0.01)and physical activity enjoyment scores(P<0.05)in the HIIT group were significantly higher than the MIIT group.Conclusions Interval training is effective in improving body composition and cardiorespiratory fitness of obese adolescents.Higher intensity and arousal are key to the improve-ment.Moreover,the positive affect response and exercise enjoyment after interval training may help them maintain high exercise adherence and play a long-term promoting role.

Objective:To compare and analyze the technical success rate and safety between computed tomography(CT)-percutaneous radiological gastrostomy (PRG) and percutaneous endoscopic gastrostomy (PEG).Methods:From January 2017 to January 2022, at the First Affiliated Hospital of Zhengzhou University, the data of 76 patients who underwent gastrostomy due to inability to eat orally were collected, including 38 patients in PEG group and 38 patients in CT-PRG group. Surgical outcomes and complications were compared between the PEG and CT-PRG groups. Surgical outcomes included technical success rate, operation time, postoperative body mass index and hospital stay; while complications included minor complications (such as perifistula infection, granulation tissue proliferation, leakage, pneumoperitoneum, fistula tube obstruction, fistula tube detachment and persistent pain) and serious complications (such as bleeding, peritonitis, colonic perforation and death within 30 d). Independent sample t test, chi-square test, and Fisher exact probability test were used for statistical analysis. Results:The technical success rate of CT-PRG group was higher than that of the PEG group (100.0%, 38/38 vs. 78.9%, 30/38), and the operation time was shorter than that of the PEG group ((17.16±8.52) min vs. (29.33±16.22) min), and the differences were statistically significant ( χ2=1.19, t=2.36; P=0.038 and 0.011). There were no significant differences in postoperative body mass index ((16.29±3.56) kg/m 2 vs. (16.12±3.17) kg/m 2) and hospital stay ((4.13±1.26) d vs. (3.52±1.13) d) between PEG group and CT-PRG group (both P>0.05). The incidence of minor complications in the PEG group was 42.1% (16/38), including 6 cases of perifistulal infection, 1 case of leakage, 5 cases of fistula tube obstruction, 1 case of fistula tube detachment, and 3 cases of persistent pain. The incidence of serious complications was 5.3% (2/38), including 1 case of bleeding and 1 case of colonic perforation. The incidence of minor complications in the CT-PRG group was 39.5% (15/38), including 5 cases of perifistula infection, 1 case of granulation tissue proliferation, 3 cases of pneumoperitoneum, 3 cases of fistula tube obstruction, 2 cases of fistula tube detachment, and 1 case of persistent pain. The incidence of serious complications was 0. There was no significant difference in the incidence of minor complications between the PEG group and the CT-PRG group ( P>0.05), while the incidence of serious complications in the CT-PRG group was lower than that of the PEG group, and the difference was statistically significant (Fisher exact probability test, P=0.043). Conclusion:PEG is a safe and effective method of gastrostomy, but for patients with esophageal obstruction, CT-PRG can be an effective supplement to PEG.

Cystatin, a cysteine protease inhibitor found in many parasites, plays important roles in immune evasion. This study analyzed the molecular characteristics of a cystatin from Fasciola hepatica (FhCystatin) and expressed recombinant FhCystatin (rFhcystatin) to investigate the immune modulatory effects on lipopolysaccharide-induced proliferation, migration, cytokine secretion, nitric oxide (NO) production, and apoptosis in mouse macrophages. The FhCystatin gene encoded 116 amino acids and contained a conserved cystatin-like domain. rFhCystatin significantly inhibited the activity of cathepsin B. rFhCystatin bound to the surface of mouse RAW264.7 cells, significantly inhibited cell proliferation and promoted apoptosis. Moreover, rFhCystatin inhibited the expression of cellular nitric oxide, interleukin-6, and tumor necrosis factor-α, and promoted the expression of transforming growth factor-β and interleukin-10. These results showed that FhCystatin played an important role in regulating the activity of mouse macrophages. Our findings provide new insights into mechanisms underlying the immune evasion and contribute to the exploration of potential targets for the development of new drug to control F. hepatica infection.

Objective:To observe the effects of T-2 toxin on expression of hepatocyte growth factor (HGF) and HGF receptor (C-Met) in articular cartilage and epiphyseal cartilage of rats under low selenium condition.Methods:Twenty-four healthy male SD rats weighted 60-80 g were randomly divided into conventional diet group (selenium content of 101.5 μg/kg) and low-selenium diet group (selenium content of 1.1 μg/kg), with 12 rats in each group. After 30 days of feeding, the conventional diet group was further divided into conventional group and T-2 toxin group (100 μg·kg -1·d -1), and the low-selenium diet group was further divided into low-selenium group and low-selenium+T-2 toxin group (100 μg·kg -1·d -1), with 6 rats in each group. After 30 days of feeding, the rats were sacrificed and the cartilage of knee joint was taken, the morphological changes of knee articular cartilage and epiphyseal cartilage were observed by HE staining under light microscope. Immunohistochemical method was used to detect the expression of HGF and C-Met in knee articular cartilage and epiphyseal cartilage, and positive expression rates of HGF and C-Met were calculated. Results:Under light microscope, chondrocytes of articular cartilage and epiphyseal cartilage in low-selenium+T-2 toxin group were sparse, and the necrosis and structural area were found in the deep layer, and the extracellular matrix of chondrocytes in the region was degraded and light stained, and proliferating granulation tissue was visible nearby. The positive expression rates of HGF in articular cartilage [(21.97 ± 6.90)%, (49.41 ± 8.24)%, (76.39 ± 5.88)%] and epiphyseal cartilage [(23.36 ± 12.49)%, (58.43 ± 14.48)%, (66.59 ± 10.83)%] of rats in low-selenium, T-2 toxin and low-selenium+T-2 toxin groups were higher than those in conventional group [(9.13 ± 6.01)%, (11.14 ± 4.67)%, P < 0.05]. The positive expression rates of C-Met in articular cartilage [(25.34 ± 7.53)%, (58.21 ± 12.54)%, (81.46 ± 7.89)%] and epiphyseal cartilage [(35.21 ± 4.71)%, (40.84 ± 2.03)%, (49.41 ± 6.29)%] of rats in low-selenium, T-2 toxin and low-selenium+T-2 toxin groups were higher than those in conventional group [(11.21 ± 5.11)%, (12.12 ± 4.71)%, P < 0.05]. Conclusion:T-2 toxin may affect the expression of HGF and C-Met in articular cartilage and epiphyseal cartilage of rats under low selenium condition.

Conclusion The high economic burden of disease of norovirus gastroenteritis in the Pearl River Delta Region, respectively, indicating that relevant departments should strengthen the prevention, control and education in order to mitigate the disease economic burden.

BACKGROUND:Valgus-varus constrained polyethylene insert is selected in strict accordance with the principle of“to obtain reliable stability using minimum restriction”. The stability of the prosthesis is elevated, but the restriction is not increased.
OBJECTIVE:To retrospectively analyze the application experience of constrained polyethylene insert in valgus and varus instability of primary total knee arthroplasty for older patients and to summarize the indications and clinical effects of this kind of implements.
METHODS:From March 2010 to March 2012, a total of 70 patients combined valgus and varus malfomation who accepted primary total knee arthroplasty were enrol ed in this study, including 56 varus patients (averagely 15°-30°) and 14 valgus patients (averagely 10°-20°). Constrained polyethylene insert was performed in 23 patients (25 knees) who stil had remaining unilateral valgus or varus<6 mm (18 patients were varus instability and 7 patients were valgus instability) when finished operation of standard osteotomy and soft tissue balancing. The bone cement knee prostheses in 23 cases were purchased from Smith&Nephew. The stem implant was not used in al cases. Cement or autografts were used in 11 valgus knees to fil the bone defects.
RESULTS AND CONCLUSION:Patients were fol owed up for 2 years on average (18-42 mouths). The knee pain symptoms of al cases disappeared. The joint stability was obviously improved. The lower limb power lines were correct. The Knee Society Score scores were improved from an average of 39.4 points preoperation to an average of 88.5 points postoperation. Al cases did not need the protection of knee braces. The maximum degree of flexion was 110°(96°-130°). The satisfaction degree of 36-Item Short Form Health Survey was 98%. No dislocation or infection happened. Results indicated that constrained polyethylene insert could be applied in the cases of less than 6 mm valgus and varus instability when finished operation of standard osteotomy and soft tissue balancing in total knee arthroplasty for older patients. This kind of implements can preserve bone mass, simplify operational process and have good clinical outcome in a short period.

OBJECTIVE: To evaluate the clinical effectiveness and safety of Sanchi Tong Shu capsule in the treatment of common aural vertigo. METHOD: A multi-center randomized controlled trial was designed to study 206 vertigo patients who were randomly allocated into one of the two groups. One group was treated with Sanchi Tong Shu capsule for 14 days, another group was treated with betahistine mesilate tablets for 14 days. RESULT: The clinical effectiveness rates of the two groups were 84.86% and 90.92% respectively according to FAS analysis and 84.76%, 90.92% respectively according to PPS analysis. No statistic significance difference was found between the two groups (P > 0.05). After 14 days treatment, total DHI and all the subsection (including body, emotion and function) scores of the two groups were all decreased compared with treatment before (P < 0.01). Compared the difference value of the total DHI and subsection scores before and after treatment, the two groups have no difference (P > 0.05). The adverse effective rate of the two groups were 3.29% and 7.84% respectively and there was no statistic difference between the two groups (P > 0.05). CONCLUSION Sanchi Tong Shu capsule is a safe and effective drug for the treatment of common aural vertigo.
