Acute-on-chronic liver failure （ACLF） is a syndrome of multiple organ failure on the basis of underlying chronic liver disease and has an extremely high short-term mortality rate， while there is still a lack of unified diagnostic criteria around the world. Radiology plays an important role in the evaluation and prognostic prediction of ACLF， constituting a multi-dimensional assessment system covering morphology， function， and hemodynamics. Computed tomography can be used for the measurement of liver volume and the diagnosis of sarcopenia by providing key morphological and nutritional parameters. Magnetic resonance imaging （MRI）， especially gadobenate dimeglumine-enhanced MRI， enables quantitative assessment of liver function and has critical significance for predicting short-term survival rate. Ultrasonography and elastography techniques facilitate the early warning of ACLF onset and the dynamic monitoring of its progression through noninvasive measurement of liver stiffness and hemodynamic parameters. This article systematically reviews the pivotal role of these three imaging modalities in the diagnosis and monitoring of ACLF， and integrating the strengths of multiple imaging techniques with clinical indicators to construct diagnostic and prognostic models may become a key future direction for achieving early intervention and improving clinical outcomes in ACLF.

Objective:To evaluate the quality of life in patients with psoriasis across varying levels of psychological resilience.Methods:A cross-sectional study was conducted, employing a convenient sampling method to recruit 390 psoriasis patients from Beijing University of Chinese Medicine Dongzhimen Hospital from February to August 2023. The sample included 57 male and 333 female patients, with a mean age of (24.9±5.4) years. Participants were guided through questionnaire completion using a standardized protocol by trained investigators. Patients were stratified into three groups based on the Connor-Davidson Resilience Scale (CD-RISC-10): low ( n=53), moderate ( n=251), and high ( n=86) psychological resilience. The dermatology life quality index (DLQI) was utilized to assess quality of life across six domains: symptom perception, daily activities, leisure and recreation, work and study, interpersonal relationships, and treatment. Results:The total scores for the DLQI among psoriasis patients with low, moderate, and high psychological resilience were 10.05 (6.75, 15.00), 7.00 (4.00, 11.00), and 5.00 (2.00, 10.00), respectively. Symptom perception scores were 3.00 (2.00, 4.00), 2.00 (2.00, 4.00), and 2.00 (1.00, 3.00), respectively. Scores for daily activities were 2.00 (2.00, 4.00), 1.00 (1.00, 2.00), and 1.00 (0.00, 2.00), respectively. Leisure and recreation scores were 2.00 (1.00, 3.00), 1.00 (0.00, 3.00), and 1.00 (0.00, 2.00), respectively.

OBJECTIVE To investigate the current situation of pharmaceutical management in compact medical consortium of Guangdong province， and to provide decision-making basis for promoting the high-quality construction and sustainable development of the provincial medical consortium. METHODS A self-designed questionnaire was used to select 50 compact medical consortiums in Guangdong province. The survey was answered by the heads of the pharmacy department of the general hospitals. The survey covered the basic scale of the consortium， the appointment of chief pharmacists， the implementation of pharmaceutical management and pharmaceutical care homogenization within the consortium， the difficulties in promoting the homogenization， and the expected provincial support. Descriptive statistical analysis was performed on the survey results. RESULTS A total of 50 questionnaires were collected， and the effective recovery rate was 100%. There were 16 chief pharmacists （32.00%） in charge of the pharmacy department of the general hospital in the medical consortium. Thirty-seven medical consortiums （74.00%） had established a drug supply support system within the consortium， 35 medical consortiums （70.00%） had carried out pharmaceutical management and coordination work within the medical consortium， 23 medical consortiums （46.00%） had established a clinical medication guidance system， 25 medical consortiums chenwenying2016@163.com （50.00%） had established a bidirectional communication mechanism， and only 8 medical consortiums （16.00%） had developed new models of pharmaceutical care. At present， the difficulties in promoting the homogenization of pharmaceutical management and pharmaceutical care within the medical consortium were mainly found in three aspects： the wide gap in management level of each member unit， the lack and uneven level of pharmaceutical personnel， and insufficient policy support and implementation. Most medical consortiums hoped that relevant departments could promote the homogenization of pharmaceutical work by holding special training courses or special supervision. CONCLUSIONS At present， the compact medical consortium in Guangdong province has achieved initial results in the implementation of the chief pharmacist system， the homogenization of pharmaceutical management and pharmaceutical care. However， it is still necessary to improve the coverage of chief pharmacist appointments in the medical consortium， implement the homogenization of pharmaceutical management， and accelerate the homogenization process of pharmaceutical care.

Objective To investigate the effect of applying specialist nursing assessment indicator system on improving nurse′s health assessment ability in orthopedic department. Methods A specialist nursing assessment indicator system was developed by applying evaluation indicators of nursing care quality. That assessment indicator system consisted of 9 sub-indicators. They were assessments on local blood circulation, sensation and motion, muscle strength, pain, risk of developing pressure ulcer, risk of falling down and assessment on anal sphincter function, etc. In addition, standard assessment process was developed and applied to train 54 nurses in orthopedic department, in order to standardize and improve their ability on specialist nursing assessment. Furthermore, the assessment process was transferred into specific nursing interventions to improve nurse′s health assessment ability, too. The accurate rate on those 9 indicated assessments were evaluated and analyzed regularly, pre and post the indicator system application. In the present study, each of the 54 nurses was required to assess five patients basing on the items in the assessment indicator system. The total assessment times were 270. Results After applying the indicator system, the accurate rates of assessments on local blood circulation, sensation and motion, muscle strength, pain, risk of developing pressure ulcer, anal sphincter function and assessment on developing deep venous thrombosis were 98.89% (267/270), 99.63% (269/270), 99.26% (268/270), 97.41% (263/270), 98.15% (265/270), 91.85% (248/270), 98.15% (265/270), which were higher than 95.19%(257/270), 92.96%(251/270), 96.30%(260/270), 90.37%(244/270), 92.22%(249/270), 85.56%(231/270), 92.22%(249/270) of the time when the system was not used, and the difference was significant (χ2=5.34-16.82, P < 0.05). However, the accurate rates on assessing risk of falling down and assessing ADL were not significant different, comparing to the results before applying the indicator system (χ2=0.34, 0.41, P>0.05). Conclusions Applying the specialist nursing assessment indicator system was able to standardize nursing assessment behavior and improve nurse′s assessment ability. In addition, it was beneficial to improve the quality of specialist nursing care in orthopedic department.

BACKGROUND:DCLK1 is a transmembrane microtubule-associated kinase in neurons after mitotic division, which may be the intestinal cancer stem cel marker. OBJECTIVE:To observe the expression and pathological significance of DCLK1 and Ki67 in colorectal cancer. METHODS: Expression of Ki67 and DCLK1 in 150 cases of colorectal cancer tissues was detected by immunohistochemical method in contrast to normal colorectal mucosa, para-carcinoma tissue, and adenoma tissue. RESULTS AND CONCLUSION:The expression rates of DCLK1 and Ki67 were 36.7% and 34.7% in cancer tissues, respectively, both of which were significantly higher than those in normal colorectal mucosa and adenoma. The expression of DCLK1 was associated with the location, depth of invasion, lymph node metastasis (P < 0.05), while the expression of Ki67 was just associated with the depth of invasion (P < 0.05). There was a negative correlation between the expression of DCLK1 and Ki67 (r=-0.460,P=0.000). The count of DCLK1+/Ki67-cels was about 2.01% in colorectal cancer tissues, and these cels mainly distributed at the bottom of intestinal mucosa base and common duct wal. DCLK1+/Ki67- cels were oval, the nuclei were large and deep-stained with prominent nucleolus, and there was rare nuclear fission and less cytoplasm. From the aspects of cel number, location, and cel morphology, DCLK1+/Ki67- cels are in line with the characteristics of cancer stem cels; therefore, DCLK1+/Ki67-can be used as a cancer stem cel marker of colorectal cancer.

Objective To investigate the clinical value of coronary artery Z-scores on echocardiography in diagnosing coronary artery abnormalities. Methods The echocardiography results of 612 patients with Kawasaki disease (KD) at the acute and recovery phase were retrospectively studied. Coronary artery luminal diameters were converted to body-surface-area-adjusted Z-scores. According to coronary Z-scores classiifcation, all the subjects were divided to four groups:415 cases with no dilation (ND), 133 cases with small coronary artery abnormalities (SCAAs), 47 cases with large coronary artery abnormalities (LCAAs), and 17 cases with giant coronary artery abnormalities (GCAAs). Clinical features (gender, age, typical clinical manifestations, fever duration) and laboratory results (CRP, ESR, WBC, PLT) were compared among all the four groups. Coronary artery diameters and the Z-scores were compared between acute and convalescence phase. Results Along with the increase of coronary Z-score, fever duration was prolonged [ND group:(7.75±3.12) d, SCAAs group (8.50±4.12) d, LCAAs group: (8.57±3.58) d, GCAAs group: (11.88±4.33) d, F=22.375, P<0.05]. With coronary Z-score increasing, PLT also increased (F=22.029, P=0.000), and the highest PLT was observed in GCAAs group. There were no significant differences in the CRP, ESR and WBC among all the four groups (F=0.236, 1.116, 0.121, all P>0.05). No significant different coronary diameters were found in ND cases between recovery and acute phase [(2.24±0.34) mm vs (2.33±0.36) mm, t=1.926, P > 0.05]. But there were significant difference in the coronary Z-scores of ND patients between recovery and acute phase (0.41±0.82 vs 1.17±0.75, t=8.332, P < 0.05). The coronary Z-scores in SCAAs group (1.32±0.89 vs 3.40±0.62, t=11.073, P < 0.05), LCAAs group (3.12±2.27 vs 6.20±1.28, t=4.579, P<0.05) and GCAAs group (11.88±6.77 vs 20.4±9.70, t=3.480, P<0.05) at recovery phase were smaller than values at acute phase. Conclusions The KD coronary Z-scores are the body-surface-area-adjusted standard value, and not subject to the influence of children growth and development. Therefore, it may accurately evaluate the severity of coronary artery abnormalities and its recovery process. Accurate quantitative of the coronary artery luminal dimensions is important in KD clinical management and prognosis prediction.
