ObjectiveThe research focuses on developing modeling and evaluation methodologies for an animal model exhibiting spleen deficiency and dampness excess syndrome， with the aim of standardizing such animal models for future reference. MethodsBy conducting a literature search on animal models of spleen deficiency and dampness excess syndrome， relevant publications meeting inclusion and exclusion criteria will be identified based on publication date， data source， types of diseases involved， animal characteristics， modeling methods， modeling duration， macroscopic syndrome assessment indicators， macroscopic quantification indicators， laboratory testing parameters， intervention approaches， positive controls and application context. A database will be established to facilitate the extraction of this information for quantitative analysis， statistical evaluation， and visual representation. ResultsA total of 137 literature articles meeting the standards have been included in the research. The primary animal species used in animal models of spleen deficiency and dampness excess are SD rats. Modeling methods include single-factor， dual-factor composite， and triple-factor composite methods， with various models widely applied in validation of pharmacological effects and mechanistic explorations. Evaluation indices of animal models for spleen deficiency and dampness excess primarily consist of macroscopic syndrome evaluation indicators and macroscopic quantitative indicators. Laboratory testing indicators are mostly related to research areas such as fluid metabolism and gastrointestinal function. The most commonly studied herbal formulas currently include Shenling Baizhu San and Pingwei San， with natural recovery and the use of the western medicine metronidazole as the most frequently used positive controls. ConclusionThe application of animal models for spleen deficiency and dampness excess is gradually increasing， with various modeling methods already simulating the typical characteristics of this syndrome pattern. However， there are still many areas that are worth contemplating and improving. This study aims to provide reference and ideas for the standardization of symptom names in animal models of spleen deficiency and dampness excess， as well as for the improvement of model construction and evaluation systems.

Objective:To compare esketamine versus dexmedetomidine in improving the adverse mood after cesarean section.Methods:One hundred and fourteen pregnant women undergoing elective cesarean section, aged 20-45 yr, with body mass index≤33 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, were divided into 3 groups ( n=38 each) by the random number table method: esketamine group (group S), dexmedetomidine group (group D) and control group (group C). After delivery, esketamine was intravenously injected as a bolus of 0.3 mg/kg, followed by an infusion of 0.3 mg·kg -1·h -1 throughout the surgery in group S, dexmedetomidine was intravenously injected as a bolus of 0.6 μg/kg, followed by an infusion of 0.6 μg·kg -1·h -1 throughout the surgery in group D, while the equal volume of normal saline was given instead, followed by an infusion of 14 ml/h throughout the surgery in group C. Patient-controlled intravenous analgesia was performed after the end of surgery. Esketamine 50 mg, sufentanil 50 μg and ondansetron 8 mg were given in group S, dexmedetomidine 200 μg, sufentanil 50 μg and ondansetron 8 mg were given in group D, while sufentanil 50 μg and ondansetron 8 mg were given in group C. When the visual analog scale score ≥4 within 48 h after operation, flurbiprofen axidate was intravenously injected as a rescue analgesic. Self-rating Anxiety Scale (SAS) scores and Edinburgh Postnatal Depression Scale (EPDS) scores were assessed at 1 day before surgery and 2 and 7 days after surgery. Serum levels of brain-derived neurotrophic factor (BDNF) were measured by enzyme-linked immunosorbent assay at 1 day before surgery and 2 days after surgery. The effective pressing times of patient-controlled analgesia (PCA) and requirement for rescue analgesia after operation were recorded. The occurrence of adverse reactions during operation and within 48 h after operation was also recorded. Results:Compared with group C, SAS scores and EPDS scores were significantly decreased at 2 and 7 days after surgery, serum BDNF concentrations were increased at 2 days after surgery, the effective pressing times of PCA were reduced, the requirement for rescue analgesia was decreased, and the incidence of intraoperative nausea and vomiting was reduced in S and D groups ( P<0.05). Compared with group D, SAS scores and EPDS scores were significantly decreased at 7 days after surgery, the effective pressing times of PCA were reduced ( P<0.05), and no significant change was found in serum BDNF concentrations at 2 days after surgery and requirement for rescue analgesia in group S ( P>0.05). The incidence of dreaminess was significantly higher in group S than in group C and group D ( P<0.05). Conclusions:Esketamine is better than dexmedetomidine in improving the adverse mood after cesarean section.

Objective: We aimed to investigate the differences of transcriptome profile between 2 groups of high-grade serous ovarian cancer (HGSOC) patients with distinct outcomes and identify potential biomarkers for recurrence. Methods: RNA sequencing was performed in 2 groups of HGSOC patients with similar demographic characteristics but exhibiting distinct progression-free survival (PFS). Transcriptome data of poor response (PR; PFS ≤6 months) and good response (GR; PFS ≥12 months) group were compared. We employed xCell to evaluate the abundance of 63 cells in tumor microenvironment. The predictive value of recurrence-related tumor infiltration cells was validated in cohort data from Gene Expression Omnibus (GEO) and The Cancer Genome Atlas (TCGA) dataset. The weighted correlation network analysis was performed to identify the genes related to cell infiltration. Results: PR patients exhibited a distinct tumor infiltration immune cells-related transcriptional profile compared to GR patients, such as lower signatures of leukocyte differentiation, activation and chemotaxis. The fraction of T-helper 2 (Th2) cells infiltration was significantly higher in PR group than in GR group. High infiltration of Th2 was significantly associated with unfavorable prognosis in the GEO cohort (area under the curve=0.84 at 6 months recurrence) and TCGA cohort (p=0.008). Genes enriched to extracellular matrix organization and integrin binding were relevant to Th2 infiltration. Conclusion Patients with HGSOC having shorter PFS exhibited a distinct gene signature that related to tumor-infiltrating immune cells. The level of Th2 infiltration could facilitate patient recurrence risk stratification and may be a promising biomarker for prognosis prediction and immune-related treatment.

Objective To understand the current practice status of central venous access device(CVAD)maintenance among intensive care unit(ICU)nurses in secondary and above medical institutions in Shandong province,and to provide a basis for further implementation of effective measures to reduce the incidence of central catheter-related bloodstream infections.Methods The CVAD maintenance practice questionnaire was compiled based on domestic and international evidence related to CVAD maintenance,and a survey was conducted in October 2022 to investigate the status of ICU nurses' CVAD maintenance practice in secondary and above medical institutions in Shandong Province.Results There were 1 492 nurses participated in the survey and 1 461 valid questionnaires were recovered,with a valid recovery rate of 97.92％.The type of CVAD used by the nurses was mainly central venous catheters[92.3％(1349/1461)],and the item with the best assessment at each operation was patency of the catheter[81.1％(1185/1461)],and the worst was the patient's feeling[40.7％(594/1 461)].When assessing catheter patency,[59.8％(873/1 461)]of nurses drew back blood into the catheter.In the use of infusion connectors,three-way connectors[76.0％(1 110/1 461)]and heparin caps[62.3％(910/1 461)]were most frequently used.When sterilizing needleless connectors,most nurses could follow the correct range of disinfection,but the time of disinfection needed to be extended,and the most used items for disinfection were povidone-iodine cotton balls/swabs[44.3％(647/1 461)].The timing of changing infusion connectors needs to be standardized.Most nurses would choose saline for catheter flushing,and the number of nurses choosing saline versus heparinized saline when locking the catheter was about 50％.Most nurses can use correct size syringes and follow standardized techniques for flushing and locking.When performing CVAD maintenance,84.7％(1 237/1 461)of nurses chose a specialized care package kit.The most used skin antiseptic was povidone-iodine[63.7％(931/1 461)].Most nurses could follow the standardized range of skin disinfection,but awareness of drying needs to be improved.Dressings covering puncture points were most frequently transparent[99.7％(1 457/1 461)]and gauze[94.7％(1 383/1 461)],and the frequency of gauze dressing changes needs to be standardized.Hand hygiene and aseptic awareness of nurses during CVAD maintenance was good,but hand hygiene and the timing of wearing sterile gloves need to be standardized.Conclusions ICU nurses' CVAD maintenance practices were generally in line with the latest evidence-based recommendations,but assessment,use of maintenance-related items,and hand hygiene and aseptic technique need to be further standardized.It is recommended that nursing administrators enhance ICU nursing human resource allocation as much as possible and form a central line associated bloodstream infection(CLABSI)prevention and control management system to gradually reduce the morbidity of CLABSI within the ICU.

Objective To understand the current situation of practice and cognition of ICU nurses on intra-abdominal pressure monitoring in tertiary general hospitals in Shandong Province,and to analyze the factors affecting their cognition,so as to provide references for formulating intra-abdominal pressure monitoring standards and procedures,and carrying out targeted training in the future.Methods A convenience sampling method was used,and a self-designed questionnaire on practice and cognition of intra-abdominal pressure monitoring was used to survey ICU nurses from tertiary general hospitals in 16 prefecture-level cities in Shandong Province from September to November 2022.Results A total of 627 valid questionnaires were collected,involving 31 tertiary general hospitals(24 tertiary A hospitals,77.42%;7 tertiary B hospitals,22.58%).The operation rate of intra-abdominal pressure monitoring was low(73.37%),and the main reasons were that they had not received intra-abdominal pressure monitoring related training(61.08%),with only 111(24.94%)nurses choosing the intersection of the mid-axillary line and the iliac crest as the reference zero point measurement,274(61.57%)nurses not taking an reading at the end of expiration.The intra-abdominal pressure monitoring cognition score was 0～16(7.88±2.79)points,and only 5 questions had a correct answer rate of≥50%.Conclusion The standardization of intra-abdominal pressure monitoring practice by ICU nurses in tertiary general hospitals in Shandong Province needs to be strengthened,and their cognition needs further training.It is suggested to unify and implement the standards and procedures of intra-abdominal pressure monitoring,further accelerate the training of intra-abdominal pressure monitoring technology,and improve the standard execution rate and cognitive level of ICU nurses on intra-abdominal pressure monitoring.

Objective:To explore the effect of combining motor imagery therapy (MIT) with kinesio taping in rehabilitating the upper limb motor function of stroke survivors.Methods:Ninety-two stroke survivors were randomized into a control group ( n=31), an MIT group ( n=31), and a combination group ( n=30). All were given 40 minutes of basic rehabilitation therapy daily, while the MIT group received additional MIT therapy, and the combination group received kinesio taping with the MIT therapy. The taping was applied according to a patient′s condition and changed every other day. The MIT was conducted twice a day. The experiment lasted 8 weeks, six days a week. Before and after the 8 weeks, the upper limb functioning, ability in the activities of daily living and muscle tension of each subject were assessed using the Fugl-Meyer assessment for the upper extremities (FMA-UE), the Hong Kong version of the functional test for a hemiplegic upper extremity (FTHUE-HK), the modified Barthel index (MBI) and the modified Ashworth scale (MAS). Results:The average post-treatment FMA-UE and MBI scores of the combination group were significantly higher than those of the MIT group, and both were significantly higher than the control group′s averages. The average FTHUE-HK grading of the combination group and MIT group after the treatment was significantly higher than in the control group, with that of the combination group significantly superior to the MIT group′s average. After the intervention the average MAS rating of the combination group was significantly lower than that of the control group.Conclusion:MIT combined with Kinesio taping can significantly improve the upper limb motor functioning of stroke survivors, and significantly reduce their abnormal muscle tone compared to traditional treatments.

Objective:The real-world clinical data of patients with newly diagnosed ovarian cancer (including fallopian tube cancer and primary peritoneal cancer) who received first-line maintenance therapy with poly adenosine diphosphate ribose polymerase inhibitor (PARPi) were retrospectively analyzed, and the prognostic factors were preliminarily explored.Methods:(1) The clinicopathological data and follow-up data of ovarian cancer patients treated with PARPi first-line maintenance therapy from August 2018 (PARPi was launched in China) to December 31, 2021 in Sichuan Cancer Hospital were collected (real-world clinical data). (2) According to the different types of PARPi, real-world clinical data were divided into olaparib group and niraparib group, which were respectively compared with the inclusion and exclusion criteria of representative domestic and foreign phase Ⅲ randomized controlled trials (RCT), including olaparib as first-line maintenance therapy for advanced ovarian cancer patients with BRCA1/2 gene mutation (SOLO-1 study), niraparib as first-line maintenance therapy (PRIMA study), and niraparib as first-line maintenance therapy for Chinese advanced ovarian cancer patients (PRIME study). (3) The prognosis of the two groups and the prognostic factors were analyzed.Results:(1) A total of 83 patients were included in this study, with a median age of 51 years (47-57 years), including 75 cases of ovarian cancer, 5 cases of fallopian tube cancer, and 3 cases of primary peritoneal cancer; 5 cases of stage Ⅰ, 9 cases of stage Ⅱ, 55 cases of stage Ⅲ, 12 cases of stage Ⅳ, and 2 cases of unknown stage; neoadjuvant chemotherapy (NACT) was performed in 40 cases and non-NACT in 43 cases; 62 cases had no visible residual lesion after surgery (R0), 9 cases had residual disease lesions <1 cm (R1), 8 cases had residual disease lesions ≥1 cm (R2), and 4 cases with unknown postoperative residual disease. Thirty-two cases had PARPi treatment interruption, 40 cases had PARPi reduction, and 1 case terminated treatment due to acute leukemia. Of the 83 patients, 35 were in the olaparib group and 48 were in the niraparib group. The proportion of patients with high-grade serous carcinoma (100% and 75%, respectively) and the proportion of BRCA mutant patients (91% and 10%, respectively) in the olaparib group were higher than those in the niraparib group (all P<0.01). (2) Compared with the inclusion and exclusion criteria of the SOLO-1 study, the olaparib group had only 60% (21/35) coincidence rate; compared with the inclusion and exclusion criteria of PRIMA and PRIME studies, the coincidence rates of niraparib group were only 31% (15/48) and 69% (33/48). The most common reasons for non-compliance were number of chemotherapy courses, histopathological type, and surgical pathological stage. (3) Of the 83 cases received first-line maintenance therapy with PARPi, the median follow-up was 15.9 months (11.3-22.9 months), the median progression-free survival (PFS) was 29.7 months (95% CI: 25.9-33.6 months), and the median overall survival was 49.8 months (95% CI: 47.4-52.2 months). Univariate analysis showed that unilateral or bilateral ovarian cancer, efficacy after platinum-containing chemotherapy, presence or absence of measurable lesions at the end of chemotherapy, and total number of chemotherapy courses were significantly associated with PFS (all P<0.05). Multivariate analysis showed that unilateral or bilateral ovarian cancer, total number of chemotherapy courses, and efficacy after platinum-containing chemotherapy were independent factors affecting PFS in stage Ⅱ-Ⅳ patients with PARPi first-line maintenance therapy (all P<0.05). Conclusions:Unilateral ovarian cancer, the total number of chemotherapy courses no more than 9, and achieving complete response after platinum-containing chemotherapy before maintenance therapy are independent influencing factors of PFS benefit in patients with PARPi first-line maintenance therapy. Due to the large differences between the patients in real clinical practice and the research subjects of phase Ⅲ RCT, the results of representative retrospective studies still have important clinical reference significance.

At present, there are many investigations on the status of clinical nurses' information literacy, but less information literacy training is carried out.

Objective:To explore the clinical effect of combining kinesio taping with filtered infrared-A irradiation in the treatment of scapulohumeral periarthritis.Methods:Eighty-six patients with scapulohumeral periarthritis were randomly divided into a control group ( n=43) and an observation group ( n=43). Both groups received 20 minutes of irradiation with water-filtered infrared-A per day for 14 days, while the observation group was also given kinesio taping after the irradiation on 6 days of each week for the two weeks. Before and after the 2 weeks of treatment, both groups were evaluated for pain, their active and passive range of motion (AROM and PROM) of the shoulder, as well as the range of motion (ROM) of the shoulder joint, and their Constant-Murley score (CMS). The subjects also evaluated the functioning of their own shoulders using a visual analogue scale (VAS). Results:After the treatment, the average VAS scores of both groups were significantly higher than before the treatment, but the observation group′s average was significantly higher than that of the control group. There was significant improvement in the average AROM and PROM in both groups, but in the observation group the average AROM in anteflexion, rear protraction, abduction and extorsion and the average PROM in anteflexion and abduction were significantly better than the control group′s averages. The average total CMS scores of both groups had also improved significantly, but with significantly greater improvement in the observation group leading to a significant difference between the two groups after the intervention.Conclusions:Supplementing water-filtered infrared-A irradiation with kinesio taping is very effective in relieving pain, as well as improving ROM and life quality for persons with scapulohumeral periarthritis.

Objective:To analyze the effect of CD100 to monocyte cytotoxicity in non-small cell lung cancer (NSCLC) patients.Methods:Thirty-five NSCLC patients and thirteen healthy controls were included from Zhengzhou Central Hospital between March 2018 and September 2018. Peripheral blood mononuclear cells (PBMC) and bronchial alveolar lavage fluid (BALF) (both tumor site and non-tumor site) was collected from NSCLC patients, while PBMC was collected from healthy controls. Monocytes were purified from PBMC and BALF. Membrane-bound CD100 (mCD100) and CD72 expression on monocytes was measured by flow cytometry. Monocytes from NSCLC patients were stimulated with recombinant human CD100, anti-CD72, matrix metalloproteinase 14(MMP14), or anti-CD100, and were co-cultured with NCI-H1882 cells for 48 h. Tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), granzyme A, granzyme B level in the supernatants, CD16 expression on monocytes, and percentage of target cell death was assessed. Student t test or paired t test was used for comparison. Results:There were no significant differences of peripheral CD14 + mCD100 + percentage, CD14 + CD72 + percentage, CD100 mean fluorescence intensity (MFI), CD72 MFI between NSCLC patients and healthy controls ( P>0.05). CD14 + mCD100 + percentage, CD14 + CD72 + percentage, CD100 MFI, CD72 MFI was remarkably elevated in tumor site compared with in non-tumor site in NSCLC patients ( P<0.05). There was no remarkable difference of peripheral monocytes-induced NCI-H1882 cell death between NSCLC group and control group [(13.95±3.16)% vs (13.22±2.40)%, P=0.451]. Lung-resident monocytes-induced NCI-H1882 cell death was reduced in tumor site when compared with non-tumor site [(11.61±2.81)% vs (14.19±3.57)%, P=0.008 7]. TNF-α, IL-1β, granzyme A, granzyme B level was also decreased in the supernatants of monocytes from tumor site compared with non-tumor site in NSCLC patients( P<0.05). However, there was no statistical difference of CD16 level between two groups( P=0.666). Recombinant human CD100 stimulation promoted NCI-H1882 cell death induced by monocytes from tumor site when compared with unstimulated cells ( P<0.000 1). TNF-α, IL-1β, granzyme A, granzyme B level was also increased ( P<0.05). However, Monocytes, which were pretreated with anti-CD72, induced decreased NCI-H1882 cell death and TNF-α, IL-1β, granzyme A, granzyme B secretion in response to recombinant human CD100 stimulation ( P<0.05). Recombinant human MMP14 stimulation decreased CD14 + mCD100 + percentage and increased soluble CD100 (sCD100) level. NCI-H1882 cell death and TNF-α, IL-1β, granzyme A, granzyme B level was elevated when compared with unstimulated cells ( P<0.05). Anti-CD100 administration decreased sCD100 level. NCI-H1882 cell death and TNF-α, IL-1β, granzyme A, granzyme B level was elevated when compared with MMP14 stimulated cells ( P<0.05). Conclusions:CD100 shedding was insufficient in tumor infiltrating monocytes in NSCLC patients, leading to decreased cytotoxicity. MMP14 might elevate cytotoxicity of tumor infiltrating monocytes via promoting CD100 shedding and sCD100 formation.
