Urinary system tumors are very common nowadays，including prostate cancer，renal cancer，bladder cancer，and urothelial carcinoma.In recent years，the incidence of these tumors has been on the rise.This paper briefly summarizes the emerging technologies explored by West China Hospital in recent years for urinary system tumors，such as gene sequencing analysis，radiomics and big data，liquid chromatography-mass spectrometry，multi-modal intelligent fusion diagnostic technology，surgical decision-making tools built with artificial intelligence and big data，mRNA vaccines，combination of targeted and immune therapies，and irreversible electroporation technology.These technologies provide strong support and point out the ways for the prevention，early diagnosis，and individualized treatment of urinary system tumors.

OBJECTIVE: To reveal the gap between the evidence of systematic reviews (SRs) and clinical concerns by systematically summarizing the evidence on acupuncture and moxibustion for frozen shoulder and investigating the concerns and needs of clinicians in treatment with acupuncture and moxibustion for this disease. METHODS: The articles of SR and Meta-analysis on acupuncture and moxibustion for frozen shoulder were searched from CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase and Cochrane Library, starting from the inception of each database up to December 31st, 2022. Two researchers screened the articles and extracted data independently. Using AMSTAR-2, the methodological quality of the included studies was evaluated. Based on systematic reviews and expert discussion, a questionnaire on clinical concerns of acupuncture and moxibustion for frozen shoulder was developed and distributed to clinicians. The discrepancies between the evidence and clinical concerns were compared from 5 dimensions, including population, interventions, control measures, outcome indicators and review time points. RESULTS: The evidence gaps existed between SRs and clinical concerns. In the existing studies, the needs of personalized treatment were not fully considered in terms of different syndromes/patterns of frozen shoulder and stages of illness, the outcome indicators were not employed properly, the time for outcome measurement was vague, the control groups were set up outside of standardization, and the methodological quality was lower. CONCLUSION It is suggested that future studies should improve the quality of methodology, lay more consideration to different patient groups, optimize outcome indicators and standardize the setting of control groups, so as to better meet the needs of patients and achieve the best match between evidence and clinicians' needs.

Background::Bladder cancer, characterized by a high potential of tumor recurrence, has high lifelong monitoring and treatment costs. To date, tumor cells with intrinsic softness have been identified to function as cancer stem cells in several cancer types. Nonetheless, the existence of soft tumor cells in bladder tumors remains elusive. Thus, our study aimed to develop a microbarrier microfluidic chip to efficiently isolate deformable tumor cells from distinct types of bladder cancer cells.Methods::The stiffness of bladder cancer cells was determined by atomic force microscopy (AFM). The modified microfluidic chip was utilized to separate soft cells, and the 3D Matrigel culture system was to maintain the softness of tumor cells. Expression patterns of integrin β8 (ITGB8), protein kinase B (AKT), and mammalian target of rapamycin (mTOR) were determined by Western blotting. Double immunostaining was conducted to examine the interaction between F-actin and tripartite motif containing 59 (TRIM59). The stem-cell-like characteristics of soft cells were explored by colony formation assay and in vivo studies upon xenografted tumor models. Results::Using our newly designed microfluidic approach, we identified a small fraction of soft tumor cells in bladder cancer cells. More importantly, the existence of soft tumor cells was confirmed in clinical human bladder cancer specimens, in which the number of soft tumor cells was associated with tumor relapse. Furthermore, we demonstrated that the biomechanical stimuli arising from 3D Matrigel activated the F-actin/ITGB8/TRIM59/AKT/mTOR/glycolysis pathways to enhance the softness and tumorigenic capacity of tumor cells. Simultaneously, we detected a remarkable up-regulation in ITGB8, TRIM59, and phospho-AKT in clinical bladder recurrent tumors compared with their non-recurrent counterparts.Conclusions::The ITGB8/TRIM59/AKT/mTOR/glycolysis axis plays a crucial role in modulating tumor softness and stemness. Meanwhile, the soft tumor cells become more sensitive to chemotherapy after stiffening, that offers new insights for hampering tumor progression and recurrence.

Objective:To construct an evaluation framework with detailed indices for demonstration units (wards) of enteral nutrition nursing, in order to improve the competence of nurses in enteral nutrition nursing and inform the specialized development of enteral nutrition demonstration units (wards).Method:On the basis of literature review and expert discussion, a preliminary draft was developed, and the Delphi expert consultation method was used to conduct two rounds of consultation with 15 clinical experts in the field of enteral nutrition nursing from 15 tertiary hospitals.Results:The effective response rates of questionnaires in two rounds of consultations were both 100%. The first round of expert consultation showed an authority coefficient of 0.90 and a coefficient of variation of 0 to 0.167, while the second round showed an authority coefficient of 0.93 and a coefficient of variation of 0 to 0.113. The Kendall harmony coefficients were 0.338 and 0.368, respectively. Finally, the evaluation framework with detailed indices for the demonstration unit (ward) of enteral nutrition nursing was formed, which consisted of 3 primary indicators, 16 secondary indicators, 54 tertiary indicators, and 62 detailed items.Conclusions:The evaluation framework we developed for the demonstration unit of enteral nutrition nursing follows the diagnosis and treatment process of enteral nutrition management for inpatients, including the triad of structure, process, and outcome. The framework is objective and practical, and can inform the daily practice of enteral nutrition nursing demonstration units (wards) and the development of enteral nutrition nursing specialties.

Objective:To understand the nutritional nursing competence in the enteral nutrition demonstration wards at this stage, so as to inform subsequent training plan.Methods:From September to October in 2023, nurses from 287 institutions involved in the enteral nutrition demonstration ward construction project were selected using convenience sampling. Questionnaires on general characteristics and self-assessment scale on nutrition nursing competence were used for online survey. The status quo and influencing factors of nutrition nursing competence in included institutions were analyzed.Results:A total of 5 409 valid questionnaires were collected, with a response rate of 62.63%. The total score of nutrition nursing competence was 74.74±16.11, with the least subtotals in the domain of nutrtion knowledge. Multiple linear regression showed that influencing factors of nutrition nursing competence includes years of working, department, registered dietitian or not, nutrition management specialist or not, completion of the curriculum in enteral nutrition demonstration ward construction project, and training/supervision arranged by their department concerning nutrtion nursing and relevant evaluation criteria ( P<0.05). Conclusions:The nutritional nursing competence of clinical nurses in the wards involved in enteral nutrition demonstration ward construction project still needs to be improved. Seniors should take into consideration the varying nutritional nursing competence among junior nurses and nurses from different departments, and strengthen the training on nutrition knowledge. It should be encouraged for nurses to actively participate in nutritionist training. Actions including enhancing nutrition specialist training, establishing the multidisciplinary collaborative nutrition care team and conducting regular supervision and assessment should be implemented in the future, to improve the nutritional nursing competence among nurses.

Objective:To investigate the prognosis and influencing factors in critically ill surgical patients of different feeding intolerance trajectories.Methods:The retrospective cohort study was conducted. The clinical data of 354 critically ill surgical patients who were admitted to 69 medical centers in the Chinese Critical Care Nutrition Trials Group -NEED database from March 2018 to July 2019 were selected. There were 247 males and 107 females, aged 58(46,68)years. According to the trajectory model of feeding intolerance change, 354 patients were divided into 3 categories as feeding intolerance, decreased feeding intolerance, continuous feeding intolerance, including 164, 49, 141 cases respectively. Observation indicators: (1) general situations of patients of different feeding intolerance trajectories; (2) treatment of patients of different feeding intolerance trajectories; (3) survival of patients of different feeding intolerance trajectories; (4) analysis of pro-gnostic factors in critically ill surgical patients. Measurement data of normal distribution were expressed as Mean± SD, and one-way analysis of variance was used for comparison between groups. Measurement data of skewed distribution were expressed as M( Q1, Q3), and Kruskal-Wallis rank sum test was used for comparison between groups. Count data were expressed as absolute numbers or percentages, and chi-square test was used for comparison between groups. Ordinal data were compared using the Kruskal-Wallis rank sum test. Bonferroni correction was used for pairwise comparison. Group-based trajectory model was constructed according to Traj plug-in in Stata17.0 statistical software, and the optimal trajectory model was evaluated by Bayesian information criterion and average posterior probability parameter. The Kaplan-Meier method was used to draw the survival curve and calculate the survival rate, and Log-Rank test was used for survival analyses. Univariate and multivariate analyses were conducted using the COX proportional hazard regression model. Results:(1) General situations of patients of different feeding intolerance trajectories. Of 354 critically ill surgical patients, 257 cases underwent enteral nutrition and 97 cases underwent enteral plus parenteral nutrition. The acute physiological and chronic health score (APACHEII) was 17(13,21), and the sequential organ failure score (SOFA) was 6(5,8). The modified Critical Illness Nutritional risk score (mNUTRIC) was 4 (2,5), the number of complications was 2(1,3). There were 293, 55 and 6 patients with grade Ⅰ, grade Ⅱ and grade Ⅲ acute gastrointestinal injury (AGI), and there were 224, 17 and 61 patients who were treated with mechanical ventilation, continuous renal replacement therapy and vasoactive drugs, respectively. The incidence of feeding intolerance in 354 patients increased first and then decreased, reaching a peak of 25.42%(90/354) on the third day and 53.67%(190/354) within 7 days. Of 354 critically ill surgical patients, cases with no feeding intolerance, decreased feeding intolerance, continuous feeding intolerance had the APACHE Ⅱ as 16(12,20), 17(14,25), 18(13,22), mNUTRIC as 3(2,5), 4(3,6), 4(3,5), the number of complications as 2(1,2), 2(2,3), 2(2,3). There were 152, 27, 114 cases with grade Ⅰ AGI, 12, 22, 27 cases with grade Ⅱ-Ⅲ AGI, 95, 39, 90 cases with mechanical ventilation. There were significant differences in the above indicators among the three groups ( H=6.14, 13.11, 28.05, χ2=37.96, 7.65, P< 0.05). Further analysis showed that compared with patients with no feeding intolerance, patients with decreased feeding intolerance and continuous feeding intolerance had the higher number of complications and grade of AGI ( Z=60.32, 54.69, χ2=39.72, 9.52, P<0.05), patients with decreased feeding intolerance had the higher mNUTRIC scores and ratio of mechanical ventilation ( Z=53.41, χ2=7.59, P<0.05). (2) Treatment of patients of different feeding intolerance trajectories. Cases with prokinetic drugs use and post-pyloric feeding were 36, 13 of patients with no feeding intolerance, 25 and 10 of patients with decreased feeding intolerance, 46 and 19 of patients with continuous feeding intolerance, respectively, showing significant differences in the above indicators among the three groups ( χ2=15.76, 6.20, P<0.05). Further analysis showed that compared with patients with no feeding intolerance, patients with decreased feeding intolerance had higher ratio of prokinetic drugs use and ratio of post-pyloric feeding ( χ2=15.60, 6.10, P<0.05). (3) Survival of patients of different feeding intolerance trajectories. The 28-day overall survival rates of patients with no feeding intolerance, decreased feeding intolerance, and continued feeding intolerance were 96.96%, 95.92%, and 87.94%, respectively, showing a significant difference ( χ2=10.39, P<0.05). Further analysis showed a significant difference between patents with no feeding intolerance and patients with continuous feeding intolerance ( χ2=9.19, P<0.05). (4) Analysis of prognostic factors in critically ill surgical patients. Multivariate analysis showed that continuous feeding intolerance was an independent risk factor for 28-day death in critically ill surgical patients ( hazard ratio=3.92, 95% confidence interval as 1.43-10.79, P<0.05). Conclusion:For surgical critically ill patients, patients with continuous feeding intolerance have a higher 28-day mortality than patients with no feeding intolerance, and the continuous feeding intolerance is an independent risk factor for 28-day death in critically ill surgical patients.

Objective:To identify the effective concentrations of Ropivacaine in the modified fascial iliac compartment block(FICB)that would not affect the movement of the affected limb but would offer effective pain relief after total knee arthroplasty(TKA)in elderly patients.In addition, adverse reactions within 24 hours of FICB were examined.Methods:This study was a prospective, single-arm sequential trial.Forty-five elderly patients treated with TKA at the First Affiliated Hospital of Soochow University between September 2021 and March 2022 were selected, with an American Society of Anesthesiologists(ASA)score of Ⅰ or Ⅱ.All patients were given ultrasound-guided FICB on the surgical side under general anesthesia and 10 minutes before the operation, and the injection volume was 30 ml.According to preliminary experiments and relevant literature, the initial concentration of Ropivacaine was 0.1%, and the concentration for the next patient was determined using a modified Dixon sequential method.If the quadriceps femoris muscle strength score of the first patient was ≥4, there was no resting pain[visual analogue scale(VAS)score ≤1], and the VAS score during activity was ≤3, the concentration for the next patient would be reduced.Conversely, the concentration would be increased.The Ropivacaine concentration was increased or decreased by 0.01% each time and the trial would be stopped after 12 reentries.The median effective concentration(ED50), 95% effective concentration(ED95)and corresponding 95% confidence interval(CI)of ropivacaine were calculated using the probit model.Meanwhile, adverse reactions within 24 hours of FICB were monitored.Results:Of 43 elderly patients who completed the trial, the intervention was effective in 23 and ineffective in 20.While ensuring that postoperative limb movement in elderly patients was not affected, a single injection of 30 ml ropivacaine through FICB was able to effectively inhibit postoperative pain, and the ED50 and ED95 of ropivacaine were 0.072%(95% CI: 0.065%-0.078%)and 0.093%(95% CI: 0.084%-0.124%), respectively.Within 24 hours of FICB, 2 patients had lower limb weakness and could not get out of bed and walk, and 5 patients had severe pain and needed additional analgesics.No other adverse reactions were found. Conclusions:The effective ED50 and ED95 of Ropivacaine for postoperative pain relief in elderly patients after TKA are 0.072% and 0.093%, respectively.And the incidence of adverse reactions is low.

Objective : To investigate the role of early inhibition of Toll⁃like receptor 4 (TLR4) in regulating hippampal neuroimmune responseto adolescent ratsafter neonatal hypoxic⁃ischemic brain damage(HIBD) . Methods: Postnatal day 7 rats were randomized into controlgroup , hypoxic ischemia (HI) group , and HI + TAK⁃242( the specific inhibitor of TLR4)(TAK⁃242) group. The expression of TLR4 in rat hippocampus was detected by immunohistochemistry at 3 days after HI. Immunofluorescence were used to determine the number of Iba⁃1 + , GFAP + , CD161 + , MPO + and CD3 + cells in the hippocampus at 21 days after HI. Immunohistochemistry was used to detect ICAM⁃1 and C3a expression in the hippocampal CA1 region ; and Western blot was used to detect tumor necrosis factor interleukin IL⁃1β , TNF⁃α and IL⁃10 expression. Results : Compared with control group , significantly raised TLR4 expression was observed in the left hippocampal CA1 , CA3 and DG regions(P < 0. 01 or P < 0. 05) , while the expression in the TAK⁃242 group lowered compared to the HI group (P < 0. 05) . The number of GFAP + cells in the CA1 area of the hippocampus in the TAK⁃242 group of neonatal rats decreased compared to which in the HI group at 21 days after HI(P < 0. 05) , but the number of CD3 + T lymphocytes in the hippocampal CA1 area of new born rats in the HI group increased compared to which in the Control group (P < 0. 05) , but the difference between TAK⁃242 and the Control group was not statistically significant. The number of Iba⁃1 + cells , MPO + cells , CD161 + cells , the expression of ICAM⁃1 and C3a in hippocampal CA1 region , and the expression of TNF⁃α , IL⁃1β and IL⁃10 in hippocampus of rats were not different among groups at 21 days after HIBD. Conclusion Early inhibition of TLR4 may ameliorate adolescent neuroimmune disorders by reducing the increase of hippocampal astrocytesafter neonatal HIBD.

Background::DOK3 (Downstream of kinase 3) is involved primarily with immune cell infiltration. Recent research reported the role of DOK3 in tumor progression, with opposite effects in lung cancer and gliomas; however, its role in prostate cancer (PCa) remains elusive. This study aimed to explore the role of DOK3 in PCa and to determine the mechanisms involved.Methods::To investigate the functions and mechanisms of DOK3 in PCa, we performed bioinformatic and biofunctional analyses. Samples from patients with PCa were collected from West China Hospital, and 46 were selected for the final correlation analysis. A lentivirus-based short hairpin ribonucleic acid (shRNA) carrier was established for silencing DOK3. A series of experiments involving the cell counting kit-8, bromodeoxyuridine, and flow cytometry assays were performed to identify cell proliferation and apoptosis. Changes in biomarkers from the nuclear factor kappa B (NF-κB) signaling pathway were detected to verify the relationship between DOK3 and the NF-κB pathway. A subcutaneous xenograft mouse model was performed to examine phenotypes after knocking down DOK3 in vivo. Rescue experiments with DOK3 knockdown and NF-κB pathway activation were designed to verify regulating effects. Results::DOK3 was up-regulated in PCa cell lines and tissues. In addition, a high level of DOK3 was predictive of higher pathological stages and worse prognoses. Similar results were observed with PCa patient samples. After silencing DOK3 in PCa cell lines 22RV1 and PC3, cell proliferation was significantly inhibited while apoptosis was promoted. Gene set enrichment analysis revealed that DOK3 function was enriched in the NF-κB pathway. Mechanism experiments determined that knockdown of DOK3 suppressed activation of the NF-κB pathway, increased the expressions of B-cell lymphoma-2 like 11 (BIM) and B-cell lymphoma-2 associated X (BAX), and decreased the expression of phosphorylated-P65 and X-linked inhibitor of apoptosis (XIAP). In the rescue experiments, pharmacological activation of NF-κB by tumor necrosis factor-α (TNF-α) partially recovered cell proliferation after the knockdown of DOK3.Conclusion::Our findings suggest that overexpression of DOK3 promotes PCa progression by activating the NF-κB signaling pathway.
