ObjectiveTo summarize the research progress of ultrasmall superparamagnetic iron oxide (USPIO) enhanced magnetic resonance imaging (MRI) in normal-sized lymph node metastasis of colorectal cancer.MethodThe relevant literatures published recently at domestic and abroad about USPIO enhanced MRI in normal-sized lymph node metastasis of colorectal cancer were collected and reviewed.ResultsUSPIO, a kind of lymph node targeted magnetic resonance contrast agent, could be used to evaluate lymph node metastasis of malignant tumors. USPIO enhanced MRI could detect normal-sized lymph node metastasis in colorectal cancer effectively compared with normal MRI. It provided a higher diagnostic performance than normal enhanced MRI. In addition, USPIO enhanced MRI could also distinguish inflammatory and metastatic lymph nodes better that were difficult to be distinguished by normal enhanced MRI.ConclusionUSPIO enhanced MRI shows a certain potential for clinical application in detecting normal-sized lymph node metastasis of colorectal cancer, but it has not been widely used in China.
Objective To analyze risk factors of acute kidney injury （AKI） after cardiac surgery in adults and develop a clinical score system to predict postoperative AKI. Methods Clinical data of 3 500 consecutive patients undergoing cardiac surgery from June 2010 to April 2011 in Beijing Anzhen Hospital of Capital Medical University were retrospectively analyzed. According to whether they had postoperative AKI，all these patients were divided into AKI group and non-AKI group. AKI group was consisted of 1 407 patients （40.2%） with a mean age of 58±12 years，including 1 004 male patients （71.4%）. The non-AKI group was consisted of 2 093 patients （59.8%） with a mean age of 55±13 years，including 1 259 male patients （60.2%）. Predictive score system of postoperative AKI was established by univariate analysis between the AKI and non-AKI group and multivariate logistic regression and then verified. Results The predictive score system was as followed：male gender （2 points），every 5 years older than 60 years （1 point），diabetes mellitus （2 points），preoperative use of angiotensin converting enzyme inhibitor or angiotensin AT1 receptor blocker （1 point），every 10 ml / （min·1.73 m2） of preoperative estimated glomerular filtration rate （eGFR） under 90 ml / （min·1.73m2） （1 point），preoperative NYHA class Ⅳ （3 points），cardiopulmonary bypass time＞120 minutes （2 points），intraoperative hypotension duration＞60 minutes （2 points），postoperative hypotension duration＞60 minutes （3 points），postoperative peak dosage of intravenous furosemide＞100 mg/day （3 points），postoperative peak dosage of intravenous furosemide 60-100 mg/day （2 points），and postoperative mechanical ventilation time＞24 hours （2 points）. The predictive score system presented a good discrimination ability with the area under the receiver operating characteristic（ROC）curve of 0.738 with 95% CI 0.707 to 0.768，while it also presented a good calibration with Hosmer-Lemeshow statistic （P=0.305）. Conclusion A clinical predictive score system for AKI after cardiac surgery in adults is established，which may help clinicians implement early preventive interventions.
Objectives We aimed to assess the methodological qual ity of RCT on acupuncture for migraine prophylaxis. Methods With the searching terms including acupuncture, migraine, prophylaxis and prevent, etc, the database of the Cochrane Library (Issue 4, 2007), MEDLINE (1966-2007), EMBase (1966-2007), CBM (1978-2007) and CMCC (1994-2007) were searched from their date of start publ ication. Chinese medical journals and relevant academic conference proceedings were hand searched as well. Several items in included trials were assessed, including methodology, diagnostic criteria, inclusion/exclusion criteria, acupuncture/control interventions, outcome measures and follow-up, etc. Result Among the 12 included trials, 9 trials overseas were high-qual ity and 3 in China were low-quality. Frequency or days of migraine attacks and SF-36/SF-12 were often evaluated as outcome measures in western countries, while headache index was used in China. Among the 12 trials, 9 reported the follow-up outcomes and 8 mentioned adverse events. Conclusion There was no high qual ity trial on acupuncture for migraine prophylaxis in China. The outcome measures in trials published in China by now can not evaluate the outcomes of acupuncture for migraine prophylaxis accurately. To study designs, advantages of trials oversea can be used for reference. To Chinese cl inical physicians, prophylactic therapy and abortive therapy of migraine should be distinguished in order to design high-qual ity study on acupuncture for migraine prophylaxis.

Objective To observe the effectiveness of prevention and management of venous thromboembolism (VTE) in the day surgery wards, analyze the influencing factors of VTE occurrence in postoperative patients, in order to reduce the occurrence of VTE adverse events, improve the utilization of medical resources, and enhance the quality of day care. Methods The patient data of the Daytime Diagnosis and Treatment Center of Deyang People’s Hospital between January 2020 and December 2023 were retrospectively selected. According to the implementation time of VTE prevention and control in the day surgery wards, patients between 2022 and 2023 were selected as the observation group, and patients between 2020 and 2021 were selected as the control group. The incidence and the influencing factors of postoperative of VTE were compared between the two groups. Results A total of 2 300 patients were included, with 1 150 cases in each group. The comparison of in-hospital [12 cases (1.0%) vs. 3 cases (0.3%)] and post discharge [7 cases (0.6%) vs. 1 case (0.1%)] VTE incidence rates between the control group and the observation group showed statistically significant differences (P＜0.05). Among the 9 specialties in the Daytime Diagnosis and Treatment Center, the incidence of VTE in thoracic surgery (1.58%), vascular surgery (1.51%), and hepatobiliary surgery (1.29%) ranked among the top 3. The results of multiple logistic regression analysis showed that fourth grade surgery, lower limb surgery, and large intraoperative bleeding (>100 mL) were the influencing factors for postoperative VTE (P<0.05). Conclusions There are many reasons for VTE occurrence, and it is necessary to prevent and treat VTE in the day surgery ward. More attention should be paid to the patient’s surgical grading, intraoperative bleeding volume, and surgical site.
Objective To compare the clinical therapeutic effects of combination therapy of Sanqitongshu capsule and prednisolone with prednisolone alone in the treatment of acute peripheral facial neuritis. Methods A total of 61 patients with facial paralysis were divided into the treatment group and the control group in the outpatient order. The control group used 20 mg oral prednisolone and accepted the non-specific anti-inflammatory treatment every other day. Medication would stop in a week. Oral administration of vitamin B1 and vitamin B12 was also performed for nerve metabolism improvement for 30 days. The therapy of the treatment group was based on the same treatment of the control group with Sanqitongshu capsule for 30 days. Results After 4 weeks, in the treatment group, 20 patients recovered, 5 markedly effective, and 2 effective, and the total effective rate was 90%. In the Control group, 10 patients recovered, 3 markedly effective, and 2 effective, and the total effective rate was 50.0%. There were significant differences between the two groups (Plt;0.05). Conclusion The clinical effectiveness of Sanqitongshu capsule plus prednisolone is better than that of prednisolone alone in the treatment of acute peripheral facial neuritis.
Objective To explore key genes and mechanisms of depression aggravating Crohn disease. Methods In March 2023, the Public Health Genomics and Precision Health Knowledge Base and Gene Expression Omnibus database were used to identify the overlapping differentially expressed genes between Crohn disease and depression and the key genes were screened by Metascape, STRING, Cytoscape, and protein interaction network analysis. The Gene Expression Omnibus database was used to analyze the correlations between key genes and clinical pathologies such as Crohn Disease Endoscopic Index of Severity and intestinal microvilli length. Results There were 137 overlapping differentially expressed genes between Crohn disease and depression, and 25 key genes were further screened out. Among them, CREB1, FKBP5, MAPT, NTSR1, OXTR, PROK2, POMC, HTR2B, and PPARGC1A genes were significantly correlated with multiple clinical parameters. The functions of PROK2 and PROK2-related genes were mainly enriched in neutrophil and granulocyte migration, neutrophil and granulocyte chemotaxis, etc. Conclusions There are 25 key genes, especially CREB1, FKBP5, MAPT, NTSR1, OXTR, PROK2, POMC, HTR2B, and PPARGC1A, that possibly contribute to the establishment and deterioration of Crohn disease caused by depressive disorder. Among these genes, PROK2 showes the possibility of regulating immune cell (neutrophils and CD8+ T cells) infiltration.

ResultsPST technology could prevent anastomotic leakage after rectal cancer surgery from many angles, reduce infection and inflammation, promote postoperative rehabilitation and improve the quality of life of patients, and it is simple and easy to do. The great advantages of PST technology are gradually verified and recognized in clinic. ConclusionPST is a safe and feasible method to prevent anastomotic leakage and relieve the symptoms of anastomotic leakage.
ObjectiveTo explore the effectiveness of traditional Chinese medicine (TCM) acupuncture analgesia after laparoscopic total extraperitoneal inguinal hernia repair (TEP), aiming to reduce the use of analgesics post-surgery. MethodsPatients who underwent unilateral TEP in the Department of Hernia and Abdominal Wall Surgery at our hospital from May 2022 to May 2023 were selected as research subjects. Those who met the inclusion and exclusion criterias were randomly assigned to three groups: TCM acupuncture analgesia group, traditional Chinese medicine acupuncture analgesia plus western medicine analgesia group (referred to as Chinese and western medicine analgesia group), and western medicine analgesia group. The basic information, postoperative numerical rating scale (NRS) pain scores, postoperative recovery indicators, and complication rates of the three groups were analyzed and compared.ResultsThere was no statistically significant differences in the basic data of patients across the three groups (P>0.05). There were significant differences in NRS score, recovery time of intestinal function, first urination time after operation and first ambulation time after operation at each time point after analgesia (6 h, the next morning, 48 h, 72 h and 96 h after operation) among the three groups (P<0.05). The NRS scores in both the TCM acupuncture analgesia group and the Chinese and western medicine analgesia group were lower than those in the western medicine analgesia group (P<0.05), Additionally, postoperative recovery outcomes were better in the TCM acupuncture analgesia group and the Chinese and western medicine analgesia group compared with the western medicine group (P<0.05). There was no significant difference of the above results compared between the TCM acupuncture analgesia group and the Chinese and western medicine analgesia group (P>0.05). There was no significant difference in postoperative complications among the three groups (P>0.05). ConclusionTCM acupuncture analgesia following TEP surgery is effective and leads to improved postoperative recovery compared with the use of oral analgesics alone, without an increase in adverse reactions.
