ObjectiveTo determine the optimal combination of the effective monomer components "quercetin-kaempferol-abietic acid-boswellic acid" in Fujin Shengjisan for promoting diabetic ulcer （DU） wound healing through uniform design， thereby achieving the modern application of the ancient formula. MethodsFollowing the principle of "uniform design-pharmacodynamic experiment-mathematical modeling and model verification"， the U₁₄（14⁵） uniform design table was adopted.The four monomer components of Chinese medicine were considered as the independent variables， and the proliferation rate of human umbilical vein endothelial cells （HUVECs） induced by glucose was used as the pharmacodynamic indicator. A mathematical model was constructed using DPS software to correlate the effective monomer components with the pharmacodynamic indicator. The results of uniform design were verified through CCK-8 assay， cell scratch healing， tube formation， Western blot， and Real-time PCR. ResultsAmong the 14 compatibility groups， compared with the high-glucose model group， compound compatibility group 6 showed the strongest proliferation effect and statistical significance （P<0.05）. Four quadratic polynomial regression equations （Y₁-Y₄） were obtained through DPS modeling. Considering the model's fit， stability， and practical application， equations Y₁-Y₃ were selected for the follow-up verification. To ensure experiment reproducibility， group 6 was used for validation. Group 6 and equations Y₁-Y₃ were renamed as compound prescription ① to compound prescription④， respectively， to represent the modern application of the ancient FJSJ Powder through compatibility of monomer components. Verification experiments showed that in the CCK-8， scratch healing， and tube formation assays， the cell viability， wound healing rate， and tube formation number of HUVECs stimulated with 50 mmol·L^-1 glucose were significantly reduced compared with the blank group. Moreover， the expression levels of angiogenesis-related cytokines， vascular endothelial growth factor （VEGF） and fibroblast growth factor 2 （FGF2）， and CD31 secretion were significantly down-regulated. However， after intervention with compound prescriptions ① to ④， compound prescriptions ① and ③ significantly improved the biological functions of HUVECs induced by 50 mmol·L^-1 glucose. Further analysis of the regression coefficients of compound prescriptions ① and ③， and the relative dose ratios of each monomer component， indicated that abietic acid， quercetin， and boswellic acid promoted angiogenesis of HUVECs in the high glucose environment， with a major effect （positive partial correlation coefficients， all > 0.9）. Abietic acid and boswellic acid， as well as kaempferol and boswellic acid， promoted angiogenesis in HUVECs through interaction （positive partial correlation coefficients）. ConclusionCompound prescriptions ① and ③ are the optimal combinations. They can reverse the inhibitory effects of high glucose， stimulate the proliferation， migration， and tube formation abilities of HUVECs in a high glucose environment， and promote the expression of vascular endothelial growth factorA（VEGFA）， FGF2， and CD31， thereby promoting angiogenesis and facilitating DU wound healing. This finding not only confirms the good reproducibility and feasibility of compound prescriptions ① and ③ but also provides new insights and methods for the rational construction of mathematical models to further study the compatibility theory of Chinese medicine.

Objective:To investigate the efficacy, safety and recurrence rate of oral atenolol in the treatment of infantile hemangioma, so as to provide evidence-based medicine basis and reference for clinic.Methods:Search on the following public databases from January 1, 2008 to June 13, 2022: Web of Science, PubMed, Cochrane Library, Embase, U. S. National Library of Medicine Clinical Trials Registry Platform; China National Knowledge Infrastructure(CNKI), Chinese Biomedical Literature Service System(SinoMed), Chinese Science and Technology Journal Database and Wanfang Data. According to inclusion and exclusion criteria, studies on oral atenolol for the treatment of infantile hemangioma were selected. The outcome indicators were efficiency (complete response rate), incidence of adverse effects and recurrence rate. The single-arm meta-analysis was performed using R software version 4.1.2. Egger’s test was employed and funnel plots were drawn to assess publication bias in the literature.Results:A total of 14 studies were included, comprising 5 randomized controlled trials, 5 single-arm studies, 3 non-randomized controlled trials, and 1 case-control study. The oral administration of atenolol for the treatment of infantile hemangiomas resulted in an efficacy rate (complete remission rate) of 62% (95% CI 52%~71%). The incidence rate of adverse reactions related to the digestive system was 18% (95% CI 7%~30%), while that related to β2 receptor blockade was 4% (95% CI 2%~6%), central nervous system-related adverse reactions occurred at a rate of 10% (95% CI 5%~16%), the recurrence rate was 5% (95% CI 2%~9%). Egger’s test indicated that there was no significant publication bias in the efficacy rate, central nervous system-related adverse reaction rate, and gastrointestinal-related adverse reaction rate of oral atenolol treatment for infantile hemangiomas ( P>0.05). The sensitivity analysis for the efficacy rate, adverse reaction rate, and recurrence rate of oral atenolol treatment for infantile hemangiomas suggested that the result were stable and reliable. Conclusion:Oral administration of atenolol for the treatment of infantile hemangiomas demonstrates significant efficacy, fewer adverse reactions, and a low recurrence rate, making it a promising candidate as a reasonable alternative to oral propranolol for treating infantile hemangiomas.

Objective:To summarize the effect of Chinese Children′s Cancer Group (CCCG) Wilms tumor (WT)-2015 protocol.Methods:This was a prospective study. CCCG-WT-2015 protocol was revised on the basis of the CCCG-WT-2009 protocol. Clinical data of 288 children diagnosed with newly diagnosed kidney neoplasms in fourteen pediatric centers between September 2015 to December 2018 were summarized. The age of onset, distribution of pathological subtypes, staging, curative effect and prognostic factors of these children were analyzed. Kaplan-Meier method was used for survival curve and Log-Rank method was used for univariate analysis.Results:Among 288 cases with kidney neoplasms, there were 261 cases of WT, including 254 cases (97.3%) with favorable histology (FH) WT and 7 cases (2.7%) with unfavorable histology WT (UFHWT). The 3 year events free survival (EFS) rate for FHWT and UFHWT were (88.9±2.1)% and (80.0±17.9)%, which were better than that in WT-2009 (81.2% and 71.7%). In the 96 cases of stage Ⅲ/Ⅳ FHWT with indications for radiotherapy, 76 cases received radiation, another 20 cases received M protocol chemotherapy (cyclophosphamide, etoposide, gentamycin, vincristine and adriamycin) instead of radiation. The 3 year EFS rate for these two groups were (84.7±4.3)% and (84.7±8.1)%(χ 2=0.015, P=0.902). There were 22 renal clear cell sarcoma and 5 malignant rhabdoid tumor, 3 year EFS rate of them was (94.4±5.4)% and (20.0±17.9)%. Univariate analysis was performed for age, gender, pathological type, stage, whether rupture occurred during operation, whether complete remission (CR) occurred at the end of treatment and radiotherapy. Pathological types (χ 2=44.329, P<0.01) and failure to achieve CR at the end of the treatment (χ 2=49.459, P<0.01) were independent factor for predicting survival. Conclusion:Compared with CCCG-WT-2009, treatment of renal tumors in CCCG-WT-2015 study yielded good survival outcome, which can be further applied.

Objective:To investigate the application value of third-generation dual-source CT(3-G DSCT) low-dose scan mode combined with iterative reconstruction technology in the screening of COVID-19 and to evaluate the radiation dose.Methods:One hundred and twenty patients suspected of COVID-19 from December 2019 to February 2020 were retrospectively analysed and randomly divided into two groups (test group and conventional group, 60 patients in each). The parameters for test group included 3-G DSCT, Turbo Flash scan mode, CARE kV, with reference 90 kV, pitch 2.0, and ADMIRE algorithm, while those parameters for conventional group included the 128-slice CT, conventional spiral scan mode, 120 kV, pitch 1.2, and FBP algorithm. The CT values of aorta, spinal posterior muscle, and subcutaneous fat, the aortic noise, signal-to-noise ratio (SNR), and contrast noise ratio (CNR) were compared to evaluate the image quality between two groups. Two experienced doctors scored the image quality using a double-blind method, and compared the CT dose index volume (CTDI vol), dose-length product (DLP), and effective dose ( E) of the two groups. Results:The CT value of the aorta and spinal posterior muscle and the aortic SNR in the test group were (45.38±4.77), (53.41±8.44) HU, and 2.82±0.59, and significantly higher than those in the conventional group [(39.68±6.26), (42.66±6.32) HU, 2.58±0.61, t=5.608, 7.897, 2.162, P<0.05]. The aortic noise, CNR and subjective scores between the two groups had no significant difference( P>0.05). The CTDI vol, DLP, and E in the test group were (3.09±1.02) mGy, (107.57±32.81) mGy·cm, (1.51±0.46) mSv, significantly lower than those in the conventional group [(7.00±1.80) mGy, (261.65±73.93) mGy·cm, (3.66±1.03) mSv; t=-14.680, -14.756, -14.756, P<0.05]. Conclusions:In the screening of COVID-19, using low-dose scanning mode of 3-G DSCT combined with iterative reconstruction technology would provide diagnostic quality images and meanwhile effectively reduce the radiation dose and improve the SNR of the image.

Objective:To explore a low dose CT scanning method on novel coronavirus (COVID-19) pneumonia based on infection prevention and control.Methods:A total of 140 patients with confirmed novel coronavirus pneumonia in Xiehe hospital from January 20, 2020 to February 28, 2020 were undertaken CT scan and divided into low dose group and conventional dose group.

OBJECTIVE: The study is to evaluate our results of patients with sinonasal inverted papilloma (SIP) undergoing endoscopic sinus surgery and to investigate the recurrence relative factors of SIP. METHOD: A retrospec- tive analysis was performed of medical records for 54 cases SIP treated with endoscopic resection. Compared to pre operation imaging evaluation and intraoperative observation, efficacy assessments included endoscopy during follow-up after operation and combined with CT examination results. RESULT: The incidence of 54 cases with ethmoid sinus, part of the lateral wall of the nasal cavity was higher. The recurrence rate was higher in the cases invaded front and/or inferior wall of maxillary sinus, frontal recess. There was no case with middle turbinate. Canceration with the same time accounted for 1.85%. CONCLUSION Misdiagnosis as polyps, the lesion sites of tumour, involving the frontal recess, front and inferior wall of maxillary sinus are the risk factors of recurrence. The preoperative accurate judgment of the primary tumor site and surgical resection completly are the most effective means of preventing recurrence. Postoperative endoscopy examination combined with CT examination is an effective means for the evaluation of recurrence.
