Ulcerative colitis (UC) is a chronic and non-specific inflammatory bowel disease (IBD). Huanglian Ganjiang decoction (HGD), derived from ancient book Beiji Qianjin Yao Fang, has demonstrated efficacy in treating UC patients traditionally. Previous research established that the compatibility of cold herb Coptidis Rhizoma + Phellodendri Chinensis Cortex (CP) and hot herb Angelicae Sinensis Radix + Zingiberis Rhizoma (AZ) in HGD synergistically improved colitis mice. This study investigated the compatibility mechanisms through which CP and AZ regulated inflammatory balance in colitis mice. The experimental colitis model was established by administering 3% dextran sulphate sodium (DSS) to mice for 7 days, followed by CP, AZ and CPAZ treatment for an additional 7 days. M1/M2 macrophage polarization levels, glucose metabolites levels and pyruvate dehydrogenase kinase 4 (PDK4) expression were analyzed using flow cytometry, Western blot, immunofluorescence and targeted glucose metabolomics. The findings indicated that CP inhibited M1 macrophage polarization, decreased inflammatory metabolites associated with tricarboxylic acid (TCA) cycle, and suppressed PDK4 expression and pyruvate dehydrogenase (PDH) (Ser-293) phosphorylation level. AZ enhanced M2 macrophage polarization, increased lactate axis metabolite lactate levels, and upregulated PDK4 expression and PDH (Ser-293) phosphorylation level. TCA cycle blocker AG-221 and adeno-associated virus (AAV)-PDK4 partially negated CP's inhibition of M1 macrophage polarization. Lactate axis antagonist oxamate and PDK4 inhibitor dichloroacetate (DCA) partially reduced AZ's activation of M2 macrophage polarization. In conclusion, the compatibility of CP and AZ synergistically alleviated colitis in mice through M1/M2 macrophage polarization balance via PDK4-mediated glucose metabolism reprogramming. Specifically, CP reduced M1 macrophage polarization by restoration of TCA cycle via PDK4 inhibition, while AZ increased M2 macrophage polarization through activation of PDK4/lactate axis.

OBJECTIVE To provide reference for improving the pre-prescription review system and reducing the occurrence of medication error by analyzing the drug-related problems(DRPs)in the pre-prescription review orders of pediatric outpatient clinics using the Pharmaceutical Care Network Europe(PCNE)classification system.METHODS The data of pre-prescription review orders were retrospectively collected from outpatient department of Shanghai Children's Medical Center,Shanghai Jiao Tong University School of Medicine from July 2022 to June 2023;DRPs in the pre-prescription review orders were classified and summarized by using the PCNE classification system(version 9.1),and then analyzed in terms of types and causes of issues,and the acceptance of interventions.RESULTS A total of 66 017 DRPs orders were included,involving 41 165 patients.The proportion of DRPs orders in children aged ≤5 years old was the highest(58.25％),followed by children aged 6-12 years old(33.52％);the department with the highest proportion of DRPs was internal medicine of pediatrics department(71.41％);the department with the highest incidence of DRPs was thoracic surgery department(9.73％);top three drug categories of DRPs orders were systemic anti-infective drugs(25.26％),Chinese patent medicines(24.74％)and respiratory drugs(22.38％).Referring to PCNE classification system,the types of DRPs mainly focused on treatment safety(64.86％);the reasons of DRPs orders mainly focused on dose selection(82.09％),of which 41.26％were due to excessive drug dosage;92.13％of interventions could be accepted and fully executed by doctors.CONCLUSIONS DRPs orders identified by the pre-prescription review system can be effectively analyzed by using PCNE classification system.Pharmacists should focus on medication use in children aged＜5 years old,update and develop personalized prescription review rules timely,and meet the rational needs of clinical medication for children.

Objective To evaluate the effect of modified and traditional subcostal and anterior quadratus lumborum block on postoperative analgesia in patients with laparoscopic nephrectomy.Methods 46 patients underwent laparoscopic nephrectomy.They were randomly divided into two groups:traditional subcostal quadratus lumborum block(group T)and modified subcostal quadratus lumborum block(group M),with 23 cases in each group.Before anesthesia induction,the T group was subjected to the traditional subcostal and anterior quadratus lumborum block under ultrasound guidance,and the M group was subjected to the modified subcostal quadratus lumborum block under ultrasound guidance.All were given 0.5％ropivacaine 20 ml.Patients controlled intravenous analgesia(PCIA)was performed in both groups.The dermatomal levels of 5min,10 min and 15min after block was recorded.VAS pain scores at rest and cough were recorded at 6,24 and 48 h after the block.The dosage of Sufentanil,the number of analgesic pump compressions and the flurbiprofen rescue were recorded 24 h after surgery.Results The number of block plane segments in group M at 5,10 and 15 minutes after block were 6(4,8),8(6,9)and 8(6,9),respectively,which were significantly more than the T group[4(2,6),6(2,9),6(2,9)](P＜0.05).The VAS pain scores of patients in group M were(1.6±0.5)points at rest and(3.7±0.6)points at cough 6 hours after block,24 hours after the block were(2.3±0.4)points and(3.4±0.4)points,respectively,48 hours after the block were(2.5±0.8)min and(3.2±0.7)min,respectively.The VAS pain scores of and at rest and cough 6 hours after block in T group were(2.5±0.7)points and(5.6±0.8)points,respectively,24 hours after the block were(3.1±0.5)points and(4.5±0.7)points,respectively,48 hours after the block were(3.3±0.6)min and(4.2±0.6)min,respectively.Group M was lower than group T(P＜0.05).In group M,the dosage of sufentanil,the times of analgesic pump and the rate of analgesic relief 24 hours after operation were(23.1±4.3)μg,5(4,7)times and 4.3％,respectively,which were significantly lower than those in T group[(34.7±6.8)μg,11(9,12)times,21.7％](P＜0.05).Conclusion Ultrasound-guided modified subcostal and anterior quadratus lumborum block has better analgesic effect than traditional technique in patients undergoing laparoscopic nephrectomy,which can reduce the amount of postoperative analgesic drugs and effectively relieve postoperative pain.

Objective To explore the value of gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid(Gd-EOB-DTPA)enhanced MRI T1 mapping,R2*quantitative parameters,and their combined indicators in assessing liver function in patients with hepatitis B cirrhosis.Methods The data from 52 patients with hepatitis B cirrhosis who underwent Gd-EOB-DTPA enhanced MRI and modified Dixon quantification(mDixon-Quant)scans were analyzed retrospectively.Patients were divided into three groups based on Child-Pugh scores:Child-Pugh A,B,and C.T1 mapping images were obtained pre,mid,and HBP.Quantitative values of T1 relaxation time reduction rates(△T1 mid and △T1 HBP),liver-related T1 relaxation times(T1 pre,T1 mid,and T1 HBP),fat fraction(FF),and R2* were measured and calculated.One-way ANOVA was used to compare the differences in MRI quantitative parameters between different Child-Pugh grading groups.Spearman's rank correlation analysis was performed to assess the correlation between MRI quantitative parameters and Child-Pugh grading.The receiver operating characteristic(ROC)curve was used to evaluate the performance of distinguishing liver function classification by statistically significant MRI parameters.Results Between different Child-Pugh grading groups,the differences in T1 mid,T1 HBP,△T1 mid,△T1 HBP,and R2*were statistically significant(P＜0.05),however T1 pre and FF were not statistically significant(P＞0.05).T1 mid,T1 HBP and R2*were positively correlated with Child-Pugh grading(rs=0.365,0.566,0.597,respectively;P＜0.05),meanwhile △T1 mid and△T1 HBP were negatively correlated with Child-Pugh grading(rs=-0.680,-0.771,respectively;P＜0.05).There were no significant correlations between T1 pre,FF and Child-Pugh grading(P＞0.05).The area under the curve(AUC)of T1 HBP,△T1 mid,△T1 HBP,R2*and their combined indicators for distinguishing Child-Pugh A grade from Child-Pugh B grade were about 0.888,0.784,0.955,0.764,and 0.961,respectively(P＜0.05).The AUC of △T1 mid,△T1 HBP,R2* and their combined indicators for distinguishing Child-Pugh B grade from Child-Pugh C grade were about 0.853,0.860,0.797,and 0.941,respectively(P＜0.05).Conclusion Gd-EOB-DTPA enhanced MRI T1 mapping and R2*quantitative parameters can be used to independently evaluate the status of liver function in hepatitis B cirrhosis,and the combined evaluation of the two kinds of parameters has a higher diagnostic efficiency.

Objective:To explore the role of tripartite motif-containing protein 21(TRIM21)in chronic apical periodontitis(CAP)and its potential mechanism.Methods:Human CAP tissue and normal periodontal tissue were collected.The expression of inflamma-tory factors(IL-1 β,IL-6,TNF-a,TGF-β1),osteoclast related genes(TRAP,RANKL,CTSK),macrophage polarization related genes(CD86,iNOS,CD206,Arg1)and TRIM21 were detected by RT-qPCR.TRIM21 protein was detected by immunohistochemical staining,and the osteoclasts was detected by tartrate resistant acid phosphatase(TRAP)staining.The inflammation cell model was es-tablished by stimulating Raw264.7 cells with lipoteichoic acid(LTA)or lipopolysaccharide(LPS),and the expression of the above factors was detected.The bone marrow-derived macrophages(BMDMs)extracted from wild-type and TRIM21-/-mice stimulated by LPS were used to verify the expression of the above factors by RT-qPCR,the osteoclasts were detected by TRAP staining,and the po-larization of macrophages was detected by immunofluorescence staining.Results:In CAP tissue the expression of inflammatory factors,osteoclast related genes,CD86,iNOS and TRIM21 increased,while CD206 and Arg1 decreased,and osteoclasts were more than that in normal tissue.The stimulation of LTA/LPS promoted the proliferation of Raw264.7 cells,and the expression of these factors in cells was consistent with that in tissues.After LPS stimulation,BMDMs of TRIM21-/-mice had lighter inflammation,lower expression of os-teoclast specific genes,fewer osteoclasts and lower M1 polarization than those of wild type mice.Conclusion:TRIM21 might promote the progress of CAP by promoting M1 polarization of macrophages.

BACKGROUND:There is no consensus on the optimal bone tunnel position in the lateral clavicle,which guides coracoclavicular ligament reconstruction.Postoperative complications such as enlargement of the lateral clavicle bone tunnel,bone osteolysis,clavicle fracture,and failure of internal fixation are likely to occur.Bone mass density plays an important role in the strength and stability of endophytic fixation.Regional differences in the bone mass density of the distal clavicle should not be overlooked in the repair and reconstruction of acromioclavicular dislocation.Currently,there are no quantitative clinical studies in humans regarding the bone mass density of the distal clavicle. OBJECTIVE:To measure the magnitude of bone mass density in different regions of the distal clavicle by quantitative CT to provide a reference for surgeons to repair and reconstruct the coracoclavicular ligament. METHODS:101 patients undergoing quantitative CT checking in Fuyang People's Hospital Affiliated to Anhui Medical University from October to December 2022 were enrolled,from which 1 616 samples of subdivisional bone mass density of the distal clavicle were measured.For each of the quantitative CT samples,firstly,the distal clavicle was divided medially to laterally into the following four regions:conical nodal region(region A),inter-nodal region(region B),oblique crest region(region C)and distal clavicular region(region D).Secondly,each region was divided into the first half and the second half to determine eight subdivisions,then setting semiautomatic region of interest(ROI)in each subdivision:(ROI A1,A2,B1,B2,C1,C2,D1,and D2).Thirdly,each quantitative CT scan was transferred to the quantitative CT pro analysis workstation,and cancellous bone mass density was measured in the distal clavicle ROI.Finally,the clavicular cortex was avoided when measuring. RESULTS AND CONCLUSION:(1)There was no statistically significant difference in bone mineral density on the different sides of the shoulder(P＞0.05).(2)The analysis of bone mineral density in eight sub-areas of the distal clavicle A1,A2,B1,B2,C1,C2,D1,and D2 showed statistically significant differences(P＜0.05).It could be considered that there were differences in bone mineral density in different areas of the distal clavicle.After pairwise comparison,there was no statistically significant difference in bone mineral density between A1 and A2,D1 and D2,A2 and B1(P＞0.05),and there was a statistically significant difference in bone mineral density between the other sub-areas(P＜0.05).(3)The bone mineral density in the region A2 of the anatomical insertion of the conical ligament was significantly higher than that in the inter-nodular area(region B)(P＜0.05).The bone mineral density in the region A1 was higher than that in the region A2,but the difference was not statistically significant(P＞0.05).The bone mineral density in the region C1 of the anatomical insertion of the trapezium ligament was higher than that in regions C2,D1 and D2,and the bone mineral density in the inter-nodular area(region B)was significantly higher than that in regions C and D(P＜0.05).(4)These results have suggested that there are differences in bone mass density in different regions of the distal clavicle;regional differences in bone mass density in the distal clavicle during repair and reconstruction of acromioclavicular dislocation cannot be ignored.Consideration should be given not only to biomechanical factors but also to the placement of implants or bone tunnels in regions of higher bone mass density,which could improve the strength and stability of implant fixation and reduce the risk of complications such as bone tunnel enlargement,osteolysis,fracture and implant failure.

Objective:To investigate the correlation between the SUV index (SUV max of the lesion/SUV mean of the liver) in 18F-FDG PET/CT imaging and the invasiveness of early lung adenocarcinoma presenting as ground-glass nodule (GGN). Methods:From January 2012 to March 2020, 167 GGN patients (49 males, 118 females; age: (61.5±9.0) years) with early lung adenocarcinoma who underwent PET/CT imaging in Changzhou First People′s Hospital were retrospectively enrolled. The image parameters including the GGN number, location, type, edge, shape, abnormal bronchus sign, vacuole sign, pleural depression, vessel convergence sign, GGN diameter ( DGGN), solid component diameter ( Dsolid), consolidation to tumor ratio (CTR, Dsolid/ DGGN), CT values (CT value of ground-glass opacity (CT GGO), CT value of lung parenchyma (CT LP), ΔCT GGO-LP (CT GGO-CT LP)) and SUV index were analyzed. Single and multivariate logistic regressions were used to analyze the correlation between SUV index and infiltration. The generalized additive model was used for curve fitting, and the piece-wise regression model was used to further explain the nonlinearity. Results:In 189 GGNs, invasive adenocarcinoma accounted for 85.2% (161/189). Single logistic regression showed that the GGN number, type, shape, edge, abnormal bronchus sign, pleural depression, vessel convergence sign, DGGN, Dsolid, CTR, CT GGO, ΔCT GGO-LP and SUV index were related factors of infiltration (odds ratio ( OR) values: 0.396-224.083, P<0.001 or P<0.05). After fully adjusting for confounding factors, SUV index was significantly correlated with increased risk of invasion ( OR=2.162 (95% CI: 1.191-3.923), P=0.011). Curve fitting showed that the SUV index was non-linearly related to the risk of infiltration, and the risk of infiltration increased significantly only when the SUV index was greater than 0.43 ( OR=3.509 (95% CI: 1.429-8.620), P=0.006). The correlation between SUV index and infiltration had no interaction between age, vacuoles, pleural depression and CTR subgroups (all P>0.05). Conclusions:SUV index is an independent factor related to the invasiveness of early lung adenocarcinoma. The higher the SUV index, the greater the risk of invasion; but the two are not simply linearly correlated.

【Objective】 To observe the characteristics and correlation analysis of thromboelastogram (TEG) and platelet related indexes in patients with preeclampsia in late pregnancy. 【Methods】 88 patients with preeclampsia in late pregnancy treated in the Obstetrics Department of Shanghai Ninth People′s Hospital (Northern Hospital) from June 2017 to June 2020 were selected as observation group, and 288 normal pregnant women in late pregnancy with normal prenatal examination were selected as the control. The median elbow vein blood of the two groups were sampled. The TEG and coagulation related indexes of the two groups were compared, and the relationship between TEG and coagulation related indexes in patients with preeclampsia were analyzed. 【Results】 The K, MA, TT, INR and PLT value in the observation group, relative to controls, were significantly higher (P<0.01), but Angle, PT, and APTT value were significantly lower (P<0.01). The variance K and MA were negatively correlated with PT and APTT (P<0.05), but positively correlated with TT, INR and Plt (P<0.05). Angle was positively correlated with PT and APTT (P<0.05), but negatively correlated with TT, INR and Plt(P<0.05). 【Conclusion】 Routine TEG detection can effectively evaluate the coagulation state of patients with preeclampsia, who are often accompanied by coagulation dysfunction, help to guide clinical early prevention and intervention, and reduce the risk of perinatal hemorrhage and embolism diseases, which is worthy of popularizing in clinical.
