OBJECTIVE To construct a predictive tool for surgical site infections(SSIs)in spinal surgery for Chi-nese population to provide evidence support for reducing SSIs.METHODS A systematic review of Chinese and English database literature was conducted for Meta-analysis to obtain pooled risk values for influencing factors,and a risk prediction scoring tool was constructed based on the logistic regression model.Patients who underwent spinal surgery and completed postoperative follow-up in a tertiary hospital in Beijing from Jan.to Dec.2021 were selected to validate the predictive effect of the tool.RESULTS The predictive model for SSIs in Chinese spinal sur-gery patients was Logit(P)=—3.47+0.63(age 60 years)+0.31 ×(patient with cardiovascular disease)+0.69 ×(rheumatoid arthritis)+1.07 ×(diabetes)+1.06 ×(operation duration＞3 h)+1.17 ×(preopera-tive albumin＜35 g/L)+0.71 ×(history of spinal surgery)+0.67 ×(carrying internal implants)+0.73 ×(blood transfusion).The total score of the predictive tool was 92,with a cutoff score of≥24.50 indicating high-risk individuals.The area under the curve was 0.733,with the sensitivity 58.30％and the specificity 79.60％.CONCLUSION The established predictive model for SSIs in Chinese spine surgery demonstrates good predictive performance and can be used as a reference assessment tool in clinical practice.

OBJECTIVE To assess the current status of hospital-acquired infections and their economic burden in or-thopedic patients based on diagnosis-related groups(DRG).METHOD Based on the National Health Insurance dis-ease diagnosis-related groups,32 413 orthopedic patients from a tertiary care hospital in Beijing in 2021 were grouped,hospital-acquired infections were retrospectively analyzed,and the direct and indirect economic burdens of different DRG groups were assess using indictors such as hospitalization time and cost,bed turnover loss,and labor time loss.RESULTS A total of 32 413 patients were included,the incidence of hospital-acquired infection was 0.47％(153/32 413),the site of infection was predominantly the surgical site(57.99％),and hospital-acquired infections in the hematologic system had a greater impact on cost-consumption indices and time-consumption indi-ces.The infection cases were concentrated in 19.58％of the DRGs groups.The IF23 group(lower limb bone sur-gery with complications and comorbidities)had the highest direct economic burden(24 010 yuan/case)due to hos-pital-acquired infections,and the increase in the cost of consumables and medication was the main factor causing the direct economic burden.At both the hospital level and family-society level,the top three DRG groups in terms of indirect economic burden due to hospital-acquired infections were IB15,IB13 and IF23.CONCLUSION Hospital-acquired infections in orthopedic patients have a tendency to be concentrated,quantitatively assessment of their e-conomic burden based on DRGs not only illustrates the importance of hospital-acquired infection prevention and control,but also accurately identifies the disease groups that require focused management,providing an evidence-based basis for precise prevention and control of hospital-acquired infections.

OBJECTIVE To explore the possible mechanism of Qingchang Huashi Formula in the treatment of ulcerative colitis(UC).METHODS Fifty C57BL/6 male mice were randomly divided into a control(Ctrl)group,a model group,a low-dose Qingchang Huashi Formula group,a high-dose Qingchang Huashi Formula group,and a 5-aminosalicylic acid(5-ASA)group based on body weight.The UC model was established in mice by drinking 3%dextran sulfate sodium(DSS)for 6 d.On d7 and d8,DSS was withdrawn and ultrapure water was given daily.Ultrapure water or different drugs were administered orally throughout the experiment:Ctrl and model groups received 0.2 mL of ultrapure water,while the low-dose and high-dose Qingchang Huashi Formula groups re-ceived 6 and 12 g·kg-1,respectively,and the concentration of 5-ASA was 100 mg·kg-1.Body weight and fecal characteristics of the mice were recorded daily,and the experiment ended on d9.Serum was collected from mice for serum metabolomics and inflam-matory factor expression analysis.The colons of the mice were isolated and their lengths were measured,and the distal colon was ob-tained for pathological analysis.The livers and colons of the mice were isolated for subsequent total bile acid analysis.RESULTS Compared with the Ctrl group,the model group mice showed a significant decrease in body weight and colon length(P<0.000 1),a remarkable increase in disease activity index(P<0.000 1).The concentration of inflammatory factors IL-1β and TNF-α was signifi-cantly increased(P<0.000 1).High-dose and low-dose Qingchang Huashi Formula,as well as 5-ASA could significantly alleviate the loss of body weight,increased DAI,colon shortening,and disappearance of colon tissue morphology in mice.Through ELISA tes-ting,it was found the concentration of IL-1β and TNF-α was remarkably decreased after Qingchang Huashi Formula and 5-ASA treat-ment(P<0.01,P<0.000 1).Through LC-MS analysis of serum metabolites and KEGG enrichment analysis,we found that interven-tion with Qingchang Huashi Formula could significantly affect the primary bile acid synthesis,secondary bile acid synthesis and bile se-cretion.Using total bile acid reagent kit,we found that the total bile acid in the liver of colitis mice did not show significant changes when compared with the Ctrl group of mice,and the concentration of total bile acid in the serum was significantly reduced,the concen-tration of TBA in the colon was significantly increased(P<0.05).After intervention with the Qingchang Huashi Formula,the concen-tration of total bile acid in the serum of mice was significantly increased,while the concentration of total bile acid in the colon was re-duced(P<0.05).Compared with mice in Ctrl group,the levels of deoxycholic acid(DCA)and taurine deoxycholic acid(TDCA)in serum of colitis mice were significantly reduced(P<0.05).After intervention with Qingchang Huashi Formula,the levels of DCA,TD-CA and Ursodeoxycholic acid(UDCA)in serum of mice were restored(P<0.01).CONCLUSION Qingchang Huashi Formula can effectively relieve DSS-induced colitis in mice,reducing immune inflammatory response,reregulating the disorder of serum metabolism and enterohepatic circulation.

The principle of "supplementing or draining by the preference and aversions of the the five zang organs" emphasizes that prescriptions should align the five flavors of medicinals with the needs of the five organs， achieving supplementation through harmonizing flavors and drainage through opposing flavors. This paper analyzed the formulas for regulating the spleen found in Wings of the Thousand Gold Pieces Formulary （《千金翼方》） from the perspective of "supplementing or draining by the preference and aversions"， to summarize SUN Simiao's prescription characteristics for treating spleen-related disorders. In terms of the combination rule of medicinal properties and flavors， formulas like Bupi Decoction （补脾汤） for supplementing the spleen use sweet and warm medicinals paired with bitter and drying medicinals； those for draining the spleen use acrid and warm medicinals paired with bitter and cold medicinals； those for warming the spleen employs acrid and hot medicinals with sweet and warm medicinals； those like Jianpi Decoction （建脾汤） for strengthening spleen combines sweet and warm with sour and bitter medicinals； Zhuanpi Pill （转脾丸） pairs acrid and warm medicinals with sweet and warm medicinals； and Roupi Decoction （柔脾汤） uses sweet and warm medicinals with sweet and bitter medicinals. Regarding the medicinal flavors， warm dominates the four qi （the four properties）， while sweet， bitter， and acrid are the main among the five flavors. Clinical practice involves applying comprehensive therapy methods such as the combination of sweet and bitter to harmonize， acrid and sweet to transform yang， pungent to disperse and bitter to descend， balancing cold and warm， and combining supplementation and drainage. The foundational principle is to tonify spleen qi and protect the middle jiao， and treatment is tailored based on the disease condition， location， nature， and the characteristics of the medicinals， with careful selection of suitable dosage forms and administration methods.

Emerging evidence suggests that dysbiosis of the gut microbiota is associated with the pathogenesis of Parkinson's disease (PD), a prevalent neurodegenerative disorder. The microbiota-gut-brain axis plays a crucial role in the development and progression of PD, and numerous studies have demonstrated the potential therapeutic benefits of modulations in the intestinal microbiota. This review provides insights into the characterization of the gut microbiota in patients with PD and highlights associations with clinical symptoms and underlying mechanisms. The discussion underscores the increased influence of the gut microbiota in the pathogenesis of PD. While the relationship is not fully elucidated, existing research demonstrates a strong correlation between changes in the composition of gut microbiota and disease development, and further investigation is warranted to explain the specific underlying mechanisms.

ObjectiveTo understand the distribution of enrofloxacin (ENR) residues in freshwater fish, to evaluate the dietary exposure risk to ENR for consumers through the consumption of different freshwater fish in Shanghai, and to provide a reference for controlling antibiotic residues in freshwater fish. MethodsGrass carp, Wuchang bream, pond loach, and Asian swamp eels were purchased from the markets in Shanghai. After being fed with ENR, the fish were divided into 42 batches according to their species and weight, and thereafter ENR residues in the muscles and skin of the fish were measured. In addition, a total of 44 batches of Wuchang bream, pond loach, Asian swamp eels were purchased from the markets, and the ENR residues in the muscles with or without the fish skin were measured, and the exposure risk was evaluated. ResultsThe average residues of ENR in skin of the freshwater fish after being fed with drugs in the 42 groups were higher than those in muscles (M=659.38 μg·kg^-1, M=460.83 μg·kg^-1; z=-2.212, P=0.027). The over-standard rates of ENR residues in the muscles with or without skin 44 batches of freshwater fish of sold in Shanghai were 36.36% and 29.55%, respectively. The median exposure, P₉₅ exposure, and maximum exposure to ENR through the consumption of the muscles with the skin for adults and children in Shanghai were higher than those through the consumption of muscles without the skin. For children, the margin of safety (MOS) for the max exposure to ENR by consuming the muscles with the skin was more than 1, while the MOS was less than 1 in all other cases for both children and adults. ConclusionThe ENR residues in the skin of freshwater fish are generally higher than those in the muscles. The risk of ENR residues in freshwater fish sold in Shanghai is within a controllable range. However, there might be a certain risk of acute exposure to ENR for children by consuming muscles with the skin of freshwater fish.
