Based on the theory of diseased collaterals and the progression pattern of diabetic kidney disease （DKD）， this paper proposes a staged treatment system based on the "three states of kidney collaterals" including collateral distention， collateral bi （痹） and collateral accumulation. In the collateral distention stage， the primary pathogenesis is heat damaging the kidney collaterals and collateral vessel dilation， corresponding to the early state of DKD characterized by hyperfiltration and microalbuminuria； the clearing method is suggested， and Shenling Jiangtang Formula （参苓降糖方） can be used to promote the remission of proteinuria by ameliorating insulin resistance and regulating intestinal microecology. In the collateral bi stage， the core pathogenesis lies in the binding of phlegm and stasis， and the formation of concretions and conglomerations in the kidney collaterals， corresponding to massive proteinuria and the decline of renal function， for which the unblocking method should be taken， using Jinchan Yishen Tongluo Formula （金蝉益肾通络方） and Qingre Xiaozheng Formula （清热消癥方） to alleviate renal pathological damage by regulating the autophagy-lysosome pathway and repairing mitochondrial energy metabolism. The collateral accumulation stage is characterized by the internal retention of turbid toxins and accumulations of concretions in the kidney collaterals， corresponding to renal fibrosis and end-stage renal disease （ESRD）； the dispersion method is suggested， and Yiqi Tongluo Xiezhuo Formula （益气通络泄浊方） and Shenyan Fangshuai Fluid （肾炎防衰液） can be used to inhibit extracellular matrix accumulation and delay the progressive loss of renal function. Collateral deficiency runs through the entire course of the disease and is closely related to cellular senescence and the imbalance of the ubiquitin-proteasome/autophagy system. The concept of the "three states of kidney collaterals" integrates the evolution of traditional Chinese medicine pathogenesis with modern pathological staging， forming a whole-course intervention system of "staging-syndrome differentiation-target-formula"， thereby providing novel insights for prevention and treatment of DKD using integrated traditional Chinese and western medicine.

Objective: To understand the home reading-writing levels among children and adolescents in Shanghai after school, and to explore its association with screening myopia, so as to provide a scientific basis for the prevention and control of myopia. Methods: From April to December 2024, 641 primary and middle school students were recruited from 2 urban schools and 1 rural school in Shanghai to participate in the survey. An illuminance meter was used to measure the illuminance of home reading-writing activities after school. Screening myopia was determined through visual acuity examination and refractive detection under non ciliary muscle paralysis conditions among children and adolescents. A binary Logistic regression model was used to analyze the association between home reading-writing illuminance and screening myopia. Results: The detection rate of screening myopia among children and adolescents in Shanghai was 59.9%. The median home reading-writing illuminance after school was 340.9(112.2, 753.5) lx, and 45.4% was found of less than 300 lx. The family illuminance in the primary school stage [432.0 (136.9, 837.0) lx] was higher than that in the junior high school stage [113.1(53.7, 375.1) lx], and main urban area group [503.9 (212.6, 969.5) lx] was higher than that in the rural group [141.6 (53.7, 416.9) lx], the differences were statistically significant (Z=-7.56, -9.95,both P<0.05). The results of Logistic regression analysis showed that compared with the family illuminance of 150-500 lx, children and adolescents with family illuminance<150 and >500 lx had increased risks of screening myopia detection[OR(95%CI)=1.56(1.01-2.42), 1.74(1.15-2.62),both P<0.05]. Conclusions The home reading-writing illuminance after school is suboptimal. Both excessively low and high home reading-writing illuminance levels are associated with screen-detected myopia. It is necessary for children and adolescents to improve lighting conditions during evening reading-writing activities, and strengthen health education according to different regions and school stages.

ObjectiveTo explore the mechanism of total saponins of Dioscoreae Nipponicae Rhizoma （TSDN） in treating gouty arthritis （GA） by regulating cyclooxygenase-2 （COX-2）-mediated M1 macrophage reprogramming by in vivo and in vitro experiments. MethodsIn vivo experiment： 24 male SD rats were randomly allocated into blank， model （GA）， TSDN， and celecoxib groups， with 6 rats in each group. After 7 days of administration， pathological changes in the ankle synovial tissue were observed via hematoxylin-eosin （HE） staining. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to quantify the mRNA levels of NOD-like receptor protein 3 （NLRP3） inflammasome， apoptosis-associated speck-like protein （ASC）， Caspase-1， COX-2， interleukin-1β （IL-1β）， and tumor necrosis factor-α （TNF-α） in the synovial tissue. Enzyme-linked immunosorbent assay （ELISA） was employed to measure the serum levels of inducible nitric oxide synthase （iNOS）， IL-1β， CD86， CD80， CD206， and arginase-1 （Arg-1）. In vitro experiment： The GA model was established by lipopolysaccharide （LPS） + MSU induction， and the inhibitor concentration was screened by the methyl thiazolyl tetrazolium （MTT） assay. RAW264.7 cells were allocated into blank， model， TSDN， dexamethasone， COX-2 inhibitor （celecoxib）， and TSDN + COX-2 inhibitor groups. The levels of iNOS， IL-1β， CD86， CD80， CD206， and Arg-1 in the cell supernatant of each group were determined by enzyme-linked immunosorbent assay （ELISA）. The mRNA and protein levels of NLRP3 inflammasome， COX-2， IL-1β， and TNF-α in each group were determined by Real-time PCR and Western blot， respectively. ResultsIn vivo experiment： compared with the model group， TSDN reduced the mRNA levels of NLRP3 inflammasome， COX-2， IL-1β， and TNF-α in the synovial tissue （P<0.05， P<0.01）. ELISA results showed that TSDN lowered the serum levels of iNOS， IL-1β， CD86， and CD80 （P<0.01） while increasing the serum levels of CD206 and Arg-1 （P<0.01）. In vitro experiment： compared with the model group， TSDN and inhibitor down-regulated the mRNA levels of NLRP3 inflammasome， COX-2， IL-1β， and TNF-α and the protein levels of NLRP3 inflammasome， COX-2， cleaved IL-1β， and TNF-α （P<0.01）. Compared with TSDN alone， TSDN + COX-2 inhibitor further reduced the mRNA and protein levels of the markers above （P<0.01）. Compared with the model group， TSDN and COX-2 inhibitor decreased the levels of IL-1β， iNOS， CD80， and CD86 （P<0.01） and increased the levels of CD206 and Arg-1 （P<0.01） in cells. Compared with TSDN alone， TSDN + COX-2 inhibitor reduced IL-1β， iNOS， CD80， and CD86 levels （P<0.05， P<0.01） and elevated CD206 and Arg-1 levels （P<0.01） in cells. ConclusionTSDN can alleviate GA by downregulating COX-2-mediated M1 macrophage reprogramming and suppressing the inflammatory factors.

Objective:To evaluate the effect of liposomal bupivacaine transversus abdominis plane block (TAPB) on the postoperative quality of recovery in patients undergoing laparoscopic colorectal surgery.Methods:In this randomized controlled trial, 100 patients of either sex, aged 18-75 yr, with a body mass index of 18.5-29.9 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, scheduled for elective laparoscopic colorectal surgery, were allocated into 2 groups ( n=50 each) in a 1∶1 ratio using a random number table method: liposomal bupivacaine TAPB group (LB group) and hydrochloric bupivacaine TAPB group (HB group). Before anesthesia induction, ultrasound-guided bilateral TAPB was performed, liposomal bupivacaine (266 mg) 40 ml (20 ml per side) was injected in LB group, and bupivacaine hydrochloride (100 mg) 40 ml (20 ml per side) was injected in HB group. When pain scores at rest ≥4 within 72 h after the end of surgery, patient-controlled intravenous analgesia with morphine injectio 3 mg was used. The Quality of Recovery-15 scale score was recorded at 24, 48 and 72 h postoperatively. The time to first rescue analgesia and total consumption of morphine within 72 h after operation were recorded. The occurrence of adverse reactions, including nausea and vomiting, urinary retention, pruritus, local anesthetic toxicity and hematoma at the puncture site, was recorded within 72 h after surgery. Results:Compared to HB group, Quality of Recovery-15 scale scores were significantly increased at 24, 48 and 72 h postoperatively, the time to first rescue analgesia was prolonged, the consumption of morphine was reduced within 72 h postoperatively, and the incidence of postoperative nausea and vomiting was decreased( P<0.05), and no statistically significant changes in the incidence of urinary retention or pruritus were found within 72 h postoperatively in LB group ( P>0.05). No local anesthetic toxicity or hematoma at the puncture site occurred in either group. Conclusions:Liposomal bupivacaine TAPB can improve the postoperative quality of recovery in the patients undergoing laparoscopic radical resection for colorectal cancer.

Objective:To investigate the relationship between thoracic aortic calcification (TAC) and autonomic nervous system (ANS) function in patients receiving continuous ambulatory peritoneal dialysis (CAPD).Methods:It was a cross-sectional study. The CAPD patients with dialysis duration >6 months between January and December 2022 were retrospectively enrolled. The baseline clinical data, heart rate variability (HRV) data such as standard deviation of all normal to normal intervals (SDNN), root mean square of successive differences between adjacent normal-to-normal intervals (RMSSD), high frequency (HF), very low frequency (VLF), low frequency (LF), LF/HF, acceleration capacity (AC) and deceleration capacity (DC), and skin sympathetic nerve activity (SKNA) were collected. TAC was defined as TAC score (TACS) >100 AU. The patients were divided into TACS >100 AU group and TACS≤100 AU group based on whether the thoracic aorta was calcified. The differences of those data between the two groups were compared. Logistic regression model was used to analyze the related factors of TAC. Spearman correlation analysis method was used to analyze the correlation between peripheral blood neuropeptide Y, ANS parameters, average amplitude SKNA (aSKNA) and TACS.　Cox regression model was used to analyze the risk factors of all-cause mortality in patients with CAPD.Results:The study included 106 CAPD patients with 50 males (47.2%), age of (46.04±11.10) years and dialysis duration of (41.55±30.52) months. TACS>100 AU group exhibited significantly lower heart rate ( t=2.015, P=0.046), DC ( t=2.131, P=0.035), LF/HF ( Z=3.332, P<0.001) and ln(LF/HF) ( t=3.326, P=0.001), and higher AC ( t=-2.392, P=0.019) than TACS≤100 AU group. Multivariate logistic regression analysis results showed that after adjusting for age and eosinophil count, lnVLF ( OR=0.66, 95% CI 0.45-0.98, P=0.038), lnLF ( OR=0.69, 95% CI 0.49-0.97, P=0.032), DC ( OR=0.79, 95% CI 0.64-0.99, P=0.039) and AC ( OR=1.32, 95% CI 1.04-1.68, P=0.021) were independently correlated with the risk of TAC. Spearman correlation analysis showed that neuropeptide Y level in peripheral blood was correlated with aSKNA ( r=0.23, P=0.017), lnSDNN ( r=-0.20, P=0.036) and TACS ( r=0.19, P=0.048). During the follow-up period of (25.8±4.2) months, 5 patients (4.72%) died, including 1 patient in the TACS≤100 AU group and 4 patients in the TACS>100 AU group. Compared with the survival group, the death group had higher TACS ( Z=-2.262, P=0.024) and lower LF/HF ( Z=-2.750, P=0.006). Cox regression analysis results showed that increased ln(LF/HF) was an independent influencing factor for all-cause mortality in CAPD patients ( HR=0.22, 95% CI 0.05-0.83, P=0.026). Conclusions:HRV parameters (lnVLF, lnLF, AC and DC) of CAPD patients are independently associated with TAC. The dysfunction of ANS in CAPD patients (especially the decreased vagus nerve activity) may promote TAC.

OBJECTIVES: To investigate the therapeutic mechanism of Wendan Decoction for phlegm syndrome in rats with metabolic syndrome (MS). METHODS: Forty Wistar rats were randomly divided into normal control group (n=8) and 3 phlegm syndrome model groups (induced by high-fat, high-sugar, and high-salt feeding and a single-dose intraperitoneal STZ injection; n=24) treated with daily gavage of saline, Wendan Decoction (3.6 g/kg), or metformin (0.1 g/kg) for 4 weeks. General conditions and glucose and lipid metabolism parameters of the rats were monitored, and serum LPS, liver histopathology, hepatic expressions of FXR, CYP7A1 and FGFR4 and ileal expressions of FXR and FGF15 were examined. Gut microbiota structure was analyzed using 16S rDNA sequencing, and serum bile acids were quantified with UHPLC-MS/MS. RESULTS: The rat models of phlegm syndrome exhibited severe hepatic steatosis and necrosis, increased body weight, abdominal circumference, Lee's index, FBG, FINS, HOMA-IR, TG, TC, LDL and LPS, and decreased HDL level. The abundance of Bacteroidetes, Megamonas, and Bacteroides in gut microbiota increased while Firmicutes, Lachnospiraceae_NK4A136_group, isohyodeoxycholic acid, and glycohyodeoxycholic acid decreased significantly; hepatic FXR and FGFR4 expressions and ileal FXR and FGF15 expressions decreased while hepatic CYP7A1 expression increased significantly in the rat models. Treatment with Wendan Decoction effectively alleviated hepatic pathology, reduced body weight and abdominal circumference, improved glucose and lipid metabolic profiles and gut microbiota structure, and reversed the changes in hepatic and ileal protein expressions. Correlation analysis revealed that Firmicutes and Lachnospiraceae_NK4A136_group were positively correlated while Bacteroidetes, Megamonas and Bacteroides were negative correlated with the levels of isohyodeoxycholic acid and hyodeoxycholic acid. CONCLUSIONS Wendan Decoction can significantly improve metabolic profiles in rats with phlegm syndrome of MS possibly by regulating the intestinal flora-bile acid axis to modulate the intestinal flora structure and maintain bile acid homeostasis via the FXR signaling pathway.

Objective:To explore the application of low opioid dose afentanil induced laryngeal mask intubation in patients undergoing breast cancer surgery and its effects on postoperative cognition and mood.Methods:A retrospective study was conducted on 80 patients with radical mastectomy admitted to our hospital from Jan. 2020 to Jun. 2024. Clinical data of the patients were statistically analyzed, and they were divided into control group (47 cases with sufentanil as intravenous sedative drug) and observation group (33 cases with afentanil as intravenous sedative drug) according to different anesthesia methods. The scores of MMSE and Hospital Anxiety and Depression Scale (HAD) before anesthesia and 24 and 48h after anesthesia were compared between the two groups, and the observation group was divided into different subgroups with different doses of afentanil, and the changes of MMSE and HAD scores were observed.Results:There was no significant difference in age, cancer type, clinical symptoms and BMI between 2 groups ( t=0.12, 0.25, P=0.902, 0.801, χ 2=0.05, 2.08, 0.30, 1.69, 0.32, 0.05, 0.08, P=0.978, 0.149, 0.586, 0.193, 0.571, 0.820, 0.960) . At 24h and 48h after surgery, the MMSE score of the 2 groups was significantly decreased, but the score at 48h after surgery was higher than that at 24h after surgery. Meanwhile, the score at 24h after surgery of the observation group) and the score at 48h after surgery, was higher than that of the control group, and the difference was statistically significant ( t=4.15, 4.48, P<0.001) . At 24h and 48h after surgery, the HAD score of the two groups was significantly increased, and the HAD score of the control group at 48h after surgery was significantly higher than that of the control group at 24h after surgery, but the observation group was significantly lower than the control group at 48h, with statistical significance ( t=6.22, P<0.001) . At the induction stage of anesthesia, MMSE scores were significantly higher in the 50-75 μg/kg group than in the 25-50μg/kg group, and HAD scores were significantly lower 48 hours after surgery. At the same time, the MMSE score of 0.5-1.0 μg·kg -1·min -1 group was significantly higher than that of 1.0-2.0 μg·kg -1·min -1 group 48h after anesthesia maintenance, and the HAD score was significantly lower than that of 1.0-2.0 μg·kg -1·min -1 group 48h after anesthesia, with statistical significance ( t=8.80, P<0.001) . Conclusion:Afentanil induced laryngeal mask intubation has high application value in breast cancer surgery patients, which can effectively restore patients' cognitive ability and relieve patients' anxiety, and the effect of low-dose intervention is more obvious, which is worthy of clinical promotion and application.
