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 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.

Objective To determine the effect of knee extension constraint training on bilateral knee biomechanics and bilateral symmetry in running after anterior cruciate ligament reconstruction(ACLR).Methods A total of 33 male patients with unilateral ACL injuries were randomly assigned to a BRACE group of 14 wearing a brace with limitation of knee extension,a PLACEBO group of 10 wear-ing a brace without limitation of knee extension,and a CONTROL group of 9,wearing no brace.All groups underwent unilateral hamstring-auto graft ACLR surgery,immediately followed by 12-week rou-tine rehabilitation.Between week 13 and 48,both the BRACE and PLACEBO groups wore braces for one hour on Mondays.Then,running biomechanical tests were performed at the ends of Week 12 and Week 48,and the bilateral knee extension/flexion angle,moment and inter-leg difference(ILD)were calculated.One-dimensional statistical parametric mapping(SPM1d)two-way ANOVA with repeated measures on one factor was used to identify differences in bilateral knee biomechanics and ILD among the three groups before and after the intervention.Results There was no significant interaction effect of group and time on bilateral knee flexion angle,knee extension moment,and ILD in running(P>0.05).Moreover,no significant effect of group was found on the bilateral knee biomechanics and ILD in running(P>0.05).Additionally,significant effects of time were observed on bilateral knee flexion angle and extension moment in running.However,bilateral knee flexion angle decreased during termi-nal stance(ACLR leg:89%～100%,P=0.036;non-ACLR leg:94%～100%,P=0.046),while the bi-lateral knee extension moment increased during mid-stance(ACLR leg:17%～59%,P<0.001;non-ACLR leg:38%～61%,P<0.001)between week 12 and 48.Conclusion In this study,no improvement was found in the abnormal knee biomechanics and symmetry during running in male patients after uni-lateral ACL reconstruction through long-term knee extension constraint training.Moreover,within one year after ACL reconstruction,the knee extension moment of the surgical limb increased gradually over time,with no changes in the knee flexion angle of the surgical limb and bilateral knee symme-try,suggesting that abnormal knee biomechanics and bilateral symmetry should be paid attention to in the post-surgery rehabilitation.

Objective To compare clinical efficacy of different regimens in treatment of pruritus in maintenance hemodialysis(MHD)patients.Methods A total of 50 patients with MHD admitted to the Sixth People's Hospital of Jiujiang City from August 1,2022 to April 30,2024 as subjects and were divided into two groups according to random number table method.Control group(n=25)was treated with sodium thiosulfate.On this basis,gabapentin combination therapy was added in observation group(n=25).Effects of two groups were compared after 8 weeks of treatment.Results Total clinical effective rate of observation group was significantly higher than that of control group(P＜0.05).After 8 weeks of treatment,scores and total scores of all dimensions of quality of life in two groups were higher than before treatment,and observation group was higher than control group(P＜0.05).Conclusion Sodium thiosulfate combined with gabapentin in treatment of MHD patients with pruritus can not only relieve pruritus symptoms,improve sleep quality,but also have good safety.

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.

Objective:To evaluate the effect of ultrasound-guided internal branch block of superior laryngeal nerve on stress response during endotracheal catheter indwelling in patients undergoing uvulopalatopharyngoplasty (UPPP).Methods:A total of 80 patients with severe obstructive sleep apnea syndrome requiring elective UPPP from the Hunan Provincial People′s Hospital from January 2020 to December 2021 were retrospectively selected and divided into nerve block group (group B) and dexmedetomidine group (group D). Patients in group B and D received general anesthesia. Patients in the group B received bilateral internal branch block of superior laryngeal nerve under ultrasound guidance before postoperative recovery. Patients in the group D received dexmedetomidine intravenously before the end of surgery. The cough scores and mean arterial pressure (MAP), heart rate (HR), plasma epinephrine (E) and norepinephrine (NE) levels of patients before anesthesia (T 1), immediately after recovery (T 2), 2 h after recovery (T 3), 6 h (T 4), and 12 h (T 5) during endotracheal catheterization were recorded in both groups. The Visual Analogue Scale (VAS) scores of T 2, T 3, T 4, T 5 and 24 h after surgery (T 6) were also obtained. Results:Compared with group D, the cough scores of the group B patients were significantly lower, and the number of cases requiring remedial analgesia was significantly less (all P<0.01). Compared with T 1, MAP and HR at T 2-T 5 time points in the group B and HR and MAP at T 2-T 5 time points in the group D were significantly increased (all P<0.05). Compared with the group D, MAP and HR were significantly higher than those at each time point of T 2-T 5 in the group B (all P<0.05). Compared with T 1, the serum NE and E levels in the group D at T 2-T 5 time points, and the serum NE and T 2 E levels in the group B at T 2-T 5 time points were increased, and the differences were statistically significant (all P<0.05). Compared with the group D, serum E and serum NE levels at T 2-T 5 and T 2-T 4 in the group B were significantly lower (all P<0.05). Compared with T 2, T 5-T 6 VAS scores in the group B and T 3-T 6 VAS scores in the group D were significantly decreased (all P<0.05). Compared with the group D, the VAS scores at T 2-T 5 time points in the group B were significantly lower (all P<0.05). Conclusions:Compared with intravenous use of dexmedetomidine, ultrasound-guided internal branch block of superior laryngeal nerve can significantly reduce the discomfort and stress response during catheterization after UPPP, increase the comfort level of patients, reduce the incidence of postoperative complications, and promote rapid recovery of patients.

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).

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.

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.
