Objective:To investigate the clinical efficacy of early versus delayed open reduction and internal fixation in the treatment of tibial pilon fracture. Methods:Sixty patients with tibial pilon fractures admitted to Zhejiang Veteran Hospital from May 2018 to May 2021 were included in this study. They were randomly divided into a control group and a study group ( n = 30/group) using the coin-tossing method. Patients in the control group underwent early reduction and internal fixation within 3 days after injury. Patients in the study group underwent delayed reduction and internal fixation during 7-14 days after injury. The time to bone fracture healing and the time to independent weight-bearing walking were recorded. At 3 and 6 months after surgery, the American Orthopedic Foot and Ankle Society score, Visual Analogue Scale score, clinical efficacy, and incidence of complications were compared between the two groups. Results:The time to bone fracture healing and the time to independent weight-bearing walking in the study group were (8.23 ± 0.63) weeks and (11.77 ± 0.82) weeks, respectively, which were significantly shorter than (9.57 ± 0.86) weeks and (13.40 ± 0.93) weeks in the control group ( t = 6.87, 7.21, both P < 0.001). At 3 months after surgery, American Orthopedic Foot and Ankle Society score in the study group was significantly higher than that in the control group, and the Visual Analogue Scale score in the study group was significantly lower than that in the control group ( t = 6.69, 5.16, both P < 0.001). Overall excellent and good rate of clinical efficacy in the study group was significantly higher than that in the control group (86.6% vs. 63.3%, χ2 = 4.35, P = 0.037). At 6 months after surgery, there were no significant differences in American Orthopedic Foot and Ankle Society score and Visual Analogue Scale score between the two groups ( t = 0.96, 1.12, P = 0.339, 0.267). At 6 months after surgery, there was no significant difference in the overall excellent and good rate of clinical efficacy between the study and control groups (96.6% vs. 90.0%, χ2 = 0.26, P = 0.605). The incidence of complications in the study group was significantly lower than that in the control group (3.3% vs. 26.6%, χ2 = 4.70, P = 0.030). Conclusion:Delayed open reduction and internal fixation after reducing injury to the soft tissue of the affected limbs can effectively shorten the rehabilitation cycle of tibial pilon fracture, increase short-term efficacy, and decrease the risk of postoperative complications.

ObjectiveTo study the correlations of the characteristics of kidney Yang deficiency syndrome in patients with chronic kidney disease (CKD) with clinical indicators and to explore the risk factors of kidney Yang deficiency in CKD. MethodThe differentiation of traditional Chinese medicine (TCM) syndrome classified the 225 CKD patients who met the inclusion criteria into two groups: one group of kidney Yang deficiency syndrome (99 patients) and one group of non-kidney Yang deficiency syndrome (126 patients). The symptoms, tongue manifestation, pulse manifestation, and accompanied symptoms of the kidney Yang deficiency syndrome group were recorded. The syndrome characteristics were summarized by factor analysis and clustering analysis. The levels of hemoglobin, red blood cell count, urinary protein, urinary glucose, creatinine, urea nitrogen and glomerular filtration rate were compared between the kidney Yang deficiency syndrome group, the non-kidney Yang deficiency syndrome group and the normal control group by ANOVA and non-parametric test. The binary logistic regression model was employed to analyze the correlations of lifestyle, body mass index (BMI) with syndrome. ResultThe high-frequency symptoms of CKD patients with kidney Yang deficiency syndrome were waist pain, fear of cold, favor of warm, lethargy, fear of cold at waist and knees, etc. The patients mainly presented deep pulse, thready pulse, or weak pulse, and the tongue with white coating, greasy coating, or thin coating. A total of 13 common factors were obtained, which can be classified into 5 categories. The patients with kidney Yang deficiency syndrome mainly had symptoms in limbs (especially lower limbs), chest, bladder, fleshy exterior, and stomach, with the main manifestations of deficiency-cold, Qi deficiency, fluid retention, and blood stasis. The clustering analysis classified the patients into 11 categories, which reflected that kidney Yang deficiency syndrome mainly presented the symptoms of Qi deficiency, blood stasis, and fluid retention, with fleshy exterior, limbs, spleen, stomach, ears, mind, and bladder involved. The results of clustering analysis and factor analysis were consistent, both of which indicated that the patients were weak with deficiency-cold, accompanied by fluid retention and blood stasis. Frequency analysis also showed that common symptoms mainly included Qi deficiency, fluid retention, cold-dampness, and blood stasis. Compared with the non-kidney Yang deficiency group, the kidney Yang deficiency group showed a large proportion of patients in stage 3-5 CKD, elevated urea nitrogen (P<0.05), decreased glomerular filtration rate, hemoglobin, and red blood cell count (P<0.05), and increased qualitative grade of urine protein. In addition, the results of regression analysis showed that female, little or no exercise, and diet preference were the risk factors for kidney Yang deficiency syndrome in CKD (P<0.05). ConclusionThe disease location and manifestations have correspondence in the CKD patients with kidney Yang deficiency syndrome. The TCM symptoms are correlated with clinical indicators. Hemoglobin, red blood cell count, glomerular filtration rate, urea nitrogen, and urine protein can reflect the connotation of kidney Yang deficiency syndrome in CKD to a certain extent. Additionally, related risk factors in life can affect the occurrence of kidney Yang deficiency syndrome in CKD.

ObjectiveTo analyze the characteristics of kidney Yang deficiency syndrome in different stages and time evolution of chronic kidney disease (CKD) to explore the evolution patterns of kidney Yang deficiency syndrome in CKD. MethodThe evidence information of 256 patients with CKD was collected from October 2020 to September 2022 according to relevant standards, and the "Kidney Yang Deficiency Syndrome Evaluation Scale for Chronic Kidney Disease" was developed. With SPSS Statistics 20.0, SPSS Modeler 18.0, Gephi 0.9.2, and R 4.2.1, the syndrome information of CKD patients at various stages and the syndrome changes after one year were statistically analyzed using complex network analysis, association rule analysis, probability transition matrix analysis, and chi-square test, and the kidney Yang deficiency syndrome of patients at various stages was comprehensively evaluated. ResultIn the CKD population, the proportion of females with kidney Yang deficiency syndrome was higher than that of males (P<0.01), and the proportion of people over 65 years old was higher than in people under 65 years old. The proportion of people with kidney Yang deficiency syndrome increased with the progression of kidney disease, and the proportion of Ⅳ-Ⅴ CKD patients with kidney Yang deficiency syndrome was higher than that of Ⅰ-Ⅱ CKD patients (P<0.01). From Ⅰ CKD to Ⅴ CKD, the frequency of dull tongue continued to increase, and the frequency of enlarged tongue and tooth-marked tongue continued to increase after Ⅲ CKD. The frequency of thick coating and greasy coating ranked in the top 3 of frequency distribution in Ⅴ CKD. After Ⅲ CKD, the top 3 tongue characteristics were weak pulse, deep pulse, and thready pulse, all of which were characteristics of kidney Yang deficiency syndrome. Complex network analysis of the tongue and pulse showed that the core tongue and pulse characteristics of patients with end-stage CKD were tooth-marked tongue with white coating and deep and thready pulse. The results of symptom frequency analysis and complex network analysis showed that aversion to cold and preference for warmth, weakness of the knees, and cold extremities were the top 3 symptoms in Ⅰ-Ⅲ CKD patients with kidney Yang deficiency syndrome, and in Ⅳ-Ⅴ CKD, the manifestations of the syndrome of Yang deficiency and water diffusion, such as drowsiness and fatigue, edema, and frequent urination at night became characteristic symptoms. The scores of edema, pale complexion, soreness and weakness of the waist and knees, loose stools, and mental depression symptoms, as well as the total score of kidney Yang deficiency syndrome gradually increased with disease progression, with statistical differences between different stages of CKD (P<0.05, P<0.01). The frequency analysis of disease-related syndrome elements showed that the frequencies of Yang deficiency syndrome, phlegm-dampness syndrome, blood stasis syndrome, and turbidity-toxin syndrome gradually increased with disease progression, and there were statistically significant differences in the distribution between different stages of CKD (P<0.05, P<0.01). The results of complex network analysis showed that Yang deficiency syndrome was the core syndrome element throughout all stages of CKD and was the main syndrome element type of CKD, while phlegm-dampness syndrome, blood stasis syndrome, and turbidity-toxin syndrome were gradually revealed in the middle and late stages of CKD. In the CKD population with kidney-Yang deficiency syndrome, the distribution of phlegm-dampness syndrome, blood stasis syndrome, and turbidity-toxin syndrome as concurrent syndromes in different CKD stages had statistically significant differences (P<0.05, P<0.01). The association rule analysis showed that as the disease progressed, associations between the concurrent syndromes, such as phlegm-dampness syndrome, blood stasis syndrome, turbidity-toxin syndrome, and fluid retention syndrome, and kidney-Yang deficiency syndrome were gradually enhanced. The comparison of the changes in CKD with kidney Yang deficiency syndrome within one year showed that the disease location was centered on the kidney and transmitted between the spleen, stomach, heart, and liver. There is a 23.81% probability of kidney-Yang deficiency syndrome transforming into Qi deficiency syndromes (Qi deficiency in the spleen and kidney, Qi deficiency in the liver, and Qi deficiency in the heart), 23.79% into Yin deficiency syndromes (Yin deficiency in the liver and kidney, Qi and Yin deficiency, and Yin deficiency in the liver and stomach), and 9.52% into dampness syndromes (phlegm-dampness internal obstruction and wind-dampness obstruction). In contrast, 20% of spleen and kidney Qi deficiency syndrome transformed into kidney Yang deficiency syndrome, and 33.33% of Qi deficiency and blood stasis syndrome transformed into kidney Yang deficiency syndrome. ConclusionAs Ⅰ CKD progresses to Ⅴ CKD, the severity of kidney Yang deficiency syndrome gradually increases, and the syndrome characteristics of kidney Yang deficiency become pronounced. Furthermore, the pathogenic factors, such as phlegm-dampness, blood stasis, and turbidity-toxin, gradually increase. With the change of time, kidney Yang deficiency syndrome in CKD tends to evolve into syndromes related to Qi deficiency, Yin deficiency, and dampness. The discovery of these rules provides a theoretical basis and reference guidance for the treatment of CKD based on syndrome differentiation.
