Based on the theory of "cold qi generates turbidity" described in the Inner Canon of Yellow Emperor （《黄帝内经》）， together with the physiological characteristics of children， who are considered to have an inherent insufficiency of the lung， spleen， and kidney， and the clinical features of recurrent refractory nephrotic syndrome （RNS）， this article proposes that the pathogenesis of RNS in children is characterized by yang deficiency with internal cold， turbidity arising from cold， latent turbidity transforming into toxin， activation by newly contracted pathogens， and turbid toxins damaging the collaterals. The core pathogenesis is identified as yang deficiency， turbidity coagulation， and collateral damage. Accordingly， the general treatment principle is warming yang and eliminating turbidity， with coordination of three methods including warming yang to strengthen the body's foundation， promoting yang to relieve constraint， and raising yang while replenishing qi. Zhenwu Decoction （真武汤） is employed as the basic prescription with modification according to syndrome differentiation， to achieve an effect eliminating turbidity and arresting leakage， restoring kidney function by unblocking the collaterals， and consolidating recovery to prevent relapse.

Objective:To observe the effect of reconstruction of Achilles insertion with Suture bridge technology after extirpation of avulsed bones block in the treatment of Beavis type Ⅲ avulsion fracture of the calcaneal tuberosity.Methods:The retrospective analysis was used. From January 2013 to January 2023, 78 patients with Beavis type Ⅲ avulsion fracture of the calcaneal tuberosity, treated in the Department 1 of Foot and Ankle and Department 2 of Foot and Ankle of the second Hospital of Tangshan were selected as research objects. According to different operation performed, 41 patients with the reconstruction of Achilles insertion with Suture bridge technology after extirpation of avulsed bones block were divided into the observation group and 37 patients with the open reduction internal fixation (ORIF) were divided into the control group. The delayed wound healing rate and the Haglund malformation rate, Maryland foot score, the American Orthopedic Foot and ankle Society (AOFAS) ankle-hindfoot score, the pain Visual Analogue Scale/Score (VAS) score, the Victorian Institute of Sports Assessment-Achilles (VISA-A) score, Arner-Lindholm scale of One-year postoperative were compared between these two groups. The measurement data with normal or approximate normal distribution were analyzed using t test, count data using chi-square test for comparison of between groups.Results:One year after surgery, the incidence of Haglund malformation in the observation group was 4.88% (2/41), which was lower than the control group's 29.73% (11/37). The difference between the two groups was statistically significant ( χ2=8.65,P=0.003). The excellent and good rate of Maryland foot function assessment in the observation group was 85.37% (35/41) higher than that in the control group (56.76% (21/37), and the difference between the two groups was statistically significant ( χ2=7.86, P=0.005). The AOFAS ankle hind foot score of the observation group ((90.44±6.66) points) was higher than that of the control group ((82.84±7.43) points), and the difference between the two groups was statistically significant ( t=4.77, P<0.001). The pain score of the observation group ((1.51±1.05) points) was lower than that of the control group ((2.95±1.13) points), and the difference between the two groups was statistically significant ( t=-5.81, P<0.001). The Achilles tendon score of the observation group ((81.05±5.87) points) was higher than that of the control group ((71.62±8.60) points), and the difference between the two groups was statistically significant ( t=5.70, P<0.001). The excellent and good rate of Arner Lindholm treatment efficacy evaluation for Achilles tendon in the observation group was 87.80% (36/41), which was higher than that in the control group (67.57% (25/37)), and the difference between the groups was statistically significant. Conclusion:The treatment of Beavis Ⅲ type calcaneal nodule avulsion fracture by removing the bone fragment can simultaneously remove the hypertrophic osteophyte, hardened bone, and Haglund deformity of the calcaneus, and clean the degenerated Achilles tendon and inflammatory tissue around the insertion point; The use of suture bridge technology to reconstruct the Achilles tendon insertion point has the advantages of high fixed strength, allowing early functional exercise, avoiding secondary removal of internal fixation, and achieving satisfactory therapeutic effects, which is worthy of clinical promotion.

OBJECTIVE: Exposure to polycyclic aromatic hydrocarbons (PAHs) or metal(loid)s individually has been associated with neural tube defects (NTDs). However, the impacts of PAH and metal(loid) co-exposure and potential interaction effects on NTD risk remain unclear. We conducted a case-control study in China among population with a high prevalence of NTDs to investigate the combined effects of PAH and metal(loid) exposures on the risk of NTD. METHODS: Cases included 80 women who gave birth to offspring with NTDs, whereas controls were 50 women who delivered infants with no congenital malformations. We analyzed the levels of placental PAHs using gas chromatography and mass spectrometry, PAH-DNA adducts with ³²P-post-labeling method, and metal(loid)s with an inductively coupled plasma mass spectrometer. Unconditional logistic regression was employed to estimate the associations between individual exposures and NTDs. Least absolute shrinkage and selection operator (LASSO) penalized regression models were used to select a subset of exposures, while additive interaction models were used to identify interaction effects. RESULTS: In the single-exposure models, we found that eight PAHs, PAH-DNA adducts, and 28 metal(loid)s were associated with NTDs. Pyrene, selenium, molybdenum, cadmium, uranium, and rubidium were selected through LASSO regression and were statistically associated with NTDs in the multiple-exposure models. Women with high levels of pyrene and molybdenum or pyrene and selenium exhibited significantly increased risk of having offspring with NTDs, indicating that these combinations may have synergistic effects on the risk of NTDs. CONCLUSION Our findings suggest that individual PAHs and metal(loid)s, as well as their interactions, may be associated with the risk of NTDs, which warrants further investigation.
