RESUMO
Objective:To study the clinical effect of balloon compression closure kyphoplasty in the treatment of fresh single-segment vertebral compression fracture.Methods:A retrospective study was used to analyze the clinical data of 80 patients with osteoporotic vertebral compression fracture (OVCF) admitted to Gansu Provincial Hospital of Traditional Chinese Medicine from June 2019 to June 2021. They were divided into two groups according to the surgical methods: the simple percutaneous kyphoplasty (PKP) group and the percutaneous kyphoplasty compression group, with 40 patients in each group. The PKP group was routinely treated with PKP, and the PKP compression group was treated with balloon compression occlusion technology on the basis of the PKP group. The amount of bone cement injected, the leakage of bone cement, the height of the anterior edge of the injured vertebra, the Cobb angle of kyphosis, the visual analogue score (VAS) and the Oswestry dysfunction index (ODI) were compared between the two groups. The measurement data conforming to the normal distribution were expressed as ( ± s), and the comparison between the two groups was conducted by t-test; The counting data were expressed by n(%) and the comparison between the two groups adopts Chi-square or Fisher exact probability. Results:The amount of bone cement injected and the leakage rate of bone cement in the PKP compression group were significantly higher than those in the simple PKP group ( P<0.05). The height of the anterior edge of the injured vertebra in the two groups was significantly higher than that before the operation on the first day and three months after the operation ( P<0.05). The Cobb angle, VAS score and ODI index of the injured vertebra in the two groups were significantly lower than that before the operation on the first day and three months after the operation ( P<0.05). The height of the anterior edge of the injured vertebra in the PKP compression group was significantly higher than that in the PKP group ( P<0.05). The Cobb angle of kyphosis in the PKP compression group was significantly lower than that in the simple PKP group at 1 day and 3 months after operation ( P<0.05). There was no significant difference in VAS score between PKP compression group and PKP group on 1 day after operation ( P>0.05), and compared with PKP group on 3 months after operation ( P<0.05). There was no significant difference in the ODI index between the PKP compression group and the two groups 1 day and 3 months after PKP ( P>0.05). Conclusion:Balloon compression closure technology can significantly reduce the leakage of bone cement in PKP and increase the amount of bone cement injected, which is beneficial to reduce the pain of vertebral body and improve the function of OVCF patients, and can improve the clinical treatment effect, which is worth promoting.
RESUMO
ObjectiveTo assess the health risk of dietary exposure to nonylphenol in infants aged 0-36 months through infant formula in Shanghai. MethodsA monitoring of nonylphenol pollution in infant formula was conducted in 2022. A total of 90 samples were obtained from maternal and infant stores， supermarkets， and online stores in Shanghai. Based on the daily consumption data of infant formula， a point assessment method was used to assess the dietary exposure to nonylphenol in infant formula. ResultsThe prevalence of nonylphenol in infant formula retailed in Shanghai was 95.6% （86/90）. The amount of nonylphenol varied from non-detected to 22.70 μg·kg-1， with the mean value of 8.47 μg·kg-1 and the P50 value of 7.77 μg·kg-1. The mean daily nonylphenol exposure （estimated by body weight） from infant formula in infants aged 0-6 months， 7-12 months and 13-36 months in Shanghai was 0.091， 0.068 and 0.054 μg·kg-1， respectively； furthermore， the P95 value of daily exposure （by body weight） was 0.228， 0.152 and 0.119 μg·kg-1， respectively. These amounts were much lower than the tolerable daily intake （TDI） of nonylphenol （by body weight 5 μg·kg-1）. ConclusionThe health risk of daliy nonylphenol intake from infant formula remains low among infants aged 0-36 months in Shanghai.

ObjectiveTo investigate the pollution level of deoxynivalenol （DON） in wheat flour and its products sold in Shanghai， and to assess the health risks of DON exposure for residents in Shanghai who ingested DON from wheat flour and its products. MethodsRisk monitoring data of DON in wheat flour and its products sold in Shanghai from 2017 to 2021 were combined with the consumption data of wheat flour and its products by Shanghai residents. A probabilistic assessment method was used to assess dietary exposure of DON in wheat flour and its products. ResultsThe overall detection rate of DON in wheat flour and its products was 77.3% （1 041/1 347）， with a mean concentration of 226.3 μg·kg-1， P50 of 130.0 μg·kg-1 and a maximum value of 3 080.0 μg·kg-1. The mean daily exposure and 95th percentile daily exposure （by body weight） of DON from wheat flour and its products in Shanghai residents were 0.279 μg·kg-1 and 1.146 μg·kg， accounting for 27.9% and 114.6% of the daily tolerable intake of DON TDI， 1 μg·kg， respectively. The probability assessment results indicated that 6.1% of the whole population in Shanghai had DON exposure exceeding the TDI value. Among them， 12.8% of the population aged 6 years old and below， 16.4% of the population aged between 7 and 17 years old， 3.9% of the population aged between 18 and 59 years old and 3.2% of the population aged 60 years old and above exceeded the TDI value for daily DON exposure through wheat flour and its products. ConclusionCertain populations in Shanghai may face certain health risks from daily DON intake wheat flour and its products. Special attention should be paid to the health risk of daily DON exposure through wheat flour and its products for individuals age below 18 years old .

RESUMO
Aim To investigate the effect of icariin ( ICA) on renal interstitial fibrosis in SHR and explore its mechanism. Methods Fourteen male SHR of 13-week-old were randomly divided into model group( n=7 ) and ICA group ( n=7 ) , and WKY as control group (n=7). One week after adaptive breeding,the rats in the ICA group were given ICA 40 mg·kg-1,ig,bid to 26-week-old. The other rats in the model group and control group were given the same amount of normal sa-line. Then, the morphological changes of the kidney were observed by HE and Masson staining,respective-ly. The contents of plasma aldosterone andⅢcollagen were measured by double antibody sandwich method. The mRNA expressions of TGF-β1 , Smad2 , CTGF and FN were examined by real time RT-PCR. Results Compared with the normal control group, the kidney structures of model group were disordered,the mesang-ial matrix and the tubular interstitial fibrosis were in-creased. The contents of plasma aldosterone and Ⅲcollagen were increased in model group ( P <0. 01 ) . And the mRNA expressions of TGF-β1 , Smad2 , CTGF and FN in kidney tissues were up-regulated in model group( P <0. 01 or P <0. 05 ) . Compared with the model group,the kidney structures were improved and the contents of plasma aldosterone and Ⅲ collagen were reduced, as well as the mRNA expressions of TGF-β1,Smad2,CTGF and FN in kidney tissues were down-regulated(P<0. 01 or P<0. 05)in ICA group. Conclusion ICA may have anti-renal interstitial fi-brosis effect on SHR,and the mechanism might be re-lated to the reduced plasma aldosterone levels and the down-regulated expression of TGF-β1 and Smad2 .
