BACKGROUND: Ghildren refractory clubfoot includes idiopathic multiple contracture, untreated idiopathic clubfoot in older children and failure cases of repeated operations. It is very difficult to treat this type of children patients. It has important significance in the exploration of new therapeutic methods.OBJECTIVE: To improve the therapeutic effectiveness of refractory clubfoot in children with Ilizarov method.DESIGN: a self-controlled study.SETTING: Department of Orthopedics, Nanjing Children' s Hospital, Nanjing Medical University.PARTICIPANTS: Totally 3 cases of children idiopathic multiple contracture, 2 cases of idiopathic clubfoot in children aged more than 10 years old without treatment and 6 cases of postoperative recurrent idiopathic clubfoot were admitted by the Department of Orthopedics of Nanjing Children' s Hospital Affiliated to Nanjing Medical University during 1999 to 2000. All cases manifested abnormal ankylosis and shortening deformity in foot.METHODS: Twelve refractory clubfeet in eleven patients were treated with the Ilizarov method. After achilles tendon lengthening and posterior release,kieschner' wires or olive wires with tension were penetrated through multiple planes of the middle lower 1/3 of tibia, calcaneus and the 1st to the 5th metatarsals, which were fixed respectively to external bone fixer of a ring,half-ring or horseshoe shape and connected with each other by multiple screw bars into a three-dimensional external bone fixing set. Plantarflexion, inversion, adduction and shortening deformities were corrected by the adjustment of the distance between each part of the external bone fixing set through extension, compression, and rotation, etc., and navicular and cuboid osteotomy.MAIN OUTCOME MEASURES: All 11 cases were followed up for 2 to 10 years with an average period of 4. 5 years. Indices like foot morphology,talocrural articualr activity range and deformity correction were observed during the follow up.RESULTS: The results were excellent in 5 cases (6 feet), good in 4 cases (4 feet), fair 2 cases(2 feet) according to the Garceau standard scale. The rate of excellent and good clinical results was 83.3%. Mild forefoot adduction was left in 2 feet of 2 cases and quite obvious tarsal articular ankylosis was found in 4 feet of 4 cases; however, there were no significant differences of gait and load bearing between these patients and normal children.CONCLUSION: The Ilizarov technique is a safe and effective method for the treatment of refractory children clubfoot while its indications should be controlled strictly.

Objective:
To evaluate the dietary risk of neonicotinoid insecticides in market-sold vegetables in Guangzhou City, so as to provide insights into ensuring food safety for residents.
Methods:
Forty-five samples of 21 kinds of vegetables were collected from supermarkets and farmer's markets in Guangzhou City from June to September in 2022, and 10 kinds of neonicotinoid insecticides were determined using liquid chromatography-mass spectrometry (LC-MS). The vegetable consumption was obtained through the survey of food consumption and nutrients intake of residents in Guangzhou City. The dietary risk was evaluated by calculating daily exposure and non-carcinogenic risk quotients of neonicotinoid insecticides.
Results:
A total of 27 samples of vegetables were detected with neonicotinoid insecticides, and the detection rate was 60.00%. Among 10 kinds of neonicotinoid insecticides, 6 kinds were identified, including clothianidin, thiamethoxam, imidacloprid, acetamiprid, dinotefuranand and nitenpyram. The detection rates of clothianidin, thiamethoxam and imidacloprid were relatively high (26.67%, 11.11% and 6.67%), and some samples exceeded the standard, with the rate of 4.44%, 2.22% and 2.22%, respectively. The total exposure of neonicotinoid pesticides (IMIRPF) was 3 053.00 ng/g, and the contents and IMIRPF of imidacloprid were the highest in roots and tubers. The daily exposure of imidacloprid, acetamiprid, dinotefuran, clothianidin, thiamethoxam and nitenpyram was 34.58, 3.85, 1.20, 6.87, 7.19 and 0.86 ng/(kg·d). Non-carcinogenic risk quotients of imidacloprid, acetamiprid, dinotefuran, clothianidin, thiamethoxam and nitenpyram was 5.76×10-4, 0.55×10-4, 0.06×10-4, 0.69×10-4, 0.90×10-4 and 0.02×10-4, respectively, which was lower than 1; and the sum of non-carcinogenic risk quotients was 7.98×10-4, which was lower than 1.
Conclusions
The dietary risk of neonicotinoid pesticides is low in 21 kinds of market-sold vegetables in Guangzhou City; however, the contents of neonicotinoid insecticides in some vegetable samples exceed the standard. The supervision of vegetable markets should be strengthened.

Objective To investigate the effects of ch1D1, an anti-CD86 chimeric antibody, on autoreactive B lymphocytes isolated from patients with systemic lupus erythematosus ( SLE) . Methods Flow cytometry analysis was performed to measure the expression of CD86 on the surface of B cells isolated from patients with SLE and to analyze the effects of ch1D1 on the activation of CD4+T cells. The method of magnetic bead sorting was used to separate B cells, NK cells and CD4+T cells from PBMC collected from healthy subjects and patients with SLE for subsequent experiments. Antibody-dependent cell-mediated cyto-toxicity (ADCC) and complement-dependent cytotoxicity (CDC) that were mediated by ch1D1 were meas-ured with LDH release assay. Effects of ch1D1 on the secretion of auto-antibodies and the proliferation of CD 4+ T were detected by ELISA and 3 H -thymidine ( 3 H-TdR) incorporation assay, respectively. Results The levels of CD80 (68. 08±14. 28 vs 46. 10±12. 14, n=24, P<0. 000 1) and CD86 (44. 72±14. 90 vs 13. 99±10. 74, n=24, P<0. 000 1) expressed on the surface of B cells isolated from patients with SLE were significantly higher than those from the healthy subjects, suggesting the abnormal activation of B cells. Com-pared with the negative control group and the murine monoclonal antibody 1D1, ch1D1 was more effective in mediating the ADCC and CDC responses (P=0. 017 2, P=0. 038 8). Activated T cells significantly en-hanced the secretion of auto-antibodies by B cells isolated from patients with SLE. Compared with the nega-tive control group, the enhanced secretion of auto-antibodies was significantly inhibited by treatment with ch1D1 (P=0. 001 9). Moreover, ch1D1 significantly inhibited the proliferation and activation of CD4+T cells induced in patients with SLE (P=0. 002 4, P=0. 049 5). Conclusion ch1D1, the anti-CD86 chim-eric antibody, could effectively mediate the ADCC and CDC responses against autoreactive B cells isolated from patients with SLE, inhibit the secretion of auto-antibodies and suppress the proliferation and activation of auto-reactive CD4+T cells. It might be a potential immunotherapy agent for the treatment of SLE.
