Objective: To evaluate the outcome and postoperative reaction of dural substitute (Neuropatch) applying in the treatment of Chiari I malformation(CMI) associated with syringomyelia(SM). Methods:Forty patients of CMI associated with SM were operated in our department from Jul. 2002 to Jul. 2004. All patients underwent posterior cranial fossa decompression and duraplasty. They were divided into two groups, 20 patients being repaired with Neuropatch (Neuropatch group), and the others with autologous fascia lata (fascia group). There were 6 males and 14 females in Neuropatch group and 10 males and 10 females in fascia group. The operations were performed under general anesthesia via suboccipital approach and the extent of posterior cranial fossa decompression ranged from 20 cm2 (5 cm×4 cm) to 35 cm2 (5 cm×7 cm). The removal of posterior arch of atlas depended on the extent of tonsillar herniation, and the dura was opened in Y shape. The Neuropatch was cut into triangular shape, and the same sized autologous fascia lata was used in fascia group. The patches were sutured tightly to the dura matter in each group. The incision was closed layer by layer and drainage was used, if necessary. Antibiotics and hormone were routinely used. The duration of operation, postoperative fever were evaluated, the outcome of the operation was evaluated by Tator scale, and the data were analyzed with statistic software SPSS 10.0. Results: There were12 patients (60%) who suffered from postoperative fever in the Neuropatch group, and 9 patients (45%) in the fascia group(χ2=0.902,P=0.342). Seventeen patients in each group were improved postoperatively. The duration of operation, postoperative fever and antibiotics used were compared between the two groups. No significant difference was found, but the duration of postoperative fever and the time of hormone used were different. There were no postoperative infections that occurred after the follow up for 1 to 2 years, except for one patient in fascia group who developed infective granuloma and recovered later by treatment. Conclusion: Neuropatch is a useful dural substitute for the repair of dural defects in the treatment of CMI associated with syringomyelia.

Oxidative stress is a redox imbalance in the body, which is one of the important factors leading to tissue damage and diseases. The nuclear factor E2-related factor 2 (Nrf2)-Kelch like ECH-associated protein 1 (Keap1) signaling pathway is not only an important defense system against oxidative damage, but also one of the key signaling pathways of the antioxidant capacity. Numerous studies have shown that targeting the Keap1-Nrf2 signaling pathway to activate Nrf2 has become an effective strategy for the treatment of oxidative stress and related diseases. Using small molecules to directly block the Keap1-Nrf2 protein-protein interaction (PPI) is one of the important directions for activating Nrf2 and exerting the cytoprotective effect, which can avoid the potential side effects of covalent modification of Nrf2. On the other hand, the Keap1 is an efficient E3 ubiquitin ligase that has been used in the design of proteolysis targeting chimeras (PROTACs). This review summarizes the research progresses of Keap1-Nrf2 protein interaction inhibitors and degraders based on the Keap1 E3 ubiquitination system in recent years.

Objective To determine the activities of 131I for treating differentiated thyroid carcinoma with diffuse pulmonary metastases ( DTC-DPM ) from the perspective of internal radiation dosimetry.Methods According to Medical Internal Radiation Dosimetry (MIRD) schema, the activity constraint,from which the whole bdy retention at 48 h should not exceed 2.96 GBq (2.96 GBq rule), was converted to dose-rate constraint(DRC) to lungs at 48 h ( DRCLU ·48 h ) in 131I therapy for DTC-DPM. Based on the assumption of DRCLU·48 h at 48 h in lung, the fractions of whole body activities ( F48 ), the effective half times of 131I in lungs ( TLL ) and the remainder of body ( TRB ) were 0.6-0.9, 20- 120 h, and 10- 20 h, respectively. The maximum safe activities of 131I for different human phantoms from the Organ Level Internal Dose Assessment (OLINDA) software were calculated. Results According to MIRD schema and 2.96 GBq rule, DRCLU ·48 h should not exceed 46.4 mGy/h in 131I therapy for DTC-DPM. Depending on varying F48 h,TLL and TRB, the maximum safe activities of 131I were 6.77-81.36, 5.29-56.20, 5.08-55.19 and 3.87-40. 52 GBq for the male adult, female adult, 15-year-old, and 10-year-old patients with DTC-DPM, respec tively. Conclusion Dosimetry-guided 131I therapy for DTC-DPM considers adequately the differences of 131I kinetics in individual patients and can adjust administered activities of 131I on the precondition of avoiding radiological pneumonitis and pulmonary fibrosis.
