OBJECTIVETo explore the value of surgical treatment on spine metastatic tumor.

METHODS31 cases of spine metastatic tumor with severe pain or/and neurological deficit were selected and treated with various operative methods.

RESULTSExcept for 4 cases, all the patients survived from 3 months to 7 years (average 17.6 months). The patients had no complication during treatment. The symptoms and neurological functions recovered with various extent after operation.

CONCLUSIONSSurgical treatment should cautiously be adopted. When the spine metastatic tumor with severe pain and neurological deficit has no response to the conservative methods, the surgical treatment with decompression and internal fixation should be performed to improve the life quality for the patients.

OBJECTIVESTo investigate the diagnosis and treatment cervical disc calcification in children.

METHODS13 children with cervical disc calcification were analysed retrospectively. Cervical pain was observed after influenza in 5 children, suddenly cervical pain in 3, sudden wryneck in 3 cases. Two children with this disease were accidentally found after injury.

RESULTS14 calcifications of cervical disks were found in 13 children. Clinical symptoms disappeared after symptomatic management. Calcification disappeared in 5 months.

CONCLUSIONSCervical disc calcification in children is a kind of benign self-limited disease. Correst understanding of pathophysiologic course of this disease helps to avoid unnecessary surgery.

Objective To investigate the value of ¹⁸F-FDG PET/CT metabolic parameters and metabolic heterogeneity for predicting the expression of human epidermal growth factor receptor 2 (HER2) in patients with gastric cancer. Methods A total of 45 patients with gastric cancer confirmed by surgical pathology between September 2016 and May 2021 were enrolled in this study.All the patients underwent ¹⁸F-FDG PET/CT examination before surgery.The maximum standardized uptake value (SUVmax),metabolic tumor volume (MTV),and total lesion glycolysis (TLG) of primary gastric cancer were measured,and the linear regression slope of MTV corresponding to different SUVmax thresholds (40% SUVmax and 80% SUVmax) was calculated.The absolute value of the slope was deemed to represent the metabolic heterogeneity of primary gastric cancer,termed the heterogeneity index (HI).Univariate and multivariate Logistic regression analyses were conducted to evaluate the correlations of ¹⁸F-FDG PET/CT metabolic parameters and HI with HER2 expression. Results The 45 patients included 10 with positive HER2 expression and 35 with negative result.The MTV (P=0.043) and HI (P=0.048) were lower in the patients with positive HER2 expression than in the patients with negative HER2 expression.The MTV and HI had the optimal thresholds of 12.10 cm³ and 3.71,respectively,which respectively showed the accuracy of 62.2% and 57.8% for predicting HER2 expression.The univariate Logistic regression showed that the tumor differentiation degree,MTV,and HI were correlated with HER2 expression,while the multivariate Logistic regression showed that only the tumor differentiation degree (OR=20.130,95%CI=1.843-219.860,P=0.014) was an independent predictor for HER2 expression.A further stratified analysis of the tumor differentiation degree showed that HER2 expression only varied among different MTV threshold groups in patients with moderately/well differentiated gastric cancer (P=0.031). Conclusions MTV and HI were associated with HER2 expression in gastric cancer,whereas neither played an independent predictive role.Therefore,these factors should be combined with clinicopathological characteristics of patients to jointly guide treatment decisions.

Twenty one flavonoid glycosides were isolated and purified from n-butanol portion of the water extract of A. annua by various chromatographic techniques such as HP-20 macroporous adsorption resin, silica gel, ODS, Sephadex LH-20 gel column chromatography and preparative high performance liquid chromatography. Their structures were identified by analysis of physicochemical properties and spectral data, and determined as axillarin-7-O-β-D-xylopyranosyl-(1→6)-β-D-glucopyranoside (1), orientin (2), apigenin-6-C-β-D-glucopyranosyl-8-C-β-L-arabinopyranoside (3), apigenin-6-C-β-D-galactopyranosyl-8-C-β-L-arabinopyranoside (4), apigenin-6-C-β-L-arabinopyranosyl-8-C-β-D-glucopyranoside (5), apigenin-6-C-α-L-arabinofuranosyl-8-C-β-D-glucopyranoside (6), quercetin-3-O-β-D-glucopyranosyl-(1→2)-β-D-glucopyranoside (7), apigenin-6-C-α-L-arabinopyranosyl-8-C-β-D-glucopyranoside (8), vicenin-2 (9), patuletin-7-O-β-D-glucopyranoside (10), luteolin-6-C-glucopyranoside (11), vitexin (12), kaempferol-3-O-β-galactopyranosyl-(1→2)-β-glucopyranoside (13), quercetin-7-O-β-D-glucopyranoside (14), patuletin-3-O-β-D-glucopyranoside (15), 7-O-methyl-quercetagetin-6-O-β-D-glucopyranoside (16), quercetin-3-O-β-D-glucopyranoside (17), nepitrin (18), rutin (19), kaempferol-3-O-β-sophoroside (20), and patuletin-3-O-rutinoside (21). Compound 1 is a new compound, compounds 2, 4, 6, 7, 10, 11, 13, 15, 16, 18, 20 and 21 are isolated from A. annua for the first time. In the anti-inflammatory assay, compound 1 inhibited the release of IL-6 from LPS-induced RAW264.7 cells to significantly degrees with the high (100 μmol·L^-1), medium (50 μmol·L^-1), low (25 μmol·L^-1) concentration.
