ABSTRACT
OBJECTIVE@#To investigate the feasibility of mimics software in analyzing a new type of complex anterior cervical fixation -- anterior transpedicular screw fixation+zero notch internal fixation.@*METHODS@#From January 2021 to September 2022, 50 normal pedestrians who underwent cervical spine CT scanning were selected for C1-C7 segment scanning, including 27 males and 23 females, aged from 25 to 65 years old with an average of (46.0 ± 9.0) years old. The dicom format is exported and engraved into the CD, and use the mimics software to perform 3D reconstruction of each segment. A simulated screw is placed on the image according to the critical value of zero notch screw (head and tail angle 44°, internal angle 29°). The position of zero notch screw in each segment is observed to determine the feasibility of anterior transpedicular screw fixation plus zero notch internal fixation.@*RESULTS@#For the upper zero notch screws the three-dimensional images of the cervical spine across all 50 subjects within the C3-C7 segments demonstrated safe position, with no instances of intersection with ATPS. For the lower zero notch screw, in C3-C4 and C4-C5, 4 out of 50 subjects are in the safe position in the three-dimensional images of cervical vertebrae, and 46 cases could achieve secure screw placement when the maximum caudal angle is(32.3±1.9) ° and (36.1±2.2) °, respectively. In C5-C6 and C6-C7 segments, no lower zero notch screws intersected with ATPS, and all screws are in safe positions.@*CONCLUSION@#Lower cervical anterior pedicle screw fixation plus zero notch internal fixation can achieve successful nail placement through the selected entry point and position.

ABSTRACT
OBJECTIVE@#To observe the efficacy of early treatment of suspension moxibustion for Bell's palsy and its influence on the prognosis, and to explore whether the early treatment of suspension moxibustion has non-inferiority effect to hormone treatment and whether suspension moxibustion combined with hormone treatment has the synergistic effect.@*METHODS@#A total of 132 patients with acute-stage Bell's palsy were divided into a hormone group (94 cases) and a moxibustion group (38 cases) by non-random method, and the hormone group was further randomly divided into a hormone with moxibustion group (48 cases) and a hormone without moxibustion group (46 cases). The acupuncture and oral administration of mecobalamin capsule were used as basic treatment. Acupuncture was applied at Yangbai (GB 14), Sibai (ST 2), Quanliao (SI 18), Dicang (ST 4), Jiache (ST 6), Yifeng (TE 17), etc., with the needles retained for 30 min, once a day, 5 consecutive days per week; there was an interval of 2 days between two weeks, and a total of 4-week treatment was given. The oral administration of mecobalamin capsule was given 0.5 mg each time, 3 times a day for 4 weeks. The patients in the moxibustion group, on the basis of basic treatment, were treated with the suspension moxibustion at Yangbai (GB 14), Sibai (ST 2), Dicang (ST 4), Jiache (ST 6), Wangu (GB 12), Yifeng (TE 17) of affected side, 5 min per acupoint, once a day, 5 consecutive days per week; there was an interval of 2 days between two weeks, and a total of 4-week treatment was given. The patients in the hormone without moxibustion group, on the basis of basic treatment, were treated with prednisone acetate tablets. The patients in the hormone with moxibustion group, on the basis of basic treatment, were treated with suspension moxibustion and prednisone acetate tablets. All the treatment was given for 4 weeks. The House-Brcackmann facial nerve grading (H-B) global score and facial disability index (FDI) scale were used to evaluate the curative effect in the three groups before treatment, 2 weeks and 4 weeks into treatment and 4 weeks after treatment; the efficacy was compared among the three groups.@*RESULTS@#Compared before treatment, the H-B grading and FDI scores were significantly improved 2 weeks and 4 weeks into treatment and 4 weeks after treatment (0.05); the H-B grading and FDI scores in the hormone with moxibustion group were superior to those in the moxibustion group and the hormone without moxibustion group 4 weeks into treatment and 4 weeks after treatment (0.05). At the end of follow-up, the cured rate in the hormone with moxibustion group was 81.3% (39/48), which was superior to 68.4% (26/38) in the moxibustion group and 60.9% (28/46) in the hormone without moxibustion group (0.05).@*CONCLUSION@#The three treatment methods are all safe and effective for acute-stage Bell's palsy. The suspension moxibustion combined with hormone therapy are superior to suspension moxibustion or hormone therapy alone. Early treatment of suspension moxibustion is safe and effective for Bell's palsy, and has obvious synergistic effect with hormone. For the patients who cannot use hormone, suspension moxibustion could replace hormone, which is non-inferior to hormone.
ABSTRACT
Objective To investigate the association between maternal food group intakes during pregnancy and the risk of infantile eczema in a Chinese population. Methods A prospective birth cohort study was conducted and 523 women were recruited at 20-28 weeks of pregnancy in Guangzhou from 2017 to 2018. A validated 81-item quantitative food frequency questionnaire was used to assess maternal dietary intakes during the past month. Food items were divided into ten food groups according to the Chinese Dietary Guidelines. Offspring were followed up at 6 months by the symptom questionnaire of eczema. Multivariate Logistic regression model was conducted to evaluate the association between maternal food group intakes during pregnancy and the risk of infantile eczema. Results The cumulative incidence of eczema at 6 months was 51.8%. Maternal consumption of poultry was higher in the eczema group (27.62±25.20 g/d) than the control group (22.03±22.63 g/d, P=0.022). Comparing to the lowest quantile (Q1), higher maternal intake of poultry (Q4) and fish (Q3) were significantly associated with an increased risk of infantile eczema (OR=2.71, 95% CI=1.24-4.81; OR=2.38, 95% CI=1.23-4.59, respectively) after multivariate adjustment. Conclusion Higher intakes of poultry or fish during pregnancy were associated with an increased risk of infantile eczema in Chinese population.
ABSTRACT
Chorismate synthase(CS, EC:4.2.3.5) catalyses 5-enolpyruvy-shikimate-3-phosphate to form chorismate, which is the essential enzyme for chorismate biosynthesis in organisms. The amino acid sequences of CS from 79 species of higher plants were reported in GenBank at present. 125 amino acid sequences of CS from Baphicacanthus cusia and other 78 species of plants were predicted and analyzed by using various bioinformatics software, including the composition of amino acid sequences, signal peptide, leader peptide, hydrophobic/hydrophilic, transmembrane structure, coiled-coil domain, protein secondary structure, tertiary structure and functional domains. The phylogenetic tree of CS protein family was constructed and divided into eight groups by phylogenetic analysis. The homology comparison indicated that B. cusia shared a high homology with several plants such as Sesamum indicum, Nicotiana tabacum, Solanum tuberosum and so on. The open reading frame(ORF) of all samples is about 1 300 bp, the molecular weight is about 50 kDa, the isoelectric point(pI) is 5.0-8.0 which illustrated that CS protein is slightly basic. The ORF of CS we cloned in B. cusia is 1 326 bp, the amino acid residues are 442, the molecular weight is 47 kDa and pI is 8.11. The CS in B.cusia showed obvious hydrophobicity area and hydrophilicity area, no signal peptide, and may exists transmembrane structure areas. The main secondary structures of CS protein are random coil and Alpha helix, also contain three main structural domains which are an active structural domain, a PLN02754 conserved domain and a FMN binding site. The acquired information in this study would provide certain scientific basis for further study on structure-activity relationship and structure modification of CS in plants in the future.
