Objective:
To understand school physician in primary and secondary schools in Yichang City, Hubei Province from 2019 to 2020, and to provide a reference for strengthening the school physician team in primary and secondary schools.
Methods:
149 and 102 primary and secondary schools from 6 municipal districts in Yichang City, Hubei Province, were randomly selected in November 2019 and November 2020, respectively, and were administered by questionnaire survey.
Results:
The proportion of school physicians increased from 39.6% in 2019 to 65.7% in 2020. In the past two years, the equipment rate of school physician in both central and fringe urban areas increased, especially the fringe urban areas, number of school physician increased from 38 to 96. A total of 93 and 141 school physicians were selected to pariticipate in questionaire survey in 2019 and 2020 respectively. The survey showed that more than 90% of school physicians in primary and secondary schools in Yichang received training, and 74.5% had college education level. However, most of them lack professional qualification and medical background.
Conclusion
School physician of primary and secondary of Yichang is well development over the past two years, and the proportion substantially increased. However, there is still room for improvement in the quantity and quality of school physicians, and professional qualification needs to be improved. More attention should be paid to the marginal urban areas to achieve a balance between quantity and quality.

Objective To investigate the feasibility and safety of hybrid surgery in treatment of chronic symptomatic internal carotid artery occlusion.MethodsFrom April 2016 to December 2018, 9 patients with chronic symptomatic internal carotid artery occlusion confirmed by digital subtraction angiography were treated with carotid endarterectomy (CEA)+double chamber Fogarty balloon (3F) embolectomy or stent implantation when necessary. The clinical data of these patients were retrospectively analyzed. Vascular recanalization and complications during perioperative period and follow-up of the patients were analyzed.ResultsCEA+double chamber Fogarty balloon (3F) thrombectomy was performed in 5 patients; and stent placement was performed in 4 patients after Fogarty balloon thrombectomy. The internal carotid arteries of all 9 patients were unobstructed immediately during the operation. Postoperative hyperperfusion syndrome occurred in 3 patients; blood pressure was strictly controlled and the symptoms gradually relieved after proper dehydration. No serious complications such as cerebral hemorrhage, cerebral infarction, or nerve injury occurred. The duration of follow-up was 4-36 months; no patient developed a new stroke or death; no re-occlusion appeared; but one mild restenosis (50%) was detected. one patient suffered from a TIA attack 6 months after operation. ConclusionHybrid surgery is an effective method for treatment of chronic symptomatic internal carotid artery occlusion; however, preoperative evaluation and selection of patients should be carefully; individualized treatment plans should be developed.

This study aimed to compare the safety and effectiveness between unilateral biportal endoscopy (UBE) technique and microscopic decompression (MD) technique in lumbar spinal stenosis treatment. PubMed, Cochrane Library, Embase, Web of Science, China National Knowledge Infrastructure, and other databases were used to conduct extensive literature searches. RevMan ver. 5.3 software was used for the statistical analysis. Eleven studies were included with 930 patients, including 449 patients in the UBE group and 521 in the MD group. Both techniques revealed similar operative times at −1.77 minutes (95% confidence interval [CI], −7.59 to 4.05 minutes; p =0.55), the postoperative dural expansion area at −1.27 (95% CI, −19.30 to 16.77; p =0.89), the postoperative complications at 0.76 (95% CI, 0.47 to 1.22; p =0.26), the preoperative Visual Analog Scale (VAS) for leg pain, and the last follow-up (>12 months) VAS for leg pain at −0.04 (95% CI, −0.14 to 0.06; p =0.47), the preoperative Oswestry Disability Index (ODI), and the last follow-up (>12 months) ODI scores at −0.18 (95% CI, −0.76 to 0.40; p =0.54), and patient satisfaction (the modified MacNab score) at 1.15 (95% CI, 0.54 to 2.42; p =0.72). However, intraoperative bleeding was lower following the UBE technique at −52.78 mL (95% CI, −93.47 to −12.08 mL; p =0.01) and was shorter following the UBE technique at −3.06 (95% CI, −3.84 to −2.28; p <0.01). UBE and MD technology have no significant differences in efficacy or safety in the treatment of patients with lumbar spinal stenosis based on this meta-analysis. However, the UBE technique has less intraoperative bleeding and a shorter hospital stay. It has a slight advantage and is a better surgical option than the MD technique. It can be an alternative minimally invasive spinal surgery method.

Objective To establish a direct extraction ultra-high performance liquid chromatography tandem mass spectrometry method for the determination of bongkrekic acid in corn flour. Methods Bongkrekic acid was directly extracted with 80% methanol from corn flour samples, and the supernatant after vortex and centrifugation was determined after passing through membrane filtration. At the same time, the corn flour samples were extracted by solid phase extraction. The determination results of the two methods were compared. Results The linearity of standard series was good within the range of2-20 μg/L, and the linearity coefficient was>0.999. The determination result of the positive sample by direct extraction method was 193.40 mg/kg (n=6). Adding the standard to the blank sample at the levels of 2, 6, and 10 μg/L, the calculated recovery rate was 75.82% - 99.33%, and the relative standard deviation was 3.54 % - 8.45%. The detection limit of the method reached 6 μg/kg. After extraction by solid phase extraction, the determination result of the positive sample was 196.84 mg/kg (n=6). The recovery rate was 77.12% -100.83%, with a relative standard deviation of 8.32% - 9.54%. Conclusion Compared with the solid phase extraction, the direct extraction method for the extraction of bongkrekic acid from corn flour has the advantages of rapidity, simplicity, and cost savings.
