ABSTRACT
OBJECTIVE To analyze the chemical components and components migrating to the blood of Jianpi huazhuo tiaozhi granules （JHTG）. METHODS SD rats were divided into a control group and a medication group， with 6 rats in each group. The medication group was given JHTG 3 mL. Sixty minutes after medication， the serum samples of the 2 groups were collected， and the chemical components and components migrating to the blood of JHTG were separated by ultra-high performance liquid chromatography-tandem mass spectrometry （UPLC-MS/MS） and mass spectrometry data were collected. Combined with the overall scheme of UNIFI natural products， based on the 6400 natural product theory mass spectrometry database， the structure was analyzed and confirmed by literature review and reference substance comparison. RESULTS & CONCLUSIONS A total of 130 components were identified from JHTG， including 3 in Codonopsis Radix， 13 in Nelumbinis Folium， 15 in Poria， 5 in Atractylodis Macrocephalae Rhizoma， 9 in Citri Reticulatae Pericarpium， 1 in Coicis Semen， 19 in Alisma Rhizoma， 24 in Salviae Miltiorrhizae Radix et Rhizoma， 7 in Hordei Fructus Germinatus， 24 in Crataegi Fructus， 2 in Amomi Fructus， and 3 in Aucklandiae Radix. In addition， quercetin and quercetin-3-O-β-D-glucopyranoside， kaempferol and citric acid may originate from Nelumbinis Folium or Crataegi Fructus， while oleanolic acid may originate from Poria or Crataegi Fructus. By comparing the reference substances， 8 components were finally determined （pachymic acid， atractylenolide Ⅱ， alisol A， alisol B， alantolactone， bornyl acetate， salvianolic acid A， salvianolic acid C）. A total of 72 prototype components such as quercetin and kaempferol were identified， mainly including flavonoids， terpenoids， lignans and phenolic acids. A total of 11 metabolites such as （NATCM’s Project of High- dehydroanonaine and 16-O-acetylpachymic acid were level Construction of Key TCM Disciplines）identified， mainly terpenoids. Metabolic pathways include phase Ⅰ metabolic reactions such as dehydrogenation and dehydroxylation， and phase Ⅱ metabolic reactions such as methylation and acetylation.
ABSTRACT
ObjectiveTo evaluate the overall demand for rehabilitation services from the perspective of the groups with disabilities, diseases, injuries and older adults, and explore the causes of the supply and demand gap of rehabilitation services. MethodsThe literatures in the field of rehabilitation were collected, summarized and analyzed, including policy documents issued by World Health Organization and relevant departments in China, surveys, and researches. ResultsThe demand for rehabilitation services caused by disabilities, chronic diseases, injuries and population ageing were vast in China, but many were still unmet. The main reasons leading to the gap included those population trend and health situation, the insufficient reserve of rehabilitation resources coming from incomplete development of rehabilitation service system early, and inadequate construction of disability reporting system, which could not efficiently meet rehabilitation demand with supply. ConclusionThe strategies to optimize the rehabilitation services system and promote the quality of the services based on the disability reporting system are warranted.
ABSTRACT
Objective:To observe the effect of goal-oriented management of continuous monitoring of regional cerebral oxygen saturation (rSO 2) on early postoperative neurocognitive disorders (PND) in elderly spinal surgery patients. Methods:From November 2018 to July 2019, 60 patients undergoing posterior lumbar interbody fusion in the Second Hospital of Shanxi Medical University were selected and randomly divided into control group and intervention group, 30 cases in each group. RSO 2 was recorded before anesthesia induction (T 0), 10 min after anesthesia induction (T 1), 10 min after prone position (T 2), 10 min after spinal decompression (T 3), 30 min after spinal decompression (T 4) and 10 min after extubation (T 5); The basic value of rSO 2, the minimum value of rSO 2 (rSO 2min), the average value of rSO 2 (rSO 2mean) and the maximum percentage of decrease of rSO 2 (rSO 2% max) were recorded. When rSO 2 <55% or rSO 2% max >10% and the duration was longer than 15 s, the intervention group took measures such as adjusting head position, adjusting blood pressure, increasing FiO 2 and respiratory parameters, increasing P ETCO 2 until rSO 2 returned to the required range; The control group did not interfere with the intraoperative rSO 2. Neuropsychological tests were used to evaluate the cognitive function of the two groups 7 days after operation. The patients were followed up 30 days after operation with the revised cognitive function telephone questionnaire (TICS-M). The incidence of postoperative neurocognitive impairment (PND) was recorded. The perioperative data and postoperative adverse reactions of the two groups were recorded. Results:At T 3 and T 4, the rSO 2 of the intervention group was significantly higher than that of the control group ( P<0.01), the intraoperative rSO 2min and rSO 2mean of the intervention group were higher than the control group, and the rSO 2%max was lower than the control group ( P<0.05). The incidence of PND 7 days after surgery, extubation time, postanesthesia care unit (PACU) stay time, hospital stay and postoperative adverse reactions in the intervention group were lower than those in the control group ( P<0.05). There was no significant difference in the incidence of PND 30 days after operation between the two groups ( P>0.05). Conclusions:The goal-oriented management of rSO 2 can reduce the incidence of early postoperative PND in elderly spine surgery patients, which is conducive to the rapid recovery of patients after surgery.
ABSTRACT
Objective:To evaluate the outcome of endoscopic submucosal dissection (ESD) of colorectal tumors, and to analyze the factors affecting the therapeutic efficacy of ESD.Methods:Clinical data of patients with colorectal tumors who were treated with ESD in Department of Gastroenterology in Beijing Hospital from November 2016 to December 2019 were reviewed. A total of 82 patients with pathologically confirmed colorectal adenoma or carcinoma of diameter ≥20 mm were included. The clinical features, ESD and pathological outcomes of the patients were analyzed.Results:All 82 lesions were single, with the mean diameter of 29.72±10.74 mm. Lesions were divided into the laterally spreading tumors (LST), mainly located in the ascending colon and ileocecal region (47.8%, 22 / 46) and the protruding colorectal tumors, mainly located in the left colon, 52.8% (19 / 36) of which were located in the sigmoid colon. The overall resection rate was 81.7%(67/82) and the curative resection rate was 72.0%(59/82). The incidences of bleeding and perforation were 2.4%(2/82) and 1.2%(1/82), respectively. The curative resection rates [91.4%(32/35), 63.6%(7/11) and 55.6%(20/36), P=0.003] and surgical operation rates [8.6%(3/35), 18.2%(2/11) and 36.1%(13/36), P=0.010] of LST-G, LST-NG and protruding colorectal tumors were significantly different. Multivariate regression analysis showed that protruding colorectal tumor ( OR=3.396, 95% CI: 1.014-11.374, P=0.047) and submucosal severe fibrosis (F2 type) ( OR=5.508, 95% CI: 2.216-13.692, P=0.001) were independent risk factors for non-curative ESD resection of colorectal tumors. Conclusion:ESD is effective and safe for colorectal tumors of diameter ≥ 20 mm. However, there are some differences in the rate of submucosal invasion and treatment outcome among different types of lesions. The risk factors for non-curative resection are protruding tumors and severe submucosal fibrosis.

OBJECTIVE: To compare the diagnostic value of high-k V X-ray chest photography and chest high-resolution computed tomography( HRCT) in the diagnosis of pulmonary thesaurosis induced by dust of iron and its compounds(hereinafter called the iron pulmonary thesaurosis). METHODS: A total of 80 workers exposed to iron oxide dust in a magnetic material factory were collected as the study subjects by convenience sampling method,and they were examined with high-k V X-ray chest photography and HRCT. Differences between the two methods in the diagnosis of iron pulmonary thesaurosis were compared. RESULTS: Of the 80 workers,only 5 of them(6. 2%) showed no abnormal changes in chest HRCT,others showed varying degrees of diffuse distribution of air-cavity nodules and ground-glass lesions. High-k V X-ray chest photography and chest HRCT diagnosis of iron pulmonary thesaurosis accounted for 8. 8%( 7/80) and 37. 5%(30/80) with extreme mild degree,and 21. 3%(17/80) and 26. 3%(21/80) with mild degree respectively. The diagnostic rates for iron pulmonary thesaurosis were 30. 0%( 24/80) and 63. 8%( 51/80),respectively. There was consistency between the two methods for the diagnosis of iron pneumoconiosis( Kappa = 0. 411,P < 0. 01). The chest HRCT has a higher diagnostic classification and diagnosis rate compared with the high-k V X-ray chest photography( P <0. 01). CONCLUSION:s The chest HRCT has a higher diagnostic grade and higher diagnostic rate for lung siderosis compared with the high-k V X-ray chest photography,which is helpful for the early diagnosis of the disease.
ABSTRACT
Objective To explore the current training programs for preventive medicine undergrad-uates in China's colleges and universities, so as to provide more clues for further optimizing the training program. Methods Twelve colleges and universities were selected in accordance with the stratification of 985, 211 and general colleges and universities and their training programs for preventive medicine under-graduates were collected in February, 2016. By comparing with the requirements of "The directory and introduction of undergraduate courses in colleges and universities (2012)" and the spirit of the second round of "undergraduate teaching evaluation of higher education institutions", training programs were described; t test and multivariate analysis of variance were used to compare differences among different levels of colleges and universities;SPSS 21.0 was used for statistical processing. Results In some colleges and universities, training programs were still not concrete and the setting of three common core courses (Health Education, Health Service Management and Women's Health Science) did not meet the require-ments of the new directory of 2012. All selected colleges and universities had established their standards of the minimum curricular credits ( including course system and internship practical training ) which were(245.33±27.01) credits. In course system, the required course and the elective course were (176.25±18.46) credits, (26.62±12.68) credits, respectively. The percentage of preventive medicine in required courses was relatively lower, only (21.99 ±3.50)％. In internship and practical training, the clinical practice and the specialty practice were (20.00 ±5.13) weeks, (27.33 ±7.78) weeks, taking (16.46 ±7.75) credits, (23.50 ± 9.86) credits, respectively. No differences were found in courses setting, credits distribution among 985, 211 and general universities and colleges, all P>0.05. Conclusion There still exist problems: training pro-grams are not concrete and the training system cannot fully reflect training objectives in some colleges and universities, needing to be further standardized and improved.
ABSTRACT
Objective To assess the effectiveness and safety of paclitaxel-coated balloons for in-stent restenosis in patients aged 65 years and over.Methods Sixty elderly patients(≥65 years old)with in-stent restenosis were enrolled at the Department of Cardiology,the First Affiliated Hospital of Inner Mongolian Medical University.Based on different treatment methods for in-stent restenosis,patients were divided into the drug-eluting balloon(DEB,n=32)group and the drug-eluting stent(DES,n=28)group.The primary end point was late luminal loss,determined by angiography.Secondary end points included rates of restenosis and major adverse cardiac events (MACEs).Results Quantitative coronary angiography revealed no significant differences in baseline data At 3 months after treatment,the rate of MACEs was 28.6％ in the DES group and 12.5％ in the DEB group(P＜0.05).At 6 months after treatment,angiography showed that the (x)±s of insegment late luminal loss was(0.21±0.04)mm in the DES group versus(0.12±0.06)mm in the DEB group(P ＜0.05).Furthermore,7 of 28 patients (25 ％) in the DES group had restenosis,compared with 4 of 32 patients (12.5 ％)in the DEB group(P =0.03).Conclusions Paclitaxel-coated balloons for coronary in-stent restenosis in patients aged 65 years or over can significantly reduce the incidence of restenosis and lower the rate of MACEs.The procedure is safe with no serious complications,eliminates the need for additional stent implantation,and should be further assessed in future clinical trials.

ABSTRACT
Objective To investigate the clinical significance and distribution of different rotational displacements on the sagittal plane in unstable pelvic fractures radiologically.Methods We retrospectively reviewed 82 patients with unilateral pelvic fracture who had been treated at our department from June 2005 to June 2015.They were 48 men and 34 women,with an average age of 43 ± 18 years.By Tile classification,there were 48 cases of type B and 34 cases of type C.Their rotational displacements on the sagittal plane of the pelvic ring were determined on the anteroposterior X-ray films of the pelvis by measuring the changed distances from the top of iliac crest to the lowest point of ischial tuberosity and to the pubic tubercle.The data were recorded for analysis of different displacements and their clinical significance.Results Of all the 82 patients,based on the preoperative radiographic evidence,36 (43.9％) showed sagittal plane rotational displacement.Of them,28 (77.8％) showed supination displacement and 8 (22.2％) pronation displacement.The preoperative CT three-dimensional reconstruction confirmed the findings from the X-ray films.Twenty-one of the 48 cases of Tile type B (43.8％) and 15 of the 34 cases of Tile type C (44.1％) showed sagittal plane rotational displacement.The success rate of closed reduction was,respectively,66.7％ (24/36) in the 36 cases with sagittal plane rotational displacement,62.5％ (5/8) in those with pronation displacement and 67.9％ (19/28) in those with supination displacement,all significantly lower than the total success rate of closed reduction in this cohort(84.1％).Conclusions The sagittal plane rotational (pronation and supination) displacement of pelvic fracture can be determined by measuring special points and lines on the anteroposterior radiographs of the pelvis.The supination displacement on the sagittal plane is more common.The unstable pelvic fracture with sagittal plane rotational displacement is more difficult to reduce.
