Objective To study the clinical effect of qi supplementation combined with rehabilitation on the severity of fatigue after ischcmic stroke in patients with qi deficiency. Methods Ninety ischemic stroke patients with qi deficiency were randomly divided into 3 groups of 30. The treatment group was treated with an oral decoction of qi-supplementing Chinese medicine and also rehabilitation. The Western medicine control group was treated with a Chinese medicine placebo, Western medicine and rehabilitation. The blank control group was treated with the Chinese medicine placebo and rehabilitation. All groups were evaluated using a stroke-specific quality of life scale ( SSQOL) and a fatigue severity scale (FSS) before and 4 weeks after treatment. Results After treatment, the average SS-QOL and FSS scores had improved significantly compared with those before treatment, especially in the two treatment groups. There was a significant difference between the treatment group and the Western medicine control group,and between the treatment group and the blank control group on both scales. There was also a significant difference between the Western medicine control group and the blank control group in terms of SS-QOL scores, but not FSSscores. Conclusion All 3 treatments alleviated fatigue in ischemic stroke patients with a qi deficiency. Qi supplementation combined with rehabilitation was the most effective, followed by Western medicine combined with rehabilitation.

OBJECTIVETo assess the therapeutic strategies and risk factors of malignant fibrous histiocytoma of soft tissue.

METHODSThe 78 cases with malignant fibrous histiocytoma of soft tissue treated at Muscular Skeletal Tumor Center of People's Hospital, Peking University from December 1999 and October 2010 were retrospected. Univariate and multivariate analyses were performed to determine the probable risk factors including sex, age, tumor location, tumor size and so on.

RESULTSAll 60 cases were followed up ranged from 6 to 131 months (medium 35.5 months). The 1-, 3-, 5-year overall survival rate was 84.9%, 72.9% and 56.9% respectively. Local recurrence rate is 33.3% (20 cases) with a median time of 11.5 months (1 to 72 months) and metastatic rate is 15.0% (9 cases) with a median time of 7 months (1 to 26 months). Univariate analysis indicated that condition of presentation (primary case or recurrence case), tumor size and surgical margin were significantly related to survival rate (all P < 0.05, Kaplan-Meier Log-rank test), surgical margin and radiotherapy related to local recurrence rate (P value were 0.000 and 0.039 respectively), and surgical margin related to metastatic rate. Multivariate analysis showed that surgical margin was independent risk factors for survival rate (P = 0.002, OR = 5.753, 95%CI 1.904 - 17.386) and local recurrence rate (P = 0.000, RR = 0.044, 95%CI 0.010 - 0.188).

CONCLUSIONSSurgical margin was independent risk factors for survival rate and local recurrence rate. Comprehensive therapy of surgery followed by radiotherapy can improve survival rate, reduce local recurrence rate.

To investigate the impact of respiratory movement to determine the target volume on cone beam CT (CBCT) for lung tumor, we used CIRS dynamic thorax phantom (Model-CIRS008) to simulate the sinusoidal motion of lung tumor. With a constant amplitude, the ratio of the time of near-end-expiratory and near-end-inspiratory (E/I) changed when it was scanned with CBCT. We analyzed the contrast changes of target by extracting the CT value of each pixel on the center line of the target movement direction. The targets were contoured with region growing method and compared with the motion volume generated by the tumor trajectory method. The result showed that the contrast of near-end-expiratory increased and the contrast of near-end-inspiratory decreased with increasing E/I. The contoured volume generated by region growing method decreased with increasing E/I. When E/I = 4, the amplitude A = 1 cm, diameter of 1 cm and 3 cm target volumes were reduced by 48.2% and 22.7%. The study showed that CBCT was not suitable to be used to accurately determine the range of lung tumor movement. The internal target volume (ITV) may be underestimated in CBCT images.

OBJECTIVE: To explore the clinical evaluation system reflecting the superiority and characteristics of comprehensive traditional Chinese medicine (TCM) therapy for acute stroke. METHODS: A randomized controlled trial with single blind in various therapeutic centers was applied on the patients with the acute stage of hemorrhagic stroke due to hypertension, who were allocated to the trial group and the control group. The trial group accepted the general Western medicine therapy and differential treatment of traditional Chinese medicine based on stage classification. Patients in the control group were treated with the general Western medicine and the placebo of traditional Chinese herbal medicine. The treatment effect was assessed at the 7th day, 14th day, 21st day, and 28th day of post-treatment and after 3-month follow-up. The clinical evaluation system included the syndromes of TCM (ZH), Glasgow coma standard (GCS), nerve functional failure (NF), activity of daily living (ADL), Barther index (BI), quality of life index (QLI) and functional activities questionnaire (FAQ). RESULTS: Four hundred and four patients with acute stroke were included. There were 178 cases with yang-syndrome and 21 cases with yin-syndrome in the trial group (n=199), and there were 165 cases with yang-syndrome and 40 cases with yin-syndrome in the control group (n=205). The rates of recovery and obvious improvement after 3-month treatment in the trial group and the control group were 86.5% and 73.6% respectively. There was significant difference between the two groups (P<0.01). The response sensitivity of the effect items indicated that the sensitivity of GCS began to increase from the 7th day and was high at the 14th day and the 21st day for all patients. The response sensitivity of the NF scale was high for all patients at the 14th day, the 21st day and the 28th day. The BI scale and the QLI scale were sensitive to the patients with light and middle stage of stroke at the 21st day, and were sensitive to the patients with light stage of stroke after 3-month follow-up. The FAQ scale was sensitive to the light stroke at the 21st day and after 3-month follow-up. The ADL scale was sensitive to all patients at the 28th day and the patients with light stage of stroke after 3-month follow-up. The ZH scale was sensitive to all patients from 0 to 7d, the 14th day, and the 28th day. The principle components analysis indicated these 7 items could reflect the condition of stroke from 0-7d, the 21st day and after 3-month follow-up, and could be used to evaluate the therapeutic effect of hemorrhagic stroke. ZH scale and FAQ scale were more sensitive than other effect items at the 28th day. CONCLUSION: The seven items (GCSbNFbBIbQLIbFAQbADLbZH) have high sensibility to all patients in the acute stage of hemorrhage stroke especially at the 21st day. The ZH score will change in accord with the condition of stroke, and is appropriate to reflect the condition of stroke. It is believed that the seven items can form the system of effect evaluation in different stages of stroke, and the ZH scale is a very important item.

Objective:To study the relationship between the dynamic changes of angiopoietin-2 (Ang-2) and surfactant protein D (SP-D) in pediatric acute respiratory distress syndrome (pARDS) and the severity and prognosis of the disease.Methods:Using nested case-control study method, 80 children with pneumonia complicated with pARDS admitted to PICU at Fujian Maternal and Child Health Hospital from June 2018 to May 2021 were selected as pARDS group, and 19 healthy children with corresponding age were selected as control group.According to the oxygenation, the children in pARDS group were divided into three subgroups: mild group (23 cases), moderate group (32 cases) and severe group (25 cases). According to the prognosis at discharge, the children in pARDS group were divided into survival group (67 cases) and death group (13 cases). Ang-2 and SP-D were detected by enzyme-linked immunosorbent assay.The levels of Ang-2 and SP-D in children with pARDS of different severity on the first day were compared; The changes of Ang-2 and SP-D levels on the 1st, 3rd and 8th day of children in survival group and death group were compared, and the receiver operating characteristic (ROC) curve was plotted to compare the predictive value of Ang-2 and SP-D for pARDS prognosis.Results:(1) The levels of Ang-2 and SP-D on the first day in pARDS group were significantly higher than those in control group( P<0.001). (2) The levels of Ang-2 and SP-D on the first day in children with pARDS of different severity levels were significantly different ( P<0.001), and the levels of Ang-2 and SP-D increased gradually with the increase of disease severity.(3) The levels of Ang-2 and SP-D in death group were significantly higher than those in survival group on the 1st, 3rd and 8th day ( P<0.05). (4) Prognostic efficacy of Ang-2 and SP-D levels in pARDS group at different time points: when the areas under the ROC curve predicted by Ang-2 on the 1st, 3rd and 8th day for inpatient mortality in children with pARDS were 0.808, 0.981 and 0.989, respectively; the optimal cut-off values were 6 000 pg/mL, 6 971 pg/mL and 4 171 pg/mL, respectively; the sensitivity was 84.6%, 92.3% and 92.3%, respectively; and the specificity was 76.1%, 97.0% and 98.5%, respectively.The areas under the ROC curve predicted by SP-D on the 1st, 3rd and 8th day for inpatient mortality in children with pARDS were 0.689, 0.993 and 0.983, respectively; the optimal cut-off values were 13544 pg/mL, 16003 pg/mL and 12294 pg/mL, respectively; the sensitivity was 84.6%, 100.0% and 100.0%, respectively; and the specificity was 46.3%, 98.5% and 97.0%, respectively. Conclusion:Serum Ang-2 and SP-D levels in children with pARDS increase with the aggravation of the disease.The dynamic changes of Ang-2 and SP-D in children with pARDS with different prognosis are different during the course of disease, and monitoring serum Ang-2 and SP-D during the course of disease has a certain predictive value for clinical outcome.
