Objective To establish a five-color flow cytometric immunophenotyping protocol and valuate its clinical application in leukemia and lymphoma. Methods Samples from 73 cases of acute leukemia and 30 cases of lymphoma were analyzed using a comprehensive antibody panel with five-color combination. The antibody combination CD7/CD33/CD19/CD13/CD45 and MPO/cCD79a/cCD3/CD117/CD45,composed of different lineage distinctive and lineage sensitive markers of B, T and myeloid cells, were applied to determine the lineage originality of leukemia and lymphoma celia. The markers used in the second step analysis were based on the findings of the first step. Results Five-color compensation can be performed automatically and easily with the advanced digital compensation program. The results showed that the expression ratio of CD19 in B-ALL was 100% (27/27), cCD79, pesitivity was 92.6% (25/27) and CD7,cCD3 was expressed in all T-ALL cases (8/8). The B-ALL could be staged depending on the expression level of CD34 ,CD10 ,cμ,sIgM and the T-ALL could be dearly staged dependent on the expression level of CD2,CD1a,,CD4,CD4,CD8. The expression ratio of cMPO, CD117 was 89. 5% (34/38) and 81.6% (31/38) in AML respectively, however CD7 was also expressed in 26.3% (10/38) of AML cases. Combined with morphology, immanophenotypes could be used for diagnosing AML with subtyping. The CD19/SSC gating can be used for immunophenotyping of B cell lymphoma with differential diagnosis. The number of robes required was significantly reduced with our panel from 12 tubes of 3-color to 6 tubes of 5-color. Implementation of the five-color protocol had resulted in 20% reduction in reagent costs. Conclusions The application of fivecolor staining protocol significantly improve the sensitivity and accuracy of measurement of immunophenotypes of acute leukemia and lymphoma. It reduces the cost and can be widely applied in the clinical laboratory diagnosis.

ObjectiveTo observe the 2-8 years' follow-up results of percutaneous laser disc decompression(PLDD) on cervical spondylotic radiculopathy,and to identify factors affecting the outcome of PLDD.MethodsEighty-seven patients with cervical spondylotic radiculopathy were treated consecutively by PLDD in our hospital from December 2002 to June 2009,who were followed up for 2-8 years.There were 32males and 26 females,with the mean age of 51.8 years (range,26-74).The results were evaluated according to the Japanese Orthopedic Association's score of cervical spondylotic radiculopathy(JOA 20 score) and numeric rating scales (NRS) after surgery.Two years after the operation,the excellent and good rate of JOA score of patients with different genders,ages and duration of each subgroup will be compared.ResultsThe excellent and good rate were 37.9％,51.7％,65.5％,81.0％,82.8％,80.9％,72.4％ and 72.7％ at 1,3,6months and 1,2,4,6,8 years after operation respectively.Significant difference was found between the time points of 6 months to eight years after operation and that of one month after operation.The NRS score of the pain symptoms at the final follow-up was significantly reduced(P＜0.05).The excellent and good rate of patients whose course of disease (93.3％) was less than 18 months was significantly higher than that of those whose course of disease was over than 18 months(71.4％) two years after operation (P＜0.05).Conclusion The intermediate-term curative effect of PLDD for the treatment of cervical spondylotic radiculopathy is reliable and stable,and the postoperative curative effect may be influenced by patients' duration of disease.

BACKGROUNDTo investigate the prognostic factors of 355 patients with advanced non-small cell lung cancer for researching an individual treatment module.

METHODSFrom March 1988 to October 2000, after diagnosed by histology or cytology and staged by staging examinations, 355 novel advanced NSCLC patients (stage III, 134; stage IV, 221) were enrolled, who were given at least 2-cycle chemotherapy. Response rate and survival were observed and prognostic factors were analysed.

RESULTSOut of 355 patients, 101 got partial response and 147 had stable disease. Response rate was 28.45%, and tumor control rate was 69.86%. Median survival duration was 16 months. The 1-, 2-, 3- and 5-year survival rates were 58.41%, 29.35%, 14.60% and 8.60%, respectively. In the patients with stage IV, median survival duration was 14 months, and 1-, 2-, 3- and 5-year survival rates were 54.62%, 25.59%, 12.70% and 6.73%, respectively. COX multiple variable analysis showed that improved/stable ECOG score (P=0.044 0) and chemotherapy (after second line failure) combined with γ-IFN (P=0.039 0) had prognostic significance.

CONCLUSIONSImprovement of quality of life is quite important in the treatment of advanced NSCLC. Combination with γ-IFN or TAM and radiotherapy of primary tumor may be helpful to improve the survival of patients with stage IV.

BACKGROUNDBone metastasis is very common in lung cancer patients. Metastasis to spine can lead to paralysis and fracture, deteriorate the quality of patient's life. The objective of this study is to investigate the diagnostic values of bone scanning (NBS), MRI, CT and X-ray examination to discover bone meastasis of lung cancer, and the therapy of bone metastasis and the prognostic factors.

METHODSAbout 561 consecutive NSCLC cases were analyzed with NBS and compared with other radiological examinations (MRI, CT and X-ray).

RESULTSOut of the 455 positive patients by NBS, 300 cases were confirmed to be with bone metastases by dynamic follow-up, MRI, CT and X-ray, and 5 cases were false negative.The sensitivity and specificity of NBS was 98.36% and 39.45% respectively. The accuracy of NBS was 71.48%. Among the 305 patients with bone metastases, 23 patients had no records, 138 patients had bone pain, the incidence of asymptomatic bone metastasis was 47.21%. Multivariables analysis showed that asymptomatic bone metastasis, flat bone metastases, therapy with disodium pamidronate were significantly good prognostic factors, respectively (P < 0.05).

CONCLUSIONSA whole body NBS examination is preferred for the staging of NSCLC. NBS is necessary for patients with NSCLC. In order to exclude the possible false positive or false negative diagnosis by NBS, CT or MRI could be selected according to the sites of lesions.

Objective To analyze and compare the pathological changes of lung tissue in mice infected with the novel H7N9 influenza virus and 2009 pandemic H1N1 influenza virus, respectively, and to preliminarily study the mecha-nisms of acute lung injury induced by those virus infection .Methods SPF 6-week old BALB/c mice ( body weight 18-20 g, male∶female=1∶1) (n=3 in each subgroup) were intranasally infected with H7N9 virus and H1N1 virus, respec-tively.The behavior and survival time of mice after virus infection were observed and the survival rates were analyzed .The heart, liver, spleen, lung, kidney, intestines, and brain were collected at indicated time points for histopathological exami-nation using H&E staining .The distribution of virus antigen was detected by immunohistochemistry .The neutrophil infiltra-tion was also observed .The correlation of lung injury with virus replication and host immune responses was analyzed .Re-sults The lung and spleen injury of mice infected with H 7N9 virus was slighter and their survival rate (100%) was high-er than those of mice infected with H1N1 virus.The damages of the lung and spleen in H1N1virus-infected mice were more severe than that in H7N9 virus-infected mice, and all the 10 mice in this group died within 9 days after virus inoculation . The distributions of both the virus antigens were mainly in the bronchial epithelial cells , a few stromal cells and alveolar ep-ithelial cells .The levels of virus replication in the two groups were not significantly different .There were more intense neu-trophil infiltration in the lung and inflammatory response in the H 1N1 virus-infected mice than those in the H7N9 virus-in-fected mice .Conclusions There are some differences of the pathological characteristics and extent of lung injury in the mice infected with H7N9 virus and H1N1 virus, respectively.The virus replication is a precipitating factor but not the deci-sive factor of the lung injury , and there is a close relationship between the host immune responses and acute lung injury .

BACKGROUNDNow the treatment of non-small cell lung cancer (NSCLC) patients with brain metastasis is not a standard program. The aim of this study is to summarize the factors related to survival of patients with brain metastases from NSCLC.

METHODSA total of 111 NSCLC patients with brain metastases (from September 1995-May 2004) were defined as symptomatic group (37 patients) and asymptomatic group (74 patients) according to central nervous system (CNS) symptoms. The patients in the symptomatic group were given whole brain radiation therapy (WBRT, DT 30-40Gy/20f) first, and then received cisplatin-based chemotherapy. The patients in the asymptomatic group were given cisplatin-based chemotherapy first, and then received WBRT. During the treatment, 49 patients received chemotherapy of BCNU or VM-26 irregularly.

RESULTSThe median survival time was 11 months. The 1-and 2-year survival rate was 40.79% and 13.26% respectively. The survival time was not significantly different between the symptomatic group and asymptomatic group. Median chemotherapy of asymptomatic group was 3 cycles (1-6 cycles) before WBRT. Those patients who received 3 or 4 cycles of chemotherapy before WBRT had better survival (P= 0.0188 , P=0.0035). The treatment of BCNU or VM-26 was a benefit factor for survival (P=0.0219) in asymptomatic group. The hematologic toxicity of grade III or IV was not significantly different between the two groups (P > 0.05). The number of brain metastasis (P=0.000), extracranial metastasis (P=0.022) and WHO performance status (P=0.001) were independent prognostic factors.

CONCLUSIONSThe patients with asymptomatic brain metastases receive 3-4 cycles of chemotherapy before WBRT may be reasonable. During the therapy, the patients with administration of BCNU or VM-26 may have survival benefit.

BACKGROUNDIt is well known that more than 40% patients were initially diagnosed with advanced non-small cell lung cancer (NSCLC) with intrapulmonary or/and distant metastasis. However, up to now, the reports about effects of different metastatic sites on survival were limited. The aim of this study is to investigate the clinicopathologic and survival difference by retrospective analysis among sole intrapulmonary metastasis, sole extrathoracic distant metastasis and simultaneous metastasis of lung and other extrathoracic organs for the patients with advanced NSCLC, and to analyze the prognosis-related factors of NSCLC with intrapulmonary metastasis.

METHODSOf the 425 patients with stage IV NSCLC diagnosed by pathology and through staging evaluation and treated at Beijing Cancer Hospital with long follow-up during Oct. 1995 to Dec. 2003, 81 cases had sole intrapulmonary metastasis, 98 cases had sole extrathoracic distant metastasis and 68 cases presented simultaneous lung metastasis and extrathoracic spread. Kaplan-Meier survival curve was performed to estimate the survival of patients with different metastasis, Log-Rank test was used to compare their survival difference, and univariate analysis was used to find prognostic related factors.

RESULTSMedian survival time (MST) and 1-, 2-, 3-year survival rate (SR) for patients with sole intrapulmonary metastasis were 13 months (95% CI: 11-15), 57%, 21%, 7%, respectively; MST was 22 months (95% CI: 18-26) for patients with N1 and/or N2 and 10 months (95%CI: 7-13) for patients with N3 (P=0.001). Among the patients with ipsilateral, contralateral and bilateral intrapulmonary metastasis, difference of MST and 1-, 2-, 3-year SR had no statistical significance (P > 0.05); Survival of patients with sole intrapulmonary metastasis was not significantly different from that of patients with sole brain or bone metastasis (P > 0.05), but was longer than that of patients with simultaneous lung and extrathoracic spread (P=0.021). One way analysis of variance showed that no significant association were found among age, pathologic subtype, differentiation degree or response of first-line chemotherapy and survival of the patients with sole intrapulmonary metastasis (P > 0.05), but sex and invasive status of lymph node (N1/N2 vs N3) were found to influence the survival of the patients (P= 0.018, P=0.001). Further stratified analysis by age showed that invasion of lymph node was independent prognostic factor (P=0.002); whereas for the patients with simultaneous metastasis of lung and distant organs, metastatic numbers (2 vs ≥3) of organ were independent prognostic factor (P=0.013).

CONCLUSIONSNo statistical difference is found among survival of NSCLC patients with sole intrapulmonary metastasis and with sole brain, bone metastasis. Invasive status of lymph node and metastatic number of organ are important prognostic factors for patients with sole intrapulmonary metastasis and simultaneous metastasis of lung and extrathoracic organs, respectively.

Objective The aim of this study is to explore the changes of expression of integrin αvβ3 in bovine u-terine epithelial cells in vitro induced by estrogen or/and progesterone alone or in combination,and to provide a new refer-ence marker for determining bovine uterine receptivity state. Methods RT-PCR was used to analyze the transcriptional changes of αvβ3 expression in bovine endometrium treated by different concentrations of estrogen,progesterone alone or in combination. Results The expression of integrin αvβ3 reached the highest level when the culture medium was added with progesterone at the concentration of 10 -7mg/mL,and the expression of αv and β3 in the 10 -7mg/mL concentration group was significantly higher than that of the control one(P<0.05). Moreover,the expression of αv was highest in the 10 -10 mg/mL E2group,but the expression of β3 was the lowest in that one. In addition,adding with both estrogen and progester-one,the transcriptional level of integrin αvβ3 was significantly higher than that in the control one. The transcriptional level of αv in the treatment group was significantly higher than that in the control group(P<0.05),but the transcriptional level of β3 in this group was not(P>0.05). Conclusions It can be concluded that integrin αvβ3 can be used as a new poten-tial reference marker gene for detecting the bovine uterine receptive status.

ObjectiveTo explore the impact of e-sports activities on adolescents' health based on International Classification of Functioning, Disability and Health (ICF), and conduct a systematic review of health condition and functioning, interventions and outcomes. MethodsThe ICF was used to systematically analyze the physical and mental health and functional impact of adolescents engaging in e-sports activities. Using the keywords and subject heading search method, articles about e-sports, health condition, functioning, functional rehabilitation (intervention) and outcome were searched in CNKI, VIP, Wanfang Database, PubMed, Web of Science and EBSCO from establishment to February, 2022. Systematic review had been adopted for literatures scanning, selection, quality review, and literature synthesis. ICF framework and WHO-FICs coding system were used to analyze the literatures in the fields of e-sport participants' main health condition and health-related conditions, functioning, interventions, and outcomes (health conditions and functioning). Results and ConclusionEight literatures from six countries had been finally included, mainly in the fields of clinical medicine, rehabilitation sciences, sports psychology and rehabilitation psychology. The literatures published mainly after 2015. The average scores on Physiotherapy Evidence Database (PEDro) were 6.88. Using ICF framework, adolescent e-sport participants had main health conditions and functioning at the levels of body, activity and participation, and environment. At body level, the health conditions and functioning involved in the fields of mental function, sensory function and pain, neuromusculoskeletal and motor-related functions, mainly manifested impairments or disorders such as cognitive impairment, emotional disturbance, fatigue, sleep disturbance, depression and anxiety, obesity and musculoskeletal pain. At the individual level, main health conditions and functioning included healthy behaviors (such as sedentary behaviors, insufficient physical activity), diet and malnutrition, and other healthy behaviors. At the level of environment, main factors included support and personal relation, attitudes, services, institutional and policy performance. There were two categories of interventions: interventions at body level, such as physical intervention, psychological intervention; and intervention at activity and participation level, such as social intervention, cognitive-behaviors intervention, social media and moderate-to-high-intensity physical activity. Adolescent participants can get health benefits from interventions in the six dimensions of WHODAS2.0 of cognition, mobility, self-care, getting along with others, life activities, participation and health impact, and specifically manifested improvement in the fields of emotional and cognitive conditions, daily physical activity level, rapidly increasing from light to moderate physical activity; interruption sedentary, increasing in physical activity; enhancement of social relations, accessing to social support; and forming healthy living habits and improving the quality of life and well-being.

ObjectiveTo review the effects of video game intervention on adults motor functioning based on International Classification of Diseases, Eleventh Revision (ICD-11) and International Classification of Functioning, Disability and Health (ICF). MethodsThe literatures about video game therapy and motor dysfunction were retrieved from databases of CNKI, PubMed, Web of Science, and EBSCO, from establishment to June, 2022. The contents of the literatures were analyzed and encoded based on the conceptual framework and coding of ICD-11 and ICF. ResultsSeven articles were included, which were from six countries, involving 59 randomized controlled trials and 2 648 participants, aged 19.8 to 75.4 years, mainly from the fields of medicine, rehabilitation science, video games, exercise interventions and sports science, with publication dates mainly from 2015 to 2021. The intervention types were mainly classified as simple video game, and combination of video game and exercise intervention. The ways of intervention were human-computer interaction, perceptual motor and augmented reality. The intervention scenes were in scene and presentation scene, while the former involved a rehabilitation institution and family environment, and the latter involved a virtual scene and a physical scene. The frequency of interventions was mainly one to five times a week, 20 to 60 minutes a time, for four to 24 weeks. The outcomes of the intervention mainly involved the promoting the recovery of function of joint and bone, improving the static and dynamic balance of gait, increasing muscle strength, improving self-efficacy, reducing anxiety; improving posture control, providing feedback on daily activities; promoting social interaction, increasing social interaction and communication behavior, etc. ConclusionThere are two types of video game interventions: video game alone and video game combined with motor intervention. The video game intervention combines video game and motor intervention through the interaction of virtual sceneries, dynamic activity demonstration and the presentation and feedback of activity goals, to enhance the effectiveness and efficiency of the intervention and improves patients' interest in motor learning. The intervention can be divided into human-computer interaction, perceptual motor and augmented reality. The outcomes of the intervention can be reflected in three aspects: improvement of physical function, promotion of activity and participation, and enhancement of overall function and quality of life.
