Objective:To investigate the value of serum free light chain(sFLC)and serum calcium ion in the diagnosis and prognosis of multiple myeloma(MM).Methods:Forty patients with MM treated in Henan Provincial People's Hospital from January 2018 to January 2022 were selected as the observation group,and 40 healthy volunteers were selected as the control group.The differences of sFLC-κ,sFLC-λ,sFLC-κ/λ,serum calcium ions,etc between the two groups were compared.Meanwhile,the differences of sFLC-κ,sFLC-λ,sFLC-κ/λ,serum calcium ions,etc in different international staging systems(ISS),chemotherapy efficacy and prognosis patients were analyzed.Results:The levels of sFLC-κ[(98.39±21.19)vs(12.01±4.45)mg/L],sFLC-λ[(210.20±45.54)vs(14.10±5.11)mg/L]and proportions of hypocalcemia(65％vs 0)in the observation group were significantly higher than those in the control group(P＜0.05),while sFLC-κ/λ ratio[(0.44±0.10)vs(0.87±0.12)]and serum calcium ions[(1.98±0.46)vs(2.42±0.40)mmol/L]were significantly lower than those in the control group(P＜0.05).The sFLC-κ,sFLC-λ,the proportion of hypocalcemia and the course of hypocalcemia in ISS stage Ⅲ patients in the observation group were significantly higher than those in stage Ⅰ and Ⅱ patients(P＜0.05),while sFLC-κ/λ ratio,and serum calcium ions were significantly lower than those in stage Ⅰ and Ⅱ patients(P＜0.05).The levels of sFLC-κ[(107.76±21.22)vs(94.67 ±20.11)mg/L],sFLC-λ[(245.54±41.12)vs(205.54±50.22)mg/L]of patients with hypocalcemia in the observation group was significantly higher than those without hypocalcemia(P＜0.05),while the sFLC-κ/λ ratio was significantly lower than those without hypocalcemia[(0.42±0.04)vs(0.47±0.06);P＜0.05].The levels of sFLC-κ[(107.29±20.14)vs(91.11±18.92)mg/L],sFLC-λ[(247.98±42.26)vs(179.29±39.32)mg/L]in patients with ineffective chemotherapy were significantly higher than those in patients with effective chemotherapy(P＜0.05),while the sFLC-κ/λ ratio was significantly lower than those in patients with effective chemotherapy[(0.43± 0.10)vs(0.50±0.09);P＜0.05)].The area under the ROC curve for sFLC-κ,sFLC-λ,sFLC-κ/λ predicting ineffective chemotherapy was 0.803,0.793 and 0.699 respectively,P＜0.05.There was no significant difference in sFLC-κ,sFLC-λ,sFLC-κ/λ ratio,serum calcium ion,hypocalcemia ratio and hypocalcemia course between survival and death patients(P＞0.05).Conclusion:sFLC and serum calcium are related to 1SS stage of MM patients.sFLC level has a certain value to predict the curative effect of chemotherapy in MM patients.However,the prognostic values of sFLC and serum calcium are not yet confirmed for MM patients.

We wished to establish an expert consensus on late stage of critical care (CC) management. The panel comprised 13 experts in CC medicine. Each statement was assessed based on the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) principle. Then, the Delphi method was adopted by 17 experts to reassess the following 28 statements. (1) ESCAPE has evolved from a strategy of delirium management to a strategy of late stage of CC management. (2) The new version of ESCAPE is a strategy for optimizing treatment and comprehensive care of critically ill patients (CIPs) after the rescue period, including early mobilization, early rehabilitation, nutritional support, sleep management, mental assessment, cognitive-function training, emotional support, and optimizing sedation and analgesia. (3) Disease assessment to determine the starting point of early mobilization, early rehabilitation, and early enteral nutrition. (4) Early mobilization has synergistic effects upon the recovery of organ function. (5) Early functional exercise and rehabilitation are important means to promote CIP recovery, and gives them a sense of future prospects. (6) Timely start of enteral nutrition is conducive to early mobilization and early rehabilitation. (7) The spontaneous breathing test should be started as soon as possible, and a weaning plan should be selected step-by-step. (8) The waking process of CIPs should be realized in a planned and purposeful way. (9) Establishment of a sleep-wake rhythm is the key to sleep management in post-CC management. (10) The spontaneous awakening trial, spontaneous breathing trial, and sleep management should be carried out together. (11) The depth of sedation should be adjusted dynamically in the late stage of CC period. (12) Standardized sedation assessment is the premise of rational sedation. (13) Appropriate sedative drugs should be selected according to the objectives of sedation and drug characteristics. (14) A goal-directed minimization strategy for sedation should be implemented. (15) The principle of analgesia must be mastered first. (16) Subjective assessment is preferred for analgesia assessment. (17) Opioid-based analgesic strategies should be selected step-by-step according to the characteristics of different drugs. (18) There must be rational use of non-opioid analgesics and non-drug-based analgesic measures. (19) Pay attention to evaluation of the psychological status of CIPs. (20) Cognitive function in CIPs cannot be ignored. (21) Delirium management should be based on non-drug-based measures and rational use of drugs. (22) Reset treatment can be considered for severe delirium. (23) Psychological assessment should be conducted as early as possible to screen-out high-risk groups with post-traumatic stress disorder. (24) Emotional support, flexible visiting, and environment management are important components of humanistic management in the intensive care unit (ICU). (25) Emotional support from medical teams and families should be promoted through"ICU diaries"and other forms. (26) Environmental management should be carried out by enriching environmental content, limiting environmental interference, and optimizing the environmental atmosphere. (27) Reasonable promotion of flexible visitation should be done on the basis of prevention of nosocomial infection. (28) ESCAPE is an excellent project for late stage of CC management.

OBJECTIVE: To screen the serum differentially expressed proteins of APL in children. METHODS: Serum protein expression profiles from 20 cases of normal healthy controls, and 20 cases of APL patients were detected by iTRAQ (isobaric tag for relative and absolute quantification)labeling coupled with two-dimensional liquid chromatography-tandem mass spectrometry(2DLC-MS/MS), and analyzed by bioinformatics software. S100A8, LRG1 and SPARC were validated by ELISA. ROC was built by SPSS 20.0 software. RESULTS: Analysis identified 83 differentially expressed proteins in APL serum compared with control according to our defined criteria, of which 33 proteins were up-regulated and 50 proteins were down-regulated (P<0.05)．IPA analysis revealed that these differentially expressed proteins were related to the function of Cellular Movement, Immune Cell Trafficking, Hematological System Development and Function, Cell-To-Cell Signaling and Interaction, Tissue Development, and involved in a variety of signalling Pathways, the most representative pathways including LXR/RXR Activation and Acute Phase Response Signaling. S100A8 and LRG1 were found to be elevated and SPARC was markedly down-regulated in serum of childhood APL when compared to the normal controls as examined by ELISA (P<0.05), which was consistent with the iTRAQ result. The overall predictive accuracy of each protein was reflected by the area under the ROC curve(AUC), S100A8,LRG1 and SPARC with ROC areas of 0.841,1.000 and 0.944 respectively. CONCLUSION S100A8,LRG1 and SPARC may be serve as serum candidate biomarkers for pediatric APL.

Objective:To compare the effects of neuromuscular joint facilitation (NJF) or isotonic muscle training on dynamic and static balance in healthy young men. Methods:October, 2019, twelve students of Capital Medical University School of Rehabilitation Medicine (aged 20 to 29) were evaluated the balance indexes of single leg standing on stable support with eyes closing and single leg standing on unstable support with eyes opening with BIODEX Balance Tester, and measured 10-meter walking time and Timed 'Up and Go' Test (TUGT) after non-intervention, NJF ankle joint pattern and ankle flexion and extension. Results:The balance indexes, 10-meter walking time and TUGT were the least after NJF (F > 18.941, P < 0.01). Conclusion:NJF ankle joint model can improve the dynamic and static balance ability of human body more effectively than isotonic contraction training alone.

Objective:To observe the effects of Kinesio Taping and kneepad on position sense of knee in healthy young adult male. Methods:In September, 2019, 20 healthy adult male aged 21 to 27 were selected. They were measured the joint angle error in angle reproduction test, and tested with functional reach test (FRT), 10-meter walking time (10MWT), and Timed "Up and Go" Test (TUGT) under follow four conditions: non-intervention, simple Kinesio Taping, simple kneepad, and both Kinesio Taping and kneepad. Results:For the angle error, it was the most under non-intervention, and the least under simple Kinesio Taping (F = 61.260, P < 0.001). For FRT, there was no significant difference among all the conditions (F = 1.793, P = 0.988). For 10MWT, it was the least under simple Kinesio Taping (F = 23.817, P < 0.001). For TUGT, it was the most under non-intervention (F = 19.865, P < 0.001). Conclusion:Kinesio Taping can improve position sense of knee, as well as walking, without further benefit along with kneepad.

Objective: To reveal the related factors of inhibitors and differences ofhemorrhage and joint disease before and after the production of inhibitors in children with hemophilia A (HA) . Methods: Retrospective analyses of the clinical data of 381 children with HA under the age of 16 registered in the Registration Management Center of Hemophilia in Henan Provincial from January 2015 to August 2018. Results: A total of the 381 children were enrolled with 116 (30.4%) mild, 196 (51.4%) moderate, and 69 (18.1%) severe cases; 54 patients (14.2%) had inhibitors, including 22 high and 32 low titer inhibitors. Positive family history was positively associated with inhibitors[P<0.001, OR=3.299 (95%CI 1.743-5.983) ], and high-intensity exposure was associated with inhibitors[P=0.002, OR=2.587 (95%CI 1.414-4.731) ]. High-intensity exposure was associated with high titer inhibitor production[P=0.001, OR=8.689 (95%CI 2.464-30.638) ], and high-intensity exposure increased the risk of high titer inhibitors in HA patients. After inhibitors occurred in 54 patients with HA, the rates of overall joint annual bleeding (z=-3.440, P=0.001) and traumatic annual bleeding (z=-2.232, P=0.026) increased, but the rates of the annual joint bleeding (z=-1.342, P=0.180) and spontaneous annual bleeding (z=-1.414, P=0.157) remained to be not statistically significant. The joint ultrasound score did not change significantly after the inhibitor information (z=-0.632, P=0.527) . Conclusions: Positive family history and high-intensity exposure could increase the risk of F Ⅷ inhibitors in HA patients, and high-intensity exposure increased the risk of high titer inhibitors. The rates of the overall joint annual bleeding and traumatic annual bleeding increased after the inhibitor information.

Objective To investigate the expression of calpain small subunit 1 (Capn4) in breast cancer and its clinical significance. Methods The cancer tissues and the paraffin-embeded specimens of the corresponding adjacent normal tissues from 12 patients with breast cancer between May 2015 and July 2015 in Shanghai General Hospital were collected. The expression of Capn4 was detected by using immunohistochemistry. The paraffin-embeded specimens of cancer tissues from 70 breast cancer patients in Shanghai General Hospital between January 2009 and September 2011 were also collected. And the expression of Capn4 was detected. The correlation between Capn4 expression level and TNM stage, pathological grade, molecular markers as well as the prognosis of breast cancer was also analyzed. Results The expression of Capn4 in breast cancer tissues was higher than that in the corresponding adjacent normal tissues. The expression level of Capn4 was correlated with TNM stage (P = 0.002), T stage (P = 0.004), N stage (P = 0.004), M stage (P = 0.025), estrogen receptor (ER) status (χ 2 = 4.787, P = 0.029) and survival status (χ 2 = 5.826, P = 0.016). Kaplan-Meier survival analysis revealed that the median survival time in the higher expression of Capn4 group 90 months was shorter than that in the lower expression of Capn4 group (not reaching the median survival time), and there were statistical differences (χ 2 = 4.351, P = 0.037). Conclusions The expression of Capn4 in breast cancer tissues is upregulated. The expression difference is correlated with TNM stage, pathological grade, ER status and the prognosis of breast cancer, suggesting that it may become a new target and molecular marker for breast cancer treatment.

Objective: To analyze the percentage of myeloperoxidase (MPO)-positive acute myeloid leukemia (AML) blast cells, and to explore the correlation of MPO expression with the clinical features, gene alterations, therapeutic response and prognosis of AML. Methods: The expressions of MPO in BM blasts cells of 233 newly diagnosed AML were retrospectived analyzed, they were divided into two groups using the percentage of MPO-positive blast [low (≤70%) and high (>70%)], clinical features, gene alterations, chemotherapy efficacy and prognosis were compared between the two groups. Results: ①Of the 233 patients, 121(51.9%) were in the low MPO group, and the rest 112(48.1%) in the high MPO group. Favorable-risk group according NCCN guidelines of AML was always MPO-high (χ(2)=32.773, P<0.001), while MPO-low was closely related to poor-risk (χ(2)=7.078, P=0.008); ②DNMT3A mutation (χ(2)=6.905, P=0.009), spliceosome genes mutation (SF3B1/SRSF2/U2AF1) (χ(2)=5.246, P=0.022), RUNX1 mutation (χ(2)=4.577, P=0.032), ASXL1 mutation (χ(2)=7.951, P=0.005) and TP53 mutation (P=0.004) were more likely to be seen in the low MPO group, while C-KIT mutation (χ(2)=8.936, P=0.003) and CEBPA mutation (χ(2)=12.340, P<0.001) were more frequent in the high MPO group, especially CEBPA double mutation; ③The rates of first complete remission in the low MPO group were significantly lower than that in the high MPO group (38.8% vs 68.1%, χ(2)=15.197, P<0.001). Multivariate analysis showed that low MPO positivity significantly affected the CR(1) unfavourably. ④The overall survival (OS) and the progression-free survival (PFS) were significantly worse in the low MPO group (18.0% vs 89.4% for OS, and 11.5% vs 56.7% for PFS, P<0.001). Multivariate analysis disclosed that the low number of MPO was significantly unfavourable prognostic factor. ⑤The low MPO group still showed a worse survival even when restricted to the patients with normal karyotype, the OS and the PFS were 31.1% and 18.8% respectively. Conclusions: AML with different MPO expression percentage had a unique gene mutation spectrum. Low expression of MPO was an independent risk factor for CR(1), OS and PFS in AML patients, which may be a simple and highly significant factor for AML patients when evaluating the therapeutic efficacy and prognosis.
