Abstract
Objective: To preliminarily investigate effectiveness and safety of sutureless integrated stented graft (SIS graft) on aortic dissection patients undergoing surgeries. Methods: In October 2019, 2 patients with aortic dissection were treated by SIS graft in Shenzhen Fuwai Hospital. Data of the operations and follow-up were recorded. Results: Patient 1 (male, 42 years old) was treated with aortic sinus repair, ascending aortic replacement, total arch replacement combined with frozen elephant trunk implantation. Time of cardiopulmonary bypass and circulatory arrest was 81 minutes and 9.5 minutes,respectively. The lowest nasopharynx temperature was 27.3 ℃. This patient was followed up for 10 months and no postoperative complication was found. Six-month postoperative aortic CT angiography (CTA) revealed SIS graft was patent and no anastomosis fistula or stent leakage occurred. True lumen of stented area was full-filled and false lumen disappeared. Incomplete false lumen thrombosis was seen in un-stented thoracic aorta, but no progressive aortic enlargement appeared. Patient 2 (male, 61 years old) was treated with ascending aortic replacement, ascending aorta to right femoral artery bypass graft, total arch replacement combined with frozen elephant trunk implantation. Time of cardiopulmonary bypass and circulatory arrest was 77 minutes and 7 minutes,respectively. The lowest nasopharynx temperature was 27.3 ℃. This patient was also followed up for 10 months and was free of postoperative complications. Six-month postoperative aortic CTA revealed SIS graft was patent and there was no anastomosis fistula or stent leakage. Perfusion of true lumen in thoracic aorta and branches of abdominal aorta improved significantly and complete false lumen thrombosis could be seen in thoracic aorta. Progressive aortic enlargement was not detected. Conclusion: Application of SIS graft can reduce circulatory arrest time and avoid deep hypothermia, which will decrease risks of postoperative complications, and this graft can simplify surgery procedure. However, further clinical trial for effectiveness and safety of SIS graft should be applied.

Abstract
Objective: The cardiopulmonary function of patients with chronic heart failure (CHF) was severely limited, but the holistic integrative exercise pathophysiology is still unclear. Methods: After signed the consent form, Eighty three patients with severe CHF from October 2016 to October 2017 in Fuwai Hospital were performed Ramp incremental loading program CardioPulmonary Exercise Testing (CPET), and 12 normal subjects served as control. CPET were performed according to standard of Harbor-UCLA MC and the circulatory, respiratory and metabolic parameters during CPET were measured and analyzed. Results: Peak oxygen uptake (Peak VO2) in CHF (14.33±2.69) ml/(min·kg), (44.25±14.74)%pred was significantly lower than control ((29.42±5.46) ml/(min·kg), (83.88±6.28)%pred). Other core parameters of CPET such as anaerobic threshold (AT), peak oxygen pulse, oxygen uptake efficiency platform (OUEP), the lowest of carbon dioxide output ventilation ratio (Lowest VE/VCO2), and carbon dioxide output ventilation slope (VE/VCO2 Slope) in CHF were significantly different with the control group(P<0.01). The core parameters of lung function, such as forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), FEV1/FVC, and carbon monoxide diffusion (DLCO) were significantly decreased (P<0.01). Systolic blood pressure during all stages of CPET in CHF was significantly lower than control group (P<0.05); Heart rate at AT, peak and recovery stages were significantly lower than control (P<0.01). Minute ventilation, tidal volume and respiratory frequency at rest, warm-up were significantly higher than control (P<0.05). Tidal volume at recovery was significantly higher than control (P<0.05). VO2 at AT, peak and recovery stages in CHF were significantly higher than control (P<0.01). Oxygen pulse at AT and peak were significantly higher than control (P<0.01). Pulse oxygen saturation during all stages of CPET in CHF were significantly lower than control (P<0.01). Conclusion: The decreased holistic functional capacity of cardiogenic CHF dominantly due to circulatory limitation, and secondly due to respiratory and metabolic limitation.

Abstract
Objective: To observe the effect of healthy volunteers different work rate increasing rate cardiopulmonary exercise testing (CPET) on the sub-peak parameters . Methods: Twelve healthy volunteers were randomly assigned to a moderate (30 W/min), a relatively low (10 W/min) and relatively high (60 W/min) three different work rate increasing rate CPET on different working days in a week. The core indicators related to CPET sub-peak exercise of 12 volunteers were compared according to standard Methods: anaerobic threshold (AT), oxygen uptake per unit power (ΔVO2/ΔWR), oxygen uptake eficiency plateau,(OUEP), the lowest average of 90 s of carbon dioxide ventilation equivalent (Lowest VE/ VCO2), the slope of carbon dioxide ventilation equivalent (VE/ VCO2 Slope) and intercept and anaerobic threshold oxygen uptake ventilation efficiency value (VO2/ VE@AT) and the anaerobic threshold carbon dioxide ventilation equivalent value (VE/ VCO2@AT). Paired t test was performed on the difference of each parameter in the three groups of different work rate increasing rate. Results: Compared with the relatively low and relatively high work rate increasing rate group, the moderate work rate increasing rate group uptake eficiency plateau, (42.22±4.76 vs 39.54±3.30 vs 39.29±4.29) and the lowest average of 90 s of carbon dioxide ventilation equivalent (24.13±2.88 vs 25.60±2.08 vs 26.06±3.05) was significantly better, and the difference was statistically significant (P<0.05); Compared with the moderate work rate increasing rate group, the oxygen uptake per unit work rate of the relatively low and relatively high work rate increasing rate group increased and decreased significantly ((8.45±0.66 vs 10.04±0.58 vs 7.16±0.60) ml/(min·kg)), difference of which was statistically significant (P<0.05); the anaerobic threshold did not change significantly ((0.87±0.19 vs 0.87±0.19 vs 0.89±0.19) L/min), the difference was not statistically significant (P>0.05). Conclusion: Relatively low and relatively high power increase rate can significantly change the CPET sub-peak sports related indicators such as the effectiveness of oxygen uptake ventilation, the effectiveness of carbon dioxide exhaust ventilation, and the oxygen uptake per unit work rate. Compared with the moderate work rate increasing rate CPET, the lower and higher work rate increasing rate significantly reduces the effectiveness of oxygen uptake ventilation and the effectiveness of carbon dioxide exhaust ventilation in healthy individuals. The standardized operation of CPET requires the selection of a work rate increasing rate suitable for the subject, so that the CPET sub-peak related indicators can best reflect the true functional state of the subject.

Abstract
BACKGROUND Until January 18, 2021, coronavirus disease-2019 (COVID-19) has infected more than 93 million individuals and has caused a certain degree of panic. Viral pneumonia caused by common viruses such as respiratory syncytial virus, rhinovirus, human metapneumovirus, human bocavirus, and parainfluenza viruses have been more common in children. However, the incidence of COVID-19 in children was significantly lower than that in adults. The purpose of this study was to describe the clinical manifestations, treatment and outcomes of COVID-19 in children compared with those of other sources of viral pneumonia diagnosed during the COVID-19 outbreak. METHODS Children with COVID-19 and viral pneumonia admitted to 20 hospitals were enrolled in this retrospective multi-center cohort study. A total of 64 children with COVID-19 were defined as the COVID-19 cohort, of which 40 children who developed pneumonia were defined as the COVID-19 pneumonia cohort. Another 284 children with pneumonia caused by other viruses were defined as the viral pneumonia cohort. The epidemiologic, clinical, and laboratory findings were compared by Kolmogorov-Smirnov test, t-test, Mann-Whitney U test and Contingency table method. Drug usage, immunotherapy, blood transfusion, and need for oxygen support were collected as the treatment indexes. Mortality, intensive care needs and symptomatic duration were collected as the outcome indicators. RESULTS Compared with the viral pneumonia cohort, children in the COVID-19 cohort were mostly exposed to family members confirmed to have COVID-19 (53/64 vs. 23/284), were of older median age (6.3 vs. 3.2 years), and had a higher proportion of ground-glass opacity (GGO) on computed tomography (18/40 vs. 0/38, P < 0.001). Children in the COVID-19 pneumonia cohort had a lower proportion of severe cases (1/40 vs. 38/284, P = 0.048), and lower cases with high fever (3/40 vs. 167/284, P < 0.001), requiring intensive care (1/40 vs. 32/284, P < 0.047) and with shorter symptomatic duration (median 5 vs. 8 d, P < 0.001). The proportion of cases with evaluated inflammatory indicators, biochemical indicators related to organ or tissue damage, D-dimer and secondary bacterial infection were lower in the COVID-19 pneumonia cohort than those in the viral pneumonia cohort (P < 0.05). No statistical differences were found in the duration of positive PCR results from pharyngeal swabs in 25 children with COVID-19 who received antiviral drugs (lopinavir-ritonavir, ribavirin, and arbidol) as compared with duration in 39 children without antiviral therapy [median 10 vs. 9 d, P = 0.885]. CONCLUSION The symptoms and severity of COVID-19 pneumonia in children were no more severe than those in children with other viral pneumonia. Lopinavir-ritonavir, ribavirin and arbidol do not shorten the duration of positive PCR results from pharyngeal swabs in children with COVID-19. During the COVID-19 outbreak, attention also must be given to children with infection by other pathogens infection.

Abstract
Objective: On the basis of preliminarily verifying the use of ultra-fast reaction polymer matrix optical fiber oxygen sensor and its measuring system to record the continuous and dynamic changes of carotid artery oxygen partial pressure (PaO2), in order to analyze and discuss the influence of lung ventilation on the continuous and dynamic changes of PaO2, we designed a whole animal experimental study in vivo. Methods: Four hybrid goats were selected, and the skin was cut and exposed directly under general anesthesia and tracheal intubation. The oxygen sensor, connected with the measuring system, was inserted directly into the left carotid artery to continuously record the dynamic changes of PaO2. With normal minute ventilation,mechanical ventilation is implemented through three tidal volumes: normal tidal volume (VT=15 ml/kg, Rf=20 bpm), half tidal volume (halved VT, doubled Rf) and double tidal volume (doubled VT, halved Rf). Each tidal volume was stable for 10~15 min respectively. We analyzed and calculated the average values of PaO2, the fluctuation magnitudes of PaO2 changes between breaths of last 180 s and the delay times of lung-carotid artery were. We analyzed the effects of different tidal volumes. Results: The heart rate and blood pressure of living goats were maintained stable during the mechanical ventilation experiment with normal ventilation volume Lung-carotid artery delay time is 1.4~1.8 s (about 3 heartbeats at this time). Under normal tidal volume of mechanical ventilation, the average value of PaO2 was (102.94±2.40, 99.38~106.16) mmHg, and the fluctuation range was (21.43±1.65, 19.21~23.59) mmHg, accounting for (20.80± 1.34, 18.65~22.22)% of the average value. Under the condition of halving tidal volume, the average value of PaO2 was maintained at (101.01±4.25, 94.09~105.66) mmHg, which was slightly decreased but not significant (P>0.05 compared with normal mechanical ventilation), but the fluctuation range of PaO2 was significantly reduced to (18.14±1.43, 16.46~20.05) mmHg, accounting for 17.5% of the average value. Under double tidal volume mechanical ventilation, although the average value of PaO2 increased slightly remained at (106.42±4.74, 101.19~114.08) mmHg (P>0.05 compared with normal mechanical ventilation and P<0.05 compared with half tidal volume mechanical ventilation), the fluctuation magnitude of PaO2 increased significantly to (26.58±1.88, 23.46~28.46)mmHg. Conclusion: Inspiration and expiration of normal lung ventilation are the initial factors for the increase and decrease of PaO2 in carotid artery. Under normal ventilation, halving tidal volume and doubling tidal volume significantly changed the fluctuation magnitude of PaO2, but the average value of PaO2 changed only slightly, while the lung-carotid delay time was similar.

Abstract
Objective: We tried to implant the ultra-fast polymer optical fiber chemical oxygen sensor (POFCOS) into arterial blood vessel,connect with photoelectric conversion measurement system to record the continuous dynamic rapid changes of arterial PO2(PaO2) in whole living animals. It should be the experimental evidence for the new theory of holistic integrative physiology and medicine(HIPM) forexplain the mechanism of respiratory control and regulation in whole circusof respiration-circulation-metabolism. Methods: ①Fabrication of ultrafast POFCOS, calibration and its measuring system: The distal part of 2 m optical fiber was heated and pulled until it became a tapered tip. After cleaning and drying, the tip of 1 mm tapered optical fiber was dip-coated into the luminophore doped polymer solution, then was slowly pumped out while solvent was quickly evaporated to form an oxygen sensing tip, which was dried at room temperature for 24 hours. ②Animal experiments: Under general anesthesia and intubation, goatwas mechanically ventilated with 40%~60% oxygen. We exposed both right and left carotid arteries and the left femoral artery by skin cutting, and inserted the POFCOS directly into the arteries via indwelling catheter. The end of POFCOS were connected to the personal computer through optical fiber, excitation and detection Y-type optical fiber coupler through photoelectric conversion, so as we can realize the continuous dynamic response of living goat carotid PaO2 under mechanical ventilation. We mainly analyzed the intra-breath wave-form alternate increase and decrease of PaO2 and their time delay between lung and carotid arteries.We completes breathing control whole loop to explain the mechanism of mutual breathing and the switching of inspiration and exhalation. Results: The POFCOS has a very fast T90 response time was set 100 ms for liquid. When the heart rate of 40%~60% oxygen mechanical ventilated living goat was ~110 bpm, the PaO2 of left and right carotid artery showed a same wave-sizeup and down following with the inspiration and expiration of ventilator, with a range of up to 15 mmHg. There weresignificant noises of PaO2 change recorded in the left femoral artery. The lung-carotid artery time delay is 1.5~1.7 s after inhalation and exhalation, PaO2 at both left and right carotid arteries starts toincrease and decrease. After two-three heartbeats after the start of lung ventilation, thealternate up-down wave-form information of the arterialized pulmonary vein blood after pulmonary capillaries waspumpedby left ventricle to the position of peripheral chemoreceptors,thus realizing the whole cycle of inhalation and exhalation. It alternately interrupted inhalation, i.e. switching inhalation to exhalation, and then interrupted exhalation,i.e. switching exhalation to inhalation. Conclusion: The ultra-fast reactive implantableoxygen sensor and its measuring system can measure the physiological waveform changes of PaO2 in living animals, which can provide experimental evidence for explaining the mechanism of switching of inspiration-expiration in HIPM.

Abstract
Objective: The objective is to find the characteristics of arterial blood sample waveform in different respiration models. Methods: Six post-operative patients with normal heart function and negative Allen test, were 4 male and 2 female, (59.00±16.64)year, (71.67±0.37)kg, left ventricular ejection fraction(LVEF) (61.33±2.16)%, had been placed the arterial catheterization and central venous catheterization for continuous collecting arterial in 3 different kinds of respiration models: normal breathing, no breathing and deep breathing. We selected two breaths cycles of waveform from each patient for data calculations of magnitudes and time interval. Compare the adjacent highest and lowest values of patients to verify whether there are periodic wave-like signal changes in arterial and venous blood gas in the three breathing states. In addition, statistical t-test analysis was performed on the change amplitude of the periodic wave-like signal of the patient's arterial and venous blood gas to compare whether there is a difference. Results: The heart beat numbers for drawing blood into pipe were 15-16, and all covered more than 2 breathing cycles. There were significant changes of arterial PaO2 (i.e. the highest high values compare to the next lowest values, P<0.05) in three different breathing models(normal, no breathing and high breathing), the magnitudes of which were (9.96±5.18)mmHg, (5.33±1.55)mmHg and (13.13±7.55)mmHg, with (8.09±2.43)%, (5.29±2.19)% and (10.40±2.68)% from their mean respectively. PO2 in venous blood gas did not show wavy changes under normal breathing, 20 s breath holding and high tidal volume ventilation. The amplitudes were (1.63 ± 0.41) mmHg, (1.13 ± 0.41) mmHg and (1.31 ± 0.67) mmHg, which were (3.91 ± 1.22)%, (2.92 ± 1.12)%, (3.33 ± 1.81)%, respectively, which were significantly lower than that of arterial blood gas under the same state, but there was no significant difference between groups. Conclusion: With continuous beat-by-beat arterial blood sampling and ABG analyzing method in three different breathing models, We obtain a clear evidence of the biggest periodic parameters ABG waveform in high breathing models, which followed by normal breathing models, no breathing was the smallest, and the wave variation amplitude of venous oxygen partial pressure was not obvious in the three respiratory states, which implies the oscillatory information of the arterial blood with comes from the gas exchanging in the lung.

Abstract
AIM The study aim was to analyse the safety and feasibility of laparoscopic intersphincteric resection with stapled coloanal anastomosis for low rectal cancer. METHOD Between March 2009 and August 2010, 22 patients underwent laparoscopic intersphincteric resection with a stapled coloanal anastomosis without a diverting ileostomy. The results were compared retrospectively with hand-sewn coloanal anastomoses performed between January 2001 and May 2009, which included 55 open and 38 laparoscopic intersphincteric resections. The morbidity comparison only included data relevant to the anastomosis. Function was compared using the Saito function questionnaire and the Wexner score and only involved data relevant to the laparoscopy. RESULTS The anastomotic complication rates were similar for fistula, bleeding and neorectal mucosal prolapse (P = 0.526, P = 0.653 and P = 0.411, respectively). Anastomotic leakage and stricture formation of the stapled coloanal anastomosis were significantly lower than those of the hand-sewn coloanal anastomosis (P = 0.037 and P = 0.028, respectively). There were no significant differences in the Saito function questionnaire and the Wexner score between the stapled and hand-sewn coloanal anastomotic groups (all P > 0.05). CONCLUSION Laparoscopic intersphincteric resection with a stapled coloanal anastomosis is technically feasible and is less likely to result in anastomotic leakage and stricture formation than a hand-sewn anastomosis.

Abstract
BACKGROUND Human arrest defective 1 protein (ARD1), as a N-terminal acetyltransferase, has been reported to play a crucial role in tumorigenesis, but the results are somewhat controversial. To explore the clinical and pathological significance of ARD1 in breast tumorigenesis, we analyzed ARD1 status in multiple types of breast disease. METHODS The expression of ARD1 protein was assessed by immunohistochemistry in 356 cases including 82 invasive ductal carcinomas (IDC), 159 fibroadenomas, 66 hyperplasia of mammary glands, 19 inflammatory breast disease, 30 breast cysts, and in 29 postoperative treatment patients. We assessed the relationship of ARD1 protein with clinical and pathological characteristics using χ2 test. RESULTS ARD1 protein was observed at 61.0% (50/82), 54.7% (87/159), 37.9% (25/66), 36.8% (7/19) in IDC, fibroadenoma, hyperplasia, and inflammation, respectively, and less than 30.0% for breast cyst. Thus, high ARD1 expression correlated with breast cancer (relative risk = 1.32, P < 0.005). Moreover, the level of ARD1 protein in carcinoma patients was distinctly related to lymph node metastasis and ER status, with 94.0% (47/50) as copmpared to 6.0% (3/50) in metastatic and non-metastatic (P < 0.001), and 84.0% (42/50) and 16.0% (8/50) for ER + and ER - (P < 0.01), respectively. In addition, the level of ARD1 appeared to have potential for evaluation of prognosis in breast cancer patients after postoperative therapy. CONCLUSIONS These results suggest that ARD1 expression may be as a potential target for exploring the mechanism of breast cancer metastasic to lymph nodes and hormone-responsive regulation.

Abstract
OBJECTIVE To investigate the specific anti-breast cancer immune response induced by dendritic cells (DC) loaded with trastuzumab and apoptotic Her-2+ breast cancer cells. METHODS DCs were generated from healthy peripheral blood mononuclear cells (PBMCs) in the presence of recombinant cytokines GM-CSF, IL-4 and TNF-alpha. Mature DCs were harvested after 7 days' co-culture of PBMCs and trastuzumab-treated apoptotic SKBr3 cells. The morphologic characteristics and ultrastructure of the DC were observed under the inverted phase-contrast microscope and transmission electron microscope (TEM), respectively. Flow cytometry (FCM) was used to check the expression of several DC specific markers: CD14, CD1a, CD64, CD80, CD83, CD86, HLA-ABC and HLA-DR. DC-cytokine induced killer (DC-CIK) cells were prepared by co-culture of DCs and peripheral blood lymphocytes in the presence of anti-CD3 antibodies and human IL-2 at an appropriate concentration. The number of antigen-specific T cells was analyzed by human interferon gamma enzyme linked immunospot (ELISPOT) assay. MTT assay was employed to assess the lysis of breast cancer cell line induced by DC-CIK cells. RESULTS 5 minutes after the adding of DCs to SKBr3 cells pretreated with trastuzumab, the apoptotic SKBr3 cells were found to be circled by DCs. 48 hours later, many membrane-wrapped organelles of the apoptotic target cells in the cytoplasm of DCs were found by TEM. The majority of the organelles were degraded. Fewer organelles from the apoptotic cells were found in DCs without Herceptin. More than 60% in every group of DCs expressed a high-affinity receptor for IgG (FcgammaRI or CD64). CD14 expression on the mature DCs were comparatively lower, and HLA-DR and HLA-ABC expressions were higher in the trastuzumab group. The expression of CD1a, CD80, CD83 and CD86 in trastuzumab group were higher than those in immature DCs group (P < 0.05). ELISPOT assay suggests that the spot number of antigen-specific T cells were higher in trastuzumab group than that in the antigen unloaded DCs group (P < 0.05). The lysis of SKBr3 cells induced by the SKBr3 antigen loaded DC-CIK cells were 1.7 times higher than that of CIK. CONCLUSION The lysis of SKBr3 cells induced by DC-CIK was increased after that DCs were combined with trastuzumab to capture antigen from SKBr3 cells. These findings support further investigation into the use of combination immunotherapy of the humanized monoclonal antibody, DC vaccines and immunological effector cells.

Abstract
UNLABELLED Effects of morphine on acquisition and retrieval of memory have been proven in the avoidance paradigms. In present study, we used a two-trial recognition Y-maze to test the effects of acute morphine and morphine withdrawal on spatial recognition memory. The Y-maze is based on the innate tendency of rodents to explore novel environments and therefore avoid punishment and reward. RESULTS 1) Pre-training morphine 10 mg/kg impaired the recognition spatial memory of acquisition after a 1 h inter-trial interval (ITI), whereas morphine 2.5, 5 and 10 mg/kg showed impairment after 2 h ITI. 2) Pre-retention morphine 5, 10 mg/kg disrupted the retrieval of memory after 1 h ITI. 3) Morphine 5 and 10 mg/kg caused hyper-locomotor activity depending on the state. 4) Mice withdrawn from morphine 40 mg/kg but not 10 mg/kg for 3 days showed amnesia in Y-maze. Our data suggested that acute morphine impaired the acquisition and retrieval of spatial recognition memory and increased the locomotor activity in the Y-maze depending on the dose and state. Moreover, withdrawal from chronic morphine also impaired acquisition in the Y-maze depending on the dose and state.

Abstract
In order to investigate whether cytokine-induced killer (CIK) cells can induce apoptosis of bcr-abl(+) K562 cells, apoptosis of K562 cells and CEM cells induced by CIK cells, etoposide or camptothecin was detected with flow cytometry DNA assay. RT-PCR showed that K562 cells expressed the bcr-abl fusion gene, K 562 cells, K562 cells/etoposide or K562 cells/camptothecin groups showed no sub-G(1) peak. K562 cells/CIK cells group showed sub-G(1) peak (38.1%). CEM cells showed no sub-G(1) peak. CEM cells/camptothecin or CEM cells/etoposide groups showed sub-G(1) peak (23.5% or 32.3% respectively). CEM cells/CIK cells group showed sub-G(1) peak (45.4%). Etoposide or camptothecin did not induce apoptosis of K562 cells. CIK cells induce apoptosis of K562 cells. Bcr-abl fusion gene prevented apoptosis induced by etoposide or camptothecin, but did not prevent apoptosis induced by CIK cells. This property may support the observed adoptive immunologic effect of allogeneic bone marrow transplantation and donor lymphocyte transfusions of CML case relapsing after allogeneic bone marrow transplantation.

Abstract
Ten patients with multiple myeloma (two refractory and eight relapsing) received vincristine and adriamycin infusion therapy with oral high-dose dexamethasone (VAD regimen). Reduction in monoclonal immunoglobulin in serum exceeding 75 per cent was noted in three patients and reduction from 50 per cent to 75 per cent in four patients. Total response rate was 70 per cent. It was as high as the results reported in other countries. The responses to VAD regimen occurred rapidly. Most of them needed only one course. The side effects of VAD were not severe and were mainly reversible depression of leukocyte and infection of various kinds. All patients tolerated well. The probable mechanisms for increased response to VAD regimen are as follows. 1. Instead of administration as a bolus, vincristine and adriamycin were infused continuously and were given several times; therefore there was a prolonged unchanged concentration of the drugs in blood and exerting a possibly superior antitumor effect. 2. high-dose dexamethasone.

Abstract
36 cases of coexistent hyperthyroidism and idiopathic thrombocytopenic purpura (ITP) were reported. There were 33 cases of overt hyperthyroidism with ITP. After treatment with antithyroid drugs the platelet count returned to normal in 29 and somewhat increased in the remaining four cases. The other three cases had ITP accompanied by hyperthyroidism. In 2 cases the platelet count decreased when they had accompanying hyperthyroidism. When the thyroid function returned to normal after antithyroid treatment, the platelet count returned to normal in one and increased in another. The authors discussed the association between hyperthyroidism and ITP and treatment of coexistent hyperthyroidism and ITP. Probable mechanisms causing thrombocytopenia in hyperthyroidism were discussed also.
