ABSTRACT
Objective:To explore risk factors for relapse after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in adult Philadelphia chromosome-negative B-cell acute lymphoblastic leukemia (Ph-ALL).Methods:A retrospective analysis was performed for 65 adult Ph-ALL patients undergoing initial allo-HSCT from 2016 to 2018. The effect of baseline level and treatment pre-transplantation for relapse after allo-HSCT was analyzed.Results:There were 37 males and 28 females with a median age of 25(14-58) years during allo-HSCT. And the median follow-up period was 27 months post-HSCT. The 2-year overall survival (OS) was 78.8%(95%CI 67.8%-89.8%) and the 2-year relapse-free survival (RFS) 70.7% (95%CI 58.2%-83.2%). Pre-transplant chemotherapy was offered for 3 to 7 courses and the median dose of polyethylene glycol-conjugated asparaginase (PEG-ASP) was 3 doses (2 000 IU/m 2 per dose). Multiariate analysis revealed that the regimen included more than 4 doses of PEG-ASP pre-HSCT (HR=4.067, P=0.046) was a protective factor for post-transplant relapse (HR=0.193, P=0.009). High-risk chromosome karyotype was a risk factor for relapse (HR=0.193, P=0.009). The 2-year RFS rate was 90.0%(95%CI 79.2%-100.0%) for intensive PEG-ASP group and 56.9%(95%CI 39.1%-74.7%) for control group ( P=0.01). No significant inter-group difference existed in overall survival (OS)( P=0.079). The 2-year OS was 90.6% (95%CI 80.4%-100.0%) in intensive PEG-ASP group and 72.1% (95%CI 56.6%-87.6%) in control group. Conclusions:For adult ph-ALL patients, a higher dose of PEG-ASP in pretransplant chemotherapy regimens may improve post-transplant RFS and achieve a better outcome.
ABSTRACT
In Taiwan, high-risk patients have been identified and tested for preventing community spread of COVID-19. Most sample collection was performed in emergency departments (EDs). Traditional sample collection requires substantial personal protective equipment (PPE), healthcare professionals, sanitation workers, and isolation space. To solve this problem, we established a multifunctional sample collection station (MSCS) for COVID-19 testing in front of our ED. The station is composed of a thick and clear acrylic board (2 cm), which completely separates the patient and medical personnel. Three pairs of gloves (length, 45 cm) are attached and fixed on the outside wall of the MSCS. The gloves are used to conduct sampling of throat/nasal swabs, sputum, and blood from patients. The gap between the board and the building is only 0.2 cm (sealed with silicone sealant). ED personnel communicate with patients using a small two-way broadcast system. Medical waste is put in specific trashcans installed in the table outside the MSCS. With full physical protection, the personnel conducting the sampling procedure need to wear only their N95 mask and gloves. After we activated the station, our PPE, sampling time, and sanitization resources were considerably conserved during the 4-week observation period. The MSCS obviously saved time and PPE. It elevated the efficiency and capacity of the ED for handling potential community infections of COVID-19.

ABSTRACT
Objective To investigate the effect of the interaction between satellite glial cells and neurons in the trigeminal ganglion of trigeminal neuralgia (TN) rat model. Methods In the TN rat model (n = 24) induced by trigeminal root entry zone chronic compression and sham group (n = 24), immunofluorescence and Western blotting were used to detect the expression of myelin basic protein (MBP), glial fibrillary acidic protein (GFAP) and of P75 neurotrophic factor receptor (P75) in the trigeminal ganglion. Results The expression of P75NTR in TN group was higher than that in the sham operation group, especially on the post-operation day (POD) 7 and 14 (P<0.01). The expression of MBP in the TN group was decreased after operation, which were significant lower than that in the sham operation group on POD 7 and 14 (P<0.05). While the expression of immunoreactive GFAP in the satellite glial cells in the TN group was higher than that in the sham operation group from POD 7 to POD 21 after operation (P<0.01). Conclusion The changes of MBP and P75NTR expression in neurons and the activation of satellite glial cells in trigeminal ganglion of the TN animal model may affect the interaction of neuron-satellite glial cells, which may be involved in the nociceptive information transmission from orofacial area to the central nervous system in the TN rats.
ABSTRACT
This study aimed to observe the general state and changes in pathophysiological indexes of multiple cerebral infarction rat model with Qi-deficienty and Blood-stasis syndrome. Rats were randomly divided into 4 groups(with 30 in each group): the normal group, the sham group, the model group and the Yiqi Huoxue recipe group. Rats in the model group and Yiqi Huoxue group were provided with interruptable sleep deprivation for 7 days before the multiple cerebral infarction operation, and followed by another 4 weeks of sleep deprivation; rats in the Yiqi Huoxue group were intragastrically administrated with drug at a dose of 26 g·kg⁻¹, once a day for 4 weeks. The general state was observed, and the pathophysiological indexes were measured at 48 h, 2 weeks and 4 weeks after administration. The results showed that rats in the normal group and the sham group represented a good general state and behaviors, with a normal morphological structure of brain tissues; rats in the model group featured yellow fur, depression, accidie, loose stools and movement disorder, with obvious brain histomorphological damage, which became aggravated with the increase of modeling time; rats in the Yiqi Huoxue group showed release in the general state and above indexes. Compared with the sham group at three time points, rats in the model group showed decrease in body weight, exhaustive swimming time and RGB value of tongue surface image, and increase in whole blood viscosity of the shear rate under 5, 60 and 150 S⁻¹, reduction in cerebral cortex Na⁺-K⁺-ATPase, Ca²⁺-ATPase activity and contents of 5-HT, rise in TXB2 levels and decline in 6-keto-PGF1a in serum(<0.05, <0.01). Compared with the model group, rats in the Yiqi Huoxue group showed alleviations in the above indexes at 2 w and 4 w(<0.05, <0.01). The results showed that the characterization and pathophysiological indexes in the multiple cerebral infarction rat model with Qi-deficiency and blood-stasis syndrome were deteriorated; Yiqi Huoxue recipe could significantly alliviate the abnormal conditions, which suggested of the model was stable and reliable and the pathophysiologic evolutionary mechanism might be related to energy metabolism dysfunction, vasoactive substance abnormality and changes in neurotransmitters.

The comparison on evaluating blood stasis syndrome in sleep deprived rats was carried out by using R, G, B image analysis of Tongue and palm as well as auricle, palm surface laser Doppler flow perfusion. The experiment was performed by means of a small platform on the water environment for sleep deprivation. The rats were weekly weighed at fixed time, and their macroscopic signs were observed; and their tongue and palm images of the control and model group were respectively collected by the SLR camera at the 2nd, 4th and 6th week. Then the color saturation analysis was performed by means of proofreading with the standard colorimetric card. At the same time, the laser dopper flowmetry was used to analyze the perfusion of auricle and foot flow in rats. It turned out that there was no significant difference in the R,G,B value of the tongue and palm in rats between normal group and model group at the first stage(at the 2nd week), so were the perfusion of auricle and foot flow in rats. But at the second stage (at the 4th week), the R value of tongue in model group rats was obviously lower than that in normal group(<0.01), and the other value (G,B) of tongue in module rats had a decease tendency, but there was no statistical significance. However, the perfusion of left and right auricle flow in model group rats were dramatically decreased as compared with the normal group(<0.01); there was still no significant difference in the perfusion of the palm between two groups. It was found that R,G,B value in model group had a lower trend as compared with the control group of the tongue and palm images at the third stage (at the 6th week), but no statistically significant difference. The perfusion of left and right auricle flow in model group was constantly decreased as compared with the normal group(<0.01).Right and left foot blood flow was lower than the normal group, but no statistically significant difference. We can safely conclude that the results of the R, G, B values of the tongue in rats could objectively reflect the characteristics of the rats with blood stasis syndrome, which were consistent with the diagnosis of clinical tongue image. As a method of microcirculation evaluation, the surface laser doppler perfusion of auricle can exhibit the characteristics of blood stasis in model rats, but also was more objective and reproducible. Therefore, the combination of R, G, B value of tongue as well as auricle laser doppler blood flow is more beneficial to the objective evaluation of index in the later study of traditional Chinese medicine blood stasis syndrome model.
ABSTRACT
Based on the theory of "overexertion leading to Qi consumption", this study aimed to compare the intervention factors of nervous and physical fatigue to establish a rat model of Qi deficiency syndrome, moreover, the systematic evaluationsystem was necessary with the standard of syndrome diagnosis of Qi deficiency. According to the clinical-mimetic principle the Qi deficiency syndrome animal model is established by the factors of sleep deprivation(SD) and exhaustive swimming(ES). Rats were randomly divided into four groups, normal group, SD group, ES group and compound group (exhaustion swimming complex sleep deprivation). The method of ES was force rats to swim until the exhaustion with 5% of weight, and the SD method by using multi-platform sleep deprivation of water environment randomly 14-16 h daily, and the complex set by using of two methods was combined. The movement distance, average speed, activity time and numbers into the central area were detected by open field test, swimming exhaustion time was detected by swimming exhaustion method, the cardiac function (LVEF, CO, FS, LVDd) was detected by echocardiography, tongue imaging analysis and pulsedistention as the index of tongue and pulse diagnosis, the content of ATP and ADP in serum was detected by ELISA, the blood coagulation indexes for blood stasis syndrome as the additional. These results indicated that independent activity, body weight and exercise capacity were decreased significantly, the neurological function injured significantly, heart function was decreased significantly, the tongue surface color was pale white, and the pulse distention was decreased significantly. The content of ATP decreased significantly and the ADP increased significantly. By the method of four-diagnostic evaluation system to compare the factors of SD and ES, the Qi deficiency syndrome animalmodel could be successfully established by sleep deprivation method.

ABSTRACT
Chinese medicine Buyang Huanwu decoction (BYHW) is widely used in treating cerebral infarction combined with Qi-deficiency and blood-stasis syndrome, but the pharmacological basis is still not clear. This study aims to uncover the biological basis of BYHW therapy for cerebral infarction combined with Qi-deficiency and blood-stasis syndrome using label-free proteomic technology. Using Qi deficiency and blood stasis rat cerebral infarction model as the research object, the protein expression of rat brain tissue was compared among the sham operation group, the model group and the drug group. Quantitative analysis of the 3 groups of tissue samples detected 3 959, 3 996 and 4 055 proteins in the sham operation group, the model group and the drug group, respectively. Take model group as the control group, 391 proteins were identified to be upregulated or downregulated for more than 2 folds. Biological analysis and functional enrichment of the differentially expressed proteins revealed that BYHW may treat cerebral infarction combined with Qi-deficiency and blood-stasis syndrome through energy metabolism, nervous system and several signal pathways. This study preliminarily revealed the pharmacological mechanism of BYHW at the protein level, and provided a molecular basis for clinical treatment and traditional Chinese medicine research on cerebral infarction combined with Qi-deficiency and blood-stasis syndrome.
ABSTRACT
Blood stasis syndrome is the pre-state of thrombotic disease. The model of blood stasis syndrome in rats was induced by sleep deprivation to study on effects of blood stasis syndrome on platelet activation. The weight, the color of tongue and hemorheology for the blood stasis syndrome of Chinese medicine were measured after modeling. The release of platelet granules and platelet activation factors in plasma were detected by ELISA kit related indicators to provide experimental basis for platelet function evaluation and related drug effects in syndrome research. The results showed that the weight of the model group rats was significantly lower than that of the normal group (<0.01). The tongue showed a dark purple blood stasis pattern, and the R, G and B values of the tongue surface in model group were significantly lower than those of the normal group (<0.01). The hemorheological parameters including high shear, middle shear and low shear viscosity in whole blood were significantly higher than those in the normal group (<0.01). But plasma viscosity did not change significantly. The release levels of platelet α particles (GMP-140, -TG, PF4) and dense particles (ADP, 5-HT) were significantly higher than those in the normal group (<0.01). The levels of TXB₂ and 6-keto-PGF₁α in plasma were significantly higher than those in the normal group (<0.01). The ratios of TXB₂ and 6-keto-PGF₂α were also significantly higher than those in the normal group (<0.01). The levels of PAF in plasma in model group were significantly higher than those in the normal group (<0.01). It was concluded that platelet functions could be changed induced by sleep deprivationin rats with blood stasis syndrome, and there might be inflammation and endothelial cell dysfunction.

ABSTRACT
This study was designed to investigate the effect of Yinxing Mihuan oral solution on rats with myocardial ischemia injury. Left anterior descending (LAD) coronary artery was occluded in rats to establish the model. Yinxing Mihuan oral solution was given by intragastric administration daily for one week at dosage of 309 and 618 mg·kg-1. Cardiac ultrasound function, pathologic change and serum myocardial enzymes were determined to evaluate the effect of Yinxing Mihuan oral solution. The heart function was significantly reduced in the model group compared with sham operation group, and the pathologic damage was clear. The changes were significantly improved by Diltiazem hydrochloride tablets in heart function and ejection fraction (P -1) (P P < 0.01). In addition, Yinxing Mihuan oral solution decreased the myocardial damage and inhibited inflammatory reaction, and inhibited platelet activation factor. Yinxing Mihuan oral solution can protect against myocardial ischemia injury, inflammation and platelet activation in the rat model.
ABSTRACT
This study was conducted to investigate the effects of Danlou (correspondence between prescription and syndrome) tablet and Shengmai capsule (non-correspondence between prescription and syndrome) on mini-swine phlegm-stasis syndrome of coronary heart disease (CHD). 24 mini-swines were randomly divided into normal control group, model group, Danlou tablet group (0.24 g·kg-1) and Shengmai capsule group (0.14 g·kg-1). Phlegm-stasis syndrome of coronary heart disease was established by high-fat feeding and coronary intervention balloon injury. After 8 weeks of administration, blood lipid levels and blood rheology was detected. Echocardiography was used to examine the changes in heart function, and the extent of infarction was determined by nitro blue tetrazolium (NBT) staining method. The main symptoms, accompanied symptoms, tongue and pulse signs of the coronary heart disease mini-swine with phlegm-stasis syndrome were observed according to the symptom-graded scoring method. The results showed that Danlou tablet decreased serum total cholesterol (TC), triglyceride (TG) and low-density lipoprotein cholesterol (LDL-C) (P P P P P P P P P P P P < 0.05). However, Shengmai capsule failed to show therapeutic effects on blood lipid metabolism, the myocardial infarction area and primary symptom and syndrome score. The results suggest that as a drug for the treatment of Qi and Yin deficiency syndrome of CHD, Danlou tablet has limited therapeutic effects on phlegm-stasis syndrome of CHD. Only by the prescription correspondence with syndrome, using drug for the treatment of phlegm-stasis syndrome of CHD to treat phlegm-stasis syndrome of CHD, the prescription has a comprehensive therapeutic effect.
ABSTRACT
Tianlongtongxin (TLTX) formula is composed of six Chinese herbs including Rhodiola rosea L., Salviae Miltiorrhizae Radix et Rhizoma, Chuanxiong Rhizoma and so on. It has been mainly used in the treatment of chest-Bi syndrome in the clinics. To investigate the material foundation and provide reference for clinical dosage regimen, the pharmacokinetics of seven components in the rat plasma were studied after oral administration of TLTX. A high sensitive method was established to determine the seven active components from TLTX in rat plasma based on the LC-MS/MS technique. The method met the requirements of preclinical pharmacokinetic study, through the investigation of linearity, specificity, recovery, accuracy, precision and stability. After administration of TLTX at 4.5 g·kg-1 dose, all of the components were detectable in the plasma after 5 min. The concentration peaks were observed at 0.11-4.67 h respectively after administration with great difference in levels. The AUC of salidroside was significantly higher than other components, suggesting it as a main active component in TLTX formula. The observations provide scientific evidence for the rationality of salidroside as monarch drug in the formula.
