ABSTRACT

During fluorescence-guided cancer surgery, ultra-pH sensitive (UPS) fluorescent nanoprobes has multiple advantages such as real-time imaging procedures, ultra-high imaging sensitivity as well as broad tumor detection specificity. UPS nanoprobes stay at "OFF" state at higher pH and turn into "ON" state at lower pH with emission of strong fluorescence. Moreover, the transition pH points (transition pH point, pHt) can be precisely controlled by structural-based strategy. One of the previously-reported UPS nanoprobes showed good imaging effect. However, it is still not clear about the effect of pHt on cancer imaging efficiency of UPS nanoprobes and to further identify the optimal UPS. In this study, we synthesized a series of UPS nanoprobes with pHt at 4.5, 6.2, 6.6, 7.8 by adjusting the hydrophobic blocks of UPS polymers. Each nanoprobe showed excellent stability in "OFF" state by dynamic light scattering and uniform morphology observed by transmission electron microscopy. In vitro imaging characterized the ultra-pH sensitive fluorescence transition of each probe. In vivo imaging results identified two UPS nanoprobes (NP-6.2 and NP-6.6) with superior tumor imaging effect. All animal experiments in this study were approved by the Animal Ethics Committee of Peking University Health Science Center and were strictly followed by the welfare regulations of laboratory animals of Peking University Health Science Center. Therefore, this study has explored the effect of pHt on the cancer imaging efficiency of UPS nanoprobes and provides a new idea for design of the other cancer microenvironment-responsive polymers.

ABSTRACT

Graft-versus-host disease (GVHD) is the most common complication after allogeneic hematopoietic stem cell transplantation, and also an important factor affecting the survival and quality of life in patients after transplantation. Currently, immunosuppressive therapy is commonly used for GVHD, but the curative effect is not ideal. How to effectively prevent and treat GVHD is one of the difficulties to be solved urgently in the field of transplantation. In this paper, we summarize the latest progress in pathogenesis, prevention and treatment of GVHD with Chinese medicine (CM). We hope it will provide ideas and methods for exploring the mechanism and establishing a new comprehensive therapy for GVHD with CM.

ABSTRACT

Objective: T-cell immunoglobulin and mucin-domain containing-3 (Tim-3) has been widely recognized as a negative regulator of antitumor immunity. However, the mechanism by which Tim-3 suppresses antitumor treatment in gliomas remains unclear. This study aims to explore whether Tim-3 is expressed and to evaluate its effect in drug-fasted glioma cells. Subjects and Methods: U87 and U251 glioma cell lines were tested. Cell proliferation activity, cell viability, and the protein and mRNA levels of Tim-3 were detected using CCK-8, flow cytometry, Western blotting, and reverse transcription-quantitative polymerase chain reaction, respectively. Enhancement of the sensitivity of glioma cells to chemotherapeutic agents was tested after inhibiting Tim-3 expression using Tim-3 small interfering RNAs (siRNA). Results: As temozolomide (TMZ) concentration increased, the ratio of apoptotic cells also increased accordingly. However, the level of Tim-3 expression in living cells from the high-dose group was higher than in the low- and middle-dose groups. After interfering with the expression of Tim-3 using siRNA against Tim-3, the killing effect of TMZ rose through an increase in apoptosis. Conclusions: The presence of Tim-3 mRNA and protein in glioma cells was detected. Significantly, knocking down Tim-3 expression improved the potential of TMZ treatment.

ABSTRACT

OBJECTIVE@#To investigate the potential efficacy of panaxadiol saponins component (PDS-C) in the treatment of aplastic anemia (AA) model mice.@*METHODS@#Totally 70 mice were divided into 7 groups as follows: normal, model, low-, medium-, high-dose PDS-C (20, 40, 80 mg/kg, namely L-, M-, H-PDS-C), cyclosporine (40 mg/kg), and andriol (25 mg/kg) groups, respectively. An immune-mediated AA mouse model was established in BALB/c mice by exposing to 5.0 Gy total body irradiation at 1.0 Gy/min, and injecting with lymphocytes from DBA mice. On day 4 after establishment of AA model, all drugs were intragastrically administered daily for 15 days, respectively, while the mice in the normal and model groups were administered with saline solution. After treatment, the peripheral blood counts, bone marrow pathological examination, colony forming assay of bone marrow culture, T lymphocyte subpopulation analysis, as well as T-bet, GATA-3 and FoxP3 proteins were detected by flow cytometry and Western blot.@*RESULTS@#The peripheral blood of white blood cell (WBC), platelet, neutrophil counts and hemoglobin (Hb) concentration were significantly decreased in the model group compared with the normal group (all P<0.01). In response to 3 dose PDS-C treatment, the WBC, platelet, neutrophil counts were significantly increased at a dose-dependent manner compared with the model group (all P<0.01). The myelosuppression status of AA was significantly reduced in M-, H-PDS-C groups, and hematopoietic cell quantity of bone marrow was more abundant than the model group. The colony numbers of myeloid, erythroid and megakaryocytic progenitor cells in the model group were less than those of the normal mice in bone marrow culture, while, PDS-C therapy enhanced proliferation of hematopoietic progenitor cells by significantly increasing colony numbers (all P<0.01). Furthermore, PDS-C therapy increased peripheral blood CD3 and CD3CD4 cells and reduced CD3CD8 cells (P<0.05 or P<0.01). Meanwhile, PDS-C treatment at medium- and high doses groups also increased CD4CD25FoxP3 cells, downregulated T-bet protein expression, and upregulated GATA-3 and FoxP3 protein expressions in spleen cells (P<0.05).@*CONCLUSION@#PDS-C possesses dual activities, promoting proliferation hematopoietic progenitor cells and modulating T lymphocyte immune functions in the treatment of AA model mice.

ABSTRACT

Objective · To observe the vascular structure before autogenous arteriovenous fistula (AVF) construction in patients with end-stage renal disease (ESRD) and analyze the risk factors of the pre-existing venous neointimal hyperplasia. Methods · The 8 vein samples were screened from 20 ESRD patients at their first time of the AVF construction (non-stenosis group), and the other 8 vein samples were screened from 15 ESRD patients at their at least second time of the AVF repair operation (stenosis group). Sections were prepared and stained with hematoxylin & eosin (H-E) or Masson's trichrome for observation. The intimal thickness was measured by the cellSens software, and its correlation with patients' renal function, calcium-phosphorus metabolism, iron metabolism and inflammatory reaction in the non-stenosis group were analyzed. Results · In the non-stenosis group, there were varying degrees of intimal hyperplasia in 5 (62.5%) cases, loss of endothelial cell layer in 3 (37.5%) cases, and vascular wall replacement by collagenous with atrophy or loss of muscle layer in 5 (62.5%) cases. In the stenosis group, almost all vein samples showed general thickening of the wall and 2 (25.0%) totally lost the muscle layer. Avg It of those two groups were statistically significant (P<0.01). In the non-stenosis group, both of average I/M thickness and average I/M area were negatively related to glomerular filtration rate (GFR) (P<0.05) and positively related to serum phosphorus and calcium-phosphorus product (P<0.05). Conclusion · Some apparently normal vein of ESRD patients showed varying degrees of intimal hyperplasia before AVF construction. The intimal hyperplasia had a remarkable correlation with GFR or calcium-phosphorus metabolism. Early intervention of the intimal hyperplasia prior to AVF construction may be a new prevention and control means.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the surgical options and clinical effects of delayed osteoporotic vertebral collapse.</p><p><b>METHODS</b>From May 2010 to October 2014, 19 patients (20 vertebrae) with delayed osteoporotic vertebral collapse(Kümmell's disease) were enrolled in this study. There were 7 males and 12 females, aged from 65 to 87 years old with a mean of (73.5±5.62) years. According to Li staging system of Kümmell's disease, 3 cases were stage II, 13 cases (14 vertebrae) were stage III without spinal cord injury, 3 cases were stage III with spinal cord injury. Patients were respectively treated with percutaneous vertebroplasty(PVP) or percutaneous kyphoplasty(PKP) on the basis of the degree of postural reduction during operation. Injected cement volume, cement leakage, vertebral height restoration and local kyphotic reduction were observed. Visual analogue scale (VAS) and Oswestry Disability Index(ODI) were respectively used to assess the pain and function before and after operation. Frankel grade were used to evaluate neurological status.</p><p><b>RESULTS</b>Seven vertebrae with satisfactory postural reduction were treated with PVP, 13 vertebrae with unsatisfactory postural reduction were treated with PKP, 3 patients with spinal cord injury were treated with decompression and posterior short segment fixation at the same time. All patients were followed up from 10 to 48 months with an average of 21.2 months. Cement leakage occurred in 4 cases with no symptom, 1 cases in PVP group and 3 cases in PKP group, there was no significant difference between two groups(=0.561). The priming volume of cement was (6.40±0.94) ml in PVP group and (5.46±1.09) ml in PKP group (>0.05). Three days after operation vs preoperation, the vertebral height restoration and kyphotic improvement was(31.71±11.35)%, (9.79±4.64)° in PVP group and (24.77±8.51)%, (8.15±2.97)° in PKP. There was no significant difference between two groups(>0.05). Three days after operation, VAS of low back pain and ODI in all patients were improved than preoperative data(<0.05), but there was no significant difference between two groups or between postoperative at 3 d and final follow up(>0.05). Nerve function of 3 patients underwent decompression and fixation from Frankel D to E.</p><p><b>CONCLUSIONS</b>According to Li staging system and the degree of introperative postural reduction, individualized surgical treatment for Kümmell's disease can obtain good clinical results. Bad postural reduction during operation maybe a risk factor of cement leakage.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the effects and clinical prognosis of out-patient department-based smoking cessation services for coronary heart disease (CHD) patients.</p><p><b>METHODS</b>A total of 140 smoking patients diagnosed with coronary heart disease in our cardiovascular department were randomly divided into the intensive smoking cessation clinic follow-up group (intervention group, patients were informed on the importance and methods to quit smoking at the first visit and reminded for that at months interval for 6 months, n = 70) and the conventional treatment group (control group, n = 70). After 6 months, the smoking status, cardiovascular event rates, drug usage, out-patient medical costs and quality of life were compared between the two groups.</p><p><b>RESULTS</b>Age, gender, concomitant diseases, drug usage were similar between the two groups at baseline (all P > 0.05). After 6 months, smoking quit rate [34.2% (24/70) vs. 5.7% (4/70), P < 0.01], drug use rates: lipid-lowering drugs [95.3% (67/70) vs. 80.4% (56/70)], β blockers [82.4% (57/70) vs. 41.3% (28/70)], and ACEI/ARB [61.4% (43/70) vs. 34.4% (24/70)] were significantly higher in the intervention group than in the control group, while total cardiovascular event rates [21.4% (15/70) vs. 47.1% (33/70), P < 0.01] and out-patient medical costs (3789.3 RMB vs. 4984.2 RMB, P < 0.01) were significantly lower in the intervention group than in the control group. The quality of life scores derived from MYO health survey questionnaire was significantly higher in the intervention group than in the control group (P < 0.01). The top three reasons responsible for continuous smoking for all patients failed to quit smoking were: (1) others smoked more than me and still alive and healthy [90.3% (56/62)]; (2) smoking helped me to keep relaxed and reduce trouble in daily work and life [70.9% (44/62)]; (3) smoking was essential while chatting and drinking with friends [66.1% (41/62)]. The overall satisfactory rate to this smoking cessation program was 42.8% and the satisfactory rate was up to 50.0% by patients.</p><p><b>CONCLUSIONS</b>Intensive outpatient smoking cessation follow-up program can significantly improve the smoking cessation rates, the guideline drug use rate and the quality of life while reduce medical costs for coronary heart disease patients.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the basic characteristics of passive smoking population, and the impact of passive smoking on heart rate variability, heart rate and blood pressure.</p><p><b>METHODS</b>Eighty-six passive smokers [mean age: (52.4 ± 7.6) years] were recruited from patients and their relatives who visited cardiovascular outpatient department and excluded structural heart disease between June 2010 and June 2012, 80 normal subjects who were not exposed to smoking served as controls. Questionnaire survey, 24 hours ambulatory electrocardiogram examination and blood pressure measurement were performed in all recruited subjects.</p><p><b>RESULTS</b>(1) Non-marriage rate [18.60% (16/86) vs. 3.75% (3/80), P < 0.01] was significantly higher while education level were significantly lower in passive smoking group than in control group. Passive smokers were more likely service industry workers [29.07% (25/86) vs. 15.00% (12/80), P < 0.05] and had longer daily working time [(7.56 ± 1.24) h vs. (6.02 ± 0.96) h, P < 0.01], and were less likely to be professional technology industry employers [20.93% (18/86) vs. 36.25% (29/80), P < 0.05] and managers [13.95% (12/86) vs. 38.75% (31/80), P < 0.01] compared to controls. The main place of passive smoking was workplace (67.44%, 58/86), entertainment venues (63.95%,55/86), restaurants (48.84%, 42/86). (2) Standard of the normal sinus RR intervals (SDNN), the normal consecutive sinus RR interval difference between the root-mean-square (rMSSD) and adjacent the difference between the RR interval>50 ms the number of share the percentage (PNN50) were significantly lower in passive smoking group than in the control group (all P < 0.05). Every 5 min average of the standard deviation of sinus RR cycle (SDNN index) and 24 h every 5 min sinus RR interval mean standard deviation (SDANN) were similar between the 2 groups (all P > 0.05). Ultra-low-frequency power (VLF), low frequency power (LF), high frequency power (HF) and LF/HF were significantly lower in passive smoking group than in the control group (all P < 0.01). (3) Heart rate and diastolic blood pressure were significantly higher in passive smoking group than in control group (all P < 0.05) while systolic blood pressure was similar between the 2 groups (P > 0.05).</p><p><b>CONCLUSIONS</b>Marriage status, education level, profession and daily working time are independent determinants for passive smoking. Passive smoking mainly occurred in the workplace, entertainment venues and restaurants. Passive smoking is linked with reduced heart rate variability, increased 24 h average heart rate and diastolic blood pressure.</p>

Data on arrhythmia types, blood pressure, thyroid disease, respiratory sleep apnea syndrome, smoking history, history of alcohol consumption, eating habits, family history of early-onset arrhythmia, laboratory tests were analyzed.</p><p><b>RESULTS</b>(1) Arrhythmia was detected in 110 out of young ACS patients (55%), which was significantly lower than that in the elderly ACS patients (71.05%, P < 0.01). (2) The top three arrhythmias in young ACS patients were: sinus tachycardia (30.50%), the premature ventricular contractions (19.00%), atrial flutter/atrial fibrillation (16.50%). Incidence of sinus tachycardia, atrial flutter/atrial fibrillation were significantly higher while incidence of ventricular tachycardia, ventricular fibrillation, paroxysmal supraventricular tachycardia were significantly lower in young ACS patients than in middle-aged ACS patients (all P < 0.05). The incidence of sinus tachycardia was higher while incidence of ventricular premature accelerated ventricular spontaneous cardiac rhythm, ventricular tachycardia, ventricular fibrillation, non-paroxysmal supraventricular tachycardia, atrial flutter/atrial fibrillation, paroxysmal supraventricular tachycardia, sinus bradycardia, nodal escape, atrioventricular block were significantly lower in young ACS patients than in elderly ACS patients (all P < 0.05). (3) Body mass index, incidence of smoking, coronary three-vessel disease, drinking, eating salty foods, thyroid dysfunction, sleep apnea were significantly higher in youth ACS patients with arrhythmia than in young ACS patients without arrhythmia (all P < 0. 05). (4) Logistic regression analysis found that number of diseased coronary vessels (OR = 24.293), smoking (OR = 1.112) and alcohol consumption (OR = 1.039) were independent risk factor for developing arrhythmia in young ACS patients from Henan province.</p><p><b>CONCLUSIONS</b>The main types of arrhythmia are sinus tachycardia, premature ventricular contractions, atrial flutter/atrial fibrillation and the major risk factors related to the arrhythmia are number of diseased coronary vessels, smoking and alcohol consumption in young ACS patients from Henan province.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To study the therapeutic effect of combined therapy with Chinese drugs and immuno-suppressors, mainly anti-lymphocyte globulin/anti-thymus globulin (ALG/ATG), for the treatment of severe aplastic anemia (SAA), the efficacy associated factors and adverse effects as well.</p><p><b>METHODS</b>A retrospective analysis was conducted on 65 patients with SAA treated by combined therapy which was supplemented with cyclosporin A, androgen, hematopoietic growth factor, etc.</p><p><b>RESULTS</b>Of the 57 patients followed-up, 26 (45.6%) were basically cured, 15 (26.3%) remitted, and 8 (14.0%) improved markedly, the total effective rate being 85.9%. By separately comparing with a single item of clinical data, it was shown that the therapeutic effectiveness was correlated, to a certain extent, with age, illness duration, neutrophil count, and bone marrow proliferation in patients before treatment, as well as with infection that occurred in the follow-up period. It was obviously higher in patients with peripheral neutrophil count > 0.5 x 10 10(9)/L (P<0.05). Various degrees of serum sickness-like reactions occurred in the treatment of 36 patients, including fever in 36 (63.2%), skin rash in 8 (14.0%), and musculoskeletal pain in 5 (8.8%).</p><p><b>CONCLUSIONS</b>The therapeutic effect of combined therapy with Chinese drugs and ALG/ATG in treating SAA could be affirmed, showing some superiority as compared with Western medicine alone. The patients' age, duration of illness, neutrophil count, and bone marrow proliferation before treatment, and degree of infection that occurred could affect the therapeutic efficacy to a certain extent. Adverse reactions resulting from the combined therapy are less, showing the toxicity reducing and effect enhancing action of Chinese drugs.</p>

ABSTRACT

<p><b>OBJECTIVE</b>Type III glycogen storage disease (GSD-III, McKusick 232400), is a rare autosomal recessive disorder, also known as Cori's or Forbe's disease. The affected enzyme is amylo-1,6-glucosidase, 4-alpha-glucanotransferase (glycogen debrancher enzyme, GDE or amylogluco-sidase, AGL), which is responsible for the debranching of the glycogen molecule during catabolism. The AGL gene is located on chromosome 1p21 and contains 35 exons translated in a monomeric protein product. The clinical manifestations of GSD-III are represented by hepatomegaly, recurrent hypoglycemia, seizures, growth failure, dysmorphism, hyperlipidemia, raised transaminases and creatine kinase concentrations and, in a number of subjects, myopathy and cardiomyopathy. The hepatocellular adenoma, hepatocellular carcinoma, diabetes mellitus and liver fibrosis remain rare events. The diagnosis of debrancher deficiency was established by laboratory tests, electromyography (EMG), and muscle and liver biopsy.</p><p><b>METHODS</b>We studied six GSD-III families after patients or parental consent and the clinical characteristics were documented. Analysis of 33 exons and part exon-intron boundaries of the AGL gene in patients and their parents were carried out by PCR and direct DNA sequencing.</p><p><b>RESULTS</b>The clinical features included hepatomegaly, splenomegaly, recurrent hypoglycemia, hyperlipidemia, growth failure, raised transaminases and acidosis. Administration of epinephrine 2 hours after a carbohydrate meal could provoke normal rise of blood glucose in the affected individuals, but could not evoke any response after overnight fasting. Administration of raw-corn-starch could maintain normoglycemia and improve the disease condition. Mutation analysis for patient 1 was normal. Patient 2 had a compound heterozygote: a C-to-T transition at nucleotide 1294 (come from father, 1294C > T, L 298 L) in exon 8 and a G-to-T transition at nucleotide 4747 (from mother, 4747G > T, E1450X) in exon 34. Patient 3 had a compound heterozygote: a C-to-T transition at nucleotide 1294 (from father, 1294C > T, L 298 L) in exon 8 and a G-to-A transition at nucleotide -10 (from mother, -10G > A) in exon 3. Patient 4 was a homozygote: an insertion of a nucleotide CT into position +65 in exon 35 (4664 ins CT). Patient 5 had a compound heterozygote: a 8 bp deletion at nucleotide 2341 (from father, 2341delGCCATAGA, frameshift mutation) in exon 16 and a G-to-A transition at nucleotide 1559 (from mother, 1559G > A, R 387 Q) in exon 10. Patient 6 had a compound heterozygote: a T-to-G transition at nucleotide 1686 (from mother, 1686T > G, Y429 X) in exon 12 and a G-to-A transition at nucleotide 3742 (from father, 3742G > A, G 1115 R) in exon 26.</p><p><b>CONCLUSION</b>GSD-III patients have variable phenotypic characteristics. Administration of raw-corn-starch can effectively improve the disease outcome. We identified 8 new mutations on AGL gene through nucleotide sequence analysis.</p>
