BACKGROUNDNitroglycerin (NTG) is one of the few immediate treatments for acute angina. Aldehyde dehydrogenase 2 (ALDH2) is a key enzyme in the human body that facilitates the biological metabolism of NTG. The biological mechanism of NTG serves an important function in NTG efficacy. Some reports still contradict the results that the correlation between ALDH2 gene polymorphisms and NTG and its clinical efficacy is different. However, data on NTG measurement by pain relief are subjective. This study aimed to investigate the influence of ALDH2 gene polymorphism on intervention with sublingual NTG using noninvasive hemodynamic parameters of cardiac output (CO) and systemic vascular resistance (SVR) in Northern Chinese Han population.

METHODSThis study selected 559 patients from the Affiliated Hospital of Qingdao University. A total of 203 patients presented with coronary heart disease (CHD) and 356 had non-CHD (NCHD) cases. All patient ALDH2 genotypes (G504A) were detected and divided into two types: Wild (GG) and mutant (GA/AA). Among the CHD group, 103 were wild-type cases, and 100 were mutant-type cases. Moreover, 196 cases were wild-type, and 160 cases were mutant type among the NCHD volunteers. A noninvasive hemodynamic detector was used to monitor the CO and the SVR at the 0, 5, and 15 minute time points after medication with 0.5 mg sublingual NTG. Two CO and SVR indicators were used for a comparative analysis of all case genotypes.

RESULTSBoth CO and SVR indicators significantly differed between the wild and mutant genotypes at various time points after intervention with sublingual NTG at 5 and 15 minutes in the NCHD (F = 16.460, 15.003, P = 0.000, 0.000) and CHD groups (F = 194.482, 60.582, P = 0.000, 0.000). All CO values in the wild-type case of both NCHD and CHD groups increased, whereas those in the mutant type decreased. The CO and ΔCO differences were statistically significant (P < 0.05; P < 0.05). The SVR and ΔSVR changed between the wild- and mutant-type cases at all-time points in both NCHD and CHD groups had statistically significant differences (P < 0.05; P < 0.05).

CONCLUSIONALDH2 (G504A) gene polymorphism is associated with changes in noninvasive hemodynamic parameters (i.e. CO and SVR) after intervention with sublingual NTG. This gene polymorphism may influence the effect of NTG intervention on Northern Chinese Han population.

Background/Aims: The gastrointestinal symptom of diabetes mellitus, chronic constipation, seriously affects patients’ life. Whereas, the mechanism of chronic constipation is still ambiguous, resulting in a lack of effective therapies for this symptom. As a part of the smooth muscle cells, interstitial cells of Cajal, and platelet-derived growth factor receptor alpha-positive (PDGFRα+ ) cells syncytium (SIP syncytium), PDGFRα+ cells play an important role in regulating colonic motility. According to our previous study, in PDGFRα+cells in colons of diabetic mice, the function of the P2Y1 purinergic receptor/type 3 small-conductance calcium-activated potassium (SK3) channel signaling pathway is strengthened, which may lead to colonic dysmotility. The purpose of this study is to investigate the changes in SK3 channel properties of PDGFRα+ cells in diabetic mice. Methods: Whole-cell patch clamp, Western blotting, superoxide dismutase activity measurement, and malondialdehyde measurement were main methods in the present study. Results: The present study revealed that when dialysed with low calcium ion (Ca 2+ ) solution, the SK3 current density was significantly decreased in PDGFRα+ cells from diabetic mice. However, the SK3 current density in PDGFRα+ cells was enhanced from diabetic mice when dialysed with high Ca 2+ solution. Moreover, hydrogen peroxide-treatment mimicked this phenomenon in SK3 transgenic HEK293 cells. The subunit of SK3 channels, protein kinase CK2, was up-regulated in colonic muscle layers and hydrogen peroxidetreated HEK293 cells. Additionally, protein phosphatase 2A, the subunit of SK3 channels, was not changed in streptozotocin-treated mouse colons or hydrogen peroxide-treated HEK293 cells. Conclusion The diabetic oxidative stress-induced upregulation of CK2 contributed to modulating SK3 channel sensitivity to Ca 2+ in colonic PDGFRα+ cells, which may result in colonic dysmotility in diabetic mice.

Gastrointestinal smooth muscle layer contains two kinds of interstitial cells with special differentiation, i.e., interstitial cells of Cajal (ICC) and platelet-derived growth factor receptor α-positive (PDGFRα) cells. The ICC and PDGFRαcells contact with smooth muscle cells (SMCs) by gap junctions and regulate contractive function of the SMCs. Therefore, these three kinds of cells constitute a functional syncytium, i.e., the SMC, ICC and PDGFRαcells syncytium (SIP syncytium). Various neurotransmitters, humoral factors, endogenous bioactive molecules, as well as drugs regulate gastrointestinal motility through the SIP syncytium. In this review, we introduce the concept of SIP syncytium and summarize functions of the syncytium, as well as its physiological and pathological significances.

This study was aimed to investigate a beneficial approach for resolving the deficiency of blood source, preventing the infection resulting from blood transfusion and overcoming the knotty match of patients with rare blood group by using massive expansion of erythroid cells from cord blood CD34(+) cells in vitro. The CD34(+) cells from human cord blood were cultured in serum-free medium supplemented with stem cell factor (SCF), interleukin-3 (IL-3) and erythropoietin (EPO) for 1 week, then expansion and differentiation of CD34(+) cells into erythroid cells were supported by co-culture with human mesenchymal stem cells (MSCs) derived from bone marrow for 2 weeks. The results indicated that after culture for 23 days, the expansion multiple of total cell number reached 2.52 x 10(5), and over 95% of these cells were erythroid cells as compared with less than 1% of myelomonocytic (CD14(+) or CD15(+)) cells and megakaryocytic (CD41(+)) cells. However, the culture system without MSC support was significantly disadvantaged both in expansion ability and ratio of erythroid cells when compared with MSC supporting system. It is concluded that the erythroid cells can be produced from CD34(+) cells in large scale by culturing in the system comprised of cytokine sets and MSC feeders, in which MSCs can support the proliferation and differentiation of erythroid cells.

In 2004, it was the first time that Wollensak and Spoerl had applied physical and chemical cross-linking methods to scleral tissue. They found that the biomechanical strength of cross-linked sclera, induced by riboflavin/ultraviolet A, glyceraldehyde and glutaraldehyde, could be improved and proposed that scleral collagen cross-linking is expected to be a new method for the treatment of pathologic myopia. In recent years, a series of explorations have been made on the effectiveness and adverse reactions of physical and chemical cross-linking in the prevention and treatment of pathologic myopia, including the establishment of various animal models and different myopia modeling methods, the improvement of cross-linking methods, the amelioration of the measurement of biomechanical strength of scleral tissue and the attention of biological parameters such as the thickness of retinal nerve fiber layer and the amplitude of electroretinogram in vivo. Genipin-crosslinking of the scleral collagen combined with posterior scleral contraction/reinforcement has been applied to clinical research. This review summarizes physical cross-linking and the genipin-crosslinking of scleral collagen to explore the effectiveness and safety of the methods in the prevention and treatment of the pathologic myopia.

AIM:A total of 1 084 preschool children in 4 kindergartens in Xining City were surveyed on their visual acuity and refraction status to find out abnormal vision and refraction beyond the normal range. METHODS: A cross-sectional survey study. The overall sampling method was used on October 2019, a total of 1 084 preschool children aged 3-6 years were selected from a kindergarten in the east, west, south and north of Xining City. The children were checked for uncorrected distance vision and refractive status was checked by using a refractive screener.RESULTS: The detection rate of abnormal vision in preschool children in Xining City was 12.21%, and the detection rate of abnormal vision increased with the increasing age(χ2lineartrend=94.40, P<0.05), and there were differences among different age groups(χ2=293.55, P<0.05). Refractive abnormalities accounted for 6.09% of the total number of examinations. With the increasing age, the proportion of compound hyperopic astigmatism decreased(χ2lineartrend=1.79, P>0.05).CONCLUSION: The abnormal visual acuity of preschool children in Xining City gradually increases with the increasing age; The refractive state is dominated by astigmatism, among which the proportion of mixed astigmatism and pure myopia astigmatism is the highest, followed by pure hyperopic astigmatism and compound hyperopic astigmatism; With the increase of age, the diopter of compound hyperopic astigmatism gradually decreases, which is in line with the law of children's eye refractive development.

Background:The increasing prevalence of colorectal cancer (CRC) in China and the paucity of information about relevant expenditure highlight the necessity of better understanding the financial burden and effect of CRC diagnosis and treatment.We performed a survey to quantify the direct medical and non-medical expenditure as well as the resulting financial burden of CRC patients in China.Methods:We conducted a multicenter,cross-sectional survey in 37 tertiary hospitals in 13 provinces across China between 2012 and 2014.Each enrolled patient was interviewed using a structured questionnaire.All expenditure data were inflated to the 2014 Chinese Yuan (CNY;1 CNY =0.163 USD).We quantified the overall expenditure and financial burden and by subgroup (hospital type,age at diagnosis,sex,education,occupation,insurance type,household income,clinical stage,pathologic type,and therapeutic regimen).We then performed generalized linear modeling to determine the factors associated with overall expenditure.Results:A total of 2356 patients with a mean age of 57.4 years were included,57.1％ of whom were men;13.9％ of patients had stage Ⅰ cancer;and the average previous-year household income was 54,525 CNY.The overall average direct expenditure per patient was estimated to be 67,408 CNY,and the expenditures for stage Ⅰ,Ⅱ,Ⅲll,and Ⅳ disease were 56,099 CNY,59,952 CNY,67,292 CNY,and 82,729 CNY,respectively.Non-medical expenditure accounted for 8.3％ of the overall expenditure.The 1-year out-of-pocket expenditure of a newly diagnosed patient was 32,649 CNY,which accounted for 59.9％ of their previous-year household income and caused 75.0％ of families to suffer an unmanageable financial burden.Univariate analysis showed that financial burden and overall expenditure differed in almost all subgroups (P ＜ 0.05),except for sex.Multivariate analysis showed that patients who were treated in specialized hospitals and those who were diagnosed with adenocarcinoma or diagnosed at a later stage were likely to spend more,whereas those with a lower household income and those who underwent surgery spent less (all P ＜ 0.05).Conclusions:For patients in China,direct expenditure for the diagnosis and treatment of CRC seemed catastrophic,and non-medical expenditure was non-ignorable.The financial burden varied among subgroups,especially among patients with different clinical stages of disease,which suggests that,in China,CRC screening might be cost-effective.
