ABSTRACT
AIM: To compare the changes in retinal nerve fiber layer(RNFL)and macular ganglion cell complex(GCC)measured by spectral domain optical coherence tomography(SD-OCT)in non-glaucoma subjects with low, moderate, and high myopia.METHODS: A total of 400 subjects(400 eyes)with myopia who attended our hospital from December 2019 to November 2022 were selected to participate in this study, and the subjects were divided into the following groups according to their degree of myopia: low myopia group(142 cases, 142 eyes, 35.5%), moderate myopia group(139 cases, 139 eyes, 34.8%)and high myopia group(119 cases, 119 eyes, 29.8%). RNFL thickness profiles were measured, including mean, superior, inferior, nasal, and temporal RNFL thickness. GCC parameters were measured, including mean, superior, superior temporal, inferior, inferior temporal, superior nasal, and inferior nasal. Correlation between RNFL thickness measured by OCT, mean GCC parameters, and axial length was evaluated.RESULTS: The mean RNFL thickness above, below and nasal side was significantly higher in the low and moderate myopia groups and the temporal RNFL thickness was significantly lower than the high myopia group(all P<0.05); the mean GCC thickness above, above temporal, below, below temporal, above nasal, below nasal and mean GCC thickness were significantly higher in the low and moderate myopia groups than in the high myopia group(all P<0.05); In the moderate myopia group, the mean RNFL and GCC thickness were both negatively correlated with axial length(r=-0.387, -0.309, all P<0.05). In the high myopia group, both RNFL and GCC thickness means were negatively correlated with eye axis length(r=-0.499, -0.503, all P<0.01).CONCLUSION:RNFL and GCC thicknesses tend to be thinner in subjects with high myopia than in subjects with low and moderate myopia.
ABSTRACT
Autophagy and inflammation are the important physiological reactions, especially in innate immunity. Autophagy, as a conservative metabolic process, can degrade its own disorder components through lysosomes to maintain cell homeostasis. Autophagy plays a pivotal role in degrading damaged organelles, resisting pathogenic infection and regulating inflammatory response. In the past decades, the study of autophagy in yeast and mammals has greatly increased our understanding for autophagy and its relationship with the diseases. In human, the regulation on autophagy levels can be used to prevent or treat neurodegenerative diseases, inflammatory diseases, tumors and various pathogenic microbial infections. However, in fish, the researches on autophagy and application are limited. Inflammation is a highly complex biological process, which is a natural defense response under the stimulation of ultraviolet, pathogen infection, oxidative stress and mechanical damage. Fish, as a lower vertebrate, has an incomplete acquired immune system. Innate immunity plays an important role in defensing against pathogen infection. Compared with higher vertebrate animals, although the researches on autophagy in fish cells were carried out lately, the great progress has been made in recent years on autophagy phenomenon, expression regulation of autophagy-related genes, and mechanism caused by pathogenic infection. As an important part of innate immunity, autophagy is involved in a variety of fish pathogenic infections, and fish diseases are usually accompanied by inflammatory reaction. In this review, we summarized the update findings in recent references on the autophagy and inflammatory response caused by pathogenic infection in fish, and the correlation between them, in order to deeply understand the correlation relationship between autophagy and inflammatory response in fish. This review could provide the guidance for understanding the immune mechanism of fish, and supply the foundation for developing new strategy to prevent and control fish disease.
ABSTRACT
@#AIM: To analyze the changes of the epiretinal membrane(ERM)stage, macular status and best corrected visual acuity(BCVA, LogMAR)in cataract patients with idiopathic macular epiretinal membrane(IERM)before and after cataract surgery.METHODS:We conducted a single center retrospective observational case series of patients that underwent sequential cataract and idiopatic ERM surgeries from March 2016 to May 2019 in Anyang Eye Hospital. Full data were obtained for 51 patients(54 eyes).Preoperative and postoperative 1mo ERM stage, central macular edema(CME), central macular thickness(CMT), macular volume(MV), ellipsoid zone disruption, occurrence of neurosensory detachment(NSD)and BCVA were analyzed.RESULTS:In this group of patients, 5 eyes(9%)had ERM grade 1, 23 eyes(43%)had ERM grade 2, 21 eyes(39%)had ERM grade 3, and 5 eyes(9%)had ERM grade 4 before surgery; ERM graded 1mo after surgery were keeping steady. Compared with before operation(0.45±0.16),there was no significant change in BCVA(0.47±0.17)at 1mo after operation(<i>P</i>>0.05), but the incidence of CME, ellipsoid band interruption and NSD were significantly higher than those before operation(<i>P</i><0.05). CONCLUSION: We suggest that phacoemulsification did not significantly accelerate ERM progression and affect BCVA, but patients underwent cataract surgery in the presence of epiretinal membranes need tight follow up to treat and control eventual macular infammatory changes and eventual prompt vitrectomy if BCVA was threatened.
ABSTRACT
Venous thromboembolism (VTE) is one of the common complications of lung adenocarci-noma. The state of the driver genes of lung adenocarcinoma is related to the risk of VTE. The common driver genes include epidermal growth factor receptor, anaplastic lymphoma kinase, c-ros oncogene 1 receptor kinase and Kirsten rat sarcoma viral oncogene, etc.. Based on the study of the correlation between lung adenocarci-noma driver genes and VTE, it is of great significance for the early clinical prevention of VTE in patients with lung adenocarcinoma to screen out patients with high risk of VTE according to the state of the driver genes and finally evaluate the risk of VTE in patients with lung adenocarcinoma by combining conventional risk factors with the driver genes.
ABSTRACT
Cerebral ischemia/reperfusion injury (CIRI) is a common feature and the main pathophysiological mechanism of ischemic stroke(IS), which is caused by a blood reperfusion injury in ischemic brain tissues. It can aggravate brain tissue injury and cause irreversible brain damage, seriously affecting the quality of life or even the life of patients. Hence, we must find out the exact mechanism as well as the effective therapeutic drugs and targets for CIRI. The Chinese medicine effective in Xingnao (restoring consciousness) and Kaiqiao (opening orifices) has been widely used in the treatment of CIRI and serves as a classic therapy for IS. In recent years, scholars have conducted extensive and in-depth studies on the mechanism and therapeutic targets of Chinese medicine in Xingnao and Kaiqiao. They found that those drugs could interfere with a series of changes after IS and achieve the remarkable curative effect. This study summarized the effect and mechanism of Chinese medicine in Xingnao and Kaiqiao in the treatment of CIRI, including reducing the inflammatory response and oxidative stress, alleviating brain edema and the toxicity of excitatory amino acids, reducing cell apoptosis, promoting angiogenesis and neurovascular remodeling, and improving blood-brain barrier injury. It is expected to provide references to clarify the mechanism and important targets of those drugs in resisting CIRI and ideas for the in-depth investigation and application of brain protection of Chinese medicine in Xingnao and Kaiqiao.
ABSTRACT
At present, the research of Moutan cortex carbonisata (MCC) mainly focuses on the changes of chemical composition before and after charcoal production, and there is a lack of material basic research directly related to the efficacy at home and abroad. In this study, Moutan cortex, as a precursor, and was calcined to MCC at high temperature. The Moutan cortex carbonisata nano-components (MCC-NCs) were extracted and separated from MCC to explore its cooling-blood and hemostatic effects. In the experiment, the MCC was calcined at a high temperature in a muffle furnace (350 ℃, 1 h), and then MCC-NCs were extracted for MCC, and characterized by transmission electron microscopy and UV-vis absorption spectroscopy, fluorescence spectroscopy, Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy. In addition, the study evaluated the blood-cooling and hemostatic effects of MCC-NCs. The results showed that MCC-NCs have a size distribution of 0.80-2.8 nm, a lattice spacing of 0.26 nm. MCC-NCs are mainly composed of C, O and N elements and have abundant surface functional groups such as OH, C=O, C-N and C=C. The fluorescence yield of MCC-NCs was 7.18%. The experiments complied with the Animal Ethics Committee of Beijing University of Chinese Medicine. The result indicated that pretreatment MCC-NCs can significantly (P < 0.05) reduce the high, medium, and low viscosity of whole blood and plasma viscosity, and reduce hematocrit, red blood cell distribution width, hemoglobin and red blood cell level. In addition, MCC-NCs significantly reduced the levels of activated partial thromboplastin time, thrombin time and fibrinogen (P < 0.05). The pathological examination results showed that MCC-NCs can significantly reduce lung tissue damage, reduce bleeding and inflammatory cell infiltration. At the same time, it can also significantly reduce the symptoms of gastric mucosal bleeding. In conclusion, the results indicated that MCC-NCs has significantly the effect of blood cooling and hemostasis, and its hemostatic effect is mainly related to the activation of endogenous coagulation pathway or fibrinogen system, which provided a novel strategy for exploring the material basis of traditional Chinese medicine for hemostasis.

ABSTRACT
Objective To summarize the clinical characteristics of papillary thyroid microcarcinoma with diameter ≤ 5 mm. Methods The clinical data of 259 papillary thyroid microcarcinoma patients who had underwent radical thyroidectomy from January 2015 to December 2017 were retrospectively analyzed. The patients were divided into 2 groups according to the preoperative tumor diameter: >5 mm group (88 cases) and ≤ 5 mm group (171 cases); then according to the lymph node metastasis, the 2 groups were divided into non-lymph node metastasis sub-group and lymph node metastasis sub-group. The reason of lymph node metastasis was analyzed. Results There were no statistical difference in gender composition, age and combined Hashimoto thyroiditis rate between >5 mm group and≤5 mm group (P>0.05). The rates of T3-4 stage, N1a-1b stage and multifocal tumors in>5 mm group were significantly higher than those in ≤ 5 mm group: 34.1% (30/88) vs. 18.7% (32/171), 45.5% (40/88) vs. 22.8% (39/171) and 39.8% (35/88) vs. 22.8% (39/171), and there were statistical differences (P<0.05 or<0.01). In>5 mm group, lymph node metastasis sub-group had 40 cases, non-lymph node metastasis sub-group had 48 cases; the rate of T3-4 stage in lymph node metastasis sub-group was significantly higher than that in non-lymph node metastasis sub-group: 55.0% (22/40) vs. 16.7% (8/48), and there was statistical difference (P<0.01). In≤5 mm group, lymph node metastasis sub-group had 39 cases, and non-lymph node metastasis sub-group had 132 cases; the rate of T3-4 stage in lymph node metastasis sub-group was significantly higher than that in non-lymph node metastasis sub-group:51.3% (20/39) vs. 9.1% (12/132), and there was statistical difference (P<0.01). In>5 mm group and≤5 mm group, there were no statistical difference in gender composition, age, combined Hashimoto thyroiditis rate and multifocal tumors rate between 2 sub-groups (P>0.05). Conclusions The clinical behavior of papillary thyroid microcarcinoma with diameter ≤ 5 mm has a less aggressive nature compared to that>5 mm. Tumor capsular invasion or extra thyroidal extension has a great influence on lymph node metastasis in thyroid papillary microcarcinoma of different diameter.
ABSTRACT
Isopropylidene shikimic acid [ISA], a new drug derviatived from Shikimic Acid, had been proved to be effective in the cerebral protection after cerebral ischemia and reperfusion. But there was little research on the physical pharmacy and biopharmaceutical properties about the drug. In order to provide some useful data for the pharmaceutical development of ISA, the solubility, stability and Oil/Water partition coefficient [LogP] were determined by the classic preformulation study method, and the transmembrane performance of ISA was studied by Franz -diffusion cell method in vitro. The results showed that ISA was water-soluble with a solubility 32.52mg/ml, which could be improved to 44.32 mg/ml by 1% [w/v] sodium dodecyl sulfate; the LogP was -0.63; ISA was less stable in water but it was stable when pH greater than 6.0 and unstable when pH less than 6.0; the accumulated permeation rates at 1h were about 50% and more than 80% at 6h. Data obtained by the study indicated that the medium selection and pH control were important for liquid preparation of ISA, and avoiding dissolution and absorption in stomach was critical for the oral solid dosage forms. Mucosal drug delivery systems would be considered, according to the certain hydrophilic-lipophilic characters and good transmembrane capability
ABSTRACT
The fruiting body pattern is an important agronomic trait of the edible fungus Auricularia auricula-judae, and an important breeding target. There are two types of fruiting body pattern: the cluster type and the chrysanthemum type. We identified the fruiting body pattern of 26 test strains, and then constructed two different near-isogenic pools. Then, we developed sequence characterized amplified region (SCAR) molecular markers associated with the fruiting body pattern based on sequence-related amplified polymorphism (SRAP) markers. Ten different bands (189–522 bp) were amplified using 153 pairs of SRAP primers. The SCAR marker “SCL-18” consisted of a single 522-bp band amplified from the cluster-type strains, but not the chrysanthemum strains. This SCAR marker was closely associated with the cluster-type fruiting body trait of A. auricula-judae. These results lay the foundation for further research to locate and clone genes controlling the fruiting body pattern of A. auricula-judae.

<p><b>OBJECTIVE</b>To study the pharmacokinetics of puerarin (PUE) in Gegen Qinlian Decoction (, GQD), and the effects of PUE dosage variations on the pharmacokinetics of baicalin (BAL) in mice.</p><p><b>METHODS</b>GQD is composed of the concentrated granules of four Chinese herbs. Three dosages with different levels of PUE, including GQD, GQD co-administered with PUE, and GQD co-administration with two times the amount of PUE, were used to research the pharmacokinetics of PUE and BAL in mice. The indirect competitive enzyme-linked immunosorbent assay (icELISA) methods based on an anti PUE-monoclonal antibody (MAb)and BAL-MAb were employed to determine the concentration of PUE and BAL in mice blood.</p><p><b>RESULTS</b>After the co-administration of GQD with PUE, the area under the curves (AUC) of PUE increased 2.8 times compared with GQD. At the dose of GQD co-administration at two times that of PUE, the (AUC) of PUE was almost equal to that of GQD co-administration of PUE, showing non-linear pharmacokinetics. The (AUC) of BAL showed a good dose-related increase of PUE (r=0.993) in the range from 100 to 300 mg/kg, indicating that PUE dramatically affects the absorption of BAL in mice. There was no significant difference in the other pharmacokinetic parameters, such as the first time of maximum concentration (T), the second T, or the mean residence time.</p><p><b>CONCLUSIONS</b>The icELISA methods were successfully applied to pharmacokinetic studies of PUE and BAL in GQD in mice. The dosage variability of PUE of the main ingredient in GQD affects its own pharmacokinetic characteristics and the absorption characteristics of BAL.</p>
