Objective To investigate the factors influencing prognosis in patients with acute myocardial infarction complicated with cardiogenic shock undergoing primary percutaneous coronary intervention(PPCI).Methods Patients with acute myocardial infarction complicated with cardiogenic shock who underwent PPCI at our hospital between January 2015 and December 2019 were enrolled.Clinical baseline characteristics,coronary angiography and PCI-related parameters,and mechanical support information were collected.The patients were followed up for one year and divided into survival and death groups based on their survival status within one year.Differences in various factors between the two groups were compared.Results A total of 40 patients were enrolled,including 26 in the survival group and 14 in the death group.There were no differences in baseline data,diagnosis,risk factors,and comorbidities between the two groups.The survival group had a lower heart rate and higher blood pressure trend at admission compared to the death group.Myocardial enzymes were significantly lower in the survival group compared to the death group(median CK peak:496.00(198.25,2 830.00)U/L vs.3 040.00(405.75,5 626.53)U/L,P=0.003;median CK-MB peak:52.65(31.75,219.50)U/L vs.306.00(27.25,489.63)U/L,P=0.006).When comparing coronary angiography and PCI-related indicators between the two groups,the survival group had a higher rate of complete revascularization compared to the control group(53.85％vs.21.43％,P=0.048).The survival group had a higher proportion of extracorporeal membrane oxygenation(ECMO)combined with intra-aortic balloon pump(IABP)support compared to the control group[38.46％vs.7.14％,P=0.034].Conclusions Survival in patients with acute myocardial infarction complicated with cardiogenic shock undergoing PPCI is associated with lower level of myocardial enzymes,ECMO combined with IABP support and complete revascularization.

In infants with severe bronchopulmonary dysplasia(sBPD),severe pulmonary lobar emphysema may occur as a complication,contributing to significant impairment in ventilation.Clinical management of these infants is extremely challenging and some may require lobectomy to improve ventilation.However,prior to the lobectomy,it is very difficult to assess whether the remaining lung parenchyma would be able to sustain adequate ventilation postoperatively.In addition,preoperative planning and perioperative management are also quite challenging in these patients.This paper reports the utility of selective bronchial occlusion in assessing the safety and efficacy of lobectomy in a case of sBPD complicated by severe right upper lobar emphysema.Since infants with sBPD already have poor lung development and significant lung injury,lobectomy should be viewed as a non-traditional therapy and be carried out with extreme caution.Selective bronchial occlusion test can be an effective tool in assessing the risks and benefits of lobectomy in cases with sBPD and lobar emphysema.However,given the technical difficulty,successful application of this technique requires close collaboration of an experienced interdisciplinary team.

It is well established that increased excitability of the presympathetic neurons in the hypothalamic paraventricular nucleus (PVN) during hypertension leads to heightened sympathetic outflow and hypertension. However, the mechanism underlying the overactivation of PVN presympathetic neurons remains unclear. This study aimed to investigate the role of endogenous corticotropin-releasing factor (CRF) on the excitability of presympathetic neurons in PVN using Western blot, arterial blood pressure (ABP) and renal sympathetic nerve activity (RSNA) recording, CRISPR/Cas9 technique and patch-clamp technique. The results showed that CRF protein expression in PVN was significantly upregulated in spontaneously hypertensive rats (SHRs) compared with normotensive Wistar-Kyoto (WKY) rats. Besides, PVN administration of exogenous CRF significantly increased RSNA, heart rate and ABP in WKY rats. In contrast, knockdown of upregulated CRF in PVN of SHRs inhibited CRF expression, led to membrane potential hyperpolarization, and decreased the frequency of current-evoked firings of PVN presympathetic neurons, which were reversed by incubation of exogenous CRF. Perfusion of rat brain slices with artificial cerebrospinal fluid containing CRF receptor 1 (CRFR1) blocker, NBI-35965, or CRF receptor 2 (CRFR2) blocker, Antisauvagine-30, showed that blocking CRFR1, but not CRFR2, hyperpolarized the membrane potential and inhibited the current-evoked firing of PVN presympathetic neurons in SHRs. However, blocking CRFR1 or CRFR2 did not affect the membrane potential and current-evoked firing of presympathetic neurons in WKY rats. Overall, these findings indicate that increased endogenous CRF release from PVN CRF neurons enhances the excitability of presympathetic neurons via activation of CRFR1 in SHRs.

Autophagic flux refers to a series of dynamic process of autophagic bilayer membrane formation, autophagosome formation, autophagolysosomes formation and degradation. The etiology of cataract is complex, including congenital abnormalities in lens development due to genetic mutations, oxidative damage due to aging, abnormalities in glucose metabolism due to diabetes, and proliferation of lens epithelial cells(LECs)stimulated by postoperative inflammatory factor, all of which are associated with the development of cataracts. A growing number of research in recent years have discovered that altering the status of LECs can contribute to the pathophysiological process of cataract by regulating autophagic flux. This review summarized the impacts of autophagic flux regulation on cataract.

AIM: To investigate the changes of protein expressions in human lens epithelial cells(SRA01/04)undergoing oxidative damage, hoping to provide new protein target for the pathogenesis of age-related cataract(ARC).METHODS: SRA01/04 cells were divided into experimental group and control group. In the experimental group, cells were irradiated with ultraviolet-B(UVB)for 10min to establish the model of oxidative damage, whereas cells in the control group were untreated. Protein expression profile from the two groups was sequenced by isobaric tags for relative and absolute quantitation(iTRAQ). The filtering criteria that fold change >1.2 and p<0.05 was used to determine the differentially expressed proteins(DEPs). Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)database were utilized for functional enrichment analysis of the top 50 DEPs with either up-regulated or down-regulated significance. Furthermore, Pathway commons software was used to establish the protein-protein interaction(PPI)network.RESULTS: Overall, 552 DEPs were screened out. A total of 176 DEPs were up-regulated in the experimental group compared with the control group, including HMGB1 and USP1, while 376 DEPs were down-regulated, including POLR2A and POLR2B. GO and KEGG enrichment analysis indicated that the top 50 DEPs with up-regulated or down-regulated significance were involved in various crucial biological processes and signaling pathways. PPI network revealed that oxidative damage repair(ODR)-related proteins might play a key role in UVB-induced oxidative damage.CONCLUSIONS: The expressions of multiple proteins, especially ODR-related proteins, can be altered in SRA01/04 cells via UVB irradiation. These findings may provide cellular-related insights into the pathogenesis of ARC and into proteins or pathways associated with therapeutic targets.

AIM: To analyze the correlations among parameters from iTrace visual function analyzer, Pentacam 3D anterior segment analysis system and lens opacities classification system(LOCS)Ⅲ in the assessment of lens opacity of age-related cataract(ARC)patients.METHODS: A prospective cross-sectional study. A total of 104 ARC patients(104 eyes)in the department of ophthalmology of our hospital from May to August, 2021 were included. The cataracts of patients were graded based on LOCSⅢ using a slit-lamp. Opacity map grade(OMG)and dysfunctional lens index(DLI)were obtained by iTrace. Pentacam nucleus staging(PNS)and Scheimpflug images of lenses were acquired by Pentacam. The regional integrated density(IntDen)of Scheimpflug images was obtained by ImageJ. The normality and correlations of parameters were analyzed by SPSS 26.0.RESULTS: All the parameters were normally distributed except 3mm IntDen and IntDen of 6mm posterior subcapsular region. PNS positively correlated with nuclear color(NC)and nuclear opalescence(NO)(r=0.521, 0.440, all P<0.01). The 3mm IntDen positively correlated with NC and NO(rs=0.459, 0.450, all P<0.01). IntDen of 3mm nucleus region positively correlated with NC and NO(r=0.539, 0.543, all P<0.01). IntDen of 3mm posterior subcapsular region was negatively correlated with NC and NO(r=-0.315, -0.321, all P<0.01). 6mm IntDen positively correlated with NC and NO(r=0.321, 0.288, all P<0.01). 3mm DLI negatively correlated with NC, NO, and posterior subcapsular cataract(PSC)(r=-0.257, -0.234, -0.282, all P<0.01). 6mm DLI negatively correlated with NC, NO, PSC(r=-0.247, -0.304, -0.227, all P<0.05). 3mm OMG positively correlated with CC and PSC(r=0.268, 0.333, all P<0.01), and 6mm OMG positively correlated with CC and PSC(r=0.275, 0.245, all P<0.05). 3mm DLI negatively correlated with PNS and IntDen of 3mm nucleus region(r=-0.217, -0.197, all P<0.05).CONCLUSION:Each lens opacity assessment system had its own advantages. Taking all parameters into comprehensive consideration is conducive to objectively eraluate the opacity degree of each area of the lens and provide references for clinical work.

Sojae Semen Germinatum was firstly recorded in Shennong Bencaojing， and it has a long history of edible and medicinal use. Most ancient medical practitioners described that Sojae Semen Germinatum was processed with black soya bean， while some others recorded that Sojae Semen Germinatum was processed with black soya bean and soybean or with soybean only. In modern times， black soya bean and soybean are both used. Before the Northern and Southern dynasties， the germination process of Sojae Semen Germinatum was mostly soil culture， and then changed into water culture later. The medicinal part of Sojae Semen Germinatum may also change from the initial aboveground part to the whole processed products including the soybean and the bud. The bud length was used to control the processing ending of Sojae Semen Germinatum， but there were different views of the bud length in ancient and modern times. Before the Tang dynasty， Sojae Semen Germinatum was mostly used directly. Since the Tang dynasty， various subsequent processed products of Sojae Semen Germinatum appeared. Most ancient medical practitioners confirmed that Sojae Semen Germinatum was sweet flavor， neutral in nature and non-toxic， and the mainstream believed that it belonged to the spleen， lung and stomach meridians. However， there were different opinions on its efficacy of relieving exterior syndrome by diaphoresis. In this paper， the evolution of Sojae Semen Germinatum was explored after consulting all kinds of ancient books， its historical name， processing history， quality evaluation and others were systematically summarized in order to clarify its historical development and lay a good foundation for the clinical use and further development of Sojae Semen Germinatum.

OBJECTIVE: To assess the association of apolipoprotein (apo) C1 (APOC1) gene rs4420638A/G and -317H1/H2 polymorphisms with the risk of pre-eclampsia (PE) and the influence of their genotypes on the clinical and metabolic indexes among Chinese women. METHODS: In total 289 PE patients and 824 women with uncomplicated pregnancies were included. The rs4420638A/G genotype was determined by a Taqman real-time PCR allelic discrimination assay. The -317H1/H2 genotype was measured through PCR and restriction fragment length polymorphism analysis. Serum lipid and apo levels were measured by an enzymatic kit and a PEG-enhanced immunoturbidimetric assay. RESULTS: Allelic and genotypic frequencies of the APOC1 gene rs4420638A/G and -317H1/H2 were not significantly different between the two groups (all P> 0.05). However, patients carrying the G allele of the rs4420638A/G locus had higher serum levels of triglyceride, non-HDL-C and apoB, and a higher apoB/apoA1 ratio compared with those with an AA genotype (all P< 0.05). Patients carrying the H2 allele of the -317H1/H2 polymorphism had smaller delivery gestational weeks compared with those with the H1H1 genotype (P< 0.05). CONCLUSION Polymorphisms of the APOC1 gene rs4420638 and -317H1/H2 sites may be associated with abnormal lipoprotein metabolism among Chinese patients with PE, though no association was found between variants of the APOC1 gene and the risk of PE among them.

A contributory role of oxidative stress and protection by antioxidant nutrients have been suspected in cataract formation. Ganoderic acid A (GAA), an effective lanostane triterpene, is widely reported as an antioxidant. The aim of this study is to investigate the potential effects of GAA on cataract formation. After lens epithelial cells (LECs) were exposed to UVB radiation for different periods, cell viability, apoptosis-related protein levels, malondialdehyde (MDA) and superoxide dismutase (SOD) activities were monitored. We found that cell viability, the Bcl-2/Bax ratio and SOD activity were increased, while Cleaved caspase-3 levels and MDA activity were decreased compared with those in UVB-impaired LECs after GAA treated. Furthermore, GAA activated PI3K/AKT in UVB-impaired LECs and effectively delayed the occurrence of lens opacity in vitro. In conclusion, these findings demonstrated that GAA exhibited protective functions in SRA01/04 cells and rat lenses against UVB-evoked impairment through elevating cell viability and antioxidant activity, inhibiting cell apoptosis, activating the PI3K/AKT pathway and delaying lens opacity.

Sojae Semen Germinatum （SSG） was firstly recorded in Shennong Bencaojing. It is a dry processed product which is germinated using mature seeds of Glycine max. It is neutral in nature and sweet flavor， and its functions are to relieve heat， clear away heat and remove dampness. SSG has a long history of being used both as food and medicine， but it was not enrolled in the Chinese Pharmacopoeia until 2010. Doctors of different dynasties had different views of its processing procedures， and thus the quality of its decoction pieces is inconsistent. This article systematically straightened out the records of SSG in ancient books and modern literature， and summarized and analyzed the processing procedures， chemical constituents， quality analysis and pharmacological effects of SSG. It found that SSG contains proteins， isoflavones， saponins and other components， analytical methods for detecting these components include ultraviolet spectrophotometry （UV）， thin-layer chromatography （TLC）， high performance liquid chromatography （HPLC）， etc. It has effect such as antioxidant， anti-inflammatory， anti-osteoporosis， improvement of menopausal syndrome， treatment of cardiovascular diseases， and processing will change the type and content of its chemical components. Therefore， it is necessary to dig out active constituents of SSG， explore those changes in chemical constituents and pharmacological effect during the period of its primary and subsequent processing， and explore its action mechanism. This paper can provide the theoretical basis for standardized processing procedure， modern quality control and clinical application of SSG.
