Beware of the "high functioning trap" - excessive status expectations in patients with bipolar depression / 四川精神卫生

Maintaining long-term stability of patient's condition is crucial in the treatment for bipolar disorder， while accurately assessing the patient's disease status is important and challenging in maintaining treatment. Excessive status expectation is common in patients with bipolar depression， which would warp the patient's perception of his or her own disease status and， thus， ultimately interfere with clinical decisions. Heightened vigilance should be given to such phenomenon. This paper explores the phenomenon and potential mechanisms of excessive status expectation in patients with bipolar disorder， providing ideas for related diagnosis， treatment and research. ［Funded by Jiangsu Provincial Science and Technology PProject （number， BE2015609）］

ObjectiveTo investigate the protective effect of the extract of Liuwei Dihuangwan （LW） on mitochondrial damage in the Alzheimer's disease （AD） model of Caenorhabditis elegans （C. elegans）. MethodC. elegans transfected with human β-amyloid protein （Aβ） 1-42 gene was used as an AD model. The rats were divided into blank group， model group， metformin group （50 mmol·L-1）， and low， medium， and high dose （1.04， 2.08， 4.16 g·kg-1） LW groups. Behavioral methods were used to observe the sensitivity of 5-hydroxytryptamine （5-HT） in nematodes. Western blot was used to detect the expression of Aβ in nematodes. Total ATP content in nematodes was detected by the adenine nucleoside triphosphate （ATP） kit， and mitochondrial membrane potential was detected by the JC-1 method. In addition， the mRNA expression of Aβ expression gene （Amy-1）， superoxide dismutase-1 （SOD-1）， mitochondrial transcription factor A homologous gene-5 （HMG-5）， mitochondrial power-associated protein 1 （DRP1）， and mitochondrial mitoprotein 1 （FIS1） was detected by real-time fluorescence quantitative polymerase chain reaction （RT-PCR）. ResultThe extract of LW could reduce the hypersensitivity of the AD model of nematodes to exogenous 5-HT （P<0.05） and delay the AD-like pathological characteristics of hypersensitivity to exogenous 5-HT caused by toxicity from overexpression of Aβ in neurons of the AD model of nematodes. Compared with the blank group， in the model group， the mRNA expression of Aβ protein and Amy-1 increased （P<0.01）， and the mRNA expression of SOD-1 and HMG-5 decreased （P<0.01）. The mRNA expression of DRP1 and FIS1 increased （P<0.01）， and the level of mitochondrial membrane potential decreased （P<0.05）. The content of ATP decreased （P<0.01）. Compared with the model group， in the positive medicine group and medium and high dose LW groups， the mRNA expression of Aβ protein and Amy-1 decreased （P<0.05，P<0.01）， and the mRNA expression of SOD-1 and HMG-5 increased （P<0.01）. The mRNA expression of DRP1 decreased （P<0.05，P<0.01）， and that of FIS1 decreased （P<0.01）. The level of mitochondrial membrane potential increased （P<0.01）， and the content of ATP increased （P<0.05，P<0.01）. ConclusionThe extract of LW may enhance the antioxidant ability of mitochondria， protect mitochondrial DNA， reduce the fragmentation of mitochondrial division， repair the damaged mitochondria， adjust the mitochondrial membrane potential， restore the level of neuronal ATP， and reduce the neuronal damage caused by Aβ deposition.

Changes of HER2 low expression status in primary and recurrent/metastatic breast cancer / 中华病理学杂志

Objective: To investigate the evolution and clinical significance of HER2 low expression status in HER2 negative patients in primary and recurrent/metastatic breast cancers. Methods: The data and archived sections of 259 breast cancer patients with recurrence/metastasis and HER2-negative primary foci were collected from January 2015 to January 2022 at the Fourth Hospital of Hebei Medical University, and the HER2 status of primary and recurrence/metastasis foci was determined by immunohistochemistry (IHC), among which IHC 2+patients were subject to fluorescence in situ hybridization (FISH). The HER2 status was classified as HER2-0 group; patients with IHC 1+, IHC 2+and no FISH amplification were classified as HER2 low expression group; and patients with IHC 3+, IHC 2+and FISH amplified were classified as HER2-positive group. The changes of HER2 status in patients with HER2 low expression in primary versus recurrent/metastatic breast cancer foci were compared, and their clinicopathologic characteristics and prognosis were analyzed. Results: The overall concordance rate between primary and recurrent/metastatic HER2 status in breast cancer was 60.6% (157/259, κ=0.178). A total of 102 patients (102/259, 39.4%) had inconsistent primary and recurrent/metastatic HER2 status; 37 patients (37/259, 14.3%) had HER2-0 at the primary foci and HER2-low expression at the recurrent/metastatic; and 56 patients (56/259, 21.6%) had HER2-low expression in the primary foci and HER2-0 in the recurrent/metastatic. The recurrent/metastatic foci became low-expressing compared with the recurrent/metastatic foci which remained HER2-0 patients, with longer overall survival time, higher ER and PR positivity, lower Ki-67 positivity index, and lower tumor histological grade; all with statistically significant differences (all P<0.05). In the primary HER2-low group, patients with recurrent/metastatic foci became HER2-0 while those with recurrent/metastatic foci remained low expression; there were no statistically significant differences in clinicopathological features and overall survival time (all P>0.05). Conclusions: Unstable HER2 status in patients with HER2-0 and low expression in primary versus recurrent/metastatic breast cancer foci, and HER2-0 in the primary foci but low HER2 expression status in recurrence/metastasis is associated with favourable prognosis, and testing HER2 status in recurrence/metastasis can provide more treatment options for such patients.

Hippo pathway-manipulating neutrophil-mimic hybrid nanoparticles for cardiac ischemic injury via modulation of local immunity and cardiac regeneration

The promise of regeneration therapy for restoration of damaged myocardium after cardiac ischemic injury relies on targeted delivery of proliferative molecules into cardiomyocytes whose healing benefits are still limited owing to severe immune microenvironment due to local high concentration of proinflammatory cytokines. Optimal therapeutic strategies are therefore in urgent need to both modulate local immunity and deliver proliferative molecules. Here, we addressed this unmet need by developing neutrophil-mimic nanoparticles NM@miR, fabricated by coating hybrid neutrophil membranes with artificial lipids onto mesoporous silica nanoparticles (MSNs) loaded with microRNA-10b. The hybrid membrane could endow nanoparticles with strong capacity to migrate into inflammatory sites and neutralize proinflammatory cytokines and increase the delivery efficiency of microRNA-10b into adult mammalian cardiomyocytes (CMs) by fusing with cell membranes and leading to the release of MSNs-miR into cytosol. Upon NM@miR administration, this nanoparticle could home to the injured myocardium, restore the local immunity, and efficiently deliver microRNA-10b to cardiomyocytes, which could reduce the activation of Hippo-YAP pathway mediated by excessive cytokines and exert the best proliferative effect of miR-10b. This combination therapy could finally improve cardiac function and mitigate ventricular remodeling. Consequently, this work offers a combination strategy of immunity modulation and proliferative molecule delivery to boost cardiac regeneration after injury.

Comparison study of clinical features between persistent hyperplastic primary vitreous and congenital fibrovascular pupillary membrane / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To analyze the similarities and differences of the clinical features between persistent hyperplastic primary vitreous(PHPV)and congenital fibrovascular pupillary membrane(CFPM).METHODS: Retrospectively analyze the ocular biometric parameters, clinical features and morphological changes in children with PHPV(PHPV group)and CFPM(CFPM group)who received surgery at the department of ophthalmology, Xijing Hospital from March 2006 to December 2021.RESULTS: The study included 56 cases(61 eyes)of PHPV and 24 cases(25 eyes)of CFPM. There were no differences on the gender and age of onset between PHPV and CFPM, and both of them were mainly unilaterally affected, with the ratio of 91% and 96%. Children with PHPV and cataract combined with other complications and ocular developmental abnormalities. CFPM was mainly presented different degrees of blockage and morphological abnormalities of pupillary area. In unilateral cases of PHPV and CFPM, the anterior chamber depth(ACD)of affected eyes was smaller than that of the fellow eyes, and in subgroups with age of operation ≤24mo, the axial length(AL)of affected eyes was smaller than that of the fellow eyes(P&#x003C;0.05). The corneal diameter(CD)of the affected eyes in PHPV group was smaller and the intraocular pressure(IOP)was higher than those of the fellow eyes(all P&#x003C;0.05); while there were no significant differences on CD and IOP between affected eyes and the fellow eyes in CFPM group(P&#x0026;#x003E;0.05). The ACD of affected eyes in PHPV group was significantly smaller than that of CFPM group(P&#x003C;0.05). The fibrovascular membrane in PHPV group was located in the posterior part of the lens and vitreous cavity; while the fibrovascular membrane in CFPM group was located between the iris and the anterior capsule of the lens, rarely involving the lens.CONCLUSION: PHPV and CFPM had the similar clinical features, suggesting that they may belong to the different variants of persistent fetal vasculature(PFV). However, PHPV had a wider range of lesions and more complex conditions.

Basic research of meridian-tendon based on fascia: review and prospects / 中国针灸

Meridian-tendon is a central concept in meridian theory of TCM, and its basic research has been increasingly emphasized. While there is no unified understanding of the essence of meridian-tendon, the concept that function of fascia could partially reflect the functions of meridian-tendons has reached consensus in the academic community. This article suggests that under the guidance of meridian-tendon theory, based on previous research foundation of fascia, focusing on adopting fascia research methods, the mechanisms of tender point hyperalgesia and abnormal proliferation related to meridian lesions should be adopted to explain yitong weishu (taking the worst painful sites of muscle spasm as the points), and the mechanisms of meridian intervention efficacy should be adopted to explain yizhi weishu (feelings from patients and acupuncture operators). Furthermore, this article provides an analysis of the future trends in basic research of meridian tendons.

Cloning and expression analysis of wpHSP90 gene from Whitmania pigra at different temperatures / 中国中药杂志

HSP90 is a widely distributed molecular chaperone that participates in a variety of cellular processes and plays an important role in the meiosis of germ cells. However, its role in the gonadal development of hermaphroditic Whitmania pigra is not yet clear. To explore the effect of HSP90 on the germ cell development of Wh. Pigra, this study cloned the wpHSP90 gene, performed bioinformatics analysis, and measured its expression levels. The results showed that the cloned wpHSP90 was 2 592 bp in length, with an open reading frame(ORF) of 2 373 bp, encoding 790 amino acids. Prediction analysis revealed 85 phosphorylation modification sites on serine, threonine, and tyrosine residues of the wpHSP90 protein. Structural domain prediction and multiple sequence alignment results showed that wpHSP90 contained two conserved domains of HSP90 and exhibited the highest homology with Helobdella robusta, with a sequence similarity of 80.72%. RT-qPCR results showed that the relative expression level of wpHSP90 in the gonads of 5-month-old Wh. pigra was positively correlated with temperature within the range of 12 ℃ to 28 ℃. The expression level in the female gonads was significantly higher than in the male gonads and correlated with the trend of germ cell development in the ovaries and testes. In conclusion, wpHSP90 may be involved in regulating the development of germ cells, particularly oocytes, in Wh. pigra. This study provides a reference for further research on the gonadal development mechanism in Wh. pigra.

Mechanism of albiflorin in improvement of Alzheimer's disease based on network pharmacology and in vitro experiments / 中国中药杂志

This study aimed to explore the mechanism of albiflorin in the treatment of Alzheimer's disease(AD) based on network pharmacology, molecular docking, and in vitro experiments. Network pharmacology was used to predict the potential targets and pathways of albiflorin against AD, and molecular docking technology was used to verify the binding affinity of albiflorin to key target proteins. Finally, the AD cell model was induced by Aβ_(25-35) in rat pheochromocytoma(PC12) cells and intervened by albiflorin to validate core targets and pathways. The results of network pharmacological analysis showed that albiflorin acted on key targets such as mitogen-activated protein kinase-1(MAPK1 or ERK2), albumin(ALB), epidermal growth factor receptor(EGFR), caspase-3(CASP3), and sodium-dependent serotonin transporter(SLC6A4), and signaling pathways such as MAPK, cAMP, and cGMP-PKG. The results of molecular docking showed that albiflorin had strong binding affinity to MAPK1(ERK2). In vitro experiments showed that compared with the blank group, the model group showed decreased cell viability, decreased expression level of B-cell lymphoma 2(Bcl-2), increased Bcl-2-associated X protein(Bax), and reduced phosphorylation level of extracellular signal-regulated kinase 1/2(ERK1/2) and the relative expression ratio of p-ERK1/2 to ERK1/2. Compared with the model group, the albiflorin group showed potentiated cell viability, up-regulated expression of Bcl-2, down-regulated Bax, and increased phosphorylation level of ERK1/2 and the relative expression ratio of p-ERK1/2 to ERK1/2. These results suggest that the mechanism of albiflorin against AD may be related to its activation of the MAPK/ERK signaling pathway and its inhibition of neuronal apoptosis.

Serum metabolomics study of Psoraleae Fructus in improving learning and memory ability of APP/PS1 mice / 中国中药杂志

This study aimed to investigate the mechanism of Psoraleae Fructus in improving the learning and memory ability of APP/PS1 mice by serum metabolomics, screen the differential metabolites of Psoraleae Fructus on APP/PS1 mice, and reveal its influence on the metabolic pathway of APP/PS1 mice. Thirty 3-month-old APP/PS1 mice were randomly divided into a model group and a Psoraleae Fructus extract group, and another 15 C57BL/6 mice of the same age were assigned to the blank group. The learning and memory ability of mice was evaluated by the Morris water maze and novel object recognition tests, and metabolomics was used to analyze the metabolites in mouse serum. The results of the Morris water maze test showed that Psoraleae Fructus shortened the escape latency of APP/PS1 mice(P<0.01), and increased the number of platform crossing and residence time in the target quadrant(P<0.01). The results of the novel object recognition test showed that Psoraleae Fructus could improve the novel object recognition index of APP/PS1 mice(P<0.01). Eighteen differential metabolites in serum were screened out by metabolomics, among which the levels of arachidonic acid, tryptophan, and glycerophospholipid decreased after drug administration, while the levels of glutamyltyrosine increased after drug administration. The metabolic pathways involved included arachidonic acid metabolism, glycerophospholipid metabolism, tryptophan metabolism, linoleic acid metabolism, α-linolenic acid metabolism, and glycerolipid metabolism. Therefore, Psoraleae Fructus can improve the learning and memory ability of APP/PS1 mice, and its mechanism may be related to the effects in promoting energy metabolism, reducing oxidative damage, protecting central nervous system, reducing neuroinflammation, and reducing Aβ deposition. This study is expected to provide references for Psoraleae Fructus in the treatment of Alzheimer's disease(AD) and further explain the mechanism of Psoraleae Fructus in the treatment of AD.

A prospective cohort study of long-term fasting blood glucose variability and risk of mortality in patients with type 2 diabetes / 中华流行病学杂志

Objective: To investigate the association between long-term fasting blood glucose (FPG) variability and all-cause mortality in patients with type 2 diabetes. Methods: A total of 7 174 type 2 diabetic patients included in National Basic Public Health Service Program in Changshu of Jiangsu Province were recruited as participants. Long-term glucose variability was assessed using standard deviation (SD), coefficient of variation (CV), average real variability (ARV), and variability independent of the mean (VIM) across FPG measurements at the more than three visits. Death information were mainly obtained from the death registry system in Jiangsu. Then Cox proportional hazards regression models were used to estimate the associations of four variability indicators and all-cause mortality's hazard ratios (HRs) and their 95%CIs. Results: Among 55 058.50 person-years of the follow-up, the mean follow-up time was 7.67 years, and 898 deaths occurred during the follow-up period. After adjustment, compared with T1 group, the Cox regression model showed that HRs of T3 group in SD, CV, ARV and VIM were 1.24 (95%CI: 1.03-1.49), 1.20 (95%CI: 1.01-1.43), 1.28 (95%CI: 1.07-1.55) and 1.20 (95%CI:1.01-1.41), respectively. HRs of per 1 SD higher SD, CV, ARV and VIM were 1.13 (95%CI: 1.06-1.21), 1.08 (95%CI: 1.01-1.15), 1.05 (95%CI: 1.00-1.12) and 1.09 (95%CI: 1.02-1.16) for all-cause mortality, respectively. In the stratified analysis, age, gender, hypoglycemic agent and insulin uses had no effect on the above associations (all P for interaction >0.05). Conclusion: Long-term FPG glycemic variability was positively associated with the risk of all-cause mortality in type 2 diabetes patients.

The distribution of blood pressure and associated factors of the elderly with type 2 diabetes in Jiangsu Province / 中华预防医学杂志

Objective: To investigate the distribution of blood pressure and analyze the associated factors of blood pressure of the elderly with type 2 diabetes in Jiangsu Province. Methods: The elderly over 60 years old participants with type 2 diabetes in the communities of Huai'an City and Changshu City, Jiangsu Province were selected in this study. They were divided into two groups: taking antihypertensive drugs and not taking antihypertensive drugs. The demographic characteristics, such as age and sex, and relevant factors were collected by questionnaire. The systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured by physical examination. The percentile of SBP and DBP in each age group of men and women were described. The kernel density estimation curve was used to show the blood pressure distribution. The trend of blood pressure with age was fitted by locally weighted regression. The logistic regression model was used to analyze relevant factors of blood pressure. Results: A total of 12 949 participants were included in this study, including 7 775 patients in the antihypertensive drug group and 5 174 patients in the group without antihypertensive drugs. The SBP of participants was concentrated at 140-160 mmHg, and their DBP was concentrated at 75-85 mmHg. There were significant differences in the distribution of blood pressure among the subgroups of body mass index (BMI) and rural areas whether taking antihypertensive drugs and not. For participants aged under 80 years old, the SBP showed an increasing trend with age and the DBP showed a decreasing trend with age. Age, BMI ≥24 kg/m2, fasting blood glucose ≥7.0 mmol/L, living in rural areas and no smoking were influencing factors of the elevated SBP; BMI ≥24 kg/m2, male, living in rural areas, no smoking, drinking alcohol and not receiving drug hypoglycemic treatment were influencing factors of the elevated DBP. Conclusion: The SBP of older diabetic adults in Jiangsu Province is at a high level, and the distribution of blood pressure is significantly different between men and women in taking antihypertensive drugs group. The SBP presents a rising trend and the DBP is decreasing at the age of 60-80 years. The blood pressure level of this population are mainly affected by age, BMI, urban and rural areas, smoking.

Periodontal checklists at baseline and 90 d after treatment were recorded to compare differences of the three groups in periodontal probing depth (PD), bleeding index (BI) and attachment level (AL). Enzyme-linked immunosorbent assay (ELSIA) was used to detect the change of tumour necrosis factor-α (TNF-α), interleukin (IL)-1β by collecting the gingival crevicular fluid of the three sets at baseline, 7 d after treatment and 90 d after treatment. @*Results@#There was no statistically significant difference in periodontal clinical examination indexes(PD,BI,AL) and contents of TNF-α and IL-1β in the gingival crevicular fluid between the three groups at baseline (P>0.05). At 7 and 90 d after treatment, all indexes in the three groups were improved compared with those before treatment. The comparison between groups showed that in periodontal pockets with PD≤5 mm, there was no statistically significant difference in the indicators between the three groups. In periodontal pockets with PD≥6 mm, the minocycline hydrochloride group and the bio-antibacterial peptide group had no statistically significant difference in various indicators, but they were all better than the mechanical scaling group.@*Conclusion@#Basic periodontal therapy is an important treatment for stage Ⅲ periodontitis. Minocycline hydrochloride and biological antibacterial peptides are both effective adjuvant drugs for deep periodontal pockets with PD≥6 mm.

Traditional Chinese Medicine Intervenes in Signaling Pathways Associated with CKD-MBD： A Review / 中国实验方剂学杂志

Traditional Chinese medicine （TCM） has certain advantages in the treatment of chronic kidney disease-mineral and bone disorder （CKD-MBD）. In recent years， there have been many studies on the treatment of CKD-MBD by Chinese medicinal compounds and monomers. As revealed by literature retrieval， the research on the mechanism of Chinese medicine in intervening in signaling pathways related to CKD-MBD was mainly based on self-made Chinese medicinal compounds， and the action pathways involved fibroblast growth factor 23/Klotho （FGF23/Klotho） signaling pathway， Wnt/β-catenin signaling pathway， receptor activator of nuclear factor-κB/receptor activator of nuclear factor-κB ligand/osteoprotegerin （RANK/RANKL/OPG） system， and other signaling pathways. TCM can improve calcium and phosphorus metabolism and bone metabolism disorder， and regulate inflammatory reaction， oxidative stress， apoptosis， and autophagy by regulating this series of signaling pathways for the treatment of CKD-MBD. This paper introduced the research results of these signaling pathways and the mechanism of TCM in the treatment of CKD-MBD in order to provide ideas and references for the related research of Chinese medicine in the treatment of CKD-MBD.

In addition, the postoperative length of hospital stay (LOS) and the adverse events that occurred during the intervention period were compared.@*RESULTS@#A total of 107 patients completed the study, 120 patients were included in the analysis. After 3 days of intervention, the pulmonary function, respiratory muscle strength, MBI and HAM-A of all 3 groups improved compared with that before the intervention (P<0.05 or P<0.01). Compared with the control group, pulmonary function and respiratory muscle strength were significantly improved in the CRT and LE groups (P<0.05 or P<0.01). MBI and HAM-A were significantly improved in the LE group compared with the control and CRT groups (P<0.05 or P<0.01). On the 7th day after intervention, the difference was still statistically significant (P<0.01), and was significantly different from that on the 3rd day (P<0.05 or P<0.01). In addition, on the 7th day of intervention, the pulmonary function and respiratory muscle strength in the LE group were significantly improved compared with those in the CRT group (P<0.01). MBI and HAM-A were significantly improved in the CRT group compared with the control group (P<0.01). There were no significant differences in postoperative LOS among the 3 groups (P>0.05). No training-related adverse events occurred during the intervention period.@*CONCLUSIONS@#LE is safe and feasible for improving pulmonary function, respiratory muscle strength, the ability to complete activities of daily living and for relieving anxiety of patients after cardiac surgery (Registration No. ChiCTR2200062964).
