Objective To investigate the expression of lncRNA SNHG8 in placenta accrete(PA)and its effect on trophoblast invasion and migration.Methods qRT-PCR was used to detect the expression of lncRNA SNHG8 in placenta tissue of 30 cases in PA group and 30 cases in control group,and the correlation between lncRNA SNHG8 expression and prenatal ultrasound score of 30 cases in PA group was analyzed.Transwell and scratch assay were used to detect the effect of lncRNA SNHG8 interference on the invasion and migration of human chorionic trophoblast cells(HTR8/SVneo cells),and western blot was used to detect the expression of MMP-2 and MMP-9.The downstream targets of lncRNA SNHG8 were predicted by StarBase software,and the expression of lncRNA SNHG8 was detected in placental tissues of the two groups.Dual luciferase reporter assay was used to detect the targeting relationship between lncRNA SNHG8 and miR-542-3p.Results Compared with that of the control group,the expression of lncRNA SNHG8 was up-regulated in the placenta tissue of the PA group(P<0.05),and it was positively correlated with prenatal ultrasound score.Interference with lncRNA SNHG8 inhibited the invasion and migration of trophoblast cells(P<0.05);the protein expression of MMP-9 and MMP-2 also decreased signifi-cantly(P<0.05).Biological prediction indicates that miR-542-3p had a binding site with lncRNA SNHG8,and miR-542-3p expression was down-regulated in PA placental tissue(P<0.05).Dual luciferase reporter assay confirmed that lncRNA SNHG8 could target miR-542-3p.Compared with si-SNHG8+inhibitor-NC,co-transfection of si-SNHG8 and miR-542-3p inhibitor enhanced the invasion and migration ability of trophoblast cells(P<0.05).Conclusion lncRNA SNHG8 is highly expressed in PA and is related to the severity of PA.LncRNA SNHG8 promotes the invasion and migration of trophoblast by regulating the level of miR-542-3p.The study suggests that lncRNA SNHG8 plays an important role in the invasion and migration of PA trophoblast cells,which is expected to be a clinical diagnostic biomarker and therapeutic target.

Diabetic peripheral neuropathy(DPN)is a common and devastating complication of diabetes,for which effective therapies are currently lacking.Disturbed energy status plays a crucial role in DPN pathogenesis.However,the integrated profile of energy metabolism,especially the central carbohy-drate metabolism,remains unclear in DPN.Here,we developed a metabolomics approach by targeting 56 metabolites using high-performance ion chromatography-tandem mass spectrometry(HPIC-MS/MS)to illustrate the integrative characteristics of central carbohydrate metabolism in patients with DPN and streptozotocin-induced DPN rats.Furthermore,JinMaiTong(JMT),a traditional Chinese medicine(TCM)formula,was found to be effective for DPN,improving the peripheral neurological function and alleviating the neuropathology of DPN rats even after demyelination and axonal degeneration.JMT ameliorated DPN by regulating the aberrant energy balance and mitochondrial functions,including excessive glycolysis restoration,tricarboxylic acid cycle improvement,and increased adenosine triphosphate(ATP)generation.Bioenergetic profile was aberrant in cultured rat Schwann cells under high-glucose conditions,which was remarkably corrected by JMT treatment.In-vivo and in-vitro studies revealed that these effects of JMT were mainly attributed to the activation of adenosine monophosphate(AMP)-activated protein kinase(AMPK)and downstream peroxisome proliferator-activated receptor gamma coactivator 1-alpha(PGC-1α).Our results expand the thera-peutic framework for DPN and suggest the integrative modulation of energy metabolism using TCMs,such as JMT,as an effective strategy for its treatment.

Objective:To evaluate the role of hippocampal β4-Subunit-Containing Nicotinic Acetylcholine Receptors (Chrnb4) in postoperative delirium in aged mice.Methods:Forty-eight SPF male C57BL/6J mice, aged 18 months, weighing 29-35 g, were assigned into 6 groups using a random number table method: tibial fracture group (TF group, n=6), sham operation group (Sham group, n=6), tibial fracture + adipenine group (TA group, n=9), tibial fracture + control vehicle group (TV group, n=9), sham operation + adipenine group (SA group, n=9), and sham operation + control vehicle group (SV group, n=9). The postoperative delirium model was prepared by tibial fracture under sevoflurane anesthesia. Tibial fracture was simulated by implanting a steel pin into the tibia and then clamping it, while sham group only received a longitudinal incision and suture after anesthesia. A microinjection cannula was implanted into the mouse skull at 5 days before developing the model in TA group, TV group, SA group and SV group. Three mice from each group were randomly selected for microelectrode implantation in the hippocampal CA1 area. Starting from 30 min after surgery, adipenine (62.5 nmol/μl) 2 μl was infused into the cerebral ventricle for 7 consecutive days in TA and SA groups, and vehicle (2 μl) was administered instead at a 24-h interval for 7 consecutive days in TV and SV groups. The expression of Chrnb4 mRNA in the hippocampal tissues was detected by real-time quantitative polymerase chain reaction at 24 h after surgery. On the 7th and 8th days after surgery, the open-field test and O-maze experiment were conducted to assess the impulsive-like behavior in TA, TV, SA and SV groups. After the behavioral test, the expression of glial fibrillary acidic protein (GFAP) and vesicular glutamate transporter 1 (Vglut1) in the hippocampal CA1 region was detected by immunofluorescence staining. The local field potentials in the hippocampal CA1 region were recorded during the open field test. Results:The expression of Chrnb4 mRNA in the hippocampal tissues was significantly up-regulated in TF group compared to Sham group ( P<0.05). Compared with TV group, the percentage of central path distance in the open field test and percentage of time spent in the open arms of the O-maze were significantly decreased, the power of β-waves in the CA1 field potentials was decreased, the expression of GFAP and Vglut1 in the hippocampal CA1 region was down-regulated, and the co-staining area of GFAP + and Vglut1 + was decreased in TA group and SV group ( P<0.05). There was no significant difference in each parameter between SA group and SV group ( P>0.05). Conclusions:Hippocampal Chrnb4 may be involved in the mechanism of postoperative delirium in aged mice, and this process may be related to inhibition of neuron excitotoxicity.

Objective:To explore the expression level and clinical significance of serum Hsa_circ_0089761 in patients with cervical cancer.Methods:A total of 107 cervical cancer patients, 80 cervical intraepithelial neoplasia (CIN) patients, and 60 normal control group were selected and analyzed from January 2021 to March 2023 at the Ninth Affiliated People's Hospital of Shanghai Jiao Tong University School of Medicine. We compared the levels of serum Hsa_circ_0089761, squamous cell carcinoma antigen (SCCA), and carcinoembryonic antigen (CEA) among different groups, and analyzed the relationship between the expression level of serum Hsa_circ_0089761 and the clinical and pathological characteristics of cervical cancer. The receiver operating characteristic (ROC) curve was drawn to analyze the diagnostic value of serum Hsa_circ_0089761, SCCA, and CEA levels for cervical cancer. Pearson correlation analysis was used to evaluate the correlation between serum Hsa_circ_0089761 expression levels and SCCA and CEA in cervical cancer patients.Results:The expression levels of serum Hsa_circ_0089761[(2.96±0.95) vs (1.83±0.74), (0.92±0.41)], SCCA[(9.63±1.84)ng/ml vs (2.28±0.65)ng/ml, (1.30±0.27)ng/ml], and CEA[(6.47±2.20)ng/ml vs (1.61±0.57)ng/ml, (1.15±0.12)ng/ml] in the cervical cancer group were significantly higher than those in the CIN group and the control group (all P<0.001), and the serum Hsa_circ_0089761 expression levels in the CIN group were significantly higher than those in the control group ( P<0.001). Cervical cancer patients in stages Ⅲ-Ⅳ, with low differentiation, lymph node metastasis, infiltration depth ≥1/2 of the muscle layer, positive SCCA, and positive CEA had significantly higher levels of serum Hsa_circ_0089761 expression (all P<0.05). The ROC curve analysis showed that the specificity of diagnosing cervical cancer was highest (85.00%) for Hsa_circ_0089761 ≥2.25, and the area under the ROC curve (AUC) for diagnosing cervical cancer in combination with SCCA was highest (0.932, 95% CI: 0.874-0.993), with the highest accuracy (89.30%). The sensitivity of the combination of Hsa_circ_0089761+ SCCA+ CEA in diagnosing cervical cancer was highest (96.26%). The correlation analysis results showed that the serum Hsa_circ_0089761 expression levels in cervical cancer patients were positively correlated with SCCA ( r=0.775, P<0.001) and CEA ( r=0.613, P<0.001). Conclusions:The expression level of serum Hsa_circ_0089761 in cervical cancer patients is significantly increased, which is related to clinical and pathological characteristics. The combination of Hsa_circ_0089761 and SCCA detection has high value in the diagnosis of cervical cancer.

Objective:To analyze the experiences and practice in the reform of public hospital salary system in Sichuan province, summarize the typical modes of such reform in the province, and provide references for further reform.Methods:As of October 29, 2021, the research group received 77 sets of typical experience materials submitted by the health commissions and public hospitals in Sichuan province on enforcing the reform of the public hospital salary system. The analysis framework was based on the five main elements proposed in the Guidance to Deepening the Reform of the Salary System of Public Hospitals for the purpose of furthering the reform. These five elements refer to " reasonably determining the level of salary in public hospitals" " fully implementing the autonomy of internal distribution in public hospitals " " establishing and improving the incentive and restraint mechanism for the remuneration of public hospital leaders" " improving the assessment and evaluation mechanism oriented to public welfare" and " funding sources ". A quantitative analysis was made on the typical experience materials using the social network analysis method, while a qualitative analysis was made on the typical experience materials using the content analysis method. Results:The results of social network analysis showed that the network density was 0.272; the highest point centrality was " fully implement the autonomy of internal distribution in public hospitals" (0.935), and the highest intermediary centrality was " improving the assessment and evaluation mechanism oriented to public welfare" (0.870), while the closeness to centrality of " establishing and improving the incentive and constraint mechanism for the salary of public hospital leaders" (0.434) and " funding sources" (0.421) were relatively low. The results of content analysis showed that the ones with higher frequency among all the typical experience materials were " fully implementing the autonomy of internal distribution of hospitals" (72 times) and " improving the assessment and evaluation mechanism oriented to public welfare" (67 times), while the ones with lower frequency were " establishing and improving the salary incentive and constraint mechanism for public hospital leaders" (17 times) and " funding sources" (14 times). In terms of unity and synergy, the typical models of public hospital salary system reform in the province could be categorized as the fine standard mode, the fair value mode, the autonomous synergy mode and the circular symbiosis mode.Conclusions:Deepening the reform of the salary system of public hospitals should unify the standards and improve the fair and refined assessment and evaluation mechanism; explore various forms of distribution and build an internal autonomous and synergistic incentive mechanism; pay attention to the weak remuneration incentive mechanism for hospital leaders and the problem of a relatively single source of funding.

Research of healthy life expectancy (HLE) is needed in an aging society and by the Healthy China Initiative. However, China has not developed the HLE policy goal nor published HLE values. Therefore, it is essential to construct the HLE indicator system to guide HLE estimation and research. Based on the definition of health from the WHO and the concepts from the United Nations Sustainable Development Goal, One Health and Active Health, we systematically reviewed the existing international HLE indicators, and initially proposed a novel multi-dimensional HLE conceptual framework and indicator structure according to international function, disability and health classifications and international disease classification framework of WHO. The conceptual framework includes five dimensions-physical, mental, behavioral, social, and environmental health, and the comprehensive indicator for disability-disability index is added. Furthermore, we proposed the HLE indicator structure, including behavioral factors, physiological and pathological reasons, impairment, functional limitation, disability and death. Then we discussed the approaches, types of data, and potential data sources for such research. The results of this study would facilitate HLE research and contribute to the aging society and Healthy China Initiative.
