ObjectiveTo explore the possible mechanisms of Shujin Jiannao Formula （舒筋健脑方） for cerebral palsy. MethodsThirty 7-day-old SD rats were randomly divided into normal group， model group， and Shujin Jiannao Formula group， with 10 rats in each group. The model group and Shujin Jiannao Formula group established a cerebral palsy model by the classic Rice-Vannucci method. After successful modeling， rats in Shujin Jiannao Formula group were given Shujin Jiannao Formula 16 g/（kg·d） by gavage， while the normal group and model group were given normal saline 10 ml/（kg·d） by gavage once a day. After one week of intervention， the rats' body weight was measured， and Zea-Longa scores， the righting reflex test， and the hindlimb suspension test were conducted for assessment； hematoxylin-eosin （HE） staining and Nissl staining were used to observe pathological changes in brain tissue， and the number of Nissl-positive neurons was counted； enzyme-linked immunosorbent assay （ELISA） was employed to measure levels of inflammatory cytokines in the brain tissue， specifically interleukin-1β （IL-1β） and tumor necrosis factor-α （TNF-α）； immunofluorescence was used to detect the expression levels of neurofilament protein 200 （NF200） and myelin basic protein （MBP） in brain tissue； Western Blot analysis was conducted to determine the protein levels of phosphoinositide 3-kinase （PI3K）， protein kinase B （Akt/PKB/Rac）， and mammalian target of rapamycin （mTOR） in brain tissue. ResultsCompared with the normal group， rats in the model group showed significantly higher Zea-Longa scores and lower scores in the hindlimb suspension test （P＜0.01）； pathological findings revealed loose structure in the cerebral cortex， hippocampal atrophy， and neuronal damage in brain tissue. Levels of IL-1β and TNF-α elevated， and the number of Nissl-stained positive neurons in the cortex and hippocampal CA1 region reduced， and immunofluorescence intensity of NF200 and MBP， as well as protein expression levels of PI3K and mTOR， significantly decreased （P＜0.05 or P＜0.01）. Compared with the model group， rats in Shujin Jiannao Formula group showed decreased Zea-Longa scores and increased hindlimb suspension test scores （P＜0.05）； pathological damage in brain tissue alleviated， levels of IL-1β and TNF-α reduced， the number of Nissl-stained positive neurons in the cortex and hippocampal CA1 region increased， and the immunofluorescence intensity of NF200 and MBP， as well as the protein levels of PI3K and mTOR， significantly elevated （P＜0.05 or P＜0.01）. There were no statistically significant differences among the groups in body weight， body-turning time， or AKT protein levels in brain tissue （P＞0.05）. ConclusionShujin Jiannao Formula can improve the neurological function of rats with cerebral palsy， exert neurorestorative effects， and its mechanism of action may be related to the reduction of inflammatory response in brain tissue and the activation of the PI3K/AKT/mTOR signaling pathway.

The biological samples of oral genetic diseases and rare diseases are extremely precious. Collecting and preserving these biological samples are helpful to elucidate the mechanisms and improve the level of diagnose and treatment of oral genetic diseases and rare diseases. The standardized construction of biobanks for oral genetic diseases and rare diseases is important for achieving these goals. At present, there is very little information on the construction of these biobanks, and the standards or suggestions for the classification and coding of biological samples from oral and maxillofacial sources, and this is not conducive to the standardization and information construction of biobanks for special oral diseases. This consensus summarizes the background, necessity, principles, and key points of constructing the biobank for oral genetic diseases and rare diseases. On the base of the group standard "Classification and Coding for Human Biomaterial" (GB/T 39768-2021) issued by the National Technical Committee for Standardization of Biological Samples, we suggest 76 new coding numbers for different of biological samples from oral and maxillofacial sources. We hope the consensus may promote the standardization, and smartization on the biobank construction as well as the overall research level of oral genetic diseases and rare diseases in China.

TORCH, which is considered as a series of pathogens, including the Toxoplasma gondii, Rubella virus, Cytomegalovirus or Herpes simplex virus, often infects the pregnant women to induce the the fetus or newborn infection by transplacental infection or exposure to contaminated genital tract secretions at delivery. Increasing evidence have been confirmed that the infection of TORCH may cause the miscarriage, premature birth, malformed fetus, stillbirth, intrauterine growth retardation, neonatal multiple organ dysfunction and other adverse pregnancy outcomes. For most TORCH-infections cases may lacking the effective treatments during pregnancy, and it is important to achieve the effacing monitoring of TORCH infections before and during pregnancy. The laboratory testing of TORCH has the great significance. However, the consensus opinions still need to improve the the standardization of TORCH testing process and the correct interpretation. Based on the characteristics of the TORCH detection method, this article gives a consensus opinion on the standardized detection and clinical application of TORCH from the laboratory perspective according to the characteristics and types of infection of different pathogens.

Objective: To examine whether the long-term resting heart rate (RHR) pattern can predict the risk of cardiovascular and cerebrovascular diseases (CVDs). Methods: This prospective cohort study included 63 040 participants who took part in the health examination in 2006 and one of the health examinations on 2008 or 2010 and were free of myocardial infarction, stroke, arrhythmia, cancer and not treated with β-recepter blocker. The outcomes were the first occurrence of myocardial infarction and stroke during the follow up ended on December 31, 2015. RHRs were measured in 2006, 2008, and 2010. We used latent mixture modeling SAS Proc procedure to identify RHR trajectories. We identified 4 distinct RHR trajectory patterns based on the data derived from 2006 and on the pattern change during 2006 to 2010 (low-stable, moderate-stable, moderate-increasing, elevated-decreasing). Collected the general clinical data of the patients. Cox regression model was used to determine the association between RHR trajectory patterns and the risk of CVDs during follow up. Hazard ratio (HR) with 95% confidence intervals (CI) were calculated using Cox regression modeling. Results: There were statistical significance among the 4 distinct RHR trajectory patterns on the following variables: age, gender, smoking status, drinking status, physical activity, education status, history of use antihypertensive drugs, history of hypertension,history of diabetes, body mass index, triglycerides, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, fasting blood glucose, and the level of high-sensitivity C-reactive protein (all P<0.01). The moderate-increasing pattern experienced the highest risk of developing stroke and CVDs among all 4 patterns. The cumulative incidence of cerebral infarction, cerebral hemorrhage and CVDs in the order of low-stable trajectory, moderate-stable trajectory and moderate-increasing trajectory. The cumulative incidences of cerebral infarction, cerebral hemorrhage and CVDs in elevated-decreasing trajectory group were significantly lower than those in moderate-increasing trajectory group, but higher than those in moderate-stable trajectory group. Compared to the low-stable pattern, adjusted HR was 1.3 (95%CI 1.0-1.6) for the moderate-increasing pattern after adjustment for potential confounders. Conclusion Our study finds that individuals with moderate-increasing RHR trajectory pattern are associated with higher risk of cardiovascular and CVDs.

Objective: To analyze the relationship between inflammatory factors and relevant risk factors in patients of essential hypertension (EH) combining acute coronary syndrome (ACS) with its clinical significance. Methods: Our research included 3 groups: EH group, n=79 patients with standard criteria, EH+ACS group, n=85 and Control group, n=48 normal subjects. Blood levels of lipoprotein-associated phospholipase A2 (Lp-PLA2), tryptase (TPS) and relevant clinical, biochemical parameters were measured; risk factors for cardiovascular disease were examined and the relationship between above parameters, risk factors and ACS occurrence in EH patients was studied by Logistic regression analysis. Results: The OR values were all greater than 1 in fibrinogen (Fbg), high-sensitivity C-reactive protein (hs-CRP), TPS, atherosclerotic plaque, Lp-PLA2 and EH grading. Fbg was the most significant independent risk factor (OR=22.242, 95% CI 6.458-76.609, P<0.0001), the standardized partial regression coefficient b'as absolute value (b') was 1.079 which was the highestone in above 6 variables with the strongest impact for ACS occurrence in EH patients. Conclusion: Fbg, hs-CRP, TPS, atherosclerotic plaque and EH grading were the independent risk factors for ACS occurrence in EH patients; Fbg was the highest risk factor for ACS occurrence with the strongest impact, which provided a new direction for ACS prevention and treatment.

AIM: To investigate the effects of octreotide on metabolism in the A549 cells treated with lipopo-lysaccharides ( LPS).METHODS: The technologies of gas chromatography/mass spectrometry (GC/MS) and liquid chromatography/mass spectrometry (LC/MS) were used to test the metabolism of lung A549 cells subject to different treat-ment with LPS and/or octreotide.The results were visualized and checked by chromatogram, and the corresponding intensi-ty data were analyzed by the principal component analysis(PCA)method.The metabolites with different expression and the underlying interaction network were resolved.RESULTS: The metabolism analysis by LC/MS method indicated that there were different expression levels between different treated groups.Further analysis was carried out by orthogonal projections to latent structures-discriminant analysis (OPLS-DA) and the different expressed metabolites were obtained, which were mainly amino acids and phospholipids.By analyzing with GC/MS method and t-test, the different expressed metabolites were mainly organic acid, saccharides and amino acid metabolite.The interaction network diagram was constructed about the response of A549 cells induced by LPS and/or octreotide, including glycolysis/gluconenogenesis, tryptophan metabo-lism, galactose metabolism, urine cycle and citrate cycle.Fourteen key components were found such as serotonin, indole, threonine, serine, glucose, phenylalanine, lactose, fumarate, 4-hydroxyphenyllactate, aspartate, asparagine, putrescine, proline and succinate.CONCLUSION: In octreotide treated LPS-induced A549 cells, the main metabolites are organic acid, saccharides, amino acids and phospholipids.The interaction network is constructed, including 5 metabolic pathways
and 14 key components.

AIM:To study the morphological changes of cardiac H9c2 cells during the developmental process of fetal rat.METHODS:Embryonic rat heart-derived H9c2 cells were maintained in DMEM supplemented with 10%fetal bovine serum.The H9c2 cells were plated at a density of 6 000 cells/cm and divided into 5 groups:H9c2 cells were trea-ted with 5 mmol/L glucose, 25 mmol/L glucose, 50 mmol/L glucose, Norvasc (25 nmol/L) +25 mmol/L glucose, or Norvasc (25 nmol/L)+50 mmol/L glucose for 48 h.The morphology of H9c2 cells was observed.The cell surface area was measured by Image-Pro Plus 6.1 software.Fluorescence spectrophotometry was used to detect the concentration of in-tracellular calcium ion ( [ Ca2+] i ) in the cardiomyocytes.The concentration of CaN in the cell was measured by ELISA.

Objective To explore the related risk factors of cerebrovascular disease induced cerebral microbleeds and its nursing strategies. Methods A total of 393 patients with acute cerebrovascular disease who were admitted to our hospital from January 2012 to January 2014 were selected. 146 patients who were hospitalized due to non-central ner-vous system disease at the period of time were selected as control group. Baseline data of patients were recorded, and regular MRI T2-weighted imaging were given to all patients. Incidence rate of cerebral microbleeds for patients with different types of cerebrovascular diseases was analyzed. Results Among 393 patients with acute cerebrovascular dis-ease, 206 patients were cerebral microbleeds. Incidence rate was different for different diseases. Incidence rate of hy-pertension was 47.20%, cerebral infarction was 45.98%, diabetes was 44.00%, atrial fibrillation was 50.00%, cerebral hemorrhage was 84.00%, TIA was 25.00%, and leukoencephalopathy was 63.24%. The incidence rate in the control group was 13.70%, except for TIA, the differences between the control group and other groups were statistically signifi-cant (P<0.05). Cerebral microbleeds were taken as dependent variables, and other risk factors were taken as independent variables. Leukoencephalopathy, hypertension, high cholesterol, asymptomatic lacuna cerebral infarction, cerebral bleeding and cerebral infarction were risk factors for cerebral microbleeds, in which low density lipoprotein was a pro-tective factor. 206 patients with cerebral microbleeds were given nursing care. 20 patients recovered and discharged, 129 patients got better, 40 patients were not recovered, 7 patients were transferred to other hospitals, and 10 patients died. The hospitalization time was 1 to 33 days, with an average of (15.3±2.3) days. Conclusion Incidence rate of cere-bral microbleeds for patients with cerebral infarction, cerebral bleeding and leukoencephalopathy is relatively high, and low density lipoprotein is the protective factors for cerebral microbleeds. Hypertension, asymptomatic lacuna cerebral infarction, cerebral bleeding, cerebral infarction, high cholesterol and leukoencephalopathy are risk factors for cerebral microbleeds. Scientific and proper nursing care for patients with cerebral microbleeds is able to significantly improve patients' recovery rate, which is worthy of further clinical promotion and application.

Objective To investigate the effects of dexamethasone on expressions of epithelial neutrophil activating protein-78 (ENA-78) and transforming growth factor- beta 1 (TGF-β1) in neutrophil of asthma rats.Methods Thirty male SD rats were randomly divided into three groups on average, including asthma group, control group and dexamethasone treated group. In this experiment, the rat model of asthma were established by sentization and challenge with ovalbumin. Blood neutrophil were isolated and purified. The expression of ENA-78 was detected by flow cytometry. The expression of TGF-β1 was detected by immunohistochemical method in blood neutrophil and bronchial wall. Results Expression of ENA-78 in blood neutrophil in dexamethasone treated group(71.82 ±8. 87 mean fluorescence intensity)was lower than that in asthma group, but higher than that in control group(all P ＜0. 01). And expressions of TGF-β1 protein in dexamethasone treated group(0. 173 ± 0. 014,0. 202 ± 0. 019 optical density, respectively) was lower than that in asthma group(all P ＜0. 01) ,but higher than that in control group(all P ＜0. 01). There were significant positive correlation between ENA-78 expression at blood neutrophil and numbers of total inflammation cells in bronchoalveolar lavage fluid (n = 29, γ = 0. 762, P ＜ 0. 01). Conclusion The beneficial effect of glucocorticoid(dexamethasone) on airway inflammation in asthma rats could be at least in part due to their direct inhibitory effect on ENA-78 and TGF-β1 protein generation by neutrophil.

Objective To observe the expressions of grouth-related oncogen (GRO)α, epithelial neutrophil activating protein-78 (ENA-78) and neutrophil-activating peptide-2 (NAP-2) of rat asthma. And to investigate the role of neutrophil in the pathogenesis of asthma exacerbation. Methods In this experi-ment, the rat model of asthma were randomly divided into two groups on average, including asthma group and control group. Levels of ENA-78 at blood neutrophil were detected by flow cytometry method. The ex-pressions of GROα protein at bronchial wall and NAP-2 protein at blood neutrophil were detected by immuno-histochemieal method. Results Levels of GROα, ENA-78 and NAP-2 proteins in asthma group [0.138 ±0.009(A value), 97.65±13.99(MFI), 0.198±0.016(A value), respectively]were significantly higher than those in control group[0.077±0.010(A value), 50.79±8.66(MFI), 0.079±0.015(A value), re-spectively], all P < 0.01. Conclusion Levels of GROα, ENA-78 and NAP-2 were increased at rat asth-ma. They may be participate in inflammation of asthma exacerbation. Neutrophil may promote inflammatory cells influxing into airway wall via increasing synthesis of CXC chemotactic factors.
