Objective To find a grading method for assisting in evaluating hypoxia degree of patients with pulmonary heart disease non-invasively. Methods To design a quantitative method to score degree of hypoxia of 67 patients with pulmonary heart disease by using acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) as a frame and to make comparative analysis between the grading result and artery blood gas to find the correlation. Results There was a negative correlation between evaluation mark and pH、PaO2、SaO2 and a positive correlation between the evaluation mark and PaCO2, according to statistics. Conclusions Although the grading table of hypoxia evaluation can not substitute blood gas analysis, acting as a non-invasive method to assist in evaluating the hypoxia degree of patients with pulmonary heart disease, it can not only relieve patients' repeated punctuation pain, but also achieve the goal of estimating hypoxia.Consequently the non-invasive method to evaluate hypoxia is of clinical value.

Objective To investigate the levels of peripheral blood plasma M-ficolin/L-ficolin and their correlation with clinical indexes in patients with rheumatoid arthritis (RA).Methods M-ficolin/L-ficolin was detected in the plasma of 61 RA patients who were grouped according to the disease activity and 18 healthy controls by enzyme-linked immunosorbent assay (ELISA).The relationships between the levels of M-ficolin/L-ficolin and laboratory parameters,disease activity were investigated in RA patients.Statistical analysis were performed by t-test,one-way analysis of variance (ANOVA),rank-sum test,correlation analysis was carried out with Pearson/ Spearman rank correlation test.Results ① M-ficolin levels in 61 RA patients were [M (QR) 39 (24) ng/ml] significantly higher than healthy controls (14±4) ng/ml (Z=-5.72,P＜0.05).L-ficolin levels in 61 RA patients were (1.7±0.6) μg/ml obviously higher than healthy controls (1.3±0.5) μg/ml (t=2.55,P=0.013).② The M-ficolin levels of 61 RA patients in low,mediate,high disease activity group were (21±5) ng/ml,[M(QR) 35(13) ng/ml),[M(QR) 50(25) ng/ml].There was significant difference among the three groups (P＜0.01).The L-ficolin levels of 61 RA patients in low、mediate,high disease activity group were (1.2±0.5) μg/ml,(1.7±0.4) μg/ml and (2.2±0.6) μg/ml.There was significant difference among the three groups (P＜0.05).(M-ficolin levels were positively correlated with disease activity score (DAS)28,erythrocyte sedimentation rate (ESR),C reactive protein (CRP),rheumatoid factor (RF),white blood cell (WBC),Note Express User Tool (NEUT),MONO,blood platelet (PLT) (r=0.830,0.692,0.725,0.667,0.388,0.397,0.338,0.476,P＜0.05),L-ficolin levels were positively correlated with DAS28,ESR,CRP,RF,WBC,NEUT,MONO,PLT (r=0.653,0.593,0.630,0.468,0.254,0.302,0.312,0.340,P＜0.05).Conclusion M-ficolin/L-ficolin levels increase in RA patients and correlate with disease activity,which suggests that the complement system may play an important role in the pathogenesis of rheumatoid arthritis.

Objective: To investigate the role of host derived matrix metalloproteinases (MMPs) in the pathogenesis of pulpitis. Methods:The expressions of MMP-2 and MMP-9 were examined by immunohistochemical method and the activity of MMP-2 and MMP-9 were measured by gelatin zymography in 20 clinically healthy and 20 inflamed human dental pulps of extracted mandibular 3rd molars.Results:In clinically healthy and inflamed human pulps both MMP-2 and MMP-9 were expressed in odontoblasts and fibroblasts. The pro-MMP-9 was detectable in both inflamed and healthy pulps. The level of pro-MMP-9 was higher in inflamed pulps than that in the healthy(P0.05).Pro-MMP-2 and active MMP-2 were not detectable in the pulps of the two groups. Conclusion:MMP-9 may involve in the pathogenesis of pulpitis.

Objective: To investigate glucolipid metabolism and sex hormone levels among female children with precocious puberty, so as to provide insights into the illustration of pathogenesis of precocious puberty. Methods: A total of 110 female children with precocious puberty treated in Huzhou Maternity & Child Health Care Hospital during the period from May 2019 through May 2021 were enrolled and assigned into the idiopathic central precocious puberty (ICPP) group and the premature thelarche alone (PT) group according to the results of gonadotropin-releasing hormone stimulation tests. The follicle stimulating hormone (FSH), luteinizing hormone (LH), progesterone (P), estradiol (E2), testosterone (T), prolactin (PRL), fasting insulin (FINS), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), apolipoprotein B (ApoB) andlipoprotein-a [Lp (a)] levels were detected and compared in children between the ICPP and PT groups. Results: There were 70 cases in the ICCP group, with a mean age of (7.62±1.13) years and a mean body mass index (BMI) of (16.30±2.21) kg/m2 and 40 cases in the PT group, with a mean age of (7.42±1.04) years and a mean BMI of (16.70±2.10) kg/m2 (both P>0.05). The FSH [(3.58±0.80) vs. (2.22±0.75) IU/L], LH [(1.40±0.28) vs. (0.25±0.12) IU/L], P [(0.29±0.12) vs. (0.18±0.08) ng/mL], E2 [(23.28±4.23) vs. (15.54±2.75) pg/mL] and PRL [(8.56±1.93) vs. (6.54±1.50) ng/mL], FINS [(13.24±2.54) vs. (11.10±2.49) U/L], TG [(1.36±0.17) vs. (1.21±0.27) mmol/L], LDL-C [(3.10±0.44) vs. (2.81±0.60) mmol/L], ApoB [(0.78±0.19) vs. (0.71±0.14) g/L] and Lp (a) levels [(252.45±52.10) vs. (202.60±41.28) mg/L] were significantly higher in the ICPP group than in the PT group (all P<0.05). Conclusion The levels of sex hormones and glucolipid metabolism parameters are significantly higher among female children with ICPP than among those with PT.

During ischemia, the intracellular acidosis stimulates the Na +/H + exchanger. The increase in intracellular sodium secondary to increased Na +/H + exchange is reversed through exchange for calcium, resulting in calcium overload of the cells and producing cell injury and necrosis. NHE1 inhibitors exert a protective effect on myocardium subject to ischemia and reperfusion via reduction of Na +/H + exchange, attenuation of intracellular calcium accumulation and other mechanisms.

Current research suggests that SLC5A8 is a new candidate tumor-suppressor gene whose expression is reduced or deficient in human thyroid cancer,esophageal cancer,gastric cancer,colon cancer and acute myeloid leukemia.The gene is in human chromosomes 12q13-23,and encoding proteins that belongs to the members of the family of sodium/glucose transporters.It is sodium-coupled carrier that transfer short chain fatty acid,lactic acid,nicotinic acid and iodide.The exon 1 of GPG island methylation and histone acetylation can make SLC5A8 gene express silenced and promote the occurrence of tumor.of all transporter substrates of SLC5A8 expresses,butyrate,propionate and pyruvate function as histone deacetylase inhibitors and can be mediated apoptosis of many kinds of tumor cells,which may be the mechanism of inhibiting tumor.
