Objective To observe the changes of serum sphingosine-1-phosphate (S1P) level in asthmatic patients with different severity of bronchial asthma, and to explore the evaluation value of S1P on the severity of asthma.Methods A prospective observational study was conducted. Fifty-two patients with asthma admitted to Department of Respiratory Medicine of the First Affiliated Hospital of Jiamusi University from November 2015 to January 2017 were enrolled. According to the severity of the disease, the patients were divided into mild, moderate and severe groups. In the same period, 25 healthy subjects were served as healthy control group. All the subjects got the peripheral venous blood collection in the morning fasting, the level of serum S1P was determined by enzyme linked immunosorbent assay (ELISA), the peripheral blood eosinophil (EOS) was counted, and the pulmonary function test was performed. The correlation among the parameters was analyzed by Pearson correlation analysis. Receiver operating characteristic curve (ROC) was plotted, and the value of serum S1P on evaluating the severity of asthma was analyzed.Results Fifty-two asthma patients were enrolled, including 17 patients of the mild, 19 of the moderate, and 16 of the severe. Compared with the healthy control group, serum S1P level and peripheral blood EOS in different degree asthma groups were significantly increased, and forced expiratory volume in 1 second (FEV1) was decreased significantly; and with asthma exacerbations, serum S1P levels and peripheral blood EOS were gradually increased [mild, moderate and severe S1P (nmol/L) were 1537.0±120.3, 1980.7±149.5, 2202.2±117.2 (F= 274.624, P= 0.001); EOS (×109/L) were 0.13±0.06, 0.20±0.07, 0.37±0.14 , respectively (F= 44.093,P = 0.001)], and FEV1 was decreased gradually [mild, moderate and severe were 0.89±0.05, 0.63±0.06, 0.42±0.10, respectively (F= 159.756,P = 0.001)]. Correlation analysis showed that there were significant positive correlations between serum S1P level and peripheral blood EOS in patients with mild, moderate and severe asthma (r value was 0.696, 0.746,0.508, allP < 0.05), and negatively correlations with FEV1 were found (r value was -0.761, -0.655, -0.815, all P < 0.01). There was no significant correlation between serum S1P level and EOS, FEV1 in healthy control group (r value was 0.324 and -0.048, bothP> 0.05). ROC curve analysis showed that the area under curve (AUC) of serum S1P for assessing mild, moderate and severe asthma was 0.948, 1.000, 1.000, respectively; when the cut-off of S1P was 1181.8, 1534.2, 1708.6 nmol/L, the sensitivity was 88.2%, 100%, 100%, and the specificity was 88.0%, 100% and 100%, respectively.Conclusions During asthma attack, the serum S1P level was gradually increased with the exacerbation of the disease. Serum S1P level has significant evaluative effect on the severity of asthma.

The nursing key points included:careful observation of the infant condition,exposing the wound,raising the affected limb,wound disinfection,and removing necrotic tissues at the surface skin,applying topical drugs for promoting tissue growth and antibiotics,selecting appropriate dressing to provide suitable environment for tissue regeneration;debridement of inguinal skin,dressing change,assessing pain and providing corresponding care during debridement;infection prevention. After 29 days of treatment and careful nursing care,the skin damage was repaired on the right lower limb,swelling subsided,the necrotic tissues at right inguinal region were completely cleared,granulation tissue was formed,and the infant was discharged smoothly.

Objective: To investigate hard tissue changes produced by maxillary protraction in patients with skeletal Class III malocclusion at different bone age,and to determine the relationship between the effect of maxillary protraction and bone age.Methods:75 subjects of skeletal Class III malocclusion with retruded maxilla were treated by maxillary protraction and rapid maxillary expansion for 6 months.Cephalometric radiographs were taken before and after treatment.The bone age of individual patients was assessed using cephalometric radiographs at the initiation of treatment on the basis of cervical vertebrace maturation indicators(CVMI).Patients were divided into three groups:Prepubertal growth peak group (CVMI Ⅰ-Ⅱ,8.2-11.3 years old), pubertal growth peak group (CVMI Ⅲ,10.2-12.3 yeasr old), and postpubertal growth peak group (CVMI Ⅳ-Ⅵ,11.5-14.5 years old).Results:(1)There was no difference in the maxillary advancement after maxillary protraction between the prepubertal growth peak and the pubertal growth peak groups;(2) in the postpubertal growth peak group, there was a decrease in maxillary skeletal advancement, whereas the dentoalveolar advancement was increased; (3) the posteroinferior rotation of mandible, the increase of lower facial height, and the eruption of maxillary molars showed no correlation with bone age.Conclusion:The importance of performing a biologic evaluation of bone age in the diagnosis and treatment planning of skeletal Class III malocclusions in individual patients must be emphasized.

Objective To explore the clinical values of combined detection of serum CA125, CA72-4 and HE4 levels in the early diagnosis of ovarian cancer. Methods The serum levels of CA125, CA72-4 and HE4 in 111 patients with ovarian cancer, 130 patients with benign ovarian disease and 90 healthy female controls were measured by electrochemical luminescence immunoassay (ECLIA) and enzyme-linked immunosorbent assay (ELISA) methods. The diagnostic values of the three markers were analyzed separately and combinedly in ovarian cancer. Results The serum levels of CA125, CA72-4 and HE4 of ovarian cancer patients were significantly higher than those of benign ovarian disease patients and healthy controls(Ps ＜ 0. 01). The positive expression rate of HE4(63.5%) in patients with stage Ⅰ ovarian cancer was significantly higher than that of CA125(55. 8%) and CA72-4 (42. 6%)(Ps ＜ 0. 05) . The combined detection of the three markers may improve the overall accuracy of the early diagnosis of ovarian cancer to 75.8%. The diagnostic sensitivity of serum CA125 was relatively higher in serous cystadenocarcinoma, endometrioid carcinoma and poorly differentiated adenocarcinoma; the diagnostic sensitivity of serum CA72-4 was relatively higher in mucinous cystadenocarcinoma and endometrioid carcinoma; the diagnostic sensitivity of serum HE4 was relatively higher in serous cystadenocarcinoma and endometrioid carcinoma. Conclusion CA125 can serve as the first choice of tumor maker in the diagnosis of ovarian cancer, and the combined detection of serum levels of CA125, CA72-4 and HE4 may increase the diagnostic sensitivity of stage Ⅰ ovarian cancer.

ObjectiveTo evaluate the parenteral nutrition formula's character of all-in-one-mixed preparation and pre-mixed preparation applied for hospitalized patients in China.MethodsWe collected parenteral nutrition (PN) prescriptions in hospitalized patients with various diseases at dispensing centers of 6 hospitals in different areas of China. Statistic analysis was made by nutrients application, total liquid, nonprotein calories, total nitrogen, ratio of non-protein calories and total nitrogen, and ratio of glucose and fat. A comparison was made between all-in-one-mixed and pre-mixed preparation as to all the indices.Results The nutrients supply in all-in-one-mixed PN preparation, as well as in the pre-mixed PN preparations of 3 different energy degrees can meet the basic nutrition requirements of most patients. The total nitrogen supply in all-in-one-mixed PN prescriptions meets nutrition requirements in most patients, but the ratio of non-protein calories and total nitrogen[( 180-250) : 1]and the ratio of glucose and fat (0. 56-1.26)were significantly different from what a doctor would recommend[( 100-150) : 1, 1.0]. While the ratios in the pre-mixed PN preparation on 3 different energy degrees are more consistent with recommeded values,which are at 167 and 0. 8 respectively.ConclusionsAll-in-one-mixed and pre-mixed PN preparation have their own individual advantages and limits, and both of them can meet the requirements of most hospitalized patients. More attention should be paid to the nutrients proportion when doctors prescribe all-in-one-mixed PN preparations.

Diffuse large B-cell lymphoma (DLBCL) is characterized by heterogeneity with respect to morphology, immune phenotype, molecular pathogenesis, clinical presentation and prognosis. With the development of genome and transcriptome sequencing, DLBCL was classified as four subtypes (EZB, BN2, MCD, and N1) or five subtypes (C1-C5). The new molecular pathological typing has a deeper understanding of DLBCL from the levels of genes and molecules which makes the judgment of prognosis more accurate and specific, and it is conducive to the clinical screening of more accurate targeted therapy.

Objective To investigate the therapeutic effect of exosomes extracted from human adipose-derived mesenchymal stem cells(hAMSCs) on traumatic brain injury (TBI) and its possible mechanism.Methods Mesenchymal stem cells(MSCs) were isolated from healthy human adipose tissue and the exosomes were extracted by ultrafiltration.Rats were divided into four groups: sham group, PBS control group, MSCs treatment group and exosomes treatment group.24 h After TBI, the treatment group was locally injected along the lesion area, 30 μL of PBS, 2×105 MSC, 25 μg protein of exosomes respectively, the total volume was 30 μL.We performed the Modified Neurological Severity Score(mNSS) and the forelimb Foot-Fault Test in all rats before injury and at 1, 3, 7, 10, 13, 16, 21 and 30 days after TBI.The rats were sacrificed at 3 and 7 days after TBI respectively,total RNA was extracted from rat brain tissue.The expression of TNF-α and IL-1β were detected by quantitative PCR.The rats were also killed at 30 days after TBI for testing the neuronal apoptosis in lesion area by tunel-neun double imm-unofluorescence.Results Exosomes treatment significantly promotes the recovery of neurological deficits caused by TBI,and the therapeutic effect is similar to MSCs, its possible mechanism may be the inhibition of the acute inflammation and the reducing of the neurons apoptosis after TBI.Conclusions Exosomes extracted from human adipose-derived mesenchymal stem cellshas promoted neurological functionrecovery after traumatic brain injury, which will provide a new and safer TBI treatment for clinical practice.

The purpose of this paper is to clarify the structure-activity relationship of anti-tumor activity of diosgenin derivatives in vitro. Study has found that diosgenin can inhibit the reproduction of tumor cells by inducing apoptosis and the main target spot of this effect is Bcl-2. Based on the characteristics of pharmacophoric points' of the three-dimensional pharmacophore for Bcl-2 inhibitors, we have docked lots of diosgenin derivatives with Bcl-2, then synthesized 31 compounds of them, finally assessed the anti-tumor activity of the diosgenin derivatives in vitro against A375, A549, HepG-2 and K562. Preliminary studies of SAR have indicated that the aliphatic esters, and aromatic esters of diosgenin without F ring have no anti-tumor activity in vitro. The triazole bromides of diosgenin all achieve fairly good anti-tumor activity in vitro, and those with larger hydrophobic group have the better activity. The stronger is the hydrogen bonding interaction and dipole-dipole interaction of the heterocyclic of diosgenin and diosgenin without F ring and the acid ester of diosgenin without F ring, the better is the activity of derivatives.
