Objective To describe an intelligent three-dimensional technique for automatic visualization of the fetal cranial mid-sagittal view to allow for the differential diagnosis of fetal midline anomalies.Methods Two hundred and twenty pregnant women with singleton pregnancies were imaged to display the mid-sagittal view of fetal head using a new 3D program (Smart MSP) developed by our team.Results The mid-sagittal view of the fetal head was successfully visualized in 190 normal cases (95％) and 18 abnormal cases (90％) by Smart MSP program.The total successful rate was 94.5％ (208/220).Conclusions Smart MSP is a novel and feasible method for the automatic visualization of fetal cranial midsagittal plane and may become a potential tool for routinely screening the fetal midline anomalies.

Objective To evaluate the clinical significance of prenatal ultrasonography in diagnosis of retroaortic left innominate vein ( LINV ) . Methods Thirty fetus with retroaortic LINV were involved , including 17 cases of isolated retroaortic LINV and 13 cases of complicated retroaortic LINV . Three-vessel and trachea ( 3VT ) view was focused in the routine second trimester ultrasound screening to observe whether LINV existing or not . And then the transducer was rotated to the fetal sagittal view to assess the relationship between LINV and aortic arch and the convergence of left subclavian vein and left internal jugular vein into the LINV . Results The characteristic feature of retroaortic LINV was the LINV converge into right superior vena cava ( SVC) under the aortic arch ,not above the aortic arch . The most important plane to detect the retroaortic LINV was the 3VT view ,which revealed the abnormal vein lying to the left of pulmonary artery . The abnormal vein then could be traced and revealed its connection with the right SVC beneath the aortic arch on the transverse plane inferior to the 3VT view and on the fetal sagittal plane . Conclusions The whole course of retroaortic LINV can be revealed by ultrasound prenatally ,which can not only account for the abnormal vein to the left of pulmonary artery on 3VT view ,but also play an important role in surgery decision and future cardiac intervention treatment .

Pulmonary drug delivery has become a research focus in recent years, while the action between particles and pulmonary macrophages after particles transportation to lung tissue was paid little attention. Therapeutic efficacy can be enhanced by regulating the particles uptake action of pulmonary macrophages according to different diseases. Referring to a lot of articles, the relationship between common diseases and macrophages was reviewed and the influencing factors in the particles uptake of alveolar macrophages were sum-marized. The review laid foundation for the development of preparations and clinical application of pulmonary drug delivery systems.

Objective:To explore the mechanism of Kechuan'an Oral Liquid in treating asthma based on network pharmacology; To carry out experimental verification.Methods:The effective components and targets of Kechuan'an Oral Liquid were obtained through TCMSP and literature search. The related targets of asthma were screened by GEO database, and the intersection targets of drug and disease were selected. The PPI network was constructed by STRING database, and the GO function and KEGG pathway were enriched and analyzed for key targets by DAVID database. The rats were divided into blank control group, model group and Kechuan'an Oral Liquid group according to the method of random number table. Kechuan'an Oral Liquid group received Kechuan'an Oral Liquid 12.34 ml/kg for gavage, and blank control group and model group were perfused with distilled water of the same volume for gavage, once a day for 3 days. The asthma model of rats was prepared by atomizing the mixture of acetylcholine chloride and histamine phosphate, and HE staining was used to observe the pathological changes of lung tissue; Western blot was used to detect the protein expressions of IL-6, TLR4, MyD88 and TAK1, and the network pharmacological prediction results were verified.Results:A total of 153 active components, 1 896 targets and 2 982 differentially expressed genes of Kechuan'an Oral Liquid were screened out, and 25 intersection targets of drugs and diseases were obtained. The enrichment results showed that toll-like receptor signaling pathway, TNF signaling pathway and Nod-like receptor signaling pathway were the main mechanisms of immune inflammation. Compared with the control group, the lung tissue of rats in the model group showed morphological changes such as thickening of air duct wall and infiltration of inflammatory cells, which were significantly improved in the Kechuan'an Oral Liquid group. Compared with the control group, the expressions of IL-6, TLR4, MyD88 and TAK1 in the model group significantly increased ( P<0.01), and compared with model group, the expressions of IL-6, TLR4, MyD88 and TAK1 in Kechuan'an Oral Liquid group significantly decreased ( P<0.05 or P<0.01). Conclusion:Kechuan'an Oral Liquid can inhibit toll-like receptor signaling pathway and mediate anti-inflammatory effect to treat asthma.

Objective To evaluate the changes in the expression of c-fos protein in the spinal cord in a rat model of oxycodone dependence or withdrawal response.Methods Thirty SPF adult male Sprague-Dawley rats,aged 6-8 weeks,weighing 180-220 g,were divided into 3 groups (n=10 each) using a random number table method:normal saline group (group NS),oxycodone dependence group (group OD),and oxycodone withdrawal group (group OW).In OD and OW groups,oxycodone was injected subcutaneously in back,5 days in total,with the dose of 2,3,4,5 and 6 mg/kg in turn,3 times a day (8:00/15:00/22:00).The equal volume of normal saline was given instead in group NS.The mechanical paw withdrawal threshold was measured at 3 days before administration and 30 min after the last administration every day.The oxycodone withdrawal was induced by intraperitoneal injection of naloxone 4 mg/kg at 8 h after the last administration of oxycodone on 5th day in group OW.The withdrawal response scores and range of weight changes were recorded within 15 min after giving naloxone or normal saline in NS and OW groups.Spinal cord tissues were collected at 1 h after the last administration on 5th day in group OD and at 1 h after giving normal saline or naloxone on 5th day in NS and OW groups for determination of the expression of c-fos protein by Western blot.Results Compared with group NS,the mechanical paw withdrawal threshold was significantly increased on 1 and 2 days after administration,and the expression of c-fos protein in the spinal cord was up-regulated in OD and OW groups,and withdrawal response scores were significantly increased,and the range of weight change was increased in group OW (P＜0.05).The expression of c-fos protein was significantly down-regulated in group OW as compared with group OD (P＜0.05).Conclusion Oxycodone dependence or withdrawal response may be related to the expression of c-fos protein in the spinal cord of rats,and the expression is up-regulated during oxycodone dependence,while down-regulated during oxycodone withdrawal.

Natural lignocellulosic materials contain cellulose, hemicellulose, and lignin. Cellulose hydrolysis to glucose requires a series of lignocellulases. Recently, the research on the synergistic effect of lignocellulases has become a new research focus. Here, four lignocellulase genes encoding β-glucosidase, endo-1,4-β-glucanase, xylanase and laccase from termite and their endosymbionts were cloned into pETDuet-1 and pRSFDuet-1 and expressed in Escherichia coli. After SDS-PAGE analysis, the corresponding protein bands consistent with the theoretical values were observed and all the proteins showed enzyme activities. We used phosphoric acid swollen cellulose (PASC) as substrate to measure the synergistic effect of crude extracts of co-expressing enzymes and the mixture of single enzyme. The co-expressed enzymes increased the degradation efficiency of PASC by 44% compared with the single enzyme mixture; while the degradation rate increased by 34% and 20%, respectively when using filter paper and corn cob pretreated with phosphoric acid as substrates. The degradation efficiency of the co-expressed enzymes was higher than the total efficiency of the single enzyme mixture.
