Objective:To explore the ultrasonic classification in cesarean scared pregnancy (CSP)and its effect on guiding the clinical treatment.Methods:The clinical data of 41 patients with CSP in the Third people's hospital of Chengdu from January 2013 to January 2016 were analyzed retrospectively.Diagnosis was confirmed according to the diagnostic criteria for ultrasound imaging by Godin etal and the history of cesarean section.Patients were divided into type Ⅰ group and type Ⅱ group through measuring the outside uterine muscle layer thickness of pregnant bursa,based on the criteria by Vial et al.Type Ⅰ:MTX intramuscular injection followed by ultrasound guided Dilation and Curettage(D&C)3 days later.Type Ⅱ]:Uterine artery chemo-embolization (UACE)followed by ultrasound guided D&C 2 days later,or lesion resection and repair of the uterus by trans-abdominal or laparoscopic or trans-vaginal operations 2 days later.Results:The outside uterine muscle layer of pregnant bursa in type Ⅱ] was more thinner than that in type Ⅰ (2.1 ± 1.1 mm vs 3.7 ±0.6 mm,P ＜ 0.05).The number of abortion in type Ⅱ was more than that in type Ⅰ (2.8 ± 0.7 vs 1.5 ± 0.6,P ＜ 0.05).There were no statistically significant differences in age,amenorrhea duration and the number of cesarean section (P ＞ 0.05).Patients from two group were treated successfully,and there was no statistical significance about,intraoperative bleeding volume,preoperative serum levels of β-HCG and average recovery time of serum β-HCG(P＞0.05).The average hospital stays and cost in type Ⅰ were less than that in type Ⅱ,with statistical significance (4.7 ± 2.5 vs 8.6 ± 2.7 days,5234.6 ± 1688.8 vs 15668.4 ±4623.4 RMB,P ＜ 0.05).Conclusions:The ultrasonic classification of CSP plays a directive role in making treatment option,with reliabe effect and the good prognosis.UACE as a pretreatment which can control intraoperative bleeding,is an effective method for CSP.For its higher cost,UACE should be selectively used in type Ⅱ[CSP,with cost-effective.MTX intramuscular injection used in type Ⅰ CSP before D&C is reliable and cost-effective.

Objective To explore the clinical characteristics of Mycoplasma pneumoniae pneumonia (MPP) with different imaging changes in children.Methods Hospitalized patients with MPP during September 2012 to August 2013 in Beijing New Century Children's Hospital were retrospectively reviewed.The data including clinical features,laboratory tests,treatment and prognosis were collected.The patients were divided into 3 groups according to the radiological findings,including interstitial infiltration (group 1),intralobular infiltration (group 2) and segmental or larger infiltration (group 3).The clinical data were compared among the 3 groups.Results The percentages of patients in the 3 groups were 18.8％ (36/191 cases) in group 1,39.8％ (76/19 cases) in group 2 and 41.4％ (79/191 cases) in group 3,respectively.In 144 cases of MPP patients older than 3 years old,48.6％ (70/144 cases) were segmental or larger infiltration.The incidence of higher fever,hypoxemia and elevated C-reaction protein and lactate dehydrogenase in group 3 [50.6％ (40/79 cases),87.3％ (69/79 cases),78.5％ (62/79 cases),29.1％ (23/79 cases)] were higher than those in group 1 [5.6％ (2/36 cases),61.1％ (22/36 cases),19.4％ (7/36 cases),0] and group 2 [10.5％ (8/76 cases),67.1％ (51/76 cases),14.5％ (11/76 cases),3.9％ (3/76 cases)],and the differences were significant(all P ＜ 0.01).Patients in group 3 had higher risk of cardiac and/or liver impairment,refractory MPP,and treated by glucocorticoids and bronchoalveolar lavage [41.8 ％ (33/79 cases),29.1％ (23/79 cases),94.9 ％ (75/79 cases),50.6％ (40/79 cases)].The hospital stay was (9.48 ±3.26) d in group 1,(9.24 ±2.97) d in group 2,and (12.09 ±3.01) d in group 3,respectively,and the difference was significant among 3 groups (F =19.348,P =0.005),the hospital stay in group 3 was longer than that in the other 2 groups (t =4.210,5.931,all P =0.000),while there was no difference between group 1 and group 2 (P ＞ 0.05).Patients in group 1 with wheeze were more co-mmon,and were treated by Azithromycin earlier than that in group 3 [(5.08 ± 3.43) d vs.(4.16 ± 2.20) d],the difference was significant(t =2.498,P =0.014),while the incidence of hypoxemia was common than that in group 2 (x2 =3.176,P =0.012).Conclusions MPP patients with segmental or larger infiltration are older than patients in the other groups,and present with severe complications,higher inflammatory factors,longer hospital stay,and higher risk for refractory MPP.Glucocorticoids and bronchoalveolar lavage are usually used in these patients.Patients with interstitial infiltration are prone to manifest with wheeze and hypoxemia,and its diagnosis and treatment by Azithromycin are usually delayed.Therefore,pediatrician should pay more attention to MPP patients with different imaging changes,in order to diagnose and treat the patients timely.

Objective To explore the changes and significances of serum leptin and interleukin-1?(IL-1?)before and after treatment with risperidone in children with schizophrenics.Methods Thirty-one cases with first-episode children with schizophrenia were chosen in patient group.Their body weight and height were measured before and 8 weeks after treatment with risperidone to calculate the body mass index(BMI),and their fasting serum leptin and IL-1? were assayed radio-immunity method.Thirty-one healthy controls were measured at the same time.Results BMI and the level of serum leptin in patients of post-treatment increased significantly compared with those of pre-treatment(all P

Objective To investigate demography of sensory tricks in cervical dystonia (CD),and to discuss the relationship between sensory tricks and the function of sensorimotor integration of cerebral cortex,meanwhile to explore potential worthiness using sensory tricks in the management of CD.Methods We recruited 75 patients (23 male,52 female,male female ratio:1:2.26;aged 19-72 years,mean (42.45 ± 13.09) years) admitted to the Dystonia Clinic Center of the First Affiliated Hospital of Dalian Medical University from March 2016 to April 2013.Standardized questionnaire on sensory tricks was used to investigate the sensory tricks first recognized in 75 patients retrospectively.Median nerve somatosensory evoked potential via multipoint recording was measured in 43 CD patients who manifested as simple rotation of neck.Bilateral amplitudes of P22/N30 derived from F (3,4) were compared.Results Frequency of sensory tricks in CD was 85.53％ (64/75) in our research.As disease progressed,the type of sensory tricks used by patients may transform from one to another or even disappear.No statistically significant differences were found in ages among patients using classic sensory tricks,forcible tricks and patients without sensory tricks,whereas the complexity of the disease showed increased tendency among the three groups.Bilateral P22/N30 amplitudes of patients with classic sensory tricks showed no significant differences.P22/N30 amplitudes contralateral to the head turn were significantly higher than ipsilateral in patients using forcible tricks ((3.16 ± 1.71) μV vs (2.47 ± 1.28) μV,t =2.243,P=0.038) and patients without sensory tricks ((3.62 ±1.58) μV vs (2.73 ±1.14) μV,t=2.893,P=0.023).Tsui scores among patients using classic sensory tricks (9.36 ± 3.52) and forcible tricks (12.67 ± 5.00) or patients without sensory tricks (15.18 ± 4.07) had statistically significant differences (classic sensory tricks vs forcible tricks,t =-3.020,P =0.004;classic sensory tricks vs patients without sensory tricks,t =-4.452,P =0.000).Conclusions Types of sensory tricks used by patients are associated with severity of the disease.Different types of sensory tricks may reflect status of adaptive compensatory mechanism of the cerebral cortex.

We wished to assess the role of chlamydia micro virus capsid protein Vp3 in recombinant molecules, chart its molecular evolution, screen the wild-type strain, and reveal its value in clinical research. Using a protein BLAST multiple-alignment program, we compared various strains of Chlamydia micro virus capsid protein Vp3 sequences. Using a "distance tree" of those results, we created a phylogenetic tree. We applied the Karplus-Schulz method of flexible-region analyses for highly conserved alignments of amino-acid sequences. Gamier-Robson and Chou-Fasman methods were employed to analyze two-level structures of sequences. The Emini method was used for analyses of the accessibility of surface epitopes. Studies of hydrophilic proteins were undertaken using Kyte-Doolittle and Hopp-Woods methods. Analyses of antigen epitopes helped to reveal the antigen index using the Jameson-Wolf method. All sequences in the six strains of chlamydia micro virus capsid protein Vp3 were highly conserved, with the main differences being between Vp3 protein in Chp1 and the other five strains of the micro virus. The viral strain of Vp3 protein was based mainly on micro-alpha helix structures, and multiple epitopes were noted in highly conserved regions. Vp3 protein was highly conserved structurally, and was an important protein of the chlamydiaphage capsid. Vp3 protein has a complicated molecular structure, highly conserved regions with strong immunogenicity, and has considerable research value.

To investigate the morphogenetic process of human adenovirus type 41 (HAdV-41), 293TE cells were infected with purified wild-type HAdV-41, and ultrathin sections of infected cells were prepared and observed under a transmission electron microscope. Results showed that HAdV-41 entered host cells mainly through three ways: non-clathrin-coated pit, clathrin-coated pit, and direct penetration of plasma membrane. In addition, cell microvilli might help HAdV-41 enter cells. After entering into cells, HAdV-41 virus particles could be found in vacuoles or lysosomes or be in a free state in cytoplasm. Only free virus particles could be found near nuclear pores (NP), suggesting that the virus needed to escape from lysosomes for effective infection and viral nucleoprotein entered the nucleus through NP. Progeny viruses were as-sembled in the nucleus. Three types of inclusion bodies, which were termed as fibrillous inclusion body, condense inclusion body, and stripped condense inclusion body, were involved in HAdV-41 morphogenesis. In the late phase of viral replication, the membrane integrity of the infected cells was lost and viral particles were released extracellularly. This study reveals the partial process of HAdV-41 morphogenesis and provides more biological information on HAdV-41.

DNA barcoding is a technique in which species identification and discovery are performed by using short and standard fragments of DNA sequences. In this study, eleven species of Paris, including seven varieties, were sampled. Five chloroplast sequences, psbA-trnH, rpoB, rpoC1, rbcL, matK, and one nuclear marker, the second internal transcribed spacer (ITS2) of ribosomal DNA, were amplified and sequenced. The PCR amplification and sequencing efficiency, intra- and inter-specific divergence and barcoding gap were used to evaluate different loci, and the identification efficiency was assessed using BLAST1 and Nearest Distance methods. The ITS2 sequences in the studied samples of Paris were amplified and sequenced successfully using primers designed by our group, while matK showed low level in the amplification and psbA-trnH was difficult for sequencing because of over 800 bp and poly (A) structure. Analysis of the intra- and inter-specific divergence and barcoding gap showed ITS2 was superior to other loci. The ITS2 showed a much higher percentage of success (100%) in identification than other five loci, none of which indicated more than 50% except matK (52.9%). The 2-locus combination of rbcL+matK didn't improve ability of authentication. In addition, the rate of successful identification with ITS2 kept 100% when the samples were expanded to 67 samples of 29 species. In conclusion, ITS2 can be used to correctly identify medicinal plants of Paris, and it will be a potential DNA barcode for identifying medicinal plants of other taxa.

Objective To assess the toxicity risks of diphenylchlorarsine (DA) to environments, human beings and livestock. Methods Totally 120 mice were randomly divided into 6 groups and given DA by gastric gavage at the doses of 32, 30, 28, 26, 24, 22 mg/kg respectively for LD_(50) of DA in mice. The toxicity of DA in rat skin were evaluated by smearing 50 ?l DA at the concentrations of 140, 70, 35, 17.5, and 8.8 mg/ml to an area of 4 cm2, and that of eyes exposure was carried out by dropping 10 ?l DA of 140.7, 70, 7, 0.7 mg/ml in rat eyes. The counterpart skin area and eyes served as control. Results LD_(50) of DA in mice was 28.07 mg/kg, the estimated doses for no-observed-adverse-effect levels (NOELs) were 8.8 mg/ml (0.44 mg) to the skin and 0.7 mg/ml (0.014 mg) to the eyes respectively. Conclusion DA can induce the injuries on the liver, kidneys, esophagus and stomach. High concentration of DA can cause inflammation of the skin and lens opacification, even blind.

AIM: To clone the extracellular domain of N-cadherin cDNA, and to observe the antigenicity of the expressed protein. METHODS: Total RNA was extracted from CD34+ cells separated from fetal liver and bone marrow cells. The extracellular domain of N-cad cDNA was amplified with RT-PCR and inserted into a vector pOPE101-215. The recombinant pOPE-N-cad was expressed with IPTG induction. Then, mice were immunized with the protein. RESULTS: The extracellular domain of N-cad cDNA from CD34+ cells was identified by DNA sequencing. The recombinant pOPE-N-cad in host XL1-blue expressed a 70 kD protein after induced with IPTG, and anti-N-cad antibody was detected in serum of the immunized mice after 5 times injection of the recombinant N-cad protein. CONCLUSION: CD34+ cells bore N-cad gene and the recombinant protein of the extracellular domain of N-cad cDNA shows good immunogenicity.
