Objective To analyze the karyotypes of 11 cases of Turner syndrome with marker chromosome,and study the phenotypic effects resulting from the abnormal karyotype.Methods Eleven Turner syndrome patients had a mosaic karyotype and carried a marker chromosome,and 6 marker chromosomes were ring chromosomes.Their karyotypes were showed as mos.45,X/46,X,+mar or mos. 45,X/46,X,+r.Fluorescence in situ hybridization(FISH)technique with X/Y centromere probes was performed to determine the origin of the marker chromosome.Reverse chromosome painting technique was used to identify the breakpoints of two largest markers.Phenotype effects with different chromosome breakpoints were compared.Results All the 11 marker chromosomes were ring X chromosomes.The breakpoints of the r(X)were involved in Xp22,Xq22,Xq24 and Xq26,etc.Conclusions The marker chromosomes in Turner syndrome mainly originate from X chromosome and form ring chromosome X.Each r (X)in our patients was mosaic,indicating it was originated from mitosis error during early embryo development.To analyze the origin of the marker chromosome and the breakpoint of r(X)will provide guidance for the therapy and prognosis of the Turner syndrome patient.

Abstract: Objective　To analyze the emergency response and long-term intervention effects after the detection of infectious snails epidemic by loop-mediated isothermal amplification (LAMP) assays in Hannan District, Wuhan City, and to explore the application of LAMP in early surveillance and early-warning of schistosomiasis transmission. Methods Snails picked up by the risk monitoring system in Hannan District were examined by anatomical microscopy and LAMP technology to identify the schistosomiasis infection. Emergency response and intensive intervention were initiated in the environment where positive snails appeared, and the long-term effects were evaluated. Results In May 2018, the infectious snails were detected by LAMP technology in Hannan District, and the positive snails were located in Zhujiacha, Dongzhuang Village, Obstacles and weeds were removed and buried by machine in Zhujiacha. 12 700 m2 of snails were killed by drugs, and the mortality rate of snails was more than 80%; no new seropositive persons were found in the emergency examination within 500 m of the positive snail sites. 506 people were examined in Dong Zhuang Village at the end of the year, and 30 positive IHA cases were detected with a blood positive rate of 5.93%, no positive fecal test was found, and all positive blood test patients took preventive medication. The monitoring results of sentinel rats and wild feces were all negative. Health education was carried out, 7 warning signs were deployed and refreshed, and 500 publicity brochures were distributed. After nearly three years of intensified intervention and monitoring in the villages where the positive environment is located, and the density of snails on the stubborn snail has dropped from 0.094/frame to 0.027/frame, and the positive rate of blood test in Dongzhuang Village has steadily dropped from 5.93% to 3.74%. Conclusions The infected snails missed by microscopy were detected by LAMP in Hannan District, which created conditions for the rapid emergency treatment of environment and elimination of positive snail and improved the sensitivity of the surveillance and early warning system in transmission-interrupted areas.

In order to develop a rapid detection kit for novel avian influenza virus (AIV) subtype H7N9, two sets of specific primers and probes were designed based on the nucleotide sequences of hemagglutinin antigen (HA) and neuraminidase antigen (NA) of novel H7N9 virus (2013) available in GenBank to establish the method of TaqMan probe-based multiplex real-time RT-PCR for rapid detection of AIV subtype H7N9. The primer and probe of HA were for all H7 subtype AIVs, while the primer and probe of NA were only for novel N9 subtype AIVs. The results showed that this method had high sensitivity and specificity. This method was applicable to the testing of positive standard sample with a minimum concentration of 10 copies/microL; it not only distinguished H7 subtype from H1, H3, H5, H6, and H9 subtypes, but also distinguished novel N9 subtype from traditional N9 subtype. A total of 2700 samples from Zhuhai, China were tested by this method, and the results were as expected. For the advantages of sensitivity and specificity, the method holds promise for wide application.

Objective To explore the effect of evidence-based nursing during preoperative interview for abdominal surgery patients' recovery after general anesthesia. Methods 124 patients who accepted selective operation on abdominal region were randomly divided into evidence-based group and control group, 62 cases ineach group. On the base of routine method in the preoperative interview, the evidence-based group established evidence-based information supporting system, which aimed to dredge the psychological stress of the patients'response to surgery individually and intervene by demonstrating simulation of operation process. According to the traditional way, control group accepted routine preoperative interview. To compare patients' indexes of two groups before and after anesthesia. Results Patients' heart rate and the mean arterial pressure lower than control group before anesthesia in evidence-based group. The dosage of midazolam in evidence-based group was less than the control group (t =6. 73,7. 24,8. 17;P <0. 05). The difference of pre-anesthesia anxiety scores was statistically significant between evidence-based group and control group (t =7. 68 ,P <0. 01 ). But the difference of the anxiety scores after operation wasn' t statistically significant between two groups ( t = 0. 62, P > 0. 05 ). Patients in evidence-based group took shorter revival time than control group ( t = 9. 71,10. 45,11.32 ; P < 0. 01 ). Compared the different period pain score of two groups, patients of evidence-based group were lower than those of the control group, and the patients' satisfaction scores also were higher than those of control group, the differences were statistically significant (t =2. 38,5. 22,2. 63,7. 62;P <0. 05). Conclusions Application evidence-based nursing information support in preoperative interview effectively relieves the preoperative anxiety, can reduce the dosage of narcotic and sedative drugs, shorten the revival time, improve patient' s satisfaction and have reached the antieipant effects.

OBJECTIVETo study the curative effects of pirfenidone (PF) on pulmonary fibrosis induced by paraquat (PQ) in mice and to provide the theoretical basis for clinical treatment.

METHODSNinety adult healthy male ICR mice were randomly divided into six groups: control group, PQ group, 2 mg/kg Dexamethasone group, 25 mg/kg PF group, 50 mg/kg PF group and 100 mg/kg PF group, there were 15 mice in each group. The corresponding volume of normal saline was given to the each mouse in control group according to the weight, after 2 h 0.1% CMC was given to the each mouse of control group one time by intragastric administration, then the CMC was administrated at regular time until sacrifice. All mice for other 5 groups were exposed to 100 mg/kg PQ by intragastric administration. At 2 h after exposure to PQ, 0.02 ml/10 g dexamethasone and 25, 50, 100 mg/kg PF were given to mice for dexamethasone group and for 3 PF groups by intragastric administration each day for 49 days, respectively. The lung coefficient was calculated and pathological changes of lung tissue were observed by HE staining for each mouse. The hydroxyproline (HYP) level in lung tissue was measured for each mouse. The mRNA level of and the protein level of TGF-β(1) in lung tissue for each mouse were determined, and the protein level of TGF-β(1) in the bronchus-alveolus lavage fluid (BALF) of each mouse was detected.

RESULTSThe survival rates on the 3rd day in PQ group, 3 PF groups and dexamethasone group were 53.33%, 46.67%, 73.33%, 86.67% and 80%, respectively. The survival rates on the 3rd day in dexamethasone group, 50 mg/kg and 100 mg/kg PF groups were significantly higher than those of PQ group and 25 mg/kg PF group (P < 0.05). The lung coefficients of 3 PF groups were significantly lower than that of the PQ group (P < 0.05). The lung tissue HYP levels of dexamethasone group and 3 PF groups were 50.95 ± 11.65, 44.52 ± 9.48, 43.27 ± 6.01 and 40.82 ± 5.90 mg/g respectively, which were significantly lower than that (74.27 ± 3.68) of PQ group (P < 0.01). The TGF-β(1) protein levels of BALF in dexamethasone group, 50 and 100 mg/kg PF groups were 22.03 ± 7.27, 27.75 ± 5.84 and 21.31 ± 6.82 ng/ml respectively, which were significantly lower than that (52.52 ± 15.51) ng/ml of PQ group (P < 0.01) The expression level of TGF-β(1) mRNA in 100 mg/kg PF group decreased significantly, as compared with PQ group (P < 0.01).

CONCLUSIONPF could reduce the collagen deposition and pulmonary fibrosis induced by PQ in mice lungs.

To evaluate the effects of p-octyl polyethylene glycol phenyl ether (Triton X-100), polyoxyl 35 caster oil (EL35) and polyoxyl 40 hydrogenated caster oil (RH40) on the activity of Cytochrome P450 3A (CYP3 As) in vivo. Rats were administered with saline, ketoconazole (75 mg x kg(-1) x d(-1)), Triton X-100 (30 mg x kg(-1) x d(-1)), EL35 (150 mg x kg(-1) x d(-1)) and RH40 (150 mg x kg(-1) x d(-1)) intragastrically for 5 consecutive days, and then given midazolam 10 mg x kg(-1) 20 min after the last treatment of ketoconazole or three surfactants with the same dose through duodenal administration. Pharmacokinetics parameters for midazolam and its metabolite 1'-hydroxymidazolam were estimated from the plasma concentration-time data by a noncompartmental approach. The results showed that multiple dose administration of Triton X-100, EL35 and RH40 decreased the ratios of 1'-hydroxymidazolam and midazolam AUC0-infinity from 1.14 to 0.90, 1.03 and 0.64, respectively. In contrast, multiple dose administration of ketoconazole caused the ratios of 1'-hydroxymidazolam and midazolam a significant decrease to 0.50. This study indicated that Triton X-100 and EL35 would have no inhibition on CYP3A, while RH40 had significant inhibition on CYP3A. Therefore, RH40 might be used to prepare drug formulations in pharmaceutical industry and would increase the bioavailability of some drugs transformed by CYP3As and further lead to significant clinical pharmacologic effects.

OBJECTIVETo investigate the antithrombin (AT) activity (AT: A) and AT antigen (AT: Ag) level in a Chinese family with type I antithrombin (AT) deficiency, and to explore the molecular mechanism of AT deficiency.

METHODSImmuno-nephelometry and chromogenic assay were used to detect the plasma level of AT: A and AT: Ag, respectively. Genomic DNA was isolated from the peripheral blood, and all the seven exons and exon-intron boundaries of AT gene were amplified by PCR and direct sequencing.

RESULTSThe plasma levels of AT: A and AT: Ag of the proband were 45% and 97 mg/L, respectively, which led to a type I AT deficiency. A heterozygous T to A mutation was found at nucleotide 9833 in exon 5 resulting in a Tyr363Stop nonsense mutation. The sequencing results from the pedigree indicated that four other members also had this mutation.

CONCLUSIONThis heterozygous nonsense mutation of T9833A in exon 5 resulting in venous thrombosis is a novel genetic defect of hereditary AT deficiency, which has not been described before.

To examine the phylogenetic information regarding the gene pool of AIV in domestic ducks in eastern China, the NA genes of twenty-six viruses isolated during 2002-2006, including two H1N1 strains, tenH3N1 strains and fourteen HSN1 strains, which reflected the predominant N1 subtype viruses were subjected to phylogenetic analysis. The results indicated that AIVs of N1 subtype circulating in domestic ducks in eastern China were undergoing a gradual evolution. Analysis of the deduced amino acid sequences revealed that NAs from all isolated H5N1 viruses had a 20-aa deletion in the stalk region (residues 49-68), whereas no deletion was seen in the NAs from other HA subtype viruses. The viruses of H3N1 and H1N1 might have a propensity for reassortment of NA genes, whereas no direct evidence of reassortment of NA gene was obtained in H5N1 viruses.
