During the surgery, the patient have stable heart rate, oxygen saturation without falling, blood pressure is stable, stable hemodynamics, the patients did not complain of discomfort, without obvious heart and lung failure and other complications occurred, the operation without bleed-ing, pneumothorax, complications. All cases of postoperative respiratory system were improved after operation. The average time stay in hospital was (2.5 ± 1.4) days. Follow-up for 1~24 months (mean, 6 months) in 12 cases found no recurrence of stones and serious respiratory tract infection. Conclusions The method of Dexmedetomidine com-bined with Sufentanil for sedation on broncholiths through of bronchoscope with holmiun laser is safey, feasible and therapeutic effects were clearly, which provides a new method for the clinical on Broncholiths.

Objective To evaluate catheterization in pancreatic duct before endoscopic papillary bal-loon dilation (EPBD)to prevent pancreatitis after EPBD.Methods Forty-three patients with normal serum amylase levels,diagnosed as having bile duct stones,underwent EPBD.Twenty-three were assigned to experi-mental group,where catheters(ERCP imaging tube)were placed in pancreatic duct before EPBD,then the pa-pillary balloon was expanded to 10 mm.Twenty were assigned to control group where eight-millimeter-diameter papillary balloon was used to remove the stones.The serum amylase levels before EPBD,6 hours and 24 hours after EPBD,the incidence of pancreatitis and high serum amylase levels associated with EPBD,as well as the mean time and success rate of removing the stones of the two groups were compared.Results Post-EPBD pan-creatitis occurred in one patient in experimental group (4.35%),and seven in control group (35.00%), which was significantly different(P <0.05).Meanwhile,the mean levels of serum amylase 6 h and 24 h after EPBD in the experimental group were (102.61 ±98.99)U /L and (60.35 ±26.18)U /L respectively,lower than those in the control group (398.25 ±259.32)U /L and (230.50 ±281.31)U /L(P <0.05).After the papillary balloon was expanded to 10 mm in experimental group,the mean time of removing stones was (10.43 ±2.27)min,which was shorter than that of control group (17.90 ±4.49)min (P <0.05).Stone-re-moving rate of two groups had no difference and they all succeeded one time.Conclusion Placing catheter in pancreatic duct before EPBD to prevent pancreatitis after EPBD makes it easier to remove stones in shorter op-eration time.It can prevent pancreatitis and high amylase blood disease after EPBD.

Objective To understand and analyze the infection status of human parasites in Nanchang City, so as to offer a scientific basis for control of parasitic disease. Methods In 2014, a survey was performed according to the scheme of The 3rd National Survey of Principal Human Parasites. Intestinal parasites were surveyed among the residents in Jinxian County and Anyi County, Qingyunpu District and Qingshanhu District in Nanchang City, including the soil-transmitted nematodes (Ascaris lumbricoides, Trichuris trichiura and hookworm), Enterobius vermicularis, tapeworm and intestinal protozoa. Clonorchis sinensis was surveyed among the residents in Qingyunpu District and Qingshanhu District. Toxoplasma gondii was surveyed among the residents in two rural areas (Nanchang County and Xinjian County) and two urban areas (Donghu District and Xihu District). The ovums of the soil-transmitted nematodes, Clonorchis sinensis , tapeworm and other helminths were examined by the Kato-Katz, while Enterobius vermicularis among children was examined by cellophane anal swab, trophozoites and cysts of intestinal protozoa by saline smearing and iodine smearing , and IgG antibodies of Toxoplasma gondii by enzyme-linked immunosorbent assay (ELISA). Results Intestinal parasites were surveyed among 2424 residents in the whole city, in which 2414 residents were tested for the infection of soil-transmitted nematodes and tapeworm;1875 residents were tested for intestinal protozoa infection;74 children were tested for eggs of Enterobius vermicularis; 539 residents were tested for Clonorchis sinensis; and 2400 residents were tested for Toxoplasma gondii. Six kinds of intestinal parasites were found citywide, with a total infection rate of 9.49% (230/2424). The infection rate of soil-transmitted nematodes was 8 . 70% ( 210/2414 ) , in which the infection rate of Ascaris lumbricoides was 0.04% (1/2414), the rate of Trichuris trichiura was 0.91% (22/2414), and of hookworm was 7.83%(189/2414). The infection rate among 3 - 6 years old children of Enterobius vermicularis was 22.97% ( 17/74 ) . Tapeworm and Clonorchis sinensis were not found . The infection rate of intestinal protozoa was 0.21%(4/1875). The positive rate of Toxoplasma gondii's IgG antibody was 5.17% (124/2400). Conclusions In Nanchang City, the infection rate of soil-transmitted nematodes (Ascaris lumbricoides, Trichuris trichiura) and intestinal protozoa was lower. However, the infection rates of hookworm, Toxoplasma gondii and Enterobius vermicularis among 3 - 6 years old children are increasing in local areas. That should be the focus in prevention and control of parasitic disease in the future.

Objective To survey the urinary iodine (UI) status of school children aged from 8 to 10 in Nanchang City, and to provide a scientific basis for preventing and controlling the iodine deficiency disorders (IDD). Methods From 2009 to 2012, Donghu, Xihu, Qingshanhu, Qingyunpu, Wanli, Nanchang, Xinjian, Jinxian and Anyi 9 counties (areas) were chosen in Nanchang City as monitoring areas, and five townships were selected according to the five directions as east, west, south, north and centre in each county (area), one school was selected in each township, 20 school children aged from 8 to 10 (10 males and 10 females) were chosen as respondents. Ammonium persulfate digestion-arsenic cerium catalytic spectrophotometry (WS/T 107-2006) was used to detect UI. The monitoring data on UI of 8 to 10 years old school-age children were collected and analyzed. Results From 2009 to 2012, a total of 3 600 urine samples were collected, the median of urinary iodine (MUI) was 257.35 μg/L. In the 4 years, the MUI of school children aged from 8 to 10 was 315.30, 314.80, 262.92 and 112.73 μg/L, respectively, the MUI decreased year by year, the difference was statistically significant (χ2=631.129, P<0.05). Compared with 2009 and 2010, the proportion [15.22% (137/900), 14.67% (132/900), 25.11% (226/900), 30.22%(272/900)] of MUI of 100 -199μg/L (moderate intake) in 2011 and 2012 increased year by year; the difference was statistically significant (χ2=93.977, P< 0.05). The MUIs between different counties (areas) were statistically significant (χ2=36.520, P<0.05). The MUI of children aged 8 (280.10 μg/L), 9 (255.11 μg/L) and 10 (249.20 μg/L) decreased with increasingage (χ2 = 7.813, P < 0.05). The MUI of male students (269.70 μg/L) was higher than that of female students (247.60μg/L), the difference was statistically significant (Z = - 3.704, P < 0.01). Conclusions Iodine nutrition status of 8 to 10 years old school-age children in Nanchang City is good, iodine intake meets the body's need. It is suggested that the monitoring for UI of school-age children should be strengthened in order to prevent the potential harmful effects of inappropriate iodine intake.

Congenital cataract is a highly heterogeneous disorder at both the genetic and the clinical-phenotypic levels. A unique cataract was observed in a 4-generation Chinese family, which was characterized by autosomal dominant inheritance and late-onset. Mutations in the 13 known genes (CRYAA, CRYAB, CRYBB1, CRYBB2, CRYGC, CRYBA1/A3, CRYGD, Connexin50, Connexin46, intrinsic membrane protein LIM2, cytoskeletal protein BFSP2, the major intrinsic protein-MIP and the heat shock factor HSF4) have previously been demonstrated to be the frequent reason for isolated congenital cataracts, but the exact molecular basis and underlying mechanisms of congenital cataract still remain unclear. This study was designed to find whether these 13 genes developed any mutation in the family members and to identify the disease-causing gene. Polymerase chain reaction (PCR) and direct DNA sequence analysis were carried out to detect the 13 genes. The results showed that no mutation causing amino acid alternations was found in these potential candidate genes among all patients in the family, and only several single-nucleotide polymorphisms (SNPs) were identified. A transitional mutation in the fourth intron of CRYBB2 and some silent mutations in the first exon of BFSP2 and CRYGD were found in the cataract family, but further study showed that these mutations could also be found in normal controls. It was concluded that some unidentified genes may underlie the occurrence of late-onset cataract in this family. A genome-wide screening will be carried out in the next study.

Objective To examine the reliability and validity of the Connor-Davidson Resilience Scale (CD-RISC) in nurses in China.Methods Item analysis and confirmatory factor analysis of CD-RISC was conducted.A total of 1 084 nurses were randomly divided into 2 groups using random number table.One group was used to revise CD-RISC and the other to evaluate its reliability and validity.Results Confirmatory factor analysis of the original RSA showed thatx2/df,RMSEA,GFI,AGFI,CFI were 6.714,0.103,0.804,0.764,and 0.718,respectively.The number of item was reduced to 21 based on exploratory factor analysis results,including three factors which explained 54.034％ of the total variance.Factor loading ranged from 0.490 to 0.755.Coefficient of internal consistency ranged from 0.688 to 0.930 and the 4 week test-retest reliabilities ranged from 0.825 to 0.917.The factor scores were closely correlated with the total scores with correlation coefficient ranging from 0.683 to 0.943.The factors were closely correlated with each other with correlation coefficient ranging from 0.564 to 0765.The confirmatory factor analysis of the revised CD-RISC showed that x2/df,RMSEA,GFI,AGF,CFI were 3.304,0.065,0.902,0.878,and 0.913 respectively.The total scores and all factors were negatively correlated with depression and anxiety and somatization.Conclusions The revised CD-RISC has good psychometric properties and can be used to measure the resilience of nurses.

Objective To investigate the endemic situation of human Toxoplasma gondii infection in Nanchang City in 2014 and analyze the influencing factors,so as to provide the evidence for control measures. Methods The high?risk population of T. gondii infection in Nanchang City was collected as an experiment group,and a control group was settled with the ratio of 1∶1. The serum tests and epidemiology surveys were conducted simultaneously,and the influencing factors were analyzed. Results The total positive rate of human T. gondii was 5.17%(124/2 400)among the whole population in Nanchang City in 2014. The positive rate was 7.50%(90/1 200)in the experiment group and 2.18%(34/1 200)in the control group,and the difference was significant(χ2=26.668,P<0.05). The results of univariate analysis indicated that different dietary habits and health habits were closely related to the infection of T. gondii(χ2=16.522,64.954,both P<0.05). The result of Logistic analysis showed that the risk factors of T. gondii infection were occupation,educational levels,raising cats,contacting animals or raw meat,and eating raw or uncooked beef. Conclusion The high risk population of T. gondii infection is the key population of the toxoplas?mosis control. Unhealthy dietary and living habits are key influencing factors of toxoplasmosis,and the related health education and surveillance work should be strengthened.
