Objective To study the change tendency of air pollutants in Shenzhen, China in 2002-2005, further, to explore the relationship between disease spectrum and air pollution. Methods The daily mean concentration of SO2, NO2 and PM10 in 2002-2005 in eight environmental monitoring sites were determined according to Ambient Air Quality Standard. Results Air concentrations of SO2, NO2 and PM10 increased yearly in 2002-2004, from 0.018 3 mg/m3 to 0.023 4 mg/m3, 0.050 1 mg/m3 to 0.072 5 mg/m3, 0.061 0 mg/m3 to 0.075 7 mg/m3, respectively, however, the concentrations of the three indexes decreased in 2005. In the past four yeas, average levels of SO2 were under the limit of grade 2 of GB3095-1996, as for PM10, under the limit of grade 2, and most of the concentrations of NO2 were under the limit of grade 3, but in the other two monitoring sites, the concentrations of NO2 in 2004 exceeded the limit of grade 3. The year average concentrations of SO2, NO2 and PM10 in 2002-2005 in the outer region were higher compared with those in the inner region of the special economic zone, except the level of NO2 in 2002. As for the quarter average concentrations of SO2, NO2 and PM10, 1st and 4th were higher compared with 2nd and 3rd. Conclusion The air quality in Shenzhen is better in China, however, more attention should be paid to the pollution of nitrogen oxides and inhalable particle matters.

Objective To investigate the infection rate of Legionella pneumophila(LP)in children younger than 5 years with lower respiratory infections by ELISA and PCR.Method Serum LP-IgM and IgG were measured by ELISA,and LP DNA in sputum or throat swab were detected by PCR in 300 children less than 5 years with lower respiratory infections.The data were analyzed by chi-square test and the consistency of the two methods was analyzea by NcNemar test.Results Serum antibody detected by ELISA was positive in 17 cases(5.67%),including 10 positive of IgM and 7 positiile of lgG.In these 17 eases,11 were males and 6 were females with similar positive rates(5.76%vs 5.5%).Four cases(2.53%)were positive in children aged from 27 days to 1 year,while 7(7.37%)and 6 cases(12.77%)were positive in children aged 1-3 years and 3-5 years,respectively.Seven cases(5.19%)found in the winter and spring seasons and 10 cases(6.06%)in summer and autumn seasons.Eleven children(11.83%)were from urban area and only 6(2.9%)from countryside.DNA in sputum or throat swab detected by PCR was positive in 16 cases(5.33%),included 10 males and 6 females with similar positive rates(5.24%vs 5.5%).Five cases(3.16%)were positive in children aged from 27 days to 1 year,while 6(6.32%)and 5 cases(10.64%)were positive in children aged 1-3 years and 3-5 years,respectively.Three cases(2.22%)found in the winter and spring seasons and 13 cases(7.88%)in sunmmr and alltumll seasons.Nine children(9.68%)were from urban area and only 7(3.38%)from countryside.McNemar test was used to compare the data of ELISA and PCR results with a Qm of 0.037 and a Pr of 0.8474.Conclusions LP might contribute partly to the lower respiratory infections in children less than 5 years.The infection rate of LP increases with age increasing.Urban children have a higher infection rate than those living in countryside.Both methods have a good consistency.

Objective:To investigate the expression status of Sonic Hedgehog signaling genes and molecules in human hepatocellular carcinomas(HCC),and to explore the relationship between these genes and clinical prognosis.Methods:HCC tissue and adjacent normal tissue from 29 HCC patients were assayed for the expression of hedgehog signaling genes by reverse transcription-polymerase chain reaction chain reaction(RT-PCR) techniques and for the expression of hedgehog signaling molecules by immunohistochemistry.The expressions of Shh,Ptch,Smoh,Gli-1 mRNA were assayed as well as Shh,Ptch proteins in 29 cases of HCC and in 29 liver tissues adjacent to the tumor.Results:Expression of Shh mRNA was detectable in about 51% of HCCs examined.Consistent with this,hedgehog target genes Ptch,Smoh and Gli-1 mRNA were expressed in over 68%,48% and 62% of the tumors,respectively,and the expressions of Shh and Ptch proteins in HCC tumor tissues correlated with those of Shh and Ptch mRNA in tumor tissues(P=0.041 and P=0.035).This suggested that the hedgehog pathway was frequently activated in HCCs.The simultaneous expression of Gli-1 in HCC and liver tissues adjacent to the tumor had significantly relationship with poor prognosis.Conclusion:Hedgehog signaling activation is an important event for development of human HCCs.It also suggests that markers for hedgehog signaling activation may be useful for the determination of prognosis.

Objective To explore clinical application value of Traditional Chinese Medicine nursing technology to decrease postoperative complication after breast cancer surgery.Methods Randomized controlled trial,large sample size,multicenter study design were adopted,and 200 patients who met inclusion criteria were randomly divided into the control group and the treatment group (100 cases in each group).The control group received routine nursing methods after breast cancer surgery.The treatment group received routine nursing methods as well as Traditional Chinese Medicine nursing intervention,such as auricular application pressure,acupoint sticking,meridian moxibustion.Data of arm circumference,Athens insomnia scale(AIS),symptom in affected arm were collected a week before and after surgery,and range of motion of shoulder joint was evaluated 3 months after surgery to compare postoperative subcutaneous effusion,skin flap necrosis,limb edema,sleep disorder and occurrence of shoulder joint dysfunction in two groups.Results The cases developed postoperative subcutaneous effusion,skin flap necrosis,limb edema were different in two groups,but the differences were not statistically significant(P＞0.05).There were significant differences between two groups in affected arm pain,swelling,skin tension,sleep,and shoulder joint dysfunction after 3 months(P＜0.05).Conclusion Traditional Chinese Medicine nursing technology can effectively decrease postoperative complication after breast cancer surgery.

Objective To research the effects of establishing core system key risk index in reducing adverse events. Methods Analyzed the causes of the 147 adverse events in 2014. Including the core system implementation of the reasons for the end of the adverse events caused, the data of fundamental reasons in adverse events and the high risk link that because nurses don′t practice the core system. In 2015, randomly checked the 29 nursing units, including 27 wards and emergency outpatient transfusion room, ICU. Contains the implement rates of the core system in transfusion treatment, day and night shifts, doctors′ advice and patients′ identification. In order to quarterly analysis the index and pertinently improve the results, assessors of quality administration council, head nurse in endemic area and attendant watch keeper are chosen to gather index data. Results After one year of management, the key aspects of the core system execution qualified rate has reached 95%, the check of the implementation of the system, the total pass rate compared with before had increased 6.94%, orders execution system implementation of a qualified rate had increased 9.33%, patient identification system implementation of qualified rate had increased 4.29%, the qualified rate of change of comparison the differences were statistically significant (P<0.05). After the establishment of the core system key risk index management, the adverse events had decreased 11.06%(P < 0.05). Conclusion The establishment of the core system key risk index management can effectively improve the implement rates and reduce the nurse adverse events.

Objective To investigate the schistosomiasis japonica infection and preventive knowledge of immigration popula-tion in Jinshan District,Shanghai so as to provide the evidence for improving the control work. Methods The immigration popula-tion from schistosomiasis endemic provinces and local people were screened by serum IHA screening for schistosome infection, and the positives were further examined by Kato-Katz technique and the miracidium hatching method. The schistosomiasis preven-tive knowledge and behaviors were investigated by questionnaires. Results A total of 579 were investigated with 348 immigration people and 231 local people,and among them,the male accounted for 72.0%and female accounted for 28.0%. In the immigration population,the main age group was 20-29(56.0%),and 56.6%of the immigration had an education level at senior middle school or higher. The most proportion of immigration was from Anhui Province(36.2%). There were 4 IHA positive persons(1.15%)in the immigration,and 1 was positive in the stool test,and the schistosome infection rate was 0.29%. There were no positives in the local people. The schistosomiasis preventive knowledge of the immigration was generally poor,and some people’s behaviors of see doctor and medication were incorrect. Conclusion There are schistosome infected persons among the immigration population from schistosomiasis endemic provinces,and their schistosomiasis prevention knowledge was poor,thus there is a schistosomiasistransmission risk.
