Objective To investigate the water source pollution by parasitic protozoa in small towns and villages in Shenzhen,China,in order to present the data to establish the national hygienic standard for controlling parasitic protozoa pollution.Methods The samples of water source were collected from 8 village level water plants in Shenzhen.Giardia lamblia and Cryptosporidium were detected,according to the EPA methods,by filtering,rinsing,magnetic isolation and staining.Results Giardia lamblia was found in water sources of 6 water plants and Cryptosporidium was found in one water plant.Conclusion At present,some water sources of village level water plants where the reservoirs were used as the water source in Shenzhen have been polluted by Giardia lamblia and Cryptosporidium,that indicates the potentiality of the water-born-diseases in that areas.

Objective To explore the value of dynamic contrast-enhanced CT for differentially diagnosing benign and malignant the solitary pulmonary nodules. Methods 117 solitary pulmonary nodules proved by histopathological examination were enrolled in this study. Thin-section CT scanning was performed before and 1,2,3,4 and 5 minutes after contrast enhancement. Results The enhanced value of malignant nodules (39.6?15.8)Hu was significantly higher than that of benign nodules (19.18?17.23)Hu (P

Objective To study the factors such as artificial abortion frequency, pregnancy time and so on on development of adeno-myosis (AM). Methods A retrospective analysis was carried in 462 patients who were from the department of gynaecology and obstetrics in Affiliated Hospital of Nantong University and Beijing Aviation Center Hospital from January 2004 to December 2008. The patients were divided into two groups: AM and no - AM. The two groups were compared for abortion frequency, pregnancy time, age, menarche age and so on. Results There were no significant differences between the two groups in age, menarche age, age of the first artificial abor-tion, bearing frequency, IUD with pregnancy and so on(P > 0.05). The proportion of patients with repeated artificial abortion or history of curettage of uterus in AM group was higher than that in the no - AM group. The patients with pregnaney time more than 8 weeks who re-ceived artificial abortion had higher rate of development of AM. Conclusion Repeated artificial abortion, pregnancy time and history of curettage of uterus were the risk factors of development of adenomyosis.

0.05).The proportion of patients with repeated artificial abortion or history of curettage of uterus in AM group was higher than that in the no-AM group.The patients with pregnancy time more than 8 weeks who received artificial abortion had higher rate of development of AM.Conclusion Repeated artificial abortion,pregnancy time and history of curettage of uterus were the risk factors of development of adenomyosis.

Objective To study and design a new algorithm of QT interval measurement based on multi-scale morphological derivative transform(MMDT) according to the demands of mobile monitoring platform.Methods After the MMDT of ECG signals by inducing a triangle and a short line as a pair of structure elements,they were classified into four types by their morphological characteristics and the optimal strategy for each type was described to detect the onset of Q-wave.By introducing the "wing" function,two referenced points of T peak were picked out,which was helpful to locate the peak and offset of T wave,and improve the precision and recognition rate of MMDT method when detecting the bifid T wave(90.9%)and biphasic T wave(86.7%).Results Eighty data records from CSE database were used to evaluate the availability.By contrast with the wavelet transform method,the statistical results showed that the proposed algorithm had generally less error and smaller standard deviation especially for abnormal-phase T wave.Conclusion Compared with those algorithms based on wavelet transform and self-adaptive threshold techniques,our algorithm needs less empirical parameters and calculation.It is also suitable for mobile monitoring and HOLTER system,and has a wide prospect of application.

Objective To estimate reliability of magnetic resonance elastography (MRE) in measuring liver stiffness of volunteers and patients with chronic liver disease and to assess inter-rater consistency.Methods MRE was performed on a 3.0 T scanner in all subjects,including 24 volunteers (control group) and 64 patients with liver disease (chronic liver disease group).Liver stiffness was measured blindly by two raters.The pathological fibrosis score was applied as a standard reference for liver fibrosis in 22 patients.The intraclass correlation coefficient (ICC) was used to evaluate inter-rater reliability.The differences of liver stiffness between two groups were evaluated using non-parametric MannWhitney U test.Spearman analysis was used to analyze the correlation between fibrosis stages and liver stiffness.Results The intraclass correlation coefficient of liver stiffness was perfect (ICC =0.99,P ＜ 0.01)between two raters.There was significant difference of mean stiffness between control group and patient group (U =90.5,P ＜0.01) with(2.35 ±0.34) kPa and(4.17 ± 0.47) kPa,respectively.The correlation between fibrosis stage (3,3,5,5 and 6 patients in fibrosis stage S0,S1,S2,S3 and S4) and stiffness (2.13,3.25,3.82,5.45 and 7.35 kPa) was very strong (r =0.96,P ＜0.01).Conclusion MRE is a reliable and promising tool to measure liver stiffness and to assess liver fibrosis.

AIM: To study the clinical efficacy and safety of intravenous immunoglobulin (IVIG) for infant with severe pneumonia.　METHODS: Seventy patients of infant with severe pneumonia were divided into 2 groups. Patinets (n=50) of the trea- tment group (M 30, F 20; age 6 mo± s 5 mo) were treated with IVIG and conventional drugs, IVIG 400 mg*kg-1*d-1 for 3 d. Patinets (n=20) of the control group (M 12, F 8; age 7 mo±7 mo) were treated with conventional drugs.　RESULTS: The duration of fever, tachypnea, high heart rate shortened. The gasp and rales disappeared earlier. The cardiac failure recovered faster than the control group. There was significantly diffference statistically (P<0.05). The level of IgG, IgA raised after treatment. There was significantly difference statistically (P<0.01). The level of CD+3, CD+4, CD+8 after treatment also raised significantly compared with that before treatment (P<0.05). IL-6 and IL-8 after treatment reduced. There was significantly difference statistically (P<0.05).　CONCLUSION: IVIG is safe and effective drug in adjuvant treating severe pneumonia of infant, specially RSV pneumonia.

Pullulan is a linear glucosic polysaccharide produced by the polymorphic fungus Aureobasidium Pullulans, which has long been applied for various applications in medical and food industry due to its security, stability and low adhesive ability.At present, the two problems in restricting pullulan industrial production are the low polysaccharide production and melanin secreted which is hard to erase completely, giving the following process some problem.As a starting point, this review article collects and analyzes the progress on the breeding of pullulan high-yield strain without melanin in recent years, in order to find more efficient strains breeding methods, laying a foundation for further breeding of pullulan high-yield strain without melanin.

Objective To compare everolimus (EVR) with calcineurin inhibitor (CNI) minimization or withdrawal on renal function of liver transplant patients with standard CNI therapy.Methods A search was conducted on databases which included the PubMed,Embase and Cochrane library for randomized controlled trials (RCTs) comparing EVR with CNI with minimization or withdrawal (the EVR group) with standard CNI therapy (the standard CNIs group) on renal function of liver transplant patients.A metaanalysis was performed using RevMan 5.3 software.Results Five RCTs which included 1 264 patients were selected into this study.There were 790 patients in the EVR group and 474 patients in the standard CNIs group.On meta-analysis,the EVR group had significantly better renal function (SMD =0.36,95％ CI 0.09 ～ 0.64,P ＜ 0.05),but higher rates of infection (RR =1.37,95％ CI 1.08 ～ 1.74,P ＜ 0.05),dyslipidemia (RR =2.46,95％ CI 1.79 ～ 3.38) and leukopenia (RR =2.37,95％ CI 1.32 ～ 4.26).No significant differences were found on the mortality and the acute rejection rates between the two groups (all P ＜ 0.05).Conclusions EVR with CNI minimization or withdrawal after liver transplantation provided effective immunosuppression and improved patients' renal function.The treatment increased the rates of infection,dyslipidemia and leukopenia.
