sers should offer good care in mental, physical, social aspects to improve their comfortable state.

Herpes simplex virus (HSV), a member of the Herpesviridae family, is a significant human pathogen that results in mucocutaneous lesions in the oral cavity or genital infections. Acyclovir (ACV) and related nucleoside analogues can successfully treat HSV infections, but the emergence of drug resistance to ACV has created a barrier for the treatment of HSV infections, especially in immunocompromised patients. There is an urgent need to explore new and effective tactics to circumvent drug resistance to HSV. This review summarises the current strategies in the development of new targets (the DNA helicase/primase (H/P) complex), new types of molecules (nature products) and new antiviral mechanisms (lethal mutagenesis of Janus-type nucleosides) to fight the drug resistance of HSV.

Methods The endemic areas of Yile, Wufeng's Songlinwan, Tangfang and Wufeng's Wugu in Zhenxiong county, and a non-endemic area Xiaguan in Dali city were selected as study sites. Ten samples of fresh corn and pepper were collected in each region, and fluorine was determined using acid leaching/potentiometry freshly and after baking or drying for 10 days or 4 months, respectively. Results The fluorine content of local fresh corn in Xiaguan of Dali city and Yile,Wufeng's Songlinwan, Tangfang, Wufeng's Wugu in Zhenxiong county were (1.31 ± 0.13),(1.65 ± 0.64),(1.92 ±0.37), (2.32 ± 0.49), (1.98 ± 0.66)mg/kg, respectively, and there were statistically significant differences across the regions(H = 27.871, P ＜ 0.05). The fluorine content of corn samples after baking or drying for 4 months were ( 1.82 ± 0.17), (26.43 ± 12.03), (39.27 ± 8.09), ( 14.27 ± 4.37), ( 14.33 ± 1.73)mg/kg, respectively, which were significantly higher than that of the fresh com in the corresponding region(all P ＜ 0.05 ), and there were statistically significant differences across the regions(H = 42.512, P＜ 0.05). The fluorine content of the local fresh chili were (3.34 ± 1.08), (3.44 ± 0.55), (3.47 ± 0.74), (3.46 ± 0.93)mg/kg, respectively, in the 4 observed places in Xiaguan of Dali city and Yile, Wufeng's Songlinwan, Tangfang in Zhenxiong county, and there were no statistically significant differences across the regions (F = 0.052, P ＞ 0.05 ). The fluorine content of pepper samples after baking or drying for 4 months were (7.01 ± 1.64), (226.07 ± 83.69), (179.36 ± 148.37), (54.51 ± 34.67)mg/kg,respectively, which were significantly higher than that of the fresh pepper in the corresponding region(all P ＜ 0.05 ),and there were statistically significant differences across the regions(H = 28.822, P ＜ 0.05). Conclusion Corn and chili fluorine is significantly increased after baked with coal and clay-mixed with coal by farmers in Zhenxiong county, a coal- burning borne endemic fluorosis area of Yunnan province.

OBJECTIVETo identify the mutations of iduronate-2-sulfatase (IDS) gene in mucopolysaccharidosis type II patients.

METHODSPCR-SSCP analysis was applied to detect the common mutations in the exons 2, 3, 5, 7, 8, 9 in IDS-gene of the patient. DNA sequencing and PCR-RFLP were applied to analyze the mutation detected by PCR-SSCP.

RESULTSA new mutation(1253G-->T) of exon 7 of the IDS gene was found by PCR-SSCP and DNA sequencing in the patient, The PCR-restriction enzyme digestion showed that enzyme digestion location appeared in the patient and his mother, which verified the results of sequencing analysis.

CONCLUSIONThe mutation of patient with MPSII could be detected effectively and quickly by the applications of PCR-SSCP, DNA sequencing and PCR-restriction enzyme digestion analysis, and the new mutation thus detected is necessary for the prenatal diagnosis of the pedigree.

OBJECTIVETo define cut-off values of plasma amino-terminal pro-B-type natriuretic peptide (NT-ProBNP) for the diagnosis of congenital heart failure (CHF) and evaluate the importance of plasma NT-ProBNP measurement in the assessment of cardiac function prior to heart surgery in infants with congenital heart disease (CHD).

METHODSPlasma levels of NT-proBNP were measured in 120 infants with CHD before heart surgery and in 100 age-matched healthy infants between June 2010 and June 2013. The data were stratified based on the presence or absence of CHF in the whole group of CHD infants and on age (i.e., <1 year and ≥1 year) and time (i.e., before surgery) within the subgroup of CHF infants.

RESULTSOf the 120 infants with CHD, 41 met the criteria for CHF defined in the Ross Classification for Heart Failure in Infants.The cut-off values of plasma NT-ProBNP were ≥498 ng/L for infants of all ages, 557 ng/L for <1 year age group and 452 ng/L for ≥1 year age group, respectively, in the 41 CHF patients. In CHF infants, plasma NT-proBNP was significantly decreased after protecting of cardiac function (P<0.001).

CONCLUSIONSThe cut-off values of plasma NT-ProBNP for CHF differ between infants <1 year and infants ≥1 year. Moreover, plasma NT-ProBNP can be used as an additional parameter in the preoperative assessment of cardiac function in CHD infants.
