Objective To investigate the effects of tropicamide and esculin-digitalisglycosides combination eye drops on low myopia of children (age ranging from 6 to 14). Methods Eighty children with 160 eyes of low myopia in the outpatient department of ophthalmology of our hospital were chose from July 2010 to April 2013, then the patients were equally divided into four groups:the control, esculin-digitalisglycosides eye drops,tropicamide,and tropicamide and esculin-digitalisglycosides combination groups. The naked vision and myopia correction of each group were compared before and after treatment for two weeks, and the treatment effects were compared among four groups. Results (1) The results showed there were no significant changes before and after treatment in the control, esculin-digitalisglycosides eye drops and tropicamide groups ( >0.05); (2) On the contrast, the tropicamide and esculin-digitalisglycosides combination have significantly improved naked vision and myopia correction after 2 weeks ( <0.05);(3) Prior to the treatment,there was no significant difference among four groups (<0.05);(4) After treatment,group under tropicamide and esculin- digitalisglycosides combined was statistical different from the other groups treated with other three eye drops ( <0.05);However, there was no statistical difference among groups in these three eyedrops. Conclusion Esculin-digitalisglycosides combined with tropicamide was the most effective treatment for low myopia of children.

Study the infect of child anorexia granule on serum ghrelin and leptin of anorexia children and its clinical efficacy. Selected 81 cases of anorexia children aged 1-6 years old into treatment group (42 cases) and control group (39 cases), in addition, 30 case healthy children as healthy control group. The control group children were treated with domperidone suspension 0.3 mg x kg(-1) x d(-1), tid, orally 30 minutes before meals. Treatment group were treated with child anorexia granule, 1-3 years 1 package, bid; 4-6 years 1 package, tid; po, 4 weeks as a course of treatment. Study the change of serum ghrelin and leptin before and after therapy. The study demonstrates that before treatment, the serum ghrelin level of disease group was lower than healthy group (P < 0.01), and the serum leptin level was higher than healthy group (P < 0.01). After treatment, the serum ghrelin level both increase, and the serum leptin decline. And the change of treatment group was significantly different with control group (P < 0.01). And the clinical effective rate are 95.23% and 74.35% (P < 0.01). After 6 months of follow-up visit, the children weight significantly increase in treatment group (P < 0.01). Results indicate that child anorexia granule can facilitate secretion of ghrelin, and inhibit secretion of leptin, so as to work up an appetite. And the molecular mechanism is its infect on serum ghrelin, leptin.

Objective To discuss the frequent etiology of spontaneous sub-cortical hemorrhage and its diag- nosis.Methods The clinical materials of 79 cases of spontaneous sub-cortical hemorrhage were analyzed.Results 56% of the hemorrhage was caused by arterial-venous malformation.48% of the hemorrhage was caused by occult AVM.Conclusion AVM is the most frequent etiology of spontaneous sub-cortical hemorrhage.CTA plays a special role in its diagnosis.

OBJECTIVETo explore the association of 8-hydroxyguanine glycosidase OGG1 Ser326Cys polymorphism with semen quality and the risk of male infertility.

METHODSThis case-control study included 620 idiopathic infertile patients and 385 normal fertile controls. We determined their genotypes by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and analyzed their semen quality by computer-aided semen analysis (CASA).

RESULTSThe individuals with OGG1 326 Cys/Cys showed significantly lower sperm motility and concentration ([52.1 +/- 26.7]% and (3.75 +/- 0.91) x 10(6)/ml, ln transformed value) than the Ser/Ser carriers ([59.0 +/- 21.8] % and (4.12 +/- 0.88) x 10(6)/ml, ln transformed value) (P < 0.05). The risk of male infertility increased 69% in the OGG1 326Cys allele carriers as compared with the Ser carriers (OR = 1.69, 95% CI: 1.24 -2.31).

CONCLUSIONOGG1 326 Ser/Cys polymorphism might contribute to the risk of male infertility in the southern Chinese population.

Taxol is one of the most potent anti-cancer agents, which is extracted from the plants of Taxus species. Isopentenyl diphosphate isomerase (IPI) catalyzes the reversible transformation between IPP and DMAPP, both of which are the general 5-carbon precursors for taxol biosynthesis. In the present study, a new gene encoding IPI was cloned from Taxus media (namely TmIPI with the GenBank Accession Number KP970677) for the first time. The full-length cDNA of TmIPI was 1 232 bps encoding a polypeptide with 233 amino acids, in which the conserved domain Nudix was found. Bioinformatic analysis indicated that the sequence of TmIPI was highly similar to those of other plant IPI proteins, and the phylogenetic analysis showed that there were two clades of plant IPI proteins, including IPIs of angiosperm plants and IPIs of gymnosperm plants. TmIPI belonged to the clade of gymnosperm plant IPIs, and this was consistent with the fact that Taxus media is a plant species of gymnosperm. Southern blotting analysis demonstrated that there was a gene family of IPI in Taxus media. Finally, functional verification was applied to identify the function of TmIPI. The results showed that biosynthesis of β-carotenoid was enhanced by overexpressing TmIPI in the engineered E. coli strain, and this suggested that TmIPI might be a key gene involved in isoprenoid/terpenoid biosynthesis.

Objective To study the effects of hormone,anesthetie and contrast medium on the activities of collagenase lysis.Methods Nuclear tissues were divided into equal amount for different groups and same units of collagenase were used for the lysis.The only difference in the control group from experimental groups was that there were no dexamethasone,lidocaine or omnipaque but existing in experimental groups.Twenty four hours later,the concentrations of the hydroxyproline were determined in different groups and the data were analyzed by statistical software with computer.Results 1.The concentrations of hydroxyproline in the dexamcthasone group,lidocaine group and omnipaque group were significantly lower than that of control group,especially that of lidocaine group,P value was＜0.05 or 0.01.2. The concentrations of hydroxyproline in the dexamethasone+lidocaine group,dexamethasone+omnipaque group,lidocaine+omnipaque group and dexamethasone+lidocaine+omnipaque group were significantly lower than that of control group;and simultaneously lower in dexamethasone group,lidocaine group,omnipaque group respectively;P value was also＜0.05 or 0.01.Conclusion Dexamethasone,lidocaine and omnipaque can individually inhibit the activity of collagenase at different degrees,so they shouldn't be used together with collagenase in treating the lumber disc herniation.

Objective To find out the relation between element (non-iodized salt and iodized salt that below standard) and epidemic strength of iodine deficiency disorders and level of iodine, in order to find out the factors affecting the result of using iodized salt in controlling of this disorders. Methods Retrospective analyses was used in the study. Six counties were selected randomly from Zhangjiakou every year from 2000 to 2008, and these counties were randomly divided into non-iodized salt group (the ratio of non-iodized salt > 5%), iodized salt below standard group (the ratio of qualified iodized salt < 95%) and control group (the ratio of using qualified iodized salt > 95%). The indexes from different groups were compared as well as the ratio of large thyroid syndrome in children aged 8-10 years and the level of iodine in urine. Results The number of iodized salt monitored were 12 468 units from 2000 to 2008. We examined 5655 children's thyroid and collected 4404 urine samples. The median was 30.1 mg/kg for the average of iodized salt and 7.30% (232/3180) for ratio of non-iodized salt in noniodized salt group, while 30.9 mg/kg and 93.10%(3776/4056) in iodized salt below standard group, and 32.0 mg/kg and 99.27%(5194/5232) in control group. Compared the median of the three groups[5.31%(78/1468) ,4.84% (92/1902) ,2.06% (47/2285)], we observed significant difference (χ2 = 72.07, P < 0.05), especially the ratio of large thyroid in non-iodized salt group which was apparently higher than that of the control group (χ2 = 8.70, P < 0.017). However there was no significant difference between iodized salt below standard group and non-iodized salt group(χ2 = 6.83, P > 0.017) and control group(χ2 = 5.65, P > 0.017). The median of urinary iodine was 188.20 μg/L in non-iodized salt group, 219.62 μg/L in iodized salt below standard group and 262.39 μg/L in control group, indicated that the index in control group was higher than that of others. Conclusion Both of non-iodized salt and iodized salt below standard have effect on prevalence of child iodine deficiency disorders, especially the non-iodized salt.

Objective To analyze the monitoring results of urinary iodine of students aged 8 - 10 in Zhangjiakou city,problems in monitoring results,and to provide basic information for working out control strategies of iodine deficiency disorders.Methods A township(town,street) in each country of each city(district) in Zhangjiakou was selected according to 5 positions of the east,the west,the south,the north and center,and 1 village elementary school was sampled in each chosen township,twenty students(half male and female) aged 8 - 10 were selected to collect their urine samples in each school.Urinary iodine concentration was determined by arseniccerium method.Results The median of urinary iodine of the 1700 children aged 8 - 10 was 291.5 μg/L,with ＜ 50 μg/L accounted for 0.8％(13/1700),50 ～ 99 μg/L about 4.9％(83/1700),100 - 199 μg/L about 20.5％ (349/1700),200 - 299 μg/L about 29.7％(504/1700),and ≥300 μg/L about 44.9％(764/1700).Conclusions Urinary iodine has reached the elimination standard of iodine deficiency disorders in Zhangjiakou city.But the situation of more than adequate amount of urinary iodine and iodine excess is relatively serious and it is necessary to lower iodine concentration.

ObjectiveTo master iodized salt monitoring results in Zhangjiakou city Hebei province,search problems in these monitoring results,and provide a basis for the development of control measures to iodine deficiency disorders.MethodsBy 2010,in Zhangjiakou city,nine salt samples were collected to detect the iodine level in each processing,packing and wholesale enterprise according to their orientation of east,west,north,south and center positions.In each county(district) with nine townships(towns,street offices) and more,nine townships (towns,street offices) were selected according to their east,west,south,north and center positions,in each township (town,street office ) selected,four villages (neighborhoods) were selected,eight residents per household in each village (neighborhood) chosen were selected,and an edible salt was collected in each household to test iodine level; in a county(district) with nine or less townships(towns,street offices),five townships(towns,district offices) were selected according to their east,west,south,north and center positions,four villages (neighborhoods) were selected,and 15 residents per household in each village(neighborhood) were selected to test the iodine level in an edible salt samples;after population-weighted calculation,indicators of iodized salt monitoring were calculated.ResultsA batch quality pass rate of processing,packing and wholesale enterprise was 100％(192/192); the rate of weighted non-iodized salt in a household was 0.04％(2/4932),iodized salt coverage rate was 99.96％ (4930/4932),iodized salt passing rate was 99.55％ (4908/4930),and qualified iodized salt coverage rate was 99.51％ (4908/4932).ConclusionsMonitoring indicators of iodized salt in Zhangjiakou city have reached the standand to eliminate iodine deficiency disorders.However,there still have unqualified iodized salt and non-iodized salt,and the monitoring and iodized salt market management should be strengthened.
