BACKGROUND: The etiology and pathogenesis of Tourette syndrome(TS)is still unacknowledged, and related studies on the relationship between TS and hypoironemia are unavailable. Since hypoironemia has been found existed in children with TS who showed better outcomes after receiving adjuvant ferralium, thereby this study was designed to investigate the relationship between TS and serum iron.OBJECTIVE: To study the relationship between TS and serum iron.SETTING: At a nursing science department of a university-affiliated hospital, pediatric department of a university affiliated hospital and sectional hospital.PARTICIPANTS: Between June 1997 and December 2000, 45 children with TS received treatment at pediatric clinic of Chenghai sectional people' s hospital, Shantou city, who accorded with the diagnostic standards of the second edition of Chinese Psychopathy Category and Diagnostic Standards,those who were confirmed as brain organic diseases by CT and MIR were excluded.METHODS: Serum iron, hemoglobin and the number of red blood cells were determined in 45 TS children and compared with that in 38 controls.MAIN OUTCOME MEASURES: Difference of the level of serum iron and the incidence of hypoironemia between two groups.RESULTS: The level of serum iron was(12.79 ±0.67) μmol/L in experimental group, obviously lower than(19.26 ± 5.38) μmol/L in control.group( P ＜ 0. 005), the incidence of hypoironemia was 42% significantly higher than13% of control group( P ＜ 0. 005).CONCLUSION: Quite a lot of children with TS have hypoironemia that might be one of the pathogenesis factors, the possible mechanism is, as the result of hypoironemia, decreased activity of monoamine oxidase led to abnormal monoamine neurotransmitter.

The ralationship between traditional Chinese medicine (TCM) and intestinal microecology is increasingly being given more and more attention. Combined with the devolopment of intestinal microecology disciplines, effects of TCM on regulation of intestinal microecology have been gradually explained. Both clinical studies and animal experiments have confirmed that TCM can maintain the balance of intestinal microecology and regulate the intestinal flora. The author arrangemented the documents related to Chinese herbal compound adjusting intestinal flora in the recent ten years, summarized that the Chinese herbal compound which can strength spleen and replenish Qi, relax bowels and regulate Qi, dissipate dampness and check diarrhea, clear away heat and toxic materials, promote digestion and relieve stasis had certain regulation effects on intestinal microecology, providing basis for revealing the TCM essence of intestinal microecology.

Background Posterior capsular opacification (PCO) following the extracapsular extract of cataract is associated with the proliferation and migration of residual lens epithelial cells (LECs).Study showed that the incidence of PCO is higher in diabetic patients than those of non-diabetes.So if insulin-like growth factor-1 (IGF-1) participates in the pathogenesis of PCO deserve research.Objective This study was to explore the active mechanism of IGF-1/IGF-1 receptor (IGF-1 R) system in the migration of LECs and offer theoretical basis for clinical prevention and treatment of PCO.Methods Human lens epithelial cell lines (HLEC-B3) were cultured and passaged in DMEM.The cells were identified using fluorescence immunocytometry.IGF-1 with the concentrations of 0,30,90 μg/L were added into the medium separately for 48 hours.The numbers of migrated cells were calculated by Transwell test.The cells were cultured in DMEM containing 0,1.5,30,60,90 μg/L IGF-1,and the expressions of IGF-1 Rα and IGF-1Rβ in the cells were assayed and compared by Western bolt.Results The cultured showed the positive response for α-crystallin anibody with red fluorescence in the cellular membrane.Twelve hours after Transwell incubation,the number of migrated cells (Median) was 0(0,1),10(10,11) and 29(27,31) in the 0 μg/L IGF-1 group,30 μg/L IGF-1 group and 90 μg/L IGF-1 group,respectively,showing a significant difference among the 3 groups (Z=12.610,P=0.002).The number of migrated cells in the 30 μg/L IGF-1 group and 90 μg/L IGF-1 group was significantly more than that of the 0 μg/L IGF-1 group (both at P =0.008),and the number of migrated cells in the 90 μg/L IGF-1 group was significantly more than that of the 30 μg/L IGF-1group (P =0.009).Western blot assay showed that the expressions of IGF-1Rα and IGF-1Rβ in the cells were significantly different among the 0,1.5,30,60,90 μg/L IGF-1 groups (F=63.700,130.530,both P =0.000).The expressions of IGF-1 Rα and IGF-1Rβ were gradually elevated as increase of IGF-1 doses when then concentration of IGF-1 was ＞ 30 μg/L,with significant differences among the different concentrations groups (all at P＜0.05).Conclusions IGF-1 can upregulate the expressions of IGF-1R in HLEC-B3 cells in vitro in a dose-dependent manner.Also,IGF-1 enhances the migration ability of HLEC-B3 cells.These results suggest that activation of IGF-1/IGF-1R system may be associated with the pathogenesis of PCO.

Human immunodeficiency virus (HIV) infection can cause variable movement disorders, including parkinsonism. HIV-related parkinsonism usually responds well to highly-active antiretroviral therapy (HAART), suggesting a possible reversible dysfunction of the dopaminergic system. We report the case of a 42-year-old man who presented with rapidly progressive symmetric parkinsonism, cognitive decline, and loss of postural reflex as the initial manifestation of HIV infection. A significant improvement of his parkinsonism after HAART demonstrates a potentially reversible dopaminergic system dysfunction secondary to HIV infection. A normal 99mTc-TRODAT-1 SPECT image after HAART treatment paralleled the clinical improvement in extrapyramidal symptoms. Early identification of HIV-related parkinsonism, especially in patients with symmetrical akinetic-rigidity and early loss of posture reflex, is important for its potential reversibility with HAART therapy.

Objective To assess the association between Toll-like receptor 9 (TLR9) gene single nucleotide polymorphisms (SNPs) and systemic lupus erythematosus (SLE) development in Guangxi Zhuang and Han populations,as well as the difference in TLR9 SNPs between the two populations.Methods Totally,41 SLE patients of Zhuang nationality and 56 of Han nationality,as well as 82 healthy checkup examinees of Zhuang nationality and 120 of Han nationality were enrolled in this study.Venous blood samples were obtained from all of these subjects and subjected to DNA extraction.The single nucleotide polymorphisms in TLR9 gene were detected by PCR-restriction fragment length polymorphism (PCR-RFLP) analysis followed by direct sequencing.Chi-square test and adjusted Chi-square test were conducted to assess the relationship between the genotype and allele frequencies of TLR9 SNPs and some clinical and laboratory parameters of patients with SLE,as well as the differences in genotype and allele frequencies of TLR9 SNPs between the two populations.Results The frequencies of CC,CT and TT genotypes of TLR9 SNP rs352140 were 42.9％,41.1％ and 16.1％ respectively in the patients of Han nationality,compared to 38.3％,55.8％ and 5.8％ in the healthy controls of Han nationality (all P ＜ 0.05),but no significant difference was observed in the frequency of C or T allele of the SNP rs352140 between the patients and controls of Han nationality (both P ＞ 0.05).There was no significant difference in the genotype or allele frequency of TLR9 SNP rs352140 between the patients and healthy controls of Zhuang nationality,or between the patients of Han nationality and Zhuang nationality (all P ＞ 0.05).The patients with anti-dsDNA antibodies showed a significantly higher frequency of TT genotype (P ＜ 0.05),but similar T allele frequency at TLR9 SNP rs352140 (P ＞ 0.05) compared with those without.The frequencies of both TT genotype and T allele of TLR9 SNP rs352140 were significantly increased in the patients with a SLE disease activity index (SLEDAI) ≥ 9 compared with those with a SLEDAI ＜ 9 (both P ＜ 0.05).There was no statistical difference in either the TT genotype or the T allele frequency at TLR9 SNP rs352140 between antinuclear antibody-positive and-negative patients with SLE (both P ＞ 0.05).Conclusions The TLR9 SNP rs352140 is correlated with several clinical and laboratory parameters of SLE,and might contribute to the susceptibility to SLE in Guangxi Han population.

Objective To analyze the features of EMU survived casualties and the rescue during a head -on- rear collision between two EMU trains on 23 July 2011 ( July 23 train collision accident) at Wenzhou station.Methods The casualties treated in many major hospitals in Wenzhou were surveyed within 24 hours after the accident occurred.The data of age,gender,type of injury and injury severity of the wounded were analyzed.Results A total of 136 casualties were treated within the first 24 hours after the accident occurred,and the male patients and female patients accounted for 55.89％ and 44.11％ respectively,blunt trauma was the main cause of injuries.The percent of multiple injuries in the wounded survivals accounted for 79.41％.The most common injury site of the survived casualties was chest,followed by four limbs and spine.All the wounded were rescued on the spot and were referred to the hospitals with better medical facilities.Conclusions There was no significant difference in gender of the wounded.Blunt trauma was the leading cause of injuries,and the chest,four limbs and spine were the liable parts of body to be traumatized.Saving life,triaging and transferring the wounded as soon as possible were the major algorithm during the initial stage of medical rescue after the accident occurred.
