Chronic prostatitis is a common male disease, and its pathogenesis is not yet clear. Most scholars believe that oxidative stress and immune imbalance are the keys to the occurrence and progression of chronic prostatitis. Currently immunotherapy of chronic prostatitis remains in the exploratory stage. This article relates the active ingredients of 5 Chinese medicinal herbs (total glucosides of paeony, tripterigium wilfordii polglycosidium, curcumin, geniposide, and quercetin) for the treatment of chronic prostatitis and their possible action mechanisms as follows: 1) inhibiting the immune response and activation and proliferation of T-cells, and adjusting the proportion of Th1/Th2 cells; 2) upregulating the expression of Treg and enhancing the patient's tolerability; 3) suppressing the activation of the NF-kB factor, reducing the release of iNOS, and further decreasing the release of NO, IL-2 and other inflammatory cytokines, which contribute to the suppression of the immune response; 4) inhibiting the production of such chemokines as MCP-1 and MIP-1α in order to reduce their induction of inflammatory response. Studies on the immune mechanisms of Chinese medicinal herbs in the treatment of chronic prostatitis are clinically valuable for the development of new drugs for this disease.

4 weeks of arrested embryos.The AAH expression was found to have the similar result as HIF-1?'s.Conclusions The expression level of HIF-1? and AAH in villi of missed abortion patients is much lower than that of normal early pregnant women.HIF-1? and AAH have a function of supporting normal pregnancy,so their low expression may be an important cause of missed abortion.

ObjectiveTo analyze the characteristics of top of the basilar syndrome (TOBS) in clinic and imaging.MethodsData of 31 TOBS cases were analyzed retrospectively.ResultsThe clinical features of TOBS patients were sudden unconsciousness or vertigo and dyskinesia of the limbs, the dismovement of the eyeballs, abnormality of the pupils, partial blindness or cortical blindness, hypesthesia, disturbance of memory and counting. CT and MRI showed multi-infarction included thalami, occipital lobe, cerebellum, midbrain, temporal lobe.ConclusionTOBS can be diagnosed accurately according to clinical features and imaging signs.

In this study, 31 Notopterygium incisum populations were analyzed using ITS sequences to investigate the genetic structure. The results showed that: the ITS region ranged in size from 634 to 635 bp and base composition was with high G + C content of 57.8%. Thirty-one polymorphic sites were detected from 402 sequences of 31 populations of N. incisum, and the proportion of polymorphic sites was 4.88%, in which parsimony informative sites were up to 12. And 31 haplotypes were identified based on these polymorphic sites. Molecular variance analysis (AMOVA) indicated that high genetic differentiation (57%) existed among population, and gene flow was low (N(m) = 0.38) among populations. Phylogenetic relationships of 31 haplotypes were analyzed using NJ method with N. forbesiias an out-group. Phylogenetic analysis showed that 31 haplotypes from different populations mixed together and did not form distinct geographically separated clades.

AIM:To study the visual acuity and refractive status of students pupils and middle school students in Shenzhen, and to provide a scientific basis for the prevention and control of myopia.
METHODS:A cluster sampling method was used to select five primary school students(6 737) and three junior middle school students(1 925) from Shenzhen. The visual acuity, anterior segment, fundus, eye position, and refractive status were measured. Information on associated factors for poor vision were also obtained using a questionaire. The risk factors of poor vision and the rate of myopia between grade or gender were analysed by Chi-square test.
RESULTS:The rate of poor vision was 67. 0%. Female, family history of high myopia, long time of continuous look near, short time of outdoor activities were the main risk factors. The rate of emmetropia, hyperopia, astigmatism and myopia were 15. 1%, 11. 3%, 11. 0% and 62. 6% respectively. Emmetropia, hyperopia and astigmatism incidenece rate decreased with age growing, but myopia incidence rate was increased. There were significant differences between adjacent two grades in myopia(χ2=7. 338-45. 018, P<0. 05 ) except the primary grade six and the junior grade one. There were significant differences between boys ( 61. 0%) and girls ( 65. 5%) in myopia(χ2=17. 180, P<0. 05).
CONCLUSION:The rate of poor vison is pretty high in students of Shenzhen aged between 5 to 16 years old, and myopia is the main reason. The development rate of myopia is increased with age. Early management of myopia may play an important role in controlling poor vision in students.

Objective To investigate the association of platelet activating factor acetylhydrolase(PAF-AH) activity in children with primary nephrotic syndrome(PNS).Methods The plasma PAF-AH activity was measured in 78 children with PNS who were divided into 3 groups:steroid-responsive nephritic,steroid-dependent nephritic,steroid-resistent nephritic,after they had been given steroid for 6 months.The plasma PAF-AH activity were also measured in 60 healthy children at the same age,with spectrophotometric assay,at the ame time,the blood cholesterol was measured.Results The blood cholesterol has positive correlation with the plasma PAF-AH activity,there was no significant difference of the blood cholesterol among 3 groups in nephrotic syndrome children,there was a significant difference in the plasma PAF-AH activity among 3 groups in PNS children,but there was no significant difference in the plasma PAF-AH activity between the groups of steroid-responsive nephritic and healthy children.Conclusion Plasma PAF-AH activity is related to the sensibility to steroid treatment in children′s PNS,and the plasma PAF-AH activity in steroid-resistent nephritic is higher than steroid-dependent nephritic.It is a question that if gene mutation is related with PAF-AH activity.

Objective To release the correlation of point mutation of platelet activating factor acetylhydrolase(PAF-AH)gene and primary nephritic syndrome (PNS).Method According to the effect of hormonal therapy,94 children with PNS were divided into three groups:steroid-sensitive nephritic syndrome(SSNS),steroid-resistent nephritic syndrome(SRNS),steroid-dependent nephritic syndrome(SDNS).The point mutation of PAF-AH gene (G994T) were identified by molecular biology technique in children with PNS and 239 healthy children were set as control group.Results No statistics differences were found relating to the genotype and allele frequencies between patients with PNS,SSNS,SRNS and normal controls.But it is confirmed that the genotype and allele frequencies among patients with nephritic type nephritic syndrome (NTNS)was higher than patients with simple type nephritic syndrome(STNS) and normal controls.SDNS was higher than both SSNS and normal controls.The number of relapses during the first year after onset was significantly higher in the patients who were heterozygous for the mutant allele (GT) or homozygotes (TT) than in those of the GG homozygotes.Conclusion Most PNS children with PAF-AH gene mutation occurred at position 994 were NTNS.The risk of relapse during the treatment period was higher in patients with PAF-AH gene mutation occurred at position 994.

ObjectiveTo study how to diagnose thrombosis of intracranial venous sinus and cerebral venous thrombosis(CVT). Methods6 cases with intracranial venous sinus and CVT were analysed by clinical features and imaging signs. ResultsMost patients had symptoms and signs of intracranial hypertension. Some patients manifested symptoms of whole brain or focal neurological deficits. Magnetic resonance imaging (MRI) and magnetic resonance venography (MRV) play important roles for the diagnosis of intracranial venous sinus and CVT, however, digital subtraction angiography (DSA) is one of the most reliable method for early diagnosis of the above diseases.Conclusions According to clinical features and imaging signs, intracranial venous sinus and CVT could be diagnosed accurately .

Human xanthine oxidase is considered to be a target for therapy of hyperuricemia. Cichorium intybus is a Chinese plant medicine which widely used in Xinjiang against various diseases. In order to screen the inhibitors of xanthine oxidase from C. intybus and to explore main pharmacological actions of cichory a compound collection of C. intybus was built via consulting related references about chemical research on cichory. The three-dimensional crystal structure of xanthine oxidase (PDB code: 1N5X) from Protein Data Bank was downloaded.. Autodock 4.2 was employed to screen the inhibitors of xanthine oxidase from cichory 70 compounds were found to possess quite low binding free energy comparing with TEI (febuxostat). C. intybus contains constituents possessing potential inhibitive activity against xanthine oxidase. It can explain the main pharmacological actions of cichory which can significantly lower the level of serum uric acid.
