AIM: To investigate the clinical features of acquired immune deficiency syndrome ( AIDS) patients associated ocular diseases in Urumqi and the relationship between ocular fundus manifestations and CD4+T cell count.
METHODS: The fundus of 93 AIDS patients were examined by indirect ophthalmoscopy. The clinical symptoms and CD4+T cell count of those patients with fundus changes were analyzed.
RESULTS: Thirteen patients were found having fundus changes which occurred in one eye of 4 patients and two eyes of 9 patients, respectively, and the total detection rate was 14. 0%. Seven patients had vision changes, and the main clinical features of retinal lesion were cotton wool spot and hemorrhage of retina. Four patients were diagnosed as retinitis with cytomegalovirus ( CMV ) infection and 9 patients were diagnosed as HIV related retinopathy diseases. Seven patients among 37 patients with CD4+T cell count ≤100cell/μL had fundus changes related AIDS, and the detection rate was 18. 9%; while 6 patients among 56 patients with CD4+T cell count >100cell/μL had fundus changes related AIDS, and the detection rate was 10. 7%. There was statistical difference between the two detection rates (P<0. 05).
CONCLUSION: No specificity was found of those patients with the clinical manifestation of HIV- related retinopathy, and those patients are easy to be missed diagnosis. A number of AIDS patients have fundus changes without any vision changes. Therefore, it is very useful for AIDS patients to be carried out the routine fundus examination for the early diagnosis and treatment.

Objective To investigate the value of the cold supernatant in the clinical practice. Methods 25 cases of TTP got a direct infusion of cold supernatant or plasma exchange using cold supernatant as fluid replacement and with medications at the same time. Then we observed the clinical treatment effect of all the cases. Results The clinical remission rate of 25 cases of TTP was 80%. Conclusion The cold supernatant could be used as a new blood component in clinical application,especially for the treatment of thrombotic microangiopathy (TMA). It not only can save valuable blood resources,but also can reduce the economic costs of patients.

Objective: PS128 is a novel psycho biotic strain, it has been reported to play an important role in neuropsychiatric disorders. This study investigated the clinical effect of PS128 supplementation on patients with anxiety. Methods: A total of 200 patients with anxiety were recruited, and divided into two groups (n = 100/group). The control group received oral treatment with citalopram, and the PS128 group received PS128 capsules based on citalopram treatment. Hamilton Anxiety Scale (HAMA) and Self-Rating Anxiety Scale (SAS) were used to evaluate the anxiety levels.After 2 months of continuous administration, clinical efficacy was evaluated according to HAMA score. Results: There was no significant difference in HAMA and SAS scores between the two groups before treatment. With the treatment prolonged, the HAMA and SAS score decreased gradually in both control and PS128 groups, and the decrease rate of PS128 group was significantly greater than that of the control group. The clinical effective rates of PS128 group were higher than those in the control group, high levels of clinical cure rate were also detected in the PS128 group. Compared with the control group (22%), the incidence of adverse reactions was significantly reduced for patients in the PS128 group (4%). Conclusion The treatment effect of citalopram combined with PS128 against anxiety is satisfactory clinically. It can greatly improve the anxiety symptoms of patients, increase the cure rate, reduce adverse reactions.

Objective To investigate the genotypes of host killing genes and their single nucleotide polymorphisms (SNPs). Methods Three hundred and twenty strains of Escherichia coli that collected from the First Affiliated Hospital of Wenzhou Medical College were analyzed. The first sample ( E1 ) contains 160 strains isolated during the years from 2002 to 2003. The second sample (E2) contains 160 strains covering the years from 2008 to 2009. The plasmids of Escherichia coli were extracted by alkaline lysis method. Solexa/Illumina sequencing technology was used to sequence plasmids metagenome. Solexa Genome Analysis System and Soap programs were used to analyze gene distribution, SNPs and lineage-specific mutations. Results 11 077 768 reads were generated and 0. 045% of them can map to the reference sequences from El sample. Whereas 9 377 792 reads were generated and 0. 053% of which mapped to the reference from E2 sample. There are nine host killing genes identified in the two samples, of which hok gene is the most prevalent. A total of 29 SNP sites dispersed in five genes of the two samples. Approximately 33% of them were non-synonymous mutations. One position of A and G is the most prevalent polymorphism. Conclusion The known nine genotypes of host killing genes were all identified in plasmids of Escherichia coli in Wenzhou. hok gene showed the highest frequency. There were SNPs in five genotypes.
