AIM: To analyze and summarize the effect of glaucoma trabeculectomy in the department of ophthalmology in basic hospital.
METHODS: Postoperative intraocular pressure ( IOP ) , filtering bleb and complications of 316 cases (405 eyes) of patients with glaucoma after trabeculectomy were analyzed.
RESULTS: After follow- up 12mo, 76. 5% IOP was controlled in normal level. 42. 5% was filtration bleb typeⅠ, 33. 1% typeII, 14. 6% in typeⅢand 9. 9% in typeⅣ. Intraoperative complication rate was 2. 5%, that was 31.4% at postoperative early stage ( before discharge ) , and 6. 7% at postoperative long - term ( 6mo after discharge) .
CONCLUSION:Trabeculectomy for glaucoma can better solve the problem of high IOP. It is more mature in primary hospitals, but there are still a variety of intraoperative and postoperative complications.

AIMTo study the effect of hyaluronic acid chitosan-based microemulsion (HAC-ME) on the permeability of blood brain barrier( BBB) by using Evans blue (EB) as the indicator.

METHODSA formamide extraction-ultraviolet spectrophotometry method was employed to determine the concentrations of EB in each of the tissues. The in vivo distribution of HAC-ME groups containing EB in mice and the fluorescence intensity and diffusion domain of brain slices were all studied.

RESULTSContrasting to the common microemulsion (ME), HAC-ME at the lower concentration of HAC (<5 mg x mL(-1)) could further improve the transporting of EB across the BBB while EB concentration in other tissues decreased, and Tmax was delayed about 30 min.

CONCLUSIONHAC-ME could facilitate the transporting of EB across the BBB and it was concentration dependent. While the brain targeting absorptive capability of HAC-ME was enhanced.

flow cytometry.A strong linear relationship was observed in the standard curve of real-time PCR of each bacteria. Conclusion These three non-culture methods can be used in the quantitative analysis of oral microorganisms.Real-time PCR and laser scanning confocal microscopy are better than the traditional culture-based CFU count,and real-time PCR is the most sensitive method.

Objective To detect the differential gene expression between Streptococcus sobrinus(S.sobrinus) 6715 and its fluoride-resistant strains. Methods The fluoride-resistant strains of S.sobrinus 6715 was induced by increasing the concentration of fluoride step by step.Total RNA of both S.sobrinus 6715 and its fluoride-resistant strains was extracted,mRNA was separated and purificated,and then cDNA was obtained by reversed transcription.Suppression subtractive hybridization(SSH) technology was used to detect the differential gene expression between them.The differential gene expression fragments were cloned and compared with the GenBank by BLAST.Results After comparing with the GenBank by BLAST,it was identified that there were two differential gene expression fragments,fruA and SMU.438c. Conclusion The cDNA subtractive lib of differential gene expression between S.sobrinus 6715 and its fluoride-resistant strains was successfully constructed through SSH,which paves a way for the further study of fluoride-resistant mechanism.

8).The amount of the targeted microorganisms(Streptococcus mutans,Streptococcus sobrinus,Actinomyces viscosus and Actinomyces naeslundii) and the total number of bacterial cells were determined by real-time PCR based on SYBR-Green I fluorescence.Results The percentages of the four targeted bacteria in high-caries group were significantly higher than those in caries-free group(P

Objective To investigate the effects of total flavonoids in Gingko Biloba on glucose and lipid metabolism and liver function in rats with insulin resistance. Methods Forty SD rats were randomly divided into normal control group,model group,total flavonoids in Gingko Biloba group and rosiglitazone group(positive drug control group)(n=10).Models of insulin resistance were established by high glucose and high fat diet in model group,total flavonoids in Gingko Biloba group and rosiglitazone group.After treatment for 12 weeks,serum glucose,serum lipids,and parameters of insulin resistance,liver function and anti-oxidation capability were detected in each group,and histologic observations of liver tissues were conducted with adipose staining. Results The serum glucose,insulin resistance index(HOMA-IR),insulin action index(IAI),serum total cholesterol(TC),triglyceride(TG),liver malondialdehyde(MDA) and serum transaminase activity in total flavonoids in Gingko Biloba group were significantly lower than those in model group(P

Objective To analyze the clinical and pathological characteristics of children with lupus nephritis(LN).Methods Ninety-one children with LN were diagnosed from 1993 to 2005,according to the clinical literature and renal pathology and the data were retrospectively summarized.Results Within the cohort of 91 children,there were 69 females and 22 males(female to male ratio 3.1).Most of the sick children were at the school age ranging from 6.0 to 15.5 years old.Nephrotic syndrome(44.0%) was the most common clinical manifestation.Fifty-nine renal biopsies were performed.Class Ⅳ LN(59.3%) was the most frequent pathological findings."A full-house pattern" on immunofluorescence was found in 72.0% of biopsies.The clinical and pathological manifestations of some children were atypical.There were 3 patients characterized by predominant deposits of immunoglobulin M(IgM),1 patient with predominant deposits of IgA,and 2 children with pauci-immune LN.Three children with class Ⅱ LN in our study presented with nephrotic syndrome.LN was initially controlled by aggressive treatment in 93.7% of thse patients.Relapses of nephritis covered 27.1% of them,mostly caused by the intermittent treatment.Conclusions The clinical and pathological manifestations of LN were variable.Some atypical LN was considered to be associated with the distinct pathogenesis.Most of LN could be controlled by aggressive treatment.Long and regular treatment is necessary to improve the prognosis of LN.

OBJECTIVE To define the regularity of survival ability of HIV in natural environment,and prevent(infection) through contacting with positive body fluids during daily life or medical work.METHODS Having been diluted by sterile water or 10% serum RPMI 1640 medium,HIV was exposed to 4℃,room temperature(20-26℃) or 37℃ for different period of time.TCID_(50) of these samples was detected.Non-pathological samples were blind passaged for three generations.RESULTS HIV infective ability persisted more than 35 days both in(water) and medium at 4℃;whereas it persisted 7-14 days in water,14-21 days in medium at room temperature and 37℃.CONCLUSIONS HIV has higher resistance in natural environment.To prevent accidental spreading of HIV,HIV positive liquids and contaminants staffs should be treated carefully.
