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.

AIM: To investigate the effect of rigid contact lens in the treatment after pterygium excision and limbal stem cell transplantation in senile patients.METHODS: Totally 90 elderly patients diagnosed as unilateral pterygium in our hospital from March 2015 to March 2016 were selected and divided into two groups, observation group and control group, 45 case with 45 eyes in each group.Observation group was treated with limbal stem cell transplantation and rigid contact lens.Control group was treated with limbal stem cell transplantation only.The following indicators were observed and compared: corneal healing time, visual analogue score(VAS) at 1, 3, 5 and 7d after surgery and the recurrence rate of pterygium.RESULTS: The score on corneal irritation of observation group was significantly lower than that of control group (P<0.05).Control group took more time on corneal healing than observation group (P<0.05).VAS of control group were higher than that of the observation group at 1 and 2d after treatment with significant difference (P<0.05).The recurrence rates of pterygium were not statistically significant between the two groups (P>0.05).CONCLUSION: Autologous corneal stem cell transplantation combined with rigid contact lens for pterygium in elderly patients is effective with shorter healing time and less pain, and it does not increase the recurrence rate.

Farnesoid X receptor (FXR) belongs to the nuclear receptor superfamily. It is highly related to the formation of metabolic syndrome and the glucose homeostasis, and therefore represents an important drug target against metabolic diseases and diabetes. In recent years, great progress has been made in the agonists, antagonists, and crystal structures of FXR. The diverse FXR ligands and their structure-activity relationship are reviewed in this article. The advances in the crystal structures of FXR in complex with different ligands are also introduced.

Objective To explore clinical features and drug sensitivity of Streptococcus pneumoniae (SP) isolated from pediatric patients with lower respiratory tract infection, and to provide evidence for clinical use of antibiotics. Methods A total of 6 358 clinical SP isolates from children with lower respiratory tract infection from January 2008 to December 2012 were col-lected and retrospectively analyzed. The antibiotic sensitivity was done by Kirby-Bauer method and E-test, and all results were in strict accordance with the rules of CLSI. Results The isolated SP strains were mainly from different departments of pediatrics. All clinical cases with SP infection mainly included pneumonia and bronchitis. The resistance rates of 6 358 SP strains to penicil-lin, cefotaxime, erythromycin, clindamycin, cotrimoxazole, tetracycline, chloramphenicol, levolfoxacin, vancomycin were 5.0%, 12.9%, 98.7%, 96.0%, 92.2%, 7.3%, 5.6%, 0.2%and 0.0%respectively, and the resistance rate to penicillin and cefotaxime was signiifcantly different in every years (all P<0.05). The resistance rates of the 318 penicillin-resistant SP strains to the above anti-biotics were 100.0%, 42.6%, 100.0%, 100.0%, 99.2%, 23.6%, 6.8%, 0.6%, 0.0%respectively, and the resistance rate to penicillin and cefotaxime was signiifcantly different (P=0.001). Conclusions The antibiotic resistance rates of SP strains isolated from children with lower respiratory tract infection were higher to erythromycin, clindamycin, cotrimoxazole and tetracycline, and an increasing rate in drug resistance to cefotaxime was observed in recent years. Appropriate antibiotics should be selected for the treatment of infection according to drug sensitivity.

BACKGROUND:Tooth wear is the physiological change that accompanied by a person’s life, type and nature, maxil ary and mandibular occlusion status, physical status, and living environment may affect it.
OBJECTIVE:To review the occurrence and development of tooth wear, as wel as research on the morphology of wear surface.
METHODS:The PubMed database was searched by the first author for the articles from January 1952 to
December 2012. The articles on the generation of tooth wear facets, macroscopic and microscopic studies of occlusal wear facets, wear measurement method, relationship between tooth wear and oral diseases, and
application of tooth wear facets in forensic research were included. The key words were“tooth, wear, diet,
information, dentistry, anthropology”in English. A total of 59 articles were included according to the inclusion criteria for review.
RESUTLS AND CONCLUSION:With the development of wearing, some oral clinical symptoms may occur. Just as there are no same fingerprints in the world, the individual tooth wear facet is unique. Therefore, the research on occlusal wear facets has great significance for understanding the diet habits, cultural development, age and other information, as wel as for dentistry, anthropology and forensic science. The macroscopic and microscopic study of tooth wear surface can provide a large amount of individual information. The current studies on tooth wear facets cannot ful y exhibit al the implicated information, so the further studies are needed.

Objective To make a bioinformatical analysis of the specific allergen pTSX1 cDNA clone obtained from Humulus pollen in allergic asthma by immunological screening and gene cloning. Methods Bioinformatical approaches, including sequence analysis, sequence alignment, genetic makeup, protein structure and function prediction, were used. Results The analysis of the specific allergen pTSX1 cDNA showed that the gene had no reading frame and coded a protein with 204 amine acids. The analysis of amine acids sequence coded by the pTSX1 cDNA showed that the protein identity of this gene product might be one of ribosomal proteins. Conclusion The pTSX1 cDNA cloned from Humulus pollen in allergic asthma is a new gene, and the protein coded by pTSX1 gene may be one of ribosomal proteins.

Objective To investigate effects of Naoxintong drip pill (NDP) in activating blood and removing blood-stasis and on myocardial and cerebral ischemia. Methods The in-vivo effect of NDP on thrombosis, aggregation of platelets, blood viscosity, microcirculation, acute myocardial and cerebral ischmia and the focal cerebral-infarction were observed for study the pharmacodyamic effect of NDP. Results NDP could significantly inhibit the formation of thrombosis and maximal aggregation rate of platelets, and decrease viscosity in whole blood and plasma in rats with blood stasis. It could also promote auricular microcirculation, prolong the survival time of mice with cerebral ischemia, improve the electrocardiogram of ischemic rats, reduce the focal cerebral-infarction area and improve behavior disorder. Conclusion NDP possesses actions of activating blood and removing blood-stasis and improving myocardial and cerebral ischemia and focal cerebral-infarction.

Objective To construct humulus scandens pollen major allergen DNA vaccine pcDNA-LC2 and evaluate its immunogenicity. Methods Humulus scandens pollen allergen gene was digested from recombinant plasmid pTripIEx2-LC2 by EcoRⅠ and HindⅢ of restriction endonuclease, and then inserted into expression vector pcDNA3.1(-). A large amount of endotoxin pcDNA3.1-LC2 purified plasmid was extracted after successful construction, and animal experiment was carried out to study its immunocompetence. Results Sequencing results showed that 672bp in the coding sequence of frames of recombinant pcDNA3.1-LC2 was in line with the original base line, without deletion or mutation. pcDNA3.1-LC2 of pollen allergen humulus scandens allergen vaccinated BALB/c mice. Double immunodiffusion test showed that pcDNA3.1-LC2 could be expressed and produce antibodies in mice. Conclusion Humulus scandens grass pollen major allergen DNA vaccine pcDNA3.1-LC2 has been successfully constructed. It can be expressed in mice, produces humulus scandens grass pollen allergen specific antibody and has a good immunogenicity.
