? AIM: To analyze clinical characteristics and postoperative outcomes after open globe injury.?METHODS: Demographic characteristics ( age, gender, eye trauma, profession, cause of injury and injured part ) , as well as complications and prognosis were analyzed in 152 cases (152 eyes) of open globe injury.? RESULTS: Patients with open globe injury had an average age of 40. 45±38. 32 years old with a 5. 9:1 male-to-female gender ratio. The left-to-right eye ratio was 1. 27:1. Most patients were workers, farmers, or retired. The most common etiologies were scratches, boxing, and falls. Zone Ⅲ was the most commonly injured part. Iridoptosis or iris incarceration, retinal detachment, vitreal prolapse, hyphema or hypopyon, and vitreous hemorrhage were the most common complications. Visual acuity improved in 86 cases postoperatively but ophthalmectomy was still required in 25 eyes.?CONCLUSION: Vision can be improved after surgery in open globe injury. However, patients are usually seriously injured and improvement is minimal, thereby resulting in a great loss to patients and society.

It was widely believed that the interaction between rice and rice blast fungus can be interpreted by the gene-for-gene hypothesis. Two interaction models between rice blast fungus and anti-disease genes had been briefed. They were receptor-ligand model and guard model. The progress of research about molecular marker and position on avirulence genes of the pathogens of rice blast (Magnaporthe oryzae) was reviewed, and the methods to clone and the cloned avirulence genes of rice blast fungus were also summarized.

Objective To explore the change of plasma orexin A concentration and the correlation between plasma orexin A concentration and energy intake in obese children.Methods Fasting plasma orexin A concentrations,boaly mass index(BMI) and energy intake were measured in 48 obese children(obese group) and 48 healthy children(healthy control group),and these indexes were compared,the correlation between plasma orexin A concentration and BMI,energy intake were analyzed.Results 1.The plasma orexin A concentration in obese group was significantly lower than that in healthy control group(F=5.632 P=0.008).2.In obsess group,there were negative correlation between plasma orexin A concentration and BMI(r=-0.478 P=0.012),positive correlation between plasma orexin A concentration and total energy intake(r=0.503 P=0.007),fat intake(r=0.659 P=0.006) and protein intake(r=0.381 P=0.026),and there was negative correlation between plasma orexin A concentration and carbohydrate(r=-0.316 P=0.022).3.In healthy control group,there were negative correlation between plasma orexin A concentration and BMI(r=-0.491 P=0.018),positive correlation between plasma orexin A concentration and total energy intake(r=0.512 P=0.009),fat intake(r=0.406 P=0.005),protein intake(r=0.313 P=0.020),and carbohydrate(r=0.432 P=0.025).Conclusions Orexin A may be involved in regulation of energy metabolism in obese children,and the interaction between plasma orexin A and energy intake might be different in different nutritional status in children.

Objective To compare the sensitivity of fluorescent quantitation polymerase chain reaction (fluorescent quantitation method) and gene‐chips typing method(gene‐chips method) in the detection of human papillomavirus(HPV) ,and to analyse differ‐ences and clinical significance .Methods A total of 246 women were selected as subjects ,among them ,111 cases of cervical exfolia‐ted cells and 135 cases of cervical tissues were collected and detected .15 kinds of high‐risk HPV genetypes were detected in all sub‐jects by using fluorescent quantitation method and gene‐chips method respectively ,and the detection results were compared . Results The sensitivity of the fluorescent quantitation method in detecting HPV was 55 .28% and that of the gene‐chips method was 55 .69% ,there was no statistically significant difference in sensitivity between the two methods (P>0 .05) .The two methods had relative high conformance(κ=0 .745) .The positive rate of HPV infection was increased with the progression of cervical dis‐ease .Conclusion The fluorescent quantitation method and the gene‐chips method have a relative high conformance ,and both with high sensitivity in detecting HPV .The severity degree of cervical cytological and histological changes may be positively correlated with HPV infection .

Objective To investigate the expression of Nogo-66 receptor (NgR) in primary cultured rat astrocytes.Methods RT-PCR and Western blot were applied to verify mRNA and protein expression of NgR in primary cultured and purified astrocytes. Indirect immunofluorensence and confocal microscopic technique were used to study the distribution of NgR. Results Specific NgR cDNA product could be amplified from the total RNA of primary cultured astrocytes by RTPCR; Western blot of the extracts of astrocytes demonstrated a specific NgR band at about 64 kD. Indirect immunofluorescence and confocal scanning further revealed the intracellular localization of NgR protein in astrocytes. Simultaneously,the NgR protein was detected in C6 rat glioma cells by western blot and immunofluoresence staining. Conclusion NgR is expressed in primary cultured astrocytes, which offers strong and direct support for the expression of NgR in astrocytes in vivo.

OBJECTIVETo evaluate the effect of the preadjusted appliance (Z1 appliance) based on Chinese normal occlusion.
METHODSThirty non-extraction patients were treated with Z1 appliance. No wire bending was made during treatment. The results of these 30 cases had been evaluated by five senior orthodontists. Models were analysed quantitatively to testify and evaluate the efficiency of the appliance.
RESULTSThe average score for post-treatment models was 91.2 (total score was 100). The model measurements indicated that average projective distance on occlusal plane between proximal contact points of adjacent teeth was less than 0.3 mm, which demonstrated good alignment. The prominence of crowns was almost coincident with the data of Chinese normal occlusion. For the average tip of most teeth, there was no statistical difference between the study group and the normal control group. The crown torque variation tendency from anterior to posterior was similar to that in the subjects with normal occlusion. However, the cases treated with Z1 appliance achieved more negative torque in the lower posterior segment.
CONCLUSIONSThe result of the non-extraction patients treated with Z1 appliance was quite satisfied. Wire bending could be reduced during treatment. It was necessary to adjust the crown torque values for lower posterior teeth.
