? 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.

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.

The whole herb of Solanum nigrum L. can be used as the herbal drug. In this study, UHPLC-Q Exactive high resolution mass combined with GNPS molecular network was used for the rapid characterization of the components in the leaves of S. nigrum L. A total of 157 compounds were identified, including 30 steroid alkaloids, 61 steroid saponins, 35 flavonoids, and 31 other compounds (amino acids and organic acids), by comparison with the data reported in the literature, and mass fragmentation characteristics analysis, as well as the correlation of known and unknown nodes in the GNPS molecular network. Compared with the fruits and stems, the leaves of S. nigrum L was rich in a variety of steroidal saponins, steroidal alkaloids, and flavonoids, and the results lay the foundation for the precise resources utilization of S. nigrum L.

Objective To study the distribution status and clinical significance of human papillomavirus(HPV) infection geno‐types in condyloma acuminate(CA) tissues of vulva ,vagina and cervix .Methods The gene‐chips combined with polymerase chain reaction (PCR) technology were utilized for detecting 23 kinds of HPV genotypes in tissue specimens from 63 cases of vulval CA , 61 cases of vaginal CA and 65 cases of cervical CA .Their clinical pathological data were analyzed .Results In 63 cases of vulval CA ,56 cases were HPV positive with the HPV infection rate of 88 .89% (56/63) ,in 61 cases of vaginal CA ,55 cases were HPV positive with the HPV infection rate of 90 .16% (55/61) ,and in 65 cases of cervical CA ,62 cases were HPV positive with the HPV infection rate of 95 .39% (62/65) .Conclusion HPV infection is closely related to the CA pathgenesis in vulva ,vagina and cervix . HPV6 and HPV 11 are main stream genotypes ,in which vulval CA is most common .The gene‐chips combined with PCR technology is a method suitable for HPV typing diagnosis ,and has the characteristics of good sensitivity and high specificity ,which has an im‐portant significance for clinical diagnosis ,treatment and vaccine study of CA in femal vulva ,vagina and cervix .

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 .

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 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.

Objective To explore microbic distribution feature of acute rhinitis pafienta' nasal cavity and dependabihty research of respiratory infection.Methods 436 acute rhinitis pafienta were randomly divided tO infection group(314)and non-infection group(122)depended on whether accompanying respiratory infection.Take blenna narium and carry out nasal cavity microbiological detection,meanwhile take blood and mesasure the content of serum IL-4 and IFN-γ.Results The staphylococcus aureus taked the most proportion(58.6%and 3 1.2%)of nasal cavity bacterial distribution in infection group and non-infection group,the following bacterium were the staphylococcus epidermidis(44.9%and 46.7%),bacillus meningitidis purulentae(7.9%and 4.9%)and bacillus coli(3.5%and 1.6%),the major eumycete were the peptostreptococcus asaeeharolyticus(1.9%and 1.6%),eubacterium lentum (1.6%and 0)and eubacterium mucus(0.9%and 0.8%),the major virus were the syncytial virus,the rhinoviru8es,adenodrus,influenza virus,parainfluenze virus and coronaviruses.The respiratory tract infection patients' content of serum IL-4 Were significant higher(P＜0.05)than the non-infection group,but the content ofIFN-γ were signifieanfly reduced(P＜0.05).Conclusion The staphylococcus aureus,syncytial virus,rhinoviruses,adenovirus and influenza virus have the close relation with the infection of the respiratory tract,which can cause the disorder of organism immune function.
