Objective　To investigate the causes of recurrent spontaneous abortion(RSA) and to know the relation between RSA and antiphospholipid thrombosis syndrome(APL-T). Methods　ELISA and PTT-LA were used to detect anticardiolipin antibody(ACA) and lupus anticoagulant(LA) in 32 patients with RSA and 20 normal controls(NC). Results　There were 17 positive of antiphospholipid antibody(APA) in RSA group. The incidence was significantly higher than that in NC group. The incidence of LA was also significantly higher than that in NC group. 8 patients were diagnosed as APL-T. Conclusion　LA may be the more important reason of RSA. It should be considered as APL-T when RSA is unexplained.

Objective: To view the characteristics and the primary treatment of civilian firearm wound in the maxillofacial region.Methods: 301 cases of the casualties admitted to our hospital were retrospectively investigated,the epidemic, etiology, wound characteristics, and treatments of the patients were viewed respectively. Results: Of all the cases, the ratio of male to female was 5.1∶1.0. 57% of the injuries were caused by gunshot, 66% were with multiple injuries.16% combination wound were craniocerebral injuries. In this group of patients, more than 900 wound tracks were found, 72% of the tracks were nonpenetrating and 67% of those were with foreign bodies lodged in. Burns with blast injuries were the main complex wounds, which mostly occurred in explosion. The treatments mainly included life maintaining, earlier debridement and infection control. Conclusions: The maxillofacial firearm injuries are complex and have their own characteristics depending on the firearms, the wound styles and the regional anatomy. All the factors must be considered when treatment is given.

Tear fluid is a complex body fluid,which may contain thousands of protein/peptides and other molecules.Studies have determined that the changes in the chemical compositions of tears play an important role in some diseases and their progression.Tear fluid is a useful and easily accessible source for understanding ocular surface diseases,other eye diseases,and systemic diseases.It can also be used for identification of biomarkers for clinical applications and pharmaceutical development.Therefore,quantitative proteomic analysis of tears may provide very important information for diagnosis and treatment of eye diseases or the development of new drugs.Knowledge of the current proteomic technologies for tear analysis is helpful for conducting studies.In addition,ophthalmologists should pay close attentions to the association between tear proteomic changes and eye diseases,recent advances in tear proteomics and their applications in studying ocular surface diseases and conditions.

Previous research demonstrated that human tear is a valuable source for biomarker discovery for many ocular surface diseases.Here, we systematically summarized the changes of tear protein profile in many ocular surface diseases, including dry eye, blepharitis, ocular allergy, keratoconus, infectious keratitis, conjunctivochalasis, ocular rosacea, and thyroid-associated ophthalmopathy and other conditions, such as diabetes, ocular surface wounding and refractive surgeries, contact lens wearing, and effects of glaucoma medication on ocular surface, attempting to make ophthalmologists understand the specific changes of tear protein profile in each disease or condition and hold the promise for optimal management of the diseases.

Objective To investigate the clinical value of 64 slice spiral CT low dose chest scan in the diagnosis of pulmonary tuberculosis.Methods From January 2015 to January 2016,45 patients with suspected pulmonary tuberculosis were studied.All patients underwent routine chest CT scan and low dose chest CT scan.To compare the difference of radiation dose related parameters between normal dose chest CT scanning and low dose chest CT scan.To observe the display of the characteristics of lung disease by routine dose chest CT scanning and low dose chest CT scan.Results In 45 patients,there were a total of 30 patients were diagnosed with tuberculosis.The diagnostic sensitivity,specificity and diagnostic coincidence rate of conventional CT scan and spiral CT low-dose scan were 93.3% and 86.7% respectively.In low dose CT scanning radiation dose related parameters,the effective dose [(1.36±0.22)mSv vs.(5.24±0.68) mSv],CT dose index[(31.8±3.7) vs.(51.2±6.3)] and dose length product[(35.4±5.4)mGycm vs.(137.9±26.1) mGycm]were significantly lower than those of the conventional dose CT scan,the differences were statistically significant (all P<0.05).Conventional dose and low dose CT scan could show the lung lesions of pulmonary tuberculosis.Comparison between the two groups,low dose CT scanning on the burr sign and grinding glass shadow display rate was low.Compared with the conventional dose CT scanning,the difference was statistically significant (P<0.05).Conclusion In the diagnosis of pulmonary tuberculosis,the radiation dose of 64 slice spiral CT is significantly decreased,be able to clear most of the lung lesions.However,the effect is poor in the display of the grinding glass and the thin and short burr.

Objective To investigate the effect and safety of Atropine preparations of 0.1%and 0.01%concentrations in the treatment of Ametropia.Methods 123 cases of ametropia from April 2014 to August 2015 in ophthalmic hospital of ningbo were randomly selected and divided into three groups, 41 cases in each group.High concentration group received 0.1%atropine sulfate eye drops treatment,low concentration group received 0.01%atropine sulfate eye drops treatment,and the control group received artificial tear mytear,and three groups were treated for one year.Changes in vision, refraction, intraocular pressure and axial length of the eye were compared after the treatment.Results High concentration group >low concentration group >control group in the the difference of distant visual acuity before and after the treatment ( P<0.05 ) , control group >low concentration group>high concentration group in the refractive index,intraocular pressure and ocular axis length difference before and after treatment (P<0.05),and the effective rate in the low concentration group 85.37%and high concentration group 90.24%had no significant difference.Adverse effects rate in high concentration group was 21.95%which was higher than low concentration group 4.88%(P<0.05).Conclusion 0.1%and 0.01%concentrations of atropine were effective control of Ametropia in flexion and axial length spectrophotometry, and then improve the visual acuity, and the former is better,but the 0.01%concentrations had higher safety.

Objective To explore the effects of noise exposure on acoustic reflex growth function (ARGF).Methods 106 ears of 57 industrial workers that exposed to high level continuous noise during their work day were divided into three groups according to pure-tone threshold average (PTA): normal hearing group, mild hearing loss group and moderately severe hearing loss group. The control group consisted of 50 ears of 25 young persons with normal hearing. The contralateral acoustic reflex thresholds (ART) were obtained from all individuals.1 000 Hz pure-tone stimuli was wsed to elicit the acoustic reflex at hearing levels from ART to 125 dB in 5 dB steps during ascending intensity level runs. The growth functions were observed as changes in acoustic reactance with increases in activator-signal intensity level.Results The noise exposed groups had smaller acoustic reflex dynamic ranges, smaller acoustic reactance growth magnitudes and shallow slopes compared with those of the control group. Data showed that there were significant differences among the control and the noise exposed groups (P0.05).Conclusion The influence of noise exposure on ARGF is significant. The results of this study suggest that ARGF could be used in the monitoring of the noise-induced hearing loss as an indicator of subtle alterations of the hearing function.
