Objective To compare the changes of retinal sensitivity of central 30? visual field after correction with spectacles with those before correction in juveniles and to provide data for the necessity of correction with spectacles in the measurement of juvenile central visual field. Methods The changes of the retinal sensitivity of central 30? visual field after correction with spectacles in 122 eyes of juveniles were measured using Humphrev 750 Ⅱ perimeter, and were compared with those before correction. Results All the myopic eyes of 122 juveniles passed the reliability of parameters. Among the detected eyes, 110 eyes showed degree dependent changes of the retinal sensitivity of central visual field. Conclusion Correction with spectacles should be used for the measurement of central visual field in juveniles. Otherwise, the results might be unreliable, especially in the cases with moderate and high myopia.

Objective To explore the clinical therapeutic methods for secondary glaucoma induced by the migration of silicone oil into the anterior chamber.Methods Totally 26 cases of such secondary glaucoma,including 22 aphakic eyes and 4 phakic eyes were subjected.Silicone oil was directly taken out for the patients whose retina was reposited well after silicone oil injection for over 3 months.The aphakic patients underwent 6 o'clock position peripheral iridectomy with laser or operation on prone position,then silicon oil was reinjected,and trabeculectomy was carried out through inferior cornea.The phakic patients received silicone oil aspiration with Healon from the anterior chamber.When silicone oil remigrated into the anterior chamber,the crystal was resected,silicone oil was reinjected,and 6 o'clock position peripheral iridectomy were performed.The patients were followed up for 3 months after the intraocular pressure(IOP) reaching normal range.Results Except one patient gave up treatment,all the patients had stable and normal IOP after 3 months of follow-up.IOP was controlled through different methods in 21 aphakic eyes:5 with prone position,5 with 6'clock position peripheral iridectomy through laser or operation,4 with silicon oil reinjecting,2 with direct aspiration of silicone oil,and 3 with trabeculectomy under cornea.IOP was controled in all of phakic eyes:3 with Healon aspiration of silicone oil,1 with crystal resection and reinjection of silicone oil.Conclusion Secondary glaucoma induced by migration of silicone oil into the anterior chamber can be satisfactorily treated by many ways.

Chinese Physician Declaration and Medical Professionalism in the New Millennium-Physician De-claration in the United States and European countries are two significant documents that promote and cultivate phy-sicians′professionalism. Researches showed that the two declarations were basically the same in the background and guiding ideology. However, influenced by the historical tradition, cultural characteristics, medical and health system, medical science technological development, and social psychological factors, there exists difference in terms of perceive and practice. The differences manifest in the comprehension and grasping, ethnical theory basis, the nature and the degree of standard abilityand practice guarantee of physicians′professionalism. Therefore, study on the differences between the two declarations is beneficial to the construction of physicians′professionalism in our country.

Objective To study the value of using endoscopy iodine staining combined detecting the expression of p53, survivin and telomerase in the diagnosis of early esophageal carcinoma and precancerous lesions. Methods Three hundred patients who received routine gastrescopy and had high risk of esophageal carcinoma were examined by the iodine dyeing on their esophageal mucosa with 2. 5% Lugol solu-tion. Multiple biopsies were taken from the unstained or light-stained areas when their diameters were over 5mm for pathology diagnosis. The expression of p53, survivin and telomerase were detected by immunohistochemical staining. Results With the Lugol staining method, the incidences of light, moderate and high grade dysplasia and early esophageal carcinoma were 16. 3% ,9. 7% ,3.7% and 4. 3% respectively. The expression of p53, survivin and telomerase were related and the unstained were related to the expression of p53, survivin and telomerase in dysplasia and early esophageal carcinoma. Using endoscopy iodine staining combined testing p53, survivin and telomerase showed sensitiv-ity of 100%, specificity of 92. 3% and accuracy of 91.8% to diagnose of early esophageal carcinoma and high grade dysplasia. Conclusion Lugol solution chromoendscopy combined assay of p53, survivin and telomersse might be useful in the diagnosing early esophageal carcino-ma and precancerous lesion.

OBJECTIVETo study the influence of the quorum sensing inhibitor brominated furanone on Porphyromonas gingivalis (P. gingivalis) biofilm formation.

METHODSDoubling dilution method was used to determine the minimal inhibition concentration (MIC) of brominated furanone on P. gingivalis. Absolute ethyl alcohol added in P. gingivalis bacterial suspension was used as the negative control, while P. gingivalis bacterial suspension as blank control. The influences of 1/4MIC, 1/2MIC, MIC, 2MIC of brominated furanone on P. gingivalis biofilm formation were studied by the optical density determination and scanning electron microscope (SEM).

RESULTSFour groups of brominated furanone with different concentrations were shown to inhibit P. gingivalis biofilm formation. With the increased concentration of brominated furanone, optical density of P. gingivalis suspension decreased. The biofilm structures of 1/4MIC group, 1/2MIC group and MIC group were loose. Only scattered P. gingivalis cells but no biofilm structure was seen in 2MIC group.

CONCLUSIONBrominated furanone could inhibit P. gingivalis biofilm formation without the influence on bacterial growth. The future application of this chemical compound may provide a new possibility for the antimicrobial treatment of periodontal disease.

Objective To evaluate the effect of methylprednisolone on endoplasmic reticulum stress in rats with ventilator-induced lung injury ( VILI ) and the relationship with phosphatidylinositol 3-kinase∕serine-threonine protein kinase ( PI3K∕Akt) signaling pathway. Methods One hundred clean-grade male Sprague-Dawley rats, aged 4-5 months, weighing 270-320 g, were divided into 5 groups ( n=20 each) using a random number table method: control group ( C group) , VILI group ( V group) and different doses of methylprednisolone groups ( M1-3 groups) . Group C received no mechanical ventilation and kept spontane-ous breathing for 4 h. Rats were mechanically ventilated ( tidal volume 40 ml∕kg, respiratory rate 15-17 breaths∕min, inspiratory∕expiratory ratio 1 : 1, positive end-expiratory pressure 0, fraction of inspired oxy-gen 21％ during OLV) in group V. Methylprednisolone 2, 10 and 30 mg∕kg were intravenously injected at 20 min before mechanical ventilation in M1-3 groups, respectively, and the equal volume of normal saline was given in group V. Blood samples and lung tissues were taken at 4 h of ventilation for measurement of the lung permeability index ( LPI) and wet∕dry lung weight ratio ( W∕D ratio) , for examination of pathological changes, and for determination of apoptosis index ( AI) in lung tissues ( by TUNEL) , expression of Akt, phosphorylated Akt (p-Akt), glucose-regulated protein 78 (GRP78), CCAAT∕enhancer-binding protein homologous protein (CHOP) and caspase-12 in lung tissues (by Western blot). Injured alveoli rate (IAR) was calculated. Results Compared with group C, the W∕D ratio, LPI, IAR and AI were significantly in-creased, the expression of p-Akt was down-regulated, and the expression of GRP78, CHOP and caspase-12 was up-regulated in V and M1 groups ( P<0. 05) , and no significant change was found in the indexes mentioned above in M2 and M3 groups ( P>0. 05) . Compared with group V, the W∕D ratio, LPI, IAR and AI were significantly decreased, p-Akt expression was up-regulated, and the expression of GRP78, CHOP and caspase-12 was down-regulated in M2 and M3 groups ( P<0. 05) . Conclusion Methylprednisolone in-hibits endoplasmic reticulum stress, thus inhibiting cell apoptosis, and the mechanism is related to activa-ting PI3K∕Akt signaling pathway in rats with VILI.

AIM: To evaluate the efficacy of high-intensity focused ultrasound cyclo plasty(UCP)in the treatment of glaucoma and to investigate related influencing factors.METHODS: The study involved a total of 110 patients(134 eyes)who received UCP treatment between January 2019 and January 2022 at three medical centers: Tianjin Eye Aier Eye Hospital, Chongqing Aier Eye Hospital, and Chongqing Nanping Aier Eye Hospital. Patients were classified into three categories: primary angle-closure glaucoma, primary open-angle glaucoma, and secondary glaucoma. Best corrected visual acuity, intraocular pressure, and the usage of anti-glaucoma medications, etc., were recorded at 6 and 12 mo postoperatively.RESULTS: After 6 months of the UCP procedure, statistically significant differences in intraocular pressure were observed across all groups(all P<0.05). At 12 mo postoperatively, intraocular pressure of the primary angle-closure and primary open-angle glaucoma groups showed differences(all P<0.05). Notably, there were no significant changes in visual acuity at either the 6 or 12 mo compared to preoperative values across all patient groups(all P>0.05). Furthermore, the study identified a statistically significant correlation between the changes in intraocular pressure at 6 mo and factors such as age, history of previous glaucoma surgery, baseline white-to-white(corneal diameter), and the extent of UCP treatment(all P<0.05).CONCLUSION: The UCP procedure has been demonstrated to effectively lower intraocular pressure in patients with glaucoma. The efficacy appears to be influenced by variables including patient age, previous glaucoma surgery history, baseline white-to-white(corneal diameter), and the scope of UCP treatment. Importantly, UCP treatment did not adversely affect visual acuity, underscoring its favorable safety profile.
