ABSTRACT
AIM: To investigate the clinical efficacy and safety of ultrasonic ciliary plasty(UCP)combined with injection of anti-vascular endothelial growth factor(VEGF)in the treatment of neovascular glaucoma(NVG).METHODS: A total of 30 NVG patients(30 eyes)admitted to the First Affiliated Hospital of Bengbu Medical College from September 2020 to September 2021 were selected. After admission, all the eyes of the patients were injected with anti-VEGF drug(ranibizumab). After surgery, 15 patients were randomly selected for UCP treatment(UCP group), and the other 15 patients received trabeculectomy(trabeculectomy group). During the 10mo postoperative follow-up, the decrease of intraocular pressure was compared between the two groups and the changes of the degree of ocular pain and the occurrence of related complications were evaluated at each follow-up visit.RESULTS: The intraocular pressure and pain degree of the UCP and trabeculectomy groups were significantly lower than those before operation, and the complication probability of the UCP group was less than that of the trabeculectomy group.CONCLUSION: With fewer complications and high safety, UCP combined with anti-VEGF injection can effectively control intraocular pressure and pain in NVG patients.
ABSTRACT
· AIM: To search an easy and simple way for intraocular implantation after the eye evisceration.· METHODS: Fifteen healthy New Zealand rabbits were divided into 5 groups according to the sacrifice time, and each group included 3 rabbits; the left eye received the injection of polymethyl methacrylate (PMMA) bone cement (2g per mL), while the right eye served as control. Under general anesthetia, a 3mm incision was made on the sclera,and the eye contents and pigment tissues were extruded out with fingers. Then, PMMA bone cement (2g per ml) was injected through the scleral incision. Both the operated eye and control eye of the rabbits were enucleated and weighed,The reaction of the operated eye (macroscopically and histopathologically) was noted at frequent interval. The obtained data were then analyzed with ANOVA (SPSS11.5).· RESULTS: There was swelling of eyelids and conjunctiva at the early time after the injection, but no significant difference between the weight of the left and right eyes was noted,Histopathologic examination showed scleral and other tissues necrosis at early period, and then the tissues reaction turned into a great deal of cell proliferation and finally into extensive fibro-connective tissues. Three months after the operation,neovascularization was observed in the cornea of the operated eyes. Histopathologic examination showed formation of fibro-membrane around the intraocular implant,and disappearance of the inflammation.· CONCLUSION: The method of injecting PMMA bone cement (2g per ml) to form an intraocular implant is quite simple and economical; this method is also easy to use clinically.
ABSTRACT
<p><b>OBJECTIVE</b>To analyze the changing of age patterns among rubella patients after implementing rubella vaccine immunization to children in Shandong province since 1995.</p><p><b>METHODS</b>Epidemiologic data on rubella through surveillance system for suspected measles from 1999 to 2004 and data on rubella vaccination were used and analyzed.</p><p><b>RESULTS</b>The annual average incidence rate of rubella from 1999 to 2004 had been 0.59 per 100 thousands population while 81.17% of cases were concentrated during the outbreaks. 77.77% of the cases were school children between 7-15 years old and 7.93% of the cases were under 7 years old. The age-median of cases were 10.37, 11.66, 11.41, 12.81, 14.28 and 13.96 years old from 1999 to 2004, respectively. The estimated coverage of rubella vaccine for pre-school children was about 60% but only 20% were for school children.</p><p><b>CONCLUSION</b>The peak age of cases moved from youth towards adolescence which indicated that women with child-bearing age might have been under risk of developing the congenital rubella syndrome (CRS). It is necessary to carry out screening test of rubella antibody and vaccination to women with child-bearing age and the immunization strategy should be established to guide the control of rubella and CRS.</p>

Objective To investigate the effect of neonatal mechanical ventilation on lung function and recurrent respiratory diseases of patients.Methods Lung function and recurrent respiratory diseases were studied in 16 children who had been ventilated at birth and were followed up in 8 years later.Results Fifty percentage of them had recurrent respiratory diseases and 75 % of had lung function abnormalities, in which residual volume/ total lung capacity (RV/ TLC) was 56.25 %,43.7 % (Vmax 25),specific airway resistance (sRaw) and specific airway conductance (sGaw) 50 % respectively. The forced expiratory flow during 25 %-75 % of forced vital capacity (FEF 25 %-75 %) and maximal expiratory flow rate at 50 % FVC (Vmax50) in the high peak respiratory pressure (PIP) group were lower than those in low PIP group (P
