RESUMEN
Objective:To observe and analyze the superficial retinal blood flow density and its related influencing factors in the macular area of adolescents with different types of non-pathological high myopia (HM).Methods:A retrospective clinical study. From March to August 2022, 117 eyes of 117 adolescents who were admitted to Liaocheng Aier Eye Hospital due to myopia were included in the study. According to equivalent spherical degree (SE) and corneal curvature, subjects were divided into mild myopia or emmetropia group (control group), HM group, occult HM (OHM) group, and super HM (SHM) group, with 30 eyes, 28 eyes, 35 eyes, and 24 eyes, respectively. All subjects underwent medical optometry, intraocular pressure, optical coherence tomography (OCT), OCT angiography (OCTA), axial length (AL) and corneal curvature measurements. The diopter was SE. OCTA instrument was used to scan the macular region in the range of 6 mm×6 mm, and the software automatically divided it into three concentric circles centered on the fovea of the macular, namely, the central area with a diameter of 1 mm, the inner ring area with a diameter of 1-3 mm, and the outer ring area with a diameter of 3-6 mm. The superficial retinal vascular density (SRVD), vascular perfusion density (SBPD), the area, perimeter (PERIM), avascular index (AI) of foveal avascular area (FAZ) and retinal thickness were measured in the macular region as a whole and in different regions. One-way analysis of variance was used to compare the data among groups, and the least significant difference t-test was used to compare the data among groups. The correlation of AL, corneal curvature and intraocular pressure with SRVD and SBPD in macula was analyzed by Pearson correlation analysis. Results:There were significant differences in SRVD and SBPD in the central, inner and outer regions of macula in control group, HM group, OHM group and SHM group ( P<0.05). There were statistically significant differences in the thickness of the retina above, below and on the temporal side of the central and outer ring regions ( P<0.05). However, no statistically significant difference was in the thickness of the retina on the nasal side ( P>0.05). There was no significant difference in PERIM ( P>0.05). There were significant differences in FAZ area and AI ( P<0.05). Correlation analysis showed that AL was negatively correlated with SRVD and SBPD in macular whole and central, inner and outer ring regions ( P <0.05). Corneal curvature and SE were positively correlated with the SRVD and SBPD of macular whole, central area and outer ring area ( P<0.05). AL was negatively correlated with retinal thickness in the outer ring region ( P<0.05). SE was positively correlated with the thickness of the retina above, below and temporally in the outer ring region ( P<0.05). AL was negatively correlated with FAZ area and AI ( P<0.05). SE was positively correlated with FAZ area and PERIM ( P<0.05). Retinal thickness was positively correlated with SRVD and SBPD ( P<0.05). Conclusions:The SRVD and SBPD of different types of HM in adolescents decreases to different degrees. The thickness of the retina in the central region is thicker, and the retina in the outer ring region is thinner. With the decrease of SRVD, the retinal thickness gradually is thinner.
RESUMEN
Objective To investigate and evaluate the improvement of the quality of life of pulmonary infection in AIDS patients treated by Chinese traditional treatment combined Western medicines treatment.Methods Sixty cases with HIV infection combined with pulmonary infection were selected as our subjects.They were randomly divided into two groups and each group was 30 cases.Patients in western medicine group were given medicine plus placebo,and in Chinese medicine group were given west medicine combined with traditional Chinese medicine.Patients hospitalized for 4 weeks.WHO QOL-HIV plus AIDS-related quality of life scale were used to collect the information about quality of life.Results There were no significant difference between two groups in terms of quality of life,life activity,health status,sleep status,ability to work,leisure opportunities scores at before treatment (P ＞ 0.05).After treatment,the score of quality of life,life activity,health status,sleep status,ability to work,leisure opportunities in patients of Chinese group were (3.78 ± 0.69),(3.55 ± 0.67),(3.55 ± 0.67),(3.18 ± 0.72),(3.66 ± 0.70),(3.03 ± 0.73) respectively,higher than that of western medicine group ((2.90 ± 0.77),(2.75 ± 0.85),(2.75 ± 0.85),(2.85 ± 0.68),(3.35 ± 0.57),(2.95 ± 0.85) respectively,t =-2.791,-2.791,-4.28,-3.08,-4.08,-2.56,P ＜ 0.05).There were no significant differences between the two groups in the terms of the score of satisfaction,sex ability,HIV impaction on the body,the meaning of life,the energy aspects of patients at before treatment (P ＞ 0.05),but after treatment,these scores in Chinese medicine group were higher that in the control group ((3.51 ± 0.67) vs.(2.93 ±0.71),(3.13±0.46) vs.(2.86±0.74),(3.96±0.71) vs.(3.45 ±0.98),(3.66±0.72) vs.(3.23 ± 0.88),(3.23 ± 0.67) vs.(2.90 ± 0.65)),and the differences were statistically significant (t =-4.38,-2.34,-3.75,-2.76,-2.38,P ＜ 0.05).There was no significant difference in the term of the mental effect of HIV within groups at before treatment,but after treatment,the score in Chinese group was lower than the Western group ((3.05 ± 0.90) vs.(3.46 ± 0.87),t =2.31,P ＜ 0.05).Conclusion Chinese medicine combined western medicine can significant improve the quality of life of HIV patients with pulmonary infection.
RESUMEN
Objective To explore the clinical effect of radio frequency catheter ablation( RFCA) guiding by B ultrasound combined with CT on treating primary hepatic carcinoma. Methods Eighty-two patients with primary liver cancer were treated with transcatheter arterial chemoembolization therapy. One week after the operation,41 patients were treated with RFCA guiding by B ultrasound combined with RFA therapy and served as treatment group. Another 41 cases were given RFA treatment guiding by CT as control group. The indices including tumor shrinkage rate,survival rate of 0. 5,1 and 2 years. Results The tumor shrinkage and total effective rates in the treatment and control group were 95. 12%(39 / 41)and 80. 49%(33 / 41),and there was statistically significant difference between the two groups(χ2 = 5. 33,P < 0. 05). After treatment,the survival rates of 0. 5,1and 2 years in treatment group were 100%(41 / 41),82. 9%(34 / 41)and 73. 2%(30 / 41),and that of the control group were 100%(41 / 41),70. 7%(29 / 41)and 51. 2%(21 / 41). There was significant differences between groups in terms of the survival rates of 1and 2 years( χ2 = 3. 96,5. 07,P < 0. 05). Conclusion The curative effect of RFA guiding by B ultrasound combined with CT is significantly superior to that guiding by CT.
