0.05).Statistical analysis showed that there was a correlation between the expression of CTGF and TGF-?RⅡ,FN,and collagen Ⅰ and Ⅲ protein,respectively. Conclusions The expression of CTGF and TGF-?RⅡ protein is up-regulated in PRM of PVR,which suggests that the activation of TGF-?RⅡ is involved in the production of CTGF,and CTGF is closely related to the production of ECM and play an important role in the pathogenesis of PVR.

Objective To study the correlation between thyroid autoantibodies anti‐thyroid peroxidase antibody (TPOAb) with recurrent miscarriage to seek the objective data indicator for clinical diagnosis of recurrent miscarriage .Methods A total of 1 016 pregnant women of physical examination and normal thyroid function in the obstetric and gynecologic clinic of our hospital from March 2012 to May 2014 were selected as the research subjects .Among them ,90 cases of abortion were screened out and di‐vided into the primary abortion group(60 cases) and the recurrent abortion group(30 cases) .90 healthy childbearing age women of physical examination were selected as the control group .The positive TPOAb cases were performed statistics and compared among various groups ,the ratio was calculated;the TPOAb level was recorded in each group .At the same time the correlation between TPOAb with recurrent abortion was analyzed .Results The TPOAb positive rate in the recurrent abortion group was 46 .67% , which was significantly higher than 25 .00% in the primary abortion group and 4 .44% in the control group;at the same time the TPOAb positive rate of primary abortion group was also significantly higher than that of the control group ,the difference had sta‐tistical significance (P<0 .05) .The TPOAb concentration level in the recurrent abortion group was significantly higher than that in the primary abortion group and the control group;the TPOAb concentration level in the primary abortion group was also signifi‐cantly higher than that in the control group ,the differences were statistically significant (P< 0 .05) .In the follow‐up of adverse pregnancy occurrence with recurrent abortion as the adverse pregnancy event ,and according to the method of Spearman correlation analysis ,with the increase of TPOAb level ,the occurrence rate of recurrent miscarriage was higher ,which showed the positive cor‐relation(r=0 .764 ,P=0 .000) .Conclusion Monitoring the patient′s TPOAb level can better show the symptoms of recurrent abor‐tion .

Objective:To investigate the fundus fluorescein angiography (FFA) characteristics of spontaneous regression in retinopathy of prematurity (ROP) and the range of retinal vascularization.Methods:A clinical retrospective study. A total of 82 eyes of 41 infants with ROP, who underwent FFA from January 2019 to December 2021 in Department of Ophthalmology of Xijing Hospital after completion of ROP regression, were included. There were 25 males (50 eyes) and 16 females (32 eyes). ROP was diagnosed in Zone Ⅱ in 44 eyes, with 38 eyes in stage 2 and 6 eyes in stage 3, and in zone Ⅲ in 38 eyes of stage 2. All patients underwent FFA examination under general anesthesia, at postmenstrual age of 70.70±12.25 weeks, after the natural regression of ROP was completed. Focus on the retinal vascular development, as well as choroid circulation and macular abnormalities, and compare and observe the differences between zone Ⅱ and Ⅲ after spontaneous regression. The extent of retinal vascularization was determined by the ratio between the distance of the center of the disc to the border of the vascularized zone (DB) and the center of the disc to the fovea distance (DF). The width of avascular area, recorded as the distance from the ora serrata to the vascular termination, was counted by disc diameters (DD). The measurement data between zone Ⅱ and zone Ⅲ ROP were compared by the independent sample t-test, and the count data were compared by χ2 test or Fisher exact probability test. Results:The linear choroidal pattern was present in 9 eyes (21.95%, 9/41), and the tortuous arteries in the posterior retina were detected in 32 eyes (39.02%, 32/82). It was noted that increased branching of vessels presented in 45 eyes (54.88%, 45/82), straight shape of vessels shown in 27 eyes (32.93%, 27/82), circumferential vessels arisen in 45 eyes (54.88%, 45/82), arteriovenous shunt appeared in 18 eyes (21.95%, 18/82), and capillary bed lost in 46 eyes (56.10%, 46/82) in areas from initial ridge to vascular termini. Punctate or linear dye leakage was observed in 23 eyes (28.05%, 23/82) during the late phase of FFA. Macular abnormalities, such as the absence of foveal avascular zone and hypoperfusion, were observed in 28 eyes (34.15%, 28/82), of which the macular ectopia presented in 1 eye. The mean DB/DF ratio of all the 82 eyes on the temporal side was 4.63±0.29 and 3.77±0.23 in the nasal. The mean avascular area on the temporal retina was 1.74±1.00 DD. Compared with ROP in zone Ⅲ, increased branching of vessels and dye leakage were more common ( χ2=9.303, 10.774; P=0.002, 0.001), the extent of temporal retinal vascularization was smaller ( t=-2.285, P=0.026), and the avascular area of the retina was more significant ( t=5.491, P<0.001) in zone Ⅱ ROP. Conclusions:Even after completion of spontaneous regression in ROP, incomplete retinal vascularization and vascular abnormalities may exist permanently in FFA, including those such as the tortuous arteries in the posterior retina, increased branching and straight shape of vessels, circumferential vessels, capillary bed lost and macular abnormality. Further appropriate follow-up is needed for long-term safety.

Objective: To evaluate the clinical effectiveness of combining electrical stimulation with manual massage in treating women′s myofascial pelvic pain (MPPS). Methods: A total of 93 MPPS patients were recruited and randomly divided into an infrared irradiation group (n=30), an electrical stimulation group (n=31) and a combination group (n=32). Those in the infrared group and the electrical stimulation group were given 30 minutes of infrared irradiation or electrical stimulation daily for 10 days, while the combined group was given a manual massage with electrical stimulation. The response to treatment was evaluated using a visual analogue scale (VAS) to rate discomfort, plus a physical examination, and surface electromyography results using Glazer′s protocol. The treatments′ efficacy and the recurrence of pain were evaluated 1 month after the treatment. Results: The average VAS ratings, resting potentials and their variability of the three groups all improved significantly after the treatment. The average VAS scores of the combined and electrical stimulation groups after the treatment were significantly lower than that of the infrared group. Moreover, the total effective rates of the combined group (96.87%) and the electrical stimulation group (80.65%) were significantly higher than that of the infrared group (56.67%), and the resting potential and variability of the former two groups were also significantly better. All of the above measurements among the combined group after the treatment were significantly better, on average, than in the electrical stimulation group. A month later the recurrence rate in the combined group (6.25%) was significantly lower than in the electrical stimulation group (25.81%) and the infrared group (56.67%). Conclusion Electrical stimulation combined with manual massage is effective in relieving myofascial pelvic pain.
