The indication for treating adolescent idiopathic scoliosis (AIS) including development states, bending types, spinal rotation, as well as degree of deformity, but the orthosis occasionally involves in clinic. The third generation internal fixation system, such as CD, TSRH, and Chinese Greatwall system arose more attention with the advancement of spinal cube theory and internal fixation technique. Surgical treatment of scoliosis by fixation of the vertebral pedicle has superior effect in treating deformity at the sagittal/coronal plane or vertebra rotation, which can correct the three dimensional deformities of spinal column and improve patient's back appearance via revolving controlled rod.

Objective To investigate the corrective effect of modified Brisson technique to treat concealed penis in children.Methods From July 2014 to July 2016,selected 12 patients (3-10 years old,mean 7.2 years old) with concealed penis were surgically treated with the modified Brisson technique in the Second Affiliated Hospital of Nanjing Medical University.Their clinical manifestations included the penis buried below the surface of prepubic skin which can be palpated and visualized through pushing the skin around the penis to the pubis and the short foreskin which was not attached to the penile corpus cavernosum.Patients with other conditions such as obesity and penial agenesis that caused buried penis were excluded from the study.The modified Brisson technique consisted of 4 steps.Ventral incision was used to gradually slit the narrow ring of the prepuce and to expose the glans followed by circumfe-rential inner foreskin incision made below the coronary sulcus of penis then the foreskin stripping released the corpus cavernosum.Finally the skin coverage was accomplished by posthioplasty.The operation time,blood loss,complications,postoperative treatments and followed-ups were retrospectively analyzed.Results For all the 12 patients,the operations were successful,lasting 40 to 60 minutes.The bleeding was about 5 to 10 mL and there was no operation-related complications like bleeding and infection of incision.Satisfactory cosmetic outcomes were obtained without retraction and the scars were similar to those of circumcision.All patients had penile lymphedema postoperatively which disappeared within 6 months after operation.Follow-up ranged from 6 months to 1 year,and there were no complications like skin necrosis and contracture or voiding difficulty.Conclusions The modified Brisson technique for concealed penis repair is technically easy and safe.In addition,it provides a good cosmetic appearance,functional outcomes and excellent postoperative satisfaction grades.

Objective To study the application effect of ENCOR vacuum-assisted breast minimally invasive polypectomy system in the diagnosis and treatment of breast tumors. Methods Totally 86 breast cancer patients treated in the General Hospital of Yangmei Group from January 2017 to October 2017 were randomly divided into study group and control group,with 43 cases in each group. The study group was treated with ENCOR vacuum-assisted minimally invasive rotational atherectomy system,while the control group was treated by traditional breast excision. The operative conditions, postoperative complications and postoperative recurrence were observed and compared between the two groups. Results The intraoperative bleeding volume,operation time,scar length and postoperative recovery time in the study group were (5.1 ±1.2)mL,(15.9 ±3.5)min,(0.3 ±0.1)cm,(2.7 ±0.4)d,respectively, which in the control group were (12.7 ±2.3)mL,(26.8 ±4.6)min,(3.2 ±1.1)cm and (5.1 ±0.8)d,respectively, the differences between the two groups were statistically significant ( t=15. 579,14. 297,14. 108,13. 597,all P<0. 05). The total incidence rate of postoperative complications in the study group was 11. 63％,which was significantly lower than 30. 23％ in the control group (χ2 =5. 187,P<0. 05). During the follow-up of 12 months,in the study group,2 patients (4. 65％) had residual tumor,1 patient (2. 33％) developed recurrence; in the control group, 3 patients (6. 98％) had residual tumor,2 patients (4. 65％) developed recurrence. There was no statistically significant difference between the two groups (χ2 =1. 013,P >0. 05). Conclusion ENCOR vacuum - assisted breast minimally invasive revolving system in the treatment of breast tiny tumors has advantages of less trauma and pain,rapid recovery,etc,it is safe and effective.

Objective:To monitor the liver oxygen saturation (rStO 2-liv) and the intestinal oxygen saturation (rStO 2-abd) in very low birth weight infants (VLBW) using near infrared spectroscopy (NIRS) and explore the difference between the two indicators and their clinical significance. Methods:This prospective study included newborns with a birth weight of less than 1 500 g at the Nanjing Women and Children′s Healthcare Hospital, from October 1, 2022 to March 31, 2023.On the 7 th day after birth, Gutcheck NEC scores were evaluated, followed by continuous NIRS measurement for 8 hours.Clinical data and NIRS measurements were collected and comparatively analyzed.The differences between groups were compared by two independent samples t-test and One-Way ANOVA. The diagnostic value of NIRS was analyzed using receiver operating haracteristic curves. Results:A total of 42 VLBW infants were enrolled in this study.There was no statistically significant difference between rStO 2-liv and rStO 2-abd ( P=0.117).According to the Gutcheck NEC score, there were 7 patients in the low-risk group, 29 in the medium-risk group, and 6 in the high-risk group.No statistically significant difference was observed in rStO 2-liv among the different risk groups ( F=2.145, P=0.131).The rStO 2-abd decreased significantly with increasing risk ( F=5.127, P=0.011).The Bland-Altman plot indicated no consistency between rStO 2-liv and rStO 2-abd ( P=0.024).The receiver operator characteristic curve showed that the area under the curve (AUC) for rStO 2-abd diagnosing the high-risk Gutcheck NEC score was 0.800, with a cutoff value of 41.41%, sensitivity of 85.70%, and specificity of 48.60%. Conclusions:Simultaneous measurement of rStO 2-liv and rStO 2-abd using NIRS is safe and feasible in VLBW infants, but the two measures can not be substituted for each other.Low rStO 2-abd (<41.41%) indicates a higher risk of necrotizing enterocolitis in infants.

Objective:To explore the selection of surgical methods for different sites of symptomatic Rathke's cleft cyst (RCC) and the clinical efficacies of these patients.Methods:Forty-seven patients with symptomatic RCC, admitted to our hospital from January 2016 to December 2019, were chosen in our study; 21 patients with intrasellar symptomatic RCC accepted surgery via unilateral nasal approach at the right side, 19 patients with intra-suprasellar symptomatic RCC accepted surgery via bilateral nasal approach, 3 patients with suprasellar symptomatic RCC accepted endonasal transsphenoidal surgery under endoscope, and 4 patients with suprasellar symptomatic RCC accepted craniotomy via pterion approach. The clinical efficacies and complications of patients accepted different surgical methods were compared. All patients were followed up for 3-36 months to observe the recurrence.Results:The postoperative symptoms of the patients were effectively improved, including headache relief ratio of 27/31, vision loss improvement ratio of 5/5, high prolactin relief ratio of 11/13, pituitary function improvement ratio of 9/18. Complications occurred in 6 patients, presenting as diabetes insipidus. Four patients recurred during follow-up.Conclusion:Intrasellar and intra-suprasellar symptomatic RCC accepted surgery via endoscopic transnasal transsphenoidal approach are safe and effective; selection of surgical methods for suprasellar symptomatic RCC should be determined according to the sizes and growth directions of cysts.

Objective:To evaluate the clinical efficacy of microneedle radiofrequency in the treatment of moderate acne vulgaris.Methods:From August 2018 to August 2020, 393 patients (192 males and 201 females, aged 15-38 years) with moderate acne were enrolled in the Department of Dermatology, the First Affiliated Hospital of Shantou University Medical College and Shantou Chaonan Minsheng Hospital, including 201 patients in experimental group and 192 patients in control group. In the experimental group, microneedle radiofrequency therapy was used once every 2 weeks for 3 times in total. The control group adopted the fire needle, once every 2 weeks, a total of 3 times. The efficacy of both groups was evaluated at week 8.Results:A total of 378 patients were actually completed: 196 patients in the experimental group, and 182 patients in the control group. At the eighth week of follow-up, the total effective rate was 81.12% in the experimental group and 70.43% in the control group. The efficacy of the two groups was statistically different (χ 2=4.42, P<0.05). Conclusions:The efficacy of microneedle radiofrequency therapy in the treatment of moderate acne vulgaris is better than that of fire needle, with good tolerance, short recovery period, few adverse reactions and high compliance, which has clinical promotion value.
