ABSTRACT
Objective:To investigate the correlation of the expressions of programmed death ligand 1 (PD-L1) and interleukin-10 (IL-10) with the prognosis in uterine cervical cancer tissues.Methods:A total of 82 patients with uterine cervical cancer hospitalized at Nantong Maternal and Child Health Hospital from January 2015 to December 2019 were retrospectively analyzed, and the clinicopathological data of all patients were collected and sorted out. Immunohistochemical method was used to detect the positive expression of PD-L1 protein in cancer tissues, and Western blot was used to detect the expression level of IL-10 protein in cancer tissues. The survival of all patients for 24-month follow-up was recorded and 82 patients were divided into the survival group and the death group. The clinicopathological characteristics and the expressions of PD-L1 and IL-10 in both groups were compared. Multivariate Cox proportional risk model was used to analyze the factors affecting the survival of patients with uterine cervical cancer. The value of PD-L1 and IL-10 expressions predicting the survival in uterine cervical cancer was evaluated by using receiver operating characteristic (ROC) curve. The best cut-off value of IL-10 relative expression in cancer tissues obtained from ROC curve analysis predicting 24-month survival of patients was used to group; ≥ the best cut-off value was treated as IL-10 high expression group, and < the best cut-off value was treated as IL-10 low expression group. Kaplan-Meier method was used to compare the survival of PD-L1 positive and negative groups, IL-10 high and low expression groups.Results:There was no loss of follow-up in 82 patients during 24-month follow-up, of which 11 cases (13.4%) died and 71 cases (86.6%) survived. The proportion of patients with Federation International of Gynecology and Obstetrics (FIGO) staging Ⅲ-Ⅳ, poor differentiation, tumor long diameter > 4 cm and lymph node metastasis in the death group was higher than that of those in the survival group (all P < 0.05). PD-L1 was positive in 9 of 11 patients in the death group and 11 of 71 patients in the survival group ( P < 0.001). The relative expression level of IL-10 protein in the death group was higher than that in the survival group (1.18±0.32 vs. 0.89±0.21, P < 0.001). Multivariate Cox regression analysis showed that FIGO staging, tissue differentiation degree, tumor long diameter, whether lymph node had metastasis or not, whether PD-L1 was positive and the relative expression level of IL-10 protein were independent factors affecting patients' 24-month survival (all P < 0.05). ROC curve analysis showed that the area under the curve (AUC) of PD-L1 and IL-10 single and the combination of both predicting 24-month survival in cancer tissues was 0.748 (95% CI 0.664-0.894), 0.710 (95% CI 0.655-0.884) and 0.839 (95% CI 0.742-0.951), respectively. There were 20 cases in PD-L1-positive group and 62 cases in PD-L1-negative group. The best cut-off value of relative expression level of IL-10 protein was 7.12. There were 19 cases in IL-10 high expression group and 63 cases in IL-10 low expression group. The overall survival of patients in PD-L1-positive group was worse than that in PD-L1-negative group (24-month overall survival rate: 55.0% vs. 96.8%, P = 0.001). The overall survival of patients in IL-10 high expression group was worse than that in IL-10 low expression group (24-month overall survival rate: 57.9% vs. 95.2%, P = 0.001). Conclusions:The prognosis of patients with positive PD-L1 and IL-10 high expressions in uterine cervical cancer tissues is poor. The combined detection of PD-L1 and IL-10 has a high predictive effect on the prognosis.
ABSTRACT
Objective:To explore the surgical method and therapeutic effect of repairing thumb pulp defect with pedicled transposition of radial proper palmar digital artery flap of middle finger.Methods:Since June, 2006 to May, 2020, 17 cases(17 fingers) with thumb pulp defect were repaired by pedicled transposition of radial proper palmar digital artery flap of middle finger. The sizes of flap ranged from 1.5 cm × 1.5 cm to 4.2 cm × 2.0 cm. The antegrade pedicled flap of radial proper palmar digital artery of middle finger was used in 2 cases and the retrograde pedicled flap of middle finger was used in 15 cases. After the flap was resected, the donor sites were covered with a medium thickness skin graft transferred from the wrist or elbow. The skin graft did not need to be packed. The dorsal branch of the digital nerve was included in the flap and it was anastomosed with the proper nerve of the injured thumb stump. After 16-22 days of the operation, the pedicles were cut off. The patients were instructed to perform digit function exercise after the pedicle was cut off. After the operation, the patients were included in regularly follow-up through outpatient visit, telephone or WeChat interview. The appearance and sensation of the thumb and finger pulps and the function recovery of the thumb and finger joints were observed through the followed-ups.Results:All 17 flaps and donor site skin grafts survived over 3 to 32 months of follow-up. The flaps achieved good texture and natural appearance. The TPD recovered to 5~11 mm. According to the Michigan Hand Function Questionnaire, all the 17 patients were very satisfied with the overall appearance and function of the hands. According to TAM, the 17 cases were all in excellent.Conclusion:Repairing thumb pulp defect with radial proper palmar digital artery pedicled flap of middle finger, the flap resection is simple, and the donor site is hidden. The appearance and texture of flap is good. It is a safe, effective and good method.

ABSTRACT
Purpose: To observe the long-term and recent clinical effect of needle-warming method plus functional training in the treatment of osteoarthritis of the knee joint. Methods:After 106 cases of the patients were divided into the needle-warming group and comprehensive group by the order of their first visit, the needle-warming group was treated by the needle-wanning method and the comprehensive group was treated by the needle-warming method plus functional training. After ten treatments, the clinical data in the two groups were evaluated upon Lequesne scale before and after the treatments. Three months later, follow-up survey was given to process the statistic management of the reoccurrence rate of the symptoms.Results: In the two groups after the treatment, the symptoms of the knee joint and daily life ability were obviously improved than the respective conditions before the treatment, and the integral decreased (P＜0.05), with no significant difference (P＞0.05) between the two groups. In the follow-up survey, there was a difference (P＜0.05) between the two groups in the positive rate of the recurrent symptoms. Conclusion: Certain therapeutic effect exists in the treatment of osteoarthritis of the knee joint by the needle-warming method. If functional training is combined,the therapeutic effect would be more stable, without easy reoccurrence.
