Objective:To investigate the iodine nutritional status of pregnant women in Hangzhou City and analyze its influencing factors, in order to provide a basis for guiding pregnant women in Hangzhou City to supplement iodine scientifically.Methods:A stratified random sampling method was used to conduct a questionnaire survey on 1 400 pregnant women in Hangzhou City from March to October 2018. Random urine samples and household salt samples from pregnant women were collected, and the levels of urine iodine and salt iodine were measured using arsenic cerium catalytic spectrophotometry and direct titration, respectively. The iodine nutritional status of pregnant women with different basic characteristics and dietary levels were analyzed and compared (Kruskal-Wallis test), and the main influencing factors affecting the urinary iodine concentration level of pregnant women were identified (the ordinal multiple classification logistic regression analysis).Results:The median urinary iodine of pregnant women was 135.00 μg/L, and the qualified iodized salt consumption rate of pregnant women was 83.36% (1 167/1 400). In terms of basic characteristics, there were statistically significant differences in the distribution level of urine iodine among pregnant women with different pregnancy frequency, delivery frequency, and natural abortion frequency ( P < 0.05). In terms of diet, the frequency of consuming milk, yogurt, meat, and whether pregnant women consumed cabbage and cauliflower showed statistically significant differences in urinary iodine distribution levels ( P < 0.05). Ordinal multiple classification logistic regression analysis showed that the urine iodine levels of pregnant women who were pregnant twice were higher than those who were pregnant ≥3 times ( OR = 1.64, P = 0.003). Pregnant women who never or occasionally consumed yogurt had lower urine iodine levels than or equal to those who consumed 2 bottles of yogurt per day ( OR = 0.53, P = 0.044). Pregnant women who never or occasionally consumed meat and those who consumed meat once a week had higher urinary iodine levels than that who consumed meat ≥2 times per week ( OR = 1.40, 1.47, P < 0.05). Conclusions:The overall iodine nutrition of pregnant women in Hangzhou City is at an deficiency level. Pregnancy experience and dietary level are influencing factors on iodine nutrition of pregnant women. It is necessary to carry out in-depth health education for pregnant women, improve the dietary structure during pregnancy, and improve the abnormal iodine nutrition of pregnant women.

Glioma remains the most common malignant tumor in the brain and is also the most difficult to treat. Immunotherapy achieving long-lasting tumor remission in multiple cancer types has received considerable attention due to its potential to improve the treatment outcomes of patients with glioma. However, clinical trials have not yet demonstrated major improvements in prognoses, which might be attributable to the extrinsic components and intrinsic mechanisms involved in the tumor microenvironment and immune system. It is particularly noteworthy that there is emerging evidence that current routine treatment modalities and the physical and psychological characteristics of patients have different impacts on the efficacy of glioma immunotherapy. This article addresses how these factors interact with the host immune system and tumor microenvironment, and highlights their potential roles in glioma immunotherapy, with the ultimate goal of developing better immunotherapybased personalized medicine strategies.

Objective To evaluate the predictive values of serum neutrophil gelatinase-associated lipocalin (NGAL), urine NGAL, serum cystatin C (Cys-C) and serum creatinine (Scr) for early delayed graft function (DGF) in kidney transplant recipients. Methods Clinical data, blood and urine samples of 159 kidney transplant recipients were collected. All recipients were divided into the DGF group (n=42) and immediate graft function (IGF) group (n=117) according to the incidence of DGF. Clinical data of all recipients were analyzed. The changes of serum NGAL, urine NGAL, Cys-C and Scr levels were statistically compared between two groups. The predictive values of different markers for early DGF were assessed. Results Among 159 kidney transplant recipients, DGF occurred in 42 cases with an incidence rate of 26.4%. There were statistically significant differences in donor age, cold ischemia time of donor kidney and complement-dependent cytoxicity (CDC) between the two groups(all P < 0.05). Within postoperative 2 weeks, the serum NGAL levels in the DGF group were higher than those in the IGF group (all P < 0.05). The Cys-C, Scr and urine NGAL levels in the DGF group were higher compared with those in the IGF group within 3 weeks after kidney transplantation(all P < 0.001). Serum NGAL, urine NGAL, Cys-C and Scr levels had certain predictive values for early DGF in kidney transplant recipients. Cys-C yielded the highest predictive value with a cut-off value of 4.73 mg/L, sensitivity of 0.833, specificity of 0.812 and area under the curve (AUC) of 0.895. Conclusions Cys-C has higher predictive value for early DGF in kidney transplant recipients compared with serum NGAL, urine NGAL and Scr.

Objective: To compare diagnostic performance of traditional vertical section technique, horizontal section technique and modified Ho-Vert technique for classical lichen planopilaris. Methods: Clinical data were collected from patients with classical lichen planopilaris in Department of Dermatology, The Affiliated Wuxi People′s Hospital of Nanjing Medical University from January 1st 2015 to January 1st 2019. With the help of dermoscopy, 2 scalp specimens were obtained from each patient and sliced horizontally and vertically respectively by using modified Ho-Vert technique. The horizontal and vertical sections were read separately or simultaneously, and histopathological changes were observed. Results: Totally, 21 patients with classical lichen planopilaris were enrolled into this study, including 15 males and 6 females. Their age was 50.0 ± 13.6 years, and the average course of disease was 18 months. The patients mainly presented with multifocal or confluent patchy hair loss, and scalp atrophy, perifollicular hyperkeratosis, loss of follicular ostia, fibrous white dots and orbit sign were observed. On the horizontal sections, lichenoid lymphocytic infiltration around the infundibulum and isthmus of hair follicles and follicular micro-scars could be observed in all patients, and the dermo-epidermal interface could be seen in 7 patients. On the vertical sections, lichenoid lymphocytic infiltration around the infundibulum and isthmus of hair follicles only could be observed in 9 patients, follicular micro-scars could be seen in 4, and the dermo-epidermal interface could be observed in all patients. Moreover, the detection rates of interfollicular interface dermatitis, follicular keratotic plugs, lymphocytic infiltration around sebaceous glands, atrophy or disappearance of sebaceous glands and inflammatory infiltration around hair follicle bulbs were significantly different between the horizontal and vertical sections. In combination with clinical manifestations, 7 patients could be exactly diagnosed with lichen planopilaris according to findings from horizontal sections, and 9 could be diagnosed exactly according to findings from vertical sections, while 21 could be diagnosed exactly according to histopathological findings from both horizontal and vertical sections. Conclusion With the help of dermoscopy, modified Ho-Vert technique can improve the efficacy of pathological diagnosis of classical lichen planopilaris, by multidimensionally showing histopathological changes.

Objective: To analyze dermoscopic features of blue nevi. Methods: Clinical and dermoscopic data were collected from patients with confirmed blue nevi in the Department of Dermatology and Venereology, Wuxi People′s Hospital from January 2008 to May 2018, and analyzed retrospectively. Chi-square test was used to analyze differences between groups. Results: Totally, 65 patients with 66 skin lesions were enrolled into this study. A total of 23 skin lesions were subjected to dermoscopy, which showed homogeneous pattern in 20 (87.0%) lesions, pseudo-pigment network pattern in 2 (8.7%) lesions, and cerebriform pattern in 1 (4.3%) lesion, and the homogeneous pattern was more common than the other patterns (χ² = 8.79, P < 0.05) . Under the dermoscope, 10 lesions were monochromatic (43.5%) , 11 were dichromatic (47.8%) , and 2 were multichromatic (8.7%) . Scar-like hypopigmentation was observed in 4 lesions (17.4%) , and vascular structures were observed in 5 (21.7%) , including punctate vessels in 4 (17.4%) and linear irregular vessels in 1 (4.3%) . Papillary hyperplasia was observed in 2 lesions (8.7%) . Additionally, pigmentation around lesions, white streaks, dots/globules, blotches, comedo-like openings were observed in 1 lesion (4.3%) each. Conclusions Blue homogeneous pattern is the most common dermoscopic feature of blue nevi. Pseudo-pigment network pattern, cerebriform pattern, scar-like hypopigmentation, multiple vascular patterns, papillary hyperplasia, white streaks, dots/globules, blotches, comedo-like openings can also be observed in blue nevus lesions.

Objective To investigate the diagnostic accuracy of magnetic resonance imaging and ultrasound (MRI/US) fusion targeted biopsy (TB) and systematic biopsy (SB) in the patients with prostate specific antigen (PSA) in grey area.Methods The patients who received MRI/US fusion TB and SB in the First Affiliated Hospital of Soochow University between October 2015 and March 2018 were retrospectively reviewed.Eligibility criteria included:tPSA ranged 4 to 10 ng/ml;prebiopsy MRI found at least 1 suspected lesion;no prostate-related treatment history;no prostate biopsy history.A total of 93 patients were invloved.The median age,tPSA and prostate volume were 66 (30-85) years,7.18 (4.11-9.95) ng/ml and 42.01 (14.93-119.15) ml,respectively.Prebiopsy MRI found 136 suspected lesions,with the median PI-RADS of 3 (3-5) and lesion size of 7 (3-20) mm.All patients underwent MRI/US fusion TB followed by SB.The comparison of two protocols in detecting any prostate cancer (PCa) as well as clinically significant prostate cancer (CsPCa) were analyzed.Results Cancer detection rates for PCa in TB [34.40％ (32/93)] was not different with SB [36.55％ (34/93),P =0.759].There was no significant difference in the detection rate of CsPCa between TB and SB [20.43％ (19/93) vs.24.73％ (23/93),P=0.483].A total of 1 374 biopsy cores were sampled,among which 266 were TB cores and additional 1108 were SB cores.The positive rate of TB cores [24.81％ (66/266)] was significantly higher than SB cores [9.84％ (109/1 108),P ＜0.001].Conclusions In the patients with PSA in grey area,MRI/US fusion TB achieved similar cancer detection rate compared with SB using only few biopsy cores.Therefore,TB was appropriate for patients with MRI suspicions.Moreover,combination of TB with SB can achieve the highest cancer detection rate.

Objective To compare the differences in setup error ( SE) assessment and correction between three-dimensional cone-beam computed tomography ( 3DCBCT ) and four-dimensional CBCT ( 4 DCBCT ) in breast irradiation patients during free breathing after breast-conserving surgery . Methods Twenty patients with breast cancer after breast-conserving surgery were recruited for external beam breast irradiation and 4DCBCT and 3DCBCT simulation. The target volumes were delineated. Volumetric modulated arc therapy plans were designed using the MONACO v510 treatment planning system. 3DCBCT and 4DCBCT images were collected alternately five times each before breast irradiation. The CT images were matched, and the interfraction SEs were acquired. After online setup correction, the residual errors were calculated, and the SEs, systematic errors, and random errors were compared. The paired t test was used for comparison between groups. Results The SEs acquired by 4DCBCT were significantly larger than those acquired by 3DCBCT in three directions ( P=0035, 0018, 0040 ) . After online setup correction, the random errors based on 3DCBCT were significantly smaller than those based on 4DCBCT in left-right and anterior-posterior ( AP ) directions ( 0.5± 039 mm vs. 0.7± 030 mm, P=0005;0.9± 109 mm vs. 1.2± 048 mm, P=0000) , and the residual errors based on 3DCBCT were also significantly smaller than those based on 4DCBCT in AP direction (0.2±033 mm vs. 0.6±063 mm, P=0000). The setup margins based on 4DCBCT was significantly larger than those based on 3DCBCT in AP direction both before and after online setup correction (P=0002). Conclusions Compared with 3DCBCT, 4DCBCT has more advantages in monitoring the SEs in three directions. Both 3DCBCT and 4DCBCT have similar efficacy in random error correction. The satisfying position repeatability and minimized target volume margins will be achieved by online setup correction.
