ABSTRACT
Objective:To investigate the characteristics of congenital hypothyroidism (CH) in premature infants and analyze the predictors of transient congenital hypothyroidism(TCH) and permanent CH (PCH).Methods:A retrospective study was conducted on the preterm infants with CH born in Beijing from January 2008 to June 2018. They were screened, diagnosed and treated by the Beijing Neonatal Disease Screening Center. They were assigned into TCH and PCH groups according to the clinical prognosis. Univariate analysis and Logistic regression analyses were used to determine the predictors of PCH, and the receiver operating characteristic curve (ROC) was drawn to determine the best cut-off point.Results:A total of 2 216 892 newborns were screened, 15 382 were initially screened positive, the median time of screening was 4(4,10) d after birth, and the median time of postnatal reexamination was 30(22,42) d after birth, 14 576 newborns were reexamined, the reexamination rate was 94.8%. A total of 92 preterm infants were diagnosed with CH, of which 60 were TCH, accounting for 65.2%; 28 were PCH, accounting for 30.4%; and 4 were lost to follow-up, accounting for 4.3%. Univariate analysis showed that in the PCH group, the abnormal rate of thyroid B-ultrasound, levothyroxine (LT4) dose at 1-year old, thyrotropin (TSH) level at 2 years old, LT4 dose at 2 years old, LT4 dose and free thyroxine (FT4) level at 3 years old were higher than those in the TCH group. Logistic regression analysis revealed that abnormal B-ultrasound ( OR=12.184,95% CI 2.270~65.403), and elevated TSH level at 2 years old ( OR=2.033,95% CI 1.280~3.228),increased LT4 dose at 3 year old ( OR=21.435,95% CI 3.439~133.584) are the risk factors for PCH. The maximum area under ROC curve was 0.798 at 3 years old (95% CI 0.680~0.916), the best cut-off point was 1.3 μg/(kg·d) for the 3-year-old drug dose; followed by 2-year-old TSH level, which was 0.683 (95% CI 0.548~0.817), the best cut-off point was 4.51 μIU/ml. Conclusions:TCH accounted for a large proportion of preterm infants with CH. During the follow-up, the increased LT4 dose at 3 years old and the elevated TSH level at 2 years old were the early predictors of PCH.
ABSTRACT
Objective:To analyze the characteristics of thyroid diameter and volume of children aged 8 - 10 years in Gansu Province, and to provide a basis for standardizing B-ultrasound examination of children's thyroid volume and establishing a normal reference value of children's thyroid volume.Methods:The data of thyroid volume by B-ultrasound and urinary iodine determination of children aged 8 - 10 years in Gansu Province were from Institute of Endemic Disease, Gansu Center for Disease Control and Prevention. Based on the measured data of thyroid B-ultrasound of 8 - 10 years children in Gansu Province, the characteristics and relationship between thyroid diameter and volume were analyzed by nonparametric test.Results:The medians of urinary iodine of 8, 9, 10 years children ( n = 500, 503, 496) were 166.62, 167.16 and 178.78 μg/L, respectively. The length, width, thickness and volume of the left and right lobes of the thyroid in children were skewed distribution. There was a positive correlation between the left and right diameters (length, width and thickness) and between left and right thyroid volumes ( r = 0.76, 0.85, 0.72, 0.88, P < 0.001). There was no significant difference in the six diameter lines and volume values of thyroid between genders ( P > 0.05), but there was significant difference between ages ( P < 0.001). The means thyroid volume of 8, 9 and 10 years children were 2.6, 2.9 and 3.2 ml, respectively, the medians were 2.5, 2.7 and 3.0 ml, respectively, and the 97th percentile ( P97) were 4.4, 4.9 and 6.5 ml, respectively. The thyroid volume of 10 years group was higher than the current national standard (6.0 ml). The median ranges of thyroid volume of children aged 8, 9 and 10 years at the county level were from 1.8 ml to 4.1 ml, from 1.8 ml to 4.3 ml and from 1.9 ml to 4.4 ml, respectively. There was significant difference in thyroid volume of children at the county level in all age groups ( P < 0.05). Conclusions:Compared with the national standard, the P97 value of thyroid volume of children aged 8 - 10 years in Gansu Province is slightly different. The reference value of thyroid volume should be formulated according to age, and a unified reference value can be used for different genders at the same age.

ABSTRACT
Objective To investigate the effectiveness of ultrasound in evaluating the degree of xerostomia in the patients with nasopharyngeal carcinoma ( NPC) receiving intensity?modulated radiotherapy (IMRT). Methods A total of 30 NPC patients who were admitted to our hospital from May 2013 to December 2014 were enrolled in this study. The degree of xerostomia in these NPC patients was scored according to the Radiation Therapy Oncology Group scoring criteria. Color Doppler ultrasound was used to measure the peak systolic blood flow velocity of the parotid gland and submandibular gland and the changes in vascular diameter of the parotid gland in the NPC patients before, during, and after IMRT. The correlation between each parameter and the degree of xerostomia was determined by analysis of variance. Results In the 28 NPC patients included in the statistical analysis, the degree of xerostomia during IMRT was significantly higher than that before IMRT ( P=0024 ) , and the degree of xerostomia at 3 months after IMRT was significantly lower than that during IMRT ( P=0035) . The peak systolic blood flow velocity of the parotid gland and submandibular gland and the proportion of patients with decreases in vascular diameter of the parotid gland during IMRT were significantly higher than those before IMRT ( P=0001 and 0003;P=0001);the above parameters at 3 months after IMRT were significantly lower than those during IMRT ( P=0008 and 0012;P=0001) . During IMRT and after IMRT, the degree of xerostomia was significantly correlated with the peak systolic blood flow velocity of the parotid gland ( r=0563, P=0026;r=0409, P=0031) . Conclusions Ultrasound can be used as a noninvasive detection for the hemodynamic changes in the parotid gland, and it has a certain clinical reference value for evaluating the degree of xerostomia in NPC patients during and after IMRT.

ABSTRACT
PURPOSE: CO₂ leakage along the trocar (chimney effect) has been proposed to be an important factor underlying port-site metastasis after laparoscopic surgery. This study aimed to test this hypothesis by comparing the incidence of port-site metastasis between B-ultrasound-guided and laparoscopically-assisted hyperthermic intraperitoneal perfusion chemotherapy (HIPPC). MATERIALS AND METHODS: Sixty-two patients with malignant ascites induced by gastrointestinal or ovarian cancer were divided into two groups to receive either B-ultrasound-guided or laparoscopically-assisted HIPPC. Clinical efficacy was assessed from the objective remission rate (ORR), the Karnofsky Performance Status (KPS) score, and overall survival. The incidence of port-site metastasis was compared between the two groups. RESULTS: Patients in the B-ultrasound (n=32) and laparoscopy (n=30) groups were comparable in terms of age, sex, primary disease type, volume of ascites, and free cancer cell (FCC)-positive ascites. After HIPPC, there were no significant differences between the B-ultrasound and laparoscopy groups in the KPS score change, ORR, and median survival time. The incidence of port-site metastasis after HIPPC was not significantly different between the B-ultrasound (3 of 32, 9.36%) and laparoscopy (3 of 30, 10%) groups, but significantly different among pancreatic, gastric, ovarian, and colorectal cancer (33.33, 15.79, 10.00, and 0.00%, p<0.001). CONCLUSION: The chimney effect may not be the key reason for port-site metastasis after laparoscopy. Other factors may play a role, including the local microenvironment at the trocar site and the delivery of viable FCCs (from the tumor or malignant ascites) to the trauma site during laparoscopic surgery.

Objective To evaluate the clinical significance of using B-ultrasound combined with color Doppler ultrasonography guidance in percutaneous nephrolithotomy ( PCNL) to decease the incidence of hemorrhagic complication.Methods A total of 323 patients with renal or urethral stones who had undergone PCNL were retrospectively categorized into 2 groups.Group 1 (147 patients) underwent PCNL with single B-ultrasound guidance while group 2 (176 patients) underwent PCNL with combined B-ultrasound and color Doppler ultrasound guidance. The clinical characteristics and complications, especially hemorrhagic complications in the two groups were recorded and compared.Results There were no statistical significances in age [ ( 53.2 ±12.9 ) years vs.( 54.7 ±9.1 ) years ] , hight [ ( 165.1 ±8.5 ) cm vs.( 164.6 ± 6.9) cm], weight[ (66.1 ±19.2) kg vs.(64.9 ±16.3) kg], stone burden [(680.5 ±56.4) mm2 vs. (654.0 ±76.9) mm2], operative time[(117.6 ±55.1) min vs.(121.4 ±54.3) min], stone-free rate (90.7%vs.91.3%), or postoperative hospital stay [(4.9 ±2.2)d vs.( 4.7 ±1.7 )d] between the two groups.In the B-ultrasound combined color Doppler ultrasound guidance group, the rate of blood transfusion (1.1%vs.3.4%) and super-selective embolization (0 vs.3.4%) was significantly lower than that of the single B-ultrasound guidance group.Besides, the incidents of renal arteriovenous fistula (0 vs.2.0%), pseudoaneurysm (0 vs.2.0%), and perirenal hematoma (0 vs.1.4%) were significantly lower in the B-ultrasound combined color Doppler ultrasound guidance group than that of the single B-ultrasound guidance group.Conclusion Using B-ultrasound combined color Doppler ultrasound guidance during PCNL resulted in the real-time detection and avoidance of the renal blood vessels during puncture and decreased the incidence of hemorrhagic complications.
ABSTRACT
Background and purpose:Since the number and tumor size of localized liver metastases can be controlled, local minimally invasive treatment can improve the survival of patients. Hence, microwave ablation has become an important treatment method for liver metastases. This study was to investigate the value of percutaneous microwave ablation in the treatment of tumor metastases. Methods: From Sep. 2011 to Oct. 2014, 26 advanced nasopharyngeal carcinoma patients with post-chemotherapy consolidation, liver metastases were collected. All the patients with the number of tumor lesions less than 3, diameter less than 5 cm, no other distant metastases was excluded. The ultrasound-guided percutaneous microwave ablation was used for 26 patients. Finally, 43 ablations were completed followed by liver function test, enhanced CT and MRI diagnosis 1 month later. mRECIST criteria was used to evaluate the effcacy of cancer treatment. Progression-free survival (PFS) and overall survival (OS) were calculated. Results:Twenty-six cases of a total of 53 lesions, including complete ablation (CA) 20 patients (20/26, 77.0%), partial ablation (PA) 3 patients (3/26,11.5%). The overall effciency was 88.5%(CA+PA) with no serious complications. 6 months, 1-, 2-year survival rates of 26 patients were 96.1%, 65.3%and 23.0%. PFS was 11.4 months. The median survival time (MST) was 11.9 months, while OS was 23.7 months. Conclusion:Percutaneous microwave ablation for limited liver metastases of nasopharyngeal carcinoma is a minimally invasive, safe and effective treatment method.
ABSTRACT
Background and purpose:When the patients with nasopharyngeal carcinoma (NPC) receive radiotherapy, their thyroids are inevitably involved. As a result, thyroid damage occurs. This study aimed to explore the effects of intensity modulated radiation therapy (IMRT) on dynamics of thyroid blood flow in patients with NPC.Methods:A total number of 68 patients with NPC were enrolled in the study who received primary treatment of radical radiation and chemotherapy from Jul. 2012 to Oct. 2013. And the TMN stage was fromⅡ toⅣc according to UICC 2010. The treatment method consisted of 2 cycles of TPF induction treatment, concurrent radiation therapy (IMRT) with 2 cycles of DDP and 2 cycles of adjuvant therapy sequentially. Before radiotherapy, at the end of radiotherapy, 3 and 6 months after radiotherapy, serum free triiodothyronine (FT3), free thyroxin (FT4) and thyroid-stimulating hormone (TSH) concentrations of all cases were detected by electrochemiluminescence. The highest systolic velocity, mean velocity, minimum diastolic velocity, resistance index, and the value of all thyroid diameter lines were measured by type-B ultrasound.Results:All the patients were followed up for 6 months. Hypothyroidism: the incidence of immediate clinical hypothyroidism after radiotherapy was 5.9%; 3 months later, the incidence was 13.2%; and 6 months later, the incidence was 26.5%. The difference in volume change between before radiotherapy and at the end of radiotherapy had no statistical signiifcance (P>0.05). The difference in volume change between 3 and 6 months after radiotherapy had statistical signiifcance (P0.05).Conclusion:The incidence of hypothyroidism may increase with time after radiotherapy. The volume may decrease with the increased dose of radiotherapy and the follow-up time. The patients with NPC after radiotherapy should be tested for thyroid lesions routinely. The thyroid dose-volume parameter V40 may be a predictor for acute radioactive thyroid lesions. The study did not reveal temporarily that hypothyroidism was associated with thyroid ultrasound blood lfow velocity.

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.
