Objective:To investigate the clinical efficacy of honeysuckle extraction liquid combined with nasal irrigation in the treatment of nasosinusitis after radiotherapy of nasopharyngeal carcinoma.Methods:Eighty-two patients with nasosinusitis post-radiotherapy who received treatment between February 2018 and February 2020 in the First Hospital of Jiaxing were included in this study. They were randomly assigned to receive either nasal irrigation with 0.9% sodium chloride injection (control group, n = 41) or atomization treatment with honeysuckle extract liquid plus nasal irrigation with 0.9% sodium chloride injection (observation group, n = 41), once daily for 4 successive weeks. Visual Analogue Scale (VAS) and nasal endoscopic Lund-Kennedy (LK) score, ciliary transport rate, clinical efficacy and adverse reactions were compared between the control and observation groups. Results:After treatment, the nasal congestion score [(0.82 ± 0.10) points], viscous or purulent nasal discharge score [(1.88 ± 0.25) points], olfactory dysfunction score [(1.12 ± 0.15) points], head and face pain score [(0.40 ± 0.06) points] and nasal endoscopic Lund-Kennedy score [(2.03 ± 0.26) points] in the observation group were significantly lower than those in the control group [(1.94 ± 0.26) points, (2.93 ± 0.37) points, (1.73 ± 0.25) points, (0.62 ± 0.09) points, (4.07 ± 0.47) points, respectively, t = 9.156, 15.056, 13.397, 13.023, 9.156, all P < 0.01]. The ciliary transport rate in the observation group [(4.71 ± 0.56) mm/min] was significantly higher than that in the control group [(3.94 ± 0.51) mm/min, t = 15.056, P < 0.01]. Total effective rate in the observation group was 97.56% (40/41), which was significantly higher than 80.49% (33/41) in the control group ( χ2 = 4.493, P < 0.05). In the control group, one patient had epistaxis, and no adverse reaction was observed in the observation group. Conclusion:Honeysuckle extraction liquid combined with nasal irrigation with 0.9% sodium chloride injection is effective in the treatment of nasosinusitis after radiotherapy for nasopharyngeal carcinoma, can greatly improve the symptoms and signs of patients, and is highly safe.

ObjectiveTo investigate the relationship between the change of circulating endothelial cell (CEC) level and coronary artery lesion (CAL) of Kawasaki disease (KD),and to further explore the method for early diagnosis of KD.MethodsThirty KD children were recruited for study,including 23 children with complete type of KD and seven children with incomplete KD.According to the results of echocardiography,the KD group was divided into CAL group (9 cases) and non-coronary artery lesion (NCAL)group (21 cases).Ten healthy children were enrolled as control group.Double-blind and controlled trial was conducted,and Hladovec method was applied for CEC counting.Results The CEC level was ( 1.09 ±0.60) × 107/L in KD group,which was higher than that of control group [ (0.38 ±0.14) × 107/L],and the difference was statistically significant ( t =2.85,P ＜ 0.01 ).The CEC level in the CAL group [ ( 1.84 ± 0.24) × 107/L] was higher than that of the NCAL group[ (2.01 ±0.38) × 107/L],and the difference was statistically significant ( t =2.24,P ＜ 0.05 ).The CEC level was ( 1.16 ± 0.63 ) × 107/L in the complete type of KD group and (0.83 ± 0.45 ) × 107/L in the incomplete KD group,which showed no significant difference between the two groups ( t =1.86,P ＞ 0.05 ).CondusionCEC level was elevated significantly in the acute phase of KD.The CEC level in CAL group was higher than that of NCAL group in acute phase.CEC level detection may be helpful for the early diagnosis of KD.

Objective To observe the levels of Livin and Caspase-3 in renal tissue of rats following acute paraquat (PQ) poisoning and the intervention effects of ulinastatin (UTI) . Methods Fifty-four Sprague-Dawley (SD) rats were randomly divided into three experimental groups: control group (group A),PQ poisoning group (group B) and UTI group (group C) (n = 18 in each group) . Rats in group B and group C were administered intragastrically with 80 mg/kg PQ, and rats in group C were treated with 100,000U/kg ulinastatin injected intra-psritoneally once a day; and rats in group A were administered intragastrically with the same volume of saline instead of PQ. At 24, 48, 72 hours after poisoning, the levels of Livin in renal tissue were detected by Westen blotting and the levels of Caspase-3 were detected by immunohistochemistry 24, 48, and 72 hours after poisoning, and the histopathological changes of renal tissue were observed at the same time. Results In the group A, the structure of renal tissue was distinct. In the group B, the distinctness of the structure of renal tissue declined significantly, and swelling, edema and vacuolar degeneration were observed 24 h after poisoning, and pathological changes became more and more obvious keeping pace with time elapsing, and sometimes karyopyknosis appeared and celluar structures disappeared with involvement of renal glomerulus and medulla. These pathological changes were significantly lessened in rats of group C. In the group A, there was little Caspase-3 in renal tissue of rats. Twenty-four hours after poisoning, the caspase-3 in renal tissue of rats of group B was found on the membrane and in the kytoplasm of renal tubular epithelial cells of cortical part. Compared with group B, the level of Caspase-3 in renal tissue of rats of group C decreased significantly to lower level (P ＜0. 01 ) . Compared with group A,the levels of Livin in renal tissue in rats of group B and group C increased significantly at all different intervals (P ＜0. 01 ), and as group B was compared with group C, the difference was statistically significant (P ＜0. 01 ) . Conclusions The main pathologyical changes of renal injury induced by PQ are epithelial swelling, vacuole degenerateion and necrosis. Caspase-3 is involved in the process of renal injury. UTI has a protective effect on the renal tissue of rats following paraquat poisoning through up-regulating the level of Livin and down-regulating the level of Caspase-3, however, the regulation mechanism as well as the pathway is still needed to further study.

Objective:To provide a retrospective analysis of the levels of occupational external exposure of radiation workers in Hubei province from 2009 to 2018 in a way to prevent and control its risks.Methods:The external individual doses were surveyed for 50 070 radiation workers between 2009 and 2018 by the effort of the Hubei Provincial Center for Disease Control and Prevention. Under the relevant national standards, the external radiation doses to radiation workers were conducted by using TLDs.Results:The average annual collective effective dose to radiation workers in a 10 years period was 1.93 man·Sv, the median of average annual effective dose of 0.14 mSv ( P25- P75: 0.06-0.30 mSv), and the average annual effective dose of 0.40 mSv. The annual effective doses received by 46 562 workers were less than 1 mSv, accounting for 92.99% of the total monitored workers. The annual effective dose varied dependent on occupational categories, showing a year-by-year decline trend and staying at a low level after 2012. The relative high radiation doses were seen in nuclear medicine and interventional radiology in medical applications, non-destructive testing and well logging in industrial applications, and other types of radiation applications. Conclusions:The average annual effective dose decreased year in a by year manner and kept at a low level. This indicated that the radiological protection measures taken during the 10 years ensure the health of workers. The continuous monitoring result suggest that much more attention should be paid to such categories workers as nuclear medicine, interventional radiology, non-destructive testing, well logging and others through improving radiation protection measures.

Objective To identify the relationship among serum 25-hydroxyvitamin D[25(OH)D] level, chronic inflammation state and malnutrition in maintenance hemodialysis (MHD) patients. Methods The serum 25 (OH)D level of 119 patients on MHD was detected. All the patients were divided into three groups according to the serum 25(OH)D level. Vitamin D deficiency: 25(OH)D ≤ 15 ng/mL, vitamin D insufficiency: 15 ng/mL <25(OH)D ≤ 30 ng/mL, vitamin D normal: 25(OH)D > 30 ng/mL. Inflammatory factor and nutritive index were compared among the three groups. Result The average of serum 25 (OH)D level was 3.4~45.3 ng/mL (22.5~14.8 ng/mL), and the prevalence of 25 (OH)D deficiency and insufficiency was 88.2%. Significant differences existed in age, inflammatory factor (IL-6, TNF-α, CRP) and nutritive index (Alb, PA, SGA) between 25(OH)D deficiency, insufficiency groups and normal group (P<0.05). Conclusion The serum 25(OH)D level is possibly related to the malnutrition in MHD patients. It may inhibit chronic inflammation state , in which it can promote state of nutrition of MHD patients.

Objective To study influences of intervention in pregnant women with positive thyroid autoantibodies on the thyroid function of babies. Methods A total of 55 pregnant women were enrolled with positive thyroid peroxidase antibody (TPOAb) and/or thyroglobulin antibody (TgAb) during prenatal checkup. They were randomly divided into two groups: intervening group( n= 36, newborn group A) was treated with levothyroxine ( L-T4 ), and non-intervening group ( n= 19, newborn group B) was not treated. 30 cases of pregnant women with negative thyroid autoantibodies served as a normal population control group (newborn group N). Serum TSH, TPOAb, TgAb, TT3, TT4, FT3 and FT4 were measured by high-sensitive immunochemiluminescent assay ,and urinary iodine was also examined in the pregnant women. Fetal plasma TSH, TT3, TT4, FT3, and FT4 levels were measured after cutting the umbilical cord from placenta, and repeated measurements were made by 3-4 weeks and 8-10 weeks postpartum. Results At baseline, serum TSH levels of the pregnant women in intervening and nonintervening groups were significantly higher than that in control group ( P＜0.05 ). Non-intervening group had higher TSH and lower TT3, TT4, FT4 compared with the other two groups (P＜0. 05 or P＜0.01 ). The cord blood TSH levels of the neonates in both group B [(7.06 ± 1.31 ) mIU/L] and group A [(6.23 ± 1.26 ) mIU/L] were significantly higher than that of group N [(5.48±1. 17) mIU/L, P＜0.01 and 0. 05]. By 3-4 weeks postpartum,the serum TSH level [(3.21±0.70)mIU/L] in group B was significantly higher than those in group N [(2.72±0.51)mIU/L] and group A [(2.78±0.42) mIU/L, all P＜0.05]. The serum TSH level in group B [(2.99±0.57) mIU/L] was still higher than those in group N [(2.48±0.68) mIU/L] by 8 to 10 weeks postpartum (P＜0.05 ). Multiple stepwise regression analysis revealed that TSH, TPOAb, and urine iodine levels of mothers were independently related to TSH of their infants. Conclusion When differences in thyroid function exist in pregnant women, these differences also reside in their offspring. The thyroid function in neonates correlates with both the thyroid autoantibodies and thyroid function of their mothers.
