Objective:To investigate the therapeutic effects of different surgical methods on papillary thyroid carcinoma of the isthmus (PTCI) and their effects on parathyroid function and thyroglobulin.Methods:Eighty patients with PTCI who underwent treatment in Zhejiang Xin'an International Hospital from January 2016 to January 2021 were included in this study. They were randomly allocated to undergo ipsilateral lobectomy with removal of the isthmus combined with ipsilateral central neck lymph node dissection (group A, n = 40) or total thyroidectomy combined with ipsilateral central neck lymph node dissection (group B, n = 40). We compared intraoperative and postoperative conditions, complications, and hypoparathyroidism between the two groups. We also compared serum thyroglobulin level measured before and 3 days after surgery between the two groups. Results:Operative time was significantly shorter in group A than in group B [(78.95 ± 13.52) minutes vs. (104.23 ± 27.38) minutes, t = -5.23, P < 0.05]. Intraoperative blood loss was significantly less in group A than in group B [(52.32 ± 6.59) mL vs. (75.41 ± 9.98) mL, t = -12.21, P < 0.05]. There were no significant differences in voice handicap index and reflux symptom index scores between the two groups (both P > 0.05). The incidence of complications was significantly lower in group A than in group B (10.00% vs. 30.00%, χ2 = 5.00, P < 0.05). The incidence of hypoparathyroidism was significantly lower in group A than in group B (7.50% vs. 27.50%, χ2 = 5.54, P < 0.05). At 3 days after surgery, serum thyroglobulin level was significantly lower in group A than in group B [(0.82 ± 0.17) μg/L vs. (1.26 ± 0.23) μg/L, t = -9.73, P < 0.05]. Conclusion:Ipsilateral lobectomy with removal of the isthmus combined with ipsilateral central neck lymph node dissection is more effective on PTCI than total thyroidectomy combined with ipsilateral central neck lymph node dissection. The former has little effect on parathyroid function and can reduce serum thyroglobulin level. The study is highly innovative and scientific.

OBJECTIVETo investigate levels of antibodies against type A and type C influenza viruses and those against the 2009 H1N1 influenza A virus (before and after the 2009 H1N1 pandemic) among residents in Wuxi. To compare levels of antibodies against the 2009 H1N1 influenza virus (one year after the pandemic) in the unvaccinated population with those in the population who received vaccine.

METHODSSerum samples were collected from subjects (aged 1-60 years) during September 2008 to May 2009, and during September 2010 to January 2011. Also collected were serum samples from adults who had received vaccines for pandemic (H1N1) 2009 for one year. Antibody response to influenza viruses was measured using hemagglutination inhibition (HI) assay. Seropositivity rate, seroprotection rate and geometric mean titer (GMT) were compared for each age group during different periods.

RESULTSBefore the outbreak of the 2009 H1N1 pandemic, seropositivity rate, seroprotection rate and GMT among the study subjects in were 2.86% (4/140), 0.71% (1/140) and 5.23, respectively. One year after the outbreak, seropositivity rate, seroprotection rate and GMT among the study subjects were 66.33%, 37.76% and 19.17, respectively. Among them, adult subjects showed 50.00% seropositivity rate, 19.44% seroprotection rate and 13.09 GMT, while adult subjects who had received vaccine for one year showed 61.36% seropositivity rate, 22.73% seroprotection rate and 14.14 GMT. No significant difference was observed between these two populations (P > 0.05 for all three indexes). Furthermore, before the outbreak of the 2009 H1N1 pandemic, levels of antibodies against seasonal influenza viruses among the study subjects were as follows: for H1N1 virus, seropositivity rate, seroprotection rate and GMT were 55.00%, 35.00% and 16.90, respectively; for H3N2 virus, seropositivity rate, seroprotection rate and GMT were 86.40%, 84.30% and 58.56, respectively.

CONCLUSIONOne year after the 2009 H1N1 influenza A virus had spread to Wuxi, the population levels of antibodies against this virus have approached those against seasonal influenza viruses, as reflected by seropositivity rates, seroproection rates and GMT. Moreover, considerable levels of antibodies against seasonal influenza viruses were observed in populations, indicating no seasonal influenza outbreak would occur recently.

Objective To estimate the rates due to influenza-associated-excess-hospitalization in children aged 0-14 years in Wuxi city,Jiangsu province in 2005-2010. Methods We collected data on hospitalization due to influenza,pneumonia and other respiratory diseases from fourteen 2nd level or above hospitals in Wuxi,as well as data on influenza virological surveillance in southern China to fit the negative binomial regression models,to estimate the rate on influenza-associated-excess hospitalization. Results During 2005-2010,an average annual hospitalization rate appeared as 91.6‰(79.2‰-99.3‰). Among the total hospitalization eases,respiratory diseases accounted for 54.2%,while both influenza and pneumonia accounted for 38.1%. The average annual influenza-associated-excess-hospitalization rates due to influenza and pneumonia appeared as 1.28‰(95%CI:0.29‰-4.84‰),while 2.18‰(95%CI:0.61‰-6.79‰) due to respiratory diseases. In 2009,A(H1N1)pdm induced influenza pandemic caused 993 excess hospitalizations due to influenza/pneumonia and 1 042 excess hospitalizations due to respiratory diseases,with rates as 1.14‰ and 1.20‰ respectively. Conclusion Both seasonal and pandemic A(H1N1)pdm influenza caused considerable burden on hospitalization in children aged 0-14 years in Wuxi.

The aim of the present study was to investigate the effect of salidroside (Sal) on inflammatory activation induced by lipopolysaccharide (LPS) in the co-culture of rat alveolar macrophages (AM) NR 8383 and type II alveolar epithelial cells (AEC II) RLE-6TN. CCK-8 colorimetric method was used to detect cell proliferation percentage. The enzyme-linked immunosorbent assay (ELISA) was used to determine the content of tumor necrosis factor alpha (TNF-α), macrophage inflammatory protein-2 (MIP-2) and interleukin-10 (IL-10) in the supernatant. Western blot was used to examine the expression levels of phosphorylated AKT (p-AKT) and total AKT protein. The results showed that pretreatment of RLE-6TN cells or co-culture of RLE-6TN and NR 8383 cells with 32 and 128 µg/mL Sal for 1 h, followed by continuous culture for 24 h, significantly increased the cell proliferation (P < 0.05). Compared with control group, 32 and 128 µg/mL Sal pretreatment significantly increased the ratio of p-AKT/AKT in RLE-6TN cells (P < 0.05). Pretreatment of 32 µg/mL Sal not only inhibited the secretion of TNF-α and MIP-2 by NR 8383 cells induced by LPS (P < 0.05), but also enhanced the inhibitory effect of RLE-6TN and NR 8383 cells co-culture on the secretion of TNF-α and MIP-2 by NR 8383 cells induced by LPS (P < 0.05). In addition, 32 µg/mL Sal pretreatment promoted LPS-induced IL-10 secretion by NR 8383 cells (P < 0.05), and enhanced the promoting effect of co-culture of RLE-6TN and NR 8383 cells on the IL-10 secretion by LPS-induced NR 8383 cells (P < 0.05). In conclusion, Sal may directly inhibit LPS-induced inflammatory activation of AM (NR 8383), promote the proliferation of AEC II (RLE-6TN) through PI3K/AKT signaling pathway, and enhance the regulatory effect of AEC II on LPS-induced inflammatory activation of AM.

OBJECTIVE: To investigate the effect of EBV-DNA copy number on the prognosis of patients with EBV positive lymphoma. METHODS: Clinical data of 109 patients diagnosed as EBV positive lymphoma in Tianjin Medical University Cancer Institute and Hospital from January 2010 to January 2020 were enrolled and analyzed retrospectively. Kaplan-Meier analysis was used for survival analysis, Log-rank was used to compare the clinical characteristics between the patients in different groups, and Cox regression was used for multivariate analysis. RESULTS: Among the 109 patients with EBV-positive lymphoma, the medium age were 56 (range 15 to 83) years old. 29 patients at Ann Arbor stage I-II while 80 patients at stage III-IV. The average value of EBV-DNA was 1 023 510 IU/ml, 7 patients were higher than the average value, while 102 patients were lower. KM survival analysis showed that OS and PFS in patients with EBV-DNA above average level were shorter than those in patients with EBV-DNA below average level (OS: P=0.048, PFS: P=0.001), EBV-DNA copy number was a factor affecting the prognosis of patients. In addition, LDH level showed positive correlation with EBV-DNA copy number (r=0.650), which was also one of the factors affecting OS (P=0.053). CONCLUSION EBV-DNA copy number and LDH level can influence the prognosis of EBV positive lymphoma patients. Therefore, detection of EBV-DNA copy number in peripheral blood is important for evaluate the prognosis the patients.

OBJECTIVE: The study explores the effects of electroacupuncture (EA) at the governing vessel (GV) on proteomic changes in the hippocampus of rats with cognitive impairment. METHODS: Healthy male rats were randomly divided into 3 groups: sham, model and EA. Cognitive impairment was induced by left middle cerebral artery occlusion in the model and EA groups. Rats in the EA group were treated with EA at Shenting (GV24) and Baihui (GV20) for 7 d. Neurological deficit was scored using the Longa scale, the learning and memory ability was detected using the Morris water maze (MWM) test, and the proteomic profiling in the hippocampus was analyzed using protein-labeling technology based on the isobaric tag for relative and absolute quantitation (iTRAQ). The Western blot (WB) analysis was used to detect the proteins and validate the results of iTRAQ. RESULTS: Compared with the model group, the neurological deficit score was significantly reduced, and the escape latency in the MWM test was significantly shortened, while the number of platform crossings increased in the EA group. A total of 2872 proteins were identified by iTRAQ. Differentially expressed proteins (DEPs) were identified between different groups: 92 proteins were upregulated and 103 were downregulated in the model group compared with the sham group, while 142 proteins were upregulated and 126 were downregulated in the EA group compared with the model group. Most of the DEPs were involved in oxidative phosphorylation, glycolipid metabolism and synaptic transmission. Furthermore, we also verified 4 DEPs using WB technology. Although the WB results were not exactly the same as the iTRAQ results, the expression trends of the DEPs were consistent. The upregulation of heat-shock protein β1 (Hspb1) was the highest in the EA group compared to the model group. CONCLUSION EA can effect proteomic changes in the hippocampus of rats with cognitive impairment. Hspb1 may be involved in the molecular mechanism by which acupuncture improves cognitive impairment.
