Objective:To compare the clinical effect of transaxillary non-inflatable endoscopic surgery and traditional open thyroid surgery in the treatment of PTC. Methods:A retrospective analysis was performed on 342 patients with PTC treated in the Otorhinolaryngology Department of Qilu Hospital of Shandong University from December 2020 to December 2022. There were 73 males and 269 females, aged 16-72 years, who underwent unilateral non-inflatable transaxillary endoscopic thyroid surgery（endoscopic group） and unilateral traditional open thyroid surgery（open group）. There were 108 patients in the endoscopic group and 234 in the open group. Results:The endoscopic group was lower in age（37.1±9.4 vs 43.5±11.2） years and BMI（23.4±3.4 vs 25.7±3.8 ）kg/m² than that in the open group, and the difference was statistically significant（t was 5.53, 5.67 respectively, P<0.01）. There was no significant difference in hospitalization days between the two groups（P>0.05）. The logarithmic curve of the operation time showed a smooth downward trend, and the overall operation time of the endoscopic group was relatively consistent. There was no significant difference in intraoperative blood loss between the endoscopic group（13.3±3.2） mL and the open group（14.7±6.3） mL（P>0.05）, but the operation time（130.1±37.9） min was longer than that in the open group（57.4±13.7） min, and the difference was statistically significant（t=19.40, P<0.01）. There was no significant difference in complications such as temporary recurrent laryngeal nerve injury within 3 days after operation between the two groups（P>0.05）. The aesthetic satisfaction score of the surgical incision and the incision concealment effect score in the endoscopic group were higher than those in the open group, and the difference was statistically significant（P<0.05）. Conclusion:Compared with traditional open thyroidectomy, transaxillary non-inflatable endoscopic thyroidectomy has more advantages in the concealment and aesthetics of postoperative incision. Although the former has longer operation time and more drainage, it is still a safe and feasible surgical method with good postoperative clinical effect.

Objective:To inhibit the Itch gene expression of T-lymphocytes and investigate the immune activity of T lymphocytes using ultrasound-targeted microbubble destruction (UTMD).Methods:T lymphocytes were separated by magnetic bead, and to establish an Itch gene targeted short hairpin RNA (shRNA) plasmid. There were three groups in this study: ①experimental group, Itch-shRNA plasmid-SonoVue microbubbles combined with ultrasound irradiation; ②control group, negative control shRNA plasmid-SonoVue microbubbles combined with ultrasound irradiation; ③blank group, untreated. Forty-eight hours after UTMD transfection, transfection efficiency was detected and analyzed by fluorescence microscopy and flow cytometry, the expression of Itch protein was measured with Western blotting.Seventy-two hours after UTMD transfection, the secretion of interleukin 2 (IL-2) and interferon γ (IFN-γ) in the cell supernatant were measured by enzyme-linked immunosorbent assay (ELISA). One-way ANOVA was used to compare the differences between groups, and LSD- t test was used to compare the differences between groups. Results:The UTMD mediated shRNA transfection rate was 52.3%, and the relative expression levels of Itch protein in the experimental group, control group and blank group were 0.301±0.080, 0.773±0.101 and 0.719±0.090, respectively, and the difference was statistically significant( F=24.441, P<0.01). The Itch gene expression can be effectively suppressed in the experimental group. Seventy-two hours after transfection, the concentrations of IL-2 in the experimental group, control group and blank group were (417.3±37.1)ng/L, (158.7±17.3)ng/L and (147.0±10.2)ng/L, respectively, and the difference was statistically significant( F=118.701, P<0.001) and the concentrations of IFN-γ were (168.3±12.1)ng/L, (74.3±3.7)ng/L and (74.6±7.1)ng/L, respectively, and the difference was statistically significant ( F=126.833, P<0.001). The expression levels of IL-2 and IFN-γ in the experimental group were significantly higher than those in the control group and the blank group. Conclusions:UTMD mediated shRNA transfection can significantly decrease the expression of Itch and promote immune activity of T lymphocyte.

Objective:To evaluate the oncologic and functional outcomes of postcricoid carcinoma treated by surgical treatment, and to summarize our clinical experience in surgical treatment and reconstructive techniques.Methods:Medical files of 45 patients were collected and retrospectively analyzed. The patients received surgical treatments between January 2010 and May 2017 in the Qilu Hospital of Shandong University, including 39 males and 6 females, the age ranged from 41 to 78 years old. T1, T2, T3 and T4 staging tumors represented respectively for 2,13,23 and 7 cases. And cervical metastasis was histologically identified in 33 cases (8 for N1 and 25 for N2). Advanced staging patients (10 in Stage Ⅲ and 30 in Stage Ⅳ) accounted for 88.9% of the cohort, while early staging cases (1 in Stage Ⅰand 4 in Stage Ⅱ) for 10.1%. All patients received cervical lymph node dissection. After tumor excision without compromising margins, hypopharyngeal functions were reconstructed by residual mucosa, pectoralis major myocutaneous flap, laryngotracheal tissue flap or gastric tissue flap, and laryngeal functions were reconstructed by epiglottis, sternohyoid myofascial flap or thyroid perichondrium. Survival rates were analyzed by the Kaplan-Meier method.Results:Postoperatively 23 patients received radiotherapy and 13 patients received chemoradiotherapy. All patients were followed up for more than 3 years. Total 3-year and 5-year survival rates were 60.5% and 49.0%, respectively. Patients obtaining the conservation of laryngeal functions accounted for 44% (20/45) of all cases. The neck lymph node positive rate was 73.3%(33/45), and log-rank test demonstrated that cervical lymph node metastasis was significantly associated with prognosis of patients (χ 2=4.364, P=0.037). Conclusion:Appropriate surgical approaches and excision methods and comprehensive application of flaps are critical to precise tumor excision and reconstruction of laryngeal functions, thereby improving the quality of life of patients with posterior carcinoma.

Objective To study the difference of clinical outcome between late preterm twins (LPT) and late preterm singletons (LPS),and the influence of assisted reproduction technology (ART) or natural conception on the clinical outcomes of LPT.Method The data of late preterm infants born in the Beijing Obstetrics and Gynecology Hospital between January 2016 and January 2018 were retrospectively collected.Infants were assigned to LPT group or LPS group according to twins or singleton status.The differences of the demographic data,morbidity,oxygen therapy rate,respiratory support rate,mortality,hospitalization rate and hospitalization time between LPT and LPS were compared.In order to analyze the effects of different ways of conception on LPT,LPT was further divided into assisted reproduction technology (ART) subgroup and natural pregnancy subgroup.Result A total of 1 824 late preterm infants were included in the study,including 582 cases of LPT and 1 242 cases of LPS.The birth weight and body length of LPT were lower than those ofLPS [(2572±395)gvs.(2614±413)g,P＜0.05;(46.5±1.1)cm vs.(47.5 ± 1.0)cm,P ＜0.01],while the cesarean delivery rate of LPT was higher than that of LPS [90.7％ (528/582) vs.39.9％ (496/1 242),P ＜ 0.01].The incidence of respiratory distress syndrome (RDS) in LPT was higher than that of LPS [5.2％ (30/582) vs.3.6％ (45/1 242),P ＜ 0.05],and the length of hospitalization of LPT was also longer than that of LPS[(8.9 ±3.1)d vs.(7.2 ±2.9)d,P ＜0.01],the differences were statistically significant.There were no significant differences between groups in neonatal pneumonia,apnea,hypoglycemia,sepsis,neonatal necrotizing enterocolitis (NEC),grade Ⅲ ～ Ⅳ intracranial hemorrhage,severe asphyxia,bronchopulmonary dysplasia (BPD),oxygen therapy rate,respiratory support rate and mortality rate.There was also no significant difference between ART subgroup and natural pregnancy subgroup in gestational age,gender,cesarean section rate,birth weight,and birth length (P ＞ 0.05).There was no significant difference in RDS,pneumonia,apnea,hypoglycemia,sepsis,NEC,Ⅲ ～ Ⅳ intracranial hemorrhage,severe asphyxia,BPD,oxygen uptake rate,respiratory support rate,mortality rate and hospitalization time between the two subgroups (P ＞ 0.05).Conclusion The birth weight and birth length of LPT are lower than those of LPS,and the incidence of RDS is higher.The hospitalization time of LPT is also longer than that of LPS.It is necessary to strengthen the high-risk management of twin pregnant women and post-natal management of LPT.

Objective: To evaluate the effectiveness on informational support of the parenting sense of competence and parenting stress in primiparas. Methods: Ninety-five primiparas in the First Affiliated Hospital of Zhengzhou University were recruited from November 2017 to April 2018, mothers of premature infants discharged from hospital from November 2017 to January 2018 were divided into the control group,and which discharged from February 2018 to April 2018 were divided into the experimental group conveniently.Seven cases in the control group and 5 cases in the experimental group dropped out. The control group received routine nursing care, 4 times of informational support were implemented to the mothers of premature infants at the first 4 months after discharged in the experimental group,included team teaching, live demonstration, set up a wechat group, et al. All primiparas were investigated using the Chinese version of Parenting Sense of Competence Scale(C-PSOC) and the Parenting Stress Index-Short Form(PSI-SF) at the 1^th,3^th,6^th month postpartum. Results: At the 6^th month postpartum, total scores of the Chinese version of Parenting Sense of Competence Scale and subscale scores of self-efficacy, satisfaction of the mothers of premature infants were 82.60±4.45, 39.19±3.25, 43.40±3.47, respectively in the experimental group,and the scores were 76.83±7.88, 36.90±4.82, 39.93±5.16, respectively in the control group, the difference between the two groups was statistically significant(t=4.117, 2.541, 3.613, P<0.05). At the 6^th month postpartum,total scores of the Parenting Stress Index-Short Form and subscale scores of parenting distress,parent-child dysfunctional interaction,difficult child of the mothers of premature infants were 80.31±9.50, 28.62±4.54, 23.98±4.91, 26.14±5.15, respectively in the experimental group,and the scores were 87.36±8.58, 32.55±4.88, 25.95±4.15, 28.84±4.88, respectively in the control group,the difference between the two groups was statistically significant(t=-3.568-3.823, P<0.05).

Objective: To summarize clinical experience in surgical treatment of supraglottic carcinoma and reconstructive techniques. Methods: Medical files of 184 patients (173 men, 11 women) were collected and retrospectively analyzed, who underwent surgeries between January 2008 and December 2012 at Qilu Hospital of Shandong University. Among them, T1, T2, T3 and T4 staging tumors accounted respectively for 14.1% (26/184), 41.9%(77/184), 31.5%(58/184) and 12.5%(23/184). Cervical metastasis was histologically identified in 86 cases (98 for N0, 31 for N1 and 55 for N2). Advanced cases (56 cases at stage Ⅲ and 67 at stage Ⅳ), early cases (22 at stage Ⅰ and 39 at stage Ⅱ) accounted respectively for 66.8% and 33.2%. Supraglottic horizontal laryngectomy or total laryngectomy was performed to allow for tumor excision without compromising margins and the tongue flap or sternohyoidmyofascial flap was subsequently used for repairing the defect after removal of tumor. Survival rates were analyzed by the Kaplan-Meier method. Results: Patients receiving conservation laryngeal surgery accounted for 75.5% (139/184). The 3-year and 5-year survival rates for all cases were 84.2% and 70.7%, respectively. Log-rank test demonstrated that cervical lymph node metastasis, primary tumor staging and clinical TNM staging were significantly associated with prognoses of patients (P=0.003, 0.010, 0.035). Dysphagia was not observed in any case and speech function was maintained in petients with partial laryngectomy. Conclusion Adequate pre-operative evaluation, individualized treatment, and comprehensive application of flaps for repair are critical to precise tumor excision and reconstruction of laryngeal functions.

Objective To assess and compare the incidence,clinical characteristics,treatment,and prognosis of acute heart failure patients from different grades hospitals in Beijing.Methods In this prospective internet prognosis registered study (Beijing AHF Registry),a total of 3 335 consecutive patients admitted to 14 emergency departments in Beijing from January 1st 2011 to September 23rd 2012 were enrolled.According to hospital grade,these patients were divided into two groups,349 patients were from secondary hospitals,and 2 956 patients were from tertiary hospitals.Results Among the 3 335 patients,the medium age was 71 (58,79) years,and male accounted for 53.16％.The most common underlying disease were coronary disease (43.27％),hypertension (17.73％),cardiomyopathy (16.07％) etc.The average treatment time in Emergency Department was 66.82 h.The emergency department mortality rate was 3.81％ (127 cases).The 30-day and 1-year cumulative all-cause mortality were 15.3％ and 32.27％,respectively.The 30-day and 1-year cumulative all-cause readmission were 15.64％ and 46.89％,respectively.Compared with patients in tertiary hospitals,patients in secondary hospitals had more onset acute heart failure patients (63.64％ vs.49.93％),shorter emergency department treatment time (12 h vs.41 h),lower discharge rate (3.43％ vs.37.45％) and emergency department mortality(1.58％ vs.4.09％).Compared with those in tertiary hospitals,1-year cumulative all-cause mortality (25.6％ vs.33.2％),cardiovascular disease mortality (20.2％ vs.26.0％),aggravated heart failure mortality (22.4％ vs.28.8％) were lower in secondary hospitals.Following propensity score matching,compared to tertiary hospitals,patients in secondary hospitals showed lower utilization rate of beta-blockers and ACEFARB (4.51％ vs.28.17％,1.41％ vs.9.58％),except the pironolactone.Conclusion Acute heart failure in emergency department is associated with a high mortality rate and readmission rate.There is still a big gap between guidelines recommend medication current treatments for acute heart failure.
