Pituitary thyroid-stimulating hormone(TSH)adenomas is a rare pituitary disorder,accounting for less than 2%of pituitary adenomas.The clinical manifestations primarily include mild to moderate symptoms of hyperthyroidism,corresponding symptoms caused by other anterior pituitary hormone secretion disorders,and symptoms resulting from the mass effect of pituitary tumors.Pituitary TSH adenomas need to be differentiated from primary hyperthyroidism(Graves'disease)and resistance to thyroid hormone(RTH),as misdiagnosis can lead to tumor growth and aggravation of the condition.Currently,with the help of sensitive laboratory tests,imaging examinations,and targeted functional tests,pituitary TSH adenomas can be diagnosed relatively accurately.The preferred treatment is surgical resection.In cases where surgery is not feasible or unsuccessful,radiotherapy or medical therapy can be considered.Long-acting somatostatin analogs can effectively reduce tumor volume and decrease TSH secretion,thereby normalizing free 3,5,3',5'-tetraiodothyronine(FT4)and free 3,5,3'-triiodothyronine(FT3).Early identification and effective treatment are significant for patients with pituitary TSH adenomas.This review summarizes the epidemiology,pathological characteristics,screening objects,clinical manifestations,auxiliary examinations,diagnosis and treatment,follow-up and evaluation of pituitary TSH adenoma,aiming to provide guidance for the clinical diagnosis and treatment of this condition.

Objective:To explore the clinical effect and safety of extended debridement combined with BAM bone-induced artificial bone repair in the treatment of Cierny-Mader type IV osteomyelitis.Methods:From January 2021 to December 2022, 106 patients with Cierny-Mader type IV osteomyelitis who were treated with allogeneic bone mixed with autologous bone in department of orthopedics of Sichuan Orthopedic Hospital were retrospectively selected as the study subjects. Among them, 54 patients who were combined with BAM bone-induced artificial bone mixed with autologous bone repair were included in observation group, and 52 patients who only received allogeneic bone mixed with autologous bone repair were enrolled as control group. The clinical related indicators (bone healing time, fracture healing time), clinical efficacy (Johner-Wruh tibial shaft fracture evaluation standard) at 1 year after surgery, inflammatory factors (white blood cell count (WBC), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), procalcitonin), limb function (American Orthopedic Foot and Ankle Society Ankle-Hindfoot Scale (AOFAS-AH)) and bone healing degree before surgery and at 1 year after surgery were compared between both groups. Chi-square test was used to compare the enumeration data between groups, and the independent sample t test was performed to compare the measurement data with normal distribution between groups.Results:At 1 year after surgery, the clinical healing indicators of bone healing time and fracture healing time and inflammatory factors such as WBC, ESR, CRP and procalcitonin with (21.19±2.16) weeks, (11.35±1.01) weeks, (6.15±0.73)×10 9/L, (9.10±1.05) mm/h, (8.09±1.11) mg/L and (0.05±0.01) μg/L in observation group were significantly shorter or lower than (24.32±2.39) weeks, (12.29±1.27) weeks, (7.86±0.89)×10 9/L, (10.10±1.32) mm/h, (9.26±1.23) mg/L and (0.08±0.01) μg/L in control group,and the differences were statistically significant ( t values were 7.08, 4.23, 10.83, 4.33, 5.15, and 15.44, respectively; all P<0.001). The clinical effective rate (85.19%(46/54)), AOFAS-AH score((84.83±12.17) points) and bone healing probability (94.44%(51/54)) were higher than (67.31%(35/52)), (79.17±11.25) points and 80.77% (42/52) in control group,with statistically significant differences (statistical values were χ2=4.70, t=2.48, and χ2=4.60, respectively; P values were 0.030, 0.015, and 0.032, respectively). Conclusion:Expanded debridement combined with BAM bone-induced artificial bone repair can effectively promote the bone tissue healing in patients with Cierny-Mader type IV osteomyelitis, relieve the inflammatory response, and improve the limb function, and it has good clinical efficacy and high safety.

Although microsurgical vasoepididymostomy (MVE) is an effective treatment for epididymal obstructive azoospermia, some patients may experience delayed patency or suboptimal semen parameters after patency. However, research into patency time, semen quality postpatency, and associated influencing factors remains limited. This study aimed to address these issues by evaluating 181 patients who underwent at least one-sided MVE employing asingle-armed longitudinal intussusception vasoepididymostomy technique, with a follow-up period of over 12 months for 150 patients. The overall patency rate was 75.3%, with 86.0% of patients achieving patency within 6 months following MVE. Unexpectedly, factors such as age, history of epididymitis, duration of surgery, side of anastomosis, sperm motility in epididymal fluid, and the site of anastomosis showed no correlation with patency time. Nonetheless, our univariate and multivariate linear regression analysis indicated that only the site of anastomosis was positively correlated with and could independently predict postoperative total motile sperm count. Therefore, the site of anastomosis might serve as a predictor for optimal postoperative semen quality following the MVE procedure.

Objective:To evaluate the effects of different doses of sivelestat sodium on perioperative acute lung injury (ALI) in the patients undergoing emergency surgery for acute Stanford type A aortic dissection (AAAD).Methods:A total of 120 patients of both sexes, aged 30-64 yr, with body mass index of 18.5-24.9 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅲ or Ⅳ, scheduled for emergency AAAD surgery, were divided into 3 groups using a random number table method: low-dose sivelestat sodium group (SL group), medium-dose sivelestat sodium group (SM group)and high-dose sivelestat sodium group (SH group), with 40 patients in each group. Sivelestat sodium 4.8, 6.0 and 7.2 mg/kg were intravenously infused starting from 10 min before anesthesia until 24 h after surgery in SL, SM and SH groups, respectively. Blood samples from the radial artery were collected for blood gas analysis after anesthesia induction and before skin incision (T 1), immediately after the end of surgery (T 2), at 24 h after surgery (T 3), and 72 h after surgery (T 4), the alveolar-arterial oxygen tension difference (PA-aDO 2), oxygenation index (OI)and respiratory index (RI) were calculated. The duration of postoperative mechanical ventilation, length of stay in the intensive care unit (ICU) and length of postoperative hospital stay were recorded. Central venous blood samples were collected at T 1-T 4 to measure serum concentrations of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6)and IL-8. Peripheral venous blood samples were collected on preoperative day 1 and postoperative days 1 and 3 to measure white blood cell (WBC) count, neutrophil (NEUT) count, neutrophil percentage (NEUT%), and C-reactive protein (CRP) concentration. The occurrence of postoperative pulmonary complications (PPCs)and 90-day all-cause mortality were recorded. Results:Compared with the baseline at T 1, PA-aDO 2 and RI were significantly increased, OI was decreased, and the serum concentrations of TNF-α, IL-6 and IL-8 were increased at T 2-T 4 in all the three groups ( P<0.05). WBC, NEUT, NEUT% and concentrations of CRP were significantly higher on postoperative days 1 and 3 than on 1 day before surgery in the three groups ( P<0.05). Compared with SL and SM groups, PA-aDO 2 and RI were significantly decreased, OI was increased, and the serum concentrations of TNF-α, IL-6 and IL-8 were decreased, the WBC count, NEUT count, NEUT% and concentrations of CRP were decreased, the incidence of postoperative hypercapnia, hypoxemia, emerging lung rales and bronchospasm was decreased, and the duration of postoperative mechanical ventilation and length of intensive care unit stay were shortened( P<0.05), and no significant change was found in the postoperative length of hospital stay and 90-day all-cause mortality rate in SH group ( P>0.05). Conclusions:Sivelestat sodium 7.2 mg/kg can significantly inhibit the inflammatory responses, alleviate perioperative ALI, and improve early prognosis in the patients undergoing AAAD surgery.

Objective:To identify the risk factors for postoperative central nervous system complications (CNSC) developed in pediatric patients undergoing cardiac surgery under cardiopulmonary bypass (CPB) through determining regional cerebral oxygen saturation (rSO 2C) by near-infrared spectroscopy. Methods:A total of 60 pediatric patients with congenital heart disease undergoing elective orthodontic correction surgery under CPB, of American Society of Anesthesiologists physical status Ⅱ or Ⅲ, of both sexes, aged 6-36 months, weighing 5-19 kg, in our hospital from July 2019 to January 2020 were collected.Intraoperative bilateral rSO 2C was monitored continuously by near-infrared spectroscopy.Blood samples were taken from the central vein at 10 min after induction of anesthesia, immediately after CPB, at the end of CPB, on admission to ICU, at 4 and 8 h after entering ICU and at 1, 2 and 3 days after surgery (T 0-8) for determination of the concentrations of serum S100β protein and neuron specific enolase (NSE). At 12 months after surgery, the Pediatric Cerebral Performance Category (PCPC) score was used to evaluate the prognosis of neurological function.The patients were divided into 2 groups according to whether CNSC occurred: CNSC group and non-CNSC group.Multivariate logistic regression analysis was used to identify the risk factors for development of postoperative CNSC in pediatric patients undergoing cardiac surgery under CPB. Results:Two patients were excluded from the study.Eighteen cases developed postoperative CNSC, and the incidence was 31.0%.Compared with group non-CNSC, the minimal rSO 2 was significantly decreased, the maximal difference between pulse oxygen saturation and rSO 2C (da-rSO 2C) was increased, duration of reduction in rSO 2>25% during CPB, duration of rSO 2C<40% during CPB and duration of da-rSO 2C>50% during CPB were prolonged, and concentrations of serum S100β protein and NSE were increased at T 2-T 8 in group CNSC ( P<0.05). The results of logistic regression analysis showed that prolonged duration of reduction in rSO 2C>25% during CPB, prolonged duration of rSO 2C<40% during CPB and prolonged duration of da-rSO 2C>50% during CPB were risk factors for development of postoperative CNSC. Conclusion:Prolonged duration of reduction in rSO 2C>25% during CPB, prolonged duration of rSO 2C<40% during CPB and prolonged duration of da-rSO 2C>50% during CPB are the risk factors for postoperative CNCS developed.

Objective:To summarize the efficacy of general anesthesia for percutaneous pulmonary valve implantation (PPVI).Methods:The clinical data of 6 patients underwent PPVI under general anesthesia in Children′s Heart Center of Henan Provincial People′s Hospital from December 2017 to January 2020 were retrospectively analyzed.Systolic blood pressure, diastolic blood pressure, heart rate, central venous pressure, SpO 2 and regional cerebral oxygen saturation were recorded before anesthesia induction (T 1), after anesthesia induction (T 2), before beginning of surgery (T 3), before pulmonary valve implantation (T 4), during pulmonary valve implantation (T 5), immediately after pulmonary valve implantation (T 6) and when the patients left the operating room (T 7). Right ventricular systolic pressure, diastolic pressure, pulmonary artery systolic pressure and diastolic pressure were recorded at T 4 and T 6.The development of related complications during operation and the cardiac, liver and kidney functions before and after operation were recorded.The postoperative extubation time, intensive care unit stay time and hospital stay time were recorded. Results:Six patients (3 males, 3 females), aged (16±4) yr, weighing (41±12) kg, were analyzed.Compared with the value at T 1-4 and T 6, 7, systolic blood pressure, diastolic blood pressure, heart rate, regional cerebral oxygen saturation and SpO 2 were significantly decreased at T 5 ( P<0.05). Compared with the value at T 1-5, central venous pressure was significantly decreased at T 6, 7 ( P<0.05). Compared with the value at T 4, right ventricular diastolic pressure was significantly decreased, and pulmonary artery diastolic pressure was increased at T 6 ( P<0.05). No anesthesia- and surgery-related serious complications occurred among the patients.One patient was transferred to the ward after extubation in the operating room, and 5 patients were transferred to the intensive care unit after operation.All 6 patients were discharged successfully and entered the follow-up stage. Conclusion:General anesthesia provides better efficacy when used for PPVI, and hemodynamic monitoring of pulmonary circulation and systemic circulation should be strengthened during pulmonary valve implantation to maintain circulation stable.

Objective: To identify the risk factors for postoperative hyperlactatemia in the patients with type A aortic dissection. Methods: Medical records of patients with type A aortic dissection who underwent cardiovascular surgery from January 2012 to October 2017 were retrospectively collected.The patients were divided into hyperlactatemia group and non-hyperlactatemia group according to the occurrence of hyperlactatemia (blood lactic acid ≥6 mmol/L) at 8 h after surgery.The variables of which P values were less than 0.05 in univariate analysis would enter the logistic regression analysis to stratify the risk factors for postoperative hyperlactatemia in this type of patients. Results: A total of 295 patients were included, of which 80 cases developed postoperative hyperlactatemia, and the incidence was 27.1%.Logistic regression analysis showed that preoperative acute pericardial tamponade, intraoperative deep hypothermic circulatory arrest time>35 min) and massive transfusion of blood (>1 000 ml) within 8 h after operation were independent risk factors for postoperative hyperlactatemia in the patients with type A aortic dissection. Conclusion Preoperative acute pericardial tamponade, intraoperative deep hypothermic circulatory arrest time>35 min and massive transfusion of blood (>1 000 ml) within 8 h after operation are independent risk factors for postoperative hyperlactatemia in the patients with type A aortic dissection.

Objective: To evaluate the effect of manual decocting and machine decocting on the chemical constituents in Bazhentang based on non-targeted metabolomics, and to find the differential chemical constituents of these two decocting methods. Method: Bazhentang was boiled by standardized manual decocting and machine decocting methods,respectively. Orthogonal partial least square-discriminate analysis(OPLS-DA) and other multivariate statistical methods, combined with variable importance in the projection(VIP) value and t-test, were employed to analyze the effect of two decocting methods on the chemical constituents in Bazhentang. The differential chemical constituents were analyzed by UPLC-LTQ-Orbitrap MS under positive and negative ion modes,mobile phase was acetonitrile-0.1%formic acid aqueous solution for gradient elution,the scanning range was m/z 50-1 500. Result: Under the positive and negative ion modes of high-resolution mass spectrometry, a total of 87 differential components were found,40 of them were identified according to the mass spectrometry data and literature reports, including senkyunolide A, glycyrrhizin, ferulic acid, etc. Conclusion: Based on the analysis of color and chemical compositions of Bazhentang, there are obvious differences between the standardized manual decocting and machine decocting. If the advantages of these two methods are combined,a standardized decoction process can be established on the basis of maintaining the advantages of manual decocting, the effectiveness of traditional Chinese medicine decoction will be maximized and it will be convenient for patients to take it.
