Objective:To analyze the clinicopathological features of solitary papillary thyroid isthmus carcinoma (SPTIC) and the therapeutic effect and prognosis of different surgical methods.Methods:A total of 161 patients with SPTIC who underwent surgical treatment in the Department of Thyroid Surgery of the First Hospital of Jilin University from Dec. 2012 to Oct. 2021 were selected. Gender, age, body mass index and pathology of the patients were collected and the clinicopathological characteristics of SPTIC were analyzed. They were divided into three groups according to different surgical methods: group A underwent isthmic excision, group B underwent extended isthmic excision, and group C underwent total thyroidectomy. There were 47 patients in group A (8 males and 39 females with an average age of 42.6±9.1 years), 50 patients in group B (11 males and 39 females with an average age of 45.3±11.3 years), and 64 patients in group C (10 males and 54 females with an average age of 46.9±11.4 years). The clinicopathological features and therapeutic effect of the three groups were compared by ANOVA, multiple local rank sum test, χ2 test or Fisher's exact probability method, and the recurrence rate and recurrence free survival (RFS) of the three groups were compared after a follow-up of 6 to 126 months. Results:Among the 161 patients with SPTIC, 132 (82.0%) were female, 130 (80.7%) were younger than 55 years old, BMI (25.1±3.6) kg/m 2, 124 (77.0%) were combined with capsule invasion. There were 53 cases (32.9%) with central lymph node metastasis (CLNM). Subgroup analysis showed that the proportion of males in patients with tumor diameter > 1 cm, the proportion of patients with BMI≥26.0 kg/m 2, the rate of capsular invasion, the rate of extrandular invasion and the rate of CLNM were higher (30.0% vs. 14.0%, P=0.023; 60.0% vs. 33.9%, P=0.004; 97.5% vs. 70.2%, P< 0.001; 42.5% vs. 9.9%, P<0.001; 50.0% vs. 27.3%, P=0.008) ; The CLNM rate was higher in male patients with BMI≥26.0 kg/m 2 and tumor diameter > 1 cm (28.3% vs. 13.0%, P=0.017; 52.8% vs. 34.3%, P=0.024; 37.7% vs. 18.5%, P=0.008). Compared with groups A and B, group C had longer hospitalization days, higher hospitalization costs, longer operation time, more postoperative drainage flow and higher incidence of postoperative hypoparathyroidism, and the differences were statistically significant (all P< 0.05). Groups A and B were similar in all aspects, with no statistical significance ( P> 0.05 for all). During the follow-up, 3 patients in both group A and B relapsed, while no patients in group C relapsed, and there were no statistically significant differences in the recurrence rate ( P=0.059) or RFS ( P=0.082) among the three groups. Conclusions:The majority of SPTIC were microcarcinomas, but the incidence of tumor combined with capsule invasion was higher, and the tumor size of more than 1 cm was more invasive (capsule invasion rate and extrathyroid invasion rate were higher). SPTIC should be treated as conservatively as possible (isthmic excision or enlarged isthmic excision) .

Objective:To explore the significance of CAS-R-2 frameless brain stereotactic apparatus assisted trepanation and drainage in the treatment of hypertensive basal ganglia cerebral hemorrhage.Methods:The clinical data of 60 patients with hypertensive basal ganglia cerebral hemorrhage, who underwent CAS-R-2 frameless brain stereotactic apparatus assisted trepanation and drainage in Beijing Luhe Hospital, Capital Medical University from January 2018 to December 2022, were retrospectively analyzed. The surgical related indexes and adverse reactions were recorded. The patients were followed up for 6 months, and the prognosis was evaluated using the Glasgow outcome score (GOS).Results:A total of 60 cases of CAS-R-2 frameless brain stereotactic apparatus assisted trepanation and drainage were all successfully performed, and the operation time was (53 ± 18) min. There were 2 cases (3.3%) of postoperative puncture path hematoma, which were completely resolved with conservative treatment. The expansion of postoperative intracerebral hematoma was not observed. The drainage tube retention after operation ≤2 d was in 44 cases (73.3%), and the drainage tube retained for 3 to 4 d was in 16 cases (26.7%), all of them had no intracranial infection after operation. Fifteen cases (25.0%) were complicated with severe pneumonia after operation, and 2 cases (3.3%) died due to severe pneumonia combined with multiple organ failure. Follow up at 6 months after operation, 17 cases (28.3%) were good, 19 cases (31.7%) had mild disability, 16 cases (26.7%) had severe disability, 6 cases (10.0%) had vegetative survival status, and 2 cases (3.3%) died.Conclusions:The CAS-R-2 frameless brain stereotactic instrument assisted trepanation and drainage for the treatment of hypertensive basal ganglia cerebral hemorrhage has the characteristics of simple operation, accurate positioning, minimal trauma, and fewer complications. It is a safe and effective method for treating hypertensive basal ganglia cerebral hemorrhage.

Objective:To examine the potential of combining the blood urea nitrogen(BUN)/albumin(ALB)ratio(BAR)with soluble growth stimulation expressed gene 2(sST2)as an early warning indicator for myocardial injury in elderly patients with sepsis in the emergency intensive care unit(EICU).Methods:The clinical data of elderly patients with sepsis admitted to the EICU of the Emergency Medicine Department at Harrison International Peace Hospital of Hebei Medical University from August 2018 to August 2022 were prospectively analyzed.The patients were divided into two groups based on the presence or absence of myocardial injury: the myocardial injury group and the non-myocardial injury group.The general clinical data and laboratory indexes of the two groups were compared, and the BAR was calculated.The correlation between BAR and myocardial injury in elderly patients with sepsis was analyzed.Binary Logistic regression analysis was used to identify the risk factors for myocardial injury in elderly patients with sepsis in the EICU.MedCalc software was employed to determine the early warning value of the combined sST2 and BAR for myocardial injury in elderly patients with sepsis in the EICU.Results:A total of 165 cases were analyzed, with 106 cases(64.24%)showing myocardial injury.It was found that elderly sepsis patients with lung and abdominal infection were more likely to experience myocardial injury( P<0.05 for all).In comparison to the group without myocardial injury, the levels of inflammatory markers such as white blood cell count(WBC), neutrophil to lymphocyte ratio(NLR), lactic acid, and procalcitonin(PCT), as well as combined markers BAR and sST2, were higher in elderly sepsis patients with myocardial injury upon admission.Correlation analysis results revealed significant positive correlations between BAR and lactic acid, PCT, and C-reactive protein(CRP)within 24 hours of admission to EICU in elderly sepsis patients with myocardial injury.Among these correlations, the strongest was observed between BAR and PCT( r=0.417, P<0.001).Additionally, BAR exhibited a positive correlation with acute physiology and chronic health evaluation scoring system(APACHEⅡ)scores( r=0.241, P=0.002).Furthermore, BAR showed positive correlations with myocardial injury markers sST2 and cTnI( r=0.327, 0.307, P<0.05 for all).Logistic regression analysis revealed that septic shock( OR=2.406, P=0.008), decreased left ventricular ejection fraction(EF)( OR=0.939, P=0.015), BAR( OR=2.205, P=0.044), lactic acid( OR=1.137, P=0.014), and sST2 elevation( OR=1.016, P=0.020)were identified as independent risk factors for predicting myocardial injury in elderly patients with sepsis.The results of ROC analysis indicated that BAR had a high early warning value for the occurrence of myocardial injury in elderly patients with EICU sepsis[area under curve(AUC)0.651, P<0.05], with an optimal cut-off value of 0.32(sensitivity 77.4%, specificity 60.2%).Furthermore, the combined detection of BAR and sST2 demonstrated a higher early warning value for the occurrence of myocardial injury in elderly patients with sepsis(AUC 0.697, P<0.05).The mortality rate of patients with myocardial injury below a cut-off value of 0.32 was 36.00%(9/25), while the mortality rate of patients with myocardial injury equal to or above 0.32 was 66.67%(54/81).The difference between the two groups was statistically significant( χ2=8.624, P=0.003). Conclusions:Both BAR and sST2 are considered independent risk factors for myocardial injury in elderly patients with sepsis.The combined detection of BAR and sST2 provides a more accurate prediction for the occurrence of myocardial injury in these patients.

BACKGROUND: LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer. METHODS: We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels. RESULTS: On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]). CONCLUSION: LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile. TRIAL REGISTRATION ClinicalTrials.gov, NCT04563936.

A retrospective study was conducted on data of 23 patients with pancreatic duct diseases who were underwent peroral pancreatoscopy (POPS) at the Pancreatic Center of the First Affiliated Hospital of Nanjing Medical University from August 2020 to October 2022. The intraoperative observation, postoperative complications, and the diagnosis and treatment of POPS for pancreatic duct diseases were analyzed. All patients underwent POPS and achieved technical success. Among them, 7 patients were diagnosed as having intraductal papillary mucinous neoplasm of pancreas and 3 pancreatic malignant tumor. Eight patients with pancreatolithiasis accepted laser or eletrohydraulic lithotripsy under POPS. Abdominal pain improved in 2 patients with chronic pancreatitis after treatment. Melena disappeared in 2 patients with pancreatic duct hemorrhage or pancreatic enterostomy inflammation after conservative treatment. The symptom of 1 patient with pancreatic enterostomy stenosis improved after balloon dilation. There was no complication in the 23 patients, and the operation time was 35-90 min. The results indicate POPS is safe, effective with distinctive advantages in the diagnosis and treatment for pancreatic duct diseases.

Objective:To evaluate the safety of double and a half layered esophagojejunal anastomosis in radical gastrectomy.Methods:This prospective, multi-center, single-arm study was initiated by the Affiliated Cancer Hospital of Zhengzhou University in June 2021 (CRAFT Study, NCT05282563). Participating institutions included Nanyang Central Hospital, Zhumadian Central Hospital, Luoyang Central Hospital, First Affiliated Hospital of Henan Polytechnic University, First Affiliated Hospital of Henan University, Luohe Central Hospital, the People's Hospital of Hebi, First People's Hospital of Shangqiu, Anyang Tumor Hospital, First People's Hospital of Pingdingshan, and Zhengzhou Central Hospital Affiliated to Zhengzhou University. Inclusion criteria were as follows: (1) gastric adenocarcinoma confirmed by preoperative gastroscopy;(2) preoperative imaging assessment indicated that R0 resection was feasible; (3) preoperative assessment showed no contraindications to surgery;(4) esophagojejunostomy planned during the procedure; (5) patients volunteered to participate in this study and gave their written informed consent; (6) ECOG score 0–1; and (7) ASA score I–III. Exclusion criteria were as follows: (1) history of upper abdominal surgery (except laparoscopic cholecystectomy);(2) history of gastric surgery (except endoscopic submucosal dissection and endoscopic mucosal resection); (3) pregnancy or lactation;(4) emergency surgery for gastric cancer-related complications (perforation, hemorrhage, obstruction); (5) other malignant tumors within 5 years or coexisting malignant tumors;(6) arterial embolism within 6 months, such as angina pectoris, myocardial infarction, and cerebrovascular accident; and (7) comorbidities or mental health abnormalities that could affect patients' participation in the study. Patients were eliminated from the study if: (1) radical gastrectomy could not be completed; (2) end-to-side esophagojejunal anastomosis was not performed during the procedure; or (3) esophagojejunal anastomosis reinforcement was not possible. Double and a half layered esophagojejunal anastomosis was performed as follows: (1) Open surgery: the full thickness of the anastomosis is continuously sutured, followed by embedding the seromuscular layer with barbed or 3-0 absorbable sutures. The anastomosis is sutured with an average of six to eight stitches. (2) Laparoscopic surgery: the anastomosis is strengthened by counterclockwise full-layer sutures. Once the anastomosis has been sutured to the right posterior aspect of the anastomosis, the jejunum stump is pulled to the right and the anastomosis turned over to continue to complete reinforcement of the posterior wall. The suture interval is approximately 5 mm. After completing the full-thickness suture, the anastomosis is embedded in the seromuscular layer. Relevant data of patients who had undergone radical gastrectomy in the above 12 centers from June 2021 were collected and analyzed. The primary outcome was safety (e.g., postoperative complications, and treatment). Other studied variables included details of surgery (e.g., surgery time, intraoperative bleeding), postoperative recovery (postoperative time to passing flatus and oral intake, length of hospital stay), and follow-up conditions (quality of life as assessed by Visick scores).Result:[1] From June 2021 to September 2022,457 patients were enrolled, including 355 men and 102 women of median age 60.8±10.1 years and BMI 23.7±3.2 kg/m2. The tumors were located in the upper stomach in 294 patients, mid stomach in 139; and lower stomach in 24. The surgical procedures comprised 48 proximal gastrectomies and 409 total gastrectomies. Neoadjuvant chemotherapy was administered to 85 patients. Other organs were resected in 85 patients. The maximum tumor diameter was 4.3±2.2 cm, number of excised lymph nodes 28.3±15.2, and number of positive lymph nodes five (range one to four. As to pathological stage,83 patients had Stage I disease, 128 Stage II, 237 Stage III, and nine Stage IV. [2] The studied surgery-related variables were as follows: The operation was successfully completed in all patients, 352 via a transabdominal approach, 25 via a transhiatus approach, and 80 via a transthoracoabdominal approach. The whole procedure was performed laparoscopically in 53 patients (11.6%), 189 (41.4%) underwent laparoscopic-assisted surgery, and 215 (47.0%) underwent open surgery. The median intraoperative blood loss was 200 (range, 10–1 350) mL, and the operating time 215.6±66.7 minutes. The anastomotic reinforcement time was 2 (7.3±3.9) minutes for laparoscopic-assisted surgery, 17.6±1.7 minutes for total laparoscopy, and 6.0±1.2 minutes for open surgery. [3] The studied postoperative variables were as follows: The median time to postoperative passage of flatus was 3.1±1.1 days and the postoperative gastrointestinal angiography time 6 (range, 4–13) days. The median time to postoperative oral intake was 7 (range, 2–14) days, and the postoperative hospitalization time 15.8±6.7 days. [4] The safety-related variables were as follows: In total, there were 184 (40.3%) postoperative complications. These comprised esophagojejunal anastomosis complications in 10 patients (2.2%), four (0.9%) being anastomotic leakage (including two cases of subclinical leakage and two of clinical leakage; all resolved with conservative treatment); and six patients (1.3%) with anastomotic stenosis (two who underwent endoscopic balloon dilation 21 and 46 days after surgery, the others improved after a change in diet). There was no anastomotic bleeding. Non-anastomotic complications occurred in 174 patients (38.1%). All patients attended for follow-up at least once, the median follow-up time being 10 (3–18) months. Visick grades were as follows: Class I, 89.1% (407/457); Class II, 7.9% (36/457); Class III, 2.6% (12/457); and Class IV 0.4% (2/457).Conclusion:Double and a half layered esophagojejunal anastomosis in radical gastrectomy is safe and feasible.

Objective:To investigate the relationship between serum vascular endothelial growth factor (VEGF) levels and white matter high signal and non-dementia vascular cognitive dysfunction in patients with cerebral small vascular disease (CSVD).Methods:Total 106 patients with CSVD who were admitted to the Department of Neurology of the First Affiliated Hospital of Xinxiang Medical College from April 2019 to December 2020 were enrolled.They were divided into vascular cognitive impairment no dementia group (VCIND group, n=47) and no vascular cognitive impairment group (N-VCI group, n=59)according to mini-mental assessment scale (MMSE), Montreal cognitive assessment (MoCA) scale and activity of daily living scale (ADL). Serum VEGF levels were detected by enzyme-linked immunosorbent assay (ELISA). The baseline data, serum VEGF levels, MoCA score and Fazekas score were compared between the two groups.The correlation between serum VEGF level and white matter high signal and cognitive function was analyzed.SPSS 19.0 software was used for data processing.The statistical methods were t-test, Chi square test, nonparametric test, Logistic regression analysis, Pearson correlation analysis and Spearman correlation analysis. Results:There were significant differences in serum VEGF level((464.18±114.58)pg/mL, (414.17±45.80)pg/mL, F=22.880), MoCA score((13.07±6.48), (20.17±4.06), F=17.920) and Fazekas score (4(3, 5), 3(1, 3), Z=-4.189)between the two groups (all P<0.05). The level of VEGF( β=0.008, OR=1.008, 95% CI=1.001-1.015, P<0.05) was the influencing factor of cognitive function in patients with CSVD .The level of VEGF was negatively correlated with the total score of MoCA, attention and calculation power, and orientation ability ( r=-0.345, -0.373, -0.445, all P<0.05) and it was positively correlated with the total Fazekas score and the Fazekas score of paraventricular and deep white matter ( r=0.392, 0.495, 0.302, all P<0.05). There was a linear trend between the high signal grade of paraventricular and deep white matter and VCIND (both P<0.05). Conclusion:Serum VEGF level is correlated with cognitive function and white matter hyperintensity in patients with CSVD.The increase of VEGF level may be a factor reflecting cognitive dysfunction.In addition, with the increase of white matter hyperintensity level, the risk of VCIND in CSVD is increased.

Objective:To explore the clinical characteristics of elderly patients with type 2 diabetes mellitus (T2DM) complicated with coronary atherosclerotic heart disease (CHD) and analyze the risk factors of CHD in patients with T2DM.Methods:Using the method of retrospective cohort study, 406 elderly male patients with T2DM (≥75 years old) admitted to Xinhua Hospital Affiliated to Shanghai Jiaotong University from January 2017 to January 2020 were selected and divided into T2DM without CHD group (165 cases) and T2DM with CHD group (241 cases).

The total bilirubin(TBil)(8.80(6.60, 11.60) μmol/L), glomerular filtration rate(GFR)((76.49±29.80) mL/(min·1.75 m 2)) in T2DM with CHD group were lower than those in T2DM without CHD group (11.25(8.23, 15.28) μmol/L, (91.81±28.31) mL/(min·1.75 m 2)), the differences were statistically significant( Z=2.304, t=5.126; all P<0.001). The total cholesterol((3.84±0.85) mmol/L), low-density lipoprotein cholesterol(LDL-C)((2.12±0.68 ) mmol/L) in T2DM with CHD group were lower than those in T2DM without CHD group((4.10±1.00) mmol/L, (2.45±0.85) mmol/L), the differences were statistically significant( t=2.828, 4.156; all P<0.05). The rate of starting lipid-lowering and stable plaque treatment in T2DM with CHD group (82.57%(199/261))was higher than that in T2DM without CHD group(42.42%(70/165)), and the difference was statistically significant (χ 2=70.614, P<0.001). Influenced by lipid-lowering therapy, the total cholesterol and LDL-C in T2DM patients with CHD were significantly decreased.Logistic regression analysis showed that age elevated( OR 1.346, 95% CI 1.263-1.434, P<0.001), elevated hemoglobin a1c concentration( OR 1.427, 95% CI 1.140-1.785, P=0.002), complicated with hypertension( OR 3.534, 95% CI 1.684-7.418, P=0.001), elevated D-dimer concentration( OR 3.969, 95% CI 1.227-12.841, P=0.021)and elevated uric acid concentration( OR 1.005, 95% CI 1.001-1.008, P=0.006)were independent risk factors for CHD in elderly male patients with T2DM. Conclusion:Elderly patients with T2DM complicated with CHD are more likely to be in hypercoagulable state, more likely to have thromboembolic events, and more obvious renal function damage.Poor fasting blood glucose control and decreased total bilirubin concentration are the influencing factors of CHD in elderly male patients with T2DM.Age elevated, elevated hemoglobin a1c concentration, complicated with hypertension, elevated D-dimer concentration and elevated uric acid concentration are independent risk factors for CHD in elderly male patients with T2DM.
