Papillary thyroid carcinoma (PTC) is prone to lymph node metastasis in the central region of neck. However, the necessity of prophylactic central neck lymph node dissection (pCND) is still controversial. This paper reviews the construction of multi-dimensional risk stratification based on the actual situation of patients, and formulates different pCND plans after accurate assessment, to improve the quality of life of patients and to reduce complications and recurrence rate.

Objective To investigate the distribution,risk factors and prognosis of VA-ECMO patients with capillary leakage syndrome(CLS).Methods 115 cases of VA-ECMO were collected in Emergency department,ICU 1 and 2 of Ruikang Hospital Affiliated to Guangxi University of Chinese Medicine from December 2019 to December 2023 for prospective clinical observation study.It was observed the operation time and status of VA-ECMO and whether VA-ECMO patients were complicated with CLS.At the same time,type of disease,blood gas pH,HCO3-concentration,lactate value(LAC),serum albumin and so on were recorded.The influence of various factors on VA-ECMO with CLS was analyzed by binary Logistic regression.T test was used for measurement data and χ2 test was used for counting data.Results Capillary leakage syndrome in VA-ECMO patients were 61 cases,which had accounted for 53.04%.Sepsis,ECPR,pH value and LAC were the risk factors for VA-ECMO with CLS(P<0.05).The operation failure rate of ECMO in 24 hours of CLS group was 49.18%higher than that of non-CLS group(P<0.001).The mean running time of ECMO in CLS group was 39.53 hours,which was lower than that of non-CLS group(t=2.318,P<0.05).The mortality rate of CLS group was 88.24%,higher than that of non-CLS group(57.69%)(χ2=14.18,P<0.001).Conclusions The proportion of VA-ECMO combined with CLS was not low.Sepsis,ECPR,pH value and LAC were risk factors for VA-ECMO with CLS,and VA-ECMO combined with CLS seriously affected the operation of ECMO.For patients with VA-ECMO,it should be paid more attention to observe whether they have capillary leakage and its risk factors,and the potential etiology should be treated early to promote the progress of ECMO and improve their prognosis.

Objective:To compare the clinical efficacy of a fixed exoskeleton robot with that of an exoskeleton walker in training the balance of stroke survivors in the subacute stage.Methods:Thirty persons with subacute stroke were divided at random into a fixed robot group (15 cases) and a walking robot group (15 cases). In addition to conventional rehabilitation treatment, the fixed robot group underwent daily 20-minute treadmill-based fixed exoskeleton robot training, 5 days a week for 2 weeks. The walking group was trained with an exoskeleton walking robot on the same schedule. Before and after the treatment, the Berg balance scale, the sitting modified functional stretch test (SMFRT), an isokinetic muscle strength test and the modified Barthel index (MBI) were used to evaluate the subjects′ global balance, self-dynamic balance, knee proprioception and ability in the activities of daily living (ADL).Results:After the treatment, both groups′ average Berg score, SMFRT extension difference, proprioceptive absolute error angle in the affected knee and MBI had improved significantly. The average SMFRT extension difference after treatment in the walker group was then significantly better than the fixed robot group′s average. However, the fixed robot group′s proprioception in the affected knee joint was then significantly better, on average, than among the walking robot group.Conclusions:Both fixed exoskeleton robot training and exoskeleton walker training can improve the balance, proprioception and ADL ability after a stroke. The former better improves dynamic balance; the latter better improves proprioception in the affected knee joint.

Objective:To estimate the costs of dementia from a societal perspective in Tongliao City and ex-plore the influencing factors of these costs.Methods:Dementia was diagnosed using the 10/66 Dementia Research Group assessment instruments.Data on healthcare utilization,caregiver's care time or costs,and the distress due to caregiving were collected.The cost-proportion conversion method was used to estimate the per capita cost of health services based on data from the National Statistical Yearbook.The human capital approach was used to estimate the unit value of informal care time,and the willingness-to-pay method was used to measure the intangible costs of car-egivers.The total societal costs of dementia were calculated based on the reference year 2023,and a two-part model was employed to analyze the factors influencing the societal costs.Results:A total of 390 dementia patients were di-agnosed,with an average societal cost per capita of 117 877 Yuan.The largest cost component was informal care provided by unpaid family members,accounting for 73.1％of the total societal cost.The societal costs for female patients were 61 395 Yuan higher than those for male patients.Patients with comorbid stroke had a higher societal cost of 63 008 Yuan compared to patients without stroke,and each additional chronic disease added 5 868 Yuan to societal costs.Additionally,each non-memory dimension impairment in the Clinical Dementia Rating Scale in-creased the societal costs by 53 997 Yuan.Conclusion:Dementia poses a significant socio-economic burden,with informal care being the major component of this burden.

Objective:To evaluate direct and indirect costs for schizophrenia,major depressive disorder(MDD)and bipolar disorder,and to compare their differences of cost composition,and to explore the drivers of the total costs.Methods:A total of 3 175 inpatients with schizophrenia,MDD,and bipolar disorder were recruited.In-patient's self-report total direct of medical costs outpatient and inpatient,out-of-pocket costs,and direct non-medical costs were regarded as direct costs.Productivity loss and other loss caused by damaging properties were defined as indirect costs.The perspectives of this study included individual and societal levels.Multivariate regression analysis was applied for detecting the factors influencing disease costs.Results:The total cost of schizophrenia was higher than those of MDD and bipolar disorder at individual and societal levels.The indirect costs of three mental disorders were higher than the direct costs,and the indirect cost ratio of bipolar disorder was higher than those of schizophre-nia and MDD.Age,gender,working condition and marital status(P＜0.05)were the important drivers of total costs.Conclusion:The economic burden of the three mental disorders is relatively heavy.Schizophrenia has heaviest disease burden,and the productivity loss due to mental disorders is the driving force of the soaring disease cost

Objective:To explore the clinicopathological features and prognosis of renal mucinous tubular spindle cell carcinoma (MTSCC).Methods:The clinical data of 16 patients with MTSCC admitted to the First Affiliated Hospital of Zhengzhou University from July 2013 to July 2022 were retrospectively analyzed. There were six male cases and ten female cases. The mean age was (56.4±11.4) years old. Among them, 10 cases were asymptomatic, two complained of hematuria, three complained of lumbar pain, and one complained of lower limb pain. Twelve cases underwent preoperative enhanced CT examination, 6 cases of ultrasound examination, 3 cases of MRI examination, and 1 case of bone scan. Imaging manifestations showed that the masses were round or round-like with clear borders. Two cases combined with hemorrhage and three cases combined with calcification. Five cases showed exophytic growth, 10 cases partially exophytic, and 1 case completely endophytic. The maximum diameter of the tumor was (65.7±27.4) mm. The tumors were located in the left kidney in 11 cases and in the right kidney in 5 cases. The tumors were mildly delayed-enhancing under enhanced CT, long/short T1 signal mixed with long/short T2 signal under MRI, and diffusion-limited high signal under DWI. The tumors were hypoechoic masses without obvious blood flow signals under ultrasound. Twelve cases were diagnosed as renal occupying neoplasms, 2 cases were suggested as lack of blood supply renal tumor, and one was considered renal tumor rupture and bleeding. In one case, a bone scan suggested metastasis to the thoracic spine and pelvis. The metastatic renal tumor was diagnosed, and a renal puncture was performed to clarify the pathology. Eleven patients underwent laparoscopic radical nephrectomy, and 4 patients underwent partial nephrectomy. One case was metastasized without surgery and treated with apatinib mesylate and zoledronic acid.Results:The postoperative pathological specimens showed grayish, grayish-yellow, or grayish-red masses with a soft or medium texture. No perinephric, ureteral, or adrenal invasion was seen in all tumors. Microscopically, the tumor cells were round and ovoid. The tumor cells were arranged in tubular and striated shapes, and mucus pools were locally visible. No sarcomatous component was seen in all tumors. There were 9 patients with pT 1N 0M 0, 6 patients with pT 2N 0M 0, and 1 patient with pT 1N 0M 1. After operation, 2 patients with pT 2N 0M 0, who underwent laparoscopic radical nephrectomy were treated with pazopanib and sunitinib, respectively. All patients were followed up for a median of 50.7(25.8, 75.0)months, 15 patients were free of recurrent metastases, and 1 patient with pre-puncture metastasis died due to tumor progression of multiple pulmonary and bone metastases, with a survival of 16.9 months. Conclusions:Renal MTSCC is rare, mostly found on physical examination, with female patients predominantly, and imaging shows a lack of blood supply tumor. Surgery is the primary treatment method. Partial nephrectomy or radical nephrectomy could be chosen according to the tumor stage, kidney function, and patient's underlying condition, and patients have a good prognosis.

Objective:To investigate the application value of P-loop digestive tract recons-truction in pancreaticoduodenectomy (PD).Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 21 ampullary disease patients undergoing PD in the Liuzhou People′s Hospital Affiliated to Guangxi Medical University from April to December 2020 were collected. There were 13 males and 8 females, aged from 35 to 76 years, with a median age of 60 years. All the 21 patients underwent PD and digestive tract reconstruction using P-loop method based on the Child reconstruction. Observation indicators: (1) surgical situations; (2) postoperative situations; (3) follow-up. Follow-up was conducted using outpatient examination or telephone interview to detect survival and discomfort symptoms of patients up to December 2020. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers or persentages. Results:(1) Surgical situations: all the 21 patients underwent PD successfully. The operation time, time of P-loop anastomosis and volume of intraoperative blood loss of 21 patients were (317±74)minutes, (14±3)minutes and 375 mL(range, 100-800 mL), respectively. Of the 21 patients, 17 cases had pancreatic texture as soft, 4 cases had pancreatic texture as hard, 3 cases had diameter of pancreas ≤3 mm, 18 cases had diameter of pancreas >3 mm, 14 cases were placed pancreatic duct stent, 7 cases were not placed pancreatic duct stent. (2) Postoperative situations: 2 of the 21 patients had grade A pancreatic fistula, and none of patient had grade B or grade C pancreatic fistula. One case had hepaticojejunal anastomotic fistula, 2 cases without pancreatic fistula had delayed gastric emptying and none of patient had abdominal infection or bleeding. The duration of postoperative hospital stay of 21 patients was (16±5)days, and none of patient died during postoperative 30 days. Results of postoperative histopathological examination showed there were 10 cases with duodenal papillary carcinoma, 4 cases with lower bile duct carcinoma, 3 cases with pancreatic head ductal adenocarcinoma, 1 case with duodenum stromal tumors, 1 case with gastric antrum carcinoma, 1 case with mass in the head of the pancreas of IgG4 and 1 case with choledochal cyst of type 3. (3) Follow-up: all 21 patients were followed up for 1.0 to 7.0 months, with a median follow-up time of 4.3 months. None of patient died. There was no abdominal pain, distension or dyspepsia during follow-up. One case was diagnosed as tumor liver metastasis at postoperative 5 months.Conclusion:P-loop digestive tract reconstruction in PD is safe and effective, with good short-term effect.
