Objective To determine the clinical implications of internal mammary node biopsy for neoplasm stage,treatment,and prognosis in patients with breast cancer.Methods Internal mammary node biopsy via intercostal space was performed in 229 cases of breast cancer.Anatomical location of internal mammary nodes was recorded.Results Internal mammary node biopsy was successfully finished in 220 patients.There were 56 cases (24.45％ ) with internal mammary nodes metastasis,126 cases (55.02％ ) with axillary nodes metastasis,43 cases (34.13％ ) with regional metastases in both the axillary and internal mammary lymph nodes and 13 cases ( 12.62％ ) with internal mammary node metastasis only.Internal mammary node metastasis rate in patients with the number of positive axillary nodes ≥4 was 49.32％ (36/73).pN stage migration was seen in 56 patients with positive internal mammary nodes.There was no statistic relation between internal mammary nodes metastases and tumor location ( x2 =0.661,P =0.719).70.7％ patients with medial/central tumors and 50.7％ patients with the number of positive axillary nodes ≥4 were free from internal mammary node radiotherapy on account of internal mammary node biopsy.There was no complication such as pneumothorax or haemorrhagia.Conclusions Internal mammary node biopsy from intercostal space is a reliable surgical technique and can improve pN stage in some breast cancer patients.With internal mammary node biopsy,patients with a negative internal mammary node can be prevented from radiation to internal mammary nodal areas.

Objective To explore the best operation method in the patients with papillary thyroid microcarcinoma.Methods A total of 139 patients with papillary thjroid microcarcinoma were treated at our institute between Jan.2000 and Jan.2010.The data on the clinicopathological characteristics of patients and treatment were collected.Results The mean tumor size was (0.45 ± 0.24) cm.Of the 139 patients,30.2％ had multifocal tumors,19.4％ had bilateral tumors,42.4％ neck lymph node metastases.The number of eases of lymph node metastasis in level Ⅵ,Ⅱa,Ⅲ and Ⅳ was 58(41.7％),3(2.2％),10(7.9％),5(3.6％),respectively.Only one had lymph node metastasis in Level Ⅲ Microscopic extrathyroid extension was associated with neck lymph node metastases in papillary thyroid microcareinoma patients (x2 =38.39,P ＜0.001).No one developed permanent hypoparathyroidism.The median follow-up time was 103 (range,30-154) months,and local recurrence in the thyoid was diagnosed in 2 patients who underwent hemi-or subtotal thyroidectomy.Follow-up of 10 years was done in 16 cases,and the survival rate of 139 patients for 10-year was 100％.Conclusions It suggested that patients with papillary thyroid microcarcinoma has uniform clinicopathologic characteristics and the pattern of lymph node metastasis from those with papillary thyroid carcinoma.Total thyroidectomy plus level Ⅵ dissection is the optimal surgical treatment of papillary thyroid microcarcinoma.

Objective:To investigate the expression of transmembrane 4 super family 1 (TM4SF1)in breast cancer tissue,and to elucidate its clinical significance and explore the related molecular biological mechanisms. Methods:A total of 190 cases of human breast cancer,110 cases of paracancerous tissue and 110 cases of normal breast tissue were collected.Immunohistochemistry was used to detect the expression levels of TM4SF1 mRNA in breast cancer tissue,paracancerous tissue,and normal breast tissue;Western blotting method was used to detect the expression levels of TM4SF1 in breast cancer tissue,paracancerous tissue,and normal breast tissue;RT-PCR method was used to detect the expression levels of TM4SF1 mRNA in breast cancer tissue,paracancerous tissue, and normal breast tissue.The positive expression rates of TM4SF1 in breast cancer tissue of the breast cancer patients with different clinicopathological features were detected.Results:The positive expression rate of TM4SF1 in the breast cancer tissue was significantly higher than those in paracancerous tissue and normal breast tissue (P <0.05);there was no significant difference in the positive expression rates of TM4SF1 between paracancerous tissue and normal breast tissue (P = 0.531);the expression of TM4SF1 was not correlated with age,but was closely correlated with tumor size,differentiation degree,lymph node metastasis and tumor stage (P <0.05);the positive expression rate of TM4SF1 in basal like breast cancer tissue was higher than those in the other three types of tissues (P <0.05).The results of Western blotting showed that the expression level of TM4SF1 in breast cancer tissue was higher than those in paracancerous tissue and normal breast tissue (P < 0.05 ), but there was no significant difference in the expression level of TM4SF1 between paracancerous tissue and normal breast tissue (P >0.05). The results of RT-PCR showed that the expression level of TM4SF1 mRNA in breast cancer tissue was higher than those in the paracancerous tissue and normal breast tissue (P <0.01);there was no significant difference in the expression level of TM4SF1 mRNA between paracancerous tissue and normal breast tissue (P > 0.05 ). Conclusion:The TM4SF1 is highly expressed in breast cancer tissue. TM4SF1 may affect the occurrence, development and distant metastasis of breast cancer through various mechanisms.TM4SF1 may be a potential target for the treatment of breast cancer.

Objective:To investigate the risk factors for preoperative hypoxemia in geriatric patients with hip fracture.Methods:A case-control study was used to analyze the clinical data of 99 geriatric patients with hip fracture admitted to Zhongda Hospital affiliated to Southeast University between November 2020 and August 2021. There were 29 males and 70 females, aged 67-96 years [(82.6±6.2)years]. The patients were divided into hypoxemia group ( n=51) and non-hypoxemia group ( n=48) using partial arterial partial pressure of oxygen (PaO 2)<80 mmHg while breathing room air at emergency as the reference standard. The two groups were compared in terms of sex, age, fracture types, body mass index (BMI), American Society of Anesthesiologists (ASA) classification, pulmonary diseases diagnosed by preoperative chest CT [atelectasis, pleural effusion, chronic obstructive pulmonary disease (COPD)], time from injury to visit, New York Heart Association (NYHA) classification, Barthel index, KATZ index, modified Medicine Research Council (mMRC) dyspnea scale, numeric rating scale (NRS), smoking, drinking, comorbidities (hypertension, diabetes mellitus, Parkinson′s disease, Alzheimer′s disease, cerebral infarction, coronary atherosclerotic heart disease), body temperature, blood routine test at first examination (erythrocyte count, leukocyte count, C-reactive protein, hemoglobin), biochemistry (serum albumin, blood glucose, blood creatinine, blood urea nitrogen), electrolyte (serum potassium, serum sodium), and other related examinations [D-dimer, brain natriuretic peptide (BNP), lactic acid]. Univariate analysis was performed to the correlation of those indicators with preoperative hypoxemia. Multivariate Logistic regression analysis was used to identify the independent risk factors for preoperative hypoxemia in geriatric patients with hip fracture. Results:Differences in sex, age, fracture types, BMI, pulmonary diseases diagnosed by preoperative chest CT, time from injury to visit, Barthel index, KATZ index, NRS, smoking, drinking, comorbidities, body temperature, first laboratory results of erythrocyte count, biochemistry, electrolyte and other related examinations were not statistically significant between the two groups (all P>0.05). The two groups showed statistical differences in ASA classification, NYHA classification, mMRC dyspnea scale, leukocyte count at first examination, C-reaction protein and hemoglobin (all P<0.05). Univariate analysis indicated that ASA classification, NYHA classification, mMRC dyspnea scale, leukocyte count at first examination and C-reaction protein were correlated with the occurrence of preoperative hypoxemia in geriatric patients with hip fracture (all P<0.05). Multivariate Logistic regressions analysis indicated that higher mMRC dyspnea scale ( OR=2.30, 95% CI 1.10-4.81, P<0.05), higher leukocyte count at first examination ( OR=1.24, 95% CI 1.05-1.45, P<0.05), higher level of C-reaction protein ( OR=1.02, 95% CI 1.01-1.03, P<0.05) and higher level of hemoglobin ( OR=1.04, 95% CI 1.01-1.07, P<0.05) were significantly correlated with the occurrence of preoperative hypoxemia in geriatric patients with hip fracture. Conclusion:Higher mMRC dyspnea scale, higher leukocyte count, higher level of C-reaction protein and higher level of hemoglobin are independent risk factors for preoperative hypoxemia in geriatric patients with hip fracture.

Objective:To evaluate the radiological and clinical outcomes of the aged patients with unstable proximal humeral fracture (UPHF) treated with a locking plate and an intramedullary titanium mesh.Methods:A retrospective study was conducted to analyze the 43 aged patients with UPHF who had been admitted to Department of Orthopedics, Zhongda Hospital Affiliated to Southeast University from January 2017 to July 2019. There were 13 males and 30 females with an age of (71.3±10.3) years (from 60 to 83 years). All patients were treated with a locking plate and an intramedullary titanium mesh to support. The postoperative imaging measurements included changes in humeral head height (HHH) and neck-shaft angle (NSA) (the difference between 3 years after surgery and the second day after surgery, taken as an absolute value); the postoperative clinical measurements included visual analogue scale (VAS), range of shoulder motion, Constant-Murley shoulder functional score (Constant score), American Shoulder and Elbow Surgeons (ASES) score, and incidence of complications.Results:All patients were followed up for (39.2±2.3) months after surgery. The change in HHH at 3 years after surgery was (1.5±1.1) mm, and the change in NSA at 3 years after surgery 3.3°±2.6°. At 3 years after surgery, the VAS score was (2.2±1.3) points, the Constant score (79.2±9.1) points, and the ASES score (78.9±9.2) points; the range of forward extension was 143.2°±20.8°, the range of outward extension 139.3°±23.1°, and the range of outward rotation 55.1°±4.7°. Complications after surgery were found in 6 patients, including humeral head necrosis in 2 cases, ectopic ossification in 1 case, and infection in 3 cases.Conclusion:In the treatment of the aged patients with UPHF, a locking plate combined with an intramedullary titanium mesh can help to restore the medial column support, leading to fine radiological and clinical outcomes.
