The blood supply of greater omentum mainly came from the gastroepiploic arch composed of the left gastroepiploic artery and the right gastroepiploic artery.There were 4 main arteries of the greater omentum: ①The right epiploic　artery: The external diameter at origination was (1.0±0.4)mm. ② The middle epiploic artery: The external　diameter at origination was(0.7 + 0.3)mm. ③The left epiploic artery:The external diameter at origination was　(1.2±0.4)mm.④ The accessary epiploic artery:The external diameter at origination was (0.5 ± 0.1)mm.ConclusionAccording to the characteristic of the anterior arch and posterior arch,the position of the middle epiploic artery divarication and the method of spread,the greater omentum is divided into 5 types.It should be according to the characteristic, when the greater omentum is designed and clipped.

Objective To explore the curative effects of unilateral Orthofix external fixation in the treatment of tibial defects.Methods From June 2012 to February 2016,we treated 19 patients with tibial defects using unilateral Orthofix external fixation.They were 14 men and 5 women,aged from 26 to 79 years (mean,43.0 years).The right tibia was involved in 12 cases and the left tibia in 7.The soft tissue defects averaged 6.4 cm × 3.7 cm.The mean bone defect before bone transport was 8.9 cm in length.The anteroposterior and lateral X-ray films of the affected tibia were taken regularly after surgery.Edwards tibial fracture scores were used to evaluate the functional recovery and complications of the affected limb at final follow-ups.Results All the patients were followed up for 10 to 40 months (average,18.5 months).Bone union time ranged from 4 to 16 months (average,9.0 months).Lengths of bone transport ranged from 6 to 10 cm (average,7.8 cm).All the bone defects were reconstructed.According to the Edwards scoring at the final follow-ups,10 cases were rated as excellent,6 as good and 3 as poor.Complications were observed in 4 cases,giving a complication rate of 21.1％.Conclusion Unilateral Orthofix external fixation and bone transport can lead to preferable curative effects in the management of tibial defects.

Objective To evaluate the accuracy of different anatomic landmark methods in determining the size of nasopharyngeal airway.Methods Fifty-two patients of both sexes,aged 16-60 yr,of American Society of Anesthesiologists physical status Ⅰ to Ⅲ,with body mass index of 18-30 kg/m2,scheduled for elective awake craniotomy for supratentorial tumors under sedation-awake-sedation anesthesia,were included.For each patient,the distance from the apex of nose to the right tragus (NT),distance from apex of nose to the right mandibular angle (NM),and thyro-mental distance (TM) were measured and marked on a transnasal tube correspondingly.The patients were placed in supine position without pillow,topical anesthesia (nasal mucosal surface) was performed with 2％ lidocaine,and patients were sedated with midazo1am,propofol and dexmedetomidine.When Observer's Assessment of Alertness/Sedation Scale score was 2 or 3 points,the tube was transnasally inserted to each marked depth.When the three marked depths mentioned above were reached,the positions of the tube's tip were checked using a fiberoptic bronchoscope and recorded as:above epiglottis (the tip of the tube was placed between the epiglottis and the free edge of soft palate) or below epiglottis (the tip of the tube placed at or beyond the epiglottis).Results When the depth reached the NT mark,the tube's tip was above epiglottis in 14 cases (27％),and the tube's tip was below epiglottis in 38 cases (73％).When the depth reached the NM mark,the tube's tip was above epiglottis in 31 cases (60％),and the tube's tip was below epiglottis in 21 cases (40％).When the depth reached the TM mark,the tube's tip was above epiglottis in 52 cases (100％).Compared with the NM and NT methods,the TM method had a higher probability with the tube's tip above epiglottis when used to determine the depth of insertion (P＜0.01).Conclusion TM anatomic landmark method provides higher accuracy in determining the size of nasopharyngeal airway.

Objective:To investigate the risk factors of bone cement leakage and recompression of injured vertebrae after percutaneous kyphoplasty (PKP) for osteoporotic vertebral compression fracture (OVCF).Methods:A case-control study was performed to analyze the clinical data of 297 patients with single-segment OVCF who underwent PKP in First Affiliated Hospital of Soochow University from January 2017 to January 2021, including 67 males and 230 females; aged 60-92 years [(69.5±8.2)years]. According to the occurrence of bone cement leakage, the patients were divided into leakage group ( n=36) and no leakage group ( n=261). According to the occurrence of recompression of injured vertebrae, the patients were divided into recollapse group ( n=40) and no recollapse group ( n=257). The gender, age, fracture segment, type of fracture, fracture severity, cortical disruption, intravertebral cleft, preoperative and postoperative local kyphosis angle, correction value of local kyphosis angle, bone cement injection volume, bone cement distribution, and postoperative anti-osteoporosis treatment were recorded. Univariate analysis was used to analyze the correlation of those factors with bone cement leakage and recompression of injured vertebrae after PKP, followed by multivariate Logistic regression analysis to identify the independent risk factors. Results:Univariate analysis showed that fracture severity, cortical disruption and bone cement injection volume were related to bone cement leakage ( P<0.05 or 0.01). Gender, age, fracture segment, type of fracture, intravertebral cleft, preoperative and postoperative local kyphosis angle, correction value of local kyphosis angle, bone cement distribution, and postoperative anti-osteoporosis treatment were not related to bone cement leakage (all P>0.05). Univariate analysis showed that intravertebral cleft, bone cement distribution, and postoperative anti-osteoporosis treatment were associated with recompression of injured vertebrae (all P<0.01). Gender, age, fracture segment, type of fracture, fracture severity, cortical disruption, preoperative and postoperative local kyphosis angle, correction value of local kyphosis angle, and bone cement injection volume were not related to recompression of injured vertebrae (all P>0.05). Multivariate Logistic regression analysis showed that severe fracture ( OR=4.23, 95% CI 1.52-11.81, P<0.01), cortical disruption ( OR=3.29,95% CI 1.52-7.13, P<0.01), and bone cement injection volume >8 ml ( OR=2.31,95% CI 1.09-4.92, P<0.05) were significantly related to bone cement leakage. Multivariate Logistic regression analysis showed that intravertebral cleft ( OR=2.10, 95% CI 1.03-4.30, P<0.05), solid type of bone cement distribution ( OR=2.56, 95% CI 1.25-5.27, P<0.05) and no anti-osteoporosis treatment after operation ( OR=3.06, 95% CI 1.46-6.40, P<0.01) were significantly related to recompression of injured vertebrae. Conclusions:For OVCF patients, severe fracture, cortical disruption, and bone cement injection volume>8 ml are independent risk factors for bone cement leakage after PKP. Intravertebral cleft, solid type of bone cement distribution, and no anti-osteoporosis treatment after operation are independent risk factors for recompression of injured vertebrae after PKP.

目前，癌症患者的存活率及无病生存率持续提高，但是肿瘤复发率依然较高。肿瘤复发与肿瘤细胞的休眠及耐药有 着密不可分的内在联系。骨髓具有丰富的血管和营养，因此也是原发肿瘤远处转移的主要场所之一。当肿瘤细胞转移到骨髓 内，可以与骨髓内的基质细胞相互作用，并触发肿瘤细胞休眠，休眠状态下的肿瘤细胞不仅可以存活很长的时间，而且对细胞毒 性治疗顽强抵抗；最重要的是在特定的条件下，还可恢复增殖，最终引起肿瘤复发。其中，成骨细胞、间充质干细胞和部分细胞因 子促进肿瘤细胞的休眠，破骨细胞和神经元细胞主要参与肿瘤细胞休眠的停止和转移的发生，而内皮细胞促进肿瘤细胞增殖或 是休眠取决于周围环境的活化状态。本文就上述内容的研究现状做一简要综述。

BACKGROUND: Lung cancer is still the malignant tumor with the highest morbidity and mortality in China. Lung adenocarcinoma is the most common subtype, and the number of lung cancer presenting as mixed ground glass nodule (mGGN) in imaging is gradually increasing. Visceral pleural invasion (VPI) is an important factor affecting the prognosis of mGGN type lung adenocarcinoma. The aim of the study is to explore and analyze the risk factors for VPI in mGGN type lung adenocarcinoma. METHODS: From November 2016 to November 2019, 128 patients with mGGN lung adenocarcinoma underwent radical surgical resection in the First Affiliated Hospital of Nanjing Medical University. Their clinical data, including imaging, pathological and biological features, were collected and analyzed retrospectively. There were 40 males and 88 females, aged 60.3±9.3 years ranging from 30 to 81 years. Single factor Chi-square test and multivariate Logistic regression were used to analyze the risk factors of VPI in mGGN type lung adenocarcinoma. RESULTS: Among 128 mGGN patients who met the inclusion criteria, 57 cases were pathologically confirmed with pleural invasion. Between the VPI (+) and VPI (-) group (P<0.05), there were significant differences in gender, maximum diameter of solid component, consolidation tumor ratio (CTR), spicule sign, history of lung disease, family history of hypertension, relation of lesion to pleura (RLP), coursing relationship between bronchi and nodules. In multivariate Logistic regression analysis, RLP (OR=3.529, 95%CI: 1.430-8.713, P=0.006) and coursing relationship between bronchi and nodules (OR=3.993, 95%CI: 1.517-10.51, P=0.005) were found to be independent risk factors for VPI (P<0.05). CONCLUSIONS The possibility of VPI in m GGN lung adenocarcinoma should be evaluated by combining these parameters in clinical diagnosis and treatment. As independent risk factors, RLP and coursing relationship between bronchi and nodules are instructive to identify VPI in mGGN type lung adenocarcinoma.

OBJECTIVE：To evaluate th e effectiveness ，safety and economy of albu min-bound paclitaxel （nab-PTX）in the treatment of breast cancer by using rapid health technology assessment （HTA），and to provide evidence-based reference for drug selection. METHODS ：Retrieved from PubMed ，the Cochrane Library ，CNKI，Wangfang database and other databases ，systematic evaluation/Meta-analysis，HTA and pharmacoeconomic studies about nab-PTX in the treatment of breast cancer were included ；the conclusions were classified and analyzed by using descriptive analysis. RESULTS ：A total of 5 systematic reviews/Meta-analysis ， 8 pharmacoeconomic studies were included in this study. Compared with conventional taxanes ，nab-PTX increased pathological complete response （pCR）rate [OR ＝1.39，95％CI（1.16，1.67），P＜0.001] and event-free survival （EFS）[HR＝0.69，95％CI（0.57， 0.85），P＜0.001] in neoadjuvant chemotherapy （NAC）-treated breast cancer patients. However ，there were no significant differences in overall survival （OS），progression-free survival （PFS），objective response rate （ORR）and disease control rate （DCR）in metastatic breast cancer （MBC）patients between 2 groups. In the terms of safety ，nab-PTX increased the incidence of grade 3-4 sensory neuropathy [OR ＝1.89，95％CI（1.36，2.61），P＜0.001] in MBC patients ，and increased the incidence of neutropenia [OR ＝ 1.52，95％CI（1.23，1.88，P＜0.001]，sensory neuropathy [OR ＝ 2.17，95％CI（1.38，3.40），P＜0.001]，rash [OR ＝1.46，95％CI mei1213@163.com （1.18，1.80），P＜0.001] and fatigue [OR ＝1.28，95％CI（1.04， 1.56）， P＝0.02] in NAC -treated breast cancer patients.Pharmacoeconomic studies showed that nab-PTX could improve the quality adjusted lif e years of MBC patients compared with traditional taxanes ，and it was a economical option. CONCLUSIONS：Nab-PTX enhances pCR in NAC-treated breast cancer patients ，but has no significant advantage in the effectiveness of MBC patients ，and increases the occurrence of ADR. Nab-PTX may have a cost-utility advantage over conventional taxanes for MBC.
