Relationship between residual collateral vessels in preventive uterine arterial embolization and the risk of bleeding during the operation of curettage for cesarean scar pregnancy / 中华放射学杂志

Objective:To explore the relationship between residual collateral vessels in uterine arterial embolization (UAE) and the risk of bleeding during the operation of curettage for cesarean scar pregnancy.Methods:A total of 499 patients who underwent preventive UAE before curettage for scar pregnancy in Shandong Provincial Hospital from January 2012 to June 2019 were included. Clinical data of the patients were retrospectively collected and analyzed. In patients with uterine collateral circulation, collateral vessels were embolized as much as possible. Angiography was performed after UAE. All the cases were divided into 3 grades according to residual staining in middle and lower part of corpus uteri as follows, grade A: no or mild staining, grade B: moderate staining, grade C: intense staining. Blood loss of the patients during curettage was recorded, and the incidence rate of minor hemorrhage (<50 ml) and massive hemorrhage (>500 ml) of the 3 grades were calculated respectively. The results of three grades groups were compared with those of control group (patients without collateral circulation) by using Chi-square test or Fischer exact probability.Results:According to angiogram acquired after UAE, collateral vessels were found in 53 patients, with 25 cases in grade A group, 15 cases in grade B group, and 13 cases in grade C group, respectively. Thirty-six patients underwent transcatheter embolization of collateral vessels. The incidence rate of minor hemorrhage in type B and C [60.0% (9/15), 46.2% (6/13)] was lower than that in control group (87.9%, 392/446), with significant difference found (χ2=9.972, P=0.002, χ2=19.090, P<0.001). Significant difference was found in the incidence rate of massive haemorrhage between group C (23.1%, 3/13) and control group (2.2%, 9/446) (χ2=14.480, P=0.001). Conclusion:As for cesarean scar pregnancy cases with uterine collateral vessels, embolization of collateral vessels may reduce the amounts of bleeding during curettage. Residual staining of middle and lower part of corpus uteri may be helpful in predicting the risk of massive haemorrhage during curettage.

Diagnosis of peripheral pulmonary lesions using endorbronchial ultrasonography with a guide sheath combination with virtual bronchoscopic navigation / 中国内镜杂志

Objective To assess the diagnosis value of endorbronchial ultrasonography with a guide sheath combination with virtual bronchoscopic navigation at peripheral lung lesions. Methods 23 patients with lung peripheral lesions, 10 cases male, 13 cases female, age 29~78, the median age of 61, were retrospectively analyzed by diagnosised with EBUS-GS-TBLB combination VBN from March 2015 to December 2015. Results 23 cases of patients, 8 cases of adenocarcinoma, squamous carcinoma in 5 cases, mixed carcinoma in 1 case, 1 case of small cell carcinoma and lung metastatic carcinoma in 1 case, 2 cases were tuberculosis, 1 case of inflammation, 4 cases were negative. The total positive rate was 82.6%. Conclusion EBUS-GS-TBLB combination with VBN to the diagnosis of lung lesions with high positive rate, it is worthy of promoting clinically.

Emergency embolization in the treatment of intractable epistaxis resulted from carotid arterial disease / 中华放射学杂志

Objective To evaluate the clinical value of internal carotid artery occlusion in treatment of intractable epistaxis caused by carotid artery siphon traumatic lesions.Methods A total of 37 patients with intractable epistaxis caused by traumatic carotid artery siphon pseudoaneurysm or carotid cavernous fistula were retrospectively analyzed.All the patients underwent embolization from October 1998 to June 2010,including 34 men and 3 women with the age ranged from 25 to 65 years and a average of 40 years.Only lesions were occlued in 12 cases without involving the internal carotid artery,while occlusions of internal carotid artery were performed in the rest 25 cases.Results Thirty-six patients were cured without recurrent hemorrhage after embolization.Only 1 patient with carotid artery occlusion died 48 hours after operation.Conclusion For patients with carotid arterial intractable epistaxis,if the elimanation of the lesions is not applicable and the collateral circulation of Willis ring has a good compensation,the use of detachable balloon or coil occlusion of ipsilateral internal carotid artery is a quick and easy method to save patients' lives.

Concept and significance of a subjective and multiple index system of clinical evaluation for traditional Chinese medicine / 中西医结合学报

Traditional Chinese medicine (TCM) has its own system of diagnosis and treatment theory, and its methods for evaluating clinical efficacy are different from those of Western medicine. Applying evaluation techniques and methods that are used in Western medicine mechanically to TCM will not work. So building evaluation techniques, which adhere to regulations and characteristics of TCM, is necessary and imperative. As the quality of life and patient-reported outcome instruments were brought into practice and developed, clinical evaluation ideas and methods for TCM are provided with an opportunity for development. This article puts forward the concept of subjective complex outcomes (SCOs), which constitutes subjective feelings gained from the patient, doctor and caregiver, different from laboratory parameters. SCOs provide a multidimensional and complex health-related quality of life (HRQL) assessment and focus on the source of assessment information of diseases. This article also introduces a case study building SCO methods of TCM treatment for chronic obstructive pulmonary diseases, in order to promote discussion and provide a platform for future research.

The Plasma Levels of PAl-1, TGF-β and TNF-αin Pleural Effusion before and after Intrapleural Injection of Kanglaite Combined with Cisplatin / 天津医药

Objective: To detect the levels of plasminogen activator inhibitor-I (PAI-1), transforming growth factor-β (TGF-β)and tumor necrosis factor-α (TNF-α) in the pleural fluid before and after intrapleural injection of Kanglaite combined with Cisplatin, and the mechanisms thereof. Methods: Patients were randomly divided into three groups, the Kanglaite combined with Cisplatin group (combination treatment group), Kangkaite group and Cisplatin group. The levels of PAl-1, TGF-β and TNF-α were determined by ELISA in pleural effusion 24 h and 48 h before and after intrapleural injection of medicine. Results: The levels of PAI-1, TGF-βand TNF-αawere higher 24 h and 48 h after treatment compared with those of pre-treatment in three groups (P＜0.05). There were no statistical significances in levels of PAI-1 and TGF-β24 h after injection medicine in three groups. But the level of TNF-α was higher in the combination treatment group than that in Kangkaite and Cisplatin groups(P＜0.05). After injection medicine 48 h, the levels of PAl-I, GF-β and TNF-α were higher in the combination treatment group than those in Kangkaite group (P＜0.05). Conclusion: The treatment of Kanglaite combined with Cisplatin activates PAI-1, TGF-β and TNF-αcytokines and causes inflammatory, suppresses fibrinolytic activity. These cytokines promote fibrin and induce pleural adhesion.

Transcatheter embolization for high blood flow vascular malformations of oral maxillofacial region / 介入放射学杂志

Objective To explore the treatment and efficiency of high blood flow vascular malformations of oral maxillofacial region with super-selective arterial embolization. Methods 18 cases underwent angiography of the head and neck before treatment and then followed by super-selective catheterization with microcatheter to embolize the feeding vessels of the vascular malformations with PVA. 8 cases underwent surgical excision within 72 hours after the embolization and the other 10 cases passed through the arterial radical emboliztion treatment. Results Technical success ratio reached 100% with no complications causing skin necrosis or incorrect arterial embolization else where in the skull. All 8 cases undergone preoperative embolization showed obviously less bleeding, easier removal of the mass and reduction of operation time. 10 cases with radical arterial embolization manifested reduction of swelling and improvement of organ function within 1 to 24 months after the procedure. 5 patients were cured with only once operation, 4 cases with twice operation and 1 with the thrice. Conclusions Aterial embolization is a safe and effective method in the treatment of high blood flow vascular malformations of oral maxillofacial region.
