Objective:To investigate the effects of one-lung ventilation with a laryngeal mask airway combined with a bronchial blocker on respiratory function in older adult patients undergoing thoracoscopic surgery.Methods:Sixty older adult patients who underwent thoracoscopic surgery in Zhejiang Veteran Hospital from January 2019 to December 2020 were included in this study. They were randomly divided into a single group (a simple bronchial blocker) and a combined group (a bronchial blocker combined with a laryngeal mask airway), with 30 patients in each group. Awakening (time to extubation, spontaneous respiration and eye opening), respiratory function [peripheral oxygen saturation, vital capacity, maximum voluntary ventilation measured before and 3 days after surgery], hemodynamics [heart rate and mean arterial pressure were recorded before (T 1) and immediately after placement of a bronchial blocker or a laryngeal mask (T 2) and at the time of removal of a bronchial block or a laryngeal mask (T 3)], and adverse events (hoarseness, throat pain, dysphagia and choking) were recorded. Results:Time to extubation, time to spontaneous respiration, and time to eye opening in the combined group were (5.62 ± 1.23) minutes, (6.85 ± 1.34) minutes, and (7.34 ± 1.52) minutes, respectively, which were significantly shorter than (8.62 ± 1.55) minutes, (10.25 ± 1.78) minutes, (11.38 ± 1.85) minutes in the single group ( t = 9.94, 10.00, 11.06, all P < 0.05). At 3 days after surgery, peripheral oxygen saturation, vital capacity, and maximum voluntary ventilation in the combined group were (98.23 ± 1.05)%, (2.18 ± 0.60) L, (54.23 ± 5.36) L, respectively, which were significantly higher than (96.23 ± 1.01)%, (1.82 ± 0.50) L, (48.12 ± 4.23) L in the single group ( t = 7.51, 2.52, 4.90, all P < 0.05). Mean arterial pressure measured at T 3 was significantly lower in the combined group than that in the single group [(98.25 ± 2.32) mmHg vs. (93.35 ± 2.48) mmHg, t = 7.90, P < 0.05]. The incidences of hoarseness, throat pain and choking in the combined group were 6.66% (2/30), 10.00% (3/30), 6.66% (2/30), respectively , which were significantly lower than 33.33% (10/30), 43.33% (13/30), 43.33% (13/30) in the single group (χ 2 = 6.66, 8.52, 10.75, all P < 0.05). There was no significant difference in the incidence of dysphagia between the two groups ( P > 0.05). Conclusion:Use of a laryngeal mask airway combined with a bronchial blocker during thoracoscopic surgery in older adult patients facilitates postoperative recovery, has little impact on hemodynamics, and is highly safe.

Objective To explore the clinical features and causes of misdiagnosis of the patients with acquired deficiency of vitamin K-dependent coagulation factors (ADVKDCF). Methods Retrospective analysis was performed with the data from 62 patients with ADVKDCF for etiological factors, clinical manifestations,laboratory examinations, diagnosis and treatments. Results Among the 62 patients, 51 patients were with unknown causes( subgroup A) and 11 were with clear histories of anticoagulant rodenticide poisoning( subgroup B). The presentations of hemorrhage of the patients varied with hematuria as the most common first symptom,followed by skin, mucosa, muscle, internal organs bleeding (28/62). The most common hemorrhage symptom is hematuria. 35 of the 62 patients had hemoglobin(Hb) levels less than 100 g/L due to blood loss( the lowest level was 32 g/L). Thirty-eight patients were misdiagnosed at the first visit and the median time from hemorrhage manifestation to definite diagnosis was 8 days (range,2 to 192 days). ADVKDCF was mostly misdiagnosed as the urinary system diseases (23/38), followed by hemophilia (8/38). Laboratory examinations showed normal platelet count , throm bin time (TT) and normal fibrinogen(Fg) concentration, but prolonged plasma prothrombin time (PT), activated partial prothrombin time (APTT) and international normalized ration (INR). All of patients received high dose vitamin K ( intravenous vitamin K1 with a initial dose of 20 to 240 mg/d and then oral vitamin K4 maintenance) . The bleeding symptoms disappeared 1 day after treatment and the Hb levels increased dramatically. There were significant differences in PT, APTT and INR of the patients before and after treatment( P <0. 01 ). Followed by a median follow - up of 8 months , no patient had severe adverse effects or recurrence. Conclusion The hemorrhage presentations of the patients with ADVKDCF are various. The most common hemorrhage symptom is hematuria. The misdiagnosis rate of ADVKDCF is high with urinary systems disorders as the most common misdiagnosis. Sequential treatment with vitamin K is an effective and safe method to prevent recurrence. Early detection of coagulation function is helpful to reduce misdiagnosis possibility.

Objective To investigate the clinical pathological characteristics, diagnosis and treatment of breast rhabdomyosarcoma, and to enhance the awareness of malignancy infiltration to bone marrow (BM). Methods The data of one case of Rhabdomyosarcoma of breast were analyzed retrospectively. BM aspirate and biopsy, morphology, immunology, cytogenetics, molecular biology (MICM) in different parts of BM, peripheral blood smear, fine puncture of breast mass, final biopsy of breast mass by Mammotome System and whole body PET-CT were performed. The immunochemistry stain of specimen of breast mass was used. Results The peripheral blood smear of this patient showed immature erythrocytes, leucocytes and classification of unknown cells which were consistent with BM morphology. The results of BM aspirate and biopsy depicted a hypercellular specimen with disseminated unknown cells infiltration. Unknown cells were positive for CD56 and negative for any hematopoietic markers by flow cytometry. The whole body PET-CT showed that uptake of 18F-FDG of bilateral breast and whole BM was increased, whereas the mass of breast was not presented by CT. PET-CT suggested a probable malignant hematologic disease. The enough specimen of breast mass got from Mammotome System showed embryonal rhabdomyosarcoma, and the tumor cells were positive for MyoD1, Vimentin and Desmin. Conclusions It is a challenge for early diagnosis of solid sarcoma with unknown origin which diffusely infiltrating into BM. Negative expression of hematopoietic markers by flow cytometry plays a role on differential diagnosis in this setting, whereas PET-CT only provides a valuable reference. Enough specimen and immunohistochemical staining could provide solid evidences of diagnosis.

Objective:To analyze the correlation between phonographic cardiac function and uterine artery resistance index (RI) in pregnant women with hypertension of different conditions during pregnancy by color Doppler ultrasonically.Methods:A total of 100 pregnant women with gestational hypertension admitted to Lishui People′s Hospital from January 2020 to February 2021 were selected and divided into gestational hypertension group (40 cases), mild pre-eclampsia group (30 cases) and severe pre-eclampsia group (30 cases) according to the severity of their disease. Another 30 normal pregnant women who underwent physical examination during the same period were selected as the control group. The left ventricular function parameters isovolumetric relaxation time (IVRT), left ventricular ejection fraction (LVEF), left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume(LVESV), left atrial volume index (LAVI) and uterine arter RI in 4 groups were quantitatively analyzed by ultrasound during 28 to 38 weeks of gestation. The correlation between cardiac ultrasound parameters and of pregnant women RI were analyzed.Results:As the severity of the disease, the levels of IVRT, LVEDV, LVESV, LAVI were gradually rised, and the level of LVEF was gradually decreased, there were significant differences among the 4 groups ( P<0.05). The uterine arter RI in the control group, gestational hypertension group, mild pre-eclampsia group and severe pre-eclampsia group was 0.42 ± 0.04, 0.50 ± 0.05, 0.54 ± 0.11, 0.58 ± 0.06, there was significant difference ( F = 34.11, P<0.001), and as the severity of the disease , the level of uterine arter RI was gradually rised, there were significant differences among the 4 groups ( P<0.05). Pearson correlation analysis showed that IVRT had certain correlation with RI in the 4 groups ( r = 0.331, 0.450, 0.531, 0.582; P<0.05). In mild and severe pre-eclampsia group, there were a certain correlation between LVEDV, LVESV and RI (in mild pre-eclampsia group: r = 0.360 and 0.411, P<0.05; in severe pre-eclampsia group: r = 0.383 and 0.451, P<0.05). Conclusions:The left heart function of pregnant women with different conditions evaluated by ultrasound showed a downward trend, and the uterine artery RI increased gradually in pregnant women with severe pre-eclampsia, and RI was closely related to the cardiac ultrasound parameter IVRT.
