Objective: To examine the short-term curative effect with minimally invasive right infra-axillary thoracotomy for transaortic modified Morrow procedure. Methods: The clinical data of 60 patients who underwent video-assisted thoracoscopic transaortic modified Morrow procedure from August 2021 to August 2022 at Department of Cardiovascular Surgery, Zhejiang Provincial People's Hospital were retrospectively analyzed. There were 31 males and 29 females, with the age (M (IQR)) of 54.0(22.3) years (range: 15 to 71 years). The echocardiography confirmed the diagnosis of moderate mitral regurgitation in 30 patients, and severe mitral regurgitation in 13 patients. Systolic anterior motion (SAM) was present preoperatively in 54 patients. All 60 patients underwent transaortic modified Morrow procedure through a right infra-axillary thoracotomy using femorofemoral cardiopulmonary bypass. Surgical procedures mainly included transverse aortic incision, exposure of left ventricular outflow tract (LVOT), septal myectomy, and correction of the abnormal mitral valve and subvalvular structures. Results: All 60 patients underwent the programmatic procedures successfully without conversion to full sternotomy. The cardiopulmonary bypass time was (142.0±32.1) minutes (range: 89 to 240 minutes), while the cross-clamp time was (95.0±23.5) minutes (range: 50 to 162 minutes). The patients had a postoperative peak LVOT gradient of 7.0 (5.0) mmHg (range: 0 to 38 mmHg) (1 mmHg=0.133 kPa). A total of 57 patients were extubated on the operating table. The drainage volume in the first 24 h was (175.9±57.0) ml (range: 60 to 327 ml). The length of intensive care unit stay was 21.0 (5.8)h (range: 8 to 120 h) and postoperative hospital stay was 8 (5) days (range: 5 to 19 days). The postoperative septal thickness was 11 (2) mm (range: 8 to 14 mm). All patients had no iatrogenic ventricular septal perforation or postoperative residual SAM. The patients were followed up for 4 (9) months (range: 1 to 15 months), and none of them needed cardiac surgery again due to valve dysfunction or increased peak LVOT gradient during follow-up. Conclusion: Using a video-assisted thoracoscopic transaortic modified Morrow procedure through a right infra-axillary minithoracotomy can provide good visualization of the LVOT and hypertrophic ventricular septum, ensure optimal exposure of the mitral valve in the presence of complex mitral subvalvular structures, so that allows satisfactory short-term surgical results.

Objective: To analyze and summarize the diagnosis, treatment and prognosis of granulomatosis with polyangiitis (GPA) with nasal symptoms as the first clinical manifestation. Methods: The data of 18 patients of GPA with nasal mucosal symptoms as the first clinical manifestation from the Department of Otorhinolaryngology Head and Neck Surgery, Shandong Provincial Hospital Affiliated to Shandong First Medical University between 2005 and 2019 was collected, including 8 males and 10 females, aged from 5 to 68 years. Nasal endoscopy, imaging examination, laboratory examination, immunological and histopathological examination of nasal mucosa were completed. All patients were treated with glucocorticoid combined with cyclophosphamide and were followed up for 2 to 15 years. Descriptive statistical method was used for analysis. Results: All the 18 patients had the nasal mucosal symptoms as the first clinical manifestation, including nasal obstruction, running nose and epistaxis. Nasal endoscopy showed swelling, erosion, scab and bleeding of nasal mucosa, and 6 cases had nasal septal perforation. Nasal sinus CT scan showed high density shadow of sinus, as well as hyperostosis and osteosclerosis. CT imaging features of pulmonary showed nodular lesion or patchy infiltration in 12 patients and cavitation was found in 6 cases. Laboratory results showed that 13 cases were positive for anti-neutrophil cytoplasmic antibodies (ANCA), and 5 cases were negative. During follow-up period, thirteen patients were symptomatic controlled and survived; two patients died of disease progression; one patient gave up treatment and died; two patients were lost to follow-up. Conclusions: Nasal symptoms are the first clinical manifestation of GPA. Early diagnosis and early treatment with glucocorticoid combined with cyclophosphamide can effectively improve the survival rate.

OBJECTIVE： To provide reference for rational use of estradiol （E2） preparation in clinic. METHODS： The medical records of outpatients receiving assisted reproductive technology （ART） and E2 preparation [Estradiol valerate tablets （EV）， Complex packing estradiol tablets/estradiol and dydrogesterone tablets （EP）， Estradiol gel （EG）] were collected from the reproductive medicine center of a hospital during Jan. 2016-Mar. 2017. Taking drug instruction as standard， the rationality of medical records was evaluated from aspects of indication， route of administration， contraindication， usage and dosage， treatment course， etc. At the same time， these patients were followed up by telephone or outpatient service， and their pregnancy outcomes and ADR were summarized. RESULTS： A total of 12 646 prescriptions were collected， and 7 222， 3 912， 181 and 1 331 prescriptions used EV， EP， EG and EV+EP， respectively. The types of off-label use included over-indication， over-route and over-contraindication， and the rates of off-label use rates were 100％， 11.73％ and 43.60％， respectively. A total of 5 868 ART patients were involved； 439 patients received fresh embryo transplantation， and 5 429 patients received frozen-thawed embryo transplantation， involving 720 and 11 926 prescriptions， respectively. The rates of off-label use of above E2 preparations were 100％ （except for fresh embryo transplantation patients using EG）. As of Feb. 2018， the infant-holding rates of ART patients using EV， EP， EG and EV+EP were 85.29％， 85.37％， 86.36％ and 85.45％， respectively. No relevant ADR and neonatal birth defect was found. CONCLUSIONS： The phenomenon of off-label use of E2 preparations is widespread in the reproductive medicine center of the hospital. Although there is no indication of related safety risks， evidence-based evaluation should be carried out by enlarging the sample size in clinical practice， and careful use.

As an important component of articular cartilage, type IX collagen plays an important role in regulating homeostasis of bone and cartilage. The mutation or deletion of gene could disequilibrate homeostasis leads to deformity of corresponding bone and joint, and finally causes multiple epiphyseal dysplasia. Moreover, anatomic variation also leads to biomechanics change of corresponding functional unit, combine with micro-environment change caused by change of genes, osteoarthritis and disc degeneration were occurred under the function of stress over and over again. In addition, lack of type IX collagen could effect repair of articular cartilage, intervertebral disc tissue injury. However, musculoskeletal diseases related with type IX collagen has so much not limited this, the reports about it is less for lack of evidence, and need further work to study. Clear relationship of type IX collagen and its disease could provide an effective diagnostic method, and develop a new pathway for follow-up treatment.

Objective: To evaluate the impact of KIT D816 mutation on the salvage therapy in relapsed acute myeloid leukemia (AML) with t(8;21) translocation. Method: The characteristics of the first relapsed AML with t(8;21) translocation from 10 hospitals were retrospectively collected, complete remission (CR(2)) rate after one course salvage chemotherapy and the relationship between KIT mutation and CR(2) rate was analyzed. Results: 68 cases were enrolled in this study, and 30 cases (44.1%) achieved CR(2). All patients received KIT mutation detection, and KIT D816 mutation was identified in 26 cases. The KIT D816 positive group had significantly lower CR(2) compared with non-KIT D816 group (23.1% vs 57.1%, χ(2)=7.559, P=0.006), and patients with longer CR(1) duration achieved significantly higher CR(2) than those with CR(1) duration less than 12 months (74.1% vs 31.9%, χ(2)=9.192, P=0.002). KIT D816 mutation was tightly related to shorter CR(1) duration. No significant difference of 2 years post relapse survival was observed between KIT D816 mutation and non-KIT D816 mutation group. Conclusion: KIT D816 mutation at diagnosis was an adverse factor on the salvage therapy in relapsed AML with t(8;21) translocation, significantly related to shorter CR1 duration, and can be used for prediction of salvage therapy response. KIT D816 mutation could guide the decision-making of salvage therapy in relapsed AML with t(8;21) translocation.

Objective To compare the efficacy between part of ethyl acetate in aerial parts and roots of Astragali Radix (AR), and to provide scientific evidences for the comprehensive utilization of aerial parts of Astragalus membranaceus (APAM). Methods An experimental mouse model of leucopenia was induced by cyclophosphamide, and efficacy indicators combined with NMR based on metabolomic approach were employed to compare the therapeutic effects of part of ethyl acetate in APAM and AR. Results Part of ethyl acetate in APAM and AR increased the contents of white blood cell (WBC), monocytes (MO), lymphocyte (LY), and neutrophils (NE). The levels of six potential endogenous metabolites (isoleucine, leucine, valine, arginine, creatine, and hypoxanthine) were reversed by part of ethyl acetate in APAM, and five potential endogenous metabolites (arginine, aspartate, creatine, GPC, and scyllo-Inositol) were reversed by part of ethyl acetate in AR. Efficacy indexes were 451.83 and 469.17. Conclusion Both parts of ethyl acetate in APAM and AR elevated WBC, the mechanisms of them on leukocytosis were probably related to energy metabolism, amino acids metabolism, choline metabolism, and purine metabolism.
