Objective To study the efficacy and side effects of methotrexate with different protocols in the treatment of ectopic pregnancy (EP). Methods Total of 648 patients who had EP and were treated only with MTX were analysed.Patients were divided into six groups according to protocol: Group 1,100 mg intravenously( IV); Group 2,100 mg, IV, followed by citrovorum factor; Group 3, 20 mg, IV every day for five days; Group 4, 20 mg intramusculary (IM) every day for five days; Group 5, 75 mg,IV; Group 6, 75 mg, IM.Results The rates of repeated MTX injection in group1～6 because of inadequate decrease of hCG were 23.3%,25.0%,21.4%,20.6%,24.4% and 22.4% respectively .Success rates were 87.4%,85.4%,90.5%,92.6%,86.3% and 91.4% respectively.Rates of liver dysfunction were 10.3%,8.3%,64.3%,69.1%,8.7% and 31.0%.Conclusion Single-dose of 75mg MTX IV injection may be the best regimen in the treatment of EP because of the same efficacy but the least side effects.

Objective To study changes of different regulators of G protein signaling(RGS) including RGS2, RGS3 and RGS4 mRNA in aorta and heart of spontaneously hypertensive rats (SHR), as well as their correlation with physiological phenotype of cardiovascular system. Methods Haemodynamic indexes of the cardiovascular system were measured. Heart weight and left ventricular weight were determined to calculate the ratio of heart weight to body mass (HW/BM) as well as left ventricular mass index (LVMI) in both male SHR and Wistar rats. Real-time PCR after RT were performed to determine the level of RGS mRNA in aorta and heart. Results Systolic blood pressure (SBP) of SHR was significantly higher than that of the control (229?29 vs. 121?12 mm Hg, P

The clinical handover, which is associated with the observation of the changes in patients′ status and the implementation of nursing process, plays a vital role in critical care. Also, the quality of clinical hand-over has a far-reaching impact on patient safety due to the complicate condition of critical patients. Over the past few years, lots of studies have focused on the many aspects of clinical handover such as the contents of clinical handover, the standard procedure of clinical handover so as to reduce the risks associated with the unsystematic clinical handover.

Objective To explore the feasibility of biplane-transesophageal echocardiography (Bip-TEE) in measuring the aortic annulus dimension (AAD).Methods Totally 24 patients underwent transcatheter aortic valve implantation (TAVI) were collected,and their AAD was measured by two-dimensional transthoracic echocardiography (2D-TTE),two-dimensional transesophageal echocardiography (2D-TEE),Bip-TEE and three-dimensional transesophageal echocardiography (3D-TEE) respectively.These four methods were compared with each other.The correlation between 3D-TEE measures and other three methods were analyzed.Results The AAD measured by 2D-TTE,2DTEE,Bip-TEE and 3D-TEE were (22.02±2.21)mm,(23.34±2.34)mm,(23.89±2.37)mm,(24.21±2.78)mm,respectively.The differences among 4 groups was significant (F=3.88,P=0.01).No statistically significant differences were found between Bip-TEE and 3D-TEE,2D-TEE and 3DTEE,Bip TEE and 2D-TEE (all P＞0.05).There were significant differences between 2D-TTE and 2D-TEE,2D-TTE and Bip-TEE,2D-TTE and 3D-TEE (all P＜0.05).The AAD measured by 3D-TEE were positively correlated with that of 2D-TTE,2D-TEE,Bip-TE (r=0.79,0.88,0.94,all P＜0.05).Conclusion Bip-TEE is a feasible method to measure the AAD rapidly and can provide reliable measurements for the prosthetic valve size in TAVI.

Objective:To compared the changes of macular microvascular architecture in early stage familial exudative vitreoretinopathy (FEVR) patients with inner retinal layer (IRL) persistence and without IRL persistence.Methods:A retrospective clinical study. From 2017 to 2022, 94 patients with stage 1 FEVR with or without IRL residue and 45 age- and sex-matched healthy volunteers with 45 eyes (normal control group) who were confirmed by ophthalmology examination in Hangzhou Hospital of Optometry Affiliated to Wenzhou Medical University and Zhejiang Provincial People's Hospital were included in the study. According to whether there was IRL residue, the patients were divided into IRL group and non-IRL group, with 22 patients (22 eyes) and 72 patients (72 eyes), respectively. Best corrected visual acuity (BCVA) and optical coherence tomography angiography (OCTA) were performed in all eyes. Superficial vessel density (SCP) and deep vessel density (DCP) of whole image, fovea and parafovea, the area and perimeter of fovea avascular area (FAZ), A-circularity index (AI, perimeter/standard circle perimeter with equal area) and vessel density around the 300 μm width of the FAZ (FD), central macular thickness (CMT) on macular 3 mm × 3 mm scan on OCTA were measured.Results:SCP and DCP of whole image ( F=10.774, 4.583) and parafovea ( F=10.433, 3.912), CMT ( F=171.940) in IRL group and non-IRL group on macular 3 mm × 3 mm scan on OCTA were significantly lower than that in normal persons ( P<0.05). There were significant differences among three groups of the area of FAZ ( F=4.315), AI ( F=3.413), FD-300 ( F=13.592) ( P<0.05). BCVA were worst in IRL group ( P<0.05). Conclusions:Blood flow density decreased in macular area of FEVR patients. CMT is significantly thicker than normal population. The FAZ area of the foveal IRL residual eyes is small and irregular, with worse BCVA and lower macular blood density.

We aimed to evaluate the effectiveness and safety of single-course initial regimens in patients with low-risk gestational trophoblastic neoplasia (GTN). In this trial (NCT01823315), 276 patients were analyzed. Patients were allocated to three initiated regimens: single-course methotrexate (MTX), single-course MTX + dactinomycin (ACTD), and multi-course MTX (control arm). The primary endpoint was the complete remission (CR) rate by initial drug(s). The primary CR rate was 64.4% with multi-course MTX in the control arm. For the single-course MTX arm, the CR rate was 35.8% by one course; it increased to 59.3% after subsequent multi-course MTX, with non-inferiority to the control (difference -5.1%,95% confidence interval (CI) -19.4% to 9.2%, P = 0.014). After further treatment with multi-course ACTD, the CR rate (93.3%) was similar to that of the control (95.2%, P = 0.577). For the single-course MTX + ACTD arm, the CR rate was 46.7% by one course, which increased to 89.1% after subsequent multi-course, with non-inferiority (difference 24.7%, 95% CI 12.8%-36.6%, P < 0.001) to the control. It was similar to the CR rate by MTX and further ACTD in the control arm (89.1% vs. 95.2%, P =0.135). Four patients experienced recurrence, with no death, during the 2-year follow-up. We demonstrated that chemotherapy initiation with single-course MTX may be an alternative regimen for patients with low-risk GTN.

We conducted a prospective study to assess the non-inferiority of adjuvant chemotherapy alone versus adjuvant concurrent chemoradiotherapy (CCRT) as an alternative strategy for patients with early-stage (FIGO 2009 stage IB-IIA) cervical cancer having risk factors after surgery. The condition was assessed in terms of prognosis, adverse effects, and quality of life. This randomized trial involved nine centers across China. Eligible patients were randomized to receive adjuvant chemotherapy or CCRT after surgery. The primary end-point was progression-free survival (PFS). From December 2012 to December 2014, 337 patients were subjected to randomization. Final analysis included 329 patients, including 165 in the adjuvant chemotherapy group and 164 in the adjuvant CCRT group. The median follow-up was 72.1 months. The three-year PFS rates were both 91.9%, and the five-year OS was 90.6% versus 90.0% in adjuvant chemotherapy and CCRT groups, respectively. No significant differences were observed in the PFS or OS between groups. The adjusted HR for PFS was 0.854 (95% confidence interval 0.415-1.757; P = 0.667) favoring adjuvant chemotherapy, excluding the predefined non-inferiority boundary of 1.9. The chemotherapy group showed a tendency toward good quality of life. In comparison with post-operative adjuvant CCRT, adjuvant chemotherapy treatment showed non-inferior efficacy in patients with early-stage cervical cancer having pathological risk factors. Adjuvant chemotherapy alone is a favorable alternative post-operative treatment.
