Objective To investigate the clinical features, diagnosis and treatments of pelvic abscess with endometriosis. Methods A retrospective analysis was performed on 129 cases of pelvic abscess in Peking Union Medical College Hospital from January 2000 to January 2016. Among them, 34 women with endometriosis were divided into the study group and the others were in the control group. The clinical characteristics, therapeutic regimens and outcomes were compared. Results (1) General conditions:there were no statistic differences between the two groups in age, WBC, serum CA125, intrauterine device in use, pelvic inflammatory disease history;while incidence rates of dysmenorrhea (65%, 22/34) and infertility (21%, 7/34) in the study group were higher than those in the control group (all P<0.05). (2) Clinical manifestations:fever, abdominal pain and pelvic mass were the main symptoms in two groups. The incidence rates of septic shock were 12%(4/34) in the study group and 2%(2/95) in the control group (P<0.05). (3) Treatment:treatment with puncture all failed in the study group (7/7) and surgeries were required. In contrast, there was only 1/19 treatment failure with puncture in the control group. The puncture failure rates were statistically significant (P<0.05). Compared with the study group and the control group, there were significant differences (P<0.05) in the operation time of laparoscopic surgery [(76±41) versus (53±21) minutes] and of laparotomy [(168±58) versus (116±35) minutes], intra-operative blood loss of laparoscopic surgery [(216±296) versus (43±36) ml] and of laparotomy [(448 ± 431) versus (145 ± 24) ml]. Conclusions Pelvic abscess in women with endometriosis is more severe and refractory to antibiotics and puncture treatment. Active surgical intervention is required. Although surgical procedures are often difficult, prognosis is comparatively satisfied.

As one of the most difficult-to-cure neuropsychiatric disorders in clinical practice， schizophrenia is mainly manifested by behavioral abnormalities and multidimensional cognitive dysfunction， and the recurrence rate and disability rate of the disease are increasing year by year， which seriously affects patients' social functioning and quality of life， and even threatens the physical and mental health of the surrounding population. At present， the treatment of schizophrenia is mainly based on antipsychotic drugs combined with psychotherapeutic techniques， which have limited long-term therapeutic effects and a high relapse rate. Traditional Chinese medicine （TCM） boasts the advantages of multi-targets， multi-pathways， multi-links， and multi-levels， and plays a crucial role in the prevention and treatment of schizophrenia and its prognosis. Phosphatidylinositol 3-kinase （PI3K） is widely present in cells and is involved in the regulation of protein synthesis and apoptosis， and the different isoforms of protein kinase B （Akt） are of great significance in cell growth， oxidative stress， neuronal development and other processes. In recent years， a large number of studies have found that the PI3K/Akt signaling pathway is closely related to schizophrenia. Through regulating the PI3K/Akt signaling pathway， TCM monomers and TCM compounds mainly affect key signaling molecules such as mammalian target of rapamycin （mTOR）， glycogen synthase kinase （GSK）， glucose transporter （GLUT） for glucose uptake and transport， and nuclear factor E₂-associated factor 2 （Nrf2）， which organize the intracellular network of centers and regulate the formation and plasticity of neuronal synapse， and they play an important role in mitigating schizophrenia by regulating the processes of cell proliferation， migration and apoptosis of neurons， and has the advantages of multi-targets， all-encompassing and low toxicity. This article analyzes and explains the mechanism of TCM intervention in the PI3K/Akt signaling pathway against schizophrenia， in order to provide a theoretical basis and reference for the prevention and treatment of schizophrenia by TCM.

Objective:To evaluate the feasibility of a new ultrasonic parameter to assess right ventricular-pulmonary artery (RV-PA) coupling in patients with acute pulmonary embolism (APE).Methods:A retrospective analysis was performed in 140 patients with APE diagnosed by computed tomography pulmonary angiography (CTPA) in the Second Affiliated Hospital of Harbin Medical University from August 2017 to June 2020. According to the tricuspid annular plane systolic excursion/pulmonary arterial systolic pressure (TAPSE/PASP) ratio cutoff value 0.40 mm/mmHg reported by the European Society of Cardiology in 2020, the patients were divided into the coupling group ( n=99) and the uncoupling group ( n=41). The conventional ultrasonic parameters of the 2 groups were measured, and then several ultrasonic parameter ratios were obtained. The new ultrasonic parameter, which can replace the TAPSE/PASP ratio, was screened out by Spearman correlation analysis, and ROC curve was plotted to calculate the diagnostic efficacy of this parameter. Results:①Compared with the coupling group, patients in the uncoupling group were older and more likely to be accompanied by dyspnea and venous thrombosis in the lower extremities (all P<0.05), but there was no significant difference in other general data(all P>0.05); ②Compared with the coupling group, tricuspid regurgitation velocity (TRV), tricuspid regurgitation pressure gradient(TRPG), PASP, right ventricle end-diastolic transverse diameter(RVTD), inferior vena cava(IVC) diameter and the ratio of early diastolic tricuspid inflow to tricuspid lateral annular velocity(E/e′), in the uncoupling group increased significantly (all P<0.05), and TAPSE, peak systolic velocity of tricuspid annulus(s′), TAPSE/PASP ratio, TAPSE/TRPG ratio, TAPSE/RVTD ratio and s′/TRPG ratio decreased significantly (all P<0.05); ③The TAPSE/TRPG ratio was highly correlated with TAPSE/PASP ratio ( rs=0.970, P<0.001); The TAPSE/TRPG ratio was still highly correlated with TAPSE/PASP ratio in the uncoupling and coupling groups ( rs=0.966, 0.922; all P<0.001). ④ROC analysis showed that the area under curve for TAPSE/TRPG in diagnosing RV-PA coupling was 0.992. At the cutoff of TAPSE/TRPG <0.625 mm/mmHg for indicating RV-PA coupling, the sensitivity and specificity were 97.6% and 92.9%, respectively. Conclusions:TAPSE/TRPG ratio can be used as a new ultrasonic parameter to reflect RV-PA coupling, which is helpful for clinical identification of APE patients with high risk and poor prognosis.
