ABSTRACT
Although tumor treatment models have been continuously improved in clinical practice, cancer remains a serious threat to human health. The effect of probiotics on tumor therapy has received extensive attention. As a common colonizer of the intestinal mucosa, Akkermansia muciniphila(AKK) has a well-defined role in metabolic diseases, but its complex role in tumor development and therapeutic efficacy has not been fully elucidated. The unique properties and physiological roles of AKK play an important role in different solid tumors and it may be a potential biomarker. This article provides a review of previous studies and proposes clinical strategies to influence the abundance of AKK to provide a theoretical reference for the development of next-generation probiotics and the reshaping of the tumor treatment landscape.
ABSTRACT
Objective:To probe into the causes, reconstructive strategies, and repair outcomes of asymmetric eyelid configuration after blepharoplasty.Methods:All 73 patients (14 males and 59 females) with asymmetric double eyelid after blepharoplasty were recruited between July 2013 and June 2018 from Department of Plastic and Burns Surgery, West China Hospital, Sichuan University. The patients aged from 18 years to 42 years with the median age of 27 years. The new double eyelid line was designed pre-operation. Releasing subcutaneous adhesion of upper eyelid entirely, trimming inferior orbicularis oculi, adjusting and comparing the attachment position of bilateral levator aponeurosis were performed during surgery. Patients and surgeons marked the appearance of double eyelid both before and after repair operation, results of which were analyzed by t-test.Results:All 73 patients obtained improved double eyelid with primary healing. During follow-up from 8 to 12 months, repaired double eyelid showed satisfactory configuration with smooth natural double eyelid line and symmetric bilateral double eyelid. Of the 73 patients, 3 (4.1%) complaint rough double eyelid line, for whom re-fixation through small incision were adopted and no complication was observed during follow-up time. Scores by patients and surgeons were both significantly better after surgery.Conclusions:Analyzing the causes of asymmetric eyelid after double-eyelid blepharoplasty and repairing it contribute to aesthetic pleasing reconstructed double eyelid.
ABSTRACT
The outbreak of coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 has rapidly spread globally. Cancer patients are at a higher risk of being infected with the coronavirus and are more likely to develop severe complications, as compared to the general population. The increasing spread of COVID-19 presents challenges for the clinical care of patients with gynecological malignancies. Concerted efforts should be put into managing gynecological malignancies in an orderly manner by strictly implementing the measures that are specifically developed for controlling the spread of COVID-19. We have drafted Recommendations on Management of Gynecological Malignancies during the COVID-19 Pandemic based on our experience on controlling COVID-19 pandemic in China. We recommend that patients with gynecological malignancies should be managed in hierarchical and individualized manners in combination with local conditions related to COVID-19. Medical care decision should be balanced between controlling COVID-19 pandemic spread and timely diagnosis and treatment for gynecologic oncology patients.

ABSTRACT
BACKGROUND: Choriocarcinoma is a kind of trophoblastic neoplasm with highly aggressive phenotypes. Forkhead box D3 (FoxD3) is an embryonic and trophoblastic stem cel transcription factor. It plays important roles in different physical and pathological situations such as embryogenesis, carcinogenesis and tumor progression. OBJECTIVE:To investigate the role of FoxD3 in choriocarcinoma malignancy and the possible mechanism. METHODS:The human choriocarcinoma JAR cel line was employed in this study. The mRNA and protein expressions of genes were measured by quantitative RT-PCR (qRT-PCR) and western blot, respectively. The FoxD3 specific short hair RNA was applied to down-regulate gene expression. The cel proliferation was evaluatedin vitro by cel counting assay andin vivo by tumor growth. The migration/invasion was determined by transwel assay. The profile of FoxD3 targeted genes was investigated with an Agilent microarray and verified by qRT-PCR. RESULTS AND CONCLUSION: The FoxD3 mRNA and protein expressions in JAR cells were significantly higher than those in primarily cultured normal trophoblastic cells. Knockdown of FoxD3 by short hair RNA in JAR cells could inhibit cell proliferation and migration/invasionin vitro, and suppress thetumor growth with decreased β-human chorionic gonadotropin secretionin vivo. A profile of seven focal adhesion molecules (ITGA5, ITGB6, THBS4, COL6A3, VTN, NRXN3 and NLGN1) was verified to be targeted by FoxD3. Furthermore, knockdown of FoxD3 by short hair RNA could decrease the activation of focal adhesion kinase. All these findings suggest the overexpression of FoxD3 can contribute to the aggressive phenotype of choriocarcinoma JAR cells by regulating the profile of focal adhesion molecules and focal adhesion kinase.

ABSTRACT
Aim To explore the role of progesterone re-ceptor B ( PRB ) in regulation of medroxyprogesterone acetate ( MPA) sensitivity in endometrial cancer cells, and to investigate the effect of MPA on the biological character in Ishikawa cells infected with shRNA targe-ting PRB gene. Methods Ishikawa cells were stably transfected with PRB shRNA using lentivirus to knock-down endogenous PRB expression. Real-time fluores-cent quantitative PCR was applied to confirm the knockdown effect. MTT assay, flow cytometry and cell invasion assay were applied to detect the influence of MPA on endometrial cancer cell proliferation, apopto-sis and invasion. We also used Western blot assay to detect the effect of MPA induced the activation of ERK/MAPK signal pathway. Results Recombinant lentiviral vector expressing shRNA targeting PRB gene was successfully established, results of real-time PCR and Western blot showed that compared with control group, PRB expression in Ishikawa cells infected with shRNA decreased obviously ( P <0.01 ); MPA could repress endometrial cancer cells proliferation and inva-sion, meanwhile promoted its apoptosis ( P <0.01 ) . However, the effect was almost reverse in Ishikawa cells infected with shRNA. Furthermore, MPA induced ERK/MAPK activation in Ishikawa cells infected with shRNA. Conclusions PRB plays a role in regulating therapeutic sensitivity of MPA in endometrial cancer cells;and for Ishikawa cells infected with shRNA tar-geting PRB gene, MPA has effects on the biological character via pERK1/2-MAPK signal pathway.

ABSTRACT
Based on special biological characteristics and prognosis, the incidence of gastroesophageal junction adenocarcinoma (GEJA) has rapidly increased over recent years, and its diagnosis and treatment remain controversial. Compared with simple surgery, neo-adjuvant and adjuvant therapies can improve the survival of patients with locally advanced GEJA. Under neo-adjuvant therapy, neo-adjuvant chemoradiation is superior to neo-adjuvant chemotherapy alone for improving the resectability, maintaining loco-regional control, and improving the quality of life of the patient. The combination of this therapy with targeted drugs may further increase the ef-ficacy of GEJA. Most data on GEJA-treated patients were obtained from randomized clinical studies on esophageal cancer or gastric cancer. Thus, prospective randomized controlled studies with a large sample size should be performed to optimize the strategy of neo-adjuvant and adjuvant therapies, and further improve the treatment outcome. In this article, studies on the comprehensive treatment of GEJA were reviewed.
ABSTRACT
Objective To study the value of hCG ratio of blood in peritoneal cavity versus venous blood (RPhCG/VhcG) in diagnosis of early ectopic pregnancy (EP).Methods From Mar.2009 to Oct.2012,268 cases with EP (EP group) and 53 women with intrauterine pregnancy with haemoperitoneum (hIUP) (hIUP group) from International Peace Maternity and Child Health Hospital of Shanghai Jiaotong University School of Medicine,Shanghai 6th People Hospital and Shanghai Jiangwan Hospital were enrolled in this prospective study.The HCG of all subjective were measured in blood in peritonea cavity and venous blood,then calculate the ratio of RPhCG/VhCG.Scatter point analysis and ROC were used to differentiate EP,determine threshold of hlUP and evaluate the sensitivity,specificity and accuracy in diagnosis EP preoperatively.Results The mean RPhCG/VhCG; of EP group was 4.35,which was significantly higher than 0.81 in hIUP group (P ＜ 0.01).Scatter point analysis showed that the threshold value of RPhCG/VhCG between ectopic pregnancy and hIUP was 1.0.The overall sensitivity of RPhCG/VhcG in the diagnosis of EP was 98％,the specificity was 100％,the positive predictive value was 100％ and the negtive predictive value was 93％.Conclusion RPhCG/VhCG ＞ 1.0 could be used to diagnose and differentiate EP from hIUP accurately.
ABSTRACT
The depth of anesthesia can be assessed by means of analyzing heart rate variability (HRV). Continuous wavelet transform (CWT) was used to obtain more accurate results on the changes of low frequency (LF) and high frequency (HF) components of HRV signals (RR interval sequences) before and after general anesthesia. With wavelet scale transformed into frequency, the obtained time-frequency energy distributions showed that the LF and HF components of HRV signals were suppressed after general anesthesia, while the LF/HF ratio reduced from 9.0219 to 3.5573. The time-frequency distribution showed that CWT can more accurately locate the abrupt changes in time-domain, giving more precise range of frequency changing, compared with traditional time-frequency analysis method. The results indicated that, as a new time-frequency analysis method of analyzing HRV during general anesthesia, CWT provides more accurate time-frequency location, and consequently, offers more accurate monitoring results of anesthesia depth.
