ABSTRACT

The three-day-old female infant was admitted to the hospital due to respiratory distress after birth. She was born premature at 36+2 weeks gestational age. Prenatal ultrasound suggested abnormal development of the fetal liver vessels, and she had dyspnea that required respiratory support after birth. Chest X-ray indicated an enlarged cardiac silhouette, and cardiac ultrasound revealed enlargement of the right atrium and right ventricle. Diagnosis of hepatic hemangioma with arteriovenous fistula was confirmed through liver ultrasound and abdominal enhanced CT. At 19 days old, she underwent ligation of the hepatic artery under general anesthesia, which led to an improvement in cardiac function and she was subsequently discharged. Genetic testing revealed a mutation in the ACVRL1 gene, which was inherited from the mother. The article primarily introduces a case of neonatal heart failure caused by hepatic hemangioma with arteriovenous fistula, and multi-disciplinary diagnosis and treatment of this disease.

ABSTRACT

A boy, aged 3 hours, was admitted due to a prenatal diagnosis of fetal hydrops at 3 hours after resuscitation for birth asphyxia. Prenatal examination at 5 months of gestation showed massive ascites in the fetus, and after birth, the boy had the manifestations of systemic hydroderma, massive ascites, coarse face, and hepatomegaly. Genetic testing revealed heterozygous mutations in the SLC17A5 gene, and there was a significant increase in urinary free sialic acid. Placental pathology showed extensive vacuolization in villous stromal cells, Hofbauer cells, cytotrophoblast cells, and syncytiotrophoblast cells in human placental chorionic villi. The boy was finally diagnosed with free sialic acid storage disorders (FSASDs). This is the first case of FSASDs with the initial symptom of fetal hydrops reported in China. The possibility of FSASDs should be considered for cases with non-immune hydrops fetalis, and examinations such as placental pathology and urinary free sialic acid may help with early diagnosis and clinical decision making.

ABSTRACT

Background Pesticide poisoning is not only a common acute poisoning, but also an indispensable public health problem. It is important to describe and analyze the epidemic characteristics and trends of pesticide poisoning for its prevention and control. Objective To understand the epidemiological characteristics and trends of pesticide poisoning in Jiaxing from 2008 to 2020, and provide a basis for making effective intervention measures. Methods The relevant information of pesticide poisoning cases in Jiaxing from 2008 to 2020 was collected through the Occupational Disease and Occupational Health Information Monitoring System of the China Disease Prevention and Control Information System, and the demographic information was obtained from the statistical yearbook of Jiaxing. Joinpoint regression models were used to analyze trends in overall, gender, age, season, type of poisoning, and type of pesticide among poisoned individuals. Results A total of 3109 cases of pesticide poisoning were reported in Jiaxing City from 2008 to 2020. The overall pesticide poisoning incidence trended downward from 2008 to 2014, with an annual percent change (APC) of −9.0% (95%CI: −16.6%-−0.7%). The female pesticide poisoning incidence trended downward from 2008 to 2015, with an APC of −8.6% (95%CI: −13.9%-−2.9%). The 18-34 age group showed a decreasing trend of pesticide poisoning incidence from 2008 to 2015, with an APC of −11.0% (95%Cl: −17.4%-4.3%), and an increasing trend from 2015 to 2020, with an APC of 18.5% (95%Cl: 4.7%-34.0%). The >60 age group showed a decreasing trend of pesticide poisoning incidence from 2008 to 2014, with an APC of -12.9% (95%Cl: −20.4%-−4.7%). The second quarter showed an increasing trend of pesticide poisoning incidence from 2010 to 2020, with an APC of 4.4% (95%CI: 0.3%-8.5%); the third quarter showed a decreasing trend, with an APC of −4.9% (95%CI: −8.6%-−1.1%); the fourth quarter showed an increasing trend from 2015 to 2020, with an APC of 17.8% (95%CI: 4.4%-33.0%). Productive poisoning showed a decreasing trend, with an APC of −11.1% (95%CI: −16.2%-−5.7%); self-poisoning showed a decreasing trend from 2008 to 2014, with an APC of -9.5% (95%CI: −17.4%-−0.7%), and an increasing trend from 2014 to 2020, with an APC of 10.2% (95%CI: 0.5%-20.8%). The incidences of poisoning by herbicides, fungicides, and mixed formulations all showed an increasing trend from 2008 through 2020, with an APC of 8.6% (95%CI: 5.8%-11.5%), 9.1% (95%CI: 0.3%-18.7%), and 193.3% (95%CI: 11.6%-671.0%), respectively; the incidence of poisoning by other types of pesticides showed a decreasing trend from 2008 to 2020, with an APC of −14.1% (95%CI: −23.7%-−3.2%). Conclusion The overall reported pesticide poisoning incidents in Jiaxing City present a decline then a rise in 2008 to 2020. Relevant departments should take timely measures to prevent and reduce the occurrence of pesticide poisoning according to the changing characteristics and occurrence trends of local pesticide poisonings.

ABSTRACT

This study aims to investigate the role of slient mating-type information regulation 2 homolog 1(SIRT1)/tuberous sclerosis complex 2(TSC2)/mammalian target of rapamycin(mTOR) signaling pathways in the Periplaneta americana extract CⅡ-3-induced senescence of human leukemia K562 cells. K562 cells were cultured in vitro and treated with 0(control), 5, 10, 20, 40, 80, and 160 μg·mL~(-1) of P. americana extract CⅡ-3. Cell counting kit-8(CCK-8) and flow cytometry were employed to examine the proliferation and cell cycle of the K562 cells. Senescence-associated β-galactosidase stain kit(SA-β-gal) was used to detect the positive rate of senescent cells. Mitochondrial membrane potential was detected by flow cytometry. The relative mRNA level of telomerase reverse transcriptase(TERT) was determined by fluorescence quantitative PCR. The mRNA and protein levels of SIRT1, TSC2, and mTOR were determined by fluorescence quantitative PCR and Western blot, respectively. The results showed that CⅡ-3 significantly inhibited the proliferation of K562 cells and the treatment with 80 μg·mL~(-1) CⅡ-3 for 72 h had the highest inhibition rate. Therefore, 80 μg·mL~(-1) CⅡ-3 treatment for 72 h was selected as the standard for subsequent experiments. Compared with the control group, CⅡ-3 increased the proportion of cells arrested in G_0/G_1 phase, decreased the proportion of cells in S phase, increased the positive rate of SA-β-Gal staining, elevated the mitochondrial membrane potential and down-regulated the mRNA expression of TERT. Furthermore, the mRNA expression of SIRT1 and TSC2 was down-regulated, while the mRNA expression of mTOR was up-regulated. The protein expression of SIRT1 and p-TSC2 was down-regulated, while the protein expression of p-mTOR was up-regulated. The results indicated that P. americana extract CⅡ-3 induced the senescence of K562 cells via the SIRT1/mTOR signaling pathway.

ABSTRACT

On the basis of retaining the technical identification system of medical negligence, the Medical Association Identification Rules of Medical Damage mainly provides technical services for various types of conciliation work about doctor-patient dispute. Its identification work is still influenced by the thinking of medical negligence technical identification and has certain administrative color. Guidance for Judicial Expertise of Medical Malpractice is mainly reflected that the trial of civil cases and pre-trial mediation of courts need service. Its procedures and evidence review are strictly required by the litigation rules and has the characteristics of public legal services provided as a third-party neutral institution. Technical identification of medical damage, whether organized by the Medical Association or the forensic identification institutions, is carried out under the background of the current Regulations on the Prevention and Treatment of Medical Disputes and the Civil Code of the People's Republic of China; both have a corresponding positive role in regulating the medical damage identification activities, and have also laid a certain foundation for the establishment of a unified identification system in the future in China. To understand the different characteristics of the medical damage identification rules issued by the Chinese Medical Association and the Ministry of Justice, and to improve the understanding of the standardization of the forensic identification of medical damage, a comparative study was conducted on Medical Association Identification Rules of Medical Damage and Guidance for Judicial Expertise of Medical Malpractice from seven aspects: Concept and legal status, entrust of identification, identification acceptance, identification procedures, identification presentation meeting, theory of medical malpractice evaluation, consequences and causality of medical damage. The subject of evaluation, the function of evidence review, the role of consulting experts, the technical standard system of malpractice evaluation and other contents were emphatically analyzed.

ABSTRACT

Objective:To analyze the prognostic factors and evaluate the accuracy of existing survival prediction models in patients with lung cancer-derived spinal metastases who have undergone open surgery.Methods:According to the inclusion criteria, the data of 76 patients with spinal metastasis of lung cancer who underwent open surgery in the department of Orthopedics in Guangdong Provincial People's Hospital were collected from January 2019 to November 2021. The relationship between the number of bone metastasis, pathological type, visceral metastasis, epidermal growth factor receptor mutation, serum alkaline phosphatase (ALP), hemoglobin (Hb), Frankel grade and postoperative survival time in 76 cases was analyzed by Cox logical regression analysis and Kaplan-Meier method to determine the potential prognostic factors. The accuracy of Tomita score, Tokuhashi revised score, Katagiri New score, New England Spinal Metastasis Score score (NESMS) and Skeletal Oncology Research Group (SORG) machine learning algorithm in predicting postoperative survival time was verified by drawing receiver operating characteristic (ROC) curve.Results:The median follow-up time of the patients was 18.0 months (2.3-36.0 months). The median survival time was 12.6 months [95% CI (10.8, 14.4)]. The survival rates at 6 and 12 months after operation were 71.6% and 52.0%, respectively. Multivariate regression analysis showed that ALP [ HR=0.23, 95% CI (0.11, 0.48), P<0.001], Hb [ HR=4.48, 95% CI (2.07, 9.70), P< 0.001] and EGFR mutation [ HR=2.22, 95% CI (1.04, 4.76), P=0.040] were independent predictors of prognosis. The accuracy of Tomita score, Tokuhashi revised score (2005), Katagiri New score and NESMS score in predicting 1-year mortality was 58.7%, 65.7%, 70.5% and 65% respectively, and the accuracy in predicting 6-month mortality was 63.7%, 62.2%, 61.2% and 56.8% respectively. The accuracy of SORG machine learning algorithm in predicting 1-year and 90 d mortality was 81.1%, 67.5%, respectively. Conclusion:No EGFR mutation, ALP>164 U/L and Hb≤125 g/L were risk factors affecting the survival of patients with spinal metastasis of lung cancer. SORG machine learning algorithm has good accuracy in predicting the postoperative survival rate of patients with lung cancer spinal metastasis.

ABSTRACT

Objective:To investigate the clinicopathological features, diagnosis, treatment and prognosis of simultaneous double primary gynecological malignant tumors.Methods:A total of 23 patients with simultaneous double primary malignant tumors of female reproductive system primarily treated in Beijing Obstetrics and Gynecology Hospital, Capital Medical University from January 1, 2010 to December 31, 2020 were retrospectively collected. The age, symptoms, tumor stage, tumor type, treatment and prognosis of patients were collected and followed up.Results:(1) The number of patients with gynecological tumors in our hospital increased year by year in the past 11 years. A total of 8 987 patients with gynecological malignant tumors were firstly diagnosed and cured in our hospital, including 3 474 cases of cervical cancer, 3 484 cases of endometrial cancer, 1 329 cases of ovarian malignancies, 171 cases of fallopian tube cancer, 182 cases of uterine sarcoma, 42 cases of vaginal cancer, 192 cases of vulvar cancer, 110 cases of trophoblastic tumor and 3 cases of other gynecological malignancies. The top three cancers were endometrial cancer, cervical cancer and ovarian malignancies. (2) There were 23 patients identified with simultaneous double primary gynecological tumors in the past 11 years, accounting for 0.26% (23/8 987) of female malignant tumors. There were 3 cases of cervical cancer complicated with endometrial cancer, 3 cases of cervical cancer complicated with ovarian cancer, 16 cases of endometrial cancer combined with ovarian cancer, and 1 patient with endometrial cancer combined with fallopian tube cancer. (3) All 23 patients underwent surgical treatment. According to the first diagnosis of the tumor, the surgical methods included cervical cancer radical surgery, endometrial cancer staging surgery and ovarian cancer cytoreductive surgery. After operation, radiotherapy and chemotherapy were supplemented according to the results of pathological examination and tumor staging. (4) The age of 23 patients ranged from 28 to 66 years, with an average age of (49.4±9.7) years. All patients had vaginal bleeding or conscious pelvic mass as their main clinical manifestation. The clinical stage was found in 7 patients (30%, 7/23) with advanced gynecological cancer (stage Ⅲ-Ⅳ), and 16 patients (70%, 16/23) with early stage gynecological cancer (stage Ⅰ-Ⅱ). According to the nonspecific tumor markers, 13 patients (57%, 13/23) had elevated CA 125 and CA 199. (5) Among the 23 patients, 1 case was uncontrolled and 3 cases recurred during the follow-up period, and the sites of uncontrolled or recurred were all located in the abdominopelvic cavity. Three cases died. Among the 3 patients who died, 1 patient was an uncontrolled patient, whose tumor type was cervical adenosquamous cell carcinoma combined with ovarian clear cell adenocarcinoma. The overall survival time was 19 months with postoperative supplementary radiotherapy and chemotherapy. There were 2 recurrent patients, and the tumor types were endometrioid carcinoma complicated with high-grade serous ovarian carcinoma and ovarian endometrioid carcinoma, respectively. After surgery, all patients received supplementary chemotherapy and recurred 60 and 21 months after surgery, respectively, and the overall survival time was 78 and 28 months, respectively. Another patient recurred 43 months after surgery, and survived with tumor for 14 months after recurrence. The remaining 19 patients were tumor-free and were still being followed up. Conclusions:There are no specific markers for simultaneous double primary gynecological malignant tumors. The most common clinical symptoms are vaginal bleeding or pelvic mass. The treatment principle of simultaneous double primary gynecological malignant tumor is the same as that of single gynecological malignant tumor, but need to be taken into account the characteristics of two tumors. Surgery is the main treatment method, and radiotherapy and chemotherapy play an important auxiliary role. The prognosis of simultaneous double primary gynecological malignancies is related to the late stage of the two malignancies.

ABSTRACT

Supermicrosurgery is a hot topic in the field of microsurgery and reconstruction. The core concept of supermicrosurgery is precision and minimally invasive, which coincides with the concept of maxillofacial reconstruction. Oral and maxillofacial regions play an important role in aesthetics and function, and the structure of oral and maxillofacial tissues is complex. Various types of flaps, especially vascularised free flaps, are required for the repair of various complex maxillofacial defects. However, at present, conventional microsurgery does meet the requirement of mandibular reconstruction in special cases. Super microsurgical technique can further supplement the deficiency of conventional methods of repair and reconstruction in maxillofacial reconstruction. Under the guidance, many new methods of maxillofacial surgery have inevitably emerged. The application of supermicrosurgery in maxillofacial head and neck is still in its early stage, and there are still many difficulties to overcome and many technical issues to be furtherresolved. Supermicrosurgery is not only an advanced technique, but also an advanced concept in surgery. Supermicrosurgery is expected to show its clinical value in oral and maxillofacial reconstruction. In this paper, the application of supermicrosurgery in maxillofacial reconstruction is reviewed and its application prospect is prospected.

ABSTRACT

Medication-related osteonecrosis of the jaw (MRONJ) is a serious adverse event related to administration of antiresorptive or antiangiogenic medications. With the increasing usage of bone-modifying agents in cancer therapy, the incidence of MRONJ enhanced gradually, which affects the life quality of patients and interferes with cancer therapy. In 2019, Multinational Association of Supportive Care in Cancer (MASCC), International Society of Oral Oncology (ISOO) and American Society of Clinical Oncology (ASCO) convened a multidisciplinary Expert Panel to evaluate the evidence and formulate recommendations on practices in the prevention and management of MRONJ in patients with cancer. The present article made an interpretation of Medication-Related Osteonecrosis of the Jaw: MASCC/ISOO/ASCO Clinical Practice Guideline so as to provide clinicians with diagnostic and therapeutic approaches for cancer patients with MRONJ.

ABSTRACT

Objective To evaluate the efficacy and safety of basiliximab (BAS) and antithymocyte globulin (ATG) in immune induction therapy in kidney transplantation by systematic review and Meta-analysis. Methods Prospective randomized controlled clinical trials screening and comparing BAS and ATG in immune induction therapy in kidney transplantation were systematically searched from global databases, screened and compared. The quality of clinical trials was evaluated by Jadad scoring system and data extraction was performed. The effects of BAS and ATG on the incidence of acute rejection, survival rate of kidney allografts, survival rate of recipients, incidence of delayed graft function, infection, cytomegalovirus infection, malignant tumor, leukopenia and thrombocytopenia at 1 year after kidney transplantation were analyzed. Results A total of 10 clinical trials in English consisting of 1 721 kidney transplant recipients were searched, including 883 cases in the ATG group and 838 cases in the BAS group. No significant differences were observed in the incidence of acute rejection, survival rate of kidney allografts, survival rate of recipients, incidence of delayed graft function, infection, cytomegalovirus infection and thrombocytopenia at postoperative 1 year between the ATG and BAS groups (all P > 0.05). The incidence of malignant tumor and leukopenia at postoperative 1 year in the ATG group were significantly higher than those in the BAS group (both P < 0.05). Conclusions The use of ATG and BAS for immune induction therapy in kidney transplantation yield equivalent efficacy at postoperative 1 year, but BAS is safer than ATG. Clinical trials related to stratified analyses of immune risk are urgently required to achieve individualized precision treatment.

ABSTRACT

Objective: To analyse the clinical application of thoracodorsal artery perforator flaps (TDAPF) in the repair of head and neck defects. Methods: A retrospective review was conducted on 38 patients with oral and maxillofacial head and neck malignant tumors who underwent radical resection of oral and oropharyngeal carcinoma and TDAPF repair in the Department of Oral and Maxillofacial Head and Neck Oncology of the Ninth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from June 2017 to November 2018. Among them, 32 were males and 6 were females, aged 30-74 years. Flap size, vessel pedicle length, diameter and number of perforators, and flap fat thickness were recorded and counted. Elasti Meter and Skin Fibro Meter were applied to measure the skin elasticity and hardness in the donor areas of 4 kinds of skin flaps before the flap preparation. SPSS 19.0 statistical software was used for statistical analysis of the data. Results: All the flaps survived (100%). The mean elasticity of TDAPF [(41.2±12.9) N/m] was significantly lower than that of anterolateral thigh [(77.6±23.3) N/m, χ²=88.89, P<0.05], anterolateral thigh [(62.6±17.7) N/m, χ²=59.99, P<0.05] and or forearm flap [(51.7±8.6) N/m, χ²=37.82, P<0.05]. The hardness of TDAPF [(0.037±0.016) N] was also significantly lower than that of anterolateral femoral [(0.088±0.019) N, F=93.27, P<0.05], anteromedial femoral [(0.059±0.020) N, F=25.71, P<0.05] or forearm flap [(0.062±0.016) N, F=29.11, P<0.05]. Follow-up period ranged from 2 to 14 months. The 38 patients treated with TDAPF had a good recovery of the functions in the recipient areas, and the scars of the donor areas were not obvious after surgery, without serious complications. Conclusion: TDAPF is suitable for reconstruction of head and neck defect, with ductile texture and good recovery of the morphology and function of head and neck.

ABSTRACT

Objective:To analyze the risk factors of first endotracheal extubation failure and the related poor outcomes of extubation failure in intubated very low birth weight (VLBW) and extremely low birth weight (ELBW) infants.Methods:The VLBW/ELBW infants intubated in the first 24 hours, and admitted from June 2016 to December 2017 in Neonatal Intensive Care Unit of the Children′s Hospital of Fudan University were recruited in the study, and they were divided into 2 groups of the extubation-failure group and the extubation-success group based on whether being reintubated in 72 hours after the extubation.The clinical data of all children were collected, and risk factors and the short-term outcomes were compared between the 2 groups.Results:One hundred and twenty-six VLBW/ELBW infants including 25 extubation-failure infants and 101 extubation-success infants were recruited, the extubation fai-lure rate was 19.8%.Extubation-failure infants had lower gestational age and lower birth weight compared with those of extubation-success group [gestational age: (27.9±2.1) weeks vs.(28.9±1.6)weeks; birth weight: 990(847-1 200) g vs.1 170(1 060-1 350) g], and the differences were statistically significant (all P<0.05). The multiple Logistic analysis demonstrated that lower gestational age was the independent risk factor of extubation failure( OR=0.92, 95% CI: 0.86-0.99, P<0.05). The outcome analysis showed that the combined outcomes of moderate-to-severe bronchopulmonary dysplasia(BPD) and death in the extubation-failure group were significantly higher than those in the extubation-success group ( OR=3.33, 95% CI: 1.28-8.63, P<0.05)after being adjusted by gestational age.The secondary outcomes of brain magnetic resonance imaging(MRI) abnormality rate in the extubation-failure group was significantly higher compared with the extubation-success group ( OR=3.93, 95% CI: 1.22-12.60, P<0.05), and the mechanical ventilation duration was significantly longer as well in the extubation-failure group compared with that in the extubation-success group[10.1 d (6.9 d, 20.9 d) vs.3.6 d(1.1 d, 8.6 d)], and the difference was statistically significant( P<0.05). The rest secondary outcomes were not significantly different between the 2 groups(all P>0.05). Conclusions:A high rate of extubation failure in VLBW/ELBW infants was a common issue, and the lower gestational age is the independent risk factor for extubation failure.Extubation failure potentially increases the risk of moderate-to-severe BPD or death in VLBW/ELBW infants.

ABSTRACT

Objective@#This study aimed to identify proteins related to paclitaxel and carboplatin chemoresistance in cervical cancer. @*Methods@#Quantitative proteomic analysis was performed on normal SiHa cells and those treated with paclitaxel and carboplatin for 14 days, with isobaric tags for relative and absolute quantitation (iTRAQ) analysis. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were used to identify related processes and differentially expressed proteins. @*Results@#A total of 67 and 96 differentially expressed proteins were identified in the paclitaxel- and carboplatin- treated groups, respectively. GO and KEGG enrichment analyses identified 53 (43 upregulated and 10 downregulated) and 85 differentially expressed proteins (70 upregulated and 15 downregulated) in the paclitaxel- and carboplatin-treated groups, respectively. The cell counting kit-8 results revealed that APOA1 was overexpressed in both the paclitaxel- and carboplatin- resistant SiHa cells compared with the control cells. Immunohistochemistry showed that APOA1 was highly expressed in the paclitaxel- and carboplatin- resistant squamous cell carcinoma of the cervix. @*Conclusion@#This study is the first to use iTRAQ to identify paclitaxel- and carboplatin- resistance proteins in cervical cells. We identified several proteins previously unassociated with paclitaxel and carboplatin resistance in cervical cancer, thereby expanding our understanding of paclitaxel and carboplatin resistance mechanisms. Moreover, these findings indicate that the APOA1 protein could serve as a potential marker for monitoring and predicting paclitaxel and carboplatin resistance levels.

ABSTRACT

From January 15 to March 3, 2020, seven editions of the guidelines for the diagnosis and treatment of COVID-19 have been issued successively by the National Health Commission of the People's Republic of China, and the guidelines' name was changed from Guidelines for Diagnosis and Treatment of Novel Coronavirus Pneumonia to Diagnosis and Treatment for COVID-19. It optimized and perfected the etiology, clinical manifestations and types, diagnostic procedures and specific treatment measures of the disease, so that the clinical management of the cases was more scientific. In the revision process of guidelines for diagnosis and treatment, forensic medicine experts have also made some positive suggestions on clinical diagnosis and treatment. Especially regarding the pathological changes of COVID-19, they have repeatedly called for rapid autopsy at different levels. With the support, understanding and cooperation of all parties, pathological examination of more than ten cases of the remains were carried out, which made an important contribution to the understanding of the clinical characteristics and pathological characteristics of the disease and the improvement of treatment plans.

ABSTRACT

Objective To detect the expressions of epidermal growth factor-like domain 7 (EGFL7) and P185 protein in breast cancer tissues and serum,and to analyze the correlation between the expression levels of EGFL7 and P185 in tissues and clinicopathological parameters of breast cancer patients. Methods Sixty patients with breast cancer in Hunan Cancer Hospital from March 2016 to March 2018 were collected as observation group,and 60 patients with breast benign lesions in the hospital during the same period were selec-ted as control group. The expressions of EGFL7 and P185 protein in tissues of patients in the two groups were detected by immunohistochemical two-step method,and the levels of EGFL7 and P185 protein in serum of patients in the two groups were detected by enzyme-linked immunosorbent assay (ELISA). The relationships between the expressions of EGFL7 and P185 protein and clinicopathological parameters of breast cancer patients were analyzed. Results The positive rates of EGFL7 in tissues in the observation group and the control group were 65. 00% (39 / 60)and 28. 33% (17 / 60),and there was a significant difference between the two groups (χ2 = 16. 205,P < 0. 001). The positive rates of P185 in tissues in the two groups were 43. 33% (26 / 60)and 15. 00% (9 / 60),and there was a significant difference between the two groups (χ2 = 11. 657,P = 0. 001). The serum levels of EGFL7 protein in the observation group and the control group were (3. 39 ± 0. 38)μg/ ml and (2. 75 ± 0. 31)μg/ ml respectively,with a significant difference (t = 10. 109,P < 0. 001). The serum levels of P185 protein in the two groups were (7. 12 ± 0. 75)μg/ ml and (6. 08 ± 0. 62)μg/ ml respectively, with a significant difference (t = 8. 279,P < 0. 001). The positive expression of EGFL7 protein was closely related to tumor size (χ2 = 6. 128,P = 0. 013),TNM stage (χ2 = 7. 781,P = 0. 005)and metastasis (χ2 =5. 444,P = 0. 020). The positive expression of P185 protein was closely related to tumor size (χ2 = 8. 910, P = 0. 003)and TNM stage (χ2 = 8. 024,P = 0. 005). Conclusion The levels of EGFL7 and P185 protein are high in breast cancer tissues and serum,and their positive expressions are related to tumor size and TNM stage. EGFL7 and P185 proteins play important roles in the progression of breast cancer.

ABSTRACT

OBJECTIVE: To investigate the clinicopathological effects of taking tamoxifen(TAM)on endometrium after breast cancer operation.METHODS: From January 2011 to December 2017,622 cases of breast cancer were treated in Beijing Obstetrics and Gynecology Hospital,Capital Medical University.Among them,197 patients took TAM,and 59 patients who took TAM underwent hysteroscopic surgery due to abnormal vaginal bleeding or ultrasound endometrial abnormalities.The 59 patients were divided into premenopausal and postmenopausal groups to analyze the pathological condition;the medication time was defined as 3 years and 5 years,so as to observe the endometrial pathology.Set the endometrial abnormal hyperplasia includes: endometrial cancer and the endometrial atypical hyperplasia, and the rest are benign endometrial lesions and the normal endometrium, and then analyze the ultrasound criteria for abnormal endometrial thickening in premenopausal and postmenopausal according to the endometrial pathology.RESULTS: Among the 197 patients who took TAM after breast cancer,59 patients underwent hysteroscopic surgery,32.2%(19/59)of them visited the hospital because of abnormal vaginal bleeding,76.3%(45/59)were pathologically confirmed to have a lesion,in which the endometrial polyps was with the highest incidence.The incidence of endometrial cancer after menopause was 20.0%(6/30),premenopausal endometrial cancer 3.4%(1/29),and atypical hyperplasia before menopause was 20.7%(6/29).When taking TAM for more than 3 or 5 years,the incidence of endometrial cancer and atypical hyperplasia increased.Premenopausal ultrasound endometrial thickness is associated with abnormal endometrial hyperplasia(P=0.035).The endometrial thickness 15 mm can be used as the best diagnostic ultrasound cut-off for the diagnosis of premenopausal abnormal endometrial thickening. Postmenopausal ultrasound endometrial thickness was not associated with abnormal endometrial hyperplasia(P=0.631).CONCLUSION: Taking TAM after breast cancer surgery can result in endometrial polyps and endometrial hyperplasia.Premenopausal patients can also have endometrial cancer and atypical hyperplasia,so the endometrial monitoring should not be ignored.Those who take TAM for more than 3 years need to be more alert to the occurrence of endometrial lesions.The premenopausal B-ultrasound endometrial thickness 15 mm can be used as the best diagnostic ultrasound cut-off for the diagnosis of abnormal endometrial thickening. After the menopause, the endometrial thickness of 5 mm was still used as the standard for abnormal endometrial thickening.
