To explore the application of vaginal color ultrasound in the diagnosis and treatment of ectopic pregnancy. Methods: From August 2018 to May 2019, 90 patients with suspected ectopic pregnancy who were treated in our hospital were selected as the study objects. Abdominal color ultrasound and vaginal ultrasound were performed respectively to compare the diagnosis results of the two methods. Result: The detection rate of transvaginal ultrasound was higher than that of abdominal ultrasound (P < 0.05); the accuracy rate of transvaginal ultrasound was significantly higher than that of abdominal ultrasound (P < 0.05); the main parts of ectopic pregnancy were ampulla, isthmus and umbrella, and the main types were ruptured, unruptured and obsolete. Conclusion: The application of transvaginal ultrasound in the diagnosis of ectopic pregnancy has the advantages of high accuracy and detection rate, fast examination speed, simple operation, etc. it is of great significance to retain the fertility of patients and is wworthy popularizing.

Objective: To explore the effect and value of transvaginal ultrasound in screening early ectopic pregnancy. Methods: A total of 146 patients with ectopic pregnancy in our hospital were selected. The patients' entry time was from May 2018 to December 2020. 146 patients were divided into two groups. The control group was screened by abdominal ultrasound with 73 cases, and the experimental group was screened by vaginal ultrasound with 73 cases. The uterine adnexal mass, pelvic effusion, peritoneal effusion and diagnostic accuracy were detected. Results: The positive number of abdominal ultrasound was significantly higher than that of vaginal ultrasound; In the detection process of abdominal ultrasound, 54 cases of ectopic pregnancy, 19 cases of non-ectopic pregnancy, the detection rate was 73.97%, 26 cases of ectopic pregnancy, 47 cases of non-ectopic pregnancy, the detection rate was 32.62%. Conclusion: The accuracy of transvaginal ultrasound is relatively high, and the accuracy of ectopic pregnancy examined by transvaginal ultrasound is higher, which is more friendly to patients, less traumatic and high operability. It can provide more accurate reports for patients and relieve the psychological pressure of patients, which is worthy of application in actual screening.

Objective: The main objective of our study is to compare transabdominal and transvaginal ultrasound in assessment of polycystic ovaries. Study Design: Cross Sectional Comparative study. Setting: Jinnah Medical College and Hospital Karachi. Period: January 2016 to January 2017. Material & Methods: 200 married females were selected with complaints of irregular menses, hirsutism, obesity and infertility and age group 18-45 years. Patients with already diagnosed polycystic ovaries or on hormonal treatment were excluded. Results: Out of 200 patients, 54 patient shows poly cystic ovaries both on trans abdominal and Trans vaginal ultrasound, 16 patients on Trans vaginal ultrasound only  but not on trans abdominal ultrasound in which 13 patients were very obese. Rest of the patients had normal ovaries on both types of ultrasound examinations. The prevalence of polycystic ovaries noted by transabdominal ultrasound is 27% (54/200) overall and by TVS ultrasound is 35% (70/200). Conclusion: PCOS is quite a common endocrine complaint. Our results suggest that prevalence of PCO is 27% by trans-abdominal u/s and 35% by TVS. The Mean volume of ovary is greater in women with polycystic ovaries but there is no significant difference seen in prevalence of polycystic ovaries diagnosed by both ultrasound examinations. Although it has been observed that TVS is better than transabdominal U/S in detection of PCO but our study shows that the two methods are almost analogous except in obese patient where TVS displayed better results.

Pregnancy Of Unknown Location

Background: Pregnancy of unknown location (PUL) is defined as the absence of intrauterine or extrauterine sac and Beta Human Chorionic Gonadotropin levels (β-HCG) above the discriminatory zone of 1500 mIU/ml. It should be noted that PUL is not always an ectopic; however, by measuring the trends of serum β-HCG, we can determine the outcome of a PUL. Objective: This study aims to identify the various trends β-HCG levels in early pregnancy and evaluate the role of β-HCG in the management strategy. Methods: We conducted a prospective observational study of pregnant women suspected with early pregnancy. Cases were classified as having a pregnancy of unknown location (PUL) by transvaginal ultrasound and ß-HCG greater than 1000 mIU/ml. Expectant management was done until there was a definite outcome. All the collected data were analyzed by employing the chi-square test using SPSS version 20. Results: Among 1200 women who had early first trimester scans, 70 women who fulfilled our criteria of PUL and ß-HCG > 1000 mIU/ml were recruited in this study. In our study, the mean age of the participants was 30±5.6yrs, and the overall mean serum ß-HCG was 3030±522 mIU/ml. The most common outcome observed was an ectopic pregnancy, 47% in our study. We also found the rate of failing pregnancy was 27%, and that of intrauterine pregnancy (IUP) was 25%. Overall, in PUL patients diagnosed with ectopic pregnancy, 9% behaved like IUP, and 4% had an atypical trend in their ß-HCG. Those who had an IUP, 11% had a suboptimal increase in ß-HCG. Conclusion: PUL rate in our unit was 6%. Majority of the outcome of PUL was ectopic in our study. Every case of PUL should be managed based on the initial ß-HCG values, clinical assessments and upon the consent of the patient.

Oracle bone script recognition (OBSR) has been a fundamental problem in research on oracle bone scripts for decades. Despite being intensively studied, existing OBSR methods are still subject to limitations regarding recognition accuracy, speed and robustness. Furthermore, the dependency of these methods on expert knowledge hinders the adoption of OBSR systems by the general public and also discourages social outreach of research outputs. Addressing these issues, this study proposes an encoding-based OBSR system that applies image pre-processing techniques to encode oracle images into small matrices and recognize oracle characters in the encoding space. We tested our methods on a collection of oracle bones from the Yin Ruins in XiaoTun village, and achieved a high accuracy rate of 99% within a time range of milliseconds.
