Objective:To compare the diagnostic efficacy of 68Ga-PSMA-11 PET/ CT and multi-parameter magnetic resonance imaging (mpMRI) for pelvic lymph node metastases in prostate cancer patients who received neoadjuvant endocrinology or not after initial diagnosis. Methods:Data of 52 patients with moderate and high-risk prostate cancer admitted to Xijing Hospital from February to October 2023, aged (65.8±6.6) years, preoperative prostate-specific antigen (PSA) 26.67 (13.09, 84.89) ng/ml, were retrospectively analyzed. Before operation, there were 28 cases of cT 2stage, 16 cases of cT 3 stage and 8 cases of cT 4 stage. There were 22 cases of cN 0 and 30 cases of cN 1. All patients underwent 68Ga-PSMA-11 PET/CT and mpMRI at the same time, and were diagnosed positive lymph nodes in 28 and 21 cases, respectively. Risk stratification were high risk in 45 cases, and medium risk in 7 cases. According to the preoperative endocrine treatment, they were divided into the newly diagnosed group without treatment (24 cases) and the endocrine treated group (28 cases), whose ages were (65.0±7.1) years and (66.8±6.1) years, respectively. Preoperative PSA was 26.17 (16.73, 61.18) ng/ml and 27.32 (11.94, 130.18) ng/ml, respectively. Gleason scores ≤7 were in 10 cases (41.7%) and 6 cases (21.4%), and Gleason scores >7 were in 14 cases (58.3%) and 22 cases (78.6%), respectively. There were 15 (62.5%) and 13 (46.4%) cases of cT 1-2 stage, and 9 (37.5%) and 15 (53.6%) cases of cT 3-4 stage, respectively. There were 16 (66.7%) and 6 (21.4%) cases of stage N 0, 8 (33.3%) and 22 (78.6%) cases of stage N 1, respectively. There were 22 (91.7%) and 20 (71.4%) cases of stage M 0, 2 (8.3%) and 8 (28.6%) cases of stage M 1, respectively. PET/CT diagnosis of lymph node positive was in 9 cases (37.5%) and 19 cases (67.9%), and mpMRI diagnosis of lymph node positive was in 5 cases (20.8%) and 16 cases (57.1%). The number of positive lymph nodes diagnosed by PET/CT was 13 (72.2%) and 47 (90.1%), and the number of positive lymph nodes diagnosed by mpMRI was 8 (44.4%) and 32 (61.5%). There was no significant difference ( P>0.05). All patients underwent radical prostatectomy as well as enlarged pelvic lymph node resection. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of the two imaging examinations in the diagnosis of lymph node metastasis were compared according to the results of postoperative pathological examination of lymph nodes. Receiver operating characteristic (ROC) curve was used to compare the accuracy of the two imaging tests in the diagnosis of pelvic lymph node metastasis in the newly diagnosed untreated group and the endocrine treated group. Results:In this study, of 52 cases, 26 (50.0%) had positive lymph nodes by pathological examination. In this study, a total of 681 lymph nodes were dissected, with 70 lymph nodes (10.28%) being pathologically positive, and the positive rate of 26 patients was 17.99% (70/389). The PET/CT and mpMRI detection rates of 26 node-positive patients were 92.3% (24/26) and 57.7% (15/26), respectively. There were 9 (37.5%) and 17 (60.7%) lymph node positive patients in the untreated group and the endocrine therapy group, respectively. There were 320 and 361 lymph nodes were clear, with 18 (5.6%) and 52 (14.4%) positive lymph nodes, respectively. The detection rates of PET/CT and mpMRI were 88.89% (8/9) and 94.12% (16/17)in the untreated group, and 44.44% (4/9) and 64.71% (11/17)in the endocrine treated group, respectively. In the newly treated group, the area under the curve (AUC) of PET/CT and mpMRI for diagnosing positive lymph nodes were 0.911 and 0.689 ( P=0.027), the sensitivity were 88.9% and 44.4%, and the specificity were 93.3% and 93.3%, respectively. PPV were 88.9% and 80.0%, and NPV were 93.3% and 73.7%, respectively. In the endocrine therapy group, the AUC of PET/CT and mpMRI for lymph node positive diagnosis were 0.834 and 0.596 ( P=0.011), the sensitivity were 94.1% and 64.7%, the specificity were 72.7% and 54.5%, and the PPV were 84.2% and 68.8%, respectively. NPV were 88.9% and 50.0%, respectively. Conclusions:For prostate cancer patients, regardless of whether they receive neoadjuvant endocrine therapy, 68Ga-PSMA-11 PET/CT can accurately detect pelvic lymph node metastasis, and the diagnostic efficacy is significantly better than that of mpMRI.

Pregnancy in patients with Eisenmenger syndrome (ES) is associated with high maternal mortality rates of 30%‒50%, or even up to 65% in the case of a cesarean section (Yuan, 2016). Here, we report a case of term pregnancy complicated with ES and severe pulmonary artery hypertension (PAH), which was managed by a multidisciplinary team (MDT) and resulted in an uncomplicated delivery via elective cesarean section. The goal of this study is to emphasize the importance of multidisciplinary approach in the management of pregnancy with ES, which can profoundly improve maternal and infant outcomes.

In the past few years, there has seen an increase in the detection rate of early upper gastric cancer. Early upper gastric cancer is of good prognosis. How to further enhance the postoperative quality of life of patients has increasingly become an issue of concern. This has naturally given rise to function-preserving proximal gastrectomy. However, due to its damage to the original structure of cardia and its vicinity, proximal gastrectomy is prone to postoperative reflux. To prevent postoperative reflux, various ways of digestive tract reconstruction have emerged one after another, but the optimal way thereof remains controversial. Therefore, reducing postoperative reflux through an appropriate way of digestive tract reconstruction has been taken as a focus of proximal gastrectomy. Esophagogastric anastomosis with seromuscular flap technique, as a way of digestive tract reconstruction, builds an "artificial cardia" on the basis of guarantee of normal entry of food into the digestive tract, and functions against postoperative reflux. For its good anti-reflux effect, eso-phagogastric anastomosis with seromuscular flap technique has gradually become a research focus. On top of the latest research progress at home and abroad and relevant evidence-based medicine, the authors provide on the principles, key points, improvement, postoperative status, and applica-tion of esophagogastric anastomosis with seromuscular flap technique in laparoscopic proximal gastrectomy.

Objective:To explore the clinical value of introducing 68Ga PSMA PET / CT into the prostate cancer(PCa)screening clinic, and to analyze the incidence rate and biopsy of PCa in the screening clinic of our hospital. Methods:The data of the people who participated in PCa screening in the urology screening clinic of our hospital from March 2021 to November 2021 were retrospectively analyzed. Serum PSA was used as the screening index. The subjects with PSA≥4ng/ml were first examined by mpMRI to find suspicious nodules, and the positive ones were further examined by 68Ga-PSMA PET/CT to determine the lesions.The puncture target was outlined, and systematic+ targeted puncture was conducted under ultrasound guidance. The age, PSA distribution, puncture detection rate, Gleason score and clinical stage of patients with PCa were recorded. Results:A total of 1 079 subjects were included in the screening, with an average age of (63.9±9.9)(ranging 40-92) years old, and 249 patients (23.1%, 249/1 079) with PSA≥4ng/ml. Among them, 87 cases (87/249, 34.9%) received mpMRI, and 34 cases (34/249, 13.7%) had PI-RADS score ≥3 points. These 34 patients with suspected nodules on MRI were further scanned with 68Ga-PSMA PET/CT, and 11 cases (11/249, 4.4%) had abnormal uptake of PSMA nuclide. A total of 32 patients (12 patients with PSA abnormalities and 20 patients with positive imaging) finally received prostate biopsy, and 11 patients were diagnosed with PCa, with a positive detection rate of 34.4% (11/32), accounting for 1.0% (11/1 079) of the screening population. Among them, 20 patients with positive imaging (9 patients with only mpMRI positive and 11 patients with both mpMRI and 68Ga-PSMA PET/CT positive) underwent system + targeted fusion biopsy, and the positive rate was 45% (9/20). 12 patients (only PSA abnormal) underwent routine systematic puncture biopsy, and the positive detection rate was 16.7% (2/12). The difference between the two groups was statistically significant ( P<0.05). Among the patients with confirmed PCa, 27.3% (3/11) had Gleason score less than 7, and 72.7% (8/11) had Gleason score≥7. Localized PCa (≤T 2) accounted for 45.4% (5/11), local progression (T 3-T 4) accounted for 18.2% (2/11), and metastatic PCa suggested by 68Ga-PSMA PET/CT accounted for 36.4% (4/11), including 3 systemic multiple bone metastases and one bone metastasis with distant lymph node metastasis. Clinically significant PCa accounted for 90.9% (10/11) of the confirmed patients, and the proportion of high-risk patients in localized or locally advanced PCa was 71.4% (5/7). Conclusions:In PCa screening, if 68Ga-PSMA PET/CT is introduced on the basis of conventional mpMRI, the detection rate of clinically meaningful PCa can be improved. Combined with targeted puncture, tumor lesions can be found early and the screening efficiency of PCa can be improved. In this study, the detection rate of PCa in outpatient screening reached 1.0%. In confirmed cases, the proportion of high-risk patients and metastatic patients was higher.

Objective:To study the efficacy of 68Ga-PSMA PET/CT in evaluating lymph node metastases (LNMs) in patients with prostate cancer (PCa). Methods:Patients who recieved 68Ga-PSMA PET /CT examination in the First Affiliated Hospital of Air Force Military Medical University from July 2021 to February 2022 were enrolled. The patients’ age was (64.4±6.1) years old, with median total prostate specific antigen (tPSA) 34.5 (6.1-99.0) ng/ ml, including PSA<10ng/ ml in 12 cases, 10-20ng/ ml in 21 cases, and > 20 ng/ml in 25 cases. Preoperative clinical staging: 1 case in T 1 stage, 38 cases in T 2 stage, 16 cases in T 3stage, 3 cases in T 4 stage. Preoperative Gleason score of 10 cases was <7, 20 cases was 7, and 28 cases was > 7. According to D 'Amico risk grouping criteria, there were 8 cases in the low-risk group, 20 cases in the medium-risk group and 30 cases in the high-risk group. Preoperative examination of 68Ga-PSMA PET/CT showed no distant metastasis such as visceral metastasis and bone metastasis. All patients underwent radical prostatectomy and pelvic lymph node dissection. The following patients were excluded: patients received preoperative prostate surgery, patients received endocrine therapy, chemotherapy and radiotherapy for prostate cancer before surgery, a history of other malignant tumors in the past 2 years, biopsy pathological diagnosis of neuroendocrine cell prostate cancer and other special types of prostate cancer, prior history of major pelvic surgery, etc. Radical prostatectomy was performed. 38 patients received laparoscopic surgery and 20 patients received robot-assisted laparoscopic surgery. The sensitivity and specificity of 68Ga-PSMA PET /CT for the diagnosis of lymph node metastasis of prostate cancer were calculated according to the comparison of lymph node metastasis in postoperative pathological results and preoperative examination. Results:Postoperative pathological diagnosis: Gleason score of 9 cases was <7, 19 cases was 7, and 30 cases was >7. 37 cases were in pT 2 stage, 17 cases in pT 3 stage, and 4 cases in T 4 stage. There were 12 cases (20.7%) of positive resection margin, and 7 cases (12.1%) of lymphatic fistula. There were 10 patients with lymph node metastasis diagnosed by 68Ga-PSMA PET/CT before surgery, and 17 positive lymph node regions. A total of 11 patients were pathologically positive in lymph nodes, and a total of 20 lymph nodes regions were positive. Based on the number of patients, the specificity and sensitivity of 68Ga-PSMA PET /CT in diagnosing lymph node metastasis in patients were 97.9% (46/47) and 81.2% (9/11), respectively. Based on the number of regional lymph nodes, the specificity and sensitivity of 68Ga-PSMA PET /CT for regional lymph node diagnosis were 99.4%(326/328) and 75.0%(15/20), respectively. The specificity of lymph node metastasis in the external iliac group, the internal iliac group and the obturator group were 100.0%(114/114), 99.1%(110/111) and 98.1%(101/103), and the sensitivity was 100.0%(2/2), 60.00%(3/5) and 69.2%(9/13), respectively. Conclusion:68Ga-PSMA PET/CT can be used as a strong tool for precise guidance of PLND in PCa patients.

Objective: To evaluate the efficacy of Tuina (Chinese therapeutic massage) manipulation plus horse-riding squat exercise in treating knee osteoarthritis (KOA) and optimize the combining protocol. Methods: Based on a 2×2 factorial design, 120 eligible KOA patients were randomized into a manipulation group (group A1B2), a manipulation plus horse-riding squat group (group A1B1), a sitting knee-adjustment group (group A2B2 group), and a sitting knee-adjustment plus horse-riding squat group (group A2B1), with 30 cases in each group. The intervention was conducted three times a week, lasting for four weeks. The Western Ontario and McMaster Universities osteoarthritis index (WOMAC) was taken as the major measure for efficacy evaluation (including three component scores, pain, stiffness, and daily function, and total score). Results: The three component scores (pain, stiffness, and daily function) and the total score of WOMAC showed significant differences after the intervention in the four groups (P<0.05). There were significant inter-group differences in the WOMAC stiffness score amongst the four groups after the intervention (P<0.05). In group A1B1, the step length, stride, walking speed, and knee joint flexion angle changed significantly after treatment (P<0.05). After the intervention, the step length changed significantly in group A1B2 (P<0.05), and the walking speed changed significantly in group A2B1 (P<0.05). There were no significant differences in the step length, stride, walking speed, or knee joint flexion angle among the four groups (P>0.05). The extensor peak torque at 180 °/s changed significantly in group A1B2 after treatment (P<0.05). Neither the intra-group nor the inter-group comparisons of the four groups revealed significant differences in the other isokinetic muscle strength parameters (P>0.05). The main effect of manipulation showed significant in affecting the WOMAC pain and total scores (P<0.05). The main effect of horse-riding squat exercise showed significant in affecting the WOMAC pain and stiffness scores (P<0.05). Conclusion: The four treatment protocols all can improve the symptoms of KOA, for instance, relieving pain and stiffness, and enhancing daily function. Group A2B1 produces the most eminent effect in relieving joint stiffness. The main effects of both manipulation and horse-riding squat exercise are significant in reducing pain. Besides, the main effect of horse-riding squat exercise is significant in relieving joint stiffness.

Bronchopulmonary dysplasia is one of the most common complications of preterm infants.The main pathological feature is dysplasia of the alveoli and pulmonary microvessels.Vitamin D is a steroid hormone.By binding to vitamin D receptors, it can protect the barrier function of alveolar epithelium, promote pulmonary vascularization, inhibit pulmonary fibrosis, regulate immune function, and repair damaged lung epithelial cells.It is beneficial to lung development and the improvement of lung function in preterm infants.Therefore, monitoring the level of vitamin D in the perinatal period and supplementing with appropriate doses is expected to be one of the ways to reduce the occurrence of moderate and severe bronchopulmonary dysplasia and improve the lung development of preterm infants.

Objective:To investigate the clinical efficacy of laparoscopic-assisted inters-phincteric resection (ISR) with different surgical approaches for low rectal cancer.Methods:The retrospective cohort study was conducted. The clinicopathological data of 90 patients with low rectal cancer who were admitted to the Second Affiliated Hospital of Fujian Medical University from January 2016 to December 2020 were collected. There were 58 males and 32 females, aged (60±9)years. Of 90 patients, 60 cases underwent laparoscopic assisted ISR with transpelvic approach, 30 cases underwent laparoscopic assisted ISR with transabdominal and transanal mixed approach. Observation indicators: (1) clinicopathological characteristics of patients with transpelvic approach and mixed approach; (2) intraoperative and postoperative conditions of patients with transpelvic approach and mixed approach; (3) postoperative complications of patients with transpelvic approach and mixed approach; (4) follow-up. Follow-up was conducted by telephone interview and outpatient examination once every 3 months within postoperative 3 years, once every six months in the postoperative 3 to 5 years and once a year after postoperative 5 years to detect tumor recurrence and metastasis, and survival of patients.Follow-up was up to March 2021 or patient death. Measurement data with normal distribution were represented as Mean± SD, and the t test was used for comparison between groups. Measurement data with skewed distribution were expressed as M(range), and comparison between groups was conducted using the non-parametric Mann-Whitney U test. Count data were expressed as absolute numbers or percentages, and comparison between groups was performed using the chi-square test or Fisher exact probability. Comparison of ordinal data was analyzed by the non-parametric rank sum test. Kaplan-Meier method was used to draw survival curves and calculate survival rates, and survival analysis was performed by the Log-Rank test. Results:(1) Clinicopathological characteristics of patients with transpelvic approach and mixed approach. The sex (males, females), distance from the distal margin of tumor to anal margin were 34, 26, (4.5±0.5)cm for patients with transpelvic approach, versus 24, 6, (3.5±0.5)cm for patients with mixed approach, respectively, showing significant differences between them ( χ2=4.75, t=8.35, P<0.05). (2) Intraoperative and postoperative conditions of patients with transpelvic approach and mixed approach. The operation time, volume of intraoperative blood loss, distance from the postoperative anastomosis to anal margin were (187±9)minutes, 50(range, 20?200)mL, (3.4±0.7)cm for patients with transpelvic approach, versus (256±12)minuets, 100(range, 20?200)mL, (2.6±0.7)cm for patients with mixed approach, showing significant differences between them ( t=?26.99, Z=?2.48, t=4.67, P<0.05). None of the 90 patients had a positive distal margin. The stoma reversal rates of patients with transpelvic and mixed approach were 93.3%(56/60) and 90.0%(27/30), respectively. Of the 60 patients with transpelvic approach, 3 cases had no stoma reversal due to anastomotic complications, and 1 case was not yet to the reversal time. Of the 30 patients with mixed approach, 2 cases had no stoma reversal due to anastomotic complications, and 1 case was not yet to the reversal time. The 1-, 3-month Wexner scores after stoma reversal were 15(range, 12?17), 12(range, 10?14) for patients with transpelvic approach, versus 16(range, 14?18), 14(range, 12?16) for patients with mixed approach, showing significant differences between them ( Z=?4.97, ?5.49, P<0.05). The 6-month Wexner score after stoma reversal was 10(range, 9?12) for patients with transpelvic approach, versus 11(range, 8?12) for patients with mixed approach, showing no significant difference between them ( Z=?1.59, P>0.05). (3) Postoperative complications of patients with transpelvic approach and mixed approach. The complications occurred to 16 patients with transpelvic approach and 9 patients with mixed approach, respectively, showing no significant difference between them ( χ2=0.11, P>0.05). Cases with postoperative anastomotic fistula, cases with anastomotic bleeding, cases with anastomotic stenosis, cases with intestinal obstruction, cases with incision infection, cases with urinary retention, cases with pelvic infection, cases with pulmonary infection, cases with incisional hernia, cases with chylous fistula, cases with abdominal and pelvic abscess were 5, 2, 1, 7, 0, 1, 5, 3, 1, 1, 1 for patients with transpelvic approach, versus 6, 3, 2, 2, 2, 1, 2, 3, 1, 1, 1 for patients with mixed approach, showing no significant difference between them ( P>0.05). The same patient could have multiple postoperative complications. (4) Follow-up. All the 90 patients were followed up for 27(range, 6?62)months. The follow-up time of 60 patients with transpelvic approach was 27(range, 8?62)months. The follow-up time of 30 patients with mixed approach was 28(range, 6?53)months. Of the 60 patients with transpelvic approach, 3 cases had local recurrence, 4 cases had liver metastasis, 3 cases had lung metastasis, and all of them survived with tumor. Of the 30 patients with mixed approach, 1 case had local recurrence, 2 cases had liver metastasis, 1 case had lung metastasis, and all of them survived with tumor. There was no death. The 3-year disease-free survival rates of patients with transpelvic approach and mixed approach were 84.7% and 87.9%, respectively, showing no significant difference between them ( χ2=0.39, P>0.05). Conclusions:Lapa-roscopic assisted ISR via transpelvic approach or mixed approach for low rectal cancer are safe and feasible. Compared with transanal mixed approach, the transpelvic approach of laparoscopic-assisted ISR has shorter operation time, less volume of intraoperative blood loss and longer distance from the postoperative anastomosis to anal margin.
