Objective To Investigate the clinical relationship between the interstitial cystitis and female hormone imbalance.Methods A retrospective analysis of 58 cases of IC female patients in our hospital from January 2006 to April 2012.The patients' age ranged from 21 to 76 years,and the average age was 40.2±12.4 years old.The suffering time of disease ranged from 9 to 120 months,and the average duration was 64.3±55.7 months.At the 1st,12th,22th day of the menstrual cycle,the O'Leary-Sant and PUF questionnaires were used to score,in order to analyze the relationship between IC symptoms and the menstrual cycle.The symptoms scores between postmenopausal patients and No menopause patients were compared.At the same time,the medical records and follow-ups were reviewed for all patients.Results 51 cases of IC premenopausal female patients suffered more urinary frequency,urgency,and bladder pain during the menstrual period.The proportion respectively were 54.9 ％ (28/51),60.8％ (31/51).The O'Leary-Sant scores of the 1st day were more significant difference than the12th and the 22th day (P＜0.05),but there was no significant difference between the 12th day and the 22th day (P＞0.05).The PUF scores of the 1st day were significant different than the 12th and the 22th day (P＜0.05),but there was no significant difference between the 12th day and the 22th day (P＞0.05).The average scores of O'Leary-Sant and PUF in 7 postmenopausal patients were statistically significant lower than non-menopausal patients (P＜0.05).The incidence of 58 cases with uterine fibroids,breast hyperplasia,ovarian cysts,endometriosis (48.3％,41.4％,5.2％,13.8％) were higher than the average persons (P=0.001,0.460,0.001,0.048),which were significantly higher than the incidence of the general population (30.0％,40.0％,0.3％,7.0％) excepting breast hyperplasia.Conclusions The symptoms of urinary frequency,urgency,and bladder pain in IC patients were more serious during the menstrual period than the other periods.The symptoms of the non-postmenopausal patients were more serious than the postmenopausal patients.The incidence of IC patients associated with hormone imbalance diseases was higher than the general persons,indicating that the fluctuation of female hormone level was likely to be one cause of IC onset.

In order to investigate biological functions of the 14-3-3 genes and their response to abiotic stress, two cDNAs (designated as Ta14R1 and Ta14R2) encoding putative 14-3-3 proteins were isolated from wheat by PCR and rapid amplification of cDNA end (RACE) technique. The cDNA of Ta14R1 is 999bp and encodes a protein of 262 amino acids, while the cDNA of Ta14R2 is 897bp in length and encodes a protein of 261 amino acids. Transient expression assays using Ta14R1/Ta14R2-GFP fusion constructs indicated that Ta14R1 and Ta14R2 were located in cytoplasm and cell membrane but not in chloroplasts. Real-time quantitative (RT-PCR) analysis revealed that Ta14R1 and Ta14R2 were differentially expressed in wheat tissues and significantly up-regulated in roots and shoots 1d after germination, indicating they may play a role in process of seed germination. The expression of the two genes in roots and leaves were significantly induced by plant hormone ABA, as well as heat, cold and drought treatments, suggesting that the two 14-3-3 genes in wheat may be involved in ABA dependent stress-responding pathway and response to heat, cold and drought stress.

ObjectiveTo investigate the effect of different cytopathological grading standards on the efficiency of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) in the diagnosis of pancreatic cancer. MethodsRelated clinical data and pancreatic cytopathological results were collected from 256 patients with pancreatic space-occupying lesions who underwent EUS-FNA in The First Affiliated Hospital of Anhui Medical University from May 2011 to March 2019, and the influencing factors for the diagnostic efficiency of EUS-FNA were analyzed based on surgical pathology and follow-up results. The independent samples t-test or the Mann-Whitney U test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups. The receiver operating characteristic (ROC) curve was used to evaluate the value of different cytopathological grading standards in the diagnosis of pancreatic cancer. ResultsA total of 67 patients who were lost to follow-up were excluded, and a total of 189 patients were included in the study. According to the Papanicolaou cytopathological standard, there were 47 cases of heterotypic cells, 25 cases of suspected cancer cells, 20 cases of cancer cells, and 97 cases without tumor cells based on EUS-FNA. A total of 133 patients were confirmed to have pancreatic cancer by postoperative pathology and follow-up results, among whom 52 had no tumor cells, 36 had heterotypic cells, 25 had suspected cancer cells, and 20 had cancer cells based on cytopathological results. EUS-FNA had a true positive rate of 6090% (81 patients) and a false negative rate of 39.10% (52 patients) in the diagnosis of pancreatic cancer; for the 56 patients without pancreatic cancer, EUS-FNA had a false positive rate of 19.64% (11 patients) and a true negative rate of 80.36% (45 patients). EUS-FNA had an area under the ROC curve of 0.643 (95% confidence interval: 0.561-0.724) in the diagnosis of pancreatic cancer. In combination with different cytopathological grading standards and with the diagnostic criteria of “the identification of heterotypic cells or suspected cancer cells or cancer cells was considered positive”, “the identification of suspected cancer cells or cancer cells was considered positive”, and “the identification of cancer cells was considered positive”, the results showed that the diagnostic criteria of “the identification of heterotypic cells or suspected cancer cells or cancer cells was considered positive” improved the efficiency of EUS-FNA in the diagnosis of pancreatic cancer, with a sensitivity of 50.38% and a specificity of 75.00%. Among the 189 patients, 13 (6.88%) experienced complications after EUS-FNA, which included hyperamylasemia and abdominal pain. ConclusionThe combination of different cytopathological grading standards can help improve the efficiency of EUS-FNA in the diagnosis of pancreatic cancer.

Objective To investigate the endoscopic ultrasound (EUS) features of distal biliary stricture (DBS), and to provide a clinical basis for the evaluation of DBS by EUS. Methods Related clinical data were collected from 175 patients with DBS who underwent EUS examination in The First Affiliated Hospital of Anhui Medical University from April 2016 to March 2020 to analyze their clinical manifestation, laboratory examination results, imaging findings, and EUS findings, and the patients were followed up to summarize the EUS features of DBS. The chi-square test was used for comparison of categorical data between groups, and the t -test was used for comparison of continuous data between groups. Results Among the 175 patients with DBS, 85(48.57%) had benign DBS and 90(51.43%) had malignant DBS. Compared with the patients with benign DBS, the patients with malignant DBS had a significantly longer length of stricture on EUS (14.1±3.0 mm vs 7.9±3.0 mm, t =13.358, P < 0.001) and significantly higher incidence rates of the characteristic changes on EUS such as hypoechoic space-occupying lesions in lumen (57.8% vs 34.1%, χ 2 =9.843, P =0.002), peripheral lymph node enlargement (26.7% vs 12.9%, χ 2 =5.147, P =0.023), and pancreatic duct dilatation (51.1% vs 28.2%, χ 2 =9.532, P =0.002). EUS combined with magnetic resonance cholangiopancreatography had a sensitivity of 70.6% in the diagnosis of benign DBS and a sensitivity of 92.2% in the diagnosis of malignant DBS. Conclusion The characteristic EUS features of DBS, such as long length of stricture, hypoechoic lesion, peripheral lymph node enlargement, and pancreatic duct dilatation, may help with the differential diagnosis of DBS in clinical practice.
