Blastocystis is a common unicellular intestinal protozoa in humans and animals, and the most common clinical manifestations of infections include abdominal pain and diarrhea. Based on the sequence of the small-subunit ribosomal RNA (SSU rRNA) gene, 28 subtypes of B. hominis (ST1 to ST17, ST21 and ST23 to ST32) have been characterized. Previous studies have demonstrated that B. hominis infection is strongly associated with inflammatory bowel disease (IBD), irritable bowel syndrome (IBS) and other intestinal diseases, which threatens the health and quality of life among patients with B. hominis infection and is considered as an important public health problem. This review summarizes the progress of researches on B. hominis infection among IBD and IBS patients during the past 20 years, so as to provide insights into management of blastocystosis in China.

Objective: To clarify the values of autotaxin (ATX) in patients with primary biliary cholangitis (PBC) and PBC-related hepatocellular carcinoma (HCC). Methods: 179 patients with PBC were selected from prospective cohorts of autoimmune liver diseases at the time of first diagnosis of PBC in Department of Hepatology, the Fifth Medical Center of PLA General Hospital, from January 2016 to January 2018, all patients with PBC received UDCA therapy, primary endpoint was event of HCC, the follow-up period was censored at the date of HCC. The relationship between level of ATX and clinical features in patients with PBC and its potential value in predicting disease progression and PBC-related HCC were analyzed. Results: The ATX level in the peripheral blood of patients with PBC was significantly higher than that of alcoholic liver cirrhosis(ALC) (t = 3.278, P = 0.001) and healthy controls(HC) (t = 6.594, P < 0.001), however, when comparing PBC to non-PBC related HCC, no significant difference was found between the groups(t=-0.240, P = 0.811). Consistent with peripheral blood levels, histochemical staining indicated that ATX in the liver of patients with PBC was significantly higher than that of HC (Z=-3.633, P < 0.001) and ALC (Z=-3.283, P < 0.001), and the expression of ATX in PBC with advanced histological stage was significantly higher than PBC with early stage (Z=-2.018, P = 0.034). The baseline ATX level in PBC patients without developing to HCC during follow-up had significant difference to patients with developing to HCC (228.451 ± 124.093 ng/ml vs 301.583 ± 100.512 ng/ml, t = 2.339, P = 0.021). The result in multivariate logistic regression analysis showed that ATX were independent predictors of PBC related HCC(OR 1.245, 95%CI 1.097-1.413). The optimal critical value of peripheral blood ATX level at baseline for predicting HCC was 235.254 ng/ml, with the cut-off value of 0.714 in AUC of the ROC (95% CI was 0.597~ 0.857), sensitivity and specificity were 84.6% and 59.0%, respectively. Conclusion: ATX level was significantly higher in PBC patients over controls, and it's concentration was correlated with UDCA efficacy and fibrosis stage. ATX has potential values in predicting disease progression and PBC-related HCC.

Background: For anatomic total arthroscopic repair, cementless humeral fixation has recently gained popularity. However, few studies have compared clinical, radiographic, and patient-reported outcomes between cemented and press-fit humeral fixation, and none have performed follow-up for longer than 5 years. In this study, we compared long-term postoperative outcomes in patients receiving a cemented versus press-fit humeral stem anatomic arthroscopic repair. Methods: This study retrospectively analyzed 169 shoulders that required primary anatomic total shoulder arthroplasty (aTSA). Shoulders were stratified by humeral stem fixation technique: cementation or press-fit. Data were collected pre- and postoperatively. Primary outcome measures included range of motion, patient reported outcomes, and radiographic measures. Results: One hundred thirty-eight cemented humeral stems and 31 press-fit stems were included. Significant improvements in range of motion were seen in all aTSA patients with no significant differences between final cemented and press-fit stems (forward elevation: P=0.12, external rotation: P=0.60, and internal rotation: P=0.77). Patient reported outcome metrics also exhibited sustained improvement through final follow-up. However, at final follow-up, the press-fit stem cohort had significantly better overall scores when compared to the cemented cohort (visual analog score: P=0.04, American Shoulder and Elbow Surgeon Score: P<0.01, Simple Shoulder Test score: P=0.03). Humeral radiolucency was noted in two cemented implants and one press-fit implant. No significant differences in implant survival were observed between the two cohorts (P=0.75). Conclusions In this series, we found that irrespective of humeral fixation technique, aTSA significantly improves shoulder function. However, within this cohort, press-fit stems provided significantly better outcomes than cemented stems in terms of patient reported outcome scores.Level of evidence: III.

Methods: Among the patients who underwent TSA, 119 shoulders were retrospectively analyzed. Preoperative and postoperative clinical outcome data were collected. Linear regression analysis (univariate and multivariate) was conducted to evaluate the associations of clinical outcomes with age. Kaplan-Meier curves and Cox regression analyses were performed to evaluate implant survival. Results: At final follow-up, patients of all ages undergoing aTSA experienced significant and sustained improvements in all primary outcome measures compared with preoperative values. Based on multivariate analysis, age at the time of surgery was a significant predictor of postoperative outcomes. Excellent implant survival was observed over the course of this study, and Cox regression survival analysis indicated age and sex to not be associated with an increased risk of implant failure. Conclusions When controlling for sex and follow-up duration, older age was associated with significantly better patient-reported outcome measures. Despite this difference, we noted no significant effects on range of motion or implant survival.Level of evidence: IV.

Objective: To investigate the clinicopathological features, immunophenotype, and genetic alterations of rectal adenocarcinoma with enteroblastic differentiation. Methods: Four cases of rectal adenocarcinoma with enteroblastic differentiation were collected at the Affiliated Hospital of Qingdao University, Qingdao, China (three cases) and Yantai Yeda Hospital of Shandong Province, China (one case) from January to December 2022. Their clinical features were summarized. Hematoxylin and eosin stain and immunohistochemical stain were performed, while next-generation sequencing was performed to reveal the genetic alterations of these cases. Results: All four patients were male with a median age of 65.5 years. The clinical manifestations were changes of stool characteristics, bloody stools and weight loss. All cases showed mixed morphology composed of conventional adenocarcinoma and adenocarcinoma with enteroblastic differentiation. Most of the tumors consisted of glands with tubular and cribriform features. In one case, almost all tumor cells were arranged in papillary structures. The tumor cells with enteroblastic differentiation were columnar, with relatively distinct cell boundaries and characteristic abundant clear cytoplasm, forming fetal gut-like glands. Immunohistochemically, the tumor cells were positive for SALL4 (4/4), Glypican-3 (3/4) and AFP (1/4, focally positive), while p53 stain showed mutated type in 2 cases. The next-generation sequencing revealed that 2 cases had TP53 gene mutation and 1 case had KRAS gene mutation. Conclusions: Rectal adenocarcinoma with enteroblastic differentiation is rare. It shows embryonal differentiation in morphology and immunohistochemistry, and should be distinguished from conventional colorectal adenocarcinoma.
