Background Transscleral diode laser cyclophotocoagulation (TDCP) was used to later stage of glaucoma in the past.However,the indications of TDCP are expanding gradually over time and there are more and more reports about its application in different stages and different types of glaucoma.Objective This study was to compare the clinical efficacy of TDCP and trabeculectomy for primary acute angle-closure glaucoma (PAACG) with persistent ocular hypertension.Methods Ninety-five PAACG patients with persistent ocular hypertension were retrospectively analyzed.The patients were divided into TDGP group (62 eyes of 56 cases) and trabeculectomy group (44 eyes of 39 cases) based on the difference of treating fashions.The clinical outcomes were compared between the two groups with the evaluating indexes of visual acuity,intraocular pressure (IOP) before and 1 week,3 months and the end of following-up as well as the number of drug used and the re-treatment.Results The demography was matched between the two groups (all at P＞0.05).The number of eyes with visual improvement was significantly different among the groups (x2 =30.927,P =0.002) in the TDCP group.Compared with before treatment,the number of visual improvement in 1 week after treatment was significantly raised (x2 =16.778,P =0.002).No significant differences were seen in the eye number of visual improvement in various timepoints after treatment (all at P＞0.008).Also,the eye number of visual improvement was significantly different among the different timepoints (x2 =44.345,P＜0.001),and statistically significant change was found between the preoperation and postoperative 1 week (x2 =23.725,P＜0.001).However,there were no significant differences in the eye number of visual improvement in various timepoints after operation each other (all at P＞0.008).The IOP was insignificantly altered among the groups at various timepoints (Fgroup =3.836,P =0.053),but the change was significantly different over time (Ftime =757.078,P＜0.001).The postoperative IOP was significantly higher than that of preoperation in both groups (all at P＜0.001).The proportion of eyes using lowering-IOP drugs was 48.4％ in the TDCP group,and that in the trabeculectomy group was 27.3％,showing a significant difference between them (x2 =4.796,P =0.029).The retherapy was performed in 20 eyes (32.3％) and 2 eyes (4.5％) in the TDCP group and the trabeculectomy group,respectively.Conclusions The short-term lowing-IOP effecacy of TDCP is similar to trabeculectomy,but the longterm lowing-IOP efficacy of TDCP is not good.Compared with the trabeculectomy,TDCP shows more simple operation,less time-consuming during the surgery and milder tissue damage,but the eyes continuing to use anti-glaucomatous drugs or re-therapy are increased.

Objective: To explore the potential mechanism of acupuncture and moxibustion in treating Crohn disease (CD) by evaluating the changes in histamine and inflammatory factors in the skin tissue at Tianshu (ST25) of rats.Methods: Fifty-eight Sprague-Dawley rats were randomly divided into a normal group (n=14) and a CD-modeling group (n=44). Rats in the CD-modeling group received enema with 2,4,6-trinitrobenzene sulfonic acid plus ethanol to establish CD models. The enema was repeated once every 7 d for a total of 4 times. After modeling, four modeled rats and four normal rats were randomly selected for model identification. After the CD model was successfully established, the remaining rats in the CD-modeling group were randomly divided into a model group, an acupuncture group, a moxibustion group, and a Western medication group, with ten rats in each group. The rats in the acupuncture and moxibustion groups were treated with acupuncture or moxibustion at Tianshu (ST25) and Shangjuxu (ST37); the rats in the Western medication group were treated with mesalazine enteric-coated tablets by gavage for continuous 7 d. After the intervention, the colon tissue of rats in each group was collected. After gross observation, hematoxylin-eosin (HE) staining was performed to further observe the pathological changes. The expression of histamine in the skin tissue at Tianshu (ST25) was detected by enzyme-linked immunosorbent assay. The expression of tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-18, IL-10, and IL-6 in the skin tissue at Tianshu (ST25) was detected by Western blotting. Results: Compared with the normal group, the colonic wall of rats in the model group showed cobblestone-like changes, local ulcers, and polyps in dark red and thickening and hardening. HE staining showed local loss of mucosal epithelial layer and formation of slit-like ulcers, destruction of mucosal glands, edema, and infiltration of inflammatory cells in lamina propria and submucosa, and occasional formation of sarcoid-like granuloma. The levels of histamine and IL-6 were significantly up-regulated (P<0.01, P<0.05), and the levels of TNF-α, IL-18, and IL-10 were significantly down- regulated (P<0.01 or P<0.05) in the skin tissue at Tianshu (ST25) of rats in the model group. Compared with the model group, the pathomorphological damage of the colon tissue of rats in the acupuncture group, moxibustion group, and Western medication group was significantly improved. The levels of histamine and IL-6 were significantly down- regulated (P<0.01, P<0.05), and the level of IL-10 was significantly up-regulated (P<0.01) in the skin at Tianshu (ST25) of rats in the acupuncture group. The levels of histamine and IL-6 were significantly down-regulated (P<0.01, P<0.05), and the levels of TNF-α, IL-18, and IL-10 were significantly up-regulated (P<0.01 or P<0.05) in the skin tissue at Tianshu (ST25) of rats in the moxibustion group. The level of histamine was significantly down-regulated (P<0.01), and the levels of IL-18 and IL-10 were significantly up-regulated (P<0.05, P<0.01) in the skin tissue of rats in the Western medication group. Compared with the acupuncture group, the level of IL-10 in the skin tissue at Tianshu (ST25) of rats in the moxibustion group was significantly up-regulated (P<0.01). Conclusion: The inflammatory responses in the skin tissue at Tianshu (ST25) may be the external manifestation of CD. Significant differences in the regulation of inflammatory responses in the skin tissue at Tianshu (ST25) between acupuncture and moxibustion exist, which may be caused by the differences in the stimulation characteristics between acupuncture and moxibustion.

Objective Analyze and compare the therapeutic value of contrast-enhanced ultrasound (CEUS) and enhanced spiral CT in patients with primary hepatocellular carcinoma (PHC) undergoing transcatheter arterial chemoembolization (TACE). Methods A retrospective analysis was conducted on 108 PHC patients (122 lesions) treated at Beijing Shijitan Hospital affiliated with Capital Medical University from July 2021 to June 2023. All patients were treated with TACE. After treatment, CEUS and contrast-enhanced spiral CT examinations were performed to evaluate the inactivation status of tumor lesions, with pathological results as the gold standard. The receiver operating characteristic curve and decision tree model were used to comprehensively evaluate the diagnostic value of CEUS, contrast-enhanced spiral CT, and their combination in PHC. Results The pathological results showed that 79 lesions remained active (positive) and 43 lesions were completely inactivated (negative). The areas under the receiver operating characteristic curve for evaluating PHC treatment efficacy by CEUS, contrast-enhanced spiral CT, and their combination were 0.975, 0.918, and 0.994, respectively. The sensitivity, positive predictive value, and actual application accuracy of CEUS and the combined method were higher than those of contrast-enhanced spiral CT (P < 0.05). A decision tree diagnostic model for PHC treatment efficacy was constructed using CEUS, contrast-enhanced spiral CT, and their combination as independent variables and PHC treatment efficacy as the dependent variable. The misjudgment rates were 3.3%, 10.7%, and 0.8%, respectively, and the prediction accuracy was 96.7%, 89.3%, and 99.2%, respectively. Conclusions CEUS and the combination of CEUS and contrast-enhanced spiral CT have high evaluation value for PHC treatment efficiency.
