Inguinal hernia is the most prevalent type of abdominal wall hernia. Indirect inguinal hernia is twice as common as direct inguinal hernia. Computed tomography and magnetic resonance imaging can be used to evaluate inguinal hernia, but these modalities are greatly limited by their cost and availability. Ultrasonography has emerged as the most convenient imaging tool for diagnosing inguinal hernia due to its advantages, such as portability and absence of radiation. The present pictorial review presents an overview on the use of ultrasonography in the evaluation of inguinal hernia with a particular emphasis on the regional anatomy, relevant scanning tips, identification of subtypes, postoperative follow-up, and diagnosis of pathologies mimicking inguinal hernia.

Objective To observe the clinical efficacy of self-prescribed Guchong Decoction combined with Ferroids for the treatment of iron deficiency anemia (IDA)patients with unconsolidation of thoroughfare and conception vessels. Methods A total of 70 IDA patients with unconsolidation of thoroughfare and conception vessels were randomized into treatment group and control group,35 cases in each group. The control group was given oral use of Ferroids, and the treatment group was treated with self-prescribed Guchong Decoction combined with Ferroids. One month constituted a treatment course,and both groups were treated for 2 courses. Before and after treatment,we compared the parameters of blood routine test for red blood cells(RBC),hemoglobin (HGB), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), MCH concentration (MCHC),white blood cells(WBC)and platelets,as well as reticulocytes(Ret)and iron metabolism indexes including serum iron(SI),serum ferritin(SF),and total iron-binding capacity(TIBC). The adverse reaction was monitored during the treatment. After treatment,both western medicine clinical efficacy and traditional Chinese medicine (TCM)syndrome clinical efficacy of the two groups were evaluated. A 3-month follow-up was carried out after treatment to evaluate the recurrence rate. Results(1)Drop-out occurred in one case from the treatment group and in 2 cases from the control group because of short-term medication suspension.(2)After treatment for 2 months, western medicine clinical cure rate of the treatment group was 82.4％ and that of the control group was 60.6％, and TCM syndrome clinical cure rate of the treatment group was 94.1％ and that of the control group was 51.5％,the difference being significant(P < 0.05 or P < 0.01).(3)The levels of RBC,HGB,Ret, MCV, MCH, MCHC, and WBC of the two groups were obviously increased after treatment (P < 0.01), and PLT level was markedly decreased (P < 0.01)as compared with those before treatment,but the inter-group differences after treatment were insignificant (P > 0.05). (4)After treatment,iron metabolism indexes of SF and SI of the two groups were significantly increased (P < 0.01), and TIBC of the treatment group was significantly decreased (P < 0.01). The treatment group had stronger effect on increasing SF and SI and on decreasing TIBC than the control group (P < 0.05 or P < 0.01). (5)The incidence of adverse reaction and the recurrence rate in the treatment group were lower than those of the control group,the difference being significant (P< 0.01). Conclusion Guchong Decoction combined with Ferroids is effective for the treatment of IDA with unconsolidation of thoroughfare and conception vessels through relieving symptoms rapidly, reducing gastrointestinal adverse reaction,and decreasing recurrent rate.

Diagnosis of spontaneous coronary artery dissection (SCAD) is challenging because of its rarity and uncertain etiology. It frequently occurs in young women during pregnancy and in the postpartum period, and rarely found in elder women with no history of cardiovascular disease or coronary risk factors. In this article we report a case of SCAD in a 75-year-old woman without traditional cardiovascular risk factors who presented with syncope and mild chest discomfort. There were no abnormal electrocardiographic changes and no elevated cardiac enzymes were detected. Computed tomography of brain revealed nothing abnormal. Coronary artery disease was suspected. Coronary angiogram revealed dissection in the middle left circumflex artery. The patient underwent percutaneous transluminal coronary angioplasty and was free of symptoms at 6-month follow-up. Our report suggests that emergency coronary angiography is indicated if syncope caused by coronary artery disease is suspected.

OBJECTIVETo investigate the effects of sphingosine-1-phosphate (S1P) on cyclophosphamid (CTX) and cisplatin (DDP)-induced ovarian damage and on the efficacy of chemotherapy in mice bearing S180 murine sarcoma.

METHODSFifty-two female C57BL/6 mice were randomized into normal control group (n=10), tumor-bearing model group (n=14), CTX+DDP group (n=14), and S1P+CTX+DDP group (n=14). Before medication and on day 11 of medication during diestrus stage, the mice were sacrificed to measure the ovarian weight, numbers of primordial follicles and growing follicles, tumor weight, and serum levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH) and estradiol ( E2).

RESULTSAt day 11 of medication, the levels of serum FSH and E2, but not LH, showed significant differences in CTX+DDP group from those in the other groups (P<0.01). FSH, E2, and LH levels were comparable between S1P+CTX+DDP group and the control group (P>0.05). The number of primodial follicles and weight of ovaries in CTX+DDP group decreased significantly compared to those in the other groups (P<0.01). The number of growing follicles in CTX+DDP group was significantly lower than that in the control and model groups(P<0.01), but similar to that in S1P group (P>0.05). The number of primodial follicles and growing follicles and ovarian weight in S1P+CTX+DDP group were close to those in the control and model groups (P>0.05). In CTX+DDP and S1P+CTX+DDP groups, the tumor weight were significantly lower than that in the other two groups (P<0.01), and the tumor inhibition rates were both higher than 60%.

CONCLUSIONS1P can ameliorate chemotherapy-induced ovarian damage in mice without affecting the efficacy of chemotherapy.

Purpose: Plasmablastic lymphoma (PBL) is a rare, aggressive lymphoma that is characterized by terminal B-cell differ‑ entiation. In the West, PBL usually occurs in patients with immunodeficiencies, particularly those induced by human immunodeficiency virus (HIV) infection. We investigated the clinicopathological features of PBL at a single institute in Taiwan, where HIV infection is rare. Methods: This retrospective chart review identified PBL cases that were treated at a single institute in southern Tai‑ wan between 2008 and 2024. Results: We identified nine patients (four males and five females; median age 71 years). Of the eight patients tested for HIV, only one tested positive. Pathologically, the tumors showed plasmablastic morphology and immunopheno‑ type, and three (33%) cases tested positive for Epstein–Barr virus. Six (67%) patients presented with Stage IV disease, including five (56%) with malignant effusion. Six patients were treated with chemotherapy and the remaining three received only supportive care. During a median follow-up of 10 months, five patients died of progressive disease, two died of unrelated diseases, and two were alive with PBL relapse. Conclusion In Taiwan, PBL constitutes a rare and aggressive clinical condition and is frequently associated with malignant effusion. In contrast to Western patients, the PBL in most patients from Taiwan was unrelated to HIV infection.

BACKGROUNDLong-term maintenance of sinus rhythm after successful conversion of chronic atrial fibrillation (CAF), often ameliorates patients' symptoms, reduces the risk of ischemic stroke and improves cardiovascular hemodynamics. This prospective study aims to evaluate the long-term efficacy and safety of very low-dose amiodarone (100 mg daily) for the maintenance of sinus rhythm after successful direct-current (DC) cardioversion in patients with CAF and rheumatic heart disease (RHD) post intervention.

METHODSThis study was a randomized prospective trial. One day after successful DC cardioversion (remained normal sinus rhythm) in patients with CAF and RHD post intervention for more than six months and adequate anticoagulation, all were randomly administered either amiodarone 200 mg daily in group A or amiodarone 100 mg daily in group B.

RESULTSA total of 76 patients (40 men and 36 women) were examined from February 1998 to December 1999. The mean age of the patients was (66 +/- 10) years, and the mean follow-up was (67 +/- 8) months (range 61 to 84 months). Actuarial rates of the maintenance of sinus rhythm were similar in the two groups after 5 years of follow-up. Four patients (11%) in group A but none in group B experienced significant adverse effects that necessitated withdrawal of amiodarone. No death occurred during the study period.

CONCLUSIONA very low dose of amiodarone results in adequate long-term efficacy and is safe for maintaining sinus rhythm in patients with CAF and RHD post intervention after successful DC cardioversion.

Arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) is predominantly an inherited cardiomyopathy with typical histopathological characteristics of fibro-fatty infiltration mainly involving the right ventricular (RV) inflow tract, RV outflow tract, and RV apex in the majority of patients. The above pathologic evolution frequently brings patients with ARVD/C to medical attention owing to the manifestation of syncope, sudden cardiac death (SCD), ventricular arrhythmogenesis, or heart failure. To prevent future or recurrent SCD, an implantable cardiac defibrillator (ICD) is highly desirable in patients with ARVD/C who had experienced unexplained syncope, hemodynamically intolerable ventricular tachycardia (VT), ventricular fibrillation, and/or aborted SCD. Notably, the management of frequent ventricular tachyarrhythmias in ARVD/C is challenging, and the use of antiarrhythmic drugs could be unsatisfactory or limited by the unfavorable side effects. Therefore, radiofrequency catheter ablation (RFCA) has been implemented to treat the drug-refractory VT in ARVD/C for decades. However, the initial understanding of the link between fibro-fatty pathogenesis and ventricular arrhythmogenesis in ARVD/C is scarce, the efficacy and prognosis of endocardial RFCA alone were limited and disappointing. The electrophysiologists had broken through this frontier after better illustration of epicardial substrates and broadly application of epicardial approaches in ARVD/C. In recent works of literature, the application of epicardial ablation also successfully results in higher procedural success and decreases VT recurrences in patients with ARVD/C who are refractory to the endocardial approach during long-term follow-up. In this article, we review the important evolution on the delineation of arrhythmogenic substrates, ablation strategies, and ablation outcome of VT in patients with ARVD/C.
