Abstract
OBJECTIVE To study the efficacy of transarterial chemoembolization (TACE) combined with high-intensity focused ultrasound (HIFU) in patients with middle-advanced liver cancer. PATIENTS AND METHODS A total of 100 patients with middle-advanced liver cancer treated in our hospital from January 2015 to January 2018 were selected and randomly divided into TACE group (control group, n=50) and TACE combined with HIFU group (experimental group, n=50) according to different therapeutic regimens. The efficacy was observed after the operation, the blood was collected to detect the postoperative liver function indexes aspartate aminotransferase (AST) and alanine aminotransferase (ALT), the postoperative complications were observed. Also, the immune indexes cluster of differentiation 3+ (CD3+), CD4+, and CD8+ were determined. Moreover, the quality of life (QOL) score was compared between the two groups, the 1-, 2-, 3-, and 5-year survival rates were observed after the operation. Also, the changes in the levels of tumor markers α-L-fucosidase (AFU), alpha-fetoprotein (AFP), carbohydrate antigen 19-9 (CA19-9), and carcinoembryonic antigen (CEA) were observed. RESULTS In experimental group, the levels of AST, ALT, and blood urea nitrogen (BUN) after the operation were significantly decreased (p<0.05), while the postoperative efficacy was significantly superior to that in control group (p<0.05). The incidence of postoperative complications was significantly reduced (p<0.05), the levels of CD3+, CD4+, CD8+, and natural killer (NK) cells were markedly increased (p<0.05). Also, the QOL score was evidently better than that in control group (p<0.05) and the 1-, 2-, 3-, and 5- year survival rates after the operation were evidently higher than those in control group (p<0.05). After treatment, the levels of AFU, AFP, CA19-9, and CEA were remarkably lower than those before treatment in both groups, while they were remarkably lower in experimental group than those in control group (p<0.05). CONCLUSIONS TACE combined with HIFU in the treatment of patients with middle-advanced liver cancer can restore the hepatic metabolism, enhance the immunity, improve the QOL, prolong the survival time of patients, and significantly reduce the tumor markers. Also, it has fewer adverse reactions and definite overall efficacy, which is worthy of popularization and application.

Abstract
This meta-analysis compared the efficacy and safety of the contact force (CF)-sensing catheter and second-generation cryoballoon (CB) ablation for treating atrial fibrillation (AF). Six controlled clinical trials comparing ablation for AF using a CF-sensing catheter or second-generation CB were identified from PubMed, EMBASE, Cochrane Library, Wanfang Data, and China National Knowledge Infrastructure. The procedure duration was significantly lower in the CB group compared with that in the CF group [mean difference (MD)=29.4; 95%CI=17.84–40.96; P=0.01], whereas there was no difference between the groups for fluoroscopy duration (MD=0.59; 95%CI=–4.48–5.66; P=0.82). Moreover, there was no difference in the incidence of non-lethal complications (embolic event, tamponade, femoral/subclavian hematoma, arteriovenous fistula, pulmonary vein stenosis, phrenic nerve palsy, and esophageal injury) between the CB and the CF groups (8.38 vs 5.35%; RR=0.66; 95%CI=0.37–1.17; P=0.15). Transient phrenic nerve palsy occurred in 17 of 326 patients (5.2%) of the CB group vs none in the CF group (RR=0.12; 95%CI=0.03–0.43; P=0.001). A comparable proportion of patients in CF and CB groups suffered from AF recurrence during the 12-month follow-up after a single ablation procedure [risk ratio (RR)=1.03; 95%CI=0.78–1.35; P=0.84]. AF ablation using CF-sensing catheters and second-generation CB showed comparable fluoroscopy duration and efficacy (during a 12-month follow-up), with shorter procedure duration and different complications in the CB group.

Abstract
Sclerosing stromal tumor (SST) is a rare ovarian neoplasia deriving from the sex cord stromal tumor, which occurs usually in the sec- ond and third decades of life. However, the authors report a 46-year old multiparous woman who presented with a cystic-solid left pelvic mass, a large amount of ascites, and elevated serum CA-125, all suggesting a malignant tumor. Surgery was performed and final histopathological diagnosis of the specimen was diagnosed with SST. The authors herein report an extremely rare case of SST with a cystic-solid pelvic mass and a large amount of ascites, which is useful to demonstrate the possibility of SST in multiparous woman.

Abstract
BACKGROUND Hirschsprung's disease (HSCR) is one of the common digestive disorders in the new born. Long non-coding RNAs (lncRNAs) play an important role in various biological processes. However, knowledge on lncRNAs in HSCR is limited. METHODS The expression profile of lncRNAs in HSCR was obtained using microarray. A total of 2078 differentially expressed lncRNAs were detected by microarray in HSCR tissues compared with matched normal colon tissues (fold change ≥2, p < 0.05). Candidate biomarkers were selected from these differentially expressed lncRNAs based on artificial criterion (raw signal intensity ≥50; fold change ≥8) and then validated in 80 pairs of HSCR and normal tissues using quantitative real-time polymerase chain reaction (qRT-PCR). Moreover, the computational analysis was used to evaluate the lncRNA-microRNA and lncRNA-protein relationships. KEY RESULTS A panel of 5-lncRNAs was identified to distinguish HSCR from normal tissues with remarkable sensitivity and specificity. The area under the receiver operating characteristic curve (AUC) for HSCR identification in the validation set was 0.875. The bioinformatics analysis reveals that these dysregulated lncRNAs are mainly involved in RNA-protein relationships, including RNA splicing, binding, transport, processing, and localization. CONCLUSIONS & INFERENCES Our results are the first to report the expression profile of dysregulated lncRNAs in HSCR and infer that lncRNAs may serve as novel diagnostic biomarkers for HSCR.

Abstract
Deep infiltrating endometriosis (DIE) is a complex disorder that affects 6% to 12% of all women in the reproductive age. In these cases, treatment is more difficult with possible incomplete pain relief and a considerable possibility of recurrence. Here, the authors report a case of a 41-year-old woman with a history of severe dysmenorrhea, dyspareunia, and chronic pelvic pain because of deep infiltrating pelvic and peritoneal endometriosis, who underwent segmental colorectal resection three years ago for large bowel obstruction due to colonic endometriosis. To ensure complete removal of the disease, the authors injected gonadotropin-releasing hormone agonist (GnRHa) in three periodic cycles before laparoscopic surgery. We performed laparoscopic hysterectomy and deep pelvic nodule resection and pelvic adhesion releasing. After five days of hospitalization, the patient recovered totally and was not experiencing any pain at three months' follow-up. Laparoscopic treatment has more become the standard of treatment for DIE. A review of the literature regarding pathology and physiology of DIE and surgical aspects of its management is undertaken. The authors would like to renew the current laparoscopic surgery in curing the DIE, as they believe that this is also a useful addition to the literature.

Abstract
BACKGROUND Chronic sinusitis (CRS) is a common otorhinolaryngologic disease that is frequently encountered in everyday practice, but there is a lack of precise data regarding the prevalence of CRS in developing countries. We performed a national investigation in China to determine the prevalence and associated factors of CRS. METHODS We conducted a cross-sectional investigation in 2012. A stratified four-stage sampling method was used to select participants randomly from seven cities in mainland China. All participants were interviewed face-to-face via a standardized questionnaire. Unconditional logistic regression analyses were conducted to examine the association between smoking and sinusitis after adjusting for socio-demographic factors. RESULTS This study included a total of 10 636 respondents from seven cities. The overall prevalence of CRS was 8.0% and ranged from 4.8% to 9.7% in seven centres. Chronic sinusitis affected approximately 107 million people in mainland China. Chronic sinusitis was particularly prevalent among people with specific medical conditions, including allergic rhinitis, asthma, chronic obstructive pulmonary disease and gout. The prevalence was slightly higher among males (8.79%) than females (7.28%) (P = 0.004), and the prevalence varied by age group, ethnicity and marital status and education (P < 0.05), but not by household per capita income or living space (P > 0.05). Both second-hand tobacco smoke and active smoking were independent risk factors for CRS (P = 0.001). CONCLUSIONS Chronic sinusitis is an important public health problem in China. Our study provides important information for the assessment of the economic burden of CRS and the development and promotion of public health policies associated with CRS particularly in developing countries.

Abstract
OBJECTIVE To investigate the ocular phenotype and gene mutation of a Chinese pedigree with familial amyloid polyneuropathy (FAP) and vitreous amyloidosis. METHODS A Chinese pedigree with familial amyloid polyneuropathy and vitreous amyloidosis was recruited. Combined phacoemulsification, vitrectomy and intraocular lens implantation were performed on the right eye of the index patient. Ophthalmic investigations were performed before and after surgery. The DNA from the pedigree was sequenced for the transthyretin (TTR) gene. RESULTS After vitrectomy, the best-corrected visual acuity of the patient improved from counting finger to 20/20. Red-free confocal ophthalmoscopy demonstrated perifoveal ring and several perivessel white sheaths. Optical coherence tomography (OCT) revealed cotton wool like reflections on the vitreoretinal interface. Electroretinogram and autofluorescence was normal. Amyloid was present in the vitreous specimen. A substitution of T to G at nucleotide 381 in exon 4 of TTR DNA (Ile107Met) was found. This mutation co-segregated with phenotype in the pedigree and was not detected in 200 controls. CONCLUSIONS TTR Ile107Met mutation is associated with vitreous amyloidosis and FAP. OCT and red-free imaging are helpful in identifying amyloid deposits in the retina.

Abstract
OBJECTIVE To assess hepatic iron deposition quantitatively in patients with chronic hepatitis B (HBV) infection, using abdominal susceptibility-weighted magnetic resonance imaging (SWI). METHODS Patients with HBV infection and healthy controls underwent abdominal SWI and were assessed for serum iron markers. Phase values were measured and five grades of hepatic iron deposition were described by SWI. RESULTS Patients with HBV infection (n = 327) and healthy controls (n = 50) were prospectively enrolled. In total, 77 (25.4%) patients with HBV infection had hepatic iron deposition as determined by SWI. Phase values were significantly different between patients with hepatic iron deposition compared with patients without hepatic iron deposition or controls, and were significantly different across different grades of hepatic iron deposition. Serum iron, ferritin, transferrin and transferrin saturation were significantly higher in patients with, versus those without, hepatic iron deposition. Only serum ferritin was significantly different across different grades of hepatic iron deposition, and there was a low inverse correlation between serum ferritin and phase values. CONCLUSIONS Compared with serum iron markers, abdominal SWI may represent a powerful tool to assess hepatic iron deposition quantitatively in patients with chronic HBV infection.

Abstract
Sarcoidosis is a non-caseous granulomatous disease which could involve numerous organs including lungs, eyes, skin, nervous system, heart, liver. However, the genitourinary tract involvement was rarely reported in sarcoidosis. We report the case of a 45-year-old married woman who presented with 2 months history of a vulval mass as large as a soybean, and did not reveal any remarkable pulmonary signs. Biopsy results showed non-caseous granulomatous inflammation consistent with sarcoidosis in the vulvar lesion. To our knowledge, this is the first reported case of this entity in the world. Based on the related literature, we highlight the possibility of gynecologic involvement in sarcoidosis.

Abstract
OBJECTIVE Varicose veins of the lower extremities is a common clinical condition. Although surgical treatment is often successful, the recurrence rate remains high. This retrospective study evaluated the reasons for postoperative recurrence of varicose veins by analysing ultrasonography and venography findings in patients with recurrent disease. METHODS A series of consecutive cases of recurrent varicose veins of the lower limbs was reviewed. Data collected included clinical characteristics, symptoms and vascular imaging. RESULTS The study included 109 legs with recurrent varicose veins (92 patients): 101/109 legs (92.7%) showed perforating vein insufficiency and 86/109 (78.9%) showed reflux of the superficial femoral vein, of varying degrees of severity. Residual saphenous vein was recorded for 82 legs (75.2%), while 19 (17.4%) had blocked iliac veins due to post-thrombotic syndrome. CONCLUSIONS Several factors that may contribute to varicose vein recurrence have been identified. These include failure to ligate perforating veins and initial failure to perform the appropriate surgical intervention. Prevention of varicose vein recurrence after surgical correction requires a more extensive use of preoperative imaging, to tailor surgical intervention to suit individual patients.

Abstract
Antititin antibody occurs in the serum of myasthenia gravis (MG) patients with thymoma (MGT), and is a diagnostic marker for the disease. The mechanism that triggers MGT development is, however, unclear. This study evaluated the role of the main immunogenic region (MIR) of titin in MGT pathogenesis. Titin MIR antiserum (antibody titre 1:16) was obtained and an in situ immunohistochemical study of thymomatous tissue samples was performed. Strong immunostaining for titin MIR was observed on epithelial cell membranes in MGT patients, and the degree of immunostaining was directly proportional to the number of epithelial cells in thymomatous tissue. Serum antititin antibody levels were closely related to titin MIR levels in thymoma cells; however, titin MIR levels did not appear to be related to MG severity. Antititin antibody may be a good surrogate marker for thymoma but is probably not involved in the pathogenesis of MGT.
