Abstract
Objective: To investigate the functional changes of key gut microbiota (GM) that produce lipopolysaccharide (LPS) in atrial fibrillation (AF) patients and to explore their potential role in the pathogenesis of AF. Methods: This was a prospective cross-sectional study. Patients with AF admitted to Beijing Chaoyang Hospital of Capital Medical University were enrolled from March 2016 to December 2018. Subjects with matched genetic backgrounds undergoing physical examination during the same period were selected as controls. Clinical baseline data and fecal samples were collected. Bacterial DNA was extracted and metagenomic sequencing was performed by using Illumina Novaseq. Based on metagenomic data, the relative abundances of KEGG Orthology (KO), enzymatic genes and species that harbored enzymatic genes were acquired. The key features were selected via the least absolute shrinkage and selection operator (LASSO) analysis. The role of GM-derived LPS biosynthetic feature in the development of AF was assessed by receiver operating characteristic (ROC) curve, partial least squares structural equation modeling (PLS-SEM) and logistic regression analysis. Results: Fifty nonvalvular AF patients (mean age: 66.0 (57.0, 71.3), 32 males(64%)) were enrolled as AF group. Fifty individuals (mean age 55.0 (50.5, 57.5), 41 males(82%)) were recruited as controls. Compared with the controls, AF patients showed a marked difference in the GM genes underlying LPS-biosynthesis, including 20 potential LPS-synthesis KO, 7 LPS-biosynthesis enzymatic genes and 89 species that were assigned as taxa harbored nine LPS-enzymatic genes. LASSO regression analysis showed that 5 KO, 3 enzymatic genes and 9 species could be selected to construct the KO, enzyme and species scoring system. Genes enriched in AF group included 2 KO (K02851 and K00972), 3 enzymatic genes (LpxH, LpxC and LpxK) and 7 species (Intestinibacter bartlettii、Ruminococcus sp. JC304、Coprococcus catus、uncultured Eubacterium sp.、Eubacterium sp. CAG:251、Anaerostipes hadrus、Dorea longicatena). ROC curve analysis revealed the predictive capacity of differential GM-derived LPS signatures to distinguish AF patients in terms of above KO, enzymatic and species scores: area under curve (AUC)=0.957, 95%CI: 0.918-0.995, AUC=0.940, 95%CI 0.889-0.991, AUC=0.972, 95%CI 0.948-0.997. PLS-SEM showed that changes in lipopolysaccharide-producing bacteria could be involved in the pathogenesis of AF. The key KO mediated 35.17% of the total effect of key bacteria on AF. After incorporating the clinical factors of AF, the KO score was positively associated with the significantly increased risk of AF (OR<0.001, 95%CI:<0.001-0.021, P<0.001). Conclusion: Microbes involved in LPS synthesis are enriched in the gut of AF patients, accompanied with up-regulated LPS synthesis function by encoding the LPS-enzymatic biosynthesis gene.

Abstract
Objective: To guide the patients with vertigo who are suitable for vestibular rehabilitation therapy (VRT), and to evaluate the curative effect through a remote guidance platform based on mobile internet. Methods: Adult outpatients, who were diagnosed as vestibular disorders and required VRT, were selected and conducted baseline evaluation and formulated vestibular rehabilitation plan according to their symptoms, diagnosis and vestibular function examination results. These patients downloaded and installed the mobile internet remote guidance platform app for VRT, and then registered and uploaded medical records. According to the VRT plan formulated by clinicians for patients, the platform launched corresponding exercise guidance videos to guide them to complete 4-week VRT exercise at home. Before and after VRT, the patients were scored with Visual Analogue Scale (VAS), Activities-specific Balance Confidence (ABC), Dizziness Handicap Inventory (DHI) and Self-rating Anxiety Scale (SAS). The rehabilitation effects were statistically analyzed by SigmaStat 4.0 software. Results: From October 2019 to October 2021, 233 patients with vertigo completed the registration of vestibular rehabilitation guidance platform, of whom 187 patients insisted on 4-week rehabilitation training and completed the scale evaluation. Among 187 patients, 65 were male and 122 were female; Age was (49.8±16.0) years; The medical history ranged from one to 192 months, with a median of eight months. Compared with that before rehabilitation exercise, the subjective feeling of vertigo in 170 patients was improved, and the overall effective rate was 90.9% (170/187). The subjective symptoms of vertigo were basically improved after rehabilitation training in patients with unilateral vestibular dysfunction, vestibular neuritis, sudden deafness with vertigo, Hunt syndrome and acoustic neuroma. There were significant differences in ABC, DHI and SAS scores before and after VRT (P<0.05). Of those patients with Meniere's disease in the intermittent period and the patients with Meniere's disease who underwent surgical treatment, more than 90% of their subjective symptoms of vertigo or dizziness improved after VRT, and there were significant differences in the scores of ABC, DHI and SAS before and after VRT exercise (P<0.05). In patients with vestibular migraine, 36.7% (11/30) had no improvement or even aggravation of subjective symptoms of vertigo after VRT, however, the DHI score after rehabilitation exercise was lower than that before exercise, and the difference was statistically significant (P<0.05). In patients with bilateral vestibular dysfunction, although most (6/8) subjective symptom scores were improved compared with those before exercise, there was no significant difference in ABC, DHI and SAS scores before and after rehabilitation (P>0.05). Conclusion: VRT with the help of vestibular rehabilitation mobile internet remote guidance platform can effectively improve the subjective symptoms of vertigo, balance ability and anxiety in patients with unilateral vestibular lesions.

Abstract
Objective: To investigate the effects of duodenal ligation on gastroesophageal reflux and bleomycin-induced pulmonary fibrosis in rats. Methods: Wistar rats were randomized into the control (Ctrl) group, bleomycin (BLM) group, duodenal ligation (GER) group and duodenal ligation plus bleomycin treatment (BLM+GER) group. At day 0 (d0), duodenum ligation was performed in the GER and the BLM+GER group through an open-abdomen surgery at 1.0 cm below the pylorus by about 30% of the circumference. Meanwhile, sham operation was performed in the Ctrl and the BLM group with similar procedures to the above without ligation of the duodenum. At day 14, bleomycin solution (5 mg/kg, for the BLM and BLM+GER groups) or saline (for the Ctrl and GER groups) was intratracheally instilled. Rats were sacrificed at d28 or at d42. HE, Masson's trichrome or TUNEL staining was performed on lung sections of the groups. The levels of hyrdoxyproline (HYP) or malondialdehyde (MDA) were measured respectively by alkaline hydrolysis or thiobarbituric acid colorimetry. The levels of pepsin and cytokines in bronchoalveolar lavage fluid (BALF) samples were assessed by ELISA. Western blot or RT-PCR was used to quantify relative lung expression of proteins or mRNA, respectively. Results: Lungs of the GER group rats were presented with mild inflammatory cell infiltration. Alveolitis and lung fibrosis was prominent in the BLM group but even more severe in the BLM+GER group. Of the Ctrl, GER, BLM and BLM+GER group, the average numbers of apoptotic cells per each magnified field (×200) on d28 lung sections was (5.6±3.0), (6.4±5.3), (15.4±5.3) and (18.4±9.1), respectively (P=0.008); the proportion (%) of blue-stained area under Masson's trichrome at d42 was (21.5±2.8), (23.4±2.5), (34.0±5.8) and (41.3±2.9) (P<0.05); the HYP contents (mg/L) at d42 of each group was (0.77±0.01), (1.26±0.01), (2.02±0.01) and (2.39±0.01) (P<0.01); the BALF levels of MDA (μmol/L) at d42 were (0.51±0.09), (0.87±0.12), (1.40±0.31) and (1.71±0.12) (P<0.001), and differences of these three indices at d42 reached statistical significance when comparing the Ctrl or GER group with the BLM or BLM+GER group (all P<0.05). The levels of pepsin, pH, interleukin (IL)-1β, transforming growth factor (TGF)-β1 and HYP at d28 and d42 were statistically different between the GER group and the Ctrl group (all P<0.05). As compared with the BLM group, the values of TGF-β1, HYP, p-Smad3, vimentin, p-ERK1/2 and cleaved caspase-3 at d28 and d42 were different in the BLM+GER group (all P<0.05). At both d28 and d42, the BALF levels of pepsin and pH were statistically different between the BLM and the Ctrl group, or between the BLM+GER group and the GER group (all P<0.05). Conclusions: Gastroesophageal reflux is induced through duodenal ligation, which activates proinflammatory and profibrotic signals in the lungs and significantly aggravates bleomycin-induced lung injury and fibrosis. In addition, pulmonary fibrosis may induce or worsen the extent of reflux.

Abstract
Objective:Imaging findings and treatment of sharp foreign bodies penetrating the esophagus to migrate in the neck were collected. Method:All of 9 cases were determined by CT imaging. The foreign bodies were removed in 8 cases through the lateral cervical approach. The last case was taken out by bronchoscope. Eight cases successfully removed the foreign bodies. No definite foreign body was found in 1 case. Result:There were no postoperative complications in 8 patients that successful removed of foreign bodies. All patients begin to eat normally after operation and were discharged from hospital in 7 days. Tracheoesophageal fistula occurred that happened to the patient that no foreign body was found in operation. So gastric tube was retained for 7 days. Conclusion:CT imaging should be performed to determine whether there is the possibility of foreign body penetrating out of the esophagus, for the patients who had explicit history but the foreignbodies could not be found by barium meal examination. If necessary, three-dimensional CT reconstruction of the neck should be performed to locate the foreign body. Surgical exploration should be done as soon as possible to avoid aimless migration of foreign bodies, and it is difficult to find it during operation.

Abstract
Objective: To study the relationship between human cytomegalovirus (HCMV) envelope glycoprotein gene H and clinical features of children with congenital cytomegalovirus infection. Methods: A cohort study was conducted. Newborns diagnosed with congenital cytomegalovirus infection, hospitalized in the Department of Neonatology and Neonatal Intensive Care Unit (NICU) of the Children's Hospital, Zhejiang University School of Medicine, were included from July 2013 to December 2015.HCMV-DNA gH typing in urine, sputum or blood was conducted. Patients then were divided into gH1 group and gH2 group according to gH genotypes. Patients' data during hospitalization in newborn and 3-5 years of follow-up were collected.The relationships between gH genotype and clinical manifestations, laboratory examinations, hearing loss and neurological prognosis were analyzed by chi-square test, t test and non-parametric test. Results: A total of 21 cases were enrolled as congenital HCMV infection and followed-up for 3-5 years. Among them, 14 (67%) were gH1 type and 7 (33%) were gH2 type. No mixed infection was found. In the two groups, there were no significant differences in the ratio of males (9/14 vs. 3/7,P=0.397), or birth weight ((2 609±686) vs. (3 021±451) g, t=-1.436, P=0.167). Gestational age of gH1 group was younger than that of gH2 group (38 (29-40) vs. 39(38-40) weeks, Z=-2.18, P=0.029). Moderate to severe hearing loss detected by neonatal auditory brainstem response were found in 40 ears (20 cases). It was higher in gH1 group than that in gH2 group (4/22 vs.0/18, χ(2)=5.145, P=0.023). In the imaging examination of the nervous system, the Alarcon score of gH1 group was lower than that of gH2 group (0.4±0.3 vs. 1.3±1.1, t=-2.459,P=0.024).No significant statistical difference was found in the probability of motor or language development lag in gH2 group and gH1 group (4/7 vs.4/14, P=0.346). Conclusions: Compared with gH2 infection, gH1 infection in children has a younger gestational age. The major type of hearing loss in neonatal period is gH1 infection. Children with gH2 congenital infections are more likely to suffer from nervous systems damage.

Abstract
Objective:To study the risk factors for the lateral neck lymph node metastasis(LNM) in patients with papillary thyroid carcinoma(PTC).Method:Total 145 cases of papillary thyroid carcinoma patients were reviewed. These patients were divided into the following 2 groups: a lateral LNM-positive group and a lateral LNM-negative group.Clinical factors and tumor ultrasound characteristics were recorded, and the final pathology results were recorded as well. Result: Univariate and multivariate analyses indicated that primary tumor size(pathological diameter) >1.0 cm, upper portion location and lymph node metastasis in central neck were the three risk factors for lateral LNM of PTC(OR=6.250,4.881,5.222,P<0.05). The lymph node metastasis in the lateral neck was not correlated obviously with gender, age, capsuleinvasion, multifocality and tumor ultrasonic characteristics(including illdefined and irregular in shape, calcification, hypervascularized). The probability of lateral LNM was then calculated according to the number of risk factors present in each of the 145 patients, using the three factors. When two or more factors were present, the probability increased up to 38.1 %(95%CI23-53).Conclusion: The present study provides that lateral LNM occurs mainly in patients, with a tumor size(pathological diameter) diameter>1.0 cm, with the primary tumor located in the upper part of the lobe and positive central compartment lymph node metastasis. The risk increased up when at least two of the three factors were present. So it needs to pay attention to the high risk factors seriously which effect lateral neck lymph node metastasis in patients with PTC, combined with ultrasonic characteristics of lateral cervical lymph node or more meticulous evaluations, to establish the lymph node dissection individually.

Thyroid hormone-induced expression of inflammatory cytokines interfere with resveratrol-induced anti-proliferation of oral cancer cells. Food Chem Toxicol 2019; 132:110693. [PMID: 31336132 DOI: 10.1016/j.fct.2019.110693] [Citation(s) in RCA: 27] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2019] [Revised: 06/26/2019] [Accepted: 07/19/2019] [Indexed: 12/15/2022]
Abstract
Thyroid hormone, L-thyroxine (T4), induces inflammatory genes expressions and promotes cancer growth. It also induces expression of the checkpoint programmed death-ligand 1 (PD-L1), which plays a vital role in cancer progression. On the other hand, resveratrol inhibits inflammatory genes expressions. Moreover, resveratrol increases nuclear inducible cyclooxygenase (COX)-2 accumulation, complexes with p53, and induces p53-dependent anti-proliferation. In this study, we investigated the effect of T4 on resveratrol-induced anti-proliferation in oral cancer. T4 increased the expression and cytoplasmic accumulation of PD-L1. Increased expressions of pro-inflammatory genes, interleukin (IL)-1β and transforming growth factor (TGF)-β1, were shown to stimulate PD-L1 expression. T4 stimulated pro-inflammatory and proliferative genes expressions, and oral cancer cells proliferation. In contrast, resveratrol inhibited those genes and activated anti-proliferative genes. T4 retained resveratrol-induced COX-2 in cytoplasm and prevented COX-2 nuclear accumulation when resveratrol treated cancer cells. A specific signal transducer and activator of transcription 3 (STAT3) inhibitor, S31-201, blocked T4-induced inhibition and restored resveratrol-induced nuclear COX-2 accumulation. By inhibiting the T4-activated STAT3 signal transduction axis with S31-201, resveratrol was able to sequentially reestablish COX-2/p53-dependent gene expressions and anti-proliferation. These findings provide a novel understanding of the inhibitory effects of T4 on resveratrol-induced anticancer properties via the sequential expression of PD-L1 and inflammatory genes.

Abstract
Objective: To explore the clinical characteristics and treatment methods of esophageal foreign body. Method: The clinical data of 234 patients with esophageal foreign bodies admitted to our department from January 2015 to August 2018 were retrospectively analyzed, including course time, foreign body types, surgical methods, imaging manifestations and treatment related complications. Result: The diagnosis of esophageal foreign bodies was confirmed by esophageal CT or esophageal barium meal X-ray examination before operation in 234 patients. Course time varied from 3 hours to 7 days, and the jujube nucleus was the most common food-borne foreign body.223 patients underwent esophagoscopic exploration and foreign body removal under general intravenous anesthesia, 11 of them had no definite esophageal foreign body, 22 had esophageal perforation and periesophagitis. After removal of foreign body, the nasogastric feeding tube was inserted. About 10 days later, the nasogastric feeding tube was removed when they got healthy. Nine cases underwent cervical abscess incision and drainage under general anesthesia. The average postoperative hospital day was 11 days. Conclusion: The rigid esophagoscopy is a safe and effective method for the esophageal foreign bodies. And neck abscess incision must be necessary,when they suffered from esophageal perforation with neck abscess and other serious complications.

Abstract
Objective:The aim of this study is to discuss the clinical presentation, imaging examination and treatment of neck abscess and mediastinal abscess following esophageal perforation induced by esophageal foreign body. Method:Six patients all underwent lateral neck incision and drainage of neck abscess. Simultaneously, mediastinal abscess drainage was performed in 3 cases with mediastinal abscess. Result:All 6 patients were cured. The median time of extraction of gastric tube was 11 days (7-30 days). All patients were not treated with tracheotomy. Conclusion:Neck and chest CT should be done as soon as possible for suspected patients to definite the location of foreign body and the relationship between foreign body and surrounding structures. Patient who were suspected with neck abscess and mediastinal abscess should undergo surgery to remove foreign body and drain the infectious deep neck and mediastinal spaces as early as possible.

Abstract
Nasal glioma is a rare congenital malformation in maxillofacial region. It is sluggish, benign, non-tumorous and with low recurrence rate. It is important to evaluate whether there is any intracranial connection before the operation through CT or MRI to avoid the serious intracranial complications. We reported a case of a adult with a nasal glioma in sphenoid sinus, and discuss clinical characteristics, diagnosis, and pathology.

Abstract
Traditional herb medicine, golden thread (Anoectochilus formosanus Hayata) has been used to treat various diseases. Hyperglycemia induces generation of reactive oxygen species (ROS) and enhancement of oxidative stress which are risk factors for cancer progression and metastasis. In this study, we evaluated hypoglycemic effect of A. formosanus extracts (AFEs) in an inducible hyperglycemia animal model and its capacity of free-radical scavenging to establish hyperglycemia-related carcinogenesis. AFE reduced blood glucose in hyperglycemic mice while there was no change in control group. The incremental area under blood glucose response curve was decreased significantly in hyperglycemic mice treated with AFE in a dose-dependent manner. AFE and metformin at the same administrated dose of 50 mg/kg showed similar effect on intraperitoneal glucose tolerance test in hyperglycemic mice. Free-radical scavenger capacity of AFE was concentration dependent and 200 μg/ml of AFE was able to reduce more than 41% of the free radical. Treatment of cancer cells with AFE inhibited constitutive PD-L1 expression and its protein accumulation. It also induced expression of pro-apoptotic genes but inhibited proliferative and metastatic genes. In addition, it induced anti-proliferation in cancer cells. The results suggested that AFE not only reduced blood glucose concentration as metformin but also showed its potential use in cancer immune chemoprevention/therapy via hypoglycemic effect, ROS scavenging and PD-L1 suppression.

Abstract
Cancer resistance to chemotherapeutic agents is a major issue in the management of cancer patients. Overexpression of the ribonucleotide reductase regulatory subunit M2 (RRM2) has been associated with aggressive cancer behavior and chemoresistance. Nano-diamino-tetrac (NDAT) is a nanoparticulate derivative of tetraiodothyroacetic acid (tetrac), which exerts anticancer properties via several mechanisms and downregulates RRM2 gene expression in cancer cells. Resveratrol is a stilbenoid phytoalexin which binds to a specific site on the cell surface integrin αvβ3 to trigger cancer cell death via nuclear translocation of COX-2. Here we report that resveratrol paradoxically activates RRM2 gene expression and protein translation in colon cancer cells. This unanticipated effect inhibits resveratrol-induced COX-2 nuclear accumulation. RRM2 downregulation, whether achieved by RNA interference or treatment with NDAT, enhanced resveratrol-induced COX-2 gene expression and nuclear uptake which is essential to integrin αvβ3-mediated-resveratrol-induced antiproliferation in cancer cells. Elsewhere, NDAT downregulated resveratrol-induced RRM2 expression in vivo but potentiated the anticancer effect of the stilbene. These findings suggest that RRM2 appears as a cancer cell defense mechanism which can hinder the anticancer effect of the stilbene via the integrin αvβ3 axis. Furthermore, the antagonistic effect of RRM2 against resveratrol is counteracted by the administration of NDAT.

Abstract
Objective: To compare the difference of measuring the length of styloid process between spiral CT with high resolution and cone-beam CT(CBCT). Methods: Five specimens (including 5 pairs of styloid processes) were selected randomly from the Anatomy Laboratory of Otolaryngology Department, all the specimens underwent spiral CT with high resolution and cone-beam CT retrospectively.With the original DICOM data, the styloid processes were shown in one plate by multiple plate reconstruction technique, and later the length of styloid processes of each specimen were measured separately by software NNT Viewer (to CBCT) or Osrix (to spiral CT with high resolution). Results: The length of styloid processes measured by CBCT and spiral CT was (26.8±5.5) mm and (27.1±5.4) mm respectively, and there was no statistical difference between the two groups. Conclusion: In respect of measuring the length of styloid process, the CBCT has the same value in clinical practice comparing to spiral CT with high resolution.

Abstract
Ovarian cancer is the leading cause of death in gynecological diseases. Thyroid hormone promotes proliferation of ovarian cancer cells via cell surface receptor integrin αvβ3 that activates extracellular regulated kinase (ERK1/2). However, the mechanisms are still not fully understood. Thyroxine (T4) at a physiologic total hormone concentration (10−7 M) significantly increased proliferating cell nuclear antigen (PCNA) abundance in these cell lines, as did 3, 5, 3′-triiodo-L-thyronine (T3) at a supraphysiologic concentration. Thyroid hormone (T4 and T3) treatment of human ovarian cancer cells resulted in enhanced activation of the Ras/MAPK(ERK1/2) signal transduction pathway. An MEK inhibitor (PD98059) blocked hormone-induced cell proliferation but not ER phosphorylation. Knock-down of either integrin αv or β3 by RNAi blocked thyroid hormone-induced phosphorylation of ERK1/2. We also found that thyroid hormone causes elevated phosphorylation and nuclear enrichment of estrogen receptor α (ERα). Confocal microscopy indicated that both T4 and estradiol (E2) caused nuclear translocation of integrin αv and phosphorylation of ERα. The specific ERα antagonist (ICI 182,780; fulvestrant) blocked T4-induced ERK1/2 activation, ERα phosphorylation, PCNA expression and proliferation. The nuclear co-localization of integrin αv and phosphorylated ERα was inhibited by ICI. ICI time-course studies indicated that mechanisms involved in T4- and E2-induced nuclear co-localization of phosphorylated ERα and integrin αv are dissimilar. Chromatin immunoprecipitation results showed that T4-induced binding of integrin αv monomer to ERα promoter and this was reduced by ICI. In summary, thyroid hormone stimulates proliferation of ovarian cancer cells via crosstalk between integrin αv and ERα, mimicking functions of E2.

Abstract
The molecular pathogenesis of colorectal cancer encompasses the activation of several oncogenic signaling pathways that include the Wnt/β-catenin pathway and the overexpression of high mobility group protein A2 (HMGA2). Resveratrol - the polyphenolic phytoalexin - binds to integrin αvβ3 to induce apoptosis in cancer cells via cyclooxygenase 2 (COX-2) nuclear accumulation and p53-dependent apoptosis. Tetraiodothyroacetic acid (tetrac) is a de-aminated derivative of l-thyroxine (T4), which - in contrast to the parental hormone - impairs cancer cell proliferation. In the current study, we found that tetrac promoted resveratrol-induced anti-proliferation in colon cancer cell lines, in primary cultures of colon cancer cells, and in vivo The mechanisms implicated in this action involved the downregulation of nuclear β-catenin and HMGA2, which are capable of compromising resveratrol-induced COX-2 nuclear translocation. Silencing of either β-catenin or HMGA2 promoted resveratrol-induced anti-proliferation and COX-2 nuclear accumulation which is essential for integrin αvβ3-mediated-resveratrol-induced apoptosis in cancer cells. Concurrently, tetrac enhanced nuclear abundance of chibby family member 1, the nuclear β-catenin antagonist, which may further compromise the nuclear β-catenin-dependent gene expression and proliferation. Taken together, these results suggest that tetrac targets β-catenin and HMGA2 to promote resveratrol-induced-anti-proliferation in colon cancers, highlighting its potential in anti-cancer combination therapy.

Abstract
OBJECTIVE Retro-laparoscopic partial nephrectomy is a challenge for ventro-renal tumors, especially hilar tumors. The tumors are partial or entirely out of operative field and there is blind space for operation. To solve this problem, a set of techniques including renal pedicle rotation is developed. METHODS A set of techniques including renal pedicle rotation, double-layer suture, early artery unclamping for retro-laparoscopic nephrectomy for ventro-renal tumors, especially hilar tumors were developed. Hilar tumors were located anteriorly to the angle of the renal and renal arteries and in contact with the anterior surface of the renal artery. The evaluation of the outcomes included the operation time, warm ischemia time, estimated haemorrhage, surgical margin, renal function after operation, and complications. This study reviewed the data of 28 patients with ventro-renal tumor, including 15 patients with complex hilar tumors. RESULTS The average tumor size was (3.8±0.5) cm. The average R.E.N.A.L score was 8 (ranging from 7 to 9). The average warm ischemia time was (23.8±4.7) min, and suture time was (26.2±6.5) min, and operation time was (124.1±12.1) min. The median hospital stay was 4 days and the average estimated haemorrhage was (139.1±54.0) mL. All the surgeries were operated under laparoscope and no surgery switched to open surgery. Seven patients developed Clavien Dindo I-II complications after operation. Three patients (10.7%) developed collective system damage and received repair of collective system in time and three patients (10.7%) developed slightly gross hematuria (Clavien-Dindo I). Two patients developed wound infection (Clavien-Dind II). Three patients (10.7%) got renal vein clamped because of capillary hemorrhage from basilar part of tumors. There were 14 patients received early unclamping of renal artery, and no obvious renal vessel damage was found. There were statistically significant differences between the serum creatinine levels (P<0.05) and the estimated glomerular filtration rates (P=0.02) before and after surgery. All the patients' serum creatinine levels were in normal range and no patient needed regular dialysis. There was no positive surgical margin and the median follow-up was 7 months without local recurrence or distant metastasis. CONCLUSION It is safe and effective to apply renal pedicle rotation technique in retro-laparoscopic partial nephrectomy for ventro-renal tumors. The short-term follow-up results are optimistic, but long follow-up is required.

Abstract
Patient presented as a 74-year-old male complaining of hoarseness. Electronic laryngoscope showed a neoplasm whose size was about 1.0 cm×0.5 cm×0.5 cm at anterior commissure. A surgery was conducted to excise the neoplasm en bloc. The histopathological and immunohistochemistry examination suggested inflammatory myofibroblastic tumor. A month later, the patient presented with dyspnea and blood-stained sputum. CT scan of neck showed an occupation lesions under glottis. A tracheotomy and a CO₂ laser surgery was conducted due to patient's will. The histopathological and immunohistochemistry examination suggested undifferentiated sarcoma. We advised him keeping a tracheal cannula to receive further treatment such as radiotherapy or chemotherapy in oncology department, but the patient was not compliant with care instructions for personal reason. He was readmitted 2 months later for dyspnea after plugging the tube. Electronic laryngoscope showed a large neoplasm occupied the laryngeal vestibule, covering the glottis. CT and MRI scan showed the lesion involved spaces of supraglottic, glottic, subglottic and soft tissue around larynx. Hence, a total laryngotomy and bilateral functional neck dissection was conducted. The histopathological examination agreed with the former one. Three weeks later, the skin around his tracheal cannula swelled,ulcerated and pyorrheal. After 10 days of dressing change, patient died of uncontrolled infection.

Abstract
Objective:To investigate the risk factors of central neck lymph node metastasis (CNLNM) in cN0 papillary thyroid carcinoma. Method:Retrospective analysis of 114 patients with papillary thyroid carcinoma in stage of cN0 who underwent primary treatment. Collected the clinical and pathological data, used the univariate and multivariate analysis to investigate the risk factors of central neck lymph node metastasis and high volume central neck lymph node metastasis.Result:In the univariate analysis, age (48.2% in<45 years vs 27.6% in≥45 years), multifocal (51% with vs 27.7% without), nodular goiter (58.8% with vs 28.7% without), showed significant difference in prevalence of CNLNM. Age (14.3% in<45 years vs 1.7% in≥45 years), tumor size (19.2% >1 cm vs 4.5%≤1 cm) showed significant difference in prevalence of high volume CNLNM. Inmultivariate analysis, age (RR= 0.304), multifocal (RR= 3.637) and nodular goiter (RR= 4.132) showed the independent risk factor of CNLNM.Conclusion:For cN0 patients with thyroid papillary carcinoma, if the age is younger than 45 years old, the tumor is multifocal, or associatedwith nodular goiter, the surgery should be more aggressive in the prophylactic central neck dissection.
