Abstract
Objective: To study the clinicopathological features of Sjogren's syndrome (SS) with liver injury and to improve the understanding of this disease. Methods: Forty-nine patients with SS complicated with liver injury were collected from Beijing Ditan Hospital, Capital Medical University from October 2008 to January 2022. All patients underwent ultrasound-guided liver biopsy, and all specimens were stained with HE. The histopathologic characteristics were observed and the pathologic indexes were graded. Immunohistochemical stains for CK7, CK19, CD38, MUM1 and CD10 were performed by EnVision method; and special histochemical stains for reticulin, Masson's trichrome, Rhodanine, Prussian blue, periodic acid Schiff (PAS) and D-PAS stains were conducted. Results: The age of patients ranged from 31 to 66 years, including 3 males and 46 females. SS combined with drug-induced liver injury was the most common (22 cases, 44.9%), followed by autoimmune liver disease (13 cases, 26.5%, including primary biliary cholangitis in eight cases, autoimmune hepatitis in 3 cases, and PBC-AIH overlap syndrome in 2 cases), non-alcoholic fatty liver disease (NAFLD, 9 cases, 18.4%) and other lesions (5 cases, 10.2%; including 3 cases of nonspecific liver inflammation, 1 case of liver amyloidosis, and 1 case of porto-sinusoidal vascular disease). Among them, 28 cases (57.1%) were associated with obvious interlobular bile duct injury, mainly in SS combined with PBC group and drug-induced liver injury group. Twenty-three cases (46.9%) were associated with hepatocyte steatosis of varying degrees. In SS with autoimmune liver disease group, ISHAK score, degree of fibrosis bile duct injury, bile duct remodeling, lymphocyte infiltration of portal area, and plasma cell infiltration, MUM1 and CD38 expression; serum ALP and GGT, IgM; elevated globulin; positive AMA, proportion of AMA-M2 positive and IgM positive were all significantly higher than those in other groups(all P<0.05). Serum ALT, direct bilirubin and SSA positive ratio in SS combined with drug liver group were significantly higher than those in other groups(all P<0.05). The serum total cholesterol level in SS combined with PBC group (P=0.006) and NALFD group (P=0.011) were significantly higher than those in other groups (P<0.05). Conclusions: The pathologic manifestations of SS patients with liver injury are varied. The inflammatory lesions of SS patients with autoimmune liver disease are the most serious, and the inflammatory lesions of SS patients with non-alcoholic fatty liver disease and non-specific inflammation are mild. Comprehensive analysis of liver histopathologic changes and laboratory findings is helpful for the diagnosis of SS complicated with different types of liver injury.

Abstract
Objective: To analyze the diagnosis and surgical treatment of high-risk anomalous aortic origin of coronary artery (AAOCA). Methods: This is a retrospective case series study. From January 2016 to July 2023, 24 cases of high-risk AAOCA underwent surgical treatment in Department of Cardiac Surgery, Guangdong Provincial People's Hospital. There were 18 males and 6 females, operatively aged (M (IQR)) 13 (26) years (range: 0.3 to 57.0 years). They were confirmed by cardiac ultrasound and cardiac CT, all of which had anomalous coronary running between the aorta and the pulmonary artery. There were 15 cases of the right coronary artery from the left aortic sinus of Valsalva, 6 cases of left coronary artery from the right aortic sinus of Valsalva, 3 cases of the sigle coronary artery. Only 3 patients had no obvious related symptoms (2 cases were complicated with a positive exercise stress test and 1 case with other intracardiac malformations), 21 cases had a history of chest tightness, chest pain, or syncope after exercise. Three patients suffered syncope after exercise and underwent cardiopulmonary resuscitation (2 cases were treated with an extracorporeal membrane oxygenerator (ECMO)). The gap from the first symptom to the diagnosis was 4.0 (11.5) months (range: 0.2 to 84.0 months). The detection rate of coronary artery abnormalities suggested by the first cardiac ultrasound was only 37.5% (9/24). Seven patients were complicated with other cardiac diseases (4 cases with congenital heart defects, 2 cases with coronary atherosclerotic heart disease, 1 case with mitral valve disease). Results: All 24 patients underwent surgical treatment (23 cases underwent abnormal coronary artery unroofing, 1 case underwent coronary artery bypass grafting), and 5 patients underwent other intracardiac malformation correction at the same time. There were no death or surgery related complications in the hospital for 30 days after the operation. A patient with preoperative extracorporeal cardiopulmonary resuscitation was continuously assisted by ECMO after emergency AAOCA correction and had complications such as limb ischemia necrosis and renal dysfunction after the operation. During the follow-up of 2.2 (3.3) years (range: 1 month to 7.2 years), one patient who previously underwent percutaneous transluminal coronary angioplasty with a stent implant experienced significant postoperative symptomatic relief, and the other discharged patients had no related symptoms. Conclusions: The accurate rate of initial diagnosis for high-risk AAOCA is still low, but the risk of cardiovascular accidents is high. For sports-related chest pain and other symptoms, more attention should be paid to the detection of AAOCA, especially for adolescents. Exercise stress testing can be helpful in evaluating the cardiovascular risk of asymptomatic AAOCA. Instant surgical treatment can achieve satisfactory curative effects.

Abstract
Objective: To investigate the safety and efficacy of the TRIANGLE operation after neoadjuvant chemotherapy in locally advanced pancreatic cancer(LAPC). Methods: This study is a retrospective case series analysis. Between January 2020 and December 2022, a total of 103 patients were diagnosed as LAPC who underwent neoadjuvant chemotherapy at the Pancreas Center, the First Affiliated Hospital of Nanjing Medical University. Among them, 26 patients (25.2%) underwent the TRIANGLE operation. There were 15 males and 11 females,with a age of (59±7) years (range: 49 to 74 years). The pre-treatment serum CA19-9(M(IQR)) was 248.8(391.6)U/ml (range: 0 to 1 428 U/ml),and the serum carcinoembryonic antigen was 4.1(3.8)μg/L(range: 1.4 to 13.4 μg/L). The neoadjuvant chemotherapy regimens included: mFOLFIRINOX regimen in 6 cases(23.1%), GnP regimen in 14 cases(53.8%), and mFOLFIRINOX+GnP regimen in 6 cases(23.1%). The follow-up duration extended until June 2023 or until the occurrence of the patient's death or loss to follow-up. The Kaplan-Meier method was employed to estimate the 1-year and 3-year overall survival rates. Results: After neoadjuvant chemotherapy,CA19-9 levels decreased by 92.3(40.1)%(range:2.1% to 97.7%). Evaluation of the response to treatment revealed 13 cases(50.0%) of stable disease,11 cases(42.3%) of partial response,and 2 cases(7.7%) of complete response. The surgical operation consisted of 12 cases(46.2%) of pancreaticoduodenectomy,12 cases(46.2%) of distal pancreatectomy,and 2 cases(7.7%) of total pancreatectomy. Margin determination was based on the "standardised pathology protocol" and the "1 mm" principle. No R2 and R1(direct) resections were observed,while the R0 resection rate was 61.5%(16/26), and the R1(1 mm) resection rate was 38.5%(10/26).The R1(1 mm) resection rates for the anterior margin,posterior margin,transected margin,portal vein groove margin,and uncinate margin were 23.1%(6/26),19.2%(5/26),12.5%(3/24),2/14, and 1/12, respectively. The overall postoperative complication rate was 57.8%(15/26),with major complications including grade B/C pancreatic fistula 25.0%(6/24,excluding 2 cases of total pancreatectomy),delayed gastric emptying in 23.1%(6/26),wound complications 11.5%(3/26),postoperative hemorrhage 7.7%(2/26), chylous fistula 7.7%(2/26) and bile fistula 3.8%(1/26). No reoperation was performed during the perioperative period(<90 days). One patient died on the 32nd day postoperatively due to a ruptured pseudoaneurysm. A total of 25 patients were followed up,with a follow-up time of 21(24)months(range: 8 to 42 months). During the follow-up period,8 cases(32.0%) died due to tumor recurrence and metastasis,while 17 patients(68.0%) remained alive,including 11 cases of disease-free survival,5 cases of distant metastasis,and 1 case of local recurrence. The overall survival rates at 1- and 3-year after the initiation of neoadjuvant chemotherapy were 95.8% and 58.9%, respectively. The overall survival rates at 1- and 3-year after surgery were 77.7% and 57.8%, respectively. Conclusion: Performing pancreatoduodenectomy according to the Heidelberg triangle protocol in LAPC patients after neoadjuvant chemotherapy might increase the R0 resection rate without increasing perioperative mortality or the incidence of major postoperative complications.

Abstract
Objective: To investigate the application and effect of capillary fascia preservation between the recurrent laryngeal nerve (RLN) and common carotid artery (fascia preservation method) in nerve protection when dissecting right level Ⅵ lymph nodes for patients with papillary thyroid carcinoma. Methods: A retrospective cohort study enrolling 195 patients with papillary thyroid carcinoma undergoing right level Ⅵ lymph node dissection in Beijing Tongren Hospital from March 2021 to August 2022 was carried out. The RLN was dissected by fascia preservation method in study group and by routine method in control group. The intraoperative electrical signal amplitude of the RLN, the number of dissected lymph nodes, and the postoperative complications were recorded and analyzed. Results: A total of 195 patients (study group: 94 cases, control group: 101 cases) were collected. There were 71 males and 124 females, with the median age of 32 (39, 51) years. In the study group, the total number of right level Ⅵ lymph nodes was significantly larger than the number of right Ⅵa level lymph nodes [8 (6, 11) vs 6 (4, 8), P<0.001]. There were no significant differences between the two groups in the number of level Ⅵa or level Ⅵb lymph nodes [Ⅵa: 6 (4, 8) vs 5 (3, 7), P=0.373; Ⅵb: 3 (1, 4) vs 2 (1, 4), P=0.337] and metastasis rate [Ⅵa: 51.1% (48/94) vs 52.5% (53/101), P=0.844; Ⅵb: 12.8% (12/94) vs 15.8% (16/101), P=0.541]. The ratio of electromyography (EMG) amplitude R2 in lower level Ⅵ and entry into larynx (grouped as>90%, 50%~90%,<50%) in the study group was significantly higher than that in the control group (P<0.001). No significant differences were detected between the two groups in temporary RLN paralysis [1.1% (1/94) vs 2.0% (2/101), P=1.000]. Conclusions: Fascia preservation method can decrease the stimulus and traction to RLN and preserve the capillary network serving RLN. It can thoroughly dissect lymph nodes and decrease the injury of RLN.

Abstract
Objective: To investigate the clinical efficacy of distal pancreatectomy with celiac axis resection(DP-CAR). Methods: A total of 89 consecutive patients (50 males and 39 females) who were diagnosed with pancreatic body cancer and underwent DP-CAR in Pancreas Center,First Affiliated Hospital of Nanjing Medical University between September 2013 and June 2022 were retrospectively reviewed. There were 50 males and 39 females,with age(M(IQR)) of 63(12) years(range:43 to 81 years). Perioperative parameters,pathology results and follow-up data of these patients were analyzed,χ2 or Fisher's test for categorical data while the Wilcoxon test for quantitative data. Survival results were estimated by the Kaplan-Meier survival method. Results: Among 89 cases,cases combined with portal vein-superior mesenteric vein or organ resection accounted for 22.5% (20/89) and 42.7% (38/89),respectively. The operative time,blood loss and postoperative hospital stay were 270 (110) minutes,300 (300) ml and 13 (10) days,respectively. The overall morbidity rate was 67.4% (60/89) while the major morbidity was 11.2% (10/89). The increase rate in transient liver enzymes was 42.7% (38/89),3.4% (3/89) for liver failure,53.9% (48/89) for clinically relevant postoperative pancreatic fistula,1.1% (1/89) for bile leak,3.4% (3/89) for chylous leak of grade B and C,11.2% (10/89) for abdominal infection,9.0% (8/89) for postoperative hemorrhage of grade B and C,4.5% (4/89) for delayed gastric emptying,6.7% (6/89) for deep vein thrombosis,3.4% (3/89) for reoperation,4.5% (4/89)for hospital mortality,7.9% (7/89) for 90-day mortality. The pathological type was pancreatic cancer for all 89 cases and pancreatic ductal adenocarcinoma made up 92.1% (82/89). The tumor size was 4.8(2.0) cm, ranging from 1.5 to 12.0 cm. The number of lymph nodes harvested was 14 (13)(range:2 to 33),with a positive lymph node rate of 13.0% (24.0%). The resection R0 rate was 30.0% (24/80) and the R1 (<1 mm) rate was 58.8% (47/80). The median overall survival time was 21.3 months (95%CI: 15.6 to 24.3) and the median disease-free survival time was 19.1 months (95%CI: 11.7 to 25.1). The overall survival at 1-year and 2-year were 69.60% and 39.52%. The median survival time of 58 patients with adjuvant chemotherapy was 24.3 months (95%CI: 17.8 to 32.3) while that of 13 patients without any kind of adjuvant therapy was 8.4 months (95%CI: 7.3 to 22.3). Seven patients accepted neoadjuvant chemotherapy and there was no significant morbidity among them,with a resection rate of R0 of 5/7. Conclusion: DP-CAR is safe and feasible for selective cases,which could be more valuable in improving long-term survival when combined with (neo) adjuvant therapy.

Abstract
Objective: To investigate the morphology and immunohistochemical (IHC) expression of pseudostratified ependymal tubules in ovarian mature teratoma (MT). Methods: Five cases of ovarian MT with pseudostratified ependymal tubules were collected from Shenzhen Hospital(Futian) of Guangzhou University of Chinese Medicine and the Eighth Affiliated Hospital of Sun Yat-sen University from March 2019 to March 2022. In addition, 15 cases of ovarian MT with monolayer ependymal epithelium from Shenzhen Hospital (Futian) of Guangzhou University of Chinese medicine and seven cases of immature teratoma (IMT) from Hainan Provincial People's Hospital from March 2019 to March 2022 were collected as control. The morphologic characteristics and immunophenotypes of pseudostratified ependymal tubules, monolayer ependymal epithelium, and primitive neural epithelial tubules were observed and compared by H&E stain and IHC expression pattern of genes related to the differentiation status of neuroepithelium, namely SALL4, Glypican3, nestin, SOX2, Foxj1, and Ki-67. Results: Mean age of the five patients of ovarian MT with pseudostratified ependymal tubules was 26 years (range from 19 to 31 years). Two tumors were located in the left ovary and three in the right. All five cases were excised, and clinical follow-up was available (mean follow-up 1.5 years; range 0.5 to 3 years). No recurrence was noted in any cases. The pseudostratified ependymal tubules of ovarian MT, which were lined with columnar or oval epithelia up to 4-6 layers, were morphologically similar to the primitive neuroepithelial tubules of IMT and different from monolayer ependymal epithelium of ovarian MT. By immunohistochemistry, SALL4 and Glypican3 were negative, Foxj1 was positive and Ki-67 index was lower in the pseudostratified ependymal tubules and the monolayer ependymal epithelium of ovarian MT. However, the primitive neuroepithelial tubules of IMT showed variably expression of SALL4 and Glypican3, were negative for Foxj1 and high Ki-67 index. All the above three groups expressed nestin and SOX2. Conclusions: The pseudostratified ependymal tubules of ovarian MT, which have morphological similarities to the primitive neuroepithelial tubules of IMT, are similar to the monolayer ependymal epithelia of the MT in immunophenotype. IHC assessment of Foxj1 and Ki-67 is helpful to differentiate the pseudostratified ependymal tubules of ovarian MT from the primitive neuroepithelial tubules of IMT.

Abstract
Objectives: To evaluate the positive rate of left posterior lymph nodes of the superior mesenteric artery (14cd-LN) in patients undergoing pancreaticoduodenectomy for pancreatic head carcinoma,to analyze the impact of 14cd-LN dissection on lymph node staging and tumor TNM staging. Methods: The clinical and pathological data of 103 consecutive patients with pancreatic cancer who underwent pancreaticoduodenectomy at Pancreatic Center,the First Affiliated Hospital of Nanjing Medical University from January to December 2022 were analyzed,retrospectively. There were 69 males and 34 females,with an age(M (IQR))of 63.0 (14.0) years (range:48.0 to 86.0 years). The χ2 test and Fisher's exact probability method was used for comparison of the count data between the groups,respectively. The rank sum test was used for comparison of the measurement data between groups. Univariate and multivariate Logistic regression analyzes were used for the analysis of risk factors. Results: All 103 patients underwent pancreaticoduodenectomy successfully using the left-sided uncinate process and the artery first approach. Pathological examination showed pancreatic ductal adenocarcinoma in all cases. The location of the tumors was the pancreatic head in 40 cases,pancreatic head-uncinate in 45 cases,and pancreatic head-neck in 18 cases. Of the 103 patients,38 cases had moderately differentiated tumor and 65 cases had poorly differentiated tumor. The diameter of the lesions was 3.2 (0.8) cm (range:1.7 to 6.5 cm),the number of lymph nodes harvested was 25 (10) (range:11 to 53),and the number of positive lymph nodes was 1 (3) (range:0 to 40). The lymph node stage was stage N0 in 35 cases (34.0%),stage N1 in 43 cases (41.7%),and stage N2 in 25 cases (24.3%). TNM staging was stage ⅠA in 5 cases (4.9%),stage ⅠB in 19 cases (18.4%),stage ⅡA in 2 cases (1.9%),stage ⅡB in 38 cases (36.9%),stage Ⅲ in 38 cases (36.9%),and stage Ⅳ in 1 case (1.0%). In 103 patients with pancreatic head cancer,the overall positivity rate for 14cd-LN was 31.1% (32/103),and the positive rates for 14c-LN and 14d-LN were 21.4% (22/103) and 18.4% (19/103),respectively. 14cd-LN dissection increased the number of lymph nodes (P<0.01) and positive lymph nodes (P<0.01). As a result of the 14cd-LN dissection,the lymph node stage was changed in 6 patients,including 5 patients changed from N0 to N1 and 1 patient changed from N1 to N2. Similarly,the TNM stage was changed in 5 patients,including 2 patients changed from stage ⅠB to ⅡB,2 patients changed from stage ⅡA to ⅡB,and 1 patient changed from stage ⅡB to Ⅲ. Tumors located in the pancreatic head-uncinate (OR=3.43,95%CI:1.08 to 10.93,P=0.037) and the positivity of 7,8,9,12 LN (OR=5.45,95%CI:1.45 to 20.44,P=0.012) were independent risk factors for 14c-LN metastasis; while tumors with diameter >3 cm (OR=3.93,95%CI:1.08 to 14.33,P=0.038) and the positivity of 7,8,9,12 LN (OR=11.09,95%CI:2.69 to 45.80,P=0.001) were independent risk factors for 14d-LN metastasis. Conclusion: Due to its high positive rate in pancreatic head cancer,dissection of 14cd-LN during pancreaticoduodenectomy should be recommended,which can increase the number of lymph nodes harvested,provide a more accurate lymph node staging and TNM staging.

Abstract
To develop the dressings that can both inhibit bacterial infection and actively promote healing is of great importance for wound repair and the development of medical technology. Electrical stimulation has multiple roles in wound healing, including hemostasis, antibacterial, anti-inflammatory, guidance of cell migration, promotion of re-epithelialization, and proliferation of cells. Metal micro-battery can provide a stable source of electrical stimulation energy without an external power source. Thus, the integration of metal micro-battery with medical dressings opens up new opportunities for the wireless application of electrical stimulation in wound repair. In this review, the mechanism of the effect of electrical stimulation on wound healing is systematically presented, then recent advances in metal micro-battery dressings, including preparation methods, antibacterial performance, and healing properties are mainly introduced, and the current challenges and prospects of metal micro-battery dressings are also provided.

Abstract
Objectives: To examine the short-term and mid-term effects of surgical treatment of obstructive hypertrophic cardiomyopathy (HCM) in one center. Methods: The perioperative data and short-term follow-up outcomes of 421 patients with obstructive HCM who received surgical treatment at Department of Cardiac Surgery, Zhongshan Hospital, Fudan University from January 2017 to December 2021 were analyzed retrospectively. There were 207 males and 214 females, aged (56.5±11.7) years (range: 19 to 78 years). Preoperative New York Heart Association (NYHA) classification included 45 cases of class Ⅱ, 328 cases in class Ⅲ, and 48 cases in class Ⅳ. Fifty-eight patients were diagnosed with latent obstructive HCM and 257 patients had moderate or more mitral regurgitation with 56 patients suffering from intrinsic mitral valve diseases. All procedures were completed by a multidisciplinary team, including professional echocardiologists involving in preoperative planning for proper mitral valve management strategies and intraoperative monitoring. A total of 338 patients underwent septal myectomy alone, and 59 patients underwent mitral valve surgery along with myectomy. A single transaortic approach was used in 355 patients, and a right atrial-atrial septal/atrial sulcus approach was used in 51 other patients. Long-handled minimally invasive surgical instruments were used for the procedures. Student t test, Wilcoxon rank sum test, χ2 test or Fisher exact test were used to compare the data before and after surgery. Results: The aortic cross-clamping time of septal myectomy alone was (34.3±8.5) minutes (range: 21 to 94 minutes). Eighteen patients had intraoperative adverse events and underwent immediate reoperation, including residual obstruction (10 patients), left ventricular free wall rupture (4 patients), ventricular septal perforation (3 patients), and aortic valve perforation (1 patient). Four patients died during hospitalization, and 11 patients developed complete atrioventricular block requiring permanent pacemaker implantation. After discharge, 384 (92.1%) patients received a follow-up visit with a median duration of 9 months. All follow-up patients survived with significantly improved NYHA classifications: 216 patients in class Ⅰ and 168 patients in class Ⅱ (χ2=662.73, P<0.01 as compared to baseline). At 6 months after surgery, follow-up echocardiography showed that the thickness of the ventricular septum ((13.6±2.5) mm vs. (18.2±3.0) mm, t=23.51, P<0.01) and the peak left ventricular outflow tract gradient ((12.0±6.3) mmHg vs. (93.4±19.8) mmHg, 1 mmHg=0.133 kPa, t=78.29, P<0.01) were both significantly lower than baseline values. Conclusion: The construction of the surgical team (including echocardiography experts), proper mitral valve management strategies, identification and management of sub-mitral-valve abnormalities, and application of long-handled minimally invasive surgical instruments are important for the successful implementation of septal myectomy with satisfactory short-and medium-term outcomes.

Abstract
Fontan-associated liver disease (FALD) is one of the main complications after the Fontan procedure, manifesting mostly as liver fibrosis and even cirrhosis, with a high incidence rate and a lack of typical clinical symptoms that seriously affect patient prognosis. The specific cause is unknown, although it is considered to be associated with long-term elevated central venous pressure, impaired hepatic artery blood flow, and other relevant factors. The absence of association between laboratory tests, imaging data, and the severity of liver fibrosis makes clinical diagnosis and monitoring difficult. A liver biopsy is the gold standard for diagnosing and staging liver fibrosis. The most important risk factor for FALD is time following the Fontan procedure; therefore, it is recommended to do a liver biopsy 10 years after the Fontan procedure and to be cautious for the presence of hepatocellular carcinoma. Combined heart-liver transplantation is a recommended choice with favorable outcomes for patients with Fontan circulatory failure and severe hepatic fibrosis.

Abstract
Objective: To investigate the clinical characteristics and risk factors of postoperative recurrence in papillary thyroid carcinoma (PTC) patients with recurrent laryngeal nerve (RLN) invasion. Methods: The data of PTC patients with recurrent laryngeal nerve invasion treated in Beijing Tongren Hospital, Capital Medical University from January 2006 to December 2019 were retrospectively analyzed. The acoustic parameters were compared between different subgroups. Kaplan-Meier method was used to calculate the overall survival (OS) and the recurrence-free rate (RFS), and univariate and multivariate Cox regression analyses were performed to determine the risk factors for postoperative recurrence. Results: A total of 150 PTC patients were enrolled in the final analysis, including 102 females and 48 males, with an average age of (53.5±13.7) years, and 62 patients (41.3%) aged over 55 years. There were 88 cases with stage Ⅰ, and 62 cases with stage Ⅲ. Fifty-five patients presented with preoperative vocal cord paralysis. There were 75 cases appearing adhesion between tumor or lymph node and recurrent laryngeal nerve while 75 cases presented with direct invasion. The comparisons of acoustic parameters showed that patients with RLN invasion had higher jitter compared with patients without RLN invasion [2.3% (1.4%, 3.2%) vs 1.8% (0.8%, 2.6%), P<0.001]. Moreover, patients with preoperative vocal cord paralysis (VCP) had higher jitter[3.1% (2.2%, 4.6%) vs 2.0% (1.1%, 2.8%), P<0.001] and shimmer [7.1% (4.9%, 9.9%) vs 5.5% (4.2%, 7.3%), P<0.001] and shorter maximum phonation time (MPT) [8.0 (6.0, 10.0) s vs 12.0 (10.0, 15.3) s, P<0.001] compared with patients without preoperative VCP. However, there was no statistical difference in acoustic parameters between cases with RLN adhesion and RLN invasion (all P>0.05). Postoperative follow-up time ranged between 12-196 months, with an average of (65.0±35.9) months. Sixteen patients (10.7%) had recurrence or metastasis, and 8 cases (5.3%) died of recurrence or metastasis. The 5-year OS rate was 95.1%, and the 10-year OS rate was 92.8%. The 5-year RFS rate was 88.9%, and the 10-year RFS rate was 86.2%. Univariate Cox analysis showed that age of onset ≥ 55 years, preoperative recurrent laryngeal nerve palsy, laryngeal, trachea or esophageal invasion were the risk factors for postoperative recurrence of PTC with RLN invasion (all P<0.05). Multivariate Cox analysis showed that age of onset ≥ 55 years (OR=1.060, 95%CI: 1.011-1.110, P=0.015) was an independent risk factor. Conclusions: Age of onset ≥ 55 years is an independent risk factor for postoperative recurrence in PTC patients with RLN invasion. Preoperative acoustic parameters may provide reference for evaluation of RLN function.

Abstract
Objective: To explore the possibility that the intestinal flora profile in complex anal fistula patients is different to that of healthy controls. This was assessed by sequencing of 16S rDNA in fecal samples from cohorts representing these populations. Methods: Fecal samples were collected from 30 complex anal fistula patients and 30 matched healthy controls. Patients were included if they met the diagnostic criteria of cryptoglandular anal fistula and had exhibited symptoms for more than 3 months. Complex anal fistula is diagnosed under the following circumstances: if the fistula in question spans 2/3 or more of the diameter of the anal sphincter; if there are more than two external orifices or fistula tracks; or if recurrence is observed after previous anal fistula surgery. Patients were excluded if there were comorbities including inflammatory bowel disease (as assessed by colonoscopy), chronic diarrhea, chronic constipation, diabetes, gastrointestinal malignancies, liver/ kidney dysfunction, or cognitive impairment. Patients whose anal fistulas were caused by Crohn's disease, trauma, special infections (such as actinomycosis and tuberculosis) were also excluded, as were those who had used antibiotics, prebiotics, or probiotics that may affect intestinal microecology in the month prior to the study. Total bacterial genomic DNA was extracted by PCR amplification of the V4 hypervariable region of the 16S rRNA sequences. High-throughput sequencing and data analysis were performed on the Illumina Miseq platform. Finally, operational taxonomic unit (OTU) clustering, alpha diversity and LEfSE data analysis were carried out. The larger the Chao or ACE index is, the higher the species abundance of the microflora is expected to be. Similarly, a smaller value for the Simpson index or a larger value for the Shannon index indicates greater microflora diversity. There was no statistically significant difference in gender, age, body mass index (BMI), drinking history, or smoking history between the two groups (P>0.05), indicating that they were comparable. Results: The α-diversity analysis including ACE, Chao, Shannon and Simpson indexes indicated a richer diversity of intestinal microflora in complex anal fistula patients than in healthy controls. In both patients and controls, OUT cluster analysis demonstrated that 93.4%±32.0% and 87.4%±41.2% of sequences were from Firmicutes and Bacteroidetes spp., respectively. On a genus level, samples from anal fistula patients showed a greater abundance of Prevotella spp. (4.9%±7.4% vs. 0.1%±1.1%, P<0.001), Megamonas (3.9%±8.2% vs. 0.5%±4.2%, P<0.05) and Lachnospira (2.6%±5.7% vs. 0.1%±3.4%, P<0.05), while showing a lesser abundance of Proteobacteria spp. (0.02%±4.2% vs. 9.3%±14.4%, P<0.01), Enterococcus (0.02%±2.3% vs. 9.3%±19.6%, P<0.05), Bacteroides (24.7%±9.9% vs. 29.8%±9.1%, P<0.05) and Klebsiella (0.4%±4.2% vs. 3.9%±7.3%, P<0.05) compared with healthy controls. Intestinal flora diversity in the complex anal fistula group was richer than in controls, as indicated by a higher ACE index (293.30±44.00 vs. 218.75±33.83, t=102.069, P<0.001), a higher Chao index (318.40±41.99 vs. 250.00±46.38, t=77.818, P=0.028), a higher Shannon index (3.36±0.29 vs. 2.43±0.34, t=9.657, P=0.001), and a lower Simpson index (0.103±0.013 vs. 0.131±0.013, t=5.551, P=0.046). LDA effect size analysis suggests that the main strains of Veillonellaceae, Selenemondales and Negativicutes, which all belong to the phylum Firmicutes, have the greatest influence on the above difference (LDA>4). Conclusions: The diversity of intestinal flora in patients with complex anal fistula is greater than in healthy controls, suggesting that these bacteria or their metabolites may be involved in the occurrence and development of anal fistulas.

Abstract
Objective: To investigate the treatment outcomes and risk factors of postoperative recurrence in T4a papillary thyroid carcinoma (PTC). Methods: A total of 185 patients with locally advanced T4a PTC treated in Beijing Tongren Hospital, Capital Medical University from January 2006 to December 2019 were retrospectively analyzed, including 127 females and 58 males, aged between 18 and 80 years, with 74 patients aged over 55 years. According to AJCC thyroid tumor staging, 111 cases were stage I (T4aN0M0 26 cases, T4aN1aM0 35 cases, and T4aN1bM0 50 cases) and 74 cases were stage Ⅲ (T4aN0M0 29 cases, T4aN1aM0 19 cases, and T4aN1bM0 26 cases). Kaplan-Meier method was used to calculate the overall survival and the recurrence-free rate, and univariate and multivariate logistic regression analyses on the clinical data were performed. Results: Recurrent laryngeal nerve invasion was observed in 150 cases, trachea invasion in 61 cases, esophagus invasion in 30 cases, and laryngeal structure invasion in 10 cases. Postoperative follow-up periods were 24-144 months, with an average of 68.29 months. Of the 185 patients, 18 (9.73%) had recurrences or metastases, including 9 cases (4.86%) died of recurrences or metastases. The 5-year and 10-year overall survival rates were respectively 95.21% and 93.10%. The 5-year and 10-year disease-free survival rates were respectively 89.65% and 86.85%. Univariate analysis showed that age of onset, tumor diameter, preoperative recurrent laryngeal nerve palsy, esophageal invasion and cervical lymph node metastasis were the risk factors for postoperative recurrence of T4a PTC(all P<0.05). Multivariate analysis showed that preoperative recurrent laryngeal nerve palsy (OR=3.27, 95%CI: 1.11-9.61, P=0.032) and lateral cervical lymph node metastasis (OR=4.71, 95%CI: 1.19-18.71, P=0.027) were independent risk factors for T4a PTC recurrence. Survival rate of patients with T4a PTC involving only the recurrent laryngeal nerve or the outer tracheal membrane was significantly better than that of patients with tracheal invasion (P<0.05). Conclusions: T4a PTC patients with R0 resection can still achieve good efficacy. Preoperative recurrent laryngeal nerve palsy and lateral cervical lymph node metastasis are independent risk factor for postoperative recurrence in the patients.

Abstract
Objective: To compare the outcomes of modified Appleby procedure and sub-adventitial divestment technique for locally advanced or borderline resectable pancreatic body cancer. Methods: A total of consecutive 58 patients(33 males and 25 females) who were diagnosed as locally advanced or borderline resectable pancreatic body cancer and underwent distal pancreatectomy at Pancreas Center, First Affiliated Hospital of Nanjing Medical University between September 2013 and May 2019 were retrospectively reviewed. The age(M(IQR)) was 62(9)years(range: 43 to 79 years). Thirty-one patients underwent distal pancreatectomy with celiac axis resection (DP-CAR) and 27 patients underwent distal pancreatectomy with sub-adventitial divestment technique(SDT). Perioperative parameters and follow-up data of these patients were analyzed. Quantitative data were compared with Wilcoxon test while categorical variables were compared with χ2 test or Fisher's exact test. Survival results were estimated by the Kaplan-Meier survival method with a Log-rank test. Results: There were no differences in age,gender,body mass index,abdominal symptoms,comorbidity or preoperative serum CA19-9 between two groups(all P>0.05). Obvious preoperative weight loss was more common in the group of SDT(48.1%(13/27) vs. 19.4%(6/31),χ²=5.431,P=0.020). Longer operative time(310(123) minutes vs. 254(137)minutes, Z=2.277,P=0.023),higher rate of combined organ resection(41.9%(13/31) vs. 14.8%(4/27),χ²=5.123,P=0.041) and longer postoperative hospital stay(15(10) days vs. 11(5)days,Z=2.292,P=0.022) were observed in the group of DP-CAR. Moreover,rate of overall morbidities was also higher (71.0%(22/31) vs. 29.6%(8/27),χ2=9.876,P=0.003),implicated by clinically relevant postoperative pancreatic fistula(61.3%(19/31) vs. 29.6%(8/27),χ2=5.814,P=0.020) in the DP-CAR group. Tumor size of the DP-CAR group was bigger(4.9(1.5)cm vs. 4.0(1.2)cm,Z=2.343,P=0.019) but no difference was seen between the DP-CAR group and SDT group in R0+R1(<1 mm) resection rate (84.0%(21/25) vs. 90.0%(18/20),P=0.678) and LNR(12.0(23.0)% vs. 9.0(18.0)%,Z=1.238,P=0.216),as well as median disease free survival(11.7 months vs. 11.4 months,Z=0.019,P=0.892) and median overall survival(16.3 months vs. 13.7 months,Z=0.172,P=0.679). Conclusions: Both DP-CAR and distal pancreatectomy with SDT are relatively safe and feasible for locally advanced or borderline resectable pancreatic body cancer. Compared with arterial resection,SDT may contribute to lower rates of postoperative complications and shorter duration of hospitalization,but no significant benefit is seen in long-term survival.

Abstract
Objective: To compare and analyze the clinical efficacy of pancreaticoduodenectomy for distal bile duct cancer and pancreatic head cancer. Methods: Clinical data of 1 005 patients who underwent pancreaticoduodenectomy and postoperative pathological examination confirmed the diagnosis of distal bile duct cancer and pancreatic head cancer at the Pancreas Center of the First Affiliated Hospital of Nanjing Medical University from January 2016 to December 2020 were analyzed retrospectively. There were 112 cases in the distal bile duct cancer group, 71 males and 41 females,with age (M(IQR)) of 65(15) years(range: 40 to 87 years); 893 cases in the pancreatic head cancer group, 534 males and 359 females,with age of 64(13)years(range: 16 to 91 years). The differences between clinicopathological characteristics and postoperative overall survival of the two groups were analyzed by χ2 test, Fisher's exact probability method, rank sum test or log-rank test, respectively. The difference in postoperative overall survival between the two groups was compared using Kaplan-Meier method after propensity score matching (1∶1). Results: Compared with the pancreatic head cancer group,the distal bile duct cancer group had shorter operative time (240.0(134.0) minutes vs. 261.0(97.0) minutes, Z=2.712, P=0.007),less proportion of combined venous resection (4.5% (5/112) vs. 19.4% (173/893), χ²=15.177,P<0.01),smaller tumor diameter (2.0(1.0) cm vs. 3.0(1.5) cm,Z=10.567,P<0.01),higher well/moderate differentiation ratio (51.4% (56/112) vs. 38.0% (337/893), χ²=7.328, P=0.007),fewer positive lymph nodes (0(1) vs. 1(3), Z=5.824, P<0.01),and higher R0 resection rate (77.7% (87/112) vs. 38.3%(342/893), χ²=64.399, P<0.01),but with a higher incidence of overall postoperative complications (50.0% (56/112) vs. 36.3% (324/892), χ²=7.913,P=0.005),postoperative pancreatic fistula (28.6% (32/112) vs. 13.9% (124/893), χ²=16.318,P<0.01),and postoperative abdominal infection (21.4% (24/112) vs. 8.6% (77/892), χ²=18.001,P<0.01). After propensity score matching, there was no statistical difference in postoperative overall survival time between patients in the distal bile duct cancer group and the pancreatic head cancer group (50.6 months vs. 35.1 months,Z=1.640,P=0.201),and multifactorial analysis showed that tumor site was not an independent risk factor affecting the prognosis of patients in both groups after matching (HR=0.73,95%CI:0.43 to 1.23,P=0.238). Conclusions: Patients with distal bile duct cancer are more likely to benefit from early diagnosis and surgical treatment than patients with pancreatic head cancer,but with a relative higher postoperative complication rates. The different tumor origin site is not an independent risk factor for prognosis of patients with distal bile duct cancer and pancreatic head cancer after propensity score matching.

Abstract
Objective: To clarify the effect of high-frequency repetitive transcranial magnetic stimulation (rTMS) on cognitive function in cerebral ischemic rats, and to explore its underlying mechanism by RNA sequencing. Methods: Thirty male Sprague-Dawley (SD) rats underwent transient middle cerebral artery occlusion (tMCAO). According to the Bederson score, 10 rats with a score of 1-3 were excluded, and the remaining 20 rats were then randomly divided into the tMCAO group (n=10) and the rTMS group (n=10). Meanwhile, 10 rats with sham operation were assigned to the sham group (n=10). Rats in the rTMS group received 20 Hz rTMS from day 7 to day 28 after surgery. From day 28 to day 33 after the operation, Morris water maze test was performed to detect the cognitive function of rats in each group. The cortical tissues around the infarcts from the rTMS tMCAO groups were taken for RNA sequencing analysis, with 3 rats in each group. Results: The escape latency of rats in the rTMS group[ (53±4)s] and the group [(51±5)s] were significantly shorter than that of the tMCAO group[ (58±4)s, P<0.05)]. The times that the rats crossed the original platform in 60 seconds in the rTMS group[2.5 (1.5-3.0)] and sham group[3.0 (1.5-3.0)] were more than that of the tMCAO group [1.0(0.5-1.5)] (P<0.05). RNA sequencing detected 16 significantly differentially expressed genes, including 9 up-regulated genes and 7 down-regulated genes. GO analysis showed that the functions of up-regulated genes were mainly concentrated in the processes of chemical homeostasis and cell metal ion homeostasis. While the functions of down-regulated genes mainly enriched in the inflammatory response. Conclusion: Twenty Hz rTMS can improve the cognitive function of rats with cerebral infarction, and its underlying mechanism may be related to maintaining chemical and metal ion homeostasis and regulating the polarization of microglia to reduce neuroinflammation.

Abstract
Objective: To investigate the clinical characteristics of adult undifferentiated embryonal sarcoma of the liver (UESL). Methods: A retrospective analysis was performed on the clinical data of 5 patients with UESL who underwent surgical resection and were pathologically confirmed from January 2005 to December 2020 at the First and the Second Affiliated Hospital of Anhui Medical University. All the patients were female aged from 49 to 77 years old. Preoperative CT showed a solid cystic mass with low density and a slight density of cord like septum. Imaging findings were misdiagnosed as hepatocellular carcinoma or cystadenocarcinoma. CA125 was higher in 3 patients,and AFP in all patients was normal. Results: All patients were treated by surgery. The mean diameter of tumor was 20.2 cm (range:15.0 to 30.0 cm). All five patients had vimentin expression in immunohistochemistry. Three cases underwent complete resection of the tumor and achieved R0 resection,2 of them had tumor free survival until the end of the follow-up (89 and 55 months),the other 1 case died from renal cell carcinoma 158 months later. The remaining 2 cases were radically resected,but the tumors were ruptured during operation,and relapsed after 2 months and 19 months respectively. The overall survival was 3 and 26 months respectively. Conclusions: Radical hepatectomy is the first choice for treatment of UESL. Intraoperative tumor rupture should be avoided and implant metastasis is a major factor affecting the prognosis of UESL.

Abstract
Objective: To evaluate the value of left-sided uncinate process first approach in pancreaticoduodenectomy. Methods: The clinical data of 152 patients who underwent the left-sided uncinate process first approach during pancreaticoduodenectomy at Pancreas Center, the First Affiliated Hospital of Nanjing Medical University from January 2020 to December 2020 were analyzed retrospectively. There were 64 females and 88 males,with age(M(QR)) of 62.0(14.7)years(range:16.0 to 84.0 years). The clinical date of 117 patients who underwent pancreaticoduodenectomy without using left-sided uncinate process first approach in the same period was selected as the control group,including 65 females and 52 males,with age of 64.0(13.0) years(range:13.0 to 84.0 years). Fisher exact probability method and t test were used to compare the data between the two groups,rank sum test was used for comparison of continuous variables between the two groups. Results: Pancreaticoduodenectomy was successfully performed in 152 patients in left-sided uncinate process first approach group. The operation time was 222.5(77.0) minutes(range:117.0 to 480.0 minutes),the time of uncinate process resection from left-side(the time from jejunum dissection to complete dissociation of the uncinate process) was 11.0(4.5) minutes(range:7.5 to 20.0 minutes),the time of pancreatic head resection (the time from jejunum dissection to pancreaticoduodenal specimen removal) was 26.0(8.5) minutes(range:20.0 to 41.0 minutes),the intraoperative blood loss was 200(150) ml(range:50 to 800 ml),and the intraoperative blood transfusion rate was 9.2% (14/152). Postoperative conditions:The postoperative hospital stay was 12 (9) d(range:6 to 55 d),the overall incidence of postoperative complications was 59.9%(91/152),and there was no perioperative death. Pathological results:The R0 resection rate of periampullary malignant tumor was 64.3%(77/112),with negative rate of uncinate process margin was 91.1%(102/112). The R0 resection rate of pancreatic ductal adenocarcinoma was 46.9%,with negative rate of uncinate process margin was 89.1%(57/64). Compared with the non-left-sided uncinate process first approach group(222.5(77.0) minutes, 9.2%(14/152)),the left-sided uncinate process first approach group had shorter operation time(246.0(94.0) minutes) (Z=3.964,P<0.01),less intraoperative blood loss (18.8%(22/117))(Z=4.843,P<0.01),and lower intraoperative blood transfusion rate(χ²=5.248,P=0.029). However,there were no significant differences between two groups in postoperative hospital stay(Z=1.682,P=0.093),postoperative overall complications(P=0.549),R0 resection rate of periampullary malignant tumor(χ²=2.012,P=0.156),and negative rate of uncinate process margin(χ²=2.108,P=0.147). Conclusions: The "left-sided uncinate process first approach" could completely resect uncinate process under a direct vision,especially when the uncinate process was behind the superior mesenteric artery or beyond the left lateral margin of the superior mesenteric artery. The "left-sided uncinate process first approach" might increase the negative rate of uncinate process margin and R0 resection rate for periampullary malignant tumor.

Abstract
BACKGROUND Mechanical circulatory support (MCS) is increasingly being used as a bridge to transplant in pediatric patients. We compare outcomes in pediatric patients bridged to transplant with MCS from an international cohort. METHODS This retrospective cohort study of heart-transplant patients reported to the International Society for Heart and Lung Transplantation (ISHLT) registry from 2005-2017 includes 5,095 patients <18 years. Pretransplant MCS exposure and anatomic diagnosis were derived. Outcomes included mortality, renal failure, and stroke. RESULTS 26% of patients received MCS prior to transplant: 240 (4.7%) on extracorporeal membrane oxygenation (ECMO), 1,030 (20.2%) on ventricular assist device (VAD), and 54 (1%) both. 29% of patients were <1 year, and 43.8% had congenital heart disease (CHD). After adjusting for clinical characteristics, compared to no-MCS and VAD, ECMO had higher mortality during their transplant hospitalization [OR 3.97 & 2.55; 95% CI 2.43-6.49 & 1.42-4.60] while VAD mortality was similar [OR 1.55; CI 0.99-2.45]. Outcomes of ECMO+VAD were similar to ECMO alone, including increased mortality during transplant hospitalization compared to no-MCS [OR 4.74; CI 1.81-12.36]. Patients with CHD on ECMO had increased 1 year, and 10 year mortality [HR 2.36; CI 1.65-3.39], [HR 1.82; CI 1.33-2.49]; there was no difference in survival in dilated cardiomyopathy (DCM) patients based on pretransplant MCS status. CONCLUSION Survival in CHD and DCM is similar in patients with no MCS or VAD prior to transplant, while pretransplant ECMO use is strongly associated with mortality after transplant particularly in children with CHD. In children with DCM, long term survival was equivalent regardless of MCS status.

Abstract
Abstract Objective To explore a kind of visual evoked potential test equipment and method that is more suitable for the application of forensic clinical visual acuity evaluation. Methods Thirty-four volunteers (68 eyes) were selected, including 15 males and 19 females, aged between 20 and 40 years. Test lenses were placed before the tested eyes of volunteers to induce refractive myopia with insert method, and the diopter lenses were adjusted so that the visual acuity level of one eye of volunteers was above 0.8, and the visual acuity of the other eye was at moderate damage level (<0.3 and ≥0.1). The tests were carried out under the binocular simultaneous asynchronous stimulation mode (hereinafter referred to as "binocular mode") and monocular separate stimulation mode (hereinafter referred to as "monocular mode") of virtual reality-pattern visual evoked potential (VR-PVEP), and the amplitude of PVEP of volunteers under the two modes was compared at four spatial frequencies of 8×8, 16×16, 24×24 and 32×32. Results The differences in the amplitude of P100 wave between monocular and binocular modes at 8×8 spatial frequency had no statistical significance and the differences in amplitude of P100 wave between monocular and binocular modes at 16×16, 24×24, and 32×32 spatial frequencies had statistical significance (P<0.05). The amplitude of the same eye in monocular mode was higher than that in binocular mode. Through correlation analysis, it was found that the amplitude of P100 wave in monocular mode was moderately correlated with amplitude of P100 wave in binocular mode. Conclusion In forensic identification practice, VR-PVEP is helpful for overcoming the disturbance of poor fixation, and to increase the reliability of PVEP evaluation results. It can greatly shorten the detection time of PVEP and improve work efficiency.

Abstract
Objective: To investigate the value of conventional magnetic resonance imaging (MRI) based radiomic model in predicting the texture of pituitary macroadenoma. Methods: The complete data of 101 patients with pituitary macroadenoma confirmed by surgery and pathology in Yijishan Hospital of Wannan Medical College from December 2014 to December 2019 were retrospectively analyzed. According to the texture of the intraoperative pituitary tumor, patients were divided into soft group (n=58) and hard group (n=43). They were randomly divided into training group (n=72) and validation group (n=29) at a ratio of 7∶3. All patients underwent conventional MRI scan of the pituitary gland. Itk-snap software was used to manually outline the T(1)-weighted image (T(1)WI), T(2)-weighted image (T(2)WI) and enhanced T(1)WI image section by section on tumor area of interest (ROI) and perform three-dimensional fusion. Then AK software was imported to extract texture features. The regression analysis methods of minimum redundancy maximum relevance (mRMR) and least absolute shrinkage and selection operator (LASSO) were used for feature selection and radiomic signature establishment. The reliability of the model was verified by 100 leave-group-out cross validation (LGOCV), and the predictive ability of the model was evaluated by drawing the receiver operating characteristic (ROC) curve. The decision curve analysis (DCA) was used to evaluate the clinical application value of the model. Results: The AUC (Area Under the ROC Curve) (95%CI) values of T1WI, T2WI, enhanced T1WI, and the combined sequence model to predict the texture of pituitary macroadenomas in the training and validation groups were 0.91 (0.84-0.98) and 0.90 (0.78-1.00), 0.86 (0.78-0.95) and 0.83 (0.64-1.00), 0.90 (0.83-0.97) and 0.89 (0.77-1.00),0.92 (0.85-0.98) and 0.91 (0.79-1.00), respectively. DCA demonstrated that T(1)WI, T(2)WI, enhanced T(1)WI, and combined sequence model all had good net benefits in clinical practice. Conclusions: T(1)WI, T(2)WI, enhanced T(1)WI, and combined sequence model of conventional MRI all had high efficacy in predicting the texture of pituitary macroadenoma, which provided a new quantitative method for predicting the texture of pituitary macroadenoma.

Abstract
Objective: To explore influence on physical development of children aged 18 months from HIV-positive mothers for prevention mother to child transmission of HIV (PMTCT) in Guangxi Zhuang autonomous region, and provide evidence for the improvement PMTCT program. Methods: This retrospective case control study was conducted in 554 HIV negative infants aged 18 months whose HIV positive mothers had received PMTCT services reported through PMTCT system database from January 1, 2010 to December 31, 2017 and 1 109 healthy infants born in 2017, whose mothers were healthy, in Lingshan, Luzhai, and Hengxian counties, ranking top three counties with high HIV infection prevalence, in Guangxi. PMTCT data and physical development data such as height, weight and head circumference of children aged 18 months were collected. The physical dysplasia in the infants was defined as at least one of the three main indicators of height, weight and head circumference below the normal range. Results: The number of HIV-positive mother and their infants in the case group were 667 and 554 respectively, and the PMTCT rates were 91.15% (608/667) and 96.57% (535/554) respectively. HIV positive rate, mortality rate and mother to child transmission rate of the infants aged 18 months were 1.44% (8/554), 3.07% (17/554) and 1.91% (8/418) respectively, and the physical examination results of the infants aged 18 months showed that the physical dysplasia rate was 30.51% (169/554). Among the 1 109 infants in the control group, the physical dysplasia rate was 9.83% (109/1 109). The difference between the case group and the control group was significant (P<0.01). Conclusion: The PMTCT rates of HIV positive mother and their children were more than 90.00%, respectively. However, poor physical development rate of infants aged 18 months were more than 30.00%. The possible influence of PMTCT on physical development of the infants aged 18 months of HIV positive mother's needs to be further studied.

Abstract
Objective:To investigate the effect of vestibular rehabilitation exercise combined with manual reduction in the treatment of benign paroxysmal positional vertigo(BPPV). Method:A total of 186 patients with benign paroxysmal positional vertigo were selected and randomly divided into experimental group and control group . The control group was treated with manual reduction, while the experimental group was treated with manual reduction combined with vestibular rehabilitation exercises. Patients with posterior semicircular canal BPPV carried out Brandt-Daroff exercises, while patients with horizontal semicircular canal BPPV carried out Cawthorne-Cooksey exercises and position restriction. To analyze the clinical curative effect, DHI score, residual dizziness and recurrence of the two groups. Result:There was no significant difference in total efficiency rate and DHI score between the two groups at the first diagnosis(P>0.05). After 1 week, 2 weeks and 1 month of follow-up, the total efficiency rate of the experimental group were 90.3%, 91.4% and 93.5% respectively, which were significantly higher than those of the control group(P<0.05). Synchronously, the scores of DHI in experimental group were respectively 14.33±5.71, 12.25±4.98 and 9.45±3.70, which were significantly lower than the control group(P<0.05). For the experimental group, in the first diagnosis, 1 week, 2 weeks and 1 month after follow-up, residual dizziness patients were 29 cases, 13 cases, 8 cases and 0 cases. The mean duration of residual dizziness was (5.86±4.71) days, which was significantly lower than that in the control group(P<0.05). One month after follow-up, the recurrence of patients in the experimental group were 5 cases, while the control group were 11 cases, significant difference between the two groups(χ²=4.704, P=0.030). Conclusion:Manual reduction combined with vestibular rehabilitation exercise can significantly improve the therapeutic effect of BPPV, ameliorate the residual dizziness symptoms and reduce the recurrence rate, meanwhile improve the balance function and quality life of patients.

Abstract
Objective: To examine the short-term outcomes of minimally invasive reoperation for severe tricuspid regurgitation after left-sided valve surgery. Methods: From January 2015 to December 2018, a total of 89 patients with severe tricuspid regurgitation after left-sided valve surgery received reoperation in Department of Cardiovascular Surgery, Zhongshan Hospital, Fudan University were included in this study. There were 21 males and 68 females, aging of (56.4±7.9) years (range: 41 to 74 years). The interval between previous left-sided valve surgery and tricuspid reoperation was (14.1±6.1) years (range: 4 to 33 years). A combination of multiple minimally invasive techniques were adopted, including endoscopy-assist right minithoracotomy approach, peripheral cannulation strategy with the vacuum-assist single venous drainage technique, heart beating technique, and temporary percutaneous pacemaker implantation, with a concomitant enhancement in preoperative right cardiac function optimization. Results: All patients received minimally invasive isolated tricuspid valve replacement (n=81) or tricuspid valve repair (n=8). After the application of multiple minimally invasive techniques, the operative mortality rate was only 3.4% (3/89). The causes of death were progressive right heart failure with multiorgan failure (n=1) and low cardiac output associated with postoperative bleeding (n=2). Regarding to the perioperative complications, renal replacement therapy rate was 5.6% (5/89), permanent pacemaker implantation rate was 1.1% (1/89), and the incidence of stroke was 0. Mechanical ventilation time was 24(24) hours, ICU stay time was 2.5 (3.0) days (M(Q(R))). During the short-term follow-up, there were no case of severe tricuspid regurgitation, 2 cases of moderate regurgitation, 4 cases of mild-to-moderate regurgitation. Conclusions: For severe tricuspid regurgitation after left-sided valve surgery, the advanced minimally invasive techniques can significantly reduce the operative mortality and morbidity. Minimally invasive bioprosthetic tricuspid valve replacement is a reliable alternative for severe tricuspid regurgitation after left-sided valve surgery.

Abstract
Late tricuspid regurgitation after left-sided valve surgery can negatively affect long-term prognosis. The surgical timing and strategy of tricuspid valve reoperation will have important impact on the surgical outcomes. However, there is no clear recommendations of the surgical timing for this condition in the current guidelines. Generally, tricuspid valve reoperation should be performed before irreversible right heart failure occurs. Although tricuspid valve repair is the first choice for tricuspid regurgitation, bioprosthetic tricuspid valve replacement might be a reliable alternative when tricuspid leaflets have severe rheumatic damage or right ventricle and tricuspid annulus significantly dilate. Combined minimally invasive surgical techniques, including right minithoracotomy approach, accessing the right atrium directly through the pericardium with limited dissection, peripheral cannulation strategy with the vacuum-assist single venous drainage technique and heart beating technique, can significantly decrease the operative mortality and postoperative bleeding. With development of interventional therapy, transcatheter tricuspid valve repair or replacement may become alternatives for tricuspid regurgitation after left-sided valve surgery in the future.

Abstract
Objective: To investigate the changes of perioperative immune index in patients with breast cancer and its clinical significance. Methods: Th1 cells, Th2 cells, Th1/Th2 ratio and regulatory T cells (Treg) were detected in peripheral blood of 103 patients with primary breast cancer and 116 patients with breast fibroma before surgery and on the 1st, 3rd and 5th day following operation. The relationship of changes in T lymphocyte subsets and clinicopathological characteristics, as well as tumor-free survival of breast cancer patients, was analyzed. Results: The levels of Th1 cells in breast cancer group on the 1st, 3rd and 5th day following operation were (12.20±0.45)%, (13.89±0.47)%, (14.04±0.49)%, which were significantly lower than those before operation [(15.82 + 0.51)%, all P<0.05 ]. Treg cells, however, with the number of (3.82±0.13)%, (3.25±0.11)%, (2.95 ±0.11)%, were remarkably higher than those before operation [(2.53 ±0.11)%, all P<0.05]. With respect to breast fibroma patients, there was no significant difference compared with those before operation of Th1 cells, Th2 cells and Treg cells (all P>0.05). The changes of Th1 cells were associated with the degree of differentiation, T stage, N stage, TNM stage, HER-2 status and Ki-67 (all P<0.05). Treg cells were related to T stage, N stage and HER-2 status (all P<0.05). Tumor-free survival in the Th1-cell-increasing group was significantly better than that in the Th1-cell-decreasing group (P=0.045), while cell-decreasing group of Treg showed the improved outcomes (P=0.012). Conclusions: The levels of Th1 cells and Treg cells are important indicators of cellular immune function in patients with breast cancer. Moreover, the perioperative changes of Th1 cells and Treg cells are associated with the size of tumors, pathological parameters, clinical stages and tumor-free survival outcomes.

Abstract
BACKGROUND Blepharophimosis syndrome (BPES) is characterized by eyelid malformation with occasional premature ovarian failure. Mutations in FOXL2 underlie a fraction of BPES cases. OBJECTIVE We aimed to investigate the genetic basis of BPES in 26 Chinese families that included 78 patients. METHODS We performed ophthalmological examinations on each family member. We used Sanger sequencing to screen FOXL2 exons and their flanking sequences. We also performed bioinformatics studies, structural modeling and pathogenicity evaluations on all identified variations. Literature was reviewed and genotype-phenotype correlation analysis was performed. RESULTS The patients had typical manifestations of BPES. Ten mutations were identified in ten of the twenty-six families. Among these, seven were novel mutations. These included the six truncating mutations, p.Glu69*, p.Gly256Glyfs*14, p.Ala14Serfs*135, p.Pro333Profs*200, p.Pro290Leufs*70, and p.Pro157Profs*91, and one missense mutation, p.Tyr59Cys. The mutations were scattered within the gene, and no mutational hotspots were found. Genotype-phenotype correlation analysis showed that frameshift or nonsense mutations were correlated with type I BPES, while in-frame or missense mutations were associated with type II BPES. CONCLUSION We report the largest BPES cohort in China thus far as well as seven novel mutations in FOXL2. The identification of novel mutations has not only expanded the mutational spectrum of the gene (which is valuable for mutation detection-based screening) but also suggests that most mutations within the Chinese population may not have been characterized yet.

Abstract
Abstract Objective To research the correlation between the visual acuity ratio and pattern reversal visual evoked potential (PRVEP) P100 waveform amplitude ratio of both eyes. Methods Forty-seven volunteers were selected, and the visual chart visual acuity of both eyes was measured. The visual acuity ratio of the eye with poor vision to the eye with better vision was calculated by five grade notation method. The amplitudes of P100 waveforms of both eyes were recorded respectively by using black-and-white checkerboard PRVEP and chosing 1°, 15' stimulating visual angle, and the ratio of amplitudes between the two eyes was also calculated. SPSS 20.0 software was used to analyze the correlation between the visual acuity ratio and the ratio of P100 waveform amplitudes between the two eyes. Return test and linear regression analysis with the binocular ratio of P100 waveform amplitudes as the independent variable (x) and the binocular visual acuity ratio as the dependent variable (y) were made. Results There was a positive correlation between the binocular visual acuity ratio and the ratio of P100 waveform amplitudes under 15' stimulating visual angle (Pearson correlation coefficient was 0.62, P=0.000). The fitting linear regression equation was y=0.090 x+0.846 (F=20.954, P=0.000). There was no significant correlation between the binocular ratio of visual acuity and the binocular ratio of P100 waveform amplitudes under 1° stimulating visual angle (P>0.05). Results of return test showed that there was no statistical significance in the difference between visual acuity estimated by equation and actual detected visual acuity. Conclusion In forensic appraisal of monocular injury, fitting linear regression equation of binocular visual acuity ratio and the binocular ratio of P100 waveform amplitudes under 15' stimulating visual angle, is helpful for visual acuity level estimation of the injured eye to some extent.

Abstract
Objective: To observe the histopathological features of different opportunistic infections and tumors of the intestinal mucosa in AIDS patients, and to explore the correlation between different lesions and CD4+ T lymphocyte levels. Methods: Colonic mucosal biopsy specimens of 263 patients with clinically diagnosed AIDS and abdominal pain, diarrhea, blood in the stool and other gastrointestinal symptoms were collected from Beijing Ditan Hospital from 2010 to 2018. There were 232 males and 31 females, with age range 10-81 (mean 40±13) years. HE staining, histochemical special staining, immunohistochemical staining, and in-situ hybridization were used to detect the expression of different opportunistic infection pathogens, tumors and CD4+ T lymphocytes. Peripheral blood was also taken for CD4+ T lymphocytes, CD8+ T lymphocytes, HIV viral load and routine indicators. Results: The cohort included 263 intestinal mucosal biopsy specimens. There were 175 cases (66.5%) of non-specific inflammation, and pathogens were detected in 41 cases (15.6%), including 20 cases(7.6%) of cytomegalovirus (CMV) infection, 12 cases (4.6%) of mycobacterial infection, eight cases (3.0%) of amoeba infestation, and one case (0.3%) of talaromycesmarneffei infection; there were also 41 (15.6%) neoplastic lesions including 25 cases (9.5%) of intraepithelial neoplasia, 10 cases (3.8%) of adenocarcinoma and squamous cell carcinoma, six cases (2.3%) of lymphoma; and six cases (2.3%) of ulcerative colitis. The peripheral blood CD4+T lymphocyte levels of patients with CMV, mycobacteria and talaromycesmarneffei were less than 200/μL; the peripheral blood CD4+ T lymphocyte level (P<0.01) and intestinal mucosa CD4+T lymphocytes (P<0.01) were all significantly lower than those in patients with non-specific inflammation. The peripheral red blood cells and hemoglobin levels of patients with CMV and mycobacterial infection (P<0.01), adenocarcinoma and squamous cell carcinoma (P<0.05) were significantly lower than those of non-specific inflammation patients. Conclusions: Pathologic examination of intestinal mucosa can identify specific infections and neoplastic lesions in AIDS patients; the most common lesions are non-specific inflammation, and CMV infection is the most common opportunistic infections; CMV, mycobacteria and talaromycesmarneffei infections are associated with decreased levels of CD4+ T lymphocytes in peripheral blood and intestinal mucosa; entamoeba histolytica infestation and non-HIV-related neoplastic lesions such as intraepithelial neoplasia, adenocarcinoma and squamous cell carcinoma are not associated with changes in AIDS immune function.

Abstract
X-ray absorption spectroscopy (XAS) is performed to study changes in the electronic structures of colossal magnetoresistance (CMR) and charged ordered (CO) La1-x Ca x MnO3 manganites with respect to temperature. The pre-edge features in O and Mn K-edge XAS spectra, which are highly sensitive to the local distortion of MnO6 octahedral, exhibit contrasting temperature dependence between CMR and CO samples. The seemingly counter-intuitive XAS temperature dependence can be reconciled in the context of polarons. These results help identify the most relevant orbital states associated with polarons and highlight the crucial role played by polarons in understanding the electronic structures of manganites.

Abstract
OBJECTIVES To explore the assessment method of original height of L1-2 after vertebral compression fracture and its application value in forensic clinical practice. METHODS A total of 154 normal thoracic and lumbar X-ray films were collected, and 140 cases were used as experimental group while 14 cases as validation group. The heights of anterior (Ha) and posterior (Hp) vertebral body of T₁₂-L₃ vertebrae in each X-ray image were measured. In the experimental group, the correlation analysis between HaL₁ and HaT₁₂, HpT₁₂, HpL₁, HaL₂ and HpL₂ was carried out, and regression equation was established via fitting. The correlation analysis between HaL₂ and HaL₁, HpL₁, HpL₂, HaL₃, HpL₃ was performed, and the regression equation was also established via fitting. The difference between the predicted and measured values of HaL₁ and HaL₂ in validation group was compared. RESULTS In the 140 normal subjects, HaL₁ (y₁) was well correlated with HaT₁₂ (x₁) and HaL₂(x₂), and the multiple linear regression equation was y₁=2.545+0.423 x₁+0.486 x₂ (determining coefficient R²=0.712, P<0.05; F=169.206, P<0.05). There was no significant difference between the predicted and actual measured values of HaL₁ in the validation group ( P>0.05). HaL₂ (y₂) was well correlated with HaL₁ (x₃) and HaL₃ (x₄), and the multiple linear regression equation was y₂=4.354+0.530 x₃+0.349 x₄ (determining coefficient R²=0.689, P<0.05; F=151.575, P<0.05). There was no significant difference between the predicted and actual measured values of HaL₂ in the validation group ( P>0.05). CONCLUSIONS It is more appropriate to evaluate the original height of L₁ or L₂ single vertebrae by comparing with the height of the anterior edge of the upper and lower adjacent vertebral bodies.

Abstract
We present magnetic susceptibility, heat capacity, and neutron diffraction measurements of polycrystalline Nd2Ru2O7 down to 0.4 K. Three anomalies in the magnetic susceptibility measurements at 146, 21 and 1.8 K are associated with an antiferromagnetic ordering of the Ru4+ moments, a weak ferromagnetic signal attributed to a canting of the Ru4+ and Nd3+ moments, and a long-range-ordering of the Nd3+ moments, respectively. The long-range order of the Nd3+ moments was observed in all the measurements, indicating that the ground state of the compound is not a spin glass. The magnetic entropy of Rln2 accumulated up to 5 K, suggests the Nd3+ has a doublet ground state. Lattice distortions accompany the transitions, as revealed by neutron diffraction measurements, and in agreement with earlier synchrotron x-ray studies. The magnetic moment of the Nd3+ ion at 0.4 K is estimated to be 1.54(2)µ B and the magnetic structure is all-in all-out as determined by our neutron diffraction measurements.

Abstract
Binocular vision refers to a progress of analysing and integrating the binocular visual signals into a whole and three-dimensional sensory perception by higher nerve centre. In this process, the interac- tion between the two eyes results in the changes of output signal, which is called binocular interaction. Through a series of subjective and objective experiments, it can be concluded that binocular interaction can be divided into three types: facilitation, summation and suppression, and the forms of binocular interaction in different visual states are different. In general, the visual signal is processed by binocular interaction, so that there are some differences between binocular vision and monocular vision. The extent of the difference can be affected by the damage of monocular vision and then affects the binocular vision. Thus, it is necessary for forensic scientists to further study the effects of the monocular visual impairment on visual function. Based on relevant data, this paper reviews the mechanism of the monocular visual impairment in binocular vision, the research methods and the application prospect in forensic science.

Abstract
Objective: To evaluate risk factors for delayed gastric emptying(DGE)following pancreaticoduodenectomy(PD). Methods: There were 492 consecutive patients who underwent PD in Pancreas Center, the First Affiliated Hospital with Nanjing Medical University between January 2012 and December 2014 were identified from a prospective database.There were 315 male and 177 female patients with a median age of 60.5 years.Univariate and multivariate analyses were performed to investigate the independent risk factors for clinically relevant DGE(CR-DGE). Results: The overall incidence of DGE was 29.5%, with Grade B and C occurring at 4.3% and 5.9%, respectively.In multivariate analysis, pancreatic duct diameter less than 3 mm(OR=1.888, P=0.042), pylorus-preserving pancreaticoduodenectomy(OR=2.627, P=0.005) and clinically relevant postoperative pancreatic fistula(OR=2.740, P=0.007) were independently associated with CR-DGE.Other main complications such as postoperative pancreatic fistula, pyoperitoneum, intraabdominal infection were also associated with the severity of DGE(χ(2)=21.360, 14.422, 14.378; P=0.011, 0.002, 0.002). DGE patients had a significantly prolonged postoperative length of stay(31(24-41)d vs. 13(11-17)d) and increased medical cost((122 367.5±66 068.3)yuan vs. (78 200.7±27 043.9)yuan)(both P<0.01). Conclusions: Small pancreatic duct, underwent pylorus-preserving pancreaticoduodenectomy and suffered postoperative pancreatic fistula might indicate a high risk of CR-DGE.

Abstract
OBJECTIVES To study the characteristic of contrast visual evoked potentials (CVEP) in patients with ocular trauma. METHODS Sixty patients defined as ocular trauma by forensic clinical examination in our center were selected, and split into 0.2-0.3 (Group A), 0.3-0.5 (Group B) and ≥0.5 (Group C) according to the best corrected visual acuity. The variation characteristics of wave amplitude and latency of CVEP under 100%, 25% and 10% contrast were observed and analyzed statistically. RESULTS (1) Under the same contrast, the wave amplitude of P₁₀₀ decreased with the decrease of stimulus perspective. (2) Under the same stimulus perspective, the wave amplitude of P₁₀₀ decreased with the decrease of contrast (P<0.05). (3) Under the contrast of 100% and 25% with the same stimulus perspective (except 100% 7' perspective stimulus), the difference between group A and group B had no statistical significance (P>0.05). Between group A and group C, group B and group C, the wave amplitude of P₁₀₀ gradually increased with the increase of vision (P<0.05). Under the contrast of 10% with 15' stimulus perspective, the wave amplitude of P₁₀₀ increased with the increase of vision (P<0.05). (4) Under the same contrast with the same stimulation perspective, the latency of P₁₀₀ wave shortened with the increase of vision, while the difference had no statistical significance (P>0.05). Under the same stimulus perspective, the latency of P₁₀₀ wave was prolonged with the decrease of contrast (P>0.05). CONCLUSIONS CVEP may become one of the possible methods for the evaluation of contrast visual acuity.

Abstract
OBJECTIVES To compare the differences between Hertel exophthalmometry and CT on exophthalmos measurement, and explore its practical application value in forensic medicine. METHODS Fifty-six normal individuals without eye injuries or diseases were selected as the control group. The absolute values of exophthalmos were measured in the standardized CT image workstation. The difference of binocular exophthalmos was compared in normal group. Forty-seven cases with unilateral orbital fracture were divided into injured eye group and normal eye group according to the presence of binocular orbital fractures. The differences of the absolute values of eophthalmos from the same eye and the relative values of eophthalmos between two eyes for same person measured by Hertel exophthalmometry and CT were analyzed. RESULTS There was no statistical difference of exophthalmos between the normal eyes measured by CT method. In the normal eye group, the absolute value of exophthalmos measured by CT method was (16.66±5.41) mm, which was (16.16±4.45) mm when measured by the Hertel exophthalmometry method. There was no statistical difference between two groups (P>0.05). In the injured eye group, there was statistical difference between the absolute values of exophthalmos measured by two measurement methods ( P<0.05). There was no statistical difference of the relative values of exophthalmos between the injured eyes and the normal eyes by two measurement methods (P>0.05). CONCLUSIONS CT method has a good consistency with Hertel exophthalmometry, which can be applied into the practice of medicolegal expertise.

Abstract
Objective: The Notch signaling pathway is closely related to biliary fibrosis. Previous studies have shown that Astragaloside (AS) can prevent the progression of cholestatic liver fibrosis. The purpose of this study is to observe the effect of AS on the regulation of Notch signaling pathway in biliary fibrosis. Methods: Cholestatic liver fibrosis was established by common bile duct ligation (BDL) in rats. Two weeks after BDL, the rats were randomly divided into a model group (i.e., BDL), an Astragalosides group (AS), and a sorafenib (SORA) positive control group and treated for 3 weeks. Bile duct proliferation and liver fibrosis were determined by tissue staining. Protein and gene expression were determined by immunostaining, immunoblotting and RT-PCR, respectively. Activation of the Notch signaling pathway was evaluated by analyzing expressions of Notch-1, -2, -3, -4, Jagged (JAG)1, Delta like (DLL)-1, -3, -4, Hes1, Numb and RBP-Jκ. Statistical analysis of variance analysis, q test, P < 0.05 showed that the difference was statistically significant. Results: (1) AS significantly reduced the deposition of collagen and the Hyp content of liver tissue (500.15 ± 86.10 vs. 625.72 ± 105.62, P = 0.031), and inhibited the activation of hepatic stellate cells. (2) AS significantly decreased the protein and mRNA expressions of transforming growth factor (TGF)-β1 (1.02±0.15 vs. 1.89±0.36, P = 0.007; 1.17±0.18 vs. 1.68±0.29, P = 0.013, respectively) and α-smooth muscle actin (α-SMA, 0.41±0.11 vs. 0.72±0.16, P = 0.003; 1.71±0.57 vs. 2.68±0.46, P = 0.008, respectively) compared with BDL group. In contrast, AS significantly enhanced expression of the Smad 7 protein compared with the BDL group (0.72±0.008 vs. 0.33±0.001, P = 0.005). AS also reduced biliary epithelial cell proliferation. AS reduced the mRNA levels of CK7, CK8 and CK18 (1.31±0.39 vs. 2.63±0.82, P = 0.009; 0.71±0.09 vs. 0.87±0.08, P = 0.031; 2.56±0.32 vs. 3.41±0.39, P = 0.010, respectively) and reduced the positive areas of CK19 and OV6 (62 337.17±21 873.38 vs. 22 5472.67±26 933.63, P = 0.000; 92 237.43±15 894.11 vs. 171 298.13±61 761.37, P = 0.000, respectively). (3) The mRNA expression of Notch-2, -3, -4 and JAG1 were significantly reduced in the AS group compared to the BDL group (1.07±0.19 vs. 1.51±0.28, P = 0.044; 0.99±0.24 vs. 1.18±0.10, P = 0.043; 1.36±0.42 vs. 3.40±0.44, P = 0.048; 2.62±0.43 vs. 3.73±0.83, P = 0.046, respectively). In contrast, the mRNA level of Numb was clearly enhanced after AS treatment (0.90±0.05 vs. 0.75±0.11, P = 0.019). In addition, consistent with the mRNA levels, the protein expressions of Notch-2, -3, -4 and JAG1 were reduced significantly (1.27±0.18 vs. 1.71±0.26, P = 0.004; 0.99±0.11 vs. 4.38±0.60, P = 0.001; 1.76±0.32 vs. 4.01±0.74, P = 0.002; 1.62±0.33 vs. 2.74±0.63, P = 0.002) and the Numb protein level was increased significantly (1.50±0.15 vs. 0.85±0.11, P = 0.001) in AS group compared with BDL group. Conclusion: AS may prevent cholestatic liver fibrosis via inhibition of the Notch signaling pathway, thereby inhibiting the abnormal proliferation of biliary epithelial cells. Results indicate that AS may be a potential treatment for cholestatic liver disease.

Abstract
Objective: To explore the clinical effect of a novel artery first and uncinate process first approach for laparoscopic pancreaticoduodenectomy(LPD), emphasizing the left lateral and posterior dissection of uncinate process (UP) via Treitz ligament approach. Methods: From April to November 2016, 18 patients received LPD with a novel approach in Pancreas Center of the First Affiliated Hospital with Nanjing Medical University. All patients were diagnosed as pancreatic head or peri-ampulla tumor, without major vessel invasion nor distant metastasis. For resection, routine caudal view was used in the first step, to dissect the anterior medial border between uncinate process and superior mesenteric vein(SMV). Lymphatic tissues were completely dissected form anterior surface of hepatoduodenal ligament. In the second step, left lateral view with camera from left para-umbilical trocar was used, Treitz ligament was incised, SMA root was exposed. After anticlockwise rotation and retraction of mesentery, the anatomic relationship between SMA trunk, inferior pancreaticoduodenal artery(IPDA), jejunal branch of SMV, and distal part of UP, could be perfectly exposed from left lateral view. SMA was dissected from its root until the position above the uncinate process and duodenum, IPDA was transected, distal part of UP was freed from SMA. In the third step, right lateral view and caudal view were alternatively used; proximal UP mesentery was completely dissected out from SMA root, CA root and posterior surface of hepatoduodenal ligament. Pancreaticoduodenectomy was completed in the forth step after transection of pancreatic neck and common hepatic duct. Results: The SMA root and distal UP were successfully dissected out via Treitz ligament approach in all 18 patients, among them, distal UP was completely excised in 8 patients from left view. Postoperative pathology showed R0 resection rate in 69%. Postoperative complication included intra-abdominal hemorrhage in 1 patient, pancreatic fistula in 7 patients(6 cases with grade A and 1 case with grade B), delayed gastric emptying in 4 patients (2 cases with grade A, 2 cases with grade B). Average postoperative hospital stay was (15.5±6.8)days. Conclusion: The novel artery first and uncinate process first approach through Treitz ligament could help surgeons to completely dissect the full length of meso-pancreas along celiac axis-SMA axis in LPD.

Abstract
Conditional logistic regression analysis and unconditional logistic regression analysis are commonly used in case control study, but Cox proportional hazard model is often used in survival data analysis. Most literature only refer to main effect model, however, generalized linear model differs from general linear model, and the interaction was composed of multiplicative interaction and additive interaction. The former is only statistical significant, but the latter has biological significance. In this paper, macros was written by using SAS 9.4 and the contrast ratio, attributable proportion due to interaction and synergy index were calculated while calculating the items of logistic and Cox regression interactions, and the confidence intervals of Wald, delta and profile likelihood were used to evaluate additive interaction for the reference in big data analysis in clinical epidemiology and in analysis of genetic multiplicative and additive interactions.

Abstract
Objective: To detect TOP2A protein expression and gene copy number alterations, and to analyze related clinical and pathological implications in pediatric neuroblastic tumors (NT). Methods: Immunohistochemistry was used to detect TOP2A protein expression. Fluorescence in situ hybridization (FISH) was used to detect numerical aberrations of TOP2A. Results: TOP2A protein was expressed in 59.1%(52/88) of cases, which was associated with differentiation (P=0.006), Ki-67 index (P<0.01) and MKI (P=0.001). Twenty-eight cases (35.0%, 28/88) showed TOP2A gene amplification, which was correlated with the age (P<0.01), clinical stage (P=0.028), high risk group (P=0.001), Ki-67 index (P=0.040) and differentiation (P=0.014). Survival analysis showed that TOP2A expression was related to survival rate. Multivariate analyses showed that TOP2A expression was an independent predictor for poor prognosis (P=0.010). Conclusions: More than half of the cases show TOP2A expression, which is more likely associated with NB, high Ki-67 index and high MKI. Cases with TOP2A expression have shorter survivals and poorer prognosis. TOP2A amplification is seen in 35% and likely occurs in patients older than 18 months and at advanced INSS stages (Ⅲ and Ⅳ). As a target of the anthracycline-based adjuvant drugs, TOP2A test can be used to select patient with NT for the therapy.

Abstract
Davidia involucrata, reputed to be a "living fossil" in the plant kingdom, is a relict tree endemic to China. Extant natural populations are diminishing due to anthropogenic disturbance. In order to understand its ability to survive in a range of climatic conditions and to design conservation strategies for this endangered species, we developed genic simple sequence repeats (SSRs) from mRNA transcripts. In total, 142,950 contigs were assembled. Of these, 30,411 genic SSR loci were discovered and 12,208 primer pairs were designed. Dinucleotides were the most common (77.31%) followed by trinucleotides (16.44%). Thirteen randomly selected primers were synthesized and validated using 24 individuals of D. involucrata. The markers displayed high polymorphism with the number of alleles per locus ranging from 3 to 12 and the observed and expected heterozygosities ranging from 0.083 to 1.0 and 0.102 to 0.69, respectively. This large expressed sequence tag dataset and the novel SSR markers will be key tools in comparative studies that may reveal the adaptive evolution, population structure, and resolve the genetic diversity in this endangered species.

Abstract
Objective:To analyze the clinical characteristics of patients with severe deep neck abscess,etiology,imaging,appropriate treatment selection in those patients,to improve the judgement and understanding of the disease.Method:Thirty cases of severe deep neck abscess treated from March 2010 to June 2015 were retrospectively reviewed,including the clinical characteristics,diagnosis and treatment strategy.Result:The sore throat,odynophagia,dysphagia,fever and difficulty breathing were the most common symptoms of severe deep neck abscess.The causes of deep neck abscess were tooth diseases(5 cases),foreign bodies in pharynx or esophagus(4 cases),the second branchial crack cyst with multiply abscess,uncertain cause(20 cases).Six of the above cases complicated with mediastinal abscess.Radiologic evaluation was performed on all of the patients to identify the most probable location of the abscess:parapharyngeal space,retropharyngeal space,masticator space,carotid space,etc.Twenty-five cases were treated by drainage via incising lateral neck and 4 patientsreceived abscess puncture aspiration.Life-threatening complications were developed in all cases,29 cases were cured but one case dead.Conclusion:The treatment of severe deep neck multispace abscesses should be mindful.Once deep neck abscesses are diagnosed,we should timely undertake surgical drainage via incising lateral neck.Emergency tracheostomy should be perform in some case like severe dyspnea,airway obstrucion.Antibiotics should be appropriately applied,and basic diseases and complications should be carefully controlled.
