Objective To investigate the difference of complication incidence, death rate, quantity of lymphadeneetomy, lymphatic metastasis rate and long-term survival rate in thoracic squamons cell carcinoma of esophagus between three fields lymphadenectomy (3-FL) and traditional method. Methods Homoehronous 96 esophageal cancer patients were fractionated in two groups, 46 patients for 3-FL, the other 50 patients for traditional method. Results The average quantity of lymphadenectomy was 39.28 pieces per patient in 3-FL, and was significantly higher than 13.30 pieces per patient in traditional method (P <0.01). The rate of metastatic lymphatic nodes was 73.91%(34/46) in 3-FL patients, significantly higher than38.00%(19/50) in traditional method patients. For incidence of postoperative complications, recurrent laryngeal nerve damage and respiratory complication in 3-FL patients was significantly higher than patients in traditional method (P <0.05). The chest fluid obviously inereasod in 3-FL patients than in traditional method patients. There was significant contrast in 3-year survival rate between 3-FL patients and traditional method patients. Conclusion The there fields lymphadenectomy expand scope of lymphdenectomy effectually, accurate the staging of thoracic esophageal carcinoma. At the same time, a lot of evidence was found in raising survival rate for 3-FL. Disadvantage of 3-FL was severe surgical trauma, high incidence of complication, and a long recovery time after operation.

Objective To study the influence of traction on the blood circulation of femur head and its evaluation by DSA. Methods Using micro-catheter, transfemoral selective femoral circumflex arteriography in 22 healthy dogs was performed in unilateral hip before (Group A,n =22) and immediately (Group B,n=22) ,30( Group D,n =22) ,60(Group E,n=20) ,90( Group F,n = 10),120 (Group G,n=10) minutes during 2 kg skin hip traction, and immediately after traction removal (Group H,I,J,L and 0), and 30 minutes after traction removal with 60,90 and 120 minutes continuous traction(Group K,M and P),and 60 minutes after traction removal with 90 and 120 minutes continuous traction(Group N and Q). DSA was also performed immediately during 4 kg weight traction before continuous traction in 12 hips( Group C).Blood circulation of the femoral head was evaluated mainly by observing its perfusion and time of circulation. Femur head perfusion was assessed as good scoring 3,poor scoring 2 and extremely poor scoring 1. Femur head circulation time was assessed as normal scoring 3 .prolonged scoring 2 and remarkably prolonged scoring 1. Analysis of variance was employed for analysis of the angiographic findings between different groups.Results Good femoral head perfusion in Group A to Q was 22,0,0,0,0,0,0,22,22,1,18,0,0,8,0,0 and 1 hips respectively, poor one was 0,22,8,22,15,4,1,0,0,15,2,4,6,2,1,3 and 8 hips, respectively,extremely poor one was 0,0,4,0,5,6,9,0,0,4,0,6,4,0,9,7 and 1 hips, respectively; and normal femoral head blood circulation time was 22,0,0,0,0,0,0,22,22,1,18,0,0,8,0,0 and 1 hips, respectively, prolonged one was 0,22,9,22,15,4,2,0,0, 15,2,5,7,2,2,4 and 8 hips, respectively, remarkably prolonged one was 0,0,3,0,5,6,8,0,0,4,0,5,3,0,8,6 and 1 hips, respectively. F value of femoral head perfusion among group A and B,group B and C,group B,D,E,F and G,Group H,I,J,L and O,group K,M and P,Group N and Q was 437. 48,30. 25,29. 04,132. 69,143. 73,25.20, respectively, and their P value was all <0. 01. F value of femoral head circulation time among group A and B,group B and C,group B,D,E,F and G,Group H,I,J,L and O,group K,M and P,Group N and Q was 386. 26,31. 83,22.43,141. 94,119.69,21.68, respectively, and their P value was all < 0.01. Conclusions Traction could lead to ischemic response and circulation disorder of canine femoral head. The longer the traction time or the bigger the traction weight was, the poorer the femoral head perfusion and the longer the femoral head circulation time were, and the slower they recovered. DSA could directly reflect these changes in the femoral head with these angioarchitectural and hemodynamic indexes.

Recent studies have found that visfatin is involved in lipid metabolism in patients with nonalcoholic fatty liver disease (NAFLD), and about 25% of NAFLD patients have thyroid dysfunction. It has also been found that visfatin is involved in autoimmune regulation through the autocrine or paracrine pathways, which is associated with the involvement of the thyroid gland in autoimmune regulation of the body. This article preliminarily explores the association of visfatin with thyroid dysfunction in NAFLD patients and points out that the measurement of visfatin may help with the early identification of thyroid dysfunction in NAFLD patients.

Objective To evaluate the toxicities and long-term survival of a pilot study of radical surgery followed by concurrent capecitabine and radiotherapy for stage Ⅱ/Ⅲ rectal cancer patients.Methods From March 1,2005 to December 31,2007,131 pathologically proved stage Ⅱ and Ⅲ rectal cancer patients received radical surgery followed by chemoradiotherapy and adjuvant chemotherapy.Capecitabine was delivered daily in twice,for 2 weeks followed by a 2nd cycle after a rest of 7 days during radiotherapy,with the dosage of 1600 mg/m2/d.Three-dimensional conformal radiotherapy was encouraged to the dose of 50 Gy in 25 fractions,and Oxaliplatin/5-fluorouracil or leucovorin based adjuvant chemotherapy was recommended.Results Grade 3 +4 toxicities during concurrent chemoradiotherapy were observed in 28.2％ of patients.The follow-up rate was 93.9％.The 3-year overall survival (OS),locoregional-free survival and distant metastasis-free survival rates were 85.1％,96.7％ and 79.5％,respectively.Among the 31 patients with relapse,5 had loco-regional recurrence and 28 had distant metastasis.Univariate analysis indicated that patients with low and moderate-low differentiated adenocarcinoma,no adjuvant chemotherapy,stage ⅢC disease or positive lymph node ratio (LNR) more than 30％ had lower OS ( x2 =15.49,15.85,8.80 and 9.76,P ＝ 0.000,0.000,0.011 and 0.002 ).Patients with N2 disease had more loco-regional recurrence.Patients with stage ⅢC,without adjuvant chemotherapy,or LNR more than 30％ were at higher risk of distant metastasis ( x2 =6.51,11.57 and 9.70,P =0.034,0.001 and 0.002 ).However,patients who didn ' t receive adjuvant chemotherapy were likely to have low differentiated adenocarcinoma and T4 stage disease ( x2 =7.20,6.48,P =0.027,0.039).Conclusions After radical surgery and concurrent eapecitabine and radiotherapy for stage Ⅱ/Ⅲ rectal cancer patients,loco-regional recurrence rate is pretty low.Distant metastasis is the main treatment failure.

Objective To analyze the pregnancy outcomes of fetal tetralogy of Fallot and to explore its prenatal diagnosis and treatment procedures. Methods The clinical data of 63 cases of fetal tetralogy of Fallot (62 cases were singleton and 1 case was one of twin) were collected retrospectively from November, 2013 to November, 2017 in Beijing Obstetrics and Gynecology Hospital. Results (1) Totally, 63 cases out of 46 352 pregnancies were diagnosed fetal tetralogy of Fallot by fetal ultrasonic cardiogram with about 0.136%(63/46 352) occurrence rate, and the mean gestational age was (23±3) weeks. And 50 cases (79%, 50/63) terminated pregnancy by induced labour. (2) Totally, 57 cases (90%,57/63) accepted genetic diagnosis.Eight cases (13%, 8/63) existed chromosome abnormality including 21-trimosy in 6 cases, 18-trisomy in 1 case and 22q11.2 microdeletion syndrome in 1 case; and these 8 cases were determined before 28 gestational weeks. (3) And 13 cases (21%, 13/63) of no fetal genetic abnormality selected to continue pregnancy. Twelve cases underwent full term delivery (5 cases were cesarean section delivery and 7 cases were vaginal delivery). Twelve newborns underwent surgical radical operation on heart malformation and got recovery. One case underwent preterm cesarean section at 35 gestational weeks for one of twin, and the newborn with tetralogy of Fallot was dead. The other the newborns survived and were followed up for tetralogy of Fallot surgery from 1 month to 3 years old after birth and recovered.Conclusions Fetal tetralogy of Fallot mainly is diagnosed by ultrasonic cardiogram in the second trimester. The gestational age of diagnosis may be as early as 15 gestational weeks. Fetal tetralogy of Fallot with no genetic abnormality could underwent radical heart malformation operation after birth. It is necessary to undergo genetic testing on fetal tetralogy of Fallot and prenatal multidisciplinary counseling as well.

Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.
