Adenoid hypertrophy is a disease that mostly occurs among children of 3-5 years old. It is caused by repeated inflammation and infection of nasopharynx and its adjoin parts, or the adenoid itself, which will finally leads to pathological hyperplasia of adenoid. With so much information we have acquired about this disease, its specific mechanism remains unknown. In recent years, some researches have indicated that adenoid hypertrophy may have something to do with extra-gastroesophageal reflux, in which pepsin plays a very important role, and pepsin will do a series of pathological damages to the upper airway as it reaches the upper respiratory tract. Based on relative domestic and foreign literature, this paper attempts to make a review about the relationship between gastroesophageal reflux and adenoid hypertrophy.

Objective To analyse the long-term result and prognosis of 18 FDG PET/CT positioning three - dimensional conformal radiotherapy ( 3 DCRT ) for stage Ⅲ non - small cell lung cancer. Methods Sixty-four cases with stage Ⅲ non-small cell lung cancer (clinical stage Ⅲa- Ⅲb ) were randomly divided into two groups: PET/CT positioning three-dimensional conformal radiotherapy group (PET/CT group) and the conventional CT positioning three-dimensional conformal radiotherapy group (conventional CT group). In the PET/CT group, the target volume and critical organs were sketched according to PET/CT after fusion of the PET and the CT images; the treatment plan was worked out, then conventional fractionated 3DCRT ( total dosage around 40 Gy) followed by field-shrinked radiotherapy to a total dose of 65 Gy or sowas performed ;in the conventional CT group, the target volume and critical organs were sketched according to CT and 3DCRT were performed to the same total dose; All cases were treated with the TP scheme (paclitaxel 175 mg/m2,d1 ,cisplatin 40 mg,d2-4) adjuvant chemotherapy for 6 cycles after the radiotherapy. Results The followup rate was 100%. The number of patients who completed the 1-,2-and 5-year follow-up were 40,20 and 11 respectively ;The number of patients of the PET/CT group and conventional CT group were 23 and 17,11 and 9,7 and 4 respectively. Target volumes of 13 cases in the PET/CT group were changed. The complete remission and partial remission rates of the two groups were 13% 、66% and 19% 、53% (x2 = 0. 33, P =0. 564), respectively. The 1-,2-and 3-year local control rates of the PET/CT group and conventional CT group were84 % 、66% 、53 % an d72% 、59% 、44% ( x2 = 2.36, P = 0. 124 ) respectively. The1 -, 2-and 3-year survival rates were 72% 、34% 、22% and 53% 、28% 、13% (x2 =2. 46,P =0. 117) respectively. The level-1 and level-2 lungs' and trachea's late radiation injury of the PET/CT group and the conventional CT group were 28% and 53% ( x2 = 4. 14, P = 0. 042 ), respectively. The hilar and mediastinal lymph node recurrence rates of the PET/CT group were lower than those of the conventional CT group, were 3% ,25%(P = 0. 026) and 6%, 28% ( P = 0. 042 ), respectively. The main reason for treatment failure was distant metastasis both in the PET/CT group and conventional CT group,56% and 47% (x2 = 0. 56,P = 0. 453 ),respectively. Conclusions PET/CT, as a method of sketching the target of stage Ⅲ non-small cell lung cancer, can improve the radiation treatment plan, reduce the recurrence rate of hilar and mediastinal lymph nodes, meanwhile it can not improve the long-term survival rate; Distant metastasis was the main reason of failure.

Objective To investigate the effect of sevoflurane preconditioning-postconditioning on thromboxane A2 and prostaglandin I2 during myocardial ischemia-reperfusion (I/R) in rats. Methods Fifty healthy male Wistar rats weighing 250-280 g were randomly divided into 5 groups (n = 10 each) : sham operation group (group S) , I/R group, sevoflurane preconditioning group (group Spr), sevoflurane postconditioning group (group Spo)and combination of sevoflurane preconditioning and postconditioning group (group Spr + po). Myocardial I/R was produced by occlusion of anterior descending branch of left coronary artery for 30 min followed by 2 h reperfusion in anesthetized rats. In group S the anterior descending branch was only exposed but not ligated. Group Spr received 15 min inhalation of 2.5 % sevoflurane and 15 min wash-out 30 min before ischemia. Group Spo received 5 min inhalation of 2.5% sevoflurane 1 min before reperfusion. Arterial blood samples were taken at 2 h of reperfusion for determination of the levels of MB isoenzyme of creatine kinase (CK-MB) , lactate dehydrogenase (LDH) , cardiac troponin I (cTnI), thromboxane B2(TXB2), and 6-keto-prostaglandin (6-keto-PGF1α) and platelet maximum aggregation rate. TXB2/6-keto-PGF1α ratio was calculated. The myocardial tissues were taken for microscopic examination. Mitochondria] injury was assessed by using Flameng score and stereology (Specific surface, δ and Numerical density on area, NA) .Results Compared with group S, the levels of CK-MB, LDH, cTnI, TXE2 and 6-ketoPGF1α, TXB2/6-keto-PGF1α ratio, platelet maximum aggregation rate and Flameng score were significantly increased, while δ and NA were significantly decreased in group I/R (P < 0.05 or 0.01) . The levels of CK-MB,LDH and cTnI, TXB2/6-keto-PGF1α ratio and Flameng score were significantly lower, and 6-keto-PGF1α level, δand NA were significantly higher in Spr and Spo groups than in group I/R ( P < 0.05 or 0.01) . The levels of CKMB, LDH, cTnI and TXB2 , TXB2/6-keto-PGF1α ratio, platelet maximum aggregation rate and Flameng score were significantly lower and 6-keto-PGF1α level,δ and NA were significantly higher in group Spr + po than in Spr and Spo groups(P < 0.05). Conclusion Sevoflurane preconditioning-postconditioning can reduce myocardial I/R injury through inhibiting the release of thromboxane A2 and promoting the release of prostaglandin I2 in rats.

Objective To investigate the changes of perioperative right ventricular function after pulmonary resction. Methods 45 cases of pulmonary resection were divided into four groups.Group Ⅰwas wedge resection(n = 10), GroupⅡ was lobectomy(n = 19), Group Ⅲ was double lobectomy(n=7)and Group Ⅳ was pneumonectomy(n=9). The changes of CVP, PAMP, PEP/ET, Sa, VTIs, RVSP, Ea/Aa, and Tel were evaluated by traditional ultrasonic and tissue Doppler ultrasonic techniques at different time inter- vals (pre-operation, 5-7 days orland 1 month post-operation), Results Compared with the pre-operation CVP, the indexes of all groups have no significant changes post-operatively. Wedge resection didn' t obviously influence right cardiac after load and systolic function/diastolic function. No evidet changes detected in Tei pre-and post-operatively. However, the indexes (PAMP, RVSP and PEP/ET ratio) reflecting right cardiac afterload evidently increased at post-pneumonectomy or lobectomy group5- 7 days post-opera- tive. All these reflect the decrease of Tei, which was more obvious in pneumonectomy than in lobectomy group. Right cardiac after- load, systolic/diastolic function and Tel index recovered to pre-operative level 1 month post-operation in single lobectomy group. But the above indicators, especially the Tel, were still high in double lobectomy and pmeunonectomy groups 1 morth post-operation.Tei index is positively correlated with PAMP and is weakly correlated with PET/ET ratio and Ea/Aa ratio. Conclusion Pulmonary wedge resection doesn't evidently influence right cardiac function. However, right cardiac diastolic function evidently decreases temporarily at lobectomy group. The systolic function and diastolic funetions decrease after double-lobectomy and pneumonectomy and it's more evident in pneumonectomy group. Though the right cardiac afterloads of lobectomy, double lobectomy and pneumonectomy groupa all increase significantly post-operativlye, only the former recover to pre-operative level 1 month after surgery.

Objective To summarize the features of computed tomography (CT) and magnetic resonance imaging (MRI) of autoimmune pancreatitis (AIP) and investigate the key points of diagnosis and identification.Methods The retrospective and descriptive study was conducted.The clinical data of 21 patients with AIP who were admitted to the Affiliated Hospital of Inner Mongolia Medical University between February 2012 and February 2015 were collected.All the patients underwent plain and enhanced scans of CT and MRI,and magnetic resonanced cholangio-pancreatography (MRCP),and then received hormone therapy.Eleven patients with pancreatic cancer and 11 normal subjects who were diagnosed by MRI in the same period were selected,and apparent diffusion coefficient (ADC) was calculated and compared.Observation indicators:(1) situation of imaging examination:① pancreatic manifestations:density,signal,atrophy,calcification and enlargement of pancreas,change of pancreatic duct,② manifestations out of pancreas:changes of biliary tract system and kidney,③ diffusion weighted imaging (DWI) and ADC:comparisons of ADC among AIP,pancreatic cancer and normal pancreas;(2) diagnosis;(3) treatment and follow-up.The follow-up using outpatient examination and telephone interview was performed to detect the clinical symptoms and signs up to February 2016.Measurement data with normal distribution were represented as (-x)-± s.Comparisons among groups were done using one-way ANOVA.Pairwise comparison was analyzed by Dunnett'T3 test.Results (1) Situation of imaging examination:Of 21 patients,17 received scan of CT and 11 received scan of MRI (7 combined with scan of CT).① Pancreatic manifestations:14 patients had diffuse enlargement of pancreas,with full edge and “sausage-like” change.Plain scan of CT showed uniform isodense shadow,and enhanced scan showed that reduced enhancement in arterial phase and gradually homogenous enhancement in portal vein phase and lag phase with no enhancement in edge of pancreas.Plain scan of MRI showed lesions were manifested as slight hypointensity on T1 weighted imaging (T1WI),slight hyperintensity on T2WI and hyperintensity on DWI.Enhanced scan of MRI showed delayed enhancement,edge of lesions was manifested as slight hypointensity on T1WI and T2WI,without enhancement.Atrophy and calcification of pancreas:3 patients had atrophy of pancreatic parenchyma in which scattered calcification were seen.Enlargement of pancreas:4 patients had localized enlargement of pancreas showing “false tumor-like” change,including 2 with localized enlargement in head of pancreas.Change of pancreatic duct:MRCP showed that diffuse stenosis,local stenosis and local dilatation of pancreatic ducts were respectively detected in 4,3 and 1 patients.② Manifestations out of pancreas:11 patients had changes of biliary tract system,showing intrahepatic bile duct and common bile duct dilation,partial stenosis and extensive bile duct wall thickening.Enhanced scan of MRI showed there was obvious enhancement of bile duct wall.MRCP of 4 patients showed that the beak-like stenosis was seen in the distal common bile duct.Three patients had kidney changes,enhanced scan of CT showed that kidney demonstrated patch-shape hypodense shadow in arterial phase and homogenous enhancement of patch-shape hypodense shadow in lag phase,and plain scan of MRI showed that kidney lesions demonstrated equal signal on T1WI fat suppression (FS) and patch-shape low signal on T2WI FS.Lesions had gradually homogenous enhancement in substance phase and lag phase.③ DWI and ADC:lesions in patients with AIP and pancreatic cancer demonstrated high signal on DWI (b =1 000 s/mm2) compared with adjacent tissues (no involvement in pancreas or normal pancreatic parenchyma),ADC of pancreas in patients with AIP,with pancreatic cancer and with normal population was (0.001 30 ± 0.000 35)mm2/s,(0.000 80 ± 0.000 14) mm2/s and (0.001 60-± 0.000 24) mm2/s,respectively,with a statistically significant difference (F =30.409,P < 0.05).There were statistically significant differences between patients with pancreatic cancer and patients with AIP or normal population (P < 0.05) and no statistically significant difference between patients with AIP and with normal population (P > 0.05).(2) Diagnosis:11 patients were diagnosed by CT examination,with a diagnostic accuracy of 11/17.Eight patients were diagnosed by MRI examination,with a diagnostic accuracy of 8/11.One patient was misdiagnosed as cancer of pancreatic head by CT and MRI examinations,and 1 was misdiagnosed as cancer in the distal common bile duct.(3) Treatment and follow-up:21 patients underwent regular hormone therapy,and 40 mg prednisolone was given orally a daily for 3-4 weeks and then gradually reduced to 5 mg up to complete relief of the symptoms.All the 21 patients were followed up for 12-45 months.Of 17 patients with abdominal pain and distension,symptoms of 7 patients disappeared and symptoms of 10 patients decreased or occasionally occurred.Of 10 patients associated with jaundice,symptoms of 7 and 2 patients disappeared and decreased,respectively,and symptoms of 1 patient subsided.Conclusion CT and MRI examinations of pancreas demonstrate “sausage-like” and “false tumor-like” changes,the non-neoplastic bile and pancreatic duct stenosis combined with IgG4 related diseases in other organs is an important imaging evidence for diagnosis and differential diagnosis of AIP.

Objective To investigate the relationship between body fat distribution and pulse wave velocity (PWV) in middle-aged and aged population. Methods Two hundred patients received health examination were enrolled into the male group (103 cases) and the female group (97 cases). Visceral fat volume (VFV), subcutaneous fat volume (SFV) and ba-PWV were determined. Results Compared to patients in the female group, patients in the male group had significantly higher VFV values [(3.17 ± 0.84) kg vs (2.30 ± 0.94) kg], and lower SFV values [(15.56 ± 3.49) kg vs (17.69 ± 4.82) kg], In the male group, there existed a positive correlation between ba-PWV and age, VFV, fasting blood glucose,SBP and DBP. In the female group, a positive correlation was found between ba-PWV and age, SFV, TG, BUN, SBP and DBP, while a negative correlation was observed for HDL-C and Apo A1. Conclusion There was gender differences in body fat distribution in middle-aged and aged healthy population. In the male group , age, VFV, SBP, and DBP were the only independent and significant risk factors for ba-PWV. In the female group , age, SBP and Apo A1 were the independent risk factors for ba-PWV.

In recent years,liver transplantation donor shortage as one of world medical problems is paid more attention by domestic and overseas scholars.In view of that,heterotopic auxiliary liver transplantation emerges which transplants the whole or some parts of a donor liver outside the original liver position on the condition that some parts or the whole of the original liver were retained.As for the liver transplantation with poor conditions on portal vein,reconstruction of portal vein has become an aporia.Based on this,some scholars put forward the theory——arterialization of portal vein(PVA),namely a method to increase arterial blood supply or replace portal vein blood perfusion of liver by establishing some pathes among artery and portal vein or its branches.The research background and current situation of heterotopic auxiliary liver transplantation with portal vein arterialization,the transplanting position of donor liver,vessel reconstruction,dynamics mechanism after reconstruction and liver regene-ration are summarized in this review.
