Objective To explore the factors which are related to the reoperation and relapse hiatus hernia in children.Methods Between Jan.2002 and May 2013,64 patients who suffered from hiatus hernia in Children's Hospital of Fudan University were divided into uneventful group (U group,n =49) and reoperation group (R group,n =15).The ages at operation,barium swallow examinations,operative procedures,findings during the operation and the followup of these two groups were reviewed.Results The average ages at operation in U group and R group were (14.70 ± 0.79) months and (13.60 ± 0.59) months,respectively.The major symptoms before the second operation in R group was vomiting(6 cases),pneumonia (4 cases) and dysphagia (2 cases).Asymptomatic recurrence was found in 3 patients.Through barium swallow examination,short esophagus was found in 10 cases in U group,while 3 cases were reported in R group.However,during the operation,the length of intra-abdominal esophagus without tension could be obtained with average (3.33 ± 0.86) cm in these short esophagus patients,which was only (3.18 ± 1.14) cm in those normal esophagus patients.There was no significant difference between the U group and R group in the width of the hiatus and the ratio of stomach above the hiatus.The length of esophagus which mobilized during operation was shorter in R group than that in U group(P =0.003).The difference of operative methods and the ratio of large hernia between these two groups could not be found.The common cause of failure in R group was herniated fundoplication (9 cases),which was followed by disputed fundoplication (4 cases),twisted fundoplication (1 case) and rupture of esophagus (1 case).The average follow up time was (8.3 ± 4.2) months in R group.Vomiting was found in 3 patients,and pneumonia was found in one case in R group after the second operation.The symptoms of these four patients were relieved half year later postoperatively.Conclusions The age,symptoms,size of the hiatus,short esophagus,and the operative methods are not related to the reoperation in hiatus hernia.But if the length of intra-abdominal esophagus without tension was not obtained enough,it may contribute to the recurrence of hiatus hernia.Wrap herniation has now become the most common mechanism of failure requiring reoperation.

Some unhealthy life habits, such as long-term smoking, heavy drinking, sexual overstrain and frequent stay-up could induce the Yin deficiency symptoms of zygomatic red and dysphoria. Stems of Dendrobii officinalis flos (DOF) showed the efficacy of nourishing Yin. In this study, the hyperthyroidism Yin deficiency model was set up to study the yin nourishing effect and action mechanism of DOF, in order to provide the pharmacological basis for developing DOF resources and decreasing resource wastes. ICR mice were divided into five groups: the normal control group, the model control group, the positive control group and DOF extract groups (6.4 g · kg(-1)). Except for the normal group, the other groups were administrated with thyroxine for 30 d to set up the hyperthyroidism yin deficiency model. At the same time, the other groups were administrated with the corresponding drugs for 30 d. After administration for 4 weeks, the signs (facial temperature, pain domain, heart rate and autonomic activity) in mice were measured, and the facial and ear micro-circulation blood flow were detected by laser Doppler technology. After the last administration, all mice were fasted for 12 hours, blood were collected from their orbits, and serum were separated to detect AST, ALT, TG and TP by the automatic biochemistry analyzer and test T3, T4 and TSH levels by ELISA. (1) Compared with the normal control group, the model control group showed significant increases in facial and ear micro-circulation blood flow, facial temperature and heart rate (P < 0.05, P < 0.01), serum AST, ALT (P < 0.01), T3 level (P < 0.05), TSH level (P < 0.05) and notable deceases in pain domain (P < 0.01), TG level (P < 0.01). (2) Compared with the model control group, extracts from DOF (6 g · kg(-1)) could notably reduce facial and ear micro-circulation blood flow, facial temperature and heart rate (P < 0.05, P < 0.01) and AST (P < 0.05) and enhance pain domain (P < 0.01) and TG (P < 0.01). Extracts from DOF (4 g · kg(-1)) could remarkably reduce AST and ALT levels (P < 0.01, 0.05). Extracts from DOF (6 g · kg(-1) 4 g · kg(-1)) could significantly reduce T3 and increase serum TSH level (P < 0.05). DOF could improve Yin deficiency symptoms of zygomatic red and dysphoria in mice as well as liver function injury caused by overactive thyroid axis. According to its action mechanism, DOF may show yin nourishing and hepatic protective effects by impacting thyroxin substance metabolism, improving micro-circulation and reducing heart rate.

Endoscopic ultrasonography (EUS)is routinely performed before endoscopic submucosal dissection (ESD)for treatment of upper gastrointestinal stromal tumors.However,when a miniprobe sonography (12,15 and 20 MHz)was used,the size of tumor revealed by EUS was often inconsistent with what it actually was,which might increase the difficulty of ESD and the risk of perforation and massive bleeding.Aims:To investigate the value of standard probe (5 and 7.5 MHz)EUS in detecting the size of upper gastrointestinal stromal tumors before ESD.Methods:Clinical data of patients who were suspicious of esophageal and gastric stromal tumors by gastroscopy and EUS from Jan.2012 to Oct.2014 at the Renmin Hospital of Wuhan University were collected.Of them,195 cases treated by ESD were retrospectively analyzed.Results:Of 195 cases treated by ESD,37 cases diagnosed by standard probe EUS and 108 cases diagnosed by miniprobe EUS were confirmed as stromal tumors by pathology.Fourteen cases were failure for ESD and then transferred to surgical treatment,one was due to misjudgement of the origin of tumor by standard probe EUS and 9 were due to misjudgement of the size of tumor by miniprobe EUS.The misjudgement rate of standard probe EUS was lower than that of miniprobe EUS with an insignificant difference (2.7%vs.8.3%,P>0.05).In 9 cases misjudged by miniprobe EUS, the size of tumor presented by miniprobe EUS was significantly smaller than its real size [(1.22 ±0.51)cm vs.(3.97 ±1.06)cm,P<0.01].ESD was avoided or terminated in 3 cases because of the accurate estimation of tumor origin, structure and blood flow by standard probe EUS.Conclusions:For patients who are going to receive ESD for suspected upper gastrointestinal stromal tumors,it would be best to select standard probe EUS to detect the size,origin and blood flow of the tumor before ESD.It will decrease the risk and improve the success rate of ESD.
