Objective To compare the efficacy and safety of full-thickness peroral endoscopic myotomy (POEM) and circular myotomy for patients with severe achalasia.Methods The clinical data of 123 patients with severe achalasia who were admitted to the Second Xiangya Hospital of Central South University from August 2011 to May 2013 were retrospectively analyzed.Seventy patients who received full-thickness POEM were in the full-thickness myotomy group,and the other 53 patieuts who received circular myotomy were in the circular myotomy group.The clinical efficacies and incidences of complications of the 2 groups were compared.Patients in the 2 groups were followed up at the out-patient department till May 2014.The consecutive measurement data were presented by (x) ± s and analyzed using thc t test; the non-consecutive data were presented by M (range) and analyzed using the Wilcoxon rank test.Data before and after operation were compared using the repeated measure of analysis of variance.The count data were analyzed using the chi-square test.Results All the patients successfully received POEM.The operation time of the full-thickness myotomy group and the circular myotomy group were (57 ± 8)minutes and (63 ± 12)minutes,with significant difference between the 2 groups (t =3.421,P ＜0.05).The incidences of complications of the full-thickness myotomy group and the circular myotomy group were 14.3％ (10/70) and 11.3％ (6/53),with no significant difference between the 2 groups (x2=0.234,P ＞0.05).Atotal of 119 patients were followed up,with the median time of 18 months (range,12-24 months).The Eckardt scores at postoperative month 6 and 12 were 0 (range,0-3) and 0 (range,0-3) in the full-thickness myotomy group,and 0 (range,0-2) and 0 (range,0-3) in the circular myotomy group,with no significant difference between the 2 groups (Z =0.525,1.476,P ＞ 0.05).The sussess rates of the full-thickness myotomy group and the circular myotomy group were 98.6％ (69/70) and 98.1％ (52/53),with no significant difference between the 2 groups (x2=0.040,P ＞ 0.05).The diameters of the esophagus at postoperative month 6 of the full-thickness myotomy group and the circular myotomy group were (3.2 ± 0.3) cm and (3.4 ± 0.4) cm,with no significant difference between the 2 groups (t =1.927,P ＞ 0.05).The diameters of the esophagus at postoperative month 6 and 12 were significantly lesser than (5.9 ± 1.0) cm and (5.9 ± 1.0) cm before operation (F =780.923,493.018,P ＜ 0.05).No recurrence was detected in the 2 groups during the follow-up.Conclusion The short-term efficacy and incidence of complications of full-thickness myotomy and circular myotomy are comparable,while the operation time of patients who received full-thickness myotomy is shorter.

Purpose To analyze the relationships between glomerular filtration rate (GFR) measured by SPECT and renal parenchyma thickness and enhanced CT value measured by CT, and to explore predictive significance of CT in evaluating renal function of patients with hydronephrosis.Materials and Methods One hundred and fifteen patients diagnosed with unilateral hydronephrosis by ultrasound were retrospectively analyzed. GFR% (GFR percentage of affected kidney to the both kidneys) was measured by SPECT. CT% (percentage of affected renal parenchyma thickness to the both kidneys) and enhanced CT% (percentage of enhanced CT value of affected kidney to the both kidneys) were measured by pre- and post-contrast CT scan. According to GFR, the renal function was divided into mild-to-moderate impairment, severely impairment and non-function. Twenty-five volunteers were recruited as control group. CT%, enhanced CT% and GFR%among the four groups were compared, and the correlation of CT% and enhanced CT%with GFR% was analyzed to evaluated CT in predicting renal function.Results CT%, enhanced CT% and GFR% in mild-to-moderate impairment group was significantly greater than those in severely impairment group and non function group (F=20.24, 7.78 and 329.21,P<0.05). GFR% was positive correlated with CT% (r=0.58,P<0.05) and enhanced CT% (r=0.61,P<0.05). Area under curve (AUC) of CT% were 0.54, 0.79 and 0.83 for mild-to-moderate impairment, severely impairment and non-function, with sensitivity of 92.91%, 93.47%, 65.72%, and specificity of 35.33%, 59.47%, and 88.62%, respectively. AUC of enhanced CT% were 0.79, 0.89 and 0.96 for the three groups, with sensitivity of 97.51%, 80.02%, 97.66%, and specificity of 58.14%, 89.82% and 94.27%, respectively.Conclusion There was high correlation between renal function imaging by SPECT and CT in evaluating renal function of hydroneohrosis patients. Pre- and post-contrast CT scan can be used as complements in predicting renal function, and post-contrast CT with high accuracy.

Objective To investigate the relationship between serum uric acid (UA) level and abdominal obesity or metabolic syndrome (MS).Methods A total of 875 subjects,with 350 males and 525 females,aged 40-65 years old,were enrolled in this study.The clinical and biochemical data were collected and MRI was used to assess the visceral and subcutaneous adipose tissues.The relationships between UA level and abdominal obesity or MS were analyzed,and the cut-off values of UA for abdominal obesity and MS were determined.Results Raised risks of abdominal obesity (OR =4.35,95％ CI 1.91-9.90 in males; OR =5.44,95％ CI 2.41-12.31 in females) and MS (OR =4.47,95 ％ CI 2.08-9.62 in males; OR =11.62,95％ CI 3.43-39.37 in females) were observed with the increase of UA level.The multiple logistic regression analysis showed that UA was an independent risk factor for hypertriglyceridemia (OR =2.23,95％ CI 1.02-4.87 in males ; OR =3.04,95％ CI 1.49-6.23 in females) in all subjects and for abdominal obesity(OR =3.23,95％ CI 1.32-7.91) and hypertension (OR =2.35,95％ CI 1.37-4.05)in the females.Among the females,the regression line analyzed by simple correlation indicated that the UA level of 244.0 μmol/L was corresponded to the visceral adipose tissue area of 80 cm2.The optimal cut-off point of UA for the diagnosis of MS was 258.8 μmol/L determined by the receiver operating characteristic curve.Conclusions The level of UA is closely correlated with abdominal obesity and MS in the middleaged Chinese.The elevated UA level is an independent risk factor for abdominal obesity and MS in the female.
