Objective To describe the diagnostic approach and clinical outcomes of fetal intraabdominal extralobar pulmonary sequestration (IEPS).Methods Three cases of IEPS were diagnosed prenatally by ultrasound in our center.The data of these 3 cases and 43 cases in prior studies from 1986 to 2016 were retrospectively reviewed.The prenatal sonographic features,treatment,and outcomes were collected.Results The gestational age of diagnosis IEPS was (24.5±5.9)weeks,the male-to-female ratio was 3-4∶1,78.3% (36/46) of IEPS masses located on the left side,47.8% (22/46) of lesions were homogenous and hyperechoic,8.7% (4/46) of cases associated anomalies,78.3% (36/46) of patients were preformed resection and postoperative recovery and subsequent course were uncomplicated.Feeding arteries were detected in 15.2% (7/46) cases and confirmed by surgery or autopsy.Conclusions Prenatal ultrasound has the diagnostic accuracy of IEPS.Feeding arteries noted on color Doppler are strongly indicators of IEPS.Postsurgical outcomes are favorable.

OBJECTIVETo evaluate clinical results of plate on the metatarsal side to reconstruction of tarsometatarsal joint dislocations secondary to diabetic charcot foot.

METHODSSeven patients (9 feet) patients with tarsometatarsal joint dislocations secondary to diabetic charcot foot were treated with plating from April 2012 to December 2014. All patients were male, and 5 cases were on the unilateral side and 2 cases were on the bilateral sides. The age of patients ranged from 45 to 52 with an average of 48 years old. The history of diabetics was from 6 to 15 years. X-ray and CT were used to evaluate fractures healing,and AOFAS was applied to estimate recovery of joint function.

RESULTSAll patients were followed up from 12 to 24 months with an average of 19 months. All incisions were healed at stage I . No infection, loosening and breakage of internal fixation, bone nonunion were found after operation. According to postoperative X-ray and CT results, the time of fracture healing ranged from 10 to 20 weeks with an average of 16 weeks. Six feet got excellent results, 2 good and 1 moderate based on AOFAS scoring.

CONCLUSIONTarsometatarsal joint dislocations secondary to diabetic charcot foot treated with plate on the metatarsal side could obtain stable fixation and got satisfied early clinical results.

Objective:To assess effect of age on the characteristic of letf ventricular (LV) twist-displacement loop in health volunteers by velocity vector imaging (VVI) and to provide a new method for LV function evaluation in clinic.
Methods:Atfer obtaining basal and apical LV short-axis images in 98 healthy volunteers (18-75 years old) by 2-dimensional echocardiography, we use VVI sotfware to analysis LV twist motion and radial displacement at each plane off-line. hTe peak LV twist (Ptw), the peak untwist velocity (PutwV), the proportion of untwist in isovolumetric relaxation period (Iutw%) and LV radial displacement (Dis) were measured and calculated. Then we constructed LV twist-displacement loop and compared the characteristic of them among different groups.
Results:Ptw increased gradually with the increase in age. The biggest PutwV was in the group of 30-60 years old. Iutw%increased gradually before 60 years old, then decreased atfer that. Dis was not obviously different among the three groups. hTe characteristic of LV twist-displacement loop was like the configuration of 8. There was a linear relation between twist and displacement during systole, and the slope increased gradually with the increase in age. During early diastole, the relatively small radial expanding displacement displayed with untwisting, resulting in a much steeper twist-displacement relationship curve occurred in each group, which was getting smooth gradually when the radial expanding displacement increased during mid to late diastole.
Conclusions:VVI can be used to effectively and noninvasively assess LV twist-displacement loop with change in age and provide important information for LV function. hTe effect of age must take into account when evaluate the LV function by the twist-displacement loop.

Objective To evaluate the efficacy and safety of composite milk clotting enzyme capsules in children with functional dyspepsia.Methods A multicenter,randomized,open-label clinical trial was carried out in 4Guangzhou hospitals during Feb.2012 to Mar.2013.Children with functional dyspepsia on basis of Rome Ⅲ criteria were enrolled and treated with composite milk clotting enzyme capsules.Total symptom score and drug-related adverse reactions were evaluated after one-week and two-week therapy.The treatment outcome were divided into very effective,fairly effective and ineffective according to the symptom score changes.Superiority test was done for effectiveness of the treatment based on efficacy difference by 10％ regarded as superiority.Results Two hundred and one children were enrolled.One hundred and ninety-six children completed the study as planned.After two-week therapy,better effective rate and total effective rate were 68.88％ and 87.76％,higher than those of one-week therapy (27.04％,76.02％) (U =2.935,P ＜ 0.05).The lower limits of 95 ％ confidence interval of difference in symptoms improve rate,better efficacy rate and symptom score decrease rate between two-week and one-week therapy were more than 10％,and two-week therapy was superior to one-week therapy.No significant drug-related adverse reaction was found during the study.Conclusions Composite milk clotting enzyme capsules can improve functional dyspepsia symptoms significantly.The effectiveness of two-week of treatment is better than that of one-week treatment.No obvious drug-related adverse reaction is observed.

Objective To analyze computed tomography imaging features of primary adrenal schwannoma.Methods The clinical and radiological data of six cases of adrenal schwannoma confirmed by histopathology were analyzed in this study.Results All six cases of adrenal schwannoma were well-circumscribed,round-like or oval-like,solid and cystic tumors,in which two cases were with calcification,and three cases with septations.On the enhanced CT images,all six tumors displayed progressive enhancement.Conclusion Adrenal schwannoma usually presents a well-defined heterogeneous mass with cystic degeneration,sepations,calcification and characteristic progressive contrast enhancement.

OBJECTIVE:To determine serum concentrations of western medicines in patients treated with "traditional Chinese antiepileptic medicine" alone and to evaluate the curative effects.METHODS:A total of 60 epileptic patients who visited our hospital between Feb.1997 and June 2006 were subjected to plasma drug level monitoring and during which the patients were treated with "traditional Chinese antiepileptic drugs" alone.Plasma concentrations of 4 kinds of western medicin-es were determined by FPIA.RESULTS:Of the 60 cases,valproic acid,carbamazepine,phenytoin and phenobarbitone were detected in 18,40,41,and 47 cases/times,respectively.On average,more than two kinds of western medicines were detected in every patient,and the blood concentrations were mostly beyond effective plasma drug concentration.The total curative effects were unsatisfactory.CONCLUSION:The fact that western medicine ingredients detected in these traditional Chinese antiepileptic medicines is inconformity with medication principle of epilepsy.Traditional Chinese antiepileptic medicines should be used with caution in the clinic in the treatment of epileptic patients.
