Objective To evaluate the clinical value of CHO-hTSHR cells in detecting thyroid stimulating antibody (TSAb). Methods The cAMP production and TSAb activity were measured and cal-culated by stimulating CHO-hTSHR cell line with IgGs of normal control group and Graves" disease ( GD )group. TSAb positive standard was set to more than the mean + 2SD of TSAb activities in control subjects.The positive percentage of TSAb activity in GD group was calculated. Results The cAMP production and TSAb activities of GD group were higher than those of normal group[( 353. 65±126. 34 ) pmol/L vs (237.21±77. 15)pmol/L, ( 149. 08±53. 26)% vs ( 100±32. 52)%, P <0. 05] . The value that higher than 165% was set to be positive for TSAb. The positive percentage of TSAb in GD group was 50% ( 14/28). Conclusion CHO-hTSHR cell line constructed by our group is suitable for detecting TSAb activity in the sera of patients with GD.

OBJECTIVETo compare the clinical efficacy difference in dysantonomia between transcutaneous electrical stimulation at Renying(ST 9) combined with stellate ganglion block(SGB) and simple SGB.

METHODSSixty patients in accord with the diagnostic criteria of dysantonomia were randomly divided into two groups,30 cases in each group. In the observation group,transcutaneous electrical stimulation at Renying(ST 9) combined with SGB were adopted; in the control group,simple SGB was applied. In the two groups, treatment was used three times a week,and nine treatments were considered as one course. There was an interval of one week between courses,and two courses were treated. Total seven weeks were required. Scores were evaluated according to subjective symptoms before treatment,one month and three months after treatment in the two groups.

RESULTSThe scores of subjective symptoms were not statistically different before treatment in the two groups(P>0. 05). The scores of subjective symptoms one month and three months after treatment were all lower than those before treatment(all P< 0. 01), and subjective symptoms scores in the observation group were lower than those in the control group(both P<0. 01).

CONCLUSIONTranscutaneous electrical stimulation at Renying(ST 9) combined with SGB could obviously enhance the clinical effects for dysantonomia, and the control and improvement for clinical symptoms are apparently superior to simple SGB.

Objective To sum up the clinical information and outcomes of one-stage surgical repairs for interrupted aortic arch (IAA) associated with cardiac defects through median stemotomy in infant.Methods From August 2005 to January 2012,23 IAA patients,aged 18 days to 3 years [mean age (8.61 ± 11.81) months],body weight 3.3-13.0 kg [mean (6.61 ± 3.26) kg] were reviewed underwent one-stage repair.There were 12 male and 11 female.The anatomic subtype ineluded type A 20 (87.0％),type B 3 (13.0％),and no type C in the records.All cases included ventricular septal defect and patent ductus artefious,some also with artirical-pulmonary window,aterical septal defect,bicuspid or unicuspid aortic valve,and subvalvular aortic stenosis.Diagnosis was determined in of the patients and suspected in by echocardiography.Also,64 layers helico-CT was employed to make a definite diagnosis for 18 patients and cardiac catheterization was used for 4 patients.All patients with cardiac anomalies underwent one-stage repair through median sternotomy.The aortic continuity was reestablished by anastomosis between the descending aortic segment and aortic arch.Results In all 23 cases,21 were successful.There was 2 (8.69％) postoperative death:one was due to surgical hemorrhage and severe low cardiac output during perioperative stage and the other was 2-month old due to crisis of pulmonary hypertension.CPB time was ranged from 53-215 min [(129.76 ± 38.98) min],and aortic crossclamp time was 34-125 min[(74.47 ± 24.30) min].The length of stay in ICU postoperatively was 96h averagely.The postoperative complications included severe low cardiac output syndrome in 3 patients,hypoxemia in 13,pneumonia in 7,and supraventricular tachycardia in 12.21 patients were followed up from 2 months to 6 years and were in good condition without recoactation.Conclusion The outcomes of early and medium term for one-stage repair of IAA and associated cardiac anomalies through median stemotomy is excellent.Technique of extended anastomosis between the descending aortic segment and aortic arch may reduce the incidence of recoarctation.It is simplified the procedure and improved life quality of patients.

Objective To analyze the complications of radical vaginal hysterectomy in patients with locally bulky cervical cancer.Methods All 258 patients of early cervical cancer (stage Ⅰ A2-Ⅱ A) selected in our hospital during the period of June 2011 to June 2016 undergoing radical vaginal hysterectomy and laparoscopic pelvic lymph node dissection were analyzed.All cases were divided into observation (locally bulky) and control (conventional) groups.Comparison analysis was performed for complications of the two groups and the influence of neoadjuvant chemotherapy on the complications of local bulky patients.Results The incidence of complications in the observation group was 26 cases (27.9％),higher than that in the control group of 28 cases (17.0％),the difference was statistically significant (P ＜ 0.05).The incidence of bladder injury (5 cases vs 2 cases) in observation group was significantly higher than that in control group (P ＜ 0.05).For patients with locally bulky early cervical cancer,the incidence rate of complications of the neoadjuvant chemotherapy group (15.8％) was significantly lower than the simple operation group (36.4％) (P ＜ 0.05).The incidence rate of ureteral injury in neoadjuvant chemotherapy group (0 cases vs 6 cases) was significantly lower than that in simple operation group (P ＜ 0.05).Conclusions Early cervical cancer patients with locally bulky (stage Ⅰ B2/ 1Ⅱ A2) had higher incidence of complications of radical vaginal hysterectomy,and neoadjuvant chemotherapy can reduce the incidence of surgical complications.

Objective To analyze the operation of long-term effect of edge to edge mitral repair for mitral vavle moderateto-severe insufficiency in children retrospectively.Methods Clinical dates of 102 patients who underwent edge to edge mitrel valve repair in Nanjing Children's Hospital from March 2003 to March 2015 were collected.Postoperative thoracic echocardiography was adopted to observe the effect of mitral valve forming and evaluate the follow-up results.Results The whole group of 2 patients died in hospital,Followed up for 1 months to 12 years,during the follow-up of 10 patients were lost.The early fol low-up,medium-term follow-up and long-term follow-up were completed 93,55 and 26 cases,respectively.In the early followup,6 patients had recurrent moderate mitral regurgitation(MR),and 5 patients had recurrent moderate-to-severe MR and reoperated during the follow-up period,a total of 2 cases died.In the medium-term follow up,moderate and severe MR were found in 6 and 4 cases,respectively.Three patients accepted reoperation,two patients died.In the long-term follow-up,1 case had recurrent severe MR,2 cases had re-operation and had no death.Early survival rate was 97.8 ％ (91/93),avoid reoperation rate was 94.6％ (88/93).The incidence of moderate or severe mitral regurgitation was 11.8％ (11/93).Midtcrm survival rate was 96.4％ (53/55),avoid reoperation rate was 94.6％ (52/55),moderate or severe mitral regurgitation rate was 18.2％ (10/55).Long-term follow-up have no death,avoid reoperation rate was 92.3 ％ (24/26),mitral valve moderate and above reflux rate was 7.7 ％ (2/26).The actuarial survival and freedom from MV reoperation rate was (92.4 ± 2.4) ％ and (77.7 ± 6.4) ％ at 10 years,respectively.Conclusion Edge to edge mitral repair in the treatment of children with moderate to severe mitral insufficiency had relatively stable curative effect,relatively fewer complications,and high long-term clinical effect.

Objective:To analyze the differences in 18F-fluorodeoxyglucose (FDG) PET/CT imaging and preoperative localization between patients with temporal lobe epilepsy (TLE) and extratemporal epilepsy (ETLE) caused by focal cortical dysplasia (FCD). Methods:From April 2015 to August 2018, a total of 71 patients (45 males, 26 females, age (24.3±9.1) years) with refractory epilepsy who underwent 18F-FDG PET/CT imaging before surgery and confirmed as FCD by pathology in Xuanwu Hospital were retrospectively analyzed. Patients were divided into TLE and ETLE groups based on pathological results. 18F-FDG PET/CT images were analyzed qualitatively and compared with the operation result, then region of interest (ROI) was used to calculate the asymmetry index (AI), and evaluated the hypometabolism of every cerebral region by |AI| semi-quantitatively. Engle classification were followed-up after surgery. Independent-sample t test and χ2 test were used to analyze data. Results:Of 71 FCD patients, 35 were TLE and 36 were ETLE. The onset age of ETLE patients were younger than TLE patients ((10.1±6.5) vs (14.9±9.7) years; t=2.48, P=0.02). In TLE group, 54.29%(19/35) were completely consistent with the operation results, and 42.86%(15/35) showed hypometabolized brain regions in extratemporal lobe. In ETLE group, 27.78%(10/36) were completely consistent with the operation results, and 47.22%(17/36) showed hypometabolized brain regions in temporal lobe. There were significant differences in the lateral accuracy and positioning accuracy of 18F-FDG PET/CT between TLE and ETLE patients (97.14%(34/35) vs 75.00%(27/36), 54.29%(19/35) vs 27.78%(10/36); χ2 values: 7.19, 6.27, both P<0.05). There was no significant difference in |AI| values between the brain regions of TLE and ETLE patients ( z values: from -1.25 to -0.06, all P>0.05). Conclusion:The lateral accuracy and positioning accuracy of 18F-FDG PET/CT in TLE patients are better than that in ETLE patients.

OBJECTIVE: To assess the value of using flat-sided culture tubes for preparing chromosomes through chorionic villi (CV) and amniotic fluid (AF) cell cultures during prenatal diagnosis. METHODS: From February to March 2020, 157 CV samples and 147 AF samples subjected to prenatal diagnosis at the Maternal and Child Health Care Hospital of Guangxi Zhuang Autonomous Region were selected as the study subjects. For each sample, one flat-sided tube and one flask culture were set up by following the standard protocols. The methods were evaluated by comparing the cell growth, experimental process, quality of chromosome preparation and costs. RESULTS: The success rates for the culturing of CV and AF samples by the flat-sided culture tube method were 97.45% (153/157) and 97.96% (144/147), respectively. By contrast, the success rates for the conventional flask method were 98.72% (155/157) for CV and 98.64% (145/147) for AF samples. No significant difference was found between the two methods (P > 0.05). The average harvest time required by the flat-sided culture tube method was 8.45 days for CV and 9.43 days for AF cultures, whilst the average harvest time for conventional flask method was 9.05 days and 9.54 days, respectively. The flat-sided culture tube method for CV had required significantly shorter average harvest time than the conventional method (P < 0.001). No statistical significant difference was found in the average harvest time for AF by the two methods (P > 0.05). The conventional culturing method had required three containers with two sample transfers. By contrast, the flat-sided culture tube method was carried out in one tube without any sample transfer. The average total amount of medium used was 3.91 mL for each flat-sided culture tube and 6.26 mL for each conventional flask. CONCLUSION The flat-sided culture tube method can provide a simple, cost-effective and error-reducing procedure for the CV and AF samples culture during prenatal diagnosis.

OBJECTIVETo compare the efficacy of thoracoscopic surgery versus thoracotomy in repairing esophageal atresia type Ⅲ with tracheoesophageal fistula (EA/TEF) in neonates.

METHODSA retrospective analysis was conducted in 97 neonates who underwent EA/TEF repair between January 2012 and December 2017 in the Affiliated Children's Hospital of Nanjing Medical University, including 75 patients receiving thoracotomy and 22 patients receiving thoracoscopic surgery. The perioperative data and the incidence of early postoperative complications were compared between two groups.

RESULTSThe operations were completed in all patients. One child (4.5%) in thoracoscopic surgery group was converted to thoracotomy with modified Livaditis procedure due to the long distance of two blind ends (>4 cm) and thinner distal end. The operation time was longer in thoracoscopic surgery group[(143±48) min vs. (120±40) min, <0.05], but the postoperative ventilation time was shorter[(55±22) h vs. (65±19) h, <0.05] and the first oral feeding was earlier in thoracoscopic surgery group[(3.2±1.1) d vs (3.9±1.3) d, <0.05]. No statistical difference was observed in the ratio of red blood cell transfusion, length of hospital stay and drainage tube indwelling time between two groups (all >0.05). The incidence of lung complications in thoracotomy group was higher than that in thoracoscopic surgery group (20.0% vs. 9.1%, <0.01), while there were no significant differences in the incidence of other postoperative complications between two groups. There was no death in thoracoscopic surgery group, while 2 patients died in thoracotomy group.

CONCLUSIONSThoracoscopic repair is a preferred surgical procedure for EA/TEF in neonates.
