OBJECTIVETo compare the therapeutic effects between close reduction and plaster slab fixation combined with plaster external traction and operation for the treatment of pediatric closed Gartland type III supracondylar humerus fractures without neurovascular injury complications.

METHODSFrom June 2009 to June 2012, 151 children with closed Gartland III supracondylar humerus fractures were retrospectively studied and divided into two groups, including 87 boys and 64 girls, ranging in age from 1 to 12 years old with an average of 5.3 years old. Among them, 76 children (conservative group) were treated with close reduction and plaster slab fixation combined with plaster external traction; 75 children (operation group) underwent surgical operation. The time of elbow joint function exercise, the healing time of fracture, the function recovery of elbow joint and carrying angle was recorded and analyzed. The therapeutic effects were evaluated by the Flynn criteria system.

RESULTSAll patients were followed up from 6 to 36 months (18.3 months on average). The average time of fracture healing and elbow joint functional exercise of the conservative group was shorter than those of operation group (P < 0.001). Motion range of the elbows and carrying angle of two groups were no statistical difference (P > 0.05). According to Flynn criteria system, in conservative group, the result was excellent in 31 cases, good in 35, fair in 7, and poor in 3; in operation group, 27 in excellent, 30 in good, 17 in fair and 1 in poor; there was no significant difference between two groups in therapeutic effects (P > 0.05).

CONCLUSIONClose reduction and plaster slab fixation combined with plaster external traction in treatment of pediatric closed Gartland type III supracondylar humerus fractures without neurovascular injury complications,which has similar effect to surgical treatment, and the time of fracture healing and elbow joint function exercise are significantly shorter.

Objective To examine the clinical effect and learning curve of endoscopic thyroidectomy via chest-areolar approach in the treatment of benign thyroid nodules. Methods From January 2012 to May 2016,49 patients underwent endoscopic thyroidectomies via chest-areolar approach in Xuanwu Hospital ,Capital medical university. The clinical characteristics ,prognosis and operation time were retrospectively analyzed. The patients were divided into 9 groups according to the surgical sequence ,and the learning curves were analyzed by using moving average method. Results 49 endoscopic thyroidectomies via chest-areolar approach were performed successfully. The average size of the nodules was(2.80 ± 0.62)cm. 10 patients underwent bilateral thyroidectomy and 39 underwent unilateral thyroidectomy. The average operation time was(157.49 ± 21.23)min. 2 cases received re-operation due to postoperative pathology of malignancy. There were no postoperative recurrent laryngeal nerve injuries. 11 patients suffered from asymptomatic hypocalcemia with parathyroid hormone in the normal range. All of the patients were satisfied with the cosmetic results. The learning curves indicated that 35 endoscopic thyroidectomies were needed to be performed in the early study stage. Conclusions For surgeons with experience of conventional thyroidectomies,endoscopic thyroidectomy via chest-areolar approach is feasible and safe for selected patients. There is a significant learning curve in the application of endoscopic thyroidectomy. In the early study stage of endo-scopic thyroidectomy,35 cases are basically required for beginning surgeons to practice the surgical operation.

OBJECTIVETo compare differences of clinical therapeutic effect of heat-sensitive moxibustion with different doses for irritable bowel syndrome (IBS).

METHODSSixty cases of IBS were randomly divided into a saturated-dose group (30 cases) and a traditional-dose group (30 cases). Heat-sensitive moxibustion was applied in both groups. The acupoints that had the strongest heat-sensitive feeling were selected and treated by warm and suspended moxibustion with moxa stick. Disappearance of heat-sensitive feeling was taken as the sign of treatment time in the saturated-dose group, while the traditional-dose group was treated for 15 min each time. The treatment in both groups was given twice a day for first 5 days, and from the sixth day it was given once a day for continuous 25 times, totally 30 days. Clinical symptom scores and therapeutic effect before and after treatment in two groups were observed.

RESULTSAfter the treatment, the cured and markedly effective rate was 75.0% (21/28) in the saturated-dose group, which was inferior to 44.4% (12/27) in the traditional-dose group (P < 0.05). The clinical symptom scores, including diarrhea, abdominal distension and pain, were obviously reduced in two groups compared with those before the treatment (all P < 0.05). Compared with the traditional-dose group, the symptom scores of diarrhea and abdominal distension in the saturated-dose group were obviously decreased (0.87 +/- 0.13 vs 1.27 +/- 0.21, P < 0.01; 1.12 +/- 0.41 vs 1.32 +/- 0.26, P < 0.05).

CONCLUSIONThe moxibustion featured with disappearance of heat-sensitive feeling and saturated dose has better therapeutic effect than that with traditional-dose for treatment of IBS. As individual dynamic amount of moxibustion, disappearance of heat-sensitive and quantitation varies from person to person, which is one of the key factors to obtain the best curative effect.

This paper is aimed to study the effects of nitrogen form on the growth and quality of Chrysanthemums morifolium at the same nitrogen level. In order to provide references for nutrition regulation of Ch. morifolium in field production, pot experiments were carried out in the greenhouse at experimental station of Nanjing Agricultural University. Five proportions of ammonium and nitrate nitrogen were set up and a randomized block design was applied four times repeatedly. The results showed that the growth and quality of Ch. morifolium were significantly influenced by the nitrogen form. The content of chlorophyll and photosynthesis rate were the highest at the NH4(+) -N /NO3(-) -N ratio of 25:75; The activities of NR in different parts of Ch. -morifolium reached the highest at the NH4(+) - N/NO3(-) -N ratio of 0: 100. The contents of nitrate nitrogen in the root and leaves reached the highest at the NH4(+) -N/NO3(-) -N ratio of 50:50. The activities of GS, GOGAT and the content of amylum increased with the ratio of NO3(-) -N decreasing and reached it's maximum at the NH4 + -N/NO3 - -N ratio of 100: 0. The content of ammonium nitrogen were the highest at the NH4 + -N /NO3 --N ratio of 75: 25, while the content of soluble sugar reached the highest at the NH4(+)-N/NO3(-) -N ratio of 25: 75. The content of flavones, chlorogenic acid and 3,5-O-dicoffeoylqunic acid were 57.2 mg x g(-1), 0.673% and 1.838% respectively, reaching the maximum at the NH4(+) -N /NO3(-) -N ratio of 25:75; The content of luteoloside increased with the ratio of NO3(-) -N increasing and reached it's maximum at the NH4(+) -N/NO3(-) -N ratio of 0: 100. The yield of Ch. morifolium reached it's maximum at the NH4(+) -N /NO3(-) -N ratio of 25:75. Nitrogen form has some remarkable influence on the nitrogen metabolism, photosynthesis and growth, Nitrogen form conducive to the growth and quality of Ch. morifolium at the NH4(+) -N /NO3(-) -N ratio of 25: 75.
