Objective To evaluate the value of CT in diagnosis of cervical intervertebral disk herniation. Methods The observation of CT appearances of 146 cases and the size, type, position of cervical intervertebral disk herniation were analyzed. Results ①Cervical intervertebral disk herniation was always multi-segments,often lolated at C4,5and C5,6. ②C5,6was mostly seen (142 cases,97.3%). ③Among centric and lateral type,centic type was mostly seen { 135 cases,92.5%). ④Of 135 cases of centric type,54 cases were mild type (< 2 mm) ,66 cases were moderate type (2 ～ 4 mm) , 15 cases were severe type (> 4 mm). Conclusion CT scan is convenient, efficient,accuracte and the first choice method in diagnosing cervical intervertebral disk herniation.

ObjectiveTo compare the outcomes and indications between exchange nailing (EN) and augmentation plating (AP) with a nail left in situ for femoral shaft hypertrophic nonunion after femoral nailing. MethodsFrom April 1998 to June 2009, 20 patients with femoral shaft hypertrophic nonunions after femoral nailing were treated with EN (11 patients) and AP (9 patients) respectively. There were no significant differences between the two groups with respect to the patient's age, gender, associated injuries, anatomical location and type of femoral fracture. Patients were evaluated by imaging and clinical function at 1, 2, 3, 4,6, and 12 months after surgery, and then every year postoperatively, to observe the callus and the recovery condition of the affected limb function. Fisher exact test and t'-test were performed to compare the outcome and complications respectively. ResultsAn unpaired t'-test showed no significant differences with respect to follow-up time, operating time, intraoperative blood loss, postoperative drainage, length of stay, time to radiographic union, time to clinical union, and AAOS score between the two groups. The cost of hospitalizations in the EN group was higher than in the AP group(t'=16.4, P=0.013). Four nonunions in the EN group failed to achieve union, which 3 patients were subsequently treated with AP and simultaneous autogenous bone grafting and 1 patient was treated with nail dynamization. All 9 hypertrophic nonunions in the AP group obtained osseous union. Fisher exact test showed a higher nonunion rate of EN compared with AP (χ2=6.01 ,P=0.008). ConclusionEN has been an excellent choice for aseptic isthmal femoral nonunion without a large bone defect subsequent to intramedullary fracture fixation, and AP can be an effective solution in cases of nonisthmal femoral nonunion and bone defect and failed exchange nailing.

The article has reviewed theShengyang-Yiweidecoction for the disease of digestive system, such as diarrhea-predominant pattern irritable bowel syndrome(D-IBS), chronic gastritis, diabetic gastric paralysis (DGP), ulcerative colitis (UC) and chronic diarrhea. Recently,Shengyang-Yiwei decoction was also used in some other diseases, such as diseases of urinary system, diseases of nervous system, orthopedic diseases, gynecological diseases and so on. This review aimed to provide reference and evidence for the clinic application ofShengyang-Yiwei decoction.

Objective To investigate the operative indications and operation techniques for augmentative plate fixation in treatment of femoral shaft atrophic nonunions subsequent to intramedullary fixation. Methods Twelve femoral nonunions after internal fixation with intramedullary nailing were treated with augmentative plate internal fixation and bone graft from June 1999 to June 2008. All femoral nonunions were caused by insecure fixation of the intramedullary nailing, in which a rotational instability of the fracture site was verified in all the patients during operation. Minimally invasive removal of the granulation tissue at fracture site and the sclerotic bone was dccorticated. The adequate lilac bone was tiled longitudinally on the nonunion gap and the cortical bone bed. The fixation involved the limited-contact dynamic titanium plate with 5-6 holes, 3.0 mm Kirschner wire and 4-6 double cortex cortical screw fixation.Protective weight-bearing was given after surgery and the tunction was evaluated at 1,3, 6 and 12 months with imaging. Results All patients were followed up for 7-26 months ( average 17.4 months), which showed radiological solid union (7-12 months, average 9.4 months) and clinical union (5-9 months, average 7.1 months ). The operation lasted for 50-120 minutes ( average 77.5 minutes), with blood volume of 150-350 ml ( average 252 ml). There were nine patients with bone pain, of whom the pain was relieved within one month in seven patients and three months in two. No infection, hardware loosening or breaking were found. Conclusion The plate augmentation and cancellous bone grafting leaving the nail in situ can be an effective solution for nonisthmal femoral nonunion, bone defect and failed exchange nailing.

Objective     To summarize the surgical treatment experience in neonates with coarctation of the aorta (CoA) and aortic arch hypoplasia (AAH). Methods     The neonates with CoA and AAH who underwent surgical treatment in the Department of Pediatric Cardiac Surgery of Guangdong Provincial People's Hospital from 2013 to 2020 were retrospectively enrolled. The postoperative complications, long-term survival rate, and freedom from aortic reobstruction were analyzed. Patients undergoing extended end-to-end anastomosis were allocated into an extended end-to-end group, those undergoing extended end-to-side anastomosis into an extended end-to-side group, and those undergoing pulmonary autograft patch aortoplasty into a patch aortoplasty group. Results     Finally 44 patients were  enrolled, including 37 males and 7 females, aged 5.00-30.00 (19.34±7.61) days and weighted 2.00-4.50 (3.30±0.60) kg. There were 19 patients of extended end-to-end anastomosis, 19 patients of extended end-to-side anastomosis, and 6 patients of pulmonary autograft patch aortoplasty. The mean values of the Z scores of the proximal, distal, and isthmus of the aortic arch were –2.91±1.52, –3.40±1.30, and –4.04±1.98, respectively. The mean follow-up time was 45.6±3.7 months. There were 2 early deaths and no late deaths. Aortic reobstruction occurred in 8 patients, and 3 patients underwent reoperation intervention. The 5-year rate of freedom from reobstruction was 78.8%. The Cox multivariable regression analysis showed that the related factors for postoperative reobstruction were the Z score of the preoperative proximal aortic arch (HR=0.152, 95%CI 0.038-0.601, P=0.007) and the postoperative left main bronchus compression (HR=15.261, 95%CI 1.104-210.978, P=0.042). Conclusion     Three surgical procedures for neonates with CoA and AAH are safe and effective, but the aortic reobstruction rate in long term is not low. The smaller Z score of the preoperative proximal aortic arch and the postoperative left main bronchus compression are risk factors for long-term aortic reobstruction.
