ObjectiveTo verify the existing domestic and foreign formulas of normal predictive value indicator for adult pulmonary diffusion capacity’s applicability at current stage in Kunming.MethodsBased on the pulmonary diffusion capacity parameters determination of diffusion capacity for carbon monoxide of the lung (DLCO) collected from one-breath breathing test completed by 680 adults with healthy lung function and without any disease which may cause pulmonary diffusion dysfunctions in Kunming, the regression equation of adult DLCO normal predicted value in Kunming was initially established; the fitting degree of DLCO predicted value and measured value was verified; and the correlation between European adults (instrument-inherent ECCS93) and the normal predicted values of adult DLCO in Shanghai, Chongqing and Lhasa were calculated and contrasted.ResultsThe regression equation of adult DLCO normal predicted value in Kunming was initially established: for male, 0.483+0.063×height (cm)+0.041×weight (kg)–0.071×age (years); for female, 1.679+0.055×height (cm)+0.018×weight (kg)–0.060×age (years). The data collected from the one-breath breathing test were similar to the predicted values obtained from the normal adult male and female DLCO prediction formulas in Kunming, the difference was not statistically significant (tM=–0.167, tF=–0.436, both P>0.05), suggesting that the formula for predicting the value established in this study was valid and well fitted. The predicted value of adult DLCO in Kunming area was statistically significant compared with the adult DLCO estimates of European adults and Lhasa, Chongqing and Shanghai in China (FM=713.4, FF=1 442.2, both P<0.001). Lhasa had the highest value; Kunming was the second highest; instrument-inherent European area and Chongqing came to third and fourth; and Shanghai had the lowest predicated adult DLCO value (all P<0.001).ConclusionThe current predictive formulas for adult pulmonary diffusion capacity indicators in China and worldwide are not suitable for the populations in Kunming.
The symptomatic subluxation of hip is not uncommon in adults, and several kinds of surgical options are available. Twenty-six patients (26 hips) suffering from residual symptomatic subluxation of the hip were treated with innominate osteotomy during 1985 to 1991. The patients were followed-up for 4 to 9 years. The ages of the patients ranged from 22 to 38 years with an average of 26 years and 6 months. The duration of symptoms ranged from 3 to 6 years with an average of 3 years and 5 months. The pertinent prior diseases were the congenital dislocation of hip in 12 cases, Perthes disease in 10 cases, and in the remaining 4 cases, the causes were not identified. The indications for operative intervention were that presence of a reasonable articular cartilaginous space, a reasonable range of motion preserved and particularly a reasnable joint congruity must exist. A new method of re-alignment of the acetabulum was used to placing the ipsilateral foot on the contralateral thigh. The result was evaluated by the symptoms, the function of the hip and the radiographic findings. According to these criteria, the excellent results were obtained in 11 cases and the good result in 15 cases. It was suggested that the innominate osteotomy were also suitable for the treatment of residual symptomatic subluxation of hip in carefully selected adults and the new method of re-alignment of acetabulum was simple and effective.
Objective To summarize the methods of repairingthe urethral defect in the penis of an adult and the clinical application of the island skin flaps of the scrotum septum to the reparative treatment. Methods From January 2000 to November 2005, twenty-six cases of urethral defect in penis, including 16 cases of congenital urethral defect, 6 cases of traumatic urethral defect in middle penis, and 4 cases of distal urethral defect, were repairedby the local penis fascia flaps.The island skin flaps of the scrotum septum were transferred to cover the penis wound. The pedicle contained the artery of the posterior scrotum and the artery of the anterior scrotum. The flap taken from the scrotum septum was 2.5 cm×5.5 cm in area. Results After a follow-up of 7months to 4 years, all the 26 patients had the healing of the first intention without urethral fistula, urethral narrowness or penis curvature, except 4 patients who developedinfection and leakage of urine, but the wounds healed spontaneously 2-4 weeks after operation. Conclusion The penis fascia flaps and the island skin flaps of the scrotum septum can be used to repair the urethral defect in the penis of an adult. The blood supply to the flaps is sufficient and all theflaps can survive well. A good shape and function of the penis can be obtained.
【Abstract】ObjectiveThe growing gap between the number of patients waiting for transplantation and available organs has continued to be the number one issue facing the transplant community. The major limitation of adult-to-adult living donor liver transplantation (LDLT) is the adequacy of the graft size. But donor safety is the major concern in LDLT. Methods Two patients with end-stage liver disease were successfully performed adult-to-adult LDLT using dual grafts in our division. One patient’s donors are left lobe and left lobe from his two old sisters , respectively. The other graft are right lobe from his 56 years-old mother and left lobe splitting from a cadaveric organ donor (the other part of split-liver transplants from the the cadaveric organ donor offer to another adult donor ). Results Both recipients and three donors display good graft function and normal triangularshape regeneration of their liver grafts after liver transplantation. There was neither a mortality nor a serious complications in the donors. Conclusion The critical issue of LDLT is donor morbidity. Dual grafts from two living donors can help to alleviate the problem of small-for-size grafts and yet secure the safety of the donor. But the complicated surgical technique give a great challenge for liver transplant surgeons.
ObjectiveTo measure L1-L5 lumbar isthmus thickness and to construct Chinese adult male lumbar (L1-L5) 3D model by Micro CT 3D reconstruction technique, in order to provide micro-anatomical data for clinical treatment of L1-L5 lumbar spondylolysis.
MethodsDry, non-damaged specimens of L1-L5 lumbar isthmus from 60 Chinese adult males were randomly selected from September 2013 to January 2014. Micro CT scanning was carried out, followed by corresponding 3D model construction. The microscopic anatomical parameters such as superior, inferior, inner and outer edge thickness of left and right L1-L5 lumbar isthmus were measured.
ResultsL1-L5 lumbar isthmus superior edge thickness was in the order of L1> L2> L3> L5> L4, with the variation ranging from (4.31±0.95) mm to (4.88±0.75) mm. L1-L5 lumbar isthmus inferior edge thickness was in the order of L1< L2< L3< L4< L5, gradually thickened with the variation ranging from (6.03±1.01) mm to (7.27±1.27) mm. L1-L5 lumbar isthmus inner edge thickness amplitude was not obvious, ranging from (6.33±1.21) mm to (6.57±1.27) mm. L1-L5 lumbar isthmus outer edge thickness was in the order of L1< L2< L3< L4< L5, gradually thickened with the variation ranging from (8.44±1.21) mm to (10.27±1.28) mm.
ConclusionThere are certain rules within superior, inferior, inner and outer edge thickness of adult L1-L5 lumbar isthmus:the inferior and outer edge thickness of L1-L5 lumbar isthmus gradually becomes thicker, while superior edge gradually becomes thinner. From L1 to L5 lumbar isthmus, the outer edge of the lumbar isthmus is the thickest, followed by inner and inferior edge, and the upper edge is the thinnest.
ObjectiveTo sum up the diagnosis and treatment of adult ileal duplication with clinical cases from Peking Union Medical College Hospital (PUMCH). MethodsSix cases of adult ileal duplication admitted in our hospital from February 1996 to December 2010 were analyzed. Different assistant investigations were supposed to different patients due to the chief complaints including gastroscope, colonoscopy, abdominal CT scan, arteriography, 99Tcm radionuclide imaging, and double-balloon intestinal endoscope. None was made a definite diagnosis before operation with only one uncertain case. All cases received operation and pathological examination. Results All cases admitted were male. The chief complaints included intestinal bleeding, abdominalgia, intestinal obstruction, and abdominal mass. Five out of six patients received gastroscope, colonoscopy, and abdominal CT scan while three received mesenteric arteriography, but none was found any suggestion for ileal duplication. Even 99Tcm radionuclide imaging pointed out only two with abnormal abdominal bleeding. Three received doubleballoon intestinal endoscope, paying attention that only one discovered with ileal duplication. In a concluding, none was made a definite diagnosis before operation with only one uncertain case. All the cases received operation. The duplications of ileum in the length of 6-25 cm were found at the site of 11-100 cm proximal to ileocecum during the operation. Pathological report confirmed the clinical diagnosis of all cases with adult ileal duplications． Two cases were found with ectopic gastric mucosa, another two with diverticulum, and one with ectopic pancreas， in addition the remaining with inflammatory fibrous pseudotumor. Prognosis were good for all after operation. ConclusionsIleal duplications are rarely seen in adults, gender prefer male． Without specific clinical symptoms and inspections, definite diagnosis before operation is hard to make. But maybe doubleballoon intestinal endoscope and 99Tcm radionuclide imaging can give out positive result. Surgeons should be aware of this condition when performing abdominal exploration. Once discovered, resection is necessary.
Objective
To review the progress in clinical and biomechanical study on soft tissue reconstruction of adult-acquired flatfoot deformity (AAFD).
Methods
The recent original articles of soft tissue repair and tendon transfer for AAFD were extensively reviewed.
Results
The soft tissue procedures for AAFD can be divided into two components: static restoration of medial column stability and dynamic reconstruction of the posterior tibial tendon. The most important static structure to be repaired for AAFD is the spring ligament. On the other hand, various methods can be used for dynamic reconstruction. The flexor digitorum longus transfer is widely used, but results of biomechanical studies do not support the advantage of this method. For patients having normal function of the posterior tibial muscle, the Cobb procedure may be more suitable.
Conclusion
The soft tissue reconstruction procedures of AAFD should be chosen individually based on the stage and type of the deformity.
【Abstract】 Objective To summarize techniques of the total hi p arthroplasty (THA) in the treatment of developmental dysplasia of the hi p (DDH) with severe osteoarthritis in adults. Methods From March 2000 to January 2006, 24 patients (27 hips) with DDH were treated by THA with an cementless cup. There were 7 males and 17 females, withthe average age of 49.6 years (ranging from 26 years to 63 years). Unilateral DDH occurred in 21 patients and bilateral DDH occurred in 3 patients. Based on the Crowe classification, there were 16 hips in 15 patients of type I, 4 hips in 4 patients of type II, 4 hips in 3 patients of type III, 3 hips in 2 patients of type IV. Except for 3 patients with bilateral DDH, the other patients’ ill lower l imbs were 2-7 cm shorter than the healthy lower ones. Results All the patients were followed up from 9 months to 6.5 years and no one had infection, dislocation, femur fracture and so on after the operation. In 18 patients, the pain was completely rel ieved and the function of the hip joints was good. After the gluteus medius exercise, the claudication of 3 patients after the operation disappeared. In 3 patients, the ill lower l imbs were more than 1 cm shorter than the healthy lower ones and the other patients’ ill lower l imbs were less than 1 cm shorter than the healthy lower ones. Two patients’ lower l imbs were been lengthened 4-5 cm. All the patients’ sciatic nerves were not injured. The Harris scores were 46.5 ± 7.2 preoperatively and 84.0 ± 5.7 postoperatively (P lt; 0.05). Conclusion THA with deepening the medial wall of the acetabulum at the true acetabulum and choosing small cementless cup in adult could obtain favorable results.
Abstract： Objective To investigate the clinical results of offpump anatomic surgical repair for complex coarctation in adults. Methods We retrospectively analyzed the clinical data of 7 patients with complex coarctation who underwent onestage anatomic surgical repair between January 2005 and December 2008 in Fu Wai Hospital. There were 5 males and 2 females with the age ranged from 16 to 41 years, average at 24.4 years. Among all the patients, there were 2 patients of coarctation with hypoplastic aortic arch, 1 of coarctation with aortic arch aneurysm, 3 of coarctation with descending thoracic aortic aneurysm, and 1 of coarctation with B type aortic dissection. All patients were diagnosed by color echocardiography, CT or agnetic resonance imaging（MRI）. All off-pump operations were performed under general anesthesia and ambient temperature. Median sternotomy was performed in 1 patient and left thoracotomy in 6 patients. Aortic arch patching enlargement was performed in 4 patients and descending thoracic aorta replacement in 3 patients (including 1 combined with abdominal aorta replacement and 1 case of Stanford B type aortic dissection, trunk stent was transplanted at the same time). Results There was no hospital mortality or severe surgical complications. Seven patients were followed up for a period ranged from 6 to 49 months with an average time of 20.1 months. No late death or recoarctation occurred. Hoarseness occurred in one patient and presented no improvement during the 11 months follow-up. Conclusion Onestage offpump anatomic surgical repair is safe and feasible in treating adult patients with complex coarctation, and it shows a good immediate and longterm result.
OBJECTIVE: To explore the expression of basic fibroblast growth factor(bFGF) during the wound healing of human fetal and adult skin and its significance. METHODS: We established the animal model of fetal scarless healing by transplanting full-thickness skin grafts from human fetus to a subcutaneous location on the athymic mouse recipient, and then making the linear incisions. The expression of bFGF was observed in the normal adult skin, normal fetal skin and during wound healing by immunohistochemical method. The positive staining cells were counted under selected high-power focus randomly. RESULTS: bFGF staining was not observed in the normal fetal skin and the wounded one. However, bly positive staining was shown around the vessels in normal adult skin. Moreover, the positive straining became ber in the wounded skin, especially in dermal fibroblasts and endotheliocytes. The number of positive staining cell was 2.1 +/- 0.1 in normal fetal skin, and 2.2 +/- 0.1, 2.1 +/- 0.3, 2.1 +/- 0.3 and 2.0 +/- 0.1 in the fetal skins after 12 hours, 1 day, 3 days and 7 days of wound respectively. The number of positive staining cell were 23.2 +/- 4.2 in normal adult skin and 40.5 +/- 3.6 in the wound adult skin. There was significant difference between the fetal skin and adult skin (P lt; 0.01). CONCLUSION: The negative expression of bFGF in the fetal skin may be one of the important reasons for fetal scarless healing.
