OBJECTIVE: To explore the pluripotential and possible clinical application of adult stem cells. METHODS: The original articles on adult stem cells were extensively reviewed and the recent advances were summed up. RESULTS: Adult stem cells were located at different tissues of human beings and had the pluripotentiality of self-renewal and differentiation. Some adult stem cells, such as in marrow, nerve, muscle, fat, skin, liver, tissues, had the ability to differentiate into the unrelated cell type. CONCLUSION: The pluripotential, ubiquitous distribution and plasticity of adult stem cells offered a new way in regeneration medicine, such as cell therapy and tissue engineering.
Objective To provide evidence-based therapeutic schedule for an adult patient with Lumber Isthmic Spondylolisthesis grading II. Methods Based on fully assessing the patient’s conditions, the clinical problems were put forward according to PICO principles. Such database as The Cochrane Library (2005 to April 2011), DARE (April 2011), CENTRAL (April 2011), MEDLINE (April 2011), EMbase and CBM were searched to collect high quality clinical evidence, and then we told a patient information about treatment plans. The plan was chosen by the patient for she knew her conditions and the plans. Results We included 1 meta-analysis, 3 randomized controlled trials, 5 systematic reviews and 1 prospective study on the natural course of isthmic spondylolisthesis were included. Literature evidence indicated that the prognosis of isthmic spondylolisthesis was good. Surgery should be selected when there was neither no remission of symptom, nor progression of lumber olisthy with conservative treatment. The long-term effect of surgery may be good, but it cannot change the natural course of the disease. Based on literature evidence, the patient chose the conservative treatment. After one year’s treatment the patient recovered, her sciatica relieved, and CT showed no progression of lumber olisthy. Conclusion Patient with low grand isthmic spondylolisthesis chose conservative treatment may achieves good effects, whereas on the process of the treatment, regular follow-up to monitor the progression of lumber olisthy should be conducted.
To evaluate the development prevention and treatment of pneumonic injury after operation on aged patients with abdominal infection. We analyzed 77 aged patients (＞60 y) admitted from Jan. 1991 to Dec. 1992: 38 cases of which with abdominal infection (infection group), 39 cases without abdominal infection (non-infection group). All patients were given oxygen therapy and continuous SaO2 monitoring. Results: There were 28 patients with hypoxemia (SaO2＜95%) in infection group, with an occurrence rate of 73.7%. In non-infection group (12 patients), the rate of hyoxemia was 30.8%, which has significant difference between two groups (Ｐ＜0.001). All patients with hypoxemia were given oxygen therapy and 31 patients′ SaO2 was elevated. The efficient rate was 77.5%. Other 9 patients developed ARDS, the rate was 2.5% (9/40). In the infection group 8 patients developed ARDS with an occurrence rate of 21.1%. There was one patient with ARDS in the non-infection group, the rate was 2.6%. There was significant difference between two group (Ｐ＜0.05). Conclusions: The results suggest that hypoxemia is liable to occur in aged patients with abdominal infection after operation and these patients were liable to develop ARDS. Oxygen therapy and SaO2 monitoring is the important managements to these patients in prevention of pneumonic injury.
Objective To explore the sonographic features of testicular torsion in adult males (≥25 years). Method We retrospectively analyzed the clinical, pathological and sonographic data of 79 adult male patients with testicular torsion, in whom 20 underwent resection of testis and 59 retained testis in West China Hospital from September 2006 to March 2017. Results There were 56 patients with spermatic cord nodules or mass with the largest mass of about 36 mm ×31 mm; the scrotal wall thickened in 48 patients with the thickness of 5–10 mm; axial changes of the affected testis were found in 24 patients; there were 61 patients with testicular growth in the affected side, while the affected testis was reduced in 7; there were 67 patients with asymmetric echo in the affected side, and the maximum hypoechoic area was about 36 mm×26 mm; the epididymis of the affected side in 35 patients with were unclear, and the epididymis of the affected side was enlarged in 19; 25 patients had hydrocele of testis; there was no blood flow in 49, blood flow reduced in 25, and blood flow increased in 5. Four patients were diagnosed by contrast-enhanced ultrasound, and there was no enhancement in 3 and partial enhancement in 1. Conclusion The sonographic features of testicular torsion in adult males are obvious, and the early diagnosis of testicular torsion can be confirmed by contrast-enhanced ultrasonography.
ObjectiveTo evaluate the application value and significance of pulse indicator continuous cardiac output (PiCCO) in perioperative treatment of adult congenital heart disease (ACHD). MethodsBetween June 2014 and June 2015, 100 adult patients (44 females and 56 males) underwent congenital heart disease operation. Patients were randomly divided into a PiCCO group and an experience treatment (control) group. According to the data of PiCCO detection, the PiCCO group was treated with vasoactive drugs and liquid balance management, the control group was treated by routine monitoring data. The clinical effectiveness of the two groups was compared. ResultsThe ventilator time, ICU time and length of stay in the PiCCO group were significantly shorter than those in the control group with statistical differences (P=0.02, 0.03, 0.04). The drug dosage (dopamine, milrinone) during ICU were higher in the PiCCO group than those in the control group (P<0.01, P=0.04). There was no mortality in both groups. No significant difference was found in the incidence of postoperative complications between the two groups (P>0.05). ConclusionThe application of PiCCO in the perioperative treatment of adult congenital heart disease can promote the early recovery of ACHD patients, and has a certain safety and effectiveness. Actively vasoactive drugs application to maintain circulation early in ICU has positive effect on the patient's recovery.
Sepsis is not only a common critical disease , but also a common complication and cause of death of patients in intensive care unit. It has the characteristics of dangerous condition, rapid development and high mortality. How to treat sepsis to improve the prognosis and quality of life of patients is very important. Timely and reasonable anti-infection is a vatal part in the treatment of sepsis. This article will review the progress of anti-infective therapy in adult patients with sepsis, starting from empirical anti-infection, procalcitonin-guided anti-infection, bacterial culture combined drug sensitivity test-guided anti-infection and anti-infection with antimicrobial peptides, aiming to provide a certain basis and reference for the anti-infective treatment of adult sepsis.
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.

This review summarized the current status of diagnosis and treatment of viral pneumonia in adults so as to improve our understanding of it.
Objective To review the effects of pulmonary surfactant in adult patients with acute lung injury ( ALI) /acute respiratory distress syndrome ( ARDS) . Methods Randomized controlled trials ( RCTs) were recruited from PubMed ( 1966.1-2011.3) , ISI Web of Knowledge ( all the years) and Wanfang Database ( 1982-2011) . Related published data and attached references were hand searched. All the RCTs about pulmonary surfactant for the adult patients with ALI/ARDS were included, then a meta-analysis was performed. Results Eight eligible trials were enrolled. Pooled analysis showed that treatment with pulmonary surfactant was not associated with reduction in 28 or 30-day mortality compared with the control group [ OR 1.05, 95% CI ( 0.90, 1.22 ) , P = 0.55] , neither did subgroup analysis in the pneumoia/ aspiration, sepsis, and trauma/ surgery induced ALI/ARDS patients. Three RCTs showed the oxygenation was significantly improved in adult ALI/ARDS patients receiving pulmonary surfactant compared with the control group( Plt;0.05) . Shorter mechanical ventilation days was shown in the ALI/ARDS patients receiving pulmonary surfactant in one RCT(Plt;0.05) . Conclusions Meta-analysis showed pulmonary surfactant did not reduce the 28 or 30-day mortality of adult patients with ALI/ARDS, however, improved the oxygenation. Pulmonary surfactant can be considered a therapy in ALI/ARDS.
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.
