  • Traditional Chinese Medicine for Essential Hypertension: An Overview of Systematic Reviews

    ObjectiveTo evaluate the methodological bias and the reliability of the conclusions of systematic reviews (SRs) about traditional Chinese medicine for essential hypertension. MethodsWe comprehensively searched PubMed, EMbase, The Cochrane library (Issue 4, 2014), CBM, CNKI and WanFang Data to collect SRs of traditional Chinese medicine for essential hypertension from the establishment time of databases to April 30th, 2014. The AMSTAR tool was applied for methodological quality assessment of included studies, and the GRADE system was applied for evidence quality assessment of included outcomes of SRs. ResultsA total of 12 SRs involving 31 outcomes were included, of which 11 SRs focused on the comparison of therapeutic effects between traditional Chinese medicine combined with western medicine and western medicine alone. Nine SRs adopted Jadad tool to assess methodological quality of included original studies. The results of assessment using AMSTAR showed that, among 11 items, there were the most problems concerning Item 1 "Was an 'a prior' design provided?" (none of the 12 SRs provided it); followed by Item 11 "Were potential conflict of interest included?" (nine SRs didn't described it), and Item 6 "Were the characteristics of included studies provided" (six SRs didn't provided it). The results of grading showed that, 29 outcomes were graded as "low" or "very low" quality. The main factors contributed to downgrading evidence quality were limitations (31 outcomes), followed by imprecision (12 outcomes), and inconsistency (13 outcomes). ConclusionCurrently, the methodological quality of SRs about traditional Chinese medicine for essential hypertension was poor on the whole, with low quality of evidence as well as lack of enough attention to the end outcomes of patients with essential hypertension. Thus, physicians should apply the evidence to make decision about traditional Chinese medicine for essential hypertension with caution in clinical practice.

  • Effectiveness of External Application with JinHuang Powder for Diabetic Foot Ulcers: A Systematic Review

    ObjectiveTo systematically evaluate the potential effectiveness of JinHuang powder in the treatment of diabetic foot ulcers (DFUs). MethodsDatabases including PubMed, The Cochrane Library, Web of Science, CBM, WanFang data, VIP and CNKI were electronically searched from their inception to December 2013, to identify randomized controlled trials (RCTs) about JinHuang powder for DFUs. Two reviewers screened literature according to the inclusion and exclusion criteria, extracted data and assessed the methodological quality of included studies, and then meta-analysis was performed by using RevMan 5.1 software. ResultsA total of 3 RCTs involving 198 patients were included. The results of meta-analysis showed that:the JinHuang powder group were superior to the control group in total effective rate (RR=1.25, 95%CI 1.10 to 1.41, P=0.00) and the wound healing time (SMD=-3.32, 95%CI -5.69 to -0.96, P=0.00). ConclusionCurrent evidence suggests that the JinHuang powder is an effective therapeutic method for DFUs. Because of the limitations of quantity and quality of the eligible studies, large sample size studies are needed to validate the conclusion.

  • AN EXPERIMENTAL STUDY ON REPAIR OF FULL THICKNESS SKIN WOUND WITH GRAFT OF AUTOLOGOUS KERATINOCYTE SUSPENSION IN RATS

    ObjectiveTo investigate the application of autologous keratinocyte suspension transplantation in skin reconstruction. MethodsForty adult Sprague Dawley rats (weighing, 210-230 g) were randomly divided into 4 groups (n=10): high density keratinocyte suspension transplantation (1×106 cells/cm2) group (group A), middle density (1×105 cells/cm2) group (group B), low density (1×104 cells/cm2) group (group C), and control group (group D). Skin samples were harvested from the rats in groups A, B, C for the isolation of keratinocytes. The model of anti-contracture of full thickness skin wound was made in rats and autologous keratinocyte suspension was transplanted into the wound. The wound was covered by the allogeneic skin (allogeneic skin derived from Wistar rats). The survival of rats was observed after operation. The survival of allogeneic skin was observed at 7, 14, and 21 days after operation, and wound healing rate was calculated after allogeneic skin dropped off. Histological staining and immunohistochemical staining were carried out at 21 days after operation. ResultsAll the rats survived to the end of the experiment. The allograft skins survived in all groups, dried and dropped off. The epithelium sheet could be seen in groups A and B at 21 days, a few very thin epithelium in group C, and no epithelization in group D. The wound healing rate of groups A (62.9%±9.6%) and B (64.2%±9.1%) were significantly higher than that of groups C (38.5%±5.7%) and D (22.7%±5.5%) (P<0.05), and significant difference was found between groups C and D (P<0.05), but there was no significant difference between groups A and B (P>0.05). The results of histological observation showed that squamous epithelial cells were observed in groups A, B, and C, but not in group D; obvious layers of epidermis were observed in groups A and B, thin epidermis and inflammatory cell infiltration in group C, and granulation tissue in group D. The immunohistochemistry staining showed that the expressions of collagen type IV and collagen type VII in groups A, B, and C; the percentage of collagen type IV and collagen type VII positive cells in groups A and B were significantly higher than that of group C (P<0.05), but there was no significant difference between groups A and B (P>0.05). The expressions of collagen type IV and collagen type VII in group D were negative. ConclusionThe repair of full thickness skin wound with graft of autologous keratinocyte suspension can achieve reconstruction of the skin. The appropriate density of keratinocyte suspension for wound healing is 1×105 cells/cm2.

  • Modified Fontan Procedure for Complex Congenital Heart Diseases

    ObjectiveTo review our clinical experience of modified Fontan procedure for complex congenital heart disease (CHD) in children. MethodsClinical data of 62 children with complex CHD who underwent modified Fontan procedure in Guangzhou Women and Children's Medical Center from May 2008 to December 2013 were retrospectively analyzed. There were 41 male and 21 female patients with their median age of 4 years(range, 16 months to 14 years) and body weight of 12.5 (8.9-49.5) kg. Diagnosis included functional single ventricle in 45 patients, transposition of the great arteries (TGA) with ventricular septal defect (VSD) and left ventricular outflow tract obstruction (LVOTO) in 6 patients, corrected TGA with VSD and LVOTO in 6 patients, double outlet right ventricle with severe pulmonary stenosis in 4 patients, and right ventricular dysplasia in 1 patient. Previous procedure included pulmonary artery banding in 10 patients, unilateral bidirectional Glenn shunt in 37 patients, and bilateral bidirectional Glenn shunt in 8 patients. Seventeen patients received single-stage modified Fontan procedure, and 45 patients received two-stage modified Fontan procedure. Extracardiac conduit was used in 56 patients, and lateral tunnel was used in 6 patients. Concomitant procedures included fenestration in 41 patients, atrioventricular valvuloplasty in 6 patients, and pulmonary artery angioplasty in 3 patients. ResultsTwo patients in both single-stage and two-stage groups died postoperatively with mortality of 11.8% and 4.4% respectively (P=0.299). Postoperative mechanical ventilation time, length of ICU stay, chestdrainage duration, postoperative hospital stay and morbidity were not statistically different between single-stage and two-stage group. Mean follow-up was 2.0 ±0.5 years (range, 3 months to 5 years). There were 2 late death in the singlestage group but no late death in the two-stage group. Growth of all survival children was good, and their exercise capacity significantly improved. Percutaneous oxygen saturation was higher than 90%. Echocardiography showed patent superior and inferior vena cava anastomosis without thrombosis, stenosis, atrioventricular valve regurgitation aggravation or pulmonary venous return obstruction. All survival patients were in New York Heart Association class Ⅰ or Ⅱ. None of the patients had arrhythmia, chronic effusion or protein losing enteropathy. ConclusionEarly and mid-term results of modified Fontan procedure were satisfactory for children with complex CHD. For children with high risk factors, staged Fontan procedure can reduce surgical mortality.

  • Risk Factors for Delayed Sternal Closure in Operation for the Neonates with Congenital Heart Disease

    ObjectiveTo analyze the risk factors for delayed sternal closure (DSC) in the operation for the neonates with congenital heart defects. MethodsWe retrospectively analyzed the case notes of the 203 neonates with congenital heart defect in our hospital between January 2010 and June 2014. There were 152 males and 51 females at age of 0-28 (17.68±8.62) days. The relative factors were analyzed by univariate and multivariate logistic regression. ResultsThese factors significantly correlated with DSC in univariate analysis:age at operation, premature, low weight (weight≤2.5 kg) at operation/weight at operation, RACHS-1, mechanical ventilation before operation, continuous use of intravenous cardiovascular drugs before operation, CPB time, aortic clamping time, total circulatory arrest with profound hypothermia. The results of logistic regression analysis showed that weight at operation/low weight, pre-operative mechanical ventilation, total circulatory arrest with profound hypothermia were independent risk factors for DSC. ConclusionWeight at operation/low weight, pre-operative mechanical ventilation, and total circulatory arrest with profound hypothermia are the independent risk factors for DSC in the operation for the neonates with congenital heart defects.

  • CLINICAL STUDY ON ZYGOMATIC SPINDLE-SHAPED OSTEOTOMY AND INTERNAL PUSH OF TITANIUM SCREW ANCHOR IN TREATMENT OF PROMINENT MALAR

    ObjectiveTo explore the effectiveness of the zygomatic spindle-shaped osteotomy and internal push of titanium screw anchor for prominent malar. MethodBetween July 2011 and January 2015, 58 patients with prominent malar underwent zygomatic spindle-shaped osteotomy and internal push of titanium screw anchor. There were 3 males and 55 females, aged 18-33 years (mean, 23 years). They had congenital bilateral prominent malar. Preoperative anteroposterior, lateral, supine position, 45°oblique photographs of the face were taken, three-dimensional CT reconstruction of face was performed. Simple prominent malar was observed in 30 cases, and prominent malar and zygomatic arch in 28 cases; zygomatic bone and zygomatic arch were symmetrical in 51 cases, and asymmetrical in 7 cases. ResultsAll patients obtained stage I incision healing after operation, without infection or hematoma. Numbness of the upper lip occurred in 2 cases, limitation of mouth opening in 1 case, and nasolabial fold deepening in 1 case, which recovered spontaneously after 3 months. Fifty-eight cases were followed up 6-12 months (mean, 10 months). Zygomatic narrow spacing was 10.6-13.9 mm (mean, 11.2 mm). No ptosis of facial soft tissue, zygomatic step, facial nerve injury, raising eyebrow, dysfunction of eyes closure, or temporomandibular joint disorder syndrome occurred. Good bone healing was obtained, zygomatic facial sensation had no obvious abnormality, all patients were satisfied with the improvement of appearance. ConclusionsZygomatic spindle-shaped osteotomy and internal push titanium screw anchor can effectively reduce the cheekbones, and maintain the natural curve of zygomatic body and zygomatic arch. Because of simple operation, less complications, and excellent results, it is an ideal plasty.
