The paper described efforts made by Guangdong province to achieve a goal of the healthcare reform Serious diseases can be treated within the county.In this reform,the province attempts such operation mechanisms as autonomous type,guided type and trusted type for the purpose of elevating the service capabilities of county-level public hospitals.To this end,four independent operation mechanisms have also been built for talent development,remuneration incentive,specialty development,and cost control.All these efforts aim at encouraging the hospitals to improve service capability and quality.

ObjectiveTo evaluate the feasibility of detecting the mutations of KRAS,EGFR in nonsmall-cell lung cancer and colorectal cancer patients with high resolution melting curve analysis. MethodsAt first,the mutations in KRAS exon 2 and EGFR exons 18 to 21 of 5 patients with non-small cell lung cancer and 5 patients with colorectal cancer were detected by high resolution melting curve analysis.Then the results were confirmed with direct sequencing. ResultsBy high resolution melting curve analysis,1 of 10 patients was found to carry EGFR 19 mutation who was harboring 2236-2250del mutation.By direct sequencing,consistent results of the patients with mutations orwithout mutations were got. Conclusion s The new high resolution melting curve analysis was more efficient,more convenient than direct sequencing.Moreover,it was a low-cost test,which was suitable for clinic test.

Objective To investigate the clinical effects of bioglue compound and anatomic plate in treatment of tibial plateau fractures. Methods 28 cases of tibial plateau fractures were treated by means of open reduction and internal fixation with bioglue compound and anatomic plate. The intervals between operation and injury ranged from 5 to 10 days. The amounts of bioglue compound implanted ranged from 3 to 8 grams. Results All the patients were followed up for 6 to 22 months. All the fractures healed satisfactorily without sunken joint surface. According to Mechant criteria, the result was excellent in 13 cases, good in 11 cases, moderate in 3 cases and poor in 1 case. The total excellent and good rate was 85.3 %. Conclusion Internal fixation with bioglue compound and anatomic plate can result in good effects in treatment of tibial plateau fractures, because the bioglue compound possesses high bone inductive potentialities to repair bone defects.

Objective To evaluate the effect of isoflurane preconditioning on cell apoptosis during renal ischemia-reperfusion (I/R) in rats.Methods Thirty male Sprague-Dawley rats, aged 12-14 weeks, weighing 300-320 g, were randomly divided into 3 groups (n =10 each) using a random number table: sham operation group (group S);I/R group;isoflurane preconditioning plus I/R group (group Iso+I/R).The rats were anesthetized with intraperitoneal pentobarbital sodium 30 mg/kg.To establish the model of renal I/R injury, the right kidney was removed, and the left renal pedicle was occluded for 30 min with atraumatic mini-clamp for 30 min, followed by 2 h reperfusion.In Iso+I/R group, 1.5% isoflurane was inhaled for 1 h, followed by 30 min of washout before I/R.In S and I/R groups only oxygen 2 L/min was inhaled for 1 h.Arterial blood samples were taken at 2 h of reperfusion to determine the concentrations of serum creatinine (Cr), blood urea nitrogen (BUN) and cystatin C (CysC).The animals were then sacrificed, and left kidneys were sampled for determination of the cell apoptosis (by TUNEL), expression of p53, Bax and Bcl-2 mRNA (using real-time fluorescent quantitative PCR), and expression of Bax, Bcl-2, and caspase-3 (by Western blot analysis).The Bcl-2/Bax ratio was calculated.Results Compared with group S, the serum Cr, BUN, and CysC concentrations were significantly increased, the Bcl-2/Bax ratio was decreased, Bcl-2 mRNA, Bax mRNA, Bcl-2, Bax and caspase-3 expression was up-regulated, and AI was increased in group I/R.Compared with group I/R, the serum Cr, BUN, and CysC concentrations were significantly decreased, the Bcl-2/Bax ratio was increased, Bcl-2 mRNA, Bax mRNA, Bax and caspase-3 expression was down-regulated, and AI was decreased in group Iso+I/R.There was no significant difference in p53 mRNA expression among the three groups.Conclusion Regulating the balance between Bcl-2 and Bax and inhibiting apoptosis in kidney cells are involved in the mechanism by which isoflurane preconditioning reduces renal I/R injury in rats.

Objective To study the effect of early enteral nutrition(EN) and total parenteral nutrition(TPN) in patients with severe acute pancreatitis by a mata analysis.Methods Randomized controlled trials of TPN and early EN in patients with severe acute pancreatitis were searched in Medline,Pubmed and Embase from Jan 1970 to June 2009,and Cochrane Library(Issue 2,2009).Seven studies were enrolled into the analysis.The detail about the trial design,characters of the subjects and results of the studies were reviewed by two independent authors and analysed by using Revman 5.0.18 software.Results Compared with TPN,early EN was associated with a significantly lower incidence of pancreatic infections(OR =0.38,95% CI :0.18~0.82,P =0.01),organ failure(OR =0.43,95% CI :0.23~0.79,P =0.007),fewer surgical interventions(OR =0.34,95% CI :0.18~0.63,P =0.0006) and mortaily(OR =0.41,95% CI :0.19~0.88,P =0.02).However,there was no significant difference in total infections [ OR =0.43,95% CI(0.17,1.10),P =0.08]between patients with TPN and early EN.Conclusions Early EN could be the preferred nutrition feeding method for patients with severe acute pancreatitis.

Objective To investigate the characteristics of dysplasia in myeledysplastic syndrome (MDS). Methods 716 samples of adult patients with abnormal blood routine and unelear cause were collected between July 04, 2003 and March 14, 2007. Based on the gold diagnostic standard of WHO MDS classification, all eases were detected on cytomorphology, cytochemical stain, bone marrow pathological assay,cytogenetics, flow eytometry et al. The cytological study of bone marrow on some abnormal hematopaietie cells has a diagnostic value to determine clonal or non-clonal diseases and assess sensitivity and specificity. Results in the complicated various dysplasia of hematopeiefic ceils, the following characteristics can be the main basis of cytomorphological diagnosis: one of granular Auer bodies, micronuclens (MN), or nuclear budding, erythroid nuclear budding, megakaryocytes presented in peripheral blood, myeloblast or prorubricyte exhibited in peripheral blood, ringed sideroblasts>1%. The subordinate basis of cytomorphological diagnosis development of nuclei, ring-shaped nuclei, and aggregation of nuclear chromafin, erythroid multi-nuclei, odd nucleus, mother-daughter nucleus, nuclear fragmentation, vacuole, anisoeytosis and mieromegakaryocytes.Conclusion Cytomorphologic assay is the base for the diagnosis of MDS, however, it presents certain limit,especially when eytomnrphoiogical change does not possess specificity for early MDS. Hereby, it requires to combine other deteetion methods.
