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 The rational medication route of puerarin was explore d by studying the concentration- time curve and by comparing the histological and organic distribution difference of puerarin administered by intravenous injecti on or gastric gavage in mice, so as to supply a referential data for its rationa l application. Methods The NIH mice were used as experimental subject. The pu erarin concentrations in the plasma, tissue and organs at different time points were determined by HPLC. The PK solutions 2.0 program, a noncompartmental model software, was applied to calculate the pharmacokinetic parameters of puerarin an d to construct its plasma concentration- time curve. Results (1)The pharmacok inetic parameters of puerarin in mice were shown that the T1/2E of puerarin susp ension (0.2 mg? g- 1) by oral administration is 38.061min, CL =991.534 mL? mi n- 1, Cmax =3.6? g? mL- 1, Tmax =30 min, and AUC(0- ∞ ) =201.7? g? min? mL- 1, the bioavailability of puerarin suspension is 3.77 % compared to i.v puerarin injection. (2) Administered by intravenous injection (i.v), the puerari n distributed in the liver, kidney, plasma, spleen, muscle, lung, uterus and tes ticle rapidly, and the concentration of puerarin was the highest in the liver an d kidney and lower in the heart and brain. Distribution of puerarin suspension b y oral administration is similar to puerarin injection by i.v. However, the conc entration of puerarin in the tissues and organs by oral administration was lower than by i.v; the liver/heart, liver/brain, kidney/heart and kidney/brain concen tration ratios of puerarin by gavage administration were lower than those by i.v . Conclusion The bioavailability of puerarin by oral administration was poor, but the histological distribution characteristics of puerarin shows that the tox ic and side effects of puerarin are lesser by oral use than by intravenous injec tion.

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.

The effects of E-cadherin-transfected neural stem cells (NSCs) transplantation for spinal cord injury (SCI) in rats were investigated. Sixty SD rats were randomly divided into model control group, NSCs group, empty plasmid group and E-cadherin overexpression group (n=15 each). The animal SCI model was established by using the modified Allen's method. NSCs were cultured. Rats in NSCs group were subjected to NSCs transplantation. E-cadherin gene eucaryotic expression vector and pcDNA3.1-E-cadherin were respectively transfected into cultured NSCs, serving as empty plasmid group and E-cadherin overexpression group respectively. At 7th day after transplantation, neurological function of all rats was assessed by Tarlov score. After rats were sacrificed in each group, the number of BrdU and Nestin positive cells was counted by immunohistochemistry. Immumofluorescence method was used to detect the expression of neurofilament protein (NF) and glial fibrillary acidic protein (GFAP). As compared with model control group, the Tarlov score and the number of of BrdU and Nestin positive cells, and the expression of NF and GFAP in NSCs group, empty plasmid group, and E-cadherin overexpression group were increased significantly (P<0.05), and those in the E-cadherin overexpression group were increased more significantly than the other transplantation groups (P<0.05). It was suggested that E-cadherin could be conductive to nerve regeneration and repair probably by promoting the proliferation and differentiation of NSCs.

Purpose:To evaluate the effect of oxaliplation (L-OHP)+flurouracil/calcium folinate(5-FU/CF) in combination with concurrent radiotherapy for advanced rectal cancer and to find a more effective way of giving them.Meth- ods:Chemotherapy:L-OHP 130 mg/m~2,iv infusion for 2 hours D_1 combined with calcium folinate 200 mg/m~2 for 2 h ours followed by 5-fluorouracil 300 mg/m~2 for 4h D_1～D_5,repeated every 3 weeks.Radiotherapy:The whole pelvic irradiation DT 50～60Gy/25～30/F(5～6 weeks).Results:30 advanced rectal cancer patients entered the study.One patient reached complete response(CR),15 partial response,13 stable disease,and 1 with progression after treatment,The overall re- sponse rate(CR+PR) was 53.3%,the 1-year survival rate was 70% (21/30).The main adverse acute effects were gas- trointestinitis,anemia,neuro-sensory toxicity and irradiation rectitis,bone marrow suppression was mild.Conclusions: This approach of therapy could improve the therapeutic effect on advanced rectal cancer.
