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.

Objective:To observe the therapeutic effect and toxicity of local Kanseran injection in combination with chemotherapy in advanced NSCLC patients.Methods:A total of 18 cases was recruited in this study. After desensitization,Kanseran injection was injected into tumor mass through fibrobronchoscope,2 mg every time,once per week. Meanwhile,MVP regimen was administered.Results:Of the 18 patients,1 was completely relieved,7 cases were partially relieved. The response rate was 44.4%. After treatment,when examined by fibrobronchoscope the tumor masses of 15 patients became smaller. The main side effects were fever,alopecia and gastrointestinal reaction,which were mild and tolerable.Conclusion:Local Kanseran injection into tumor mass in conjunction with chemotherapy is effective and safe in the treatment of advanced NSCLC patients with bronchus obstruction.

Objective To explore prognostic factors of renal cell carcinoma and investigate the association of neutrophil-to-lymphocyte ratio (NLR) with the prognosis of renal cell carcinoma (RCC) in patients who received nephrectomy treatment.Methods We retrospectively reviewed the records of 1325 patients with renal cell carcinoma who underwent nephrectomy between January,2008 and December,2012.We retrospectively analyzed the clinicopathologic characteristics of patients.The optimal cutoff value for NLR was determined using receiver operating characteristic curve (ROC) analysis.We defined them as high NLR group when NLR ≥ 2.7 and low NLR group when NLR ＜ 2.7.Overall survival (OS) and recurrence free survival (RFS) were estimated using the Kaplan-Meier method and compared using the logrank test.Multivariate models were used to analyze the association of NLR with clinicopathologic outcomes.Results By the end of the study, 1220 cases were followed up.The follow-up rate was 92.1％.Mean follow-up was 40 months (range 2 months to 87 months).The three-year and five-year overall survival rate were 91.3％ and 86.9％, respectively.Meanwhile the three-year and five-year recurrence free survival rate were 88.2％ and 85.8％ ,respectively.2.7 was selected as the optimal cutoff value to differentiate between low NLR and high NLR.A NLR ≥2.7 was significantly associated with worse 5-year overall survival and worse 5-year recurrence free survival than a NLR ＜2.7,91.4％ vs 87.3％ ,89.6％ vs 71.9％ (P ＜0.05).Age ＞65, presentation mode with symptom, higher tumor stage, higher Fuhrman grade,histologic subtype,neutrophil count ≥ 4.5, lymphocyte count ＜ 1.7, NLR ≥ 2.7 significantly correlated with poor OS on univariate analysis.Multivariate analysis revealed that higher tumor stage, preoperative NLR ≥ 2.7 at diagnosis were poor independent prognostic factors for OS of renal cell carcinoma.Conclusion High NLR was independent poor predictor of renal cell carcinoma.

Purpose To explore the feasibility of optimizing monochromatic images in reducing iodinated contrast dose in CT pulmonary angiography (CTPA). Materials and Methods Sixty-eight patients undergoing CTPA were randomly divided into two groups, with half in research group and half in conventional group to evaluate image quality. Research group underwent spectral CT imaging with the injection of 30 ml Omnipaque (300 mgI/ml) and optimal monochromatic images were postprocessed using the software of GSI viewer. Conventional group underwent conventional CTPA with the injection of 80 ml Ultravist (370 mgI/ml). The CT values were measured respectively in the main pulmonary artery, left pulmonary trunk, right pulmonary trunk, left lobe artery and right lobe artery. The contrast noise ratio (CNR) in two groups were calculated, and image quality were subjectively assessed. Results The total iodine intake in research group (9000 mg) was significantly lower than that of conventional group (29 600 mg). CNR in the main pulmonary artery, left pulmonary trunk, right pulmonary trunk, left lobe artery and right lobe artery in research group was significantly higher than that of conventional group (t=2.07-2.71, P<0.05). Subjective image quality scores in research group were also higher than that of conventional group but had no statistical difference (Z=-0.944, P>0.05), while there was a good agreement between the two readers (Kappa=0.8, P<0.05). Conclusion It is possible to reduce iodinated contrast dose using spectral CT imaging and improve the image quality of CTPA.

Objective To optimize the best subculture cycle through studying the influence of subculture time on tube plantlet growth of Dendrobium huoshanense and the change of medium composition.Methods Height,tiller,fresh weight,and chlorophyll content of the tube plantlet and pH value,water content,and sugar content of the medium were measured after different cycles of the subculture,the cost of culture medium for subculture was calculated as well.Results The height of the tube plantlet increase 282.86%,the tiller increase by 3.5 times,fresh weight reaches its maximum,chlorophyll content of the tube plantlet almost reaches its maximum after 40 d subculture;while water content and sugar content of the medium are decreased to the lowest point,pH value of medium(

Objective To evaluate the imaging features of acute necrotizing encephalopathy caused by children A H1N1 influenza.Methods CT and MRI brain imaging data of three children acute necrotizing encephalopathy caused by A H1N1 influenza virus and proved by clinical and laboratory investigation were analyzed.All the three children got CT and MRI scan because of coma while in hospital.Results All cases represented multifocal damage,and some were symmetrical.Bilateral thalamencephalons were involved in the all cases.Bilateral grey and white matters of frontal lobe,temporal lobe,parietal lobe and occipital lobe,and hippocampi,putamina,external capsule,brain stem,bilateral cerebellum,could be seen multifocal damage,and some were symmetrical.All the cases showed brain swelling in varying degrees.These region presented low density in CT,hypointensity on T1 weighted series and hyperintensity on T2 weighted series and FLAIR series in MRI.Conclusion The imaging features of acute necrotizing encephalopathy caused by children A H1N1 influenza represented multifocal and symmetrical damage and brain swelling.It may be characteristic that bilateral thalamencephaloas were involved.The patient was serious,and fatality rate was high.So we should pay much attention to acute necrotizing encephalopathy caused by children A H1 N1 influenza.

Objective To analyze the clinical effects of low molecular heparin calcium on early onset severe pre-eclampsia.Methods Sixty patients with early onset severe pre-eclampsia at 26-34 weeks of gestational age were divided into treatment group(28 cases)and control group(32 cases).The conventional treatment was delivered in control group and low molecalar heparin calcium(LMWHC)was used in treatment group additionally.The time of prolonged gestational age,umbilical arterial S/D ratio,amniotic fluid index,placenta weight,neonatal weight and Apgar score were measured in two groups.Results The time of prolonged gestational age was 10.19 ±4.57days in treatment group and 6.14 ±3.56 days in control group,which were significantly different(P ＜ 0.01).Umbilical arterial S/D ratio,amniotic fluid index,placenta weight and neonatal weight were all significantly different between the two groups(P ＜ 0.05).Neonatal Apgar score in treatment group was remarkably improved(P ＜ 0.01).Conclusion LMWHC treatment in the patients with early onset severe pre-eclampsia could extend gestational age,increase neonatal weight and improve perinatal outcomes.
