Delicacy management proves a pressing need in cost management of medical service items in the current hospital operation.This paper first covered the methodology and system of hospital costing.It went on to describe the costing for four major medical service items in a quarter in 2011 using the activity-based costing method with the ultrasonographic section of a large hospital as an example.The outcomes were compared to the traditional costing method and the statutory pricing standards,resulting in the proposal and recommendation on reforming the costing methodology of service item pricing,and applying the activity-based costing management of medical service items in the hospital.

Objective To explore the relationship between methylenetetrahydrofolate reductase (MTHFR) 677C ＞ T and unexplained recurrent pregnancy loss (URPL).Methods All patients were recruited from the outpatient department of Obstetrics/Gynaecology & Genetics of Hangzhou First People's Hospital from January 2013 to May 2014.A case-control study was performed.According to the stochastic indicator method,there were 125 subjects with a history of ≥2 times URPL as the case group,and 905 healthy parous women with no history of URPL as the control group.Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to detect the distributions of the polymorphisms of MTHFR 677C ＞ T,and the results were validated using oligo-chip and direct sequencing.Results The allele and genotype frequencies of MTHFR were 60.0％ for C,40.0％ for T,32.0％ for CC,56.0％ for CT,and 12.0％ for TT in the case group and 67.4％ for C,32.6％ for T,41.4％ for CC,52.0％ for CT,and 6.6％ for TT in the control group,respectively.The prevalence of allele T was significantly higher in the case group than in the control group (OR =1.379,95％ CI =1.051-1.808,P =0.020),the frequency of genotype TT was also significantly higher in the case group than in the control group (OR =2.344,95％ CI =1.220-4.503,P =0.009).Conclusion The fertile women with MTHFR 677T allele and 677TT genotype may be susceptibility to URPL in a Chinese Han population from the Hangzhou area.

Obejective To study the effect of daidzein(Daid) on the enzymes of bone metabolism and bone rebuilding in ovariectomized rats.Method Sixty 3-mon female SD rats were divided into 6 groups:Sham,OVX,OVX-D1～D4 groups.Every day the rats in Sham and OVX groups were given distilled water,and the rats in OVX-D1,OVX-D2,OVX-D3,OVX-D4 groups were given 25,50,75,100 mg/kg bw Daid respectively.After 6 mon,all of rats were killed,and the blood,liver and femur were collected.The content of calcium and phosphorus in serum and the enzymes of bone metabolism were measured.Results The content of calcium,phosphorus and ATPase in serum was increased,but the activity of serum alkaline phosphatase(ALP) and tartrate-resistant acid phosphatase(TRAP-5b) was decreased dose-dependently in OVX-D groups compared with OVX group.Conclusion The expression of bone metabolism-associated enzymes could be inhibited,which resulted in inhibition of bone formation and absorbsion in ovariectomized rats.The new balance between bone formation and absorption could be rebuilt by Daid,through the mechanism of decreasing rate of bone conversion.

Objective Traditional nasolacrimal duct stenting possesses some shortcoming including difficulty of pulling ball head guide wire from the nasal cavity with turbinate hypertrophy and nasal septal deviation. The new method of nose-oral tube track establishment can overcome the forementioned and increase the successful rate. Methods 5 F catheter and arterial sheath were modified to be nasolacrimal duct stent delivery device respectively. Antegrade dacryocystography was taken firstly to display the obstructed site and followed by the modified protocol of inserting the guide wire through nasolacrimal duct and nasal cavity, and establishing the stent delivery track for retrograde stent placement. Results 5 epiphora patients with failure implantation by traditional method were all succeeded through the modified stenting(100%). During 6-mouth follow-up, no serious complications and reocclusion occurred. Conclusion The establishment of eye-nose-mouth-nose of external nasal guide wire track can improve the successful rate of nasolacrimal duct stenting.

Objective:To investigate the neuropsychological characteristics of Chinese agraphia caused by basal ganglia(BG)infarction.Methods:The writing abilities of 40 patients with BG infarction were detected by Chinese agraphia battery(CAB),and all the writing scores and agraphia quotient were calculated.The head CT/MRI images in agraphia and non-agraphia groups were standardized,the infarction were revealed and the superposition of two-dimensional arrays were performed,so that the central tendency of infarction was visually displayed.Results: Among the 40 patients,21 had left BG infraction,and 17 had agraphia;19 had right BG infraction,and 4 had agraphia.The two-dimensional superimposing neuroimages showed that BG infarctions caused agraphia was mostly in the left BG,including the left putamen,the head and body of the caudate nucleus,but there were fewer infarctions in the right putamen and the body of the candate nucleus.BG infarction caused agraphia was mostly aphasic agraphia,which was characterized by the orthographic disorders,paragraphia,and grammar mistakes.Conclusions: BG infarction may result in aphasic agraphia,which suggested that BG is involed in writing and processing,and it is the subcortical center of this advanced neurofunction in writing.

The antagonism of two strains B1 and B2 of Bacillus spp. against pea root rot pathogen Fusarium oxysporum f. sp. pisi was studied. The result of pairing culture showed that B1 and B2 strains of Bacillus spp. had strong antifungal activity to the pathogen. The colonial color of the pathogen changed from gray to white, aerial hyphas increased and entangled into group after treatment with the cell-free fermentational filtrate of B1 or B2. Observation under optical microscope showed that hyphas and spores of the pathogen swelled and distorted with concentrated cytoplasm after treatment, the spores could not germinate or germinated abnormally . A lot of vesicles appeared at the top of the hyphas, and the hyphas stopped growing and broke finally, their cytoplasm spilled from the cell. The cell-free fermentational filtrate of B1 or B2 strains contained 1795.53?g/mL and 1345.93?g/mL protein respectively, from which two antifungal proteins of 103.5 kD (B1 ) and 127.6 kD (B2) were purified.

Objective To investigate the existence of the erythropoiesis inhibitors(?).Methods Twelve patients suffered from uremia with anemia were studied[5 males,and 7 females,(50?12)years].Methylcellulose culture technique was used to culture mice bone marrow cells.The sera from the uremia patients were added to CFU- E and BFU-E culture medium with final concentrations of 1,25%,2.5% and 5%,Mice bone marrow cells were ob- tained from the female Balb/c mice.In vitro CFU-E and BFU-E culture in the presence of sera from uremia patients was compared with that in the presence of normal human subjects with the use of normal mice bone marrows.Re- suits The effects of the sera from uremia patients on CFU-E and BFU-E colon growth were in a dose-dependent manner.The effect was correlated with the concentrations of the sera(P

Objective:To investigate the relationship between gene polymorphisms of disease-relevant multiple cytokines including TNF-α,IL-6,IL-10,TGF-β1,IFN-γand acute graft versus host disease(aGVHD) in allogeneic hematopoietic stem cell trans-plantation ( allo-HSCT ) . Methods:32 cases of recipients received allo-HSCT and 36 cases of normal groups in January 2014 to December 2015 were selected as objects of study. We detected genotypes on specific SNP of target genes by polymerase chain reation ( PCR) combined with gene sequencing and observed the occurrence of aGVHD in postoperative recipients. The influence of cytokine gene polymorphisms on prognosis of allo-HSCT patients was analyzed,and the potential relationship between specific SNP mutation of the disease-relevant cytokine genes and severity of aGVHD was discussed. Results:Distribution of cytokines gene polymorphism including TNF-α-308(G/A),IL-6-174(G/C),IL-10-1082(A/G),TGF-β1+915(G/C),IFN-γ(T/A) had no significant differences with incidence of severe aGVHD(P>0. 05). However,the occurrence of severe aGVHD in allo-HSCT recipients with C/T genotype was significantly higher than C/C and T/T in SNP of TGF-β1+869(P<0. 01). Conclusion:Gene polymorphism of TGF-β1+869(C/T) in allo-HSCT patients was closely related to the occurrence of severe aGVHD. The research show allo-HSCT patients with C/T genotype occurred severe aGVHD more frequently, which is an important potential risk factor to induce the incidence of severe aGVHD. Therefore,detecting gene polymorphism of TGF-β1+869 ( C/T ) in allo-HSCT recipients and developing the appropriate therapeutic regimen may be helpful to reduce the incidence of aGVHD.

Objective To study the EEG discharge index, intelligence test and event-related potential P300 in BECT, and to analyze the change of EEG discharge index and cognitive function before and after the treatment.Methods Sixty patients with BECT were enrolled in this study, they were treated with EEG, intelligence tests and P300 before and after the treatment.Results (1) The EEG discharge index were reduced remarkly after treatment in BECT with levetiracetam and lamotrigine, the difference was statistically significant (P ＜ 0.05).(2) Comparing before and after 3 or 6 months treatment, the latency of P300 had reduced with significant difference (P ＜ 0.05).(3) After 3 months treatment, VIQ and FIQ has no obvious improvement, but PIQ has improved.After 6 months treatment, VIQ、 PIQ and FIQ were improved.The difference was statistically significant (P ＜ 0.05).(4) There was a negative correlation of EEG P300 latency (r =0.175), as well as there was a negative correlation between EEG discharge index and intelligence test (r =0.044).Conclusion There is impaired cognitive function in BECT, especially the more frequently the EEG discharge, the more extended of P300 latency, as well as the more serious damage of intelligence and cognition after treatment.The intelligence were improved after treatment with Levetiracetam and lamotrigine, the longer the treatment time, the more obvious of intelligence levels improve.
