In view of the current conditions and reasons about the reform of medical and health system in China,the paper expounds the feasibility of authorized operation with state-owned assets of public hospital and the concrete operational pattern from the angle of hospital operational mechanism, which proposes a new idea about how to effectively solve the contradiction between the limited investment on state-owned health resources and the growing demands on medical health.

Toxoplasma gondii is an intracellular protozoan parasite that infects all warm?blooded animals. The surface anti?gens of T. gondii with the potential for application as antigens of diagnosis and vaccines have been studied extensively in recent years especially for P43 P35 P30 P23 and P22. The studies on the surface antigen in tachyzoites of T. gondii are reviewed in this paper.

AIM: To explore the changes in serum TGF ? 1 in type 2 diabetes mellitus. METHODS: Forty-five cases type 2 diabetes mellitus patients were divided into three groups according to urine albumim excretion rate(UAER): normoalbuminuria(NA)group and microalbuminuria(MA) group and macroalbuminuria group (Overt DN). Serum TGF ? 1, fasting blood glucose(FBG), HbA 1c ,BUN,Cr,Ccr,lipidemia were detected in all cases. RESULTS: Serum TGF ? 1 in NA, MA and ODN groups [(35.02?6.70) ?g/L, (39.31?5.35) ?g/L, (58.58?9.56) ?g/L, respectively] was higher than that in control [(23.95?8.01) ?g/L, P

Objective To explore the effects of different vitamin A(VA) levels on thyroid cells apoptosis and its gene expression of mice taking excessive iodine. Methods Kunming mice were randomly divided into 6 groups according to body weight 3 weeks after born: normal control(NI) group, high iodine(HI) group, low vitamin (LVA) group, high iodine plus low vitamin A(HI+LVA) group, high iodine plus vitamin A1 (HI+VA1) group, high iodine plus vitamin A2(HI+VA2) group. The VA was given in food(4000,4000,0,0,8000,16 000 U/kg), and the iodine was given as potassium iodate in water (I-:50,3000,50,3000,3000,3000 μg/L). The apoptosis was tested using in situ end labehng(TUNEL) method. Reverse transcription polymerase chain reaction (RT-PCR) were used to measure the level of mRNA of apoptosis gene(Fas, FasL, Bcl-2) in tissues. Results Apoptotic index measured by TUNEL method was rising along with the mice age. Compared to NI group[(14.09±5.68)%], apoptotic index was significantly increased in HI[(20.91±9.57)%], HI+LVA[(20.29±9.90)%]and HI+VA2 [(19.51±8.25)%]groups in the three months(P < 0.05). Compared to NI group[(16.80±9.90)%], apoptotic index was significantly increased(P < 0.05) in HI[(23.22±8.58)%],LVA[(22.56±6.17)%],HI+LVA [(25.99±9.62)%],HI+VA1 [(21.65±7.74)%]groups in the six months. Compared with the NI group(Fas: 1.29±0.25,1.27±0.26; FasL: 1.60±0.13,1.65±0.13), the mRNA levels of Fas and FasL in HI group(Fas: 1.57±0.36,1.49±0.35; FasL: 1.85±0.46,1.84±0.32) were increased, but the differences were not remarkable(P > 0.05) in the three and six months. Compared with the HI group, the mRNA levels of Fas in HI+ VA1, HI+VA2(1.33±0.35, 1.30±0.26) groups were decreased to the level in NI group in the six months. The mRNA levels of Fas and FasL were not different (P > 0.05) between HI+LVA(I.60±0.27,1.88±0.46) and HI groups in the three months. The mRNA levels of Bcl-2 were not remarkably differences in the three months (1.05±0.19,0.96±0.33,0.95±0.26,1.18±0.27,1.10±0.19,0.98±0.36, all P > 0.05), and in the six months (1.35±0.28,1.60±0.25,1.48±0.18,1.71±0.26,1.66±0.29,1.56±0.35, all P > 0.05). Conclusions Excessive iodine can cause thyroid cells apoptosis in mice. Supplementation of suitable amount of VA can regulate the levels of the apoptosis-related genes expression, and partly antagonize the apoptosis caused by high iodine.

Objective To comparatively analyze Toxoplasma gondii separated from HIV-positive people and RH strain GRA6 gene. Methods By using the nested PCR the amplification of Dali HIV-positive blood samples and RH strains of Toxo-plasma GRA6 genome was performed. The GRA6 gene amplification positive product was selected and the electrophoresis imag-ing was performed by being digested with the Mse I endonuclease and the gene sequences were measured and analyzed. Re-sults The GRA6 gene fragment 800 bp was successfully amplified and about 600 bp and 200 bp bands were got by Mse I. The sequencing results showed that T. gondii GRA6 gene positive samples had 2 nucleotide variation compared with T. gondii strain RH namely 447 base pair at C becoming G and 623 base pair at G becoming T. At 146 bp and 690 bp the Mse I restric-tion sites TTAA were found. Conclusion The preliminary judgment shows that the Dali HIV-positive T. gondii genotype is consistent with RH strain belonging to genotype I.

Objective To explore the influence of early rapidly increased amino acid dosaging on the nitrogen balance and growth in preterm infants.Methods A total of 37 prematures admitted to our NICU within 24 hours after birth and with birth weight of 1 000 g to 1 800 g from November 2011 to January 2013 were randomly divided into study group (n =18) and control group (n =19).Parenteral nutrition (PE) was provided in both groups within 24 hours after birth.The starting amino acid dose was 1.5g/kg per day,then rose by 1 g/kg per day in study group and by 0.5 g/kg per day in control group,until to maximum of 3.5 g/kg per day.The dosage of lipids,glucose,and electrolytes in parenteral nutrition was provided routinely.The trial was double-blinded.Results In the first 5 days of PE,the nitrogen balance had no significant difference between these two groups (F =0.025,P =0.652) ; however,the time of regaining birth weight was significantly shorter in study group [(7.23±2.48) d] than in control group [(9.42±2.03) d] (t=-2.090,P=0.044).There were no differences between these two groups in trems of completely feeding time,weight gain rate,head circumference growth rate,length of hospital stay,and hospital costs (all P ＞ 0.05).Meanwhile,the rates of neonatal necrotizing enterocolitis,sepsis,mechanical ventilation administration,and damage of hepatic and renal function were also not significantly different.The administration of different dosages of amino acids did not affect the energy intake in both groups (F =1.893,P =0.218).Conclusions Prematures need early amino acid administration,with a starting dosage of more than 1.5 g/(kg · d).Rapid increase of amino acid dosing will not affect early nitrogen balance in premature infants; meanwhile,it contributes to weight gain without increasing the complications and hospitalization costs.
