Objective To investigate the levels of serum acute phase protein in different stages of diabetic nephropathy and their implication. Methods This study included 30 healthy subjects and 100 patients with type 2 diabetes mellitus, diabetic patients were further divided into three subgroups according to their urinary albumin excretion rate (UAER): 39 patients with normal UAER, 30 patients with microalbuminuria and 31 patients with clinical proteinuria. C-reactive protein, ? 1-acid glycoprotein (? 1-AAG), ceruloplasmin (CER) were measured with rate nephelometry method, sialic acid was measured with MTT method. Results (1) Acute phase protein concentrations were significantly higher in patients of type 2 diabetes mellitus than those in normal controls. (2) Acute phase protein concentrations were increased with increment of UAER. (3) Some acute phase proteins (? 1-AAG, CER and SA) were correlated with serum cholesterol and triglyceride independently. Conclusion There is acute phase reaction in type 2 diabetes mellitus and the degree of acute phase reaction is correlated with the degree of diabetic nephropathy.

Objective To observe the clinical effect of budesonide combined with salbutamol in the treatment of children with bronchial asthma,and its influence on oxidative stress and serum interleukin-2 (IL-2),soluble IL-2 receptor (sIL-2r) levels.Methods 70 children with bronchial asthma were divided into observation group and control group according to the different treatment,35 cases in each group.The observation group was inhaled budesonide combined with salbutamol,the control group was given salbutamol inhalation therapy.The clinical efficacy of the two groups was observed,and the changes of serum oxidative stress factor,IL-2 and sIL-2r levels before and after treatment in the two groups were compared.Results In the observation group,20 cases were cured,7 cases were markedly effective,effective in 5 cases,the total effective rate was 94.3％.In the control group,17 cases were cured,6 cases were markedly effective,effective in 4 cases,the total effective rate was 77.1％.The total effective rate between the two groups had statistically significant difference (x2 =26.543,P ＜ 0.05).After treatment,the malondialdehyde (MDA),end products (AOPP) of the observation group were (16.26 ± 1.76)U/L,(42.123 ± 5.745) μmol/L,respectively,which were lower than those of the control group [(22.16 ± 2.84) U/L,(63.63 ± 6.22) μ mol/L,t =23.354,25.348,all P ＜ 0.05].The glutathione peroxidase (GSH-PX),superoxide dismutase (SOD) of the observation group were (236.46 ± 32.25) ng/L,(19.643 ± 3.587) ng/L,respectively,which were higher than those of the control group [(197.43 ± 18.42) ng/L,(18.244 ± 2.446) ng/L,t =18.943,15.123,all P ＜O.05].The IL-2,sIL-2r levels of the observation group were (5.28 ± 2.65) μg/L,(30.376 ± 2.147) mg/L,respectively,which were significantly lower than those of the control group [(9.84 ± 3.22) μg/L,(37.564 ± 1.323)mg/L],the differences were statistically significant (t =21.378,24.643,all P ＜ O.05).Conclusion Inhaled budesonide combined with salbutamol in the treatment of children with bronchial asthma is helpful to control the symptoms of asthma,and can inhibit oxidative stress,reduce serum sIL-2r and IL-2 levels,it is worthy of promotion.

Objective To explore the common pathogen of infantile convulsions associated with mild gastroenteritis, and to study the differences between the seizures caused by the two kinds of virus.Methods RT-PCR was used to detect Rotavirus (RV) and Norwalkvirus (NoV) in stool and cerebrospinal fluid of 30 cases with infantile convulsions associated with mild gastroenteritis. The differences between the frequency of seizures caused by two kinds of virus were analyzed by statistical methods (two-sample t-test).Results 17/30 (56. 7%) were RV-positive in stool and 3/17 (17. 7%) in cerebrospinal fluid; 6/30 (25.0%) were NoV-positive in stool and 1/6 (16. 7%) in cerebrospinal fluid. The seizure frequency with NoV infection was (4. 33 ± 1.75) times, and RV infection patients was (2. 53 ± 1.12) times (P ＜ 0. 01).The seizure frequency of CSF virus-positive children was (4. 75 ± 1.71) times compared to (2. 63 ± 1.21)times in virus-negative children (P ＜ 0.01). Conclusion The common pathogens causing infantile convulsions associated with mild gastroenteritis were RV and NoV. The degree of NoV infection affecting the central nervous system may be greater than RV. The presence of the virus in cerebrospinal fluid may lead to higher incidence of seizures,but their exact roles related to the occurrence of seizures remain to be further studied.

ObjectiveThis study evaluates the feasibility of intensity-modulated radiation therapy (IMRT) to treat patients with 1 -5 brain metastases from non-small cell lung cancer (NSCLC).Methods 30 IMRT patients with brain metastases for NSCLC studied retrospectively.Whole brain radiotherapy plus three-dimensional conformal radiotherapy (WBRT + 3DCRT) and WBRT plus stereotactic radiotherapy ( WBRT + SRT) plans were generated.Planning target volume ( PTV ) and organs at risk dose were measured and compared by dose volume histogram.Differences were analyzed in the three techniques by Wilcoxon Z -test.Results D99％ of the shoulder ( D99％-D90％ ) from IMRT were higher than from WBRT +3DCRT and WBRT+SRT in all cases.From D15％ of slope (D90％-D10％) to D5％ of tail (D10％ -D1％ ),IMRT were lower than WBRT + 3DCRT and WBRT + SRT ( Z =- 4.72,P =0.000 and Z =- 4.72,P =0.000).D10％ and D5％ of IMRT were (35.1 ±1.42) Gy and (37.7 ±2.91) Gy,WBRT +3DCRT were (36.5±2.86) Gy and ( 39.1 ± 3.56) Gy ;WBRT + SRT were (36.2 ± 2.57) Gy and ( 38.7 ± 3.67) Gy.IMRT vs WBRT+ 3DCRT and WBRT + SRT were significant ( Z=-3.18,-3.18,P=0.001,0.001 and Z=- 4.11,- 3.02,P =0.000,0.002) in 13 patients with 3 - 5 brain metastases.The total mean monitor units were 14756.3,9614.8 and 9043.2 for IMRT,WBRT +3DCRT and WBRT + SRT plans,respectively,with a 38.7％ reduction from IMRT to WBRT + SRT (Z =-4.78,-4.78,P =0.000,0.000).The brain doses around metastases were similar in the three techniques with 1 -2 metastases,but IMRT was the best with 3 -5 metastases.ConclusionsIMRT can advance brain metastases dose and improve the planning target minimum dose and spare the dose around brain metastases.Only IMRT is the best choice for just sparing the dose around brain metastases among 3 -5 brain metastases.

Objective To establish the genetic test technique of trisomy 21 concurrently conducts with prenatal diagnosis for hereditary hearing loss. Methods Fifty-four pregnant women who underwent prenatal diagnosis for hearing loss of their fetuses in Chinese People's Liberation Army General Hospital from March 2009 to May 2010 were enrolled in this study. All probands from the deaf families have confirmed the causative mutation for hearing loss in Genetic Testing Center in Chinese People's Liberation Army General Hospital. The mean age of 54 pregnant women is 31 years at pregnancy of 18 - 26 weeks, 5 cases ＞ pregnancy of 23 weeks, 9 cases ≥ 35 years. All subjects did not conduct the serologic tests for trisomy 21before. Fifteen to twenty ml amniotic fluid was drawn from 49 cases at pregnancy of 18 - 23 weeks and 5 cases ＞ pregnancy of 23 weeks. One to two ml umbilical blood was drawn from 5 cases ＞ pregnancy of 23 weeks. For 9 cases ≥ 35 years, amniotic fluid cell culture and karyotyping analysis were conducted concurrently. A multiple quantitative fluorescent ( QF) PCR and six microsatellite markers were applied to as trisomy 21. Results (1) Fifty-four fetuses were successfully conducted prenatal genetic diagnosis for hearing loss (included GJB2 and SLC26A4). Ten fetuses copied the exactly same genotypes as the probands. The other 44 cases fetuses did not copy the same genotypes as the probands and won't develop hearing loss. The hearing test showed normal hearing for the neonates. (2) All the 54 fetuses were excluded of trisomy 21 by QF-PCR and were verified after birth. Five fetuses with advanced maternal age were performed karyotyping analysis and showed normal. The diagnostic results of QF-PCR can be obtained in 1 - 3 days without misdiagnosed. Conclusions QF-PCR is an efficient, rapid and accurate technique for detection of trisomy 21 without increasing sample amount. It can be used for fetuses who were undertaken hearing loss gene test or other prenatal gene test.

Objective To analyze the effectiveness of chronic disease management among suburb residents to secure an optimal health management model. Methods Since 2002, physical examinations had been conducted for rural residents aged≥40. Hypertensive patients detected on health check received medical evaluation and risk factor intervention. Results The incidence of high blood pressure decreased from 26.57% in 2002 to 11.99% in 2007-2008. The mortality of cerebrovascular disease declined from 68.00% to 5.26%. The incidence, disability rate, and death rate of hypertension related-stroke were also significantly reduced. Conclusion Primary healthcare center-based chronic disease screening, along with the health management network, can largely decrease the incidence, disability rate, and mortality of stroke associated with high blood pressure.

Objective To study the expression of gonadotropin releasing hormone receptor (GnRH receptor) in the stomach of Sprague-Dawley rat exposed to light stress. Methods We established illumination stressed models that the rats were exposed to continuous light(totally 64 rats, 32 rats for experiment and control group, respectively). Then,stomachs were taken from the rats when the rats exposed to continuous light for 1 day, 2 days, 3 days, 4 days, 1 week, 2 weeks, 3 weeks, 4 weeks and their control groups, respectively.The localization and the expression of GnRHR and GnRHR mRNA in stomachs mucous membrane were detected using immunohistochemistry, Western blotting and real-time PCR. Results Immunoreactivity was displayed mostly in the parietal cells in gastric gland. There were not differences of this distribution in all groups of constant illumination and their control. The immunoreactive materials were distributed on membrane and in cytoplasm of all positive cells, but not in nuclei. The level of GnRHR in rats exposed to continuous illumination were higher from one week to four weeks compared with that in control(P<0.05), and the level of GnRHR reached the peak when rats were exposed to constant illumination for two weeks (P<0.01). The quantity of GnRH mRNA in rats exposed to continuous illumination were higher from three weeks to four weeks compared with that in control(P<0.05). Conclusion The expression of GnRHR in digestive tract was effected by illumination stress.GnRH might regulate digestive function by interaction with GnRHR, suggesting that GnRH may be acted as a hormone, not only responded to normal physiological function of digestive tract but also responded to stress activity.

Objective To investigate apoptosis of HepG2 ceils after transfecfion with LIGHT gene and interferon-γ. Methods LIGHT gene and interferon-γ were transfected into HepG2 cells by liposome mediated method. The HepG2 cells were divided into group A (transfected with LIGHT gene or interferon-γ), group B (transfeeted with LIGHT gene and interferon-γ) and group C (non-transfection group). The apoptosis rate of the HepG2 cells and the expression of Bcl-2 and Caspase-8 were detected 12, 24, 48 hours after transfeetion. Results (1) The apoptosis rates of HepG2 cells at hour 12, 24 and 48 after transfeetion were 18.8% ± 3.5%, 25.7%± 2.8% and 36.4% ±3.6% in group A, 23.8% ±2.4%, 31.1% ±2.1% and42.5% ±4.5% in group B, and 8.7% ± 2.1%, 9.3% ± 1.6% and 10.9% ± 1.2% in group C. There was a significant difference in apoptosis rate among the 3 groups (F = 15.69, 53.33, 48.28, P < 0.01). (2) The expression of Bcl-2 in HepG2 cells at hour 12, 24 and 48 after transfection was 16.4% ± 5.0%, 13.4% ± 3.5% and 8.6% ± 2.3% in group A, 14.7%±3.8%, 9.1% ±2.0% and 4.6% ±2.0% in group B, and 25.3% ±6. 3%, 19.8% ±4.4% and 10.1% ±3.8% in group C. There was a significant difference in the expression of Bcl-2 among the 3 groups (F = 6.19, 12.29, 5.81, P <0.05). (3) The expression of Caspase-8 at hour 12, 24 and48 after transfection were 19.3% ±2.4%, 27.2% ±1.9% and 33.7% ±3.0% in group A, 22.7% ±2.2%, 30.9% ±3.1% and 38.2% ±3.2% in group B, and 1.2% ±0.8%, 1.8% ±0.6% and 3.2% ±1.5% in group C. There was a significant difference in the expression of Caspase-8 among the 3 groups (F =71.54, 112. 78, I01.61, P < 0.01). Condusions LIGHT gene can signiticanfly promote cell apoptosis through regulating the expression of Bcl-2 and Caspase-8. Interferon-γ enhanced the effect of LIGHT gene on the apoptosis of HepG2 cells.
