Objective To investigate the role of cyclophilin A (CypA) and CD147 in the process of skin aging. Methods Twenty cases of tissue samples from junior group(＜15 years old), middle age group(30-40 years old)or old age group (＞65 years old) were collected from photophobic and exposal parts of skin, respectively. Immunohistochemistry (IHC) and in situ hybridization (ISH) were carried out to semi-quantitatively detect the expression level of CyPA and CD147. Results IHC demonstrated that both CyPA and CD147 were expressed in both photophobic and exposal parts of normal human skin in all 3 groups. The expression levels of both CyPA and CD147 were increased with increase in age. There were significant differences in both CyPA and CD147 expression among 3 groups (P<0.05). CyPA and CD147 were also positively correlated in all 3 groups. Similar results were achieved by ISH. Conclusion The interaction between CD147 and CyPA might play an important role in the process of skin aging.

Objective To investigate the clinical value of 99Tcm-MIBI gated G-MPI in detecting the myocardial damage in sarcoglycanopathy.Methods 99 Tcm - MIBI G - MPI was performed in 8 patients (3 males,5 females,age ranged from 10 to 30 y) with sarcoglycanopathy confirmed by clinical results and molecular pathology and 4 healthy persons as control group.Quantitative gated SPECT (QGS) software was used for processing and interpretation.Myocardium of left ventricle was divided into 7 segments and 20 subsegments.A five-point scoring system was used to evaluate the myocardial damage.Results Seven patients showed positive results in G-MPI (7/8).Fifty-nine sub-segments of injured myocardium were detected in the 140 sub-segments of 7 abnormal patients.One abnormal segment was observed in 1 patient,two abnormal segments were detected in 2 patients,and ≥3 abnormal segments were observed in 4 patients.Enlarged left ventricles were detected in 5 patients (5/8),and the LVEF of 3 patients among them decreased to (43.1 ±2.8)％.Conclusion 99Tcm-MIBI G-MPI can detect myocardial damage in sarcoglycanopathy as a direct and non-invasive method,and can be used in the early diagnosis and long-term follow-up in sarcoglycanopathy.

Objective To explore the difference in Z-score reference range for aorta measurements, and pulmonary artery(PA)/aortic(AO)valve annular diameter ratio(PA/AO ratio)between normal and aortic stenosis(AS)fetuses and to evaluate the diagnostic value of Z-score of aorta in fetuses with AS. Methods A retrospective cross-sectional study of fetal color Doppler echocardiograms were undertook from 300 singleton normal fetuses with gestational age ranged from 16 to 40 weeks.Standardized fetal echocardiographic measurements included AO valve annular diameter and PA valve annular diameter at end-systole,and PA/AO ratio were obtained.With statistical analysis,best model was established for predicting AO and PA using biparietal diameter (BPD)and femoral length (FL)as independent variables.The correlations between standard deviation (SD)and two independent variables (BPD,FL)were analyzed,and the AO Z-score and PA Z-score of normal fetuses were calculated.One hundred and six singleton fetuses with AS were studied whose gestational age ranged from 1 5 to 40 weeks.The AO Z-score and PA Z-score of AS fetuses obtained by using above regression equation and PA/AO ratio were subsequently calculated.The AO and PA Z-scores and PA/AO ratio between normal fetuses and AS fetuses were compared.And the detection rate of AS according to AO Z-score,PA/AO ratio and AO percentile range were assessed.Results Compared with normal fetuses,the Z-score of AO and the PA/AO ratio in AS fetuses were statistically different (P <0.01).While there was no statistical difference of Z-score of PA between two groups (P >0.05).AO Z-score in 96.2% of AS fetuses were found < -3,PA/AO ratio in 95.3% of AS fetuses were found outside 95% CI.The method using AO Z-score had the highest detection rate of AS,the positive predictive value was up to 89.5%,the negative predictive value was up to 98.6%,the sensitivity,specificity and Youden index were 96.2%,96%,and 0.9223,respectively.PA/AO ratio had good but slightly lower diagnostic accuracy than AO Z-score,while AO percentile range performed poor.Conclusions Fetuses whose AO Z-score are outside ±3 and the PA/AO ratio is greater than 1 .4 at the same time are more likely to suffured from AS.Quantification of AO Z-score has important clinical value in the diagnosis of AS,and is more accurate than the percentile range in quantitative assessment of congenital heart growth and development of the fetal pathology of AS.

OBJECTIVETo verify the pharmacological hypothesis of prescriptions by studying the targeted distribution of major components in stewed rhubarb in the rat model with acute pancreatitis (AP).

METHODNormal SD rats (control group, n = 5) and the AP model induced with intraperitoneal cerulein (model group, n = 5) were taken as the experimental objects. Rats of the two groups were orally administered with stewed rhubarb granules (20 g x kg(-1)). Their heart, liver, spleen, lung, kidney and pancreas were collected two hours after the administration. Such constituents as emodin, chrysophanol, physcion, rhein and aloe-emodin and their concentrations in each tissue homogenate were detected by high performance liquid chromatography-mass-mass.

RESULTAloe-emodin and physcion in stewed rhubarb whose concentrations in liver and kidney of normal rats were higher than that in pancreatic tissues, while the distribution spectrums and concentrations of the remaining components in pancreatic tissues had no significant difference with that of other organs. The concentrations of emodin, aloe-emodin, rhein and chrysophanol in stewed rhubarb in pancreatic tissues of the AP model group were higher than that in other tissues and organs, while their concentrations in pancreatic, renal and splenic tissues were notably higher than that in the normal group.

CONCLUSIONIn the conditions of AP, effective components in stewed rhubarb show a targeted distribution feature in pancreas, which provides experimental basis for the pharmacological hypothesis of prescriptions.

Objective To evaluate the accuracy of renal scintigraphy for the estimation of glomerular filtration rates (dGFR) in patients with diabetic nephropathy as compared to the conventional dual-plasma sample clearance method (pscGFR). Methods Forty-six patients with diabetic nephropathy underwent both dynamic renal scintigraphy and dual-plasma sample measurement after 99Tcm-DTPA injection. Paired student t-test and correlation analysis were performed to compare dGFR and pscGFR (normalized to body surface area,1.73 m-2). Results The mean dGFR was higher than mean pscGFR ((51.08±26.78)ml·min-1vs (44.06±29.43)ml·min-1,t=4.209,P=0.000). The dGFR correlated with pscGFR ( r=0.923,P=0.000) linearly (regression equation:pscGFR=1.015×dGFR-7.773,F=254. 656,P=0.000).Conclusions dGFR correlated well with pscGFR. Although it could not absolutely replace the latter in patients with diabetic nephropathy,dGFR could reasonably evaluate the filtration function for these patients.

OBJECTIVETo observe the efficacy and safety of modified Shengma Biejia Decoction (MSBD) combined with CAG program in treating elderly acute myeloid leukemia (AML) patients with yin deficiency toxin stasis syndrome (YDTSS).

METHODSTotally 46 elderly AML patients were assigned to the treatment group (24 cases; treated with MSBD + CAG) and the control group (22 cases; treated with CAG + placebos of Chinese medicine) according to random digit table. The therapeutic course of CM placebo or MSBD was 21 days. The clinical efficacy and adverse reactions were observed. Meanwhile, physical state (ECOG Score), transfusion dependency, and TCM syndrome score were compared before and after treatment.

RESULTS(1) The complete remission rate was 54% (13/24) and the objective response rate (ORR) was 71% (17/24) in the treatment group, obviously higher than those of the control group [36% (8/22); 54% (13/24)], with statistical difference (P = 0.036, 0.042). When comparing the efficacy based on risk level, the moderate and poor ORR was 71% (10/14) and 67% (6/9) in the treatment group, and 57% (8/14) and 33% (2/6) in the control group, with statistical difference between the two groups (P = 0.048; P = 0.010). (2) Compared with before treatment in the same group, the ECOG score significantly decreased, the average infusion time of red cells and platelets were markedly prolonged in the treatment group after treatment (P < 0.05). ECOG score, the average infusion time of red cells and platelets were significantly better in the treatment group than in the control group after treatment (P < 0.05). (3) Compared with before treatment in the same group, scores of fever, hemorrhage, and bone pain were markedly reduced in the control group (P < 0.05); scores of fever, fatigue, hemorrhage, dry mouth, and bone pain were markedly reduced in the treatment group (P < 0.05). Better effect in relief of fever, fatigue, hemorrhage, dry mouth, and so on was obtained in the treatment group than in the control group (P < 0.05). (4) In aspect of hematotoxicity, the incidence of neutropenia, anemia, thrombocytopenia was obviously lower in the treatment group than in the control group [29.2% (7/24) vs 54.5% (12/22); 16.7% (4/ 24) vs 45.5% (10/22); 33.3% (8/24) vs 63.6% (14/22); P < 0.05]. The incidence of fatigue and anorexia was obviously lower in the treatment group than in the control group [37.5% (9/24) vs 63.6% (14/22), 37.5% (9/24) vs 81.8% (18/22); P < 0.05].

CONCLUSIONMSBD combined with CAG program in treating elderly AML patients with YDTSS, with efficacy enhancing toxicity reducing effect, had distinct advantages in improving physical condition and clinical symptoms, and reducing transfusion dependency.

OBJECTIVETo study the effect of rhubarb in treating patients with systemic inflammation reaction syndrome (SIRS) and its mechanism.

METHODSThe 40 patients with SIRS in the treated group were treated with conventional treatment plus rhubarb powder orally or by nasal feeding, the 38 patients in the control group were treated with conventional treatment alone. Serum tumor necrosis factor-alpha (TNF-alpha) was determined by ELISA during the admission and the 3rd day after admission, C-reactive protein (C-RP), complement 3 and 4 (C3, C4) were also determined by auto-scattering turbidimetric quantitative analysis. The parameters were compared between groups and with normal control group.

RESULTSCure rate in the treated group was significantly higher than that in the control group accompanied with lesser occurrence of multiple organ dysfunction syndrome (MODS) and lower mortality. Serum TNF-alpha, C-RP, C3 and C4 in the SIRS patients were increased during admission, which were significantly higher than normal control, but these parameters would be reduced together with the alleviating of symptoms after treatment, particularly after rhubarb treatment.

CONCLUSIONRhubarb could improve the prognosis of patients with SIRS, its major mechanism is that rhubarb has the antagonizing effect against inflammatory cytokines and complements.

Objective To understand the current situation of iodine deficiency diserders(IDD) in Longyan City and to evaluate the effect of prevention and control measures of IDD in order to provide evidence for formulating prevention and control tactics. Methods During the year of 2006 and 2007, the 30 primary schools were screened by population proportion survey(PPS) from the 7 counties of Longyan City. Forty children aged 8-10 years in each school were randomly selected as a group to examine thyroid, and 7 children in each group were selected to measure the urine iodine and the salt iodine at the same time. The goiter rote, the median urinary iodine, the consumption rate of qualified iodized salt, the iodine salt coverage rate, the rate of qualified iodized salt and the non-iodized rate were detected. Results The goiter rate of children aged 8-10 years old in Longyan City was 0.94%(79/8438). The median urinary iodine was 259.12 μg/L. The consumption rate of qualified iodized salt was 97.86% (1462/1494). The iodine salt coverage rate was 99.46%(1486/1494). The rate of qualified iodized salt was 98.38 (1462/1486), and the non-iodized rate was 0.54% (8/1494). Conclusions All indicators have reached the national standard of eliminating IDD in Longyan City.
