Objective:To evaluate the association between weight gain in late gestation and glycated albumin (GA),visfatin level and neonatal body composition in gestational diabetes mellitus (GDM) patients who are non-obese.Methods:200 pregnant women were enrolled.The preconception body mass index(BMI) of all the research object was less than 25 kg/m2.According to the speed of body mass growth from 28th week of gestation to delivery,the subjects were divided into two groups:excessive weight gain group (n =77) and appropriate weight gain group(n=123).Variance of serum GA,visfatin levels and neonatal birth weight(BW),the percent of body fat in newborn(F％) between two groups were compared,and the relationship between weight gain in late pregnant GDM patients and above values was analyzed.Results:①Serum GA,HbA1 c,visfatin and total cholesterol,triglyceride,low density lipoprotein,very low density lipoprotein levels in excessive weight gain group were higher than those in appropriate weight gain group(P ＜ 0.05).②Mean gestational age,newborn Apgar score immediately,the ratio of baby boys and vaginal delivery rate in two group had no significant difference(P＞0.05).Compared with the appropriate weight gain group,the excessive weight gain group had higher average birth weight and lower blood glucose levels.The proportion of large for gestational ages(LGA) was increased in appropriate weight gain group,and the ratio of abdomen circumference (AC) and head circumference (HC) and the percent of body fat in newborn(F％) were significantly increased in this group(P ＜0.01).③The speed of body mass growth in late pregnancy in GDM patients was positively related with serum GA,visfatin,HbA1c levels and newborn birth weight and the percent of body fat in newborn(r=0.524,0.470,0.456,0.329,0.473,P＜0.001).Conclusions:The monitoring of the serum GA and visfatin levels may have certain clinical value to evaluate the weight gain in late pregnancy of GDM patients.The rapid body mass growth in those patients may accelerate the visceral fat accumulation and worsen existing glucolipid metabolic disorders,and is also closely related to the increase of neonatal BW and F％.

Objective To investigate the effect of antigen retrieval by microwave and the expression of CD 44 s and CD 44v6 in human intracranial metastastic tumor and human glioblastomas, and the relationship between the expression of CD 44 adhesion molecules and the invasion or metastasis of these tumors.Methods After antigen retrieval by microwave-0.1%Triton X-100(MW-T) and buffer solution of microwave-citrate salts(MW-CA), CD 44 s and CD 44v6 were used to detect the expression of CD 44 adhesion molecules in 20 normal human brain tissues, 35 human glioblastomas, and 30 intracranial metastastic tumor by microwave-LSAB immunohistochemical staining technique.Results Integral optical density(IOD) value of CD 44 s and CD 44v6 positive cells restored by MW-T and MW-CA was higher significantly than that of without antigen retrieval (P

Objective To evaluate the therapeutic effect of minimally invasive retractor reduction and fixation through sinus tarsi approach together with external application of Chinese medicine for displaced intra-articular calcaneal fractures. Methods From October of 2009 to June of 2013, 52 patients with displaced intra-articular calcaneal fractures (Sanders type Ⅱ, Ⅲ) were enrolled into the study. The patients received minimally invasive retractor reduction through sinus tarsi approach and fixation with small plate and cannulated screws, and after the operation were given external washing with Chinese herbal formula Shenxing Fang ( mainly composed of Herba Lycopodii, Herba Speranskiae Tuberculatae, Rhizoma Sparganii, Rhizoma Curcumae, Herba Asari, Radix Aconiti Preparata, Radix Aconiti Kusnezoffii Preparat). Follow-up was carried out for the evaluation of the therapeutic effect of displaced intra-articular calcaneal fractures ( Sanders type Ⅱ, Ⅲ). Results Forty cases (involving 44 feet) received the postoperative follow-up for 12-18 months (average being 14.2 months). The Maryland foot scores were 95 points for type Ⅱ displaced intra-articular calcaneal fractures, and 86 points for type Ⅲ fractures. Satisfactory results were achieved in the height, width and length of the calcaneus as well as the B?hler's and Gissane angle ( P<0.01). Conclusion Minimally invasive retracter reduction and fixation through sinus tarsi approach together with external application of Chinese medicine exert satisfying effect for the treatment of displaced intra-articular calcaneal fractures.

Rat models of diabetes were established by injecting streptozocin intraperitoneally.According to random number table,three groups were divided:normal group,diabetic group,and fisetin-treated group.After 24 weeks,all rats were sacrificed.Biochemical parameters of blood and urine samples were tested.The pathological changes were observed by paraffin sections staining with HE.The expression of extracellular matrix proteins was analyzed via PAS and Masson staining.Location of p300 protein expression was analyzed by immunohistochemistry.The protein expressions of p300 and MMP-2 were determined by Western blotting.The mRNA expressions of MMP-2 were analyzed via real-time PCR.The biochemical parameters and kidney pathological images in fisetin-treated group were better than those in diabetic group.The expression of extraeellular matrix proteins was lower than that in diabetic group.Immunohistochemistry analysis showed that among three groups the expression of p300 was mainly in glomeruli,and was also expressed in cell nucleus and cytoplasm and the coloration of fisetin-treated group was weakened as compared with diabetic group.Western blotting analysis showed that the expression of p300 protein in fisetin-treated group was lower than that in diabetic group(P＜O.05).The expressions of MMP-2 mRNA and MMP-2 protein were higher than those in diabetic group (P ＜ 0.05).It is suggested that fisetin may attenuate diabetes associated abnormalities in the kidney of rats,owing probably to inhibiting the expressions of p300 and enhancing the expressions of MMP-2.

Objective To investigate the clinical characteristics and methods of diagnosis and treatment of granular lymphocytic leukemia (LGLL).Methods Clinical data of 3 patients with LGLL were retrospectively analyzed and relevant literature was reviewed.Results 3 patients were all onset with lymphocytosis,whose conditions progressed slowly.The diagnosis of 2 patients was T-LGLL with immunological characteristics of CD3+ CD4 CD8+ CD56-CD57+.The other patient' s diagnosis was NK-LGLL,whose immunological characteristic was CD3-CD4-CD8-CD56+ CD57-.Two of them didn' t need any treatment.One of them was treated with cyclosporine because of agranulocytosis and recurrent infection.Conclusions LGLL is a group of heterogeneous diseases,which clinical characteristic and prognosis are different.Flow cytometric immunopheotype,TCR Vβ analysis and TCR gene rearrangement are helpful to diagnosis.

OBJECTIVETo explore the mechanisms of acupuncture treatment promoting the motor function recovery of neonate rats with cerebral palsy.

METHODSThe improved hypoxic-ischemic encephalopathy (HIE) means was performed to establish the model of neonate rats with cerebral palsy. All neonate rats were randomly divided into 3 groups: sham group, model group and acupuncture group (n = 20). We observed and scored motor function of rats, measured the levels of superoxide dismutase (SOD) and malondialdehyde (MDA) in serum, and also measured the expression of synaptophysin (SYP) and growth associated protein-43 (GAP-43) in the diseased region of cerebral tissue.

RESULTSThe motor function scores (11.3 +/- 0.29) and the serum level of SOD (147.1 +/- 12.7) U/ml in acupuncture treatment group were higher than those of model group ( P < 0.05). The serum level of MDA was lower in acupuncture treatment group than that of model group (P < 0.05). The expression of SYP and GAP-43 in the diseased region of cerebral tissue of acupuncture treatment group were higher than those of model group ( P < 0.05) .

CONCLUSIONAcupuncture-therapy could improve the motor function of neonate rats with cerebral palsy by decreasing the content of MDA in serum, increasing the contents of SOD in serum, and prolonging the upregulation of SYP and GAP-43 expressions in hmin tissue.

The drugs such as sildenafil adulterated in herbal products and dietary supplements may endanger human health. The number of the new modified derivatives is increasing recently. Based on Q-TOF-MS, a new sildenafil analogue was found. It was isolated and purified by preparative liquid chromatography. Its structure was determined by NMR, as 1-[4-propoxy-3-(6, 7-dihydro-1-methyl-7-oxo-3-propyl-1H-pyrazolo[4, 3-d] pyrimidin-5-yl)phenylsulfonyl]-4-methylpiperazine. Compared with sildenafil, the ethoxy group of the benzene ring moiety was moved to the propoxy group, which had not been reported in China. The mass spectrometric behavior pattern of the structure type was summarized, which can greatly accelerate the structural analysis of novel analogues.
