Objective To explore effect of probiotics on improving the feeding intolerance in very low birth weight infants(VLBWI). Methods Sixty cases of VLBWI were randomly divided into two groups, 30 infants as therapy group,another 30 infants as control group.All infants in two groups were given aggressive intravenous nutrition and enteral feeding with preterm formulars. At the same time, probiotics were administered combined with preterm formulars to infants in therapy group. Milk amount, gastric residual, initial time of enteral feeding, time required for full enteral feeding and body weight on day 21 after birth were all recorded.Results Rate of no gastric residual increased significantly in therapy group compared with that of control group(t=6.24 P

· AlM: To investigate the correlation of retinal vein occlusion ( RVO ) with blood lipids and carotid artery changes.
· METHODS: Forty cases ( 40 eyes ) with RVO who presented to Eye Hospital of Xinxiang Medical University between May 2013 and April 2014 were selected as the research objects. Proceeded blood lipids and color doppler ultrasonography examination, including total cholesterol ( TC ) , triglycerides ( TG ) , high -density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol ( LDL-C ) , common carotid artery intima-media thickness, carotid plaques, internal carotid artery blood flow mechanics parameters were detected.Thirty eyes ( 30 cases ) were enrolled as control underwent above examinations.
·RESULTS:TC, TG, LDL-C of RVO group was obviously higher than those of the control group ( P<0.05), while HDL-C level was obviously lower than that of the control group ( P<0.05 ). lncidence of carotid artery plaque formation in RVO group was obviously higher than that in the control group. lntima-media thickness ( lMT ) of common carotid artery was obviously increased in RVO group (P<0.05).Both peak systolic velocity ( PSV) and end diastolic velocity ( EDV ) of internal carotid artery reduced (P<0.05), and Resistance index (Rl) increased (P<0.05).The eyes of the sick side and the contralateral carotid artery measured value had no statistical difference ( P >0.05 ) . There were also no statistical difference between ipsilateral and contralateral carotid artery measured value of control group (P>0.05).There were no differences in age, sex between RVO group and control group (P>0.05).
· CONCLUSlON: Lipid metabolism disorder, carotid artery changes is closely related to the pathogenesis of RVO.

Purpose To investigate the value of MRI T2 mapping imaging in diagnosis of lumbar intervertebral disc degenerative (IVDD).Materials and Methods A prospective study was performed on 100 patients who underwent 1.5T MRI examination because of lumbar and back pain from October 2013 to December 2015 at the Fifth People's Hospital of Shanghai,Fudan University.The MRI examinations included conventional sagittal T1WI and T2WI,axial T2WI and median sagittal T2 mapping imaging.According to Pfirrmann standard,475 lumbar intervertebral discs were graded.T2 values of nucleus pulposus (NP) and annulus fibrosus (AF) of anteriority and posterior with different grades were measured and compared.The correlations between T2 value,age and grade were further analyzed.30 patients were selected and underwent a second MR examination after half a year,and the difference of T2 values between the two MR examinations were compared.Results Except for grade Ⅳ and grade Ⅴ,the differences of T2 values of NP between the other grades of lumbar intervertebral discs were statistically significant (P＜0.05).T2 values of NP were negatively correlated with the grades (r=-0.77).There were no significant differences in T2 values of NP and AF of anteriority and posterior in 30 patients with back pain between the two MR measurements of half year interval (P＞0.05).Conclusion T2 mapping imaging can quantitatively assess the degree of IVDD,especially T2 values of NP can reflect the differences of IVDD with grade Ⅰ-Ⅳ,so it can provide the imaging evidence for the diagnosis of IVDD.

To improve the antibiotics production of Streptomyces qinlingensis sp. nov.,protoplast regeneration combined with physical and chemical mutagenesis was used to selected high-yielding strains. The results showed that the antibacterial activities of strain R-72 from protoplast regeneration and NTG-1,H30-7 from protoplast mutagenesis against Bacillus subtilis were more than 20% higher than that of the original strain,and the heredity characters of those strains were stable in successive ten generations. The further bioassay experiments exhibited that the fungicidal and antibacterial activities of the fermentation broth from R-72,NTG-1 and H30-7 were remarkable increased comparing with that of the starting strain.

OBJECTIVETo investigate the release model of insoluble drug carbamazepine (CBM) based on HPMC matrix tablets.

METHODSCBM release profile from matrices and HPMC erosion rate were determined.

RESULTThe mathematical model by matrix erosion rate and drug release from HPMC K15M were established for the fractional HPMC and CBM released as M(P(t))/M(P(infinity))=-[0.8095ln((t))+1.2775]Meq((-0.0622t-0.305)) and M(d(t))/M(d(infinity))=-[0.1891t-0.1294]Meq(-0.9326). In comparison with the data of HPMC K4M matrix erosion and CBM release from HPMC K4M matrices, theoretical value agreed well with experimental data.

CONCLUSIONThe two mathematical models can be satisfactorily applied to insoluble drug release, which is governed by matrix erosion.

OBJECTIVETo study (CAG) n polymorphism of the androgen receptor (AR) gene in responders and non-responders of male volunteers who received testosterone undecanoate intramuscular injection for contraception and to explore the effect of the polymorphism on hormonal male contraception.

METHODSTwenty-nine non-responders and 34 responders were enrolled in this study as a test and a control group respectively. The numbers of CAG sequence repeats were determined by PCR and DNA sequencing, and the effect of (CAG) n polymorphism on hormonal male contraception was analyzed.

RESULTSThe means of CAG repeats of the test and the control group were 23.62 and 22.97, with no significant difference in between (P > 0.05). The short CAG repeats (n < or = 22) constituted 51.7% in the test group and 50% in the control, while the long ones (n > 22) accounted for 48.3% and 50% , respectively. The short and the long group had a similar distribution. No association was found between CAG repeats and sperm concentration. With FSH > 0.2 IU/L, the probability of azoospermia in the long CAG repeat group was 1.5 times that of the short one.

CONCLUSIONCAG repeats in the AR gene presented polymorphism in the subjects, with no significant difference between the responders and non-responders. Further investigation has yet to be performed into the relationship of hormonal male contraception with CAG repeats or other factors.

The loquat is widely cultivated in China, its succulent fruits, leaves and flower are used as a traditional medicine for the treatment of many diseases. The study is aimed to analyse the content of the four triterpene compounds ( ursolic acid, corosolic acid, maslinic acid, oleanolic acid) in different organs, and investigate the dynamic changes in different phenological period. The triterpenic acids content in the samples was measured by HPLC based on the plant phenological observations. The results showed that order of four triterpenic acids content in different organs from high to low was defoliation (23.2 mg x g(-1)) > mature leaves (21.7 mg x g(-1)) > young leaves (17.5 mg x g(-1)) > fruits (7.36 mg x g(-1)) > flowers (6.40 mg x g(-1)). The triterpenic acids were not detected in the seeds. The total amount of the four triterpenic acids in the loquat leaves collected in the different phenological stages of sprout, flower bud, blossom and fruit varied between 17.8 and 26.2 mg x g(-1) (defoliation), 16.5 and 23.5 mg x g(-1) (mature leaves), 14.7 and 21.5 mg x g(-1) (young leaves), respectively. The content increased progressively with the leaf development, maturation and aging. There was a higher level of the dry material and triterpenic acids accumulation in the mature leaves during fruit enlargement. This paper attempts to present the case for medicinal plants of a broad geographical distribution to study on the secondary metabolites and harvesting time.

OBJECTIVETo investigate clinicopathologic features of solitary plasmacytoma of bone (SPB) and the role of immuno-phenotype and immunoglobulin gene rearrangement detection in the diagnosis and differential diagnosis of SPB.

METHODSA total of 21 cases of SPB were selected during a period from 1990 to 2008. A retrospective clinicopathologic study and immunohistochemistry (EnVision or EliVision methods) of 17 antigens were performed. In addition, universal IgH (FR3A/LJH/VLJH) primers and BIOMED-2 PCR multiplex tubes were used for IgK and IgL rearrangement analysis.

RESULTSThe age of patients ranged from 36 to 72 years with a media of 50 years. Axial skeleton was the most common site of involvement, accounting for 66.7% of the cases (14 of 21), followed by the extremities of 33.3% (7 cases). Low serum level of M-components was found in 5 cases, including two of IgG type (21.4 g/L) and three of IgA type. Clinical manifestations were closely related to the anatomic sites involved, such as pain due to bone destruction, symptoms and signs caused by compression of spinal cord or nerve root, and pathological fracture. All cases presented as a solitary osteolytic lesion. According to the histological grading criteria, grade I tumor was seen in 12 of 21 cases (57.1%). The remaining were grade II (5 cases, 23.8%) and grade III (4 cases, 19.0%). Immunohistochemically, the neoplastic cells expressed two or more plasma cell antigens, including CD138, CD38 and PC, but no CD19 and CD20. CD79a expression detected in 23.8%(5/21) of the cases. Expression of CD56, CD27 and CD44v6 were 57.1% (12/21), 15.0% (3/20) and 23.8% (5/21), respectively. Follow-up data were available in 12 of the 21 patients (57.1%). Five patients were alive and 7 died. Three patients developed multiple myeloma (MM) and died of the tumor.

CONCLUSIONSSPB is a rare tumor with bone pain as the most common presenting symptom due to bone destruction. The diagnosis of EMP can only be established after exclusion of an extramedullay invasion by MM. Immunophenotype and IgH gene rearrangement analysis play important roles in the diagnosis of SPB.
