Objective To assess the correlation between the pregnancy‐associated plasma protein A (PAPP‐A)level with gesta‐tional diabetes mellitus(GDM )in primiparous women .Methods The nonparametric test and Logistic regression analysis were used to retrospectively analyze 168 pregnant women of GDM and 273 normal pregnant women ,including age ,body weight ,PAPP‐A ,freeβ‐human chorionic gonadotropin(fβ‐hCG) .Results The age had significant difference between GDM group and control group(P<0 .01) ,the PAPP‐A concentration and corrected multiple of the median (MoM )of PAPP‐A in the GDM group were significantly lower than those in the control group(P<0 .01) .Conclusion Low level of PAPP‐A during early pregnant stage in primiparas is strongly associated with GDM and can be used as the risk factor of GDM .

Objective To investigate the effect of nano-?-linolenic acid on the expression of cathepsin B(CB) in mice with viral myocarditis(VM).Methods Eighty male Balb/c mice were randomly divided into 4 groups:control group,myocarditis group,low-dose intervention group and high-dose intervention group,each group had 20 mice.Mice in control group were inoculated introperitoneally with eagle′s solution,every mouse in the last 3 groups was treated with 0.1 mL Coxsackie B3 virus(CVB3) intraperitoneally.Then,mice in low-dose intervention group and high-dose intervention group were treated with 60 mg?kg-1and 180 mg?kg-1 nano-?-linolenic acid solution for 7 days,respectively.Mice in control group and myocarditis group were treated with 9 g?L-1 saline for 7 days.All mice were killed on the 15th day,and the specimens of hearts and serum were conserved.Myocardial histopathology was determined with hematoxylin and eosin stain.The expression levels of myocardial CB mRNA were detected by reverse transcription polymerase chain reaction.Serum CB concentration was examined by enzyme-linked immunosorbent assay.Results The mortality rate was 0,45%,30% and 20% in control group,myocarditis group,low-dose intervention group and high-dose intervention group,respectively;the mortality rate was significantly lower in high-dose intervention group compared with myocarditis group(P0.05).The expression level of CB mRNA and serum CB concentration were markedly higher in myocarditis group than those in control group(Pa

Objective To provide morphological data for image diagnosis and mediastinal surgery planning.Methods Cross-sectional images of fresh tissues from the first Chinese visible female human data-set were reviewed and the main structures of the superior mediastinum were confirmed on a section-by-section basis.The positional rule of the main structures in various plane of superior mediastinum was found out,and a few key sectional images were selected and compared with the relative images of CT or MRI,and the relative data on the cross-sectional images were collected.Results The cross-sectional images of the first Chinese visible female human fairly displayed the aortic arch and its 3 large branches,superior vena cava,left and right brachiocephalic veins,azygos vein,pulmonary trunk,trachea,esophagus,thoracic duct and so on,as well as their relationship clearly.Conclusion The first Chinese visible female human dataset can almost provide complete and accurate data.

BACKGROUND:Growth differentiation factor 5 (GDF5) has been shown to play a crucial role in the development of chondrocytes via different regulatory mechanisms.
OBJECTIVE:To explore the effect of GDF5 on the chondrogenic differentiation of adipose-derived stem cel s (ADSCs).
METHODS:ADSCs in passage 4 isolated from Japanese White rabbits were cultured in the medium containing 0 (blank control group), 10, 50, 100, 150 and 200μg/L, respectively. The morphological changes were observed, and the optimal concentration of GDF-5 was screened, and its round coverslips at 1, 2 and 3 weeks of culture were selected to undergo immunocytochemistry, toluidine blue staining and immunofluorescent staining.
RESULTS AND CONCLUSION:The growth of ADSCs was stable in the medium containing 10 and 50μg/L GDF5, while apoptotic cel s appeared after induction with 200μg/L GDF5. In the medium containing 100 and 150μg/L GDF5, some spindle-shaped cel s changed into irregular shape, and became round or oval after 7-10 days of culture. The optimal concentration of GDF5 was 100μg/L. The cel s transfected by 100μg/L GDF5 were positive for type II col agen obviously and with blue-stained nucleus. The transfected cel s were positive for toluidine blue, and metachromatic granules were visible in the cytoplasm. The proteoglycan mRNA expression of the transfected cel s was significantly increased, and reached the highest at 3 weeks. These results suggest that GDF5 promotes the chondrocytic differentiation of ADSCs.

A simple, rapid and sensitive colorimetric reverse-transcription loop-mediated isothermal amplification (RT-LAMP) was developed for rapid detection of Middle East respiratory syndrome coronavirus (MERS-CoV). The method employed six primers that recognized sequences of a nucleocapsid gene for amplification of nucleic acids under isothermal conditions at 63 degrees C for 60 min. Products were detected through a LA-320c Loopamp Turbidimeter (real-time RT-LAMP) or visual inspection of color change by pre-addition of Hydroxynaphthol Blue dye (visual RT-LAMP). Specificity of RT-LAMP was validated by detection of several human coronaviruses and common respiratory viruses. MERS-CoV real-time RT-LAMP had a linear correlation (R2) of 0.995 at 10(3)-10(6) copies. The limit of detection of real-time RT-LAMP, visual RT-LAMP and quantitative real-time PCR was 500, 1000 and 100 copies/reaction, respectively. The established RT-LAMP assay was demonstrated to be a rapid screening tool for MERS-CoV infection, and could be suitable in resource-limited clinical sites and for field studies.

Objective To establish the model of Chinese visible liver in order to provide the thin-sectional anatomic base at random direction for hepatic ultrasonography. Methods The sectional images collected from the Chinese visible human liver were used to establish the model of visible liver with the aid of visible software and were compared with the corresponding ultrasonic sections of liver. Results The model of Chinese visible liver was achieved and could be sectioned at random direction. Each section could be displayed distinctly,especially the course and distribution of intrahepatic vessels,and had good corresponding relationship in comparison to those of ultrasonic sections of liver. Conclusion Our model of the visible liver can provide the distinct and integrated sectional anatomic data for hepatic ultrasonography.

OBJECTIVETo observe the efficacy of Shenmai Injection (SI) in preventing and treating adverse reation of chemotherapy on advanced non-small cell lung cancer (NSCLC).

METHODSForty-five patients with NSCLC in III b-IV stage were randomly divided into two groups, the control group treated with chemotherapy alone and the treated group with chemotherapy and SI. The therapeutic efficacy were evaluated after 3 treatment cycles.

RESULTSThere was no significant difference in short-term effect between the two groups (P >0.05), while it showed remarkable difference in Karnofsky scoring and body weight (P < 0.05). The treated group showed a better effect than the control group in reducing adverse reaction, such as decrease of leucocyte and hemoglobin (P < 0.05), while in the aspects of improving thrombocytopenia and the reducing occurrence of nausea/vomitting and alleviating injury of liver and kidney function, it only showed the lower value in the treated group, but with no significant difference as compared with the control group (P >0.05).

CONCLUSIONSI could not raise the efficacy of chemotherapy on NSCLC, but improve the quality of life, raise the body weight of patients and alleviate adverse reaction of chemotherapy as myelosuppression so as to improve the tolerance of organism to chemotherapy.

Objective To study the results of repeat hepatectomy,followed by transcatheter arterial chemoembolization (TACE) and percutaneous microwave coagulation therapy (PMCT),but with or without portal vein chemotherapy (PVC) in patients with recurrence of hepatocelluar carcinoma (HCC) after partial hepatectomy.Methods The data of 33 patients were analyzed retrospectively.All these patients received repeat hepatectomy.They were then divided into two groups:the PVC group (n =19) was treated with PVC + TACE + PMCT,and the non-PVC group (n =14) with TACE + PMCT.Results For the 33 patients,13 (39.4％) developed tumor recurrence ＞2 years from the initial resection while 20 patients (60.6％) developed recurrence within ≤ 2 years.The tumor recurrence consisted of local recurrence in 14 patients (42.4％),and heterochronous recurrence in 19 patients (57.6％).There was a significantly difference in the cumulative survival rates between the two groups (x2 =4.319; P =0.038).The 1y,3y,5y survival rates were 84.2％,42.1％,31.6％ in the PVC Group,and 71.4％,28.6％,14.3％ in the Non-PVC Group respectively.28 sessions of PMCT and 97 sessions of TACE were performed postoperatively (the medians were 1,0.5; 3,3 respectively,the mean ranks were 17.68,16.07; 15.05,19.64 respectively,and the P values were 0.612,0.163 respectively between the two groups).Conclusions For patients with recurrence of HCC after hepatic resection,after repeat hepatectomy PVC + TACE + PMCT gave better survival than those with TACE + PMCT but without PVC.

To compare the curative effects of two surgical treatment methods for open angle glaucoma and cataract patients.
●METHODS: Totally 69 patients with primary open angle glaucoma and cataract were divided into two groups:group A and group B. Thirty- four patients (34 eyes) in group A underwent small incision non -phacoemulsification cataract surgery combined with trabeculectomy, just combined operations, 35 patients (35 eyes) in group B underwent small incision non -phacoemulsification cataract surgery beyond 6mo after trabeculectomy, just two stage operations. Postoperative intraocular pressure at 1wk and 3mo, postoperative corrected visual acuity and filtering bleb at 3mo were observed, and intraoperative and postoperative complications were compared. All the patients were followed up for 3-6mo.
● RESULTS: All the visual acuity were increased compared with that before surgery in two groups, the difference was not statistically significant. All the intraocular pressure was controlled in two groups, the difference was not statistically significant, and the difference about the filtering bleb was neither statistically significant ( P > 0. 05 ). There were no serious intraoperative and postoperative complications in two groups.
● CONCLUSlON: The two stage operations and the combined operations both can control theintraocular pressure and improved visual acuity of open angle glaucoma and cataract. The two stage operations may prevent a second operation for post trabeculectomy cataract, allowing earlier visual rehabilitation.
