Objective To study the clinical effect of low molecular weight heparin on fetal growth restriction (FGR) prevention in early pregnancy.Methods 100 pregnant women had been employed in our study,they were divided into two groups,observation( n =60) and control( n =40) group.Both groups were given the natural vitamin E 0.1g,and folie acid 0.4mg daily oral administration,continuing to 12 weeks of gestation.5000 u of subcutaneous dalteparin sodium was added to pregnant women with notmal level of D-dimer in the observation group until 12 weeks of pregnancy,while the dose of Fragmin was adjusted in pregnant women with abnormal level of D-dimer until retuned to normal level.The pregnacy outcome of two groups were compared.Results The gestational age,birth weight,placental weight of the obseruation group was signiticantly higher than thal of the control group ( t =4.55,2.79,11.91,all P ＜ 0.05 ),while FGR,oligohydramnies,fetal distress and the incidence of hypertensive disorters of the obseruation group were significantly lower than that of control group ( x2 =6.50,20.55,7.87,3.76,all P ＜ 0.05 ) ; Compared to the control group,the observation group didn't have higher incidence of intrauterine fetal death,neonatal asphyxia and perinatal death ( P ＞ 0.05).Conclusion Low molecular weight heparin using in early pregnancy was effective in preventing FGR in pregnant women with FGR risk factors.

Objective To analyze the clinical effect of nutritional support for postoperative patients with esophageal cancer with fat emulsion and amino acids (17) and glucose (11%) injection (Calvin injection). Methods A total of 68 patients with esophageal cancer treated in the chest surgery in our hospital from December 2014 to December 2016 were selected and randomly divided into two groups with 34 cases in each group. All patients were treated with surgery for esophageal cancer. The patients in the study group were treated with Calvin injection after operation while patients in the control group were treated with conventional fluid replacement therapy. Subjective comprehensive assessment (SGA) was used to assess the nutritional status of the patients and the weight, serum total protein (TSP), serum albumin (Alb), transferrin (TF) content, urea nitrogen content in on one week, malnutrition improvement and complications of the patients in two groups were recorded and compared. Results The weight of the patients with esophageal cancer in the two groups after operation was decreased, and the weight loss of the patients in the study group was lower than that of the control group and the difference was statistically significant (P<0.01). The decrease degree of TSP, Alb and TF in the study group was lower than that in the control group, and the difference was statistically significant (P<0.05). The negative nitrogen balance of the two groups was improved, and the improvement of the negative nitrogen balance in the study group was better than that in the control group, and the difference was statistically significant (P<0.01). The postoperative malnutrition in the patients with esophageal cancer was improved. The improvement degree of malnutrition in the study group was better than that in the control group, and the difference was statistically significant (P<0.05). The incidence of complications in the study group was lower than that in the control group, and the difference was statistically significant (P<0.05). Conclusion Compared with the traditional method of postoperative fluid replacement, Calvin injection can improve the recovery of the body function of the patients with esophageal cancer after operation, improve the patient's negative nitrogen balance and nutritional status, reduce the incidence of complications, and improve the clinical prognosis. This treatment is safer and more effective and it is worth popularizing in clinical practice.

An HPLC-DAD-MS/MS method was developed for rapid analysis and identification of degradation products of buagafuran. Buagafuran and degradation products were separated on a Zorbax C8 column (5 microm, 4.6 mm x 150 mm) using acetonitrile-water (78 : 22) as mobile phase. The elutes were detected with diode array detector and tandem mass spectrometer via electrospray ionization source in positive ion mode. According to analysis of the retention time, UV spectra and MS, MS/MS data, combined with the possible degradation reaction of buagafuran, the structures of main degradation products were inferred. The results showed that six main degradation products were oxidation or peroxidation productions of buagafuran. Degradation product A was a double bond epoxidation product of buagafuran, degradation products B, C, D and E were the further oxidation products of degradation product A, degradation product F was a peroxidation product of buagafuran. The results indicated that the established method was effective in the rapid identification of the degradation products of buagafuran.

Methods The plasma levels of von Willebrand factor: antigen (vWF: Ag), thrombomodulin (TM), prothrombin fragment 1+2 (F 1+2 ) and P selectin were measured by ELISA in 65 patients with type 2 diabetes (including 33 patients with vascular complication) and 38 healthy people. Results The plasma level of vWF:Ag, TM, F 1+2 and P selectin in group of type 2 diabetes were significantly higher than that of normal controls ( P

A total of 58 patients with simple septic shock were recruited from intensive care unit and divided into control group (n =28) and treatment group (n =30) according to treatment modalities.The control group was routinely treated.The treatment group received continuous veno-venous hemofiltration (CVVH) for 10-14 days plus routine measures.After 3 days,the score of acute physiology and chronic health evaluation-Ⅱ (APACHE-Ⅱ) of the treatment group was better than that of the control group (P ＜ 0.01).And sequential organ failure assessment (SOFA),left ventricular end diastolic diameter (LVEDD),left ventricular end systolic diameter (LVEDS) and left ventricular ejection fraction (LVEF) improved significantly (P ＜ 0.05).And the relevant blood biochemical parameters improved significantly better than the control group (P ＜ 0.05).In the group CVVH,there were mortality (n =7,23％) and multiple organ failure (MODS) (n =6,20％) ; In the control group,mortality (n =14,50％) and MODS (n =13,46％).The mortality rate had inter-group differences of statistical significance (x2 =4.38,P ＜0.05).Thus early volume resuscitation plus CVVH had excellent curative efficacies for septic shock.

Objective To study the effects of curcumin mediated photodynamic therapy (PDT)on the growth and proliferation in human cervical cancer cell line H8 in vitro and in vivo,and to investigate its antitumor mechanisms.Methods The effects of curcumin mediated PDT on proliferation of human cervical cancer H8 cell by MTT assay was used to screen the optimal parameter.Changes in cell morphology were observed by May-Gr ünwald-Farbstoff Giemsa staining.The apoptosis rate was estimated by flow cytometry.The effect of PDT by curcumin on the expressions of Bcl-2,P53 and survivin in H8 cells was detected by fluorescence real-time reverse transcription-polymerase chain reaction (RT-PCR).Forty BALB/C nude mice underwent subcutaneous injection of H8 cell line so as to establish animal models,and then were randomly divided into four equal groups:control group,irradiation alone group,curcumin alone group,curcumin PDT group.HE staining and pathological examination were performed.Immunohistochemical study was conducted to detect the protein expression of the apoptosis inhibiting genes of Bcl-2.Results The proliferation inhibition of H8 cells was obvious after PDT when curcumin 5μmol/L with irradiation 100 J/cm2,and with dose dependent manner.Typical morphologic features of apoptosis appeared characterizedly by marked chromatin condensation,nuclear pyknosis and fragmentation,and the appearance of apoptotic bodies.The total apoptosis rate was higher in PDT group [(47.21 ± 4.11)％]than in control group(1.71 ±0.16) ％ (P＜0.01).The mRNA expression of Bcl-2,P53 and survivin in H8 cells were suppressed significantly.HE staining showed remarkable subcutaneous necrosis in the PDT group.Immunohistochemistry showed remarkable down-regulation of protein expression of Bcl-2(P＜0.01).Conclusions Curcumin-mediated photodynamic therapy has a significant killing effect on H8 cells in vivo and in vitro.Its antitumor effect might be related to induction of Tumor cell apoptosis and suppression of Bcl-2 mRNA and protein expression.
