Objective This paper aims at the therapeutic effect aft er the artifitial abortion by employing the TCM periodic treatment with respect to shortening the vaginal bleeding time and accelerating the uterine lining recovery. Methods Sampling 280 cases of artifitial abortion in early pregnancy, the author divides them at random the testing and control groups with each of the membership of 140 cases. Given the Nifuratel perorally same as the control group, the testing group is additionally under the TCM periodic treatment, that is, dosing Chinese medicine with the purpose of eliminating blood stasis,promoting tissue regeneration as well as invigorating the vital energy and nourishing the blood during the 1 to 3 days'postoperation period, giving Chinese medicine with a view of strenthening liver and kidney together with activating vital energy during the 4 to 14 days' postoperation period, instructing Chinese medicine in order to nourish the spleen and kidney as well as regulate Chong and Ren Vessels during the 15 to 25 days' postoperation period perorally and respectivelly. In contrast, the control group is given Xuefuzhuyu Capsules after the whole postoperation period. Results In terms of the time of vaginal bleeding, menstrual recovery and the regenerating condition of the uterine lining, the result (except for 3 cases in testing group and 2 cases in control group quiting the experiment) shows that after treatment (9 days after the abortion) the testing group achieves the effect superior to that of control group (P＜0.01). Conclusion The conclusion is that the TCM periodic therapy is effective in the aspect of shortening the vaginal bleeding time, accelerating the uterine lining recovery and regulating the menstrual circle.

Objective To investigate the relationship between inflammatory response and depth of propofol sedation during cardiac valve replacement with cardiopulmonary bypass (CPB).Methods Fifty patients undergoing cardiac valve replacement with CPB were randomly divided into low Bispectral index (BIS)group(30≤BIS<45)and high BIS group(45≤BIS≤60).Each group had 25 cases.The induction of anesthesia in the two groups was in the same way.Anesthesia was maintained in the fol‐lowing way :low BIS group and high BIS group received intravenous infusion of 7 mg/(kg · h) and 3 mg/(kg · h) propofol ,re‐spectively.In operation ,the propofol infusion rate was adjusted to maintain each group in the corresponding BIS value range.Before induction of anesthesia(T0 ) ,at the end of the CPB(T1 ) ,the end of operation(T2 )and 1 h after operation(T3 ) ,re‐spectively ,6 mL of jugular vein blood samples were collected.The concentrations of IL‐6 ,TNF‐αand S100βprotein in the serum were detected by ELISA method.At T0 ,T1 and T2 ,respectively ,arterial blood was collected ,the pH of blood and the concentra‐tions of blood glucose and lactate were determined.Results At T1 ,T2 and T3 ,the concentrations of IL‐6 and TNF‐αin serum in low BIS group were all lower than those in the high BIS group(all P<0.05).At T2 and T3 ,the S100βprotein concentrations in serum in the low BIS group were all lower than those in the high BIS group (both P< 0.05).Compared with the high BIS group ,the concentrations of blood glucose and lactate in low group at T 1 and T2 were all lower(all P<0.05).Conclusion Ap‐propriately enhancing the depth of sedation could help relieve the inflammatory reaction of patients during cardiac valve replace‐ment with CPB.It can help protect brain tissue and reduce the incidence of brain injury.

[ ABSTRACT] AIM:To explore the effects of transcription factor HOXB7 silencing on the viability , invasion and migration of SGC-7901 cells.METHODS:The siRNA was designed to specifically interfere the expression of HOXB7.To assess the silence efficiency of the siRNA , the expression of HOXB7 at mRNA and protein levels was detected by real-time PCR and Western blot in the SGC-7901 cells transfected with siRNA .The cell viability was measured by MTT assay .Cell cycle-related proteins such as cyclin D 1 and CDK4 were determined by Western blot .Transwell assay was performed to an-alyze the migration ability of the SGC-7901 cells.The mRNA and protein levels of the tumor invasion-and metastasis-relat-ed molecules, such as VEGF, PTEN and p-AKT, were also detected by real-time PCR and Western blot .RESULTS:The expression of HOXB7 at mRNA and protein levels was higher in the gastric carcinoma tissues than that in the normal gastric tissues.The expression of HOXB7 at mRNA and protein levels was knockdown by siRNA .After silencing of HOXB7 gene expression, the viability of the SGC-7901 cells decreased, the expression of cyclin D1, CDK4 and VEGF was down-regula-ted, and the phosphorylation level of AKT was also obviously decreased .CONCLUSION:HOXB7 effectively promotes the viability, invasion and migration of gastric carcinoma cells by up-regulating the expression of cyclinD 1, CDK4 and VEGF, and increasing the phosphorylation level of AKT to inhibit PTEN function .

The estimation of a-tocopherol in human blood was carried out by gas chromatography. The cholesterol in plasma must he removed in advance. The a-tocopherol is chromatographed as tocopherol acetate and is eluted with a retention time of about 8 min. Tetratriacontane was used as internal standard. The average recovery rate was 76.4 per cent and coefficient of variation was 4.4 per cent (N = 10). The mean level in 25 cord blood was 2.1 ?0.5 ?g/ml. It correlated well with the results by spectrophotome-tric method (r=0.6803 P

AIM: To study and explore whether the antisense phosphorothioate oligodeoxynucleotides (ASODN) of bcl-2 oncogene would increase the apoptotic effect of As 2O 3 on NB4 leukemic cells. METHODS: The biological and morphological changes in NB4 cells from microculture with As 2O 3, bcl-2 ASODN or both were observed. The changes in DNA content and Bcl-2 protein of NB4 cells from microculture with As 2O 3, bcl-2 ASODN or both were determined by tissue chemistry and flowcytometry. RESULTS: There was much more apoptotic effect of As 2O 3 on NB4 cells while it combined with bcl-2 ASODN (ASODN 10 0 ?mol/L+ As 2O 3 0 25 ?mol/L) than alone(ASODN 10 0 ?mol/L or As 2O 3 0 25?mol/L),and so did inhibitory effect of Bcl-2 protein expression by flow cytometry. CONCLUSION: The bcl-2 ASODN can enhance the apoptotic effect of As 2O 3 on NB4 leukemic cells. [

B-cell lymphoma is a heterogeneous group of disorders involving malignant proliferation of B lymphocytes, accounting for approximately 85%of non-Hodgkin lymphoma. Combined use of rituximab and chemotherapy remarkably improves the survival of pa-tients with B-cell lymphoma. Despite the increase in treatment response, some patients suffer relapsed or refractory lymphoma. Nu-merous novel treatment options have been developed in pre-clinical and clinical practice, including targeted therapies, auto-hemato-poietic stem cell transplantation, cellular immunotherapy, and radioimmunotherapy. This review describes recent advances in B-cell lymphoma treatment and discusses future perspectives.

Ten years had passed for the molecular targeted therapy since approval by the U.S.Food and Drug Administration of the first monoclonal antibody-Rituximab,for the treatment of the B-cell non-Hodgkin's lymphomas with positive CD20- The targeting therapy,which may be a promising approach in the future,has significantly improved the patients'qualities of lives and prognosis because it has higher selectivity and less adverse effects than current chemotherapy and radiotherapy.In the past decade,with the fast development of novel targeting drugs and extension of therapeutic fields,the limitations associated with the targeted treatments were received attentions.

Objective To investigate bone nutritional status of neonates and their mothers as well as the correlation between them by estimating the concentrations of 25-(OH)D3, calcium and phosphorus in maternal blood and cord blood at birth, and by measuring the bone speed of sound (SOS) of neonates and their mothers with quantitative ultrasound within 3 days after birth. Methods The concentrations of 25-(OH)D3, calcium and phosphorus in the serum were estimated both from 32 pregnant women who had a term delivery and from the umbilical cord at birth. Within 3 days after delivery, the bone SOS values of the mothers measured from their radius and neonates from their tibia were estimated and the correlation between the mothers and their neonates was analyzed. Thirty-nine non-pregnant healthy women who at the same age as the pregnant women were selected as control group and had their bone SOS measured. The difference of bone SOS between pregnant and healthy non-pregnant women was compared. Results There was positive correlation between cord blood and maternal blood 25-(OH)D3 concentration [(14. 7±7. 8) nmol/L and (30. 3±10. 2) nmol/L, r= 0 . 680, P=0. 000]. The calcium and phosphorus concentration in cord blood [2.36±0. 28)mmol/L and (1.57±0.76) mmol/L] were significant higher than that in maternal blood E(2.09± 0. 17) mmol/L and (1.04±0. 28) mmol/L], but no correlation was found (r=0. 146, P=0. 467; r=0. 148, P=0. 445). No significant correlation was shown in the bone SOS between the infants and their mothers[(3054±76)m/s and (4170+241)m/s, r=0. 223, P=0. 220]. The concentration of 25-(OH)D3 in cord blood was closely correlated with the bone SOS of infants(r=0. 412, P=0. 026). The SOS of healthy women was obviously higher than that of pregnant women [(4258±100)m/s vs (41704±241)m/s, P=0. 043]. Conclusions There are close correlations between fetus and their mothers in vitamin D status and also between vitamin D status and fetus bone development. Some pregnant women may be short of vitamin D in autumn and winter in Shanghai and we should monitor the bone nutritional states for pregnant women.
