The postpartum depression outcome and the effect of psychological intervention were studied in order to reduce the occurrence and development of the postpartum depression. A survey of 4000 women within 4-6 weeks postpartum in 80 communities in Shenzhen, China was performed using random cluster sampling method. By employing Edinburgh Postnatal Depression Scale (EPDS) as a screening tool, the positive women (defined as EPDS ≥10) were randomly divided into intervention group and control group at a ratio of 1:2. The women in the intervention group were treated by means of mailing postpartum depression prevention and treatment knowledge manual, face-to-face counseling, and telephone psychological counseling interventions aiming at individual risk factors, while those in the control group were treated with conventional methods. EPDS scores were assessed in these two groups again at 6th month postpartum. Totally, 3907 valid questionnaires were obtained. All the 771 positive women were divided into two groups: 257 in the intervention group, and 514 in the control group. At 6th month postpartum, the EPDS scores in the intervention group were decreased significantly, from baseline stage (12.84±3.02) to end stage (3.05±2.93), while EPDS scores in the control group were reduced from 12.44±2.78 to 6.94±4.02. There were significant differences in the EPDS scores at end stage between the two groups (t=13.059, P<0.001). Psychological intervention can reduce postpartum depression, with better maternal compliance. It is feasible and necessary to establish postpartum depression screening and psychological intervention model in community-hospital and include the postpartum depression screening, intervention, and follow-up into the conventional healthcare.

Connexin43 has been shown to play a pivotal role in wound healing process. Wound repair is enhanced by acute downregulation of connexin43, by increasing proliferation and migration of keratinocyte and fibroblast. Angiogenesis is also a central feature of wound repair, but little is known about the effects of connexin43 modulation on functions of endothelial cells. We used connexin43 specific small interference RNA (siRNA) to reduce the expression of connexin43 in human umbilical vein endothelial cell (HUVEC), and investigated the effects of connexin43 downregulation on intercellular communication, viability, proliferation, migration and angiogenic activity of HUVEC. Treatment of siRNA markedly reduced the expression of connexin43 by -80% in HUVEC (P < 0.05), and decreased the intercellular communication by -65% (P < 0.05). The viability, proliferation, migration and angiogenic activity of HUVEC decreased significantly (P < 0.05), compared with that of the normal cells. The results suggest that temporally downregulation of connexin43 expression at early stage of wound to inhibit the abnormal angiogenesis characterized with leaky and inflamed blood vessels, maybe a prerequisite for coordinated normal healing process.

Objective To study the expression and value of CXCR1 and CXCR2 on neutrophils, CD14~+ monocytes and CD3~+ T lymphocytes of peripberol blood of ankylosing spondylitis(AS)patients and to investigate the correlation between CXCR1,CXCR2 and disease activity.Methods A case control study was designed and enrolled 30 active AS,30 active rheumatoid arthritis(RA)and 30 healthy controls.The levels of CXCR1 and CXCR2 expression on neutrophils,CD3~+ T cells and CD14~+ monocytes of peripheral blood of the patients and healthy controls enrolled were measured and analyzed by flow cytometry by measuring the mean fluorescence intensity(MFI)channel.The correlations between the level of CXCR1 and CXCR2 anti disease activity or functional index of AS such as BASDAI,BASF1,ESR and CRP were analyzed.Results The MFI of CXCR1 expression on CD3~+ T lymphocytes of peripheral blood was significantly higher in AS patients (41?24)than that in RA patients(18?10)and healthy controls(19?7)(P

The epitope-G1 gene of Bovine ephemeral fever virus (BEFV) glycoprotein was synthesised by PCR and cloned into expression vector pPIC9K to construct recombinant plasmid pPIC9K-G1. Then the pPIC9K-G1 was linearized and transformed into Pichia pastoris GS 115. The recombinant P. pastoris strains were selected by a G418 transformation screen and confirmed by PCR. After being induced with methanol, an expressed protein with 26 kDa molecular weight was obtained, which was much bigger than the predicted size (15.54 kDa). Deglycosylation analysis indicated the recombinant G1 was glycosylated. Western blot and ELISA tests, as well as rabbit immunization and specificity experiments indicated that the target protein had both higher reaction activity and higher immunocompetence and specificity. The recombinant G1 protein could be used as a coating antigen to develop an ELISA kit for bovine ephemeral fever diagnosis.

BACKGROUND AND OBJECTIVEChemotherapy is the main treatment for colon cancer, while multidrug-resistance is the main reason for chemotherapy failure and tumor relapse. This study was to establish two oxaliplatin-resistant colon cancer cell lines and evaluate their biological characteristics.
METHODSOxaliplatin-resistant colon cancer cell lines SW620/L-OHP and lovo/L-OHP were established in vitro by continuous exposure to oxaliplatin (L-OHP) of low and gradually increased concentration. Growth curve, cross-resistance and resistance index of the oxaliplatin-resistant cell lines to various anti-cancer agents were determined by CCK8 assay. The expressions of P-glycoprotein (P-gp), multidrug-resistance protein 1 (MRP1) and MRP2 were detected by Western blot. Cell cycle distribution as well as the expression of CD133 and CD44 were measured by flow cytometry.
RESULTSIt took 10 months to establish the SW620/L-OHP and LoVo/L-OHP cell lines with stable resistance to oxaliplatin. Cross-resistance to 5-fluorouracil, etoposide, cisplatin, vincristine and epirubicin but not to paclitaxel was observed. Longer doubling time, higher proportion of cells in G(0)/G(1) phase and lower proportion in G(2)/M phase were observed in the two oxaliplatin-resistant cell lines compared with their parental cell lines. The expression of MRP2 in the oxaliplatin-resistant cells was up-regulated, while those of P-gp and MRP1 had no significant change. CD133 was overexpressed while CD44 level remained unchanged in SW620/L-OHP and LoVo/L-OHP cells.
CONCLUSIONSSW620/L-OHP and LoVo/L-OHP cell lines show a typical and stably resistant phenotype and may be used as research models.

BACKGROUNDSurgery of pituitary adenomas invading cavernous sinus has always been thought as a challenge due to the complex anatomical structures and high risk of complications. The purpose of this study was to evaluate endoscopic transsphenoidal approach to pituitary adenomas invading cavernous sinus.
METHODSThe clinical data of 22 patients who admitted to Xuanwu Hospital with pituitary adenomas invading cavernous sinus were analyzed retrospectively. All patients underwent endoscopic transsphenoidal surgery. To expose the surgical field sufficiently, the opening of sellar floor was exceeded the bone overlying the invaded cavernous sinus, and synthetic dura was used to repair and strengthen the sella floor for preventing the leak of cerebrospinal fluid.
RESULTSAmong 22 patients, total resection was achieved in 14, subtotal resection in 5, and partial resection in 3; no patient underwent insufficient resection. Visual symptoms improved in 7 of 9 patients. In one patient diplopia disappeared. Headache was relieved to various extents in all patients. No serious complications were found. Patient's hospital stay ranged from 7 to 20 days.
CONCLUSIONThese data suggest that the endoscopic transsphenoid approach is a safe, minimally invasive, and efficient surgical technique, which might be an important therapeutic strategy for the pituitary adenoms invading cavernous sinus.
