Comparing with the world level, the bibliometric indicators of Chinese medical journals in oncology field are rather lower, but our medical journals have big development space. In the world journals with high impact index, the papers published by Chinese authors are fewer; in the papers number, the superiority of Chinese authors is in tumor clinical therapy field. Most papers are written by researchers from large institutions with plenty of medical resources.

Objective To explore the influential factors of dangerous placenta previa pathogenesis,and to analyze their peri natal period outcomes.Methods The clinical data in 143 pregnant women and parturients of dangerous placenta previa(research group) and 286 pregnant women and parturients of non-dangerous placenta previa(control group) in our hospital from January 2011 to December 2015 were retrospectively analyzed.Results The average age of the research group was higher than that of the control group (t =2.92,P =0.004);the previous pregnancy frequency,previous parity,previous abortion frequency,previous cesarean delivery frequency and incidence of placenta previa in the research group were higher than those in the control group(P＜0.01);the incidence of placenta previa in the research group was higher than that in the control group(x2 =7.60,P=0.006);the prenatal gestational weeks of the research group were lower than those of the control group(t=-12.33,P＜0.01).The multi-factor analysis showed that the age,previous abortion frequency and previous cesarean delivery frequency were the influence factors of placenta previa occurrence.Among them,the previous cesarean delivery frequency was the main risk factor.The occurrence rates of antepartum hemorrhage,postpartum hemorrhage,uterine removal and premature infants in the research group were higher than those in the control group(P＜0.01);The intraoperative blood loss of the research group was higher than that of the control group(P＜0.05);the neonatal birth weight and the 1 min Apgar score of the research group were lower than those in the control group(P＜0.05).Conclusion The age,previous abortion frequency and previous cesarean section frequency are related to the occurrence of dangerous placenta previa.

Objective To establish the sensitive,specific,stable and convenient immunoradio assay for detecting human soluble IL-6R?.Methods The hybridoma cell lines were obtained by fusing spleen cells of BALB/c mice that had been immunized with soluble IL-6R? protein to mouse myeloma cells sp2/0. Ascites were used to produce the monoclonal antibodies (mAbs). The mAbs were purified by protein G immunoaffinity method. The mAb SI10 was used as coating antibody, the other mAb H126 recognized different epitope from SI10 was labeled by 125I. Results The immunoradio assay for detecting soluble IL-6R? was set up. It has high stability and accuracy. The detecting limit is 10 ng/ml. The serum concentration of soluble IL-6R? is (81.96 ? 7.23) ng/ml in healthy donors and (237.58?70.96) ng/ml in patients with multiple myeloma. Significant difference was founded between two groups (P

OBJECTIVE To investigate approaches to the prevention of sharps injuries. METHODS A retrospective questionnaire was performed for 193 nurses of a general hospital from the time of Jan 2004 to Jun 2005. RESULTS The questionnaires indicated that 46.1% nurses had suffered sharps injuries,with averaged of 1.6 times per person,of which 36.7% and 32.4% were caused respectively by syringe needles and glass wares.Opening ampules,disposal of used sharps,installing the syringe needles and transmitting sharp devices were the four major events in which sharps injuries might happen,accounted for 29.5%,22.3%,15.8% and 10.1%,respectively.It is also noted that 79.1% nurses suffering from the injury wore no gloves. CONCLUSIONS Occupational hazards of sharps injuries are threatening nurses.Certain prophylactic measures should be taken to control and prevent sharps injuries.

Objective:To observe clinical significance between changes of OPN,IL-18 levels and relation ship with hepatic function in patients with chronic hepatic disease infected by HBV.Methods:The levels of OPN,IL-18 in peripheral blood of 102 patients with chronic hepatitis B,34 patients with hepatitis B-related cirrhosis,95 HBV carriers and 20 healthy people as the control group were respectively detected with ELISA.Results:The levels of OPN and IL-18 in chronic hepatitis B and hepatitis B-related cirrhosis groups were significantly increased compared with that of health control group(P

Objective To explore the association of sedentary behavior and time with risk of metabolic syndrome (MS).Methods A total of 10 149 subjects were recruited from local residents aged ≥40 years old in Jiashan County by cluster-random sampling method.The data including physical activity,job,sedentary time,and sleep,etc.were collected.Height and body weight,waist circumference,blood pressure,blood glucose,blood lipid,etc.were determined.Logistic regression was used for correlation analysis.Results The prevalence of MS was 28.64％ in local residents over 40 years old in Jiashan.The rate of sedentary behavior in all subjects was 67.57％,with 3 h sedentary time on average.Compared with non-MS group,the rates of sedentary behavior and sedentary time were significantly higher in MS group (P＜0.01).Multivariate logistic regression analysis showed that sedentary behavior was independently associated with an increased risk of MS after adjustment for age,sex,body mass index (BMI),smoking,drinking,and sedentary time(OR=1.16,95％ CI 1.03-1.30,P=0.017).Increased sedentary time was associated with higher risks of hypertension,type 2 diabetes mellitus,and dyslipidemia (P ＜ 0.05 or P ＜ 0.01).Sedentary time ≥ 5 h/d independently increased the risk of MS (OR =1.15,95％ CI 1.01-1.31,P =0.034).Conclusions There is a high prevalence of MS in adults over 40 years old living in the eastern coastal rural area.MS and its related diseases are closely associated with sedentary behavior and its duration.

BACKGROUND: Ghildren refractory clubfoot includes idiopathic multiple contracture, untreated idiopathic clubfoot in older children and failure cases of repeated operations. It is very difficult to treat this type of children patients. It has important significance in the exploration of new therapeutic methods.OBJECTIVE: To improve the therapeutic effectiveness of refractory clubfoot in children with Ilizarov method.DESIGN: a self-controlled study.SETTING: Department of Orthopedics, Nanjing Children' s Hospital, Nanjing Medical University.PARTICIPANTS: Totally 3 cases of children idiopathic multiple contracture, 2 cases of idiopathic clubfoot in children aged more than 10 years old without treatment and 6 cases of postoperative recurrent idiopathic clubfoot were admitted by the Department of Orthopedics of Nanjing Children' s Hospital Affiliated to Nanjing Medical University during 1999 to 2000. All cases manifested abnormal ankylosis and shortening deformity in foot.METHODS: Twelve refractory clubfeet in eleven patients were treated with the Ilizarov method. After achilles tendon lengthening and posterior release,kieschner' wires or olive wires with tension were penetrated through multiple planes of the middle lower 1/3 of tibia, calcaneus and the 1st to the 5th metatarsals, which were fixed respectively to external bone fixer of a ring,half-ring or horseshoe shape and connected with each other by multiple screw bars into a three-dimensional external bone fixing set. Plantarflexion, inversion, adduction and shortening deformities were corrected by the adjustment of the distance between each part of the external bone fixing set through extension, compression, and rotation, etc., and navicular and cuboid osteotomy.MAIN OUTCOME MEASURES: All 11 cases were followed up for 2 to 10 years with an average period of 4. 5 years. Indices like foot morphology,talocrural articualr activity range and deformity correction were observed during the follow up.RESULTS: The results were excellent in 5 cases (6 feet), good in 4 cases (4 feet), fair 2 cases(2 feet) according to the Garceau standard scale. The rate of excellent and good clinical results was 83.3%. Mild forefoot adduction was left in 2 feet of 2 cases and quite obvious tarsal articular ankylosis was found in 4 feet of 4 cases; however, there were no significant differences of gait and load bearing between these patients and normal children.CONCLUSION: The Ilizarov technique is a safe and effective method for the treatment of refractory children clubfoot while its indications should be controlled strictly.

normal pregnancy and RSA (P=0.0250).Compared with women with normal pregnancy, those with RSA showed significantly decreased levels of Arg-1 ( P=0.0474) and suppressed activities of MDSCs against CD8+T cell proliferation (P=0.0230).Conclusion The MDSCs might play an important role in the main-tenance of maternal immune tolerance.Decreased number and inhibited function of MDSCs in the peripheral blood of women with RSA might be responsible for the development of RSA.

Objective To investigate the effects of ch1D1, an anti-CD86 chimeric antibody, on autoreactive B lymphocytes isolated from patients with systemic lupus erythematosus ( SLE) . Methods Flow cytometry analysis was performed to measure the expression of CD86 on the surface of B cells isolated from patients with SLE and to analyze the effects of ch1D1 on the activation of CD4+T cells. The method of magnetic bead sorting was used to separate B cells, NK cells and CD4+T cells from PBMC collected from healthy subjects and patients with SLE for subsequent experiments. Antibody-dependent cell-mediated cyto-toxicity (ADCC) and complement-dependent cytotoxicity (CDC) that were mediated by ch1D1 were meas-ured with LDH release assay. Effects of ch1D1 on the secretion of auto-antibodies and the proliferation of CD 4+ T were detected by ELISA and 3 H -thymidine ( 3 H-TdR) incorporation assay, respectively. Results The levels of CD80 (68. 08±14. 28 vs 46. 10±12. 14, n=24, P<0. 000 1) and CD86 (44. 72±14. 90 vs 13. 99±10. 74, n=24, P<0. 000 1) expressed on the surface of B cells isolated from patients with SLE were significantly higher than those from the healthy subjects, suggesting the abnormal activation of B cells. Com-pared with the negative control group and the murine monoclonal antibody 1D1, ch1D1 was more effective in mediating the ADCC and CDC responses (P=0. 017 2, P=0. 038 8). Activated T cells significantly en-hanced the secretion of auto-antibodies by B cells isolated from patients with SLE. Compared with the nega-tive control group, the enhanced secretion of auto-antibodies was significantly inhibited by treatment with ch1D1 (P=0. 001 9). Moreover, ch1D1 significantly inhibited the proliferation and activation of CD4+T cells induced in patients with SLE (P=0. 002 4, P=0. 049 5). Conclusion ch1D1, the anti-CD86 chim-eric antibody, could effectively mediate the ADCC and CDC responses against autoreactive B cells isolated from patients with SLE, inhibit the secretion of auto-antibodies and suppress the proliferation and activation of auto-reactive CD4+T cells. It might be a potential immunotherapy agent for the treatment of SLE.
