Objective To analyse and understand the main reasons for cesarean section,in order to reduce the rate of cesarean section. Methods Clinical analysis was performed in 6781 patients who underwent cesarean section from January 2004 to December 2008. Results ①Cesarean section rate was increasing from 2004 to 2008, which was 32. 00% (840/2625) , 35. 00% (966/2760) , 39. 08% (1186/3035), 45. 98% (1669/3630) and 51. 88% (2120/4086) .respectively. Compared to 2004, the cesarean section rate in 2008 increased significantly (P <0.01). ②The proportion of the main cesarean section indications changed, the proportion of social factors ,fetal factors and maternal factors were increasing gradually. Cephatopelvic disproportion in 2008 decreased significantly compared to that in 2004(x2 = 194. 805 ,P <0. 01). There was significent difference in each indication from 2004 to 2008. Conclusions The cesarean section rate has increased due to medical reasons and social reasons. To ensure the safety of the mothers and children, vaginal delivery should be adopted as far as possible. The cesarean section without medical indication should be prohibited.

Four bacterial and 8 fungal isolates were incubated in media for 6 days. It was found that organic acid content in the media increased largely, but pH decreased sharply. Phosphorus content in the media enhanced dramatically as well. The fungal isolates showed stronger ability to dissolve phosphate rock than the bacterial ones. These isolates excreted not only quite distinct volume of organic acids but diverse organic acid chemicals. The fungi produced more kinds of organic acids than the bacteria. However, there was no significant relationship between the total quantity of organic acids and P content in the media.

Objective To explore the association between clinical pathological characteristics and the expressions of epidermal growth factor receptor (EGFR) and protein kinase B (AKT) in gastric carcinomas.Methods The expressions of EGFR and AKT were measured with immunohistochemical method in the cancer tissues and cancer-adjacent normal tissues from 153 cases of patients with gastric cancer.The association between clinical pathological characteristics and their expressions were analyzed.Results The expressions of AKT and EGFR in gastric cancer tissues had no relationship with gender,age,pathological type,and the degree of differentiation (P ＞ 0.05).A positive correlation was existed between the EGFR and TNM stages (x2 =5.43,P ＜0.05).The AKT was positively related to the size,T stage,and TNM stage of the tumor,respectively (x2 =4.73,4.95,5.32,P ＜0.05 orP ＜0.01).The levels of AKT (x2=4.83,4.75,P ＜0.05) and EGFR(x2 =4.67,4.58,P ＜0.05) in the gastric cancer tissues with lymph node and/or distant metastasis were significantly higher than the gastric cancer tissues without metastasis,respectively.Conclusions The over-expressions of AKT and EGFR would benefit the diagnosis and stages of a gastric cancer and the determination of its metastasis.

Objective: To investigate the colorectal tumor formation and metastasis of circulating tumor cells in nude mice. Methods: Human colorectal cancer HCT116-luc cells labeled with luciferase were implanted between the mucosa and the base of the cecum wall in nude mice. The circulating tumor cells in peripheral blood in nude mice were screened by epithelial cell adhesion molecule (EpCAM) immunomagnetic beads. The EpCAM-positive (EpCAM+) cells and the EpCAM-negative (EpCAM) cells were injected into the tail vein of the nude mice, respectively, then the tumor formation and the metastases in lung and liver in nude mice were observed. Results: The orthotopic transplanted tumor model of colorectal cancer in nude mice was successfully constructed. The tumor formation rate of EpCAM+circulating tumor cells in nude mice was 90%, the metastasis rates in lung and liver were 60% and 40%, respectively, and the metastasis rate in both liver and lung was 35%. There was no tumor formation of EpCAM circulating tumor cells in nude mice and also no metastasis occurred. The tumor formation rate and the metastasis rate between EpCAM+ and EpCAM groups had statistical differences (all P < 0.01). Conclusion: The tumor formation of EpCAM+ circulating tumor cells in nude mice is good, and the tumor prones to metastasis.

Objective To analyze clinical management and outcomes of perinatal fetuses born in triplet and multiple pregnancy.Methods Data of clinical management and outcomes of 55 perinatal fetuses born during 1996 to 2005 by women with triplet and multiple pregnancy were analyzed retrospectively.Results Antenatal check-up was performed regularly for 1/6 of those pregnant women during 1996 to 2000,as compared to that of 8/11 during 2001 to 2005(P<0.05).No significant difference in incidence of varied obstetric complications was found between those during 1996 to 2000 and during 2001 to 2005.Average gestational week at birth was(32.7±2.8)and(35.1±1.9)weeks(P<0.05),and averagebirth weight was(1561±471)grams and(1987±453)grams(P<0.01),respectively for them during 1996 to 2000 and during 2001 to 2005.Caesarean section was performed more for the pregnant women in the earlier first five years than in the later five years,but not reaching statistical significance.Incidence of neonatal complications significantly decreased in the later five years than that in the earlier five yeats,including hyaline membrane disease,neonatal asphyxia,infectious diseases,intracranial hemorrhage and pulmonary hemorrhage(P<0.05),but difference in incidence of apnea and low body temperature between the earlier and later five years did not reach statistical significance.Perinantal mortality was 8 in 35 births in the later five years,as compared to that of 12 in 20 births in earlier five years(P<0.01).Conclusions Outcomes of perinatal fetuses in triplet and multiple pregnancy can be improved by combined action of obstetricians and pediatricians,including regular antenatal examination,active prevention and treatment for pregnant complications and preterm infant diseases,earlier admission waiting for delivery to prolong gestational weeks and increase birth weight,and applying antenatal dexamethasone therapy.

Human infections with novel avian influenza A(H7N9)virus was an emerging infectious disease discovered in March, 2013. As of June30, 2016, 770 cases of H7N9 were reported in worldwide including 315 deaths with 40.9% of high case fatality rate. Yangtze River Delta and Pearl River Delta were the high-prevalence area. Formerly, the cases of H7N9 were concentrated on the municipalities. However, most of the case-patients were from smaller cities or rural areas nowadays. The H7N9 human infections mainly occurred in winter and spring every waves as similar as seasonal and H5N1 human infections. Middle aged and old (the median age was 61 years) male patients were occupied the large proportion among the cases of H7N9. In addition, the phenomenon of the limited and unsustained human-to-human transmission were existed. At present, the 4 major epidemic waves had happened and human infections with novel avian influenza A (H7N9) virus could be outbreak regularly in China. In this paper, the pathogenic characteristics and disease distribution of H7N9 influenza A viruses were elaborated, with both transmission factors and control measures, which were helpful to provide the scientific evidence for prevention and control in H7N9avian influenza epidemic.

The key of harmonious relationship is to perform effective humanistic caring for patients, to change the service model, to perfect the attitude of service; the patients should seek scientific medical help and adopt a rational attitude towards possible medical accidents. Thus the kind of concordant ambience will come into being in medical treatment.

Objective To analyze the relationship between pain sensation, emotion and recognition in three dimensions. Methods By using questionnaires which contained general information questionnaire, Cancer Pain Questionnaire, Self-reporting Inventory (SCL-90), Pain Beliefs and Perceptions Inventory (PBPI) to investigate pain sensation, emotion and recognition of 46 patients with cancer pain. Results There were 13(28.3%) cases sufferd from mild pain,17 (37.0%) cases were moderate pain, 16 (34.8% )cases were severe pain.As to the result of SCL- 90,patients showed obvious symptom in somatization, depression, anxiety and hostility.They holded deep belief of that pain was very mysterious. There was a significant correlation between pain severity and depression(rs=0.377) , anxiety(rs=0.388) on the condition that confidence level was 0.01;there was also a significant correlation between pain degree and interpersonal sensitivity(rs=0.308), hostility(rs=0.320) on the condition that confidence level was 0.05. As to pain beliefs, pain degree had a significant correlation with it in the dimension of pain as mystery (rs=0.529) and pain was persistent(rs=0.680) on the condition that confidence level was 0.01. Conclusions The survey shows a positive correlation between pain severity,emotion of pain(such as anxiety,depression, hostility and interpersonal sensitivity)and beliefs about pain as mystery or permanent.

Objective To investigate the present situation and analyze the influence factors of self-management ability of schizophrenic patients in community. Methods A total of 122 cases of schizophrenic patients in community that have been discharged from Zhenjiang Mental Health Center were investigated and analyzed by general information questionnaire, Schizophrenia Self-Management Ability Scale, quality of life and Social Support Rating Scale. Results The scores of self-management ability of schizophrenic patients in community were (68.74 ± 10.24) points. Multiple stepwise regression analysis showed that long-term medication (t =2.351, P<0.05), degree of education(t =2.385, P<0.05), community rehabilitation guidance (t =3.813, P<0.01) and social support (t=2.768, P<0.01) were the influence factors of self-management ability of schizophrenic patients in community. Conclusions Schizophrenia patients in community medical staff should be aimed at strengthening the long-term medication in community rehabilitation guidance and social support, improvement, and strengthen the low degree of culture of patient care, to improve the ability of self-management.
