Objective To investigate the effect of lie delivery in promoting natural delivery functionsmoothly.Methods One hundred and sixty pregnant women hospitalized and deliveried in the Maternal and Child Care Service Centre of Shijiazhuang from June 2013 to June 2014 were randomly divided into observation group of lie delivery and control group of bladder lithotomy postion delivery,80 cases in each group,The second stage of labor time,postpartum hemorrhage (2 h ＞ 500 ml),postpartum comfort and neonatal asphyxia (Apgar score ≤ 7 points) of two groups were observed and compared.Results The second stage of labor time of observation group was significantly shorter than that of the control group taking lithotomy position childbirth,and thepostpartum hemorrhage (2.5％ vs 7.5％;x2 =3.247,P=0.034),cervical laceration(3.75％ vs 21.25％;x2 =4.657,P=0.047) and the incidence of postpartumdiscomfort incidence(16.25％ vs 50.0％;x2 =18.357,P =0.008) were less than that in the control group,the differences between two groups were statistically significant (P＜0.05).Fetal distress (2.50％ vs 8.75％;x2 =4.672,P =0.030),neonatal asphyxia rate(1.25％ vs 7.50％;x2 =4.142,P =0.035) of two groups have statistical significance (P ＜ 0.05).Conclusion The parturient labor process in lying position to take,can effectively shorten the birth process,reduce the incidence of fetal distress and neonatal asphyxia.

Objective To investigate the expression of CyelinD1 protein in nephroblastoma.Methods The tissue microarray were made in 28 cases of nephroblastoma and 19 cases of renal tissue adjacent to tumor.The expression of CyclinD1 and p53 proteins were detected by immunohistochemistry.Results The positive rate of the expression of CyclinD1 and p53 protein was significantly different between nephroblastoma and renal tissue adjacent to tumor (P < 0.05).The positive rate of the expression of CyclinD1 and p53 protein was significantly different in different degree of differentiation of nephroblastoma (P < 0.05).The expression of CyclinD1 and p53 protein was positively correlated (P < 0.05).Conclusions The CyclinD1 and p53 might be used as the marks for estimating the degree of differentiation of nephroblastoma.The over-expression of CyclinD1 and the mutation of p53 might play the vital role in nephroblastoma.

Objective To investigate the relationship between the onset of lower extremity venous thrombotic disease and seasons.Methods A retrospective study was conducted, 300 patients with lower extremity venous thrombotic disease admitted to HandanCity Hospital of Traditional Chinese Medicine (TCM) from August 2012 to February 2014 were enrolled, the incidences and TCM syndromes of patients with lower extremity venous thrombotic disease in different seasons were observed, and the pathogenesis and relationships between the types of TCM syndrome and seasons were analyzed.Results There were 142 patients with lower extremity superficial thrombophlebitis, and 158 cases with lower extremity deep venous thrombosis, the incidence of lower extremity venous thrombotic disease in spring was significantly higher than that in summer and autumn [32.8% (86/262) vs. 21.3% (54/254), 18.4% (50/272), bothP < 0.01], but lower than that in winter [32.8% (86/262) vs. 37.2% (110/296)], the difference was not statistically significant (P > 0.01); while the incidence of lower extremity venous thrombotic disease in winter was significant higher than those in summer and autumn (allP < 0.01). The incidences of damp and heat downward flow type in autumn and summer were increased compared with those in winter and spring [55.6% (30/54), 60.0% (30/50) vs. 20.0% (22/110), 23.3% (20/86), allP < 0.01], while the incidences of lower extremity venous thrombotic disease with damp heat and stasis syndrome in winter and spring were increased compared with those in summer and autumn seasons [80.0% (88/110), 76.7% (66/86) vs. 44.4% (24/54), 40.0% (20/50)].Conclusions The incidence of lower extremity venous thrombotic disease is related to seasons, and the onset is high in winter and spring, damp heat and stasis syndrome being the main type; according to different seasons, clinical treatment can direct to different pathogenic factors to adopt different preventive measures interfering with the patient's constitution in order to eliminate or reduce the risk factors, achieving the effect of the disease prevention.

Objective To investigate serum NK cell levels in HBeAg positive early pregnancy women with immune activation.Methods Fifty four HBeAg positive pregnant women admitted in Taizhou People's Hospital from September 2010 to April 2013 were enrolled in the study.Among them,the serum HBV DNA load decreased ≥2 log at 12 weeks after pregnancy in 24 cases (immune activation group) and HBV DNA did not decrease in 30 cases (immune tolerance group).The serum level of alanine aminotransferase (ALT),total bilirubin,HBeAg,HBV DNA load and NK cells were measured.Results At week 12 of gestation,the mean ALT levels and ALT abnormality rate in immune active group were higher than those in immune tolerance group [(146.7 ±93.1) vs.(44.1 ± 14.7) U/L,t =2.95,P＜0.05,50.0％ vs.6.7％,x2 =4.97,P ＜0.05].There was no significant difference of HBeAg level between two groups before pregnancy,while HBeAg level in immune activation group was lower than that in immune tolerance group at week 12 week of gestation [(291.8 ± 170.5) vs.(443.7 ± 289.9) S/CO,t =2.81,P ＜0.05].The percentage and absolute number of NK cells in immune activation group were higher than those in immune tolerance group [(26.7 ±9.1)％ vs.(17.1 ±7.8)％,t =2.52,P ＜0.05 and (370.9 ±136.4)/μl vs.(213.2 ±97.8)/μl,t =2.38,P ＜0.05,respectively].Conclusions In HBeAg positive early pregnant women with immune activation,the inhibition of HBV DNA might be associated with the activation of NK cells.

BACKGROUND:Cancer stem cel s have self-renewal ability and can differentiate into new tumors. Cancer stem cel s are the source of tumor formation and recurrence, and they can make tumors insensitive to radiotherapy and chemotherapy.
OBJECTIVE:To explore the effect of paclitaxel plus cisplatin on the proliferation and apoptosis of nasopharyngeal cancer stem cel s (NPCSCs) and involved signal pathways.
METHODS:NPCSCs were sorted by immunomagneticbeads and were treated with paclitaxel, cisplatin or their combination. The expression of caspase-3, activated caspase-3 and Bcl-2, which are related to apoptosis, was determined by western blot. The expression ofβ-catenin and its downstream proto-oncogene, c-myc, was also determined by western blot. The activity of the Wnt/β-catenin pathway was inhibited by knocking downβ-catenin expression orβ-catenin inhibitor XAV939. Proliferation and apoptosis of NPCSCs were detected by MTT and flow cytometry, respectively.
RESULTS AND CONCLUSION:Either paclitaxel or cisplatin could inhibit proliferation and induce apoptosis of NPCSCs. The expression of apoptosis marker, activated caspase-3, was increased and the expression of the inhibitor of apoptosis, Bcl-2, was declined. Combined use of paclitaxel and cisplatin had synergistic effect when used together. Either paclitaxel or cisplatin could inhibit the expression ofβ-catenin and c-myc, suppressed the proliferation and induced the apoptosis of NPCSCs by inhibiting the activity of Wnt/β-catenin pathway. These results indicate that the combined use of paclitaxel and cisplatin may inhibit the proliferation of NPCSCs and promote apoptosis via the Wnt/β-catenin pathway.

The noninvasive measurement of liver stiffness (LS) was evaluated by transient elastography (FibroScan) and the possible influencing factors from the patients' clinical situations including age, gender, liver inflammation represented by alanine transaminase (ALT) and total billirubin (TBIL) level, HBV replication (HBV DNA loads), portal vein pressure (portal vessel diameter, PVD), splenic thickness (SPT) and body mass index (BMI) were analyzed in patients with chronic hepatitis B (CHB). A total of 466 patients including 31 patients with acute-on-chronic liver failure (ACLF), and 435 patients with chronic hepatitis B (CHB) among which 82 patients were diagnosed with liver cirrhosis (LC) by clinical manifestations and liver B-type ultrasonic inspection were enrolled at Tongji Hospital from April to December 2009. LS was measured by a FibroScan device (EchoSens, France). Simultaneously, ALT and TBIL levels, HBV DNA loads, PVD, SPT and BMI in all patients were also tested. Forty-one healthy volunteers served as controls. The values of LS were correlated positively with ages of CHB patients and significantly higher in males than in females. In patients with BMI>28 kg/m(2) (obesity) and abnormal levels of ALT and TBIL, LS values were significantly increased as compared with those having normal levels of ALT and TBIL. The patients with ACLF had the highest LS value. Furthermore, LS values in the patients with LC were significantly higher than those in patients without LC. It is concluded that noninvasive measurement of liver fibrosis by FibroScan provides an alternative method to evaluate liver fibrosis of patients with CHB. In order to properly illustrate the stiffness value taken by transient elastography, patients' gender should be taken into consideration and it is also suggested to avoid possible influencing factors including liver inflammation (high levels of ALT and TBIL) and obesity (high BMI).

OBJECTIVE To evaluate the infection of central venous catheterization in tumor patients with chemotherapy and analyze its risk factors and the role of nursing intervention. METHODS The prospective overall monitoring method was used,including catheterization,maintenance,observation and monitoring. RESULTS Of 446 cases with chemotherapy,the infection rate was 2.24% (10 cases). The infection mainly correlated with age,catheterization time,chemotherapy duration,venous nutrition,complication and hormone. CONCLUSIONS The infection of central venous catheterization is inevitable due to multiple risk factors. The measures to prevent and reduce hospital infection are holding the key steps of central venous catheterization,executing the management system of sterilization,keeping tract smooth,cutting down time of central venous catheterization and strengthening nursing education about central venous catheterization.

Aim To study the effect of genistein on contractility of isolated papillary muscles in guinea pig and its mechanisms.Methods Isolated guinea pig papillary muscles were suspended in organ baths containing KH solution,and the effect of genistein on contractility of myocardium was observed after an equilibration period.Results Genistein and isoprenaline hydrochloride showed positive inotropic effects on contractility of myocardium in a dose-dependent manner(1～100 ?mol?L~(-1)) Propranolol(1 ?mol?L~(-1)) and verapamil hydrochloride(0.5 ?mol?L~(-1)) attenuated the positive inotropic effect of isoprenaline hydrochloride(2 ?mol?L~(-1)),but did not change the effect of genistein(100 ?mol?L~(-1)).Furthermore,the enhancement of the contractility induced by elevation of extracellular Ca~(2+) concentration in papillary muscles did not show any change after pretreatment with genistein(1,10 ?mol?L~(-1)).Finally,the positive inotropic effect of genistein was attenuated partially by tamoxifen(1 ?mol?L~(-1)),however,was not influenced by sodium orthovanadate(1 ?mol?L~(-1)).Conclusions Genistein has the positive inotropic effect on guinea pig papillary muscles,which is not related to the activation of Ca~(2+) channel on cell membrane,? adrenoceptor and tyrosine kinase pathway,but this effect may involve in uptake and utilization of sarcoplasmic reticulum Ca~(2+).

ObjectiveTo explore the clinical diagnosis and surgical treatment of primary retroperitonealneurilemoma(schwannoma). MethodsClinicaldataof 47patientsof primary retroperitoneal schwannoma admitted and surgically treated from January 1995 to December 2009 were retrospectivelly reviewed.ResultsAs diagnosed by pathology there were 36 cases of Benign schwannoma,with a median age at onset of 41years, among those 11 patients were symptomatic, and 25 were asymptomatic. There were 11 malignant 11 cases, the median age was 38 years, among those 6 patients were symptomatic, and 5 were asymptomatic. The positive diagnostic rate of preoperative CT and MRI were 36. 2％ ( 17/47 ) and 58. 3％ ( 7/12 ) respectively. Immunohistochemically positive rates of S-100 were 100％ and 81.8％(9/11) in benign and malignant group respectively.All cases underwent surgical treatment. Surgical resection rates for benign and malignant groups were 100％ and 90. 9％(10/11)respectively. There was no perioperative death, Overall 5-year survival rates were 100％ and 45.5％ for benign and malignant tumors groups respectively. In benign group 2 cases recurred, in malignant group 4 cases recurred, and 3 had distant metastasis.ConclusionsPrimary retroperitoneal schwannomas are less common. It is difficult to make an accurate preoperative diagnosis. Surgery is the most effective therapy.Prognosis is good for benign and poor for malignant retroperitoneal neurilemomas.

A case of ulerythema ophryogenes (UO) is reported.A 12-year-old boy presented with erythema and follicular papules on the eyebrows and cheeks for 7 years.The lesions started as follicular papules surrounded by erythema,then spread symmetrically to the cheeks and forehead followed by the loss of eyebrows.There was no complaint of pruritus.Physical examination showed pinhead- to grain-sized,smooth,slightly indurated follicular hyperkeratotic papules surrounded by erythematous halo on the eyebrows,forehead and cheeks.Both eyebrows were nearly completely lost.Histological analysis of lesions from eyebrows revealed dilated follicular infundibulum with orthokeratotic plugs,sparse perivascular and perifollicular lymphohistiocytic infiltrate,widened and sclerotic collagen fibers in the dermis.According to the clinical manifestations and histopathological findings,the patient was diagnosed with ulerythema ophryogenes,and given oral vitamin A 2.5 million unit once a day,vitamin E 100 mg once a day,topical vitamine E cream twice a day,0.025％tretinoin ointment once at night.Two weeks later,the lesions improved.
