Objective:To investigate the expression of pre-B-cell leukemia homeobox 3 (PBX3) and the phosphatase and tensin homology deleted on chromosome 10 (PTEN) in cervical cancer and its relationship with the clinicopathologic characteristics and prognosis.Methods:Cervical cancer tissues and adjacent tissues of 85 patients with cervical cancer admitted to Xianlin Gulou Hospital from June 2014 to December 2018 were collected and the expression levels of PBX3 and PTEN were detected by immunohistochemistry. The univariate analysis and Logistic regression model were used to analyze the relationship between the expression levels of PBX3, PTEN and clinicopathologic features. Kaplan-Meier survival curve was used to analyze the relationship between the expression levels of PBX3, PTEN and prognosis.Results:The positive expression rate of PBX3 protein in cervical cancer tissues was higher than that in adjacent tissues: 38.82%(33/85) vs. 25.53%(20/85); the positive expression rate of PTEN protein was lower than that in adjacent tissues: 36.47%(31/85) vs. 98.82%(84/85), and there were significant differences ( P<0.05). The univariate analysis showed that the expression levels of PBX3 and PTEN were associated with clinical stages, degree of tumor differentiation, lymph node metastasis, vascular invasion, and degree of tumor invasion ( P<0.05). The multiple Logistic regression model showed that the clinical stages, tumor differentiation and lymph node metastasis were independent influencing factors for the positive expression of PBX3 or PTEN in cervical cancer tissues ( P<0.05). While 45.45%(15/33) of patients with positive PBX3 expression died, with a median survival of 31 months, and 25.00% (13/52)of patients with negative expression died, with a median survival of 38 months. Kaplan-rank test showed that the survival time in the patients with positive PBX3 expression and in the patients with negative expression had significant difference ( P=0.025). While 22.58%(7/31) of patients with positive PTEN expression died, with a median survival of 39 months, and 38.89%(21/54) of the patients with negative expression died, with a median survival time of 33 months. Kaplan-rank test showed that the survival time in the patients with positive PTEN expression and in the patients with negative expression had significant difference ( P=0.035). Conclusions:The expression of PBX3 is up-regulated and PTEN is down-regulated in cervical cancer. The expression levels of PBX3 and PTEN are related to clinical stage, tumor differentiation and lymph node metastasis. The prognosis of the patients with positive PBX3 expression is worse than that of the patients with negative expression, and the prognosis of the patients with positive PTEN expression is better than that of the patients with negative expression.

Objective To explore the roles of insulin in the early treatment of acute brain injury and its administration methods.Methods 253 patients were randomly divided into the intensive insulin therapy group and the conventional therapy group.Infection rates,the short-term effect (APACHE Ⅱ assessment),and long-term efficacy (GOS prognosis) was compared between two groups.Results The results of the strengthen treatment group in the rate of infection (25.95％ vs 39.34％,x2 =5.17,P ＜0.05),the short-term effect (11.33 ± 7.66 vs 16.49 ± 14.97,u =3.42,P ＜ 0.05) and the long-term efficacy (40.46％,55.73％,3.82％ vs 25.41％,68.85％,5.74％,x2 =7.62,P ＜0.05) were significantly better than the conventional therapy group with the statistically significant differences (P ＜ 0.05).Conclusions The hypoglycemic effect,neuroprotective effect,regulatory role,and nutrition role of insulin occurred in the early treatment of acute brain injury.After acute brain injury,patients with hyperglycemia should be treated early with an enough volume,continuous,and uniform insulin.

Objective:To investigate the curative effect and prognostic factors of primary liver cancer(PHC) treated with radical resection combined with transcatheter arterial chemoembolization (TACE).Methods:A retrospective analysis was used to analyze the clinical data of 136 cases of PHC patients treated in Qianjiang Central Hospital of Hubei Province from January 2008 to January 2012,the 86 cases received radical resection and postoperative adjuvant TACE treatment of patients as the observation group,and the remaining 50 cases only with radical resection in the treatment of patients were selected as control group.After 6 months of treatment,the level of tumor markers Carcinoembryonic antigen(CEA),alpha fetoprotein(AFP),CA199 and alanine aminotransferase(ALT) in two groups were observed and compared.The survival status and prognostic factors of the two groups were compared.Results:After 6 months of treatment,the leve of tumor markers CEA,AFP,CA199 and ALT in the observation group were significantly lower than those in the control group(P＜0.05);The 1-year,2-year,and 3-year survival rate of the observation group were significantly higher than those in the control group;Univariate analysis showed that the differentiation degree,tumor size,lymph node metastasis,vascular tumor thrombus,CA199 concentration factors and the observation group patients (radical resection and postoperative adjuvant TACE) postoperative survival period (P＜0.05);Further multivariate analysis showed that the degree of differentiation,lymph node metastasis and CA199 concentration were the important factors influencing the prognosis of patients with TACE after radical resection (P＜0.05).Conclusion:Radical resection combined with TACE in the treatment of PHC has well clinical curative effect,which can effectively improve the postoperative long-term survival rate.Degree of differentiation,lymph node metastasis,and CA199 concentration are important factors impacting the radical resection operation adjuvant TACE prognosis.

Objective To evaluate the effect of preadministration phenylephrine on the hemodynamics result from oxytocin during caesarean section.Methods One hundred parturients,ASA Ⅰ-Ⅱ,with single baby at full term in vertex presentation scheduled for cesarean section under continuous epidural anesthesia were randomly divided into 4 groups,each group was 25 cases.All parturients received injection 10 U of oxytocin in the uterus after delivery,followed by an oxytocin rapid infusion of 10 U (less than 5 min),meanwhile,through the other intravenous channel,injection of phenylephrine 1 μ g/kg in group 1,2 μ g/kg in group Ⅱ,3 μ g/kg in group Ⅲ,while injection of 0.9％ sodium chloride 1 ml in groupⅣ as control.The mean arterial pressure (MAP) and heat rate (HR) at preanesthesia (T0),the time of oxytocin injection after dehvery (T1) and after oxytocin injection 30 s (T2),1 ain (T3),3 min (T4),5 ain (T5),10 min(T6) was recorded.Results There were no significant difference in MAP at T0 and clinical data among the groups (P ＞ 0.05).The level of MAP in group Ⅰ and Ⅳ at T3-T5 was significantly lower than that at T0[(82 ± 7),(79 +5),(83 ± 6) mm Hg(1 mm Hg =0.133 kPa) vs.(90 ± 7) mm Hg,(84 ±7),(76 ± 5),(82 ±7) mm Hg vs.(91 ±7) mm Hg] (P ＜0.05).The level of MAP in group Ⅲ at T2-T3 was significantly higher than that at T0[(93 ± 8),(103 ± 10)mm Hg vs.(91 ± 8) mm Hg] (P ＜ 0.05).Compared with group Ⅳ,the level of MAP in group Ⅱ at T3-T5 was significantly higher,the level of MAP in group Ⅲ at T2-T5 was significantly higher,there was significant difference (P ＜0.05).The level of HR had no significant difference in T0 among the groups (P ＞ 0.05).The level of HR in four groups at T3-T5 was significantly higher than that at T0[(98 + 12),(105 + 12),(96 + 9) times/ain vs.(79 ± 8) times/ain,(89 ± 10),(96 ± 13),(92 + 12) times/min vs.(80 ± 11) times/min,(88 ± 10),(94 ± 12),(90 ± 9) times/min vs.(83 ± 10) times/min,(94 ± 12),(112 ± 13),(102 ± 1 1) times/ain vs.(82 ± 9) times/min](P ＜ 0.05 or ＜ 0.01),and reached to peak value at T4(P＜ 0.01),then gradually declined to the baseline values (T1) except in group Ⅳ at T6.Compared with group Ⅳ,the level of HR in group Ⅲ and group Ⅲ was significantly decreased at T4-T5(P ＜ 0.05).The rate of MAP decrease range above 30％ in group Ⅳ was 24％(6/24),and significantly higher than that in group Ⅱ (0) and group Ⅲ (0),there was significant difference(P＜ 0.05).The rate of nausea in group Ⅳ was significantly higher than that in group Ⅱ and group Ⅲ,there was significant difference (P ＜0.05).The scores of Apgar scale after delivery 1,5 min had no significant difference among four groups (P ＞0.05).Conclusion Haemodynamic stability can be obtained by administration 2 μ g/kg of phenylephrine when parturients received injection 10 U of oxytocin in the uterus after delivery,and followed by an oxytocin rapid infusion of 10 U during cesarean section.

Objective To evaluate the efficacy and safety of permissive hypercapnia ventilation in mechanically ventilated newborns.Methods PubMed,Embase,the Cochrane Library,China National Knowledge Infrastructure (CKNI),Wanfang Data and Chinese BioMedical Literature Database (CBM) were searched up until March 31,2013.Randomized controlled trials (RCTs) comparing permissive hypercapnia (PHC) group with normocapnia (NC) group in mechanically ventilated newborns were included.The primary outcomes included the incidence of ventilator associated lung injury (VALI),bronchopulmonary dysplasia (BPD),intraventricular hemorrhage (IVH),periventricular leukomalacia (PVL),patent ductus arteriosus (PDA),neonatal necrotizing enterocolitis (NEC),neurodevelopmental injury and the mortality rate.Secondary outcomes included the duration of ventilatory support and the length of hospital stay.The Cochrane Handbook 5.1.0 was used to evaluate the methodological quality and RevMan 5.1 software from Cochrane Collaboration was used for meta-analysis.The fixed effects model or the random effects model was adopted according to the result of heterogeneity.Results (1) A total of 325 articles were searched,and eight RCTs involving 605 newborns (302 newborns in PHC group while 300 newborns in NC group) which met the inclusion criteria were selected.In seven studies,the partial pressure of carbon dioxide (PCO2) was controlled at ＜ 65 mmHg (1 mmHg=0.133 kPa) and pH at ≥ 7.2 in PHC group.In one study,PCO2 was ＞ 52 mmHg and pH＞7.2,without descripition of the upper limit of PCO2.(2) Four articles described the method of random allocation in detail; three described allocation concealment; all eight studies used blinding method for research subjects; two used blinding method for outcome assessment; all eight studies reported complete data; and three articles described the source of other bias.(3) All eight studies reported the incidence of VALI (I2=56％,P=0.03).The random effects model was used for the meta-analysis,and there was significant difference between PHC group and NC group (RR=0.52,95％CI:0.29-0.93,P=0.03).According to the gestational age,the eight studies were divided into two subgroups.One subgroup,including three studies with an average gestational age of 25 weeks (I2=0％,P=0.46),showed no significant difference in the incidence of VALI between PHC and NC group (RR=1.05,95％CI:0.72-1.54,P=0.78).The other subgroup,including five studies with gestational age of ＞27 weeks (I2=0％,P=0.68),showed significant difference in the incidence of VALI between the two groups (RR=0.27,95％CI:0.14-0.50,P＜0.01).The in-hospital mortality and duration of ventilation showed significant difference between the two groups (in-hospital mortality:RR=0.40,95％CI:0.22-0.74,P＜0.01; duration of ventilation:difference in means=-0.75,95％CI:-1.04--0.46,P＜0.01).There was no significant difference in the incidence of BPD,IVH,PVL,PDA,NEC and neurodevelopmental impairment between the two groups (all P＞0.05).Conclusions PHC ventilation in mechanically ventilated newborns can decrease the incidence of VALI,the in-hospital mortality and the duration of ventilation,while its protective efficacy against BPD is not remarkable.It does not increase the risk of IVH,PVL,PDA,NEC and neurodevelopmental injury,when the PCO2 is ＜ 65 mmHg and pH ≥ 7.2.

This review focuses on the fetal origins of adult disease hypothesis put forward by David Barker and his colleagues,recent advances in epidemiological studies and experimental research in this field.Barker Hypothesis states that environmental factors,particularly intrauterine nutrition,as indicated by birth weight,operate in early life to program the risks for adverse health outcomes in adult life.A large growing body of reports described the association between the early development and adult diseases,such as diabetes,hypertension,coronary heart disease,abnormal lipids metabolism,obesity and cancer,etc.Experimental studies show that the changes of some key genes' expression,caused by epigenetic modifications,lead to a permanent alteration of cellular proliferation and differentiation and finally the genesis in key tissues and organs.These results bring about the impairment in structures and functions and the increased susceptibility to chronic diseases in adult life.The hypothesis provides a new perspective for the prevention and therapy of chronic diseases.

Objective To study the anti-aging effect of caloric restriction in aged rats. Method Thirty-four male aged SD rats were randomly divided into 3 groups. The experimental groups were given 80% and 60% diet of the control respectively. After 6 months we measured serum SOD,MDA,IL-2,the activity of NO,MAO in brain tissue and apoptosis index of hepatocytes. Results The activities of NO in brain tissue,SOD and IL-2 in serum in experimental groups were significantly higher than those in control group. Serum MDA,MAO of brain tissue and apoptosis index of hepatocytes in experimental groups were lower than those in control. Conclusion Caloric restriction shows anti-aging biological effects in aged rats.

Objective To evaluate the clinical application of helical CT 3D reconstruction technique in the dental orthopaedics. Methods The helical CT was performed with 3.0 mm slice thickness and 1.0 pitch in 41 patients with dental orthopaedics. The 3D reconstructions, including maximum intensity projection (MIP), surface shaded display (SSD), and multiplanar reconstructions (MPR), were made for all the cases. Results Thirty-seven of the 41 patients showed malalignment, tilt, rotation, overlap of the teeth and the different space between the longitudinal axes of the teeth. Twenty-five cases of them have shown 36 buried teeth in all. The axial images covered all the information. SSD demonstrated the external contours and entire morphologies of the teeth and the mandible with the relationship of the teeth alignment and the mandible. MIP clearly manifested the full view and the longitudinal alignment of the teeth. Among the 36 buried teeth, there were 29 palatally and 7 labially presented teeth, and they were morphologically delineated on MIP through various angles. Conclusion The helical CT 3D reconstruction is a new technique to display the stereoscopic configuration of teeth. The combination of axial images and MIP, SSD, and MPR provides valuable anatomic and diagnostic information helpful for the surgeons to structure and determine the treatment protocol for the dental orthopaedics.
