Objective: To investigate the psychosocial characteristics and mind-physique status of pa-tients with gynecological malignant tumors. Methods: Clinical psycho-rating scale [life event scale (LES) and symptom checklist-90 (SCL-90)] was applied to test life events and mind-physique status of 60 cases of pa-tients with gynecological malignant tumor. The results were compared with those of 40 female patients with benign tumors and 40 normal females. Results: The frequency and tension value of total life events and those of negative life events in the malignant cancer group were much higher than those in the benign tumor group and normal group (P<0.05) and no remarkable differences were found in the frequency of positive life events among the three groups. The frequencies of total life events and negative life events were higher in the be-nign tumor group than those in the normal group (P<0.05) but there were no significant differences in the fre-quency of positive life events, total tension value or positive tension value among the three groups. No signifi-cant differences were found in the indices of SCL-90, positive scores and scorns of other factors among the three groups (P>0.05). The scores of somatization, obsession, interpersonal relationship sensitivity, anxiety, hostility, phobia, and paranoia were higher in the malignant tumor group than in the benign tumor group and normal group (P<0.05). The average positive scores and the depression scores in the benign tumor group were higher than those in the normal group (P<0.05), but there was no statistical significance in other indices between the benign tumor group and the normal group (P>0.05). Conclusion: Negative psychosocial factors are closely correlated with the occurrence and growth of gynecological malignant tumors. Active psychological intervention should be performed as eady as possible.

Objective To investigate the effect of soluble Tie2 fusion protein(sTie2/Fc)on the angiogenesis of peritoneal vessels in uremic peritoneal dialysis (PD) rats.Methods Rats were randomly divided into 6 groups:normal rats as control group (group1),rats with sham operation (group2),uremic rats without PD (group3),uremic rats dialyzed with 4:25％ PD solution (group4),uremic rats dialyzed with 4.25％ PD solution and treated by subcutaneous injection of 2.5 μg/kg sTie2/Fc (group5),uremic rats dialyzed with 4.25％ PD solution and treated by subcutaneous injection of 5.0 μg/kg sTie2/Fc (group6).sTie2/Fc was given every other day during peritoneal dialysis period,total 14 doses.After regular PD for 28 days,RT-PCR and tissue immunohistochemical staining were used to detect the mRNA and protein expressions of Angpt-2 in peritoneal tissues in each group of rats.Microvessel density (MVD) of peritoneum was detected and quantified with immunohistochemical staining by using anti-CD34 antibody.Results The expression of Angpt-2 mRNA and protein was found in each group.There was no significant difference of.Angpt-2 expression both in mRNA and protein level between group1 and group2.Compared with group1,the mRNA and protein expression of Angpt-2 were significantly increased in group3 and group4 (all P＜0.05).Compared with group3,the mRNA and protein expression of Angpt-2 were significantly increased in group4 (all P＜0.05).Compared with group 4,the mRNA and protein expression of Angpt-2 were significantly decreased in group5 and group6 (all P＜0.05).Compared with group5,the mRNA and protein expression of Angpt-2 were significantly decreased in group6 (all P＜0.05).Only few new microvessel was found in group1 and group2.Compared with group1,MVD was significantly up-regulated in group3 and group4 (all P＜0.05).Compared with group4,MVD was significantly down-regulated in group5 and group6 (all P＜0.05).Conclusions Peritoneum neoangiogensis can be effectively inhibited by sTie2/Fc in uremic rat treated with PD.Blocking of signal transduction may be involved in the mechanism of sTie2/Fc inhibiting peritoneal angiogenesis.

Objective To investigate the clinical value of cardiopulmonary resuscitation (CPR) with abdominal lifting and compression on patients with breathing and cardiac arrest induced by severe chest trauma.Methods Sixty-six breathing and cardiac arrest patients induced by severe chest trauma admitted to the General Hospital of Jingyuan Coal Industry Group Company from October 2011 to October 2016 were enrolled,and they were divided into abdominal lifting and compression group (n =32) and unarmed abdominal compression group (n =34) by random number table.The patients in both two groups were given the airway open,respiration support,defibrillation treatment,venous access establishment,vasoactive drugs application and other conventional treatments.On the basis of the routine treatment,the patients in abdominal lifting and compression group were given application of abdominal lifting and compression device with 100 times/min frequency and continuously alternating press down to lift the abdomen,the amplitude of pressing and pulling were 3-5 cm below or above the original level of the abdomen.Those in unarmed abdominal compression group were given abdominal CPR pressing method by hand,the frequency of pressing and depth of subsidence was the same as abdominal lifting and compression group.Heart rate (HR) and arterial blood gas at 30 minutes after CPR as well as the success rate of resuscitation were compared between the two groups.The changes in HR,mean arterial pressure (MAP) and pulse oxygen saturation (SpO2) before and 30 minutes and 60 minutes after CPR were dynamically observed in patients with restoration of spontaneous circulation (ROSC) after abdominal lifting and compression CPR treatment.Results Compared with the unarmed abdominal compression group,HR (bmp:136.13±6.14 vs.148.45±5.16) and arterial partial pressure of carbon dioxide [PaCO2 (mmHg,1 mmHg =0.133 kPa):48.51 ±2.60 vs.62.51 ±2.50] at 30 minutes after CPR in abdominal lifting and compression group were significantly lowered,and arterial partial pressure of oxygen (PaO2) was significantly increased (mmHg:88.07±3.92 vs.74.12±2.12,all P ＜ 0.05).Four patients with ROSC were found in abdominal lifting and compression group,and 2 in unarmed abdominal compression group.The success rate of resuscitation in abdominal lifting and compression group was significantly higher than that of unarmed abdominal compression group (12.50％ vs.5.82％,P ＜ 0.05).In 4 patients with ROSC after abdominal lifting and compression CPR showed a downward trend in HR and an upward trend in MAP and SpO2 with CPR time prolongation.Conclusions The effect of abdominal lifting and compression CPR is better than that of unarmed abdominal compression CPR,which is of great value for the life saving of patients with breathing and cardiac arrest induced bv severe chest trauma.

Objective To analyze the distribution of various genotypes of human cytomegalovirus glycoprotein N ( HCMV gN) in patients with HIV infection; to investigate the effects of HCMV-HIV co-in-fection on disease progression and the relationships between HCMV gN genotypes and disease progression. Methods Patients with active HCMV infection were screened out from 359 patients with HIV infection by using the pp65 antigenemia assay.The genes encoding HCMV gN ( UL73 ) were amplified by nested PCR ( nPCR) .The amplicons were digested by restriction enzymes including MboⅠ, ScaⅠ and SalⅠ.Then, the restricted fragment length polymorphisms were further analyzed on 4%agarose gel.The relationships be-tween HCMV genotypes and the morbidity and mortality of acquired immune deficiency syndrome ( AIDS ) were investigated via a prospective study.Results Among the 359 patients with HIV infection, 28 subjects were positive for the HCMV pp65 antigenemia assay.The HCMV gN genotypes in 20 patients with active HCMV infection were distributed as: gN-3a (4/20, 20%), gN-1 (4/20, 20%), gN-4d (1/20, 5%), gN-4b (1/20, 5%) and mixed infection (10/20, 50%).Patients with HCMV-HIV co-infection were more likely to develop AIDS during the follow-up period (RR=9.78).Patients harboring HCMV gN-1 and gN-4 genotypes would seem likely to have 4.6 times of chance leading to AIDS-associated death than those harbo-ring other HCMV gN genotypes.Conclusion HCMV infection ( especially gN-1 and gN-4 genotypes) might accelerate the progression of HIV infection.

Objective To investigate the effect of active abdominal compression-decompression cardiopulmonary resuscitation (AACD-CPR) in patients with pre-hospital respiratory and cardiac arrest.Methods Forty-five patients with respiratory and cardiac arrest,and with contraindication of chest compression admitted to Baiyin Central Hospital of Gansu Province from March 2012 to September 2018 were enrolled,and they were divided into two groups according to random number table.AACD-CPR (abdominal compression-decompression group,n =24) and cardiopulmonary resuscitation (CPR) with unarmed abdominal compression (unarmed abdominal pressure group,n =21) were performed respectively.The success rate of rescue was observed in the two groups,and the changes in heart rate (HR),pulse oxygen saturation (SpO2) and blood pressure 30 minutes after CPR in patients with restoration of spontaneous circulation (ROSC) were observed.Results Among the 24 patients in the abdominal compression-decompression group,5 patients (20.83％) had ROSC,and 2 patients (9.52％) had ROSC in 21 patients of the unarmed abdominal pressure group.The success rate of resuscitation in the abdominal compression-decompression group was significantly higher than that in the unarmed abdominal pressure group (P ＜ 0.05).HR of ROSC patients at 30 minutes of CPR in abdominal compression-decompression group was significantly lower than that in unarmed abdominal compression group (bpm:139.45±5.08 vs.147.62±5.24,P ＜ 0.05),and SpO2 and blood pressure were significantly higher than those in unarmed abdominal compression group with significant differences [SpO2:0.92 ± 0.03 vs.0.85 ± 0.03,systolic blood pressure (SBP,mmHg,1 mmHg =0.133 kPa):118.23 ± 3.26 vs.98.51 ± 3.10,diastolic blood pressure (DBP,mmHg):60.10 ± 2.50 vs.56.36 ± 2.45,all P ＜ 0.05].Conclusion The effect of AACD-CPR was superior to that of unarmed abdominal pressure CPR,which had higher application value to rescue patients with respiratory and cardiac arrest with chest pressure contraindication.

Objective:To explore the efficacy and safety of intermittent infusion of ilaprazole sodium and high-dose continuous infusion of esomeprazole sodium in preventing rebleeding in patients with peptic ulcer bleeding after successful endoscopic hemostasis.Methods:This is a multi-center, interval randomized, double-blind, double-dummy, parallel controlled study. From March 3rd to June 15th, 2021, 151 patients with high risk of peptic ulcer bleeding and successfully underwent endoscopic hemostasis from 33 hospitals including the First Affiliated Hospital of Zhejiang University School of Medicine were enrolled. Patients were interval randomly divided into the trial group (74 cases) and the control group (77 cases). Patients in the trial group received intermittent intravenous infusion of ilaprazole sodium once daily (20 mg administered as a 60 min intravenous infusion on day 1, and 10 mg administered as a 30 min intravenous infusion on day 2 and 3); patients in the control group received continuous intravenous infusion of esomeprazole sodium for 72 h (esomeprazole sodium 80 mg at first dose in half an hour, and 8 mg per hour continuous intravenous infusion for 71.5 h). After intravenous infusion treatment, patients of both groups were given oral ilaprazole enteric-coated tablets, 10 mg each time, once a day for 4 d. The rebleeding rate after 72 h and within 7 d after treatment and the proportion of patients who received endoscopic retreatment or surgery due to rebleeding within 72 h after treatment were analysised based on the full analysis set (72 cases in the trial group and 75 cases in the control group); and the incidence rate of adverse reactions was observed in the two groups based on the safety analysis set (74 cases in the trial group and 76 cases in the control group). Chi-square test or Fisher exact probability test was used for statistical analysis.Results:There was no rebleeding case in the trial group within 72 h and 1 case of rebleeding within 7 d (1.39%, 1/72). In the control group, there was 1 case of rebleeding (1.33%, 1/75) within 72 h and 4 cases of rebleeding (5.33%, 4/75) within 7 d. There was no significant difference in rebleeding rate either after 72 h or within 7 d after treatment between the two groups (both P>0.05). Within 72 h of treatment, no patients in both groups needed endoscopic or surgical retreatment due to rebleeding. Adverse reactions occurred in 5 cases (6.8%, 5/74) and 6 cases (7.9%, 6/76) in the trial group and control group, respectively, which recovered spontaneously without treatment. No serious adverse reactions occurred in both groups. Conclusion:In patients with high-risk peptic ulcer bleeding with successful endoscopic hemostasis, intermittent intravenous infusion of ilaprazole sodium has similar efficacy and safety as continuous high-dose intravenous infusion of esomeprazole sodium, but the dosage of intermitten regimen is less, the administration is more convenient, and it is worthy of clinical promotion.
