Objective To explore the changes of serum interleukin-6 (IL-6),and interleukin-8 (IL-8) in patients with gastric cancers and the clinical relationships with Helicobacter pylori (Hp) infection.Methods Totally 62 cases of patients who were diagnosed gastric cancer in our hospital from January 2013 to September 2015 were selected as the study group,who did not accept anti-tumor therapy.The patients were divided into the Hp positive group (with 53 cases) and Hp negative group (with 9 cases) according to whether the merger of Hp infection.Another 60 normal healthy volunteers of the same age in our hospital for health examination during the same period were selected as the control group.The serum IL-6 and IL-8 levels were detected,and the changes of the factors in the study group and control group were compared and analyzed,as well as the U values of Hp infection.The clinical relationships between the expression levels of the two in patients with gastric cancer and the U values of Hp infection were confirmed.Results The serum IL-6 and IL-8 levels and the U values of Hp infection of the study group were significantly higher than those of the control group (P ＜ 0.05),which in the Hp positive group were significantly higher than those in the Hp negative group (P ＜ 0.05).The levels of serum IL-6 and IL-8 in patients with gastric cancer showed positive correlations with the U value of Hp infection (r =0.457,0.531,P ＜ 0.05).Conclusions The serum IL-6 and IL-8 levels in patients with gastric cancer are much higher than those in normal healthy people,and there are significant positive relationship with Hp infection.It can improve the curative effect of gastric cancer patients by improving the eradication rate of Hp.

Objective:To study the therapeutic effect of bone peptide combined with rifapentin and levofloxacin on bone and joint damage caused by brucellosis.Methods:A prospective study was conducted to select 64 patients with brucellosis bone and joint damage admitted to Shanxi Provincial People's Hospital from January 2017 to June 2021. They were randomly divided into a control group (32 cases) and an observation group (32 cases) using a random number table method. The control group was treated with rifapentin and levofloxacin, while the observation group was treated with bone peptide on the basis of the control group, with a treatment period of 8 weeks, and the peripheral venous blood sample was collected before and after treatment. The visual analogue scale (VAS), activity of daily living (ADL) score, serum C-reactive protein (CRP), procalcitonin (PCT), erythrocyte sedimentation rate (ESR), and cytokines [tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6)] levels were compared before and after treatment.Results:The total effective rates of treatment in the observation group and the control group were 90.62% (29/32) and 65.62% (21/32), respectively, with statistically significant differences between the groups (χ 2 = 5.85, P = 0.016). After treatment, the VAS score of the observation group was lower than that of the control group ( t = 8.29, P < 0.001), and the ADL score was higher than that of the control group ( t = 6.77, P < 0.001). Both groups had lower VAS scores after treatment than before treatment in the same group ( t = 21.72, 15.09, P < 0.001), and higher ADL scores than before treatment in the same group ( t = 22.49, 12.54, P < 0.001). After treatment, the levels of CRP, PCT, ESR, TNF-α, and IL-6 of the observation group were lower than those of the control group ( t = 8.11, 10.75, 4.64, 5.11, 4.55, P < 0.001); the levels of CRP, PCT, ESR, TNF-α, and IL-6 in the two group were lower than these before treatment in the same group ( t = 14.21, 21.47, 11.21, 15.07, 9.73, 15.50, 21.30, 7.52, 6.78, 4.93, P < 0.001). Conclusion:The bone peptide combinated with rifapentin and levofloxacin has a good therapeutic effect on bone and joint damage caused by brucellosis, which can significantly reduce pain and cellular inflammatory reactions in patients, and improve their quality of life.

OBJECTIVETo study the injection of NKG5SV gene to inhibit growth and metastasis of hepatocellular carcinoma (HCC).

METHODSNKG5SV gene was inserted into retroviral vector pLXSN by normal methods. LacZ gene was used as control. LCI-D20 tumor together with saline, pLXSN-LacZ DNA or pLXSN-NKG5SV was subcutaneously inoculated to the nude mice. Tumor formation rate and tumor size were noted 35 days after inoculation. LCI-D20 tumor was inoculated subcutaneously. Saline, pLXSN-LacZ DNA or pLXSN-NKG5SV was intratumorally injected respectively 10 days after inoculation. Tumor growth was observed 35 days after inoculation. Liver cancer was resected 22 days after intrahepatic inoculation. Saline, pLXSN-LacZ DNA or pLXSN-NKG5SV was respectively injected at incisal margin or intraspleen. Mice were killed 35 days after inoculation to observe tumor recurrence at incisal margin, intrahepatic metastasis and extrahepatic metastasis.

RESULTSTumor formation rate and tumor diameter(cm) were 1.76 +/- 0.11, 1.51 +/- 0.34, 0.33 +/- 0.04 in the control group, LacZ group, NKG5SV group respectively when tumor and different cDNA were inoculated together. Tumor diameter(cm) and weight(g) were 0.87 +/- 0.08, 0.83 +/- 0.05, 0.26 +/- 0.04; 0.43 +/- 0.06, 0.38 +/- 0.04, 0.08 +/- 0.06 in the control group, LacZ group, NKG5SV group respectively when different cDNA were injected into the LCI-D20 tumor. Sites with extrahepatic metastasis nidi, incisal margin recurrence tumor size(cm), intrahepatic metastasis nidi, metastasis involved hepatic lobes in the control group, LacZ group, NKG5SV group were 4.25 +/- 1.48, 4.25 +/- 1.04, 0.63 +/- 0.51; 1.51 +/- 0.27, 1.35 +/- 0.17, 0.81 +/- 0.17; 2.50 +/- 1.41, 2.38 +/- 1.06, 1.25 +/- 0.71; 2.13 +/- 0.99, 2.00 +/- 0.75, 1.38 +/- 0.74 respectively when NK cells were injected at incise margin.

Objective To assess the application effect of reminder software for the management of indwelling catheter in catheter associated with urinary tract infection in emergency intensive care unit (EICU). Methods We conducted a comparative study among patients with catheter-associated urinary tract infection from January 2014 to December 2015 in emergency intensive care unit (EICU). By applying with reminder software, we assessed the omission rate of indwelling urethral catheterization management, the incidence rate of catheter associated urinary tract infection (CAUTI), the utilization rate of urinary tract intubation and the average time of indwelling urethral catheterization.Results By the application of reminder software, the omission rate of indwelling urethral catheterization management was decreased. The incidence rate of CAUTI declined from 9.16‰ to 1.90‰ (x2=4.843,P<0.05),while the utilization rate of urinary tract intubation declined from 73.60% to 60.67% (P<0.01), and the average time of catheterization also shortened from (10.21±2.28) days to (8.20±1.67) days (t=2.47,P<0.05).Conclusions Reminder software applied in the control of indwelling catheter related infections has achieved good effectiveness and it can be used widely in clinical work.

Objective:To analyze risk factors for deep vein thrombosis(DVT)in patients with severe cerebral infarction and to find early and sensitive indicators for the prediction and intervention of DVT.Methods:A total of 226 patients with severe cerebral infarction aged 62.5±12.9 years in our department from January 2017 to May 2020 were enrolled.Clinical data, biochemical examinations and color Doppler ultrasound results were collected.Risk factors for DVT were analyzed.The receiver operating characteristic curve(ROC)was used to determine the cut-off value, area under the curve, sensitivity and specificity.Results:Age, reaction(R)time of blood coagulation factors on thromboelastography(TEG)and fibrinogen degradation products(FDP)were risk factors for DVT with no adjustment of the overall effect of time on coagulation mechanisms.According to time stratified analysis, decreased R time( OR=0.58, 95% CI: 0.40-0.84)and increased FDP( OR=1.17, 95% CI: 1.02-1.33)within 3 days of onset were risk factors for DVT, and the cut-off values were 5.35 min and 0.39 mg/L, respectively; 3 and 7 days after onset, increased D-dimer was a risk factor for DVT( OR=2.73, 95% CI: 1.53-4.86; OR=2.57, 95% CI: 1.32-5.03), and the cut-off values were 0.39 mg/L and 0.76 mg/L, respectively.Excluding the effects of FDP primary and D-Dimer secondary fibrinolysis, risk factors for DVT within 3 days of onset were decreased R time on TEG and increased age, and all risk factors were not statistically significant 3 days and 7 days after onset( P<0.05). Conclusions:The key factors affecting DVT in patients with severe cerebral infarction are different at different stages.Decreased R time within 3 days of onset is a predictive indicator of DVT.FDP and D-dimer can be used to assess thrombosis, but may not be appropriate as predictive indicators.

Objective:To analyze the factors related to the duration of chest compression pause time during the manual-mechanical conversion process in cardiopulmonary resuscitation (CRP).Methods:A retrospective study was devised in a cohort comprising patients with out-of-hospital cardiac arrest, who were assigned to receive mechanical CRP in the Department of Emergency of Huzhou First People's Hospital from January 2019 to December 2020. Patient’s general characteristics, CRP data and data on CRP-free intervals were collected multiple linear regression to analyze associations with the duration of chest compression pause time during the manual-mechanical conversion process in CRP. At the same time, the effect of CPR treatment qualification of nurses on CPR compression quality was evaluated.Results:The study selected 32 eligible patients. Patient's height, actual body weight, and body mass index showed a positive liner correlation with the duration of chest compression pause time ( r=0.61, 0.92, 0.49; P<0.01). Multiple stepwise regression analysis showed that actual body weight was an independent risk factor for prolonged duration of chest compression pause time ( P<0.01). Moreover, responsible nurses with advanced cardiac life support (ACLS) certification had significantly higher compression scores than those without ACLS certification (χ 2=0.002, P<0.01). Conclusions:The actual body weight of patients and the ACLS qualification of nurses on duty have a certain relationship with the duration of chest compression pause time during the manual-mechanical conversion process in CRP, which is worthy of further research.
