Objective To investigate the effects of β-blockers on cardiac protection and hemodynamic in patients with septic shock. Methods A prospective randomized controlled trial was conducted. Forty-one patients with septic shock in accordance with early goal directed treatment and met the target within 6 hours,and admitted to intensive care unit (ICU)of Affiliated Huxi Hospital of Jining Medical College from January 2012 to January 2014 were enrolled. The patients were divided into treatment group (n=21)and control group (n=20)by random number table. The patients in both groups were given the standard treatment,esmolol was giving to patients in treatment group in order to control the heart rate (HR)below 100 bpm within 2 hours,and the patients in control group only received standard treatment. The changes in hemodynamic parameters〔mean arterial pressure(MAP),central venous pressure(CVP), HR,cardiac index(CI),stroke volume index(SVI),systemic vascular resistance(SVRI),global end diastolic volume index(GEDVI)〕,biochemistry metabolic of tissue〔central venous oxygen saturation(ScvO2),lactic acid(Lac)〕,and cardiac markers 〔troponin I (cTnI)〕before and 12,24,48,72 hours after the treatment were recorded. Results①Before treatment,the hemodynamic parameters,tissue metabolism index and cTnI had no significant differences in both groups (all P>0.05).②The hemodynamic parameters after treatment in the control group showed no significant difference compared with that before treatment. HR and CI in the treatment group were gradually declined after treatment,SVRI and GEDVI were gradually increased. There were significant differences in HR,CI,SVRI,and GEDVI between treatment group and control group from 12 hours on〔HR(bpm):93±4 vs. 118±13,CI (L·min-1·m-2):3.3 ±0.8 vs. 4.5 ±0.6,SVRI (kPa·s·L-1·m-2):159.2 ±27.4 vs. 130.5 ±24.2,GEDVI(mL/m2):668 ±148 vs. 588 ±103,P<0.05 or P<0.01〕. MAP,CVP and SVI in the treatment group showed no significant changes. ③Lac after treatment in both groups was decreased slowly,Lac (mmol/L)at 12 hours after treatment was significantly decreased compared with that before treatment (control group:8.8 ±3.2 vs. 9.8 ±3.4,treatment group:9.5±3.1 vs. 10.5±4.1,both P<0.05). The Lac of control group and treatment group were 2.5±1.2 and 2.7±1.1 at 72 hours after treatment,and there was no significant difference between two groups (all P>0.05). The ScvO2 was not decreased in both groups.④Compared with before treatment,cTnI in the control group was gradually increased,peaked at 72 hours,and that in the treatment group was gradually increased,peaked at 24 hours and then gradually declined. Compared with control group,the cTnI (μg/L)in the treatment group was decreased significantly at 24,48,72 hours (1.15 ±0.57 vs. 1.74 ±0.77,0.93 ±0.52 vs. 2.15 ±1.23,0.52 ±0.36 vs. 2.39 ±1.17,all P<0.01). Conclusionsβ-blockers (esmolol) can improve cardiac function and myocardial compliance,reduce the myocardial injury in patients with sepsis shock. Although β-blockers can decrease cardiac output,it has no influence on the circulation function and tissue perfusion.

Objective To explore the clinical value of transnasal high volume oxygen therapy in the treatment of patients with acute heart failure.Methods From January 2016 to January 2018,61 cases with acute heart failure in Huxi Hospital Affiliated to Jining Medical College were selected.The patients were randomly divided into control group and treatment group according to the digital table,31 cases in the control group and 30 cases in the treatment group.The two groups were routinely given control of fluid volume,analgesia,strong heart,diuresis,vasodilator,anti-platelet aggregation,camp support and so on.The control group was given conventional oxygen therapy,and the treatment group was treated with high flow oxygen through nose.Before treatment and 12h,24h,48h,72h after treatment,the left ventricular ejection fraction (LVEF),oxygen index (PaO2/FiO2),serum lactic acid (Lac),B type sodium and titanium (BNP) in serum,and the application rate of non-invasive mechanical ventilation and invasive mechanical ventilation in 7d were observed in the two groups.Results Compared with the control group,the LVEF of the treatment group in each time point increased [(35.58 ± 3.64) ％ vs.(37.77 ± 3.76) ％,(37.87 ± 3.58) ％ vs.(40.07 ±3.36)％,(44.94 ±3.19)％ vs.(46.83 ±3.21)％,(47.55 ±3.45％)％ vs.(40.07 ±3.36％)％,t =-2.308,-2.466,-2.316,-2.487,all P ＜ 0.05].The PaO2/FiO2 of the treatment group increased significantly at each time point after treatment [(177.39 ± 10.62) mmHg vs.(184.17 ± 10.49) mmHg,(188.00 ± 11.72) mmHg vs.(198.57 ± 18.47) mmHg,(204.06 ± 17.69) mmHg vs.(221.40 ± 23.80) mmHg,(265.23 ± 34.51) mmHg vs.(290.37 ± 26.72) mmHg,t =-2.507,-2.678,-3.236,-3.174,all P ＜ 0.05].The BNP level of the treatment group decreased significantly at each time point after treatment [(2 462.90 ± 288.00) ng/mL vs.(2 264.53 ± 366.44) ng/mL,(1 646.61 ± 377.19) ng/mL vs.(1 474.07 ± 214.03) ng/mL,(991.94 ± 242.95) ng/mL vs.(811.90 ±258.67) ng/mL,(653.77 ± 147.671) ng/mL vs.(526.47 ± 127.87) ng/mL,t =2.355,2.187,2.803,3.594,all P ＜ 0.05].The Lac level of the treatment group decreased significantly at 12h and 24h after treatment [(5.05 ± 0.69) mmol/L vs.(4.55 ± 0.80) mmol/L,(3.68 ± 0.89) mmol/L vs.(3.13 ± 0.77) mmol/L,t =2.610,2.601,all P ＜ 0.05],but there were no statistically significant differences between the two groups at 48h and 72h after treatment [(1.62 ± 0.65) mmol/L vs.(1.53 ± 0.65) mmol/L,(1.36 ± 0.64) mmol/L vs.(1.26 ± 0.46) mmol/L,all P ＞ 0.05].In the control group and the treatment group,the incidence rates of non-invasive mechanical ventilation in 7d were 35.48％ (11/31),13.33％ (4/30),respetively,the difference was statistically significant (x2 =4.034,P ＜ 0.05).In the control group and the treatment group,the incidence rates of invasive mechanical ventilation in 7d were 12.90％ (4/31),3.33％ (1/30),respetively,the difference was statistically significant (x2 =4.957,P ＜ 0.05).Conclusion Nasal high flow oxygen therapy has better clinical effect on patients with acute heart failure.It is a more active treatment measure,and is worthy of clinical application.

Objective To observe the effects of Fuyanshu Capsule on phenol mucilage-induced endometritis rats and the possible anti-inflammation mechanism of the therapeutic effects.Methods Chronic endometritis in rats was induced by injection of phenol mucilage suspension into the uterus.Sixty female SD rats were randomly divided into 6 groups,namely,sham-operation group (distilled water,10mL/kg),model group,Jinji capsule group (0.65 g/kg),and Fuyanshu Capsule groups (1.8 g/kg,0.9 g/kg and 0.45 g/kg).After the rats were treated 28 days with corresponding medicine by intragastric administration,the pathology of the endometrium and changes of tumor necrosis factor α(TNF-α)and interleukin-2 (IL-2)levels were detected to evaluate the effects of Fuyanshu Capsule. Results Fuyanshu Capsule (1.8 g/kg and 0.9 g/kg)ameliorated the body weight reduction caused by endometritis in rats.Fuyanshu Capsule (1.8 g/kg,0.9 g/kg and 0.45 g/kg)reduced the ratio of the swelling uterus and ovaries to body weight of the rats.It ameliorated obviously the hyperplasia,necrosis and degeneration of endometrial epithelia and infiltration of inflammatory cells.The capsule (1.8 g/kg)decreased the serum IL-2 level in the rats with phenol mucilage-induced endometritis. Conclusion The anti-inflammatory effect of Fuyanshu Capsule on chronic endometritis induced by phenol mucilage in rats may be related to the decrease of IL-2 level.

Objective To understand the status of water contact and labor practice of residents in plateau mountain schisto?somiasis endemic areas in Yunnan Province so as to provide the evidence for formulating the strategy of prevention and control of schistosomiasis in the next step of work. Methods A total of 412 residents aged 6-65 years old in 2 villages were randomly sampled and investigated with questionnaires for their water contacts and labor practices in plateau valley schistosomiasis endem?ic areas. Then the schistosome infection status of the residents was surveyed with the indirect hemagglutination assay IHA . Re?sults Among the 412 residents investigated the rate of water contact was 88.35% and the main causes of water contact were watering and swimming and playing. The percentages of residents who had schistosomiasis history were 1.16% 0.00%30.80% 3.85% and 0 in them who had swimming and playing water?contacts bathing watering washing hands and others respectively χ2=38.96 P<0.01 . The positives of IHA in the above?mentioned residents were 18.60% 0.00% 37.60%23.08% and 0 respectively χ2=12.61 P<0.05 . Conclusions The productive infested water contact is the main way of schistosome infection. Therefore the changes of labor practices and water contact of the residents are very important for the ef?fective prevention and control of schistosomiasis transmission.

Objective To evaluate the effect of comprehensive schistosomiasis control measures based on infection source control in plateau mountain areas of Yunnan Province. Methods From 2006 to 2004,four administrative villages were selected as test areas from plateau canyon and plateau basin endemic areas in Jindun Town,Heqing County,two villages each type,and the comprehensive control measures were implemented,including the examination and treatment of schistosomiasis,Oncomela?nia hupensis snail survey and control,health education,improving drinking water and lavatories,banning grazing,constructing sanitary pen of livestock,replacing cattle with machine,etc. The schistosome infection state and snail status in 2006 were treat?ed as the baseline information,and the effect of the comprehensive measures were evaluated. Results The infection rate of hu?man in plateau canyon areas decreased from 4.94%in 2006 to 0.06%in 2014,and that of livestock decreased from 1.11%to 0. In plateau basin areas,there was only 1 case of schistosomiasis found in Xiaolian Village in 2007,and no any other cases found in the other years,the infection rates of livestock dropped from 7.38%to 0. Compared with 2006,the snail areas in the two type areas decreased by 74.89%and 75.30%,respectively,meanwhile,the percentage of snail area,the occurrence rate of frames with snails,as well as the average density of living snails also decreased,and no infected snails were found since 2008. Xidian and Xinzhuang villages in plateau canyon area reached the criteria of schistosomiasis transmission controlled in 2009,and Xiao?lian and Kangfu villages in plateau basin reached the criteria of transmission interrupted in 2014. Conclusions The comprehen?sive schistosomiasis control measures based on infection source control can effectively control the endemic situation of schistoso? miasis in plateau areas of Yunnan Province. In the future,we should pay an equal attention to the infection sources control and snail control to consolidate and amplify the achievement of schistosomiasis control.

Objective To investigate the effect of early mobilization on diaphragmatic function in patients with mechanical ventilation (MV). Methods Sixty chronic obstructive pulmonary disease with acute exacerbation (AECOPD) patients with respiratory failure (RF) and underwent MV admitted to intensive care unit (ICU) of Huxi Affiliated Hospital of Jining Medical College from January 2016 to January 2017 were enrolled. The patients were divided into treatment group (n = 30) and control group (n = 30) by randomly number table method. The two groups were given analgesia, sedation, MV, antibiotics, nutritional support and other treatments. An implementation plan was developed based on the clinical practice of pain, irritability and delirium in adult patients (PAD) with ICU, while the treatment group was given early mobilization (such as joint activity, stand to the bed, 3 times a day). The diaphragmatic thickness at the end of expiration (DTee), diaphragmatic thickness at the end of inspiration (DTei) and diaphragmatic thickening fraction (DTF) were measured by bedside ultrasonography before and 24 hours, 48 hours, 3 days and 5 days after treatment respectively. Results There were no significant differences in the parameters of the diaphragm before treatment between the two groups. In the control group, DTee was gradually decreased at 5 days after treatment and was significantly lower than that before treatment (cm: 0.26±0.06 vs. 0.28±0.08, t = 3.045, 1 = 0.005). While there was no significant change in DTee in the treatment group. There was no significant difference in DTee between the two groups at different time points after treatment. DTei and DTF were significantly increased in the two groups after treatment, and reached the peak value at 48 hours; with the prolonged of MV time, DTei and DTF in the control group at 3 days and 5 days were significantly lower than those at 48 hours [DTei (cm): 0.35±0.07, 0.34±0.07 vs. 0.36±0.08; DTF: (29.29±11.01)%, (28.62±11.97)% vs. (32.48±15.63)%, all 1 < 0.01]; there were no significant changes in the treatment group. DTF in the treatment group at 3 days and 5 days was significantly higher than that in the control groups [(38.53±11.39)% vs. (29.29±11.01)%, (37.27±11.26)% vs. (28.62±11.97)%, both 1 < 0.01]. Conclusion MV can lead to diaphragmatic dysfunction, while early mobilization can delay diaphragmatic atrophy and systolic dysfunction in MV patients.

Objective To investigate the effect of early activities on risk factors of acute gastrointestinal injury (AGI) in patients with chronic obstructive pulmonary disease (COPD) induced by mechanical ventilation.Methods A total of 118 mechanically ventilated non-diabetic patients with chronic obstructive pulmonary disease who were admitted to our hospital from August 2017 to April 2018 were enrolled in the study.The patients were divided into AGI group (71 cases) and non-AGI group (47 cases) according to the presence or absence of AGI.The examined data were collected in the patients prospectively such as preprocalcitonin (PCT),D-lactic acid,serum albumin (ALB),fasting plasma glucose (FPG),fasting insulin (FINS),and Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) scores were calculated.The homeostasis model insulin resistance index was used (HOMA-IR) to assess the subjects' insulin resistance.Logistics regression analysis screened for risk factors that affected patients' AGI.The AGI patients were divided into treatment group (36 cases) and control group (35 cases) according to the random number table method.On the basis of the same conventional treatment,the treatment group were received early mobilization.The differences of PCT,D-lactate,FPG,HOMA-IR,APACHE Ⅱ scores,and AGI grades before and after treatment for 3 days were observed for both groups of patients.Results The PCT,D-lactate,FPG,HOMA-IR,and APACHE Ⅱ scores were higher in the AGI group than in the non-AGI group [(2.72 ±0.54)ng/ml vs (1.81 ±0.62)ng/ml;(17.43 ±2.63)mg/ml vs (13.61 ± 1.6)mg/ml;(10.1 ±l.0)mmol/L vs (8.4 ±0.9) mmol/L;(2.4 ±0.5) vs (1.7 ±0.4);(23.8 ±2.9) point vs (21.7 ±4.3)point],and the ALB were lower than non-AGl group [(29.1 ±2.2)g/L vs (30.6 ±3.2)g/L],with statistically significant difference (P ＜ 0.05).Multivariate logistic regression analysis showed that PCT,D-lactic acid,FPG,HOMA-IR,and APACHE Ⅱ scores were risk factors for AGI in mechanically ventilated non-diabetic patients with COPD (regression coefficients were 4.337,1.226,5.106,4.469,0.584 respectively,P ＜0.05).There were no significant difference in PCT,D-lactate,FPG,HOMA-IR,APACHE Ⅱ scores between the treatment group and the control group before treatment (P ＞ 0.05).The PCT,D-lactic acid,FPG,HOMA-IR,and APACHE Ⅱ scores in the treatment group were significantly lower than those in the control group after early treatment [(2.00 ± 0.49) ng/ml vs (2.34 ± 0.34) ng/ml;(15.38 ± 1.71)mg/ml vs (17.38 ±2.88)mg/ml;(8.9 ±0.9)mmol/L vs (9.6 ±0.7)mmol/L;(1.9 ± 0.4) vs (2.2 ± 0.4);(21.0 ± 1.8) point vs (22.2 ± 2.7) point],and AGI severity was reduced (There were 8,18,6,3 and 1 cases of 0,Ⅰ,Ⅱ,Ⅲ,and Ⅳ in the treatment group,and4,12,9,7 and 3 in the control group respectively),with statistically significant differences (P ＜ O.05).Conclusions PCT,Dlactic acid,FPG,HOMA-IR,and APACHE Ⅱ scores were risk factors for AGI in mechanically ventilated non-diabetic patients with COPD.Early mobilization could reduce the level of these risk factors and the severity of AGI.

Microglia differ from macrophages with unique origin and role. In glioblastoma, microglia plays an important role in regulating tumor immune status, promoting tumor angiogenesis, destroying the blood-brain barrier, and reducing the sensitivity of treatment. Therefore, the combination of microglial therapy in the radiotherapy, chemotherapy and immunotherapy of glioblastoma has also become a clinically promising treatment.
