ABSTRACT
Objective To investigate the effect of Kuanxiong Lifei decoction on inflammatory factors in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) and turbid phlegm obstructing lung syndrome. Methods Two hundred patients with AECOPD and turbid phlegm obstructing lung syndrome diagnosed by traditional Chinese medicine (TCM) differentiation visiting four hospitals of Longhua Hospital Affiliated to Shanghai University of TCM, Shanghai Seventh People's Hospital, Punan Hospital of Shanghai Pudong New Area, Gongli Hospital of Shanghai Pudong New Area were selected from May 2017 to March 2018, and they were divided into a test group and a control group by a random number table, 100 cases per group. The patients in the two groups were treated with routine western medicine according to the guidelines, and in the test group, additionally Kuanxiong Lifei decoction (components: pinellia ternate 15 g, allium macrostemon 12 g, ephedra 9 g, trichosanthes 30 g, poria cocos 15 g, almond 12 g, lumbricus 12 g, citrus peels 12 g, peach kernel 12 g , roasted licorice 6 g) was used for 10 days, the decoction was uniformly made by Chinese Medicine Pharmacy of Longhua Hospital, 1 dose daily, 2 times a day orally taken, warm 200 mL each time, 0.5 hours before or after meal. The efficacy was evaluated after treatment for 10 days. The level changes of white blood cell count (WBC), neutrophils (N), C-reactive protein (CRP), interleukin-8 (IL-8), tumor necrosis factor-α (TNF-α) before and after treatment and the improvement of TCM syndrome scores and clinical efficacy were observed in two groups. Results After treatment, the levels of WBC, N, CRP, IL-8, TNF-α, TCM syndrome score of the patients in the two group were significantly decreased compared with those before treatment in the two groups (P < 0.05), and the above indexes in the test group were all significantly lower than those in the control group after treatment [WBC (×109/L): 6.58±1.41 vs.7.44±1.85, N: 0.58±0.08 vs. 0.64±0.08, CRP (mg/L): 7.3±1.8 vs. 9.6±1.7, IL-8 (ng/L): 23.5±6.2 vs. 27.8±9.8, TNF-α (ng/L): 9.45±2.18 vs. 10.25±1.67, TCM syndrome total score: 4.0 (3.0, 8.0) vs. 8.0 (5.0, 10.0), all P < 0.05]. The total effective rate of the test group was significantly higher than that of the control group [88% (88/100) vs. 84% (84/100), P < 0.05]. Conclusion Kuanxiong Lifei decoction can significantly reduce lung inflammatory factors, ameliorate overall symptoms and improve the prognosis of AECOPD patients with turbid phlegm obstructing lung syndrome.
ABSTRACT
Objective To investigate the impact of sputum suction under laryngoscope in stroke patients on the occurrence and prognosis of ischemic stroke-associated pneumonia (SAP).Methods A total of 127 cases with acute ischemic stroke (AIS) with Glasgow Coma Scale 6-12 scores,non-artificial airway and need for intensive care were enrolled.According to the suction practice,the cases were divided into laryngoscope euthyphoria group (practice group,PG,n =59),and conventional oral or nasal sputum suction group (control group,CG,n =68).The PG was perspectively studied,while the CG were analyzed retrospectively.All patients were cared with the Guidelines for the management of adult with hospitalacquired ventilator-associated and healthcare-associated pneumonia set by American Thoracic Society/Infectious Diseases Society of America in 2005 and the Guidelines for the early management of patients with acute ischemic stroke set by American Heart Association/American Stroke Association in 2013 including patting on the back of patients in prone position routinely in order to facilitating expectoration,phlegm elimination with physical vibration and apophlegmatic agent application during their stay in ICU.Incidences of SAP and 28-day mortality were calculated.Levels of inflammatory markers (white blood cell,WBC;highsensitive C-reaction protein;procalcitonin,PCT) in serum were detected.Adverse events related to laryngoscopy were documented.Results There were no significant differences in incidences of SAP and 28-day mortality between PG and CG groups (32.20％ vs.41.18％,P ＞ 0.05;47.37％ vs.53.57,P ＞ 0.05,respectively).However,there was statistically significant difference (P ＜ 0.05) in the ICU stay length and inflammatory markers,and the sputum suction process in PG did decrease the incidence of artificial airway establishment and mechanical ventilation (18.64％ vs.35.29％,P ＜ 0.05),and the laryngoscope euthyphoria method was proved to be a protective factor (HR =0.515;95％ CI 0.281-0.057,P =0.038).WBC and PCT were lower in PG group than in CG group (P ＜ 0.05).Conclusion Sputum suction under laryngoscope can reduce the probability of artificial airway establishment and invasive ventilator employment in patients with AIS,shortening ICU stay length and down-regulating levels of WBC and PCT.

Objective To investigate the association between the level of advanced oxidation protein products (AOPP) in serum and the dialysate glucose exposure dose in patients undergoing non-diabetic maintenance peritoneal dialysis (PD). Methods In this cross-sectional study, the levels of serum AOPP were measured in 192 non-diabetic PD patients. Based on the exposure dose of dialysate glucose , PD patients were assigned into the high-dose exposure and low-dose exposure groups. Serum C-reactive protein levels were also measured and the rates of cardio-vascular disease (CVD) were recorded in both groups. Results The levels of serum AOPP were higher in the high-dose exposure group, as compared with the low-dose exposure group [(78.7 ± 15.6) mmol/L vs. (71.7 ± 14.8) mmol/L, P = 0.003]. The serum C-reactive protein levels [4.6 (3.0-11.4) mg/L vs. 3.0 (2.2-5.3) mg/L, P < 0.001] and the rates of CVD (53.6% vs. 35.8%, P = 0.014) were also higher in the high-dose exposure group. After multivariate adjustment ,the level of serum AOPP was independently associated with dialysate glucose exposure dose (β = 0.157, P = 0.031) and duration of PD (β = 0.164, P =0.043). Conclusion The serum AOPP levels are associated with the dialysate glucose exposure doses in non-diabetic PD patients. Minimizing the glucose load might reduce the risk of developing CVD.
ABSTRACT
Objective To explore the change of function and expression of hematopoietic lineage cell specific protein-1 (HS1) and phosphorylated HS1 (p-HIS) and factors devoting to HS1 phosphorylation in platelet with sepsis.Methods Plasma with rich platelet was collected from 150 sepsis patients and 50 healthy subjects, and comparison of platelets adhesion and aggregation were detected by micro-pore method and platelet aggregation instrument.Meanwhile the ATP concentrations of washed platelet of two groups were detected by the kit to compare release reaction.And then total HS1 (t-HIS) and p-HS1 of platelet from two groups were compared by using western blot.Afterwards the specific inhibitors of Src and Syk were used to verify the HS1 activation regulated by Src and Syk in LPS-induced cell model.Results The significant differences were present between healthy subjects and sepsis patients in platelet counts, platelet distribution width (PDW) and mean platelet volume (MPV) (P ＜ 0.01).The data showed the sepsis patients had greater ability than healthy subjects in adhesion, aggregation and release reaction.Meanwhile the platelets of sepsis patients had higher concentration of t-HS1 and p-HS1 than healthy subjects, and the specific inhibitors of Src and Syk , PP2 and piceatannol, inhibited the increase in p-HS1 in LPS-induced cell model.Conclusions Function of platelet is closely related to HS1 in sepsis and it will be a target for sepsis therapy.
ABSTRACT
Objective To study the changes in interleukin-32 (IL-32) in rats with Klebsiella bacillus pneumonia and approach its significance. Methods Seventy-two Sprague-Dawley(SD)rats were divide into control group,model group and experimental group by the method of random digits table,then the experimental group was subdivided into 4 hours and 1,3 and 5 days experimental subgroups(each n=6). The rat model of Klebsiella bacillus pneumonia was established by injection of 0.3 mL Klebsiella bacterial suspension into the trachea. Before the establishment of the model in the experimental group,IL-32 inhibitory agent,protease activated receptor-2(PAR2) was injected into the abdominal cavity. After model establishment,at different time points,blood was collected via tail vein to observe the changes in serum levels of IL-32,tumor necrosis factor-α(TNF-α),IL-6 and IL-8 in all the groups. The lungs were removed and stained with hematoxylin-eosin(HE)method to investigate the histopathological changes of the lung tissues under the light microscope. Results Compared to the control group, with the prolongation of time the levels of IL-32,TNF-α,IL-8 and IL-6 were increased gradually in the model group,and reached their peaks at 3 days〔IL-32(ng/L):84.40±28.24 vs. 18.57±3.86,t=5.544,P=0.002;TNF-α(ng/L):79.27±14.64 vs. 17.82±3.86, t=9.994, P=0.000;IL-8(ng/L):55.85±10.90 vs. 16.66±3.76,t=8.544, P=0.000;IL-6(ng/L):56.65±2.57 vs. 28.48±2.11,t=19.693,P=0.000〕;PAR2 could inhibit above indexes significantly,there was statistical difference at 3 days compared with the model group〔IL-32(ng/L):54.13±6.68 vs. 84.40±28.24,t=2.560,P=0.046;TNF-α(ng/L):49.12±3.56 vs. 79.27±14.64,t=4.901,P=0.003;IL-8 (ng/L):22.95±2.52 vs. 55.85±10.90,t=7.204,P=0.000;IL-6(ng/L):36.49±2.63 vs. 56.65±2.57,t=13.443, P=0.000〕. Under the light microscope,the inflammatory changes in the lung tissue in experimental group were milder than those in the model group. Conclusion As a pro-inflammatory cytokine,IL-32 can induce the production of TNF-α,IL-6 and IL-8,and the inhibition of IL-32 production may play a role in suppression of the development of Klebsiella bacillus pneumonia.
ABSTRACT
Five general practitioners were trained for application of the enhancing CalgaryCambridge guide in consultation.The consultation time in 50 patients were recorded before and after training and the satisfaction degree of patients was investigated by questionnaire survey.Results showed that the length of consultation time after training was longer than that before training (490 s vs 277 s,P ＜ 0.05) and also longer than that of specialists (490 s vs 268 s,P ＜0.05).The overall satisfaction rate of patients was increased after training (72％ vs 88％,P ＜0.05).The results indicate that training of Calgary-Cambridge guide for doctor-patient communication can improve the communication skills of general practitioners.
ABSTRACT
Objective To investigate the relationships between the level of heat shock protein (HSPs) 70 and severity of sepsis in order to find its effects on the status of sepsis and the prognosis of the patients. Methods In total, 120 patients diagnosed to be suffering from sepsis from the emergency department were selected as studying subjects. According to SAPS Ⅱ score, all of these patients were divided into mild, moderate and severe groups (n =40 in each group) , and at the same time, 40 healthy volunteers were studied as controls. The levels of intracellular HSPs70 in peripheral blood neutrophil cells in the mild, moderate and severe groups were determined by using flow cytometry, while serum levels of procalcitonin (PCT) and C-reactive protein ( CRP) were measured as well. Results ① The levels of heat shock proteins HSPs70 in neutrophil cells and PCT in patients with sepsis escalated gradually with the increase in SAPS Ⅱ score, and there were significant different among the mild, moderate, and severe sepsis groups(P<0.05). ② In all septic patients, the death happened only in the severe group. Compared other markers in the survivals , the level of heat shock protein HSPs70 was significantly higher in fatal patients. ③ In curve plot analysis in the patients with sepsis done by the curve of receiver operating characteristic (ROC) , the area of HSPs70 in neutrophil cells under the curve was significantly larger as compared with that of PCT and CRP. Conclusions Heat shock protein HSPs70 has a certain clinical value in determining the severity of disease and prognosis of patients suffering from sepsis.
