Efficacy of Xuebijing Injection (血必净注射液) on Cardiopulmonary Bypass-Associated Pulmonary Injury: A Prospective, Single-center, Double Blinded, Randomized Controlled Trial

Objective: To evaluate the efficacy of Xuebijing Injection (血必净注射液, XBJ) on the lung injury induced by cardiopulmonary bypass (CPB). Methods: Fifty patients undergoing CPB were randomized to either the saline group or XBJ group according to a random number table (25 cases in each group). The patients in the saline group received saline and patients in XBJ group received XBJ at 12 h prior to the operation, at the beginning of the operation, and at 12 h after the second injection. The PaO2/FiO2 at extubation 3 days post-operation, duration of ventilation in the intensive care unit (ICU), and lengths of stay in the ICU and hospital were recorded. The levels of inflammatory mediators including interleukin (IL)-1β, IL-8, IL-10, and C-reactive protein (CRP) in bronchoalveolar lavage fluid (BALF) and plasma were measured. The neutrophil count and elastase neutrophil elastase in BALF were also measured. In addition, adverse events were monitored. Results: The PaO2/FiO2 in the XBJ group was higher than that in the saline group from 12 to 72 h post-operation (all P<0.05). The blood levels of IL-1β, IL-8, and CRP in the XBJ group from 12 to 72 h were all significantly lower than those in the saline group (all P<0.05). In contrast, the level of the anti-inflammatory cytokine IL-10 was significantly higher in the XBJ group than in the saline group (P<0.05). In addition, 4 patients presented with atelectasis in the saline group and none in the XBJ group. Ten patients experienced mild acute respiratory distress syndrome (ARDS) during hospitalization, and 5 patients with mild ARDS were in the XBJ group (P<0.05). Conclusion: XBJ shows protective potential against lung injury in patients who undergo CPB surgery, possibly through the downregulation of inflammatory mediators, reduction in neutrophil infiltration, and upregulation of IL-10 (Trial registry: ChiCTR-TRC-14004628).

The Therapeutic Effects of Rehmannia Oral Liquid for the Syndrome of Heat Accumulation with Yin Consumption in Esophagus Cancer Patients Undergoing Radiotherapy——A Report of 60 Cases

Objective: To observe the clinical therapeutic effects of Rehmannia Oral Liquid on the syndrome of heat accumulation with Yin consumption in intermediate or late esophagus cancer patients undergoing radiotherapy. Methods: The IFN-α, TNF-α, IL-1β and TGF-β1 levels in sera were determined by the method of ABC-WLISA before and after the treatment with Rehmannia Oral Liquid. At the same time, the observation was carried out on the patient's general condition, symptoms and signs, barium meal or CT examinations, and biopsy. Another 30 cases of esophagus cancer were treated singly with radiotherapy as the control group. Results: Rehmannia Oral Liquid could obviously improve the patient's general condition, and the symptoms and signs after radiotherapy. Based on the X-ray examination and biopsy, the short-term local control rate of the treatment group and the control group was 70.0% and 40.0% respectively, showing a significant difference (P<0.05). Before the treatment, the level of serum IFN-α of both cancer groups was lower and the levels of TNF-α, IL-1β and TGF-β1 were higher than that of normal group. After treatment, the level of IFN-α in both treatment group and control group increased significantly (P<0.01), and the treatment group improved more obviously than the control group (P<0.05). The level of TNF-α of both groups decreased significantly (P<0.01) after treatment, and the level of IL-1β decreased in treatment group and increased in control group without the significant difference as compared with that before treatment. The level of TGF-β1 was significantly increased in control group (P<0.05) and decreased in treatment group (P>0.05) after treatment. The difference between groups was significant (P<0.05). Conclusion: Rehmannia Oral Liquid can obviously reduce the radiotherapy reaction, improve the quality of life, and raise the therapeutic effects. The action mechanism of the Liquid may lie in balancing the cytokine network and regulating the disordered signal transmission.

Abstract：

Objective To explore the effects of combined enteral nutrition (CEN) on the hemorheologic parameters and the changing levels of inflammatory factors in an animal model of severe acute pancreatitis (SAP). Methods The experimental animals were divided randomly into 3 groups, i.e. early enteral nutrition (EEN) group, CEN group and parenteral nutrition(PN)group (n=20 each). Enteral nutrition was administered to the EEN and CEN group animals at 24 h and 72 h post-modeling respectively. The PN group animals were supported by parenteral nutrition all time. Hemorrheologic indices of all experimental animals were examined on Days 1, 3 and 7 post-modeling. And the inflammatory factors were examined on Days 1 and 7. Results Compared with the EEN and PN groups, some hemorrheologic indices of the CEN group decreased significantly (P<0.05) on Day 7 post-modeling. They included blood sedimentation, hematocrit (HCT), whole blood high-cut reduction viscosity and whole blood low-cut reduction viscosity. As compared within the CEN group, each hemorrheologic index was lower on Day 7 than that on Day 1 (P<0.05). Except for whole blood high-cut reduction viscosity and erythrocyte aggregation index in the EEN group after a 7-day nutrition support, there was no significant change for all hemorrheologic indices in the PN group. As to the level of inflammatory factors, the values of interleukin 8 (IL-8) and tumor necrosis factor-α (TNF-α) in the CEN group were lower than those in the PN group on Day 7 post-modeling (P<0.05). The values of IL-8 and IL-6 in the CEN group were lower than those in the EEN group on the same day(P<0.05). As compared within the CEN group, the values of IL-6 and TNF-α were lower on Day 7 than those on Day 1 post-modeling (P<0.05). Conclusion The modulatory mechanism of EN over SAP should be achieved by correcting hemorrheologic index change and lowering the level of inflammatory factors. A proper timing of EN is probably the most optimal nutrition support mode of SAP therapy.     

THE RELATION OF PARATHYROID FUNCTION TO PREGNANCY-INDUCED HYPERTENTION

Parathyrin (PTH) and calcitonin were measured with radioimmunoassay in 39 cases of pregnancy-induced hypertension (PIH) in late pregnancy, 76 cases in normal early pregnancy and 278 cases in late pregnancy without PIH. Markedly increased PTH was noted in the women in late pregnancy, indicating the state of secondary hyperparathyroidism. PTH values in the women in late pregnancy with PIH were higher than those in the normal early pregnancy group, but Iower than those in the women in late pregnancy without PIH. The difference between PTH values in the PIH group and late pregnancy without PIH group was of statistical significance (P<0.05), while no significant difference was seen between calcitonin values of the two groups (P>0.05). The results suggest that the pathogenesis of PIH may be related to the function of parathyroid.     

Changes of Neuronal Acetylcholine Receptor Alpha 7 of Peritoneal Macrophage in Experimental Acute Pancreatitis Treated by Chaiqin Chengqi Decoction (柴芩承气汤)

Objective:To investigate effect of Chaiqin Chengqi Decoction(柴芩承气汤,CQCQD) on changes of neuronal acetylcholine receptor alpha 7(nAChRα7) of peritoneal macrophages in acute pancreatitis(AP).Methods:Eighteen Kunming mice were equally randomized into the control group,AP group and CQCQD treatment group.AP was induced by two intraperitoneal injections of 4 g/kg L-arginine at 1 h apart,while control mice received saline injections.At 72 h after the first injection of L-arginine,mice in the treatment group were intragastrically administered 0.1 mL/10 g CQCQD every 2 h for 3 times,whilst mice in the other two groups received the same amount of saline feeding.Mice were sacrificed by cervical dislocation 2 h after the last feeding of either CQCQD or saline.Peritoneal macrophages were collected for determination of nAChRα7 mRNA and protein expression.Serum was collected for detection of interleukin-6(IL-6),IL-10 and acetylcholine(ACh)levels,and pancreas was for histopathology analysis.Results:The CQCQD treatment significantly ameliorated the severity of AP as evidenced by reducing the pancreatic histopathology score(4.5 ± 0.5 vs.6.2 ± 1.7,P0.05)and the serum IL-6 levels(1228.31419.2 pg/mL vs.1589.6 ±337.3 pg/mL,P0.05).The mRNA and protein expression of nAChRα7 of the peritoneal macrophages in the AP group were similar to the control group(P0.05),but were significantly up-regulated after the CQCQD treatment(P0.05).The serum ACh levels in the AP group were significantly lower than those in the control group(3.1 ± 0.6 μg/mL vs 4.8 ± 0.7 μg/mL P0.05),but were significantly increased after the CQCQD treatment(5.6±1.5 μg/mL vs 3.1 ±0.6 μg/mL,P0.05).Conclusion:CQCQD is protective against L-arginine-induced AP through mechanisms involving nAChR α 7 of peritoneal macrophages.     

A retrospective study of continuous renal replacement therapy versus intermitt ent hemodialysis in severe acute renal failure

Objective To investigate the efficacy of continuous renal replacement therapy (CRRT) versu s intermittent hemodialysis (IHD) in patients with severe acute renal failure (A RF).Methods One hundred and ninety -three severe ARF patients who received renal support be tween December 1978 and December 1998 were involved in this study. Of them, 101 (52.3%) were treated with CRRT (CRRT group), and 92 (47.7%) with IHD (IHD gro up).Results Sixty (59.4%) patients in the CRRT group got through the acute phase of disease and 41 (40.6%) patients did not survive while in the IHD group 59 (64.1%) pat ients survived and 33 (35.9%) patients did not. No significant difference in s urvival rate was found between the two groups. 24 of 64 patients (37.5%) in th e CRRT group with multiple organ dysfunction syndrome (MODS) survived, while in the IHD group, 8 out of 44 (27.3%) survived, their survival rate was much lowe r than that in the CRRT group. Patients in CRRT group were more severely ill, a s manifested by lower mean arterial pressure, higher APACHE Ⅱ score, more dysfu nctioned organs and requiring mechanical ventilation and vasopressor support as compared with patients in the IHD group, CRRT was found to improve hemodynamic stability with a better fluid balance and control of biochemical status, increas ed nutritional intake and a shorter duration of acute renal failure (P&lt;0.05 ). Conclusion CRRT perhaps may be the best choice in the treatment of severe ARF patients, for it can offer several distinct advantages compared to IHD. These may contribute to improving the survival rate of ARF patients, particularly those that are cri tically ill patients.

目的探讨选择性头部亚低温（SHC）对新生儿缺氧缺血性脑病（HIE）新生儿血清细胞焦亡相关关键蛋白和细胞因子,包括半胱氨酸天冬氨酸蛋白酶-1（Caspase-1）、白细胞介素（IL）-1β、IL-18水平的影响,以期了解SHC治疗HIE可能的神经保护机制。方法选择确诊为HIE新生儿共45例（HIE组）,同期选取正常新生儿10名作为对照组,其中HIE组按照临床分期分为轻度HIE组13例,中度HIE组20例,重度HIE组12例,并按照亚低温治疗纳入标准将中、重度HIE新生儿32例分为常规治疗组（常规组）15例和SHC治疗组（SHC组）17例。采用ELISA法检测并比较各组新生儿血清Caspase-1、IL-1β、IL-18水平。结果轻、中、重度HIE组新生儿血清Caspase-1、IL-1β水平均高于对照组,且Caspase-1、IL-1β水平均随HIE临床分期加重而上升（P < 0.05）;重度、中度HIE组血清IL-18水平均高于对照组和轻度HIE组（P < 0.05）。HIE新生儿血清Caspase-1、IL-1β、IL-18水平与HIE临床分期均呈明显正相关关系（r_s＝0.820、0.913、0.683,P < 0.01）。SHC组和常规组治疗前血清Caspase-1、IL-1β、IL-18水平差异均无统计学意义（P>0.05）,SHC组治疗24 h血清Caspase-1和48、72 h时血清Caspase-1、IL-1β、IL-18水平均明显低于常规组（P < 0.01）。治疗48、72 h,SHC组Caspase-1、IL-1β、IL-18水平均低于0、24 h（P < 0.05）;常规组48 h时血清Caspase-1、IL-1β、IL-18水平均较0 h上升（P < 0.05）,72 h时IL-1β、IL-18水平仍高于0 h（P < 0.05）,而Caspase-1水平与0 h差异无统计学意义（P>0.05）。结论SHC治疗HIE新生儿可通过减少细胞焦亡水平以达到神经保护作用。
