Objective To explore the effects of Shenfu injection combined with low-dose hydrocortisone on plasma lev?els of human leukocyte antigen (HLA)-DR and procalcitonin (PCT) in patients with septic multiple organ dysfunction syn?drome. Methods A total of 118 patients with septic multiple organ dysfunction syndrome were divided into three groups:control group (n=39), experimental group 1 (n=39) and experimental group 2 (n=40). The control group received conventioanl medicine therapy, while the experimental group 1 received Shenfu injection (100 mL, 2/d, for 7 d) combined with conventio?anl medicine therapy, and the experimental group 2 received Shenfu injection combined with low-dose hydrocortisone (200 mg/d, for 14 d) besides conventional medicine therapy. The peripheral blood samples were collected for the detection of HLA-DR, PCT and lipoperoxide (LPO) before treatment, 1 d, 3 d amd 7 d after treatment. The mortality in 14 d was record?ed. Results The mortality rates in 14 d were 61.5%(24/39), 41.0%(16/39) and 25.0%(10/40) for control group, experimen?tal group 1 and experimental group 2 (χ2=8.15, P<0.05). There were no significant differences in PCT, HLA-DR and LPO levels before treatment and 1 d after treatment between the three groups (P>0.05). The plasma levels of PCT and LPO were significantly decreased in control group, experimental group 1 and experimental group 2 after 3-d and 7-d treatment, but the levels of HLA-DR was significantly increased (P < 0.05). Conclusion The combination therapy of Shenfu injection and low-dose hydrocortisone can effectively reduce PCT level and increase HLA-DR level, which promotes the improve?ment of patients with septic multiple organ dysfunction syndrome.

Objective:To investigate the relationship between base level of Cyfra21-1,SCCA,TK1 and lung cancer prognosis.Methods: A nested case-control study was conducted.721 lung cancer cases who had no distant metastasis were recruited baseline population from January 2010 to January 2013.About 2 years follow-up,364 cases of death or brain (or multiple) metastasis were identified as case group, and the other 357 cases were included in the control group.The level of serum Cyfra21-1,SCCA,TK1 was detected.The relationship between base level of Cyfra21-1,SCCA,TK1 and lung cancer prognosis were analyzed.Results: The age in the case group was (59.3±10.1),and the control group was (59.0±9.9).There were obvious differences in body mass index,smoking index,pathological type,clinical stage,lymph node metastasis and with chronic diseases between case group and control group(P<0.05),while no difference in pleural effusion,comprehensive treatment etc(P>0.05).There were differences in the base level of Cyfra21-1,SCCA,TK1;and there were differences in Cyfra21-1,SCCA,TK1 distribution between case group and control group(P<0.05).There was difference in the base level of Cyfra21-1(P<0.05),while no differences in SCCA,TK1(P>0.05) in patients with different stages of lung cancer.There were differences in the base levels of Cyfra21-1 and SCCA(P<0.05),while no differences in TK1(P>0.05) in patients with different pathological types of lung cancer.Logistic regression analysis results showed that the OR value of SCCA,TK1 with lung cancer prognosis were respective 7.235(1.674-14.613),5.009(0.973-10.778),5.816(0.879-16.235).Conclusion: The baseline level of Cyfra21-1 can reflect the prognosis of lung cancer patients,while SCCA,TK1 not.

OBJECTIVE: To investigate the mechanism of the pulmonary injury in rats caused by chronic intermittent hypoxia (CIH) and to investigate the intervention effect of Edaravone. METHOD: Ninety-six male Wistar rats were divided into four groups randomly: the control group (NC), chronic intermittent hypoxia group (CIH), chronic intermittent hypoxia normal saline matched group (NS), chronic intermittent hypoxia edaravone treatment group (NE). The four groups were also divided into 1, 2, 3, 4 W time subgroups, and each time subgroup had 6 rats. After the experiment, sections of pulmonary were stained with hematoxylin-eosin (HE) and the level of SOD, MDA, PO2 and Ang II mRNA in rat homogenate pulmonary were measured. RESULT: Pulmonary histology revealed that the CIH group showed high levels of interstitial edema, alveolar atelectasis, inflammatory cell infiltration of alveolar epithelial cell, pulmonary injury were serious in 1, 2, 3, 4 W. But the pulmonary histology of the UC group and the NS group was normal. Compared with the NS group, pulmonary injury of NE group 1, 2, 3, 4 W, significantly decreased. Compared with the NC group, the levels of PO2 in the CIH group were decreased; while the compared with the NS group, the levels of PO2 in the NE group were increased. Compared with the UC group and NS group, the levels of Ang II mRNA in each time point in CIH group were increased gradually (P < 0.05), the content of MDA were increased in 1, 2, 3, 4 W (P < 0.05), they had reached the peak all at 4 W; while the SOD in each time point in CIH group were decreased gradually (P < 0.05) compared with that in UC group and NS group; The Ang II mRNA levels of CIH in pulmonary showed positive correlation with MDA [r = 0.782,P < 0.01]; while the Ang II mRNA levels of CIH in pulmonary showed negative correlation with SOD [r = - 0.904, P < 0.01]. CONCLUSION CIH can cause pulmonary injury through oxidative stress and activating Ang II, and Edaravone could prevent pulmonary injury induced by CIH through scavenging oxygen free radicals.

This study is to investigate the effect of the effective components group of Xiaoshuantongluo (XECG) on neuronal injury induced by oxygen-glucose deprivation (OGD) in primary cortical cultures isolated from SD rat cortex at day 3 and the possible mechanism. Cells were divided into control group, OGD model group and XECG group (1, 3 and 10 mg x L(-1)). The cell viability was assessed with MTT assay and the LDH release rate was measured by enzyme label kit. The cell apoptosis was analyzed using Hoechst staining. RT-PCR was applied to detect the mRNA levels of JAK2 and STAT3. Western blotting was used to detect the expressions of Bcl-2, Bax, p-JAK2 and p-STAT3 proteins. Results showed that XECG resulted in an obvious resistance to oxygen-glucose deprivation-induced cell apoptosis and decrement of cell viability, decrease the cell LDH release rate. XECG could adjust the expression of Bcl-2 and Bax proteins and increase Bcl-2/Bax ratio, up-regulate the expression of p-JAK2 and p-STAT3. In conclusion, XECG could protect against the neuronal injury cells exposed to OGD, which may be relevant to the promotion of JAK2/STAT3 signaling pathway, and impact the expression of Bax and Bcl-2.

OBJECTIVE: To study the expression of Survivin in laryngeal squamous cell carcinoma (LSCC) and laryngeal papilloma in adults and its significance in carcinogenesis and development of the LSCC. METHOD: The expressions of Survivin protein were detected by immunohistochemistry technique in 46 cases of LSCC, 24 cases of adjacent nontumorous laryngeal epithelium, 20 cases of laryngeal papilloma and 16 cases of normal laryngeal epithelium. RESULT: The positive rates of Survivin protein expression in laryngeal carcinoma, adjacent nontumorous laryngeal epithelium and laryngeal papilloma were 71.74% (33/46), 33.33% (8/24)and 40.00% (8/20) respectively. There was no expression in normal laryngeal epithelium. The positive rate of Survivin protein expression in laryngeal carcinoma was significantly higher than that in the adjacent nontumorous laryngeal epithelium, laryngeal papilloma and normal laryngeal epithelium. But there was no statistically significant correlations between Survivin protein expression and the clinicopathological characteristics of tumor site, T-stage, pathological grading, UICC-stage and lymph node metastasis (P > 0.05). Expression of Survivin protein in 3 cases in laryngeal papilloma group which turned into laryngeal carcinoma later were all positive. CONCLUSION There was overexpression of Survivin in the laryngeal carcinoma. The expression of Survivin might play an important role in the carcinogenesis of LSCC and might be an early event during laryngeal carcinogenesis. It could be a diagnostic marker for evaluating the malignant potential of laryngeal papilloma in adults.

Objective: Preliminary study on the clinical effect of preoperative ultrasound endoscopy combined with staining labeling technique to locate the actual boundary of esophageal and gastric cancer Methods: From September 1, 2015 to October 30, 2017, 18 patients with esophageal adenocarcinoma were enrolled in this study. The actual boundaries of esophageal and gastric-derived adenocarcinoma lesions were localized by endoscopic ultrasonography and staining. There were 10 males and 8 females. After completing the preoperative examination, 1-2 days before operation, endoscopic ultrasonography was used to locate the edge of the lesion. Two point injection of carbon nano suspension was used to mark the location of 1cm at the longest distance from the longitudinal axis of the tumor. According to the length of longitudinal axial staining, the thoracotomy was performed. Intraoperative proximal margin resection was used to send frozen pathology. According to the results of freezing, the operation was decided. After the operation, the specimens from the margin of the tumor were segmented into paraffin section, which was about 0.5cm in each segment, and the tumor cells were observed under the electron microscope at all levels of the paraffin sections. Results: The average time of preoperative endoscopic ultrasonography staining was(10.16±1.38) min, and the diameter of nano carbon diffusion was(1.43±0.41)cm. All patients in the operation could clearly see the nano carbon staining area under the naked eye. In the field, the average time of locating lesions was(1.27±0.53)min. 5 patients underwent thoracoabdominal surgery and 13 underwent abdominal surgery. The average length of the cut margin of the tumor was(4.74±1.12)cm, and the frozen pathology of the incision margin was negative, and no additional operation was performed. The routine pathology confirmed that all the specimens were negative. Conclusion The staining and labeling technique for adenocarcinoma of the esophagogastric junction under endoscopic ultrasonography can detect the tumor edge and the scope of invasion accurately. It provides guidance and guarantee for the smooth implementation of AEG precision surgery. It is a safe, rapid and effective positioning technique.
