Objective To approach the effect of Shenfu injection (SFI) and conventional early goal-directed therapy (EGDT) on organ functions and outcomes of septic shock patients. Methods Eighty-four cases conformed to the criteria for the diagnosis of septic shock admitted to Department of Critical Care Medicine of Xuzhou Central Hospital were randomly divided into conventional treatment group (42 cases), and SFI treatment group (42 cases). Conventional treatment was given in the two groups;in SFI treatment group, SFI 100 mL was additionally given by trace continuous intravenous pump 20 mL/h, twice daily for 7 days. Before and after treatment for 1, 6, 12, 24, 48, 72 hours, the levels of hemodynamic status, lactic acid and dosage of vasoactive drugs used, organ function, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, sequential organ failure assessment (SOFA) score, the time of weaning from ventilator, the length of stay in intensive care unit (ICU), time without organ failure and 28-day mortality rate were observed. Results Compared with those before treatment, after treatment in the two groups, the mean arterial pressure (MAP), cardiac index (CI) and systemic vascular resistance index (SVRI) were increased, while the levels of heart rate (HR) and lactate were decreased (all P<0.05). Compared with conventional treatment group, in SFI treatment group, after treatment for 24 hours, the MAP level was increased significantly [mmHg (1 mmHg=0.133 kPa):75.40±9.75 vs. 71.80±11.08, P < 0.05], that continued to 48 hours; after treatment for 6 hours, the CI level was increased obviously (mL·s-1·m-2: 75.18±34.84 vs. 67.35±39.34, P < 0.05) , that continued to 48 hours; after treatment for 6 hours, the lactic acid level was decreased markedly (mmol/L: 2.03±0.82 vs. 2.24±0.97, P < 0.05);in the comparison of dosage of vasoactive drugs used between two groups, the difference was not significant (all P >0.05). Compared with that before treatment, in the conventional treatment group after treatment for 1 and 3 days, gamma glutamyl transpeptidase (GGT) was increased, on the 5th day it began to decrease, reaching its minimum on the 7th day (U/L:26.75±16.74 vs. 46.96±25.85);while in SFI treatment group, GGT was increased after treatment for 1 day, on 3rd day it began to decrease, reaching its lowest level on the 7th day (U/L:22.41±17.87 vs. 51.23±27.74);aspartate aminotransferase (AST), total bilirubin (TBil), oxygenation index (PaO2/FiO2) were increased after the treatment for 1, 3, 5, 7 days, and blood urea nitrogen (BUN), creatinine (Cr) were decreased at different time points after treatment. In the conventional treatment group, the precursor protein (PA) was decreased after treatment for 1, 3, 5 days, on the 7th day it was increased (mg/L:134.20±63.44 vs. 115.70±45.96);while in SFI treatment group, after the treatment for 1 days and 3 days, it was decreased, on the 5th day it was increased, reaching its highest level on the 7th day (mg/L:145.40±59.75 vs. 108.20±54.34). Compared with those before treatment, after treatment for 1, 3, 5, 7 days, APACHEⅡscore and SOFA score were decreased in the two groups, but there was no statistically significant difference in APACHEⅡscore between the two groups, in SFI treatment group after treatment for 3 days, SOFA score was significantly lower than that of the conventional treatment group (6.31±3.86 vs. 7.14±4.03, P<0.05), that continued to the 7th day after treatment. In SFI treatment group, the time for weaning from ventilator (days:7.5±3.5 vs. 9.1±3.2) and the length of stay in ICU (days: 16.1±9.2 vs. 18.7±8.3) were significantly shorter than those in conventional treatment group (both P<0.05). There were no significant differences in time without organ failure (days:14.5±4.2 vs. 15.3±3.1) and 28-day mortality rate [28.6%(12/42) vs. 31.0%(13/42)] between SFI group and conventional group (both P>0.05). Conclusion The combined use of SFI and EGDT can improve hemodynamics, reduce damage to vital organs, and shorten the times for ventilation and stay in ICU in septic shock patients.

BACKGROUND:The incidence of low serum level of vitamin D in patients undergoing hip arthroplasty and its impact has not been reported in China, indicating that it has not been brought to the forefront. OBJECTIVE:To determine the prevalence of low serum level of vitamin D in patients before total hip arthroplasty and its relationship with the hip function scores. METHODS:Forty-eight hips from 48 patients undergoing primary hip arthroplasty from July 2013 to August 2014 in the First Affiliated Hospital of Suzhou University were enrol ed. According to the serum level of vitamin D, patients were assigned to low-level (<20μg/L) and high-level (20≥μg/L) groups. The general information of patients, the hip function scores before and after replacement at the last fol ow-up in the two groups were observed and compared. The relationship between the serum level of vitamin D and the hip function scores before and after replacement was analyzed by multiple linear regression analysis. And the average fol ow-up was 12 months (11-14 months). RESULTS AND CONCLUSION:(1) The incidence of low vitamin D level was 82%(20 ng/mL serving as standard). (2) Compared with patients with high vitamin D level, patients with low level of vitamin D had lower preoperative Harris scores and Merle D′Aubigne-Postel score (P<0.05), and also at the last fol ow-up (P<0.05. (3) Based on the preoperative and postoperative Harris, the multiple linear regression analysis showed that there was a positive correlation between the level of vitamin D and Harris score both preoperatively and postoperatively (P<0.05). (4) These results suggest that there is a higher incidence of low level of vitamin D in patients undergoing arthroplasty, and hip function scores before and after replacement in patients with low level of vitamin D are lower than the high level patients. Moreover, there is a positive correlation between the level of vitamin D and the hip joint function scores. Therefore, it is advisable to supplement vitamin D and calcium preoperatively, and the level of vitamin D wil be helpful for disease assessment and prognosis.

Objective To investigate the relationship between the expression level of heat shock protein B1 (HSPB1) and radiotherapy. Methods We used the gastric cancer data from TCGA. The data was randomly splited to two parts,one as testing data,another one as validation data. Results The results showed that the expression did not associate with overall survival,both on testing and validation data. For patients with high expression of HSPB1,there was no significant different between radiotherapy and nonradiotherapy group. The adjusted HR were 1. 08(0. 38 ～ 3. 09) and 1. 38(0. 53 ～ 3. 64),with P values 0. 89 and 0. 51 for testing and validation data,respectively. Interestingly,for patients with low expression of HSPB1,significant different between radiotherapy and nonradiotherapy group was observed. The adjusted HR were 0. 22(0. 06 ～ 0. 81) and 0. 03(0. 003 ～ 0. 220),with P values 0. 02 and 1. 07 × 10 - 3 for testing and validation data,respectively. Conclusion These results suggest that low expression of HSPB1 strongly associates with radiosensitivity. The survival rate of patients with low expression of HSPB1 after radiotherapy is significantly increased,suggesting that HSPB1 may be a potential molecular marker for precision radiotherapy of gastric cancer.

The 34 cases in the treatment group were treated with allicin injection through Murphy drip for a course of 10 days with nitroglycerin group as control. Results demonstrated that the total effective rate for symptoms and ECG were 82% and 62% respectively for the treatment group. It also markedly lowered the level of plasmal endothelin, and that of blood sugar in diabetics'. Adverst effects included local pain at the injection site and headache, the incidence of which were 18% and 6% respectively. This therapy is a satisfactory one for stubborn angina pectors.
