OBJECTIVETo investigate the protective effect and mechanism of Xingnaojing(Traditional Chinese Medicine) injection on brain injury in rats.

METHODSSixty-three healthy adult male SD rats were randomly divided into 3 groups (n = 21): sham operation group, model group, xingnaojing group. The model of traumatic brain injury model group and Xingnaojing group used the free fall impact injury method, the sham operation group underwent craniotomy, did not cause brain damage. Xingnaojing group in rats after 10 min by tail vein injection Xingnaojing injection 10 ml/(kg x d), model group and sham operation group were intravenously injected with 0.9% sodium chloride solution, three groups were administered continuously for 7 days. At administration of the seventh days compared the S-100B protein in the serum and neuro specific enolase (NSE) level, the water content of brain tissue, serum superoxide dismutase (SOD), malondialdehyde (MDA) and glutathione peroxidase (GSH-Px) content, and neurological function of rats among groups.

RESULTSCompared with the sham operation group, the nerve defect, brain water content, MDA, S100B protein and NSE levels were obvigusly increased in Xingnaojing group and model group; SOD, GSH-Px content decreased significantly; In Xingnaojing group nerve impairment and brain moisture were significantly lower than those of model group, the serum MDA, S-100B protein and NSE levels were significantly lower than those in the model group, the SOD, GSH-Px activity was significantly higher than that in the model group.

CONCLUSIONXingnaojing injection has protective effects on rat brain injury, and its mechanism may be related to reduce brain edema after traumatic brain injury and inhibit the reaction of oxygen free radical, protect nerve cells.

Objective To approach the effect of different vasopressor on hemodynamics, volume responsiveness, fluid volume balance, renal function and prognosis in patients with acute respiratory distress syndrome (ARDS) complicated with septic shock.Methods A prospective single-blind randomized controlled trial was conducted. ARDS patients with septic shock admitted to the Department of Critical Care Medicine of Jiangxi Provincial People's Hospital from January 1st, 2015 to May 1st, 2016 were enrolled. The patients satisfied ARDS Berlin diagnostic criteria, over 15 years old, needing vasopressor after fluid resuscitation were enrolled. The patients were divided into norepinephrine group (NE group) and terlipressin group (TP group) by randomise number table derived by computer. Patients in TP group were given terlipressin (0.01-0.04 U/min) with an intravenous pump, while those of NE group were given norepinephrine (> 1μg/min) with an intravenous pump, and the target mean arterial pressure (MAP) was maintained at 65-75 mmHg (1 mmHg = 0.133 kPa). Hemodynamics and extravascular lung water index (EVLWI) were monitored by pulse indicator continuous cardiac output (PiCCO). The volume responsiveness of patient was evaluated by passive leg raising (PLR) test, and cardiac index (CI) change (ΔCI ≥ 10%) served as positive volume responsiveness. The differences in hemodynamics, EVLWI, oxygenation index (OI), lactate clearance rate (LCR), rate of positive volume responsiveness, urinary output, fluid volume balance, renal function, and prognostic indicators were compared between the two groups.Results Fifty-seven patients with ARDS complicated with septic shock were enrolled, with 26 patients in NE group, and 31 patients in TP group, thebaseline data in both groups was balanced with comparability. Compare with NE group, 48-hour and 72-hour heart rate (HR) in TP group was significantly slowed (bpm: 82.1±6.8 vs. 87.6±7.4, 81.3±6.1 vs. 85.6±8.3, bothP < 0.05), 72-hour central venous pressure (CVP) was significantly decreased (mmHg: 9.4±2.6 vs. 10.9±3.0,P < 0.05), but no significant difference was found in HR, MAP, CVP, CI, EVLWI, OI and LCR at other time points between the two groups. 48-hour and 72-hour positive volume responsiveness rate in TP group were significantly increased as compared with those of NE group (74.2% vs. 46.2%, 64.5% vs. 38.5%, both P < 0.05), urinary output on the 2nd day (mL/24 h: 2342.8±704.1 vs. 1944.6±684.3) and fluid volume balance (mL: -319.7±54.8 vs. -169.6±27.2) were significantly decreased (bothP < 0.05). There was no significant difference in positive volume responsiveness rate, urine output, fluid volume balance, and the level of serum creatinine at other time points between the two groups. There was no statistically significant difference in the following features between TP group and NE group: duration of mechanical ventilation (days: 8.41±2.97 vs. 9.67±3.56), length of intensive care unit (ICU) stay (days: 12.84±4.47 vs. 14.77±5.01), total length of hospital stay (days: 19.34±7.37 vs. 21.07±8.41), and 28-day mortality (29.0% vs. 30.8%, allP > 0.05).Conclusions Compared with norepinephrine, terlipressin for ARDS patients with septic shock is more conducive to restrict fluid load, improve the renal perfusion and increase urine output. However, in both groups therewas no significant difference in the efficiency of stabilizing hemodynamics, shortening the duration of mechanical ventilation, reducing ICU or hospital days and decreasing 28-day mortality.

To analyze the regularity in combined medication with Xiyanping injection (Xiyanping for short) in the real world by as- sociation rules. Totally 5 822 patients using Xiyanping injection was collected from the 18 Class III Grade I hospitals nationwide to study the combined medication information of the patient with lung infection and make the analysis by using association rules and Apriori. According to the results, major drugs combined with Xiyanping in treatment of lung infection included compound amino acid, inosine, coenzyme A, cytidine triphosphate, vitamin C. Common drugs combined with Xiyanping can be divided into 5 categories: nutrition support therapy (vitamin C, compound amino acid) , coenzymes (coenzyme A, cytidine triphosphate, inosine), expectorants and antiasthmatics (ambroxol, salbutamol, doxofylline), hormones (dexamethasone, budesonide), antibiotics (mainly cefminox). The main combined medicines mostly conformed to the regularity for drugs treating lung infection. In addition, there were two most common medical combination models: the model for Xiyanping combined a single medicine is Xiyanping + nutrition support therapy, while the model for Xiyanping combined two or more than two medicines is Xiyanping + nutrition support therapy + coenzyme. Pharmacologically, Xiyanping is mostly combined with western medicines with similar pharmacological effects to substitute or supplement the antibiotic effect in treating lung infection. However, further studies shall be conducted for the safety and rationality of the combined medication based on clinical practices, in order to provide reference for clinical medication.

After comparing the varieties of parameters in batch culture under different dissolved oxygen tension by Bacillus pumilus, we found that the demand of cell on oxygen in different phase isn' t consistent. Based on the analys is of the metabolic pathway of oxygen and the mechanism of the effect of dissolved oxygen tension on fermentation of D-ribose, a two-stage oxygen-supply control mode was proposed and experimentally proved to be available. High ribose yield and high glucose consumption rate were achieved during whole process for 44h, and the ultimate ribose concentration and cell concentration were 5.0% and 18.8% higher than former respectively.

Objective:To observe the effect of moxibustion on T lymphocyte subsets in peripheral blood of rats with gastric cancer. Methods:Sixty healthy Sprague-Dawley (SD) rats were adaptively fed for one week. By the random number table method, 10 rats were randomly selected as a blank group, and 12 rats were randomly selected to simulate the tumor transplantation process; after transplantation, 10 rats were randomly selected as a sham operation group. The remaining 38 rats were used to prepare gastric cancer models by gastric transplantation of the Walker-256 tumor tissue; 8 rats were randomly selected to verify the successful modeling after 7 d; the remaining 30 rats were randomly divided into a model group, a moxibustion group and an infrared group by the random number table method, with 10 rats in each group. From the first day of enrollment, the rats in the moxibustion group received mild moxibustion at Zhongwan (CV 12), Guanyuan (CV 4) and bilateral Zusanli (ST 36) (the first group) and bilateral Pishu (BL 20) and Weishu (BL 21) (the second group), and the two groups of acupoints were alternated every other day. The rats in the infrared group received infrared radiation on the stomach area and the area on the back between the T12-T13 spinous processes, the two areas were alternated every other day. Rats in the moxibustion group and the infrared group were treated for 20 min each time, once a day for 21 d. Rats in the blank group, the sham operation group, and the model group were simultaneously grasped and fixed, and no other treatment was performed. After 21 d of intervention, the rats in each group were fasted for 12 h, and blood was collected from the orbits. The numbers of CD3+, CD3+CD4+, CD3+CD8+ T lymphocytes in peripheral blood were determined by flow cytometry, and the ratio of CD3+CD4+/CD3+CD8+ was calculated. The rats were sacrificed and the thymus was dissected under sterile conditions to calculate the thymus index. Results:Compared with the blank group, the thymus index, peripheral blood CD3+, CD3+CD4+, CD3+CD8+ and CD3+CD4+/CD3+CD8+ ratio in the sham operation group did not change significantly (allP>0.05). Compared with the blank group, the thymus index of the model group was increased (P<0.05), the CD3+ and CD3+CD8+ T lymphocytes were increased (bothP<0.01), and the CD3+CD4+/CD3+CD8+ ratio was decreased (P<0.05). Compared with the model group, the thymus index of the moxibustion group was increased (P<0.01), and CD3+, CD3+CD4+ and CD3+CD8+ T lymphocytes and the ratio of CD3+CD4+/CD3+CD8+ in peripheral blood were increased (allP<0.05). Compared with the infrared group, the thymus index of the moxibustion group was significantly increased (P<0.05), the CD3+ and CD3+CD4+ T lymphocytes in the peripheral blood were significantly increased (bothP<0.01), and the CD3+CD8+ was increased (P<0.05). Conclusion:Moxibustion can significantly increase the thymus index of gastric cancer-bearing rats and activate CD3+CD4+ and CD3+CD8+ T lymphocytes in peripheral blood.
