Objective To observe the intervention effects of fluid wax on the therapeutic course of patients with adhesive small bowel obstruction.Methods Two hundreds and eighty-eight patients with adhesive small bowel obstruction admitted into the Department of Gastrointestinal Surgery of Huzhou Central Hospital from December 2014 to June 2016 were enrolled, and they were divided into a fluid wax group and acontrol group by mechanical sampling method, each group 144 cases. The control group was treated with conventional comprehensive non-surgical treatment, in the fluid wax group, on the basis of the above conventional treatment, additionally after 2 hours of gastrointestinal decompression, the fluid wax 3 mL/kg was injected through a gastric tube that then was closed by a clip for 2 hours. The first exhaust and defecation times, the time for amelioration of abdominal pain, the time of gas-liquid flat disappearance, the length of stay in hospital, the rate of operation and the occurrence of adverse reactions were observed in the two groups.Results After treatment, the first exhaust time, the first defecation time, the time of relieving abdominal pain, the time of gas-liquid flat disappearance and the length of stay in hospital were significantly shorter in fluid wax group than those in control group [the first exhaust time (hours): 29.97±19.71 vs. 49.28±33.61, the first defecation time (hours): 60.25±28.37 vs.74.23±50.12, the time of relieving abdominal pain (hours): 35.78±20.98 vs. 51.83±25.02, the time of gas-liquid flat disappearance (hours): 71.60±39.50 vs. 90.98±57.91, the length of stay in hospital (days): 7.00±3.77 vs. 9.00±5.81, allP < 0.05], and the rate of operation in the fluid wax group was lower than that in the control group [18.75% (27/144) vs. 27.08% (39/144),P < 0.05]. No patients died in the two groups. In nearly 1 year follow-up, there were no adverse reactions associated with the study in the fluid wax group.Conclusion The intervention of fluid wax combined with conventional non-surgical methods can significantly shorten the disease course, reduce the rate of operation and the hospitalization time in patients with adhesive small bowel obstruction.

Abstract: Objective To investigate the clinical characteristics and diagnosis key points of brain abscess caused by Nocardia asiatica, and provide a clinical basis for diagnosing and treating intracranial infection caused by Nocardia. Methods A case of pulmonary Nocardia asiatica complicated with brain abscess diagnosed at the Second Affiliated Hospital of Hainan Medical University was selected to analyze the clinical manifestations, cerebrospinal fluid characteristics, pulmonary and cranial imaging features, and treatment plan, and to summarize the diagnosis and treatment experience. Results The patient was an elderly woman with a history of diabetes, dry cough was the first symptom without fever or headache. At the beginning of the course, it was diagnosed as pulmonary infection and tuberculosis in the local hospital, and received conventional antimicrobial and anti-tuberculosis therapies, but showed no improvement. The patient developed progressive limb weakness, followed by consciousness disorders, and coma. Cerebrospinal fluid (CSF) adenosine deaminase and lactate dehydrogenase were not abnormal, CSF pressure, protein and white blood cells were high, mainly with multiple nuclear cells. CSF glucose and chloride were normal in the early stage of the disease, but decreased significantly in the later stage. Metagenomic analysis of cerebrospinal fluid indicated Nocardia asiatica with a specific sequence number of 537. Lung CT showed exudation, abscess, and cavity in the right lung. Skull MRI scan + enhancement suggested multiple scattered abscesses in both cerebral hemispheres. The abscesses were of different sizes and showed ring enhancement, with extensive surrounding edema, and ventricular compression. After treatment with meropenem, linezolid, and compound sulfamethoxazole tablets, the cerebrospinal fluid recovered, and the lesions in the lungs and intracranial structures improved. Conclusions Brain abscess caused by Nocardia asiatica is similar to the tuberculous brain in clinical symptoms, cerebrospinal fluid examination, craniocerebral imaging, so we should be alert to the possibility of Nocardia infection in patients with diabetes. At the same time, metagenomic testing of the cerebrospinal fluid can help confirm the diagnosis. The mortality and disability rates of brain abscess caused by Nocardia are high. Early diagnosis and treatment can improve the prognosis.

OBJECTIVETo observe the dynamic expression changes of p38 mitogen-activated protein kinase (p38MAPK), nucler facter kappa B (NF-κB) and cyclooxygenase-2 (COX-2) in myocardial tissue after an exhausted exercise and study the impact of p38MAPK, NF-κB and COX-2 on its myocardial damage.
METHODSSixty Wister male rats were randomly divided into the control group (n = 10) and the exhausted exercise group (n = 50). Then the exhausted exercise group was further divided into 5 subgroups, namely 0 h, 3 h, 6 h, 12 h, 24 h after an exhausted exercise (n = 10). The myocardial injury animal model was set up by using an exhausted swimming exercise and the expression of p-p38MAPK, NF-κB and COX-2 were examined by Western blot.
RESULTSCompared with the control group, the expression of p-p38MAPK were increased significantly (P < 0.01) in all the groups and the 3 h group was the highest( P < 0.01); The expression of NF-κB were increased significantly (P < 0.05) in all the groups but 0 h P > 0.05) and the 6h group was increased significantly compared with the other groups( P < 0.05); The expression of COX-2 were increased significantly( P < 0.05) in all the groups but 0 h and the 24 h groups was increased significantly compared with the other groups(P < 0.05).
CONCLUSIONp38MAPK was activated in an acute exhausted exercise, p-p38MAPK may play an important role in modulating NF-κB and COX-2 expression and mediating the exhausted exercise induced myocardial damage.

OBJECTIVETo explore the therapeutic effect and mechanism of Aitongping capsule (ATP) in treating cancerous pain.
METHODSSixty cancer patients were randomly divided into two groups, 30 patients in the treated group took ATP and 30 patients in the control group took diclofenac, 1 week of treatment was applied. The relevant clinical conditions of cancerous pain, the content of plasma beta-endorphin (beta-EP) and c-AMP, hemorheological index, improuement of life quality of patients, occurrence rate of adverse reaction were observed before and after treatment.
RESULTSThe total effective rate in the treated group and in the control group was 90.0 % and 83.3%, respectively, difference between them showed no significance. However, there were significant difference between the two groups in such aspects as the degree of pain relieving, the decrease of pain episodes, the shortening persistent time of pain and the initiation time of analgesic action and prolonged analgesic duration, the decrease of tenderness and percussion pain, the increase of plasma beta-EP content and the decrease of cAMP (P< 0.05 or P< 0.01). The evidences also showed that it was better in improving quality of life, ameliorating hemorheologic indexes and reducing incidence of adverse reaction in the treated group than in the control group (P <0.05 or P <0.01).
CONCLUSIONATP has affirmative effect on cancerous pain, its analgesic effect may be associated with the increasing of plasma beta-EP content, decreasing of cAMP level and ameliorating of hemorheologic indexes.
