BACKGROUND: The occurrence and severity of acute high-altitude disease(AHAD) are determined by the speed entering the highland, the altitude of highland and seasons. The association between obesity and AHAD has not been fully investigated.OBJECTIVE: To investigate the association between obesity and acute high-altitude in people exposed rapidly to the highland.DESIGN: Comparative observation.SETTING: Department of Cardiology, General Hospital of Chinese PLA and Department of Cardiology, Tibetan General Hospital of Chinese PLA.PARTICIPANTS: The experiment was conducted at the Department of Cardiology, General Hospital of Tibetan Military Area Command of Chinese PLA in August 2006. Totally 82 Henan subjects aged 28-45 years were selected from the male workers constructing the Qinghai-Tibet Railway and their managers with acute high-altitude exposure. They had never been to the highland before, and all agreed to the detection.METHODS: ①Every subject completed the AHAD self-report questionnaire at sea level and 12 hours and 24 hours after ascending high-altitude. The items in the questionnaire included symptoms of headache, gastrointestinal symptoms,fatigue or weakness, dizziness, and insomnia. Each symptom was graded from 0-3 with 0 as no symptoms, 1 as mild symptoms, 2 as moderate symptoms, and 3 as severe symptoms and a total score of 15. A score of 4 or more could by identified as AHAD. ②The height and body mass were measured to calculate the body mass (BMI). Those with BMI≥28 kg/m2 served as the obesity group [n =39, mean age (35±8) years], and those with BMI of 18.5-23.9 kg/m2 as the normal body mass group [n =43, mean age (35±8) years]. ③Arterial blood was taken to evaluate arterial oxygen saturation (SO2), arterial oxygen pressure (PaO2) and arterial carbon dioxide pressure (PaCO2) at baseline and 24 hours after ascending high-altitude. ④The measurement data was compared by t test.MAIN OUTCOME MEASURES: BMI, vital capacity of lungs, SO2, PaO2 and PaCO2 levels of obese and normal people.RESULTS: Totally 39 obese people and 43 normal people were involved in the result analysis. ①AHAD score: No symptom was reported at sea level in all participants (scored 0), but the AHAD scores in the obesity group were significantly higher than those in normal group 12-hour and 24-hour after ascending high-altitude. ②Blood gas analysis:At sea level, there were no statistical differences in the levels of SO2, PaO2, and PaCO2 between two groups (P > 0.05).But 24 hours after ascending high-altitude, SO2 and PaO2 of the obesity group were much lower than in the normal group (P< 0.01), and PaCO2 was significantly higher than in the normal group (P< 0.01).CONCLUSION: Obese men are more vulnerable to high-altitude hypoxia than people with normal body mass. Obesity is an important risk factor for the development of acute high-altitude disease.

Objective To analyze the status quo of the diagnosis and treatments of primary gastro-intestinal lymphoma (PGIL) in order to improve it. Methods Eighty-one patients with PGIL were ana-lyzed retrospectively including clinical manifestations, endoscopic features, pathological features, HP in-fection, treatment, and prognosis. Results The age of patients with gastric lymphoma was (52.84±15.33) years. The age of patients with intestinal lymphoma was (42.09±15.28) years. Common symp-toms included abdominal pain (76.5%), gastrointestinal bleeding (55.6%), anemia (54.3%), abdominal mass (25.9%), hypoproteinemia (40.7%), bowel obstruction (11.1%), abdominal dis-tension, vomiting, and other non-specific gastrointestinal symptoms (32.1%), weight loss (33.3%); fever (8.6%), diarrhea (7.4%), digestive tract perforation (1.2%), constipation (1.2%), and dysphagia (1.2%). Endoscopic appearances were as follows: tumor type (67.7%), ulcer type (27.7%), and diffuse type (4.6%). Clinical diagnosis rate and endoscopic biopsy confirmation rate were 30.9% and 73.8%. MALT lymphoma accounted for 61.7% of the patients. HP detection rate was 39.5 % and positive rate was 37.5 %. A total of 69 patients received surgeries: 3 had preoperative chem-otherapy, and 34 had postoperative chemotherapy. Twelve patients had non-surgical treatment, 6 patients of whom had simple chemotherapy and HP eradication therapy, and the other 6 gave up during the treat-ment. There was no significant difference in the survival rate of Stage Ⅰ~Ⅱ patients in the surgery alone group, surgery plus chemotherapy group, and chemotherapy and HP eradication therapy group (P>0.05). The survival rate of Stage IIIⅢ~Ⅳ patients in the surgery alone group was lower than that in the other 2 groups (P<0.05). The 5-year, 3-year, and 1-year survival rate was 55.87%, 70.96%, and 96.39%, respectively. Conclusion There are no specific clinical and endoscopic features in PGIL, so the misdiagnosis rate is high. Multi-site biopsy or repeated biopsies and immunohistochemical methods can be used to raise the pathological diagnosis rate. Chemotherapy and HP eradication are recommended.

Objective To explore the effects of different degrees of intermittent hypoxia (IH) on the activation and the secretion of extracellular matrix in MLg lung fibroblast cell line. Methods MLg lung fibroblast cells in logarithmic growth phase were exposed for 5%O2 for 100 seconds and 21%O2 for 120 seconds in 1 h, 4 h and 8 h groups (IH1, IH4 and IH8) and normoxia group (21%O2 for 8 h, N group). The cells in each group were collected at the end of experiment. Real-time PCR was used to measure the mRNA expression levels ofα-SMA and typeⅠcollagen (COL1) A1, and Western blot assay was used to detect the protein expression levels ofα-SMA and COL1. Results The mRNA and protein expression levels ofα-SMA and COL1 were significantly increased in IH1, IH4 and IH8 groups than those in N group (all P < 0.05). Furthermore, expression levels of α-SMA and COL1 showed a time-dependent increase with IH exposure time. Conclusion The intermittent hypoxia can promote the cell activation and the extracellular matrix secretion of mouse lung fibroblast cells, which may be related with the oxidative stress.
