OBJECTIVE: To study the distribution and drug sensitivity test of bacteria of patients on chronic rhinosinusitis with or without nasal polyps. METHOD: The purulent discharges were collected from sinus of 175 patients with chronic rhinosinusitis with or without nasal polyps during endoscopic sinus surgery. The results of germiculture and drug sensitivity test were analyzed. RESULT: From 175 specimens, 118 (67%) showed positive results in germiculture. Among them, 79 strains of gram positive bacteria and 39 strains of gram negative bacteria were detected. Staphylococcus epidermidis, Staphylococcus aureus and Staphylococcus haemolyticus were the most common pathogens in gram positive bacteria. The most common pathogens of gram negative bacteria were P. Aeruginosa, Enterobacter aerogenes, Enterobacter cloacae. The sensitive antibiotic on gram positive bacteria were amikacin, Daptomycin, Linezolid, vancomycin, teicoplanin, amoxicillin and clavulanate potassium, cefuroxime, respectively. The sensitive antibiotics on Gram negative bacteria were amikacin, Cefoperazone/sulbactam and imipenem, ceftazidime ceftazidime, aztreonam, levofloxacin, respectively. CONCLUSION Bacterial infection was common happened in the sinus cavity of patients with chronic rhinosinusitis with or without nasal polyps. Gram positive bacteria were the main pathogenic bacteria and gram positive bacteria and gram negative bacteria have great differences in the sensitivity of antibiotics. For patients with chronic rhinosinusitis, the using of antibiotics should depend on the drug sensitivity test.

Objective To investigate the influence of di-(2-ethylexyl) phthalate (DEHP) on cell apoptosis and expression of Bcl-2 and bax in cultured human first trimester cytotrophoblasts. Methods Human first trimester cytotrophoblasts were cultured with DEHP at concentration of 0, 25, 50, 100 μmol/Lfor 24 hours. Cell apoptosis was detected by the terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick-end labeling (TUNEL) and flow cytometer method. The expression of apoptosis-associated genes, including Bcl-2 and bax, were detected by reverse transcription (RT)-PCR in cultured cytotrophoblast cells. The protein expression of Bcl-2 and bax in cytotrophoblast cells was measured by western blot. Results (1) The expression of Bcl-2: when incubated with DEHP at concentration of 0, 25,50 and 100 μmol/L, the expression of Bcl-2 were 1.00 ± 0.05, 1.03 ± 0.04, 1.04 ± 0.03, 1.04± 0.04,which did not show statistical difference ( P > 0.05 ). The expression of Bcl-2 protein were 0.11 ± 0.02,0.11 ±0.04, 0.12±0.02, 0.12 ±0.03, which also didn't reach statistical difference (P>0.05). (2)The expression of bax: when incubated with DEHP at concentration of 50 and 100 μmol/L, the expression of bax protein were 0.63 ± 0.04 and 0.81 ± 0.04, which were significantly higher than 0.23 ± 0.05 with DEHP at 0 μmol/L (P < 0.05). The expression of bax mRNA were 0.96 ± 0.04 and 1.02 ± 0.04, which was significantly higher than 0.81 ±0.05 with DEHP at 0 μmol/L (P < 0.05). (3) Apoptosis: when incubated with DEHP at concentration of 50 and 100 μmol/L for 24 hours, the apoptotic cell ratio were ( 18.8 ± 2.6) % and ( 20.3 ± 2.0) % by annexin V-FITC/PI staining, which were significantly higher than (10.6±1.4)% at 0 μmol/L and (18.1 ±4.6)% and (19.5 ±1.2)% by TUNEL staining, which were significantly higher than ( 11.2 ± 3.1 ) % at 0 μmol/L of DEHP (P < 0.05). Conclusion DEHP could induce apoptosis of cytotrophoblast cells by increasing bax gene expression, but had no effect on Bcl-2 expression.

Objective To observe the clinical effect of oral use and acupoint application of Chinese herbal medicine with the actions of strengthening spleen and regulating stomach, lowering rebellious Qi to stop vomiting in treating pregnant pernicious vomiting. Methods One hundred and twenty-two spleen-stomach deficiency pregnant pernicious vomiting cases were randomly divided into observation group ( N=63) and control group (N=59). At the end of the trial, 2 cases of the control group dropped out, and the total case number was 57 in the control group. Both groups were treated with intravenous infusion, dietary care, daily life and emotional nursing, and oral use of Chinese herbal medicine with the actions of strengthening spleen and regulating stomach, lowering rebellious Qi to stop vomiting. Additionally, the observation group was given acupoint application of herbs for strengthening spleen and regulating stomach, lowering rebellious Qi to stop vomiting. The treatment was performed once a day, 4 days constituted one treatment course, and the treatment lasted two continuous courses. The improvement of vomiting, therapeutic effect and the safety were compared between the two groups after treatment. Results ( 1) The total effective rate was 96.8%in the observation group and was 71.9%in the control group, the difference being significant (P<0.01). (2) The time for stopping vomiting in the observation group was significantly less than that in control group (P<0.01). (3) During the treatment, no obvious adverse reaction was found in the two groups. Conclusion Acupoint application of herbs for strengthening spleen and regulating stomach, lowering rebellious Qi to stop vomiting has obvious synergistic effect on the clinical efficiency of spleen-stomach deficiency pregnant pernicious vomiting treated by oral use of herbal medicine, intravenous infusion, dietary care, and daily life and emotional nursing.

OBJECTIVE: To observe the protective effects of Corydalis ambailis migo total alkaloids (COAMTA) on cerebral ischemia/reperfusion injury in rats and to investigate its mechanism. METHODS: The effects of COAMTA on decapitated gasping mouse model and rat model of middle cerebral artery ischemia (2 h)/reperfusion (22 h) were observed. The neurological scale, cerebral infarcted volume and cerebral water content subjected to cerebral middle artery ischemia/reperfusion in rats were recorded. The activities of nitric oxide synthase (NOS) and superoxide dismutase (SOD) and the content of malondialdehyde (MDA) in the ratso brain were measured. Cell apoptosis in ischemic penumbral area was observed with light microscope in the method of terminal deoxynucleotidyl transferase mediated dUTP-biotin nick end labeling (TUNEL). RESULTS: The average gasping time of the mice (6.0 mg/kg or 9.0 mg/kg COAMTA) was significantly prolonged, the cerebral infarcted volume and cerebral water content of the rats (5.0 mg/kg or 7.5 mg/kg COAMTA) were significantly decreased, as compared with the control groups. The average activity of SOD in cerebral tissue of the rats (5.0 mg/kg or 7.5 mg/kg COAMTA) was significantly higher than that of the control groups, meanwhile, the average activity of NOS and the content of MDA declined significantly. The cell apoptosis in ischemic penumbral area of the rats (5.0 mg/kg COAMTA) was significantly inhibited as compared with the control groups. CONCLUSION: COAMTA can facilitate the protection against cerebral ischemia/reperfusion damage. The mechanism is related to inhibiting the activity of NOS and lipoperoxidation, increasing the activity of SOD and decreasing the neuronal apoptosis.
