OBJECTIVETo investigate whether inhalable particulate matters can cause the damage of chromosome or mitotic apparatus to produce micronucleus, and to evaluate genetic toxicology of moxa smoke on chromosome.

METHODSBy MTT method, the 24 h half maximal inhibitory concentration (IC50) of moxa smoke condensation (MSC) on Chinese hamster ovary (CHO) cells was 0.087 mg/mL. CHO cells, which were cultured in vitro, were divided into a solvent control group, a positive control group (cyclophosphamide as solvent), a low concentration group, a moderate concentration group and a high concentration group. The low concentration group, moderate concentration group and high concentration group were set approximately 1/8, 1/4, 1/2 of IC50, respectively. Whether micronucleus had dose-effect response induced by the damage of chromosome or mitotic apparatus was observed after CHO cells were contaminated by MSC in the low concentration group, moderate concentration group and high concentration group.

RESULTSThe rate of micronucleus induced by MSC in the low concentration group, moderate concentration group and high concentration group was higher than that in the solvent control group (all P < 0.05), which presented dosage-effect response. The experiment was repeated 3 times, indicating it was repeatable with statistical significance.

CONCLUSIONHigh concentration of MSC shows toxicity to induce chromosome damage, which disappears at low concentration. The genetic toxicology is also dependent on concentration, and the concentration of moxa smoke is essential. In clinical treatment, it is noted to control the level of moxa smoke, while the clinical safety standard of moxa smoke concentration is in need of further study.

Antiphospholipid syndrome (APS) refers to a group of clinical symptoms and signs caused by antiphospholipid antibody (aPLA). We reported a rare case of poor outcome of a pregnant woman with APS. The pregnant woman had APS, hemolytic anemia, elevated liver function and low platelet count (HELLP) syndrome, and eclampsia and had a poor outcome from a second pregnancy. She was treated with antispasmodics, sedatives, and anti-hypertensive agents, along with anticoagulant therapy and infusion of immunoglobulin. APS during pregnancy often makes pregnancy even more complex and risky. Obstetricians should carry out anticoagulation treatment throughout the perinatal period.

OBJECTIVETo observe the effects of intervention of moxa smoke with different concentrations on superoxide dismutase (SOD) and malondialdehyde (MDA) in serum and lung of male rats, so as to explore the safety concentration of moxa smoke.

METHODSA total of 32 Wistar male rats were randomly divided into a control group, a low-concentration group, a moderate-concentration group and a high-concentration group, 8 rats in each one. All the rats were exposed in the full-automatic toxicant exposure cabinet, and the overshadow of moxa smoke was set at 0%, 10%, 40% and 70%, respectively. Each rat was exposed for 20 min per day. After 26 weeks, the activities of SOD and content of MDA in serum, lung organ and bronchoalveolar lavage fluid were tested.

RESULTSCompared with the control group, the activities of serum SOD in the high-concentration group were reduced (P< 0. 05), but those in the low-concentration group and moderate-concentration group were not significantly different (both P>0. 05). Compared with the control group, the content of serum MDA in the low-concentration group, moderate-concentration group and high-concentration group was increased insignificantly (all P>0. 05). There were no significant differences regarding activities of SOD and content of MDA in lung organ and bronchoalveolar lavage fluid among each moxa smoke group (all P>0. 05).

CONCLUSIONThere is no obvious toxic reaction in the low-concentration group and moderate-concentration group; in the high-concentration group the antioxidant ability is damaged due to long-term exposure.
