[Clinical analysis of 5 cases of acute poisoning by inhalation of hydrochlogen chloride]

Objective: To analyze the clinical characteristics caused by acute poisoning by inhalation of hydrogen chloride (HCl) and to raise awareness and treatment level of the disease. Methods: The clinical manifestations, imaging features, diagnosis, treatment and prognosis of 5 patients with acute HCl poisoning were analyzed retrospectively. Results: Among the 5 cases of HCl poisoning, 2 cases were severe poisoning, 3 cases were moderate poisoning. All patients were treated with corticosteroids and symptomatic treatment, one of them was treated with venovenous extracorporeal membrane oxygenation (VV-ECMO) . All patients were recovered and discharged from hospital. Conclusion: The lung damage of acute poisoning by inhalation of HCl is rapidly progressing, early detection and timely medical treatment can obtain a better prognosis.

[Study on changes in cytokines of infertile women with mycoplasma infection and intervention with traditional Chinese medicines]

OBJECTIVE

To investigate the changes in cytokines (IL-1beta, IL-2, TNF-alpha) of peripheral blood and cervical mucous of infertile women with mycoplasma infection and the effect of intervention of traditional Chinese medicines (TCMs).

METHOD

According to the results of culture of mycoplasma from genital tracts, 72 patients with positive mycoplasma were randomly divided into the TCM group (38 cases) and the western medicine group (34 cases). The western medicine group was treated with 0.5 g azithromycin for 3 days and consecutively treated for six courses of treatment, each course of treatment of 4 days. The TCM group were treated with Xiaozhi decoction twice every day for 6 weeks. The IL-1beta, IL-2 and TNF-alpha levels of the peripheral blood and cervical mucous of the two groups were measured by the Ria testing before and after the treatment, and the mycoplasma culture (-) of 32 infertile women as set for control.

RESULT

Before the treatment, TNF-alpha and IL-1beta in levels of the two treatment groups were higher than those of the control group (P < 0.01). In the TCM group, TNF-alpha and IL-1beta levels showed significant differences compared with those before the treatment (P < 0.05) and those of the western group after the treatment (P < 0.01); and IL-2 level didn't have significant change before and after the treatment. The cytokines in peripheral blood of the two treatment groups showed notable difference compared with those of the control group (P < 0.01). In TCM group, IL-2 level had remarkable difference compared with that before the treatment (P < 0.01) and compared with the control group after the treatment (P < 0.01).

CONCLUSION

Cytokines (IL-1beta, IL-2, TNF-alpha) in the peripheral blood and cervical mucous increase in infertile women with the mycoplasma infection, suggesting that TCMs can effectively inhibit the levels of IL-1beta, IL-2, TNF-alpha in the peripheral blood and IL-1beta, TNF-alpha in cervical mucous. It is proved that Xiaozhi decoction can be used to treat infertile women with mycoplasma infection.

Crossbreeding of Phyllostachys species (Poaceae) and identification of their hybrids using ISSR markers

Crossbreeding is an efficient means to increase production and quality in plants; however, hybridization is seldom reported in bamboo. We crossbred two bamboo species Phyllostachys kwangsiensis (female parent) and Phyllostachys bambusoides (male parent) for the first time, and obtained suspected bamboo hybrids. We identified two bamboo hybrids from the above parents using PCR/ISSR. We concluded that ISSR markers are useful to identify bamboo hybrids, and that breeding between bamboo species is possible and useful.
