[Human skin infestation caused by Haemolaelaps casalis: a case report].

Our study reports a case of acarodermatitis caused by Haemolaelaps casalis. By morphological observations, the mites seized were identified as Haemolaelaps casalis (deutonymph) which could attack humans resulting in acarodermatitis characterized with the symptoms of papules and blisters in different degrees. The patient was treated with 15% calamine lotion and anti-inflammatory and antipruritic drugs. Meanwhile, the mites were eliminated in the bedroom. After the treatment for one week, the patient was cured. Haemolaelaps casalis, which had been found in the indoor mattress, could attack humans and cause acarodermatitis. We should strengthen the work of anti-mite in domestic environment.

[Optimization and comparison of extraction methods of mitochondrial DNA of Oncomelania hupensis].

OBJECTIVE: To optimize the extraction methods of mitochondrial genome DNA (mtDNA) of Oncomelania hupen- sis. METHODS: The pyrolysis, protein K variable-temperature digestion and high-concentration potassium acetate purification were applied to optimize the high-concentration-salt precipitation method, and then the optimized method was compared with two common extraction methods, the sucrose density gradient centrifugation method and traditional high-concentration-salt precipitation method. The mtDNA samples were identified by using spectrophotometry, agarose gel electrophoresis and the amplification products of COX1. The nuclear DNA contamination was tested by the amplification products of ITS. RESULTS: The concentration and yield of the improved method was significantly higher than those of the traditional method (F = 3 032.65, 10 185.00, both P < 0.01). The mtDNA samples extracted were essentially free of nuclear DNA and protein, meeting PCR, sequence analysis and other molecular biology research requirements. CONCLUSIONS: The improved high-concentration-salt precipitation method for isolating mtDNA is simple, and it has high yield and low cost. The extracted mtDNA can meet relevant analysis requirements.

Analysis of clinical effect and application value of Dahuoluo capsule combined with acupuncture therapy in treatment of sequelae of stroke / 中国生化药物杂志

Objective To analyze the clinical effect and application value of Dahuoluo capsule combined with acupuncture therapy in treating stroke sequelae. Methods 80 patients with brain stroke sequelae were enrolled in this study from January 2016 to January 2017, and were randomly divided into the observation group (n= 40) and the control group (n=40). The control group was given Dahuoluo capsule, and the observation group was treated with Dahuoluo capsule combined with acupuncture therapy. The therapeutic effects of the two groups were compared and analyzed. Results The total effective rates in the observation group (97.5%) was significantly higher than the control group (75.0%) with significant difference (P<0.05); the daily activity ability scores of the observation group 15d, 30d after treatment were significantly higher than the control group with statistical significance (P<0.05). There was no statistical significance in the incidence of adverse reactions between the observation group (2.5%) and the control group (5.0%). Conclusion Dahuoluo capsule combined with acupuncture therapy has significant clinical effect on the treatment of patients with stroke sequelae, and the efficacy of which is safe and reliable.
