Objective To explore a quick and feasible method of screening malaria parasite by using a Sysmex XE-2100 hematology analyzer though alarm information on high eosinophil count and atypical eosinophil distributions in the WBC scattergram. Methods Sysmex XE-2100 hematology analyzer was used for complete blood cell analysis. Microscopic review was used when high eosinophil count and atypicaleosinophil distributions in the WBC scattergram were found. If the review showed normal eosinophil cells, wecontinued to focus on red cell for searching malaria parasite. Results Among 1 501 specimens showing higheosinophil counts and atypical eosinophil distributions, nine cases with normal eosinophil cells were indisaccordance with the hematology analyzer, six of them showed high eosinophil count in the Sysmex XE-2100 hematology analyzer, whose distribution was located close to neutrophil clusters in scattergram. The otherthree had an abnormal WBC scattergram. There was no gap between eosinophil clusters and neutrophilclusters, which brought no classified results. But all the nine specimens had been found the trophozoite,schizont and merozoite in blood smears. Conclusions There were great possibility of the existence of themalaria parasite in specimens when hematology analysis showed high eosinophil count and atypical eosinophildistributions in the WBC scattergram in a Sysmex XE-2100 hematology analyzer, although these alarm wasnot comfirmed by microscopic review. This method provides not only a simple and reliable way for quickscreening malaria parasite but also has a great value in preventing the undetected ratio on malaria parasite.

OBJECTIVETo explore the impacts on the life quality and the effect mechanism in the patients of allergic rhinitis (AR) treated with warm acupuncture in winter and summer.
METHODSTwo hundred and forty patients of AR were randomized into a summer and winter acupuncture group, a non-summer and winter acupuncture group and a western medication group, 80 cases in each one. In the two acupuncture groups, Dazhui (GV 14), Fengmen (BL 12), Feishu (BL 13), Pishu (BL 20) and Shenshu (BL 23) were selected. In the summer and winter acupuncture group, the warm acupuncture started at the first day of the three periods of hot season and the first day of the third nine-day period after the winter solstice. The treatment was given once every two days, continuously for 15 times. Totally, 30 treatments were required a year. In the non-summer and winter acupuncture group, the warm acupuncture was applied out of the three periods of the hot season and the third nine-day period after the winter solstice. The treatment was given once every two days and 30 treatments for a year. In the western medication group, cetirizine was taken orally, continuously for 30 days as one session. In the three groups, the treatment for 1 year was taken as one session. The second session started in the next year. Totally, 2 sessions were required. The score of rhinoconjunctivitis quality of life questionnaire (RQLQ) and the level of serum immunoglobulin E (IgE) were compared in the patients' of each group before treatment and in 1 and 2 sessions of treatment.
RESULTSAfter treatment, the scores of 7 domains, named activities, common complaints, practical problems, sleep, ocular symptoms, nasal symptoms and emotions were all improved as compared with those before treatment, in the patients of the three groups (all P < 0.05). After 2 sessions treatment, the results in the summer and winter acupuncture group were better than those in the other two groups (all P < 0.05), and the results in the non-summer and winter acupuncture group were better than those in the western medication group (all P < 0.05). After treatment, serum IgE level was lower averagely than that before treatment in the three groups (all P < 0.05). After 2 sessions treatment, the result in the summer and winter acupuncture group was lower than that in the other two groups (both P < 0.05), and the result in the non-summer and winter acupuncture group was lower than that in the western medication group (P < 0.05). After treatment, the total effective rate was 92.3% (72/78) in the summer and winter acupuncture group, better than 80.5% (62/77) in the non-summer and winter acupuncture group and 69.7% (53/76) in the western medication group (both P < 0.05).
CONCLUSIONThe warm acupuncture in both summer and winter achieves the definite efficacy on AR and the effect mechanism is relevant with reducing serum IgE level.

Objective:To investigate the effect of free anterolateral thigh perforator flap in repair of forefoot injuries combined with multiple tissue defect.Methods:A retrospective case series study was conducted on 26 patients who suffered from forefoot injuries combined with multiple tissue defect admitted to 920th Hospital of Joint Logistic Support Force of PLA from January 2015 to December 2019. There were 21 males and 5 females, aged 15-61 years [(31.6±12.5)years]. The combined injuries were fracture in 10 patients, arsometatarsal joint dislocation in 3, bone defect in 9, tendon injury in 5, and ligament injury in 3. Management of multiple tissue defect of the forefeet: soft-tissue defect of the forefeet was resurfaced with free anterolateral thigh perforator flaps with the dimension of 6.0 cm×3.5 cm to 26.5 cm×10.0 cm; fracture was fixed by Kirschner wires; joint dislocation was treated by open reduction and Kirschner wires fixations; bone defect was reconstructed either by one-stage bone graft or by use of membrane-induced technique and secondary bone graft, according to the wound conditions; tendon injury of extensor digitorum longus was repaired by direct tendon suture or by tendon transfer; tarsometatarsal ligament injury was primarily sutured. The flap survival rate was observed within 2 weeks after operation. The fracture healing, bone-defect repair, foot appearance, and donor-site healing were detected at 1 month, 3 months, 6 months, 1 year post-operatively and at the last follow-up. The postoperative complications were recorded. The foot function was assessed using American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score before operation and at the final follow-up.Results:All patients were followed up for 6-36 months [(20.5±4.6)months]. All flaps survived uneventfully. The fracture healing and bone defect repair were acquired. The flap showed good texture, including primary flap thinning in 11 patients and secondarily thinning in 15 patients at 3-6 months postoperatively. The donor sites showed good healing, leaving only a linear scar. The flap venous crisis developed in 1 patient and survived after emergency vascular exploring. Local infection of flap occurred in 3 patients and was cured after further debridement and the use of sensitive antibiotics. The AOFAS ankle-hindfoot score was 54-94 points [(76.6±10.4)points] at the last follow-up, compared to preoperative 11-51 points [(27.2±11.3)points] ( P<0.01). The results were excellent in 5 patients, good in 11, and fair in 10, with the excellent and good rate of 62%. Conclusions:For forefoot injuries combined with multiple tissue defect, anterolateral thigh perforator flap transplantation with additional techniques to treat fractures, bone defect, tendon and ligament injuries can achieve satisfactory results in aesthetic appearance of the flap and donor site and foot function recovery.
