Preliminary study of lateral tibia periosteum distraction for the treatment of chronic ischemic diseases of lower limbs / 中华骨科杂志

Objective:To investigate the effect of lateral tibial periosteum distraction on diabetic foot and vasculitis foot.Methods:A retrospective analysis of 13 patients (16 feet) who received lateral tibial periosteal distraction between June 2019 and May 2020 were included in the study. 9 males and 4 females; aged 39-77 years (average 66 years); left foot 7 cases, right foot 9 cases. 5 cases were patients with diabetic foot, 1 case was diabetic foot with arteriosclerosis obliterans, 2 cases were thromboembolic vasculitis, and 5 cases were arteriosclerosis obliterans. The tibial periosteum was dissected and a distraction device was placed. In the 3 patients with foot ulcers, tibial periosteum distraction devices were placed on the severer side. The periosteal distraction began on the third day after surgery, about 0.75 mm/d, the adjustment was done usually in two weeks. Two weeks later, the stretch plate was removed surgically. The followings were evaluated: visual analogue scale (VAS) pain score, foot peripheral oxygen saturation, foot capillary filling test, lower extremity arterial CT angiography (CTA), etc.Results:All 13 patients were followed up for 2-12 weeks, with an average of 3.85 weeks. VAS pain score: the average pain score of 13 patients with preoperative foot pain was 5.31±1.84 (range, 2-9) points, and 2 weeks after surgery, the average value was 2.46±1.39 (range, 1-6) points with statistical significance ( t=6.124, P<0.001) ; peripheral foot oxygen saturation: the average preoperative blood oxygen saturation of 12 patients was 87.83%±14.83% (range, 50%-98%), 1 patient was not detected before surgery, and 2 weeks after operation, the average blood oxygen saturation was 92.33%±7.91% (range, 75%-99%). There was no significant difference between them ( t=1.124, P=0.285). The foot skin temperature of 10 patients was 35.68±0.85 ℃ (range, 34.00-36.60 ℃) before surgery and 36.23±0.46 ℃ (range, 35.50-36.90 ℃) after surgery, and the difference was statistically significant ( t=3.197, P=0.008) . Capillary filling test: 2 weeks after operation, the capillary filling response was significantly improved. All 13 patients had improved CTA of both lower extremity arteries before operation, and 11 patients had CTA taken back after two weeks of operation. Compared with preoperative CTA, new vascular network was found in the operation limb. In addition to 1 patient with thromboangiitis obliterans (mainly suffering from foot pain, no wound symptoms), 2 of 12 patients with heart failure, renal failure and other basic diseases did not heal, and the wounds of the other 10 patients had improved significantly 1 month later. Conclusion:Lateral tibia periosteum distraction can be used to treat chronic ischemic diseases of lower extremities with satisfactory postoperative results.

An Outbreak of Histomoniasis in Backyard Sanhuang Chickens

Histomonas meleagridis is a facultative anaerobic parasite, which can cause a common poultry disease known as histomoniasis. The species and age of the birds impacts on the susceptibility, with turkey being the most susceptible species. Chickens are less susceptible to H. meleagridis than turkeys and usually serve as reservoir hosts. Here, the diagnosis of an outbreak of histomoniasis in backyard Sanhuang chickens is described. The primary diagnosis was made based on clinical symptoms, general changes at necropsy, histopathology, and the isolation and cultivation of parasites. The pathogen was further confirmed by cloning, PCR identification, and animal inoculation tests. A strain of H. meleagridis, named HM-JSYZ-C, with a higher pathogenicity level in chickens was obtained. The study lays a foundation for further investigations into H. meleagridis and histomoniasis in chickens.

Application of Genetic Testing in Individualized Antiplatelet Therapy for Acute Coronary Syndrome Pa-tients after Percutaneous Coronary Intervention / 中国药房

OBJECTIVE:To investigate the value of genetic testing in clopidogrel individualized antiplatelet therapy for acute coronary syndrome(ACS)patients after percutaneous coronary intervention(PCI). METHODS:Clinical pharmacists participated in therapy for 3 ACS patients after PCI,and analyzed risk factors of stent thrombosis as the degree of lesion complexity,length and number of stents,complication,smoking history,etc. Clinical pharmacists suggested conducting clopidogrel genetic testing (CYP2C19,PON1,ACBC1),and suggested replacing antiplatelet agents,maintaining original plan and strengthening monitoring according to the results of genetic testing. RESULTS:The physicians adopted the suggestions of clinical pharmacists. After optimiz-ing antiplatelet therapy according to the results of genetic testing and clinical factors,3 patients were stable and discharged from hospital with drugs. CONCLUSIONS:Genetic testing can provide evidence for the formulation of individualized antiplatelet thera-py in ACS patients after PCI,and can be regarded as one of the breakthrough points for clinical pharmacists to carry out pharmaceu-tical care. In conducting genetic testing,clinical pharmacists should evaluate the risk of thrombosis in ACS patients and select the appropriate population for testing. At the same time,the clinical factors as medication compliance,stent thrombosis risk,therapeu-tic efficacy,ADR,and evidence-based pharmaceutical evidence should be comprehensively evaluated on the basis of genetic test-ing,and antiplatelet therapy plan should be optimized so as to guarantee the safety and effectiveness of drug use.

Observation of animal model of life cycle of Angiostrongylus cantonensis / 中国血吸虫病防治杂志

Objective To observe the effect of artificially construction of the life cycle of Angiostrongylus cantonensis in the laboratory condition so as to provide the basis for the research of angiostrongyliasis. Methods SD rats were infected orally with the third?stage larvae of A. cantonensis collected from infected Pomacea canaliculata. Six weeks after the infection the first?stage larvae were isolated and counted from fresh feces of the rats and then were used to infect P. canaliculata. Three weeks lat?er the snails were dissected for counting the third?staged larvae of A. cantonensis. Results The first?stage larvae were detect?ed in the feces of the rats 6 weeks after the infection and the third?staged larvae were successfully isolated after the infection of P. canaliculata. Conclusion The animal model of the entire life cycle of A. cantonensis is successfully established in the labo?ratory with the infection of 50 larvae per rat.

Efficacy of a DNA Vaccine Carrying Eimeria maxima Gam56 Antigen Gene against Coccidiosis in Chickens

To control coccidiosis without using prophylactic medications, a DNA vaccine targeting the gametophyte antigen Gam56 from Eimeria maxima in chickens was constructed, and the immunogenicity and protective effects were evaluated. The ORF of Gam56 gene was cloned into an eukaryotic expression vector pcDNA3.1(zeo)+. Expression of Gam56 protein in COS-7 cells transfected with recombinant plasmid pcDNA-Gam56 was confirmed by indirect immunofluorescence assay. The DNA vaccine was injected intramuscularly to yellow feathered broilers of 1-week old at 3 dosages (25, 50, and 100 microg/chick). Injection was repeated once 1 week later. One week after the second injection, birds were challenged orally with 5x10(4) sporulated oocysts of E. maxima, then weighed and killed at day 8 post challenge. Blood samples were collected and examined for specific peripheral blood lymphocyte proliferation activity and serum antibody levels. Compared with control groups, the administration of pcDNA-Gam56 vaccine markedly increased the lymphocyte proliferation activity (P<0.05) at day 7 and 14 after the first immunization. The level of lymphocyte proliferation started to decrease on day 21 after the first immunization. A similar trend was seen in specific antibody levels. Among the 3 pcDNA-Gam56 immunized groups, the median dosage group displayed the highest lymphocyte proliferation and antibody levels (P<0.05). The median dosage group had the greatest relative body weight gain (89.7%), and the greatest oocyst shedding reduction (53.7%). These results indicate that median dosage of DNA vaccine had good immunogenicity and immune protection effects, and may be used in field applications for coccidiosis control.
