Objective To observe the tolerance and positive reaction of skin prick test and skin press test in patients with anaphylactic disease. Methods 80 cases of patients with allergic asthma, rhinitis and other anaphylactic disease were tested by the two tests with specific allergens simultaneously and patients discomfort and scare degree was evaluated, the detection results of specific allergens by the two tests were al-so compared.The results underwent statistical description andχ2 test. Results The difference of the posi-tive rates of allergens between two tests had no significance.Most patients were willing to accept skin press test. Conclusions The results of two tests were similar. But patients receiving skin press test suffer little pain and less fear and are easy to accept the test. So skin press test can substitute for skin prick test in clinical practice.

BACKGROUND: There exists insufficient study with specific applicability regarding vascular distribution characteristics of sural nerve nutrient vessels of the distally based flap.OBJECTIVE: To investigate the distribution of sural nerve nutrient vessels of the distally based flap and provide an anatomical evidence for the design of operation on repair of foot injury.DESIGN: A single sample study.SETTING: Research Center of Clinical Anatomy, Fuzhou General Military Hospital of Nanjing Military Area Command of Chinese PLA, and Department of Orthopaedics, the 97 Hospital of Chinese PLA.PARTICIPANTS: Thirty-two samples of lower extremities whose blood vessels were perfused with red emulsion were provided by Research Center of Clinical Anatomy, Fuzhou General Military Hospital of Nanjing Military Area Command of Chinese PLA.METHODS: The origin of the blood vessels of distally based flap and deep communicating branches of the lesser saphenous vein in the samples were dissected and observed.MAIN OUTCOME MEASURES: ①The nutrient vessels of sural nerve of distally basde flap.②The nutrient vessels of lesser saphenous vein of distally based flap.③The superficial and deep communicating branches of lesser saphenous vein of distally based flap.RESULTS: There were 2 to 5 nutrient vessels in the distally based flap:one originating from the perforating branch of the lateral calcaneal artery was (0. 6 ± 0.2) mm in diameter and one from the terminal perforating branch of the peroneal artery was(0.8±0. 2) mm in diameter and they were (1.0 ± 1.3) and(2. 8 ± 1.0) cm, respectively, away from the lateral malleolus. The incidence of intermuscular septum perforating branches (0 to 3) was 96. 7%, 66.7% and 20. 0%, respectively, and their diameter was (0.9 ±0. 3), (1.0 ±0. 2) and (0. 8 ±0. 4) mm and their distance to lateral malleolus was(5.3 ±2. 1), (6. 8 ±2.8) and (7.0 ±4.0) cm, respectively. There were 2 types of nutrient vessels of the lesser saphenous vein of distally based flap, the nutrient vessels of nerve-vein and the ones of vein-nerve. The superficial and deep communicating branches of the lesser saphenous vein were(1.7 ±0. 5) mm in diameter and(3.4 ±0. 9) cm away from the lateral malleolus. They ended at the peroneal veins.CONCLUSION: The perforating branches of heel lateral artery, the terminal perforating branches and intermuscular septum perforating branches of the peroneal artery have sub-branches to deep fascia, skin, nerves and parenteral nutrient vessels. These sub-branches communicate and form vascular chain of lesser saphenous vein to sural nerve and vascular network of superficial and deep fascia. The superficial and deep communicating branches end at the peroneal veins.

Objective To investigate the expression and its clinical significance of adisintegrin and metalloprotease-17 (ADAM17) in human glioma.Methods The expressions of ADAM17 in human glioma were detected by immunohistochemical staining.The correlation between ADAM17 expression and the malignance of glioma was analyzed.Results Expression of ADAM17 in human gliomas increased.With the malignant degree,ADAM17 expression has also further increased.However,there was a less ADAM17 expression in normal human brain.The positive expression of ADAM17 in low malignant group was 75％ (18/24),of which 1 case were strong positive.The strong positive expression of ADAM17 was the majority (82.1％,23/28) in malignant group.Conclusion The expression of ADAM-17 was higher in human brain gliomas.With malignance degree increased,of the ADAM-17 expression has gradually increased,suggesting that ADAM-17 might play a certain role in the occurrence and development of glioma.

Objective Discussion leukoreduction of red blood cells suspended in two different storage bag placement and he-molysis rate impact on the supernatant free hemoglobin (FHb),to ensure the clinical transfusion is safe and effective.Meth-ods Selected 20 donors to sample 400 ml whole blood per person to make leukodepleted red blood cells,which were evenly divided into 10 bags.The 10 bags were randomly divided into two groups,one to the upright position,one group of horizon-tal.The two groups were stored under the same conditions.Respectively,in the 7,14,21,28,35 day,randomly removed one storage bag from each group,FHb and red blood cell hemolysis rate were measured and analyzed statistically.Results FHb and hemolysis rate results stored in the first 21 days of testing,uprightgroup were (217.310±48.477)mg/L and (0.250± 0.056)%,respectively horizontal group (173.972±39.027)mg/L and (0.189±0.045)%,the results set upright than hori-zontal group,the results were statistically(t=3.114,P =0.003<0.05 and t=3.798,P =0.001<0.05),the difference was statistically significant.Conclusion In the blood storage period,storage bags can be placed horizontally to reduce the de-struction of red blood cells,blood storage is more favorable.

Objective To investigate the characteristics of muscle edema and fatty infiltration in thighs and relationship with clinical symptoms in Chinese patients with different phenotypes of dysferlinopathy.Methods A total of 32 patients were enrolled , including 13 limb-girdle muscular dystrophy 2B (LGMD2B), 13 Miyoshi myopathy (MM), 4 proximodistal myopathy and 2 hyper-creatine-kinase-emia.Clinical symptoms were evaluated using modified Gardner-Medwin and Walton ( GM-W) score.Muscle MRI was performed in thighs to observe fatty infiltration and edema.We then compared the age of onset , disease duration, GM-W score, muscle edema and muscle fatty infiltration between LGMD 2B and MM groups,and the relationship of muscle edema score and fatty infiltration score with disease duration and GM-W score in all patients.Results The median GM-W score was 4.00 (2.00,5.00) in all patients, 4.00 (3.00,4.50)in LGMD2B and 4.00(2.00,5.00)in MM, respectively.Muscle fatty infiltration appeared in 30 cases (93.75%), with the same pattern in LGMD2B and MM.The mean fatty infiltration score was 28.20 ±12.86 in all patients, 28.50 ±13.03 in LGMD2B and 29.00 ±12.63 in MM, respectively.Muscle edema appeared in 26 cases (81.25%) with same pattern in LGMB2B and MM.The mean edema score was 18.36 ±13.60 in all patients, 22.88 ±11.59 in LGMD2B and 16.77 ±13.80 in MM.The age of onset , disease duration, GM-W score, muscle fatty infiltration and edema score were not significantly different between LGMD2B and MM patients.Muscle fatty infiltration score significantly correlated with GM-W score (rs=0.737,P=0.000) and disease duration (rs=0.637,P=0.000).Conclusions Fatty infiltration and edema in thigh muscles are very common in patients with dysferlinopathy , with similar radiological changes in main subtypes.The muscle fatty infiltration can be used as a predictor of disease progression.

Objective To evaluate the effectiveness of standardized management for patients with type 2 diabetes in Beijing Qinan community.Methods Total 484 patients with type 2 diabetes in Qinan community were under standardized management.A cross-sectional study on the effectiveness of diabetes management was conducted in December 2016 based on the health records and clinic medical records.Results The mean age was(71.2 ± 11.2) years,the duration of diabetes was (12.2 ± 7.8) years,the mean BMI was(24.76 ± 3.06) kg/m2 in 484 patients.The TC was(5.08 ± 3.27) mmol/L and LDL-C was(2.72 ±0.78)mmol in 383 patients.The rate of achieving the target level of fasting blood-glucose was 51.96％ (199/383);the rate of achieving glycosylated hemoglobin target was 60.08％ (155/258);and the rate of achieving quick fasting blood-glucose target was 51.49％ (52/101).There were 80.37％ (389/484) patients with clinic blood pressure ＜ 140/90 mmHg(1 mmHg =0.133 kPa),36.57％ patients (177/484) had normal BMI;and 17.83％ patients (46/258) with controlled clinic blood pressure,fasting blood glucose,glycosaylated hemoglobin and LDL-C.There were 53.79％ patients with LDL-C ＜ 2.6 mmol/L and 23.24％ with HDL-C ≥ 1.0 mmol/L.The patients with fasting glucose ＜ 7.8 mmol/L had lower LDL-C than the patients with fasting glucose ≥ 7.8 mmol/L,(F =4.42,P =0.04),The patients with fasting glucose ＜ 7.8mmol/L had higher HDL-C than the patients with fasting glucose ≥ 7.8 mmol/L (Z =-2.30,P =0.02).The rate of achieving glycosylated hemoglobin target was decreased with the increasing of disease duration (x2 =12.57,P =0.01).Conclusion The comprehensive target-reaching rate of type 2 diabetes patients with standardization management in Qinan community is relatively low.It is necessary to strengthen the control of blood lipid,body weight and blood pressure for improving the effectiveness of standardized management of diabetic patients.

Objective: To survey on the home blood pressure measurement and blood pressure control rate among patients with hypertension in Beijing Yuetan community. Methods: A questionnaire survey was conducted among 504 hypertensive patients, who were visiting Beijing Yuetan Community Health Service Center and selected by convenience-sampling method during June 2018 to January 2019. The status of home blood pressure measurement, the awareness of hypertension, the blood pressure control rate and factors related to not regularly measuring were surveyed. Results: Of the 504 patients, 93.7% (472/504) took regular medication, but only 61.5% (310/504) had regular blood pressure measurements; 92.5% (466/504) had sphygmomanometers at home with electronic type mainly; 89.9% (453/504) patients knew the method of blood pressure measurement, but only 11.5% (52/453) had their sphygmomanometer calibrated. Among those who measured blood pressure, 77.4% (240/310) measured per week. The main reason for not measuring blood pressure regularly was that there was no need to measure blood pressure without any discomfort, accounting for 50.0% (97/194). The office blood pressure control rate (with desktop mercury sphygmomanometer) was 62.3% (314/504); the blood pressure control rate both in the morning and at bed time was 61.3% (73/119), that in the morning was 68.1% (81/119) and at bed time was 75.6% (90/119). The control rates of systolic blood pressure and heart rate by home measurement at morning and bedtime were significantly higher than those by office measurement (χ²=5.02, 9.97, 15.51, 13.72; all P<0.05). Conclusions The home blood pressure monitoring rate and knowledge level of hypertension among patients with hypertension in Yuetan community are relatively low. There are some differences in blood pressure control rate between office measurement and home measurement. Comprehensive evaluation is needed in the management process, and the treatment plan should be adjusted according to the specific condition of patients.

OBJECTIVETo investigate the relationship of the mutational status of the ND4 gene and the clinical features of acute myelogenous leukemia (AML) patients with ND4 mutations.

METHODSUsing PCR combined with directly sequencing, we identified somatic mutations of ND4 in 121 primary AML patients to couple with their clinical features.

RESULTSThere were 58 male patients and 63 female patients (median age 49 years, 10-86 years). Eight of 121 patients (6.6%) with de novo AML were found harboring missense mutation of ND4 gene, including 3 patients with A131V (3/8, 37.5%), 2 patients with A404T (2/8, 25%), 1 patient with F149L (1/8, 12.5%), 1 patient with G242D (1/8, 12.5%) and 1 patient with Y409H (1/8, 12.5%), respectively. Patients with ND4 mutations were associated with good karyotype (P=0.049), regardless of gender, age, white blood cell, hemoglobin, platelet, blast cells of bone marrow or immunophenotype (P>0.05). There were no statistical significance in mutations of FLT3-ITD, NPM1, CEBPA, c-KIT and DNMT3A between patients with ND4 mutation and wild-type (wt) ND4 (P>0.05). The median overall survival of patients with ND4 mutations and wt ND4 were all not reached. The median relapse-free survival were not reached and 29(2-53) months, respectively (P>0.05). There was no significance in the ratio of CR and RR patients between wt ND4 and ND4 mutated groups (P>0.05).

CONCLUSIONIt was concluded that novel ND4 mutations could be found in de novo AML patients, especially in patients with good karyotype. Thus, ND4 mutations might play an important role in AML prognosis. However, whether the mitochondria dysfunction contribute to leukemogenesis needs to be further investigated.
