OBJECTIVE:To discuss the association between ABCB1 gene polymorphisms and adriamycin and cyclophospha-mide(AC)combined with chemotherapy-induced severe neutropenia in patients with breast cancer. METHODS:218 breast cancer patients receiving AC combined with chemotherapy were selected from our hospital during 2012-2015;PCR-RFLP was used to de-tect polymorphisms of ABCB1 2677G>T/A and 3435C>T. The associated between different age,BMI,clinical stages genotypes, etc and AC combined with chemotherapy-induced severe neutropenia were investigated,and risk factors of neutropenia were ana-lyzed by multivariate logistic regression. RESULTS:Among 218 breast cancer patients,170 patients suffered from severe neutrope-nia,accounting for 78.0%. Among ABCB1 2677G>T/A polymorphisms,distribution frequency of GT or GA genotype,TT,TA or AA genotype,GG genotype in severe neutropenia were 80.6%,86.2% and 60.0%,with statistical significance (P<0.05). Among ABCB1 3435C>T polymorphisms,distribution frequency of TT,CT and CC genotype in severe neutropenia were 86.4%, 78.4% and 72.7%,there was no statistical significance(P>0.05). AST and ABCB1 2677G>T/A polymorphisms were correlated with severe neutropenia (P<0.05),and ABCB1 2677G>T/A polymorphism was a strong predictor of neutropenia [OR=3.875, 95%CI(1.555,9.922),P=0.008]. CONCLUSIONS:ABCB1 2677>T/A polymorphisms may be aggravate AC combined with che-motherapy-induced neutropenia in patients with breast cancer.

Objective:To observe the clinical efficacy of Qigui Tangtongning Granules in the treatment of diabetic peripheral neuropathy (DPN) with qi deficiency and blood stasis.Methods:Prospective cohort study. A total of 80 DPN patients with Qi deficiency and blood stasis in Endocrinology Department of the First Affiliated Hospital of Anhui University of Chinese Medicine from May 2021 to May 2022 who met the inclusion criteria were divided into 2 groups by random number table method, with 40 cases in each group. The control group was treated with epalrestat on the basis of routine hypoglycemia, and the treatment group was treated with Qigui Tangtongning Granules on the basis of control group. Both groups were treated for 8 weeks. TCM syndromes were scored before and after treatment. Disease severity was assessed using the Toronto Clinical Scoring System (TCSS). The motor nerve conduction velocity (MNCV) and sensory nerve conduction velocity (SNCV) of median nerve and common peroneal nerve were detected by electromyography/induced potentiometer. Serum CRP, TNF-α and IL-6 were detected by ELISA, fasting blood glucose (FPG) and two hours post-meal blood glucose (2 hPG) were detected by automatic biochemical analyzer, and glycosylated hemoglobin (HbA1c) was detected by automatic HBA1C analyzer. Adverse reactions were recorded and clinical efficacy was evaluated.Results:The total effective rate was 95.0% (38/40) in the treatment group and 77.5% (31/40) in the control group, the difference between the two groups was statistically significant ( χ2=5.17, P=0.023). After treatment, the TCM syndrome score and TCSS score of the treatment group were significantly lower than those in the control group ( t=-3.19 and -7.63, P<0.01); Median nerve SNCV [(47.90±4.51) m/s vs. (44.76±3.72) m/s, t=3.40], MNCV [(53.79±3.65) m/s vs. (51.32±4.25) m/s, t=2.79] and common peroneal nerve SNCV [(44.21±2.08) m/s vs. (40.51±2.49) m/s, t=7.23], MNCV [(44.63±4.72) m/s vs. (41.36±4.87) m/s, t=3.05] were significantly higher than those in the control group ( P<0.01); FPG [(5.05±0.63) mmol/L vs. (7.05±1.23) mmol/L, t=-9.17], 2 hPG [(9.10±1.64) mmol/L vs. (12.19±2.61) mmol/L, t=-6.35], HbA1c [(6.79±0.90) % vs. (7.22±1.02) %, t=-2.02] were significantly lower than those in the control group ( P<0.01 or P<0.05); TNF-α [(15.75±5.44) ng/L vs. (32.01±5.33) ng/L, t=-13.51], hs-CRP [(2.58±0.80) mg/L vs. (3.79±1.04) mg/L, t=-5.83], IL-6 [(18.20±4.92) ng/L vs. (29.97±5.18) ng/L, t=-10.41] were significantly lower than those in the control group ( P<0.01). No obvious adverse reactions were observed in 2 groups during treatment. Conclusion:Qigui Tangtongning Granules combined with conventional Western medicine can improve nerve conduction velocity, reduce inflammation and improve clinical efficacy in DPN patients with Qi-deficiency and blood-stasis syndrome.

ObjectiveTo observe the clinical efficacy of Danzhi Jiangtang capsules with the functions of replenishing Qi, nourishing Yin, and dredging collaterals on patients with type 2 diabetes mellitus (T2DM) combined with lower-extremity macroangiopathy and serum levels of homocysteine (Hcy) and cystatin C (Cys C). MethodA total of 80 eligible patients who were treated in the department of endocrinology of the First Affiliated Hospital of Anhui University of Chinese Medicine from May 2017 to December 2019 were randomized into the treatment group (40 cases) and control group (40 cases). Both groups received the basic therapies for diabetes and Danzhi Jiangtang capsules (oral) was added to the treatment group. The levels of glycosylated hemoglobin A1c (HbA1c), fasting plasma glucose (FPG), 2-hour postprandial glucose (2 hPG), fasting C-peptide (C-P), and 2-hour postprandial C-peptide (2 hC-P), triglycerides (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), and low density lipoprotein cholesterol (LDL-C) and serum levels of Hcy and Cys C were measured and the traditional Chinese medicine(TCM) syndrome scores were calculated before and after treatment in the two groups. ResultAfter 12 weeks of treatment, levels of HbA1c, FPG, and 2 hPG were lower than those before treatment in the two groups (P<0.05). Levels of C-P (P<0.05) and 2 hC-P were higher than those before treatment in the two groups. After treatment, levels of HbA1c, FPG, and 2 hPG in the treatment group were lower than those in the control group (P<0.05), while levels of C-P and 2 hC-P showed no significant difference between two groups. After treatment, the levels of TG, TC, and LDL-C were lower than those before treatment (P<0.05) and HDL-C level was higher than that before treatment (P<0.05) in both groups. After treatment, levels of TG and LDL-C in the treatment group were lower than those in the control group (P<0.05), and levels of TC and HDL-C demonstrated no significant difference between two groups. After the treatment, the TCM syndrome score was lower than that before the treatment in both groups (P<0.05) and lower in the treatment group than in the control group (P<0.05). The overall effective rate of the treatment group was higher than that of the control group (χ2=7.585, P<0.05). The levels of Cys C and Hcy were lower than those before treatment in the two groups (P<0.05) and lower in the treatment group than in the control group (P<0.05). Doppler echocardiography of the lower limbs showed no obvious improvement in the control group after treatment. However, for the treatment group, slight decrease in intima-media thickness of the lower limb arteries and a slight reduction in the plaque area were observed, but the difference was not statistically significant. ConclusionDanzhi Jiangtang capsules has definite therapeutic effect on T2DM combined with lower-extremity macroangiopathy, which can improve glucolipid metabolism and reduce serum levels of Hcy and Cys C. This study can serve a reference for the prevention and treatment of T2DM combined with macroangiopathy.

Objective To examine the effect of ground cage use on Oncomelania hupensis spread, so as to provide insights into precision snail control. Methods Twenty ground cages that were frequently used to capture rice field eels were purchased, including 11 packaging tape-made cages, 7 plastic cages and 2 nylon rope-made cages. The eel-capturing activity was mimicked, and 20 ground cages were assigned in settings with relatively high (1.00 snail/0.1 m2 and higher) and low snail densities (< 1.00 snail/0.1 m2) in Xindai Township, Pinghu City, Zhejiang Province during the period from 15 : 00 to 8 : 00 of the following day on April 13, 26 and 28. The numbers of snails carried by different types of ground cages were compared in settings with different types of snail densities using the rank-sum test. Results A total of 11 cage-times were assigned in settings with a high snail density, and a total of 77 snails were captured, with a mean number of 7 snails in each cage-time and 2.15 snails in 0.1 m2 ground cage. The mean numbers of snails carried by packaging tape-made and plastic cages were 2.47 snails/0.1 m2 cage and 0.37 snails/0.1 m2 cage, respectively. A total of 24 cage-times were assigned in settings with a low snail density, and a total of 8 snails were captured, with a mean number of 0.33 snails in each cage-time and 0.09 snails in 0.1 m2 ground cage. The mean numbers of snails carried by packaging tape-made cages were 0.12 snails/0.1 m2 cage; however, no snails were carried by plastic or nylon rope-made cages. The number of snails carried by ground cages was higher in settings with a high snail density than in settings with a low snail density (Z = −4.019, P < 0.01), and the number of snails carried by packaging tape-made cages was higher in settings with a high snail density than in settings with a low snail density (Z = −4.086, P < 0.01). No significant differences were found in the numbers of snails carried by different types of ground cages. Conclusion The use of ground cage in snail habitats is a contributor to snail spread.

【Objective】 To develop a new approach for the preparation of 0.7~0.8 hematocrit concentrated washed red blood cells(RBCs) for fetal anemia in utero transfusion and apply it in clinical. 【Methods】 The erythrocyte suspension and frozen stored erythrocytes within expiry date in Guangzhou Blood Center from March 2020 to February 2021 were taken to prepare concentrated washed RBCs. According to the derivation formula, corresponding weight of RBC preservation solution was added to obtain 0.7~0.8 hematocrit concentrated washed RBCs. Routine blood test data were statistically analyzed by single-sample t test, and P<0.05 was considered statistically significant. Qualified Rh-negative/ O-type 0.7~0.8 hematocrit concentrated RBCs within expiry date were used in clinical intrauterine blood transfusion. 【Results】 The hematocrit of concentrated washing RBCs prepared by the new approach could reach 0.7~0.8. The RBCs count (8.389 ±0.808)×1 012/ L and hemoglobin content(233.730±15.498)g/L were higher while the erythrocyte count (0.732±0.469)×109 /L and platelets count(26.000±26.276)×109/L were lower than the normal values of adults. The mean erythrocyte volume(fL), hemoglobin content(pg) and concentration(g/L )were 88.123±6.359, 30.004±2.809 and 339.980±11.865, respectively, which were normal values of adults. Fetal anemia was significantly improved and the prognosis was good after intrauterine blood transfusion. 【Conclusion】 The 0.7~0.8 hematocrit concentrated washed RBCs prepared by the new approach is consistent with the special blood requirements during fetal anaemia transfusion, meets the clinical treatment standards, and can be applied in clinical.

To present the clinical characteristics and the misdiagnosis rate of acute coronary syndrome manifested primarily as throat discomfort, we conducted a multicentric and retrospective study in the cardiology and otorhinolaryngology departments. Records of patients with primary complaint of throat discomfort, absence of chest pain at onset, and an ultimate diagnosis of acute coronary syndrome, as well as patients with pharyngitis (as controls) were collected from May 2015 to April 2016. The patients' main manifestations were compared. Logistic regression results showed that chest tightness, dyspnea, perspiring, and exertional throat symptoms were significantly associated with acute coronary syndrome, with odds ratios of 8.3 (95% CI 2.2-31.5), 10.9 (95% CI 1.8-66.9), 25.4 (95% CI 3.6-179.9), and 81.2 (95% CI 13.0-506.7). A total of 25 (56.82%) out of 44 acute coronary syndrome patients, who were first admitted to the otorhinolaryngology department, were misdiagnosed, with a 12% (3/25) mortality rate. Throat discomfort can be the principal manifestation of acute coronary syndrome. Such patients exhibit high misdiagnosis and mortality rates. Exertional throat symptoms, chest tightness, perspiring, and dyspnea were important indicators of acute coronary syndrome in patients whose main complaint was throat discomfort. The awareness of this condition will result in prompt diagnosis and reduce morbidity and mortality.
