Objective:To observe any effect of extracorporeal shock wave therapy (ESWT) on patients with moderate to severe breast cancer-associated lymphedema (BCAL) with skin fibrosis and upper limb symptoms receiving complex decongestive therapy (CDT).Methods:Forty patients with moderate to severe breast cancer-associated lymphedema were randomly divided into an ESWT+ CDT group and a CDT group, each of 20. Both groups received manual lymph drainage, 5 times per week for 4 weeks with short elastic bandages or compression cuffs. The ESWT+ CDT group was additionally provided ESWT (2.0 bar, 5 Hz, 2500 pulses) twice a week for 4 weeks. Limb swelling, skin fibrosis and symptoms of lymphedema were assessed using the circumference measurement method, modified Rodnan skin scores (mRSSs), and the Breast Cancer and Lymphedema Symptoms Experience Index (BCLE-SEI) before the treatment and after 2 and 4 weeks.Results:After 2 weeks the limb volume, skin sclerosis and lymphedema symptoms of both groups had improved significantly, with the average limb volume, mRSS score and BCLE-SEI score of the ESWT+ CDT group significantly better than those of the CDT group. After 4 weeks of treatment, the limb volume, skin sclerosis and lymphedema symptoms further improved in both groups with the ESWT+ CDT group again showing significantly greater improvement.Conclusion:ESWT can further accelerate the recovery of patients with lymphatic edema after breast cancer surgery receiving CDT therapy, correct the cycle of skin fibrosis and lymphedema, and relieve complications such as limb pain. It is worthy of clinical promotion and application.

OBJECTIVETo study the feasibility and effect of substituting esophagus with stomach or colon without thoracotomy in the treatment of cervical esophageal carcinoma with laryngeal function preserved.

METHODSTwenty-four patients with cervical esophageal carcinoma were retrospectively reviewed. The esophagus was resected and substituted with 19 gastric pull-up and 5 colon interposition. Nineteen patients received radiotherapy postoperatively (dose 50 - 70 Gy).

RESULTSTwenty two patients were follow up over 3 years. The 3- and 5-year survival rates for T2 were 3 and 1, for T3, T4 8 and 3, respectively. The laryngeal function preservation rate was 77% (17/24) and the decannulation rate was 75% (12/16). The complication rate was 29%.

CONCLUSIONSurgical resection of cervical esophageal carcinoma with removal of the extraesophageal invaded tissues while preserving the laryngeal function is possible. The continuity of the esophagus is restored by stomach transposition and colon interposition. Combined with radiotherapy, the survival rate and life quality of the patient might be improved.

This study was aimed to investigate the application value of the dual color dual fusion fluorescence in situ hybridization (DCDF-FISH) in BCR/ABL (+) acute lymphoblastic leukemia patients with complex chromosomal translocation. The clinical presentations of a patient with ALL were monitored regularly by bone marrow cell morphology test, chromosome analysis, flow cytometry and DCDF-FISH technique, and the reaction of patients to treatment and disease progression were dynamically observed by DCDF-FISH. The results indicated that the patient showed the typical presentation of B lineage acute lymphoblastic leukemia (B-ALL) with expression of CD10, CD19 and CD34; the chromosome analysis showed 46,XY, i(8), ider(9)t (9; 22) [23]/47, idem, +der(22) t (9;22) [7] karyotype in the bone marrow cells, FISH showed that 83% cells contained BCR/ABL fusion gene in the patient's bone marrow, among which 5% cells showed 1R1G2F signalling model, 14% cells showed 1R1G3F, and 64% cells showed 1R1G4F. The patient got complete remission when the imatinib chemotherapy combined with VTLP was carried out, and the tumor cells decreased to 19%, but the cells with 1R1G2F signal model increased to 18%. The 1R1G2F cell signal model increased up to 38% when patient relapsed. The patient died of the drug-resistance. It is concluded that the BCR/ABL (+) leukemia patient with complex translocation has multiple tumor cell subsets, and the responses of different cell subsets to the treatment are different, therefore the response to therapy and drug resistance of patient can be monitored early by the signal model of DCDF-FISH and the observation of dynamical changes of different cell subset.

To investigate the potential hypoglycemic effect of nanosuspensions of honokiol and explore the underlying mechanisms, a high fat diet (HFD) was studied in C57BL/6J mice divided into five groups: normal diet (ND), HFD, HFD/honokiol-sodium carboxymethyl cellulose (CMC-Na) (Hono-CMC, 100 mg·kg^-1), HFD/honokiol- Nano (Hono-Nano, 80 mg·kg^-1), HFD/metformin (HFD/Met, 200 mg·kg^-1). Fasting blood glucose (FBG) and body weights (BW) of mice were measured every seven days. After 30-day treatment, an oral glucose tolerance test (OGTT) was performed, and blood and tissue samples were collected for analysis. All animal experiments were approved by the Research Animal Care Committee of Affiliated Hospital of Integrated Traditional Chinese and Western Medicine, Nanjing University of Chinese Medicine. The data showed Hono-Nano and metformin reduced FBG, BW, and markedly improved OGTT of mice compared to HFD group (P<0.05). Hono-CMC produced nonsignificant impact on FBG, BW of mice, while OGTT of mice was improved by Hono-CMC (P<0.05). Meanwhile, none of these treated groups showed significant effects on regulating serum insulin levels, but all of them exhibited decreased serum glucagon levels notably compared to the HFD group (P<0.05). Western blot analysis revealed that honokiol up-regulated levels of p-AMPK and p-FOXO1 in liver tissue of HFD mice (P<0.05), which resulted in activation of AMPK and inhibition of FOXO1. Moreover, the expression of PEPCK (a key enzyme of gluconeogenesis) was decreased by honokiol (P<0.05). Taken together, our findings demonstrate that nanosuspension of honokiol is more effective than CMC-Na-suspension of honokiol on blood glucose controlling in HFD mice. The hypoglycemic effects of honokiol might rely on suppressing hepatic gluconeogenesis via activating AMPK and inhibiting FOXO1.

OBJECTIVE: To evaluate the effect of sonication, repeated freeze-thaw cycles, calcium salt solution and their combination on the content of related growth factors (GFs) released by platelet rich plasma (PRP). METHODS: Twenty PRPs from healthy blood donors were divided into 9 groups, including sonication group, freeze-thaw group, calcium gluconate group, calcium chloride group, sonication + calcium gluconate group, sonication + calcium chloride group, freeze-thaw + calcium gluconate group, freeze-thaw + calcium chloride group, and sonication + freeze-thaw group. After PRP activated by above 9 methods, the content of transforming growth factor-β1 (TGF-β1), vascular endothelial growth factor (VEGF), and platelet-derived growth factor-BB (PDGF-BB) were detected by ELISA. RESULTS: The platelet concentration of the samples was (966.7±202.6)×10⁹/L. The content of TGF-β1 in sonication + freeze-thaw group was the highest, while the lowest was in freeze-thaw group. The content of VEGF in freeze-thaw + calcium chloride group was the highest, while the lowest was in calcium gluconate group. The content of PDGF-BB in sonication + freeze-thaw group was the highest, while the lowest was in calcium gluconate group. There was no significant differences in the three GFs between calcium gluconate group and calcium chloride group. CONCLUSION Among the 9 activated methods of PRP, there is no difference between two calcium salt solutions. And the combination of repeated freeze-thaw cycles and sonication may be the best treatment method to promote PRP to release GFs, while calcium gluconate is the weakest way.

OBJECTIVE: To evaluate the tooth loss status of mandibular molars with furcation involvements after 5-year non-surgical periodontal treatment, and to analyze the factors that affected the tooth loss. METHODS: A retrospective analysis was conducted in 79 patients with chronic periodontitis, who had received non-surgical periodontal treatment and 5 years of periodontal maintenance treatment in Department of Periodontology, Peking University School and Hospital of Stomatology from 1988 to 2012. Their clinical indexes, including probing depth (PD), bleeding index (BI), furcation index (FI) and tooth mobility were both evaluated before treatment and at the last time of the maintenance treatment. Bone resorption at furcation area was measured at the first visit by periapical radiographs taken by professional doctors of medical imaging. The status of tooth loss after 5-year non-surgical periodontal treatment on mandibular molars with furcation involvement, and the factors that affected the tooth loss were analyzed. RESULTS: (1) Non-surgical treatment was significantly effective on the changes of PD in the patients of chronic periodontitis with furcation involvement, while the presence of furcation involvement could affect the improvement of PD here. (2) PD at the furcation area, tooth mobility, vertical bone resorption, and bone resorption area were all significant risk factors of mandibular molar missing (P<0.001), and the same with FI=3 and FI=4 (P=0.017, P=0.007), while age (P=0.703), gender (P=0.243) and smoking history (P=0.895) were not related to the tooth loss in this study. (3) The risk of tooth loss in mandibular molars with FI≥3 were significantly higher than those with FI≤2, and the survival rate of the former was less than 50%. CONCLUSION The loss of mandibular molars with furcation involvement was related to the furcation involvement, meanwhile the degree of furcation involvement and bone resorption can significantly increase the risk of tooth loss.

Objective: A multicenter Chinese mainland survey was conducted to investigate the sensitization distribution characteristics of cat, dog and horse dander in patients with allergic diseases, so as to provide clinicians with epidemiological data of common animal allergens and useful information for the prevention and treatment of allergies in cats, dogs and horses. Methods: The epidemiological investigation and design was adopted. This study is based on the national epidemiological survey of allergic diseases led by the first affiliated Hospital of Guangzhou Medical University. From January to December in 2021, a total of 2 122 patients diagnosed with allergic diseases were included in the outpatient department of respiratory department/pediatrics/allergy department of 14 units such as the First Affiliated Hospital of Guangzhou Medical University, and 222 healthy subjects were included as controls from the physical examination center of the above units in the same period. All the subjects filled out the allergic disease questionnaire under the guidance of doctors, and the allergen-specific immunoglobulin E (sIgE) of cats, dogs and horses of all subjects were detected by magnetic particle chemiluminescence system. The epidemiological characteristics of three animal allergens in different diseases, ages and regions were analyzed. Chi square test was used to analyze the frequency difference between groups, t test or Mann Whitney U test was used to test the distribution difference between two groups, and one-way ANOVA or Kruskal Wallis H test was used to compare the distribution difference between multiple groups. Bar chart, Venn-plot and radar chart were drawn to show the sensitization distribution characteristics. A small number of missing values caused by subjects' omission have been excluded during the analysis. Results: The 2 122 patients with allergic diseases were 57.35% male (1 217/2 122) and 40.95% female (869/2 122), and 1.70% (36/2 122) patients had loss of gender information. The age of patients with allergic diseases was 9.0 (6.0, 28.0) years, while that of healthy controls was 29.0 (13.0, 39.0) years old, and there were 1.7% (36/2 122) and 0.9% (2/222) subjects with missing age information, respectively. The proportion of caesarean section in allergic patients was significantly higher than that in healthy controls (31.4% vs. 17.6%,χ²=16.582,P<0.001) [2.5% (54/2 122) of the patient group and 5.4% (12/222) of the control group had missing birth mode information], and the proportion of patients with allergic diseases who reported that both parents had allergic diseases was significantly higher than that of the control group (35.7% vs. 9.5%, χ²=65.171,P<0.001). Patients with allergic diseases are mainly school-age (6-12 years old) and adolescents (12-18 years old). 16.4% of patients with allergic diseases were sensitized to cat dander, 10% and 6% to dog and horse dander. The sensitization rate of cat dander in patients with rhinitis, asthma, conjunctivitis, food allergy and atopic dermatitis was the highest (16.4%-21.6%), followed by dog dander (10.2%-15.2%). The prevalence of allergic rhinitis was the highest among different animal sensitized populations. The proportion of cat, dog and horse allergens sensitized at the same time is between 10%-15%, and the proportion of any two or more animal dander sensitized at the same time is about 45%. Animal allergens are associated with respiratory allergic diseases, especially allergic rhinitis with allergic conjunctivitis. There were significant differences in the distribution of positive rates of three animal allergens in different regions, and the highest positive rate of cat dander was found in all provinces of the country. Conclusion: The sensitization rate of animal dander allergens increased significantly, and the highest was in children and adolescents. Cat dander is the most common animal allergen, followed by dog. Different animals show obvious cross or common sensitization due to their high homology.
