Objective:To explore the possibility of using a inferior gluteal artery perforator flap (IGAPF) for breast reconstruction in the patient who did not have suitable donor site in back and abdomen.Methods:In November 2024, a 25-year-old unmarried and childless woman with right breast cancer received immediate right breast reconstruction by a right free IGAPF after modified right mastectomy in the Department of Breast and Thyroid Surgery, Second Affiliated Hospital of Hainan Medical University. The locations of perforators were confirmed by both Multi-detector computed tomography angiography (MDCTA) and portable Doppler blood flow detector before surgery. The IGAPF was designed to take the inferior gluteal wrinkle as the lower edge, the axis of the flap was parallel to the inferior gluteal wrinkle, and the width of the flap was estimated where the incision could be directly closed. The size of right IGAPF was 6.0 cm×19.0 cm. Sharp dissection was performed between the sarcolemma and muscle fibres of gluteus, then the perforators were dissected along the direction of muscle fibres of gluteus. The vascular pedicle was kept at about 8.0 cm in length. The diameter of artery was about 2.0 mm and that for the veins was about 1.5 mm. End-to-end anastomoses with the right thoracodorsal artery and vein were successfully carried out. The donor site was directly closed, and it was hidden in the inferior gluteal wrinkle. Postoperative outpatient clinical review was made.Results:Pathological examination reported: an invasive carcinoma of right breast, axillary lymph node metastasis (2/10). The patient recovered well and the flap survived without any complication, i.e. ischemic necrosis, infection and haematoma. The patient was off-bed at 3 days and discharged at 13 days after surgery. At the 40 days of postoperative follow-up, the patient achieved a good recovery and the lower limb activity was not affected by the surgery. The patient was satisfied with the reconstructed breast and donor site recovery. The patient followed with scheduled chemotherapy and subsequent radiotherapy. The volume of reconstructed breast was smaller than the other breast, of which the patient was fully informed before the surgery.Conclusion:A free IGAPF provides an alternative donor sites for achieving a breast reconstruction due to the reliable pedicle vessels and invisible donor scars.

OBJECTIVE: To evaluate the clinical effect of "Tongdu Yisui" (unblocking the governor vessel and benefiting marrow) acupuncture and moxibustion on Meige syndrome. METHODS: Fifteen patients with Meige syndrome were treated with "Tongdu Yisui" acupuncture and moxibustion. Acupuncture was applied to Baihui (GV20), Dazhui (GV14), Shenzhu (GV12), Zhiyang (GV9), Jinsuo (GV8), bilateral Taixi (KI3), Zhaohai (KI6) and etc. Moxibustion was delivered at Jinsuo (GV8). After acupuncture and moxibustion at these body points, Jiao's scalp acupuncture was operated at bilateral chorea-tremor control area, and the patients were asked to walk for 20 min during needle retaining. Acupuncture and moxibustion were administered 20 min each time, once every two days, 3 times weekly and for 8 consecutive weeks. Assessments were conducted before treatment, after treatment, and follow-up at three months after treatment completion using the Burke-Fahn-Marsden dystonia rating scale (BFMDRS-M), abnormal involuntary movement scale (AIMS), and blepharospasm disability index (BSDI); and the clinical effect was evaluated after treatment. RESULTS: Compared before treatment, the scores of the sub-items of BFMDRS-M for eyes, mouth, speech and swallowing, and neck, as well as the total score of the scale, AIMS score and BSDI score decreased after treatment and during follow-up (P<0.05); the scores of the above indexes were not different statistically in comparison between the follow-up and after treatment (P>0.05). After treatment, 13 cases were effective, 2 cases were failed and the total effective rate was 86.7% (13/15). CONCLUSION "Tongdu Yisui" acupuncture and moxibustion can effectively alleviate motor symptoms and dysfunction of Meige syndrome and presents the sustained therapeutic effect.

In order to understand the prevalence and genetic variation of H9N2 subtype avian influ-enza virus in Shandong,a total 492 tracheal and lung tissue samples collected from chicken farms with respiratory symptoms in partial areas in Shandong were detected by H9 subtype AIV real-time RT-PCR,and the positive samples were inoculated with chicken embryos for two generations.Whole genome sequences of the positive strains by applying Illumina Miaseq platform,and genetic evolution and mutation at positions associating with viral pathogenicity and transmissibility were analyzed.The results showed that there were 72 samples were positive for H9 subtype AIV among the 492 samples,with a positive rate of 14.63％.Thirty-four strains of H9 subtype AIV were ob-tained from the positive samples after passing through chicken embryo,meanwhile,the 34 isolates were all H9N2 subtype AIV by whole genome sequencing analysis.By analyzing the evolutionary tree of HA and NA genes,HA and NA genes of the 34 H9N2 AIV strains belonged to Y280-like branch and F/98-like branch,respectively.Meanwhile,based on above branches,there were obvious time node subbranch,which one was"isolates before 2013",another one was"isolates after 2013".The HA cleavage sites of thirty-four H9N2 strains were all 325PSRSSR↓GLF333,which met the se-quence characteristics of the lowly pathogenic avian influenza virus,and the HA receptor binding site 226 amino acid was leucine,which had the characteristics of blinding to a-2,6 mammalian sialic acid receptors.Among the internal amino acid sites that are key to mammalian adaptation,all strains had an I368V mutation in the PB1 gene that enhanced viral transmissibility in mammals and the PB2 genes of some strains were mutated to enhance the mammalian adaptation of I292 V and A588 V.The above results illustrated that the H9N2 subtype AIV gene segments in Shandong have different degrees of recombination and gene variation,so it is necessary to strengthen the monito-ring of virus variation.

OBJECTIVE To explor e the characteristics of spectral oscillatory power of resting-state electroencephalography(EEG) in subjective tinnitus patients and to lay the foundation for study of central mechanism of tinnitus.METHODS 31 subjects(15 subjects with subjective tinnitus and 16 age matching healthy subjects) underwent a 128-channel resting-state EEG analyses. After a series of preprocessing, data were segmented into 8 frequency bands, including δ(0.5～3.5 Hz), θ(4～7.5 Hz), α1(8～10 Hz), α2(10～12 Hz), β1(13～18 Hz), β2(18.5～21 Hz), β3(21.5～30 Hz) and γ(30.5～44 Hz). The group differences of spectral power were analyzed by independent t test. Correlation between spectral power of each frequency band and tinnitus subjective symptoms were also analyzed. RESULTS Significant higher spectral power of the α1, β and γ bandwere found in the left and right temporal areas of tinnitus group compared with that of normal group.Tinnitus subjects also had higher spectral powerof the δ and θ band in temporo-parietal areas than that of the normal group. There was no significant difference of spectral power in other frequency bands. Moreover, signif icant positive cor relation were found between tinnitus loudness and spectralpower of right anterior lateral(R=0.66, P =0.007) and right anterior medial(R=0.58, P =0.031) areas. CONCLUSION Tinnitus subjects have higher spectral oscillatory power on right and left temporal lobe and temporo-parietal area. A positive correlation exsit between tinnitus loudness andspectral power of right anterior lateral and medial areas in tinnitus subjects, whichindicate that central reorganizationexsit in tinnitus reorganization andγ band maybe considered as a possible biomarkerforthe tinnitus subjective symptom.

Objective To investigate the relationship between serum anticardiolipin antibody-immune globulin G (ACA-IgG),interleukin-10 (IL-10 ),IL-17 levels and intracranial large-artery atherosclerotic stenosis in patients with ischemic stroke. Methods From March 2014 to March 2015,a total of 176 consecutive patients with the first-ever ischemic stroke admitted to the Department of Neurology,Liaocheng People′s Hospital,Shandong Province,China,and performed DSA were enrolled prospectively. Seven of the patients with cardiogenic embolism,5 with moyamoya disease,8 with arteritis,2 with artery dissection,9 with autoimmune diseases or acute and chronic inflammation were excluded,21 with extracranial arterial stenosis were not enrolled,and finally 124 were enrolled in the study. According to the findings of DSA,the degrees of intracranial large artery stenosis were divided into a stenosis-free group (n = 34),a mild-stenosis group (n = 30),a moderate-stenosis group (n = 32),and a severe-stenosis group (n = 28). The differences of serum ACA-IgG,IL-10,IL-17 levels and baseline factors of the 4 groups were compared,and multivariate logistic regression analysis was used to analyze several factors that affected intracranial large-artery stenosis. Results There were no significant differences in sex,age,alcohol consumption rate,smoking rate,and incidence of hyperlipidemia among the 4 groups of patients (all P >0. 05). Compared with the stenosis-free group,there were significant differences in the incidences of hypertension and diabetes among the mild-stenosis,moderate-stenosis and severe-stenosis groups (the incidence of hypertension,80. 0% [n = 24],93. 8% [n = 30],89. 3% [n = 25]vs. 55. 9% [19 cases];χ2 = 8. 271,8. 920,and 10. 877,respectively;P = 0. 038,0. 032,and 0. 014,respectively). The incidences of diabetes were 33. 3% (n = 10),43. 8% (n = 14),60. 7% (n = 17)vs. 8. 8% (n = 3),(χ2 = 7. 960, 8. 733,and 9. 285,respectively;P = 0. 043,0. 035,and 0. 027,respectively). Incidence of diabetes of the severe-stenosis group was higher than that of the mild-stenosis group (χ2 = 9. 348,P = 0. 025). There were no significant differences in the incidences of hypertension and diabetes among other groups (all P >0. 05). There were significant differences in ACA-IgG levels (23 ± 5,39 ± 8,51 ± 9,and 65 ± 10 kU/ L);IL-10 levels (108 ± 33,85 ± 25,77 ± 21,and 62 ± 19 ng/ L),and IL-17 levels (38 ± 10,58 ± 22,63 ± 31, and 75 ± 26 ng/ L)among the stenosis-free,mild,moderate and severe-stenosis groups (F = 17. 754,9. 827, and 12. 656;respectively;all P < 0. 01). Compared with the stenosis-free group,the ACA-IgG and IL-17 levels of the patients in the mild,morderate,and severe stenosis groups increased significantly (ACA-IgG level:t =2. 307,2. 559,and 3. 374,respectively;P = 0. 026,0. 014,and 0. 001,respectively,the IL-17 levels:t =2. 183,2. 549 and 3. 159,respectively;P = 0. 037,0. 013,and 0. 002,respectively),while the IL-10 level decreased significantly. There were significant differences among the groups (t = 2. 036,2. 351,and 2. 762, respectively;P = 0. 042,0. 023,and 0. 006,respectively). Compared with the mild-stenosis group,the ACA-IgG and IL-17 levels of the severe stenosis group increased significantly (t = 3. 154 and 2. 976 respectively;P = 0. 002 and 0. 004 respectively). There were no significant differences among the pairwise comparisons of other groups (P >0. 05). The results of logistic regression analysis showed that hypertension, diabetes,ACA-IgG level,and IL-17 level were the risk factors for intracranial large-artery stenosis (OR, 3. 043,95% CI 1. 606 -5. 875,P = 0. 003;OR,2. 912,95% CI 1. 513 -5. 824,P < 0. 01;OR,1. 837,95% CI 2. 057-3. 416,P = 0. 037;OR,1. 453,95% CI 1. 346 -2. 721,P = 0. 014). Conclusion ACA-IgG and IL-17 may play an important role in the occurrence and development processes of intracranial large-artery atherosclerotic stenosis.

Objective To explore the effect of Shugan Lifei prescription on expression of Transforming Growth Factor-beta1(TGF-β1) and Smad3 in asthma rats under chronic stress condition. Method The 40 SD rats were randomly divided into four groups:control group, model group, dexamethasone group and Shugan Lifei group. Asthma model was established by inhaling atomized ovalbumin (OVA) passively and experiencing chronic unpredictable mild stress (CUMS). From the 15th day of modeling, the treatment groups were intervened with dexamethasone drugs and Shugan Lifei prescription. Lung pathomorphology was observed via HE staining. The expressions of TGF-β1 and Smad3 in lung tissue were measured by immunohistochemical and RT-PCR. Results Compared with control group, the wall area and the smooth muscle area in the model group significantly increased. While compared with asthmatic model group,the wall area and the smooth muscle area in the dexamethasone group and Shugan Lifei group were significantly lower. Immunohistochemistry and RT-PCR showed that in comparison with control group , the expression of TGF-β1/Smad3 protein and mRNA in lung tissues in the model group significantly increased(P<0.05), while the TGF-β1/Smad3 protein and mRNA in lung tissues in the dexamethasone group and Shugan Lifei group were detected to be significantly lower than model group (P<0.05). Conclusion Shugan Lifei method could improve airway remodeling in asthma rats under chronic stress condition , and this result is possibly achieved by reducing TGF-β1 and Smad3 expression levels.

Objective To evaluate the robustness of body mass index (BMI) adapted tube current selection method for obtaining consistent image quality in MSCT coronary artery imaging Methods Initially one hundred patients in the control group ( C group) underwent cardiac scans using GE 64-row VCT with standard scan protocol (640 mA, 120 kV, 0.35 see, body bewtie, C2 filter). Noise measurement was obtained for each patient using the average of three consecutive slices in the ascending aorta with ROI of 10 mm×10 mm to establish the relationship between BMI, desired image noise (IN) and required mA. An excel table was established to predict the required mA to achieve a desired IN for each patient with different BMI. A second group of one hundred cardiac patients (L group) was scanned with BMI-aclapted mA from the table to evaluate the practicability of this method. BMI, IN, CT dose index(CTDI),effective dose (ED) were all recorded. Results For the control group of 100 patients, the mean values and standard deviations of image quality score (IQS), BMI, IN and ED were 3.71±0.54, 25.08±2.63, 24.56±5.03 and (17.63±1.68 ) mSv (with range of 15-22 msy). Regression analysis indicated linear relationship between BMI and image noise with fixed mA. Using the relationship between tube current and image noise and noise ratio between large bowtie and cardiac bowtie, the following equation for the required tube current Xma to achieve present image noise of Ins for patient with certain BMI value when using cardiac bowtie could be then obtained: Xma = Fma×( k1 x BMI + c1 )/Ina]2, where Fma = 640 mA, k1 = 1. 033, c1 = - 3.2, Ins = 27 in the study. (2) For the patients in L group, the mean values and standard deviations of IQS, BMI, and IN were 3.69±0.53, 25.07±2.91, and 26.61±3.44, respectively. The average tube current used was (469.95±113.45) mA, depending on patient's BMI values. The average effectively dose was(9.08±2.25) mSv. There was no statistically difference between the two groups in image quality( F= 0.068,P=0.794). Conclusions In 64-MSCT cardiac imaging, the use of BMI dependent tube current selection method, in conjunction with dose reduction techniques, can provide individualized scan protocol to obtain consistent image quality across patient population and to optimize dose delivery to patients.

Objective To investigate the effects of tumor necrosis factor ? (TNF ?) on ? adrenoceptor (? AR) and ? AR related G protein coupled receptor kinases (GRKs) in rat pulmonary microvascular endothelial cells (PMVECs) as well as the interfering action of anisodamine. Methods Radio ligand binding assay was used to measure the maximal binding capacity (B max ) changes of ? AR in rat PMVECs after treatment with TNF ?. The effects of TNF ? and ? AR related GRKs expression at the protein level were observed by Western blotting. Results B max of ? AR in normal rat PMVECs was (5.58?0.31) fmol/10 5 cells. B max of ? AR in TNF ? group decreased significantly as compared with that in the normal control group, but no significant difference was found between the normal control group and TNF ?+anisodamine group. The expression of GRK2 in rat PMVECs was positive, but expression of GRK3, GRK5, and GRK6 were negative. The expression of GRK2 in TNF ? group and TNF ?+anisodamine group increased significantly as compared with that in the normal control group, but no significant difference was found between the TNF ? group and the TNF ?+anisodamine group. Conclusion GRK2 but not GRK3, GRK5, or GRK6 is expressed in rat PMVECs. The increased expression of GRK2 induced by TNF ? in rat PMVECs might promote the phosphorylation of ? AR, leading to ? AR internalization and decoupling with G protein, which might be the main mechanism of down regulation of ? AR induced by TNF ?. Anisodamine might inhibit the down regulation of ? AR through other mechanism instead of inhibiting the increase of GRK2 expression.
