Good result was achieved in 159 cases including excellent in 96 and fair in 63, surgery was ineffective in 30 cases. Six cases(3 2%) died of surgery related complications during the long term follow up. In the first week after operation platelet counts reached 100?10 9/L in 118 cases, among them 110 cases(69 2%) fell into effective group and 8 cases(26 7%) fell into ineffective group( ? 2= 19 45, P

Objective To assess the val ue of 18-fluorodeoxy glucose (~18F-FDG) positron emission tomography( PE T)-CT in the detection of malignant bone metastases. Methods Thirty-five out of 332 patients, 89 lesions were detected on ~18 F-FDG PET-CT and were interpreted separately on PET, combined CT, and fused PE T-CT images. Results Of the 89 lesions detected on PET- CT images, 68 were malignant and 21 were benign lesions. PET alone identified 62 malignant lesions and 17 benign lesions. The diagnostic sensitivity, specificit y, and accuracy of PET alone for diagnosis of bone metastases were 91.2% (62/68) , 81.0% (17/21), and 88.8% (79/89), respectively. The combined CT alone identifi ed 55 malignant lesions and 16 benign lesions. The diagnostic sensitivity, s pecificity, and accuracy of combined CT alone were 80.9% (55/68), 76.2% (16/21), and 79.8% (71/89), respectively. The fused PET-CT images identified 64 maligna nt and 19 benign lesions. The diagnostic sensitivity, specificity, and accuracy of the fused PET-CT were 94.1% (64/68), 90.5% (19/21), and 93.2% (83/89), respe ctively. Conclusion In the diagnosis of bone metastases, ~18F-FDG PET-CT imaging reduces the false positive rate and increases the specificity. ~18F-FDG PET-CT imaging is helpful in the differentiation o f bone metastases from benign lesions.

Objective To observe the therapeutic effect of hoop circumference drug,Hongzhongxiao tincture,on the treatment of skin abscess in rats under the guidance of defended field theory.Methods Forty SpragueDawley (SD) rats were randomly divided into normal control group,model group,western medicine control group,Hongzhongxiao pretreatment group and Hongzhongxiao treatment group according to the computer generated random number.Subcutaneous abscesses models were reproduced by subcutaneous injection of 1 mL (3-5 × 109 cfu/mL) of staphylococcus aureus,and the normal control group was subcutaneously injected with the same amount of normal saline.After molding,the rats in the model group were treated with normal saline for change of dressing;the western medicine control group was treated with mupirocin ointment for external use;Hongzhongxiao pretreatment group was treated with 2 mL of Hongzhongxiao for dressing 4 hours after the modeling;in Hongzhongxiao treatment group,2 mL dressing was given after the emergence of hard swelling,and the Hongzhongxiao drug range applied was 1 cm over the swelling range.Each group was dressed once daily.The changes of mental state,body weight,skin temperature,range and time of abscess formation,wound ulceration and healing time,transcutaneous oxygen pressure (TcPO2) at the periphery of abscess were observed in each group.Results ① After modeling,the activity of the rats was decreased,the appetite became worse,and the food intake less.Except the normal control group,the rats in other groups had different degrees of mental listlessness.② After 3 days of treatment,the body weight gain of the model group was significantly lower than that of the normal control group (g:8.75 ± 9.85 vs.31.67 ± 7.92,P ＜ 0.01),and continued to 18 days after treatment (g:27.13± 11.70 vs.98.00 ± 8.94);after treatment for 18 days,the body weight gain in the western medicine control group,Hongzhongxiao pretreatment group and Hongzhongxiao treatment group was significantlyhigher than those of model group (g:53.28 ± 19.69,49.12 ± 7.23,44.71 ± 12.42 vs.27.13 ± 11.70,all P ＜ 0.05).③ After 3 days of treatment,the body temperature of the model group was obviously lower than that of the normal control group (℃:33.75 ± 0.68 vs.35.03 ± 0.41,P ＜ 0.01) and continued to 10 days (℃:34.30 ± 0.35 vs.35.03 ± 0.41,P ＜ 0.01).The body temperature of the rats in Hongzhongxiao pretreatment group was significantly lower than that in the normal control group,the model group and the western medicine control group on the 14th day after treatment (℃:33.97 ± 0.83 vs.35.10 ± 0.57,35.01 ± 0.68,35.25 ± 0.23,all P ＜ 0.05).The body temperature of Hongzhongxiao treatment group was significantly higher than that of the Hongzhongxiao pretreatment group (℃:34.87 ± 0.94 vs.33.97 ± 0.83,P ＜0.05).④ After treatment for 13,15,17 days,the contraction rates of swollen area in western medicine control group,hongzhongxiao pretreatment group and hongzhongxiao treatment group were greater than the rate in model group,and the change was most significant on the 17th day after treatment [(96.37 ± 5.09)％,(92.76 ± 13.56)％,(98.41 ± 3.85)％ vs.(77.46 ± 19.07)％,all P ＜ 0.05].⑤ Compared with the model group,the times of abscess localization in the western medicine control group,the Hongzhongxiao pretreatment group and the Hongzhongxiao treatment group was shorter than that in the model group (days:9.28 ± 1.38,7.33 ± 1.97,7.67 ± 1.63 vs.12.63 ± 1.99,all P ＜ 0.05);the time of wound healing in Hongzhongxiao pretreatment group aud Hongzhongxiao treatment group were significantly shorter than those of the model group (days:17.67 ± 1.03,16.83 ± 1.51 vs.19.92 ± 2.33,P ＜ 0.05).⑥ TcPO2 in the Hongzhongxiao pretreatment group was significantly higher than that in the model group on the 7th day after treatment [mmHg (1 mmHg =0.133 kPa):63.33 ± 9.77 vs.39.51 ± 8.42],and the Hongzhongxiao treatment group (44.25 ± 6.41) was significantly lower than that of the Hongzhongxiao pretreatment group,and the Hongzhongxiao treatment group was significantly higher than that of the model group (59.50 ± 7.34 vs.49.52 ± 10.17) on the 14th day after drug application,and the western medicine control group was significantly lower than that of the model group (37.71 ± 5.63 vs.54.33 ± 7.74),the Hongzhongxiao pretreatment group and Hongzhongxiao treatment group were significantly higher than those of the western medicine control group,the difference being statistically significant (all P ＜ 0.05).Conclusions The Hongzhongxiao tincture applied on top and circumferentially around the periphery of the abscess can reduce the local inflammatory response,improve the body weight and mental state,increase the blood supply around wound periphery for anti-infection and anti-inflammation in order to promote the formation of defending field of nursing.Although the early application of Hongzhongxiao tincture cannot reduce the local infectious symptoms and kill the Staphylococcus aureus,it can make skin abscess localization as soon as possible and shorten the wound healing time.

Objective To investigate the association between the single nucleotide polymorphism (SNP) of leukotriene C4 synthase(LTC4S) rs730012 in the childhood asthma.Methods Sequence specific primers-polymerase chain reaction was used to assess the genetic polymorphism of LTC4S rs730012 in 105 asthma children with different order of severity and 128 non-asthma children in our hospital in the northeast of China to analyse the association between the SNP of LTC4S rs730012 and susceptibility,clinical phenotype in asthma children.Results (1) In case group,genotype frequencies of A/C,A/A and C/C were 71.4％ 、25.7％ 、2.9％,allele frequencies for A,C were 84.3％,15.7％.In control group,the genotype frequencies of A/A,A/C,C/C,were 70.3％,28.9％,0.8％,allele frequencies for A,C were 84.8％,15.2％.No significant difference was found in AA genotype and C allele frequencies between case and control grouP(x2 =0.035、0.020,P both ＞0.05).(2) C/C genotype or C allele frequencies in moderate-severe asthma group were significantly higher than the mild asthma group(x2 =5.859、5.641,P both ＜ 0.05);(3) SaO2 of A/A group was significantly higher than A/C and C/C group (t =2.976,Pboth ＜ 0.05),and FeNO and obstructive ventilatory disorder incidence rate in A/C,C/C group were higher than A/A group,the differences were statistically significant (t =2.946、x2 =5.564,P both ＜ 0.05).Conclusion The SNP of LTC4S rs730012 is associated with the order of severity,SaO2,FeNO,pulmonary function in asthma children of northeast China.However,the rs730012 is not associated with the susceptibility for asthma.

Objective:To compare the efficacy of radial forearm flap and anterolateral thigh flap in repairing soft tissue defects after oral cancer surgery and to explore their indications.Methods:A retrospective analysis was conducted on clinical data of patients with oral cancer treated at the Department of Stomatology, Affiliated Hospital of Nantong University, from May 2019 to February 2023. Patients were divided into two groups based on the repair method: the radial forearm flap group and the anterolateral thigh flap group. The groups were compared in the following aspects. (1) Surgical parameters including defect area after oral cancer resection, flap area, flap preparation time, operation time, and length of hospital stay. (2) Inflammatory markers (interleukin-6 and C-reactive protein levels) measured 1 day before surgery and 1 day after surgery. (3) Flap survival rate was calculated. (4) Complication rates was calculated in the flap donor area and infection rates in the oral recipient area within 6 months postoperatively. (5) Six months postoperatively, the patient’s oral function was assessed by a physician using the University of Washington quality of life scale (UW-QOL). The evaluation included assessments of oral opening, speech, and eating functions. Each parameter was scored on a scale of 0 to 10 (higher scores indicated better recovery). (6) Quality of life was assessed using the 36-item short form health survey scale(SF-36) at 2, 4 and 6 months postoperatively, with scores ranging from 0 to 100 (higher scores indicated better quality of life). (7) Patient satisfaction was assessed at 6 months postoperatively, with satisfaction levels categorized as satisfied, basically satisfied, and dissatisfied. The satisfaction rate was calculated as (satisfied + basically satisfied ) cases / total cases in each group × 100%. Statistical analysis was performed using SPSS 22.0. Measurement data were expressed as Mean±SD, and comparisons between groups were conducted using t-tests. Count data were expressed as cases and (or) percentages, and comparisons were made using chi-square test. P<0.05 was considered statistically significant. Results:The radial forearm flap group included 48 cases (32 males, 16 females), aged (49.3±5.0) years, with a body mass index (BMI) of (23.0±1.1) kg/m 2 and a disease course of (6.5±2.1) months. The group had 21 cases of tongue cancer, 12 of floor of mouth cancer, and 15 of buccal cancer, including 40 squamous cell carcinomas and 8 basal cell carcinomas. The anterolateral thigh flap group included 32 cases (20 males, 12 females), aged (50.1±5.0) years, with a BMI of (23.0±1.0) kg/m 2 and a disease course of (7.0±2.2) months. The group had 16 cases of tongue cancer, 7 cases of floor of mouth cancer, and 9 cases of buccal cancer, including 27 squamous cell carcinomas and 5 basal cell carcinomas. There were no significant differences in gender, age, BMI, disease course, tumor location, or pathological type between the two groups ( P>0.05). The defect area after oral cancer resection was smaller in the radial forearm flap group[ (39.0±1.3) cm 2 ] compared to the anterolateral thigh flap group[ (40.3±2.2) cm 2] ( t=3.32, P=0.001). There were no significant differences in flap area, flap preparation time, or length of hospital stay between the two groups ( P>0.05). The operation time was shorter in the radial forearm flap group [(5.1±1.1) h] compared to the anterolateral thigh flap group [(6.8±2.8) h] ( t=0.26, P<0.001). There were no significant differences in interleukin-6 and C-reactive protein levels between the two groups 1 day before surgery and 1 day after surgery ( P>0.05). The flap survival rates were 97.9% (47/48) in the radial forearm flap group and 93.8% (30/32) in the anterolateral thigh flap group, with no significant difference( P>0.05). Postoperative donor site complications mainly included infection, pigmentation, itching, etc. The overall incidence of complications in the donor site of the radial forearm flap [33.3% (16/48)] was higher than that in the anterolateral thigh flap group [12.5% (4/32)], and the difference was statistically significant ( χ2=4.44, P=0.035). There was no significant difference in infection rates in the oral recipient area between the two groups ( P>0.05). Six months postoperatively, the average scores for oral opening, speech, and eating functions were above 7 in both groups, with no significant differences ( P>0.05). Quality of life scores improved over time in both groups, with average scores above 90 at 6 months postoperatively, and no significant differences at any time point ( P>0.05). The patient satisfaction rate was 91.7% (44/48) in the radial forearm flap group and 90.6% (29/32) in the anterolateral thigh flap group, with no significant difference ( P>0.05). Conclusion:Both radial forearm flap and anterolateral thigh flap can effectively repair soft tissue defects after oral cancer resection, significantly improving patients’oral function. The anterolateral thigh flap provides sufficient tissue volume and is suitable for patients with larger defect areas. The radial forearm flap is suitable for patients with a smaller defect area after oral cancer resection. Its surgical procedure is relatively less complex and offers an advantage in reducing surgery time. However, the donor site complications are higher with the radial forearm flap compared to the anterolateral thigh flap.
