Objective To access the clinical value of interstitial brachytherpay in patients with advanced carcinoma. Methods 6 patients(1 case of hepatic cancer,3 cases of prostate cancer,2 cases of local recurrence of rectal cancer)received interstitial high dose rate(Ir-192)brachytherpay with afterloading technique(6.0 Gy/day in 4 days) Tubes were inserted with laparoscopic guidance to minimize the risk of tube misplacement. Results The size of the tumors was reduced and the local control rate was encouraging(6/6). one patient with local recurrence of rectal cancer aquired CR,the ofher five cases acquired PR. Conclusions Interstitial tube insertion with laparoscopic guidance to treat advanced carcinoma in afterloading technique is a simple,minimally invasive,safe and economical method,especially fit for elder patients who intolerate or disagree to operation.

Objective:To investigate the diagnostic performance of T-SPOT test for pediatric tuberculosis (TB).Methods:The results of T-SPOT and PPD in 67 TB children and 71 TB-excluded children that diagnosed and treated in the People's Hospital of Jianyang from June 2014 to May 2017 were retrospectively analyzed.The diagnostic efficacy and consistency of the two tests, and the diagnostic efficacy of combined examination were evaluated.Results:The sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, negative likelihood ratio, Youden′s index of T-SPOT were 88.1%, 94.4%, 93.7%, 89.3%, 15.6, 0.13, 0.83, respectively.While the above parameters of PPD were 68.7%, 74.6%, 71.9%, 71.6%, 2.71, 0.42, 0.43, respectively.T-SPOT had higher sensitivity, specificity, positive predictive value, negative predictive value compared with PPD, and the differences were statistically significant(χ 2=7.44, 10.54, 10.51, 7.45, all P<0.01). The positive rates of T-SPOT for pulmonary and extra-pulmonary TB were 90.9% and 82.6%, and the difference was not statistically significant ( P>0.05). The positive rate of T-SPOT was higher in 5-18 years old group than that in 0-4 years old group(95.1% vs.76.2 %, χ 2=5.01, P<0.05). The latter group held a diagnostic concordance greater than the former(kappa value 0.78 vs.0.23). The sensitivity of combined tests had no statistically significant difference compared with T-SPOT alone( P>0.05). Conclusion:T-SPOT outperformed PPD in diagnostic assistance of pediatric TB overall.The diagnostic superiority is noticeable in the>4-18 years old other than the 0-4 years old.Compared with T-SPOT alone, combined tests should not be regarded to have increased sensitivity.

Objective To explore the correlation between lumbar spine bone mineral density and the occurrence of large rotator cuff tears.Methods A total of 109 patients with arthroscopic shoulder surgery in the Department of Arthroplasty Surgery in Kunshan Hospital of Traditional Chinese Medicine from January 2018 to October 2023 were selected and divided into large rotator cuff tear group(n=27)and small rotator cuff tear group(n=82)according to the severity of the rotator cuff tears.Gen-eral materials of patients were collected,and multivariate Logistic regression analysis was used to in-vestigate the correlation between lumbar spine bone mineral density and the occurrence of large rotator cuff tears.Results The large rotator cuff tear group had significant higher age and higher proportion of patients with a history of trauma compared to the small rotator cuff tear group(P＜0.05);addition-ally,the levels of total cholesterol,albumin,serum magnesium,total hip bone mineral density,and lumbar spine bone mineral density were significantly lower in the large rotator cuff tear group(P＜0.05).The results of multivariate Logistic regression analysis indicated that lumbar spine bone mineral density was associated with the occurrence of large rotator cuff tears.The prevalence of large rotator cuff tears across the four quartile intervals of lumbar spine bone mineral density named as Q1(＜0.870 g/cm2),Q2(0.870～＜0.991 g/cm2),Q3(0.991～1.137 g/cm2),and Q4(＞1.137 g/cm2)were 48.15％,29.63％,18.52％and 3.70％respectively,showing a gradual decreasing trend with significant differences(P＜0.05).Conclusion There is a correlation between lumbar spine bone mineral density and large rotator cuff tears.The lower the bone density of the lumbar spine is,the higher the risk of large rotator cuff tears will be.

Objective To understand the etiological characteristics and risk factors of respiratory virus infection in children with bronchial asthma, and to provide theoretical basis for the prevention and treatment of respiratory virus infection in children with bronchial asthma. Methods A total of 374 children with bronchial asthma who were treated in Jianyang People's Hospital from December 2018 to December 2020 were enrolled. Pharyngeal swabs were collected from the outpatient children on the day of treatment, and 2 mL of nasopharyngeal secretions were collected from the hospitalized children within 24 hours by negative pressure aspirator. Seven viral antigens including RSV, ADV, IVA, IVB, PIVI, PIV II, and PIV III were detected. According to whether the virus test results were positive or not, they were divided into the experimental group (n=191) and the control group (n=183). Logistic regression analysis was used to screen the risk factors of respiratory virus infection in children with bronchial asthma. Results Among the 374 samples, the virus positive rate was 51.07% (191/374), and the top 3 virus species in the positive samples were RSV, ADV, and PIV III, accounting for 41.36% (79/191), 30.36% (58/191), and 9.42% (18/191), respectively. In addition, IVA accounted for 5.24% (10/191), PIV II accounted for 5.24% (10/191), PIVI accounted for 3.66% (7/191), and IVB accounted for 1.57% (3 /191). The positive rates of virus were 47.96% (94/196) and 54.49% (97/178) in male and female children, respectively, with no significant difference (χ²=1.597，P>0.05). The positive rate of 1~3 years old children was significantly higher than that of >3 years old group (χ²=6.412，P<0.05). There were significant differences in the frequency of asthma attack, intravenous glucocorticoid application and the onset season between the two groups (P<0.05). Further analysis showed that the frequency of asthma attack >3 times, intravenous glucocorticoid application and onset season were independent risk factors for respiratory virus infection in children with bronchial asthma (P<0.05). Conclusion The infection season of acute respiratory tract infection in children with asthma is mainly concentrated in autumn and winter, with RSV as the main viral pathogen. Targeted preventive measures should be given to children with bronchial asthma who have more than 3 asthma attacks and intravenous glucocorticoid application, which can reduce respiratory virus infection in children with asthma.
