Objective To investigate the clinical characteristics,treatment and prognosis of tuberculosis in patients with autoimmune diseases after tumor necrosis factor-αinhibitors.Methods Clinical data of 33 patients with TB after biologics(tumor necrosis factor-α inhibitors)treated in Guangzhou Chest Hospital from January 2019 to March 2023 were collected,including 25 males and 8 females,with a median age of 32 years.The clinical symptoms,laboratory results,imaging and tracheoscopic features,pathological features,treatment and outcome were analyzed retrospectively.Results The common clinical manifestations were cough(26/33),sputum(23/33)and fever(17/33).The most common cases were pulmonary tuberculosis(32/33),bronchial tuberculosis(15/33),mediastinum and hilar lymph node tuberculosis(11/33).Bilateral lung spread of tuberculosis(21/33),intrapulmonary spread of tuberculosis(bronchus,mediastinal hilar lymph nodes,pleura)(19/33),extrapulmonary tuberculosis(18/33),pulmonary tuberculosis with intrapulmonary or extrapulmonary tuberculosis(26/33).Blood CD4+T lymphocyte test was normal(23/33),and blood IGRA test was positive(27/33).Pulmonary imaging miliary nodules(8/33).The histopathology of the lymph nodes showed atypical granulomatous nodules.The duration of anti-tuberculosis treatment is 8-32 months.1 case of death.Conclusion Patients with autoimmune diseases complicated with tuberculosis after the application of tumor necrosis fact-α inhibitor are more likely to have double lung lesions,which are easy to spread to lung tissues and multiple organs of the body,and have decreased immune function.Most of them need to extend the treatment course,and the prognosis is generally good after comprehensive treatment.

Objective To investigate the value of high frequency magnetoencephalography signals in the localization of refractory temporal lobe epilepsy. Methods Retrospective analysis was performed in 10 patients with refractory temporal lobe epilepsy admitted to and accepted surgery in our hospital from January 2015 to December 2015. Surgical approaches of these patients were determined according to the results of long-term video EEG monitoring (VEEG), MR imaging, and conventional and high-frequency magnetoencephalography (MEG). MEG positioning analysis was performed after the surgery; followed up for 12 months was performed to evaluate the surgical efficacies. Results The surgery was effective in all the 10 patients; 5 patients achieved Engel grading Ⅰ, 2 patients achieved Engel grading Ⅱ, and 3 patients achieved Engel grading Ⅲ. The results of high-frequency MEG analysis indicated that 8 lesions were consistent with the surgical sites, enjoying good results; while the positioning error of the 2 patients was large. Conclusions The localization analysis of high-frequency neuromagnetic signals has the potential to determine epileptogenic zones preoperatively for epilepsy surgery. High-frequency oscillation is a new biomarker for the diagnosis of epilepsy.

Objective:To summarize the application of phage therapy in patients with urinary tract complicated pandrug-resistant Klebsiella pneumoniae infection, and analyze its feasibility and effectiveness.Methods:To retrospectively analyze the clinical data of a patient with complicated urinary tract complex pan-resistant Klebsiella pneumoniae treated by phage from August to September, 2019 in Shanghai Public Health Clinical Center. The female patient, 65 years old, was admitted to the hospital on August 6, 2020. The patient repeated with frequent micturition and urgent micturition half a year before admission. These symptoms were not accompanied by back pain, fever, chills, dysuria, gross hematuria. Urinary culture results in outpatient hospital was pan-resistant Klebsiella pneumoniae. After the patient discontinued application of cefoperazone sulbactam, levofloxacin and other drugs, symptoms such as frequent urination could be relieved after treatment, but appeared repeatedly. In August 2019, the center innovatively applied phage therapy to treat this patient with urinary tract pandrug-resistant bacteria infection.Results:For the first time, we applied 117, 135, 178, GD168 phage mixed solution once a day, for 5 days of continuous bladder infusion. At the same time, meropenem and amikacin was intravenous administration to strengthened the anti-infection treatment. Urine culture was negative for two consecutive times after treatment. However, half a month after the end of the bladder infusion, the patient experienced discomfort such as frequent urination. Urine culture: pan-resistant Klebsiella pneumoniae. The second time, we applied a mixture of three phage strains 130, 131, 909, once a day, for 5 days of continuous bladder infusion. And in the afternoon of the third day of treatment, the renal pelvis was retrogradely intubated and perfused with the above three strains of phage mixture. During the second treatment follow-up until March 30, 2020, the patient's urine culture was reviewed once a month. As a result, no pan-resistant Klebsiella pneumoniae was found, and the patient no longer experienced frequent urination and other symptoms of urination. The treatment process was successful and without severe complications and side effects.Conclusions:Phage urinary tract perfusion is an effective method for the treatment of pan-resistant Klebsiella pneumoniae urinary tract infections. The curative effect is accurate and reliable. The patient did not show obvious complications and adverse reactions during treatment. It can be used as an alternative treatment plan for complex pan-resistant Klebsiella pneumoniae infection.

Bladder cancer(BC) ranks the first of genitourinary tumor in China and is one of the most common urological malignancies, in which 25%-30% of patients were diagnosed with muscle-invasive bladder cancer. Radical cystectomy combined with pelvic lymph node dissection is the standard procedure for treatment, which can effectively avoid tumor recurrence or distant metastasis as well as improve the prognosis of patients. However, some patients may not tolerate or refuse to undergo radical bladder surgery due to worry about high complication rate, high morbidity and poor postoperative quality of life. With the increasing understanding of bladder cancer heterogeneity and biological behavior, the treatment of bladder cancer has changed from a surgery-based treatment model to an individualized and comprehensive treatment model by multidisciplinary collaboration. The bladder-preserving treatment can achieve the same oncological prognosis as that of radical bladder surgery with a better quality of life of the patients, which has become a hot topic and focus of research in muscle-invasive bladder cancer treatment. This article reviewed the progress of research related to the comprehensive treatment of muscle-invasive bladder cancer with preservation of the bladder.

Interferon beta (IFN-beta) and TNF-related apoptosis-inducing ligand (TRAIL) are effective anticancer agents. Adeno-associated virus (AAV) is one of the current most promising gene delivery vectors. Previously, we constructed tumor-targeting AAV-hTERT-IFN-beta and AAV-hTERT-TRAIL by inserting IFN-beta or TRAIL gene into AAV controlled by hTERT promoter. The studies showed that either single IFN-beta or TRAIL gene therapy exhibited a certain extent anticancer effect. Here, we report their inhibitory effects on A549 lung cancer cell growth in vitro and in vivo by combined AAV-hTERT-IFN-beta and AAV-hTERT-TRAIL. Expression of secreted IFN-beta in lung cancer A549 cells infected by AAV-hTERT-IFN-beta was detected by enzyme-linked immunosorbent assay (ELISA). The growth-suppressing effect of AAV-hTERT-IFN-beta in combination with AAV-hTERT-TRAIL on several cancer cell lines was assessed by MTT assay. Apoptosis of A549 cancer cells infected by AAV-hTERT-IFN-beta alone, AAV-hTERT-TRAIL alone, and their combination was evaluated by apoptotic cell staining and flow cytometry (FCM), respectively. The antitumor effect of the combination of AAV-hTERT-IFN-beta with AAV-hTERT-TRAIL in vivo was further evaluated through A549 lung cancer xenograft in nude mice. The results showed that the combinational treatment was superior to any alone and presented intensified tumor cytotoxic and apoptotic effect on A549 cancer cells. Most importantly, the combination of AAV-hTERT-IFN-beta with AAV-hTERT-TRAIL exhibited significant antitumor effect and eliminated all tumor masses in nude mice, which lay a foundation for exploring the molecular mechanisms of combined IFN-beta and TRAIL anti-tumor activity.

Blast injury of the chest injury is the most common wound in modern war trauma and terrorist attacks, and is also the most fatal type of whole body explosion injury. Most patients with severe blast injury of the chest die in the early stage before hospitalization or during transportation, so first aid is critically important. At present, there exist widespread problems such as non-standard treatment and large difference in curative effect, while there lacks clinical treatment standards for blast injury of the chest. According to the principles of scientificity, practicality and advancement, the Trauma Society of Chinese Medical Association has formulated the guidance of classification, pre-hospital first aid, in-hospital treatment and major injury management strategies for blast injury of the chest, aiming to provide reference for clinical diagnosis and treatment.
