BACKGROUND:The prognosis of patients undergoing percutaneous transforaminal endoscopic discectomy is poor,which is related to the lack of functional physical exercise.Conventional rehabilitation methods have limited efficacy,mainly because the rehabilitation methods are relatively single and lack specificity.Therefore,it is necessary to improve the overall functional physical exercise method.OBJECTIVE:To explore the effect of overall functional physical exercise on lumbar biomechanics in patients with lumbar disc herniation who underwent percutaneous transforaminal endoscopic discectomy.METHODS:120 patients who met the percutaneous intervertebral foramen discectomy indication and underwent percutaneous intervertebral foramen discectomy operation in Henan Provincial People's Hospital from April 2021 to September 2022 were selected as study subjects.They were randomly divided into traditional rehabilitation group and overall functional physical exercise group.Patients in the two groups received 8 weeks of traditional rehabilitation and overall functional physical exercise respectively.Before the exercise intervention and after 8 weeks of intervention,the lsoMed2000 isokinetic muscle strength testing system was used to conduct isokinetic muscle strength testing.The Oswestry Disability Index was used to evaluate lumbar spine function.The visual analog scale was used to evaluate the pain level.The anxiety self-rating scale and depression self-report scale were used to assess symptoms of anxiety and depression.After 8 weeks of exercise intervention,the modified Macnab efficacy evaluation standard was used to evaluate the efficacy.RESULTS AND CONCLUSION:(1)Compared with the traditional rehabilitation group,the peak torque and average power of flexion and extensor in the whole functional physical exercise group increased,the peak torque ratio of flexion and extension decreased,Oswestry disability index score,visual analog scale score,self-rating anxiety scale score and self-rating depression scale score decreased,and the excellent and good rate increased 8 weeks after treatment(P＜0.001).(2)It is concluded that compared with the traditional rehabilitation program,overall functional physical exercise after percutaneous intervertebral foramen discectomy in patients with lumbar disc herniation can effectively enhance lumbar biomechanics and function,relieve pain,reduce postoperative bad mood,and improve prognosis,which has high clinical value.

Breast implant associated-anaplastic large cell lymphoma (BIA-ALCL) is very rare. This 39-year-old female patient, more than 10 years after breast augmentation surgery, had suffered left breast swelling and pain for more than 1 year. The original implant (domestic anatomic shape silicone implant, 260 ml) was surgically removed and the capsule of the left breast implant was completely removed. Postoperative pathology confirmed the diagnosis of BIA-ALCL. The patient recovered well after the surgery. This case is the first reported in China mainland, suggest that doctors should attach great importance to the diseases, and diagnose and treat it timely and accurately.

Objective:To observe the clinicopathological features of bronchiolar adenoma (BA) and mixed squamous cell and glandular papilloma (MSGP). The relationship between them was also analyzed.Methods:Clinical data of eight patients with BA and four patients with MSGP diagnosed in China-Japan Friendship Hospital were collected from January 2018 to January 2020. Hematoxylin-eosin staining and immunohistochemical staining (EnVision method) were used to compare their histopathological characteristics. The hotspots regions of cancer-associated driver genes in lung cancer, using real-time quantitative PCR, were detected in all the cases and the literatures were reviewed.Results:The clinical and imaging manifestations of BA and MSGP were analogous. Histologically they had a two-layer structure including bronchial or bronchiolar-type epithelium and a continuous layer of basal cells,similar to bronchial/bronchiole mucosae. P16 protein was highly expressed in 7/8 of BA and 1/4 of MSGP. Mutations of cancer-associated genes were detected in 4/8 of BA, but none in MSGP.Conclusions:BA and MSGP, derived from different parts of the respiratory tract in the lungs, are rare and benign. Their morphological features overlapped with each other, and some cases are accompanied by genetic changes. It is necessary to pay attention to the differential diagnosis between them and lung adenocarcinoma, especially during the intraoperative diagnosis; and be alert to the potentially malignant components in the tumor or combined cancers.

Objective: To study common problems in BRAF gene mutation detection, and conditions for repetition testing using thyroid fine needle aspiration specimens. Methods: A total of 8 644 cases of thyroid fine-needle aspiration specimens at China-Japan Friendship Hospital were collected between February, 2012 and July, 2018. BRAF gene mutation was detected by real-time PCR. Repeat testing was performed in 237 cases when the results were inconsistent with clinical or cytological diagnosis or when uncertain results were obtained. Results: The final positive rates of BRAF mutation was 22.0% (1 897/8 625). Nineteen cases were excluded due to inadequate DNA samples. The average Ct value of internal quality control was 16.061, and the average Ct value of the positive samples was 19.147. Among 237 repeat tests, 51.4% (19/37) continued to have poor DNA quality and 48.6% (18/37) had adequate DNA resulting in 1 positive case and 17 negative cases. In 40 repetition of initial negative cases, results were unchanged. In initial positive cases, 40.4% (40/99) with a difference of Ct value (between BRAF gene and internal quality control) between 8 to 12 turned negative after repetition, 69.8% (37/53) of these cases with a difference of more than 12 turned negative after repetition. The sensitivity and specificity of BRAF mutation were 83.97% and 96.94%, respectively. Conclusions Difference between BRAF gene Ct value and internal quality control Ct value is recommended as a reliability index for the test result. Cases with a difference greater than 8 should be subjected to repeat testing.
