Oral lichenoid drug reactions(OLDRs)are inflammatory reactions of the oral mucosa caused by the use of specific drugs in sensitive individuals and are classified as oral lichenoid lesions(OLLs).Its clinical and pathological manifestations do not have significant specificity compared to other types of OLL.Various types of drugs have been re-ported to induce OLDR,including antihypertensive drugs,nonsteroidal anti-inflammatory drugs,hypoglycemic drugs,an-tipsychotics,and immunosuppressants,among other drugs.Apart from local or systemic administrate glucocorticoids,the most effective treatment measure is to stop using suspicious drugs.Most patients can achieve significant relief from mu-cosal ulcers and erosion,but white lines may still remain.OLDR has been widely reported in the literature.However,due to a lack of systematic understanding,we do not have a recognized standard for the diagnosis and treatment of this disease.There are still doubts about the causal relationship between related drugs and oral lichen-like lesions.In re-sponse to the abovementioned problems,we searched the literature on drug-related oral lichen planus and lichen-like le-sions at home and abroad over the past 20 years,most of which were case reports and only a few of which were case-con-trol studies.This article describes the current research status of lichenoid lesions from four perspectives:concepts,sus-picious drugs,clinical and pathological manifestations,and treatment prognosis.We hope to provide a theoretical refer-ence for the prevention,diagnosis,and clinical treatment of related lichenoid lesions.A literature review demonstrated that there are still many unclear issues related to the etiology,pathogenesis,clinical diagnosis and treatment,treatment prognosis,and other aspects of this disease,and further clinical and basic research is needed for in-depth exploration.

Objective To evaluate clinical efficacy of lung transplantation for lung chronic graft-versus-host disease (cGVHD) after hematopoietic stem cell transplantation (HSCT). Methods Clinical data of 12 patients undergoing lung transplantation for lung cGVHD were retrospectively analyzed. Preoperative clinical manifestations and involved organs of patients were analyzed. The lung function before and after lung transplantation was compared, and the survival of patients after lung transplantation was analyzed. Results Eleven patients underwent HSCT due to primary hematological malignancies, including 9 cases of leukemia, 1 case of myelodysplastic syndrome, 1 case of lymphoma. And 1 case underwent HSCT for systemic lupus erythematosus. Among 12 cGVHD patients, skin involvement was found in 8 cases, oral cavity involvement in 5 cases, gastrointestinal tract involvement in 4 cases and liver involvement in 3 cases. All 12 patients developed severe respiratory failure caused by cGVHD before lung transplantation, including 9 cases of typeⅡ respiratory failure and 3 cases of type Ⅰ respiratory failure. Two patients underwent right lung transplantation, 2 cases of left lung transplantation and 8 cases of bilateral lung transplantation. The interval from HSCT to lung transplantation was 75 (19-187) months. Upon the date of submission, postoperative follow-up time was 18 (7-74) months. Ten patients survived, 1 died from severe hepatitis at postoperative 22 months, and 1 died from gastrointestinal bleeding at postoperative 6 months. No recurrence of primary diseases was reported in surviving patients. Conclusions Lung transplantation is an efficacious treatment for lung cGVHD after HSCT, which may prolong the survival time and improve the quality of life of the recipients.

Objective·To explore the correlation between the quantitative results of autofluorescence imaging under computer assistance and the grade of epithelial dysplasia in oral leukoplakia.Methods·From April 2016 to January 2024,357 patients with oral leukoplakia who visited the Department of Oral Mucosal Diseases at Shanghai Ninth People's Hospital,Shanghai Jiao Tong University School of Medicine,were included.Autofluorescence images of the lesions were obtained using a handheld autofluorescence device.These images were converted to grayscale images to obtain quantitative metrics.An ordered multinomial Logistic regression model was fitted in Python,and cumulative probability plots were generated.The dataset was divided into training and testing sets,and a decision tree was generated.Different hyperparameters were adjusted to achieve optimal model performance.Accuracy,precision,and F1 scores were calculated.The model performance was visualized using a confusion matrix.Results·As the degree of epithelial dysplasia increased,the relative mean color level showed a declining trend.In the binary classification of epithelial dysplasia,there was no overlap between the cumulative probability curves of different categories.In the four-category classification,only severe epithelial dysplasia overlapped with other category curves,indicating good discriminative ability of the model.In binary pathological grading,when the training and testing set ratio was 4∶1 and the maximum depth was 2,the accuracy,precision,and F1 scores were 0.792,0.801,and 0.795,respectively.In the four-category pathological grading,when the training and testing set ratio was 9∶1 and the maximum depth was 4,the accuracy,precision,and F1 scores were 0.611,0.537,and 0.569,respectively.Conclusion·Computer-assisted quantitative analysis of autofluorescence images can be used by oral mucosal specialists as a reference to predict the degree of epithelial dysplasia in patients with oral leukoplakia and to monitor their risk of cancer.

The relevant clinical data were reviewed for a female patient of Wilson's disease (WD) with habitual abortion. After orthotopic liver transplantation (LT) due to liver dysfunction compensation, she became pregnant and successfully delivered a healthy baby at Month 9 post-LT. This study explored the impact of LT on pregnancy in WD patients and reviewed the related literature. The recipient has been followed up for over 4 years post-LT. Both mother and child are healthy. It suggested that LT surgery can boost the pregnancy success rate of WD patients. Immunosuppressants may be maintained during pregnancy while avoiding the dosing of mTOR inhibitors, mycophenolate mofetil and azathioprine.

Burning mouth syndrome (BMS) is a chronic oral and facial pain disorder characterized by burning pain in the oral mucosa, with multiple pathogenic factors including psychosocial, neuropathological, endocrine, and immune factors. There is still a lack of effective treatment options that have been demonstrated to work. With the development of research on the pathogenesis and treatment of BMS, multidisciplinary comprehensive treatment has gradually been introduced and become a new trend of diagnosis and treatment. Before multidisciplinary treatment, it is necessary to go through a full and comprehensive diagnosis and analysis, select the best comprehensive treatment plan, take the diagnosis and treatment of stomatology as the basis and premise, and apply other multidisciplinary combined treatment, including the treatment of concurrent diseases, psychological interventions, correction of bad habits, etc. A combination of laser therapy and psychological intervention is a more effective treatment method among the current treatment methods, with high comfort and good acceptance by patients. If necessary, mecobalamin tablets, clonazepam α-lipoic acid and other drugs can be used to nourish nerves and provide symptomatic treatment. The comprehensive multidisciplinary treatment of BMS is expected to become a new trend and provide a new strategy for improving the therapeutic effect.

Objective::Because traditional methods are difficult to identify the fermentation mycelium, DNA barcoding technology was used to quickly identify the raw material strain Paecilomyces hepiali of Jinshuibao capsules and related products. Method::A total of 168 samples of 8 species of P. hepiali and its confusable species were identified by internal transcribed spacer (ITS) sequences, and based on the ITS sequences, P. hepiali specific primers were designed to quickly identify the related products. Result::The length of ITS sequences in 44 P. hepiali samples from different sources was 499 bp and there was no mutation site. It was shown that P. hepiali could be distinguished from 7 confusable species based on ITS sequences. The specific primer (ITS-BF/ITS-BR) of P. hepiali designed by ITS sequences could be amplified to obtain a short fragment of 102 bp in length, which could be used to rapidly identify P. hepiali from other confusable species, and to distinguish relevant products in the market. Conclusion::The rapid identification of P. hepiali and its related products can be achieved through the ITS sequences and specific primers, which provides a reference for the production and quality control of Jinshuibao capsules.
