Viral pneumonia is an infectious disease caused by virus invading the lung parenchyma and interstitial tissue and causing lung inflammation， with the incidence rising year by year. Traditional Chinese medicine （TCM） can treat viral pneumonia in a multi-component， multi-target， and holistic manner by targeting the core pathogenesis of pneumonia caused by different respiratory viruses， demonstrating minimal side effects and significant advantages. According to the theory of healthy Qi and pathogenic Qi in TCM， the struggle between healthy Qi and pathogenic Qi and the imbalance between immunity and inflammation run through the entire process of viral pneumonia， and the immunity-inflammation status at different stages of the disease reflects different relationships between healthy Qi and pathogenic Qi. Immune dysfunction leads to the deficiency of healthy Qi， causing viral infections. The struggle between healthy Qi and pathogenic Qi causes immunity-inflammation imbalance， leading to the onset of viral pneumonia. Inflammatory damage causes persistent accumulation of phlegm and stasis， leading to the progression of viral pneumonia. The cytokine storm causes immunodepletion， leading to the excess of pathogenic Qi and diminution of healthy Qi and the deterioration of viral pneumonia. After the recovery from viral pneumonia， there is a long-term imbalance between immunity and micro-inflammation， which results in healthy Qi deficiency and pathogenic Qi lingering. Healthy Qi deficiency and pathogenic Qi excess act as common core causes of pneumonia caused by different respiratory viruses. Clinical treatment should emphasize both replenishing healthy Qi and eliminating pathogenic Qi， helping to restore the balance between healthy Qi and pathogenic Qi as well as between immunity and inflammation， thus promoting the recovery of patients from viral pneumonia. According to the TCM theory of healthy Qi and pathogenic Qi， this article summarizes the immunity-inflammation mechanisms at different stages of viral pneumonia， and explores the application of the method of replenishing healthy Qi and eliminating pathogenic Qi in viral pneumonia. The aim is to probe into the scientific connotation of the TCM theory of healthy Qi and pathogenic Qi in viral pneumonia and provide ideas for the clinical application of the method of replenishing healthy Qi and eliminating pathogenic Qi to assist in the treatment of viral pneumonia.

The principle of treating different diseases with the same therapy is the essence of syndrome differentiation and treatment in traditional Chinese medicine （TCM）. It means that when the same pathogenic changes or the same symptoms appear in the development of different diseases， the same principles or methods can be used for treatment. Due to the complexity and high variability of viral pathogenicity， the precise and effective treatment of different types of viral pneumonia （VP） has always been a research focus and difficulty in modern medicine. VP belongs to the category of external-contraction febrile disease， warm disease， and epidemic in TCM. Haoqin Qingdantang （HQQDD） is a representative formula for clearing heat and dispelling dampness in warm diseases， and its intervention in VP caused by various viral infections has significant effects. This study， guided by the theory of treating different diseases with the same therapy， links the related studies on using HQQDD to treat different types of VP and finds that influenza virus pneumonia （IVP）， severe acute respiratory syndrome （SARS）， and COVID-19 all have a common pathogenic mechanism of dampness-heat at different stages of respective diseases. When these diseases are dominated by damp-heat factors， the use of HQQDD yields remarkable therapeutic effects. Modern pharmacological studies have confirmed that HQQDD can inhibit virus replication， reduce fever reactions， inhibit the expression of inflammatory mediators， and regulate immune balance. Moreover， the sovereign medicine in this formula has excellent antiviral activity， and the formula reflects rich scientific connotations of treating VP. According to the theory of treating different diseases with the same therapy and based on the effective treatment practice and modern pharmacological research of HQQDD for different types of VP， this paper mines the underlying TCM theory of treatment with the same therapy， explores the syndrome differentiation and treatment strategy and effect mechanism of this formula for different types of VP， and analyzes the treatment mechanism and characteristics， with the aim of providing evidence and reference for the clinical application and modern research of HQQDD.

The patient is a 60 year old male who has been experiencing thrombocytosis for over 2 years. He was treated outside the hospital in August 2023 due to acute myocardial infarction. After he left the hospital, there was still dizziness and persistent elevation of hemoglobin and platelets during follow-up. In November 2023, the patient went to Zhongshan Hospital affiliated with Fudan University for treatment. After admission, elevated platelets and hemoglobin were found, and genetic testing showed positive mutations in JAK2-V617F and CALR gene L367fs * 46, diagnosed as chronic myeloproliferative neoplasms (polycythemia vera and primary thrombocythemia). Discharge order was 0.1 g of hydroxyurea once a day. Follow up after six months showed improvement in hemoglobin and platelets compared with that at admission. This case suggests that classic driver gene mutation testing of myeloproliferative neoplasm is an important indicator for disease diagnosis for patients with thrombocytosis and hemoglobin increase.

Objective:To explore the differences in clinical phenotype characteristics and auxiliary test results of Gerstmann-Str?ussler-Scheinker syndrome (GSS) patients in the same family with GSS carrying a P102L mutation in the PRNP gene. Methods:A family with GSS carrying a P102L mutation in the PRNP gene, which was identified and treated at the Department of Neurology, Xuanwu Hospital, Capital Medical University in January 2024 was collected. A comprehensive evaluation was conducted on the proband, including neuropsychological examination, imaging studies, electroencephalogram, cerebrospinal fluid (CSF) analysis, real-time quaking-induced conversion (RT-QuIC) assay of skin biopsy samples, and genetic testing. At the same time, a survey and analysis were conducted on the family members. Skin RT-QuIC, genetic testing and neuropsychological evaluation were performed on some of the family members. Results:Among the 4-generation members of the GSS family, there were 5 GSS patients, including the proband′s father, younger brother, uncle and cousin. The proband, her younger brother and cousin all carried the P102L mutation in the PRNP gene, and her son was a carrier of the P102L mutation in the PRNP gene. The proband was a 53 years old female, and had a typical GSS phenotype, with the initial symptom of ataxia. The CSF 14-3-3 protein was negative and there were no abnormalities observed on her brain magnetic resonance imaging. The skin and CSF RT-QuIC test results of the proband were both negative. The cousin of the proband had a typical GSS phenotype, and his skin RT-QuIC test result was negative. The younger brother of the proband had a GSS phenotype of Creutzfeldt-Jakob disease type, with the initial symptom of rapidly progressing dementia and a positive skin RT-QuIC test result. The first symptoms of the proband′s father and uncle were both ataxia, and they had passed away without undergoing genetic testing. The son of the proband was a carrier of the P102L mutation in the PRNP gene and had no clinical symptoms. Conclusion:Different family members in the same GSS family may exhibit different clinical phenotypes, and GSS with different phenotypes have differences in RT-QuIC results.

Objective:To investigate the effect and safety of the double-cross dressing technique for composite rhytidectomy.Methods:A retrospective analysis was performed on a total of 121 patients with face and neck ageing, who were admitted to the Facial and Neck Plastic Surgery Center, the Plastic Surgery Hospital of the Chinese Academy of Medical Sciences from June 2020 to May 2023, all female with the age ranged 34-72 years old. All the patients underwent a full facial and neck composite rhytidectomy. Immediately after surgery, a double-cross bandaging was applied. The cotton pad was nested on the outer auricle, so that the front of the ear and the back of the ear were the first cross. This cross aimed to accurately pressurized the temporal, buccal region and postauricle flap. The second cross occurred at the radix. It secured composite tissue flap at the zygomatic arch and the buccal fat pad zone. Patient′s external auricle was not compressed after bandaging. The healing and the occurrence of complications were observed.Results:All the patients were satisfied with the comfort of the bandaging, the satisfied rate was 100% (121/121). All the patients had different degrees of periocular and perioral swelling 72 hours after surgery. Conjunctival edema and xanthochromia occurred in 30 patients, and oral mucosal congestion occurred in 25 patients, all of which were spontaneously resolved 2-4 weeks after surgery. Postoperative nursing was easily managed. There were no events such as dressing loosening, blocked draining tubes, and difficulty in replacing tubes. All the patients were followed up for 3-12 months after surgery, the flap in the postauricular area of all patients healed well, and there were no adverse complications such as wound infection, necrosis of the flap in the operative area, and delayed healing of the incision.Conclusion:The double-cross bandaging technique achieves the comfort bandaging and good protection of the face, which is safe and effective.

Objective:To evaluate the effect of disulfiram on sepsis-associated encephalopathy (SAE) and the relationship with NOD-like receptor family pyrin domain-containing 3 (NLRP3)/caspase-1 signaling pathway in rats.Methods:Forty-five SPF healthy male Sprague-Dawley rats, aged 8-12 weeks, weighing 200-220 g, were divided into 3 groups ( n=15 each) using a random number table method: sham operation group, SAE group, and SAE+ disulfiram group (SAE+ DSF group). The SAE model was established by by using cecal ligation and puncture in anesthetized rats. SAE+ DSF group received an intraperitoneal injection of 50 mg/kg disulfiram 4 h before the cecal ligation and puncture. The survival status of rats was recorded within 72 h after surgery. Their neurobehavioral scores were assessed and recorded on days 1-3 after surgery. On the 3rd day after surgery, novel object recognition test (cognitive index) and open field test (activity distance and time in the central area) were conducted sequentially. Following the behavioral testing, the rats were anesthetized, and their hippocampi were dissected and isolated to observe the pathological changes in the hippocampal region (using HE staining) and to determine the expression of NLRP3 and caspase-1 (by Western blot) and the expression of interleukin-1beta (IL-1β), IL-18 and tumor necrosis factor-alpha (TNF-α) mRNA (by fluorescent quantitative polymerase chain reaction). Results:Compared with Sham group, the 72-h survival rate and postoperative neurobehavioral scores were significantly decreased, the activity distance and time in the central area of the open field were shortened, and the cognitive index was decreased, the expression of NLRP3, caspase-1 and IL-1β, IL-18 and TNF-α mRNA was up-regulated ( P<0.05), and the pathological damage was marked in the hippocampus in SAE group ( P<0.05). Compared with SAE group, postoperative neurobehavioral scores were significantly increased, the activity distance and time in the central area of the open field were prolonged, the cognitive index was increased, and the expression of NLRP3 and caspase-1 and IL-1β, IL-18 and TNF-α mRNA was down-regulated ( P<0.05), no significant change was found in the 72-h survival rate ( P>0.05), and the pathological damage to the hippocampus was significantly alleviated in SAE+ DSF group. Conclusions:Disulfiram can alleviate SAE in rats, and the mechanism may be related to the inhibition of the NLRP3/caspase-1 signaling pathway.

Renal metastasis of oral adenoid cystic carcinoma is rare. A patient with bilateral renal metastasis secondary to surgery for oral adenoid cystic carcinoma was reported. The left kidney was treated with radiofrequency ablation, and the right kidney was treated with radical nephrectomy. The creatinine was 74 μmol/L at 3 months after surgery. The multidisciplinary comprehensive diagnosis and treatment model adopted in this case provided diagnosis and treatment ideas for patients with bilateral renal secondary malignant tumors.

In order to realize the quantitative assessment of muscle strength in hand function rehabilitation and then formulate scientific and effective rehabilitation training strategies, this paper constructs a multi-scale convolutional neural network (MSCNN) - convolutional block attention module (CBAM) - bidirectional long short-term memory network (BiLSTM) muscle strength prediction model to fully explore the spatial and temporal features of the data and simultaneously suppress useless features, and finally achieve the improvement of the accuracy of the muscle strength prediction model. To verify the effectiveness of the model proposed in this paper, the model in this paper is compared with traditional models such as support vector machine (SVM), random forest (RF), convolutional neural network (CNN), CNN - squeeze excitation network (SENet), MSCNN-CBAM and MSCNN-BiLSTM, and the effect of muscle strength prediction by each model is investigated when the hand force application changes from 40% of the maximum voluntary contraction force (MVC) to 60% of the MVC. The research results show that as the hand force application increases, the effect of the muscle strength prediction model becomes worse. Then the ablation experiment is used to analyze the influence degree of each module on the muscle strength prediction result, and it is found that the CBAM module plays a key role in the model. Therefore, by using the model in this article, the accuracy of muscle strength prediction can be effectively improved, and the characteristics and laws of hand muscle activities can be deeply understood, providing assistance for further exploring the mechanism of hand functions .
