This paper summarized professor WU Mianhua's experience in the treatment of tumors using Hehuanhua （Flos Albiziae）. He believes that the occurrence and development of tumors are closely related to emotions， and thereafter proposed the concept of "masses usually due to constraint， and should be treated by regulating the spirit".Hehuanhua is a light and aromatic flower that enters the heart， liver and spleen meridians， and is good at relieving constraint and regulating the spirit， harmonizing the center with aroma， which can be used to treat all kinds of tumor-related complications. Hehuanmi is flower buds， picked before the flowers fully blooms， have the effect of clearing and lightening upward， opening up the heart and mind， and unblocking liver qi. Commonly used formulas include self-made Ningxin Anmian Decoction （宁心安眠汤） to treat tumor-related insomnia， self-made Aitongxiao Formula （癌痛消方） to treat tumor-related pain， self-made Erhua Jieyu Formula （二花解郁方） to treat tumor-associated depression， and self-made Shugan Tiaohe Decoction （疏肝调和汤） to deal with peri-menopausal state after the treatment of tumors. Hehuanhua is an inflorescence， which captures the aromatic essence and has the function of removing the filth and turbidity， and can wake up the spleen and harmonize the stomach； therefore， it is often used in self-made Tiaomu Hezhong Decoction （调木和中汤） to treat chemotherapy-related digestive tract adverse reactions or combined with rose flowers to treat chemotherapy-induced oral ulcers.

BACKGROUND: The proportion of patients with non-small cell lung cancer (NSCLC) harboring epidermal growth factor receptor (EGFR) mutations is relatively high in China. However, these patients currently lack significant benefits from available neoadjuvant treatment options. This study aims to explore the potential application value of neoadjuvant targeted therapy by evaluating its efficacy and safety in patients with EGFR-mutant resectable lung adenocarcinoma. METHODS: A multicenter retrospective study was used to analyze the treatment effect of patients with stage IIA-IIIB EGFR-mutant lung adenocarcinoma who underwent surgical resection after receiving neoadjuvant targeted therapy from July 2019 to October 2024. RESULTS: A total of 24 patients with EGFR-mutant lung adenocarcinoma from three centers were included in this study. All patients successfully underwent surgery and achieved R0 resection of 100.0%. The objective response rate (ORR) was 83.3% (20/24) . The major pathologic response (MPR) rate was 37.5% (9/24), with 2 patients (8.3%) achieving pathological complete response (pCR). During neoadjuvant therapy, 13 out of 24 patients (54.2%) experienced adverse events of grade 1-2, with no occurrences of ≥ grade 3. The most common treatment-related adverse events were rash (n=4, 16.7%), mouth sores (n=2, 8.3%), and diarrhea (n=2, 8.3%). The median follow-up time was 33.0 months, no deaths occurred in all patients, and the overall survival (OS) rate was 100.0%. The 1-year disease-free survival (DFS) rate was 91.1%, and the 2-year DFS rate remained at 86.2%. CONCLUSIONS The application of neoadjuvant targeted therapy in patients with EGFR-mutant resectable lung adenocarcinoma is safe and feasible, and is expected to become a highly promising neoadjuvant treatment option for the patients with EGFR-mutant lung adenocarcinoma.

OBJECTIVE To investigate the effects of Buyang huanwu decoction on red blood cells in hyperlipidemia model mice. METHODS Male C57BL/6 mice were fed a high-fat diet to prepare a hyperlipidemia model. Successfully modeled mice were randomly assigned to the model group， atorvastatin calcium group （0.26 g/kg）， fenofibrate group （1.3 mg/kg）， and high-， medium-， and low- dose groups of Buyang huanwu decoction （18.6， 9.3， 4.6 g/kg）， with 10 mice in each group. Additionally， 10 mice fed with regular chow served as the normal group. Each group of mice received intragastric administration with the corresponding drug or normal saline once daily for 21 consecutive days. After the last administration， the body weight of the mice in each group was measured， and blood glucose， total cholesterol （TC）， triglyceride （TAG）， high-density lipoprotein cholesterol （HDL-C）， and low-density lipoprotein cholesterol （LDL-C） levels were measured. Red blood cell morphology changes were observed， and the expression levels of glucose transporter type 1 （GLUT1）， erythrocyte membrane protein band 4.2 （protein 4.2）， caveolin-1， and flotillin-1 in erythrocyte membrane were determined. RESULTS Compared with the model group， the body weight and levels of TC， TAG， HDL-C， LDL-C， and the expression levels of GLUT1， caveolin-1 and flotillin-1 in the Buyang huanwu decoction groups were significantly decreased， while blood glucose levels and the expression levels of protein 4.2 were significantly increased （P＜0.05）. The red blood cell morphology in the low- and medium-dose groups of Buyang huanwu decoction was significantly promoted. CONCLUSIONS Buyang huanwu decoction can reduce blood lipid levels in hyperlipidemia model mice and strengthen the morphology and function of red blood cells in a hyperlipidemic environment， which has the potential to be used for preventing hyperlipidemia complications such as atherosclerosis.

Objective:To investigate the alteration of glymphatic system based on diffusion tensor image-analysis along the perivascular space(DTI-ALPS)in bipolar disorder Ⅰ(BD-Ⅰ).Methods:A total of 44 BD-Ⅰ patients(BD-Ⅰ group) admitted to the Affiliated Brain Hospital of Guangzhou Medical University from January 2012 to December 2017 were selected.In addition, totally 30 healthy controls (HC group) were recruited. The diffusion tensor image data were analyzed retrospectively, and along the perivascular space (ALPS) index was calculated. Hamilton anxiety scale (HAMA), 17-item Hamilton depression rating scale (HAMD-17), Young mania rating scale (YMRS) and global assessment function (GAF) were used to evaluate the severity of anxiety, depression, mania and social function respectively. SPSS 25.0 software was used for t-test, Z-test and chi-square test, and the differences in clinical data and DTI-ALPS index between the two groups were compared. The partial correlation test was used to analyze the correlations between DTI-ALPS index and the clinical indicators such as HAMA, HAMD-17, YMRS and GAF. Results:The DTI-ALPS indexes in left(1.69±0.17), right(1.44±0.15) and bilateral cerebral hemispheres(1.56±0.15) of BD-Ⅰ group were lower than those in HC group ((1.71±0.15), (1.46±0.13) and (1.58±0.12)), but the differences were not statistically significant ( t=-0.441, -0.545, -0.556, all P>0.05). After controlling for gender, age, years of education and course of disease, there were significant negative correlations between bilateral average DTI-ALPS index and somatic anxiety ( r=-0.334, P=0.038), as well as between right DTI-ALPS index and somatic anxiety( r=-0.349, P=0.030) in BD-Ⅰ group. Conclusion:The dysfunction of cerebral glymphatic system is not obvious in BD-Ⅰ patients, but their anxiety may be related to dysfunction cerebral glymphatic system.

Poria cocos is a classic Chinese medicine with homology of food and medicine,which is beneficial to water infiltration,spleen and stomach,calming the heart and calming the mind,etc.It is known as"nine Poria cocos in ten prescriptions".Poria cocos contains polysaccharide,triterpenoids and steroids,among them polysaccharide and triterpenoid are considered as the main active components.Modern studies have shown that Poria cocos polysaccharide triterpenes display pharmacological activities such as anti-tumor,immunomodulatory and anti-oxidation.The dissolution rate of poria cocos and triterpenes was low in the traditional decocting process,and the oral absorption rate of poria cocos was low,but the activity of poria cocos and triterpenes was still very good,indicating the high activity of poria cocos and triterpenes.Therefore,this paper systematically reviews the extraction and separation,structural identification,content determination,structural modification,biosynthesis,pharmacological activity and potential product development value of Poria cocos polysaccharide and triterpenoids,in order to provide literature reference for the development of Poria cocos grand health industry.

OBJECTIVES: Platelet-to-lymphocyte ratio (PLR) has recently been investigated as a new inflammatory marker in many inflammatory diseases, including systemic lupus erythematosus and immunoglobulin A vasculitis. However, there were very few reports regarding the clinical role of PLR in patients with anti-neutrophil cytoplasmic antibody (ANCA) associated vasculitis. This study was thus undertaken to investigate the relationship between inflammatory response and disease activity in Chinese patients with myeloperoxidase-anti-neutrophil cytoplasmic antibody (MPO-ANCA) associated vasculitis. Furthermore, we evaluated whether PLR predicts the progression of end stage of renal disease (ESRD) and all-cause mortality. METHODS: The clinical, laboratory and pathological data, and the outcomes of MPO-ANCA associated vasculitis patients were collected. The Spearman correlation coefficient was computed to examine the association between 2 continuous variables. Cox regression analysis was used to estimate the association between PLR and ESRD or all-cause mortality. RESULTS: A total of 190 consecutive patients with MPO-ANCA associated vasculitis were included in this study. Baseline PLR was positively correlated with CRP (r=0.333, P<0.001) and ESR (r=0.218, P=0.003). PLR had no obvious correlation with Birmingham Vasculitis Activity Score (BVAS). Patients having PLR≥330 exhibited better cumulative renal survival rates than those having PLR<330 (P=0.017). However, there was no significant difference in the cumulative patient survival rates between patients with PLR≥330 and those with PLR<330 at diagnosis (P>0.05). In multivariate analysis, PLR is associated with the decreased risk of ESRD (P=0.038, HR=0.518, 95% CI 0.278 to 0.963). We did not find an association between PLR with all-cause mortality using multivariate analysis (HR=1.081, 95% CI 0.591 to 1.976, P=0.801). CONCLUSIONS PLR is positively correlated with CRP and ESR. Furthermore, PLR may independently predict the risk of ESRD.

Objective:To discuss the clinical curative effect of the minimally invasive percutaneous suture technique of eight times for repairing closed injury extensor tendon zone I of finger.Methods:From February 2017 to January 2020, 12 patients (male 8, female 4) with mallet finger deformity were retrospectively studied, with an average age of 35 years (range, 18-50 years). And all the affected fingers were acute closed rupture of extensor tendon in zone I of single finger, 5 cases of the left finger and 7 cases of the right finger. There were 1 case of the thumb finger, 2 cases of the index finger, 3 cases of the middle finger, 4 cases of the ring finger and 2 cases of the little finger. 12 patients with fresh sputum mallet fingers were with 3-0 thread monofilament suture on extensor tendon zone I of finger in the minimally invasive percutaneous suture technique of eight times, and the distal end of the tendon was fixed to the base of the distal phalanx through the bone hole. Removal of the Kirschner wire 6-8 weeks, the brace was used to fix the affected finger in the dorsal extension. The flexion and extension of the affected finger was gradually strengthened. The function of the affected finger was evaluated according to the Crawford standard after operation and follow-up. The active flexion and extension range of motion of each joint of the affected finger and the contralateral healthy finger were measured, and the total action movement (TAM) of the finger were recorded. Finger function was evaluated according to TAM of the American Association of Hand Surgeons.Results:All operations were successfully completed, the operation time of the patients ranged from 18 to 25 min, with an average of 20.1±0.2 min. There was only a small amount of bleeding in the surgery. All 12 cases were followed up and the follow-up periods ranged from 6 to 14 months, with an average of 10.2±1.1 months. Mallet finger deformities were all corrected postoperatively; there were no knot exposure, skin necrosis and other complications. According to the Crawford standard, 9 cases were excellent, 2 cases were good, and 1 case was fair. The excellent and good rate was 91.7% (11/12). The mean active flexion of distal interphalangeal joints on the wounded finger and healthy finger were 82.11°±2.02° and 84.09°±2.01°, the mean active extension of distal interphalangeal joints on the wounded finger and healthy finger were -2.04°±3.01° and 0.02°±1.02°, there were significant differences between them ( t=2.447, 3.246; P=0.019, 0.004). The degrees of active joint activity of wounded finger were: 91.02°±4.01° of the metacar-pophalangeal joint, 94.04°±2.11° of the proximal interphalangeal joint, 83.01°±2.02° of the distal interphalangeal joint, and 265.05°±13.04° of total active activity; the degrees of active joint activity of healthy finger were: 93.01°±3.21° of the metacar-pophalangeal joint, 94.03°±3.07° of the proximal interphalangeal joint, 85.02°±2.01° of the distal interphalangeal joint, and 269.02°±12.10° of total active activity. The TAMs of the healthy side were 269.02°±12.10°, and the TAMs of the affected side were 265.05°±13.04°, there was no significant difference between them ( P>0.05). According to TAM system assessment criteria: excellent in 9 patients, good in 3 patients, and the excellent and good rate was 100% (12/12). Conclusion:The minimally invasive percutaneous suture technique of eight times can well repair closed injury extensor tendon zone I of finger, can have satisfactory treatment outcome in mallet finger with a simple procedure and good outcome. It is a simple, safe, effective method with minimal invasion.

Objective: To investigate the efficacy and safety of cuboid stereotactic aspiration of necrotic brain tissue for treating malignant middle cerebral artery infarction in the elderly patients. Methods: Sixteen elderly patients with malignant middle cerebral artery infarction were selected from June 2017 to January 2019 in our hospital. Patients were followed up for 6 months to evaluate the efficacy of stereotactic aspiration of necrotic brain tissue using the modified Rankin Scale (mRS). Results: The 30-day mortality was 18.75%. Among the 16 elderly patients, 6 (37.5%) had an mRS score of 3 (defined as moderate disability), 6 (37.5%) had an mRS score of 4 (defined as moderate to severe disability), 1 (6.25%) had an mRS score of 5 (defined as severe disability), and 3 (18.75%) had an mRS score of 6. The probability of 6-month favorable outcome, defined as an mRS score of ≤3, was 37.5%, and the 6-month mortality was 18.75%. Conclusions It is a simple, minimally invasive, effective and safe method to treat malignant middle cerebral artery infarction in the elderly patients with cuboid stereotactic aspiration of necrotic brain tissue, which needs to be confirmed by further randomized controlled studies.

Objective To evaluate the therapeutic effect of antibiotics combined with recombinant tuberculosis vaccine AEC/BC02 on Mycobacterium tuberculosis infection in guinea pigs. Methods Two weeks after guinea pigs were challenged subcutaneously with a high dose of Mycobacterium tuberculosis,the guinea pigs with the positive skin test responses to the recombinant ESAT6-CFP10 allergen were randomly di-vided into four groups:normal saline (NS),AEC/BC02,antibiotics and antibiotics+AEC/BC02. In antibiotics+AEC/BC02 group,guinea pigs firstly received isoniazid ( INH) and rifapentine ( RFT) treatment once a week for a total of three times,and then were immunized with a single dose of AEC/BC02 vaccine six times at 10-day intervals. Guinea pigs in AEC/BC02 and antibiotics groups were respectively vaccinated with AEC/BC02 vaccine and given INH and RFT treatment at the same dose and frequency as given to antibiotics+ AEC/BC02 group. Thirteen weeks after challenge,all guinea pigs were sacrificed for necropsy. Results The gross pathological scores of NS,AEC/BC02,antibiotics and antibiotics+AEC/BC02 groups were 83±8,77± 22,45±28 and 19±14,respectively. Antibiotics+AEC/BC02 group had a significantly lower gross pathological score than antibiotics,AEC/BC02 and NS groups (P<0. 05,P<0. 01,P<0. 01,respectively). Moreover,the gross pathological scores of antibiotics and AEC/BC02 groups were significantly decreased as compared with that of NS group (both P<0. 01). However,there was no significant difference between AEC/BC02 and NS groups. The spleen bacterial load of antibiotics+AEC/BC02 group was (2. 50±1. 26) lg CFU,which was sig-nificantly lower than those of NS [(4. 92+0. 52) lg CFU],AEC/BC02 [(4. 78+0. 84) lg CFU] and antibi-otics [(4. 39+0. 50) lg CFU] groups (P<0. 01). Compared with NS group,antibiotic and AEC/BC02 groups showed no significant difference in spleen bacterial load. Histopathological changes indicated different levels of granulomatous lesions appeared in lung tissues of all groups and the most severe change was ob-served in AEC/BC02 group,followed by that in NS,antibiotics and antibiotics+AEC/BC02 groups. Conclu-sion INH and RFT treatment in combination with AEC/BC02 vaccine in the treatment of guinea pigs with Mycobacterium tuberculosis infection was superior to either treatment alone as it significantly alleviated organ lesions and lowered the bacterial loads in spleen and lung.

BACKGROUND: Postoperative cholangitis is a common but severe complication after Kasai portoenterostomy for biliary atresia (BA). This study aimed to identify its prognostic factors. METHODS: Two sets of liver paraffin-embedded tissue samples were collected from BA patients who received Kasai portoenterostomy (n = 25 and n = 31, respectively). Patients were divided into non-cholangitis and cholangitis groups. The infiltration of CD4+, CD8+, CD45RO+, CD68+ cells and expression of Beclin1 were quantitatively evaluated in immunohistochemical analysis. RESULTS: Cholangitis group had a significantly lower CD8+ T cell infiltration but a higher CD45RO+ cell infiltration, and a lower Beclin1 level than non-cholangitis group (all P < 0.01). Multivariate logistic regression analysis indicated that infiltration of CD8+ cells (odds ratio [OR], 0.112; 95% confidence interval [CI], 0.022–0.577) and CD45RO+ cells (OR, 3.88; 95% CI, 1.37–11.03), and Beclin1 level (OR, 0.088; 95% CI, 0.018–0.452) were independent influence factors for early postoperative cholangitis. Receiver operating characteristic (ROC) analysis showed that area under ROC curve (AUROC) values for CD8+ cells, CD45RO+ cells and Beclin1 were 0.857, 0.738 and 0.900, respectively. CONCLUSION: Our findings demonstrated the CD8+ cells, CD45RO+ cells and Beclin1 level possessed the prognostic value for early postoperative cholangitis following Kasai operation, which may be helpful to develop new prevention and treatment strategies for postoperative cholangitis.
