The comparison between traditional Chinese medicine Jinzhen oral liquid (JZOL) and Western medicine in treating children with acute bronchitis (AB) showed encouraging outcomes. This trial evaluated the efficacy and safety of the JZOL for improving cough and expectoration in children with AB. 480 children were randomly assigned to take JZOL or ambroxol hydrochloride and clenbuterol hydrochloride oral solution for 7 days. The primary outcome was time-to-cough resolution. The median time-to-cough resolution in both groups was 5.0 days and the antitussive onset median time was only 1 day. This randomized controlled trial showed that JZOL was not inferior to cough suppressant and phlegm resolving western medicine in treating cough and sputum and could comprehensively treat respiratory and systemic discomfort symptoms. Combined with clinical trials, the mechanism of JZOL against AB was uncovered by network target analysis, it was found that the pathways in TRP channels like IL-1β/IL1R/TRPV1/TRPA1, NGF/TrkA/TRPV1/TRPA1, and PGE2/EP/PKA/TRPV1/TRPA1 might play important roles. Animal experiments further confirmed that inflammation and the immune regulatory effect of JZOL in the treatment of AB were of vital importance and TRP channels were the key mechanism of action.

Objective: The surgical reconstruction strategy for scar contracture deformity in chin and neck was explored, aiming to obtain better aesthetic outcome. Methods: A retrospective observational study was conducted. From December 2017 to April 2021, 34 patients with scar contracture deformity in chin and neck after burns were hospitalized in the Department of Plastic Surgery of the First Affiliated Hospital of Army Medical University (the Third Military Medical University), aged 12-54 years, including 13 males and 21 females, 4 cases with chin affected only, 7 cases with neck affected only, and 23 cases with both chin and neck affected. The scar areas were 48-252 cm². All the patients were treated by operation with expanded flaps, following the "MRIS" principle of matching of the color and thickness of the repair flaps (match), reconstructing of the aesthetic features of subunits (reconstruction), design of incision according to the plastic principle (incision), and prevention of the surgical incision scar (scar). The rectangular or kidney shaped skin and soft tissue expander (hereinafter referred to as the expander) with rated capacity of 80-400 mL was embedded in the first stage, which was routinely expanded to 3-5 times of the rated capacity of the expander. In the second stage, scar resection and expanded flap excision were performed to repair the secondary wound, and the flap donor site was sutured directly. The expansion ratio of the expander (with average value being calculated), the type of flaps used, the reconstruction of local aesthetic morphology, the appearance of postoperative incision, the survival of flap, and the situation of donor and recipient sites observed during follow-up were recorded. Results: Among the 34 patients, the average expansion ratio of the implanted expander was 3.82 times of the rated capacity of the expander. Three cases were repaired by the expanded local pedicled flap only, 19 cases by the expanded shoulder and/or chest perforator pedicled flap only, 10 cases by the expanded local pedicled flap combined with the expanded shoulder and/or chest perforator pedicled flap, and 2 cases by the expanded local pedicled flap combined with the expanded free flap of the second intercostal perforator of internal thoracic artery. After scar resection, the shapes of lower lip and chin-lip groove were reconstructed in 10 cases, chin process reconstruction and chin lengthening were performed in 16 cases, and the cervico-mental angle and mandibular margin contour were reconstructed in 28 cases. The surgical incision was concealed, most of which were located at the natural junction or turning point of the chin and neck subunits. The vertical incision of neck was Z-shaped or fishtail-shaped. All the expanded flaps in 34 patients survived after operation, of which 8 patients had minor necrosis at the edge or tip of the expanded flaps 1-3 days after operation and healed after dressing change. During the follow-up of 3-18 months, little difference in color and thickness between the expanded flap and the skin of chin and neck was observed, and the aesthetic shape of chin and neck was significantly improved, with mild scar hyperplasia of surgical incision. Conclusions: Reconstruction of scar contracture deformity in chin and neck by using expanded flaps based on the "MRIS" principle is beneficial to improve the quality of surgery and achieve better aesthetic outcome.

Objective: To compare the efficacy of induction chemotherapy with or without autologous hematopoietic stem cell transplantation (auto-HSCT) for newly diagnosed young diffuse large B cell lymphoma (DLBCL) patients. Methods: The retrospective study was performed in 90 cases of young patients (≤60 years) with newly diagnosed DLBCL and an age-adjusted International Prognostic Index (aa-IPI) score of 2 or 3. All of them were treated with R-CHOP (32 cases, rituximab combined with CHOP), dose-intensive regimens (DA-EPOCH, Hyper CVAD/MA or ESHAP) combined with or without rituximab (25 cases), and consolidated with up-front auto-HSCT (33 cases), respectively. The efficacy and the potential predictors were evaluated. Results: ①The median age of 90 patients was 43 (18-60) years old. The median follow-up time was 42 (3-110) months. ②The 5-year progression-free survival (PFS) for R-CHOP group, dose-intensive chemotherapy group and auto-HSCT group were (33.5±10.7) %, (55.3±10.1) % and (65.8±13.6) % (P=0.012), the 5-year overall survival (OS) were (49.7±9.0) %, (61.6±10.2) % and (78.6±7.8) % (P=0.035), respectively. There was no significant difference in 5-years PFS and OS between the R-CHOP group and dose-intensive chemotherapy group (P=0.519, P=0.437) compared with that of the dose-intensive chemotherapy group, auto-HSCT group has higher 5-year PFS (P=0.042). ③ When stratified with IPI score, the high-risk group treated with auto-HSCT (26 cases) showed similar 5-years PFS and 5-years OS to those in the low-risk group with chemotherapy alone (12 cases were in R-CHOP group and 8 cases were in dose-intensive chemotherapy group) [5-years PFS were (62.3 ±14.3)%, (58.3 ±18.6)% and (51.4±18.7)%, respectively, P=0.686; 5-years OS were (69.2±13.9)%, (62.5±15.5)% and (58.3±18.6)%, respectively, P=0.592]. ④However, the high-risk group treated with auto-HSCT (26 cases) showed superior 5-years PFS (P=0.002) and 5-years OS (P=0.019) compared to the high-risk group with chemotherapy alone (20 cases were in R-CHOP group and 17 cases were in dose-intensive chemotherapy group) [5-years PFS were (62.3±14.3)%, (41.1±13.5)% and (21.9±11.6)%, respectively; 5-years OS were (69.2±13.9)%, (51.5%±14.0)% and (35.4±13.6)%, respectively]. ⑤In the univariate analysis, as a whole, patients diagnosed with GCB subtype had higher 3-years PFS (P=0.022) and 3-years OS (P=0.037) compared to non-GCB subtype patients; in subgroup analysis, patients diagnosed with GCB subtype had higher 3-years PFS and 3-years OS compared to non-GCB subtype both in R-CHOP group (P=0.030, P=0.041) and dose-intensive chemotherapy group (P=0.044, P=0.047), but not in auto-HSCT group (P=0.199, P=0.093). ⑥In the multivariate analysis, different molecular classification (GCB/non-GCB) was an independent predictor for PFS and OS both in R-CHOP group [HR=0.274 (95% CI 0.094-0.800), P=0.018; HR=0.408 (95% CI 0.164-1.015), P=0.045] and dose-intensive chemotherapy group [HR=0.423 (95% CI 0.043-1.152), P=0.048; HR=5.758 (95% CI 0.882-6.592), P=0.035]. However, there was no significant difference in PFS and OS for auto-HSCT group between GCB/non-GCB patients. Conclusion: Induction chemotherapy followed by up-front auto-HSCT has significant effect on efficacy for young and untreated patients with high risk DLBCL. Combined with induction chemotherapy followed by up-front auto-HSCT could improve the prognosis of non-GCB patients.

OBJECTIVETo investigate the effect of combined application of Xuebijing Injection ( , XBJ) and resolvin D1 (RvD1) on survival rate and the underlying mechanisms in mice with sepsisinduced lung injury.

METHODSThe cecal ligation and puncture (CLP) method was used to develop a mouse sepsis model. Specific pathogen free male C57BL/6 mice were randomly divided into 5 groups (n=20 each): sham, CLP, CLP+XBJ, CLP+RvD1 and CLP+XBJ+RvD1. After surgery, mice in the CLP+XBJ, CLP+RvD1 and CLP+XBJ+RvD1 groups were given XBJ (25 μL/g body weight), RvD1 (10 ng/g body weight), and their combination (the same dose of XBJ and RvD1), respectively. In each group, 12 mice were used to observe 1-week survival rate, while the rest were executed at 12 h. Whole blood was collected for flow cytometric analysis of leukocyte adhesion molecules CD18, lung tissues were harvested for observing pathological changes, and testing the activity of myeloperoxidase (MPO) and the expression of intercellular cell adhesion molecule 1 (ICAM-1).

RESULTSCompared with the CLP group, the histopathological damage of the lung tissues was mitigated, MPO activity was decreased in the CLP+XBJ and CLP+RvD1 groups (P<0.05). In addition, the 1-week survival rate was improved, proportion of CD18-expressing cells in whole blood and ICAM-1 protein expression in lung tissue were decreased in the CLP+XBJ+RvD1 group (P<0.05 or P<0.01).

CONCLUSIONSXBJ together with RvD1 could effectively inhibit leukocyte adhesion, reduce lung injury, and improve the survival rate of mice with sepsis.

Diffuse large B cell lymphoma（DLBCL）is the most common non-Hodgkin's lymphoma in adults，accounting for 30%-40% of non-Hodgkin's lymphoma in adults. The treatments of this lymphoma mainly include chemotherapy，radiotherapy and autologous hematopoietic stem cell transplantation. A large amount of studies show that autologous hematopoietic stem cell transplantation considered as the main treatmant approach can be used for primary high-risk young and relapsed or refractory DLBCL patients. Many scholars have evaluated the effectiveness of autologous hematopoietic stem cell transplantation for primarily high-risk young and relapsed or refractory DLBCL patients，and tried to improve the effectiveness of transplantation that showed some advantagcs for DLBCL patients.

OBJECTIVETo reveal the allelopathy effect of Astragalus membranaceus var. mongholicus seeds and provide information for the intercrop production.

METHODThe A. membranaceus. var. mongholicus seeds were soaked in distilled water for different time (12, 24, 36, 48, 60 h) , and then the seed extracts were used to study their effects on the seed germination, seedling growth and development of two Codonopsis pilosula.

RESULTThe A. membranaceus var. mongholicus seeds contained some allelopathy compounds. Their soaked liquid had significantly influence on the seed germination and seedling growth of C. pilosula. The seed germination rate, germination power, germination index and vigor index of two C. pilosula calrivar were improved and then inhabited with soaking time elongation. The extract soaking for 24 h significantly improved the germination traits but the extract for 60 h appeared different degrees of inhibiting vigor. The seed extracts soaking ranging between 12 and 60 h all significantly improved the above plant growth of C. pilosula but significant inhibited their radicle growth in length. And with the soaking time elongation the facilitation effect weakened and the inhibiting effect enhanced, especially more significant in the C. pilosula caltivar (Baitiaodangshen).

CONCLUSIONThe A. membranaceus var. mongholicus seeds have allelopathic compounds and the endogenous inhibitor can be extracted when soaked for more than 24 h in water with intact seeds, resulting in improvement of seed germination rate. The C. pilosula could be intercropped in A. membranaceus var. mongholicus field, however, when intercroped it should notice that the intercrop proportion should vary with the caltivar.
