ObjectiveTo investigate the effect of Xuanfei Zhisou prescription on the interleukin-17 （IL-17） signaling pathway in model rats with chronic obstructive pulmonary disease （COPD）. MethodA total of 60 Wistar rats were randomly divided into a blank group （10 rats） and a model group （50 rats）， and COPD model rats were established by tracheal infusion of lipopolysaccharide combined with passive fumigation. After modeling， the rats were divided into the model group， dexamethasone group， and high， medium， and low-dose Xuanfei Zhisou prescription groups （3.6， 1.8， 0.9 g·kg^-1·d^-1） according to the random number table. Rats in the blank group and model group were given normal saline of 10 mL·kg^-1·d^-1 by gavage administration， and the intervention groups of Xuanfei Zhisou prescription were given corresponding drugs. Rats in the dexamethasone group were given dexamethasone of 2.57×10^-4 g·kg^-1·d^-1 for 28 days. The level of pulmonary function indexes in rats was measured by a pulmonary function detector. The contents of interleukin-6 （IL-6）， interleukin-8 （IL-8）， IL-17， interleukin-1β （IL-1β）， and tumor necrosis factor-α （TNF-α） were detected by enzyme-linked immunosorbent assay （ELISA）. The positive expressions of IL-17A， IL-17RA， nuclear factor-κB activator 1 （Act1）， tumor necrosis factor-associated factor 6 （TRAF6）， p-p38 mitogen-activated protein kinase （p-p38 MAPK）， nuclear factor-κB p65 （NF-κB p65）， and phosphorylation were detected by immunohistochemistry （IHC）. The protein expression levels of IL-17A， IL-17RA， Act1， and TRAF6 in the lung tissue were detected by Western blot. The mRNA expressions of IL-17A， IL-17RA， Act1， and TRAF6 in the lung tissue were detected by Real-time polymerase chain reaction （Real-time PCR）. ResultCompared with the blank group， the serum contents of IL-6， IL-8， IL-17， IL-1β， and TNF-α in the model group were significantly increased （P<0.05）， and the flow rate and volume indexes of pulmonary function in the model group were significantly decreased （P<0.05）， while the time indexes and other indexes were significantly increased （P<0.05）. The mRNA and protein expression levels of IL-17A， IL-17RA， Act1， and TRAF6 in pulmonary tissue and the positive expressions of downstream NF-κB p65， p-NF-κB p65， and p-p38 MAPK were increased （P<0.05）. Compared with the model group， the levels of IL-6， IL-8， IL-17， IL-1β， and TNF-α in the serum of all treatment groups were decreased to varying degrees （P<0.05）， and the indexes of pulmonary function were improved to different degrees （P<0.05）. The mRNA and protein levels of IL-17A， IL-17RA， Act1， and TRAF6 and the positive expression of downstream NF-κB p65， p-NF-κB p65， and p-p38 MAPK in high and medium-dose Xuanfei Zhisou prescription groups were significantly decreased （P<0.05）. ConclusionXuanfei Zhisou prescription can effectively resist inflammation of COPD rats. The mechanism may be related to down-regulating the protein expression of IL-17A， IL-17RA， Act1， and TRAF6， inhibiting downstream NF-κB and p38 MAPK signaling pathways， and reducing the release of IL-6， IL-8， TNF-α， IL-17， and IL-1β， thus reducing the airway inflammation response.

Objective:To investigate the value of 18F-FDG PET/CT combined with conventional imaging modalities in the evaluation of the depth of tumor invasion, regional lymph node metastasis, distant organ and lymph node metastasis (TNM staging), and the adjacent structure invasion of rectal cancer. Methods:Fifty-four patients (28 males, 26 females, age (65.8±11.0) years) with pathologically confirmed rectal cancer admitted to the Affiliated Qingdao Central Hospital of Qingdao University between September 2019 and June 2021 were retrospectively analyzed. 18F-FDG PET/CT examination, conventional imaging modalities including high-resolution MRI (HR-MRI), chest CT plain scan, upper abdominal MRI or CT plain scan+ enhanced examination were performed within 2 weeks before or after the rectal cancer being confirmed. The TNM staging and adjacent structural invasions including circumferential resection margin (CRM), extramural vascular invasion (EMVI), anal sphincter complex involvement were evaluated by 18F-FDG PET/CT and conventional imaging modalities separately or in combination, and those results based on imaging were compared with the pathological results or clinical follow-up results. χ2 test was used to compare the differences of diagnostic sensitivity, specificity and accuracy between the 18F-FDG PET/CT or conventional imaging modalities and combined examination. Results:The accuracy for T staging and the sensitivity and accuracy for N staging of the combined examination were 96.30%(52/54), 98.65%(73/74) and 93.91%(185/197), respectively, which were significantly higher than those of 18F-FDG PET/CT (85.19%(46/54), 66.22%(49/74), 81.73%(161/197); χ2 values: 3.97, 26.88, 13.66, all P<0.05). The specificity (91.06%, 112/123) and accuracy of the combined examination for N staging were higher than those of the conventional imaging modalities (77.24%(95/123), 83.76%(165/197); χ2 values: 8.81, 10.23, both P<0.05). The sensitivity and accuracy of the combined examination for M staging were higher than those of the conventional imaging modalities (97.01%(65/67) vs 73.13%(49/67), 95.95%(71/74) vs 68.92%(51/74); χ2 values: 15.05, 18.66, both P<0.001). The sensitivities of the combined examination in evaluating CRM and EMVI were 100%(22/22) and 95.00%(19/20), and the accuracies were 98.15%(53/54) and 96.30%(52/54), all of which were higher than those of 18F-FDG PET/CT (CRM: 54.55%(12/22), 74.07%(40/54); EVMI: 30.00%(6/20), 74.07%(40/54); χ2 values: 12.94, 13.08, 18.03, 10.56, all P<0.01). The accuracy of the combined examination in evaluating EMVI was higher than that of the conventional imaging modalities (85.19%(46/54); χ2=3.97, P=0.046). Conclusion:18F-FDG PET/CT combined with conventional imaging modalities can improve the diagnostic efficacy for TNM staging and assessment of adjacent structural invasion in rectal cancer.

Objective:To report the long-term outcomes of Chinese rectal cancer patients after adopting a Watch and Wait (W&W) strategy following neoadjuvant therapy (NAT).Methods:This multicenter, cross-sectional study was based on real-world data. The study cohort comprised rectal cancer patients who had achieved complete or near complete clinical responses (cCRs, near-cCRs) after NAT and were thereafter managed by a W&W approach, as well as a few patients who had achieved good responses after NAT and had then undergone local excision for confirmation of pathological complete response. All participants had been followed up for ≥2 years. Patients with distant metastases at baseline or who opted for observation while living with the tumor were excluded. Data of eligible patients were retrospectively collected from the Chinese Wait-and-Watch Data Collaboration Group database. These included baseline characteristics, type of NAT, pre-treatment imaging results, evaluation of post-NAT efficacy, salvage measures, and treatment outcomes. We herein report the long-term outcomes of Chinese rectal cancer patients after NAT and W&W and the differences between the cCR and near-cCR groups.Results:Clinical data of 318 rectal cancer patients who had undergone W&W for over 2 years and been followed up were collected from eight medical centers (Peking University Cancer Hospital, Fudan University Shanghai Cancer Center, Sun Yat-sen University Cancer Center, Shanghai Changhai Hospital, Peking Union Medical College Hospital, Liaoning Cancer Hospital, the First Hospital of Jilin University, and Yunnan Cancer Hospital.) The participants comprised 221 men (69.4%) and 107 women (30.6%) of median age 60 (26-86) years. The median distance between tumor and anal verge was 3.4 (0-10.4) cm. Of these patients, 291 and 27 had achieved cCR or near-cCR, respectively, after NAT. The median duration of follow-up was 48.4 (10.2-110.3) months. The 5-year cumulative overall survival rate was 92.4% (95%CI: 86.8%-95.7%), 5-year cumulative disease-specific survival (CSS) rate 96.6% (95%CI: 92.2%-98.5%), 5-year cumulative organ-preserving disease-free survival rate 86.6% (95%CI: 81.0%-90.7%), and 5-year organ preservation rate 85.3% (95%CI: 80.3%-89.1%). The overall 5-year local recurrence and distant metastasis rates were 18.5% (95%CI: 14.9%-20.8%) and 8.2% (95%CI: 5.4%-12.5%), respectively. Most local recurrences (82.1%, 46/56) occurred within 2 years, and 91.0% (51/56) occurred within 3 years, the median time to recurrence being 11.7 (2.5-66.6) months. Most (91.1%, 51/56) local recurrences occurred within the intestinal lumen. Distant metastases developed in 23 patients; 60.9% (14/23) occurred within 2 years and 73.9% (17/23) within 3 years, the median time to distant metastasis being 21.9 (2.6-90.3) months. Common sites included lung (15/23, 65.2%), liver (6/23, 26.1%), and bone (7/23, 30.4%) The metastases involved single organs in 17 patients and multiple organs in six. There were no significant differences in overall, cumulative disease-specific, or organ-preserving disease-free survival or rate of metastases between the two groups (all P>0.05). The 5-year local recurrence rate was higher in the near-cCR than in the cCR group (41.6% vs. 16.4%, P<0.01), with a lower organ preservation rate (69.2% vs. 88.0%, P<0.001). The success rates of salvage after local recurrence and distant metastasis were 82.1% (46/56) and 13.0% (3/23), respectively. Conclusion:Rectal cancer patients who achieve cCR or near-cCR after NAT and undergo W&W have favorable oncological outcomes and a high rate of organ preservation. Local recurrence and distant metastasis during W&W follow certain patterns, with a relatively high salvage rate for local recurrence. Our findings highlight the importance of close follow-up and timely intervention during the W&W process.

Objective To objectively evaluate the clinical efficacy and safety of acupuncture in regulating the mood of patients with post-stroke depression(PSD)and explore the possible target of acupuncture intervention.Methods 76 patients with PSD were randomly divided into treatment group and control group.The control group was treated with routine treatment measures for stroke,and the treatment group was treated with acupuncture on this basis.The main acupoints were Shangxing,Baihui,Shenting,Fengchi and Dugu,supplemented by acupuncture on Taichong,Hegu,Quchi,Neiguan,Yanglingquan,Zusanli and Taixi,5 times a week,continuously treated for 4 weeks,followed up on the 90th day after treatment.The levels of serum 5-hydroxytryptamine,norepinephrine and intestinal microflora before and after treatment were compared with the 17 Hamilton Depression Scale scores(HAMD),modified Barthel Index(MBI),and the levels of serum 5-hydroxytryptamine and norepinephrine before and after treatment.Results The HAMD score and MBI index of the two groups after treatment and follow-up were lower than those before treatment.The levels of 5-hydroxytryptamine and norepinephrine in the treatment group after treatment were higher than those before treatment(P<0.01),and significantly higher than those in the control group(P<0.01).After acupuncture,the dominant bacterial groups of Bacteroides,Thick-wall bacteria and Broughter bacteria in patients showed an upward trend(P>0.05).The difference of bacteria before and after treatment was mainly concentrated in signal pathways such as ECM-receptor interaction,and the difference was statistically significant(P<0.01).Conclusion Acupuncture can help patients improve their ability of daily living,and also improve the relative abundance of intestinal flora in PSD patients to a certain extent,so as to regulate the levels of 5-HT and NE to relieve the depression of patients,which is worthy of promotion in clinical practice.

Systemic mastocytosis (SM) with RUNX1-RUNX1T1 positive acute myeloid leukemia (AML) is a rare myeloid tumor with no standard treatment. Two cases of SM patients with RUNX1-RUNX1T1 positive AML treated with sequential avapritinib after allogeneic hematopoietic stem cell transplantation (allo-HSCT) were reported in Henan Cancer Hospital. Mast cell in bone marrow disappeared, C-KIT mutation and RUNX1-RUNX1T1 fusion gene remained negative. Allo-HSCT sequential avapritinib is an effective treatment for SM patients with RUNX1-RUNX1T1 positive AML.

Objective:To investigate the efficacy and safety of avapritinib in the treatment of molecular biologically positive core binding factor-acute myeloid leukemia (CBF-AML) with KIT mutation after allogeneic hematopoietic stem cell transplantation (allo-HSCT) .Methods:We retrospectively analyzed the clinical data of six patients with molecular biologically positive CBF-AML with KIT mutation after allo-HSCT, who were treated with avapritinib at Henan Cancer Hospital from December 2021 to March 2023, and evaluated the efficacy and safety of avapritinib.Results:After 1 month of treatment with avapritinib, the transcription level of the fusion gene decreased in six patients, and the transcription level decreased by ≥1 log in five patients. In four patients who received avapritinib for ≥3 months, the fusion gene turned negative, and the median time to turn negative was 2.0 (range: 1.0-3.0) months. Up to the end of follow-up, four patients had no recurrence. The most common adverse reaction of avapritinib was myelosuppression, including neutropenia in two cases, thrombocytopenia in two cases, and anemia in one case. The non-hematological adverse reactions were nausea in two cases, edema in one case, and memory loss in one case, all of which were grades 1-2.Conclusion:Avapritinib was effective for molecular biologically positive CBF-AML patients with KIT mutation after allo-HSCT. The main adverse reaction was myelosuppression, which could generally be tolerated.

Rheumatoid arthritis is a chronic, systemic autoimmune disease predominantly based on joint lesions with an extremely high disability and deformity rate. Several drugs have been used for the treatment of rheumatoid arthritis, but their use is limited by suboptimal bioavailability, serious adverse effects, and nonnegligible first-pass effects. In contrast, transdermal drug delivery systems (TDDSs) can avoid these drawbacks and improve patient compliance, making them a promising option for the treatment of rheumatoid arthritis (RA). Of course, TDDSs also face unique challenges, as the physiological barrier of the skin makes drug delivery somewhat limited. To overcome this barrier and maximize drug delivery efficiency, TDDSs have evolved in terms of the principle of transdermal facilitation and transdermal facilitation technology, and different generations of TDDSs have been derived, which have significantly improved transdermal efficiency and even achieved individualized controlled drug delivery. In this review, we summarize the different generations of transdermal drug delivery systems, the corresponding transdermal strategies, and their applications in the treatment of RA.

Objective     To investigate the current status of constipation during postoperative hospitalization and the factors associated with moderate to severe constipation at discharge in lung cancer patients. Methods     Lung cancer patients who underwent surgery in 6 tertiary hospitals in Sichuan Province from November 2017 to January 2020 were enrolled. The MD Anderson Symptom Scale-Lung Cancer Module was used to collect postoperative constipation scores. Unconditional logistic stepwise regression was used to analyze the related influencing factors for moderate to severe constipation on the day of discharge. Results     Finally 337 patients were collected. There were 171 males and 166 females, with an average age of 55.0±10.3 years. Constipation scores of lung cancer patients increased from postoperative day 1 to day 3, and showed a decreasing trend from day 3 to day 7. Moderate to severe constipation was present in 68 (20.2%) patients at discharge. The postoperative hospital stay (OR=0.743, P<0.001) and the dose of morphine used during postoperative hospitalization (OR=1.002, P=0.015) were influencing factors for moderate to severe constipation at discharge in lung cancer patients. Conclusion    Lung cancer patients have the most severe constipation on postoperative day 3. Moderate to severe constipation at discharge is associated with the postoperative hospital stay and the dose of morphine used during postoperative hospitalization.
