OBJECTIVE To evaluate the clinical efficacy of Chaihu anxin capsules in the treatment of mild-to-moderate depression， analyze the influencing factors of its efficacy, construct a nomogram prediction model.METHODS Patients with mild-to-moderate depression treated at The First Hospital of Hebei Medical University from May 1， 2023 to March 10， 2025 were retrospectively included and categorized into Chaihu anxin capsules group and milnacipran group according to treatment regimen. Propensity score matching （PSM） was used to balance baseline characteristics， and treatment efficacy was compared after 8 weeks， including 24 Hamilton Depression Scale （HAMD-24） scores and changes， Hamilton Anxiety Scale （HAMA） scores and changes， and treatment response rate after 8 weeks of treatment. Patients receiving Chaihu anxin capsules were further classified as responders or non-responders based on the occurrence of treatment response. Univariate and multivariate Logistic regression analyses were conducted to identify the influencing factors of treatment response， and a nomogram model was constructed to predict the probability of treatment response， its predictive performance was evaluated using receiver operating characteristic （ROC） curves， calibration curves， and decision curve analysis.RESULTS A total of 297 patients were included before PSM， including 196 patients in the Chaihu anxin capsules group and 101 patients in the milnacipran group. After PSM， each group included 44 patients. After PSM， the HAMD-24 scores and HAMA scores at 8 weeks after treatment in the Chaihu anxin capsules group， as well as the HAMD-24 scores in the milnacipran group， were significantly lower than their respective baseline values （ P ＜0.05）； the change in HAMA score in the Chaihu anxin capsules group was significantly greater than that in the milnacipran group （ P ＝0.04）. Multivariable Logistic regression identified age， total bilirubin， and baseline HAMD-24 score as independent predictors of treatment response （ P ＜0.05）. The area under the ROC curve of the constructed nomogram prediction model was 0.72 （95% confidence interval： 0.637-0.799）， and the corrected Brier score was 0.143 （95% confidence interval： 0.112-0.176）； compared with the “all intervention” and “all non intervention” strategies， applying this nomogram prediction model could achieve higher net benefits within the threshold probability range of 8% to 37%.CONCLUSIONS The efficacy of Chaihu anxin capsules in improving mild-to-moderate depression is comparable to that of milnacipran， and it has certain advantages in improving anxiety symptoms； age， total bilirubin， and baseline HAMD-24 score are independent influencing factors for the treatment response of Chaihu anxin capsules. The nomogram prediction model constructed based on these factors has good discrimination， calibration， and clinical applicability.

Objective:This study evaluated the efficacy of the PST technique: Preservation of the left colic artery (P), suture reinforcement (S), and transanal tube (T) combined with selective fecal diversion via end ileostomy, in preventing anastomotic leakage following laparoscopic anterior resection (LAR) for mid-to-low rectal cancer.Methods:We retrospectively collected data for this descriptive case series from patients who underwent laparoscopic LAR with complete or partial application of the PST technique, some of whom received prophylactic ileostomy, at the Department of Colorectal Surgery, Zhongshan Hospital Affiliated to Fudan University, and its Xiamen Branch between July, 2022 and December, 2024. "Partial PST" was defined as the implementation of PS (Preservation of the left colic artery + suture reinforcement), PT (Preservation of the left colic artery + transanal tube), ST (suture reinforcement + transanal tube), or a single T procedure (Transanal tube). The primary outcome measures were the proportion of patients who received the PST technique and terminal ileostomy, as well as the incidence of anastomotic leaks.Results:Among 198 patients, 145 received complete PST. Fifty-three patients underwent partial PST (PT) because anastomotic reinforcement was not feasible due to an excessively low anastomosis or obesity. All patients achieved R0 resection. Postoperative pathology showed that 108 patients (54.5%) were at T3-T4 stage, and 81 patients (40.9%) had poorly differentiated adenocarcinoma or mucinous adenocarcinoma. A total of 19.7% (39/198) of patients developed grade II or higher postoperative complications, including 11 cases (5.6%) of surgical site infection and 7 cases (3.5%) of urinary retention. Five patients were rehospitalized within 30 days after surgery, among whom 2 had intestinal obstruction, and 3 developed grade C anastomotic leaks that required reoperation for salvage enterostomy. The overall incidence of anastomotic leakage was 3.0% (6/198). Fifty-three patients (26.8%) received protective ileostomy, with an anastomotic leak incidence of 1.9% (1/53). Methylene blue leakage occurred in 20 patients (10.1%), all of whom received prophylactic ileostomy and had no anastomotic leakage postoperatively. Among 61 patients who received neoadjuvant chemoradiotherapy before surgery, 28 underwent prophylactic ileostomy, and none developed anastomotic leaks after surgery.Conclusions:Routine application of the PST technique during laparoscopic low anterior resection, along with prophylactic enterostomy for ultra-high-risk populations, can effectively control the incidence of anastomotic leakage.

Objective To investigate the effect of circFOXK2 on the proliferation,migration and invasion of lung cancer cells and its possible mechanism.Methods The cancer tissues and adjacent tissues of 45 patients with lung cancer were collect-ed,and the expression of circFOXK2 and miR-409-3p in the tissues were detected by qRT-PCR.Lung cancer cell A549 and H1299 was cultured in vitro,and the dual-luciferase reporter assay was used to verify the regulatory relationship between circ-FOXK2 and miR-409-3p.The CCK-8,clone formation and Transwell assays were used to detect cell proliferation,migration and invasion.Western blot was used to detect the protein expression of E-cadherin and N-cadherin in cells.Results The expression of circFOXK2 was significantly higher(P＜0.05),but the expression of miR-409-3p was significantly lower(P＜0.05)in lung cancer tissues.circFOXK2 could target miR-409-3p and negatively regulate its expression in lung cancer cells.The proliferation,migration and invasion were reduced in circFOXK2(all P＜0.05),N-cadherin level was decreased(P＜0.05),but E-cadherin level was increased(P＜0.05)in circFOXK2 knockdown or miR-409-3p overexpressed A549 and H1299 cells.The inhibitory effects of circFOXK2 knockdown on the proliferation,migration and invasion of lung cancer cells could be reversed by miR-409-3p inhibitor.Conclusion The circFOXK2 was upregulated in lung cancer,which promoted the proliferation,migration and inva-sion of lung cancer cells by targeting miR-409-3p.

The lung is the second most common site of neuroendocrine tumors (NETs). Typical and atypical carcinoids are low-grade NETs of the lung. These rare tumors have received little attention and education is needed for treating physicians. The article describes the classifcation of lung NETs, the epidemiology and pathological characteristics. When lung NETs are diagnosed at an early stage, surgical intervention is often curative. For advanced lung NETs patients, different treatment methods including chemotherapy, somatostatin analogs, m-TOR inhibition, peptide receptor radioligand therapy, and biologic systemic therapy are discussed. The conclusions are generally extrapolated from the outcome of extra-pulmonary carcinoids. Prospective randomized well-designed trials are urgently needed to inform current recommendations on systemic treatment.

Objective: To study the antiseptic effect of compound lysostaphin disinfectant and its preventive effect on infection of artificial dermis after graft on full-thickness skin defect wound in rats. Methods: (1) Each one standard strain of Klebsiella pneumoniae, Acinetobacter baumannii, and Staphylococcus aureus were selected. Each 20 clinical strains of Klebsiella pneumoniae, Acinetobacter baumannii, and Staphylococcus aureus were collected from those isolated from wound exudates of burn patients hospitalized in our wards from January 2014 to December 2016 according to the random number table. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of compound lysostaphin disinfectant to above-mentioned strains were detected. The experiment was repeated 3 times. Compared with the corresponding standard strain, the clinical strain with higher MIC and/or MBC was considered as having decreased sensitivity to the disinfectant. The percentage of strains of each of the three kinds of bacteria with decreased sensitivity was calculated. (2) Artificial dermis pieces were soaked in compound lysostaphin disinfectant for 5 min, 1 h, 2 h, and 4 h, respectively, with 21 pieces at each time point. After standing for 0 (immediately), 12, 24, 36, 48, 60, 72 h (with 3 pieces at each time point), respectively, the diameters of their inhibition zones to standard strains of Klebsiella pneumoniae, Acinetobacter baumannii, and Staphylococcus aureus were measured. The experiment was repeated 3 times. The shortest soaking time corresponding to the longest standing time, after which the disinfectant-soaked artificial dermis could form an effective inhibition zone (with diameter more than 7 mm), was the sufficient soaking time of the disinfectant to the artificial dermis. (3) Forty Sprague-Dawley rats were divided into post injury day (PID) 3, 7, 14, and 21 sampling groups according to the random number table, with 10 rats in each group. A full-thickness skin defect wound with a diameter of 20 mm was made on both sides of the spine on the back of each rat. Immediately after injury, the artificial dermis without any treatment was grafted on the wound on left side of the spine (hereinafter referred to as control wound), while the sufficiently soaked artificial dermis with compound lysostaphin disinfectant was grafted on the wound on right side of the spine (hereinafter referred to as disinfectant wound). On PID 3, 7, 14, and 21, the gross condition of wounds of all the surviving rats was observed, and the new infection rates of control wounds and disinfectant wounds were calculated. Then, the rats in the sampling group with corresponding time were killed, and the full-thickness wound tissue containing artificial dermis was collected for quantitative analysis of bacteria. Bacteria content of the uninfected control wounds and that of the uninfected disinfectant wounds were compared. Data were processed with chi-square test and Wilcoxon rank sum test. Results: (1) The MIC of compound lysostaphin disinfectant to standard strains of Staphylococcus aureus, Klebsiella pneumoniae, and Acinetobacter baumannii were 1/32, 1/32, and 1/512 of the original concentration of the disinfectant, respectively, and the MBC were 1/32, 1/16, and 1/512 of the original concentration of the disinfectant, respectively. The percentages of clinical strains of Klebsiella pneumoniae, Acinetobacter baumannii and Staphylococcus aureus with decreased sensitivity to compound lysostaphin disinfectant were 15% (3/20), 20% (4/20), and 10% (2/20), respectively. (2) After being soaked in compound lysostaphin disinfectant for 2 and 4 h, the longest standing time, after which the artificial dermis could form an effective inhibition zone against Klebsiella pneumoniae, Acinetobacter baumannii, and Staphylococcus aureus, were 24, 36, and 48 h respectively, longer than 12, 24, and 24 h of soaking for 5 min and 24, 24, and 36 h of soaking for 1 h. The sufficient soaking time of compound lysostaphin disinfectant to artificial dermis was 2 h. (3) On PID 3, no infection symptom was observed in all the wounds, and so both the new infection rate of control wounds and that of disinfectant wounds were 0. The artificial dermis was transparent but not well connected with the wound. On PID 7, the new infection rate of control wounds was 20.00% (6/30), which was obviously higher than 3.33% (1/30) of disinfectant wounds, χ²=4.043, P<0.05. On the infected wound, a large amount of purulent exudates were observed, and the artificial dermis was not connected with the wound and degraded partially. On the uninfected wound, artificial dermis was transparent and had a partial connection with the wound. On PID 14 and 21, no new infected wound was observed, and so both the new infection rate of control wounds and that of disinfectant wounds were 0. There was no obvious improvement on the infected wounds. The collagen layers of artificial dermis in the uninfected wound established a good connection with the wound and were separating from the silica gel layer gradually. Infection occurred in 2, 3, 1 control wound (s) in PID 7, 14, and 21 sampling groups, respectively, and in 1 disinfectant wound in PID 14 sampling group. The bacteria content of the infected wounds tissue was 0.79×10⁶ to 7.22×10⁹ colony-forming unit (CFU)/g. The bacteria content of uninfected control wounds tissue in PID 3, 7, and 14 sampling groups were (3.43±1.88)×10^2, (2.37±0.43)×10^3, and (8.40±1.03)×10³ CFU/g, respectively, which were significantly higher than (0.33±0.12)×10^2, (0.43±0.17)×10^3, (2.16±0.52)×10³ CFU/g of uninfected disinfectant wounds tissue (Z=-3.780, -3.554, -3.334, P<0.05). The bacteria content of uninfected control wounds tissue and that of uninfected disinfectant wounds tissue in PID 21 sampling group were similar (Z=-0.490, P>0.05). Conclusions Compound lysostaphin disinfectant has quite strong antibacterial ability against Klebsiella pneumoniae, Acinetobacter baumannii, and Staphylococcus aureus. Clinical strains of the three kinds of bacteria were highly sensitive to compound lysostaphin disinfectant. Saturation of absorption of compound lysostaphin disinfectant achieves in artificial dermis after 2 hours′ soaking. After 24, 36, and 48 hours′ standing, the soaked artificial dermis still has the antibacterial effect on Klebsiella pneumoniae, Acinetobacter baumannii, and Staphylococcus aureus, respectively. The infection rate and the bacteria content of full-thickness skin defect wound in rats are all decreased when grafted with soaked artificial dermis.
