Traditional Chinese medicine (TCM) is a well-accepted therapy for atopic dermatitis (AD). However, there are currently no evidence-based guidelines integrating TCM and Western medicine for the treatment of AD, limiting the clinical application of such combined approaches. Therefore, the China Association of Chinese Medicine initiated the development of the current guideline, focusing on key issues related to the use of TCM in the treatment of AD. This guideline was developed in accordance with the principles of the guideline formulation manual published by the World Health Organization. A comprehensive review of the literature on the combined use of TCM and Western medicine to treat AD was conducted. The findings were extensively discussed by experts in dermatology and pharmacy with expertise in both TCM and Western medicine. This guideline comprises 23 recommendations across seven major areas, including TCM syndrome differentiation and classification of AD, principles and application scenarios of TCM combined with Western medicine for treating AD, outcome indicators for evaluating clinical efficacy of AD treatment, integration of TCM pattern classification and Western medicine across disease stages, daily management of AD, the use of internal TCM therapies and proprietary Chinese medicines, and TCM external treatments.

Objective:To evaluate the clinical value and safety of an intraperitoneal chemotherapy port technique in patients with gastric cancer and peritoneal metastases undergoing intraperitoneal chemotherapy.Methods:This was a retrospective, descriptive case analysis. From November 2022 to October 2024, patients diagnosed with gastric cancer and peritoneal metastases at Wuxi Branch of Ruijin Hospital, Shanghai Jiao Tong University School of Medicine with an expected survival >3 months, underwent laparoscopic exploration combined with implantation of an intraperitoneal chemotherapy port [PORT-A-CATH II system (Model 21-4055-24)] implantation. The procedure was as follows: (1) after laparoscopic exploration, a 4-cm skin incision was made at a predetermined site and a subcutaneous pocket created by dissecting to the muscle fascia and removing subcutaneous fat as needed to position the port septum 0.5-1.0 cm from the skin surface; (2) under direct laparoscopic visualization, the abdominal cavity was punctured and a guidewire inserted, followed by an 8.5 Fr sheath, through which a catheter with three trimmed side holes was placed after removal of the sheath; (3) the catheter length in the abdominal cavity was adjusted to 25–30 cm and the catheter trimmed, and connected to the port base, ensuring it extended beyond the connector's visible hole; (4) the whole port was placed within the subcutaneous pocket, and non-absorbable sutures used to create a double purse-string suture at the catheter's abdominal entry, forming an anti-reflux ring; (5) non-absorbable sutures were used to securely fix the port to the fascia through its four base holes and the exposed catheter segments on the fascia sutured and buried; (6) patency was confirmed by injecting saline and followed by intermittent skin closure provided there was no bleeding; and (7) the catheter tip was positioned in the pelvic cavity under laparoscopic guidance. Postoperatively, the patients underwent normothermic intraperitoneal and systemic treatment. The port infusion protocol involved disinfecting the skin (>10 cm diameter) around the port, confirming the puncture site, inserting a Huber needle vertically at 90° to the port base, infusing 100 mL saline to ensure patency, followed by continuous infusion of 1000 mL paclitaxel solution, and sealing with 20 mL saline before removing the needle. No saline flushing was required between chemotherapy infusions. The primary outcomes were the incidence and management of complications post-port implantation.Results:The study cohort comprised 225 patients with gastric cancer and peritoneal metastases. Using standardized port implantation and postoperative puncture procedures, the complication rate during follow-up was 14.2% (32/225), including effusion in 14 patients (6.2%), port infection in 10 (4.4%), incision dehiscence in four (1.8%), port inversion in two (0.9%), hematoma in one (0.4%), and catheter rupture in one (0.4%). Seventy-five percent (24/32) of patients with complications recovered and continued using the port after conservative treatments (e. g., aspiration of effusions, antibiotic therapy, incision management), whereas the remaining 25.0% (8/32) with complications required surgical removal of the port because the treatment was ineffective. The presence of preoperative ascites ( P=0.019) and peritoneal cancer index score>15 ( P=0.038) were significantly associated with development of complications. Conclusions:Our standardized procedure for intraperitoneal chemotherapy port implantation is safe and feasible for patients with gastric cancer and peritoneal metastases, having a low overall complication rate. Most complications can be successfully managed with conservative treatment, the device thus providing reliable support for intraperitoneal chemotherapy.

This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations. Observationally, a history of gallstones without cholecystectomy was associated with a high risk of stomach cancer (adjusted odds ratio (aOR)=2.54, 95% confidence interval (CI) 1.50-4.28), liver and bile duct cancer (aOR=2.46, 95% CI 1.17-5.16), kidney cancer (aOR=2.04, 95% CI 1.05-3.94), and bladder cancer (aOR=2.23, 95% CI 1.01-5.13) in the general population, as well as cervical cancer (aOR=1.69, 95% CI 1.12-2.56) in women. Moreover, cholecystectomy was associated with high odds of stomach cancer (aOR=2.41, 95% CI 1.29-4.49), colorectal cancer (aOR=1.83, 95% CI 1.18-2.85), and cancer of liver and bile duct (aOR=2.58, 95% CI 1.11-6.02). MR analysis only supported the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer. This study added evidence to the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer, highlighting the importance of cancer screening in individuals with gallstones.

Objective:To evaluate the safety and validity of perioperative antimicrobial prophylaxis with different administration period in patients undergoing transurethral resection of the prostate (TURP) for benign prostatic hyperplasia (BPH).Methods:This prospective randomized controlled clinical trial was conducted on patients who underwent TURP in the Second Affiliated Hospital of Anhui Medical University from July 2022 to December 2023. The patients were randomly assigned to the experimental group and the control group in a 1∶1 ratio using a randomized block design. Inclusion criteria: age 55-78 years old, the indication of benign prostatic hyperplasia surgery, preoperative urine routine examination showed no pyuria or bacteriuria, preoperative catheterization being not reserved, postoperative pathology confirmed BPH and informed consent obtained. Exclusion criteria: severe heart, lung, brain and other diseases which could not tolerate anesthesia and surgery, complicated with bladder stones or bladder tumors, diabetic patients with poor glycemic control, immunosuppressive agents being administered. Patients in the experimental group received a single dose of cephalosporins or fluoroquinolones 30 minutes or 2 hours before surgery, while patients in the control group received a second dose 12 hours or 24 hours after the first dose. The primary outcome was the incidence of urinary tract infectious presenting fever (body temperature ≥38.5℃) within 1 week after surgery, while the white blood cell count, C-reactive protein concentration, serum heparin-binding protein concentration, red and white blood cell count in urine, the incidence of bacteriuria, pulmonary infection, and postoperative hospital stay were defined as secondary outcomes. The safety index was the incidence of adverse reactions of antibiotics.Results:A total of 180 patients were enrolled in this study, including 90 cases in each experimental group or control group. Two groups of patients had no significant difference ( P>0.05) in age [(71.7±3.9) and (69.9±4.8) years], prostate volume [55.0 ml(39.5, 62.0) and 52.5(45.5, 68.5) ml], operation time [(58.8±17.0) min vs. (60.9±16.7) min], and postoperative indwelling catheter days [3.0(3, 4) d vs. 3.8(3, 4) d]. The incidence of fever within 1 week after surgery was 7.8%(7/90) in the experimental group and 5.6%(5/90) in the control group, respectively, and the difference was not statistically significant ( P=0.550). Our data demonstrated that the white blood cell count [(10.5±1.2)×10 9/L vs. (9.7±4.1)×10 9/L], C-reactive protein concentration [(43.0±27.9) mg/L vs. (53.1±29.9) mg/L] and heparin-binding protein concentration [(44.7±19.4) ng/ml vs. (37.8±23.5) ng/ml], urine red blood cell count [4 768.2(2 387.9, 10 496.5)/μl vs. 6 577.2(3 691.5, 7 636.8) /μl], urine white blood cell count [447.1(283.9, 637.0)/μl vs 242.8(109.7, 691.8)/μl] were mildly elevated in two groups without significant difference ( P>0.05). The incidence of postoperative pulmonary infection [3.3% (3/90)] vs. 2.2% (2/90)], bacteriuria [6.7% (6/90) vs. 8.9% (8/90)], postoperative hospital stay [4.5(4.0, 5.1) days vs. 4.5(4.0, 5.5) days] also showed no significant difference ( P>0.05). While the incidence of adverse reactions of antibiotics in the experimental group 3.3% (3/90) was significantly lower than that in the control group 11.1% (10/90) ( P=0.044). Conclusions:A single-dose antibiotic administration as a perioperative antimicrobial prophylaxis is safe and effective for patients undergoing TURP who do not have preoperative pyuria or indwelling catheter.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in healthcare facilities in major regions of China in 2023.Methods Clinical isolates collected from 73 hospitals across China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2023 Clinical & Laboratory Standards Institute (CLSI) breakpoints.Results A total of 445199 clinical isolates were collected in 2023,of which 29.0% were gram-positive and 71.0% were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species (excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi) (MRSA,MRSE and MRCNS) was 29.6%,81.9% and 78.5%,respectively.Methicillin-resistant strains showed significantly higher resistance rates to most antimicrobial agents than methicillin-susceptible strains (MSSA,MSSE and MSCNS).Overall,92.9% of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 91.4% of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis had significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 93.1% in the isolates from children and and 95.9% in the isolates from adults.The resistance rate to carbapenems was lower than 15.0% for most Enterobacterales species except for Klebsiella,22.5% and 23.6% of which were resistant to imipenem and meropenem,respectively .Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.6% to 10.0%.The resistance rate to imipenem and meropenem was 21.9% and 17.4% for Pseudomonas aeruginosa,respectively,and 67.5% and 68.1% for Acinetobacter baumannii,respectively.Conclusions Increasing resistance to the commonly used antimicrobial agents is still observed in clinical bacterial isolates.However,the prevalence of important crabapenem-resistant organisms such as crabapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a slightly decreasing trend.This finding suggests that strengthening bacterial resistance surveillance and multidisciplinary linkage are important for preventing the occurrence and development of bacterial resistance.

Objective:To observe and evaluate the clinical efficacy and safety of albumin-bound paclitaxel as first-line treatment for patients with advanced pancreatic cancer in China, and to explore the prognosis-related molecules in pancreatic cancer based on next-generation sequencing (NGS) of tumor tissues.Methods:From December 2018 to December 2020, patients with locally advanced or metastatic pancreatic cancer were recruited to accept albumin-bound paclitaxel as first-line treatment in the oncology departments of 24 hospitals in East China. The primary endpoints were overall survival (OS) and treatment related adverse events, and the secondary endpoint was progression-free survival (PFS). Adverse effects were graded using Common Terminology Criteria for Adverse Events 5.0 (CTCAE 5.0). NGS sequencing on the primary or metastatic tissue samples of pancreatic cancer obtained through surgical resection or biopsy was performed.Results:This study recruited 229 patients, including 70 patients with locally advanced pancreatic cancer (LAPC) and 159 patients with metastatic pancreatic cancer (mPC). The disease control rate was 79.9% and the objective response rate is 36.3%.The common adverse effects during treatment were anaemia (159 cases), leucopenia (170 cases), neutropenia (169 cases), increased aminotransferases (110 cases), and thrombocytopenia (95 cases), and the incidence of grade 3-4 neutropenia is 12.2% (28/229). The median follow-up time was 21.2 months (95% CI: 18.5-23.1 months). The median PFS (mPFS) was 5.3 months (95% CI: 4.37-4.07 months) and the median OS (mOS) was 11.2 months (95% CI: 9.5-12.9 months). The mPFS of patients with LAPC was 7.4 months (95% CI: 6.6-11.2 months), and their mOS was 15.5 months (95% CI: 12.6-NA months). The mPFS of patients with mPC was 3.9 months (95% CI: 3.4-5.1 months), and their mOS was 9.3 months (95% CI: 8.0-10.8 months). Multivariate Cox regression analysis showed that clinical stage ( HR=1.47, 95% CI: 1.06-2.04), primary tumor site ( HR=0.64, 95% CI: 0.48-0.86), Eastern Cooperative Oncology Group Performance Status (ECOG PS) score ( HR=2.66, 95% CI: 1.53-4.65), and whether to combine radiotherapy ( HR=0.65, 95% CI: 0.42-1.00) were independent influencing factors for the PFS of these patients. The primary tumor site ( HR=0.68, 95% CI: 0.48-0.95), ECOG score ( HR=5.82, 95% CI: 3.14-10.82), and whether to combine radiotherapy ( HR=0.58, 95% CI: 0.35-0.96) were independent influencing factors of the OS of these patients. The most frequent gene mutations in these advanced stage pancreatic patients were KRAS (89.66%), TP53 (77.01%), CDKN2A (32.18%), and SMAD4 (21.84%) by NGS of tumor tissues from 87 pancreatic cancer patients with sufficient specimens. Further analysis revealed that mutations in CDKN2B, PTEN, FGF6, and RBBP8 genes were significantly associated with an increased risk of death ( P<0.05). Conclusion:Albumin-bound paclitaxel as first-line treatment demonstrated feasible anti-tumor efficacy and manageable safety for patients with advanced pancreatic cancer in China.
