ObjectiveTo evaluate the clinical efficacy and safety of Xiaozhen Formula （消疹方） in preventing skin toxicity induced by epidermal growth factor receptor inhibitors （EGFRIs） in patients with EGFR-mutant non-small cell lung cancer （NSCLC）. MethodsA randomized， double-blind， placebo-controlled， multicenter clinical study was conducted. A total of 120 patients with EGFR-mutant NSCLC from seven centers were enrolled and randomly assigned to a treatment group （60 cases） or a control group （60 cases）. On the basis of EGFRI-targeted therapy， patients in the treatment group received Xiaozhen Formula granules， whereas those in the control group received Xiaozhen Formula placebo granules， both at 10 g twice daily for 4 consecutive weeks. The primary outcomes were the grading of skin toxicity evaluated using the National Cancer Institute Common Terminology Criteria for Adverse Events （NCI-CTCAE） version 5.0 and the incidence of rash. Secondary outcomes included the time to onset and time to resolution of the highest-grade rash， the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 （EORTC QLQ-C30） scores， the Hospital Anxiety and Depression Scale （HADS） scores， and disease control rate， together with safety assessments. ResultsBased on the full analysis set （FAS）， the incidence of skin toxicity in the treatment group was 18.33% （11/60）， significantly lower than 45.00% （27/60） in the control group （P＜0.01）， with the highest severity of skin toxicity in both groups was grade 2. Among patients who developed rash， the resolution rate in the treatment group was 90.91% （10/11）， higher than that 33.33% （9/27） in the control group. The median time to resolution was 15 days （95%CI： 8-17 days） in the treatment group and it was not reached in the control group； the distribution of time to resolution differed significantly between groups （P＜0.001）. After treatment， the treatment group had higher EORTC QLQ-C30 functional scale and global health status/quality-of-life scores， and lower symptom scale， single-item scores， as well as HADS-A， and HADS-D scores than the control group （P＜0.05）. In the FAS analysis， the disease control rate （DCR） was 85.0% （51/60） in the treatment group， lower than 100.0% （60/60） in the control group （P=0.003）， whereas no significant between-group difference was observed in the per-protocol set （PPS） analysis （P=0.464）. The incidence of adverse events did not differ significantly between the two groups （P＞0.05）， and no definite safety signals related to the investigational drug were observed. ConclusionXiaozhen Formula can reduce the incidence of EGFRI-induced skin toxicity， and improve the outcome of rash regression， the patients' quality of life and psychological status in EGFR-mutant NSCLC patients.

Objective To analyze the infection status and epidemic trends of soil-borne nematode infections in Yubei, Chongqing City, in 2010,2021, and 2022. Methods The local populations from four survey sites of four towns in 2010 and five sites of five towns in 2021 and 2022 were surveyed regarding their basic information using a unified form. Fecal samples of the participants were collected and tested for soil-borne nematode infections using the modified Kato-Katz thick smear method. Results In 2010, 2 049 participants were surveyed, followed by 1 000 participants in 2021 and 2022. The overall prevalence of parasitic infections declined significantly from 3.86% to 0.20%. In 2010, soil-transmitted nematode included hookworms(3.81%) and roundworms(0.29%). In 2021, the infection rates of roundworms and hookworms were 1.70% and 0.10% respectively. Notably, only Ascaris was identified in 2022(0.20%). The≥60 age group consistently exhibited the highest infection rates across all surveys, followed by the 40-59 age group. The infection rates of males in the three surveys were 3.31%,1.92%, and 0.20% respectively, and those of females were 4.37%, 1.46%, and 0.20% respectively. There was no statistically significant difference in the infection rates between males and females. Educational attainment was inversely associated with infection; in 2010, the highest prevalence was observed among those with primary education or below, whereas in 2021, illiterate or semi-literate individuals showed the highest susceptibility. The occupational distribution of infections in 2010 indicated that retirees (8.33%), farmers(4.86%), and homemakers or unemployed individuals(3.45%)were the most affected. However, in 2021 and 2022, farmers emerged as the predominant occupational group with soil-transmitted nematode infections. Conclusions The infection rate of soil-borne nematodes showed a decreasing trend in Yubei, and the infection species changed from hookworms in 2010 to Ascaris in 2022. Farmers, the elderly, and people with low education levels should continue to be the focus of preventive and control efforts.

Objective To observe the effects of Qigui Buxue Decoction combined with timed press-needle therapy on myelosuppression and cancer-related fatigue in chemotherapy patients with non-small cell lung cancer(NSCLC)of lung-spleen qi deficiency type.Methods A total of 124 NSCLC patients with lung-spleen qi deficiency type admitted to the Department of Radiotherapy and Chemotherapy at Cangzhou Integrated Traditional Chinese and Western Medicine Hospital in Hebei Province from January 2022 to June 2024 were selected as the study subjects.The patients were randomly divided into an observation group and a control group using a random number table,with 62 cases in each group.Both groups received platinum-based two-drug combination chemotherapy.The control group received timed press-needle therapy in addition to chemotherapy,while the observation group received Qigui Buxue Decoction in addition to the control group's treatment.The treatment course was 3 weeks,with a total of 2 courses.After 2 courses of treatment,changes in blood routine,lymphocyte subsets(CD3+,CD4+,CD8+,NK cells),CD4+/CD8+ratio,and the incidence of myelosuppression were observed.Changes in Piper Fatigue Scale and Karnofsky Performance Scale(KPS)scores before and after treatment were compared between the two groups.Results(1)After treatment,the white blood cell count in the observation group significantly improved(P＜0.05),and the observation group showed significantly better improvement in white blood cell count compared to the control group,with a statistically significant difference(P＜0.05).(2)After treatment,the levels of CD3+,CD4+,CD4+/CD8+,and NK cells in both groups significantly improved(P＜0.05),and the observation group showed significantly better improvement in these levels compared to the control group,with a statistically significant difference(P＜0.05).(3)The incidence of myelosuppression in the observation group was 58.06%(36/62),while it was 77.42%(48/62)in the control group.The incidence of myelosuppression in the observation group was significantly lower than that in the control group,with a statistically significant difference(P＜0.05).(4)After treatment,the Piper Fatigue Scale scores,including behavioral,emotional,physical,and total scores,significantly improved in both groups(P＜0.05),and the observation group showed significantly better improvement in these scores compared to the control group,with a statistically significant difference(P＜0.05).The cognitive scores of the Piper Fatigue Scale showed slight improvement in both groups,but there was no statistically significant difference compared to before treatment(P＞0.05).(5)After treatment,the KPS scores and TCM syndrome scores significantly improved in both groups(P＜0.05),and the observation group showed significantly better improvement in these scores compared to the control group,with a statistically significant difference(P＜0.05).Conclusion Qigui Buxue Decoction combined with timed press-needle therapy can effectively improve myelosuppression,enhance immune function,and alleviate cancer-related fatigue in NSCLC patients with lung-spleen qi deficiency type after chemotherapy,thereby improving their quality of life.This approach is worthy of clinical promotion.

Objective:To investigate the effect and safety of pancreatic extracorporeal shock wave lithotripsy (P-ESWL) in treating the chronic pancreatitis (CP) patients with main pancreatic duct (MPD) stones and to analyze the influencing factors of success of lithotripsy.Methods:Clinical data of 132 patients with CP complicated with MPD stones treated with P-ESWL in the Department of Gastroenterology, Ruijin Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January 2022 to December 2023 were retrospectively analyzed, including 103 males and 29 females, aged (50.3±16.9) years. The times of P-ESWL, the success rate of stone fragmentation, the necessity of combining endoscopic retrograde cholangiopancreatograhy (ERCP), clearance rate of MPD stones, and incidence of post-P-ESWL complications (acute pancreatitis, abdominal hematoma, infection, steinstrasse, perforation, etc.) were evaluated. The factors influencing the success rate of lithotripsy were analyzed using univariate and multivariate logistic regression.Results:All patients underwent P-ESWL treatment, with (2.23±0.82) times of P-ESWL per person. The success rate of stone fragmentation was 87.1%(115/132). Of 107 CP patients (81.1%, 107/132) were treated with their first P-ESWL. Of 12 patients (9.1%, 12/132) underwent single P-ESWL, and 120 (90.9%, 120/132) underwent P-ESWL combined with ERCP. There were 95 cases (72.0%, 95/132) with effective removal of stones, and 62 (47.0%, 62/132) with complete removal of stones. Post-P-ESWL complications included eight cases (6.1%, 8/132) of acute pancreatitis, two (7.6%, 2/132) of steinstrasse complicated with acute pancreatitis and one (0.8%, 1/132) of abdominal hematoma. No infection or perforation occurred. Multivariate logistic regression analysis showed that the higher CT value of stones ( OR=1.239, 95% CI: 1.040-1.477, P=0.017) was associated with the lower success rate of stone fragmentation. Conclusion:P-ESWL is safe and effective in treating patients with CP complicated with MPD stones. The CT value of stones is a risk factor for the success rate of P-ESWL.
