ObjectiveTo evaluate the efficacy and safety of Xiaoji Hufei Formula in protecting children with close contact exposure to influenza， and to provide reference and evidence-based support for better clinical prevention and treatment of influenza in children. MethodsA multicenter， prospective， non-randomized， parallel， controlled trial was conducted from October 2021 to May 2022 in five hospitals， including Dongfang Hospital of Beijing University of Chinese Medicine. Confirmed influenza cases and influenza-like illness （ILI） cases were collected， and eligible children with close contact exposure to these cases were recruited in the outpatient clinics. According to whether the enrolled close contacts were willing to take Xiaoji Hufei formula for influenza prevention， they were assigned to the observation group （108 cases） or the control group （108 cases）. Follow-up visits were conducted on days 7 and 14 after enrollment. The primary outcomes were the incidence of ILI and the rate of laboratory-confirmed influenza. Secondary outcomes included traditional Chinese medicine （TCM） symptom score scale for influenza， influenza-related emergency （outpatient） visit rate， influenza hospitalization rate， and time to onset after exposure to influenza cases. ResultsA total of 216 participants were enrolled， with 108 in the observation group and 108 in the control group. Primary outcomes： （1） Incidence of ILI： The incidence was 12.0% （13/108） in the observation group and 23.1% （25/108） in the control group， with the observation group showing a significantly lower incidence （χ²=4.6， P<0.05）. （2） Influenza confirmation rate： 3.7% （4/108） in the observation group and 4.6% （5/108） in the control group， with no statistically significant difference. Secondary outcomes： （1） TCM symptom score scale： after onset， nasal congestion and runny nose scores differed significantly between the two groups （P<0.05）， while other symptoms such as fever， sore throat， and cough showed no significant differences. （2） Influenza-related emergency （outpatient） visit rate： 84.6% （11 cases） in the observation group and 96.0% （24 cases） in the control group， with no significant difference. （3） Time to onset after exposure： The median onset time after exposure to index patients was 7 days in the observation group and 4 days in the control group， with a statistically significant difference （P<0.05）. ConclusionIn previously healthy children exposed to infectious influenza cases under unprotected conditions， Xiaoji Hufei formula prophylaxis significantly reduced the incidence of ILI. Xiaoji Hufei Formula can be recommended as a specific preventive prescription for influenza in children.

OBJECTIVE: To observe the therapeutic effect of electroacupuncture (EA) in improving early enteral nutrition tolerance in patients with acute pancreatitis (AP) under the concept of accelerated rehabilitation, and to explore the related mechanism based on the changes in autonomic nerve characteristics. METHODS: A total of 42 patients with AP were randomized into an observation group (21 cases, 1 case dropped out) and a control group (21 cases, 1 case dropped out). The control group received standard basic treatment for AP. On the basis of the treatment in the control group, EA was applied in the observation group, bilateral Zusanli (ST36), Yixian point (Extra), Tianshu (ST25), Neiguan (PC6) and Zhongwan (CV12) were selected as the main points, and the supplementary points were selected according to syndrome differentiation. Ipsilateral Zusanli (ST36) and Yixian point (Extra) were connected to EA, using discontinuous wave, in frequency of 2 Hz, 30 min a time, once a day for 6 continuous days. The enteral nutrition tolerance score was observed before treatment and after 3 and 5 days of treatment; the visual analogue scale (VAS) score for abdominal pain was observed before treatment and after 3 days of treatment; the time of reaching the feeding goal and hospital stay was recorded; the levels of C-reactive protein (CRP) and amylase were measured before treatment and after 5 days of treatment; the heart rate variability (HRV) indexes (standard deviation of NN intervals [SDNN], average standard deviation of NN intervals [SDANN], root mean square of successive NN interval differences [rMSSD], low frequency [LF] and high frequency [HF], ratio of low frequency to high frequency [LF/HF]) were monitored in the two groups. RESULTS: After 3 and 5 days of treatment, the enteral nutrition tolerance scores were decreased compared with those before treatment in both groups (P<0.01), the reductions in the observation group were larger than those in the control group (P<0.01). After 3 days of treatment, the VAS scores for abdominal pain were decreased compared with those before treatment in both groups (P<0.01), the reduction in the observation group was larger than that in the control group (P<0.01). The time of reaching the feeding goal and hospital stay in the observation group was shorter than that in the control group (P<0.05). After 5 days of treatment, the CRP and amylase levels were decreased compared with those before treatment in both groups (P<0.01), the reduction of CRP level in the observation group was larger than that in the control group (P<0.01). In the observation group, SDNN, SDANN and LF/HF were lower than those in the control group (P<0.05, P<0.01), while rMSSD was higher than that in the control group (P<0.01). SDNN, SDANN and LF/HF were positively correlated with the enteral nutrition tolerance scores after 3 and 5 days of treatment (P<0.05), while rMSSD was negatively correlated with the enteral nutrition tolerance scores after 3 and 5 days of treatment (P<0.01). CONCLUSION Electroacupuncture can improve enteral nutrition tolerance in patients with AP by regulating autonomic nervous function, alleviating the inflammation, promoting accelerated recovery, and reducing the length of hospital stay.

This study aimed to evaluate the efficacy and safety of combining albumin-bound paclitaxel (abpaclitaxel) and anlotinib for ovarian cancer. In this study, 44 patients diagnosed with platinum-resistant ovarian cancer were enrolled. Patients received ab-paclitaxel along with anlotinib until disease progression or intolerable toxicity. Efficacy was assessed according to RECIST 1.1 criteria or Rustin's criteria. The primary endpoint was the investigator-evaluated objective response rate (ORR). 44 patients were enrolled between January 2021 and March 2023 with a median age of 49 years. Twenty-nine had measurable lesions and 15 had non-measurable lesions. Overall, the investigator-evaluated ORR was 56.8% (25/44; 95% CI 0.411-0.713) in intention-to-treat population and 58.1% (25/43; 95% CI 0.422-0.726) in per-protocol population. The median progression-free survival was 9.8 months, and the median duration of response was 7.4 months. For safety, grade 3/4 adverse events (AEs) included leukopenia, gum pain, hypertension, and hand-foot syndrome. The response rates were 55.0% (11/20) in patients with previous use of antiangiogenic reagents and who had previous use of PARP inhibitors. The combination of ab-paclitaxel and anlotinib showed promising anti-tumor activity and a manageable safety profile in platinum-resistant ovarian cancer. Patients with previous use of antiangiogenic drugs or PARP inhibitors still benefited from this protocol.

Objective:To investigate the clinical efficacy of subcutaneous asymmetric tension reduction combined with dermal buried angular mattress suture in surgical treatment of benign pigmented facial lesions in infants and preschoolers.Methods:Totally, 100 infants and preschoolers with pigmented facial lesions were enrolled from the Department of Dermatology, Hanzhong Central Hospital and the Second Affiliated Hospital of Xi′an Jiaotong University from January 2018 to January 2019, and their clinical data were analyzed retrospectively. Among these patients, there were 59 males and 41 females, and their age ranged from 3 months to 5 years, with an average age of 15 months. All patients underwent outpatient surgery under local anesthesia, and sedative drugs were used before operation. The skin lesions were excised once or in stages according to their areas, and incisions were closed by using a subcutaneous asymmetric suture-based tension reduction technique, followed by dermal buried angular mattress sutures. After surgery, medical silicone gels and tension reduction devices were used for 6 months to 1 year, and postoperative follow-up was performed.Results:All patients were followed up for more than 1 year after surgery. Four patients showed suture rejection reaction within two months after surgery, and the incisions completely healed after the suture knots were discharged; cat′s ear-shaped scars were formed at the upper and lower ends of the incisions in 3 cases when the sutures were removed 1 week after surgery, no treatment was given, and the cat′s ear-shaped scars gradually became flat after 1 year of follow-up; fat liquefaction occurred in 1 case 4 days after surgery, re-suturing of the incision was done 1 week after the removal of internal sutures and drainage, and the incision healed well; 1 case developed infection 3 days after surgery, and then received the removal of internal sutures, drainage, and anti-infection treatment, re-suturing was performed after complete regression of the incision swelling, and the incisions healed well; scar hyperplasia occurred in 4 cases 3 to 6 months after surgery, and the scars became flat after the local injection of triamcinolone acetonide. In the remaining children, fine white linear scars were formed after the healing of incisions, the depressions and ridges at both ends of the incisions became flat, and there was no obvious pulling sensation in facial organs or formation of cat′s ear-shaped scars.Conclusions:Subcutaneous asymmetric tension reduction combined with dermal buried angular mattress suture can effectively reduce tension twice during delicate facial surgery in infants and preschoolers, and help to avoid incision widening and scar hyperplasia. The follow-up showed favorable long-term efficacy and aesthetic effect.

ObjectiveTo evaluate the dynamic disinfection effect of the upper-room 222 nm ultraviolet radiation on the air in different areas of the emergency department, and to provide references for a new solution of air disinfection that man-machine coexisted in the medical and healthcare institutions. MethodsThe upper-room 222 nm ultraviolet radiation air sterilizers were installed at a height of 2.3‒2.6 m from the ground in the observation room, computed tomography (CT) scanning room, rescue room and consulting room of the emergency department in Beijing Tiantan Hospital, Capital Medical University . The test area was divided into a 222 nm ultraviolet group and a control group according to whether the 222 nm ultraviolet germicidal air disinfection was conducted or not. The experimental group started air disinfection at8:00 a.m., and the air sampling was conducted from 9:00 a.m. to 16:00 p.m., with a 10 min sampling interval of every 1 hour. While the control group only collected air sample with the same air sampling method used in the experimental group, without air disinfection. The air microbial sampler with six-level sieve impingement was used for the air sampling, and the differences in the total number of airborne bacterial colonies were compared between the two groups. ResultsA total of 128 air samples were collected in the trial, of which 64 were from the experimental group and 64 from the control group. The total number of airborne bacterial colonies in the experimental group was lower than that in the control group (all P<0.001), and was maintained at a lower level throughout the entire period. The killing rate of 222 nm ultraviolet radiation to airborne microorganisms was approximately 55.76% to 76.33% in different sampling areas. The qualified rates of the total number of dynamic airborne bacterial colonies in the observation room, rescue room and consulting room were improved from 12.50%, 37.50% and 25.00% to 81.25%, 100.00% and 100.00%, respectively (all P<0.001). Over 62.50% of the time, the air quality in the consulting room and CT room in the 222 nm ultraviolet group met the environment standards for airborne bacterial colony criteria of class Ⅰ or class Ⅱ. ConclusionThe upper-room222 nm ultraviolet radiation germicidal disinfection can effectively reduce the total number of airborne bacterial colonies and improve the environment for emergency department, and the continuous using of it is helpful for keeping the air safe and clean.

Objective:To explore the impact of pembrolizumab combined with chemotherapy on angiogenesis and circulating endothelial cells in patients with advanced non-small cell lung cancer (NSCLC) .Methods:The retrospective analysis of clinical data from 121 patients diagnosed with advanced NSCLC who were admitted to the Second Affiliated Hospital of Xingtai Medical College from August 2021 to January 2023 was conducted. These patients were divided into a control group ( n=57) and an observation group ( n=64) based on the designated treatment protocol. Specifically, individuals in the control group received standard chemotherapy (cisplatin+paclitaxel), while those in the observation group underwent penpilimab therapy in conjunction with conventional chemotherapy. The comparative assessment encompassed short-term clinical efficacy, quality of life, immune function parameters, angiogenic factors [including endostatin, insulin-like growth factor 1 (IGF-1), and vascular endothelial growth factor (VEGF) ], circulating endothelial cells, and adverse reactions within the two groups. Results:After 6 courses of treatment, the objective response rate [67.19% (43/64) vs. 49.12% (28/57) ] and disease control rate [87.50% (56/64) vs. 70.18% (40/57) ] in observation group were higher than those in control group, with statistically significant differences ( χ2=4.06, P=0.044; χ2=5.52, P=0.019). The quality of life score of observation group [ (56.77±6.81) points] was significantly higher than that of control group [ (47.73±8.23) points], with a statistically significant difference ( t=6.61, P<0.001) ; The T cell subgroup CD3 + levels [ (63.59±9.00) % vs. (53.06±8.80%), t=6.49, P<0.001], CD4 + levels [ (46.54±8.20) % vs. (30.74±7.32) %, t=11.13, P<0.001] and CD4 +/CD8 + ratio (1.90±0.36 vs. 1.21±0.28, t=11.66, P<0.001) in observation group were significantly higher than those in control group, with statistically significant differences; Endostatin in observation group [ (48.99±3.43) μmol/L] was significantly higher than that in control group [ (31.35±3.87) μmol/L], with a statistically significant difference ( t=26.58, P<0.001), IGF-1 [ (102.31±20.35) μg/L vs. (134.98±19.02) μg/L] and VEGF [ (31.70±4.32) pg/ml vs. (58.71±5.99) pg/ml] were significantly lower in observation group than those in control group, with statistically significant differences ( t=18.73, P<0.001; t=28.14, P<0.001). The number of circulating endothelial cells in observation group [ (58.77±10.03) /ml] was significantly lower than that in control group [ (87.01±8.01) /ml], with a statistically significant difference ( t=17.20, P<0.001). During treatment, there were no statistically significant differences in the incidence of gastrointestinal reaction ( χ2=0.01, P=0.908), leukopenia ( χ2=0.64, P=0.424), thrombocytopenia ( χ2=0.28, P=0.597), anemia ( χ2=1.66, P=0.197), nephrotoxicity ( χ2=0.64, P=0.424), skin rash ( χ2=1.33, P=0.249) between the two groups. Conclusion:The combination therapy of pembrolizumab and chemotherapy for the treatment of advanced NSCLC has demonstrated noteworthy effectiveness. This regimen has the potential to enhance patients' immune functionality, ameliorate their overall quality of life, suppress angiogenesis, and exhibits a commendable profile of safety and reliability.

Objective:To analyze the current situation of myopia and its related factors among primary school students in a certain district of Beijing City in 2022, and provide a basis for the risk assessment of myopia among primary school students.Method:In June 2022, a cluster sampling method was used to include 376 third-grade students from a primary school in a certain district of Beijing. A questionnaire survey was conducted to collect basic information about students, including eye usage habits, reading and writing postures, and parents′ myopia conditions. The examination of students′ distant visual acuity and refractive status was performed. A multivariate logistic regression model was used to analyze the related factors of myopia occurrence.Results:The age of 376 primary school students was (8.87±0.417) years old, with 48.40% (182) being male. A total of 196 myopia cases were identified, with a myopia rate of 52.13%. The results of the multivariate logistic regression model analysis showed that students who sometimes read while lying down ( OR=2.003, 95% CI: 1.128-3.555), often read while lying down ( OR=18.853, 95% CI: 4.512-78.778), had outdoor activity time less than 120 minutes per day ( OR=4.937, 95% CI: 2.4464-9.892), were engaged in indoor break activities ( OR=4.995, 95% CI: 2.773-8.996), performed eye exercises less than once per day ( OR=8.710, 95% CI: 4.464-16.995), had a reading distance from the book less than 30 cm ( OR=5.098, 95% CI: 2.410-10.787), occasionally maintained a fist distance from the edge of the desk ( OR=1.918, 95% CI: 1.086-3.385), and had high school desks and tables ( OR=5.325, 95% CI: 1.465-19.359) could have a higher risk of myopia occurrence, compared with those who never read while lying down, had outdoor activity time more than 120 minutes per day, maintained outdoor break activities, performed eye exercises more than once per day, had a reading distance from the book more than 30 cm, always maintained a fist distance from the edge of the desk, and had short school desks and tables. Conclusion:The incidence rate of myopia among primary school students in a certain district of Beijing City. in 2022 is relatively high. The occurrence of myopia is related to insufficient outdoor activity time and poor eye usage habits.
