RESUMEN
Objective:Severe trauma events are emergent, with low incidence and unpredictable. Current guideline does not provide precise recommendations on how the trauma centers should arrange the number of beds in trauma intensive care units while making rational use of medical resources. We analyzed the trauma intensive care unit bed requirement in the branch campus of our hospital to propose a reasonable assessment.Methods:Patients with severe trauma sent to the Intensive Care Unit of Peking University People's Hospital from January 2022 to June 2022 were collected. The daily number of patients received intensive care was counted. The bed requirement of the intensive care unit covering 99% of clinical needs was calculated based on the probability distribution function.Results:From January 2022 to June 2022, 103 patients with severe trauma [74 males and 29 females, aged (51.47±16.06) years, ranging 16 to 87 years] were included in the study. Among the 103 patients, 57 were injured in traffic accidents, 26 fell from a high altitude, 12 fell, 4 were hit by heavy objects, and 4 were stabbed. TISS ranged from 16 to 50. The range of the daily bed requirement in the intensive care unit was 0–10, which was consistent with the Poisson distribution. According to the probability distribution function, nine trauma intensive care beds could meet 99.19% of clinical needs.Conclusions:In severe traumatic events, patients need to be transferred to intensive care unit as soon as possible. For our branch campus, nine trauma intensive care beds can cover more than 99% of clinical needs. It follows that, in accordance with the basic requirements of trauma center construction, hospitals with trauma centers need at least 9 beds in intensive care units. However, traumatic events cannot be predicted; thus, the bed requirement needs to be regularly evaluated.

Oxalate calculi were the most common in all age groups, and urate calculi were the most common in the 21 to 40 age group. Calcium oxalate calculi were most common in the ureter (127, 76.5%), significantly higher than in other sites (χ2=3.222, P=0.020). Calcium oxalate + calcium hydrogen phosphate calculi was the least common in the bladder, significantly different from the other parts (χ2=2.092, P=0.037). Magnesium ammonium phosphate hexahydrate and/or calcium carbonate or calcium oxalate calculi were the most common in the kidney (50.0%), significantly different from the other parts (χ2=9.448, P=0.007). 【Conclusion】 In Longnan area, the incidence of urinary calculi is significantly higher in male than in female. Ureteral calculi are mainly composed of calcium oxalate + carbonated apatite and calcium oxalate. According to different risk factors, individual prevention programs should be developed.
RESUMEN
Traditional Chinese medicine (TCM) colleges and universities are important positions for inheriting and innovating the TCM culture. Exploring the innovation of teaching modes of ideological and political courses in TCM colleges and universities is a hot topic in current researches on education and teaching reform. There are some problems in the characteristic construction of ideological and political courses in TCM colleges and universities, such as insufficient effective integration of TCM culture, incomplete integrated design, and lack of supervision and evaluation system. In practical exploration, the "11432" teaching mode of ideological and political course based on the cultural characteristics of TCM has been formed. It is guided by "two major goals" and "three requirements", and organically integrates the TCM culture into the teaching of ideological and political course according to the principle of gradual progress. It takes the "Four Adherences" as its practice practical focus, and strives to create a "student-centered" classroom teaching mode. What’s more, it focuses on promoting the organic integration of TCM culture and ideological and political courses from the "five dimensions" in accordance with the fundamental task of "fostering virtue through education" and the requirements for talent training in TCM colleges and universities.

RESUMEN
Objective:To evaluate the efficacy and safety of apatinib in combination with chemoradiotherapy for head and neck squamous cell carcinoma (HNSCC).Methods:37 patients orally received apatinib at 250 mg/d during concurrent chemoradiotherapy until completion of radiotherapy, complete remission assessed by imaging examination, the onset of unacceptable toxicity or death. Baseline characteristics, objective response rates (ORR) and adverse events were assessed in all enrolled patients with complete baseline and safety data. Progression-free survival (PFS) and overall survival (OS) were calculated by Kaplan-Meier method. Prognostic factors were statistically identified using Cox regression models.Results:The ORR was 85%(95% CI: 72%-98%). The median PFS was 17.9 months and the 2-year OS rate was 62%(95% CI: 48%-80%). Ineffective short-term efficacy ( HR=0.035, 995% CI: 0.02-0.652, P=0.025) was an independent risk factor for poor OS. In addition, ineffective short-term efficacy ( HR=0.104, 95% CI: 0.017-0.633, P=0.014) and lymphocytopenia ( HR=17.539, 95% CI: 2.040-150.779, P=0.009) were independent risk factors for poor PFS. Common adverse events (>60%) included lymphocytopenia (76%), leukopenia (68%) and irradiation-induced mucosal injury (65%). The most common treatment-associated grade 3 adverse event was lymphopenia (49%). Conclusions:Apatinib combined with chemoradiotherapy yield significant anti-tumor activity for HNSCC with controllable toxicity. For patients with advanced HNSCC, short-term efficacy and lymphocytopenia may be potential predictors for clinical efficacy of apatinib combined with chemoradiotherapy.
RESUMEN
Promoting the collaborative education of curriculum ideology and politics and ideological and political courses is a realistic choice to implement the fundamental task of morality education. The methods, to solve the outstanding problems such as the "uncoordinated" between the two curriculum systems of curriculum ideology and politics and ideological and political courses in medical colleges, the "insignificant" effect of collaborative education between professional course teachers and ideological and political course teachers, and the "insufficient" embodiment of the concept of collaborative education in the medical talent training scheme, are related to the quality of talent training in medical colleges and universities. The collaborative education mode of curriculum ideology and politics based on "great medical sincerity" and ideological and political courses have been formed in the practice and exploration. With "great medical sincerity" as the link, with "two supports" and "four focus points" to build a platform mutually integrated two curriculum; with "three platforms" as the support to improve the collaborative education ability of professional teachers and ideological and political teachers; with "five entry strategy" to promote the implementation of the collaborative education concept. This mode has greatly reversed the "insufficient" phenomenon of collaborative education of curriculum ideology and politics and ideological and political courses in medical colleges.

RESUMEN
Digital polymerase chain reaction ( PCR) has been experiencing a rapid development during the past few years. Comparing with the traditional real-time quantitative PCR ( RT-qPCR) , using the same primer and probe, the accuracy for the absolute quantification of target gene is significantly improved. The development of digital PCR is directly related to the development of microfluidics. The integrated fluid circuit is an early combination of the microfluidics and digital PCR, which has a complicated fabrication process with high cost. Recently, researchers are trying to apply the droplet microfluidics in digital PCR, and the droplet microfluidic chip is able to generate millions of droplets within a short time. Each of these droplets containing no more than one target gene is a reaction chamber during the amplification process. After amplification, each droplet is tested to achieve the absolute quantification of the target gene. This paper reviews the recent progresses of droplet digital PCR, and the applications of droplet digital PCR in biological, medical and environmental fields.

RESUMEN
Fumonisin B1 (FB1) is a carcinogenic mycotoxin found in commodities such as corn and corn-originated products. An aptamer-based method for detection of FB1 was developed using the fluorescent dye PicoGreen, which can recognize and bind double-stranded DNA. A peak fluorescence of PicoGreen was obtained in 15 min in the presence of FB1 aptamer, which formed a double-stranded hybridizer DNA with its complementary strand. The excitation and emission wavelengths for PicoGreen detection were 480 nm and 520 nm, respectively. The sensitivity of this aptamer/PicoGreen-based method was 0.1 μg/L. This method showed a good linearity for FB1 concentration ranging from 0.1 to 1 μg/L. The entire detection procedure for FB1 could be completed within 40 min. No cross reactions were observed with any other mycotoxins against aflatoxin B1, ochratoxin A, citrinin and zearalenone, demonstrating high specificity towards FB1 aptamer. Agreement between commercial, antibody-based enzyme-linked immunosorbent assay (ELISA) kit and aptamer method was excellent with a kappa value of 0.857. Taken together, this aptamer/PicoGreen-based method is more cost-effective, time-saving and useful than ELISA for detection of FB1.
