Cervical cancer is one of the most common gynecological malignant tumors,the five-year survival rate decreased significantly in the case of lymph node metastasis and distant metasta-sis,so the development of new anti-cervical cancer drugs is of great significance for the treatment of cervical cancer.Molecular docking technology is one of the most commonly used research methods in computer aided drug design,which is widely used in screening the effective components of drugs,finding the targets of drugs acting on tumors and exploring the mechanism of antineoplastic drugs.This paper reviews the molecular docking technology in the screening of anti-cervical cancer drugs,the determination of anti-tumor targets and the mechanism of anti-cervical cancer,in order to provide more sufficient theoretical basis for the screening of anti-cervical cancer drugs and new drug research and development.

This study was aimed at analyzing the Salmonella infection rate,serotype distribution,and drug resistance rate among children with foodborne diseases in Wuhan,to provide evidence for the prevention and control of foodborne diseases in children.We collected pediatric cases of foodborne diseases and fecal specimens in Wuhan from 2017 to 2022,and conducted statistical analysis in SPSS 22.0.A total of 1 180 cases of foodborne diseases in children were monitored,and 281 strains of Salmonella were detected.Salmonella was distributed across 27 serotypes,primarily Salmonella enteritidis(138 strains,ac-counting for 49.11％)and Salmonella typhimurium(37 strains,accounting for 13.17％).The Salmonella-positive cases in-cluded more boys than girls(1.58∶1 ratio),and the age group with the highest detection rate was 7-18 years(34.48％).The proportion of positive patients gradually decreased,and the detection rate gradually increased,with increasing age.Milk and dairy products,fruits and fruit products,and grain and grain products were the main suspected food exposures with high Sal-monella detection rates.The Salmonella detection rate was highest in the third quarter(44.64％),and significant differences were observed in the positivity rates of Salmonella samples across seasons(x2=178.483,P＜0.05).The main clinical mani-festations of children with Salmonella infection were fever(87.19％)and diarrhea(96.44％),primarily watery stool(51.96％).Salmonella showed different degrees of resistance to 14 antibiotics(1.08％-75.99％),primarily ampicillin(75.99％),tetracycline(68.10％),and cefazolin(50.18％).A significant seasonal pattern was observed in the detection of Sal-monella in foodborne diseases among children in Wuhan,and in various suspected food exposures.The serotype composition was polymorphic,and the Salmonella resistance rate was relatively high.Therefore,active monitoring of foodborne diseases and Salmonella resistance surveillance must continue to be strengthened.

Objective:To analyze the mobile of pediatric discharged patients in Beijing from 2013 to 2022 and provide data support for rational planning of pediatric medical resource allocation.Methods:The number,source and flow of pediatric discharges from secondary and higher-level medical institutions in Beijing were described and compared and analyzed visually.Two indicators,the cross-district consultation rate,and the load share ratio,were measured to reflect the outflow rate of patients from the outflow areas and the pressure on the supply of healthcare services in the inflow areas.Results:The proportion of pediatric discharged patients from secondary and upper medical institutions in Beijing was 53.34%.Hebei,Shandong,Henan,Inner Mongolia Autonomous Region,and Shanxi were the main source provinces,with a cumulative proportion of 68.02%.Pediatric patients from other provinces mainly flowed to Xicheng District,tertiary hospitals,and children's hospitals,which was consistent with the main flow of patients in Beijing.There was an interactive flow of pediatric patients between the 16 administrative districts.Between 2020 and 2022,the average annual cross-regional consultation rate of pediatric patients in Fangshan District,Daxing District,Huairou District,Pinggu District,Miyun District,and Yanqing District all had relatively large increases.After considering patients from outlying provinces,the load share of each administrative district increased to varying degrees,with Xicheng District showing a high multiplier increase.Conclusions:The mobility of pediatric patients from other provinces and cross-regional visits in Beijing was relatively high,and both had high targeting and concentration in their choice of visits.It is recommended that a targeted work plan for the relocation of medical functions be formulated,and paediatric patients should be reasonably triaged according to their population and needs,so as to guide a reasonable flow of paediatric patients to seek medical treatment.

Objective:To explore the effectiveness of body weight support in gait training after surgery for an ankle fracture.Methods:Thirty-eight ankle fracture patients who received surgery were divided at random into an observation group and a control group, each of 19. In addition to 3 sessions of routine gait rehabilitation training a week for 6 weeks, only those in the observation group received body weight support training with body weight support boots. Gait data were collected using the GaitWatch three-dimensional gait action capture and training system before the training and after 2, 4 and 6 weeks of the training.Results:At each assessment the gait frequency, gait cycle, stride length, stride rate, bilateral step length, step length deviation, bilateral support phase and bilateral swing phase of both groups had improved significantly. After 6 weeks the average stride frequency, gait cycle, stride length on both sides and speed of the observation group had improved significantly more than among the control group. Step length deviation was not significantly different, however. At each evaluation the proportions of affected and healthy side support had decreased significantly in both groups, but affected and healthy side swing had increased and the proportion of bilateral support had decreased significantly.Conclusion:Body weight support training with body weight support boots can significantly improve gait after ankle fracture surgery. Its effect is superior to that of conventional gait training.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

In the case of extremely shortage of donor kidney sources, the number of Expanded Criteria Donors (ECD) with relatively poor kidney quality and transplantation effect is increasing. In order to alleviate the contradiction between supply and demand by using transplantable kidneys as much as possible and avoid the failure or poor effect of transplantation caused by poor quality kidneys, the quality assessment and evaluation criteria of ECD kidney have become a research hotspot in the field of kidney transplantation. This paper analyzed the possible ethical defects in the research process, and put forward some suggestions for the transplantation team to strictly follow the ethical principles of "no harm", "beneficial" and "informed consent", and the organ transplantation ethics committee to pay attention to the ethical review of the quality evaluation process of ECD donor kidney.

Toxic Chinese materia medica has been highly valued by its specialized and effective effects， but its safe application has become an urgent clinical problem to be solved. Compatibility for toxic attenuation is an important method for the rational clinical application of toxic Chinese materia medica as well as the promotion of its therapeutic advantages. The theory of “heterogeneous medicinals mutual restriction” elaborated in this article has been formed through long-term clinical practice and cognition， and refinement of clinical experience， which means that the nature partiality of toxic Chinese materia medica can be adjusted， and the toxicity can be suppressed through reasonable combination with herbal medicinalsof different properties， flavors， and effects. This theory covers the modes of compatibility for toxicity attenuation and the interaction relationships， like the restriction of medicinals with different properties and flavors， restriction of medicinals with different effects， and inhibiting toxins by reinforcing healthy qi. The opposite and complementary effects of various medicinals combinations are an extension of the connotations of this theory， and the principles can be explained from material basis and mechanism of action. Under the guidance of this theory， it is possible to optimize the compound prescription strategies of toxic Chinese materia medica， and provide new strategies for the clinical combinations of toxic Chinese materia medica， thereby achieving the reduction of toxicity and enhancement of effectiveness of the compound formulas.
