Objective To explore the efficacy and safety of recombinant human anti-severe acute respiratory syn-drome coronavirus 2(anti-SARS-CoV-2)monoclonal antibody injection(F61 injection)in the treatment of patients with coronavirus disease 2019(COVID-19)combined with renal damage.Methods Patients with COVID-19 and renal damage who visited the PLA General Hospital from January to February 2023 were selected.Subjects were randomly divided into two groups.Control group was treated with conventional anti-COVID-19 therapy,while trial group was treated with conventional anti-COVID-19 therapy combined with F61 injection.A 15-day follow-up was conducted after drug administration.Clinical symptoms,laboratory tests,electrocardiogram,and chest CT of pa-tients were performed to analyze the efficacy and safety of F61 injection.Results Twelve subjects(7 in trial group and 5 in control group)were included in study.Neither group had any clinical progression or death cases.The ave-rage time for negative conversion of nucleic acid of SARS-CoV-2 in control group and trial group were 3.2 days and 1.57 days(P=0.046),respectively.The scores of COVID-19 related target symptom in the trial group on the 3rd and 5th day after medication were both lower than those of the control group(both P＜0.05).According to the clinical staging and World Health Organization 10-point graded disease progression scale,both groups of subjects improved but didn't show statistical differences(P＞0.05).For safety,trial group didn't present any infusion-re-lated adverse event.Subjects in both groups demonstrated varying degrees of elevated blood glucose,elevated urine glucose,elevated urobilinogen,positive urine casts,and cardiac arrhythmia,but the differences were not statistica-lly significant(all P＞0.05).Conclusion F61 injection has initially demonstrated safety and clinical benefit in trea-ting patients with COVID-19 combined with renal damage.As the domestically produced drug,it has good clinical accessibility and may provide more options for clinical practice.

The pedicle screw internal fixation system plays a crucial role in spinal surgery, with the advantage of enhancing spinal stability. However, potential complications such as internal fixation loosening and screw pullout still exist clinically. Currently, pullout of strength is commonly used to evaluate the short-term biomechanical properties of internal fixation, fatigue test is performed to evaluate the long-term biomechanical properties of internal fixation, and torque is used to evaluate the interaction between screws and spinal bone. Factors that influence the biomechanical properties of pedicle screws include spine-related factors (bone density) and screw-related factors (screw size, screw design, and screw augmentation materials). In bones with high bone density, pullout of strength is significantly increased, and fixation strength can also be improved by increasing screw diameter and length, improving screw design, and using screw augmentation materials. Biomechanical research on pedicle screw internal fixation provides key information for achieving individualized and functional optimal channel selection. Designing screw channels with optimal fixation strength is expected to reduce the risk of screw loosening and the occurrence of surgical complications, and improve surgical effects.

Microsporidia is a group of intracellular parasitic eukaryotic microorganisms that pose threats to livestock fish production and human health, but there is no special chemo-therapeutic drug available for the treatment of microsporidia currently. In this study, sulfonamide derivatives of spectinomycin were designed by taking into consideration the low toxicity of spectinomycin and the favorable pharmaceutical properties of sulfonamides. Through the exploration of reaction conditions, a total of 21 target molecules were synthesized with a yield of 52%-74% and their chemical structures were confirmed by ¹H NMR, ¹³C NMR, and high resolution mass spectrometry (HR MS). By screening in vitro, the host cell cytotoxicity and biological activity of target molecules to Encephalitozoon hellem, a representative of vertebrates infecting microsporidia, were studied. It was found that four target molecules each could inhibit or promote the proliferation of E. hellem. In this study, the synthesis method of sulfonamide derivatives of spectinomycin was established, and new compounds effective against E. hellem were discovered, which provided a new idea for the further derivatization of spectinomycin and the development of therapeutic drugs targeting microsporidia.

Metabolic dysfunction-associated steatotic liver disease (MASLD), also called non-alcoholic fatty liver disease, is the most epidemic chronic liver disease worldwide. Metabolic dysfunction-associated steatohepatitis (MASH) is the critical stage of MASLD, and early diagnosis and treatment of MASH are crucial for reducing the incidence of intrahepatic and extrahepatic complications. So far, pharmacotherapeutics for the treatment of MASH are still a major challenge, because of the complexity of the pathogenesis and heterogeneity of MASH. Many agents under investigation have shown impressive therapeutic effects by targeting different key pathways, including the attenuation of steatohepatitis or fibrosis or both. It is notable that thyroid hormone receptor-β agonist, resmetirom has become the first officially approved drug for treating MASH with fibrosis. Other agents such as peroxisome proliferator-activated receptor agonists, glucagon-like peptide-1 analogs, and fibroblast growth factor 21 analogs are awaiting approval. This review focuses on the current status of drug therapy for MASH and summarizes the latest results of new medications that have completed phase 2 or 3 clinical trials, and presents the future directions and difficulties of new drug research for MASH.

Objective To develop a WeChat based hospital-community-family nursing platform for premature infants and evaluate its effect on transitional care for premature infants.Methods A hospital-community-family nursing platform for premature infants using the WeChat applet was developed.A total of 96 preterm infants hospitalised in our hospital between January and September 2021 were enrolled and randomly divided into an observation group and a control group using a random number table,with 48 per group.The premature infants in the observation group were offered with transitional care intervention based on the WeChat based nursing platform developed by us,and those in the control group were on routine outpatient clinic visits and telephone follow-ups.The premature infants of the two groups were compared in terms of physical development,neuropsychological development and re-admission rate within the age of one year.Results A total of 46 premature infants in the observation group and 47 in the control group went through the study.After the intervention,the body length,weight and head circumference of the preterm infants in the observation group were all significantly greater than those in the control group,with F-values between the two groups of 5.338(height),4.133(weight)and 3.069(head circumference)(all P＜0.05).The total development quotient and the development quotient of each energy area in the observation group were significantly higher than those in the control group,with F-values between the two groups at 29.881(large movement),22.007(fine movement),17.722(adaptability),22.467(language),34.058(social)and 14.331(total developmental quotient)(all P＜0.001).The readmission rate of the premature infants in observation group was statistical significant lower than that of the control group(P＜0.05).Conclusions The WeChat based hospital-community-family nursing platform is effective in transitional care for premature infants.It can promote physical development and neuropsychological development of premature infants,and reduce the readmission rate..

Objective To explore the current status of H.pylori infection in the natural population of Sanya City,analyze its influencing factors,and provide a reference basis for the prevention and control of H.pylori infection.Methods A total of 677 residents from four districts of Sanya City were selected by overall stratified random sampling method,and were subjected to urea 14C breath test and questionnaire survey to calculate the positive rate of H.pylori in the natural population and analyze the influencing factors of H.pylori infection.Results A total of 606 residents were included,and the number of H.pylori positive detections was 261,with a positive detection rate of 38.5％.Among them,different ethnicity,marital status,smoking,eating vegetables and fruits,and literacy level were associated with H.pylori infection(P＜0.05);gender,age,BMI,alcohol consumption,drinking water source,betel quid chewing,and the number of cohabitants were not significantly associated with H.pylori infection(P＞0.05).Family infection was an independent risk factor for H.pylori infection in the natural population of Sanya City,and Li ethnicity,frequent consumption of fruits and vegetables,and college and higher education level were independent protective factors for H.pylori infection in the natural population of Sanya City.Conclusion The rate of H.pylori infection in the natural population of Sanya City is lower than the national average.Consuming more fruits and vegetables and improving the awareness of hygiene protection are conducive to the prevention of H.pylori infection;and the promotion of the family and related members with the same examination and treatment is important to avoid aggregation of infection within the family.
