Objective To investigate the screening results and factors affecting abnormal detection rates among high-risk groups of esophageal cancer and to explore effective intervention measures. Methods We investigated and collected the information on gender, education level, age, marital status, symptoms of reflux esophagitis (heartburn, acid reflux, belching, hiccup, foreign body sensation in the pharynx, and difficulty swallowing), consumption of pickled vegetables, salt use, and esophageal cancer incidence of villagers in a natural village in Wenfeng District, Anyang City, Henan Province. Changes in reflux esophagitis symptoms in the high-incidence area of esophageal cancer before and after 16 years were observed, and the relationship of such changes with esophageal cancer was analyzed. Results In 2008, 711 cases were epidemiologically investigated, including 213 cases with one of the symptoms of reflux esophagitis such as heartburn, acid reflux, belching, hiccups, foreign body sensation in the pharynx, and difficulty swallowing (sorted in accordance with the abovementioned symptoms; if there are multiple symptoms, then the former is taken); 55 cases with at least two related symptoms, among which the most symptom was heartburn in 108 cases (15.1%); followed by acid reflux, belching, etc. In 2024, the same group of people was investigated, and eight people were missing because of relocation. A total of 703 people were successfully investigated, of which 189 cases (26.8%) had one of the symptoms of reflux esophagitis, such as heartburn (sorted in accordance with relevant symptoms, if there are multiple symptoms, then the former will be selected); 167 cases (23.7%) had at least two related symptoms, among which the most symptom was heartburn in 139 cases (19.7%); followed by acid reflux. Over 16 years, among the 703 people investigated, 45 cases had esophageal cancer and they had one or more of the abovementioned symptoms. No significant differences in the reflux esophagitis-like symptoms were found between 2008 and 2024 (P=0.26); no significant differences in the composition of reflux esophagitis-like symptoms were found between 2008 and 2024 (P=0.299). Conclusion The detection rate of reflux esophagitis-related symptoms in the population in a high-risk area of esophageal cancer has not decreased in the past 16 years, and the high-risk factors still exist. Esophageal cancer is closely related to reflux esophagitis, and clinical practice can provide early diagnosis and treatment for high-risk population.

Objective To investigate the relationship between tooth loss and the occurrence of esophageal cancer in a natural village in Wenfeng District, Anyang City, Henan Province. Methods A prospective cohort study was conducted to observe the occurrence of tooth loss and esophageal cancer among the asymptomatic residents of the natural village for 16 years from January 2008 to July 2024. Data were analyzed by chi-square test, binary logistic regression, and restricted cubic spline. Results Among the total population of 711 cases, 136 cases were lost to follow-up and 575 cases were included in the final statistics, including 45 cases with esophageal cancer. Significant statistical difference was found between esophageal cancer patients with and without tooth loss (P<0.05). Logistic regression analysis showed that tooth loss was associated with the occurrence of esophageal cancer (OR=3.977, 95%CI: 1.543-10.255). After the adjustment for confounders, tooth loss remained significantly associated with the occurrence of esophageal cancer (OR=3.038, 95%CI: 1.035-8.914). A nonlinear dose-response relationship was observed between the number of teeth lost and the incidence of esophageal cancer. When the number of teeth lost was less than 12, the risk of esophageal cancer increased with the number of teeth lost. When more than 12 teeth were lost, the risk of esophageal cancer decreased as the number of teeth lost increased. Conclusion Tooth loss is a risk factor for the occurrence of esophageal cancer in this natural village. When the number of teeth lost is less than 12, the risk of esophageal cancer increases with the number of teeth lost.

OBJECTIVE: To compare the clinical efficacy between microscopic varicocelectomy and laparoscopic varicocelectomy in the treatment of varicocele（VC）with male infertility. METHODS: A total of 307 patients who were diagnosed with VC complicated with male infertility and admitted to the Affiliated Hospital of Qingdao University from October 2018 to October 2022 were recruited for retrospective analysis. The patients were divided into the microscopic group (180 cases) and laparoscopic group (127 cases) according to the surgery method. The pre- and postoperative clinical data of these two groups were analyzed, including the degree of dilatation and reflux time of internal spermatic vein，hemodynamic parameters of testicular capsular artery，proportion of progressive motility spermatozoa (PR), concentration of spermatozoa, proportion of normal morphology sperm，the pregnancy outcome of spouses and the incidence of complications related with surgery within 2 years postoperatively. RESULTS: All the surgeries for the 307 patients in this study were successful. There was no significant difference in operation time, hospitalization time and management expenses between the microscopic group and the laparoscopic group (P>0.05). Compared to the patients in laparoscopic group, the patients in the microscopic group received a better improvement in venous diameter, reflux time of spermatic veins and hemodynamic parameters of testicular capsular artery (P<0.05). Moreover, the semen analysis showed that the PR, spermatozoa concentration and proportion of normal morphology sperm in the microscopic group were also obviously increased than those in the laparoscopic group (P<0.05). During the 2-year follow-up period, the conception rate of spouses in the microscopic group was 67.2%, while only 47.2% in the laparoscopic group, in which the difference was statistically significant (P<0.05). Besides, the time-to-pregnancy ( TTP ) within 2 years postoperatively in the microscopic group was significantly shorter than that in the laparoscopic group（P<0.05). Meanwhile, the incidence of adverse pregnancy outcomes in the microscopic group was also significantly lower than that in the laparoscopic group (P<0.05). It is worth mentioned that the spontaneous conception rate of spouses with successful pregnancy in the microscopic group was also significantly higher than that in the laparoscopic group (P<0.05). Severe complication such as testicular atrophy, bleeding and infection did not appear in both of two groups. However, the incidences of testicular hydrocele and recurrence of VC postoperatively in the laparoscopic group were significantly higher than those in the microscopic group (P<0.05). CONCLUSION Both microscopic varicocelectomy and laparoscopic varicocelectomy can be applied to the management of VC combined with male infertility. But microscopic varicocelectomy showed better clinical efficacy in improving the testicular hemodynamic parameters, semen quality, pregnancy outcome and postoperative complications, which is worthy of further clinical applications.

Objective To analyze the pathogenic bacteria and drug resistance of peritoneal dialysis-associated peritonitis(PDAP),and provide a clinical reference for the rational use of antibiotics.Methods The demographic data of PDAP patients admitted to the peritoneal dialysis(PD)Center of the First Affiliated Hospital of Soochow University from July 1,2015 to December 30,2021 were collected,and the pathogens,drug resistance and prognosis were retrospectively analyzed.Results A total of 150 episodes of PDAP occurred in 92 patients.The positive rate of PD fluid culture was 61.33％,including 65 cases(70.65％)of Gram-positive(G+)bacteria,mainly Staphylococcus and Streptococcus.Gram-negative(G-)bacteria were in 16 cases(17.39％),mainly Escherichia coli and Enterobacter cloacae.There were 11 cases(11.96％)of multiple infections,including 5 cases of combined fungal infection.From 2016 to 2021,the incidence of G+bacteria-related PDAP decreased from 14 to 8 cases.G+strains were resistant to methicillin(35.00％),and were sensitive to linezolid(100.00％),teicoplanin(100.00％)and rifampicin(100.00％).The sensitivity rate to vancomycin was 98.59％.G-strains were sensitive to ceftazidime(86.36％),ceftizoxime(88.89％)and amikacin(100.00％).The MIC of vancomycin against Staphylococcus showed an upward trend in 2019-2021.The overall cure rate of PDAP was 81.33％in patients who responded to antibiotic treatment,and the cure rate of G+bacteria was higher than that of multiple infections(89.23％vs.36.36％,P＜0.01).The outcome of patients with multiple infections,especially those with concurrent fungal infection was poor.Conclusion The incidence of PDAP in the PD center has shown a decreasing trend in recent years.G+bacteria are still the main pathogenic bacteria causing PDAP,and they are highly resistant to methicillin,so vancomycin should be used as empirical therapy.For G-bacteria,cefotaxime and amikacin can be chosen as empirical therapy.There is a drift in the MIC values of vancomycin against Staphylococcus in the study period,so it is necessary to monitor the MIC of vancomycin against Staphylococcus and its changing trend.

The COVID-19 epidemic has spread to the whole world for three years and has had a serious impact on human life, health and economic activities. China's epidemic prevention and control has gone through the following stages: emergency unconventional stage, emergency normalization stage, and the transitional stage from the emergency normalization to the "Category B infectious disease treated as Category B" normalization, and achieved a major and decisive victory. The designated hospitals for prevention and control of COVID-19 epidemic in Tianjin has successfully completed its tasks in all stages of epidemic prevention and control, and has accumulated valuable experience. This article summarizes the experience of constructing a hospital infection prevention and control system during the "Category B infectious disease treated as Category A" period in designated hospital. The experience is summarized as the "Cluster" hospital infection prevention and control system, namely "three rings" outside, middle and inside, "three districts" of green, orange and red, "three things" before, during and after the event, "two-day pre-purification" and "two-director system", and "one zone" management. In emergency situations, we adopt a simplified version of the cluster hospital infection prevention and control system. In emergency situations, a simplified version of the "Cluster" hospital infection prevention and control system can be adopted. This system has the following characteristics: firstly, the system emphasizes the characteristics of "cluster" and the overall management of key measures to avoid any shortcomings. The second, it emphasizes the transformation of infection control concepts to maximize the safety of medical services through infection control. The third, it emphasizes the optimization of the process. The prevention and control measures should be comprehensive and focused, while also preventing excessive use. The measures emphasize the use of the least resources to achieve the best infection control effect. The fourth, it emphasizes the quality control work of infection control, pays attention to the importance of the process, and advocates the concept of "system slimming, process fattening". Fifthly, it emphasizes that the future development depends on artificial intelligence, in order to improve the quality and efficiency of prevention and control to the greatest extent. Sixth, hospitals need to strengthen continuous training and retraining. We utilize diverse training methods, including artificial intelligence, to ensure that infection control policies and procedures are simple. We have established an evaluation and feedback mechanism to ensure that medical personnel are in an emergency state at all times.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

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.

Objective:To investigate the mechanism of benzyl isothiocyanate(BITC) in the treatment of anaplastic thyroid cancer(ATC).Methods:Using network pharmacological analysis, key targets of BITC and ATC were screened, followed by GO and KEGG enrichment analysis. In order to validate the findings, AutoDock software was used to dock BITC and ATC key targets. BITC was applied to two ATC cell lines(8505C and CAL-62). Flow cytometry was used to analyze cell apoptosis. Autophagy inhibitors hydroxychloroquine sulfate(HCQ) and 3-methyladenine(3MA) were used in combination with BITC. Real-time quantitative PCR was conducted to detect the gene level of LC3B, while Western blotting was utilized to examine the expression of NF-κB, LC3B Ⅱ, Beclin-1, and Bcl-2. In animal experiments, a mouse tumor model was constructed using CAL-62 cells, treated with intraperitoneal injections of BITC(100 mg/kg) and normal saline respectively, administered every other day for a total of 21 days. Immunoblotting of tumor tissue was performed to detect the expression of LC3B Ⅱ, Bcl-2, Beclin-1, and NF-κB.Results:A total of 10 key targets with binding energies≤-4.0 kcal/mol were identified. KEGG analysis showed that these genes are mainly involved in NF-κB signaling pathway and apoptosis. BITC inhibited ATC cells with IC50 values of 27.56 μmol/L for 8505C and 28.30 μmol/L for CAL-62. The expression levels of NF-κB, Beclin-1, and Bcl-2 decreased, while LC3B Ⅱ and LC3B gene expression increased. Combining 3MA with BITC enhanced cell inhibition LC3B Ⅱ expression. HCQ increased LC3B Ⅱ expression without enhancing cell and viability inhibition. In the mouse tumor model, compared to the control group, the treatment group had higher LC3B Ⅱ and lower Bcl-2, Beclin-1, and NF-κB levels.Conclusion:BITC could inhibit the growth of ATC cells in vitro and in vivo, disrupt the autophagy degradation, and inhibit the NF-κB pathway.

As a key epigenetic regulator, histone deacetylases (HDACs) play a crucial role in cancer development. Small molecule HDAC inhibitors have been shown to inhibit tumor proliferation and induce apoptosis, attracting significant research attention. In this study, we designed and synthesized a series of novel saccharin derivatives as HDAC inhibitors. Biological experiments demonstrated that the target compound 9a exhibited superior HDACs inhibition activity to vorinostat and demonstrating promising in vitro and in vivo anti-tumor activity against triple-negative breast cancer (TNBC). All animal experiments in this study were performed in strict accordance with the protocols approved by the Ethical Committee of School of Pharmaceutical Sciences in Shandong University (Approval No. 230094). This work represents an initial exploration of developing saccharin-based HDAC inhibitors, and the active compound 9a could serve as a lead compound for further study.
