Objective To retrospectively analyze pathogen distribution,antimicrobial resistance,and their chan-ging trends in patients with infectious endophthalmitis admitted to a hospital in Xingtai area during the past 10 years.Methods Patients with infectious endophthalmitis and were detected pathogens admitted to Hebei Eye Hos-pital from January 2014 to December 2023 were selected for a retrospective study.Culture results and antimicrobial resistance of pathogens from patients with endophthalmitis were summarized and analyzed.The mutation character-istics of resistance genes and cassette chromosome recombinase genes in methicillin-resistant Staphylococcus epider-midis(MRSE)strains were explored.In vitro virulence between MRSE strains carrying mutant and non-mutant genes was compared using serum killing test.Results A total of 671 patients(671 eyes)with infectious endoph-thalmitis were included in the study,with 484 pathogenic strains(from 484 eyes)isolated.The average age of pa-tients was(65.66±25.14)years old.There were no statistically significant differences in the constituent rates of pathogens among infectious endophthalmitis patients of different genders and ages(both P＞0.05).Incidence of in-fectious endophthalmitis was higher in summer and lower in winter.Except 2018,there were statistically significant differences in the constituent rate of infectious endophthalmitis among different seasons from 2016 to 2023(all P＜0.05).A total of 176 strains of Staphylococcus epidermidis,81 strains of Streptococcus,and 48 strains of Pseudo-monas aeruginosa were isolated.The resistance rates of Staphylococcus epidermidis to penicillin,erythromycin,and oxacillin were all over 40％,with a resistance rate of 64.20％to penicillin.From 2019 to 2023,the resistance rates of Staphylococcus epidermidis to penicillin,erythromycin,oxacillin,compound sulfamethoxazole,and cipro-floxacin were all higher than those from 2014 to 2018,and the differences were all statistically significant(all P＜0.05).The resistance rates of Streptococcus to azithromycin,erythromycin,and clindamycin were all over 80％.The resistance rate of Pseudomonas aeruginosa to both ciprofloxacin and piperacillin exceeded 70％.Among the 113 MRSE strains,the resistance genes ermA,ermB,and ermC accounted for 12.39％(n=14),13.27％(n=15),and 74.34％(n=84),respectively.The cassette chromosome recombinase genes mainly included ccrA1-ccrB1,ccrA2-ccrB2,and ccrA3-ccrB3 types.Gene mutations were detected from all three types of resistance genes,with a mutation rate of 81.42％(92/113).The colony count of antimicrobial-resistant gene-mutated Staphylococcus epi-dermidis was higher than that of non-mutated strains in serum killing test at 2 and 3 hours(both P＜0.05).Conclusion The constituent rates of pathogens in infectious endophthalmitis remained stable over the 10 years,with the highest proportion in summer and the lowest in winter.The detection rate of antimicrobial-resistant pathogens presented rising tendency,and the resistance gene of MRSE was mainly ermC.Testing and monitoring of MRSE strains should be strengthened in clinic to prevent the cloning and spread of resistance genes.

Barrett's esophagus(BE),a precancerous state of esophageal adenocarcinoma,poses a major challenge for prevention and treatment owing to its complex mechanism of inflammation-cancer transformation and the lack of effective clinical treatment and torsion strategies.Building upon the"preventing disease progression"theory,this study aimed to address the critical clinical challenge of intercepting the pathological progression during the inflammation-cancer transformation of BE by proposing an innovative"two critical nodes-three stages"pathomechanism framework.The pathogenesis of BE originates from liver depression and qi stagnation.The pathological progression evolves through two critical nodes:liver depression transforming into heat and heat transforming into blood stasis,representing a three-stage evolutionary pattern of qi stagnation,heat transformation,and blood stasis formation.Acidic bile salts,acting as a pathogenic toxin,permeate the entire process and catalyze carcinogenesis.Based on this understanding,the therapeutic principles of"treatment from the liver"and"truncation and torsion"were established,emphasizing stage-specific interventions.For the qi stagnation stage,treatment focuses on soothing the liver and regulating qi,as well as moistening,harmonizing,and descending the qi.This is achieved by combining modified Chaihu Shugan Powder with Xuanfu Daizhe Decoction,while using pungent and drying herbs cautiously and supplementing them with light and floral herbs.In the heat transformation stage,the strategy aims to clear the liver and drain heat while protecting yin and harmonizing the stomach,employing modified Huaganjian combined with Yiguanjian and supplemented with Jinlingzi Powder to clear depressed fire.For the blood stasis formation stage,treatment involves activating blood and resolving stasis,combined with supporting healthy qi and removing toxins.This is achieved using a modified Gexia Zhuyu Decoction,supplemented with Liujunzi Decoction,and additions such as Radix Salviae Miltiorrhizae and turtle carapace to disperse nodules and reduce masses.This theoretical framework establishes a diagnostic and therapeutic model characterized by the integration of disease mechanisms with pathology and the mutual reference of macro-level signs with micro-level indicators.It provides a comprehensive clinical practice pathway,complete with principles,methods,formulas,and herbs,for the stage-specific interception of inflammation-cancer transformation in BE using traditional Chinese medicine.

The ethanol ectract of processed product of W. indica has certain anti-inflammatory activity too ，but its hepatorenal toxicity was lower than raw product. The “sweat soaking method ” possesses the function of “retaining efficiency and reducing toxicity ”for processing W. indica .

Objective: To study the feasibility, safety and aesthetics of laparoscopic cholecystectomy using a single-port through the umbilicus in patients with chronic cholecystitis with cholecystolithiasis. Methods: From Jan 2007 to Jun 2017, the clinical data of 4790 patients who underwent single-port, 4 426 patients conventional three-ports, and 3 304 patients two-ports laparoscopic cholecystectomy were retrospectively studied. Results: There were no death in all the three groups. There were no significant differences in the incidences of postoperative bleeding, bile leakage, biliary tract injury and other significant short-term complications (all P>0.05). The operation time of transumbilical single-port laparoscopic cholecystectomy was significantly longer than that of two-ports and three-ports laparoscopic cholecystectomy [(35.3±9.0)min vs. (28.4±7.2)min vs. (23.3±6.4)min, P<0.05]. Looking only in a single year, there was no significant difference in the operation time of the three groups in the year 2017 (P>0.05). There were no significant differences among the three groups in intraoperative blood loss, first postoperative passing of flatus, postoperative pain, and length of hospital stay (all P>0.05). The satisfaction score of surgical scar in the single-port group was higher than that in the two-ports and three-ports groups [(9.6±1.6) vs. (7.6±1.9) vs. (6.7±2.0), P<0.05]. Conclusions Transumbilical single-port laparoscopic cholecystectomy was safe and feasible, with good aesthetics and other advantages. It was more difficult than the traditional laparoscopic technique. After the learning curve, the operation time could be comparable to the three-ports technique.

Objective: To explore the application of septoplasty and cheiloplasty in complete unilateral cleft lip repairment, and evaluate the effect on nasal shape correction. Methods: Twenty-four infants with complete unilateral cleft lip were divided into two groups: the correction group and the control group. Both groups underwent cheiloplasty by Mohler′s technique, septoplasty was performed in the correction group during the primary cheiloplasty. Six-month follow-up was taken to evaluate the nasal shape with the three dimensional images. Independent-samples t Test was performed using SPSS 21.0, to compare the nasal morphology between two groups. Results: All patients healed in the first stage, and were followed for 6 months after operations. There were no complication, including nasal septum perforation, occurred in either group.There were statistically significant differences in nasal parameters between the correction group and controls (P<0.05). The columellar width, nostril width on the affected side, and columella deviation of the correction group were smaller, than those of controls. The nose tip height, columellar height and nostril height on the affected side of the correction group were greater than those of the control group. Conclusions Septoplasty associated with the primary cheiloplasty in complete unilateral cleft lip repairment, shows better results in the elongation of the nasal columella, and the correction of septum deviation, and provides a stable nasal structure.
