Acquired paralytic strabismus is a common neuromuscular disorder in adults,characterized by diplopia, visual confusion, impaired ocular motility, and ocular deviation, which severely affects the patient's quality of life and overall health. The disease has a complex etiology, encompassing multiple pathological mechanisms such as vascular pathologies, trauma, inflammation, neoplasms, and immune-related disorders. Treatment primarily focuses on addressing the underlying cause. While conventional Western approaches, such as medication and surgery, can alleviate symptoms, some carry the risk of adverse effects, and their long-term recurrence rates warrant careful consideration. Traditional Chinese medicine utilizes distinctive therapies such as herbal medicine, acupuncture, and other adjunctive therapies, which have shown promising therapeutic effects but are constrained by a lack of high-quality evidence from large-scale randomized controlled trials. This review systematically summarizes recent advances in the etiological classification and traditional Chinese and Western medical treatments of acquired paralytic strabismus. It innovatively summarizes the clinical features associated with different causes, analyzes current therapeutic strategies and research landscape, aiming to inform clinical practice and suggest future research directions.

Objective: To analyze characteristics of hepatitis B infection in HBsAg-/HBV DNA+ blood donors in Taiyuan, so as to provide evidence for adjusting blood screening strategies. Methods: Blood samples of HBsAg-/HBV DNA+ donors were tested using enzyme-linked immunosorbent assay (ELISA), chemiluminescence assay, nucleic acid qualitative test, and nucleic acid quantitative test. Data on HBsAg-/HBV DNA+ donors in Taiyuan region from January 1, 2016 to December 31, 2024 were statistically analyzed to evaluate the detection rate, demographic characteristics, influencing factors of detection rate, nucleic acid quantitative results, and serological patterns of HBsAg-/HBV DNA+ donors. Results: From January 1, 2016 to December 31, 2024, 991 565 donor samples underwent nucleic acid testing in Taiyuan. A total of 309 HBsAg-/HBV DNA+ samples were detected, resulting in an HBsAg-/HBV DNA+ detection rate of 3.12 per 10 000. The detection rate varied significantly across different years (P<0.05). Males had a significantly higher HBsAg-/HBV DNA+ detection rate than females, first-time donors had a higher rate than repeat donors, and whole blood donors had a higher rate than apheresis donors (P<0.05). The detection rate also differed significantly among age groups (P<0.05). Logistic regression analysis showed that gender, age, donation frequency, and donation type were all influencing factors for HBsAg-/HBV DNA+ detection (all P<0.05). The predominant serological patterns among HBsAg-/HBV DNA+ donors were HBsAb+/HBcAb+ (43.69%, 135/309) or HBcAb+ alone (24.27%, 75/309). Viral load was detectable in 53.40% (165/309) of the HBsAg-/HBV DNA+ donors. Among these, 61.21% (101/165) donors had a viral load<20 IU/mL, and 94.55% (156/165) had a viral load<200 IU/mL. Donors with viral load<200 IU/mL primarily exhibited HBsAb+/HBcAb+ (41.67%, 65/156) or HBcAb+alone (36.54%, 57/156) serological patterns. Conclusion: The prevalence of HBsAg-/HBV DNA+ is low among blood donors in Taiyuan. Higher detection rates were observed in the 46-55 years age group, males, first-time donors, and whole blood donors. HBsAg-/HBV DNA+ donors exhibit specific serological patterns and generally have low viral loads, indicating a potential residual transfusion risk. It is recommended to add HBcAb testing, together with high-sensitivity nucleic acid testing technologies and donor follow-up, to ensure blood safety and guide donor reentry.

OBJECTIVE: To observe the effect of the direct stimulation of acupuncture at extraocular muscle attachment point on acquired extraocular muscle palsy. METHODS: Thirteen patients with acquired extraocular muscle palsy were treated with acupuncture directly at extraocular muscle (paralytic muscle) attachment point. Firstly, the intraocular conjunctival sac drops of topical anesthetic (procaine hydrochloride eye drops) were administered, 0.2 mL each time, once every 10 minutes, for a total of 3 times. Acupuncture was delivered immediately after the third drop. The sterile acupuncture needle for single use, 0.25 mm×25 mm, was inserted at the anatomical location of the corneal limbal attachment of paralytic extraocular muscle, with an angle of 10° to 15° formed between the needle tip and extraocular muscle, and a depth of 0.3 mm to 0.5 mm. Pivoted by the needle tip, the eyeball was moved passively towards the direction of normal action of orbital muscle, 30 to 50 times until the patient felt soreness of the eyeball; afterwards, the needle was removed. After acupuncture, levofloxacin eye drops were administered once (0.2 mL) at the affected eye. The treatment was given twice a week, and completed when diplopia disappeared. Before and after treatment, the diplopia and the synoptophore circumference were observed respectively. RESULTS: After 7 to 24 (15.46±5.56) times of direct stimulation with acupuncture at extraocular muscle attachment point, the symptoms of diplopia disappeared in 13 patients, the eye position restored to orthophoria, and the circumference of synoptophore was reduced to be (4.04±0.82)° from (19.38±3.98)° detected before treatment (P<0.05). CONCLUSION Acupuncture directly at extraocular muscle attachment can attenuate diplopia and improve ocular muscle function in patients with acquired extraocular muscle palsy.

OBJECTIVE To investigate the serotypes and antimicrobial resistance rate of clinically isolated Salmonel-la in a children's hospital in Suzhou,and to provide reference for the treatment of salmonellosis.METHOD Totally 177 strains of Salmonella isolated from Children's Hospital of Wujiang District from Jan.2021 to Dec.2023 were collected,and the results of serotypes and drug sensitivity of Salmonella were analyzed.RESULTS The male to fe-male isolation rate of Salmonella was 1.39∶1,with a median age of children infection at 1.3(0.8,2.3)years.The highest number of Salmonella strains were isolated in the month of Jun.,followed by Jul.,Aug.,Sep.,Oct.and May,collectively accounting for 82.49％of all isolates.Acute gastroenteritis was manifested in 142 cases(80.22％),with respiratory tract infections in 38 cases(21.47％)and septicemia in 7 cases(3.95％).The differ-ence in detection rates across the three years was not statistically significant(P=0.806).Salmonella Typhimuri-um was the predominant serotype,representing 54.24％of all isolates.The antimicrobial drug with the highest rate of resistance in Salmonella was ampicillin(71.35％,122/171),followed by sulfamethoxazole/metronidazole(43.60％,75/172),and ampicillin/sulbactam(30.23％,52/172),and no imipenem resistant strains were found.29.07％(50/172)of strains showed multidrug resistance.CONCLUSIONS Boys under three years of age are sus-ceptible to Salmonella infections in summer and fall in this region,with Salmonella Typhimurium being the pre-dominant serotype.Clinical attention should be paid to the characteristics of Salmonella infection and drug resist-ance,as well as the early diagnosis and rational use of antimicrobial drugs.

Objective To investigate the distribution and antimicrobial resistance profiles of common pathogens isolated from cerebrospinal fluid(CSF)in CHINET program from 2015 to 2021.Methods The bacterial strains isolated from CSF were identified in accordance with clinical microbiology practice standards.Antimicrobial susceptibility test was conducted using Kirby-Bauer method and automated systems per the unified CHINET protocol.Results A total of 14 014 bacterial strains were isolated from CSF samples from 2015 to 2021,including the strains isolated from inpatients(95.3％)and from outpatient and emergency care patients(4.7％).Overall,19.6％of the isolates were from children and 80.4％were from adults.Gram-positive and Gram-negative bacteria accounted for 68.0％and 32.0％,respectively.Coagulase negative Staphylococcus accounted for 73.0％of the total Gram-positive bacterial isolates.The prevalence of MRSA was 38.2％in children and 45.6％in adults.The prevalence of MRCNS was 67.6％in adults and 69.5％in children.A small number of vancomycin-resistant Enterococcus faecium(2.2％)and linezolid-resistant Enterococcus faecalis(3.1％)were isolated from adult patients.The resistance rates of Escherichia coli and Klebsiella pneumoniae to ceftriaxone were 52.2％and 76.4％in children,70.5％and 63.5％in adults.The prevalence of carbapenem-resistant E.coli and K.pneumoniae(CRKP)was 1.3％and 47.7％in children,6.4％and 47.9％in adults.The prevalence of carbapenem-resistant Acinetobacter baumannii(CRAB)and Pseudomonas aeruginosa(CRPA)was 74.0％and 37.1％in children,81.7％and 39.9％in adults.Conclusions The data derived from antimicrobial resistance surveillance are crucial for clinicians to make evidence-based decisions regarding antibiotic therapy.Attention should be paid to the Gram-negative bacteria,especially CRKP and CRAB in central nervous system(CNS)infections.Ongoing antimicrobial resistance surveillance is helpful for optimizing antibiotic use in CNS infections.

Objective To investigate the antimicrobial resistance of clinical isolates from elderly patients(≥65 years)in major medical institutions across China.Methods Bacterial strains were isolated from elderly patients in 52 hospitals participating in the CHINET Antimicrobial Resistance Surveillance Program during the period from 2015 to 2021.Antimicrobial susceptibility test was carried out by disk diffusion method and automated systems according to the same CHINET protocol.The data were interpreted in accordance with the breakpoints recommended by the Clinical and Laboratory Standards Institute(CLSI)in 2021.Results A total of 514 715 nonduplicate clinical isolates were collected from elderly patients in 52 hospitals from January 1,2015 to December 31,2021.The number of isolates accounted for 34.3％of the total number of clinical isolates from all patients.Overall,21.8％of the 514 715 strains were gram-positive bacteria,and 78.2％were gram-negative bacteria.Majority(90.9％)of the strains were isolated from inpatients.About 42.9％of the strains were isolated from respiratory specimens,and 22.9％were isolated from urine.More than half(60.7％)of the strains were isolated from male patients,and 39.3％isolated from females.About 51.1％of the strains were isolated from patients aged 65-＜75 years.The prevalence of methicillin-resistant strains(MRSA)was 38.8％in 32 190 strains of Staphylococcus aureus.No vancomycin-or linezolid-resistant strains were found.The resistance rate of E.faecalis to most antibiotics was significantly lower than that of Enterococcus faecium,but a few vancomycin-resistant strains(0.2％,1.5％)and linezolid-resistant strains(3.4％,0.3％)were found in E.faecalis and E.faecium.The prevalence of penicillin-susceptible S.pneumoniae(PSSP),penicillin-intermediate S.pneumoniae(PISP),and penicillin-resistant S.pneumoniae(PRSP)was 94.3％,4.0％,and 1.7％in nonmeningitis S.pneumoniae isolates.The resistance rates of Klebsiella spp.(Klebsiella pneumoniae 93.2％)to imipenem and meropenem were 20.9％and 22.3％,respectively.Other Enterobacterales species were highly sensitive to carbapenem antibiotics.Only 1.7％-7.8％of other Enterobacterales strains were resistant to carbapenems.The resistance rates of Acinetobacter spp.(Acinetobacter baumannii 90.6％)to imipenem and meropenem were 68.4％and 70.6％respectively,while 28.5％and 24.3％of P.aeruginosa strains were resistant to imipenem and meropenem,respectively.Conclusions The number of clinical isolates from elderly patients is increasing year by year,especially in the 65-＜75 age group.Respiratory tract isolates were more prevalent in male elderly patients,and urinary tract isolates were more prevalent in female elderly patients.Klebsiella isolates were increasingly resistant to multiple antimicrobial agents,especially carbapenems.Antimicrobial resistance surveillance is helpful for accurate empirical antimicrobial therapy in elderly patients.

Objective To compare the efficacy of testicular repositioning and fixation combined with decompression of the testicular fascial compartment (testicular leucotomy+sheath flap repair) versus conventional testicular repositioning and fixation in surgery for testicular torsion in children. Methods Fifty-six patients with testicular torsion admitted to Hebei Provincial Children's Hospital from January 2019 to October 2023 were selected and divided into the observation group (26 cases) and the control group (30 cases),and the observation group was treated with testicular reorientation and fixation+testicular fascial compartment decompression,while the control group was treated with conventional testicular reorientation and fixation. There was no statistically significant difference in the age and left and right sides of the patients in the two groups (P>0.05). The intraop-erative bleeding,postoperative testicular atrophy,the presence of postoperative scrotal infection and postoperative hospitalization time of the two groups were compared. Results All patients successfully completed the operation without intraoperative complications. There was no statistically significant difference between the observation group and the control group in terms of intraoperative bleeding,postoperative scrotal infection rate and postoperative hospitalization time (P>0.05);the postoperative testicular atrophy rate of the observation group was significantly lower than that of the control group (P<0.05). Conclusions Testicular restoration and fixation+testicular fascial compartment decompression can effectively reduce the pressure of testicular fascial compartment,reduce the ischemia-reperfusion injury of testis,and reduce the occurrence of testicular atrophy,which is safe and effective in the treatment of testicular torsion in children.

Objective To analyze the anatomical relationship between maxillary premolars and the alveolar bone and maxillary sinus using cone-beam computed tomography(CBCT),in order to provide an anatomical basis for immediate implant placement in maxillary premolars.Methods Data from 351 patients who underwent maxillary CBCT imaging at Yancheng Stomatological Hospital between January 2022 and December 2023 were collected.Measurements included the vertical distance between premolar roots and the maxillary sinus floor,intraosseous root length,angle between the tooth axis and alveolar bone axis,and buccal/palatal bone wall thickness,with comparisons of gender differences.Results The median vertical distance between single-rooted maxillary first premolars and the maxil-lary sinus floor was 10.16 mm,while that for second premolars was 4.61 mm.For double-rooted first premolars,the buccal root dis-tance was(4.13±3.99)mm and the palatal root was(5.14±3.94)mm.Maxillary first premolars were farther from the maxillary sinus floor than maxillary second premolars,with palatal roots farther than buccal roots.The intraosseous root length of maxillary first premo-lars was(9.20±1.44)mum,and maxillary second premolars(9.64±2.04)mm.Maxillary first premolars exhibited significantly shorter intraosseous root length than maxillary second premolars.The angle α between tooth axis and alveolar bone axis was 18.89°±6.33° for maxillary first premolars,and 12.65°±6.10° for maxillary second premolars,showing statistically significant differences.The buccal bone wall thickness of maxillary first premolars gradually decreased from 2 mm subcrest to the apex,while palatal bone walls of maxil-lary first premolars and both buccal/palatal walls of maxillary second premolars progressively thickened from 2 mm subcrest to the apex.Significant correlations were identified between angle α and buccopalatal bone wall thickness at mid-root and the apex:increased α cor-responded with reduced buccal wall thickness and enhanced palatal wall thickness.Conclusion The apical region of maxillary first premolars provides sufficient bone volume for primary stability in immediate implantation,though the thin buccal bone wall necessitates careful consideration of implant shape and positioning.Maxillary second premolar roots are closely adjacent to the maxillary sinus floor,requiring implant stabilization with the sinus floor cortical bone or me-siodistal walls of the extraction socket.

Objective:To analyze the influencing factors of postoperative intestinal adhesion in patients undergoing laparoscopic cholecystectomy(LC),and to construct a nomogram prediction model based on this.Methods:A total of 265 patients who underwent LC in our hospital from November 2021 to March 2025 were retrospectively selected and randomly divided into a training set(185 cases)and a validation set(80 cases)according to the ratio of 7∶3.According to the presence or absence of postoperative intestinal adhesion,185 patients in the training set were divided into occur-rence group(28 cases)and non-occurrence group(157 cases).In the validation set,13 cases occurred and 67 cases did not occur.The clinical data of patients were collected to analyze the influencing factors of postoperative intestinal adhe-sion,and a nomogram model was constructed based on this.The receiver operating characteristic(ROC)curve was used to analyze the predictive efficacy of the prediction model on the risk of postoperative intestinal adhesion.Decision curve analysis(DCA)was used to analyze the clinical benefit of the prediction model.Result:The proportion of patients aged≥65 years,complicated with diabetes,indwelling drainage tube,residual abdominal infection,and WBC level in the occurrence group were higher than those in the non-occurrence group(P<0.05).Logistic regression analysis showed that age(OR=3.025,95%CI:1.453-6.296),diabetes(OR=3.836,95%CI:1.557-9.450),indwelling drainage tube(OR=5.312,95%CI:1.898-14.864)and residual abdominal infection(OR=6.174,95%CI:2.914-13.079)were independent influencing factors for postoperative intestinal adhesion(P<0.05).The corresponding risk rate of the nomogram model based on Logistic results ranged from 0.10 to 0.80,and the C-index was 0.842(95%CI:0.765-0.919).The calibration curve of predicting postoperative intestinal adhesion was close to the ideal curve(P>0.05).The ROC of the training set showed that the sensitivity and specificity of the model in predicting postoperative intestinal adhesion were 85.70%and 88.50%,respectively,and the area under the curve(AUC)was 0.882(P<0.05).In the validation set,the sensitivity,speci-ficity and AUC of ROC curve were 81.30%,84.10%and 0.860(P<0.05),respectively.DCA curve showed that the pre-diction model could obtain the maximum clinical benefit at the threshold probability of 0-0.23.Conclusion:The pre-diction model based on age,diabetes,indwelling drainage tube and residual abdominal infection has a good predictive value for the risk of intestinal adhesion after LC.
