A 14-year-old boy was admitted to the hospital due to a single episode of afebrile seizure and four hours of impaired consciousness. Three months prior to admission, he had a history of bilateral uveitis. Cerebrospinal fluid analysis revealed a mild elevation in white blood cell count. Cranial magnetic resonance imaging and contrast-enhanced scans showed multiple abnormal signals in both cerebral hemispheres, with punctate and nodular enhancement. Susceptibility-weighted imaging revealed multiple punctate hemorrhages within lesions in the bilateral frontal and left parietal lobes, suggestive of vasculitis. Brain biopsy demonstrated inflammatory granulomatous lesions. No secondary causes were identified, and the final diagnosis was granulomatous primary central nervous system vasculitis. The patient's condition improved after treatment with methylprednisolone sodium succinate and mycophenolate mofetil. This report describes a rare case of granulomatous central nervous system vasculitis in a child and provides valuable insights for the diagnosis and treatment of this disease.

OBJECTIVE: To analyze the laboratory detection results of hemolytic disease of the fetus and newborn(HDFN). METHODS: Related test results of 283 newborns and their mothers' blood samples from Kunming Maternal and Child Health Hospital from August 2023 to May 2024 were collected, including mother and child ABO blood group, RhD blood group, as well as 3 tests of HDFN, total bilirubin (TBil) and indirect bilirubin (IBil). RESULTS: 283 were ABO incompatibility, among which 187 were HDFN positive, with a positive rate of 66.08%; the positive rate of HDFN in neonates with antigen-A incompatibility was 74.12%(126/170), the positive rate of HDFN in neonates with antigen-B incompatibility was 53.57%(60/112), which was the highest in neonates with O/A incompatibility ［75.45%(126/167)］, followed by O/B incompatibility［54.55%(60/110)］. Group by age, the positive rates of HDFN in the ≤1 d group, 2 d group, 3 d group, 4 d group, 5 d group and ≥6 d group were 76.03%(111/146), 67.86%(38/56), 57.14%(24/42), 38.46%(5/13), 46.15%(6/13) and 23.08%(3/13), respectively. With the increase of age, the positive rates of HDFN gradually decreased, there was a statistically significant difference between the ≤3 day age group and >3 day age group ( P <0.05). There was no statistically significant difference in TBil and IBil levels between the "direct antibody+indirect antibody+release+" group and the HDFN negative group in newborns. HDFN infants exhibited a rapid increase in bilirubin levels within the first day after birth, with significantly higher TBil and IBil values compared to Non ABO-HDFN infants in the ≤1 day group ( P <0.01). However, the difference of bilirubin levels between the two groups gradually narrowed from 2-6 days after birth, and the difference was not statistically significant (P >0.05). The peak value of TBil and IBil occurred on the 4th day after birth in HDFN infants. CONCLUSION ABO-HDFN is most commonly seen in newborns whose mothers are type-O, and the positive rate was the highest in newborns with O/A incompatibility. The detection rate of HDFN is affected by the age of the newborns, and the two were correlated inversely. ABO-HDFN group developed more rapidly with a higher peak. Therefore, HDFN tests should be carried out as soon as possible for mothers and newborns with incompatible blood types, and appropriate treatment should be provided to prevent complications.

Objective To investigate the attributable risk(AR)of Acinetobacter baumannii(AB)infection in criti-cally ill patients.Methods A multicenter retrospective cohort study was conducted among adult patients in inten-sive care unit(ICU).Patients with AB isolated from sterile body fluid and confirmed with AB infection in each cen-ter were selected as the infected group.According to the matching criteria that patients should be from the same pe-riod,in the same ICU,as well as with similar APACHE Ⅱ score(±5 points)and primary diagnosis,patients who did not infect with AB were selected as the non-infected group in a 1:2 ratio.The AR was calculated.Results The in-hospital mortality of patients with AB infection in sterile body fluid was 33.3％,and that of non-infected group was 23.1％,with no statistically significant difference between the two groups(P=0.069).The AR was 10.2％(95％CI:-2.3％-22.8％).There is no statistically significant difference in mortality between non-infected pa-tients and infected patients from whose blood,cerebrospinal fluid and other specimen sources AB were isolated(P＞0.05).After infected with AB,critically ill patients with the major diagnosis of pulmonary infection had the high-est AR.There was no statistically significant difference in mortality between patients in the infected and non-infec-ted groups(P＞0.05),or between other diagnostic classifications.Conclusion The prognosis of AB infection in critically ill patients is highly overestimated,but active healthcare-associated infection control for AB in the ICU should still be carried out.

Objective To investigate the effects of sulforaphane(SFN)in regulating the macrophage glycolysis via the arachidonate 5-lipoxygenase(ALOX5)/nuclear factor kappa B(NF-κB)signaling pathway on the progression of diabetic nephropathy(DN).Methods Bioinformatics analysis was used to identify the target genes of SFN in the treatment of DN.Human proximal tubular epithelial cell line(HK-2 cells)was induced with 30 mmol/L high glucose(HG)to create an in vitro model of DN.HK-2 cells were divided into the following groups:normal glucose(NG)group,HG group,HG+SFN(3 mmol/L)group,HG+ALOX5 group,HG+SFN(3 mmol/L)+ALOX5 group,HG-treated macrophages+HK-2 group,HG+SFN(3 mmol/L)treated macrophages s+HK-2 group,HG+ALOX5 transfection treated macrophages+HK-2 group,HG+SFN(3 mmol/L)+ALOX5 transfection treated macrophages+HK-2 group.CCK-8 assay was used to detect cell viability,Terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling(TUNEL)method was used to detect cell apoptosis;glucose and lactate levels in the cells were measured using assay kits;Western blot was performed to detect the expression of ALOX5,NF-κB,and glycolysis-related proteins hexokinase-2(HK2),pyruvate kinase M2(PKM2),glucose transporter 1(GLUT1)in each group.Diabetic nephropathy(DN)mouse models were established using streptozotocin(STZ)and treated with SFN(0.5 mg/kg).Various biochemical parameters were measured in the mice,and kidney tissue pathology was examined using H&E staining.Western blot was used to detect the expression of glycolysis-related proteins(HK2,PKM2,GLUT1)in kidney macrophages.Results Bioinformatics analysis revealed ALOX5 as the target gene of SFN in treating DN.Compared to the HG group,SFN treatment enhanced HK-2 cell viability and in-hibited apoptosis(P<0.05);concurrently,SFN treatment suppressed HG-induced macrophage glycolysis-related protein and attenuated macrophage-mediated HK-2 cellular injury(P<0.05).Western blot results showed that SFN inhibited the expression of ALOX5 and NF-κB(P<0.05).The mouse experiment results showed that SFN treatment improved kidney function and pathological changes in the kidney of DN mice,and inhibited the related protein expression of acrophage glycolysis in kidney tissue(P<0.05).Conclusion SFN improves the progression of DN by inhibiting the expression of macrophage glycolysis-related protein through the ALOX5/NF-κB signaling pathway.

Objective To evaluate the bioequivalence of two formulations of minocycline hydrochloride capsules administered orally after fasting administration and fed administration.Methods An open-label,randomized,two-period,self-crossover design was employed to assess the bioequivalence study.Twenty-eight healthy subjects were enrolled in both fasting and fed groups,with each period involving a single administration of either the reference formulation or the test formulation of 50 mg,separated by a washout period of 7 days.The concentration of minocycline in human plasma was determined by HPLC-MS/MS and was used for calculating pharmacokinetic parameters and evaluating the bioequivalence of the test formulation and reference formulation.Results After oral administration of test and reference formulations of minocycline under fasting condition,the Cmax Values of minocycline were(541±137)ng·mL-1 for the test formulation and(558±140)ng·mL-1for the reference formulation.The AUC0-t values were(8 347±1 986)h·ng·mL-1 for the test and(8 205±1 790)h·ng·mL-1 for the reference.The t1/2 values were(18.2±2.84)h for the test and(18.0±3.05)h for the reference.After oral administration of the test and reference formulations of minocycline under fed condition,the Cmax values of minocycline were(349±72.1)ng·mL-1 for the test and(352±73.2)ng·mL-1for the reference.The AUC0-twere(6 428±1 077)h·ng·mL-1 for the test and(6 588±1 118)h·ng·mL-1 for the reference.The t1/2values were(18.5±3.10)h for the test and(18.4±3.21)h for the reference.Under fasting condition,the 90% confidence intervals for the geometric mean ratios of Cmax,AUC0-t,and AUC0-∞ between the test and reference formulations were(90.84%,101.46% ),(95.2%,102.8% ),and(95.31%,102.71% ),respectively.Under fed conditions,the 90% confidence intervals for the geometric mean ratios of Cmax,AUC0-t,and AUC0-∞ between the test formulation and the reference formulation were(94.71%,103.42% ),(95.40%,99.83% ),and(95.79%,100.02% ),respectively.Conclusions Bioequivalence of the two minocycline formulations was demonstrated after fasting administration and fed administration in a healthy Chinese population.

Objective To investigate the risk factors for bronchopulmonary dysplasia(BPD)in twin preterm infants with a gestational age of<34 weeks,and to provide a basis for early identification of BPD in twin preterm infants in clinical practice.Methods A retrospective analysis was performed for the twin preterm infants with a gestational age of<34 weeks who were admitted to 22 hospitals nationwide from January 2018 to December 2020.According to their conditions,they were divided into group A(both twins had BPD),group B(only one twin had BPD),and group C(neither twin had BPD).The risk factors for BPD in twin preterm infants were analyzed.Further analysis was conducted on group B to investigate the postnatal risk factors for BPD within twins.Results A total of 904 pairs of twins with a gestational age of<34 weeks were included in this study.The multivariate logistic regression analysis showed that compared with group C,birth weight discordance of>25%between the twins was an independent risk factor for BPD in one of the twins(OR=3.370,95%CI:1.500-7.568,P<0.05),and high gestational age at birth was a protective factor against BPD(P<0.05).The conditional logistic regression analysis of group B showed that small-for-gestational-age(SGA)birth was an independent risk factor for BPD in individual twins(OR=5.017,95%CI:1.040-24.190,P<0.05).Conclusions The development of BPD in twin preterm infants is associated with gestational age,birth weight discordance between the twins,and SGA birth.

Traditional open head and neck surgery often leaves permanent scars,significantly affecting appearance.The emergence of surgical robots has introduced a new era for minimally invasive surgery.However,the complex anatomy of the head and neck region,particularly the oral and maxillofacial areas,combined with the high costs associated with established systems such as the da Vinci,has limited the widespread adoption of surgical robots in this field.Recently,surgical robotic platform in China has developed rapidly,exemplified by the promise shown by the KangDuo Surgical Robot(KD-SR).Although the KD-SR has achieved some results comparable to the da Vinci surgical robot in urology and colorectal surgery,its performance in complex head and neck regions remains untested.This study evaluated the feasibility,effectiveness,and safety of the newly developed KD-SR-01,comparing it with standard endoscopic systems in head and neck procedures on porcine models.We performed parotidectomy,submandibular gland resection,and neck dissection,collected baseline characteristics,perioperative data,and specifically assessed cognitive workload using the NASA-TLX.None of the robotic procedures were converted to endoscopic or open surgery.The results showed no significant difference in operation time between the two groups(P=0.126),better intraoperative bleeding control(P=0.001),and a significant reduction in cognitive workload(P<0.001)in the robotic group.In conclusion,the KD-SR-01 is feasible,effective,and safe for head and neck surgery.Further investigation through well-designed clinical trials with long-term follow-up is necessary to establish the full potential of this emerging robotic platform.

AIM To improve the quality control method of Zanthoxylum nitidum(Roxb.)DC.METHODS In the TLC qualitative identification of nitidine chloride,chelerythrine and toddalolactone,the analysis was performed on silica gel GF254 TLC plate,chloroform-methanol-ammonia(30∶1∶0.1)was taken as a developing agent.The HPLC fingerprints for Z.nitidum and its adulterants were established.In the HPLC content determination of magnoflorine,nitidine chloride and chelythrine,the analysis was performed on a 30℃ thermostatic Diamonsil Plus column(250 mm×4.6 mm,5 μm),with the mobile phase comprising of acetonitrile-0.1%trifluoroacetic acid flowing at 1.0 mL/min in a gradient elution manner,and the detection wavelength was set at 273 nm.RESULTS The clear TLC plots demonstrated good separation.The similarities of fingerprints for eighteen batches of medicinal materials were 0.484-0.983,Z.nitidum and its adulterants were effectively distinguished.Three constituents showed good linear relationships within their own ranges(R2=1.000 0),whose average recoveries were 98.9%-103.3%with the RSDs of 1.17%-1.96%.CONCLUSION This simple and reproducible can provide a new method for the quality control of Z.nitidum.
