This paper introduces the academic characteristics of Professor ZHANG Ren in treatment with acupuncture for refractory eye diseases in modern times, guided by "homotherapy for heteropathy" (same therapy for different diseases sharing the same pathogenesis). The refractory eye diseases in modern times include a variety of conditions such as glaucoma, macular degeneration, diabetic retinopathy, high myopia and its complications, dry eye, cortical visual impairment and genetic eye diseases. The same therapy is used because these diseases share the similar location and pathogenesis. Professor ZHANG optimizes the methods of acupoint selection and provides the comprehensive prescriptions, "basic prescription, prescription based on disease differentiation, and supplementary prescription". A variety of acupuncture manipulation techniques are operated in clinical practice, such as compound needling methods, penetration needling, manipulations for promoting qi movement and conducting qi flow. "Early, regular and persistent" treatment is the common requirement with "the same acupoints, the same prescription and the same acupuncture method" as well as at "the same time". It is also proposed that the treatment should be provided flexibly according to the different symptoms, "identifying the differences within similarities".

Objective:To study the comparative genomic characteristics of Marmota himalayana-derived (referred to as marmota-derived) Brucella abortus (B.ab). Methods:The species and types of one strain of marmota-derived Brucella and one strain of human-derived Brucella isolated from the brucellosis epidemic area in Qinghai Province in the same year were identified. Meanwhile, DNA was extracted for whole genome sequencing and comparative genomics analysis (including phylogenetic tree construction, gene family clustering analysis, common/specific gene analysis, and genomic structural variation analysis, etc.). Results:Two Brucella strains from different hosts were identified as B.ab. By constructing a phylogenetic tree, the marmota-derived B.ab strain was grouped with strains from Heilongjiang Province and showed genetic correlation with strains from Russia. Human-derived B.ab strain was classified as a strain in Inner Mongolia Autonomous Region, Hebei Province, Beijing City, and Gansu Province. The multilocus sequence typing (MLST) of the two strains belonged to the ST2 type. Multiple locus variable-number tandem repeat analysis (MLVA) belonged to two new MLVA-8 and MLVA-11 genotypes, which were clustered in two subclusters of the same cluster and clustered with the strains from Inner Mongolia Autonomous Region, Xinjiang Uygur Autonomous Region, and Hebei Province. The pan-genome numbers of the marmota-derived B.ab and human-derived B.ab were 283 and 8, respectively; the number of core genes (common genes) was 68 and 2, respectively; and the number of unique genes was 3 and 4, respectively. The unique gene encoded proteins were inconsistent. In marmota-derived B.ab, the main ones were the ABC transporter ATP-binding protein, N-terminal acetyltransferase, and glucose/galactose transporter. The number of homologous genes of the marmota-derived B.ab and human-derived B.ab was 16 and 20, respectively; the number of translocation and inversion genes was 13 and 8, respectively; the number of deletion mutation genes was 11 and 14, respectively. Pathogenicity analysis showed that both strains had the mprF resistance gene, and the marmota-derived B.ab strain also carried bacitracin and macrolide resistance genes. Conclusions:Brucella exhibits cross-species genetic diversity. The proteins encoded by the unique genes of the marmota-derived B.ab mainly play a role in metabolic and epigenetic regulation. The strains cluster with B.ab strains from northern China, providing a reference for molecular epidemiology and pathogen tracing of B.ab infection.

Objective:To explore the effect of the absent in melanoma 2 (AIM2) -mediated neuroinflammation in noise-induced cognitive dysfunction in rats.Methods:In April 2023, sixteen male Wistar rats were randomly divided into control group and noise group, with 8 rats in each group. The rats in the noise group were placed in 50 cm×50 cm×40 cm transparent boxes and exposed to 100 dB (A) white noise with a sound pressure level of 100 dB (A) (4 h/d for 30 d) . At the same time, rats in the control group were kept in similar boxes with environmental noise less than 60 dB (A) . After 30 days of noise exposure, the Morris water maze experiment was applied to test the learning and memory abilities of the rats; the pathological morphology of hippocampal tissues was observed by Hematoxylin-Eosin (HE) staining. Western blot was used to detect the protein expression levels of AIM2, cysteinyl aspartate specific proteinase-1 (caspase-1) , apoptosis-associated speck-like protein (ASC) , interleukin-1β (IL-1β) , IL-18, ionic calcium-binding articulation molecule-1 (Iba-1) , and glial fibrillary acidic protein (GFAP) . The expression of both Iba-1 and GFAP in hippocampal tissue was assessed by immunohistochemical staining. The co-localization of AIM2 with Iba-1 or GFAP was determined by immunofluorescence double staining.Results:Compared with the control group, the escape latency of rats in the noise group was increased by 16.29 s, 17.71 s, and 20.26 s on days 3, 4, and 5, respectively. On day 6, the noise-exposed rats spent shorter time in the target quadrant and had fewer times in crossing the platform[ (7.25±2.27) s and (1.13±0.64) times] than the control group[ (15.64±3.99) s and (4.25±2.12) times] ( P<0.05) . After noise exposure, hippocampal neurons of rats displayed marked nuclear hyperchromatic and pyknosis phenomenon. The noise-exposed rats had higher numbers of both microglia and astrocytes (27.00±2.65 and 43.33±5.51) in the DG area of the hippocampus relative to the control group (14.67±3.06 and 20.00±4.58) ( P<0.05) . Moreover, the glial cells in the noise group had larger cell cytosol with more and thicker branches. The protein expression levels of inflammatory cytokines Cleaved-IL-1β and Cleaved-IL-18 in the hippocampus of rats in the noise group (1.55±0.19 and 1.74±0.12) were significantly higher than the control group (1.00±0.11 and 1.00±0.13) ( P<0.05) . After noise exposure, the protein expression levels of AIM2, Cleaved-Caspase-1 and ASC (1.19±0.09, 1.34±0.07 and 1.14±0.01) were higher than the control group (1.00±0.07, 1.00±0.14 and 1.00±0.06) and differences between the two groups were statistically significant ( P<0.05) . A significant increase in the number of cells co-localizing AIM2 with Iba-1 or GFAP in the noise group (28.67±4.04 and 40.67±5.13) compared with the control group (15.67±4.04 and 17.67±3.79) , and statistically significant differences were observed between the two groups ( P<0.05) . Conclusion:Noise exposure may activate the AIM2 inflammasome in hippocampal glial cells of rats, releasing excessive inflammatory cytokines and causing neuroinflammation that damages neurons.

A virus was successfully isolated from a sick cat exhibiting clinical signs such as oral mu-cosal ulceration,nasal mucosal redness,and increased nasal secretions utilizing F81 cells.Through a comprehensive analysis as such PCR amplication,sequencing,morphology,serology,and animal re-gression tests,the virus was identified as a feline calicivirus and named FCV-BJ,an inactivated vac-cine was developed from this isolated strain its safety and efficacy were assessed.The results re-vealed that the isolated FCV-BJ strain exhibited characteristic serological and morphological fea-tures consistent with caliciviruses.Furthermore,inoculation of cats with the FCV-BJ demonstrated the strain is highly virulent and the cats manifested the clinical signs of feline calicivirus infection.For the vaccination trial,domestic cats were immunized with inactivated fifth-generation virus cell culture at varying dilutions,followed by a booster immunization after 21 days.Fourteen days after the challenge with the virus,cats immunized with 107.0 TCID50/mL or higher remained largely healthy,while all cats in the control group developed clinical signs of FCV.These findings suggest that the inactivated vaccine derived from the FCV-BJ isolate exhibits strong immunogenicity and protective efficacy at a minimum immunization dose of 107.0 TCID50/mL.This strain holds promise as a candidate for vaccine production,providing a valuable reference and foundation for future re-search and development of feline calicivirus vaccines.

Objective:To explore the clinical benefits of digital simulation surgery in the limited open reduction and intramedullary nail fixation for treatment of proximal humeral fractures.Methods:A retrospective study was conducted to analyze the clinical data of 40 patients who had been treated by limited open reduction and intramedullary nail fixation at Department of Trauma and Orthopedics, The People's Hospital of Weifang from June 2020 to September 2022 for 3-part proximal humeral fractures by Neer classification. The patients were assigned into 2 groups according to different preoperative strategies. In the observation group of 17 patients [4 males and 13 females with an age of (66.9±8.6) years], the angle of intramedullary nail placement into the humeral head and the sequence of reduction and fixation were simulated in the preoperative digital simulation surgery. In the control group of 23 patients [7 males and 16 females with an age of (63.0±8.6) years], routine reduction and fixation were performed based on the preoperative shoulder joint CT images and intraoperative fluoroscopy without preoperative digital simulation surgery. The 2 groups were compared in terms of operation time, intraoperative blood loss, intraoperative fluoroscopy frequency, incidence of postoperative complications, fracture healing time, active range of motion of the shoulder joint at the last follow-up, as well as the intramedullary nail heights, humeral neck-shaft angles, Constant shoulder function scores, and visual analogue scale (VAS) pain scores at 3 days, 12 weeks, and 24 weeks postoperatively.Results:The 2 groups were comparable because there were no statistically significant differences in the preoperative general data between them ( P>0.05). The operation time in the observation group [(57.5±6.2) min] was significantly shorter than that in the control group [(71.3±10.2) min], and the intraoperative fluoroscopy frequency in the former [(28.5±4.4) times] significantly lower than that in the latter [(45.4±2.6) times] ( P<0.05).The 2 groups were followed up for (15.0±1.6) months. For the observation and the control groups, respectively, the fracture healing time was (10.5±2.4) weeks and (10.0±2.0) weeks, showing no statistically significant differences between groups ( P>0.05). There were no statistically significant differences between the 2 groups in the intraoperative blood loss, or in the intramedullary nail heights, humeral neck-shaft angles, Constant shoulder function scores, or VAS pain scores at 3 days, 12 weeks, or 24 weeks postoperatively, or in the active range of motion of the shoulder joint at the last follow-up ( P>0.05). Complications such as infection, humeral head necrosis, and screw removal occurred in none of the patients. Conclusion:In the treatment of proximal humeral fractures, before the routine limited open reduction and intramedullary nail fixation, digital simulation surgery can be performed to reduce the operation time and fluoroscopy frequency without sacrifice of the therapeutic efficacy.

Treatment of advanced non-small cell lung cancer (NSCLC) patients with epidermal growth factor receptor (EGFR) mutation with EGFR-tyrosine kinase inhibitors (EGFR-TKIs) can achieve good disease control, but it will inevitably produce drug resistance. About 3%-10% of the resistance mechanism is small cell transformation. Two cases of stage IV lung adenocarcinoma with EGFR mutation were reported and the disease was controlled after EGFR-TKIs treatment. In case 1, progression-free survival (PFS) before small cell carcinoma transformation was 16 months, and in case 2, PFS before small cell carcinoma transformation was 24 months. Subsequent biopsy after disease progression indicated a shift to small cell lung cancer. Case 1 PFS after small cell carcinoma transformation was 6 months, and case 2 PFS after small cell carcinoma transformation was 8 months, and overall survival (OS) was 36 months, which significantly prolonged the patient's survival. At the same time, the literature of such drug resistance mutations was reviewed. For patients with advanced NSCLC with sensitive mutations, it is necessary to conduct secondary histopathological tests after TKIs treatment resistance, and select subsequent treatment according to different resistance mechanisms for the whole course of disease management.

Objective:To analyze the risk factors of bronchopulmonary dysplasia(BPD)in very preterm infants(VPI), and to provide scientific basis for the prevention and treatment of BPD in VPI.Methods:A prospective multicenter study was designed to collect the clinical data of VPI in department of neonatology of 28 hospitals in 7 regions from September 2019 to December 2020.According to the continuous oxygen dependence at 28 days after birth, VPI were divided into non BPD group and BPD group, and the risk factors of BPD in VPI were analyzed.Results:A total of 2 514 cases of VPI including 1 364 cases without BPD and 1 150 cases with BPD were enrolled.The incidence of BPD was 45.7%.The smaller the gestational age and weight, the higher the incidence of BPD( P<0.001). Compared with non BPD group, the average birth age, weight and cesarean section rate in BPD group were lower, and the incidence of male infants, small for gestational age and 5-minute apgar score≤7 were higher( P<0.01). In BPD group, the incidences of neonatal respiratory distress syndrome(NRDS), hemodynamically significant patent ductus arteriosus, retinopathy of prematurity, feeding intolerance, extrauterine growth restriction, grade Ⅲ~Ⅳ intracranial hemorrhage, anemia, early-onset and late-onset sepsis, nosocomial infection, parenteral nutrition-associated cholestasis were higher( P<0.05), the use of pulmonary surfactant(PS), postnatal hormone exposure, anemia and blood transfusion were also higher, and the time of invasive and non-invasive mechanical ventilation, oxygen use and total hospital stay were longer( P<0.001). The time of starting enteral nutrition, cumulative fasting days, days of reaching total enteral nutrition, days of continuous parenteral nutrition, days of reaching 110 kcal/(kg·d) total calorie, days of reaching 110 kcal/(kg·d) oral calorie were longer and the breastfeeding rate was lower in BPD group than those in non BPD group( P<0.001). The cumulative doses of amino acid and fat emulsion during the first week of hospitalization were higher in BPD group( P<0.001). Multivariate Logistic regression analysis showed that NRDS, invasive mechanical ventilation, age of reaching total enteral nutrition, anemia and blood transfusion were the independent risk factors for BPD in VPI, and older gestational age was the protective factor for BPD. Conclusion:Strengthening perinatal management, avoiding premature delivery and severe NRDS, shortening the time of invasive mechanical ventilation, paying attention to enteral nutrition management, reaching whole intestinal feeding as soon as possible, and strictly mastering the indications of blood transfusion are very important to reduce the incidence of BPD in VPI.
