Objective To investigate the associations of variants in signal transducer and activator of transcription 4 (STAT4) in Chinese Han population with rheumatoid arthritis (RA). Methods The study was performed in 228 RA cases and 228 controls. Haplotypes from the HapMap database Chinese population were used to select tag-single-nucleotide polymorphisms (SNPs) (r2=0.9) in STAT4 gene. Twenty-three SNPs located in STAT4 gene were examined by multiplex polymerase chain reaction (PCR) and matrix-assisted laser desorption ionization-time-of-flight mass spectrometry (MALDI-TOF MS). The Hardy-Weinberg equilibrium (HWE) was tested by a chi-square and Fisherˊs analysis. Differences in genotypes of the STAT4 polymorphism variants were evaluated using a Chi-square test. All statistical analyses were done with Haploview 4.1 software. Results Significant difference was detected in three SNPs (rs11685878, rs129888 and rs16833437) in allele frequencies analysis (χ2=6.014 8, 4.024 8, 5.539 1, P<0.05). Association was detected for three SNPs (rs11685878, rs16833437 and rs12988825) in genotype analysis ( χ2=6.814 9, 6.098 7, 6.691 7, P<0.05). Conclusion STAT4 may associate with susceptibility in Chinese Han population.

Objective To investigate the predictive value of baseline neutrophil-to-lymphocyte ratio (NLR) in the curative effect and prognosis of breast cancer patients treated with neoadjuvant chemotherapy.Methods The clinical data of 304 breast cancer patients received neoadjuvant chemotherapy in Beijing Cancer Hospital during 2010 were retrospectively analyzed.The correlations of baseline NLR with clinicopathological parameters of breast cancer patients were analyzed by Wilcox or Kruskal-Wallis tests,and the correlation of NLR with pathologic complete response (pCR) after neoadjuvant chemotherapy was analyzed by the binary logistic regression.The effect of clinic pathological parameters on the disease-free survival(DFS) of the patients was evaluated by the univariable and muhivariable Cox regression models.Results The medians of NLR in pCR + patients (n =62) and pCR-patients (n =242) were 1.76 and 1.72,respectively,and there was no significant difference between themn (P ＞ 0.05).Multivariate analysis indicated that the TNM stage (P ＜ 0.05) and pCR (P ＜ 0.05) were the independent risk factors influencing the prognosis of breast cancer patients.There was no significant correlation between NLR and 5-year DFS (HR=0.842,95％CI=0.566-1.255,P＞0.05).Condusion NLR lacks the predictive value in the curative effect and prognosis of breast cancer patients treated with neoadjuvant chemotherapy,while TNM stage and pCR are the independent risk factors influencing the prognosis of breast cancer patients.

Objective:To analyze the correlation between 1H-MRS in hippocampus and peripheral blood cytokines and T lymphocyte subsets in patients with temporal lobe epilepsy, and to explore the relationship between immune dysfunction and the degree of neuronal injury. Methods:Fifty patients with temporal lobe epilepsy were selected from Affiliated Hospital of Xuzhou Medical University from October 2020 to July 2021.Clinical data of all patients were collected and they were divided into two groups according to MRI results of epileptic sequence: abnormal hippocampal MRI group ( n=20) and normal hippocampal MRI group ( n=30). Bilateral 1H-MRS scanning of hippocampal and detection of T lymphocyte subsets and cytokines in peripheral blood during interictal period were performed in both groups. The levels of hippocampal metabolites NAA, NAA/(Cr+ Cho), T lymphocyte subsets and cytokines in peripheral blood of the two groups were compared.At the same time, the levels of NAA and NAA/ (Cr+ Cho) in the hippocampus on the abnormal side and the normal side in the abnormal hippocampal MRI group were compared within the group. Finally, the correlation between the levels of metabolites NAA, NAA/ (Cr+ Cho) in the hippocampus on the abnormal side obtained by 1H-MRS scanning and T lymphocyte subsets and cytokines in the abnormal group of MRI was analyzed. The data were statistically analyzed by SPSS 26.0 software. Independent sample t-test or Mann-Whitney U test was used for comparison between the two groups. Paired sample t-test was used for intra group comparison of different sides. Spearman correlation analysis was used to analyze the correlation between each index. Results:The NAA and NAA/(Cr+ Cho) values of the abnormal MRI group(normal side NAA: (1.22±0.37), NAA/(Cr+ Cho): (0.56±0.15). abnormal side NAA: (1.02±0.34), NAA/(Cr+ Cho): (0.48±0.13)) were significantly lower than those of the normal MRI group (NAA: (1.51±0.36), NAA/(Cr+ Cho): (0.73±0.19))(NAA: t=2.705, 4.800, both P<0 05; NAA/(Cr+ Cho): t=3.394, 4.914, both P<0 05). The values of NAA and NAA/(Cr+ Cho) in the abnormal side in the MRI abnormal group were significantly lower than those in the normal side( t=6.467, P<0 05). The levels of IL-1β(11.19(3.56, 20.98)pg/ml), IL-5 (3.12(1.86, 6.41)pg/ml), TNF-α(2.55(1.19, 8.28)pg/ml), CD4+ T lymphocytes((43.13±6.82)%) and Th/Ts((1.96±0.66)) in the hippocampal MRI abnormal group were significantly higher than those in normal MRI group (IL-1β: 3.27(1.63, 6.17)pg/ml, IL-5: 1.15(0.96, 2.96)pg/ml, TNF-α: 1.34(1.02, 2.36)pg/ml, CD4+ T: (38.01±7.21)%, Th/Ts: (1.48±0.53))( Z=-3.041, -2.516, -2.496, all P<0.05; t=2.511, 2.810, both P<0 05). The level of CD8+ T ((23.48±5.33)%) in peripheral blood of abnormal MRI group was significantly lower than that of normal group CD8+ T((27.18±6.08)%)( t=2.210, P<0.05). In the abnormal MRI group, the levels of NAA and NAA/ (Cr+ Cho) in the abnormal hippocampus were negatively correlated with the levels of IL-1β, IL-5 and TNF- α ( r=-0.612--0.463, all P<0.05), and positively correlated with CD8+ T lymphocytes ( r=0.537, 0.478, P<0.05). Conclusion:There is neuronal damage and dysfunction in the abnormal hippocampal region of patients with temporal lobe epilepsy with abnormal hippocampal formation, and the degree of neuronal damage is highly correlated with CD8+ T lymphocytes, IL-5, IL-1β and TNF-α in peripheral blood. The imbalance of interictal lymphocyte subsets and chronic inflammatory response may play an important role in the pathogenesis of epilepsy and neuronal injury .

[Objective]To investigate the relationship between platelet activation and traditional Chinese medicine(TCM)syndrome distribution in patients with diabetic peripheral neuropathy(DPN).[Methods]A total of 188 DPN patients admitted to our hospital from February 2020 to December 2022 were collected.The TCM syndrome type usesd the index cluster analysis to draw the cluster diagram.The correspondence between TCM syndrome type and lesion degree was analyzed by simple correspondence analysis,and shown on the two-dimensional plan.It compared the general clinical data,platelet parameters and platelet activation of different TCM syndrome types,so as to explore the relationship between platelet activation and the distribution of TCM syndrome types.[Results]The syndrome types summarized in different positions of the cluster map were different.Among them,D-point interception could be divided into five syndrome types:Qi deficiency syndrome,Yin deficiency syndrome,Yang deficiency syndrome,stagnation of blood stasis syndrome and phlegm-dampness blocking collaterals syndrome.Among the 188 DPN patients,phlegm-dampness blocking collaterals syndrome was found in 18 cases(9.57％),stagnation of blood stasis syndrome in 53 cases(28.19％),Yang deficiency syndrome in 28 cases(14.89％),Yin deficiency syndrome in 39 cases(20.74％),and Qi deficiency syndrome in 50 cases(26.60％).The grade of DPN lesion was grade Ⅰ in 56 cases(29.79％),grade Ⅱ in 76 cases(40.43％),and grade Ⅲ in 56 cases(29.79％).The syndrome of phlegm-dampness blocking collaterals and stagnation of blood stasis in the middle of the two-dimensional projection map did not deviate to a certain grade of DPN lesion degree;Yang deficiency syndrome inclined to grade Ⅲ,Yin deficiency syndrome to grade Ⅱ,and Qi deficiency syndrome to grade Ⅰ.Compared with Qi deficiency syndrome,platelets(PLT),mean platelet volume(MPV),platelet distribution width(PDW),granular membrane protein-140(GMP-140),platelet activating factor(PAF)and E26 transformation specific-l(ETS-l)in patients with Yin deficiency syndrome and Yang deficiency syndrome were significantly higher(P＜0.05),and PLT,MPV,PDW,GMP-140,PAF and ETS-1 in patients with Yang deficiency syndrome were higher than those of Yin deficiency syndrome(P＜0.05).[Conclusion]DPN can be routinely divided into five basic syndrome types:Qi deficiency,Yin deficiency,Yang deficiency,stagnation of blood stasis and phlegm-dampness blocking collaterals.With the development of DPN,TCM syndromes are transformed from Qi deficiency to Yin deficiency to Yang deficiency,while blood stasis and phlegm-dampness blocking collaterals are accompanied by various stages of DPN patients.In the progress of DPN,platelet activation may be involved in the transformation of TCM syndrome types.

Objective:To investigate the clinical and electrophysiological characteristics of facial onset sensory motor neuronopathy (FOSMN) syndrome.Methods:Ten patients diagnosed with FOSMN syndrome in Peking Union Medical College Hospital from January 2012 to December 2022 were included. The clinical and electrophysiological characteristics of patients were analyzed and summarized, and the genetic testing was also performed in these patients.Results:The age of onset was (56.6±6.5) years, and the longest survival duration of disease was 10 years. All patients had numbness around the face and mouth as the first symptom and abnormal blink reflex. A total of 52 sensory nerve conduction nerves were detected, among which 2 median nerves and 2 μlnar nerves showed decreased amplitude of sensory nerve action potential. Needle electromyography showed neurogenic lesions, with both progressive and chronic denervation. Whole exome sequencing identified the heterozygous variant c.272A>C in the exon 4 of the SOD1 gene resulting in the amino acid change p.Asp90Ala in 1 patient. In all patients, the disease progressed relentlessly and eventually led to involvement of respiratory muscle. Conclusion:FOSMN syndrome is characterized by abnormal blink reflex and sometimes abnormal sensory nerve conduction may be shown on electrophysiologic testing.

Objective: To investigate the anatomical features of the safe zone for sacral lateral mass screw placement and find the safe trajectory, so as to provide reference for clinical application. Methods: The three-dimensional computed tomography scan materials of sacrococcygeal vertebrae in 60 patients admitted to the Liaocheng People's Hospital of Shandong Province were analyzed by Mimics software to establish three-dimensional models. There were 33 males and 27 females, aged 25-78 years, with an average age of 45.7 years. After the safe zone was separated from sacral lateral mass model, a maximum cylinder was placed into the safe zone according to its anatomical feature. The cylinder was established as safe trajectory. Anatomical data were measured, including the length and diameter of screw trajectory, the distance between the entry point and the middle jaw, and adjacent upper and lower foramen, as well as the intersection angle between the screw direction and sagittal plane, between the screw direction and the adjacent upper end plate. Results: The restriction factor of screw size on S₁, S₂ lateral mass was transverse diameter, while the restriction factor on S₃, S₄ was the distance between adjacent intervertebral foramen. The maximal length of screw from S₁ to S₄ was 30 mm, 35 mm, 30 mm, 14 mm respectively, while the maximal diameter was 12 mm, 9 mm, 5 mm, 5 mm respectively. The best entry point of S₁ mass screw was lateral to the zygopophysis. The best entry point of S₂-S₄ mass screw was located at the midpoint of a line connecting the lateral edge of adjacent posterior sacral foramen approximately about 2 cm from median sacral crest. The leaning angles of screw was increased successively, and the sagittal plane was slightly inclined. There were significant differences between male and female groups in the leaning angle in S₂ [male: (35.8±1.2)°, female: (37.9±3.7)°] and the distance between entry point and median sacral crest [male: (20.5±1.0)mm, female: (19.1±1.4)mm](P<0.05), while there was no significant difference in other parameters (P>0.05). Conclusions Cylindrical bony channel which is feasible for screw placement can be found in the lateral mass of sacrum. Individualized measurement can provide reference for application of lateral mass screw.
