Objective To observe the efficacy of combination therapy of calcium dobesilate dispersible and monosialotetrahexosylganlioside sodium on interleukin-6 (IL-6) and monocyte chemotactic protein-1 (MCP-1) in elderly patients with painful diabetic peripheral neuropathy.Methods From January 2012 to May 2017,in the Second People's Hospital of Lianyungang 70 patients of painful diabetic peripheral neuropathy,aged ≥60 years,were analyzed in this study.They were randomly divided into observation group (35 cases) and control group (35 cases).The observation group was treated with 40mg monosialotetrahexosylganlioside sodium dissolved in 250mL physiological saline,intravenous infusion per day,and oral calcium dobesilate dispersible 0.5g twice a day for two weeks.The control group was treated with methylcobalamin injection 0.5mg per day for two weeks.The clinical treatment effects and levels of IL-6 and MCP-1 were observed and compared between the two groups.Results After two weeks of treatment,the MDNS and MNSI scores of the observation group [(13.09 ± 5.38)points,(2.53 ± 1.19)points] were significantly lower than those of the control group [(18.31 ± 6.13) points,(4.19 ± 1.05) points,t =2.036,2.365,all P ＜ 0.05] and those before treatment [(21.26 ± 4.28) points,(5.40 ± 0.89) points,t =3.251,3.698,all P ＜ 0.05].The VAS-PI scores in the observation group [(6.24 ± 1.25) points,(4.13 ± 1.69) points] were significantly lower than those in the control group[(7.26 ± 1.28) points,(6.34 ± 2.65) points] at the first and second week (t =3.265,5.395,all P ＜ 0.05).The serum levels of inflammatory cytokines IL-6 and MCP-1 in the observation group [(15.16 ±0.88) ng/L,(157.19 ± 11.22) ng,/L] were significantly lower than those in the control group[(17.87 ± 1.19) ng/L,(198.21 ± 12.07)ng/L,t =2.152,1.365,all P ＜0.05]and those before treatment[(20.26 ± 1.05) ng/L,(260.44 ± 13.63) ng,/L,t =1.235,0.965,all P ＜ 0.05].Conclusion Combination of calcium dobesilate and mono-sialotetrahexosyl ganglioside may alleviate the sensory and pain sensations in patients with painful diabetic peripheral neuropathy,possibly by reducing the level of inflammatory cytokines IL-6 and MCP-1.

Objective To observe the multimodal imaging characteristics of multiple evanescent white dot syndrom (MEWDS).Methods This was a retrospective series case study.Eighteen patients (18 eyes) diagnosed with MEWDS in Eye Center of The Second People's Hospital of Foshan from September 2015 to April 2017 were enrolled in this study.There were 12 females and 6 males,with the mean age of 35.9 years.The disease course ranged from 3 to 90 days,with the mean of 14 days.All the patients underwent BCVA,slit-lamp microscope with +90D preset lens,fundus photography,spectral domain OCT (SD-OCT) and FAF examinations.FFA was simultaneously performed in 6 eyes,FFA and ICGA were simultaneously performed in 12 eyes.Ten patients received the treatment of glucocorticoids and vasodilator substance,and other 8 patients without any treatment.The follow-up duration was 4.5 months.The multimodal imaging characteristics were reviewed and analyzed.Results Fundus color photography showed a variable number of small dots and large spots lesions (14 eyes),and/or fovea granularity (7 eyes) and disk swelling (5 eyes).A variable number of little dots and larger spots lesions showed respectively in FFA,FAF and ICGA were needle-like dots distributed in a wreathlike pattern and a large plaque occasionally confluent of early highly fluorescent,highly autofluorescence and hypofluoresence.Combined hypofluorescent spots with overlying dots were observed in 10 eyes of the late stages of the ICGA.Black lesions in the gray background show in ICGA were the most obvious and the most extensive,gray-white lesions in the gray-black show in FAF were the second,light gray-black lesions in the gray show in FFA were the least.Gray-white lesions in an orange background show in fundus photography were not obvious and transient.SD-OCT showed disruption of the ellipsoid zone and/or accumulations of hyperreflective material from the ellipsoid layer toward the outer plexiform layer and vitreous cells.During the period of following-up,some patients were prescribed low-dose glucocorticoid and some not,almost all the patients except one patient experienced recovery in BCVA and the lesions in fundus imaging.Conclusions The lesions in MEWDS eyes in modern multimodal imaging modalities among fundus photography (fovea granularity),FFA (needle-like dots distributed in a wreathlike pattern and a large plaque occasionally confluent of early highly fluorescent),ICGA (flake hypofluorescent) and SD-OCT (disruption of the ellipsoid zone) showed good consistency.Almost eyes were recovery.

Objective To investigate the relationship between plasma tau protein, phosphorylated tau protein (p-tau) protein and cognitive function in subjects with generalized brain atrophy. Methods A total of 100 subjects with moderate and severe brain atrophy were divided into two groups according to cognitive function: normal group (n=50 cases) and dementia group (n=50 cases). And their gender, age, educational level, etc. are recorded. The tau protein and p-tau protein content in plasma were measured by double antibody sandwich enzyme-linked immunosorbent assay (ELISA). The differences between plasm tau and p-tau protein expression and their relationship with cognitive function were analyzed. Results Plasma tau protein and p-tau protein levels were significantly higher (P<0.05) in the dementia group [(210.92±43.79)pg/mL、(81.15±16.85)pg/mL] than in the normal group[(210.92±43.79)pg/mL、(81.15±16.85)pg/mL]. Plasma tau protein and p-tau protein levels were negatively correlated with the MMSE score (P<0.05) and had no significant correlation with the degree of brain atrophy (P>0.05). Conclusion Cognitive impairment may be associated with elevated tau protein levels in patients with extensive brain atrophy.

Background::The goal of the assisted reproductive treatment is to transfer one euploid blastocyst and to help infertile women giving birth one healthy neonate. Some algorithms have been used to assess the ploidy status of embryos derived from couples with normal chromosome, who subjected to preimplantation genetic testing for aneuploidy (PGT-A) treatment. However, it is currently unknown whether artificial intelligence model can be used to assess the euploidy status of blastocyst derived from populations with chromosomal rearrangement.Methods::From February 2020 to May 2021, we collected the whole raw time-lapse videos at multiple focal planes from in vitro cultured embryos, the clinical information of couples, and the comprehensive chromosome screening results of those blastocysts that had received PGT treatment. Initially, we developed a novel deep learning model called the Attentive Multi-Focus Selection Network (AMSNet) to analyze time-lapse videos in real time and predict blastocyst formation. Building upon AMSNet, we integrated additional clinically predictive variables and created a second deep learning model, the Attentive Multi-Focus Video and Clinical Information Fusion Network (AMCFNet), to assess the euploidy status of embryos. The efficacy of the AMCFNet was further tested in embryos with parental chromosomal rearrangements. The receiver operating characteristic curve (ROC) was used to evaluate the superiority of the model. Results::A total of 4112 embryos with complete time-lapse videos were enrolled for the blastocyst formation prediction task, and 1422 qualified blastocysts received PGT-A ( n = 589) or PGT for chromosomal structural rearrangement (PGT-SR, n = 833) were enrolled for the euploidy assessment task in this study. The AMSNet model using seven focal raw time-lapse videos has the best real-time accuracy. The real-time accuracy for AMSNet to predict blastocyst formation reached above 70% on the day 2 of embryo culture, and then increased to 80% on the day 4 of embryo culture. Combing with 4 clinical features of couples, the AUC of AMCFNet with 7 focal points increased to 0.729 in blastocysts derived from couples with chromosomal rearrangement. Conclusion::Integrating seven focal raw time-lapse images of embryos and parental clinical information, AMCFNet model have the capability of assessing euploidy status in blastocysts derived from couples with chromosomal rearrangement.

【Objective】 To analyze the correlation between platelet distribution width (PDW) and hyperuricemia (HUA). 【Methods】 For this study we recruited 4 885 teaching and administrative staff of Xi’an Jiaotong University who took the physical examination in 2020 and met the requirements. The basic information, blood routine and serum biochemical index results were collected and analyzed retrospectively. Data were sorted by gender, and the serum UA level and the prevalence of HUA in different PDW quartiles were compared after dividing PDW into quartiles. The association of PDW with other indexes including age, serum biochemical indexes and blood routine indexes was analyzed. Then, the factors related to HUA in different genders were analyzed, and the independent influence of PDW on HUA was further analyzed. 【Results】 The serum UA level and prevalence of HUA were on the increase among different PDW quartiles both in two genders, and PDW level was positively correlated with serum UA level (P<0.05). In addition, PDW was correlated with age, fasting blood glucose, indicators related to liver and kidney function, and certain indexes of blood lipid and blood routine tests. Among the above indicators, glutamic-pyruvic transaminase, glutamic oxalacetic transaminase, creatinine, urea, white blood cell count, hematocrit, and blood lipid were all significantly associated with HUA in both genders (P<0.05). In addition, HUA significantly associated with platelet count in males (P<0.05), but with age, fasting blood glucose, hemoglobin, red blood cell distribution width, and PDW in females (P<0.05). After excluding the above confounding factors, the risk of HUA in males with high levels of PDW was still significantly increased (P<0.05), but there was no significant difference in females (P>0.05). 【Conclusion】 PDW is correlated with HUA, and PDW may be an independent risk factor for HUA in males. However, further study is needed.

In order to meet the accuracy requirements of hospitals for abnormal detection of fetal monitor data,a hospital fetal monitor data anomaly detection method based on Euclidean distance was proposed.In this method,according to the abnormal detection method of fetal monitor data in hospitals,the ultrasound Doppler detector was used to collect fetal heart rate signal data,and the fetal heart rate signal denoising method based on adaptive filtering was used to remove the noise components of the collected fetal heart rate signal.The denoised fetal heart rate signal was used as the identification sample of the abnormal fetal heart rate signal identification method based on Euclidean distance method.The Euclidean distance Euclidean distance between the denoised fetal heart rate signal and the normal fetal heart rate signal was analyzed by combining the Euclidean distance method and the strong classifier to analyze whether the virtual sinusoidal distance between the denoised fetal heart rate signal and the normal fetal heart rate signal was greater than the tuned Euclidean distance threshold.Fetal heart rate signal samples greater than the threshold were classified and diagnosed as abnormal monitoring data.The fetal heart rate information collected by the fetal monitor in the hospital was accurate,and the abnormal detection results were valid and reliable.
