ABSTRACT
Objective To investigate the clinical manifestation and imaging features of diabetic striatopathy(DS).Methods A retrospective analysis was conducted on the clinical,laboratory,and imaging data of 8 patients with DS,which was then summarized in conjunction with relevant literature.Results Random blood glucose(8.39-24.80 mmol/L)and glycated hemoglobin(HbA1c)(9.0%-21.50%)were elevated in 8 patients.One case had positive urine ketone bodies(++),while 7 cases had negative urine ketone bodies(-).Hemichorea was present in 7 cases,while 1 case did not exhibit hemichorea.A total of 7 cases showed unilateral striatum T1WI hyperintensity on MRI,and 8 cases showed iso/hyper-density on CT scans.Following blood glucose control and other related treatments,involuntary movement disappeared in 2 cases,and symptoms improved in 5 cases.Conclusion DS mainly occurs in diabetic patients with poorly controlled blood glucose,presenting with typical clinical manifestation and neuroimaging features.It manifests exclusively in the contralateral striatum of the affected limb.The diagnosis should be based on a combination of clinical,laboratory,and imaging findings to prevent missed or misdiagnoses.
ABSTRACT
ObjectiveTo investigate the depression status and its influencing factors in HIV/AIDS patients receiving antiviral therapy. MethodsFrom July 2022 to September 2022， successive sampling method was used to recruit HIV/AIDS patients receiving antiviral therapy from antiviral treatment institutions in Nanjing， and they were instructed to fill out anonymous questionnaires. The questionnaire collected the basic information of patients， and depression， HIV stigma score and social support level were investigated by Patient Health Questionnaire-9 （PHQ-9）， Berger HIV stigma scale （BHSS） and Multidimensional Scale of Perceived Social Support （MSPSS）. Multivariate Logistic regression was used to analyze the influencing factors of depression. ResultsA total of 1879 valid questionnaires were collected in this study， and the detection rate of depression was 50.1%. The results of multivariate logistic analysis showed that compared with patients with middle school or below， the risk of depression was lower for those with postgraduate or above ［OR=0.534， 95%CI （0.341， 0.835）， P=0.006］. Compared with antiviral therapy duration<1 year， antiviral therapy duration for 1 to 5 years ［OR=0.729， 95%CI （0.536， 0.991）］， >5 to 10 years ［OR=0.516， 95%CI （0.379， 0.702）］， >10 years ［OR=0.603， 95%CI （0.375， 0.969）］ was associated with a lower risk of depression. High level of social support was a protective factor for depression in HIV/AIDS patients compared with middle and low level of social support ［OR=0.430， 95% CI（0.349， 0.530）， P < 0.001］. There was a higher risk of depression with side effects than without side effects ［OR=2.260， 95%CI （1.833， 2.786）， P < 0.001］. The higher the score on the HIV stigma scale， the higher the possibility of depression was. ConclusionThe detection rate of depression of patients receiving antiviral therapy in Nanjing is high. After starting antiviral therapy， we should strengthen the monitoring of side effects and psychological status of patients， carry out psychological intervention， alleviate psychological problems， and improve the quality of life of patients receiving antiviral therapy.
ABSTRACT
OBJECTIVE To explore the protective mechanism of amifostine on acute radiation injury mice. METHODS Thirty C57BL/6J mice were randomly divided into normal control group， model group and amifostine group （150 mg/kg）， with 10 mice in each group. Thirty minutes before irradiation， the mice in the amifostine group were intraperitoneally injected with amifostine； normal control group and model group were given constant volume of normal saline intraperitoneally； then acute radiation injury was induced by 4 Gy X-ray radiation in both model group and amifostine group. The white blood cell count （WBC）， platelet count and red blood cell （RBC） count in mice were detected 2 hours before irradiation and on days 1， 4， 7， 10 and 14 after irradiation； the changes in the proportion of WBC （neutrophils， lymphocytes and monocytes） on the 7th day after irradiation were analyzed. The 16S rRNA high-throughput sequencing was used to analyze the structure of gut microbiota in mice feces on the 7th day after irradiation， then its correlation with WBC was analyzed. RESULTS The counts of WBC on the 1st， 4th， 7th and 10th day after irradiation， platelet count on the 10th day after irradiation and RBC count on the 1st day after irradiation in the amifostine group were significantly higher than those in model group （P＜0.05）. Compared with normal control group，β diversity of gut microbiome showed significant change， relative abundance of Firmicutes increased and that of Bacteroidetes decreased in model group. Amifostine could reverse the change in β diversity of gut microbiome， and the relative abundance of Bacteroidetes and Firmicutes. The model group consisted of four distinct species， namely Allobaculum， Erysipelotrichia， Erysipelotrichales and Erysipelotrichaceae， which were significantly negatively correlated with the proportion of peripheral blood lymphocytes （P＜0.01）； amifostine group consisted of two distinct species， namely Lactobacillus murinus and L. crispatus， which were significantly negatively correlated with the proportion of neutrophils （P＜0.05）. CONCLUSIONS Amifostine significantly improves irradiation-induced injury by regulating dysbiosis of LY201816） gut microbiota.
ABSTRACT
Squamosa promoter binding protein-like (SPL) family is a group of important transcription factors involved in the regulation of plant growth and development and the response to environmental stress, but there are few studies in perennial fruit trees such as citrus. In this study, Ziyang Xiangcheng (Citrus junos Sib.ex Tanaka), an important rootstock of Citrus, was used as the material for analysis. Based on plantTFDB transcription factor database and sweet orange genome database, 15 SPL family members were genome-widely identified and cloned from Ziyang Xiangcheng, and named CjSPL1-CjSPL15. Sequence analysis showed that the open reading frame (ORF) length of CjSPLs ranged from 393 bp to 2 865 bp, encoding 130-954 amino acids. Phylogenetic tree divided 15 CjSPLs into 9 subfamilies. Gene structure and conserved domain analysis predicted 20 different conserved motifs and SBP basic domains. Analysis of cis-acting promoter elements predicted 20 different promoter elements, including those related to plant growth and development, abiotic stress and secondary metabolites. The expression patterns of CjSPLs under drought, salt and low temperature stresses were analyzed by real-time fluorescence quantitative PCR (qRT-PCR), and many CjSPLs were significantly up-regulated after stress treatment. This study provides a reference for further study on the function of SPL family transcription factors in citrus and other fruit trees.

Objective:To investigate the clinical characteristics of patients with multiple myeloma (MM) combined with kidney injury and the risk factors associated with the occurrence of kidney injury.Methods:The clinical data of 96 newly treated MM patients in Heze Municipal Hospital from January 2017 to June 2021 were retrospectively analyzed, and the patients were divided into the kidney injury group (33 cases) and the non-kidney injury group (63 cases) based on whether the blood creatinine was >177 μmol/L at the time of diagnosis. The general data and laboratory results of the two groups were compared. The risk factors for kidney injury in MM patients were analyzed by logistic regression method, and the receiver operating characteristic (ROC) curve was drawn to assess the predictive value of each risk factor for the occurrence of kidney injury in MM patients.Results:Compared with the non-kidney injury group, hemoglobin was lower in the kidney injury group, and white blood cell count, blood uric acid, urea nitrogen, β 2-microglobulin (β 2-MG), cystatin C, the proportion of patients with light chain type, and the proportion of patients with international staging system (ISS) stage Ⅲ were higher in the kidney injury group, and the differences were statistically significant (all P < 0.05). Thirty-four patients underwent fluorescence in situ hybridization (FISH) test, and 22 cases (64.7%) had abnormal results. In the non-kidney injury group, genetic testing were performed in 26 cases, and the results were abnormal in 14 cases, including 11 cases (42.3%) of IgH rearrangement, 4 cases (15.4%) of RB1 deletion, 4 cases (15.4%) of 1q21 amplification, and 1 case (3.8%) of P53 deletion; in the kidney injury group, 8 cases underwent genetic testing, and all results were abnormal, including 6 cases (75.0%) of IgH rearrangement, 5 cases (40.0%) of RB1 deletion, and 2 cases (25.0%) of 1q21 amplification. The rate of RB1 mutation in the kidney injury group was higher than that in the non-kidney injury group, and the difference was statistically significant ( χ2 = 4.43, P = 0.035). Logistic regression analysis showed that elevated blood uric acid ( OR = 1.009, 95% CI 1.002-1.016, P = 0.015) and ISS stage Ⅲ ( OR = 16.401, 95% CI 1.174-229.164, P = 0.038), elevated white blood cell count ( OR = 1.833, 95% CI 1.020-3.294, P = 0.043), elevated β 2-MG ( OR = 1.320, 95% CI 1.009-1.728, P = 0.043), and decreased hemoglobin ( OR = 0.900, 95% CI 0.832-0.922, P = 0.008) were independent risk factors for the development of kidney injury in MM patients. According to the area under the ROC curve (AUC), blood uric acid (AUC = 0.775, 95% CI 0.675-0.875, P < 0.001), white blood cell count (AUC = 0.696, 95% CI 0.583-0.809, P = 0.002), β 2-MG (AUC = 0.822, 95% CI 0.732-0.911, P < 0.001), hemoglobin (AUC = 0.755, 95% CI 0.652-0.857, P < 0.001), and ISS stage Ⅲ (AUC = 0.763, 95% CI 0.669-0.856, P < 0.001) had predictive value for kidney injury in MM. Conclusions:MM patients have a high incidence of combined kidney injury, and active monitoring and control of risk factors may improve the outcome and prognosis of patients.
ABSTRACT
Objective:To investigate the diagnostic value of neutrophil CD64 index (nCD64) in disseminated nontuberculous mycobacteria (NTM) infection.Methods:Thirty-six patients with NTM infection from January 2020 to June 2021 in Huashan Hospital, Fudan University were included. Patients were classified into groups of disseminated infection and focal infection according to their medical history and discharge diagnosis. The expressions of nCD64 in patients with focal infection and disseminated infection before treatment were collected and analyzed. Statistical analysis was performed using the Mann-Whitney U test, and the diagnostic value of nCD64 for disseminated NTM infection was analyzed using the receiver operator characteristic curve (ROC curve). Results:Among the 36 patients with NTM infection, 18 cases were focal infection (due to the low white blood cell count of the patient with myelodysplastic syndrome, the detection results were biased, which were excluded from the subsequent analysis) and 18 cases were disseminated infection. The expression of nCD64 in focal infection was 0.72(0.50, 1.55), and that in disseminated infection was 13.63(6.77, 32.31). The difference was statistically significant ( U=15.50, P<0.001). Using focal infection as a control, the area under the ROC curve for the operational characteristics of the subjects was 0.949 3 for disseminated NTM infection. The diagnostic cut-off value of nCD64 was 3.06, with the sensitivity and specificity of the disseminated NTM infection were 88.89% and 100.00%, respectively. Conclusions:In patients with NTM infection before effective treatment, the diagnostic cut-off value of nCD64 of 3.06 has high sensitivity and specificity, which is useful for the aided diagnosis of disseminated NTM infection.
ABSTRACT
Objective:To explore the correlation of serum adiponectin (APN) , D-dimer (D-D) and neutrophil-to-lymphocyte ratio (NLR) levels with disease severity and prognosis in patients with diabetic foot ulcer infection.Methods:92 patients with diabetic foot ulcer infection in the Nantong Third Hospital Affiliated to Nantong University from Feb. 2020 to Feb. 2021 were selected, and they were divided into mild ( n=30) , moderate ( n=44) and severe ( n=18) patients according to the severity of the disease. The serum APN, D-D and NLR levels in patients with different severity were compared, the relationship between serum APN, D-D and NLR levels and disease severity in patients with diabetic foot ulcer infection were analyzed. Patients were followed up for 1 year, and the prognosis of the patients was counted. Factors affecting serum APN, D-D and NLR levels in patients with diabetic foot ulcer infection were analyzed, and the receiver operating curve (ROC) was used to analyze the value of serum APN, D-D and NLR levels in predicting poor prognosis of patients. Results:There were significant differences in serum APN, D-D and NLR levels in patients with different severity ( P<0.05) . APN level in severe patients was 5.35±0.98, in moderate patients was 7.64±1.25, both lower than that of the mild patients 9.19±1.73 ( P<0.05) . Serum APN level in severe patients was lower than that in moderate patients ( P<0.05) . Serum D-D and NLR levels were 3.49±0.72 and 2.86±0.58 in severe patients, respectively; and they were 3.02±0.63 and 2.24±0.46 in moderate patients, higher than that of mild patients 2.43±0.51; 1.71±0.33 ( P<0.05) . The levels of serum D-D and NLR in severe patients were higher than those in moderate patients ( P<0.05) . Spearman correlation analysis showed that the severity of the disease was negatively correlated with serum APN levels ( r=-0.414, P<0.001) , and positively correlated with serum D-D and NLR levels in patients with diabetic foot ulcer infection ( r=0.387, P<0.001; r=0.461, P<0.001) . Univariate analysis showed that the proportion of severe disease, serum fasting blood glucose, glycosylated hemoglobin, fibrinogen, D-D and NLR levels in patients with poor prognosis were higher than those in patients with good prognosis ( P<0.05) , and the APN level in patients with poor prognosis was lower than that in patients with good prognosis ( P<0.05) . Logistic multivariate regression analysis showed that severe disease, serum glycosylated hemoglobin, APN, D-D, and NLR levels were independent risk factors for poor prognosis in patients with diabetic foot ulcer infection ( P<0.05) . ROC analysis showed that the optimal cut-off points of serum APN, D-D and NLR levels for predicting poor prognosis of patients were 5.73 mg/L, 3.06 mg/L, 2.12, the sensitivity was 78.57%, 82.14%, 85.71%, the specificity was 76.56%, 67.19%, 73.44%, the area under the curve (AUC) was 0.793, 0.784, 0.818, the specificity and AUC of the three were 98.44 %, 0.918, respectively. Conclusions:Serum APN, D-D and NLR levels are related to the severity of the disease in patients with diabetic foot ulcer infection. Clinical detection of serum APN, D-D and NLR levels can be used as sensitive indicators to predict poor prognosis.
ABSTRACT
AIM: To assess the bioequivalence of oral dexamethasone acetate tablets between the test and reference formulations in healthy adult Chinese subjects on an empty stomach and after meals. METHODS: A randomized, open, single-dose, two-cycle double crossover bioequivalence study was followed. Twenty-four healthy subjects were included in the fasting group, and 32 healthy subjects were included in the postprandial group, taking 2 tablets (0.75 mg/tablet) of the test formulation (T) or 3 tablets (0.50 mg/tablet) of the reference formulation (R) per cycle for two cycles. The concentrations of dexamethasone acetate in human plasma were determined using liquid chromatography-mass spectrometry, and the pharmacokinetic parameters were calculated according to the non-atrial model using WinNonlin 8.0 software.The bioequivalence of both the test formulation and the reference formulation was evaluated. RESULTS: The pharmacokinetic parameters after oral administration of dexamethasone acetate tablets in a fasted state in subjects with the reference formulation are as follows: Tmax 1.13 (0.50, 4.00) and 1.00 (0.50, 5.00) h, AUC0-t (72.25±21.55) and (69.23±17.76) ng · mL
ABSTRACT
Objective:To investigate the application of system relaxation training on the posttraumatic stress disorder for the families of burned children, so as to provide a basis for the application of valid nursing in children families.Methods:A total of 80 cases of burned children in Children′s Hospital of Nanjing Medical University and corresponding 80 households were recruited and divided into the observation group and the control group with 40 cases each group. The patients and households from January 2019 to May 2019 in the control group received routine care, while the patients and households from February 2020 to June 2020 in the observation group received system relaxation training based on the routine care for four days. The posttraumatic stress disorder and uncertainty in illness of children families before and after intervention were evaluated by Posttraumatic stress Checklist-Civilian version(PLC-C) and Mishel Uncertainty in Illness Scale-Family Member form(MUIS-FM) and compared between the two groups.Results:There was no significant difference in the scores of PLC-C and MUIS-FM before intervention in the households between the two groups( P>0.05). After intervention, the scores of re-experiencing symptoms, avoidance/numbing, increased arousal symptoms and total PTSD scores in the households were (8.40 ± 1.79), (14.35 ± 2.85), (8.25 ± 1.28), (31.10 ± 3.52) points in the observation group and (11.28 ± 2.37), (16.75 ± 2.09), (9.10 ± 1.93), (37.13 ± 4.40) points in the control group, the differences were statistically significant ( t values were -6.76 - -2.32, all P<0.05). After intervention, the scores of ambiguity, deficit information and total MUIS-FM scores of the households were (37.08 ± 6.58), (20.15 ± 4.38), (84.38 ± 6.90) points in the observation group and (41.13 ± 6.54), (22.05 ± 3.32), (90.13 ± 7.85) points in the control group, the differences were statistically significant ( t =-2.76, -2.19, -3.48, all P<0.05). Conclusions:System relaxation training can alleviate posttraumatic stress disorder and reduce uncertainty in illness of the families of burned children.
ABSTRACT
Objective:To retrospectively analyze the treatment of 25 cases of lower necrotizing fasciitis.Methods:A total of 25 patients with lower limb necrotizing fasciitis (13 males and 12 females), with mean age 63 years old (48-75 years old) in Dalian Municipal Central Hospital from September 2016 to December 2020. After admission, the patient′s general physical condition was strictly evaluated, the relevant preoperative examination was improved, and the necrotizing fasciitis laboratory risk index (LRINEC) score was performed. In the absence of surgical contraindication, multiple debridement was performed, leaving the necrotic tissue removed for general bacterial culture and drug sensitivity test in parallel. After debridement, eight patients showed a large area of skin necrosis, and amputation was selected. The other 17 patients chose limb protection treatment after debridement, and adopted debridement and free skin grafting. After surgery, patients were encouraged to strengthen rehabilitation exercise to restore limb function to the maximum extent.Results:With followed up 0.6 to 3.0 years, with an average of 1.8 years. Methods include outpatient return visit, WeChat contact or telephone inquiry. The skin survived in 17 patients with mean healing time (27.5 ± 6.9) d. Eighteen patients were multiple bacterial infections and seven patients were single bacterial infections. All patients had no joint dysfunction caused by scar contracture, and reinfection in the skin grafting area.Conclusions:Necrotizing fasciitis requires early diagnosis and early treatment, with correct choice of treatment method is closely related to the patient′s prognosis.
