Objective To investigate the changes of inflammation levels in patients with impaired glucose tolerance(IGT) and the clinical significance.Methods A total of 30 IGT patients(IGT group) and 30 type 2 diabetes (T2DM) patients (T2DM group) were enrolled in current study.Meanwhile,30 health people were selected as control group (NGT group).The concentration of fasting plasma glucose (FPG),insulin resistance index (HOMA-IR),glycosylated hemoglobin (HbA1c),high-sensitivity C-reactive protein (hsCRP),cystatin C(Cys C) and fibrinogen(FIB) were measured.Results The levels of FPG,2 h glucose(2 h PG),HOMA-IR and HbA1c in three groups were significant (F =8.805,14.403,7.389,10.246 ; P ＜ 0.05).The levels of CRP,Cys C and FIB in three group were also significant (F =6.766,4.733,11.683 ;P ＜ 0.05).The levels of CRP,Cys C,FIB in IGT were (1.12 ±0.22) mg/L,(0.23 ±0.10) mg/L,(0.93 ±0.18) mg/L,higher than that in NGT group((0.70 ±0.16) mg/L,(6.02 ±0.49) g/L and (4.36 ±0.30) g/L).Meanwhile,the levels of CRP,Cys C and FIB in T2DM were significantly higher than of NGT(P ＜ 0.05).Single factor correlation analysis showed that there was positive associationship between hs-CRP,Cys C and FIB with 2 h PG,HbA1 c and HOMA-IR(P ＜ 0.05).Conclusion Endothelial dysfunction is seen in prediabetes stage,which plays an important role in the occurrence and development of vascular disease in impaired glucose regulation and diabetic patients.

Objective To explore the clinico-pathological features and outcomes of primary focal segmental glomerular sclerosis with IgM deposition.Methods One hundred and two patients with primary focal segmental glomemlar sclerosis (pFSGS) in Hangzhou hospital of traditional Chinese medicine between 1996 and 2012 were retrospectively studied.The patients were divided into IgM deposition group (n =66) with IgM deposition in glomeruli and none-IgM deposition group (n =36) without IgM deposition.Baseline and clinical characteristics of all FSGS patients were assessed and outcomes were reviewed.The survival rates of the patients were analyzed using the Kaplan-Meier method.Results (1) There were not difference in age,sex ratio,incidence of microscopic hematuria,hypertension,renal insufficiency,eGFR,Ccr and Scr between two groups.However,proteinuria,incidence of nephrotic syndrome,urine microalbumin,urine NAG,serum cholesterol,serum high-density lipoprotein,and serum IgM in IgM deposition group were significantly higher than those in none-IgM deposition group (P ＜ 0.05),serum albumin and serum IgA in IgM deposition group were significantly lower than those in none-IgM deposition group (P ＜ 0.05).(2) The IgM deposition group had a significantly higher incidence of glomerular deposition of IgA,IgG,C3,C1q and fibrinogen than none-IgM deposition group (P ＜ 0.05).The score of mesangial matrix proliferation in the IgM deposition group was lower than that in none-IgM deposition group (P ＜ 0.05).(3) fifty-four patients (35 patients in IgM deposition group and 19 patients in none-IgM deposition group) were followed-up for a median of 64.6 (22.8,103.8) months.Progression to renal failure was observed in 5 patients of IgM deposition group and none in none-IgM deposition group.Compared with the none-IgM deposition,the survival rates in the IgM deposition group were statistically lower (P ＜ 0.05).Conclusions PFSGS patients with IgM deposition were severer in proteinuria,higher incidence of IgA,IgG,C3,C1q and fibrinogen deposition in glomeruli and worse outcome than those without IgM deposition.

Objective To assess the validity of PKH26 dye for labeling the bone marrow mesenchymal stem cells (BMSCs) and the feasibility of this method for tracing the seed cells of tissue engineering nerve in vivo. Methods BMSCs isolated from Wistar rat's bone marrow were labeled with the PKH26 dye, the marked validity was observed by the fluorescence microscopy and flow cytometer, the cellular vitality was de-tected by MTT, the differentiated abilities were tested by in vitro osteablastic and lipoblastic differentiation. After that, the labelld cells were micro-injected into the acellular nerve grafts(ANG) to build compound grafts and cultured for 3,5,7,14 days in vitro, then frozen sections were made respectively to observe the survival and migration of the implanted cells in ANG. Simultaneously, these compound grafts were used to bridge the 1.5 cm sciatic nerve defects of the Wistar rats, 1,4,6,8 weeks postoperation, the grafts were taken out and frozen section were made in order to observe the survival of the implanted stem cells in vivo inside the ANG. Results PKH26 dye was good for labelling the BMSCs, marked validity was higher than 95%. The cellular vitality and differentiated abilities were not affected compared with the unlabelled cells. Further more, BMSCs could adhere to the ANG, and suvive,magrate in vitro. In vivo, BMSCs was able to survive at least 8 weeks in the nerve regenerative microenvironment. Conclusion PKH26 dye could label the BMSCs effectively, and it's suitable for in vivo seed cells tracing in tissue engineering nerve model.

Objective To analyze five kinds of allogenic acellular peripheral nerve by different meth-ods and try to establish a standard method for preparing nerve materials. Methods Five kinds of nerve ma-terial prepared by different chemical extractions according to nowaday articles were examined by HE staining. Irmnunohistochemistry and protein ratio was studied by allogenic nerves by virtue of Kjeldahl method in order to know the efficiency of these methods in removal of SCs axons and integrality of the basilar membrane. Results Myelin sheath and cytoblast in group 2 that nerves were extracted by Triton X-100 and Sodium de-oxycholate consecutively twice were completely removed, which was well demonstrated in HE staining. Per-ineurium in red staining were arranged wave-like longitudinally, axons and myelin sheath were replaced by column-like spacing. Col I staining were positive in all groups, structure of basilar membrane became loose slightly in the first and second group, and the structure of the other groups were relatively regular. Group 1 and 2 were negative in S-100 staining. There was no difference between group 2 and group 1,3,4 and 5 in sheath removal demonstrated by TEM. Protein ratio in group 2 was the lowest in the measurement with Kjel-dahl method. Conclusion The method used in group 2 that nerves were extracted by Triton X-100 and Sodium deoxycholate consecutively twice was the best in allogenic acellular peripheral nerve preparations.

Objective:To explore the therapeutic law of moxibustion in Professor Zhou Meisheng's medical manuscripts for epidemic hemorrhagic fever (EHF) based on data mining and knowledge map technology.Methods:The manuscript data of Professor Zhou Meisheng's moxibustion treatment of EHFwere collected from Infectious Diseases Department of Dangshan County People's Hospital from December 16, 1985 to December 25, 1987. Graphpad Grism 8.0 software was used for descriptive analysis. PHP 5.4 program code was used for association rule analysis. SPSS Statistics 26.0 was used for clustering analysis. Neo4j Community 3.5.25 database was used to analyze the syndrome-weight graph.Results:205 prescriptions were included. There were 21 symptoms with frequency>40, in which the frequency of aversion to cold, fever, rash and irritability was 100%. The main types of moxibustion methods used in the treatment included moxibustion frame fumigation moxibustion, Wanying acupoint moxibustion pen moxibustion, and fire needle instead of moxibustion. There were 29 acupoints with a frequency of >25, including Zhongwan (CV12), Shenshu (BL23) and Mingmen (DU4), etc. Association rules showed that Sanyinjiao (SP6)-Zhongwan (CV12)-Feishu (BL13)-Shenshu (BL23)-Zhiyang (DU9) had the highest correlation. Six effective clustering combinations of moxibustion for EHF were summarized by clustering analysis. The weight graph can obtained the first 30 relationships with high correlation of target syndromes.Conclusions:Professor Zhou applied the idea of "moxibustion for heat syndrome" to the treatment of EHF, and took the method of "acupoint selection according to symptoms" as the main acupoint selection idea for moxibustion treatment of EHF. In clinical practice, moxibustion combined with auxiliary operation of TCM is often used to treat EHF, which can achieve good results.

Objective:To investigate the effect of situational simulation drill in nurses training on prevention and treatment of venous thromboembolism (VTE).Methods:Totally 120 nurses in 1-3 years from a tertiary general hospital were selected to participate in the training for prevention and treatment of venous thromboembolism. They were divided into intervention group and control group according to the number of single and double packet ward. A total of 62 nurses in the single wards were selected as the intervention group, and a total of 58 nurses in the double wards were selected as the control group.

Objective:To explore the correlation between socioeconomic status (SES) and diabetic kidney disease (DKD) in patients with type 2 diabetes (T2D).Methods:A total of 276 T2D patients admitted to the Second Affiliated Hospital of Nanjing Medical University from January to June 2020 were enrolled in this cross-sectional study. The estimated glomerular filtration rate (eGFR) was calculated according to the urinary albumin/creatinine ratio (UACR) and the chronic kidney disease epidemiology collaboration equation(CKD-EPI formula) based on serum creatinine. The patients were divided into simple T2D group (184 cases) and DKD group (92 cases). Collect demographic and laboratory examination data, record education, income and occupation, and calculate standardized SES scores. According to SES scores, subjects were divided in three levels: SES≤9, SES≥10-≤12, and SES≥13. Student's t test was used for comparison of measurement data with normal distribution between two groups, and one-way ANOVA was used for comparison between multiple groups. Non-normal distribution was represented by M( Q1, Q3), and rank-sum test was used for comparison between groups. Counting data were expressed as frequency or percentage, and chi-square test was used for comparison between groups. Bofferoni test was further used for pairwise comparison of indicators with statistical significance among multiple groups. Spearman correlation analysis was used to analyze the correlation between variables. The risk factors were analyzed by binary Logistic regression. Results:The age of the subjects was (53.37±10.68) years, men accounted for 55.8% (154/276), the duration of diabetes was 60.00 (12.00, 134.00) months, and eGFR was (97.56±21.15) mL/(min·1.73 m 2).

Prevalence of hypertension, systolic blood pressure, diastolic blood pressure, triglycerides, serum uric acid, serum creatinine, UACR in DKD group were higher than those in simple T2D group. Serum albumin, high density lipoprotein cholesterol and eGFR in DKD group were lower than those in simple T2D group. There was significant difference between the two groups ( χ2=7.95, t values were 4.87, 4.40, 3.04, 3.26, 2.30, 3.22, 5.56, 5.95, Z=13.07, P values were 0.005, <0.001, <0.001, 0.003, 0.001, 0.022, 0.001, <0.001, <0.001, and <0.001, respectively). The number of males in the three groups with SES ≥13 group, SES≥10-≤12 group, SES ≤9 group were 61 (81.3%, 61/75), 55 (59.8%, 55/92), 38 (34.9%, 38/109), respectively. The number of cases with smoking history were 42 (56.0%, 42/75), 41 (44.6%, 41/92), 35 (32.1%, 35/109), respectively. The number of cases with drinking history were 38 (50.7%, 38/75), 32 (34.8%, 32/92), 26 (23.9%, 26/109), respectively. The ages were (47.77±10.76), (52.76±11.22), (57.74±7.96) years old, respectively. Body mass index (BMI) were (26.17±3.87), (24.96±3.93), (24.27±4.89) kg/m 2, respectively. High density lipoprotein cholesterol (HDL) were (1.03±1.03), (1.16±0.41), (1.21±0.32) mmol/L, respectively. Serum uric acid were (336.56±82.05), (293.78±94.78), (307.99±96.53) μmol/L, respectively. EGFR were (105.03±19.72), (99.77±19.44), (90.57±21.49) mL/(min·1.73 m 2),respectively.The difference between groups were statistically significant (χ 2=39.79, 10.55, 14.08, F=22.69, 4.03, 6.20, 4.53, 12.02, P values were <0.001, 0.005, 0.001, <0.001, 0.019, 0.002, 0.012, and <0.001, respectively). Pairwise comparison shows that male and eGFR in SES ≤9 group were lower than those in SES ≥13 group and SES≥10-≤12 group, age in SES ≤9 group was higher than that in SES ≥13 group and SES≥10-≤12 group. The difference was statistically significant (all P<0.05). Smoking history, alcohol history and BMI in SES ≤9 group were lower than those in SES ≥13 group, and the high density lipoprotein cholesterol in SES ≤9 were higher than that in SES ≥13 group. The difference was statistically significant (all P<0.05). Male, alcohol history and serum uric acid in SES≥10-≤12 group were lower than those in SES ≥13 group, and age and high density lipoprotein cholesterol in SES≥10-≤12 group were higher than those in SES ≥13 group. The difference was statistically significant (all P<0.05). Spearman correlation analysis showed that SES in T2D was positively correlated with male, smoking history, alcohol history, BMI, serum uric acid and eGFR ( r values were 0.38, 0.20, 0.24, 0.16, 0.13 and 0.31, P values were <0.001, 0.001, <0.001, 0.008, 0.028, and <0.001, respectively), and negatively correlated with age, high density lipoprotein cholesterol and UACR ( r values were -0.35, -0.24 and -0.14, P values were <0.001, <0.001, and 0.017, respectively). Logistic regression analysis showed that SES (OR=2.71,95% CI:1.10-6.68, P=0.031) was associated with T2DM combined with DKD. The risk of developing DKD increased when the SES was ≤9. Conclusion:The SES in patients with type 2 diabetes is closely related to DKD. Low SES may be a new risk factor for DKD in type 2 diabetic patients.
