Objective To study the relationship between serum insulin-like growth factor-1 (IGF-1) and resistin levels and osteoporosis in patients with type 2 diabetes mellitus (T2DM). Methods This study was conducted on 306 T2DM patients admitted to Baoding No.2 Central Hospital from January 2018 to January 2022. According to the detection results of bone mineral density, the patients were divided into osteoporosis group (T≤-2.5) and non-osteoporosis group (T>-2.5). The differences in IGF-1, resistin and bone mineral density were compared between the two groups. Pearson correlation analysis was used to analyze the correlation between serum IGF-1 and resistin levels and bone mineral density in patients with osteoporosis. Receiver operating characteristic (ROC) curve was applied to evaluate the application value of IGF-1 and resistin in predicting osteoporosis in patients with T2DM. Patients with T2DM complicated with osteoporosis were followed up for 2 years, and the occurrence of fractures was assessed. After univariate analysis, multivariate logistic regression analysis was applied to screen the risk factors for fractures in T2DM patients with osteoporosis. Results The incidence rate of osteoporosis in patients with T2DM was 53.59% (164/306). The IGF-1 level and bone mineral density level in the osteoporosis group were lower than those in the non-osteoporosis group, while the level of resistin was higher than that in the non-osteoporosis group (P<0.05). Serum IGF-1 in patients with osteoporosis was positively correlated with bone mineral density, and serum resistin was negatively correlated with bone mineral density (P<0.05). The AUC, sensitivity and specificity of combination of IGF-1 and resistin in predicting osteoporosis were 0.888, 82.93% and 62.68% respectively, which were all higher than those of single factor prediction (P<0.05). The 164 T2DM patients with osteoporosis were followed up for two years, and 15 patients developed fragility fractures, with the incidence of fracture of 9.15% (15/164). Multivariate analysis showed that hypoproteinemia, high-intensity exercise, lack of nutritional management, low IGF-1, and high resistin were risk factors for fractures in patients with T2DM complicated with osteoporosis (P<0.05). Conclusion For patients with T2DM, the incidence rates of osteoporosis and fractures are high. The levels of IGF-1 and resistin are closely related to bone mineral density, which can be combined to predict osteoporosis. Hypoproteinemia, high-intensity exercise, lack of nutritional management, low IGF-1 and high resistin are risk factors for fractures in T2DM patients with osteoporosis. It is necessary to carry out targeted preventive measures in clinical practice to reduce the incidence rate of fractures.

Objective:To investigate the predictive value of differential distribution of peripheral lymphocyte subsets before and after the first 131I treatment on the therapeutic response to 131I treatment in patients with papillary thyroid cancer (PTC). Methods:A retrospective study was conducted on 46 PTC patients (16 males, 30 females, age 20-77 years) who underwent total thyroidectomy and received 131I treatment between January 2021 and August 2021 in First Hospital of Shanxi Medical University. Peripheral blood lymphocyte subsets (T, B, CD4 + T, CD8 + T, natural killer (NK), helper T (Th)1, Th2, Th17, and regulatory T (Treg) cells) were measured 1-2 d before and 30 d after 131I treatment. Based on serological and imaging evidence, therapeutic response at 6-12 months post- 131I therapy was categorized as either excellent response (ER) or non-excellent response (NER). Differences of preablative stimulated thyroglobulin (psTg) and clinical baseline characteristics between two groups were assessed by using independent-sample t test, paired t test, or Mann-Whitney U test. Predictive value of lymphocyte subsets before and after 131I treatment for therapeutic response was assessed through logistic regression analysis, ROC curve analysis, and decision curve analysis (DCA). Results:In ER group ( n=33) and NER group ( n=13), most lymphocyte subsets showed different degrees of reduction 30 d after 131I treatment compared to before 131I treatment, such as T, B, CD4 + T and Th1 cells in ER group, as well as T, B, CD4 + T, Th1, Th2, Th17, and Treg cells in NER group ( t values: 2.41-9.57, all P<0.05). Before 131I treatment, NER group had significantly higher levels of psTg, Th2, Th17, and Treg cells compared to the ER group ( t values: from -3.32 to -2.48, U=29.00, all P<0.05). After 131I treatment, most of lymphocyte subsets in NER group (T, B, CD4 + T, CD8 + T, Th1 and Treg cells) showed higher trend than those in ER group but without statistical significances ( t values: from -1.12 to -0.06, all P>0.05). Th2 cells before 131I treatment (odds ratio ( OR)=25.00, 95% CI: 1.36-459.10, P=0.030) was identified as a risk factor for NER. ROC curve analysis indicated that AUCs of psTg and Th2 cells for predicting therapeutic response were 0.932 and 0.790, respectively, which was 0.958 for the combined psTg and Th2 cells. DCA showed that within the threshold probability range of 10%-60%, the curves for psTg, Th2 cells, and the combined psTg and Th2 cells were all higher than the extreme curve, suggesting good effect. Conclusions:Most lymphocyte subsets decrease to varying degrees, and NER group shows a significant decrease 30 d after 131I treatment. Th2 cells may be a risk factor for poor response to 131I treatment, providing a certain value in predicting the therapeutic response to 131I treatment.

Objective:To investigate the protective effect of quercetin(QUE)on acute lung injury(ALI)rats with sepsis.Methods:Sixty male SD rats were randomly divided into 6 groups(n=10):Sham operation group(Sham),model group(CLP),QUE 25 mg/kg group,QUE 50 mg/kg group,QUE 100 mg/kg group and positive drug dexamethasone(DEX)group.Rats in each group were continuously treated for 7 days,and the survival rate was calculated;HE staining and lung wet-to-dry weight ratio(W/D)were used to evaluate the severity of lung injury;TUNEL staining was used to detect lung tissue apoptosis;levels of inflammatory factors,SOD and MDA were detected by the kits;Western blot was used to detect expressions of apoptosis-related proteins and phosphoryla-tion levels of PTEN,β-catenin,protein kinase B(AKT)and glycogen synthase kinase-3β(GSK-3β)in rat lung tissue.Results:Com-pared with CLP group,after QUE 50 mg/kg and 100 mg/kg treatment,survival rate of rats was significantly increased(P<0.05),the degree of inflammatory cell infiltration in lung tissue was reduced,lung injury score and W/D were reduced(P<0.05),apoptosis rate of lung tissue cells and expressions of apoptosis-related proteins were significantly decreased(P<0.05),levels of inflammatory factors were decreased(P<0.05),while the antioxidant capacity was enhanced(P<0.05),phosphorylation levels of PTEN and β-catenin were decreased,while phosphorylation levels of AKT and GSK-3β were increased(P<0.05).Conclusion:QUE protects rats from ALI with sepsis by inhibiting apoptosis,reducing inflammation and antioxidance,which mechanism may be related to PTEN/β-catenin and AKT/GSK-3β pathways.

Objective To investigate the correlation of IL-6-572GC mutation with the incidence and severity of CHD in the Han elderly in Henan Province.Methods A total of 446 elderly CHD pa-tients of Han majority in Henan Province who were admitted to Department of Cardiovascular Diseases of our hospital from January 2020 to December 2022 were enrolled as the study group,and 218 healthy elderly patients taking physical examination in the same period were selected as the control group.The genotypes of IL-6-174GC,IL-6-572GC and IL-6-597GA were detected in the two groups.Logistic regression analysis was used to analyze the relationship between IL-6-572G/C gene polymorphism and CHD in the elderly,as well as the correlation between IL-6-572GC genotype and the severity of CHD.Results Larger proportions of hypertension and diabetes and higher LDL-C level,but lower HDL-C level were observed in the study group than the control group(P＜0.05,P＜0.01).There were three genotypes at IL-6-174GC locus(GG,GC and CC),three genotypes at IL-6-572GC locus(GG,GC and CC),and three genotypes at IL-6-597GA locus(GG,GA and AA).There were no significant differences in the genotype fre-quencies of IL-6-174GC and IL-6-597GA between the two groups(P＞0.05),but there was a sig-nificant difference in the genotype frequency of IL-6-572GC(P＜0.01)and the genotype frequen-cy of GG was significantly lower in the study group than the control group(33.18％vs 46.82％,P＜0.01).Logistic regression analysis showed that IL-6-572GC(OR=1.534,95％CI:1.180-1.995),hypertension(OR=1.442,95％CI:1.033-1.957),diabetes(OR=1.610,95％CI:1.083-2.391),HDL-C(OR=0.467,95％CI:0.266-0.818)and LDL-C(OR=2.004,95％CI:1.104-3.636)were all influencing factors of CHD(P＜0.05,P＜0.01).At IL-6-572GC locus,the inci-dence of single branch lesions was higher in the carriers of GG genotype than those of GC and CC genotypes,and the incidence of 3-branch lesions was lower than that of CC genotype(P＜0.05).Conclusion The mutation of IL-6-572GC gene is correlated with the incidence and severity of CHD in the elderly Henan Han people,and its mutation also increases the risk and severity of the disease.

OBJECTIVES: To evaluate curative effects of coronavirus disease 2019 (COVID-19) patients by the transfusion of other convalescent plasma. METHODS: Retrospective analysis of the clinical data of 18 patients with severe and critical COVID-19, who were hospitalized in the ICU of Xianghu Branch of the First Affiliated Hospital of Nanchang University from February 1 to March 15, 2020. Patients were subdivided into an experimental group (=6, who had transfused the plasma) and an observation group (=12, who had no plasma transfusion). Basic clinical data and prognosis indexes of these two groups were compared. Moreover, for the experimental group, the dynamic changes of blood oxygen saturation before and after the transfusion, the changes of lymphocyte absolute value 48 hours after the transfusion, and the detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleic acid were analyzed. RESULTS: There were no significant differences in age, gender, blood type and other basic clinical data between the two groups (all >0.05).There were no significant differences in ventilator machine weaning time, extracorporeal membrane oxygenation (ECMO) weaning time, body temperature recovery to normal time, and hospitalization days between these two groups (all >0.05). For the experimental group, before, during and after the convalescent plasma transfusion, the blood oxygen saturation of all 6 patients at all time (1, 6, 8, 12, 24, 36, and 48 h) was more than 90%, and there was no significant fluctuation. There were 3 patients whose absolute value of lymphocyte was increased 48 hours after the transfusion, and the remaining was decreased. There were 5 patients whose SARS-CoV-2 nucleic acid detection turned negative 48 hours after the transfusion, accounting for 83.3%. CONCLUSIONS Transfusion of convalescent plasma will not affect outcomesof COVID-19 patients, which can neutralize SARS-CoV-2 in patients and reduce the loading capacity of SARS-CoV-2.

Objective:To investigate the epidemiological and pathogenic characteristics of a mumps outbreak in a primary school in Xining, Qinghai province.Methods:The epidemiological investigation was carried out to analyze the epidemiological distribution of mumps cases in the outbreak. Serum and throat swab samples were collected from 9 suspected mumps cases for laboratory testing. The throat swab samples detected positive for nucleic acid of mumps virus were subjected to virus isolation. Then the SH gene was amplified by RT-PCR for positive virus isolates, and the genotypes of mumps virus were identified and gene characteristics were analyzed.Results:A total of 13 cases were reported in this outbreak. The age of cases was mainly 7-11 years old, and the cases were mainly concentrated at 8 years old (69.23%. 9/13). The male to female ratio is 1.6: 1. None of the 13 cases had a history of mumps vaccination. And there was an obvious in-class clustering in this mumps outbreak. Of the 9 suspected mumps cases, 8 were double positive for mumps specific IgM antibody and viral nucleic acid. Two positive mumps virus isolates were obtained and identified by genotyping as F genotype, and the SH gene sequence of the two mumps virus isolates had 100% homology.Conclusions:This outbreak is caused by genotype F mumps virus. MuV immunization activities were recommended to conduct among unvaccinated students in primary and secondary schools.

Objective The aim of this study was to analyze the disease burden of cirrhosis and other chronic liver diseases caused by hepatitis B in China,from 1990 to 2016,and to provide evidence for the development of related strategies.Methods Data were collected from the results of the Global Burden of Disease Study 2016 (GBD2016).We analyzed the current epidemiological patterns by calculating the prevalence,mortality,and disability adjusted life year (DALY) of cirrhosis and other chronic liver diseases,caused by hepatitis B during 1990 and 2016 in China.Results Compared with data from 1990,the number of patients and deaths with cirrhosis and other chronic liver diseases caused by hepatitis B in 2016 increased by 79.6％ and 2.4％,respectively.The prevalence increased by 49.2％,higher (50.3％) in males than that (42.3％) in females.Compared with other age groups,the increase (33.2％) of prevalence appeared the fastest,in the 15-49 age group.In males,the number of deaths and DALYs increased by 13.6％ and 2.2％,respectively.In 2016,the five top provinces on age-standardized DALY rates,appeared as Qinghai (314.6 per 100 000),Guizhou (303.1 per 100 000),Yunnan (262.4 per 100 000),Guangxi Zhuang Autonomous Region (239.6 per 100 000) and Taiwan (227.2 per 100 000).Conclusions From 1990 to 2016,the prevalence rates of hepatitis B related cirrhosis and other chronic liver diseases showed an upward trend,particularly in males and in people aged 15 to 49 years old,in China.However,the disease burden of different provinces was unevenly distributed.Based on our findings,we suggested that strategies that related to prevention and management of hepatitis B caused cirrhosis and other chronic liver diseases should be paid more attention to.

Objective To study the clinical efficacy of sodium cantharidinate and vitamin B6 injection combined with concurrent chemoradiotherapy in treatment of locally advanced nasopharyngeal carcinoma (LA-NPC).Methods 115 patients with LA-NPC in Shanxi Cancer Hospital were randomly assigned to observation group (61 cases) and control group (54 cases) from February 2014 to April 2016.The patients in the observation group were treated with sodium cantharidate and vitamin B6 injection combined with concurrent chemoradiotherapy.The patients in the control group were treated with concurrent chemoradiotherapy.The differences between the two groups were compared in respect of recent curative effect,the quality of life (QOL) and the adverse reactions.Results The recent effective rate was 93.44 ％ (57/61) in the observation group and 79.63 ％ (43/54) in the control group,and there was significant difference between the two groups (x2 =4.818,P =0.049).The improvement rate of QOL was 73.77 ％ (45/61) in the observation group and 53.70 ％ (29/54) in the control group,and there was significant difference between the two groups (x2 =5.028,P =0.032).The incidence rates of oral cavity mucous membrane inflammation,hematology toxicity,pharynx and esophagus adverse reactions,the gastrointestinal tract adverse reactions and skin fibrosis in the observation group were lower than those in the control group,and there were significant differences between the two groups (all P ＜ 0.05).Conclusion The recent effect of sodium cantharidinate and vitamin B6 injection combined with concurrent chemoradiotherapy on the patients with LA-NPC is obvious.The comprehensive treatment can also reduce adverse reactions and improve the QOL.

Objective To evaluate the role of calcium channel in the mechanism of the generation and maintenance of bursting firing of substantia nigra pars compacta (SNc) dopaminergic neurons in rats.Methods Using the patch clamp technique,we observed the firing pattern switching features after adding 10 μmol/L N-methyl-D-aspartic acid (NMDA),compared the changes of whole-calcium current and L-type calcium current with or without NMDA,and analyzed the correlation between the generation of burst firing and L-type calcium channel activation.Results After NMDA treatment,the firing pattern of SNc dopaminergic neurons changed to burst firing,which was compromised by a charastistic high plateau potential and series of action potential on it.The current density of L-type calcium current increased significantly after adding NMDA,which,from (2.86 ±0.26) pA/pF (n =28),significantly increased to (3.75 ± 0.18) pA/pF (n =34 ; t =7.52,P =0.002 8).The high plateau potential was almost abolished with the application of verapamil,a specific antagonist of L-type calcium channel.Consiusion NMDA could induce the firing pattern changed to burst firing in SNc dopaminergic neurons,while L-type calcium channel contributes to the process of generation and maintenance of burst firing.
