Objective:To analyze and evaluate the items of the general module of multidimensional health measurement instruments system for elderly patients with chronic disease (MHIEC-GM)(V1.0) based on classical test theory (CTT) and item response theory (IRT).Methods:A self-administered survey of 2 375 elderly patients with chronic diseases was conducted using the MHIEC-GM(V1.0) scale. The quality of items was analyzed using the variability method, correlation coefficient method, factor analysis method, and Cronbach's α coefficient method based on CTT. The difficulty coefficient, differentiation coefficient, and information content of items were analyzed using the IRT analysis software MULTILOG 7.03.Results:The CTT results showed that the standard deviations of all nine items were greater than 0.9. The results of the correlation coefficient method, the factor analysis method and the Cronbach′s α coefficient method showed that except for the GMI9 item, the correlation coefficients between the other items and the total scale were all greater than 0.5, and the factor loads were all greater than 0.5, and the Cronbach′s α coefficients after the deletion of the items were all less than 0.763. Based on the results of the four analysis methods, except for the GMI9 item, all the other items had good characteristics. The IRT results showed that the information contents of all items were >0.333 (5/15) except for the GMI4, GMI6, and GMI8, and the differentiation coefficient of each item was 1.44. The items that difficulty coefficient met the [-4, 4] inclusion criteria were the GMI2, GMI3, GMI5, GMI7 and GMI9, showing a monotonically increasing trend with increasing difficulty level. The items of GMI1, GMI4, GMI6, and GMI8 needed further improvement.Conclusion:Most of items of the MHIEC-GM(V1.0) scale have good psychometric properties, but some items need to be further revised and validated according to the characteristics of chronic diseases in the elderly.

Objective:To investigate the clinical features and risk factors of multiple organ dysfunction syndrome (MODS) caused by wasp sting.Methods:A retrospective cohort study was conducted to collect the general data of wasp sting patients who had a clear history of wasp sting disease and clinical manifestations from June 2016 to December 2020 and were first diagnosed as wasp sting in hospital. Patients with hematological diseases, malignant tumors, severe liver and kidney dysfunction, cardiac insufficiency, and patients who had received hormone therapy before admission were excluded. Patients who were unable to obtain effective laboratory results due to hemolysis or other reasons within 48 h of admission were also excluded. The white blood cell count (WBC), neutrophil count (NEU), lymphocyte count (LYM), hemoglobin count (HB), myoglobin (Mb/MYO), activated partial thromboplastin time (APTT), albumin (ALB), K, Na, and Cl of the blood samples collected within 48 h after admission were recorded. Patients were divided into the MODS group and non-MODS group according to whether MODS occurred during hospitalization. Uni- and multivariate analysis were used to analyze the factors affecting the occurrence of MODS in wasp sting patients during hospitalization, and the receiver operating characteristic (ROC) curve was plotted to evaluate the predictive effect of myoglobin level on the occurrence of MODS in wasp sting patients during hospitalization.Results:Mb, WBC, NEU, APTT and serum potassium in the MODS group [3890.00 (1416.90-4057.00) ng/mL, (21.99 ± 8.18) × 10 9/L, (19.61 ± 7.33)× 10 9/L, (93.75 ± 45.77) s, and (4.99 ± 0.95) mmol/L] were significantly higher than those in the non-MODS group [73.50 (34.30-264.20) ng/mL, (13.40 ± 4.14)× 10 9/L, (11.18±4.73)× 10 9/L, (37.00 ± 17.16) s, and (4.05 ± 0.56) mmol/L] (all P < 0.05); blood chlorine and ALB [(101.50 (98.25-105.00) mmol/L and (35.36 ± 6.44) g/L)] were significantly lower than those in the non-MODS group [(105.00 (103.00-107.00) mmol/L and (40.71 ± 5.48) g/L)] (all P < 0.05). Multivariate logistic regression analysis showed that NEU ( OR = 0.729, 95% CI: 0.542~0.981), Mb ( OR = 0.999, 95% CI: 0.998~1.000), and APTT ( OR = 0.951, 95% CI: 0.921~0.982) were independent risk factors for MODS in wasp sting patients. ROC curve analysis showed that NEU, Mb and APTT could be used to evaluate the occurrence of MODS in wasp sting patients. Among them, Mb had the highest predictive value (AUC = 0.950, 95 % CI: 0.891~0.982). The optimal cutoff value of Mb for predicting the occurrence of MODS in wasp sting patients was 515.30 ng/mL, and the corresponding sensitivity and specificity were 90.62% and 87.23%, respectively. Conclusion:Mb is an independent risk factor for MODS in wasp sting patients, which can be used as a good predictor of MODS in wasp sting patients.

Objective:To investigate the relationship between Helicobacter pylori(Hp)infections in Parkinson's disease(PD)patients at high altitude and peripheral inflammatory markers.Methods:In this prospective study, 120 PD patients in Qinghai Province(altitude: 2260 m)were enrolled and evaluated using PD motor symptom scales and a non-motor symptom scale.The 13C-Urea breath test was used to detect Hp, and patients were divided into an Hp infection group and a non-Hp infection group based on test results.The levels of high-sensitivity C-reactive protein(hs-CRP), white blood cell counts and ratios, serum interleukin-6(IL-6), and tumor necrosis factor-α(TNF-α)were measured. Results:The incidence of Hp infections in PD patients was 56.67%(68/120).The scores of Unified Parkinson's Disease Rating Scale(UPDRS)-Ⅲ, UPDRS-Ⅳ, total UPDRS, Hoehn-Yahr(H-Y)score, constipation scoring system(CSS)and Leeds dyspepsia questionnaire(LDQ)in the Hp infection group were higher than those in the non-Hp infection group, while the mini-mental state examination(MMSE)score was lower in the non-Hp infection group(all P<0.05).The neutrophil count, neutrophil-to-lymphocyte ratio(NLR), monocyte-to-lymphocyte ratio(MLR), serum IL-6 and TNF-α in the Hp-infection group were elevated compared with the non-Hp infection group(all P<0.05).Multivariate Logistic regression analysis showed that IL-6, TNF-α, NLR and H-Y score were independent risk factors for Hp infections in PD patients( OR=1.103, 1.188, 3.320, 4.593, respectively, all P<0.05).Correlation analysis showed that IL-6, TNF-α and NLR had positive correlations with UPDRS-Ⅲ( r=0.676, 0.644, 0.488, respectively), UPDRS-Ⅳ( r=0.679, 0.660, 0.430, respectively), UPDRS-total score( r=0.391, 0.448, 0.319, respectively), H-Y( r=0.610, 0.750, 0.460, respectively), CSS( r=0.529, 0.366, 0.212, respectively)and LDQ( r=0.581, 0.440, 0.263, respectively), but were negatively correlated with MMSE score( r=-0.617, -0.596, -0.321, respectively)(all P<0.05). Conclusions:Peripheral inflammation caused by Hp infections may be involved in the occurrence and development of Parkinson's disease at high altitude and serum IL-6, TNF-α and NLR could serve as indicators to evaluate PD patients with Hp infections.

Anastomotic leakage is one of the most serious complications following colorectal surgery. Occurrence of anastomotic leakage is concealed and numerous risk factors might relate to anastomotic leakage, which greatly affect the postoperative outcomes and life quality of patients. Therefore, it is necessary to recognize risk factors to predict anastomotic leakage in advance and adopt available treatments to reduce the incidence. This review summarized the risk factors of postoperative anastomotic leakage base on two aspects, and so on. Perioperative related factors and biological markers, aiming to provide a theory for predicting anastomotic leakage then improving the treatment outcomes of colorectal cancer patients .

Gut microbiota plays an important role in the development of colorectal cancer, such as Fusobacterium Nucleatum, Peptostreptococcus and Streptococcus thermophilus. At present, Surgery is the mainly treatment strategy of colorectal cancer patients, supplemented by postoperative radiotherapy and chemotherapy. The influence of gut microbiota on colorectal cancer is not limited to the tumor itself. After tumor resection, gut microbiota is still in a state of disorder, which will affect the short-term and long-term prognosis of patients. Therefore, understanding the relationship between gut microbiota and prognosis of colorectal cancer is helpful to improve the prognosis of patients and reduce postoperative complications. In this review, the author will summarize the influence of gut microbiota on short-term and long-term prognosis of colorectal cancer patients.

Objective:To observe the body fluid and cellular immune function of children with cerebral palsy (CP) in the plateau area, as well as the exchanges of these factors during the comprehensive rehabilitation treatment.Methods:A total number of 144 children admitted to Xining Hospital of Traditional Chinese Medicine from June 2018 to October 2019 were selected as the CP group for comprehensive rehabilitation treatment (consecutive courses). The peripheral blood immunoglobulin/complement (IgA, IgG, lgM, C3, C4) level, T lymphocyte subsets (CD3+, CD4+, CD8+, CD4+/CD8+) and neuron-specific enolase (NSE) content was examined in the clinical specimens before and after treatment by using the immunoturbidimetry, flow cytometry, electrochemiluminescence analysis according to the Gross Motor Function Classification System (GMFCS) and Gross Motor Function Test Scale (GMFM-88). Children were divided as the different degrees to evaluate the rehabilitation efficacy. A total number of 50 healthy children taken a health check/physical examinations during the same period were considered as the control group. For statistical Analysis, the χ2 test and independent sample t test were performed. Results:The levels of humoral immune IgG, IgA, IgM, C3 and C4 in CP Group [(6.42±1.05), (0.64±0.13), (0.89±0.13), (0.80±0.08), (0.17±0.03) g/L, respectively] in CP groups′ children were lower than those in the control group [(10.25±0.62), (1.04±0.06), (1.06±0.17), (1.04±0.04), (0.27±0.04) g/L, respectively]. The humoral immune IgG and IgA levels [severe (5.40±0.69) and (0.55±0.09)g/L, moderate (6.63±0.30) and (0.66±0.14)g/L, mild (7.57±0.63) and (0.74±0.09)g/L, P<0.05] were also related to the children with CP of different GMFCS grades. Moreover, the level of T lymphocyte subsets (CD3+,CD4+,CD8+,CD4+/CD8+) in the CP group were not statistically different to that in the control groups children. Receiving the rehabilitation treatment, the levels of serum humoral IgG and IgA in CP Group (7.69±1.14) and (0.79±0.17) g/L were significantly enhanced; whereas the serum NSE (12.82±2.49) μg/L was lower than that before treatment (18.57±3.08) μg/L, and the total score of GMFM-88 (121.35±26.51) was higher than that before treatment (101.04±27.62). The differences were statistically significant ( P<0.05). IgM, C3, C4 and T lymphocyte subsets (CD3+, CD4+, CD8+, CD4+/CD8+) had no significant difference compared with those before treatment ( P>0.05). Conclusions:Children with CP at high altitude have abnormal humoral immune function. IgG and IgA may be related to the severity of CP and neuronal damage. Comprehensive rehabilitation can not only improve the motor function of children with CP, relieve neuronal damage, but also enhance their humoral immunity status.

Objective:To explore the changes of serum neuron-specific enolase (NSE) and myelin basic protein (MBP) in children with cerebral palsy at high altitude during comprehensive rehabilitation and their clinical significance.Methods:A clinical randomized controlled study design was used to select 144 children with cerebral palsy who were diagnosed and treated in the Rehabilitation Center of Xining Traditional Chinese Medicine Hospital of Qinghai Province from June 2018 to October 2019, including 83 males and 61 females, aged 3-5 years old. According to the order of admission, the random number table was used to divide into a conventional treatment group ( n=72, 40 males and 32 females) and a comprehensive treatment group ( n=72, 43 males and 29 females). The conventional treatment group was treated with conventional rehabilitation. The comprehensive treatment group was treated with monosialotetrahexose ganglioside sodium on the basis of conventional rehabilitation. In addition, 30 healthy children aged 3-5 years, 16 males and 14 females, were selected as the control group during the physical examination of the Pediatrics Department of Xining Hospital of Traditional Chinese Medicine, Qinghai Province. The serum levels of NSE and MBP in each group were detected, and the children′s GMFM-88 scores were evaluated before and after treatment. The SPSS19.0 software was used for statistical analysis, the count data was tested by χ 2. Results:The serum NSE and MBP levels of the control group were (5.96±0.80), (0.71±0.15) μg/L. Before treatment, the serum NSE and MBP levels of children with severe, moderate, and mild cerebral palsy were [(21.63±1.92), (3.63±0.49) μg/L], [(17.86±1.43) μg/L, (2.21±0.07) μg/L] and [(15.14±0.95), (1.76±0.30) μg/L], respectively. After treatment, the serum NSE and MBP levels of the conventional treatment group and the comprehensive treatment group were [(13.54±2.41), (2.07±0.85) μg/L] and [(12.09±2.37), (1.81±0.69) μg/L], respectively, and the GMFM-88 score was (116.75±27.41) points and (125.94±24.93) points. The levels of NSE and MBP in the serum of children with cerebral palsy were significantly higher than those of normal children in the control group, and their levels increased with the degree of disease, and the corresponding gross motor function scores were lower. After treatment, the GMFM-88 scale assessment scores of the two groups of children were significantly improved ( t values were 310.97 and 70.86, P values were both<0.05), and serum NSE and MBP levels decreased to varying degrees compared with before treatment. The decline in the comprehensive treatment group was greater than that in the conventional treatment group. Conclusions:Serum NSE and MBP levels in children with cerebral palsy at high altitude are significantly higher than those in healthy children, and their levels are closely related to the degree of impairment and GMFM-88 scores in children with cerebral palsy. Dynamic monitoring of changes in NSE and MBP levels may be responsible for the condition and treatment effects of children with cerebral palsy judgments based.

Gastric cancer is a malignant tumor with high morbidity and mortality, which is a serious threat to human life and health. At present, the diagnosis and course monitoring of gastric cancer mainly rely on gastroscopic biopsy and CT, but their invasiveness and delay limit their clinical value. Gastric cancer patients urgently need a real-time, accurate, non-invasive diagnosis and course monitoring method. Circulating tumor DNA(ctDNA) is single or double stranded DNA released into body fluid by tumor cells, which contains the same genetic mutations as the original tumor cells. It is also one of the newly emerged biological markers. With the emergence and development of next-generation sequencing(NGS) technology, the sensitivity and specificity of ctDNA detection continue to increase, and it is gradually becoming a new choice for tumor diagnosis and disease course monitoring. In this paper, the current application of the next-generation sequencing technology detecting ctDNA in diagnosis and treatment of gastric cancer was discussed.
