Objective To comprehensively evaluate the development capacity of secondary public hospitals and provide hospital decision makers with objective and valid information.Methods By means of non-probability random sampling,13 secondary public hospitals were pinpointed nationwide,from which statistics of hospital development between 2005 to 2009 were collected for factor analysis of development capacity.EPIDATA3.1 and SAS9.2 were used for data input and analysis.Results Key development factors on development capacity of such hospitals are workload,hospital size,human resources and specialties.The hospitals vary in their development capacity factors to tell a difference.Conclusion Such factors as workload,size,staff makeup and specialty competence play a key role in development of such hospitals.

Objective To evaluate the differential diagnostic value of 18F-FDG PET/CT between pancreatic lymphoma (PL) and pancreatic carcinoma (PC).Methods The 18 F-FDG PET-CT data of 16 patients who were pathological diagnosed with PL were retrospectively reviewed and compared with those of 32 consecutive pancreatic cancer patients who were pathologically diagnosed and randomly enrolled.The age,location,diameter and the maximum standard uptake values (SUVmax) of pancreatic lesions,pancreatic ductal dilatation,distal pancreatic atrophy,serum CA19-9 level and extrapancreatic organs involvement were analyzed.Results The 16 patients with PL included 8 men and 8 women,the mean age was (46 ± 17)year,and 11.1％ (1/9) patients had elevated CA19-9.The 32 patients with PC included 15 men and 17 women,the mean age was (61 ± 12)year,and 81.3％ patients had elevated CA19-9.There were no significant differences on gender between the two groups,while the mean age of PL patients was younger than that of PC,elevated CA19-9 was less common than that in PC,and the differences were statistically significant (all P＜0.05).There were 12 cases of diffusive large B cell lymphoma,2 cases of B lymphoblastic lymphoma/leukaemia,1 case of follicular lymphoma and 1 case of dysplastic large T cell lymphoma in 16 PL patients.There was no significant difference on the site of pancreatic lesions between the two groups,but long diameter of PL lesions was larger than that of PC [(6.6 ± 3.3) vs (4.3 ± 1.8) cm,P =0.038].Dilated pancreatic duct and distal parenchyma atrophy in PL were less than those in PC (3/16 vs 17/32,1/16 vs 13/32),and SUVmax of PL lesions was significantly higher than that of PC (12.0 ± 5.5 vs 8.6 ± 3.8),indicating that the differences were statistically significant (all P ＜ 0.05).The cut-off value of SUVmax was 9.95,and Youden's index was 0.406 with the sensitivity and specificity of 68.8％ and 71.9％ for differentiating PL from PC.The incidence of extrapancreatic lesions including bone marrow and kidney and spleen infiltration was significantly more frequent in patients with PL than that in patients with PC(56.3％ vs 6.25％,43.8％ vs 3.1％,50.0％ vs 6.3％),while the incidence of liver metastases was significantly lower than that in PC (12.5％ vs 5.0％),indicating that the differences were statistically significant (all P ＜0.01).There were no significant differences on the incidence of other extrapancreatic lesions.Conclusions PL should be considered in relatively younger patients and manifested as a bulky mass with significant FDG uptake and extrapancreatic involvement of bone,kidney and spleen but without distinct pancreatic ductal dilation or distal parenchymal atrophy or liver metastasis.

Objective To investigate the changes in serum procalcitonin (PCT) in patients with severe pneumonia, and to analyze its value on evaluating the clinical outcome of patients with severe pneumonia. Methods A total of 58 patients with severe pneumonia aged over 18 years, and admitted to intensive care unit (ICU) of Zhuozhou City Hospital of Hebei Province from January 2017 to July 2018 were enrolled. The patients were divided into recovery group (the symptoms and signs of pneumonia disappeared or improved, and the X-ray chest films improved or did not make significant progress) and deterioration group (the symptoms and signs of pneumonia persisted or progressed, while X-ray chest radiography progressed, as well as serious complications such as involvement of other organ functions due to deterioration of pulmonary infection or septic shock) according to the therapeutic outcome. The serum PCT levels at 1, 3, 5, 7, 9 days after severe pneumonia diagnosed were recorded, and procalcitonin clearance rate (PCTc) was calculated. The acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score was estimated within 24 hours when severe pneumonia was diagnosed. Receiver operating characteristic (ROC) curve was drawn, and the area under ROC curve (AUC) was calculated to analyze the value of PCTc on evaluating the clinical outcome of patients with severe pneumonia. Results Among 58 patients, 33 (56.9%) had better outcome after active treatment (recovery group), and 25 (44.1%) had worse condition (deterioration group). There was no significant difference in PCT level at 1 day or 3 days between the recovery group and the deterioration group [μg/L: 5.05 (3.89, 7.61) vs. 5.29 (4.15, 7.46) at 1 day, 4.59 (4.02, 6.90) vs. 5.70 (4.59, 7.28) at 3 days, both P > 0.05]. With the prolongation of treatment time, serum PCT level was gradually decreased in the recovery group, while remained at higher level in the deterioration group, which was significantly lowered at 5, 7, 9 days in the recovery group as compared with that in the deterioration group [μg/L:2.92 (2.09, 3.42) vs. 6.09 (3.24, 7.96) at 5 days, 1.94 (1.50, 2.07) vs. 7.65 (5.60, 10.52) at 7 days, 1.37 (0.91, 1.74) vs. 8.96 (6.09, 10.87) at 9 days, all P < 0.01]. PCTc at 3, 5, 7, 9 days in the recovery group were significantly higher than those in the deterioration group [15.10 (-17.80, 32.10)% vs. -1.53 (-20.80, 11.48)% at 3 days, 47.50 (30.25, 60.34)% vs. 6.25 (-14.58, 29.05)% at 5 days, 76.44 (53.18, 77.92)% vs. -11.20 (-66.75, -1.38)% at 7 days, 80.01 (59.86, 88.27)% vs. -38.15 (-99.38, -2.81)% at 9 days, all P < 0.05]. ROC curve analysis showed that PCTc at 3, 5, 7 and 9 days were valuable for evaluating the clinical outcome of patients with severe pneumonia, and 9-day PCTc had the greatest value, the AUC was 0.978 [95% confidence interval (95%CI) = 0.945-1.000, P = 0.000], which was higher than APACHEⅡ(AUC = 0.442, 95%CI = 0.280-0.610, P = 0.392); when the best cut-off value of 9-day PCTc was 93.00%, its sensitivity was 99.0%, and specificity was 87.3%. Conclusions The PCT level of patients with severe pneumonia remained at a high level, which was related with the deterioration of the disease. PCTc, as an index to evaluate the clinical outcome of patients with severe pneumonia, has good application value.

Objective:To investigate the relationship between microsatellite instability (MSI) , and clinicopathological features ,prognosis in patients with stage Ⅱ and Ⅲ colon cancer.Methods:Patients undergoing surgical resection for stage Ⅱ and Ⅲ colonic tumor in the Affiliated Hospital of Qingdao University from Dec 2016 to Nov 2018 were enrolled. All the 292 patients were with stage Ⅱ and Ⅲ colon cancer and MSI status. Propensity score matching method was used to match the two groups of patients according to 1:1. χ 2 analysis, Logistic Regression and COX regression was used to analyse the relationship between MSI status, the clinicopathological features and prognosis. Results:The risk of MSI-H in young patients ( OR=0.340, 95% CI: 0.126~0.921, P=0.034), right-sided colon cancer ( OR=7.985, 95% CI: 3.040-20.973, P<0.001), mucinous adenocarcinoma ( OR=4.285, 95% CI: 1.495-12.284, P=0.007), poorer differentiation ( OR=4.848, 95% CI: 1.597-14.716, P=0.005), N0 staging ( OR=0.235 , 95% CI: 0.077-0.719, P=0.011) increased . The total OS of colon cancer patients in the MSS group (66.7%) and the MSI-H group (86.9%) were statistically different( P=0.003). The MSI status ( HR=0.367, 95% CI: 0.151-0.891, P=0.027) is an independent factor affecting the prognosis of patients. Conclusions:In stage Ⅱ and Ⅲ colon cancer, patients with MSI-H have a better prognosis. MSI status is prognosis relevant factor for colon cancer patients.

Objective To explore the influence of self-efficacy on self-manageemnt behavior and blood glucose control in diabetes patients. Methods A total of 435 diabetes patients chosen by convenience sampling method, were surveyed by the Chinese diabetes management self-efficacy scale ( C-DMSES) and Chinese version scale of the diabetes self-care activities ( SDSCA) . Results Score of self-efficacy for 435 patients with diabetes was (132. 28 ± 38. 66) and 63. 91% patients were in the moderate level; self management behavior survey indicated that 58. 85% patients had the moderate self-care levels. Only 22. 76% of the patients achieved the target goal of blood glucose. Self-efficacy and self-care behavior of patients were positively correlated ( P <0. 05), while HbA1c and self-care behavior and self-efficacy were negatively correlated ( P < 0. 05 ). Multivariate liner regression analysis showed that self behavior explained by self-efficacy was 33. 26% variance, 7. 4% variance of HbA1c were explained by self-efficacy. Conclusions Self-efficacy and self-care behavior of diabetes patients are in medium level. Good self-efficacy may improve self-care behavior and blood glucose control of diabetes patients.

Objective: To summarize the clinical data of 15 patients with fibrodysplasia ossificans progressiva (FOP), follow up and analyze the characteristics of the joint involvement in FOP. Method: From May 2005 to December 2016, fifteen FOP cases had been diagnosed in the Children′s Hospital Capital Institute of Pediatrics. All medical records and follow-up data were collected and a retrospective analysis was made on the joint involvement in FOP. Pearson correlation analysis was used for data, P<0.05 for the difference was statistically significant. Result: There were 8 males and 7 females in 15 cases. The age of onset was 2(1-6)years. The age at diagnosis was 6 (4-9) years. All cases had hallux valgus deformity and bone mass formation. Twelve cases had joints involvement on enrollment into this study: 8 cervical vertebra, 7 shoulder joint, 5 hip joint, 4 elbow joint, 3 wrist joint, 2 temporomandibular joint, 2 lumbar vertebra. The age of diagnosis and duration of disease were positively correlated with the number of the involved joints (r=0.523, 0.628; P=0.045, 0.012); mild changes were found in joint imaging. Thirteen cases received telephone follow-up, the average duration of follow-up was 6(3-7)years, no change in 11 cases, disease progress in 2 cases. Conclusion Joint involvement is a common complication of FOP, especially the cervical vertebra.Multiple joints involvement, dominant functional impairment, and mild imaging changes are the characteristics of joint lesions caused by FOP.The number of involved joints gradually increases with increase of age of the patients and the prolonged course of the disease.

Objective To summarize the clinical characteristics of Beh?et's disease (BD) in children with gastrointestinal involvement. Methods We retrospectively analyze the children BD with gastrointestinal involvement who were diagnosed in our hospital in recent 10 years. Results Twenty-two children were identified. The average age of onset was(6.1±4.0) years. The time from disease onset to clinical diagnosis was (1.2±2.1) years on average. Fifteen children had abdominal pain, diarrhea and hematochezia. Seven cases had positive endoscopic findings without any gastrointestinal symptoms. Twenty cases received corticosteroids therapy, 13 cases of them were treated with Cyclophosphamide/Methotrexate (CTX/MTX), 3 refractory cases were treated with biologics. Patients were followed up for (28±32) month on average. Eight patients' condition was stable, 7 patients were refractory, 3 patients died, 4 patients were lost to follow-up. At the same term, 5 patients without gastrointestinal involvement who received corticosteroids and CTX/MTX therapy were stable. Conclusion It is difficult to diagnose children BD at early stage. Gastrointestinal involvement may not be found, while the gastrointestinal endoscopy is of great importance in the diagnosis of the disease. Gluco-corticoid combined with immunosuppressive agents are effective. As to refractory patients, biological agent might be used although the recurrence is common. Compared with BD without gastrointestinal involvement, children BD with gastrointestinal involvement have serious condition and poor prognosis.

Objective:To investigate the clinical pathological features of primary pulmonary and tracheal glomus tumors.Methods:The clinical and pathological features of 11 cases (4 cases from Shanghai Pulmonary Hospital, Tongji University School of Medicine, China and 7 cases from Fudan University Shanghai Cancer Center, China) of respiratory glomus tumor diagnosed from 2010 to 2019 were analyzed, and reviewed in light of the relevant literature.Results:In the 11 cases, there were 5 males and 6 females, with the onset ages of 29?66 years (median age of 43). Six tumors were located in the lung, and 5 in the trachea. The tumor diameters ranged 1.0?7.5 cm, with the average diameter of 2.6 cm. At low magnification, the tumors were diffuse or lobulated in shape. The tumor cells composed of sheets of oval to short spindle cells, with sharply defined cell border and prominent branching thin-walled vessels. Among the 4 benign glomus tumors, one was classified as benign symplastic glomus tumor owing to the hyperchromatic or degeneration nuclei. Two cases were classified as glomus tumors of uncertain malignant potential, on the account of cellular atypia and rare atypical mitotic figures. Five cases were classified as malignant glomus tumors, owing to the tumor necrosis, vascular invasion, marked nuclear atypia, prominent nucleoli and brisk mitoses (2-20/10HPF) including pathological mitotic figures. The tumor cells showed strong immunostaining for SMA, vimentin, type Ⅳ collagen and caldesmon to different extents, while CD34, cytokeratin and S-100 stains were negative. One of the cases was positive for desmin, and one case positive for synaptophysin. Follow-up information was available in 8 patients with the duration ranging from 6 to 95 months. At the end of the follow-up, 6 patients were alive without recurrence or metastasis, and two of the patients with malignant glomus tumors died.Conclusions:Primary pulmonary and tracheal glomus tumors is rare. Among the reported cases, malignant glomus tumor is the most frequent, followed by benign glomus tumors and uncertain malignant potential glomus tumors. Glomus tumors show sheet-like growth pattern and clusters of round epithelioid cells with numerous vascular spaces. They can be easily misdiagnosed as carcinoid tumor. The final diagnosis should be combined with immunohistochemical staining, such as SMA, caldesmon and vimentin.

Objective:To investigate the distribution of potential suitable habitats for Ixodes persulcatus in Heilongjiang Province during different climatic periods. Methods:The geographical location data of Ixodes persulcatus in Heilongjiang Province from 1980 to 2023 were collected through literature search and field ecological investigation. The environmental factor variables were downloaded from the WorldClim website and the Resource and Environmental Science and Data Platform. A combination of SDMtune, ENMTools packages, and the maximum entropy (MaxEnt) model were used to predict the potential habitats of Ixodes persulcatus in Heilongjiang Province during different climatic periods and determine its dominant environmental factors. Among them, the time range of historical climatic period data was 1970 - 2000. The future climatic period data (2021 - 2040, 2041 - 2060) were selected as the low forcing scenario (SSP126 scenario) of the shared socioeconomic pathways (SSP) in the Beijing Climate Center - Climate System Model version 2-Medium Resolution, to simulate the impact of global warming on the distribution of potential habitats for Ixodes persulcatus in Heilongjiang Province. Results:A total of 83 geographical distribution sites of Ixodes persulcatus in Heilongjiang Province were obtained. After screening, 10 environmental factors were included in the MaxEnt model. Among them, the cumulative contribution percentage of annual precipitation, average annual temperature, and vegetation type was 67.3%. Compared with historical climatic period, the total potential habitats of Ixodes persulcatus in Heilongjiang Province increased from 29.81 × 10 4 km 2 to 32.24 × 10 4 km 2 in 2041 - 2060. The center of potential habitats moved to 47.75° N, and 128.66° E, with a northwest offset of 126.07° and a migration distance of 45.83 km. Conclusion:With global climate warming, the total potential habitats of Ixodes persulcatus in Heilongjiang Province has increased, showing an overall trend of migration to the northwest.

Diabetic kidney disease （DKD） is one of the common microvascular complications of diabetes mellitus （DM） and a primary cause of chronic kidney disease （CKD） and end-stage renal disease （ESRD）. Inflammation is currently a hot topic in exploring the pathogenesis of DKD. Macrophages， T cells， interleukins， tumor necrosis factor， NOD-like receptor protein 3 （NLRP3） inflammasome， Janus kinase/signal transducer and activator of transcription （JAK/STAT） signaling pathway， and nuclear factor-kappa B （NF-κB）-related signaling pathway all play a role in regulating the inflammation of DKD and accelerating its progression. Astragali Radix， a Chinese herbal medicine， is widely used in the treatment of DKD and possesses strong anti-inflammatory effects. Studies have revealed that active ingredients of Astragali Radix， including polysaccharides， astragaloside Ⅳ， total flavonoids， calycosin， and quercetin， can regulate multiple signaling pathways to ameliorate the microinflammatory state and alleviate kidney damage， thereby slowing down the progression of DKD. This article systematically reviews the factors influencing the inflammation in DKD and analyzes recent research findings and mechanisms concerning active ingredients of Astragali Radix in the management of DKD inflammation， aiming to offer novel insights and directions for the prevention， treatment， and research of DKD.
