Objective To analyze flaws in diagnosis and coding of diseases on the first pages of inpatient medical records and explore solutions to improve the accuracy of record-filling in tertiary hospitals.Methods A retrospective analysis was con-ducted to assess the quality control and logical verification data from the first pages of inpatient records at a tertiary hospital,col-lected from January to December 2023.Results A total of 463 flaws were identified,including 99 flaws in primary diagnostic selection,accounting for 21.37％,148 flaws in primary surgical selection accounting for 32.00％,33 omissions in secondary di-agnoses,accounting for 7.12％,and 121 omissions in surgical procedures accounting for 26.12％.Primary diagnostic errors were primarily attributed to failure to specify etiology,with the highest number of 24 cases(24.24％),followed by overgeneral-ized diagnostic descriptions,with 15 cases(15.15％).Totally,169 coding errors were identified,including 61 logic errors(36.09％),58 coding omissions(34.33％),and 30 uncombined coding cases(17.75％).Conclusion There are significant flaws in the coding on the first pages of medical records.It is imperative to strengthen the training for clinicians and coders and enhance quality control through intelligent automation.These measures are crucial for improving the quality control of the first pa-ges of medical records.

Objective:To investigate characteristics of the 18F-flurodeoxyglucose ( 18F-FDG) uptake intensity and ranges in distinct hepatic alveolar echinococcosis lesions. Methods:The clinical data of 39 patients with position emission tomography during Jan 2017 to Dec 2019 in the First Affiliated Hospital of Xinjiang Medical University were enrolled. Among them, there were 17 males and 22 females, aging from 15 to 65 years (median 34 years). Lesions were classified into six groups based on heterogenic scales of calcification and liquefaction: A. non-calcified and non-liquefied ( n=7); B. obvious calcified and non-liquefied ( n=7); C. partial calcified and partial liquefied( n=10); D. obvious calcified and partial liquefied ( n=5); E. partial calcified and subtotal liquefied ( n=5); F. obvious calcified and subtotal liquefied ( n=5). Tumor to background ratio (TBR) and width (W) of lesion infiltrative boundary were measured and calculated. Statistical comparison using Mann-Whitney U test as well as correlation analysis was performed. Results:TBR values [ M( Q1, Q3)] for each group were 4.40(3.66, 7.03), 2.55(1.69, 3.60), 3.73(3.37, 5.21), 2.90(2.75, 3.60), 3.80(3.49, 6.36), 2.49(2.21, 3.97), among which A>B, A>D, A>F, C>B, E>B ( U=3.0, 4.0, 4.5, 11.0, 5.0, all P<0.05); From the perspective of the calcification in each group, it was found that the lighter the calcification was, the greater the TBR value was. W values [ M( Q1, Q3)] for each group were [12.5(10.0, 19.5), 11.2(10.5, 12.5), 12.2(10.9, 13.2), 7.8(7.3, 9.3), 10.0(7.3, 13.4), 7.3(6.8, 7.6)] mm, among which A>D, A>F, B>D, B>F, C>D, C>F (all U=0, all P<0.05); According to the degree of calcification and liquefaction of lesions in each group, the lighter the calcification was, the greater the W value was; The heavier the liquefaction was, the smaller the W value was. A mild strength linear correlation has been observed between the TBR value and W value ( r=0.4136, P<0.05). Conclusions:Less calcification and liquefaction implicated higher 18F-FDG uptake intensity and wider range. Radical resection margins and tissue sampling should be individualized based on different lesion features in surgical treatment.

Human alveolar echinococcosis is a chronic infectious disease caused by Echinococcus multilocularis infection. It predominantly injuries the liver and grows like the malignant tumor. The therapeutic options and prognosis depend on types of human alveolar echinococcosis, clinical stages, biological activity, vascular invasion, pathological characteristics, and patient's immune status. However, despite of multiple classification methods, there are still lacking of comprehensive typing schemes. which leads to inappropriate diagnosis and therapy. This research systematically reviewed the recent studies on human alveolar echinococcosis at home and abroad and analyzed the classifications based on ultrasound, computer tomography, magnetic resonance imaging, positron emission computed tomography, serology and pathology, and some novel technologies and summarized the individual advantage and disadvantage for each classification Relationships and their advantages plus disadvantages have been assessed comprehensively. Meanwhile, the possible reference factors or theoretical basis for optimized future classification are proposed, in order to establish a unified classification system to provide guidance for clinical diagnosis and treatment.

Objective To investigate the prevalence and trend of dental fluorosis of 7-14 years old children in 134 Regiment,8 Division,Xinjiang Production and Construction Corps,and to evaluate the effectiveness of water improvement and fluoride control measures.Methods From 2010 to 2017,using cross-sectional survey,six water allocation places were selected from 134 Regiment,8 Division,Xinjiang Production and Construction Corps,and the fluoride content was determined.Children of 7-14 years old in 2 central primary schools were investigated,and dental fluorosis was examined.Taking 2017 as the benchmark,children born before water improvement were 11-14 years old,children born after water improvement were 7-10 years old.Water fluoride was detected via the ion-selective electrode method.Diagnosis of dental fluorosis was based on the standard of "Dental Fluorosis Diagnosis" (WS/T 208-2011).The detection rate of dental fluorosis was compared by x2 test,and rank sum test was used to compare the severity of the disease.Results A comprehensive water improvement and fluoride reduction project was completed in 134 Regiment,8 Division,Xinjiang Production and Construction Corps in 2007.The detection rate of dental fluorosis in children born before water improvement was 2.65 times higher than that of children born after water improvement [14.43％ (101/700) vs 5.44％ (33/607),X2 =28.567,P ＜ 0.01].The dental fluorosis index of children born before water improvement was also higher than that of children born after water improvement (0.33 vs 0.11).According to age standardization (based on 2017),there was a significant difference in the detection rate of dental fluorosis among children in different years (x2 =351.300,P ＜ 0.01).The detection rate of dental fluorosis in children decreased from 35.26％ in 2010 to 10.25％ in 2017.There was a statistically significant difference in the severity of dental fluorosis in children of different years (H =954.033,P ＜ 0.01).The dental fluorosis index of children decreased from 0.71 in 2010 to 0.23 in 2017,and the disease changed from extremely mild fluorosis epidemic to non-fluorosis epidemic.Conclusion After effective water improvement in 134 Regiment,8 Division,Xinjiang Production and Construction Corps,the prevalence of dental fluorosis in children in the disease affected areas has decreased significantly,the effect of defluoridation project is significant.

Objective To construct a colon cancer chemotherapy-resistant cell line COLO,and study its characteristics and its relationship with tumor stem cells.Methods We constructed two 5-fluorouraci (5-FU)-resistant colon cancer cell line COLO/5-FU-1 and COLO/5-FU-2, which were resistant to 0.1 0 μmol/ml and 0.20 μmol/ml 5-FU respectively through gradiently increased drug concentration.The cha-racteristics of 5-FU-resistant cell lines were compared with parental colon cancer cell line COLO related to proli-feration,colony forming ability,migration and invasion,sphere forming ability,expression of stemness genes and cross drug-resistance.Results In the cell viability assay,4 days after regular training,the absorbancy of colon cancer 5-FU-resistant cell lines COLO/5-FU-2,COLO/5-FU-1 and parental colon cancer cell line COLO were 0.61 ±0.1 3,0.54 ±0.07 and 0.41 ±0.09 respectively,with significant difference (F =63.43,P =0.033).With the increased concentration of 5-FU,5-FU-resistant cell lines presented increasing clonality. The cloning efficiency of COLO/5-FU-2,COLO/5-FU-1 and parental colon cancer cell line COLO were (87.6 ±1 2.7)%,(65.3 ±9.7)% and (38.5 ±7.6)% respectively,with significant difference (F =33.64, P =0.01 7).In each high power field of vision,the cell numbers of migration through the basement membrane of COLO/5-FU-2,COLO/5-FU-1 and parental colon cancer cell line COLO were 482 ±39,434 ±45 and 373 ±38 respectively;and the cell numbers of invasion through the basement membrane were 1 74 ±42,1 1 2 ± 31 and 87 ±29 respectively,with significant differences (F =1 09.61 ,P =0.009;F =67.31 ,P =0.032). Compared with parental colon cancer cell line COLO,5-FU-resistant cell lines had higher expression of stem-ness genes (F =47.31 ,P =0.042).5-FU-resistant cell lines were cross-resistant to other chemotherapeutic drugs such as mitoxantrone.For example,after incubation for 96 hours,inhibition rate of mitoxantrone to parent colon cancer cell line COLO was higher significantly than COLO/5-FU-1 and COLO/5-FU-2 (0.749 ± 0.042,0.423 ±0.024,0.342 ±0.01 8),with significant difference (F =1 2.61 ,P =0.028).The micro-sphere forming rates of COLO/5-FU-2,COLO/5-FU-1 and parental colon cancer cell line COLO were (8.90 ± 0.97)%,(6.20 ±0.75)% and (3.90 ±0.32)% respectively,with significant difference (F =1 64.32,P =0.006).Conclusion Colon cancer drug-resistant cell line COLO possess tumor stem cell-like characteristics, which are enriched in cancer stem cells.

The UL49.5 gene of most herpesviruses is conserved and encodes glycoprotein N. However, the UL49.5 protein of duck enteritis virus (DEV) (pUL49.5) has not been reported. In the current study, the DEV pUL49.5 gene was first subjected to molecular characterization. To verify the predicted intracellular localization of gene expression, the recombinant plasmid pEGFP-C1/pUL49.5 was constructed and used to transfect duck embryo fibroblasts. Next, the recombinant plasmid pDsRed1-N1/glycoprotein M (gM) was produced and used for co-transfection with the pEGFP-C1/pUL49.5 plasmid to determine whether DEV pUL49.5 and gM (a conserved protein in herpesviruses) colocalize. DEV pUL49.5 was thought to be an envelope glycoprotein with a signal peptide and two transmembrane domains. This protein was also predicted to localize in the cytoplasm and endoplasmic reticulum with a probability of 66.7%. Images taken by a fluorescence microscope at different time points revealed that the DEV pUL49.5 and gM proteins were both expressed in the cytoplasm. Overlap of the two different fluorescence signals appeared 12 h after transfection and continued to persist until the end of the experiment. These data indicate a possible interaction between DEV pUL49.5 and gM.

ObjectiveTo investigate the expression of programmed death receptor ligand 1 ( PD-L1 ) of peripheral blood mononuclear cells (PBMCs) in patients with hepatic cystic echincccccosis (HCE) and its relation with interferon-γ.MethodsThe clinical data of 63 patients with HCE who were admitted to the First Affiliated Hospital of Xinjiang Medical University from June 2010 to February 2011 were retrospectively analyzed.All patients were divided into HCE active group (38 patients) and HCE non-active group (25 patients) according to the system established by the World Health Organization's Informal Working Group on Echinocoecosis.Twenty patients with hepatic hemangioma or healthy individuals were recruited in normal control group.The positive rate of PD-L1 expression was detected by flow cytometry and immunocytochemistry.The expression of interferon-γ was detected by enzyme-linked immtmosorbent assay (ELISA).All data were analyzed by the t test,one-way analysis of variance,LSD test and chi-square test.The relationship between the expression of interferon-γ and positive rate of PD-L1 expression was analyzed by the Pearson test.ResultsThe results of flow cytometry showed that the positive rates of PD-L1 expression in the HCE active group,HCE non-active group and normal control group were 12.1％±3.8％,10.9％ ± 2.5％ and 9.1％ ±2.5％,respectively.There was a significant difference in the positive rate of PD-L1 expression between the HCE active group and normal control group (t =3.327,P ＜ 0.05 ).The results of immunohistochemistry showed that the positive rates of PD-LI expression in the HCE active group,HCE non-active group and normal control group were 11.9％ ± 3.4％,i0.6％ ± 2.9％ and 9.5％ ± 3.6％,respectively.There was a significant difference in the positive rate of PD-L1 expression between the HCE active group and normal control group (t =2.470,P ＜ 0.05 ).The expressions of intefferon-γ in the HCE active group,HCE non-active group and normal control group were ( 141 ± 38 ) μμg/L,( 124 ± 32 ) μg/L and ( 105 ± 42 ) μg/L.There wasasignificant difference in the expression of interferon-γ between the HCE active group and normal control group ( t =3.280,P ＜ 0.05).The results of flow cytometry and immunohistochemistry revealed that the positive rate of PD-L1 expression was positively correlated with the expression of interferon-γ( r =0.59,0.61,P ＜ 0.05 ).Conclusion With the help of interferon-γ,PD-L1 may play an important role in promoting the immune.evasion of echinococcus.

In this study, apoptosis was induced by new type gosling viral enteritis virus (NGVEV) in experimentally infected goslings is reported in detail for the first time. After 3-day-old goslings were orally inoculated with a NGVEV-CN strain suspension, the time course of NGVEV effects on apoptotic morphological changes of the internal tissues was evaluated. These changes were observed by histological analysis with light microscopy and ultrastructural analysis with transmission electron microscopy. DNA fragmentation was assessed with a terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling (TUNEL) assay and DNA ladder analysis. A series of characteristic apoptotic morphological changes including chromatin condensation and margination, cytoplasmic shrinkage, plasma membrane blebbing, and formation of apoptotic bodies were noted. Apoptosis was readily observed in the lymphoid and gastrointestinal organs, and sporadically occurred in other organs after 3 days post-infection (PI). The presence and quantity of TUNEL-positive cells increased with infection time until 9 days PI. DNA extracted from the NGVEV-infected gosling cells displayed characteristic 180~200 bp ladders. Apoptotic cells were ubiquitously distributed, especially among lymphocytes, macrophages, monocytes, and epithelial and intestinal cells. Necrosis was subsequently detected during the late NGVEV-infection phase, which was characterized by cell swelling, plasma membrane collapse, and rapidly lysis. Our results suggested that apoptosis may play an important role in the pathogenesis of NGVE disease.

Objective To explore the expression of TLR2,4,7 mRNA on peripheral blood mono-nuclear cells (PBMCs) in patients with chronic cystic echinococcosis(CE) infection, and the level of serum IL-10. Methods The expression level of TLR2,4,7 mRNA on peripheral blood mononuclear were tested in 42 chronic CE cases and 28 normal controls (NC) by real-time fluorescent quantitative reverse transcription polymerase chain reaction (FQ-RT-PCR) method. GAPDH was selected as the internal control. The level of serum IL-10 was determined in ELISA. The subjects were determined by t test. The correlations between TLR2, TLR4, TLR7 and IL-10 were determined by differences of expression of TLR2, TLR4, TLR7 on PBMCs and serum IL-10 in two groups of study linear correlation test. Results The expressions of TLR2, TLR4,TLR7 mRNA in chronic CE group were higher than those of in NC group. Compared with the NC group, the expressions of TLR2, TLR4 and TLR7 mRNA increased more than 7.3-, 3.6-, 3.6-fold, respectively. In chronic CE group, TLR2, TLR4 and TLR7 mRNA expressions were 1.0729 ±0.4006, 5.0976 ±1.6682, 0. 6481 ±0. 2574, respectively. TLR2, TLR4 and TLR7 mRNA expressions were 0. 1468 ± 0.0435, 1.4067 ±0. 3279, 0. 1804 ±0. 0568 in NC group, respectively. Compared with NC group, the differences of TLR2 and TLR4 mRNA expression were significant (P = 0.0287, 0. 033), while the expression of TLR7 mRNA was not difference (P =0.0862). Moreover, in chronic CE group, the level of serum IL-10 was higher than that of in NC group. In chronic CE group and NC group, the level of serum IL-10 was (17.6770±1.6298) pg/ml, (9.4898 ±0.7049) pg/ml. Compared with NC group, there was significant difference in chronic group (P<0.01). Significant positive correlation between TLR2 and TLR4 was found in chronic CE group, r = 0. 1135, P =0.036. Others were not correlations. Conclusion In the development of chronic CE, TLR2 and TLR4 participate in this progression. As the receptors of antigen of cystic echinococcus, TLR2 and TLR4 can regulate the immune response through interacting with different antigens from cystic echinococcus. Meanwhile, under the participation of TLR2, TLR4 and increased serum IL-10, they will approach to Th2 immune reaction, which play an important role in chronic CE that can induce immune evasion.

Objective To screen for Kaposi sarcoma (KS)-related genes. Methods Tissue samples were obtained from the lesion and normal skin of a patient with KS in Xinjiang Uygur Autonomous Region,and total RNA was extracted from these samples and reverse transcribed into cDNA. Real-time fluorescent quantitative reverse transcription PCR (RT-qPCR) was performed to determine the expression of K8.1, K2 and ORF50 in these samples. The cDNA was labeled with fluorescein and hybridized to a human 35K genome array containing 25 100 genes. Subsequently, the signal images were scanned by a laser scanner and acquired images were analyzed by software. Results RT-qPCR revealed the mRNA expression of K8.1, K2 and ORF50 in the KS tissues but not in the normal skin tissues, indicating that there was no crossed contamination in these specimens. Among the 25 100 genes, 1313 genes were identified to be differentially expressed between KS and normal skin tissues, including 756 up-regulated genes and 557 down-regulated genes. These differentially expressed genes, such as myeloid cell leukemia-1 gene (MCI-1), annexins (ANX) and serine proteinase inhibitor Kazal type 5 (SPINK5), were associated with apoptosis, angiogenesis, cell signaling, protein processing, cell cycle regulation, and so on. Conclusion The differentially expressed genes such as MCI-1 and SPINK5 may be associated with the development of KS.
