RESUMEN
ObjectiveTo construct a quantitative differentiation model of traditional Chinese medicine （TCM） syndromes by taking primary osteoporosis （POP） with kidney yang deficiency syndrome as an example， and to provide methodological reference for the standardization of syndrome differentiation. MethodsHigh-frequency clinical features of POP were screened by descriptive statistical analysis， and strong association features of POP were obtained by association rule algorithm. On this basis， a latent structure （latent tree） model was established through latent structure analysis， and the implicit and explicit variables （features） related to POP with kidney yang deficiency syndrome were comprehensively clustered， and the clustering results were interpreted by the indexes of mutual information and cumulative information coverage， to explore the primary and secondary symptoms， and to deduce the categories of POP with kidney yang deficiency syndrome based on the probability of the features appearing in the various latent categories. Based on the categories， the clinical feature scores and identification thresholds were calculated， and the syndrome differentiation model of POP with kidney yang deficiency was initially constructed by combining the comprehensive judgment rules. Finally， the results of TCM professionals' judgment were used as the gold standard to further evaluate the effectiveness of the model in assisting the syndrome differentiation. ResultsThe 32 features strongly associated with POP were obtained， and the Bayes information critedon score of the further constructed latent tree model was -15291.93. Based on the mutual information and the cumulative information coverage， the main symptoms of POP with kidney yang deficiency syndrome were bone weakness， fatigue， pale tongue， clear urine， frequent nocturnal urination， cold limbs， thin pulse， white coating， and secondary symptoms were weakness， loss of libido， loose stool， frequent urination， lumbar and knee weakness， and fear of cold. From the probability of the occurrence of each clinical feature in different latent categories of POP with kidney yang deficiency syndrome， the state was introduced as S0 category （none/mild kidney yang syndrome）/ S1 category （moderate kidney yang syndrome）/ S2 category （severe kidney yang syndrome）. Optimizing the preliminary rules of state identification and refining the state of S1 category， the results showed that among 970 patients with POP， there were 520 patients having no/mild kidney yang deficiency syndrome， 224 patients with moderate to mild kidney yang deficiency syndrome， 81 patients with moderate to severe kidney yang deficiency syndrome， and 145 patients with severe kidney yang deficiency syndrome. During the evaluation and validation process， the correct rate of the model assessment index was 0.8835， while the sensitivity was 0.7181， and the specificity was 0.9437. ConclusionCombined with the latent structure analysis of the association rule， the syndrome differentiation model for POP with kidney yang deficiency could be constructed， and the model shows a good quantitative identification effect， which can provide methodological supports for clinicians to improve the efficiency and accuracy of TCM diagnosis.
RESUMEN
Objective:To investigate the effect of the combination of Auto-prescription and ODM full on image quality and radiation dose of chest enhanced CT inorder to explore the feasibility of individualized low radiation dose chest enhanced CT. Methods:The phantoms PH-75 in two sizes were scanned with four scanning modes: group A, 120 kVp + Smart-mA; group B, 120 kVp + Smart-mA+ ODM full; group C, Auto-prescription + Smart-mA; group D, Auto-prescription + Smart-mA+ ODM full. The images of each group were reconstructed with 40%-80% ASIR-V (interval 20%), recorded as A 1-3-D 1-3. Image quality and radiation dose were evaluated in order to obtain optimal scanning modes. Totally 35 cases(from the First Hospital of Dalian Medical University during November 2021 to July 2022) of chest enhancement CT were collected prospectively in the clinical study using the parameters of D 2 group recorded as D patients. Patients in this group received chest enhancement CT scanning for the second time within three months. The CT parameters in first enhanced scanning recorded as A patient were as same as those in group A 1, and the parameters in second scanning recorded as D patient were as same as those in group D 2. The SNRs, CNRs, subjective grading and imaging findings of the lesion in two groups were compared. Results:In phantom study, the radiation dose of each group was statistically significant, and that in D group was the lowest. For two sizes of phantoms, A 1 was uesd as the control group in pairwise comparison. The SDs of B 1, C 1, and D 2 images had no statistical difference with that of A 1 ( P > 0.05), and SD of D 1was higher than that of A 1, and SDs of other groups were lower than that of A 1( F=10.77, 122.50, P<0.05). CNR of B 1 had no statistical difference with that of A 1, and the CNRs of other groups were higher( F=136.20, 30.21, P<0.05). Subjective scores of A 2, C 2, D 2 had no statistical difference with that of A 1 and those of other groups were lower than that of A 1( H=52.89, 43.95, P<0.05). In clinical study, 80 kVp was uesd for 22 cases and 100 kVp was used for 13 cases in D patients group. SNRs and CNRs in the D patients group were all higher than those in the A patients group ( P > 0.05). The consistency of image quality scores for two observers was good ( kappa = 0.754, P < 0.05). The median scores of the two groups were (4, 4). Conclusion:Auto-prescription combined with ODM full in chest enhanced CT imaging can achieve individualized low radiation dose with meeting the requirements of image quality and clinical diagnosis.
RESUMEN
ObjectiveTo screen the risk factors of osteoporosis in perimenopausal women， and to provide direction for timely prevention and treatment. MethodsUsing multilevel stratified random sampling method， the perimenopausal women were investigated by questionnaire survey， and the determination of bone mineral density （BMD） and the levels of several important hormones. ResultsA total of 720 valid questionnaires were received. Among 720 perimenopausal women， 173 had osteoporosis and 547 had no osteoporosis. Univariate analysis of the influencing factors of osteoporosis showed that the levels of parathyroid hormone （PTH）， Estradiol （E2）， body mass index （BMI）， age， time of last period and age of menopause were significantly different among perimenopausal women in the prevalence of osteoporosis（χ2=4.23， 4.86， 16.06， 21.04， 10.52， 13.02； P<0.05）.Logistic regression analysis showed that the increase of PTH （OR=2.70， P<0.05）and menopause （OR=1.76， P<0.05） were the risk factors of osteoporosis . Higher BMI（OR=0.65， P<0.05）， higher personal monthly income（OR=0.72， P<0.05）， longer sunshine time（OR=0.69， P<0.05）， were the protective factors against osteoporosis. ConclusionThe increase of PTH levels and menopause are the risk factors for osteoporosis in women. Perimenopausal women should be monitored for bone mineral density and appropriate intervention. Necessary treatment measures should be taken for the patients with osteopenia and osteoporosis.
RESUMEN
Primary hospitals are engaged in such responsibilities as diagnosis and treatment of endemic diseases and common illnesses of the locality, as well as relevant research work which bears more prominent importance than ever before. Given the importance of research, the hospitals are mostly plagued by such setbacks as obsolete research management concepts, poor experiences, poor perception of research, poor professional competency and lack of academic exchange among the medical workers. A primary hospital had set up a novel management mechanism, featuring " full-staff involvement, full-process supervision and full-dimensional guidance" , and " tight formal examination and tight content examination" . This mechanism has been in place since 2016 in research project management practice, achieving such progresses as significant rise in the number of research project applications, that of approved projects, and project implementation capabilities.Future improvements in this regard should be made in higher pertinence, optimized management flow and better research service system.

RESUMEN
Objective@#To investigate the distributions of Candida albicans (Ca), which are closely associated to early childhood caries (ECC) of young children, in 3-5-year-old children of Mongolian, Uygur and Han ethnic groups in Bortala Mongol Autonomous Prefecture of Xinjiang Urgur Autonomous Region, so as to provide scientific basis for the early prediction and prevention of caries locally.@*Methods@#Totally 1 089 healthy children aged 3 to 5 years old (Mongolian 136, Uygur 403 and Han 550; 568 males and 521 females) were randomly selected by stratified and cluster sampling method. The children in early childhood caries group were 786 and in caries free group were 303. Dental plaque samples were collected from the carious tooth tissues and supragingival sites, respectively. Samples were isolated and cultured by different media. Ca were identified by Gram stain, germ tube test, PCR method and internal transcribed spacer region sequencing methods. Ca isolated were further typed by using PCR-25SrDNA genotype method. Pearson χ2 test and Spearman rank correlation were used to analyze the differences in genotypes of Ca amongst three ethnic groups and the relationship between decayed missing filled tooth (dmft) classification and detection of Ca.@*Results@#The Ca was significantly higher in the ECC group [14.4% (113/786)] than in the caries free group [7.6% (23/303)] (P=0.002). The identified rate of Ca in Mongolian group was [11.8% (16/136)], which was significantly lower than that of Uygur group [17.9% (72/403)] and higher than that of Han group [8.7% (48/550)] (χ2=10.192, P=0.006). Among the male children, the identified rate of Ca in Mongolian group was [10.0% (8/80)], which was significantly lower than that of Uygur group [21.7% (44/203)] and higher than that of Han group [8.4% (24/285)] (χ2=18.887, P=0.000). Among the female children, the detection rates of Ca were [14.3% (8/56)] in Mongolian group, [14.0% (28/200)] in Uygur group and [9.1% (24/265)] in Han group. There were no significant differences among the three ethnic groups (χ2=3.206, P=0.201). The identification rates of oral Ca in Uygur and Han ECC groups were correlated with the decayed, missing and filled teeth (Uygur r=0.195, P=0.001; Han r=0.145, P=0.004). Totally 136 Ca samples were divided into 3 types by PCR-25SrDNA method, and the predominant type was type A [55.1% (75/136)].@*Conclusions@#The distribution of oral Ca among children were ethnically different. Uygur male children carrying Ca were more susceptible to dental caries. Ca might be a risk factor for ECC. There was no specific cariogenic genotype in Ca isolated. There were no associations between ethnic factors and the genotypes of Ca isolated.

<p><b>OBJECTIVE</b>To compare the biological behaviors of two drug-resistant testicular cancer cell lines established by different methods.</p><p><b>METHODS</b>Drug-resistance was induced in testicular cancer cell lines exposure of the cells to increasing concentrations of or a high dose of cisplatin (I-10/DDPi and I-10/DDPh cell lines, respectively). The morphological characteristics of the two cell lines were observed microscopically. The resistance index of the cells was determined with MTT assay, and the cell growth curves were drawn. The cellular expression of resistance-associated proteins MDR1 and P-gp was detected by Western blotting. The cell invasion ability was assessed with Transwell assay.</p><p><b>RESULTS</b>Normal testicular cancer cell line I-10 and the two resistant cell lines all showed an adherent growth pattern. Compared with I-10 cells, I-10/DDP cells exhibited slightly heterogenous cell sizes, irregular shapes, the presence of microvilli tentacles on the cell surface, and a scattered arrangement. The cisplatin resistance index of I-10/DDPi and I-10/DDPh cells were 3.924 and 3.099, respectively. Compared with I-10, the drug-resistant cell lines showed extended doubling time with increased expressions of MDR1 and P-gp and increased cell invasiveness, which was especially obvious in I-10/DDPi cells.</p><p><b>CONCLUSION</b>Both increasing dose exposure and high-dose exposure to cisplatin can induce cisplatin resistance in testicular cancer cells, and the resistant cells established by the latter method better mimics clinical drug-resistant tumor cells.</p>

Objective To analyze the clinical,radiological and pathological features of primary leiomyosarcoma of bone and to im-prove the diagnostic level.Methods Totally 6 cases of PLB proved by pathology were collected in our study.The clinical,radiologi-cal and pathological findings were retrospectively analyzed,and combined with the relevant literature to have a comprehensive analy-sis.Results The lesions of 6 patients were solitary,located in femoral (1 case),distal femur (1 case),proximal tibia (2 cases),is-chium (1 case)and humerus (1 case).There was no periosteal reaction in all 6 cases but they all had soft tissue mass,sometimes there may have some mineralization within the tumor.Ill-defined osteolytic bone destruction was detected in 5 patients,while expan-sion of cystic bone destruction was found in the other 1 patients.3 cases had hardened edge,2 cases with adjacent bone cortical thickening.The MR imaging in 5 patients showed iso-intensity signal on T1 WI,a slightly inhomogeneously higher signal on T2 WI and a significant heterogeneously enhancement after injected of Gd-DTPA.Another 1 patient showed a double ring sign,the central area onT1 WI and T2 WI expressed heterogeneous slightly higher signal,the peripheral annular zone was iso-intensity on T1 WI and slightly higher on T2 WI,after injected contrast medium,it was inhomogeneous enhancement.In immunohistochemically,all tumors reacted positively with SMA,3 patients with Desmin and Vimentin positive,2 patients with Ki-67 positive,and there had some scat-tered cells with CD68 positive,but the S-100 were all negative.Conclusion The clinical,radiological and conventional histological manifestations of PLB are not specific.Immunohistochemical and/or ultrastructural analysis who displayed smooth muscle differenti-ation can confirm the diagnosis.
RESUMEN
Objective To discuss the possible enteric nervous pathogenesis in gastritis related GI motor disorders on the expression changes of protein gene product9. 5 in neurons from the gastric walls of gastritis rat model. Methods 35 clean grade Wister rats were randomly divided into 3 groups, which included gastritis group A (n =10), gastritis group B(n =15) and control group(n =10). Rats in gastritis group A and B received gastric perfusion of HP and the mixture of 2% aspirin and 0. 6N hydrochloric acid respectively. The control group only received gastric perfusion of saline. All of the rats were killed and the gastric mucosal tissues were obtained for the pathological and HP examination. After immunohistochemical pretreatment, the tissues were stained with PGP9. 5 and at the same time the maximum diameter (Dmax, μm), mean area(μm2) and mean optical density (nm) of the neurons from the gastric walls were compared among the groups with Image-Pro Plus professional image analysis system. Results In gastric group A, HP could be found sparsely in the mucous layer or gastric pits, and all of the rapid urease tests were positive. In the other two groups, HP could not be found, and all of the rapid urease tests were negarive. In both gastric group A and B, different grades of inflammatory cell infiltration with active inflammation signs could be found in the deep layers of mucosa, while the control group was normal. The expression mean area, mean optical density of neurons from the gastric wall of rat in group A[(77. 10 ±48. 46) μm2, (53. 25 ±41.40) nm] or B [(73. 92 ± 39. 60) μm2, (45.33 ± 33.20) nm] was obvious lower than control group [(143.51 ± 29. 84) μm2, (85. 00 ± 14. 32) nm], while there was no significant difference between gastric group A and B (P ＞0. 05) (table 1). Conclusions Hp and NSAIDs might cause gastritis and decrease the PGP9. 5 expression of Neurous from gastric walls. The decrease of PGP9. 5 expression of neurons from the gastric wall might contribute to the pathogenesis of GI motor disorders or symptoms of functional dyspepsia.
RESUMEN
Objective To find the possible pathogenesis of enteric nervous system, gut hormone and gastric Cajal interstitial cell ( ICC ) in gastritis related gastrointestinal ( GI ) motor disorders on the changes of protein gene product 9. 5 in neurons , mucosal expression of C-kit, gastrin and somatostatin from the gastric wall of gastritis rat. Methods 45 rats were divided into 3 groups which included gastritis group A, gastritis group B and control group. Rats in gastritis group A were fed with Hp Sydney Strain 1, the mixture of 2% aspirin and 0. 6N hydrochloric acid was fed in gastritis group B. The control group only received saline. All of the rats were killed and mucosal tissue was obtained from antrum and greater curvature of the gastric body. Pathological and Hp examination were performed in the tissue slides, and then it was stained to check PGP 9. 5, gastric body's mucosal expression of C-kit, antrium's mucosal expression of gastrin and somatostatin. The cell body, the maximum diameter (Dmax, μm), mean area( μm2) and optical density (nm), integral optical density of the gastrin and somatostatin in the C-kit expression positive neurons from the gastric wall were compared among the groups. Result The mean area and optical density of PGP 9. 5 expression in neurons from the gastric wall of rat in group A or B were obviously lower than that of the control group ( P ＜0. 01 ), while there was no difference between gastric group A and B ( P ＞0. 05). Gastric group A had higher GAS expression than control group, while SS expression was lower than control group( P＜0. 05). There was no difference between group B and the control group in the two variances( P ＞0. 05).By linear correlation analysis, it showed that SS was negatively correlated with GAS ( r = - 0. 333, P ＜0. 01 ). The distributive area and diameter of cells with C-kit expression in both group A and B were significantly smaller than that in the control group ( P ＜ 0. 05 ), while there was no obvious difference between group A and B ( P ＞ 0. 05 ). There was no difference of integral optical density of the C-kit expression positive neurons among the three groups. Conclusions Hp infection and NSAIDs might cause gastritis and had influence on the structural changes of neurons from gastric wall and ICC. Hp infection could obviously inhibit SS excretion from antrum mucosa while increase Gastrin excretion. NSAIDs induced gastritis had little influence on GAS and SS.
