Objective To evaluate safety and efficacy of EUS-FNA for occupying pancreatic lesions.Methods Data of 62 patients with occupying pancreatic lesions,who underwent EUS-FNA between June 2011 and June 2014,were analyzed for completion and complications,with surgery and clinical follow-up as the golden standard.Accuracy,sensitivity and specificity of EUS-FNA were calculated.Results A total of 62 patients with pancreatic lesions successfully underwent EUS-FNA and median puncture number was 4.2(3 to 8).Success rate of puncture was 100％ and sampling satisfaction rate was 90.3％ (56/62).No complications such as fever,infection,bleeding,perforation,severe pancreatitis or death were found.With the final diagnosis as the golden standard(39 malignant lesions and 23 benign lesions),overall diagnostic accuracy of EUS-FNA was 88.7％(55/62).The cytology diagnostic accuracy was 69.4％ (43/62),significantly higher than that of the tissue pathology of 30.6％ (19/62,P＜0.01).Sensitivity and specificity of the procedure were 87.2％(34/39) and 91.3％(21/23) respectively.Conclusion EUS-FNA is an effective and safe procedure in diagnosis of occupying pancreatic lesions.

OBJECTIVETo investigate relationship between expressions of hypoxia inducible factor-1alpha (HIF-1alpha) and insulin-like growth factor-II (IGF-II) as well as their correlation with angiogenesis and prognosis in gastric carcinoma.

METHODSHIF-1alpha and IGF-II mRNA expression were analyzed using in situ hybridization, microvessel density (MVD) was determined by anti-CD34 immunostaining in 118 cases gastric carcinoma.

RESULTSThe positive rates of HIF-1alpha mRNA and IGF-II mRNA were 49.2% and 47.4%, respectively. In stage T3-T4 cases, positive rates of HIF-1alpha and IGF-II mRNA expression, the frequencies of vessel invasion, lymph node and distant metastasis were significantly higher than those in stage T1-T2 cases. The mean MVD in stage T3-T4 tumors, vessel invasion, lymph node metastasis and distant metastasis were significantly more frequent than those in stage T1-T2 tumors. The mean MVD in tumors with positive HIF-1alpha and IGF-II mRNA expression was significantly higher than those in tumors without HIF-1alpha and IGF-II mRNA expression. The expression of HIF-1alpha was positively correlated with IGF-II mRNA. There were positive correlations between MVD and expression of HIF-1alpha and IGF-II mRNA, respectively. The mean survival time and 5-year survival rate in cases with positive HIF-1alpha and VEGF expression and MVD value >/= 41.5 were significantly shorter than those in cases with negative HIF-1alpha and VEGF expression and MVD value < 41.5.

CONCLUSIONSHIF-1alpha and IGF-II play an important role in tumor invasion and metastasis, especially in tumor angiogenesis. So test of the expression of HIF-1alpha and IGF-II may act as a useful index of treatment and prognosis.

OBJECTIVETo investigate mRNA expression of syndecan-1 and heparanase in gastric carcinoma, and their correlation with the growth-pattern, invasion, metastasis and prognosis of gastric carcinoma.

METHODSIn situ hybridization technique was used to examine mRNA expression of syndecan-1 and heparanase in 118 specimens of gastric carcinoma.

RESULTSThe positive rates of syndecan-1 mRNA and heparanase mRNA were 42.4% and 55.9%, respectively. The expression of syndecan-1 mRNA and heparanase mRNA were related to tumor invasion depth (chi(2) = 32.95, P = 0.001; chi(2) = 23.19, P = 0.001), vessel invasion (chi(2) = 46.22, P = 0.001; chi(2) = 33.78, P = 0.001), lymph node (chi(2) = 28.62, P = 0.001; chi(2) = 25.43, P = 0.001) and distant metastasis (chi(2) = 63.30, P = 0.001; chi(2) = 65.76, P = 0.001), and syndecan-1 mRNA positive expression was related to tumor size (chi(2) = 6.25, P = 0.012). There was a negative relationship between Syndecan-1 mRNA and heparanase mRNA expression (r = -0.844, P = 0.001). The mean survival time of cases with low expression of syndecan-1 mRNA was significantly shorter than that of cases with high expression (r = 36.48, P = 0.001), and meanwhile, the mean survival time of heparanase mRNA positive cases was significantly shorter than that of cases with negative expression (r = 34.41, P = 0.001).

CONCLUSIONSThe mRNA expression of syndecan-1 and heparanase can predict the invasion and metastasis of gastric carcinoma, and can be used as markers of prognosis of gastric carcinoma.

Objective To study the plasma folate concentrations in the third trimester of pregnant women and newborn babies so as to assess the association between them.Methods Pregnant women in Yuanshi and Laoting counties in Hebei province from May to June in 2009 were recruited with related information collected at enrollment.Those pregnant women being enrolled were followed up until delivery.Maternal blood was collected before delivery,and cord blood was collected after the expulsion of the placenta.Data from 437 pairs of women and newborns were analyzed.Plasma folate concentration was measured by Microbiological assay,with maternal plasma folate concentration ＜6.8 nmol/L defined as folate deficiency.Neonatal plasma folate concentration below 10％ was defined as relative deficiency.Student t-test and ANOVA were used to compare the plasma folate concentrations between the groups and x2 test was used to compare the situation of folate deficiency.In order to assess the association between maternal and newborn folate levels,logistic regression analysis was used to estimate the odds ratio of the neonatal plasma folate relative deficiency between the maternal folate deficient and normal groups after adjusting factors as age,BMI,region,career and education.Linear regression was used to test the trend by quintiles of maternal plasma folate concentration.Pearson' s test was used to test the relationship between the ratio of neonatal and maternal plasma folate level and the level of maternal plasma folate.Results The geometric mean of maternal plasma folate concentration was 8.0(95％CI:7.6-8.5) nmol/L and the deficiency was 29.3％,but in newborn babies,they were 24.0(95％CI:23.1-25.0) nmol/L and 0.9％ respectively.The plasma folate level in newborn babies was 3.0 times as high as in maternal (t=32.519,P＜0.01 )but the neonatal plasma folate deficiency status was higher than in matemal ( x2=137.2,P＜0.01 ).When compared with the normal plasma folate level group,the risk on neonatal plasma folate relative deficiency in the maternal folate deficiency group was significantly higher aiter adjusted for confounders (OR=1.96,95％CI:1.02-3.80).The neonatal plasma folate level significantly increased along with the maternal plasma folate level (Ptrend＜0.05).The ratio of neonatal and maternal plasma folate level was significantly inversely correlated with the maternal folate level (r=-0.810,P＜0.001 ).Conclusion Folate status in newborns was much better than in their mothers',in the northern rural areas of China.The maternal folate status was positively correlated with their offspring' s.Active placental transport for folate was significantly increasing when the maternal plasma folate level decreased.

OBJECTIVE To explore the hypolipidemic mechanisms of the total phenylpropanoid glycosides from Ligustrum robustum (Roxb.)Blume (LRTPG)in hamsters using proteomics technique. METHODS The hamsters were fed with a high fat diet to induce hyperlipidemia.Then LRTPG of high (1.2 g·kg-1),medium(0.6 g·kg-1)and low(0.3 g·kg-1)doses were administrated daily for 4 weeks.Then the concentrations of plasma and hepatic lipids were determined using enzymic methods.The total protein was extracted from livers of the model group and the group treated with the high dose of LRTPG for label-free quantitative proteomics. RESULTS LRTPG significantly reduced the concentrations of plasma and hepatic lipids in hamsters fed a high fat diet. The proteomics data showed that a total of 2231 proteins were identified,and 549 proteins were found to be differentially expressed between the model group and the group treated with LRTPG.Among the 549 proteins,93 proteins were up-regulated and 59 proteins were down-regulated, and 397 proteins were absent or not. And some of these proteins were much related to the lipid metabolism. Further, gene ontology (GO) analysis indicated metabolic process, transport, oxidation-reduction process, phosphorylation, signal transduction, lipid metabolic process were the main biological processes that those differentially expressed proteins participated. KEGG pathway analysis showed that those proteins were involved in several metabolic pathways including oxidative phosphorylation,non-alcoholic fatty liver disease(NAFLD),PI3K-Akt signaling pathway, cAMP signaling pathway, cGMP-PKG signaling pathway. CONCLUSION The proteomics study could provide valuable clues to help us to understand the hypolipidemic mechanisms of LRTPG much better.

Objective The aim of this study was to analyze the status and influencing factors of public health service utilization in rural patients with severe mental illness in Yunnan province. Methods The main caregivers of patients with severe mental illness in Yunnan province were selected by stratified cluster sampling method. Multivariate logistic regression was used to analyze the influencing factors of public health service utilization. Results A total of 284 cases of rural patients with severe mental illness were investigated, including 144 males (50.7％) and 140 females (49.3％) . The rate of medical file filing, follow-up rate of village doctor, participation rate of free physical examination and health education acceptance rate among patients with severe mental illness were 89.8％, 84.9％, 73.2％and 56.7％respectively (<0.05) . Female patients had higher participation rate of free physical examination than male patients, and patients having work and patients with controlled disease condition and their caregivers had higher rates of health education acceptance rate than their counterparts ( <0.05) . Conclusion Measures should be taken to strengthen the work of medical examination for male patients, and to expand health education activities for patients having no work and patients with uncontrolled disease condition, so as to improve the public health service utilization in rural areas of Yunnan province.

Identification accuracy of traditional Chinese medicine is crucial for the traditional Chinese medicine research, production and application. DNA barcoding based on the mitochondrial gene coding for cytochrome c oxidase subunit I (COI), are more and more used for identification of traditional Chinese medicine. Using universal barcoding primers to sequence, we discussed the feasibility of DNA barcoding method for identification commonly-used medicinal snakes (a total of 109 samples belonging to 19 species 15 genera 6 families). The phylogenetic trees using Neighbor-joining were constructed. The results indicated that the mean content of G + C(46.5%) was lower than that of A + T (53.5%). As calculated by Kimera-2-parameter model, the mean intraspecies genetic distance of Trimeresurus albolabris, Ptyas dhumnades and Lycodon rufozonatus was greater than 2%. Further phylogenetic relationship results suggested that identification of one sample of T. albolabris was erroneous. The identification of some samples of P. dhumnades was also not correct, namely originally P. korros was identified as P. dhumnades. Factors influence on intraspecific genetic distance difference of L. rufozonatus need to be studied further. Therefore, DNA barcoding for identification of medicinal snakes is feasible, and greatly complements the morphological classification method. It is necessary to further study in identification of traditional Chinese medicine.

OBJECTIVETo compare the differences in the efficacy on distant version of naked eye in the patients of juvenile myopia between rotating manipulation and lifting-thrusting manipulation of acupuncture.

METHODSOne hundred and twenty cases (240 eyes) were randomized into a rotating manipulation group and a lifting-thrusting manipulation group, 60 cases (120 eyes) in each group. Additionally, a corrective lenses group, 60 cases (120 eyes), was set up as the control. In both manipulation groups, Cuanzhu (BL 2),Yuyao (EX-HN 4), Sizhukong (TE 23), Taiyang (EX-HN 5), Fengchi (GB 20), Zusanli (ST 36), Guangming (GB 37) and Sanyinjiao (SP 6) were punctured, but stimulated with rotating manipulation and lifting-thrusting manipulation respectively three times per week, 10 times as a treatment session and totally one session was required. In the corrective lenses group, the glasses were applied at daytime. The clinical efficacy and the changes in distant vision of naked eye before and after treatment were compared among the three groups.

RESULTSThe total effective rate was 87.5% (105/120) in the rotating manipulation group, which was better than 69.2% (83/120) in the lifting-thrusting manipulation group (P < 0.05). The distant vision of naked eye was improved apparently in the rotating manipulation group and the lifting-thrusting manipulation group after treatment (both P < 0.05). But it was not improved in the corrective lenses group (P > 0.05). The distant vision of naked eye was improved more apparently after treatment in the rotating manipulation group as compared with that in the lifting-thrusting manipulation group (0.75 +/- 0.23 vs 0.68 +/- 0.24, P < 0.05). For 96 cases (192 eyes) with acupuncture treatment, in 3-month follow-up, 87.0% (167/192) of the cases maintained the stable vision as the original level and 13.0% (25/192) of them were reduced in the vision In the acupuncture groups, it was found that the improvement of distant vision of naked eye was more obvious after treatment with younger age, better basic vision and shorter duration of sickness (all P < 0.05).

CONCLUSIONAcupuncture achieves the positive and sustainable clinical effect on juvenile myopia, and the results of rotating manipulation are superior to that of lifting-thrusting manipulation. Age, basic vision and duration of sickness impact the clinical efficacy.

OBJECTIVETo summarize the clinical characteristic and outcome of digital gigantism of the foot.

METHODSRetrospectively analyze the clinical documents of cases of digital gigantism of the foot. Twelve 12 cases with 13 feet in this study included 8 male and 4 female with an average 4.6-years-old. All the deformities were found at birth. Multiple toes involved were more than single toe, and tibial toe involved more than fibular. Forefoot was enlarged. All the phalanges involved and partial metatarsal bones were enlarged. Marked increase in subcutaneous fat was found in all cases in the operation which infiltrated interossei and articular capsules. The appearance of the nerves and its branches in the foot were normal and fat infiltrating was not discovered. The operation types included debulking, epiphyseal arrest, amputation, nerve stripping and anastomosis.

RESULTSSeven cases were followed up with mean periods 25.6 months. Functional evaluation according to a criterion formulated by author revealed a result of 2 excellent, 2 good and 3 fair.

CONCLUSIONSDigital gigantism of the foot is an uncommon congenital deformity of the foot characterized by overgrowth of both the soft-tissue and the osseous elements of the enlarged toe and forefoot. Surgical treatment is the unique method, and the goal is to reduce the size of the foot to allow fitting regular shoes and walking readily. There are several types of operations which to be chosen. The indication, the timing of operative intervention and the selection of operation type should be paid more attention.

Objective:To investigate the epidemiological characteristics of human coronavirus (HCoV) in hospitalized children with respiratory tract infection in Hebei region, providing evidence for the diagnosis and prevention of children with respiratory tract infection.Methods:A retrospective study was conducted on 1 062 HCoV positive children hospitalized for respiratory tract infection in Children′s Hospital of Hebei Province from January 2015 to December 2020, aged from 33 days to 14 years, with a median age of 2 years. 27 932 (60.9%) were males and 17 944(39.1%) were females. And the gender, ages, seasonal distribution, HCoV-positive rates, co-detection distribution and clinical diagnosis of HCoV positive cases were analyzed by SPSS 25.0. Enumeration data were expressed by frequency and percentage; categorical variable were compared by the Pearson χ 2test. Results:The overall HCoV-positive rate was 2.31% (1 062/45 876), which was 2.37% (662/27 932) in male children and 2.23% (400/17 944) in female children. There was no statistically significant difference between genders (χ2=0.916, P=0.339). Children at age groups<1 years (2.44%) and 1-<3 years (2.63%) had higher HCoV-positive rates than those at age groups 3-<5 years (1.97%) and ≥5 years (1.38%) (χ2=27.332, P<0.01). The HCoV-positive rates from 2015 to 2018 were 2.13%, 2.45%, 2.28% and 2.23%. The HCoV-positive rate of 2019 (1.71%) was significantly lower than in 2016 (χ2=12.05, P<0.01), 2017 (χ2=7.34, P=0.01) and 2018 (χ2=6.78, P=0.01), but there was no significant difference compared with 2015 (χ2=2.84, P=0.09). The HCoV-positive rate of 2020 (3.37%) was significantly higher than in 2015 (χ2=13.636, P<0.01), 2016 (χ2=11.099, P<0.01), 2017 (χ2=15.482, P<0.01), 2018(χ2=18.601, P<0.01) and 2019(χ2=45.580, P<0.01). The positive rate was highest in spring (March to May) in 2015 and 2017 to 2018. February to April and July to September of 2016 were the peak periods of positive detection. No obvious seasonal change was observed in 2019 and the HCoV-positive rate of 2020 was extremely low from January to July, following significantly increased from August to December. 26.37% (280/1 062) of HCoV were co-detected with other respiratory pathogens and the most frequently identified mixed detection was RSV. Three or more pathogens were detected in 7.34% (78/1 062) of the HCoV-positive samples. Bronchopneumonia and bronchiolitis were more frequently observed in the single HCoV positive (61.89% and 16.75%) children compared to co-detected children(34.29% and 9.64%)(χ2=63.394 and 8.228, P<0.01). However, compared to those with HCoV mono-detection, co-detected children were more likely to have severe pneumonia (4.6% and 47.14%) (χ2=280.171, P<0.01). Conclusions:HCoV is one of the respiratory pathogens in children in Hebei region and more prevalent in spring. The susceptible population of HCoV is mainly children under the age of 3 years old. HCoV often co-detects with other respiratory pathogens, and the co-infection is one of the risk factors of severe pneumonia in children with respiratory infection.
