Objective To analyze the prevalence and influencing factors of anxiety and depression among pregnant women in Jianyang City. Methods Convenience sampling method was used to select 322 pregnant women in Jianyang Maternal and Child Health Hospital of Jianyang City. The depression and anxiety of the participants were measured with self-rating anxiety scale(SAS) and self-rating depression scale(SDS)，and the degree of social support was measured with social support rating scale (SSRS). Pearson correlation analysis was used to analyze the relationship between anxiety, depression and social support. The chi square ( 2) test and the non-conditional Logistic regression model were used to analyze the influencing factors of anxiety and depression. Results Anxiety rate and depression rate of pregnant women in Jianyang city were 5.3% and 5.6% respectively. There was a negative correlation between anxiety, depression and social support (P<0.05). Absence of prenatal examination (OR=4.554, 95% CI: 1.063-19.510) was a risk factor for anxiety among pregnant women in Jianyang City. Late pregnancy (OR=5.381, 95% CI: 1.422-20.363) and medium degree of social support (OR=4.150, 95% CI: 1.198-14.375) were risk factors for depression among pregnant women in Jianyang City. Junior high school (OR=0.015, 95% CI: 0.001-0.275), high school or technical secondary school (OR=0.004, 95% CI: 0.001-0.128), junior college or above (OR=0.053, 95% CI: 0.003-0.851) were protective factors for depression. Conclusions The prevelance of anxiety and depression in pregnant women cannot be ignored. It is important to carry out mental health intervention according to the above factors.

Objective To observe changes in the infrared thermogram of Yangming meridian acupoints in patients with idiopathic facial paralysis in acute stage. Method High-performance uncooled infrared focal plane array (M7800 Thermal Imager, LumaSense, USA) was used to detect the infrared thermogram of Yangming meridian acupoints[Kouheliao (LI19), Yingxiang (LI20), Hegu (LI4), Shangyang (LI1), Chengqi (ST1), Sibai (ST2), Juliao (ST3), Dicang (ST4), Daying (ST5), Jiache (ST6), Xiaguan (ST7), Tianshu (ST25), and Zusanli (ST36) ]of 80 patients with idiopathic facial paralysis in acute stage and 75 healthy subjects. The temperature data of the meridian acupoints obtained from the analysis software were statistically processed. Result Compared with the healthy subjects, the temperature differencesΔT of the Hand Yangming Meridian acupoints including Kouheliao, Yingxiang and Hegu, and Foot Yangming Meridian acupoints including Chengqi, Sibai, Juliao, Dicang, Daying, Jiache and Xiaguan were more significant in the patients with idiopathic facial paralysis in acute stage, and the differences were statistically significant (P<0.05); the temperature differences ΔT of the Hand Yangming Meridian acupoint Shangyang, and the Foot Yangming Meridian acupoints including Tianshu and Zusanli in the facial paralysis patients showed insignificant differences compared with those in the healthy subjects (P>0.05). Conclusion There are changes in the infrared thermogram at Yangming meridian acupoints located on face (Kouheliao, Yingxiang, Shangyang, Chengqi, Sibai, Juliao, Dicang, Daying, Jiache and Xiaguan) and the distant acupoint Hegu in idiopathic facial paralysis patients in acute stage, while Shangyang, Tianshu and Zusanli do not present the above phenomenon, indicating the specificity of acupoint effect from the perspective of infrared.

Objective To observe the change of functional connectivity(FC) between default mode network (DMN) and the other brain regions in patients with depression before and after magnetic seizure therapy(MST),and explore the role of DMN in therapeutic mechanism of MST.Methods Fifteen patients with depression who met the criteria of enrollment underwent rs-fMRI scanning before and after the MST treatmerts.As a very important region of DMN,the posterior cingulate cortex(PCC) was selected as the region of interest(ROI)to make the functional connectivity analysis with other brain regions,then the differences in FC before and after MST treatments were tested.The correlation of FC index changes with the score changes of HAMD-17 and five factors of HAMD-17 was analyzed after MST treatments.Results A comparison of the differences in DMN before and after treatments showed that the connection between left PCC and bilateral medial temporal lobe connectivity decreased significantly (left:MNI:x,y,z =-66,-39,-15,right:MNI:x,y,z =69,-30,-6) (P＜ 0.05).The connection between left PCC with left cerebellum (MNI:x,y,z =-33,-42,-42) and left occipital lobe(MNI:x,y,z=0,-84,24)significantly increased(P＜0.05).The changes of sleep factor of HAMD-17 were positively correlated with the functional connectivity changes of bilateral medial temporal lobe (left:r=0.670,P=0.006;right:r=0.570,P=0.026),but negatively correlated with the functional connectivity changes of the left cerebellum (r=-0.543,P=0.037).Conclusion MST can play an antidepressant role by regulating DMN functional connection of depressive patients and it may be a neuromodulation mechanism of MST in the treatment of depression.

Objective To explore the clinical factors that can be used to predict the early weight loss after laparoscopic sleeve gastrectomy(LSG).Methods The clinical data of 64 obese patients undergoing LSG in Peking Union Medical College Hospital from August 2015 to January 2018 were retrospectively analyzed.We analyzed the relationship between different clinical factors and early weight loss,determined the independent predictors based on models,and estimated their test power by using the receiver operating characteristic(ROC)curves.Results Correlation analysis indicated that preoperative body mass index(=0.000,=0.000,=0.000),waist circumference(WC)(=0.000,=0.000,=0.000),whole body fat volume(=0.000,=0.006,=0.003),homeostatic model assessment for insulin resistance(HOMA-IR)(=0.000,=0.000,=0.002),and hypersensitive C-reactive protein(hsCRP)(=0.004,=0.002,=0.025)were negatively correlated with excess weight loss percentage(EWL %) after 3,6 and 12 months.Also,hsCRP after 6 months showed negative correlation with EWL % after 1 year(=0.029).Binary Logistic regression analysis showed that WC was an independent predictor of early weight loss(=0.018).ROC analysis showed that when the optimal cutoff value is 142.5 cm for WC, index was highest,with a sensitivity of 80% and a specificity of 87%.Patients were further divided into low WC group and high WC group based on this optimal cutoff value.The low WC group had significantly higher EWL% than the high WC group 3 months(=6.677,=0.000),6 months(=6.157,=0.000),and 1 year(=4.006,=0.000)after surgery.The low WC group also had significantly lower hsCRP than high WC group 6 months after surgery(=-3.510,=0.000).HOMA-IR showed no significant difference between these two groups(=-0.821,=0.412).Conclusions WC is an independent predictor of weight loss early after LSG.The patients with low WC have better weight loss effectiveness.

Identifying data-driven biotypes of major depressive disorder (MDD) has promise for the clarification of diagnostic heterogeneity. However, few studies have focused on white-matter abnormalities for MDD subtyping. This study included 116 patients with MDD and 118 demographically-matched healthy controls assessed by diffusion tensor imaging and neurocognitive evaluation. Hierarchical clustering was applied to the major fiber tracts, in conjunction with tract-based spatial statistics, to reveal white-matter alterations associated with MDD. Clinical and neurocognitive differences were compared between identified subgroups and healthy controls. With fractional anisotropy extracted from 20 fiber tracts, cluster analysis revealed 3 subgroups based on the patterns of abnormalities. Patients in each subgroup versus healthy controls showed a stepwise pattern of white-matter alterations as follows: subgroup 1 (25.9% of patient sample), widespread white-matter disruption; subgroup 2 (43.1% of patient sample), intermediate and more localized abnormalities in aspects of the corpus callosum and left cingulate; and subgroup 3 (31.0% of patient sample), possible mild alterations, but no statistically significant tract disruption after controlling for family-wise error. The neurocognitive impairment in each subgroup accompanied the white-matter alterations: subgroup 1, deficits in sustained attention and delayed memory; subgroup 2, dysfunction in delayed memory; and subgroup 3, no significant deficits. Three subtypes of white-matter abnormality exist in individuals with major depression, those having widespread abnormalities suffering more neurocognitive impairments, which may provide evidence for parsing the heterogeneity of the disorder and help optimize type-specific treatment approaches.

Objective To evaluate the quality of life in pregnant women with hepatitis B positive and to explore its influencing factors. Methods Eighty pregnant women with positive hepatitis B were randomly selected from Jan. to Apr. 2018 in Jianyang Maternal and Child Health Hospital as the case group, and 323 normal pregnant women were selected as the control group. A face-to-face survey was conducted using the Concise Health Survey Scale SF-36. t test, ANOVA and multiple linear regression were used for statistical analysis. Results The scores of PF and RP in the case group were lower than those in the control group, and the scores of GH in the case group were higher than those in the control group. Analysis of the factors affecting the quality of life of the case group found that the more severe the early pregnancy reaction, the lower the quality of life score. Conclusions The PF and RP of pregnant women with hepatitis B positive in Jianyang City are worse than those of normal pregnant women. Comprehensive measures should be taken to improve their quality of life.

OBJECTIVE: The purpose of this study was to assess the association between triglycerides (TG), total cholesterol (TC) at baseline, and type 2 diabetes mellitus (T2DM) incidence in a general Chinese population. Further, it aimed to evaluate the ability of TG and TC to predict T2DM incidence. METHODS: Qingdao Diabetes Prevention Program participants recruited between 2006 and 2009 were followed up in 2012-2015. TG, TC, and T2DM status were measured. Cox proportional hazards models were used to estimate the association between TG, TC, and T2DM incidence. The receiver operating characteristic (ROC) curve was used to evaluate the ability of TG and TC to identify T2DM participants. RESULTS: The incidence of T2DM significantly increased with TG in women and TC in both men and women (Ptrend < 0.05). Univariate Cox regression indicated that higher TG {borderline high TG [hazards ratio (HR): 2.05; 95% confidence interval (CI): 1.40, 3.00] and hypertriglyceridemia [HR: 2.64; 95% CI: 1.68, 4.15]} and TC [hypercholesterolemia (HR: 2.05; 95% CI: 1.43, 2.95)] were significantly associated with increased risk of T2DM incidence in women but not in men. Multivariate Cox regression showed that hypertriglyceridemia in women (HR: 1.78, 95% CI: 1.07, 2.97), borderline high TC in men (HR: 1.61, 95% CI: 1.04, 2.48), and hypercholesterolemia in women (HR: 1.68, 95% CI: 1.81, 2.61) had a higher significant risk of T2DM incidence. The optimal cutoff values of TG were > 1.15 and > 1.23 mmol/L in men and women, respectively. For TC, they were > 5.17 and > 5.77 mmol/L in men and women, respectively. The area under the ROCs of TG and TC were 0.54 (0.51-0.57) and 0.55 (0.52-0.58), respectively, in men, and 0.60 (0.58-0.62) and 0.59 (0.56-0.61), respectively, in women. CONCLUSION Elevated TG and TC were risk factors for T2DM incidence. However, no predictive capacity was found for both factors to identify T2DM incidence in Chinese men and women. Hence, TG and TC levels in both Chinese men and women might be used for decreasing the incidence of T2DM but no clinical predictive capacity for T2DM.

To investigate the value of diffusion-weighted imaging(DWI)and apparent diffusion coefficient(ADC)in the diagnosis and differential diagnosis of posterior fossa solid hemangioblastoma(PFSH). We retrospectively analyzed the clinical data of 15 PFSH patients and 58 patients with other hypervascular tumors in the posterior fossa(the latter included 23 cases of meningioma,5 cases of medulloblastoma,8 cases of acoustic neuroma,4 cases of hemangiopericytoma,5 cases of lymphoma,9 cases of metastatic tumor,3 cases of astrocytoma,and 1 case of choroid plexus papilloma)confirmed by operation and pathology.All patients underwent axial DWI scans,and the mean ADC value of solid part of the tumors and the adjacent normal cerebellar white matter were measured,and then the normalized ADC was calculated.In addition, test was used to compare the differences in mean ADC and normalized ADC between these two groups,and receiver operating characteristic(ROC)curve was applied to analyze the diagnostic performance of normalized ADC. Of all the 15 PFSH patients,DWI appeared hypointense in 12 patients and isointense in 3 patients;the signals on ADC maps were isointense or hyperintense;the mean ADC value of PFSHs was(1.881±0.445)×10 mm /s and the normalized ADC was 2.70±0.62.In contrast,in 58 patients with other tumors in the posterior fossa,DWI appeared hyperintense in 51 cases,isointense in 3 cases,and hypointense in 4 cases;the mean ADC value was(0.771±0.202)×10 mm /s,and the normalized ADC was 1.17±0.33.Thus,the ADC value and normalized ADC value were significantly higher in PFSH than in other tumors in the posterior fossa(=9.419,<0.001;=9.184,<0.001).The cut-off value of the normalized ADC for the diagnosis of solid hemangioblastoma was 1.89,with the sensitivity and specificity being 100%and 96.6%respectively,and the area under the ROC curve was 0.989. ADC and normalized ADC are valuable in the differential diagnosis of PFSH from other tumors with abundant blood supply.

Objective: To examine the effectiveness of non-operative of colonic fistula following acute pancreatitis. Methods: Retrospective analysis of 354 patients with acute pancreatitis who were admitted to Department of Hepatobiliary Surgery of Chinese People′s Liberation Army General Hospital from January 2013 to December 2018. Age of the patients was (46±14) years (range: 14-85 years); 249 cases (70.3%) were males. There were 41 cases of acute edematous pancreatitis and 313 cases of acute necrotising pancreatitis. Two hundred and fifteen cases were diagnosed as moderate severe acute pancreatitis and 139 were diagnosed as severe acute pancreatitis. Among 313 cases of acute necrotising pancreatitis, 62 cases underwent non-surgical treatment, 251 cases underwent surgical treatment in which 218 of minimal access retroperitoneal pancreatic necrosectomy underwent percutaneous nephroliguectomy with peripancreatic necrotic tissue removal technique. Results: There were 15 cases of colon fistula following acute necrotising pancreatitis, and the incidence rate was 4.2%(15/354). There were 7 males and 8 females, with age of (39±8) years (range: 27 to 50 years). The median interval between acute pancreatitis onset and diagnosis of colonic fistula was 71 days(27-134) days. Two cases occurred at the hepatic flexure of the colon, 4 cases at transverse colon, and 9 cases at splenic flexure of colon. Of the 354 patients, 39 cases died and the mortality was 11.0%. Two patients underwent laparotomy, and one of them died. The remaining 13 patients underwent non-surgical treatment and were discharged. Conclusion Acute pancreatitis with colonic fistula can be treated with non-surgical treatment and can achieve good prognosis.

BACKGROUND:Due to limited sources,poor hemocompatibility and poor anticoagulation performance,small-diameter tissue-engineered blood vessels cannot be applied in clinical practice.OBJECTIVE:To explore the physicochemical and mechanical properties of sheep carotid arteries after the decellularization in order to find appropriate materials for the preparation of tissue-engineered blood vessels.METHODS:Fresh carotid arteries from sheep were randomly divided into two groups:control group,in which,the sheep carotid arteries were cryopreserved for use after trimming and cleaning;experimental group,in which,after trimming and cleaning,the carotid arteries were decallularized by Triton X-100.sodium deoxycholate and EDTA for 24 hours,rinsed for 72 hours,digested with RNA/DNA enzymes for 24 hours,rinsed for 24 hours and reserved for later use.In both groups,blood samples were subjected to hematoxylin-eosin staining,collagen fiber staining,elastic fiber dyeing,and electron microscopy observation.The physical and chemical properties of the blood vessels are tested by tensile strength,wall tension and thickness.RESULTS AND CONCLUSION:(1) The collagen fibers in both two groups were neat and compact in alignment,with no obvious fracture.(2) Hematoxylin-eosin staining showed that:in the control group,the nuclei were distributed in the inner membrane,middle lamella and outer membrane of the vessels,and the fibers ran regularly;in the experimental group,the fibers ran in order but loosely,and there were no nuclei in the inner membrane,middle lamella and outer membrane of the vessels.(3) Elastic fibers in the control group were regular in alignment and mainly distributed in the middle lamella and outer membrane of the vessels,while in the experimental group,the elastic fibers ran regularly but loosely,and mainly distributed in the middle lamella and outer membrane of the vessels.(4) Under the scanning electron microscope,the originally formed vessels were observed in the experimental group,with no cell residues,and the collagen fibers ran orderly with no fracture and with uniform pore structure.(5) The vessel thickness was lower in the experimental group than the control group (P ＜ 0.01),but the tensile strength showed no difference between the two groups,which was 46.55 kPa in the two groups.To conclude,the decelluarized sheep carotid artery can retain the necessary mechanical properties of the blood vessels after achieving the maximum removal of antigenicity.
