Abstract
The low susceptibility to mastitis of female donkey (jenny) mammary glands and the strong immune properties of donkey milk are acknowledged, but little is known about the genes involved in mammary gland immunity in jennies. Herein, we used RNA-sequencing and bioinformatics analyses to explore jenny mammary gland transcriptomes and detect potential functional differentially expressed (DE) mRNAs related to immunity during four specific developmental stages: foetal (F), pubertal (P), adult parous nonlactation (N) and lactation (L). A total of 2497, 583 and 1820 DE mRNAs were identified in jenny mammary glands at F vs. P, P vs. N, and N vs. L, respectively. Gene Ontology (GO) and Kyoto Encyclopedia of Gene and Genomes (KEGG) analyses revealed numerous GO terms related to immune function, especially between F and P. Seven significantly enriched profiles were identified, among which 497 and 1261 DE mRNAs were upregulated in profiles 19 and 17. Eleven mRNAs were enriched in over 10 KEGG pathways. β-2-microglobulin (B2M), immunoglobulin heavy constant mu (IGHM), toll like receptor 2 (TLR2), toll like receptor 4 (TLR4) and myeloid differentiation factor 88 (MYD88) were mainly involved in phosphoinositide 3-kinase (PI3K)-Akt signalling, phagosome and nuclear factor kappa-B (NF-kappa B) signalling pathways. The findings provide insight into the molecular features underpinning the low prevalence of intramammary infections (i.e., mastitis) in donkeys.

Abstract
Objective: To investigate the effects of RNA m6A demethylase ALKBH5 gene deficiency on cerebellar morphology and function in the aged mice, and to explore the role of ALKBH5 in cerebellar degeneration. Methods: Western blot was performed to detect the protein level of ALKBH5 in the cerebellum of wild-type mice of various ages. The expression of NeuN, Calbindin-D28K, MAP2, GFAP and other proteins in the cerebella of middle-aged (12-month-old) and aged (18-month-old) wild-type mice and ALKBH5-/- mice was examined using immunohistochemistry. The balance beam test and gait analysis were performed to test the balance ability and motor coordination of the mice. Results: With aging of the mice, the expression of ALKBH5 in the cerebellum increased gradually in an age-dependent manner. In the aged mice, but not middle-aged mice, the body weight, whole brain weight and cerebellum weight of ALKBH5-/- mice decreased by 15%, 10% and 21%, respectively (P<0.05). The expression of ALKBH5 in the Purkinje cells was much higher than that in other types of neural cells. Correspondingly, ALKBH5-deficiency caused 40% reduction in the number of Purkinje cells, as well as the length and density of neuronal dendrites in the aged mice (P<0.01). In addition, the time for the aged ALKBH5-/- mice to pass the balance beam was 70% longer than that of the wild type mice of the same age, with unstable gaits (P<0.01). Conclusions: Gene deficiency of RNA m6A demethylase ALKBH5 causes cerebellar atrophy, Purkinje neuron loss and damage in the aged mice. These changes eventually affect mice's motor coordination and balance ability. These results suggest that imbalanced RNA m6A methylation may lead to neurodegenerative lesions in the cerebellum of mice.

Abstract
PURPOSE Gross extrathyroidal extension (gETE) into major vessel is considered the most advanced stage of the locally advanced papillary thyroid cancer (PTC). Surgical intervention may not benefit some patients at this disease stage or even result in intraoperative death due to massive hemorrhage; however, it is still considered an effective strategy for most cases. The lack of description for this challenging invasion in PTC warrants detailed characterization of its pattern, risk factors, optimal surgical method, and prognostic value. METHODS In total, 3127 patients diagnosed as having PTC were enrolled and categorized into two the following groups, namely the major vessel invasion (MVI) group (n = 30) and the control group (n = 3097). Data regarding clinicopathological and demographic characteristics, vascular invasion sites, postoperative complications, locoregional recurrence, distant metastasis, and surgical strategies were collected. Predictive disease-free survival (DFS) was also compared between the two groups. RESULTS MVI was independently associated with invasion of the esophageal extension, age < 55 years, tumor size > 1 cm, lateral lymph node metastasis, and distant metastasis (P = 0.00; P = 0.01; 0.05; P = 0.00; P = 0.00, respectively). The difference in the predictive DFS between the two groups was significant (P = 0.00), and the difference remained significant even in patients with ETE when compared with patients without ETE (P = 0.00). Additionally, predictive DFS did not differ significantly between patients who received vessel repairment and those who received vessel resection (P = 0.28). CONCLUSIONS This study first characterized the gross MVI pattern exhibited by PTC and the risk factors for MVI. Additionally, it demonstrated the DFS of patients with PTC. Extensive gross MVI significantly worsened the biological characteristics of PTC. Regardless of the high risk and difficulty of the operation, patients still benefited from the surgical intervention, and vessel repairment may be the optimal surgical strategy.

Abstract
OBJECTIVE Patients with advanced tumors often suffer from spinal metastatic tumor pain. The current drugs are less effective and have side effects. The objective was to explore the efficacy of iodine-125 particle implantation in the treatment of bone metastatic tumor pain. PATIENTS AND METHODS In a retrospective study, a total of 27 patients with bone metastatic tumors who could not receive surgery or radiotherapy and chemotherapy were analyzed. All patients received conventional treatment, with the visual analog scale (VAS) of >3 points, and the daily onset pain of >3 times. All patients received CT-guided iodine-125 particle implantation to treat local painful lesions. VAS scores were recorded before treatment (T0) and 1 day (T1), 7 days (T2), 30 days (T3), 90 days (T4), and 180 days (T5) after treatment. Kaplan-Meier analytical method was used to calculate the local control rate (LCR) and survival rate (SR). RESULTS All patients successfully completed the CT-guided iodine-125 particle implantation. There was no significant difference in VAS scores before and 1 day after surgery. However, compared with pre-operation, the VAS scores decreased at 7, 30, 90, and 180 days after surgery. The postoperative follow-up was 6-38 months, with a median of 16 months; the LCR at 1, 2, and 3 years after the follow-up were 87%, 51%, and 21%, respectively, and the SR was 84%, 43%, and 16%, respectively. Moreover, no serious adverse reactions were observed. CONCLUSIONS Iodine-125 particle implantation was effective in the treatment of bone metastatic tumor pain without serious complications, and hence, can be used clinically.

Abstract
BACKGROUND Infections are one of the most common causes of morbidity and mortality in patients with systemic lupus erythematosus (SLE). SLE patients have a higher risk of tuberculosis (TB) infection due to impaired immune defence. OBJECTIVES To investigate the demographics, clinical characteristics and outcomes of patients with SLE and concomitant TB. METHODS Medical records of SLE patients with TB who were admitted to Peking Union Medical College (PUMC) Hospital in 1983-2019 were retrospectively reviewed. Age- and sex-matched SLE inpatients without TB were randomly selected as controls. Clinical and laboratory features and treatment were analysed and compared, and subjects were followed up to assess their outcome. RESULTS Of the 10 469 SLE inpatients, 249 (2.4%) were diagnosed with TB. Compared with controls, SLE/TB + patients exhibited higher frequency of prior haematologic, mucocutaneous and musculoskeletal system involvement, and prior treatment with potent glucocorticoid/immunosuppressive agents (GC/ISA). Arthritis and alopecia, positive T-SPOT.TB test and lymphocytopenia were more common in SLE/TB + patients. SLE/TB + patients with lupus before TB (SLE → TB) had higher risk of miliary TB (22.8%) and intracranial TB (16.5%) than SLE/TB + patients with lupus after TB (TB → SLE). SLE/TB + patients exhibited shorter long-term survival than SLE/TB- patients; those with poorer in-hospital outcomes had more severe lymphocytopenia and had received less treatment with ISAs. CONCLUSION Systemic lupus erythematosus patients treated vigorously with GC/ISA should be alerted of increased risk of TB infection, especially miliary and intracranial TB. Positive T-SPOT.TB and lymphocytopenia served as discriminatory variables between SLE/TB + and SLE/TB- patients. Lymphocytopenia was associated with poorer outcomes in SLE/TB + patients.

Abstract
OBJECTIVE To assess the effectiveness and safety of treatment consisting of extending chemotherapy (ECT) with capecitabine following capecitabine plus oxaliplatin (CAPOX) chemotherapy for stage 3 gastric carcinoma (GC) after D2 gastrectomy. PATIENTS AND METHODS In this retrospective study, we included 214 patients with stage 3 GC who underwent D2 gastrectomy between January 2012 and April 2014. The CAPOX regimen chemotherapy was administrated to all of the patients as adjuvant therapy. The CAPOX regimen consisted of capecitabine (1000 mg/m2, in 2 divided doses for 14 d) and oxaliplatin (130 mg/m2 given on Day 1), repeated every 21 d for 8 cycles. Following CAPOX chemotherapy, 102 of these patients received extending chemotherapy (the ECT group) with capecitabine, whereas 112 patients (the control group) received no ECT. The ECT consisted of capecitabine (1000 mg/m2, in 2 divided doses for 14 d), repeated every 21 d for 8 cycles at most. The chemotherapy was discontinued if unacceptable toxicity or disease progression occurred or upon the request of the patient. All cases were followed up, and overall survival (OS), recurrence-free survival (RFS), and toxicities were compared. RESULTS The ECT group exhibited a distinctly higher 5-year OS (p=0.0468) and RFS (p=0.0483) than those of the control group. The incidence of hand-foot syndrome was markedly greater in the ECT group (p=0.0043). No toxicity-related death occurred. CONCLUSIONS Extending chemotherapy with capecitabine following the CAPOX regimen chemotherapy provides significant survival benefit for stage 3 GC after D2 gastrectomy.

Abstract
Objective: To examine the correlation factors of contralateral central lymph node metastasis in unilateral papillary thyroid carcinoma with lateral cervical lymph node metastasis. Methods: The clinical data of patients with unilateral papillary thyroid carcinoma who underwent total thyroidectomy and bilateral central lymph node dissection and ipsilateral cervical lymph node dissection from June 2016 to June 2018 at Department of Thyroid Surgery, West China Hospital, Sichuan University were analyzed retrospectively. A total of 317 patients, including 87 males and 230 females, aged (41.4±12.1) years (range: 16 to 75 years), were enrolled in this study. The risk factors of contralateral central lymph node metastasis were analyzed by χ2 test and Spearman correlation analysis. Results: There were 116, 69, 269, and 181 cases of pretracheal lymph node, prelaryngeal lymph node, ipsilateral central lymph node and contralateral central lymph node metastasis, respectively, and 16 cases of skipping metastasis. Univariate analysis showed that contralateral central lymph node metastasis was associated with gender, maximum tumor diameter, capsule invasion, pretracheal lymph node metastasis, prelaryngeal lymph node metastasis, and ipsilateral central lymph node metastasis (all P<0.05). Spearman correlation analysis showed that male (rs=0.162, P=0.004), maximum tumor diameter>10 mm (rs=0.184, P=0.001), capsule invasion (rs=0.135, P=0.016), pretracheal lymph node metastasis (rs=0.394, P<0.01), prelaryngeal lymph node metastasis (rs=0.272, P<0.01) and ipsilateral central lymph node metastasis (rs=0.203, P<0.01) were independent correlation factors for contralateral central lymph node metastasis. Conclusion: For patients with unilateral papillary thyroid carcinoma with ipsilateral cervical lymph node metastasis, bilateral central lymph node dissection should be considered if male, tumor diameter>10 mm, capsule invasion, pretracheal lymph node metastasis, prelaryngeal lymph node metastasis, or ipsilateral central lymph node metastasis.

Abstract
Objective: To preliminarily establish the multidisciplinary cooperative vaccination management model for pediatric patients with hematological and oncological diseases, and to explore its feasibility. Methods: In this prospective study a total of 150 children with hematological and oncological diseases visited immunization clinic of Shanghai Children's Medical Center from March 2017 to August 2018 were enrolled in this study. After establishing the multidisciplinary team, designing vaccination plan, staff training, implementation and quality control, a multidisciplinary immunization clinic was set up and the vaccination plan were implemented. The implementation rate of vaccination immunization, the HBsAb level and serum hepatitis B surface antibody (HBsAb) level before and after treatment, the HBsAb level and serum immunoglobulin G antibody (IgG) levels of measles, mumps, rubella (MMR) before and 6 months after immunization, the vaccine-related adverse reactions were assessed prospectively. Chi-square test or Fisher exact test was used to compare the differences of antibody level. Results: A total of 124 cases had been vaccinated as planned, with a coverage rate of 82.7%. Among these cases, the difference of HBsAb positive rate before and after treatment was significant (62.9% (78/124) vs.13.7% (17/124), χ²= 63.489, P<0.01). In 64 cases that completed three doses of hepatitis B immunization, there was a significant difference in HBsAb positive rate before and 6 months after immunization (6.3% (4/64) vs. 98.4% (63/64), P<0.01). In 40 cases that completed MMR immunization, the IgG antibody positive rate for measles (22.5% (9/40) vs. 82.5% (33/40), χ²=31.746,P<0.01), mumps (22.5% (9/40) vs.82.5% (33/40), χ²=28.872,P<0.01), rubella (25.0% (10/40) vs.62.5% (25/40), χ²=11.429, P<0.01) before and 6 months after immunization were significantly different. Of the 421 doses of immunization, 25 (5.9%) doses reported controlled systemic or local adverse event. Conclusions: The immunization of pediatric patients with hematological and oncological diseases is of great importance. The newly-developed multidisciplinary cooperation immunization model for Chinese children with hematological and oncological diseases is feasible, and the immunization protocol is safe and has a certain effect.

Abstract
Objective: To assess the anti-hepatitis B surface antibody (HBsAb) titers in children after completion of chemotherapy and (or) hematopoietic stem cell transplantation (HSCT), evaluate the efficacy and safety of the current hepatitis B re-vaccination schedule. Methods: A total of 239 children who completed their chemotherapy and (or) HSCT and visited the vaccination clinic of Shanghai Children's Medical Center from March 2017 to July 2019 were enrolled in this study. According to the previous diseases, patients were divided into leukemia group (85 cases), lymphoma group (30 cases), solid tumor group (49 cases) and non-malignant hematological disease group (75 cases). According to the treatment of previous diseases, the patients were divided into chemotherapy group (126 cases), HSCT group (89 cases) and chemotherapy plus HSCT group (24 cases). HBsAb titers were assessed both at the time of diagnosis and after completion of treatment and some children who were HBsAb seronegative were re-vaccinated with 3 doses of hepatitis B vaccine, the vaccine-related adverse reactions were monitored. HBsAb titers were measured again one month after the completion of inoculation. HBsAb titers were defined as negative at levels <10 U/L and positive at ≥ 10 U/L. Chi-square test or Fisher exact test was used to compare the difference of negative conversion rate of hepatitis B antibody between groups, and Logistic regression was used to explore the risk factors of hepatitis B antibody negative conversion. Results: Among 239 patients, there were 143 males and 96 females. At the time of diagnosis, 179 patients (74.9%) were HBsAb seropositive and 60 patients (25.1%) were HBsAb seronegative. After completion of chemotherapy and (or) HSCT, 133 of 179 children with HBsAb seropositive (74.3%) at diagnosis became HBsAb seronegative. Univariate analysis showed significant differences at the negative conversion rates of HBsAb between different disease groups (χ²=10.211,P=0.015), different treatments groups (χ²=14.899,P<0.01) and different HBsAb titers groups before treatment (χ²=32.117,P<0.01). Logistic regression showed that HSCT (chemotherapy group as the reference, odds ratio (OR)=2.999, 95% confidence interval (CI) 1.276-7.050,P=0.012) and HBsAb titers<328.2 U/L before treatment (HBsAb titers≥328.2 U/L group as the reference, OR=6.397, 95% CI3.159-12.954,P<0.01) were risk factors for negative conversion of HBsAb. Among 48 patients whose HBsAb was seronegative after completion of chemotherapy and (or) HSCT and re-vaccinated with hepatitis B vaccine, 47 (97.9%) cases became HBsAb seropositivie. No serious adverse effects or complications were reported among these patients. Conclusions: After completion of chemotherapy and (or) HSCT, most children completely lose their protective humoral immunity against hepatitis B. Hepatitis B re-vaccination schedule can be efficiently and safely applied in those patients.

Abstract
The nodal-line semimetals have attracted immense interest due to the unique electronic structures such as the linear dispersion and the vanishing density of states as the Fermi energy approaching the nodes. Here, we report temperature-dependent transport and scanning tunneling microscopy (spectroscopy) [STM(S)] measurements on nodal-line semimetal ZrSiSe. Our experimental results and theoretical analyses consistently demonstrate that the temperature induces Lifshitz transitions at 80 and 106 K in ZrSiSe, which results in the transport anomalies at the same temperatures. More strikingly, we observe a V-shaped dip structure around Fermi energy from the STS spectrum at low temperature, which can be attributed to co-effect of the spin-orbit coupling and excitonic instability. Our observations indicate the correlation interaction may play an important role in ZrSiSe, which owns the quasi-two-dimensional electronic structures.

Abstract
Background:The association between IgG4-related disease (IgG4-RD) and malignancies is unclear. No epidemiological data for malignancies in Chinese IgG4-RD patients is available. It is also important to know the risk factors and prognosis for IgG4-RD patients harboring malignancies.Objectives:To investigate the incidence, related factors and prognosis of IgG4-related disease (IgG4-RD) with malignancies in the Chinese cohort.Table 1.Baseline characteristic of IgG4-RD patients with malignancyPatientSexAgeAge at diagnosis of IgG4-RDAge at diagnosis of malignancySerum IgG4(g/L)Organs involvements of IgG4-RD(*Organ with biopsy)Sites of malignancyP1F5958541499Parotid gland*, salivary glandBreast cancerP2M74666810402Pancreas, bile duct, retroperitoneal fibrosis, kidney, prostate, lymph nodesRectal cancerP3M4642402630Lacrimal gland, parotid glandLipoblastomaP4M7068645780Pancreas, bile duct, lung, prostate, lymph nodesThyroid carcinomaP5F62616111600Pancreas, bile duct, salivary gland*, periaortitis, lymph nodes, pituitaryThyroid carcinomaP6M7268683490Pancreas, bile duct, lymph nodesRectal cancerP7M6058582410Pancreas, bile duct, lymph nodesRenal cancerP8M6863683520Pancreas, bile duct, retroperitoneal fibrosis, lung, kidney, artery, lymph nodesRectal cancerP9M36303512400Pancreas, bile ductSkin cancerP10M52495210000Pancreas, parotid gland*, lacrimal gland, lung, prostate, lymph nodesThyroid carcinomaP11F70686917300Parotid gland, lacrimal gland, salivary gland, sinusLung cancerP12M82797958000Pancreas, lacrimal gland*Colon cancerP13F50494514300Uterus*, ovaryOvarian carcinomaP14F52465010000Parotid gland*, lacrimal glandBreast cancerP15F60555712500Pancreas, parotid gland, lacrimal gland, lymph nodes, sinusLymphomaP16M4237407490Lung*, lymph nodesRenal cancerP17M716869415Pancreas*, bile ductProstate cancerTable 2.Related factors for malignancies in patients with IgG4-RDVariablesUnivariate analysisMultivariate analysisUnivariate OR (95%Cl)P-valueMultivariate OR (95%Cl)P-valueHead and Neck involvement0.304 (0.097- 0.952)0.0410.604 (0.152-2.401)0.474Autoimmune pancreatitis5.359 (1.651-17.393)0.0056.230 (1.559-24.907)0.010Eosinophilia0.117 (0.014-0.966)0.0460.094 (0.010-0.883)0.039Figure 1.Standardized incidence ratios of malignancies in patients with IgG4-RD from different studies.Methods:We prospectively analyzed the IgG4-RD patients recruited in Peking Union Medical College Hospital from January 2011 to August 2018 and identified patients diagnosed with IgG4-RD complicating malignancies. Data regarding demographics, clinical features, treatment and prognosis of IgG4-RD patients complicating malignancies were collected and compared to those of age- and sex-matched controls.Results:Among the 587 Chinese patients with IgG4-RD, 17 malignancies were identified. Ten of them developed malignancy after the diagnosis of IgG4-RD, given a standard incidence ratio (SIR) of 2.78 (95%CI 1.33-5.12). Multivariate logistic analysis indicated that autoimmune pancreatitis (OR= 6.230, 95%CI 1.559-24.907, p=0.010) was positively associated with malignancy, whereas eosinophilia (OR= 0.094, 95%CI 0.010-0.883, p=0.039) was negatively related with malignancies. During a median follow-up period of 61.4±26.4 months, all patients with IgG4-RD and malignancies survived.Conclusion:An increased incidence of malignancy was found in Chinese IgG4-RD cohort. Autoimmune pancreatitis is a potential risk factor, whereas eosinophilia is a possible protective factor for complicating malignancies.References:[1] Wallace, Z. S.,et al.

Abstract
Objective: To investigate the relationship between donor chimerism and relapse after allogeneic hematopoietic stem cell transplantation (allo-HSCT) . Methods: The clinical data of 105 patients with acute myeloid leukemia (AML) who underwent allo-HSCT and recurrence-free survival>90 days from January 2010 to January 2019 were retrospectively analyzed. The bone marrow samples were collected at 15, 30, 60, 90, 180, 270, 360 days after transplantation. Donor chimerism was detected by single nucleotide polymorphism (SNP) -PCR. Results: Of the 105 patients, 43 cases were male and 62 cases were female, with a median age of 38 (16-60) years. Till April 2019, the median follow-up was 843 (94-3 261) days. Ninety days after transplantation, 18 cases relapsed, 33 cases died, and 72 cases survived. The 3-year overall survival (OS) rate was (66.8±5.1) %, and the recurrence-free survival (RFS) rate was (65.1±5.0) %. Pre-transplant disease status, pre-transplant minimal residual disease (MRD) , and 90 day post-transplantation chimerism were independent risk factors related to RFS. The risk of recurrence was significantly increased in patients with a donor chimerism rate ≤97.24% at 90 days after transplantation[HR=6.921 (95%CI 2.669-17.950) , P<0.001], which was considered as a sign of early relapse. Conclusion: SNP-PCR is an applicable method for detecting donor chimerism in patients after allo-HSCT. Chimerism rate equal or less than 97.24% at 90 days after transplantation predicts a higher risk of relapse.

Abstract
Objective: To investigate the relations of foramen rotundum structure direction and surrounding structure systematically in order to choose the best approach of percutaneous puncturing of radiofrequency thermocoagulation for treating V2 of primary trigeminal neuralgia. Methods: A total of 122 patients with V2 of primary trigeminal neuralgia for radiofrequency thermocoagulation were enrolled from August 2012 to May 2017 at the First Hospital of Jiaxing. CT scan images were observed retrospectively, to find the inside and outside of the foramen rotundum. The direction of foramen rotundum were recorded and the best approach of puncturing were analyzed. Results: The images were divided into four quadrants with the semi - coronal CT scan plane of the lower margin of the zygomatic arch and the outer edge of foramen rotundum for horizontal axis, and the sagittal plane for the vertical axis. In 122 cases, foramen rotundum direction in outer upper quadrant were 77 cases(63.1%), and in outer under quadrant were 22 cases(18.0%), and in inner upper quadrant were 19 cases(15.6%), and in inner under quadrant were 4 cases(3.3%). Conclusion: The most common foramen rotundum direction is in outer upper quadrant, so the best approach of percutaneous puncturing of radiofrequency thermocoagulation for treating V2 of primary trigeminal neuralgia is the upper side against zygomatic and the inner side against the wall of maxillary sinus.

Abstract
Objective: To explore the ideal procedure of excision and repair for giant desmoid in the abdominal wall and long-termed follow-up results. Methods: Clinical and follow-up data of 24 patients with giant desmoid in the abdominal wall underwent radical removal and immediate abdominal wall reconstruction in Diagnostic and Therapeutic Center of Hernia and Abdominal Wall Diseases, First Affiliated Hospital of People's Liberation Army General Hospital from October 2006 to October 2016 were analyzed retrospectively. Twenty-one female patients with the mean age of 34.6 years and 3 male patients with the mean age of 42.6 years were recruited. The minimal diameter of these tumors was 15 cm, and the maximal diameter was from xiphoid bone to pubic symphysis. Results: All of desmoids were removed radically and proved by the rapid pathologic examination. The size of abdominal wall defect after desmoids removal were 483 (21 cm×23 cm) to 2 100 cm(2) (35 cm×60 cm), averaged 945 cm(2) (27 cm×35 cm). All of defects were repaired with compound synthetic prosthesis using bridging procedure. Twenty-one patients were recovered smoothly and got primary wound healing. Three patients had prosthesis infected during 1 month postoperatively and 1 patient recovered with conservative therapy, the other 2 patients underwent infected prosthesis removal at 2 weeks and 3 months postoperatively, respectively. Twenty-two patients were followed up with the period of 12 to 121 months and the median period was 63 months. No marginal neoplasm recurrence, incisional hernia, and abdominal wall bulge happened. Eight patients developped fresh desmoids in the abdominal cavity or in the back. Two patients died because of intestinal obstruction due to desmoid infiltration, and the other 6 patients still survived along with stable desmoids. Conclusions: Radical removal for patients with giant desmoid in the abdominal wall is an ideal therapeutic method, and compound synthetic patch can be used to repair huge abdominal wall defect, even the defect compromised all of abdominal wall. The long-termed follow-up results showed these procedures had not put bad influence on the quality of patients' life.

Diameters, PSV, EDV, RI, T, SpO(2) and PI of the patients with PH were compared before and after the surgery. The effect of operation was also evaluated. Results: Before surgery, diameters and EDV of the radial and ulnar arteries of the patients with PH were(2.12±0.36) mm, (1.50±0.32) mm, (4.90±1.84) cm/s, (4.71±1.65) cm/s, respectively, after surgery, the diameter of the RA, UA and EDV were (2.45±0.54) mm, (1.87±0.44) mm, (9.37±1.69) cm/s and (9.12±1.54) cm/s, which were significantly increased.Before surgery, RI of the RA and UA of the patients were (0.85±0.05), (0.97±0.07) , respectively, after surgery, RI of the RA and UA were (0.57±0.04), (0.64±0.09), respectively, which were significantly decreased after surgery. The difference was statistically significant (t=-5.23, -2.33, -19.80, -14.68, 3.31, 3.48, all P<0.01). Before surgery, PSV of the RA and UA of the patients were (46.38±15.12) cm/s, (45.60±14.88) cm/s , respectively, after surgery, PSV of the RA and UA were (46.93±16.02) cm/s, (46.19±15.30) cm/s , respectively. The difference was not statistically significant (t=-0.23, -1.39, all P>0.05). Before surgery, T, SpO(2) and PI of the patients were(29.7±1.04) ℃, (93.24±2.23) %, (1.11±0.13) % , respectively, after surgery, T, SpO(2) and PI of the patients were (35.09±1.21) ℃, (98.10±1.34) %, (4.77±1.22)% , respectively. The difference was statistically significant (t=-20.174, -1.140, -23.601, all P<0.05). The symptoms of hyperhidrosis of the patients were disappeared immediately after the surgery in both hands. All of the patients were cured within 3 months and there was no severe complications. Conclusion: Thoracic sympathetic block increase Diameters and EDV but decrease RI of the radial and ulnar arteries of the patients with PH and increase the palms temperature.

Abstract
INTRODUCTION A national survey on critical values in hematology of China laboratories was conducted to determine the current practice and assess the quality indicators so as to obtain a quality improvement. METHODS Laboratories participating were asked to submit the general information, the practice of critical value reporting, and the status of timeliness of critical value reporting. RESULTS A total of 862 laboratories submitted the results. The majority of participants have included white blood cell count, blood platelet count, hemoglobin, prothrombin time, and activated partial thromboplastin time in their critical value lists. Many sources are used for establishing a critical value policy, and some of the laboratories consult with clinicians. The unreported critical value rate, late critical value reporting rate, and clinically unacknowledged rate in China are relatively low, and the median of critical value reporting time is 8-9 minutes. CONCLUSION There exists a wide variety for critical value reporting in hematology in China. Laboratories should establish a policy of critical value reporting suited for their own situations and consult with clinicians to set critical value lists. Critical values are generally reported in a timely manner in China, but some measures should be taken to further improve the timeliness of critical value reporting.

Abstract
Essentials Predicting the occurrence of portosplenomesenteric vein thrombosis (PSMVT) is difficult. We studied 72 patients with acute pancreatitis. Artificial neural networks modeling was more accurate than logistic regression in predicting PSMVT. Additional predictive factors may be incorporated into artificial neural networks. SUMMARY Objective To construct and validate artificial neural networks (ANNs) for predicting the occurrence of portosplenomesenteric venous thrombosis (PSMVT) and compare the predictive ability of the ANNs with that of logistic regression. Methods The ANNs and logistic regression modeling were constructed using simple clinical and laboratory data of 72 acute pancreatitis (AP) patients. The ANNs and logistic modeling were first trained on 48 randomly chosen patients and validated on the remaining 24 patients. The accuracy and the performance characteristics were compared between these two approaches by SPSS17.0 software. Results The training set and validation set did not differ on any of the 11 variables. After training, the back propagation network training error converged to 1 × 10-20 , and it retained excellent pattern recognition ability. When the ANNs model was applied to the validation set, it revealed a sensitivity of 80%, specificity of 85.7%, a positive predictive value of 77.6% and negative predictive value of 90.7%. The accuracy was 83.3%. Differences could be found between ANNs modeling and logistic regression modeling in these parameters (10.0% [95% CI, -14.3 to 34.3%], 14.3% [95% CI, -8.6 to 37.2%], 15.7% [95% CI, -9.9 to 41.3%], 11.8% [95% CI, -8.2 to 31.8%], 22.6% [95% CI, -1.9 to 47.1%], respectively). When ANNs modeling was used to identify PSMVT, the area under receiver operating characteristic curve was 0.849 (95% CI, 0.807-0.901), which demonstrated better overall properties than logistic regression modeling (AUC = 0.716) (95% CI, 0.679-0.761). Conclusions ANNs modeling was a more accurate tool than logistic regression in predicting the occurrence of PSMVT following AP. More clinical factors or biomarkers may be incorporated into ANNs modeling to improve its predictive ability.

Abstract
Functional magnetic resonance imaging (fMRI) has been widely used to identify altered intrinsic local neural activities and global networks of tinnitus patients. In this study, functional connectivity density (FCD) mapping, a newly developed voxelwise data-driven method based on fMRI, was applied for the first time to measure the functional reorganization pattern in thirty-two unilateral pulsatile tinnitus (PT) patients in the early stage of disease (less than 48 months). FCD analysis was employed to compute short-range and long-range FCD values. A correlation analysis with clinical variables was also performed. Compared with normal controls, PT patients showed significantly increased short-range FCD, mainly in the precuneus (PCu), bilateral inferior frontal gyrus (IFG) and middle occipital gyrus (MOG), and increased long-range FCD in the PCu, posterior cingulate cortex (PCC), and bilateral middle frontal gyrus (MFG). In addition, correlation analysis showed positive correlations between PT duration and short-range FCD values in the right MOG. Positive correlations were also found between the disease duration and the long-range FCD value in the PCC. The increased short-/long-range FCD in bilateral dorsal visual areas indicated that the enhanced pathway between the auditory cortex and bilateral dorsal visual areas may have activated the "auditory occipital activations" (AOAs) pathway. The bilaterally altered FCD values in the dorsal visual areas reflected the cooperation of different brain areas. This study is a foundation of the connectivity research in PT patients. Our work may advance the understanding of the disrupted neural network of patients with PT.

Abstract
OBJECTIVE To systematically evaluate the effectiveness of devascularization and shunt on patients with portal hypertension. METHODS Relevant studies compared devascularization and shunt for the treatment of portal hypertension were identified searching the PubMed, Embase, Elsevier, CNKI (China National Knowledge Infrastructure) database and Cochrane Trial Register searches until December 2013. Data of interest for devascularization and shunt including postoperative recurrent bleeding, postoperative hepatic encephalopathy,ascites, operative mortality rate, and long term survival rate were subjected to meta-analysis. RESULTS Eleven studies were included in the study, the results of the meta-analysis showed that all eleven clinical studies demonstrated a significantly higher postoperative recurrent bleeding rate with devascularization group than with shunt group (Odds Ratio =2.14, 95% CI =(1.42, 3.21), P = 0.0003),the rate of hepatic encephalopathy in the devascularization group was significantly lower compared with the shunt group (Odds Ratio =0.56, 95% CI =(0.38, 0.82), P = 0.003); Our meta-analysis of three clinical studies revealed that the reduction of ascites in the devascularization group was significantly less than the shunt groups (Odds Ratio =0.48, 95% CI =(0.26, 0.89), P = 0.02), the operative mortality rate was not significantly different between the devascularization group than for shunt group (Odds Ratio =1.54, 95% CI = (0.91,2.63), P = 0.11). And the long-term survival rate was not significantly different between the devascularization and shunt groups (Odds=1.13, ratio, 95% CI =(0.64, 1.99), P = 0.68). CONCLUSIONS Devascularization and shunt have different advantages and disadvantages respectively which reflected in postoperative complications and long term survival rate.

Abstract
BACKGROUND Neurofibromatosis with gastrointestinal stromal tumours have been reported several times, while neurofibromatosis with retroperitoneal stromal tumours are very rare. CASE DESCRIPTION We report the case of a 44-year-old man with a long history of neurofibromatosis. He complained of severe constipation and left leg pain. The patient's examination showed prominent peripheral cutaneous neurofibromas mainly in the belly and limbs, especially a huge mass in his abdomen, no less than ten café-au-lait spots, four Lisch nodules of the iris. Computed tomography and magnetic resonance imaging revealed a round and lobular mass in the retroperitoneal space. It was a well-circumscribed, hypervascular mass with cystic necrosis. A surgical resection was performed, and pathology and immunohistochemistry findings were consistent with stromal tumour. The c-kit gene and platelet-derived growth factor receptor-α gene mutations are not observed in the specimen. CONCLUSIONS Neurofibromatosis with retroperitoneal stromal tumour is very rare, and radiological, pathological and immunohistochemical examination may identify it. Surgical resection may be the unique method of cure for it.

Abstract
ABSTRACTLinearized augmented plane wave (LAPW) results are presented for FeO at high pressures using the Generalized Gradient Approximation (GGA) to study the high-spin low-spin transition previously predicted by LAPW with the Local Density Approximation (LDA) and Linear Muffin Tin Orbital (LMTO-ASA) methods within the GGA. We find a first-order transition at a pressure of about 105 GPa for the cubic lattice, consistent with earlier LAPW results, but much lower than obtained with the LMTO. The results are generally consistent with recent Mössbauer experiments that show a transition at about 100 GPa. We also discuss the origin of the transition, and show that it is not due to electrostatic crystal-field effects, but is rather due to hybridization and band widening with pressure. Examination of experimental data and computations suggest that the high pressure hexagonal phase of FeO is likely a polytype between the B8 NiAs and anti-B8 AsNi structures. The former is predicted to be an antiferromagnetic metal, and the latter an antiferromagnetic insulator. Implications for geophysics are discussed.

Abstract
In situ x-ray diffraction measurements revealed that FeS, a possible core material for the terrestrial planets, transforms to a hexagonal NiAs superstructure with axial ratio (c/a) close to the ideal close-packing value of 1.63 at high pressure and high temperature. The high-pressure-temperature phase has shorter Fe-Fe distances than the low-pressure phase. Significant shortening of the Fe-Fe distance would lead to metallization of FeS, resulting in fundamental changes in physical properties of FeS at high pressure and temperature. Calculations using the density of the high-pressure-temperature FeS phase indicate that the martian core-mantle boundary occurs within the silicate perovskite stability field.

Abstract
The significance of endothelial P120 catenin (P120ctn) activity has been recognized for many years, however it was only recently that the complicated regulation of this constitutively expressed enzyme in endothelial cells was identified. A critical component of the P120ctn regulatory cycle in endothelial cells is its intracellular localization to caveolae. The caveolar coordination of P120ctn, more specifically its interaction with E-cadherin plays a major role in normal endothelial P120ctn activity and vascular bioavailability of nitric oxide. We have recently shown that the presence of P120ctn exon 7 Phe389Leu polymorphism caused diminished shear which was dependent catenin activation, was less extensively associated with caveolae, and had a decreased degree of interaction with E-cadherin. Here, we carried out preliminary investigations to identify possible mechanisms of the genotype-dependent endothelial cell responses we observed in our previous investigations. Through this approach we tested the hypothesis that computer simulations could provide insights regarding the contribution of this single nucleotide polymorphism to regulation of the P120ctn isoform. We observed that in the Phe/Leu and Leu/Leu mutant genotypes, the amount of P120ctn associated with E-cadherin was significantly lower. Additionally, we have shown, using a theoretical computational model, that mutation of an amino acid at position 389 might affect the protein-protein interactions and localization of the P120ctn protein. These alterations might also affect the protein function and explain the enhanced disease risk associated with the presence of Phe389Leu polymorphism in the P120ctn protein.

Abstract
BACKGROUND Depression has been associated with a decrease in intracellular serotonin (5-HT) reuptake through its transporter, SERT. The 5-HT transporter long promoter region (5-HTTLPR) deletion in the SERT gene has also been associated with a decrease in 5-HT reuptake. Conversely, increases in extracellular 5-HT have been associated with increased temperature. It has not been established, however, whether body temperature in depressed patients is different from controls. Here, we hypothesized that temperature would be increased in depressed patients as well as in those with the 5-HTTLPR deletion. METHODS A strict oral temperature protocol employed single, cross-sectional, naturalistic time-of-day temperature measures in 125 subjects (46 normal controls, 79 outpatients with major depression). Controls and depressed patients were free of psychotropic medication and classified by the Structured Clinical Interview for Psychiatric Diagnoses. Eighty-one of the subjects (68 depressed, 13 normal) were additionally genotyped for 5-HTTLPR polymorphisms. RESULTS Depressed patients had a significantly higher uncorrected body temperature (mean +/- SD 98.38 +/- 0.61 degrees F) than controls (mean +/- SD 98.13 +/- 0.59 degrees F; F = 4.8, p = 0.03). An age (F = 14.09, p < 0.001) and time-of-day (11.4, p = 0.001) correction revealed a more robust (F = 14.02, p < 0.001) difference between depressed patients (mean +/- SD 98.44 +/- 0.55 degrees F) and controls (mean +/- SD 98.02 +/- 0.56 degrees F). When normalized for age and circadian differences between subjects, random, outpatient oral temperatures had a sensitivity of 63% and a specificity of 76% in identifying the depressed subjects from the controls. Independent of depression, subjects with the 5-HTTLPR deletion (short SERT allele) were warmer (mean +/- SD 98.33 +/- 0.65 degrees F) than those lacking the short allele on either chromosome (mean +/- SD 97.91 +/- 0.69 degrees F; F = 7.0, p = 0.01). However, the genotype did not explain the temperature differences between controls and depressed patients. CONCLUSION This is the first demonstration of an increased daytime body temperature in cases with major depression. Subjects with a corrected temperature above 98.3 degrees F were 2.6-fold more likely to be depressed. The results may strengthen the hypothesis of an inflammatory component of depression. In addition, the findings suggest a potential link between genetic differences in 5-HT transport and body temperature.

Abstract
Multiple kinase pathways determine serotonin transporter (SERT) regulation. We hypothesized a decrease in kinase expression with chronic selective serotonin reuptake inhibitor (SSRI) administration necessary to regulate extracellular serotonin. We studied whole brain kinase mRNA expression on Affymetrix gene chips in rats treated with placebo 3 and 21 days, fluoxetine 3 and 21 days, and citalopram 21 days. Protein kinase C (PKC)-delta, PKC-gamma, stress-activated protein kinase, cAMP-dependent protein kinase beta isoform, Janus protein kinase, and phosphofructokinase M were all down regulated chronically with citalopram and fluoxetine, but not with acute fluoxetine. The results are consistent with homeostasis of SERT function through a decrease in PK expression.
