Abstract
Objective: To observe the recurrence condition of hepatitis B in different risk groups after liver transplantation in an attempt to provide useful information on whether to discontinue hepatitis B immunoglobulin (HBIG) in the future at an early stage. Methods: The patient population was divided into high, low-risk, and special groups [especially primary hepatocellular carcinoma (HCC)] according to the guidelines for the prevention and treatment of hepatitis B recurrence after liver transplantation. The recurrence condition and risk factors in this population were observed for hepatitis B. Measurement data were analyzed using a t-test and a rank-sum test. Count data were compared using a χ(2) test between groups. Results: This study finally included 532 hepatitis B-related liver transplant cases. A total of 35 cases had HBV recurrence after liver transplantation, including 34 cases that were HBsAg positive, one case that was HBsAg negative, and 10 cases that were hepatitis B virus (HBV) DNA positive. The overall HBV recurrence rate was 6.6%. The recurrence rate of HBV was 9.2% and 4.8% in the high- and low-risk HBV DNA positive and negative groups before surgery (P = 0.057). Among the 293 cases diagnosed with HCC before liver transplantation, 30 had hepatitis B recurrence after surgery, with a recurrence rate of 10.2%. The independent related factors for the recurrence of hepatitis B in patients with HCC after liver transplantation were HCC recurrence (HR =181.92, 95%CI 15.99~2 069.96, P < 0.001), a high postoperative dose of mycophenolate mofetil dispersible tablets (MMF) ( HR =5.190, 95%CI 1.289~20.889, P = 0.020), and a high dosage of HBIG (HR = 1.012, 95%CI 1.001~1.023, P = 0.035). Among the 239 cases who were non-HCC before liver transplantation, five cases (recurrence rate of 2.1%) arouse postoperative hepatitis B recurrence. Lamivudine was used in all cases, combined with on-demand HBIG prophylaxis after surgery. There was no hepatitis B recurrence in non-HCC patients who treated with entecavir combined with HBIG after surgery. Conclusion: High-barrier-to-resistance nucleotide analogues combined with long-term HBIG have a good effect on preventing the recurrence of hepatitis B after liver transplantation. The discontinuation of HBIG may be considered at an early stage after administration of a high-barrier-to-resistance nucleotide analogue in low-risk patients. Domestically, the HBV infection rate is high, so further research is still required to explore the timing of HBIG discontinuation for high-risk patients, especially those with HCC.

Abstract
Objective: The present retrospective study aimed to analyses the ventilation efficacy and safety of new nasopharyngeal airway applied in left atrial appendage occlusion. Methods: A total of 37 advanced aged patients diagnosed with atrial fibrillation(>65 years)who underwent left atrial appendage occlusion (LAAO) in Xuanwu Hospital of Capital Medical University from March 2021 to March 2022 were enrolled in this study. All patients received supplemental oxygen by a new nasopharyngeal airway to ensure intraoperative ventilation. The primary outcome was the occurrence of hypoxemia. The secondary outcomes included the incidence of hypotension after anesthesia, the incidence of body movement during surgery, significant fluctuations of the vital signs such as mean arterial pressure (MAP), heart rate (HR), saturation of pulse oxygen (SpO2) and respiratory rate (RR) at different time points (T1: pre-operation; T2: at the time of placing nasopharyngeal airway; T3: at the time of placing transesophageal echocardiography(TEE); T4: at the time of TEE intraoperative exploration; T5: end of the surgery; T6: at the time of patient woke up), and the incidence of postoperative adverse events. Results: There were 24 males and 13 females with a mean age of (73.8±7.7) years. The incidence of hypoxemia was 16.2% (6/37), which could return to normal after simple treatment. The incidence of hypotension was 27.0% (10/37), occurred after anesthesia induction mainly.32.4% (12/37) of the patients experienced movements, but no adverse events led to surgical termination. MAP at different time points was significantly different (P=0.001), but other vital signs of HR, SpO2 and RR were not significantly different(all P>0.05), without serious hemodynamic fluctuations. The incidence of postoperative adverse cardiovascular events was 10.8% (4/37), and delirium was 2.7% (1/37). All patients successfully completed the surgery and were safely discharged from the hospital. Conclusion: The new nasopharyngeal airway can meet the requirements of airway management during left atrial appendage occlusion under intravenous anesthesia without serious adverse events.

Abstract
Objective: To investigate the clinicopathological features, diagnosis and differential diagnosis of adrenal cortical carcinoma (ACC) in children. Methods: Twenty-five children with ACC diagnosed in the Department of Pathology, Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine, Shanghai, China from March 2014 to August 2022 were retrospectively analyzed. The related literature was reviewed. Results: A total of 25 children with ACC were collected, including 11 males and 14 females, with a male to female ratio of 1.0∶1.3. The patient ages ranged from 8 months to 14 years (median, 4 years). Eighteen cases with clinical data had functional tumors (18/22, 81.8%) presenting with virilization or precocious puberty (15/18), symptoms related to hypercortisolism (8/18) or endocrine symptoms mixed with both (5/18), while 3 cases (3/22, 13.6%) had unknown clinical data. The clinical manifestations of four patients with nonfunctional tumors were an abdominal mass and/or abdominal pain, walking instability and others. Grossly, the average maximum diameter of the tumor was 9.4 cm. Most of the tumors were nodular and partially encapsuled. The cut surfaces were gray or gray brown, soft with hemorrhage. Histologically, the tumor cells were diffusely distributed, separated by a vascular-rich network. The tumor cells were large, with distinct nucleoli, abundant eosinophilic or clear cytoplasm, and round or oval nuclei. The mitotic index was high, and atypical mitoses were common. Necrosis, calcification, capsule invasion or/and venous invasion were present. In some cases, the tumor invaded the surrounding soft tissues or kidneys. Immunohistochemically, the tumor cells were diffusely positive for syn and SF1 and focally positive for α-inhibin, Melan A and Calretinin, but negative for CgA. Ki-67 proliferation index ranged from 2%-90%. TP53 gene status was examined in 7 cases, in which mutations were detected in 4 cases. Follow-up data was obtained in 21 patients, among whom 18 received chemotherapy and 3 received radiotherapy. Distant metastasis occurred in 13 patients. Median progression-free survival (PFS) was 11.2 months and median overall survival (OS) was 54.7 months. Patients aged less than 5 years had a better prognosis for OS (P<0.05) than the older ones (≥5 years), but a similar PFS (P>0.05). Male patients and Ki-67 proliferation index <15% had a better prognosis tendency for OS, but there was no statistically significant difference (P>0.05). Conclusions: ACC in children is a rare, often functional tumor associated with Li-Fraumeni genetic syndrome and has a poor prognosis. Diagnosis and differential diagnosis require a combination of morphological, phenotypic and clinical analysis.

Abstract
Carcinoma of unknown primary (CUP) is a kind of metastatic tumor whose primary origin cannot be identified after adequate examination and evaluation. The main treatment modality of CUP is empiric chemotherapy, and the median overall survival time is less than 1 year. Compared with immunohistochemistry, novel method based on gene expression profiling have improved the sensitivity and specificity of CUP detection, but its guiding value for treatment is still controversial. The approval of immune checkpoint inhibitors and pan-cancer antitumor agents has improved the prognosis of patients with CUP, and targeted therapy and immunotherapy based on specific molecular characteristics are the main directions of future research. Given the high heterogeneity and unique clinicopathological characteristics of CUP, "basket trial" is more suitable for clinical trial design in CUP.

Abstract
Objective: To construct and analyze the functional network changes of hemi-brain in patients with brain tumor before and after anesthesia by using resting state functional magnetic resonance imaging (rs-fMRI). Methods: A total of 18 right-handed patients were prospectively included (6 males and 12 females). The patients underwent glioma resection in Peking University International Hospital from December 2018 to December 2021, and age ranged from 20 to 65 (45.1±13.6) years, with American Society of Anesthesiologists (ASA) grade of Ⅰ-Ⅱ. MRI scans were performed while the patient was awake and at the depth of surgical anesthesia. The functional network of healthy lateral brain was constructed and analyzed by means of graph theory, and its global and local topological properties were calculated. Global topology attributes included global efficiency (Eg), local efficiency (Eloc), clustering parameters (Cp), length parameter of shortest path (Lp), and small world (SW). Topology attributes of nodes included node degree (ND), node efficiency (NE) and between centrality (BC). The global and nodal topological properties of the hemi-brain network were compared between patients with different hemispherical space occupying under wakefulness and anesthesia. Results: At the awake state, Eloc and Cp in the global topological attributes of hemi-brain network were 0.259±0.007 and 0.197±0.010, respectively, and decreased to 0.242±0.013 and 0.177±0.021, respectively after anesthesia, with statistically significant differences (all P<0.01). The topological attributes of the nodes in hemi-side brain showed that ND, NE and BC were increased in the default mode network-related brain regions, while NE and BC were decreased in the limbic system and subcortical structures. Eloc and Cp were 0.258±0.008 and 0.198±0.008 respectively in the patients with left hemisphere space occupying, and decreased to 0.241±0.011 and 0.177±0.015 respectively after anesthesia, with statistically significant differences (all P<0.01). However, only Eloc decreased in patients with right hemisphere space occupying after anesthesia, and Eloc was 0.260±0.006 and 0.243±0.016 respectively when awake and after anesthesia, with statistically significant differences (P<0.05). The topological attributes of nodes in patients with space occupying in different cerebral hemispheres showed bidirectional changes after anesthesia, and patients with space occupying in the left cerebral hemisphere were more likely to be widely affected after anesthesia. The effects of anesthetic drugs may show hemispheric laterality. If the tumor was in the dominant hemisphere, the compensatory function of the dominant side was more likely to be damaged. Conclusions: During anesthesia-induced loss of consciousness in patients with brain tumors, both the ability to integrate information and the functional connections between local regions are weakened, and some brain regions have functional connection reorganization. The changes of brain network after anesthesia are bidirectional regulation.

Abstract
Objective: To investigate the changes of brain network characteristics in patients with depression before and after precise repetitive transcranial magnetic stimulation (rTMS) treatment. Methods: Patients with depression in the Second Affiliated Hospital of Xinxiang Medical University and healthy volunteers in the community of Xinxiang city from February 2018 to March 2019 were simultaneously recruited. The left dorsolateral prefrontal cortex was precisely selected as the stimulation target through the latest Human Brainnetome Atlas, and the near infrared navigation was used to achieve accurate brain stimulation treatment in combination with the structural magnetic resonance data. Moreover, functional connectivity was analyzed before and after rTMS treatment in significantly altered brain areas of patients with depression. Results: Nineteen patients (11 males and 8 females) with depression were included, aged (34±11) years. Meanwhile, 22 healthy controls (9 males and 13 females), aged (30±9) years, were also enrolled. Functional connectivity of insular cortex was decreased in depression patients when the insula was analyzed as the target area (P<0.05). The functional connection from insula to middle frontal lobe and superior parietal lobe in patients with depression decreased before rTMS treatment (P<0.05), but increased after rTMS treatment (P<0.05). The functional connection between dIg_L of the insula and the right middle prefrontal lobe was correlated with Beck Anxiety Index (BAI) before rTMS treatment and Beck Depression Index (BDI) after rTMS treatment (r=0.737, P=0.003; r=0.696, P=0.005). Conclusions: Abnormal functional connectivity of insula may be the brain imaging mechanism of rTMS treatment. Precise brain region selection based on Human Brainnetome Atlas provides a new technical method for clinical rTMS precision treatment.

Abstract
Objective: To characterize the histopathological subtypes and their clinicopathological parameters of gender and onset age by common, rare and sparse primary esophageal malignant tumors (PEMT). Methods: A total of 272 437 patients with PEMT were enrolled in this study, and all of the patients were received radical surgery. The clinicopathological information of the patients was obtained from the database established by the State Key Laboratory of Esophageal Cancer Prevention & Treatment from September 1973 to December 2020, which included the clinical treatment, pathological diagnosis and follow-up information of esophagus and gastric cardia cancers. All patients were diagnosed and classified by the criteria of esophageal tumor histopathological diagnosis and classification (2019) of the World Health Organization (WHO). The esophageal tumors, which were not included in the WHO classification, were analyzed separately according to the postoperative pathological diagnosis. The χ2 test was performed by the SPSS 25.0 software on count data, and the test standard α=0.05. Results: A total of 32 histopathological types were identified in the enrolled PEMT patients, of which 10 subtypes were not included in the WHO classification. According to the frequency, PEMT were divided into common (esophageal squamous cell carcinoma, ESCC, accounting for 97.1%), rare (esophageal adenocarcinoma, EAC, accounting for 2.3%) and sparse (mainly esophageal small cell carcinoma, malignant melanoma, etc., accounting for 0.6%). All the common, rare, and sparse types occurred predominantly in male patients, and the gender difference of rare type was most significant (EAC, male∶ female, 2.67∶1), followed with common type (ESCC, male∶ female, 1.78∶1) and sparse type (male∶ female, 1.71∶1). The common type (ESCC) mainly occurred in the middle thoracic segment (65.2%), while the rare type (EAC) mainly occurred in the lower thoracic segment (56.8%). Among the sparse type, malignant melanoma and malignant fibrous histiocytoma were both predominantly located in the lower thoracic segment (51.7%, 66.7%), and the others were mainly in the middle thoracic segment. Conclusion: ESCC is the most common type among the 32 histopathological types of PEMT, followed by EAC as the rare type, and esophageal small cell carcinoma and malignant melanoma as the major sparse type, and all of which are mainly occur in male patients. The common type of ESCC mainly occur in the middle thoracic segment, while the rare type of EAC mainly in the lower thoracic segment. The mainly sparse type of malignant melanoma and malignant fibrous histiocytoma predominately occur in the lower thoracic segment, and the remaining sparse types mainly occur in the middle thoracic segment.

Abstract
Objective: To study the clinicopathologic characteristics and risk factors of sarcoma arising in fibrous dysplasia. Methods: A total of 18 cases were collected from January 2008 to July 2018 in Shanghai Jiaotong University Affiliated Sixth People's Hospital. The characteristics and the histologic type were retrospectively reviewed. IBM SPSS 19 was used for statistical analysis. Results: The male to female ratio of patients with fibrodysplastic sarcomatosis was 1.57∶1.00. The age of onset ranged from 24 to 87 years (mean 49 years). The long bones, especially the femur, were most frequently involved. Nine cases were osteosarcomas, three cases were high grade sarcoma and six cases were low grade sarcoma. Logistic regression analysis showed that age was an independent risk factor for sarcomatous change, compared with polyostotic or recurrent cases. Value of Wals was 13.61 (P<0.05), and odds ratio was 12.82,95% confidence interval was 3.31-49.70. Conclusions: Fibrodysplasia sarcomatosis is clinically nonspecific and the risk of sarcomatous changes increases approximately 12-fold when age of onset of fibrous dysplasia is over 40 years.

Abstract
Objective: To explore the high risk factors of catheter-related thrombosis (CRT) in breast cancer patients, and provide the basis for the development of appropriate prevention and treatment strategies. Methods: A total of 1 432 breast cancer patients scheduled to receive central venous catheterization in National Cancer Center/National Clinical Research Center for Cancer/Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College from January 1, 2015 to August 31, 2019 were selected. Baseline information and catheterization information of patients were collected. The occurrence of CRT was confirmed by vascular ultrasound examination, and the influencing factors of CRT were analyzed. Results: The total number of catheter days were 121, 980 days in 1 432 patients with breast cancer, and the average number of catheter days in each patient was 85.2 days. The incidence of CRT was 6.8% (97/1 432), which was 0.79 cases/1 000 catheter days. Among 815 patients with centrally inserted central venous catheters (CICC), 43 (5.3%) had CRT, which was 0.70 cases/1 000 catheter days. Among 617 patients with peripherally inserted central venous catheters (PICC), 54 (8.8%) developed CRT, which was 0.90 cases/1 000 catheter days. CRT was most common in subclavian vein (63.9%). Multivariate regression analysis showed that age ≥ 60 years old (OR=1.712, 95% CI: 1.056-2.775, P=0.029), PICC (OR=1.732, 95% CI: 1.130-2.656, P=0.012), the catheter position except subclavian vein (OR=10.420, 95% CI: 1.207-89.991), secondary adjustment of catheter position (OR=3.985, 95% CI: 1.510-10.521, P=0.005) and high D-Dimer level (OR=1.129, 95% CI: 1.026-1.241, P=0.012)were independent risk factors for CRT. Conclusions: The CRT problem can't be ignored in the clinical treatment of breast cancer patients with central venous catheterization. Screening the appropriate age of patients and the type of central venous catheters, reducing the secondary adjustment of catheter position, and timely monitoring the level of D-dimer are helpful to the prevention and treatment of CRT.

Abstract
Objective: To analyze the characteristics of high-grade squamous intraepithelial lesion (HSIL) diagnosed by cervical tissue sampling in postmenopausal women. Methods: A retrospective study was performed on 2 013 patients with HSIL diagnosed by cervical tissue sampling under colposcopy and treated by cervical conization at the First Affiliated Hospital of Zhengzhou University from June 2017 to November 2018, to compare the difference of patients' clinical features, HPV test, liquid-based thin-layer cytology (TCT), performance of colposcopy and biopsy pathology, pathology after cervical conization between 439 postmenopausal patients and 1 574 pre-menopausal patients. Results: (1) Clinical features: the proportion of contact bleeding showed no significant difference between postmenopausal patients and pre-menopausal patients [4.3% (19/439) vs 6.4% (101/1 574); χ²=2.672, P=0.102]. Among the patients with contact bleeding, the proportion of cervical cancer after cervical cone resection was significantly higher in postmenopausal patients compared with pre-menopausal patients [10/19 vs 22.8% (23/101); χ²=7.157, P=0.007]. Among the patients found by routine screening, the proportion of cervical cancer after cervical cone resection was significantly higher in postmenopausal patients compared with pre-menopausal patients [9.0% (38/420) vs 4.3% (63/1 473); χ²=14.726, P<0.01]. The proportion of smooth cervix was higher in postmenopausal patients compared with pre-menopausal patients [63.6% (279/439) vs 35.5% (558/1 574); χ²=111.601, P<0.01]. (2) High-risk HPV infection: there was no significant difference in the high-risk HPV positive rate between the postmenopausal group and the pre-menopausal group [92.0% (404/439) vs 94.4% (1 486/1 574); χ²=3.394, P=0.065]; the HPV 16 infection was the most common type, but there was no significant difference in the HPV 16 infection rate between the two groups [65.8% (289/439) vs 68.0% (1 070/1 574); χ²=0.722, P=0.395]. (3) TCT test: TCT test results included negative for intraepithelial lesion and malignancy (NILM), atypical squamous cell of undetermined signification (ASCUS), atypical squamous cells cannot exclude high-grade lesion (ASC-H), low grade squamous intraepithelial lesion (LSIL), HSIL, compared with the different results of TCT examination, there were not statistically significant difference between postmenopausal and pre-menopausal patients (all P>0.05). (4) The performance of colposcopy: the proportion of insufficient colposcopy and the proportion of cervical type Ⅲ conversion area were higher in postmenopausal patients compared with pre-menopausal patients [87.5% (384/439) vs 32.5% (511/1 574), P<0.01; 80.0% (351/439) vs 21.9% (344/1 574), P<0.01]. The proportion and positive rate of endocervical curettage (ECC) in postmenopausal patients were higher than those in pre-menopausal patients [35.3% (155/439) vs 20.4% (322/1 574), P<0.01; 67.7% (105/155) vs 53.1% (171/322), P=0.003]. The proportion of lesions involving the vaginal wall was higher in postmenopausal patients compared with pre-menopausal patients [5.9% (26/439) vs 1.0% (16/1 574); χ²=40.443, P<0.01]. There was a positive correlation between vaginal wall lesions and cervical lesions in postmenopausal patients (r=0.660, P<0.01). (5) Postoperative pathology: the positive rate of margin and the proportion of pathological escalation after cervical conization were significantly higher in postmenopausal patients compared with pre-menopausal patients [14.6% (64/439) vs 4.8% (75/1 574), 10.9% (48/439) vs 5.5% (86/1 574); P<0.01]. Conclusions: Colposcopy in postmenopausal women is often inadequate, and the cervix is mostly type Ⅲ transformation zone. The lesion in postmenopausal women is more likely to involve the cervical canal and vaginal wall. Clinical attention should be paid to cervical tube curettage and comprehensive examination of the vaginal wall. The high rate of positive margins and a high proportion of pathological upgrading after cervical conization in postmenopausal patients requires further active intervention.

Abstract
A high-temperature oven based on the inductive heating technology was developed successfully at the Institute of Modern Physics in 2019. This oven features a durable operation temperature of over 2000 °C inside the tantalum susceptor. By carefully designing the oven structure, the material compatibility issue at high temperature has been successfully solved, which enables the production and routine operation of refractory metal ions with SECRAL-II (Superconducting Electron Cyclotron Resonance ion source with Advanced design in Lanzhou No. 2). To further apply this type of oven to the room temperature ECR ion sources LECR4 and LECR5 (Lanzhou Electron Cyclotron Resonance ion source No. 4 and 5), a mini-inductive heating oven has been fabricated and tested in 2020. By directly evaporating calcium oxide, some high charge state calcium beams have been produced successfully, such as 52 euA of 40Ca16+, 30 euA of 40Ca17+, and 12 euA of 40Ca18+. The detailed design and testing results will be presented and discussed.

Abstract
Ado-trastuzumab emtansine (T-DM1) is an antibody-drug conjugate (ADC) composed of trastuzumab, a linker, and a microtubule inhibitor. T-DM1 combines the highly effective targeting of antibody with the high anti-tumor activity of cytotoxic drugs, while reduces the off-target toxic side effects of cytotoxic drugs. T-DM1 has been applied in neoadjuvant therapy of HER2-positive breast cancer and rescue treatment of advanced breast cancer, greatly improves the prognosis of breast cancer patients. More and more clinical trials of T-DM1 for HER2 breast cancer and other solid tumors are ongoing, and more positive results are expected.

Abstract
Macrophages have been reported to participate in inflammation, tissue homeostasis and tissue repair. The detailed mechanism of macrophage-mediated tissue repair is not clear. CXCL-10, secreted by monocytes, endothelial cells and fibroblasts, mediates immune response and angiogenesis by binding to CXCR3. In this study, the expression of CXCL-10 and CXCR3 in porcine lung injury induced by porcine reproductive and respiratory syndrome virus (PRRSV) infection was firstly examined. The results showed that the expression of both CXCL-10 and CXCR3 increased in the infected pig lungs. In addition, the increased expression of CXCL-10 and CXCR3 in macrophage treated by poly (I:C) was also observed, suggesting the autocrine system existed in macrophages. Furthermore, CXCL-10 treatment induced upregulation of Arg1 and VEGFa, and downregulation of TNFα in macrophage, and CXCR3 antagonist AMG487 treatment presented the contrary effects on the expression of Arg1, VEGFa, and TNFα. CXCL- 10-stimulated effects were dependent on PI3K/Akt signaling pathway. Wound-healing assay showed that CXCL-10 treatment macrophage conditioned medium promoted the healing process of endothelial cells. Our results suggested that CXCL-10/CXCR3 in macrophage may mediate tissue repair by regulating the macrophage expression of Arg1, VEGFa and TNFα. Modulation of CXCL-10/CXCR3 axis in macrophage may be a potential therapeutic strategy for tissue injury and repair.

Abstract
Objective To investigate the clinical efficacy and outcomes of the coracoid osteotomy with or without Bristow–Latarjet procedures in the treatment of chronic anterior shoulder dislocation (CASD). Methods Between January 2013 and January 2019, 20 shoulders of 18 patients who were diagnosed with chronic anterior dislocation and underwent open reduction in our trauma center were retrospectively studied. Open coracoid osteotomy with Bristow–Latarjet procedures were performed on 16 shoulders and open coracoid osteotomy without Bristow–Latarjet procedures were performed on four shoulders. Open coracoid osteotomy with or without Bristow–Latarjet procedures were chosen on the basis of the stability of the shoulder after reduction. Outcomes were assessed preoperatively and postoperatively with the visual analog scale (VAS) for pain, the American Shoulder and Elbow Surgeons (ASES) score, the University of California Los Angeles (UCLA) shoulder rating scale, and the range of motion (ROM) for shoulder activity. Results There were three males and 15 females with an average age of 60.94 ± 2.69 years. The time between dislocation and treatment ranged from 21 to 240 days with an average of 73.3 ± 14.4 days. All patients were available for a mean follow‐up of 15.2 ± 4.3 months. No procedure‐related death or incision‐related superficial or deep tissue infection was identified in all cases. No iatrogenic neurovascular injuries or fractures were found in this study. At the time of 12 months follow‐up, the range of motion and the shoulder functional evaluation (VAS [P < 0.001], ASES [P < 0.001], and UCLA score [P < 0.001]) in patients who underwent Bristow–Latarjet procedures were significantly improved. Subluxation after surgical procedure was found and confirmed in one patient and this patient refused to undergo revision surgery. According to the Samilson and Prieto classification system, 16 shoulders were assessed as grade 0, three shoulders were grade 1, one shoulder was grade 2. Conclusions Coracoid osteotomy with or without Bristow–Latarjet procedure yielded an acceptable clinical result in this study. This method has the advantages of enlarging the exposure of surgical field, assisting reduction of shoulder, and convenient conversion to Bristow–Latarjet procedure. It is an efficient and reliable method for treatment of chronic anterior shoulder dislocation. A 69‐year‐old woman diagnosed with right chronic anterior shoulder dislocation with large Hill–Sachs lesion. The latarjet procedure with remplissage technique was applied for this patient.

Abstract
MiR-23a-5p is involved in the occurrence and development of some serious diseases, but its effects on intestinal ischemia-reperfusion (II/R) injury is unclear. In this research, the hypoxia/reoxygenation (H/R) model on IEC-6 cells and II/R model in mice were used. The data showed that the ROS level in model group was significantly increased compared with control group. The level of intestinal MPO was increased and serum SOD was decreased in mice compared with sham group. Moreover, the expression levels of miR-23a-5p in model groups were obviously increased in vitro and in vivo, while the expression levels of PPARα, FOXO3α, PGC-1α, Nrf2, CAT, NQO1, HO-1 and SOD2 were significantly decreased. The double luciferase reporter gene assay showed that there was binding site between miR-23a-5p and PPARα. When miR-23a-5p was inhibited or PPARα gene was overexpressed, H/R-caused cell damage was alleviated and ROS level was decreased compared with NC group. PPARα expression level was increased, accompanied by the increased levels of FOXO3α, PGC-1α, Nrf2, CAT, NQO1, HO-1 and SOD2. After enhancing miR-23a-5p expression or silencing PPARα gene, H/R-caused cell damage was further aggravated compared with NC group, and ROS level was increased associated with the decreased levels of FOXO3α, PGC-1α, Nrf2, CAT, NQO1, HO-1 and SOD2. Our study demonstrated that miR-23a-5p exacerbated II/R injury by promoting oxidative stress via targeting PPARα, which should be considered as one new drug target to treat II/R injury.

Abstract
In order to diagnose the electron cyclotron resonance (ECR) plasma, a high-efficiency collimation system has been developed at the Institute of Modern Physics, and the bremsstrahlung spectra in the range of 10 keV-300 keV were measured on a third generation superconducting ECR ion source, SECRAL-II, with a CdTe detector. Used as a comparative index of the mean energy of the high energy electron population, the spectral temperature, Ts, is derived through a linear fitting of the spectra in a semi-logarithmic representation. The influences of some main source parameters, such as the neutral gas pressure, extraction voltage, microwave power, and bias disk voltage, on the high energy electrons are systemically investigated.

Abstract
Objective: To investigate the surgical complications in the treatment of stage Ⅰ endometrial cancer by robotic-assisted laparoscopy, the risk degree of Clavein-Dindo complications and the main risk factors affecting the occurrence of surgical complications. Methods: A retrospective case-control study was conducted in the First Affiliated Hospital of Zhengzhou University from October 2014 to June 2019. The patients were divided into robotic-assisted laparoscopy group and traditional laparoscopy group according to the operation mode, including 131 cases in robot group and 290 cases in traditional laparoscopy group. To compare the complications during and after operation and the risk degree of complications between the two groups by Clavein-Dindo classification standard, the age, body mass index (BMI), comorbidities, past history of pelvic surgery, American Society of Anesthesiologists (ASA) grade, preoperative anemia, number of pelvic lymph node resection, number of abdominal aortic lymph node resection, the total number of lymph node resection, operation time, surgical methods (robot surgery or traditional laparoscopic surgery) and other clinicopathological data were analyzed by logistic regression analysis. Results: (1) Complications of operation: the incidence of operative complications (including intraoperative and postoperative complications) in robot group was significantly lower than that in traditional laparoscopy group [(20.6%, 27/131) vs (34.8%, 101/290); χ(2)=8.620, P=0.003)]. The incidence of intraoperative complications in robot group was lower than that in traditional laparoscopy group [1.5% (2/131) vs 6.2% (18/290); χ(2)=4.368, P=0.037]. The incidence of intraoperative vascular injury in robot group was significantly lower than that in traditional laparoscopy group [0.8% (1/131) vs 5.2% (15/290); χ(2)=4.798, P=0.022]. The incidence of postoperative complications in robot group was also lower than that in traditional laparoscopy group [19.1% (25/131) vs 28.6% (83/290); χ(2)=4.303, P=0.038], but the incidence of postoperative lymphatic leakage in robot group was higher than that in traditional laparoscopy group [10.7% (14/131) vs 5.2% (15/290); χ(2)=4.279, P=0.039]. (2) Clavein-Dindo classification: the incidence of Clavein-Dindo Ⅰ, Ⅲ, Ⅲ, Ⅳ and Ⅴ grade between two groups were respectively 3.8% (5/131) vs 11.0% (32/290), 13.7% (18/131) vs 14.5% (42/290), 3.1% (4/131) vs 8.6% (25/290), 0 (0/131) vs 0.3% (1/290), 0 (0/131) vs 0.3% (1/290), and the incidence of grade Ⅰ (χ(2)=5.684, P=0.015) and Ⅲ (χ(2)=4.361, P=0.037) complications were statistically significant. The incidence of severe complications in robot group (grade Ⅲ and above) was lower than that in traditional laparoscopy group [3.1% (4/131) vs 9.3% (27/290); χ(2)=5.179, P=0.023]. (3) Analysis of influencing factors of surgical complications: univariate analysis showed that BMI (χ(2)=15.801, P=0.000), preoperative anemia (χ(2)=14.299, P=0.000), total number of lymph node resection (χ(2)=10.425, P=0.001), surgical methods (χ(2)=8.620, P=0.003) were related to the occurrence of surgical complications of endometrial carcinoma. Multivariate analysis showed that BMI (OR=0.289, 95%CI: 0.097-0.864, P=0.026), preoperative anemia (OR=0.309, 95%CI: 0.129-0.740, P=0.008), the total number of lymph node resection (OR=0.624, 95%CI: 0.403-0.966, P=0.034) and surgical methods (OR=3.491, 95%CI: 1.030-11.840, P=0.045) were independent risk factors for surgical complications of endometrial carcinoma. Conclusions: Compared with traditional laparoscopic surgery, robot-assisted laparoscopic surgery has fewer complications and lower incidence of severe complications. BMI, preoperative anemia, the total number of lymph node resection and surgical methods are independent risk factors for the occurrence of surgical complications of stage Ⅰ endometrial cancer.

Abstract
The efficiency of the microwave-plasma coupling is a key issue to enhance the performance of electron cyclotron resonance ion sources (ECRISs) in terms of higher ion beam intensity yield. The coupling properties are affected by the microwave coupling scheme, especially for the high frequency (f > 20 GHz) and high power (P > 5 kW) ECR ion sources. Based on the study of 24 GHz SECRAL ion source performances working at different launching systems, a new microwave coupling scheme, called the Vlasov launcher, is proposed, which can not only realize efficient power matching and feeding but also enhance the microwave power distribution on the ECR surface. The first promising results are presented in this article. Then, a prototype dedicated to the next generation ECRIS is described.

Abstract
Objective: To observe the expressional changes in Notch signaling pathway and toll-like receptor 4 (TLR4) and their interactions on the functions of CD14(+) monocytes in chronic hepatitis C patients. Methods: A total of 24 treatment-naïve chronic hepatitis C cases and 10 healthy individuals, who visited Shaanxi Provincial People's Hospital from August to October 2017, were enrolled. Selected CD14(+) monocytes were stimulated by the Notch signaling pathway inhibitor DAPT or transfected with TLR4 siRNA, and the levels of Notch1, Notch2, Hes1 and Hes5 mRNA were detected by real-time quantitative PCR. TLR4 protein levels and phosphorylation of NF-κB was detected by Western blot. ELISA was used to detect the level of cytokines secreted from CD14(+) monocytes. A t-test or paired t-test was used for comparison between groups. Results: The relative expression of Notch1 mRNA (3.97 ± 2.03 vs. 0.91 ± 0.76, P < 0.01) and downstream of Notch signaling pathway (5.96 ± 2.31 vs. 0.99 ± 0.45, P < 0.01), Hes1 mRNA and Hes5 mRNA (4.31 ± 1.05 vs. 0.84 ± 0.20, P < 0.01) in CD14+ monocytes of chronic hepatitis C patients was significantly higher than that of healthy individuals. The relative expression of TLR4 mRNA (5.14 ± 1.09 vs. 1.27 ± 0.39) and protein level in CD14(+) monocytes of chronic hepatitis C patients were significantly higher than those of healthy individuals (P < 0.01). An inhibition of Notch signaling pathway with DAPT had reduced the relative expression level of TLR4 mRNA (2.58 ± 1.36 vs. 4.34 ± 1.88, P < 0.05), protein expression and phosphorylation of NF-B in CD14(+) monocytes of chronic hepatitis C patients. Furthermore, the secretion level of MCP-1 [(94.32 ± 23.59) pg/ml vs. (64.07 ± 9.39) pg/ml, P < 0.01] and IL-8 [(12.54 ± 4.89) pg/ml vs. (7.92 ± 3.01) pg/ml, P < 0.05] was significantly reduced. TLR4 siRNA transfection reduced the expressions of Notch1 mRNA (2.09 ± 1.72 vs. 3.73 ± 1.75, P < 0.05), Hes1 (2.87 ± 0.84 vs. 5.54 ± 0.97, P < 0.01), and Hes5 (2.89 ± 0.93 vs. 4.51 ± 1.54, P < 0.01) in CD14(+) monocytes of chronic hepatitis C patients. Conclusion: Interaction of Notch signaling pathway with TLR4 can promote the function of CD14(+) monocytes in chronic hepatitis C patients.

Abstract
Objective: To investigate the clinicopathological features, treatment and prognosis of leiomyomatosis peritonealis disseminata (LPD). Methods: A total of 10 patients suffered from LPD after laparoscopic uterine myomectomy were collected in the First Affiliated Hospital of Zhengzhou University from September 2012 to September 2016, and all clinical database were retrospectively analyzed. Results: (1)Clinical features: the age of 10 cases was 25-50 years old, and 8 cases of them were in child-bearing age, while 2 cases were in perimenopausal period. Of 10 cases, 2 cases manifested as discontinuous lower abdominal pain, and the other cases were seen the doctor for the examinations found tumors of pelvis or abdomen. All 10 cases had a history of laparoscopic uterine myomectomy under went power morcellation with an average of (4.0±2.2) years (range 1.3 to 8.1 years), 2 cases of them had a history of oral hormone treatment after the first myoma morcellation. (2) Treatment methods and postoperative pathologic diagnosis: during intraoperative exploration, LPD nodules were most distributed in Douglas pouch (10 cases), and next in mesentery (7 cases), abdominal peritoneum (6 cases) and omentum majus (4 cases), etc. Seven of the 8 cases of child-bearing age were performed laparoscopic LPD nodules removal, 1 case gone combined with laparotomy and resecting LPD nodules; 2 cases in perimenopausal period done laparotomy oophorotomy and resected all LPD nodules and omentum. (3) Postoperative relapse and reproductive outcomes: the follow-up time of all cases was 2.8 years, and no recurrence was found during the follow-up period; 2 cases had natural conception and term vaginal birth during the follow-up period. Conclusions: LPD is mainly related to iatrogenic planting and spreading, which is a benign disease and characterized by multiple smooth muscle nodules throughout abdominopelvic cavity, and the nodules of LPD is commonly located in Douglas pouch, mesenteric and omentaum majus, etc. The preferred method of LPD should be individual operative treatment according to different situations, and in which patients may be have better prognosis.

Abstract
A novel allelic variant in HLA-B*40 lineage, HLA-B*40:298:02, has been identified in an individual of Han ethnicity afflicted with nasopharyngeal carcinoma in Hunan province, southern China. Following polymerase chain reaction-Sanger sequence-based typing (PCR-SBT), this new variant was further confirmed by two distinct strategies of cloning and sequencing. HLA-B*40:298:02 differs from HLA-B*40:298:01 by a single synonymous cytosine substitution at nucleotide position 26 (T→C) in exon 3, which corresponds to codon 99 of the mature HLA-B mRNA molecule. This new allele has an estimated frequency of 0.0002, in about 2,500 sequence-based typed subjects from the same population.

Abstract
Objective: To analyze the application of vascular replacement technique with allogenic blood vessel in radical resection for pancreatic carcinoma. Methods: The clinical data of 33 patients with vascular invasion of pancreatic carcinoma who underwent radical resection from April 2013 to April 2017 in Department of Hepatobiliary Surgery, Beijing Chaoyang Hospital were retrospectively analyzed. There were 14 males and 19 females with age of (62.5±10.6)years(ranging from 35 to 78 years). Vascular replacement technique with allogenic blood vessel was used on all patients who underwent radical resection for pancreatic carcinoma. The operation procedure was made according to the specific location of the carcinoma, and the allogenic blood vessel was selected according to the type of vascular invasion. The matching vessel was selected for replacement to the patient who was invaded only one vessel. And the "Y" type of iliac vein was selected for replacement to the patient who was invaded the confluence of portal vein, splenic vein and superior mesenteric vein. After the operation, the patients were followed up by telephone and outpatient review. Results: All of 33 patients were successfully completed the operations. There were 28 patients underwent pancreaticoduodenectomy with vascular replacement, and 5 patients underwent total pancreatectomy with vascular replacement. All the patients were confirmed pancreatic carcinoma and R0 resection according to the postoperative pathology. There were 16 patients with the carcinoma invasion the confluence of portal vein, splenic vein and superior mesenteric vein, 12 patients with the carcinoma invasion the superior mesenteric vein, and 5 patients with the carcinoma invasion the portal vein. There was no perioperative death in this group and no complications related to allogenic blood vessel. The incidence of postoperative complications was 18.2% (6/33), and the incidence of pancreatic fistula was 6.1% (2/33), all of which were biochemical fistula. There were 32 patients were followed up, and the follow-up rate was 96.9%. The median survival time was 14.6 months. The half-year, 1-year and 2-year survival rates were 75.6%, 37.6% and 27.4%. Conclusion: The application of vascular replacement technique with allogenic blood vessel for pancreatic carcinoma has a great significance for improving the R0 resection rate and the prognosis of patients.

Abstract
Objective: To investigate the relationship between serum uric acid (SUA) levels and high sensitive C-reactive protein (hs-CRP) in patients with type 2 diabetes mellitus (T2DM). Methods: A total of 400 patients who were hospitalized in the Department of Endocrinology and Metabolism of Jinshan Branch, Shanghai Sixth People's Hospital between April 2014 and December 2015 were divided into normouricemia (NUA, n=319) group and hyperuricemia (HUA, n=81) group according to the presence of HUA. Clinical features of the two groups were compared. Patients were further stratified into quartiles based on SUA levels, and then association between hs-CRP and SUA was analyzed. Results: Compared to the NUA group, the patients with HUA had higher hs-CRP concentration [2.12 (1.15, 6.73) mg/L vs 1.14 (0.52, 3.44) mg/L, P<0.001], erythrocyte sedimentation rate (ESR) [19.0 (10.5, 29.5) mm/h vs 12.0 (8.0, 17.0) mm/h, P<0.001], body mass index (BMI) [(25.2±3.6) kg/m(2) vs (23.6±3.6) kg/m(2,) P<0.001], and homeostasis model assessment-2 of insulin resistance (HOMA2-IR) index [1.88 (1.11, 2.94) vs 1.27 (0.77, 2.00), P<0.001]. After adjusting for age, the median level of hs-CRP of female with HUA was higher than that of male, female with NUA, and male with NUA (2.59, 1.94, 1.25 and 1.09 mg/L, respectively, P<0.001). There was significant difference in the prevalence of HUA among the patients with underweight, normal weight, overweight, and obesity (0, 12.3%, 21.6% and 25.8%, respectively, P=0.002). After adjusting for age and gender, duration of diabetes, BMI, serum lipids, level of SUA was still correlated with hs-CRP, HOMA2-IR, fasting C-peptide, blood urea nitrogen, serum creatinine, Cystatin C, microalbuminuria, respectively(all P<0.05). The level of SUA was positively associated with the increase of hs-CRP level (P=0.001). Multiple linear regression analysis showed that there was an independent and positive association between SUA and hs-CRP levels. Conclusion: SUA was independently associated with hs-CRP in T2DM patients, which suggested that chronic inflammation exists in HUA patients.

Abstract
We investigated the effects of combined targeted gene therapy on recurrence and metastasis after liver cancer resection in nude mice. Twenty BALB/C mice were randomly divided into control and treatment groups with 10 mice in each group and a male/female ratio of 1:1. Luciferase gene-labeled human primary hepatic carcinoma cell line MHCC97-H was then used to prepare a carcinoma model. An optical in vivo imaging technique (OIIT) was used 10 days later to detect the distribution of tumor cells, followed by partial liver resection and gene therapy. In the treatment group, 100 mL phosphate-buffered saline (PBS) containing 1 x 1012 rAAV/AFP/IL-24 gene viral vectors was injected into liver sections and peritumoral posterior peritoneal tissues; in the control group, the same amount of PBS containing 1 x 1012 empty viral vectors was injected at the same sites. OIIT was then used to detect the in vivo tumor metastasis 21 days later. Luciferase gene-labeled human primary hepatic carcinoma cell line MHCC97-H successfully infected 20 nude mice, and OIIT showed that the two groups exhibited metastasis after local tumor resection, but there were more tumor cells in the control group (P < 0.05). rAAV/AFP/IL-24 gene therapy can inhibit recurrence after liver cancer resection.

Abstract
We present an unusual case of an unstable pelvic fracture during pregnancy period, who suffered fetal death and splenic rupture simultaneously which developed massive delayed hemorrhage in abdomen. When considering potential causes of fetal death, direct trauma to the uterus, placenta, or fetus was not associated with a higher fetal mortality rate, compared with maternal hemorrhage. A cesarean section and splenectomy could rescue the maternal life from the hemorrhage situation. Successful treatment of these rare cases is possible with careful pre-, peri-, and post-operative evaluation of the mother and fetus by a multidisciplinary team.

Abstract
Background Extra-nodal marginal zone B cell lymphoma of mucosa-associated lymphoid tissue originating in the liver is less common. Case presentation We described the clinical presentation, immunohistochemistry, and immunophenotypes of this lymphoma, which was misdiagnosed with tiny hepatic carcinoma in a 44-year-old woman with hepatitis C; the patient underwent left lateral sectionectomy. The immunophenotype identified the most of the lymphoid cells as positive CD20, CD34, Ki67, CD3, CD4, CD79a, CD45RO, MUM-1, and CD5 and negative CD10, CD15, CD30, ACT, CK, CRO, DES, and HMB45. The diagnosis of primary hepatic mucosa-associated lymphoid tissue (MALT) was made by histology after surgery; the patient went through the excellent recovery with no chemotherapy and is disease free for 27 months. Conclusions Primary hepatic MALT is less common with incidental finding; local resection is beneficial due to its oncological indolence.

In this report, we present a novel HLA-A*02:07 allele, HLA-A*02:07:08. HLA-A*02:07:08 was identified in an individual of Han ethnicity in Hunan province, southern China. Following polymerase chain reaction-sequence-based typing (PCR-SBT), this new allele was further confirmed by cloning and sequencing. HLA-A*02:07:08 differs from HLA-A*02:07:01 by a single synonymous C to T substitution at nucleotide position 131 in exon 3.

Abstract
We investigated azoospermia region microdeletions in male infertility patients with Klinefelter syndrome (KFS), as well as the association between azoospermia symptoms in patients with KFS and Y chromosome microdeletion polymorphisms. A total of 111 cases with male infertility confirmed to have KFS (47, XXY) and 94 fertile men were included in this study. Peripheral blood was drawn and DNA was extracted from these samples. Multiplex polymerase chain reaction was performed to screen the partial deletions of 25 sequence-tagged sites on the Y chromosome. In 111 cases with KFS, 1 case contained the AZFb+d+c deletion. The Gr/Gr deletion was identified in 12 KFS cases and 5 control cases. In addition, the b2/b3 deletion was identified in 13 KFS cases and 6 control cases. There were no significant differences in phenotype and genotype of the 2 partial AZFc deletions between patients and controls (P > 0.05). Our results suggest that patients with KFS may also have Y chromosome microdeletions to varying degrees and that the gr/gr deletion and b2/b3 deletion may not play a role in the susceptible genetic background of azoospermia in patients with KFS in the Sichuan population.

Abstract
OBJECTIVE This study aims to investigate the protective and sensitive effects of melatonin (MLT) in the treatment of breast cancer. MATERIALS AND METHODS ER+ breast cancer rat model was established and then rats were randomly divided into five different groups as follows: control group, Diss group, adriamycin (ADM) group, MLT group, and MLT combined with adriamycin (M+A) group. Tumor weights and one month survival rate were compared among these groups. In addition, changes of tumor tissues and expression of E-cadherin were observed under optical microscopy or electro-microscopy. RESULTS Tumor weights were significantly lighter in M+A group than those in ADM group (p < 0.05). Under optical and electro-microscopy, tumor cell apoptosis was obviously increased in MLT group, and tumor cell injury was more severe in M+A group than that in ADM group; additionally, expression of E-cadherin was higher in MLT group and M+A group than that in other groups. Moreover, MLT group had the highest one month survival rate (100%), there was the poorest life quality in ADM group, but the best life quality in MLT. CONCLUSION MLT could enhance the sensitivity of tumor to ADM in vivo and improve patient's life quality.

Abstract
We investigated the molecular genetic mechanism of sex reversal by exploring the relationship between mutations in the sex-determining genes SRY, SOX9, and DAX1 with genetic sex reversal disease. Mutations in the three key genes were detected by polymerase chain reaction (PCR) and sequencing after karyotype analysis. The mutations detected were then aligned with a random sample of 100 normal sequences and the NCBI sequence database in order to confirm any new mutations. Furthermore, the copy number of SOX9 was measured by fluorescence quantitative PCR. Seven of the 10 male sex reversal patients (46, XX) contained an excess copy of the SRY gene, while one of the eight female sex reversal patients (46, XY) was lacking the SRY gene. Additionally, a new mutation (T-A, Asp24Lys) was detected in one female sex reversal patient (46, XY). No other mutation was detected in the analysis of SOX9 and DAX1, with the exception of an insertion mutation (c.35377791insG) found in the testicular-specific enhancer (TESCO) sequences in an SRY-positive female sex reversal patient (46, XY). Eight of the 18 sex reversal cases (44.4%) showed obvious connections with SRY gene translocations, mutations, or deletions, which was significantly higher than that reported previously (33.3%), indicating a need to further expand the range of sample collection. Overall, these results indicated that the main mechanism of sex reversal are not associated with mutations in the coding regions of SOX9 and DAX1 or copy number variations of SOX9, which is consistent with results of previous studies.

Abstract
The purpose of this study was to detect chromosomal aberrations and azoospermia factor (AZF) microdeletions in male patients with reproductive problems and to summarize related clinical features to provide reliable information for evaluating prenatal and preimplantation diagnoses. A large cohort of 5083 men with various phenotypes of male infertility was analyzed via G-banding karyotyping, and Origin 8.0 was used to analyze the prevalence of abnormalities. Additionally, patients with azoospermia, oligozoospermia, and oligoasthenozoospermia were analyzed using multiplex polymerase chain reaction to detect microdeletion in the AZF. We identified 387 patients with abnormal karyotypes, and the ratio was 7.61%. Among them were 175 patients with Klinefelter's syndrome, which was the most common numerical chromosomal abnormality and accounted for 45.22% of all chromosomal aberrations. The frequencies of increased satellites, balanced translocations, and Robertsonian translocations were 6.47, 7.00, and 3.62%, respectively. Multiplex polymerase chain reaction performed in 810 cases with azoospermia, oligozoospermia, and oligoasthenozoospermia found a ratio of AZF microdeletions of 4.94%. The finding suggests that chromosomal abnormalities and AZF deletion are main factors that result in male infertility. Detecting these common genetic variations is necessary in infertile men seeking assisted reproductive technology.

Abstract
OBJECTIVE We aimed to measure separately the contributions of heat and humidity to changes in levels of 34 markers of inborn disorders in dried-blood-spot (DBS) samples. DESIGN AND METHODS We stored paired sets of DBSs at 37°C for predetermined intervals in low-humidity and high-humidity environments. Marker levels of all samples in each complete sample set were measured in a single analytic run. RESULTS During the 30 ± 5 day studies, galactose-1-phosphate uridyltransferase and biotinidase lost almost 65% of initial activities in low-humidity storage; most of the degradation in 27 other markers was attributable to adverse effects of high-humidity storage; seven markers in DBSs stored at high humidity lost more than 90% of initial levels by the end of the study and 4 of the 7 lost more than 50% of initial levels within the first week of storage. CONCLUSIONS Minimizing both humidity and temperature in DBS transportation and storage environments is essential to maintaining sample integrity.

Abstract
In this study, the capacity of bone morphogenetic protein 2 (BMP-2) gene-transfected bone marrow-derived mesenchymal stem cells (MSCs) in combination with nano-hydroxyapatite/collagen/poly(L-lactic acid) (nHAC/ PLA) to improve the repair of bone defects in rabbit was explored. MSCs from New Zealand White rabbits were cultured and injected with pIRES2-EGFPhBMP-2 or pIRES2-EGFP by electroporation. After the transfer efficiency was determined through the expression of EGFP, the MSCs were seeded on scaffolds to generate an in vitro 3D cell/scaffold construct. The adhesion and proliferation of the MSCs cultured in the scaffold was assessed by SEM. The cellular constructs obtained were allografted into the 15 mm critical-sized segmental bone defects in the radius of New Zealand White rabbits for 12 weeks. The bone regeneration was assessed by radiographical and histological analyses. In vitro, nHAC/PLA facilitated MSC adhesion and proliferation on the scaffold, and gene transfer efficiency reached a maximum of 35.5 ± 3.8%. In vivo, the implantation of BMP-2 transfected MSCs/nHAC/PLA construct significantly enhanced the formation of new bone in the segmental defect, compared to the control groups. This novel 3D BMP-2 transfected MSCs/nHAC/PLA construct has the potential for bone repair by genetic tissue engineering approach.

Abstract
The objectives of this study were to determine the effect of tumor necrosis factor alpha (TNF-alpha) on intestinal epithelial cell permeability and the expression of tight junction proteins. Caco-2 cells were plated onto Transwell microporous filters and treated with TNF-alpha (10 or 100 ng/mL) for 0, 4, 8, 16, or 24 h. The transepithelial electrical resistance and the mucosal-to-serosal flux rates of the established paracellular marker Lucifer yellow were measured in filter-grown monolayers of Caco-2 intestinal cells. The localization and expression of the tight junction protein occludin were detected by immunofluorescence and Western blot analysis, respectively. SYBR-Green-based real-time PCR was used to measure the expression of occludin mRNA. TNF-alpha treatment produced concentration- and time-dependent decreases in Caco-2 transepithelial resistance and increases in transepithelial permeability to the paracellular marker Lucifer yellow. Western blot results indicated that TNF-alpha decreased the expression of phosphorylated occludin in detergent-insoluble fractions but did not affect the expression of non-phosphorylated occludin protein. Real-time RT-PCR data showed that TNF-alpha did not affect the expression of occludin mRNA. Taken together, our data demonstrate that TNF-alpha increases Caco-2 monolayer permeability, decreases occludin protein expression and disturbs intercellular junctions.

Abstract
In this study, we investigated human leukocyte antigen (HLA)-G*0105N and the 14 bp deletion/insertion polymorphism in exon 8 of the HLA-G gene in 600 individuals from two southern Chinese Han populations (Hunan Han and Guangdong Han) and two northern Chinese populations (Inner Mongolia Han and Inner Mongolia Mongol), we also studied the linkage disequilibrium (LD) between HLA-G and HLA-A locus in these four populations. Our data showed that (1) the allele and haplotype frequencies of HLA-G and HLA-A loci did not differ significantly between the two southern Chinese Han populations, and showed remarkable homogeneity in the two northern Chinese populations; (2) HLA-G*0105N had significantly higher frequencies in the two northern Chinese populations with a frequency of 10.1% in the Inner Mongolia Han population, HLA-G 14 bp deletion/insertion frequency did not differ significantly between the southern and northern Chinese populations; (3) Ewens-Watterson homozygosity statistics at HLA-G*0105N, HLA-G 14 bp deletion/insertion polymorphism and HLA-A were consistent with neutral expectations for all populations; (4) HLA-G*0105N allele harbored the HLA-G 14 bp insertion in exon 8 and was linked to HLA-A*30, five HLA-G*0105N homozygotes were detected in the four populations; (5) haplotypes HLA-A*30-HLA-G*0105N and HLA-A*02-HLA-G 14 bp deletion were in significant LD across four populations, other LD patterns were more population-specific. Our data suggest that HLA-A*30-HLA-G*0105N-HLA-G 14 bp insertion is a conserved haplotype, the ethnic and/or geographic difference in HLA-G*0105N and HLA-G 14 bp distribution could largely be attributable to demographic factors other than selection. The LD patterns uncovered will facilitate the understanding of HLA-G role in associations previously described between HLA-A subregion and diseases.

Abstract
We have characterized gene dysfunction in a cellular model of spontaneous canine mammary cancer by investigating specific gene defects in SIRT2 and p53 genes for comparative studies among canine tumour-derived cell lines. These genes and their downstream targets are involved in regulating gene silencing, cell cycle progression and prevention of senescence and apoptosis. Canine SIR2 reverse transcriptase-polymerase chain reaction amplicons were most homologous to human SIRT2 and revealed detectable transcripts in all cell lines. Canine SIRT2 contained non-conserved amino acid substitutions, representing mutations or allelic differences and interspecies differences. Sequence differences between individuals in p53 and SIRT2 were found in two cell lines including a stop codon in p53 and substitutions of conserved cysteine residues in the Zn(2+)-binding motif in SIRT2. Mutations in SIRT2 were coincident with expression of the p53 modulator, Wip1; a failure to activate p21/Cip1 and extended G2/M phase. A third cell line appeared to function normally in these two pathways and likely possesses other defects in proliferation-control genes. This data identify potentially important defects in pathways regulated by p53 and SIRT2 that modulate cell proliferation and integrate development, apoptosis and proliferative lifespan. These genes offer promising therapeutic targets, contributing to the transformed/immortalized phenotype in spontaneous canine mammary cancer.

Abstract
BACKGROUND While providing potent immunosuppression for liver transplant recipients, calcineurin inhibitors (CNI) exhibit nephrotoxicity as a major side effect. The purpose of this study was to evaluate the safety and efficacy of conversion from CNI to sirolimus (SRL) among liver transplant recipients with CNI-induced chronic nephrotoxicity. METHODS Between January 2004 and June 2005, we performed conversion in 16 recipients after a median period of 8.5 months after liver transplantation. The indication for conversion was CNI-related nephrotoxicity with a serum creatinine (sCr) value >132.6 umol/L. Renal function was measured before and after conversion to SRL. Clinical and laboratory data related to the clinical course of the patients were recorded to investigate the safety and efficacy of conversion. RESULTS Sixteen patients were converted to SRL after developing nephrotoxicity. Their renal function improved gradually after conversion. The levels of sCr decreased significantly within the first 30 days (164.1 +/- 12.48 micromol/L to 130.1 +/- 5.573 micromol/L), and over the next 60 days after conversion (97.86 +/- 11.69 micromol/L to 90.7 +/- 8.95 micromol/L) (P < .01). Similarly, the mean glomerular filtration rate (GFR) increased significantly during the same period. Four recipients experienced hypercholesterolemia, 1 with ankle edema, and 1 with acute rejection. The median follow-up was 2.4 years. No patient discontinued SRL due to side effects. No patient needed dialysis or kidney transplantation during the study period. CONCLUSIONS SRL is a safe, effective replacement agent as primary immunosuppressive therapy following withdrawal of CNIs in liver transplant recipients with CNI-induced chronic nephrotoxicity.

Abstract
Macrophages are the main source of cytokines in atherosclerotic plaques. Modified low-density lipoproteins may stimulate macrophages to produce large quantities of proinflammatory cytokines that promote atherosclerosis. Berberine is the main component of the traditional Chinese medicine umbellatine, which has a widespread effect and was used to treat many diseases clinically. Our previous study found that berberine could increase adipophilin expression in macrophages, which is a target gene of PPARgamma. PPARgamma agonist could decrease proinflammatory cytokines in macrophage. In this study, we investigated the effects and the mechanism of action of berberine on the expression and secretion of TNFalpha, MCP-1, and IL-6 in vitro to identify new pharmacological actions of berberine. The results of RT-PCR and ELISA shows that berberine may inhibit the expression and secretion of the tumor necrosis factor alpha (TNFalpha), monocyte chemoattractant protein 1 (MCP-1), and interleukin-6 (IL-6) in macrophages stimulated by acetylated low-density lipoprotein (AcLDL), whereas the peroxisome proliferator-activated receptor gamma (PPARgamma) inhibitor GW9662 could attenuate this effect of berberine. This study demonstrates that berberine may inhibit the expression and production of TNF-alpha, MCP-1, and IL-6 in AcLDL-stimulated macrophages. This effect might be partially mediated through PPARgamma activity.
