Abstract
The leakage neutron spectra from three different sizes of Lead samples were measured by a TOF technique at 60° and 120°. The essential characteristic properties of the experimental measurement spectra can be reproduced well by MCNP code simulations with the ENDF/B-VIII.0, CENDL-3.2, JENDL-5.0, JEFF-3.3 and TENDL-2021 evaluated nuclear data libraries. The calculated results of JENDL-5.0 and JEFF-3.3 libraries agree better with the experimental data in the whole energy range. The results from ENDF/B-VIII.0 and CENDL-3.2 are overestimated in the 4-9 MeV range at 60° and in the 4-12.5 MeV range at 120°. The differences of the leakage neutron spectra by MCNP simulations using five evaluated nuclear data libraries mainly originate from the differences of the spectrum distributions of neutron reaction channels in these libraries. And the secondary neutron energy distribution and angular distribution from the five libraries have been present to explain it.

Abstract
Objective: To compare the clinical effects of single-incision robot-assisted laparoscopic radical prostatectomy (RARP) with and without extraperitoneal special channel device. Methods: The clinical data of 70 patients who had undergone RARP in the Robotic Minimally Invasive Surgery Center of Sichuan Provincial People's Hospital from September 2020 to February 2021 were analyzed retrospectively, including 29 cases who were operated on without special channel device (group A) and 41 cases with special channel device (group B). All operations were performed by robot-assisted single-incision retrograde bladder neck exfoliation via extraperitoneal approach in patients by the same operator. The operation time, intraoperative blood loss, the bladder neck urethral anastomosis time, postoperative hospital stay, postoperative exhaust time, positive rate of incisal margin, indwelling time of urinary catheter, retention rate of postoperative erectile function, satisfaction rate of immediate postoperative urine control, positive rate of postoperative lymph node pathology, incision length, treatment cost and the rate of prostate specific antigen (PSA)lower than 0.2 μg/L at 6 weeks after operation were compared between the two groups. Results: All 70 cases were operated successfully. The difference of age[ (68.9±3.9) vs (69.4±5.4) years], preoperative PSA level[14.1(6.3, 19.8)vs13.7(5.8, 18.1)μg/L], prostate volume[44.8(30.7,172.6)vs 56.3(40.9,163.4)ml ] of the two groups was not statistically significant(all P>0.05). The difference of operation time [ (59.1±18.5) vs (59.6±18.0) min ], intraoperative blood loss [93(66,198)vs 95(68,203) ml ], bladder neck urethral anastomosis time [ (12.6±1.3) vs (13.7±2.8) min ], postoperative hospital stay [ (8.1±2.3) vs (9.1±1.3) d], postoperative exhaust time [ (1.4±0.6) vs (1.3±0.6) d], positive rate of incisal margin (20.7% vs 19.5%), indwelling time of the urinary catheter after operation [ (6.8±1.5) vs (7.1±2.0) d ], the retention rate of postoperative erectile function (31.0% vs 27.0%), the satisfaction rate of immediate postoperative urine control (79.3% vs 75.6%), the positive rate of postoperative lymph node pathology (17.2% vs 14.6%), the length of incision [ (5.1±0.5) vs (6.1±0.4) cm ], the rate of PSA lower than 0.2 μg/L at 6 weeks after operation (86.2% vs 83.0%) of the two groups was not statistically significant(all P>0.05). The operation cost of group A[(62 000±4 000) yuan]was lower than group B[(68 000±4 000) yuan] (P<0.05). Conclusion: Extraperitoneal non-special channel device single-incision RARP is safe and feasible.

Abstract
Objective: To investigate the predictive value of myoglobin (Mb) for the prognosis of sepsis related chronic critical illness (CCI). Methods: Retrospective study was conducted on septic patients with the length of ICU stay equal or greater than 14 days, and sepsis-related organ failure assessment (SOFA) score equal or greater than 2 on the 14th day in ICU in the First Department of Critical Care Medicine at the First Affiliated Hospital of Sun Yat-sen University from January 2017 to March 2020. Patients' clinical and laboratory data were collected on the 1st and 14th day in ICU. The survival on day 28 in ICU was recorded. According to the myoglobin levels on day 1 and day 14, all subjects were divided into myoglobin elevation group and decline group. Kaplan-Meier survival curve was used to compare the cumulative survival rate at day 28. Cox regression analysis was used to analyze the independent risk factors of mortality. Receiver operating characteristic (ROC) curve was used to analyze the prognostic value of myoglobin. Results: A total of 131 patients with sepsis related CCI were recruited, including 58 patients in the elevation group and 73 in the decline group. The Mb level in elevation group on day 1 was significantly lower than that in decline group [172.40(59.99, 430.53) μg/L vs. 413.60(184.40, 1 328.50) μg/L, Z=3.749, P=0.000], and the Mb level on day 14 was the opposite change in two groups [483.65(230.38, 1 471.75)μg/L in elevation group vs. 132.20(76.86, 274.35)μg/L in decline group, Z=5.595, P=0.000]. Kaplan-Meier survival curve analysis showed that the 28-day cumulative survival rate of the elevation group was significantly lower than that of decline group (χ²=7.051, P=0.008). Cox ratio regression analysis suggested that elevated myoglobin was an independent risk factor for 28-day mortality in septic patients with CCI (OR=2.534, 95%CI 1.212-5.295, P=0.013). ROC curve analysis suggested that the sensitivity of myoglobin elevation in predicting mortality related to CCI within 28 days was 64.5%, and the specificity was 32.0% with area under the curve(AUC) 0.661(95%CI 0.550-0.773,P=0.007) and Jorden Index was 0.325. Conclusion: Elevated myoglobin, an independent risk factor for mortality within 28 days in ICU, can predict the prognosis of sepsis related chronic critical illness.

Abstract
PURPOSE It is difficult to manage the full-thickness defect that is created by radical resection of an abdominal wall tumor. This report aimed to review our institutional experience with immediate reconstruction using mesh reinforcement after abdominal wall tumor resection. METHODS We retrospectively examined patients who underwent abdominal wall tumor resection with immediate mesh-reinforced reconstruction between April 2014 and November 2018. The patients' records were reviewed to collect data regarding their demographic characteristics, surgical procedures, and complications. RESULTS We identified 30 eligible patients, including 5 who underwent simultaneous resection of affected intra-abdominal organs or tissues. The median size of the resulting abdominal wall defect was 60 cm2 (interquartile range: 32-127.5 cm2) and the median mesh size was 150 cm2 (interquartile range: 150-225 cm2). The median operative time was 85 min (interquartile range: 60-133.8 min), the mean hospital stay was 19.4 ± 9.0 days, and the mean follow-up period was 28.6 ± 16.0 months. The complications included seroma (n = 4), infection (n = 2), massive hematoma (n = 1), and abnormal sensation (n = 3). Tumor recurrence was observed in two patients, and three patients died because of cancer progression. No patient developed a ventral hernia or abdominal bulging. CONCLUSION Immediate mesh-reinforced reconstruction is feasible and effective for patients who require abdominal wall tumor resection.

Abstract
The atomic layer deposition (ALD) of high-k dielectrics could build an efficient barrier against moisture and O2 adsorption. Such a barrier is highly needed for MoTe2 and WTe2 transition metal dichalcogenides because of the poor structural stability and the fast oxidization in ambient air. In situ x-ray photoelectron spectroscopy and ex situ atomic force microscopy and scanning transmission electron microscopy were employed to report a comparative study between the growth of Al2O3 on MoTe2 and WTe2 by means of traditional thermal ALD and plasma-enhanced ALD (PEALD). Similar to what has been observed on other 2D materials such as MoS2 and Graphene, the thermal ALD results in an islanding growth of Al2O3 on MoTe2 due to the dearth of dangling bonds, whereas, a uniform coverage of Al2O3 on WTe2 is observed and likely contributed to the high concentration of intrinsic structural defects. The PEALD behavior is consistent between MoTe2 and WTe2 providing a conformal and linear growth rate (∼0.08 nm/cycle), which correlates with the creation of Te-O and metal-O nucleation sites. However, a thin layer of interfacial Mo or W oxides gradually forms, resulting from the plasma-induced damage in the topmost (1-2) layers. Attempts to enhance the Al2O3/MoTe2 interfacial quality by physically evaporating an Al2O3 seed layer are investigated as well. However, the evaporated Al2O3 process causes thermal damage on MoTe2, necessitating a more 'gentle' ALD technique for the surface passivation.

Abstract
Abstract
Background
Previous meta-analyses, through internal, within-study comparisons of women and men participants, have observed that women with diabetes are at substantially higher risk of coronary heart disease (CHD), stroke and gastric cancer compared with affected men. However, the magnitude of the excess risk of these and other cause-specific outcomes that is conferred by diabetes for men and women is unknown.
Purpose
To estimate the relative effect of diabetes on risk of all-cause, cancer, cardiovascular disease (CVD), infectious disease and respiratory disease mortality in women compared with men.
Methods
Studies published from their inception to April 1, 2018, identified through a systematic search of PubMed and EMBASE and review of references. We used the sex-specific RRs to derive the women-to-men ratio of RRs (RRR) and 95% CIs from each study. Subsequently, the RRR for each outcome was pooled with random effects meta-analysis weighted by the inverse of the variances of the log RRRs.
Results
Forty-eight studies with 85 prospective cohorts met the inclusion criteria and were eligible for analysis. The pooled women to men RRR showed a 13% greater risk of all-cause mortality associated with diabetes in women than in men (RRR: 1.13, 95% CI: 1.07 to 1.19; P<0.001, Figure 1). The pooled multiple-adjusted RRR indicated a 30% significantly greater excess risk of CVD mortality in women with diabetes compared with men (RRR: 1.30 95% CI: 1.13 to 1.49; P<0.001). Compared with men with diabetes, women with diabetes had a 58% greater risk of coronary heart disease (CHD) mortality, but only an 8% greater risk of stroke mortality (RRRCHD: 1.58, 95% CI: 1.32 to 1.90; P<0.001; RRRstroke: 1.08, 95% CI: 1.01 to 1.15; P<0.001). However, no sex differences were observed among the population with or without diabetes, for all-cancer (RRR: 1.02, 95% CI: 0.98 to 1.06; P=0.21), infectious (RRR: 1.13, 95% CI: 0.90 to 1.38; P=0.33) and respiratory mortality RRR: 1.08, 95% CI: 0.95 to 1.23; P=0.26).
Conclusions
Compared with men with the same condition, women with diabetes have a 58% and 13% greater risk of CHD and all-cause mortality, respectively. This points to an urgent need to develop sex and gender specific risk assessment strategies and therapeutic interventions that target diabetes management for CHD prevention.

Abstract
Abstract
Aim
This study aimed to develop a nomogram based on clinicopathological features to evaluate the recurrence probability of breast phyllodes tumors following surgery. The criteria for atypia, mitoses, overgrowth, and surgical margin (AMOS) were also validated.
Method
Data from 334 patients with breast phyllodes tumors, who underwent surgical treatment at Sun Yat-sen Memorial Hospital from January 2005 to December 2014, were used to develop a prediction model. Additionally, data of 36 patients from Peking University Shenzhen Hospital and data of 140 patients from Sun Yat-sen University Cancer Center during the same period were used to validate the model. The medical records and tumor slides were retrospectively reviewed. The log-rank and Cox regression tests were used to develop a clinical prediction model of breast phyllodes tumors as well as validating the AMOS criteriaAll statistical analyses were performed using R and STATA.
Results
Of all 334 patients included in the study, 224 had benign, 91 had borderline, and 19 had malignant tumors. The local and distant recurrence rate was 17.7%. The 1-,3-, and 5-year cumulative recurrence-free survival was 98.5%, 97.9%, and 96.8%, respectively. Surgical margin, mitoses, and tumor border were identified as independent risk factors for breast phyllodes tumors. A nomogram was developed based on these three variables. The C-index of internal and external validation was 0.71and 0.67, respectively. The area under the curve of AMOS criteria was 0.59.
Conclusions
The present study model presented a more concise and objective variables to evaluate the recurrence-free survival of patients after surgery compared with that using the AMOS criteria, which is more appropriate for clinical practice and also allows for a more accurate prediction.

Abstract
The aim of this study was to explore the effect of depression of different degrees on inflammatory response and immune function in patients with ovarian cancer. One hundred and eight cases of ovarian cancer according to the Federation Internationale of Gynecologie and Obstetrigue (FIGO) stage II~III who visited the Gynecology Department of Affiliated HongQi Hospital of MuDanJiang Medical University between September 2015 and May 2017 were enrolled in the study. After being hospitalized, they were divided into two groups according to their Beck Depression Inventory (BDI) scores. The total score of BDI is 63, with 0~4 for the normal group (25 cases), 5~13 for the mild depression group (24 cases), 14~20 for the moderate depression group (28 cases), and 21~63 for the severe depression group (31 cases). The immune function, inflammatory reaction, tumor markers [CA125, human epididymis protein-4 (HE4), insulin-like growth factor-I (IGF-I)], platelet technology and D-dimer index were compared between the four groups. The results showed that there were different levels of depression in patients with ovarian cancer in II~III stage, and the degree of depression could stimulate the level of serum-6, and TNF -α in serum increased. The proportion of CD3+, CD4+ and NK cells in patients with severe depression decreased, and their immunity also decreased. Depression increased the levels of CA125, HE4 and IGF-I in serum and ascites of ovarian cancer patients, and increased the risk of tumor progression and recurrence. Hypercoagulability existed in patients with ovarian cancer, and tumor associated depression could increase platelet count in plasma and increase D-dimer level. To sum up, depression can affect the level of micro inflammation in patients with ovarian cancer. In particular, depression can reduce cellular immune responses, affect the progression free survival of ovarian cancer patients, and reduce their overall survival rate.

Abstract
This study aimed to evaluate the feasibility and performance of Arndt-endobronchial blocker (Arndt) combined with laryngeal mask airway (LMA) compared with left-sided double-lumen endobronchial tube (L-DLT) in morbidly obese patients in one-lung ventilation (OLV). In a prospective, randomized double-blind controlled clinical trial, 80 morbidly obese patients (ASA I-III, aged 20-70) undergoing general anesthesia for elective thoracic surgeries were randomly allocated into groups Arndt (n=40) and L-DLT (n=40). In group Arndt, a LMA™ Proseal was placed followed by an Arndt-endobronchial blocker. In group L-DLT, patients were intubated with a left-sided double-lumen endotracheal tube. Primary endpoints were the airway establishment, ease of insertion, oxygenation, lung collapse and surgical field exposure. Results showed similar ease of airway establishment and tube/device insertion between the two groups. Oxygen arterial pressure (PaO2) of patients in the Arndt group was significantly higher than L-DLT (154±46 vs 105±52 mmHg; P<0.05). Quality of lung collapse and surgical field exposure in the Arndt group was significantly better than L-DLT (effective rate 100 vs 90%; P<0.05). Duration of surgery and anesthesia were significantly shorter in the Arndt group (2.4±1.7 vs 3.1±1.8 and 2.8±1.9 vs 3.8±1.8 h, respectively; P<0.05). Incidence of hoarseness of voice and incidence and severity of throat pain at the post-anesthesia care unit and 12, 24, 48, and 72 h after surgery were significantly lower in the Arndt group (P<0.05). Findings suggested that Arndt-endobronchial blocker combined with LMA can serve as a promising alternative for morbidly obese patients in OLV in thoracic surgery.

Abstract
Abstract
Background
Kelch-like 6 (KLHL6) is a cancer oncogene previously associated with specific human cancers, such as chronic lymphocytic leukaemia. Here, the mechanisms of KLHL6 function were explored in gastric cancer (GC) cells, in an in vivo experimental tumour model, and the prognostic value of KLHL6 analysis in GC tissue evaluated in a cohort of patients with GC.
Methods
Associations between clinicopathological and survival data and KLHL6 expression in GC tissues were analysed. The effects of downregulation of KLHL6 in GC cells was investigated using proliferation, invasion, apoptosis and lymphangiogenesis assays, and analysis of tumour growth in an in vivo experimental model.
Results
KLHL6 was upregulated in 43 per cent of GC tissues compared with 5 per cent of paired non-tumour tissues from 84 patients. KLHL6 protein expression in GC tissues was much higher than that in atrophic gastritis, intestinal metaplasia and dysplasia tissues from benign gastric disease samples. KLHL6 expression was positively related to the intestinal Laurén classification in GC tissues. Downregulated expression of KLHL6 in MGC-803 GC cells reduced colony formation, proliferation, viability, migration and invasion, enhanced apoptosis and inhibited the cell cycle in the G1 phase. Downregulated expression of KLHL6 also suppressed tumour growth in mice. Furthermore, downregulated expression of KLHL6 mRNA reduced the expression of nuclear-associated antigen Ki-67, vascular endothelial growth factor C, hepatocyte growth factor and matrix metalloproteinase 2 in vitro, and KLHL6 protein in tumour tissue of mice.
Conclusion
Abnormal expression of the KLHL6 oncogene promoted GC progression in vitro and in vivo, and its expression level in tumour tissue was found to be of prognostic value.

Abstract
OBJECTIVE To evaluate the result of operation and gait analysis at the early stage after direct anterior approach (DAA) in total hip arthroplasty (THA). METHODS In this study, 20 patients who suffered from necrosis of femoral head or developmental dysplasia of the hip were scheduled to undergo THA. The basic information and visual analogue scale (VAS) score, Harris score before and after surgery were recorded. All of the patients finished the gait analysis before the surgery and 6 weeks and 12 weeks after the surgery, the data were compared with those of normal adult people. RESULTS Their hospital stay after the operation was 3.3 d, the VAS score after the operation was no more than 4 points, the positions of prosthesis were satisfactory, and there was no dislocation. The gait analysis results contained step speed, stride, the range of motion (ROM) of hip and knee. The step speed before the surgery (preoperation, Pre) was 0.64 m/s, 6 weeks after the surgery (6W) was 0.77 m/s, 12 weeks after the surgery (12W) was 1.07 m/s, and the control group was 1.19 m/s. The stride at Pre, 6W, 12W, and control group were 43.15 steps/min, 51.42 steps/min, 55.52 steps/min, and 57.15 steps/min, respectively. The ROM of hip joint at Pre, 6W, 12W, and control group were 31.00°, 39.62°, 40.40°, and 45.67°, respectively. The ROM of knee joint at Pre, 6W, 12W, and control group were 50.52°, 59.28°, 67.29°, and 70.42°, respectively. The results of the gait analysis showed that the gait recovery after the direct anterior total hip arthroplasty was very fast and at the 12th week after surgery the gait of the patients was close to the normal adult people. CONCLUSION The direct anterior approach is one of the choosable approach of the THA, and this kind of surgery has a better recovery of gait after the operation, and at the end of 12 weeks after the surgery the gait is very close to the normal adult people. But we also need more studies to prove this conclusion.

Abstract
BACKGROUND Schizophrenia patients have a higher prevalence of type 2 diabetes mellitus with impaired glucose tolerance (IGT) than normals. We examined the relationship between IGT and clinical phenotypes or cognitive deficits in first-episode, drug-naïve (FEDN) Han Chinese patients with schizophrenia. METHOD A total of 175 in-patients were compared with 31 healthy controls on anthropometric measures and fasting plasma levels of glucose, insulin and lipids. They were also compared using a 75 g oral glucose tolerance test and the homeostasis model assessment of insulin resistance (HOMA-IR). Neurocognitive functioning was assessed using the MATRICS Consensus Cognitive Battery (MCCB). Patient psychopathology was assessed using the Positive and Negative Syndrome Scale (PANSS). RESULTS Of the patients, 24.5% had IGT compared with none of the controls, and they also had significantly higher levels of fasting blood glucose and 2-h glucose after an oral glucose load, and were more insulin resistant. Compared with those patients with normal glucose tolerance, the IGT patients were older, had a later age of onset, higher waist or hip circumference and body mass index, higher levels of low-density lipoprotein and triglycerides and higher insulin resistance. Furthermore, IGT patients had higher PANSS total and negative symptom subscale scores, but no greater cognitive impairment except on the emotional intelligence index of the MCCB. CONCLUSIONS IGT occurs with greater frequency in FEDN schizophrenia, and shows association with demographic and anthropometric parameters, as well as with clinical symptoms but minimally with cognitive impairment during the early course of the disorder.

Abstract
We have directly measured the band gap renormalization associated with the Moss-Burstein shift in the perovskite transparent conducting oxide (TCO), La-doped BaSnO_{3}, using hard x-ray photoelectron spectroscopy. We determine that the band gap renormalization is almost entirely associated with the evolution of the conduction band. Our experimental results are supported by hybrid density functional theory supercell calculations. We determine that unlike conventional TCOs where interactions with the dopant orbitals are important, the band gap renormalization in La-BaSnO_{3} is driven purely by electrostatic interactions.

Abstract
The limited success of somatic cell nuclear transfer (SCNT) is largely attributed to defects in epigenetic reprogramming of the donor genome. Donor cell types with distinct potential competence may offer different epigenetic flexibility for subsequent genome reprogramming in SCNT. Stem cells possibly enable their genomes to be more readily reprogrammed than differentiated cells. To improve the efficiency of cloning, porcine mesenchymal stem cells (pMSCs) were isolated and well identified by 6-channel flow cytometry and differentiation assays and were used as donors in SCNT. Compared with porcine embryonic fibroblasts (pEFs), our results showed that pMSCs markedly enhanced cloned embryo development in terms of cleavage and blastocyst formation (p < 0.05). To enhance the epigenetic flexibility of pMSCs, classical reprogramming factors (RFs) were transfected by electroporation, and we achieved optimization with ectopic expression of RFs in pMSCs. Our results suggest that the epigenetic status of donor cells has an improvement on genome reprogramming, and multipotent pMSCs favoured subsequent embryonic development.

Abstract
Chemotherapy is an important treatment modality for gastric cancer (GC); however, it usually fails because of drug resistance, especially multidrug resistance (MDR). Previously, we found a novel subset of MDR-associated microRNAs (miRNAs) through high-throughput functional screening. In this report, we investigated the exact roles and mechanisms of miR-23b-3p in the MDR of GC. Using gain or loss-of-function in in vitro and in vivo experiments, we found that overexpression of miR-23b-3p reversed cancer cell resistance to multiple chemotherapeutics in vitro and sensitize tumors to chemotherapy in vivo. Reporter gene assay and western blot analysis showed that ATG12 and HMGB2 were the direct targets of miR-23b-3p. Meanwhile, ATG12 and HMGB2 were positively associated with the occurrence of autophagy. Reducing the expression of these target genes by siRNA or inhibition of autophagy both sensitized GC cells to chemotherapy. These findings suggest that a miR-23b-3p/ATG12/HMGB2/autophagy-regulatory loop has a critical role in MDR in GC. In addition, miR-23b-3p could be used as a prognostic factor for overall survival in GC. In conclusion, our data demonstrated that miR-23b-3p inhibited autophagy mediated by ATG12 and HMGB2 and sensitized GC cells to chemotherapy, and suggested the potential application of miR-23b-3p in drug resistance prediction and treatment.

Abstract
OBJECTIVE Macrophage activation syndrome (MAS) is a relatively rare but potentially fatal complication of childhood rheumatic illnesses. We sought to provide insight for the timely recognition and diagnosis of MAS and efficacious disease management in adults with rheumatic diseases. METHODS Clinical files for eight adult MAS patients treated at the Second Affiliated Hospital of Harbin Medical University were analyzed for clinical manifestations, laboratory investigations, therapeutic measurements and clinical outcomes. RESULTS The study included male and female patients with ages ranging from 16 to 59 years old. All patients were diagnosed with underlying rheumatic diseases with five patients having adult-onset Still's disease (AOSD), two patients having systemic lupus erythematosus (SLE) and one patient having Sjögren's syndrome (SS). The interval from fever onset to MAS diagnosis varied from seven days to 40 days. The most common clinical presentations were prolonged high fever, respiratory symptoms and jaundice. No patients had symptoms involving the central nervous system (CNS). Laboratory findings showed peripheral cytopenias, elevated liver enzymes, elevated triglycerides, hypofibrinogenemia and bone marrow hemophagocytosis. Potential effective treatments for MAS include glucocorticoid plus immunoglobulin therapy, but delays in diagnosis and treatment may lead to a fatal disease course. CONCLUSION MAS in adults may not be as rare as was once thought, although the clinical features of MAS in adults often differ from those seen in children. The MAS mortality in adults is far higher than that for children. A diagnosis of MAS should be considered when a patient with rheumatic disease presents with prolonged high fever, peripheral cytopenia and liver failure. Collection of bone marrow aspirates is critical for accurate diagnosis and MAS therapy should begin as early as possible.

Abstract
Metastasis is a major clinical obstacle in the treatment of gastric cancer (GC) and it accounts for the majority of cancer-related mortality. MicroRNAs have recently emerged as regulators of metastasis by acting on multiple signaling pathways. In this study, we found that miR-7 is significantly downregulated in highly metastatic GC cell lines and metastatic tissues. Both gain-of-function and loss-of-function experiments showed that increased miR-7 expression significantly reduced GC cell migration and invasion, whereas decreased miR-7 expression dramatically enhanced cell migration and invasion. In vivo metastasis assays also demonstrated that overexpression of miR-7 markedly inhibited GC metastasis. Moreover, the insulin-like growth factor-1 receptor (IGF1R) oncogene, which is often mutated or amplified in human cancers and functions as an important regulator of cell growth and tumor invasion, was identified as a direct target of miR-7. Silencing of IGF1R using small interefering RNA (siRNA) recapitulated the anti-metastatic function of miR-7, whereas restoring the IGF1R expression attenuated the function of miR-7 in GC cells. Furthermore, we found that suppression of Snail by miR-7, through targeting IGF1R, increased E-cadherin expression and partially reversed the epithelial-mesenchymal transition (EMT). Finally, analyses of miR-7 and IGF1R levels in human primary GC with matched lymph node metastasis tissue arrays revealed that miR-7 is inversely correlated with IGF1R expression. The present study provides insight into the specific biological behavior of miR-7 in EMT and tumor metastasis. Targeting this novel miR-7/IGF1R/Snail axis would be helpful as a therapeutic approach to block GC metastasis.

Abstract
In order to analyze male sterility caused by deletion of SRY and DAZ, we examined the accuracy and cost-effectiveness of a modified primed in situ labeling (PRINS) technique for detection of single-copy genes. Peripheral blood samples were collected from 50 healthy men; medium-term cultured lymphocytes from these samples were suspended in fixative solution and then spread on clean slides. We used four primers homologous to unique regions of the SRY and DAZ regions of the human Y-chromosome and incorporated reagents to increase polymerase specificity and to enhance the hybridization signal. PRINS of SRY and DAZ gave bands at Yp11.3 and Yq11.2, respectively, in all 50 metaphase spreads. The PRINS SRY signals were as distinct as those obtained using traditional fluorescence in situ hybridization (FISH). This new method is ideal for rapid localization of single-copy genes or small DNA segments, making PRINS a cost-effective alternative to FISH. Further enhancement of PRINS to increase its speed of implementation may lead to its wide use in the field of medical genetics.

Abstract
Systemic lupus erythematosus (SLE) has been considered as stem cell disorder. The objective of this study was to examine the phenotype, growth and immunomodulatory effect of mesenchymal stem cells (MSCs) from SLE patients compared with those from age- and sex-matched healthy donors. MSCs were expanded from bone marrow aspirate and were examined for morphological appearance, quantified in different passages to determine growth rate and evaluated for ability of adipogenesis and osteogenesis. Telomerase activity was measured by telomerase repeat amplification protocol. The immunomodulatory effect of MSCs was evaluated by mixed lymphocyte reaction. MSCs from SLE patients were found to be bigger and flattened in appearance after passage 3 and demonstrated slower growth rate compared with fibroblast-like MSCs from normal controls. These cells were not able to reach confluence after passage 4. Telomerase activity was upregulated in five SLE patients mostly with active disease compared with two with negative expression with lesser activity. MSCs from SLE patients were, otherwise, comparable to normal controls in terms of their surface marker (CD73, CD90 and CD105) expression and extent of suppression on proliferation of allogeneic T lymphocytes. In conclusion, MSCs from SLE demonstrated early signs of senescence which may be a corollary of active lupus or a contributory factor to disease pathogenesis. Lupus (2010) 19, 850-859.
