Abstract
Objective: To analyze the status of postpartum weight retention and its associated factors among Chinese lactating women in 2013. Methods: This study was based on the databank of Chinese National Nutrition and Health Surveillance in 2013. Using the multi-stage stratified cluster sampling method, we enrolled 12 514 women, at 0-24 months postpartum, from 55 sites in 30 provinces of China (excluding the Tibet Autonomous Region). Questionnaires were used to collect data on basic characteristics, physical activity, lifestyle, food intake, pre-pregnancy weight, weight before delivery, disease history during pregnancy, delivery date, delivery mode, parity and breastfeeding information. Current body weight and height of each subject were measured. Postpartum weight retention in each subject was calculated as the difference between pre-pregnancy and current weights. High postpartum weight retention was defined as ≥5 kg. Survey sample weights were calculated according to the sampling design and number of children under 2 years old from 2010 population census data of China. Associated factors of high postpartum weight retention were identified by multiple logistic regression analysis. Results: A total of 9 972 women were included in this study. P50 (P25-P75) of weight retention for participants was 3.6 (0.2-7.3) kg and high weight retention accounted for 41.5% of the subjects (4 134/9 972). The weighted means (SE) of weight retention was 3.5 (0.1) kg, and it was at 0 to <3, 3 to <6, 6 to <9, 9 to <12, 12 to <18 and 18 to <24 months postpartum were 5.3 (0.2), 4.5 (0.2), 3.8 (0.2), 3.1 (0.2), 2.8 (0.2) and 3.0 (0.2) kg, respectively. The weighted proportion of high postpartum weight retention was 37.4% (95%CI: 36.0%-38.9%). Compared with women aged under 25 years old, the odds ratio of high postpartum weight retention was 1.31 for women over 30 years old. Compared with women at 18 to <24 months postpartum, the odds ratio of high postpartum weight retention was 2.67, 1.61 and 1.31 for women at 0 to <3, 3 to <6 and 6 to <9 months postpartum, respectively. Compared with women having a pre-pregnant BMI from 18.5 to <25.0 kg/m2, the odds ratio of high postpartum weight retention was 1.30 and 0.67 for women having pre-pregnant BMI <18.5 kg/m2 and ≥25.0 kg/m2, respectively. Compared with women having appropriate gestational weight gain, the odds ratio of high postpartum weight retention was 0.47 and 2.24 for women having low and excessive gestational weight gains, respectively. Compared with farmers, the odds ratio of high postpartum weight retention was 1.44 for housewives. (P<0.05 for all comparisons). Conclusion: Postpartum weight retention in Chinese lactating women is at an intermediate level. High postpartum weight retention is primarily associated with age, postpartum period, pre-pregnant BMI, gestational weight gain and career. The key control factor for weight retention is gestational weight gain, and 1 year postpartum is critical period for weight recovery.

Abstract
We aimed to investigate the biological role of miR-367 in uveal melanoma cell growth and migration, and the underlying mechanism responsible. Quantitative real-time polymerase chain reaction was performed to evaluate miR-367 expression in uveal melanoma tissue samples and cell lines. A miR-367 mimic, miR-367 inhibitor, and negative control oligonucleotide were transfected into these cells to investigate the function of this microRNA. In addition, the role of PTEN in miR-367-mediated uveal melanoma cell growth and migration was evaluated. miR-367 was significantly upregulated in uveal melanoma cells and tissue samples (both P < 0.01). Its inhibition suppressed the proliferation, cell cycle transition, and migration of such cells, and increased levels had the opposite effect. PTEN was confirmed to be a target gene of miR-367. More importantly, co-transfection with a PTEN construct lacking the 3'-untranslated region mitigated miR-367 mimic-induced promotion of uveal melanoma cell proliferation and migration. In summary, miR-367 was found to be upregulated in this malignancy, and may promote uveal melanoma cell proliferation and migration, at least in part by regulating PTEN.

Abstract
PURPOSE To construct a preoperative nomogram to differentiate invasive pulmonary adenocarcinomas (IPAs) from preinvasive lesions in patients with solitary pure ground-glass nodules (GGN). METHODS A primary cohort of patients with pathologically confirmed pulmonary solitary pure GGN after surgery were retrospectively studied at five institutions from January 2009 to September 2015. Half of the patients were randomly selected and assigned to a model-development cohort, and the remaining patients were assigned to a validation cohort. A nomogram predicting the invasive extent of the solitary GGNs was constructed based on the independent risk factors. Predictive performance was evaluated by concordance index (C-index) and calibration curve. RESULTS Out of 898 cases included in the study, 501 (55.8%) were preinvasive lesions and 397 (44.2%) were IPAs. In the univariate analysis, lesion size (p < 0.001), lesion margin (p = 0.041), lesion shape (p < 0.001), mean computed tomography (CT) value (p = 0.018), presence of pleural indentation (p = 0.017), and smoking status (p = 0.014) were significantly associated with invasive extent. In multivariate analysis, lesion size (p < 0.001), lesion margin (p = 0.042), lesion shape (p < 0.001), mean CT value (p = 0.014), presence of pleural indentation (p = 0.026), and smoking status (p = 0.004) remained the predictive factors of invasive extent. A nomogram was developed and validation results showed a C-index of 0.94, demonstrating excellent concordance between predicted and observed results. CONCLUSIONS We established and validated a novel nomogram that can identify IPAs from preinvasive lesions in patients with solitary pure GGN.

Abstract
BACKGROUND Thrombocytopenia is a frequently encountered phenomenon during intra-aortic balloon pumping (IABP), which may limit its prolonged utilization. The aim of the study was to explore the risk factors and clinical implications of IABP-associated thrombocytopenia in patients with acute coronary syndrome (ACS). METHODS We retrospectively analyzed the data of 222 patients with ACS undergoing invasive treatment strategy supported by IABP. The incidence and risk factors of IABP-associated thrombocytopenia, and the association between thrombocytopenia and relevant clinical endpoints (in-hospital death, bleeding according to the TIMI scale, and thromboembolic events), were analyzed. RESULTS IABP-associated thrombocytopenia was observed in 54.5% (121/222) of the patients. The incidence of thrombocytopenia was higher and the magnitude of reduction in platelet count was greater in the Arrow balloon group (n = 89) compared with the Datascope balloon group (n = 133; 68.5% vs. 45.1%, p = 0.001; 48.7% vs. 33.2%, p < 0.001; respectively). Independent predictors of thrombocytopenia included older age and Arrow balloon utilization (odds ratio [OR]: 1.054; 95% confidence interval [CI]: 1.028-1.080; p<0.001; OR: 2.468; 95%CI: 1.375-4.431; p = 0.002; respectively). The incidence of in-hospital death was higher in patients who developed thrombocytopenia than those who did not (9.1% vs. 2.0%, p = 0.041), and thrombocytopenia was correlated with in-hospital death (OR: 5.932; 95%CI: 1.221-28.822; p = 0.027). However, the rates of TIMI bleeding and thromboembolic events were similar between the two groups (5.8% vs. 5.0%, p = 1.000; 3.2% vs. 6.0%, p = 0.518; respectively), and thrombocytopenia was not associated with TIMI bleeding or thromboembolic events (OR: 0.940; 95%CI: 0.267-3.307; p = 0.923; OR: 0.541, 95%CI: 0.148-1.974, p = 0.352; respectively). CONCLUSION IABP-associated thrombocytopenia occurred in 54.5% of patients with ACS undergoing an invasive strategy and it was correlated with increased in-hospital mortality. Older age and use of the Arrow balloon may predict IABP-associated thrombocytopenia.

Abstract
BACKGROUND We investigated the effects of neoadjuvant chemotherapy administered via bronchial arterial infusion (BAI) on unresectable stage III lung squamous cell carcinoma (SCC). METHODS This was a single-arm retrospective study of chemotherapy with gemcitabine plus cisplatin (GP) administered via BAI to patients with unresectable lung SCC. Data regarding the post-treatment response rate, downstage rate, and surgery rate, as well as progression-free survival (PFS), overall survival (OS), quality of life, and post-BAI side effects were collected. RESULTS A total of 36 patients were enrolled in this study between August 2010 and May 2014. The response rate was 72.2%, and the downstage rate was 22.2%. Among the patients who were downstaged, 16 (44.4%) patients were because of their T stage, and 5 (13.9%) patients were downstaged due to to their N stage. The surgery rate was 52.8%, the 1-year survival rate was 75.4%, and the 2-year survival rate was 52.1%. The median PFS was 14.0 months [95% confidence interval (CI): 8.6-19.4], and the median OS was 25.0 months (95% CI: 19.1-30.9). The quality of life was significantly improved, and the chemotherapy was well tolerated. CONCLUSIONS Compared with intravenous neoadjuvant chemotherapy, BAI chemotherapy significantly improved the surgery rate, prolonged PFS and OS, and improved the quality of life in patients with unresectable stage III lung SCC.

Abstract
Objcetive: To investigate the incidence and risk factors of Lymphocele infection and the optimal timing for drainage after pelvic lymphadenectomy. Methods: This retrospective study was carried out on 397 patients who received a pelvic lymphadenectomy with or without a para-aortic lymphadenectomy between January 2009 and April 2016, due to endometrial cancer in General hospital of Tianjin medical university.A total of 76 patients developed lymphocele and 20 patients developed lymphocele infection. Results: (1)The incidence of lymphocele infection was 5.04% (20/397). Single factor analysis indicated diameter of lymphocele ≥5 cm and postoperative anemia were associated with lymphocele formation (P<0.001, P=0.023). Multiple factors Logistic analysis through the adjustment of the factors showed diameter of lymphocele ≥5 cm was the independent risk factors for lymphocyst infection (P<0.001). (2)The total treatment period of cases treated only with antibiotics tended to be shorter than that of cases treated with combined antibiotics and drainage (P=0.008). However, for severe cases which needed drainage, initiating the drainage by day 3 significantly shortened the total treatment period compared with cases started on or after day 4 (P=0.048). Conclusion: To identify the risk factors of the lymphocele infection is useful to help reduce the incidence of them with effective measurement.When drainage is required in addition to antibiotics, the earlier the drainage is performed, the shorter the treatment period is.

Abstract
Tuning the energy of an x-ray probe to an absorption line or edge can provide material-specific measurements that are particularly useful for interfaces. Simulated hard x-ray images above the Fe K-edge are presented to examine ion diffusion across an interface between Fe2O3 and SiO2 aerogel foam materials. The simulations demonstrate the feasibility of such a technique for measurements of density scale lengths near the interface with submicron spatial resolution. A proof-of-principle experiment is designed and performed at the Linac coherent light source facility. Preliminary data show the change of the interface after shock compression and heating with simultaneous fluorescence spectra for temperature determination. The results provide the first demonstration of using x-ray imaging at an absorption edge as a diagnostic to detect ultrafast phenomena for interface physics in high-energy-density systems.

Abstract
We investigate a new laser-driven spherically convergent plasma fusion scheme (SCPF) that can produce thermonuclear neutrons stably and efficiently. In the SCPF scheme, laser beams of nanosecond pulse duration and 10^{14}-10^{15} W/cm^{2} intensity uniformly irradiate the fuel layer lined inside a spherical hohlraum. The fuel layer is ablated and heated to expand inwards. Eventually, the hot fuel plasmas converge, collide, merge, and stagnate at the central region, converting most of their kinetic energy to internal energy, forming a thermonuclear fusion fireball. With the assumptions of steady ablation and adiabatic expansion, we theoretically predict the neutron yield Y_{n} to be related to the laser energy E_{L}, the hohlraum radius R_{h}, and the pulse duration τ through a scaling law of Y_{n}∝(E_{L}/R_{h}^{1.2}τ^{0.2})^{2.5}. We have done experiments at the ShengGuangIII-prototype facility to demonstrate the principle of the SCPF scheme. Some important implications are discussed.

Abstract
Objective: To study the prevalence of delayed onset of lactation (later than 3 days) in lactating women in China and to analyze its influencing factors. Methods: Data were extracted from Chinese National Nutrition and Health Surveillance-Mothers, from mothers with children under 2 years of age (in 2013). A total of 11 178 women who were lactating or had lactated were selected from 55 counties of 30 provinces (excluding the Tibet Autonomous Region) in China, using the multi-stage stratified cluster randomization sampling method. Basic information, including onset of lactation, initiation of breastfeeding, breastfeeding difficulties and breastfeeding knowledge were collected using a questionnaire investigation. The prevalence of delayed onset of lactation were analyzed by the weighted processing of complex sampling from the 6th national population census data. A multiple logistic regression was used to analyze the factors associated with delaged onset of lactation. Results: Among 11 178 lactating women, 3 388 had an onset of lactation later than 3 d. The prevalence of delayed onset of lactation was 30.3%. After complex weighting, the prevalence of delayed onset of lactation was 31.2% (95% CI: 25.7%-36.8%) for lactating women in China. Delivery by Caesarean section (OR=1.28, 95%CI: 1.06-1.53) and initiating breastfeeding ≥4 h (OR= 2.34, 95%CI: 1.76-3.11) were the negative factors for delayed onset of lactation. Compared with those living in large cities, lactating women living in medium or small cities (OR=1.39, 95%CI: 1.05-1.84) had a higher risk of delayed onset of lactation. Compared with the lactating women doing housework, the risk of delayed onset of lactation was lower (P<0.05) among those whose occupations were as leaders of Enterprises/Institutions (OR=0.68, 95%CI: 0.47-0.99), in catering and service trades (OR=0.61, 95%CI: 0.43-0.86), in agriculture/forestry/fishery/herdsmen fields (OR=0.65, 95%CI: 0.44-0.96) and who were unemployed (OR= 0.64, 95%CI: 0.46-0.90). Breastfeeding education during pregnancy might lower the risk of delayed onset of lactation (OR=0.78, 95% CI: 0.62-0.98). Conclusion: The prevalence of delayed onset of lactation was relatively high for Chinese lactating mothers. Caesarean section and late initiation of breastfeeding were the primary risk factors. Lactating mothers living in medium or small cities and those doing housework appear to be high-priority groups for intervention. Based on our findings, breastfeeding education during pregnancy is recommended to lower the risk of delayed onset of lactation.

Abstract
Metal nanoparticles, particularly silver nanoparticles (AgNPs), are developing more important roles as diagnostic and therapeutic agents for cancers with the improvement of eco-friendly synthesis methods. This study demonstrates the biosynthesis, antibacterial activity, and anticancer effects of silver nanoparticles using Dimocarpus Longan Lour. peel aqueous extract. The AgNPs were characterized by UV-vis absorption spectroscopy, X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM), scanning electron microscopy (SEM), and Fourier transform infrared spectroscope (FTIR). The bactericidal properties of the synthesized AgNPs were observed via the agar dilution method and the growth inhibition test. The cytotoxicity effect was explored on human prostate cancer PC-3 cells in vitro by trypan blue assay. The expressions of phosphorylated stat 3, bcl-2, survivin, and caspase-3 were examined by Western blot analysis. The longan peel extract acted as a strong reducing and stabilizing agent during the synthesis. Water-soluble AgNPs of size 9-32 nm was gathered with a face-centered cubic structure. The AgNPs had potent bactericidal activities against gram-positive and gram-negative bacteria with a dose-related effect. AgNPs also showed dose-dependent cytotoxicity against PC-3 cells through a decrease of stat 3, bcl-2, and survivin, as well as an increase in caspase-3. These findings confirm the bactericidal properties and explored a potential anticancer application of AgNPs for prostate cancer therapy. Further research should be focused on the comprehensive study of molecular mechanism and in vivo effects on the prostate cancer.

Abstract
Objective: To investigate the significant role of the clinical application of adult comorbidity evaluation-27 (ACE-27) in endometrial cancer (EC). Methods: A total of 847 EC patients were included during Jan. 1985 to Dec. 2015 from Tianjin Medical University General Hospital. The clinical data of the patients were collected and analyzed retrospectively. All of the patients were received operation with no chemotherapy and radiotherapy before operation. The average age was 57.6 years old (range from 25 to 85 years old). The average follow-up period was 59.0 months (range from 2 to 312 months). The comorbidity of the patients was evaluated by ACE-27. EC patients survival was analyzed by Kaplan-Meier survival curve. The relationship between the prognosis of EC and ACE-27, age, body mass index (BMI) , pathological characteristic were showed by Cox modeling. Results: (1) The patient number of score 0, 1, 2 and 3 of ACE-27 in EC patients were respectively 311 (36.7%), 263 (31.1%), 132 (15.6%) and 141 (16.6%) cases. (2) Kaplan-Meier survival curve analysis showed that overall survival time of EC patients was gradually decreased as increased score of ACE-27 (χ2=19.003, P=0.000) . In the patients of BMI<25 kg/m2 and BMI 25-<30 kg/m2, International Federation of Gynecology and Obstetrics (FIGO) stage Ⅰ, endometrial adenocarcinoma type and the overall survival time of those EC patients were gradually decreased as increased score of ACE-27 (P<0.05) . However, there was no statistically significant difference in overall survival time for patients with BMI ≥30 kg/m2, FIGO stage with Ⅱ-Ⅳand non-endometrial adenocarcinoma type (P>0.05). Per unvariate logistic modeling showed that the risk of death in score 3 of ACE-27 was increased compared with score 0 of ACE-27 (OR=2.53, P=0.000) . The overall survival time in EC patients with aged 50-59, 60-69 and ≥70 years old, BMI 25-<30 kg/m2 and ≥ 30 kg/m2, G3, FIGO stage Ⅱ-Ⅳ and non-endometrial adenocarcinoma type were significantly decreased compared with those aged <50 years old, BMI < 25 kg/m2, G1, FIGO stage Ⅰ and endometrial adenocarcinoma type (all P<0.05) . Further we found that postoperative chemotherapy or radiotherapy rate were decreased for EC patients with FIGO staging Ⅲ or Ⅳ as the increase of ACE-27 score, but there was no statistically significant difference (P>0.05). (3) Per multivariate logistic modeling showed that the risks of death in score 3 of ACE-27 was increased compared with score 0 of ACE-27 among age-adjusted, BMI, histological grade, FIGO stage and pathologic type (OR=2.40, P=0.000) . Per multivariate logistic modeling showed that, the overall survival time in EC patients with aged 60-69 and ≥70 years old, BMI 25-<30 kg/m2 and ≥30 kg/m2, FIGO stage Ⅲ-Ⅳ and non- endometrial adenocarcinoma type remain significantly decreased compared with those aged <50 years old, BMI<25 kg/m2, FIGO stage Ⅰ and endometrial adenocarcinoma type (P<0.05) , but there was no statistically significant difference in histological grade (P>0.05). Conclusions: ACE-27 may become one of the factors of predictive therapy and the prognosis for EC patients. The detailed clinical data of comorbidity should be collected to evaluate prognosis and therapy plan.

Abstract
Objective:To explore the application of laryngeal mask airway in the management of respiratory tract after acute and severe tracheal foreign body removal in children, and to provide a safe and effective treatment for clinical treatment.Method:Seventy cases of children with acute severe tracheal or bronchial foreign body requiring mechanical ventilation transition were randomized to receive, one group was using laryngeal mask airway for airway management after the foreign body was extracted and the bronchoscope was pulled out. Another group was using tracheal intubation. Both groups were received the same general anesthesia induction and maintenance. The blood pressure before induction, before and after insertion of LMA (TT), before and after extubation of LMA(TT) were monitored and recorded. Heart rate, tidal volume,respiratory rate,pulse oxygen saturation, and end-tidal carbon dioxide partial pressure were recorded at the same time in both groups. Airway complications during the recovering between two groups were compared.Result:HR, BP have no significant difference in LMA group before and after implantation LMA (P> 0.05). HR and BP were increased significantly after intubation (P< 0.05) in TT group; Airway pressure, SpO₂ and PET CO₂ exhibited no significant difference between two groups P> 0.05); LMA group has less airway complications than TT group during the recovering.Conclusion:Application of LMA for anesthetic airway management after tracheobronchial foreign body was extracted in children made both less effect on respiratory and circulatory system the regular using tracheal intubation and less damage to the respiratory tract. In addition,the recovery time in LMA group is much shorter than that of TT group.

Abstract
AIM Renal ischaemia-reperfusion injury (IRI) increases angiotensin II (Ang II) and reactive oxygen species (ROS) that are potent modulators of vascular function. However, the roles of individual ROS and their interaction with Ang II are not clear. Here we tested the hypothesis that IRI modulates renal afferent arteriolar responses to Ang II via increasing superoxide (O2-) or hydrogen peroxide (H2 O2 ). METHODS Renal afferent arterioles were isolated and perfused from C57BL/6 mice 24 h after IRI or sham surgery. Responses to Ang II or noradrenaline were assessed by measuring arteriolar diameter. Production of H2 O2 and O2- was assessed in afferent arterioles and renal cortex. Activity of SOD and catalase, and mRNA expressions of Ang II receptors were assessed in pre-glomerular arterioles and renal cortex. RESULTS Afferent arterioles from mice after IRI had a reduced maximal contraction to Ang II (-27±2 vs. -42±1%, P < 0.001), but retained a normal contraction to noradrenaline. Arterioles after IRI had a 38% increase in H2 O2 (P < 0.001) and a 45% decrease in catalase activity (P < 0.01). Contractions were reduced in normal arterioles after incubation with H2 O2 (-22±2 vs. -42±1%, P < 0.05) similar to the effects of IRI. However, the impaired contractions were normalized by incubation with PEG catalase despite a reduced AT1 R expression. CONCLUSIONS Renal IRI in mice selectively impairs afferent arteriolar responses to Ang II because of H2 O2 accumulation that is caused by a reduced catalase activity. This could serve to buffer the effect of Ang II after IRI and may be a protective mechanism.

Abstract
AIM To evaluate the efficacy and safety of ultrasound-guided percutaneous laser ablation (PLA) for recurrent papillary thyroid carcinomas (PTC) <15 mm in the neck. MATERIALS AND METHODS A retrospective study was conducted in 21 patients with 27 recurrent PTC lesions who underwent PLA. The extent of ablation was assessed by contrast-enhanced ultrasonography (CEUS) after PLA. Measurement of the volume of tumour and serum thyroglobulin, and clinical evaluation were performed at 7 days, and 1, 3, 6, and 12 months, and every 6 months thereafter. RESULTS The procedure was well tolerated. Of 21 patients, 18 were successfully treated in a single session. Incomplete ablation was detected by CEUS in three patients, and a second ablation was performed. The mean largest diameter and the average baseline volume were reduced from 7.5±2.8 mm and 105.4±114 mm3 to 0.4±1 mm and 0.8±2.4 mm3 at the final follow-up. CONCLUSIONS Ultrasound-guided PLA is effective for the treatment of recurrent PTCs with a comparable success rate to radio-iodine therapy, and it may become a primary choice of treatment for recurrent PTCs in selected patients who are ineligible for surgery and/or prefer not to have further surgery.

Abstract
Although uniportal video-assisted thoracic surgery (VATS) is becoming more popular, it's still very challenging to conduct a wedge resection of small pulmonary ground-glass opacities (GGOs), especially deeply situated subpleural GGOs, via uniportal VATS. We successfully performed thirteen uniportal VATS wedge resections through an approach that combines radiologically guided microcoil localization with palpation, and we encountered no complications related to the new approach. Based on our experience, a combination of CT-guided microcoil localization with palpation in uniportal VATS for deeply situated subpleural GGOs is a safe and effective procedure for accurate diag¬nosis and resection of indeterminate GGOs.

Abstract
A flexible graphene sensor array has been fabricated by in situ reduction of a graphene oxide (GO) array patterned on a paper chip. To achieve cross-reactive sensing and gas discrimination ability, the surface of each reduced GO (rGO) spot was modified with different types of ionic liquids (ILs), which could significantly alter the semiconductor properties and consequently the gas sensing behaviour of the paper-supported rGO sensor.

Abstract
Several compounds, including the triphenylmethane derivative aurintricarboxylic acid (ATA) and porphyrins, were reported to inhibit the binding of anti-V3 loop-specific antibodies to the V3 loop of gp120 from HIV-1 III-B and to have antiviral activity, probably due to interference with the biological function of the V3 loop. However, these compounds can be applied to antiviral chemotherapy only if they interact with envelope glycoproteins from a multitude of epidemic HIV-1 strains and inhibit their replication. Since recombinant envelope glycoproteins, synthetic peptides and anti-V3 monoclonal antibodies may not be available for these HIV-1 strains, alternative assays are needed to prescreen different compounds for potential antiviral activity against these viruses. Results presented here indicate that: (1) virions of HIV-1 MN, most closely related to primary HIV-1 isolates from European and North American countries, and human anti-HIV-1 antibodies, can also be used for rapid prescreening of antiviral agents, (2) compounds with antiviral activity against HIV-1 MN, discerned by site-directed immunoassays, inhibited the reaction of human anti-HIV-1 with a V3 loop consensus peptide corresponding to European/North American HIV-1 isolates, and (3) meso-tetra (4-carboxyphenyl) porphine (MTCPP), one of the most potent inhibitors of HIV-1 replication selected on the basis of site-directed immunoassays, preferentially attached to the V3 loop of gp120.

Abstract
Recent observations indicated that several porphyrins bound to the V3 loop of the envelope glycoprotein gp120 of the human immunodeficiency virus type 1 (HIV-1) and inhibited infection of cells by HIV-1. The tin derivative of protoporphyrin IX (Sn-PTP-IX) has already been used clinically in humans to suppress hyperbilirubinemia. It was therefore of interest to determine whether Sn-PTP-IX has anti-HIV-1 activity. It is demonstrated here that Sn-PTP-IX effectively inhibited infection by several HIV-1 isolates (HIB, MN, RF, SF-2 and two isolates resistant to azidothymidine). This was surprising, since earlier studies indicated that incorporation of other metals into porphyrins markedly decreased their antiviral activity. Sn-PTP-IX blocked the binding to gp120 of anti-V3-loop-specific antibodies and of monoclonal antibodies specific for the CD4 binding site on gp120. The latter effect appeared to be allosteric and was not observed with a deletion mutant of gp 120 lacking the V3 loop sequence. This suggests that Sn-PTP-IX binds to the V3 loop and distorts the native conformation of the HIV-1 envelope, thereby preventing infection. These results merit the consideration of Sn-PTP-IX as a prophylactic and chemotherapeutic agent against HIV-1.

Abstract
The anionic triphenylmethane derivative aurintricarboxylic acid (ATA) was reported to inhibit the replication and cytopathogenicity of human immunodeficiency virus type 1 (HIV-1). This antiviral effect, ascribed to the inhibitory activity of ATA on the virus reverse transcriptase, was subsequently also explained by binding of ATA to the HIV-1 envelope glycoprotein gp120 and/or to the CD4 receptor for the virus. Results presented here show: (1) the effectiveness of ATA as a potential antiviral drug by demonstrating that HIV-1 replication in vitro can be completely aborted in the presence of ATA as measured by the polymerase chain reaction; (2) that ATA inhibited the reaction between gp120 and antibodies specific for the V3 hypervariable loop of gp120; (3) that additional compounds with anti-HIV-1 activity can be rapidly identified based on their inhibitory effects measured by radioimmunoassays and/or enzyme-linked immunoadsorbent assays; and (4) that ATA also bound to synthetic peptides representing V3 loops of several HIV-1 isolates, suggesting the possibility that selected chemicals would interfere with the biological function of V3 loops of most HIV-1 isolates and would be effective for chemotherapy, and possibly for prophylaxis, of HIV-1 infections.

Abstract
Recent observations that haernin inhibited the replication of the human immunodeficiency virus (HIV-1) and the reaction between the HIV-1 envelope glycoprotein gp120 and antibodies specific for the V3 hypervariable loop of this glycoprotein were an enticement to determine whether or not additional porphyrins had similar activities. Several porphyrin derivatives, particularly meso-tetra (4-carboxyphenyl) porphine, were more potent inhibitors of HIV-1 replication than haernin. They blocked the binding of homologous antibodies to synthetic peptides corresponding to V3 hypervariable loops of 21 distinct HIV-1 isolates, and inhibited the replication in lymphocytic (MT-2) and promonocyte (U937) cell lines of several HIV-1 isolates, tested (IIIB, RF, SF-2, and MN). Compounds with inhibitory activity had a tetrapyrrole ring and, carboxyl or sulphonate groups. However, antiviral activity depended on minor structural difference's between distinct derivatives endowed with these two features. Metalloporphyrins had a drastically reduced antiviral activity in comparison with the corresponding porphyrins. An understanding of the relationship between the structure of porphyrins and their antiviral effects, perceptible from the results presented, is expected to lead to the design of additional derivatives with more potent antiviral activity and to unravelling of molecular details involved in the association between the V3 loop of gp120 and antiviral compounds targeted to this loop.

Abstract
It is anticipated that the rate of sexual transmission of viruses could be substantially decreased by the use of topical chemical barrier methods. Chemical modification of bovine (β-lactoglobulin (β-LG), the major protein of whey, led to the generation of a potent inhibitor (designated 3HP-β-LG) of human immunodeficiency virus type 1 (HIV-1) infection which was also active against herpesviruses. Compounds intended for topical application to prevent sexual transmission of viruses need to maintain their antiviral activity at pH <<7, corresponding to an acidic vaginal environment, and in the presence of seminal fluid. Results presented here show that the binding of 3HP-β-LG to the CD4 receptor for HIV, involved in the anti-HIV-1 activity of this compound, decreases with decreasing pH. The presence of seminal fluid also decreased the binding of 3HP-β-LG to CD4 and diminished the inhibitory effect of the compound on CD4-gp120 binding. 3HP-β-LG was shown to bind Zn++, and the inhibitory effect of seminal fluid could be substantially diminished by chelating Zn++ with ethylenediaminetetraacetate. Saliva had no effect on 3HP-β-LG binding to CD4 or on its interference with gp120-CD4 binding. The decreased 3HP-β-LG-CD4 binding and the concomitant reduction of gp120-CD4 binding inhibition by 3HP-β-LG at low pH and in the presence of seminal fluid could be compensated for by an increase of the 3HP-β-LG concentration and by adding Zn++ chelators to 3HP-β-LG. These results provide a background for the design of 3HP-β-LG formulations for topical use.

Abstract
Modification of the major bovine whey protein, β-lactoglobulin (β-LG) by 3-hydroxyphthalic anhydride (3HP) leads to the generation of a potent inhibitor of infection by human immunodeficiency virus (HIV) types 1 and 2, designated 3HP-β-LG. 3HP-β-LG also has antiviral activity against herpesviruses, albeit at concentrations exceeding those required for inhibition of HIV-1 infection. The topical application of 3HP-β-LG to decrease the rate of sexual transmission of HIV and other sexually transmitted viruses worldwide is being considered. Results presented here: (i) define the conditions for chemical modification of β-LG by 3HP, resulting in 3HP-β-LG with optimum anti-HIV-1 activity; (ii) show that β-LG, prior to chemical modification, or 3HP-β-LG can be exposed to the elevated temperatures used to pasteurize milk without adversely affecting anti-HIV-1 activity; (iii) provide evidence that 3HP-β-LG is a more potent anti-HIV-1 compound than sulphated polysaccharides, other candidate compounds considered as prophylactic agents to prevent sexual transmission of HIV-1; and (iv) confirm that the primary target for 3HP-β-LG is CD4, although binding to the HIV-1 envelope protein gp120 was also observed and contributed to the antiviral activity of 3HP-β-LG.

Abstract
We report on the recently completed 400 TW upgrade to the Scarlet laser at The Ohio State University. Scarlet is a Ti:sapphire-based ultrashort pulse system that delivers >10 J in 30 fs pulses to a 2 μm full width at half-maximum focal spot, resulting in intensities exceeding 5×1021 W/cm2. The laser fires at a repetition rate of once per minute and is equipped with a suite of on-demand and on-shot diagnostics detailed here, allowing for rapid collection of experimental statistics. As part of the upgrade, the entire laser system has been redesigned to facilitate consistent, characterized high intensity data collection at high repetition rates. The design and functionality of the laser and target chambers are described along with initial data from commissioning experimental shots.

Abstract
Despite the impressive clinical efficacy of T cells engineered to express chimeric antigen receptors (CAR-Ts), the current applications of CAR-T cell therapy are limited by major treatment-related toxicity. Thus, safer yet effective alternative approaches must be developed. In this study, we compared CD19 bispecific T-cell engager (BiTE)-transferred T cells that had been transfected by RNA electroporation with CD19 CAR RNA-transferred T cells both in vitro and in an aggressive Nalm6 leukemia mouse model. BiTEs were secreted from the transferred T cells and enabled both the transferred and bystander T cells to specifically recognize CD19+ cell lines, with increased tumor killing ability, prolonged functional persistence, increased cytokine production and potent proliferation compared with the CAR-T cells. More interestingly, in comparison with CD3/CD28 bead-stimulated T cells, T cells that were expanded by a rapid T-cell expansion protocol (REP) showed enhanced anti-tumor activities for both CAR and BiTE RNA-electroporated T cells both in vitro and in a Nalm6 mouse model (P<0.01). Furthermore, the REP T cells with BiTE RNAs showed greater efficacy in the Nalm6 leukemia model compared with REP T cells with CAR RNA (P<0.05) and resulted in complete leukemia remission.

Abstract
The heavy metal cadmium (Cd) is nephrotoxic. Recent studies show that autophagy plays an essential role in Cd-induced kidney injury. However, the mechanisms of Cd-induced kidney injury accompanied by autophagy are still obscure. In the present study, we first confirmed that Cd induced kidney damage and dysfunction, along with autophagy, both in vivo and in vitro. Then, we observed that cyclooxygenase-2 (COX-2) and the eIF2α-ATF4 pathway of endoplasmic reticulum (ER) stress were induced by Cd in both kidney tissues and cultured cells. Further studies showed that inhibition of COX-2 with celecoxib or RNA interference (RNAi) inhibited the Cd-induced autophagy in kidney cells. In addition, blocking ER stress with 4-phenylbutyrate or RNAi partially counteracted COX-2 overexpression and autophagy induced by Cd, which suggested that ER stress was required for Cd-induced kidney autophagy. Significantly, our results showed that Cd activated ATF4 and induced its translocation to the nucleus. Knockdown of ATF4 inhibited Cd-induced COX-2 overexpression. While COX-2 overexpression is involved in renal dysfunction, there is no prior report on the role of COX-2 in autophagy regulation. The results of the current study suggest a novel molecular mechanism that the ER stress eIF2α-ATF4 pathway-mediated COX-2 overexpression contributes to Cd-induced kidney autophagy and injury. The present study implies that COX-2 may be a potential target for therapy against Cd-induced nephrotoxicity.
