Abstract
The objective of this study was to evaluate and compare the effectiveness of three different types of bariatric surgeries, namely, sleeve gastrectomy (SG), one-anastomotic gastric bypass (OAGB), and single anastomosis sleeve ileal (SASI) bypass, in the treatment of metabolic syndrome (MS). The optimal approach for managing MS remains uncertain, and thus this study aimed to provide a recent analysis of the efficacy of these surgical procedures. This retrospective study evaluated data of individuals who underwent SG, OAGB, and SASI bypass. The primary outcome measures included weight, body mass index (BMI), glucolipid metabolic index, and the occurrence of treatment-related complications within 6 to 12 months post-surgery. A total of 324 patients were included in this study. Of these, 264 patients underwent SG, 30 underwent OAGB, and 30 underwent SASI bypass. A significant decrease in weight was observed at the 6-month and 12-month marks following all three surgical procedures. Of these, patients who underwent SASI bypass exhibited the greatest reduction in weight and BMI post-surgery. Furthermore, the SASI bypass was associated with a significantly higher percentage of total weight loss (%TWL) and excess body mass index loss (%EBMIL) compared to SG and OAGB. Patients who underwent OAGB and SASI bypass demonstrated notable improvements in type 2 diabetes mellitus (T2DM). Patients who underwent SASI bypass and OAGB experienced greater postoperative comfort and reported fewer complaints of discomfort compared to the other procedure. Based on the retrospective analysis of the data, SASI bypass was associated with greater reductions in weight and BMI, higher percentages of %TWL and %EBMIL, and better improvement in T2DM compared to SG and OAGB. Therefore, both SASI bypass and OAGB were found to be more effective than SG in the treatment of MS.

Abstract
Tetrabromobisphenol A (TBBPA), which is the most widely employed brominated flame retardant, and its alternative tetrachlorobisphenol A (TCBPA) are widely distributed in aquatic environments. In the present study, the hepatotoxicity induced by TBBPA and TCBPA was investigated in Rana nigromaculata, and the potential mechanisms were investigated with a particular focus on ROS (reactive oxygen species) -dependent mitochondria-mediated apoptosis. Healthy adult frogs were exposed to 0, 0.001, 0.01, 0.1, and 1 mg/L waterborne TBBPA and TCBPA for 14 days. The results showed that liver weight was significantly increased by 51.52%-98.99% in the 0.01, 0.1, and 1 mg/L TBBPA and TCBPA groups relative to the control. Histological examination revealed that the structure of the liver, to some extent, was influenced by TBBPA and TCBPA with nuclear shrinkage and mitochondrial swelling. Meanwhile, TBBPA and TCBPA have significantly increased the alanine transaminase level in serum and the content of ROS, while inhibiting the activity of superoxide dismutase in the liver. In addition, DNA fragments were observed in the TBBPA and TCBPA groups relative to the control. Expression of Cytochrome C was significantly increased by 1.13-, 1.38-, 1.60-, and 2.46-fold in 0.001, 0.01, 0.1, and 1 mg/L TBBPA, and by 1.26-, 1.51-, 2.14-, and 2.98- fold in 0.001, 0.01, 0.1, and 1 mg/L TCBPA, respectively, which indicated that TCBPA may be more toxic than TBBPA. Similarly, the ratio of Bax/Bcl-2 was increased in a dose-dependent manner. These results indicated that apoptosis in the ROS-dependent mitochondrial pathway mediates hepatotoxicity caused by TBBPA and TCBPA. The present study will facilitate an understanding of the toxicity mechanism of flame retardants.

Abstract
This prospective study was undertaken to evaluate the treatment outcomes of keratinized mucosa augmentation (KMA) on the buccal and palatal/lingual sides of implants in jaws reconstructed after oncological surgery. Forty-two implants in 12 patients whose jaws had been reconstructed with a fibula or iliac bone flap were included. KMA was performed at 3 months after implant placement; this included an apically displaced partial-thickness flap and a free gingival graft (FGG) around the implants to increase the keratinized mucosa width (KMW). Patients were followed up for at least 6 months post-surgery. KMW, shrinkage, and patient pain and discomfort measured on a visual analogue scale were analysed. A histological analysis was performed of tissue epithelium from two patients. The results showed that KMW was >2 mm on both the buccal and palatal/lingual sides during follow-up. Before surgery, histological analysis showed epithelium with no epithelial spikes; normal keratinized epithelial spikes were observed at 8 weeks after KMA. Greater KMW was observed around implants in reconstructed maxillae than around those in reconstructed mandibles (P < 0.001). Patients felt more pain at the donor site than at the recipient site during the first 3 days post-surgery. KMA with FGG was predictable in reconstructed jaws and may help maintain the long-term stability of implants.

Abstract
Abstract
Study question
The patient sperm has normal morphology and motility, which paternal factors cause the abnormal fertilization in IVF/ICSI and what is the underlying mechanism?
Summary answer
A genetic mutation of BEX1 and decreased PLC-zeta has been found in patient, which may provide novel insights of polyspermy and pronucleus formation during fertilization.
What is known already
In mammals, pronucleus formation, a landmark event for fertilization, is critical for embryonic development. Abnormal fertilization refers to the abnormal number of pronucleus and polar bodies in zygotes during in vitro fertilization, with an incidence of 5–15%, among which the incidence of polyspermy and 0PN is about 2–10% and 30%. However, the mechanisms underlying pronucleus formation still unclear. More research has focused on oocyte activation, while paternal relevant abnormal fertilizations have been rarely established. The mechanism of how sperm and/or substances carried by sperm influence the physiological process of fertilization is also unclear.
Study design, size, duration
In our study, we first work on the preliminary observation and analysis of sperm morphology, structure and sperm chromosome number, and then made further analysis at the genetic level to find out the cause of this particular phenotype in this patient. We use of zone-free golden hamster ova test the fertilizing capacity and rescue the pronucleus formation with SrCl2.
Participants/materials, setting, methods
The patient, golden hamster, Papanicolaou stain, scanning electron microscope (SEM), Transmission Electron Microscope (TEM), Fluorescence in situ hybridization (FISH), Whole Exome Sequencing (WES), IVF, ICSI, Assisted Oocyte Activation (AOA).
Main results and the role of chance
During 2016–2018, they did 4 cycle assistant reproduction technology. Cycle1, conventional IVF(C-IVF), 9 MII oocytes, 9 3PN zygotes; Cycle2, ICSI, 10 MII oocytes, 10 0PN zygotes; Cycle3, donor-oocytes C-IVF, 6 MII oocytes, 6 3PN zygotes, and the donor did C-IVF get normal zygotes and embryos; Cycle4, donor-sperm C-IVF, 7 MII oocytes, 4 2PN zygotes, 3 useable embryos. Remarkably, clinical examination about male shows normal sperm semen parameters. Papanicolaou stain and SEM shows that the sperm of the patient has normal morphology. The TEM data shows that the spermatozoa with normal head morphology and intact 9 + 2 sperm flagella structure. In the sperm FISH analysis, Chromosome ploidy is haploid. We performed WES on the male, after exclusion of frequent variants and application of technical and biological filters, two homozygous missense mutations were identified in BEX1 (c.191G>A [p. W64X]), which has been few reports of male infertility. The western blot result show that the PLC-zeta was decreased in patient. After 10mM SrCl2 assisted oocyte activation, the zygote has the pronucleus formation in ICSI.
Limitations, reasons for caution
At present, we only observe sperm related factors (morphology, structure, chromosome number, genetic mutation). Next step is to detect the substances sperm carried (e.g. RNA-seq, proteomics). In this case, what is of great concern to us is the inconsistencies of the abnormal fertilization during the conventional IVF and ICSI cycles.
Wider implications of the findings: Many studies of fertilization mechanism, the main focus is on the maternal cytoplasmic factors, such as the Ca 2+ release initiate the fast block of oocytes. There are few reports about abnormal fertilization due to sperm factors. Our case may offer new insights for the study of fertilization.

Abstract
The massive use of silver nanoparticles (AgNPs) is potentially harmful to exposed humans. Although previous studies have found that AgNPs can induce cell autophagy, few studies have focused on the toxic pathways and mechanisms of autophagy induced by AgNPs in rat respiratory epithelial (RTE) cells. In this study, RTE cells were exposed to two kinds of AgNPs in vitro to ascertain the influence of mTOR-autophagy pathway-associated protein expression, including Beclin1, LC3B, Atg5, and Atg7. After exposure to different sizes and concentrations of AgNPs for 12 h, the uptake of silver in RTE cells reached 0.45 μg/L to 1.11 μg/L, indicating that AgNPs can enter RTE cells, leading to toxic effects. Our study found that this toxic effect was related to autophagy caused by ROS accumulation that was mediated by the mTOR pathway. With increasing AgNP exposure concentrations, the expression of p-mTOR was significantly downregulated, and expression of the autophagy-related proteins Beclin1, LC3B, Atg5, and Atg7 was significantly increased in RTE cells in all exposed groups. At a concentration of 1000 μg/L, the expression of LC3BII/LC3BI in all exposed groups was 24.49 times and 12.71 times that of the control, and the expression of Atg7 in all exposed groups was 23.21 times and 13.21 times that of the control. The upregulation of autophagy-related proteins in the AgNP-10 nm exposure groups was greater than that of the AgNP-100 nm exposure group. In summary, the mTOR pathway mediates AgNP-induced autophagy in RTE cells, which leads to damage to the respiratory system barrier and human health risks. This study can facilitate the development of prevention and intervention policies against adverse consequences induced by AgNPs.

Abstract
Metal oxide nanoparticles and carbon nanoparticles, as common nanoparticles (NPs), can cause autophagy in certain cells, which will lead to biohealth risk issues. This study determined the difference in autophagy induced by zinc oxide nanoparticles (ZnO NPs) and single-walled carbon nanotubes (SWCNTs) in respiratory epithelial cells. ICP-OES results showed that NPs uptake as well as the intercellular contents of particles affected cytotoxicity in a dose-dependent manner. ZnO NPs-30 nm had a distinct green dot structure representing autophagy, the SWCNTs exposure group had a few green light spots at a concentration of 10 μg/L. The ROS content of the ZnO NP-30 nm exposure group had the greatest increase at a concentration of 1000 μg/L, which was 2.5 times higher than that of the control, the SWCNTs exposure group showed a 2.2-fold increase. A slight downregulation of p-mTOR was detected, and the ZnO NPs-30 nm treatment group had the significant downregulation rate. The gene and protein expression levels of Beclin-1 and LC3B were upregulated as the exposure concentration increased. The protein expression of Beclin-1 and LC3B in the 1000 μg/L ZnO NPs-30 nm exposure group were 5.21 times and 4.12 times that of the control, respectively. The mRNA expression of Beclin-1 and LC3B in the 1000 μg/L ZnO NPs-30 nm exposure group were 5.04 times and 3.61 times that of the control, respectively. At any concentration, the effect of ZnO NPs-30 nm was greater than that of the SWCNTs. Interaction and crosstalk analysis showed that exposure to ZnO NPs-30 nm caused autophagy through the aggregation of undegraded autophagosomes, whereas SWCNTs exposure induced diminished intercellular oxidative stress to inhibit autophagy. Therefore, this study demonstrated that the effects of autophagy induced by ZnO NPs-30 nm and SWCNTs were different. The health risks of ZnO-30 nm NPs are higher than those of SWCNTs.

Abstract
AIM To assess metabolic effects and safety of Roux-en-Y gastric bypass (RYGB) versus conventional medication (CM) in obese Chinese patients with type 2 diabetes (T2DM). METHODS This retrospective cohort study included 40 patients who underwent RYGB (mean age 44.1 years, body mass index [BMI] 33.3 kg/m2 ) and 36 patients administered CM (mean age 49.4 years, BMI 32.1 kg/m2 ). The primary endpoint was achievement of the triple endpoint (haemoglobin A1C [HbA1c] < 7.0%, low-density lipoprotein cholesterol < 2.6 mmol/L, and systolic blood pressure < 130 mmHg). Changes in weight, BMI, medication usage, complications, and adverse events were assessed. RESULTS After 1-year follow-up, 35% of RYGB patients and 8% of CM patients achieved the triple endpoint (P = 0.005). More patients in the RYGB group achieved complete (48% vs 3%, P < 0.001) and partial (23% vs 0%, P = 0.007) remission of diabetes, and complete remission of hypertension (58% vs 24%, P = 0.019). Patients in the RYGB group had greater weight loss and decrease in BMI, waist circumference, fasting and postprandial of blood glucose and insulin levels, HbA1c, blood pressure, triglycerides, and increased high-density cholesterol (P < 0.001- < 0.05). A lower proportion of the RYGB group received antidiabetics, antihypertensives, or antilipemic treatments, and had non-alcoholic fatty liver disease (NAFLD) than the CM group during follow-up. More patients had nutrient deficiency-related diseases in the RYGB group over 1-year follow-up. CONCLUSIONS For obese Chinese patients with T2DM, RYGB resulted in better metabolic control, greater weight loss, and lower medication usage and NAFLD, but more frequently resulted in diseases related to nutrient deficiency.

Abstract
Silver nanoparticles (AgNPs) are increasingly utilized in a number of applications. This study was designed to investigate AgNPs induced cytotoxicity, oxidative stress and apoptosis in rat tracheal epithelial cells (RTE). The RTE cells were treated with 0, 100 μg/L and 10,000 μg/L of the AgNPs with diameters of 10 nm and 100 nm for 12 hr. The cell inhibition level, apoptosis ratio, reactive oxygen species (ROS), malondialdehyde (MDA) and metallothionein (MT) content were determined. The mRNA expression of cytoc, caspase 3, and caspase 9 was measured by quantitative real-time polymerase chain reaction (qRT-PCR). In addition, we also analyzed the cytoc, caspase 3, pro-caspase 3, caspase 9, and pro-caspase 9 protein expression by western blotting. Electric cell-substrate impedance sensing (ECIS) analysis showed that the growth and proliferation of RTE cells were significantly inhibited in a dose-dependent manner under AgNPs exposure. The cell dynamic changes induced by 10 nm AgNPs were more severe than that of the 100 nm AgNPs exposure group. The intracellular MT, ROS, and MDA content increased when the exposure concentration increased and size reduced, whereas Ca2+-ATPase activity and Na+/K+-ATPase activity changed inversely. The relative expression of protein of cytoc, caspase 3, and caspase 9 were upregulated significantly, which indicated that AgNPs induced apoptosis of RTE cells through the caspase-dependent mitochondrial pathway. Our results demonstrate that AgNPs caused obvious cytotoxicity, oxidative stress, and apoptosis in RTE cells, which promoted the releasing of cytochrome C and pro-apoptotic proteins into the cytoplasm to activate the caspase cascade and finally led to apoptosis.

Abstract
Perfluorooctanoic acid (PFOA) is a perfluorinated compound that is widely distributed, is persistent in the environment, and has a low-level chronic exposure effect on human health. The aim of this study was to investigate the peroxisome proliferator activated receptors γ (PPARγ) and the sterol regulatory element-binding protein 2 (SREBP2) signaling pathways in regulating the lipid damage response to PFOA in the livers of amphibians. Male and female frogs (Rana nigromaculata) were exposed to 0, 0.01, 0.1, 0.5 and 1 mg/L PFOA. After treatment, we evaluated the pathological changes in the liver by Oil Red O, staining and examined the total cholesterol (T-CHO) and triglyceride (TG) contents. The mRNA expression levels of PPARγ, Fatty acid synthase (FAS), Acetyl-CoA carboxylase (ACC), Glycerol-3-phosphate acyltransferase (GPAT), SREBP2 and 3-hydroxy-3-methylglutaryl CoA (HMG-CoA) were measured by quantitative real-time polymerase chain reaction (qRT-PCR). The administration of PFOA caused marked lipid accumulation damage in the amphibian livers. The T-CHO contents were elevated significantly after PFOA treatment; these results show a dose-dependent manner in both sexes. The TG content showed a significant increase in male livers, while it was elevated significantly in female livers. The RT-PCR results showed that the mRNA expression levels of PPARγ, ACC, FAS, GPAT, SREBP2 and HMG-CoA were significantly dose-dependently increased in the PFOA-treated groups compared with those of the control group. Our results demonstrated that PFOA-induced lipid accumulation also affected the expression levels of genes FAS, ACC, GPAT and HMG-CoA in the PPARγ and SREBP2 signaling pathways in the liver. These finding will provide a scientific theoretical basis for the protection of Rana nigromaculata against PFOA effects.

Abstract
Perfluorooctanoic acid (PFOA) has been detected in various water bodies and caused harm to aquatic organisms. The aim of this study was to investigate the cytotoxicity and mechanism associated with autophagy and oxidative stress after exposure to PFOA (0, 1, 10, 100 μg/L) for 12 h on lymphocytes, which was isolated from the head kidney of Carassius auratus (C. auratus). Both of autophagy formation, cell activity, and intracellular reactive oxygen species (ROS), malondialdehyde (MDA), glutathione (GSH), and superoxide dismutase (SOD) levels were measured. The relative expression of partial autophagy-related genes autophagy related 5 (Atg 5), autophagy related 7 (Atg 7), and Beclin 1 were also cloned and detected. Homologous relationships analysis showed high identities of genes in C. auratus and other fish by blast. C. auratus lymphocytes growth inhibition rates was increased induced by PFOA. Compared with the control group, the ROS generation and the MDA content were significantly increased in all of the PFOA-treated group. Besides, decreased SOD activity and decrease of GSH activity induced by PFOA further confirmed the occurrence of oxidative stress. The number of autophagosome formations was increased in a dose-dependent manner. Compared with the control group, Atg 7 and Beclin 1 mRNA expression was elevated significantly after PFOA exposed, showing a time-dependent manner, while mRNA expression of Atg 5 was increased remarkably in 100 μg/L PFOA-treated group. Our results indicated that PFOA caused oxidative damage to lymphocytes in C. auratus and caused various autophagy signaling pathway-associated genes imbalances in the lymphocytes. Autophagy signaling pathway-associated genes imbalance could weaken antioxidant capacity and involve in the mechanism of C. auratus lymphocytes oxidative injury caused by PFOA.

Abstract
Tetrabromobisphenol A (TBBPA) and tetrachlorobisphenol A (TCBPA) are persistent toxic environmental pollutants that cause severe reproductive toxicity in animals. The goal of this study was to compare the reproductive toxic effects of TBBPA and TCBPA on male Rana nigromaculata and to expound on the mechanisms leading to these effects. Healthy adult frogs were exposed to 0, 0.001, 0.01, 0.1, and 1 mg/L of TBBPA and TCBPA for 14 days. Sperm numbers were counted by erythrometry. Sperm mobility and deformities were observed under a light microscope (400 × ). We used commercial ELISA kits to determine the serum content of testosterone (T), estradiol (E2), luteinizing hormone (LH) and follicle stimulating hormone (FSH). Expression of androgen receptor (AR) mRNA was detected using real-time qPCR. Sperm numbers and sperm mobility were significantly decreased and sperm deformity was significantly increased in a concentration dependent manner following exposure to TBBPA and TCBPA. Sperm deformity was significantly greater in the 1 mg/L TCBPA (0.549) treatment group than in the 1 mg/L TBBPA (0.397) treatment group. Serum T content was significantly greater in the 0.01, 0.1 and 1 mg/L TBBPA and TCBPA experimental groups compared with controls, while E2 content was significantly greater in only the 1 mg/L TBBPA and TCBPA experimental groups. Expression levels of LH and FSH significantly decreased in the 1 mg/L TBBPA and TCBPA treatment groups. AR mRNA expression decreased markedly in all the treated groups. Our results indicated that TBBPA and TCBPA induced reproductive toxicity in a dose-dependent manner, with TCBPA having greater toxicity than TBBPA. Furthermore, changes in T, E2, LH, and FSH levels induced by TBBPA and TCBPA exposure, which led to endocrine disorders, also caused disturbance of spermatogenesis through abnormal gene expressions of AR in the testes.

Abstract
In the present study, the function of S100 calcium binding protein P (S100P) in the C666-1 nasopharyngeal carcinoma (NPC) cell line was examined. The levels of S100P protein in NPC tissues were analyzed using immunohistochemistry, and small interfering RNA silenced S100P expression in C666-1 cells. Subsequently, cell proliferation, colony formation, migration and wound-healing assays were performed in order to assess whether the knockdown of S100P was able to influence the biological behavior of C666-1 cells. The expression levels of the receptor for advanced glycation end products (RAGE) were analyzed using a western blot following the inhibition of S100P. The immunohistochemistry results revealed that S100P was elevated in expression in 45/78 (57.7%) of patients with NPC, as compared with 5/30 (16.7%) of patients with benign inflammation. The S100P protein levels correlated with the rates of proliferation and migration in C666-1 cells. Additionally, reduced S100P expression levels altered a series of intracellular events, including the downregulation of epidermal growth factor receptor, cluster of differentiation (CD) 44, matrix metalloproteinase (MMP) 2 and MMP9 protein expression. In addition, RAGE expression was downregulated in the S100P silenced C666-1 cells, as detected by western blot analysis. These data suggest that S100P is important during the development and progression of nasopharyngeal cancer. Therefore, S100P may provide a novel treatment target for NPC.

Abstract
The acquisition of an invasive phenotype by epithelial cells occurs through a loss of cellular adhesion and polarity, heralding a multistep process that leads to metastatic dissemination. Since its characterization in 1995, epithelial-mesenchymal transition (EMT) has been closely linked to the metastatic process. As a defining aspect of EMT, loss of cell adhesion through downregulation of E-cadherin is carried out by several transcriptional repressors; key among them the SNAI family of transcription factors. Here we identify for the first time that Lyn kinase functions as a key modulator of SNAI family protein localization and stability through control of the Vav-Rac1-PAK1 (Vav-Rac1-p21-activated kinase) pathway. Accordingly, targeting Lyn in vitro reduces EMT and in vivo reduces metastasis of primary tumors. We also demonstrate the clinical relevance of targeting Lyn as a key player controlling EMT; patient samples across many cancers revealed a strong negative correlation between Lyn and E-cadherin, and high Lyn expression in metastatic tumors as well as metastasis-prone primary tumors. This work reveals a novel pancancer mechanism of Lyn-dependent control of EMT and further underscores the role of this kinase in tumor progression.

Abstract
Bone desensitization after mechanical loading is essential for bone to adapt to its mechanical environment. However, the desensitization mechanism is unknown. Previous studies suggest that G protein-coupled receptors (GPCRs), including P2Y and parathyroid hormone receptors, play important roles in osteoblast mechanobiology. Thus, for the present research, we examined the role of G protein-coupled receptor kinase 2 (GRK2) in osteoblast desensitization after exposure to mechanical stimulation. We first showed the existence of osteoblast desensitization after mechanical stimulation based on cytosol Ca2+ and phosphorylated ERK1/2 activities, detected using a fluorescent Ca2+-sensitive dye and western blotting, respectively. We then demonstrated that GRK2 overexpression in MC3T3-E1 cells inhibits flow-induced ERK1/2 phosphorylation, while siRNA knockdown of GRK2 enhances ERK1/2 phosphorylation. Additionally, we found that GRK2 overexpression in MC3T3-E1 cells inhibits cyclooxygenase-2 mRNA expression in the short term and alkaline phosphatase activity in the long term. More importantly, we discovered that GRK2 translocated to the cell membrane shortly after flow stimulation - a step necessary for GPCR desensitization. Previously, we have demonstrated that P2Y2 purinergic receptors, one type of GPCRs, are involved in various flow-induced osteoblastic responses. In this research, we also showed that GRK2 overexpression does not affect ATP release. Accordingly, GRK2 is able to inhibit flow-induced osteoblast responses possibly through desensitizing P2Y2 receptors.

Abstract
BACKGROUND Healthcare-associated infection (HCAI) represents a major problem for patient safety worldwide. AIM To demonstrate the prevalence, causative agents, and risk factors for HCAI in Chinese hospitals. METHODS A one-day point-prevalence survey was conducted in 52 Chinese hospitals between October 2014 and March 2015. A web-based software system was developed for data entry and management. FINDINGS Among 53,939 patients surveyed, the prevalence of patients with at least one HCAI was 3.7%. Of 2182 HCAI episodes, the most frequently occurring types were lower respiratory tract infections (47.2%), followed by urinary tract infection (12.3%), upper respiratory tract infection (11.0%), and surgical site infection (6.2%). The prevalence of patients with at least one HCAI in critical care units was highest (17.1%). Device-associated infections, including ventilator-associated pneumonia, catheter-associated urinary tract infection, and central catheter-associated bloodstream infection, accounted for only 7.9% of all HCAIs. The most frequently isolated micro-organisms were Pseudomonas aeruginosa [206 infections (9.4%)], Acinetobacter baumannii [172 infections (7.9%)], Klebsiella pneumoniae [160 infections (7.3%)], and Escherichia coli [145 infections (6.6%)]. Of the survey patients (18,206/53,939), 33.8% were receiving at least one antimicrobial agent at the time of the survey. Risk factors for HCAI included older age (≥80 years), male gender, days of hospital admission, admission into a critical care unit, and device utilization. CONCLUSION Our study suggests that the overall prevalence of HCAI in surveyed Chinese hospitals was lower than that reported from most European countries and the USA. More attention should be given to the surveillance and prevention of non-device-associated HCAI in China.

Abstract
Achromatopsia is a progressive autosomal recessive retinal disease characterized by early loss of cone photoreceptors and later rod photoreceptor loss. In most cases, mutations have been identified in CNGA3, CNGB3, GNAT2, PDE6C or PDE6H genes. Owing to this genetic heterogeneity, mutation-independent therapeutic schemes aimed at preventing cone cell death are very attractive treatment strategies. In pde6c(w59) mutant zebrafish, cone photoreceptors expressed high levels of receptor-interacting protein kinase 1 (RIP1) and receptor-interacting protein kinase 3 (RIP3) kinases, key regulators of necroptotic cell death. In contrast, rod photoreceptor cells were alternatively immunopositive for caspase-3 indicating activation of caspase-dependent apoptosis in these cells. Morpholino gene knockdown of rip3 in pde6c(w59) embryos rescued the dying cone photoreceptors by inhibiting the formation of reactive oxygen species and by inhibiting second-order neuron remodelling in the inner retina. In rip3 morphant larvae, visual function was restored in the cones by upregulation of the rod phosphodiesterase genes (pde6a and pde6b), compensating for the lack of cone pde6c suggesting that cones are able to adapt to their local environment. Furthermore, we demonstrated through pharmacological inhibition of RIP1 and RIP3 activity that cone cell death was also delayed. Collectively, these results demonstrate that the underlying mechanism of cone cell death in the pde6c(w59) mutant retina is through necroptosis, whereas rod photoreceptor bystander death occurs through a caspase-dependent mechanism. This suggests that targeting the RIP kinase signalling pathway could be an effective therapeutic intervention in retinal degeneration patients. As bystander cell death is an important feature of many retinal diseases, combinatorial approaches targeting different cell death pathways may evolve as an important general principle in treatment.
