Abstract
Objectives: To explore the role of computed tomography (CT) severity index (CTSI) and modified CT severity index (MCTSI) in assessing the severity of acute pancreatitis (AP) under the revised Atlanta classification (RAC) and predicting the clinical prognosis. Methods: Based on the prospectively entered AP database, the clinical data of consecutive adult AP inpatients admitted to the Department of Gastroenterology of the First Affiliated Hospital of Nanchang University from January 2012 to December 2020 were retrospectively screened. The imaging data were independently evaluated by two radiologists and entered to the database to calculate the CTSI and MCTSI scores. Their relationship with the difference of RAC severity grade and clinical prognosis was analyzed. Compared with Acute Physiology and Chronic Health Assessment Ⅱ (APACHE Ⅱ) score, the receiver operating characteristic curve was used to evaluate the predictive value of CTSI and MCTSI scores for persistent organ failure and infectious pancreatic necrosis (IPN). Results: A total of 2 612 patients with AP, aged (50±15) years, were included in the study, including 1 547 males (59.2%) and 1 065 females (40.8%). According to RAC standard, AP was divided into 699 cases (26.8%) of mild pancreatitis (MAP), 1 098 cases (42.0%) of moderately severe pancreatitis (MSAP), and 815 cases (31.2%) of severe pancreatitis (SAP). MCTSI judged AP severity similarly to RAC, with 668 cases of MAP (25.6%), 1 207 cases of MSAP (46.2%) and 737 cases of SAP (28.2%), while CTSI judged SAP patients less(400 cases, 15.3%). The severity of AP determined by CTSI and MCTSI scores was significantly correlated with clinical prognosis (r=0.06-0.43, all P<0.05). Compared with APACHE Ⅱ score, CTSI had the highest area under the curve (AUC) for predicting IPN (AUC=0.85, 95%CI: 0.83-0.87), followed by MCTSI (AUC=0.82, 95%CI: 0.80-0.85). APACHE Ⅱ was more accurate in predicting persistent organ failure than CTSI and MCTSI scores,with AUC of 0.73 (95%CI: 0.71-0.75), 0.72 (95%CI: 0.70-0.74) and 0.72 (95%CI: 0.70-0.74), respectively. Conclusions: AP severity judged by MCTSI is consistent with RAC, and SAP patients judged by CTSI are less than RAC. CTSI and MCTSI are significantly correlated with clinical prognosis. CTSI and MCTSI have higher accuracy in predicting IPN, but lower accuracy in predicting persistent organ failure than APACHE Ⅱ.

Abstract
Parathyroid carcinoma is a rare endocrine malignancy with an increasing rate of incidence. Most parathyroid carcinoma patients will develop local recurrence or metastases leading to poor prognosis. Medical management is the mainstay of treatment for patients with unresectable parathyroid carcinoma. However, the therapeutic outcome of medical management remains unsatisfactory restricted by limited options and efficacy. With the deepening of research, several novel drugs have been reported to be applied in the treatment of parathyroid carcinoma. Calcimimetics and receptor activator for nuclear factor-κB ligand inhibitors aiming to control hypercalcemia have been applied in the endocrine therapy of parathyroid carcinoma. Besides, preliminary studies have shown the therapeutic effects of targeted therapy and immunotherapy on parathyroid carcinoma. These new drugs have shed light on this clinical dilemma; however, their clinical efficacy remains to be determined. In this article, the recent progress in the medical management of parathyroid carcinoma is updated.

Abstract
Objective: To investigate the relationship between nutritional risk status and clinical outcome in children with tuberculous meningitis (TBM). Methods: The clinical data (basic information, clinical symptoms and laboratory test results) of 112 patients with TBM, who were admitted to Department of Pediatric Infectious Diseases of West China Second Hospital of Sichuan University,from January 2013 to December 2020 were retrospectively analyzed. The patients were divided into the nutritional risk group and the non-nutritional risk group according to the assessment of the nutritional risk by the STRONGkids Scale. The variables of basic information, clinical symptoms and laboratory test measurements etc. were compared between the two groups by using Student t test, Rank sum test or Chi-square test. Multivariate Logistic regression analysis were used to analyze nutritional risk factors. Results: Among 112 patient with TBM, 55 were males and 57 females. There were 62 cases in the nutritional risk group and 50 cases in the non-nutritional risk group. The proportion of cases with nutritional risk was 55.4% (62/112). Patients in the nutritional risk who lived in rural areas, had symptoms of brain nerve damage, convulsions, emaciation and anorexia, with a diagnosis time of ≥21 days, and the level of cerebrospinal fluid (CSF) protein were all higher than those in the non-nutritional risk group ((50 cases (80.6%) vs. 32 cases (64.0%), 20 cases (32.3%) vs.8 cases (16.0%), 33 cases (53.2%) vs. 15 cases (30.0%), 30 cases (48.4%) vs. 2 cases (4.0%), 59 cases (95.2%) vs. 1 case (2.0%),41 cases (66.1%) vs.18 cases (36.0%), 1 406 (1 079, 2 068) vs. 929 (683, 1 208) mg/L, χ2=3.91, 3.90, 6.10, 26.72, 98.58, 10.08, Z=4.35, all P<0.05). The levels of serum albumin,hemoglobin,lymphocyte count, white blood cell count, and CSF glucose were significantly lower in patients with nutritional risk ((36±5) vs. (41±4) g/L, (110±17) vs. (122±14) g/L, 1.4 (1.0, 2.0)vs. 2.3 (1.6, 3.8)×109/L, 7.8 (6.3, 10.0)×109 vs. 10.0 (8.3, 12.8)×109/L, 1.0 (0.8, 1.6) vs. 2.1 (1.3, 2.5) mmol/L, t=-6.15, -4.22, Z=-4.86, -3.92, -4.16, all P<0.05).Increased levels of serum albumin (OR=0.812, 95%CI:0.705-0.935, P=0.004) and lymphocyte count (OR=0.609, 95%CI:0.383-0.970, P=0.037) may reduce the nutritional risk of children with TBM; while convulsions (OR=3.853, 95%CI:1.116-13.308, P=0.033) and increased level of CSF protein (OR=1.001,95%CI:1.000-1.002, P=0.015) may increase the nutritional risk of children with TBM. Similarly, the rate of complications and drug-induced liver injury was higher in the nutritional risk group (47 cases (75.8%) vs. 15 cases(30.0%), 31 cases (50.0%) vs.8 cases (16.0%), χ2=23.50, 14.10, all P<0.05). Moreover, the length of hospital stay was also longer in the nutritional risk group ((27±13) vs. (18±7) d, t=4.38, P<0.05). Conclusions: Children with TBM have a high incidence of nutritional risk. Convulsive, the level of serum albumin, the level of lymphocyte count and CSF protein may affect the nutritional risk of children with TBM. The nutritional risk group has a high incidence of complications and heavy economic burden.It is necessary to carry out nutritional screening and nutritional support for children with TBM as early as possible.

Abstract
Abstract
Aim
Glenohumeral joint dislocation is the most common traumatic joint dislocation with a high recurrence rate correlating with age at first dislocation. There is an associated increased incidence in concurrent rotator cuff tears with increasing age affecting 40% aged 40–60. Patient care was assessed against BESS/BOA standard: These patients should have rotator cuff assessment and those aged 40–60 should undergo routine MRI/Ultrasound imaging.
Method
All patients admitted to the emergency departments of the 3 Lanarkshire hospitals undergoing first time traumatic anterior dislocation of the shoulder in February 2021 were included. This was the third cycle of this audit. Previous interventions were presentation at a CPD meeting after cycle one and an NHS Lanarkshire regional meeting after cycle two.
Results
Cycle one (2018)-14 patients. 3/14 underwent rotator cuff assessment. 5/14 aged 40–60. 1/5 underwent rotator cuff imaging.
Cycle two (2020)-11 patients. 0/9 underwent rotator cuff assessment (Two excluded as managed operatively). 4/11 aged 40–60. 0/4 underwent rotator cuff imaging.
Cycle three (2021)-13 patients. 3/11 underwent rotator cuff assessment (Two excluded as managed operatively). 3/13 aged 40–60. 0/3 underwent rotator cuff imaging.
Conclusions
Although a slight improvement has been made over the 3 cycles with rotator cuff assessment the BOA standard is not being met. There has been no improvement in the additional imaging required in traumatic anterior shoulder dislocations in those aged 40–60 over the 3 cycles. These patients may develop pain, reduced function, and rotator cuff arthropathy. There is now an aim to introduce a pathway for these patients across the health board.

Abstract
BACKGROUND Osteosarcoma is the most frequent malignant bone malignancy and the current treatments are ineffective. Ivermectin, an anti-protozoal drug, has been shown to have anti-cancer activity. This work investigated the potential of repurposing ivermectin to augment chemotherapy's efficacy in osteosarcoma. METHODS Proliferation, migration and apoptosis assays were performed in ivermectin-treated osteosarcoma cells. Combination studies were performed. Osteosarcoma xenograft mouse model was established to investigate the in vivo efficacy of ivermectin. Intracellular reactive oxygen species (ROS) and mitochondrial superoxide, membrane potential, ATP, 8-OHdG level, protein carbonylation and lipid peroxidation were determined after ivermectin treatment. RESULTS Ivermectin was effective and acted synergistically with doxorubicin in osteosarcoma cells regardless of cellular origin and genetic profiling. This was achieved through suppressing inhibiting growth and migration, and inducing caspase-dependent apoptosis. Ivermectin also significantly inhibited osteosarcoma growth in vivo and its combination with doxorubicin resulted in much greater efficacy than doxorubicin alone. Importantly, the effective dose of ivermectin was clinically feasible and did not cause significant toxicity in mice. Mechanistical analysis showed that ivermectin induced oxidative stress and damage, and mitochondrial dysfunction. CONCLUSIONS Our findings indicate that ivermectin has utility in treating patients with osteosarcoma, especially those resistant to chemotherapy.

Abstract
BACKGROUND Vulvovaginal candidiasis (VVC) is frequent in women of reproductive age, but very limited data are available on the epidemiology in cases of VVC in China. OBJECTIVES The current study has been conducted to reveal the prevalence, species distribution of yeast causing VVC and molecular genetics of Candida albicans in China. METHODS Vaginal swabs were collected from 543 VVC outpatients recruited in 12 hospitals in China between September 2017 and March 2018. They were preliminarily incubated on Sabouraud dextrose agar and then positive subjects of which were then transmitted to our institute for further identification. CHROMagar™ was used to isolate Candida species, and all isolates were finally identified by DNA sequencing. Multilocus sequence typing (MLST) was used to analyse phylogenetic relationships of the various C. albicans isolates. RESULTS Eleven different yeast species were identified in 543 isolates, among which C. albicans (84.7%) was the most frequent, followed by C. glabrata (8.7%). We obtained 117 unique diploid sequence types from 451 clinical C. albicans isolates and 92 isolates (20.4%) belonged to a New Clade. All the strains appearing in the New Clade were from northern China and they were isolated from non-recurrent VVC. CONCLUSIONS Our findings suggest that C. albicans are still the main cause of VVC in China and the majority of C. albicans isolates belongs to Clade 1 with DST 79 and DST 45 being two most common. Moreover, the New Clade revealed in our study seems to be specific to northern China.

Abstract
Abstract
Introduction
Cauda Equina Syndrome (CES) has a devastating impact on the life of affected individuals. Most patients are reviewed by doctors who do not have specialist spinal expertise. NHS Lanarkshire guidelines for CES are based on ‘Standards of Care in Cauda Equina Syndrome’ (Todd and Dickson) 2016.
Method
Documented assessment of a sample of patients with suspected CES in our hospital was audited against standards set in regional guidelines. A tick-box proforma was introduced to standardise assessment, with re-audit thereafter. Chi-squared was used for statistical analysis.
Results
Cycle 1 (2018): Documented assessment of findings in 30 patients - bilateral radiculopathy (80%), urinary incontinence (93%), faecal incontinence (73%), anal tone (93%), saddle anaesthesia (83%), bladder volumes (90%) and ASIA chart (20%).
Cycle 2 (2019): Documented assessment of above findings was 100% in patients where a proforma was used. Proforma was used in 81% of patients.
Conclusions
Use of a standardised proforma improved assessment of CES. There was a statistically significant improvement in use of an ASIA chart (P < 0.01) and assessment of faecal incontinence (P = 0.039). Compliance with use of this proforma could be improved further, to enhance patient care. Following the success of the proforma, it is being reviewed for implementation on a regional level.

Abstract
OBJECTIVES During the 2019 coronavirus disease (COVID-19) outbreak, malnutrition may contribute to COVID-19 adverse outcomes. We conducted a clinical epidemiological analysis to investigate the association of malnutrition with hospitalized duration in patients with COVID-19. DESIGN Retrospective survey study. SETTING Taikang Tongji (Wuhan) hospital in Wuhan, China. PARTICIPANTS 139 patients with COVID-19. METHODS In total, 139 patients with COVID-19 from patients in the Infection Department of Taikang Tongji (Wuhan) hospital from February 2020 to April 2020 were analyzed retrospectively. We used the "Global leadership Initiative on Malnutrition(GLIM)" assessment standard published in 2019 to assess nutritional status. Prolonged hospitalization was lasting more than the median value of the hospitalized days (17 days) in this population. RESULTS According to the assessment results of GLIM nutrition assessment, the patients were divided into malnutrition group and normal nutrition group. Compared with the patients in the normal nutrition group, the hospitalization time was longer(15.67±6.26 days versus 27.48±5.04 days, P = 0.001). Kaplan-Meier analysis showed patients with malnutrition were more likely to be hospitalized longer compared with those normal nutrition (mean with 95% confidence interval [CI]: 28.91[27.52-30.30] versus 22.78[21.76-23.79], P = 0.001). COX regression analysis showed that malnutrition (hazard ratio [HR] = 3.773, P for trend = 0.001) was proportional associated with being discharged from hospital delayed. CONCLUSION AND IMPLICATIONS Present findings suggested that malnutrition contributed to predicting a probability of prolonged hospitalization in patients with COVID-19 infection, to whom extra attentions and precautions should be paid during clinical treatments. Based on the existing results, it is recommended that inpatients with nutritional risk or malnutrition start nutritional support treatment as soon as possible.

Abstract
PURPOSE Parathyroid carcinoma (PC) is an endocrine malignancy with a poor prognosis. The tumour immune microenvironment is a critical factor influencing the outcomes of multiple cancer types. However, knowledge of the immune microenvironment in PC remains limited. METHODS The intratumoural density of immunocytes and the Ki-67 index were evaluated immunohistochemically in 51 PC patient samples and were compared with clinicopathological features and parafibromin staining results. The Kaplan-Meier method and Cox proportional hazards analysis were used to estimate the effects of these variables on clinical outcomes. RESULTS Intratumoural immunocyte density was not correlated with age, gender, urolithiasis, or palpation of a neck mass. The Ki-67 index was correlated with the intratumoural density of CD3+ cells (P = 0.022) and CD8+ cells (P = 0.021) and serum calcium levels (P = 0.022). In the intratumoural area of primary foci, Kaplan-Meier method showed that the risk factors associated with recurrence/metastasis were a low density of CD3+ (P = 0.017), CD8+ (P = 0.019) and CD45+ cells (P = 0.047), a high density of CD163+ cells (P = 0.003) and a high Ki-67 index (P = 0.004). Cox regression multivariate analysis revealed that CD163+ cell density (hazard ratio (HR) 16.19, 95% confidence interval (CI) 1.99-131.66; P = 0.009) and CD8+ cell density (HR 0.13, 95% CI 0.02-0.76, P = 0.024) were independent factors associated with PC relapse. CONCLUSION The immune microenvironment is an important factor influencing the relapse of PC. The intratumoural density of CD3+, CD8+, CD45+, and CD163+ immunocytes was correlated with disease-free survival (DFS) in patients with PC. Immunotherapy based on T lymphocytes or tumour-associated macrophages may be a promising treatment strategy.

Abstract
Photocatalytic CO2 reforming is considered to be an effective method for clean, low-cost, and environmentally friendly reduction and conversion of CO2 into hydrocarbon fuels by utilizing solar energy. However, the low separation efficiency of charge carriers and deficient reactive sites have severely hampered the efficiency of the photocatalytic CO2 reforming process. Therefore, cocatalysts are usually loaded onto the surface of semiconductor photocatalysts to reduce the recombination of charge carriers and accelerate the rates of surface reactions. Herein, molybdenum (Mo) nanospheres are proposed as a novel non-precious cocatalyst to enhance the photocatalytic CO2 reforming of g-C3N4 significantly. The Mo nanospheres boost the adsorption of CO2 and activate the surface CO2via a photothermal effect. The time-resolved fluorescence decay spectra reveals that the lifetime of photo-induced charge carriers is prolonged by the Mo nanospheres, which guarantees the migration of charge carriers from g-C3N4 to Mo nanospheres. Unexpectedly, Mo loaded g-C3N4 can effectively utilize a wide spectral range from UV to near-infrared region (NIR, up to 800 nm). These findings highlight the potential of Mo nanospheres as a novel cocatalyst for photocatalytic CO2 reforming to CH4.

Abstract
To keep pace with the upcoming big-data era, the development of a device-level neuromorphic system with highly efficient computing paradigms is underway with numerous attempts. Synaptic transistors based on an all-solution processing method have received growing interest as building blocks for neuromorphic computing based on spikes. Here, we propose and experimentally demonstrated the dual operation mode in poly{2,2-(2,5-bis(2-octyldodecyl)-3,6-dioxo-2,3,5,6-tetrahydropyrrolo[3,4-c]pyrrole-1,4-diyl)dithieno[3,2-b]thiophene-5,5-diyl-alt-thiophen-2,5-diyl}(PDPPBTT)/ZnO junction-based synaptic transistor from ambipolar charge-trapping mechanism to analog the spiking interfere with synaptic plasticity. The heterojunction formed by PDPPBTT and ZnO layers serves as the basis for hole-enhancement and electron-enhancement modes of the synaptic transistor. Distinctive synaptic responses of paired-pulse facilitation (PPF) and paired-pulse depression (PPD) were configured to achieve the training/recognition function for digit image patterns at the device-to-system level. The experimental results indicate the potential application of the ambipolar transistor in future neuromorphic intelligent systems.

Abstract
OBJECTIVES Enterovirus 71 (EV71) and coxsackievirus A16 (CA16) were responsible for 43.3% (235 123/543 243) and 24.8% (134 607/543 243) of all laboratory-confirmed hand, foot and mouth disease (HFMD) cases during 2010-2015 in China. Three monovalent EV71 vaccines have been licensed in China while bivalent EV71/CA16 vaccines are under development. A comparative cost-effectiveness analysis of bivalent EV71/CA16 versus monovalent EV71 vaccination would be useful for informing the additional value of bivalent HFMD vaccines in China. METHODS We used a static model parameterized with the national HFMD surveillance data during 2010-2013, virological HFMD surveillance records from all 31 provinces in mainland China during 2010-2013 and caregiver survey data of costs and health quality of life during 2012-2013. We estimated the threshold vaccine cost (TVC), defined as the maximum additional cost that could be paid for a cost-effective bivalent EV71/CA16 vaccine over a monovalent EV71 vaccine, as the outcome. The base case analysis was performed from a societal perspective. Several sensitivity analyses were conducted by varying assumptions governing HFMD risk, costs, discounting and vaccine efficacy. RESULTS In the base case, choosing the bivalent EV71/CA16 over monovalent EV71 vaccination would be cost-effective only if the additional cost of the bivalent EV71/CA16 compared with the monovalent EV71 vaccine is less than €4.7 (95% CI 4.2-5.2). Compared with the TVC in the base case, TVC increased by up to €8.9 if all the test-negative cases were CA16-HFMD; decreased by €1.1 with an annual discount rate of 6% and exclusion of the productivity loss; and increased by €0.14 and €0.3 with every 1% increase in bivalent vaccine efficacy against CA16-HFMD and differential vaccine efficacy against EV71-HFMD, respectively. CONCLUSIONS Bivalent EV71/CA16 vaccines can be cost-effective compared with monovalent EV71 vaccines, if suitably priced. Our study provides further evidence for determining the optimal use of HFMD vaccines in routine paediatric vaccination programme in China.

Abstract
Objective: To analyze the deaths with antiretroviral treatment among adult HIV/AIDS patients in Liangshan Yi Autonomous Prefecture from 2005 to 2015, in order to understand the epidemiological characteristics and to further reduce the mortality rate in Liangshan Prefecture. Methods: The relevant information was collected through the Management Database of Antiretroviral Treatment from the National AIDS Comprehensive Prevention Information System. Results: From 2005 to 2015, a total of 14 219 adult HIV/AIDS patients received antiretroviral treatment and 1 425 death cases were reported during the treatment. The cause of death was mainly AIDS-related diseases (58.9%), and the cumulative mortality rate was 10.02%. Gender, age, the way of infection, duration of antiretroviral therapy, clinical stage when received antiretroviral therapy, and CD(4)(+) T lymphocyte levels were factors for the mortality rate (P<0.001). The mortality increased with older age, higher initiation clinical stage and lower level of CD(4)(+) T lymphocyte. Among the death cases, 82.6% were male, 1 182 (82.9%) were married or cohabited, most aged between 30-39 years old (48.6%). At the initial point of receiving antiretroviral therapy, 49.7% of the cases with CD(4)(+)T lymphocytes levels< 200/μl, 61.2% of the deaths cases were>1 000 copies/ml during the last viral load test, and 16.2% of deaths were ≥500/μl in the last CD(4)(+)T lymphocyte test; 44.5% of deaths were received antiretroviral treatment within one year. Conclusion: Early and timely antiretroviral therapy should be carried out. It is necessary to strengthen the propaganda of antiretroviral therapy and to improve the management quality of follow-up information of antiretroviral therapy case files, and to improve the medication compliance of patients.

Abstract
Objective: Investigate the clinicopathological features for secretory carcinoma of breast (SCB). Methods: The clinical data of 3 SCB cases were collected, immunohistochemical staining was performed by the streptavidin-peroxidase (SP) method to test the expression of the antibodies: ER, PR, HER-2, Ki-67, S100, CK5/6, p63, SMA, calponin, GCDFP-15, and EGFR. Fluorescence in situ hybridization (FISH) was used to detect the ETV6-NTRK3 gene fusion. Results: ER was focal weakly positive in case 1 and case 2 (about 5%) , and negative in case 3. PR was focal weakly positive in case 1 (about 5%) and completely negative in case 2 and case 3. Three cases showed that HER-2, SMA, calponin, GCDFP-15 were negative, while S100, CK5/6, EGFR were diffuse strongly positive. The proliferation index was nearly 15% in case 1 and case 2, and 10% in case 3. p63 was negative in mostly tumor cells of case 1, and focal positive expression in the nucleus and cytoplasm. In case 2, p63 was completely negative. However, p63 was observed positive in the cytoplasm as well as some secretory material in case 3. ETV6-NTRK3 gene fusion detection by FISH was positive in all cases. Conclusions: SCB is a rare low grade triple-negative breast cancer with the unique pathomorphologic features, while its recurrent t (12; 15) (p13; q25) translocation resulting in ETV6 -NTRK3 gene fusion. It has the indolent clinical behavior and good prognosis.

Abstract
Objective: To investigate the epidemiologic and behavioral characteristics of HIV among community population in Liangshan prefecture. Methods: We collected social demographic, behavioral and serological information by means of the monitoring questionnaire and serological tests. Data was analyzed by using the chi-square test and logistic regression. Results: From April to June of 2010 to 2015, 14 092 cases of community population were selected as the study objects, with 267 cases diagnosed as HIV positive patients. The HIV positive rates were 3.24%, 3.07%, 1.17%, 1.38%,1.42% and 1.25%, respectively. We observed that when community population having the following characteristics as: living in Butuo country (OR=3.83), being males (OR=1.77), being Yi nationality (OR=4.40) being widowed (OR=28.57), with history of drug abuse (OR=3.71) or injecting drug use (PWID) (OR=4.92), or history of needle sharing among PWID (OR=8.53), were under higher risks for HIV infection. With histories as: having had secondary or above levels of schooling (OR=0.59), having protected sex with regular partners (OR=0.21) and with non-regular partners (OR=0.46), they seemed to be somehow protected for getting HIV infection. Conclusion: The positive HIV rates of HIV among community population in Dechang, Ningnan and Butuo varied from 0.10% to 8.77% while the HIV transmission among general population remained challenging.

Abstract
The radiochromic film (RCF) is a high-dose, high-dynamic range dosimetry detection medium. A stack of RCFs can be used to detect both spatial and energetic distribution of laser driven ion beams with a large divergence angle and continuous energy spectrum. Two types of RCFs (HD-V2 and MD-V3, from Radiation Products Design, Inc.) have been calibrated using MeV energy protons and carbon ions produced by using a 2 × 6 MV tandem electrostatic accelerator. The proportional relationship is obtained between the optical density and the irradiation dose. For protons, the responses are consistent at all energies with a variation of about 15%. For carbon ions, the responses are energy related, which should be noted for heavy ion detection. Based on the calibration, the broad energy spectrum and charge distribution of laser accelerated proton beam with energy from 3 to 8 MeV and pC charge were detected and reconstructed at the Compact LAser Plasma Accelerator at Peking University.

Abstract
We report the experimental generation of highly energetic carbon ions up to 48 MeV per nucleon by shooting double-layer targets composed of well-controlled slightly underdense plasma and ultrathin foils with ultraintense femtosecond laser pulses. Particle-in-cell simulations reveal that carbon ions are ejected from the ultrathin foils due to radiation pressure and then accelerated in an enhanced sheath field established by the superponderomotive electron flow. Such a cascaded acceleration is especially suited for heavy ion acceleration with femtosecond laser pulses. The breakthrough of heavy ion energy up to many tens of MeV/u at a high repetition rate would be able to trigger significant advances in nuclear physics, high energy density physics, and medical physics.

Abstract
Due to the sluggish mobility of holes, the low charge-separation rate remains an intrinsic issue that limits further increase of the photocatalytic conversion efficiency. Herein, we proposed an in situ hydrothermal method to expedite the charge transfer with enhanced photocatalytic H2 evolution rate and photodegradation activities via introducing SnO microplates into TiO2. As compared to bare TiO2, the SnO/TiO2 heterojunction achieves remarkable 470% and 150% higher efficiency for the photocatalytic H2 evolution rate and photodegradation of rhodamine B, respectively. In particular, it is demonstrated that the charge transfer mechanism of SnO/TiO2 can be switched from the Z-scheme to type II by Pt loading, leading to a significant enhancement of photocatalytic performances. Furthermore, the photocatalytic H2 evolution activities of ZnO and C3N4 can also be improved by introducing SnO via simple mechanical mixing. This work provides not only a new versatile stimulant for enhancing photocatalytic activities but also in-depth understanding of the charge transfer mechanism of heterointerfaces of semiconductors.

Abstract
This study was carried out to determine the incidence of hepatitis B virus (HBV) infection in the young generation born after mandatory implementation of hepatitis B vaccination since 1992. Repeat blood donors born between 1992 and 1997 were enrolled, who gave blood at least twice during the past 3 years. Donors were tested for HBV infection markers of HBsAg, anti-HBc, anti-HBs and viral DNA by immunoassays (EIAs) and nucleic acid tests (NAT). A total of 14 937 pre-donation screening qualified young repeat donors aged 18-23 years were tested with 9 (0.06%) being HBsAg by EIA and 10 (1:1494) HBV DNA positive by Ultrio NAT (10.4 IU/mL), respectively. HBV DNA was further detected in 1:192 (9/1732) anti-HBc+ repeat donors with Ultrio Plus NAT (3.4 IU/mL). Most cases were identified as occult HBV infection (OBI). Of 14 937 repeat donors, 20.9% were anti-HBc+ positive, while approximately 50% of 12 024 repeat donors were anti-HBs negative or had levels <100 IU/L. HBsAg+ or OBI strains were classified as wild type of genotype B or genotype C. Incident HBV infection in repeat donors was approximately 1:18.5 person-years (1.1%/year) but significantly less frequent in donors with confirmed HBV vaccination (2.4%-3.3%) than those unsure of vaccination status (10.5%; P = .0023). Hepatitis B virus vaccination appears largely protective of HBV infection, but incidence of infections increases in young adults with mostly undetectable or low anti-HBs or occasionally high anti-HBs. A boost of hepatitis B vaccine for adolescents prior to age 18 years may reduce HBV infection, and implementation of more sensitive NAT in blood donation screening may improve HBV safety in blood transfusion.

Abstract
Phototunable biomaterial-based resistive memory devices and understanding of their underlying switching mechanisms may pave a way toward new paradigm of smart and green electronics. Here, resistive switching behavior of photonic biomemory based on a novel structure of metal anode/carbon dots (CDs)-silk protein/indium tin oxide is systematically investigated, with Al, Au, and Ag anodes as case studies. The charge trapping/detrapping and metal filaments formation/rupture are observed by in situ Kelvin probe force microscopy investigations and scanning electron microscopy and energy-dispersive spectroscopy microanalysis, which demonstrates that the resistive switching behavior of Al, Au anode-based device are related to the space-charge-limited-conduction, while electrochemical metallization is the main mechanism for resistive transitions of Ag anode-based devices. Incorporation of CDs with light-adjustable charge trapping capacity is found to be responsible for phototunable resistive switching properties of CDs-based resistive random access memory by performing the ultraviolet light illumination studies on as-fabricated devices. The synergistic effect of photovoltaics and photogating can effectively enhance the internal electrical field to reduce the switching voltage. This demonstration provides a practical route for next-generation biocompatible electronics.

Abstract
The in-depth understanding of ions' generation and movement inside all-inorganic perovskite quantum dots (CsPbBr3 QDs), which may lead to a paradigm to break through the conventional von Neumann bottleneck, is strictly limited. Here, it is shown that formation and annihilation of metal conductive filaments and Br- ion vacancy filaments driven by an external electric field and light irradiation can lead to pronounced resistive-switching effects. Verified by field-emission scanning electron microscopy as well as energy-dispersive X-ray spectroscopy analysis, the resistive switching behavior of CsPbBr3 QD-based photonic resistive random-access memory (RRAM) is initiated by the electrochemical metallization and valance change. By coupling CsPbBr3 QD-based RRAM with a p-channel transistor, the novel application of an RRAM-gate field-effect transistor presenting analogous functions of flash memory is further demonstrated. These results may accelerate the technological deployment of all-inorganic perovskite QD-based photonic resistive memory for successful logic application.

Abstract
Inspired by the highly parallel processing power and low energy consumption of the biological nervous system, the development of a neuromorphic computing paradigm to mimic brain-like behaviors with electronic components based artificial synapses may play key roles to eliminate the von Neumann bottleneck. Random resistive access memory (RRAM) is suitable for artificial synapse due to its tunable bidirectional switching behavior. In this work, a biological spiking synapse is developed with solution processed Au@Ag core-shell nanoparticle (NP)-based RRAM. The device shows highly controllable bistable resistive switching behavior due to the favorable Ag ions migration and filament formation in the composite film, and the good charge trapping and transport property of Au@Ag NPs. Moreover, comprehensive synaptic functions of biosynapse including paired-pulse depression, paired-pulse facilitation, post-tetanic potentiation, spike-time-dependent plasticity, and the transformation from short-term plasticity to long-term plasticity are emulated. This work demonstrates that the solution processed bimetal core-shell nanoparticle-based biological spiking synapse provides great potential for the further creation of a neuromorphic computing system.

Abstract
Colorectal cancer (CRC), one of the common malignant cancers in the world, is caused by accumulated alterations of genetic and epigenetic factors over a long period of time. Along with that protein-coding genes being identified as oncogenes or tumor suppressors in CRC, a number of lncRNAs have also been found to be associated with CRC. Considering the important regulatory role of lncRNAs, the first goal of this study was to identify CRC-associated lncRNAs from a public database. One such lncRNA, LINC00472, was verified to be downregulated in CRC cell lines and cancer tissues compared with adjacent tissues. In addition, the down-regulation of LINC00472 seemed to be caused by DNA hypermethylation at its promoter region. Furthermore, the expression of LINC00472 and DNA methylation of promoter were significantly correlated with clinicopathological features. And DNA hypermethylation of LINC00472 may serve as a better diagnostic biomarker than its expression for CRC. Finally, we predicted the functions of LINC00472 and constructed a regulatory network and found LINC00472 may be involved in cell cycle and cell proliferation processes. Our results may provide a clue to further research into the function and regulatory mechanism of LINC00472 in CRC.

Abstract
Nonspecific digestive disorders (NSDD) are one of the major intestinal problems in rabbit, with considerable economic losses in industrial rabbit farms. MicroRNAs (miRNAs), as small non-coding RNAs, have significant biological involvement in intestinal disorders. In this study, we investigated the expression levels of 25 genes and 25 miRNAs in ileum, rabbit sacculus rotundus (RSR) and colon tissues from 9 rabbits with different severity of NSDD. These molecules have been found to be related to NSDD or inflammatory bowel disease, which will help recognise the miRNA-mRNA pairs. Finally, 108 possible pairs of miRNA-mRNA pairs with an anti-correlation were identified by Pearson’s correlation analysis between differentially expressed 25 miRNAs and 23 mRNAs. Ninety-five of these miRNA-mRNA pairs were hitherto unexplored, and their roles in NSDD biology require further elucidation. Our results give a clue to the potential miRNA-mRNA pairs for the NSDD that can further improve the understanding of the pathogenesis of NSDD in rabbit.

Abstract
The aim of this study was to assess the importance of p16 gene expressions in pancreatic cancer tissue for early diagnosis and treatment. Two groups were included in the study: an experimental group of 35 pancreatic cancer tissue specimens and a control group of 35 pancreatic cancer adjacent tissues collected during surgery. The expression of p16 gene in the two groups was observed using the immunohistochemical streptavidin peroxidase conjugated (S-P) method. The results were statistically interpreted using SPSS22.0 software. The positive expression rate of p16 in the experimental group was lower than that of the control group (p less than 0.05). Comparing the intensity of p16 gene expression, differentiation degree, clinical stage and metastases of nearby lymph nodes the differences had statistical significance (p less than 0.05). The intensity of p16 gene expression in high and medium differentiated pancreatic cancer group was higher than that of the low differentiated group. p16 gene expression in stages III and IV groups was lower than that in stages I and II groups. Differentiation degree, clinical stage, metastases of nearby lymph nodes and distant metastasss were negatively related with p16 gene expression (p less than 0.05). There was no correlation between age or gender and p16 gene expression. The decreased expression of p16 gene in pancreatic cancer tissue was negatively correlated with differentiation degree and clinical stage. Our results indicated that p16 can be used as a cue signal for diagnosing advanced pancreatic cancer.

Abstract
Understanding the biology of spontaneous clearance of hepatitis C virus (HCV) infection could lead to improved strategies to prevent the sequelae associated with chronic HCV infection. Chronic infections with hepatitis virus are very common in China, but the factors associated with spontaneous clearance of HCV have not been adequately studied. We evaluated the spontaneous clearance of HCV among 1918 drug users and 1526 HCV-seropositive blood donors in Guangzhou, China. Among participants who were co-infected with hepatitis B virus (HBV), 41.38% of drug users and 39.47% of blood donors had cleared their HCV infection without antiviral therapy compared to 9.41% of drug users and 16.73% of blood donors who were mono-infected with a single virus (P<.01). The proportion of subjects who had cleared their HCV infection was significantly greater in the co-infected subjects whose serum HBV DNA was greater than 2000IU/mL than those with lower levels. A multiple logistic regression analysis found female gender, IL28B rs8099917 TT genotype, HBV co-infection and blood donors (vs drug users) associated with increased spontaneous clearance of HCV infection. Although acute HCV infections are common in China, the incidence of chronic HCV may be reduced among the high prevalence of chronic HBV and IL28B genotypes associated with spontaneous clearance of HCV in Chinese populations.

Abstract
Objective: To explore the clinical characteristics of drug-resistant tuberculosis (TB) in children and to study the effectiveness of second-line anti-TB therapy for children and to examine the incidence of adverse drug reactions. Method: Retrospective research was conducted. The clinical records of children in West China Second Hospital diagnosed as drug-resistant TB from January 2010 to June 2014 were investigated.The clinical characteristics and risk factors were analyzed retrospectively. Treatment effect at discharge was examined as a short-term outcome indicator to evaluate the effectiveness of second-line anti-TB therapy and the incidence of adverse drug reactions. χ(2) test was used. Result: Forty-six patients were diagnosed as drug-resistant TB in 443 children infected with TB, with a 10.4% resistance rate. The 46 children included 26 male and 20 female patients, aged from one month and 28 days to 17 years and 5 months, with the average age (8.4±4.5) years, >7 to 14 years old patients as the biggest part(25 patients, 54.3%). Among the 46 children, 20 patients(43.5%)had close contact with TB patients, of whom 12 patients (60.0%) contacted with family members (including parents, brothers and sisters and grandparents living together) and 8 patients(40.0%) contacted with patients from outside family (such as relatives or neighbors). Moreover, 11 cases (23.9%) were under initial treatment and 35 cases (76.1%) were retreated.From 2010 to 2014, the number of cases of initial and retreated patients had no significant difference(0 and 1, 1 and 13, 4 and 7, 4 and 11, 2 and 3 cases, χ(2)=3.255, P=0.196). Among retreated patients, 31.4% (11/35) had irregular treatment before.Until discharge, the effective rate was 87.0% (40/46), while the incidence rate of adverse drug reaction was 10.9%(5/46). Conclusion: The therapy for drug-resistant TB is effective and the incidence of adverse drug reaction is relatively low.

Abstract
OBJECTIVE This paper aimed to analyze the situation of HIV infection in Liangshan Yi Autonomous, including HIV recent rate of infection and the ongoing strategies on prevention of the disease in this prefecture. METHODS Surveillance data on population size, medical institutions, from 2011 to 2013 in Liangshan prefecture was collected. The total numbers of people living in the areas appeared as 412 608, 393 699 and 443 025 from the above mentioned three years. The overall numbers of people living with HIV/AIDS were 4 480, 3 999 and 4 719 respectively in the three years of observation, using the ELISA and WB blot. We also used the ELISA, and Western blotting methods to find out the HIV-positive individuals. We then applied the ' BED HIV-1 incidence capture enzyme immunoassay (BED-CEIA)' on these HIV-positive individuals to locate those who were recently infected, to estimate the annual recent infection rates. RESULTS The HIV-positive rates in Liangshan Prefecture appeared as 1.09%, 1.02% and 1.07% respectively, from 2011 to 2013, with the recent infection rates as 0.34% (95%CI: 0.32-0.37), 0.62% (95%CI: 0.58-0.66) and 0.61% (95%CI: 0.57-0.65) respectively. The newly infections mainly involved with males, with Yi ethnicity, married, being illiterate or received primary school education. In males, the rates of infection appeared as 64.24% (433/674), 59.22% (504/851) and 58.37% (495/848) respectively, in the three years of observation among people with Yi ethnicity, the recent infection rates were 84.72% (571/674) in 2011, 94.59% (805/851) in 2012 and 84.20% (714/848) in 2013. The rates seen in married people were 61.57% (415/674), 61.45% (523/851) and 60.50% (513/848) respectively. Among the illiterates or people only received primary school education, the rates appeared as 60.24% (406/674) in 2011, 61.57% (524/851) in 2012, and 60.03% (509/848) in 2013. CONCLUSION Using the HIV recent infection rate to describe the situation of AIDS in Liangshan prefecture, figures seemed to be more reliable than under the regular HIV-positive rate.

Abstract
Abstract
Background
Laparoscopic spleen-preserving distal pancreatectomy (LSPDP) is designed principally for the removal of benign and low-grade malignant lesions in the left pancreas. The aims of this study were to compare LSPDP with laparoscopic distal pancreatectomy with splenectomy (LDPS), compare two splenic preservation techniques (splenic vessel preservation and Warshaw technique) and investigate factors that influence splenic preservation.
Methods
Information from patients who underwent laparoscopic distal pancreatectomy between December 2004 and January 2016 at a single institution was reviewed. Data were extracted from a prospectively developed database. Intention-to-treat and propensity score matching analyses were employed. Univariable and multivariable analyses were used to investigate factors affecting splenic preservation.
Results
There were 206 patients in total (126 planned LSPDP and 80 planned LDPS procedures), of whom 108 underwent LSPDP and 98 LDPS. In intention-to-treat analysis, the duration of surgery was significantly shorter in the LSPDP group than in the LDPS group (mean 191·0 versus 220·5 min respectively; P < 0·001). Tumour size was an independent risk factor for splenic vessel resection in planned splenic vessel preservation operations, and a cut-off value of 3 cm provided optimal diagnostic accuracy. After a median follow-up of 35·9 months, there were no clinically significant splenic infarctions and no patient developed gastrointestinal bleeding after LSPDP.
Conclusion
Planned LSPDP had a high splenic preservation rate and was associated with significantly shorter operating time than LDPS. Splenic vessel preservation could be predicted using a tumour cut-off size of 3 cm.

Abstract
BACKGROUND Enucleation of pancreatic neuroendocrine tumours (pNETs) via robotic surgery has rarely been described. This study sought to assess the safety and efficiency of robotic surgery for the enucleation of small pNETs. METHODS A comparison was conducted of enucleation of pNETs smaller than 2 cm by robotic or open surgery between January 2000 and May 2015. Propensity score matching was used to balance sex, age, BMI, tumour location and tumour diameter. Pathological results, safety-related outcomes (postoperative pancreatic fistula (POPF) rate, estimated blood loss, and short-term mortality and morbidity) and efficiency-related outcomes (duration of surgery and postoperative length of hospital stay) were compared between the groups. RESULTS A cohort of 120 patients with pNET were enrolled in the study (1 : 1 matched for open or robotic surgery, 60 per group). Ninety-three patients (77·5 per cent) had a grade 1 tumour and 114 (95·0 per cent) had an insulinoma. Robotic surgery had a conversion rate of 5 per cent (3 of 60), and was not associated with an increased POPF rate (10 per cent versus 17 per cent after open surgery; P = 0·283) or grade III-V surgical complications according to the Dindo-Clavien classification (3 versus 10 per cent respectively; P = 0·272). Estimated blood loss was reduced with the robotic approach (32·5 versus 80·0 ml in the open group; P = 0·008), as was duration of surgery (117 versus 150 min; P < 0·001). Length of hospital stay after surgery was similar in the two groups (12·0 versus 13·5 days respectively; P = 0·071). CONCLUSION Robotic surgery for enucleation of pNETs smaller than 2 cm did not increase POPF or major complication rates, and reduced the duration of surgery and estimated blood loss, compared with open surgery.

Abstract
Passenger leukocyte transfer from the donor lung to the recipient is intrinsically involved in acute rejection. Direct presentation of alloantigen expressed on donor leukocytes is recognized by recipient T cells, promoting acute cellular rejection. We utilized ex vivo lung perfusion (EVLP) to study passenger leukocyte migration from donor lungs into the recipient and to evaluate the effects of donor leukocyte depletion prior to transplantation. For this purpose, female pigs received male left lungs either following 3 h of EVLP or retrieved using standard protocols. Recipients were monitored for 24 h and sequential samples were collected. EVLP-reduced donor leukocyte transfer into the recipient and migration to recipient lymph nodes was markedly reduced. Recipient T cell infiltration of the donor lung was significantly diminished via EVLP. Donor leukocyte removal during EVLP reduces direct allorecognition and T cell priming, diminishing recipient T cell infiltration, the hallmark of acute rejection.

Abstract
BACKGROUND Currently 80% of donor lungs are not accepted for transplantation, often due to fluid overload. Our aim was to investigate if forced fluid infusion may be replaced by a new pharmacological therapy to stabilize circulation after brain death in an animal model, and to assess therapy effects on lung function and morphology trough blood gas parameters and state-of-the-art High-resolution CT (HRCT). METHODS Brain death was caused by surgical decapitation. To maintain mean aortic pressure > 60 mmHg, pigs were treated with forced electrolyte solution infusion (GI; n = 6) or the pharmacological therapy (GII; n = 11). GIII (n = 11) were non-decapitated controls. Lung function was investigated with blood gases and lung morphology with HRCT. RESULTS GI pigs became circulatory instable 4-6 h after brain death in spite of forced fluid infusion, five pigs showed moderate to severe pulmonary edema on HRCT and median final PaO2 /FiO2 was 29 kPa (Q1; Q3; range 26; 40; 17-76). GII and GIII were circulatory stable (mean aortic pressure > 80 mmHg) and median final PaO2 /FiO2 after 24 h was 72 kPa (Q1; Q3; range 64; 76; 53-91) (GII) and 66 kPa (55; 78; 43-90) (GIII). On HRCT, only two pigs in GII had mild pulmonary edema and none in GIII. More than 50% of HRCT exams revealed unexpected lung disease even in spite of PaO2 /FiO2 > 40 kPa. CONCLUSION Pharmacological therapy but not forced fluid infusion prevented circulatory collapse and extensive HRCT verified pulmonary edema after acute brain death. HRCT was useful to evaluate lung morphology and revealed substantial occult parenchymal changes justifying efforts toward a more intense use of HRCT in the pre-transplant evaluation.

Abstract
BACKGROUND Genetic variability of methylenetetrahydrofolate reductase (MTHFR) may be associated with Parkinson's disease (PD). Its role in ethnic Chinese population is still unclear. Our study aimed to investigate whether MTHFR C677T variation was linked to PD risk in a Han Chinese population from mainland China. METHODS To investigate the association with the risk of PD, we analyzed the single-nucleotide polymorphism C677T in MTHFR gene using a case-control methodology. A total of 1482 subjects included 765 patients with idiopathic PD, and 717 age- and sex-matched controls were recruited in this study. RESULTS The T allele of MTHFR C677T was associated with a decreased risk of PD (OR = 0.80, 95% CI: 0.688-0.926, P = 0.003). Patients with CT + TT genotypes have a decreased risk of PD compared with those with CC genotypes (OR = 0.66, 95%CI: 0.532-0.813, P = 0.000). CT + TT subjects cannot be differentiated from CC subjects based on their clinical features. CONCLUSION We showed that the C677T polymorphism in MTHFR gene was associated with decreased PD susceptibility in a Han Chinese population from mainland China. Efforts to fully elucidate the pathophysiologic role of the variant in PD should be necessary.

Abstract
Bacterial vaginosis frequently persists, even after treatment. The role of some strains of bacteria associated with bacterial vaginosis treatment failure remains poorly defined. The aim of our study was to define the risk of bacterial vaginosis treatment failure, including pre-treatment detection of specific vaginal bacteria. Bacterial vaginosis is present when the Nugent score is ≥7 and the modified Amsel criteria is positive. Women with bacterial vaginosis were treated with intravaginal metronidazole gel nightly for 5 nights. The 454 pyrosequencing method was used to detect bacteria in vaginal fluid. By univariate analysis, a history of bacterial vaginosis, intrauterine device use and the presence of Facklamia, Corynebacterium and Veillonella were significantly associated with bacterial vaginosis treatment failure. Lactobacillus crispatus, Lactobacillus pentosus and Megasphaera were significantly associated with curing bacterial vaginosis. After logistic regression analysis and detection of these bacteria for test-of-cure, we found that women who had a history of bacterial vaginosis had a higher incidence of bacterial vaginosis treatment failure, whereas women with L. crispatus had a lower incidence of treatment failure. Post-treatment sexual activity was not associated with the treatment effect. Our data suggested that treatment failure may be not caused by drug resistance. Rather, it has a closer relationship with the failed restoration of lactobacilli.

Abstract
We compute spectrograms and relative time delays for laser-assisted photoemission by single attosecond extreme ultraviolet pulses from valence band (VB) and 2p core levels (CLs) of a Mg(0001) surface within a quantum-mechanical model. Comparing the time-dependent dispersion of photoelectron (PE) wave packets for VB and CL emission, we find striking differences in their dependence on the (i) electron mean free path (MFP) in the solid, (ii) screening of the streaking laser field, and (iii) chirp of the attosecond pulse. The relative photoemission delay between VB and 2p PEs is shown to be sensitive to the electron MFP and screening of the streaking laser field inside the solid. Our model is able to reproduce a recent attosecond-streaking experiment [S. Neppl et al., Phys. Rev. Lett. 109, 087401 (2012)], which reveals no relative streaking time delay between VB and 2p PEs.

Abstract
BACKGROUND Glaucoma is a neurodegenerative disease which is the second most common cause of blindness worldwide. AIM To investigate the mechanism of glaucoma and identify small molecule drugs. MATERIALS AND METHODS Gene expression profiles of GSE2378 were downloaded from Gene Expression Omnibus (GEO) database which included 15 astrocytes from 8 and 7 donors with and without glaucoma, respectively. Then the raw data were normalized by Robust Multichip Averaging and the differentially expressed genes (DEGs) were identified with limma package in R. Moreover, the Gene Ontology and pathway enrichment analyses were performed by GOEAST and Gene Set Analysis Toolkit V2, respectively. In addition, the potential target sites of transcription factors were detected using MSigDB. Finally, small molecule drugs were screened for glaucoma treatment by Connectivity Map. RESULTS A total of 961 DEGs between glaucoma and normal cells were identified. These DEGs were discovered mainly involved in cell surface, molecule binding, changes in protein activity and signal transduction. Additionally, the most significant pathway was pathway in cancer (FDR = 0.0051). Some DEGs shared target sites of the transcription factor, such as NFκB. (FDR = 0.0132) and PBX1 (FDR = 0.0158). Luteolin (enrichment = 0.87) can simulate the state of normal cells, while vancomycin (enrichment = -0.883) and Prestwick-1082 (enrichment = -0.882) might be potential pathogenic substances. CONCLUSIONS We hypothesize that glaucoma cells may be not only caused by the optic nerve cells themselves, but also caused by infections due to resistance decline. All these results may facilitate glaucoma treatment with a new breakthrough.
