Abstract
Objective: To compare early outcomes between transurethral thulium laser vapoenucleation of prostate and transurethral thulium laser enucleation of prostate for the treatment of benign prostatic hyperplasia (BPH). Methods: Retrospective analysis was conducted on the clinical data of 1 638 BPH patients admitted to the Department of Urology of Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine from January 2018 to December 2021. There were 916 patients underwent transurethral thulium laser vapoenucleation of prostate (ThuVEP group) and 722 patients underwent transurethral thulium laser enucleation of prostate (ThuLEP group). The operation time, eliminated tissue weight, surgical complications, duration of post-operative catheter implantation were compared between the two groups. The improvement of International Prostate Symptom Score (IPSS), Quality of Life Index (QoL), maximum uroflow rate (Qmax) and post-void residual urine volume (PVR) at 1 month after operation was compared between the two groups. Results: There were no significant differences in age, preoperative and 1-month postoperative prostate volume, IPSS score, QoL score, Qmax, and PVR between the ThuVEP and ThuLEP group (all P>0.05). There were no significant differences in perioperative indicators such as operation time, cutting or enucleation time, tissue crushing time, tissue weight, hemoglobin change, catheter indwelling time, and postoperative hospital stay between ThuVEP group and ThuLEP group (all P>0.05). The incidence of minor gross hematuria after extubation in the ThuVEP group was 7.8% (56/916), which was lower than 9.4% (65/722) in the ThuLEP group (P=0.026); the incidence of temporary incontinence at 1 month after surgery was 5.2% (38/916) in ThuVEP group, lower than 11.9% (86/722) in ThuLEP group (P<0.001). A total of 3 patients (0.4%) in ThuLEP group required operative intervention for severe post-operation bleeding, but none of ThuVEP group suffered from this kind of surgical complications. Conclusions: ThuVEP has similar efficacy with ThuLEP for the treatment of BPH. ThuVEP can significantly reduce the incidence of post-operation temporary urine incontinence, and has much superiority in stanching bleeding.

Abstract
Nonalcoholic steatohepatitis (NASH) is an aggressive form of nonalcoholic fatty liver disease (NAFLD) characterized by steatosis-associated inflammation and liver injury. Without effective treatment or management, NASH can have life-threatening outcomes. Evaluation and identification of NASH patients at risk for adverse outcomes are therefore important. Key issues in screening NASH patients are the assessment of advanced fibrosis, differentiation of NASH from simple steatosis, and monitoring of dynamic changes during follow-up and treatment. Currently, NASH staging and evaluation of the effectiveness for drugs still rely on pathological diagnosis, despite sample error issues and the subjectivity associated with liver biopsy. Optimizing the pathological assessment of liver biopsy samples and developing noninvasive surrogate methods for accessible, accurate, and safe evaluation are therefore critical. Although noninvasive methods including elastography, serum soluble biomarkers, and combined models have been implemented in the last decade, noninvasive diagnostic measurements are not widely applied in clinical practice. More work remains to be done in establishing cost-effective strategies both for screening for at-risk NASH patients and identifying changes in disease severity. In this review, we summarize the current state of noninvasive methods for detecting steatosis, steatohepatitis, and fibrosis in patients with NASH, and discuss noninvasive assessments for screening at-risk patients with a focus on the characteristics that should be monitored at follow-up.

Abstract
BACKGROUND Despite substantial attention paid to the epidemic of nonalcoholic fatty liver disease (NAFLD) in adults, data on the burden and sexual dimorphism of NAFLD in Asian children have not yet been synthesized. METHODS We conducted a literature search of 735 references up to April 2021. Pooled analyses, stratified analyses and meta-regression were all performed. RESULTS Thirty-three study populations were finally included. Nine of them comprising 20 595 children showed an overall NAFLD prevalence of 5.53% (95% CI 3.46%-8.72%), in which, 36.64% (95% CI, 27.99%-46.26%) NAFLD subjects had elevated levels of ALT. The prevalence rate of NAFLD increased about 1.6-fold from 2004 to 2010 to the last decade. Male predominant trends were observed in paediatric NAFLD (boys: 8.18%, 95% CI 4.93%-13.26%; girls: 3.60%, 95% CI 1.60%-7.87%). Moreover, meta-analysis showed that after 10 years of age, boys were more prone to have NAFLD than girls (OR = 1.75; P = .0012). In addition, the pooled prevalence of NAFLD increased sequentially in normal-weight (1.49%, 95% CI 0.88%-2.51%, n = 2610), overweight (16.72%, 95% CI 7.07%-34.65%, n = 1265) and obese children (50.13%, 95% CI 41.99%-58.27%, n = 6434 individuals). After full covariate adjustment, the multivariate meta-regression also showed that boy percentage (P = .0396) and body mass index (P < .0001) were positively correlated with prevalent NAFLD. CONCLUSIONS In Asia, paediatric NAFLD is becoming prevalent over the recent decades, particularly among obese children and boys after 10 years old. The hormonal and chromosomal origins of paediatric NAFLD dimorphism need further investigation.

Abstract
Objective: To study the effects of specific isoforms of classic protein kinase C (cPKCs) on hypoxia-induced proliferation and the expression of ERK1/2 and Akt using drug intervention or virus transfection in vitro. Methods: Dynal MPC-1 magnetic particle concentrator was used to separate iron-containing pulmonary arterioles fragments, and the pulmonary artery smooth muscle cells (PASMCs) were primary cultured and identified. The cells were intervened by PKC agonist (PMA), PKCα inhibitor (safingol), PKCβⅠ inhibitor (Go6976) and PKCβⅡ inhibitor (LY333531) respectively, and the changes in protein expressions of cPKCs, and the phosphorylation levels of ERK1/2 and Akt were observed by immunoblotting under the condition of normal oxygen or hypoxia. The lentiviral vectors of PKCα and PKCβ were used to specifically knock-down the activity of target genes by virus transfection techniques, and Western blotting was used to observe the protein expressions of cPKCs, and the phosphorylation levels of ERK1/2 and Akt in hypoxia-induced PASMCs in mice. Results: With Brdu method, the proliferation of PASMCs induced by hypoxia was significantly inhibited by safingol, Go6976 and LY333531 by inhibiting cPKCα, βⅠ and βⅡ respectively. Compared with the hypoxic control group, the rates of Brdu positive cells were (7.35±0.26)% vs (11.28±0.43)%, (3.76±0.25)% vs (7.98±0.28)% and (4.12±0.46)% vs (7.78±0.53)%. We also observed that PMA could significantly promote the proliferation of PASMCs under normoxic condition. Compared with the normoxia control group, the Brdu-positive cell rates were (9.65±0.47)% vs (6.34±0.52)%, (9.34±0.38)% vs (5.42±0.21)% and (7.78±0.53)% vs (4.12±0.46)%. In addition, after transfection with PKCα or PKCβ lentiviral vector, the proliferation of PASMCs was significantly lower in hypoxia transfection group than in the control group. The rates of Brdu positive cells were (3.58±0.54)% vs (5.97±0.63)%, respectively. Using Western blotting, we also observed that after being inhibited by safingol, Go6976 and LY333531 respectively, the phosphorylation levels of ERK1/2 and Akt in PASMCs induced by hypoxia was significantly lower than the control group. After using safingol, the phosphorylation levels of ERK1/2 and Akt were (0.56±0.07) vs (1.08±0.13) and (0.49±0.04) vs (0.97±0.08). After using Go6976, the phosphorylation levels of ERK1/2 and Akt were (0.41±0.09) vs (0.79±0.10) and (0.48±0.09) vs (0.82±0.16), after using LY333531, the phosphorylation levels of ERK1/2 and Akt were (0.42±0.03) vs (0.87±0.06) and (0.34±0.07) vs (0.78±0.05). While PMA could promote the phosphorylation levels of ERK1/2 and Akt under normoxic condition, 1.25±0.12 vs 0.41±0.07 and 0.98±0.06 vs 0.37±0.08, respectively. Using transfection technique to specifically knock down the expression of cPKCα and β, we found that under hypoxic conditions, transfection of PASMCs could significantly lower the phosphorylation levels of ERK1/2, its phosphorylation level was 0.29±0.06 vs 0.76±0.05, with no evident change in the phosphorylation levels of Akt. Conclusions: Hypoxia may lead to phosphorylation of ERK1/2 by promoting the protein expression of cPKCα, cPKCβⅠ and cPKCβⅡ respectively, which eventually induces abnormal proliferation of PASMCs from the distal pulmonary arteries, participating in the development of hypoxic pulmonary hypertension (HPH) of the mice. Regulation of the expression of cPKCα, cPKCβⅠ and cPKCβⅡ may help to attenuate the formation of pulmonary vascular remodeling. Target therapy based on cPKCs is expected to be a new direction for HPH therapy in the future.

Abstract
BACKGROUND AND AIMS Nonalcoholic fatty liver disease (NAFLD) is associated with metabolic disorders. This study aimed to explore the role of metabolic disorders in screening advanced fibrosis in NAFLD patients. METHODS A total of 246 histologically-proven NAFLD patients were enrolled across 14 centers. We compared the severity of fibrosis in patients with different components of metabolic disorders. Based on standard noninvasive tests and metabolic disorders, we developed new algorithms to identify advanced fibrosis. RESULTS Metabolic syndrome (MetS) was frequent in NAFLD patients (133/246, 54%). Patients with MetS had a higher proportion of significant fibrosis (p=0.014) and higher LSM values (9.2 kPa, vs. 7.4 kPa, p=0.002) than those without MetS. Patients with more metabolic disorders had higher fibrosis stages (p=0.017). Reduced high-density lipoprotein cholesterol (odds ratio [OR]: 2.241, 95% confidence interval [CI]: 1.004-5.002, p=0.049) and raised fasting glucose (OR: 4.500, 95% CI: 2.083-9.725, p<0.001) were significantly associated with advanced fibrosis. Using these two metabolic disorders as a screening tool, a sensitivity, specificity and accuracy of 92%, 81% and 83% was achieved, respectively. With the new algorithms combining metabolic disorders with noninvasive measurements, the number of patients requiring liver biopsy was reduced, especially in combination with the Fibrosis-4 score and metabolic disorders (36% to 17%, p<0.001). In addition, this stepwise algorithm could achieve a high accuracy (85%) and high negative predictive value (93%). CONCLUSIONS Metabolic disorders should be taken into consideration in the diagnosis of advanced fibrosis. With further validation and investigation, new algorithms could be recommended in primary care units to spare patients from unnecessary referral and liver biopsies.

Abstract
BACKGROUND Although concomitant nonalcoholic steatohepatitis (NASH) is common in chronic hepatitis B (CHB), the impact of viral factors on NASH and the outcome of CHB patients concomitant with NASH remain unclear. We aimed to investigate the outcomes of NASH in CHB patients receiving antiviral treatment. METHODS In the post-hoc analysis of a multicenter trial, naïve CHB patients receiving 72-week entecavir treatment were enrolled. We evaluated the biochemical, viral and histopathological responses of these patients. The histopathological features of NASH were also evaluated, using paired liver biopsies at baseline and week 72. RESULTS A total of 1000 CHB patients were finally enrolled for analysis, with 18.2% of whom fulfilling the criteria of NASH. A total of 727 patients completed entecavir antiviral treatment and received the second biopsy. Serum HBeAg loss, HBeAg seroconversion and HBV-DNA undetectable rates were similar between patients with or without NASH (P > 0.05). Among patients with NASH, the hepatic steatosis, ballooning, lobular inflammation scores and fibrosis stages all improved during follow-up (all P < 0.001), 46% (63/136) achieved NASH resolution. Patients with baseline body mass index (BMI) ≥ 23 kg/m2 (Asian criteria) [odds ratio (OR): 0.414; 95% confidence interval (95% CI): 0.190-0.899; P = 0.012] and weight gain (OR: 0.187; 95% CI: 0.050-0.693; P = 0.026) were less likely to have NASH resolution. Among patients without NASH at baseline, 22 (3.7%) developed NASH. Baseline BMI ≥ 23 kg/m2 (OR: 12.506; 95% CI: 2.813-55.606; P = 0.001) and weight gain (OR: 5.126; 95% CI: 1.674-15.694; P = 0.005) were predictors of incident NASH. CONCLUSIONS Lower BMI and weight reduction but not virologic factors determine NASH resolution in CHB. The value of weight management in CHB patients during antiviral treatment deserves further evaluation.

Abstract
With the increasing incidence of obesity and metabolic syndrome worldwide, concomitant nonalcoholic fatty liver disease (NAFLD) in patients with chronic hepatitis B (CHB) has become highly prevalent. The risk of dual etiologies, outcome, and mechanism of CHB with concomitant NAFLD have not been fully characterized. In this review, we assessed the overlapping prevalence of metabolic disorders and CHB, assessed the risk of advanced fibrosis/hepatocellular carcinoma in CHB patients concomitant with NAFLD, and discussed the remaining clinical issues to be addressed in the outcome of such patients. We also explored the possible roles of hepatitis B virus in the development of steatosis and discussed difficultiesof histological evaluation. For CHB patients, it is important to address concomitant NAFLD through lifestyle management and disease screening to achieve better prognoses. The assessment of progressive changes and novel therapies for CHB patients concomitant with NAFLD deserve further research.

Abstract
BACKGROUND AND AIMS Nonalcoholic fatty liver disease, now renamed metabolic dysfunction-associated fatty liver disease (MAFLD), is common in obese patients. Intragastric balloon (IGB), an obesity management tool with low complication risk, might be used in MAFLD treatment but there is still unexplained heterogeneity in results across studies. METHODS We conducted a systematic search of 152 citations published up to September 2020. Meta-analyses, stratified analyses, and meta-regression were performed to evaluate the efficacy of IGB on homeostasis model assessment of insulin resistance (HOMA-IR), alanine aminotransferase (ALT), aspartate aminotransferase (AST), and gamma-glutamyl transpeptidase (GGT), and to identify patients most appropriate for IGB therapy. RESULTS Thirteen observational studies and one randomized controlled trial met the inclusion criteria (624 participants in total). In the overall estimate, IGB therapy significantly improved the serum markers change from baseline to follow-up [HOMA-IR: 1.56, 95% confidence interval (CI)=1.16-1.95; ALT: 11.53 U/L, 95% CI=7.10-15.96; AST: 6.79 U/L, 95% CI=1.69-11.90; GGT: 10.54 U/L, 95% CI=6.32-14.75]. In the stratified analysis, there were trends among participants with advanced age having less change in HOMA-IR (1.07 vs. 1.82). The improvement of insulin resistance and liver biochemistries with swallowable IGB therapy was no worse than that with endoscopic IGB. Multivariate meta-regression analyses showed that greater HOMA-IR loss was predicted by younger age (p=0.0107). Furthermore, effectiveness on ALT and GGT was predicted by basal ALT (p=0.0004) and GGT (p=0.0026), respectively. CONCLUSIONS IGB is effective among the serum markers of MAFLD. Younger patients had a greater decrease of HOMA-IR after IGB therapy.

Abstract
Recently, metabolic-associated fatty liver disease has become the world's highest prevalence of chronic liver disease. Moreover, it is closely related to metabolic syndrome and related diseases, bringing a huge disease burden. Previously, the global expert consensus on renaming for non-alcoholic fatty liver disease and the diagnostic criteria for metabolic-associated fatty liver disease has increased the certainty of further clinical research and practice. Presently, the research on metabolic-associated fatty liver disease is progressing rapidly, and the opinions and data based on clinical evidence are constantly updated. Hepatology international has published the "Asian Pacific Association for the Study of liver diseases' clinical guidelines on the management of metabolic-associated fatty liver disease" , which aims to promote clinical practice and improve the efficiency of clinical research. Here, we have translated the published recommendations into Chinese language, hoping to help most health professionals make clinical decisions.

Abstract
Abstract Objective To explore the impulse control and event-related potential (ERP) characteristics of patients with mental disorders caused by traumatic brain injury (TBI) in forensic psychiatry identification and to provide objective auxiliary indicators for forensic psychiatry identification. Methods Thirty patients (TBI group) with mental disorders caused by traumatic brain injury, who were identified as mild psychiatric impairment by judicial psychiatry, including 24 males and 6 females, as well as the thirty people in the control group participated in the study. All the participants completed Barratt Impulsiveness Scale-11 (BIS-11) and ERP induced by Go/NoGo tasks. BIS-11 and ERP data were collected and analyzed. Results The results of the BIS-11 showed that the total score and subscale scores of the TBI group were higher compared to the control group (P<0.05). Moreover, the TBI group exhibited significantly lower NoGo-N2 amplitude and lower NoGo-P3 amplitude than the control group. The NoGo-N2 amplitude was larger than the Go-N2 amplitude, and the NoGo-P3 amplitude was larger than the Go-P3 amplitude in both groups (P<0.05). Conclusion Traumatic brain injury could impair impulse control of mild psychiatric impairment patients, and the amplitudes of NoGo-N2 and NoGo-P3 could be important parameters to evaluate the impulse control of patients with mental disorders caused by traumatic brain injury.

Abstract
Achieving HBV DNA negative transformation and HBsAg clearance with effective antiviral therapy can reduce the incidence of HCC, but some patients are still at risk of developing HCC. Therefore, screening high-risk patients for close monitoring is essential to reduce the incidence of HCC. This paper reviews the occurrence of HCC, risk factors and risk prediction models of HBV DNA negative transformation and HBsAg clearance, and provides a basis for screening and follow-up management of high-risk group of HCC with chronic hepatitis B.

Abstract
With the progress in detection methods and the update of diagnostic and therapeutic concepts, more and more patients with primary biliary cholangitis (PBC) have been diagnosed and treated. A high proportion of PBC patients, however, progress to liver decompensation, with an increased risk of liver transplantation and death and a significant reduction in long-term survival. These patients need early diagnosis and urgent treatment. This article discusses how to identify the PBC patients with poor prognosis early from the aspects of biochemical response, disease features, and biomarkers, and reviews the progress in related complementary therapies and new drugs including Ocaliva, Fibrates, UDCA-derived drugs, and molecular targeted drugs.

Abstract
Objective: To study the acute effects of compound ambient air pollution on small airway lung functions among school children in Shanghai. Method: A longitudinal survey on lung functions was conducted among 233 school-children from three schools (A, B and C, located in innerring, mid-ring and outer-ring areas). Lung function test was performed once a week for 3 times respectively, among children in school A and B in Dec. 2013 and in school C in Dec. 2014. The fourth lung function test was tested in Jun. 2014 and May 2015 in the respective schools. Results: from the lung function would include items as: forced mid-expiratory flow at 25% of forced vital capacity (MEF(25%)), mid-expiratory flow at 50% of forced vital capacity (MEF(50%)), mid-expiratory flow at 75% of forced vital capacity (MEF(75%)) and mid-expiratory flow between 25% and 75% of the forced vital capacity (FEF(25%-75%)). Data regarding the daily air quality real-time of PM(2.5), PM(10), SO(2) and NO(2) in Dec. 2013, Dec. 2014, Jun. 2014 and May. 2015 from the three environmental monitoring spots and meteorological data from the Shanghai Meteorological Service system which were physically close to the three schools, were collected simultaneously. Linear mixed effect model was used to examine the levels of correlation between lung function indicators and ambient air pollutants. Results When confounding factors on meteorology and individuals were controlled, the lag effects and accumulated lag effects were found to have existed between the internal quarter rang (IQR) concentration of PM(2.5) and PM(10) in lag2 day and lag02 days, IQR concentration of SO(2) in lag02 day and IQR concentration of NO(2) lag0 day, when small airway lung functions like MEF(25%), MEF(50%), MEF(75%) and FEF(25%-75%)(P<0.05) were inspected. Results from the two air pollutants model analysis showed that SO(2) and NO(2) presenting interactive effects with PM(2.5), PM(10) and lag effects more significant than the individual SO(2) and NO(2), respectively (P<0.05). Conclusion: Contents on the ambient air pollutants as PM(2.5), PM(10), SO(2) and NO(2) were negatively associated with the lung functions in the small airways of children, in Shanghai.

Abstract
BACKGROUND Cirrhosis is a common complication of chronic hepatitis B. It remains unclear if viral and biochemical parameters at baseline affect virological response to entecavir and therefore warrant investigation. In the present study, we aimed to evaluate the efficacy of entecavir therapy by monitoring virological response at the end of the 3 rd month of treatment and try to figure out whether baseline factors could help predict it in a cohort of hepatitis B virus (HBV) compensated cirrhosis patients and to determine the cut-off value of a predicting parameter. METHODS A total of 91 nucleos(t)ide-naïve patients with HBV induced cirrhosis (compensatory stage) were enrolled in a prospective cohort. HBV DNA and alanine aminotransferase (ALT) were tested at baseline and monitored every 3-6 months after starting therapy. RESULTS Of all 91 patients, the median follow-up time was 12 (9-24) months. Overall, 64 patients (70.3%) achieved virological response in the 3 rd month. Univariate analysis showed that the 3 rd month virological response can be predicted by baseline HBV DNA levels (P < 0.001, odds ratio [OR]: 2.13, 95% confidence interval [CI]: 1.44-3.15), ALT value (P = 0.023, OR: 1.01, 95% CI: 1.00-1.01) and hepatitis B e antigen (HBeAg) negativity (P = 0.016, OR: 0.30, 95% CI: 0.11-0.80). Multiple regression analysis showed baseline HBV DNA level was the only parameter related to full virological response. Higher baseline HBV DNA strata indicated a higher probability that HBV DNA remains detectable at the 3 rd month (P = 0.001). Area under receiver operating characteristic curve for determining the 3 rd month virological response by baseline HBV DNA was 77.6% (95% CI: 66.7-85.2%), with a best cut-off value of 5.8 log 10 . CONCLUSIONS Baseline HBV DNA, HBeAg negativity, and ALT were independent factors contributing to virological response at the 3 rd month. Further, multiple regression showed that HBV DNA level was the only parameter predicting full virological response as early as the 3 rd month, in this cirrhosis cohort.

Abstract
BACKGROUND Thermotherapy has been known to be one of the most effective adjuvants to radiotherapy (RT) in cancer treatment, but it is not widely implemented clinically due to some limitations, such as, inadequate temperature concentrations to the tumor tissue, nonspecific and non-uniform distribution of heat. So we constructed arginine-glycine-aspartate peptides-conjugated gold nanorods (RGD-GNRs) that target the alpha(v) beta(3) Integrin (αvβ3) and investigate whether the photo-thermal effect of RGD-GNRs by near infrared radiation (NIR) could enhance the efficiency of RT in melanoma cancer cells. RESULTS RGD-GNRs could be seen both on the surface of the cell membranes and cytoplasm of A375 cells with high expression of αvβ3. After exposed to 808 nm NIR, RGD-GNRs with various concentrations could be rapidly heated up. Compared to other treatments, flow cytometric analysis indicated that RT + NIR + RGD-GNRs increased apoptosis (p < 0.001) and decreased the proportion of cells in the more radioresistant S phase (p = 0.014). Treated with NIR + RGD-GNRs, the radiosensitivity was also significantly enhanced (DMFSF2: 1.41). CONCLUSION Results of the current study showed the feasibility of using RGD-GNRs for synergetic RT with photo-thermal therapy. And it would greatly benefit the therapeutic effects of refractory or recurrent malignant cancers.

Abstract
A vacuum-cored hollow waveguide has been found to transmit 1064-nm, Q-switched Nd:YAG laser pulses. With this scheme, laser-induced air breakdown was completely suppressed, and the laser-induced damage threshold of the waveguide's inner coating was significantly increased. With a 1-m-long, 1-mm inner-diameter, cyclic olefin polymer-coated silver hollow waveguide, the maximum transmitted laser energy was as great as 158 mJ/pulse (20.1 J/cm(2)), at a repetition rate of 10 Hz in a 90 degrees -bent waveguide condition. The corresponding transmitted peak laser power was 17.6 MW. With the transmitted laser pulses, deep ablation of myocardium tissues was demonstrated in vitro.

Abstract
An oscillator-amplifier high-power Nd:YAG laser system was used for transmission of a single 50-ps-long pulse or a train of pulses through a cyclic olefin polymer-coated silver hollow-glass waveguide. The maximum energy that was transmitted was 150 mJ for the train of pulses and 40 mJ for the single pulse, from which followed a delivered power of 100 GW/cm(2) . The characteristics that were obtained make these waveguides promising for the delivery of high-power laser pulses in medical as well as other applications.

Abstract
Cyclic olefin polymer (COP) is newly used as the inner dielectric of infrared, hollow glass waveguides because of its low extinction coefficient in the mid-infrared region. A liquid-flow coating and dry-cure process are employed to form the COP layer on the inside of a silver-coated hollow glass tube. In the coating process, cyclohexane is chosen as the solvent of COP to form a smooth and uniform COP layer. It is shown that COP-coated silver hollow glass waveguides show low loss properties for CO(2), CO, and Er:YAG laser light when the thickness of the COP layer is properly chosen.

Abstract
Hollow fibers for CO(2) laser light have been fabricated with a cyclic olefin polymer as the inner dielectric. A film of cyclic olefin polymer was coated inside the glass capillary tubing by a simple liquid-flowing process. A polymer-coated fiber with a 700-microm bore showed a loss of 0.06 dB/m for CO(2) laser light because cyclic olefin polymer has low absorption at a 10.6-microm wavelength.
