Abstract
A 61-year-old male patient presented with blurred vision in the right eye for 1 day. The patient had previously undergone phacoemulsification with intraocular lens implantation (10 years ago) and intravitreal implantation of dexamethasone (due to uveitis) in the eye. There was edema in the inferior cornea, along with Descemet membrane folds. The rod-shaped dexamethasone implant was visible in the inferior anterior chamber. Without pupil dilation, the patient was asked to keep a supine position and avoid head tilting for 1 day. The implant spontaneously relocated into the vitreous cavity, resulting in a reduction of corneal edema. This suggests that the dislocation of the intravitreal implant into the anterior chamber may be caused by a local zonular abnormality, and the dislocated implant has the potential to reposition itself spontaneously.

Abstract
OBJECTIVE Risk perception is critical to the formation of individual health prevention behaviors. A long-term accurate perception of stroke recurrent risks is imperative for stroke secondary prevention. This study aims to explore the level of recurrence risk perceptions and the influential factors of inaccuracy between perceived and objective risk in first-ever ischemic stroke patients from a rural area. METHODS From May to November 2020, 284 first-ever ischemic stroke patients were conveniently recruited in a rural area of Henan Province, China. Perceived risk was measured based on self-reported using a numerical rating scale, whereas the objective risk was measured by the Essen Stroke Risk Score. Patients' perceived risk was compared with their objective risk and categorized as "Accurate," "Underestimated," and "Overestimated." The influencing factors of inaccuracy were further evaluated using multivariate regression analyses. RESULTS 46% of the participants underestimated their stroke risk, while 15.9% overestimated their risks. Patients who were younger (≤65 years), didn't worry about recurrent stroke, and had a low actual recurrent risk were more likely to underestimate their recurrent risk. Patients who were employed, had lower independence, and had greater anxiety were more likely to overestimate their recurrent risk. CONCLUSIONS The majority of participants were unable to accurately perceive their own risk of stroke recurrence. Patients' age, working status, worry about recurrent stroke, actual recurrent risk, level of dependence, and anxiety played a role in perception inaccuracy. PRACTICE IMPLICATIONS The findings could help healthcare providers gain a better understanding of the level and accuracy of recurrence risk perceptions among first-ever stroke patients in the rural area. Future counseling on the perceived risk of stroke recurrence and individual objective risk assessment could be conducted to help patients better understand their risk of recurrence. Individualized risk communication and multidisciplinary teamwork can be developed to improve the accuracy of recurrence risk perceptions and health behaviors.

Abstract
Objective: To evaluate the quality of life and influencing factors of patients with herpes zoster (HZ) seen in hospitals. Methods: Based on Zoster Brief Pain Inventory (ZBPI) and Five-level EuroQol Five-dimensional Questionnaire (EQ-5D-5L), a cross-sectional survey was conducted to evaluate the pain severity and quality of life of 332 HZ cases seen in 22 hospitals of Lu'an City (Anhui Province), Zibo City (Shandong Province) and Tongchuan City (Shaanxi Province) from October to December 2021. The censored least absolute deviations (CLAD) model was used to analyze the related factors affecting the changes of patients' health utility values. Results: The 45.5% of 332 HZ cases were male. The median (Q1,Q3) age was 59 (50, 68) years. 59.64% of them assessed by ZBPI had moderate to severe pain in the past 24 hours (worst pain score≥5), and that of PHN cases was 84.8%(39/46). 77.7% (258/332), 77.4% (257/332) and 74.1% (246/332) of all patients reported that pain interfered with sleep, mood and general activities, respectively. Aging [β40-49y (95%CI)=-0.11 (-0.15, -0.08); β50-59y (95%CI)=-0.03 (-0.05, 0.00); β60-69y (95%CI)=-0.09 (-0.12, -0.06); β70-90y(95%CI)=-0.16 (-0.19, -0.12)], working status (unemployed) [βfarmer (95%CI)=0.15 (0.13, 0.18); βretirees(95%CI)=0.21 (0.18, 0.24); βemployee (95%CI)=0.13 (0.10, 0.16) ], complications[βPHN (95%CI)=-0.08 (-0.13, -0.04); βother complications (95%CI)=-0.12 (-0.15, -0.08)], within 30 days after onset [β(95%CI)=-0.01 (-0.03, 0.01)] and treatment [βother complications (95%CI)=-0.09 (-0.11, -0.06)] were related factors for the decline of health utility value (all P values <0.05). Conclusions: More than half of the patients with HZ had moderate to severe pain in the past 24 hours, which had a serious negative impact on the physical and mental health of the patients. Elderly patients, acute patients and patients with complications had lower health utility values and worse health status. We suggest that eligible people be vaccinated with HZ vaccine as soon as possible.

Abstract
Objective: To analyze the clinical and genetic characteristics of 33 children with congenital lipoid adrenal hyperplasia (CLAH) caused by StAR gene defects. Methods: The clinical, biochemical, genetic, and follow-up (until December 2021) data of 33 children diagnosed with CLAH from 2006 to 2021 were retrospectively analyzed in Xinhua Hospital, Shanghai Jiao Tong University School of Medicine. Results: Of the 33 children with CLAH, 17 had a karyotype of 46, XX and 16 had a karyotype of 46, XY; 31 were female and 2 were male by social gender. Classic type and non-classic type were found in 30 and 3 children respectively. The age at diagnosis was 9.0 (3.0, 34.5) months. All the 30 cases with classic CLAH presented within the first year of life with skin hyperpigmentation (28 cases, 93%), vomiting and(or) diarrhea (19 cases, 63%), no increase in body weight (8 cases, 27%), elevated adrenocorticotropic hormone levels (21cases (70%)>275 pmol/L), decreased cortisol levels (47 (31,126) nmol/L), hyponatremia ((126±13) mmol/L), hyperkalemia ((5.7±1.1) mmol/L), and normal 17α-hydroxyprogesterone levels (30 cases, 100%). All these with classic CLAH exhibited female external genitalia. Three children with non-classic CLAH (including 2 cases of 46, XY and 1 case of 46, XX) also showed signs and symptoms of adrenal insufficiency, but 2 of them had an age of onset later than 1 year of age, including 1 case of 46, XY with male external genitalia and 1 case of 46, XX with female external genitalia. The other 46, XY patient with non-classic CLAH presented with adrenal insufficiency at 2 months of age, showing micropenis and hypospadias. In the 17 females with 46, XX, 4 older than 10 years of age showed spontaneous pubertal development. A total of 25 StAR gene pathogenic variants were identified in 33 patients, with p.Q258* (18/66, 27%), p.K236Tfs*47 (8/66, 12%) and p.Q77* (6/66, 9%) being the common variantion. Six novel variants were found, including c.358T>G, c.713_714del, c.125del, c.745-1G>A, c.179-2A>C, and exon 1 deletion. Conclusions: Patients with classic CLAH typically present with signs and symptoms of primary adrenal insufficiency in the early infancy period and female external genitalia. p.Q258*, p.K236Tfs*47 and p.Q77* are common variants in CLAH patients.

Abstract
In recent years, frequent haze episodes have resulted in the deterioration of air quality of the Fenwei Plain during winter and holidays. Besides coal combustion and industrial emissions, the topography and climate of the Fenwei Plain were also the main causes of the haze. The samples were collected in Linfen of Fenwei Plain during the Spring Festival from February 2 to February 13, 2019. The 13 elements(Li, Be, Ti, Rb, Sc, Y, La, Ce, Zr, V, Tl, U, and Sn) in PM2.5 were determined by inductively coupled plasma mass spectrometry(ICP-MS). Combined with the meteorological data, the spatial and temporal distribution of pollutants and potential source analysis were evaluated by cluster analysis and backward trajectory. The average concentration of SO2 was 58.39 μg·m-3 during the sampling period, which exceeded the 24 h average mass concentration limit(50.00 μg·m-3) of national ambient air quality standard(GB 3095-2012). The average concentrations of O3, NO2, and CO was 52.15 μg·m-3, 29.02 μg·m-3, and 2.29 mg·m-3, respectively. The results showed that SO2 was the dominated pollutant. NO2 and CO were mainly affected by diffusion from urban areas. The backward trajectory analysis indicated that the basin topography of the Fenwei Plain may be the main cause of the haze. The analysis of potential source contribution function(PSCF) of soil sources showed that the potential dominated areas included Northern Shaanxi, southern Gansu and Southern Ningxia., which were mainly affected by the monsoon climate.

Abstract
BACKGROUND The proper growth and development of tea plants requires moderately acidic soils and relatively low calcium levels, and excessive calcium at high pH can damage tea plant roots. To reveal the effects of calcium on the responses of tea plant to three pH levels (3.5, 5.0 and 6.5), a repeated test of two factors was designed. RESULTS Root growth and elemental analysis indicated that excessive calcium improved the growth of tea roots at low pH conditions, whereas it did not harm the growth of tea roots under normal and high pH conditions, especially at pH 6.5. Excessive calcium antagonized the absorption and utilization of magnesium by tea plants. Gas chromatography-mass spectrometry results showed that the addition of Ca2+ resulted in the primary metabolism in roots being more active at a low pH level. By contrast, it had obvious adverse effects on the accumulation of root metabolites with high calcium treatment at normal or high pH. Differential metabolites identified using ultra-performance liquid chromatography quadrupole time of flight mass spectrometry indicated that flavonoids demonstrated the largest number of changes, and their biosynthesis was partially enriched with excessive calcium at low and high pH conditions, whereas it was down-regulated under normal pH conditions. Kaempferol 3-(2'-rhamnosyl-6'-acetylgalactoside) 7-rhamnoside, quercetin 3-(6'-sinapoylsophorotrioside) and delphinidin 3-(3'-p-coumaroylglucoside) showed the greatest increase. The results of gene expression related to root growth and calcium regulation were consistent with root growth and root metabolism. CONCLUSION The overall results demonstrated that high Ca concentrations further aggravate the detrimental effects of high pH to tea roots. However, it is interesting that excessive calcium reduced the harm of a low pH on tea root growth to some extent. © 2021 Society of Chemical Industry.

Abstract
The clinical and biochemical data and gene sequencing results of patients with carnitine palmitoyltransferase 1A deficiency were analyzed, in order to improve the understanding of the disease. Six patients (5 males and 1 female, aged from 1 to 8 years old) with carnitine palmitoyltransferase 1A deficiency from Department of Pediatric Endocrinology and Genetic Metabolism, Xinhua Hospital between 2008 and 2019 were included. Two cases were detected by neonatal screening and had no clinical symptoms. The remaining 4 cases all showed seizures induced by fever, vomiting or diarrhea. All the 6 patients showed increased serum free carnitine (C0), decreased hexadecanoylcarnitine (C16) and octadecanoylcarnitine (C18), and increased C0/(C16+C18). Meanwhile, compound heterozygous mutations of CPT1A gene were detected in all 6 patients, of which 2 were reported mutations (c.281+1G>A and c.968-8C>T), and 10 were new mutations. The new mutations included 6 missense mutations, 1 nonsense mutation, 1 deletion mutation and 2 splicing mutations. Detection of free carnitine and acyl carnitine by tandem mass spectrometry is helpful for early screening and diagnosis of carnitine palmitoyltransferase 1A deficiency.

Abstract
Objective: To investigate the current status of the diagnosis and treatment of pulmonary cryptococcosis in respiratory medicine and improve the understanding of the clinical characteristics of HIV-negative pulmonary cryptococcosis in China. Methods: A prospective multi-center open cohort study was designed to screen for pulmonary cryptococcosis in the general wards and intensive care units of the Department of Respiratory Diseases in 22 hospitals. The HIV-negative patients with positive cryptococcal etiological diagnosis based on smear culture, antigen detection and histopathology were enrolled in the study. The clinical data of enrolled patients were collected and analyzed. Results: A total of 457 cases of pulmonary cryptococcosis were enrolled, among which 3.28% (15/457) were disseminated infections. The case fatality rate was 0.88% (4/457). The majority of the cases were diagnosed by histopathological examinations (74.40%, 340/457) and cryptococcus antigen detection (37.64%, 172/457). Patients with pulmonary cryptococcosis accounted for 2.04‰ (457/223 748) of the total hospitalized patients in the Department of Respiratory Diseases during the same period, and the ratio was the highest in south and east China. Meanwhile, 70.24% (321/457) of the patients had no underlying diseases, while 87.75% (401/457) were found to have immunocompetent status. Cough and expectoration were the most common clinical symptoms in patients with pulmonary cryptococcosis. However, 25.16% (115/457) of the patients had no clinical symptom or physical signs. In terms of imaging features on pulmonary CT, multiple pulmonary lesions were more common than isolated lesions, and there were more subpleural lesions than perihilar or medial lesions. Morphologically, most of the lesions were middle-sized nodules (1-5 cm) or small-sized nodules (3 mm to 1 cm). The sensitivity of serum cryptococcus antigen test was 71.99% (203/282). Moreover, antigen-positive patients differed from antigen-negative patients in terms of basic immune status, clinical symptoms, imaging features and infection types. Meanwhile, immunocompromised patients differed from immunocompetent patients in terms of clinical symptoms, physical signs, infection-related inflammation indicator levels, imaging features, serum cryptococcus antigen positive rate and prognosis. Conclusions: The majority of cases of HIV-negative pulmonary cryptococcosis in China had no underlying disease or immunocompromised status, and the overrall prognosis was favorable. However, early diagnosis of HIV-negative pulmonary cryptococcosis remains challenging due to the complicated manifestations of the disease.

Abstract
CRISPR-Cas systems have revolutionized genome editing across a broad range of biotechnological endeavors. Many CRISPR-Cas nucleases have been identified and engineered for improved capabilities. Given the modular structure of such enzymes, we hypothesized that engineering chimeric sequences would generate non-natural variants that span the kinetic parameter landscape, and thus provide for the rapid selection of nucleases fit for a particular editing system. Here, we design a chimeric Cas12a-type library with approximately 560 synthetic chimeras, and select several functional variants. We demonstrate that certain nuclease domains can be recombined across distantly related nuclease templates to produce variants that function in bacteria, yeast, and human cell lines. We further characterize selected chimeric nucleases and find that they have different protospacer adjacent motif (PAM) preferences and the M44 chimera has higher specificity relative to wild-type (WT) sequences. This demonstration opens up the possibility of generating nuclease sequences with implications across biotechnology.

Abstract
Background Accumulating evidences have shown that miRNAs are directly or indirectly involved in a variety of biological processes, and closely associated with diverse human diseases, including cardiovascular diseases. SNPs locating within pri/pre-miRNA can affect miRNA processing and binding ability of target genes. MiR-27a, miR-26a-1 miR-100, miR-126 and miR-218 were reported to be associated with pathogenesis of myocardial infarction (MI). Here we aimed to evaluate the potential association of five polymorphisms in these pri/pre-miRNAs with individual susceptibility to MI in a Chinese Han population. Methods Genotyping was performed in 287 MI cases and 646 control subjects using polymerase chain reaction-ligase detection reaction (PCR-LDR) method. The association of these SNPs with MI risk was performed with SPSS software. Results In a logistic regression analysis, we found that AG heterozygote (OR = 0.40, 95% CI = 0.21-0.76, Pa = 0.005) or AA homozygote (OR = 0.40, 95% CI = 0.22-0.75, Pa = 0.004) of pre-miR-27a rs895819 had a reduced susceptibility to MI in comparison with GG homozygote. Similarly, a reduced risk of MI was detected when the AG and AA genotypes were combined (OR = 0.40, 95% CI = 0.22-0.74, Pa = 0.003). However, no significant association between pri-miR-26a-1 pri-miR-100, pri-miR-126 and pri-miR-218 polymorphisms and MI risk was observed under the allelic and established genetic models. Further stratified analysis of pre-miR-27a rs895819 revealed a more significant association of AG + AA genotypes with MI risk among younger, male and smoking subjects. Interestingly, AG and AA genotypes of the rs895819 polymorphism conferred about 0.17 mmol/L and 0.18 mmol/L increase in HDL-C levels compared to GG genotype. Conclusions Our findings suggest that the pre-miR-27a rs895819 polymorphism is associated with MI susceptibility in the Chinese Han population, which probably due to influence the HDL-C levels.

Abstract
OBJECTIVE To detect large genomic deletions or duplications of ornithine transcarbamylase (OTC) gene by multiplex ligation-dependent probe amplification (MLPA). METHOD Thirty cases of suspected OTC deficiency (OTCD) patients based on tandem-mass spectrum results were recruited in Xinhua Hospital from 2012 to 2014, among whom 13 were male and 17 were female. Sanger sequencing of OTC gene revealed mutations in 23 cases. MLPA was performed in the patients whose previous Sanger sequencing failed to detect any disease-causing mutation. The samples were treated via the steps of DNA degeneration, the probe hybridization, connecting the hybridization probe, PCR amplification and capillary electrophoresis. The data were analyzed using Coffalyser software. RESULT Abnormal MLPA results were found in 5 patients without mutation detected in previous Sanger sequencing. Patient 1, a 9-year old girl, had a heterozygous deletion of Exon 2-4. Patient 2, a male newborn, died 10 days after birth. The examination of the mother's sample by MLPA revealed a heterozygous duplication of exon 2-6. Patient 3, a 10-day old boy, was found to harbor a hemizygous deletion of exon 7-10. Patient 4, a 2-year old girl, harbored a heterozygous deletion of exon 1-4. The fifth patient died at the age of 6 years, and his mother carried a heterozygous duplication of exon 1-4. CONCLUSION MLPA can be helpful in detecting the OTC gene defects, particularly for OTCD patients without mutation detected by Sanger sequencing.

Abstract
OBJECTIVE To explore the clinical and genetic characteristics of an infant with isolated 17, 20-lyase deficiency. METHOD The clinical, biochemical and genetic characteristics were analyzed in an 8-month-old infant with 46, XY gonadal dysgenesis who presented predominantly the female external genitalia. RESULT The infant was referred because of"masses in bilateral inguinal region and 46, XY gonadal dysgenesis". He was normotensive. Laboratory tests revealed elevated levels of progesterone and 17-hydroxyprogesterone. The detailed parameters are as follows: progesterone 29.35(reference range 0.09-1.0)nmol/L, 17-hydroxyprogesterone 10.9(reference range 0.6-2.6)nmol/L, testosterone 0.7(reference range 0.1-3.1)nmol/L, dehydroepiandrosterone sulfate <0.15(reference range 0.80-5.6)mg/L, androstenedione <0.3 (reference range 0.6-3.1) μg/L, luteinizing hormone 6.6(reference range 0.6-1.7)U/L, follicle stimulating hormone 1.8 (reference range 0.5-3.7)U/L, estradiol 37.66(reference range 73.4-146.8)pmol/L. The patient had normal levels of serum sodium, potassium, corticosteroid and plasma adrenocorticotropic hormone. Genomic DNA was extracted from the leukocytes of peripheral blood of the patient and subjected to next generation sequencing (NGS) for testing more than 200 sexual development related genes. Sanger sequencing was used to confirm the results of NGS. Genetic analysis revealed that the patient harbored compound heterozygous mutations of c. 1226C>G (p.Pro409Arg, P409R) and c. 707T>G (p.Val236Gly, V236G) in CYP17A1 gene derived from paternal and maternal allele. V236G was a novel mutation predicted to be pathogenic. The infant was diagnosed as isolated 17, 20-lyase deficiency combined with clinical and molecular characteristics of CYP17A1 gene. CONCLUSION We have identified the compound heterozygous mutations of P409R and V236G in the CYP17A1 gene in one infant with isolated 17, 20-lyase deficiency. He presented with 46, XY gonadal dysgenesis, normal blood pressure and elevated concentration of progesterone and 17-hydroxyprogesterone.

Abstract
Fertilized soils have large potential for production of soil nitrogen oxide (NOx=NO+NO2), however these emissions are difficult to predict in high-temperature environments. Understanding these emissions may improve air quality modelling as NOx contributes to formation of tropospheric ozone (O3), a powerful air pollutant. Here we identify the environmental and management factors that regulate soil NOx emissions in a high-temperature agricultural region of California. We also investigate whether soil NOx emissions are capable of influencing regional air quality. We report some of the highest soil NOx emissions ever observed. Emissions vary nonlinearly with fertilization, temperature and soil moisture. We find that a regional air chemistry model often underestimates soil NOx emissions and NOx at the surface and in the troposphere. Adjusting the model to match NOx observations leads to elevated tropospheric O3. Our results suggest management can greatly reduce soil NOx emissions, thereby improving air quality. Soil NOx emissions can significantly impact air quality in agricultural regions, particularly high temperature fertilized systems. Here, the authors investigate NOx emissions in one such system in California and suggest that the NOx emissions are the highest ever observed, with implications for air quality.

Abstract
Phenylketonuria (PKU) is the most frequent inherited disorder of amino acid metabolism. In our previous work, we investigated the role of NADPH oxidase (NOX) in a Pahenu2-BTBR PKU mouse model, and an in vitro cell culture model of PKU. In the current study, we evaluated various oxidative stress parameters, namely total antioxidant capacity (T-AOC), glutathione (GSH) and maleic dialdehyde (MDA) in the plasma of 40 PKU children, for further investigating the oxidative molecular regulation mechanism of NOX in PKU. It was observed that T-AOC and GSH markedly decreased in PKU as compared with the control group (P<0.01), and seemed to correlate negatively with Phe level. However, there was no statistical difference in MDA level among the three groups. And 8-isoprostane in the blood samples of PKU2 groups was slightly higher than control group (P<0.05). Additionally, mRNA levels of subunits of NOX included p47(phox) and p67(phox) significantly increased in PKU group (P<0.01). These results reflected that NOX is the important source of reactive oxygen species and is involved in the oxidative molecular regulation mechanism in PKU, which shows a new perspective toward understanding the biological underpinnings of PKU.

Abstract
Cucurbit[n]urils are a family of molecular container hosts bearing a rigid hydrophobic cavity and two identical carbonyl fringed portals. They have attracted much attention in supramolecular chemistry because of their superior molecular recognition properties in aqueous media. This review highlights the recent advances and challenges in the field of cucurbit[n]uril-based coordination chemistry. It not only presents progress in the knowledge of such macrocyclic compounds, which range from simple to complicated architectures, but also presents new routes of synthesis and their advantages in hybrid porous solids. The concept of structure "inducer" for their structural design to achieve predictable structures and controlled pores is described. The large pore sizes and hydrophobic cavities of these compounds that lead to unprecedented properties and potential applications are also discussed.

Abstract
There is intensive interest in the design of tubular channels because of their novel structures and various applications in a variety of research fields. Herein, we present a series of coordination-driven Q[7]-derived organic nanochannels using an anion-induced strategy under different acid concentrations. An advantage of this approach is that the tubular channels not only retain the original character of the parent macrocyclic receptors but also provide deep hydrophobic cavities possessing guest binding sites. Importantly, this study also emphasizes the efficiency of the macrocyclic receptors in providing a tubular hydrophobic cavity by directly stacking on top of one another with the anion-fixed and by acid control. The resulting combination of hydrogen bonding, C-H···Cl, and ion-dipole interactions helps to stabilize these supramolecular architectures. Such systems are both tunable and versatile and allow for interconvertibility in the construction of nanochannels based on these macrocyclic receptors.

Abstract
In the title compound, {(C8H20N2)[Al(HPO4)(PO4)]}n, the AlIII atom is coordinated by four O atoms from two HPO42− and two PO43− groups in a distorted tetrahedral geometry. Each AlO4 unit shares four O atoms with four adjacent PO4 units, leading to an anionic chain along [100]. The negative charge of the chain is compensated by doubly protonated camphoric amine cations. N—H⋯O hydrogen bonds connect the cations and the anionic chains. O—H⋯O hydrogen bonds are present in the chain.

Abstract
Fly ash was investigated as a catalyst in the oxidation of p-nitro phenol (PNP) with H2O2 at ambient temperature and pressure. The physical and chemical properties of fly ash were analyzed. The effects of fly ash composition, pretreatment methods and other parameters (such as dosage, pH, reaction time and oxidant concentration) on PNP removal rate were studied. It was found that fly ash with larger specific surface area and higher carbon content demonstrated higher catalytic activity. Heat treatment (350 degrees C) on fly ash could effectively improve the PNP removal rate. With an initial H2O2 concentration of 200 mg/L, 60 g/L heat-treated fly ash could remove 62.38% PNP at 25 degrees C, pH = 2. Specific surface area, carbon and metal oxide contents of fly ash play an important role in the catalysis process. The adsorption control experiment showed that adsorption was the main effect (65.97%) in the catalysis process. The activity of the catalyst gradually increased during its reuse. The PNP removal rate could reach 82.47% and 98.72% in the second and third rounds of reuse, respectively. The removal rate remained at about 99% in the rest 9 rounds of reuse. And the catalytic properties decreased after 12 times uses.

Abstract
BACKGROUND AND PURPOSE Theoretical study had shown that compared with a single pulse, a duplicate pulse could improve the efficiency of lithotripsy. We conducted a series of studies to validate this idea. MATERIALS AND METHODS The experimental study in vitro and in vivo used a lithotripsy machine with duplicate, single, and electromagnetic pulses. RESULTS Use of a duplicate pulse improved the wastage of the model stones about 44.15% and the efficiency of lithotripsy about 44.76%. In pigs, the efficiency of lithotripsy was greater with a duplicate pulse than with single and electromagnetic pulses. CONCLUSION Compared with single and electromagnetic pulses, duplicate pulses could improve the efficiency of lithotripsy by more than 40%.

Abstract
The urinary concentration of pseudouridine, primarily a breakdown product of tRNA, was determined by high-performance liquid chromatography in 33 patients with small cell lung cancer (SCLC), 18 patients with non-small cell lung cancer (NSCLC), 18 patients with benign pulmonary diseases (eg, TB, COPD), and 16 healthy controls. The mean urinary pseudouridine concentration levels of the patients with SCLC, NSCLC, benign pulmonary disease and the healthy controls were 22.7 +/- 11.8, 15.6 +/- 6.0, 13.4 +/- 3.6, 12.1 +/- 3.2 nmol/mumol creatinine (mean +/- SD), respectively. The mean urinary pseudouridine concentration was significantly higher in patients with SCLC than that in patients with NSCLC, benign pulmonary disease and in the healthy controls. There was no significant difference in the urinary pseudouridine levels of patients with NSCLC and healthy controls or patients with benign pulmonary disease. Urinary pseudouridine levels above 18.5 nmol/mumol creatinine (mean value +/- 2SD for healthy controls) were noted in 54.5% of patients with SCLC, including 11 of 17 (64.7%) in extensive stage and seven of 16 (43.8%) in limited stage, and 27.8% of the patients with NSCLC. Of the 12 patients with SCLC who had follow-up urinary samples taken in series during chemotherapy courses, there was considerable urinary pseudouridine level change which paralleled the change in clinical response. Although urinary pseudouridine is not a specific marker for SCLC, it represents the tumor burden and reflects the clinical status. These findings indicate that urinary pseudouridine may be a useful tumor marker in patients with SCLC.

Abstract
Anterior segments of human donor eyes were perfused with culture medium at a perfusion pressure of 15 mm Hg in a 5% carbon dioxide environment at 37 degrees C. After determination of a baseline facility of outflow, the perfusion chamber contents were exchanged with either drug vehicle or ethacrynic acid, at concentrations ranging from 0.01 to 0.25 mmol/L, after which postdrug facility was measured in the continuous presence of drug vehicle or ethacrynic acid. Ethacrynic acid increased facility of outflow from 28% to 105% at ethacrynic acid concentrations of 0.01 to 0.25 mmol/L, respectively. No morphologic correlate of the facility increase was observed with 0.01-mmol/L ethacrynic acid, nor were there any signs of cellular toxic effects. At 0.1 mmol/L, separations between trabecular meshwork cells and breaks between inner-wall cells were observed. At 0.25 mmol/L, focal areas of cell swelling and necrosis were noted. This study demonstrated that ethacrynic acid increases outflow facility in the aged human eye at concentrations that produce no apparent toxic effects. Therefore, ethacrynic acid may potentially prove useful in the treatment of glaucoma.
