Abstract
On the basis of variable-temperature single-crystal X-ray diffraction, rotational energy barrier analysis, variable-temperature/frequency dielectric response, and molecular dynamics simulations, here we report a new crystalline supramolecular rotor (CH3NH3)(18-crown-6)[CuCl3], in which the (H3C-NH3)+ ion functions as a smallest dual-wheel rotator showing bisected rotation dynamics, while the host 18-crown-6 macrocycle behaves as a stator that is not strictly stationary. This study also provides a helpful insight into the dynamics of ubiquitous -CH3/-NH3 groups confined in organic or organic-inorganic hybrid solids.

Abstract
Free accessible confined space and loose interaction are crucial for most solid-state ionic motions. Here, by using a near-spherical anion and a disc-shaped ammonium as two distinct but rigid building blocks, we report a new ionic crystal, (HMIm)3[La(NO3)6] (HMIm = 1-methyl-1H-imidazol-3-ium), in which the different confined spaces of three (HMIm)+ ions are fine-tuned over a broad temperature range. This effect can be utilized to modulate the dipolar polarization across a wide temperature/frequency range. Additionally, small-scale substitution of (HMIm)+ by its isomer of almost identical shape/size affords molecular solid solutions, which can further tune the dipolar polarization by varying the doping ratio. It is revealed that the differences in dipole moment and hydrogen bond rather than that of shape/size lead to a distorted crystalline environment for these solid solutions. Overall, we provide an exceptional model for understanding and regulating the dipole motion of polar aromatic molecules/ions in a crystalline environment.

Abstract
Objectives: To summarize the clinical phenotypes and the variation spectrum of ATP7B gene in Chinese children with Wilson's disease (WD) and to investigate their significance for early diagnosis. Methods: Retrospective analysis was performed on the clinical data of 316 children diagnosed as WD in Guangzhou Women and Children's Medical Center during the period from January 2010 to June 2021. The general situations, clinical manifestations, lab test results, imaging examinations, and ATP7B gene variant characteristics were collected. The patients were divided into asymptomatic WD group and symptomatic WD group based on the presence or absence of clinical symptoms at the time that WD diagnosis was made. The χ2 test, t test or Mann-Whitney U test were used to compare the differences between groups. Results: Among the 316 children with WD, 199 were males and 117 were females, with the age of 5.4 (4.0, 7.6) years at diagnosis; 261 cases (82.6%) were asymptomatic with the age of 4.9 (3.9, 6.4) years; whereas 55 cases (17.4%) were symptomatic with the age of 9.6 (7.3, 12.0) years. The main symptoms invloved liver, kidney, nervous system, or skin damage. Of all the patients, 95.9% (303/316) had abnormal liver function at diagnosis; 98.1% (310/316) had the serum ceruloplasmin lever lower than 200 mg/L; 97.7% (302/309) had 24-hour urine copper content exceeding 40 μg; only 7.4% (23/310) had positive corneal K-F rings, 8.2% (23/281) had abnormal MRI signals in the lenticular nucleus, and all of them had symptoms of damage in liver, kidney or nervous system. Compared with the group of symptomatic WD, asymptomatic group had higher levels of serum alanine aminotransferase and lower levels ceruloplasmin and 24-hour urine copper [(208±137) vs. (72±78) U/L, (55±47) vs. (69±48) mg/L, 103 (72, 153) vs. 492 (230, 1 432) μg; t=9.98, -1.98, Z=-4.89, all P<0.001]. Among the 314 patients completing genetic sequencing, a total of 107 mutations in ATP7B gene were detected, of which 10 are novel variants, and 3 cases (1.0%) had large heterozygous deletion (exons 10 to exon 11) in ATP7B gene. The percentage of missense mutation in asymptomatic WD children was significantly higher than that in symptomatic WD (81.5% (422/518) vs. 69.1% (76/110), χ²=8.47, P<0.05). WD patients carrying homozygous variant of c.2 333G>T had significantly low levels of ceruloplasmin than those not carrying this variant ((23±5) vs. (61±48) mg/L, t=-2.34, P<0.001). Conclusions: The elevation of serum ALT is an important clue for early diagnosis of WD in children, while serum ceruloplasmin and 24-hour urine copper content are specific markers for early diagnosis of WD. In order to confirm the diagnosis of WD, it is necessary to combine the Sanger sequencing with multiplex ligation-dependent probe amplification or other testing technologies.

Abstract
Objectives: To explore the GAA varient spectrum and the genotype-phenotype correlations in patients with glycogen storage disease type Ⅱ (Pompe disease, PD), as well as to estimate the disease incidence based on carrier rate of GAA varients in Guangzhou population. Methods: A total of 57 PD cases were retrospectively enrolled at Guangzhou Women and Children's Medical Center from January 1, 2010 to May 31, 2020. All patients presented symptoms before the age of 18 years. Each diagnosis was further confirmed by GAA enzyme activity and GAA variants. The carrier rate of GAA varients was calculated based on variants detected by whole exon sequencing among 2 395 healthy children in Guangzhou. Results: Among the 57 PD patients (including male 26, female 31),twenty-eight patients with infantile onset PD (IOPD) presented with progressive general muscle weakness and cardiomyopathy. The mean ages of symptom onset and diagnosis were (2.5±1.4) and (5.0±3.0) months, respectively. Twenty-six cases died in the first year after birth.Twenty-three patients with late onset PD (LOPD) presented with progressive muscle weakness. Seven of them had respiratory failure at diagnosis. The mean ages of symptom onset and diagnosis were (12.0±5.0) and (17.0±7.5) years, respectively. Six children with atypical IOPD showed motor delay, muscle weakness and cardiomyopathy. Their diagnosis was confirmed at 2.5-7.0 years of age. Among the 57 patients, 47 different variants were identified in the GAA gene. Three variants: c.797C>T, c.1109G>A and c.1757C>T were novel. c.1935C>A (25/114, 21.9%) and c.2238G>C (15/114, 13.2%) were the most common variants, detected in 57.1% of IOPD and 65.2% (15/23) of LOPD patients, respectively. Among the 28 IOPD patients, 26 cases (92.9%) carried at least one missense variant which indicated positive cross-reactive immunologic material (CRIM). The carrier rate of pathogenic variants in GAA gene among healthy children was 24/2 395. The estimated incidence of PD in this population is about 1/40 000. The frequencies of pseudodeficiency variants c.1726G>A and c.2065G>A homozygotes were 26.3% (15/57) and 35.1% (20/57) in PD patients, which were significantly higher than those (1.7% (40/2 395) and 3.9% (94/2 395)) in healthy children (χ²=151.2, 121.9; both P<0.01). Conclusions: PD presents as a spectrum, some as atypical IOPD. The c.1935C>A and c.2238G>C are common variants, correlated with IOPD and LOPD respectively. The c.796C>T and c.1082C>T are usually found in atypical IOPD. The majority of IOPD patients is predicted to be CRIM positive. The estimated incidence of PD is about 1/40 000.

Methods: The clinical and ultrastructural features of 3 patients with progressive neurodegenerative diseases were retrospectively analyzed from October 2014 to December 2016 in Department of Genetics and Endocrinology, Guangzhou Women and Children's Medical Center. The whole exon sequencing and Sanger sequencing were used to analyze the molecular genetics of the patients and their parents. Results: The probands were 11 years and 3 moths, 9 years and 1 month,10 years and 1 month old. All were normal at birth, and from 5-6 years old they began to develop "regression of cognition and motion, impaired vision". Physical examination at the first consultation: clear minded butignorant, unable to speak and understand instructions, unable to stand up and sit alone, unable to maintain postureupright. The brain magnetic resonance imaging(MRI) indicated diffuse cerebral and cerebellar atrophy, white matter damage. Blood biochemistry, lactic acid, acid-base balancewere normal. Electron microscopic examination of peripheral blood lymphocytes showed swelling of the nucleus, autophagy, intracellular massive deposits and abnormal vacuoles. Two compound heterozygous c.334C> T (p.Arg112Cys) and c.595C> T (p.Arg199Ter) mutations of CLN5 gene were identified in the two siblings, and the proband 3 was c.335G> A (p.Arg199His) homozyousmutation, which were inherited from their unaffected parents. Conclusions: The 3 cases with Finnish variant late infantileneuronal ceroid lipofuscinosises were normal at birth, cognitive and motor function was regressed at preschool age.Brain MRI showed whole brain atrophy, white matter lesions, there were no bovious difference from other neurodegenerative diseases. Blood biochemistry and pathological examination of lymphocytes had no specific changes. The pathogenic genes were CLN5,most are inherited in autosomal recessive way.

Abstract
Objective: To explore the prognosis and its risk factors in anti-neutrophil cytoplasmic antibodies (ANCA)-associated glomerulonephritis (AAGN) patients who needed initial renal replacement therapy (RRT). Methods: One hundred patients [54 females, 46 males, with a median age of 54(41, 60) years] with biopsy-proven AAGN and requiring initial RRT between January 1996 and December 2016 in Nanjing Jinling Hospital were included. Intensive immunotherapy indicated that the patients received corticosteroids in combination with cyclophosphamide or mycophenolate mofetil, or immunoadsorption (IA) or double filtration plasmapheresis (DFPP). The clinical and histological risk factors for renal survival were analyzed. Results: Forty-one patients were free of RRT after a median time of 1 (0.5, 2) month treatment (dialysis-independent group), and the remaining 59 patients were on maintenance dialysis (dialysis-dependent group). The multivariate logistic analysis revealed that the proportion of normal glomeruli <8% (OR=5.95, P=0.002) and global sclerotic glomeruli ≥50% (OR=4.87, P=0.003), and not receiving intensive immunotherapy (OR=7.81, P=0.004) were the risk factors for the renal recovery in these patients. During a median follow-up time of 22 (10, 50) months, 15 patients(36.6%) in the dialysis-independent group progressed into maintenance dialysis, and the 1 and 3 year renal survival rate were 86% and 60%, respectively. During a median follow-up time of 6 (2, 24) months, 12 (12%) patients died, among whom four patients died of therapy. The multivariate Cox regression analysis revealed that IA/DFPP treatment (HR=10.85, P=0.034) and low albumin level (HR=1.26, P=0.009) significantly associated with a higher risk of therapy-related death. Conclusions: The renal recovery rate in AAGN patients with initial RRT was low. The proportion of normal and global sclerotic glomeruli, receiving intensive immunotherapy or not were associated with renal outcome, and IA/DFPP treatment as well as lower albumin level were independently associated with therapy-related death.

Abstract
Metal-organic frameworks (MOFs) are very promising self-sacrificing templates for the large-scale fabrication of new functional materials owing to their versatile functionalities and tunable porosities. Most conventional metal oxide electrodes derived from MOFs are limited by the low abundance of incorporated metal elements. This study reports a new strategy for the synthesis of multicomponent active metal oxides by the pyrolysis of polymetallic MOF precursors. A hollow N-doped carbon-coated ZnO/ZnCo2 O4 /CuCo2 O4 nanohybrid is prepared by the thermal annealing of a polymetallic MOF with ammonium bicarbonate as a pore-forming agent. This is the first report on the rational design and preparation of a hybrid composed of three active metal oxide components originating from MOF precursors. Interestingly, as a lithium-ion battery anode, the developed electrode delivers a reversible capacity of 1742 mAh g-1 after 500 cycles at a current density of 0.3 mA g-1 . Furthermore, the material shows large storage capacities (1009 and 667 mAh g-1 ), even at high current flow (3 and 10 A g-1 ). The remarkable high-rate capability and outstanding long-life cycling stability of the multidoped metal oxide benefits from the carbon-coated integrated nanostructure with a hollow interior and the three active metal oxide components.

Abstract
Mesangial proliferative lupus nephritis may coexist with podocytopathy, but its clinical-morphological features, treatment response and outcomes have not been compared with mesangial proliferative lupus nephritis without podocytopathy. In this study, 125 biopsies of lupus nephritis patients showing mesangial proliferation with mesangial immune deposits were collected and divided into podocytopathy group (defined as podocyte foot process effacement (FPE) >50% with nephrotic syndrome (NS)) and mesangial group (FPE ≤50%, or FPE >50% without NS). Mesangial proliferation and tubular- interstitial lesions were semi-quantitatively analyzed. We found that the incidence of renal involvement as the onset symptoms ( P < .001), nephrotic syndrome ( P < .001), acute kidney injury ( P < .001), the degree of acute tubular- interstitial lesions ( P < .001), and renal relapse (51.6% vs. 23.7%, P = .005) were significantly higher in the podocytopathy group than in the mesangial group. In contrast, the incidence of arthritis ( P < .001), fever ( P = .042), low serum C4 ( P = .008) and hematuria ( P = .033) was significantly lower in the podocytopathy group than in the mesangial group. No patients developed end stage renal disease or death during a median follow-up of 64 (interquartile range (IQR) 37-103) months in the podocytopathy group and 53 (IQR 30-83) months in the mesangial group. In conclusion, mesangial proliferative lupus nephritis with and without podocytopathy should be subdivided into two separate classes of lupus nephritis.

Abstract
Homogeneously doped Yb3+ and Er3+ cerium-based coordination polymer (CP) microspheres have been successfully synthesized on a large scale through a simple solvothermal route with 2,5-pyridinedicarboxylic acid (2,5-H2PDC) as the organic linker. CeO2: Yb3+, Er3+ porous microspheres were obtained by annealing the corresponding CP microspheres at 600 °C for 4 h under atmospheric pressure. These as-prepared products were characterized by Powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), energy-dispersion X-ray (EDX) spectroscopy, Thermogravimetric (TG) and derivative thermogravimetric (DTG) analysis. The room temperature upconversion luminescent spectra of the as-prepared microspheres were carried out by 980 nm NIR light excitation. Interestingly, Yb3+ and Er3+ codoped CP microspheres give a single-band emission centered at 673 nm, while the CeO2: Yb3+, Er3+ microspheres give emission in green and red region, with red being the dominant emission. The emission intensity of the CeO2: Yb3+, Er3+ microspheres were much stronger than that of the Yb3+ and Er3+ codoped CP microspheres.

Abstract
We examined the expression pattern of the tumor sup-pressor gene RAS association domain family gene 1 (RASSF1) in lacri-mal gland carcinoma and analyzed its relationship with the oncogenesis and progression of tumors. Sixty-two patients (30 males, 32 females, average age = 47 ± 3.5 years) admitted with lacrimal gland carcinoma to the Department of Ophthalmology of our hospital between January 2012 and January 2014 were enrolled in this study. Based on tumor ma-lignancy, patients were classified into a malignant group (N = 25) and benign group (N = 37). Healthy lacrimal gland resections from trauma surgery (N = 35) were recruited as a healthy control group. Expres-sion profiles of RASSF1 in all groups were quantified using reverse transcription-polymerase chain reaction and western blotting. Recur-rence of lacrimal gland carcinoma was surveyed through postopera-tive follow-up. Expression levels of RASSF1 in samples from the ma-lignant and benign groups were significantly lower than those in the healthy group (P < 0.05). Furthermore, the malignant group showed lower RASSF1 expression than the benign group (P < 0.05). Postopera-tive follow-up identified 22 cases of recurrence in the malignant group, with a recurrence rate of 88%, while 15 cases in the benign group had a recurrence rate of 40.5%. A direct relationship exists between RASSF1 expression levels and the malignancy grade of lacrimal gland carci-noma. Patients with lower RASSF1 expression showed a higher recur-rence probability, indicating unfavorable prognosis. Therefore, measur-ing RASSF1 expression can be used as a diagnostic method for lacrimal gland carcinoma.

Abstract
The title compound, [Ru(C(14)H(12)N(2))(2)(C(18)H(14)N(4))](ClO(4))(2)·2H(2)O, consists of an Ru(II) complex cation, two perchlorate anions and two uncoordinated water mol-ecules. The Ru(II) ion is chelated by a 10,11,12,13-tetra-hydro-dipyrido[3,2-a:2',3'-c]phenazine ligand and two 2,9-dimethyl-1,10-phenanthroline ligands in a distorted octa-hedral geometry. The two uncoord-inated water mol-ecules are disordered over five positions, with an occupancy factor of about 0.4 for each site. A supra-molecular structure is formed by weak π-π inter-actions between neighbouring mol-ecules, with centroid-centroid distances of 3.618 (2) and 3.749 (2) Å.

Abstract
Currently, the detection of renal vascular lesions (VLS) in lupus nephritis (LN) mainly depends on biopsy examination, and lack surrogate biomarkers for clinical dynamic evaluation. The aim of the present study is to explore the correlation between circulatory endothelial damage biomarkers and VLS. Soluble E-selectin, thrombomodulin (TM) and vascular cell adhesion molecule-1 (VCAM-1) were measured by ELISA. TM and VCAM-1 levels both were significantly elevated in LN with VLS than in LN without VLS (P < 0.01). However, the serum E-selectin was not significantly changed in LN patients with and without VLS. A positive correlation was found between TM and serum creatinine (r = 0.617, P < 0.05) in patients with vascular lesions. In order to further analyse the relationship between TM level and severity degree of vascular lesions in LN patients, we subdivided the patients with vascular lesions into two groups: with thrombotic microangiopathy (TMA) and without TMA. TM level of the patients with TMA is significantly higher than those without TMA (P < 0.01). In conclusion, combined with renal pathological examination, monitoring the circulatory levels of TM and VCAM-1, can provide circulating biomarkers of VLS in LN patients.

Abstract
Amylin (islet amyloid peptide) plays a critical role in islet amyloidosis and in the development of beta-cell dysfunction in patients with diabetes; however, the involvement of amylin in renal amyloidosis has not been studied. For this reason, we surveyed 149 patients with biopsy-proven diabetic nephropathy (DN). The results were compared to 95 renal disease control patients, which included membranoproliferative glomerulonephritis, light-chain deposition, IgA nephropathy, and obesity-related glomerulopathy (ORG). Seventy-two of the 149 patients with DN showed amylin deposition in their renal tissue. Amylin was mainly distributed in the expanded mesangial area, Kimmelstiel-Wilson nodules, Bowman's capsule, and in blood vessels. The frequencies of mesangial proliferation, glomerular nodule lesions, and glomerular sclerosis were higher in DN patients with amylin deposits. Furthermore, the tubular interstitial lesions were more severe in these patients. Of the 95 disease-control patients, four with ORG were positive for renal amylin deposits. Our study has found renal amylin deposition in patients with DN and that the deposition was associated with disease severity. We suggest that strict metabolic control and reversing insulin resistance in patients with diabetes may blunt the process of amylin deposition in the kidney and possibly protect renal function in these patients.

Abstract
OBJECTIVE To investigate the interleukin-10 (IL-10) gene -592 A/C polymorphism in Chinese patients with lupus nephritis (LN) and evaluate the role of lL-10 in the pathogenesis and clinical/pathological diversity of LN. METHODS Polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) analyses were used to detect the IL-10 gene -592 A/C polymorphism in 265 LN patients and 100 ethnically matched controls. Frequencies of the genotypes were compared between LN patients and controls and among LN patients with different pathological classes. The clinical and pathological characteristics of the patients with different genotypes were also analyzed. Serum IL-10 levels of the patients were determined by ELISA. RESULTS No significant differences were found in the distribution of the polymorphism between healthy controls and LN patients. The parameters of disease activity index (DAI), percentage of positive serum anti-dsDNA antibodies, proteinuria and hematuria, and frequency of glomerular thrombi were all higher in patients with -592 AC/CC genotypes than those with AA genotype. AC/CC genotypes were more frequent in patients with LN-IV than in those with LN-II and Va. There was no significant difference in the serum IL-10 levels in patients with these three genotypes. CONCLUSION The IL-10 gene -592 A/C polymorphism appears to be associated with disease activity and renal pathology of LN, but not associated with LN susceptibility or serum IL-10 levels. Patients carrying the -592 C allele had a higher risk of diffuse proliferative glomerulonephritis, indicating the genetic influence of the IL-10 gene polymorphism in the renal lesions of LN.

Abstract
The antitumor antibiotic neocarzinostatin exhibits its main drug action by abstracting hydrogen from DNA deoxyribose with consequent strand breakage or related lesions. All biological activities of the drug derive solely from a nonprotein chromophoric substance (NCS-chrom) consisting of a novel epoxy-bicyclo-diyne-ene system. Thiol or sodium borohydride activates NCS-chrom into a labile, reactive species that induces DNA damage but causes inactivation of the drug in the absence of the target DNA. Mass spectrometric studies indicate that the isolated thiol-activated NCS-chrom product in the presence of DNA has the same molecular weight as the thiol-inactivated NCS-chrom product in the absence of DNA. No deuterium is incorporated into the chromophore from the deuterium-labeled sulfhydryl group. Since three deuterium atoms can be incorporated into the drug by treatment with sodium borodeuteride without DNA, adding an unlabeled DNA under parallel conditions permitted the ready identification of the activated NCS-chrom product that abstracted hydrogen from the DNA. Not only does the activated NCS-chrom product have the same structure as the inactivated drug without DNA, but two of the incorporated deuterium atoms have been substituted by hydrogen. With the aid of NMR spectrometry, the two replaced hydrogen atoms are found to be incorporated into the C-2 and C-6 positions of the bicyclo-diyne-ene ring of NCS-chrom and are derived neither from borodeuteride nor from the hydroxyl functions of the solvents. In accord with current proposals, the two hydrogens incorporated into the drug may come from closely opposed sites on the complementary strands of the DNA at which the drug is bound.(ABSTRACT TRUNCATED AT 250 WORDS)
