Abstract
Signal transducer and activator of transcription 3 (STAT3) have been highlighted in cancer regulation. Its roles in Cholangiocarcinoma (CCA) arising from the choledochal cyst (CC) were unclear. Here, we attempted to elucidate the roles of STAT3 in CCA-CC and explore its mechanism. A total of 20 patients with CCA arising from CC, that underwent CC excision in the infant stage were included. The expressions of STAT3, miR200c and c-Myb in clinical samples were assessed by RT-qPCR and/or western blot. Their expression correlations in tumor tissues were evaluated by Pearson correlation analysis. Their roles in CCA cell migration and invasion were investigated by gene silence using siRNA or miRNA inhibitor mediated approach and MEK activator. The expression levels of EMT, metastasis and MEK/ERK pathway-related proteins were checked by western blot. The high expressions of STAT3 and c-Myb, and low expression of miR200c were detected in CCA samples. We defined the transcription inhibition of STAT3 in miR200c expression and the negative correlation between miR200c and c-Myb expression. Silence of STAT3 increased miR200c expression and retarded the migration and invasion of CCA cells, accompanied by decreased levels of Vimentin, N-cadherin, MMP2 and MMP9, and elevated expression of E-cadherin, resulting in inactivating MEK/ERK pathway. MiR200c inhibitor reversed the changes induced by STAT3 silence, which was restored by si-c-Myb. MEK activator significantly reversed the inactivation of the MEK/ERK pathway induced by si-STAT3+miR200c inhibitor+si-c-Myb. In summary, the silence of STAT3 suppressed metastasis and progression of CCA cells by regulating miR200c through the c-Myb mediated MEK/ERK pathway, suggesting STAT3 is the effective target for CCA arising from CC.

Abstract
The preferential capture of ethane (C2H6) over ethylene (C2H4) presents a very cost-effective and energy-saving means applied to adsorptive separation and purification of C2H4 with a high product purity, which is however challenged by low selectivity originating from their similar molecular sizes and physical properties. Substituent engineering has been widely employed for selectivity regulation and improvement, but its effect on C2H6/C2H4 separation has been rarely explored to date. In this work, four isoreticular coordination framework compounds based on 5-(pyridin-3-yl)isophthalate ligands bearing different substituents were rationally constructed. As revealed by isotherm measurements, thermodynamic studies, and IAST computations, they exhibited promising utility for C2H6/C2H4 separation with moderate adsorption heat and a high uptake amount at a relatively low-pressure domain. Furthermore, the C2H6/C2H4 separation potential can be finely tuned and optimized via purposeful substituent alteration. Most remarkably, functionalization with a nonpolar methyl group yielded an improved separation efficiency compared to its parent compound. This work offers a good reference value for enhancing the C2H6/C2H4 separation efficiency of MOFs by engineering the pore microenvironment and dimensions via substituent manipulation.

Abstract
Implementation of lanthanide-organic frameworks (LOFs) as solid adsorbents has been frequently handicapped by their permanent porosity being difficult to establish owing to the remarkable flexibility and diversity of lanthanide ions in terms of coordination number and geometry. Construction of robust LOFs with permanent porosity for industrially important hydrocarbon separation will greatly expand their application potential. In this work, by distributing N and O donors into an m-terphenyl skeleton, we rationally synthesized a heterofunctional linker, and constructed a pair of isostructural LOFs. Due to the inclusion of a rarely observed three-dimensional metal-carboxylate backbone serving as a highly connected inorganic secondary building unit, their permanent porosities were successfully established by diverse gas isotherms. They can be applied as separating media not only for natural gas purification and removal of carbon dioxide from C2 hydrocarbons but also more importantly for single-step ethylene (C2H4) purification from a three-component C2Hn mixture during the adsorption process. The latter separation is very challenging and has been less reported in the literature. This work provides a unique example of LOFs featuring three-dimensional inorganic connectivity applied to multipurpose hydrocarbon separations.

Abstract
Natural gas (NG) and ethylene (C2H4) are two raw materials of significant value for manufacturing versatile fine chemicals and/or polymers, and thus the development of solid adsorbing agents such as metal-organic frameworks (MOFs) applied to their depuration is very crucial but remains highly challenging. In this research, we designed and synthesized a ligand containing mixed N and O coordination donors, which was solvothermally assembled with Cu(II) ions to generate a microporous MOF. X-ray crystallography revealed that the title MOF incorporates one-dimensional (1D) homochiral helical chains that are datively cross-linked to form open channels in the three-periodic coordination framework. Furthermore, the behaviors of C1-C2 hydrocarbons and carbon dioxide (CO2) adsorbed in the title MOF were systematically investigated, revealing its promising potential for the purification of both NG and C2H4. At 109 kPa and 298 K, the C2/methane (CH4), CO2/CH4, and acetylene (C2H2)/C2H4 adsorption selectivities are impressive, reaching as high as 62.9, 28.6, and 3.5, respectively. This work represents a unique MOF based on cross-linked homochiral helical chains exhibiting dual-function separation potentials for NG and C2H4 purifications.

Abstract
To enrich structural chemistry and widen the application prospects of MOFs (metal-organic frameworks), the development of a synthetic strategy to realize structural and functional modulation is highly demanded. By implementation of the linker bent-angle engineering strategy, three banana-like diisophthalate linkers with distinct bent angles were designed and synthesized. The inclusion of the targeted linkers into MOFs through solvothermal assembly with CuCl2·2H2O under identical conditions yielded three crystalline solids featuring diversified topological structures as revealed by X-ray crystallographic studies. Furthermore, functional explorations indicated that they are promising solid adsorbents for acetylene (C2H2) purification application with structurally dependent separation potentials. The results reported in this study illustrated a rare example of modulating the topological structures and separation efficiencies of MOFs by engineering the ligand bent angles.

Abstract
The development of porous materials for ethylene (C2H4) separation and purification, a very important separation process in the chemical industry, is urgently needed but quite challenging. In particular, the realization of selectivity-reversed adsorption (namely, C2H4 is not preferentially adsorbed) and the simultaneous capture of multinary coexisting impurities such as ethane (C2H6) and acetylene (C2H2) will significantly simplify process design and reduce energy and cost consumption, but such porous materials are quite difficult to design and have not yet been fully explored. In this work, by employing an aromatic-rich bithiophene-based tetraisophthalate ligand, we solvothermally fabricated an anionic In(III)-based framework termed ZJNU-115 featuring In(COO)4 as an inorganic secondary building unit as well as one-dimensional channels. Due to the absence of unsaturated metallic sites, together with aromatic-rich channel surface decorated with abundant hydrogen-bonding acceptors of carboxylate oxygen and thiophene sulfur atoms, desolvated ZJNU-115 exhibited an unusual adsorption relationship with respect to C2 hydrocarbons, namely, simultaneous and preferable capture of C2H6 and C2H2 over C2H4 at the temperatures investigated, thus representing a rare metal-organic framework (MOF) with the promising potential for one-step adsorption-phase purification of C2H4 from a trinary C2 hydrocarbon mixture. Compared to a few of the MOFs reported for such an application, ZJNU-115 displayed simultaneously good adsorption selectivities of both C2H2 and C2H6 over C2H4. Furthermore, its separation potential can be postsynthetically tailored by substituting dimethylammonium (Me2NH2+) counterions with tetraalkyl ammonium ions (NR4+; R = Me, Et, or n-Pr). More importantly, ZJNU-115 was stable in various organic solvents as well as aqueous solutions with pH values ranging from 5 to 9, thus laying a solid foundation for its practical applications. The design principle and the performance regulation strategy adopted in this work will offer valuable guidance for the contrapuntal construction of porous MOFs employed for direct multicomponent purification of C2H4 with improved performance.

Abstract
To push forward the structural development and fully explore the potential utility, it is highly desired but challenging to regulate in a controllable manner the structures and properties of MOFs. In this work, we reported the structural and functional modulation of Cu(II)-tricarboxylate frameworks by employing a strategy of engineering the functionalities and their positions. Two pairs of unsymmetrical biaryl tricarboxylate ligands modified with a methyl group and a pyridinic-N atom at distinct positions were logically designed and synthesized, and their corresponding Cu(II)-based MOFs were solvothermally constructed. Diffraction analyses revealed that the variation of functionalities and their positions furnished three different types of topological structures, which we ascribed to the steric effect exerted by the methyl group and the chelating effect involving the pyridinic-N atom. Furthermore, gas adsorption studies showed that three of them are potential candidates as solid separation media for acetylene (C2H2) purification, with the separation potential tailorable by altering functionalities and their locations. At 106.7 kPa and 298 K, the C2H2 uptake capacity varies from 64.1 to 132.4 cm3 (STP) g-1, while the adsorption selectivities of C2H2 over its coexisting components of CO2 and CH4 fall in the ranges of 3.28-4.60 and 14.1-21.9, respectively.

Abstract
Maturity degree and quality evaluation are important for strawberry harvest, trade, and consumption. Deep learning has been an efficient artificial intelligence tool for food and agro-products. Hyperspectral imaging coupled with deep learning was applied to determine the maturity degree and soluble solids content (SSC) of strawberries with four maturity degrees. Hyperspectral image of each strawberry was obtained and preprocessed, and the spectra were extracted from the images. One-dimension residual neural network (1D ResNet) and three-dimension (3D) ResNet were built using 1D spectra and 3D hyperspectral image as inputs for maturity degree evaluation. Good performances were obtained for maturity identification, with the classification accuracy over 84% for both 1D ResNet and 3D ResNet. The corresponding saliency maps showed that the pigments related wavelengths and image regions contributed more to the maturity identification. For SSC determination, 1D ResNet model was also built, with the determination of coefficient (R 2) over 0.55 of the training, validation, and testing sets. The saliency maps of 1D ResNet for the SSC determination were also explored. The overall results showed that deep learning could be used to identify strawberry maturity degree and determine SSC. More efforts were needed to explore the use of 3D deep learning methods for the SSC determination. The close results of 1D ResNet and 3D ResNet for classification indicated that more samples might be used to improve the performances of 3D ResNet. The results in this study would help to develop 1D and 3D deep learning models for fruit quality inspection and other researches using hyperspectral imaging, providing efficient analysis approaches of fruit quality inspection using hyperspectral imaging.

Abstract
To expand the structural diversity and optimize the material performance, it is essential but challenging to regulate MOF structures in a predictable and controllable manner. In this work, by manipulating the substituents to engineer the ligand conformations, we designed and synthesized two asymmetric tricarboxylate ligands, and used them to successfully target two copper-tricarboxylate frameworks with diversified topologies depending on the ligand conformations. Besides, the ligand asymmetry induced the formation of two uncommon kinds of copper-carboxylate clusters, thus greatly expanding the library of copper-carboxylate secondary building units. Furthermore, the two compounds also displayed tunable gas adsorption properties pertinent to C2H2 separation and purification. At 298 K and 1 atm, the uptake capacity of C2H2 varies from 79.5 to 104.6 cm3 (STP) g-1, while the adsorption selectivities of C2H2 with respect to CO2 and CH4 are in the range of 2.3-3.8 and 15.3-21.6 for the equimolar components, respectively. Compared to the nitro counterpart, the methoxy MOF features higher C2H2 uptake capacity, larger C2H2/CO2 and C2H2/CH4 adsorption selectivities, and lower regeneration energy. This work demonstrates that simple ligand modification can be used to engineer the structures and tune gas adsorption properties of the resulting MOFs.

Abstract
Design and construction of stable adsorbents for efficient separation and purification of natural gas and C2H2 is fundamentally important in the chemical industry, and hierarchical cage-based MOFs are attractive in this regard due to their intrinsic structural advantages. In this work, a cage-based MOF (termed ZJNU-15) assembled from a tetranuclear Cu4O-based SBU and an amine-functionalized N,O-mixed donor ligand was solvothermally constructed. Single-crystal X-ray diffraction studies showed that the resulting MOF incorporates two different types of polyhedral cages in the entire network and bears incompatible open copper sites and uncoordinated amine groups immobilized in the pore surface. In view of its intriguing structural features, its gas adsorption properties with respect to C2 hydrocarbons, CO2, and CH4 were systematically investigated, revealing that it could achieve efficient removal of C2 hydrocarbons and CO2 from CH4 as well as separation of a binary C2H2-CO2 mixed gas, which is associated with natural gas and C2H2 separation and purification. At 298 K and 1 atm, for equimolar binary components, the IAST-predicted adsorption selectivities for C2 hydrocarbons over CH4 are above 17.7, while the CO2/CH4 and C2H2/CO2 adsorption selectivities are 5.0 and 4.4, respectively. Notably, stability studies showed that the framework maintained its structural integrity after being immersed in HCl/NaOH aqueous solutions within a pH range of 4-11 at ambient temperature for 24 h, indicating its good hydrolytic stability under harsh chemical conditions, which might lay a solid foundation for its practical applications.

Abstract
The Cu-doped ZnAl layered double hydroxides (LDH) were papered by coprecipitation. The prepared samples were characterized by mutiple techniques including X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET) surface area, scanning electronic microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and UV-vis diffuse-reflectance spectroscopy (UV-vis DRS). The doping of Cu2+ into the LDH sheets results in formation of the distorted CuO6 octahedrons which contribute for the excitation of electrons under visible light. The doped Cu2+ also serves as photo-generated charges separator and improves the visible-light-driven photocatalytic activity of ZnAl LDH. A degradation mechanism based on the hydroxyl radical as the active species was proposed.

Abstract
OBJECTIVES To study the case characteristics of forensic medical identification of traumatic tympanic membrane perforations, and to discuss the key points of forensic medical identification and evaluations methods for tympanic membrane perforations. METHODS Twenty-four cases of traumatic tympanic membrane perforations accepted by the Academy of Forensic Science during 2017 were retrospectively analysed. The data of perforation size, form, predilection site, healing time and healing mode were evaluated. RESULTS For the traumatic tympanic membrane perforations, the study showed that the small size of perforation (<1/2 quadrant) with irregular shape was common. The location of perforations was almost on the anterior and inferior quadrant, and centripetal migration healing was common. The healing rate within 6 weeks was up to 90%. CONCLUSIONS In the identification cases of traumatic tympanic membrane perforations, the key is to determine whether it is traumatic and whether it will heal spontaneously within 6 weeks. It is suggested to check the tympanic membrane weekly by an otic endoscope combined with acoustic impedance measurement at the sixth week, which can improve the accuracy, objectivity and scientificity of the identification.

Abstract
The lower extremity impairment can be caused by illness, accident, work-related injury, traffic accident and fighting, etc. The injuries of lower extremity joint, nerve, muscle and tendon may lead to lower extremity dysfunction. So far, there is no unified standard for international and domestic function evaluation of lower extremity impairment, the evaluation standards in the same field are also different, and function evaluation of lower extremity impairment has no complete research system. However, the degree of lower extremity impairment has great influence on personal damage compensation. Therefore, the function evaluation of lower extremity impairment often becomes a dispute issue in forensic medicine identification. This article summarizes the function evaluation standards, methods and status quo of lower extremity impairment, so as to provide a new insight into the research on standardization of lower extremity impairment.

Abstract
NiZnAl layered double hydroxides (LDH) with Ni/Zn/Al ratios ranging from 0.1/2/1 to 1/2/1 were papered by coprecipitation. The prepared samples were characterized by multiple techniques including X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET) surface area, scanning electronic microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and UV-vis diffuse-reflectance spectroscopy (UV-vis DRS). The incorporation of Ni2+ into the brucite sheets preserves the layered structure of ZnAl LDH. The doped Ni2+ serves as the photogenerated charges separator and improves the visible light photocatalytic activity of ZnAl LDH at a reasonable content. A degradation mechanism based on the hydroxyl radical as the active species was proposed.

Abstract
Olfaction is one of the basic feelings, which plays an important role in appetite, warning of danger and emotion regulation, etc. More and more studies have shown that olfactory dysfunction may affect quality of human life. Thus, the attention of olfactory dysfunction is increasing. There are many subjective and objective methods for olfactory function detection, and olfactory event-related potential (OERP) is a more objective method. This article reviews the development, testing and analysing methods and clinical research of OERP, and explores its application prospects in forensic clinical medicine.

Abstract
Acute Stanford type A aortic dissection with important branches involved is more complex, could lead to organ malperfusion syndrome even organ failure. The understanding of pathological anatomy, classification, staging, and the pathophysiological change has increasingly mature, but not complete. In addition, the treatment strategy for complex lesions is diversified, some questions may not reach consensus. Fully understanding of the anatomical and pathophysiology is very important for surgeons to choose reasonable treatment strategy. As the rapid development of the basic research, imaging techniques and the concept of surgery procedures, the manage technique of Stanfrod type A dissection and branch vessels at the same time is getting seriously, the related issues also need further discussions.

Abstract
Ischemic stroke can lead to loss of neurologic functions. It occurs due to obstruction in blood supply to the brain. It has been proposed that C807T(C/T) polymorphism within the platelet glycoprotein gene may be associated with density and function of glycoprotein Ia/IIa receptors and contributes to the pathogenesis of thrombotic disease. We assessed the association between C807T(C/T) and risk of ischemic stroke. Databases such as PubMed, Medline, Springer, Elsevier Science Direct, Cochrane Library, Google scholar, Wanfang Data (Chinese), and Chinese National Knowledge Infrastructure (CNKI, Chinese) were used to search for relevant studies. We found 16 eligible studies, which totaled to 4897 (case group 2340; control group 2557) participants. Overall, our results showed significant associations between C807T(C/T) polymorphism and risk of ischemic stroke based on T-allele comparisons (T vs C, pooled OR = 0.78, 95%CI = 0.68-0.90, P < 0.01), TT vs CC comparisons (pooled OR = 0.58, 95%CI = 0.42-0.81, P < 0.01), recessive models (TT vs TC + CC, pooled OR = 0.72, 95%CI = 0.59-0.87, P < 0.01) and dominant models (TT + TC vs CC, pooled OR = 0.70, 95%CI = 0.54-0.92, P < 0.05). There was no association in TC vs CC comparisons (pooled OR = 0.81, 95%CI = 0.63-1.04, P > 0.05). Subgroup analyses stratified according to Hardy-Weinberg equilibrium, sample size, and ethnicity also demonstrated significant associations between the two variables. Therefore, C807T(C/T) polymorphism in the platelet glycoprotein gene may be associated with susceptibility to ischemic stroke, and the T allele at this locus may decrease risk to ischemic stroke.

Abstract
OBJECTIVES To study the characteristics of the relationship between injury and disease in forensic identification cases of cervical trauma with cervical vertebra degeneration, and to explore the problems about how to identify the participation rates of injury and disease using the clinical information, forensic examination and imaging examination. METHODS Seventeen forensic identification cases of cervical trauma with cervical vertebra degeneration were collected. The age distributions, injury formations, injury severities and imaging findings of these cases were analyzed and the relationship between injury and disease was evaluated comprehensively. RESULTS Middle-aged and elderly were common in 17 cases and every case was involved with intervertebral disc herniation. The main reasons of injuries were hyperextension. The degree of injury severity and vertebra degeneration were graded according to the imaging findings. The participation rates of injury and disease were also calculated comprehensively. CONCLUSIONS The forensic identification cases of cervical trauma with cervical vertebra degeneration should be evaluated with clinical information, forensic examination and imaging finding.

Abstract
Autogenous arteriovenous fistula (AVF) is the first choice for hemodialysis access in renal failure with uremia. However, AVF cannot be performed in some patients due to small and narrow veins in the forearm. In this study, a Fogarty catheter was used to establish autogenous radiocephalic hemodialysis access in patients with small caliber cephalic veins, and the patency rate and complications of this method were observed. Sixty-seven patients with uremia were divided into a treatment group (40 cases, caliber of cephalic veins<2.5 mm) and a control group (27 cases, caliber of cephalic veins≥2.5 mm). According to ultrasound results, the treatment group received AVF after expansion with a Fogarty catheter, and the control group received traditional AVF. The fistula patency rate and complications were observed during follow-up. All patients were followed up for an average period of 18 months (range=3-36 months). AVF was successfully used in 58 patients for hemodialysis, with primary access failure in 9 cases (5 cases in the treatment group and 4 cases in the control group) due to early thrombosis. The primary and secondary patency rates 12 months after surgery in the treatment group were 64 and 72%, respectively, and those in the control group were 60 and 76%, respectively. Patients with small caliber cephalic veins can be treated with radiocephalic fistula after the caliber of cephalic veins is expanded to more than 2.5 mm with a Fogarty catheter. The long-term patency rate awaits observation in a longer follow-up period.

Abstract
We examined microRNA-181b (miRNA) expression in prostate cancer tissues and its effect on the prostate cancer cell line PC-3. Tissues from 27 cases of prostate cancer and 30 samples of normal human prostate were collected by surgical removal. Total miRNA was extracted, and the relative expression of miR-181b was quantified using RT-PCR. miR-181b ASO was transfected into prostate cancer PC-3 cells. miR-181b expression in transfected and non-transfected cells was measured using RT-PCR. Changes in cell apoptosis were measured using flow cytometry. MTT and cell growth curve methods were used to assess the influence of miR-181b expression on cell proliferation. The changes in cell invasive ability in vitro were detected using the Transwell chamber method. miR-181b was up-regulated in the prostate cancer tissues compared with the normal prostate samples. It was down-regulated after miR-181b ASO transfection into the prostate cancer PC-3 cells. Down-regulation of miR-181b in the PC-3 cell induced apoptosis, inhibited proliferation, and depressed invasion of PC-3 cells in vitro. As miR-181b is over-expressed in prostate cancer, its down-regulation could have potential as gene therapy for prostate cancer by inducing apoptosis, inhibiting proliferation and depressing invasion by cancer cells.

Abstract
OBJECTIVE To explore the relationship between XRCC3 and lung cancer after selecting tag SNPs from HapMap database and reconstructing haplotypes. METHODS Using case-control study design, smoking condition were surveyed by questionare. Peripheral blood of cases and saliva or buccal cell for controls were collected, and then their DNA were extracted. XRCC3 tagSNPs were genotyped by PCR-RFLP. TagSNPs were selected by Haploview, HWE and LD were checked by LDA. Best genetic model and relationship between tagSNPs and lung cancer were analysed by SPSS, and haplotype frequencies and effects were computed by THESIAS. RESULTS Carriers of rs861537 AG or AA genotype had a statistically significantly increased risk for lung cancer (OR = 1.48, 95% CI: 1.17-1.86). Carriers of rs1799794 per G allele had a statistically significantly decreased risk for lung cancer (OR = 0.83, 95% CI: 0.72-0.97); no significant association was observed between rs861539 and lung cancer. Smoke interacted with rs861537 polymorphism. Compared with CGG haplotype, carriers of CAA had a statistically significantly increased risk for lung cancer (OR = 1.32, 95% CI 1.11-1.57). CONCLUSION XRCC3 gene polymorphisms were associated with lung cancer.

Abstract
OBJECTIVE To study the association between DNA double-strand break repair gene NBS1 (nijmegen breakage syndrome gene) polymorphisms and the susceptibility to lung cancer. METHODS A case-control study design was applied. PCR-RFLP was used to identify NBS1 polymorphisms among 575 lung cancer cases and 575 controls. RESULTS The frequencies of C/C, C/G and G/G genotypes at NBS1 rs1805794 site were 25.9%, 51.8%, 22.3% among controls compared to 20.5%, 52.3%, 27.1% among cases. There was significant difference between controls and cases (χ(2) = 6.38, P = 0.04). Individuals carrying C/G + G/G genotypes had an increased risk for lung cancer (OR = 1.46, 95%CI: 1.09 - 1.97) compared to the C/C genotype. The frequencies of G/G, G/C and C/C genotypes at NBS1 rs2735383 site were 37.9%, 47.0%, 15.1% among controls compared to 35.5%, 48.5%, 16.0% among cases, with no significant difference between the two groups (χ(2) = 0.75, P = 0.69). Individuals carrying Hap4-GC haplotype (OR = 1.70, 95%CI: 1.24 - 2.31) and Hap4/Hap2 dihaplotype (OR = 1.75, 95%CI: 1.11 - 2.76) had an increased risk on lung cancer. Joint associations of smoking and the NBS1 polymorphism with the risk of lung cancer were observed (P < 0.05). CONCLUSION The G/G genotype at NBS1 rs1805794 site and the Hap4-GC haplotype and Hap4/Hap2 di haplotype from rs1805794 and rs2735383 were both associated with lung cancer.

Abstract
Five analogues of 3-quinuclidinyl benzilate were prepared in which one phenyl ring was substituted by a heterocycle; a bromine was included on either the remaining phenyl or the heterocycle to provide information relating to the affinity of potential radiohalogenated derivatives. Their affinities for the muscarinic cholinergic receptor were determined. Replacing a phenyl ring with either the 2- or 3-furyl moiety or the 2- or 3-thienyl moiety did not significantly alter the affinity to the muscarinic receptor compared with 3-quinuclidinyl 4-bromobenzilate.

Abstract
Seven analogues of 3-quinuclidinyl benzilate (QNB) in which one phenyl ring was replaced by an alkoxyalkyl moiety were synthesized and their affinities for the muscarinic cholinergic receptor determined. An oxygen in the beta-position of the moiety was not well-tolerated. By contrast, an oxygen in the gamma-position did not change the affinity for the muscarinic receptor. However, when a bromine was placed on the remaining phenyl ring, the affinity was significantly reduced in striking contrast to results obtained on halogenation of QNB.

Abstract
T-lymphocytes form the peripheral blood of 12 patients with aplastic anemia (AA) and 4 patients with aplastic anaemia-paroxysmal hemoglobinuria syndrome (AA-PNH) were cultivated and their subsets were measured by monoclonal antibodies CD4, CD8, CD25 with indirect immunofluorescence technique. Change of the proportion of T-lymphocyte subsets was observed in 5 patients with AA after the mononuclear cells were activated with phytohemagglutinin (PHA). Its was shown that the number of CFU-T of the patients with AA was apparently decreased in comparison with that of normal controls (P less than 0.05). Disorder of T-lymphocyte subsets took place in patients with AA. The percentages of CD8 and CD25 lymphocytes were increased. The helper: suppressor T-lymphocytes (CD4:CD8) ratio was significantly increased (P less than 0.01). In the cases of AA-PNH, the number of CFU-T was significantly increased (P less than 0.01) and that of T-lymphocyte subsets did not change. The ratio of CD4/CD8 in 5 patients with AA was further decreased after activating mononuclear cells with PHA. These results showed that the increase of T-lymphocytes in patients with AA may account for the low level of CFU-T; the high level of CFU-T in patients with AA-PNH may be related to the multiplication of bone marrow cells. However, there may be a potential disorder of immune system on patients with AA at the same time.

Abstract
rac-4-Nitrobenzilic acid was synthesized and resolved with quinidine and quinine to give the corresponding (R)- and (S)-salts. The resolved diastereomeric salts were converted to (R)- and (S)-4-nitrobenzilic acids and subsequent esterification gave their corresponding ethyl esters. Transesterification with (R)-(-)-3-quinuclidinol afforded (R)-(-)-1-azabicyclo[2.2.2]oct-3-yl-(R)-(+)-alpha-hydroxy-alpha- (4-nitrophenyl)-alpha-phenyl acetate and (R)-(-)-1-azabicyclo[2.2.2]oct-3-yl-(S)-(-)-alpha-hydroxy- alpha-(4-nitrophenyl)-alpha-phenyl acetate. After hydrogenation, the (R,R)- and (R,S)-amines were converted to the respective triazene derivatives. The triazene derivatives reacted with sodium [125I]iodide to give (R)-(-)-1-azabicyclo[2.2.2]oct-3-yl-(R)-(+)- alpha-hydroxy-alpha-(4-[125I]iodophenyl)-alpha-phenyl acetate and (R)-(-)-1-azabicyclo[2.2.2]oct-3-yl-(S)-(-)-alpha-hydroxy- alpha-(4-[125I]iodophenyl)-alpha-phenyl acetate. The evaluation of their affinities to muscarinic acetylcholine receptors (MAcChR) shows that (R)-(-)-1-azabicyclo[2.2.2]oct-3-yl-(S)-(-)-alpha-hydroxy-alpha-(4- [125I]iodophenyl)-alpha-phenyl acetate exhibits an affinity for the MAcChR from corpus striatum that is approximately threefold lower than that of (R)-(-)-1-azabicyclo[2.2.2]oct-3-yl-(R)-(+)-alpha-hydroxy-alpha-(4- [125I]iodophenyl)-alpha-phenyl acetate.
