Abstract
Red blood cells (RBCs) are biocompatible carriers that can be employed to deliver different bioactive substances. In the past few decades, many strategies have been developed to encapsulate or attach drugs to RBCs. Osmotic-based encapsulation methods have been industrialized recently, and some encapsulated RBC formulations have reached the clinical stage for treating tumors and neurological diseases. Inspired by the intrinsic properties of intact RBCs, some advanced delivery strategies have also been proposed. These delivery systems combine RBCs with other novel systems to further exploit and expand the application of RBCs. This review summarizes the clinical progress of drugs encapsulated into intact RBCs, focusing on the loading and clinical trials. It also introduces the latest advanced research based on developing prospects and limitations of intact RBCs drug delivery system (DDS), hoping to provide a reference for related research fields and further application potential of intact RBCs based drug delivery system.

Abstract
Objective: To investigate the interference of daratumumab on immunofixation electrophoresis after treating plasma cell diseases and methods to eliminate the interference. Methods: Serum samples of eight patients with plasma cell diseases treated with daratumumab in Peking University People's Hospital from April 2020 to March 2021 were collected for standard immunofixation electrophoresis and Hydrashift 2/4 daratumumab assay. Results: After treatment, 81.3% (13/16) of the samples showed drug-induced monoclonal antibodies (IgG-κ) . The samples without drug-induced monoclonal bands were related to individual differences, administration intervals, and immunoglobulin levels. Among the samples with IgG-κ monoclonal bands, 76.9% (10/13) could be directly identified as endogenous or exogenous monoclonal bands by immunofixation electrophoresis, and the others (3/13) could be identified by Hydrashift 2/4 daratumumab assay. Conclusion: Hydrashift 2/4 daratumumab assay can remove the band of daratumumab on the immunofixation electrophoresis and help with efficacy evaluation.

Abstract
Objective: To investigate the clinical value of p16/Ki-67 immunocytochemistry in patients with atypical squamous cells of undetermined significance(ASC-US). Methods: One hundred and seventy-one cases of thin-prep cytology test (TCT) diagnosed as ASC-US underwent p16/Ki-67 immunocytochemistry. All patients had colposcopy and biopsy from March 2015 to January 2016. Ninety of the 171 cases underwent high-risk HPV test at the same time. Results: p16/Ki-67 immunocytochemistry was positive in 43.9% (75/171) of the 171 cytology samples; the sensitivity and specificity of p16/Ki-67 immunocytochemistry were 77.6%(52/67) and 77.9%(81/104) in detecting CIN2+ , and the positive and negative predictive value were 69.3%(52/75) and 84.4%(81/96), respectively. The sensitivity and specificity in diagnosing CIN2+ were 100.0%(34/34) and 10.7%(6/56) for HPV test, and the positive and negative predictive value were 40.5%(34/84) and 6/6. p16/Ki-67 immunocytochemistry showed lower sensitivity but obviously higher specificity than high-risk HPV detection. Conclusion: p16/Ki-67 immunocytochemistry is a good triage test for identifying CIN2+ in ASC-US specimens.

Abstract
OBJECTIVE To evaluate the clinical value of thyroid fine needle aspiration cytology(FNAC) and the Bethesda system for reporting thyroid cytopathology(TBSRTC). METHODS FNAC was performed for 2 043 cases and cytopathological data were retrospectively analyzed. Cytopathological diagnoses according to TBSRTC were classified as non-diagnostic, benign, atypia of undetermined significance/follicular lesion of undetermined significance(AUS/FLUS), follicular neoplasm/suspicious for follicular neoplasm(FN/SFN), suspicious for malignancy(SM) and malignancy. The results of 234 FNAC samples in which surgery was performed were compared with the histological diagnoses. RESULTS Of the 2 043 FNAC samples, 15.7%(320/2 043)were non-diagnostic, 51.2%(1 047/2 043)were benign, 16.6%(339/2 043) were AUS/FLUS, 2.3%(46/2 043)were FN/SFN, 8.6%(176/2 043)were SM and 5.6%(115/2 043)were malignant. In 234 cases, there was follow-up histology. Rates of malignancy were as follows: non-diagnostic, 18.2%(2/11); benign(2.2%, 1/45); AUS/FLUS(25.6%, 10/29); FN/SFN(12.1%, 10/39); SM(91.8%, 56/61); malignant(100.0%, 45/45). The sensitivity, specificity, false positive rate, false negative rate and overall accuracy of FNAC in the diagnosis of thyroid nodules was 87.1%(101/116), 95.3%(102/107), 4.7%(5/107), 12.9%(15/116), 91.0%(203/223). CONCLUSIONS FNAC is a reliable diagnostic method for evaluation of thyroid disease. TBSRTC is a accurate and effective reporting system for cytopathological diagnoses, so it is worthy of being widely popularized in clinical application.

Abstract
PURPOSE The aim of this study was to investigate the cost-effectiveness of laparoscopic treatment for ectopic pregnancy by comparing the medical expenses and time of hospitalization of laparoscopic and open surgery for ectopic pregnancy in partial area of Shanghai, China. MATERIALS AND METHODS Clinical data of 762 cases with ectopic pregnancy undergoing surgical treatment (307 cases for laparoscopic surgery and 455 cases for open surgery) were analyzed retrospectively. The clinical information including the medical expenses and time of hospitalization was compared. The patients were divided into three groups according to the treatments of different lesions (lesions resection, conservative laparotomy, and exploration group) and were analyzed. RESULTS The total hospitalization expenses and the top three single costs including surgery, exams, and medicine expenses were higher in laparoscopic group than in open surgery group. There was no significant difference between the two groups on the total time of hospitalization. The hospital days of preoperation were higher but the postoperative hospital days were lower in laparoscopic group than in open surgery group. Compared with the open surgery treatment, the hospitalization expenses of laparoscopic treatment for ectopic pregnancy increased. There was no significant difference on the total hospitalization days. CONCLUSION The preoperative waiting period of inpatients increased and the post-operative hospital days reduced in laparoscopic group.

Abstract
BACKGROUND Sirolimus-based regimens have recently been introduced as nephron-sparing strategies to avoid the calcineurin inhibitors-induced nephrotoxicity. METHODS To investigate the different effects of these 2 immunosuppressants on CD4(+)CD25(hi)FoxP3(+) regulatory T cells (Tregs) and the newly defined subsets of FoxP3(+) T cells, including CD45RA(-)FoxP3(lo) cytokine-secreting T cells (csT cells), CD45RA(-)FoxP3(hi) activated Treg (aTregs), and CD45RA(+)FoxP3(+) resting Treg (rTregs), 52 cases of renal transplant recipients who have received a maintenance immunosuppressive regimen comprised either cyclosporine (n = 34) or sirolimus (n = 18) were collected and proportion of Tregs and each subset of FoxP3(+) T cells in peripheral blood was detected by flowcytometry. RESULTS Sirolimus significantly prompted the proportion of Tregs (5.92 ± 0.40 vs 2.19 ± 0.18; P < .001) and both of the CD45RA-negative subsets, including csT cells (4.92 ± 0.50 vs 1.83 ± 0.18; P < .001) and aTregs (1.04 ± 0.15 vs 0.23 ± 0.05; P < .05) when compared with cyclosporine. However, the rTregs were not remarkably affected (0.36 ± 0.09 vs 0.79 ± 0.28; P = .063). CONCLUSION Sirolimus plays its immune regulatory role in renal transplantation partly by increasing the proportion of Tregs. However, the increasing of both pro- and anti-inflammatory subsets of FoxP3(+) T cells also indicates the potential compromising of the effects of sirolimus on immune regulation.

Abstract
BACKGROUND Soluble fibrinogen-like protein 2 (sfgl2), which is mainly secreted by T cells, is a novel effector of regulatory T cells with immunosuppressive functions. The aim of this study was to investigate serum levels of sfgl2 among renal allograft recipients. METHODS From November 2010 to August 2011 we retrospectively divided 47 renal allograft recipients into an acute rejection (n = 19) versus a stable group (n = 28) according to allograft biopsy results, using the Banff 2007 classification. The acute rejection group was subdivided into grade I (n = 8) versus grade II T-cell-mediated (n = 6) or antibody-mediated rejection episodes (n = 5). Peripheral blood samples were collected at the time of biopsy. Fourteen healthy volunteers were included as normal group controls. Serum levels of sfgl2 were analyzed by enzyme-linked immunosorbent assay. RESULTS Serum levels of sfgl2 were increased among renal allograft recipients suffering from biopsy-proven acute rejection episodes (61.91 ± 45.68 ng/mL), versus those with stable allografts (38.59 ± 19.92 ng/mL, P < .05) or healthy volunteers (29.10 ± 18.08 ng/mL, P < .05). The sfgl2 level was significantly higher among patients with antibody-mediated (118.48 ± 55.54 ng/mL) than T-cell-mediated acute rejection episodes (41.71 ± 16.44 ng/mL, P < .01). Serum sfgl2 levels were remarkably elevated in patients with grade II (51.87 ± 19.13 ng/mL) versus grade I T-cell-mediated rejection (34.10 ± 9.26 ng/mL, P < .05). CONCLUSIONS Serum sfgl2 levels were increased among renal allograft recipients with acute rejection episodes to an extent dependent upon the pathological type and severity of the response.

Abstract
Acute tubular injury (ATI) is very common in biopsy specimens from renal allografts that suffer from delayed graft function (DGF) or dysfunction. Currently there are few reports on investigating small molecule metabolites in urine samples from transplant recipients as a noninvasive method to predict the ATI of renal allografts instead of an allograft biopsy. In our study matrix-assisted laser desorption/ionization Fourier transform mass spectrometry (MALDI-FTMS) was used to analyze small molecule metabolites in urine samples from renal transplant recipients with biopsy-proven slight ATI or moderate ATI or acute tubular necrosis (ATN). To evaluate the ATI-specific value of those small molecules, we applied the Principal Component Analysis (PCA) program. Mass spectra data were imported into the PCA, where loading graphs were constructed to express the constituents of the urine samples. Slight ATI, moderate ATI, or ATN of renal allografts were separated obviously in the loading graph. The position of urine samples in the graph may reflect the tubular injury status of allografts. A farther apart point from the original site may mean the allograft suffered from more severe ATI (even ATN), and vice versa. Detection of small molecule metabolites in urine samples of recipients through MALDI-FTMS may offer a promising noninvasive, high throughput, rapid tool to predict ATI/ATN of renal allografts.

Abstract
RASSF1A (RAS-association domain family 1, isoform A) is a newer tumor suppressor that binds to and stabilizes microtubules as well as induces M-phase cell cycle arrest. Several other proteins that interact with and stabilize microtubules also undergo mitotic phase phosphorylation to regulate microtubule dynamics and M-phase cell cycle progression. Currently, however, there is a paucity of information regarding the phosphorylation status of RASSF1A and its regulation during mitosis. In this study, for the first time, we demonstrate that Aurora-A is a RASSF1A kinase and, to the best of our knowledge, this is also the first study reporting the identification of a kinase for RASSF1A. We show that the mitotic kinase Aurora-A directly interacts with and phosphorylates RASSF1 and that RASSF1A is phosphorylated by Aurora-A during mitosis. These findings therefore link an important oncogenic mitotic kinase to regulate RASSF1A tumor suppressor. Aurora-A appears to phosphorylate RASSF1A at Threonine202 and/or Serine203 that reside within the known microtubule-binding domain of RASSF1A. Substitutions of these residues with glutamic acid at both positions, mimicking constitutive phosphorylation of RASSF1A, disrupt RASSF1A interactions with microtubules and abolish its ability to induce M-phase cell cycle arrest. Our results further demonstrate that Aurora-A overexpression also interferes with RASSF1A-mediated growth suppression. In view of our results, we propose that Aurora-A-mediated phosphorylation of RASSF1A is a novel mechanism that regulates the ability of this tumor suppressor to interact with microtubules and modulate M-phase cell cycle progression.

Abstract
A rapid, sensitive and specific liquid chromatography-electrospray ionization mass spectrometric (LC-ESI-MS) method has been developed for the quantification of trimetazidine in human plasma. The analyte and the internal standard (pseudoephedrine) were extracted from plasma samples with n-hexane-dichloromethane (1:1, v/v) and analyzed on a C18 column. The chromatographic separation was achieved within 3.5 min using the mobile phase consisting of methanol/0.05% formic acid (80:20, v/v) and the flow rate was 1.0 ml/min. Ion signals m/z 181.0 and 148.0 were measured in the positive mode for trimetazidine and pseudoephedrine, respectively. The calibration curves were linear within the range of 0.4 to approximately 120 ng/ml. The lower limit of quantification (LLOQ) was 0.4 ng/ml with 0.5 ml plasma sample. The intra- and inter-day precisions were lower than 12% in terms of relative standard deviation (RSD). The inter-day relative error (RE) as determined from quality control samples (QCs), ranged from -1.4% to 3.3%. This validated method was successfully applied to the bioequivalent evaluation of two brands of trimetazidine tablets in 20 healthy volunteers.

Abstract
AIMS/HYPOTHESIS Polymorphisms of the gene encoding adiponectin (ADIPOQ) have previously been associated with type 2 diabetes in Europid and Japanese subjects, but not in Pima Indians. The aim of this study was to determine the contribution made by ADIPOQ gene variants to glycaemic status in southern Chinese individuals. SUBJECTS AND METHODS Sixty unrelated subjects were screened for single-nucleotide polymorphisms (SNPs) in the ADIPOQ gene by direct sequencing. The association of tagging SNPs with the outcome of glycaemic status in 262 subjects with impaired glucose tolerance (IGT) was examined in a 5-year prospective study. RESULTS We identified 15 polymorphisms in the ADIPOQ gene, ten of them constituting the tagging SNPs. At 5 years, 39.7% of the subjects with IGT had regressed to NGT, 41.2% had persistent IGT or impaired fasting glucose and 19.1% had developed diabetes. Only the T45G polymorphism was associated with persistent hyperglycaemia at 5 years (p=0.001). Haplotypes formed by the addition of other SNPs, as haplotype blocks or pairs, did not confer greater association than T45G alone. On logistic regression analysis, T45G independently predicted persistent hyperglycaemia at 5 years (OR=2.25, 95% CI 1.29-3.95, G carriers vs TT; p=0.005). It also predicted persistent hyperglycaemia in a nested case-control study involving 158 sex- and age-matched controls with persistent NGT (p=0.012, adjusted for BMI), and that of diabetes or glycaemia progression (p<0.05) in a meta-analysis that also included two published studies in Europid subjects. CONCLUSIONS/INTERPRETATION Our findings support a significant role of this common ADIPOQ gene polymorphism in predicting glycaemic status in southern Chinese people.

Abstract
OBJECTIVE Multiple endocrine neoplasia type 1 (MEN1) is characterized by a triad of neoplasia affecting the parathyroid glands, enteropancreatic endocrine tissue and the anterior pituitary gland. DESIGN In order to define the prevalence of MEN1 germ-line mutations in Southern Chinese patients with MEN1 syndrome, we performed direct sequencing of the entire open reading frame of the MEN1 gene for 12 index patients and their first-degree relatives. RESULTS Six patients had familial MEN1 syndrome and six had apparently sporadic disease. Nine different germ-line mutations at the MEN1 gene were identified, including three novel mutations [248-249delTT in exon 2, K559X(AAG --> TAG) in exon 10 and IVS 2nt + 2(G --> T) in intron 2]. All patients with familial MEN1 syndrome were heterozygous carriers of a germ-line mutation and MEN1-related disorders were only evident in their first-degree relatives who also carried the mutation. All patients with an enteropancreatic lesion were mutation carriers and the absence of mutation in three apparently sporadic MEN1 patients with only hyperparathyroidism and pituitary microadenoma might represent the presence of MEN1 phenocopy. CONCLUSIONS The finding of MEN1 germ-line mutation in all patients with familial MEN1 syndrome suggests that genetic screening should be useful in our population to identify affected individuals within a kindred and allow early detection of MEN1-related tumours.

Abstract
Sulindac is the most extensively investigated clinically relevant chemopreventive nonsteroidal anti-inflammatory drug. Sulindac sulfide is one of the major metabolites of sulindac that is believed to mediate its antitumorigenic effects by inducing apoptosis. Recent evidence suggests that sulindac sulfide engages the mitochondrial pathway involving caspase 9 and Bax to mediate its apoptotic effects [Zhang et al., Science (Wash. DC), 290: 989-992, 2000]. In this report, we demonstrate that sulindac sulfide also engaged the membrane death receptor (DR) pathway to mediate apoptosis. Sulindac sulfide up-regulated DR5 and activated the proximal caspase 8 in various different colon and prostate cancer cell lines. Sulindac sulfide specifically up-regulated the DR5 levels but had no effect on the levels of other DRs including DR4, Fas, and tumor necrosis factor receptor 1. To further delineate the role of DR5 in sulindac sulfide-induced apoptosis, we used JCA-1 prostate cancer cells that are deficient in mounting a Fas and tumor necrosis factor receptor 1-dependent apoptotic response but are proficient in mediating DR5-dependent apoptosis. JCA-1 cells were stably transfected with dominant-negative Fas-associated death domain to block the flow of apoptotic signals originating from the endogenous DR5, and sulindac sulfide-induced apoptosis was investigated. Our results indicated that by blocking the DR5-dependent apoptotic pathway, dominant-negative Fas-associated death domain did indeed inhibit sulindac sulfide-induced apoptosis. Furthermore, exogenous tumor necrosis factor-related apoptosis-inducing ligand, the ligand for DR5, also potentiated sulindac sulfide-induced apoptosis in all of the cell lines tested, thereby further supporting the involvement of DR5 in sulindac sulfide-induced apoptosis. Thus, our results demonstrate that sulindac sulfide also engages the membrane DR pathway involving DR5 and proximal caspase 8 to induce apoptosis.

Abstract
Black sesame melanin, a kind of biopolymer was degraded by alkali fusion to study structure characterization. The degraded products were derivatized with bis-(trimethylsilyl) trifloroacetamide in a sealed tube at 125 degrees C for 30 min. The silylanization derivatives of degradation products were analyzed by GC/MS. Catechol, 1,4-dihydroxy benzene and catechuic acid were detected. This method can be used to characterize the structure type of black sesame melanin.

Abstract
DsRNAs were detected in 85/108 isolates of Discula destructiva, the cause of dogwood anthracnose, collected in South Carolina, Idaho, and Alabama. The eastern isolates contained a greater diversity of dsRNA than did Idaho isolates, but most isolates, irrespective of state of origin, contained two small bands (ca. 1.5-2.5 kb) with sequence homology indicated by Northern hybridization. Differences in the banding patterns suggest that genetic diversity of dsRNA in D. destructiva is generated rapidly and that D. destructiva can be simultaneously infected by multiple dsRNA viruses.

Abstract
The primary neuroendocrine interface, hypothalamus and pituitary, together with adrenals, constitute the major axis responsible for the maintenance of homeostasis and the response to the perturbations in the environment. The gene expression profiling in the human hypothalamus-pituitary-adrenal axis was catalogued by generating a large amount of expressed sequence tags (ESTs), followed by bioinformatics analysis (http://www.chgc.sh.cn/ database). Totally, 25,973 sequences of good quality were obtained from 31,130 clones (83.4%) from cDNA libraries of the hypothalamus, pituitary, and adrenal glands. After eliminating 5,347 sequences corresponding to repetitive elements and mtDNA, 20,626 ESTs could be assembled into 9, 175 clusters (3,979, 3,074, and 4,116 clusters in hypothalamus, pituitary, and adrenal glands, respectively) when overlapping ESTs were integrated. Of these clusters, 2,777 (30.3%) corresponded to known genes, 4,165 (44.8%) to dbESTs, and 2,233 (24.3%) to novel ESTs. The gene expression profiles reflected well the functional characteristics of the three levels in the hypothalamus-pituitary-adrenal axis, because most of the 20 genes with highest expression showed statistical difference in terms of tissue distribution, including a group of tissue-specific functional markers. Meanwhile, some findings were made with regard to the physiology of the axis, and 200 full-length cDNAs of novel genes were cloned and sequenced. All of these data may contribute to the understanding of the neuroendocrine regulation of human life.

Abstract
Anecdotal reports of fertility in female mules (jack donkey x mare) and hinnies (stallion x jenny donkey) have appeared in the literature over the years, but scientists have generally regarded them with scepticism. The fact that some of these hybrids can come into estrous and ovulate makes fertility conceivable, given that opportunity for mating arises. In China, where mules are bred extensively for work on the farms, a fertile female mule and a fertile female hinny have now been verified by chromosomal investigation. Each had mated with a donkey and produced a filly foal. The foals show unique hybrid karyotypes different from the mule's or hinny's and different from each other's. The studies make it clear that mule and hinny fertility, at least for the female hybrid, is a real possibility.
