ABSTRACT
Magnetic cell sorting technology is a highly specific and rapid cell sorting technology using superparamagnetic nanocomposites for cell sorting, which is widely used in immunology, stem cytology, oncology, clinical medicine and other fields. Magnetic cell sorting technology is divided into positive isolation, negative isolation/untouched cell isolation, depletion, multi-step isolation and automated cell separation systems. In this review, we firstly give a brief introduction to the classification and application of magnetic cell sorting technology, then discuss several new techniques and challenges based on magnetic cell sorting in recent years, such as improving the sorting efficiency by improving the structure of magnetic materials and magnetic field structure. The necessity of biological evaluation of magnetic cell sorting products was emphatically analyzed. Through the biological evaluation, the advantages and disadvantages of magnetic cell sorting products can be understood, and the research and development ability could be improved. Therefore, 10 biological evaluation technical parameters related to magnetic cell sorting products were proposed: yield, purity, sterility, cytotoxicity, cell morphology, viability, light scattering characteristics of cells, fluorescent antibody labeling ability of cells, cell activation and cell proliferation. The 10 biological evaluation technical parameters play an important role in promoting the standardized application of magnetic cell sorting.
ABSTRACT
Objective To investigate the effect and mechanism of osteopontin(OPN)in hepatoma cell migration through galectin-3 binding protein(LGALS3BP).Methods Human hepatoma cell lines SMMC-7721,SMMC-P(stably transfected with empty eukaryotic expression vectors),and SMMC-OPN(stably transfected with the OPN gene)were cultured.mRNA expression levels of OPN and LGALS3BP were measured by RT-qPCR.Western blot assays were used to analyze the relative protein expression of OPN and LGALS3BP and PI3K/AKT pathway.Wound healing assays were performed to explore the cell migration ability.After transfection with LGALS3BP-targeting small interfering RNA(si-LGALS3BP)or negative control small RNA(si-NC)into SMMC-OPN cells,cell migration and relative expression of PI3K/AKT pathway-related proteins were assessed.Results Compared with SMMC-7721 and SMMC-P,the migratory ability of SMMC-OPN cells was significantly reinforced,and expression of LGALS3BP was obviously upregulated at both mRNA and protein levels.Moreover,relative expression of p-PI3K/PI3K and p-AKT/AKT proteins was significantly increased.Wound healing assays showed that the si-LGALS3BP obviously suppressed the migratory ability of SMMC-OPN cells.Furthermore,relative expression of p-PI3K/PI3K and p-AKT/AKT proteins in SMMC-OPN cells was significantly decreased after transfection of si-LGALS3BP.Conclusions OPN activates the PI3K/AKT pathway by upregulating LGALS3BP expression to promote hepatoma cell migration.

ABSTRACT
Multiple myeloma (MM) is an incurable plasma cell malignancy with a typical course characterized by response to initial treatment and eventual resistance. Despite major advances in the clinical treatment of multiple myeloma driven by the introduction of new drugs (e.g., proteasome inhibitors and immunomodulators), MM remains incurable. Nevertheless, subsequent cycles of remission and relapse continue as long as new treatments are available to patients. With the development of many new treatments, the approval of 12 new drugs over the past 15 years, and the promising trend of clinical trials, the treatment landscape has dramatically changed and patient survival has improved. This article reviews the progress of new treatments for MM.
ABSTRACT
OBJECTIVE@#Moxibustion, a common therapy in traditional Chinese medicine, has potential benefits for treating decreased ovarian reserve (DOR). The present study investigates the protective effect of moxibustion in a rat model of DOR and explores the possible mechanisms.@*METHODS@#Sixty-four female Sprague-Dawley rats were randomly divided into four groups: control, DOR, moxibustion (MOX), and hormone replacement therapy (HRT). The DOR rat model was established by intragastric administration of 50 mg/kg Tripterygium glycoside suspension (TGS), once daily for 14 days. MOX and HRT treatments were given from the day TGS administration was initiated. The ovarian reserve function was evaluated by monitoring the estrus cycle, morphological changes in ovaries, levels of serum estradiol (E2), follicle-stimulating hormone (FSH), luteinizing hormone (LH), and anti-Mullerian hormone (AMH), pregnancy rate and embryo numbers. Terminal-deoxynucleotidyl transferase-mediated nick-end-labeling staining was used to identify ovarian granulosa cell apoptosis, while the protein and mRNA expressions of Bax, B-cell lymphoma-2 (Bcl-2), phosphatidylinositol 3-kinase (PI3K) and protein kinase B (AKT) in ovarian tissues were examined by immunohistochemistry, Western blot and quantitative reverse transcription-polymerase chain reaction.@*RESULTS@#Compared with the DOR group, MOX improved the disordered estrous cycle, promoted follicular growth, reduced the number of atresia follicles, increased the concentrations of serum E2 and AMH, and decreased serum FSH and LH concentrations. More importantly, the pregnancy rate and embryo numbers in DOR rats were both upregulated in the MOX treatment group, compared to the untreated DOR model. Further, we found that the MOX group had reduced apoptosis of ovarian granulosa cells, increased Bcl-2 expression and reduced expression of Bax. Furthermore, the PI3K/AKT signaling pathway was triggered by the moxibustion treatment.@*CONCLUSION@#Moxibustion improved ovarian function and suppressed apoptosis of ovarian granulosa cells in a rat model of DOR induced by TGS, and the mechanism may involve the PI3K/AKT signaling pathway.

OBJECTIVE@#To compare the clinical efficacy between Jiao's scalp acupuncture combined with virtual reality (VR) rehabilitation training and VR rehabilitation training alone for motor dysfunction in patients with Parkinson's disease (PD).@*METHODS@#A total of 52 patients with PD were randomly divided into an observation group and a control group, 26 cases in each group. The patients in both groups were treated with routine basic treatment, and the patients in the control group were treated with VR rehabilitation training. The patients in the observation group were treated with Jiao's scalp acupuncture on the basis of the control group. The scalp points included the movement area, balance area and dance tremor control area. Both groups were treated once a day, 5 times a week for a total of 8 weeks. Before treatment and 4 and 8 weeks into treatment, the gait parameters (step distance, step width, step speed and step frequency), timed "up and go" test (TUGT) time and unified Parkinson's disease rating scale part Ⅲ (UPDRS-Ⅲ) score were compared between the two groups, and the clinical efficacy was evaluated.@*RESULTS@#Four weeks into treatment, except for the step width in the control group, the gait parameters of the two groups were improved, the TUGT time was shortened, and the UPDRS-Ⅲ scores were reduced (P<0.01, P<0.05); the step distance in the observation group was better than that in the control group, and the UPDRS-Ⅲ score in the observation group was lower than that in the control group (P<0.05). Eight weeks into treatment, the gait parameters of the two groups were improved, the TUGT time was shortened, and the UPDRS-Ⅲ scores were reduced (P<0.01); the step distance and step speed in the observation group were better than those in the control group, the TUGT time in the observation group was shorter than that in the control group, and the UPDRS-Ⅲ score in the observation group was lower than that in the control group (P<0.05, P<0.01). The total effective rate was 92.3% (24/26) in the observation group, which was higher than 69.2% (18/26) in the control group (P<0.05).@*CONCLUSION@#Jiao's scalp acupuncture combined with VR rehabilitation training could improve the gait parameters, walking ability and motor function in patients with PD. The clinical effect is better than VR rehabilitation training alone.

ObjectiveTo explore the syndrome and treatment rules of traditional Chinese medicine (TCM) in treating chronic obstructive pulmonary disease (COPD) based on the medical literature and cases with the help of TCM inheritance support system platform (V2.5), thus providing new ideas for TCM to treat COPD. MethodThe medical cases of TCM treating COPD were retrieved from China national knowledge infrastructure (CNKI), Wanfang Database, and VIP China Science and Technology Journal Database. The medical cases that met the inclusion literature were collected in a new Word document, and then input into the TCM inheritance support system platform (V2.5) after data standardization. With the help of the algorithm carried by this software, the frequency statistics of "symptoms, syndrome types of TCM, Chinese medicine, and meridians of Chinese medicine" in the included COPD medical cases were performed, and the correlation analysis of the "prescription rules" in the included medical cases was carried out, thus excavating the potential core drug pairs and new prescriptions for the treatment of COPD. ResultA total of 103 articles were included with 126 medical cases and 131 diagnoses and treatments. According to statistics, the common symptoms of COPD were cough, expectoration, chest tightness, and asthma, and the common TCM syndromes included phlegm-heat obstructing lung, phlegm and blood stasis blocking lung, and lung-spleen Qi deficiency. The common TCM treatment methods included clearing heat and resolving phlegm, banking up earth to generate metal, and descending adverse and relieving dyspnea, among which the high-frequency Chinese medicines for the treatment of COPD were Pinelliae Rhizoma, Armeniacae Semen Amarum, Ephedrae Herba, Citri Reticulatae Pericarpium, and so on. The commonly used drug pairs included Asari Radix et Rhizoma-Pinelliae Rhizoma, Pinelliae Rhizoma-Schisandrae Chinensis Fructus-Glycyrrhizae Radix et Rhizoma, etc. Twelve new prescriptions for the treatment of COPD were found. ConclusionTCM believes that COPD is a lung disease formed by external evil, phlegm, blood stasis, and other pathological factors, with cough, phlegm, and asthma as the main symptoms. The main syndromes of COPD are phlegm-heat obstructing lung, phlegm and blood stasis blocking lung, and lung-spleen qi deficiency. "Strengthening the upright and dispelling evil" is the basic principle of the treatment COPD. In clinical, TCM methods with dispelling phlegm and removing blood stasis, and tonifying lung, spleen, and kidney should be adopted to treat COPD.
ABSTRACT
This study aims to compare the prevalence of sexually transmitted infections (STIs) with semen quality in men from couples with primary and secondary infertility. Semen samples were collected from 133 men who requested fertility evaluation. Seminal tract infection with Ureaplasma spp. (UU), Mycoplasma hominis (MH), Mycoplasma genitalium (MG), Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and herpes simplex virus-2 (HSV-2) was assessed by PCR-based diagnostic assays. Among all patients, the prevalence of STIs was higher in men from couples with primary infertility than that in men from couples with secondary infertility (39.7% vs 21.7%, P = 0.03). The prevalence of UU was 28.8% and 13.3% in men from couples with primary and secondary infertility, respectively. Men from couples with primary infertility were more likely to be positive for UU than men from couples with secondary infertility (P = 0.04). Regarding the UU subtype, the prevalence of Ureaplasma urealyticum (Uuu) and Ureaplasma parvum (Uup; including Uup1, Uup3, Uup6, and Uup14) did not differ between the two groups. No associations between the prevalence rates of MH, MG, and CT were found in men from either infertility group. A lower sperm concentration was associated with STI pathogen positivity in men with primary infertility according to the crude model (P = 0.04). The crude and adjusted models showed that semen volume (both P = 0.03) and semen leukocyte count (both P = 0.02) were independently associated with secondary infertility. These findings suggest the importance of classifying the type of infertility during routine diagnosis of seminal tract infections.

This study aimed to establish nomograms to preoperatively predict the possibility of testicular salvage (TS) in patients with testicular torsion. The clinical data of 204 patients with testicular torsion diagnosed at Xijing Hospital and Tangdu Hospital (Xi'an, China) between August 2008 and November 2019 were retrospectively analyzed. Univariate and multivariate logistic regression analyses were used to determine the independent predictors of TS. Based on multivariate regression coefficients, nomograms to predict possibility of TS were established. The predictive ability of the nomograms was internally validated by receiver operating characteristic (ROC) curves and calibration plots. The duration of symptoms ranged from 2 h to 1 month, with a median of 3.5 days. Thirty (14.7%) patients underwent surgical reduction and contralateral orchiopexy, while the remaining 174 (85.3%) underwent orchiectomy and contralateral orchiopexy. Finally, long symptom duration was an independent risk predictor for TS, while visible intratesticular blood flow and homogeneous testicular echotexture under color Doppler ultrasound were independent protective predictors. Internal validation showed that the nomograms, which were established by integrating these three predictive factors, had good discrimination ability in predicting the possibility of TS (areas under the ROC curves were 0.851 and 0.828, respectively). The calibration plots showed good agreement between the nomogram-predicted possibility of TS and the actual situation. In conclusion, this brief preoperative prediction tool will help clinicians to quickly determine the urgency of surgical exploration.
ABSTRACT
Upon his untimely death, Michal Boym (1612-1659) left behind an enormous written legacy; covering a diverse range of interests in fields such as Chinese linguistics, cartography, botany, zoology, philosophy and medicine. This article attempts to examine Boym's De indiciis morborum ex linguae coloribus & affectionibus (The signs of disease on the tongue, colors and affections), a translation of a previously unidentified Chinese text. The text specifically deals with the subject of tongue diagnosis, in relation to contagious diseases that were still raging in the 17th century China. Arriving to China at the end of the Ming Dynasty (1368-1644), Boym was able to personally witness the early development of tongue examination as an independent specialty; he recognized its significance and tried to incorporate it into his ultimately unfinished Chinese medical corpus. Boym's work eventually facilitated the assimilation of tongue observation in European medicine during the 19th century.
ABSTRACT
Drug metabolism is an orchestrated process in which drugs are metabolized and disposed through a series of specialized enzymes and transporters. Alterations in the expression and/or activity of these enzymes and transporters can affect the bioavailability (pharmacokinetics, or PK) and therapeutic efficacy (pharmacodynamics, or PD) of drugs. Recent studies have suggested that the long non-coding RNAs (lncRNAs) are highly relevant to drug metabolism and drug resistance, including chemo-resistance in cancers, through the regulation of drug metabolism and disposition related genes. This review summarizes the regulation of enzymes, transporters, or regulatory proteins involved in drug metabolism by lncRNAs, with a particular emphasis on drug metabolism and chemo-resistance in cancer patients. The perspective strategies to integrate multi-dimensional pharmacogenomics data for future in-depth analysis of drug metabolism related lncRNAs are also proposed. Understanding the role of lncRNAs in drug metabolism will not only facilitate the identification of novel regulatory mechanisms, but also enable the discovery of lncRNA-based biomarkers and drug targets to personalize and improve the therapeutic outcome of patients, including cancer patients.
ABSTRACT
Objective:To detect and analyze the contents of eight metal elements in water samples of plague foci in Yunnan Province.Methods:During the period from December 2015 to November 2016, the plague foci of Yulong, Jianchuan and Lianghe were selected as sampling sites, water samples were collected in areas with rodent activities in the 4 seasons of spring, summer, autumn and winter. The contents of eight metal elements calcium (Ca), iron (Fe), zinc (Zn), chromium (Cr), plumbum (Pb), manganese (Mn), cadmium (Cd) and cuprum (Cu) in water samples were measured by flame atomic absorption spectrometry (FAAS), and the data [median (interquartile distance)] were statistically analyzed.Results:Twenty-six, 58 and 54 water samples were collected from Yulong, Jianchuan and Lianghe plague foci, respectively. The contents of metal elements of Pb and Cd in water samples of the three plague foci [Yulong: 0.19 (0.78) and 0.08 (0.07) mg/L; Jianchuan: 0.23 (0.56) and 0.03 (0.06) mg/L; Lianghe: 0.13 (0.61) and 0.09 (0.08) mg/L] were higher than that of "Environmental Quality Standards for Surface Water" (Pb: 0.10 mg/L, Cd: 0.01 mg/L). There were significant differences in the contents of Ca and Cd elements among the three regions ( P < 0.05), but there was no significant difference in the contents of the other 6 metal elements among the three regions ( P > 0.05). The content of Ca element was the highest in Yulong plague foci, and the lowest in Lianghe plague foci ( P < 0.017). In the Yulong plague foci, there was no statistically significant difference in the content of Fe element in different seasons ( P > 0.05), and the differences in the contents of the other 7 metal elements were statistically significant ( P < 0.05). There was no significant difference in the content of Cr element in Jianchuan plague foci in different seasons ( P > 0.05), and the differences in the content of the other 7 metal elements were statistically significant ( P < 0.05). There was no significant difference in the content of Ca element in Lianghe plague foci in different seasons ( P > 0.05), and the differences in the content of the other 7 metal elements were statistically significant ( P < 0.05). Conclusion:The metal element contents of Pb and Cd are relatively abundant in water samples from 3 plague foci of Yunnan Province, and the seasonal variation trend of metal element content in water samples of Yulong and Jianchuan plague foci is similar.
ABSTRACT
Objective To evaluate the clinical efficacy and safety of hydroxychloroquine sulfate combined with azithromycin in the treatment of refractory common coronavirus disease 2019 (COVID-19) patients. Methods The clinical data of 11 refractory common COVID-19 patients, who were admitted to Guanggu Branch of Maternity and Child Healthcare Hospital of Hubei Province from Mar. 22 to 25, 2020, were retrospectively collected. The patients all received combined treatment regimens: hydroxychloroquine sulfate orally 200 mg three times daily for 7 days; and azithromycin orally 500 mg once daily on day 1 and then 250 mg once daily from day 2 to day 4. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleic acid test of throat swab was performed once daily from day 4 to day 10 after combined administration, and the blood routine and other laboratory indicators were tested within 3 days before administration and on the 8th days after administration. Results All the 11 patients had common COVID-19, seven of them were consistently positive for SARSCoV- 2 nucleic acid test, and four were positive again after negative results. The average course of disease of 11 patients before combined administration was 50.2 days. The treatment process was uneventful. Zero case of SARS-CoV-2 nucleic acid test result turned negative on day 4 after administration, two cases on day 5, two cases on day 6, two cases on day 7, one case on day 8 and one case on day 9. No patients progressed to severe or critical illness, and no severe side effects were found. Conclusion Hydroxychloroquine sulfate combined with azithromycin is safe and effective in the treatment of refractory common COVID-19 patients who have ailed in other treatments and are consistently positive for SARS-CoV-2 nucleic acid.

ABSTRACT
Purpose To observe the clinical characteristics, expression of C4d and the morphology of podocyte lesions in steroid-sensitive minimal change disease (SS-MCD) ,steroidresistant minimal change disease (SR-MCD) and early focal segmental glomerulosclerosis (E-FSGS) ,as well as to analyze their differences among the three groups,and provide a novel method for effective evaluation the therapeutic effects of steroid and diagnosis of SR-MCD. Methods To study the clinical data from 24 cases of SS-MCD,30 cases of SR-MCD and 25 cases of E-FSGS as control,and all the biopsies were examined by light microscopy,immunohistochemistry and transmission electron microscopy. Meanwhile,the clinical characteristics,the morphology of podocyte lesion and the expression of C4d were observed. Results The average score of podocyte lesion of SR-MCD was higher than that of SS-MCD,but lower than that of E-FSGS (P< 0. 05) . C4d positive average score of SS-MCD was lower than that of both SR-MCD and E-FSGS (P < 0. 05) ,but there was no significant difference between SR-MCD and E-FSGS (P > 0. 05) . The sum of the average score of podocyte lesion and C4d positive average score of SS-MCD was lower than that of SRMCD and E-FSGS (P < 0. 01) ,however,there was also no significant difference between SR-MCD and E-FSGS(P > 0. 05) . The scores of IgM,C3d and C1q were not significantly different among the three groups. The area under the receiver operating curve (ROC) of the C4d positive score,podocyte lesion score and the sum of the two were 0. 753,0. 658 and 0. 803,respectively, and there was no significant difference between them and the optimal cutoff values were 3,1. 5,and 4. 5 points,respectively. Conclusions The C4d positive score,podocyte lesion score and the sum of the two scores of MCD (the last one is named for MCD nephropathy score in our study) can be used for evaluating the therapeutic effects of steroid and identification of SR-MCD,most especially MCD nephropathy score. The optimal cut-off values of the three kinds of scores are 3,1. 5,and 4. 5 points,respectively. When the values are exceeded,the clinicians should be reminded to follow-up and take appropriate treatment measures to patients.

The combined use of acupuncture and medicine can synergically enhance the clinical therapeutic effect.
ABSTRACT
To exploring a new minimally invasive method for the removal of moderate and severe glabellar frown lines. The corrugator supercilii muscles were subjected to blunt cutting and vacuum suction by using a self-made modified liposuction needle,and the obtained muscle particles were backfilled subcutaneously into the depression area between eyebrows to expand the wrinkles. Seventeen cases were followed up for six to twelve months after the operation.The glabellar wrinkles disappeared or became flatter in all patients. The minimally invasive corrugator resection and backfill by using self-made modified liposuction needle can effectively remove the glabellar frown lines without forming scar.
