ABSTRACT

Objective: To analyze the migration of the HIV/AIDS cases and related factors in Liangshan Yi autonomous prefecture (Liangshan). Methods: According to HIV/AIDS Comprehensive Response Information Management System of China Information System for Disease Control and Prevention, a total of 28 772 HIV/AIDS cases who had follow-up records in Liangshan in 2020 were included in the survey. The migration of the HIV/AIDS cases was described and the related factors were analyzed using multiple logistic regression models, and the migration destinations of the HIV/AIDS cases were mapped. Results: Among the 28 772 HIV/AIDS cases, 20.89% (6 010/28 772) had migration in 2020. Multivariate logistic regression analysis showed that among the HIV/AIDS cases, the migration related factors included being aged 15-24 years (compared with being aged 0-14 years, OR=2.74, 95%CI:2.04-3.69) and ethnic group (compared with Han ethnic group, OR=2.44, 95%CI:2.19-2.72), having education level of junior high school (compared with having education level of primary school or below, OR=1.25, 95%CI:1.14-1.38), being unmarried (compared with being married, OR=1.29, 95%CI:1.20-1.39), being engaged in business services (compared with being engaged in farming, OR=1.96, 95%CI:1.31-2.92), receiving antiviral treatment <1 year (compared with receiving antiviral treatment >3 years, OR=1.42, 95%CI:1.26-1.61), having recent CD4+T lymphocytes (CD4) counts >500 cells/μl (compared with having recent CD4 counts <200 cells/μl, OR=1.15, 95%CI:1.03-1.29). The geographical distribution maps showed that among all cities in Sichuan, Xichang (13.26%, 797/6 010) and Chengdu (10.12%,608/6 010) were the main migration destinations of the HIV/AIDS cases, and the provinces outside Sichuan where the HIV/AIDS cases would like to migrate to were mainly Guangdong (18.19%, 1 093/6 010) and Zhejiang provinces (7.67%, 461/6 010) in 2020. The HIV/AIDS cases who migrated where Liangshan, within Sichuan province, and to other provinces accounted for 27.67% (1 663/6 010), 15.34% (922/6 010) and 56.99% (3 425/6 010), respectively. Conclusions: More attention should be paid to the mobility characteristics and the classification management of HIV/AIDS cases according to their characteristics in Liangshan. Timely access to information on changes in the place of work and residence of HIV/AIDS cases should be warranted when they have migration. Good referrals and management for mobility of HIV/AIDS cases in different places should be made to reduce loss to follow-up and improving interventions.

ABSTRACT

Under the guidance and support of national policies in recent years, the community medical system has been developed rapidly, among which primary child healthcare is carried out routinely in community hospitals, greatly alleviating the pressure of specialized pediatric hospitals and departments of pediatrics in secondary and tertiary general hospitals. However, due to the lack of professional training for primary child healthcare personnel in community medical institutions, early symptoms of children with cerebral palsy cannot be identified and so children with cerebral palsy are often unable to receive early diagnosis and intervention, which may affect their prognosis. An article about international expert consensus and recommendations on early identification and referral of cerebral palsy in community medical institutions was published in

ABSTRACT

Chimeric antigen receptor T cell (CAR-T) therapy was awarded as the largest research breakthrough in 2017 by the American Society of Clinical Oncology, at present, it is rapidly becoming the most promising new treatment for hematological malignancies. However, this therapy also produces a new challenge: toxic adverse events such as cytokine release syndrome (CRS) and neurotoxicity, partial of them can bring death to the patients. The incidence and severity of the above toxic events in different multi-center trial reports are also different, which may be attributed to the different in the considerably variable assessment and grading of toxicities between clinical trials and across institutions. The ASTCT published at 2018 advanced the consensus grading for cytokine release syndrome and neurologic toxicity associated with immune effector cells, it was focusing on CRS and neurotoxicity associated with immune effector cells. In order to provide reference for the development of relevant work in this field and the formulation of security strategies in our country, the main content of the consensus was summarized briefly.

ABSTRACT

@#Objective    To explore the clinical effect of mitral valvuloplasty on children with Barlow disease combined with moderate to severe or severe mitral regurgitation. Methods    The clinical data of 10 patients with Barlow disease combined with moderate to severe or severe mitral regurgitation in Fuwai Hospital from January 2014 to August 2019 were analyzed retrospectively, including 3 males and 7 females, with a mean age of 8.7±7.9 years. Echocardiography before and during the operation confirmed that the mitral valve leaflets were long and swinging, the valve leaflets and the opposite edge protruded into the left atrium and were higher than the level of the mitral valve rings, the mitral valve rings were dilated, the papillary muscles and tendons were long, and the pathological changes after the operation showed mucoid degenertion of the valve leaflets and tendons, and some fibrous foci hyperplasia. Mitral valve repair included implantation of artificial valve ring, implantation of artificial tendon, posterior leaflets sliding, partial resection of posterior leaflets (excluding sliding), valve leaflets folding, tendon folding, papillary muscle splitting and annular valve contraction (excluding artificial valve ring implantation). The technique of mitral valve repair, early clinical results and follow-up echocardiographic data were analyzed. Results    All the patients successfully completed the mitral valve repair. The mean time of aortic occlusion was 73.2±17.4 min, and cardiopulmonary bypass time was 99.5±19.8 min. At the same time, 4 patients received tricuspid valve repair and 1 funnel chest correction. There was no reoperation in perioperative period. The 1-year and 5-year survival rates were 100.0% and 100.0%, respectively. The incidence of below moderate mitral regurgitation was 90.0% at postoperative 1 year and 72.0% at postoperative 5 years. Conclusion    For the young children who have Barlow disease and mitral regurgitation, considering the characteristics of heavy lesions, small operation space, and the need to meet the growth and development of valve, it is suggested to adopt the surgical techniques different from those of older children, such as valve ring retraction and tendon folding, if necessary, to adopt "edge to edge" suture, which can shorten aortic occlusion time and achieve good early effects, and its long-term effects still need further follow-up observation. Mitral valvuloplasty technique for Barlow disease similar to that of adults can be used in older children, including implantation of artificial valve ring and implantation of artificial tendon, etc.

ABSTRACT

Objective:To study the quality evaluation method of Cyperi Rhizoma processed with four excipients. Method:Ultra-performance liquid chromatography (UPLC) fingerprints of raw products and processed products with four excipients of Cyperi Rhizoma were established, and the changes of chemical components in the fingerprints before and after processing were compared by chemometric analysis. The mobile phase was consisted of methanol (A)-water (B) for gradient elution (0-10 min, 5%-40%A; 10-30 min, 40%-70%A; 30-40 min, 70%A) at a flow rate of 0.3 mL·min<sup>-1</sup>. The injection volume was 3 μL, the column temperature was 35 ℃, and the detection wavelength was 280 nm. The content changes of main index components in Cyperi Rhizoma before and after processing were compared by UPLC. The mobile phase was methanol-water (75∶25) and the detection wavelength was 242 nm. Result:Processing with four excipients had a significant impact on the overall characteristics of chemical components in the fingerprint of Cyperi Rhizoma. A total of 28 characteristic peaks were identified in fingerprints of the raw and processed products. Among them, peaks 1, 2 and 4 were specific peaks of the processed products, peak 5 was characteristic peak of the raw products. Peak 2 was identified as 5-hydroxymethylfurfural, peak 24 as cyperenone and peak 27 as <italic>α</italic>-cyperone. The 5-hydroxymethylfurfural produced by the processing with four excipients came from rice vinegar, rice wine and Maillard reaction of polysaccharides in Cyperi Rhizoma. The results of determination showed that there was no significant difference in the content of cyperenone after processing, but the content of <italic>α</italic>-cyperone decreased significantly. Conclusion:In the process of Cyperi Rhizoma processed with four excipients, there are new components produced by structural transformation, which are accompanied by changes in the content of index components. In this study, the quality of raw and processed products of Cyperi Rhizoma can be rapidly and effectively evaluated from qualitative and quantitative aspects.

ABSTRACT

@#Objective    To investigate the best anatomical classification, surgical timing, procedure and clinical outcomes of congenital vascular ring. Methods    The clinical data of 58 patients who underwent congenital vascular ring surgery in Pediatric Surgery Center, Fuwai Hospital between 2014 and 2019 were retrospectively analyzed. There were 32 (55.2%) males and 26 (44.8%) females with a median age of 16.5 (2-73) months. Preoperative symptoms, imaging examinations, anatomical classifications, surgical procedures and postoperative recovery were assessed. Results    There were 20 (34.5%) patients of double aortic arch, 22 (37.9%) patients of right aortic arch with left arterial duct or ligament, 15 (25.9%) patients of left aortic arch with aberrant right subclavian artery, and 1 (1.7%) patient of circumflex aorta with cervical aorta arch. The median ventilator supporting time was 6.0 (0-648) h, and the median hospital stay time was 14.5 (7-104) d. One patient with coarctation of aorta died of severe pulmonary infection during perioperative period, and the others survived without symptoms and reoperation after discharge. The median follow-up time was 7.0 (1-62) months. Conclusion    For children with unexplained dyspnea and dysphagia, or with right aortic arch, preoperative imaging examinations such as computed tomography or magnetic resonance imaging are required to confirm the diagnosis of vascular ring. Surgical correction of congenital vascular ring is safe and reliable, and can effectively relieve symptoms. The mortality rate and reoperation rate are low, and the follow-up results are satisfactory.

ABSTRACT

An UPLC-MS/MS method was developed to simultaneously determine complanatoside A and complanatoside B in rat plasma with rutin as the internal standard and applied to examine the effect of salt-processing on pharmacokinetics of these two flavonoid glycosides. The pharmacokinetic parameters were estimated using DAS 3.2.6 and subjected to independent sample t-test with SPSS 23.0. No significant difference in T_(max) of complanatoside B was observed between the raw and processed groups; however, in the processed group, C_(max) and AUC_(0-12 h) of complanatoside B increased obviously(P<0.05), while MRT_(0-12 h) decreased from(3.34±0.44) h to(1.81±0.36) h(P<0.05). C_(max) [(14.72±11.13) μg·L~(-1)] and MRT_(0-24) [(3.93±0.26) h] of complanatoside A in the raw group were statistically different from those [(35.64±21.99) μg·L~(-1),(1.43±0.24) h] in the processed group(P<0.05). As a result, salt-processing can facilitate the in vivo adsorption and accelerate the excretion of complanatoside A and complanatoside B.

ABSTRACT

RESUMEN Durante las primeras semanas de 2020 se comenzaron a informar casos de personas con SARS-CoV-2 fuera de China, con un rápido aumento de casos y muertes en todo el mundo. El SARS-CoV-2 es un virus ARN monocatenario positivo, envuelto en una bicapa lipídica derivada de la membrana celular del huésped y constituido por cuatro proteínas estructurales (S, M, E y N), además de una hemaglutinina-esterasa. La unión de la proteína S con el receptor de enzima convertidora de angiotensina 2 (ECA2) permite la entrada del virus a la célula huésped y es una potencial diana terapéutica. El 81% de los enfermos hace cuadro leve; el 14%, grave; y el 5% requiere cuidados intensivos. La fiebre es el síntoma más frecuente, seguido de tos y disnea. La mayoría de los pacientes no presentan leucocitosis pero sí linfopenia, con cultivos de esputo que no muestran otros patógenos. En las biopsias de pulmón de pacientes graves el hallazgo más llamativo es el daño alveolar difuso. Radiológicamente se aprecian patrones de vidrio esmerilado y alveolar, siendo las lesiones de predominio basal, subpleural y posterior, con una distribución periférica multifocal, afectando más el lóbulo inferior derecho. Hay una marcada respuesta inflamatoria, que llega hasta la tormenta de citoquinas, en la que el tratamiento antiinflamatorio con terapia de pulso con metilprednisolona estaría indicado. Aunque no existan estudios en gran escala respecto al uso de cloroquina/hidroxicloroquina, debido a la situación mundial se ha autorizado su uso por su efecto anti SARS-CoV-2 y anti-inflamatorio, el cual puede ser potenciado con el uso de azitromicina.


ABSTRACT During the first weeks of 2020, cases of SARS-CoV-2 began to be reported outside of China, with a rapid increase in cases and deaths worldwide. SARS-CoV-2 is a positive single-stranded RNA virus, encased in a lipid bilayer derived from the host cell membrane and consists of four structural proteins (S, M, E and N), plus a haemagglutinin-sterase. The binding of the S protein to the ECA2 receptor allows the entry of the virus into the host cell and is a potential therapeutic target. 81% of patients develop mild symptoms, 14% have severe symptoms and 5% require intensive care management. Fever is the most frequent symptom, followed by cough and dyspnea. Most patients do not present leukocytosis, but they do present lymphopenia with sputum cultures that do not show other pathogens. In lung biopsies of severe patients, the most noticeable finding is diffuse alveolar damage. Radiologically, ground glass and alveolar patterns are observed; the lesions being predominantly basal, subpleural, and posterior, with a multifocal peripheral distribution, more affecting the right lower lobe. There is a marked inflammatory response, up to the cytokine storm, in which anti-inflammatory treatment with pulse therapy with methylprednisolone would be indicated. Although there are no large-scale studies regarding the use of chloroquine / hydroxychloroquine, due to the global situation, its use has been authorized for its anti-SARS-CoV-2 and anti-inflammatory effect, which can be potentiated with the use of azithromycin.

ABSTRACT

To investigate the effects of different habitat processing methods of Salviae Miltiorrhizae Radix et Rhizoma on acute myocardial ischemia induced by pituitrin in rats. In this experiment, the tail vein injection of pituitrin was used to induce acute myocardial ischemia in rats. Electrocardiograph(ECG) heart rate and ΔST changes were recorded, and the levels of creatine kinase isoenzyme(CK-MB), lactate dehydrogenase(LDH), superoxide dismutase(SOD) and malondialdehyde(MDA) in serum of rats were detected to comprehensively evaluate the effects of six processing methods of Salviae Miltiorrhizae Radix et Rhizoma on serum biochemical indexes of rats with acute myocardial injury. The ECG results showed that the Salviae Miltiorrhizae Radix et Rhizoma dried in a drying oven had a good effect on the improvement of heart rate and ΔST of electrocardiogram after ischemia, and all the other groups had some protective effects to different degrees. The results of biochemical indexes in serum of each group after ischemia showed that the activity of CK-MB decreased most significantly in Salviae Miltiorrhizae Radix et Rhizoma high-dose group with drying in a drying oven after sweating and losing weight in a drying oven, high-dose group with drying in the shade and low-dose group with drying in the shade. The activity of LDH decreased most significantly in Salviae Miltiorrhizae Radix et Rhizoma high-dose group with drying in the shade and low-dose group of drying in the shade. The activity of SOD increased most significantly in Salviae Miltiorrhizae Radix et Rhizoma low-dose group with drying in sun, low-dose group with drying in sun after sweating and losing weight in sun, and low-dose group with drying in a drying oven. The activity of MDA decreased most significantly in Salviae Miltiorrhizae Radix et Rhizoma low-dose group with drying in sun. The comprehensive scoring results showed that the highest score was obtained in Salviae Miltiorrhizae Radix et Rhizoma high-dose group with drying in the shade while the scores of other treatment groups were higher than that of the model group. It could be seen that the Salviae Miltiorrhizae Radix et Rhizoma dried in a drying oven had a good improvement effect on electrocardiograph indexes after acute myocardial injury, the Salviae Miltiorrhizae Radix et Rhizoma dried in the shade had a good improvement effect on serum myocardial enzymes after acute myocardial injury, and the other processing methods had a certain protective effect on myocardial injury. The six processing methods evaluated by pharmacodynamics showed that the Salviae Miltiorrhizae Radix et Rhizoma dried in the shade and dried in a drying oven had good efficacy.

ABSTRACT

This paper aimed to investigate the active components and mechanism of Taohong Siwu Decoction in the treatment of primary dysmenorrhea(PD) based on network pharmacology and molecular docking technology. Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP) was used to search the chemical compositions and targets of six herbs in Taohong Siwu Decoction. The targets for PD treatment were selected through the databases of DrugBank, OMIM, TTD and CTD, and gene annotation of the targets was conducted with UniProt database. Cytoscape 3.7.2 was then used to construct the drug-compound-target network. The protein-protein interaction(PPI) network was constructed based on STRING, and the core targets of Taohong Siwu Decoction in the treatment of PD were selected according to the topological parameters. David database was used for GO enrichment analysis and KOBAS 3.0 was used for KEGG enrichment analysis. The molecular docking technology was used to connect the components with higher medium values in the network with core targets. The results showed that the network contained 36 compounds such as quercetin, kaempferol, luteolin, myricanone and ferulic acid, and 99 targets such as PTGS2, PTGS2, PGR and PPARG. Totally 102 GO terms were obtained by GO functional enrichment analysis(P<0.01), and 228 signal pathways were obtained by KEGG pathway enrichment(P<0.05), mainly involving inflammatory factors, hormone regulation, central analgesia, amino acid metabolism and spasmolysis. The results of molecular docking showed that the main active components can spontaneously bind to the targets. This study preliminarily revealed the mechanism of Taohong Siwu Decoction for treatment of primary dysmenorrheal through multi-components, multi-targets and multi-pathways, providing theoretical references for further researches on mechanism of Taohong Siwu Decoction.

ABSTRACT

Viral warts are benign proliferations of the epithelium caused by human papilloma virus (HPV) infection. Diverse therapeutic options are available for viral warts, depending on extension and severity of the disease. We report a case of a 19-year-old man who presented with multiple viral warts on hands and feet for 5 years. He was treated at other clinics before visiting our hospital, but there was no improvement. We treated the lesions with a combination therapy of systemic acitretin and diphenylcyclopropenone (DPCP) immunotherapy for 6 months. A significant improvement was observed during the 12th week of therapy. Herein, we report a case of recalcitrant viral warts showing complete regression when a combination therapy of oral acitretin and immunotherapy was administered.

ABSTRACT

We report a 29-year-old female with a one-month history of non-healing multiple erythematous to violaceous plaques with crusts over both legs and feet. Tender, scarring ulcers with surrounding erythema were present. The clinical manifestation, together with histopathologic findings of fibrinoid plugs within vascular lumens and walls, as well as red blood cell extravasation, led to diagnosis of livedoid vasculopathy.The patient experienced recurrent painful violaceous plaques with ulcerations during the two years of treatment with oral pentoxifylline 400 mg three times daily. The cutaneous lesions and symptoms dramatically improved after the treatment regimen changed to oral sulodexide (250 lipasemic units) three times daily. Sulodexide, a highly purified mixture of glycosaminoglycans including dermatan sulfate and lowmolecular weight heparin, could be an effective therapy for recalcitrant livedoid vasculopathy. Herein, we report a case of livedoid vasculopathy treated with sulodexide, which has not previously been reported.

ABSTRACT

While lymphangioma circumscriptum may present anywhere on the body, the vulva is a rare site. However, vulvar involvement can occur in some clinical settings, and Crohn’s disease is one of the underlying etiologies of acquired lymphangioma circumscriptum. A 31-year-old woman presented with an 8-year history of widespread verruciform plaques on her vulva. She complained of a mild itching sensation at the lesion site. She was diagnosed with Crohn’s disease 11 years prior but had not been treated. She had no history of trauma or surgery in the perineal area and no familial history of cancer or hereditary disorders. The histopathologic findings were consistent with lymphangioma. Based on the clinicopathologic findings, the patient was diagnosed with lymphangioma circumscriptum on the vulva. Herein, we report a rare case of acquired lymphangioma circumscriptum of the vulva mimicking condyloma acuminatum in a patient with Crohn’s disease.

ABSTRACT

Background@#Verruca vulgaris is a common cutaneous viral infectious disease caused by human papilloma virus (HPV). The main treatment modalities are cryotherapy, immunotherapy, laser therapy, intralesional injection of bleomycin, and salicylic acid therapy. However, there is no definitive tool for predicting clinical improvement or treatment response. @*Objective@#This study was designed to evaluate clinical treatment response according to the hardness of verruca vulgaris skin lesions. We developed a new prediction tool called the “hardening sign” that divides the course of treatment into four categories based on inspection and palpation. @*Methods@#We conducted a retrospective medical chart review of patients who visited Hanyang University Guri Hospital between January 2016 and January 2017 and were clinically diagnosed with verruca vulgaris. We divided the patients into four groups according to the grade of rigidity of their lesions. @*Results@#Forty-seven patients (24 male and 23 female) were identified. The mean age at diagnosis was 17.2±8.5 years, and the mean duration of treatment was 28.8±27.7 weeks. The mean number of hospital visits was 16.5±12.4. Eleven patients underwent only cryotherapy, while 36 patients underwent combined cryotherapy and immunotherapy. We observed significantly shorter durations of treatment for patients with higher grades of hardening. There was no correlation between the hardening grade and the number of treatments required for patients to be completely cured. @*Conclusion@#This study suggests that the therapeutic response of verruca vulgaris warts to cryotherapy can be easily predicted by careful consideration of the “hardening sign”.
