Glycosylphosphatidylinositol biosynthesis deficiency 15 caused by GPAA1 gene mutation: a rare disease study / 中国当代儿科杂志

A boy, aged 6 years, attended the hospital due to global developmental delay for 6 years and recurrent fever and convulsions for 5 years. The boy was found to have delayed mental and motor development at the age of 3 months and experienced recurrent fever and convulsions since the age of 1 year, with intermittent canker sores and purulent tonsillitis. During the fever period, blood tests showed elevated white blood cell count, C-reactive protein, and erythrocyte sedimentation rate, which returned to normal after the fever subsides. Electroencephalography showed epilepsy, and genetic testing showed compound heterozygous mutations in the GPAA1 gene. The boy was finally diagnosed with glycosylphosphatidylinositol biosynthesis deficiency 15 (GPIBD15) and periodic fever. The patient did not respond well to antiepileptic treatment, but showed successful fever control with glucocorticoid therapy. This article reports the first case of GPIBD15 caused by GPAA1 gene mutation in China and summarizes the genetic features, clinical features, diagnosis, and treatment of this disease, which provides a reference for the early diagnosis and treatment of GPIBD15.

Conclusion:The contents of artemisinin and arteannuin B among different <italic>A. annua</italic> germplasms were significantly different under the same culture environment， and the dominant factors affecting biosynthesis and accumulation of artemisinin and arteannuin B in <italic>A. annua</italic> may be the genetic background， suggesting that germplasm improvement is the key factor to improve the medicinal quality of <italic>A. annua</italic> in subsequent cultivation.

A Meta analysis on the effectiveness of multiple health education implementation forms on exercise behavior among college students / 中国学校卫生

Objective@#To compare the effectiveness of three forms of health education including classroom teaching, network teaching and after class tutoring on exercise behavior among college students.@*Methods@#A literature search was performed using web of science, PubMed, ScienceDirect, Scopus, Cochrane Library, and CNKI database on randomized controlled trials of health education intervention on exercise behavior among college students. Literature filtering, data extraction, and assessment of the risks of bias were conducted by two independent researchers using Stata 16.0 software based on traditional Meta analysis and network meta analysis.@*Results@#A total of 23 literatures were included. The results showed that health education courses could effectively increase the weekly exercise time of college students( SMD =0.29), exercise frequency ( SMD =0.25) and number of students participating in exercise( OR =1.33). Subgroup analysis revealed that the increase in classroom teaching and network teaching associated with increased weekly exercise time ( SMD =0.45, 0.36), exercise frequency ( SMD =0.22, 0.37) and exercise number ( OR =1.36, 1.26)(all P <0.05); The effect of after class tutoring on the time and frequency of weekly exercise was not statistically significant( P >0.05). Indirect comparison showed that the effects of classroom teaching and network teaching on weekly exercise time, and exercise frequency were superior to that of extracurricular counselling( P <0.05); There were no significant differences in the weekly exercise time, frequency and number of participants between the two groups( P >0.05). Based on SUCRA method and the effect size, health education in the form of classroom teaching may have the greatest effect on the weekly exercise time, frequency and the number of students participating in the exercise( SUCRA =91.5, 94.1, 87.1).@*Conclusion@#Health education in the form of classroom teaching and network teaching can positively influence exercise behavior of college students.It is suggested that health education courses should be carried out in college courses so as to better promote college students to participate in physical exercise.

A comparison of perioperative outcomes between extraperitoneal robotic single-port and multiport radical prostatectomy with the da Vinci Si Surgical System / 亚洲男科学杂志(英文版)

To evaluate outcomes between extraperitoneal robotic single-port radical prostatectomy (epR-spRP) and extraperitoneal robotic multiport radical prostatectomy (epR-mpRP) performed with the da Vinci Si Surgical System, comparison was performed between 30 single-port (SP group) and 26 multiport (MP group) cases. Comparisons included operative time, estimated blood loss (EBL), hospital stay, peritoneal violation, pain scores, scar satisfaction, continence, and erectile function. The median operation time and EBL were not different between the two groups. In the SP group, the median operation time of the first 10 patients was obviously longer than that of the latter 20 patients (P < 0.001). The median postoperative hospital stay in the SP group was shorter than that in the MP group (P < 0.001). The rate of peritoneal damage in the SP group was less than that in the MP group (P = 0.017). The pain score and overall need for pain medications in the SP group were lower than those in the MP group (P < 0.001 and P = 0.015, respectively). Patients in the SP group were more satisfied with their scars than those in the MP group 3 months postoperatively (P = 0.007). At 3 months, the cancer control, recovery of erectile function, and urinary continence rates were similar between the two groups. It is safe and feasible to perform epR-spRP using the da Vinci Si surgical system. Therefore, epR-spRP can be a treatment option for localized prostate cancer. Although epR-spRP still has a learning curve, it has advantages for postoperative pain and self-assessed cosmesis. In the absence of the single-port robotic surgery platform, we can still provide minimally invasive surgery for patients.

Objective: To screen out active ingredients, and predict the anti-cancer targets of Ligustri Lucidi Fructus-Astragali Radix based on the "herbs-active ingredient-action targets" network. Method: The traditional Chinese medicine (TCM) system pharmacology platform (TCMSP) was employed to screen out the active ingredients and putative targets of anti-cancer of glossy privet fruit and astragalus. DisGeNET database and Online Mendelian Inheritance in Man (OMIM database) were employed to predict the targets for treating cancer, and then "herbs-active ingredients-key targets" network was constructed by using Cytoscape software. The omicshare platform was employed to match the putative targets of ingredients and the targets for treating cancer. Finally, the protein interaction network of key targets was constructed by using String database, and the analysis of biological functions and pathways of them was carried out by using DAVID database. Result: Totally 33 drug active ingredients were screened out, involving a total of 203 targets, and 14 of them were related to cancer. These 14 key targets played an therapeutic role in treating cancer by regulating target proteins, such as ERBB2, AR, SRC, EGFR, ESR1, as well as proteoglycans in cancer, cancer pathways, microRNAs in cancer and other pathways. Conclusion: The therapeutic mechanism of Ligustri Lucidi Fructus-Astragali Radix reflects the multi-component, multi-target, and multi-pathway characteristics of TCMs, providing the scientific basis for further study and the material basis of Ligustri Lucidi Fructus-Astragali Radix against cancer.

Serum uric acid levels and hyperuricemia in patients with psoriasis: a hospital-based cross-sectional study

Abstract: A hospital-based cross-sectional study was performed, including 117 psoriatic patients and 117 controls matched for age, gender, and body mass index. Psoriatic patients had higher levels of serum uric acid (6.25 ± 1.62 vs 5.71 ± 1.35 mg/dl; P=0.019) and significantly greater prevalence of hyperuricemia (31.6% vs 16.2%; P=0.009) than individuals without psoriasis. Psoriatic patients had significantly higher serum uric acid than controls in subjects without metabolic syndrome. Multivariate logistic regression analysis showed that psoriasis can be a strong predictor of hyperuricemia (odds ratio 2.61; 95% confidence interval 1.34-5.00; P=0.004).

Pathogenic Mechanisms of the Focal Segmental Glomerulosclerosis and Its Role in the Progression of IgA Nephropathy / 中国医学科学院学报

Focal segmental glomerulosclerosis (FSGS),a common pathological change in kidney diseases,may be caused by primary factors or multiple secondary factors. Its pathogenic mechanism remains a hot topic in kidney disease research. FSGS-like pathologic changes are highly in IgA nephropathy. It has been speculated that FSGS in IgA nephropathy might be caused by hemodynamics changes,and podocyte injury,which,however,have not been well documented. Our current review focuses on the pathogenesis of secondary FSGS and its role in the progression of IgA nephropathy,with an attempt to provide more insights in the treatment of IgA nephropathy.

Focus on the hotspots of CRRT / 天津医药

With the progress of technology and the development of severe kidney medicine, continuous renal replacement therapy (CRRT) has been extended to kidney support and has been widely used for aiming to rapidly correct fatal complications of several life-threatening renal impairment (AKI). However, there are many controversies and problems, including the timing of initiating CRRT, the dosage of treatment and the choice of filter membrane material for different kinds of critically ill patients. The controversy and study of 60 years have not come to a unanimous conclusion, which reflects the critically clinical complexity. There is no "unchangeable (one size fits all)" treatment model, but rather a "patient-centered, individualized, precision CRRT" treatment. This article was to explore these three hotspots in order to provide more evidences for clinicians to perform rationalized, personalized and precise CRRT, and to make more patients benefit from CRRT.

Objective To study the effects and mechanisms of BuShenYangGuTang on proliferation and apoptosis of multiple myeloma cell line KM3. Methods The inhibitory effect of BuShenYangGuTang on cell proliferation was assessed by CCK-8. BuShenYangGuTang induced KM3 cell cycle arrest was analyzed by flow cytometry after propidium iodide staining. Flow cytometry was also used to analyze the cell apoptosis after Annexin V-FITC staining. The expressions of Bcl-2, Bax and NF-κB were determined by RT-qPCR and Western blot assay. Results BuShenYangGuTang inhibited the KM3 cell proliferation in a dose-dependent manner. The expression levels of Bcl-2 and NF-κB were decreased, the expression level of Bax was increased, and the cell cycle was arrested in G0 / G1 phase after treatment with BuShenYangGuTang. Conclusion BuShenYangGuTang could inhibit the proliferation, arrest cell cycle and induce the apoptosis in KM3 cells, which may be related to the abnormal expressions of Bcl-2, Bax and NF-κB.

Repalr of large-segmental femoral defects using lentivirus-mediated bone morphogenetic protein 2/bone marrow mesenchymal stem cells/demineralized bone matrix / 中国组织工程研究

BACKGROUND: Our research team has confirmed that compared to the adenoviral vector, transfection by lentiviral vector to rabbit bone marrow mesenchymal stem cells (BMSCs) is more effective that the expression of enhanced green fluorescent protein (EGFP)/bone morphogenetic protein 2 (BMP-2) can be persistent for a longer term. But further investigations are needed to explore whether BMSCs transfected with hBMP-2 through lentivirus combined with demineralized bone matrix (DBM) can promote bone defect repair. OBJECTIVE: To evaluate the effect of lentivirus-mediated hBMP-2/BMSCs/DBM (LV-hBMP-2/BMSCs/DBM) on the repair of large-segmental femoral defects and to explore the new treatments for large-segmental femoral defects. METHODS: Large-segmental bone defect models were made in the right femur of 48 New Zealand white rabbits by cutting the middle femoral bone and steel plate fixation. Then, animal models were randomly divided into four groups (n=12 per group) and implanted with nothing (control), DBM, hBMP-2/DBM, and LV-hBMP-2/BMSCs/DBM. Three rabbits from each group were sacrificed at 2, 4, 8 and 12 weeks after surgery to evaluate the repairing effect of femoral defects through hematoxylin-eosin staining, biomechanical analysis and radiological examination. RESULTS AND CONCLUSION: X-ray results revealed that osteotylus formed in all the four groups to different extents, and Lane - Sandhu X-ray scores were ranked as follows: control group < DBM group < hBMP-2/DBM group < LV-hBMP-2/BMSCs/DBM group (P < 0.05). Findings from the three-point bending test showed that the maximum load of the LV-hBMP-2/BMSCs/DBM group was significantly higher than that of the hBMP-2/DBM group, but is still lower than that of the normal femur at 8 and 12 weeks after modeling (P < 0.05). Hematoxylin-eosin staining results revealed that a few trabecular bones arranged disorderedly and a large amount of fibrous tissues in the control group; the DBM scaffold was basically degraded in the DBM group presenting with partially disordered trabecular bones and a large amount of fibrous tissues; the trabecular bones in the bone defect area were basically connected into line to start the shaping of the cortical bone, and recanalization of the medullary cavity was insignificant in the hBMP-2/DBM group; new cortical bone formed in the bone defect area and the medullary cavity was recanalized in the LV-hBMP-2/BMSCs/DBM group. These findings indicate that LV-hBMP-2/BMSCs/DBM can produce a large amount of calluses, promote formation of new cortical bone, and promote bone conduction, bone induction and osteogenesis after implantation into the bone defect; and this material has good repairing effect on large-segmental femoral defects of rabbits.
