ABSTRACT

Objective@#To explore the relationship between the ratio of dietary vitamin A (VitA) to body weight and hypertension among children, so as to provide a reference for blood pressure control through dietary nutritional interventions and childhood hypertension prevention.@*Methods@#Utilizing the baseline survey and followup sample data from the Healthy Children Cohort established in urban and rural areas of Chongqing from 2014 to 2019, structured quantitative dietary questionnaire and selfdesigned questionnaire were used to investigate the information of dietary intake and socioeconomic characteristics of 15 279 children, as well as blood pressure, height, weight measurement. The ratio of dietary VitA to body weight was divided into four groups based on quartiles [≤P25(Q1), >P25~P50(Q2), >P50~P75(Q3), >P75(Q4)]. Generalized linear regression models and Logistic regression models were used to analyze the correlation between ratio of dietary VitA to body weight with blood pressure levels and prevalence of hypertension.@*Results@#The results of the 2014 baseline survey indicated that, after adjusting for confounding factors such as demographic indicators and nutritional intake, significant differences were observed in systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial pressure (MAP) among different groups categorized by the ratio of dietary VitA to body weight (F=157.57, 44.71, 95.92, P<0.01). The baseline ratio of dietary VitA to body weight in children exhibited a negative correlation with DBP, SBP and MAP at baseline and in 2019[baseline: β(95%CI)=-0.65(-0.89--0.42), -0.22(-0.42--0.01), -0.36(-0.56--0.16); 2019: β(95%CI)=-0.77(-1.34--0.19), -0.62(-1.21--0.02), -0.77(-1.34--0.19), P<0.05]. Compared to Q1 group, the risk of hypertension decreased among children in Q4 at baseline and followup in 2019 [OR(95%CI)=0.63(0.49-0.81), 0.18(0.08-0.42), P<0.01].@*Conclusions@#The ratio of dietary VitA to body weight is significantly negatively correlated with blood pressure levels among children, and dietary VitA deficiency is an independent risk factor for hypertension among children. Measures should be taken to actively adjust childrens dietary nutrition and reduce the risk of childhood hypertension.

ABSTRACT

Inherited retinal diseases (IRDs) are the major cause of refractory blinding eye diseases, and gene replacement therapy has already made preliminary progress in the treatment of IRDs. For IRDs that cannot be treated by gene replacement therapy, gene editing provides an alternative therapeutic method. Strategies like disruption of pathogenic variants with or without gene augmentation therapy and precise repair of pathogenic variants can be applied for IRDs with various inheritance patterns and pathogenic variants. In animal models of retinitis pigmentosa, Usher syndrome, Leber congenital amaurosis, cone rod cell dystrophy, and other disorders, CRISPR/Cas9, base editing, and prime editing showed the potential to edit pathogenic variations in vivo, indicating a promising future for gene editing therapy of IRDs.

ABSTRACT

Capillary electrochromatography(CEC)plays a significant role in chiral separation via the double sepa-ration principle,partition coefficient difference between the two phases,and electroosmotic flow-driven separation.Given the distinct properties of the inner wall stationary phase(SP),the separation ability of each SP differs from one another.Particularly,it provides large room for promising applications of open tubular capillary electrochromatography(OT-CEC).We divided the OT-CEC SPs developed over the past four years into six types:ionic liquids,nanoparticle materials,microporous materials,biomaterials,non-nanopolymers,and others,to mainly introduce their characteristics in chiral drug separation.There also added a few classic SPs that occurred within ten years as supplements to enrich the features of each SP.Additionally,we discuss their applications in metabolomics,food,cosmetics,environment,and biology as analytes in addition to chiral drugs.OT-CEC plays an increasingly significant role in chiral separation and may promote the development of capillary electrophoresis(CE)combined with other instruments in recent years,such as CE with mass spectrometry(CE/MS)and CE with ultraviolet light detector(CE/UV).

ABSTRACT

Objective:To investigate the status quo and influencing factors of decision-making regret of surrogate decision makers (SDMs) in neurocritically ill patients.Methods:This study was a cross-sectional survey. A total of 110 critically ill patients admitted to Department of Neurosurgery, First Affiliated Hospital of Anhui University of Traditional Chinese Medicine from August 2021 to April 2022 were selected as the research objects by convenient sampling method. Different methods were adopted in the research including general information questionnaire, Chinese Version of Decision-Making Regret Assessment Scale, Disease-Related Knowledge Awareness Questionnaire, General Self-Efficacy Scale, Self-Rating Anxiety Scale, Self-Rating Depression Scale to conduct a questionnaire survey on SDMs in neurocritically ill patients. Multiple linear stepwise regression was used to analyze the influencing factors of decision-making regret in SDMs in neurocritically ill patients.Results:Among the 110 patients with severe neurological diseases, 50.0% (55/110) had no regret, 30.9% (34/110) had mild regret, and 19.1 (21/110) had moderate and severe regret. The results of univariate analysis showed that gender had a statistically significant effect on the score of SDMs decision regret in neurocritical patients ( t=6.57, P<0.05). The age, relationship with patients, education level, decision-making style, place of residence, and monthly income of the family had no effect on the score of regret in decision-making ( t=0.09-1.01, all P>0.05). The results of correlation analysis showed that the score of decision-making regret of SDMs in neurocritically ill patients was negatively correlated with the scores of disease-related knowledge and self-efficacy ( r=-0.342, -0.252, both P<0.05), and positively correlated with the scores of anxiety and depression ( r=0.403, 0.360, both P<0.05). The results of multiple linear regression showed that gender, disease-related knowledge, self-efficacy, anxiety and depression were important factors affecting the decision-making regret of SDMs in neurocritically ill patients ( t values were -3.37-4.31, all P<0.05). Conclusions:SDMs in neurocritically ill patients have a higher degree of decision-making regret, and gender, disease-related knowledge, self-efficacy, anxiety, depression are important influencing factors, suggesting that medical staff can alleviate the decision-making regret of SDMs through decision-making assistance interventions.

ABSTRACT

OBJECTIVE@#To analyze the efficacy of Biejiajian Pill (BJJP) on intestinal microbiota in patients with hepatitis B cirrhosis/liver fibrosis, and explore its relationship with liver fibrosis.@*METHODS@#This was a prospective, randomized double-blind controlled trial. Using the stratified block randomization method, 35 patients with hepatitis B liver cirrhosis/liver fibrosis were randomly assigned (1:1) to receive entecavir (0.5 mg/d) combined with BJJP (3 g/time, 3 times a day) or placebo (simulator as control, SC group, simulator 3 g/time, 3 times a day) for 48 weeks. Blood and stool samples were collected from patients at baseline and week 48 of treatment, respectively. Liver and renal functions as well as hematological indices were detected. Fecal samples were analyzed by 16S rDNA V3-V4 high-throughput sequencing, and intestinal microbiota changes in both groups before and after treatment were compared, and their correlations with liver fibrosis were analyzed.@*RESULTS@#Compared with the SC group, there was no significant difference in liver function, renal function and hematology indices in the BJJP group, however, the improvement rate of liver fibrosis was higher in the BJJP group (94.4% vs. 64.7%, P=0.041). Principal coordinate analysis (PCoA) based on weighted Unifrac distance showed significant differences in intestinal microbiota community diversity before and after BJJP treatment (P<0.01 and P=0.003), respectively. After 48 weeks' treatment, the abundance levels of beneficial bacteria (Bifidobacteria, Lactobacillus, Faecalibacterium and Blautia) increased, whereas the abundance levels of potential pathogenic bacteria, including Escherichia coli, Bacteroides, Ruminococcus, Parabacteroides and Prevotella decreased, among which Ruminococcus and Parabacteroides were significantly positively correlated with degree of liver fibrosis (r=0.34, P=0.04; r=0.38, P=0.02), respectively. The microbiota in the SC group did not change significantly throughout the whole process of treatment.@*CONCLUSION@#BJJP had a certain regulatory effect on intestinal microbiota of patients with hepatitis B cirrhosis/liver fibrosis (ChiCTR1800016801).

ABSTRACT

OBJECTIVE@#To identify and characterize read-through RNAs and read-through circular RNAs (rt-circ-HS) derived from transcriptional read-through hypoxia inducible factor 1α (HIF1α) and small nuclear RNA activating complex polypeptide 1 (SNAPC1) the two adjacent genes located on chromosome 14q23, in renal carcinoma cells and renal carcinoma tissues, and to study the effects of rt-circ-HS on biological behavior of renal carcinoma cells and on regulation of HIF1α.@*METHODS@#Reverse transcription-polymerase chain reaction (RT-PCR) and Sanger sequencing were used to examine expression of read-through RNAs HIF1α-SNAPC1 and rt-circ-HS in different tumor cells. Tissue microarrays of 437 different types of renal cell carcinoma (RCC) were constructed, and chromogenic in situ hybridization (ISH) was used to investigate expression of rt-circ-HS in different RCC types. Small interference RNA (siRNA) and artificial overexpression plasmids were designed to examine the effects of rt-circ-HS on 786-O and A498 renal carcinoma cell proliferation, migration and invasiveness by cell counting kit 8 (CCK8), EdU incorporation and Transwell cell migration and invasion assays. RT-PCR and Western blot were used to exa-mine expression of HIF1α and SNAPC1 RNA and proteins after interference of rt-circ-HS with siRNA, respectively. The binding of rt-circ-HS with microRNA 539 (miR-539), and miR-539 with HIF1α 3' untranslated region (3' UTR), and the effects of these interactions were investigated by dual luciferase reporter gene assays.@*RESULTS@#We discovered a novel 1 144 nt rt-circ-HS, which was derived from read-through RNA HIF1α-SNAPC1 and consisted of HIF1α exon 2-6 and SNAPC1 exon 2-4. Expression of rt-circ-HS was significantly upregulated in 786-O renal carcinoma cells. ISH showed that the overall positive expression rate of rt-circ-HS in RCC tissue samples was 67.5% (295/437), and the expression was different in different types of RCCs. Mechanistically, rt-circ-HS promoted renal carcinoma cell proliferation, migration and invasiveness by functioning as a competitive endogenous inhibitor of miR-539, which we found to be a potent post-transcriptional suppressor of HIF1α, thus promoting expression of HIF1α.@*CONCLUSION@#The novel rt-circ-HS is highly expressed in different types of RCCs and acts as a competitive endogenous inhibitor of miR-539 to promote expression of its parental gene HIF1α and thus the proliferation, migration and invasion of renal cancer cells.

ABSTRACT

Objective: To investigate the clinical efficacy of entecavir combined with Biejiajian pills and its influence on TCM syndrome scores during the treatment of chronic hepatitis B with hepatic fibrosis and blood stasis syndrome by prospective, randomized and controlled study. Methods: Patients with chronic hepatitis B with hepatic fibrosis and blood stasis syndrome were selected as the research subjects and randomly divided into a treatment group and a control group. Entecavir plus Biejiajian pills or entecavir plus a simulant of Biejiajian pills were given for 48 weeks. The changes in liver stiffness measurement (LSM) and TCM syndrome scores before and after treatment were compared between the two groups to analyze the correlation. The data between groups were analyzed by t-test/Wilcoxon rank sum test or χ(2) test. Pearson correlation coefficient was used to analyze the correlation between TCM syndrome scores and LSM values. Results: After 48 weeks of treatment, the LSM values of the two groups were significantly lower than those of the baseline (P < 0.001), liver fibrosis was significantly improved, and the LSM values of the treatment group were lower than those of the control group [(8.67 ± 4.60) kPa and (10.13 ± 4.43) kPa, t = -2.011, P = 0.049]. After 48 weeks of treatment, the TCM syndrome scores of the two groups were significantly reduced compared with the baseline (P < 0.001), and the clinical symptoms were significantly relieved, and the total effective rates of the improvement of the TCM syndrome scores in the two groups were 74.19% and 72.97%, respectively, but the differences between the groups were not statistically significant (χ(2) = 0.013, P = 0.910). Correlation analysis showed that there was no obvious trend between TCM syndrome scores and LSM values. There were no serious adverse reactions associated with the drug during the observation period of this study. Conclusion: Based on antiviral treatment with entecavir, regardless of whether it is combined with the Biejiajian pill, it can effectively reduce the LSM value, improve liver fibrosis, reduce TCM syndrome scores, and alleviate symptoms in patients with chronic hepatitis B with liver fibrosis and blood stasis syndrome. Compared with entecavir alone, the combined Biejia pill has greater efficacy in improving liver fibrosis and a favorable safety profile, meriting its implementation and widespread application.

ABSTRACT

Objective: To investigate the histological features and clinical manifestations in different types of cardiac amyloidosis to improve diagnostic accuracy. Methods: The histopathological features and clinical manifestations of 48 patients diagnosed with cardiac amyloidosis by Congo red stain and electron microscopy through endomyocardial biopsy were collected in West China Hospital of Sichuan University from January 2018 to December 2021. Immunohistochemical stains for immunoglobulin light chains (κ and λ) and transthyretin protein were carried out, and a review of literature was made. Results: The patients age ranged from 42 to 79 years (mean 56 years) and the male to female ratio was 1.1 to 1.0. The positive rate of endomyocardial biopsy was 97.9% (47/48), which was significantly higher than that of the abdominal wall fat (7/17). Congo red staining and electron microscopy were positive in 97.9% (47/48) and 93.5% (43/46), respectively. Immunohistochemical stains showed 32 cases (68.1%) were light chain type (AL-CA), including 31 cases of AL-λ type and 1 case of AL-κ type; 9 cases (19.1%) were transthyretin protein type (ATTR-CA); and 6 cases (12.8%) were not classified. There was no significant difference in the deposition pattern of amyloid between different types (P>0.05). Clinical data showed that ATTR-CA patients had less involvement of 2 or more organs and lower N-terminal pro-B-type natriuretic peptide (NT-proBNP) than the other type patients (P<0.05). The left ventricular stroke volume and right ventricular ejection fraction of ATTR-CA patients were better than the other patients (P<0.05). Follow-up data of 45 patients was obtained, and the overall mean survival time was 15.6±2.0 months. Univariate survival analysis showed that ATTR-CA patients had a better prognosis, while cardiac amyloidosis patients with higher cardiac function grade, NT-proBNP >6 000 ng/L, and troponin T >70 ng/L had a worse prognosis (P<0.05). Multivariate survival analysis showed that NT-proBNP and cardiac function grade were independent prognostic factors for cardiac amyloidosis patients. Conclusions: AL-λ is the most common type of cardiac amyloidosis in this group. Congo red staining combined with electron microscopy can significantly improve the diagnosis of cardiac amyloidosis. The clinical manifestations and prognosis of each type are different and can be classified based on immunostaining profile. However, there are still a few cases that cannot be typed; hence mass spectrometry is recommended if feasible.

ABSTRACT

Objective: To investigate the surgical indications and perioperative clinical outcomes of pelvic exenteration (PE) for locally advanced, recurrent pelvic malignancies and complex pelvic fistulas. Methods: This was a descriptive study.The indications for performing PE were: (1) locally advanced, recurrent pelvic malignancy or complex pelvic fistula diagnosed preoperatively by imaging and pathological examination of a biopsy; (2)preoperative agreement by a multi-disciplinary team that non-surgical and conventional surgical treatment had failed and PE was required; and (3) findings on intraoperative exploration confirming this conclusion.Contraindications to this surgical procedure comprised cardiac and respiratory dysfunction, poor nutritional status,and mental state too poor to tolerate the procedure.Clinical data of 141 patients who met the above criteria, had undergone PE in the Sixth Affiliated Hospital of Sun Yat-sen University from January 2018 to September 2022, had complete perioperative clinical data, and had given written informed consent to the procedure were collected,and the operation,relevant perioperative variables, postoperative pathological findings (curative resection), and early postoperative complications were analyzed. Results: Of the 141 included patients, 43 (30.5%) had primary malignancies, 61 (43.3%) recurrent malignancies, 28 (19.9%) complex fistulas after radical resection of malignancies,and nine (6.4%)complex fistulas caused by benign disease. There were 79 cases (56.0%) of gastrointestinal tumors, 30 cases (21.3%) of reproductive tumors, 16 cases (11.3%) of urinary tumors, and 7 cases (5.0%) of other tumors such mesenchymal tissue tumors. Among the 104 patients with primary and recurrent malignancies, 15 patients with severe complications of pelvic perineum of advanced tumors were planned to undergo palliative PE surgery for symptom relief after preoperative assessment of multidisciplinary team; the other 89 patients were evaluated for radical PE surgery. All surgeries were successfully completed. Total PE was performed on 73 patients (51.8%),anterior PE on 22 (15.6%),and posterior PE in 46 (32.6%). The median operative time was 576 (453,679) minutes, median intraoperative blood loss 500 (200, 1 200) ml, and median hospital stay 17 (13.0,30.5)days.There were no intraoperative deaths. Of the 89 patients evaluated for radical PE surgery, the radical R0 resection was achieved in 64 (71.9%) of them, R1 resection in 23 (25.8%), and R2 resection in two (2.2%). One or more postoperative complications occurred in 85 cases (60.3%), 32 (22.7%)of which were Clavien-Dindo grade III and above.One patient (0.7%)died during the perioperative period. Conclusion: PE is a valid option for treating locally advanced or recurrent pelvic malignancies and complex pelvic fistulas.

ABSTRACT

Objective To study the expression of selenoprotein genes in human immunodeficiency virus(HIV)infection and its mother-to-child transmission,so as to provide a theoretical basis for the prevention,diagnosis,and treatment of acquired immunodeficiency syndrome.Methods The dataset GSE4124 was downloaded from the Gene Expression Omnibus(GEO).Two groups of HIV-positive mothers(n=25)and HIV-negative mothers(n=20)were designed.HIV-positive mothers included a subset of transmitter(TR)mothers(n=11)and non-transmitter(NTR)mothers(n=14).Then,t-test was carried out to compare the expression levels of selenoprotein genes between the four groups(HIV-positive vs. HIV-negative,NTR vs. HIV-negative,TR vs. HIV-negative,TR vs. NTR).Univariate and multivariate Logistic regression were adopted to analyze the effects of differentially expressed genes on HIV infection and mother-to-child transmission.R software was used to establish a nomogram prediction model and evaluate the model performance.Results Compared with the HIV-negative group,HIV-positive,NTR,and TR groups had 8,5 and 8 down-regulated selenoprotein genes,respectively.Compared with the NTR group,the TR group had 4 down-regulated selenoprotein genes.Univariate Logistic regression analysis showed that abnormally high expression of GPX1,GPX3,GPX4,TXNRD1,TXNRD3,and SEPHS2 affected HIV infection and had no effect on mother-to-child transmission.The multivariate Logistic regression analysis showed that the abnormally high expression of TXNRD3(OR=0.032,95%CI=0.002-0.607,P=0.022)was positively correlated with HIV infection.As for the nomogram prediction model,the area under the receiver-operating characteristic curve for 1-year survival of HIV-infected patients was 0.840(95%CI=0.690-1.000),and that for 3-year survival of HIV-infected patients was 0.870(95%CI=0.730-1.000).Conclusions Multiple selenoprotein genes with down-regulated expression levels were involved in the regulation of HIV infection and mother-to-child transmission.The abnormal high expression of TXNRD3 was positively correlated with HIV infection.The findings provide new ideas for the prevention,diagnosis,and treatment of acquired immunodeficiency syndrome.

ABSTRACT

A randomized, double-blind, placebo-controlled, multi-center phase Ⅱ clinical trial design was used in this study to recruit subjects who were in line with the syndrome of excess heat and fire toxin, and were diagnosed as recurrent oral ulcers, gingivitis, and acute pharyngitis. A total of 240 cases were included and randomly divided into a placebo group and a Huanglian Jiedu Pills group. The clinical efficacy of Huanglian Jiedu Pills in treating the syndrome of excess heat and fire toxin was evaluated by using the traditional Chinese medicine(TCM) syndrome scale. Enzyme-linked immunosorbent assay(ELISA) was used to determine and evaluate the levels of adenosine triphosphate(ATP), 4-hydroxynonenal(4-HNE), and adrenocorticotropic hormone(ACTH) in plasma of the two groups before and after administration and to predict their application value as clinical biomarkers. The results showed that the disappearance rate of main symptoms in the Huanglian Jiedu Pills group was 69.17%, and that in the placebo group was 50.83%. The comparison between the Huanglian Jiedu Pills group and the placebo group showed that 4-HNE before and after administration was statistically significant(P<0.05). The content of 4-HNE in the Huanglian Jiedu Pills group decreased significantly after administration(P<0.05), but that in the placebo group had no statistical significance and showed an upward trend. After administration, the content of ATP in both Huanglian Jiedu Pills group and placebo group decreased significantly(P<0.05), indicating that the energy metabolism disorder was significantly improved after administration of Huanglian Jiedu Pills and the body's self-healing ability also alleviated the increase in ATP level caused by the syndrome of excess heat and fire toxin to a certain extent. ACTH in both Huanglian Jiedu Pills group and placebo group decreased significantly after administration(P<0.05). It is concluded that Huanglian Jiedu Pills has a significant clinical effect, and can significantly improve the abnormal levels of ATP and 4-HNE in plasma caused by the syndrome of excess heat and fire toxin, which are speculated to be the effective clinical biomarkers for Huanglian Jiedu Pills to treat the syndrome of excess heat and fire toxin.

ABSTRACT

Objective:To explore the risk factors of hypotension in patients with hemodialysis-related superior vena cava diseases.Methods:This was a retrospective cohort study. The maintenance hemodialysis patients diagnosed as superior vena cava stenosis ≥50% or occlusion in West China Hospital of Sichuan University from January 1, 2019 to March 31, 2022 were selected. The patients were divided into hypotensive group and non-hypotensive group according to the occurrence of hypotension during non-dialysis period. The differences of general clinical data, cardiac ultrasound parameters and blood biochemical indexes between the two groups were compared. Multivariate logistic regression model was used to analyze the risk factors of hypotension in patients with hemodialysis-related superior vena cava lesions.Results:A total of 202 patients with hemodialysis-related superior vena cava lesions were included, of whom 84 patients (41.6%) developed hypotension during non-dialysis. Compared with the non-hypotensive group, patients in the hypotensive group had longer dialysis age ( Z=2.093, P=0.036), shorter left atrial diameter ( t=2.316, P=0.022), lower aortic valve orifice flow rate ( t=3.702, P=0.001) and serum calcium ( t=2.320, P=0.021), thicker left ventricular posterior wall ( t=3.042, P=0.003), lower proportions of hypertension history ( χ2=9.125, P=0.003), and higher proportion of residual superior vena cava ≤30% or occlusion ( χ2=8.940, P=0.003) and azygous vein opening ( χ2=11.067, P=0.001). Multivariate logistic regression analysis results showed that no history of hypertension ( OR=0.383, 95% CI 0.156-0.943, P=0.037), slow aortic valve orifice flow ( OR=0.207, 95% CI 0.062-0.695, P=0.011) and low blood calcium ( OR=0.236, 95% CI 0.066-0.841, P=0.026) were the independent influencing factors of hypotension in patients with hemodialysis-related superior vena cava diseases. Conclusions:Hemodialysis patients with severe stenosis or occlusion of the superior vena cava during non-dialysis have a higher risk of hypotension. No history of hypertension, slow aortic valve orifice flow, and low blood calcium are the independent risk factors of hypotension in patients with hemodialysis-related superior vena cava diseases.

ABSTRACT

Chinese medicines of Doukou includes Amomi Fructus Rotundus, Alpiniae Katsumadai Semen, Galangae Fructus and Myristicae Semen. They have a long medicinal history and are also commonly used in cooking and seasoning. Due to the similar names and limited to the traffic conditions in ancient times, the records of Doukou in ancient literature are often confused with many plants in the same family, and there are still many kinds of confused products. In order to promote the development of famous classical formulas containing the medicinal materials, the ancient literature of Doukou in the past dynasties was comprehensively combed from the aspects of name, origin, genuine area, medicinal parts, harvesting and processing and processing methods. It has been found that the basic original plants of Amomi Fructus Rotundus are Amomum kravanh and A. compactum, the original plant of Alpiniae Katsumadai Semen is Alpinia katsumadai and it often confused with Tsaoko Fructus. The main source of Galangae Fructus recorded in the ancient materia medica is the fruit of A. officinarum, while the 2020 edition of Chinese Pharmacopoeia stipulates that the original plant is A. galanga. Myristica fragrans is the original plant of Myristicae Semen. It was found that except M. fragrans, the other three kinds of medicinal origin of Doukou had changed, there are many other plants confused with each other. The four kinds of Doukou are produced in Southeast China and Southeast Asia, and most of Amomi Fructus Rotundus and Myristicae Semen are imported. The Chinese medicines of Doukou have clear medicinal parts and simple processing methods, the main methods in the past dynasties are cleaning, stir frying and simmering, and the processed products are selected according to the needs of different diseases. It is suggested to use the dry mature seeds of A. katsumadai in Houpo Wenzhongtang, which is from Guangxi, Guangdong, Hainan, Fujian and Yunnan and so on, among which Wanning in Hainan province is genuine producing area. The fruits should be harvested in summer and autumn, and dried to 90% dry in the sun, or slightly scalded with water and dried to half dry in the sun, and removed the peel, taken out the seed group, dried in the sun and then be used as medicine.

ABSTRACT

ObjectiveTo retrospectively analyze the clinical data of 52 patients with coronavirus disease-2019 (COVID-19) and explore the clinical efficacy of modified Sanxiaoyin on mild/moderate COVID-19 patients. MethodThe propensity score matching method was used to collect the clinical data of mild or moderate COVID-19 patients enrolled in the designated hospital of the Second Hospital of Jingzhou from December 2019 to May 2020. A total of 26 eligible patients who were treated with modified Sanxiaoyin were included in the observation group, and the 26 patients treated with conventional method were the regarded as the control. The disappearance of clinical symptoms, disappearance time of main symptoms, efficacy on traditional Chinese medicine (TCM) symptoms, hospitalization duration, laboratory test indicators, and CT imaging changes in the two groups were compared. ResultThe general data in the two groups were insignificantly different and thus they were comparable. After 7 days of treatment, the disappearance rate of fever, cough, fatigue, dry throat, anorexia, poor mental state, and poor sleep quality in the observation group was higher than that in the control group (P<0.05), and the difference in the disappearance rate of expectoration and chest distress was insignificant. For the cases with the disappearance of symptoms, the main symptoms (fever, cough, fatigue, dry throat, anorexia, chest distress) disappeared earlier in the observation group than in the control group (P<0.01). After 7 days of treatment, the scores of the TCM symptom scale of both groups decreased (P<0.01), and the decrease of the observation group was larger that of the control group (P<0.01). All patients in the two groups were cured and discharged. The average hospitalization duration in the observation group [(12.79±2.68) d] was shorter than that in the control group [(15.27±3.11) d] (P<0.01). The effective rate in the observation group (92.31%, 24/26) was higher than that in the control group (76.92%, 20/26) . After 7 days of treatment, the lymphocyte (LYM) count increased (P<0.05), and white blood cell (WBC) count and neutrophil (NEUT) count decreased insignificantly in the two groups. Moreover, levels of C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and procalcitonin (PCT) reduced in the two groups after treatment (P<0.01) and the reduction in the observation group was larger than that in the control group (P<0.01). Through 7 days of treatment, the total effective rate on pulmonary shadow in the observation group (90.00%, 18/20) was higher than that in the control group (77.27%, 17/22) (P>0.05) and the improvement of lung shadow in the observation group was better than that in the control group (P<0.01). ConclusionModified Sanxiaoyin can significantly alleviate fever, cough, fatigue, anorexia, chest distress, poor sleep quality, and other symptoms of patients with mild or moderate COVID-19, improve biochemical indicators, and promote the recovery of lung function. This paper provides clinical evidence for the application of modified Sanxiaoyin in the treatment of mild or moderate COVID-19.

ABSTRACT

OBJECTIVES@#To investigate the genetic polymorphism of InDel loci in SifalnDel 45plex system in the Han population in Jiangsu Province and the Mongolian population in Inner Mongolia, and to evaluate the effectiveness of the system in forensic medicine.@*METHODS@#SifaInDel 45plex system was used for genotyping in blood samples of 398 unrelated individuals from the above two populations, and allele frequencies and population genetic parameters of the two populations were calculated respectively. Eight intercontinental populations in the gnomAD database were used as reference populations. The genetic distances between the two studied populations and eight reference populations were calculated based on the allele frequencies of 27 autosomal-InDels (A-InDels). The phylogenetic trees and multidimensional scaling (MDS) analysis diagrams were constructed accordingly.@*RESULTS@#Among two studied populations, the 27 A-InDels and 16 X-InDels showed no linkage disequilibrium between each other and the allele frequency distributions were in Hardy-Weinberg equilibrium. The CDP of the 27 A-InDels in two studied populations were all higher than 0.999 999 999 9, and the CPEtrio were all less than 0.999 9. The CDP of the 16 X-InDels in Han in Jiangsu and Mongolian in Inner Mongolia female and male samples were 0.999 997 962, 0.999 998 389, and 0.999 818 940, 0.999 856 063, respectively. The CMECtrio were all less than 0.999 9. The results of population genetics showed that the Jiangsu Han nationality, Inner Mongolia Mongolian nationality and East Asian population clustered into one branch, showing closer genetic relationship. The other 7 intercontinental populations clustered into another group. And the above 3 populations displayed distant genetic relationships with the other 7 intercontinental populations.@*CONCLUSIONS@#The InDels in the SifaInDel 45plex system have good genetic polymorphism in the two studied populations, which can be used for forensic individual identification or as an effective complement for paternity identification, and to distinguish different intercontinental populations.

ABSTRACT

OBJECTIVES@#To study the genetic polymorphism and population genetic parameters of 16 X-STR loci in Xinjiang Uygur population.@*METHODS@#The Goldeneye® DNA identification system 17X was used to amplify 16 X-STR loci in 502 unrelated individuals (251 females and 251 males). The amplified products were detected by 3130xl genetic analyzer. Allele frequencies and population genetic parameters were analyzed statistically. The genetic distances between Uygur and other 8 populations were calculated. Multidimensional scaling and phylogenetic tree were constructed based on genetic distance.@*RESULTS@#In the 16 X-STR loci, a total of 67 alleles were detected in 502 Xinjiang Uygur unrelated individuals. The allele frequencies ranged from 0.001 3 to 0.572 4. PIC ranged from 0.568 8 to 0.855 3. The cumulative discrimination power in females and males were 0.999 999 999 999 999 and 0.999 999 999 743 071, respectively. The cumulative mean paternity exclusion chance in trios and in duos were 0.999 999 997 791 859 and 0.999 998 989 000 730, respectively. The genetic distance between Uygur population and Kazakh population was closer, and the genetic distance between Uygur and Han population was farther.@*CONCLUSIONS@#The 16 X-STR loci are highly polymorphic and suitable for identification in Uygur population, which can provide a powerful supplement for the study of individual identification, paternity identification and population genetics.

ABSTRACT

OBJECTIVES@#To estimate the system efficiency of uncle-nephew relationship identification by increasing STR markers and adding reference samples based on the test results of simulated data and real samples, so as to provide references for selecting the appropriate number of STRs and reference samples for uncle-nephew relationship identification.@*METHODS@#Five common models of uncle-nephew relationship identification were constructed by adding different reference samples. In each model, the likelihood ratio (LR) for 10 000 pairs of uncle-nephew relationships and 10 000 pairs of unrelated individuals were simulated by detecting 19, 39 or 55 STRs, and the system efficiency at different thresholds was simulated. The samples of the Han population in Zhejiang were collected, and 55 autosomal STRs were obtained by using SiFaSTRTM 23plex kit, Goldeneye® DNA ID 22NC kit and AGCU 21+1 PCR amplification kit. When 19, 39 and 55 STRs were detected, the LR of each model and system efficiency under different thresholds were calculated and compared with the simulation results.@*RESULTS@#Under the same detection system, the calculated results of simulated data and corresponding true samples were basically consistent. In the same model, there was a positive correlation between the system efficiency of uncle-nephew relationship identification and the number of STRs detected. Moreover, the system efficiency of introducing relatives was higher than identifying only two individuals. The order of preference for the introduction of relatives was the full sibling (or mother) of the uncle and the full sibling (or mother) of the nephew.@*CONCLUSIONS@#The system efficiency of uncle-nephew relationship identification could be improved by increasing the number of STRs and introducing known relatives, which would provide the basis for selecting the most appropriate detection system and reference individuals in actual cases.

ABSTRACT

Objective@#To investigate the factors affecting drug-induced liver injury among patients with pulmonary tuberculosis in Ningbo City from 2015 to 2019, so as to provide insights into the prevention of drug-induced liver injury.@*Methods@#Demographic features, presence of drug-induced liver injury, and disease history prior to anti-tuberculosis therapy were captured from patients with pulmonary tuberculosis in Ningbo City from 2015 to 2019 through the Tuberculosis Management Information System of the Chinese Disease Control and Prevention Information System and Ningbo Regional Diagnosis and Treatment Information Platform. Factors affecting drug-induced liver injury was identified using the multivariable logistic regression analysis.@*Results@#A total of 9 397 patients with pulmonary tuberculosis were enrolled, among whom 66.43% ( 6 242 case ) were male, 65.89% ( 6 192 cases ) were at ages of <60 years, and 92.35% ( 8 678 cases ) were treatment-naïve. There were 1 425 patients with drug-induced liver injury (15.16% incidence), including 729 cases with grade 1 (51.16%), 24 cases with grade 2 (1.68%), 7 cases with grade 3 (0.49%), 7 cases with grade 4 ( 0.49% ), and 658 cases with ungraded drug-induced liver injury ( 46.18% ). The median duration between drug administration and development of drug-induced liver injury was 24 ( interquartile range, 44 ) days. Multivariable logistic regression analysis identified treatment-naïve ( OR=1.464, 95%CI: 1.153-1.859 ) and history of liver disease ( OR=2.001, 95%CI: 1.709-2.342) as risk factors for drug-induced liver injury in patients with pulmonary tuberculosis.@*Conclusion@#The incidence of drug-induced liver injury was 15.16% among pulmonary tuberculosis patients in Ningbo City from 2015 to 2019. Treatment-naïve and a history of liver disease are associated with drug-induced liver injury among patients with pulmonary tuberculosis.
