Objective:To establish HPLC fingerprints of Aristolochia contorta and honey-processed Aristolochia contorta; To analyze the changes of chemical components before and after honey processing with multivariate statistics; To provide a reference for the study on the toxicity reduction of Aristolochia contorta.Methods:The fingerprints of 11 batches of Aristolochia contorta and honey-processed Aristolochia contorta were established through HPLC. Clustering analysis (HCA), principal component analysis (PCA), orthogonal partial least squares discriminant analysis (OPLS-DA) and independent sample t-test were used to compare the changes of chemical components of Aristolochia contorta before and after honey processing.Results:The results showed that there were 14 common peaks in the fingerprints of Aristolochia contorta and Aristolochia contorta. 7 common peaks were identified. Both HCA and PCA could clearly distinguish the samples of Aristolochia contorta before and after honey processing. OPLS-DA found and screened 7 differential markers, and the order of difference significance was peak 3 > peak 7 (7-hydroxy aristolochic acid A) > peak 5 (aristolochic acid C)> peak 8 (aristolochic acid D) > peak 6 > peak 2 (Magnolia alkaloid) > peak 14 (aristolochic acid Ⅰ). After honey processing, the content of chemical components represented by peaks 2, 3, 5, 6, 7, 8 and 14 decreased ( P<0.05). Conclusion:This method is simple and specific, which can be used for the fingerprint analysis of Aristolochia contorta and honey-processed Aristolochia contorta, and can effectively distinguish Aristolochia contorta and honey-processed Aristolochia contorta, and provide a reference for the processing research of toxicity reduction of Aristolochia contorta honey processing.

Objective:To evaluate the effectiveness and safety of treatment with Burosumab in pediatric X-linked hypophosphatemia (XLH) patients.Methods:In this retrospective case study, 4 children with pediatric XLH, who were treated with Burosumab in Beijing Children′s Hospital, Capital Medical University and Shandong Provincial Hospital affiliated to Shandong First Medical University from July 2022 to December 2023, were selected as the study objects. We collected and analyzed their clinical characteristics, biochemical indicators, imaging results, and treatment. The children were followed up every 3 months until December 2023, and the clinical outcomes and adverse drug reactions after treatment were evaluated.Results:Of the 4 patients, 3 were males and 1 was female; they were aged 6.7, 2.9, 2.1, and 2.3 years, respectively. Three patients had previously received treatment with phosphate supplements and active vitamins, but their wadding gait and lower limb deformities did not improve significantly, neither did their imaging changes of active richets. The initial dose of Burosumab in the 4 patients was 0.8 mg/kg, administered subcutaneously every 2 weeks, with a treatment course of 0.8-1.3 years. The fasting serum phosphorus and tubular maximum reabsorption of phosphate/glomerular filtration rate (TmP/GFR) of the 4 patients before treatment were 0.72, 0.95, 0.81, 0.66 mmol/L and 0.67, 0.85, 0.87, 0.61 mmol/L, respectively. At the last follow-up, the fasting serum phosphorus and TmP/GFR levels were significantly increased (0.96, 1.09, 1.09, 0.90 mmol/L, and 0.85, 0.79, 1.03, 0.98 mmol/L, respectively). Among them, only the TmP/GFR level (1.17 mmol/L) in case 2 achieved normal values at 3 months post-therapy, while the rest did not reach the normal range for children of the same age. After treatment, the alkaline phosphatase levels of all patients gradually decreased (the values were 461, 240, 423, and 237 U/L, respectively), and the ALP levels in cases 2 and 4 returned to normal at the last visit. Case 4 showed a slight increase in parathyroid hormone (PTH) levels after 9 months of treatment, while the PTH levels in the rest 3 cases remained normal. Case 1 underwent a 6-minute walking test, and the walking distance increased from 245 m to 570 m. Abnormal gait, lower limb deformity, and the severity of rickets in the 4 patients had all improved. No adverse drug reactions such as nephrocalcinosis, local skin injection reaction, hyperphosphatemia, or vitamin D deficiency were observed.Conclusion:Burosumab can improve clinical symptoms in children with XLH with a good safety profile.

Alzheimer′s disease (AD) is a degenerative neurodegenerative disease of the central nervous system. The disease is concealed. Patients often experienced several years or even more than ten years of course evolution from the beginning of pathological changes to clinical symptoms. Once entering the stage of dementia, there is no ideal drug to reverse the disease. In order to improve the efficiency of early diagnosis, the research on early biomarkers of the disease has become a hot topic in recent years. In addition to the Aβ and tau, microRNAs have been discovered as potential biomarkers of AD.

Objective: To investigate the oral health service demands and utilization among school-age children in Xiangfang district of Harbin, and to explore the related influencing factors. Methods: A total of 7 944 children aged 6-11 were investigated for oral health status through questionnaire survey in Xiangfang District, Harbin. Descriptive analysis, Chi-square test, nonparametric test and Logistic regression were used to analyze the oral health service demands and utilization of school-age children. Results: The rate of caries, unfilled caries, malocclusion and traumatic dental injuries were 89.7%, 60.7%, 59.3% and 12.5%, respectively. In the past 12 months, 53.8% of children had toothache. The rate of seeking medical treatment in stomatology department was 31.6%, with the primary reason being treatment (47.6%), while the rate of preventive dental treatment was 15.6%. Multivariate analysis showed that girls, father s education being high school or technical secondary school, father s education higher or equal to junior college, poor oral health evaluation, high score on oral knowledge and oral attitude, brushing teeth once a day, brushing teeth twice a day or more, having attended oral health courses, having toothache experience, having dental trauma experience, suffering from dental caries were more likely to visit the oral clinics (OR=1.11，1.17，1.50，0.80，1.07，1.21，1.60，2.27，1.28，1.49，1.54，1.67, P<0.05). Conclusion In Xiangfang District of Harbin, there is a large demand for oral health services for school-age children, however, both of the utilization rate and the preventive medical treatment rate is low. Many factors affect the utilization of oral health services for children. It is suggested that targeted measures should be taken to improve the utilization level of school-age children s health resources.

Objective: To investigate the prevalence and risk factors of non-alcoholic fatty liver disease(NAFLD) in patients with chronic hepatitis B(CHB) receiving antiviral treatment. Methods: The cross-sectional study included 3 477 cases with CHB who received antiviral therapy. The prevalence of NAFLD was investigated, and then the risk factors were screened and analyzed by stepwise regression method in CHB patients with NAFLD as the dependent variable and the related influencing factors as independent variables. Results: The prevalence of NAFLD was 24.1% in CHB patients who received antiviral therapy. After adjusting for age and gender, central obesity (OR: 7.44, 95%CI: 6.06 ~ 9.14), hypertension (OR: 1.74, 95%CI: 1.51 ~ 2.20), and triglyceride (OR: 1.52, 95%CI: 1.18 ~ 1.96) were positively associated with NAFLD, and cirrhosis was negatively associated with NAFLD (OR: 0.42, 95%CI: 0.34 ~ 0.53). Patients with long-term antiviral therapy had increased risk of NAFLD. Conclusion A significant proportion of CHB patients receiving antiviral therapy have suffered from NAFLD. Therefore, CHB patients receiving long-term antiviral treatment should pay more attention to the prevalence of NAFLD.

Objective To investigate the effects of different umbilical cord ligation methods on anemia and jaundice in preterm infants with a gestational age less than 32 weeks.Methods A total of 135 preterm infants with a gestational age less than 32 weeks were recruited and randomly divided into the umbilical cord milking group,the delayed cord clamping group and the immediate cord clamping group,with 45 cases in each group.Comparisons among three groups were performed on hemoglobin,hematocrit at 1 h and 1 week after birth,and bilirubin peak,total time of phototherapy,the incidence of anemia,pathologic jaundice as well as polycythemia before discharge.Results Finally 40 cases in the umbilical cord milking group,42 cases in the delayed cord clamping group and 38 cases in the immediate cord clamping group were recruited.Compared with the immediate cord clamping group,Hb(g/L)and hematocrit(％) levels were significantly higher in the umbilical cord milking group and the delayed cord clamping group(P＜0.05),the anemia rate was significantly lower in umbilical cord milking group and the delayed cord clamping group(P＜0.05).However,there were no statistical differences in Hb(g/L) and hematocrit(％) levels as well as ane mia rate between the umbilical cord milking group and the delayed cord clamping group (P＞0.05).There were no significant differences among three groups in bilirubin peak,total time of phototherapy and the incidence of pathologic jaundice as well as polycythemia.Conclusion Umbilical cord milking and delayed cord clamping can both reduce the anemia rate,but not increase the risk of pathological jaundice.Umbilical cord milking can be preferred method for preterm infants with a gestational age less than 32 weeks and asphyxia.

Objective: To investigate the serum lipidomic profile in patients with nonalcoholic fatty liver disease (NAFLD), and to analyze the lipid metabolism characteristics of NAFLD. Methods: The subjects were divided into control group (23 patients) and pathologically confirmed NAFLD group (42 patients), and ultra-high-performance liquid chromatography-tandem mass spectrometry was used to measure serum lipidomic metabolites. The partial least squares-discriminant analysis (PLS-DA) model was established to analyze the differences in lipid metabolism with reference to the univariate analysis. The t-test and Mann-Whitney U test were used for data analysis. Results: A total of 239 lipids were identified and qualitative and quantitative analyses were performed. The PLS-DA model (R2 = 0.753, Q2 = 0.456) and the univariate analysis showed that 77 lipids were metabolized differentially between the NAFLD group and the control group (VIP > 1, P < 0.05), including free fatty acid, phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol, lysophosphatidylcholine, lysophosphatidylinositol (LPI), choline plasmalogen (PlsCho), ethanolamine plasmalogen (PlsEtn), ceramide (Cer), sphingomyelin, and triglyceride (TG). Compared with the control group, the NAFLD group had significant increases in monounsaturated fatty acids (increased by 39%, t = -3.954, P < 0.05) and TGs (increased by 36%, Z = -2.662, P < 0.05), mainly TGs with low numbers of carbon atoms and unsaturated bonds, while there were reductions in TGs with high numbers of carbon atoms and unsaturated bonds. In addition, compared with the control group, the NAFLD group had significant increases in the levels of LPI (increased by 223%, t = -3.858, P < 0.05) and Cer (increased by 21%, t = -2.481, P < 0.05) and significant reductions in PlsCho (reduced by 18%, t = 3.184, P < 0.05) and PlsEtn (reduced by 20%, t = 2.363, P < 0.05). Conclusion There is a significant difference in lipid metabolism profile between NAFLD patients and healthy people, and a serum lipidomic analysis of NAFLD helps to further clarify the characteristics of lipid metabolism in patients with NAFLD.

OBJECTIVETo evaluate the changes in the renal function of patients with chronic hepatitis B (CHB) receiving adefovir dipivoxil (ADV) or telbivudine (L-DT) monotherapy.

METHODSThis retrospective analysis involved 101 patients with CHB and liver cirrhosis receiving either ADV or L-DT monotherapy for 52 weeks. Serum creatinine, estimates of glomerular filtration rate (eGFR), and the percentage of patients with eGFR≥90 ml·min(-1)·1.73 m(-2) at week 52 were compared with the baseline data between the two groups.

RESULTSThe mean changes of CR at week 52 from baseline were +0.05 mg/dl in ADV group and -0.12 mg/dl in L-DT group, showing a significant difference between the two groups (P=0.000). No patient was found to have an elevation of creatinine over 0.50 mg/dl. The median change of eGFR at week 52 from baseline differed significantly between ADV and L-DT groups (-4.09 vs+18.32 ml·min(-1)·1.73 m(-2), P=0.000). Ninety-two percent (12/13) of the patients with baseline eGFR<90 ml·min(-1)·1.73 m(-2) shifted to eGFR ≥90 ml·min(-1)·1.73 m(-2) after 52 weeks of L-DT treatment, as compared to 38% (3/8) in ADV group. The proportion of patients with eGFR≥90 ml·min(-1)·1.73 m(-2) in L-DT group increased from 76.36% (42/55) at baseline to 94.55% (52/55) at week 52, while that in ADV group decreased from 82.61% (38/46) at baseline to 78.26% (36/46). The constituent ratios of eGFR at different levels were similar at baseline (P=0.443) but significantly different at week 52 between the two groups (P=0.015).

CONCLUSIONL-DT treatment is associated with a renoprotective effect in patients with CHB, but the mechanism remains unclear.

OBJECTIVETo appraise the clinical efficacy, safety and compliance of the intervention of spleen-restoring decoction combined with dormancy hygiene education and the intervention of spleen-restoring decoction alone on sub-healthy insomnia of deficiency of both the heart and spleen pattern.

METHODStudy design took multi-centers, blind and randomized control trial, 107 participants with sub-healthy insomnia of deficiency of both the heart and spleen pattern were assigned to A group (52 cases) which was treated with the intervention of spleen-restoring decoction combined with dormancy hygiene education and B group (55 cases) which was treated with the intervention of spleen-restoring decoction single, compared by efficacy, PSQI score, CGI score, WHOQOL-BREF score and security.

RESULTThe efficacy of two group was 79.58%. There was no significant different between them. The PSQI scores before treatment was (11.80 +/- 2.08) and which afer treatment was (6.78 +/- 2.84) of A group. The PSQI scores before treatment was (11.61 +/- 2.00) and which afer treatment was (6.73 +/- 2.27) of B group. There was significant difference in PSQI scores both A group and B group after treatment (P < 0.01); the results of CGI score and WHOQOL-BREF score before and after measurement showed the same as PSQI. There were no significant difference between two groups in all scores after treatment and there was no interaction between time pots and treatment factors . Withdrawal reaction analysis: comparing CGI after withdraw 2 weeks and at the end of treatment course, there was no significant difference between two groups. The same result was in comparison among groups.

CONCLUSIONBoth the intervention of spleen-restoring decoction integrating with dormancy hygiene education and spleen-restoring decoction had obvious clinical efficacy on treating subhealthy insomnia of deficiency of both the heart and spleen pattern, and had high compliance and safety. The intervention of spleen-restoring decoction integrating with dormancy hygiene education showed no better clinical efficacy than spleen-restoring decoction did.
