Objective: To construct a prediction model for preterm birth risk among pregnant women, so as to provide the reference for screening high-risk population and preventing preterm birth. Methods: Pregnant women who received antenatal examination and delivered at the Women's Hospital, School of Medicine, Zhejiang University from January 1 to December 31, 2019 were selected as the study subjects, among them, 80% were included in the modeling group, and 20% were included in the validation group. Demographic and clinical information were collected. A multivariable logistic regression model was used to analyze the predictive factors of preterm birth risk in the modeling group, and a preterm birth risk prediction model was established based on the OR values of predictive factors. The model was validated with the data from the validation group. The Youden index was used to determine the critical score for predicting preterm birth risk. The prediction performance of the model was evaluated using the receiver operating characteristic (ROC) curve. Results: A total of 15 197 pregnant women were surveyed, including 12 131 pregnant women in the observation group and 3 066 pregnant women in the validation group. There was no statistically significant difference in age, education level and gravidity between the two groups of pregnant women (all P<0.05). Multivariable logistic regression analysis identified the number of pregnancies, education level, place of residence, hypertension, diabetes, history of preterm birth, twin-pregnancy, placenta praevia, and gestational hypertension as risk prediction factors for preterm birth risk among pregnant women. The risk score system for preterm birth was established as follows: >2 pregnancies (2 points), high school education or below (4 points), college degree or above (-4 points), rural residence (5 points), hypertension (7 points), diabetes (11 points), history of preterm birth (11 points), twin-pregnancy (28 points), placenta previa (19 points), and gestational hypertension (12 points). The total score of the preterm birth risk scoring system ranged from -4 to 99 points. When the critical score was 8 points, the Youden index was the highest at 0.480, with an area under the ROC curve of 0.749 (95%CI: 0.732-0.767), a sensitivity of 0.610, and a specificity of 0.886, indicating good prediction performance of the model. Conclusion The preterm birth risk prediction model established in this study based on demographic and clinical characteristics of pregnant women can effectively predict the risk of preterm birth among pregnant women.

Objective: To analyze the trends in disease burden of tuberculosis among children under 5 years of age in China from 1990 to 2021, so as to provide insights for future tuberculosis control measures among children in China. Methods: Based on the Global Burden of Disease (GBD) 2021 datasets, the incidence, prevalence, mortality and disability adjusted life year(DALY) of tuberculosis of children under 5 years of age in China and globally were collected from 1990 to 2021. The incidence, prevalence, mortality and DALY rate of tuberculosis were compared by genders and types. In addition,the annual percent change(APC) and the average annual percent change(AAPC) of children s tuberculosis burden in China and globally from 1990 to 2021 were calculated by using the Joinpoint regression model, and the changing trends were analyzed. Results: The numbers of incident, prevalent and dead tuberculosis cases were 9 700, 8 477 800 and 200 among children under 5 years of age in China in 2021, and the DALY due to tuberculosis were 27 100 person years. There were significant reductions in incidence, prevalence, mortality and DALY rate of tuberculosis among children under 5 years of age in China ( AAPC =-5.45%, -1.14%, -12.37%, -11.34 %) and globally( AAPC =-2.38%, -1.41%, -4.66%, -4.56%), and the reductions in the incidence, mortality and DALY rate were more significant in China than globally ( P <0.05).In 1992 and later, the numbers of incident, prevalent and dead tuberculosis cases and the DALY of tuberculosis were higher among male than among female. In addition, the disease burden of drug susceptible tuberculosis appeared a tendency of downward in China from 1990 to 2021, while the incidence and prevalence of extensively drug resistant tuberculosis rose since 2015. Conclusions The disease burden of tuberculosis remarkably reduced among children under 5 years of age in China from 1990 to 2021. However, the burden of disease due to multidrug resistant tuberculosis appeared an upward trend recently. Increased attention is required to be paid to the prevention and control of tuberculosis among children and improved diagnosis and treatment of drug resistant tuberculosis are recommended.

Objective To establish a rat model of hyperuricemic nephropathy(HN)using a multifactorial induction method of potassium oxazinate combined with adenine and yeast feed to observe the intervention effect of Qiling granules(QLG).Methods Fifty-eight SPF-grade male SD rats were selected,and 10 rats were randomly allocated to the normal control(NC)group.The remaining rats were induced by multiple factors to establish HN rat models.After 2 weeks of modeling,submandibular blood samples were taken to detect serum UA,CREA,BUN,TG,and TC.Forty HN rats with bleeding clearance UA and body weight close to the mean were selected.They were randomly divided into a model(M)group,QLG low dose(QLG-L)groups,QLG high dose(QLG-H)group,and a positive control(PC)group,with 10 rats in each group,using a stratified randomization method.Each group was given corresponding drugs by gavage daily,and after continuous administration for 4 weeks,submandibular blood samples were taken to detect serum UA,CREA,BUN,TG,and TC.After euthanasia of the rats,liver tissue was taken to detect XOD and ADA activity.Renal tissue was taken for HE and Gomori hexamine silver staining,and the protein expression of GLUT9,OAT1,VCAM-1,and TGF-β in the kidneys was observed using immunohistochemistry and Western blot method.Results Compared with the NC group,the M group's serum levels of UA,CREA,BUN,TC,and TG,as well as liver XOD and ADA activities,were significantly increased(P＜0.01).The renal tissue of the model rats showed significant pathological changes.The area of renal tubules positive for urate and the expression of GLUT9,VCAM-1,and TGF-β proteins in the kidneys were significantly increased(P＜0.01,P＜0.05),while the expression of OAT1 was significantly reduced(P＜0.01).Compared with the M group,each treatment group showed significantly reduced serum UA levels,liver XOD,ADA activity,and renal VCAM-1 protein expression(P＜0.01,P＜0.05).The serum CREA and BUN levels and renal TGF-β protein expression of rats in the QLG-L group were significantly reduced(P＜0.05,P＜0.01).The serum CREA and BUN levels and renal GLUT9 protein expression of rats in the QLG-H group were also significantly reduced(P＜0.01,P＜0.05).The urate deposition and renal injury caused by each treatment were reduced to varying degrees,but there were no significant differences among groups(P＞0.05).Conclusions A stable HN rat model can be induced by gavage of potassium oxyzinate and adenine in combination with yeast feed.QLG can effectively treat HN by improving UA metabolic disorders,reducing the renal inflammation and urate deposition that cause renal damage in HN model rats.Its mechanism of action is related to a reduction in serum UA,CREA,BUN,and TG levels;liver XOD and ADA activities;and the expression of GLUT9,OAT1,VCAM-1,and TGF-β proteins in the kidneys.

Objective:To investigate the correlation between complement C3 and urine protein level and proteinuria remission status in patients with primary membranous nephropathy (PMN), and better guide individualized clinical treatment.Methods:It was a single-center retrospective study. The clinical data of PMN patients who underwent renal biopsy in the First Affiliated Hospital of Nanjing Medical University from January 2017 to June 2022 were collected. Patients with 24 h urinary protein ≥ 3.5 g were followed up after receiving standard treatment, and the last outpatient or inpatient review was used as the end point of follow-up. 24 h urine protein was collected to evaluate the remission status of proteinuria. Kaplan-Meier method was used to analyze the correlation between serum and renal complements and proteinuria remission. Cox regression analysis method was used to analyze the correlation between serum C3 level and renal tissue C3 deposition and proteinuria remission.Results:This study included 507 PMN patients with 312 (61.54%) males, aged 54 (43, 64) years old. Compared with 24 h urinary protein < 3.5 g group, proportion of males ( χ2=22.479, P<0.001), age ( Z=-2.521, P=0.012), systolic blood pressure ( Z=-4.148, P<0.001), diastolic blood pressure ( Z=-4.084, P<0.001), serum anti-phospholipase A2 receptor (PLA2R) antibody titer ( Z=-7.019, P<0.001), total cholesterol ( Z=-8.796, P<0.001), triglyceride ( Z=-6.158, P<0.001), low density lipoprotein cholesterol ( Z=-8.716, P<0.001), serum creatinine ( Z=-7.368, P<0.001), serum C3 ( Z=-3.663, P<0.001), serum C4 ( Z=-6.560, P<0.001), proportion of glucocorticoid use ( χ2=116.417, P<0.001) and proportion of immunosuppressant use ( χ2=53.839, P<0.001) were all higher, while serum albumin ( Z=12.518, P<0.001), estimated glomerular filtration rate ( Z=6.345, P<0.001) and serum IgG ( Z=7.321, P<0.001) were all lower in 24 h urinary protein ≥3.5 g group. There were 268 patients included in the follow-up cohort with baseline 24 h urinary protein of 7.15 (5.14, 10.24) g, serum anti-PLA2R antibody titer of 61.44 (14.35, 193.24) RU/ml, serum C3 of 1.005 (0.864, 1.150) g/L, and serum C4 of 0.260 (0.214, 0.317) g/L. Kaplan-Meier survival curve showed that the incomplete remission rate of proteinuria in serum C3 > 1.005 g/L group was lower than that in serum C3 ≤ 1.005 g/L group (log-rank χ2=4.757, P=0.029). There was no significant difference in the incomplete remission rate of proteinuria between serum C4 ≤ 0.260 g/L group and serum C4 > 0.260 g/L group (log-rank χ2=3.543, P=0.060). Renal C1q (log-rank χ2=0.167, P=0.683) and C4 (log-rank χ2=1.927, P=0.165) deposition had no significant effects on proteinuria remission in PMN patients. The incomplete remission rate of proteinuria in patients with renal C3 deposition was higher than that in patients without renal C3 deposition (log-rank χ2=7.018, P=0.008). Univariate Cox regression analysis showed that serum C3 level and C3 deposition in renal tissues were influencing factors of incomplete remission of proteinuria (both P<0.05), while adjusting for gender, age, mean arterial pressure, serum anti-PLA2R antibody, serum albumin and 24 h urinary protein, serum C3 ≤ 1.005 g/L ( HR=1.374, 95% CI 1.021-1.849, P=0.036), C3 deposition in renal tissues ( HR=1.949, 95% CI 1.098-3.460, P=0.023), and serum C3 ≤ 1.005 g/L combined with C3 deposition in renal tissues ( HR=1.472, 95% CI 1.093-1.983, P=0.011) were independent influencing factors of incomplete remission of proteinuria. Conclusions:The serum C3 level and C3 deposition in renal tissues are closely related to urinary protein level and proteinuria remission status in PMN patients. The patients with higher urinary protein have higher serum C3. For patients with massive proteinuria, serum C3 ≤ 1.005 g/L, C3 deposition in renal tissues, serum C3 ≤ 1.005 g/L combined with C3 deposition in renal tissues are independent risk factors of incomplete remission of proteinuria.

In order to guarantee the quality of traditional Chinese medicines (TCMs), the crystallization transformation of complex extracts of TCMs and the influence of solid form on their physicochemical properties were studied.The extract of total flavonoids from Pueraria lobata was taken as a model.Crystallization transformation happened when lofting under different conditions, and the intrinsic dissolution tests were carried out.It was found that humidity was the key factor to induce crystallization of total flavonoids from Pueraria lobata.The greater the wettability was, the more the crystallization was.The dissolution rate of total flavonoids from Pueraria lobata with the most crystallization amount significantly decreased by 96.51% compared to the sample without crystallization.After further simulating the preparation process of total flavonoids from Pueraria lobata, it was found that the wet granulation process with introduced water would also lead to crystallization and reduced dissolution rate.As for all crystallization samples, there was an inversely proportional relationship between the dissolution rates and the amount of crystallization.The risk of crystallization existed both in the storage and preparation process of TCM extracts.Crystallization would significantly affect the dissolution rate, and thus the quality of TCM products.In this study, the crystallization transformation of amorphous complex TCM extracts was discovered, and the effect of the crystallization transformation on its dissolution behavior was systematically studied, which provides a new research idea for assuring the quality of TCM products and promoting the improvement of TCM preparation level.

Background:Although sustainable control since 1950s has achieved great successes,schistosomiasis japonica remains a major public health problem in China.Since 2004,a new integrated strategy was developed aiming to control the transmission of Schistosoma japonicum through the implementation of a package of interventions.To date,no systematic review or meta-analysis assessing the effectiveness of this new integrated strategy for schistosomiasis control in China has been published.We performed a PubMed-based bibliometric assessment of publications on the new integrated strategy for schistosomiasis japonica control in China,to understand the global transmissibility and sharing of the new integrated strategy.Methods:An in-depth bibliometric analysis of all publications on the new integrated strategy for schistosomiasis japonica control in China was performed through a PubMed search using the terms "schistosomiasis" and "China,"from January 1,2004 to August 31,2018.All titles and abstracts were read carefully,and the publications reporting the effectiveness,experiences,lessons,or problems of the new integrated strategy were included in the bibliometric analysis.Results:Overall,2,361 titles were screened,and 70 eligible publications were accessed for analyses,including 23 studies in English,published in 15 international journals,and 47 studies in Chinese with abstracts in English,published in 3 national journals.Chinese Journal of Schistosomiasis Control (Zhongguo Xue Xi Chong Bing Fang Zhi Za Zhi) published 60％ of the research output,Research articles (48.6％) and short reports (37.1％) were the dominant manuscript types.Furthermore,471 contributing authors from 277 affiliations across 9 countries produced these 70 publications.Conclusion:This is the first PubMed-based quantitative analysis of the research output of the new integrated strategy,and our data indicate a low global transmissibility of Chinese new integrated strategy.We therefore call for more research outputs of the new integrated strategy for schistosomiasis japonica control in China to be communicated through international platforms.

OBJECTIVETo explore the clinical efficacy differences of scalp acupuncture on brain injury in premature infants with different months of age.

METHODSAccording to the corrected months of age, 90 cases of premature infants with brain injury were divided into a group A (3 through 6 corrected months of age), a group B (7 through 9 corrected months of age) and group C (10 through 12 corrected months of age), 30 patients in each one. Based on the conventional early intervention, the infants in the group A were treated with scalp acupuncture at , motor area; the infants in the group B were treated with scalp acupuncture at , motor area and foot motor sensory area; the infants in the group C were treated with scalp acupuncture at , motor area, foot motor sensory area and balance area. All the treatment was given once every other day, and totally 30 treatments were given. The Alberta infant motor scale (AIMS), development quotient (DQ) of each function indexes in Gesell developmental scale (GDS) were observed before and after treatment; the clinical efficacy of each group was compared and the correlation between clinical efficacy and months of age was analyzed.

RESULTSCompared before treatment, the total score of AIMS and DQ of each function indexes of GDS were all improved in the three groups after treatment (all <0.01). After treatment, the differences of total score of AIMS and DQ of each function indexes of GDS among the three groups were significant (<0.05, <0.01), and the results in the group A were higher than those in the group B and the group C (<0.05, <0.01). The total effective rate was 96.3% (26/27) in the group A, which was higher than 89.7% (26/29) in the group B and 83.3% (25/30) in the group C. The correlation analysis indicated less months of age was significantly corelated with better efficacy (<0.05).

CONCLUSIONScalp acupuncture has superior improvement on the recovery of brain damage in premature infants, especially for those with 6 months of age or less.

Objective To investigate the diagnosis of the diseases that presented with childhood chronic cerebellar ataxia.Method The clinical data of 15 children with chronic cerebellar ataxia were studied,including the clinical features,laboratory results and neuroimaging aspect.Results Of the 15 children with chronic cerebellar ataxia,3 cases had chronic progressive cerebellar ataxia diagnosed as ataxia telangiectasia,and neuroimaging finding that indicated mild to marked cerebellar atrophy.The others 12 cases had non-progressive cerebellar ataxia,2 cases of them had Joubert syndrome,characterized by delayed motor function and speech,lower limbs ataxia and cerebellar vermis hypoplasia; 10 cases had ataxic cerebral palsy with delayed motor skills,9 of them had mental retardation and verbal problem.Of the 10 children with ataxic cerebral palsy,7 cases had cerebellar hemispheric atrophy by computer tomography (CT) or MRI,while the other 3 cases had no positive finding in cerebellum by MRI,but 2 of whom were found reduced metabolism in cerebellar neuron during the test of positron emission tomography and CT.Comparson with the scores in the gross motor function measure (GMFM) and developmental quotient (DQ) of 5 domains (adaption,gross motor,fine motor,language and social development) in Gesell developmental Schedules before and after the rehabilitation approach:the totaI scores in GMFM after the treatment (56.42 ± 15.65) was significantly higher than that of before traatment (44.15 ±20.41) (t =-3.121,P ＜0.05),while the DQ of gross motor after the treatment (28.27 ± 14.65) was sigrificantly lower than that before treatment (35.23 ± 17.23) (t =2.75,P ＜ 0.05).The other 4 domains before the treatment were 37.47 ± 14.47,37.06 ± 11.51,40.69 ± 12.10 and 40.41 ± 15.79,and had no remarkable change after the treatment (39.44 ±16.29,35.96 ±10.76,40.26 ±14.20 and 38.61± 11.95) (allP＞0.05).Conclusions Children with chronic cerebellar ataxia presented as hypotonia with delayed motor function,and ususlly had inherent cerobellum abnormalities,without matter structure or function of the neuron.Chronic ataxia is an important symptom in genetic or metabolic disease,and a systematic approach may enhance diagnostic accuracy.
