Objective To discuss the clinical features of HbeAg-negative chronic hepatitis B patients associate with non-alcoholic fatty liver disease (NAFLD), to value the effect of combining treatment on fatty liver influence and antivi-ral therapy. Methods Nighty eight chronic hepatitis B patients with non-alcoholic fatty liver disease (NAFLD) (Liver pa-thology G≥2 or S≥2,HBV DNA>1 × 105 copies/mL), were observed and given antiviral therapy with interferon alpha 1 b for 24 weeks. These patients were divided into combined treatment group (55 cases treated with interferon alpha 1 b combined with Jian Gan Jiang Zhi pills) and control group (43 cases treated with interferon alpha 1 b) in accordance with random num-ber table. All these patients took Leucoson to prevent blood cells reduction. The combined treatment effect was analyzed by observing and comparing biochemical serum change and HBV DNA negative conversion ratio between two groups. Re-sults After 24 weeks of antiviral therapy in Chronic hepatitis B patients with negative HBeAg associated with NAFLD, ALT and AST decreased significantly in both treatment group and control group. And this change is more obvious in treat-ment group than in control group. TC and TG in treatment group and TC in control group were also dropped with treatment (P<0.05). There is significant difference on HBV DNA negative conversion ratio between treatment groupand control group (98.2%vs 86.0%,P<0.05). Conclusion The combination of antiviral treatment and anti fatty liver treatment can obviously improve liver function and blood lipids, increase negative conversion ratio of HBV DNA for chronic hepatitis B patients asso-ciated with NAFLD.

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 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.

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.

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.

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.
