In order to study the etiology , pathogenesis , and therapy of neonatal hyperbilirubinemia through animal models , we review the literature on rodent and primate models of neonatal hyperbilirubinemia ,including establishment of models and their applications , in order to provide reference for the research of neonatal hyperbilirubinemia .

Objective To investigate the presentation and radiologic findings of acute marchiafava‐bignami disease(MBD) . Methods Three cases of acute MBD who were diagnosed and treated in our hospital were retrospectively analyzed ,including the clinical symptoms ,laboratory tests ,imaging examination(such as cranial CT ,magnetic resonance imaging(MRI) ,prognosis .Results Three cases were acute onset .The symptoms may be non‐specific ,such as consciousness disorder ,psychosis ,seizures ,delirium tremor and high fever .The imaging changes in the genu and splenium of corpus callosum could be found ,even in the bihemispheric white matter of all cases .CT revealed low‐density areas ,meanwhile MRI showed iso‐or hypo‐intensity on T1WI and ADC ,hyper‐in‐tensity on T2WI and fluid attenuated inversion recovery and restricted diffusion weighted imaging .The lesions involved in bihemi‐spheric brachium pontis in one case and in the body of corpus callosum in another case .Conclusion Acute MBD may present with various clinical forms ,but have characteristic imaging findings .

In the 1960s, modern science began involving the essence of heat syndrome, but there have still no in-depth systematic studies on pathological mechanisms of heat syndrome and action mechanisms of cold and cool herbs. In this study, the animal model with heat syndrome was set up by feeding herbs with hot property, and then cold and cool herbs was applied in the experimental therapy. The two-dimensional electrophoresis and mass spectrometry technologies were adopted to compare the liver mitochondria proteome of the rats of the heat syndrome model and the ones treated with cold and cool herbs, so as to discover specificity-related proteins after heat syndrome and treatment with cold and cool herbs.

HPLC fingerprint of Congrong Zonggan capsule was established in order to provide basis for quality evaluation. With acteoside as the reference, HPLC was adopted for fingerprint analysis on Congrong Zonggan capsule. The chromatographic conditions wereas follows. Waters C18 column (4.6 mm x 150 mm, 5 μm) was used, with methylalcohol-0.1% formic acid as the mobile phase for gradient elution at the flow rate of 1.0 mL x min(-1). The detection wavelength was 330 nm, and the column temperature was 30 °C. This method was highly accurate and reproducible. All of the 13 components in tested samples reached the baseline resolved peak, and 15 batches of finished products showed the similarity of above 0.95. The method was accurate and feasible and could be used as a simple and effective method to evaluate the quality of the traditional Chinese medicines.

Objective To investigate the influence of primary cultured neonatal rat hippocampal neurons caused by human cytomegalovirus (HCMV AD169) infection on intracellular calcium and its mechanism.Methods Twenty SPF SD rats born within 24 hours(10 cases of male and 10 cases of female) were assigned to establish the primary rat hippocampal neuronal monolayer cells; After cultured 8 days in vitro,the eligible cells were randomly divided into HCMV infection group,HCMV + MK-801 group,MK-801 group and control group,with 10 wells in each group.The fluorescence intensity values of the intracellular free calcium were detected after 24 hours of treatment with Fluo-3AM fluorescence staining.Results Inoculation of HCMV neurons after 24 h turned to round and swollen gradually,and 4days later,most of the cells disappeared; by immunohistochemistry in cultures of hippocampal neurons in HCMV,visible early proteins,brownish yellow granules,hematoxylin were found after being stained with brown pigment.The fluorescence intensity values of neuronal intracellular calcium (215.5 ± 14.9) in HCMV group was higher than that of control group (116.4 ± 5.9) (t =15.2,P ＜ 0.01),whilerise,that in MK-801 group (88.1 ± 4.5) was significantly lower than that of control group,with decreased rate of (24.0 ± 6.7) ％ (t =-9.3,P ＜ 0.01).The fluorescence intensity values of neuronal intracellular calcium in HCMV + MK-801 group (135.5 ± 8.6) was significantly decreased compared with that of HCMV group (215.5 ± 14.9),with decreased rate of (37.0 ± 3.4) ％ (t =11.3,P ＜ 0.01).Conclusions Intracellular calcium overload of cultured rat hippocampal neurons in vitro with HCMV AD16 strains infection can be detected.One of its main mechanisms is the N-methyl-D-aspartic acid receptor channel-mediated calcium influx.

Objective To observe the curative effect of low melocular weight heparin(LMWH) on the hypercoagulability in acute Kawasaki disease(KD).Methods Forty-six patients were diagnosed KD.Twenty-two cases out of all KD patients whose serum concentration of whether platelet(PLT) or fibrinogen(FIB) was significantly increased or who were found thrombus in their coronary artery by ultrasonic Doppler were treated with LMWH by subcutaneous injection once every day for 7-10 days.All the patients were divided into 2 groups accor-ding to whether using LMWH or not:H group(using LMWH) and NH group(no using LMWH).It were detected before and after treatment that included thrombin time(TT),activated partial thromboplastin time(APTT),international normalized ratio(INR),FIB,plasma mucosity,erythrocyte sedimentation rate(ESR),hematocrit(HCT) and situation of haemorrhage.Results 1.Before treatment,PLT and FIB of patients in H group were significantly higher than those in NH group(Pa
