All previous literatures about Chinese herbal medicines show distinctive traditional Chinese medicine (TCM) flavors. Compendium of Materia Medica is an influential book in TCM history. The TCM flavor theory and flavor standardization principle in this book has important significance for modern TCM flavor standardization. Compendium of Materia Medica pays attention to the flavor theory, explain the relations between the flavor of medicine and its therapeutic effects by means of Neo-Confucianism of the Song and Ming Dynasties. However,the book has not reflected and further developed the systemic theory, which originated in the Jin and Yuan dynasty. In Compendium of Materia Medica , flavor are standardized just by tasting medicines, instead of deducing flavors. Therefore, medicine tasting should be adopted as the major method to standardize the flavor of medicine.

220.6 ?mol/L in serums.Conclusions TORCH infection is common in infantile hepatitis in hospital.The infection rates caused by CMV are higher than those caused by HSV,TOX,RV and the rate caused by TOX is lower than others,and then the injury of liver caused by CMV is more severe than others.Neonates less than 7 days always have more organs injuried than the elders.

OBJECTIVETo study the protective effect of Ligustrazine Injection (LI) against cisplatin-induced ototoxicity and to explore its mechanism.

METHODSThirty healthy adult guinea pigs were randomly divided into three groups, 10 in each group, i.e., the normal control group, the cisplatin group, and the LI group. Guinea pigs in the normal control group were intraperitoneally injected with normal saline at 3 mL/kg for 7 consecutive days. Those in the cisplatin group were intraperitoneally injected with cisplatin at 3 mg/kg for 7 consecutive days. Those in the LI group were intraperitoneally injected with LI at 140 mg/kg for 7 days, but cisplatin (3 mg/kg) was intraperitoneally injected from the opposite side starting from the 4th day. Brainstem auditory evoked potential (BAEP) was performed in all animals before and after injection. All animals were sacrificed after the final testing under anesthesia and their cochleas collected. Half the cochleas of each group were collected for silver nitrate staining of cochlear basilar membrane stretched. The other half the cochleas of each group made into paraffin sections to observe the apoptosis of cochlea cells by TUNEL method and the expression levels of c-Jun detected by immunohistochemistry.

RESULTSThere was no statistical difference in the difference of BAEP threshold among the 3 groups before injection (P > 0.05), but the BAEP threshold increased in the cisplatin group and the LI group (P < 0.05). Besides, it was higher in the cisplatin group (P < 0.05). In the cisplatin group, most hair cells were missing, spiral ganglion cells obviously decreased, more TUNEL positive cells occurred, and the expression of c-Jun was stronger. But the aforesaid impairment in the LI group was obviously lessened (P < 0.05).

CONCLUSIONSLI showed certain antagonist effect on cisplatin-induced ototoxicity. Its mechanism might be associated with scavenging oxygen radicals of the cochlea tissue, improving the microcirculation, and fighting against apoptosis.

Objective To evaluate the effect of transcatheter arterial chemoembolization (TACE) and delayed surgery for infant hepatoblastoma.Methods TACE was performed with the initial digital subtractive angiography (DSA) under general anesthesia 1-3 times in 8 infants with huge hepatoblastoma, whose age was 2 to 12 months. DSA was done via arterials in hepatoblastoma each time before chemoembolization. The arterials were perfused with chemodrugs and suspensions in ultrasome iodized oil , and were blocked with spring rings. DSA findings indicated that the tumor shrank without new tumorous arterials after 1 month in 6 cases, and 4 of them showed no tumorous staining, and the delayed surgery was performed successfully 1 week later in 6 infants. One boy underwent systemic chemotherapy alone during 6 months after 3 times of TACE. Results TACE therapy did not encounter any major technical problem or toxic reaction caused by chemotherapy. The following DSA test 4 weeks later did not detect any new tumorous vessels in 6 cases. Six children received TACE and surgery had been followed-up with no tumor recurrence for months averagely. The boy underwent TACE and venous chemotherapy for 6 months , without surgery , had been followed-up for 48 months until the present report. CT, AFP and DSA did not show any hints of tumor recurrence. Six cases receiving 3 times TACE combined with surgery survived without tumor recurrence. Conclusions TACE is a very effective, safe and helpful therapy for hepatoblastoma, which stressed the repeated use of spring ring to block tumor vessels lastingly if necessary. If surgery is required, DSA test is needed beforehand to detect new tumorous vessels or neoplasm. If there is any , TACE is repeated. TACE combined with surgery may provide an additional promising choice in the treatment of hepatoblastoma, and repeated TACE alone may cure hepatoblastoma in infants.

In this paper, the RP-HPLC specific chromatography was adopted, with DIKMA-C18 (4.6 mm x 250 mm, 5 µm) as the chromatographic column, with a gradient elution compose of acetonitrile and 0.1% phosphoric acid at flow rate of 0.8 mL · min(-1), the detection wavelength was 220 nm. The difference of the HPLC specific chromatograms between the Lu Dangshen and other different base sources and different producing area of Codonopsis Radix was compared, involved in the similarities and differences of the number and the relative peak area of characteristic peaks in the HPLC specific chromatograms. The HPLC specific chromatograms of Lu Dangshen was established and the relative retention times of seven peaks was determined, and the peaks of codonopyrrolidium B, syringin, lobetyolin, tangshenoside I and atractylenoide III were identified; The HPLC specific chromatograms of Lu Dangshen provided a method for scientific evaluation and effective control the quality of Lu Dangshen from Shanxi famous-region.

OBJECTIVETo observe the effect of calcitonin gene-related peptide (CGRP) on pulmonary vascular collagen accumulation in hypoxia rats in order to study the effect of CGRP on hypoxic pulmonary vascular structural remodeling and its possible mechanism.

METHODSRats were acclimated for 1 week, and then were randomly divided into three groups: normoxia group, hypoxia group, and hypoxia plus capsaicin group. Pulmonary arterial hypertension was induced by hypoxia in rats. Hypoxia plus capsaicin group, rats were given capsaicin (50 mg/(kg x d), s.c) 4 days before hypoxia to deplete endogenous CGRP. Hypoxia (3% O2) stimulated proliferation of pulmonary arterial smooth muscle cells (PASMCs) and proliferation was measured by BrdU marking. The expression levels of CGRP, phosphorylated ERK1/2 (p-ERK1/ 2), collagen I and collagen III were detected by real-time PCR or Western blot.

RESULTSRight ventricle systolic pressure (RVSP) and mean pulmonary arterial pressure (mPAP) of pulmonary arterial hypertension (PAH) rats induced by hypoxia were higher than those of normoxia rats. By HE and Masson staining, it was demonstrated that hypoxia also significantly induced hypertrophy of pulmonary arteries and increased level of collagen accumulation. Hypoxia dramatically decreased the CGRP level and increased the expression of p-ERK1/2, collagen I, collagen III in pulmonary arteries. All these effects of hypoxia were further aggravated by pre-treatment of rats with capsaicin. CGRP concentration-dependently inhibited hypoxia-induced proliferation of PASMCs, markedly decreased the expression of p-ERK1/2, collagen I and collagen III. All these effects of CGRP were abolished in the presence of CGRP8-37.

CONCLUSIONThese results suggest that CGRP might inhibit hypoxia-induced PAH and pulmonary vascular remodeling, through inhibiting phosphorylation of ERK1/2 and alleviating the collagen accumulation of pulmonary arteries.
