BACKGROUND:. Until now modern science cannot explain clearly aboutthe mechanism of acute alcoholic liver injury. Besides such methods as givingup drinking, or symptomatic treatment, there is no specific therapy and remedy. Traditional Chinese Medicine (TCM) has obvious advantages for this: Itcannot only improve the clinical symptoms, but also adjust organism immunefunction, and has very good development future. OBJECTIVE: To study the effects of radix bupleuri and radix scutellariae incompatibility with the ratio of different dosage (2:1, 1:1, 1:2) on acute alcoholicliver injury by regulating the system of endocrine-immunity network in rats. DESIGN: Groups are divided randomly and experiments are made underblank conditions. SETTING: TCM Clinical Laboratory of Pharmaceutical School, Henan University of TCM. MATERIALS: From September to November 2002 in TCM Clinical Laboratory of Pharmaceutical School, Henan University of TCM, the general condi tion of the animals were as follows: 96 healthy Wistar rats were divided into 8groups: blank group, model group, radix bupleuri group, radix scutellariaegroup, xiao-chaihu group, radix bupleuri-radix scutellariae 2:1 group, radix bupleuri-radix scutellariae 1:1 group, radix bupleuri-radix scutellariae 1:2 group. METHODS: ① According to the ratio of 2:1, 1:1, 1:2, radix bupleuri andradix scutellariae were taken respectively (480 g, 240 g; 360 g, 360 g; 240 g, 480 g) to produce the water decocting nedicine. Except the blank group(duplicated by saline of the same volume through consecutive gastric infusion), the other groups are duplicated through consecutive gastric infusionby 56 degrees of Er-Guotou White Spirit (7 mL/kg) two times a day for tendays until the model-making is finished. From the first day, the medicine wasgiven two times a day. The blank group and the model group were given thedistilled water of the same volume. The other groups were given the properwater decocting medicine. The dosage in xiao-chaihu group was 10 g/kg andin the other was all 12 g/kg. ② 16 hours later after the last time when thewhite spirit was given, blood was taken from stomach aorta to produceserum. Liver, spleen, chest gland, adrenal gland were quickly removed. Thecalculating formula of an organ index: An organ index= The weight of an organ (g)/The weight of a body (g) ×100%. The calculating formula of vitamin C content in adrenal gland (mg/g): Content of vitamin C= [(The Avalue of the testing tube-The A value of the blank tube)/ (The A value ofthe standard tube-The A value of the blank tube)] ×density of the standardtube (6 mg/L)×dilution times of the sample before tested/protein content(g/L). ③ Comparison between the groups was shown by using variancesimilar test and single-factor variance analysis.MAIN OUTCOME MEASURES: Index of rats' liver, spleen, chest gland, and adrenal gland (on the right side); the determination of vitamin C content in rats' right adrenal gland.RESULTS: During the experiment, 3 rats in the model group died. Tworats died in radix scutellariae group and radix bupleuri-radix scutellariae group respectively, In each of the other groups only one rat died. The condition of the number of the rats which were used for analyzing results:There were 12 in blank group; 9 in model group; 10 in radix bupleuri group, radix bupleuri-radix scutellariae 1:1 group respectively; 11 in each of the other groups. ① Comparison of index of rats in liver, spleen, chest gland, adrenal gland (right side) between different groups: There was no significant difference between the indexes of rats' liver in different groups.The index of spleen, chest gland, adrenal gland in the model group were all greatly less than in blank group (P ＜ 0.05-0.01). The index of spleen in the radix bupleuri group wcre greatly higher than in the model group, it could make the reduced spleen index return to normal (P ＜ 0.05); The index of chest in radix scutellariae group, radix bupleuri-radix scutellariae 1:1 group, radix bupleuri-radix scutellariae 1:2 group and xiao-chaihu group were greatly higher than in model group (P ＜ 0.05); The index of adrenal gland in radix bupleuri-radix scutellariae 1:2 group and xiao-chaihu group were greatly higher than in model group (P ＜ 0.05). ② Comparison of vitamin C content in rats' right adrenal gland between the groups: Compared with blank group, the vitamin C content of adrenal gland in the model group had no significant difference. While that of radix bupleuri group, xiao-chaihu group, radix bupleuri-radix scutellariae groups were greatly less than that of model group (P ＜ 0.05-0.01), especially radix bupleuri-radix scutellariae 1:1 group had the most significant influence (P ＜ 0.01).CONCLUSION: Interfering functional injuries of liver, spleen and suprarenal gland is one of the mechanisms of acute alcoholic liver injury.Generally speaking, bupleuri-radix scutellariae 1:2 group has the greatest effect on the testing index.

Objective To report clinical characteristics and genetic results of two sisters suffered from congenital adrenal cortex hyperplasia (17-α-hydroxylase deficiency), and relevant literatures were reviewed. Methods Clinical manifestation and laboratory examination data of two sister cases of 17-α-hydroxylase deficiency enrolled in Capital Institute of Pediatrics in March 2016 were analyzed. Sanger sequencing and MLPA for CYP17A1 genes were performed and the parents' genes were also verified. Results The two patients were four years and 10 years old, both suffered from hypokalemia after infections, and hypergonadotrophin gonad hypofunction. One case was with slightly high blood pressure. Laboratory test results showed potassium fluctuation tendency in 1.9~4.0 mmol/L, 17-OHP and DHEA was decreased. Enhanced CT showed different degree of adrenal gland enlargement. Chromosome examination of the older sister is 46, XY. Both sisters demonstrated heterozygous mutation of CYP17A1 gene. The molecular genetic analysis suggested a c.985_987delTACinsAA from father and a deletion spanning exons 1-7 of the CYP17A1 gene from mother. Conclusion 17-α-hydroxylase enzyme deficiency can be diagnosed before adolescence. Clinical hypokalemia with unknown reason and high blood pressure may indicate the disease. The diagnosis can be confirmed with gene sequencing of CYP17A1.

OBJECTIVETo investigate the synergistic effect of transforming growth factor-beta1 (TGF-beta1) and platelet-derived growth factor-BB (PDGF-BB) on the expression of integrin beta3, in periodontal membrane of rat orthodontic tooth.

METHODSAn orthodontic tooth movement model was established. Up to 32 experimental rats were randomly divided into four groups according to a random number table. The four groups were injected with 1% PBS, TGF-beta1 (5 ng), PDGF-BB (10 ng), and combined TGF-beta1 (5 ng) and PDGF-BB (10 ng) in the buccal submucosal, respectively. The volume injected in each group was 0.1 mL. The animals were then sacrificed on the 10th day. The left maxillary first molar and periodontal tissue were taken. Different expressions of integrin beta3 were detected in periodontal tissues through immunohistochemistry. Mean optical density (OD) values of the positive fields were examined. The data obtained were analyzed through ANOVA. The data followed normal distribution, and were compared via t-test.

RESULTSCompared with the control groups, the expression of integrin beta3 was higher in the experimental groupin tension sides (P < 0.01). Significant differences in tension sides between the single-injection groups and the combined group were observed (P < 0.01). Compared with the control groups, the expression of integrin beta3 was higher in the experimental group in compression sides (P < 0.05). In addition, there was no significant differences in compression sides between the single-injection groups and the combined group (P > 0.05).

CONCLUSIONIn terms of local regulatory factors, TGF-beta1 combined with PDGF-BB enhance the expression of integrin beta3 in the periodontal membrane and accelerate periodontal remodeling. The synergistic effect of the two growth factors is better than the single growth factor.
