Journal of Traditional Chinese Medicine 1993;0(01):-
Objective To observe the therapeutic effect of Sanzi Yangqing Decoction (Decoction of three kinds of seeds) for mammary cystic hyperplasia.Methods Totally 113 patients with mammary cystic hyperplastia were randomized into a treatment group (58 cases) which was prescribed Sanzi Yangqing Decoction and a control group (55 cases) which was given Ruhe Sanjie Tablet (Tablet for dissolving mammary masses). Both were treated for 3 courses. Before and after treatment the clinical symptoms and signs, hormones in serum of both groups, and the indices of hemodynamics of the treatment group were observed.Results The total effective rate of the treatment group was 89.66%, while that of the control group was 65.45%, there was significant difference (P

Objective To explore the differences between the minority nationality and Han recruits in army occupational adaptability.Methods 3 213 recruited youths coming from 29 autonomous counties of minority nationalities,Yunnan Province were tested by 2011 Chinese enrollment psychological test system to explore the differences of the intelligence adaptability and character trait adaptability between the minority nationality and Han recruits.Results There were obvious differences in the eligible rates of intelligence and character trait between minority nationality and Han recruits ( x2 =13.3,9.0; P < 0.01 ).The intelligence eligible rates of Yi,Hani,Wa recruits (78.1%,76.8%,68.2%,respectively) were significantly lower than those of Han recruits (84.0%) (P<0.01 ),and time used in three intelligence test was all significantly longer than Han recruits(P < 0.05 ).Naxi and Dai recruits' time used in word reasoning ( ( 109.2 ± 20.9) s; ( 123.9 ± 32.5 ) s,respectively) was both longer than Han recruits' (P<0.01).In the fact of character trait,the eligible rates of Hani,Wa recruits (67.8%,64.3%,respectively) were significantly lower than that of Han recruits (78.1%) (P < 0.01 ).The Hani average score of T dimension (57.9 ± 17.5) was obviously higher than the Han's score (52.2 ± 16.5) (P < 0.05 ).All dimensions average scores except T and D dimension of Wa recruits were all significantly higher than those in Han recruits(P < 0.05 ).Conclusion Every minority nationality has its unique differences in armyoccupational adaptability from Han.Ethnic factor may be an important reference for new recruits' selection,education and management.

Objective To explore the time course of response inhibition function in juvenile delin-quents with antisocial personality characteristics.Methods The healthy control group ( n=21),juvenile delinquents with antisocial personality characteristics ( CD +AP ) ( n=18) and juvenile delinquents ( CD) ( n=18) were selected in current study by recording the event-related potentials in a Go/Nogo task.N2 and P3 components of event-related potentials were analyzed.Results Behavioral results showed that Nogo cor-rection rate of control group ((93.13±2.71)%) were significantly higher than CD group ((87.51±2.82)%, P<0.01) and CD +AP group((85.63±2.45)%, P<0.01).In CD+AP group,the amplitude of the N2nogo ( (-1.82±1.64)μV) was significantly lower than control group ( (-6.36±2.93)μV, P<0.01) ,and the am-plitude of the P3nogo ((5.52±2.79)μV) was significantly decreased than healthy control ((11.26±4.92)μV, P<0.01).In CD group,the amplitude of P3nogo ((5.20±3.17)μV) was significantly reduced than healthy control ((11.26±4.92)μV, P<0.01).Conclusion N2nogo and N2d are associated with the early phases of response inhibition and reflected response conflict.P3nogo and P3d are associated with the late phases of response inhibition and monitored inhibitory control.These data suggest that CD+AP participants exhibited im-paired response conflict and inhibitory control.This may be associated with persistent antisocial behavior.

Liver diseases are serious diseases harmful for human health. CCl4 induced liver injury, as a classic liver injury model, has been widely used in the screening of hepatoprotective drugs. This paper reviewed the research progress in the hepatoprotective effect of traditional Chinese medicines ( TCMs) on CCl4 induced acute liver injury in recent years, which can provide basis for searching TC-Ms with high efficiency and low toxicity and lay foundation for TCMs in the treatment of liver diseases.

Objective To improve the diagnosis rate and decrease misdiagnosis through analyzing the clinical and experimental features of neuroblastoma (NB) in children.Methods The clinical and experimental features associated with the misdiagnosis factors of 22 NB cases were analyzed retrospectively.Results Of the 22 cases,leg pain in 15 cases (68.18 %),fever in 19 cases (86.36 %),anemia in 20 cases (90.90 %),abdominal pain and bloating in 15 cases (68.18 %),exophthalmoses and bruises eyes in 4 cases (18.18 %) and easily perspire in 20 cases (90.90 %).Abdomen was the most common primary site founding in 16 cases (accounting for 72.72 %),followed by mediastinum founding in 4 cases (accounting for 18.18 %),other sites were 2 cases (9.09 %).Laboratory results showed that anemia was the most common cause in 20 cases (90.90 %),oligoleukocythemia in 2 cases (9.09 %) and less in thrombocytopenia about 3 cases (13.63 %).Elevated values were recorded in 77.77 % of patients for vanillylmandelic acid (VMA),86.36 % for ferritin (Fer),90.90 % for lactate dehydrogenase (LDH),and in 100.00 % for neuron specific enolase (NSE).20 cases were found metastasis when diagnosed,which accounted for 90.90 %.16 cases (72.72 %) were found tumour cells which determined in bone marrow and 20 cases (90.90 %) were positive for CD56-FITC/CD81-PE/CD45-Percp by flow cytometry (FCM).12 (54.54 %) of 22 NB cases were misdiagnosed for rheumatoid diseases (4 cases),dyspepsia (4 cases),leukemia (3 cases) and thrambocytopenia (1 case).In 22 cases,20 cases (90.90 %) were positive for CT scan.16 cases (72.72 %) were positive for abdominal B ultrasonography,and 14 cases (63.63 %) were positive for radionuclide bone scan.Conclusion Bultrasonography and CT scan will contribute to find the primary focus of NB at early stage.VMA,bone marrow smear,biopsy and FCM detection could reduce misdiagnose rate.

Objective To investigate the effect of the aqueous extracts from Dioscorea nipponica Makino (AEDN) against the carbon tetrachloride (CCl4)-induced mice acute liver injury by regulating TLR4/MyD88 signal pathway.Methods 60 mice were randomly divided into control group, model group, low, medium and high dose AEDN groups according to radom number table with 10 mice in each group. Mice in low, medium and high dose AEDN groups were adiminstrated with 50, 100 and 200 mg/kg AEDN, in control and model groups were adiminstrated with solvent once a day for 7 consecutive days. Two hours after the last administration, mice were intraperitoneal injected with with 0.3% CCl4 olive oil solution to induce acute liver injury model, except for the mice in control group. Twenty-four hours after injection, the expressions of TLR4, MyD88 and NF-κB in liver tissue were evaluated by Western blot, mRNA levels were evaluated by PCR, and the AST and ALT levels in serum were also detected.Results Compared with model group, the serum AST (98.00 ± 17.75 U/L, 57.49 ± 9.66 U/L, 39.60 ± 9.49 U/Lvs. 113.40 ± 9.71 U/L) and ALT levels (76.00 ± 14.73 U/L, 50.70 ± 9.35 U/L, 35.25 ± 9.93 U/Lvs. 95.42 ± 11.64 U/L) were significantly decreased in low, medium and high dose AEDN groups (P<0.01); MyD88 (0.67 ± 0.21vs. 1.74 ± 0.42), NF-κB p65 (0.51 ± 0.09vs. 1.76 ± 0.31) and TLR4 (0.97 ± 0.25vs. 2.99 ± 0.72) levels were down-regulated in high dose AEDN group (P<0.01); the mRNA levels of IL-6 (2.22 ± 0.25, 1.76 ± 0.31vs. 5.20 ± 0.60), IL-1β (1.96 ± 0.35, 1.47 ± 0.23vs. 7.37 ± 0.99)、TNF-α (2.06 ± 0.25, 1.34 ± 0.33vs. 2.98 ± 0.50) in medium and high dose AEDN groups significantly decresed (P<0.01).Conclusions The AEDN has protective effect against CCl4-induced acute liver injury in mice via adjusting TLR4/MyD88 signal pathway.
