OBJECTIVETo study the effect and mechanism of Ganbi decoction (GBD) in treating patients with antituberculotic agent caused liver injury (ATB-LI).

METHODSOne hundred and twenty-eight patients with ATB-LI were randomly assigned to the treated group (n = 66) and the control group (n = 62) with the envelop method. Meanwhile, 60 healthy persons were selected as the healthy control group. The treated group was treated by GBD one dose every day with the constituents modified depending on patients' symptoms, and the control group was treated with glucuronolactone tablets and inosine injection. One week was taken as one treatment course. The changes of clinical syndromes, physical signs, T-lymphycyte sub-groups and serum level of nitric oxide (NO) were observed before and after treatment and the recovery time of liver function was recorded. The outcome was compared with that in the healthy control group.

RESULTSIn the treated group, 28 patients (42.4%) were cured, 30 (45.5%) improved and 8 (12.1%) ineffectively cured, the total effective rate being 87.9% (58/66). In the control group, 17 patients (27.4%) were cured, 24 (38.7%) improved, and 21 (33.9%) ineffectively cured, the total effective rate being 66.1% (41/62). The total effective rate in the treated group was significantly higher than that in the control group (P < 0.05). Liver function was improved in both groups, recovery time in the treated group was 12.0 +/- 7.0 days, which was significantly shorter than that in the control group (16.0 +/- 8.0 days), showing significant difference between the two groups (P < 0.05). The levels of CD3, CD4 and CD8 were significantly higher and level of NO significantly lower in the two groups of patients than those in the healthy control group (P < 0.05), but these parameters were improved more significantly in the treated group after treatment, when compared with those before treatment or with those in the control group, all showing significant difference (P < 0.05).

CONCLUSIONGBD could prevent ATB-LI, and its mechanism could be by way of reducing NO production induced by endotoxin of macrophage and stimulating the proliferation of T-lymphycyte to elevate immunity.

OBJECTIVETo evaluate the effects of Caulis Sinomenii and sinomenine on conditioned place preference (CPP) induced by morphine and brain histamine level in mice.

METHODSSixty mice were randomized into 6 equal groups and morphine (Mor) was injected subcutaneously (9 mg/kg) for 6 consecutive days to induce CPP using a shuttle box. Since the 4th day of training, the mice in 5 of the groups were treated for 3 consecutive days with Caulis Sinomenii (10 g/kg), sinomenine (60 mg/kg), diphenhydramine (30 mg/kg), CP48/80 (5 mg/kg) and L-histidine (750 mg/kg) in addition to morphine (9 mg/kg) treatment, respectively, leaving the other group with exclusive morphine treatment. Another 10 mice received saline injection to serve as saline control group. The content of histamine (HA) in the mouse brain was measured by fluorospectrophotometry.

RESULTSIn morphine group, the mice showed significantly extended stay in morphine-paired compartment whose HA content in the brain was markedly increased (P<0.01). Treatment with Caulis Sinomenii and sinomenine resulted in significantly reduced time of stay in morphine-paired compartment and brain HA level (P<0.01).

CONCLUSIONCPP induced by morphine in mice is associated with increased HA level in the brain. Caulis Sinomenii and sinomenine can suppress the acquisition of place preference induced by morphine and modulate HA level in the central nervous system in morphine-dependent mice.

OBJECTIVETo evaluate the effects of Wenchuan Earthquake on the nutritional status, growth, and the prevalence nutritional anemia, vitamin A deficiency (VAD) and vitamin D deficiency among children under 60 months old living in the disaster areas.

METHODSA nutritional survey was conducted in April 2009. The survey recruited 466 under 60 months old children, including 162 children aged 0 months old and 304 children aged 24 - 59 months old. The children's growth status, prevalence of anemia, and the iron deficiency prevalence, vitamin A, D, B(12), folic acid status were measured. The study findings were compared to the results from 2002 Chinese Nutritional and Health Survey.

RESULTSThe exclusive breast milk feeding rate among infants under 6-months was 58.8% (30/51). Among the 0 - 23 months old children, only 10.7% (16/150) got breast feeding within one hour after delivery. Ninety-two per cent (149/162) 0 - 23 months old children never received any nutrient supplements. The average cereals and roots intakes of the 24 - 59 months old children living in the disaster area were (267.2 ± 154.3) g/d, higher than the result of rural children average (178.75 g/d) of 2002 National Nutrition and Health Survey (u = 9.995, P < 0.01). The average intakes of vegetables, aquatic products, meat and poultries were (63.6 ± 56.7), (2.6 ± 7.9), (19.4 ± 24.0) g/d, respectively, significantly lower than 2002 results 135.05, 8.82 and 32.23 g/d (u = 21.971, 13.728 and 9.321, P < 0.01). Fruits, dairy products and legumes intakes were (102.2 ± 110.8), (65.2 ± 123.8) and (20.5 ± 29.0) g/d, respectively, higher than 2002 results (32.81, 2.87 and 6.50 g/d; u = 10.919, 8.778 and 8.417, P < 0.01). The prevalence of vitamin A deficiency and marginal deficiency was 15.4% (29/188) and 30.3% (57/188), respectively. The sum of vitamin D deficiency and insufficiency was 92.0% (183/199). The prevalence of anemia of the 0-months old children and 24 - 59 months old children was 47.5% (77/162) and 21.5% (60/279), respectively. The prevalence of iron and zinc deficiencies was 45.7% (86/188) and 65.5% (127/197). The prevalence of stunt was 13.6% (38/279) among the 24 - 59 months old children.

CONCLUSIONThe results indicated that the dietary structure of the children living in the disaster area was not ideal. Although, the intakes of energy and protein supporting foods could meet the requirements, but the dietary lacks of meats, poultries, dairy products, legume products, aquatic products and vegetables. The vitamin A, vitamin D deficiency, iron and zinc deficiencies are of a high prevalence in the disaster area.

OBJECTIVETo evaluate the effects of Wenchuan Earthquake on the nutritional status and the prevalence of nutritional anemia, vitamin A deficiency (VAD) and vitamin D deficiency among reproductive women (15 - 44 years old) in the disaster areas one year after the Earthquake.

METHODSA nutritional survey was conducted in 3 counties in April 2009, one year after the Earthquake. Two towns from each county were selected as study sites, and this survey recruited 58 pregnant, 66 lactating and 242 non-pregnant-non-lactating women. A comparison was made to the results of 2002 Chinese Nutrition and Health Survey.

RESULTSThe cereals and roots intakes of the pregnant, lactating and non-pregnant-non-lactating women living in the disaster area were (426.8 ± 271.8), (568.0 ± 306.1), and (483.0 ± 277.7) g/d respectively, which were almost the same results (486.8, 509.3 and 495.1 g/d, respectively) from 2002 National Nutrition and Health Survey. The fat and oil intakes were (41.9 ± 51.6), (55.5 ± 69.2), and (66.9 ± 125.7) g/d, respectively, which were also the same ad the results (45.2, 43.9 and 41.4 g/d, respectively) from 2002 National Nutrition and Health Survey. The intakes of meats and poultries were only (58.1 ± 67.7), (76.3 ± 218.7), and (23.9 ± 29.6) g/d respectively, which were much lower than the recommended food intakes from the Branch of Maternal and Child Nutrition of Chinese Nutrition Society. The vitamin A deficiency and marginal deficiency prevalence were 6.9% (24/347) and 18.2% (63/347), respectively. The deficiency and insufficiency of vitamin D was sum to 93.9% (323/344). The prevalence of anemia was 32.6% (112/344). 51.0% (171/335) reproductive women were iron deficient, and 61.6% (210/347) women were suffering zinc deficiency.

CONCLUSIONThe study findings indicated that the dietary structure was seriously effected by the Earthquake. The sources from animal and legume products were relatively low. The micronutrients nutritional status was poor. The vitamin A, vitamin D, and iron, zinc deficiencies were highly prevalent in the disaster area.

OBJECTIVETo establish and evaluate a protein microarray method for combined measurement of serum ferritin (SF) and soluble transferrin receptor (sTfR).

METHODSMicroarrayer was used to print both anti-SF antibodies I and anti-sTfR antibodies I on each protein microarray. Anti-SF antibodies II and anti-sTfR antibodies II were used as detection antibodies and goat antibodies coupled to Cy3 were used as antibodies III. The detection conditions of the quantitative analysis method for simultaneous measurement of SF and sTfR with protein microarray were optimized and evaluated. The protein microarray was compared with commercially available traditional tests with 26 serum samples.

RESULTSBy comparison experiment, mouse monoclonal antibodies were chosen as the probes and contact printing was chosen as the printing method. The concentrations of SF and sTfR probes were 0.5 mg/mL and 0.5 mg/mL respectively, while those of SF and sTfR detection antibodies were 5 μg/mL and 0.36 μg/mL respectively. Intra- and inter-assay variability was between 3.26% and 18.38% for all tests. The regression coefficients comparing protein microarray with traditional test assays were better than 0.81 for SF and sTfR.

CONCLUSIONThe present study has established a protein microarray method for combined measurement of SF and sTfR.

OBJECTIVETo explore the effects of growth hormone( GH) supplementation on erectile function and expression of nNOS in the intracavernosal nerves in aging rats.

METHODSTwenty male Sprague-Dawley rats aged 18 months were randomly divided into Groups A and B, and ten 2-month-old male Sprague-Dawley rats included in Group C. 1 U/(kg x d) GH was given to Group A, and the same volume of saline to Groups B and C. After 8 weeks of treatment, evaluation was made of the erections induced by apomorphine (APO), maximal intracavernous pressure (ICP) induced by intracavernous papaverine injection and expression of nNOS in the intracavernosal nerves by streptavidin-peroxidase immunohistochemical techniques.

RESULTSAfter 8 weeks of treatment, the erection frequency, maximal ICP and expression of nNOS in the intracavernosal nerves of the rats in Groups A and C were significantly higher than those in Group B (P < 0.05 or P < 0.01).

CONCLUSIONGrowth hormone supplementation can improve the erectile function of aging rats, which may be attributed to the increase in the expression of nNOS in the intracavernosal nerves.
