RESUMEN
ObjectiveTo study a therapeutic reference range and laboratory alert level of amisulpride in the clinical treatment of schizophrenia. MethodsPatients who met the diagnostic criteria for schizophrenia in the International Classification of Diseases, tenth edition (ICD-10) were enrolled, and all patients received amisulpride treatment. Data including age, gender, duration of treatment, single daily dose, clinical diagnosis, amisulpride concentration, the scores of the Scale for the Assessment of Positive Symptoms (SAPS), Scale for the Assessment of Negative Symptoms (SANS) and Positive and Negative Syndrome Scale (PANSS), the adverse reaction rate and multitherapy were collected. The concentration of amisulpride was compared within different efficacy groups and different dosage groups, meantime, the incidence rate of adverse reactions was compared within different amisulpride concentration groups, and between monotherapy and multitherapy groups. Thereafter, the therapeutic reference range and laboratory alert level of amisulpride in the clinical treatment of schizophrenia were explored via estimating the negative and positive predictive values. ResultsThe amisulpride concentration yielded no statistical difference within different dosage groups and different efficacy groups (F=0.745, 1.343, P>0.05). The single daily dose among patients in different efficacy groups demonstrated no significant difference (F=0.902, P>0.05). The correlation between amisulpride treatment efficacy and its concentration denoted no statistical significance (r=0.023, P=0.744). The clinical efficacy and adverse reaction rate showed no significant difference between monotherapy group and multitherapy group (F=2.198, 0.095, P>0.05). The concentration of amisulpride was not linearly correlated with the adverse reaction rates [y=100x/(78.13+x), r=0.960]. When amisulpride concentrations ranged from 100 to 600 ng/mL, the mean reduction rate was equal to or above 42%, the effective detection rate of the reference cut-off value was equal to or above 1.485, and the incidence of adverse reactions was equal to or below 85%. When amisulpride concentrations ranged from 1400 to 1800 ng/mL, there was a decreasing trend in reduction rate (all<42%) and an increasing trend in adverse reaction rate (all>85%) as the concentration of amisulpride increased. ConclusionA reference range of 100~600 ng/mL and an alert level of 1400 ng/mL are recommended for the clinical safety of amisulpride.
RESUMEN
OBJECTIVE To discuss the correlation between effectual time and the curative effect in patients with all frequency descending sudden deafness. METHODS According to effectual time,the subjects were divided into first week effectual group and second week effectual group and the curative effect of each group was compared. RESULTS In patients with flat descent sudden deafness, the curative rate of the first week effectual group was higher than that of the second week effectual group, but there was no significant difference between the two groups(χ2=1.599, P =0.206). Meanwhile, the total significant effective rate of the first week effectual group was higher than that of the second week effectual group, without obvious difference between the two groups(χ2=0.124, P =0.725). Furthermore, in patients with total deafness type of sudden deafness, the curative rate of the first week effectual group was higher than that of the second week effectual group, showing no remarkable difference between the two groups(χ2=2.493, P =0.114). Besides, there was no remarkable difference in the comparison of the total significant effective rate (χ2=2.308, P =0.129), which was higher in the first week effectual group than that in the second week effectual group. CONCLUSION The course of treatment should be at least 2 weeks in patients with all frequency descending sudden deafness after onset.
RESUMEN
V-raf murine sarcoma viral oncogene homolog B1 (BRAF) is a pro-oncogene, which is one member of the RAF family. Mutated BRAF is found in approximately 8% of human tumors. BRAF gene mutations lead to continuous activation of the mitogen-activatd protein kinase (MAPK) pathway, which resulting in abnormal cell proliferation and tumorigenesis. In recent years, recurrent MAPK signaling mutations were identified in ameloblastoma, among which BRAF-V600E is the most prominent type. This provides new strategies for the targeted treatment of ameloblastoma. This paper reviewed the latest advances in BRAF gene mutation associated with ameloblastoma and its potential clinical significance.

BACKGROUND: The upward attack of drug-heat is a special type of syndromes of coexistence of cold and heat, it influence the treatment and conversion of the primary disease.OBJECTIVE: To investigate the pathophysiological basis of upward attack of drug-heat.DESIGN: A randomized and controlled observation. SETTING: Department of Traditional Chinese Medicine (TCM) of the People' s Central Hospital of Huizhou City.PARTICIPANTS: Totally 427 patients with cold syndrome, visiting on Department of TCM of the People's Central Hospital of Huizhou City from January 1996 to December 2001, were given warm-heat remedy. Among them 66 cases, 30 males and 36 females, got upward attack of drug-heat during the process of treatment were enrolled. All these subjects, according to their visiting order, at a ratio of 2:1, were chosen as treatment group (44 cases) and control group (22 cases).METHODS: For the patients in treatment group: Rhubarb 6 g was added boiling water 100 mL and soaked for 8 minutes, then the soaking solution was given to the patients, once a day, for 3 days successively. For patients in control group: Table salt 6 g was added boiling water 100 mL for soaking for 8 minutes, after the salt was completely dissolved, the solution was given to the patients, once a day for 3 days successively. The patients of the two groups were at the same time given remedy to treat cold syndrome. The changes of free triiodothyronine (FT3), free thyronine (FT4), high sensitizing thyroid-stimulating hormone (HS-TSH) and cortisol of the patients were detected before and after administration of warm-heat remedy, before and after medication with rhubarb. MAIN OUTCOME MEASURES: ① The changes of the relevant hormones of the patients with upward attack of drug-heat before and after ad ministration of warm-heat remedy. ② The changes of the relevant hormones of the patients with upward attack of drug-heat before and after ad ministration of rhubarb. ③ Comparison of the therapeutic effects in the two groups.RESULTS: All 66 patients involved entered the final result analysis. ①The changes of the relevant hormones of the patients with upward attack of drug-heat before and after administration of warm-heat remedy: FT3 and FT4 were decreased as compared with those before treatment [(2.51±1.20),(6.50±2.30); (10.01±3.21), (15.50±6.31) pmol/L], but HS-TSH and cortisol were increased as compared with those before treatment [(8.25 ±3.75),(4.11±1.75) mU/L; (0.56±0.17), (0.43±0.10) μmol/L]. ② The changes of the relevant hormones of the patients with upward attack of drug-heat before and after administration of rhubarb: FT3 and FT4 ywere increased as compared with those before treatment[(4.71 ±1.56), (2.45±1.25); (14.21 ±4.61),(10.21±3.52) pmol/L], but HS-TSH and cortisol were decreased as compared with those before treatment [(6.24±2.25), (8.35±3.51) mU/L; (0.48±0.10),(0.60±0.17) μmol/L]. ③ Comparison of the therapeutic effects in the two groups: The rate of excellenly effect in treatment group was obviously higher than that in control group (33%, 5%).CONCLUSION: The pathophysiological basis of upward attack of drug heat is stress state of the body, the secretions of the pituitary-thyroid axis play a role of physiological protection, the adrenocortical function is hyperactive, and rhubarb can control this stress state through inhibiting the metabolism of the body.

OBJECTIVE: To observe the effects of ginkgolide (GL) on the cerebral blood flow in dogs. METHODS: Dogs anesthetized with sodium pentobarbital were randomly divided into 5 groups, with 4 dogs in each group. Ginkgolide of 4.86, 14.6 and 43.7 mg/kg and Xingling Granule of 0.22 g/kg were administered by gavage to the dogs in each of 4 groups. The dogs in the other group were administered with edible oil (1 ml/kg) as control group. The cerebral blood flow, systolic blood pressure, diastolic blood pressure, mean arterial blood pressure and electro-cardiogram of the dogs were measured at different times after the administration. RESULTS: Ginkgolide of 4.86, 14.6 and 43.7 mg/kg had no obvious effects on the blood pressure and the heart rate. Ginkgolide of 14.6 and 43.7 mg/kg increased the cerebral blood flow 90 minutes after administration, and ginkgolide of 43.7 mg/kg obviously decreased the cerebral vascular resistance 150 minutes after administration. CONCLUSION: Ginkgolide can increase the cerebral blood flow and decrease the cerebral vascular resistance, and it has no obvious effects on blood pressure and heart rate in dogs.
RESUMEN
AIM To extend the approach of the act ion of ganoderma polysacchride on intracellular signal events in T cells. METHODS Laser scanning confocal microscope imaging of the calcium and p H fluorescent indicator dye Fluo-3/AM and SNARF-1/AM were used to determine th e kinetic changes of [Ca2+]i and [pH]i in murine T cells induced b y a ganoderma polysacchride,designated GLB7. RESULTS It was fou nd that GLB7(20 mg*L-1) could increase [Ca2+]i and [pH]i at 1 min were 334.7%±16.4%(n=3)、171.6%±10.4%(n=3) respectively. T he increase in [Ca2+]i induced by GLB7 was due to the influx of extr acellular Ca2+ and intracellular Ca2+ release through both IP3-se nsitive and IP3-insensitive Ca2+ stores, and increase in [pH]i indu ced by GLB7 was relative to Na+/H+ exchange systems and [Ca2+]i. GLB 7 did not influence [Ca2+]i and [pH]i in murine T cells induced by Con A(3 mg*L-1). CONCLUSION Stimulation of the increase in [Ca2+]i and [pH]i may be an important channel for gano derma polysacchrides to achieve their pharmacological actions.
