Objective To investigate the changes of monoamine neurotransmitters of the brain in two tat models of morphine dependence,and to explore the effects of sinomenine on morphine dependence.Methods A physical dependent rat model was established with morphine at a gradually increasing dosage and the withdrawal syndrome was scored after naloxone precipitation.The conditioned place preference(CPP)in rats induced by morphine was used to investigate psychic dependence in rots.Contents of norepinephrine(NE),dopamine(DA)and serotonin(5-HT)in hypothalamus of rats were assayed with a fluorescent method.Results 1.In naloxone precipitated withdrawal test of in morphine-dependent rats,after morphine withdrawal,the rats presented marked with drawal symptoms and signs,their withdrawal scores were significantly increased,and the levels of NE and 5-HT in hypothalamus of the rats were significantly increased than the control group Ⅰ(7.07±1.406μg/g wet tissue and 1.15±0.346 μg/g wet tissue,respectively,P<0.01),but the content of DA was markedly reduced than the control group Ⅰ(0.28±0.121 μg/g wet tissue,P<0.05).2.In CPP model,morphine caused a marked place preference in rats and the levels of DA and 5-HT in hypothalamus were significantly increased than the control group Ⅱ(1.13±0.359 μg/g wet tissue and 1.23±0.343μg wet tissue,respectively,P<0.01),but the content of NE was not significantly changed(3.28±1.098 μg/g wet tissue,P>0.05).Sinomenine could significantly inhibit the withdrawal syndrome and development of CPP induced by morphine in rats,and could suppress the rising of monoamine neurotransmitters of the brain in two morphine dependent models in rats.Conclusion In the physical dependent model induced by morphine in rats,the rising of NE and 5-HT in the rat brain were significant,but in CPP model induced by morphine in rats,the levels of DA in the rat brain were enhanced predominately.Sinomenine could inhibit the withdrawal syndrome and development of CPP in rats,and regulate and improve the function of monoamine nerve system.

AIM: To evaluate the clinical feature of 9 patients harboring mitochondrial DNA ( mtDNA ) G11778A mutation with Leber hereditary optic neuropathy ( LHON) .
●METHODS: Nine LHON patients were enrolled and followed- up between 2012 to 2015 in Shenzhen Eye Hospital, clinical data were collected and analyzed.
●RESULTS: Six cases had maternal inheritance history ( 67%) . Three were sporadic cases. The patients aged from 9 to 43 years old, with average age of (22. 00±9. 42) years. Simultaneous onset with both eyes was in 5 cases (56%). Successively onset was in other 4 cases (44%). The ratio between male and female was 2:1. In the last follow-up, the visual acuity was finger counted in 2 eyes (11%), 0. 01-0. 1 in 12 eyes (67%), 0. 12-0. 4 in 2 eyes (11%),≥0. 4 in 2 eyes (11%). All patients had pale disc and clear boundary. ln the Humphrey visual field examination, 10 eyes had typically cecocentral or paracentral scotoma, 8 eyes had diffuse visual field defect.
●CONCLUSION: ln the 9 LHON patients with mtDNA G11778A mutation, simultaneous onset cases were more than successively onset cases within 1y cases. In most cases, LHON patients kept stable visual acuity. Rare cases had a raise in visual acuity within 1y. Majority patients had typically cecocentral or paracentral visual field scotoma. In the last stage of LHON, visual field present diffused defect. The secondary affected eye was similar performed defect as the former one.

OBJECTIVE:To investigate the characteristics and factors of ADR caused by Chinese patent medicine(CPM)and to provide reference for rational drug use and safety evaluation in the clinic. METHODS:158 cases of ADR caused by CPM collect-ed from our hospital during Jan.2009-Dec.2014 were analyzed. RESULTS:The occurrence of ADR caused by CPM was related to patient’s age,route of administration,category of drugs,irrational drug-use and so on. The incidence of ADR in patients over the age of 60 was the highest (31.01%),the largest number of ADR were caused by intravenous injection (79.11%),ADRs were most likely caused by blood-regulating preparation and dissipate blood stasis preparation (79.75%);ADR manifested as lesion of skin and its appendents(43.01%),followed by gastro-intestinal injury(16.06%)and whole-general injury(10.36%). The severe ADR was anaphylactoid reaction;after symptomatic treatment,the prognosis is good. CONCLUSIONS:According to syndrome differentiation and individual difference,CPM should be used rationally,and great importance should be attached to drug use moni-toring to reduce the incidence of ADR.

We report a case of cutaneous metastasis of thymic carcinoma in Korean. A 44-year-old female, who had been diagnosed as thymic carcinoma and treated with total thymectomy and post-operative radiation therapy, presented grouped erythematous papules on the left chest. CT scans revealed metastatic lesions in the left pleura and abdominal cavity. Histopathologic examination of skin biopsy showed extensive infiltration of malignant cells in dermis and subcutis. The morphology of infiltrating cells was similar to that of tumor cells from primary thymic carcinoma specimen. The results of immunohistochemical study for skin biopsy were consistent with the features of non-neuroendocrine thymic carcinoma. Histopathologic and immunohistopathologic similarity between cutaneous lesion and previous tumor suggested that malignant cells in the skin lesion could originate from progressing thymic carcinoma.

Pigmented fungiform papillae of the tongue(PFPT) is a rare benign pigmentary disorder of the tongue. In dark-skinned individuals, PFPT appears to be relatively common, whereas this entity is seldom reported in fair-skinned people and Asians. Although the relevance to systemic conditions has been suggested in several reported cases, the etiology and pathogenesis of this entity are not yet clearly defined. We report two cases of PFPT in young Korean females. Clinically both patients presented with asymptomatic pigmentary lesions confined to fungiform papillae of the tongue, which had been detected several months ago. Histopathologic findings revealed increased melanophages in the subepidermal area within the fungiform papillae.

Lentigo maligna melanoma(LMM) is the least common type of melanoma. LMM is almost exclusively located on sun-exposed skin of the head and neck. We describe a case of lentigo maligna melanoma evolved from lentigo maligna in 82-year-old man. Five years ago, the patient developed a brownish pigmented lesion on the left cheek. The lesion progressed slowly, and several months ago, a black pigmented patch was developed in the periphery of the brownish pigmented patch. Histopathologic examination of the lesions revealed findings consistent with lentigo maligna and lentigo maligna melanoma.

PURPOSE: This study was conducted to assess the nutritional status of female marriage immigrants attending Korean language class in Gwangju, Korea by analyzing daily food and nutrient intake. METHODS: Eighty-three female immigrants completed a survey. Anthropometric measurements were obtained, and dietary food intake was assessed using a 1-day 24 hour recall method. RESULTS: The average length of residence in Korea was 5.3 years, and mean age of subjects was 31.0 years old. The home countries of subjects were Vietnam (50.6%), China (24.1%), Philippines (13.3%), and others (12%). Due to the length of residence, there were significant differences in body weight (p < 0.05), BMI (p < 0.05), percent body fat (p < 0.05), and diastolic blood pressure (p < 0.05). The subjects who were 30~49 years old consumed more vegetables and less seaweed than the subjects who were 20~29 years old. The other kinds of consumed foods were similar among groups in different age groups or lengths of residence in Korea. Average energy intake of subjects was 1,641.0 Kcal. The group with less than 5 years of residence showed higher cholesterol intake than the group with 5 or more years of residence in Korea (p < 0.05). There was no significant difference in nutrient intake between the groups of different age or length of residence. There was a positive association among dietary cholesterol intake and consumption of eggs, milk. and dairy products, and blood pressure. CONCLUSION: The study shows that length of residence affects rate of obesity and nutritional status. Further extensive research is needed to understand the effect of dietary changes and nutritional status of female marriage immigrants as well as for their successful adaptation to develop a more active and long-term nutrition education program.
