Objective To investigate the efficacy and safety of isosorbide mononitrate sustained release tables plus vinorelbine and cisplatin in patients with previously untreated advanced non-small-cell lung cancer (NSCLC).Methods One hundred and ten patients with stage ⅢB-Ⅳ NSCLC were randomly assigned to group A (57 cases) and group B (53 cases) by random mumber table.Patients in group A were treated with vinorelbine 25 mg/m2 on the first and eighth day and cisplatin 25 mg/m2 on day 2-4,with transdermally applied isosorbide mononitrate sustained release tables (40 mg,daily for 8 days),and patients in group B were treated with vinorelbine and cisplatin.Response to treatment was assessed by RECIST1.1 and adverse effect was assessed by NCI-CTC(3.0).Results The response rate in group A (58.2％,32/55 patients) was significandy higher than that for patients in group B (30.8％,16/52 patients; x2 =8.120,P =0.004).Median TTP and median OS in group A were longer than those in group B (8.2 vs 5.8 months,x2 =10.684,P =0.001 ; 11.6 vs 9.0 months,x2 =11.231,P =0.001).While,patients with squamous carcinoma showed better response to chemotherapy (RR =2.438,95％ CI:1.136-5.231,P =0.022).Adverse effect difference was not significant between group A and group B,except headache.The rate of grade 1 to 2 headache in group A (34.5％ ; 19 of 55 patients) was significantly higher than that in group B (3.8％ ; 2 of 52 patients; P ＜0.001).Conclusion Use of isosorbide mononitrate sustained release tables combined with vinorelbine and cisplatin may improve overall response,TTP and OS in patients with advanced stage NSCLC.

Objective To explore the clinical features,diagnosi s and prognosis of incontinentia pigmenti.Methods Analyzing and summarizing the clinical characteristic, diagnosis and prognosis of neonatal incontinentia pigmenti in 6 neonatal infants that were hospita- lized in our department during the period from January 1 998 to December 2003 were studied,and some relevant literature were reviewed. Results 1.Three of 6 infants were male which was unusual;2.Four infants had typical skin lesions at birth and 1 case at 6 days old.Four cases had typical 3 stages o f skin lesions including the erythematous and vesicular inflammatory stage,verr ucous lesions and hyperkeratosis stage,macular hyperpigmentation stage,but the re was overlap;3.Four infants were complicated by central nervous system involv ement (two cases presented mental retardation,2 infants were temporary damage). Two cases were complicated by ocular manifestations ( one case had optical nerve atrophy and blind in left eye,the other had severe bilateral retinal lesions); 4.On specific examination 5 infants were diagnosed by skin biopsy.Gene analysis was made in 1 case,but we didn′t find the mutations of NEMO. Conclusions Incontinentia pigmenti is a rare X-linked dominant multisystem disease.It may be misdiagnosed in the initial stages.Except typical clinical features,skin biops y and gene analysis are main evidence for diagnosis.Early detection and interven tion are important for prognosis.

This paper is in order to discussion with the composition and characteristics of Tibetan medicine plant resources, and promote the reasonable protection and utilization of the resources of Tibetan materia medica. Statistical analysis of species, distributions, and others of Chinese endemic seed plant from Tibetan medicine plants and usually used in the clinic of Tibetan medicine. The results showed that there are 523 species (25%) of Chinese endemic seed plant, belonging to 65 families and 162 genera, in about 2 000 varieties of Tibetan medicine plants recorded in relevant literatures. There are 180 Chinese endemic seed plant species (28%) belonging to 42 families and 72 genera from 625 medicine plants usually used in the clinic of Tibetan medicine. Specifically, the most of these Chinese endemic seed plant species are characteristic crude drug used in Tibetan medicine, and mainly or only distributed in Qinghai-Tibet Plateau. And a few species of them were intersected with traditional Chinese medicines (TCM) and other ethnic medicines. In addition, about 10% are listed in China Species Red List. The Qinghai-Tibet Plateau is the most abundant areas of Areal-types of the Chinese endemic seed plant. This is the biological and ecological reason formation the characteristics of Tibetan medicine plant resources. Therefore, strengthen the research of Chinese endemic seed plants used in Tibetan medicine is great significance for the reasonable protection and utilization of Tibetan medicine plant resources.

OBJECTIVETo analyze the relationship between clinical characteristics and prognosis of neonatal cerebral infarction and to draw attention to the disease to improve the long-term outcome through early diagnosis and intervention.

METHODSThe clinical characteristics of 6 confirmed cases were summarized. Perinatal conditions and other factors were analyzed for possible causes of the disease. The survived patients were followed-up for 6-8 months.

RESULTSThe authors diagnosed 6 cases of neonatal cerebral infarction in one year, which accounted for 0.6% (6/969) of all the in-patients in the same time period. Among them 3 cases were confirmed as cerebrovascular malformations by magnetic resonance angiography (MRA), In 1 case the infarction was due to severe bilateral intraventricular hemorrhage, and in another case the disease was related to comprehensive factors such as prematurity, maternal pregnancy induced hypertension and respiratory failure secondary to bronchopulmonary dysplasia (BPD), and in 1 case the cause was undetermined. Four out of the 6 patients presented with varied forms of convulsions, which became the second leading cause for all the neonatal convulsive events (20%). None of the patients had localized neurological signs in the early course except for abnormal muscular tone of some extent. Cerebral ultrasound scanning in 5 out of 6 cases showed positive results. The diffusion-weighted magnetic resonance imaging (DW-MRI) was highly valuable for early confirmative diagnosis. Only one case was found normal within one year of follow-up and all the other 5 cases had unfavorable prognoses of varied severity.

CONCLUSIONNeonatal cerebral infarction is not a rare condition and should be considered as one of the important causes for neonatal convulsion. Imaging study is the main technique for diagnosis. The prognoses were poor for those cases for whom early diagnosis and treatment can not be made or those with widespread cerebral lesions.

OBJECTIVETo investigate the potential effects on cognitive function, prognosis, and neuropeptide levels of patients in response to combination therapy with ornithine aspartate plus naloxone for hepatic encephalopathy.

METHODSEighty-four consecutive patients diagnosed with hepatic encephalopathy were randomly divided into two equal groups. The control group (n = 42) received traditional medical treatment, and the research group (n = 42) received the traditional medical treatment as well as the combination therapy with ornithine aspartate plus naloxone. The supplemental treatment was comprised of daily intravenous injection of 10-15 g ornithine aspartate in 250 ml of 5% glucose plus intravenous drip of 3 mg naloxone in 100 ml of 5% glucose, and was given in 7-day cycles for one or two cycles. The cognitive function of patients was assessed by Hasegawa Intelligence Scale (HDS) and Mini-Mental State Examination (MMSE) questionnaires. The effective rate and time duration from coma to consciousness were recorded. Changes in blood ammonia level, markers of liver function, and neuropeptide levels were measured by standard biochemical assays. Intergroup differences were assessed by the Chi-squared test.

RESULTSThe HDS and MMSE scores of the research group were significantly higher than those of the control group after therapy. The effective rate, time duration from coma to consciousness, blood ammonia, the liver function markers alanine aminotransferase, gamma-glutamyl-transpeptidase and total bilirubin, and the neuropeptides arginine vasopressin and beta-endorphin were remarkably improved after treatment in the research group, as compared with that in the control group.

CONCLUSIONSupplementing the traditional treatment for hepatic encephalopathy with ornithine aspartate plus naloxone combination therapy provides better therapeutic outcome than traditional treatment alone.

OBJECTIVETo investigate the effect of recombinant human interleukin-2 (rhIL-2) activated natural killer cells (rhIL-2-NK) on angiogenesis and cardiac function of rats with myocardial infarction (MI).

METHODSNatural killer cells (NKs) were isolated and activated by rhIL-2 in vitro. Untreated NKs were used as the control, the killing capacity of rhIL-2-NK were evaluated with cytotoxicity assay. Cardiac microvascular endothelial cells (CMECs) were cocultured with rhIL-2-NK. One hour after MI, rats were randomly divided into rhIL-2-NK group, NK group and blank control group and NK, rhIL-2-NK and PBS were injected directly in the infracted myocardium. At the 0, 1(st), 3(rd), 5(th), 7(th) and 20(th)th day after MI, the mRNA expression of monocyte chemotactic protein-1 (MCP-1), Tumor necrosis factor-α (TNF-α) and interleukin-2 (IL-2) were was detected by q-PCR essay. At the end of the therapy, the platelet endothelial cell adhesion molecule-1(CD31) and vascular endothelial growth factor (VEGF) were evaluated through immunohistochemical assay, and the cardiac function observed with echocardiography, homodynamic measurements.

RESULTSThe NKs were isolated successfully and the CMEC were proliferated remarkably by coculturing with rhIL-2-NK (P < 0.01). The mRNA expression of MCP-1, TNF-α, CD31 and rhIL-2, VEGF were significantly upregulated in rhIL-2-NK group than in the PBS control group (P < 0.01). Four weeks after operation, LVEF was significantly higher in rhIL-2-NK group than in the PBS control group [(77.56 ± 15.67)% vs. (41.47 ± 12.21)%, P < 0.05)] and histomorphology assay revealed that the density of microvascular endothelial (MVD) of rhIL-2-NK group was significantly higher than that of PBS control group (17.35 ± 1.82 vs. 4.76 ± 0.92, P < 0.01).

CONCLUSIONSMyocardial injection of rhIL-2-NK could promote angiogenesis and improve cardiac function in MI rats.
