1.Study on the relationship between the expression of CA242 and CD_(44v6) and their clinicopathologic significance in gastric carcinoma
Cancer Research and Clinic 2009;21(12):815-817
Objective To investigate the expression of CA242 and CD_(44v6) protein in gastric cancer (GC) and its clinical significance. Methods Immunohistochemical staining was used to detect the expression of CA242 and CD_(44v6) protein in 120 cases of GC, 30 cases of gastric epithelial dysplasia and 20 cases of normal gastric mucosa. The pathological feature of GC and clinical follow-up data was also analysed. Results The positive rate of CA242 and CD_(44v6) was 79.2 % and 81.7 %, respectively in primary GC. The positive rate of CA242 and CD_(44v6) in GC was higher than that in epithelial dysplasia and normal gastric mucosa (P <0.05). The expression of CA242 and CD_(44v6) was closely related to infiltration of serosa, metastasis of lymph node and prognosis of patients (P <0.05). Conclusion These data suggest that the expression of CA242 and CD_(44v6)is closely related to carcinogenesis, metastasis and survival rate in GC. CA242 and CD_(44v6) may be prognostic indicators of GC.

AIM: To investigate the clinical effect and side-effects of paroxetine in the treatment of generalized anxiety (GA). METHODS: Ninety patients who met Chinese classification and diagnostic criteria of mental disorders, 2nd Rev Ed (CCMD-2-R) criteria for GA were randomly divided into paroxetine group of 30 patients (M 12, F 18; age 40 a±s 13 a) which was treated with paroxetine 20-40 mg, po, qd or bid, benzodiazepines group of 30 patients (M 13, F 17; age 37 a±13 a) among them, 16 patients were treated with alprazolam 0.4-0.8 mg, po, bid or tid, 14 patients were treated with clonazepam 1-2 mg, po, bid or tid and placebo group of 30 patients (M 11, F 19; age 37 a±13 a) which was treated with placebo 1 tablet, tid for 12 wk. Effects were evaluated with Hamailton anxiety scale (HAMA), self-rating anxiety scale (SAS), clinical global impression scales (CGI) and treatment emergent symptoms scale (TESS), before and after the wk 2,4,8,12 of treatment. RESULTS: The excellent response rates of paroxetine group and benzodiazepines group were 90 % and 50 % (P<0.01). The side-effects of paroxetine group were dry mouth, constipation, nausea, but those were less than that of benzodiazepines group. CONCLUSION: The study suggests that paroxetine is an effective drug for the long treatment of GA and the side-effect is less.

AIM: To compare the effects between topiramate and slow-release sodium valproate in treating refractory epilepsy. METHODS: Topiramate group of 39 patients (M 21, F 18; age 28 a± s 20 a) was compared with sodium valproate group of 41 patients (M 22, F 19; age 27 a±17 a) in antiepileptic effect of refractory epilepsy. Adult's and children's dosages of topiramate were increased gradually about 200 mg*d-1 and 4 mg*kg*d-1 respectively during about 2 mo, po, bid, for 6 mo as a course. Adult's dosage of slow-release sodium valproate was 0.5-1 g*d-1, and children's was increased gradually to total dosage: 15-30 mg*kg*d-1, po, qd or bid (morning or morning and noon), for 6 mo as a course. Effects were analysed between these two drugs after treatment 4 and 6 mo. RESULTS: Simple and complex partial seizures with or without secondary generalized seizure, in topiramate group were much more improved than these in sodium valproate group 6 mo after treatment. Four patients of topiramate group appeared temporary adverse reactions of central nervous system, such as tiredness, sleepiness and distraction, but one patient of sodium valproate group had severer decreased function of bone marrow. CONCLUSION: Topiramate is one of effective antiepileptic drugs and superior to slow-release sodium valproate. There are the apparent absence of any effects of topiramate on the bone marrow and on indexes of liver and kidney.

Objective To investigate the effects of telmisartan on the blood glucose, blood lipid, blood insulin, and insulin resistance in the hypertensive patients with dyslipidemia, and also its effect on controlling blood pressure. Patients and Methods A total of 96hypertensive patients (34 females, 62 males) with dyslipidemia were included (mean age 51.2±9.6, range 42-65 years). Patients were randomized to receive either telmisartan 80 mg/day (n=46) or enalapril 10 mg/day (n=50) for 6 months. The levels of blood pressure (BP), heart rate (HR), and biochemical data were measured before therapy and at the end of the 3-month treatment and 6-month treatment, respectively. Meanwhile, insulin resistance was evaluated by using a homeostasis model assessment of insulin resistance (HOMA-IR) and insulin sensitivity (HOMA-IS). Results In the telmisartan group, the mean blood pressure was obviously lower than that of pre-therapy (P<0.05), and the levels of triglyceride (TG), HOMA-IR, and HOMA-IS were all obviously lower than those of pre-therapy and of the enalapril group at the end of the 3-month-treatment period (P<0.05). After 6 months of treatment, the levels of TG, HOMA-IR, and HOMA-IS in the telmisartan group were significantly lower in comparison with those of pre-therapy, the enalapril group (P<0.01), and 3-month-treatment (P<0.05). Post-prandial12 hour blood glucose (P2HBG) in the telmisartan group decreased significantly after 6-month treatment compared with that of pre-therapy and the enalapril group (P<0.05). The level of high density lipoprotein (HDL) cholesterol was significantly higher after 6-month treatment in the telmisartan group than with pre-therapy and the enalapril group(P<0.05). Conclusions Telmisartan could not only control blood pressure steadily and effectively, but also decrease blood TG, increase HDL cholesterol and insulin sensitivity, and lower insulin resistance.

Objective To investigate the inhibitory effect of Lycium barbarum polysaccharide ( LBP) on the tumor growth and metastasis in MMTV?PyMT mouse model of breast cancer. Methods The population of MMTV?PyMT trans?genic mice was expanded and identified. 8?week old MMTV?PyMT?positive female mice were randomly divided into LBP group and control group, 8 mice in each group. The mice of LBP group were given LBP treatment (50 mg/kg, i. p. ), and the control group was given normal saline in the same volume, once every 2 days for 4 weeks. The tumor size was measured every two days. The mice were killed at 4 weeks after treatment, the lungs were removed and fixed in Bouin′s solution to observe the number of metastatic nodules, and tumor tissues were used for immunohistochemical examination of tumor cell proliferation and vascular density. Results The tumor formation rate was 100% in the MMTV?PyMT?positive mice. The tumor weight of LBP group was 4?208 ± 0?4463 g, significantly lower than the 6?477g ± 0?3724 g in the control group (P<0?005). The number of pulmonary nodules of the LBP group was 12 ± 1?155, significantly less than that of the control group (20 ± 2?745) (P<0?05). The immunohistochemical examination using Ki67 and CD31 staining showed that tumor cell proliferation and microvessel density of the LBP group were significantly less than the NS group. Conclusions LBP inhibits breast cancer growth and metastasis through the inhibitory effect on tumor growth and metastasis, inhibition of tumor cell proliferation and angiogenesis in MMTV?PyMT mice. These mice can be used as an ideal model for studies on antitu?mor drug development for the treatment of breast cancer lung metastasis.

Objective To conduct comparative study on the analgesic and anti-inflammatory effects as well as the acute toxicity of yunaconitine and 8-deacetyl-yunaconitine isolated from the processed products of Aconiti Knsnezoffii Radix.Methods The methods of hot plate test and writhing test were used to evaluate the analgesic effect. Anti-inflammation action was observed by the models of auricle swelling caused by dimethylbenzene. LD50 was determined by the method of Bliss.Results Yunaconitine and 8-deacetyl-yunaconitine have analgesia effect on the pain caused by hot-plate, but there were no statistically significant difference. The pain caused by acetic acid had obvious analgesic action. High and low dose of yunaconitine could significantly reduce the number of mice body torsion and extend the incubation period of pain in mice. The effect of 8-deacetyl-yunaconitine was remarkable only in the high dose. Compared with solvent group, there were little differences in inhibiting effect of auricle swelling caused by dimethylbenzene, and anti-inflammatory action was not exact. The poisonousness of yunaconitine was nearly 20 times of 8-deacetyl-yunaconitine.Conclusion Yunaconitine and 8-deacetyl-yunaconitine may be the analgesic medicine for peripheral analgesic effect. The poisonousness of 8-deacetyl-yunaconitine is less than yunaconitine, the effect is remarkable to the pain caused by acetic acid, and the security is high.
