OBJECTIVETo report the experiences of the diagnosis and treatment of primary lymphoma of the small intestine (PSIL).

METHODSThe clinical data of 15 patients with PSIL treated from January 2003 to July 2007 was investigated retrospectively. Of the 15 cases, 9 patients were male and 6 were female, the average age was 51.6 years (range, 18 - 73 years). Data of gender, age, clinical manifestation, laboratory examination, imageology examination, diagnosis and treatment of the patients was reviewed.

RESULTSThe most common clinical manifestations were as follow: abdominal pain, abdominal lump, bowel obstruction, gastrointestinal hemorrhage and athrepsy. Serum tumor markers were checked normal. All the 15 cases were found with tumor by spiral CT, and 12 cases were diagnosed as PSIL. Eleven cases were given Ba-meal examinations, and positive results was found in 4 cases, and only 1 case was considered to be PSIL. All the 15 patients received operation. All the patients were diagnosed as non-Hodgkin lymphoma (NHL) by postoperative pathology (8 patients as diffuse large B-cell lymphoma, 5 as mucosa associated lymphoid tissue type B cell lymphoma and 2 as enteropathy-type intestinal T cell lymphoma). No perioperative death occurred. Ten patients received adjuvant chemotherapy with the regimen of CHOP (cyclophosphamide + epirubicin + vincristine + prednisone) after the operation. Fourteen cases were followed-up for a mean time of 30 months (range, 6 - 52 months). The 1- and 3-years survival rate was 85.7% and 57.1%, respectively.

CONCLUSIONSPSIL has no specific clinical manifestations, the diagnostic rate with barium study is low, spiral CT scan is a promising diagnostic method for PSIL. Operation combined with chemotherapy is important for PSIL.

OBJECTIVETo explore the efficacy and feasibility of dog days moxibustion plaster therapy in treatment of allergic rhinitis of different patterns/syndromes.

METHODSAllergic rhinitis of lung deficiency and invasion of cold, spleen qi deficiency and kidney yang deficiency, 56 patients for each pattern/syndrome were randomized into a plaster therapy group and a nasal spray group, 28 cases in each one. In the plaster therapy group, according to the pattern/syndrome differentiation, with literature retrieval method, 3 acupoints of high frequency utility in clinic were selected as one group in acupoint plaster therapy. For lung deficiency and invasion of cold pattern/syndrome, Feishu (BL 13), Fengmen (BL 12) and Hegu (LI 4) were selected. For spleen qi deficiency pattern/syndrome, Pishu (BL 21), Zusanli (ST 36) and Dazhui (GV 14) were selected. For kidney yang deficiency pattern/ syndrome, Shenshu (BL 23), Dingchuan (EX-B 1) and Bailao (EX-HN 15) were selected. Separately, on July 13, 2013, July 23, 2013, August 2, 2013 and August 12, 2013, the aucpoint plaster therapy was applied, 2 to 4 h (1 to 2 h for children) each time. In the nasal spray group, beclometasone dipropionate aqueous nasal spray, 2 presses one nostril each time, 2 to 3 times a day, continuously for 4 weeks. The symptom score and efficacy were compared before and after treatment in the patients of the two groups.

RESULTSThe symptom scores of 3 patterns/syndromes were all apparently improved after treatment as compared with those before treatment in the patients of the two groups (all P<0.05), and the result in the plaster therapy group was better than that of the nasal spray group (P<0.05, P<0.01). For lung deficiency and invasion of cold pattern/syndrome, the total effective rate was 87.3% (20/24) in the plaster therapy group, better than 84.6% (22/26) in the nasal spray group (P<0.05). For spleen qi deficiency pattern/syndrome, the total effective rate was 83.3% (20/24) in the plaster therapy group, obviously better than 76.9% (22/26) in the nasal spray group (P<0.05). For kidney yang deficiency pattern/syndrome, the total effective rate was 79.2% (19/24) in the plaster therapy group, better than 76.9% (22/26) in the nasal spray group (P<0.05).

CONCLUSIONThe dog days moxibustion plaster therapy achieves definite efficacy on allergic rhinitis at the acupoints selected based on the differentiation of different patterns/syndromes and the efficacy is better than beclometasone dipropionate aqueous nasal spray.

Objective To assess the efficacy and adverse-event profile of monotherapy oradd-on therapy with topiramate in elderly patients with epilepsy. Methods A multicenter, prospective,open-label, observational study of topiramate, for either monotherapy or add-on therapy, was performedamong 119 elderly patients with epilepsy in the Outpatient Department of Neurology of 52 generalhospitals in China. After the baseline evaluation, topiramate was given at the target dose of 200 mg/dayover an 8-week titration period. In the subsequent 12-week maintenance period, the topiramate dose wasadjusted (200-300 mg) according to the clinical results. The patients were followed up for 6 months, withmonthly visits and regular physical, neurological and laboratory examinations. Results After themaintenance period, 106 patients (89.1%) showed a seizure frequency reduction by 50% or greater fromthe baseline, among whom 65 patients(93.8%)received the monotherapy and 54(83.8%) had the add-ontherapy. Topiramate monotherapy and add-on therapy resulted in a complete seizure control in over 50%of the patients with various types of seizure. In patients with disease course less than 1 year, between 1and 3 years, between 4 and 6 years, and over 6 years, topiramate monotherapy resulted in seizurereduction by 92.86%, 91.67%, 100%, and 94.44%, and the add-on therapy reduced the seizure by80.00%, 85.71%, 70.00%, and 86.36%, respectively. When combined with carbamazepine, valproatesodium, phenytoin, phenol barbital, and diazepam, the total effective rate oftopiramate was 79.41%,87.50%, 85.71%, 0%, and 80.00%, respectively. Topiramate, especially in monotherapy, caused onlymild or moderate adverse effects. Conclusion Topiramate is effective and safe for either monotherapyor add-on therapy of epilepsy in elderly patients. The types of epilepsy, disease course, or the drugs usedin the add-on therapy do no obviously affect the efficacy of topiramate for seizure control.

Objective:To assess the degree of labor pain at the time of intraspinal labor analgesia in women influencing the incidence of cesarean delivery.Methods:Five hundred and ninety patients were enrolled in the study and divided into 3 groups in the light of numeric rating scale (NRS).The woman was with singleton pregnancies, with cervical dilatation of less than 4 cm and vertex fetal presentations.Namely, L group:1-4;M group:5-7;H group:8-10, respectively.The EA procedure was performed at the lumbar spine between 2-3 or 3-4.We inserted a catheter into the epidural space started with 1.0% carbonated Lidocaine to make the volume 5 mL.After the block plane arising, injected a mixture of 0.1% Ropivacaine co-administered with 5 μg of Sufentanil to make the total volume 10 mL in all cases, and connected the patient controlled epidueal analgesia (PCEA) thirty minutes later.The CSEA procedure was started with an intrathecal standard mixture of 0.1% Ropivacaine co-administered with 3 μg of Sufentanil to make the total volume 3 mL in all cases, then connected the PCEA ninety minutes later.To observe and record the NRS score when analgesia was performed.The time of the first stage of labor, the time of the second stage of labor and the way of delivery were recorded in our study respectively.Results:There was no statistically significant differences among the three pain groups in the NRS score after 30 min, dilatation, duration of first stage of labor and duration of second stage of labor, respectively.There was no statistically significant differences among the three pain groups in the incidence of instrumental delivery and cesarean delivery.Conclusions:There is no effect of the degree of labor pain at the time of intraspinal labor analgesia in women on the incidence of cesarean delivery.

AIMTo explore the effect and the possible mechanism of ginsenoside Rb1 on beta-amyloid peptide (beta-AP)(25-35) -induced tau protein hyperphosphorylation in cortical neurons.

METHODSWestern blotting and immunocytochemical staining were used to detect tau phosphorylation level, total tau and glycogen synthase kinase-3beta (GSK-3beta) in cortical neurons.

RESULTSAfter exposure to beta-AP(25-35) (20 micromol x L(-1)) for 12 h, the levels of tau protein phosphorylation in the sites of Ser 396, Ser 199/202, Thr 231 and total tau were raised. Meanwhile, the expression of GSK-3beta also increased. Pretreatment with ginsenoside Rbl or lithium chloride, a specific inhibitor of GSK-3beta, markedly reduced beta-AP(25-35)-induced tau hyperphosphorylation and the expression of GSK-3beta.

CONCLUSIONGinsenoside Rb1 can attenuate beta AP(25-35)-induced tau protein hyperphosphorylation in cortical neurons by inhibiting the expression of GSK-3beta.

OBJECTIVETo investigate anti-tumor effect of the recombined adenovirus encoding NK4 gene regulated by human telomerase reverse transcriptase (HTERT) promoter (Ad HTERTp-NK4) on human colon cancer.

METHODSColon cell line HCT116 was infected with Ad HTERTp-NK4. NK4 expression was determined by RT-PCR and Western blot. The cell-growth inhibition rate and the invasive capacity of cells were evaluated by MTT method and reconstituted basement membrane invasion assay. The model of subcutaneous tumor was generated by injection of HCT116 cells into the dorsum of nude mice. Ad HTERTp-NK4 was injected around the tumor tissues, and tumor growth was observed.

RESULTSNK4 gene was highly expressed in infected HCT116 cells. The cell growth inhibition rate and the invasive inhibition rate in Ad HTERTp-NK4 cells were 47.14% and 40.63% respectively, which were significantly higher than those in the control cells (2.75% and 2.31%, P<0.05). Tumor growth was significantly inhibited in mice injected with Ad HTERTp-NK4, and the tumor growth inhibition rate was 47.3%, which was significantly higher than that in the controls (4.6%, P<0.05).

CONCLUSIONAd HTERTp-NK4 can inhibit tumor growth and decrease the invasive capacity of tumor cells, which makes it an ideal candidate for new gene therapy for colon carcinoma.

OBJECTIVETo explore the factors related to the prognosis of colorectal cancer (CRC) and to establish a prognostic model for evaluating the prognosis of the patients with CRC.

METHODS370 cases with CRC were selected in the study and clinical/pathological factors were collected and patients were followed. Kaplan-Meier method was used to calculate survival rate. Log-rank test and proportional-hazards regression model (Cox model) were used for univariate and multivariate analysis. Log cumulative hazards function plot was used to test Cox model proportional-hazards assumption (PH assumption). Prognostic index (P1) was calculated based on the results of multivariate analysis.

RESULTS(1) One-year, three-year and five-year survival rates were 90.5%, 78.3% and 76.5% respectively. (2) Lymphatic metastasis, Duckes classification and therapeutic measure were independent prognostic factors of CRC and all passed PH assumption. (3) Patients with different PI were classified into 3 groups and there were significant differences noticed in survival rates (P < 0.001). (4) Individual survival rate was evaluated based on the prognostic Cox model and PI.

CONCLUSIONLymphatic metastasis, Duckes classification and therapeutic measure were independent prognostic factors of CRC. To test PH assumption of the factors, selection of Cox model was essential. Cox model and PI seemed to be available in predicting the long term survivrate of patients with CRC.
