OBJECTIVETo observe the efficacy, median survival time, time to progression, quality of life and adverse effect of gefitinib (IRESSA) in the treatment for refractory advanced non-small cell lung cancer (NSCLC).

METHODSForty-one patients with stage III b to IV NSCLC who had previously treated with 2-7 cycles of platinum-based chemotherapy were enrolled into the study, 85.4% of the patients had received second line chemotherapy. The regimen was oral intake of gefitinib 250 mg once daily until the disease progression or intolerable toxic reaction occurred. The patients were required to receive tumor assessment before the treatment, one month, two months and every three months after IRESSA administration.

RESULTSAll 41 patients were evaluable for therapeutic effect. Partial response rate (PR), stable disease (SD) and progression of disease (PD) was 43.9% (18/41), 34.1% (14/41) and 22.0% (9/41), respectively. No complete regression was observed. The overall response rate was 43.9% (18/41) with a rate of 42.1% in the male and 45.5% in the female (P > 0.05). The disease control rate (PR + SD) was 78.0% (32/41). Twenty-two of the 41 patients (53.7%, 22/41) were still alive with MST of 10.1 months when the follow-up ended in Nov. 2006. TP and MST of dead patients was 2.7 and 5.0 months, respectively. The rate of symptom improvement was 78% for all patients with MST of 13.3 months for PR patients. The performance status (Karnofsky) was improved (20 +/- 5) after 28-day treatment. III-IV degree toxicity was not observed.

CONCLUSIONIRESSA is effective and safe for the advanced NSCLC patients with poor performance status who previously failed in the second or third line chemotherapy.

The morphological index of the seedlings including the plants height, the ground diameter, the leaf amounts, the fresh weight of the whole plant and the ratio of height to diameter was measured and the principal components were analyzed so as to determine the grading index, and stepwise cluster analysis was applied for clustering analysis. Pot experiments were used to measure the indicators of plant growth and development, the yield and the quality. The results showed that the height and ground diameter were determined as the quality indicators of the seedlings grading and the standard quality grading of seedlings of Anoectochilus roxburghii was initially set up, different seeding plants influenced the plants growth and the yield. The ground diameter of the class I was larger than that of the class II and III, so as the yield. The seedling grading had no obvious effect on the internal quality of medicinal materials. The results of the study provide the basis for standard cultivation of A. roxburghii.

OBJECTIVETo study the clinical manifestations and radiological characteristics, diagnostic methods and outcomes of pulmonary mucosa-associated lymphoid tissue-derived(MALT) lymphoma.

METHODSA retrospective review of clinical, radiological and follow-up data of 29 pulmonary MALT lymphoma cases at Shanghai Pulmonary Hospital affiliated to Tong Ji University from January 2002 to June 2010 was performed.

RESULTSAmong these patients, there were 19(65.5%) males and 10 (34.5%) females aged from 27 to 73 (median 53) years old. Common clinical manifestations were cough (51.7%), fever (20.7%), apnea (17.2%), chest pain (17.2%), fatigue (13.8%) and weight loss (13.8%), while 9(31.0%) cases had no symptoms at diagnosis. The characteristics of the chest CT showed that 22 (75.9%) of the cases had patch infiltration or consolidation of the lung, 7(24.1%) of the cases had mass, and 15 (51.7%) unilateral and 14(48.3%) bilateral lesions. Their diagnosis duration varied between 0.5 and 96 months. 18(62.1%) cases were confirmed by surgery (15 open lung and 7 video-assisted thoracic surgery, VAST), 4 (13.8%) by percutaneous lung biopsy, 5 (17.2%) by bronchoscopic biopsy, and 2 (6.9%) by peripheral lymph node biopsy. The treatment methods included surgery, combined chemotherapy, radiotherapy and Chinese herbal medicine. The 1- and 3-year-survival rates were 92.3% and 87.4%, respectively.

CONCLUSIONSPulmonary MALT lymphoma is atypical in clinical manifestations and radiological characteristics, and easy to be misdiagnosed. Local diseases are mainly treated by operation while extensive diseases receive combined chemotherapy. A proper diagnosis is mainly based on pathological biopsy. Patients with MALT lymphoma have a favorable outcome. Poor prognosis may be connected with poor performance status and long diagnosis duration.

OBJECTIVETo study the expression of MUM-1/IRF4 and its significance in follicular lymphoma.

METHODSNinety-eight cases of follicular lymphoma were enrolled into the study. They were graded according to the 2008 WHO criteria. The expression of MUM-1/IRF4 protein and other markers (CD10, bcl-6, bcl-2 and Ki-67) was studied using tissue microarray and immunohistochemistry.

RESULTSAmongst the 98 cases studied, there were 24 grade 1 cases, 30 grade 2 cases, 26 grade 3A cases and 18 were grade 3B cases. The rates of expression of MUM-1/IRF4, CD10, bcl-6, bcl-2 and Ki-67 (≥ 25%) were 39.8% (39/98), 62.2% (61/98), 80.6% (79/98), 87.8% (86/98) and 50.0% (49/98), respectively. MUM-1/IRF4 predominantly expressed in high-grade follicular lymphoma and showed a significantly positive correlation with lymphoma grade (r = 0.628, P = 0.000) and Ki-67 index (r = 0.473, P = 0.000). MUM-1/IRF4 expression had a significantly negative correlation with CD10 expression (r = -0.597, P = 0.000), but no correlation with bcl-6 and bcl-2 expression.

CONCLUSIONSMUM-1/IRF4 expression is significantly higher in high-grade follicular lymphoma, indicating that these cases have a high proliferative activity, more aggressive behavior and poorer prognosis. MUM-1/IRF4, when strongly expressed, is another helpful marker for the diagnosis of high-grade follicular lymphoma.

Objective To evaluate the efficacy and safety of isotretinoin and viaminate for the treatment of moderate to severe acne vulgaris.Methods A multiple-centre,double-blind,double-analog comparative clinical trial was conducted.Patients diagnosed with moderate to severe acne by GAGS (global acne grading system) were randomly divided into isotretinoin group (10 mg,bid) and viaminate group (50 mg,tid);treatment was done for a total of 6 weeks.All subjects were evaluated before treatment,and at 2,4,6 weeks after the initiation of treatment,for evaluation of lesion count,and for observation of thera- peutic effects and side effects.Results A total of 217 patients were enrolled this trial,of which,213 could be evaluated in a FAS (Full Analysis Set) analysis and 200 in a PPS (per protocol) analysis.There was no significant difference in the efficacy at 2,4,6 weeks after the initiation of treatment between the isotretinoin group and viaminate group (6.0% vs 5.0%,29.0% vs 20.0%,57.0 % vs 51.0 %,respectively). However,the inflammatory papules and pustules decreased more rapidly in the isotretinoin group than in the viaminate group at each of the follow up evaluations (all P＜0.05).There was no obvious difference in the rate of clearance of comedones and nodules between the two groups.Both the occurrence rate (68.81% vs 36.53%,P＜0.001) and severity (P＜0.05) of side effects were higher in the isotretinoin group than in the viaminate group.The main adverse events included mouth dryness,dizziness,etc,occurred more fre- quently in the isotretinoin group than in the viaminate group.Conclusion For the treatment of moderate to severe acne,the efficacy of isotretinoin is similar to that of viaminate;however,isotretinoin has more imme- diate effect with more side effects than viaminate.

The current status of the domestic manufacturing and sales markets of Anoectochilus roxburghii were investigated and analyzed in the study. Some problems in the A. roxburghii industry were revealed and a variety of sustainable development countermeasures were also proposed. The main problems of A. roxburghii industry are the lack of protection for wild resources, the lag in the speed of variety breeding, the insufficient research on the quality systems, the low level of industry and product innovation capability, as well as the relatively low market cognition and brand competence. Therefore, strengthening the protection for breeding resources, establishing a dynamic monitoring system, promoting the variety breeding, constructing a propagation system for improved varieties, enhancing the quality of medicinal herbs, accelerating the adjustment of product structure, upgrading the industry technology, strengthening brand competence and expanding the market, will be the effective methods to realize the sustainable development of A. roxburghii industry.
