Background and purpose. Chemotherapy is a standard treatment for patients with advanced stage non-small cell lung cancer (NSCLC) However, platinum based chemotherapeutic regimen haves high toxicity profile to normal tissues. Lobaplatin (LBP) is a new third-generation antitumour platinum drug. Studies abroad have shown that Iobaplatin has an anticancer activity similar to cisplatin with better tolerance and is more effective for those who are resistant to cisplatin. This study was aimed to observe the effectiveness and toxicities of lobaplatin combined with vinorelbine (NVB) for the treatment of advanced NSCLC. Methods: Sixty-four patients pathologically diagnosed as clinical stage Ⅲ_B-Ⅳ NSCLC who did not receive treatment before, were randomly assigned to two groups. NL group (NVB+LBP): LBP at a dose of 30 mg/m~2 intravenous infusion on day 1, and NVB at a dose of 25 mg/m~2 intravenous infusion on days 1 and 8. NP group (NVB+DDP): Cisplatin (DDP) at a dose of 30 mg/m~2 intravenous infusion on day 1, 2 and 3 and NVB at a dose of 25 mg/m~2 intravenous infusion on days 1 and 8. Treatments were repeated every 21-28 days for 3 cycles. Results: For 34 patients of NL group, there were CR (1 cases), PR(13 cases), NC(15 cases), and PD(5 cases). The overall response rate (RR) was 41.2%, disease control rate (DCR) was 85.3%. In NP group: RR was 43.3%, DCR was 83.3% (X~2=0.05, P>0.05). Median overall survival time was 8.6 months and 8.9 months for NL group and NP group, respectively. The main toxicities in NL group were myelosuppression. Digestive toxicity such as anorexia, nausea,vomiting were less than those in the NP group (X~2=7.43, P<0.05), Peripheral hour,toxicity, serious liver and renal toxicity were not observed in NL group. Conclusion: Compared with cisplatin plus vinorelbine, domestic lobaplatin with vinorelbine yielded similar efficacies for NSCLC, but had less toxicity and well tolerate.

Background Proliferation of the human Tenon capsule fibroblasts(HTFs) is a main cause of failure of filtering surgery.To search the drug of inhibiting the growth of the HTFs is essential for the improvement of successful rate of filtering surgery.Objective The aim of this study was to investigate the inhibitory effect of apigenin on HTFs and its mechanism.Methods Human Tenon capsular tissue was obtained during the strabismus correction surgery.HTFs was primarily cultured using explant method and identified using vimentin by immunochemistry.The 3-5 generation of cells were incubated to 96-well plate.Apigenin of 0,20,40,80,160 μmol/L was added into the medium,respectively,for 24,48,72 hours,and the proliferation of HTFs was detected by sulfonyl chloride (SRB) at the wavelength of 560 nm (A560).Bromodeoxyuridine (BrdU) of 10 μg/L was added to culture the cells for 48 hours to calculate the labeling rate of BrdU.The morphology of the cells was observed using Hoechst 33258 staining,and apoptosis and cells cycle were evaluated by flow cytometry.Results Cultured cells grew well with the positive response for vimentin,showing the green fluorescence in cytoplasm.SRB assay showed that the A560 value was gradually declined with the increase of the dosage of apigenin and prolong of time (Fgroup =480.306,P =0.000 ; Ftime =555.144,P =0.000).The labeling rate after 0,40,80 μmol/L apigenin acted for 48 hours was (87.860 ±0.632)％,(61.520±4.306)％ and (23.480±4.472)％,showing a significant difference among the three groups (F =299.347,P =0.000).The labeling rate of HTFs for BrdU was significantly decreased in the 40 and 80 μmol/L apigenin groups compared with the 0 μmol/L apigenin group (P＜0.05).Hoechse 33258 staining found that the number of the HTFs was gradually decreased and the cell number of karyopyknosis and nuclear deformation was increased with the increase of apigenin dosage.Percentage of cells in G0/G1 phase were raised and that in S and G2/M phase were declined in the higher dosage apigenin group,with a significant difference among the different groups (FG0/G1 =58.621,P=0.000;Fs =32.357,P=0.001 ;FG2/M =83.998,P=0.000).In the 72nd hour after acted by 0,40,80,160 μmol/L apigenin,the apoptosis rate of HTFs was (4.77±0.21) ％,(13.24±1.35)％,(18.33±1.86) ％,(31.58 ± 2.77) ％,respectively,with a statistically significant difference among the four groups (F =204.791,P＜0.05).Conclusions Apigenin restrains the growth of HTFs by evoking G0/G1 cell cycle arrest and inducing apoptosis in a dosage-and time-dependent manner.

In order to test the equilibrium solubility of puerarin in different solvents and solubilizer,cilia toxicity and irritation of these excipient, the balance method, toad in the ciliary body toxicity and rat nasal mucosa irritation were used respectively. Results showed that puerarin solubility was 56.44 g x L(-1) in combined solvent of 30% PEG200 and 10% Kolliphor HS 15. With normal saline solution as negative control and sodium deoxycholate as positive control, the effects of 30% PEG200, 30% PEG 400, 10% Kolliphor HS 15 and combination of 30% of PEG200 and 10% Kolliphor HS 15 on toad palate cilium were observed and cilia movement duration was recorded. The results indicated that there was no significant difference in cilia movement duration among 30% PEG200, 10% Kolliphor HS 15 and normal saline group. The rats long-term nasal mucous membrane irritation of 30% PEG 400, 10% Kolliphor HS 15, which had no cilia toxicity, was studied, with normal saline solution as negative control. There were no significant difference revealed on rat nasal mucosa epithelial thickness among 30% PEG 400, 10% Kolliphor HS 15 and normal saline. Above researches showed 30% PEG 400, 10% Kolliphor HS 15 was ideal for solubility of puerarin nasal drops and showed a lower cilia toxicity and irritation, and can be used as the solvent and solubilizer of puerarin nasal drops.

OBJECTIVETo investigate the effects of intensive insulin therapy on insulin resistance(IR) and serum proteins after radical gastrectomy.

METHODSTwenty-two gastric cancer patients were randomly divided into the control (n=11) and intensive insulin therapy group (n=11), and underwent distal radical subtotal gastrectomy under epidural anesthesia. Fasting blood glucose (FBG), fasting insulin (FINS) and serum proteins were assayed preoperatively and at day 1, 3, 7 postoperatively. Insulin resistance index was calculated using homeostasis model assessment (HOMA). The length of hospital stay and postoperative complications were recorded respectively.

RESULTS(1)The levels of FBG, FINS, lnHOMA-IR (P<0.01,P<0.05) and the incidence of insulin resistance were remarkably decreased by intensive insulin therapy after the surgical procedure.(2)The levels of serum transferrin (TRF), prealbumin (PRE) and retinal binding protein (RBP) in the intensive insulin therapy group were significantly improved as compared to control group after operation(P<0.05). (3) The duration of fever, antibiotic use, passage of gas by anus, length of hospital stay and the occurrence of postoperative complications were also significantly lower than those in control group(P<0.01,P<0.05).

CONCLUSIONCompared to routine therapy, the intensive insulin therapy has more beneficial effects on the patients undergone distal radical subtotal gastrectomy in decreasing the insulin resistance, improving the status of nutrition and preventing postoperative complications.

OBJECTIVETo investigate the value of CT and X-ray enterography in the diagnosis of small intestinal Crohn disease(CD).

METHODSData of 39 CD cases confirmed by surgery and pathology who underwent CT and X-ray enterography were analyzed retrospectively. All the patients had complete CT data, 28 cases had X-ray intestinal barium meal data, and 18 had sinus tract enterography.

RESULTSCT enterography showed mural thickening(>4 mm) in 34(87.2%) patients, mural gas in 7(17.9%), mural edema in 7(17.9%), mural fat in 4(10.3%), increased enhancement of bowel wall(>10 HU) in 37(94.9%), multiple segmental lesions in 33(84.6%), single segmental lesions in 6(15.4%), mesenteric lymphadenopathy(>5 mm) in 13(33.3%), vascular bundle thickening in 9(23.1%), cellulitis in 12(30.8%), peritoneal abscess in 10(25.6%), phlegmon in 8(20.5%), incomplete intestinal obstruction in 14(35.9%), seroperitoneum in 22(56.4%), and fistulization in 4(10.3%). CT enterography did not demonstrate the change of mucosa such as strip ulcer or cobblestone. Among the 28 cases of small bowel X-ray enterography, 23 cases(82.1%) presented with multiple segmental lesions, 5(17.9%) with single segmental lesions, 18(64.3%) with strip ulcer, 16(57.1%) with cobblestones, 4(14.3%) with intestinal fistula, while no bowel wall and extraintestinal complication of CD disease was observed. Among the 18 cases of sinus tract enterography, 13 cases (72.2%) presented with intestinal fistula, 12(66.7%) with peritoneal abscess, 8(44.4%) with sinus tract.

CONCLUSIONSCT enterography can demonstrate exactly the diseased bowel wall and extraintestinal complication of CD disease, which is important to evaluate the extent of CD and guide the treatment, however strip ulcer and cobblestone sign cannot be demonstrated. The X-ray enterography is available to demonstrate the characteristic changes of CD such as trip ulcers and cobblestones, but is difficult to show the bowel wall and extraintestinal inflammatory mass and abscesses. The sinus tract enterography is easy to demonstrate the intestinal fistula and intra-abdominal abscess. Combination of these methods is more beneficial to guild the diagnosis and treatment.

OBJECTIVETo study the anti-inflammatory effect of resveratrol in primary cortical astrocyte cultures stimulated by lipopolysaccharide (LPS) and explore the underlying mechanism of this protective effect.

METHODSThe astrocytes were cultured in the presence of resveratrol at different concentrations for 12 h followed by stimulation with lipopolysaccharide (LPS) for another 24 h. Lactate dehydrogenas (LDH) leakage volumes were detected, the cytotoxicity of resveratrol was examined using cell counting kit-8 (CCK-8), the release of NO was measured by Griess reaction, and the expression levels of TNF-α and iNOS were measured using ELISA and Western blotting respectively.

RESULTSThe purity of the astrocytes cultured in vitro was (95.49∓1.86)%. LPS treatment increased LDH leakage and reduced the survival rate of the astrocytes, resulting also in significantly increased NO and TNF-α release and iNOS protein expressions. Within the concentration range of 5-50 µmol/L, resveratrol effectively improved the survival rate of the astrocytes and decreased LDH leakage with a dose-response relationship. Only 25 and 50 µmol/L resveratrol produced obvious inhibitory effect on NO and TNF-α release and iNOS expression, while 5 µmol/L resveratrol had no such effects.

CONCLUSIONHigh concentration of resveratrol can inhibit the release of inflammatory mediators and improve the inflammation injury induced by LPS in astrocytes, the mechanism of which may involve the inhibition of iNOS/NO expression pathway.
