AIM:To study the clinical effect of silica gel drainage tube combined with lomefloxacin hydrochloride eye ophthalmic gel in the treatment of lacrimal duct obstruction.METHODS:Totally 86 cases (138 eyes) of lacrimal duct embolism treated in our hospital from February to December 2015 were divided into 43 cases (68 eyes) as control group and 43 cases (70 eyes) of the observation group according to whether they were treated with lomefloxacin hydrochloride eye ophthalmic gel.Patients in the control group were treated with silica gel drainage, while the observation group was treated with lomefloxacin hydrochloride eye ophthalmic gel on the basis of the control group.The total effective rate, serum hypersensitivity C-reactive protein (h-CRP) level, complications and recurrence rate were observed and compared between the two groups.RESULTS:The total effective rate in the patients with obstructive nasolacrimal duct, common lacrimal duct obstruction, and lacrimal duct obstruction in observation group were 95.2%, 100.0%, 96.7%, higher than those in control group (P<0.05).There was no significant difference between the two groups in preoperative serum h-CRP levels (P>0.05).The serum levels of h-CRP in patients in the observation group at 3d and 7d after operation respectively were 2.40±0.84g/mL, 1.94±0.84g/mL, lower than those of control group at the same time (P<0.05).The complication rate of the observation group was 1.4%, which was lower than that of the control group (P<0.05).Follow up for 6-18mo, the recurrence rate was 11.4% in the observation group, which was significantly lower than the control group (P<0.05).CONCLUSION:The combination of silica gel drainage tube and lomefloxacin hydrochloride eye ophthalmic gel in the treatment of obstruction of lacrimal duct has good clinical efficacy, low inflammatory reaction, low complication rate and low recurrence rate.

The contribution of particles to cardiovascular mortality and morbidity has been enlightened by epidemiologic and experimental studies. However, adverse biological effects of the particles with different sizes on cardiovascular cells have not been well recognized. In this study, sub-cultured human umbilical vein endothelial cells (HUVECs) were exposed to increasing concentrations of pure quartz particles (DQ) of three sizes (DQPM1, <1 μm; DQPM3-5, 3-5 μm; DQPM5, 5 μm) and carbon black particles of two sizes (CB0.1, <0.1 μm; CB1, <1 μm) for 24 h. Cytotoxicity was estimated by measuring the activity of lactate dehydrogenase (LDH) and cell viability. Nitric oxide (NO) generation and cytokines (TNF-α and IL-1β) releases were analyzed by using NO assay and enzyme-linked immunoabsorbent assay (ELISA), respectively. It was found that both particles induced adverse biological effects on HUVECs in a dose-dependent manner. The size of particle directly influenced the biological activity. For quartz, the smaller particles induced stronger cytotoxicity and higher levels of cytokine responses than those particles of big size. For carbon black particles, CB0.1 was more capable of inducing adverse responses on HUVECs than CB1 only at lower particle concentrations, in contrast to those at higher concentrations. Meanwhile, our data also revealed that quartz particles performed stronger cell damage and produced higher levels of TNF-α than carbon black particles, even if particles size was similar. In conclusion, particle size as well as particle composition should be both considered in assessing vascular endothelial cells injury and inflammation responses induced by particles.

Objective: To observe the clinical efficacy of filiform fire-needling plus continuous passive motion (CPM) therapy for frozen shoulder. Methods: A total of 72 patients were randomized into an observation group and a control group by the random number table method, with 36 cases in each group. Patients in the control group received celecoxib capsule plus CPM, while those in the observation group received filiform fire-needling plus CPM. The whole course of treatment lasted for 2 weeks in both groups. The visual analog scale (VAS), Constant-Murley score (CMS) and range of motion of shoulder joint were measured for therapeutic efficacy evaluation. Results: The total effective rate was 91.7％ in the observation group, higher than 72.2％ in the control group, and the between-group comparison showed statistical significance (P<0.05). After treatment, the VAS scores in the two groups dropped significantly, the CMS as well as the range of motion including abduction, forward flexion and extension were all increased significantly, and the intra-group comparisons showed statistical significance (all P<0.05). The betweengroup comparisons showed the improvements in these items in the observation group were more significant than those in the control group (all P<0.05). Conclusion: Filiform fire-needling plus CPM can produce more significant efficacy than celecoxib capsule plus CPM for frozen shoulder; it can alleviate pain, improve shoulder function and restore joint range of motion in such patients.

OBJECTIVETo construct the eukaryotic expression vector of HBEBP1 gene and express HBEBP1 recombinant protein in yeast.

METHODSPCR was performed to amplify the gene of HBEBP1 from the cDNA template origining from HepG2, and the gene was cloned into pGEM-T vector. After sequencing, the correct DNA fragment was cut from pGEM-T-HBEBP1 and inserted into yeast expression plasmid pGBKT7. The reconstructed plasmid pGBKT7-HBEBP1 was transformed into yeast cell AH109 and screened on the synthetic dropout nutrient medium (SD/-Trp/Kana). The yeast protein was isolated and analyzed with SDS-PAGE and Western Blot.

RESULTSThe eukaryotic expressive vector was constructed successfully. The results of Western Blot showed HBEBP1 protein was existed within yeast cells and the molecular weight of it was about 33 x 10(3).

CONCLUSIONSThe successful expression of HBEBP1 protein in yeast cells lay the foundation for studying biological function of HBEBP1.

OBJECTIVETo evaluate the efficacy,clinical benefits and toxicities of gemcitabine combined with erlotinib for advanced pancreatic cancer.

METHODClinical data of 20 patients with advanced pancreatic cancer treated with gemcitabine 1000 mg/m2 on day 1 and day 8 (repeated every 21 days) plus erlotinib 100-150 mg/d at Peking Union Medical College Hospital was reviewed retrospectively.

RESULTSNo patient achieved complete remission or partial remission, 11 patients (55%) had stable disease, and 9 patients (45%) experienced disease progression. The disease control rate was 55%, and clinical benefit rate was 30%. The median progression free survival was 4.0 months, and the median overall survival was 8 months. The total incidence of hematologic toxicity was 70%, including 15% of grade 3-4 leucopenia and 5% of grade 3-4 thrombocytopenia. Eleven patients (55%) had rash, which were all grade 1-2. One patient had grade 2 diarrhea and five had grade 1 transaminase elevation. No chemotherapy-related death occurred.

CONCLUSIONSGemcitabine combined with erlotinib is an effective regimen for pancreatic cancer with good clinical tolerance. The most common adverse events are hematologic toxicities and rash.

OBJECTIVETo evaluate the efficacy and safety of irinotecan combined with xeloda (CAPIRI regimen) in patients with metastatic colorectal cancer after failure of chemotherapy with oxaliplatin.

METHODSTotally 38 patients with metastatic colorectal cancer after failure of chemotherapy with oxaliplatin were enrolled. Patients received xeloda 1 000 mg/m2 orally twice daily on day 1 to 14 and intravenous irinotecan 100 mg/m2 on day 1 and 8 every 3 weeks.

RESULTSThe median age of 38 patients was 58.5 (27-77) years. CAPIRI regimen was used 11.0 (3.0-24.0) months after the diagnosis of metastatic colorectal cancer (CAPIRI regimen as second-line chemotherapy in 33 patients, third-line in 4 patients, and fourth-line in 1 patient). A total of 121 cycles of chemotherapy (median 3.0) were administered. Thirty-four patients were evaluable for response. The overall response rate and disease control rate were 5.9% and 61.8%, respectively. The median time to progression and overall survival were 4.5 months (95% CI, 3.4-5.6 months) and 11.0 months (95% CI, 10.2-11.8 months), respectively. All 38 patients were evaluable for safety. The most common adverse events were leukopenia (73.7%), neutropenia (65.8%), nausea and vomiting (60.5%), and diarrhea (28.9%). The occurrence rates of these grade 3-4 events were 10.5%, 13.2%, 10.5%, and 7.9%, respectively. All adverse events were tolerable.

CONCLUSIONCAPIRI regimen is effective and well-tolerated in Chinese patients with metastatic colorectal cancer after failure of chemotherapy with oxaliplatin.
