Objective To discuss different effect of periocular injection and subconjunctival injection in treatment of iridocyclitis. Methods Eighty people with iridocyclitis were divided into group A and group B according to their admission order. Group A adopted periocular injection and group B was given subconjunctival injection. The incidence of complication was compared between the two groups. Results Significant difference existed in complications and related factors between two groups after treatment, periocular injection proved to be superior to subconjunctival injection. Conclusions Periocular injection is a desirable treatment method for iridocyclitis. It is easy to operate, safe, rapid and with less pain, so it is worthy of clinical application.

Objective To investigate effects of α-crystallin on proliferation of lipopolysaccharide (LPS)-activated retinal microglia and bioactivity of iNOS.Methods The retinal microglial cells cultured in vitro were analyzed and their purity was identified by cell immunofluorescence and flow cytometry.After microglia cells being intervened using LPS and α-crystallin at various concentrations,influence of α-crystallin on activity of LPS-activated retinal microglia was detected by MTT method and level of NO was measured by RT-PCR to observe changes of iNOS expression in microglia.Results Purity of primary cultured microglial cells was 94.15％ by GSA-IB4 immunohistochemical identification and 93.34％ by CD11b flow cytometry.α-crystallin of 10-4g/L awakened activity of microglia induced by 10-6g/L LPS (P ＜ 0.01).Expressions of iNOS protein and mRNA showed significant decrease in combined treatment group (P ＜ 0.05).Conclusion In clinical condition,α-crystallin decreases the harm of microglial cells on retinal ganglial cells (RGCs) after optical nerve injury by inhibiting the microglia cells to produce NO and iNOS.

[ ABSTRACT] AIM:To observe the effect of ginsenoside Rb 1 on the proliferation and the expression of serotonin transporter (SERT), 5-hydroxytryptamine 1B receptor (5-HT1BR) in rat pulmonary artery smooth muscle cells (PASMCs) under hypoxia condition and the relationship with Rho /Rho-kinase signal pathway .METHODS: PASMCs were isolated from the adult male SD rats and primarily cultured .The subcultured cells from the 4th generation to the 6th generation were harvested and divided into normal group , and hypoxia group , different concentrations of Rb 1 incubation groups treated with 50, 100 and 200 mg/L ginsenoside Rb1 under hypoxia (HR50, HR100 and HR200 groups, respectively).The viability of the PASMCs was measured by CCK-8 assay.BrdU positive cells were determined using flow cytometry .The expression of serotonin transporter and 5-HT1BR at mRNA and protein levels was detected by RT-PCR and Western blot, respectively. The PASMCs were randomly divided into normal group , hypoxia group , HR200 group and hypoxia +Y-27632 incubation group ( HY group ) .The mRNA expression of Rho-kinase and phosphorylated myosin phosphatase target subunit 1 ( p-MYPT1) protein level were investigated by RT-PCR and Western blot, respectively.RESULTS: Compared with normal group, the proliferation of PASMCs in hypoxia group was significantly increased (P<0.01).The cell viability and the ex-pression of SERT and 5-HT1B R at mRNA and protein levels in all different concentrations of Rb 1 groups were obviously de-creased compared with hypoxia group ( P<0.05 ) .The mRNA expression of Rho-kinase and protein level of p-MYPT1 were markedly decreased in HR200 group, and no significant difference compared with HY group was observed ( P <0.01).CONCLUSION: Treatment with ginsenoside Rb1 might prevent hypoxia-induced proliferation of PASMCs and over-expression of SERT and 5-HT1B R through inhibiting the Rho/Rho-kinase pathway .

ObjectiveTo determine thallium in whole blood by atomic absorption detection method, and to investigate the eliminating effect of hemoperfusion (HP) for thallium in blood.Methods The blood of Beagle dogs which had not exposed to thallium before were obtained for preparation of thallium nitrate (TlNO3)-containing solution in three concentrations according to the conversion formula based on animal weight and volume of blood. HP was performed in the simulated in vivo environment. The content of TlNO3 in blood of the next group was determined on the amount of TlNO3 for the last HP of the former dose group. Thallium quantity in different samples was measured with atomic absorption spectrometer blood samples before and after HP. Finally, the thallium concentration in blood was analyzed statistically.Results Thallium concentrations showed a good linear relationship in the range of 0-200μg/L (r = 0.998 4). The intra-day precision (RSD) was lower than 4.913%, the intra-day recovery rate was 96.2%-111.9%; the inter-day precision (RSD) was lower than 7.502%, the inter-day recovery rate was 89.6%-105.2%. The concentration of thallium in blood was significantly reduced after HP per time in high, middle, and low dose groups [(453.43±27.80) mg/L to (56.09±14.44) mg/L in high dose group,F = 8.820,P = 0.003;(64.51±13.60) mg/L to (3.19±0.23) mg/L in middle dose group,F = 36.312,P = 0.000; (5.40±0.98) mg/L to (0.38±0.25) mg/L in low dose group,F = 46.240,P = 0.000]. The adsorption rate of four times of HP in high, middle and low dose group were (87.63±2.48)%, (95.06±1.54)% and (92.76±4.87)%, respectively, without significant difference (F = 4.231,P = 0.070 ).Conclusions The method for measuring thallium was established, and it shows a very stable, simple, sensitive for determination of thallium. HP can effectively remove thallium from blood. Thallium concentration can be reduced by 90% after four times of HP. HP is also effective even when thallium concentration is not high.

Acute respiratory distress syndrome (ARDS), a common respiratory critical illness with multiple causes, is associated with high mortality. The high degree of heterogeneity may be the reason why it is lack of highly specific and sensitive biological biomarkers. Therefore, it is an urgent need to explore biomarkers, perform phenotypic analysis and establish risk stratification model for diagnosis, prognosis, and treatment of ARDS. Endothelial cells specificity molecular-1 (ESM-1, endocan), is a soluble dermatan sulfate proteoglycan, and be involved in regulating biological behaviors such as cell proliferation, differentiation and migration. Numerous studies have confirmed that ESM-1 is closely related to inflammation, endothelial activation and dysfunction. However, the role of ESM-1 in the initiating and developing process of ARDS is still unclear. To provide a scientific basis for its clinical applications in ARDS, such as early prognosis assessment and timely prevent strategies, this paper focuses on the biological properties and the clinical value of ESM-1 as a potential biomarker for ARDS.

Objective:To compare the adjuvant chemotherapy project and survival prognosis of patients with stage Ⅱ/Ⅲ colon cancer in different age groups.Methods:In this retrospective study, the clinical data of 770 colon cancer patients undergoing radical resection were collected in the First Affiliated Hospital of Soochow University from Jan 2013 to Dec 2017. Patients were categorized into 3 groups based on age at onset of colon cancer: young group (18-49 years old, 112 cases), middle-aged group (50-64 years old, 351 cases) and older group (65-75 years old, 307 cases).Results:The young group had fewer complications, and the probability of cancer deposit, vascular tumor thrombus and nerve invasion was lower than the middle-aged and older group (12.5% vs. 15.4% vs. 14.3%; 7.1% vs. 9.4% vs. 8.5%; 2.7% vs .8.8% vs. 5.5%), but the probability of signet-ring cell carcinoma and mucinous adenocarcinoma was higher (5.4% vs. 1.4% vs. 1.6%; 14.3% vs. 11.4% vs. 13.4%), the proportion of patients with stage Ⅲ was greater (49.1% vs. 45.0% vs. 47.2%), and they were more willing to receive postoperative chemotherapy (83.9% vs. 81.8% vs. 60.3%). Among patients with stage Ⅱ and Ⅲ colon cancer, the young group and the middle-aged group were 3-4 times more likely to receive adjuvant chemotherapy than the elderly group [ OR=4.153 (95% CI:1.964-8.785), 2.906 (95% CI:1.845-4.579), 3.120 (95% CI:1.310-7.429), 3.588 (95% CI: 1.964-6.556)]. Of those patients who received chemotherapy, young and middle-aged patients had a higher percentage of multiagent regimen use than older patients [ OR=2.050 (95% CI:0.937-4.488), 2.750 (95% CI:1.536-4.923)]. Among patients treated with surgery alone, no significant differences were observed in survival among age groups. Among patients who received surgery and adjuvant chemotherapy, a significantly better survival was observed for young and middle-aged patients with stage Ⅲ [ HR=0.284 (95% CI:0.127-0.632), 0.521 (95% CI:0.333-0.816)] than their older counterparts. Conclusions:Among patients with stage Ⅱ/Ⅲ colon cancer, young and middle-aged patients are more likely to undergo adjuvant chemotherapy and use more radical chemotherapy regimen. Young and middle-aged patients with stage Ⅱ colon cancer had overuse of chemotherapy, but did not result in expected survival improvement.
